Reducing the Occupational Risk of Infections for the Surgeon: Multicentric National Survey on More Than 15,000 Surgical Procedures 总被引:2,自引:0,他引:2

The objective of this study was to find the incidence of accidental exposures to blood and body fluids among surgeons during operations and to describe their dynamics. A probabilistic model was also used to predict the cumulative 30-year risk to the surgeon of contracting hepatitis B and C viruses (HBV, HCV) or human immunodeficiency virus (HIV) infection and estimate the effect of preventive strategies in reducing this risk. A multicentric prospective survey, based on self-administered questionnaires, was conducted during a period of 6 months in 39 Italian hospitals. An accidental exposure to blood or body fluids occurred in 9.2% of 15,375 operations. In about 2% of procedures a parenteral-type injury, such as actual skin puncture or eye contamination, was suffered by the operating surgeon. A needle-stick injury was the commonest accident, and its occurrence was found to vary with the phase of the procedure and its length. The current lifetime risk of acquiring HBV, HCV, and HIV infection in our regions was estimated to be as high as 42.7%, 34.8%, and 0.54%, respectively. The adoption of preventive strategies is expected to reduce this risk to 21% for HBV, 16.6% for HCV, and 0.23% for HIV infection. Active immunization of surgeons against HBV is strongly recommended. The case is also made for the use of a face-shield combined with a permanent change in our surgical practice capable of reducing the current high rate of parenteral injuries. 相似文献

A retrospective study of 103 thymectomies examines the effects of the integration of surgical and medical therapy in patients affected by myasthenia gravis accompanied by thymoma. An extended thymectomy via a median longitudinal sternotomy was used in 102 patients. The operative mortality was 4.85% (5/103 patients), the 10-year survival rate was 78% with a recurrence rate of 3.06% (3/98). Neoplastic infiltration and postoperative radiotherapy did not influence the survival rate. There was no correlation between a preoperative Osserman's class better than III and postoperative outcome. The improvement of medical treatment, and anaesthesiological and intensive care techniques resulted in a decrease of the operative mortality and long-term death rate during the last 10 years of our 20-year series. Extended thymectomy via sternotomy is the best intervention in patients with myasthenia gravis associated with thymoma judged by the low operative mortality and the favorable 10-year survival rates. 相似文献

Few reports of the Western countries have investigated the value of palliative surgery for stomach cancer. The aim of this study was to evaluate the results of palliative surgery in a large series of patients affected by gastric carcinoma, consecutively treated by the same surgical team. The hospital records of 305 patients affected by gastric cancer who did not undergo surgical treatment or who underwent a palliative surgical procedure at our unit between 1981 and 1995 were reviewed. Univariate and multivariate analyses were used to calculate the 5-year survival probabilities with respect to the following variables: demographic data, tumor location and gross appearance, spread of the disease, histological type according to P. Lauren, and type of treatment. Multivariate logistic regression analysis showed that resectional surgery and tumor spread limited to local sites were independently associated with better survival. The study indicates that even though there are host-related factors that govern survival in far-advanced stomach cancer, the type of surgery can have a significant effect on prognosis; resectional surgery should be undertaken whenever possible in such patients. 相似文献

Hypothalamitis: a diagnostic and therapeutic challenge 总被引:1,自引:0,他引:1
Antonio?BianchiEmail author Marilda?Mormando Francesco?Doglietto Linda?Tartaglione Serena?Piacentini Libero?Lauriola Giulio?Maira Laura?De Marinis 《Pituitary》2014,17(3):197-202
To report an unusual case of biopsy-proven autoimmune hypophysitis with predominant hypothalamic involvement associated with empty sella, panhypopituitarism, visual disturbances and antipituitary antibodies positivity. We present the history, physical findings, hormonal assay results, imaging, surgical findings and pathology at presentation, together with a 2-year follow-up. A literature review on the hypothalamic involvement of autoimmune hypophysitis with empty sella was performed. A 48-year-old woman presented with polyuria, polydipsia, asthenia, diarrhea and vomiting. The magnetic resonance imaging (MRI) revealed a clear suprasellar (hypothalamic) mass, while the pituitary gland appeared atrophic. Hormonal testing showed panhypopituitarism and hyperprolactinemia; visual field examination was normal. Pituitary serum antibodies were positive. Two months later an MRI documented a mild increase of the lesion. The patient underwent biopsy of the lesion via a transsphenoidal approach. Histological diagnosis was lymphocytic “hypothalamitis”. Despite 6 months of corticosteroid therapy, the patient developed bitemporal hemianopia and blurred vision, without radiological evidence of chiasm compression, suggesting autoimmune optic neuritis with uveitis. Immunosuppressive treatment with azathioprine was then instituted. Two months later, an MRI documented a striking reduction of the hypothalamic lesion and visual field examination showed a significant improvement. The lesion is stable at the 2-year follow-up. For the first time we demonstrated that “hypothalamitis” might be the possible evolution of an autoimmune hypophysitis, resulting in pituitary atrophy, secondary empty sella and panhypopituitarism. Although steroid treatment is advisable as a first line therapy, immunosuppressive therapy with azathioprine might be necessary to achieve disease control. 相似文献

Myeloid sarcoma (MS) is a localized extra‐medullary tumor mass of immature myeloid cells, arising de novo or related to acute myeloid leukemia, of which it can be a forerunner, a coinciding or late event. Less commonly, MS represents an acute blastic transformation of myelodysplastic syndromes or myeloproliferative neoplasms. This rare condition commonly consists of a proliferation of more or less immature cells with a myeloid immunophenotype, very exceptional cases showing a megakaryoblastic or erythroid differentiation. The most common localization of MS is the skin, lymph node, soft tissues and bones, but CNS involvement is exceedingly rare, with no cases reported in the sellar region. We report a 54‐year‐old man, affected by myeloproliferative neoplasm, JAK2 V617F‐positive of 13 years duration, who acutely presented with a third cranial nerve palsy; neuroradiology documented a space‐occupying lesion at the level of the sellar, upper clival and right parasellar regions, that was sub‐totally removed with a trans‐sphenoidal approach. The histological examination documented a proliferation of large, blastic cells, frequently multinucleated; a diagnosis of MS with megakaryoblastic differentiation, arising in a background of chronic idiopathic myelofibrosis, was suggested by immunohistochemistry, owing to CD42b, CD45, CD61 and LAT (linker for activation of T cells) positivity. In addition, homozygous JAK2 V617F mutation was detected from the myeloid sarcoma specimen. A few weeks after surgery, an acute blastic leukemic transformation occurred and, despite chemotherapy, the patient died 2 months after surgery. To the best of our knowledge, this is the first MS case with megakaryoblastic differentiation arising within the CNS. 相似文献

Gastrointestinal stromal tumours, though rare, are the most common mesenchymal neoplasms affecting the gastrointestinal tract. The most frequent sites of origin are the stomach and the small bowel, but they can occur anywhere in the gastrointestinal tract. Mesenteric and retroperitoneal forms have been described. The Authors present their personal experience with the treatment of gastrointestinal stromal tumours, with particular reference to the broad spectrum of clinical presentations and to the consequent therapeutic implications. We report on a retrospective analysis of the clinical presentations and courses, surgical management and pathological features of 27 patients with such tumours treated in our institution from 1993 to 2005. The variables analysed were the morphological and clinical characteristics of the tumours, demographic data, type of surgical treatment and postoperative course. Long-term survival was evaluated on the basis of clinical and/or telephonic follow-up in all patients. One tumour was located in the oesophagus, 14 in the gastric area, 7 in the small bowel, 2 in the colon-rectum, and 3 in the peritoneum. All patients studied received radical surgical treatment. In 7 patients surgical resection was extended to other organs. No postoperative mortality or major postoperative complications were observed. Twenty-two patients are still alive at follow-up. Three patients died as a result of neoplastic relapse and 2 of other causes. The median survival was 36 months. The actuarial 3- and 5-year survival rates were 89.7% and 67.8%, respectively. Our experience indicates that the site of origin of gastrointestinal stromal tumours with their broad spectrum of clinical presentations may influence both the therapeutic choice (neoadjuvant utilisation of imatinib mesylate) and the surgical treatment (wedge resection vs enlarged operations). 相似文献

Evaluation of prognostic factors of adenocarcinoma of Vater’s ampulla is still a matter of debate. The aim of this study was to evaluate retrospectively factors that influence early and long-term outcomes in a 20-year single-institution experience on ampullary carcinoma. A total of 94 consecutive patients with ampullary carcinoma or adenoma with severe dysplasia were managed from 1981 to 2002. Among them, 64 underwent pancreatoduodenectomy, and the remaining 30 submitted to surgical (n = 5) or endoscopic (n = 25) palliative treatment. Demographic, clinical, and pathologic data were collected, and a comparison was made between patients who did or did not undergo resection. Standard statistical analyses were carried out in an attempt to establish a correlation between clinical variables, intraoperative and pathologic factors, and survival in patients with resection. A total of 85 (90.4%) patients had potentially resectable lesions due to the extent of the tumor, but only 64 (68%) underwent curative resection. The surgical morbidity rate was 34.3%. Postoperative mortality was 9.3%, with no deaths among the 38 more recently treated patients. Median survivals were 9 and 54 months for nonresected and resected patients, respectively. The overall 5-year survival was 64.4% for patients undergoing pancreatoduodenectomy. Survival was found to be significantly affected by resection, tumor size, tumor grade, and tumor infiltration. Patients with negative lymph nodes show a trend toward longer survival. In a multivariate analysis, only the depth of tumor infiltration influenced patient survival.Pancreatoduodenectomy is the treatment of choice for ampullary carcinoma and adenomas with high-grade dysplasia, with a good chance of long-term survival. Surgical resection remains the most important factor influencing outcome. 相似文献
