ED Jatau, OS Olonitola

 

Abstract

A total of 125 Neisseria gonorrhoeae strains were isolated from patients attending private clinics in Zaria, Kaduna State, Nigeria. Out of the 125 gonococcal isolates, 90 (72%) were resistant to penicillin G, 85 (68%) to ampicillin, 70 (56%) to tetracycline, 55 (44%) to erythromycin and 26 (22%) isolates were resistant to gentamicin. All the 125 Neisseria gonorrhoeae isolates were susceptible to ceftriaxone, cefuroxime and ofloxacin. Out of the 90 Neisseria gonorrhoeae isolates resistant to penicillin, 65 (72.2%) were positive for β-lactamase production (PPNG). The remaining 25 (27.7%) penicillin resistant strains were β-lactamase negative. The findings of this study have shown high prevalence of multi-drug resistant strains of Neisseria gonorrhoeae amongst attendees of private clinics in Zaria.

Knowledge, attitude and practice of the trainee seafarers to HIV/AIDS and STIs at Apapa Seaport, Lagos

AM Efunsile, OO Oduyebo, WA Oyibo, FT Ogunsola, FA Fatungase, OA Osinupebi

 

Abstract

The epidemic of human immunodeficiency virus (HIV) in Nigeria is being fuelled by ignorance and other Sexually Transmitted Infections (STIs). Little is known about HIV-risk related sexual behavior of the Nigerian sailors. This study describes the baseline knowledge, attitude and practice of the trainee sailors to HIV.
Ninety four (83.2%) of the 113 trainee interviewed consented to participate in voluntary counseling and confidential testing (VCT) programme. Each trainee completed an anonymous self- administered questionnaire and was tested for syphilis, trichomoniasis and HIV.
Seventy one (75.5%) of the respondents were between ages 21-25 years. Twenty three (25%) did not believe that having sex with commercial sex workers puts them at high risk of HIV while eighteen (19.1%) did not believe that condoms were protective. Only ten (10.6%) practiced abstinence while three were homosexual. Despite all these, sixty three (67%) believed that they were at little or no risk of HIV, prevalence of which was found to be 5.3% among them. Seventy one (75.5%), fifteen (16%), twenty (21%) and (20.2% of respondents believed that genital ulcers, gonorrhea, syphilis and HIV respectively were not sexually transmitted. Trichomoniasis and syphilis were found in two (2.1%) and one (1.1%) respondents respectively. Female sex (P=0.002) and trichomoniasis (P=0.017) were found to significantly influence HIV infection.

There was a high level of ignorance about HIV and STIs among respondents. This was further highlighted by the high rate of high-risk behaviors. Therefore, sustained educational programs and promotion of condoms are recommended to address this problem.

Effects of health education intervention on knowledge, attitude and practice of youths concerning HIV/AIDS in rural Nigerian community

IC Ajewole, GK Osagbemi

 

Abstract

Acquired Immune Deficiency Syndrome (AIDS) caused by Human Immunodeficiency virus (HIV) has been a major public Health issue affecting millions of individuals around the World. No continent is spared.
HIV/AIDS is the most deadly of all the sexually transmitted infections. HIV/AIDS epidemic could has incalculable implications for Agriculture, Business and Socio-Economic development of a country.
This intervention study was carried out between June and October 2006 with the aim of assessing the impact of health education on the Knowledge Attitude and Practice of youths concerning HIV/AIDS. Preliminary KAP was assessed among study and control groups with the aid of a structured questionnaire designed by the researchers. This was followed by the intervention stage with health education given to the youths in the study group and subsequent evaluation of the impact using the same instrument used at the preliminary stage. The study took place in Ikerre Ekiti, a rural community in Ekiti state, Nigeria.
The results showed increase in the level of knowledge among the intervention group on STI & HIV/AIDS from 70.7% to 100%. The attitude and practice of the study group were also statistically different from the control group after intervention.
It was concluded that infection rate can be reduced by public health initiatives such as health education. To reduce the rate of spread of HIV infection, it is recommended that HIV/AIDS education be vigorously pursued amongst adolescents.

Evaluation of measles vaccine cold chain in Lagos State, Nigeria

A O Oyefolu, A C Nwaeke, R A Audu, K O Akinyemi, O B Salu, C P Muller, S A Omilabu

 

Abstract

The National (level 1), State (L2), and Local government vaccine cold stores (L3) as well as some vaccination centres (L4) were physically inspected in Lagos State, Nigeria and the potency of the live-attenuated measles vaccine was tested. Both the L1 and L2 storage facilities were formally adequately equipped and maintained. This was also reflected in the potency of the vaccines. However, many vaccines at L1 were within weeks from expiration. Considerable problems with refrigeration and delayed forwarding became apparent at level L3 causing loss in potency both at L3 and L4: although, all L4 stores check-listed met all the EPI/NPI accreditation criteria, ¾ of the vaccines were sub-potent and this situation did not improve over the three year study period (1996-98). Time to expiration did not seem to be the main cause of loss of potency but rather poor and delayed handling. It is recommended that vaccines are moved more rapidly through the system and used well before expiration. Because of frequent power failures despite standby generators, we further recommend to include in the WHO criteria, book-keeping of periods of power failures, running time of generators and a complete recording of fuel consumption. Attitudes among vaccinating staff and handling of vaccines should also be improved by continued training.

Biochemical basis of heavy metal induced stress tolerance in the N2 fixing cyanobacterium Anabaena doliolum

P Sultan, S M Shah, P Williams, A Jan, N Ahmad

 

Abstract

The effect of heavy metals (Cd and Cu) on the nitrogen fixing cyanbacterium, Anabaena doliolum was observed in the present study. To explore the survival strategy of the test cyanobacterium, Chl/CAR content, protein content, antioxidative defense system ( SOD, APX and GR) as well as biochemical fractionation (carbohydrates, lipids, protein, DNA and RNA) were studied. Increasing concentrations of metals inhibited the growth and survival significantly; chlorophyll and carotenoid content were found inhibited with increase in concentration of metals. Among the antioxidative enzymes, SOD and APX were increased with the increase in concentration of both the metals, whereas Catalase and Glutathione reductase were decreased at higher dose of Cd and Cu. APX played a major role for scavenging H2O2 rather than CAT. Results revealed decrease in all parameters with the duration of time. The role of metal induced PC in offering tolerance to UV-B was confirmed by measuring lipid peroxidation and antioxidant defense system of the cyanobacterium treated with Cd and UV-B as well as in the Cd pretreated cells of A.dolium exposed to UV-B. Lipid peroxidation (measured in terms of MDA content) as well as SOD and APX were found to be less induced, thus showing less oxidative damage incase of interactive treatment when applied separately. However, CAT and GR which showed sensitivity at higher dose of both the stresses were found to be induced. Thus Cd appears to antagonize the effect of UV-B in test cyanobacterium. To know the actual reason for the antagonism, PC concentration was measured in the cells with and without BSO (a potent inhibitor of phytochelatin synthase) pretreatment. The results emphasized that the extent of antagonism was reverted in the BSO pretreated cells than the normal BSO non- treated cells. Nevertheless, the PC content was found to be more in case of Cd + UV-B than the individually treated cells, but the PC was more or less completely inhibited after BSO pretreatment in all the cases. The above finding was also visualized on the SDS-PAGE. Therefore this study showed that Cd induced PC has role in UV-B tolerance.

The role of genital chlamydial infection in acute pelvic inflammatory disease

O K Obunge, C T John

 

Abstract

The polymicrobial nature of pelvic inflammatory disease (PID) underscores the need for a clearer understanding of the pathogenesis and etiology of PID especially among core groups most at risk. This study was designed to determine the role of specific microbial infections in leading to PID among women. Prevalence of genital chlamydial infection and other reproductive tract infections were determined in 100 women presenting at a health facility at Port Harcourt, Rivers State, Nigeria. The result showed that 11.1 per cent of women with acute PID were infected with Chlamydia trachomatis as compared to 4.3 per cent in the control group (odds ratio 2.75: 95% confidence interval (CI), 0.7-11.7). Neiserria gonorrhoeae was not detected in either of the two groups. Trichomoniasis (10% in PID cases and no case in control group) and bacterial vaginosis (17.5% and 4.3% in PID and control group respectively: Odds ratio 4.7, 95% CI, 1.0-21.1) were also significantly associated with the clinical picture suggestive of acute PID. It is recommended that where resources are limited, patients presenting with acute PID be treated empirically for Chlamydia trachomatis, trichomoniasis, bacterial vaginosis and gonorrhoea.

An out-break and observations on Trypanosomiasis in Fresian cattle at Sabon-birni, Kaduna State of Nigeria

A O Fajinmi, J N Abenga, F A Lawani, J C Ukah, E C Ikemereh, P U Nwabuko

 

Abstract

Bovine trypanosomiasis has clinical features characterized by anorexia, emaciation, anemia and the prognosis is usually guided culminating in death. An out-break of trypanopsomiasis was reported and subsequently investigated in Batagarawa farms, Sabon-birni, Rigachukwu LGA Kaduna State of Nigeria. Clinical observations were made on parameters including appearance, temperature, pulse rate, respiratory rate, color of conjunctiva and lachrymal secretions. Record of pre and post treatment indices were also taken.

Trypanosoma congolense was isolated from five (5) Friesian cattle out of forty (40) Friesian cattle sampled representing 12.5%. Several workers had reported the occurrence of trypanosomiasis in cattle and goats. The present study deals with the observations on naturally occurring trypanosomiasis in Friesian cattle.

Haematological examinations were performed employing routing procedures. Biochemical activities and parameters were determined by standard calorimetric method using blood chemistry analyzer. Animals were treated with start doses of Berenil (3.5mg/kg body weight) intramuscularly.

Trypanosomiasis has been recognized as a disease of great economic importance as it generally causes heavy production losses by reduction in milk and other protein yields. There is emaciation in sub-acute and chronic conditions, low working capacity and high mortality in acute cases. This study confirmed that trypanosomiasis is a threat to introduction of exotic breeds of cattle into Nigeria.

Endometrial Tuberculosis i ninfertility: Report of 2 cases and a review of the literature

B A Ojo, L I Akanbi, S O Samuel, M S Odimayo, O A Adesiyun

 

Abstract

Tuberculosis is a chronic granulomatous disease affecting human and many other mammals. Most human diseases are caused by M.tuberculosis but some are due to M.bovis.(1).
Tuberculosis of the tubes and endometrium is intimately bound to the problem of sterility. Despite the decline in frequency of genital tuberculosis in industrialized world coupled with widespread use of antibiotics worldwide, it still remain a possible cause of female infertility especially in developing world.(2)
It was the commonest diagnosis among infertile population in India (3), Malaysia (4) and Saudi Arabia (5). Nigeria, U.S.A., and Pakistan have reported a low and infrequent findings (6,7,8).
Endometrial tuberculosis seems to occur when the ovaries and uterus are in a state of activity (9) and it derives its significance as a clinical entity because of its tendency in focusing on those in these reproductive age group.
Tuberculosis of the genital tract gives rise to few symptoms especially in its mild or moderate phase, its discovery is usually made unexpectedly but will render a large percentage of infected women sterile unless detected and treated adequately in its earliest phases. The cases presented below is to highlight its clinical presentation and to serve as a reminder that pelvic tuberculosis still exist and will not disappear unless tuberculosis is completely eradicated.

Beliefs and perceptions about Acquired Immunodeficieny Syndrome (AIDS) of a Nigerian rural community: Implication for prevention and policy initiative

G T Jombo, D Z Egah, J T Akosu, E W Mbaawuaga

 

Abstract

Acquired Immunodeficiency syndrome (AIDS) has assumed a disease of epidemic dimension both in Nigeria’s rural and urban communities. Different people have varying knowledge and beliefs about this disease. This study was designed to assess the beliefs and perceptions of the people of Ihugh community in that regard.
A structured questionnaire was interviewer administered to assess their beliefs and perceptions about AIDS, results were analyzed by simple descriptive methods.
Of the 500 respondents, 65%(n=325) believed that AIDS is found only in cities while 69.7%(n=345) were of the opinion that AIDS can be cured by traditional means. Sixty five percent (n=326) believed that some people are destined for AIDS while 75.8%(n=482) were of the opinion that AIDS can be acquired through witches and wizards; 71.1%(n=488) believed AIDS can be acquired through curses. A large number of the respondents (63.0%) claimed they did not know where to go for routine HIV screening.
Conclusion: Health education program should be designed for the people of Ihugh community in the context of their peculiarities. This should include town cry, health talk at their worship centres and local gatherings. The electronic and print media are not the best based on their peculiarities.

Keywords: Beliefs; Perceptions; Acquired Immunodeficiency Syndrome.

Human intestinal parasitism in a rural settlement of northern Nigeria, a survey

G T Jombo, D Z Egah, J T Akosu, E W Mbaawuaga

 

Abstract

Intestinal parasites are still a common feature among our communities. This study was set out to ascertain this. One hundred and fifty respondents were recruited into the study. A pretested questionnaire was administered to the respondents with specific hygienic components such as: sources of drinking water, methods of sewage disposal and water purification among others. Stool samples were collected and analysed microscopically and findings analysed.
The overall prevalence of intestinal parssites in Mbangough community was 62%(96 out of 150). The commonest parasite encountered was Ascaris lumbricoides (44%), followed
by Enterobius vermicularis (14%) and Entamoeba histolytica (11.3%). Other parasites were Entamoeba coli 3.3%, Hookworm 6.0%, Schistosoma mansoni 1.3%, Taenia species 7.3%, while the least common parasite encountered was Strongyloides stercoralis 0.6%.. None of the respondents had access to pipe borne water or bore hole.
The prevalence of intestinal parasites in Mbangough community is still quite high. Government should invigorate in her pursuit towards the provision of primary health care facilities in our communities Also health education should be made a compulsory course in all primary schools as well as all adult and literacy classes
