The features of infective endocarditis include both cardiac and non-cardiac manifestations. Neurologic complications are seen in up to 40% of patients with infective endocarditis and are the presenting symptom in a substantial percentage. We describe in detail the clinical scenarios of three patients admitted to our hospital, compare their characteristics and review the recent literature describing neurologic manifestations of infective endocarditis. Our patients demonstrate that infective endocarditis can develop without comorbidity or a valvular defect. Moreover, our patients were young and lacked the most common symptom of endocarditis: fever. The most common neurologic manifestations were focal neurologic deficits and confusion. We conclude that infective endocarditis should always be considered in patients presenting with new-onset neurologic complaints, especially in those without comorbidities or other risk factors. A prompt diagnosis should be reached and antibiotic treatment initiated as soon as possible.

Stem cell therapy has developed extensively in recent years, leading to several new clinical fields. The use of mesenchymal stromal cells sparks special interest, as it reveals the importance of the paracrine and immunomodulatory effects of these supporting cells, in disease and in cure. This review discusses our current understanding of the basic clinical principles of stem cell therapy and demonstrates the broad range of this treatment modality by examining two relatively new therapeutic niches – autoimmune and cardiac diseases.

Background: Familial Mediterranean fever is an autosomal recessive disease characterized by recurrent attacks of fever and serositis. The disease is caused by mutations in the MEFV gene, presumed to act as a down-regulator of inflammation within the polymorphonuclear cells.

Objectives: To present the results of 412 FMF patients genotyped for three MEFV mutations, M694V, V726A and E148Q.

Results: The most frequent mutation, M694V, was detected in 47% of the carrier chromosomes. This mutation, especially common among North African Jewish FMF[1] patients, was not found in any of the Ashkenazi (East European origin) patients. Overall, one of the three mutations was detected in 70% of the carrier chromosomes. M694V/M694V was the most common genotype (27%), followed by M694V/V726A (16%). The full genotype could be assessed in 57% of the patients, and one disease-causing mutation in an additional 26%. Only one patient with the E148Q/E148Q genotype was detected despite a high carrier rate for this mutation in the Jewish population, a finding consistent with a low penetrance of this genotype. The M694V/M694V genotype was observed in 15 patients with amyloidosis compared to 4 amyloidosis patients with other genotypes (P < 0.0001).

Conclusions: Because of low penetrance and as yet other undetermined reasons, mutation analysis of the most common MEFV mutations supports a clinical diagnosis in only about 60% of patients with definite FMF.
