  Aim: The aim of the present study was to determine the relative frequency of recurrent pneumonia in children and to describe its underlying illnesses.
Materials and methods: Children between 3 months and 16 years old who had a history of 2 or more episodes of pneumonia per year, or 3 or more episodes in a lifetime were investigated retrospectively at Doctor Sami Ulus Children`s Training and Research Hospital between January 2002 and December 2004.
Results: Out of 595 children admitted for pneumonia, 62 (10.42%) met the criteria for recurrent pneumonia. An underlying illness was demonstrated in 56 patients (90.32%). In this study, the underlying illness was diagnosed during recurrence in all patients. The patients with persistent pneumonia were excluded from the study. Underlying diseases were bronchial asthma (30.64%), immune deficiency disorders (17.75%), aspiration syndromes (17.75%), and congenital anomalies (16.12%). No predisposing illness could be demonstrated in 6 patients (9.68%).
Conclusion: Approximately 1 in 10 children with pneumonia in our hospital had recurrent pneumonia. Most of these children had an underlying illness, which was demonstrated. Bronchial asthma was the most common underlying illnesses for undiagnosed recurrent pneumonia in children.

  Aim: To evaluate the total homocysteine (tHcy) level, a risk factor for atherosclerosis, atherothrombosis, and insulin resistance, for sex and pubertal state differences in obese children. Its relationship with metabolic and anthropometric parameters was also investigated. Materials and methods: The study involved obese children with a body mass index (BMI) above the 95th percentile who presented with the complaint of excessive weight gain, and healthy children with a BMI below the 85th percentile. Results: The study included 100 obese (mean age: 10.2 ± 2.7 years) and 71 healthy nonobese (mean age: 10.9 ± 2.6) children. A comparison of the data from the obese group and the control group revealed that the differences in BMI, BMI standard deviation score, tHcy, total cholesterol, triglyceride (TG), insulin, high-density lipoprotein (HDL), low-density lipoprotein (LDL), and homeostasis model assessment-insulin resistance (HOMA-IR) levels were statistically significant (P < 0.05). In the obese group, the tHcy level was statistically significantly correlated with age and BMI, TG, and HDL levels (P < 0.05), while it was not statistically significantly correlated with total cholesterol, LDL, fasting glucose, insulin, or HOMA-IR levels (P > 0.05). Conclusion: The results of this study showed that the tHcy level was higher in obese children than in healthy children. However, the tHcy level was not significantly correlated with insulin resistance in obese children. Obese children should be routinely screened for high tHcy levels due to the potential atherosclerosis risks, and patients with high tHcy levels should be treated.
