[Hemolytic-uraemic syndrome. A review of 58 cases]. / Síndrome hemolítico-urémico. Revisión de 58 casos.

OBJECTIVES: Our objectives were to determine epidemiology, clinical and laboratory characteristics of patients with haemolytic-uraemic syndrome (HUS) treated in our centre, to describe renal and extra-renal complications and the treatment required and to relate our findings with the existing bibliography. METHODS: We performed a 33-year retrospective review. We included all patients diagnosed with HUS and monitored in our hospital from January 1974 to August 2007. Clinical histories and imaging studies were reviewed. RESULTS: A total of 58 patients were included in our study, with a mean age of 2 years 11 months and most of them were admitted to hospital in summer. Familial hypocomplementaemia was present in one case. A total of 48 patients presented with typical HUS (with diarrhoea D+ HUS). Salmonella enteritidis and Escherichia coli O157:H7 were isolated from those patients. While 7 cases presented with atypical HUS (without diarrhoea, D- HUS), most of them associated with a respiratory tract infection due to Streptococcus. In one case platelet count was normal. Kidney biopsy was performed in 18 patients and 25 cases underwent peritoneal dialysis. As regards complications, one child with D+ HUS experienced renal cortical necrosis and required kidney transplant, while in the D-HUS group, the patient with familial hypocomplementaemia had severe hypertension. CONCLUSIONS: a) Incidence of HUS in our environment is low. b) HUS can be present even with a normal platelet count. c) We had one case of HUS in a patient with familial hypocomplementaemia who experienced severe hypertension. d) In our group of patients, the course of the disease was not influenced by the white blood cell counts, decreased diuresis or hypocomplementaemia.

Síndrome hemolítico-urémico. Revisión de 58 casos / Hemolytic-uraemic syndrome. A review of 58 cases

Objetivos: Nuestros objetivos han sido determinar aspectos epidemiológicos, formas clínicas y analíticas de los pacientes con síndrome hemolítico-urémico (SHU) tratados en nuestros centros, así como describir las complicaciones renales y extrarrenales, el tipo de tratamiento requerido y relacionar nuestros casos con la bibliografía actual. Métodos: Efectuamos una revisión retrospectiva de la historia clínica, analítica y estudios de diagnóstico por imagen de los pacientes con diagnóstico de SHU, atendidos desde enero de 1974 hasta agosto de 2007, es decir, durante los últimos 33 años. Resultados: Un total de 58 pacientes fueron incluidos en nuestro estudio, con una edad media de 2 años y 11 meses; de ellos, estaban ingresados en verano 34 niños. Destaca la presencia de hipocomplementemia familiar en un caso. Con SHU típico (diarrea positivo [D+]) aparecieron 48 casos en los que se aislaron Salmonella enteritidis y Escherichia coli 0157:H7. Con SHU atípico (diarrea negativo [D-]) se contabilizaron 7 casos, y entre las causas destacaban procesos respiratorios de etiología estreptocócica. El recuento plaquetario fue normal en un caso. De los procedimientos empleados cabe destacar que se realizó biopsia renal en 18 pacientes y diálisis peritoneal en 25 casos. Entre las complicaciones se encontraron: en el grupo D+, un caso de necrosis cortical que requirió trasplante renal y en el grupo D-, un paciente con SHU familiar, hipocomplementemia e hipertensión arterial maligna. Conclusiones: Hemos llegado a las siguientes conclusiones: a) la enfermedad presenta una baja incidencia en nuestro medio; b) se ha detectado un caso con plaquetas normales; c) un paciente presentó SHU familiar recurrente con hipocomplementemia e hipertensión arterial grave, y d) indicadores como la leucocitosis, la oligoanuria o la hipocomplementemia no influyeron en el curso de la enfermedad (AU)

[Alcoholic embryofetopathy. Neonatal case reports for the past twelve years]. / Embriofetopatía alcohólica. Casuística neonatal propia en los últimos doce años.

OBJECTIVE: Alcohol embryopathy represents an important pediatric and obstetric problem, not only for the high risk of adverse effects on the neurodevelopment of the fetus and child, but for the imperative need for detecting and preventing alcohol consumption during pregnancy. In this study the clinical manifestations of newborns with maternal antecedents of alcohol consumption are reviewed. PATIENTS AND METHODS: Our experience from 1985 to 1996 with all newborns diagnosed as "children of an alcoholic mother, without associated clinical findings or partial forms (fetal alcohol effect) or as "alcohol embryofetopathy (complete forms) is reviewed. In this study we have reviewed the obstetric and neonatal records of 33 newborns born to 33 alcohol abusers, collecting both maternal (serological tests, alcohol and other substances consumed during pregnancy) and neonatal (gestational age, birth weight, birth length, head circumference, pathology, physical anomalies, cardiovascular defects and acute withdrawal symptoms) data. RESULTS: Our findings are similar to those described in other reports as regards to the incidence (1.9/1,000 newborns) and clinical manifestations, with the exception only in the low proportion of microcephalia. In our experience, alcohol consumption in pregnancy is associated with a high risk of low birth weight (39%) and intrauterine growth retardation (21%), malformations (42%, 9% cardiopathies), prematurity (54%) and maternal drug addiction (24%, with HIV serology positive in 18%). Acute withdrawal symptoms were detected in 24% of these newborns.
