Selected AbstractsA review of the clinical pharmacology of methamphetamineADDICTION, Issue 7 2009Christopher C. Cruickshank ABSTRACT Aims To examine the literature regarding clinical pharmacokinetics, direct effects and adverse clinical outcomes associated with methamphetamine use. Methods Relevant literature was identified through a PubMed search. Additional literature was obtained from relevant books and monographs. Findings and conclusions The mean elimination half-life for methamphetamine is approximately 10 hours, with considerable inter-individual variability in pharmacokinetics. Direct effects at low-to-moderate methamphetamine doses (5,30 mg) include arousal, positive mood, cardiac stimulation and acute improvement in cognitive domains such as attention and psychomotor coordination. At higher doses used typically by illicit users (,50 mg), methamphetamine can produce psychosis. Its hypertensive effect can produce a number of acute and chronic cardiovascular complications. Repeated use may induce neurotoxicity, associated with prolonged psychiatric symptoms, cognitive impairment and an increased risk of developing Parkinson's disease. Abrupt cessation of repeated methamphetamine use leads to a withdrawal syndrome consisting of depressed mood, anxiety and sleep disturbance. Acute withdrawal lasts typically for 7,10 days, and residual symptoms associated with neurotoxicity may persist for several months. [source] Progressive dementia caused by Hashimoto's encephalopathy , report of two casesEUROPEAN JOURNAL OF NEUROLOGY, Issue 10 2004J. Spiegel Dementia induced by Hashimoto's encephalopathy (HE) seems to be a rare condition. We report on two patients, who revealed a syndrome consisting of a rapid progressive dementia with myocloni. In both patients, the detection of antithyroid antibodies enabled the diagnosis of HE. The symptoms receded completely during a high-dose glucocorticoid therapy. In patients with rapidly progressive dementia or with dementia of unknown origin, HE should be considered. [source] Migraine: A Chronic Sympathetic Nervous System DisorderHEADACHE, Issue 1 2004Stephen J. Peroutka MD Objective.,To determine the degree of diagnostic and clinical similarity between chronic sympathetic nervous system disorders and migraine. Background.,Migraine is an episodic syndrome consisting of a variety of clinical features that result from dysfunction of the sympathetic nervous system. During headache-free periods, migraineurs have a reduction in sympathetic function compared to nonmigraineurs. Sympathetic nervous system dysfunction is also the major feature of rare neurological disorders such as pure autonomic failure and multiple system atrophy. There are no known reports in the medical literature, however, comparing sympathetic nervous system function in individuals with migraine, pure autonomic failure, and multiple system atrophy. Methods.,A detailed review of the literature was performed to compare the results of a wide variety of diagnostic tests and clinical signs that have been described in these 3 heretofore unrelated disorders. Results.,The data indicate that migraine shares significant diagnostic and clinical features with both pure autonomic failure and multiple system atrophy, yet represents a distinct subtype of chronic sympathetic dysfunction. Migraine is most similar to pure autonomic failure in terms of reduced supine plasma norepinephrine levels, peripheral adrenergic receptor supersensitivity, and clinical symptomatology directly related to sympathetic nervous system dysfunction. The peripheral sympathetic nervous system dysfunction is much more severe in pure autonomic failure than in migraine. Migraine differs from both pure autonomic failure and multiple system atrophy in that migraineurs retain the ability, although suboptimal, to increase plasma norepinephrine levels following physiological stressors. Conclusions.,The major finding of the present study is that migraine is a disorder of chronic sympathetic dysfunction, sharing many diagnostic and clinical characteristics with pure autonomic failure and multiple system atrophy. However, the sympathetic nervous system dysfunction in migraine differs from pure autonomic failure and multiple system atrophy in that occurs in an anatomically intact system. It is proposed that the sympathetic dysfunction in migraine relates to an imbalance of sympathetic co-transmitters. Specifically, it is suggested that a migraine attack is characterized by a relative depletion of sympathetic norepinephrine stores in conjunction with an increase in the release of other sympathetic cotransmitters such as dopamine, prostaglandins, adenosine triphosphate, and adenosine. An enhanced understanding of the sympathetic dysfunction in migraine may help to more effectively diagnose, prevent, and/or treat migraine and other types of headache. [source] Aggressive behaviour and burnout among staff of homes for the elderlyINTERNATIONAL JOURNAL OF MENTAL HEALTH NURSING, Issue 1 2002Will Evers ABSTRACT: This study examines relationships between experienced aggressive behaviour and burnout of staff caring for residents living in homes for the elderly (n = 551). Burnout was conceptualized as a three-dimensional syndrome consisting of emotional exhaustion, depersonalization and reduced personal accomplishment. From the results of the hierarchical regression analyses it appeared that physical and psychological aggression and the number of weekly working hours had a significant relationship with emotional exhaustion of staff. Psychological aggression was found to have a significant relationship with depersonalization. Neither sex nor age had a relationship with any of the burnout dimensions. Implications for research and suggestions for work and training of staff caring for the elderly are discussed. [source] The basics behind bladder pain: A review of data on lower urinary tract sensationsINTERNATIONAL JOURNAL OF UROLOGY, Issue 2003J. J. WYNDAELE Abstract Interstitial cystitis is a syndrome consisting of frequency, urgency, and bladder pain that increases with bladder filling and improves temporarily after voiding. The exact cause or causes are not as yet fully understood. This leads to uncertainty in diagnosis and treatment. There is need for more knowledge, and to acquire this for more research. The fact that the condition causes pain, a pathologic stimulation of sensory fibres, makes understanding the basic sensory mechanisms in the lower urinary tract in normal and pathologic conditions mandatory. In this article we review the data on bladder sensation from the last 25 years and the possible relation with painful bladder syndrome. [source] Perioperative care of a patient with Beare,Stevenson syndromePEDIATRIC ANESTHESIA, Issue 12 2005SARA UPMEYER DO Summary Beare,Stevenson syndrome is a craniofacial syndrome consisting of a specific pattern of craniosynostosis resulting in a cloverleaf skull deformity and hydrocephalus, down-slanting palpebral fissures, proptosis, hypertelorism, strabismus, dysmorphic ears, choanal atresia, cleft palate, cutis gyratum, acanthosis nigricans, and abnormal genitalia. Its primary cause has been identified as a single amino acid substitution in fibroblast growth factor receptor 2. Of primary importance to the anesthesiologist are issues related to airway management resulting from midface hypoplasia, choanal atresia, and airway abnormalities (tracheal stenosis). Additional issues affecting airway management include associated cervical spine and foramen magnum abnormalities. The authors present their experience caring for a patient with Beare,Stevenson syndrome and discuss the anesthesia care of these patients. [source] Acquired ichthyosis associated with an overlap syndrome of systemic sclerosis and systemic lupus erythematosusTHE JOURNAL OF DERMATOLOGY, Issue 1 2006Hae-Woong LEE ABSTRACT Acquired ichthyosis is a condition accompanying many systemic illnesses such as lymphoma, sarcoidosis, dermatomyositis and systemic lupus erythematosus (SLE). Overlap syndromes are defined as clinical entities which satisfy each of the diagnostic criteria of two different connective tissue diseases concurrently or consecutively. The coexistence of SLE with systemic sclerosis has been very rarely reported. We describe a 33-year-old woman with an overlap syndrome consisting of systemic sclerosis and SLE who developed ichthyosis on her extremities. [source] | ||||||||||
