Calcaneus osteomyelitis is a rare infection in newborns. Invasive procedures, prematurity and low birth wight are some causative factors. The clinical signs may be mild. We report a neonate with calcaneous osteomyelitis which was secondary to a Guthrie test sample. She was admitted to hospital with swelling, redness and increased temperature on her heel. Superficial tissue ultrasound showed fluid collection with heavy content was observed on the posterior of the right foot. Puncture and drainage was performed and methicillin-susceptible Staphylococcus aureus was isolated from the drainage culture...

The authors present an overview of lower urinary tract obstruction (LUTO) in the fetus with a particular focus on the insult to the developing renal system. Diagnostic criteria along with the challenges in estimating long-term prognosis are reviewed. A proposed prenatal LUTO disease severity classification to guide management decisions with fetal intervention to maintain or salvage in utero and neonatal pulmonary and renal function is also discussed. Stage I LUTO (mild form) is characterized by normal amniotic fluid index after 18 weeks, normal kidney echogenicity, no renal cortical cysts, no evidence of renal dysplasia, and favorable urinary biochemistries when sampled between 18 and 30 weeks; prenatal surveillance is recommended...

Perinatal autopsy remains the gold-standard procedure used to establish the fetal, neonatal or infant abnormalities. Progressively, perinatal pathology has become a specialized field with important roles of audit for fetal prenatal diagnostic tools, in parents counseling regarding future pregnancies, in scientific research, for epidemiology of congenital abnormalities and teaching. The differences between prenatal ultrasound and autopsy reports represent a strong argument for the autopsy examination following termination of pregnancy...

IMPORTANCE: Postnatal dexamethasone is associated with reduction in bronchopulmonary dysplasia. There remains, however, concern that its short-term benefits are accompanied by long-term adverse effects e.g. poorer neurodevelopmental outcomes. OBJECTIVE: Our aim was to determine the effects of administration of postnatal dexamethasone on respiratory and neurodevelopmental outcome at two years of age after adjusting for neonatal and infant risk factors. MATERIALS AND METHODS: The study included 412 infants born at 23-28 weeks of gestation, 29% had received postnatal dexamethasone...

AIM: To compare intra-amniotic versus fetal subcutaneous injections for selective fetal labeling in multifetal rat pregnancies. METHODS: A total of 14 pregnant rats were randomized to receive intra-amniotic injections of dyes (including Fluorescein, Indigo Carmine, or Evans Blue) or fetal subcutaneous injections (of commercial tattoo ink) both guided by ultrasound at 15-17 days of gestation. Survival, injection, and labeling success rates of both techniques were compared...

This is a report of an infant born near term with neonatal stroke and haematuria. Changes were noted on foetal magnetic resonance images, and these persisted postnatally. A routine renal ultrasound scan during follow-up detected haematuria with no associated proteinuria. A likely pathogenic genetic mutation was identified. This case highlights a relatively newly discovered cause for hereditary nephropathy affecting the basement membrane, initially affecting the glomerular but later the renal tubular basement membranes...

Supraventricular tachycardia (SVT) is the most common neonatal arrhythmia. Necrotising enterocolitis (NEC) is a disease with multifactorial aetiology, most common in preterm infants. There are three previous case reports in the literature of NEC following neonatal SVT. We present two cases of late preterm infants with NEC, characterised by pneumatosis on abdominal X-ray and ultrasound, following recurrent SVT without haemodynamic instability. The infants were successfully treated with antibiotic therapy and bowel rest...

AIM: In this study, we evaluate the associations between fetal urinary production rate (FUPR), measured by ultrasound, and adverse neonatal outcome in women with preterm premature rupture of membranes (PPROM). METHODS: We conducted a prospective pilot cohort of singleton pregnancies complicated by PPROM occurring at gestational week 24 or later managed until spontaneous labor (after 48 h of admission), chorioamnionitis, or induction by protocol at 35 + 0 weeks. FUPR was evaluated by 2D sonography at admission (corrected for gestational age)...

Mid-trimester preterm premature rupture of membranes (PPROM), defined as rupture of fetal membranes prior to 28 weeks of gestation, complicates approximately 0.4%-0.7% of all pregnancies. This condition is associated with a very high neonatal mortality rate as well as an increased risk of long- and short-term severe neonatal morbidity. The causes of the mid-trimester PPROM are multifactorial. Altered membrane morphology including marked swelling and disruption of the collagen network which is seen with PPROM can be triggered by bacterial products or/and pro-inflammatory cytokines...

OBJECTIVES: To determine whether fetuses with fetal growth restriction (FGR) are more likely to have abnormal cerebral vascular flow patterns compared to fetuses who are appropriate for gestational age (AGA) when quantified by using 3-dimensional (3D) power Doppler ultrasound. METHODS: We conducted a prospective cohort study of singleton gestations presenting for growth ultrasound examination between 24 and 36 weeks' gestation. Patients with FGR (estimated fetal weight < 10th percentile) were enrolled and matched 1:1 for gestational age (±7 days) with AGA fetuses...

Children are particularly at risk for stroke in the neonatal period. 1/3 of all strokes in children occur during the perinatal period. The incidence of perinatal stroke is 1:4000. A differentiation is made between ischemic stroke and hemorrhagic stroke. Ischemic strokes are caused by arterial occlusion due to thrombosis or embolism. As a result of the nonspecific clinical symptoms in this age group, diagnosis is usually made too late. The only relatively specific symptom is focal cerebral seizure during the first week of life...

PURPOSE: The one-step approach for screening of GDM will increase the incidence 2- to 3-fold. These larger cohorts may need to target high-morbidity subsets to be cost-effective. We asked whether ultrasound could stratify the GDM patients with the highest risk for a large for gestational age (LGA) infant. MATERIALS AND METHODS: A retrospective analysis was performed on 413 GDM patients diagnosed using the one-step approach. Ultrasound data from 28 weeks 0 day to 34 weeks 6 days was studied...

OBJECTIVE: To evaluate perinatal outcomes in case of non-primary maternal cytomegalovirus (CMV) infection. METHODS: We performed a retrospective cohort study of pregnant women with active CMV infection referred to our unit over a 15-year period (January 2000 to December 2014). Non-primary infection was diagnosed on the basis of the results of confirmatory serological and virological tests (avidity test, immunoblotting, real-time PCR-DNA). The vertical transmission rate and the percentage of symptomatic congenital infection were determined in this group of patients...

Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is the most common cause of severe neonatal thrombocytopenia and intracranial bleeding in term newborns. Intracranial hemorrhage (ICH) commonly results in death or severe, lasting neurologic disability. The timing of ICH is also important for management of the next affected pregnancy in cases of FNAIT. This manuscript reviews the advantages and disadvantages of the different radiologic methodologies to identify and characterize ICH. It discusses the limits of ultrasound and the advantages of magnetic resonance imaging allowing avoidance of the radiation associated with computed tomography (CT) scans...

Proptosis in the neonatal period is relatively infrequent and has diverse underlying etiologies. One of the more common causes appears to be orbital subperiosteal hematoma. Early detection, differentiation from other causes, and regular follow-up are essential as loss of vision can occur. We describe two cases of neonatal proptosis caused by orbital subperiosteal hematoma highlighting different diagnostic and management approaches, and provide a summary of previously reported cases. Spontaneous resolution occurs in most cases; however, emergent surgical evacuation is warranted in cases of optic nerve compression...

OBJECTIVES: Tetralogy of Fallot with absent pulmonary valve syndrome is a rare form of tetralogy of Fallot with dilatation of large pulmonary arteries. Prognosis is related to the severity of the cardiac malformation and to bronchial tree compression by dilated pulmonary arteries. This study analyses the prenatal echographic lung appearance in fetuses with tetralogy of Fallot with absent pulmonary valve and discusses its significance. METHODS: We carried out a retrospective review of fetal and postnatal files of nine fetuses diagnosed with tetralogy of Fallot with absent pulmonary valve syndrome in our institution...

BACKGROUND: The umbilical coiling index (UCI) is a measure of the number of coils in the umbilical cord in relation to its length. Hypercoiled cords with a UCI of >0.3 coils/cm have been associated with adverse fetal and neonatal outcomes. AIMS: The primary aim is to determine the accuracy of UCI measured on second trimester ultrasound in predicting UCI at birth. The secondary outcome is to investigate the association between hypercoiling of the umbilical cord on prenatal ultrasound and adverse maternal, fetal and neonatal outcomes...
