Benign paroxysmal positionell vertigo - vanlig orsak till yrsel. Enkel behandling kan ge snabb bot

Vertigo and dizziness are frequent symptoms among patients in primary health care. Benign Paroxysmal Positional Vertigo (BPPV) is one common cause of dizziness with, for the patient, alarming symptoms. It is relatively easy to diagnose, with manouvertreatment or habituation-exercises as effective treatments. The treatment with either Semont or Epley manoeuvres is so effective that it often appears

Enhetliga analyser av narkotika i urin krävs för rättssäkerheten.

Drugs of abuse testing is used in various areas of society for detection and follow-up of drug use. In routine laboratory drug testing, immunoassays are employed for initial screening of specimens to indicate the presence of drugs. To confirm a positive screening test, a secondary analysis by mass spectrometry is performed. The »cut-off« is the pre-defined concentration threshold of a drug or drug

Prostacyclin reduces elevation of intracranial pressure and plasma volume loss in lipopolysaccharide-induced meningitis in the cat.

BACKGROUND: Severe meningitis may compromise cerebral perfusion through increases in intracranial pressure (ICP) and through hypovolemia caused by a general inflammation with systemic plasma leakage. From its antiaggregative/antiadhesive and permeability-reducing properties, prostacyclin (PGI2) is a potential adjuvant treatment in meningitis, but previously published data have been ambiguous. The

An improved version of the basic sphere decoder

In this paper we derive and evaluate by receiver tests a method for pruning tree representations of MIMO signals. The efficiency of the method is compared to that of standard tree pruning used for sphere decoders for several different MIMO system setups. The outcome is that savings up to 50\% compared to the standard sphere decoder are possible.

Behandling av terapiresistent epilepsi - ett multiprofessionellt samarbete

Epilepsi är den vanligaste neurologiska sjukdomen efter stroke och huvudvärk, ca 60 000 personer har aktiv epilepsi i Sverige. Vi har idag tillgång till en rad mycket effektiva läkemedel, bara sedan 1989 har åtta nya epilepsimediciner registrerats. Trots den utvidgade behandlingsarsenalen bli bara två av tre patienter anfallsfria av läkemedel, för en tredjedel fortsätter anfallen att komma. Vid fa

Statistical analysis of arthroplasty register data.

Abstract Data from arthroplasty registers are often analyzed using survival methods. Several methodological problems exist, for example relating to competing events, non-random censoring, non-proportional hazards and dependent observations. League tables and ranking of specific survival results leds to further methodological difficulties. Most of these problems are, however, well known and a numbe
