Ethiopian teachers: their knowledge, attitude and practice towards epilepsy.

BACKGROUND: In Ethiopia where the burden of epilepsy is highest among school age children and teenagers, and where people with epilepsy (PWE) and their relatives suffers from high level of perceived stigma, there had not been any study that assessed the knowledge, attitude and practice of teachers towards PWE. This study aims to assess and understand the social and demographic determinants of knowledge, attitude and practice of teachers towards PLW in Addis Ababa, Ethiopia. METHODS: Multistage cluster sampling procedure was used to identify twenty schools from three sub cities of Addis Ababa, Ethiopia. Standardized self administered questionnaire was used to collect data from 845 volunteer teachers in the pre identified schools. Frequencies were used to characterize the demographic variables while multiple response frequencies were used to characterize the multiple response variable sets. Non-parametric statistical methods were used to describe the association among the demographic variables of interest and the count sums of multiple response variables which were grouped into biologically and culturally plausible responses. RESULTS: The most common biologically plausible responses were: brain diseases (26.5 %) from causes, allow my offspring to play with PWE (19.1 %) from attitude, protect the subject from injury (20.4 %) from first aid measures and seek help from medical doctors (52.2 %) from epilepsy treatment. On the contrary, the most common culturally plausible responses were: psychiatric illness (12.9 %) from causes, epilepsy be cured before attendance to school (21.6 %) from attitude, smelling the smoke of struck match (14.2 %) from first aid measures and Holy water treatment (20.3 %) from epilepsy treatment suggestions. The biologically and culturally plausible responses were negatively correlated. Level of education was positively associated with biologically plausible responses while teaching experience was negatively correlated with culturally plausible responses. CONCLUSION: A high percentage of teachers in Addis Ababa considered epilepsy as a psychiatric illness closely linked to insanity. This explains their suggestions of Holy water treatment and Church healing sessions as epilepsy remedies. This is in agreement with Ethiopian culture, in which evil spirit and insanity are believed to be better treated by religious remedies than with modern medical treatments. Incorporating special needs educational training courses in the curriculum of teachers training may help them shift their knowledge, attitudes and practices from that of the culturally plausible to biologically plausible one.

Lead levels in primary teeth in children from urban and rural areas in Ethiopia.

BACKGROUND: Lead (Pb) is one of the most important and widely distributed pollutants in the environment. Lead concentration in human primary teeth reflects children's exposure to the metal during early life. OBJECTIVE.: In this study we wanted to get preliminary information of the level of lead exposure in Ethiopian children in rural as well as urban areas. METHODS: Primary incisors, exfoliated 1998-2000, were collected from Addis Ababa, the capital, and two rural villages in the Rift Valley. The teeth were analyzed for lead concentrations by graphite furnace atomic absorption Spectrophotometry. RESULTS: Very high lead concentrations were not found. However, teeth from Addis Ababa had statistically significant higher lead concentrations than teeth from the Rift Valley. Teeth from both villages showed very low Pb-concentrations, but one village (Village A) had significantly higher concentrations than the other (Village K). The living conditions of the two villages were similar, the main diference being the fluoride content of the drinking water. The village with the lowest tooth-lead had the highest fluoride concentration. CONCLUSION: Our findings indicate that child lead exposure in Ethiopia is relatively low, especially in the rural populations.

No evidence for prolonged excretion of polioviruses in persons with residual paralytic poliomyelitis in Ethiopia, Pakistan and Guatemala.

Persons who have developed acute flaccid paralysis following infection with wild-type polioviruses or vaccine-associated paralytic poliomyelitis usually excrete polioviruses for only a few weeks. However, some patients with paralytic poliomyelitis have had prolonged excretion of polioviruses for periods of up to 10 years after onset of disease. Most prolonged excretors have been identified in industrialized countries. We studied 348 patients 2-28 years old in Ethiopia, Pakistan and Guatemala with residual paralytic poliomyelitis to determine if they had IgA or IgG deficiency or persistent poliomyelitis excretion at least 1 year after onset of disease. None of the 348 affected individuals had IgG deficiency or persistent poliovirus excretion. One child had borderline low serum IgA concentration. Since we did not study children under 2 years of age, persons born with IgG deficiency disorders may have died in developing countries where replacement immunoglobulin therapy is not readily available. Nevertheless, persistent poliovirus excretion among persons 2 years of age and older with residual paralytic poliomyelitis is uncommon in developing countries.
