Causation Analysis

Abstract Meniscal tears and osteoarthritis (osteoarthrosis, degenerative arthritis, or degenerative joint disease) are two of the most common conditions involving the knee. This article includes definitions of apportionment and causes; presents a case report of initial and recurrent tears of the medial meniscus plus osteoarthritis (OA) in the medial compartment of the knee; and addresses questions regarding apportionment. The authors, experienced impairment raters who are knowledgeable regarding the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), show that, when instructions on impairment rating are incomplete, unclear, or inconsistent, interrater reliability diminishes (different physicians may derive different impairment estimates). Accurate apportionment of impairment is a demanding task that requires detailed knowledge of causation for the conditions in question; the mechanisms of injury or extent of exposures; prior and current symptoms, functional status, physical findings, and clinical study results; and use of the appropriate edition of the AMA Guides. Sometimes the available data are incomplete, requiring the rating physician to make assumptions. However, if those assumptions are reasonable and consistent with the medical literature and facts of the case, if the causation analysis is plausible, and if the examiner follows impairment rating instructions in the AMA Guides (or at least uses a rational and hence defensible method when instructions are suboptimal), the resulting apportionment should be credible.

A Prospective Study

SummaryTwenty-four dogs (27 limbs) were evaluated after surgery for correction of forelimb angular limb deformities. Partial ulnar ostectomies or definitive corrective osteotomies were performed depending upon the age of the dog. According to owner assessment nine of fourteen limbs were considered functionally good, or excellent, after partial ulnar ostectomies. Younger dogs appeared to have better functional results after dynamic correction with the mean age at surgery of dogs with good to excellent results being 6.5 months contrasted to the mean age at surgery of dogs with fair to poor results being 9.75 months. Ten of fourteen limbs were considered functionally good or excellent after definitive corrective osteotomy. One dog had definitive osteotomy after partial ulnar ostectomy in order to further correct a residual angular deformity. However, 58% of the limbs with radiographic follow-up had signs of degenerative joint disease (DJD). There were not significant differences between neither degree of angulation remaining after surgery and the functional result nor the degree of angulation remaining after surgery and the development of DJD. A prospective study is warranted to more objectively assess the efficacy of surgical correction of angular limb deformities in dogs.Twenty-four dogs were evaluated after surgery for correction of forelimb angular limb deformities. The results are described.

SummaryThree mucopolysaccharides (MPS) used in the treatment of degenerative joint disease were compared to heparin to establish their relative potencies on 3 coagulation tests, the aPTT, the antifactor X a activity and the dilute thrombin time. One of the compounds, Arteparon®, was one fourth as potent as heparin on the aPTT, but had little or no influence on the 2 other tests. Further in vitro studies suggested that Arteparon® acted at a higher level than factor Xa generation in the intrinsic amplification system and that its effect was independent of antithrombin III. In vivo administration of Arteparon® confirmed its anticoagulant properties, which raises the question of the clinical use of this MPS.

Gut Microbiota Composition

Osteoarthritis is a most widespread chronic degenerative joint disease that causes pain, cartilage deformation, and joint inflammation. Adverse alterations of intestinal microbiota like dysbiosis may lead to metabolic syndrome and inflammation, two important components of osteoarthritis progression. Aim. In this study we investigated the effect of chondroitin sulfate and probiotics on the gut microbiome in monoiodoacetate-induced osteoarthritis model in rats. Methods. The species and quantitative composition of feces were determined using diagnostic media with selective properties. Further identification of isolated microorganisms was carried out according to morphological, tinctorial, physiological and metabolic parameters. The results are presented in the form of lg CFU/g. Results. Induction of osteoarthritis caused significant increasing the number of opportunistic enterobacteria and lactose-negative Escherichia coli against the decreasing of lacto- and bifidobacteria that may indicate a dysbiotic condition. Coadministration of chondroitin sulfate and probiotic bacteria has led to improvement the quantitative composition of the gut microbiota in experimental animals, the numerous of Bifidobacterium, Lactobacillus were increasing against decreasing the quantitative composition of opportunistic microorganisms. Conclusions. Monoiodoacetate-induced osteoarthritis caused dysbiosis of gut in rat. We observed beneficial effect of combined administration of chondroitin sulfate and probiotics on gut microbiota composition in rats with experimental osteoarthritis. Thus, adding of supplements like probiotics to standard treatment of osteoarthritis may have potentials to prevent and treat this disease.

Abstract. Introduction: Calcium pyrophosphate deposition disease (CPPD), or pseudogout, is rare in prosthetic joints, but can mimic prosthetic joint infection (PJI) according to case reports. The purpose of this case series is to describe the demographics, presentation, management, and outcomes of a cohort of these patients seen at our academic medical center.Methods: Patients with post-implant pseudogout, who were evaluated at our medical center between January 1, 2000 and June 30, 2016, were identified from our EHR. Data pertaining to demographics, presentation, management, and outcomes were abstracted, and patients were categorized into two groups based on presence of concomitant infection along with positive CPDD findings in synovial fluid.Results: 22 patients were included. 90.9% of cases involved a TKA. The most common indication for arthroplasty was degenerative joint disease. Only four patients had a history of previous gout or pseudogout, three of which belonged to the group with no evidence of concomitant joint infection. Clinical features for patients without concomitant infection included pain (100%), swelling at the joint (88.9%), redness (33.3%), fever (22.2%), and decreased range of motion (100%). 45.5% of patients received antibiotics prior to joint aspiration (44.4% of patients with negative synovial fluid cultures, 46.2% of patients with concomitant infection).Conclusion: Our study suggests similar clinical presentation between post-implant pseudogout and PJI. Among patients with pseudogout as well as in those with PJI, the first dose of antibiotics should not be given before sampling for synovial culture. Unfortunately, many patients receive antibiotics prior to culture ascertainment, which raises concern for antibiotic overuse.
