With the use of an offset type tensor for total knee arthroplasties (TKAs), intraoperative soft tissue balance including the joint component gap and ligament balance was measured in 41 varus-type osteoarthritic patients (19 cruciate-retaining [CR] TKAs and 22 posterior-stabilized [PS] TKAs), and the correlations between the intraoperative values and the postoperative values assessed by stress radiographs at extension and flexion were examined at a minimum 5-year follow-up. In CR TKAs, the postoperative soft tissue balances at both angles were significantly correlated with the intraoperative values. In PS TKAs, the postoperative soft tissue balances at extension, not flexion, were significantly correlated with the intraoperative values. In conclusion, the intraoperative condition of the soft tissue balance reflected the postoperative values especially in CR TKAs even at 5-year midterm follow-ups. © 2012 Elsevier Inc. Source

A 67-year-old man with bladder cancer who was treated with transurethral resection of bladder tumour(TUR-Bt)and chemotherapy at the age of 59 years was diagnosed as having urothelial cancer by biopsy 8 years later. Detailed examination revealed the presence of synchronous triple cancer, with hepatocellular cancer and gastric cancer. Subsequently, semi-total gastrectomy, partial hepatectomy(S6), radio frequency ablation(S5, S7), and cholecystectomy were performed. Histologically, the gastric tumor was a moderately differentiated tubular adenocarcinoma, the hepatic tumor was a moderately differentiated hepatocellular carcinoma, the bladder tumor was a transitional cell carcinoma, and the ureteral tumor was an urothelial carcinoma.

We report two rare cases of extraparotid Warthin's tumor arising from the lateral cervical lymph node. Two 79-year-old men presented with the right lateral neck masses without tenderness and referred pain. Both patients underwent surgical excisional biopy of the tumors for diagnosis. Those masses were easily extirpated without adhesion and there were no communication with the parotid gland. Those specimens were dark-red, slight irregular, slight elastic hard nodular masses. Histopathological examinations of two cases revealed Warthin's tumor. No reccurences were observed after the surgery until now in both cases. Source

We evaluated the outcome of 76 cases of laryngeal cancer primarily treated in our hospital from January 2001 to December 2010. Supraglottic cancer was found in 21 cases (27.6%), glottic cancer in 54 cases (71.1%), and subglottic cancer in 1 case (1.3%). The five-year survival rates were as a whole 82.9%, supuraglottic type 57.2%, glottic type 92.9%, and stage I 100%, stage II 83.6%, stage III 57.1%, stage IV 35.7%, respectively. The five-year organ preservation rates were 82.4% in T1, 61.4% in T2, respectively. Concurrent chemoradiotherapy is important for improvement of survival and organ preservation of laryngeal cancer.

In the carotid artery plaque diagnosis, it is said that properties evaluation is important. For this inspection, it is general to use electrocardiogram (ECG)-trigger-dark blood (DB)-fat suppression (fs)-turbo spin echo (TSE)-T1 weighted image (T1WI), T2WI, and magnetization prepared rapid gradient echo (MPRAGE) methods though many problems still remain. This time, a comparative study of the carotid artery plaque diagnosis that used the sampling perfection with application optimized contrasts was made. This used different flip angle evolutions method sampling perfection with application optimized contrasts using different flip angle evolutions (SPACE) method that was 3 dimension (3D) imaging procedure that used variable flip angle with the law so far. The subjects were normal volunteers, handmade phantoms changed by T1 and T2 value, and the five patients on five cases who had taken carotid endoarterectomy (CEA) (male, mean 70.6 yr). Findings by the pathologist were obtained for the CEA enforcement patient. There is an excellent result in the contrast ratio by phantom, the signal intensity ratio of a clinical patient, and the comparison with pathological findings. The SPACE method can solve various problems, be evaluated by a properties evaluation of the plaque, a grasp of the range, and an arbitrary section, and be devised as a useful imaging procedure.
