ABSTRACT
A patient developed persistent parkinsonism after intravenously injecting a high dose of methamphetamine. Magnetic resonance imaging revealed bilateral hypoxic/ischemic basal ganglia damage, which could have been caused by the vasoconstrictive effect of methamphetamine. This case adds some circumstantial evidence to the association between methamphetamine and Parkinsonism. Key words: Parkinsonism; methamphetamine; substance use disorders

ABSTRACT
Background The severity of difficulty in falling asleep and the insufficiency of the sleeping time in the primary insomniacs always were overestimated, even after medication and improving the objective sleep quality. Moreover, remarkable psychosomatic symptoms were found in patients and the symptoms were significantly linked to the self-reported sleep quality. So in this study, it was designed to explore the differences between objective and subjective sleep quality and its correlative factors in chronic insomniacs.Methods A total of 55 chronic primary insomniac cases diagnosed by DSM-Ⅳ diagnostic criteria for primary insomnia and 15 normal controls were rated with Pittsburgh sleep quality index (PSQI),State-Trait Anxiety Inventory (STAI), and the Subjective General Condition Form. All cases and the controls were then examined by the whole-night polysomnography (PSG) records.Results Compared with the objective parameters of PSG, the subjective parametersiu chronic insomniacs had significantly longer sleep latency and lower total sleep time and sleep efficiency [ (80. 3± 73.7)min v.s. (23.2 ± 25.4) min, (157.8±141.7)min v.s. (332.2±154.7)min , (0.52 ±0. 27) min v.s. (0. 67 ± 0. 28) min, respectively, P ＜0. 001 ]. The difference between subjective and objective sleep latency was related to the total scores of STAI, TAI and SAI ( r = 0. 402,0. 374 and 0. 397, respectively, P ＜ 0. 05).Conclusions There were significant differences between objective and subjective estimations of sleep quality in chronic insomniacs,and they might result in the overestimation of the severity of insomnia. The differences between subjective and objective sleep quality in the chronic insomniacs were significantly correlated with the levels of anxiety.
ABSTRACT
Background During the past two decades, a number of rating scales were developed to facilitate diagnosis and assessment of subjects with social anxiety disorder. One of the most commonly used scales for the assessment of social anxiety disorder is the Liebowitz social anxiety scale (LSAS). The LSAS is widely used in epidemiologic investigations and clinical researches,and its assessment in the pharmacotherapy efficacy for social anxiety disorder is superior to any other scale. So we designed this study to explore the validity and reliability of the LSAS in Chinese patients with social anxiety disorder and normal control, and to find the difference of the scores between the patients self -report version and clinician-administered version. Methods Fifty five patients meeting the DSM-Ⅳ diagnostic criteria for social anxiety disorder and 168 normal controls who were screened from 222 college students were rated by LSAS, social phobia scale and self-made General Information Forms. Results The Cronbath α of LSAS for the patients and the normal controls was 0.83 and 0.77, respectively. The 4-week test-retest reliability for total scores and its factors scores of LSAS in 31 normal controls were ranging from 0.68 to 0.79. The ROC area under curve value in discriminating the patients from normal controls was 0.87±0.03; the total score of 35 was considered to be the best cut-off score for LSAS, then its sensitivity was 0.77 and its specificity was 0.81; and no significant difference between the self-report version and clinician-administered version. Conclusions The LSAS is good in internal consistency and test-retest reliability, and has high sensitivity and specificity in discriminating the patients and the controls. There is no significant difference in the total score and each factor scores of LSAS between self-report version and clinician-administered version.
ABSTRACT
Comparing the Psychiatry teaching among Jinan University,Sum-Yan-San University and The Chinese University of Hong Kong,we found the time,contents and methods of teaching were significantly different among them,so we suggested that Jinan University should reconstruct teaching mode,raise teaching time,optimize teaching contents,change practice teaching methods and examination way in psychiatry teaching.
ABSTRACT
Objective : To investigate the incidence of Restless Legs Syndrome (RLS) in pregnant women and the effect of the RLS on the sleep quality of the women during pregnancy. Methods: 113 pregnant women were evaluated by using International RLS Scale, PSQI (Pittsburg Sleep Quality Inventory). Results: The prevalence of RLS in pregnant women in the outpatient department was 12.4% (14/113), the percentage of RLS pregnant women with PSQI total score higher than 7 was 28.6%, and that was 10.1% in the pregnant women without RLS (x2 =3.86,P
ABSTRACT
0.05).Conclusions: (1) The more severe of learning stress, the higher level of PMDD. (2) There was no difference in anxiety and depression between the students who suffered from PMDD and the who didn't. (3) The students who suffered from PMDD had more psychosomatic symptoms.
ABSTRACT
Objective:To understand the sleep duration, sleep habits, the prevalence rate of sleep problem and its related factors on the children range from 4 to 12 years old. Methods:The parents of 727 children range from 4 to 12 years old were asked to answer The Children's Sleep Habits Questionnaire (CSHQ) and the general information forms, which were used to rate their children.Results:The average sleep time on bed of the children was 9.6?0.9 hours, with no difference between males and females. The total scores of CSHQ were 36.8?13.6, and the prevalence of sleep problem was 31.0%. The total scores of CSHQ among 4-6 years old group, 7-9 years old group and 10-12 years old group were significant different (42.4?14.1?34.9?12?31.8?12, respectively ;P
