Knowledge of symptoms and delays in diagnosis of extrapulmonary tuberculosis patients in North Shewa zone, Ethiopia.

Introduction: Delayed diagnosis contributes to the high burden and transmission of tuberculosis and extrapulmonary tuberculosis (EPTB) and continued to be a major public health problem in Ethiopia. Currently, there is insufficient knowledge on the contributing factors to diagnostic delay of EPTB patients in healthcare settings in Ethiopia, because of unique cultural and societal issues in this country. This study assessed patients' knowledge of symptoms and contributing factors of delay in diagnosis of EPTB patients at selected public health facilities in North Shewa zone, Ethiopia.

Satisfaction, functional outcomes and predictors in hip arthroscopy: a cohort study.

Introduction: Hip arthroscopy is not always successful, leading to high rates of total hip arthroplasty (THA) after arthroscopy. The aim of this study was to identify risk factors for THA, revision arthroscopy and low patient satisfaction and to compare outcomes of the different procedures of primary hip arthroscopy.

Methods: A total of 91 primary hip arthroscopy procedures in 90 patients (66% female) were analysed.

A Multicomponent Nonpharmacological Intervention to Prevent Delirium for Hospitalized People with Advanced Cancer: A Phase II Cluster Randomized Waitlist Controlled Trial (The PRESERVE Pilot Study).

Delirium is a common debilitating complication of advanced cancer. To determine if a multicomponent nonpharmacological delirium prevention intervention was feasible for adult patients with advanced cancer, before a phase III (efficacy) trial. Phase II (feasibility) cluster randomized controlled trial.

Abdominal Wall Pain or Irritable Bowel Syndrome: Validation of a Pediatric Questionnaire.

Objectives: A questionnaire study demonstrated that some adult patients who were diagnosed with irritable bowel syndrome (IBS) were in fact having an abdominal wall pain syndrome, such as anterior cutaneous nerve entrapment syndrome (ACNES). The aim of the present study was to investigate whether a pediatric version of this questionnaire was useful in diagnosing abdominal wall pain syndromes in children with chronic abdominal pain (CAP).

Methods: An 18-item questionnaire was tested in 3 groups of children with CAP: group 1, children who underwent surgery for ACNES (n = 42); group 2, children who were found to have ACNES after an outpatient analysis (n = 57); and group 3, children diagnosed with IBS (n = 53).

Accuracy of the Precision Saw versus the Sagittal Saw during total knee arthroplasty: A randomised clinical trial.

Background: The aim of this study was to compare the accuracy of the oscillating tip saw system (Precision Saw=PS) with the more conventional fully oscillating blade system (Sagittal Saw=SS) during computer-assisted total knee arthroplasty (CAS-TKA).

Methods: A prospective, randomised, controlled trial included 58 consecutive patients who underwent primary CAS-TKA and were randomly assigned in the PS group or the SS group to compare the accuracy of both blades. The primary outcome was the difference between the intended cutting planes and the actual cutting planes in degrees (°) in two planes of both the femur and the tibia.
