AIM： To examine surgical specimens of pancreas with either chronic pancreatitis or pancreatic cancer in order to study whether ductal hyperplasia and dysplasia in pancreas represent precursor lesions for pancreatic cancer. METHODS： We examined expression of Ki-67, CEA, p53, and K-ras, in the surgical specimens of pancreas with adenocarcinomas （n = 11） and chronic pancreatitis （n = 12）. Cellular proliferation was assessed by Ki-67 proliferation index using the proliferation marker Ki-67. In specimens with pancreas cancer, we divided pancreas epithelium into normal （n = 7）, ductal hyperplasia （n = 3）, dysplasia （n = 4）, and cancerous lesion （n = 11） after hematoxylin and eosin staining, Ki-67, and CEA immunohistochemical staining. In cases with chronic pancreatitis, the specimen was pathologically examined as in cases with pancreas cancer, and they were also determined as normal （n = 10）, ductal hyperplasia （n = 4）, or dysplasia （n = 5）. p53 and K-ras expression were also studied by immunohistochemical staining. RESULTS： In pancreatic cancer, the Ki-67 index was 3.73±3.58 in normal site, 6.62±4.39 in ductal hyperplasia, 13.47：1：4.02 in dysplasia and 37.03±10.05 in cancer tissue, respectively. Overall, p53 was positive in normal ducts, ductal hyperplasia, dysplasia, and carcinoma cells in 0 of 14 （0%）, 0 of 7 （0%）, 7 of 9 （78%）, and 10 of 11 （91%）, respectively, and K-ras was positive in 0 of 8 （0%）, 1 of 3 （33%）, 4 of 6 （67%）, 4 of 5 （80%）, respectively. CONCLUSION： Our results favorably support the hypothesis that ductal hyperplasia and dysplasia of the pancreas might be precursor lesions for pancreas cancer. Further evaluation of oncogenes by the molecular study is needed.

Giant choledocholithiasis treated by mechanical lithotripsy using a gastric bezoar basket

World Journal of Gastroenterology 2012年第25期18卷 3327-3330页

Mechanical lithotripsy （ML） is usually considered as a standard treatment option for large bile duct stones. However, it is impossible to retrieve oversized stones because the conventional lithotripsy basket may not be able to grasp the stone. However, there is no es- tablished endoscopic extraction method for such gi- ant stone removal. We describe a case of successful extraction of a 4-cm large stone using a gastric bezoar basket. A 78-year-old woman had suffered from upper abdominal pain for 20 d. Contrast-enhanced computed tomogram revealed a 4-cm single stone in the distal common bile duct （CBD）. Endoscopic stone retraction was decided upon and endoscopic papillary balloon dilation was performed using a large balloon. An at- tempt to capture the stone using a standard lithotripsy basket failed due to the large stone size. Subsequently, we used a gastric bezoar basket to successfully capturethe stone. The stone was fragmented into small pieces and extracted. The stone was completely removed after two sessions of endoscopic retrograde cholangio- pancreatography; each of which took 30 rain. No com- plications occurred during or after the procedure. The patient was fully recovered and discharged on day 11 of hospitalization. ML using a gastric bezoar basket is a safe and effective retrieval method in select cases, and is considered as an alternative nonoperative option for the management of difficult CBD stones.

Usefulness of radial extracorporeal shock wave therapy for the spasticity of the subscapularis in patients with stroke： a pilot study

引用

Chinese Medical Journal 2013年第24期126卷 4638-4643页

作者： YongWook Kim Ji Cheol shin jeong-Gyu Yoon Yong-Kyun Kim Sang Chul Lee Department and Research Institute of Rehabilitation Medicine Yonsei University College of Medicine Seoul Republic of Korea Department of Physical Medicine & Rehabilitation MyongjiHospital Kwandong University College of Medicine GyunggiRepublic of Kore~

Background There are not many studies about treatment of shoulder spasticity. Although botulinum toxin injection has been reported to be effective for shoulder spasticity, the effectiveness was judged by pain and limited motion change, but not the spasticity itself. Shoulder spasticity is considered to play an important role in hemiplegic frozen shoulder. However, the subscapularis muscle, unlike the pectoralis major muscle, is located deep beneath scapula, where conventional injection is difficult to perform. As extracorporeal shock wave therapy （ESWT） has been reported to be effective for spasticity relief, and we thought spasticity of subscapularis muscle located deep beneath the scapula would be a good candidate for ESWT treatment. This study was to evaluate the beneficial effects of radial ESWT （rESWT） on spastic subscapularis muscle in stroke patients. Methods This is an uncontrolled, prospective, unicenter, clinical pilot study. Stroke patients （n=57; mean age 55.4 years） with spastic shoulders were recruited between June 2011 and February 2012 at the University Rehabilitation Hospital. rESWT was administered to each patient every two or three days for two weeks （five total treatments）. Evaluation consisted of 11 measurements for each patient; at the start of each of the five treatments and once per week during the following six weeks. Spasticity was measured at external rotator muscles of the shoulder using the modified Ashworth scale （MAS）, and passive range of motion （ROM） of the shoulder in external rotation was recorded. Pain was measured using a visual analogue scale （VAS） during passive ROM of the shoulder in external rotation, and was additionally recorded for patients who preserved cognitive and communicative ability （Pain group）. Results Reduction in MAS and VAS and improvement of ROM during and after rESWT treatments were prominent compared to baseline. The reduction in MAS and VAS and improvement of ROM continued four weeks after the last treatmen
