Background: This study aimed to investigate the effectiveness of intranasal dexmedetomidine in reducing pain scores during retinopathy of prematurity (ROP) screening examinations in preterm infants.

Methods: Infants born at ≤32 weeks of gestational age, undergoing routine ROP examinations in the neonatal intensive care unit, were included in the study and divided into two groups: the standard protocol group ( = 43) and the dexmedetomidine group ( = 56), over a 1-year period. Both groups received standard procedural preparation including swaddling, oral dextrose, and topical anesthesia with proparacaine.

Objective: To describe surgical procedures, previous failed pregnancies, methods for overcoming pregnancy failure and, most importantly, birth of a healthy infant, in a uterus transplantation from a deceased donor.

Background: Majority of uterus transplants have involved live donors, but several advantages make deceased donor transplantation a practicable option, principally by eliminating surgical risks to the live donor.

Methods: Uterus transplantation from a deceased donor was performed in September 2011 in Turkey.

Background: The Neonatal Therapeutic Intervention Scoring System (NTISS) is a therapy-based severity-of-illness index, The aim of the present study was to evaluate whether: (i) NTISS can predict the severity of illness with the same accuracy both in very low-birthweight (VLBW) and extremely low-birthweight (ELBW) infants, using all parameters; and (ii) the performance of NTISS can be increased by using only the significant variables.

Methods: All inborns <1500 g, and all outborns <1500 g transferred in the first 12 h of postnatal life, were included. NTISS using 63 variables was assessed for all infants at the 24th hour.

In this study, it was aimed to determine the ratio of CMV seroconversion in pregnant women, the prevalence of maternal CMV infection and also the incidence of congenital CMV infection in their newborns in the Antalya region of Turkey. During a one-year period, CMV-specific IgG and IgM were determined in all (n: 1027) pregnant women admitted at 8 to 20 weeks of gestation, an according to the presence or absence of anti CMV-IgM and CMV-IgG, pregnant women were classified as seropositive, seronegative and having maternal CMV infection. Differentiation of primary and recurrent CMV infection in women with both CMV-IgM (+) and CMV-IgG (+) antibody was determined by the avidity index (AI) of anti-CMV IgG.

Background: Intraventricular hemorrhage and posthemorrhagic hydrocephalus are common causes of neonatal morbidity and mortality among preterm and low-birth weight infants (PT-LBWIs). Clinical management of posthemorrhagic hydrocephalus (PHH) is difficult and not well standardized. In this study, we aimed to determine the incidence of hydrocephalus after intraventricular hemorrhage (IVH) and the associated risk factors for ventriculoperitoneal (V-P) shunting in PT-LBWIs.
