Studies with complete exposure histories indicate skin lesions are associated with arsenic exposure in excess of 50 µg/L or higher.
Current studies are inadequate to conduct meta-analysis on dose-response relationship between exposure to arsenic in drinking water and skin lesions. Studies with complete exposure histories indicate skin lesions are associated with arsenic exposure in excess of 50 µg/L or higher.[This corrects the article on p. 191 in vol. 40, PMID 32754006.].[This corrects the article on p. 105 in vol. 40, PMID 32742216.].
Combined hip arthroscopy and periacetabular osteotomy (PAO) allows for treatment of intra-articular hip pathology with simultaneous correction of acetabular version and femoral head coverage in patients with symptomatic hip dysplasia. Currently, scant data is available to surgeons regarding optimal technique, sequence of repair, perioperative management, and the use of intra-abdominal monitoring in patients undergoing these combined procedures. The purpose of this study is to describe a two-surgeon, muscle-sparing, approach for sequential hip arthroscopy and PAO for the treatment of adults with acetabular dysplasia and concomitant intra-articular hip pathology.

In this article, we present the indications for combined hip arthroscopy and PAO, in addition to patient set-up and positioning. A detailed discussion of hip arthroscopy and a muscle sparing PAO techniques are then presented, with overview of a novel intra-abdominal pressure monitoring technique and post-operative rehabilitation protocol.

Throughn approach in hip preservation surgery. The hip arthroscopy and muscle-sparing PAO protocol using intra-abdominal monitoring described here serves to further refine and advance the indications and technical aspects of this challenging procedure.Level of Evidence V.
Orthopaedic surgeons remain the third-highest group of opioid prescribers among physicians in the United States, accounting for 8% of all opioid prescriptions. The purpose of this study was to identify risk factors for opioid consumption and opioid prescription refills after patellofemoral stabilization surgery. We hypothesized that preoperative opioid use and younger age would be independent risk factors for postoperative opioid use.

Patients undergoing primary patellar stabilization surgery between 2007-2017 in the Humana Inc. administrative claims database were identified using Current Procedural Terminology (CPT) codes for patellofemoral stabilization procedures (CPT-27420, 27422, 27427,27418). Patients were categorized into opioid naive (N-OU) and those who filled opioid prescriptions within 3 months prior to surgery (OU). Patients in the OU cohort were further categorized into those who filled prescriptions at 1-3 months before surgery (C-OU) and those who filled opioid prescriptions only in the monII.
Meniscal tears, specifically lateral meniscal tears, have a larger than expected un-derdiagnosis rate in the presence of an ACL tear. The purpose of our study was to search for an MRI bone contusion pattern associated with MRI occult meniscal tears in patients with an ACL tear, specifically a contusion of the rim of the medial femoral condyle (RMFC). Our hypothesis was that there would be a significant association between RMFC contusions and MRI occult meniscal tears in patients with an ACL tear. We also searched for a difference between sexes with respect to the presence of the RMFC contusion in the setting of an occult meniscal tear. We also categorized the type, size, and location of these occult meniscal tears in the setting of an ACL tear.

This was a retrospective study that examined characteristics of occult meniscal tears and their association with a RMFC bone contusion. IRB approval was obtained. The date range of the study was June 2009 through December 2015. https://www.selleckchem.com/products/coelenterazine.html 6392 consecutive knee MRI reports in itudinal tears). RMFC contusions were reliably identified by radiologists in this study.Level of Evidence II.
Open reduction and internal fixation (ORIF) of proximal humerus fractures in elderly individuals (age >70) carries a relatively high short-term complication and reoperation rate but is generally durable once healed. Reverse total shoulder arthroplasty (RTSA) for fractures may be associated with superior short-term quality of life but carries the lifelong liabilities of joint replacement. The tradeoff between short and long-term risks, coupled with disparities in quality of life and cost, makes this clinical decision amenable to cost-effectiveness analysis.

A Markov state-transition model was constructed with a base case of a 75 year-old patient. Reoperation rates, quality of life values, mortality rates, and costs were based upon published literature. The model was run until all patients had died to simulate the accumulated costs and benefits.

RTSA was associated with greater quality of life (7.11 QALYs) than ORIF (6.22 QALYs). RTSA was cost-effective with an incremental cost-effectiveness ratio of $3,945/QALY and $27,299/ QALY from payor and hospital perspectives, respectively. RTSA was favored and cost-effective at any age above 65 and any Charlson Score. The model was sensitive to the utility of both procedures.

RTSA resulted in a higher quality of life and was cost-effective in comparison to ORIF for elderly patients.

Pediatric buckle fractures of the wrist can be safely managed in 'minimalist' fashion with splinting and limited follow-up; however, traditional means of treatment remain prevalent. The purpose of this study was to 1) evaluate preferences for buckle fracture management among providers at a single institution and 2) identify factors influencing clinical decision-making and barriers to implementation of minimalist practices.

A 13 question survey was developed split into three sections 1) Demographics, 2) Preferred management, and 3) Influential factors. The survey was distributed to 32 providers within our hospital system involved in buckle fracture management via email over a 1 year period. Descriptive statistics of responses were performed to address study aims.

The survey participation rate was 72%. Respondents had 12.2+/-12.5 (Range 1-41) years of experience. Casting of buckle fractures was preferred by 56.5% of providers. Most (77%) were aware of literature supporting minimalist strategies. Family preferences (59.
