Abstract: Preoperative evaluation of parotid tumors still poses difficult problems for the head and neck surgeon. The complex anatomy of the parotid space leads to difficulty in localizing these tumors. In addition, physical examination will rarely determine whether a parotid lesion is benign or malignant. High resolution CT scanning with contrast and fine needle aspiration can provide enough preoperative information to enable the surgeon to counsel his patient concerning possible risks and the extent of surgery that may be indicated. We are able to determine tumor location, multiple or bilateral masses, associated adenopathy, and often specific tumor histology. Forty-two parotid aspirates and 26 CT scans were reviewed and correlated with their postoperative pathology specimen. Parotid aspiration cytology was found to be a highly accurate and safe procedure for preoperative determination of parotid pathology. However, the CT scan was specific only in defining the anatomic localization and extent of a parotid mass.

Abstract: To determine if constituents of cotton plants might play a role in byssinosis by injuring pulmonary epithelium, we added extracts of cotton dust, green bract, and field-dried bract to human A549 and rat type II pneumocytes. Injury was measured as pneumocyte lysis and detachment, and inhibition of protein synthesis. Extracts of cotton dust and field-dried bract produced significant dose- and time-dependent lysis and detachment of both target cells, while green bract extract was less damaging. Extracts treated with polyvinylpolypyrrolidone to remove tannins produced significantly less injury. In contrast, purified 5,7,3',4'-tetrahydroxy-flavan 3,4-diol (THF), a tannin in cotton dust and bract, caused substantial cell damage. Field-dried bract extract and THF also produced dose-dependent inhibition of pneumocyte protein synthesis. Endotoxin levels did not correlate with observed injury. THF added to rat tracheal explants caused epithelial disruption and desquamation, whereas endotoxin did not. Instillation of cotton dust and field-dried bract extract in rat lungs produced disruption of bronchial epithelium and smooth muscle constriction, while polyvinylpolypyrrolidone-treated cotton dust extract produced no injury. These findings suggest that extracts of cotton plants are toxic to alveolar, tracheal, and bronchial epithelium and that THF or other tannins may be the responsible agents.

Abstract: To increase the survival rate for out-of-hospital cardiac arrest, improvements in training must be made so that lay rescuers are motivated and have the ability to get involved. To overcome some of the fear and lack of involvement, better education strategies are needed. Adults learn didactic information through understanding and skills through repetition and reinforcement. Due to the fact that there is limited time that adults will commit to learning CPR, methods of simplification of the techniques need to be used so that there can be sufficient repetition and reinforcement. Teaching two-rescuer CPR to lay rescuers should not routinely be done. Most adults, particularly those around high-risk individuals, should learn one-rescuer CPR. Infant resuscitation should be taught predominantly to those around small children. Methods of reinforcement through the mass media should be attempted on a routine basis. Whenever possible the courses should be spread over a period of time to allow for repetition and reinforcement, thereby maximizing learning. Advanced cardiac life support (ACLS) should be widely taught to health professionals. ACLS instruction needs to be spread over time, whenever logistically possible, to enhance learning and retention. Good, validated examinations are needed and should be routinely rotated. Better methods of evaluation are needed to look at the benefit of these types of programs and to improve the cost-benefit ratio.
