Cecal duplication cyst in an infant presenting as shock: A case report.

BACKGROUND: Although intestinal obstruction is one of the most common surgical emergencies in an infant, it is difficult to diagnose neonatal enteric duplication cysts (EDC) preoperatively owing to their rarity as a cause of intestinal obstruction. We describe a case report of a neonatal EDC presenting intestinal obstruction and shock. CASE SUMMARY: A 32-d-old male infant with a prenatal sonographic finding of bladder distension was admitted to our hospital for a severely distended abdomen, fever, and oliguria. The first diagnostic hypothesis was septic shock and intestinal obstruction. The patient's symptoms worsened; following an emergency surgical exploratory laparotomy and histopathological findings, the final diagnosis of cecal duplication cyst was confirmed. The patient's postoperative course was uneventful, and on the fifth postoperative day, oral feeding restarted. Twenty days later, the patient was discharged from the hospital. CONCLUSION: Although EDC located in the cecum is exceptional, it should be considered when evaluating suspected intestinal obstruction and shock.

Gestational alloimmune liver disease treated with exchange transfusion and intravenous immunoglobulin: A case study.

Gestational alloimmune liver disease (GALD) is a materno-fetal alloimmune disorder that targets the fetal liver and often causes neonatal liver failure. GALD most commonly presents as neonatal hemochromatosis (NH), which is a severe neonatal liver injury confirmed by extra-hepatic iron accumulation at various sites. With the discovery of the alloimmune mechanism of GALD, exchange transfusion and intravenous immunoglobulin (IVIG) administration are being used as novel treatments. Here, we present a rare case of an 11-day-old female infant who presented with marked hyperbilirubinemia. Laboratory findings showed significantly elevated direct and indirect bilirubin, high ferritin and alpha fetoprotein levels, high transferrin saturation, and severe coagulopathy. Abdominal magnetic resonance imaging revealed markedly reduced T2 signal intensity in the liver and pancreas compared to the spleen, suggesting iron deposition. The infant was diagnosed with NH and successfully treated with exchange transfusion and four doses of IVIG.

Effect of red blood cell transfusion on short-term outcomes in very low birth weight infants.

BACKGROUND: Red blood cell (RBC) transfusion improves cardiorespiratory status of preterm infants by increasing circulating hemoglobin, improving tissue oxygenation, and reducing cardiac output. However, RBC transfusion itself has also been suggested to negatively affect short-term outcomes such as intraventricular hemorrhage (IVH), bronchopulmonary dysplasia (BPD), retinopathy of prematurity (ROP), and necrotizing enterocolitis (NEC) in premature infants. PURPOSE: This study aimed to analyze the relationship between RBC transfusion and short-term outcomes in very low birth weight (VLBW) infants (birth weight, <1,500 g). METHODS: We retrospectively reviewed the medical records of VLBW infants admitted to the Soonchunhyang University Bucheon Hospital between October 2010 and December 2017. Infants who died during hospitalization were excluded. The infants were divided into 2 groups according to RBC transfusion status. We investigated the relationship between RBC transfusion and short-term outcomes including BPD, ROP, NEC, and IVH. RESULTS: Of the 250 enrolled VLBW infants, 109 (43.6%) underwent transfusion. Univariate analysis revealed that all shortterm outcomes except early-onset sepsis and patent ductus arteriosus were associated with RBC transfusion. In multivariate analysis adjusted for gestational age, birth weight and Apgar score at 1 minute, RBC transfusion was significantly correlated with BPD (odds ratio [OR], 5.42; P<0.001) and NEC (OR, 3.40; P= 0.009). CONCLUSION: RBC transfusion is significantly associated with adverse clinical outcomes such as NEC and BPD in VLBW infants. Careful consideration of the patient's clinical condition and appropriate guidelines is required before administration of RBC transfusions.

Clinical Characteristics and Independent Factors Related to Long-Term Outcomes in Patients with Left Isomerism.

BACKGROUND AND OBJECTIVES: We studied the results of patient management for left isomerism (LI) and sought to determine factors that may influence survival and prognosis. SUBJECTS AND METHODS: We reviewed the medical records of 76 patients who were compatible with LI criteria between 1982 and 2014. RESULTS: Of the total study population, 29 patients (38.1%) had functional univentricular heart disease, 43 patients (56.5%) had cardiac anomalies suitable for biventricular hearts, and four patients (5.2%) had normal heart structure. Extracardiac anomalies were noted in 38.1% of the study population, including biliary atresia in 7.8% of all patients. Of the 25 patients who underwent Kawashima procedures, 24.0% developed pulmonary arteriovenous fistulas (PAVFs). During the median follow-up period of 11.4 years (range: 1 day to 32 years), 14 patients died. The 10-year, 20-year, and 30-year survival rates were 87%, 84%, and 76%, respectively. Preoperative dysrhythmia and uncorrected atrioventricular valve regurgitation were significantly associated with late death. There was no significant difference in the number of surgical procedures and in survival expectancy between patients in the functional single-ventricle group and in the biventricular group. However, late mortality was higher in functional single-ventricle patients after 18 years of age. CONCLUSION: Patients with LI need to be carefully followed, not only for late cardiovascular problems such as dysrhythmia, valve regurgitation, and the development of PAVFs, but also for noncardiac systemic manifestations.

Prophylactic Pulmonary Artery Reduction in a Young Female with Severe Pulmonary Hypertension from Complete Atrioventricular Septal Defect.

Management of severely dilated pulmonary artery (PA) associated with severe pulmonary hypertension from congenital heart disease remains controversial, primarily due to its rare nature and concern for perioperative unpredictable complications. Herein, we report a 25 year-old female with a severely dilated PA (up to 73 mm), who was successfully treated by a PA graft replacement by creating a Y-shaped conduit using a 28 mm hemashield tube in the main PA and a 20 mm hemashield tube in both proximal parts of the branch PA.
