Stool specimens from 102 children (median age = 6.0 years; Helicobacter pylori in biopsy specimens, n = 43) were tested for H. pylori with the monoclonal antibody-based enzyme immunoassay HpStar. In 28 cases, the specimen was obtained with a rectal cotton swab during endoscopy. The sensitivity and specificity of the HpStar were 0.95 and 0.90, respectively, as compared with biopsy-based methods....

Four swab materials were evaluated for their efficiency in recovery of Bacillus anthracis spores from steel coupons. Cotton, macrofoam, polyester, and rayon swabs were used to sample coupons inoculated with a spore suspension of known concentration. Three methods of processing for the removal of spores from the swabs (vortexing, sonication, or minimal agitation) and two swab preparations (premo...

Vulvar vestibulitis syndrome (VVS) is a common form of dyspareunia in premenopausal women. The standard test for diagnosing VVS is the cotton-swab test, during which a cotton-swab is applied to various locations of the vulvar vestibule. However, there is much variation in the implementation of this test relating to the precise vestibular locations palpated, the order of palpation, and the force...

It consists of a (i) glass tube about \ inch in cross section and 8 inches to 9 inches in length slightly bent at a distance of about 1 inch from one open end. This end of the tube is closed by a piece of thin rubber (which may be made from a piece of torn rubber glove) which is stretched and fastened tight with silk thread at the bend of the tube. (?) Swab?a piece of stout copper wire and a pi...

Male reproductive behavior in the Syrian hamster is dependent on both pheromones from the female and the presence of gonadal steroid hormones. The pheromones are contained within female hamster vaginal secretions (FHVS) and stimulate anogenital investigation and mounting by the male. Administration of testosterone to castrated male hamsters facilitates anogenital investigation, mounts, and intr...

Two experiments were carried out to test whether cells which are born in adulthood and migrate to the olfactory bulb of adult male golden hamsters are activated during sexual behaviors, to determine the time course over which such responsiveness appears, and to ask whether activation is specific to sexual cues. In the first experiment, adult male hamsters were injected with 5'-bromodeoxyuridine...

This prospective study was carried in Mahila Chikitsalya and State Zenana Hospital attached to S.M.S. Medical College, Jaipur, between October 1992 to March 1993. Live born male babies delivered during this period were examined for the presence of epstein pearls on the prepuce. Prepucial epstein pearl was cleaned with cotton swab to remove any smegma, which might mimic epstein pearl. Then its s...

PURPOSE Recurrent stress urinary incontinence after sling surgery is a complex problem. A minimally invasive method of correcting recurrent stress urinary incontinence after pubovaginal sling surgery is described. MATERIALS AND METHODS We performed suprapubic sling adjustment in 10 women with recurrent stress urinary incontinence after sling surgery. Of these 10 women 4 had received antibacte...

BACKGROUND Empathy for pain helps us to understand the pain of others indirectly. To better comprehend the processing of empathic pain, we report the frequency-dependent modulation of cortical oscillations induced by watching movies depicting pain using high-density electroencephalography (EEG), magnetoencephalography (MEG), and motor evoked potentials (MEP). METHODS Event-related desynchroni...
