Oxidative stress and its association with other markers in children with CHD was established. To the best of our knowledge, this is the first time that PCO has been used as a biomarker in CHD and it may be employed as a new diagnostic biomarker in CHD and in the assessment of its severity.

Our results indicate that it may be questionable whether single-dose vitamin K prophylaxis at birth is adequate for the prevention of LHDN and if a different timing of this prophylaxis should be made for the exclusively breast fed infants.

Homozygous FH patients have significantly higher levels of hs-CRP and circulating proinflammatory cytokines, which may explain their increased risk of atherosclerotic disease. hs-CRP is an important biomarker that may be helpful in the identification of asymptomatic CHD in FH patients.

BackgroundHepatitis A virus (HAV) is a common morbidity in society, and mortality is more common in older ages. It is important to identify the prevalence in the population, the development of primary protection methods, and vaccination policies. This study aimed to identify anti-HAV seropositivity in children in 3 different schools in Diyarbakır, Turkey, to evaluate the risk factors influencing prevalence, and thus to develop strategies to prevent infection.Material/MethodsThe study was a prospective investigation of 600 children with a mean age of 10.5 years (range, 7–14), including 291 males and 309 females.ResultsThe seropositivity was 45.7% (41.2% in males and 49.8% females) with a statistically significant difference by sex (p=0.042). It was also significantly correlated with age. Factors significantly associated with seropositivity were educational level and income of parents, number of rooms in the house, type of toilet, number of siblings, and source of drinking water. Hence, older age, more siblings, crowded household, and low socioeconomic level are risk factors for seropositivity.ConclusionsProtection strategies for the disease include improving socioeconomic level, increasing the level of education, disseminating appropriate drinking water, improving infrastructure and sewage disposal, and public health education on hygiene and the importance of vaccination. We also believe that active immunization against HAV in Turkey in general and in our province in particular can prevent infection in children and related complications in older people.

Background: Hypoparathyroidism is well known to occur in thalassemia major patients, but it is thought to be uncommon and its incidence is considered to be decreasing with improvements in chelation therapy. The objective of this study was to assess the prevalence of parathyroid dysfunction in the fi rst decade of life of the patients with thalassemia major. Patients and Methods: Ninety children with beta-thalassemia major (55 males and 35 females) with a mean age of 7.17±3.78 years (1-13 years) and age and sex matched control group of 60 healthy children (36 males and 24 females) with a mean age 6.98±3.66 years (1-13) years. Serum parathyroid hormone (PTH), serum total Calcium (Ca), serum phosphorus (P), serum alkaline phosphatase (ALP), serum 25-hydroxyvitamin D (25-OHD) and serum ferritin levels were measured. Result: PTH levels were higher than normal range in 23 (25.6%) patients with a mean value of 75.2±31.3 μg/ mL compared to those having normal range level (35.3±15.2 μg/mL). Ca levels were found low in 11 patients (12.2%), and P levels were found high in 2 (2.22%) and low in 4 (4.44%) patients while high ALP levels were found in 6 (6.67%) patients. 25-OHD levels were low in all patients with a mean value of 24.95±5.82. Conclusion: Reports in the literature indicate that parathyroid dysfunction due to iron overload generally occurs in 2nd or 3rd decade of patients with thalassemia major. However, our study shows that PTH due to iron overload may develop in a signifi cant number of thalassemia major patients, therefore, all thalassemics should be carefully watched for endocrine organ function such as hyperparathyroidism might occur even in the fi rst decade of the patients with thalassemia major.
