One of the severe complications of Behçet's syndrome is pulmonary arterial involvement. The authors report a patient with Behçet's syndrome who had the complications of multiple pulmonary arterial aneurysms presenting with hemoptysis and right ventricular thrombus. He underwent emergency surgery because of failure of intensive immunotherapy and died 2 months after the surgery.

Radius, ulna, short bones (RUS), carpal (CARP) bone age (BA), tibial cortico-diaphyseal (C/D) ratio and trabecular aspect were assessed in 19 children with steroid dependent nephrotic syndrome and 15 age matched healthy children. Both RUS and CARP BA were significantly lower than in the controls. Trabecular aspect and tibial C/D ratio did not show any statistical significance. There was a positive correlation between HSDS and RUS BA delay (r = -0.476, p < 0.05); CARP BA delay and RUS BA delay (r = 0.563, p < 0.01) and RUS BA and CARP BA (r = 0.891, p < 0.001). In conclusion, RUS and CARP BA are both retarded and positively correlated in steroid dependent nephrotic children.
In this report, we present a patient with BD, amyloidosis and end-stage-renal-disease and discuss the literature on BD and amyloidosis. Forty-four patients with BD and amyloidosis are described in the literature. The type of amyloid fibrils were studied in 27 of this 44 patients and all were AA. The interval between the onset of first symptom of BD and the diagnosis of amyloidosis ranged from one to 27 years. This clinical observation and AA type amyloid fibrils in BD suggest that amyloidosis is secondary to inflammation. Behçet's disease should be considered in the differential diagnosis of AA amyloidosis.

Budd-Chiari syndrome (BCS) is a very infrequent complication of Behçet's syndrome. The authors report a young, male patient with Behçet's syndrome presenting with BCS. He underwent emergency surgery for thrombectomy but unfortunately died during the operation.
We studied 201 consecutive patients who received a relatively fixed dose of radioiodine for the treatment of hyperthyroidism between the years 1981-6. Patients with Graves' disease (170) were initially treated with a mean (SE) dose of 369 (10) MBq 131-I with a remission rate of 94% at 6 months and a cumulative relapse rate of 12% at one year and 21% at 5 years. The cumulative incidence of hypothyroidism was 26% at 3 months, 55% at 6 months, 61% at 1 year and 66% at 5 years. Patients with a uninodular goitre (10) were initially treated with a mean (SE) dose of 438 (85) MBq 131-I with a remission rate of 100% at 6 months, without relapse at 1 year but relapsing in 17% at 5 years. The cumulative incidence of hypothyroidism was 26% at 3 months, 30% at 6 months, 40% at 1 year and 40% at 5 years. Patients with a multinodular goitre (21) were initially treated with a mean (SE) dose of 613 (77) MBq 131-I with a remission rate of 79% at 6 months and a cumulative relapse rate of 26% at 1 year and 39% at 5 years. The cumulative incidence of hypothyroidism was 5% at 3 months, 14% at 6 months, 24% at 1 year and 24% at 5 years.
Behçet's disease is a multisystem disorder characterized by recurrent aphtous ulcers of mucosal membranes, skin lesions, and vasculitis. The prevalence of vascular involvement is about 25% and this is the leading cause of death in Behçet's disease. Jugular vein involvement is an unusual manifestation of Behçet's disease. Medical insertion of needles into veins or arteries can induce thrombosis or aneurysms. Thus, diagnostic studies or therapy can aggravate the disease and even be fatal. We report a patient with Behçet's disease and rare internal jugular vein thrombosis. We also demonstrate the ability of noninvasive magnetic resonance imaging and magnetic resonance angiography to aid in the diagnosis and evaluation of vascular involvement in Behçet's disease, without risking iatrogenic complications.
Insulin resistance is an important risk factor of cardiovascular disease. This study was performed to determine the effects of valsartan on insulin sensitivity in patients with primary hypertension. In this study, non-obese subjects with primary hypertension and a reference group of healthy subjects matched by age, sex and body mass index were evaluated; patients with any other causes of peripheral insulin resistance and hyperlipidaemia were excluded. The effect of valsartan on insulin resistance, assessed by homeostasis model assessment (HOMA-IR), fasting serum insulin levels, determined by radioimmunoassay, and fasting blood glucose concentrations, measured by the glucose oxidase method, were evaluated. All obtained data were evaluated by Pearson correlation analysis. Before valsartan treatment, the fasting serum insulin levels were significantly elevated in the 20 hypertensive patients with primary hypertension compared with the 20 subjects in the reference group (19.6 +/- 7.1 versus 8.7 +/- 1.9 microIU/ml). The fasting serum insulin levels correlated with HOMA-IR. Correlation analysis also showed a significant relationship between HOMA-IR and both systolic and diastolic blood pressures (r = 0.71 and r = 0.77, respectively). In our study, we showed that patients with primary hypertension have a decreased insulin sensitivity that was reflected in high serum fasting insulin levels. Anti-hypertensive treatment with valsartan increases insulin sensitivity.
Interleukin 2 (IL-2), a Th1 lymphocyte-derived cytokine, is thought to play an important role in the pathogenesis of type 2 diabetes and rheumatoid arthritis (RA). The aim of our study was to evaluate changes in serum IL-2 levels and their correlation with glucose metabolism abnormalities, such as insulin resistance, in patients with RA. Thirty-six subjects with varying degrees of disease activity and 20 healthy age-, sex- and body mass index-matched control individuals were evaluated. Patients with any causes of peripheral insulin resistance were excluded. After a 12-h overnight fast, fasting insulin levels, homeostatic model assessment-insulin resistance (HOMA-IR) estimated insulin sensitivity, and serum IL-2 levels were significantly higher in all patients with RA than in the control individuals. Fasting insulin, HOMA-IR scores and IL-2 levels were correlated in the RA group. This study showed that patients with RA have altered IL-2 regulation, and that there was a significant correlation between serum IL-2 levels and insulin sensitivity.
