Síndrome de piel escaldada asociado a estafilococcemia en un neonato: reporte de un caso / Scalded skin syndrome associated with staphylococcemia in a neonate: a case report

RESUMEN El síndrome de piel escaldada estafilocócica es una patología poco frecuente que principalmente afecta a población pediátrica. Si bien en la mayoría de los casos tiene un desenlace favorable, un buen diagnóstico diferencial y manejo antibiótico oportuno son cruciales para un buen pronóstico. Objetivo: Describir un caso de síndrome de piel escaldada con aislamiento en hemocultivos de S. Aureus meticilino resistente en un neonato. Caso clínico: Femenina de 25 días de vida, nacida a término y sin antecedentes perinatales relevantes que cursa con fiebre, dermatosis eritemato-descamativa generalizada, edema palpebral y de miembros inferiores. Se hospitalizó con diagnóstico de sepsis neonatal tardía y sindrome de piel escaldada. Reporte de hemocultivos con crecimiento de S. Aureus meticilino resistente, manejada con vancomicina durante 14 días. Control de hemocultivos negativos, evolución satisfactoria y de alta hospitalaria sin complicaciones. Conclusiones: A pesar de la baja incidencia del síndrome de piel escaldada, es importante incluir dentro del diagnóstico diferencial de la fiebre y las dermatosis tardías del neonato la infecciones por toxinas del S. Aureus, ya que su identificación y tratamiento oportuno son de gran importancia en el pronóstico del menor.

ABSTRACT Staphylococcal scalded skin syndrome is a rare pathology, which mainly affects pediatric population. Although in most cases it has a favorable outcome, making a good differential diagnosis and early antibiotic management are crucial for a good prognosis. Objective: To describe a case of scalded skin syndrome with methicillin-resistant S. aureus bloodstream infection in a newborn. Clinical case: A 25-day-old female, born at term and with no relevant perinatal history, presented with fever, generalized scaly erythematous dermatosis, eyelid and lower limb edema. She is hospitalized with a diagnosis of late neonatal sepsis and scalded skin syndrome. Report of blood cultures with growth of methicillin-resistant S. Aureus, managed with vancomycin for 14 days. Control cultures were negative, satisfactory evolution and hospital discharge without complications. Conclusions: Despite the low incidence of scalded skin syndrome, it is important to include S. aureus toxin infections in the differential diagnosis of fever and late-onset dermatoses in the newborn. The identification and early treatment are of great importance in the prognosis of the child.

[Unusual Organophosphate Poisoning: Transplacental Route]. / Intoxicación inusual por organofosforados: Vía transplacentaria.

INTRODUCTION: Accidental or intentional intoxication by organophosphates, which are toxic substances that inhibit acetylcholinesterase, constitutes a serious public health problem worldwide, with a greater impact in developing countries. Chronic intoxication during pregnancy with alterations in neurodevelopment and fetal growth has been described. OBJECTIVE: To describe an unusual case of transplacentally acquired organophosphorus poisoning, highlighting the clinical presentation, the management with atropine, and the neurological outcome. CLINICAL CASE: 36-weeks premature newborn, whose mother presented acute intentional organophosphorus poisoning 17 hours before birth. The patient was born by emergency C-section, without respiratory distress, with bradycardia, hypotonia, miosis, and bron- chorrhea, as well as clinical signs and laboratory evidence of acute poisoning, with severe metabolic acidosis, and decreased cholinesterase activity. She required advanced resuscitation, management in the Neonatal Intensive Care Unit with invasive ventilation, inotropes, and repeated doses of atropine. She evolved with left hemiparesis and convulsive syndrome that was treated with phenobarbital. She was discharged at 34 days of life with her mother, under custody and supervision of social and family welfare. Treatment and follow-up were suspended until her first year of life when her custody was transferred to an aunt. In neurological control at 18 months, she presented persistence of hemiparesis and speech-language delay, without new seizures. CONCLUSIONS: Organophosphorus poisoning is very rare in the neonatal period and due to the absence of guidelines for the management of this type of patients its treatment is challenging and must be individualized, multidisciplinary, evaluating the risk and benefit of each intervention.

Factores predisponentes para ictericia neonatal en los pacientes egresados de la UCI neonatal, Hospital Infantil los Ángeles de Pasto / Predisposing factors for neonatal jaundice in patients discharged from neonatal ICU, in los Ángeles children's Hospital in Pasto

Resumen Introducción: La ictericia neonatal es una de las condiciones más frecuentes en los recién nacidos, a pesar de ser benigna, un tratamiento inadecuado puede llegar a ser nocivo para el paciente. Objetivo: Determinar los factores predisponentes de ictericia neonatal en los pacientes egresados de la UCI neonatal del Hospital Infantil Los Ángeles de la ciudad de Pasto (Nariño) en el periodo enero de 2007 - agosto de 2011. Materiales y métodos: Estudio observacional, descriptivo, retrospectivo y cuantitativo. Se estudiaron 608 historias clínicas de neonatos egresados con diagnóstico de ictericia neonatal; las variables estudiadas se analizaron con el complemento de Excel, XLSTAT-Pro 7.5.2. Resultados: Los principales factores predisponentes encontrados en la población, fueron la lactancia materna exclusiva y el género masculino en un 87%, y 57,40% respectivamente, además 90,79% fueron recién nacidos a término, 92,93% tuvieron peso adecuado para la edad gestacional y 54,93% presentaron ictericia neonatal entre los 2 y 7 días de vida extrauterina. Conclusiones: La ictericia neonatal está asociada a factores maternos y neonatales, tanto modificables como no modificables, que pueden ser abordados con estrategias adecuadas para reducir la carga de enfermedad.

Abstract Introduction: Neonatal jaundice is one of the most common conditions in newborns; however, improper treatment can be harmful to the patient, despite being benign. Objective: To determine the predisposing factors of neonatal jaundice in patients discharged from the neonatal ICU of Los Angeles children's Hospital in the city of Pasto (Nariño) between January 2007and August 2011. Materials and methods: An observational, descriptive, retrospective and quantitative study was conducted. 608 clinical histories of discharged infants diagnosed with neonatal jaundice were studied. The variables studied were analyzed with the complement of Excel, XLSTAT-Pro 7.5.2. Results: The main predisposing factors found in the population were exclusive breastfeeding and male gender in 87%, and 57.40% respectively; besides, 90.79% were newborns at term, 92.93% had adequate weight for their gestational age and 54.93% presented neonatal jaundice between 2 and 7 days of extrauterine life. Conclusions: Neonatal jaundice is associated with both modifiable and non-modifiable maternal and neonatal factors that can be addressed with appropriate strategies to reduce the burden of disease.
