Inflammatory myofibroblastic tumor (IMT) is a rare reactive lesion characterized by the feature of myofibroblasts and a mixed inflammatory infiltrate that rarely undergoes malignant transformation. Extrapulmonary IMTs in children have been described involving the mesentery, omentum, retroperitoneum, abdominal soft tissues, liver, bladder, mediastinum, head and neck, extremity, appendix, and kidney. Medical records of children treated with abdominal IMT between 1985 and 2005 were reviewed retrospectively. Seven children were treated for IMT with the mean age of 3 y 2 m (range, 1 y 1 m to 14 y). Tumors were located in transverse mesocolon (n=2), omentum (n=1), porta hepatis (n=2), complex site (antrum, duodenum, common bile duct, porta hepatis) (n=2). The symptoms included abdominal mass, fever, jaundice, abdominal pain and anemia. The masses were excised totally in transverse mesocolon, omentum IMT and there is no evidence of recurrence (follow-up periods: 6 y 8 m, 8 y 9 m, 4 y 10 m). In porta hepatis IMT, liver transplantations were performed and there is no evidence of recurrence (follow period: 6 y 8 m, 8 y 7 m). In one case of complex site IMT, partial excision of mass was performed and he still survived with no change of the residual tumor during follow-up period. The other one of complex site IMT denied further treatment after the biopsy. In conclusion, complete surgical excision including liver transplantation and close follow-up are mandatory for the abdominal IMT in child.

Spasmodic dysphonia is a disease presumed to be a form of focal laryngeal dystonia. The widely used first-line treatment is botulinum toxin injection to the thyroarytenoid muscles. In spite of the effectiveness and safety of this method, it has a temporary effect that lasts only several months, resulting the patients' symptom fluctuating, called 'Botox rollercoaster.' Some surgical techniques had tried, but they had shown several limitations including high rate of recurrence. We tried thyroarytenoid myectomy with selective recurrent laryngeal nerve section in a patient with intractable spasmodic dysphonia. This procedure is an alternative treatment of spasmodic dysphonia to prevent recurrence and improve symptoms. During five years of follow-up, she has shown steady quality voice without any complication. To the best of our knowledgement, this is the longest follow-up case of this operation in South Korea.

Objective : This study assessed the effect of a combination of Korean medicine on a thyroid papillary cancer patient who was diagnosed with local lymph node metastasis after thyroidectomy and lymph node dissection but did not want surgery. Methods : Gami-Palmultang administration and moxibustion(large Bmoxa cautery) were performed for six years. Treatment outcomes were evaluated with Brief Fatigue Inventory (BFI), Numerical Rating Scale (NRS), Insomnia Severity Index (ISI), Functional Assessment of Cancer Therapy-General (FACT-G), blood test/ CT imaging results, and patient's statements. Results : After the treatment, all symptoms have been alleviated, the quality of life has increased, and it has been maintained without further metastasis of tumors for six years. Conclusion : Korean medicine treatment along with active observation can be an alternative to patients who do not want surgical treatment after recurrence of local lymph nodes in thyroid papillary cancer, and can have positive results in improving the quality of life.

Background: The aim of this study was to evaluate the clinical efficacy of a modified surgical procedure for the treatment of varicose veins. Methods: This retrospective analysis was conducted on lower extremities with symptomatic great saphenous vein (GSV) incompetence that underwent stripping from the groin to the knee, with preservation of the superficial epigastric vein (SEV), between January 2015 and April 2022. Follow-up assessments were performed using Doppler ultrasound, Venous Clinical Severity Score (VCSS), and the Aberdeen Varicose Vein Questionnaire (AVVQ) at 6 and 12 months after surgery. Results: The study included 179 limbs from 120 patients (47 men and 73 women). The mean patient age was 56.5 years (range, 20-78 years), and the distribution of preoperative Clinical-Etiology-Anatomy-Pathophysiology clinical classes was 8% C0-C1, 88% C2, and 4% C3-C6. The preoperative diameter of the saphenofemoral confluence averaged 6.9 mm (range, 2.7-15.8 mm). After a mean postoperative follow-up period of 24 months, evidence of neovascularization around the stump of the saphenofemoral junction (SFJ) was observed in 2 limbs (1.1%). Additionally, varicose vein recurrence was found in 1 limb (0.6%) and was associated with an incompetent thigh perforator. At postoperative follow-up, both VCSS and AVVQ scores were significantly lower than the preoperative scores. Conclusion: Modified surgical treatment of GSV incompetence, involving preservation of the SEV and stripping of a short segment up to the knee, demonstrated favorable clinical results in terms of postoperative complication rate, neovascularization rate around the SFJ stump, varicose vein recurrence rate, and improvement in lower extremity symptoms.

Background & Objectives: Frameless fractionated stereotactic radiotherapy(FFSRT) is a modification of stereotactic radiosurgery(SRS) with radiobiologic advantage of fractionation without losing mechanical accuracy of SRS. Local recurrence of head and neck cancer at or near skull base benefit from reirradiation. Main barrier to successful palliation is dose limitation secondary to normal tissue tolerance. We try to evaluate the efficacy and safety of FFSRT as a new modality of reirradaton in these challenging patients. Materials & Methods: Seven patients with recurrent head & neck cancer involving at or near skull base received FFSRT from September 1995 to November 1997. Six patients with nasopharyngeal cancer had received induction chemotherapy and curative radiation therapy. One patient with maxillary sinus cancer had received total maxillectomy and postoperative radiation therapy as a initial treatment. Follow-up ranged from 11 to 32 months with median of 24 months. Three of 7 patients received hyperfractionated radiation therapy(1.1-1.2Gy/fraction, bid, total 19.8-24Gy) just before FFSRT. All patients received FFSRT(3-5Gy/fraction, total 15-30Gy/5-10fractions). Chemotherapy(cis-platin $100mg/m^2$) were given concurrently with FFSRT in four patients. Second course of FFSRT were given in 4 patients with progression or recurrence after initial FFSRT. Because IF(irregularity factor; ratio of surface area of target to the surface area of sphere with same volume as a target) is too big to use conventional stereotactic RT using multiple arc method for protection of radiation damage to critical normal tissue, all patients received FFSRT with conformal method using irregular static ports. Results: Five of 7 patients showed complete remission in follow-up CT &/or MRI. Three of these five patients who developed marginal, in-field, and out-field recurrences, respectively. Another one of complete responders has been dead of G-I bleeding without evidence of local recurrence. One partial responder who showed progressive disease 15 months after initial FFSRT has received additional FFSRT, and then he is well-being with symptomatic improvement. One minmal responder who showed progression of locoregional disease 9 months after $1^{st}$ FFSRT has received 2nd FFSRT, and then he is alive with stable disease. Five of 7 case had showed direct invasion to skull base and had complaint headache and various symptoms of cranial nerve involvement. Four of these five case showed improvement of neurologic symptoms after FFSRT. No significant neurologic complicaltion related to FFSRT was observed during follow-up periods. Tumor volumes were ranged from 3.9 to 50.7 cc and surface area ranged from 16.1 to $114.9cm^2$. IF ranged from 1.21 to 1.74. The average ratio of volume of prescription isodose shell to target volume was 1.02 that indicated the improvement of target coverage and dose distribution with FFSRT with conformal method compared to target coverage with FFSRT with multiple arc method. Conclusion: Our initial experience suggests that FFSRT with conformal method was relatively effective and safe modality in the treatment of recurrent head and neck cancer involving at or near skull base. Treatment benefit included good palliation of symptoms and reasonable radiographic response. However, more experience and additional follow-up are needed to better assess its ultimate role in treating these challenging patients.

Background: Gestational trophoblastic neoplasia (GTN) is a spectrum of disease with abnormal trophoblastic proliferation. Treatment is based on FIGO stage and WHO risk factor scores. Patients whose score is 12 or more are considered as at extremely high risk with a high likelihood of resistance to first line treatment. Optimal therapy is therefore controversial. Objective: This study was conducted in order to summarize the regimen used for extremely high risk or resistant GTN patients in our institution the in past 10 years. Materials and Methods: All the charts of GTN patients classified as extremely high risk, recurrent or resistant during 1 January 2002 to 31 December 2011 were reviewed. Criteria for diagnosis of GTN were also assessed to confirm the diagnosis. FIGO stage and WHO risk prognostic score were also re-calculated to ensure the accuracy of the information. Patient characteristics were reviewed in the aspects of age, weight, height, BMI, presenting symptoms, metastatic area, lesions, FIGO stage, WHO risk factor score, serum hCG level, treatment regimen, adjuvant treatments, side effects and response to treatment, including disease free survival. Results: Eight patients meeting the criteria of extremely high risk or resistant GTN were included in this review. Mean age was 33.6 years (SD=13.5, range 17-53). Of the total, 3 were stage III (37.5%) and 5 were stage IV (62.5%). Mean duration from previous pregnancies to GTN was 17.6 months (SD 9.9). Mean serum hCG level was 864,589 mIU/ml (SD 98,151). Presenting symptoms of the patients were various such as hemoptysis, abdominal pain, headache, heavy vaginal bleeding and stroke. The most commonly used first line chemotherapeutic regimen in our institution was the VAC regimen which was given to 4 of 8 patients in this study. The most common second line chemotherapy was EMACO. Adjuvant radiation was given to most of the patients who had brain metastasis. Most of the patients have to delay chemotherapy for 1-2 weeks due to grade 2-3 leukopenia and require G-CSF to rescue from neutropenia. Five form 8 patients were still survived. Mean of disease free survival was 20.4 months. Two patients died of the disease, while another one patient died from sepsis of pressure sore wound. None of surviving patients developed recurrence of disease after complete treatment. Conclusions: In extremely high risk GTN patients, main treatment is multi-agent chemotherapy. In our institution, we usually use VAC as a first line treatment of high risk GTN, but since resistance is quite common, this may not suitable for extremely high risk GTN patients. The most commonly used second line multi-agent chemotherapy in our institution is EMA-CO. Adjuvant brain radiation was administered to most of the patients with brain metastasis in our institution. The survival rate is comparable to previous reviews. Our treatment demonstrated differences from other institutions but the survival is comparable. The limitation of this review is the number of cases is small due to rarity of the disease. Further trials or multicenter analyses may be considered.

Clinical studies were made on 79 cases with thalamic hemorrhage diagnosed by computed tomographic scan and only localized on the thalamic area, were admitted to the Kyung San University Taegu Oriental Medical Hospital from August 1990 to March 1994. The age and sex distribution, sites of hematoma, recurrence rate, incidence of hypertension, inducing factor, prodromal syndroms, symptoms and neurologic signs on admission, relationship between the hospital course and many factors affecting the prognosis such as age, side of hematoma, level of consciousness, volume of the hematoma. ventricular hemorrhage were analysed. The results were summarized as follows; 1. The most prevalent age group was above 60 years of age with 50-59 years, 70-79 years, 40-49 years and 80-89 years of age in the order of frequency. Male to female ratio was 1:1.55. 2. The ratio of left hematoma to the right was 1.32:1. The recurrence rate of cerebrovascular accident was 17.7% 3. The incidence of hypertension was 69.6% and inducing factors of thalamic hemorrhage in the order of frequency were physical work(29.1%), drinking or eating(13.9%), walking(12.7%) and rest(12.7%), The prodromal syndroms were numbness of extremities(5.1%), headache(2.5%), fatigue(2.5%), dizziness(1.3%), insomnia(1.3%), but prodromal syndrom was not found in 89.9% of thalamic hemorrhage. 4. The symptoms and neurologic signs on admission in the order of frequency were motor disturbance(98.7%), dysarthria(82.3%), positive Babinski sign(78.5%), headache(69.6%), dizziness(62.0%). hemisensory deficit(48.1%). nausea or vomiting(39.2%), absent or sluggish light reflex(35.4%), changes of consciousness (35.4%), dysphagia (20.3%), voiding difficulty.(13.9%), facial palsy(6.3%), aphasia(3.8%), seizure(38%), 6th N. palsy(3.8%) and small pupil(1.3%). 5. The rate of improvement was found almost equally in the 4th, 5th and 6th decades, but it was shown with dramatic decrease in the over 7th decades. The hospital course had no relationship with the side of hematoma but the level of consciousness had influence upon the prognosis. 6, The small hematoma had better outcome than large in the volume of hematoma under 15cc, but volume of the hematoma had no influence upon the prognosis because the rate of improvement was 75.0% in the volume of hematoma over 15cc. The hospital course had no relationship with ventricular hemorrhage.

Purpose: Endoscopic transnasal correction of the blowout fractures has many advantages over other techniques. But after removal of packing material, there were some patients with recurrence of preoperative symptoms. Authors tried to make a quantitative anterograde analysis of orbital volume change over whole perioperative period which might be related with recurrence of preoperative symptoms. Methods: 10 patients with pure medial wall fracture(Group I) and 10 patients with medial wall fracture combined with fracture of orbital floor(Group II) were selected to evaluate the final orbital volume change, who took 3 CT scans, pre-, postoperative and 4 months after packing removal. By multiplying cross - section area of orbit in coronal view with section thickness, orbital volume were calculated. Then, mean orbital volume increment after trauma, mean orbital volume decrement after endoscopic correction and volume increment after packing removal were found out. And we tried to find correlations between type of fracture, initial correction rate and final correction rate. Results: The mean orbital volume increment of the fractured orbits were 7.23% in group I and 13.69% in group II. After endoscopic surgery, mean orbital volume decrement were 11.0% in group I and 12.46% in group II. Mean volume increment after packing removal showed 3.10% in group I and 6.50% in group II. The initial correction rate(%) showed linear correlation with final correction rate(%) after packing removal. And there were negative linear correlation between increment percentage of orbital volume by fracture and final correction rate(%). Conclusion: Orbital volume was proved to be increasing after removal of packing or foley catheter and it was dependent upon type of fracture. Overcorrection should be done to improve the final result of orbital blowout fracture especially when there are severe fracture is present.

배경: 다한증 환자에서 흉부교감신경절단술은 효과적인 치료방법으로, 수술직후에는 만족도가 높으나 시간이 지남에 따라 재발 및 보상성 발한으로 인해 만족도가 떨어지는 경향이 있다. 재발 및 보상성 발한을 최소화하기 위해 신경절제를 위한 다양한 방법이 제시되고 있다. 이에 흉부교감신경의 절단범위에 따른 증상 및 만족도, 재발, 보상성 발한을 비교 평가하였다. 대상 및 방법: 1999년 1월부터 2007년 7월까지 수부 다한증으로 흉부 교감신경절단술을 시행한 180명의 환자 중 술 후 추적이 가능했던 111명을 대상으로 하였다 제3번 늑골 상연에서 교감신경절을 절단한 39예(R3)와 제4번 늑골상연에서 교감신경절을 절단한 72예(R4)로 나누어서 술 후 초기 및 중기 만족도, 보상성 발한, 재발의 정도를 비교하였다. 결과: 두 군간의 연령에 있어서는 차이가 있었으나 성별에 있어서는 차이가 없었다. 초기의 만족도(R3, R4)는 각각 94.9%, 98.7%로 차이가 없었고, 중기 만족도 또한 84.6%, 87.5%로 차이가 없었다. 일상 생활에 불편함을 초래하는 중증도 이상의 보상성 발한은 R3에서 23.1%, R4에서 9.7%로 유의한 차이를 보였다(p=0.020). 재발되어 재수슬한 경우는 각각 5.1%, 4.2%로 유의한 차이를 보이지는 않았다. 결론: 수부다한증의 치료에 있어 교감신경절단술 시 R4가 R3에 비해 초기 및 중기 만족도 및 재발에 있어서는 차이가 없으나, 술 후 보상성 발한이 보다 적은 것으로 보인다.
