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.

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: 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.

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.

BACKGROUND: Increasing evidence supports an association between age-related loss of muscle mass and insulin resistance. However, the association has not been fully investigated in the general population. Thus, we investigated the association between appendicular skeletal muscle mass (ASM) and insulin resistance in an elderly Korean population. METHODS: This cross-sectional study included 158 men (mean age, 71.8) and 241 women (mean age, 70.6) from the Korean Social Life, Health and Aging Project, which started in 2011. In this study, ASM was measured by bioelectrical impedance analysis and was analyzed in three forms: ASM (kg), ASM/height2 (kg/m2), and ASM/weight (%). The homeostasis model assessment of insulin resistance (HOMA-IR) was used as a measure of insulin resistance. The relationships between the ASM values and the HOMA-IR were investigated by multiple linear regression models. RESULTS: The HOMA-IR was positively associated with ASM (beta=0.43, P<0.0001) and ASM/height2 (beta=0.36, P<0.0001) when adjusted for sex and age. However, after additional adjustment for body weight, HOMA-IR was inversely associated with ASM (beta=-0.43, P<0.001) and ASM/height2 (beta=-0.30, P=0.001). Adjustment for other potential confounders did not change these associations. Conversely, HOMA-IR was consistently and inversely associated with ASM/weight before and after adjustment for other potential confounders. CONCLUSION: Our results support the idea that lower skeletal muscle mass is independently associated with insulin resistance in older adults. When evaluating sarcopenia or muscle-related conditions in older adults, their whole body sizes also need to be considered.

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.

BACKGROUND: It is known that there is a pronounced circardian periodicity for the time of onset of acute myocardial infarction(AMI), with prominent increase in incidence of onset in the morning hours. However, the characteristic circardian variability in AMI is blunted in patients receiving beta-blockers or aspirin therapy before their presentation with AMI. These findings are attributed to the increase in platelet aggregability, blood coagulability, and plasma catecholamine that change coronary tone and myocardial oxygen demand. We hypothesize that, in addition to above physiologic and biochemical parameters, morphologic patterns of the coronary artery lesions are related to the development of circardian variation in AMI. METHOD: Subjects were 160 patients with AMI(male 92, female 68, mean age 56.9 +/-10.5 years old). Patients were classified by the time of onset of typical chest pain(AMI) by 6-hour interval from mid-night. Circardian variability of onset of AMI was compared with clinical findings and coronary angiographic findings. RESULTS: Incidence of onset of AMI was most frequent in the morning hours(6AM-noon,42.5%). There was no difference in degree of stenosis, lesion length, incidence of intraluminal thrombus, among 3 subgroups of AMI according to time of attack. Morning hour group had more frequent ulceration of coronary lesion than that of other groups(22.4% vs. 5.4%, p<0.01), and less frequent calcified lesion than that of other groups(3.0% vs 5.4%, p<0.05). Normal or minimal coronary artery lesion, that is Iess than 25% stenosis, was more frequent in the morning hour group comparing to that of other groups(11.9% vs. 9.78%). Eccentric stenosis(15.7% vs, 11,1%) and diffuse irregular lesion(25.5% vs. 16.7%) tended to be more frequent in the morning hour group. There were no differences in sex, age, incidence of hypertension, cigarette smoking, diabetes, degree of alcohol ingestion, ejection fraction, maximal CK value, preinfarction angina duration, past history of MI, and in incidence of arrhythmia. CONCLUSIONS: There were more ulcerative coronary atherosclerotic lesions, but fewer calcified coronary lesions in the morning group than in afternoon and night group. These findings indicate that morphology of coronary artery lesions may play a role in causing circardian variation in AMI.
