Basic development needs approach in the Eastern Mediterranean Region: from theory to practice.

Poverty and health are mutually reinforcing and deprivation in one area produces negative effects in the other. Unfortunately at the beginning of the 21st century, the number of people living in absolute poverty continues to rise with grim health consequences. Many studies have clearly established that health is related to and influenced by a complex of environmental, social and economic factors ultimately related to each other. Therefore, actions undertaken outside of the health sector are likely to have effects much greater than those obtained through the health sector alone. Thus, the countries of the World Health Organization Eastern Mediterranean Region have adopted basic development needs to address all the determinants of health collectively through community empowerment in order to transform social lifestyles and enhance human development. This article presents the contribution made by basic development needs in empowering local communities and vulnerable groups to acquire their essential needs through the efficient use of available resources. The assessment surveys of the ongoing programme conducted periodically in different countries have demonstrated significant reduction in poverty levels and improvement in quality of life indices pertaining to a wide range of fields, including health, nutrition and other social sectors.

Female health workers boost primary care.

Women residing in villages in three districts of Pakistan were recruited, trained to deliver primary care and mobilize their communities for health, assigned to limited catchment areas, provided with supervisory and managerial support, and remunerated. Their comprehensive activities substantially reduced infant, child and maternal mortality within a year and generated positive perceptions of family planning in the communities. The programme was cost-effective and appeared suitable as a model for reforming the organization and provision of health care services.

Studies on the antimicrobial activity of honey.

Ten samples of crude and processed honey were used to determine antimicrobial activity against twenty five species of pathogenic and nonpathogenic bacteria, commonly encountered in human infections. The antifungal activity was checked against ten parasitic and saprophytic fungi. Most of the samples of honey used in the study showed broad spectrum antibacterial and promising antifungal activity.

Seven-day viable analysis of some ophthalmic preparations with different concentrations of benzalkonium chloride.

The efficacy of zinc sulphate and boric acid ophthalmic preparations, containing benzalkonium chloride as preservative have been investigated against Gram-negative Escherichia coli and Pseudomonas aeruginosa and Gram-positive Staphylococcus aureus bacteria. The viability of bacteria was checked after 7 days though they were completely suppressed after 24 hours of inoculation. Zinc sulphate increased the antimicrobial activity of benzalkonium chloride, whereas the boric acid or its combination with zinc sulphate reduced the same. The Pseudomonas aeruginosa was found to be viable against zinc sulphate, boric acid or its combination at a concentration of 0.01% to 0.005% of the preservative. Escherichia coil and Staphylococcus aureus also exhibited resistance but to a lesser extent than Pseudomonas aeruginosa. This viability may be dangerous in case of multidose ophthalmic preparations.

Therapeutic efficacy of ACTH in symptomatic infantile spasms with hypsarrhythmia.

The records of twenty-six infants with both symptomatic infantile spasms and classic hypsarrhythmia were reviewed to determine the efficacy of various ACTH dosages and time of initiation of therapy. Mean age of infantile spasm onset was 6.4 months. Most patients (13) had sustained perinatal hypoxic-ischemic insults. Seventeen patients (65%) had complete cessation of spasms. Between these responders and the 9 nonresponders there was no difference in duration of spasms prior to treatment (2.6 and 2.0 months) or mean ACTH dose (87.4 and 84.5 U/m2, respectively). Infants treated with high-dose ACTH (> 100 U/m2) did not have an improved response rate. The most favorable outcomes were associated with spasm onset at > 8 months of age (all of whom were responders, regardless of dose) or when treatment was started within 1 month of onset of infantile spasms with > 80 U/m2 ACTH (88% responders). Infants treated more than 2 months after onset often did not respond (57%) regardless of dose. Nonresponders with spasm onset at < 4 months of age had the worst prognoses; all had poorly controlled seizures and regressed developmentally. Although all infants in the study were neurologically abnormal, development either improved or did not deteriorate in most responder infants following spasm resolution and one-half remained seizure free. Nonresponder infants continued to have infantile spasms or other seizure types. These data suggest that ACTH is valuable in the treatment of significantly impaired infants with symptomatic infantile spasms, but the most important determinants of outcome may be age of onset and rapidity of treatment rather than dosage.
