Concurrent skull and liver metastases from follicular thyroid carcinoma is a very rare event. We herein present the case of a 72-year-old woman who initially presented with a swelling in the right supraorbital region that proved to be metastasis from a well-differentiated follicular thyroid carcinoma of clear-cell type. The metastatic workup disclosed a huge liver metastasis and an additional metastasis in the left iliac fossa. The treatment of this patient included a total thyroidectomy, an excision of the skull lesion, and the administration of radioiodine therapy, as well as thyroid-stimulating hormone (TSH) suppression therapy. However, the course of her disease was relentless. Although well-differentiated thyroid carcinoma tends to show an excellent course, the presence of metastatic disease leads to a very dismal prognosis.An erratum to this article can be found at 相似文献

In this phase of structure-affinity relationship study of VL-0395, a new anthranilic acid based CCK1 selective antagonist, we propose a series of unnatural aminoacidic derivatives. The result of this work is the identification of a new CCK ligand, which possesses an affinity (IC50 = 35 nm) one order of magnitude greater than the lead and, as a general rule, it points out how the hypothesized receptorial pocket which accommodates the Phe residue allows much more structural modification than that interacting with the N-terminal group. Hence, the modification of the C-terminal pharmacophoric group of our lead VL-0395 can not only enhance the affinity of anthranilic acid derivatives but can modulate the selectivity for one CCK receptor subtype or afford mixed antagonists. 相似文献

In this study, the expression of cyclins D1 and D3, as well as cyclin-dependent kinase inhibitor p27 in thymic epithelial tumors (thymomas) is examined. Histological specimens from 24 patients (11 males and 13 females) were submitted to classification according to WHO criteria. Staining for cyclins D1, D3 and p27 was applied and evaluation was performed for expression of D1, D3 and p27. Eighteen patients presented low-grade thymomas (nine B1, predominantly cortical; three B2, cortical; six B3, well-differentiated thymic carcinoma) and six patients benign thymomas (four A-medullary, two AB-mixed). The p27 expression in patients with benign thymomas was 42+/-26%, whereas in patients with low-grade thymoma, it was 11+/-13%. The expression of cyclins D1 and D3 was 2.8+/-2.7 and 10+/-6% for benign as well as 8.3+/-9.6 and 12+/-10% for low-grade thymomas, respectively. A statistically significant difference was revealed regarding the p27 expression through different grades (analysis of variance P-value 0.00076) and histopathological types of thymomas (P=0.0047). This finding of greater p27 expression in benign thymomas with progressive reduction in higher grades is compatible with observations on other soft tissue and solid tumors suggesting that p27 level decreases during tumor development and progression. 相似文献

In most Balkan countries, with the exception of Greece, transplantation is very rare and equality of access does not exist. In 2003, a Balkan partnership was established called SETNET (South-Eastern European Transplantation Network) for the promotion of transplantation. The objectives are to bring about the diffusion of transplantation techniques and practices in the Balkans, to increase public support for and participation in transplantation, and to eliminate the disparities in access to good health-care. SETNET is already beginning to generate data for an analysis of transplantation-related needs in the Balkans and to accelerate cross-border data exchange in transplantation-related emergencies. In the next few years, a regional training programme will be introduced for all health-care staff involved in transplantation. A regional organ procurement and transplantation network will be set up to utilize the existing telemedicine infrastructure. If successful, it will also prove that telemedicine infrastructures, however modest, can be the backbone for other, far-reaching human networks. 相似文献

Progression of progenitor cells towards neuronal differentiation is tightly linked with cell cycle control and the switch from proliferative to neuron-generating divisions. We have previously shown that the neuronal protein BM88 drives neuroblastoma cells towards exit from the cell cycle and differentiation into a neuronal phenotype in vitro. Here, we explored the role of BM88 during neuronal birth, cell cycle exit and the initiation of differentiation in vivo. By double- and triple-labelling with the S-phase marker BrdU or the late G2 and M-phase marker cyclin B1, antibodies to BM88 and markers of the neuronal or glial cell lineages, we demonstrate that in the rodent forebrain, BM88 is expressed in multipotential progenitor cells before terminal mitosis and in their neuronal progeny during the neurogenic interval, as well as in the adult. Further, we defined at E16 a cohort of proliferative progenitors that exit S phase in synchrony, and by following their fate for 24 h we show that BM88 is associated with the dynamics of neuron-generating divisions. Expression of BM88 was also evident in cycling cortical radial glial cells, which constitute the main neurogenic population in the cerebral cortex. In agreement, BM88 expression was markedly reduced and restricted to a smaller percentage of cells in the cerebral cortex of the Small eye mutant mice, which lack functional Pax6 and exhibit severe neurogenesis defects. Our data show an interesting correlation between BM88 expression and the progression of progenitor cells towards neuronal differentiation during the neurogenic interval. 相似文献

We evaluated the predictive value of several parameters, including the International Staging System (ISS) for myeloma, in patients with advanced disease treated with thalidomide-based regimens (TBR). We analyzed 119 patients, from 3 phase II studies. Patients with pretreatment beta2 microglobulin<3.5 mg/l and albumin 3.5 g/dl were scored ISS stage 1, patients with beta2 microglobulin<3.5 mg/l and albumin<3.5 g/dl or beta2 microglobulin 3.5-5.5 mg/l regardless of albumin levels were scored ISS stage 2, patients with beta2 microglobulin>5.5 mg/l ISS stage 3. ISS stage was 1, 2 and 3 in 45, 32 and 23% of patients respectively. Seventy-four patients (62%) achieved at least partial response. Median progression-free and overall survival were 8 months and 19.5 months respectively. ISS stage, serum LDH and performance status were independent predictive factors for survival. Based on these 3 variables a scoring system was developed with survival times of 38.1, 28.8 and 5.8 months for scores 0, 1 and 2 respectively. The ISS staging system was highly predictive for overall survival of patients with advanced myeloma treated with TBR. With the addition of performance status and serum LDH, a simple scoring system was developed which may help select patients likely to benefit from TBR. 相似文献

OBJECTIVES: To determine the impact of adenotonsillectomy on quality of life (QOL) in children with obstructive sleep disorders (OSDs) before and after surgery. DESIGN: Prospective, observational, before-and-after trial. SETTING: Seven tertiary pediatric otolaryngology practices. PATIENTS: Convenience sample of 101 children (mean age, 6.2 years) with adenotonsillar hypertrophy and OSD scheduled for adenotonsillectomy. INTERVENTION: Adenotonsillectomy was performed in children for OSDs. Quality of life was assessed using the Obstructive Sleep Disorders-6 survey, a validated instrument for detecting QOL change in children with OSDs. Surveys were completed at the initial office visit (visit 1), the day of surgery (visit 2), and at the postoperative office visit (visit 3). Physical characteristics were assessed using tonsillar and orocraniofacial scales (visit 1). Satisfaction with health care decisions was assessed using the Satisfaction With Decision and Satisfaction With Office Visit scales (visit 1). MAIN OUTCOME MEASURES: Short-term changes in QOL before (visits 1 and 2) and after (visits 2 and 3) surgery. RESULTS: Changes in QOL before surgery were trivial or small, and smaller than changes after surgery (mean change score, 0.18 vs 2.3; P<.001). Large, moderate, and small improvements in QOL were seen in 74.5%, 6.1%, and 7.1% of children, respectively. Sleep disturbance, caregiver concern, and physical suffering were the most improved domains, although significant changes also occurred for speech and swallowing problems, emotional disturbance, and activity limitations. Five percent of children had poorer QOL after surgery, but no predictive factors were identified. CONCLUSION: Adenotonsillectomy produces large improvements in at least short-term QOL in most children with OSDs. 相似文献

Chylous ascites is an uncommon condition, which could be due to various causes. We report a case of gross chylous ascites in a patient with cirrhosis and portal vein thrombosis. It is confirmed that gross chylous ascites in a patient with cirrhosis and portal vein thrombosis heralds an ominous prognosis for the patient. Results also demonstrate that common therapeutic interventions confer minimal benefit to the patient, whose survival may be limited to a few months. The use of lymphoscintigraphy as a convenient method for diagnostic exploration of the chylous ascites is emphasized, as it does not lead to complications or adverse effects, and can be readily repeated as needed. 相似文献
