RESUMO

OBJECTIVE: A measles outbreak occurred in S. Paulo state, during 1996 and 1997, resulting in 20,921 cases. Forty seven percent of the cases occurred in people between 20 and 29 years of age, and one of the control strategies of the Department of Health was the vaccination of health care workers. The prevalence of antibodies against measles among the hospital pediatricians was investigated. METHODS: One hundred and fifty samples were taken from volunteer pediatricians to test for measles antibodies using ELISA. A questionnaire about their having had measles and the vaccine was filled out. RESULTS: Of the 150 doctors, 122 (81.4%) were female and 28 (18.6%) male, of between 23 and 46 years of age (mean and median 27 years). The majority (98%-147/150) had protective levels of antibodies against measles (>100 UI/ml); 118 (80.3%-118/147) without and 29 (19.7%-29/147) with a history of measles. Only 3 pediatricians (2%-3/150), had negative serology, 2 without and 1 with a history of measles. Out of the 118 without history of measles, 79 (67%-39/118) in spite of the protective level of antibodies against measles, did not know if they, had been vaccinated. Out of the 79 vaccinated pediatricians, 64 (81%-64/79), had been vaccinated 25 years before, and still maintained protective levels of antibodies. Of the 3 doctors with negative serologies only one declared that he had been vaccinated. CONCLUSIONS: Measles seroprevalence among pediatricians of this hospital is high, especially due to preceding vaccination. On the other hand, the 2% of pediatricians with negative serology, in an epidemic situation could constitute a significant population for the acquisition and dissemination of the disease.

RESUMO

A comparison is made between two groups of children aged 1-24 months and admitted to a teaching University Hospital due to acute diarrhea and severe dehydration. One group (n = 119) received a diluted cow's milk formula and the other (n = 109) a full-strength formula. Duration of diarrhea was similar: In the group that received full-strength milk weight gain was greater during diarrhea (5.03 vs. 1.80 g/kg/day, P < 0.01) and during the hospital stay (5.39 vs. 2.33 g/kg/day, P < 0.001). Weight for height z-scores and weight for height as percentage of median improved during the hospital stay only in the group that received the full-strength formula. Full-strength cow's milk seems to be an adequate routine regimen even for children with acute diarrhea that must be treated for severe dehydration. In developing countries diarrhea and dehydration are a disease of small children. As rates of exclusive breast feeding are low, mainly in the urban setting, cow's milk is the main and sometimes the only food available. Lactose-free formulae are priced out of reach of the poor people and in Latin America there is no accepted tradition for use of fermented milk products. Our study is an indication that use of undiluted cow's milk may be effective for the routine treatment of acute diarrhea in children that must be treated as inpatients due to severe dehydration.

RESUMO

OBJECTIVE: To evaluate the efficacy of dexamethasone as an auxiliary therapeutic tool to the antibiotics in hospitalized children with meningococcal meningitis. METHODS: A retrospective clinical comparative study was undertaken with children from a pediatric ward affected by laboratory proved meningococcal meningitis at a university hospital. Cases of children in state of shock at admission or deceased in the first 24 hours were excluded. During the period from 1987 to 1989 33 children were treated only with antibiotics (group A), while from 1990 to 1993 other 66 children received additionally dexamethasone (12mg/m2/24h) by intravenous route during four days beginning at the admission to the hospital (group B). The two groups were evaluated at baseline through prognostic scores and analysis of their clinical and laboratorial characteristics obtained from data recorded at the admission. The parameters to evaluate dexamethasone efficacy were the comparative number of neurologic and systemic complications detected at the hospital, and the liquoric profile (leukocyte count, glucose and protein content) verified between day 9 and day 11 of hospitalization. RESULTS: The profile of the two groups (A and B) were homogeneously evaluated by the illness severity scores and their clinical and laboratorial characteristics. Nine complications were recognized in group A (27.2%) and 21 (31.8%) among those of group B, difference not significant. Likewise, there were not observed liquoric differences between the two groups related to the chimiocytologic pattern. CONCLUSIONS: No effect of dexamethasone therapy to prevent neurologic and systemic meningococcal meningitis complications was observed during hospitalization. Similarly no favorable effect in relation to the liquoric pattern verified between day 9 and day 11 of hospitalization was recognized.

RESUMO

A laboratory surveillance study was developed in Brazil in 1993 to determine capsular types and antimicrobial susceptibility of Streptococcus pneumoniae strains. By studying 360 strains isolated from children with invasive infections in three different cities, 8 out of 34 types were identified as being the most prevalent and considered as the reference group for further analyses. This group comprised 77.7% of all strains studied, and includes the types 1, 5, 6A/B, 9V, 14, 19F, 19A, and 23F. The prevalence of this reference group was significantly higher among strains isolated from children with pneumonia than meningitis. Similarly, this group was more prevalent among strains isolated from children 3 to 6 years of age than from children under 2 years of age. Most strains (78.6%) were found to be susceptible to penicillin and only 1.4% showed high resistance to this antibiotic. However, intermediate resistance to penicillin was detected in 20% of the strains. This laboratory surveillance will be maintained and extended to other cities of Brazil to better define and monitor the trends of pneumococcal infections for proper control and prevention.

RESUMO

The authors present the case of a child diagnosed as having idiopathic pulmonary hemosiderosis at five years of age who had a good clinical outcome at the age of ten years. Initially the patient was treated with prednisone and chloroquine with poor results. When cyclophosphamide was added to prednisone, the patient demonstrated clinical and radiological remission. To date, the patient has been followed for one year without any medication, and has had only one limited episode of hemosiderosis. The authors also suggest that the therapeutic regimen with cyclophosphamide and prednisone may be useful for some selected cases.

RESUMO

In an open and prospective study involving outpatient children with complicated urinary tract infections (UTI), we evaluated the therapeutic efficacy of ceftriaxone administered intramuscularly, once-daily--50 to 70 mg/kg, during 8 to 10 days. Initially, the selected patients exhibited at least two of the following clinical criteria: age below 6 months, any degree of toxicity, fever, strong suspicion or proved abnormalities of their urinary tracts and lumbar pain in children older than 4 years. Significant bacteriuria was demonstrated by urine culture in 40 patients (21 boys, 19 girls), whose ages ranged from 15 days to 6 years 9 months (median 3 months). The radiological studies revealed vesicoureteral reflux in 6 patients, urethral posterior valve in 1, and neurogenic bladder in 4. The main causative agents were Escherichia coli isolated in 30 patients, Klebsiella (4) and Proteus (4). The treatment was found to be effective in 38 patients (95%). There was failure of treatment in 1 patient and a symptomatic reinfection in another one. It was concluded that children with complicated UTI could be treated alternatively by once daily ceftriaxone.

RESUMO

The authors present five cases of large palatine ulcers of a traumatic nature in infants, with duration from two weeks to four months. Causal diagnosis was difficult at first until the possibility of trauma caused by non-orthodontic nipples (all cases) and dummies (4)--Bednar's aphthae--was considered. Other problems related to sucking were observed: a horizontal position for nursing (all) and very narrow nipple hole (4). The infants' mothers were advised to enlarge the orifice in the nipple and correct the position for nursing (3 cases) and, in addition, to suspend use of a dummy (1 case) and discontinue use of a bottle and dummy (1 case). All of the ulcers healed within a period from one to four weeks. Small scars remained in two of the children.
