Relationships Between Arousal-Related Moods and Episodic Tension-Type Headache: A Biopsychological Study

An exploratory study was conducted examining arousal-related moods and episodic tension-type headache. Twelve subjects meeting International Headache Society criteria for episodic tension-type headache and 12 headache-free controls recorded headache activity and mood eight times daily for 14 consecutive days. Moods were measured using the Activation-Deactivation Adjective Check List, a self-report list that subjectively represents general arousal along two dimensions of Tension and Energy. Headache subjects had higher Tension levels than controls even in the absence of pain, and greater variation in this dimension as well. Within the headache group, Tension during pain-free periods was significantly lower than when experiencing headache, and was correlated with headache activity. The results were taken to support Thayer's (1989) biopsychological model of mood and arousal, and are discussed in terms of the model's heuristic value for general arousal and headache research.     

Tuberculosis in East Sussex. I. Outbreaks of tuberculosis in cattle herds (1964-1984)

The history and epidemiology of bovine tuberculosis in cattle herds in East Sussex are described. Since 1960, following the compulsory eradication scheme for tuberculosis, the incidence of herd infection has been low. The epidemiological features of herd infection have been sporadic incidents, with only small numbers of cattle becoming infected in the majority of incidents. There was no evidence of endemic Mycobacterium bovis infection in the cattle population in East Sussex in recent years, but a low risk of infection for cattle on the South Downs, from badgers, was apparent.     

创伤后迟发性脑肿胀的临床特点与治疗

目的 探讨创伤后迟发性脑肿胀的临床特点、发病机制与治疗。方法 回顾性分析1998年1月～2005年6月年收治的17例迟发性脑肿胀患者的临床特点和救治情况。结果 所有颅脑损伤患者采用保守治疗后均有好转，但于伤后5-10d出现恶化，CT复查有脑肿胀，经加强综合脱水等治疗后16例治愈，1例死亡。结论 迟发性脑肿胀好发于对冲性额、颞叶挫裂伤伴明显蛛网膜下腔出血、硬膜下薄层血肿及早期CT有脑肿胀者。其发病机制可能与创伤后的迟发性脑血管痉挛、微循环障碍、静脉回流障碍及甘露醇作用下降等因素有关。此类患者病情隐蔽性强，应加强观察、积极行CT复查，如能早期明确诊断，保守治疗多数效果良好。     

Retrorenal colon: implications for percutaneous diskectomy

It has been recommended that computed tomography (CT) with the patient prone be performed in every patient undergoing percutaneous diskectomy; this would enable detection of a retrorenal location of the colon, which could interfere with the percutaneous procedure. In this evaluation of 346 prone CT studies, only one patient (0.29%) was found to have retrorenal or retropsoas bowel that would have been perforated at diskectomy. Because of this extremely low prevalence, the performance of prone CT in every patient undergoing percutaneous lumbar diskectomy is not believed to be necessary.     

Depression and smoking in pregnancy in Scotland.

OBJECTIVE--The aim was to examine the association between depressive symptoms and smoking in pregnancy and to investigate the part played by social and psychosocial factors. SETTING--A single Glasgow hospital. DESIGN--Prospective survey by postal questionnaires at 20 and 30 weeks' gestation. PARTICIPANTS--A total of 395 women (69% of the 572 eligible) parity 1 who booked for delivery between November 1988 and February 1990 took part. MEASUREMENTS--Depressive symptoms were measured using the Hospital Anxiety and Depression Scale. Smoking was self reported. The Life Events Inventory and measures of role specific strain and stress in domestic roles were used to assess psychosocial well being. MAIN RESULTS--Smokers were more likely than non-smokers to experience depressive symptoms at 20 and 30 weeks' gestation and on both occasions. The excess risk remained substantial and significant after adjustment for social and psychosocial factors. CONCLUSIONS--Smoking is a significant risk factor for depression in pregnancy. The association of smoking with depression and psychosocial difficulty represents a major problem for interventions intended to reduce smoking in pregnancy.
