Neonatal pyogenic liver abscess following omphalitis: A case report.

INTRODUCTION AND IMPORTANCE: Liver abscesses in neonates are rare. Omphalitis is a very rare cause. We report a case of a voluminous neonatal pyogenic liver abscess following omphalitis, successfully managed in our institution. CASE PRESENTATION: A 21-day-old full-term female newborn was brought to our institution for progressive febrile swelling of the right hypochondrium. The parents reported umbilical suppuration. Clinical examination confirmed the presence of a mass extending from the epigastric region to the right hypochondrium in a febrile baby with no other abnormalities. Laboratory investigations revealed an elevated C-reactive protein level (64 mg/dl) and hyperleukocytosis (20,800/mm3) with neutrophil predominance and normochromic microcytic anemia (hemoglobin 8.2 g/dl). Her first abdominal ultrasound was interpreted as a cyst of the common bile duct. Triple antibiotic therapy with cephalosporin, ampicillin and gentamycin was started, but unsuccessful. Abdominal ultrasound was repeated, revealing a hepatic abscess in segment 8, with a volume of approximately 17 ml. Percutaneous echo-guided drainage was performed and antibiotic therapy was readjusted after identification of the germ (Staphylococcus aureus) with good outcome. The baby was discharged two weeks later. At one month follow-up, the baby was completely asymptomatic. CLINICAL DISCUSSION AND CONCLUSION: As neonatal liver abscesses are unusual, they can lead to misdiagnosis. Omphalitis is a very rare cause. Treatment by percutaneous echo-guided drainage is simple and effective.

[Late presentation of anorectal atresia: a case report]. / Atrésie rectale membraneuse: présentation tardive à propos d'un cas.

Anorectal atresia and rectal stenosis are rare types of anorectal malformations, accounting for only 1-2% of cases. We here report one case of anorectal atresia. The study involved a female newborn baby delivered at term via vaginal birth, weighing 3600g, who was admitted with failure to pass meconium, abdominal bloating and fever on day 6 of life. Clinical examination showed a temperature of 39ºC, distended abdomen, normal anal location and peremeability, with prolapsed pinkish mass and no signs of necrosis. A cannula trocar stylet was inserted between the mass and rectal mucosa and stopped at about 3cm from the anal margin. Abdominal X-ray without treatment showed distended bowels and air-fluid levels, with no evidence of hollow-organ perforation. Due to suspicion of complete anorectal atresia, 16 gauge needle was inserted into the membrane and meconium was collected abundantly with considerable abdominal deflation. Surgical excision of the membrane was then performed. The postoperative course was uneventful and newborn baby was discharged at postoperative day 3. Anal dilatations were performed to treat anal stenosis. At 6-months´ follow-up, functional outcome was satisfactory. Anorectal atresia manifesting as failure to pass meconium associated with mass protruding through the anus has not yet been described in the literature. Membrane puncture confirmed the diagnosis. Membrane was resected with good outcome.
