Smoking is a risk factor for thromboangiitis obliterans (TAO, Buerger’s disease) and arteriosclerosis, but there are few cases of coronary heart disease (CAD)-associated Buerger's disease. A literature search for articles in English, Spanish and French published between 1966 and 2012 on patients with coronary involvement and TAO revealed 12 patients. We describe an additional case with involvement of the central nervous system, myocardium and large-diameter proximal arteries. The main clinical manifestations in these 13 cases were lower limb claudication and acute thoracic pain. The histologic findings showed thrombosis with unbroken internal elastic lamina and intimal clusters of granulocytes; coronary angiography revealed predominant involvement of the left anterior descending and right coronary artery. Treatment included coronary bypass procedures, coronary angioplasty, smoking cessation, and anticoagulant therapy. A complete therapeutic response was observed in half the patients. This review of all published cases of TAO patients with coronary symptoms, together with our patient, demonstrates the rarity of this clinical association. Patients under age 40 with CAD but no prominent cardiovascular risk factors besides smoking should be evaluated for the presence of Buerger's disease.

Giant cell arteritis (GCA) is considered to be a T cell-dependent disease. Autoantibodies have not consistently been found in GCA. The exception is antiphospholipid antibodies (APLA), which were found in 30–80% of GCA cases. Recently, efforts have been made to seek autoantibodies in GCA using newer methods of detection: serological identification of antigens by recombinant cDNA expression cloning, and a proteomic approach. In these studies, lamin C (a nuclear envelope antigen) was recognized by antibodies in 32% of GCA sera and none of the controls. Other autoantigenic proteins were also identified: lamin A, vinculin (a cytoskeleton antigen), and annexin 5 (an endothelial protein). In a recent study, 92% of 36 patients with GCA and/or polymyalgia rheumatica (PMR) had autoantibodies to a human ferritin peptide (the heavy chain N-terminal); 89% had antibodies to bacterial ferritin peptide of Staphylococcus epidermidis. The significance of these findings needs to be studied further. GCA may be a part of the newly described ASIA syndrome (autoimmune syndrome induced by adjuvants). A recent study from Italy reported 10 cases of GCA/PMR within 3 months of influenza vaccination. These comprised 50% of all cases of GCA/PMR diagnosed during the 6 year period of the study. Another 11 cases of GCA following influenza vaccinations were reported. GCA pathogenesis involves all branches of the immune system, including antigen-presenting cells, T cells and B cells, and autoantibody formation is not uncommon. GCA etiology remains unknown, but may be associated with exposure to bacterial or viral antigens.

Background: Ethiopian immigration to Israel was initiated in 1981. Most immigrants were rural dwellers who migrated first to Addis Ababa or Gondar, where they waited for eligibility status from Israel to leave Ethiopia. Soon after arriving in Israel, all immigrants were offered screening tests for human immunodeficiency virus (HIV) and syphilis.
Objectives: To evaluate the association of age, gender, marital status and length of time spent in urban areas in Ethiopia with the prevalence of HIV and syphilis seropositivity.
Methods: All adult Ethiopian immigrants who arrived at the Jerusalem immigration center between 1999 and 2002 and consented to HIV and syphilis screening tests were interviewed.
Results: Altogether, 678 immigrants (51% females) were screened; 39 (5.8 %) were seropositive for HIV and 33 (4.9%) for syphilis. The length of time the immigrants spent in Ethiopian cities before leaving for Israel was significantly associated with HIV: odds ratio (OR) 2.76, 95% confidence interval (CI) 1.13–6.71, and syphilis seropositivity OR 3.87, 95%CI 1.56–9.62.
Conclusions: The length of transit time Ethiopian immigrants from rural areas spend in Ethiopian cities is significantly associated with HIV and syphilis seropositivity. Efforts should be made to shorten this time in order to reduce the risk of infection
