Medullary thyroid carcinoma (MTC) is an uncommon malignancy of neuroendocrine origin derived from the parafollicular C cells. Although infrequent, the interest in this cancer exceeds its incidence owing to its distinctive features and its characteristic association with other endocrine tumors. Although the majority of MTCs are sporadic, hereditary varieties occur in isolation or as a part of multiple endocrine neoplasia type 2 syndrome (MEN 2). Currently, complete surgical resection of the tumor and nodal metastases with a curative intent remains the mainstay of therapy. The role of adjuvant therapy is limited, although radiotherapy and newer targeted therapies are routinely used for metastatic disease. The lack of consensus in the available guidance regarding the most appropriate diagnostic, therapeutic and follow-up strategies has caused substantial variability in clinical practice. Therefore, this review summarizes the latest available evidence and guidelines on the management of MTC with an emphasis on diagnosis, surgical treatment and follow-up. 相似文献

Huxley's Island: a novel (1962) is a parable on "realistic idealism"--set in an imaginary island situated in the Indian ocean between Sri Lanka and Sumatra, called Pala. The characters in the story include a doctor, a nurse and several patients. The general importance of health as a basic human need is well recognised. Vis medicatrix naturae, the natural healing powers of the body, are taken account of, along with psychotherapy and drugs. Prevention of illness is emphasised and doctors get paid for keeping people well. Since health and illness are influenced by a multitude of factors, "we attack on all the fronts at once ... from diet to auto-suggestion, from negative ions to medication". 相似文献

Recent literature reports an increased incidence of venous thrombosis following thalidomide use in the treatment of diseases with disease-related thrombotic risks such as malignancy, as well as concomitant use with chemotherapy and/or systemic corticosteroids. We report a case of deep vein thrombosis (DVT) and pulmonary embolism (PE) following thalidomide use in a patient with erythema nodosum leprosum (ENL) reaction who was concurrently treated with prednisolone, as well as a review of relevant literature. 相似文献

The bipartite RNA genome of Red clover necrotic mosaic virus (RCNMV) is encapsidated into icosahedral virions that exist as two populations: i) virions that co-package both genomic RNAs and ii) virions packaging multiple copies of RNA-2. To elucidate the packaging mechanism, we sought to identify the RCNMV origin of assembly sequence (OAS). RCNMV RNA-1 cannot package in the absence of RNA-2 suggesting that it does not contain an independent packaging signal. A 209 nt RNA-2 element expressed from the Tomato bushy stunt virus CP subgenomic promoter is co-assembled with genomic RNA-1 into virions. Deletion mutagenesis delimited the previously characterized 34 nt trans-activator (TA) as the minimal RCNMV OAS. From this study we hypothesize that RNA-1 must be base-paired with RNA-2 at the TA to initiate co-packaging. The addition of viral assembly illustrates the critical importance of the multifunctional TA element as a key regulatory switch in the RCNMV life cycle. 相似文献
