The clinical syndromes described with lesions of the hypothalamus are summarized in Table 9.5-9.7. The anterior hypothalamic syndrome consists of insomnia and loss of thirst regulatory mechanisms. In occasional larger lesions which interrupt the output from the supraoptic and paraventricular nuclei, diabetes insipidus has been noticed. In the tuberal region of the hypothalamus the most prominent findings are those that are caused by the disruption of the final common pathway to the pituitary. This results in endocrinopathy, most often the syndrome originally reported by Frohlich, with failure of sexual maturation and obesity. In the tuberal region, differences between lesions of the medial and lateral portions are quite marked. Medial lesions result in obesity while bilateral lesions result in anorexia and emaciation. The diencephalic syndrome of infancy with it's severe emaciation in young years and obesity in later years clearly indicates a different organizational pattern in the neonatal hypothalamus. Emotional disorders may be seen with lesions either in the medial or lateral hypothalamus at the tuberal level. Finally, in the posterior hypothalamic region, which includes the greatest effector apparatus, hypersomnia, apathy, and poikilothermia have been reported. Emotional disturbances and the Wernicke-Korsakoff syndrome also seemed to be associated with lesions in this area. The hypothalamus remains the single most important integrator of vegetative and endocrinologic regulation of the body. Cushing said of the hypothalamus, "here in this hidden spot, almost to be covered with a thumb nail, lies the very main spring of primitive existence: vegetative, emotional and reproductive".

We prospectively studied side effects about 54 patients with chronic hepatitis C treated with 3 to 10 MIU a day of interferon (IFN) alpha, which was administrated for 16 to 24 weeks. Every day, all of them wrote down every symptoms, by themselves, during its treatment. Any symptoms occurred in all patients and each incidence of symptoms such as fever, fatigue, headache, anorexia, arthalgia, myalgia, chill, itching, insomnia, nausea, numbness of hand and foot, irritability, diarrhea, eye ball pain, vomiting, were all higher than those which have been reported by some papers in Japan. So, it was considered that the symptom self-wrighting method by patient was useful to evaluate the entity of side effects. Furthermore, we studied 26 patients, who discontinued IFN treatment because of side effects and analyzed the background factors. Each incidence of symptoms of these patients were not always compatible to those incidences. But by observation of those symptoms, we could know severe side effects earlier.

A prospective study was carried out of 125 hospital inpatients with malignant disease, referred to the King's College Hospital advisory palliative care team. A palliative care assessment (PACA) tool was developed in order to assess the outcome of interventions made within two weeks of referral with regard to: symptom control, change in the patients' and their relatives' insight regarding diagnosis and prognosis, and facilitation of patient placement. Reliability was assessed by cross-observer analysis, and validity by comparison with data obtained using the McCorckle symptom distress scale in a separate group of hospice inpatients. At initial assessment, the commonest symptom was pain, as reported by 74% of patients. One-third of the patients were unsure of their diagnosis and placement had not been decided in 61%. In total, the team undertook 245 pharmacological interventions for symptom control, 165 interventions regarding insight and 114 interventions concerning placement. Analysis of the data showed statistically significant improvements in pain (p < 0.001), nausea (p < 0.009), insomnia (p < 0.004), anorexia (p < 0.001) and constipation (p < 0.02). Discussion regarding diagnosis significantly changed the insight of patients (p < 0.001) and relatives (p < 0.02). Appropriate placement was assisted by interventions undertaken by the team. This study shows that a hospital palliative care team is effective at improving symptom control, facilitates understanding of the diagnosis and prognosis, and contributes to the appropriate placement of patients.

Recently, it has been reported that major depression is accompanied by changes in plasma protein concentrations indicative of an acute-phase protein (APP) response. The purpose of the present study was to examine total serum protein (TSP) and the electrophoretically separated major fractions of serum proteins (SP), i.e., albumin (Alb), alpha 1, alpha 2, beta and gamma globulin, in depression. Highly significant differences were found in TSP and the separated SP fractions between major depressed patients and normal controls and between melancholic and minor depressed patients. Major depressed subjects showed significantly lower TSP and Alb concentrations and a higher percentage of the alpha 1 globulin fraction than normal controls and minor depressed subjects. Major depressed subjects had significantly higher and lower percentages, respectively, of alpha 2 and gamma globulin fractions than normal controls. In depressed subjects, there were significant negative correlations between TSP or Alb concentrations and severity of illness. Psychomotor retardation and anorexia were psychopathological correlates of lower TSP and Alb concentrations while middle insomnia and psychomotor retardation were related to changes in the alpha 2 globulin fractions. Basal plasma cortisol values were significantly and positively related to serum alpha 2 globulin. The results support the view that major depression is accompanied by an APP response.

Fluvoxamine belongs to the class of selective serotonin reuptake inhibitors (SSRIs) which have recently gained large popularity as antidepressant agents essentially because they lack the most troublesome adverse effects of older antidepressants (i.e. tricyclic antidepressants) such as anticholinergic effects and cardiotoxicity. Recent studies in the literature suggest that HIV-1 infected subjects are affected by depressive episodes with a relatively high frequency, often requiring an antidepressant treatment. Due to its favorable adverse effects profile, we used fluvoxamine as first line treatment for sixteen depressed HIV-1 infected subjects. They were administered the drug at a daily dosage of 100 mg in the evening. Fluvoxamine provided a good clinical efficacy for six of these patients, whereas the other ten had to discontinue the drug because of the presence of severe adverse effects such as acute total insomnia, gastro-intestinal disturbances together with anorexia, aggressive and impulsive behavior and excessive sedation. The observed fluvoxamine side-effects are not typical or specific for this particular patient group since they are also described in seronegative subjects taking fluvoxamine; however, our findings seem to indicate that they become more frequent and more severe when the drug is administered to HIV-1 infected patients.

The effect of previous physical conditioning on young well-conditioned mountaineers in relationship to acquiring acute mountain sickness is controversial. Data show both increased and decreased effects on the incidence of altitude illness. How general tourists at moderate altitudes are affected is unknown. To determine the influence of sea-level habitual physical activity on the incidence of mountain sickness, we surveyed 205 participants in a scientific conference at 3,000 m (9,840 ft). A 36-item questionnaire was distributed to the subjects 48 hours after arrival at altitude. Their sea-level physical activity (SLPA) was measured by a published and validated instrument that included questions about patterns of work, sporting, and leisure-time activities. Acute mountain sickness was defined as the presence of 3 or more of the following symptoms: headache, dyspnea, anorexia, fatigue, insomnia, dizziness, or vomiting. Most of the respondents were male (62%) from sea level (89%) with a mean age of 36 +/- 8.7 (standard deviation) years (range, 22 to 65). Nearly all (94%) were nonsmokers, and 28% had acute mountain sickness. The mean SLPA score was 8.0 +/- 1.3 (range, 5.1 to 12.0). No statistically significant difference in mean SLPA scores was found between those with and without acute mountain sickness (8.1 versus 7.8), nor in the individual indices (work, 2.5 versus 2.4; sport, 2.9 versus 2.7; leisure, 2.8 versus 2.7). We conclude that habitual physical activity performed at sea level does not play a role in the development of altitude illness at moderate altitude in a general tourist group.

Several pharmacologic agents provide antihistamine effects by acting at the H1 histamine receptor site. The classic agents are relatively nonselective, resulting in a wide range of effects, both therapeutic and undesirable. The newer agents preferentially block peripheral H1 receptor sites and, consequently, have fewer side effects, including sedation. Antihistamines are useful in the treatment of allergic conditions, Parkinson's disease, insomnia and some forms of nausea, and provide symptomatic relief of cough and other conditions associated with respiratory tract infections. Certain agents may play a role in the treatment of asthma and anorexia. Selection of a specific agent should be based on cost and the minimization of side effects. The classic antihistamines provide an inexpensive and highly effective means of treating histamine-mediated symptoms. The bothersome central nervous system side effects can be alleviated by taking the drugs at bedtime; their prolonged tissue half-life allows dosing once or twice a day for 24-hour clinical relief. The newer, more expensive nonsedating antihistamines are acceptable alternatives for patients who are incapable of tolerating the effects of classic agents.

In a prospective study of 167 patients with head and neck cancer, we assessed the causes and mechanisms of pain, as well as the efficacy and side effects of analgesic treatment, along World Health Organization (WHO) guidelines. The majority of patients had pain caused by cancer (83%) and/or treatment (28%), 4% had pain due to debility, and 7% had pain unrelated to cancer. Palliative antineoplastic treatment was performed in 32% of patients. Systemic analgesics were administered on 97% of a total of 8,106 treatment days, and coanalgesics or adjuvant drugs on 100%. The treatment proved to be very successful, as severe pain was experienced only during 5% of the observation period. In the absence of serious side effects, the most frequent symptoms observed were insomnia, dysphagia, anorexia, constipation, and nausea. The use of analgesic and adjuvant drugs along WHO guidelines to treat pain in head and neck cancer is highly effective and relatively safe.

Felbamate is currently being developed as an antiepileptic agent. Although its mechanism of action has yet to be fully elucidated, felbamate appears to inhibit both the spread of seizures and increase seizure threshold in animal models. Data available in the clinical setting provide evidence that, at doses of up to 3600 mg/day as an adjunct to existing antiepileptic therapy or as monotherapy following substitution for other medications, the drug reduces the frequency of partial onset seizures in adult patients refractory to conventional antiepileptic treatments. Felbamate is also effective in the treatment of Lennox-Gastaut syndrome in children, a severe epilepsy which is usually refractory to antiepileptic agents. The effect of felbamate in the treatment of generalised tonic-clonic seizures in adults with partial onset seizures which are secondarily generalised is promising but requires clarification in large-scale trials. The most common adverse effects occurring during administration of felbamate are mild to moderate gastrointestinal (nausea, vomiting and anorexia) and central nervous system (headache, somnolence, diplopia, dizziness and insomnia) disturbances. Drug interactions with other antiepileptic agents may prove problematic in terms of adverse effects. Thus, at this stage of its development, the antiepileptic efficacy of felbamate in treatment-refractory patients with partial onset seizures and Lennox-Gastaut syndrome has been proven but efficacy in generalised tonic-clonic seizures requires further substantiation in large well controlled and well designed clinical trials. In addition, a more comprehensive base of comparative clinical trials data is necessary to further clarify issues of relative efficacy and tolerability compared with other antiepileptic agents. The clinical implications of the drug interactions associated with felbamate also require more detailed investigation. These data will be awaited with interest and when available will help to place felbamate in perspective in the management of epilepsy.

The withdrawal of heterocyclic antidepressants and antipsychotic agents can produce nausea, emesis, anorexia, diarrhoea, rhinorrhoea, diaphoresis, myalgias, paraesthesias, anxiety, agitation, restlessness and insomnia. The withdrawal of monoamine oxidase (MAO) inhibitors may result in severe anxiety, agitation, pressured speech, sleeplessness or drowsiness, hallucinations, cognitive impairment, delirium, suicidality and delusions of persecution. The withdrawal of antipsychotic agents may give rise to symptoms preceding the onset of psychosis. These potential harbingers of relapse include anxiety, agitation, restlessness and insomnia. The withdrawal phenomena reviewed are usually prevented by gradually reducing the total daily dosage of the pertinent drug. Antimuscarinic agents often alleviate the distress produced by the withdrawal of tricyclic antidepressants and antipsychotic agents. MAO inhibitor withdrawal syndromes may constitute medical emergencies. The prevention of the evolution of a MAO inhibitor withdrawal-precipitated syndrome is a high priority.
