  • Psychosocial Withdrawal characteristics of nicotine compared with alcohol and caffeine.
    Annals of the New York Academy of Sciences, 2008
    Co-Authors: Hisatsugu Miyata, Naoyuki Hironaka, Kohji Takada, Katsumasa Miyasato, Koichi Nakamura, Tomoji Yanagita
    Abstract:

    The purpose of the present study was to observe the Psychosocial characteristics of Withdrawal from cigarette smoking in comparison with those from caffeine (CAF) and alcoholic (ALC) beverage Withdrawal. Twenty-seven healthy volunteers at a medial level of dependence on both cigarettes (nicotine, NCT) and either CAF or ALC, as judged by the DSM-IV-TR criteria for substance dependence, participated in this study. The participants were required to abstain from smoking and either CAF or ALC for 7 days, each one after another, with a 7-day interval. The order of abstinence was counterbalanced among the participants. Psychosocial parameters, including a desire for substances, social activity function, well-being, Withdrawal symptoms, and vital signs, were assessed during the Withdrawal periods. The study protocol was approved by the Jikei University Review Board. The results indicated that there were no differences in the maximum level of desire for a substance and the influence on social activity function between NCT and other substances during the Withdrawal periods. As for Withdrawal symptoms, NCT caused a more intensive degree of irritability than CAF or ALC, and a more intensive degree of difficulty concentrating and restlessness than did Withdrawal from ALC. However, the subjective well-being questionnaire indicated no differences in these symptoms between NCT and other substances. The present results suggest that there are no significant differences in Psychosocial manifestations regarding the difficulty in abstaining from NCT, CAF, and ALC.

  • Malignant catatonia secondary to sporadic encephalitis lethargica
    Journal of neurology neurosurgery and psychiatry, 2000
    Co-Authors: Holly A. Shill, Mark Stacy
    Abstract:

    Catatonia is a neuropsychiatric syndrome characterised by a combination of Psychosocial Withdrawal and various movement disorders. Kahlbahm first described this syndrome in 1868 when he noted this condition of “profound mental anguish”. In 1893, Kraeplin limited catatonia to a subtype of dementia praecox, later redefined by Bleuler in 1906 as catatonic schizophrenia. Since then, it has become increasingly apparent that the catatonic syndrome can be seen not just in schizophrenia, but in affective disorders as well as secondary to various underlying medical conditions, leading the DSM-IV to broaden its categorisation of catatonia to include these other entities. In the early 1900s, a condition known variously as epidemic encephalitis, encephalitis lethargica, or Von Economo's disease was described, affecting more than 65 000 patients from 1919 to 1929.1Case descriptions reported during this time bear striking similarities to our modern definitions of catatonia. Throughout recent years, isolated cases of encephalitis lethargica have been reported.2 3 We present a patient with features of sporadic encephalitis lethargica and discuss management of this entity in the context of catatonia. The patient was a 22 year old previously psychologically and neurologically healthy woman who was transferred to the Barrow Neurological Institute after a 4 week stay in hospital for progressive immobility, mutism, posturing, and tremor. Initial evaluation had shown a CSF lymphocytosis, increased …
