First report of polymelia and a rudimentary wing in a Nigerian Nera black chicken
A case of polymelia with a rudimentary wing is described in an eight-week-old Nera black chicken (Gallus domesticus). It is a rare disorder with chromosomal aberrations, which are associated with congenital limb malformations. The condition was observed during routine physical examination of a flock of 2000 poultry birds in the month of February 2008 in Ibadan, Nigeria. After physical examination, the bird was found to have two extra well-developed legs, which were shorter than the normal legs. These extra legs were also found to be non-functional. Similarly, a rudimentary wing, which was highly vestigial, was found on the left lateral side of the bird very close to the cloaca. The bird died at the age of eight weeks. This is the first reported case of polymelia with a rudimentary wing in a domestic chicken in Nigeria
The effects of prolonged oral administration of the disinfectant calcium hypochlorite in Nigerian commercial cockerels
This study was designed to investigate the effects of prolonged oral administration of calcium hypochlorite in the drinking water of commercial cockerels. It was carried out in order to ascertain probable toxicity associated with prolonged exposure to calcium hypochlorite. Thirty-two healthy birds were used; they were grouped into four groups of eight. Group 1, which served as the control, received 10 mL/kg body weight of physiological saline. Groups 2, 3 and 4 received 0.0375 g, 0.375 g and 0.75 g of calcium hypochlorite per 10 litres of drinking water for six weeks respectively. Six weeks after the administration of calcium hypochlorite, blood was collected from the jugular vein to assess liver function, lipid profiles and for markers of oxidative stress. The results revealed a significant (p < 0.05) increase in alanine aminotransferase activity in a dose-dependent manner when compared with the control. Also, there was a significant (p < 0.05) increase in aspartate aminotransferase and alkaline phosphatase activity. Similarly, there was a significant (p < 0.05) increase in total cholesterol, triglycerides, high-density lipoprotein and low-density lipoprotein levels compared with the control. There was a significant increase in malondialdehyde and hydrogen peroxide generation with a concomitant significant (p < 0.05) decrease in serum glutathione level in a dose-dependent manner when compared with the control. In this study, calcium hypochloriteinduced hepatic damage via oxidative stress and decrease in antioxidant defense system was found. Therefore, prolonged exposure of chickens to calcium hypochlorite is potentially harmful
Comparative evaluation of processes for production of soybean meal for poultry feed in Nigeria Evaluación comparativa de procesos para la producción de harina de soya para la alimentación de pollos en Nigeria
This work examined and compared three processes for production
of low trypsin inhibitor soybean meal. Soybean flour was
subjected to roasting, autoclaving and steaming to denature trypsin
inhibitors. Roasting was done at 120, 130, 135 and 140 ºC for
5, 7, 8 and 9 minutes, respectively. Autoclaving was carried out
at 121ºC, 15psig for 20, 30, 40 and 50 minutes. Steaming was
carried out at 105 ºC for 10, 12, 15 and 18 minutes. Defatting of
the samples was done and the activity of trypsin inhibitor was
investigated. Proximate analysis and quality tests was carried out
to ascertain quality of the heat treated soybean meals. Trypsin
inhibitor in the soybean meals from the three heat treatment
processes ranged from 1.20 to 3.54mg/g while that of raw sample
was 6.01mg/g. Percentage crude protein in all the heat treated
samples ranged from 39.38 to 40.58 % while that of raw sample
was 44.60 %. Urease index ranged from 0.11 to 2.07 % for all
heat treated samples while it was 2.11 % for the raw samples.
% KOH protein solubility in Soybean meal from the three
processes ranged from 45.2 to 73.1 % while that of the raw sample
was 49.1%. The results were statistically significant at p>0.05. At
significance level of p>0.05 it was established that local soybeans
can be processed with adequate heat to obtain low activity soybean
meal with good nutrient standard. The steaming process operated
at 105 ºC for 18 minutes gave the best overall results with trypsin
inhibitor activity of 1.20 mg/g
Evaluation of Customer service and Retention; A Comparative Analysis of Telecommunication Service Providers
For a product to receive complete loyalty depends not only
on the quality of the product but also on the satisfaction
derived from such product. All three, loyalty, quality and
satisfaction are significant factors that show how effective the
customer service of an organization is. When customer service is
effective then customer retention/ retention of product is
considered. This study was carried out to investigate on the
effectiveness of customer service in the retention of GSM SIM
packs using a comparative analysis. Data were collected through
the use of questionnaire administered to a determined sample
size of users of the three major GSM service providers. Data were
analyzed and the four hypotheses were tested using correlation
and ANOVA. This study shows that with effective customer
service, customer loyalty and customer satisfaction and
customer retention can be achieved. Though it is observed that
to achieve the afore-mentioned factors, concepts such as
customer expectation, customer-focus and service quality should
be regarded with utmost importance

Epidemiology of complications of male circumcision in Ibadan, Nigeria
BACKGROUND: The number of infants managed for neonatal circumcision injuries in our unit has been on the increase over the past 16 years. In our search for the sources and reasons for these injuries, we were unable to identify any previous studies of circumcision injuries from our environment. We therefore decided to carry out this study in order to shed some light on this growing problem. METHODS: The patients were made up of 370 consecutive consented children attending our infant welfare clinic for immunization over a period of 3 months. Information on their demographic data, their age at circumcision, where, why and who circumcised them was obtained from their mothers. They were clinically examined for the presence and type of complications of circumcision. RESULTS: Our circumcision rate was 87%. Neonatal circumcision had been performed in 270 (83.9%) of the children. Two hundred and fifty nine (80.7%) were performed in hospitals. The operation was done by nurses in 180 (55.9%), doctors in 113 (35.1%) and by the traditional circumcisionist in 29 (9%) of the children. Complications of circumcision occurred in 65 [20.2%] of the children. Of those who sustained these complications, 35 (53.8%) had redundant foreskin, 16 (24.6%) sustained excessive loss of foreskin, 11 (16.9%) had skin bridges, 2 (3.1%) sustained amputation of the glans penis and 1 (1.5%) had a buried penis. One of the two children who had amputation of the glans also had severe hemorrhage and was transfused. Even though the complications tended to be more likely with nurses than with doctors or traditional circumcisionists, this did not reach statistical significance (p = 0.051). CONCLUSION: We have a very high rate of complications of circumcision of 20.2%. We suggest that training workshops should be organized to adequately retrain all practitioners of circumcision on the safe methods available
Children with Moderate Acute Malnutrition with No Access to Supplementary Feeding Programmes Experience High Rates of Deterioration and No Improvement: Results from a Prospective Cohort Study in Rural Ethiopia
Background: Children with moderate acute malnutrition (MAM) have an increased risk of mortality, infections and impaired physical and cognitive development compared to well-nourished children. In parts of Ethiopia not considered chronically food insecure there are no supplementary feeding programmes (SFPs) for treating MAM. The short-term outcomes of children who have MAM in such areas are not currently described, and there remains an urgent need for evidence-based policy recommendations.
Methods: We defined MAM as mid-upper arm circumference (MUAC) of ≥11.0cm and <12.5cm with no bilateral pitting oedema to include Ethiopian government and World Health Organisation cut-offs. We prospectively surveyed 884 children aged 6–59 months living with MAM in a rural area of Ethiopia not eligible for a supplementary feeding programme. Weekly home visits were made for seven months (28 weeks), covering the end of peak malnutrition through to the post-harvest period (the most food secure window), collecting anthropometric, socio-demographic and food security data.
Results: By the end of the study follow up, 32.5% (287/884) remained with MAM, 9.3% (82/884) experienced at least one episode of SAM (MUAC <11cm and/or bilateral pitting oedema), and 0.9% (8/884) died. Only 54.2% of the children recovered with no episode of SAM by the end of the study. Of those who developed SAM half still had MAM at the end of the follow up period. The median (interquartile range) time to recovery was 9 (4–15) weeks. Children with the lowest MUAC at enrolment had a significantly higher risk of remaining with MAM and a lower chance of recovering.
Conclusions: Children with MAM during the post-harvest season in an area not eligible for SFP experience an extremely high incidence of SAM and a low recovery rate. Not having a targeted nutrition-specific intervention to address MAM in this context places children with MAM at excessive risk of adverse outcomes. Further preventive and curative approaches should urgently be considered
Primary osteogenic sarcoma of the breast
BACKGROUND: Primary extra-osseous osteogenic sarcomas have been reported in many tissues of the body but their occurrence in the breast is extremely rare. It can arise as a result of osseous metaplasia in a pre-existing benign or malignant neoplasm of the breast or as non-phylloides sarcoma from the soft tissue of a previously normal breast. CASE PRESENTATION: A 40 year-old Nigerian woman was clinically diagnosed to have carcinoma of the left breast. The histology report of core-needle biopsy of the mass showed a malignant neoplasm comprising islands of chondroblastic and osteoblastic stromal cells. This report changed the diagnosis from carcinoma to osteogenic sarcoma of the breast. She had a left modified radical mastectomy, however there was significant post surgery skin deficit. A latissimus dorsi musculocutaneous flap was used to cover the anterior chest wall defect. Sections from the mastectomy specimen confirmed the diagnosis of osteogenic sarcoma. She died six months after mastectomy. CONCLUSION: A diagnosis of osteogenic sarcoma of the breast was made based on histology report and after excluding an osteogenic sarcoma arising from underlying ribs and sternum. This is the second documented case of primary osteogenic sarcoma of the breast coming from Nigeri
