The 'problem' radical hysterectomy.

This is a study of 243 radical hysterectomy and pelvic lymphadenectomy procedures performed for gynecologic malignancy. The term 'problem' radical hysterectomy was applied to those patients with one of the following conditions: (1) recent cervical conization (within 21 days). (2) previous total or supravaginal hysterectomy, (3) pregnancy, or (4) previous pelvic radiation. There were 88 patients in theses categories. One hundred and fifty-five patients had none of these predisposing problems which might influence operative or postoperative complications. There were two deaths (0.82 per cent). There was no statistically significant difference in operative injuries to the bladder, ureters, or rectum or in the mean operative time and mean blood loss across the categories. However, there was a statistically significant difference across the categories in postoperative complicatons, both major and minor. The greatest incidence of such complications occurred in patients who had previous radiation therapy and the second greatest incidence was in patients who had recent cervical conization. Pregnant patients had the least number of complications.

Intralymphatic injection of BCG into rhesus monkeys.

Since the route of administration of BCG may have an important function in immunotherapy, we investigated intralymphatic administration to direct BCG to the lymph nodes. Multiple injections of high doses of BCG were administered to 6 rhesus monkeys via the dorsal lymphatics of the lower limb. A suppurative lymphadenitis was observed along the lower limb and in the inguinal area in 5 of the 6 monkeys. However, many of the complications reported with other routes of administration were not observed. Granulomatous reactions and histiocytic responses developed in lymph nodes on the injected sides of the pelvis and distant nodes as well as in the liver. The intralymphatic route is the method by which high doses of nonspecific immunostimulants were delivered to regional lymph nodes. The efficacy of this approach remains to be established in tumor-bearing animals and humans.

Association between subjective sleep quality and depression on immunocompetence in low-income women at risk for cervical cancer.

OBJECTIVE: The purpose of this study was to investigate whether subjective sleep quality is more strongly associated with immunocompetence than depression among women at risk for cervical cancer. METHODS: Participants were 91 women referred for colposcopy because of abnormal results on a Pap smear. On the day of the procedure. participants completed the Center for Epidemiological Studies Depression Scale, two indices of subjective sleep quality (ie, satisfaction with sleep obtained and degree of sleep restfulness), and a health behaviors assessment questionnaire. Levels of peripheral blood lymphocyte subpopulations (helper T, cytotoxic/suppressor T, NK, and B cells) were also assessed at this time. Approximately 10 days later, the presence of depressive disorder was assessed using the Structured Clinical Interview for DSM-III-R. RESULTS: Hierarchical regression analyses revealed that satisfaction with the amount of sleep obtained was significantly associated with the circulating number and percentage of helper T cells (T(H)/CD4+) and the percentage of cytotoxic/suppressor T cells (T(C)/CD8+), after controlling for confounder variables (ie, age, smoking status, and drug use). Depression was significantly associated only with the percentage of T(C) cells. Sleep satisfaction remained significantly associated with the number and percentage of T(H) cells and percentage of T(C) cells after controlling for the variance explained by depression. CONCLUSIONS: Results of this study suggest that subjective sleep quality shares a significant and independent portion of the variance with immunity that is not accounted for by depression. Although the long-term impact of these immune alterations on disease progression needs to be directly explored, it may be important to systematically screen for and manage sleep disturbance in women at high risk for cervical cancer.
