Changes in microflora in dental plaque from cancer patients undergoing chemotherapy and the relationship of these changes with mucositis: a pilot stu…
2015
Background: To assess changes in oral microflora in dental plaque from cancer patients within 7 days of the first course of chemotherapy, and the relationship of the changes with mucositis. Material and Methods: Thirty cancer patients, divided into a test group undergoing chemotherapy and a control group no undergoing chemotherapy, were enrolled in this pilot study. Oral microflora were cultured from three samples of dental plaque at t0 (before chemotherapy), t1 (1 day after chemotherapy) and t2 (7 days after chemotherapy). Single and crossed descriptive analyses were used to establish prevalence, and the χ 2 test was used to establish the statistical significance of the differences observe…
Subtype-specific incidence of testicular cancer in Germany: a pooled analysis of nine population-based cancer registries.
2009
Summary Comparisons of incidence estimates of testicular cancer subtypes beyond seminoma and non-seminoma are virtually missing in the epidemiologic literature. We analysed incidence data from population-based German cancer registries to provide subtype-specific incidences of testicular cancer. We pooled data from nine cancer registries from 1998 to 2003. We estimated incidence and mortality time trends of West and East Germany. Incidence and mortality were standardized by the European standard population. The annual percentage incidence change from 1961 through 1989 was 4.9% in East Germany and 3.0% from 1970 through 2004 in Saarland. Incidence increases were the most pronounced among adol…
Changes in plasma lecithin: cholesterol acyltransferase activity, HDL2, HDL3 amounts and compositions in patients with chronic renal failure after di…
2002
The aim of this study was to investigate the effect of hemodialysis duration on HDL(2) and HDL(3) compositions and lecithin:cholesterol acyltransferase (LCAT) activity in 58 patients on acetate hemodialysis using cuprophane membrane, after different periods of dialysis. Patients were divided into three groups-GI1 year, GII 1-5 years, GIII 5-13 years of dialysis and were compared with 22 controls. Increase by 34% of triacylglycerols (TG) was noted in GI and by 36% in GII versus GI. Hypertriglyceridemia was correlated with hemodialysis duration (HD) (r=0.75, P0.05). The LCAT activity decrease by 25% was noted in GII versus GI (P0.05) and by 45% in GIII versus GI (P0.01), this activity was neg…
Odontogenic tumors: a collaborative study of 218 cases diagnosed over 12 years and comprehensive review of the literature.
2015
Objectives: The objective of this study was to analyze the frequency and distribution of odontogenic tumors (OTs) in the Cappadocia region of Turkey, and to compare the findings with those reported in the literature. Study Design: The records of the Oral and Maxillofacial Surgery and Pathology Departments at Erciyes University, with histologic diagnosis of odontogenic tumors (based on the World Health Organization classification, 2005), over a 12-year period, were analyzed. The relative frequency of different types of tumors was also analyzed and compared with the literature. Results: OTs in the present study constituted 2.74% of all the 7,942 registered biopsies. A total of 218 cases of OT…
Visualization of corneal vascularization in peripheral hypertrophic subepithelial corneal opacification with OCT angiography.
2018
Purpose The major goal of this study was to test the hypothesis that in patients with peripheral hypertrophic subepithelial corneal opacification (PHSCO), visualization of corneal vessels is better with optical coherence tomography angiography (OCTA) than with conventional slit lamp microphotography. Methods Patients with PHSCO were included in this prospective study. The corneal findings were photographed using a slit lamp camera (Haag Streit BM 900® ) and visualized with anterior-segment OCT (Optovue XR Avanti, Fremont, California, USA). Additionally, OCTA with the Angiovue Imaging™ System was performed in the area of PHSCO. Results Thirty-four eyes of 19 patients (26% male and 74% female…
Choice of spatial frequency for contrast sensitivity evaluation after corneal refractive surgery.
2002
ABSTRACT PURPOSE: To study the utility of measurements of contrast sensitivity at different spatial frequencies as an index of visual recovery following refractive surgery. METHODS: Contrast sensitivity at 1.5, 3, 6, 12, and 18 c/deg was measured with the Stereo Optical FACT chart in 20 patients after photorefractive keratectomy (PRK) using the Nidek EC-5000 excimer laser system, and in 18 patients following laser in situ keratomileusis (LASER). Contrast sensitivity was measured preoperatively and 1, 3, 6, and 12 months after surgery. RESULTS: Results showed a statistically significant reduction (P<01) in contrast sensitivity at all spatial frequencies in PRR patients during the first an…
Urine Testing During Treatntent Predicts Cocaine Abstinence
2010
The objective of this study was to analyze the influence of the variables that predict cocaine abstinence on an outpatient program for the treatment of addiction to this substance. Participants were 80 patients (85% men and 15% women) selected at random from those receiving treatment at a Spanish health service outpatient unit. For detecting the predictor variables the authors carried out a chi-square automatic interaction detection (CHAID) analysis. Logistic regression analysis and discriminant analysis were performed to estimate the probability of abstinence according to/using the predictor variables detected by CHAID analysis. Abstinence rate after six months of treatment was 37.5%. The …
Enzyme activities and glycogen concentration in skeletal muscle in alcoholism. The effect of abstinence and physical conditioning.
1974
. Muscle metabolism of chronic alcoholics has been studied using a muscle biopsy technique immediately after a drinking period, after 6–7 days' abstinence and after one month's physical conditioning. The activities of CPK, HK, LDH, MDH and SDH were significantly decreased in musculus vastus lateralis for 1–2 days after an alcoholic debauch. The enzyme activities of the alcoholics, who either had been abstinent for 6–7 days or in addition conditioned for one month, did not differ from those of the controls. The concentration of muscle glycogen was at the same level in both groups, but in bicycle ergometer work of an equal relative intensity the alcoholics used more glycogen than the control …
Portable PSG for sleep stage monitoring in sports: Assessment of SOMNOwatch plus EEG.
2019
Current sport-scientific studies mostly neglect the assessment of sleep architecture, although the distribution of different sleep stages is considered an essential component influencing an athlete's recovery and performance capabilities. A mobile, self-applied tool like the SOMNOwatch plus EEG might serve as an economical and time-friendly alternative to activity-based devices. However, self-application of SOMNOwatch plus EEG has not been validated against conventional polysomnography (PSG) yet. For evaluation purposes, 25 participants (15 female, 10 male;
Effects of Rapid Weight Loss on Judo Athletes: A Systematic Review
2020
Rapid weight loss (RWL) is commonly practiced among judo athletes. Although it helps them to gain the advantage over their lighter opponents, previous studies have shown that RWL can have a negative impact on the athlete’s performance and overall well-being. This systematic review aimed to synthesize the evidence that examines the influence of rapid weight loss on physiological parameters, biomarkers, and psychological well-being in judo athletes. We followed the preferred reporting items for systematic reviews and meta-analyses guidelines. We searched for studies on Web of Science and PubMed that elaborate on the influence of ≥5% RWL achieved over ≤7-day period in judokas. Out of 52 studie…
