Gross hematuria is uncommon in the neonatal period, with an estimated incidence of 0.21 per 1000 admissions in infants younger than one month. Although renal vein thrombosis is the most common cause, various etiologies, including congenital anomalies, must be considered. Anterior urethral valve (AUV) is a rare congenital anomaly that can cause severe obstruction and significantly impact the proximal urinary system [1].

Anatomically, AUV can cause obstruction of varying severity depending on the size and configuration of the valve [2]. The pathophysiology of AUV involves abnormal development of the urethral folds in the anterior urethra, typically at the penoscrotal junction, bulbar urethra, or penile urethra. These valves form cusp-like structures that allow antegrade flow of urine but obstruct during voiding, leading to progressive dilatation of the proximal urethra and upstream urinary tract [3].

Recent data from a matched cohort study at a high-risk pediatric center found that AUV patients demonstrate significantly lower creatinine levels at initial presentation and potentially better renal outcomes compared to posterior urethral valve (PUV) patients [4]. Prenatal diagnosis of anterior urethral anomalies is feasible as early as the second trimester, with characteristic findings including anterior urethral dilation and a keyhole sign on prenatal ultrasound [5]. Unlike PUV, which are more commonly reported, AUV presenting with gross hematuria in the neonatal period is exceptionally rare, making this case particularly noteworthy for clinicians.

Acute otitis externa (AOE) is typically a bacterial infection of the external auditory canal, which is most commonly caused by Pseudomonas aeruginosa. Although AOE occurs in all age groups, it is rarely observed in children under 2 years of age [1]. Ear drainage in a neonate is a relatively uncommon finding in the neonatal intensive care unit (NICU) population. This diagnosis requires confirmation by otoscopy [2,3].

Osteomyelitis of the temporal bone, also referred to as necrotizing otitis externa, is a severe form of infection that may develop typically in diabetic or immunocompromised patients, including premature infants. Similar to simple AOE, Pseudomonas aeruginosa is the most common pathogen [4,5]. In the NICU setting it mostly causes infection in immunocompromised hosts such as premature infants [3].

Background: neonatal cardiac surgery has evolved over the last 50 years with a large percentage of the patients achieving complete physiological repair in the neonatal period. The remaining patients achieve staged palliation with an increasing amount of success. 

Objectives: To report our experience with 1000 neonatal cardiac surgical procedures performed in the last 10 years.

Methods: We conducted a retrospective analysis of surgical outcome in all neonatal patients who underwent cardiac surgery between January 2007 and July 2016 at Schneider Children's Medical Center of Israel.

Results: A total of 1003 neonates aged < 30 days underwent surgery for congenital heart defects at our center. Neonatal surgery accounted for 22.5% of all cardiac surgeries. Neonatal operative mortality was 7.3%, Operative mortality for individual lesions were: simple aortic coarctation (CoA) (198 patients, 2.5%), CoA with hypoplastic arch (24, 4%), CoA with ventricular septal defect (VSD) (84, 2.3%), transposition of the great arteries (TGA, simple and complex, 185, 6.3%), TGA with VSD (37, 0%), truncus arteriosus (26, 3.8%), interrupted aortic arch (25, 4%), Norwood Sano (71, 19.7%), neonatal tetralogy of Fallot (41, 0%), and shunt (131 patients, 12%).

Conclusions: Neonatal surgical capabilities have improved substantially over the last decades. Excellent results can be expected for lesions that can be repaired to create biventricular circulation. Improved results can be attributed in part to the evolution of surgical strategies and assistive technologies, but essential is the collaborative effort of surgeons, cardiologists, anesthesiologists, and intensive care specialists acting as a cohesive team whose performance far exceeds the sum of its individual members’ contributions. 

 

Background: Despite progress in medical and surgical care the mortality rate of congenital diaphragmatic hernia remains high. Assessment of short-term outcome is important for comparison between different medical centers.

Objectives: To evaluate the short-term outcome of infants born with symptomatic CDH[1] and to correlate demographic and clinical parameters with short-term outcome.

Methods: We performed a retrospective cohort study in which demographic, obstetric and perinatal characteristics were extracted from infants' files. For comparison of categorical variables chi-square test and Fisher's exact test were used and for continuous variables with categorical variables the Mann-Whitney test was used. Sensitivity and specificity were estimated by receiver operator curve.

Results: The study group comprised 54 infants with CDH, of whom 20 (37%) survived the neonatal period. Demographic characteristics were not associated with survival. Regarding antenatal characteristics, absence of polyhydramnion and postnatal diagnosis were correlated with better survival. Apgar scores (above 5 at 1 minute and 7 at 5 minutes), first arterial pH after delivery (above 7.135) and presence of pulmonary hypertension were significantly correlated with survival. Also, infants surviving up to 6 days were 10.71 times more likely to survive the neonatal period.

Conclusions: The survival rate of symptomatic newborns with CDH at our center was 37% for the period 1988–2006. Prenatal diagnosis, Apgar score at 5 minutes and first pH after delivery were found to be the most significant predictors of survival. Prospective work is needed to evaluate the long-term outcome of infants with CDH.

Background: In southern Israel, a discrepancy between a relatively high prevalence of Group B streptococcus maternal carriage (12.3%) and a very low incidence of neonatal disease (0.1/1,000 live births) has been found despite the fact that no preventive strategy has been implemented.

Objectives: To determine the risk factors for maternal carriage in order to clarify this discrepancy and further examine the different aspects of GBS[1] in southern Israel.

Methods: Cultures for GBS were obtained from 681 healthy pregnant women and relevant demographic and obstetric data were collected. The medical records of 86 neonates born to carrier women were retrospectively examined. Statistical analysis was performed using the Pearson chi-square test.

Results: Women who were not born in Israel, particularly immigrants from the former USSR, were significantly prone to carry the pathogen compared to native Israeli women (Bedouin Arabs and Jews) (P = 0.03).

Conclusions: A high GBS transmission rate is expected among immigrants who came from areas with a high prevalence of maternal carriage to one with a low incidence of neonatal disease environment and were not subject to any preventive strategy. Clinical attention should be directed to this issue throughout Israel.

Background: Narcotic abuse has steadily become more prevalent in Israel and may result in an increasing number of children exposed prenatally to narcotics, with a consequent increase in the number of infants born with neonatal abstinence syndrome.

Objective: To report our experience with infants born to narcotic-addicted women between the years 1995 and 1998 at the Soroka University Medical Center.

Methods: The medical records of 24 newborns and their drug-addicted mothers admitted to our Medical Center for parturition were analyzed retrospectively. A diagnosis of NAS was established on the basis of the clinical presentation and anamnesis. The Finnegan Neonatal Abstinence Scoring System was used to assess drug withdrawal. Urine toxicological analysis for narcotics was done only for year 1998.

Results: Of the 24 newborn infants exposed prenatally to narcotics 23 (96%) developed NAS, and 78% (18 of the 23) had a Finnegan score of 8 or more. These 18 infants were treated pharmacologically (tincture of opium and/or Phenobarbital) until the score was reduced to less than 8, after which they received supportive treatment. In one child who became lethargic after the first dose of tincture of opium, the medication was stopped and supportive treatment alone was given. Four of the five neonates with scores of 7 and less were given supportive treatment. One of five infants who had a low Finnegan score at birth nevertheless received pharmacological therapy to prevent further deterioration of his physical state since he was born with severe dyspnea. Ten of the 24 children (42%) were followed for lengths of time ranging from 6 to 22 months after discharge, all of whom showed normal development.

Conclusion: About three-quarters of newborns exhibiting withdrawal syndrome required pharmacological therapy. Previous information on maternal drug abuse is a crucial criterion for early detection and treatment.
