We evaluated the efficacy and safety of a single injection technique with a small volume of anesthetic for ocular peribulbar anesthesia. We included 857 patients undergoing various ophthalmic procedures. Anesthesia consisted of a medial percutaneous injection of 5-6.5 mL of 2% lidocaine. At 2 min 85.6% of the patients had a motor block of at least 50% and(More)
The Circle of Willis was studied by Magnetic Resonance Angiography in 100 healthy subjects. In 41% of these cases, the arteries were arranged in the classically described way. In 21%, hypoplasia of the posterior communicating as. was noted, while in 13% the posterior cerebral as were found to originate from the internal carotid a.. In 9% of these cases,(More)
OBJECTIVE To determine the expression of VEGF in the placental tissue from pregnancies complicated by hypertension disorders of different clinical severity. DESIGN Prospective cohort study. SETTING Polyclinic of Careggi, University of Florence, Italy. SAMPLE Placentas from women with gestational hypertension (n= 20), pre-eclampsia (n= 20) and(More)
Morphologic and morpho-functional heart differences between healthy young athletes and healthy young subjects who do not practice agonistic sport have been studied using Color Doppler Echography (CDE). Overall, 68 subjects were enrolled in the study (age range: 19-26 yrs). Of them, 34 subjects (17 men and 17 women) were practicing sport agonistically; the(More)
A workshop in the clinical anatomy of the female pelvic viscera has been part of the training program for the first year residents in Gynecology and Obstetrics at the University of Padova since the 1999-2000 academic year. The purpose of the workshop is to offer a direct experience of practical anatomy despite a shortage of cadavers. It is designed for six(More)
One hundred healthy subjects (50 men, 50 women; age range: 18 to 90 years) with no history of occlusive arterial disease of the lower extremities were examined. In each, the principal arteries of the lower extremities were measured by Doppler ultrasound. The difference between the dimensions of the arteries of the right with those of the left was generally(More)
We measured by ultrasound the spleen, the kidneys, the pancreas in 323 children (age 0-12), the thyroid in 60 children of same age range, and all these organs in 180 adults (in adults we measured additionally the testis, the gallbladder and the choledochus). Children and adults were all healthy, without evidence of pathologies potentially involving these(More)
In 50 healthy subjects the internal diameter of the intracranial vertebral artery were measured by echocolor doppler method. The diameter of left vertebral a. was greater than that of the right in most subjects (58%); the mean left/right difference was statistically significant (p < 0.05). Analyzing men and women separately, the difference remained(More)
Ninety subjects with emodynamically significant atherosclerotic disease of the lower limbs were examined. They had no history of diabetes mellitus or hypertension. Each subject underwent a color Doppler ultrasonographic study of the common iliac, superficial femoral, and popliteal arteries. In each arterial segment, diameter and blood flow velocity were(More)
