Incidence of Symptomatic Venous Thromboembolisms in Stroke Patients.

Venous thromboembolism (VTE) is a common but preventable complication observed in critically ill patients. Deep vein thrombosis (DVT) is the most common type of VTE, with clinical significance based on location and symptoms. There is an increased incidence of DVT and pulmonary embolism (PE) in ischemic stroke patients using unfractionated heparin (UFH) for VTE prophylaxis compared with those using enoxaparin.

Characterization of a Dual Nonlinear Helmholtz Resonator.

Resonant elements can generate small amounts of energy that make them pertinent for feeding miniaturized accelerometers with the energy needed. Suitable oscillator candidates are Helmholtz resonators, which have been, for a long time, analyzed and designed within the context of linear vibration. This study focuses on extracting nonlinear characteristics of a dual Helmholtz resonator (HR), with a neck-cavity-neck-cavity configuration, mounted on an acoustic waveguide with harmonically oscillating pressure.

Perceived core procedural skills for Nebraska family physicians.

We conducted a mail survey of 287 practicing family physicians, 22 family practice faculty, and 60 family practice residents in both rural and urban Nebraska concerning their perceptions of "core" procedures in family medicine and their perceived competency in performing them. Final response rate was 45%. There was general agreement concerning what constituted the core procedures in family medicine, although several newer procedures, such as flexible sigmoidoscopy, provoked more controversy.

Esophageal ulceration following doxycycline ingestion.

Esophageal ulceration occasionally occurs in patients taking doxycycline capsules or tablets. In the case described here, examination of biopsy specimens obtained at endoscopy showed polarizable matrix material in the ulcer bed, thus confirming the diagnosis.

A study of the superficial palmar arteries using the Doppler Ultrasonic Flowmeter.

The pattern of the superficial arteries of the hand has been studied utilising the Doppler Flowmeter technique. The superficial arteries of the hand formed several diversified patterns that permitted classification into well defined categories. The arcus palmaris superficialis was complete in 84% of the hands and incomplete in 16%.
