A 60-year-old man presented with a 3-week history of pruritic bullae and erosions located within an acupuncture site on the right lower leg. Ten days prior to the development of these bullae, he had been treated with acupuncture to the right calf due to Achilles tendonitis which had developed 1 year earlier. The diagnosis of bullous pemphigoid was confirmed by histologic findings and salt-split direct immunofluorescence study performed on the perilesional skin. To our knowledge, this is the first case of localized bullous pemphigoid following acupuncture.

Purpose: The aim of this study was to review our experience with laparoscopic-assisted colectomy (LACs), and to evaluate its feasibility and safety for surgical treatment of colorectal diseases, including cancer. Methods: Between September 2002 and September 2005, a LAC was performed in 58 patients. Of these, 6 cases of conversion to open colectomy were excluded from the analysis. Fifty conventional open colectomy (OCs) with clinicopathologic characteristics comparable to those of the LACs were selected and matched as a control group for comparative analysis regarding short-term oncologic and perioperative outcomes. The mean follow-up period was 13.8 (2~37) months. Results: Thirteen complications, involving 11 patients, occurred. The mean operative time of the LAC was longer than that of the OC (215 min vs. 179 min; P<0.0001). However, earlier restoration of bowel function was achieved in the LAC as measured by postoperative first flatus (2.8 days vs. 3.8 days) and intake of a clear liquid diet (4.7 days vs. 5.8 days). There was no significant difference in hospital stay (LAC vs. OC, 10.2 days vs. 11.8 days). In patients with malignancy, the proximal resection margin in the LAC was significantly shorter than that in the OC (9.2 cm vs. 13.3 cm; P<0.0001). However, there were no significant differences in the mean numbers of harvested lymph nodes (LAC vs. OC, 16.6 vs. 19.3; P=0.4330) and the mean distal resection margins (LAC vs. OC, 6.9 cm vs. 6.0 cm; P=0.1359). There were 3 distant metastases and one local recurrence during follow-up in the LAC group, but no port-site recurrence. Conclusions: In this study, we could not receive an advantage of shorter hospital stay due to the relatively high complication rate for a LAC, which may reflect a learning curve. Earlier postoperative recovery of bowel function and equal pathologic extent of resection in the LAC suggest that the LAC is an acceptable alternative procedure in the treatment of colorectal diseases, including malignancy. More experience with the LAC is necessary to overcome the learning curve. Affirmative long-term oncologic outcomes of are expected for the LAC.

BACKGROUND: To investigate the sleep disorders related to chronic insomnia and compare the characteristics of each group. METHODS: We registered 191 patients (female 56.0%, age 61.7 years) who have complained about symptoms of insomnia for more than three months and assessed sleep disorders related chronic insomnia by analyzing their polysomnography (PSG) parameters, demographics, and questionnaires (Insomnia Severity Index, Beck Depression Inventory, Pittsburg Sleep Quality Index, and Epworth Sleepiness Scale, and World Health Organization Quality of Life Assessment Instrument abbreviated version). RESULTS: Patients were categorized into groups of primary insomnia (PI, 51.8%, n=99), comorbid insomnia with obstructive sleep apnea (CIO, 38.7%, n=74), and comorbid insomnia with periodic limb movement disorder (CIP, 9.4%, n=18). CIO was older and more obese than PI and CIP. The proportion of males was the highest in CIO. Arousal index of PSG was higher in CIO and CIP than in PI. Other parameters and the results of questionnaires were not different among groups. CONCLUSIONS: About a half of patients with chronic insomnia symptoms (48.2%) had considerable sleep disorders associated with insomnia. Our study suggests that the PSG as well as history taking and demographics are necessary to clarify the relevant conditions of chronic insomnia disorder for appropriate treatment.

PURPOSE: To assess the clinical features and outcomes of patients referred for management of dropped lens fragments during cataract surgery. METHODS: The medical records of 22 eyes from 22 patients who were referred to our hospital to undergo pars plana vitrectomy (PPV) for management of dropped lens fragments after phacoemulsification surgery at private clinics were reviewed. Data including patient demographics, preoperative and postoperative visual acuity, factors associated with dropped lens fragment, and postoperative complications were recorded. The factors were compared between 2 patient groups: postoperative Snellen acuity of 0.5 or better and acuity less than 0.5. The statistical significances of differences in factors between the 2 groups were calculated. RESULTS: The mean interval between cataract surgery and PPV was 2.6 +/- 3.7 days. At the final examination, the mean postoperative acuity was 0.57 +/- 0.20, and 16 eyes (72.7%) had a visual outcome of 0.5 or better. After excluding 7 eyes with other pre-existing ocular co-morbidities, 14 eyes (93.0%) achieved a final visual acuity of 0.5 or better. Multivariate analysis showed that the predictor for visual outcomes of 0.5 or better was absence of preoperative eye disease (p = 0.007). Complications after PPV included 2 (9.0%) cases of cystoid macular edema and 1 (4.5%) case of retinal detachment. CONCLUSIONS: Prompt referral and surgical management within 1 week for dropped lens fragments during cataract surgery may achieve a better visual outcome in cases with no pre-existing eye disease.

BACKGROUND: Liver transplantation (LT) is a complicated procedure with a high incidence of postoperative acute kidney injury (AKI). Previous studies indicate that even transient or mild post-LT AKI can result in critical conditions, including prolonged stays in hospitals and intensive care units and increased morbidity and mortality. The aim of this study was to investigate the association between body mass index (BMI) and occurrence of AKI in LT recipients. METHODS: Medical data from 203 patients who received LT surgery from January 2010 to August 2016 in a single university hospital setting were retrospectively collected and analyzed. Patients were classified as either underweight (BMI <20 kg/m²) or normal weight (20 ≤ BMI < 30 kg/m²). Demographic data, anesthetic methods, complications, and perioperative laboratory test values of each patient were assessed. Propensity analyses and logistic regression were performed to evaluate the association between BMI and post-LT AKI. RESULTS: There was no significant difference in occurrence of post-LT AKI between underweight and normal weight patients. The underweight patient group had significantly longer hospital stay compared with the normal weight patient group (P = 0.023). CONCLUSIONS: BMI classification was neither a positive nor negative predictor of postoperative AKI occurrence. However, patients with lower BMI had significantly longer hospital stay compared with their counterparts. Although our study was limited by its retrospective design, our observations suggest that lower BMI might play a role in post-LT AKI.

OBJECTIVE: To report the latest long-term outcome of amyotrophic lateral sclerosis (ALS) and to analyze the predictors of prognosis. METHODS: Subjects who were diagnosed with ALS between January 2005 and December 2009 at a single institute were followed up until death or up to December 2014. Data regarding age, sex, date of onset, date of diagnosis, presence of bulbar symptoms on onset, date of initiation of non-invasive ventilation (NIV), and the date of tracheostomy were collected. Survival was assessed using Kaplan-Meier curves and multivariate analyses of the risk of death were performed using the Cox proportional hazards model. RESULTS: Among 212 suspicious subjects, definite ALS was diagnosed in 182 subjects. The survival rate at 3 and 5 years from onset was 61.5% and 40.1%, respectively, and the survival rate at 3 and 5 years post-diagnosis was 49.5% and 24.2%, respectively. Further, 134 patients (134/182, 73.6%) were initiated on NIV, and among them, 90 patients (90/182, 49.5%) underwent tracheostomy. Male gender and onset age of ≥65 years were independent predictors of adverse survival. CONCLUSION: The analysis of long term survival in ALS showed excellent outcomes considering the overall poor prognosis of this disease.

The purpose of this study was to assess dental hygienists' awareness of medical technician jurisprudence. The study was conducted over a 2-month period from March 1 to May 1, 2016. A self-reported questionnaire was completed by 201 dental hygienists in Seoul, Gyeonggi, and Incheon province. The questionnaire consisted of items on the awareness of the jurisprudence pertaining to medical technician jurisprudence. Data were analyzed using the IBM SPSS Statistics ver. 19.0 program. We found that 32.8% of the respondents were aware of medical technician jurisprudence. Low awareness that result was due to “insufficient public relations efforts.” The respondents thought that medical technician jurisprudence are inefficient in clinical settings. Of the dental hygienists, 75.9% replied that task distribution was unclear and 40.0% lacked awareness of the distribution of dentists' duties (40.0%). A total of 59.8% of respondents showed intention to participate in medical jurisprudence seminars. Of the dental hygienists, 77.0% agreed with the insert dental hygienists under medical jurisprudence category. In conclusion, dental hygienists' awareness of medical technician jurisprudence should be improved. In addition, the dental hygienist jurisprudence need to be revised regarding job status.

Soft tissue myoepithelioma is a rare neoplasm composed of myoepithelial cells. Here, we describe the cytologic features of soft tissue myoepithelioma arising on the right forearm in an 18-year-old man. The excised tumor (3.0x1.8x1.5 cm) was well-demarcated, yellow-gray, soft, and myxoid. The cytologic smears showed round to spindle, epithelioid, and plasmacytoid cells in the myxoid background. The nuclei were uniform, round to ovoid, with finely distributed chromatin and eosinophilic or pale cytoplasm. The tumor cells demonstrated immunoreactivity for cytokeratin (AE1/AE3), epithelial membrane antigen, S100 protein, and glial fibrillary acidic protein. Electron microscopy showed intermediate filaments, desmosomes, and basal lamina.

The proteasome inhibitor, bortezomib, is ineffective against many solid tumors. Nutlin-3 is a potent antagonist of human homolog of murine double minute 2/p53 interaction exhibiting promising therapeutic anti-cancer activity. In this study, we show that treatment of various p53-defective bortezomib-resistant solid tumor cells with bortezomib plus nutlin-3 induces paraptosis, which is a cell death mode accompanied by dilation of the endoplasmic reticulum (ER) and mitochondria. Bortezomib alone did not markedly alter cellular morphology, and nutlin-3 alone induced only a transient mitochondrial dilation. However, bortezomib/nutlin-3 co-treatment triggered the progressive fusion of swollen ER and the formation of megamitochondria, leading to cell death. Mechanistically, proteasomal-impairment-induced ER stress, CHOP upregulation and disruption of Ca²⁺ homeostasis were found to be critically involved in the bortezomib/nutlin-3-induced dilation of the ER. Our results further suggest that mitochondrial unfolded protein stress may play an important role in the mitochondrial dilation observed during bortezomib/nutlin-3-induced cell death. Collectively, these findings suggest that bortezomib/nutlin-3 perturbs proteostasis, triggering ER/mitochondria stress and irrecoverable impairments in their structure and function, ultimately leading to paraptotic cell death.

PURPOSE: To assess the influence of body position on intraocular pressure (IOP) in patients who underwent vitrectomy and intraocular gas tamponade. METHODS: Patients who did not undergo any surgery were defined as Group 1. The remaining patients were divided into 3 groups according to the surgery performed (Group 2; cataract surgery, Group 3; vitrectomy and cataract surgery, Group 4; vitrectomy with intraocular gas tamponade and cataract surgery). IOP was measured by a non-contact tonometer, Goldmann applanation tonometer, and Tono-Pen in the sitting, supine, and prone positions. RESULTS: The difference of IOP measured in the sitting position among the 4 groups was not significant. IOP was significantly elevated by 2.04 mm Hg on average when the posture was changed from sitting to supine or prone in all 4 groups. The IOP discrepancy between supine and sitting positions was significantly greater in group 4 by 3.61 mm Hg than the other groups (p = 0.003, ANOVA test). The IOP difference between the prone and sitting position was also significantly higher in group 4 by 3.82 mm Hg than the other groups (p = 0.001, ANOVA test). CONCLUSIONS: The patients with vitrectomized gas tamponade eyes had a mean IOP increase of 3.82 mm Hg when the position was changed from sitting to prone. When performing vitrectomy and intraocular gas tamponade on patients in the prone position, an IOP elevation should be monitored thoroughly.
