Ultrasonography (US) features of thyroid nodules can be helpful in identifying those most at risk for malignancy; these include marked hypoechogenicity, microcalcifications, irregular margins, and a taller-than-wide shape (nonparallel orientation). Some cystic change morphologically after simple aspiration percutaneous ethanol injection treatment. They show hypoechogenicity margins on the US di...

1. The size of the dose of the infecting material exerts an appreciable effect upon the duration of the incubation period in experimental syphilis of the rabbit. Other things being equal, the larger the dose the shorter is the incubation period. 2. The size of the inoculum was not found to exercise any marked effect upon the course of the disease as a whole. 3. In individual rabbits inoculated ...

Inflammatory pseudotumor (IPT) of the liver is a rare benign tumor of unknown origin, it has the appearance of a malignant tumor but has a benign histology and clinical course. We report a case of a 63-year-old man diagnosed of IPT of the liver and followed for 10 years. During the clinical course, he developed a secondary Budd-Chiari syndrome, with a successful response to a transjugular intra...

BACKGROUND AND PURPOSE Hemicraniectomy has been shown to be an effective treatment of life-threatening edema (LTE) in malignant middle cerebral artery infarction when performed early. Identifying patients who will develop LTE is therefore imperative. We hypothesize that autonomic shift toward sympathetic dominance may relate to LTE formation. We aimed to investigate the predictive potential of ...

BACKGROUND Differentiating between benign and malignant submucosal tumors is difficult. Moreover, the natural course of benign-appearing SMTs is not clearly elucidated. OBJECTIVES To evaluate the natural course of upper gastrointestinal SMTs by endoscopic endosonography. METHODS We followed 25 consecutive patients with small (< 40 mm) SMTs for a mean period of 19 months. Evaluation included...
