The effects on the oesophagus of an aromatic oil, guaiacol, has been examined in a group of 20 patients with reflux oesophagitis and also normal volunteers. This agent produced a rapid and sustained rise in resting lower oesophageal sphincter pressures and the peristaltic pressures induced in response to swallowing liquids. This compound may prove useful in the treatment of patients with reflux oesophagitis and other disorders of oesophageal motility.  相似文献

Allescheria boydii, a true fungus frequently isolated from soil, is best known as a causative agent of maduromycosis of the foot. In our report we describe two patients under treatment for acute leukemia who died from rapidly progressive A. boydii infections. One patient had signs of central nervous system infection and was found at autopsy to have had a large brain abscess. The second patient had a cavitary necrotizing pneumonia with thoracic inlet obstruction (Pancoast's syndrome) and failed to show improvement despite treatment with amphotericin B. The clinical spectrum of allescheriasis is reviewed with particular emphasis on its role as a pathogen in the compromised host. Since A. boydii may resemble other fungi morphologically in tissue sections and may produce infections clinically similar to other mycoses, culture of the organism is required for definitive diagnosis. Based on recently reported in vitro susceptibility studies, miconazole may have a future role in the therapy of A. boydii infections which are resistant to presently available antifungal agents.  相似文献

Mortality data for ulcerative colitis, Crohn's disease, and unspecified inflammatory bowel disease were examined for the countries Venezuela, Italy, and France during the decade 1969-1978. These figures were compared with similar data from England and Wales obtained from 1965 to 1975. In Italy and France deaths from Crohn's disease and ulcerative colitis were low and showed little change during the period of observation. Figures for inflammatory bowel disease from Venezuela were high and appeared to show a marked fall which may simply reflect a change in diagnostic criteria.  相似文献

OBJECTIVE: To evaluate the safety and efficacy of a new low profile balloon septostomy catheter in neonatal animals as well as in one newborn infant. BACKGROUND: Balloon atrial septostomy remains one of the most commonly performed palliative procedures in pediatric cardiology. The currently available septostomy catheter requires a large introducer sheath (6 or 7F), does not have an end hole for confirmation of position or pressure measurement and is limited in patients with a small left atrium due to its large balloon inflated diameter. METHODS: Four neonatal piglets (average weight 3.9 kg) underwent percutaneous balloon atrial septostomy using the new balloon catheter inflated to 1 cc via a 5F sheath in the femoral vein. Two other piglets (average weight 4.9 kg) underwent septostomy with the conventional catheter inflated to 3.5 cc via a 6 or 7F sheath in the femoral vein. All animals underwent transthoracic echocardiography pre and post septostomy. All animals were sacrificed after the procedure and the size of the atrial defect created was measured. One neonate with Taussig-Bing anomaly underwent septostomy with the new balloon catheter. RESULTS: The left atrium was entered in all piglets. It was easier to enter the left atrium with an end hole catheter which was exchanged over a wire with the septostomy catheter. Septostomy was performed with the new or conventional catheters without complications. Echocardiography demonstrated a very small patent foramen ovale prior to the procedure and a large atrial defect after septostomy. The average size of the defect created by the new catheter was 11.3 x 10 mm in diameter and 11 x 10 mm using the conventional catheter. A 10 x 10 mm atrial communication was created in the neonate. CONCLUSIONS: This study demonstrates the safety and efficacy of this new catheter. This catheter will be of potential importance in patients with a small left atrium and in small neonates with congenital heart disease requiring septostomy.  相似文献

Purpose

Sexual minority adults experience fivefold greater risk of suicide attempt, as compared with heterosexuals. Establishing age-specific epidemiological patterns of suicide is a prerequisite to planning interventions to redress the sexual orientation suicide inequity, and such patterns must be carefully interpreted in light of correlated period and cohort effects. We, therefore, combined US and Canadian data (1985–2017) from primary (two pooled multi-year national surveys, N = 15,477 and N = 126,463) and secondary (published, meta-analytic, N = 122,966) sources to separately estimate age, period, and cohort trends in self-reported suicide attempts among sexual minorities.

Methods

Age- and gender-stratified cross-sectional data were used to infer age and cohort effects. Age-collapsed meta-analyzed data were used to infer period effects among sexual minorities of all genders.

Results

We identified a bimodal age distribution in recent suicide attempts for sexual minorities across genders, though more pronounced among sexual minority men: one peak in adolescence (18–20 years of age for both genders) and one peak nearing mid-life (30–35 years of age for men; 35–40 years of age for women). This pattern was also apparent using recall data within birth cohorts of sexual minority men, suggesting it is not an artifact of birth cohort effects. Finally, we observed decreasing trends in lifetime suicide attempt prevalence estimates for both sexual minorities and heterosexuals, though these decreases did not affect the magnitude of the sexual orientation disparity.

Conclusion

In the context of exclusively adolescent-focused suicide prevention interventions for sexual minorities, tailored suicide prevention for sexual minority adults should be pursued throughout the life course.
