Migraine in health workers: working in a hospital can be considered an advantage?

Migraine is the most common form of headache, and is one of the most diffused pathologies in the world. Moreover, patients often lose years before obtaining a correct diagnosis. The aim of this study was to evaluate whether diagnostic delay differs between hospital workers, in theory more sensible to health problems, and common people. We compared our cohort of patients attending the headache center on which we put a diagnosis of migraine with and without aura with a sample of hospital workers investigated about headache presence and characteristics. Particularly, hospital workers were evaluated by ID-migraine test, a three-question test validated to formulate a migraine diagnosis. Continuous variables (age and diagnostic delay) were compared with t test for independent samples. Dichotomous and categorical variables were compared with Chi squared test. The mean difference between in-hospital workers and outpatients was analyzed with a GLM/multivariate model accounting for age and sex. The difference between the single subcategory of workers affected by migraine was explored with a GLM/multivariate model accounting of age and sex. Five hundred and ninety-nine patients affected by migraine with and without aura were enrolled. Demographical characteristics were comparable in the two study populations. In-hospital workers (99 patients) had a mean longer diagnostic delay (14.89 years; 95 % CI: 7.85-21.93 years) with respect to the outpatients (12.13 years; 95 % CI: 5.37-18.89 years). The difference resulted statistically significant at the multivariate model (p < 0.05). Single subpopulations of in-hospital workers did not have a statistically significant different delay in diagnosing migraine. Diagnostic delay was significantly longer in hospital workers with respect to outpatients. Then, we can conclude that our population of hospital workers did not present a particular attention to their headache, probably because of a tendency to self-treating. Moreover, we did not find differences among different typology of workers, underlining that different job experience and education did not contribute to a best management of headache. More information and informative initiatives are necessary to sensitize people about migraine, especially among hospital workers.

Cultured human gallbladder epithelia. Methods and partial characterization of a carcinoma-derived model.

BACKGROUND: Gallstone disease remains a leading cause of morbidity and mortality in humans. Despite extensive research into the physiology of the gallbladder, little is known about mucosal events that precede and contribute to stone formation. Here, we describe and partially characterize a cultured epithelial model of human gallbladder mucosa. EXPERIMENTAL DESIGN: Cells originally obtained from a well-differentiated gallbladder mucosal carcinoma were cultured in modified Eagle's minimum media (supplemented with fetal calf serum and antibiotics) on polycarbonate supporting matrices. RESULTS: Cell cultures were observed to come to confluence with 6 to 9 days. Light and transmission electron microscopy demonstrated the resultant epithelia to be predominantly one cell thick, to be polar in orientation, and to have apical villi. Epithelia exhibited cytokeratin markers consistent with their epithelia origin, functionally acidified the mucosal bathing solutions, and secreted mucin. Further experiments demonstrated transepithelial potential differences, mucosal-to-serosal transfer of sodium which could be inhibited with amiloride and 4-acetamido-4'-isothiocyanatostilbene-2-2'-disulfonic acid, and paracellular movement of neutral molecular probes inversely related to size. CONCLUSIONS: This culture model of human gallbladder mucosal carcinoma cells exhibits parameters consistent with native gallbladder and may offer a convenient new research tool for the study of the pathophysiology of gallstone formation.

Faecal elimination of steroids in rats after oral administration of mepartricin.

Treatment of both male and female rats with 5 IU/day mepartricin for 7-10 days administered by gastric tubing resulted in an increased faecal excretion of some steroids. Mean rate of elimination of total oestrogens was enhanced by 45% in male rats and by 14% in female rats, and the average excretion of conjugated oestrogen was also increased in the female animals. Faecal elimination of cholesterol was 37% and 42% higher in male and female rats, respectively, after mepartricin treatment, and in male rats plasma concentrations of cholesterol were reduced following treatment. It is suggested mepartricin acts either by changing the intestinal flora or by acting directly on the steroid moieties, and it is speculated that a similar mechanism may occur in man.

Changes in the plasma pattern of sex steroids in patients with liver cirrhosis treated with mepartricin.

Mepartricin was given to cirrhotic patients in order to evaluate its effect on the imbalance of sex steroids which is typical of this disorder. Patients were divided into two group: one group received placebo (n = 19) and the other received 150,000 IU/day mepartricin for 30 days (n = 19). The patients were evaluated by separate medical staff who were unaware of the treatment. Mepartricin significantly decreased the plasma concentration of testosterone, oestradiol and prolactin as compared with the values at the start of the trial, while no significant changes were seen in the occurrence of gynaecomastia. No relevant changes were seen in patients receiving the control, except for a slight increase in the peripheral concentration of androstenedione, aldosterone and follicle stimulating hormone.

Lymphocyte function tests in cirrhotic patients under treatment with spironolactone and potassium canrenoate.

This controlled study in cirrhotic patients investigated whether two antialdosteronic steroids, spironolactone (100-200 mg/day; n = 12 patient pairs) and potassium canrenoate (50-100 mg/day, n = 32 patient pairs) which are reported to bind to intracellular membranes and modify cytochrome P-450, could also produce nuclear changes. The model used was the response of peripheral lymphocytes to blastogenic agents by studying lymphocyte sub-populations. No changes occurred in the B- and T-lymphocyte sub-populations or in the helper and suppressor sub-types. The response to the blastogenic agents, phytohaemagglutinin and purified protein derived from mycobacteria, did not change significantly from before entry into the study to the follow-up (18.1 +/- 2.9 months). All control patients (n = 44 patient pairs) had slightly greater mitogenic activity compared with patients treated with spironolactone; no difference was found when control patients were compared with patients given potassium canrenoate. The difference between spironolactone and potassium canrenoate might be due to toxicity caused by the thio group of spironolactone. Overall, however, both drugs may be regarded as safe, in terms of effects on lymphatic tissue, occurring during the course of cirrhosis.
