Gas Gangrene after an Intramuscular Injection: A Case Report.

Gas gangrene is a necrotic infection of soft tissue associated with a high mortality, often necessitating amputation to control the infection. It is mainly caused by Clostridium perfringens which is a Gram-positive, anaerobic, spore-bearing bacillus widely found in nature, particularly in soil and feces. Incubation time for gas gangrene is short, usually <24 h, and the physical finding of crepitus is characteristic in the setting of soft tissue infection. Herein, we present a case of gas gangrene of the gluteal region and thigh following an intramuscular injection where the patient was treated with multiple debridements, antibiotics, and hyperbaric oxygen therapy; a review of the literature is presented here.

Cecal Endometriosis: An Unusual Cause of Adult Ileocolic Intussusception.

Endometriosis is defined as the presence of endometrial tissue outside the endometrium and the myometrium. The gastrointestinal tract is the most common site for extrapelvic endometriosis, affecting 5-15% of women in the childbearing age group; the rectum and the sigmoid colon are the most common sites involved. Terminal ileal and cecal involvement is rare and may mimic malignancy of the colon. It is even rarer for endometriosis of the cecum to cause intussusception. The diagnosis of endometriosis in the ileocecal region is seldom made preoperatively in the absence of the previous endometriosis. Ileocolic endometriosis presenting predominantly as a mural mass and causing intussusception is very rare with few reports in world literature. We report a case of ileocolic endometriosis causing intussusceptions in an adult.
