Cyclosporin is an immunosuppressive drug used with increasing frequency in patients with diabetes mellitus both as experimental primary therapy for insulin-dependent diabetes mellitus and as therapy accompanying pancreatic transplantation. However, reports have appeared contending that cyclosporin causes glucose intolerance and inhibits pancreatic islet beta-cell function. Consequently, concern has been raised that the beneficial effects of immunosuppression may be offset by adverse metabolic effects of the drug. To address this issue, we examined intravenous glucose tolerance and pancreatic islet beta-cell function in a group of nondiabetic multiple sclerosis patients before and during a 2-yr course of cyclosporin or placebo therapy. Patients were randomly assigned to one of the two drug groups and followed in a double-blind manner. Basal levels of glucose, insulin, and C-peptide as well as glucose disappearance rates and pancreatic islet beta-cell function after stimulation with intravenous glucose and arginine were determined immediately before therapy and after 3 wk, 6 mo, 1 yr, and 2 yr of therapy. No abnormalities in these parameters were observed in the cyclosporin of the placebo-treated group. It appears that cyclosporin can be give in conventional doses for as long as 2 yr without encountering evidence for impaired glucose homeostasis. However, whether adverse effects will materialize over longer periods of drug use remains a question.

Cyclosporin or placebo was administered in a randomized, double-blind fashion to 13 patients with multiple sclerosis for 1 yr to determine whether cyclosporin adversely affects glucose homeostasis or beta-cell function. No significant differences were observed in fasting glucose, fasting insulin, intravenous glucose tolerance, or glucose-induced insulin secretion before treatment or at 3 wk, 6 mo, or 1 yr during treatment. Longer therapeutic trials with larger patient groups will be necessary to decide whether cyclosporin can be safely given for many years without risk of developing diabetes mellitus.

The patterns of migration and the genetic disorders occurring among North American Mennonites are reviewed, and inherited conditions recently recognized in a religious and genetic isolate, the Old Colony (Chortitza) Mennonites, are described. Old Colony Mennonites are of Dutch/German origin and descend from approximately 400 founding families who settled in the Old Colony, Chortitza (the Ukraine, USSR) in the late 1700s, and then migrated to Canada and Central and South America in the past century. We investigated over 6 generations of a Canadian Old Colony kindred in which there was extensive intermarriage, and in whom 28 individuals developed diabetes mellitus. Insulin-dependent diabetes mellitus (IDDM) occurred in 14 affected individuals in 10 closely related sibships; the 11 living IDDM patients were all concordant for the immunogenetic marker HLA-DR4. Fourteen close relatives had other disorders of carbohydrate metabolism, including gestational diabetes and non-insulin-dependent diabetes mellitus. Other close relatives had autoimmune diseases, including rheumatoid arthritis, hyper- and hypothyroidism, multiple sclerosis, and red cell aplasia. Other inherited diseases, including Alport syndrome, congenital defects, and inborn errors of metabolism were also found in the kindred. In the almost exclusively (99%) Old Colony Mennonite public health district in which the kindred was ascertained, there were multiple cases of Tourette syndrome, of malformations (including congenital heart defects and cleft lip +/- palate), and familial clusters of inborn errors of metabolism. We report this Old Colony (Chortitza) Mennonite isolate because 1) there are large familial aggregations of tissue-specific autoimmune diseases, malformations, inborn errors of metabolism, and of some other conditions whose genetic basis is still unknown; 2) there are multiple cases of rare genetic conditions, 3) we have established a computerized genealogic data base on over 1,000 kindred members as well as a cryopreserved lymphocyte/DNA bank on over 100 closely related individuals with various genetic conditions; and 4) this religious isolate, which extends across North, Central, and South America, offers an excellent opportunity for studying the epidemiology and molecular genetics of both common and rare inherited diseases.

The HLA region on the short arm of chromosome 6 contains a set of highly polymorphic loci responsible for regulating the immune response. Particular haplotypes, defined serologically, have been associated with a risk of developing certain autoimmune diseases such as insulin-dependent (juvenile-onset) diabetes mellitus, multiple sclerosis and rheumatoid arthritis. Recent developments in molecular biology have permitted an improved resolution of the locus and of the sequential arrangement of the susceptibility determinants on these haplotypes. Restriction fragment length polymorphisms have allowed subdivisions of serological haplotypes to be made. These correlate with disease susceptibility in some cases. Amplification of specific HLA class II alleles and nucleic acid sequencing have resulted in the identification of the structural determinants in the HLA that underlie some of these diseases.

In this retrospective study the case reports of 165 patients suffering from an abducens nerve palsy as the main presenting symptom were evaluated. The sixth nerve palsy was more frequent on the left (52%) than on the right hand side (38%), in 10% there was bilateral involvement. In 49 cases a vascular origin was suspected (29.7%), with diabetes mellitus as the most important risk factor (n = 35). Abducens palsies in inflammatory diseases (n = 32, 19.4%) were seen most often in multiple sclerosis (n = 11), viral meningoencephalitis (n = 5) and accompanying systemic viral infections (n = 5). Postvaccinal paresis was seldom (n = 1). Tumours (n = 18, 10.9%) causing sixth nerve paresis were metastases to the brain (n = 7), meningiomas (n = 3) and glioblastomas (n = 2). Nasopharyngeal carcinomas lead in 4 cases to an involvement of the abducens. Aneurysms causing sixth nerve palsy (n = 7, 4.2%) most frequent being located at the intracavernous region of the internal carotid artery (n = 4). In traumatic abducens paresis (n = 5, 3.1%) pathological findings of neuroradiological examinations are rare. In 48 patients (29.1%) diagnosis remained unclear, especially in young adults between the 20th and 40th year of age. Prognosis of abducens paresis is good in lesions of vascular and unknown origin; in these cases non-steroidal antiphlogistics are of benefit.

The membranes of mammalian cells are composed of an ordered array of lipids and proteins, the latter containing carbohydrate residues directed towards the exterior and important in the interaction of cells with each other and with external proteins. This external (plasma) membrane and other more simple membranes within the cell are damaged in all diseases which compromise the integrity of the cell. However, in many cases, chemical or functional changes in these membranes are central to the pathogenesis of the disease. These processes are illustrated, and a classification of membrane-related diseases is proposed. This includes: receptor-related diseases such as type II familial hypercholesterolaemia, Grave's disease, some lysosomal storage diseases and some forms of diabetes and obesity; structural instability as manifested by red cell abnormalities and multiple sclerosis; changes in lipid state as in muscular dystrophy and multiple sclerosis; altered permeability or transport as in cystic fibrosis, diseases associated with specific transport defects, and the action of many bacterial toxins, and abnormality of the cytoskeleton-membrane interface as in Chediak-Higashi disease and some diseases associated with red cell abnormalities. Different mechanisms can contribute to the membrane disorder in a single disease state and many of these are described to illustrate this diversity.

This paper presents epidemiological data on the prevalence of 26 common (i.e., having a lifetime prevalence of more than 1 per 10(4) individuals in the population) multifactorial diseases in Hungary and estimates of detriment associated with them. The detriment is expressed using 3 indicators, namely years of lost life (LL), potentially impaired life (PIL) and actually impaired life (AIL). The total prevalence of these diseases in Hungary has been estimated to be about 6500 per 10(4) individuals in the population. This estimate is in agreement with published data for other parts of the world. On the basis of clinical severity, these diseases have been split into 3 groups, namely (1) very severe (schizophrenia, multiple sclerosis, epilepsy, acute myocardial infarction and related conditions, and systemic lupus erythematosus); (2) moderately severe and/or episodal or seasonal (15 entities including Graves' disease, diabetes mellitus, gout, affective psychoses, essential hypertension, peptic ulcers, asthma, etc.); and (3) less severe than those in the first 2 groups (varicose veins, allergic rhinitis, atopic dermatitis, Scheuermann disease and adolescent idiopathic scoliosis). The essential clinical and genetic aspects of these diseases are briefly discussed. With the exception of epilepsy, none of the diseases included in our list causes mortality between ages 0 and 19. However, they are among the leading causes of death between ages 20 and 69 and thereafter. A sizeable proportion of those with essential hypertension, diabetes mellitus, rheumatoid arthritis, etc. survive to 70 years and beyond, as do those with gout, glaucoma, allergic rhinitis, psoriasis, etc. Overall, about 16% of all deaths that occur in Hungary every year (all age groups) can be attributed to these diseases. The mean number of years of PIL covers a wide range (about 20-40, 12-70 and 40-60 for groups 1, 2 and 3, respectively), the overall mean being about 24 years. However, the nature and degree of impairment and the impact on the life quality of those afflicted differ for the different diseases. Likewise, the mean number of years of AIL (for which the interval between the mean age at premature retirement and mean age at death was used as a rough index) also spans a wide range from 16 to 45, and the overall mean is about 20 years. At the population level, the diseases considered in this paper cause about 2700 years of LL, 96,000 years of PIL and about 5800 years of AIL per 10(4) individuals in the population. Relative to Mendelian diseases as a whole, these multifactorial diseases are associated with much greater detriment (LL: 1.4 X; PIL: 30 X and AIL: 3.9 X).

Anejaculation is a disorder that occurs infrequently in the general population, but it occurs in some cases of spinal cord injury and dissection of retroperitoneal lymph nodes for testicular cancer. It is associated with multiple sclerosis, transverse myelitis, and diabetes mellitus. Electroejaculation, which involves electrodes in a probe placed in the rectum, electrically stimulates emission of seminal fluid. Semen thus obtained can be used for artificial insemination if a patient and his spouse wish to become natural parents.

The usual high-contrast visual acuity chart is well known as the best indicator of central visual function. It has the limitation of only testing the high frequency, high-contrast sensitive cells in the visual system. Some conditions demonstrate a normal response on the standard visual acuity test, but abnormal results when testing visual fields or contrast-sensitivity function (CSF). A variety of diseases fall into this category (multiple sclerosis, diabetes mellitis, glaucoma, CNS tumors in the visual system, etc). The testing of CSF permits us not only to vary the size of the target (spatial frequency), but also to determine the contrast of the target first visible to the patient. Due to the time necessary to conduct the test and the important challenge of obtaining consistent subjective responses, contrast-sensitivity testing in children has been difficult. Recently, Regan has developed low-contrast visual acuity cards similar in format to those used in the Sheridan Gardiner test. Although they do not require literacy, correct responses can be immediately verified and the test can be carried out within a short period of time. These cards allow testing well within the child's limited attention span. In the future it may be possible to use this method of testing to detect CSF defects in amblyopia similar to those previously reported by Hess and others and to see how these defects are affected by standard treatment.

We investigated a large Old Colony (Chortitza) Mennonite kindred with branches across Canada. Six generations of the kindred were traced. There was intermarriage among numerous family members. Insulin-dependent diabetes mellitus (IDDM) was identified in 10 members; all 7 living patients were found to carry the immunogenetic marker HLA-DR4. Nine other close relatives had disorders of carbohydrate metabolism, including gestational diabetes mellitus and non-insulin-dependent diabetes mellitus progressing to insulin use. Ten other relatives had autoimmune diseases, including rheumatoid arthritis, hyperthyroidism, hypothyroidism and multiple sclerosis. Cases of Alport's syndrome, congenital malformations, inborn errors of metabolism and unusual malignant diseases were also found in the kindred. In the small Alberta community in which the kindred was ascertained there were people of Old Colony Mennonite descent with genetic conditions such as Gilles de la Tourette's syndrome and congenital malformations, including congenital heart disease. This kindred represents the largest reported familial aggregation of IDDM. This disease and other disorders of carbohydrate metabolism occur in the context of a strong familial predisposition to autoimmune disease. Study of this family may permit empiric testing of proposed models of inheritance of diseases of complex origin such as IDDM. We report this Old Colony (Chortitza) Mennonite community because it is one of the settlements populated by this religious and genetic isolate, which extends across Canada and Central and South America and affords opportunities for the study of both common and rare inherited diseases.
