Epidemiologic study of odontogenic and non-odontogenic cysts in children and adolescents of a Brazilian population
2017
Background The objective of this study was to describe the frequency of cystic lesions in a Brazilian population of patients histopathologically diagnosed in the first and second decade of life. Material and Methods Retrospective descriptive cross-sectional study was performed. Biopsy records were obtained from the archives of a Brazilian referral center between 1980 and 2016. Results A total of 2.114 biopsy records of pediatric patients were analyzed with oral and maxillofacial lesions. Data such as gender, age, anatomical location, and histopathological diagnosis were collected and categorized. Among all oral and maxillofacial lesions (n=2.114), were diagnosed 294 cases of odontogenic cys…
Pediatric Germ Cell Tumors From 1987 to 2011: Incidence Rates, Time Trends, and Survival
2014
BACKGROUND: Malignant germ cell tumors (GCTs) are a rare and a heterogeneous group of pediatric cancers. The incidence rate has increased in some populations or subgroups. However, only a few recent publications on epidemiologic data showing the trends in incidence of pediatric GCTs are available. METHODS: We analyzed the incidence rates, time trends, and survival for 1366 GCTs in children 0 to 14 years old registered in the nationwide, population-based German Childhood Cancer Registry in 1987–2011. RESULTS: The incidence rate of GCTs was slightly higher in girls (age-standardized rate: girls, 5.3; boys, 4.4 per million). A bimodal age distribution was seen. In children aged <1 year…
Prevalence of Toscana and Sicilian Phlebovirus Antibodies in Classic Kaposi Sarcoma Case Patients and Control Subjects in Sicily
2011
To assess whether arthropod bites promote Kaposi sarcoma (KS), we determined the seroprevalence of Sicilian (SFSV) and Toscana (TOSV) phlebovirus antibodies in 30 patients with classic KS and 100 controls in Sicily. Nine (6.9%) subjects, all controls, were positive for SFSV, whereas 41 (31.5%) were positive for TOSV. Seroprevalence with immunoglobulin (Ig) M or IgG against either virus was significantly higher in controls (43% vs 13.3% in case patients; P < .01). Adjusted for age, IgG seroprevalence was significantly lower in KS patients compared to controls (adjusted odds ratio, 0.22; 95% confidence interval, .07–.72). Low phlebovirus seroprevalence in patients with KS may reflect incapaci…
Adverse metabolic response to regular exercise: Is it a rare or common occurrence?
2012
Background. Individuals differ in the response to regular exercise. Whether there are people who experience adverse changes in cardiovascular and diabetes risk factors has never been addressed. Methodology/Principal Findings. An adverse response is defined as an exercise-induced change that worsens a risk factor beyond measurement error and expected day-to-day variation. Sixty subjects were measured three times over a period of three weeks, and variation in resting systolic blood pressure (SBP) and in fasting plasma HDL-cholesterol (HDL-C), triglycerides (TG), and insulin (FI) was quantified. The technical error (TE) defined as the within-subject standard deviation derived from these measur…
Comparative study of serine-plasmalogens in human retina and optic nerve: identification of atypical species with odd carbon chains
2012
International audience; The objective of this work was to detect and identify phosphatidylserine plasmalogen species in human ocular neurons represented by the retina and the optic nerve. Plasmalogens (vinyl-ether bearing phospholipids) are commonly found in the forms of phosphatidylcholine and phosphatidylethanolamine in numerous mammalian cell types, including the retina. While their biological functions are still unclear, the alteration of cellular plasmalogen content has been associated with several human disorders such as Rhizomelic Chondrodysplasia Punctata Type 2 and Primary Open-Angle Glaucoma.By using liquid-chromatography coupled to high resolution and tandem mass spectrometry, we…

Depressed mood and body mass index as predictors of muscle strength decline in old men
2000
OBJECTIVE: To study depressed mood as a predictor of strength decline within body weight categories over a 3-year follow-up period. DESIGN: A prospective cohort study over 3 years. SETTING: Honolulu, Hawaii. PARTICIPANTS: The subjects were 2275 men participating in the Honolulu Heart Program with an average age of 77.1 years (range 71–92 years), who were not cognitively impaired at baseline (Exam 4), and who participated in maximal hand grip strength measurements at baseline and 3 years later (Exam 5). MEASUREMENTS: Hand grip strength was measured using a dynamometer. Depressive symptoms were studied using an 11-item version of Center for Epidemiologic Studies Depression Scale with 9 as a c…
Strongyloidiasis in northern Vietnam: epidemiology, clinical characteristics and molecular diagnosis of the causal agent.
2019
Abstract Background Strongyloidiasis is a health problem in Vietnam, but appropriate information is still limited. The aim of this study was to determine the prevalence, geographical distribution, epidemiological aspects, symptoms and other health indicators of Strongyloides stercoralis infections in patients from 27 provinces of northern Vietnam attending the Hanoi Medical University Hospital during 2016 and 2017. Methods Blood samples of 2000 patients were analyzed for S. stercoralis infection with an IgG ELISA test. Seroprevalence was analyzed by gender, age group, locality of origin (rural or urban areas) and symptoms. Stools from the seropositive patients were examined for the detectio…
Assessment of humoral and cell-mediated immunity against Bordetella pertussis in adolescent, adult, and senior subjects in Italy
2008
SUMMARYHumoral and cell-mediated immunity (CMI) againstB. pertussiswas assessed in a sample of adolescent, adult and senior subjects distributed in five different geographical areas in Italy. Most (99·1%) subjects had IgG anti-pertussis toxin (PT) antibodies exceeding the minimum detection level [⩾2 ELISA units (EU)/ml]. There were no significant differences between the genders; 6·2% samples recorded titres ⩾100 EU/ml. CMI was positive [stimulation index (SI) ⩾5] against PT in 39·0% of all samples. This study suggests thatB. pertussiscontinues to circulate in age groups that have been previously considered to be uninvolved in the circulation of this pathogen and that adolescent and adult pe…
