The Serum Levels of Asymmetric Dimethylarginine, Vascular Endothelial Growth Factor, and Insulin-Like Growth Factor-1 in Preterms with Retinopathy of Prematurity.

Objective:To determine the serum levels of asymmetric dimethylarginine (ADMA), vascular endothelial growth factor (VEGF), and insulin-like growth factor-1 (IGF-1) in preterms with retinopathy of prematurity (ROP). Materials and Methods: We included 37 preterm infants. The first blood samples were obtained within the first 5 days of life and repeated at the time of the first ophthalmologic examination for ROP. The levels of ADMA, IGF-1, and VEGF were measured in all samples. Results: ROP was detected in 12 of the subjects (32.4%). We categorized the subjects as non-ROP (Group 1; n = 25), untreated ROP (Group 2; n = 7), and treated ROP (Group 3; n = 5) according to the eye findings. There were no significant differences among the groups for serum levels of ADMA, VEGF, and IGF-1 at the first sampling. Conclusion: We did not find any differences in terms of serum ADMA, IGF-1, and VEGF levels in preterm infants with or without ROP.

Severe neonatal hyperbilirubinemia in the southeast region of Turkey

Background/aim: Severe neonatal hyperbilirubinemia is an important cause of morbidity and mortality in developing countries. The aim was to assess etiologic reasons for development of severe hyperbilirubinemia and define risk factors for exchange transfusion and acute bilirubin encephalopathy (ABE) in Sanliurfa located in the southeast region of Turkey. Materials and methods: An observational cohort study included 115 infants with ≥35 weeks of gestation admitted with diagnosis of severe hyperbilirubinemia in a period of 18 months. Potential risk factors associated with exchange transfusion and development of ABE were analyzed. Results: Among 115 infants, 67 (58.3%) received exchange transfusion and 45 (39.1%) developed ABE. Rh isoimmunization (OR: 24.6, 95% CI = 2.2­271, P = 0.009), glucose-6-phosphate dehydrogenase deficiency (G6PD) (OR: 21.1, 95% CI = 1.8­238.4, P = 0.01), early discharge (OR: 14.4, 95% CI = 4.2­48.9, P ≤ 0.001), and male sex (OR: 4.3, 95% CI = 1.3­14.1, P = 0.02) were independently associated with an increased risk for exchange transfusion. Being a refugee (OR: 6.8, 95% CI = 1.8­25.8, P = 0.005) and G6PD deficiency (OR: 9.9, 95% CI = 1.3­71.9, P = 0.02) were associated with development of ABE. Conclusion: Early discharge, Rh isoimmunization, and G6PD deficiency are significant risk factors for severe hyperbilirubinemia and exchange transfusion. Prevention of early hospital discharges, family education to increase awareness for hazardous effects of hyperbilirubinemia, and early follow-up visits after discharge would reduce the disease burden.

Menstrual Characteristics of Pubertal Girls: A Questionnaire-Based Study in Turkey.

OBJECTIVE: Clinicians should show an awareness on the menstrual characteristics of adolescent girls which may differ from adults in some aspects. To define menstrual cycle features among high school girls residing in a city center in southeastern Turkey. METHODS: A cross-sectional survey was conducted on 1256 girls attending a high school located in the city center of Elazig, Turkey. Data from 879 girls (median age, 16.2 years; range, 13.6-19.2 years) who agreed to participate in the study and had started to menstruate were evaluated. RESULTS: Mean age at menarche was 12.7±1.3 years (range, 8.2-17.3 years). The mean cycle duration was 28.7±4.4 days, and the mean menstrual flow lasted 5.9±1.3 days. Severe, moderate, and mild dysmenorrhea was reported in 29%, 43%, and 28% of the girls, respectively, and 52% used analgesics for dysmenorrhea. A total of 34% of the girls defined their menstrual cycle as irregular, and 32% reported school absenteeism due to menstruation-associated complaints (pain and/or heavy bleeding). Menstrual bleeding affected attendance to classes and other school activities, daily work, social, family, and friend relationships, as well as sports/exercise activities in 43%, 49%, 58%, 48%, 44%, and 60% of the participants, respectively. In total, 30% of the responders had a problem with menstruation, and 12% and 17% of these stated that they consulted a primary care physician or specialist, respectively. CONCLUSION: Dysmenorrhea was found to be common in adolescent Turkish girls and to affect daily life in approximately half of the girls.

West syndrome due to vitamin B12 deficiency.

Vitamin B12 is one of the essential vitamins affecting various systems of the body. Vitamin B12 deficiency in infants often produces haematological and neurological deficits including macrocyticanaemia, neurodevelopmental delay or regression, irritability, weakness, hypotonia, ataxia, apathy, tremor andseizures. In this article, we report the case of a six-month-old male patient diagnosed with West syndrome associated with vitamin B12 deficiency. Although the patient had no evidence of macrocytic anemia in complete blood count, we measured the level of vitamin B12 because the patient had hypotonicity and found it to be low. No other problem was found in the other investigations directed to the etiology of West syndrome. He was being exclusively breast-fed and vitamin B12 deficiency was related with nutritional inadequacy of his mother. Vitamin B12 deficiency should be considered in the differential diagnosis of patients presenting with different neurological findings. In addition, vitamin B12 deficiency should be considered as a rare cause in West syndrome which has a heterogeneous etiology.
