Purpose: Retronychia is the embedding of the nail into proximal nail fold. Retronychia starts with disruption of the longitudinal growth of the nail. With the growth of a new nail, the old one is pushed upwards and backwards. This leads to embedding of the top nail into the ventral aspect of the proximal nail fold and results with chronic paronychia. We present a case of retronychia that was rarely reported in the literature. Methods: A 46-year old female presented with a 3-month history of painful right first, 2nd, 3rd toenail changes. Although she was initially treated with broad spectrum antibiotics, she did not response to therapy. Later, she presented to our department because of progressively worsening pain that impaired her walking. Physical examination revealed with proximal nail fold erythema, painful swelling, yellowish nail discoloration, and distal onycholysis. Bacterial and fungus culture showed no organism. Treatment was surgical nail avulsion under local anesthesia. Results: The postoperative course was uneventful. 10 months later, the patient had a normal growing nail and was free of symptoms. Conclusion: We report a case of retronychia on toenail. Retronychia is a proximal nail plate ingrowth into the proximal nail fold which is associated with multiple generations of nail plate misaligned beneath the proximal nail. Management consisted of simple avulsion of superimposed nail. Retronychia is suspected with a persistent paronychia, particularly in the setting of trauma. Avulsion of the top nail confirms the diagnosis and may be curative if the underlying nail appears healthy.

Purpose: Intramuscular stimulation (IMS) shows good results in the treatment of chronic pain patients who did not respond to other treatments such as oral analgesics, trigger point injection, nerve block and epidural steroid injection. But, IMS procedure especially, patients with diabetes mellitus (DM) has sometimes serious problem. So, we present a very rare case of intramuscular abscess in the sternocleiomastoid muscle after IMS with literature review. Methods: A 66 year old male visited our department 7 days after IMS in the neck. His premorbid conditions and risk factors of deep neck infection was DM and old age. Computed tomographic scans of the head and neck region were performed in this patient: signs of deep neck infection, were seen enhanced abscess in the sternocleidomastoid muscle, cellulitis overlying tissue of the neck, and air bubbles involved muscle. Necrotic wound was excised serially and we treated this with the Vacuum-assisted closure (VAC, Kinetics Concepts International, San Antonio, Texas) system device. After appropriately shaping the sponge in the pockets, continuous negative pressure of 125 mmHg was applied. The VAC therapy was utilized for a period of 12 days. Results: We obtained satisfactory results from wide excision, drainage of the abscess with the VAC system, and then primary closure. The postoperative course was uneventful. Results: We suggest that many of the infectious complications may be preventable by strict adherence to aseptic techniques and that some of the other complications may be minimized by refining the techniques with a clear understanding of the medical disorders of patients. And, the refined technique using the VAC system can provide a means of simple and effective management for the cervical intramuscular abscess, with better cosmetic and functional results.

Takayasu's arteritis is a chronic inflammatory disease of unknown cause. It predominantly affects the aortic arch and its branches. Concomitant involvement of coronary and renal arteries is a rare entity. In this report, we described successful treatment of a patient with Takayasu's arteritis associated with coronary and renal arteries stenosis. A 23-year-old woman was presented with chest pain on exertion. Angiographic studies demonstrated left main coronary, bilateral renal, and left subclavian arteries stenosis. She underwent angioplasty and stenting of bilateral renal artery. After one week, coronary artery bypass grafting using greater saphenous veins and aorto-subclavian bypass with PTFE vascular graft were done simultaneously. She was discharged on the 13th postoperative day without any complications.

Purpose: To evaluate clinical features of ankle lesions, associated with anterior soft tissue impingement. Materials and Methods: We retrospectively reviewed 21 patients who had chronic anterior ankle pain as initial symptom and associated ankle lesions with anterior soft tissue impingement. Based on preoperative radiologic findings, physical examination intra-operative findings, appropriate procedures were done for lesions by either arthroscopic or minimal open procedure or combined. Clinical evaluation was done using American Orthopedic Foot and Ankle Society, ankle-hind foot score (AOFAS score) and visual analog scale (VAS) on last follow up. Results: Associated lesion(s) to anterior soft tissue impingement of the ankle were 16 cases of osteochondral lesion of talus, 14 cases of bony impingement, 6 cases of ankle lateral instability, 5 cases of loose body, 4 cases of os subfibulare. AOFAS score was $58.9\;{\pm}\;5.1$ preoperatively and $74\;{\pm}\;9.1$ on last follow up. Clinical satisfaction score using VAS showed excellent in 3 cases, good in 11, fair in 3, poor in 4. Conclusion: The patients who had anterior soft tissue impingement would have various associated lesions on their ankle. In such cases, preoperative counseling for variety of postoperative results would be needed.

Blunt abdominal trauma is commonly encountered in the emergency department. The lack of historical data and the presence of distracting injuries or altered mental status, from head injury or intoxication, can make these injuries difficult to diagnose and manage. We experienced a case of traumatic organized hematoma misdiagnosed as intra-peritoneal tumor with intestinal obstruction. A 52-year-old homeless male patient who have chronic alcoholism was admitted via emergency room with infra-umbilical abdominal pain. At admission, he was drunken status and so we could not be aware of blows to the abdomen. He had a unknown large operation scar on mid abdomen. A computed tomography (CT) scan showed the intestinal obstruction of the ileum level with 5.5cm sized mesenteric tumor. We performed adhesiolysis and widely segmental resection of small bowel including tumor with side-to-side anastomosis due to great discrepancy in size. He stated later that he was a victim of the violence before 3 weeks. A final pathologic report revealed well encapsulated, traumatic mesenteric hematoma with organizing thrombi, ischemia and abscess formation with multiple adhesion bands. Finally, the patient was discharged without complications on postoperative day 14.

A 67 years old male patient was admitted with back pain that had recurred from 6 months previously. Eleven years previously, he underwent stent grafting at the descending thoracic aorta for a chronic Stanford type B aortic dissection. The preoperative computed tomography showed aortic dissection from the origin of the left subclavian artery to the bifurcation of the abdominal aorta, and there was a type I endoleak at the proximal portion of the stent graft and aneurysmal dilatation of the descending aorta. A hybrid endovascular repair was successfully performed, and this involved debranching and rerouting the aortic arch vessels under extracorporeal cardiopulmonary bypass and then this was followed 13 days later by stenting in the ascending aorta, the aortic arch and the descending aorta. The postoperative computed tomography showed complete exclusion of the type I endoleak. After discharge, he has been followed up for 8 months without any problems.

Purpose: Subtalar arthrodesis has been the gold standard for the painful subtalar joint disorders. Successful subtalar arthrodesis requires fusion of the 3 facet joints. The purpose of the study is to compare the clinical outcome of the posterior fixation (P2) and anterior-posterior (A1P1) fixation technique for subtalar arthrodesis which enhance anterior and middle facet fixation. Materials and Methods: The study is based on the 20 feet (19 patients) of the subtalar arthrodesis utilizing cannulated screws from September 2006 to September 2009 with at least 1-year follow-up. Two fixation techniques were utilized for the subtalar arthrodesis: 1) posterior fixation only (P2, 7 feet, 35%) and 2) anterior-posterior (A1P1) fixation method (13 feet, 65%). Visual Analog Scale Pain (VAS) score, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score (maximum: 94 points), the time for returning to daily living and the patient satisfaction were also evaluated. Results: Average follow-up period were 13.2 months (12-3 mo). The AOFAS score improved from preoperative average 45 (0-68) to 81.6 (62-94), while VAS score was decreased from average 8.0 (3-10) to 1.8 (0-5) at final follow-up. Ninety-five percent of the patients were satisfied with surgery. All the patients returned to daily living at average 7.2 months (2-15 mo) post-surgery. Radiographically, 2 techniques both showed 100% fusion of the posterior compartment of the subtalar joint. Postoperative complications were 1 case of low grade infection and 1 case of sural nerve neuralgia. Conclusion: The subtalar arthrodesis using A1P1 fixation technique showed better fusion rate of the anterior compartment of the subtalar joint compared to P2 fixation technique although the 2 techniques both showed similar favorable clinical outcome. Therefore the A1P1 fixation technique is found to be a viable option to address chronic painful subtalar joint disorders to enhance the anterior compartment fixation.

Purpose: Cervical necrotizing fasciitis tends to involve the deep soft tissues and spread caudally to the anterior chest and mediastinum, often resulting in major complications and death. It may rapidly spread into the thorax along fascial planes, and the associated diagnostic delay results in this descending necrotizing mediastinitis. So, aggressive multidisciplinary therapy with surgical drainage is mandatory. We present a very rare case of descending necrotizing mediastinitis with literature review. Methods: A 53 years old male visited our department 7 days after trauma in neck. His premorbid conditions and risk factors of necrotizing fasciitis were concealed hepatoma, trauma history, chronic liver disease, and nutrition deficit. Computed tomographic scans of the head and neck region were performed in this patient : signs of necrotizing fasciitis, were seen in the platysma, sternocleidomastoid, trapezius muscle and strap muscles of the neck. Fluid accumulations involved multiple neck spaces and mediastinum. At the time, he diagnosed as necrotizing fasciitis on his neck and anterior chest. Necrotic wound was excised serially and we treated this with the Vacuum - assisted closure(VAC, Kinetics Concepts International, San Antonio, Texas) system device. After appropriately shaping the sponge and achieving additional 3 pieces drainage tubes in the pockets, continuous negative pressure of 125 mmHg was applied. The VAC therapy was utilized for a period of 12 days. Results: We obtained satisfactory results from wide excision, abscess drainage with the VAC system, and then split thickness skin graft. The postoperative course was uneventful. Conclusion: The refined technique using the VAC system can provide a means of simple and effective management for the descending necrotizing mediastinitis, with better cosmetic and functional results. Finally, the VAC system has been adopted as the standard treatment for deep cervical and mediastinal wound infections as a result of the excellent clinical outcome.

Background: Off-pump coronary artery bypass grafting (OPCAB) shows fewer side effects than cardiopulmonary by. pass, and other benefits include myocardial protection, pulmonary and renal protection, coagulation, inflammation, and cognitive function. We analyzed the clinical results of our cases of OPCAB. Material and Method: From May 1999 to August 2007, OPCAB was performed in 100 patients out of a total of 310 coronary artery bypass surgeries. There were 63 males and 37 females, from 29 to 82 years old, with a mean age of $62{\pm}10$ years. The preoperative diagnoses were unstable angina in 77 cases, stable angina in 16, and acute myocardial infarction in 7. The associated diseases were hypertension in 48 cases, diabetes in 42, chronic renal failure in 10, carotid artery disease in 6, and chronic obstructive pulmonary disease in 5. The preoperative cardiac ejection fraction ranged from 26% to 74% (mean $56.7{\pm}11.6%$). Preoperative angiograms showed three-vessel disease in 47 cases, two-vessel disease in 25, one-vessel disease in 24, and left main disease in 23. The internal thoracic artery was harvested by the pedicled technique through a median sternotomy in 97 cases. The radial artery and greater saphenous vein were harvested in 70 and 45 cases, respectively (endoscopic harvest in 53 and 41 cases, respectively). Result: The mean number of grafts was $2.7{\pm}1.2$ per patient, with grafts sourced from the unilateral internal thoracic artery in 95 (95%) cases, the radial artery in 62, the greater saphenous vein in 39, and the bilateral internal thoracic artery in 2. Sequential anastomoses were performed in 46 cases. The anastomosed vessels were the left anterior descending artery in 97 cases, the obtuse marginal branch in 63, the diagonal branch in 53, the right coronary artery in 30, the intermediate branch in 11, the posterior descending artery in 9 and the posterior lateral branch in 3. The conversion to cardiopulmonary bypass occurred in 4 cases. Graft patency was checked before discharge by coronary angiography or multi-slice coronary CT angiography in 72 cases, with a patency rate of 92.9% (184/198). There was one case of mortality due to sepsis. Postoperative arrhythmias or myocardial in-farctions were not observed. Postoperative complications were a cerebral stroke in 1 case and wound infection in 1. The mean time of respirator care was $20{\pm}35$ hours and the mean duration of stay in the intensive care unit was $68{\pm}47$ hours. The mean amounts of blood transfusion were $4.0{\pm}2.6$ packs/patient. Conclusion: We found good clinical outcomes after OPCAB, and suggest that OPCAB could be used to expand the use of coronary artery bypass grafting.

Background: Intralobar and extralobar pulmonary sequestrations have been considered as congenital lesions that occur at different stages of embryonic life. However, most cases of intralobar pulmonary sequestration (IPS) seem to have an acquired origin, as they are absent in infants and associated anomalies are relatively, uncommon among them. Material and Method: The cases of 25 patients who were diagnosed as IPS after surgical resection from December, 1985 to July, 2002 were included in this study. The medical records wire retrospectively reviewed and the clinical characteristics were age at operation; gender; symptoms at presentation; presence of congenital anomalies; combined diseases; preoperative studies and diagnosis; location of the lesion; method of surgical resection; origin, size and numbers of aberrant artery; histopathological findings; and postoperative complications. Result: There were 17 (68%) female patients and 8 (32%) male patients, their ages ranged from 1 to 57 and mean value was 23 years old. Though 14 patients (56%) complained of respiratory symptoms such as pneumonia and recurrent respiratory infections, a large number of patients (44%) were asymptomatic or had chest pain only when the lesion was discovered. Only 8 patients (32%) were diagnosed as pulmonary sequestration preoperatively and 8 (32%) were suspected as mediastinal or lung tumor, 5 (20%) were congenital or acquired cystic lung disease, and 4 (16%) were lung abscess or bronchiectasis, respectively. The majority of aberrant arteries (86.4%) confirmed during the operation were originated from thoracic aorta and 2 were thoracic and abdominal aorta, 1 was abdominal aorta, respectively. The younger patients (less than 10 years old) had more other congenital anomalies (30% vs 6.7%) but the proportion of congenital IPS was not significantly different (10% vs 6.7%, p>0.05) compared with elder patients. Histopathologically, almost all lesions showed chronic inflammation, cystic changes and similar pleural adhesions regardless of age. Conclusion: The large portion of the patients with IPS (44%) was clinically asymptomatic or presented non-respiratory symptoms at diagnosis and likely to be diagnosed as mediastinal or lung tumor especially in elder patients. Though the younger patients had more other congenital anomalies, most cases of IPS proved to be acquired lesions in terms of the histopathlogical findings and the proportion of congenital evidences.
