For many years, researchers in the field of autoimmunity have focused on the role of the immune components in the etiopathogenesis of autoimmune diseases. However, some studies have demonstrated the importance of target tissues in their pathogenesis and the breach of immune tolerance. The immune system as well as target tissue cells (plasmatic, β-pancreatic, fibroblast-like synoviocytes, thyroid follicular and epithelial cells of the lachrymal glands, salivary glands, intestine, bronchioles and renal tubules) share the characteristic of secretory cells with an extended endoplasmic reticulum (ER). The function of these cells depends considerably on a normal ER function and calcium homeostasis, so they can produce and secrete their main components, which include glycoproteins involved in antigenic presentation such as major histocompatibility complex (MHC) class I and II. All these proteins are synthesized and modified in the ER, and for this reason disturbances in the normal functions of this organelle such as protein folding, protein quality control, calcium homeostasis and redox balance, promote accumulation of unfolded or misfolded proteins, a condition known as ER stress. Autoimmune diseases are characterized by inflammation, which has been associated with an ER stress condition. Interestingly, patients with these diseases contain circulating auto-antibodies against chaperone proteins (such as Calnexin and GRP94), thus affecting the folding and assembly of MHC class I and II glycoproteins and their loading with peptide.The main purpose of this article is to review the involvement of the protein quality control and unfolded protein response (UPR) in the ER protein homeostasis (proteostasis) and their alterations in autoimmune diseases. In addition, we describe the interaction between ER stress and inflammation and evidences are shown of how autoimmune diseases are associated with an ER stress condition, with a special emphasis on the second most prevalent autoimmune rheumatic disease, Sjögren's syndrome.

IntroductionBehçet disease (BD) is a systemic vasculitis involving vessels from any size with various clinical features. Most BD cases are multifactorial and associated with the HLA B51 antigen. In rare and severe early onset cases, dominant Mendelian transmission has been linked to mutations in the TNFAIP3 gene encoding A20. Herein, we propose a systematic review of the literature about the haploinsufficiency A20 (HA20) published cases.Systematic reviewOur review of the 45 cases of HA20 from literature highlights the similarities and the differences between this genetic auto-inflammatory disease and classical BD. HA20 looks like BD if we consider recurrent oral (87%) and genital (67%) ulcers, arthralgia or arthritis (42%), skin involvement (53%) such as erythema nodosum or abdominal symptoms (60%) such as abdominal pain, digestive ulcers or diarrhea. However, HA20 differs from classical BD because its geographical distribution is ubiquitous, sex ratio is inversed (one man for two women), first symptoms occur in early childhood (median age = 5.5 years; interquartile range: 1–10) instead of adulthood, recurrent fever is common (62%) unlike classical BD, HLA B51 antigen is uncommon and abdominal symptoms are over-represented compared to classical BD. In addition, response to colchicine in HA20 is inconstant (24%) unlike classical BD.Discussion/conclusionHigh fever flares and digestive involvement starting in early childhood seem to be hallmarks of HA20 clinical features. Response to colchicine is unpredictable and biotherapies like anti-TNFα and anti IL1 appear to be treatments of choice, like for other auto-inflammatory diseases. Prospective description of larger cohort of HA20 cases is needed to understand better when this disease must be looked for and how to treat these patients.

What is blocking early peanut introduction?

Peanut allergy affects up to 2% to 4% of US children,1,2 and prevalence appears to be increasing.3 Most (approximately 75–80%) retain peanut allergy and risk for anaphylaxis into adulthood.4 Recognizing the burden of peanut allergy, professional societies advised dietary interventions in infants and young children to lower risk of developing peanut allergy. Based on a changing body of evidence during the past 2 decades, guidelines have shifted from delayed introduction of allergenic foods to early and sustained ingestion of peanut.

Atopic dermatitis

In the current issue of the Annals, Bridgman et al1 provide an overview on the multidimensional burden of atopic dermatitis (AD). It is clear from this perspective that patients with AD are affected in multiple ways, leading to impaired quality of life and social functioning, low self-esteem, more sick days, reduced physical activity, and academic and work impairment. These effects lead to disruption not only of the patients' lives but that of their families, with increased feelings of helplessness, stress, and low general life satisfaction.

The many faces of eczema and its treatments

Atopic dermatitis (AD), contact dermatitis, and irritant dermatitis share many similarities, and are often tied together in a Gordian knot of etiopathogenesis and therapeutic considerations. The pruritus, eczematous morphology, and waxing-waning presentations can be clinically indistinguishable, and as more of the scientific underpinnings are elucidated, connections in their complex pathophysiology continue to be found.1,2 Differentiating between these entities, especially when more than 1 may be present simultaneously, can be a daunting task.

Paul Klenerman's The Immune System, A Very Short Introduction, is aptly titled and yet quite useful. Klenerman skillfully explains and summarizes an intricate and complex system into a short read that can certainly be completed in an afternoon. This brief book presents a helicopter view of the immune system, or perhaps more accurately a seagull's view, as it occasionally dives down deeper to take a closer look between arching overviews. A broad range of readers will be able to glean some utility from the book, because it offers important concepts in a fun, informative, and concise read.

Galectin-7 (Gal-7) has been associated with cell proliferation and apoptosis. It is known that Gal-7 antagonises TGFβ-mediated effects in hepatocytes by interacting with Smad3. Previously, we have demonstrated that Gal-7 is related to CD4+ T cells responses; nevertheless, its effect and functional mechanism on CD4+ T cells responses remain unclear. The murine CD4+ T cells were respectively cultured with Gal-7, anti-CD3/CD28 mAbs, or with anti-CD3/CD28 mAbs & Gal-7. The effects of Gal-7 on proliferation and the phenotypic changes in CD4+ T cells were assessed by flow cytometry. The cytokines from CD4+ T cells were analysed by quantitative real-time PCR. Subcellular localisation and expression of Smad3 were determined by immunofluorescence staining and Western blot, respectively. Gal-7 enhanced the proliferation of activated CD4+ T cells in a dose- and β-galactoside-dependent manner. Additionally, Gal-7 treatment did not change the ratio of Th2 cells in activated CD4+ T cells, while it increased the ratio of Th1 cells. Gal-7 also induced activated CD4+ T cells to produce a higher level of IFN-γ and TNF-α and a lower level of IL-10. Moreover, Gal-7 treatment significantly accelerated nuclear export of Smad3 in activated CD4+ T cells. These results revealed a novel role of Gal-7 in promoting proliferation and Th1/2 cells polarization toward Th1 in activated CD4+ T cells by inhibiting the TGFβ/Smad3 pathway.

BackgroundBronchial hyperresponsiveness (BHR), one of the key features of asthma, shows a diverse natural course in school-aged children, but, studies on BHR phenotypes are lacking.ObjectiveWe classified BHR phenotypes according to onset age and persistence in children and investigated the characteristics and factors associated with each phenotype in a longitudinal study.MethodsWe analyzed 1,305 elementary school children from the Children's HEalth and Environmental Research (CHEER) study, a 4-year prospective follow-up study with 2-year intervals starting at a mean age of 7 years. Total serum IgE levels and blood eosinophils (%) were measured, and allergy work-up including methacholine challenge tests with ISSAC questionnaire were performed at each survey.ResultsWe classified the four BHR phenotypes as non-BHR (n=942, 72.2%), early-onset transient BHR (n=201, 15.4%), late-onset BHR (n=87, 6.7%), and early-onset persistent BHR (n=75, 5.7%). Early-onset persistent BHR is characterized by an increased eosinophils (%), total serum IgE level, sensitization rate, a decreased lung function and an increased risk of newly diagnosed asthma during follow-up (aOR, 3.89; 95% CI, 1.70-8.88). The two early-onset phenotypes were associated with peripheral airway dysfunction. The late-onset BHR phenotype related with increased risks of AR symptoms at baseline and later sensitization against inhalant allergens.ConclusionThe early-onset persistent BHR phenotype in school-aged children is associated with high atopic burden and increased risk of newly diagnosed asthma, whereas the late-onset BHR phenotype related with later sensitization and AR symptoms. Diverse BHR phenotypes in children have specific characteristics that require targeted follow-ups.

Voice Changes in the Elderly

The impact of aging is as inevitable in the larynx as on all biologic systems. The muscles of larynx have the potential to atrophy, the elastin fibers of lamina propria thin with age, and mucous production diminishes. As a result, vocal folds fail to approximate appropriately and the stress on once-robust vocal folds increases. These changes present as poor voice quality, vocal tension, tremor, and altered fundamental frequency. Rather than consider presbyphonia as an immutable diagnosis, we must see it as an opportunity to elevate our standard of care and set goals to work for therapeutic improvement of voice quality.

Rhinoplasty for South East Asian Nose

The South East Asian nose is usually small with voluminous thick skin, low dorsum, wide and hanging ala, bulbous tip, and retracted premaxilla. The surgical approach of rhinoplasty for these types of noses includes the following: dorsal augmentation, counterrotation and projection of the tip, and correction of hanging ala and alar flare/base. A usual ideal rhinoplasty outcome of a South East Asian nose should be a nose that fits the face with good function and has all the aesthetic landmarks achieved: natural looking dorsum, supratip break, tip, subtip break, columellar show, good alar-columellar relationship, improved premaxilla, improved nostril, and improved alar flare.

Updating nasalisation: From concept to technique and results

Publication date: Available online 7 June 2018

Author(s): R. Jankowski, C. Rumeau, D.T. Nguyen, P. Gallet
Nasalisation is a surgical technique proposed for the treatment of nasal polyposis in 1995. The technique as initially described was based on large opening of the maxillary, sphenoidal and frontal ostia and resection of the middle turbinates, with the aim of resecting the mucosa of the lateral masses of the ethmoid as completely and safely as possible. Recent findings on the evolution and development of the nose and sinuses and sinus physiology allow both the concept and the technique of nasalisation to be updated. According to evo-devo theory, the ethmoid is not a paranasal sinus but the skull-base bone housing the olfactory mucosa. In humans, the olfactory mucosa can be distinguished as functional in the upper recess of both olfactory clefts and vestigial in the rest of the ethmoid bone. Nasal polyposis presents clinically as a specific disease of the vestigial olfactory mucosa of the human ethmoid (and not as a particular kind of chronic rhinosinusitis). The aim of surgery for nasal polyposis is thus maximal resection of the vestigial olfactory mucosa, conserving olfactory function as long as possible. By the production, storage and bolus release of nitric oxide thanks to the sphincter function of the paranasal (maxillary, sphenoidal and frontal) sinus ostia, the paranasal sinuses perform a respiratory function that should be conserved as much as possible. The nasalisation technique has been modified in order for the vestigial olfactory mucosa to be completely resected while sparing the sinus ostia. Middle turbinate surgery still needs to be evaluated: resection is a step toward maximal removal of vestigial olfactory mucosa, while conservation could ensure olfactory cleft integrity. Thus, updating the concept of nasalisation enables the nasalisation technique to be integrated in the evo-devo concept of rhinology.

Nasal septal abscess caused by anaerobic bacteria of oral flora

Publication date: Available online 7 June 2018
Source:Auris Nasus Larynx
Author(s): Yukiyoshi Hyo, Hisaki Fukushima, Tamotsu Harada, Hirotaka Hara
Although nasal septal abscess (NSA) was formerly common, it has become rare since the development of antibiotics. NSA, if left untreated, can lead to intracranial complications such as meningitis and eventually result in saddle-nose deformity. NSA often occurs after injury, and indigenous skin bacteria such as Staphylococcus aureus are frequently detected. We treated a patient who had injured the upper alveolus in a fall on the stairs and developed NSA two weeks later. Anaerobic bacteria, including Veillonella parvula and Peptostreptococcus sp., were detected. Symptoms were relieved by needle and incisional drainage. Our patient represents a very rare case of NSA in terms of the cause of onset and the detected bacteria. Early drainage can result in good outcomes.

An incredibly dilated Wirsung mimicking a sero-cystic neoplasm of the pancreatic head

Abstract

A diabetic patient who at a routine abdominal ultrasounds was found to have a very dilated pancreatic duct. Computed tomography (CT) scan diagnosed a sero-cystic lesion of the pancreatic head. Gastroduodenoscopy discovered a duodenal hyperemic area, which was sampled. Biopsy demonstrated intramucosal vascular emboli from a neuroendocrine carcinoma positive for Chromogranin A and Somatostatin and negative for Gastrin. Cholangio-magnetic resonance imaging revealed that the sero-cystic lesion found at CT, was being mimicked by the enormously dilated pancreatic duct but suggested the possibility of an intraductal or ampullar neoplasm. Blood and urine tests were not helpful and an octreoscan was negative. The patient underwent surgery. Direct exploration confirmed the severe pancreatic duct dilation and a cephalic lesion requiring a pancreatoduodenectomy. Histology confirmed a neuroendocrine tumor infiltrating the duodenum. We conclude that despite modern sophisticated imaging and endoscopic techniques, the evaluation of bilio-pancreatic region can be challenging and can reserve surgical surprises.

Heterotopic ossification following use of i-Factor for spinal fusion in Mucopolysaccharidosis 1: a case report

Abstract

Mucopolysaccharidosis is a rare group of genetic disorder which results in a complex of anomalies involving various systems. In Mucopolysaccharidosis 1 progressive thoracolumbar kyphosis is a common presentation which can result in instability and neurological deficit. Posterior spinal surgery is performed to correct deformity and obtain spinal fusion. Peptide enhanced bone graft substitute (i-Factor^TM) is relatively a new component with proven efficacy to obtain early spinal fusion. An 8-year-old child with progressive high lumbar kyphosis due to Mucopolysaccharidosis 1 was admitted for Posterior spinal fusion with i-Factor bone graft substitute. Postoperatively patient had serous discharge from the wound which settled without intervention. A month after the surgery spinal radiographs revealed heterotopic ossification at the distal end of spinal construct in the paraspinal region. Patient remained asymptomatic and clinically well.

Thinking outside the rectum: a unique approach to the retrieval of gluteal foreign bodies

Abstract

Penetrating gluteal wounds with retained foreign bodies are relatively uncommon and therefore there is no agreed-upon method of extraction. Retrieval of such objects can be difficult to achieve due to imperfect anatomy and a lack of clear planes across which the objects traverse, sometimes requiring novel techniques for foreign body retrieval. We saw a 37-year-old male with a 2-month history of a draining abscess on his right buttock. CT and manual probing of the wound demonstrated a 5-cm tract with a possible foreign body within. We took the patient to the operating room for exploration of the tract under general anesthesia, allowing for palpation of the foreign object as well as digital rectal exam, which identified an object passing posterior to the rectum. A cystoscope was used to widen the tract and allow for better visualization. Grasping forceps were inserted into the cystoscope and used to capture/retrieve the object.

IntroductionSystemic inflammatory biomarkers are promising predictive and prognostic factors for solid cancers. The neutrophil–lymphocyte ratio and derived neutrophil–lymphocyte ratio are used to predict inflammation and used as biomarker in several malignancies.ObjectiveThe purpose of this study was to demonstrate the diagnostic, predictive and prognostic role of neutrophil–lymphocyte ratio and derived neutrophil–lymphocyte ratio in patients with laryngeal neoplasms.MethodsA retrospective study was conducted on medical records involving 229 patients with benign, premalignant and malignant laryngeal neoplasms between 2002 and 2015. The diagnostic, predictive and prognostic role of neutrophil–lymphocyte ratio and derived neutrophil–lymphocyte ratio were evaluated using uni– and multivariate analysis.ResultsThe neutrophil–lymphocyte ratio and derived neutrophil–lymphocyte ratio were not statistically different between patients with benign, premalignant and malignant laryngeal neoplasms. Both neutrophil–lymphocyte ratio and derived neutrophil–lymphocyte ratio were predictive factors for stage, lymph node metastasis, and distant metastasis. Patients with high neutrophil–lymphocyte ratio value (≥4) had a poor prognosis when compared with patients with low neutrophil–lymphocyte ratio value (5 year, Overall Survival: 69.0% vs. 31.1%, p<0.001; 5 year, disease free survival: 70.0% vs. 32.7%, p˂0.001; 5 year, locoregional recurrence free survival: 69.7% vs. 32.0%, p<0.001). Furthermore, neutrophil–lymphocyte ratio was an independent prognostic factor for 5 year: Overall survival (HR=2.396; 95% CI 1.408–4.077; p=0.001), Disease free survival (HR=2.246; 95% CI 1.322–3.816; p=0.006) and locoregional recurrence free survival (HR=2.210; 95% CI 1.301–3.753; p=0.003).ConclusionPretreatment neutrophil–lymphocyte ratio is a useful and reliable predictive and prognostic biomarker for patients with laryngeal carcinoma.

Subcutaneous emphysema to the head and neck: an unlikely traumatic origin

Subcutaneous emphysema to the neck represents a rare entity mainly derived from iatrogenic and traumatic origin. We report a case of a subcutaneous emphysema resulted from an intraoral injury aiming to emphasise the significance of precise medical history to identify an unlikely mechanism. A 40-year-old female patient was presented with subcutaneous emphysema extending from the region underneath the left eye up to the submandibular area of the neck. The patient complained of painful, swollen neck. The patient mentioned that the symptoms began after an intraoral injury accidentally caused by the use of a high-pressure water jet device meant for car wash. The patient was managed conservatively and was discharged after 2 days. This case highlights the urgency for clinical suspicion for unlikely mechanisms. Moreover, the manufacturer companies should alert and give official warning for the contingency of injury due to incorrect or careless usage.

Terminal deoxynucleotidyl transferase (TdT)-negative T-cell lymphoblastic lymphoma with loss of the T-cell lineage-specific marker CD3 at relapse: a rare entity with an aggressive outcome

Terminal deoxynucleotidyl transferase (TdT)-negative T-cell lymphoblastic lymphoma is a variant of T-cell lymphoblastic lymphoma/T-cell lymphoblastic leukaemia. TdT is a marker of immaturity expressed in 90%–95% cases of lymphoblastic lymphoma and useful in differentiating it from other mature lymphomas/leukaemias. It has been associated with poorer response to chemotherapy and a more aggressive outcome. Here we present a case of TdT-negative T-cell lymphoblastic lymphoma in a 28-year-old man who presented with superior vena cava syndrome. The patient was treated with hyper-cyclophosphamide,vincristine, Adriamycin, dexamethasone (CVAD), however unfortunately suffered a relapse 1 year later. A unique feature of our case was that on relapse, the patient lost expression of the T-cell lineage-specific marker CD3, which has previously not been reported in association with TdT-negative T-cell lymphoblastic lymphoma. The patient failed to respond to chemotherapy on his relapse and died.

Novel psychoactive substances: overdose of 3-fluorophenmetrazine (3-FPM) and etizolam in a 33-year-old man

Though illegal in the UK, in many countries novel psychoactive substances are quasi-legal synthetic compounds that are widely available online under the guise of research chemicals. These substances are relatively cheap and are often undetectable in standard drug screens. Nearly 200 such compounds are introduced yearly, and little is usually known about their metabolism or physiological effects. Consequently, managing patients in overdose situations on largely unknown substances usually involves supportive care, however anticipating and managing atypical side effects are challenging in the absence of knowledge of these compounds. In this report, we discuss our encounter with a 33-year-old unconscious man presenting with coingestion of a novel stimulant 3-fluorophenmetrazine with a rarely used benzodiazepine etizolam. This patient developed seizure-like activity and delayed widespread T-wave inversions, both of which ultimately resolved without sequelae.

Acyclovir-induced thrombocytopaenia in a patient with SLE

Acyclovir has been used in the treatment of herpes simplex and varicella zoster viral infections for over 30 years. The side effects of oral treatment at standard doses are rare and include headache, diarrhoea, dizziness and malaise. We report a patient with a new diagnosis of systemic lupus erythematosus (SLE) who developed thrombocytopaenia within days on a therapeutic dose with acyclovir. Prompt discontinuation of acyclovir and treatment with intravenous immunoglobulin resulted in reversal of the above potentially serious complication. Therefore a high index of suspicion should be exercised in patients with SLE who require treatment with acyclovir for herpes viral infections. In these patients regular platelet count measurement should be considered while on treatment with the above antiviral agent.

Orbital cysticercosis

A young male patient presented to our ocular emergency department with chief complaints of progressive pain, redness, diplopia and a right-sided face turn. Ocular examination revealed severely restricted extraocular movements along with retinal folds in the left eye. Initial orbital ultrasound and CT findings were equivocal; however, serology favoured an infective cause. Considering the endemicity of the disease and equivocal investigation findings, a diagnosis of orbital cysticercosis with an atypical presentation was made. The patient was managed medically with a combination of oral albendazole and steroids over a period of 6 weeks to achieve optimal results.

Babesiosis as a cause of false-positive HIV serology

This is a case of a 71-year-old homosexual man who presented with a 4-day history of fever, weakness and headaches, near syncope, nausea and poor oral intake. The patient denied recent travel or sick contacts but had significant tick bites in the last 4 weeks. A peripheral blood smear showed 0.5% parasitaemia with signet ring appearance organisms consistent with Babesia microti. Serology testing for HIV 1 and 2 by ELISA and western blot were positive. Treatment for Babesia was started and the patient improved. Repeat serology testing for HIV was negative. To the best of our knowledge, this is the first case of false-positive HIV serology that is associated with active babesiosis. In this case, the positive HIV serology turned negative after successful treatment of babesiosis.

Management of flares of disease during pregnancy can be complex and there are few case reports of pregnant women with acute severe ulcerative colitis (ASUC). We present the case of a 31-year-old pregnant woman who at 16 weeks gestation developed ASUC in the context of primary non-response to infliximab therapy. She subsequently underwent an emergency laparoscopic colectomy after failing to respond to hydrocortisone and cyclosporine salvage therapy. Her pregnancy was further complicated by HELLP (Haemolysis, Elevated liver enzymes and Low Platelets) syndrome resulting in premature delivery at 27 weeks gestation. This case highlights the management issues involved in ASUC during pregnancy and the assessment of disease activity, use of salvage therapies, and provides a framework to approach this complex medical emergency.

Obstructive hydrocephalus caused by colloid cyst presenting as a schizophrenia-like psychosis

This report presents a young woman with psychotic symptoms that were highly suspicious of schizophrenia. Previous attempts of antidepressant therapy of mood symptoms had been ineffective. However, she also presented with discrete signs of an underlying neurological condition, and as a part of the diagnostic workup, neuroimaging revealed ventriculomegaly. She was diagnosed with obstructive hydrocephalus and experienced full remission of psychotic symptoms after neurosurgical intervention with a ventriculoperitoneal shunt. This atypical presentation of obstructive hydrocephalus underlines the importance of neuroimaging in psychiatric differential diagnostics. Otherwise, this young woman had been diagnosed with schizophrenia, instead of organic delusional disorder secondary to a neurological condition, with possible irreversible damage to brain tissue as a consequence.

Concomitant sarcoidosis and papillary thyroid cancer with severe hypercalcaemia as the main symptom

A 65-year-old Caucasian man was admitted to our hospital due to incidental finding of plasma ionised calcium=1.83 mmol/L. During the previous months, he had felt more tired and had experienced an unintended weight loss of 6–8 kg. A CT scan revealed an inhomogeneous thyroid gland and enlarged lymph nodes along the cervical vessels and in the mediastinum. The patient underwent total thyroidectomy and, at the same time, two lymph nodes were removed. Histological examination of the thyroid gland revealed papillary thyroid carcinoma (PTC), T1aN0M0, and histological examination of the lymph nodes showed non-caseating granulomatous inflammation. After further investigation, a diagnosis of sarcoidosis (SA) was made.

Coexistence of SA and PTC may yield a diagnostic challenge as both diseases might involve the lymph nodes of the neck. Furthermore, the case illustrates the importance of close follow-up of even moderate hypercalcaemia, since it may evolve into a hypercalcaemic crisis.

ObjectivesTo describe pediatric and adolescent patients undergoing functional septorhinoplasty and to analyze both subjective and objective outcomes.MethodsRetrospective review of prospective cohort study of patients ≤18 years old undergoing functional septorhinoplasty between 2013 and 2016 at a tertiary care center. Patient demographics, nasal exam, procedure, and pre- and postoperative nasal obstruction symptom evaluation (NOSE) score, EuroQOL 5-dimension (EQ5D), and peak nasal inspiratory flow (PNIF) scores were analyzed.Results39 patients, 48.7% male, mean age 15.9 years (range 7–18), with nasal obstruction underwent functional septorhinoplasty with mean follow up of 8.5 months. Patients reported a history of allergies (46.5%), nasal fracture (59.0%), and previous nasal surgery (25.6%). Most common exam findings included internal nasal valve narrowing (92.3%), superior/dorsal septal deviation (74.4%), external nasal valve narrowing (43.6%), caudal septal deviation (35.9%), and a narrow middle vault (33.3%). Septal cartilage grafts were placed in 79.5% of patients and PDS plate was used in 28.2%. Most common procedures included spreader grafts (84.6%), columellar strut graft (30.8%), and swinging door (23.1%). Of patients with both baseline and postoperative scores, at last follow up NOSE scores (SD) decreased from 59.0 (23.7) to 21.2 (8.8) (n = 26, p < 0.001), EQ5D VAS scores increased from 76.2 (17.7) to 85.8 (13.5), (n = 19, p = 0.056), and PNIF scores increased from 66.2 (25.3) to 90.8 (46) L/min, (n = 13, p < 0.01); all mean differences met the minimal clinically important difference for each score. 2 patients underwent revision surgery and there was one complication of a nasal abscess.ConclusionsFunctional septorhinoplasty is safe and effective in select pediatric and adolescent patients with significant nasal obstruction and results in significant improvements in both subjective and objective outcomes measures.

Clinical significance of spontaneous nystagmus in pediatric patients

Publication date: August 2018
Source:International Journal of Pediatric Otorhinolaryngology, Volume 111
Author(s): Guangwei Zhou, Cassandra Goutos, Sophie Lipson, Jacob Brodsky
ObjectiveTo analyze spontaneous nystagmus recorded in pediatric patients and determine its diagnostic value.Materials and methodsRetrospective review of 86 patients (mean age = 13.9 ± 4.7 years) with definitive spontaneous nystagmus recorded by videonystagmography (VNG). Spontaneous nystagmus was categorized and analyzed based on its characteristics. Correlations between spontaneous nystagmus and established clinical diagnoses were explored.ResultsAmong the patients seen in a period of three years at our pediatric vestibular clinic, 15.4% (86 out of 560) were found to have spontaneous nystagmus and half of them had horizontal nystagmus with a fixed-direction. The majority of cases with spontaneous nystagmus (77%, 66/86) were present without fixation only, while the presence of spontaneous nystagmus with and without fixation was found in 16 patients (19%). Most patients with spontaneous nystagmus without fixation only (68%) were diagnosed with a peripheral vestibular disorder (e.g., vestibular neuritis) or vestibular migraine. In contrast, vertical nystagmus was found in 15 patients, most of whom had central vestibular disorders. Other rare forms of nystagmus or abnormal eye movements, such as pendular nystagmus, ocular oscillation or flutter were recorded in only four patients.ConclusionsSpontaneous nystagmus in children and young adults with possible vestibular impairments may vary in clinical presentation. Identification of its characteristics may help to make an accurate clinical diagnosis. While spontaneous nystagmus associated with peripheral vestibular disorders can be readily recognized, spontaneous nystagmus in pediatric patients with vestibular migraine appears to be more complex and variable in form.

Diagnosis of COPD is based on meeting the physiologic criteria of fixed obstruction in forced expiratory flows and treatment focus on symptomatic relief, with limited effect on overall prognosis. However, patients with COPD have distinct features that determine very different evolutions of the disease. In this review we highlight distinct subgroups of COPD characterized by unique pathophysiologic derangements, response to treatment, and disease progression. It is likely that identification of subgroups of COPD will lead to discovery of much needed disease-modifying therapeutic approaches. We argue that a precision approach that integrates multiple dimensions (clinical, physiologic, imaging, and endotyping) is needed to move the field forward in the treatment of this disease.

Of pleiotropy and trajectories: Does the TGF-β pathway link childhood asthma and chronic obstructive pulmonary disease?

Publication date: June 2018
Source:Journal of Allergy and Clinical Immunology, Volume 141, Issue 6
Author(s): Avery DeVries, Donata Vercelli
The study of developmental trajectories is where epigenetics truly shines. The "epi" in epigenetics captures the fact that although epigenetic processes also preside over the maintenance and termination of gene expression, the unfolding and remodeling of chromatin architecture are especially critical to prepare genes for regulated transcription. These properties imply being on a path, a trajectory to events that will occur later thanks to epigenetic programming. Thus epigenetics is about timed and timely events. In this article we discuss epigenetic and genetic evidence from several independent studies of asthma, chronic obstructive pulmonary disease, and lung function, which converge to highlight a potential role of the TGF-β gene pathway in these processes. These results raise the possibility that at least in a subset of subjects, these conditions might be functionally connected in ways that need to be further defined but that likely reflect the uniquely pleiotropic nature of TGF-β pathway genes, particularly their ability to control both lung development and immune responses essential for regulation and inflammation. Further characterization of this pathway in longitudinally phenotyped populations might unmask novel trajectories to lung disease that begin in utero and unfold into old age.

BackgroundExacerbations of asthma and chronic obstructive pulmonary disease (COPD) are heterogeneous.ObjectiveWe sought to investigate the sputum cellular, mediator, and microbiome profiles of both asthma and COPD exacerbations.MethodsPatients with severe asthma or moderate-to-severe COPD were recruited prospectively to a single center. Sputum mediators were available in 32 asthmatic patients and 73 patients with COPD assessed at exacerbation. Biologic clusters were determined by using factor and cluster analyses on a panel of sputum mediators. Patterns of clinical parameters, sputum mediators, and microbiome communities were assessed across the identified clusters.ResultsThe asthmatic patients and patients with COPD had different clinical characteristics and inflammatory profiles but similar microbial ecology. Three exacerbation biologic clusters were identified. Cluster 1 was COPD predominant, with 27 patients with COPD and 7 asthmatic patients exhibiting increased blood and sputum neutrophil counts, proinflammatory mediators (IL-1β, IL-6, IL-6 receptor, TNF-α, TNF receptors 1 and 2, and vascular endothelial growth factor), and proportions of the bacterial phylum Proteobacteria. Cluster 2 had 10 asthmatic patients and 17 patients with COPD with increased blood and sputum eosinophil counts, type 2 mediators (IL-5, IL-13, CCL13, CCL17, and CCL26), and proportions of the bacterial phylum Bacteroidetes. Cluster 3 had 15 asthmatic patients and 29 patients with COPD with increased type 1 mediators (CXCL10, CXCL11, and IFN-γ) and proportions of the phyla Actinobacteria and Firmicutes.ConclusionsA biologic clustering approach revealed 3 subgroups of asthma and COPD exacerbations, each with different percentages of patients with overlapping asthma and COPD. The sputum mediator and microbiome profiles were distinct between clusters.

Blood eosinophil count thresholds and exacerbations in patients with chronic obstructive pulmonary disease

Publication date: June 2018

BackgroundEosinophilic airway inflammation in patients with chronic obstructive pulmonary disease (COPD) is associated with exacerbations and responsivity to steroids, suggesting potential shared mechanisms with eosinophilic asthma. However, there is no consistent blood eosinophil count that has been used to define the increased exacerbation risk.ObjectiveWe sought to investigate blood eosinophil counts associated with exacerbation risk in patients with COPD.MethodsBlood eosinophil counts and exacerbation risk were analyzed in patients with moderate-to-severe COPD by using 2 independent studies of former and current smokers with longitudinal data. The Genetic Epidemiology of COPD (COPDGene) study was analyzed for discovery (n = 1,553), and the Evaluation of COPD Longitudinally to Identify Predictive Surrogate Endpoints (ECLIPSE) study was analyzed for validation (n = 1,895). A subset of the ECLIPSE study subjects were used to assess the stability of blood eosinophil counts over time.ResultsCOPD exacerbation risk increased with higher eosinophil counts. An eosinophil count threshold of 300 cells/μL or greater showed adjusted incidence rate ratios for exacerbations of 1.32 in the COPDGene study (95% CI, 1.10-1.63). The cutoff of 300 cells/μL or greater was validated for prospective risk of exacerbation in the ECLIPSE study, with adjusted incidence rate ratios of 1.22 (95% CI, 1.06-1.41) using 3-year follow-up data. Stratified analysis confirmed that the increased exacerbation risk associated with an eosinophil count of 300 cells/μL or greater was driven by subjects with a history of frequent exacerbations in both the COPDGene and ECLIPSE studies.ConclusionsPatients with moderate-to-severe COPD and blood eosinophil counts of 300 cells/μL or greater had an increased risk exacerbations in the COPDGene study, which was prospectively validated in the ECLIPSE study.

Massive thrombus trapped within an atrial septal defect

Description 

A 39-year-old morbidly obese man with a medical history of tobacco abuse and paroxysmal atrial fibrillation (Afib) on rivaroxaban presented to the emergency department with acute onset of shortness of breath and severe pleuritic chest pain. His vital signs were significant for blood pressure of 100/60 mm Hg, heart rate of 110 per minute, respiratory rate of 30 per minute and oxygen saturation of 80% on a non-rebreather mask. Physical examination was unremarkable, except for increased work of breathing. Arterial blood gas (ABG) showed pH 7.49, Pa_CO2 30 mm Hg and Pa_O2 86 mm Hg. Laboratory tests were significant for elevated troponin at 2.35 ng/mL and B-type natriuretic peptide at 309 pg/mL. ECG showed sinus tachycardia with new onset incomplete right bundle block and T-wave inversion in the right precordial and the inferior leads (figure 1A).

Magnetic sphincter augmentation is an effective option for refractory duodeno-gastro-oesophageal reflux following Billroth II gastrectomy

Bile reflux into the gastric stump and then into the oesophagus is a common event after distal gastrectomy and Billroth II reconstruction. In addition to typical symptoms of nausea, epigastric pain and bile vomiting, acid reflux can also occur in patients with concomitant hiatus hernia and lower oesophageal sphincter incompetency. Diverting the bile away from the oesophagus by conversion into a Roux-en-Y anastomosis or by completion gastrectomy and Roux-en-Y esophagojejunostomy have so far represented the mainstay of treatment. We report the first case of magnetic sphincter augmentation to relieve refractory reflux symptoms after Billroth II gastrectomy. The procedure was performed through a laparoscopic approach and proved very effective at 1-year follow-up.

Big heart

Description

A 66-year-old female patient with a history of persistent atrial fibrillation and severe mitral stenosis secondary to rheumatic heart disease for which she underwent mitral valve replacement 25 years ago presented with progression of her baseline dyspnoea. On presentation, she had stable vital signs; neck examination revealed bilateral congested neck veins with prominent systolic venous pulsations. Chest and heart auscultation revealed a well-heard mechanical click, a pansystolic murmur heard over the tricuspid area and diminished air entry over the right lung base.

ECG revealed atrial fibrillation. Laboratory work-up showed that she was adequately anticoagulated but otherwise unremarkable; chest X-ray showed significant cardiomegaly, tracheal shift to the right and obliteration of the right basal lung field (figure 1).

Meningovascular syphilis causing recurrent stroke and diagnostic difficulties: a scourge from the past

We describe a case of a 49-year-old man who presented with recurrent strokes in the left middle cerebral artery territory, manifesting with dysphasia, higher cognitive deficits, motor deficits and subsequent infarcts in the right middle cerebral and anterior cerebral artery territories, manifesting with seizures, behavioural and social issues. A key issue of the case was the diagnostic difficulty faced by the physicians. 'Meningovascular syphilis' was subsequently confirmed and appropriate treatment was given but there was subsequent relapse with worsening of the symptoms. Multiple specialists were involved in the management, namely stroke team, neurologists, psychiatrists, infectious disease and multidisciplinary therapy teams. This case highlights the need to be vigilant to the resurgence of syphilis, a scourge from the past, as a cause of stroke, especially in individuals who have had exposure to affected people. It is easy to miss the diagnosis and mistake it for other conditions unless a detailed history is taken and appropriate investigations are conducted, with a low threshold for diagnosis.

Uterocutaneous fistula as the primary presentation of a gynaecological malignancy

We report a case of high-grade gynaecological carcinoma presenting as a uterocutaneous fistula. A 59-year-old woman presented with a discharging abdominal wall wound. Imaging confirmed a large solid pelvic mass forming a sinus tract with the anterior abdominal wall. The tract tunnelled through a previous caesarean section scar. Biopsy indicated a high-grade gynaecological carcinoma, with features suggestive of endometrioid adenocarcinoma. The patient underwent two cycles of chemotherapy. Despite this, the mass increased in size and was complicated by abdominal wall wound breakdown. Chemotherapy was ceased. Surgical and palliative options are under consideration.

Dangerous mistake: an accidental caffeine overdose

Caffeine (1,3,7-trimethylxanthine) is a natural product commonly presented in food's composition, beverages and medicinal products. Generally, it is thought to be safe under normal dosage, yet it can be fatal in case of severe intoxication. We report a case of a healthy 32-year-old woman who went to the local emergency department (ED) 30 min after ingesting, accidentally, 5000 mg of anhydrous caffeine for a preworkout supplement. At the ED, she presented an episode of presyncope followed by agitation. ECG showed polymorphic broad complex QRS tachycardia and arterial blood gas revealed metabolic acidaemia with severe hypokalemia. The dysrhythmia was successfully treated with intravenous propranolol. Acid–base and hydroelectrolytic disorders were also corrected. A persistent sinus tachycardia was observed in the first 2 days in the ward and 5 days later she was discharged asymptomatic with internal medicine follow-up.

Gallbladder volvulus with segmental right liver lobe hypoplasia/atrophy: a preoperative diagnostic dilemma

Gallbladder volvulus (GBV) due to rotation of the gall bladder (GB) around its own mesentery is a rare surgical emergency and often identified intraoperatively. Typically, cholecystitis is the initial clinical diagnosis, but a high index of suspicion on imaging can alert the physician for the possibility of GBV requiring urgent surgical intervention. We describe a case of a young female patient with hypoplasia/atrophy of the posterior segment of the right liver lobe and a GB with no hepatic attachments but only mesenteric pedicle. She presented with first episode of sudden-onset, severe right subcostal pain. The ultrasonogram and magnetic resonance cholangiopancreatogram findings were suggestive of GBV. She underwent laparoscopic exploration that confirmed GBV of a free-floating GB with a thrombosed cystic artery. The GB was detorted, and cholecystectomy was performed. She had an uneventful postoperative course and was discharged with no complications. Histopathological examination showed intramural haematoma of the GB with wall necrosis.

Systolic heart failure in a patient with primary aldosteronism

A 53-year-old African man with a 25-year history of uncontrolled hypertension and systolic heart failure presented with an acute congestive heart failure exacerbation. He was found to have severe hypokalaemia, so additional testing was performed, and primary aldosteronism was confirmed. CT scan showed a 1.2x2.4 cm well-defined, homogeneous adenoma of the left adrenal gland. Adrenal vein sampling confirmed unilateral primary aldosteronism with lateralisation to the left adrenal gland. The patient was started on spironolactone and was referred to surgery for laparoscopic left adrenalectomy. Primary aldosteronism is associated with high cardiovascular morbidity and mortality due to activation of cardiac mineralocorticoid receptors. Studies suggest these negative effects can be reduced with early intervention and treatment. This case highlights the importance of investigating secondary causes of hypertension in young patients and the potential adverse cardiac effects of primary aldosteronism when it goes undiagnosed and untreated for years.

Neuropsychological assessment as an objective tool to monitor treatment response in anti-N-methyl-D-aspartate receptor encephalitis

We report a 1-year follow-up of a young woman with anti-N-methyl-D-aspartate receptor encephalitis. Management of autoimmune encephalitis remains challenging as objective and clinically relevant biomarkers are sought, which allow for the monitoring of treatment response. While further investigation is required, we believe that this case highlights the importance of following a comprehensive neuropsychological profile as a clinically relevant biomarker to guide therapeutic decision-making. By relying on the neuropsychological assessment of the patient, treatment with more toxic medications was avoided and her antiepileptic drug regimen was simplified.

Alimentary tract duplications are a rare congenital malformation. They can present with varied symptoms owing to the locality of the duplication, along the gastrointestinal tract. Out of these duplications, the ones along the pylorus are the most rare. These are usually only diagnosed intraoperatively, as it is not a common differential on imaging due to its rarity. In lieu of the literature currently available, pyloric duplication cyst can present anytime from 1 week of age to 5 years, with some cases being detected antenatally due to the prevalence of regular antenatal scanning. Surgery remains the main stay of treatment with the goal of complete excision of the cyst and complete removal of the cyst mucosal lining. We report the case of a 5-year-old girl, which to our knowledge is the first ever reported case from Karachi, Pakistan.

Phaeochromocytoma found on cardiovascular magnetic resonance in a patient presenting with acute myocarditis: an unusual association

Myocarditis is inflammation of the cardiac muscle. The symptoms, signs and basic investigation findings can mimic that of myocardial infarction. The most common cause is infection (most commonly viral). Cardiovascular magnetic resonance (CMR) is the gold standard non-invasive diagnostic test for potential acute myocarditis as it allows assessment of myocardial oedema and scar. A man aged 25 years was admitted with chest pain, dizziness, headache, palpitations and sweating. His troponin was mildly positive. A CMR was performed which showed mild myocarditis and a right suprarenal mass which was confirmed to be a phaeochromocytoma based on biochemistry and a dedicated imaging workup. Phaeochromocytoma can lead to cardiac involvement in the form of left ventricular dysfunction, or catecholamine-induced myocarditis.

IntroductionLa consommation régulière de cannabis peut s'associer à certaines toxicités endobuccales, souvent mal connues du clinicien : xérostomie, caries, maladie parodontale, leucoedème, hyperplasie gingivale, colonisation à Candida albicans, leucoplasie ou gingivite…ObservationNous rapportons ici l'apparition d'une coloration verte de la langue chez un patient, consécutive à l'inhalation intensive de marijuana.DiscussionCette complication n'a qu'exceptionnellement été rapportée dans la littérature médicale. Paradoxalement, elle est clairement identifiée sur différents moteurs de recherche sur internet, notamment Google.BackgroundRegular cannabis use may be associated with several oral changes not usually identified by dermatologists: xerostomia, increased risk of caries, periodontitis, leukoedema, gingival hyperplasia, and higher prevalence and density of Candida albicans, leukoplakia or gingivitis.Patients and methodsWe report herein the appearance of a characteristic green tongue in a patient following intensive marijuana inhalation.DiscussionThis complication has rarely been reported in the medical literature. Paradoxically, it is clearly described in different Internet search engines, particularly Google.

Lymphome T cutané et systémique traité avec succès par greffe haplo-identique

IntroductionNous rapportons un cas de lymphome T cutané et systémique ayant résisté au traitement conventionnel et dont l'évolution a conduit à réaliser une greffe de moelle haplo-identique.ObservationUne femme de 53 ans consultait pour un érythème infiltré du visage, des lésions kératosiques du tronc et des adénopathies centimétriques axillaires et inguinales. Le diagnostic de syndrome de Sézary (SS), forme leucémique d'un lymphome T cutané épidermotrope, était retenu. Après 3 ans de traitement par méthotrexate, la patiente développait un SS transformé avec atteinte viscérale. Le fort risque de rechute et l'absence de donneur HLA-compatible amenait à la réalisation d'une greffe haplo-identique de moelle osseuse. La patiente était en rémission complète à 2 ans et demi. L'évolution était cependant marquée par l'apparition, un an après la greffe, d'une éruption lichénoïde blaschko-distribuée dont l'aspect histologique était compatible avec une réaction du greffon contre l'hôte (GVH) chronique ; elle était traitée efficacement par bétaméthasone topique.DiscussionNous rapportons, à notre connaissance, la première greffe haplo-identique réalisée pour un lymphome cutané T transformé et systémique. Ce traitement pourrait désormais être une option pour les patients nécessitant une allogreffe mais n'ayant pas de donneur compatible. Les lésions lichénoïdes blaschko-distribuées attribuées à une GVH chronique pourraient être la conséquence d'une perte d'immunotolérance vis-à-vis de clones embryologiques anormaux, provoquant ainsi une réaction inflammatoire médiée par les lymphocytes T.BackgroundHerein, we report a case of systemic cutaneous T-cell lymphoma refractory to standard therapy, the course of which resulted in haplo-identical bone marrow grafting.Patients and methodsA 53-year-old woman consulted for facial erythema with infiltration, keratotic lesions on the trunk, and adenopathies measuring around 1cm on the axilla and inguinal folds. A diagnosis was made of Sézary syndrome (SS), a leukaemic form of epidermotropic cutaneous T-cell lymphoma. After three years of treatment with methotrexate, the patient developed transformed SS with visceral involvement. Given the high risk of relapse and the absence of an HLA-compatible donor, haploidentical bone marrow grafting was performed. The patient was still in complete remission two and a half years later. The disease course was nevertheless marked by the emergence one year after grafting of a Blaschko-distributed lichenoid eruption having histological features consistent with chronic graft-versus-host disease (GVHD); treatment with topical betamethasone proved efficacious.DiscussionTo our knowledge, this is the first reported case of haploidentical grafting for systemic and transformed cutaneous T-cell lymphoma. This approach could henceforth represent a therapeutic option for patients requiring an allograft in the absence of compatible donors. The Blaschko-distributed lichenoid lesions attributed to chronic GVHD could be the result of reduced immune tolerance to abnormal embryological clones leading to a T-lymphocyte-mediated inflammatory reaction.

A mixed methods examination of distress and person-centred experience of head and neck lymphoedema

Publication date: August 2018

Author(s): Jodie L. Nixon, Amanda E. Pigott, Bena Cartmill, Jane Turner, Jennifer Fleming, Sandro V. Porceddu
PurposeThis study aimed to examine the course and nature of distress and quality of life (QoL) during and after head and neck lymphoedema (HNL) treatment in people who developed HNL following treatment for head and neck cancer (HNC).MethodsThis study (n = 10) used a mixed method explanatory design to explore distress associated with HNL. Component 1 used a prospective repeated measures design to examine distress during a 22-week HNL program. Component 2 used a qualitative interview approach to understand the patient experience of distress after completion of HNL treatment.ResultsDuring the HNL program distress associated with HNL significantly reduced from baseline to week 6 (p = 0.015), and baseline to week 22 (p = 0.007). There were no significant differences in QoL, body image or fear of cancer progression over time. Self-reported presence of HNL significantly reduced from baseline to week 6 (p = 0.02), week 6 to week 22 (p = 0.026), and from baseline to week 22 (p = 0.001).Qualitative interviews using thematic analysis following HNL treatment, revealed 6 major themes associated with the experiences of distress related to HNL – psychological impact; physical appearance and pattern/timing; experience of receiving treatment; day to day impact; supports that helped manage distress; and adjustment to a new normal.ConclusionsThis study found that distress associated with cancer treatment-related HNL may reduce with the delivery of a HNL program. Interview data following completion of the HNL treatment identified several themes related to HNL and its relationship with distress, function and day-to-day life.Clinical Trial registration: HREC/12/QPAH/295.
