Progression of ductal carcinoma in situ to invasive breast cancer: comparative genomic sequencing

Abstract

Several models have been described as potential mechanisms for the progression of ductal carcinoma in situ (DCIS) to invasive breast cancer (IBC). The aim of our study was to increase our understanding of DCIS progression by using massive parallel sequencing of synchronous DCIS and IBC. We included patients with synchronous DCIS and IBC (n = 4). Initially, IBC and normal tissue were subjected to whole exome sequencing. Subsequently, targeted sequencing was performed to validate those tumor-specific variants identified by whole exome sequencing. Finally, we analyzed whether those specific variants of the invasive component were also present in the DCIS component. There was a high genomic concordance between synchronous DCIS and IBC (52 out of 92 mutations were present in both components). However, the remaining mutations (40 out of 92) were restricted to the invasive component. The proportion of tumor cells with these mutations was higher in the invasive component compared to the DCIS component in a subset of patients. Our findings support the theory that the progression from DCIS to IBC could be driven by the selection of subclones with specific genetic aberrations. This knowledge improves our understanding of DCIS progression, which may lead to the identification of potential markers of progression and novel therapeutic targets in order to develop a more personalized treatment of patients with DCIS.

Comparison of a novel clinical score to estimate the risk of REsidual neuromuscular block Prediction Score and the last train-of-four count documented in the electronic anaesthesia record: A retrospective cohort study of electronic data on file

BACKGROUND Residual neuromuscular block (rNMB) after surgery is not difficult to identify if proper neuromuscular monitoring is used, but many clinicians do not use quantitative neuromuscular monitoring. OBJECTIVE The aim of this study was to develop a REsidual neuromuscular block Prediction Score (REPS) to predict postoperative rNMB and compare the predictive accuracy of the prediction score with train-of-four count (TOFC) measurement at the end of a surgical case. DESIGN Retrospective cohort study of data on file. DATA SOURCE Electronic patient data and peri-operative data on vital signs, administered medications, and train-of-four ratio (TOFR) obtained in the postoperative recovery rooms [postanaesthesia care unit (PACU)] at Massachusetts General Hospital in Boston, Massachusetts, USA. PATIENTS Quantitative TOFR measurements obtained on admission to the PACU were available from 2144 adult noncardiac surgical patients. MAIN OUTCOME MEASURE Presence of rNMB at PACU admission, defined as a TOFR of less than 0.9. RESULTS In the score development cohort (n=2144), rNMB occurred in 432 cases (20.2%). Ten independent predictors for residual paralysis were identified and used for the score development. The final model included: hepatic failure, neurological disease, high-neostigmine dose, metastatic tumour, female sex, short time between neuromuscular blocking agent administration and extubation, aminosteroidal neuromuscular blocking agent, BMI more than 35, absence of nurse anaesthetist and having an experienced surgeon. The model discrimination by C statistics was 0.63, 95% confidence interval (0.60 to 0.66), and risk categories derived from the REPS had a higher accuracy than the last documented intra-operative TOFC for predicting rNMB (net reclassification improvement score 0.26, standard error 0.03, P

Association of pre-operative troponin levels with major adverse cardiac events and mortality after noncardiac surgery: A systematic review and meta-analysis

BACKGROUND Circulating cardiac troponin levels are powerful predictors of prognosis in many clinical settings, but their association with outcomes after noncardiac surgery is unclear. OBJECTIVES The aim of this systematic review was to summarise current evidence on the association of pre-operative troponin elevation with postoperative major adverse cardiac events (MACE) and mortality in patients undergoing noncardiac surgery. DESIGN Systematic review of observational studies with meta-analysis. DATA SOURCES PubMed, EMBASE and Science Citation Index Expanded (ISI Web of Science) from their inception to 1 October 2017. ELIGIBILITY CRITERIA Observational studies reporting the associations between pre-operative troponin levels and MACE and all-cause mortality after noncardiac surgeries were included. RESULTS Ten studies met the eligibility criteria. The entire body of evidence addressing the research question was based on a total of 10 371 patients: 4.7 to 68.3% (median 23.8%) of patients had elevated troponin levels before surgery. Elevated pre-operative troponin was significantly associated with short-term MACE (seven studies, 5180 patients: odds ratio (OR) 6.92, 95% confidence interval (CI) 3.85 to 12.42), short-term mortality (five studies, 6103 patients: OR 4.23, 95% CI 2.27 to 7.89) and long-term mortality (two studies, 760 patients: OR 2.51, 95% CI 1.47 to 4.29). The associations remained significant when only multivariate-adjusted results were analysed. Overall, the reviewers' certainty about the summary estimates of the associations was very low. CONCLUSION Current evidence suggests that pre-operative high troponin levels are significantly associated with adverse cardiac events and mortality after noncardiac surgery.

Oral ulcer due to dabigatran capsule

Description 

An 80-year-old man with cerebral infarction and no neurological deficits was hospitalised for right empyema. Although the patient's condition improved with antimicrobial therapy and right thoracic drainage, a swelling in his right cheek was observed during clinical rounds. Oral examination revealed ulceration on the right buccal mucosa (figure 1A) with an embedded blue solid matter (figure 1B), which was removed. After confirming the history of prescribed medications, the removed matter was determined to be a dabigatran capsule (figure 1C), and oral ulcer due to dabigatran was suspected. With conservative measures, re-epithelialisation was achieved within 2 weeks.

Deep vs. moderate neuromuscular blockade during laparoscopic surgery: A systematic review and meta-analysis

BACKGROUND Previous studies have reported that deep neuromuscular block (posttetanic-count 1 to 2 twitches) improves surgical conditions during laparoscopy compared with moderate block (train-of-four count: 1 to 2 twitches). However, comparisons of surgical conditions were made using different scales and assessment intervals with variable results. OBJECTIVE To explore the heterogeneity of previous comparisons between deep and moderate neuromuscular block. DESIGN Systematic review and meta-analysis of randomised controlled trials (RCTs). DATA SOURCES Medline, EMBASE and Cochrane Central Register of Controlled Trials were searched from inception to October 2017. ELIGIBILITY CRITERIA Our meta-analysis included RCTs comparing the effects of deep with moderate neuromuscular block on surgical field conditions during laparoscopic surgery. The frequency of excellent or good operating conditions on a surgical rating scale was compared. Heterogeneity was assessed by subgroup analyses. RESULTS Eleven RCTs involving 844 patients were included. On the surgical rating scale, the frequency of excellent or good operating conditions was higher with deep block compared with a moderate block (odds ratio 2.83, 95% confidence interval 1.34 to 5.99, P = 0.007, I2 = 59%). We analysed surgical rating according to the number of assessments made. There was a significant difference in surgical rating with multiple assessments, but no difference when the assessment was made on only one occasion. A significant difference in rating was noted with variable abdominal pressures; there was no significant difference with the same fixed abdominal pressure. Trial sequential analysis demonstrated that the cumulative z-curve crossed the O′Brien–Fleming significance boundary. However, required information size was not achieved. CONCLUSION Deep block was associated with excellent or good surgical rating more frequently than moderate block. However, this finding was not consistent on subgroup analyses based on frequencies of assessment of surgical conditions and abdominal pressure. Further studies are required to address the heterogeneity and power shortage demonstrated by the trial sequential analysis.

Intra-operative cutaneous temperature monitoring with zero-heat-flux technique (3M SpotOn) in comparison with oesophageal and arterial temperature: A prospective observational study

BACKGROUND Continuous monitoring of core temperature is essential during major surgery as a way of improving patient safety. Oesophageal probes or specific arterial catheters are invasive methods used in this setting. A new noninvasive device based on zero-heat-flux (ZHF) technique (SpotOn) seems promising but has been poorly investigated during rapid core temperature changes (RCTC). OBJECTIVE To assess the accuracy of a SpotOn sensor vs. an oesophageal probe or specific arterial catheter during a slow change in core temperature of less than 1 °C within 30 min and RCTC ≥ 1 °C within 30 min. DESIGN Prospective observational study. SETTING Operating rooms at the University Hospital of Poitiers, France. PATIENTS Fifty patients scheduled for major abdominal surgery under general anaesthesia were enrolled from June 2015 to March 2016. Data from 49 patients were finally analysed. Among these, 15 patients were treated with hyperthermic intraperitoneal chemotherapy. INTERVENTION Each patient had a ZHF sensor placed on the skin surface of the forehead (TempZHF) and an oesophageal probe (TempEso) used as a reference method. Twenty-two patients also had a thermodilution arterial catheter (TempArt) placed in the axillary artery. MAIN OUTCOME MEASURES Core temperature was continuously recorded from the three devices after induction of anaesthesia. Comparison of temperature measurements between methods was made using the Bland and Altman method during two separate periods according to the speed of core temperature changes. RESULTS Compared with TempEso, bias and limits of agreement for TempZHF were 0.1 ± 0.5 °C during slow core temperature changes periods and 0.6 ± 1.8 °C during RCTC periods (P = 0.0002). Compared with TempArt, these values were −0.1 ± 0.4 and 0.5 ± 1.7 °C, respectively (P = 0.0039). The ZHF sensor was well tolerated. CONCLUSION A SpotOn sensor using the ZHF method seems reliable for core temperature monitoring during abdominal surgery when variations in core temperature are slow rather than rapid.

Diagnostic accuracy of inferior vena caval respiratory variation in detecting fluid unresponsiveness: A systematic review and meta-analysis

BACKGROUND The accuracy of respiratory variation of the inferior vena cava (rvIVC) in predicting fluid responsiveness, particularly in spontaneously breathing patients is unclear. OBJECTIVES To consider the evidence to support the accuracy of rvIVC in identifying patients who are unlikely to benefit from fluid administration. DESIGN Systematic review and meta-analysis. DATA SOURCE We searched MEDLINE, EMBASE, Cochrane Library, KoreaMed, LILCAS and WHO Clinical Trial Registry from inception to June 2017. ELIGIBILITY CRITERIA Case–control or cohort studies that evaluated the accuracy of rvIVC in living adult humans were included. A study was included in the meta-analysis if data enabling construction of 2 × 2 tables were reported, calculated or could be obtained from authors and met the above cited criteria. RESULT A total of 23 studies including 1574 patients were included in qualitative analysis. The meta-analysis involved 20 studies and 761 patients. Pooled sensitivity and specificity of rvIVC in 330 spontaneously breathing patients were 0.80 [95% confidence interval (CI) 0.68 to 0.89] and 0.79 (95% CI 0.60 to 0.90). Pooled sensitivity and specificity of rvIVC in 431 mechanically ventilated patients were 0.79 (95% CI 0.67 to 0.86) and 0.70 (95% CI 0.63 to 0.76). CONCLUSION Decreased inferior vena caval respiratory variation is moderately accurate in predicting fluid unresponsiveness both in spontaneous and mechanically ventilated patients. The findings of this review should be used in the appropriate clinical context and in conjunction with other clinical assessments of fluid status. IDENTIFIER CRD 42017068028.

Haemodilution and head-down tilting induce functional injury in the rat optic nerve: A model for peri-operative ischemic optic neuropathy

BACKGROUND Mechanisms of peri-operative ischaemic optic neuropathy remain poorly understood. Both specific pre-operative and intra-operative factors have been examined by retrospective studies, but no animal model currently exists. OBJECTIVES To develop a rodent model of peri-operative ischaemic optic neuropathy. In rats, we performed head-down tilt and/or haemodilution, theorising that the combination damages the optic nerve. DESIGN Animal study. SETTING Laboratory. ANIMALS A total of 36 rats, in four groups, completed the functional examination of retina and optic nerve after the interventions. INTERVENTIONS Anaesthetised groups (n>8) were supine (SUP) for 5 h, head-down tilted 70° for 5 h, head-down tilted/haemodiluted for 5 h or SUP/haemodiluted for 5 h. We measured blood pressure, heart rate, intra-ocular pressure and maintained constant temperature. MAIN OUTCOME MEASUREMENTS Retinal function (electroretinography), scotopic threshold response (STR) (for retinal ganglion cells) and visual evoked potentials (VEP) (for transmission through the optic nerve). We imaged the optic nerve in vivo and evaluated retinal histology, apoptotic cells and glial activation in the optic nerve. Retinal and optic nerve function were followed to 14 and 28 days after experiments. RESULTS At 28 days in head down tilted/haemodiluted rats, negative STR decreased (about 50% amplitude reduction, P = 0.006), VEP wave N2-P3 decreased (70% amplitude reduction, P = 0.01) and P2 latency increased (35%, P = 0.003), optic discs were swollen and glial activation was present in the optic nerve. SUP/haemodiluted rats had decreases in negative STR and increased VEP latency, but no glial activation. CONCLUSION An injury partly resembling human ischaemic optic neuropathy can be produced in rats by combining haemodilution and head-down tilt. Significant functional changes were also present with haemodilution alone. Future studies with this partial optic nerve injury may enable understanding of mechanisms of peri-operative ischaemic optic neuropathy and could help discover preventive or treatment strategies.

Bilateral parameatal cysts with associated hypospadias presenting in a newborn baby

Description 

A male infant presented to the neonatal team on day 1 of life with concerns over cysts on his penis. He had been born at term in good condition following an emergency caesarean section for face presentation and suboptimal cardiotocograph. There was no relevant antenatal history of note and no significant family history.

He had a normal examination other than his genitalia. He had a coronal hypospadias with two symmetrical cystic lesions measuring 2–3 mm each on the glans penis, just distal and lateral to the opening of the urethral meatus on the ventral surface (figure 1). There was no obvious discharge or surrounding erythema. By day 2, there was some mild superficial ulceration of the cyst surfaces. Both testes were palpable in his scrotum. He was discharged home after confirmation of a good urinary stream.

Deep neuromuscular blockade and surgical conditions during laparoscopic ventral hernia repair: A randomised, blinded study

BACKGROUND Laparoscopic ventral hernia repair is a common surgical procedure. However, muscle contractions and general muscle tension may impair the surgical view and cause difficulties suturing the hernial defect. Deep neuromuscular blockade (NMB) paralyses the abdominal wall muscles and may help to create better surgical conditions. OBJECTIVES The current study investigated if deep compared with no NMB improved the surgical view during laparoscopic ventral hernia repair. DESIGN Crossover study. SETTING The study was carried out at Herlev and Gentofte Hospital, University of Copenhagen, Denmark and conducted from May 2015 until February 2017. PARTICIPANTS A total of 34 patients were randomised in an investigator-initiated, assessor-blinded crossover design of deep vs. no NMB during laparoscopic ventral hernia repair. INCLUSION CRITERIA Adults scheduled for elective laparoscopic ventral hernia repair. EXCLUSION CRITERIA Known allergy to any study medication, known homozygous variants in the butyrylcholinesterase gene, severe renal disease, neuromuscular disease, lactating or pregnant women, any indication for rapid sequence induction. INTERVENTIONS Deep NMB was established with rocuronium and reversed with sugammadex. Anaesthesia was conducted with propofol and remifentanil. MAIN OUTCOME MEASURES The primary outcome was evaluation of surgical view assessed on a five-point rating scale. Other outcomes included the surgical conditions during laparoscopic suturing of the hernia defect. RESULTS We found no difference in ratings for the surgical view when comparing deep with no NMB: mean −0.1 (95% confidence interval −0.4 to 0.2) (P = 0.521, paired t test). However, deep compared with no NMB improved the rating score for surgical conditions while suturing the hernia defect (P = 0.012, Mann–Whitney U test). No differences were found in either total length of surgery (P = 0.76) or hernia suturing time (P = 0.81). CONCLUSION Deep compared with no NMB did not change the rating score of the surgical view immediately after introduction of trocars during laparoscopic ventral hernia repair, but the surgical condition were improved during suturing of the hernia.

Sarcoidosis and HIV infection in a native Saudi man

Sarcoidosis is a rare condition among native Saudis. It typically presents with asymptomatic chest radiographs, exertional breathlessness and cough. The coexistence of sarcoidosis and HIV is also rare, and the overlap of the symptoms makes their differential diagnosis challenging. Nevertheless, the outcome of sarcoidosis is favourable with or without the presence of HIV. We present a case of a 55-year-old native Saudi man with extremely atypical sarcoidosis presentation coexisting with HIV. This case highlights the association between the two pathologies, and the difficulties encountered in establishing a proper diagnosis in the presence of two overlapping diseases.

End-tidal carbon dioxide monitoring improves patient safety during propofol-based sedation for breast lumpectomy: A randomised controlled trial

BACKGROUND The use of sedation is becoming more commonplace. Although pulse oximetry is a standard monitoring procedure during sedation, it cannot accurately detect early hypoventilation. End-tidal carbon dioxide (EtCO2) monitoring can be an earlier indicator of airway compromise; however, the existing literature is limited to a few studies with varying outcomes. OBJECTIVES To evaluate whether EtCO2 monitoring decreases the incidences of CO2 retention and apnoeic events in propofol-based sedation. DESIGN Randomised controlled study. SETTING A tertiary hospital. PATIENTS Two hundred women (aged 18 to 65 years, ASA physical status 1 or 2) who were scheduled for breast lumpectomy between June 2017 and August 2017. INTERVENTIONS Patients were allocated randomly to receive either standard monitoring or standard monitoring and EtCO2 monitoring. MAIN OUTCOME MEASURES The primary outcome was the incidence of CO2 retention. The secondary outcomes were the number of actions taken to restore ventilation, variations in PaCO2 and pH, the frequency of apnoea and the recovery time. RESULTS CO2 retention occurred significantly less often in the EtCO2 monitoring group (10 vs. 87%; P

Heart of the matter: reverse takotsubo syndrome in an anthracycline-exposed oncology patient

A 24-year-old man with acute myelogenous leukaemia and a history of anthracycline treatment is hospitalised for non-anthracycline chemotherapy. He develops new-onset heart failure requiring intesive care unit (ICU) admission during his stay. There is debate as to the aetiology of his heart failure, whether anthracycline cardiotoxicity or takotsubo syndrome. He is diuresed and discharged home with close follow-up. Ultimately, the retrospective use of two-dimensional speckle-tracking echocardiography derived strain helps diagnose reverse takotsubo syndrome.

Dexamethasone concentration affecting rocuronium-induced neuromuscular blockade and sugammadex reversal in a rat phrenic nerve-hemidiaphragm model: An ex vivo study

BACKGROUND The concentration range of dexamethasone that inhibits neuromuscular blockade (NMB) and sugammadex reversal remains unclear. OBJECTIVE To evaluate the effects of dexamethasone on rocuronium-induced NMB and sugammadex reversal. DESIGN Ex vivo study. SETTING Asan Institute for Life Sciences, Asan Medical Center, Korea, from July 2015 to November 2015. ANIMALS One hundred sixty male Sprague–Dawley rats. INTERVENTIONS We assessed the effect of four concentrations of dexamethasone [0, 0.5, 5 (clinical concentrations) and 50 μg ml−1 (experimental concentration)] on partial NMB on 40 phrenic nerve–hemidiaphragm preparations (n=10 per concentration). Once the first twitch of train-of-four (TOF) had been depressed by 50% with rocuronium, dexamethasone was administered. To assess the effect of dexamethasone on sugammadex reversal, 120 phrenic nerve–hemidiaphragm preparations were used in three subexperiments (n=40 per experiment), using three administration regimens of rocuronium–equimolar sugammadex: a single dose, a split-dose (split 1/2 and 1/2) and a reduced split-dose (split 1/2 and 1/4). After complete NMB was achieved, dexamethasone and sugammadex were administered. MAIN OUTCOME MEASURES The change in the first twitch height, the recovery time to a TOF ratio at least 0.9, and the TOF ratio at 30 min were evaluated. RESULTS There were no significant differences in the first twitch height among groups (P = 0.532). With a single dose of sugammadex, dexamethasone did not affect the recovery time to a TOF ratio at least 0.9 (P = 0.070). After using a split-dose of sugammadex, the recovery time to a TOF ratio at least 0.9 was delayed only at a concentration of 50 μg ml−1 of dexamethasone. With a reduced split-dose of sugammadex, the TOF ratio at 30 min was lowered only by a concentration of 50 μg ml−1 of dexamethasone (P

Hereditary angioedema: a mother diagnosing her child using Google as a diagnostic aid

Hereditary angioedema (HAE), due to C1-inhibitor deficiency, is a rare autosomal dominant and potentially life-threatening disease characterised by recurrent oedema attacks of skin, mucosa and viscera. Due to the rarity and the fact that symptoms of HAE imitate other forms of angioedema and other conditions, HAE may be misdiagnosed, especially in emergency settings. Consequently, patients with HAE may experience significant delays in diagnosis. Without an accurate diagnosis patients with HAE may not receive proper treatment. At times 'Doctor Google' may be an important tool in establishing the diagnosis. The aim of this case report is to emphasise the importance of listening to patients and relatives and being humble to 'Doctor Google'. Furthermore, the aim is to remind all healthcare personal of HAE and the importance of considering the rare differential diagnoses to common symptoms.

Borderline Mucinous Testicular Tumour: Diagnostic and Management difficulties

A 45-year-old man presented with right-sided testicular swelling and pain. An examination found a tender, firm right testis, a clinically normal left testis and no palpable lymphadenopathy. Tumour and inflammatory markers were within normal limits. A scrotal ultrasound scan showed an intratesticular, avascular lesion measuring 4.4x2.6x1.8 cm. A CT scan of his chest/abdomen/pelvis (CT C/A/P) showed no metastatic or primary lesions. An elective right-inguinal orchidectomy was subsequently performed. Histopathology showed a cystic mucinous tumour lined with intestinal-type epithelium. Differentials of metastatic adenocarcinoma, possibly of a gastrointestinal origin, a monodermal teratoma, or a borderline mucinous tumour of the testicle (BMTT) were considered. Following 12 p genetic studies and a colonoscopy, both of which found no abnormalities, a presumptive diagnosis of a BMTT was made. The patient is to have an annual urological review with a CT C/A/P and 5 yearly colonoscopies.

Exercise for Leg Ulcers

In this issue of JAMA Dermatology, Jull et al use meta-analysis to suggest an additional healing benefit of exercise in patients with venous leg ulcers (VLUs). Combining and analyzing data from 5 relatively small studies (the largest with 63 participants), the authors found that 61% of participants (57 of 94) who exercised and received compression healed at 12 weeks compared with 46% (44 of 96) of participants who received compression alone. Although the type of exercise administered varied among the trials, the results were driven by 2 studies that used progressive resistance exercises involving calf muscle strengthening coupled with physical activity (walking). In addition to providing rationale for an adjunctive therapeutic modality for patients with VLUs, this article also highlights the power of properly performed meta-analysis to provide clarity where previously none existed.

Introducing “Images in Dermatology”

It is often said that dermatology is a "visual specialty." While it is more than that, there is no escaping the central importance of the clinical examination to dermatologic diagnosis. The appearance, the morphology, the shape and distribution of lesions—these features are the illustration of illness, the manifestation of cutaneous or even systemic disease. The critical role of the physical examination, imparting the ability to make a diagnosis visually, is part of the art of dermatology and is shared by few other medical specialties.

TGF-β1-induced airway smooth muscle cell proliferation involves TRPM7-dependent calcium influx via TGFβR/SMAD3 (Revision)

Publication date: November 2018

Source: Molecular Immunology, Volume 103

Author(s): Ming Chen, Wei Zhang, Jianting Shi, Shanping Jiang

Abstract

Background

TRPM7 in mast cells plays a key role in asthma. However, the effect of TRPM7 on TGF-β1-induced airway smooth muscle cell (ASMC) proliferation remains unclear. Therefore, we designed this study to explore whether TRPM7 is involved in TGF-β1-induced ASMC proliferation.

Methods

An asthmatic mouse model was established, and the expressions of TGF-β1 and TRPM7 in mice lungs were detected using enzyme-linked immunosorbent assay (ELISA) and western blotting. In addition, murine ASMCs were cultured and stimulated with TGF-β1. Possible TGF-β1 and TRPM7 interactions were examined using RT-PCR and western blotting analyses with ASMCs. The effect of TRPM7 knockdown on ASMC calcium influx was assessed by the fluorescent indicator indo-1. MTT and flow cytometry were applied to evaluate the effects of TRPM7 knockdown on ASMC proliferation and apoptosis.

Results

TGF-β1 elevated the expression of TRPM7 via TGFβR/SMAD3. Knocking down TRPM7 decreased the intracellular Ca²⁺ concentration and cellular proliferation of ASMCs, although apoptosis remained unaffected.

Conclusions

Our initial findings suggest that TRPM7 inhibition may prevent asthma-induced airway remodeling.

Abstract

Objective

This study aimed to determine and describe hearing loss among preschool children in a South African community representative of typical low- and middle income countries (LMIC).

Method

Children between the ages of 3-6 years received a hearing screening at their early childhood development (ECD) center. If a child failed the hearing screening, he/she was seen for a follow-up rescreen and diagnostic assessment if necessary at their ECD center or closest referral clinic. Diagnostic testing consisted of otoscopy, tympanommetry and pure-tone diagnostic audiometry.

Results

A total of 6424 children were screened at ECD centers with a referral rate of 24.9%. Follow-up assessments were conducted on 45.3% (725) of these children. Diagnostic testing revealed that 9.3% of children presented with impacted cerumen and 18.7% presented with a hearing loss (56.5% binaural). Binary logistic regression revealed no gender or age effects (p>0.05). Conductive hearing loss (65.2%) was the most common type of hearing loss found in children.

Conclusions

Most preschool children who failed the hearing screening and received a diagnostic assessment were in need of intervention services for conductive hearing losses, followed by sensorineural and mixed losses.

Abstract

Objective

Microtia/atresia is a severe malformation of the external ear. Previous studies have reported the potential risk factors on microtia, whereas few focused on severe microtia/atresia. The aim of the study was to investigate the effects of maternal exposure to environmental risk factors in patients with severe microtia/atresia in China.

Methods

A case-control study was conducted. Cases were patients with severe microtia/atresia who presented to PUMCH between January 2014 and October 2017. A total of 322 patients with severe microtia/atresia were enrolled and 322 normal controls matched 1:1 with the patients by sex, age and nationality were enrolled. The designed questionnaires were completed and data were gathered. Odds ratios were estimated with logistic regression models along with 95% confidence intervals in severe microtia/atresia.

Results

Most cases were males(68.6%), and the cases were observed more common in unilateral(80.7%), right-sided (54.0%). Multivariate logistic regression analysis showed that threatened abortion (OR 4.066,95% CI = 2.360–7.007), NSAIDs (OR 2.576,95% CI = 1.079–6.148), virus infection (OR 1.933,95% CI = 1.148–3.256), anemia (OR 1.902,95% CI = 1.026–3.526), miscarriages (OR 1.804,95% CI = 1.425–2.285), maternal age (OR 1.079,95% CI = 1.015–1.148) and paternal age (OR 1.061,95% CI = 1.003–1.122) were associated with a higher risk of severe microtia/atresia.

Conclusion

These results support that some maternal risk factors could be associated with severe microtia/atresia.

Publication date: Available online 2 October 2018

Source: American Journal of Otolaryngology

Author(s): I.I. Kevin Moore, Richard Thompson, Timothy Lian

Abstract

Importance

Repair of full-thickness nasal defects can often be associated with multi-stage operations that can result in significant physical and psychological morbidity for patients. We present a single-stage option for reconstruction of these defects.

Objective

Demonstrate the utility of the pedicled levator labii superioris alaeque nasi flap and consistency of its vascular pedicle.

Design

Anatomical study using fresh cadavers.

Setting

Academic medical center.

Main outcome and measures

Evaluation of vascular anatomy of pedicled flap and measurements of distances with relationship to facial anatomic landmarks.

Results

With few noted anatomic variations, the vascular pedicle of the pedicled levator labii superioris alaeque nasi flap arises from the superior labial artery and is reliably located within 1 cm lateral and inferior of the nasal sill.

Conclusions and relevance

As a robust single-stage option, the pedicled levator labii superioris alaeque nasi flap can serve as a powerful option in the arsenal of the reconstructive surgeon. The technique for harvest is simple with attention to a few anatomic variations as described herein, and excellent results can be obtained with proper application.

Summary

Background

Little information is available on the prevalence and clinical aspects of tongue involvement in children with psoriasis. The aim was to evaluate the prevalence, clinical aspects and risk factors concerning tongue involvement in children with psoriasis.

Patients and methods

This study was carried out in two stages. We performed a multicentre, cross-sectional study in 23 French dermatology centers. All children seen for psoriasis during the one-year study were systematically included. The clinical features of the tongue and of psoriasis were recorded. Association with clinical aspects of psoriasis and comorbidities was evaluated. We then carried out a literature review to evaluate the prevalence of tongue involvement in children with psoriasis and its positive predictive value for psoriasis. A search was conducted in the PUBMED database using the following keywords: "child" and "psoriasis" and ("tongue" or "glossitis" or "migratory glossitis" or "benign migratory glossitis" or "geographic tongue" or "fissured tongue").

Results

7.7% of the 313 children with psoriasis had tongue involvement. The clinical aspects were geographic tongue (4.2%), fissured tongue (2.8%) and both (0.64%). There was no association between tongue involvement and the clinical characteristics of the children. Two hundred and ninety-five articles were referenced and 3 were analysed. Psoriasis is very rare in cases of tongue abnormalities.

Conclusion

The prevalence of tongue involvement was 7.7% in children with psoriasis. No clinical or epidemiological association was shown. Tongue involvement does not modify the management of psoriasis. In the literature review it was not possible to evaluate either the prevalence of tongue involvement in psoriasis or the positive predictive value thereof.

Résumé

Introduction

Il y a peu d'informations dans la littérature sur les atteintes de la langue au cours du psoriasis de l'enfant. L'objectif était d'évaluer la fréquence, les aspects cliniques et les facteurs de risque d'atteinte linguale chez les enfants psoriasiques.

Patients et méthodes

Ce travail a été effectué en deux étapes : (1) une étude transversale a été menée dans 23 centres dermatologiques français, notant les aspects cliniques de la langue et du psoriasis chez les enfants atteints de psoriasis, ainsi que les associations et les comorbidités ; (2) une revue systématique de la littérature a ensuite été effectuée afin d'évaluer la prévalence l'atteinte linguale chez l'enfant et sa valeur prédictive du psoriasis. Une recherche a été réalisée en interrogeant la base de données PUBMED. Les mots clés saisis étaient : « child » et « psoriasis » et (« tongue » ou « glossitis » ou « migratory glossitis » ou « benign migratory glossitis » ou « geographic tongue » ou « fissured tongue »).

Résultats

(1) Parmi 313 enfants atteints de psoriasis 7,7 % présentaient une atteinte linguale sous forme de langue géographique (4,2 %), langue fissurée (2,8 %) ou les deux (0,6 %). L'atteinte linguale n'était associée à aucune particularité démographique ou clinique, ni aucune comorbidité. (2) Parmi 295 articles référencés, 3 ont finalement été retenus. Le psoriasis reste très rare en cas d'anomalie linguale.

Conclusion

La prévalence de l'atteinte linguale chez les enfants psoriasiques était de 7,7 %. Aucune association clinique ou épidémiologique n'a été montrée. L'atteinte linguale ne modifie pas la prise en charge du psoriasis. La revue systématique de la littérature ne permettait pas d'évaluer une prévalence de l'atteinte linguale dans le psoriasis ni la valeur prédictive positive de cette atteinte.

Retrieval of a retained video capsule endoscope with laparoscopic surgery

Abstract

Capsule endoscopy (CE) is commonly used for examining and diagnosing gastrointestinal disease, especially small bowel disease. Capsule retention is a well-known and significant complication of CE and requires surgical or endoscopic removal. Most reports described the retrieval of retained CE via laparotomy. We report a case of successful retrieval of the capsule using laparoscopic surgery.

An autologous dendritic cell vaccine polarizes a Th-1 response which is tumoricidal to patient-derived breast cancer cells

Abstract

Breast cancer remains one of the leading causes of cancer-associated death worldwide. Conventional treatment is associated with substantial toxicity and suboptimal efficacy. We, therefore, developed and evaluated the in vitro efficacy of an autologous dendritic cell (DC) vaccine to treat breast cancer. We recruited 12 female patients with stage 1, 2, or 3 breast cancer and matured their DCs with autologous tumour-specific lysate, a toll-like receptor (TLR)-3 and 7/8 agonist, and an interferon-containing cocktail. The efficacy of the vaccine was evaluated by its ability to elicit a cytotoxic T-lymphocyte response to autologous breast cancer cells in vitro. Matured DCs (≥ 60% upregulation of CD80, CD86, CD83, and CCR7) produced high levels of the Th1 effector cytokine, IL12-p70 (1.2 ng/ml; p < 0.0001), compared to DCs pulsed with tumour lysate, or matured with an interferon-containing cocktail alone. We further showed that matured DCs enhance antigen-specific CD8 + T-cell responses to HER-2 (4.5%; p < 0.005) and MUC-1 (19%; p < 0.05) tetramers. The mature DCs could elicit a robust and dose-dependent antigen-specific cytotoxic T-lymphocyte response (65%) which was tumoricidal to autologous breast cancer cells in vitro compared to T-lymphocytes that were primed with autologous lysate loaded-DCs (p < 0.005). Lastly, we showed that the mature DCs post-cryopreservation maintained high viability, maintained their mature phenotype, and remained free of endotoxins or mycoplasma. We have developed a DC vaccine that is cytotoxic to autologous breast cancer cells in vitro. The tools and technology generated here will now be applied to a phase I/IIa clinical trial.

Closing the gap: Understanding African American asthma knowledge and beliefs

Publication date: October 2018

Source: Annals of Allergy, Asthma & Immunology, Volume 121, Issue 4

Author(s): Jade B. Tam-Williams, Bridgette L. Jones

Abstract

Background

African American children are disproportionately affected by asthma (13% vs 8% non-Hispanic white Americans) and experience 30% higher asthma-related deaths than whites. Knowledge regarding asthma and asthma treatment among African Americans has been postulated as a potential contributor to this observed health disparity. Compared with the amount of studies on asthma, few investigations provide insight into the baseline knowledge and beliefs of African Americans regarding asthma.

Objective

Assess knowledge and beliefs regarding asthma symptoms, diagnosis, treatment, prognosis, and stigmas in a general community sample of African Americans.

Methods

Using community-based participatory research techniques, we developed and implemented a cross-sectional survey to explore asthma knowledge and beliefs among African American adults in a Midwestern city.

Results

Among the 158 African American adults who completed the survey, general asthma knowledge was good, with awareness of the genetic contribution to asthma and general asthma symptomatology (eg, 92% aware of nighttime cough as a symptom). However, asthma-related misconceptions were also revealed. Thirty-three percent of respondents were concerned about addiction to asthma medication, and 60% of respondents believed that inhaled corticosteroids were dangerous or did not know.

Conclusion

This study reveals important insights into asthma knowledge and beliefs among African Americans that may be used to address disparities in asthma outcomes in this population.

Biomarkers in Food Allergy

Abstract

Purpose of Review

To familiarize the reader with the concept of precision medicine in food allergy by dealing with the current biomarkers for the diagnosis, prognosis, and management of the disease.

Recent Findings

Many efforts have been devoted in order to characterize reliable biomarkers able to identify specific phenotypes and endotypes in food allergy. Specific IgE (sIgE), sIgE/total IgE ratios, and T cell assays are just a few candidates that have been investigated over time. With the advent of omics sciences, a new era is commencing. A better understanding of pathogenesis of food allergy and mechanisms of action of the different therapeutic options will allow the accurate selection of the appropriate patient.

Summary

In the near future, advances in technologies and data interpretation will allow a better understanding of the pathogenesis of food allergy and the identification of proper biomarkers for a personalized treatment tailored on the specific patient's profile.

Relation between adenoid size and otitis media with effusion

Publication date: Available online 2 October 2018

Source: European Annals of Otorhinolaryngology, Head and Neck Diseases

Author(s): L. Skoloudik, D. Kalfert, T. Valenta, V. Chrobok

Abstract

Aims

This study compares the efficacy of adenoidectomy on otitis media with effusion (OME) in patients with different size of adenoids and the connection between differently sized adenoids and middle ear effusion.

Material and methods

Children with a history of at least 3 months' OME underwent adenoidectomy and myringotomy without the insertion of a tympanostomy tube. Treatment assignment was stratified by adenoids' size causing choanal obstruction (grade I-III) and according to Eustachian tube ostium obstruction (grade A–C). The subjects were followed for 12 months.

Results

Adenoidectomy was significantly more effective in children with adenoids in contact with torus tubarius (grade B, C) compared to those with small adenoids without contact (P < 0.001). The volume of the adenoids was irrelevant (P = 0.146). The size of adenoids did not affect the viscosity of the middle ear secretion. The distribution of mucous and serous secretion was not dependent on the size of adenoids; the efficacy of adenoidectomy was 82% in mucous as well as serous secretion.

Conclusion

The relation between adenoids and torus tubarius is more important than the volume of the adenoids. The viscosity of middle ear fluids (serous or mucous) did not influence the rate of treatment efficacy.

Flow cytometric assessment of leukocyte kinetics for the monitoring of tissue damage

Publication date: Available online 2 October 2018

Abstract

Leukocyte populations quickly respond to tissue damage, but most leukocyte kinetic studies are not based on multiparameter flow cytometry. We systematically investigated several blood leukocyte populations after controlled tissue damage. 48 patients were assigned to either an anterior or posterolateral total hip arthroplasty. Peripheral blood was collected pre-operatively and at 2 h, 24 h, 48 h, 2 and 6 weeks postoperatively and assessed by flow cytometry for absolute counts of multiple leukocyte populations using standardized EuroFlow protocols. Absolute counts of leukocyte subsets differed significantly between consecutive time points. Neutrophils increased instantly after surgery, while most leukocyte subsets initially decreased, followed by increasing cell counts until 48 h. At two weeks all leukocyte counts were restored to pre-operative counts. Immune cell kinetics upon acute tissue damage exhibit reproducible patterns, which differ between the leukocyte subsets and with "opposite kinetics" among monocyte subsets. Flow cytometric leukocyte monitoring can be used to minimally invasively monitor tissue damage.

Surgical Excision with Rotational Flap Reconstruction for Basosquamous Cell Carcinoma in Xeroderma Pigmentosa: A Case Report

Abstract

Xeroderma pigmentosa (XP) is a rare autosomal recessive disorder which is characterized by a defect in nucleotide excision repair of DNA following exposure to UV radiation. This leads to hypersensitivity to sunlight causing pigmented skin lesions, photophobia and a 1000-fold increase in risk of developing cutaneous malignancies like basal cell carcinomas, squamous cell carcinomas and melanomas of head and neck. We present an interesting case of a 28 year old man with basosquamous cell carcinoma secondary to XP treated successfully with surgical excision and reconstruction with rotational flap technique.

A Case–Control Study on the Association Between Endoscopic ACE Grade of Adenoid Hypertrophy and Hearing Loss in Children and Its Impact on Speech and Language Development

Abstract

To establish an association between adenoid hypertrophy and hearing loss and its impact on speech and language in pediatric age group. A prospective case control study done in a tertiary hospital in South India. Twenty children with hearing loss were recruited in the study group and twenty-four children as controls. These groups underwent at detailed otorhinolaryngologic examination, hearing and speech evaluation. The size of the adenoids was graded endoscopically. Findings between the two groups were compared and analysed. Our study found statistically significant association between adenoid hypertrophy with choanal obstruction and abutment of eustachian tube opening seen on endoscopy with hearing loss (p = 0.025). The children with hearing loss also had speech and language delay (p = 0.004). Children with enlarged adenoids obstructing the > 50% of the choanae or abutting the eustachian tube opening are more likely to have hearing loss and may develop speech and language delay. The ACE endoscopic adenoid grading system is consistent and reliable in evaluation of adenoids.

Geriatric Dysphonia: Etiological Analysis in a Rural Hospital in India

Abstract

To establish the prevalence of etiological factors for dysphonia in elderly individuals in rural India. Hundred adults aged ≥ 65 years, who presented with dysphonia for ≥ 4 weeks and underwent detailed clinical evaluation including videolaryngoscopic assessment and other appropriate investigations/evaluation, were included in a retrospective cohort clinical study. Patients were classified into eight groups for further descriptive statistical analysis based on standard diagnostic criteria/guidelines i.e. benign vocal cord lesions, inflammatory disorders of the larynx, laryngeal and hypopharyngeal neoplasms, isolated vocal cord palsy/paresis, presbylaryngis, central neurological disorders affecting laryngeal function, impaired pulmonary function and non specific dysphonia. Mean age was 70.73 ± 4.29 years. 58% were aged between 65 and 69 years. Overall, the common causes for dysphonia were laryngopharyngeal reflux disease (23%), carcinoma larynx (12%) and presbylaryngis (8%). Inflammatory disorders of the larynx, benign vocal cord lesions and laryngeal/hypopharyngeal malignancies were the commonest causes for dysphonia in individuals aged between 65 and 74 years. Presbylaryngis and systemic causes were the commonest among individuals aged 75–89 years. 63 males and 37 females met the inclusion criteria. The most common cause for dysphonia among females was laryngopharyngeal reflux disease (17%), followed by vocal palsy (5%) and spasmodic dysphonia (4%). Carcinoma larynx (12%) was the most common cause for dysphonia among males, followed by laryngopharyngeal reflux (6%) and presbylaryngis (6%). Geriatric dysphonia is an often overlooked symptom of greater underlying disease as evidenced in this study. With its impact on the quality of life in this age group and life expectancy in the rural population, dysphonia requires early detection, prompt evaluation and appropriate management.

Label-free Identification of Antibody-mediated Rejection in Cardiac Allograft Biopsies Using Infrared Spectroscopic Imaging

BACKGROUND Antibody-mediated rejection (AMR) in cardiac allograft recipients remains less well-understood than acute cellular rejection, is associated with worse outcomes, and portends a greater risk of developing chronic allograft vasculopathy. Diffuse immunohistochemical (IHC) C4d staining of capillary endothelia in formalin-fixed, paraffin-embedded (FFPE) right ventricular (RV) endomyocardial biopsies is diagnostic of immunopathologic AMR but serves more as a late-stage marker. Infrared (IR) spectroscopy may be a useful tool in earlier detection of rejection. We performed mid-IR spectroscopy to identify a unique biochemical signature for AMR. METHODS A total of 30 posttransplant FFPE RV tissue biopsies (14 positive for C4d and 16 negative for C4d) and 14 native heart biopsies were sectioned for IR analysis. IR images of entire sections were acquired and regions of interest (ROI) from cardiomyocytes were identified. Extracted spectra were averaged across many pixels within each ROI. Principal component analysis coupled with linear discriminant analysis (PCA-LDA) and predictive classifiers were applied to the data. RESULTS Comparison of averaged mid-IR spectra revealed unique features among C4d-positive, C4d-negative, and native heart biopsies. PCA-LDA and classification models demonstrated that spectral features from the mid-IR fingerprint region of these 3 groups permitted accurate automated classification into each group. CONCLUSIONS In cardiac allograft biopsies with immunopathologic AMR, IR spectroscopy reveals a biochemical signature unique to AMR compared to that of nonrejecting cardiac allografts and native hearts. Future study will focus on the predictive capabilities of this IR signature.
