Methicillin-resistant coagulase-negative staphylococci (MRCoNS) are major nosocomial pathogens which cause device-related infections. Presence of various virulence factors along with methicillin resistance favor improved CoNS pathogenicity and their dissemination among population. In the present study, mec gene prevalence was analyzed along with SCC mec diversity among 55 human clinical CoNS isolates. PCR screening of insertion sequence (IS256) was also conducted to elucidate their association with methicillin resistance among selected CoNS species...

Aagje Swinnen, Kate de Medeiros
This paper is a humanities-based inquiry, applying Huizinga's framework of homo ludens ("man the player") to consider "play" in the context of two participatory arts programs (TimeSlips and the Alzheimer's Poetry Project) for people living with dementia. "Play," according to this Dutch historian, is at the heart of human activity and what gives meaning to life. Despite empirical research on play across the life course, play in dementia care is a relatively new idea. In addition, there is a dearth of reports based on humanistic inquiry which has slightly different goals than the growing body of qualitative and quantitative studies of participatory arts interventions...

INTRODUCTION: Laminectomy is the traditional approach for posterior exposure of the spinal canal for tumor resection. Another technique is split laminotomy, which entails the division and retraction of the spinous processes and laminae to access the thecal sac. This technique has been employed for small-segment exposures, but not extensively explored for long-segment exposures. CASE: A 2-month-old male presented with progressive right-leg plegia. MRI of the spine revealed a large, intramedullary spinal-cord lipoma extending from C6 to L5...

Gout is the most common cause of inflammatory arthritis in men over 40 [1]. The prevalence of gout in the US is approximately 3.9%. Tophus is a characteristic sign of gout and results when monosodium urate deposits at the joint, skin, or cartilage. Tophi develop in 12-35% of patients who are diagnosed with gout [2]. We report a case of a 70-year-old man who was diagnosed with squamous cell carcinoma of the helix via shave biopsy. During Mohs micrographic surgery, a vigorous foreign-body reaction was noted. Review of the initial biopsy slides identified crystals with pseudoepitheliomatous hyperplasia (PEH) rendering a diagnosis of gout...

Habit tic nail deformity is a nail dystrophy resulting from habitual, repetitive trauma to the nail. It is usually acquired in adulthood, however, we report a case of habit tic nail deformity in an 8 year old boy. The diagnosis was made clinically with further history revealing that the boy repeatedly rubbed his thumbnails and pushed the cuticles. Emollient cream (Balneum®) was recommended twice daily and both the patient and his mother were educated on the behavioral nature of this condition. There was marked improvement at 6 months of treatment and further improvement at 12 months...

Lawrence N Diebel, Jonathan V Martin, David M Liberati
BACKGROUND: Systemic vascular endothelial injury is a consequence of trauma-hemorrhagic shock (T/HS) which results in disturbances of coagulation, inflammation and endothelial barrier integrity. The effect of T/HS on the endothelium (Endotheliopathy of Trauma)[EoT] is of intense research interest and may lead to EoT directed therapies. Administration of tranexamic acid (TXA) in trauma patients is associated with a survival benefit and fewer complications if given early after injury. Mechanisms for this protective effect include the anti-fibrinolytic and anti-inflammatory effects of TXA...
