During acute phase, patients with KD have reduced global left ventricular S and SR which may be more sensitive indicators of myocardial inflammation. This study showed gradual improvements in left ventricular myocardial function during treatment for KD.

Despite being recognised much more frequently than in the past, renal involvement has not previously been regarded as a feature of Behcet's disease (BD). In this study we aimed to assess the frequency of renal involvement in BD by performing urinalyses of 674 consecutive BD patients; we also retrospectively evaluated the charts of 4212 BD patients for the incidence of glomerulonephritis (GN). Urinary abnormalities (proteinuria and/or haematuria) were present in 10.8%; and during a period of 23 years GN was detected by renal biopsy in seven (0.16%) BD patients. Two patients with GN were lost to follow-up; end-stage renal failure developed in only one patient, and she underwent renal transplantation. We were unable to determine any pathognomonic feature that was predictive of renal involvement. Although males tend to have a more serious clinical course of BD the incidences of urinary abnormalities and GN were similar in both sexes in our series. According to our results, we can conclude that urinary abnormalities are more frequent in BD; however, serious renal lesions develop in only very few of these patients.

Objectives The aim was to evaluate the role of tissue Doppler imaging (TDI) and speckle tracking echocardiography (STE), to identify myocardial dysfunction, and to evaluate myocardial segmental deformation in acute viral myocarditis. Methods Twenty‐one patients and twelve healthy children were studied prospectively. The TDI and STE were performed before and after treatment. The myocardial velocities (Sm, Em, and Am) and time intervals (isovolumic contraction, isovolumic relaxation, and ejection times [ET]) at interventricular septum (IVS), left, and right ventricular basal segments were examined by TDI. The left ventricular global longitudinal strain (LVGLS) and strain rate (LVGLSR), left ventricular global circumferential strain (LVGCS) and strain rate (LVGCSR), and right ventricular global longitudinal strain (RVGLS) and strain rate (RVGLSR) were examined by STE. Results Sm and Em at IVS and at LV, ET at IVS, ET at RV, ET at LV were significantly lower in patients before treatment than controls. LVGLS, LVGLSR, LVGCS, LVGCSR, RVGLS, RVGLSR were significantly decreased in patients before treatment than controls. There was significant improvement for LVGLS, LVGLSR, LVGCS, LVGCSR, and RVGLS in patients after treatment. Sm, Em, and Am at LV were significantly lower in patients before treatment than in patients after treatment. In spite of improvements, Sm, Em, and ET at IVS, LVGLS, LVGLSR, LVGCS, LVGCSR were significantly lower in patients after treatment than controls. Conclusions The TDI and STE were useful methods for detection of early myocardial dysfunction and evaluation of treatment outcomes in acute viral myocarditis.
