Mid-jejunal diverticulitis with closed-loop bowel obstruction, strangulation, and contained perforation.

Key Clinical Message: Closed-loop bowel obstruction and contained perforation secondary to acute on chronic jejunal diverticulitis is rare and should be included in the differential diagnosis of acute abdomen. The association between polymyalgia rheumatica and diverticular disease requires further research but may prompt clinicians to consider appropriate therapies in patients with both diseases.

Abstract: Jejunal diverticulosis is a sac-like outpouching of the intestinal wall that can cause complications such as diverticulitis, obstruction, abscess, perforation, or fistula formation.

Angioinvasive associated necrotizing fasciitis in an immunocompromised patient.

Angioinvasive dermatophytosis with necrotizing fasciitis can be a rare complication in immunocompromised patients with early surgical debridement, 12 weeks of oral terbinafine, and reduction in immunosuppression being a viable management strategy.

Perforated Appendicitis Presenting as a Soft Tissue Infection of the Thigh: An Example of Successful Non-Operative Management.

Perforated appendicitis is a rare but serious clinical scenario typically requiring urgent surgical intervention. Herein, we discuss the case of a 62-year-old woman with COVID-19 and ruptured retrocecal appendicitis presenting as a right lower extremity soft tissue infection that was successfully managed using non-operative measures. This unique case illustrates the feasibility of conservative care - rather than urgent surgical intervention - in the treatment of an atypical presentation of complicated appendicitis in a high-risk patient.

"Burned out" testicular seminoma presenting as a primary gastric malignancy.

In contrast to primary gastric adenocarcinomas, germ cell tumors are potentially curable even when metastatic. It is therefore essential for clinicians and pathologists to be aware of the spectrum of unusual manifestations of germ cell malignancies. Here we report on a 55-year-old man who presented with clinical and endoscopic features indicative of a primary gastric carcinoma.

Anatomic considerations of the posterolateral lumbar disk region.

Sixteen embalmed cadavers were dissected to determine the location of the lumbar nerve root and sympathetic trunk with reference to the superior border of transverse process. In the posterolateral lumbar disk region, a safe zone was found between the anterior limit of the lumbar nerve and the posterior limit of the sympathetic trunk. It has a transverse dimension of 22 mm at the T12-L1 disk region and 25 mm at the L4-L5 disk region.
