Cytomegalovirus infection and postoperative complications in patients with ulcerative colitis undergoing colectomy

Background. Ulcerative colitis (UC) can be complicated by reactivation of cytomegalovirus (CMV). CMV reactivation may change the course of UC and may require antiviral treatment. Some risk factors of CMV reactivation have previously been identified, whereas the association between CMV reactivation and postoperative complications has not been examined systematically. Methods. Patients with UC operated with colectomy due to active UC were studied (n = 77). Patient and disease characteristics, as well as postoperative complications were recorded and CMV was detected by immunohistochemical examination of multiple sections from the colectomy specimen. Results. CMV was found in nine (11.7%) colectomy specimens. CMV-positive patients received significantly higher doses of corticosteroids at colectomy than CMV-negative patients (61.1 ± 23 vs 32.5 ± 32 mg/day, p = 0.01). CMV-positive patients were also older, had a higher risk of severe complications, higher American Society of Anesthesiologists (ASA) score, longer preoperative stay, and a higher rate of acute surgery. Complications occurred in 30 (39%) patients after surgery, 8(10.4%) of whom were serious. Two CMV-positive patients (2.6%) died in-hospital after the colectomy. High ASA score was associated with the occurrence of serious complications. Conclusion. A relatively small proportion of patients with UC operated by colectomy were CMV positive. CMV positivity was associated with old age, high dose of corticosteroids at operation, high ASA score, acute surgery, and severe postoperative complications. Patients with such characteristics may be at risk of CMV infection and may require special management.

Multiple focal nodular hyperplasia, an incidental finding on autopsy.

Focal nodular hyperplasia (FNH) is a benign condition of the liver often discovered incidentally on radiological investigation. Although FNH is a well-described lesion in the literature considerable diagnostic problems regarding this entity still remains. We report a case of multiple FNH in a 23-year-old male patient detected as an incidental finding in autopsy. On gross examination FNH was not suspected because of the multiple lesions and the lack of central scar which is characteristically described in FNH. The diagnosis was established on histopathology after examination of multiple sections of the lesions.

A morphological study on the effect of cyproterone acetate on human prostatic carcinoma.

Sixteen patients with prostatic carcinoma were treated with 200 mg of Cyproterone acetate daily. No other kind of hormonal treatment was given. Transrectal biopsies of the prostate were taken before the treatment was started, and at regular intervals afterwards. The treatment period lasted from 3 to 16 months, with an average of 9 months. A thorough examination of multiple sections from all specimens revealed no convincing signs of cellular involution. The study has demonstrated no specific or significant atrophic changes following Cyproterone acetate therapy. Some possible explanations regarding the effect of Cyproterone acetate on human malignant prostatic tissue are discussed.
