Although this roundworm is common in pediatric practice, most doctors are unaware that it can cause appendicular colic with/or appendicitis, severe urogenital complications, bowel perforation, and peritonitis. We report a case of a young male who presented with signs and symptoms of acute peritonitis. Dur-ing the operation, perforation of the jejunum with a purulent exudate under the transverse colon, a left lateral canal, a Douglas cavity were found as well as single enlarged mesenteric lymph nodes. Histological studies detected Enterobius vermicularis in the lumen of the appendix and jejunum, as well as in the purulent exudate in the intestinal wall and serosa. A mesenteric lymph node, histologically presented with chronic nonspecific lymphadenitis. In conclusion, infection with Enterobius vermicularis should be considered in peri-tonitis, appendicitis, and enlarged mesenteric lymph nodes, especially in young patients.Hemolytic anemia is an uncommon complication after mitral valve repair. We present a case of a 55-year-old man who presented with post-operative hemolytic anemia after mitral valve repair with prosthetic ring. The hemolytic anemia improved after the patient had the prosthetic ring removed and the valve replaced by a prosthetic mitral valve. However, the post-operative course of the redo operation was complicated by acute renal failure and respiratory dysfunction, but the hemolytic anemia was finally abolished and the patient was discharged 20 days post-operatively in good condition.We report a case of a patient with a relapse of neuromyelitis optica. The relapse was initially treated with intravenous corticosteroids. A therapy with intravenous gamma globulin was started as there was no symptomatic improvement. The patient responded well to the treatment with no significant side effects. Worldwid
