Occupation, education, and Parkinson's disease: a case-control study in an Italian population.

Current epidemiologic data on the association between occupational exposures and Parkinson's disease (PD) are inconsistent. In a case-control study, we investigated the associations between occupation and PD and between education and PD. The cases (n = 62) were those identified in a prevalence survey (door-to-door, two-phase) of three Sicilian municipalities, as a November 1, 1987. We then randomly selected from the general population two controls for each case, matched for age ( +/- year), sex, and municipality (n = 124). Information on current and past occupations and education for cases and controls was obtained during the survey. Subjects who worked for most of their lives as farmers were not at increased risk of PD (OR = 0.6; 95% CI = 0.3-1.3). Neither were subjects who worked for most of their lives in other occupations (e.g., housewives, fishermen, factory workers, salesmen, craftsmen, clerks). PD was not associated with low education. Our findings suggest that farming, as a broad occupational category, does not play a major role in the causation of PD.

Prevalence of epilepsy. A door-to-door survey in the Sicilian community of Riposto.

In a door-to-door survey of common neurological disorders in Sicily (SNES Project), we administered a screening symptoms questionnaire and a brief neurological examination to detect epileptic patients. All of the subjects effectively resident in the community of Riposto on 1 November 1987 (prevalence day) were investigated (n = 9956). The subjects with a positive questionnaire or a previous diagnosis of epilepsy were extensively examined by a neurologist and then definitively classified for epilepsy by a panel of senior neurologists. The crude prevalence of active and non-active epilepsy was 3.21/1000; the prevalence of active epilepsy alone was 2.71/1000. Of the 27 active cases, sixteen were affected by generalized tonic-clonic seizures, four by absences and four by complex partial attacks. All except two were being treated with antiepileptic drugs, most with phenobarbital. Our prevalence rate is lower than that reported by most authors, but similar to the rates in other Sicilian communities.

Prevalence of lumbosacral radiculopathy in two Sicilian municipalities. Sicilian Neuro-Epidemiologic Study (SNES) Group.

OBJECTIVES: As part of a door-to-door survey of neurologic diseases, we investigated the prevalence of lumbosacral radiculopathy (LR) in two Sicilian municipalities (N = 14,540, as of November 1, 1987). MATERIAL & METHODS: During phase 1, we administered a brief screening instrument to subjects in the study population. In phase 2, study neurologists using specified diagnostic criteria investigated those subjects who screened positive. Our case finding was restricted to subjects who manifested symptoms of LR in the six months preceding the prevalence day. RESULTS: We found 143 subjects affected by LR (112 definite, 31 possible) yielding a crude prevalence of 9.8 cases per 1,000 population. Age-specific prevalence was generally higher in men; it increased to a peak at age 50-59 years and decreased steadily thereafter. At the peak, prevalence was higher in factory workers, housewives, and clerks compared to workers in other occupations. CONCLUSIONS: LR is a common neurologic disease in the general population.

Incidence and lifetime prevalence of Bell's palsy in two Sicilian municipalities. Sicilian Neuro-Epidemiologic Study (SNES) Group.

INTRODUCTION: In a door-to-door two-phase survey of common neurologic diseases conducted in two Sicilian municipalities, we investigated the incidence and the lifetime prevalence of Bell's palsy (BP). MATERIAL & METHODS: During phase I, we administered a screening instrument for facial palsy to 11,901 adult persons. During phase 2, study neurologists using specified diagnostic criteria evaluated those subjects who screened positive. RESULTS: We found 73 subjects who had experienced BP during their life. The lifetime prevalence as of November 1, 1987, was 642.8 cases per 100,000 population age 15 years and above. The prevalence increased with age and was similar in men and women. Eighteen episodes of BP occurred in the three years preceding the prevalence day. The average annual incidence rate was 52.8 new episodes per 100,000 population age 15 years and above. Incidence increased with age. CONCLUSION: Comparison with other incidence studies suggests some geographic variability.

Prevalence of stroke: a door-to-door survey in three Sicilian municipalities. Sicilian Neuroepidemiologic Study (SNES) Group.

As part of a door-to-door survey, we screened for stroke among the inhabitants of three Sicilian municipalities (n = 24,496 as of November 1, 1987). Neurologists then investigated those subjects suspected to have had a stroke. Diagnoses of first-ever strokes were based on specified criteria and were reviewed by an adjudication panel. We found 189 subjects who had experienced at least one completed stroke (180 definite, 9 possible); 15 strokes were hemorrhagic, 71 ischemic, and 103 uncertain. The prevalence (cases/100,000) was 771.6 in the total population and 1,893.6 in those aged 40 years or over. The prevalence increased steeply with age, was higher in men between 60 and 79 years, but was higher in women thereafter. Age-specific figures were similar in the three study municipalities. Although all first-ever strokes had been previously diagnosed, 40% of the subjects had not been hospitalized for this condition.

Attrition and use of proxy respondents and auxiliary information in the Sicilian Neuroepidemiologic Study.

Two-phase prevalence surveys with screening (phase 1) and examination (phase 2) are useful for some chronic diseases. Attrition, which may bias estimates, occurs in either phase because some eligible subjects die before contact, some refuse to cooperate, some are incapacitated, and some are unreachable. This investigation relates to a survey of neurologic diseases conducted in three municipalities of Sicily (prevalence date, November 1, 1987) and considers the attrition experienced and the use of proxy respondents in phase 1 and auxiliary information in phase 2 to offset, in part, this attrition. Regarding case finding, the salvage effort was more productive for decreased and incapacitated subjects. The age, sex, and household size of the subject were related to phase 1 attrition, but only age was related for all four attrition groups--deceased, refusing, incapacitated, and unreachable subjects. On the basis of information from proxy respondents, the educational levels of refusing and unreachable subjects were compared with those of subjects screened directly. Refusing subjects were less educated, and unreachable subjects were more educated. The proxy respondent performance, as indicated by "don't know" responses, was better with screening items concerning facial paralysis and mouth drooping (and not limb sensory abnormalities or impaired consciousness), better with younger subjects, and worse with refusing or incapacitated subjects.

Risk factors for cerebral glioma in adults: a case-control study in an Italian population.

A case-control study on risk factors for cerebral tumors was conducted on an adult Italian population by the four Neurosurgical Departments of the Veneto Region, i.e. Padua, Treviso, Verona and Vicenza. The study recruited 195 cases of histologically-confirmed cerebral glioma. One hospital control was selected for each case. Cases and controls were matched for age, sex, data of hospitalization and residence. Information on both cases and controls was obtained from a relative. Uninvolved interviewers administered a structured questionnaire including items on the subject's education, occupation, lifestyle, medical history, exposure to radiation for diagnosis or therapy, head trauma and blood group and the medical history of family members. The series of cerebral tumors was first considered as an indistinct set: none of the risk factors examined showed a statistically significant association. A positive association was found with blood group A (OR = 6) when low-grade astrocytomas (n = 41) were considered separately. As for the malignant astrocytomas (n = 132), there was a suggestive but not statistically significant association with the presence of CNS tumors among first- and second-degree relatives (OR = 7.0). On the whole, this study yielded no clear and meaningful association for the various risk factors analyzed.

Prevalence of essential tremor: a door-to-door survey in Terrasini, Sicily. Sicilian Neuro-Epidemiologic Study Group.

As part of a door-to-door neuroepidemiologic survey, we investigated the frequency and distribution of essential tremor (ET) in a Sicilian municipality. During phase 1, we administered a screening instrument for tremor to 7,653 persons residing in Terrasini (Palermo province). During phase 2, neurologists evaluated those subjects who had screened positive. The diagnoses, based on specified clinical criteria, were reviewed to increase reliability across neurologists. We found 31 subjects affected by ET (17 men, 14 women); 11 patients (35.5%) reported a familial aggregation. The prevalence of ET as of November 1, 1987, was 405.1 per 100,000 for the total population, and 1,074.9 per 100,000 for those 40 years old or older. The prevalence increased with advancing age for both sexes and was slightly but consistently higher in men. Comparison with other studies suggests striking geographic variation, which may reflect genetic differences.

Prevalence of diabetic neuropathy with somatic symptoms: a door-to-door survey in two Sicilian municipalities. Sicilian Neuro-Epidemiologic Study (SNES) Group.

In a door-to-door survey conducted in two municipalities of Sicily, we ascertained the prevalence of diabetic neuropathy. Our case-finding was restricted to subjects with somatic symptoms. During phase 1, we administered a screening instrument for peripheral neuropathy to 14,540 persons residing in Santa Teresa di Riva (Messina Province) and Terrasini (Palermo Province). During phase 2, neurologists evaluated those subjects who had screened positive. Diagnoses were based on clinical criteria only, and were reviewed by an adjudication panel. We found 39 persons (27 women, 12 men) affected by diabetic neuropathy. The crude prevalence, as of November 1, 1987, was 268.2 cases per 100,000 population. The prevalence increased with advancing age for both sexes and was consistently higher in women. The most common type was distal symmetric polyneuropathy. The median time between diagnosis of diabetes mellitus and onset of diabetic neuropathy was 8 years, and almost all identified persons with diabetic neuropathy were under treatment for diabetes mellitus.

Validating screening instruments for neuroepidemiologic surveys: experience in Sicily. Sicilian Neuro-Epidemiologic Study (SNES) Group.

In a hospital setting in Sicily, we assessed a screening instrument developed for a prevalence survey of parkinsonism, peripheral neuropathies, stroke, and epilepsy. The subjects consisted of (1) hospital patients with any of the above-mentioned diseases, to investigate sensitivity; and (2) hospital visitors free of all these diseases, to investigate specificity. The standard for comparison was a clinical evaluation based on specified criteria. Trained interviewers administered the screening instrument, asking subjects to answer symptom questions and to perform simple physical tasks. For the questions and tasks together, the sensitivity estimates were 100% for parkinsonism (n = 21), 96% for peripheral neuropathies (n = 22), 96% for stroke (n = 22), and 96% for epilepsy (n = 22), while the specificity estimate was 86% (n = 21). Analogous estimates were computed for the set of questions, for the set of tasks, and for each question and task individually. Despite limitations in our approach, we concluded that the screening instrument would be adequate for its intended use.

Prevalence of Parkinson's disease and other types of parkinsonism: a door-to-door survey in three Sicilian municipalities. The Sicilian Neuro-Epidemiologic Study (SNES) Group.

We investigated the prevalence of Parkinson's disease and other types of parkinsonism in a Sicilian population using a door-to-door two-phase approach. This design called for the administration of a brief screening instrument to all subjects who, on November 1, 1987, were residents of Terrasini (Palermo Province), Santa Teresa di Riva (Messina Province), and Riposto (Catania Province), Sicily (N = 24,496). Study neurologists using specified diagnostic criteria extensively investigated those subjects who screened positive. We found 63 subjects affected by Parkinson's disease, 21 with secondary parkinsonism, and seven with unspecified parkinsonism. The crude prevalence per 100,000 population was 371.5 for all types of parkinsonism and 257.2 for Parkinson's disease; for both entities, prevalence increased steeply with age and showed an inconsistent sex pattern. Our prevalence figures for Parkinson's disease are higher than those previously reported in Italy or elsewhere, which may be due, in part, to more complete case-ascertainment.

Haemangioma of the Zygoma. Report of two cases with a review of the literature.

Zygomatic haemangioma is a rare benign neoplasm occurring most frequently in adult females. The authors, after reviewing the available literature, report two cases which presented with a swelling of the zygoma. Resection of the neoplasm, immediate reconstruction with cranial bone grafts and internal rigid fixation was the treatment of choice. Results two years after surgery are presented.

Door-to-door prevalence survey of neurological diseases in a Sicilian population. Background and methods. The Sicilian Neuro-Epidemiologic Study (SNES) Group.

In three municipalities of Sicily, a prevalence survey of major neurological diseases was conducted door-to-door using screening and examination to find cases. This was the first large-scale neuroepidemiologic survey of that type undertaken in Italy: 24,496 persons were screened yielding 1,538 positives, of whom 1,408 were examined directly by neurologists and 110 were evaluated on the basis of existing medical documentation. In the article, we provide (1) a description of the population investigated and the survey methods employed; (2) details of the cooperation and the attrition experienced in the survey; and (3) age and sex tallies for the study population, including some on education level and occupation.

Osteoma of the frontoethmoidal sinuses: craniofacial resection and reconstructive strategy.

Frontoethmoidal involvement by benign tumors may lead to aesthetic and functional sequelae. The key for removal of such lesions is a proper planned craniofacial approach based on the preoperative evaluation. If total extirpation requires resection of part of the forehead or orbit, immediate reconstruction is mandatory. In recent years, craniofacial techniques and strategies have become popular. Among these are the use of split cranial bone, rotation of skull bones, the use of galeal-pericranial flaps, and the introduction of internal rigid fixation. We present a case of frontoethmoidal osteoma treated with a combined craniofacial approach. For the reconstruction, modern principles of craniofacial surgery have been applied.

Dry chemistry thin film immunoassay.

The authors report the development of a novel thin film multilayer immunoassay technology. The technology is applied to therapeutic drug monitoring and thyroid hormone testing in serum or plasma and can be extended to assays of other low molecular weight analytes. The assay detection range spans five orders of magnitude, from 1 x 10(-3) to 1 x 10(-8) M. The assay element comprises of multilayer coated chip, containing the active reagents in an agarose matrix and a plastic module serving both as a holder and a spreader. The assays are in the fluorescent competitive immunoassay format of the ligand displacement mode and are performed on an automated instrument with random access capability. The assays are fast and reliable and gave very good agreement when compared to reference methods.

Prevalence survey of major neurological disorders in Sicily. Results of a pilot study.

A pilot study on the prevalence of neurological disorders in Sicily was carried out with a protocol never previously used in Italy. A screening questionnaire was administered to 1,601 subjects of a community, designed to identify patients with cerebrovascular diseases, epilepsy, extrapyramidal syndromes, peripheral neuropathies, migraine and intracranial neoplasms. Of 262 subjects who were identified as likely to be suffering from neurological illness, 248 (94.6%) were examined by a neurologist. Of these, 8.9% were found to be normal, 46.8% were suffering from non-neurological diseases, 44.3% had one or more neurological diseases (prevalence of 6.8%). This pilot study proved to be a good starting-point for a future major survey.

Neuroepidemiological survey on Sicilian population. A feasibility study.

This research was designed as a pilot study in order to determine the feasibility and the reliability of a major door-to-door neuroepidemiological survey to be performed in the near future in 3 Sicilian towns with a total population of 30,000 inhabitants. 1,601 subjects were investigated by means of a questionnaire for the prevalence of stroke, epilepsy, parkinsonian syndromes, peripheral neuropathies, intracranial neoplasm and migraine. This preliminary study proved to be a good starting point, but some difficulties were identified in the questionnaire, in data collecting instruments and in diagnostic criteria.
