Authors: Ibrahim A.K. , Yusuf B.A. , Sambo B.U. 
Published: April 2021

Transition Metal Complexes of Mn(II),Co(II) and Ni(II) with Schiff base derived from 4- chloroaniline and Salicylaldehyde were synthesized and characterized by conductivity measurement, magnetic susceptibility, infrared spectra, metal-ligand ratio determination and solubility test. The Schiff base and its metal complexes were tested for antibacterial activity against Staphylococcus aureus and Escherichia coli and fungal activity against Aspergillus flavus and Mucor species. The low molar conductance values range (16-28.1Ohm- cm2 mol-1) indicated that all the complexes are non electrolytes. The magnetic susceptibility revealed that all the complexes are paramagnetic in nature. The metal-ligand ratio was found to be 1:2 in all the complexes. The infrared spectra suggested that the Schiff base behaves as a bidentate ligand. The antimicrobial studies revealed moderate activity against the tested organism when compared with the standards (Ciprofloxacin and Ketoconazole), and this activity increases by increasing concentration. And also the Metal Complexes showed higher activity than free Ligand due to chelation.Keywords: Salicyldehyde, 4-chloroaniline, Mn(II), Co(II), Zn(II) complexes, antimicrobial activity

Authors: Ado G , Haruna H , Indabawa I.I. 
Published: April 2021

The research was conducted to monitor the performance of some endogenous species of Cyanobacteria for the adsorption of Manganese (Mn), Cobalt (Co) and Nickel (Ni) from untreated effluents of Fata Tanning Limited (FTL) in Kano between July 2014-June, 2015. Primary field investigation and laboratory analysis were the main sources of data in the study. The study areas were divided into three strata within which samples were collected using stratified sampling techniques from a depth of 0 30cm.The study assessed the adsorption capacity of some heavy metals namely; Mn., Co. and Ni using Atomic Absorbance Spectrophotometer (AAS). Indigenous cyanobacteria species identified and isolated were Anabaena variabilis, Lyngbya majusculata and Oscillatoria princeps using microscopy and standard phycological chart as described by Komerak and Anagnostidis, (1989). Bioremediation Bioassay was conducted to evaluate the adsorption capacity of the isolated organisms. The results showed that, tested organisms reduced the concentration level of heavy metals in the effluents to the standard limit proposed by FEPA (1997), WHO (1999) and (ICLARM, 1997). Anabaen was found to remove more Ni (4.13%) followed by Lyngbya (3.78%) all at 9 weeks after inoculation. Higher concentration of Mn (3.85%) and Co of (4.04%) were removed by Lyngbya and Oscillatoria at 9 weeks after inoculation. These findings indicated that all the tested organisms possessed great potential in removin heavy metals from untreated tannery effluents. These findings also showed that adsorption of heavy metals by the tested organisms increased with time from 3-9 weeks of inoculation and adsorption was significantly higher at 9 weeks after inoculation and some decline at 9 WAI.Keywords: Cyanobacterial species, Effluent, FTL and Heavy metals
Synthesis, characterization and antimicrobial activities of schiff base derived from thiourea and anisaldehyde and its Mn(II), Fe (II) and Co(II) complexes
Authors: Siraj I.T. , Sambo B.U. 
Published: April 2021

Complexes of Mn(II), Fe(II) and Co(II) with a Schiff base derived from condensation reaction of thiourea and o-anisaldehyde has been synthesized and characterized analytically and spectroscopically. Melting point of the Schiff base was found to be 160°C and the complexes decomposed within a temperature range of 215 to 275°C. Molarconductances of the complexes were found to be within 1.1 to 3.5W–1 cm2 mol–1 range. Magnetic moment indicated the complexes to be paramagnetic (4.03 to 5.71BM). Infrared spectrum of the Schiff base showed the azomethine peak at 1601cm–1 which shifted up to1687cm–1 in the complexes. The analytical and spectral studies revealed that all the metal(II) complexes are in 1:3 metal ligand ratio, with the Schiff base acting as tetradentate ligand towards the metal ion via azomethine – N, and methoxy –O and two chlorine atoms were further coordinated to the metal(II) ion. The synthesized ligand and its respective metal (II) complexes were screened for their antibacterial activity against Staphylococcus aureus and Escherichia coli strains and antifungal activity against Aspergillus flavus and Mucorindicus. The results revealed that, the Schiff base and the metal (II) complexes showed significant antibacterial and antifungal activities at high concentration.Keywords: Metal complexes, thiourea, anisaldehyde, characterization, antimicrobial
Joseph ki-zerbo et le panafricanisme
Authors: Mare D 
Published: April 2021

Joseph Ki-Zerbo a mené sa vie entière dans le combat panafricaniste. Son parcours panafricain s’est consolidé à travers des rencontres à son initiative personnelle mais aussi grâce à des occasions avec les grands panafricanistes de renom comme le « prophète » Kwame Nkrumah, Amilcar Cabral, Patrice Lumumba, Julius Nyerere etc. Il arriva à joindre l’acte à la parole par exemple en allant prêter main forte à Sékou Touré en 1958, en ayant travaillé à exhumer le passé de l’africain. L’Afrique doit être libérée, et cette libération se fera obligatoirement de façon panafricaine ou elle n’aura jamais lieu. C’est pourquoi, l’Africain doit s’imprégner de son passé pour comprendre les réalités et les obstacles présents qui se posent à lui afin d’envisager les grandes lignes du combat panafricain pour un avenir meilleur. La lecture de l’engagement de Ki-Zerbo se veut une présentation d’un modèle phare pour les jeunes voués et engagés dans le sens du panafricanisme.
Severe gynaecomastia associated with highly active antiretroviral therapy
Authors: Muchemwa Faith C. , Madziyire Clarice T. 
Published: April 2021

The association between gynaecomastia and HIV infection was first reported in 1987; however, there were no subsequent published reports of gynaecomastia linked to HIV infection until highly active antiretroviral therapy (HAART) was introduced. Although HAART significantly improves the prognosis of HIV infection, its extensive use has resulted in multiple adverse effects, including benign breast enlargement. We present a rare case of severe gynaecomastia in a male patient with vertically transmitted HIV on HAART. He was surgically treated with mastectomy with no nipple-areolar complex reconstruction. The pathology report confirmed the benign nature of the breast tissue. Surgical intervention resulted in an improvement of daily activities and enhanced psychosocial wellbeing. Benign bilateral breast enlargement of this magnitude in a male patient has never been reported. Keywords: gynaecomastia; HIV; highly active antiretroviral therapy; efavirenz
Diagnostic accuracy of the Tzanakis score for acute appendicitis in a resource-limited setting: A tertiary hospital-based survey
Authors: Makor Ajak , Jombwe Josephat , Galukande Moses , Elobu Alex E. 
Published: April 2021

Background: The management of acute appendicitis remains challenging with high peri-operative morbidity and mortality due diagnostic delay or high negative appendicetomy rates due to aggressive surgical approaches. CT scan is accurate for pre-operative diagnosis but not available or affordable in all settings. There remains a need for an affordable yet accurate tool for diagnosing acute appendicitis in the resource limited setting. Methods: To determine the diagnostic accuracy of Tzanakis score in the preoperative evaluation of patients with acute appendicitis, we conducted a descriptive cross-sectional study at Mulago Hospital in Kampala, Uganda. Eligible consenting patients diagnosed with acute appendicitis consecutively underwent Tzanakis scoring and appendicectomy. Appencieal samples were sent for histological examination. Sensitivity, specificity, positive predictive value, negative predictive values, and diagnostic accuracy of the Tzanakis scoring system were calculated, relative to histological examination. Results: We enrolled 160 participants of mean age 30.4 years with male:female ratio of 2:1. The Tzanakis score had sensitivity of100% (95% CI 98-100), positive predictive value 97 % (95% CI 95-99), specificity of 64% (95% CI 31-89), negative predictive value of 100%, and overall diagnostic accuracy of 98% with 3% negative appendectomy rate. Conclusions: The Tzanakis score is found to be a sensitive and specific tool that should be considered for preoperative diagnosis of acute appendicitis in resource limited settings.

Septic arthritis is a potentially crippling infection of the joint cavity. Malnutrition in the setting of poor socioeconomic background is a known predisposing and propagating factor of septic arthritis. Prolonged untreated septic arthritis of the hip joint can be a rare cause of acute abdomen, this is due to the proximity of the hip joint to the pelvis causing the spread of the causative organisms into the peritoneal cavity. We present a case of septic arthritis of the hip joint presenting as acute abdomen with intra-peritoneal dislocation of the head of the femur, and reviewed relevant literature.

Authors: ElBadry Salwa , Ghaleb Mervat A. , Abou Zeid Nesreen A. M. 
Published: April 2021

Context: Hemodialysis HD patients, as well as the dialysis staff, are vulnerable to contracting health-care-associated infections (HAIs) due to frequent and prolonged exposure to many possible contaminants in the dialysis environment.
Aim: Assess healthcare personnel HCP opinion and their implementation obstacles regarding standard precautions (SPs) in the hemodialysis unit.
Methods: The study conducted at the hemodialysis unit at Al Mouwasat University Hospital, Alexandria, Egypt. A descriptive research design was used to collect data for this study. All healthcare personnel working in the setting mentioned above were included. Two tools were used. The first tool is a standard precautions practices in hemodialysis observational checklist: The second tool is a structured interview questionnaire to assess the opinion of healthcare personnel regarding the applicability of standard precautions in the hemodialysis unit and their implementation obstacles.
Results: The standard precautions practice score showed unsatisfactory practice among HCP. Regarding their opinion, the majority of HCP disagreed to follow the five moments and reported that the WHO technique of hand hygiene is so sophisticated and time-consuming; they disagreed with changing gloves between patients and considering gloves as a substitute to hand hygiene. The majority recap the needle by two hand techniques disagreed with following respiratory hygiene, and color-coding was accepted only from nurses. Also, it was found that there was a positive correlation between years of experience, infection control training programs, and the level of SPs practice score.
Conclusion: Unsatisfactory SPs practices showed a high percentage of HCP. Healthcare personnel tends to agree to certain infection control practices over other practices. Availability and accessibility of equipment and supplies that interfere with the application of SPs practices and lack of knowledge concerning infection prevention and control were considered as implementation obstacles of SPs practices. Education and training of HCP on SPs, together with consistent and robust management support, are recommended. In addition to the development of national precautions after conducting researches that confirm its effectiveness.

Authors: Khamis Engy A. R. , Abdelaziz Eman , Hemdan Ghada 
Published: April 2021

Context: Urinary problems are common in females, affecting approximately one-third of adult women. Multiple deliveries Reduced pelvic floor strength affects the bladder function because the bladder does not completely empty, leaving a 'pool' of urine, which can lead to recurrent urinary infection. Kegel exercises are the most widely used method for strengthening muscles in the pelvic floor. Patients can do them at any time, anywhere, while doing other work and without regular visits to hospitals.
Aim: The study aims to assess the effects of Kegel Exercises on the recurrence of Lower Urinary Tract Infection in Multiparty.
Methods: A convenience sample of 100 patients suffer from recurrent urinary tract infection (UTI) and (Multiparty) had more than three normal deliveries, assigned randomly and alternatively into two equal groups, 50 in each. The first group (control group) received standard hospital nursing care. The second group (study group) taught Kegel exercises. Outcome measurements included the use of UTI Symptoms Assessment Questionnaire, administered pre and two months post regular Kegel exercises, to assess the severity and bothersome of the most frequently reported symptoms of UTI.
Results: Regarding the degree of symptoms for urinary tract infection in the first visit, the majority of patients in both groups had a maximum degree of symptoms. Regarding all symptoms, the patient suffering from frequency, urgency of urination, pain or burning when passing urine, inability to empty the bladder completely, pain or uncomfortable pressure in lower abdomen/pelvic area, low back pain, and blood in urine with a non-statistically significant difference between both groups. On the other hand, in the second visit, there was a statistically significant difference between patients who received hospital care and study group who practice Kegel exercise regarding all symptoms. There was a statistically significant difference between both groups regarding the severity of urinary tract infections.
Conclusion: Women with recurrent urinary tract infection symptoms exhibit self-reported cure or improvement of urinary tract infection symptoms after the regular performance of Kegel exercises. Applying educational sessions by nurses is recommended for females after normal delivery and caesarian section delivery.

O FUTURO DA ENGENHARIA OU A ENGENHARIA DO FUTURO !
Authors: Fontes Mario Arthur De Souza 
Published: April 2021

Na mitologia Grega há um deus chamado JANUS, que tem um olho só na frente da testa, para ver o futuro e um olho atrás da cabeça, para ver o passado. Se estiver vivo..., mas com certeza deve ainda estar..., porque os deuses não morrem jamais..., assim diz a máxima; e se olhasse a nossa engenharia iria ver com certeza, muitas coisas interessantes, senão vejamos: “vislumbraria com o seu olho de ver o passado e veria uma Engenharia pujante, com grande força tecnológica, construindo a base da infra-estrutura de um País preparado para despontar no”hancking”das grandes Nações do Século XX; JANUS, veria também essa Engenharia, construindo e participando da modernização da superestrutura dessa Nação líder do Continente Sul; veria ainda hoje, a maior hidrelétrica em operação, a usina de geração Itaipú e todo um programa de eletrificação e de domínio do maiores rios que este mundo já postou a olhar; enxergaria o maior programa rodoviário, jamais construído...???, é certo, ficando somente no papel; veria os metrôs de São Paulo e do Rio de Janeiro e tantas e tantas outras obras de envergadura, dessa infra-estrutura; iria ver programas como o Proálcool, o domínio da tecnologia agrícola na vastidão do solo do nosso Centro-Oeste e outros...”. E, o que veria o olho postado na frente da testa de JANUS?“veria em visão máxima de futuro, para este País de dimensões continentais, com certeza,muito pouco de Engenharia e muito de macroeconomia e diga-se de passagem, de péssimaqualidade macroeconômica e etc..., etc..., e etc...”. Na verdade, perdemos o rumo e isso já faz vinte e tantos anos... . Teremos que aprender tudo novamente; aprender a fazer o desenvolvimento econômico, o que não será fácil e nem tão rápido; selecionar empreendedores de caráter ilibado; preparar mão de obra especializada; implementar o entendimento que o maior capital é o trabalho e isso para todos; aumentar a auto-estima dos profissionais brasileiros e sensibilizar o governo federal, para esse grande momento. Mas acreditamos, que uma longa caminhada, começa sempre com um primeiro passo e neste primeiro e importantíssimo passo, somente a Universidade pode ajudar. Porque a Universidade é hoje um lócus onde à luz das idéias, traz a discussão dos aspectos gerais edos multisetoriais da Engenharia e do desenvolvimento, porque aí está o seu vocacional, pois a Universidade é a grande formadora. Ninguém conseguirá preparar esse futuro sozinho, será necessária a ajuda de todos e esperamos que estes sejam muitos...; só assim as coisas poderão acontecer e mudar com certeza. Aí então, o Brasil do futuro se confundirá com a Engenharia do futuro..., e JANUS não ficará obrigado por sua visão de futuro, a ver as coisas se apresentarem ainda hoje, sem nenhuma ou quase nenhuma perspectiva em curto prazo. Todos deveremos acreditar, ter certeza e muita fé neste futuro o que para isso, somente teremos que encará-lo.
