Cocaine use and abuse continue to overwhelm urban economic, social, and health care systems. Patients frequently present to the emergency department with life-threatening manifestations of cocaine use, including trauma, acquired immune deficiency syndrome, psychomotor agitation, and cardiovascular collapse. Adequate treatment of the cocaine-intoxicated patient requires a critical understanding of the risk-to-benefit ratios for pharmacologic, toxicologic, and surgical or obstetric interventions. The pharmacologic and physiologic bases for the vascular manifestations of cocaine toxicity and experimental evidence for treatment strategies are reviewed.

Mental symptoms are common in patients with AIDS. Optimal management involves the identification and treatment of underlying mental disorders rather than symptomatic treatment alone. Organic mental disorders are very frequent in AIDS, particularly with seriously ill patients who are medical inpatients. There is a high priori probability that such common symptoms as agitation, irritability, and insomnia will be caused by an organic mental disorder. Psychopharmacology in the patient with AIDS requires considerable caution. Lower doses and careful surveillance for subtle neuropsychiatric side effects are necessary. Routine medical contact with a compassionate physician may be of inestimable value to the patient in coping with the fear and dread that surround the illness.

An occupational therapist presented her 45-minute program called AIDS Education and Safe Sex 5 times to female mental patients in the locked ward of Cedarcrest Regional Hospital in Newington, Connecticut, to inform them about safe-sex practices and AIDS. She first administered a pretest then spoke briefly about AIDS and safe-sex practices. The lecture emphasized various important points such as no cure for AIDS exist, casual contact (e.g., kiss on the cheek, handshake) cannot transmit HIV, and effectiveness of using latex condoms. The occupational therapist spent much of her time addressing myths about AIDS and what safe-sex practices are. The patients discussed sexual abuse and dishonest partners. She administered a posttest which was the same as the pretest. Some sessions attracted more people than did other sessions. Test scores increased for every patient and for every session. They ranged from a 5% (68-73%) increase for the 3rd session to a 24% (67-91%) increase for the last session. She was not able to determine, however, whether the increased knowledge would translate into positive behavioral changes. Patients' psychiatric symptoms may have interfered with learning resulting in less than ideal improvements in knowledge. These symptoms were hypomanic behavior, restlessness, and distractibility. Perhaps other sessions with experiential techniques (e.g., putting condoms on dummies) would increase their understanding. This program helps fill the information gap not provided by the mass media which avoid mentioning safe-sex practices.

A case of cryptococcal meningitis in a patient with the acquired immunodeficiency syndrome (AIDS) is described, as well as the epidemiology, pathogenesis, clinical manifestations, diagnosis, and therapeutic management of the disease. In July 1987 a 38-year-old white man was admitted to the hospital because of confusion, disorientation, and headache. His medical history was notable for a positive human immunodeficiency virus test. Culture of the cerebrospinal fluid was positive for Cryptococcus neoformans. The patient was started on amphotericin B 16 mg/day (0.3 mg/kg/day) intravenously and flucytosine 2 g every six hours (150 mg/kg/day) orally. Despite premedication with diphenhydramine and acetaminophen, he experienced rigors that were treated with hydrocortisone and meperidine. Three weeks later he was discharged on flucytosine 2 g orally every six hours and amphotericin B 50 mg intravenously every other day. One week later the patient developed fever and chills; blood cultures were positive for methicillin-sensitive Staphylococcus aureus, and his peripheral leucocyte count was 1.8 X 10(3)/cu mm. Flucytosine was discontinued, and he was treated with intravenous nafcillin while remaining on amphotericin B. In October the patient complained of nausea, vomiting, weakness, and agitation. A CSF latex agglutination titer for cryptococcal antigen was 1:32. He was treated with amphotericin B 50 mg daily until symptoms resolved and then continued on amphotericin B 50 mg twice weekly. Cryptococcosis is the most common life-threatening fungal infection among AIDS patients. In contrast to immunocompetent hosts, this population invariably develops disseminated disease, with 85% having meningeal involvement. The most effective therapy for cryptococcal meningitis in patients with AIDS has not been established.(ABSTRACT TRUNCATED AT 250 WORDS)

Neuroleptic malignant syndrome (NMS) has been recently described following therapy with non strictly neuroleptic drugs that alter dopaminergic function, such as sulpiride and metoclopramide, and might occur more easily in patients with functional or organic brain disorders. We observed an AIDS patient who suffered from NMS following treatment with clotiapine for insomnia and agitation. Two months later, he presented with a similar syndrome following antiemetic treatment with alizapride. On both occasions, the symptoms completely regressed after the administration of dopaminergic and muscle relaxant drugs. The patient died of pneumonia one month after the last episode. The present paper describes the clinical and pathological findings.

Clinical electroencephalography is a relatively simple and inexpensive diagnostic tool with a high sensitivity for diffuse organic encephalopathy of various aetiologies but with a rather low specificity for the type of diagnosis. The highest sensitivity is shown in DAT and Parkinson dementia, and in these conditions the degree of EEG abnormality is correlated with the disease severity. Quantification of EEG makes these correlations more reliable and provides a method for monitoring therapeutic effects. Dementias with predominantly frontal pathology show much less EEG abnormality, and in these conditions the EEG is often normal despite obvious clinical dementia. Also, alcohol dementias often show normal EEG patterns. At an early stage of clinical evaluation, EEG may be useful in the discrimination of organic dementia from pseudodementia, because EEG is usually normal in depression, confusion, agitation and other psychiatric conditions. In pseudodementia due to intoxication with sedatives the EEG is usually dominated by diffuse beta activity. At the stage of differential diagnosis of an organic brain disorder, EEG cannot reliably discriminate between encephalopathies secondary to hydrocephalus, AIDS, cerebrovascular disease, B12 deficiency and primary degenerative diseases such as DAT. More specific EEG patterns are seen in acute cerebrovascular lesions, metabolic encephalopathies, i.e. of hepatic origin, Creutzfeldt-Jakob disease, herpes encephalitis, and nonconvulsive status epilepticus as possible causes of a rapidly deteriorating mental and neurological condition. Repeated EEG recordings over time would add significantly to the diagnostic information. New techniques such as topographical brain mapping, analysis of the EEG during REM sleep, coherence analysis of the EEG activity, and the combination of quantified EEG techniques with evoked potentials and event-related potentials will presumably add to the sensitivity as well as the specificity of the electrophysiological methods in the diagnosis of dementia.

Somatic symptoms often complicate the diagnosis and psychopharmacological treatment of depression in HIV illness. We treated 33 depressed HIV-positive men and women with medically symptomatic HIV or AIDS (CDC stages 2B, 2C, 3B, or 3C) in a 6 week open-label trial with sertraline, paroxetine, or fluoxetine, to assess their effectiveness and tolerability. We further assessed whether treatment of depression resulted in a reduction in both affective and somatic symptoms in this medically ill population. Twenty-four subjects (73%) completed the trial (7 on sertraline, 7 on paroxetine, 10 on fluoxetine), 20 (83%) of whom were clinical responders. Nine dropped out within 1-3 weeks of treatment because of adverse effects, mostly agitation, anxiety, and insomnia. Subjects who completed 6 weeks of SSRI treatment experienced significant reductions in both affective and somatic symptoms, many of the latter having been attributed to HIV rather than depression. These results suggest that, even in later stages of HIV illness, the contribution of depression to perceived somatic symptoms may be significant, and that these symptoms may improve with antidepressant treatment.

Astrocytes and microglia in the spinal cord have recently been reported to contribute to the development of peripheral inflammation-induced exaggerated pain states. Both lowering of thermal pain threshold (thermal hyperalgesia) and lowering of response threshold to light tactile stimuli (mechanical allodynia) have been reported. The notion that spinal cord glia are potential mediators of such effects is based on the disruption of these exaggerated pain states by drugs thought to preferentially affect glial function. Activation of astrocytes and microglia can release many of the same substances that are known to mediate thermal hyperalgesia and mechanical allodynia. The aim of the present series of studies was to determine whether exaggerated pain states could also be created in rats by direct, intraspinal immune activation of astrocytes and microglia. The immune stimulus used was peri-spinal (intrathecal, i.t.) application of the Human Immunodeficiency Virus type 1 (HIV-1) envelope glycoprotein, gp120. This portion of HIV-1 is known to bind to and activate microglia and astrocytes. Robust thermal hyperalgesia (tail-flick, TF, and Hargreaves tests) and mechanical allodynia (von Frey and touch-evoked agitation tests) were observed in response to i.t. gp120. Heat denaturing of the complex protein structure of gp120 blocked gp120-induced thermal hyperalgesia. Lastly, both thermal hyperalgesia and mechanical allodynia to i.t. gp120 were blocked by spinal pretreatment with drugs (fluorocitrate and CNI-1493) thought to preferentially disrupt glial function.

The purposes of this study were to describe the quality of life (QOL) of terminally ill patients in a home-based hospice program and to examine the relationship between QOL data and patients' symptom distress, ability to function, interpersonal communication (support from family and friends), well-being (their affairs in order), and transcendence (religious comfort/support) as recorded in their charts. QOL was measured by the Missoula-Vitas Quality of Life Index (MVQOLI), an instrument designed specifically for use with terminally ill patients. The study was conducted over a three-year period with 129 terminally ill patients enrolled in a home-based hospice program of care. The MVQOLI was administered to patients within 20 days of their admission to hospice. A retrospective chart review was conducted to determine patients' levels of symptom distress, ability to function, social support, whether or not their affairs were in order, and religious comfort/support. The mean age of participants in this study was 67, with 54.3 percent male and 45.7 percent female. Cancer was the primary diagnosis for 92.2 percent of the sample, and 35 percent of these patients had a diagnosis of lung cancer. Of the 7.8 percent non-cancer diagnoses, five were diagnosed with AIDS, four with chronic obstructive pulmonary disease, and one with chronic heart failure. The results of this study revealed positive scores on the five dimensions of the MVQOLI QOL scale, indicating that within 20 days of admission to hospice, patients rated their QOL as good to very good. Data obtained from the chart review also indicated that patients did not experience a great deal of symptom distress (e.g., pain, nausea, shortness of breath, and restlessness). A significant correlation existed between age and QOL; number of interventions and pain levels; and marital status, well-being, interpersonal relationships, and transcendence. Shortness of breath and well-being were significantly correlated with QOL. There was no significant correlation between gender, race, or closeness to death and the five dimensions of the MVQOLI and chart review assessments.

A hospice/palliative medicine consultation team was formed in July 1993 in a U.S. teaching hospital to provide patient care and education. The team consists of an attending physician, nurse, fellow, and any residents or medical students rotating on the service. More than 500 consultations are received each year. Beginning in January 1995,108 consecutive referrals to the service were assessed using a standard form completed by the nurse. The average age was 62 years. The gender of patients was 58% male and 42% female. At the time of consultation 87% were hospitalized on general medical services (including hematology/oncology), 4% were on surgical services, 3% on the neurology service, and 6% were in an intensive care unit. Cancer was the primary diagnosis in 52%, AIDS in 24%, with the rest being distributed among cardiac, renal, pulmonary, neurologic, and other diseases. The most prominent physical symptoms were 48% weakness/malaise, 44% pain, 28% dyspnea, and 23% agitation/confusion. The average length of time patients were followed was 2 days (range 1-10). We conclude that a hospice/palliative medicine consultation service sees a broad range of patients and problems and is a rich resource for teaching hospice and palliative medicine.
