ABSTRACT

Fundamento: Las infecciones del sistema nervioso central constituyen una importante causa de morbilidad y mortalidad neurológica. La púrpura fulminante o meningococemia es una enfermedad grave que evoluciona aseveras complicaciones y secuelas, sin embargo, es infrecuente que ocurra momificación o amputación naturalde los dedos de las manos y los pies.Objetivo: Describir el caso de un paciente con meningococemia fulminante, al cual se le momificaron de manera natural las falanges de las manos y los pies como consecuencia de la enfermedad.Presentación del caso: Se presenta un paciente de 18 años de edad que fue diagnosticado conmeningococemia. Clínicamente presentó fiebre, cefalea intensa, lesiones purpúrico hemorrágicas, petequias y hematomas en piel, evolutivamente shock séptico y disfunción múltiple de órganos. Posterior a 16 días de estadía en sala egresó vivo del hospital, pero con secuelas caracterizadas por momificación de las falanges de las manos y los pies.Conclusiones: La meningococemia es una enfermedad aguda, potencialmente mortal y se reporta mayormente en la edad pediátrica. Entre los sobrevivientes es infrecuente que ocurra la momificación de las falanges de las manos y los pies, como ocurrió en el caso reportado. [AU]

ABSTRACT

Introducción: el dolor cervical es un síntoma encontrado frecuentemente en la práctica clínica. Uno de los tratamientos más frecuente para este padecimiento,específicamente para las hernias discales, es la discectomía con artrodesis cervical anterior. El uso del injerto de cresta iliaca resulta la práctica habitual en Cuba, aunque se recoge el antecedente del uso de otros materiales.Objetivo: comparar el comportamiento de injertos de cortical bovina, hidroxiapatita,polimetilmetacrilato, cromo-cobalto-molibdeno y el auto injerto tricortical de crestailiaca en el espacio intervertebral C6-C7 ante las cargas habituales de la columna cervical.Métodos: se realizó un estudio experimental mediante la simulación numérica según el método de los elementos finitos, los diferentes injertos se sometieron a las cargas axiales recomendadas por las normas ASTM F2423-11e ISO 18192-1.2011mediante elsoftware Free CAD 0.18 en el espacio C6-C7 de un modelo experimental de la columna cervical.Resultados: los mayores esfuerzos soportados por diferentes injertos fueron:tricortical: 19190 kPa, xenoinjerto: 13210 kPa, hidroxiapatita sin porosidad y con unaporosidad del 50porciento: 41500 kPa y 45100 kPa, respectivamente, polimetilmetacrilato:4440 kPa y cromo-cobalto-molibdeno: 148470 kPa.Conclusiones: todos los injertos resistieron la carga aplicada excepto el dehidroxiapatita con un 50porciento de porosidad. El injerto tricortical describió un comportamiento adecuado. Todos provocaron tensiones en las vértebras colindantes,en mayor medida los de polimetilmetacrilato y cromo-cobalto-molibdeno.[AU]

ABSTRACT

UNLABELLED: Nitric oxide (NO) has been implicated in cirrhosis and might be implicated in renal failure end-stage cirrhosis. AIM: Our aim was to evaluate NO role in renal failure induced during decompensated cirrhosis, using the following inhibitors: aminoguanidine (AG), a specific inducible nitric oxide synthase (iNOS) inhibitor and NG-nitro-l-arginine methyl ester (L-NAME), a nonselective blocker of NOS isoforms. METHODS: Endothelial (eNOS) and iNOS gene expression was analyzed by reverse transcriptase-polymerase chain reaction. Cirrhotic rats received a single intragastric dose of CCl(4) to induce acute liver damage (ALD). RESULTS: After ALD, aspartate aminotransferase highest levels were observed in rats treated with AG and ALT in rats treated with L-NAME. Inhibitors decreased creatinine serum levels to normal values and serum sodium levels re-established after the third day of ALD. L-NAME diminished (P<0.05) eNOS RNA renal expression. Renal iNOS with no inhibitor was overexpressed but was down-regulated by AG treatment. Liver eNOS RNA expression had a decreased expression before ALD in cirrhotic rats, but L-NAME treatment down-regulated eNOS after ALD. AG induced an important iNOS liver decrease. CONCLUSION: Both inhibitors improved renal function, although AG displayed a better effect and did not aggravate liver function. We concluded that NOS isoforms are implicated in the renal pathophysiologic events induced by ALD.

ABSTRACT

INTRODUCTION: Liver transplant (LT) is today a first choice procedure in a group of hepatic diseases in their acute and chronic terminal stages. It is not, however, a technique that is completely free of complications and those of a neurological nature constitute between 8 47% of those reported. AIMS. The purpose of this study is to present the immediate neurological complications (NC) found in our patients, as well as to determine the predictive factors and their relation to the mortality rate. PATIENTS AND METHODS: From the medical records of 26 patients who received LT at the CIMEQ (July 1999 December 2001), we collected a group of variables related to the donor, the surgical procedure and the post operative period and associated them to the occurrence of NC while these patients were in the ICU. RESULTS: NC were found in 16 patients (61.5%), the most frequent being encephalopathy (30.8%), tremor (26.9%), and convulsions (19.2%). No relation was found between the presence of NC and prior hepatic encephalopathy, the use of a suboptimal donor, nor did it represent a significant increase in the mortality rate. There was a significant relation with LT to recipients rated as grade C on the Child Pugh classification system, the presence of intraoperative hypotension (p= 0.0164) and primary dysfunction of the liver graft (p= 0.041). CONCLUSIONS: NC represented a significant cause of morbidity in the period following a liver transplant in our series, although they had no significant repercussion on the mortality rate. Their presence is related to variables concerning the recipient, the surgical procedure itself and the immediate post operative period.

ABSTRACT

Introducción. El trasplante hepático (TH) es hoy en día un procedimiento de elección en un grupo de enfermedades hepáticas agudas y crónicas en estadio terminal. Sin embargo, no es una técnica exenta de complicaciones; las neurológicas se comunican entre el 8 y el 47 por ciento. Objetivos. Presentar las complicaciones neurológicas (CN) inmediatas encontradas en nuestros pacientes, así como determinar los factores predictivos y su relación con la mortalidad. Pacientes y métodos. De los expedientes clínicos de los 26 pacientes que fueron tributarios de TH en el CIMEQ (julio 1999-diciembre 2001), se recogió un grupo de variables relacionadas con el donante, el acto quirúrgico y el posoperatorio, y se relacionó con la presencia de CN durante su estancia en la UCI. Resultados. Encontramos CN en 16 pacientes (61,5 por ciento); las más frecuentes fueron la encefalopatía (30,8 por ciento), temblores (26,9 por ciento), y convulsiones (19,2 por ciento). No se encontró relación entre la presencia de CN, y encefalopatía hepática previa o con uso de donante subóptimo, ni representó un aumento significativo en la mortalidad. Existió una relación significativa con el TH a receptores grado C de la clasificación de Child-Pugh, la presencia de hipotensión intraoperatoria (p = 0,0164), y de disfunción primaria del injerto hepático (p = 0,041). Conclusiones. En nuestra serie, las CN representaron una morbilidad significativa en el postrasplante hepático, sin repercusión significativa en la mortalidad. Su presencia se relaciona con variables del receptor, del acto operatorio y del posoperatorio inmediato (AU)

ABSTRACT

A case of calcified gastric adenocarcinoma is presented. It is of clinical interest because of its rareness. Histologically a mucus-secreting adenocarcinoma with lakes of intercellular mucin was found. The need to take this lesion into account in the differential diagnosis of the calcifications in the upper left quadrant, is emphasized.
