Spondylothoracic dysplasia (STD, MIM#277300) is an autosomal recessive disorder with high prevalence in the Puerto Rican population. It is generally regarded as a lethal condition. Since Jarcho and Levin described it in 1938, it has been referred to as spondylocostal dysplasia, costovertebral dysplasia, Jarcho-Levin syndrome and STD. We have prospectively characterized 27 patients with STD by detailed physical examination, pedigree analysis, thoracic CT scans, and pulmonary function tests (PFTs). Diagnoses were established using spinal radiographs and 3-D reconstructive CT scans to demonstrate fusion of the ribs at the costo-vertebral junction with a fan-like (crab-like) configuration of the thorax. Vertebral segmentation and formation defects were seen throughout the spine with a decrease in the number of vertebral bodies. Characteristic vertebral shape consisted of a decrease in antero-posterior diameter and an increase in lateral length, giving the vertebra a sickle shape. Eight out of 18 prospectively follow patients died within the first 6 months of life, a 44% mortality rate. Cause of death was respiratory insufficiency secondary to pneumonia and pulmonary restriction. This is an important finding since the vast majority of STD syndrome patients cited in the medical literature have died in the newborn and early childhood periods. Age of the remaining patients ranged from 4 months to 47 years. This represents the largest collection of patients with STD reported and it has allowed us to determine a detailed phenotype. Given 56% survival at 6 months, we show that STD is not a lethal syndrome.
Introducción: la resistencia antimicrobiana es un fenómeno global que afecta a los individuos y atenta contra la recuperación de pacientes en estado grave. Objetivo: determinar el grado de resistencia antimicrobiana de los microorganismos que se aíslan en las Unidades de Cuidados Intensivos. Diseño metodológico: observacional descriptivo de corte transversal sobre una serie de microorganismos aislados en muestras biológicas procedentes de las Unidades de Cuidados Intensivos del Hospital “Dr. Gustavo Aldereguía Lima” de Cienfuegos, durante el año 2018. El universo fue de 620 gérmenes. Se analizaron variables como microorganismo, muestra biológica y antimicrobiano. Se realizó el procesamiento estadístico a partir del SPSS 21.0 para mejor representación de los resultados. Resultados: Acinetobacter baumannii fue el germen más aislado (24,1%). Se evidenció una resistencia marcada a la ampicilina, cefazolina, cefuroxima y ceftazidima, con porcentajes superiores al 50%; dentro de los medicamentos más efectivos, resaltaron linezolid y vancomicina para gram positivos. Conclusiones: existen microorganismos resistentes y multirresistentes circulando en las terapias del hospital, su vigilancia debe ser prioritaria, los gérmenes más frecuentes fueron Acinetobacter baumannii, Staphylococcus coagulasa negativo, Klebsiella pneumoniae, entre otros. Las bacterias mostraron una resistencia marcada a la ampicilina, cefazolina, cefuroxima, ceftazidima; y sensibilidad a linezolid y vancomicina.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
