Morvan's syndrome associated with antibodies to multiple components of the voltage-gated potassium channel complex.
We describe a patient presenting with a combination of muscle fasciculations, paresthesias, hyperhidrosis, as well as insomnia, agitation and confusion. He went on to develop psychosis and respiratory failure requiring intensive care. Electromyography confirmed the presence of neuromyotonia and CSF showed mild pleocytosis. Routine testing for voltage-gated potassium channel complex (VGKC-complex) antibodies was highly positive, confirming the clinical diagnosis of Morvan's syndrome. The patient improved after treatment with intravenous immunoglobulin and methylprednisolone. Further investigation of the antigenic targets using immunohistochemistry and cell-based assays revealed that he had autoantibodies targeting Lgi1, Caspr2 and Contactin-2/Tag-1, all proteins known to be complexed with VGKC in peripheral nerves and CNS. This is the first case of Morvan's syndrome from Cyprus and illustrates the clinical features as well as the emerging complexity of antigenic targets involved in the pathogenesis
The occurrence of encephalomyocarditis virus (EMCV) in European pigs from 1990 to 2001
The occurrence of encephalomyocarditis virus (EMCV) among domestic pigs and wild boar in several European countries is described and discussed. From 1990 to 2001 clinical outbreaks were analysed and serum samples, partly from existing screening programmes, were tested for antibodies against EMCV. Most clinical EMCV outbreaks were reported in Belgium (320), followed by Italy (110), Greece (15) and Cyprus (6). The outbreaks appeared to be clustered in,endemic areas' with an increase in outbreaks during the autumn and winter months. The within-herd seroprevalence measured in clinically affected pig farms varied considerably among farms (2.87%), with age (0.84%) and by country. Data from farms with no clinical disease showed that subclinical infection with EMCV was found both within (seroprevalence 6.62%) and outside (up to 17%) the endemic areas of the clinically affected countries as well as in the non-clinically affected countries Austria and France (3-5.4%). Among wild boar, the seroprevalence varied between 0.6 and 10.8%, and a study in Belgium found a prevalence of virus infection of 3.3%

Epidemiological study of Q fever in humans, ruminant animals, and ticks in Cyprus using a geographical information system
A cross-sectional study of Q fever was conducted in a representative sample of the human and animal population in Cyprus in order to assess the seroprevalence of Q fever and the prevalence of related risk factors. A total of 583 human and 974 ruminant animal serum samples were collected and tested for the detection of antibodies against Coxiella burnetii phase II antigen using an indirect immunofluorescent assay. One hundred forty-one ticks were collected from the infested animals examined; the polymerase chain reaction and the shell-vial technique were used to detect and isolate C. burnetii. Standardized questionnaires were used to obtain information concerning inhabitants and their animals. A geographical information system was used to identify high-risk regions. The prevalence of IgG antibodies against C. burnetii phase II antigen was estimated at 52.7% for humans, 48.2% for goats, 18.9% for sheep, and 24% for bovines. C. burnetii was detected in 11 (7.8%) ticks. Using the geographical information system, two villages were identified as high-risk regions on the basis of high seroprevalence rates of IgG antibodies in humans and animals. Risk factors related to Q fever seropositivity were identified by logistic regression analysis and included age, residence, occupation, use of manure in the garden, ownership of animals (especially goats), and the presence of tick-infested or aborting animals. Q fever poses an occupational hazard to humans living in close contact with sheep and/or goats. In parallel, ticks should be considered an important aspect in the epidemiology of Q fever and should be further studied to better elucidate their role
