Early detection of dental caries is critical for avoiding more invasive and advanced treatment at a later stage. However, currently available techniques are unsatisfactory for early detection. Raman spectroscopy is known to have both high sensitivity and specificity in the analysis of mineral content in a tooth; but translating Raman spectroscopy to clinical caries detection remains a challenge. In this study, we report a full-scale Raman imaging system that can provide fast full-scale (~7 mm in diameter) tooth mineral analysis which could be feasible for clinical application. The results show that the Raman imaging system could not only confirm carious lesions that are obvious to the naked eye but also identify those which are not conclusive to traditional visual examination and probing.

BackgroundPelvic organ prolapse (POP) is the herniation of pelvic organs from its anatomical confines, and it is of considerable importance to the practicing gynaecologist in middle and low income countries. It is commonly associated with, urinary tract infection (UTI), both symptomatic and asymptomatic due to anatomical and physiological changes. The aim of this study was to determine the prevalence of asymptomatic bacteriuria among women with pelvic organ prolapse, to know the organisms commonly implicated and the sensitivity pattern.MethodsThis study was conducted among 96 women with POP at the National Obstetric Fistula Centre Abakaliki. A cross sectional descriptive study was done. Standard microbial technique was used to analyze the urine. Data was analysed using the Statistical Package for Social Sciences version 17.ResultsOut of the 96 patients, 76 were found to have asymptomatic bacteriuria giving a prevalence of 79.2%. Nine different bacteria species isolated include E. Coli (34.2%), Streptococcus pneumonia (23.7%), Staphylococcus aureus (7.9%), Proteus Spp (7.9%) others (5.3%). The highest level of microbial sensitivity to the antimicrobials was with Ciprofloxacin.ConclusionsThis study suggests that prevalence of asymptomatic bacteriuria is very high among women with POP. More than 50% of the bacterial isolates were mainly E.coli and Streptococcus pneumonia. The highest level of microbial sensitivity was with ciprofloxacin while the least was with cotrimoxazole.

The success rate was good. Patients who had previous failed repairs at the fistula centre had better outcomes after the repeat surgeries. Centralizing fistula care will enhance optimal outcomes. It may also boost training and research in this specialty.

Background: Neurofibromatosis type 1 is an autosomal dominant transmitted disease with various forms of clinical presentation. It commonly affects the skin and the nervous system. Involvement of the genitourinary system is rare. The bladder is the most commonly affected organ in the urinary system. Vesicovaginal fistula presenting as continuous leakage of urine per vagina is a rare urogenital manifestation of neurofibromatosis which has not been previously reported to the best of our knowledge. Vesicovaginal fistula is not a usual complication of urethral catheterization. Our aim is to report a rare case of vesicovaginal fistula in a patient with neurofibromatosis.
