Multifocal intraductal tubulopapillary neoplasm of the pancreas with total pancreatectomy: report of a case and review of literature.

Intraductal neoplasms of the pancreas are classified as intraductal tubulopapillary neoplasms (ITPNs) and intraductal papillary mucinous neoplasm (IPMNs) in the current WHO classification. ITPN is a rare tumor and there are only a few cases of ITPN reported in the literature. We present the case of an otherwise healthy 42-year-old male, who presented with upper abdominal pain. He was subsequently

The LUSEM Case method – an alternative approach? – some reflections on hands on learning and abstract knowledge.

The MBA case method of how to use cases steam from Harvard and has almost become a norm for what the case method represents concerning the purpose, form and content. However, the Lund University School of Economics and Management (LUSEM) way of using cases differs from the MBA Case Method in several important aspects. This paper discusses the potential merits of using an alternative approach (LUSE

Passive knee muscle moment arms measured in vivo with MRI

OBJECTIVE: To determine moment arm lengths from seven knee muscles and the patellar tendon. The knee muscles were the biceps femoris, semitendinosus, semimembranosus, gracilis, sartorius, and the lateral and medial gastrocnemius muscles. DESIGN: The moment arms were calculated based on MRI measurements. BACKGROUND: Moment arm lengths of different muscles with respect to the joint centre of rotatio

Professionalization, Gender and Anonymity in the Global File Sharing Community

This article presents the analysis of a large survey on file-sharing that was conducted in April 2011 with over 75,000 respondents from all over the world. The study, also known as The Research Bay, due to that it was conducted in collaboration with the infamous BitTorrent site The Pirate Bay, by the Cybernorms research group. The aim of the online study of The Pirate Bay community has been to des

Characterization and treatment of municipal landfill leachates

Popular Abstract in Swedish Ansamlingen av avfall i soptippar skapar miljöproblem då mikrobiell nedbrytning av lättnedbrytbart avfall ger upphov till växthusgaser (metangas och koldioxid). Dessutom bildas förorenade lakvatten på grund av att regnvatten tränger igenom deponin. Lakvattnet innehåller ofta höga halter av ammoniumjoner samt organiska ämnen. Ammoniumjonen är en giftig förening som ger aAbstract The efficiency of different leachate treatment methods for the removal of refractory organic compounds and ammonium-nitrogen was investigated. The methods evaluated were nitrification, denitrification, adsorption onto activated carbon, precipitation by ferric chloride or aluminum sulphate and oxidation by ozone or Fenton´s reagent. Furthermore, analyses were performed on leachates from mu

Halomonas andesensis sp. nov., a moderate halophile isolated from the saline lake Laguna Colorada in Bolivia.

Strain LC6T was isolated from a water sample of the lake Laguna Colorada in the Bolivian Andes. The bacterium was characterized as moderately halophilic, motile, Gram-negative rod. The major fatty acids present in the cell were C18:1omega7c, C16:1omega7c iso 2-OH, C16:0 and C12:0 3-OH. The respiratory ubiquinones found in strain LC6T were Q-9 (97%) and Q-8 (3%). The organism was found to be an aer

The practice of internal medicine in Europe: organisation, clinical conditions and procedures

Background: Current information on the role of internists in the European countries is scarce. This report describes the results of a survey of the practice of internists in Europe. Methods: Two online questionnaire-based surveys were carried out by the European Board of Internal Medicine, one on the practice of internists and the other on postgraduate training in internal medicine. The national i

Importance of proximal hydrogen bonds in haem proteins.

We have used the density functional B3LYP method to study the effect of hydrogen bonds from the histidine ligand in various haem proteins to carboxyl groups or to the carbonyl backbone. Hydrogen bonds to carbonyl groups (encountered in globins and cytochromes, for example) have a small influence on the geometry and properties of the haem site. However, hydrogen bonds to a carboxyl group (encounter

Assessment of objective and subjective eccentric refraction

Purpose. When performing perimetry, refracting subjects with central visual field loss, and in emmetropization studies, it is important to accurately measure peripheral refractive errors. Traditional methods for foveal refraction often give uncertain results in eccentric angles as a result of the large aberrations and the reduced retinal function. The aim of this study is therefore to compare and

The long-term course of depressive disorders in the Lundby Study.

Background. The Lundby Study is a longitudinal cohort study on a geographically defined population consisting of 3563 subjects. Information about episodes of different disorders was collected during field investigations in 1947, 1957, 1972 and in 1997. Interviews were carried out about current health and past episodes since the last investigation; for all subjects information was also collected fr

Socio-economic status and lung cancer risk including histologic subtyping-A longitudinal study.

We investigated prospectively the risk of lung cancer in relation to socioeconomic status (SES) in 22387 middle-aged individuals who attended a screening program in the city of Malmo, Sweden between 1974 and 1992. We also examined the relationship between SES and histologic subtype in smokers. By 2003, a total of 550 lung cancer cases had been identified. Relative risks (RR) were calculated with a

Measurement Techniques for Respiratory Tract Deposition of Airborne Nanoparticles: A Critical Review.

Abstract Determination of the respiratory tract deposition of airborne particles is critical for risk assessment of air pollution, inhaled drug delivery, and understanding of respiratory disease. With the advent of nanotechnology, there has been an increasing interest in the measurement of pulmonary deposition of nanoparticles because of their unique properties in inhalation toxicology and medicin

Familial risk of sleep-disordered breathing

Objective: To estimate the incidence of hospitalization for paediatric obstructive sleep apnoea syndrome (OSAS) or sleep-disordered breathing (SDB) caused by adenotonsillar or tonsillar hypertrophy without infection in children with a parent affected by OSAS. Patients and methods: Using the MigMed database at Lund University, hospital data on all children aged 0-18 years in Sweden between 1997 and

Postgraduate education in internal medicine in Europe

Background: Limited information exists on the framework and content of postgraduate education in internal medicine in Europe. This report describes the results of a survey of postgraduate training in internal medicine in the European countries. Methods: Two online questionnaire-based surveys were carried out by the European Board of Internal Medicine, one on the practice of internists and the othe

The ulcerated leg: when to revascularize

The role of peripheral arterial disease in ulcerated diabetic feet has long been underestimated. Progressive claudication, rest pain and the extent of irreversible tissue loss have frequently been indications for revascularization for neuroischaemic ulcers in diabetic patients. These typical ischaemic symptoms are warning signs that are less frequent in diabetic individuals with ischaemia than tho

Inflammation without neuronal death triggers striatal neurogenesis comparable to stroke.

Ischemic stroke triggers neurogenesis from neural stem/progenitor cells (NSPCs) in the subventricular zone (SVZ) and migration of newly formed neuroblasts towards the damaged striatum where they differentiate to mature neurons. Whether it is the injury per se or the associated inflammation that gives rise to this endogenous neurogenic response is unknown. Here we showed that inflammation without c

Cancer Incidence in a Cohort of Swedish Chimney Sweeps, 1958-2006.

Objectives. We examined cancer incidence in an expanded cohort of Swedish chimney sweeps. Methods. We added male chimney sweep trade union members (1981-2006) to an earlier cohort (employed 1918-1980) and linked them to nationwide registers of cancer, causes of deaths, and total population. The total cohort (n = 6320) was followed from 1958 through 2006. We estimated standardized incidence ratios
