Purpose: Frey's syndrome is a common complication after parotid surgery and characterized by gustatory sweating and flushing in the periauricular area during meals. Although a variety of methods have been proposed to prevent this postoperative problem but they have been unsatisfactory. In this article, therefore, botulinum toxin A was used to treat nine patients with Frey's syndrome and its duration effect after injection was investigated. Methods: Nine patients became the object of study about the effect of botulinum toxins as treatment of Frey's syndrome. Age of patients ranged from 25 to 78 years (mean, 43.7 years). Six of nine patients had both symptoms of gustatory sweating and flushing. And the others had only gustatory sweating symptom. Using Minor starch iodine test, the affected skin area was detected, and it was marked by $1cm^2$ sized grid appearance. After application of EMLA cream on the gustatory sweating area, botulinum toxin A was injected intracutaneously into the affected skin area ($2.5U/cm^2$). Patients were followed up from six to fifteen months (mean, about 12 months) and asked about improvement of their symptoms. Results: The treatement with botulinum toxin A took effective within two days after injection. Six months after injection, gustatory sweating disappeared completely in all patients, and five of six patients who had gustatory flushing improved in their symptom. Last follow-up, no patients complained of recurrent gustatory sweating and flushing except one. One patient, seven months after initial injection, was retreated with botulinum toxin A because of recurrence, and the result was successful. The duration of the effect after botulinum toxin A treatment was ranged from seven to thirteen months. One patient in our series experienced the upper eyelid weakness as adverse effect, but it improved spontaneously. Conclusion: Local injection of botulinum toxin A is an effective, safe and long - lasting method for treatment of Frey's syndrome. Hereafter, however, additional study will be required to evaluate the duration effect of botulinum toxin A according to frequency in use and dosage.

최근 폐암의 발생빈도는 높아지고 있으나, 아직까지 만족할 만한 치료 성적은 제시되시 많고 있으며, 현재로서는 가능한 한 초기에 발견하여 수술을 시행후 국소재발 위험군의 경우 방사선 치료를 시행하는 것이 최선의 방법으로 알려져있다. 이에 저자들은 1979년 3월부터 1986년 2월까지 서울대학교 병원에서 비소세포성 폐암 진단하에 근치적 절제수술 시행후 방사선 치료를 받은 60명의 환자를 대상으로 수술후 방사선 치료의 효과 및 예후인자에 대한 분석을 시행하여 다음과 같은 결과를 얻었다. 전체 환자 60명중 방사선 치료를 불완전하게 시행한 5명을 제외한 55명을 분석한 결과 전체 환자의 5년 생존율은 $39\%$였으며 무병생존율은 $29\%$였다. 환자의 예후를 결정하는 주요인자로서는 병기 및 국소 임파절 전이 여부였고, 1병기와 병리조직학적 분류 및 나이, 성별, 방사선 조사선량과 수술시 절제면의 종양 침범 여부는 예후에 큰 영향을 미치지 못하였다. 수술 시행후 방사선 치료를 받은 환자 군의 생존율은, 문헌상에 나타난 수술 단독 시행 환자군의 생존율과 비교해 볼 때 국소 임파절 전이가 있는 환자군에서 더 높은 결과를 보였으며, 임파절 전이가 없는 환자군에서는 큰 차이를 발견할 수 없었다. 국소 재발율도 임파절 전이가 있는 환자군에서는 수술 단독 시행 환자군보다 현저히 낮은 결과를 보여 수술후 방사선 치료가 임파절 전이가 있는 환자에게는 생존율의 증가 및 국소재발 억제의 효과를 나타냄을 관찰할 수 있었다.

1979년부터 1985년까지 서울대학교병원 치료방사선과에서 외부 방사선조사를 시행한 15명의 뇌하수체상부 배아세포종(전이송과선종) 환자에 대한 후향적 분석을 시행하였다. 생존자의 추적기간은 $30\~91$개월이었다. 10명의 환자는 방사선치료 전 조직학적으로 진단되었으며 나머지 5명은 조직학적 진단이 없이 방사선치료를 시행하였단 조직학적으로 진단된 9명중 배아세포종 환자 6명은 전뇌와 척추에 3명은 전뇌 조사를 시행하였다. 혼합 배아세포종 및 종양 marker양성인 5명의 환자 중 2명은 전뇌, 그리고 1명은 원발병소 부위에만 방사선치료를 시행하였다. 총 방사선량은 원발병소에 $5,000\~5,500 cGy$, 전뇌에 $3,000\~4,400 cGy$ 그리고 척추에 >$1,300\~3,000 cGy$였다. 상기 그룹 14명의 환자에서 원발병소는 완전 관해 되었으며 척추실패는 관찰되지 많았다. 조직학적 진만이 없고 marker의 상승이 없었던 한 환자에서 전뇌 방사선조사를 시행하였으나 원발병소의 완전관해 없이 척추 재발이 발생하였다. 방사선치료는 뇌하수체상부 배아세포종에 유효한 치료방법이며 신경 내분비학적 양상과 함께 조직학적 진단이 불가능한 경우에 있어서 소량의 방사선치료 후 관해정도 관찰은 이후의 치료방향설정에 유용한 수단으로 이용될 수 있다.

Purpose: Congenital insensitivity to pain with anhidrosis(CIPA) is a rare form of autosomal recessive peripheral sensory neuropathy. Patients with CIPA show loss of pain sensation, which leads to corneal ulcers and opacities, self-mutilation of the tongue and fingertips, as well as fractures with subsequent joint deformities and chronic osteomyelitis. The purpose of this report is to highlight the fact that pressure sores also are a potential complication of CIPA. Methods: This case report describes a patient presenting with pressure sores resulting from CIPA. A 5-year-old boy was referred to our department for the treatment of a $5{\times}5cm$ sacral pressure sore as a result of a hip spica cast applied for the treatment of a left hip joint dislocation. He had a history suggesting CIPA such as multiple bony fractures, mental retardation, recurrent hyperpyrexia, anhidrosis, and clubbing fingers due to oral mutilation. A microscopic examination of the sural nerve showed mainly large myelinated fibers, a few small myelinated fibers and an almost complete loss of unmyelinated fibers. After wound preparation for two weeks, the exposed bone was covered with two local advancement flaps. Results: Two weeks later, complete wound healing was achieved. A 16-month follow-up showed no recurrence. However, the patient presented with a new pressure sore on the left knee due to orthosis for the treatment of the left hip joint dislocation. Conclusion: The early diagnosis of CIPA and special care of pressure sores are important for preventing and treating pressure sores resulting from CIPA.

Objective : Meralgia paresthetica (MP) is a syndrome of pain and/or dysesthesia in the anterolateral thigh that is caused by an entrapment of the lateral femoral cutaneous nerve (LFCN) at its pelvic exit. Despite early accounts of MP, there is still no consensus concerning the effectiveness of neurolysis or transaction treatments in the long-term relief for medically refractory patients with MP. We retrospectively analyzed available long-term results of LFCN neurolysis for medically refractory MP in an effort to clarify this issue. Methods : During the last 7 years, 11 patients who had neurolysis for MP were enrolled in this study. Nerve entrapment was confirmed preoperatively by electrophysiological studies or a positive response to local anesthetic injection. Decompression of the LFCN was performed at the level of the iliac fascia, inguinal ligament, and fascia of the thigh distally. The outcome of surgery was assessed 8 weeks after the procedure followed at regular intervals if symptoms persisted. Results : Twelve decompression procedures were performed in 11 patients over a 7-year period. The average duration of symptoms was 8.5 months (range, 4-15 months). The average follow-up period was 33 months (range, 12-60 months). Complete and partial symptom improvement were noted in nine (81.8%) and two (18.2%) cases, respectively. No recurrence was reported. Conclusion : Neurolysis of the LFCN can provide adequate pain relief with minimal complications for medically refractory MP. To achieve a good outcome in neurolysis for MP, an accurate diagnosis with careful examination and repeated blocks of the LFCN, along with electrodiagnosis seems to be essential. Possible variation in the course of the LFCN and thorough decompression along the course of the LFCN should be kept in mind in planning decompression surgery for MP.

Background: Postoperative adjuvant radiotherapy (RT) in the management of early stage endometrial cancer (EC) is still controversial. Here we report our institutional experience with patients who received postoperative RT for stage I-II EC over a period of 35 years and assess potential predictors of local recurrence (LR), distant metastasis (DM), and overall survival (OS). Materials and Methods: A total of 188 patients undergoing postoperative RT for stage IA-II EC between 1977 and 2012 were evaluated. Some 96 received median 46 Gy whole pelvic radiotherapy (WPRT) (range: 40-60 Gy), 37 were given WPRT with vaginal cuff therapy (VCT), and 55 received only VCT either with brachytherapy (BT) or stereotactic body radiotherapy (SBRT). Chemotherapy was given to 5 patients with uterine papillary serous carcinoma (UPSC). Logistic regression analysis was used to assess the effect of clinicopathological factors on LR, DM, and OS. Results: Median follow-up time was 11 years (range: 1-35 years). At the time of analysis, 34 patients were not alive. Of the 15 patients with LR, 7 (46.7%) recurred in the vaginal stump, 5 (33.3%) in the pelvic region, and 3 (20%) in the paraaortic nodal region, while 12 had distant metastasis. UPSC histology (p=0.027), sole VCT (p=0.041), high histologic grade (p=0.034), and age ${\geq}71$ (p=0.04) were poor prognostic factors on univariate analysis. Conclusions: In our patients receiving radiotherapy for early-stage EC, grade III disease and age ${\geq}71$ were associated with shorter OS whereas UPSC histology was an independent predictor for both LR and DM.

Purpose: The purpose of this study is to evaluate the safety and efficacy of the multimodality treatment with neoadjuvant intensity-modulated radiotherapy (IMRT) for resectable clinical T1-3N0-1M0 malignant pleural mesothelioma (MPM). Materials and Methods: A total of eleven patients who received neoadjuvant chemotherapy and radiotherapy between March 2016 and June 2018 were reviewed. Patients received 25 Gy in 5 fractions to entire ipsilateral hemithorax with helical tomotherapy. Results: All of patients were men with a median age of 56 years. Epithelioid subtype was found in 10 patients. All patients received neoadjuvant chemotherapy with pemetrexed-cisplatin regimen. Ten patients (90.9%) completed 25 Gy/5 fractions and one (9.0%) completed 20 Gy/4 fractions of radiotherapy. IMRT was well tolerated with only one acute grade 3 radiation pneumonitis. Surgery was performed 1 week (median, 8 days; range, 1 to 15 days) after completing IMRT. Extrapleural pneumonectomy was performed in 4 patients (36.3%), extended pleurectomy/decortication in 2 (18.2%) and pleurectomy/decortications in 5 (63.6%). There was no grade 3+ surgical complication except two deaths after EPP in 1 month. Based on operative findings and pathologic staging, adjuvant chemotherapy was delivered in 7 patients (63.6%), and 2 (18.2%) were decided to add adjuvant radiotherapy. After a median follow-up of 14.6 months (range, 2.8 to 30 months), there were 3 local recurrence (33.3%) and 1 distant metastasis (11.1%). Conclusion: Neoadjuvant entire pleural IMRT can be delivered with a favorable radiation complication. An optimal strategy has to be made in resectable MPM patients who would benefit from neoadjuvant radiation and surgery. Further studies are needed to look at long-term outcomes.

Triple negative breast cancer (TNBC) is an aggressive subtype of breast cancer (BC) with higher metastatic rate and both local and systemic recurrence compared to non-TNBC. The generation of reactive oxygen species (ROS) secondary to oxidative stress is associated with DNA damage, chromosomal degradation and alterations of both hypermethylation and hypomethylation of DNA. This study concerns differential methylation of promoter regions in specific groups of genes in TNBC and non-TNBC Saudi females in an effort to understand whether epigenetic events might be involved in breast carcinogenesis, and whether they might be used as markers for Saudi BCs. Methylation of glutathione S-transferase P1 (GSTP1), T-cadherin (CDH13), Paired box protein 5 (PAX5), death associated protein kinase (DAPK), twist-related protein (TWIST), DNA-binding protein inhibitor (ID4), High In Normal-1 (HIN-1), cyclin-dependent kinase inhibitor 2A (p16), cyclin D2 and retinoic acid receptor-${\beta}$ ($RAR{\beta}1$) genes was analyzed by methylation specific polymerase chain reaction (MSP) in 200 archival formalin-fixed paraffin embedded BC tissues divided into 3 groups; benign breast tissues (20), TNBC (80) and non-TNBC (100). The relationships between methylation status, and clinical and pathological characteristics of patients and tumors were assessed. Higher frequencies of GSTP1, ID4, TWIST, DAPK, PAX5 and HIN-1 hypermethylation were found in TNBC than in non-TNBC. Hypermethylation of GSTP1, CDH13, ID4, DAPK, HIN-1 and PAX5 increased with tumor grade increasing. Other statistically significant correlations were identified with studied genes. Data from this study suggest that increased hypermethylation of GSTP1, ID4, TWIST, DAPK, PAX5 and HIN-1 genes in TNBC than in non-TNBC can act as useful biomarker for BCs in the Saudi population. The higher frequency of specific hypermethylated genes paralleling tumor grade, size and lymph node involvement suggests contributions to breast cancer initiation and progression.
