Clinical and microbiological profile of adult inpatients with community acquired pneumonia in Ilorin,North Central,Nigeria

BackgroundThe optimal management of community acquired pneumonia (CAP) depends on the clinical and microbiological profile in the locality.ObjectivesTo determine the clinical and microbiological profile of patients admitted with CAP in Ilorin, Nigeria.MethodsOne hundred and two consenting consecutively selected patients with clinical and radiologic confirmation of CAP were recruited in 12 months. The socio-demographic, physical examination and laboratory/radiologic parameters were documented in a questionnaire. Microbiological evaluation of their sputum was done and blood samples were taken for complete blood count, culture, serum urea and serological evaluation for atypical bacteria and some viral pathogens.ResultsCAP constituted 5.9% of the total medical admissions during the one-year study period. The mean age of the patients was 49 ± 22 years with the largest frequency in those aged 65 years and above. The commonest symptoms were shortness of breath (96.1%) and cough (94.1%), with a median duration of 3 days from symptom onset to admission. Systemic hypertension was the commonest comorbid illness (25/102; 24.5%). Klebsiella pneumoniae was the predominant pathogen isolated (20/102; 28.1%). The susceptible antibiotics were Imipenem, Ceftazidime and Ceftriaxone. Intra-hospital mortality was 17.6%. CURB – 65 score of ≥ 2 and the presence of complications of CAP were the independent predictors of mortality.ConclusionCAP constitutes a significant disease burden in Ilorin, Nigeria. Typical bacteria accounted for over half of the pathogens isolated from the patients with gram negative agents predominating. This highlights a possible shift in the microbiological profile which could guide empirical treatment.     

Reference values of oxidative stress parameters (MDA, SOD, CAT) in dogs and cats

The present study was performed on 56 clinically healthy dogs and 52 clinically healthy cats, age and sex matched. The reference values of principal parameters of oxidative stress—malondialdehyde (MDA), superoxide dismutase (SOD), and catalase (CAT)—were determined in blood samples of dogs and cats. It was found that MDA plasma concentrations in male dogs were higher than those in females. The same difference was found in cats but the sex difference was much higher. SOD activity did not show any sex differences in dogs or cats. The CAT values were lower in males compared to females in only cats .     

The effect of Hepatitis D co-infection on the immunologic and molecular profile of Hepatitis B in asymptomatic Chronic Hepatitis B patients in southwest Nigeria

ABSTRACT

Introduction: Hepatitis D infection causes severe form of viral hepatitis in humans and only affects those with hepatitis B either as a co-infection or superinfection. The aim of this study was to determine the prevalence of Hepatitis D and its effect on the immunologic and molecular profile of Hepatitis B among asymptomatic Chronic Hepatitis B patients in Abeokuta.

Methodology: A cross-sectional study of 99 chronic HBV patient who met the inclusion criteria. All the patients were tested for HBsAg, anti HCV, HDV antigen, anti HDV, HBsAg quantification, and HBV DNA quantification. Associations were tested for and P value less than 0.05 was considered significant.

Results: The participants included 53 (58%) male and 38 (42%) females with ages ranging from 18 to 69 (means 39 ± 11) years. Ten (11%) participants were positive for HDV-Ag while 1 (1.1%) was positive for anti-HDV. Five (5.5%) were positive for HIV 1 &2 while 1 (1.1%) was positive for anti HCV. HBV DNA quantification ranged from 15 to 17,000,000 IU/ml while HBsAg quantification ranged from 0.25 to45,520 IU/ml. There was no statistically significant relationship between HDV-Ag and age (p = .51), sex (p = .73), HBV DNA (p = .8) and HBsAg quantification (p = 1).

Conclusion: The prevalence of HDV-Ag among asymptomatic treatment naïve chronic hepatitis B patients in Abeokuta was 11% and there was no significant difference in the levels of HBV DNA and HBsAg among those with or without hepatitis D.     

Reference ranges for haematology, biochemical profile and electrophoresis in a single herd of Ragusana donkeys from Sicily (Italy)

Donkeys, an endangered species, have recently gained a new application with the use of their milk to feed humans with allergic processes. The Ragusana donkey breed from Sicily is used to produce milk for humans with allergic diseases. In order to evaluate the hygienic, nutritional and management measures on a farm of Ragusana donkeys, complete blood counts, extended biochemical profiles and serum protein electrophoresis, as part of metabolic profile test (MPT), were performed in Ragusana donkeys. Fifty-four donkeys were studied and grouped according to their age, (1) 29 females and a single stallion (n=30), (2) young females, 1 – 3 years old (n=10) and (3) young of both sexes under 1 year old (n=14). The RBC count, RDW value, Lymp, and Mono counts, and PDW values were statistically greater in donkeys under one year old than in adult donkeys, while the Seg Neu count was lower. The CPK, ALP, iPhos, and HCO₃, values were statistically higher in the group of donkeys under 1 year of age than adult donkeys while Cl and LDH values were statistically lower in donkeys under 1 year than adult donkeys. Additionally, statistically significant increased values for CPK, ALP, Alb, Chol, iPhos, HCO₃, and UIBC in young donkeys under 1 year when compared with young donkeys, 1 – 3 years were observed. A statistically significant decreased value for Urea and an increased value for Crea in young donkeys, 1 – 3 years old were found as compared to adults. The serum protein fractions recognised by electrophoresis were: albumin, alpha globulin (subdivided into alpha-1 and alpha-2-globulins), beta globulin, and gamma globulin. In the alpha-1-globulin region three small peaks were constantly noticed, and alpha-2-globulins were statistically different between the three groups being greater in young donkeys under 1 year of age. The results obtained were used both to establish reference ranges and a data bank for the farm of Ragusana donkeys for future needs in assessing the metabolic status and health of the animals.     

The Need for Enhancement of Research, Development, and Commercialization of Natural Medicinal Products in Nigeria: Lessons from the Malaysian Experience

The use of natural medicinal products in modern medicine as complementary and alternative therapies is of the increase globally. More so in developing and third world countries where the cost of research and development of synthetic drugs is prohibitive and technological facilities as well as expertise are lacking. These, coupled with the crumbling health care management systems in many of such countries make herbal medicines attractive alternatives. The potential medicinal values of these plant products are not being properly harnessed and research and development (R&D) in this area are lagging behind. R&D and consultancy services span from phytochemical analysis, standardization and quality control of herbs, and dosage forms design to preclinical and clinical trials. This paper tries to highlight all the necessary steps needed to conduct research and development in this area and proposes the nitty - gritty needed to impose statutory regulations on ensuring the quality, safety, efficacy, and commercial distribution of such products. The paper examines these important issues and highlights by way of examples, some of the steps taken and the positive achievements of the people and government of Malaysia towards self reliance in the area of natural medicinal plant research. It is primarily intended to map out strategies on how Nigeria in conjunction with research and academic institutions can be actively involved in natural products R&D, taking the Malaysian experience as a prototype. It is also aimed at urging government''s efforts to encourage research in this area and impose regulations for commercial production and distribution of such products.

Evaluation of a Safer Male Circumcision Training Programme for Traditional Surgeons and Nurses in the Eastern Cape, South Africa

Training designed to improve circumcision knowledge, attitude and practice was delivered over 5 days to 34 traditional surgeons and 49 traditional nurses in the Eastern Cape, South Africa. Training included the following topics: initiation rites; statutory regulation of traditional male circumcision and initiation into Manhood (TCIM); structure and function of the male sex organs; procedure of safe circumcision, infection control; sexually transmitted infections (STIs); HIV/AIDS; infection control measures; aftercare of the initiate including after care of the circumcision wound and initiate as a whole; detection and early management of common complications of circumcision; nutrition and fluid management; code of conduct and ethics; and sexual health education. The evaluation of the training consisted of a prospective assessment of knowledge and attitude immediately prior to and after training. Significant improvement in knowledge and/or attitudes was observed in legal aspects, STI, HIV and environmental aspects, attitudes in terms of improved collaboration with biomedical health care providers, normal and abnormal anatomy and physiology, sexually transmitted infections and including HIV, circumcision practice and aftercare of initiates. We concluded that safer circumcision training can be successfully delivered to traditional surgeons and nurses.     

Reference values for volume,fat content and shape of the hip abductor muscles in healthy individuals from Dixon MRI

Healthy hip abductor muscles are a good indicator of a healthy hip and an active lifestyle, as they are greatly involved in human daily activities. Fatty infiltration and muscle atrophy are associated with loss of strength, loss of mobility and hip disease. However, these variables have not been widely studied in this muscle group. We aimed to characterize the hip abductor muscles in a group of healthy individuals to establish reference values for volume, intramuscular fat content and shape of this muscle group. To achieve this, we executed a cross-sectional study using Dixon MRI scans of 51 healthy subjects. We used an automated segmentation method to label GMAX, GMED, GMIN and TFL muscles, measured normalized volume (NV) using lean body mass, fat fraction (FF) and lean muscle volume for each subject and computed non-parametric statistics for each variable grouped by sex and age. We measured these variables for each axial slice and created cross-sectional area and FF axial profiles for each muscle. Finally, we generated sex-specific atlases with FF statistical images. We measured median (IQR) NV values of 12.6 (10.8-13.8), 6.3 (5.6-6.7), 1.6 (1.4-1.7) and 0.8 (0.6-1.0) cm³/kg for GMAX, GMED, GMIN and TFL, and median (IQR) FF values of 12.3 (10.1-15.9)%, 9.8 (8.6-11.2)%, 10.0 (9.0-12.0)% and 10.2 (7.8-13.5)% respectively. FF values were significantly higher for females for the four muscles (p < 0.01), but there were no significant differences between the two age groups. When comparing individual muscles, we observed a significantly higher FF in GMAX than in the other muscles. The reported novel reference values and axial profiles for volume and FF of the hip abductors, together with male and female atlases, are tools that could potentially help to quantify and detect early the deteriorating effects of hip disease or sarcopenia.     

Expansion of Genetic Testing in the Division of Functional Genomics,Research Center for Bioscience and Technology,Tottori University from 2000 to 2013

Background

At the Division of Functional Genomics, Research Center for Bioscience and Technology, Tottori University, we have been making an effort to establish a genetic testing facility that can provide the same screening procedures conducted worldwide.

Methods

Direct Sequencing of PCR products is the main method to detect point mutations, small deletions and insertions. Multiplex Ligation-dependent Probe Amplification (MLPA) was used to detect large deletions or insertions. Expansion of the repeat was analyzed for triplet repeat diseases. Original primers were constructed for 41 diseases when the reported primers failed to amplify the gene. Prediction of functional effects of human nsSNPs (PolyPhen) was used for evaluation of novel mutations.

Results

From January 2000 to September 2013, a total of 1,006 DNA samples were subjected to genetic testing in the Division of Functional Genomics, Research Center for Bioscience and Technology, Tottori University. The hospitals that requested genetic testing were located in 43 prefectures in Japan and in 11 foreign countries. The genetic testing covered 62 diseases, and mutations were detected in 287 out of 1,006 with an average mutation detection rate of 24.7%. There were 77 samples for prenatal diagnosis. The number of samples has rapidly increased since 2010.

Conclusion

In 2013, the next-generation sequencers were introduced in our facility and are expected to provide more comprehensive genetic testing in the near future. Nowadays, genetic testing is a popular and powerful tool for diagnosis of many genetic diseases. Our genetic testing should be further expanded in the future.
