Delirium Tremens     
The varied clinical manifestations and management of 14 male patients with delirium tremens (DT) have been studied. Eight patients were initially hospitalised for diseases unrelated to ethanol abuse i.e. 2 each for gun shot wound, myocardial infarction and stroke, and one each for pneumonia and gastroenteritis. One patient was going through withdrawal because of prodrome of viral hepatitis before he was hospitalised for uncontrolled agitation and delirium. Two known cases of mild essential hypertension on dietary therapy reported for agitation, abnormal behaviour, a single episode of tonic clonic seizure and hypertensive encephalopathy as they could not/did not get alcohol for 3 days. Three patients presented denovo with DT without concomitant illness. The other features besides delirium and hallucinations were tremulousness in 10, tachycardia in 12, fever in 3, diaphoresis in 2 and tonic clonic seizures in 4 patients. The symptoms fluctuated markedly at short intervals and 2 patients did not have any features of sympathetic overactivity. Altered hepatic biochemical parameters and ketonuria with normal blood sugar were noted in 4 and one patients respectively. Other biochemical parameters including serum electrolytes were normal. CT scan brain done for 5 patients revealed subdural haematoma in one. Cerebro spinal fluid (CSF) and EEG findings were noncontributory. All made good recovery with heavy doses of intravenous vitamin B complex, glucose and oral benzodiazepine. Short course of haloperidol was used in 2 patients. Two patients developed pancreatitis during follow up. All patients made complete recovery, and 8 patients have been followed for 8 to 12 months without relapse. The reason for hospitalisation in such cases is often unrelated to alcohol abuse; hence a detailed history of alcoholism is mandatory to identify those at risk as well as for prompt treatment and decreasing the mortality.Key Words: Alcohol withdrawal, Concomitant illnesses, Delirium, Precipitating events  相似文献

Background: Nocturnal reflux is important in the pathogenesis of esophagitis. The relationship between reflux and sleep is poorly understood, although data support both paradigms of nocturnal reflux causing arousal and nocturnal arousal allowing reflux. Furthermore, the effect of fundoplication on sleep is unknown. Methods: Seven volunteers and 11 patients with gastroesophageal reflux disease (GERD) and nocturnal symptoms were studied with esophageal pH and polysomnography at baseline and at 8 to 10 weeks follow-up evaluation, with patients undergoing interval fundoplication. Gastrointestinal and sleep questionnaires were completed before each study. Results: Questionnaire data between the groups showed differences at baseline, which were eliminated by surgery. No objective differences in sleep were observed between the groups at baseline or at follow-up evaluation. However, the patient group significantly increased the fraction of the night spent in deeper sleep (49.6% vs 58.3%; p = 0.022). Reflux events were associated with arousals in sleep. Conclusions: Fundoplication improves both subjective and objective sleep quality in patients with nocturnal GERD symptoms.  相似文献

The hormonal and metabolic response to the first feed of breast milk was studied in 12 infants at 4-6 hours of age. After the feed there was an increase in blood glucose concentration but no changes in the concentrations of lactate, pyruvate, alanine, or ketone bodies. The feed was followed by an increase in the concentrations of plasma insulin, growth hormone, gastrin, and enteroglucagon, but no change in levels of plasma glucagon or gastric inhibitory peptide. Several hormone systems are functionally active at birth and are stimulated by the first feed of milk.  相似文献
