A 46-year-old male patient diagnosed with ankylosing spondylitis presented to our polyclinic with complaints of pain, swelling, and limitation in joint mobility in both ankles and erythema nodosum skin lesions in both pretibial sites. The sacroiliac joint graphy and the MRI taken revealed active and chronic sacroiliitis. On the thorax CT, multiple mediastinal and hilar lymphadenopathies were re...

he coexistence of thyroid and parathyroid diseases is not rare. In the review of the recent literature, 25% of the patients with primary hyperparathyroidism (PHPT) had significant associated thyroid diseases including carcinoma in an Australian series.1 Regal et al,2 reported a high prevalence of unsuspected varieties of thyroid disease occurring mainly in postmenopausal women in patients with ...

prolapsed mitral valve syndrome is a common, benign disorder with prevalence of %0.3-6 in population. this syndrome also is known as barlows syndrome and flaapy mitral valve syndrome. prolapsed mitral valve is the dropping of one or two mitral valve leaflet(s) into the left atrium during ventricular systole. this malformation leads to incomplete closing of mitral valve and regurgitates the bloo...

Limited finger joint mobility was assessed in 112 diabetic children, in their first-degree relatives, and in 50 unrelated non-diabetic children. In 42% of the diabetic children there was limited joint mobility, but 14% of them had more severe involvement. Limited joint mobility was correlated with increasing age, early presentation, and longer duration of diabetes. First-degree relatives of aff...

A 9-year-old girl, in whom MAS developed, was admitted to our Hospital in Tehran, Iran. She suffered from high grade fever and rash followed by multiple joint swelling months afterwards.

We present a new mechanical design for a compact three degrees-of-freedom joint mechanism. This joint design is ideal for use in robotic devices, especially hyper-redundant or snake-like robots. This joint exhibits an unprecedented range of motion: the origin of a coordinate frame attached to the output link of the joint can move on a spherical cone whose apex angle is 120 and this coordinate f...
