Nosocomial and Community Acquired Infections in Korle Bu Teaching Hospital, Accra
M.J Newman
West African Journal of Medicine , 2009,
Abstract: BACKGROUND: Nosocomial or hospital acquired infection has been recognized as a serious public health problem in the last twenty years. In most hospitals in Africa-South of the Sahara, although the types of community acquired infections are known, neither the magnitude, nor the common types of nosocomial infections has been documented. OBJECTIVE: This study was carried out to find the prevalence of hospital and community acquired infections in hospitals, and to estimate the overall prevalence of HAI and CAI in Korle Bu Teaching Hospital. METHODS: A one-day prevalence survey of nosocomial and community acquired infection in a tertiary-care hospital in Accra was performed using the 1980 British national protocol and the result was analyzed using computerized gargets. RESULTS: Of the 907 patients on admission (on the day of the study), 61 (6.7%) had hospital-acquired infection and 287 (31.6%) had community acquired infection. The commonest hospital acquired infection was wound infection followed by skin and lower respiratory infections. Of the community infections, the most common cases were lower respiratory and skin infections. Fifty-three percent of all patients were on antimicrobial treatment. Patients on metronidazole were 212 (44%), ampicillin/amoxicillin 199 (41.6%), cloxacillin 163 (34%) and gentamicin 135 (28%). Approximately 20% of patients were on three or more drugs. CONCLUSION: This study has shown that the prevalence of community acquired infections in our hospital is much higher than that from nosocomial infections and that the British national survey protocol can be used in countries with limited resources.

El tabaco y su influencia en el periodonto
Avances en Periodoncia e Implantología Oral , 2005, DOI: 10.4321/S1699-65852005000100003
Abstract: periodontitis is a multifactorial disease. smoking is one of the environmental factors that most changes the susceptibility of the individual to the development of the periodontal disease. analogous to what happens at the level of general health, tobacco causes serious adverse effects in the oral cavity, namely in periodontal tissues. the epidemiologic data taken from literature gives important information that is in agreement with the greater part of the criteria of bradford hill for the establishment of a causal relationship between tobacco and periodontitis. the pathogenesis of the periodontal destruction is extremely complex, since there are diverse critical pathways interconnected between them which participate in the outbreak and evolution of the disease. the mechanism of action of tobacco can be explained by its intervention in each of these pathways. in addition to being a risk factor for the disease, tobacco impairs healing and the response to basic and surgical treatment. bibliographical revision of the published works related to the subject will be carried out.

Sobre as origens das defini??es dos produtos escalar e vetorial
Menon, M.J.;
Revista Brasileira de Ensino de Física , 2009, DOI: 10.1590/S1806-11172009000200006
Abstract: the operations of two vector multiplication (the scalar and vector products) are introduced in physics and mathematics textbooks just as a definition, without any reference or discussion on the formal reasons and/or motivations that have led to these structures. in this work, a short pedagogical review on the origins of these definitions is presented. we discuss the formal results obtained by hamilton in the context of quaternionic algebra and some "changes" performed by gibbs and heaviside, leading to what is now usually known as "vector algebra". we present comments on some disadvantages of these "changes", referring to more practical and formal systems (grasmmann and clifford algebras). some basic and recent works on the subject are also mentioned and commented.

Laparoscopic Partial Hepatectomy by Using Horizontal Interrupted Mattress Suture in Goats
M.J. Eesa
Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2010.272.276
Abstract: This study was designed to evaluate the feasibility of laparoscopic partial hepatectomy by using the intracorporeal horizontal interrupted mattress suture technique. Ten Black Iraqi local old goats of both sexes were used. Animals divided into two equal groups. Laparoscopic partial hepatectomy were performed in both groups comparing horizontal interrupted mattress suture by using polygalactine synthesis absorbable suture material, to suture around the resected part as a triangular in shape. Then resected this a triangular area and without approximate of resected edge in group, A. While the same method in group B but with approximation of the resected edge by simple interrupted suture pattern. The animals were inspected laparoscopically, one month post operation, which revealed that the regeneration of the resected site was better in group, B compared with group, A. In addition to that the adhesion of the resected site with adjacent structures were slight in degree in group, B than in group, A. This technique of intracorporeal horizontal interrupted mattress suture provides to be feasible and can be used in laparoscopic partial liver resection of the peripheral abnormal lesion.
Reversion to juvenility: the use of epicormics in the micropropagation of mature wild shrubs of Vaccinium cylindraceum Smith (Ericacaeae)
Arquipélago : Life and Marine Sciences , 2009,
Abstract: An efficient in vitro method was developed to propagate the shoots of mature wild shrubs of Vaccinium cylindraceum Sm. by axillary bud proliferation on epicormic stems. In the initial culture, 46.9% of the epicormic buds produced new shoots with juvenile morphological features. The number of nodes per shoot and the shoot length for explants which originated from epicormic buds was significantly higher when compared to that of winter dormant buds but similar when compared to that of seedling buds. The three most distal buds of epicormic twigs produced the best rates of shoot initiation: 87.5% (position 1) to 62.5% (position 3).
Range extension of Ceratogyrus sanderi Strand, 1906 (Araneae: Theraphosidae)
M.J Fitzpatrick

Abstract: The range of the baboon spider Ceratogyrus sanderi Strand, 1906, previously only known to occur in Namibia, has been extended into the northern and western regions of Zimbabwe.
