The principal reason for such a response is the mobilization of amino acids and the production of glucose to provide energy for the cells involved in the host immune response and wound repair. The endocrine hormones, eg, cortisol, the catecholamines, and glucagon, are largely responsible for these effects. Insulin and growth hormone administration can produce anabolic effects to block the loss of body protein. Administration of specific amino acids, such as glutamine, also appears to be beneficial. However, the hypermetabolic state goes beyond derangement of endocrine hormone levels. Although the cytokines are also important mediators, it is not clear how these mediators, in concert with hormonal changes, produce all of the manifestations of the hypermetabolic state seen in stress.</p>","PeriodicalId":79397,"journal":{"name":"Current opinion in general surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18589121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For melanomas 1 to 4 mm thick, the results of the Intergroup Melanoma Trial in the United States suggest that a 2-cm margin is adequate. European studies indicate that a 1-cm margin may be satisfactory for all melanomas 2 mm thick or less. Elective node dissection is not indicated for melanomas less than 1 mm thick. Survival benefit has not been shown in two prospective studies, although retrospective studies suggest that elective node dissection improves the survival of patients with intermediate melanomas 1 to 4 mm thick. Elective dissection is more likely to benefit patients at high risk of harboring microscopic disease in the regional nodes, such as men with melanomas 1 to 4 mm thick or women with 2- to 4-mm lesions. For melanomas thicker than 4 mm, elective dissection is generally not indicated, except for staging purposes in the context of a protocol because the predominant mode of dissemination in this group is hematogenous. Therapeutic dissection is indicated in all patients with clinically suspicious regional nodes and no evidence of distant dissemination. In doubtful cases, a biopsy of the node may be done, to be followed, if the results are positive, with the definitive procedure. Although the majority of these patients relapse, the surgical treatment offers appreciable 5-year survival rates which cannot, at present, be attained by other modalities. Some evidence suggests that prompt detection of palpable regional nodes and thorough dissection improve the survival rates.</p>","PeriodicalId":79397,"journal":{"name":"Current opinion in general surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18589246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Similarly, assessing prognosis in cases of malignancy is problematic. Traditionally, histologic criteria, including grade of the tumor, architectural features, and cytologic appearance, have been used to predict biologic behavior. In addition, clinical scoring systems may be useful in assigning prognosis in individual cases. Examination of the DNA profile of individual cells by flow cytometry may correlate with the aggressiveness of the tumor. Recent developments in molecular genetics have yielded genetic markers that may be useful in diagnosis and prognosis as well as illuminating the pathogenesis of endocrine neoplasia.

Although small bowel tumors are traditionally difficult to diagnose, a heightened index of suspicion should be combined with improved diagnostic techniques to increase yield and decrease delays in identification. The management of bioactive carcinoid tumors has rapidly advanced over the past year. Increasing experience with the stable somatostatin analogue octreotide has enabled regulation of hormonal secretion by these tumors both chronically and during acute \"carcinoid crisis.\" In addition, early identification may be facilitated by the use of isotopically labeled variants of the compound.

Surgical infections: blocking the mediator cascade responsible for sepsis and septic shock. 手术感染:阻断导致败血症和感染性休克的介质级联。

{"title":"Surgical infections: blocking the mediator cascade responsible for sepsis and septic shock.","authors":"M P Fink","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>In conventional usage, \"sepsis\" denotes a clinical syndrome caused by excessive release of a variety of proinflammatory mediators, including tumor necrosis factor alpha, interleukin-1, and metabolites of arachidonic acid. Because this condition can be precipitated by infectious or noninfectious causes (eg, acute pancreatitis), a recent consensus conference has advocated replacing the term sepsis with the phrase systemic inflammatory response syndrome. Improvements in our understanding of the pathophysiologic basis for systemic inflammatory response syndrome have resulted in the development of a number of novel approaches for treating, preventing, or limiting its deleterious consequences. Although much of this work remains confined to the laboratory, several of these approaches are undergoing (or recently have undergone) clinical evaluation. Among these are the use of monoclonal antibodies against endotoxin, monoclonal antibodies against tumor necrosis factor, recombinant proteins that antagonize the effects of or bind to circulating interleukin-1 or tumor necrosis factor, and drugs that inhibit the enzyme cyclooxygenase, which is responsible for the formation of certain key metabolites of arachidonic acid.</p>","PeriodicalId":79397,"journal":{"name":"Current opinion in general surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18589476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
