We describe two neoplasms of rare occurrence, one of ovarian and the other of uterine origin that were sent for consultation. Both lesions were diagnosed as metastatic carcinomas by pathologists with special interest in gynaecological pathology. The cases were referred for a second opinion because of subsequent failure to identify the primary source. We discuss the differential diagnoses, the need for generous sampling particularly in ovarian mucinous neoplasms and the value of including particular antibodies in the panel to aid the diagnostic process. Metastatic tumours mimicking primary tumours are always challenging. These two cases illustrate the need to be vigilant against the reverse scenario as well.

Malignant transformation of a uterine leiomyoma is an exceedingly rare phenomenon. Previous reported examples of malignant neoplasms to arise so include leiomyosarcoma, angiosarcoma, and malignant mesenchymoma. We report an intramural carcinosarcoma arising in a uterine leiomyoma in a 38-year-old woman. This case is unique in being the first recorded carcinosarcoma arising within a uterine leiomyoma and the first example of an epithelial neoplasm to do so. We discuss the differential diagnosis and possible pathogenesis of the tumor that has likely arisen secondary to epitheliogenesis in a mesenchymal neoplasm.

Background. Nevirapine (NVP) can be safely and effectively administered once-daily but has not been assessed in human immunodeficiency virus (HIV)-infected patients with tuberculosis (TB). We studied the safety and efficacy of once-daily NVP, compared with efavirenz (EFV; standard therapy); both drugs were administered in combination with 2 nucleoside reverse-transcriptase inhibitors. Methods. An open-label, noninferiority, randomized controlled clinical trial was conducted at 3 sites in southern India. HIV-infected patients with TB were treated with a standard short-course anti-TB regimen (2EHRZ(3)/4RH(3);[2 months of Ethambutol, Isoniazid, Rifampicin, Pyrazinamide / 4 months of Isoniazid and Rifampicin] thrice weekly) and randomized to receive once-daily EFV at a dose of 600 mg or NVP at a dose of 400 mg (after 14 days of 200 mg administered once daily) with didanosine 250/400 mg and lamivudine 300 mg after 2 months. Sputum smears and mycobacterial cultures were performed every month. CD4+ cell count, viral load, and liver function test results were monitored periodically. Primary outcome was a composite of death, virological failure, default, or serious adverse event (SAE) at 24 weeks. Both intent-to-treat and per protocol analyses were done, and planned interim analyses were performed. Results. A total of 116 patients (75%[87 patients] of whom had pulmonary TB), with a mean age of 36 years, a median CD4+ cell count of 84 cells/mm(3), and a median viral load of 310 000 copies/mL, were randomized. At 24 weeks, 50 of 59 patients in the EFV group and 37 of 57 patients in the NVP group had virological suppression (P =.024). There were no deaths, 1 SAE, and 5 treatment failures in the EFV arm, compared with 5 deaths, 2 SAEs, and 10 treatment failures in the NVP arm. The trial was halted by the data and safety monitoring board at the second interim analysis. Favorable TB treatment outcomes were observed in 93% of the patients in the EFV arm and 84% of the patients in the NVP arm (P =.058). Conclusions. Compared with a regimen of didanosine, lamivudine, and EFV, a regimen of once-daily didanosine, lamivudine, and NVP was inferior and was associated with more frequent virologic failure and death.

BACKGROUND Our aim was to study the incidence and pattern of dyslipidemia among human immunodeficiency virus (HIV)-infected patients with tuberculosis (TB) who received once-daily antiretroviral therapy (ART). METHODS Antiretroviral-naive HIV-infected patients with TB were recruited to a trial of once-daily nonnucleoside reverse-transcriptase inhibitor (NNRTI)-based ART and treated with rifampicin-based thrice-weekly antituberculosis treatment (ATT); participants were randomized to receive didanosine (250/400 mg) and lamivudine (300 mg) with either efavirenz (600 mg) or nevirapine (400 mg) once-daily after an intensive phase of ATT. Fasting triglyceride (TG) level, total cholesterol (TC) level, low-density cholesterol (LDL-c) level and high-density cholesterol (HDL-c) level were measured at baseline and at 6 and 12 months. Lipid levels at 6 and 12 months were compared with baseline values with use of repeated measures analyses. McNemar test was used to compare the proportion of patients with lipid abnormality at baseline versus at 12 months, and χ² test was used to compare between the 2 groups. RESULTS Of 168 patients (79% men; mean age, 36 years; mean weight, 42 kg; median CD4+ cell count, 93 cells/mm³), 104 received efavirenz-based ART, and 64 received nevirapine-based ART. After 6 months, TC levels increased by 49 mg/dL, LDL-c levels by 30 mg/dL, and HDL-c levels increased by 18 mg/dL (P <.001 for all). At baseline and at 12 months, TC was >200 mg/dL for 1% and 26% of patients, respectively; LDL-c level was >130 mg/dL for 3% and 23%, respectively; HDL-c level was <40 mg/dL for 91% and 23%, respectively; and blood glucose level was >110 mg/dL for 14% and 13%, respectively. TC level >200 mg/dL was more common among patients who received efavirenz than among those who received nevirapine (32% vs 16%; P =.04). CONCLUSIONS HIV-infected patients with TB who initiate NNRTI-based ART undergo complex changes in lipid profile, highlighting the importance of screening and treating other cardiovascular disease risk factors in this population.

BACKGROUND: Tuberculosis occurs in 60%-70% of HIV-positive persons in India. The outcome of HIV-positive patients treated with 6-month intermittent short course antituberculosis regimens in India is not well described. METHODS: This was a prospective observational feasibility study of 71 patients with HIV and tuberculosis who were treated with category I regimen of the Revised National Tuberculosis Control Programme (ethambutol, isoniazid, rifampicin and pyrazinamide thrice weekly for the initial 2 months followed by rifampicin and isoniazid thrice weekly for the next 4 months). Sputum was examined by smear and culture for Mycobacterium tuberculosis every month up to 24 months. Chest X-ray, CD4 cell count and viral load were done prior to and at the end of treatment. None of the patients received antiretroviral therapy. RESULTS: We present here the treatment response of patients with sputum culture-positive pulmonary tuberculosis to category I regimen. By efficacy analysis, among 43 patients treated with category I regimen, sputum smear conversion was observed in 79% and culture conversion in 82% at the second month. A favourable response was seen in 72% of patients. The mean (SD) CD4% fell from 12.6 (5.9) to 8.9 (4.9)(p < 0.001) with no significant change in mean (SD) CD4 cell count (169 [126] to 174 [158]; ns) at the end of treatment. Viral load change from 1.8 x 10(5) at baseline to 1.3 x 10(5) at the end of treatment was not statistically significant. Thirty-one patients, who completed the full course of treatment, were declared cured and were followed up for 24 months. Twelve had recurrent tuberculosis (39%); 16 of 43 (37%) patients had died by the end of 24 months, two-thirds due to causes other than tuberculosis. CONCLUSION: Though the early bacteriological response to intermittent short course antituberculosis regimen was satisfactory, the overall outcome was adversely affected by the high mortality (during and after completion of treatment) and recurrence rate among HIV-infected patients with tuberculosis. Immune status deteriorated in spite of antituberculosis treatment, highlighting the need for antiretroviral treatment in addition to antituberculosis treatment to improve the long term outcome. The results of this pilot study need to be confirmed by larger studies.

BACKGROUND: Women with polycystic ovary syndrome (PCOS) are assumed to be at increased risk of endometrial cancer (EC), albeit of a more differentiated type with better prognosis than in normal women. This study was designed to test these assumptions, as evidence for them is lacking. METHODS: The prevalence of polycystic ovaries (PCO), as a marker of PCOS, was investigated in ovarian sections from 128 women with EC and 83 with benign gynaecological conditions. The expression of the prognostic markers p53, Ki67, Bcl2 and cyclin D1 was also investigated by immunohisto-chemistry in endometrial tumours from 11 women with PCO and 16 with normal ovaries. RESULTS: Overall, PCO were similarly prevalent in women with EC (8.6%) and benign controls (8.4%); however, in women aged <50 years, PCO were more prevalent in women with EC (62.5 versus 27.3%, P = 0.033). Cyclin D1-expressing endometrial tumours tended to be more prevalent in women with PCO compared to normal ovaries (36.4 versus 6.25%, respectively, P = 0.071). Bcl2-, p53- and Ki67-expressing tumours were similarly prevalent. CONCLUSIONS: The association between PCOS and EC appears confined to premenopausal women. The tendency for cyclin D1-expressing endometrial tumours to be more prevalent in women with PCO challenges the assumption that EC prognosis is improved in women with PCOS.
