To report on the differential diagnosis of lyme arthritis and synovial hemangioma due to similar clinical and radiological signs and symptoms. A 15-year-old boy presented at the age of 9 with recurrent rather painless swelling of the right knee. Altogether four episodes lasting for 1-2 weeks each occurred over a period of 18 months before medical advice was sought. ⋯ To our knowledge, the differential diagnosis of lyme arthritis and synovial hemangioma has not yet been reported despite obvious clinical similarities. In conclusion, in children and adolescents synovial hemangioma has to be considered in differential diagnosis of recurrent knee swelling. Early diagnosis is important to prevent prolonged suffering from chronic joint swelling with probable joint damages, unnecessary treatment procedures and as well school and sports absenteeism.

In systemic sclerosis (SSc), major determinant of morbidity and mortality is pulmonary complication including pulmonary interstitial lung disease (ILD) and pulmonary arterial hypertension (PAH). In this study, the natural course of pulmonary involvement in SSc patients was investigated. This was a historical cohort study of SSc patients at a referral center for SSc in Iran between February 1998 and December 2007. ⋯ The difference was not significant in two subtypes when Cox regression model was used to identify the effect of other prognostic factors on pulmonary survival in patients. In the present study, clinical manifestations of two subtypes of disease were divergent at first; however they became convergent in late stages, and this was the same as results in previous studies. Echocardiography for evaluation of pulmonary hypertension and pulmonary function tests for early detection of ILD and PAH is recommended for SSc patients to detect early stages of pulmonary involvement before significant vascular and fibrotic changes occur.

Disseminated intravascular coagulation (DIC) may complicate a variety of disorders that contribute to mortality, particularly those related to bleeding. It is therefore very difficult to manage DIC in patients with known bleeding disorders. We treated a 62-year-old woman with idiopathic thrombocytopenic purpura (ITP) complicated with sepsis-induced DIC. ⋯ Based on these findings, the patient was diagnosed with sepsis-induced DIC due to urinary tract infection. Thrombocytopenia was refractory despite the use of antibiotics and platelet transfusion, but it was promptly improved in response to recombinant human soluble thrombomodulin (rTM). We suggest that rTM provides a new therapeutic strategy for DIC patients with high hemorrhagic risk.
