Intestinal Perforation during the Stabilization Period in a Preterm Infant with Congenital Diaphragmatic Hernia.

Background Delayed surgery after stabilization of infants with congenital diaphragmatic hernia (CDH) is an accepted strategy. However, the evidence favoring delayed versus immediate surgical repair is limited. We present an extremely rare case of a very low-birth-weight infant with prenatally diagnosed left-sided CDH and unexpected transmural bowel perforations developing within the postnatal stabilization period. Case Report A neonate born at 31st week of gestation with a birth weight of 1,470 g with antenatally diagnosed left-sided CDH presented with bowel dilation leading to transmural bowel perforations on the 2nd day of life. Meconium pleuroperitonitis resulted in severe systemic inflammatory response syndrome, pulmonary hypertension, multiple organ failure, and death. Conclusion In neonates with CDH deteriorating under standard postnatal management, intestinal perforation, and early surgical intervention should be considered.

Antenatal assessment of liver position, rather than lung-to-head ratio (LHR) or observed/expected LHR, is predictive of outcome in fetuses with isolated left-sided congenital diaphragmatic hernia.

OBJECTIVES: Respiratory morbidity in congenital diaphragmatic hernia (CDH) is associated with high mortality and adverse outcome. Accurate prenatal diagnosis is essential for prognosis and potential treatment in utero. The aim was to evaluate the prenatal ultrasound findings in assessing the respiratory prognosis in fetuses with isolated left-sided CDH. METHODS: We retrospectively analyzed the medical records of 59 prenatally diagnosed left-sided CDH cases managed at a tertiary perinatal center. RESULTS: Survival rate in the study group was 73% (43/59). We found no statistically significant relationship between survival and the presence of polyhydramnios, gestational age at diagnosis, lung-to-head ratio (LHR) and observed/expected LHR (O/E LHR) values, gestational age at birth and birth weight. Intrathoracic liver herniation was a statistically significant parameter adversely affecting survival (37.2% in survivors, 68.8% in non-survivors, p = 0.031) and logistic regression confirmed this relationship. The presence of pneumothorax and severe pulmonary hypertension were significantly associated with mortality (82% non-survivors versus 15% in survivors, p = 0.0001). CONCLUSION: Intrathoracic liver herniation seems to be a reliable parameter in the prediction of survival and neonatal respiratory morbidity in fetuses with isolated left-sided CDH. In contrast, we found no significant correlation between perinatal outcome and LHR, O/E LHR values, birth weight and gestational age.

Fanconi anemia with biallelic FANCD1/BRCA2 mutations - Case report of a family with three affected children.

Fanconi anemia, complementation group D1 with bi-allelic FANCD1 (BRCA2) mutations, is a very rare genetic disorder characterized by early onset of childhood malignancies, including acute leukemia, brain cancer and nephroblastoma. Here, we present a case report of a family with 3 affected children in terms of treatment outcome, toxicity and characterization of the malignancies using comprehensive cytogenetic analysis. The first child was diagnosed with T-cell acute lymphoblastic leukemia when he was 11 months old. During chemotherapy, he suffered from repeated pancytopenia, sepsis and severe vincristine polyneuropathy, and 18 months after primary diagnosis, he succumbed to secondary acute monocytic leukemia. The second child was diagnosed with stage 2 triphasic nephroblastoma (Wilms tumor), when he was 3 years and 11 months old. During chemotherapy, he suffered from vincristine polyneuropathy. Currently, he is in complete remission, 29 months following the initial diagnosis. The third child was diagnosed with medulloblastoma with classical histology, when she was 4 years and 5 months old. After the first cycle of chemotherapy, she suffered from prolonged pancytopenia, sepsis and severe skin and mucosal toxicity. Six weeks after primary diagnosis, a first relapse in the posterior fossa was diagnosed, and at 7 and half months after primary diagnosis, a second relapse was diagnosed that led to the patient's death. Our case report underscores tumor heterogeneity, treatment toxicity and poor outcome in Fanconi anemia patients of complementation group D1.

Abnormalities in pulmonary function in infants with high-risk congenital diaphragmatic hernia.

AIMS: The aim of the study was to analyze lung growth and abnormality of infant pulmonary function tests (IPFT) in congenital diaphragmatic hernia (CDH) survivors younger than three years of age with respect to unfavorable prognostic factors. METHODS: Thirty high-risk CDH survivors at the age of 1.32±0.54 years, body weight 9.76±1.25 kg were examined using IPFT: tidal breathing analysis, baby resistance/compliance, whole baby body plethysmography and rapid thoraco-abdominal compression. Gore-Tex patch was used in 13% of patients (GORE group). Pulmonary hypertension was diagnosed and managed in 13% (iNO group). Standard protocols and appropriate reference values were used and obtained data were statistically analysed. RESULTS: High incidence of peripheral airway obstruction (70%), increased value of functional residual capacity (FRCp) 191.3±24.5 mL (126.5±36.9 % predicted; P < 0.0005), increased value of effective airway resistance (Reff) 1.71±0.93 kPa.L(-1).s (144.4±80.1 % predicted; P < 0.01) and decreased specific compliance of the respiratory system (Crs/kg) 14.1±2.3 mL.kPa.kg(-1) (i.e., 76.1±20.1 % predicted, P < 0.0005) was noted in infants with CDH in comparison with reference values. Increased value of FRCp was found in GORE group (165.7±51.9 versus 120.4±31.2, P < 0.02) and in iNO group (183.1±52.6 versus 117.8±25.7 mL; P < 0.0005). CONCLUSION: A high incidence of peripheral airway obstruction, an increased value of FRCp and decreased specific compliance of the respiratory system was noted in infants with CDH. Unfavorable prognostic factors (Gore-Tex patch, pulmonary hypertension) correlate with more severe alteration of pulmonary function in infants.

Cytogenetic and array comparative genomic hybridization analysis of a series of hepatoblastomas.

Hepatoblastoma is the most common primary hepatic tumor in children, and only a limited number of detailed karyotypic analyses have been reported to date. In the present study, cytogenetic abnormalities were identified in nine cases of hepatoblastoma from a single institution. Among characteristic chromosomal changes detected were simple numerical aberrations, structural alterations of chromosomes 1, 2, and 8, and the recurrent unbalanced rearrangements der(4)t(1;4)(q25.2;q35.1) and der(6)t(1;6)(q21;q26). Array comparative genomic hybridization was applied in four of the cases. The combined cytogenetic, molecular cytogenetic, and histopathologic analyses are presented here, together with clinical data. The results substantially confirm previous findings of aberrations involving chromosomal loci on 1q, 2 or 2q, 4q, 6q, 8 or 8q, and 20 as significant in the development and clinical course of this disease.

Total prepyloric transection of stomach and vertebral trauma: case report and review of the literature.

A rare injury of stomach associated with vertebral trauma in a 10-year-old girl, a victim of a traffic accident, is presented. Early X-ray and computerized tomography scan revealed no free abdominal air, only signs of pancreas contusion and fracture of the Th 12 and L 1 vertebral body were evident. Transection of stomach was revealed during endoscopy (an attempt to perform retrograde cholangio-pancreaticography) 20 h after the trauma. Primary suture of the rupture was performed. Sepsis and multiple organ dysfunction syndrome developed in the postoperative course. The girl subsequently underwent four laparotomies for abdominal infection, bleeding and colonic stricture. After resolution of the abdominal disorders the girl underwent surgical stabilization of spine. Currently, 2 years after trauma, she is doing well without any gastroenterologic dysfunction.
