They constitute a violation of human rights, in particular because of their harmful consequences for the health of the people who suffer them and are the source of various complications. We report a case of FGM complications in the form of total coalescence of the labia majora with a small hole from which urine flows permanently. The management was a disinfubilation with suturing of the edges and urethral reimplantation and the evolution was favorable with complete healing after two (2) weeks.展开更多

Post-operative chest wall masses can also include infection, hematoma, seroma, cancer recurrence, metastasis, and lung hernia. Bedside ultrasound has been well documented to be beneficial in the differentiation of superficial pathology. Pleurocutaneous fistula is a pathologic communication between the pleural space and subcutaneous tissues of the chest wall. Pleurocutaneous fistula is a rare complication of tube thoracostomy, video-assisted thoracic surgery （VATS） procedures, and various pulmonary infections.展开更多
