1/96. nicotine dependence and withdrawal in an oncology setting: a risk factor for psychiatric comorbidity and treatment non-adherence.Highly nicotine dependent oncology patients are at high risk for psychiatric morbidity when they enter the medical care setting where smoking restrictions apply. nicotine withdrawal symptoms exacerbate cancer-related distress as well as common physical side effects of cancer treatment. This case report illustrates the management of a patient whose ongoing treatment for bladder cancer was jeopardized as a result of nicotine dependence and withdrawal. Several associated complications are described, the most serious of which were his acute anxiety and non-adherence to medical recommendations. A short-term management approach that included anxiolytics and nicotine replacement was effectively used to reduce this patient's excessive anxiety and thus facilitate compliance with stressful treatments. The severity of complications that can result from untreated nicotine dependence and withdrawal underscores the importance of assessing and monitoring smoking status in every patient. Greater staff awareness of the clinical practice guidelines regarding the diagnosis and treatment of nicotine dependence will likely result in improved patient care and compliance.- - - - - - - - - - ranking = 1keywords = anxiety (Clic here for more details about this article) |
2/96. clozapine-olanzapine: a potentially dangerous switch. A report of two cases.BACKGROUND: Withdrawal symptoms associated with switch between two typical antipsychotics are generally rare and mild. In contrast, switching from clozapine to risperidone can be lead to severe withdrawal symptoms. Different pathophysiologic aetiologies have been suggested for explaining these severe symptoms, including cholinergic supersensitivity and rebound. Theoretically, the switch from clozapine to olanzapine should not lead to any problems because those two agents have the same affinity in vitro for muscarinic receptors. OBJECTIVE: This study reports two cases of switches from clozapine to olanzapine, in refractory schizophrenic patients, which were associated with severe withdrawal symptoms. RESULTS: After the switch, the two patients developed diaphoresis, hypersialorrhea, bronchial obstruction, agitation, anxiety and enuresis. The symptoms were treated with anticholinergic medication and by an increase in dose of olanzapine to 20 mg/day. For one of the patients this treatment led to normalization of secretion. For the other patient, a superinfection leading to a bilateral pneumopathy which required emergency hospitalization in a general hospital was observed. CONCLUSION: The symptomatology and the response to treatment lead to the hypothesis of a muscarinic from abrupt weaning. The withdrawal symptoms disappeared rapidly with an increase in olanzapine dosage and with anticholinergic started at the beginning of the switch. We recommend slow clozapine weaning over 3 weeks or more with concurrent anticholinergic treatment.- - - - - - - - - - ranking = 0.5keywords = anxiety (Clic here for more details about this article) |
3/96. A case of seizures 1 week after the cessation of interferon-alpha therapy.We report on a 60-year-old woman with a history of bipolar mood disorder who had seizures and developed a delirious state 1 week after the cessation of interferon-alpha (IFN-alpha) for chronic hepatitis c. The IFN-alpha was administered to the patient for 7 weeks (266 million IU). One week after the cessation of IFN-alpha therapy, the patient had four generalized tonic-clonic seizures over a 2-day period and developed a delirious state for 2 months. We consider these seizures and delirious state to be related to IFN-alpha.- - - - - - - - - - ranking = 0.00049707283534243keywords = state (Clic here for more details about this article) |
4/96. A syndrome of psychosis following discontinuation of an estrogen-progestogen contraceptive and improvement following replacement: A case report.Mild forms of psychosis associated with low estrogen levels during the perimenopause are relatively frequent. There is scarce data on severe forms of psychosis in these conditions. We report the case of a 51-year-old woman with no previous psychiatric history who amputated her hand in a 'psychotiform' state after discontinuation of her contraceptive medication. Having subsequently jumped out of a window, she suffered a fracture of the dens with central spinal cord injury and symptoms of cruciate paralysis. The patient stabilized under a combined therapy with estrogen-progestogen substitution, antipsychotic medication and add-on oxcarbazepine.- - - - - - - - - - ranking = 0.00016569094511414keywords = state (Clic here for more details about this article) |
5/96. Substance abuse and emergency psychiatry.Given the high rates of comorbidity, patients commonly present with multiple diagnoses to PESs or crisis services. Clinicians must be well versed in the evaluation, differential diagnosis, and treatment of patients with substance-abuse disorders or other axis I, II, or III conditions if they are to provide state-of-the-art treatment of patients in need of emergency care.- - - - - - - - - - ranking = 0.00016569094511414keywords = state (Clic here for more details about this article) |
6/96. Catatonialike symptomatology and withdrawal dyskinesias.The authors describes a patient who presented catatonialike symptoms and dyskinesias associated with glutethimide discontinuance and antihistamine use. He hypothesizes that altered dopamine metabolism may produce some of the unusual neuropsychiatric characteristics of glutethimide withdrawal. Drug-withdrawal catatonia may be an additional entity in the differential diagnosis of catatonialike states of organic etiology.- - - - - - - - - - ranking = 0.00016569094511414keywords = state (Clic here for more details about this article) |
7/96. Undetectable prostate-specific antigen response with bicalutamide withdrawal phenomenon.Several reports have described the antiandrogen withdrawal syndrome with various nonsteroidal antiandrogen agents. To our knowledge, there have been no reports describing a durable undetectable prostate-specific antigen (PSA) response with discontinuation of the antiandrogen agent bicalutamide (Casodex, Zeneca, Wilmington, DE, U.S.A.). We report a case in which a decline of serum PSA to undetectable levels was achieved with bicalutamide discontinuation.- - - - - - - - - - ranking = 0.00082845472557072keywords = state (Clic here for more details about this article) |
8/96. Insomnia related to biperiden withdrawal in two schizophrenic patients.It is not uncommon for patients who are receiving antipsychotic medication to be given anticholinergic agents, such as biperiden, despite the relative absence of neurological side-effects. Two cases of schizophrenia are reported in which insomnia developed after biperiden withdrawal or reduction. The insomnia continued until biperiden treatment was reinstated, despite the fact that the patients did not exhibit signs or report symptoms indicative of antipsychotic drug-induced neurological side-effects. The occurrence of insomnia following the withdrawal of biperiden or reduction in the dose has not been previously reported. One potential explanation for the insomnia is cholinergic rebound following the withdrawal of biperiden.- - - - - - - - - - ranking = 0.00016569094511414keywords = state (Clic here for more details about this article) |
9/96. Gamma-hydroxybutyrate withdrawal syndrome.STUDY OBJECTIVE: Gamma-hydroxybutyrate (GHB) withdrawal syndrome is increasingly encountered in emergency departments among patients presenting for health care after discontinuing frequent GHB use. This report describes the characteristics, course, and symptoms of this syndrome. methods: A retrospective review of poison center records identified 7 consecutive cases in which patients reporting excessive GHB use were admitted for symptoms consistent with a sedative withdrawal syndrome. One additional case identified by a medical examiner was brought to our attention. These medical records were reviewed extracting demographic information, reason for presentation and use, concurrent drug use, toxicology screenings, and the onset and duration of clinical signs and symptoms. RESULTS: Eight patients had a prolonged withdrawal course after discontinuing chronic use of GHB. All patients in this series were psychotic and severely agitated, requiring physical restraint and sedation. Cardiovascular effects included mild tachycardia and hypertension. Neurologic effects of prolonged delirium with auditory and visual hallucinations became episodic as the syndrome waned. Diaphoresis, nausea, and vomiting occurred less frequently. The onset of withdrawal symptoms in these patients was rapid (1 to 6 hours after the last dose) and symptoms were prolonged (5 to 15 days). One death occurred on hospital day 13 as withdrawal symptoms were resolving. CONCLUSION: In our patients, severe GHB dependence followed frequent ingestion every 1 to 3 hours around-the-clock. The withdrawal syndrome was accompanied initially by symptoms of anxiety, insomnia, and tremor that developed soon after GHB discontinuation. These initial symptoms may progress to severe delirium with autonomic instability.- - - - - - - - - - ranking = 0.5keywords = anxiety (Clic here for more details about this article) |
10/96. Restlessness related to SSRI withdrawal.There are reports that abrupt withdrawal of various selective serotonin re-uptake inhibitors, such as fluvoxamine, can elicit in patients various withdrawal symptoms. fluvoxamine has been widely used in japan for approximately 1 year. However, there have been no case reports of withdrawal symptoms following abrupt fluvoxamine discontinuation in japan. The author reports a case where the abrupt discontinuation of fluvoxamine produced restlessness in a depressed patient. The restlessness disappeared soon after the reinstatement of treatment with fluvoxamine. This case report suggests that clinicians should carefully scrutinize a patient's compliance to fluvoxamine as the withdrawal symptoms observed following abrupt discontinuation might be regarded as a relapse of depression or side-effects of the medicine.- - - - - - - - - - ranking = 0.00016569094511414keywords = state (Clic here for more details about this article) |
