We compared the functional status of the hypothalamic dopaminergic tone in patients given an allogeneic hematopoietic stem cell transplantation (allo-HSCT) with chronic graft-versus-host disease (GVHD) with that observed in patients with allo-HSCT without chronic GVHD and in healthy controls. The effect of acute dopaminergic blockade with intravenous metoclopramide on serum prolactin (PRL) concentrations was evaluated. Twenty volunteers, 20 to 52 years of age, seronegative for both hepatitis C virus and the human immunodeficiency virus, were studied: (1) 10 clinically healthy men (group 1), and (2) 9 patients with leukemia, and 1 patient with refractory aplastic anemia who underwent allo-HSCT, 5 of whom (3 men and 2 women) developed chronic GVHD (group 2), and 5 (3 men and 2 women) who did not develop chronic GVHD (group 3). Serum PRL concentrations were measured both fasting and after intravenous administration of metoclopramide (10-mg bolus). The area under the PRL curve was calculated. Patients in group 2 were older than those in groups 1 and 3 (P<.018), but their body mass index was similar. Fasting serum PRL concentrations were similar among the 3 groups; however, group 2 had higher PRL concentrations throughout the test (P<.001) and a greater area under the PRL curve than groups 1 and 3 (P<.001), without differences between the last 2 groups. The differences remained significant after adjustment for age (P<.01). Our results in a small group of patients with chronic GVHD after allo-HSCT suggest the existence of an increased functional level of their hypothalamic dopamine tone, which would favor a tendency toward a diminished endogenous production, release of pituitary PRL, or both. This could represent an adaptive mechanism aiming to maintain circulating PRL concentrations within a physiological range. 相似文献

Hybrid tumours of the salivary glands. A report of two cases involving the palate and a review of the literature 总被引:1,自引:0,他引:1
Luz María Ruíz-Godoy R Adalberto Mosqueda-Taylor Lourdes Suárez-Roa Adela Poitevin Esther Bandala-Sánchez Abelardo Meneses-García 《European archives of oto-rhino-laryngology》2003,260(6):312-315
Hybrid tumours are very rare salivary gland lesions composed of two or more different tumoural entities in a single neoplasm that arise within a definite topographical region. In most cases adenoid cystic carcinoma has been the predominant component in these lesions. In this study we describe two patients with hybrid tumours located in the palate, one in a 49-year-old woman and one in a 71-year-old man. The first case involved adenoid cystic carcinoma and mucoepidermoid carcinoma, and the patient in the second case exhibited adenoid cystic carcinoma and epithelial-myoepithelial carcinoma. Both patients were treated with surgery and radiotherapy, and there has been no evidence of recurrence after 13 and 36 months of follow-up, respectively. The recognition of the histologic component with the higher grade of malignancy in every case of hybrid tumour of the salivary glands is a necessary step to determine the biological behaviour and, consequently, to determine the proper therapeutic approach. 相似文献

OBJECTIVE: This study analyzes the differences in psychological variables and symptomatology between temporomandibular disorder diagnosis subgroups. STUDY DESIGN: The sample included 114 temporomandibular disorder patients that were evaluated in coping, distress, and temporomandibular characteristics. Diagnostic muscular (n = 58) and articular (n = 56) subgroups were compared in these variables through a MANCOVA. RESULTS: Muscular patients show a higher level of general distress, specifically in the anxiety and somatization subscales and a more active coping style, with a tendency of a minor use of humor and a higher number of parafunctional habits, specifically, biting nails, hangnails, and lips. CONCLUSION: We discuss the differences found in order to design the targets of the psychological intervention of temporomandibular patients. 相似文献

We compared three different microsurgical vasovasostomy techniques on the rat vas deferens using absorbable and non-absorbable sutures and a fibrin adhesive technique. The best method was an extramucosal technique over a splint using vicryl. The worst results were seen using adhesive. 相似文献

Reductions in depressed mood and denial coping during cognitive behavioral stress management with hiv-positive gay men treated with haart 总被引:1,自引:1,他引:0
Adam W. Carrico M.S. Michael H. Antoni Ph.D. Ron E. Durán Ph.D. Gail Ironson M.D. Ph.D. Frank Penedo Ph.D. Mary Ann Fletcher Ph.D. Nancy Klimas M.D. Neil Schneiderman Ph.D. 《Annals of behavioral medicine》2006,31(2):155-164
Background: Stress management interventions for HIV-positive persons have been designed to enhance coping skills and encourage health-promoting
behaviors with the hope of decreasing distress and slowing disease progression.Purpose: We examined the efficacy of a cognitive behavioral stress management (CBSM) intervention in combination with medication
adherence training (MAT) in 130 gay and bisexual men living with HIV infection.Methods: Participants were randomized to either a 10-week CBSM+MAT intervention (n = 76) or a MAT-only condition (n = 54). Measures
of self-reported adherence, active cognitive coping (i.e., acceptance and positive reinterpretation), avoidant coping (i.e.,
denial and behavioral disengagement), and depressed mood were examined over the 10-week intervention period.Results: Men in CBSM+MAT reported reductions in depressed mood and denial coping during the 10-week intervention period, but no changes
in active cognitive coping or self-reported adherence were observed. Using path analysis, greater reliance on denial coping
at baseline was associated with decreased depressed mood at 10 weeks. We also determined that CBSM+MAT may decrease depressed
mood by reducing reliance on denial coping over the 10-week intervention period.Conclusions: Although denial may be an effective means of distress reduction in the short term, reliance on this coping strategy may
result in a decreased capacity to effectively manage a variety of disease-related stressors in the long term. CBSM+MAT addresses
this potentially detrimental pattern by teaching stress reduction skills that may decrease depressed mood via reduced reliance
on denial coping.

Blood flow pattern recording of hepatic veins using pulsed Doppler technique is a valid method for the assessment of hemodynamic changes in right atrium. We describe a patient with severe aortic regurgitation secondary to acute infective endocarditis who underwent surgical repair. Before surgery and during the postoperative period, several evolutive studies (including conventional echo and hepatic veins pulsed Doppler recordings) were performed. The different central blood flow patterns were correlated with changing hemodynamic conditions during follow-up of the patient. These central flow velocities reflect changes in right atrial pressure contours, and are easily obtained non-invasively with pulsed wave Doppler ultrasound of the hepatic veins. They could be an useful method for assessing right heart filling dynamics, reporting characteristic patterns in other cardiac disease states. 相似文献

Objectives:
To examine the extent to which school climate and school pressure could predict other aspects of adolescents’ lives, most particularly their emotional health and bullying. Furthermore, the study sought to investigate if these relationships were consistent across countries. 相似文献10.

The following case involved duplication of the right atrioventricular valve in a patient with a common atrium. The accessory orifice, formed by two fine leaflets, connected the right atrium with the right ventricular outflow tract and had no subvalvular apparatus. Successful surgical correction was accomplished under standard cardiopulmonary bypass. 相似文献
