Twenty-one smokers underwent 24-h abstinence from cigarettes. Both prior to, and after, the abstinence period cardiovascular and subjective effects of smoking a cigarette were measured. Withdrawal symptoms found during abstinence were: irritability, depression, hunger, difficulty concentrating, restlessness and urges to smoke. In addition, the subjects reported feeling physically less well. Withdrawal discomfort was positively correlated with the strength of the subjective effects (e.g. dizziness, nausea) of smoking the post-abstinence cigarette after taking account of estimated nicotine boost from that cigarette. A similar, though only marginally significant association was found between withdrawal severity and heart rate boost from the post-abstinence cigarette. Our results suggest that the severity of withdrawal may be related to loss of acute tolerance to nicotine. It is not clear whether this is due to more rapid nicotine clearance, constitutional differences in sensitivity to nicotine in the absence of acute tolerance, or other factors. There was no evidence to support the view that higher chronic tolerance to nicotine's heart-rate effects was associated with more severe withdrawal. If anything, the reverse appeared to be the case.

To describe the effect of nonnutritive sucking (NNS) on behavioral state (BSt) in preterm infants before feedings 24 preterm infants were randomly assigned and studied before each of their first 16 bottle feedings. Twelve received NNS by pacifier for 5 minutes; 12 did not receive a pacifier. BSt was measured with a 12-category scale for 30 seconds before the 5-minute period (BSt1) and for 30 seconds after (BSt2). Sleep states decreased for both groups. BSts considered more optimal for feeding increased more during NNS (86 vs. 46). Restless states were three times less frequent after NNS (23 vs. 68). Differences between groups were nonsignificant at BSt1, but were significant at BSt2, p less than .001. In the absence of self-regulatory feeding policies based on early hunger cues, NNS for 5 minutes prefeeding is simple, brief, and suitable for implementation in busy neonatal intensive care units. Nonnutritive sucking was an effective modulator of behavioral state for this sample.

Ratings of withdrawal symptoms were obtained from 52 Smokers Clinic clients who abstained throughout a four week group treatment programme involving use of nicotine chewing gum. Mean ratings of irritability, depression, hunger, restlessness, and inability to concentrate were significantly higher in the first week of abstinence than at baseline, although only a minority of smokers experienced severe withdrawal symptoms. Disturbance of mood and concentration returned to baseline within four weeks while increases in hunger persisted. The average amount of time spent with the urge to smoke started to decline early in treatment, but the average strength of urges and overall difficulty not smoking did not decline until the fourth week. At the end of treatment 35% were still experiencing strong urges to smoke and 23% reported finding it difficult keeping themselves from smoking. The findings have practical implications for preparing smokers for cessation with the aid of nicotine gum.

Twenty-nine cigarette smokers completed a smoking motivation questionnaire and had expired-air carbon monoxide (CO) and plasma nicotine concentrations measured prior to abstaining from smoking for 24 h. Before and after the abstinence period, the subjects rated mood and physical symptoms known to be affected by cigarette abstinence (e.g. irritability, restlessness). Scores on the "dependent smoking" subscale of the smoking motivation questionnaire correlated significantly with overall withdrawal severity, craving, and increased irritability. "Indulgent smoking" scores correlated positively with increased hunger. Pre-abstinence plasma nicotine concentration significantly predicted craving, hunger, restlessness, inability to concentrate and overall withdrawal severity, while expired-air CO predicted craving and restlessness only. Usual daily cigarette consumption did not significantly predict any withdrawal effects. The data indicate that pre-abstinence measures of smoking motivation and smoke intake may provide a guide to withdrawal severity on smoking cessation and that smokers with a high pre-abstinence nicotine intake experience the greatest discomfort.

To test the validity, magnitude, and clinical significance of the signs and symptoms of tobacco withdrawal defined by DSM-III, both observed and reported signs and symptoms were measured in 50 smokers during two days of ad lib smoking and then during the first four days of abstinence. Observer and subject ratings of the DSM-III symptoms of craving for tobacco, irritability, anxiety, difficulty concentrating, and restlessness increased after cessation. In addition, bradycardia, impatience, somatic complaints, insomnia, increased hunger, and increased eating occurred after cessation. The frequency and intensity of these symptoms varied across subjects; however, the average distress from tobacco withdrawal was similar to that observed in psychiatric outpatients. Subjects who had more withdrawal discomfort were more tolerant to the cardiovascular effects of nicotine. Subjects who had more withdrawal discomfort did not have a lower rate of smoking cessation.

Croup syndromes are common in children, most frequently being infectious in origin. Children present with a slow progression of inspiratory and expiratory stridor and a croupy, "barking seal" cough. Children are variably febrile and with progression of disease, exhaustion, agitation, cyanosis and air hunger may develop. The evaluation of the patient must focus on the degree of respiratory distress and associated findings. Epiglottitis and foreign body aspiration must be excluded. Management is primarily dependent upon administration of humidified air. Children with moderate to severe croup benefit from racemic epinephrine and steroids. Admission is indicated in children with stridor at rest, evidence of exhaustion, toxicity or respiratory distress. Active airway intervention is rarely required but may be life saving if obstruction develops.

This study tested the ability of nicotine to alleviate the tobacco withdrawal syndrome. Signs and symptoms of tobacco withdrawal were measured in 100 smokers who fulfilled DSM-III criteria for tobacco dependence and a past history of tobacco withdrawal. After 2 evenings of baseline measurement, subjects were randomly assigned to receive either nicotine or placebo gum in a double blind manner. Subjects then stopped smoking, chewed gum freely, and returned on the 1st, 2nd, and 4th evenings of abstinence for further measurement. Nicotine reduced the increase in irritability, anxiety, difficulty concentrating, restlessness, impatience, and somatic complaints that subjects reported after cessation. Reductions in these withdrawal symptoms by nicotine were confirmed by ratings of significant others and by subjects' scores on the Profile of Mood States. Nicotine did not reduce the increases in cigarette craving, hunger, eating, insomnia, tremulousness , or supine heart rate after cessation. The effects of nicotine occurred immediately and persisted throughout the study. Although many subjects correctly identified their drug group, the efficacy of the gum was independent of subjects' identifications of drug. The relief of tobacco withdrawal by nicotine gum suggests that the tobacco withdrawal syndrome is caused, in part, by nicotine deprivation.

Comparison of three different shapes of behaviour in rats reveals following correlations: rats elaborating avoidance of closed space in response to cries of another individual (first group) significantly more frequently come into the centre of the "open field", exhibit greater alimentary activity in the new chamber in a state of moderate hunger and elaborate an alimentary reflex more readily as compared with the animals, which steadily prefer closed space (third group). But they elaborate inhibition of the motor alimentary reaction with difficulty. High stability of the elaborated behaviour (as expressed in the percentage of conditioned reactions after a three-week stressing effect) was exhibited by the animals of the first group, and non-stability by those of the third and second groups. The latter one, occupying a "middle" position was characterized by the highest level of motor restlessness in the avoidance situation, which is regarded as an analog of the alarm property.

Patients with neuromuscular disease may suffer from nocturnal respiratory failure despite normal daytime respiratory function. The physiological reduction in muscle tone during sleep may be life-threatening in a patient with impaired muscle strength. Nocturnal respiratory failure may occur in patients with the postpolio syndrome, amyotrophic lateral sclerosis, myasthenia gravis, myotonic dystrophy, and muscular dystrophy. Diagnosis of obstructive, central and mixed apneas, hypopneas, and hypoventilation is best made using polysomnography. Therapeutic options include noninvasive ventilation such as continuous positive airway pressure, bilevel positive airway pressure, intermittent positive pressure ventilation and, rarely, tracheostomy, oxygen, or protriptyline. Evaluation by a sleep specialist should be initiated in any neuromuscular patient with nocturnal symptoms such as air hunger, intermittent snoring or breathing, orthopnea, cyanosis, restlessness, and insomnia. Daytime symptoms may include morning drowsiness, headaches and excessive daytime sleepiness. Polycythemia, hypertension, and signs of heart failure may also be seen. Effective treatment is available, and may improve the quality of life, and possibly increase survival.
