Comparison of Dermatophytes and Other Agents of Human Dermatitis between Males and Females in Jos, Plateau State, Nigeria
C Aleruchi, AA Makinde, T Louisa, D James, SJ Shaibu, AOI Emenike
African Journal of Clinical and Experimental Microbiology , 2012,
Abstract: Dermatophytes are a group of three genera of fungi namely Microsporum spp, Trichophyton spp and Epidermophyton spp that commonly cause infections of the skin, hair and nails due to their ability to utilize keratin in both man and animals. Dermatophytes and other agents of human dermatitis are believed to have gender predisposition because of the anatomical and physiological nature of these genders. A study was undertaken to compare the distribution of dermatophytes and other agents of human dermatitis in patients who visited the Dermatophilosis Research Laboratory, National Veterinary Research Institute, Vom, Plateau State of Nigeria. A total of 1551 patients were involved in this study from 2003 to 2007; 823 of whom were males and 728 females. Samples collected were skin scrapping, nails, hair and pus exudates. They were processed according to standard procedures. Nine hundred and thirty two (60%) were positive for dermatophytes and other agents. Sporothrix schenckii (138 (12.4%)), Aspergillus flavus (128 (11.5%)), and Trichophyton mentagrophytes (112 (10.1%)), Mucor sp (105 (9.5%)) were the most commonly isolated fungi. Aspergillus flavus occurred more in males (74 (6.7%)) while Sporothrix schenckii was more in females (71 (6.4%)). More isolation was made from the head in males (185 (19.8%)) while in females more isolation was made from their limbs (150 (16.1%)). Males generally were more affected with skin infections than females.

AA Makinde, LH Lombin, A Chuku, L Ta’ama, J Dalis, SJ Shaibu, EAO Irokanulo
Journal of Applied Sciences and Environmental Management , 2010,
Abstract: Five hundred and twenty human samples were collected from patients with dermatitis, who visited the Dermatophilosis research laboratory in Jos, Plateau State, Nigeria. This was in order to determine occupational predisposition to dermatophytes and other agents of human dermatitis. Samples collected were skin scrapping, nails, hair and pus exudates. They were processed according to standard procedure. Four hundred and thirty-three (83.3%) of the collected samples were positive for dermatophytes and other agents of dermatitis. The breakdown of the result along occupational categories were; Students (38.10%), Civil servants (31.64%), Self-employed (12.93%), Housewives (9.24%), Unemployed (4.16%) and Farmers (3.93%). The dermatophyte Trichophyton mentagrophytes had the highest frequency of occurrence in Civil servants (28), Students (26) House wives (8) and Unemployed (5). While Aspergillus niger had the highest frequency with the Farmers (4) and Self-employed (11). The students’ were noticed to be more predisposed to dermatophytes and other agents of dermatitis than any other category as a result of poor environmental hostel conditions that facilitate easy spread of infections and their unhealthy habit of sharing clothing and personal items. A vigorus public awareness on the risk involved in unhealthy and unhygienic habits could reduce the spread of these organisms. @JASEM J. Appl. Sci. Environ. Manage.

Flea Bite Dermatitis in a Herd of Dairy Calves in Vom Nigeria
SJ Shaibu, IL Oyetunde, LD Jwander, JT Tanko, LT Ikpa, JJ Adamu
Nigerian Veterinary Journal , 2011,
Abstract: Fleas are parasitic insects which are found all over the world. They are wingless insects 1.5-4.0mm long, have a laterally compressed body and are different from lice in they are flattened dorso-ventrally, and are covered with a hard, shiny coating, like an external skeleton, which helps them to move through an animal's fur. There are more than 2,200 species of fleas recognized worldwide (Anon, 2006). Adult fleas are usually red-brown in color and have three pairs of legs, the last pair being quite large and well-adapted for jumping. They have piercing and sucking mouth parts which are specially designed for injecting into a host and sucking blood. They feed on the blood of cats, dogs and other animals, including humans (Lyon, 1997; Kramer and Mencke, 2001). Flea infestation in cattle and other ruminants is rare; it has been more commonly reported in cats and dogs. Infestations of calves with Ctenocephalides felis felis have been reported in Israel (Yeruham et al.,1989), the USA (Dryden et al., 1993) , Japan (Otake et al., 1997) and Brazil (Araujo et al., 1998). Kraal et al. (2006), in a survey of flea infestation, reported the infestation of calves and other domestic animal species in Libya. They reported that of the 1861 fleas recovered, 1857 were Ctenocephalides felis strongylus and 4 were Pulex irritans. Yeruham and Braverman (2004) reported Seasonal allergic dermatitis in sheep associated with Ctenocephalides and Culicoides bites. Ctenocephalides felis felis is a flea of cats and dogs, which is responsible for skin irritation and anaemia (Dryden and Rust, 1994) and transmission of the tape worm Dipylidium caninum (Pugh, 1987). This flea can also infest other mammals including humans (Genchi, 1992).
Knowledge and attitudes of physicians relating to reporting of adverse drug reactions in Sokoto, north-western Nigeria
Bello Shaibu,Umar Muhammad
Annals of African Medicine , 2011,
Abstract: Background/Objectives : Adverse drug reactions (ADRs) are important causes of morbidities. Voluntary reporting of ADR is important in safety surveillance of medicines already in the market. This study was, therefore, conducted to appraise the current documentation of ADR in Sokoto, to analyze the extent to which clinicians appreciate factors that could affect reporting ADRs. Materials and Methods : Four hospitals within Sokoto metropolis were selected by convenient sampling. Pre-validated questionnaires containing questions on demographic and professional characteristics, and questions that evaluate attitudes as listed in the so-called "deadly sins" of Inman were self-administered by physicians. Data from respondents were analyzed by logistic regression. Results : Of 61 physicians interviewed, 43 (70.5%) had encountered potential ADRs in the 12 months before the study but only 3 (7.0%) of these were reported. Fifty eight (95.1%) of the respondents were not aware that an ADR reporting system was available in Sokoto but all the 3 respondents who were aware of the existence of a reporting system had reported an ADR. Generally, there was no significant relationship between demographic and professional attributes and scores obtained on each of the Inman′s attitude measured except that more experienced physicians tend to believe that ADRs are not impossible to identify and female physicians were more reluctant to engage representatives of pharmaceutical companies on ADRs related to their drugs. Additional attitudes that may influence ADRs reporting were identified. Conclusion : Adverse drug reactions are under-reported in Sokoto. Lack of physicians′ awareness of channels for reporting appears to be the major cause.
11-Beta-Hydroxylase Deficient Congenital Adrenal Hyperplasia in a Toddler: Clinical Presentation and Management Challenges in a Developing Country
AN Onyiriuka,M Shaibu
Journal of Nepal Paediatric Society , 2013, DOI: 10.3126/jnps.v33i1.6181
Abstract: This paper reported a case of an eighteen-month old Nigerian girl with 11-beta-hydroxylase-deficient congenital adrenal hyperplasia who presented with hypertension and heart failure. The hypertension resolved with steroid therapy. Her blood pressure has remained normal on maintenance prednisolone. The abnormal external genitalia was probably missed at the private hospital where the child was born as it was not mentioned to the parents before discharge on the second day of life. When the child presented at about the age of two months with an enlarged clitoris, she was referred to a paediatric surgeon in another private hospital. It would have been more appropriate to refer her to a paediatric endocrinologist in the nearest tertiary healthcare institution. This case highlights the importance of thorough physical examination of the external genitalia at birth and appropriate referral. The management challenges encountered in the care of this patient included lack of laboratory facilities for diagnosis and monitoring of therapy, non-availability of necessary drugs (oral hydrocortisone) and late presentation.

Ab-Initio Computations of Electronic, Transport, and Related Properties of Chromium Disilicide (CrSi2)  [PDF]
Shaibu Onuche Mathias, Yuriy Malozovsky, Lashounda Franklin, Diola Bagayoko
Journal of Modern Physics (JMP) , 2018, DOI: 10.4236/jmp.2018.914158
Abstract: We report results from ab-initio, self-consistent density functional theory (DFT) calculations of electronic, transport, and related properties of chromium disilicide (CrSi2) in the hexagonal C40 crystal structure. Our computations utilized the Ceperley and Alder local density approximation (LDA) potential and the linear combination of atomic orbitals (LCAO) formalism. As required by the second DFT theorem, our calculations minimized the occupied energies, far beyond the minimization obtained with self-consistency iterations with a single basis set. Our calculated, indirect band gap is 0.313 eV, at room temperature (using experimental lattice constants of a = 4.4276?\"\" and c = 6.368 \"\"). We discuss the energy bands, total and partial densities of states, and electron and hole effective masses.

International Journal of Population Research , 2013, DOI: 10.1155/2013/304169
Abstract: Introduction. This study used three dependent measures of food security to assess the magnitude of household food insecurity and its consequences on the nutritional status of children 6–36 months in Tamale Metropolis of Northern Ghana. Methods. An analytical cross-sectional study was conducted on a sample of 337 mother/child pairs in June 2012. Food access was measured as household food insecurity access scale (HFIAS), household dietary diversity score (HDDS), and food consumption score (FCS). Results. The magnitude of household food insecurity depended on the food access indicator, with HFIAS yielding the highest household food insecurity of 54%. Of the three food access indicators, 30-day HFIAS was not related to any of the nutrition indices measured. HDDS and FCS were both significantly associated with BMI of mothers and chronic malnutrition (stunted growth) but not acute malnutrition (wasting) with FCS being a stronger predictor of nutritional status. Compared to children in food insecure households, children in food secure households were 46% protected from chronic malnutrition ( , 95% CI: 0.31–0.94). Conclusions and Recommendations. The results of this study show that different measures of household food insecurity produce varied degree of the problem. Efforts at reducing chronic child malnutrition should focus on improving the adequacy of the diet. 1. Introduction Child undernutrition continues to be a major public health problem in developing countries including Ghana. According to the Ghana Demographic and Health Survey, there is substantial regional variation of malnutrition in Ghana, with some of the poorest indicators found in the Northern part of the country. The estimated prevalence of chronic malnutrition, for example, in the Northern Region is 32.4% compared with a national average of 28% [1]. A recent UNICEF Multiple Indicator Cluster Survey (MICS) conducted in 2011 showed that the prevalence of chronic under-nutrition in northern region of Ghana has increased from 32% in 2008 to 37% in 2011 [2]. According to the WHO (2000) classification of malnutrition, the malnutrition situation can be described as serious state in the northern region. The persistent prevalence of chronic malnutrition in Northern Ghana is of particular concern that requires urgent attention and immediate action. To be able to address the problem adequately, it is important that the context-specific risk factors for malnutrition are identified for appropriate interventions to be implemented. The risk factors of malnutrition are multifaceted and complex, and the
The Show-Up Identification Procedure: A Literature Review  [PDF]
Mattias Per Sj?berg
Open Journal of Social Sciences (JSS) , 2016, DOI: 10.4236/jss.2016.41012
Abstract: A show-up is an identification procedure that only presents the witness with one suspect in contrast to a lineup where the suspect is presented among a number of fillers (i.e., known innocent people). This feature makes the show-up procedure very suggestive. In this literature review, an overview of the current research about this identification procedure is presented. The different factors that influence the accuracy in show-up procedures are separated into system (e.g., clothing bias, instruction bias, and the impact of multiple show-ups) and estimator variables (e.g., age, cross-race effects, and alcohol) in line with Wells [1]. The implications of the research are discussed together with suggestions for future research.
