Background: Eosinophilic cellulitis is a polymorphous, chronic disease characterized by eosinophil infiltration and granulomatous inflammation. Objective: Our purpose was to describe the clinical, histologic, and immunohistologic findings in three family members who have had eosinophilic cellulitis since childhood associated with mental retardation and abnormal body habitus. Methods: Family members were evaluated. Multiple skin biopsy specimens were obtained and examined after hematoxylin-and-eosin staining, by immunofluorescence and by electron microscopy. Blood specimens were analyzed by immunoassays for eosinophil granule proteins and eosinophil active cytokines. Results: Three short-statured, mentally retarded family members with abnormal body habitus in at least two generations had recurrent eosinophilic cellulitis. Peripheral blood and bone marrow eosinophilia was present. Plasma eosinophil granule major basic protein and eosinophil-derived neurotoxin levels were elevated with normal plasma eosinophil cationic protein levels. Eosinophil survival in culture was increased by patients’ plasma and was blocked with monoclonal interleukin-5 antibody. The level of plasma interleukin-5 was elevated. Lesional skin biopsy specimens showed massive staining for three eosinophil granule proteins. Electron microscopy showed eosinophil disruption. Conclusion: Eosinophilic cellulitis, mental retardation, and abnormal body habitus were likely inherited as a dominant syndrome in this family in which eosinophil involvement was striking.

There are no published comprehensive surveys of paediatric recovery room experience and the incidence of complications. A prospective survey was made of 16,700 consecutive admissions to the recovery room at the Royal Manchester Children's Hospital during the years 1985-1988. The incidence of respiratory complications was low, with laryngospasm 0.85%. The incidence of hypotension was higher than that in adult studies; over 50% of children recorded a decrease in blood pressure in the recovery room of more than 20%, compared to values before operation. The incidence of vomiting in the recovery room was also lower than in comparable adult studies. Certain aspects of recovery room practice changed during the 4 years of the study; these included routine oxygen administration, parents in the recovery room, and our approach to postoperative analgesia. The implications of these changes are discussed. 相似文献
Two techniques of total intravenous anaesthesia for laparoscopy were compared in 80 patients. Group 1 received alfentanil, propofol and vecuronium, and Group 2 alfentanil, midazolam, ketamine and vecuronium. Haemodynamic stability after induction and the pressor response to tracheal intubation were significantly different. There was no significant difference in recovery times between the two groups and little difference in other postoperative sequelae. 相似文献
The newly recognized class of 5-hydroxytryptamine receptors (5HT3) may be involved in the induction of nausea, since their pharmacological antagonists are effective against emesis induced by chemotherapy. 5HT3 receptors are present on enteric neurons, and 5HT3 blockers may produce mild constipation; we thus hypothesized that 5HT3 receptors would modulate colonic motility. To determine if GR 38032F, a selective 5HT3 antagonist known to have antiemetic effects, influences colonic transit in health, a randomized, double-blind, placebo-controlled crossover study was performed. Using a radiopaque marker technique, colonic transit was quantified in 39 healthy volunteers (19 men, 20 nonpregnant women) 18–70 years of age. On a standard 25-g fiber diet, 16 mg of GR 38032F was given orally thrice daily. Gastrointestinal peptides (peptide YY, human pancreatic polypeptide, neurotensin, motilin, gastrin-cholecystokinin, substance P) were also measured in plasma fasting and postprandially. Mean total colonic transit time on placebo was 27.8 hr, while on GR 38032F it was 39.1 hr (P<0.0005). Transit times through the left colon (P<0.0005) and rectosigmoid (P<0.05) were prolonged by the drug, but right colonic transit was not significantly altered. Transit times did not correlate with age or gender, but subjects with shorter transit times were significantly more affected than were those with longer transit times. The peak release of peptide YY was minimally decreased following GR 38032F (P<0.01), but the peak and integrated postprandial responses of human pancreatic polypeptide, neurotensin, motilin, gastrin-cholecystokinin, and substance P were not significantly altered by the drug. We conclude that 5HT3 receptors may be involved in the regulation of colonic transit in healthy man.Supported in part by a grant from Glaxo Group Research, Ltd., and the Mayo Digestive Disease Center (grant DK34988, National Institutes of Health, Bethesda, Maryland).Presented, in part, at the American Motility Socicty in October 1988, and published as an abstract inGastroenterology 95:891, 1988. 相似文献
Eleven patients with acquired prolongation of the Q-Tc interval and recurrent ventricular tachyarrhythmias were studied. Five patients required 5 to 44 direct current shocks to correct prolonged ventricular tachyarrhythmias, and five were given at least two antiarrhythmic agents in an attempt to control the arrhythmias. In 4 of the 11 patients, when thioridazine, diuretic drugs and antiarrhythmic agents were withdrawn and hypokalemia or hypocalcemia corrected, ventricular tachyarrhythmias did not recur. The Q-Tc interval normalized in 2 to 3 days. Ventricular tachyarrhythmias were recurrent in the remaining seven patients, despite withdrawal of the drugs that caused the Q-Tc prolongation, attempted correction of hypokalemia when present and the administration of antiarrhythmic agents to four of the seven. All antiarrhythmic agents were then withdrawn in this group.
Immediately on the establishment of overdrive ventricular or atrioventricular sequential pacing in these patients, ventricular tachyarrhythmias were abolished. No breakthrough ventricular tachyarrhythmias occurred during temporary pacing. Temporary pacing was required for an average of 10 days and the Q-Tc interval normalized an average of 5 days from the onset of pacing. Three patients required a permanent pacemaker, one because of chronic complete heart block, one because of the sick sinus syndrome, and one because of frequent ventricular ectopic complexes complicating ischemic heart disease. All 11 patients survived their period of hospitalization. 相似文献
Staff at public New York City sexually transmitted disease (STD) clinics screen patients for acute HIV infection (AHI) using pooled nucleic acid amplification tests. AHI screening is expensive but important for populations at high risk of acquiring HIV. We analyzed if targeting AHI screening in STD clinics could reduce program costs while maintaining AHI case detection.
Methods
From January 2009 through May 2010, we screened all patients with negative rapid HIV tests for AHI. Using risk information on cases detected during this universal screening period, we developed criteria for targeted AHI screening and compared case yields and testing costs during 12 months of universal screening (June 2009 through May 2010) vs. 12 months of targeted screening (June 2010 through May 2011).
Results
During the defined period of universal screening, we identified 40 AHI cases, and during targeted screening, we identified 35 AHI cases. Because of targeting efforts, the number needed to test to find one AHI case dropped from 1,631 to 254. With targeted screening, it cost an average of $4,535 per case detected and 39.3 cases were detected per 10,000 specimens; using universal screening, $29,088 was spent per case detected and 6.1 cases were detected per 10,000 specimens processed.
Conclusion
Targeted screening identified similar numbers of AHI cases as when screening all clinic patients seeking HIV testing, but at one-seventh the cost.During the acute phase of human immunodeficiency virus (HIV) infection (AHI), infected people are often unaware of their condition, as AHI symptoms—which include fever, sore throat, fatigue, myalgia, lymphadenopathy, rash, joint pain, night sweats, and diarrhea—are nonspecific.1 During AHI, patients are highly viremic (and, thus, highly infectious), and antibodies to HIV have not yet developed.2 This stage of infection, therefore, is not detected by traditional antibody tests. Detecting AHI requires nucleic acid amplification or antigen tests and enables infected people to adopt safer behaviors and be linked to earlier treatment and care, all of which may reduce HIV transmission.3,4 A multisite study conducted in 14 clinics in New York City (NYC); Los Angeles, California; and four counties in Florida from 2006 to 2008 found that AHI screening, when added to point-of-care rapid testing, increased HIV detection by 8.2% across all sites; in three NYC clinics, 24% more HIV infections were detected using AHI screening than with HIV detection using rapid antibody tests alone (seven cases detected by nucleic acid amplification testing [NAAT]; 22 cases detected by rapid test).5 NAAT is an important tool for identifying AHI, and NAAT pooling methods (pNAATs) help to contain the costs of screening.6 By 2009, the NYC Department of Health and Mental Hygiene (NYC DOHMH) had implemented routine AHI screening via pNAAT for all patients with negative rapid HIV tests in all of its sexually transmitted disease (STD) clinics. At that time, the NYC DOHMH joined just a handful of state and local health departments in the United States that were routinely using pNAAT.7While AHI screening increased HIV detection in NYC STD clinics, it came at a considerable cost. Annualized other-than-personnel costs of this screening were more than $1 million, or approximately $30,000 per new diagnosis, which was as much as 16 times greater than the average cost of routine opt-out HIV screening in health-care facilities in the U.S.8 We present our evaluation of a strategy to reduce program costs while maintaining a high level of AHI case detection among clinic patients. 相似文献
