Recurrence of renal cell carcinoma with extensive vena caval thrombus three years after radical nephrectomy

A 70-year-old man, who had undergone a radical nephrectomy for localized renal cell carcinoma (RCC) three years ago, was recently evaluated for shortness of breath. During his work-up, a transesophageal echocardiogram and magnetic resonance imaging indicated an extensive vena caval thrombus originating from the renal vein stump. Successful vena caval thrombectomy with cardiopulmonary bypass confirmed that the thrombus was comprised of RCC. This is a rare type of RCC recurrence with an unusual timing (3 years after a nephrectomy), alerting the importance of strict follow-up on all patients even after complete surgical excision of all suspected tumors.     

Effect of combined oral contraceptives on bone mineral density in pre and postmenopausal women

A retrospective urban-based cross-sectional study was done in the department of Pharmacology in collaboration with the department of Obs and Gynae of BSSMU, Dhaka, to define any relation between the OCP and BMD in pre and postmenopausal women. A total of 100 closely matched healthy women were selected non-randomly. The age range was 35-55 years. Among them 50 were controls or nonuser and 50 were case or users of OCP. They were further subdivided into pre and postmenopausal groups. Bone density of the 100 women was measured in distal radius and ulna by single photon Absorptiometry Bone Densitometer DTX-100. Statistically significant higher bone mineral density (BMD) was found in oral combined OCP users than non-users, both in pre and postmenopausal women. It can be concluded from this study that the most important non-contraceptive benefit of OCP may be positive effects on bone mass and thus reduced risk of postmenopausal osteoporosis and osteroporotic fracture.     

Health-seeking behavior of Karachi women with reproductive tract infections

To explore the contextual factors influencing health-seeking behavior of women in Karachi regarding reproductive tract infections, 18 women with reproductive tract infections from different clinics and community settings were identified and in-depth interviews were conducted. Physicians in our study diagnosed a woman to have lower reproductive tract infection if she complained of malodorous vaginal discharge with or without perineal itching; and to have pelvic inflammatory disease or upper reproductive tract infection if she had any two of the following complaints: malodorous vaginal discharge, menstrual irregularities, lower abdominal pain or dyspareunia. Women consulted a variety of healthcare providers in their pursuit for treatment, mainly allopathic doctors and hakims. The different treatments prescribed to women ranged from oral and intravaginal medications to various home remedies including refraining from specific foods. Causes of reproductive tract infections reported were "melting bones", consuming foods with perceived hot composition, poor personal hygiene and procedures like dilatation and curettage, delivery and induced abortions. None reported sexually transmitted diseases as the perceived cause of their problem. Interference with religious activities, sexual relationships or socializing was reported as consequences of reproductive tract infections, in addition to lower abdominal pain, menstrual irregularities, backache and kamzori (weakness). Pakistani women seek care for reproductive tract infections and visit a variety of providers, though causes and treatments offered are usually not related to sexually transmitted diseases. We therefore suggest training of healthcare providers for appropriate counseling and that treatment management protocols be advocated.     

Evaluation of downstaging in the detection of cervical neoplasia in Kolkata,India

Unaided visual inspection or "downstaging" has been suggested as a potential alternative method for cervical cancer screening in developing countries. Our study was designed to evaluate the accuracy of downstaging to detect cervical neoplasia in a low-resource setting. A total of 6,399 women aged 30-64 years were screened with downstaging by trained nonmedical health workers. Two thresholds were used to define positive downstaging: "low threshold" when any visible abnormality on the cervix was considered positive and "high threshold" when selected abnormalities such as bleeding on touch, bleeding erosion, hypertrophied oedematous cervix, congested stippled cervix and growth or ulcer constituted the positive test. All women underwent a colposcopy examination. Biopsies were directed when colposcopy revealed abnormal lesions. True disease status was defined as histologically proven moderate dysplasia and worse lesions. Since all the participants received a diagnostic (reference) investigation (biopsy and/or colposcopy), sensitivity, specificity and predictive values were estimated directly. Low- and high-threshold downstaging were positive in 1,585 (24.8%) and 460 (7.2%) women, respectively. The sensitivities of low- and high-threshold downstaging to detect high-grade precursors and invasive cancers were 48.9% and 31.9%, respectively. The specificities were 75.8% and 93.3%, respectively. These results indicate that downstaging is not suitable as an independent primary screening modality for cervical neoplasia.
