Clonorchiasis-associated perforated eosinophilic cholecystitis.

Clonorchiasis, a disease caused by infection with Clonorchis sinensis, is endemic in the Far East. Cholelithiasis, pyogenic cholangitis, cholecystitis, and biliary tract obstruction are common complications of chronic infection. Although cholecystitis caused by clonorchiasis is common, it is rarely reported as resulting from eosinophilic infiltration. We report a rare case of clonorchiasis-associated perforated eosinophilic cholecystitis and review the relevant literature.

Acute acalculous cholecystitis in a child with Plasmodium falciparum malaria.

We report a 7-year-old girl who presented with features of acute acalculous cholecystitis. She was found to be positive for Plasmodium falciparum. To the best of our knowledge, this is the first report of acalculous cholecystitis caused by P. falciparum in a child.

Roundworm infestation presenting as acute abdomen in four cases--sonographic diagnosis.

Infestation with Ascaris lumbricoides (roundworm) is very common in the tropics and subtropics. Patients with ascariasis can be asymptomatic or may present with different clinical features in the form of simple nausea, decreased appetite, abdominal pain or more severe bowel obstruction, perforation, intussusception, biliary colic etc. Ultrasonography (USG) can be quick, safe, noninvasive and relatively inexpensive tool in diagnosing the presence of worms and also evaluating response to treatment (1, 2, and 3). Here we present four cases of roundworm infestation presenting with acute abdomen in the emergency department, which were diagnosed by USG and further imaging features of ascariasis on USG is described.
