In the dose range of 4.0--32.0 mg/kg s.c., caffeine produced most of the signs which are commonly seen after the administration of naloxone (0.05 mg/kg s.c.) to morphine-dependent monkeys. The signs designated as lying on side or abdomen, avoiding contact, vocalizing, crawling or rolling, restlessness or pacing, tremors, retching, vomiting, coughing, vocalizing when abdomen palpated, rigid abdomen and salivation were noted. A randomized and blind experimental design, which included vehicle and positive (naloxone) controls was used. The significance of the differences between total scores for the whole syndrome was tested by the Mann-Whitney U-test. In preliminary studies in naive monkeys, caffeine was found to elicit some withdrawal signs but the results were equivocal. Na benzoate also elicited some withdrawal signs in morphine-dependent monkeys at 32.0 mg/kg s.c., but few signs were seen in naive monkeys. Caffeine was found to be approximately 10X more active than Na benzoate in inhibiting cAMP phosphodiesterase activity in a neuroblastoma cell whole homogenate assay. These results are consistent with the observations of Collier and Francis that morphine abstinence in rodents is associated with increased brain levels of cAMP.

Thirty patients, scheduled for short urological surgical procedures and ranked ASA 1 or 2, were randomly assigned to two homogenous groups. In group P, they were given a 2 mg.kg-1 bolus of propofol and 10 micrograms.kg-1 of alfentanil, followed by a continuous infusion of propofol (5 mg.kg-1.h-1) and 5 micrograms.kg-1 doses of alfentanil. In group E, they were given a 0.3 mg.kg-1 bolus of etomidate, followed by an infusion (1.5 mg.kg-1.h-1). The doses of alfentanil were the same as in group P. Further doses of either propofol (0.5 mg.kg-1) or etomidate (0.2 mg.kg-1) were used should anaesthesia prove not to be deep enough. The patients were not intubated, and breathed spontaneously. Surgery lasted a mean of 18.3 +/- 11.8 min (group P) and 18.8 +/- 9.4 min (group E). The following parameters were studied: the amount of each agent required for maintenance of anaesthesia, the duration of apnoea at induction, the quality of anaesthesia and of muscle relaxation, adverse effects (coughing, trismus, restlessness, nausea, vomiting), the time required for recovery, and its quality. In group P, there was a 27% decrease in arterial pressure, without any tachycardia or hypoxia, together with a quick recovery of excellent quality. On the other hand, in group E, there was little or no haemodynamic alteration, but there often was a trismus at induction. Hypoxia also occurred during induction with etomidate, being severe enough in one case to require tracheal intubation and artificial ventilation. The reasons for this hypoxia seemed to be the apnoea and the trismus, which tends to hinder assisted ventilation.(ABSTRACT TRUNCATED AT 250 WORDS)

This study documents 3-year retrospective analysis of accidental kerosene oil poisoning in 70 children with regard to clinical profile, radiological changes and outcome. About 77% of cases were between 1 and 3 years old. Fifty children (71.4%) developed significant symptoms, with onset soon after to within 10 hours of ingestion. These included breathlessness (55.7%), fever (47.1%), cough (31.4%), restlessness (25.7%) and abdominal distension (15.7%). Chest X-rays were obtained in 65 children. Abnormal radiographs were seen in 45 (69.2%) children with right basal infiltrates being the commonest picture (21.4%). Ingestion of more than one ounce of kerosene oil adversely affected the clinical and radiological profile. Severely malnourished children had extensive radiological changes and poorer clinical outcome. One case developed myocarditis, a complication which has not been reported to the best of our knowledge. Mortality rate was 4.3%. All deaths occurred within 48 hours of admission.

Promethazine, available by prescription only since its introduction in 1946, has been widely used for pediatric patients because of its antihistaminic, antiemetic, and sedative properties. Recently, it's makers have sought Federal Drug Administration approval to introduce two liquid over the counter allergy/cold/cough products containing promethazine as an active ingredient. Although millions of doses have been administered, promethazine use has not been free of risk. Promethazine has been reported to cause significant sedation, agitation, hallucinations, seizures, dystonic reactions, and possibly apparent life-threatening events or sudden infant death syndrome. The impact of these relatively uncommon adverse reactions on children would be minimal if parents would use over the counter promethazine only for appropriate indications and only in children greater than 2 years of age. However, according to results of research evaluating the use of various over the counter medications by families for their children, promethazine will be used inappropriately. Both its over the counter status, implying a certain margin of safety, and its formulation as a syrup, providing ease of administration, should increase its use in all age groups including that by children less than 2 years of age who may be most vulnerable to the adverse reactions associated with the drug's use.

924 subjects, 542 males and 382 females working in grainstoring, or herb-storing, from different parts of Anhui Province were examined for the possible existence of pulmonary acariasis. 49 cases(5.3%), 31 males and 18 females, were found positive for mites in their sputum. 83.7% of the sufferers aged 16-45. 22 out of the 22 out of the 49 sufferers developed a marked eosinophilia ranging from 4% to 48% and a count of 320-5,050/mm3, whereas X-ray films revealed varied degrees of widening lung hilum shadow with increased and disordered lung markings. In some cases, the chest-film showed a lot of scattered nodular shadows 1-5 mm in diameter in the lung lobes. The symptoms presented were cough, expectoration, depression in the chest, restlessness, low fever, asthma, hemoptysis, etc. 10 species of mites were found in the sputum of the 49 sufferers, i.e. Acarus siro, Tyrophagus putreseltiae, Aleuroglyphus ovatus, Caloglyphus berlesei, C. myoophagus, Dermatophagoides farinae, D. pteronyssinus, Euroglyphus maynei, Tarsonemus granarius, Cheyletus eruditus.

A case of double aortic arch is reported. The male patient, 11-month-old, had breathed with a constant stridor since his birth and had frequent attacks of respiratory tract infection and dyspnea. The child was admitted because of restlessness, fever, stridor and cough. Dyspnea with cyanosis appeared later, and required intubation and mechanical ventilation. After then, three attempts to extubate the infant were made, but failed. A double aortic arch was suspected by bronchogram, esophagogram, and confirmed by cardiac catheterization. Through a left thoracotomy, the smaller left arch and the ligmentem arteriosum were divided to relieve the obstruction of trachea from the compression of the vascular ring. Postoperative convalescence was normal. Symptoms of double aortic arch vary with the degree of obstruction of the trachea and esophagus, ranging from mild to life-threatening respiratory obstruction and apnea. Inspiratory stridor, dyspnea, and wheezing, which are accentuated with feeding, crying, or respiratory infections, are characteristic clinical findings. The diagnosis is established by aid of an esophagography. Left thoracotomy, with division of the smaller aortic arch, is the only satisfactory treatment.

We studied the effects of positional treatment and cisapride (a new prokinetic agent) on the incidence and duration of gastroesophageal reflux in 22 infants (4-26 weeks old) in asleep, awake, fasted, and postcibal periods. In addition to gastroesophageal reflux (assessed by 24-h continuous esophageal pH monitoring), all infants presented with a disrupted irregular sleep pattern ("respiratory dysfunction") (assessed by a simultaneously performed cardiopneumogram). Reflux was particularly prominent during the sleep and fasted periods. Investigations (cardiopneumogram and esophageal pH monitoring) in the study population were repeated under treatment conditions (cisapride) after 13-16 days. All pH monitoring data with regard to the total investigation time decreased significantly (p less than 0.001). The treatment-related differences were largest in the asleep and fasted periods, but treatment data were not completely within normal ranges (established in age-matched asymptomatic infants), as they were for the awake periods. Associated symptoms of gastroesophageal reflux (belching, cough, nocturnal wheezing, irritability, and restlessness at night) were evaluated before and during treatment by history. A combination of positional treatment and cisapride seemed effective (objectivated by pH monitoring data and clinical improvement); cisapride did not cause adverse reactions. The disrupted sleep pattern improved significantly or disappeared (p less than 0.001) in all infants. These data suggest that in a number of young infants, gastroesophageal reflux may be associated with a disturbed, irregular sleep of poor quality, which is characterized by a typical breathing pattern (multiple, irregularly repeated, short apneas).

To identify which clinical findings serve to differentiate acute epiglottitis from laryngotracheitis and also to evaluate the role of direct inspection of the epiglottis in the evaluation of children initially thought to have laryngotracheitis, we prospectively evaluated 155 children presenting to the emergency room with acute stridor. Three of the findings on physical examination were associated with epiglottitis: absence of spontaneous cough, drooling, and agitation. The diagnosis assigned prior to inspection of the epiglottis was incorrect in two of six patients with epiglottitis and in three of 149 patients with laryngotracheitis. The diagnosis made after inspection was correct in all 155 patients. Minor complications of inspection were seen in seven patients with laryngotracheitis. No complications were seen in the children with epiglottitis. We conclude that drooling, agitation, and absence of cough are predictors of epiglottitis, but clinical findings alone cannot exclude epiglottitis in every child who appears to have laryngotracheitis. When laryngotracheitis is the suspected diagnosis, inspection of the epiglottis by a pediatrician in a hospital emergency room is an effective aid to the evaluation of the child with acute stridor.

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.

Etomidate has been studied in two groups of patients. In Group 1, 50 patients received etomidate 100 micrograms/kg/minute with fentanyl and a muscle relaxant, ventilation being with air and oxygen (50%). The technique gave a smooth, pleasant induction with all patients asleep within 2 minutes. The incidence of pain on infusion was 6% and of myoclonus 6%. Cardiovascular changes were minimal, the most common finding being persistent tachycardia. The mean recovery time was 9.1 minutes. There was no incidence of awareness, recall, or thrombophlebitis, but a 20% incidence of nausea and vomiting. In Group 2, 20 patients received the same dosage of etomidate to supplement spinal anaesthesia for lower abdominal surgery. The technique worked most satisfactorily, with patients falling quietly to sleep within 2-3 minutes with no hiccoughs, coughing or laryngospasm. Six patients exhibited myoclonus, one being severe. In no case did myoclonus interfere with the operation. The cardiovascular system remained stable in all patients. Mean recovery time was 16.1 minutes (range 3-38 minutes). Twitching and restlessness were the main complications during recovery.
