Superior functional outcome after radical cystectomy and orthotopic bladder substitution with restrictive intraoperative fluid management: a followup study of a randomized clinical trial

PURPOSE Continuous intraoperative norepinephrine infusion combined with restrictive deferred hydration improves surgical field visibility, and significantly decreases intraoperative blood loss and postoperative complications in patients undergoing radical cystectomy and urinary diversion. We determined whether the intraoperative fluid regimen would affect functional results (continence and erectile function) 1 year after orthotopic ileal bladder substitution. MATERIALS AND METHODS We analyzed a subgroup of 93 patients who received an ileal orthotopic bladder substitute. The subgroup was part of a randomized trial in 167 patients initially allocated to continuous norepinephrine administration starting with 2 μg/kg per hour combined with 1 ml/kg per hour initially and 3 ml/kg per hour crystalloid infusion after cystectomy (norepinephrine/low volume group of 51) or a standard crystalloid infusion of 6 ml/kg per hour throughout surgery (42 controls). We prospectively assessed daytime and nighttime continence, and erectile function 1 year postoperatively in the 93-patient subgroup. RESULTS Daytime continence was reported by 44 of 51 patients (86%) in the norepinephrine/low volume group and by 27 of 42 controls (64%) (p = 0.016), and nighttime continence was reported by 38 (75%) and 25 (60%), respectively (p = 0.077). Erectile function recovery was reported by 26 of 33 preoperatively potent patients (79%) in the norepinephrine/low volume group and by 11 of 29 controls (38%) (p = 0.002). CONCLUSIONS Patients who undergo radical cystectomy and orthotopic bladder substitution with continuous norepinephrine infusion and restrictive hydration during surgery have significantly better daytime continence and erectile function 1 year postoperatively.

Promotion of literacy skills in early childhood: a follow-up study from kindergarten to grade 1

Several researchers have shown that invented spelling activities in kindergarten foster preschool children’s early literacy skills. However, few studies have assessed its impact on learning to read and write in the first year of primary school. Our goal was to analyse the impact of an invented spelling programme with kindergarteners on their literacy skills until the end of Grade 1. A follow-up study was conducted with 45 five-year-old Portuguese children attending two classes of two schools in Lisbon. The teaching effect was controlled as children from each class were randomly assigned into two groups (experimental/control) — equivalent on letter knowledge, cognitive abilities and phonological awareness. The participants were assessed in kindergarten with a pre-test, immediate post-test and delayed post-test (spelling; reading; phonemic awareness) and at the end of Grade 1 (spelling; reading). The experimental group participated in invented spelling sessions, while control children participated in storytelling activities. Data analysis revealed statistically significant differences between the two groups. The experimental group scored higher, not only in kindergarten but also in the follow-up year for all literacy measures.

Prevalencia de desordenes musculo-esqueléticos y su asociación con factores ergonómicos en trabajadores administrativos de una institución educativa de nivel superior 2015

Objetivo. Establecer la prevalencia de Desordenes Musculo Esqueléticos(DME) y su asociación con factores ergonómicos (postura, manipulación de carga y trabajo repetitivo) en trabajadores administrativos de una Institución Educativa de Nivel Superior (IENS). Métodos. Se realizó un estudio descriptivo de corte transversal a 146 trabajadores de una IENS de la ciudad de Neiva (Huila), entre Abril y Mayo de 2015. Para la recolección de la información se utilizaron dos instrumentos: un instrumento para la caracterización sociodemográfica y ocupacional y el cuestionario estandarizado para identificar daños y exposición a riesgos ergonómicos en el trabajo (ERGOPAR). Resultados. El 90,4 % de los trabajadores presentaron molestia o dolor en alguna de las áreas del cuerpo, dentro de las cuales las más afectadas fueron las zonas del Cuello, hombros y/o espalda dorsal con el 79,9%, la espalda lumbar con el 65,8% y las manos y/o muñecas con el 49,3%. Conclusiones. Se encontró una asociación entre la exposición a factores ergonómicos y la presencia de DME, indicando que las posturas de trabajo forzadas o prolongadas y la manipulación de cargas representan un alto riesgo biomecánica para los trabajadores, lo cual se puede ver reflejado a mediano o largo plazo con el desarrollo de trastornos o enfermedades que pueden llegar a ser incapacitantes para los trabajadores, afectando su calidad de vida y su productividad laboral.

Undifferentiated Spondyloarthritis: A Longterm Followup

Objective. To analyze the longterm followup of a series of Brazilian patients with undifferentiated spondyloarthritis (uSpA). Methods. Prospective study analyzing a group of 111 patients with the diagnosis of uSpA, fulfilling the European Spondylarthropathy Study Group and the Amor criteria, who were followed for 5 to 10 years in a single university referral center. Patients had their outcome analyzed at 5, 7, and 10 years. Results. There was a predominance of men (81.1%), white ethnicity (78.4%), and positive HLA-B27 (61.3%), with a mean age at onset of 27.2 years. Twenty-seven patients presented development to ankylosing spondylitis (AS; 24.3%) and 3 to psoriatic arthritis (PsA; 2.7%), while 25 patients (22.5%) went into remission during the followup. Univariate logistic regression analysis revealed that ethnicity, HLA-B27, buttock pain, inflammatory low back pain, ankle involvement, grade I sacroiliitis at the beginning of the study, and the use of sulfasalazine were statistically associated with progression to AS. Multivariate logistic regression analysis revealed that HLA-B27 (p = 0.035, OR 6.720.95% CI 11.45-39.43) and buttock pain (p = 0.009, OR 6.211, 95% CI 1.591-24.25) were statistically associated with progression to AS. Conclusion. In a longterm followup of 111 Brazilian patients with uSpA, HLA-B27 and buttock pain were significant predictors of progression to a definite disease.

Long-Term Outcome and Prognostic Factors of Juvenile Dermatomyositis: A Multinational, Multicenter Study of 490 Patients

Objective. To investigate the long-term outcome and prognostic factors of juvenile dermatomyositis (DM) through a multinational, multicenter study. Methods. Patients consisted of inception cohorts seen between 1980 and 2004 in 27 centers in Europe and Latin America. Predictor variables were sex, continent, ethnicity, onset year, onset age, onset type, onset manifestations, course type, disease duration, and active disease duration. Outcomes were muscle strength/endurance, continued disease activity, cumulative damage, muscle damage, cutaneous damage, calcinosis, lipodystrophy, physical function, and health-related quality of life (HRQOL). Results. A total of 490 patients with a mean disease duration of 7.7 years were included. At the cross-sectional visit, 41.2-52.8% of patients, depending on the instrument used, had reduced muscle strength/endurance, but less than 10% had severe impairment. Persistently active disease was recorded in 41.2-60.5% of the patients, depending on the activity measure used. Sixty-nine percent of the patients had cumulative damage. The frequency of calcinosis and lipodystrophy was 23.6% and 9.7%, respectively. A total of 40.7% of the patients had decreased functional ability, but only 6.5% had major impairment. Only a small fraction had decreased HRQOL. A chronic course, either polycyclic or continuous, consistently predicted a poorer outcome. Mortality rate was 3.1%. Conclusion. This study confirms the marked improvement in functional outcome of juvenile DM when compared with earlier literature. However, many patients had continued disease activity and cumulative damage at followup. A chronic course was the strongest predictor of poor prognosis. These findings highlight the need for treatment strategies that enable a better control of disease activity over time and the reduction of nonreversible damage.

Kératite varicelleuse séquellaire [Followup of chicken pox keratitis. Anatomic-clinical case report].

Chicken pox is a very common infectious disease in children. Its corneal involvement is less serious than with measles, which may lead to blindness in numerous developing countries. However, with occasional cases occur. A case of a 59-year-old male patient whose left cornea was involved during a chicken pox infection at the age of 7 is reported. More recently, the vision of the right eye was normal at 20/20 and reduced to visual perception in the affected left eye. Corneal sensitivity was maintained in the left eye, which, however exhibited a central epithelial defect. A central round opacity of the left corneal stroma was believed to be the scar resulting from a previous disciform keratitis. The left central cornea was thinned and there was neither an anterior chamber flare nor new corneal vessels. This corneal condition required a corneal allograft, performed quickly because of the potential risk of perforation. Histopathological study of the corneal button showed a central corneal thinning with an increase in epithelial thickness. The corneal stroma was disorganized, with irregular collagen bundles. No inflammatory cells could be observed, however. All the histopathological changes observed were those of a corneal scar.

Three-dimensional computed cementless custom femoral stems in young patients: midterm followup.

We prospectively evaluated the results of our custom cementless femoral stems to ascertain whether this technology produced reasonable clinical function, complication rates, and loosening rates at midterm. Fifty-seven consecutive patients had surgery in 62 hips for primary osteoarthritis at a mean age of 57 years using a three-dimensional computed custom cementless stem. Patients were reviewed at a mean followup of 94.9 months. At review, the mean Harris hip score was 98.8 points (range, 84-100) compared with 61.1 (range, 28-78) points preoperatively. No patient complained of thigh pain. No migration or subsidence was observed. All stems were considered stable according to the radiographic criteria defined by Engh et al. There were no dislocations, no infections, and no reoperations. Our results are comparable with published results from clinical and radiologic points of view. Two problems remain unsolved: the price of a custom stem is twice as expensive as a standard stem; and we need longer term results before definitely recommending this technology as a reasonable alternative to current arthroplasties in younger patients. The data support the continued exploration of this technology with controlled clinical followup. LEVEL OF EVIDENCE: Therapeutic study, Level II-1 (prospective cohort study).

Preliminary results of venlafaxine exposure in pregnancy, a multicenter prospective cohort ENTIS study

Introduction: Venlafaxine (Efexor®) is a serotonin and noradrenaline reuptake inhibitor (SNRI) used for the treatment of depression and anxiety disorders. The limited data on the use of venlafaxine in human pregnancy do not indicate an increased risk of congenital malformations. The main purpose of the study is to assess the rate of major malformations after first trimester exposure to venlafaxine. Methods: This multicenter, prospective cohort study was performed using data from nine centers who are member of the European Network of Teratology Information Services (ENTIS). Data on pregnancy and pregnancy outcome of women who used venlafaxine in pregnancy were collected during individual risk counseling. Standardized procedures for data collection and followup were used by each center. Results: Follow up data were collected on 744 pregnancies of womenwhoused venlafaxine during gestation. In 583 (78.4%) cases the exposure had occurred at least in the first trimester. In total, there were 600 live births (5 twins), 85 spontaneous abortions, 57 elective terminations of pregnancy, 5 fetal deaths, and 2 ectopic pregnancies. The overall rate of major malformations after first trimester exposure and excluding chromosomal and genetic disorders was 3.2% (16/500) in all pregnancies ending in delivery, pregnancy terminations or fetal deaths with fetal-pathological examination. Among live births the malformation rate was 2.7% (13/490). We observed no increased risk for organ specific malformations. Conclusions: The present study indicates that venlafaxine is not a major human teratogen.

A retrospective study of cholinesterase inhibitors for Alzheimer's disease : the effect of cerebrovascular disease on patient outcomes and the impact of biases on the results.

Introduction: La démence peut être causée par la maladie d’Alzheimer (MA), la maladie cérébrovasculaire (MCEREV), ou une combinaison des deux. Lorsque la maladie cérébrovasculaire est associée à la démence, les chances de survie sont considérées réduites. Il reste à démontrer si le traitement avec des inhibiteurs de la cholinestérase (ChEIs), qui améliore les symptômes cognitifs et la fonction globale chez les patients atteints de la MA, agit aussi sur les formes vasculaires de démence. Objectifs: La présente étude a été conçue pour déterminer si la coexistence d’une MCEREV était associée avec les chances de survie ou la durée de la période jusqu’au placement en hebergement chez les patients atteints de la MA et traités avec des ChEIs. Des études montrant de moins bons résultats chez les patients souffrant de MCEREV que chez ceux n’en souffrant pas pourrait militer contre l’utilisation des ChEIs chez les patients atteints à la fois de la MA et la MCEREV. L'objectif d'une seconde analyse était d'évaluer pour la première fois chez les patients atteints de la MA l'impact potentiel du biais de « temps-immortel » (et de suivi) sur ces résultats (mort ou placement en hebergement). Méthodes: Une étude de cohorte rétrospective a été conduite en utilisant les bases de données de la Régie de l’Assurance Maladie du Québec (RAMQ) pour examiner la durée de la période jusqu’au placement en hebergement ou jusqu’au v décès des patients atteints de la MA, âgés de 66 ans et plus, avec ou sans MCEREV, et traités avec des ChEIs entre le 1er Juillet 2000 et le 30 Juin 2003. Puisque les ChEIs sont uniquement indiquées pour la MA au Canada, chaque prescription de ChEIs a été considérée comme un diagnostic de la MA. La MCEREV concomitante a été identifié sur la base d'un diagnostic à vie d’un accident vasculaire cérébral (AVC) ou d’une endartériectomie, ou d’un diagnostic d'un accident ischémique transitoire au cours des six mois précédant la date d’entrée. Des analyses séparées ont été conduites pour les patients utilisant les ChEIs de façon persistante et pour ceux ayant interrompu la thérapie. Sept modèles de régression à risque proportionnel de Cox qui ont varié par rapport à la définition de la date d’entrée (début du suivi) et à la durée du suivi ont été utilisés pour évaluer l'impact du biais de temps-immortel. Résultats: 4,428 patients ont répondu aux critères d’inclusion pour la MA avec MCEREV; le groupe de patients souffrant seulement de la MA comptait 13,512 individus. Pour le critère d’évaluation composite considérant la durée de la période jusqu’au placement en hebergement ou jusqu’au décès, les taux de survie à 1,000 jours étaient plus faibles parmi les patients atteints de la MA avec MCEREV que parmi ceux atteints seulement de la MA (p<0.01), mais les différences absolues étaient très faibles (84% vs. 86% pour l’utilisation continue de ChEIs ; 77% vs. 78% pour la thérapie avec ChEIs interrompue). Pour les critères d’évaluation secondaires, la période jusqu’au décès était plus courte chez les patients avec la MCEREV que sans la MCEREV, mais la période jusqu’au vi placement en hebergement n’était pas différente entre les deux groupes. Dans l'analyse primaire (non-biaisée), aucune association a été trouvée entre le type de ChEI et la mort ou le placement en maison d'hébergement. Cependant, après l'introduction du biais de temps-immortel, on a observé un fort effet différentiel. Limitations: Les résultats peuvent avoir été affectés par le biais de sélection (classification impropre), par les différences entre les groupes en termes de consommation de tabac et d’indice de masse corporelle (ces informations n’étaient pas disponibles dans les bases de données de la RAMQ) et de durée de la thérapie avec les ChEIs. Conclusions: Les associations entre la coexistence d’une MCEREV et la durée de la période jusqu’au placement en hebergement ou au décès apparaissent peu pertinentes cliniquement parmi les patients atteints de la MA traités avec des ChEIs. L’absence de différence entre les patients atteints de la MA souffrant ou non de la MCEREV suggère que la coexistence d’une MCEREV ne devrait pas être une raison de refuser aux patients atteints de la MA l’accès au traitement avec des ChEIs. Le calcul des « personne-temps » non exposés dans l'analyse élimine les estimations biaisées de l'efficacité des médicaments.

Predicting violence in schizophrenia: a prospective study

Background: People with schizophrenia are more violent than the general population, but this increased risk is attributable to the actions of a small subgroup. Identifying those at risk has become an essential part of clinical practice. Aims: To estimate the risk factors for assault in patients with schizophrenia. Methods: Two hundred seventy-one patients with schizophrenia were interviewed using an extensive battery of instruments. Assault was measured from multiple data sources over the next 2 years and criminal records were obtained. Multiple sociodemographic and clinical variables measured at baseline were examined as possible predictors of assault during follow-up. Results: Sixty-nine (25%) patients committed assault during the 2-year followup. The model that best predicted assault included a history of recent assault (OR 2.33, 95% CI 1.17-4.61), a previous violent conviction (OR 2.02, 95% CI 1.04-3.87), having received special education (OR 2.76, 95% CI 1.22-6.26) and alcohol abuse (OR 3.55, 95% CI 1.24-10.2). Conclusions: Previously established risk factors including a history of violence and alcohol abuse are replicated in this study. Although low premorbid IQ did not predict violence, a need for special education did. (C) 2003 Published by Elsevier B.V.
