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...

BACKGROUND: Endoscopic ultrasound guided fine needle aspiration (EUS-FNA) is the procedure of choice to investigate and sample pancreatic masses for the preoperative diagnosis of pancreatic ductal adenocarcinoma (PDAC). The role of (18)fluoro-deoxyglucose positron emission tomography/computed tomography (PET/CT) in PDAC is debated. This study evaluates the role of EUS-FNA as compared to PET/CT in the preoperative evaluation of PDAC. METHODS: Preoperative evaluation by PET/CT and EUS-FNA was performed on 25 patients with pancreatic solid lesions, who underwent a subsequent Whipple procedure or partial pancreatic resection...

Between 1940 and 2004, more than 335 emerging infectious disease events were reported in the scientific literature. Themajority (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...

Iatrogenic duodenal injuries are rare complications of upper gastrointestinal endoscopic procedures, gallbladder, and right kidney operations. Management includes diverse options depending on a number of factors that include the size of the injury, timing of presentation, degree of peritoneal contamination, and presence of peritonitis and/or sepsis, etc. While most duodenal injuries are small, large complex non-reconstructable injuries may occasionally occur, requiring complex surgical procedures rather than primary repair which if done in the latter cases, may lead to further morbidity and mortality...

Laparoscopic pancreaticoduodenectomy (LPD) is a minimally invasive approach for Whipple by total or assistant laparoscopic techniques. The results of feasibility, safety, short and long outcomes have slowly been gaining acceptance over the past decade. Aim to further adapt to the development trend, improve the safety and oncologic outcomes, promote the standardized development of LPD in China, four pancreas surgery groups in China wrote this LPD consensus. The consensus includes seven sections: operator request, indications and contraindications, preoperative preparation and anesthesia, equipment and instruments, positioning of patient and trocars, abdominal pressure, indications of conversion to laparotomy, postoperative observation and treatment...

BACKGROUND: NSQIP Risk Calculator was developed to allow surgeons to inform their patients about their individual risks for surgery. Its ability to predict complication rates and length of stay (LOS) has made it an appealing tool for both patients and surgeons. However, the NSQIP Risk Calculator has been criticized for its generality and lack of detail towards surgical subspecialties, including the hepatopancreaticobiliary (HPB) surgery. We wish to determine whether the NSQIP Risk Calculator is predictive of post-operative complications and LOS with respect to Whipple's resections for our patient population...
