Bullous Pemphigoid in an Infant: A Case Report.

A seven-month-old girl was referred to the emergency department (ED) after a general practitioner suspected Steven-Johnson syndrome. Actually, the diagnosis of bullous pemphigoid (BP) was made based on biopsies; BP is a rare, autoimmune skin disease involving the presence of blisters known as bullae. The child was efficiently treated with topical steroids. This case shows the importance of the ED physician's prior knowledge of BP so that a differential diagnosis with other autoimmune diseases (dermatosis, pemphigus) can be made.Thabouillot O, Le Coz J, Roche NC.

Seven years follow-up of early repolarisation patterns in French elite special forces.

BACKGROUND: The early repolarization pattern (ERP) may be a marker of increased risk for sudden cardiac death (SCD). Influence of ethnicity on the ERP has not been extensively studied. The aim of this study was to evaluate the epidemiology of ERP in a male multiethnic population. METHODS: ECG analysis was performed among consecutive recruits from the French Foreign Legion. ERP was characterized by a J-point elevation ≥0.1 mV in two continuous inferior-lateral leads, and high amplitude early repolarization (HAER-potentially malignant pattern) by an elevation ≥0.2 mV. Ethnical affiliation and level of physical activity were recorded. RESULTS: A total of 2508 healthy men (24 ± 5 years old) from 105 different native countries were divided into three ethnic groups: 1689 Whites, 388 Afro-Caribbean, and 431 Asians. ERP was found in 489 recruits (19%), 14% in Whites, 33% in Afro-Caribbeans, and 27% in Asians without any difference according to age and physical activity. Sub-Saharan Africans or Caribbeans had the highest rate of ERP (30%), and Hispanics the lowest (8%). People from occidental countries, Middle East, Central Asia or India had a rate of 12%-18%, East and South-Asia 20%-25%. Madagascar was an exception with only 16% of ERP. HAER (2.9%) was more frequent among Asian recruits. After 5 ± 2 years of follow up, one SCD occurred in the ERP group (p = 0.042). CONCLUSION: This study reports a large multiethnic analysis of ERP. HAER was more frequent in recruits from East and South-East Asia where sudden unexplained nocturnal death syndrome is endemic.

Prepare for Take-Off: Fasten Your Seatbelt and Keep a Magnet in Your Pocket!

Fainting on a plane is quite common, and stewards are used to taking care of things. Statistically, there is always a physician on board. This Letter to the Editor details a case report that deals with inappropriate pacemaker inhibition during a flight. Roche NC , Thabouillot O , Bouvier F , Paule P.

Syncope During Competitive Events: Interrogating Heart Rate Monitor Watches May Be Useful!

This is a case report of a 45-year-old man who reported complete amnesia during the very first kilometer of a 10-km run. He was wearing a heart rate monitor (HRM). The interrogation of his HRM watch showed 200 bpm tachycardia beginning in the first kilometer and increasing up to 220 bpm during the last kilometer. The patient was asked to wear a Holter-monitor (Holter Research Laboratory; Helena, Montana USA) electrocardiogram (ECG) while practicing a training session. This examination allowed for the diagnosis of an adrenergic paroxysmal atrial fibrillation (AF) with an impressive auriculo-ventricular conduction over 260 bpm. This case highlights that non-medical devices, such as connected watches, can be helpful to diagnose arrhythmias.

A Fortunate Story of an Unusual AK-47 Bullet Trajectory: Always Keep a Smartphone in Your Pocket.

This is a report of a fortunate story of an unusual AK-47 bullet trajectory which took place during the Paris (France) attack of November 13th, 2015. A young man, trying to protect his girlfriend, interfered between her and a shooter. He had been wounded in the posterior compartment of the thigh. The bullet penetrated him and, instead of exiting, rebound against his Smartphone, which was in the front pocket of his pants. Thanks to that, the missile bullet did not injure his girlfriend but ended its trajectory in the fat tissue of his thigh.

Cardiovascular disease in children in Djibouti: a single-centre study.

INTRODUCTION: Few data are available about pediatric cardiovascular disease (CVD) in the Horn of Africa. The objective of this study was to describe the spectrum of CVD in children in Djibouti. METHODS: Clinical features and management of Djiboutian children between 1 month-old and 15 year-old with CVD were prospectively recorded over a two-year period in Bouffard Military Hospital in Djibouti (January 2009- December 2010). RESULTS: Clinical examination and echocardiography were performed on 156 patients: 32 of them (20%) had CVD. Three (10%) of them had Down's syndrome. The median age was 5 years (male 53%). Congenital heart disease was observed in 27 (84%) patients and dilated cardiomyopathy (DCM) in 5 (16%) patients including 2 patients with rheumatic valvular disease. Ventricular septal defect was frequent (28%). Other abnormalities were atrial septal defect (13%), Tetralogy of Fallot (9%), pulmonary stenosis (6%) and 3 other patients had multiple congenital anomalies condition. Surgical management was required in 22 (69%) patients and was performed on 15 (47%) cases. During follow up (mean 11.3 ± 6.8 months), 5 (16%) patients died. Absence of surgery was associated with significant mortality (p > 0.05) but age, sex and mean follow up were not. CONCLUSION: Pediatric CVD is at least as common in this Djiboutian community as in other African cohorts. The absence of surgery was a major mortality risk factor. DCM was frequent in this study. Much work remains to be done to discover the size and nature of genetic and environmental contributions to these various forms of heart diseases in the Horn of Africa.

[Pancytopenia and folate deficiency: a case report]. / Pancytopénie et carence en folates : à propos d'un cas.

Anemia is the most common pathology encountered in hematology. Etiologies are numerous, so it is important to adopt a rigorous approach. Complementary examinations must be specific to the clinical situation in order to determine the mechanisms on the one hand and decide the therapeutic management on the other. We report the observation of a case of sudden onset of profound pancytopenia. Investigation led to the diagnosis of major folic acid deficiency with favorable evolution. Through this case, we describe the diagnostic approach towards anemia and the mechanisms involved in the formation of folate deficiency.
