Item The relationship between ultrasonographically measured testicular volumes and cord blood inhibin B concentrations in healthy term male neonatesErsoy, B; Ovali, GY; Canda, E; Onur, E; Ozyurt, BC; Tansug, NSerum inhibin B (INHB) concentrations are associated with testicular volumes (TV) in all periods of childhood. The aim of the study was to investigate the relationship between TV measured by ultrasonography (US) and cord blood inhibin B and total testosterone (TT) concentrations, stratified by mode of delivery. In total 90 male infants were included. Testes of healthy, term newborns were evaluated by US on the third day after delivery. TV were calculated using two formulae: The ellipsoid formula [length (mm) x width (mm2) x & pi;/6] and Lambert formula [length (mm) x width (mm) x height (mm) x 0.71]. Cord blood was taken for the determination of total testosterone (TT) and INHB. TT and INHB concentrations were evaluated according to TV percentiles (<10th, 10th-90th, >90th). There was a strong positive correlation between mean TV calculated with both formulae by percentile group (r = 0.777, r = 0.804, r = 0.846; p < 0.001). Cord blood INHB, but not TT were significantly lower in newborns with TV < 10th percentile compared to those with TV between 10 and 90th percentile and > 90th percentile (p < 0.05). There was a positive correlation between left and right TV calculated by either formula, and cord blood INHB (r = 0.212, 0.313, 0.320, 0.246, p < 0.05), not TT. There was no significant difference between hormones and TV when grouped by mode of delivery (p > 0.05). The Lambert and ellipsoid formulas are equally reliable in calculating neonatal testicular by ultrasound. INHB concentration is high in cord blood and positively correlated with neonatal TV. Cord blood INHB concentration may be an indicator for early detection of testicular structure and function disorders in neonates.Item Vein of Galen aneurysm that was diagnosed prenatally and supracardiac obstructed total anomalous pulmonary venous return with pulmonary hypertension: case reportTanriverdi, S; Baytur, Y; Tansug, N; Çetin, M; Coskun, SThe vein of Galen aneurysm is the most common form of symptomatic cerebrovascular malformation in neonates and infants. This anomaly may be diagnosed prenatally by several imaging modalities and causes high cardiac output, which may lead to cardiac failure, in newborns. Total anomalous pulmonary venous return is a rare entity that makes up approximately 0.4%-2% of all congenital heart diseases. The most common type of total anomalous pulmonary venous return is the supracardiac type. The pulmonary veins drain to a confluence posterior to the heart and then to a vertical vein, most commonly on the left, which enters the innominate vein and the drains to the right atrium. Obstructed pulmonary veins with supracardiac- type total anomalous pulmonary venous return can cause severe cardiac and respiratory failure. In this article, a case of a neonate with a vein of Galen aneurysm diagnosed prenatally by magnetic resonance imaging, and a supracardiac obstructed type of total anomalous pulmonary venous return with pulmonary hypertension is presented.Item Evaluation of the location of the anus by a modified technique in the neonateGenç, A; Taneli, C; Tansug, N; Kasirga, E; Yilmaz, D; Küçükoglu, T; Onag, APurpose: The aim of the current study was to bring to notice the anterior displacement of the anus and to recommend the measurement of anal position index in the neonate by a modified method. Methods: Sixty newborns (34 girls and 26 boys) were taken into study, and the anal position index (API), which is the ratio of anus-fourchette (scrotum) distance to coccyx fourchette (scrotum) distance, was measured. To obtain the measurement, a transparent adhesive tape was placed along the midline on the long axis, covering the anus. The upper and lower tips and the center of the anal circle was marked and measured using a caliber. Results: API was found as 0.46 (SD +/- 0.08) and 0.53 (SD +/- 0.05) in female and male neonates, respectively. Because an index of 0.34 in girls and 0.46 in boys are considered abnormal, the 3 female babies in the study group with API indices of 0.18, 0.28, and 0.33 were subjected to further examination. The abnormality was seen not to be rare in the Aegean region. Conclusions: An abnormal index alone cannot be the sole cause of constipation mentioned in the literature and therefore not an indication for operation, Anal position index in the neonates could be measured more accurately by the current modified method. If an anterior location of the anus is found early in infancy the baby should undergo follow-up accordingly. J Pediatr Surg 37:80-82. Copyright, (C) 2002 by W B.

As to our knowledge, it was not diagnosed in a premature newborn before. A female case of 1164 grams who was born prematurely at 29th week of gestation by cesarean section was referred to our newborn intensive care unit due to prematurity and respiratory distress with no prenatal pathological findings. Physical examination revealed tachypnea and hepatosplenomegaly. Routine laboratory measurements of the case showed significant leukocytosis (85.000/mm(3)) and anemia (Hb: 9.6 gr/dL and Hct: 27.6%). Thrombocyte count was normal. Peripheral blood smear suggested leukoerythroblastosis with the presence of nucleated erythrocyte, monocytosis, and 4% blasts. Bone marrow cytogenetic examination was normal. Parvovirus B19 Ig G and M serology were detected to be positive. The etiological factors observed in leukoerythroblastosis occurring during neonatal and early childhood period are congenital-postnatal viral infections, juvenile myelomonocytic leukemia and osteopetrosis. As to our knowledge, no case diagnosed with leukoerythroblastosis in such an early phase is avaliable in literature. As a result, premature delivery and leukoerythroblastosis presentation was thought to develop secondary to intrauterine parvovirus B19 infection.Item Changes in quantitative ultrasound in preterm and term infants during the first year of lifeTansug, N; Yildirim, SA; Canda, E; Özalp, D; Yilmaz, Ö; Taneli, F; Ersoy, BSince most of in utero bone mass accretion occurs during the third trimester and postnatal need for bone nutrients is increased, preterm infants have an increased risk of low bone mass. Early identification of the risk is of crucial importance. Quantitative ultrasound, which is a relatively inexpensive, portable, noninvasive, and radiation-free method, gives information about bone density, cortical thickness, elasticity and microarchitecture. The aim of this study was to obtain quantitative ultrasound measurements of tibial speed of sound of preterm and term infants and to assess clinical factors associated with these measurements during the first year of life. Seventy-eight preterm and 48 term infants were enrolled in this study. Measurements were made on the 10th day of life in both groups, and were repeated on the 2nd, 6th and 12th months for preterm infants and on the 12th month for the term infants. Speed of sound on preterm infants was significantly decreased on the 2nd month but significantly increased on the 12th month (P = 0.00). Comparing speed of sound of term and preterm infants, 10th day measurements were significantly different (P = 0.00), but there was not any significant difference between the 12th month values (P = 0.26). There was not any relation between biochemical parameters and speed of sound. The technique has potential clinical value for assessment of bone status. Further studies with long term follow up are needed to evaluate the value of quantitative ultrasound with other bone markers to predict the risk of fracture. (C) 2010 Elsevier Ireland Ltd.

These cardiac functions were evaluated by Doppler echocardiography to assess adaptation differences. Cardiac output, heart rate, stroke volume, mean arterial pressure, total systemic vascular resistance, ejection fraction, and ductus arteriosus diameter were determined and compared at 1, 24 and 72 h of life in 22 infants born vaginally (group 1) and 23 born by caesarean section (group 2). One hour after delivery, heart rate, mean blood pressure, and total systemic resistance were found to be higher in group 1 infants (P < 0.01, P < 0.05, P < 0.05 respectively). Stroke-volume measurements were significantly higher in group 2 (P < 0.05). The ejection fraction and cardiac output values were similar in both groups. At 24 and 72 h, no significant differences were observed in measurements of infants born vaginally or by caesarean section. We did not find a parameter negatively affecting healthy newborns in either mode of delivery. However, under pathological conditions affecting the cardiovascular system at 1 h of life, including perinatal infections and hypoxemia, a lower stroke volume, higher heart rate, higher mean blood pressure, and higher peripheral resistance may cause additional work load to the cardiovascular system in infants born vaginally.Item Vitamin A status of healthy children in Manisa, TurkeyTansug, N; Polat, M; Çesme, S; Taneli, F; Gözmen, S; Tokusoglu, Ö; Yilmaz, D; Dinç, GBackground: Vitamin A deficiency is a major public health nutrition problem in the developing world. Even subclinical Vitamin A deficiency is associated with increased childhood mortality. Severe maternal vitamin A deficiency may cause increased mortality in the first months of life. There have been a limited number of studies regarding vitamin A status in Turkey. The aim of this study was to assess vitamin A status of healthy children in Manisa, Turkey. Methods: Vitamin A status of 100 healthy children aged 36-48 months is evaluated. The children were seen during routine examination. Serum retinol concentrations were measured by high-performance liquid chromatography. Duration of breast feeding, age solid foods introduced, use of supplementary vitamins, weight and height, and intake of specific groups of nutrients on a daily, weekly and monthly basis were collected from a questionnaire completed by the mothers. Height and weight z-scores were calculated according to national standards. Mothers of 20 of the 100 children were known to have normal serum and breast milk retinol concentrations. Children with normal serum retinol concentration were compared with the children with VAD. Student's t-test and Mann-Whitney test were used to compare independent variables. The Pearson correlation analysis test was used to test relation between numeric variables. Results: Mean retinol concentration was 0.98 +/- 0.32 mu mol/L in the whole study group. Serum retinol concentrations were normal (>0.70 mu mol/L) in 89% of the children. When children with normal serum retinol concentrations were compared with those with retinol concentrations lower than 0.70 mu mol/L, there was no difference in terms of age, gender, weight and height at the time of study, z-scores, birth weight, birth length, duration of breast feeding, time to begin solid food, rate of supplementary vitamin use, and rate of infections (P > 0.05). There was not any relation between vitamin A concentrations and weight and height at the time of study, z-scores, birth weight, birth length, duration of breast feeding, time to begin solid food, vitamin use, and frequency of intake of specific groups of nutrients (P > 0.05). Conclusions: This study showed that VAD is a moderate health problem in Manisa.Item Prediction of neurodevelopmental outcome in term neonates with hypoxic-ischemic encephalopathyPolat, M; Simsek, A; Tansug, N; Sezer, RG; Özkol, M; Baspinar, P; Tekgül, HBackground: Hypoxic ischemic encephalopathy may result in many neurological deficits. It is crucial to make early diagnosis and assess the prognosis correctly. Aims: We aimed to determine the factors to evaluate the prognosis of hypoxic ischemic encephalopathy. Methods: Electroencephalography, neuroimaging, periodic neurological exams and a developmental test at 44-48 months after discharge from the hospital were performed on twenty five term newborn infants with clinical evidence of hypoxic ischemic encephalopathy. Results: Normal/mildly abnormal neonatal electroencephalography correlated with favorable outcome, particularly if neuroimaging was normal. The cranial MRI sensitivity was 83.3%, while the specificity was 57.9%, the positive predictive value was 38.5%, and the negative predictive value was 91.6%. Moderate/severely abnormal electroencephalography and multifocaVdiffuse cortical or deep gray matter lesions correlated with poor outcome. Conclusions: Newborn infants with hypoxic ischemic encephalopathy should be treated in neonatal intensive care units, assessed with periodic neurological examination, electroencephalogram and brain imaging. This would help to initiate early intervention and improve the outcome of patients. (C) 2012 European Paediatric Neurology Society. Published by Elsevier Ltd.

Nosocomial infections in neonatal units in Turkey: epidemiology, problems, unit policies and opinions of healthcare workers. Turk J Pediatr 2010; 52: 50-57. The epidemiology of nosocomial infections in Turkish neonatal intensive care units (NICUs) shows that nosocomial sepsis is an important problem, especially for very low birth weight (VLBW) infants, and gram-negative agents, particularly Klebsiella species, are still the major causes of nosocomial infections. Sepsis frequency was 6.4%, ranging from 2.1 to 17%, in 16 centers in Turkey. Sepsis frequency was 22% in infants <1500 g, 6% in those 1500-2500 g, and 3% in those >2500 g. Sepsis-related mortality was 24.4 for 100 sepsis cases, ranging from 0 to 75 for 100 cases. Ventilator-associated pneumonia frequency was 1.7%, catheter-related infection frequency was 0.14% and urinary tract infection frequency was 3.7%. Healthcare workers (HCWs) complain of the inadequacy of some basic facilities and of staffing; however, they are aware of the causes and solutions and are willing to overcome this major health problem. We conclude that Turkish neonatal HCWs are quite optimistic about preventing neonatal nosocomial infections.Item Retinol and α-tocopherol concentrations in breast milk of Turkish lactating mothers under different socio-economic statusTokusoglu, Ö; Tansug, N; Aksit, S; Dinc, G; Kasirga, E; Özcan, CRetinol and alpha-tocopherol levels in breast milk of Turkish mothers under different socio-economic status were investigated. Mature milk samples were collected from 92 lactating mothers living in Izmir and in Manisa, cities of Turkey, who were at 60-90 days of the lactating period. Socio-economic, anthropometric, and dietary data were collected by means of a questionnaire. The body mass index was used to determine the nutritional status. The retinol and alpha-tocopherol contents of breast milk were determined by high-performance liquid chromatography; the concentration of alpha-tocopherol was 9.84 mu g/ml whereas retinol levels were 81.5 mu g/100 ml. The questionnaire survey was used to determine the level of these vitamins in the daily ration of the women. No significant differences were found in terms of milk retinol and alpha-tocopherol levels for the variables income, educational level and mothers' body mass index.
