Since malignant melanoma is a rare malignancy in Japan, little is known about the cytogenetic abnormalities in Japanese patients. We report a case of malignant melanoma showing complex chromosomal abnormalities. A 70-year-old woman was admitted to our hospital because of anorexia, delirium, and right hemiplegia. Cranial CT disclosed several metastatic brain tumors. Multiple subcutaneous and intra-abdominal metastases were also found. A diagnosis of metastatic malignant melanoma was made by biopsy of a subcutaneous tumor. Chromosomal analysis of the tumor cells disclosed complex karyotypic abnormalities including novel unbalanced whole arm translocations der (8; 14) (q10; q10) and der (11; 15) (q10; q10).

Recovery and outcome parameters of children undergoing surgery as outpatient are reported. There are minor differences between different drugs in terms of outcome, speed of recovery and recovery adverse events. There is a trend in increasing adverse events (most of all emergence delirium) during recovery from sevoflurane and nitrous oxide. Most complications (pain, nausea, vomiting, croup) are transient and managed before discharge. The most frequent complications at home are undertreated pain, loss of appetite, and behavioral changes.

The management of dementia patients encompasses pharmacologic, behavioral, and psychosocial intervention strategies. Before pharmacologic intervention is instituted, it is important that sources of excess disability and comorbidity be eliminated or reduced. Identification of comorbid medical and psychiatric conditions, such as depression and delirium, should be identified and appropriately treated. Providing caregivers with education, support, and practical advice is a critical component of the management of the demented patient. The current standard of care for pharmacologic management of the cognitive and functional disabilities of AD consists of the combination of a cholinesterase inhibitor and high-dose vitamin E. This standard is based on the results of large-scale, double-blind, placebo-controlled trials. Cholinesterase inhibitors are the only FDA-approved pharmacologic treatments for AD. Cholinesterase inhibitors have been shown to be effective in the treatment of the cognitive, behavioral, and functional deficits of AD. Large-scale placebo-controlled trials of tacrine, donepezil, rivastigmine, and galantamine have demonstrated moderate benefits in patients with mild to moderate AD. Donepezil, rivastigmine, and galantamine are the first-line choices in the treatment of AD because of their lack of hepatotoxicity, ease of administration, few significant drug-drug interactions, and mild to moderate side effects. There are few contraindications to the use of cholinesterase inhibitors. Known hypersensitivity to a specific drug or its derivatives is the only true contraindication. Cautious administration of cholinesterase inhibitors is advised in patients who have a previous history of allergy or adverse reactions to prior cholinesterase inhibitors, severe liver disease, preexisting bradycardia, peptic ulcer disease, current alcoholism, asthma, or chronic obstructive pulmonary disease. Nausea, vomiting, diarrhea, and anorexia are the most common side effects of cholinesterase inhibitors. These gastrointestinal side effects can be minimized by gradual dose increases, administration with food, adequate hydration, and judicious use of an antiemetic. Vitamin E has been demonstrated to slow the progression of AD in several small and one large placebo-controlled trials. Because of its low cost and safety, it is recommended in addition to a cholinesterase inhibitor for the treatment of AD. There are no FDA-approved treatments for DLB and VaD. One small placebo-controlled trial demonstrated that rivastigmine may be effective in the treatment of DLB. More large-scale placebo-controlled trials are needed to confirm the results of this study. Treatment of VaD focuses on the control, identification, and management of cerebrovascular disease and vascular risk factors. Although there are no peer-reviewed reports on the efficacy of cholinesterase inhibitors for VaD or mixed AD/VaD, early reports suggest that these agents may also be effective for mixed AD/VaD. The indications for the use of cholinesterase inhibitor drugs are eventually likely to broaden to include DLB, mixed AD/VaD, and AD in its more advanced stages.

A 30-year-old white man with schizophrenia developed anorexia and nausea, and was admitted to hospital for confusion and delirium. He was on olanzapine, 10 days prior to admission. On admission, typical neuroleptic malignant syndrome (NMS) developed with elevated body temperature (39.7 degrees C), obtundation, tremor, rigidity, diaphoresis, fluctuating pupillary diameter, tachycardia, labile hypertension, elevated serum creatine kinase and severe hypernatremia (190 meq/l). Olanzepine was stopped few days after admission to the hospital and the NMS manifestations resolved by hospital day 12. The patient had all of the major manifestations of NMS. There was no other likely explanation for his illness. This is the first case reported in which NMS was associated with olanzapine and extremely elevated levels of serum sodium.

In the article, the author develops an analysis of external and intrapsychic factors related to adults' insomnia. First she undertakes a literature review to describe semiological, evolutive and etiological levels of insomnia. From a semiological point of view, it is usual to differenciate initial insomnia (associated to the first phase of sleeping), intermittent insomnia (related to frequent awakenings) and final insomnia (related to early morning awakenings). From an evolutive point of view, we can identify transitory insomnia (characterized by frequent awakenings) and chronic insomnia. On the other hand, we are allowed to distinguish organic insomnia (disorder where an organic cerebral injury is demonstrated or suspected) from insomnias related to psychiatric or somatic disease or idiopathic one. Then, the author makes a literary review to identify various insomnia causes and points out. Social factors: insomnia rates are higher by divorced, separated or widowed people. Percentages are higher when scholastic level is weak, domestic income is less then 915 O a month, or by unemployed people. Besides, sleep quality is deteriorated by ageing. Sleeping and waking rhythm is able to loose its synchronization. Complaints about insomnia occur far frequently from women than men. Environmental factors: working constraints increase sleep disorders. It is possible to make the same conclusion when we have to face overcharge of external events, deep intrapsychic conflicts (related to grief, unemployment, damage or hospitalization) or interpersonal conflicts' situations where we are confronted to stress related to socio-affective environment, lack of social support or conjugal difficulties. Medical and physiologic causes: legs impatience syndrome, recurrent limbs shakings syndrome, breathe stop during sleep, narcolepsy, excessive medicine or hypnotic drugs use, some central nervous system injuries, every nocturnal awakening (related to aches.), surgical operation. Chronobiological factors: night working or day-night shift produce insomnia by desynchronization. It is the same for time lag related to jet-lag flights. Significant gaps between the internal biological clock and environmental synchronizators, such as phase delay sleep, phase advance sleep, sleep-waking cycle longer than 24 (25) hours, or variations in sleep-awakening cycle, are of less importance. Toxic factors are numerous: amphetamines, antidepressors, medication against anorexia and tubercular disease, caffeine and alcohol excessive use, chronic alcoholism. Behavioral factors: enduring insomnias are related to poor nightroutines (to go to sleep too early, to read or to look at T.V. when going to bed). The same effect is produced by regular intellectual activities close to bedtime or by a late meal in the evening, by an noisy or unhealthy environment, by physical hyperactivity or sleeping after each lunch. Psychiatric factors: insomnia often appears with psychiatric disorders such as a major depressive episode, an anxiety disorder or schizophrenia. Insomnia also is able to open a delirious disorganization or a manic access. Psychological factors: overstimulation of waking system (related to stress overdose or intellectual hyperactivity), conditioning phenomena, fear of not falling asleep, intrapsychic and interpersonal conflicts. Third, the author put hypothesis about psychodynamic etiology of chronic insomnia. Following a first assumption, insomnia should be a result of anguish excess related to intrapsychic (and not interpersonal) conflicts which can't lead to a mental elaboration. These conflicts run over dream protective function, generating a breakdown of dream symbolization function. At a clinical level, we are in some cases in front of people enduring sleeping insomnia but more often, we are confronted with an intermittent or early waking insomnia sometimes associated with nightmares. Following a second assumption, insomnia should be a result of psychic functioning invalidation. Here, failure of dream protective and symbolization function is related to anguish excess associated with an amount of external conflicts. Overwhelmed by concretude, insomniac patients present an alexythimic intrapsychic functioning forbiding dream realization. These persons have no possibility to elaborate conflicts especially external overcharge, using dreams or imagination to escape from an intrusive reality and regress to sleeping. Here we are in front of initial sleep insomnia. Following a third hypothesis, some insomnias are related to wakings associated with repetitive nightmares. This type of insomnia should be related to a past traumatic event or activated by actual existential context and produces a too important anguish charge to follow a mental elaboration process and lead to mental symbolic representation. Following a fourth hypothesis, some insomnias are in relation with an impossibility to accept passive position. The last one will expose to a danger consisting either of castration or loneliness and death. To conclude, the author suggests some preventive perspective to face insomnia. Especially, she points out limits of pharmalogical treatments. She underlines the necessity to promote no medical methods to facilitate sleep induction and maintenance, including sleep hygiene measures, relaxation, psychotherapic approach and behavioral methods. She emphasizes the danger of a reductive approach of insomnia which would be focused on a single medical, psychological or environmental dimension. Last but not least, she makes methodological propositions to test from a clinical point of view the four psychodynamic exposed hypotheses.

A prospective study was carried out in the only tertiary oncology department in Oman to analyse the pattern of various prognostic factors in terminally ill cancer patients and their impact on these patients. Between September 1999 and February 2001, terminally ill cancer patients with solid tumours who fulfilled the eligibility criteria were included. All of them were coded Do Not Resuscitate (DNR). Clinical estimation of survival as well as recording of different symptoms and signs was carried out for each patient. Survival was calculated from the date of the DNR coding to the date of death. A total of 162 patients were included. Mean survival time was 41.5 days (median 10 days). The gastrointestinal tract (GIT) was the most common site of malignant disease, followed by the breast. Univariate analysis of evaluable patients showed that performance status (PS), dry mouth, presence of delirium, anorexia, peripheral oedema, absence of bone metastasis, low lymphocyte count and low albumin level had significant effects on survival. Multiple regression analysis showed that PS and oedema were the only independent predictors of survival. Clinical prediction of survival was correlated with observed survival. Patient's PS, presence of peripheral oedema and clinical estimate of survival are good predictors of survival in terminally ill cancer patients.

Advanced cancer patients are polysymptomatic and often receive multiple medications for symptom relief. Common symptoms include anorexia, weight loss, delirium and depression. Olanzapine and mirtazapine may have several advantages over older agents despite increased acquisition costs. Both medications can treat several symptoms with a low risk for drug-drug interactions and with only once- or twice-daily dosing. Drug side effects are low, compared with more conventionally used agents. The pharmacokinetics and pharmacodynamics of both agents are unique and explain many of the benefits. More research and clinical experience will be necessary to define their role in the palliation of advanced cancer.

Recombinant preparations of the cytokine interferon (IFN)-alpha are increasingly used to treat a number of medical conditions, including chronic viral hepatitis and several malignancies. Although frequently effective, IFN alpha induces a variety of neuropsychiatric adverse effects, including an acute confusional state that develops rapidly after initiation of high-dose IFN alpha, a depressive syndrome that develops more slowly over weeks to months of treatment, and manic conditions most often characterised by extreme irritability and agitation, but also occasionally by euphoria. Acute IFN alpha-induced confusional states are typically characterised by disorientation, lethargy, somnolence, psychomotor retardation, difficulties with speaking and writing, parkinsonism and psychotic symptoms. Strategies for managing delirium should be employed, including treatment of contributing medical conditions, use of either typical or atypical antipsychotic agents and avoidance of medications likely to worsen mental status. Significant depressive symptoms occur in 21-58% of patients receiving IFN alpha, with symptoms typically manifesting over the first several months of treatment. The most replicated risk factor for developing depression is the presence of mood and anxiety symptoms prior to treatment. Other potential, but less frequently replicated, risk factors include a past history of major depression, being female and increasing IFN alpha dosage and treatment duration. The available data support two approaches to the pharmacological management of IFN alpha-induced depression: antidepressant pretreatment or symptomatic treatment once IFN alpha has been initiated. Pretreatment might be best reserved for patients already receiving antidepressants or for patients who endorse depression or anxiety symptoms of mild or greater severity prior to therapy. Several recent studies demonstrate that antidepressants effectively treat IFN alpha-induced depression once it has developed, allowing the vast majority of subjects to complete treatment successfully. Recent data suggest that IFN alpha-induced depression may be composed of two overlapping syndromes: a depression-specific syndrome characterised by mood, anxiety and cognitive complaints, and a neurovegetative syndrome characterised by fatigue, anorexia, pain and psychomotor slowing. Depression-specific symptoms are highly responsive to serotonergic antidepressants, whereas neurovegetative symptoms are significantly less responsive to these agents. These symptoms may be more effectively treated by agents that modulate catecholaminergic functioning, such as combined serotonin-noradrenaline (norepinephrine) antidepressants, bupropion, psychostimulants or modafinil. Additional factors to consider in selecting an antidepressant include potential drug-drug interactions and adverse effect profile. Finally, IFN alpha appears capable of inducing manic symptoms. Mania, especially when severe, is a clinical emergency. When this occurs, IFN alpha and antidepressants should be stopped, an emergency psychiatric consultation should be obtained, and treatment with a mood stabilizer should be initiated.

A 69-year-old woman caught a cold resulting in nausea, vomiting, diarrhea and severe anorexia. Then she suffered progressively from dyspnea and leg edema, and finally became delirious. On admission severe hypoglycemia, hypothermia, marked tachycardia, generalized edema, mild jaundice and cachexy were noted. EKG showed atrial fibrillation. A chest X-ray, chest CT and echocardiography showed congestive heart failure. Therapeutic use of diuretics induced shock leading to serious liver dysfunction and disseminated intravascular coagulation. However, combined therapy by intravenous glucose, digitalis, diuretics, anti-fibrinolytic drug and hydrocortisone were effective. Addition of antithyroid therapy brought a further favorable outcome.

The key points of this article are anorexia and cachexia are: A major cause of cancer deaths. Several drugs are available to treat anorexia and cachexia. Dyspnea in cancer usually is caused by several factors. Treatment consists of reversing underlying causes, empiric bronchodilators, cortico-steroids--and in the terminally ill patients-opioids, benzodiazepines,and chlorpromazine. Delirium is associated with advanced cancer. Empiric treatment with neuroleptics while evaluating for reversible causes is a reasonable approach to management. Nausea and vomiting are caused by extra-abdominal factors (drugs,electrolyte abnormalities, central nervous system metastases) or intra-abdominal factors (gastroparesis, ileus, gastric outlet obstruction, bowel obstruction). The pattern of nausea and vomiting differs depending upon whether the cause is extra- or intra-abdominal. Reversible causes should be sought and empiric metoclopramide or haloperidol should be initiated. Fatigue may be caused by anemia, depression, endocrine abnormalities,or electrolyte disturbances that should be treated before using empiric methylphenidate. Constipation should be treated with laxatives and stool softeners. Both should start with the first opioid dose.
