We have studied 25 thymomas by both immunohistochemistry and in situ hybridization for the presence of growth hormone (GH)-producing cells. Our results indicate that 1) GH-immunoreactive cells were present in 13 of 17 thymomas of cortical and predominantly cortical type but not in medullary (spindled) thymomas (n = 3) or low- to high-grade thymic carcinomas (n = 5), 2) GH-positive cells were mainly located at the periphery of the neoplastic lobules, at the periphery of the perivascular spaces and in the areas of medullary differentiation, 3) cells containing GH mRNA appeared at locations similar to those of GH-immunoreactive cells, and 4) GH-immunoreactive material was present only in the epithelial cell component as revealed by immunoelectron microscopy. In conclusion, this paper demonstrates the occurrence of GH-producing cells in noncarcinoid thymic tumors. The relevance of GH in thymoma cell biology requires additional investigations. 相似文献

The role of adrenergic mechanism in the pathogenesis of allergic disease is controversial. Recent experimental and clinical reports have suggested that -adrenergic blockade impairs and stimulation enhances extrarenal potassium uptake in humans. This led us to study the effect of the intravenous administration of salbutamol, a specific -2-adrenergic agonist, on serum potassium in 9 healthy subjects and in 23 patients with allergic asthma and/or rhinitis. Serum potassium fell significantly and reached a peak decline at the end of venous infusion in all the normal subjects. Seventeen atopic subjects showed a lower or absent serum K+ decrement: there was no difference between asthmatic and rhinitic patients. There was no relation among the salbutamol-induced serum potassium decrement, serum glucose increment, blood pressure and heart-rate changes, and nonspecific bronchial reactivity. These findings suggest that -2-adrenergic hyporesponsiveness is present only in some allergic patients. 相似文献

One hundred and fifty-two children affected by respiratory syndromes, probably due to allergy, underwent skin testing to a range of extracts including several different species of mites. The incidence of positive reactions to different allergens was studied in two groups: below and over 4 years, each including both outpatients and inpatients. The aetiologic role of mites has been evaluated considering positive skin tests to single species between and within families. 相似文献

Endometriosis is a disease in continuous evolution due to its various aspects and atypical localizations. Every year many women all over the world are affected by it. In typical localizations the diagnosis is simple; the symptoms include pelvic pain and in most of cases sterility. In rare localizations the symptoms are non-specific and the diagnosis is difficult. In particular an intestinal isolated localization is often asymptomatic or can cause non-specific pelvic pain, irregular intestinal activity and in such case, a subocclusive condition often with a diagnosis of inflammatory bowel disease. Two cases of rare localizations of endometriosis are described in the intestinal wall and a cesarean section scar. An analysis of the etiopathogenesis and diagnostic approach in these rare localizations is presented. 相似文献

A case of hyperkeratosis follicularis et parafollicularis in cutem penetrans Kyrle's disease in a 41-year-old woman is described. It was a recurrence of a lesion surgically removed and originally diagnosed as invasive squamous cell carcinoma. Kyrle's disease is a rare dermatosis and should not be confused with neoplastic conditions i.e. squamous cell carcinoma. Pathologists should be aware of such conditions in order to avoid misdiagnosis, which can imply over treatment for the patient. 相似文献

Two cases of bronchial stenosis secondary to inflammatory processes with the clinical picture of chronic respiratory disease resistant to medical treatment were treated successfully by selective balloon dilatation. This is an alternative to lobectomy and other conservative methods presently in use. We used an angioplasty balloon dilator catheter for the dilatations; the method is described and the advantages and disadvantages are discussed. 相似文献
