Update on elbow arthroplasties with emphasis on imaging.

Elbow arthroplasty is increasing in popularity and can be used to treat many conditions, such as trauma, primary and secondary osteoarthritis, inflammatory arthritis, and osteonecrosis. Total elbow arthroplasty (TEA) is reserved for patients with severe symptoms refractory to more conservative management. In addition to TEA, hemi-arthroplasty, interposition arthroplasty, and resection arthroplasty also play roles in the management of elbow pain. There are specific indications for each type of arthroplasty. Postoperative complications may occur with elbow arthroplasties and may be surgery or hardware related. Imaging is important in both pre-operative planning as well as in post-surgical follow-up. This article reviews the different types of elbow arthroplasties, their indications, their normal postoperative imaging appearances, and imaging findings of potential complications.

Poor Medication Adherence in African Americans Is a Matter of Trust.

The purpose of this paper was to explore the lack of medication adherence in the African American patient community. The paper will address myths that many African American patients believe related to type 2 diabetes, hypertension treatment, and natural remedies. Research has shown that the disparities in the acceptance of healthcare provider advice and prescriptions are a significant concern particularly in African American patients. The acceptance of a provider's diagnosis and subsequent intervention can vary based on several issues including healthcare access, patient preferences, trust of a provider, and treatment recommendations. Patient influences can range from their ability to trust the provider (and what he/she says) to following through with their advice. Several studies have looked at the beliefs and misconceptions some African Americans hold regarding the treatment of hypertension and diabetes with some showing a preference for "natural remedies." This paper will leverage a literature review to seek out myths from African American patients to understand why they are dealing with challenges related to adherence with medication. The searches identified 58 research papers. The study applied an inductive content analysis approach to assess the research papers and identify themes. The barriers identified in this study include disbelief of the diagnosis, distrust for medication, mistrust for physicians and healthcare system, belief in alternative medicine, cultural/generation norms, and access/affordability of care. One of the most prominent factors that crossed all barriers was medical mistrust.

Aspergillus osteomyelitis of the proximal humerus: a case report.

Aspergillus osteomyelitis is an extremely rare manifestation of invasive aspergillosis. Generally, patients in states of significant immune deficiency are very susceptible to invasive aspergillosis. We report a case of Aspergillus osteomyelitis of the proximal humerus in an immunocompetent patient that required aggressive oral antifungal therapy, surgical debridement, and placement of an antifungal-impregnated cement spacer. Subsequently, her shoulder was reconstructed using a reverse total shoulder prosthesis The clinical course, radiographic findings, histology, and management rationale are presented.

Analysis of methoxyfenozide residues in fruits, vegetables, and mint by liquid chromatography-tandem mass spectrometry (LC-MS/MS).

Methoxyfenozide [3-methoxy-2-methylbenzoic acid 2-(3,5-dimethylbenzoyl)-2-(1,1-dimethylethyl) hydrazide; RH-2485], in the formulation of INTREPID, was applied to various crops. Analysis of methoxyfenozide was accomplished by utilizing liquid-liquid extraction and partitioning, followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Method validations for fruits, vegetables, and mint are reported. Methoxyfenozide mean recoveries ranged from 72 to 129% over three levels of fortification. The overall average of mean recoveries is 97 +/- 10%. The limit of quantitation for fruits, artichoke, cucumber, squash, and refined sugar was 0.010 ppm, with a detection limit of 0.005 ppm. For all other crops, the limit of quantitation was 0.050 ppm, with a detection limit of 0.025 ppm. No residues were found greater than the limit of quantitation in control samples. Residues above the limit of quantitation were found in all matrices except refined sugar. Foliage (bean, beet, pea, and radish) had greater residue levels of methoxyfenozide residue than their corresponding roots or pods. Other crop matrices contained <1.0 ppm of methoxyfenozide except artichoke, which had a mean of 1.10 ppm.
