A successful, preventive-oriented village health worker program in Hebron, the West Bank, 1985-1996.

Village health rooms (VHRs) were established in villages with no on-site health facilities in the Hebron District of the West Bank, beginning in 1985. By 1991, the program served a total population of 40,000 in 49 VHRs and by the end of 1996 covered 69 villages in Hebron and 20 in other districts that were previously served by visiting vaccination teams and nearby clinics. The VHRs provide close contact with the population of mothers for well child and pregnancy care, health education and provide visiting doctor/nurse teams for backup services and supervision. Data on coverage, utilization, costs, and outcome measures are presented. The program is accepted and grows despite adverse social and political conditions.

Subacute sclerosing panencephalitis presenting as acute disseminated encephalomyelitis: a case report.

Subacute sclerosing panencephalitis is characterized by the insidious onset of diffuse cerebral dysfunction associated later with myoclonus and typical electroencephalographic changes. The disease progresses relentlessly to coma and death within 2 years. We report a case of acute onset and rapid course associated with atypical CSF, EEG and MRI features simulating acute disseminated encephalomyelitis. Brief review of relevant literature is presented.

Cytokine changes in patients with heatstroke during pilgrimage to Makkah.

Circulating levels and role of IL-6, IL-1ra, TNFsr-II and CRP in patients with heatstroke is not fully known. This study correlated levels of these mediators with outcome in 26 patients. In survivors (n=20), IL-6 concentration declined on cooling, whereas in non-survivors levels continued to increase at 6 h following admission before declining. Admission TNFsr-II concentrations in survivors were significantly lower than non-survivors and levels continued to rise in both groups. IL-1ra levels were markedly elevated in both groups. Changes in cytokine levels were not influenced by renal function. Elevated C-reactive protein levels were observed for both groups and remained so despite cooling, furthermore, there was no correlation with alanine aminotransferase levels. The study demonstrated the elevation of the above mediators and suggested a role in the pathogenesis of heatstroke. Markedly elevated levels or those that remained elevated despite cooling were associated with mortality.

Efficacy and safety of once-daily amikacin in combination with ceftazidime in critically ill adults with severe gram-negative infections.

Forty critically ill adult patients with severe Gram-negative infection were treated with once-daily amikacin combined with ceftazidime. The mean age was 56.6 +/- 19 years and mean APACHE II score was 22.7 +/- 6.6. Forty percent of patients required mechanical ventilation. The mean creatinine clearance at onset of therapy was 59.4 +/- 28 ml/min. All bacterial isolates were sensitive to amikacin. Fixed doses of amikacin 15 mg/kg, 12 mg/kg, and 8 mg/kg body weight were given once daily to patients with estimated creatinine clearance of > 80 ml/min., 50-80 ml/min., and < 50 ml/min, respectively. Forty-two causative gram-negative bacteria were isolated from 40 patients. The most common bacteria were Pseudomonas aeruginosa (18), and Escherichia coli (10). Overall clinical success and bacteriological eradication occurred in 85% and 87.5% of patients; 78.9% and 79% of patients with hospital-acquired infections; 90.5% and 95.2% of patients with community-acquired infections; and 62.5% and 81.3% of patients requiring mechanical ventilation, respectively. Therapeutic failure was documented in 15% of patients. Death due to infection was scored in two patients. The remaining were all due to persistence of the initial causative bacteria in patients with hospital-acquired infections. Persistence was documented with Ps. aeruginosa (2), Serratia spp. (1), and Acinetobacter spp. (1). Overall mortality occurred in 22.5% patients. Death unrelated to infection occurred in 7 patients. There was no clinical evidence of ototoxicity in any of our patients, however, nephrotoxicity was documented in 5%. In conclusion, once-daily amikacin combined with ceftazidime is practical, efficacious and probably safe in critically ill infected patients.

Tuberculosis presenting as immune thrombocytopenic purpura.

Various haematological abnormalities commonly occur in active tuberculosis (TB). However, thrombocytopenia is rare and immune thrombocytopenic purpura (ITP) is mentioned only in few case reports. We found that of 846 cases with active TB, 9 (1%) presented with ITP as the only abnormality. Three out of these 9 cases had disseminated miliary TB, 3 an abdominal abscess or lymphadenitis, and 3 pulmonary TB; none had palpable splenomegaly. All patients had purpura and the platelet count varied between 4 and 21 x 10(9)/l, and the bone marrow showed increased megakaryocytes. All tuberculous patients showed initially a poor platelet count response to steroid therapy. The platelet count returned to normal 2-6 weeks after oral prednisone combined with antituberculous drugs.
