Purpose: Proper use of antibiotics during emergency abdominal surgery is essential in reducing the incidence of surgical site infection. However, no studies have investigated the type of antibiotics and duration of therapy in individuals with abdominal trauma in Korea. We aimed to investigate the status of initial antibiotic therapy in patients with solitary abdominal trauma. Methods: From January 2015 to December 2015, we retrospectively analyzed the medical records of patients with solitary abdominal trauma from 17 institutions including regional trauma centers in South Korea. Both blunt and penetrating abdominal injuries were included. Time from arrival to initial antibiotic therapy, rate of antibiotic use upon injury mechanism, injured organ, type, and duration of antibiotic use, and postoperative infection were investigated. Results: Data of the 311 patients were collected. The use of antibiotic was initiated in 96.4% of patients with penetrating injury and 79.7% with blunt injury. Initial antibiotics therapy was provided to 78.2% of patients with solid organ injury and 97.5% with hollow viscus injury. The mean day of using antibiotics was 6 days in solid organ injuries, 6.2 days in hollow viscus. Infection within 2 weeks of admission occurred in 36 cases. Infection was related to injury severity (Abbreviated Injury Scale of >3), hollow viscus injury, operation, open abdomen, colon perforation, and RBC transfusion. There was no infection in cases with laparoscopic operation. Duration of antibiotics did not affect the infection rate. Conclusion Antibiotics are used extensively (84.2%) and for long duration (6.2 days) in patients with abdominal injury in Korea.

Linear psoriasis is a rare form of psoriasis and is characterized by the linear distribution of the psoriatic lesions. It should be differentiated clinically and histopathologically from inflammatory linear verrucous epidermal nevus(ILVEN) or psoriasis occuring as part of the Koebner phenomenon. A 41-year-old female is described, who had developed linearly arranged psoriatic lesions in the right lower extremity over the last 10 years. Not only pathological and immunohistochemical studies but also the clinical response to therapies reveal that this is the first case of linear psoriasis in Korea.

BACKGROUND: Trichloroacetic acid(TCA) chemical peel has been used for variable skin lesions. However, the effect of TCA chemical peel on acne scars has not been studied. OBJECTIVE: The object of this study is to evaluate the effect of TCA chemical peel on atrop hic acne scars. METHOD: Twenty three patients with atrophic acne scars, who were treated with TCA chemical peel were included. The patieits were interviewed for evaluation of the therapeutic efficacy of TCA chemical peel regarding the number of treatment and satisfaction rates. RESULTS: Those who received treatment for more than 6 times with good or excellent results were 13 out of 15 patients, whereas, those who received treatment for 4 times with good or excellent results were 4 out of 7 patients Thus, chemical peel on acne scars showed that the more often the treatment was carried out, the better the therapeutic effect. There was no significant complication. CONCLUSION: TCA chemical peel is safe and effective for the treatment of atrophic acne scars.

Purpose: To investigate the safety of applying therapeutic contact lenses and eye drops after cataract surgery. Methods: Immediately after cataract surgery, 947 eyes (group 1) used therapeutic contact lenses and eye drops and 914 (group 2) applied antibiotic ointment and wore a gauze eye patch for the first postoperative day. Clinical outcomes including best corrected visual acuity (BCVA), IOP, degree of anterior chamber inflammation, wound leakage, and postoperative endophthalmitis were compared in the two groups 1 day, 1 week, and 1 month after surgery. Results: There were no significant differences in the mean pre- and postoperative BCVA and IOP at 1 day, 1 week, and 1 month between groups 1 and 2. There was no difference in anterior chamber inflammation between the two groups at 1 day (p = 0.302), 1 week (p = 0.437), or 1 month (p = 0.960) after surgery. On the first postoperative day, 10 eyes in group 1 and nine eyes in group 2 had wound leakage (p = 1.000). There was no endophthalmitis in either group. Conclusions The risk of postoperative complications in group 1 was not higher than in group 2. Therefore, wearing therapeutic contact lenses and using eye drops is a relatively safe management method after cataract surgery.

Approximately 1% of all the meningiomas arise from the extradural space. Intradiploic meningiomas constitutes only a very small percentage of this figure. Because of its rarity, it is often confused preoperatively with primary bone tumors of the skull. The intradiploic meningioma of the orbital wall may be considered as a subgroup of intradiploic ectopic meningioma. The following is our report of a recently observed case of intradiploic meningioma of the orbital wall without intracranial or intraorbital involvement. The preoperative tentative diagnosis was osteoma of the orbital wall. Nomenclature and histogenesis of this type of meningioma are discussed.

BACKGROUN: Neointimal hyperplasia is major cause of instent restenosis in coronary artery and stenosis in arteriovenous fisula for hemodialysis. Erythropoietin is known to show proliferative effect on vascular smooth muscle cells in vitro study, but there is few in vivo study. This study investigated the effect of erythropoietin given subcutaneously to injured carotid arteries of rats on neointimal hyperplasia. METHODS: Sprague-Dawley rat underwent common carotid artery (CCA) balloon injury. Erythropoietin was given subcutaneously to balloon-injured rats (n=6) in 100 U/Kg/week by dividing three times. The control group (n=6) was treated with normal saline only. Two weeks later, the lumen and the neointimal area were obtained and compaired. Actively proliferating cells of neointimal area were observed by microscopy using PCNA staining method. RESULTS: Luminal area was 0.233 +/- 0.073 mm2, 0.112 +/- 0.047 mm2 in the control and the erythropoietin treated group respectively. The area was significantly smaller in the treatment group (p<0.05). Neointimal area and neointimal area/medial area ratio were 0.148 +/- 0.029 mm2, 0.226 +/- 0.056 mm2 and 1.169 +/- 0.146 min, 1.953 +/- 0.465 min in the control and the erythropoietin treated group respectively (p<0.05), but no significant difference was observed in medial area between the control and the erythropoietin treated group. Actively proliferating cells of neointimal area were more commonly observed in erythropoietin treated group. CONCLUSION: Erythropoietin increases neointimal cell proliferation in the rat carotid artery injury model. So, erythropoietin treatment may contributes to the development of arteriovenous fistula stenosis caused by neointimal hyperplasia but, further studies are required to elucidate the mechanism and the effect of erythropoietin at various time and dose in neointimal hyperplasia.

We report the case of a 47-year-old man who presented with progressive paraparesis and sphincter changes over 2 weeks. Magnetic resonance imaging revealed a spinal epidural mass from T9 to L2. We performed a decompressive laminectomy and mass removal. The histopathology was consistent with a small lymphocytic lymphoma. No metastatic lesion was noted in the chest and abdomen-pelvic computerized tomography (CT) and positron emission tomography computerized tomography (PET-CT) scan. The final diagnosis was primary spinal lymphoma, so we performed chemotherapy combined with radiotherapy. At one year follow-up, he had no neurological deficit and no recurrence on neurologic and radiologic exams. Primary spinal cord lymphomas should be considered in the differential diagnosis of spinal cord tumors. Early surgical management is mandatory to achieve a recovery of neurologic function, especially if the patient has a neurological deficit.
