Refractive errors in Kaduna, Nigeria
T Bagaiya, V Pam
Nigerian Journal of Surgical Research , 2003,
Abstract: Background: In the face of economic decline in Nigeria, budgetary subvention from government to health institutions has suffered adversely. Health institutions are forced to look inwards, minimize waste and generate resources to sustain clinical services. One such area of clinical service is the optical area. To sustain this important service area, the need to identify common refractive error and to commit meagre resources to the purchase of appropriate lens category became imperative. Methods: Between February 2000 and February 2001, a prospective study on the pattern of refractive errors was carried out at the outpatient eye clinic of the Guinness Ophthalmic Unit, Kaduna. Every consecutive new patient with asthenopic symptoms or blurred vision for distant objects or for small prints was refracted. Results: One thousand eight hundred and forty one patients with asthenopic symptoms were refracted. Forty nine percent were males and fifty one percent females. The age range was 6 – 60 years. Low-grade hypermetropia (0.25D – 1.25D) was the commonest spherical error (21.7%) observed, while astigmatism was observed in 14.3%. simple myopia constituted 8.0%. Presbyopic patients formed the largest group (56.0%). Conclusion: Refractive error is a common cause of visual impairment among ophthalmic patients in Kaduna. Judicious management of the meagre resources on appropriate lens category, which in this study is presbyopic lens type, cannot be overemphasized.

Abstract: The adsorption of Cr (III) ion from aqueous solution using orange peels as adsorbent was investigated using batch equilibrium technique. The research is significant as it’s aimed at investigating the suitability of orange peel, a waste product as adsorbent for the adsorption of Cr (III) ions from aqueous solution. Orange peel as an adsorbent is resource-saving and has an environmental friendly behavior. Adsorption envelope experiment was conducted using a constant Cr (III) ion concentration of 0.1 M, adsorbent dose of 2.5 g and a temperature of 30°C at varying solution pH of 2, 4, 7, 9 and 12 respectively with pH of 2 having the highest adsorption and therefore it was selected for use in the adsorption isotherm experiment. Adsorption isotherm experiment was conducted at varying temperatures (30°C, 40°C, 50°C, 60°C), concentration (0.1 M, 0.2 M and 0.3 M) Cr(NO3)3. Thermodynamic parameters such as ΔG, ΔH, ΔHr, ΔA, and ΔS were calculated from the experimental data which showed that the adsorption process is feasible, spontaneous and followed physisorption mechanism 9H2O and adsorbent dosage (1 g, 1.5 g and 2 g) respectively. The experimental results were tested using Langmuir, Freundlich, Linear and Temkin adsorption isotherm models. The experimental data best fitted the Freundlich isotherm model. The experimental results revealed the suitability of orange peel which is a waste product as effective adsorbent for the sorption of chromium (III) ions from aqueous solution.

Nigerian Journal of Surgical Research , 2005,
Abstract: Background: Five public primary schools referred to as Local Education Authority (L.E.A.) primary schools, were identified for this study. The aim was to find out the pattern of eye disorders affecting primary school children in Kaduna North metropolis and to offer treatment to those with treatable disorders. Method: A total of 2,397 pupils whose classes ranged from primary one to six and aged between five to eighteen years were examined. Results: Of this number, 1,232 (51.57%) were males and 1,161 (48.43%). The commonest causes of eye disorders were allergic conjunctivitis (14.5%), refractive error (1.7%), and infective conjunctivitis (1.4%). Conclusion: School eye screening visits should be at least once a year and should involve screening of all nursery one and primary one pupils. School teachers can be trained to measure visual acuity. Primary eye care workers may be trained and utilised to carrying out school screening in schools, while basic eye health classes can be taught in ante-natal classes to enlighten mothers who are the primary care givers. Early detection of eye conditions in children is an advantage for management. Nigerian Journal of Surgical Research Vol. 7(1&2) 2005: 191–194

Abstract: Purpose: Microsporidial infections have been recognized as an increasingly important infection in immuncompromised patients, particularly those infected with HIV/AIDS. This study was designed to study immune responses associated with experimental Encephalitozoon intestinalis infection in immunocompetent rats. Materials and Methods: Thirty-four Rats in 3 groups, A (Control), B (Intraperitoneal) and C (Oral) were given injections of 0.5 ml of 2 x 10 6 of purified spores of Encephalitotozoon intestinalis spores and were observed for serum specific IgG for 21 days using both direct and indirect ELISA. Results: In indirect ELISA, specific lgG were detected on days 7, 14 and 21 for the group B rats and on day 21 for group C and in direct ELISA method, specific lgG were detected in-group B rats on days 7 and 21, for group C rats on day 21 only, while in the control rats, specific lgG were not detected. There was no significant difference between the direct and indirect methods (df=1, X 2 , P>0.05). E. intestinalis was observed in stool samples of rats in 1/12 (08.33%) on days 14 and 21 in group B, and in 4/10 (33.33%), 3/10 (25.00%) and 2/10 (16.67%) on days 7, 14 and 21 respectively in group C. In group A, which is the control rats, no microsporidia were observed on days 0, 7, 14 and 21. Conclusions: There were no changes in the T-lymphocyte counts of rats prior to and after inoculation with spores. Extensive lesions were observed along the intestinal walls especially on the middle and lower sections of group C rats only.
Using the Ages and Stages Questionnaire to teach medical students developmental assessment: a descriptive analysis

Abstract: To evaluate the program, an interpretative analysis was completed on the students' reports written during the program and a questionnaire was administered to the parents to gain their perception of the experience. As well, student confidence levels in assessing growth and development were measured at the end of the paediatric term.Although there was an increase in student confidence in developmental assessment at the end of the term, it was not statistically significant. However the findings indicated that students gained increased understanding of the process and enhanced recognition of the parental role, and the study suggested there was increased confidence in some students. Parents indicated that they thought they should be involved in the teaching of students.The ASQ was shown to have been useful in an education program at the level of advanced beginners in developmental assessment.Developmental assessment is a core learning outcome for paediatric and child health students, so when a survey of medical graduates' skills identified a lack of confidence in this area, a program was developed with the aims of increasing both confidence and respect for the parental role. This study evaluates that program.Paediatric and child health practitioners advocate a family-centred care model that requires practitioners to have good interpersonal skills, to have respect for parental judgement and to be flexible in their role [1]. As well, collaborative patient-centred practice is emerging as a framework for interdisciplinary education [2]. For these frameworks to be successful, interpersonal competence, which includes an appreciation of the skill and uniqueness of all individuals involved, is required [3]. The development of these attitudinal and communication attributes in health care practitioners is one of the challenges for health educators interested in family-centred practice.Medical student attitudes are important because they are viewed as a mediating link between clini

Thinking globally, acting locally: Women activists’ accounts
Alldred Pam
Temida , 2003, DOI: 10.2298/tem0304023a
Abstract: This paper intends to describe the range of forms women’s resistance to globalisation takes, emphasising diverse strategies from everyday acts, the development of practical alternative resources, organising in women’s groups or trades unions, mass demonstrations and symbolic defiance. Recognising that it is the women of the South, in particular, who bear the brunt of the impact of neoliberal ‘free market’ economic policies, it hoped to be sensitive to the struggles for survival that might frame the urgency of resistance amongst women of the South, and make links with some of the strategies of activist women in the more privileged North.
