An Unusual Case of Systemic Lupus Erythematosus and Hemophagocytic Syndrome.

Hemophagocytic syndrome (HS) or hemophagocytic lymphohistiocytosis (HLH) is an immune mediated phenomenon that can occur in the setting of an autoimmune disease, chronic immunosuppression, malignancy, or infection. It has been more commonly described in the pediatric population and less commonly in adults. We describe a case of a 52-year-old male who presented with a rash.

Negative Pressure Wound Therapy With Instillation: Review of Evidence and Recommendations.

Negative pressure wound therapy with instillation (NPWTi) and dwell time is an adjunctive treatment modality for selected complex wounds. Because of the greater amount of research now available, a multidisciplinary expert panel comprising the fields of podiatry, plastic and general surgery, burn treatment, infectious diseases, and orthopedics was convened on July 11, 2015, to produce a summary of the data and recommendations on the use of NPWTi. The panel members each reviewed available published literature on NPWTi in the PubMed, Cochrane, and Google Scholar databases from 1 January 2012 up until 20 July 2015 using the string search term negative pressure wound therapy instillation provided by the panel moderator; there were no restrictions on the language or type of publication.

Granulomatous Interstitial Nephritis Presenting as Hypercalcemia and Nephrolithiasis.

We report a case of acute kidney injury as the initial manifestation of sarcoidosis. A 55-year-old male was sent from his primary care physician's office with incidental lab findings significant for hypercalcemia and acute kidney injury with past medical history significant for nephrolithiasis. Initial treatment with intravenous hydration did not improve his condition.

Genomic instability in pancreatic adenocarcinoma: a new step towards precision medicine and novel therapeutic approaches.

Pancreatic cancer is one of the most challenging cancers. Whole genome sequencing studies have been conducted to elucidate the underlying fundamentals underscoring disease behavior. Studies have identified a subgroup of pancreatic cancer patients with distinct molecular and clinical features.

Role of Vorapaxar After Coronary Revascularization.

We aim to evaluate the potential benefit and risk of addition of vorapaxar to standard medical therapy in patients who underwent coronary revascularization with either percutaneous coronary revascularization or coronary artery bypass graft surgery. We searched PubMed, EMBASE, the Cochrane Central Register of Controlled trials, and the clinical trial registry maintained at clinicaltrials.gov for randomized control trials evaluating the safety and efficacy of vorapaxar in patients who underwent coronary revascularization procedures with either percutaneous coronary revascularization or coronary artery bypass graft surgery.

Phase angle and its determinants in healthy subjects: influence of body composition.

Background: The phase angle (PA) has been used as a prognostic marker in several clinical situations. Nevertheless, its biological meaning is not completely understood.

Objective: We verified how body-composition components could explain the PA.

Cytokine preconditioning of engineered cartilage provides protection against interleukin-1 insult.

Background: During osteoarthritis and following surgical procedures, the environment of the knee is rich in proinflammatory cytokines such as IL-1. Introduction of tissue-engineered cartilage constructs to a chemically harsh milieu may limit the functionality of the implanted tissue over long periods. A chemical preconditioning scheme (application of low doses of IL-1) was tested as a method to prepare developing engineered tissue to withstand exposure to a higher concentration of the cytokine, known to elicit proteolysis as well as rapid degeneration of cartilage.

Computed tomography findings of internal hernia after gastric bypass that may precede small bowel obstruction.

Purpose: This study evaluates computed tomography signs of internal hernia in gastric bypass patients, including several previously unreported signs suggestive of internal hernia.

Methods: Eighteen patients with surgically proven internal hernia were included in the study cohort. The signs analyzed included the mesenteric swirl, hurricane eye, mushroom sign, and dilated small bowel loops, as well as previously non-investigated signs such as bowel wall edema, engorged mesenteric vessels, engorged mesenteric lymph nodes, and hazy mesenteric fat.

Predictors and Survival Impact of False-Negative Sentinel Nodes in Melanoma.

Background: The status of the sentinel lymph node in melanoma is an important prognostic factor. The clinical predictors and implications of false-negative (FN) biopsy remain debatable.

Methods: We compared patients with positive sentinel lymph node biopsy (SNB) [true positive (TP)] and negative SNB with and without regional recurrence [FN, true negative (TN)] from our prospective institutional database.

The State of Evaluation Research on Food Policies to Reduce Obesity and Diabetes Among Adults in the United States, 2000-2011.

Introduction: Improvements in diet can prevent obesity and type 2 diabetes. Although policy changes provide a foundation for improvement at the population level, evidence for the effectiveness of such changes is slim. This study summarizes the literature on recent efforts in the United States to change food-related policies to prevent obesity and diabetes among adults.

An updated h-index measures both the primary and total scientific output of a researcher.

The growing interest in scientometry stems from ethical concerns related to the proper evaluation of scientific contributions of an author working in a hard science. In the absence of a consensus, institutions may use arbitrary methods for evaluating scientists for employment and promotion. There are several indices in use that attempt to establish the most appropriate and suggestive position of any scientist in the field he/she works in.

Challenges in the successful management of a case of acute intermittent porphyria in India.

Acute intermittent porphyria (AIP) is a rare metabolic disease involving a defect in haem biosynthesis resulting in the accumulation and excessive secretion of porphyrins and its precursors. Acute attacks present with episodes of severe abdominal pain, nausea, confusion and severe life-threatening seizures. A high index of suspicion is required for the initial diagnosis of AIP.

Myelomatous Pleural Effusion Presenting with Extreme Hyperferritinemia and Severe Inflammatory Response.

Myelomatous involvement of pleural effusions developing in patients with multiple myeloma is extremely rare and only a few cases have been reported so far. It is thought to represent an aggressive clinical progression of disease and is usually associated with severe complications, poor prognosis and high mortality. Ferritin is a marker of inflammatory pathways that plays a significant role in plasma cell malignancies and has been studied as a prognostic factor for multiple myeloma.

Dysphagia and Neck Swelling in a Case of Undiagnosed Lhermitte-Duclos Disease and Cowden Syndrome.

We report a case of a 37-year-old woman presenting with dysphagia and thyroid masses who was subsequently diagnosed with Lhermitte-Duclos disease (LDD) based on MRI scan and histopathology. Additional imaging subsequently revealed the presence of thyroid nodules and bilateral breast cancers. Genetic testing later confirmed the diagnosis of Cowden syndrome.

Molecular signature of pancreatic adenocarcinoma: an insight from genotype to phenotype and challenges for targeted therapy.

Introduction: Pancreatic adenocarcinoma remains one of the most clinically challenging cancers despite an in-depth characterization of the molecular underpinnings and biology of this disease. Recent whole-genome-wide studies have elucidated the diverse and complex genetic alterations which generate a unique oncogenic signature for an individual pancreatic cancer patient and which may explain diverse disease behavior in a clinical setting.

Areas Covered: In this review article, we discuss the key oncogenic pathways of pancreatic cancer including RAS-MAPK, PI3KCA and TGF-β signaling, as well as the impact of these pathways on the disease behavior and their potential targetability.
