Proliferating trichilemmal tumor is a rare benign tumor of skin appendage. It is usually solitary, more common in women after the fourth decade of life, and almost exclusively confined to the scalp and back of the neck. We report herein an unusual case of proliferating trchilemmal tumor which occurred on the knee.

Background: As the application of radiotherapy to brain metastasis (BM) increases, the incidence of radiation necrosis (RN) as a late toxicity of radiotherapy also increases. However, no specific treatment for RN is indicated except long-term steroids. Here, we summarize the clinical results of bevacizumab (BEV) for RN. Methods: Ten patients with RN who were treated with BEV monotherapy (7 mg/kg) were retrospectively reviewed. RN diagnosis was made using MRI with or without perfusion MRI. Radiological response was based on Response Assessment in Neuro-Oncology criteria for BM. The initial response was observed after 2 cycles every 2 weeks, and maintenance observed after 3 cycles every 3-6 weeks of increasing length intervals. Results: The initial response of gadolinium (Gd) enhancement diameter maintained stable disease (SD) in 9 patients, and 1 patient showed partial response (PR). The initial fluid-attenuated inversion recovery (FLAIR) response showed PR in 4 patients and SD in 6 patients. The best radiological response was observed in 9 patients. Gd enhancement response was 6 PR and 3 SD between 15-43 weeks. Reduction of FLAIR showed PR in 5 patients and SD in 4 patients. Clinical improvement was observed in all but 1 patient. Five patients were maintained on protocol with durable response up to 23 cycles. However, 2 patients stopped treatment due to primary cancer progression, 1 patient received surgical removal from tumor recurrence, and 1 patient changed to systemic chemotherapy for new BM. Grade 3 intractable hypertension occurred in 1 patient who had already received antihypertensive medication. Conclusion BEV treatment for RN from BM radiotherapy resulted in favorable radiological (60%) and clinical responses (90%). Side effects were expectable and controllable. We anticipate prospective clinical trials to verify the effect of BEV monotherapy for RN.

PURPOSE: The factors for predicting persistent urge symptom and urge incontinence following a tension-free vaginal tape (TVT) procedure were investigated in patients with mixed urinary incontinence. MATERIALS AND METHODS: Two hundred and seventy-four women, with a mean age of 55 years, ranging from 28 to 80, with female urinary incontinence (stress urinary incontinence; 201, mixed urinary incontinence; 73) were the subjects of this study. After a TVT procedure, the patients were followed up at 1, 6 and 12 months and every 1 year thereafter. Cure of incontinence after the procedure was defined as the absence of a subjective complaint of leakage and the absence of objective leakage on stress testing, with all other cases considered as failures. RESULTS: There was no significant difference in the cure rates for stress urinary incontinence in patients with stress and mixed urinary incontinence. However, of 73 patients with mixed urinary incontinence, 20 (27.4%) ans 12 (16.4%) had persistent urgency and continued urge incontinence, respectively. In a multivariate analysis, a low maximal urethral closure pressure (MUCP) was found to be associated with an increased likelihood of persistent urgency (odds ratio, 0.94; 95% confidence interval, 0.38-0.99; p=0.029) and the persistent urge incontinence (odds ratio, 0.94; 95% confidence interval, 0.88-0.99; p=0.030) after a TVT procedure in patients with mixed urinary incontinence. CONCLUSIONS: Our findings suggest that a low MUCP may be associated with the persistent urgency and urge incontinence after a TVT procedure in patients with mixed urinary incontinence.

Objective: We developed the Indoor Cognitive Training combined with Physical Activity (ICT-PA) program, incorporating memory registration, navigation, and image recall through wearable sensors and Bluetooth Low Energy tags, aimed at enhancing cognitive function and physical activity in elderly individuals with mild cognitive impairment (MCI). Methods: Thirty-six elderly individuals over 60 years diagnosed with MCI participated in a 6-week ICT-PA program. The primary outcome measure was the Consortium to Establish a Registry for Alzheimer’s Disease Neuropsychological Assessment Battery Total Score 1 (CERAD-TS1), and the secondary outcome measures were the Mini-Mental State Examination (MMSE), Subjective Memory Complaints Questionnaire (SMCQ), and Korean version of the Geriatric Depression Scale (GDS-KR). Changes in scores before and after the program were analyzed using paired t-tests. Program satisfaction was evaluated using a 5-point Likert scale. Results: CERAD-TS1 scores significantly improved after ICT-PA training (pre 57.3±11.3; post 60.3±13.1; p=0.006), while MMSE, SMCQ and GDS-KR scores remained unchanged. Subgroup analysis showed significant CERAD-TS improvements in the compliance group (>360 minutes of ICT-PA use) (pre 58.5±11.7; post 62.7±12.9; p=0.002). The average program satisfaction score was 7.7±1.6 out of 10. Data are presented as mean±standard deviation. Conclusion The ICT-PA program effectively improved cognitive functions in MCI patients, with high satisfaction rates.

PURPOSE: We have undertaken this study to evaluate the effects of induction chemotherapy involving BH-AC, idarubicin, and 6-thioguanine (6-TG). METHODS: BH-AC 300mg/m2/day was administered intravenously over three hours for seven consecutive days. Idarubicin 12mg/m2/day was administered intravenously for three days. 6-TG 100 mg/m2/day was administered orally for seven days. Intrathecal ara-C was administered on the first day of treatment. RESULTS: Complete remission (CR) was achieved in 18 cases (66.7%), partial remission (PR) was achieved in 2 cases (7.4%). In previously untreated patients, complete reimission rate was 92.9% (13/ 14), in relapsed patients, 40% (2/5) and in the refractory patients, 37.5% (3/8). The remission duration until December 1996 was 45 to 630 days (median 133). Duration of the neutropenia (ANC<500/microliter) was 0 to 38 days (median 24). Side effects were nausea, vomiting (7/27, 25.9%), liver dysfunction (1/27, 3.7%), skin eruption (1/27, 3.7%), and mucositis (1/27, 3.7%). In all cases, fever developed in the neutropenic state (culture proven sepsis in 5 cases). Death occurred in 5 cases who achieved CR due to sepsis after chemotherapy (4 cases), intracerebral hemorrhage after bone marrow relapse (1 case). CONCLUSION: BH-AC, idarubicin, and 6-TG induction chemotherapy could be a useful induction chemotherapy treatment that combines supportive care for infection and bleeding.

BACKGROUND: Video-assisted thoracoscopic surgery (VATS) pulmonary wedge resection has emerged as the standard treatment for primary spontaneous pneumothorax. Recently, single-port VATS has been introduced and is now widely performed. This study aimed to evaluate the outcomes of the Tower crane technique as novel technique using a 15-mm trocar and anchoring suture in primary spontaneous pneumothorax. METHODS: Patients who underwent single-port VATS wedge resection in Chungnam National University Hospital from April 2012 to March 2014 were enrolled. The medical records of the enrolled patients were reviewed retrospectively. RESULTS: A total of 1,251 patients were diagnosed with pneumothorax during this period, 270 of whom underwent VATS wedge resection. Fifty-two of those operations were single-port VATS wedge resections for primary spontaneous pneumothorax performed by a single surgeon. The median age of the patients was 19.3±11.5 years old, and 43 of the patients were male. The median duration of chest tube drainage following the operation was 2.3±1.3 days, and mean postoperative hospital stay was 3.2±1.3 days. Prolonged air leakage for more than three days following the operation was observed in one patient. The mean duration of follow-up was 18.7±6.1 months, with a recurrence rate of 3.8%. CONCLUSION: The tower crane technique with a 15-mm trocar may be a promising treatment modality for patients presenting with primary spontaneous pneumothorax.

Nephrogenic diabetes insipidus (DI) secondary to chronic urinary tract obstruction is a rare disease. The exact cause is unknown but it is likely that increased collecting duct pressures cause damage to the tubular epithelium, resulting in insensitivity to the action of arginine-vasopressin (AVP). A 77-year-old man complaining of polyuria and polydipsia was treated with alpha glucosidase inhibitor under the impression of polyuria due to diabetes mellitus. But his symptoms did not improve. Water deprivation and AVP administration study revealed that the patient had nephrogenic DI. Urinary tract obstruction due to an enlarged prostate was suggested as a principal cause of nephrogenic DI. The patient underwent transurethral resection of the prostate and bilateral subcapsular orchiectomy. After surgery, the urine osmolarity was normalized and the patient became symptom-free. We report a case of nephrogenic DI due to obstructive uropathy which was cured by surgery eliminating obstruction.

Stress-induced cardiomyopathy is caused by emotional or physical stressors and mimics acute myocardial infarction, though Stress-induced cardiomyopathy is characterized by reversible left ventricular (LV) apical ballooning in the absence of significant coronary artery disease. We describe a 51-year-old male who underwent left upper lobectomy for non-small cell lung cancer, and during which cardiogenic arrest occurred due to stress-induced cardiomyopathy, successfully managed by intra-aortic balloon pumping and extracorporeal membrane oxygenation.
