Nowadays shoulder ultrasound is commonly used in the assessment of shoulder diseases and is as accurate as magnetic resonance imaging in the detection of several pathologies. Operator dependence is the main disadvantage of shoulder ultrasound. After adhering to a strict examination protocol, good knowledge of normal anatomy and pathologic processes and an awareness of common pitfalls, it can be used as a focused examination providing rapid, real-time diagnosis, and treatment by ultrasound-guided interventions in desired clinical situations. Also shoulder ultrasound can help the surgeon decide whether treatment will be surgical or nonsurgical. If arthroscopy is planned, sonographic findings help to counsel patients regarding surgical and functional outcomes. If a nonsurgical approach is indicated, ultrasound can be used to follow patients. This review article presents the examination techniques, the normal sonographic appearances and the main pathologic conditions found in shoulder ultrasound. And also addresses a simplified approach to scanning and ultrasound-guided intervention. Knowledge of optimal techniques, normal anatomy, dynamic maneuvers, and pathologic conditions is essential for optimal performance and interpretation of images.

Acupuncture with gold needle insertion is utilized in Oriental medicine, and the effect of therapy is represented by anti-inflammatory and analgesic function, But sometimes the needle is erroneously inserted into abdominal organs, and then it may cause dangerous complications. We report a case of multiple gold needles in the abdominal organs without having definete clinical symptoms.

Pancreas lipomatosis is definde as fatty replacement of pancreatic acinar cells. Of the nine cases evaluated, seven cases (77.8%) of lipomatosis were limited inbody and tail, one case (11.1%) showed total lipomatosis excluding uncinate process and the remaining one case (11.1%) only in tail. As to the severity of lipomatosis, complete fat replacement in body and tail was found in four cases (44.4%), incomplete body and complete tail involvement in two (22.2%), incomplete body and tail, complete all except uncinate process, and complete tail involvements were found in one case (11.1%) each. Associated or predisposing factors included three diabetes mellitus (33.3%) combined with pancreas divisum, pancreas lithiasis and cholelithiasis respectively, hepatitis (22.2%) in two, and pseudocyst (11.1%) in one case, but in three cases (33.3%) nothing was found. In conclusion, pancreas lipomatosis was easily diagnosed by the abdominal CT and it was associated or predisposed by several e tities but had no major clinical symptoms, such as pancreatic insufficiency.

OBJECTIVE: There are various surgical approaches to far-lateral lesions in the L5-S1 intervertebral space. Of these is the validity of a paramedian tangential approach is being investigated in this study. METHODS: A retrospective study was conducted on 25 patients who had been diagnosed as having a far-lateral L5-S1 disc herniations, osteophyte, costal process hypertrophy, and had undergone a paramedian tangential approach from November 1999 through December 2003. The degree of symptoms and improvement were compared via the visual analog pain scale, before and after surgery. RESULTS: This study included 4 males and 21 females with a mean age of 62+/-11.8 years old. The average follow-up period after surgery was 8.2+/-2.7 months. The visual analog pain scale taken before surgery was 6.7+/-1.1 points, while the post-surgical scale was 2.4+/-0.9 points showing a significant decrease (p<0.05). There were no complications that developed during surgery. CONCLUSION: A paramedian tangential approach is less invasive in the soft tissue than that of the median approach. This approach may effectively reduce nerve root compression and expand intervertebral foramens, and is devoid of the risk of spinal instability after surgery. The authors suppose that a paramedian tangential approach is quite an effective technique to relieve compression in the far-lateral L5-S1 intervertebral space.

Twenty seven patients with known rectal cancer were evaluated with CT and CT findings were correlated with surgical and pathologic results on the aspect of perirectal fat infiltration and lymph node involvement. The accuracy in assessment of perirectal fat infiltration was 77.8% (21 of 27); sensitivity, 73.3% (11 of 13); specificity, 83.3% (10 of 12). In the detection of lymph node involvement, lymph nodes were divided into five groups according to the arterial teritories. Overall accuracy in the evaluation of lymph node involvement was 86.7%. Accuracy of peritumoral lymph node involvement was 51.9% (14 of 27); sensitivity, 42.9%(9 of 21); specificity 83.3% (5 of 6). Accuracy of internal iliac lymph node involvement was 88.9% (24 of 27); sensitivity, 85.7% (6 of 7); specificity, 90.0% (18 of 20). Of the common and external iliac lymph node, accuracy was 100% (27 of 27); sensitivity, 100% (2 of 2); specificity, 100% (25 of 25). Of the aortic bifurcation and mid sacral lymph node, accuracy was 92.6% (25 of 27); sensitivity, 50% (2 of 4); specificity, 100% (23 of 23). In regard to the inferior mesenteric lymph node, no lymphadenopathy was found on CT and pathologic results. In conclusion, CT has limited value in evaluating rectal cancer but with the satisfactory outcome in assessment of perirectal fat infiltration and lymph node, involvement except peritumoral node preoperative CT is useful in the evaluation of rectal cancer.

PURPOSE: Biliary dyskinesia was considered as a wastebasket of quasi-biliary disease which could not be clearly explained under the basis of morphologic pathology. This entity was a source of confusion because of misconception and poor understanding. Recent introduction of biliary manometric technique enlightened some of these disorders. We evaluated the cholangiographic morphology of these disorders to clarify and to characterize the some characteristic findings, subsequently in order to help the diagnosis. MATERIALS AND METHODS: Five cases were confirmed by this technique as sphincter of Oddi dysfunction for last 13 months. All patients were female and age range was 53 to 75 years old. All patients were suffered from intermittent and recurrent biliary type pain. RESULTS: ERCP showed five common findings. The common bile duct was dilated over 12ram in all patients. Different from recurrent pyogenic cholangiohepatitis, intrahepatic ducts were proportionally dilated as extrahepatic ducts, in four patients and they branched normally and ductal wall was smooth. Transient or persistent meniscus sign was observed in four patients. All patients showed delayed emptying of contrast media from the common bile duct into the duodenum. Following IV injection of cholecystokinin, persistent meniscus disappeared and contrast media inflowed into the duodenum. CONCLUSION: Identification of all or some characteristic cholangiographic findings may eliminate a cumbersome and painful biliary manometric test for the diagnosis of sphincter of Oddi dysfunction.

PURPOSE: For the correction of ptosis with very poor levator function, frontalis sling operation with various materials has been used. The purpose of this study was to evaluate the effect of the modified Crawford technique using preserved fascia lata. METHODS: The photographs and charts of 46 patients who underwent frontalis sling operation using preserved fascia lata from June 2001 to February 2004 at our hospital were retrospectively reviewed. The eyelid crease approach was used with the suturing of the sling material directly to the tarsus. RESULTS: The patients were 27 males and 19 females. There were 20 (44%) unilateral cases and 26 (56%) bilateral cases. The age of the patients ranged from 1 to 65 years at the time of surgery, with an average age of 8.3 years. The success rate was 93% (43/46 patients) for a mean postoperative follow-up of 9 months (range 4~26 months). The complications consisted of one case of overcorrection and 2 cases of undercorrection. Knot exposure occurred in 2 cases. CONCLUSIONS: The modified Crawford technique using preserved fascia lata appears to be an effective treatment for severe ptosis. The lid crease formation provides good cosmetic results and the direct suturing of the preserved fascia lata to the tarsus prevents its migration.
