Pleasant music as a countermeasure against visually induced motion sickness.

2013

Visually induced motion sickness (VIMS) is a well-known side-effect in virtual environments or simulators. However, effective behavioral countermeasures against VIMS are still sparse. In this study, we tested whether music can reduce the severity of VIMS. Ninety-three volunteers were immersed in an approximately 14-minute-long video taken during a bicycle ride. Participants were randomly assigned to one of four experimental groups, either including relaxing music, neutral music, stressful music, or no music. Sickness scores were collected using the Fast Motion Sickness Scale and the Simulator Sickness Questionnaire. Results showed an overall trend for relaxing music to reduce the severity o…

Hysteroscopic resection of the septum improves the pregnancy rate of women with unexplained infertility: a prospectine controlled trial

2009

Objective: To assess fecundity of infertile women after surgical correction of uterine septum. Design: Prospective controlled trial. Setting: Three academic infertility clinics. Patient(s): Forty-four women affected by septate uterus and otherwise unexplained infertility represented the study group (group A), and 132 women with unexplained infertility were enrolled as control subjects (group B). Intervention(s): Hysteroscopic metroplasty was performed in group A, and group B was managed expectantly. All women were followed-up for 1 year without any other intervention. Main Outcome Measure(s): Fecundity rate was calculated as the number of pregnancies per 100 person-months Result(s): Pregnan…

What are the risk factors for postoperative infections of third molar extraction surgery: A retrospective clinical study-?

2018

Background This study aimed to identify (1) the predilection site of postoperative infection after third molar extraction surgery, (2) risk factors associated with postoperative infection, and (3) the cause of the difference between delayed- and early-onset infections. Material and Methods This retrospective study included 1010 patients (396 male, 614 female) who had ≥1 third molars extracted (2407; 812 maxilla, 1595 mandible). The risk factors were classified as attributes, general health, anatomic, and operative. Outcome variables were delayed- and early-onset infections. Results Postoperative infection was completely absent in the maxilla, and all infections occurred in the mandible, wit…

Once-Daily Oral Levofloxacin Monotherapy versus Piperacillin/Tazobactam Three Times a Day: A Randomized Controlled Multicenter Trial in Patients with…

2004

A prospective, randomized, controlled multicenter trial was performed to evaluate the efficacy and safety of once-daily oral monotherapy with 500 mg levofloxacin in comparison with 4.5 g piperacillin/tazobactam 3 times a day in patients with low-risk febrile neutropenia. Low risk was defined by oral temperatureor = 38.5 degrees C on one occasion oror = 38.0 degrees C twice within 24 hours and granulocytopeniaor = 500/microL for less than 10 days. The primary end point was defined as defervescence after 72 hours followed by at least 7 afebrile days. Secondary end points were overall response, time to defervescence, survival on day 30, and toxicity. Thirty-four episodes were included. Fever o…

Microvascular injury and repair in acute human bacterial pyelonephritis.

1987

Acute inflammatory cell-capillary endothelial cell interactions, related to injury and repair, were investigated light and electron microscopically in acute human bacterial pyelonephritis. In inflammatory infiltrate-adjacent microvessels, the small capillaries were completely occluded by leukocyte plugs and the large capillaries were densely filled with acute inflammatory cells adhering to the endothelium. Severe damage to small and large capillaries was observed around endothelium adherent, degranulated neutrophil granulocytes containing phagocytosed bacteria. There were spaces in the endothelium, degradation of the vascular basement membrane, of the perivascular interstitial matrix and of…

A nationwide survey of hereditary angioedema due to C1 inhibitor deficiency in Italy

2014

Introduction Hereditary angioedema due to C1-inhibitor deficiency (C1-INH-HAE type I) or dysfunction (C1-INH-HAE type II) is a rare disease characterized by recurrent episodes of edema with an estimated frequency of 1:50,000 in the global population without racial or gender differences. In this study we present the results of a nationwide survey of C1-INH-HAE patients referring to 17 Italian centers, the Italian network for C1-INH-HAE, ITACA. Methods Italian patients diagnosed with C1-INH-HAE from 1973 to 2013 were included in the study. Diagnosis of C1-INH-HAE was based on family and/or personal history of recurrent angioedema without urticaria and on antigenic and/or functional C1-INH def…

Accuracy of two plasma antibody tests and faecal antigen test for non-invasive detection of H. pylori in middle-aged Caucasian general population sam…

2018

The aim of the study was to assess the accuracy of two plasma Helicobacter pylori (H. pylori) antibody test-systems and a stool antigen test (SAT) system in a general population sample in Latvia.Blood and faecal samples were analysed in healthy individuals (40-64 years), referred for upper gastrointestinal endoscopy according to pilot study protocol within a population-based study investigating gastric cancer prevention strategies (GISTAR pilot study). Antibodies to H. pylori were assessed in plasma by latex-agglutination test and enzyme-linked immunosorbent assay (ELISA). H. pylori antigen in faecal samples was detected by a monoclonal enzyme immunoassay-based SAT. Histological assessment …

vacA genotypes in oral cavity and Helicobacter pylori seropositivity among adults without dyspepsia.

2010

Objective: The aims of this research were to determine the prevalence of Helicobacter pylori and its vacA genotypes in oral cavity in persons without dyspepsia and to establish the association between the presence of H. pylori in oral cavity and oral hygiene. The seroprevalence of anti-H. pylori antibodies and its associated factors were analyzed too. Study design: For the study, 200 adults without dyspepsia symptoms were selected. Dental plaque and saliva samples from each subject were obtained. H. pylori detection in oral samples was carried out by polymerase chain reaction (PCR) and for vacA genotyping a semi-nested and nested PCR was used. The enzyme-linked immunosorbent assay (ELISA) w…

Granzyme A as a potential biomarker of Mycobacterium tuberculosis infection and disease

2015

Cytotoxic molecules such as granulysin, perforin and granzymes produced by cytolytic T cells directly contribute to immune defense against tuberculosis (TB). In search for novel TB biomarkers, we have evaluated the levels of granzyme A in plasma obtained from QuantiFERON-TB Gold In tube (QFT-IT) assays from patients with active TB disease and subjects with latent TB infection (LTBI).Granzyme A serum levels in TB patients were significantly lower than values found in LTBI subjects even after subtraction of the unstimulated levels from the antigen-stimulated responses. The receiver operator characteristics (ROC) curve analysis comparing TB patients and LTBI groups, showed that at a cut-off va…
