Objective: To investigate the clinical effects of whole brain radiotherapy concomitant with targeted therapy for brain metastasis in non-small cell lung cancer (NSCLC) patients with chemotherapy failure. Materials and Methods: Of the 157 NSCLC patients with chemotherapy failure followed by brain metastasis admitted in our hospital from January 2009 to August 2012, the combination group (65 cases) were treated with EGFR-TKI combined with whole brain radiotherapy while the radiotherapy group (92 cases) were given whole brain radiotherapy only. Short-term effects were evaluated based on the increased MRI in brain 1 month after whole brain radiotherapy. Intracranial hypertension responses, hematological toxicity reactions and clinical effects of both groups were observed. Results: There were more adverse reactions in the combination group than in radiotherapy group, but no significant differences were observed between the two groups in response rate (RR) and disease control rate (DCR) (P>0.05). Medium progression free survival (PFS), medium overall survival (OS) and 1-year survival rate in combination group were 6.0 months, 10.6 months and 42.3%, while in the radiotherapy group they were 3.4 months, 7.7 months and 28.0%, respectively, which indicated that there were significant differences in PFS and OS between the two groups (P<0.05). Additionally, RPA grading of each factor in the combination group was a risk factor closely related with survival, with medium PFS in EGFR and KRAS mutation patients being 8.2 months and 11.2 months, and OS being 3.6 months and 6.3 months, respectively. Conclusions: Whole brain radiotherapy concomitant with target therapy is favorable for adverse reaction tolerance and clinical effects, being superior in treating brain metastasis in NSCLC patients with chemotherapy failure and thus deserves to be widely applied in the clinic.

Objective : This is prospective study of clinical outcomes of percutaneous plasma disc coagulation Therapy (PDCT) in patients with herniated lumbar disc disease (HLD) to evaluate the safety and efficacy in its clinical application and usefulness as a reliable alternative to microscopic discectomy. Methods : Forty-six patients were enrolled in this study from April 2006 to June 2010. All patients had one-level HLD. Disc degeneration was graded on routine T2-weighted magnetic resonance Image (MRI) using the Pfirrmann's grading system and all index levels were grade 3 and grade 4. Indications for surgery were radiculopathy caused by disc protrusion with soft consistency. MRI was done at one month after the procedure in all patients to check post-PDCT change. The clinical outcomes were evaluated using Visual Analog Scales (VAS) score and MacNab's criteria. Results : This study was approved by the Institutional Review Board of our institution. The age of the study population ranged from 16 to 59 years with a mean age of 37.2 years. There were 29 males and 17 females in this study. The mean period of clinical follow-up was 21 months. The average preoperative VAS score for radiculopathy was $7.4{\pm}1.4$, while the final follow-up VAS score was $1.4{\pm}0.7$ (p<0.001). In MacNab's criteria, 41 patients (89.1%) had achieved favorable improvement (excellent and good) until later follow-up. There were one patient from infection and two patients who needed to convert to open discectomy. Conclusion : PDCT is a safe and efficient treatment modality in a selective patient with HLD.

Objectives The purpose of this study was to review and evaluate the clinical evidence of the efficacy and safety of treatment based on Sasang constitutional medicine (SCM) for post-stroke patients by systematic review and meta-analysis. Methods Randomized controlled trials (RCTs), published in 10 electronic databases up to December 2020, were searched. For the included studies, Cochrane's risk of bias assessment was performed to analyze the methodological quality. The strength of evidence was evaluated using the grading of recommendations assessment, development, and evaluation system based on the results of analyses. All review processes were performed by two independent researchers. Results Five RCTs were finally included. All included RCTs were conducted for one month on post-stroke patients in 60-80s, four studies on Tae-Eum patients and one study on So-Yang patients. Four types of constitution-specific herbal medicine (Chungpyesagan-tang, Cheongsimsanyak-tang, Yeoldahanso-tang, and Yangkyuksanhwa-tang) and constitution-specific acupuncture therapy were identified as interventions. More than half of the included studies were evaluated as low quality due to the high-risk of bias in selection, performance, and detection. The combination of constitution-specific herbal medicine, acupuncture, and conventional treatment was more effective in improving the patients' motor impairment, dysphagia, aphasia, and depression than conventional treatment alone. No serious adverse events by SCM treatment were reported. Conclusions SCM treatment may improve the sequelae of post-stroke patients safely in combination with conventional treatment. Since the quality of clinical evidence included in this study was low, higher quality clinical evidence obtained in well-designed clinical studies will be needed.

Objective : By conducing a review of clinical outcomes for patients with aneurysm treated using current microneurosurgical techniques and intensive care unit management, we speculated that grading systems based only on clinical condition or CT finding after admission failed to provide a significant stratification of outcome between individual grades of patients, because these systems did not include the factor for postoperative vasospasm. We hypothesized that postoperative blood flow velocity could have a significant impact on outcome prediction for patients surgically treated for intracranial aneurysms. Methods : We conducted a analysis on patient- and lesion-specific factors that might have been associated with outcome in a series of 55 aneurysm operations performed with measurements of blood-flow velocity with transcranial Doppler ultrasonography(TCD). In the new scale(NS) score system, 1 point is assigned additionally for the case with Hunt and Hess(H-H)/World Federation of Neurological Surgeons(WFNS) Grade IV or V, Fisher Scale(FS) score 3 or 4, aneurysm size greater than 10mm, patient age older than 60 years, blood-flow velocity higher than 120cm/sec, and posterior circulation lesion. By adding the total points, a 6-point scale score(score 0-6) is obtained. Results : Age of patient, size of aneurysm, clinical condition(H-H grade and WFNS), FS score, and blood flow velocity(TCD 1day after operation) were independently and strongly associated with long-term outcome. When NS scores were applied to 55 patients with at least 6 months follow-up, the correlation of individual scores with outcome was strongly validated the retrospective findings. Conclusion : It was speculated that TCD could be used to assess postoperative vasospasm and to monitor noninvasively the patients with aneurysmal SAH. This NS score system is easy to apply, divide patients into groups with different outcome, and is comprehensive, allowing for more accurate prediction of surgical outcome.

Objective : The inter-rater reliability of the modified Knosp's classification was measured before the analysis. The clinical validity of the parasellar extension grading system was evaluated by investigating the extents of resection and complication rates among the grades in the endoscopic endonasal transsphenoidal surgery (EETS) for pituitary adenomas. Methods : From November 2008 to August 2015, of the 286 patients who underwent EETS by the senior author, 208 were pituitary adenoma cases (146 non-functioning pituitary adenomas, 10 adrenocorticotropic hormone-secreting adenomas, 31 growth hormone-secreting adenomas, 17 prolactin-secreting adenomas, and 4 thyroid-stimulating hormone-secreting adenomas; 23 microadenomas, 174 macroadenomas, and 11 giant adenomas). Two neurosurgeons and a neuroradiologist independently measured the degree of parasellar extension on the preoperative sellar MRI according to the modified Knosp's classification. Inter-rater reliability was statistically assessed by measuring the intraclass correlation coefficient. The extents of resection were evaluated by comparison of the pre- and post-operative MR images; the neurovascular complications were assessed by reviewing the patients' medical records. The extent of resection was measured in each parasellar extension grade; thereafter, their statistical differences were calculated. Results : The intraclass correlation coefficient value of reliability across the three raters amounted to 0.862. The gross total removal (GTR) rates achieved in each grade were 70.0, 69.8, 62.9, 21.4, 37.5, and 4.3% in Grades 0, 1, 2, 3A, 3B, and 4, respectively. A significant difference in the extent of resection was observed only between Grades 2 and 3A. In addition, significantly higher complication rates were observed in the groups above Grade 3A. Conclusion : Although the modified Knosp's classification system appears to be complex, its inter-rater reliability proves to be excellent. Regarding the clinical validity of the parasellar extension grading system, Grades 3A, 3B, and 4 have a negative predictive value for the GTR rate, with higher complication rates.

Purpose: The modified Broström repair (BR) technique has yielded good outcomes in patients with chronic ankle instability. This study compared clinical and radiological outcomes between two groups of patients who underwent modified BR or lateral ligament augmentation using suture tapes (ST). Materials and Methods: Seventy-seven patients (ST group [n=47], BR group [n=30]; body mass index <26.61 kg/m²; mean age, 30.7±11.0 years [range, 17~39 years]; mean follow-up, 34.0±12.0 months [range, 24~59 months]) were retrospectively reviewed between January 2014 and July 2017. The Foot and Ankle Outcome Score (FAOS), American Orthopedic Foot and Ankle Score (AOFAS), Foot and Ankle Ability Measure (FAAM), visual analogue scale (VAS) score, and Sefton grading system were used for clinical assessment. The talar tilt angle and anterior talar translation were measured using the Telos stress device (Telos GmbH, Marburg, Germany) at 150 N for radiological evaluation. Results: FAOS, AOFAS, FAAM, and VAS scores improved in both groups at final follow-up (ST, 91.1±5.2, 93±2, 88.1±4.5, 1.5±0.7 vs. BR, 91.3±5.4, 93±3, 83.3±4.8, 1.2±0.7, respectively; p=0.854, 0.971, <0.001, 0.04, respectively). According to the FAOS, mean sports activity scores for the ST and BR groups at the final follow-up were 90.3±3.2 and 76.6±4.2, respectively, reflecting superior outcomes in the ST group (p<0.001). Sefton grading revealed satisfactory functional outcomes (ST, 91.5% vs. BR, 90.0%). There was significant improvement in the talar tilt angle and anterior talar translation in both the ST and BR groups (7.6°±1.2°, 10.5±1.8 mm vs. 4.9°±1.1°, 7.9±1.5 mm, respectively; p<0.001). Conclusion: The ST group demonstrated comparable clinical but better improvement in mechanical stability and FAOS sports scores than the BR group.

목적 : IgA 신병증은 다양한 임상 소견을 보일 수 있으며 초기에는 대부분 예후가 양호한 것으로 알려졌었으나 현재는 발병 20년후 20-30%가 말기 신부전증을 초래한다고 알려져 있다. IgA 신병증의 예후를 예측하기 위한 여러 조사에서 발병 초기의 심한 단백뇨, 고혈압, 조직 병리학 상의 심한 변화 등이 있을 경우 예후가 나쁘다고 하였다. 1996년 Yagame등은 IgA 신병증에서 새로운 조직 병리학적 분류를 하였고 WHO 분류 방법이 사구체 병변을 중심으로 한데 비해 세뇨관과 간질의 변화까지 포함하고 있어 이들의 분류 방법이 더 우수하며 추적관찰 결과 만성 신부전의 예후 인자로써 유용하다고 발표하였다. IgA 신병증에서 임상 증세, 검사 소견, WHO 및 Yagame 등의 조직 병리학적 분류 등과 추적 관찰시 만성 신부전과의 상관 관계를 알아보고자 하였다. 방법 : 1984년 1월부터 1996년 2월까지 소아과에 입원하여 신생검상 메산지움에 IgA가 현저히 침착되어 있어 IgA 신병증으로 진단된 환아 79명을 대상으로 평균 27개월의 추적관찰시 신 기능이 정상인군(73례)과 만성 신부전으로 진행한 군(6례)을 서로 비교하여 IgA 신병증에서의 예후 예측 인자에 대하여 알아보고자 하였다. 결과 : 1) 성별, 나이, 증상기간 등은 양군간 차이가 없었으나 내원시 고혈압이 있을 경우 만성 신부전으로의 진행이 많았다. 2) 내원시에 여러 임상 검사중 심한 단백뇨가 만성 신부전으로의 진행이 많았다. 3) WHO 및 Yagame 등의 조직 병리학적 분류 모두 소아 환자에서는 예후와의 관련을 찾을 수 없었다. 결론 : 이상의 결과로 보아 IgA 신병증 환아에서 내원시에 심한 단백뇨, 고혈압이 있을 경우 추적 관찰 결과 예후가 좋지 않았다. 그러나 본 연구의 경우 치료에 대한 평가가 이루어지지 않았고 대상 환아가 적었기에 향후 이를 포함하는 광범위한 연구가 진행되어야 할 것으로 사료된다.

Objective : The restless legs syndrome (RLS) is a common disorder affecting up to 5% to 15% of the general population, in which the incidence increases with age, and includes paresthesia in the legs. The purpose of this study is to investigate the incidence of RLS in spine center and to review clinical manifestations of this syndrome and its current treatments. Methods : Over a period of a year, retrospective medical record review and lumbar magnetic resonance images were performed on 32 patients with RLS in spine clinic who were diagnosed by National Institutes of Health criteria. Affected limbs were classified as five. Two grading systems were used in the evaluation of neural compromises. Results : The incidence of RLS was 5.00% (32/639). There were 16 males (50%) and 16 females (50%). The median age at diagnosis was 55.4 years (range, 25-93 years). There are no correlation between the affected limbs of RLS and neural compromises on the lumbar spine. Conclusion : The RLS is a clearly common neurologic disorder of the limbs, usually the legs. The awareness of this syndrome can help reduce diagnostic error; thereby, avoiding the morbidity and expense associated with unnecessary studies or inappropriate treatments in RLS patients.

$^{67}Ga$ scintigraphy has been used in the evaluation of sarcoidosis, particularly for delineating sites of involvement and grading activity. Three patients admitted in SNUH between Jan. 1986 and Jun. 1987 were diagnosed as sarcoidosis after clinical examination and $^{67}Ga$ scintigraphy. $^{67}Ga$ scintigraphy disclosed increased uptake of radioactivity in both hilar region, mediastinum, both lacrimal glands and parotid glands prior to treatment. In one case after prednisolon therapy, there was definit improvement of clinical findings and $^{67}Ga$ scintigraphy was normalized.
