Psychiatric aspects of head and neck surgery. Part I: New surgical techniques and psychiatric consequences.

Individuals who undergo head and neck surgery experience extreme stressors that go beyond those which occur with the usual surgical patient. This paper will review the literature and discuss the psychiatric consequences of otolaryngeal surgery. In addition, new head and neck surgical techniques, which offer special challenges to the patient as well as to the psychiatric consultant, will be examined. Tracheostomy, which occurs as a result of head and neck surgery, is of particular importance with regard to postoperative adaptation and is a significant complication that must be reckoned with.     

Partial reversal of the hypogonadotropic hypogonadism of obese men by administration of corticosuppressive doses of dexamethasone

Obese men have hyperestrogenemia-induced hypogonadotropic hypogonadism (HHG), due, we believe, to increased rarmatization of adrenal androgens by the increased bulk of aromatase-containing adipose tissue. We studied the effects of corticosuppressive doses of dexamethasone (D) on 24-h mean plasma total and free estradiol (E2), estrone (E1), LH, FSH, total and free testosterone, delta 4-androstenedione (delta 4), and sex-hormone-binding globulin (SHBG) in nine obese men and five normal-weight controls. In the obese men, the following hormones fell: E2 [59 +/- 19 to 39 +/- 11 pg/ml (P less than 0.01)], E1 [93 +/- 41 to 50 +/- 25 pg/ml; (P less than 0.01)], delta 4-androstenedione [120 +/- 80 to 55 +/- 27 ng/dl; (P less than 0.02)]; free E2 [1.6 +/- 0.4 to 1.1 +/- 0.2 pg/ml; (P less than 0.01)], SHBG [12.8 +/- 5.3 to 8.2 +/- 3 nM/l; (P less than 0.04)]. FSH rose from 4.8 +/- 3.2 to 7.6 +/- 4.2 miu/ml (P less than 0.01). LH, total and free testosterone showed no significant change. In the nonobese men, there were decreases in total E2 [(34 +/- 6.8 to 25 +/- 10 pg/ml; P less than 0.04)], SHBG [16.8 +/- 7.5 to 10.4 +/- 2.0 nM/l: P less than .05.], free E2 [0.9 +/- 0.2 to 0.7 +/- 0.3 pg/ml: P less than 0.05], delta 4 [91.4 +/- 3.6 to 33.4 +/- 16.7 ng/dl; P less than .01] and total T [492 +/- 44 to 393 +/- 121 ng/dl; P less than 0.04]. There was no significant change in E1, FSH, LH or free T.(ABSTRACT TRUNCATED AT 250 WORDS)     

Effects of cocaine alone and in combination with bromocriptine in human cocaine abusers.

This study was conducted to determine whether the acute administration of bromocriptine, a dopamine agonist, modulates the acute pharmacologic effects of i.v. cocaine in humans. Eight current users of i.v. cocaine who were not seeking treatment for their cocaine abuse completed the study while they were inpatients on a research unit. Twelve drug conditions were tested in all subjects in randomized order under double-blind, double-dummy conditions and included cocaine (0, 12.5, 25 and 50 mg, i.v.) in combination with bromocriptine (0, 1.2 and 2.5 mg given orally 2 hr before the cocaine injection). Physiologic and subject- and observer-rated responses were measured. Cocaine alone significantly increased pupil diameter, heart rate and blood pressure, and ratings of drug effect, good effects, liking and rush. Bromocriptine alone significantly increased pupil diameter and heart rate, decreased blood pressure and had only minor effects on subjective measures. There were significant cocaine/bromocriptine interactions on diastolic and mean arterial blood pressure, with combinations producing significantly smaller increases compared to cocaine alone, and on heart rate, with combinations producing significantly larger increases compared to cocaine alone. The physiologic and subjective effects of cocaine were not modified by pretreatment with bromocriptine in any other way that might indicate either a therapeutic benefit or a safety concern. However, bromocriptine alone produced undesirable effects (fainting) that should be considered before administration to outpatient cocaine abusers. Any possible therapeutic benefits of acute administration of bromocriptine in cocaine abuse are not likely to be due directly to modulation of the acute effects of cocaine.     

Enhancement of cocaine's abuse liability in methadone maintenance patients

The present study was conducted to determine whether methadone maintenance alters the pharmacodynamic effects of single doses of cocaine. Twenty-two current users of IV cocaine who were not seeking treatment for their illicit cocaine use participated while living on a research unit. Eleven were maintained on methadone 50 mg PO daily as treatment for their opioid abuse; 11 were opioid abusers who were not physically dependent on opioids and who provided opioid-free urines throughout the study. Each subject received acute cocaine challenge doses of 0, 12.5, 25, and 50 mg intravenously in random order under double-blind conditions in separate test sessions. Physiologic and subject-rated responses were measured before injection and for 2 h after. In the methadone maintenance group, cocaine challenge sessions occurred 15.5 h after the daily methadone dose. There were significant differences between the methadone-dependent and nondependent groups: 1) baseline differences related to chronic methadone administration and not associated with cocaine administration (lower respiration rates and pupil diameter; higher skin temperature) and 2) differences in response to cocaine administration; cocaine-induced increases in subject ratings of Drug Effect, Rush, Good Effects, Liking, and Desire for Cocaine and in heart rate were greater in the methadone maintenance patients compared to the non-dependent group. These results indicate that the positive subjective effects and some physiological effects of cocaine are enhanced in methadone-maintained individuals, suggesting a pharmacological basis for the high rates of cocaine abuse among methadone maintenance patients.Some of these data were presented at the annual meeting of the Committee on Problems of drug Dependence, Keystone, Colorado, June 1992     

全国哨点监测性病流行情况初步分析(1993-1996)

Psychiatric aspects of head and neck surgery. Part II: Body image and psychiatric intervention

Surgery of the head and neck leads to profound changes of body image, including disfigurement and difficulties with verbalization. The psychologic importance of alterations in these areas will be discussed as well as their effect on the conduct of psychiatric treatment. Psychiatric intervention in this population demands an active approach and special preparation for the therapeutic encounter is necessary.     

A new tool for consultation-liaison funding: modified DRGs to reflect psychiatric comorbidity.

Funding for consultation-liaison (C-L) psychiatry remains an overriding obstacle to its implementation and practice. Several methods have been described to access funds for this subspecialty of psychiatry, but none has been enacted as a policy by third party payers to reimburse adequately for the service. In addition, although the consultation portion of the effort can be reimbursed in part in some cases through fee for services, the liaison portion is dependent on the donation of psychiatry time or the largesse of the host department. The efforts at Stanford to capitalize on the findings that psychiatric and medical comorbidity results in prolonged length of hospital stay and increased health resource utilization suggest that specific DRGs would be important patient groups to screen and charge for psychiatric services. Furthermore, DRGs that are accompanied by a high frequency of psychiatric comorbidity are a "target" for an additional funding aliquot to assess and manage the patient's psychiatric status.
