Dietary habits and multiple sclerosis. A retrospective study in Ferrara, Italy.

In a retrospective case-control study of multiple sclerosis (MS), set up with the aim of verifying the role of environmental factors in pathogenesis, we included a section on dietary habits. We compared the frequency and pattern of food consumption by cases and controls. We found an association between. MS and high consumption of bread and "pasta", butter and lard, legume soup, horse flesh, coffee and tea in the period from infancy to adolescence. A different pattern of consumption of eggs, wine and mineral water between cases and controls was found during adulthood. Our results support, at least partially, the data already reported in the international literature on an association between certain dietary factors and MS. Some foods consumed at certain "critical" ages could play a causal role in the onset of MS.

Multiple sclerosis: does epidemiology contribute to providing etiological clues?

The epidemiological approach has undoubtedly contributed to our knowledge of Multiple Sclerosis (MS) by providing some etiological hypotheses in spite of the fact that a definitive basis for the conclusive resolution of its enigma is still lacking. Epidemiological studies have indicated that MS has an uneven geographical distribution and a changing incidence over time at least in several areas of the world: this suggests an etiological role of both genetic and environmental factors. The racial difference in disease risk, the results of familial and twin studies as well as the association between MS and some HLA markers, support the great importance of genetic factors. On the other hand, the evidence of temporal trends and the data from migrant studies seem to underline the etiological contribution of environmental factors. In the light of these results much of the present views have emerged interpreting the disease as caused by multiple factors acting at a susceptible age in genetically predisposed subjects.

Retinal periphlebitis in multiple sclerosis: a marker of disease activity?

This study was performed in order to verify the prevalence of retinal periphlebitis and other ocular changes in a well-defined population of multiple sclerosis (MS) patients, and to correlate the presence of these features with some clinical variables which characterize the disease. 110 MS-affected subjects were submitted to a standard ophthalmologic examination including a biomicroscopical evaluation of the fundus oculi. The prevalence of retinal sheathing in MS patients was found to be nearly 36%. It is significantly higher in patients evaluated in an active phase of the disease than in those examined in a stationary phase.

Mortality study on multiple sclerosis in the province of Ferrara, northern Italy, 1968 through 1989.

A mortality study on Multiple Sclerosis (MS) was carried out in the province of Ferrara, Northern Italy, over the years from 1968 to 1989 (mean population 382,379 inhabitants) to outline the temporal trend of the disease in the residing population that can be regarded as a representative sample of the caucasians of Northern Italy. Given the difficulties in performing retrospective incidence studies over long time periods, the mortality rate was used as an indirect indicator of MS occurrence. Through a review of mortality tabulations with 340-345 ICD code and an intensive survey of all the MS cases, with successive check of the deceased ones at the general register offices of the study area communes, 56 MS patients who had lived and died in the province of Ferrara in the period 1968-1989 were selected with an average crude death rate of 0.67 per 100,000 per year (95% confidence interval: 0.51-0.87), 0.55 per 100,000 if adjusted to the Italian population. The death rate was stable over the considered time period with only a slight but insignificant increase in the last years of the survey. No differences were found among the rates from the 5 Local Health Units (USLs) in which the study territory is subdivided. The highest age-specific death rates were in the fifth and sixth decade of life and the average duration was 21.17 +/- 11.05 years. The results are consistent with a relatively stable MS risk in the population of the province of Ferrara and a homogeneous occurrence of the disease in the study territory.

Parkinson's disease in Ferrara, Italy, 1967 through 1987.

Epidemiological surveys on Parkinson's disease that have been carried out in different parts of the world have suggested that the disease is uniformly distributed in white populations. The position with regard to the Mediterranean peoples is still controversial, because of the large variation of the frequencies observed in the different areas that have been investigated. We therefore studied the frequency of Parkinson's disease in the Local Health Service of Ferrara, northeastern Italy (mean population, 187,000). Based on 394 patients, the mean incidence per year for the period from 1967 through 1987 was 10.01/100,000. The incidence rate of Parkinson's disease among cases with early onset was found to be statistically higher in rural areas as compared with urban ones (6.32/100,000 vs 3.11/100,000). Moreover, the study revealed a significantly higher incidence rate among agricultural workers (20.6/100,000). These results would seem to give further support to the hypothesis of a possible causal role of environmental factors that are mainly linked to agriculture, most likely due to the continual exposure to toxic agents in this area. However, further studies, which are not exclusively epidemiological, are necessary before any conclusions may be drawn, because many confounding variables may account for the results from surveys of this type.

Incidence of the Guillain-Barré syndrome in Ferrara, northern Italy, 1981-1987.

The few incidence estimates on Guillain-Barré syndrome (GBS) in Italy indicate rates lower than the values provided by other previous non-Italian population-based studies. The latter range from 0.6 to 1.9 cases per 100,000 population per year. To verify whether Italy may be considered a low-risk area for GBS we studied the incidence of the disease in Local Health Unit No. 31 (USL 31) of Ferrara, Northern Italy (mean population 180,701 inhabitants) for the years 1981-1987. The annual incidence rates were stable during this period with an average incidence of 1.26 cases per 100,000 population per year. No significant difference was found for urban or rural residence and there was no significant seasonal clustering. In 37.5% of the series an antecedent infection was recorded within 4 weeks before GBS onset. The survey seems to support the hypothesis of a homogeneous distribution of GBS in space and time and does not support the notion that GBS is less common in Italy than elsewhere.

Ganglioside therapy and Guillain-Barré syndrome. A historical cohort study in Ferrara, Italy, fails to demonstrate an association.

We investigated an alleged association between ganglioside therapy and the risk of developing the Guillain-Barré syndrome (GBS) in a historical cohort study. Using official medical records of the Local Health Unit No. 31 of Ferrara Province, northern Italy, we linked data on sales of gangliosides with information regarding hospital admissions and discharge diagnoses between January 1, 1988, and May 31, 1990. The number of incidence cases of GBS observed within 30 days of gangliosides administration in a cohort of 13,373 treated subjects (0.0 cases) was not significantly different from that expected in the general population (0.014). Our study suggests that patients receiving gangliosides are not at increased risk of developing GBS. However, because of sample size limitations, these findings should be confirmed in a larger cohort study.

Epidemiology of Parkinson's disease in Italy. A descriptive survey in the U.S.L. of Cento, province of Ferrara, Emilia-Romagna.

In order to verify the epidemiology of Parkinson's disease in northern-Italy, we carried out a descriptive study in the Local Health Service No. 30 of Cento, Emilia-Romagna. Based on 73 accepted cases, the prevalence rate on December 31, 1987, was 190.3 per 100,000 population. No significant difference was reported between the two sexes. The highest rates were observed in the age groups over 60 years. Our data indicate that the risk of Parkinson's disease in northern-Italy is similar to that observed in other Caucasian populations.

Primary CNS lymphoma in AIDS. A clinical and pathological case report.

A case is reported of a primary central nervous system lymphoma in a heterosexual patient affected by acquired immunodeficiency syndrome. Because of the rarity and the aggressive diagnostic procedures, pre-mortem diagnosis is seldom established. This radiosensitive tumor, however, often contains monoclonal immunoglobulin productive cells and shows, at CT-scan, a multicentric arrangement. On this basis, a careful analysis of the cerebrospinal fluid and CT-scan may offer a possible mean of earlier diagnosis and improve the survival of these patients.

HLA antigens and multiple sclerosis in the Province of Ferrara, northern-Italy: a community-based study.

The association between Multiple Sclerosis (MS) and DR2 HLA antigen is well known in Caucasoids. In the past few years a significant correlation has been found between DQwl and MS in North-East Scotland and in several other countries. In previous HLA studies in Italian MS patients, a lack of any association or an increased frequency of DR2 have been observed; however, the results of most Italian surveys derive from heterogeneous sample of affected individuals. This study was carried out in a homogeneous population of patients living in and originating from the province of Ferrara, Northern-Italy. Among the prevalence cases, 116, indigenous, unrelated patients, were typed for HLA-A-B, -DR and DQ antigens. The comparisons with 185 healthy individuals, originating from the same area, revealed an increased prevalence of DR2 antigen in Ferrara MS patients. This antigen does not appear to be related to the clinical variables of the disease.

[The combined use of instrumental and laboratory examinations in multiple sclerosis: is the diagnostic facilitation real?].

Spatial-temporal dissemination of neurological signs is an essential criterion for establishing a definite diagnosis of Multiple Sclerosis (MS). Unfortunately, we often observe patients who present a history consistent with MS but without objectivity indicating the presence of at least two or more distinct lesions of Central Nervous System (CNS). In recent years, many Authors have emphasized the use of Multimodal Evoked Responses (MER), Cerebrospinal Fluid (CSF) analysis for the research of Oligoclonal Bands (OB), and Magnetic Resonance Imaging (MRI) as highly sensitive techniques for demonstrating the spreading of the lesions. This study, carried out to evaluate whether the combined use of these three methods would increase the diagnostic MS sensitivity, comprises 62 patients classified in Definite (n = 24). Probable (n = 18) and Possible (n = 20) MS according to the clinical criteria of McAlpine. All our cases fulfilled a complete ER evaluation (VER, SER, BAER), a paired CSF and serum Isoelectric focusing (IEF) and a cerebral MRI. Moreover, IgG Index was also estimated. CSF IEF was the most sensitive test in Definite (91.7%) and Possible (80.0%) MS, nearly followed by MRI (87.5% and 45.0% respectively). VER (87.5% and 60.0%) and SER (87.5% and 65.0%). On the contrary, MRI showed the higher sensitivity in Probable MS (94.4%). The course of the disease influenced only SER and VER in all diagnostic group, while the duration correlated positively with BAER and VER. Only VER and BAER, finally, supplied additional information about the not revealed clinically or by MRI CNS disorders. Thus, our data further emphasize the value of combining these laboratory tests for establishing an early and more accurate diagnosis of MS.
