ABSTRACT Objectives: This cross-sectional study was designed to determine the caries status and provide a general evaluation of the level of dental treatment need of Pennsylvania public school children in grades 1, 3, 9, and 11 on a statewide and regional basis. Methods: Between September 1998 and May 2000, caries status and treatment need were assessed using a school-based dental examination, performed on a representative sample (n=6,040) of public school children in grades 1, 3, 9, and 11 (age range=6 to 21 years). Children's caries status in the primary and permanent dentition was assessed. Need for treatment was scored on a three-level categorical scale,no treatment need identified, routine treatment need, and urgent treatment need,and was based on the presence and severity of caries and other oral conditions. Population estimates of the prevalence of untreated dental caries, DMFT and dft scores, and treatment need were calculated by grade and geographically, using the six Pennsylvania health districts and the cities of Pittsburgh and Philadelphia. The inequality of caries distribution in the population was assessed for both permanent and primary caries using Lorenz curves and Gini coefficients. Results: Dental caries has remained highly prevalent among Pennsylvania's public school children. Caries levels varied considerably by health districts and city. Urgent treatment needs were significant and also varied by health district and city. Conclusions: Dental caries remains the most prevalent disease affecting Pennsylvania's schoolchildren. Caries status varies significantly by region of the state, suggesting that environmental, social, and demographic contextual factors may be important determinants of disease prevalence. [source]

Summary Background, Although erosive gastro-oesophageal reflux disease (GERD) is a highly prevalent condition, there is no specific, valid, reliable and sensitive questionnaire that allows evaluating treatment-induced changes in health-related quality of life (HRQoL). Aim, To design a self-administered questionnaire, the GERD Analyzer (GERDyzer), for use in clinical studies. Methods, The GERDyzer comprises 10 dimensions each illustrated by pictogram-like drawings, simplifying communication with the patients. Self-assessment is performed by 100 mm Visual Analogue Scales. For validation, a 5-week clinical trial involving 395 patients (per-protocol) with oesophagitis was conducted. Patients were treated with pantoprazole (40 mg o.d.) for 28 days. Psychometric analyses included internal consistency, test,retest reliability, responsiveness and construct validity. Results, Factor analysis showed consistency of the dimensions and no reduction was necessary. Validation of GERDyzer indicated high internal consistency (Cronbach's , = 0.95) and test,retest reliability (intraclass correlation coefficient =0.91). Responsiveness of the total score expressed by nonparametric effect size was 1.38. Comparison of scores with other questionnaires resulted in logical correlation levels depending on the respected concepts measured. Conclusions, GERDyzer proved to be highly valid, reproducible and responsive. It allows reliably assessing treatment-induced changes in HRQoL in erosive GERD. [source]


Irritable bowel syndrome: patients' attitudes, concerns and level of knowledge

Summary Background Irritable bowel syndrome (IBS) is a common, chronic disorder that reduces patients' quality-of-life. Although highly prevalent, little is known about patients' understanding of this disorder. Aim To evaluate the knowledge, fears and concerns of IBS patients. Methods Seven hundred thirty-six IBS patients (Rome II criteria) were eligible for inclusion in this prospective study. Each patient received a validated questionnaire to evaluate knowledge, attitudes and fears regarding IBS. Results A total of 261 of 664 potential respondents completed the questionnaire (39.3%). 83% of respondents were women, with a mean age of 53.7 years, and mean duration of symptoms of 14.2 years. Patients frequently believed that IBS develops because of anxiety (80.5%), dietary factors (75.1%) and depression (63.2%). Few respondents (28.7%) recognized that abdominal pain is the cardinal symptom of IBS, and 40.6% stated that colonoscopy can diagnose IBS. One in seven patients stated that IBS turns into cancer, and 29.9% noted that IBS increases the risk of inflammatory bowel disease. Conclusions Many IBS patients have significant misconceptions regarding the nature of their disease and its prognosis. An overwhelming majority of IBS patients believe that anxiety, dietary factors and depression cause IBS. These findings are discordant with physicians' views and practices and highlight the need for patient-oriented educational programs. [source]


Recent advances in the neurobiology of anxiety disorders: Implications for novel therapeutics,

AMERICAN JOURNAL OF MEDICAL GENETICS, Issue 2 2008

Abstract Anxiety disorders are a highly prevalent and disabling class of psychiatric disorders. This review focuses on new directions in neurobiological research and implications for the development of novel psychopharmacological treatments. Neuroanatomical and neuroimaging research in anxiety disorders has centered on the role of the amygdala, reciprocal connections between the amygdala and the prefrontal cortex, and, most recently, alterations in interoceptive processing by the anterior insula. Anxiety disorders are characterized by alterations in a diverse range of neurochemical systems, suggesting ample novel targets for drug therapies. Corticotropin-releasing factor (CRF) concentrations are elevated in a subset of anxiety disorders, which suggests the potential utility of CRF receptor antagonists. Pharmacological blockade of the memory-enhancing effects of stress hormones such as glucocorticoids and noradrenaline holds promise as a preventative approach for trauma-related anxiety. The glutamatergic system has been largely overlooked as a potential pharmacological target, although convergent preclinical, neuroimaging, and early clinical findings suggest that glutamate receptor antagonists may have potent anxiolytic effects. Glutamatergic receptor agonists (e.g., D -cycloserine) also have an emerging role in the treatment of anxiety as facilitators of fear extinction during concurrent behavioral interventions. The neuropeptides substance P, neuropeptide Y, oxytocin, orexin, and galanin are each implicated in anxiety pathways, and neuropeptide analogs or antagonists show early promise as anxiolytics in preclinical and/or clinical research. Each of these active areas of research holds promise for expanding and improving evidence-based treatment options for individuals suffering with clinical anxiety. © 2008 Wiley-Liss, Inc. [source]

FRCSC, Serge Carrier MD
ABSTRACT Introduction., Erectile dysfunction (ED) is a highly prevalent, often undertreated condition. Aim., This 12-week, double-blind, parallel, placebo-controlled study was conducted at 25 sites in Canada to evaluate the efficacy and safety of oral tadalafil, a phosphodiesterase type 5 inhibitor, for the treatment of ED. Methods., Men with ED of organic, psychogenic, or mixed etiology were stratified by baseline ED severity then randomly assigned to placebo (N = 50), tadalafil 10 mg (N = 103), or tadalafil 20 mg (N = 100), taken as needed (maximum, once daily). Main Outcome Measures., Efficacy was assessed by the International Index of Erectile Function (IIEF), a Sexual Encounter Profile diary, and a global assessment question (GAQ). Results., Tadalafil 10 mg and tadalafil 20 mg significantly improved erectile function compared with placebo (P < 0.001, all measures). At end point, the mean IIEF erectile function (EF) domain scores were 14.5, 21.2, and 23.3 of a possible score of 30 for placebo, tadalafil 10 mg, and tadalafil 20 mg, respectively. Patients treated with tadalafil reported greater change from baseline on the IIEF EF domain score compared with placebo, regardless of baseline ED severity. During treatment, the mean per-patient proportion of successful intercourse attempts was higher for tadalafil 10 mg and 20 mg than for placebo (placebo, 31.9%; tadalafil 10 mg, 56.7%; and tadalafil 20 mg, 61.5%), and a greater proportion of patients reported improved erections with tadalafil (GAQ; placebo, 22.0%; tadalafil 10 mg, 67.0%; tadalafil 20 mg, 79.0%). Fifty percent and 62% of patients treated with tadalafil 10 mg and 20 mg, respectively, achieved successful sexual intercourse after their first dose, compared with 31% with placebo. Treatment-emergent adverse events were generally mild or moderate. Conclusion., Tadalafil was an effective, well-tolerated therapy for ED of broad-spectrum etiology and severity.

The genetics of panic disorder: state of the art

ACTA NEUROPSYCHIATRICA, Issue 2 2004
Dirk Van West
Panic disorder (PD) is a highly prevalent, debilitating disorder. The heritability of the disease has been estimated by twin studies to be between 30 and 60%. The vulnerability for PD overlaps with an increased risk of bipolar disorder in some families. Classical genetic methods such as linkage analysis and association studies have not yet identified genetic risk factors beyond doubt. However, two independent studies confirm linkage of a specific syndrome characterized by PD, bladder problems, severe headaches, mitral valve prolapse and thyroid dysfunction to genetic markers on chromosome 13q. Association studies, although showing divergent results, give some support to a causative role for the genes encoding for monoamine oxidase A (MAO-A), cholecystokinin (CCK) and catechol-O-methyltransferase (COMT). Finally, a somatic duplication of a 19-Mb region on chromosome 15 has been associated with PD, but this intriguing finding awaits confirmation. [source]
