Evaluation of Direct Visual Inspection of the Cervix in Detecting Cytology Diagnosed Squamous Intraepithelial Lesion in Women of known HIV Status. A Randomized Trial (CANHIV Study).

A two-arm, open label, randomized study, evaluated the test characteristics of visual inspection of cervix with Acetic acid(VIA) and Lugol?s Iodine(VILI) in detecting cytology diagnosed squamous intraepithelial lesion(SIL) in 1160 women of known HIV status in southwestern Nigerian. Using SIL as reference standard and the HIV status masked, VIA and VILI had similar test characteristics except for the positive predictive value in which VIA value of 91.5% was significantly higher than 77.7% for VILI ( p=0.01). Among HIV positive women, VILI performed poorly across all the 4 test characteristics compared to VIA. Among severely immuno-compromised HIV positive participants VILI performance was consistently below 80% across all test characteristics (sensitivity-70.0%; specificity-66.9%; positive predictive value-46.7%; negative predictive value(NPV)-50.0%) compared to VIA (Senstivity-71.3%; specificity-88.2%; positive predictive value-83.3%; negative predictive value -88.2). Our study shows that VILI is insufficiently sensitive and specific in the presence of HIV infection especially in those with severe immunosuppression. Based on VIA?s acceptable sensitivity and NPV in all situations, it is recommended for cervical cancer screening in HIV positive women and in settings of high HIV burden.

Multiple myeloma in Nigeria: a multi-centre epidemiological and biomedical study.

INTRODUCTION: Myelomatosis is a malignant proliferation of plasma cells in the bone marrow, with relatively high prevalence in African populations. Variation in genetic mutations has been observed in individual patients and may be responsible for differences in disease pattern and treatment outcomes. This study described the presentations and treatment outcomes of multiple myeloma in nigerian. METHODS: The data was obtained retrospectively from the case notes of 135 patients diagnosed with multiple myeloma from eight tertiary health institutions across the six geopolitical zones of Nigeria from 2005 to 2014. Data analysis was carried out using SPSS 17.0. RESULTS: The predominant presentations were bone pain in 97 (74%), nephropathy in 47 (35.9%) and pathological fractures in 58 (44.3%). Sixty-seven percent (67%) of the patients were less than 60 years, and 35% had Bence Jones proteinuria. The overall survival beyond 6 months was 91.3%, mean duration of survival rate was 7.4 months. Majority (66.2%) were on Melphalan alone or on melphalan-containing combinations. A higher packed cell volume (PCV) and total serum protein levels at presentation were associated with increased survival, p=0.033 and 0.036, respectively. CONCLUSION: This study portrayed the importance of detail investigation on the causes of bone pain and anaemia in person's aged 40 years and above. There is a high prevalence of nephropathy in this cohort of patients which needs to be further investigated. Majority of the patients, though < 65 years of age were placed on melphalan-containing combinations, which foreclosed chances of future autologous bone marrow transplantation.
