Infective parasitic diseases are a major health problem, particularly among younger children and in subjects of low socioeconomic status.

BackgroundDexmedetomidine infusion improves oxygenation and lung mechanics in patients with chronic obstructive lung disease; however, its effect in patients with restrictive lung disease has not been thoroughly investigated yet. The aim of this work was to evaluate the effects of dexmedetomidine infusion on oxygenation and lung mechanics in morbidly obese patients with restrictive lung disease.MethodsForty-two morbidly obese patients scheduled for bariatric surgery were included in the study. Patients were randomized to receive either dexmedetomidine infusion at a bolus dose of 1mcg/Kg followed by infusion at 1 mcg/Kg/hour for 90 min (Dexmedetomidine group), or normal saline infusion (Control group). Both groups were compared with regard to: oxygenation {P/F ratio: PaO2/fraction of inspired oxygen (FiO2)}, lung compliance, dead space, plateau pressure, blood pressure, and heart rate.ResultsDexmedetomidine group showed significant improvement of the PaO2/FiO2 ratio, and higher lung compliance compared to control group by the end of drug infusion. Dexmedetomidine group demonstrated decreased dead space, plateau pressure, blood pressure, and heart rate compared to control group by the end of drug infusion.ConclusionA 90-min dexmedetomidine infusion resulted in moderate improvement in oxygenation and lung mechanics in morbidly obese patients with restrictive lung disease.Trial registrationclinicaltrials.gov: NCT02843698 on 20 July 2016.

Objective To determine perioperative factors that may optimize the outcome after delayed perineal repair of a pelvic fracture urethral injury (PFUI). Patients and Methods In all, 86 consecutive patients who underwent perineal repair of a PFUI between 2004 and 2011 were prospectively enrolled in this study. The mean (range) patient age was 23 (5–50) years. The mean (range) follow‐up was 5.5 (2–8) years. We examined seven perioperative variables that might influence the outcome including: prior failed treatment, condition of the bulbar urethra, displacement of the prostate, excision of scarred tissues, fixation of the mucosae of the two urethral ends, and the number and size of sutures used for urethral anastomosis. Univariate and multivariate analyses were used to identify factors that influence postoperative outcome. Results Of the patients, 76 (88%) had successful outcomes and 10 (12%) were considered treatment failures. On univariate analysis, four variables were significant factors influencing the outcome: excision of scarred tissues, prostatic displacement, condition of the bulbar urethra and fixation of the mucosae. On multivariate analysis only two remained strong and independent factors namely complete excision of scarred tissues and prostatic displacement in a lateral direction. Conclusions Meticulous and complete excision of scar tissue is critically important to optimise the outcome after perineal urethroplasty. This is particularly emphasised in cases associated with lateral prostatic displacement. Six sutures of 3/0 or 4/0 polyglactin 910 are usually sufficient to create a sound urethral anastomosis. Prior treatment and scarring of the anterior urethra do not affect the outcome.

The ICIQ-BD is a simple, cheap, valid, and reliable method to assess LUTS in everyday clinical practice. However, an agreement between the ICIQ-BD and the ICIQ-MLUTS/FLUTS with regards to daytime frequency and nocturia episode is weak and therefore both are needed in the assessment of patients with LUTS.
