Age-specific seroepidemiology of hepatitis A, B, and E infections among children in Istanbul, Turkey.

This study was performed for evaluation of seroprevalence of hepatitis A, B, and E among children in Istanbul, Turkey. The study group included 909 children who were 6 months-15 years of age. The children were separated to three age groups: Group 1 (6 months-4.9 years; n = 321), Group 2 (5.0-9.9 years; n = 318), and Group 3 (10.0-15.0 years; n = 270). Group I was divided to two subgroups for evaluation of the maternal antibody sera (6 months-2 years and over 2 years). Serum IgG anti-HAV, anti-HBc, and anti-HEV were tested by commercial ELISA kits. The data were studied by multivariant analysis. In all subjects, seroprevalence of hepatitis A, B, and E were determined as 29, 15.9, and 2.1% respectively. The prevalence of hepatitis A increased with age (p < 0.05; Group 1 15.1% and Group 3 49.6%). Anti-HBc IgG level did not significantly change with age (Group 1 18.6% and Group 3 15.4%; p > 0.05). The seroprevalence of hepatitis E virus infection was higher in Group 1 (3.7%) than Group 3 (0.3%; p < 0.05). In Group 1 first subgroup, between 6 month and 2 year, antibody levels were 12.2, 17.3, and 4.8% respectively, for anti-HAV IgG, anti-HBc IgG and anti-HEV IgG. Hepatitis A and B infection is a community health problem, but hepatitis E infection is low in children in Istanbul, Turkey. The high positive rate in Group I for IgG anti-HEV may be due to maternal antibodies.

Genes of major histocompatibility complex class II influence chronic C hepatitis treatment with interferon in hemodialysis patients.

UNLABELLED: The prevalence of anti-HCV among patients on hemodialysis is consistently higher than in the general population, indicating that patients on hemodialysis programs are at risk of acquiring HCV infection. The response to interferon alpha 2b (IFN -alpha 2b) therapy in chronic C hepatitis depends on viral and host factors. We treated 22 chronic C hepatitis uremic patients with IFN -alpha 2b (3 MU three times a week) and compared interferon responsive and unresponsive patients with regard to HLA II genes. HLA II genes were investigated by PCR-SSP low resolution, anti-HCV with ELISA II and HCV-RNA with reverse transcriptase "nested" PCR. FINDINGS: HLA DRB1*13 is 50% positive in the non-responder group (four women, four men, mean age; 28.8+/-11.9 years) and 7% in the responder group (five women, nine men, mean age; 32.2+/-7.8 years) (p<0.05). There was no difference with respect to HLA genes between controls (six women, eight men, mean age; 29.5+/-12.8 years) and patients (nine women, 13 men, mean age; 31.0+/-9.3 years) (HLA DRB1*13 is 28% and 22% positive, respectively). We conclude that major histocompatibility complex class II genes influence the outcome of chronic C hepatitis treatment with IFN -alpha 2b.

Airway foreign bodies in childhood.

OBJECTIVE: To define clinical spectrum of airway foreign body aspiration in children and to evaluate the outcome and complications. METHODS: A total of 53 patients (27 girls, 26 boys) with a mean age of 30.0+/-32.7 months, who aspirated foreign bodies were treated with bronchoscopy were divided into two groups with respect to the time they were diagnosed as early (Group 1, n=22, </=24 h after aspiration) and late diagnosed group (Group 2, n24 h after aspiration). The two groups were followed up prospectively for complications. RESULTS: A total of 72% of patients were under a 3-year age group. Choking episode history was reported in 32% of patients but when families were questioned about it more in detail the rate increased to 51%. Acute episode of choking seemed trivial most of the families. Cough (69.8%), decreased breath sounds (52.8%) and wheezing (45.1%) were predominant symptoms. Sunflower seed (32. 1%) and peanuts (15.1%) were noted as common aspirated materials. Air trapping (59%) and consolidation (47%) were the most frequent radiological findings especially in the late diagnosed group (P<0. 01). Patients who aspirated organic materials frequently developed pneumonia diagnosed in late period after aspiration. CONCLUSION: Pediatricians must be conscious to check for foreign body aspiration who have sudden onset of cough and wheezing episode. In any suspicion, a bronchoscopy should be considered even if there is not any positive history for aspiration. Children should be followed up after bronchoscopy for complications.

Corticosteroid treatment of childhood Bell's palsy.

The therapeutic effect of corticosteroids in acute idiopathic peripheral nerve paralysis (Bell's palsy) in children is controversial. The authors evaluated the effect of steroids on the early and late outcome of children with Bell's palsy in a prospective randomized controlled setting. Forty-two patients (21 females, 21 males) with complete paralysis were enrolled in the study. Group 1 (n = 21) received methylprednisolone (1 mg/kg daily for 10 days orally); Group 2 (n = 21) did not. All patients were observed in the first 3 days of the disease and at 4, 6, and 12 months of follow-up. The mean age of Group 1 was 52.4 +/- 4.3 months, not significantly different from that of Group 2. In Group 1, 86% and 100% exhibited normal nerve function at 4 and 6 months of follow-up, respectively; in Group 2, 72% and 86% demonstrated complete recovery at 4 and 6 months, respectively, with improvement in all patients by 12 months. The improvement rates between the treated and untreated groups did not differ significantly. No side effects necessitated steroid withdrawal. The results of this study indicate that steroid therapy initiated at an early stage of childhood Bell's palsy does not significantly improve the outcome.

Coexistence of VATER association and recurrent urolithiasis: a case report.

VATER association is diagnosed by the combined presence of at least three of the following features: vertebral anomalies, anal atresia, tracheo-esophageal fistula and/or esophageal atresia, radial ray anomalies, and renal anomalies (53%). Urolithiasis has not been reported in this syndrome. A 4-month old girl presented because of irritability, and the presence of stones in the diapers. Physical examination revealed anal atresia for which colostomy was performed in the newborn period. The diagnosis of VATER association was established by the additional findings of hemivertebrae, sacral dysgenesis, and horseshoe kidney which was partly non-functional. Urinary pH was repeatedly below 6. An excreted stone consisted of pure uric acid. Metabolic investigations detected no specific pathology in purine metabolism. Urolithiasis did not recur after reconstructive anal and anorecto-vaginoplasty, implying that it was a consequence of colostomy and/or of the underlying renal anomaly. We suggest that after colostomy patients with VATER association should be followed for possible urate stones, e.g. by regular screening of urinary pH.

Trial of co-trimoxazole versus procaine penicillin G and benzathin penicillin + procaine penicillin G in the treatment of childhood pneumonia.

This study, which aimed to assess the results of three different regimens in the treatment of pneumonia, was carried out at the Pediatric Outpatient Department of Capa Children's Hospital in Istanbul on 151 patients aged between 4 months and 14 years. The first group (n = 46) received co-trimoxazole orally for 10 days and the second group (n = 63) procaine penicillin G in intramuscularly for 10 days. Benzathin penicillin G combined with procaine penicillin G was given to the third group (n = 42) as a single dose intramuscularly. While the best results were obtained with penicillin procaine G, no statistically significant difference was found between this regimen and co-trimoxazole therapy (chi 2 = 0.305023 P = 0.5). We suggest that co-trimoxazole is easy to administer and cost effective in the ambulatory treatment of pneumonia in children.

The impact of systematic use of oral rehydration therapy on outcome in acute diarrheal disease in children.

A review of our experience with diarrheal disease (DD) at the University of Istanbul Children's Hospital in Capa, covering the years 1987 to 1989, is presented in this paper. DD is one of the most common conditions encountered among patients presenting to the outpatient clinic (5.9% of all cases). The majority of DD cases were in the four- to 12-month age group. During the surveillance period, summertime peaks in DD were observed, suggesting an increase in bacterial infection. Out of 8749 cases of DD, 5.2% showed severe dehydration. Rates of hospitalization for DD did not show any differences over the three years. However, mortality from DD significantly decreased from 1.15 to 0.57% during this three-year period. This was attributed to more rational use of oral rehydration solutions, as a result of the close monitoring and recording of findings introduced by the protocol of this study. Malnutrition, sepsis, pneumonia, and other severe systemic diseases were found to be the most important risk factors affecting hospitalization and mortality rates. Infants, especially those under three months, had the highest risk for hospitalization and mortality.

Experience with diarrheal disease in a university pediatric hospital.

In 1987, 3227 diarrhea cases, half of which were infants, presented at the Out-patient Department of the Istanbul University Children's Hospital. An examination of these cases showed that in 1,066 cases diarrheal disease (DD) was accompanied by a coexisting infection or other disease. The cases with severe dehydration, shock or severe systemic disease were immediately hospitalized. All the remaining cases were administered oral rehydration therapy (ORT) in the Diarrhea Unit, and 94.7 percent of them were successfully rehydrated with ORT. Severe dehydration, shock, severe systemic infection, abdominal distention, failure of rehydration by the enteral route, severe protein energy malnutrition (PEM), and the presence of convulsions were the indications for i.v. therapy. The overall mortality rate was 11 percent. Our experience with DD indicates that widespread implementation of ORT in diarrheal disease and the establishment of Diarrhea Units in large hospitals will contribute not only to saving more lives but will also have an economic impact by reducing the number of admissions.

Analysis of measles cases in a university pediatric hospital during 1988 and 1993 outbreaks.

In Turkey, a mass measles immunization campaign was initiated in 1985, and the decision was made to administer the first of the measles vaccinations at nine months of age instead of 12-15 months. Following the campaign there was a decrease in the number of measles cases seen in the Outpatient Department of Istanbul University Children's Hospital in 1986 and 1987; however, after 1987 an increase was observed in measles cases, which continued until 1993. In order to investigate the current measles epidemics, we reevaluated the measles cases seen in our Outpatient Department from 1986 to 1993. We also investigated the vaccination status and the hospitalization and mortality rates of measles cases in the epidemics of 1988 and 1993. Since 1988 (except 1989) a significant increase (412-1375 percent) has been observed in measles cases, and between 1986 and 1993 more than half of all measles cases were in children older than four years of age. In 1988 and 1993 we found that most vaccinated measles cases were also in this age group, but the rate of complications and hospitalization among the vaccinated cases was lower compared to those who were not vaccinated.

A case of brachyolmia.

Brachyolmia refers to a form of skeletal dysplasia characterized by general platyspondyly without significant epiphyseal, metaphyseal or diaphyseal changes in long bones. Three, possibly four, types of brachyolmia have been defined: Type I-Hobaeck-Toledo type. Type II-Maroteaux and Type III. We report a patient with brachyolmia and present the clinical and radiological findings. A 15-year-old boy presented to our Outpatient Department because of his short stature. His height, weight, head circumference and arm span were 127 cm (< 3rd percentile), (3rd percentile) 39 kg, 55 cm (50th-75th percentile), and 142 cm respectively, and his upper segment/lower segment ratio was 0.91. His neck and trunk were short. He had severe kyphoscoliosis. Slit-lamp examination was normal. Radiologic features included platyspondyly in cervical, thoracic and lumbar vertebrae as well as kyphoscoliosis. Bilateral coxa valga and mild acetabular irregularities were noticed on pelvic radiographies. Levels of chondroitin and heparan sulphate as well as the glycosaminoglycan/creatinine ratio were elevated in the 24-hour urine specimen. The activities of N-acetylgalactosamine-6-sulphatase, beta-galactosidase and beta-hexosaminosidase were all normal in fibroblast culture. Although the x-ray findings of this patient are consistent with both Types I and III, recessive inheritance and glycosaminoglycan anomalies point to Type I brachyolmia.
