A Case Report of Pneumococcal Septic Arthritis Following a Respiratory and Gastrointestinal Prodrome with Accompanying Literature Review

We report an uncommon case of septic arthritis of the ankle from a Streptococcus pneumoniae infection and provide an update of the literature reported since 2002. A 58-year-old female presented to the hospital with right ankle pain and an inability to bear weight. She reported a history of productive cough, vomiting, diarrhea, and subjective fevers 4 days earlier. Streptococcus pneumonia was identified in her ankle aspirate, and she was treated urgently with operative incision and debridement, followed by postoperative intravenous antibiotics. At her 7-week follow-up, she demonstrated complete resolution of symptoms and near-complete recovery of range of motion. This case demonstrates the importance of early identification, as the majority of patients recover fully with prompt treatment. The literature review included 44 cases of pneumococcal septic arthritis and found that the knee was the most commonly affected joint, followed by the shoulder and ankle. Blood cultures were positive for S. pneumoniae in 27 of 38 adults (71%) and 4 of 6 children (67%). Comorbid conditions were present in 32 of 38 adults (84%) and 4 of 7 children (57%), the most frequent of which were alcoholism and osteoarthritis in adults and malignancy or immunosuppression in children. Additionally, roughly half of included adults had an extra-articular focus of pneumococcal disease, most frequently pneumonia. Operative treatment was undertaken in 32 of 38 adults (84%) and all 7 children. Of adults with data available, 24 of 33 (73%) recovered with complete joint function, compared with 5 of 7 children (71%).

A systematic review of quality of reporting in registered intimate partner violence studies: where can we improve?

BACKGROUND

Reporting quality is paramount when presenting clinical findings in published research to ensure that we have the highest quality of evidence. Poorly reported clinical findings can result in a number of potential pitfalls, including confusion of the methodology used or selective reporting of study results. There are guidelines and checklists that aim to standardize the way in which studies are reported in the literature to ensure transparency. The use of these reporting guidelines may aid in the appropriate reporting of research, which is of increased importance in highly complex fields like intimate partner violence (IPV). The primary objective of this systematic review is to assess the reporting quality of published IPV studies using the CONSORT and STROBE checklists.

METHODS

We performed a systematic review of three large study registries for IPV studies. Of the completed studies, we sought full text publications and used reporting checklists to assess the quality of reporting.

RESULTS

Of the 42 randomized controlled trials, the mean score on the CONSORT checklist was 63.5% (23.5/37 items, SD 4.7 items). There were also 12 pilot trials in this systematic review, which scored a mean of 49.3% (19.7/40 items; SD 3.3 items) on the CONSORT extension for pilot trials. We included 12 observational studies which scored a mean of 56.1% (18.5/33 items; SD: 4.1 items).

CONCLUSIONS

We identified an opportunity to improve reporting quality by encouraging adherence to reporting guidelines. There should be a particular focus on ensuring that pilot studies report pilot-specific items. All researchers have a responsibility to ensure commitment to high quality reporting to ensure transparency in IPV studies.

Have the Annual Trends of Total Knee Arthroplasty in Rheumatoid Arthritis Patients Changed?

As the use of disease modifying antirheumatic drugs have increased, it remains unclear whether or not this has affected the rates of total knee arthroplasty (TKA) in rheumatoid arthritis (RA) patients. Therefore, the purpose of this study was to evaluate the annual trends of RA patients who underwent TKA. Specifically, we evaluated: (1) the annual trends of TKAs due to RA in the United States population; and (2) the annual trends in the proportion of TKAs due to RA in the United States. The Nationwide Inpatient Sample was used to identify all patients who underwent TKA between 2002 and 2013 (n = 6,492,873). Then, we identified TKA patients who had a diagnosis of RA, defined by the International Classification of Diseases, Ninth Revision (ICD-9) code 714.0. The incidence of TKAs with a diagnosis of RA in the United States was calculated using the U.S. population as the denominator. Regression models were used to analyze the annual trends of RA in patients who underwent TKA. A total of 209,332 RA patients were identified who underwent TKA. The annual prevalence of RA in patients who underwent TKA slightly increased, from 33.2 per 1,000 TKAs in 2002 to 35 per 1,000 TKAs in 2013 (R² = 0.254, p = 0.095). The annual number of TKAs with a diagnosis of RA increased by 93.1% from 11,618 to 22,430. After normalizing for the U.S. population, the incidence of TKAs with RA increased from 5.4 to 9.2 TKAs per 1 million U.S. adults (incidence rate ratio [IRR] = 1.05; 95% confidence interval [CI], 1.05-1.05; p < 0.001). In 2002, 11,618 (3.31%) TKAs, and in 2013, 22,430 (3.50%) TKAs were due to RA. The prevalence of RA in those who underwent TKA remained the same from 2002 to 2013 (coefficient = 0.02; 95% CI, -0.01 to 0.05; p = 0.095). The results of this study demonstrated that the rates of TKA performed in RA patients have remained relatively stable. Furthermore, there may have been a decline in the rate of RA patients undergoing TKA, due to an increase in the U.S. population by approximately 28.8 million during the study period.

Mechanical Prophylaxis after Lower Extremity Total Joint Arthroplasty: A Review

Venous thromboembolism (VTE) is a serious complication that can occur after total hip and knee arthroplasty, and can potentially lead to significant morbidity and even mortality. While various modalities have been used to prevent VTE development, the medications can be associated with a number of adverse events. Therefore, mechanical prophylaxis with pumps and compressive devices has been used more frequently alone, or in combination, with medications. Therefore, the purpose of this study was to review the current literature on mechanical prophylaxis for VTEs after lower extremity total joint arthroplasty. Specifically, we reviewed mechanical prophylaxis after: 1) total hip arthroplasty and 2) total knee arthroplasty.

Have the annual trends of total hip arthroplasty in rheumatoid arthritis patients decreased?

Background

Rheumatoid arthritis (RA) is characterized by chronic systemic and synovial inflammation, resulting in damage to both cartilage and bone. Medical treatment, which has increasingly relied upon disease modifying anti-rheumatic drugs (DMARDs), may fail to slow disease progression and limit joint damage, ultimately warranting surgical intervention. Up to 25% of RA patients will require lower extremity total joint arthroplasty. Though total hip arthroplasty (THA) is known to improve quality of life and functional measures, clarification is still required with respect to the impact of increased DMARD use on annual rates of THA. Thus, the purpose of this study was to evaluate: (I) the annual trends of THAs due to RA in the United States population; (II) the annual trends in the proportion of THAs due to RA in the United States.

Methods

This study utilized the Nationwide Inpatient Sample (NIS) to identify all patients who underwent THA between 2002 and 2013 (n=3,135,904). Then, THA patients who had a diagnosis of RA, which was defined by the International Classification of Disease 9^th revision diagnosis code 714.0, were identified. The incidence of THAs with a diagnosis of RA in the United States was calculated using the United States population as the denominator. Regression models were used to analyze the annual trends of RA in patients who underwent THA.

Results

Review of the database identified 90,487 patients who had a diagnosis of RA and underwent THA from 2002 to 2013. The annual prevalence of RA in those who underwent THA slightly decreased over the specified time period, with 28.7 per 1,000 THAs in 2002 and 28.6 per 1,000 THAs in 2013; however, this change was not statistically significant (R²=0.158, P=0.200).

Conclusions

The annual rates of THA among RA patients did not show any significant change between 2002 and 2013. DMARD use has decreased both disease progression and joint destruction, and DMARDs are now often utilized as primary treatment. The increase in population of the country during the study period may have overestimated THA trends. Moreover, patients may be more likely to opt for surgical management, given the advances in operative techniques as well as peri- and post-operative course.
