Familial Sneddon's syndrome

We report the familial occurrence and apparent autosomal dominant inheritance of Sneddon's syndrome with variable clinical expression. The proband, a 40-year-old woman, presented with livedo reticularis and progressive neurological deterioration following a stroke. The diagnosis was confirmed by cerebral angiogram and skin biopsy, both showing the characteristic findings. Two of the patient's sisters were reported to have been similarly affected in the past. Her mother, two additional siblings and five of her seven children exhibited various vasospastic skin phenomena. Familial aggregation of this disorder may be common and a genetic basis may be involved in its pathogenesis.

Identifying patients at risk for,and treatment of major psychiatric complications of cancer

A critically important aspect of supportive care in cancer is the prompt recognition and effective treatment of psychiatric complications. Psychiatric disorders such as depression, anxiety and delirium occur in a signifcant percentage of cancer patients, particularly as disease advances and as cancer treatments become more aggressive. This paper reviews factors that can be utilized to identify patients who are at increased risk for developing psychiatric complications, such as those with advanced disease, certain cancer treatments, uncontrolled physical symptoms, functional limitations, lack of social support, and past history of psychiatric disorder. Methods of diagnostic assessment and strategies for managing depression, anxiety, delirium and suicidal ideation are also reviewed.Presented as an invited lecture at the 6th International Symposium: Supportive Care in Cancer, New Orleans, La., USA, 2–5 March 1994     

Digital movement analysis,a new objective method of measuring tardive dyskinesia and drug-induced parkinsonian tremor: acceptability,reliability and validity

Digital movment analysis (DMA) is a new instrumental approach to assessing oral tardive dyskinesia (TD) by means of digital image processing of a video signal, tracking five paper dots placed around the patient's mouth. A total of 40 schizophrenic patients, 30 with and 10 without TD, were examined twice (with a 3-month interval) with this new device. The patients were further examined with two TD rating scales: the St. Hans Rating Scale for extrapyramidal syndromes (SHRS) and the Abnormal Involuntary Movement Scale (AIMS).The schizophrenic patients accepted the instrumental assessment without any anxiety or resistance. The internal relibility of the apparatus was high, with correlation coefficients of 0.80–0.99. The DMA TD values correlated with the SHRS and AIMS scores with correlation coefficients of 0.48–0.73 indicating an acceptable, although not strong, concurrent validity. Fluctuations occurred from the first to the second examination independent of medication. For these fluctuations no correlation was found between DMA values and rating scores. Finally, the DMA device was able to detect perioral tremor as a sign of parkinsonism.It has been concluded that DMA is a useful supplement to classical TD rating, although further validity evaluation is warranted.     

MHPG and heart rate as correlates of nonresponse to drug therapy in panic disorder patients

Little is known about biological predictors of treatment response in panic disorder (PD). In the present study heart rate, blood pressure, plasma cortisol and plasma MHPG were investigated at baseline in a sample of 44 PD patients as possible predictors for nonresponse to treatment. We used a strict definition of nonresponse to find patients who did not respond at all after 12 weeks of treatment with brofaromine or fluvoxamine. Patients were considered nonresponders when they fulfilled two criteria: they did not show a 50% reduction of agoraphobic avoidance and they still experienced panic attacks at endpoint. The variables that differed significantly between the groups were used to predict nonresponse to drug therapy. Using this strict definition of nonresponse, 15 patients (32.6%) were considered nonresponders. These patients were characterised by a higher plasma MHPG concentration and a higher heart rate at baseline. These variables were subsequently used to predict nonresponse.     

帕罗西汀对抑郁模型大鼠不同脑区环磷酸腺苷反应元件结合蛋白的影响

目的探讨帕罗西汀在不同用药时间对抑郁模型大鼠海马、前额叶皮质环磷酸腺苷反应元件结合蛋白（CREB）磷酸化（p-CREB）及总蛋白（t-CREB）水平的影响。方法成年雄性SpragueDawley大鼠36只，随机分为6组：对照组、抑郁模型组（以下简称模型组）、抑郁模型＋用药1d组（以下简称用药1d组）、抑郁模型＋用药1周组（以下简称用药1周组）、抑郁模型＋用药2周组（以下简称用药2周组）和抑郁模型＋用药4周组（以下简称用药4周组），每组各6只。抑郁模型的制作为强迫大鼠游泳4周，每天1次，每次15min。帕罗西汀的剂量为10m∥kg体质量，灌胃给药，时间分别为1d和1，2，4周，每天1次，于每次游泳前用药。采用Westernblot法检测各组大鼠海马及前额叶皮质的p-CREB和t-CREB水平。结果（1）模型组及用药1d、1周组大鼠海马p-CREB水平明显低于对照组（P〈0．01），用药2，4周组大鼠海马p-CREB水平与对照组的差异无统计学意义（P〉0．05）；模型组及各用药组海马t-CREB水平与对照组的差异无统计学意义（P〉0．05）。（2）模型组及用药1d和1，2周组大鼠前额叶皮质p-CREB水平均明显低于对照组（P〈0．05），用药4周组与对照组的差异无统计学意义（P〉0．05）。模型组及用药1d、1周组大鼠前额叶皮质t-CREB水平与对照组的差异无统计学意义（P〉0．05），用药2，4周组大鼠前额叶皮质t-CREB水平均明显高于对照组（P〈0．05或P〈0．01）。结论慢性强迫游泳导致大鼠海马及前额叶皮质CREB活性降低，长期使用帕罗西汀可逆转此效应，提高抑郁大鼠前额叶皮质的CREB水平。     

抑郁障碍患者人格特征与发病关系的研究

目的探讨抑郁障碍患者的人格特征与其疾病发病间的关系。方法采用自评抑郁量表(SDS)、艾森克人格问卷 (EPQ)、应对方式评定量表 (WCRS)和归因方式问卷 (ASQ)对 76名抑郁障碍患者进行测试 ,同时选取 84名健康被试进行对照研究。结果①抑郁组患者在EPQ中神经质 (N)与精神质 (P)的得分显著高于健康组。②WCRS的结果显示在“宣泄接纳”、“退避调节”两个因子上 ,抑郁组的平均得分低于健康组。③在ASQ的得分中 ,抑郁组在负性事件归因的自身性、持久性和整体性均显著高于健康组。④抑郁障碍患者的“神经质”人格特质与应对方式的“宣泄接纳”和“退避调节”因子呈负相关 (r = 0 .474)。结论抑郁障碍患者的人格特征可表现为较强的神经质及孤僻、交往障碍 ,他们这种人格特征及应对和归因方式在其发病过程中起着重要作用。     

Psychiatrists' Use of Melatonin with Children

Background:  Melatonin is gaining popularity as a sedative agent with children. This study sought to characterise this practice more precisely as well as examine aspects of its safety and efficacy in order to develop treatment guidelines.
Method:  Postal surveys of two groups of psychiatrists: generic child psychiatrists and psychiatrists who regularly treat learning disabled children.
Results:  Both groups (all of the specialists and 81% of the non-specialists) reported regular but not frequent use of melatonin in their usual practice, mostly for night-settling sleep problems refractory to behavioural modification strategies, commonly in the context of neurodevelopmental disability (especially autism). Treatment was described as being 'usually successful' and side-effects were highly infrequent and mild in nature. Variations in most prescribing practices were identified (dosage, timing).
Conclusions:  Melatonin appears to represent a useful and relatively safe drug when used in specific circumstances; however, the evidence-base underpinning its use, particularly over the long-term, remains modest. Thus caution and clinical audit of practice is required.
