Real time monitoring of carbon dioxide levels in surgical helmet systems worn during hip and knee arthroplasty.

Background: Orthopaedic surgical helmet systems (SHS) rely on an intrinsic fan to force clean external air over the wearer. Carbon dioxide (CO) is produced through aerobic metabolism and can potentially accumulate inside the SHS. Levels above 2500 ppm have previously been shown to affect cognitive and practical function.

Selective sonographic screening for developmental dysplasia of the hip - increasing trends in late diagnosis.

There are concerns that selective sonographic screening for developmental dysplasia of the hip (DDH) may be suboptimal. Our aim was to test this hypothesis by identifying trends in presentation and surgical treatment in patients with DDH. This is a retrospective review of children born between 1997-2018 who were treated surgically for DDH at our sub- regional paediatric orthopaedic unit.

Exploring pelvis and thigh movement and coordination patterns during walking in patients after total hip arthroplasty.

Background: Patients after total hip arthroplasty (THA) have altered hip kinematics compared to healthy controls, specifically hip extension and range of motion are lower. Exploring pelvis-thigh coordination patterns and coordination variability may help to elucidate why differences in hip kinematics are evident in patients following THA.

Research Question: Do sagittal plane hip, pelvis and thigh kinematics, and pelvis-thigh movement coordination and coordination variability differ between patients following THA and healthy controls during walking?

Methods: Sagittal plane hip, pelvis and thigh kinematics were collected using a three-dimensional motion capture system while 10 patients who had undergone THA and 10 controls walked at a self-selected pace.

Do patients with well-functioning total hip arthroplasty achieve typical sagittal plane hip kinematics? A proof of concept study.

Background: Total hip arthroplasty (THA) patients have been shown to not achieve normal sagittal plane hip kinematics. However, previous studies have only conducted group level analysis and as such lack the sensitivity to highlight whether individual patients do achieve normal hip kinematics. As such this study looked to determine whether some patients with well-functioning THA achieve typical sagittal plane hip kinematics.

Review of diabetic frozen shoulder.

Frozen shoulder is a painful debilitating condition which can be diagnosed clinically. It is a condition of chronic inflammation and proliferative fibrosis resulting in painful limitation of shoulder movements with classical clinical signs. Diabetic patients are more likely to develop the disease and more likely to require operative management.

Combined effect of toe out gait and high tibial osteotomy on knee adduction moment in patients with varus knee deformity.

Background: Gait adaptations, including toe out gait, have been proposed as treatments for knee osteoarthritis. The clinical application of toe out gait, however, is unclear. This study aims to identify the changes in Knee adduction moment in varus knee deformity assessing toe out gait as an alternative to high tibial osteotomy, and if any change in dynamic loading persists post operatively, when anatomical alignment is restored.

Can mandibular bone resorption predict hip fracture in elderly women? A systematic review of diagnostic test accuracy.

Objectives: The aim of this systematic review was to determine the diagnostic accuracy of the mandibular cortical width measurements and porosity in detecting hip osteoporosis.

Background: All of the included studies used measurements on panoramic radiographs.

Materials And Methods: Studies were included if they compared the radiographic measurements (or index tests) with central dual energy X-ray absorptiometry (DXA) of the hip as the reference standard.

Acute endometrial bowel obstruction-A rare indication for colonic stenting.

Introduction: Pelvic endometriosis is an extremely rare cause of large bowel obstruction and the management can be challenging. Urgent surgery for acute colonic obstruction is known to carry high morbidity and mortality, and operation may be made more difficult in extensive pelvic endometriosis. Less invasive alternatives in the acute situation may need to be considered.

Influence of renal clearance on peripheral homovanillic acid measurements in healthy subjects and schizophrenic patients.

In order to investigate the effect of renal clearance on plasma homovanillic acid (HVA) concentrations, we examined plasma concentration and urinary excretion of HVA and creatinine per 4 h over 24 h in eight male schizophrenic patients and eight healthy male subjects. Renal clearances of HVA and of creatinine were determined per 4 h period. No significant differences were found between groups in the total 24 h excretion of either HVA or creatinine.

Determination of plasma homovanillic acid by liquid chromatography with electrochemical detection.

We describe a simple method for extracting homovanillic acid (HVA) from plasma. An aliquot of 0.5 ml of the internal standard solution (3-hydroxy-4-methoxycinnamic acid in 0.

Sleep, Epstein-Barr virus infection, musculoskeletal pain, and depressive symptoms in chronic fatigue syndrome.

Sleep physiology, viral serology and symptoms of 14 patients with chronic fatigue syndrome (CFS) were compared with 12 healthy controls. All patients described unrefreshing sleep and showed a prominent alpha electroencephalographic nonrapid eye movement (7.5-11.

Needs of well siblings of persons with schizophrenia.

The practical concerns of well siblings of persons with schizophrenia were examined in a descriptive study that included a needs assessment survey and a workshop designed to increase well siblings' knowledge about schizophrenia. A questionnaire focusing on needs for information, support, and practical skills was completed by 88 well siblings and 19 of their spouses. The results indicated a desire for more specific information about schizophrenia, particularly prognosis, and difficulties in communicating and problem solving with siblings with schizophrenia.

Developmental and neurologic correlates of treatment response in schizophrenia.

Reliable predictors of outcome in schizophrenia remain elusive, and assessment of unidimensional variables is unlikely to provide new information. We examined developmental, neurologic and psychosocial variables together to assess their correlation with several separate aspects of outcome in male schizophrenic patients (N = 31) treated with neuroleptics for a minimum of six months. Outcome measures evaluating social performance were significantly inter-correlated, but these measures did not correlate significantly with "positive" symptom measures.

Aberrant sialylation of granulocyte membranes in chronic myelogenous leukemia.

Peripheral blood granulocytes from patients with chronic myelogenous leukemia (CML) were studied for accessibility of membrane sialic acid and galactose residues to sodium borohydride-3H radiolabeling after oxidation with sodium metaperiodate (PI/B3H4) or with galactose oxidase (GO/B3H4). Granulocytes from untreated patients with chronic myelogenous leukemia showed increased radiolabeling with PI/B3H4, and decreased labeling with GO/B3H4 when compared to normal granulocytes. Granulocytes from leukemic patients receiving chemotherapy showed normal labeling patterns.
