Respiratory Oscillometry in Newborn Infants: Conventional and Intra-Breath Approaches.

Background: Oscillometry has been employed widely as a non-invasive and standardized measurement of respiratory function in children and adults; however, limited information is available on infants.

Aims: To establish the within-session variability of respiratory impedance (Zrs), to characterize the degree and profile of intra-breath changes in Zrs and to assess their impact on conventional oscillometry in newborns.

Methods: 109 healthy newborns were enrolled in the study conducted in the first 5 postpartum days during natural sleep.

Unlabelled: Összefoglaló. Bevezetés: A szakirodalomban számos felmérés született az újszülöttkori bőrelváltozások előfordulási gyakoriságának vizsgálatára. Az epidemiológiai vizsgálatok eredményei azonban nem mindig adaptálhatók, hiszen jelentős különbségeket találunk az egyes népcsoportok bőrmanifesztációi között, emellett kevés és ellentmondásos adat áll rendelkezésre arról, hogy milyen tényezők befolyásolják ezen bőrtünetek kialakulását.

Unlabelled: Összefoglaló. Bevezetés: Az újszülöttkori szepszis ritka, de magas mortalitással járó állapot. Az Egészségügyi Szakmai Kollégium Neonatológiai Tagozata 2017-ben bevezette a korai szepszisről szóló állásfoglalást, meghatározva a kezelés indikációját a túlzott mértékű antibiotikumadás elkerülése céljából.

Effect of nasal airway nonlinearities on oscillometric resistance measurements in infants.

Oscillometric measurements of respiratory system resistance (R) in infants are usually made via the nasal pathways, which not only significantly contribute to overall R but also introduce marked flow (V')-dependent changes. We employed intrabreath oscillometry in casts of the upper airways constructed from head CT images of 46 infants. We examined oscillometric nasal resistance (R) in upper airway casts with no respiratory flow (R) and the effect of varying V' on R by simulating tidal breathing.

Early detection of developmental dysplasia of hip by ultrasound.

Objective: To assess the effectiveness of early universal ultrasound (US) screening of developmental dysplasia of the hip (DDH).

Study Design: A prospective study of universal hip screening of all mature neonates was conducted from 2012 to 2013, at the Department of Obstetrics and Gynaecology, University of Szeged; 1636 newborns (3272 hips) had clinical examinations and hip ultrasound by the Graf method within the1st 3 days of life. Prevalence of DDH, risk factors, sensitivity and specificity of clinical examinations were evaluated.

Evaluation of placental vascularization indices in monochorionic diamniotic and dichorionic diamniotic twin pregnancies.

Objectives: We aimed to investigate and compare placental vascularization indices between monochorionic-diamniotic, dichorionic-diamniotic normal twin pregnancies, and normal singular pregnancies. We hypothesized that there is correlation between placental three-dimensional power Doppler vascularization indices and birth weight in case of twin pregnancies, and that normal singular pregnancies have higher placental vascularization indices than normal twin pregnancies.

Study Design: Placental three-dimensional power Doppler vascularization indices, such as vascularization index, flow index, and vascularization-flow index were measured in monochorionic-diamniotic (N = 15) and dichorionic-diamniotic (N = 36) normal twin pregnancies, and in normal singular (N = 109) pregnancies.

Adverse perinatal outcome in teenage pregnancies: an analysis of a 5-year period in Southeastern Hungary.

Objective: To determine the risks of adverse perinatal outcomes of teenage mothers.

Material And Methods: A retrospective analysis was performed on teenage mothers (under 20 years of age) who delivered in the period of 2010-2014 at the Department of Obstetrics and Gynecology, University of Szeged (study group). All mothers who delivered in Hungary during the same period were studied as a control group.

Cutaneous lesions and disorders in healthy neonates and their relationships with maternal-neonatal factors: a cross-sectional study.

Background: Cutaneous lesions are very common in neonates. Although a number of studies have reported on their incidence, very little is known about the factors that influence them. We set out to investigate a large population of neonates with the aims of achieving an overall picture of neonatal skin manifestations, and examining their relationships with various maternal, neonatal and perinatal factors.

Predictors of caesarean section - a cross-sectional study in Hungary.

Purpose: The aim of this study was to analyse the factors associated with caesarean section (CS) at the Department of Obstetrics and Gynaecology, University of Szeged, Hungary.

Study Design: Data collection was based on self-administered questionnaire and medical records related to the deliveries in the year of 2014. Maternal age, education level, marital status, pre-gestational body mass index (BMI), infertility treatment, previous CS, gestational diabetes mellitus (GDM), pre-pregnancy hypertension and pregnancy-induced hypertension (HT/PIH) were examined.

Adrenal haemorrhage in term neonates: a retrospective study from the period 2001-2013.

Objective: To assess the incidence, risk factors and clinical presentations of neonatal adrenal haemorrhage (NAH) in uncomplicated, singleton and term deliveries.

Methods: A retrospective analysis of 26,416 term neonates delivered between 2001 and 2013, and screened with abdominal ultrasonography.

Results: Of the 26,416 neonates, 74 (0.

Assessment of respiratory mechanics with forced oscillations in healthy newborns.

Background: Lung function data in healthy newborn infants are scarce largely due to lack of suitable techniques, although data for developmental and prenatal exposure studies are much needed. We have modified the forced oscillation technique (FOT) for the measurement of respiratory mechanical impedance (Zrs) in unsedated sleeping infants in the first 3 days of life.

Methods: Zrs was measured during 30-s epochs of quiet sleep in term neonates born via spontaneous vaginal delivery with a non-invasive FOT between 8 and 48 Hz.

A cross-sectional study of newborns over a 20-year period in Szeged, Hungary.

Objective: Records of metric data of birth, serve not only the medical needs of the newborn baby, but are also indicators to assess the status of public health.

Methods: This is a retrospective study of 4946 newborns (singleton: 2508 boys and 2365 girls) born in 1989 and in 2009 at the Department of Obstetrics and Gynaecology of the University of Szeged. We aimed as to compare and map the metrical changes over 20 years, and to describe the averages of four body parameters of the normal birth weight (2500-4000 g) subgroup (3993 singleton babies) in both years.

Neonatal outcome of macrosomic infants: an analysis of a two-year period.

Objective: To assess the neonatal outcome of macrosomic neonates in uncomplicated, singleton, term deliveries.

Study Design: A retrospective analysis was performed on 5738 live-born term neonates born in the period 2008-2009. The neonatal outcomes were compared between two birth weight (BW) groups: the macrosomic neonates born with BW≥4000g and a control group: 2500-3999g.
