Abstract: A variety of effective drugs are available for the treatment of schizophrenia. Knowledge of the side-effect spectrum of the various classes of antipsychotic drugs is necessary for the clinician to arrive at a rational choice of medication. In general, the preferred drug will be a high-potency neuroleptic. The following basic principles of clinical psychopharmacology should be followed: Consider risk and benefits; clinical experience is prerequisite; establish the diagnosis; select the appropriate class of psychotropic drug for the primary diagnosis; within drug class, the drugs are usually equally effective for patients with the diagnosis; give a dose that is high enough to be effective; choose target symptoms that can be monitored to indicate when to stop or increase the drug; avoid use of multiple drugs when possible; drugs are only one element in a comprehensive treatment strategy. Other modalities need equally careful consideration, e.g., psychotherapy, group therapy, family treatment, and vocational rehabilitation; and consultation with other subspecialists should be sought readily when indicated.

Abstract: A carotid-cavernous fistula recurred 16 years after a Hamby procedure. The recurrence was manifested by subarachnoid hemorrhage originating from dilated draining pial veins. The fistula was closed with a balloon catheter introduced through a patent remnant of the cervical carotid artery. Patients who have previously undergone Hamby trapping and embolization should be reassessed for an occult fistula that could predispose them to intracranial bleeding.

Abstract: We assessed in ponies the adequacy of using rectal (Tre) rather than arterial temperature (Tar) under conditions common to ventilatory control experiments, i.e., CO2 breathing, thermal stress, and particularly exercise. We were interested in whether, and to what extent, Tar-Tre differences could lead to errors in arterial blood gas corrections. At control environmental temperatures (Ta) of 5 degrees C in the winter and 21 degrees C in the summer, Tar and Tre (37.1 degrees C) did not differ (P greater than 0.05). Elevating winter or summer Ta by 10-18 degrees C for 2-days or lowering summer Ta by 9 degrees C (2-days) did not change Tar or Tre (P greater than 0.05). Furthermore, elevating inspired PCO2 to 42 Torr for 15 min did not alter Tar or Tre from control (P greater than 0.05). During treadmill exercise, at 1.8 mph 5% grade, Tar and Tre did not change significantly (P greater than 0.05) from rest by 11 min of work. At 3 mph 5% grade, Tar increased progressively by 0.3 degrees C (P less than 0.05) while Tre tended to increase 0.1 degree C by 11 min. During moderate exercise at 6 mph 5% grade, Tar increased 0.9 degree C (P less than 0.05) while Tre increased 0.25 degree C (P less than 0.05). Finally, by 6 min of heavy exercise at 8 mph 20% grade, Tar increased 2 degrees C (P less than 0.05) while Tre increased 0.5 degree C (P less than 0.05). The Tar-Tre differences during the latter three work loads were statistically significant (P less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
