Actinomycosis complicating sigmoid diverticular disease: a case report
A 63-year-old Caucasian woman was admitted to hospital as hypotensive with abdominal tenderness and vaginal discharge. Laboratory investigations showed microcytic anaemia, low albumin and high white cell count. Computerised tomography scans revealed small bowel dilatation, sigmoid diverticula, ascites and pelvic fluid. The endometrial pipelle was positive and vaginal swab was negative for actinomyces. Post mortem examination revealed widespread sigmoid diverticular disease and bowel perforation with an intense inflammation. Actinomycotic granules were noted in the diverticular inflammatory debris, pelvic abscess and lung sections. Clinical course and histomorphological findings favour the perforating sigmoid diverticular actinomycosis as an origin of the systemic infection
Survivorship and risk factors for revision of metal-on-metal hip resurfacing: a long-term follow-up study
Aims: Metal-on-metal hip resurfacing (MoM-HR) has seen decreased usage due to safety and longevity concerns. Joint registries have highlighted the risks in females, smaller hips, and hip dysplasia. This study aimed to identify if reported risk factors are linked to revision in a long-term follow-up of MoM-HR performed by a non-designer surgeon. Methods: A retrospective review of consecutive MoM hip arthroplasties (MoM-HRAs) using Birmingham Hip Resurfacing was conducted. Data on procedure side, indication, implant sizes and orientation, highest blood cobalt and chromium ion concentrations, and all-cause revision were collected from local and UK National Joint Registry records. Results: A total of 243 hips (205 patients (163 male, 80 female; mean age at surgery 55.3 years (range 25.7 to 75.3)) with MoM-HRA performed between April 2003 and October 2020 were included. Mean follow-up was 11.2 years (range 0.3 to 17.8). Osteoarthritis was the most common indication (93.8%), and 13 hips (5.3%; 7M:6F) showed dysplasia (lateral centre-edge angle < 25°). Acetabular cups were implanted at a median of 45.4° abduction (interquartile range 41.9° - 48.3°) and stems neutral or valgus to the native neck-shaft angle. In all, 11 hips (4.5%; one male, ten females) in ten patients underwent revision surgery at a mean of 7.4 years (range 2.8 to 14.2), giving a cumulative survival rate of 94.8% (95% confidence interval (CI) 91.6% to 98.0%) at ten years, and 93.4% (95% CI 89.3% to 97.6%) at 17 years. For aseptic revision, male survivorship was 100% at 17 years, and 89.6% (95% CI 83.1% to 96.7%) at ten and 17 years for females. Increased metal ion levels were implicated in 50% of female revisions, with the remaining being revised for unexplained pain or avascular necrosis. Conclusion: The Birmingham MoM-HR showed 100% survivorship in males, exceeding the National Institute for Health and Care Excellence â5% at ten yearsâ threshold. Female sex and small component sizes are independent risk factors. Dysplasia alone is not a contraindication to resurfacing. Cite this article: Bone Jt Open 2023;4(11):853â858
The possible clinical predictors of fatigue in Parkinson's disease:a study of 135 patients as part of international nonmotor scale validation project
Fatigue is a common yet poorly understood and underresearched nonmotor symptom in Parkinsonâs disease. Although fatigue is recognized to significantly affect health-related quality of life, it remains underrecognised and empirically treated. In this paper, the prevalence of fatigue as measured by a validated visual analogue scale and the Parkinsonâs disease nonmotor symptoms scale (PDNMSS) was correlated with other motor and nonmotor comorbidities. In a cohort of patients from a range of disease stages, occurrence of fatigue correlated closely with more advanced Parkinsonâs disease, as well as with depression, anxiety, and sleep disorders, hinting at a common underlying basis
