RESUMO
Objetivo: evaluar la frecuencia, los factores pronósticos y el impacto del síndrome de iris laxo intraoperatorio en operaciones de catarata. Métodos: se realizó un estudio de cohorte prospectivo y longitudinal, donde se evaluaron 139 operaciones de catarata realizadas por un solo cirujano, de los cuales 49 ojos (35,3 por ciento) presentaron síndrome de iris laxo intraoperatorio. Se realizó un análisis univariado y multivariado con variables demográficas, antecedentes patológicos personales, uso de medicamentos, características anatómicas del iris, parámetros biométricos y complicaciones intra y posoperatorias. Resultados: en el análisis univariado las variables significativas pronósticas para la aparición de síndrome de iris laxo intraoperatorio fueron: el consumo de psicofármacos (p= 0,001), la cámara anterior estrecha (p= 0,001) y la dilatación pupilar preoperatoria regular o mala (p= 0,001). En el análisis multivariado la cámara estrecha fue, de todas las variables independientes, la que mayor influencia tuvo en la aparición de síndrome de iris laxo intraoperatoriocon una alta significación (p= 0,001). El síndrome de iris laxo intraoperatorio aumentó el riesgo de complicaciones intra y posoperatorias. Conclusiones: con una correcta anamnesis y un examen oftalmológico podemos predecir la ocurrencia de síndrome de iris laxo intraoperatorio durante la cirugía de catarata. El consumo de psicofármacos, la cámara anterior estrecha y la dilatación pupilar preoperatoria regular o mala se pueden considerar factores pronósticos de síndrome de iris laxo intraoperatoriodesde el preoperatorio(AU)
Objective: to evaluate the frequency, the prognostic factors and the impact of the intraoperative floppy iris syndrome in cataract surgery. Method: a prospective and longitudinal cohort study of 139 cataract surgeries performed by the same surgeon, of which 49 eyes (35,3 pércent) presented with intraoperative floppy iris syndrome. An univariate/multivariate analysis was made taking on account demographic, personal history of pathologies, use of medications, anatomical characteristics of the iris, biometric parameters and complications during and after the surgery. Results: in the univariate analysis, the significant prognostic variables for the intraoperative floppy iris syndrome were consumption of antipsychotics (p= 0,001), narrow anterior chamber (p= 0,001) and regular or bad dilated pupil (p= 0,001) before surgery. In the multivariate analysis, the narrow anterior chamber was, among all the independent variables, the most influential for the onset of the intraoperative floppy iris syndrome, with a highly significant association (p= 0,001). The intraoperative floppy iris syndrome increased the intra and postoperative risk for complications. Conclusions: correct interrogation and an eye exam can predict the occurrence of intraoperative floppy iris syndrome during the cataract surgery. The use of antipsychotics, the narrow anterior chamber and regular or bad pupil dilation before the surgery can be considered as prognostic factors for the intraoperative floppy iris syndrome(AU)

El síndrome del niño hipotónico es una entidad bien reconocida por pediatras y neonatólogos. Se refiere a un niño con hipotonía generalizada presente desde el nacimiento o infancia precoz. Es el signo de disfunción neurológica más frecuente en el recién nacido y lactante, resultado de injurias agudas o crónicas a cualquier nivel del sistema nervioso, desde la corteza cerebral al músculo. Por la multiplicidad de causas y condiciones que subyacen a la hipotonía es imprescindible un enfoque ordenado y sistemático en la evaluación del niño hipotónico.
Floppy infant syndrome is a well recognized entity for pediatricians and neonatologists. It refers to a child with decreased muscle tone present at birth or in early infancy. It is the commonest sign of neurological dysfunction in newborns and infants, which can result from acute or chronic injuries at any level of the nervous system from cerebral cortex to muscle. Because of the multiple causes and conditions underlying hypotonia, asystematic assessment is essential in the approach to the floppy infant.

PURPOSE: To investigate the effects of alpha-1 adrenergic receptor antagonists for the treatment of benign prostatic hyperplasia (BPH) regarding potential risks of complications in the setting of cataract surgery. AIM: To address recommendations, optimal control therapy, voiding symptoms and safety within the setting of cataract surgery. MATERIALS AND METHODS: A comprehensive literature review was performed using MEDLINE with MeSH terms and keywords "benign prostatic hyperplasia", "intraoperative floppy iris syndrome", "adrenergic alpha-antagonist" and "cataract surgery". In addition, reference lists from identified publications were reviewed to identify reports and studies of interest from 2001 to 2009. RESULTS: The first report of intraoperative floppy iris syndrome (IFIS) was observed during cataract surgery in patients taking systemic alpha-1 AR antagonists in 2005. It has been most commonly seen related to use of tamsulosin. Changes of medication and washout periods of up to 2 weeks have been attempted to reduce the risk of complications in the setting of cataract surgery. CONCLUSION: Patients under clinical treatment for BPH should be informed about potential risks of this drug class so that it can be discuss with their healthcare providers, in particular urologist and ophthalmologist, prior to cataract surgery.
