INTRODUCTION: Short stem femoral components in primary total hip arthroplasty (THA) have increased in popularity since the advent of minimally invasive surgical techniques. The concept of a short stem is particularly compatible with tapered designs where the goal is to offload forces proximally in the femur. The purpose of this retrospective review was to review our early experience with a short, tapered titanium femoral component with updated design features. MATERIALS AND METHODS: Beginning in November 2011 through February 2012, 92 consented patients (93 hips), at a single center, were treated with primary cementless THA using a short stem, tapered femoral component (Taperloc® Complete Microplasty; Zimmer Biomet, Warsaw, Indiana) and were available for review with a minimum two-year follow-up...

INTRODUCTION: Periprosthetic joint infection (PJI) following primary total knee arthroplasty (TKA) is a challenging complication for surgeons and patients alike. Although two-stage revision arthroplasty remains the gold standard PJI management in the United States, one-stage revision has had success in many parts of Europe. The aim of this study was to retrospectively review: 1) ultimate treatment success; 2) necessary antibiotic duration; 3) change in knee range of motion (ROM); and 4) final Knee Society Scores (KSS) in a case series of patients managed with retention of articulating antibiotic spacers following PJI...

BACKGROUND: Dislocation is one of the most common complications after revision THA. Dual-mobility constructs and large femoral heads (ie, 40 mm) are two contemporary, nonconstrained bearing options used in revision THA to minimize the risk of dislocation; however, it is not currently established if there is a clear benefit to using dual-mobility constructs over large femoral heads in the revision setting. QUESTIONS/PURPOSES: We sought to determine if dual-mobility constructs would provide a reduction in dislocation, rerevision for dislocation, and reoperation or other complications as compared with large femoral heads in revision THA...

In patients who have undergone a colonic resection with creation of an end colostomy, drainage of mucus secreted by the mucosa of the rectal stump may not be possible if there is an outlet obstruction. With an outlet obstruction, formation of a rectal mucocele occurs. A rectal mucocele is a rare condition which has only been reported sporadically in case reports. We present here the utility of an intersphincteric proctectomy for treatment of a rectal mucocele in a 47 year old male Crohn's patient resulting in negligible post-operative or long-term morbidities...

Attachment theory is an important framework from which to examine familial aged care. Despite this, the role of attachment in later-life caregiving remains unclear. The current study presents a systematic review of papers within the last five years on attachment and various outcomes related to familial aged care. For the caregiver, attachment anxiety was associated with poorer mental health, and attachment insecurity with a more controlling manner of caregiving. The few studies conducted with care recipients found that attachment insecurity was associated with greater self-appraisals of dementia symptoms and a lower sense of security...

In the past few years, there has been a significant effort by the forensic science community to develop new scientific techniques for the analysis of forensic evidence. Forensic chemists have been spearheaded to develop information-rich confirmatory technologies and techniques and apply them to a broad array of forensic challenges. The purpose of these confirmatory techniques is to provide alternatives to presumptive techniques that rely on data such as color changes, pattern matching, or retention time alone, which are prone to more false positives...

A unique materials' methodology enables the doping of metals with functional molecules, polymers, enzymes, and nanoparticles. The resulting materials have either the combined properties of the metal and the dopants, or new, sometimes synergetic properties that are not found in the separate components, emerge. Metals that have been doped so far include gold, silver, copper, iron, gallium, palladium, platinum, and several alloys. Numerous applications have been demonstrated including catalysis, biocatalysis, bioactivity, electrochemistry (including new type of batteries), corrosion resistance, induction of chirality, tailoring unconventional properties to metals, and more...

BACKGROUND: Early enteral nutrition has been shown to decrease complications and improve patient outcomes. Post pyloric feeding is recommended for patients with gastric intolerance or at high risk for aspiration. Feeding tube placement can be challenging and pose risk of pulmonary complications. Reliance on radiographic confirmation for feeding tube placement exposes the patient to radiation. Electromagnetic placement device (EMPD) may offer a method to minimize pulmonary complications, increase successful placement, and decrease radiation exposure to the patient...

Inflammatory bowel disease (IBD), including ulcerative colitis and Crohn's disease, is a chronic and unpredictable characterized by alternating periods of remission interspersed with relapses. In recent years accumulating support for an immunomodulating effect of vitamin D on both the innate and adaptive immune system has been presented. Through the vitamin D receptor, the active form of vitamin D, 1,25(OH)2D, induces antimicrobial peptide secretion, decrease dendritic cell activity, and promotes Th2 and regulatory T cell development and activity...

Advances in the methods for detecting protein-DNA interactions have played a key role in determining the directions of research into the mechanisms of transcriptional regulation. The most recent major technological transformation happened a decade ago, with the move from using tiling arrays [chromatin immunoprecipitation (ChIP)-on-Chip] to high-throughput sequencing (ChIP-seq) as a readout for ChIP assays. In addition to the numerous other ways in which it is superior to arrays, by eliminating the need to design and manufacture them, sequencing also opened the door to carrying out comparative analyses of genome-wide transcription factor occupancy across species and studying chromatin biology in previously less accessible model and nonmodel organisms, thus allowing us to understand the evolution and diversity of regulatory mechanisms in unprecedented detail...

Dermoscopy, commonly used to analyze skin tumors, has more recently been used to evaluate inflammatory dermatoses. We performed a systematic review of the literature to assess the role of dermoscopy in evaluating psoriasis, and briefly reviewed the findings with an emphasis on the specificity or sensitivity of the dermoscopic findings of psoriasis. We also describe the case of a 63-year-old man with a history of psoriasis and basal cell carcinoma (BCC) who presented with a new scaly pink patch on the back. This case highlights the importance of dermoscopy in differentiating patches and plaques of psoriasis from BCC...

The formation of the atherosclerotic plaque that is characterized by the accumulation of abnormal amounts of cholesterol-loaded macrophages in the artery wall is mediated by both inflammatory events and alterations of lipid/lipoprotein metabolism. Reverse transport of cholesterol (RCT) opposes the formation and development of atherosclerotic plaque through high density lipoprotein (HDL) metabolism, promoting the removal of cholesterol from peripheral macrophages and its delivery back to the liver for excretion into the bile...
