Between 1940 and 2004, more than 335 emerging infectious disease events were reported in the scientific literature. The majority (60%) of these events involved zoonoses, most of which (72%) were of wildlife origin or had an epidemiologically important wildlife host. Because this trend of increasing emerging diseases likely will continue, understanding the pathogenesis, transmission, and diagnosis of these diseases in the relevant wildlife host is paramount. Achieving this goal often requires using wild animals as research subjects, which are vastly different from the traditional livestock or laboratory animals used by most universities and institutions...

BACKGROUND: The incidence of invasive cancer within a mucinous cystic neoplasm of the pancreas varies between 6 and 36%. Polycystic ovarian syndrome is a disorder characterized by hyperandrogenism and anovulatory infertility. One surgical treatment that can restore endocrine balance and ovulation in polycystic ovarian syndrome is partial ovarian destruction. Successful pregnancies following preconception pancreaticoduodenectomies (Whipple procedures) and chemoradiation to treat pancreatic neoplasms have been reported rarely but none were diagnosed with pre-cancer polycystic ovarian syndrome-associated infertility...

Whipple's disease (WD) is a rare chronic systemic infection with a wide range of clinical symptoms, routinely diagnosed in biopsies from the small intestine and other tissues by periodic acid-Schiff (PAS) diastase staining and immunohistological analysis with specific antibodies. The aim of our study was to improve the pathological diagnosis of WD. Therefore, we analyzed the potential of fluorescence in situ hybridization (FISH) for diagnosing WD, using a Tropheryma (T.) whipplei-specific probe. 19 formalin-fixed paraffin-embedded (FFPE) duodenal biopsy specimens of 12 patients with treated (6/12) and untreated (6/12) WD were retrospectively examined using PAS diastase staining, immunohistochemistry, and FISH...

Detecting Whipple's disease, a "great imitator", requires a high index of suspicion so that antimicrobial treatment can be initiated in a timely manner; a missed diagnosis can be fatal. Although an uncommon cause, Whipple's disease must be considered in adults with mesenteric lymphadenitis. We report the case of a 39-year-old African American man who presented with chronic joint pain, chronic weight loss, and acute onset epigastric pain. Contrast-enhanced computed tomography of the abdomen and pelvis showed extensive mesenteric lymphadenopathy...

BACKGROUND: Solid pseudopapillary tumors (SPTs) of the pancreas are a rare occurrence, not exceeding 1-2% of all exocrine pancreatic tumors. SPT was first described in 1959 as "papillary tumor of the pancreas, benign or malignant" and affects mainly young women, in their second or third decade of age. These tumors are of low malignant potential, unclear pathogenesis, grow gradually and become considerably large before causing symptoms. A typical clinical presentation is often described by affected patients and, in some cases, an SPT is an incidental finding during the time the patient undergoes medical imaging studies for other health issues...

Introduction Carcinomas of the papilla of Vater make up a heterogeneous group of tumours arising from different types of epithelium. Regional lymph nodes, liver and lungs are the primary sites of metastatic progression of these tumours. Case presentation We present a patient with an abdominal incision site metastasis of low-grade (mixed type) adenocarcinoma of the papilla of Vater one year after pylorus-preserving pancreaticoduodenectomy. Implantation metastasis of low-grade ampullary carcinoma in the laparotomy wound after open Whipple's procedure is unusual...

The impact of stimulus size and presentation on choice during a preference assessment was investigated using a modified multiple-stimulus without replacement (MSWO) technique. Stimuli were either presented with a uniform magnitude, as determined by mass, or in a manner consistent with caregiver report of reinforcer consumption. While both assessment procedures identified the same top three preferred items in three out of five cases, greater variability in the preference rank of less preferred items was observed between assessments...

A male patient with obstructive jaundice was found to have an incidental nodule within the inferior vena cava (IVC), below the level of the renal vein, on abdominal imaging. At the time of the Whipple's procedure for pancreatic adenocarcinoma, the IVC mass measuring 3.4×2.7×2.2 cm was also removed. Histologically, the lesion was well circumscribed, composed focally of spindle-shaped cells with cigar-shaped nuclei reminiscent of smooth muscle and a dominant pervasive, pleomorphic, bizarre giant cell component...

A fast UHPLC-UV method was developed for the simultaneous analysis of Hydroxychloroquine, Minocycline and Doxycycline drugs from 100μL of human serum samples. Serum samples were extracted by liquid-liquid extraction and injected into a phenyl hexyl reverse phase column. Compounds were separated using a mobile phase linear gradient and monitored by UV detection at 343nm. Chloroquine and Oxytetracycline were used as internal standards. Lower and upper limits of quantifications, as well as the other levels of calibration, were validated with acceptable accuracy (<15% deviation) and precision (<15% coefficient of variation) according to the European Medicines Agency guidelines...

BACKGROUND: The 72 hour fast is used to document Whipple's triad and understand the mechanism of hypoglycemia. Although hypoglycaemia develops within 24 hours in the majority of fasts, identifying possible determinants of fast duration may help to predict the need for admission. Therefore we determined the relation between anthropometric features on fast duration and assessed end of fast parameters on maximal tumor size, extent of disease or tumor recurrence. METHODS: A retrospective analysis of patients with insulinoma in the past 25 years who underwent a 72 hour fast conducted...

Evolutionary theories of senescence predict that a high allocation to reproduction during early life should have long-term deleterious consequences on future reproduction or survival because individuals have to face an energy allocation trade-off between reproductive effort and the maintenance of body condition. Using a high-quality dataset from 1,721 red ruffed lemurs (RRL, Varecia rubra) and 3,637 black and white ruffed lemurs (BWRM, V. variegata) living in captivity, we tested the existence of a trade-off between reproductive effort and late-life survival after accounting for possible confounding effects of natal environmental conditions...

INTRODUCTION: Injuries are one of the most common reasons for emergency department visits, with approximately 40.2 million injury-related visits occurring in 2011. Facial, hand, and wrist injuries make up a large portion of these visits. Despite the high demand for specialists to attend to these injury-related emergency department visits, recent studies have suggested a discrepancy between elective surgical coverage and trauma care in general. The goal of this study was to determine if there was a difference between access to elective surgical procedures in comparison with on-call emergency care for facial and hand/wrist conditions in New York State...

PURPOSE OF REVIEW: Just as gastrointestinal dysfunction may develop in the setting of neurologic disease, neurologic dysfunction may become evident in the setting of gastrointestinal disease. This article describes the range of neurologic features that have been described in three primary gastrointestinal diseases: celiac disease and gluten-related disorders, inflammatory bowel disease, and Whipple disease. Particular emphasis is placed on the controversial and evolving clinical picture of neurologic dysfunction in disorders of gluten sensitivity...

An insulinoma is a rare tumour with an incidence of four cases per million per year in adults. The incidence in children is not established. There is limited literature available in children with insulinoma, and only one case is reported in association with Down's syndrome in adults. Insulinoma diagnosis is frequently missed in adults as well as in children. The Whipple triad is the most striking feature although it has limited application in young children. Hypoglycaemia with elevated insulin, C-peptide and absent ketones is highly suggestive of hyperinsulinism...

Background: Classical Whipple's disease (CWD) is characterized by the lack of specific Th1 response towards Tropheryma (T.) whipplei in genetically predisposed individuals. The cofactor GrpE of heat-shock protein 70 (Hsp70) from T. whipplei was previously identified as B-cell antigen. We tested the capacity of Hsp70 and GrpE to elicit specific pro-inflammatory T-cell responses.Methods: Peripheral mononuclear cells from CWD patients and healthy donors were stimulated with T. whipplei lysate or recombinant GrpE or Hsp70 before CD40L, CD69, perforin, granzyme B, CD107a, and interferon (IFN)γ were determined in T cells by flow cytometry...

BACKGROUND: Whipple's disease, a rare chronic infectious disorder caused by Tropheryma whipplei, may present with predominant joint manifestations mimicking rheumatoid arthritis (RA). METHODS: A retrospective single-center cohort study of seven patients was performed. Clinical symptoms were assessed by review of medical charts and Whipple's disease was diagnosed by periodic-acid-Schiff-stain and/or Tropheryma whipplei-specific polymerase-chain-reaction. RESULTS: Median age at disease onset was 54 years, six patients were male...

BACKGROUND: Two-stage revision remains the most common approach to periprosthetic joint infection of total hip arthroplasty (THA) in the United States. The postoperative risks associated with removal of an infected prosthesis and placement of a spacer have not been thoroughly studied. METHODS: Patients who underwent THA implant removal and spacer placement for infection were identified in a large administrative database. Morbidity and mortality rates were assessed for the 90-day postoperative period and readmission rates were assessed at 30 days postoperatively...
