Sacral pressure sores have been treated by a variety of surgical methods. complete treatment needs wide excision and coverage with healthy tissue which has constant and sufficient blood supply. Use of gluteus maximus muscle flap with or without overlying skin is a revolutionary method because of the reliability of blood supply. However, it is technically a little bit complicated, and future reconstruction for recurrent decubitus is especially limited in paraplegic patients. The development of gluteal perforator-based flap with para-sacral perforator introduce a new treatment modality for the sacral pressure sores. Total 10 cases of sacral pressure sores were treated with gluteal perforator-based flap. There were minimal postoperative complications except wound dehiscence in one case. This flap has a many advantage of no transection or sacrifice of the gluteus maximus muscle, elevation time for the flap is short, reliable blood flow of the perforator, large rotation arc and no post-operative hindrance to walking in patients who are not paraplegic. The disadvantages of this perforator-based flaps are the anatomical variation in the location of perforators and the need for technically careful dissection.

A 43 years old woman had suffered from a lower back pain for 2 months. She experienced pain aggravation after spinal manipulative therapy that was practiced by non-licentiate. Physical examination showed tenderness on L1 and L2 spinous processes. Radionuclide bone scan with 99mTc-MDP showed increased radioactivity of L1, L2 vertebral bodies. The MRI finding showed low signal intensity of L1 and L2 vertebral bodies in T1-weighted image and high signal intensity in T2-weighted image. Needle biopsy finding showed fibrosis and inflammatory cell invasion of bone marrow. We concluded that she had tuberculous spondylitis and non-detection or negligent treatment of a preexisting disease contributed to aggravation of her symptoms. We report one case of tuberculous spondylitis aggravated by spinal manipulative therapy with review of literatures.

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.

Checkrein deformity is characterized by the dynamic status of the hallux, in which flexion deformity is aggravated by ankle dorsiflexion and relieved by ankle plantarflexion. In most cases, a checkrein deformity occurs secondary to trauma or following surgery.It has been suggested that the flexor hallucis longus tendon tethers or entraps scar tissue or fracture sites. Improvement with conservative treatment is difficult once the deformity has already become entrenched, and surgical management is usually required in severe cases. Various surgical options are available for the correction of checkrein deformities. It includes a simple release of adhesion at the fracture site; lengthening of the flexor hallucis longus by Z-plasty at the fracture site combined with the release of adhesion; lengthening of the flexor hallucis longus by Z-plasty at the midfoot, retromalleolar, or tarsal tunnel area; and flexor hallucis longus tenotomy with interphalangeal arthrodesis for recurrent cases. This review aimed to summarize the overall etiology, relevant anatomy, diagnosis, and treatment of checkrein deformities described in the literature.

PURPOSE: This study was performed in order to compare unenhanced CT with diffusion-weighted, T2-weight-ed,and fast FLAIR MR imaging in the detection of hyperacute cerebral ischema induced in a dog and to deter-mine whichmodality first detected cerebral ischemia. MATERIALS AND METHODS: Experimental cerebral infarction was induced bythe occlusion of intracerebral arter-ies using embolic materials (polyvinyl-alcohol, 300 -6 00 micro) introducedthrough a microcatheter into the internal carotid artery of five dogs weighing 12 -20 kg. Serial CT and MR imageswere obtained at one hour intervals from one to five hours after occlusion, and were analyzed independently by tworadiologists. We assessed changes in attenuation, as seen on unenhanced CT and the signal intensity of the lesionon each MR image, and measured the contrast-to-noise ratio (CNR) of the lesions. RESULTS: Ischemic lesions weredetected on unenhanced CT 1 -3 hours after occlusion of cerebral arteries. In all dogs, the lesions were detectedearliest on diffusion-weighted images obtained at 1 hour. They were detect-ed on T2-weighted images at 3 -5 hoursand on fast FLAIR images of 2 -5 hours. The CNR of ischemic lesions increased gradually during the 5-hour period.It was highest on diffusion-weighted images, while on unen-hanced CT, T2-weighted, and fast FLAIR images it wassimilar. CONCLUSION: Hyperacute ischemic lesions were detected earliest on diffusion-weighted images, and earlieron unenhanced CT than on fast FLAIR or T2-weighted MR image.

Four hundred and eighty two hepatic resections were performed from June 1989. to May 1995. There were 328 normal livers, 120 cirrhotic livers, and 34 jaundice livers. The indications for hepatic resection were intrahepatic duct stone in 235, hepatocellular carcinoma in 137, peripheral cholangiocarcinoma in 24, Klatskin tumor in 38, metastatic liver cancer in 17, gallbladder cancer in 14 and other benign disease in 17. In the aspect of operative procedures, there were 84 right lobectomies, 27 extended right lobectomies, 16 right trisegmentectomies, 1 left trisegmentectomy, 30 extended left lobectomies, 6 central bisegmentectomies, 133 left lobectomies, and 185 other minor resections. Major postoperative complications(13.7%) were intraabdominal abscess and biliary leak(7.1%), hemorrhage(3.5%), hepatic failure(1.2%), pneumonia(1.7%), and liver infarct(0.2%). The factors affecting the major complications were intraoperative transfusion, operation time, resection volume, cirrhosis, and jaundice. Eleven of 482 patients died within 30 days of the operation, with an operative mortality rate of 2.3%. None of normal liver patients died postoperatively. Seven patients of the eleven deaths had cirrhotic liver(mortality rate : 5.8%). Four patients of the eleven deaths had jaundice liver(mortality rate: 11.8%). The factors affecting the operative mortality were intraoperative transfusion, operation time, cirrhosis, and jaundice.

Arterial restenosis frequently develops after open or endovascular surgery due to intimal hyperplasia. Since tissue transglutaminase (TG2) is known to involve in fibrosis, wound healing, and extracellular matrix remodeling, we examined the role of TG2 in the process of intimal hyperplasia using TG2-null mice. The neointimal formation was compared between TG2-null and wild-type (C57BL/6) mice by two different injury models; carotid ligation and carotid loop injury. In ligation model, there was no difference in intimal thickness between two groups. In loop injury model, intimal hyperplasia developed in both groups and the intimal/medial area ratio was significantly reduced in TG2-null mice (P = 0.007). TG2 was intensely stained in neointimal cells in 2 weeks. In situ activity of TG2 in the injured arteries steadily increased until 4 weeks compared to uninjured arteries. Taken together, intimal hyperplasia was significantly reduced in TG2-null mice, indicating that TG2 has an important role in the development of intimal hyperplasia. This suggests that TG2 may be a novel target to prevent the arterial restenosis after vascular surgery.

Colonoscopy is a safe and standard procedure for diagnosis and therapy of colonic disorders. Iatrogenic colonic perforation during diagnostic colonoscopy, a rare abdominal emergency, has an 0.3~0.8% incidence rate. The choice of treatment for this complication remains controversial. Prompt operative intervention is preferred to minimize morbidity and mortality. However, operative intervention is invasive and needs a long-term recovery period. Conservative treatment is less invasive but can lead to more extensive surgery in case of treatment failure. Very important point on the treatment of iatrogenic perforation of the colon during diagnostic colonoscopy is to avoid the leaking of intestinal contents into the intraperitoneal cavity. We report here a case in which an iatrogenic perforation of the colon during diagnostic colonoscopy was successfully treated by endoscopic clip therapy.

Klinefelter's syndrome (KFS) is a gonosomal aberration disease that occurs in males, and is characterized by 47, XXY karyotype, hypogonadism and a lack of secondary sexual characteristics. A potential link between this hormonally deficient syndrome and autoimmune disease, particularly systemic lupus erythematosus (SLE), has been reported. On the other hand, KFS is rarely reported to be accompanied by rheumatoid arthritis (RA), and there are no Korean cases reported. We report the first Korean case of a KFS patient with sero-positive RA and discuss the role of the pathogenesis of RA with KFS.
