Brachyonychia is the condition when the width of the nail plate and nail bed is greater than their length. We describe a 21-year-old man who presented with brachyonychia and a 4th middle phalangeal defect on the left foot. Both the 4th metatarsal bones are shorter than the 5th ones on X-ray examination. He had no family history and other anomalies such as facial abnormalities and mental retardation.

PURPOSE: To evaluate the effect of repeated debulking surgery for high-grade pseudomyxoma peritonei (PMP) originating from the appendix.METHODS: Between January 1998 and December 2014, fifty patients, who underwent debulking surgery for high-grade PMP originating from the appendix, were obtained from a prospectively collected database and retrospectively analyzed. Two groups according to the number of operations were divided and analyzed.RESULTS: A total of 118 operations were performed. Thirty-one patients received more than two operations. The median interval between operations was 18.2 months (range, 2–170 months). Complications developed after 26 operations (22.0%), including ileus (n=10), intra-abdominal fluid collection (n=7), surgical site infection (n=5), and others. There were two mortalities within 30 days after operation. Between two groups of patients who received one operation only and patients who received more than two operations, transfusion, diversion operation, and postoperative complication rate showed statistically significant differences. Two groups of patients had no differences in overall survival rates.CONCLUSION: Our results indicate that the number of operations does not affect the survival rate of high-grade appendiceal PMP, in which repeated debulking surgery is vital to relieve symptoms of the tumor burden.

PURPOSE: To evaluate the efficacy of the in situ late osteosynthesis for slightly displaced fractures of the lateral humeral condyle. MATERIALS AND METHODS: From 2000 to 2004, 12 patients (8 boys and 4 girls) were managed with in situ late osteosynthesis for fractures of the lateral humeral condyle. The average age at the time of operation was 6 years 1 month (1 year 7 months~9 years 1 month), and the mean amount of fragment displacement was 3.3 mm (2.0~4.5 mm). The operative procedure included curettage and in situ fixation of the fragment RESULTS: Bony union was achieved in all cases after avg. 48 months (33~73 months) follow-up assessment. According to the score system of Dhillon et al, 7 patients had excellent, 3 had good, 2 had fair results. None of the patients developed avascular necrosis or premature closure of the epiphysis. CONCLUSION: We suggest that in situ fixation is an effective method for the late treatment of slightly displaced fracture of the lateral humeral condyle.

OBJECTIVE: This study was conducted to elucidate neuroprotective effect of carnosine in early stage of stroke. METHODS: Early stage of rodent stroke model and neuroblastoma chemical hypoxia model was established by middle cerebral artery occlusion and antimycin A. Neuroprotective effect of carnosine was investigated with 100, 250, and 500 mg of carnosine treatment. And antioxidant expression was analyzed by enzyme linked immunosorbent assay (ELISA) and western blot in brain and blood. RESULTS: Intraperitoneal injection of 500 mg carnosine induced significant decrease of infarct volume and expansion of penumbra (p<0.05). The expression of superoxide dismutase (SOD) showed significant increase than in saline group in blood and brain (p<0.05). In the analysis of chemical hypoxia, carnosine induced increase of neuronal cell viability and decrease of reactive oxygen species (ROS) production. CONCLUSION: Carnosine has neuroprotective property which was related to antioxidant capacity in early stage of stroke. And, the oxidative stress should be considered one of major factor in early ischemic stroke.

PURPOSE: Neuroendocrine tumor is a rare tumor in the rectum, but incidence has been increasing. Local excision is an option for treatment of small tumors, and transanal excision or endoscopic resection can be undergone. But indications for local excision have not been established yet. This study was to compare the long-term oncologic outcomes between transanal excision and endoscopic resection for rectal neuroendocrine tumor.METHODS: Patients diagnosed and treated with rectal neuroendocrine tumor from 2000 to 2015 were collected prospectively, and medical records were analyzed retrospectively.RESULTS: Forty patients were included, mean age was 50.20±13.35 years (male:female=23:17). Transanal excision and endoscopic resection were performed in 28 (70%) and 12 (30%) patients, respectively. Mean tumor size was 0.63±0.37 cm, and tumor location was 5.45±1.89 cm from anal verge. Tumor location was more distal rectum in transanal excision (5.04±1.73 cm vs. 6.42±1.98 cm, P=0.049). Pathologic T stage was T1 in all patients. Most of the patients (90%) showed tumor grade 1. After median 24 months (range, 0–86 months) follow-up, one patient (2.5%) experienced local recurrence. The patient underwent further transanal excision. There was no mortality after local excision.CONCLUSION: Local excision is a safe and effective treatment for small-sized neuroendocrine tumors in rectum.

Purpose: Endoscopic tattooing is used to mark colorectal lesions for subsequent surgery. As a tattooing agent, India ink has been widely used but is not currently available in Korea. Indocyanine green (ICG) can be applied as an alternative agent. However, studies on colonoscopic tattooing by the direct injection of indocyanine green are lacking. This study aimed to compare the efficacy and safety between an ICG direct injection method and an India ink saline test injection method. Methods: A total of 227 patients who underwent preoperative endoscopic tattooing for colorectal neoplasm (149 patients in the ICG direct injection group and 78 patients in the India ink saline test injection group) were included in the study. The efficacy of the two methods was compared by visualization and safety was compared by evaluating the perioperative tattooing complications. Results: The visualization of lesions in the ICG group was not different from that of the India ink group (p=0.42, 96.0% vs 98.7%, respectively). Only one patient in the ICG group had abdominal pain related to tattooing, but no complications developed in the India ink group. Conclusion Considering the good visualization and low complication rate, the direct injection of ICG can be used as an alternative tattooing method.

PURPOSE: This study investigated the effects of multiple drilling on the immature capital femoral epiphysis following ischemic injury in a piglet model. MATERIALS AND METHODS: Ischemic necrosis of capital femoral epiphysis was induced bilaterally in 12 piglets using a cervical ligation method. Three weeks later, medial, central, and lateral 3 drill holes were made on the left femoral head using 0.062" K-wire. At 3, 6, 9, and 12 weeks following the multiple drilling, femoral heads were harvested from each three piglets. On histologic examination, percent of revascularization, percent of osteoblast surface, capital femoral epiphyseal quotient and proximal femoral growth plate height were evaluated. Untreated right femoral heads served as control. RESULTS: While percent of revascularization of left capital femoral epiphysis with multiple drilling was significantly higher than untreated control side (p<0.001), percent of osteoblast surface, capital femoral epiphyseal quotient and proximal femoral growth plate height showed no significant difference. CONCLUSION: This study indicates that multiple drilling could promote revascularization of ischemic capital femoral epiphysis, and multiple drilling does not appear to produce bony physeal bars at short-term, if using small diameter drill. However, multiple drilling alone does not seem to prevent femoral head deformity or to promote new bone formation.

With the increased use of implantable cardiac devices, the incidence of hardware problems has also increased. Some of the hardware problems might be induced by patient factors. We experienced recurrent pacemaker lead fracture and dislocation after permanent pacemaker implantation. The patient was a bus driver who used his left arm vigorously when he turned the steering wheel. After a new lead was inserted via an axillary vein approach and the patient changed his occupation, no more lead problems have occurred. When a recurrent hardware problem with an implantable pacemaker or defibrillator occurs, patient factors related to anatomy or behavior must be considered.

PURPOSE: Interstitial cells of Cajal (ICC) play a core function in colonic motility as a pacemaker by regulating the slow wave. We intended to investigate the electrophysiological characteristics of the circular smooth muscle in the human colon, especially in Koreans. METHODS: Colon tissues were obtained from patients undergoing an elective colectomy for non-obstructive lesions. Tissues were immediately stored in oxygenated Krebs-Ringer's bicarbonate solution, and conventional microelectrode recordings of the colonic circular muscle were done from muscle cells. RESULTS: The trans-membrane potentials from 100 tissues were recorded. Regular slow-wave patterns were observed in 36 patients, and 64 patients showed irregular wave patterns. In the tissues exhibiting regular slow-wave patterns, 20 tissues were recorded from the proximal colon and 16 from the distal colon. The frequency of the slow wave from the proximal part was significantly higher than that from the distal part. The resting membrane potential, the upstroke amplitude, the spike amplitude, and the maximal rate of rise showed no significant difference between the two parts, but the time to reach half amplitude did show a significant difference between the two parts. No significant differences in parameters were observed based on the patients' demographics such as sex and age (younger or older than 60). We were able to divide the irregular waves into 3 groups. Irregular slow waves were observed in 35 tissues, irregular slow waves mixed with spike waves were observed in 26 tissues, and spike waves alone were observed in 3 tissues. CONCLUSION: We analyzed the electrophysiological characteristics of the human colonic circular smooth muscle, especially those of the slow wave originating from ICC of patients who had not been pretreated with drugs.
