Effect of processing conditions on oil point pressure of moringa oleifera seed.

Seed oil expression is an important economic venture in rural Nigeria. The traditional techniques of carrying out the operation is not only energy sapping and time consuming but also wasteful. In order to reduce the tedium involved in the expression of oil from moringa oleifera seed and develop efficient equipment for carrying out the operation, the oil point pressure of the seed was determined under different processing conditions using a laboratory press. The processing conditions employed were moisture content (4.78, 6.00, 8.00 and 10.00 % wet basis), heating temperature (50, 70, 85 and 100 °C) and heating time (15, 20, 25 and 30 min). Results showed that the oil point pressure increased with increase in seed moisture content, but decreased with increase in heating temperature and heating time within the above ranges. Highest oil point pressure value of 1.1239 MPa was obtained at the processing conditions of 10.00 % moisture content, 50 °C heating temperature and 15 min heating time. The lowest oil point pressure obtained was 0.3164 MPa and it occurred at the moisture content of 4.78 %, heating temperature of 100 °C and heating time of 30 min. Analysis of Variance (ANOVA) showed that all the processing variables and their interactions had significant effect on the oil point pressure of moringa oleifera seed at 1 % level of significance. This was further demonstrated using Response Surface Methodology (RSM). Tukey's test and Duncan's Multiple Range Analysis successfully separated the means and a multiple regression equation was used to express the relationship existing between the oil point pressure of moringa oleifera seed and its moisture content, processing temperature, heating time and their interactions. The model yielded coefficients that enabled the oil point pressure of the seed to be predicted with very high coefficient of determination.

Knowledge of Ocular Complications of HIV/AIDS among Hospital Workers in a Tertiary Institution

Since the commencement of the Highly Active Antiretroviral Therapy; there has been increase longevity among people living with HIV/AIDS ; a factor which was thought initially to be related to the low prevalence of its ocular complication in Sub-Saharan Africa. In fact some of its ocular signs have been identified as stigmata of HIV. It is therefore important that all health workers and not only eye care workers know about these eye complications. However there seems to be no study on the knowledge of health workers about ocular complications of HIV/AIDS. This study aimed at determining the knowledge of hospital workers in a tertiary institution in Western Nigeria about Ocular Complications of HIV/AIDS. The hospital workers excluding the eye care workers; administrative staff and security staff of Olabisi Onabanjo Teaching Hospital completed a structured self administered questionnaire. The interview covered demographics; cadre in health work; awareness of HIV/AIDS and its transmission; knowledge of its Ocular complications. Their responses were analysed using SPSS statistical package; version 11.0. 72.2knew that HIV/AIDS could affect the eye which is related to the status of health work (P= 0.00) .About 50of hospital workers do not know the part of the eye that HIV/AIDS could affect and another 52.5says it affect the eye only at the late stage. Knowledge about different eye complications was generally low. Only 28.6knew that it could present first as an eye problem. The knowledge of hospital workers about eye involvement in HIV/AIDS is low there is need to create awareness through regular workshops and seminars; which will in turn help to reduce ocular morbidity and mortality among the people living with HIV/AIDS

Assessment of violence against women in Kano metropolis, Nigeria.

BACKGROUND: Violence against women, in its various forms, is endemic in communities and countries around the world, cutting across class, education, race, age, religious and national boundaries. AIMS AND OBJECTIVES: This descriptive cross-sectional study was conducted to identify various forms of gender based violence affecting women in Kano metropolis, determine factors responsible for gender based violence and use this to suggest ways of preventing gender based violence. SUBJECTS AND METHODS: Respondents for this study were selected from the eight metropolitan Local Government Areas of Kano State, Nigeria. Six hundred adult males and females were selected through a multi-stage sampling technique by the use of questionnaire as the data tool. RESULTS: More than three quarters 436 (75.7%) of the respondents knew that women are subjected to various forms of verbal abuse in their homes by their spouses. Deprivation of assess to health care and education was identified by 454 (78.8%) and 490 (85.15) respondents as challenges faced by women at homes. Majority of the respondents 498 (86.4%) identified financial reason, four hundred and forty (76.4%) respondents mentioned unfaithfulness and three-quarters 434 (75.3%) of the respondents said refusal of sexual advance is a reason for violence activities witnessed by women in their respective homes. There was a statistically significant relationship in opinion of male and female on coercion of wife for sexual activities when she is tired and when she is not in the mood (p-value=0.0000). CONCLUSION: Government and Non Governmental organisation should intensify activities to promote awareness and advocacy on violence against women. Involvement of males in all programmes relating to violence against women should be done especially since the perpetrators in most cases are men.

Community awareness of bird flu and the practice of backyard poultry in a North-Central state of Nigeria.

INTRODUCTION: The practice of backyard poultry is a very common practice in many homes in Nigeria. Birds raised at home are usually free ranged, which increases close contact between man and birds, thus increasing the risk of transmission of avian influenza virus to man. This study investigated the awareness of bird flu infection and identifies risk factors associated with the practice of backyard/free ranged poultry among the residents of a state in Northern Nigeria. METHODS: This cross-sectional study was carried out in Kwara State using 130 wards selected through cluster sampling technique. Households in each ward were sampled through systematic random sampling technique using the primary health care house numbering register. Semi-structured questionnaire was used to generate relevant information through interview and 650 participants consented and were used for the study. RESULTS: Most of the respondents 604 (92.9%) kept birds in their homes and one-third 204 (33.8%) of this group knew that infection from birds can be transmitted to man. However, less than a third 186 (30.8%) of those who keep birds were aware of avian influenza (AI) infection. Out of the 186 respondents, 78 (41.9%) had experienced massive bird deaths in the preceding year prior to the interview. Less than half 81 (43.5%) were willing to report AI or massive deaths occurring in flocks of their birds to designated officers /authority. During outbreaks with massive deaths in birds some of the respondents sold infected live birds 45 (57. 7%), few slaughtered and dressed the birds before sale 11 (14.1%), while some slaughtered and consumed the birds in their families 19 (24.4%). CONCLUSION: The practice of backyard poultry is very high with little knowledge and awareness of mechanism and risk of infection associated with it. This was also reflected in their attitude towards reporting of outbreaks in birds. Public awareness campaign and home visit by environmental and veterinary officers are important strategies that can prevent AI infection transmission among domestic birds and man.

Postpartum sexual abstinence and breastfeeding pattern in Sagamu, Nigeria.

This was a prospective study involving 371 mothers. The mean age of the mothers was 27.5 (.3.6) years with a mean years at school (Educational years) of 11.3 (2.9) years. All the mothers had previously breastfed at one of their infants for at least 6 months, while the mothers also breastfed their last child for an average (mean) of 10.3 (4.0) months. The overall mean of previous live births was 1.9 (0.8). In the first month postpartum, 84.6% of the mothers abstained from sexual intercourse, but by the 4th-5th month the proportion had dropped to 18.1%, with just 2.1% of the study population abstaining from sexual intercourse at 11-15 months post-partum. Forty seven (13.5%), 30 (8.6%) and 3 (0.9%) mothers in social classes 2,3 and 1 respectively have resumed sexual intercourse at 4-5 months, while only 12 (3.4%) and 4 (1.1%) in social classes 2 and 3 respectively continued with sexual intercourse at 11-15 months. More mothers resumed sexual intercourse from 1 to 15 months post-partum when they breast fed for 6-10 minutes and 11-15 minutes than those who breast fed for 1-5 minutes, 16-20 minutes and 21-25 minutes. Also more mothers within the 25-29 years age group resumed sexual intercourse from the first month to the fifteenth month post-partum than mothers in the other age groups.

HIV sero-prevalence among newly diagnosed adult pulmonary tuberculosis patients in Sagamu.

BACKGROUND: [corrected] The association between Tuberculosis (TB) and Human immunodeficiency virus (HIV) has been described in several studies. TB was well represented in the first description of AIDS in Africa. In 1999, 25% of TB cases were attributable to the spread of HIV/AIDS. Frequencies of between 54-79% were recorded in medical in-patients in our hospital. The objective of the study is to assess the frequency of HIV in TB outpatients attending the tuberculosis and leprosy control centre in Sagamu. METHODS: A cross-sectional study of adult tuberculosis patients admitted into the DOTS programme of the TB and leprosy control centre, Olabisi Onabanjo University Teaching Hospital, Sagamu between January 2001 and December 2002 was undertaken. Free anti tuberculosis drugs were provided by the German leprosy Relief Association. Data was collected using interviewer-administered questionnaire. HIV screening, packed cell volume and sputum microscopy for acid fast bacilli were carried out on all patients. RESULTS: A total of 269 cases of pulmonary T.B were registered at the clinic of which 40 (14.9%) were HIV sero-positive. The peak age prevalence was in the 3d decade accounting for 42.5% of cases, followed by 32.5% in the 2rd decade. There was a statistically significant difference in the bacillary count and packed cell volume between HIV positive and negative TB patients. The mean weight at presentation, sputum positivity rate and sputum conversion rate at the end of two months of therapy was similar in both HIV positive and negative TB patients. CONCLUSION: This study has demonstrated a frequency of 14.9% of HIV sero-prevalence amongst our TB population. Efforts should be intensified to ensure adherence to INH prophylaxis among HIV infected individuals in TB endemic areas as well as strengthening preventive measures.

Infant feeding and lactational amenorrhea in Sagamu, Nigeria.

Five hundred and twenty educated, breastfeeding women in Sagamu, Nigeria, were observed prospectively in order to describe their infant feeding practices and to determine whether any predictors of the return of menses could be identified. The women remained amenorrheic for seven months. Compared with similarly selected women in other countries, they regularly fed their infants with supplements from a very early age, yet breastfeeding frequency and duration did not decline dramatically. Semi-solid food was introduced at about four months and such supplementation, as well as earlier supplementation with milk/milk-based feedings, was associated with the return of menses. The median duration of abstinence was about four months but the mean may have been much longer. No woman became pregnant until her infant was weaned.

For better data, better utilized.

In Nigeria a training programme was devised whereby staff from health centres could appreciate the value of reliable data as a means of raising the standard of services. A process of learning by doing enabled the participants to turn routine data into tools for management and the improvement of service quality.

Studies on the effectiveness, safety and acceptability of fluids from local foodstuffs in the prevention and management of dehydration caused by diarrhoea in children.

Two fluids derived from local staple food, Manioc Salt Solution (MSS) and Pap Salt Solution (PSS) were assessed and compared with the World Health Organization/Oral Rehydration Solution (WHO/ORS) in 333 children aged between 6 and 60 months in a clinical trial. All the children had some dehydration after episodes of acute watery diarrhoea using WHO criteria. All the children who were placed on MSS and PSS, as well as ORS were satisfactorily rehydrated. There was no significant difference in pre- and postserum electrolytes of the children on the three types of fluids. The fluids were found to be acceptable, readily available, easy to prepare and cheaper than the ORS fluid. There was no taboo against the fluid. It is noteworthy that there was no significant difference in the sugar and electrolyte contents of the different varieties of the manioc and pap available in this environment, thus making the MSS and PSS effective and readily available substitutes to ORS. The two fluids are therefore recommended as rehydrating fluids for children with some dehydration in the absence of WHO/ORS fluid.

Clinical trial of pap-salt solution in the treatment of dehydrated children.

PIP: In a randomized clinical trial the efficacy of Pap-salt solution (PSS) was compared with the World Health Organization (WHO) oral rehydration salt (ORS) solution in 212 children 6 months to 5 years old: 101 cases (52 males and 49 females) and 111 controls (41 males and 70 females) at the primary health care centers of Ijebu-Igbo, Ita-Oba in Sagamu, and at the oral rehydration therapy (ORT) unit of the Ogun State University Teaching Hospital, Sagamu, Nigeria, between June 1991 and June 1992. 164 children (77.3%) belonged to the lowest socioeconomic classes. Maize pap (Ogi) was prepared by soaking maize in water for 2-3 days for fermentation to occur. PSS was prepared from raw pap and the cooked pap was then made up to 600 ml with the addition of more water and 3 ml of table salt. Each child received 75 ml per kg of ORS solution or PSS orally over a 4-hour period. Those patients who still showed signs of dehydration were given a further 75 ml/kg of the same solution over another 4-hour period. The patients were followed up on 2 consecutive days at home by community health nurses. All the 101 children who received PSS were successfully treated and the remaining 2 were lost to follow-up. There was no significant difference in the mean volumes of PSS (1015.4 ml) and ORS (1036 ml) required for rehydration (p 0.05). 96 mothers found PSS easy to prepare and readily accepted by their children, and 97 stated that the ingredients required for preparation were available. There was no difference ( p 0.05) in the pre- and post-treatment values of the serum electrolytes in the 2 groups. PSS was acceptable to the patients, readily available, and much cheaper than the ORS solution. Therefore, PSS is recommended for the rehydration of children with mild dehydration in situations where ORS solution is not available.^ieng

Clinical trial of pap-salt solution in the treatment of dehydrated children

In a randomised clinical trial; the efficacy of pap-salt solution (PSS) was compared with the WHO oral rehydration salt (ORS) solution in 212 children; aged between six months and five years. All the children who received PSS were successfully treated and there was no difference (p0.05) in the pre- and post-treatment values of the serum electrolytes in the two groups of children. Pap-salt solution was acceptable to the patients; readily available and much cheaper than the ORS solution. PSS is; therefore; recommended for the rehydration of children with mild and some degree of dehydration in situations where ORS solution is not available
