Intercostal lung herniation secondary to thoracotomy: a case report.

Intercostal lung herniation is defined as a protrusion of the lung parenchyma through a defect in the intercostal muscles between adjacent ribs. The authors report a case of intercostal pulmonary hernia in a 45-year-old male patient, with smoking habit (30 packs-year), presented to the emergency department with dyspnea. He had the history of pulmonary emphysema complicated with a total right pneumothorax in 2015 treated by mini-thoracotomy with bullectomy and pleural abrasion.

Problem solving learning in emergency medicine: Effects and student's perception.

Introduction: the Problem solving Learning (PSL) is an interactive method of teaching that allows students to learn at once clinical reasoning and acquisition of knowledge. The PSL is used to assess learner's competencies.

Aim: To was to assess the educational relevance of PSL in emergency medicine and the perception of learners.

Association of MTHFR C677T, MTHFR A1298C, and MTRR A66G Polymorphisms with Neural Tube Defects in Tunisian Parents.

Objective: This study aims to investigate the association of 5,10-methylenetetrahydrofolate reductase (MTHFR C677T and A1298C) and methionine synthase reductase (MTRR A66G) gene polymorphisms with neural tube defects (NTDs) in a Tunisian population.

Methods: Genotyping was performed by polymerase chain reaction with restriction fragment length polymorphisms (PCR-RFLPs) using the restriction enzymes. Allele and genotype frequencies were compared between mothers and fathers of fetuses with NTDs with matched controls based on an association analysis using SPSS software.

The A445C Variant in Apelin Receptor and Diabetic Retinopathy in Tunisian Patients.

Background: Apelin and apelin receptor (APLN/APLNR) are involved in the retinal neovascularization of diabetic retinopathy (DR).

Methods: This study investigated the impact of the APLNR A445C variant on the risk of DR in a sample of the Tunisian population (100 patients with DR and 105 healthy controls) using PCR-RFLP.

Results: The genotype frequencies of the APLNR A445C variant were not significantly different between the patient and control groups.

Positional convulsant syncope in a pacemaker patient following insulation break of the right ventricular lead.

In spite of the advances made in the technology of pacemakers which resulted in a decrease in the incidence of pacemaker lead fracture, the latter remains a potential complication of implanted pacemakers manufactured in the early days. In this report, we present a case of fracture of the unipolar electrode diagnosed by an emergency physician in a patient on a pacemaker for 10 years who presented to the emergency department with positional convulsant syncopes.
