Anorexia nervosa is a primary behavioural disorder characterised by a disturbed sense of body image, a morbid fear of gaining weight, disturbed eating pattern, marked weight loss and amenorrhea. It usually affects adolescent women (95%).1 Medical complications of anorexia nervosa can involve all organic systems of the body.2'3 A rare complication is spontaneous pneumomediastinum, with only a fe...

Spontaneous pneumomediastinum and subcutaneous emphysema also known as Hamman's syndrome is a very rare complication of labor that is often related to the valsalva maneuver during the labor. In most case, Hamman's syndrome is a self-limiting condition, rarely complicated unless there are underlying respiratory diseases. Chest X-ray can be a useful early diagnostic technique in severe clinical p...

Subcutaneous emphysema, pneumomediastinum, and tension pneumothorax are previously unreported complications of shoulder arthroscopy with subacromial decompression. Three patients developed extensive subcutaneous emphysema, pneumomediastinum, and bilateral tension pneumothorax during or immediately after shoulder arthroscopy with subacromial decompression. The procedure was terminated and approp...

Spontaneous pneumomediastinum is a rare disease process with no clear etiology, although it is thought to be related to changes in intrathoracic pressure causing chest pain and dyspnea. We present a case of a 17-year-old male with acute chest pain evaluated initially by bedside ultrasound, which showed normal lung sliding but poor visualization of the parasternal and apical cardiac views due to...

BACKGROUND Pneumocystis jirovecii, formerly named Pneumocystis carinii, is one of the most common opportunistic infections in human immunodeficiency virus (HIV)-infected patients. CASE PRESENTATIONS We encountered two cases of spontaneous pneumomediastinum with subcutaneous emphysema in HIV-infected patients being treated for Pneumocystis jirovecii pneumonia with trimethoprim/sulfamethoxazole...

Abstract Aim Pneumomediastinum is a known radiological finding after major trauma, however its significance and required investigative workup not standardized. Furthermore, there little evidence to suggest that traumatic pneumomediastinum indicative of oesophageal injury. Our study set out investigate the rate injury for these patients at our centre, relevant work up required. Method Medical re...

To the Editor: Pneumomediastinum infrequently complicates diagnostic bronchoscopy. Increased airway or alveolar pressure results in air leaks to the mediastinum through existing or induced defects. Excessive cough, recurrent episodes of increased abdominal pressure, vomiting, or sneezing can all induce spontaneous pneumomediastinum. Less commonly it has been documented with lung or neck infecti...
