Cough impairment and risk of postoperative pulmonary complications after open upper abdominal surgery.

Background: Cough impairment is often described as part of the pathophysiological basis of postoperative pulmonary complications (PPCs). However, there have been few studies examining cough effectiveness and its relationship with PPCs following open upper abdominal surgery. The goal of this study was to estimate (1) changes in cough efficacy after upper abdominal surgery through the assessment of peak cough flow and (2) the extent to which cough impairment is associated with postoperative pain, FVC, and risk of PPCs.

Evaluation of intraorbital injection of rituximab for treatment of primary ocular adnexal lymphoma: a pilot study.

An interventional pilot study to assess the tolerability and activity of the intralesional injection of rituximab, a chimeric mAb that targets the CD20 antigen, in patients with orbital B-cell lymphoma. Five patients received four intralesional injections (one injection a week) of rituximab together with ropivicaine 2%. Side-effects and tumor response were assessed after each injection and during the follow-up (20 months).

Utilization of positive-pressure devices for breathing exercises in the hospital setting: a regional survey in São Paulo, Brazil.

Background: The use of breathing exercises with positive-pressure devices during hospitalization aims to prevent the development of nosocomial pulmonary complications or to facilitate recovery from pulmonary conditions already present. Although this type of intervention has potential benefits and theoretical advantages over more conventional respiratory physiotherapy techniques, the literature on the effects of breathing exercises with positive-pressure is controversial and inconsistent.

Objective: To evaluate the extension of the use of breathing exercises with positive-pressure devices by physiotherapists in São Paulo, Brazil.

Mydriasis induced by sub-Tenon's ropivacaine injection in patients undergoing strabismus surgery.

Purpose: To investigate the effects of sub-Tenon's capsule ropivacaine injection on pupillary diameter in strabismus surgery.

Methods: A total of 16 patients were randomly assigned to 2 groups. The ropivacaine group (R) received sub-Tenon's ropivacaine 1% (2.

Atypical presentation of a case of solitary fibrous tumor of the orbit.

Purpose: To describe a rare case of solitary fibrous tumor of the orbit in a child, clinically misdiagnosed as arterious hemangioma.

Methods: A nine-year-old child presented a hard-elastic palpable mass located in the right inferotemporal orbit. Computed tomography, orbital pulsed-wave Doppler and internal carotid artery angiography consented diagnosis of high-vascularization mass probably related to arterious hemangioma with feeder vessel arising from a branch of ophthalmic artery.

Association of a single-nucleotide polymorphism in the pregnane X receptor (PXR 63396C-->T) with reduced concentrations of unboosted atazanavir.

This study investigated pregnane X receptor polymorphisms in relation to unboosted atazanavir plasma concentrations in 2 cohorts of patients. The polymorphism 63396T-->C predicted concentrations below the minimum effective concentration (150 ng/mL) with odds ratios of 18 (P = .008) and 5.

Surgical treatment of obstruction of the nasolacrimal ducts in patients with anatomical endonasal variants.

The presence of anatomical endonasal variants (concha bullosa, nasal septal deviation, or hypertrophic turbinates) may cause more complications in patients with epiphora who have external dacryocystorhinostomy (DCR). The purpose of this study was to assess the results of surgical placement of a stent in 28 patients. They were randomised into two groups and had either DCR or placement of a Song's polyurethane stent.

Acute onset concomitant esotropia: sensorial evaluation, prism adaptation test, and surgery planning.

Background And Objective: Acute acquired concomitant esotropia is a rare form of strabismus that usually presents during infancy or early childhood with diplopia and minimal refractive error. The aim of this study was to evaluate the response to the prism adaptation test in a group of normosensorial patients with acute acquired concomitant esotropia and to determine its predictive value for surgical outcome.

Patients And Methods: Six patients (median age, 11 .
