Life-threatening hemorrhage due to cytomegalovirus infection of the gastrointestinal tract.

Cytomegalovirus infection of the gastrointestinal tract of normal hosts is very rare. On the other hand, this is a common cause of morbidity in immunocompromised hosts. Herein we describe the case of a 52-year-old male who underwent a gastrectomy due to a severe gastrointestinal hemorrhage. Histological examination showed the characteristic cytomegalovirus inclusion bodies. The diagnosis was confirmed with immunohistochemistry and his immune system revealed no abnormality. We believe that, although it is very rare, cytomegalovirus infection should be kept in mind for non-immunocompromised patients with upper gastrointestinal bleeding or multiple gastric ulcers.

Changes of CPK and CPK-MB levels after open and laparoscopic cholecystectomy.

According to the World Health Organization, an increased ratio (more than 6%) of CPK-MB to total CPK may indicate the diagnosis of an acute infarction. But false elevation of CPK and CPK-MB levels after noncardiac operation, because of soft tissue damage, may confuse the clinicians in detecting myocardial infarction in early postoperative period. In order to determine the usefulness of CPK-MB to total CPK ratio in detecting myocardial infarction after open and laparoscopic cholecystectomy, we measured the serum levels of these markers in 135 patients, immediately after the operation and for the next five days. Patients were divided into four groups according to type of surgical procedure, as follows: Group I: a right oblique subcostal (Kocher's) incision was performed in 29 patients, Group II: a right paramedian transrectal incision was performed in 52 patients, Group III: a vertical high midline incision was performed in 17 patients, Group IV: laparoscopic cholecystectomy was performed in 37 patients. Although we found increased levels of CPK and CPK-MB after all the types of cholecystectomy, but in any case the CPK-MB exceeded more than 6% of total serum CPK. Furthermore we noticed that the patients who underwent open cholecystectomy with right oblique subcostal incision had the most elevated CPK and CPK-MB levels comparing to the other types of cholecystectomy. In conclusion, tissue damage after elective cholecystectomy is minimal and CPK-MB to total CPK ratio is a secure marker in detection of myocardial infarction during early post-operation period, after cholecystectomy.

Emphysematous cholecystitis. Review of five cases and report of septic musculoskeletal complications.

A variant of acute cholecystitis is emphysematous cholecystitis. Here in we reviewed useful clinical data of five cases of this entity. Clinical outcomes were uncomplicated for three patients who were treated with open cholecystectomy. But on the other hand we faced two septic musculoskeletal complications in two patients who were treated with percutaneous trans gallbladder drainage. We believe that we must be aware of musculoskeletal complications, whenever a patient with emphysematous cholecystitis is treated with percutaneous trans gallbladder drainage.

Pancreatic abscess due to perforation of duodenal diverticulum.

Duodenal diverticula are usually incidental findings, but some times could be complicated with inflammatory or pressures effects to pancreas tissue. We present a rare case of pancreatic abscess caused by a perforated diverticulum, arising from the distal end of the second part of the duodenum.
