Liver abscess as a atypical presentation of hepatocellular carcinoma.

We present the case of a 64-year-old male with a history of chronic liver disease due to hepatitis C virus, with a sustained viral response after oral antiviral treatment and without follow-up for 5 years. He was admitted after a one-month history of constitutional symptoms, low-grade fever, abdominal pain and a palpable epigastric tumor. Analysis showed marked elevation of acute phase reactants (48,000 leukocytes and C-reactive protein of 19mg/dl) and dissociated cholestasis. Two lesions were identified by abdominal CT.

Hipofosforemia precoz en recién nacidos de riesgo. Frecuencia y magnitud / Early hypophosphataemia in at risk newborns. Frequency and magnitude

OBJETIVO: Conocer la frecuencia y la magnitud de la hipofosforemia neonatal (< 4 mg/dl) en una UCIN y definir los grupos de riesgo. PACIENTES Y MÉTODOS: Estudio retrospectivo en neonatos hospitalizados, en periodo de 44 meses (fase 1). Estudio retrospectivo en < 1.500 g/< 32 semanas de gestación en período posterior de 6 meses (fase 2). Estudio prospectivo en < 1.500 g o CIR con peso 1.500-2.000 g. Determinaciones en días 1, 3, 7 y 14 de vida (fase 3). RESULTADOS: Fase 1: 34 de 1.394 pacientes (2,4%) fueron diagnosticados de hipofosforemia, 76% de ellos ≤ 32 semanas de gestación y < 1.500 g, y 24% > 32 semanas con peso < P10. Fase 2: 12 de 73 pacientes (16,4%) fueron diagnosticados de hipofosforemia, 5 (6,8%) con hipofosofremia< 2mg/dl. De ellos 8 fueron CIR y 4 < 1.000 g. Cinco pacientes asociaron hipopotasemia y 3 hipercalcemia. Fase 3: 9 de 20 pacientes (45%) presentaron hipofosforemia, todos < 1.000 g o con peso al nacer < 1.200 g y percentil < 10. El 33% de las muestras de los días 1, 3 y 7 mostraron hipofosforemia, < 2 mg/dl en 4 muestras. Asociaron hipopotasemia leve 5 casos (55%) e hipercalcemia leve 2 (22%). La hipofosforemia se asoció a menor nutrición enteral y más aporte parenteral de aminoácidos en los primeros días. CONCLUSIONES: La hipofosforemia es frecuente y puede ser crítica en la primera semana en prematuros < 1.000 g y en los nacidos con desnutrición fetal y peso < 1.200 g que reciben aminoácidos en la nutrición parenteral precoz

OBJECTIVE: To determine the frequency and magnitude of neonatal hypophosphataemia (< 4 mg/dL) in a neonatal Intensive Care Unit and to describe risk groups. PATIENTS AND METHODS: Retrospective study of hospitalised newborns over a 44 month period (phase 1). Retrospective study of < 1,500g /< 32 weeks of gestation newborns over a 6 month period (phase 2). Prospective study of < 1,500 g or 1,550-2,000 g, and intrauterine growth restriction (IUGR) newborns. Measurements were made on the 1st, 3rd, 7th, and 14th days of life (phase 3). RESULTS: Phase 1: 34 (2.4%) of 1,394 patients had a diagnosis of hypophosphataemia, 76% of them ≤ 32 weeks of gestation and < 1500 grams, and 24% > 32 weeks with weight < P10. Phase 2: 12 (16.4%) of 73 patients had a diagnosis of hypophosphataemia, with < 2 mg/dL in 5 (6.8%). Eight (75%) of those with hypophosphataemia had IUGR, and 4 (25%) weighed < 1,000 g. Five cases had associated hypokalaemia, and three hypercalcaemia. Phase 3: 9 (45%) of 20 patients had hypophosphataemia, all of them < 1,000 g or < 1,200 g and weight percentile < 10. Thirty-three percent of samples on days 1, 3, and 7 showed hypophosphataemia, four of them < 2mg/dL. There was mild hypokalaemia in 5 (55%), and mild hypercalcaemia in 2 (22%) cases. Hypophosphataemia was associated with lower enteral nutrition and higher parenteral amino acid intake in the early days of life. CONCLUSIONS: Hypophosphataemia is common, and can be severe, in the first week of life in premature infants < 1,000 grams, and newborns < 1,200 g with foetal malnutrition and receiving amino acids in early parenteral nutrition
