Prevalence of dysphagia in a consecutive cohort of subjects with MS using fibre-optic endoscopy.

INTRODUCTION: Multiple sclerosis (MS) refers to chronic inflammation of the central nervous system including the brain and spinal cord. Dysphagia is a symptom that represents challenges in clinical practice. The aim of the present study was to evaluate the prevalence of dysphagia in an Italian cohort of subjects with MS using the Dysphagia Outcome Severity Score (DOSS), based on fibre-optic endoscopy, and determine factors that correlate with the presence of swallowing problems. MATHERIALS AND METHODS: Data were collected in a multicentre study from a consecutive sample of MS patients, irrespective of self-reported dysphagia. The study included 215 subjects. Possible scores for DOSS range from 7 to 1, with 7 indicating normal swallowing. RESULTS: One hundred twenty-four (57.7%) subjects demonstrated abnormal swallowing and 57 (26.5%) of these had swallowing problems that required nutrition/diet modifications when evaluated objectively with fibre-optic endoscopy. Subjects with dysphagia were more severely disabled and more often had a progressive form of MS, compared to MS subjects with normal swallowing. In subjects with EDSS, < 4, 8 (13.3%), had a DOSS < 4. Seventy-five percent of subjects older than 60 years of age had dysphagia. CONCLUSION: In this sample of MS patients, more nearly 60% showed swallowing problems.

Sleep continuity scale in Alzheimer's disease (SCADS): application in daily clinical practice in an Italian center for dementia.

Sleep disorders can occur in many neurodegenerative disorders; in a previous paper we constructed a scale investigating sleep discontinuity/fragmentation with the aim to obtain a rapidly and easily administered tool suitable for early identification and longitudinal monitoring of sleep disturbances in Alzheimer's disease (AD). We introduced this instrument in the daily clinical practice in a center for dementia; here we present the results of our experience. Two hundred and sixteen AD outpatients referred to the Alzheimer's Disease Assessment Unit at the IRCCS C. Mondino National Neurological Institute, Pavia, Italy, in the period October 2012 to March 2014 were administered the scale. The questionnaire global score was correlated with measures of cognitive, functional and behavioral impairment; a significant association was found with Mini-Mental State (p = 0.005), Activities of Daily Living (p = 0.01), Neuropsychiatric Inventory (p = 0.01) and Clinical Dementia Rating (p = 0.0005). The present data indicate that the previously validated questionnaire proves to be a suitable, rapid and easy to use tool in investigating sleep quality in AD in daily clinical practice. An early identification and longitudinal monitoring of sleep disturbances in AD may improve pharmacological and non-pharmacological interventions.

Prevalence of patient-reported dysphagia in multiple sclerosis patients: an Italian multicenter study (using the DYMUS questionnaire).

OBJECTIVE: Multiple sclerosis (MS) is an inflammatory disease of the central nervous system (CNS) with a chronic course. Dysphagia represents one of the current challenges in clinical practice for the management of MS patients. Dysphagia starts to appear in mildly impaired MS subjects (EDSS 2-3) and becomes increasingly common in the most severely disabled subjects (EDSS 8-9). The aim of the present study was to evaluate the frequency and characteristics of patient-reported dysphagia in MS patients with a multicenter study using the recently developed DYMUS (DYsphagia in MUltiple Sclerosis) questionnaire. DESIGN: Data were collected in a multi-centre, cross-sectional study using a face-to-face structured questionnaire for clinical characteristics and the DYMUS questionnaire. RESULTS: 1875 patients were interviewed. The current study has shown a correlation between patient-reported dysphagia and EDSS and disease course but not with age, gender and disease duration. Questionnaires were divided into "patient-reported dysphagia-yes" (587, 31.3%) and "patient-reported dysphagia-no" (1288, 68.7%). Compared with the patient-reported dysphagia-no group, patients in patient-reported dysphagia-yes group had higher EDSS score (mean EDSS 4.6 vs. 2.8; p<0.001) and had a longer disease duration (mean duration 13 years vs. 11 years; p<0.001), while there was no significant difference in gender (32.7% vs. 30.5% male and 67.3% vs. 69.5% female) and in age composition (46.18 vs. 42.05). CONCLUSIONS: This study represents the largest, multi-centre sample of MS patients evaluated for patient-reported dysphagia utilizing an ad-hoc questionnaire for this condition.

A sleep continuity scale in Alzheimer's disease: validation and relationship with cognitive and functional deterioration.

Considering that disrupted sleep may be detrimental to daytime performance in people with dementia, we set out to construct a questionnaire able to identify sleep patterns potentially associated with clinical and functional disease variables in this population. Two subsets of items indicative of patterns of unstable sleep and of disordered rapid eye movement sleep (REM) were selected. The first included items investigating sleep continuity, with low sleep continuity markers considered indicative of high arousability; the second included items investigating the frequency and quality of dreams and the frequency of clinically identifiable REM sleep behaviour disorder episodes. The questionnaire was administered to 140 outpatients with a diagnosis of mild-to-moderate Alzheimer's disease. The Mini-Mental State Examination (MMSE), Activities of Daily Living (ADL), Instrumental Activities of Daily Living, Neuropsychiatric Inventory and Clinical Dementia Rating (CDR) were administered to quantify cognitive, functional and behavioural impairment. A subscale comprising items investigating sleep discontinuity/fragmentation and showing high internal consistency was constructed and found to correlate significantly with variables considered indexes of cognitive and functional deterioration in AD (MMSE, ADL and CDR). Conversely, it did not prove possible to obtain a subscale of dysfunctional REM phenomena. The use of a rapidly and easily administered sleep scale, like the one we constructed, appears to be suitable for early identification and longitudinal monitoring of sleep disturbances in AD.

Risk factors in medication-overuse headache: a 1-year follow-up study (care II protocol).

To investigate factors influencing prognosis in medication-overuse headache (MOH), we conducted a 12-month follow-up of patients with probable MOH. We recruited 215 patients consecutively admitted to our headache centre for an inpatient detoxification treatment. We analysed likely predictor factors for headache resolution (sex, age, primary headache, psychiatric comorbidity, type and timing of overuse). Mann-Whitney U-test and chi-squared test were used. One year after withdrawal, we had complete data on 172 patients (80%): 38 of these patients (22%) had relapsed into overuse and 134 (78%) had not. The negative prognostic factors for relapse were: intake of more than 30 doses/month (P = 0.004), smoking (P = 0.012), alcohol consumption (P = 0.037), non-confirmation of MOH diagnosis 2 months after detoxification (P = 0.000), and return to overused drug(s) (P = 0.000). The 1-year relapse rate was 22%. The existence of sub-groups of MOH patients with such risk factors could influence treatment strategies.

Validation of the DYMUS questionnaire for the assessment of dysphagia in multiple sclerosis.

Swallowing problems can complicate the course of multiple sclerosis (MS). However, no validated questionnaire for the assessment of dysphagia in MS is currently available. We previously developed a 10-item DYsphagia in Multiple Sclerosis questionnaire (DYMUS). In the present study, this questionnaire was submitted to a validation process. Thirteen Italian MS centres took part in this research in which DYMUS was administered to 1734 consecutive MS patients during routine checkups outside relapse. The questionnaire showed very good internal consistency (Cronbach's alpha = 0.914). It was then subdivided into two subscales, both of which also showed very good internal consistency: Cronbach's alpha was 0.885 for the 'dysphagia for solids' subscale and 0.864 for the 'dysphagia for liquids' subscale. The DYMUS questionnaire was found to be an easy and reliable tool for detecting dysphagia and also for the preliminary selection of patients requiring more specific instrumental analyses, and those suitable for aspiration prevention programmes.

The DYMUS questionnaire for the assessment of dysphagia in multiple sclerosis.

Swallowing problems can be relevant, even if underestimated, in Multiple Sclerosis (MS) patients. However, no specific questionnaire for the assessment of dysphagia in MS is available. We built a questionnaire (DYsphagia in MUltiple Sclerosis, DYMUS) that was administered to 226 consecutive MS patients (168 F, 58 M, mean age 40.5 years, mean disease duration 10.1 years, mean EDSS 3.1) during control visits in four Italian MS Centres. DYMUS was abnormal in 80 cases (35%). The patients who claimed to have swallowing problems had a significantly higher mean DYMUS score that the other patients (p<0.0001). Mean DYMUS scores were significantly higher in the progressive forms (p=0.003). DYMUS values were significantly correlated to EDSS (p=0.0007). DYMUS showed a very good internal consistency (Cronbach's alpha 0.877). Factor analysis allowed us to sub-divide DYMUS in two sub-scales, 'dysphagia for solid' and 'dysphagia for liquid', both of them had a very good internal consistency (Cronbach's alpha 0.852 and 0.870 respectively). DYMUS demonstrated to be an easy and consistent tool to detect dysphagia and its main characteristics in MS. It can be used for preliminary selection of patients to submit to more specific instrumental analyses, and to direct toward programs for prevention of aspiration.

Single-agent epirubicin as primary chemotherapy in T2-T3, N0-N2, M0 breast carcinoma: 6-year follow-up.

OBJECTIVE: Single-agent epirubicin was tested as primary chemotherapy treatment in patients with early breast cancer >3 cm. METHODS: 100 women with locally advanced breast cancer >3 cm were treated with three cycles of single-agent epirubicin at a dose of 120 mg/m2. All patients showing tumor shrinkage to less than 3 cm were considered candidates for conservative surgery (quadrantectomy); in the remaining patients modified radical mastectomy was carried out. Postsurgical treatment consisted of CMF chemotherapy except for postmenopausal node-positive, estrogen-positive patients who were assigned to hormonal treatment with tamoxifen and postmenopausal node-negative, estrogen-positive ones who did not receive any treatment. RESULTS: Quadrantectomy was carried out in 71 patients. At the median follow-up time of 69 months, the relapse rate was 29.6% among patients who underwent quadrantectomy (21 out of 71) and 58.6% among patients who underwent modified radical mastectomy (17 out of 29). CONCLUSIONS: Single-agent chemotherapy with anthracyclines could appear to be an effective treatment in inducing a tumor downstaging in patients with early breast cancer >3 cm. This treatment can be administered outside clinical trials in patients who desire to preserve their body integrity. Further prospective, randomized trials are needed in order to validate and better define the role of epirubicin in the neoadjuvant strategy of breast cancer patients.

Validation of the Dutch Eating Behaviour Questionnaire parent version (DEBQ-P) in the Italian population: a screening tool to detect differences in eating behaviour among obese, overweight and normal-weight preadolescents.

OBJECTIVE: To validate the Dutch Eating Behaviour Questionnaire Parent version (DEBQ-P) in the Italian population and investigate the differences in eating behaviour among Italian normal-weight, overweight and obese preadolescents. DESIGN: A cross-sectional validation study. Participants were measured and the approved translation of the questionnaire was administered to their parents. SETTING: : Three school communities in the province of Bergamo, Northern Italy. SUBJECTS: A total of 312 preadolescents (mean age 12.9 y; s.d. 0.8, both sexes) from three secondary schools of the province of Bergamo, Northern Italy, and their parents were invited to participate to the study. Informed written consent was obtained from each subject and their parents. Students were measured and their parents filled in the approved translation of the DEBQ-P. Recruitment was opportunistic and school based. RESULTS: Factor and internal consistency analysis confirmed the factor structure of the DEBQ-P and the high internal consistency of its three scales. Variance analysis showed that eating behaviour of Italian normal-weight, overweight and obese preadolescents differs significantly only in regards to the 'restrained eating' scale (F 19.29, P < 0.001), with overweight and obese scoring higher. CONCLUSIONS: The DEBQ-P can be used for screening projects regarding eating behaviour in the Italian population. The association between restrained eating and weight status was confirmed for both sexes, but the relationship between external eating and emotional overeating and overweight requires further exploration.

Reliability of a dietary questionnaire on food habits, eating behaviour and nutritional knowledge of adolescents.

OBJECTIVE: To develop a dietary questionnaire on food habits, eating behaviour and nutrition knowledge of adolescents and to examine its reliability. DESIGN: A cross-sectional baseline survey. The questionnaire was self-administered to study participants twice with 7 days between each administration. SETTING: A school community in Pavia, Italy. SUBJECTS: A group of students (n=72, aged 14-17 y, both sexes) studying in a secondary school in the second year of the course were invited to compile a dietary questionnaire during school time. Informed written consent was obtained from each subject and their parents. Subjects were initially recruited for a nutrition intervention; recruitment was opportunistic and school based. STATISTICAL ANALYSES: Reliability was assessed using the Cronbach's alpha and the Pearson correlation coefficients. RESULTS: Cronbach's alpha ranges from a minimum of 0.55 to a maximum of 0.75, indicating that only two sections have a poor internal consistency. The Pearson correlation coefficients range from a minimum of 0.78 to a maximum of 0.88, indicating a very good temporal stability of the questionnaire. All the Pearson correlation coefficients are statistically significant with P<0.01. CONCLUSIONS: The present questionnaire has the potential to measure the effects of nutrition interventions on adolescents because of its stability in making comparisons over time. The instruments is low in cost and easy to administer and analyse; moreover, it could be modified appropriately to fit the needs of other populations as well.

Vinorelbine and carboplatin in inoperable non-small cell lung cancer: a monoinstitutional phase II study.

Chemotherapy regimens for patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) provide typically palliation or limited symptom-free survival. We investigated the efficacy, in terms of response rate and time to progression, of a combination chemotherapy containing carboplatin and vinorelbine as a first-line treatment for inoperable NSCLC. Fifty-two consecutive patients with advanced NSCLC were treated with carboplatin AUC 6 according to Calvert's formula on day 1, combined with vinorelbine, 25 mg/m(2) on days 1 and 8. Therapy was given every 3 weeks. The median age was 66 years (range, 40-80); ECOG performance status was 0 in 20, 1 in 25 and 2 in 7 patients. According to an intent-to-treat analysis, response rate (partial and complete responses) in 52 assessable patients was 18/52 (34.6%; 95% confidence interval, 22-47%). In addition, 16 patients (30.8%) had stable disease and 18/52 (34.6%; 95% CI, 22-47%) progressed while on treatment. Median time to progression and overall survival were 7, 5 and 12.3 months, respectively. Grade 3/4 granulocytopenia was observed in 18/8 patients (34.6/15.4%). Grade 3/4 nadirs generally lasted no more than 7 days, and no neutropenic fever was reported. The treatment was generally very well tolerated: grade 1 or 2 nausea and vomiting was observed in 12 and 4 patients, respectively, and grade 2 neuropathy in 5% of cases. Statistical analysis did not highlight any significant differences in clinical benefit (partial and complete responses and stable disease), time to progression, or grade 3-4 hematologic and non-hematological toxicity according to age (65 years). Carboplatin AUC 6 and vinorelbine was found to be an efficacious regimen as a first-line treatment for inoperable lung cancer patients and was also subjectively very well tolerated in aged patients. The regimen warrants further investigation in the emerging subgroup of aged patients in order to draw firm conclusions.

Evaluation of the efficacy of the Italian guidelines on COPD: a cluster randomized trial.

BACKGROUND: Chronic Obstructive Pulmonary Disease (COPD) is a profoundly disabling disease managed predominantly by General Practitioners (GPs). We planned this prospective trial to evaluate the applicability of Italian GP-directed guidelines in routine practice and whether adherence to them improves treatment efficacy, with respect to decreased exacerbations, hospital admissions, drug use, and out-patient appointments and improved quality of life (QoL). METHODS: In a cluster randomised trial, 22 GPs were randomly put into two groups: one group was asked to follow the guidelines (YES-GL), the other to continue normal clinical practice (NO-GL). These GPs enrolled 123 patients with COPD and followed them for one year. RESULTS: Patients managed by the YES-GL GPs had more outpatient appointments and specialist consultations and a higher probability of being classified as having severe COPD. The QoL was fairly low in both groups, and all other clinical outcomes taken into consideration, were not affected by application of the guidelines. CONCLUSION: The guidelines did not substantially alter the clinical evolution of COPD patients, even though some facets of management improved.

ECRHS screening questionnaire scoring: a methodological suggestion for asthma assessment. European Community Health Survey.

Univocal definition and classification of Asthma have always been a matter of discussion, and that is reflected in the difficulty of constructing a measure of pathology severity. The European Community Health Survey is a multinational survey designed to compare the prevalence of asthma in subjects, aged 20 to 44 years, in several European areas. In each participating center a sample of 3000 adults filled a self-administered screening questionnaire composed by 9 dichotomous items. Aim of the present study is to investigate unidimensionality of the ECRHS screening questionnaire and to determine and validate a scoring of asthma-like symptoms seriousness. Dimensionality and scoring was determined through a Homogeneity Analysis by Alternating Least Square; while scoring validation was assessed by a cross validation technique. This study found the existence of a sole dimension underlying the screening questionnaire; furthermore a scoring of asthma-like symptoms seriousness was determined with the indication of a cut-off in order to distinguish between asthma symptomatic and non symptomatic subjects.
