Background and Objective: Percutaneous ethanol injection therapy has been used in the treatment of the benign thyroid diseases. Although the reported side-effects of the therapy was mild and transient, some side-effects including local or radiating pain are troublesome to the patients. Radioactive iodine-131($Ra-^{131}I$) also has been effectively and safely used for management of the benign thyroid diseases. So we developed the percutaneous intranodular injection therapy of $Ra-^{131}I$ as an alternative of percutaneous ethanol injection therapy. Materials and Methods: From December 1998 to October 1999, we treated 29 outpatients (25 women and 4 men, mean age: $47{\pm}12$ years). Inclusion criteria were follows; age >30 years, cytologically benign, with normal thyroid function, cold nodule on thyroid scintigram, solid or mixed natured nodules in sonographical evaluation. Nodular volume was estimated by sonography according to the ellipsoid formula. $Ra-^{131}I$(0.1mCi/ml) was administered in a single dose injection. Follow-up studies every 3 months consisted of full history, thyroid function test, and sonography. We determined the therapeutic response is effective if the volume reduction of the nodule occurred above 30%. Results: After at least 3 months follow-up, 11 patients showed effective response, 12 patients showed minimal or unchanged response and 6 patients showed progression. Although side-effects such as injection pain, febrile reaction, and hormonal changes were absent, an infectious complication in injection site was developed from 1 case. Conclusion: Although we need a more prolonged follow-up to evaluate the delayed sequelae, we can suggest that percutaneous intranodular injection therapy of $Ra-^{131}I$ may be an attractive non-surgical treatment in selected cases of benign thyroid nodules.

Purpose: To analyze the postoperative functional and radiographic follow-up results in patients who underwent percutaneous radiofrequency ablation therapy after the diagnosis of osteoid osteoma. Materials and Methods: Seven patients, who were clinically and radiographically diagnosed with osteoid osteoma from July 1999 to January 2001, and received percutaneous radiofrequency ablation therapy. The average follow-up period was 15.5 months(range, 8~25 months). For the diagnosis and accurate localization of the lesion, simple radiography, computed tomography and magnetic resonance imaging(MRI) were performed preoperatively. Simple radiographs and MRI were taken periodically for the follow-up studies. Results: In all 7 patients, symptoms completely disappeared within 3 days after the operation. The average period of hospitalization was 2.4 days, excluding 1 patient who needed an additional burn treatment. The average postoperative night and day pain scores were 1.8 and 1.3, respectively. The average vocational and recreational activity scores were 1 and 0.6, respectively. Conclusions: Satisfactory functional results were obtained with percutaneous radiofrequency ablation therapy for the elimination of osteoid osteoma. Compared to conventional treatment, the advantages of this therapy were short hospitalization period, no internal fixation and bone graft for preventing fracture, and no limitation of joint motion by long fixation period.

Surgical treatment for afferent loop syndrome (ALS) in patients with recurrent gastric cancer is usually not feasible because of the recurrent tumor mass at the anastomosis site and/or extensive carcinomatosis resulting in bowel loop fixation. Furthermore, ALS usually makes oral intake impossible, resulting in a rapid deterioration in general condition. In this situation, gastroscopic stenting at the anastomotic site and/or percutaneous external drainage may be a more feasible alternative for palliation. We herein report a recurrent gastric cancer whose ALS was successfully treated with internal and external drainage procedures.

Minimally invasive cryoablation is often considered for lung tumor patients with high surgical risk or inoperable metastatic lung tumors. Cryoablation is a type of thermal percutaneous ablation in which argon and helium gases are delivered via a cryoprobe to induce tissue freezing and necrosis. We report the case of a 23-year-old woman who had suffered from multiple pulmonary endometriosis with frequent intermittent hemoptysis during menstruation for 6 years prior to her visit. She was treated with cryoablation at our hospital, and since her treatment, she has been doing well with no hemoptysis for at least 6 months. Although endometriosis is a benign lung disease, cryoablation is an ideal and effective treatment option for patients with multiple endometriosis.

Urinary tract infection (UTI) is most commonly diagnosed bacterial infection in febrile infants. Renal abscess is a very rare complication of UTI in children. Early diagnosis and treatment with appropriate antibiotics are important because renal scar correlates positively with the time of treatment. Renal ultrasonography and abdominal computerized tomography facilitates an earlier diagnosis and is also useful in establishing percutaneous drainage. Extended broad spectrum antibiotics therapy alone can be effective in most types of renal abscesses in infant, but some antibiotics-resistant cases need surgical drainage or nephrectomy. We report a case of a infant UTI, that progressed to renal abscess despite early antibiotic treatment and was treated with US guided percutaneous needle aspiration.

Purpose: The purpose of this study was to explore the differences of health locus of control and treatment compliance according to general characteristics and severity in acute coronary syndrome(ACS) patients after percutaneous coronary intervention. Methods: This descriptive study was conducted with a convenient sample of 103 ACS patients. The dependent variables were measured by the scales for the Multidimensional Health Locus of Control and the Treatment Compliance. The collected data were analyzed by the Fisher's exact test, Chi-square and t-tests, and ANOVA using the SPSS program. Results: Pre-interventional severity was significantly different between men and women. In terms of internal health locus of control, there was a significant difference according to gender, educational status, economic status, and severity. The level of medication compliance was the lowest among the sub-scales of treatment compliance. Conclusion: These findings suggest that clinical nurses should evaluate the general characteristics and severity of the patients with ACS for providing tailored nursing interventions.

When medical therapy fail to relieve pain at tolerable level for patients confirmed with trigeminal neuralgia, presence of mass lesion excluded, surgery is indicated. Innumerable surgical strategies have been attempted for the treatment of trigeminal neuralgia but only four have proven appropriate: (1)stereotactic radiofrequency gasserian ganglionotomy, (2) percutaneous glycerol gangliolysis, (3) percutaneous microcompression, (4) microvascular decompression. Radiofrequency thermocoagulation of the gasserian ganglion stems from the efforts of Sweet. This technique is the surgical treatment of choice around the world for surgical treatment for trigeminal neuralgia. Since 1986, over 14,000 cases have been reported utilizing this technique. To improve the treatment method further, an electrode with a flexible curved tip has been developed for easier and more precise electrode placement and lesion production during the thermocoagulation of gasserian ganglion. This operation was performed recently on three patients at Hallym University Hospital. using a curved tip electrode. Complete relief of pain was achieved for all patient. However, some complications were noted.

Sacral insufficiency fracture is a debilitating injury not easily found in general radiologic examinations and is rarely diagnosed, since its symptoms are obscure. It is known to frequently occur in patients with osteoporosis, but the treatment has not yet been established and various kinds of treatment methods are being attempted. Sacroplasty is sometimes performed by applying percutaneous vertebroplasty which is known to be a less invasive treatment. Since the course of diagnosis of sacral insufficiency fracture is difficult and clear guidelines for treatments have not yet been established, many spine surgeons fail to diagnose patients or speculate on treatment methods. We report our experience in diagnosing a sacral insufficiency fracture in a 54-year-old healthy female patient using MRI and treating her with sacroplasty. From a therapeutic point of view, we then cover the usefulness, effects and characteristics relating to the complications of sacroplasty, along with literature review.

Objective : The aim of this prospective study was to evaluate the efficacy of bone cement-augmented percutaneous short segment fixation for treating Kummell's disease accompanied by severe osteoporosis. Methods : From 2009 to 2013, ten patients with single-level Kummell's disease accompanied by severe osteoporosis were enrolled in this study. After postural reduction for 1-2 days, bone cement-augmented percutaneous short segment fixation was performed at one level above, one level below, and at the collapsed vertebra. Clinical results, radiological parameters, and related complications were assessed preoperatively and at 1 month and 12 months after surgery. Results : Prior to surgery, the mean pain score on the visual analogue scale was $8.5{\pm}1.5$. One month after the procedure, this score improved to $2.2{\pm}2.0$ and the improvement was maintained at 12 months after surgery. The mean preoperative vertebral height loss was $48.2{\pm}10.5%$, and the surgical procedure reduced this loss to $22.5{\pm}12.4%$. In spite of some recurrent height loss, significant improvement was achieved at 12 months after surgery compared to preoperative values. The kyphotic angle improved significantly from $22.4{\pm}4.9^{\circ}$ before the procedure to $10.1{\pm}3.8^{\circ}$ after surgery and the improved angle was maintained at 12 months after surgery despite a slight correction loss. No patient sustained adjacent fractures after bone cement-augmented percutaneous short segment fixation during the follow-up period. Asymptomatic cement leakage into the paravertebral area was observed in one patient, but no major complications were seen. Conclusion : Bone cement-augmented percutaneous short segment fixation can be an effective and safe procedure for Kummell's disease.
