BackgroundThe transition from adolescence to young adulthood marks a developmental period in which responsibility for management of chronic conditions such as food allergy shifts from the caregiver to the young adult. Fatal food-induced anaphylaxis is most common among adolescents and young adults. However, colleges are currently not well positioned to provide integrated support for students with food allergies.ObjectiveThe study objective was to explore the systems, structures, and policies that currently support students with food allergies at college, assess unmet needs, and develop pilot interventions through the use of patient-centered design processes.MethodsKey informant interviews were conducted with stakeholders in the campus management of food allergies (n = 26) between April and May 2016. Data were coded and assessed for relative frequencies of each code to determine challenges and potential solutions.ResultsThe convergence of stakeholder-identified themes indicated that the transition to college for students with food allergy would be improved by providing support for: (1) Notification of others in the student's campus network about food allergy; (2) Establishing clearly defined roles/responsibilities; and (3) Increasing campus awareness of food allergy signs, symptoms, and lethality. To better provide comprehensive support for students, 5 interventions—collectively called Spotlight—were developed.ConclusionThe use of qualitative research methods, patient-centered design processes, and collaborations with diverse stakeholders—including pediatricians that care for adolescents—can provide a framework for designing coordinated systems and policies to provide comprehensive support to college students with food allergy. Next steps include rigorously testing implementation of the Spotlight intervention prototypes.

Onychomycosis is a fungal nail infection caused by dermatophytes, non-dermatophytes, and yeast and is the most common nail disorder seen in clinical practice. It is an important problem, as it may cause local pain, paresthesias, difficulties performing activities of daily life, and impair social interactions. In the following continuing medical education manuscript, we review the epidemiology, risk factors, and clinical presentation of onychomycosis and demonstrate current and emerging diagnostic strategies.

It is an important problem, as it may cause local pain, paresthesias, difficulties performing activities of daily life, and impair social interactions. The epidemiology, risk factors, and clinical presentation and diagnosis of onychomycosis were discussed in the first article in this continuing medical education series. In this article, we review the prognosis and response to onychomycosis treatment, Food and Drug Administration approved medications for onychomycosis, as well as, off-label therapies and devices.

The intestinal immune system is challenged daily with the task of recognizing and eliminating pathogens while simultaneously tolerating dietary and commensal antigens. All components must effectively coordinate to differentiate a continual barrage of environmental cues and mount appropriate responses dependent on the nature of the stimuli encountered. Playing a pivotal role, the aryl hydrocarbon receptor (AHR) is a chemical sensor that detects both dietary and microbial cues and is important for development, maintenance, and function of several types of intestinal immune cells, particularly innate lymphoid cells (ILCs) and T cells. In this review, we will highlight recent advances in our knowledge of the role of AHR signaling in ILCs, T cells, B cells, and dendritic cells.

Food allergy is an increasing public health problem, particularly in developed nations. This article discusses the nature of food allergy, the risk management strategies adopted by regulators and the need for allergen analysis. An overview is given of the different approaches to allergen analysis currently adopted. The article concentrates on enzyme linked immunosorbent assay, ELISA, since this is currently the technique most applied in routine allergen analysis. The history and main formats (sandwich and direct ELISAs) are described along with practical advice on extraction, validation and reporting results. Research proteomics, polymerase chain reaction for amplification and detection of allergen species DNA and liquid chromatography-mass spectrometry approaches are described.

Brown-Vialetto-Van Laere syndrome (BVVLS) or riboflavin transporter deficiency (OMIM 211530) is a rare treatable autosomal recessive neurodegenerative disorder. This condition is associated with progressive pontobulbar palsy. We describe the clinical course of a 16-month-old boy with BVVLS and a novel homozygous mutation from Pakistan. Our patient presented with stridor and respiratory insufficiency. Hearing loss which is the most common sign of this condition was absent, making it an unusual presentation of BVVLS. His examination revealed ptosis and tongue fasciculation. His riboflavin receptor mutational analysis showed the homozygous mutation in the SLC52A3 gene. Per oral riboflavin was administered, and subsequently, he was able to be weaned off the ventilator. Now the child is improving and attaining developmental milestones.
An 80-year-old man presented repeatedly to his general practitioner with 3 months of unexplained persistent frontal headaches. CT head revealed no diagnosis. His dentist diagnosed his co-existing jaw pain as bruxism. Three months later, the patient happened to attend a routine ophthalmology follow-up appointment. During this routine appointment, features of giant cell arteritis (GCA) including worrying visual complications were first noted. His inflammatory markers (C-reactive protein and erythrocyte sedimentation rate) were not significantly raised—contrary to the norm. A temporal artery ultrasound and biopsy were performed, in light of the history. This confirmed GCA. He was commenced on high-dose oral prednisolone and was managed by ophthalmology and rheumatology. At 4 weeks, symptoms resolved with no permanent visual loss despite a prolonged initial symptomatic period. Multiple symptomatic presentations to different specialties should therefore alert clinicians to a unifying diagnosis, for example, vasculitis. Serious illnesses may present with severe symptoms despite normal screening investigations.
Surgery in the neonatal period presents challenges, especially in preterm infants weighing <1 kg. Their small size, minimal reserves and physiological immaturity means attention to detail and careful monitoring is critical to avoid cardiovascular instability; maintaining fluid balance and metabolic stability is also problematic due to often limited vascular access and small blood volumes. Developments in technology have meant that cardiovascular parameters such as heart rate, blood pressure and oxygen saturations are all routinely and continuously monitored before and during surgery.
We have been exploring the role of continuous glucose monitoring (CGM) for metabolic monitoring and management of glucose control in very preterm infants (24–32 weeks gestation). In this paper, we report on a preterm infant who uniquely underwent surgery while wearing a continuous glucose monitor, blinded to the clinical team. This case highlights the metabolic vulnerability of these babies and a possible role for real-time CGM during surgical procedures.
This paper describes a patient who presented with mania with psychotic features in the context of concomitant use of S-adenosyl-L-methionine (SAMe) and selective serotonin reuptake inhibitor (SSRI). The aim of this case report is to provide medical practitioners with a greater awareness of the possibility of a psychotic episode and/or mania manifesting with concurrent use of SAMe and SSRI.

In the 'Summary' and 'Discussion' sections, it is stated that 36 previous cases have been reported, while in fact this number is incorrect: the correct number of cases that have been previously reported is 15.
A 30-year-old woman with severe dengue presented on the sixth day of her illness with life-threatening thrombocytopenia, refractory to multiple platelet transfusions. Dengue IgM antibody and the non-structural-1 antigen tests as of day 3 were negative. The IgG antibody against the same was positive, suggesting a past episode of dengue. Since she had a history of menorrhagia prior to the current illness, a working diagnosis of idiopathic thrombocytopenic purpura was made, for which intravenous immunoglobulin (IVIg) was administered that led to a rapid rise in the platelet count with no adverse events. Subsequently, dengue IgM antibody repeated on day 6 came back positive, confirming dengue. This case report re-emphasises the potential use of IVIg in patients with severe thrombocytopenia in dengue.
A 72-year-old Chinese man presented with mild symptoms of heart failure. Transthoracic echocardiography showed signs of cardiac tamponade though clinically he was relatively well. The option of pericardiocentesis was not carried out due to a narrow window for aspiration with only a thin layer of effusion seen surrounding the apex and right ventricle on subcostal view.
Pericardial window was done via a left anterolateral thoracotomy. Intraoperatively, 500 cm3 of purulent fluid was drained. Microbiology screens were all negative. We present the atypical clinical course of this elderly man presenting with a large pyopericardium.
A 25-year-old male patient presented with complaints of blurred vision in both eyes since 2 years. The patient was a known case of nephrotic syndrome with dyslipidaemia for which he was on diuretics and lipid-lowering agents for 3 years. On examination, his visual acuity was 6/9 in both eyes with cloudy cornea and arcus juvenilis. Fundus examination was within normal limits. On systemic work-up, his lipid profile was deranged with increased serum total cholesterol, very low density lipoprotein, low density lipoprotein and triglyceride. The serum high density lipoprotein was decreased. Renal function test revealed elevated serum creatinine with significant proteinuria. Renal biopsy was suggestive of dense deposit disease on immunofluorescence and transmission electron microscopy. Ocular manifestation of dense deposit disease is characterised by retinal drusen, pigmentary atrophy, choroidal neovascular membrane and atypical serous retinopathy. To the best of our knowledge, anterior segment changes in dense deposit disease has not been reported. This is the first case reporting cloudy cornea with arcus juvenilis in a case of dense deposit disease.

A 26-year-old man with premorbid cutaneous neurofibromatosis presented with history of insidious onset, slowly progressive, bilaterally asymmetrical quadriparesis along with incontinence of urine since 4 weeks. Simultaneous to the onset of motor symptoms, he also complained of paraesthesias in all four limbs. On examination, multiple cutaneous neurofibromas were noticed all over his trunk, abdomen and all the limbs (figure 1). The upper and lower limbs were spastic. Motor power as per Medical Research Council grading was 3/5 in all four limbs. The deep tendon reflexes were brisk. The plantar response on both sides was extensor. The sensory level was clinically around C3/C4 dermatome.

A dural arteriovenous fistula (DAVF) presenting with acute subdural haematoma (ASDH), which were not related to head injury, is rare. A 61-year-old woman was transported by ambulance because of deterioration of consciousness. On admission, she was comatose with anisocoria. Emergent CT demonstrated a severe midline shift associated with a left ASDH and an additional left occipital intracerebral haematoma, both of which had no continuity with each other. MRI showed flow void signs in the left occipital lobe. Because of the impending cerebral herniation, an emergent evacuation of the ASDH and external decompression was performed. Subsequent evaluation revealed a DAVF at the left occipital convexity near the confluence with retrograde leptomeningeal venous reflux and venous ectasia (Cognard type III DAVF). The patient underwent endovascular treatment for the DAVF involving transarterial embolisation using coils and N-butyl cyanoacrylate with complete obliteration. Her further clinical course was uneventful and discharged after cranioplasty.

The allergic (or atopic) march refers to the natural history of allergic diseases as they develop during infancy and childhood. The march conventionally begins with atopic dermatitis (AD) and progresses to IgE-mediated food allergy (IgE-FA), asthma, and allergic rhinitis (AR).1 The observation that allergic manifestations tend to develop in this stereotyped progression stems from decades of observational research, including birth cohort studies. It has also been the basis for large, longitudinal studies of individual disease associations.

A woman in her 30s with medical history notable for hypothyroidism due to Hashimoto's thyroiditis had a brain MRI ordered by her neurologist due to change in chronic headache pattern. This had an incidental finding of enlarged pituitary gland. She was referred at that time to an endocrinologist but was not seen. Eighteen months later, she presented with worsening headaches, blurry vision, weight gain and galactorrhoea. Repeat brain MRI showed a 9x10x13 mm sellar mass extending superiorly, with mass effect on optic chiasm (figure 1A). Thyroid-stimulating hormone (TSH) was 185 mIU/mL with low free T3, low free T4, normal prolactin, normal FSH and normal LH. She was then referred to a neurosurgeon and an ophthalmologist. Visual field testing initially showed mild constriction of bilateral visual fields. The neurosurgeon referred her to an endocrinologist for preoperative hormonal evaluation, but the operation date was advanced when subjective visual...
Description
A young man was admitted to the emergency department after consuming zinc phosphide, with severe drug refractory hypotension. ECG (refer figure 1) revealed ST segment elevation involving anterior, lateral and inferior leads. Serum levels of potassium, calcium, magnesium and phosphorous were normal; serum troponin-T was 1126 ng/nL (upper limit of normal 14 ng/nL), with associated metabolic acidosis. Echocardiogram revealed severe left ventricular systolic dysfunction. Severe myocardial depression with histopathological evidence of myocyte vacuolation and myocytolysis has been occasionally described with aluminium phosphide toxicity, primarily mediated by phosphine. The absence of an antidote makes the mortality high, once refractory shock ensues. Our patient succumbed to this condition. Zinc phosphide toxicity mediated by phosphine can have similar multisystem involvement, though dramatic electrocardiographic changes are uncommon.1 2 However, as evidenced by our report, ST segment elevation involving multiple leads on the ECG, though rare, maybe a hazardous manifestation...
Foreign body ingestion is a common event; in the adult population, most ingestions occur in patients with mental disability, psychiatric disorders, alcohol intoxication or in prisoners seeking secondary gain. Removal through flexible endoscopy is generally the first-line approach but rescue oesophagotomy may be necessary for foreign bodies impacted in the upper oesophagus. A 27-year-old man was admitted in the emergency room after intentional ingestion of a wooden spherical object with a central hole. A total body CT scan showed that the object was completely obstructing the upper oesophageal lumen but there were no signs of perforation. In the operating room, a Weerda diverticuloscope and a 5 mm 0° telescope were used to visualise the foreign body under general anaesthesia. A standard endoscopic biopsy forceps was passed through the hole of the sphere and was retracted with the jaws open allowing transoral extraction without complications.
This is a reminder of a rare cause of osteoporosis that remains widely underdiagnosed and lacks specific evidence on its optimal management. We bring a case report of a patient presenting with erectile dysfunction and high testosterone level but also elevated sex-hormone binding globulin hence low free androgen index as well as evidence of organ specific hypogonadal side effects such as osteoporosis. A unifying diagnosis of alpha-1 antitrypsin deficiency (AATD) brought together his coexistent mild chronic obstructive pulmonary disease as well as a new finding of previously unrecognised liver disease. This case highlights the uncertainties over the mechanism of osteoporosis in AATD as well as the controversies over best way to manage it. The efficacy of testosterone replacement in managing osteoporosis in the context of AATD remains untested. National registries for AATD would be best placed at gathering further evidence in this area.

A 35-year-old Caucasian woman was referred by a general practitioner to our medical ward because she was suffering from recurrent arthralgia, urticarial rash with mild pruritus and cervical lymph nodes. There was no sign of arthritis, any fever, chills or night sweats, but she had lost 2.5 kg in 3 months. The average lengths of symptoms were more than 6 weeks.
She presented the same symptoms with cervical lymph nodes when she was 24 years old. She received doxycycline for a suspicion of Lyme disease and the evolution was favourable after 2 weeks of treatment. However, serology was not compatible with recent Lyme disease. Since then, the frequencies of the attacks were rare but occurred once a year.
The routine blood tests were normal except a slightly elevated C reactive protein at 12 mg/L (normal value <5 mg/L). Infectious serologies for Cytomegalovirus, Epstein-Barr virus, HIV, hepatitis C and B, Brucella, Bartonella henselae and...
Up to 20% of hospitalised patients may have low serum phosphate concentrations. In certain groups, such as patients with chronic alcohol overconsumption, severe trauma or sepsis, the prevalence may be 30%–50%. Profound hypophosphataemia is less common, but may lead to severe physiological disturbances. In rare cases, hypophosphataemia is caused by phosphaturic substances excreted from a tumour. Osteomalacia with chronic bone pain and fractures, as well as muscle weakness, is common in such patients. The tumours are often small and difficult to detect. Studies suggest that fibroblast growth factor 23 is a reliable marker for detection of these tumours. Persistent hypophosphatemia unresponsive to supplements should raise clinical alertness. With complete resection of the neoplasm, the symptoms rapidly reverse. If the tumour cannot be removed, treatment relies on supplementation with phosphate and active vitamin D compounds. We present a case report of a patient with severe hypophosphataemia, osteomalacia, dysphagia and malnutrition.
This is the case of a 56-year-old white woman with a medical history significant for chronic obstructive pulmonary disease, migraine, hypertension, tobacco abuse and hypercholesterolaemia. Her surgical history is significant for total hysterectomy and bilateral salpingo-oophorectomy for diffuse endometriosis. The patient presented with a vaginal lesion. The biopsy was positive for primary vaginal small cell carcinoma and human papilloma virus (HPV). Initial staging positron emission tomography (PET) scan confirmed stage 1 disease. The patient was started on chemotherapy with cisplatin and etoposide for four cycles, followed by concurrent chemotherapy with cisplatin/taxol and radiation therapy.
Hallucinations, visual, auditory or in another sensory modality, often respond well to treatment in patients with schizophrenia. Some, however, do not and can be very chronic and debilitating. We present a patient with schizophrenia with intractable hallucinations despite state of the art care, including high-dose clozapine and transcranial magnetic stimulation. Based on the possible role of the 5-HT2A receptor in hallucinations, we treated her with the antihypertensive drug ketanserin, a 5-HT2A receptor antagonist.
This significantly reduced her visual but not her auditory hallucinations, suggesting a possible role of the 5HT2A receptor in the pathophysiology of specifically visual hallucinations. This is the first time ketanserin has been described to successfully reduce visual hallucinations in a patient with schizophrenia.

Indocyanine green (ICG) is a water-soluble, non-toxic tricarbocyanine dye extracted exclusively from the hepatic parenchyma. Measurement of ICG clearance using pulse spectrophotometry is a simple, reproducible and non-invasive test, easily performed in the operating room. ICG plasma disappearance rate (PDR) and the retention rate at 15 min (R15) produce real-time metrics to aid assessment and decision-making before, during and after complex liver surgery. ICG clearance has also been used to suggest the presence of postoperative complications, including thrombosis of the hepatic artery and graft dysfunction following liver transplantation. We present a case of 65-year-old Caucasian man, with Child-Pugh A liver cirrhosis undergoing complex right hepatectomy for metastatic colorectal liver cancer where ICG clearance impacted on the extent of surgical resection.
Given the concerns about marginal postoperative liver function of the residual left hepatic lobe, we used pulse spectrometry intraoperatively to predict the risk of postoperative liver dysfunction. Immediately preoperatively, a...
Pseudoaneurysms adjacent to exostoses have been commonly reported in the femoral and popliteal arteries and only rarely in the upper extremity. We describe a case of an 18-year-old man with multiple hereditary exostoses who developed a brachial artery pseudoaneurysm after minor trauma to his right upper arm, adjacent to a known lesion. He was referred to a vascular surgeon who removed the pseudoaneurysm and repaired the artery with a saphenous vein graft. We encourage a high suspicion of vascular injury even after minor trauma when an osteochondroma is adjacent to a vascular structure.
A 69-year-old man was admitted with non-resolving right leg cellulitis. Subsequent skin changes over the calf and discharging pus suggested necrotising fasciitis. After several wound debridements of the leg and imaging, the patient was found to have an iliopsoas abscess due to a metastatic perforated caecal tumour extending along the medial thigh to the calf. No micro-organisms indicative of typical necrotising fasciitis were isolated from the wound. The patient had an ileocaecal resection, and his leg was reconstructed with a split thickness skin graft. He continues to do well postoperatively. This case highlights key lessons when dealing with an unusual presentation leading to challenges in diagnosis such as: (1) the need for good interspecialty liaison, (2) prompt senior review and plan, and (3) 'thinking outside the box' when faced with a diagnostic challenge.
Prosthetic joint infection due to Salmonella spp is rare. Here we report an acute case of Salmonella enteritidis infection of a total hip arthroplasty in a man taking immunosuppressant medication. He was managed with antibiotics and two-stage revision surgery.
Steroid-induced ocular hypertension (SIOH) is a challenging entity in paediatric age, with many being refractory to medical therapy. Literature is scarce about surgical options in these cases. A 14-year-old girl with bilateral uveitis and macular oedema had received an intravitreal and subconjunctival triamcinolone injection in the right (OD) and left (OS) eye, respectively. While the steroid was effective in resolving the oedema, intraocular pressure (IOP) increased to about 40 mm Hg OD and 34 mm Hg OS, despite being under maximal IOP-lowering therapy. An initial conservative approach was preferred due to the young patient age and given that most cases of SIOH are transient. However, progressive structural changes were documented, and bilateral sequential minimally invasive glaucoma surgery (MIGS: XEN gel stent) was taken. With a follow-up of 6 months, the patient is drug-free with IOP around 14 mm Hg. This report discusses the role and efficacy of MIGS in a paediatric case of SIOH.
We describe a case report of a 53-year-old man with a 5-months history of progressive jaundice and upper abdominal pain. The patient was further evaluated and finally diagnosed with a high-grade ampullary neuroendocrine tumour (based on endoscopic-guided biopsy). Thereafter, he underwent pancreatoduodenectomy and adjuvant platinum-based chemotherapy. This extremely rare case presents his long-lasting disease-free survival compared with similar cases; this case report exemplifies a new, potentially efficient method for treating high-grade papillary neuroendocrine tumour and may pave the way for further clinical trials utilising this blueprint in the treatment of related conditions.
Solid pseudopapillary neoplasm of the pancreas is a rare condition. It is mostly seen among young women, with abdominal pain as the presenting complaint. This is a case of a young woman who presented with haematochezia, and was found to have splenic vein thrombosis and left-sided portal hypertension as a result of mass lesion at the tail of the pancreas which was diagnosed as solid pseudopapillary neoplasm.
Arachnoid granulations are common incidentally detected small dural lesions which are usually asymptomatic and follow cerebrospinal fluid density/signal intensity on CT/MRI. Such lesions reaching a size of more than 1 cm are termed as giant arachnoid granulations (GAGs) which have been previously reported to cause venous hypertension and headaches. We report a case of GAG involving the proximal half of the superior sagittal sinus in a 45-year-old male patient which was associated with left temporal thrombosed dural arteriovenous fistula (AVF) whose thrombosed draining veins were seen converging towards the site of GAG. The patient presented with three episodes of generalised tonic-clonic seizures and improved with conservative treatment. No reports of such association of GAG with AVF is available in the literature, and we believe it could have occurred due to venous hypertension induced by GAG.
Description
A 5-year-old boy presented to the emergency department with intense dull aching pain in the left lower abdomen. On physical examination, his vitals were stable. A well-defined, tender, firm, 10x6 cm sized mass was palpable in the left lower abdomen occupying the left hypochondrium, left lumbar and umbilical regions. Urgent ultrasound revealed the absence of spleen in the normal position with a hypoechoic encapsulated mass in the left lower abdomen while Doppler study showed the absence of internal vascularity in it. Contrast-enhanced CT (CECT) of the abdomen (figure 1A,B) confirmed the presence of an enlarged, minimally enhancing and inferiorly displaced spleen with characteristic 'whirled appearance' of the splenic hilum. The diagnosis of splenic torsion was confirmed and an exploratory laparotomy was performed. Intraoperatively, the spleen was torsed 720 degrees on its pedicle with an engorged and thrombosed splenic vein (figure 2A,B). The ligamentous attachments (gastrosplenic, splenocolic,...
We report a rare case of ciliary body metastasis from adenocarcinoma of the lung. Although the metastatic nodule was seen over the surface of the iris near the angle of anterior chamber, ultrasonography confirmed its origin from the ciliary body. Uveal metastasis may be the first sign of lung cancer.
Spontaneous bilateral perirenal haematoma, as well as splenic haematoma, are rare occasions in polyarteritis nodosa (PAN). We report a case of a young man, who suffered from various typical and atypical manifestations of PAN since childhood. The diagnosis was delayed due to symptoms mimicking with other clinical conditions. Finally, the diagnosis was confirmed when presented with perirenal and splenic haematoma and was managed successfully.
Non-arteritic anterior ischaemic optic neuropathy (NAION) may develop due to severe anaemia and hypotension which is seen in acute blood loss. The devastating visual loss is often irreversible. We report a case of NAION in a 20-year-old healthy woman, who presented on the third day of a heavy menstrual cycle with hypovolaemic shock. On day 2 of admission, she had sudden right eye blurring of vision at the superior field on awakening from sleep. Funduscopy revealed a pale and swollen right optic disc. There was a dense right superior altitudinal visual field defect. Her haemoglobin level was low (3.6 g/dL), but she refused blood transfusion due to her religious belief (Jehovah's Witness) and opted for conservative management. She later developed right optic atrophy with persistent visual field defect despite an improved haemoglobin level of 10.5 g/dL.
