Nineteen female adolescent inpatients diagnosed with anorexia nervosa, restricting type (AN-R) and 16 non-eating disordered (ED) controls were assessed for plasma dehydroepiandrosterone (DHEA), dehydroepiandrosterone-sulphate (DHEA-S), and cortisol levels, and for eating-related and non-eating-related psychopathology. AN-R patients were assessed at admission, 1 month and 4 months following hospitalization. The non-ED controls were assessed once. No baseline between-group differences were found in plasma cortisol, DHEA, and DHEA-S levels, whereas the patient group had a significantly lower Cortisol/DHEA-S ratio and elevated scores on most psychopathological parameters. A significant increase was found in the body mass index of the AN-R patients at 4 months post-hospitalization, accompanied by a decrease in plasma cortisol levels and a trend towards decreased Cortisol/DHEA and Cortisol/DHEA-S ratios, whereas no change occurred in psychopathology. The difference in Cortisol/DHEA-S ratio between AN-R patients and non-ED controls, and the different patterns of change in cortisol vs. DHEA(-S) levels following weight restoration, may in part account for the feeding difficulties in AN, particularly during refeeding. 相似文献

Post-traumatic stress disorder (PTSD) affects about 20-30% of exposed individuals. Clinical studies of PTSD generally employ stringent criteria for inclusion in study populations, and yet in animal studies the data collection and analysis are generally expressed as a function of exposed vs nonexposed populations, regardless of individual variation in response. Prior data support an approach to animal models analogous to inclusion criteria in clinical studies. This series of studies sought to assess prevalence rates of maladaptive vs adaptive responses determined according to a more stringent approach to the concept of inclusion/exclusion criteria (cutoff behavioral criteria-CBC), consisting of two successive behavioral tests (elevated plus maze and acoustic startle response tests). The rats were exposed to stressors in two different paradigms; exposure to a predator and underwater trauma. The prevalence rates of maladaptive responses to stress in these two distinct models dropped over time from 90% in the acute phase to 25% enduring/maladaptive response at 7 days, to remain constant over 30 days. As setting the affected individuals apart from the unaffected approximates clinical studies, it might also help to clarify some of the pending issues in PTSD research. 相似文献

Between 1976 and 1983, 28 patients with Kaposi's sarcoma were treated in the Department of Radiation and Clinical Oncology of the Hadassah University Hospital in Jerusalem. Most of the patients (16, i.e. 57%) were Jews of European origin. Eighteen (64.2%) of the patients presented with severe leg edema in addition to multifocal, disseminated skin lesions. Only one patient was free of clinical disease in the lower extremities. Large, ulcerated masses were seen in three patients. The affected limbs were immersed in a water bath and irradiated with two-opposing portals to a total dose of 3000 rads. Total disappearance of the skin lesions was achieved in 89% of the patients, although the limb edema regressed completely in only 56% of the patients. 相似文献

Résumé Indem wir unter Fortlassung aller histologischen Details zusammenfassen, was für die Krebsforschung im allgemeinen von Interesse zu sein scheint, so können wir als Hauptergebnis ansehen, dass bei der Ueberimpfung der Mäusekrebse der Impftumor durch mitotische Teilungen aus dem überlebenden Zellmaterial des transplantierten Tumorstückchens hervorgeht. 相似文献

EBV-positive mucocutaneous ulcer (EBV-MCU) was classified as a rare new entity of the lymphoproliferative B-cell diseases by the WHO in 2017 and must be distinguished from head and neck squamous cell carcinoma by early biopsy. The aim of the study is to raise awareness of the disease and to give a review of the current literature and a recommendation for EBV-MCU management. All EBV-MCU cases of the head and neck region published so far were included. We also report a case of a pharyngeal EBV-MCU in an 89-year-old patient who was immunosuppressed by chronic lymphatic leukaemia/small lymphocytic lymphoma (CLL/SLL). In contrast to all previously described cases, histopathology showed a co-infiltration of EBV-MCU and CLL/SLL. A total of 181 cases were identified on PubMed and summarised. EBV-MCU was predominantly caused by immunosuppressive drug therapy. Complete remission could be achieved in 68% of cases and was mainly attributed to a reduction of the immunosuppressive therapy alone (72%). However, some severe cases require more aggressive treatment. Regarding the various histopathologic similarities to other lymphoproliferative disorders, the diagnosis of EBV-MCU can be misleading, with a great impact on patient care and treatment. This diagnosis must be made with caution and requires a combination of clinical, morphological and immunophenotypic features. 相似文献

BACKGROUND: Jewish culturally supported beliefs may discourage drinking and drunkenness as ways of socialising and coping with stress. Thus Jewish men under stress may be relatively more likely to become depressed, and less likely to use and abuse alcohol. This study is the first qualitative comparison of Jews and Protestants, men and women. It examines whether alcohol-related beliefs are consistent with the alcohol-depression hypothesis, i.e. that positive beliefs about alcohol use and effects are associated with high alcohol use and low depression. MATERIAL AND DISCUSSION: A thematic (interpretive phenomenological) analysis on open-ended question responses, from 70 Jews and 91 Protestants, and on semi-structured interviews with five Jews and four Protestants, identified three salient themes: the importance of retaining self-control; the pleasures of losing inhibitions; and the relations of alcohol-related behaviour to identity. Compared to Protestants, Jews described alcohol-related behaviour as threatening to self-control, loss of inhibition as unenjoyable and dangerous and distinguished between the kinds of drinking behaviours appropriate for Jews and others. Sub-themes for Protestant men were denial that drinking threatens self-control, and appropriateness of going to the pub. CONCLUSIONS: The themes identified are not measurable using published research instruments. Alcohol-related behaviour may be a feature of Jewish identity. The beliefs identified are consistent with the alcohol-depression hypothesis. 相似文献

Human saphenous veins removed from cadaver donors were subjected to proteolytic enzymatic digestion, cross bonding, and heparin bonding. They were tested as small arterial substitutes in dogs. Eight of eleven were successful, persisting without development of stenosis or aneurysm, the longest for eighteen months. In humans, similarly prepared veins were used as arterial bypasses to revascularize ischemic limbs in eleven patients and aneurysmal degeneration of an earlier unmodified allograft bypass in one patient. Distal arterial anastomoses were to the tibial and peroneal arteries. Nine patients who had not undergone previous reconstructive surgery involving the vessel used for distal anastomosis were treated successfully; all remain with healed limbs between three and twelve months after surgery, eight with functioning bypasses. In three patients who had undergone previous operations on the same artery used for distal anastomosis, long bypasses failed, although amputation was avoided in one patient by additional bypass with modified vein to the profunda femoris artery. We conclude that modified saphenous vein allografts are suitable small arterial substitutes. It remains to be seen whether veins will maintain patency for long periods without development of complications. 相似文献
