Staphylococcus aureus infections are associated with increased morbidity, mortality, hospital stay, and health care costs. S aureus colonization has been shown to increase risk for invasive and noninvasive infections. Decolonization of S aureus has been evaluated in multiple patient settings as a possible strategy to decrease the risk of S aureus transmission and infection. In this article, we review the recent literature on S aureus decolonization in surgical patients, patients with recurrent skin and soft tissue infections, critically ill patients, hospitalized non-critically ill patients, dialysis patients, and nursing home residents to inform clinical practice.Cellulitis is a common clinical diagnosis in the outpatient and inpatient setting; studies have demonstrated a surprisingly high misdiagnosis rate nearly one-third of cases are other conditions (ie, pseudocellulitis). This high rate of misdiagnosis is thought to contribute to nearly $515 million in avoidable health care spending in the United States each year; leading to the delayed or missed diagnosis of pseudocellulitis and to delays in appropriate treatment. There is a broad differential diagnosis for pseudocellulitis, which includes inflammatory and noninflammatory conditions of the skin. Accurate diagnosis of the specific condition causing pseudocellulitis is crucial to management, which varies greatly.Staphylococcus aureus is the most common bacteria causing purulent skin and soft tissue infections. Many disease-causing S aureus strains are methicillin resistant; thus, empiric therapy should be given to cover methicillin-resistant S aureus. Bacterial wound cultures are important for characterizing local susceptibility patterns. Definitive antibiotic therapy is warranted, although there are no compelling data demonstrating superiority of any one antibiotic over another. Antibiotic choice is predicated by the infection severity, local susceptibility patterns, and drug-related safety, tolerability, and cost. Response to therapy is expected within the first days; 5 to 7 days of therapy is typically adequate to achieve cure.
Distortion is an intrinsic phenomenon associated with image-intensified fluoroscopy that is both poorly understood and infrequently appreciated by orthopedic surgeons. Little information exists regarding its potential influence on intraoperative parameters during orthopedic surgery, letalone during direct anterior (DA) total hip arthroplasty (THA). The purpose of this study was to quantify the amount of potential error caused by fluoroscopic distortion during DA THA.
Intra-operative fluoroscopic pelvic images from 74 DA THAs were reviewed by two independent readers. All images were obtained using the same fluoroscopic C-arm unit with a radiopaque grid attached to the image intensifier. The vertical distortion from a straight central horizontal line at the peripheries of images were measured and summed to yield the combined vertical distortion similar to how a surgeon calculates a side to side comparison of limb lengths. Simple linear regression was used to evaluate associations between total distortion and patient demographics, operating theaters, and various operative parameters.
The average combined distortion was 10.0mm (range 2.0-20.0mm). There was a significant difference in the average distortion observed in different theaters (P < .001). There was no association between distortion and patient demographics or fluoroscopic time (all, P > .05).
Fluoroscopic distortion is unpredictable and can cause a substantial amount of error when comparing limb lengths during DA THA. This is a critical finding as this amount of inaccuracy could lead to unintended implant positioning and limb-length discrepancies if unaccounted for.

The aims of this study were to determine if increasing body mass index (BMI) is a risk factor for failure to attain the 1-year Patient Reported Outcomes Measurement Information System Physical Function (PROMIS PF-10a) minimal clinically important difference (MCID) following total joint arthroplasty (TJA) and to determine a possible BMI threshold beyond which this risk increases significantly.
This retrospective study was performed using 3506 TJAs sourced from a regional-based registry. An anchor-based MCID threshold of 7.9 was chosen. PROMIS PF-10a scores were collected at the preoperative and 1-year postoperative timepoints, and the change was used to determine failure to achieve the 1-year MCID. Demographic and surgical variables were also collected. The association between BMI and failure to achieve 1-year PROMIS PF-10 MCID was then evaluated using logistic regression. A BMI threshold was determined using receiver operating characteristic (ROC) curve analysis.
Increasing BMI assessed continuously was a significant risk factor for failure to achieve the MCID (P < .001). "Obese Class I" (30-35 kg/m
), "Obese Class II" (35-40 kg/m
), and "Obese Class III" (>40 kg/m
) subgroups compared to "Normal BMI" (<25 kg/m
) were significantly associated (P < .05) with this adverse outcome as well.
Our study showed that increasing BMI is a risk factor for failure to achieve the 1-year PROMIS PF-10a MCID following TJA. Among our patients, an increase in 1 kg/m
increased the risk of failure to achieve the MCID by 2%. With these findings, surgeons will be better equipped to preoperatively advise patients with elevated BMIs considering TJA.

The genus Cryptococcus comprises two major fungal species that cause clinical infections in humans Cryptococcus gattii and Cryptococcus neoformans. To establish invasive human disease, inhaled cryptococci must penetrate the lung tissue and reproduce. Each year, about 1 million cases of Cryptococcus infection are reported worldwide, and the infection's mortality rate ranges from 20% to 70%. Many HIV
/AIDS patients are affected by Cryptococcus infections, with 220,000 cases of cryptococcal meningitis reported worldwide in this population every year (C. neoformans infection statistics, via the Centers for Disease Control and Prevention, https//www.cdc.gov/fungal/diseases/cryptococcosis-neoformans/statistics.html). To escape from host immune cell attack, Cryptococcus covers itself in a sugar-based capsule composed primarily of glucuronoxylomannan (GXM). RIP kinase inhibitor To evade phagocytosis, yeast cells increase to a >45-µm perimeter and become titan, or giant, cells. Cryptococci virulence is directly proportional to the percentage of titan/giant cells present during Cryptococcus infection.
