OBJECTIVE The introduction of high-resolution ultrasonography combined with color-coded Doppler imaging offered a breakthrough in the evaluation of the human fetal venous system, considerably enhancing our understanding of fetal venous circulation in normal physiologic conditions, as well as providing us the ability to study circulatory changes in abnormal circumstances. The purpose of this stu...

PURPOSE To determine whether there is a physiologic explanation for the predisposition of patients with certain angiographic characteristics to symptoms of hemorrhage and steal. METHODS Superselective transcatheter feeding arterial pressure and mean arterial pressure measurements were obtained before embolotherapy in 32 patients with cerebral arteriovenous malformations. Pressures were correl...

Transmission of pathogenic Leptospira between mammalian hosts usually involves dissemination via soil or water contaminated by the urine of carrier animals. The ability of Leptospira to adapt to the diverse conditions found inside and outside the host is reflected in its relatively large genome size and high percentage of signal transduction genes. An exception is Leptospira borgpetersenii sero...

The perceptual method of classifying dysarthria is considered the “gold standard” for clinically differentiating the types of dysarthria. Darley et al., 1 pioneered the use of perceptual classification system to identify clusters of salient perceptual characteristics in speech that are associated with lesions in the central and peripheral nervous system. This system is also popularly referred t...

Vulvar skin disease is a common reason for consultation. The vulva, like the rest of the skin, can be affected by numerous diseases of various etiologies, but its particular anatomic and physiologic characteristics create additional diagnostic and therapeutic difficulties. The study of vulvar disease is emerging as a new branch of dermatology. In this article, we examine the characteristics of ...

Airway management in critically ill patients involves the identification and management of the potentially difficult airway in order to avoid untoward complications. This focus on difficult airway management has traditionally referred to identifying anatomic characteristics of the patient that make either visualizing the glottic opening or placement of the tracheal tube through the vocal cords ...

Over the past several decades, advances in prenatal evaluation, neonatal care, diagnostic techniques, anesthesia, and clinical management have enhanced care of pediatric surgical patients. Neonates have their own physiologic characteristics that must govern their care. The most distinctive and rapidly changing functions occur during the neonatal period. This is due to the newborn infant’s adapt...
