The association between thyrotoxicosis and thyroid cancer is a classical, rare and controversial entity. Within their series of eleven such cases the authors dissociate two distinct groups from clinical and pathological viewpoint. The first category is represented by one case of follicular thyroid cancer with clinically and biologically confirmed hyperthyroidism. The second group includes ten patients with thyrotoxicosis (three cases with Graves' disease, four with toxic multinodular goiter and three with toxic adenoma) and associated unsuspected occult or nodular carcinoma. None of these patients had received previous treatment with radioiodine. In all cases the diagnosis was established by pathological examination of the surgical specimen. Surgery is the treatment of choice in these lesions, the presence of carcinoma imposing the extent of operation. Five near total thyroidectomies and three near total lobectomies with ablation of the isthmus was performed in our cases associated with appropriate additional measures: TSH suppression or 131I treatment. Post surgical results were satisfactory without morbidity or mortality. The long-term survey was good (seven cases alive after 5 years). 相似文献

Improved preoperative functional and topographic diagnostic techniques and availability of intra-operative hormone monitoring, stimulated the introduction of video-assisted minimally invasive operations in parathyroid and thyroid surgical pathology. The first cases of such pathology operated on in our clinic are presented. The first one is a 62 year old man with renal hyperparathyroidism consecutive to a chronic renal insufficiency and hemodialysis from five and three years respectively. The technique of a minimally invasive gapless resection of all four "adenomised" parathyroid glands using laparoscopic and classic instruments is described. Fragments of one gland are implanted in the left forearm musculature. The second case was a 48 year old woman with a three cm diameter right toxic adenoma. With a lateral 15 mm incision, dissociation of the musculature and adequate moving of the retractors the excision of the thyroid nodule was done in 25'. The video-assisted minimally invasive approach allows magnification and adequate identification and removal of endocrine secreting tissues in thyroid and parathyroid pathology. The authors believe that these techniques represent a feasible and attractive alternative to conventional surgery. 相似文献

The medullar thymoma is a rare and distinctive epithelial thymoma, a thymic tumor characterized histologically by a mixture of spindle epithelial cells and lymphoid cells. We are presenting this tumor to a 68 years old man, admitted at CCI, for a mediastinal tumor, treated by tumorectomy, for revealing the cytological, histological and immunohistochemical characteristic features. The surgical biopsy was prepared by using usual histological techniques and haematoxilin eosin and Van Gieson stainings. We are discussing the relation between the thymoma clinicopathological and prognostic features, resulting a clear correlation between histological type and clinical study. We also pointed the Muller-Hermelink thymoma histological subtypes and their correspondence with OMS histological types, reflecting realistically the thymoma clinical behavior. 相似文献

The prophylactic use of antibiotics in the purpose of decreasing the frequency and severity of surgical infections is still controversial. The practical need of defining the concept of antibiotic prophylaxis gave rise to numerous polemics in the literature. This paper presents a retrospective study on 103 cases whom diagnostics were colon and rectum cancer, that were operated in the IV-th Surgical Clinic in 1993-2002 period; at these patients was done antibiotic prophylaxis local and systemic before, during and after operating. This method made possible the registration of a minimum number of cases with surgical infection (7 cases, representing only 7% of the operated patients): a case (1%) with peritoneal collection (needing the surgical evacuation of this collection) and in 6 cases, parietal superficial infections, which imposed the prolong of drainage for almost 7 days. Starting from the basic principles of antibiotic therapy, this paper aims at outlining practical guidelines for a judicious antibiotic prophylaxis. 相似文献

An unusual association between an arachnoid cyst and a decompensated pyloric stenosis in a three years-old boy is presented. The little patient was admitted into hospital with haematemesis, melena, influenced generally condition and acute posthemorrhagic anaemia following aspirin intake for hypertermia. Specific intensive care was successful and the little patient was discharged but without an upper digestive endoscopy(parents refusal, technical reasons). After one week he returned with progressive worsening vomitings and an intracranial hypertension was suspected. CT documented an arachnoid cyst in the right middle cranial fossa and the patient is directed to the Neurosurgical Clinic where a cyst fenestration was done. Subsequent to operation the vomitings reinstaled with severe dehydration and an upper GI series showed a decompensated pyloric stenosis. He was operated on underwenting an antrectomy. Finally the child recovered with good short and long-term evolution. The coincidental presence of an intracranial congenital mass and a complicated aspirin-induced peptic ulcer in this young patient, misleaded us and in the lack of an early endoscopy an intempestive neurosurgical operation was initially done. 相似文献

Perceptual objects often comprise a visual and auditory signature that arrives simultaneously through distinct sensory channels, and cross-modal features are linked by virtue of being attributed to a specific object. Continued exposure to cross-modal events sets up expectations about what a given object most likely "sounds" like, and vice versa, thereby facilitating object detection and recognition. The binding of familiar auditory and visual signatures is referred to as semantic, multisensory integration. Whereas integration of semantically related cross-modal features is behaviorally advantageous, situations of sensory dominance of one modality at the expense of another impair performance. In the present study, magnetoencephalography recordings of semantically related cross-modal and unimodal stimuli captured the spatiotemporal patterns underlying multisensory processing at multiple stages. At early stages, 100 ms after stimulus onset, posterior parietal brain regions responded preferentially to cross-modal stimuli irrespective of task instructions or the degree of semantic relatedness between the auditory and visual components. As participants were required to classify cross-modal stimuli into semantic categories, activity in superior temporal and posterior cingulate cortices increased between 200 and 400 ms. As task instructions changed to incorporate cross-modal conflict, a process whereby auditory and visual components of cross-modal stimuli were compared to estimate their degree of congruence, multisensory processes were captured in parahippocampal, dorsomedial, and orbitofrontal cortices 100 and 400 ms after stimulus onset. Our results suggest that multisensory facilitation is associated with posterior parietal activity as early as 100 ms after stimulus onset. However, as participants are required to evaluate cross-modal stimuli based on their semantic category or their degree of congruence, multisensory processes extend in cingulate, temporal, and prefrontal cortices. 相似文献

Although hematopoietic cell transplantation (HCT) is generally accomplished using a single donor, multiple donors have been used to enhance the speed of engraftment, particularly in the case of umbilical cord blood grafts. Here we posed the question in the canine HCT model whether stable dual-donor chimerism could be established using 2 DLA-identical donors. We identified 8 DLA-identical littermate triplets in which the marrow recipients received 2 Gy total body irradiation followed by marrow infusions from 2 donors and postgrafting immunosuppression. All 8 dogs showed initial "trichimerism," which was sustained in 5 dogs, while 2 dogs rejected one of the allografts and remained mixed chimeras, and 1 dog rejected both allografts. Immune function in one trichimeric dog, as tested by mixed leukocyte culture response and antibody response to sheep red blood cells, was found to be normal. Five dogs received kidney grafts from one of their respective marrow donors at least 6 months after HCT without immunosuppressive drugs, and grafts in 4 dogs are surviving without rejection. In summary, following nonmyeloablative conditioning, simultaneous administration of marrow grafts from 2 DLA-identical littermates could result in sustained trichimerism, and immunologic tolerance could include a kidney graft from one of the marrow donors. 相似文献
