Background: A pyogenic liver abscess (PLA) represents a pus-filled cavity within the liver parenchyma caused by the invasion and multiplication of bacteria. The most common offender isolated from the PLA in children is Staphylococcus aureus. Abiotrophia defectiva is a Gram-positive pleomorphic bacterium, commonly found in the oral cavity, intestinal, and genitourinary mucosa as part of the normal microbiota. It has been proven to be an etiological factor in various infections, but rarely in cases of PLA. The case presented here is, to the best of our knowledge, the first pediatric case of PLA caused by A. defectiva. Case presentation: A 13-year-old Caucasian boy presented with a two-day history of abdominal pain, fever up to 40 °C, and polyuria. Contrast-enhanced computed tomography (CT) scan revealed a single, multiloculated liver lesion, suggestive of a liver abscess. The boy had sustained a bicycle handlebar injury to his upper abdomen 3 weeks before the symptoms appeared and had been completely asymptomatic until 2 days before admission. He was successfully treated with antibiotic therapy and open surgical drainage. A. defectiva was isolated from the abscess material. Histopathology report described the lesion as a chronic PLA. Conclusions: A. defectiva is a highly uncommon cause of liver abscess in children. In such cases, various predisposing factors should be considered, including antecedent blunt abdominal trauma. © 2020 The Author(s).

Objective: The survival rate in newborns with congenital esophageal atresia (EA) is about 85–90 %, and it raises over 95 % in the developed countries. The survival rate in developing countries is much lower and the authors describe their experience with 60 newborns. Methods: Medical records of 60 newborns (40 boys and 20 girls) with congenital EA were reviewed for the prognostic factors and mortality. Results: The birth weight, mean Apgar score (AS) value, gestational age and birth-operative treatment time had significant influence on the mortality of treated patients (p < 0.05). Thirty five percent newborns had aspirational pneumonia at the moment of hospitalization and 86.7 % of them were operated during the first 48 h. The presence of associated anomalies considerably affected the death rate of treated patients (p < 0.05). The incidence of postoperative complications was similar to those in developed countries but the total mortality was higher (28.3 %); sepsis being the main cause of mortality. The postoperative complications and sepsis significantly influenced the mortality of patients (p < 0.05). Conclusions: Total mortality in newborns with EA was high; sepsis being the most frequent cause of death. The high total mortality was also caused by prematurity, delay in diagnosis, increased incidence of the aspiration pneumonia and shortage of qualified nurses. © 2015, Dr. K C Chaudhuri Foundation.
