ABSTRACT
The incidence of augmented renal clearance (ARC) in intensive care patients (ICU) is exceptionally high, and these patients are often co-morbid with infection. The occurrence of ARC will significantly increase the clearance rate of antibiotics, making it difficult for conventional doses to reach effective therapeutic concentrations and affect the patient's anti-infective treatment effect and prognosis. It can be seen that it is crucial to formulate a reasonable dosing regimen for ICU patients with ARC. Regrettably, few reports in China about the adjustment strategy of antibiotic dosing regimens for ARC patients. Therefore, this article reviews the domestic and foreign literature for reference to provide evidence for medical personnel to adjust the dose of antibacterial drugs for such patients.
ABSTRACT
Objective:To determine the clinical features of papillary thyroid microcarcinoma (PTMC) and the risk factors for central compartment lymph node (CCLN) metastasis in PTMC. Methods:Data of 1 401 patients with PTMC who were treated in Tianjin Medi-cal University Cancer Institute and Hospital between January 2014 and December 2014 were retrospectively analyzed. Chi-square test and multivariate Logistic regression analysis were used to study the risk factors. Results:With regard to clinicopathological features, the sex ratio is 1:3.4 in patients with PTMC. CCLN metastasis affected 427 (30.5%) of the total 1 401 patients. Age (χ2=14.587, P6 mm, extracapsular spread, and tumor bilaterality were independently correlated with CCLN metastasis. Conclusion:A prophylactic neck dissection of the central compartment must be considered particularly in male PT-MC patients with age6 mm, extracapsular spread, and tumor bilaterality.
ABSTRACT
Objective To study the effects of percutaneous liver tumor injection combined with the clinical efficacy of transcatheter hepatic artery chemoembolization in the treatment of advanced liver cancer,and to provide ref-erence for clinical treatment.Methods 22 patients using percutaneous liver tumor injection combined with transcath-eter arterial chemoembolization for treatment were selected,with which 1 month follow-up after discharge.Situation of patients with percutaneous liver tumor injection and transcatheter hepatic artery chemoembolization was analyzed,and the changes of the patients in the following -up of survival time,tumor volume and clinical symptoms were also ana-lyzed.Results Among the patients of postoperative recheck after 6 weeks,6 cases were complete remission,there were partial remission in 8 cases,6 cases of stable,2 cases of progress.Follow up to 2013 December,the patients'sur-vival time was 17-82 months,the average survival time was (55.71 ±13.47)months.After treatment,4 cases of patients'tumor diameter reduced 1 -3cm,18 cases of tumor diameter reduced 3 -5cm,19 cases of liver area pain symptoms for more than half a year of remission,3 cases of liver area pain relief time less than half a year.During the follow -up period,12 patients died of multiple organ failure.Conclusion The development of percutaneous liver tumor injection combined with transcatheter hepatic arterial chemoembolization therapy can delay the development of the disease in patients with advanced HCC,and prolong the survival time.
ABSTRACT
ObjectiveTo investigate the feasibility and efficacy of using the hepatoduodenal ligament tension-reduced operation (tension-reduced operation in short) for iatrogenic bile duct injury where the bile duct was severely defective. MethodsBetween March 2006 and May 2009, the authors treated 6 patients with iatrogenic bile duct injury (Bismuth type Ⅱ : 5 patients and type Ⅲ : 1 patient). A no. 7 black silk thread was used to hold the hilar plate tissues and the seromuscular layer of the bulbous part of the duodenum closer together and knots were tied. This method brought the porta hepatis and the duodenal bulb closer together and the hepatoduodenal ligament was shortened. An end to end anastomosis could then be made between the two broken ends of the defective bile duct without tension. ResultsSix patients suffered from bile duct injury and they recovered fully after the tensionreduced operation. There was no complication on follow-up. ConclusionsThe tension-reduced operation was efficacious in the treatment of iatrogenic bile duct injury. This technique should be popularized and more widely used.
ABSTRACT
Objective To explore the clinico-biological characteristics, treatment and prognosis of salivary duct carcinoma. Methods This study included 12 cases of salivary duct carcinoma treated in our hospital. Clinical data were retrospectively analyzed for patients admitted between April 1995 and October 2006. The clinical characteristics, histological features, imaging, therapy methods and prognosis were analyzed. Results Of 12 salivary duct carcinoma, there were 10 males, 2 females. The age of onset ranged from 53 to 73 year old and the average was 56 year old. Physical examination revealed a firm and unboundary mass accompanied by nerve infiltrating symptom. The histological appearance was characterized by solid cell nests with ductal structures and central comedonecrosis. Extensive resection and radical neck dissection was performed in 11 patients, postoperation radiation done in 10 patients and chemotherapy in 3 patients. One year survival rate was 83. 33% , that of 3 years was 41. 67% , and of 5 years was 25. 00% , the median survival time was 36 months. Conclusion Salivary duct carcinoma is a rare malignant salivary tumor and most patients are men. Regional extensive resection and postoperative radiation or chemotherapy are the mainstay of therapy. Lymph node metastases in level Ⅰ ,Ⅱ , Ⅲ are a common finding in patients with SDC and the prognosis is poor.
