Surgical correction of a rare variant of cor triatriatum.

Cor triatratum is a rare congenital malformation. Problems in diagnosis and surgery arise due to associated anomalies such as atrial septal defects and anomalous pulmonary venous drainage. A 21-year-old man proved to have a rare variant of cor triatiatum in which both the upper and lower compartments of the left atrium communicated with the right atrium through two separate atrial septal defects. In addition, he had anomalous drainage of the right superior pulmonary vein into the superior vena cava. Intracardiac repair was undertaken successfully.

The psychosocial context of Black women's health.

Researchers have demonstrated that Black women exhibit a disproportionate risk of ill health. We examined the relationship between psychosocial factors, including economic status, race-based social inequality, gender-based violence, and the health status of 323 Black women between the ages of 18 and 65. Black women from a community sample completed a health survey with open-ended responses. Results indicated that women in lower economic groups are more likely to be treated for allergies (p = < .05) and pelvic inflammatory disease (PID; p = < .01). Women who experienced increased incidents of race-based social inequality received more medical treatments for yeast infections, pregnancy-related problems, allergies, and PID. Those with histories of physical, psychological, and early sexual abuse are more likely to be treated for depression, allergies, yeast infections, and hypertension. In addition, qualitative data examined the process in which economic, race-based social inequality, and gender-based violence contributed to the ill health of Black women. The implications of these findings suggest that understanding the psychosocial context is essential for appropriate clinical practice. Additionally, future research should conceptualize health as a complex interaction of psychosocial risks that have a profound effect on the health status of Black women.

High-risk human papillomavirus, tumor suppressor protein p53 and mitomycin-C in invasive squamous cell carcinoma cervix.

BACKGROUND: Clinical data relating to human papillomavirus (HPV) infection and p53 status in cervical cancer has been sparse and confusing. AIM: To evaluate high-risk HPV and expression of tumor suppressor protein p53 in squamous cell carcinoma of cervix and to assess response to mitomycin-C in neo-adjuvant chemotherapy. SETTING AND DESIGN: Teaching College Hospital; Gynecologic Oncology Unit and Department of Pathology. Prospective, randomized. MATERIALS AND METHODS: Expression of p53 protein was assessed, using immunohistochemistry with mouse monoclonal antibody in 30 consecutive patients undergoing radical hysterectomy or admitted for neo-adjuvant chemotherapy. Human papillomavirus DNA (HPV DNA) was assessed using hybrid capture II technology. Patients eligible for chemotherapy were randomized into vincristine, bleomycin and cisplatin (VBP) group and VBP with mitomycin C group. STATISTICAL ANALYSIS: Chi-square test, one-way ANOVA, Pearson's correlation; Mann-Whitney, McNemar and Fischer's exact tests were used for statistical analysis. RESULTS: All patients with cancer cervix were positive for high-risk HPV DNA having relative light units/cut off values ranging from 3.4-2389.21 (P value = 0.006). High viral load of high risk HPV DNA was seen in advanced stages (P = 0.05) and an association of viral load with tumor volume was also seen (r = 0.361, P = 0.05). Analysis of p53 protein in cervical carcinoma patient showed expression in 50% of cancer specimens (P value < 0.001). McNemar's and Fischer's exact test showed no change in p53 status post-chemotherapy; however 66% of stage II B patients in VBP-M group became operable. CONCLUSION: High-risk HPV was universally present in all cases of cancer cervix and viral load was associated with stage and tumor volume while p53 protein was expressed in 50% of cases suggesting deregulation. More studies using mitomycin-C in cervical cancer treatment protocols are needed.

Autologous fibrin adhesive in experimental tubal anastomosis.

OBJECTIVE: To evaluate autologous fibrin in rabbit oviduct anastomosis versus 7-0 vikryl, a conventional suture material used in tubal anastomosis. METHODS: Thrombin was added to the autologous fibrinogen at the site of anastomosis to obtain a tissue adhesive. The anastomotic time, pregnancy rate, and litter size were evaluated. Three months later, a relaparotomy was done to evaluate patency and degree of adhesions, and a tubal biopsy was taken from the site of anastomosis. RESULTS: Analysis of results showed a statistically significant (P < .001) shortened anastomotic time and superior histopathological union in the tissue adhesive group. Patency rate, pregnancy rate, and degree of adhesions were comparable in both groups.
