Emotion recognition from facial expressions: a normative study of the Ekman 60-Faces Test in the Italian population.
2013
The Ekman 60-Faces (EK-60F) Test is a well-known neuropsychological tool assessing emotion recognition from facial expressions. It is the most employed task for research purposes in psychiatric and neurological disorders, including neurodegenerative diseases, such as the behavioral variant of Frontotemporal Dementia (bvFTD). Despite its remarkable usefulness in the social cognition research field, to date, there are still no normative data for the Italian population, thus limiting its application in a clinical context. In this study, we report procedures and normative data for the Italian version of the test. A hundred and thirty-two healthy Italian participants aged between 20 and 79 years…
The IHS classification criteria for migraine headaches in adolescents need minor modifications
1996
The operational and diagnostic criteria for migraine and all other headache disorders released in 1988 by the International Headache Society are universally considered reliable and exhaustive. These criteria, however, cannot be considered as satisfactory for population-based studies on migraine prevalence, especially if adolescents are the subjects of the study. Using these diagnostic criteria, we conducted an epidemiological study in order to assess the prevalence of migraine headache in a student population aged 11 to 14 years. Our survey made it possible to code IHS 1.1 (migraine without aura) in 2.35%, IHS 1.2 (migraine with aura) in 0.62%, IHS 1.7 (migrainous disorders not fulfilling m…
Diagnosis of Influenza: Only a Problem of Coding?
2013
<b><i>Objective:</i></b> To evaluate the characteristics of hospital discharge diagnoses of influenza measured by using specific International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9 CM) codes. <b><i>Subjects and Methods:</i></b> The study was conducted for the 3 years 2007, 2008 and 2011. The database included (1) administrative and clinical data on Sicilian patients admitted to acute care hospitals and (2) data from the influenza virological surveillance of 10 European countries (FluNet database). All Sicilian patients diagnosed with at least 1 ICD-9 CM code for influenza (487.0, 487.1 and 487.9) were considere…
MRI radiomics-based machine-learning classification of bone chondrosarcoma.
2019
Abstract Purpose To evaluate the diagnostic performance of machine learning for discrimination between low-grade and high-grade cartilaginous bone tumors based on radiomic parameters extracted from unenhanced magnetic resonance imaging (MRI). Methods We retrospectively enrolled 58 patients with histologically-proven low-grade/atypical cartilaginous tumor of the appendicular skeleton (n = 26) or higher-grade chondrosarcoma (n = 32, including 16 appendicular and 16 axial lesions). They were randomly divided into training (n = 42) and test (n = 16) groups for model tuning and testing, respectively. All tumors were manually segmented on T1-weighted and T2-weighted images by drawing bidimensiona…
Assessment of functional outcomes in patients with head and neck cancer according to the International Classification of Functioning, Disability and …
2013
Background The International Classification of Functioning, Disability and Health Core Set for Head and Neck Cancer (ICF-HNC) covers the typical spectrum of problems in functioning in head and neck cancer. This study is part of a multistep process to develop practical guidelines in Germany. The purpose of this study was to identify instruments for the assessment of functioning using the ICF-HNC as reference. Methods Four Delphi surveys with physicians, physiotherapists, psychologists, and social workers were performed to identify which aspects of the ICF-HNC are being treated and which assessment tools are recommended for the assessment of functioning. Results Ninety-seven percent categorie…
Validity and reliability of the Migraine-Treatment Optimization Questionnaire.
2009
Our aim was to establish the validity and reliability of a patient-rated Migraine Treatment Optimization Questionnaire (M-TOQ in primary care. Patients who met International Classification of Headache Disorders, 2nd edn criteria for migraine completed a 19-item questionnaire containing candidate items for the M-TOQ and three questionnaires designed to test convergent/construct validity [Migraine Disability Assessment Scale (MIDAS), Headache Impact Test (HIT)-6 and Migraine-Specific Quality of Life Scale (MSSQoL)]. A 15-item (M-TOQ15) and a five-item (M-TOQ-5) questionnaire were derived. Two hundred and fifty-three adult patients were recruited. Five treatment optimization domains were iden…
Long-term outcomes of short-term and long-term psychosomatic inpatient treatment and their predictors
2007
Abstract Objectives The Clinic for Psychosomatic Medicine and Psychotherapy at the University Giessen, Germany, offers short-term (STT) and long-term inpatient therapy (LTT). Methods In a prospective, 3-year follow-up study, we examined therapeutic indication, short- and long-term results, outcome predictors, and the utilization of aftercare for both settings. Results STT patients were more frequently acutely ill, suffered from stronger symptomatic manifestations, and were more frequently employed. LTT patients had a greater rate of chronic psychosomatic disorders, personality disorders and somatic comorbidity. In both settings, distress strongly declined during inpatient therapy and remain…
Helicobacter pylori infection does not affect the early rebleeding rate in patients with peptic ulcer bleeding after successful endoscopic hemostasis…
2003
Background and study aims Eradication of Helicobacter pylori infection can reduce the rebleeding rate of peptic ulcer bleeding in the long term. There are few data on the influence of H. pylori on the rebleeding rate in the acute phase of bleeding however. We therefore prospectively investigated the influence of H. pylori infection on the early rebleeding rate in patients who had undergone successful endoscopic hemostasis treatment for peptic ulcer bleeding. Patients and methods Between January 1996 and November 2000 all patients with peptic ulcer bleeding were evaluated consecutively. The diagnosis of H. pylori infection was made at index endoscopy, using histology and the rapid urease tes…
The Calgary Depression Rating Scale for schizophrenia in a healthy control group: Psychometric properties and reference values
2005
Abstract Background Assessment of depression in schizophrenia is of great importance as depressive signs and symptoms and suicidality are highly prevalent in patients with schizophrenic disorders. The Calgary Depression Rating Scale (CDSS) is the standard assessment instrument for that purpose due to its proven reliability and validity. However, so far no reference values derived from an adequate healthy sample have been published. Methods The present study analyzed CDSS item scores and summary scores in 154 healthy subjects (49% female, mean age 32.8 ± 11.7 years) selected from studies as controls for schizophrenic patients. Results The total CDSS score was 2.6 ± 2.7 (range 0–12), about 1/…
Confirmation that the AKT1 (rs2494732) genotype influences the risk of psychosis in cannabis users.
2012
Background Cannabis use is associated with an increased risk of psychosis. One study has suggested that genetic variation in the AKT1 gene might influence this effect. Methods In a case-control study of 489 first-episode psychosis patients and 278 control subjects, we investigated the interaction between variation at the AKT1 rs2494732 single nucleotide polymorphism and cannabis use in increasing the risk of psychosis. Results The rs2494732 locus was not associated with an increased risk of a psychotic disorder, with lifetime cannabis use, or with frequency of use. We did, however, find that the effect of lifetime cannabis use on risk of psychosis was significantly influenced by the rs24947…
