BACKGROUND AND PURPOSE Despite the frequent use of clinical rating scales in multicenter therapeutic stroke trials, no generally acceptable method exists to train and certify investigators to use the instrument consistently. We desired to train investigators to use the National Institutes of Health Stroke Scale in a study of acute stroke therapy so that all(More)
BACKGROUND This prospective multi-institutional study was designed to define the accuracy of ultrasonography, when performed in an orthopaedic surgeon's office, for the diagnosis of rotator cuff tears. METHODS An anatomic diagnosis and a treatment plan were made on the basis of office-based shoulder ultrasonography, physical examination, and radiographs(More)
OBJECTIVE To evaluate the risk factors, type, and frequency of complications during video-EEG monitoring with subdural grid electrodes. METHODS The authors retrospectively reviewed the records of all patients who underwent invasive monitoring with subdural grid electrodes (n = 198 monitoring sessions on 187 patients; median age: 24 years; range: 1 to 50(More)
PURPOSE The purpose of this study was to determine the safety and durability of traditional surgical treatment for asymptomatic infrarenal abdominal aortic aneurysms (AAAs) in a large series of patients who underwent open operations during the decade preceding the commercial availability of stent graft devices for endovascular AAA repair. METHODS From(More)
OBJECTIVE To determine the degree of concordance between clinical cause of death and autopsy diagnosis in a medical ICU (MICU) setting. DESIGN Retrospective medical chart and autopsy report review. SETTING MICU in a tertiary referral hospital. PATIENTS Consecutive admissions to an MICU over a 2-year period from January 1, 1994, to December 31, 1995.(More)
BACKGROUND Regional anesthesia is known to prevent or attenuate the surgical stress response; therefore, inhibiting surgical stress by paravertebral anesthesia might attenuate perioperative factors that enhance tumor growth and spread. The authors hypothesized that breast cancer patients undergoing surgery with paravertebral anesthesia and analgesia(More)
BACKGROUND Portable instruments that measure the prothrombin time and automatically calculate the international normalized ratio (INR) with the use of a drop of whole blood have simplified the treatment of patients who are receiving warfarin therapy. The accuracy of these portable monitors has never been determined by comparing INR results with a criterion(More)
OBJECTIVE We sought to reintroduce a historical procedure-intracapsular tonsillar reduction (partial tonsillectomy or tonsillotomy)-for tonsillar hypertrophy causing obstructive sleep disordered breathing (OSDB) in children, as well as to determine whether partial tonsillectomy, compared with conventional (total) tonsillectomy when performed by more than(More)
AIMS The purpose of this study was to adapt the IIQ-7 to suit the Egyptian culture and then to assess validity and reliability of the adapted and translated IIQ-7 and UDI-6. METHODS IIQ-7 was modified to suit Egyptian culture. Linguistic validation of the two questionnaires was done. Initial test-retest reliability and internal consistency of adapted(More)
OBJECTIVE To review our experience with intracapsular tonsillectomy using powered instrumentation in the management of tonsillar hypertrophy causing obstructive sleep-disordered breathing in children. STUDY DESIGN Retrospective case series. METHODS Intracapsular tonsillectomy, a form of partial tonsillectomy performed with an endoscopic microdebrider,(More)
