ABSTRACT: Group B Streptococcus (GBS) is the most frequent cause of neonatal invasive disease. Two forms of GBS are recognized: early-onset and late-onset disease. The average incidence of late-onset disease is 0.24 per 1000, a figure that has remained substantially unchanged over time. Exposure to breast milk represents a potential source of infection, especially in late-onset and/or recurrent GBS disease. As a result, both breastfeeding and the use of breast milk have been questioned. We report for the first time the case of both simultaneous and recurrent infection in newborn preterm twins, born 3 weeks apart, resulting from ingestion of GBS positive breast milk. A genetically identical strain was found in both breast milk and her newborn infants. Transmission of GBS through breast milk should be considered in late-onset GBS sepsis. An eradicating antibiotic treatment of GBS positive mothers with ampicillin plus rifampin and temporary discontinuation of breastfeeding and/or the use of heat processed breast milk may represent preventive measures, although outcomes are inconsistent, for recurrent GBS disease. Guidelines on breastfeeding and prevention of recurrent neonatal GBS disease are needed. It is unfortunate that existing scientific literature is scarce and there is no general consensus. As a consequence, we propose a best practice approach on the topic.

ABSTRACT: Recent guidelines on urinary tract infection (UTI) agree on reducing the number of invasive procedures. None of these has been validated by a long-term study. We describe our 11-years experience in the application of a diagnostic protocol that uses a reduced number of invasive procedures.
We reviewed retrospectively the records of 406 children aged between 1 and 36 months at their first UTI. All patients underwent renal ultrasound (RUS). Children with abnormal RUS and those with UTI recurrences underwent voiding cystourethrography (VCUG) and dimercaptosuccinic acid (DMSA) renal scans.
RUS after the first UTI was pathological in 7.4% children; 4.4 % had a second UTI. We performed 48 VCUG: 14 patients (29%) had vesicoureteral reflux (VUR), 12 of which showed an abnormal RUS while 2 had recurrent UTI. After DMSA renal scan renal damage appeared in only 6 of them (12.5%); all these children showed grade IV VUR.
The application of our guidelines leads to a decrease in invasive examinations without missing any useful diagnoses or compromising the child's health.

ABSTRACT: We evaluated the effect of prone and supine position on cerebral blood flow (CBF) in stable preterm infants. CBF, PO(2), and PCO(2) were measured in the two positions. Peripheral oxygenation increased and CBF decreased in prone position. We speculate that CBF autoregulation may compensate for increased peripheral oxygenation, by decreasing CBF.

ABSTRACT: Opitz trigonocephaly C syndrome (OTCS) is a rare malformation syndrome with the following features: synostosis of metopic suture, craniofacial abnormalities, severe mental retardation and a multitude of pathological findings affecting almost every organ system. OTCS is associated with a high mortality rate.
We describe the case of a Caucasian male baby who died at five months of age during surgical correction of the craniofacial anomaly.
As previously reported, OTCS may have an increased mortality rate during craniofacial surgery. Careful evaluation of surgery risk-benefit ratio is warranted in such patients.

ABSTRACT: Marshall-Smith syndrome is characterized by advanced bone age, failure to thrive, respiratory problems, dysmorphic facial features, and variable mental retardation. Less than 40 cases have been reported in the literature, mostly as single case reports or small series. We describe a female newborn who, in addition to demonstrating many of the well described features of Marshall-Smith syndrome, had septo-optic dysplasia.

ABSTRACT: There has been intense discussion on the effectiveness of continuous antibiotic prophylaxis for children with vesicoureteral reflux, and randomized, controlled trials are still needed to determine the effectiveness of long-term antibiotics for the prevention of acute pyelonephritis. In this multicenter, open-label, randomized, controlled trial, we tested the effectiveness of antibiotic prophylaxis in preventing recurrence of pyelonephritis and avoiding new scars in a sample of children who were younger than 30 months and vesicoureteral reflux.
One hundred patients with vesicoureteral reflux (grade II, III, or IV) diagnosed with cystourethrography after a first episode of acute pyelonephritis were randomly assigned to receive antibiotic prophylaxis with sulfamethoxazole/trimethoprim or not for 2 years. The main outcome of the study was the recurrence of pyelonephritis during a follow-up period of 4 years. During follow-up, the patients were evaluated through repeated cystourethrographies, renal ultrasounds, and dimercaptosuccinic acid scans.
The baseline characteristics in the 2 study groups were similar. There were no differences in the risk for having at least 1 pyelonephritis episode between the intervention and control groups. At the end of follow-up, the presence of renal scars was the same in children with and without antibiotic prophylaxis.
Continuous antibiotic prophylaxis was ineffective in reducing the rate of pyelonephritis recurrence and the incidence of renal damage in children who were younger than 30 months and had vesicoureteral reflux grades II through IV.

ABSTRACT: Nephropathic cystinosis is a severe autosomal recessive inherited metabolic disease characterized by accumulation of free cystine in lysosomes. Cystinosis can lead to renal failure and multiorgan impairment. Only five cases of cystinosis with associated Bartter syndrome are reported in the literature, and no genetic evaluation has been reported. We describe two siblings with nephropathic cystinosis presenting with features of Bartter syndrome and their genetic pattern.
