ABSTRACT: Increasing the pH of epidurally administered local anesthetics hastens their onset of action and improves the quality of neural blockade. The effect of body position on the epidural spread of alkalinized 2% chloroprocaine HCl for the second stage of labor has not been reported. We studied the epidural cephalad…
ABSTRACT: Many health care providers practicing near the border between the United States and Mexico have serious concerns about their patients' using medications obtained in Mexico. Despite these concerns, the extent of this problem is not known. A survey administered in a publicly funded rural clinic and an urban private…
ABSTRACT: Previous studies have suggested that the hypoxia and/or hypercapnia associated with chronic lung diseases may lead to pituitary and gonadal dysfunction, with destruction of the sella turcica. It is unclear, however, whether these abnormalities were due to lung disease or to confounding factors. We studied the relationships between hormonal…
ABSTRACT: Spontaneous (nontraumatic) midbrain hemorrhage (SMH) is an uncommon condition whose diagnosis is greatly assisted by the use of cranial computerized tomography. Of 18 cases described in the English language literature, only two were diagnosed without the aid of CT. We report five cases of SMH in five normotensive patients….

A body of laws exists to address these conflicting rights. These laws, however, must evolve so as to strike…
ABSTRACT: The purpose of this present study was to determine whether intraoperative antibiotic uterine irrigation was effective in reducing febrile morbidity (Part 1), and to determine whether ticarcillin disodium (Ticar) or cefoxitin sodium (Mefoxin) was the more effective solution (Part 2). The indications for cesarean section had an effect on…
ABSTRACT: This report examines the role of fine needle aspiration (FNA) and frozen section (FS) examination in the management of salivary gland lesions, and is based on a review of 58 cases. FNA specimens were first classified as nonneoplastic, or as benign or malignant neoplasms. Identification of specific morphologic type…
ABSTRACT: We identified cysts in five kidneys of four patients who had lithotripsy. Three of these kidneys were evaluated with CT scans the day before and the day after lithotripsy and showed no change. The other two kidneys were studied by CT only after extracorporeal shock wave lithotripsy; hemorrhage was…
ABSTRACT: We reviewed the laboratory parameters, clinical information including presence or absence of stool pigmentation, and ultrasonographic findings in 67 patients with neonatal conjugated hyperbilirubinemia and liver biopsies. Hepatobiliary nuclear scintigraphy was done in 14 of the patients. Final diagnoses included extrahepatic biliary atresia, neonatal hepatitis, cystic fibrosis, metabolic liver…
