RESUMO
New therapies have been introduced for the prophylaxis and treatment of respiratory syncytial virus (RSV) infection in recent years. The aim of the study was to determine the epidemiological and clinical characteristics of infants hospitalized with bronchiolitis in our area. All patients under 1 year of age admitted with acute bronchiolitis during four consecutive RSV seasons from February 1, 1997 to June 30, 2000 were enrolled in the study. The records of patients admitted during the first season were reviewed retrospectively while the rest were followed prospectively. A total of 636 infants with bronchiolitis were admitted and RSV infection was documented in 61% of those tested. Admission to intensive care unit (ICU) was required for 6.2% of them and was more common in premature infants (26%) (p < 0.001). Case fatality rate was 0.7% (overall 0.3%). RSV bronchiolitis accounted for about 12% of all infant admissions during the 5 months of the yearly outbreak. Patients with documented RSV infection had a more severe illness with a higher ICU admission rate (6 vs. 1%, p = 0.008) and longer duration of hospitalization (mean 6.3 vs. 5.3 days, p < 0.001) compared to those who tested negative. Although none of the patients had a positive blood culture on admission a considerable number of them (210/636, 33%) were treated with antibiotics. RSV infection has a significant impact on infant morbidity in our settings which is more serious among those born prematurely. Documentation of RSV infection may be a marker of more severe illness in infants hospitalized with bronchiolitis. Antibiotic use has to be restricted since the occurrence of a serious bacteraemic illness on admission is a very rare event.

SETTING: A hospital referral centre for childhood tuberculosis in Athens. OBJECTIVE: To evaluate the effectiveness of the screening programme implemented for childhood tuberculosis, through its impact on the epidemiological index. DESIGN: In Greece, tuberculosis has been systematically screened for in children since 1991 using the tuberculin skin test. The epidemiological and clinical profiles of all tuberculous children who attended the TB clinic were compared. The children were divided into those who attended in 1982-1990 and those who did so in 1991-1999. RESULTS: A total of 1122 TB patients were screened. In the second period there was an increase in numbers of immigrant children (3% vs. 28%, P = 0.0001), the rate of extra-pulmonary TB decreased (16% vs. 7.6%, P = 0.0001), patients identified by the screening programme increased (19% vs. 57%, P = 0.0001) and the number of symptomatic children fell (51% vs. 16%, P = 0.0001). The proportion of children who failed to attend for regular follow-up was lower during the second period (20% vs. 7%, P = 0.0001). CONCLUSIONS: Our study suggests that the screening programme applied in Greece during the last decade has contributed to the early identification of tuberculosis, and the limitation of symptomatic patients and extrapulmonary TB cases.

The role of epidemiological and clinical features for the early differential diagnosis between Mycobacterium tuberculosis (MTB) complex and non-tuberculous mycobacterial (NTM) cervical lymphadenitis in children was examined in this study. From 1982 to 1997, 24 MTB complex cases and 26 NTM cases were diagnosed, of which 75% and 25%, respectively, presented during the first half of the study period. Epidemiological and lymph-node features and anatomical areas were not helpful in the differential diagnosis between the 2 groups. Fulfilment of 2 out of 3 criteria (positive tuberculin skin test reaction, abnormal chest radiograph, contact with a person with infectious tuberculosis) was associated with 92% sensitivity for the diagnosis of MTB lymphadenitis. 37.5% of the MTB cases and 88.5% of the NTM cases were culture-confirmed; all inconclusive cultures concerned patients with spontaneous drainage and fistula. Surgical intervention was required in 67% of the MTB cases. All NTM cases were managed by surgery alone. Fistulae or cheloids occurred in all patients in whom incision and drainage were applied instead of total excision. Excellent aesthetic results were achieved in patients who presented within 1 month following the onset of lymphadenitis. The spectrum of mycobacterial cervical lymphadenitis in children in Greece has changed during the 1990s. Early and prompt treatment contributes to the diagnosis and response.

Records were reviewed of 82 immunocompetent children (median age, 2. 5 years) from southern Greece who were diagnosed with visceral leishmaniasis from 1986 through 1998. Forty-nine (58%) patients originated from the city of Athens; of them, 46 (94%) lived by hills bordering the city. The median interval from the onset of symptoms to admission was 10 days. Fever and splenomegaly were observed in >95% of the patients. Thrombocytopenia was the most frequent hematological finding (80%). All patients were treated with meglumine antimonate; 20 (24%) of them were partially treated on an outpatient basis. Rapid clinical response was noted in all patients but one. Five patients relapsed; 3 responded to reintroduction of meglumine antimonate, 1 responded to liposomal amphotericin B, and 1 underwent splenic artery ligation. We conclude that pentavalent antimonials remain the first choice of treatment for visceral leishmaniasis in immunocompetent children in areas where resistance has not become a problem. It is possible to treat affected patients with outpatient administration of these agents, making them feasible options for therapy.

METHODS: The clinical and epidemiological features of 102 children with extra-pulmonary tuberculosis, diagnosed between 1982 and 1998 at P & A Kyriakou Children's Hospital were reviewed. RESULTS: During the past decade, a 50% increase of admissions for extra-pulmonary tuberculosis was observed. The source of infection was disclosed in 48 patients. Diagnoses included superficial lymphadenitis (n = 48), pleural effusion (n = 27), meningitis (n = 16), skeletal tuberculosis (n = 5), miliary tuberculosis (n = 3), abdominal tuberculosis (n = 2), and pericarditis (n = 1). Miliary tuberculosis developed in infants, lymphadenitis and meningitis in preschool children, and pleural effusion and skeletal tuberculosis in older children. None of the patients with extra-pulmonary tuberculosis died; however, six patients with meningitis developed permanent neurological deficits. In these patients, antituberculous treatment was introduced at a median of six days following admission as compared with one day in patients with no complications. Poverty, immigration, and limited access to medical services were common among patients with meningitis.

SETTING: A worldwide re-emergence of tuberculosis has been observed during the last decade. However, few studies of infants with tuberculosis appear in the literature. OBJECTIVE: To describe tuberculosis during infancy. DESIGN: The records of all infants diagnosed with tuberculosis at a tertiary care hospital from 1982 to 1998 were reviewed. RESULTS: Thirty-nine infants with a median age of 10 months were identified, 59% of whom presented during the second half of the study period. Diagnoses included endothoracic tuberculosis (33 patients), meningitis (3), miliary tuberculosis (2) and cervical lymphadenitis (1). Reasons for medical evaluation were the onset of symptoms (25 patients), contact investigation (12) and tuberculin skin test screening (2). Common signs and symptoms included fever (22 patients), cough (7), appetite loss (4) and wheezing/rales (4). Chest X-ray revealed hilar adenopathy (22 patients), infiltrates (16), atelectases (3) and miliary pattern (2). Cultures were attempted in nine patients and were positive in seven. All patients responded promptly to treatment. No complications or deaths occurred. CONCLUSION: Tuberculosis in infants has been diagnosed increasingly during the last decade. Endothoracic tuberculosis predominates. One third of the patients were diagnosed due to contact investigation. As early diagnosis and treatment appears to prevent complications and reduce mortality, pediatricians should be alert for tuberculosis in an infant with an atypical picture suggestive of infection.

OBJECTIVES: To describe the clinical and epidemiologic features, management and outcome associated with the development of nontuberculous mycobacterial (NTM) superficial lymphadenitis in children. METHODS: The medical records of all children 0 to 14 years of age with NTM superficial lymphadenitis who were diagnosed at P. and A. Kyriakou Children's Hospital between January, 1982, and December, 1997, were reviewed. RESULTS: Forty-seven children were identified, 76.5% during the second half of the study period. Mycobacterium avium complex was the predominant isolate. Children with NTM lymphadenitis noted satisfactory aesthetic results when total excision was performed within 1 month after its onset. CONCLUSIONS: NTM superficial lymphadenitis in children has been increasingly recognized during the last decade. Prompt total excision of the involved lymph node is required in such patients.

A boy, 4 years, 9 months of age, presented with acute hemiplegia, lethargy, ataxia, and dysarthria 24 hours prior to the eruption of typical varicella exanthem. Magnetic resonance imaging findings were typical of multiple cerebral ischemic infarcts. It is suggested that during the period of secondary viremia varicella zoster virus invaded the cerebral blood vessels causing vasculopathy and cerebrovascular infarcts.

The incidence of INH-associated liver injury was evaluated in 239 children aged between 9 and 14 years, who were receiving 300 mg INH/day for tuberculosis prophylaxis. Serum SGOT and SGPT levels were determined before INH administration and at 4-weekly intervals thereafter. Levels of both enzymes were raised during the first 3 months of treatment in 18 (7.5%) children, while in 23 (9.6%) children either SGOT or SGPT exceeded normal levels (SGOT greater than 40 units, SGPT greater than 30 units). Only 2 (0.8%) children showed SGOT and SGPT values above 100 units and in them treatment with INH had to be discontinued. In all other children transaminases returned to normal during uninterrupted INH administration. It was noted also that transaminase values in children who did not exhibit a rise above normal, still had significantly higher levels during treatment compared with before. The findings of this study suggest that liver injury in children receiving INH for prophylaxis occurs more often than it had hitherto been believed but that it is usually mild and transient.
