In HIV-infected adults, oral ulcers occur more frequently, last longer and produce more painful symptoms than in immunocompetent people. Oral aphthous ulcers observed during the course of HIV infection may be severe and can result in significant morbidity in these patients. Such manifestations may interfere with oral functions and alter patients' quality of life. To evaluate the efficacy and side effects of topical agents used in the treatment of HIV-related oral aphthous ulcers in adults. The following electronic databases were searched from the year 1980 to May 2011 for randomised controlled trials involving managements of oral ulcers, apthouses in HIV infected adults: EMBASE, PUBMED, the Cochrane Central Register of Controlled Trials (CENTRAL). Only randomised controlled trials that evaluated the efficacy of any topical agent in treating HIV oral aphthous ulcerations in HIV positive adults were considered. Two authors independently assessed the potentially eligible studies for inclusion. We did not find any studies that meet our eligibility criteria. Therefore, no analysis was performed. A total of 233 abstracts were retrieved from the databases searched. None of the identified studies met our inclusion criteria. Ten of the studies identified were reports of systemic rather than topical treatment. Therefore, no studies were included in this review. There is a need for well designed studies to evaluate the efficacy and safety of topical agents for the treatment of HIV related oral aphthous ulcers. Source

In the face of scarcity of energy resources and rising energy prices due primarily to a world of increasing demand, energy security concerns becomes more crucial both for private and public sector alike. At the same time, energy policies have been shifting and policy changes have become hard to predict because of radical changes in energy supply. This paper analyzes the barriers to sustainable energy development in Nigeria which are: (1) cost and pricing barriers, (2) legal and regulatory barriers, (3) market performance barriers. It concludes by highlighting some key policies that can help address some of the identified barriers in order to ensure a secured sustainable energy future for Nigeria. © 2016 The Author.

The computer vision and a stereoscopy technique were used to characterize and detect changes in the capacity of the salmon fillet surface to recover its original form after a constant weight was applied. A curvature index (associated to fillet firmness) calculated by means of 3D information data obtained with the stereoscopy technique from the fat stripe on the fillets was estimated over 6 months and was suggested as a characteristic of the recovery property of the fresh salmon fillet surface. Simultaneously, instrumental firmness using a LFRA1500 texture was measured. The values for the fresh salmon fillet measurement curvature index during a period of 6 months were established in the range of 0.05 and 0.10 (dimensionless), and this value was used in the experiments to represent fresh salmon fillets. Changes in the curvature index (associated with similar changes in firmness) for salmon fillet surface treated with enzymes (pepsin and papain) were registered on the second day during storage at 2 °C. In general, stereoscopy is a technique that can be used on salmon fillets to detect changes in the recovery properties of the salmon fillet surface and to determine when salmon fillets can be classified as a fillet that has not been processed with enzymes. © 2008 Springer Science + Business Media, LLC.

Pneumonia, a common childhood infection in Nigerian children with a number of debilitating complications such as empyema thoracis, has been linked to vitamin D deficiency due to its ability to modulate the T lymphocyte of the immune system . To determine the relationship between vitamin D and outcome of pneumonia in children. This was a case-control study involving 24 children, admitted for pneumonia as subjects and 10 children without pneumonia as controls. Pre-formatted questionnaire was utilized to obtain background information, anthropometric measurements were made to determine nutritional status and estimation of 25- hydroxy cholecalciferol (25OHD) done for all those studied. The mean (SD) serum 25OHD concentration was 104 (59) nmol/L and 130 (107) nmol/L for subjects and controls respectively. Amongst the subjects 15 (54%) had serum 25OHD less than 70 nmol/L and 11 (46%) serum 25OHD greater than 70 nmol/L. Hypocalcaemia was present in 15 (54%) of the subjects. Further analysis of hypocalcaemia with regards to the concentration of serum 25OHD showed that 2 (13%) had levels below 40 nmol/L, 10 (67%) had levels below 70 nmol/L and 3 (20%) above 70 nmol/L. Hypocalcaemia was more frequent among subjects with 25OHD below 70nmol/L compared with those above 70nmol/L, (p =0.01). Empyema thoracis and death occurred amongst the two subjects with 25OHD between 27.5 and 40 nmol/L. Anaemia was more frequent among subjects with 25OHD below 70 nmol/L compared with those above 70 nmol/L (p = 0.03). The study showed that Vitamin D insufficiency, and not solely its deficiency, may have an important role to play in the immune and haemopoetic system. It may therefore affect the response of a child to infections especially pneumonia. Source

To present a 10year retrospective histologic study of prostate diseases in Lagos, Nigeria. The aim is to document the prevalence, histologic pattern, age distribution and PSA values of prostatic diseases. The materials consisted of slides, paraffin embedded tissue blocks, patients case files and histology request forms of all prostatic biopsies received at the Morbid Anatomy department of Lagos University Teaching Hospital Idi-Araba, Lagos from 1999 to 2008. Each sample represents a different patient. Prostatic biopsies comprised 3.6 % of all biopsies in LUTH. BPH was the commonest prostatic lesion and accounted for 70.9% of all cases. The age range was 40 to 94 years with a mean of 67 years and a peak age group at 60-69 years. Stromoglandular pattern was the most common histological type of BPH accounting for 72.2 %( 393) of the cases. Malignant tumours constituted 28.9% of all prostatic biopsies. Most (93.7%) of these malignancies were seen in trucut biopsies. Adenocarcinoma accounted for 99.1% of the total 222 malignant tumours. It showed an age range of 40 to 98 years, a mean age of 66 years and peak prevalence in the 60-69 year age group. Gleason score nine was the most frequent (16.8%) in occurrence. Most adenocarcinomas were poorly differentiated (40%). Incidental carcinoma was seen in 4.2% of prostatectomy samples. High grade PIN was seen in 19.1% of adenocarcinoma cases. The most common inflammatory lesion was chronic non-specific prostatitis accounting for 76.4% of all inflammatory lesions. Malignant and benign lesions were accountable for PSA levels of 1 to 49.9ng/ml while values of 50ng/ml and above were seen exclusively in malignant lesions. Prostatic lesions constitute a significant source of morbidity among adult males in Lagos. Adenocarcinoma is the commonest histologic subtype of prostatic cancer and most are of poorly differentiated variety. Elevated levels of tPSA in Nigerian males may be as a result prostate cancer, BPH or BPH with prostatitis. PSA should in our opinion be used as a component of a strategy integrating multiple diagnostic approaches for prostate cancer screening and not to be used alone in our environment. Source
