This study is the first epidemiologic study of oral mucosal lesions in adolescents in Turkey. Angular cheilitis was the only oral mucosal lesion that had a significant correlation with anemia.

The male to female ratio was 1.6:1. Occipital and beard-moustache areas were mostly affected. Positive family history was noticed in 24.1% of the patients. The age of onset was earlier in women than in men (P = 0.04). Severe forms showed more persistent (> or = 1 year) disease duration (P = 0.00). Ophiasis was more common in severe, long duration (> or = 1 year) and early onset (< or = 18 years) disease (P = 0.00 for all parameters). Childhood alopecia areata (< or = 18 years) was also associated with long duration of the disease (P = 0.016) and positive family history (P = 0.008) when compared with adult onset (> 18 years) alopecia areata.

Exclusive breastfeeding among infants less than or equal to 6 months old and continued breastfeeding (20-23 months) are high-priority indicators of infant health. We aimed to assess breastfeeding practices, using standardized breastfeeding indicators, and to determine the causes of early discontinuation of breastfeeding (< or = 6 months) in children aged 0 to 24 months in Duzce, Turkey. In this cross-sectional study, the study group consisted of 158 children, and questionnaires were completed by face-to-face interviews with the mothers. The rate of exclusive breastfeeding (< or = 6 months) was 22.4%. The rate of continued breastfeeding (20-23 months) was 10.0%. The 2 primary causes of early discontinuation of breastfeeding were inadequate milk supply (38.1%) and baby not latching on (14.3%). Half of the individuals who recommended infant formula to mothers with infants less than or equal to 6 months old were physicians.

Background: Iron may be only one of many nutritional factors that influence thyroid hormone metabolism in iodine-deficient areas. Objective: To evaluate the effect of iron status on thyroid hormone profile in adolescents living in a mild iodine-deficient area in Turkey. Subjects: Three hundred and thirty school-aged children with mean age 14 years were examined. Methods: Free triiodothyronine, free tetraiodothyronine and thyrotropin levels were analyzed by chemiluminescent enzyme immunoassay. Hemoglobin and mean corpuscular volume were measured with a Hemocounter. Iron and total iron binding capacity concentration were determined by colorimetric photometric methods. Ferritin level was determined by immunoturbidimetry.Results: Thyroid hormone levels of the children with anemia were not significantly different compared to children without anemia. No significant correlation was found between thyroid hormones and iron status. Conclusion: The thyroid hormone profile was not significantly affected in this area. This survey showed no correlation between iron status and thyroid hormone levels.

The aim of the present study was to measure full epidermal thickness, stratum corneum thickness, rete length, dermal papilla widening and suprapapillary epidermal thickness in psoriasis patients using a light microscope and computer-supported image analysis. The data obtained were analyzed in terms of patient age, type of psoriasis, total body surface area involvement, scalp and nail involvement, duration of psoriasis, and family history of the disease. The study was conducted on 64 patients and 57 controls whose skin biopsies were examined by light microscopy. The acquired microscopic images were transferred to a computer and measurements were made using image analysis. The skin biopsies, taken from different body areas, were examined for different parameters such as epidermal, corneal and suprapapillary epidermal thickness. The most prominent increase in thickness was detected in the palmar region. Corneal thickness was more pronounced in patients with scalp involvement than in patients without scalp involvement (t = -2.651, P = 0.008). The most prominent increase in rete length was observed in the knees (median: 491 µm, t = 10.117, P = 0.000). The difference in rete length between patients with a positive and a negative family history was significant (t = -3.334, P = 0.03), being 27% greater in psoriasis patients without a family history. The differences in dermal papilla distances among patients were very small. We conclude that microscope-supported thickness measurements provide objective results.
