Validation of the BiteStrip screener for sleep bruxism.

Objective: The aim of this study was to validate a small electronic electromyographic device (BiteStrip) designed to screen masseter electromyographic events that indicate sleep bruxism (SB) against traditional masseter electromyographic events (MEMG).

Study Design: Six SB treatment-seeking patients, 4 obstructive sleep apnea (OSA) patients and 8 symptom-free controls, underwent overnight polysomnography, including MEMG and BiteStrip recordings. Total BiteStrip and MEMG scores and indices (events per hour) based on total recording time (TRT) and total sleep time (TST) were computed.

The KickStrip: a novel testing device for periodic limb movement disorder.

Study Objectives: In light of the ongoing debate over the clinical significance of periodic limb movement disorder (PLMD) and its monitoring in overnight sleep studies, we introduce a novel, portable, low-cost device for PLMD testing. The KickStrip is a disposable device, which includes a movement sensor, a central processing unit with real-time software, and a display. In the present study, the KickStrip final score (Kscore) is validated against the traditional periodic limb movement index (PLMI) based on overnight recordings in the sleep laboratory.

The SleepStrip: an apnoea screener for the early detection of sleep apnoea syndrome.

Sleep apnoea svndrome (SAS) is a largely undiagnosed and prevalent disorder. It is associated with cardiovascular morbidity as well as excessive daytime sleepiness and poor quality of life. In the present study the SleepStrip, a novel screening device is introduced, which is low cost and easy to use and is aimed for widespread use.

Gastrointestinal patients in the emergency room.

Of 4,839 patients who visited the Emergency Room (ER) of a 650-bed general hospital (serving a regional population of 220,000) over a period of 28 consecutive days, 436 were suffering from gastrointestinal (GI) problems. The patients, together with their 140 ER doctors, were interviewed by 40 trained interviewers and information concerning demographic data, tests performed, diagnosis, treatment and hospitalization was collected and evaluated. Most of the GI patients (39.

Tangential low-velocity missile wound of the head with acute subdural hematoma: case report.

Tangential missile wounds of the head without skull fracture are a known entity. Usually, references in the literature indicate that this type of injury results from a high-velocity missile impact. We present a case of a tangential missile head wound caused by a low-velocity missile.

Microbiologic flora contaminating open fractures: its significance in the choice of primary antibiotic agents and the likelihood of deep wound infection.

A clear understanding of the significance of wound contamination as well as knowledge of the microbial flora that could be expected are needed in order to administer a rational and effective antibiotic treatment for open fractures. We have conducted a prospective study of the contaminating microbial flora in 89 open fractures. In addition, two more cultures were taken of all wounds not primarily closed.

Limitation of amylase creatinine clearance ratio as a diagnostic test for postoperative pancreatitis.

The mean +/- S.E.M.

Experimental acute pancreatitis. Inducement by taurocholate sodium-trypsin injection into a temporarily closed duodenal loop in the rat.

Experimental pancreatitis induced by permanently closed duodenal loop results in death of the experimental animal. Acute pancreatitis can be induced in the rat by injection of taurocholate sodium-trypsin solution intraluminally into a temporarily occluded duodenal loop. Mortality in this model was 45% within one week after injection.

Mass in the head of the pancreas in cholestatic jaundice: carcinoma or pancreatitis?

The clinical, biochemical and radiological findings in 16 patients with carcinoma of the head of the pancreas were compared with that of 13 with cholestatic jaundice due to chronic pancreatitis. Patients presenting with malignancy had more severe hyperbilirubinemia (18.5 +/- 2.

Percutaneous transhepatic cholangiography: an experience with the Chiba needle.

Percutaneous transhepatic cholangiography (PTC) with a "skinny" Chiba needle identified the biliary tree in 30 of 31 patients (97%) with extrahepatic obstructive cholestasis (EHC). The method was successful in only eight of 18 patients who had cirrhosis with unexplained jaundice. The biliary tree was visualized after one or two attempts in 23 of 31 patients with EHC (74%).

Number and Types of Element Combinations and the Directedness of Instructions as They Affect Solutions on the Selection Task.

Factors influencing high school and university students' abilities to solve a conditional proposition were examined. Ninety-four male and female Ss were administered a directed or nondirected form of questioning for the selection task. The classic task involves presenting four cards (red, blue, 5, 7) with a conditional proposition rule "Every card with red on one side has 7 on the other" and the instructions to select the cards that would show the rule to be true or false.
