Dural Venous Sinus Thrombosis: A Rare Cause of Intracranial Hemorrhage.

Dural venous sinus thrombosis, a subset of cerebral venous thrombosis, is an important pathology due to its significant morbidity and mortality. This process has an annual incidence of three to five cases per million adults. Although copious predisposing factors exist, the core principles revolve around Virchow's triad: venous stasis, hypercoagulability, and vascular endothelial damage.

Fusion FDG-PET/MRI Evidence to Support Diagnosis of Frontotemporal Dementia-Related Primary Progressive Aphasia.

A 61-year-old right-handed man presented for cognitive neurological evaluation with word-finding difficulty, impaired word retrieval, impaired repetition of phrases, and stammering. Brain MRI and FDG-PET/CT were performed as initial imaging workup. Further FDG PET/MRI brain images were obtained through software fusion and revealed regional cortical atrophy with corresponding hypometabolic activity involving the posterior aspects of the left middle and inferior temporal gyri.

Randomized clinical trial of cutting balloon angioplasty versus high-pressure balloon angioplasty in hemodialysis arteriovenous fistula stenoses resistant to conventional balloon angioplasty.

Purpose: To compare the efficacy and safety of cutting balloon angioplasty (CBA) versus high-pressure balloon angioplasty (HPBA) for the treatment of hemodialysis autogenous fistula stenoses resistant to conventional percutaneous transluminal angioplasty (PTA).

Materials And Methods: In a prospective, randomized clinical trial involving patients with dysfunctional, stenotic hemodialysis arteriovenous fistulas (AVFs), patients were randomized to receive CBA or HPBA if conventional PTA had suboptimal results (ie, residual stenosis > 30%). A total of 516 patients consented to participate in the study from October 2008 to September 2011, 85% of whom (n = 439) had technically successful conventional PTA.

Clinico-laboratory characteristics of diabetic keto acidosis in adults in a tertiary hospital in Saudi Arabia.

Objective: The present study is undertaken to evaluate the magnitude of DKA in Saudi population with specific emphasis on clinical laboratory characteristics over 20 years.

Material And Methods: A prospective analysis of hospital records of 240 episodes of DKA requiring inpatient admission from December 1985 to December 2005 in adult patients in a tertiary hospital was performed. Besides the demographic data of the patients, the clinico-laboratory parameters relevant to the diabetes and DKA status were thoroughly reviewed.

Characterization of molecular and structural determinants of selective estrogen receptor downregulators.

Antiestrogens used for breast cancer therapy can be categorized into two classes that differ in their effect on estrogen receptor (ER) alpha stability. The selective estrogen receptor modulators (SERMs) stabilize ER alpha and the selective estrogen receptor downregulators (SERDs) cause a decrease in cellular ER alpha levels. A clinically relevant antiestrogen, GW7604, appears to work through a SERD-like mechanism, despite sharing the same molecular scaffold as 4-hydroxytamoxifen, a SERM.
