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.     

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.     

Bronchoscopy for aspirated foreign bodies in children. Experience in 131 cases

One hundred thirty-one children underwent rigid bronchoscopy under general anesthesia for suspected aspirated foreign bodies. There were 79 boys and 52 girls, with a mean age of 2.1 years. Physical examination showed decreased breath sounds (n = 130) and wheezing (n = 119) over the affected site. Chest roentgenograms were diagnostic or suggestive of aspirated foreign bodies in 127 cases (97%). Radiopaque lesions were noted on roentgenograms in ten cases. Four infants had a preoperative hypoxic arrest. Two patients had negative results of bronchoscopy (1.5%). Extraction of the aspirated foreign body was carried out at laryngoscopy in two patients and by forceps under direct vision at bronchoscopy in 97 patients. A Fogarty catheter was used in 12 cases. Postendoscopic complications included fever (n = 27), pulmonary infiltrate (n = 11), ventilatory support (n = 4), and pneumothorax (n = 2). Rigid bronchoscopy for aspirated foreign body in children is a safe, effective, and sometimes life-saving procedure. Morbidity is low and mortality is zero.     

Rationally designed "dipeptoid" analogues of CCK. Acid mimics of the potent and selective non-peptide CCK-B receptor antagonist CI-988.

This paper outlines the synthesis of selected acid mimics of the non-peptide CCK-B selective antagonist CI-988, 1. CCK-B and CCK-A binding affinities of these analogues are described and their CCK-B affinity and selectivity rationalized by consideration of the pK(a) values, charge distribution, and geometry of the respective acid mimics. Several of the compounds have CCK-B binding affinities similar to the parent carboxylic acid 1 (CCK-B, IC50 = 1.7 nM; pK(a) = 5.6) and span a pK(a) range of less than 1 (sulfonic acid 27) to greater than 9.5 (5-thio-1,2,4-triazole 24). Among the more active compounds synthesized are tricyclo[3.3.1.1(3,7)]dec-2-yl [R-(R*,R*)]-[2-[[2-[[(3-hydroxy-5-isoxazolyl)acetyl]-amino]-2- phenylethyl]amino]-1-(1H-indol-3-ylmethyl)-1-methyl-2-oxoethyl+ ++]carbamate (15), tricyclo[3.3.1.1(3,7)]dec-2-yl [R-(R*,R*)]-[1-(1H-indol-3-ylmethyl)-1-methyl-2-oxo-2-[[2-[(1-oxo- 3-sulfopropyl)amino]-2-phenylethyl]amino]-ethyl]carbamate, monosodium salt (27), and tricyclo[3.3.1.1(3,7)]dec-2-yl [R-(R*,R*)]-[1-(1H-indol-3-ylmethyl)-1- methyl-2-oxo-2-[[2-[[(1H-1,2,4-triazol-5-ylsulfinyl)acetyl]a mino]-2-phenylethyl]amino]ethyl]carbamic acid (34) which have CCK-B binding affinities of IC50 = 2.6, 1.3, and 1.7 nM, CCK-A/-B ratios of 650, 780, and 550 and pK(a) values of 6.5, less than 1, and 7.0, respectively.
