Medical relief operation in rural northern Ethiopia: addressing an ongoing disaster.

BACKGROUND: Following the recent drought in Ethiopia, the Jewish Agency, aided by the Israel Ministry of Foreign Affairs, launched a medical relief mission to a rural district in Ethiopia in May-August 2000. OBJECTIVES: To present the current medical needs and deficiencies in this representative region of Central Africa, to describe the mission's mode of operation, and to propose alternative operative modes. METHODS: We critically evaluate the current local needs and existing medical system, retrospectively analyze the mission's work and the patients' characteristics, and summarize a panel discussion of all participants and organizers regarding potential alternative operative modes. RESULTS: An ongoing medical disaster exists in Ethiopia, resulting from the burden of morbidity, an inadequate health budget, and insufficient medical personnel, facilities and supplies. The mission operated a mobile outreach clinic for 3 months, providing primary care to 2,500 patients at an estimated cost of $48 per patient. Frequent clinical diagnoses included gastrointestinal and respiratory tract infections, skin and ocular diseases (particularly trachoma), sexually transmitted diseases, AIDS, tuberculosis, intestinal parasitosis, malnutrition and malaria. CONCLUSIONS: This type of operation is feasible but its overall impact is marginal and temporary. Potential alternative models of providing medical support under such circumstances are outlined.

Acinetobacter baumannii at a tertiary-care teaching hospital in Jerusalem, Israel.

In a retrospective 10-year analysis of 3,536 patient-unique isolates, Acinetobacter baumannii imipenem susceptibility declined from 98.1 (1990) to 64.1% (2000), and ciprofloxacin susceptibility decreased from 50.5 to 13.1%. Imipenem median zone diameters decreased from 27. 7 (1997) to 18.8 mm (2000). No outbreaks were detected. Two clusters were identified for 41 strains genotyped by pulsed-field gel electrophoresis, but imipenem resistance was not clonal.

Hepatitis A associated with other focal infections.

BACKGROUND: Concomitant bacterial and viral infection is a well-known phenomenon, however only very rarely has a bacterial infection been reported during hepatitis A virus infection. OBJECTIVE: To evaluate retrospectively the clinical records of children hospitalized with HAV infection for a concomitant infection proved or presumed to be bacterial. METHOD: A retrospective study was conducted on all the children hospitalized with hepatitis A infection from 1988-96 in our center. The records were evaluated for a concomitant infection. RESULTS: Of 40 children hospitalized with HAV infection, 13 were found to have a concomitant infection: these included 6 with pneumonia, 4 with pyelonephritis and 1 case each of purulent otitis media, osteomyelitis and staphylococcal bacteremia. CONCLUSION: In areas where hepatitis A is endemic, a simultaneous infection with hepatitis A and other common bacterial infection during childhood may co-exist. A permissive role for HAV infection is suggested.

The clinical course of bronchiolitis associated with acute otitis media.

BACKGROUND: Acute otitis media (AOM) is the most common bacterial co-infection of viral bronchiolitis. AIMS: To evaluate the influence of AOM on the clinical course of bronchiolitis. SUBJECTS: 150 children younger than 24 months old, diagnosed with bronchiolitis, hospitalised between December 1997 and May 1999. METHODS: Body temperature, respiratory rate, oxygen saturation, and the need for oxygen supplementation were recorded on admission and daily throughout hospitalisation. Complete blood count, erythrocyte sedimentation rate, and assay for respiratory syncytial virus were performed on admission. All children were examined daily for the appearance of AOM. The clinical course of children with bronchiolitis and AOM was compared to those without AOM. RESULTS: AOM was diagnosed in 79/150 (53%) children with bronchiolitis. Most were diagnosed within the first two days of hospitalisation. No significant difference was found in the clinical and laboratory findings on admission and on daily follow up between children with and without AOM. CONCLUSIONS: This 2.5 year prospective study showed no difference in the course of bronchiolitis, whether an ear infection was present or not.

A nationwide prospective surveillance study in Israel to document pediatric invasive infections, with an emphasis on Haemophilus influenzae type b infections. Israeli Pediatric Bacteremia and Meningitis Group.

BACKGROUND AND METHODS: An ongoing nationwide prospective surveillance study was initiated in Israel in October, 1988, to document childhood invasive infections caused by Haemophilus influenzae type b (Hib), Streptococcus pneumoniae and Neisseria meningitidis. This study enabled us to document the effect on childhood invasive Hib disease of the introduction of conjugate Hib vaccines to Israel. RESULTS: The incidence of invasive Hib disease before the age of 5 years dropped from 34 per 100000 before initiation of immunization to < 5 per 100000 in 1995 and is projected to be <4 in 1996. After <2 years, when various conjugate vaccines had been available in the private sector alone and had achieved partial coverage only, the Israeli Ministry of Health decided to add Hib conjugate vaccine to the regular infant immunization program, free of charge, effective for all infants born after January 1, 1994. The vaccine chosen was Hib polysaccharide linked to outer membrane protein complex of N. meningitidis B. Vaccine coverage has exceeded 90% of all infants born since January 1, 1994. Efficacy and effectiveness during the first 34 months of the program (January 1, 1994, to October 31, 1996) were 95.4 and 99.7%, respectively, for all invasive Hib disease and 97 and 99.4%, respectively, for Hib meningitis. CONCLUSION: The described ongoing surveillance program showed the existence and extent of Hib problems in Israel and documented the success of the immunization program in essentially eliminating the disease in Israel.

Treatment with hypertonic saline versus normal saline nasal wash of pediatric chronic sinusitis.

BACKGROUND: Chronic sinusitis (CS) is a common disease in children, especially those with allergies, that is caused by impaired drainage from the sinuses. Hypertonic NaCl solution has been shown to increase mucociliary clearance and ciliary beat frequency. OBJECTIVE: We performed a randomized double blind study to compare the effect of nasal wash with hypertonic saline (HS) (3.5%) versus normal saline (NS) (0.9%) on CS. METHODS: Thirty patients with CS aged 3 to 16 years were studied. They were randomly divided into two treatment groups matched by age and severity of the disease. Each individual was treated with either HS or NS for 4 weeks. All patients were evaluated by two clinical scores (cough and nasal secretions/postnasal drip [PND]) and by a radiology score at the beginning of the study and after 4 weeks. RESULTS: The HS group improved significantly in all scores (average +/- SD): cough score, from 3.6 +/- 0.51 to 1.6 +/- 0.74; nasal secretion/PND score, from 2.86 +/- 0.35 to 1.6 +/- 0.74; and radiology score, from 8.06 +/- 1.28 to 2.66 +/- 1.04. The NS treatment group showed significant improvement only in the PND score (from 2.66 +/- 0.49 to 1.53 +/- 0.83) but no significant change in both the cough score (from 3.53 +/- 0.52 to 3.33 +/- 0.49) and the radiology score (from 8.13 +/- 1.25 to 7.86 +/- 0.91). Clinical observation 1 month after the end of the study showed no change compared with the end of the study in both groups. CONCLUSION: HS nasal wash is an efficient treatment of CS.

Focal bacterial nephritis (lobar nephronia) in children.

We report 13 patients with 16 episodes of acute lobar nephronia diagnosed in a prospective study that was conducted among 210 hospitalized children with urinary tract infection. In 30 episodes of urinary tract infection, a hypoechogenic or hyperechogenic lesion was found. Twenty patients underwent computed tomography, and in 16 of them acute lobar nephronia was diagnosed. Evolution to renal abscess occurred in 25%. Prolonged intravenous antibiotic treatment was sufficient in all cases.
