Tuberculous aneurysm of the aorta is exceedingly rare. To date, the standard therapy for mycotic aneurysm of the abdominal aorta has been surgery involving in-situ graft placement or extra-anatomic bypass surgery followed by effective anti-tuberculous medication. Only recently has the use of a stent graft in the treat-ment of tuberculous aortic aneurysm been described in the literature. We report two cases in which a tuberculous aneurysm of the abdominal aorta was success-fully repaired using endovascular stent grafts. One case involved is a 42-year-old woman with a large suprarenal abdominal aortic aneurysm and a right psoas abscess, and the other, a 41-year-old man in whom an abdominal aortic aneurysm ruptured during surgical drainage of a psoas abscess.

The incidence of tuberculosis (Tbc) infection is high in some parts of the world and tuberculous cold abscess of the chest wall (CACW) often fails to respond to medical treatment. Medical records of 178 patients who underwent surgical treatment of chest wall abscesses from July 1970 to Sept. 2000 were reviewed and 89 patients who were pathologically confirmed as Tbc cold abscess cases were included in this study. Their ages ranged from 9 to 71 years (mean 33.3 years) and the male to female ratio was 1.2:1 (49 male, 40 female). The symptoms were palpable chest wall mass, pain and pus discharge, and three patients had multiple lesions. Twenty-five patients (28%) underwent excision of chest wall abscesses and 64 patients (72%) underwent chest wall and rib resection. Tbc medication was given preoperatively in 39 patients for an average of 6.3 months and all patients were given Tbc medication postoperatively for an average of 12 months. Postoperative complications were bleeding, pus discharge, empyema, pleural effusion, wound dehiscence, subcutaneous emphysema and activation of pulmonary Tbc. The disease recurred in 7 patients (7.8%) and these 7 patients all underwent a second operation. We recommend preoperative Tbc medication and complete resection of chest wall abscesses including any suspicious ribs. Postoperative Tbc medication for a minimum of 12 months is essential to decrease the risk of a relapse.

PURPOSE: The aim of this study was to review our experience with splenic abscesses, with respect to the relevant aspects of splenic abscesses and treatment outcomes. MATERIALS AND METHODS: We reviewed the cases of 18 patients who had splenic abscesses and who were treated at our hospital from November 1993 to December 2008. RESULTS: The most common symptom at presentation was abdominal pain in 12 patients (66.7%). The median duration from symptom onset until establishment of a diagnosis was 22 days. Streptococcus viridians was the most common pathogen (27.8%), follow by Klebsiella pneumoniae (22.2%). The mortality rate during the inpatient period and the previous 90 days was 16.6%. Three of four patients with Klebsiella pneumoniae showed a single abscess pocket. Four patients (22.2%) underwent percutaneous drainage, eight (44.5%) recieved antibiotic treatment only and six (33.3%) underwent splenectomy. CONCLUSION: There is no gold standard for treating splenic abscesses. Treatment should be customized for each patient.

A psoas abscess (PA) is a rare clinical entity but is potentially serious condition which presents diagnostic and therapeutic challenges. The diagnosis is frequently delayed due to its variable and nonspecific features and occult clinical course. The delay in diagnosis and treatment of PA is the major poor prognostic factor. We describe herein a case of the sterile psoas abscess complicating Cronh's disease which presented as hip flexion contracture. A 29-year-old man, at remission stage of CD involving ileocolic segment, was admitted due to pain from hip contracture. He had no bloody diarrhea and no abdominal pain. PA was confirmed by abdominal ultrasound. PA with hip contracture was completely treated with surgical excision, irrigation, drainage, and antibiotics. PA was sterile and there was no evidence of a fistulous communication from the bowel. Once suspected, aggressive diagnostic work up and definitive operative intervention is needed.

Infections of the oral and maxillofacial region are one of the most common conditions for which a patient presents to a maxillofacial surgeons. Although these infections can arise from a variety of source, dental disease is the most common etiology. So, odontogenic infection are frequently encountered in the practice of oral and maxillofacial surgery. These infections often respond to antimicrobial chemotherapy or surgical intervention, such as extraction of teeth, incision and drainage through clinical features. But, odontogenic infections have the potential to spread via the fascial spaces in the head and neck region, and, they spread to cavernous sinus, deep musculofascial space and other vital structure. We have undertaken clinical studies on infections in the oral and maxillofacial regions by analyzing retrospectively hospitalized patients in the Department of Oral and Maxillofacial Surgery, Chonbuk National University Hospital past 5 years from 2000 to 2004. And, the patients'age, sex, medical history, causes of the infection, surgical intervention, and other clinical parameters were reviewed. The obtained results were as follows: 1. The most frequent cause of oral and maxillofacial infection was odontogenic. And in the odontogenic cause, dental caries was the most common cause (47.2%). 2. The most common fascial space involved was the submandibular space (15.7%), followed by the buccal space (14.8%). 3. 60.4% of all patients required surgical drainage of the abscess, endodontic treatment or tooth extraction or periodontal treatment with drainage. 4. The most causative organism isolated from the pus culture were streptococcus viridans (53.9%). 5. Underlying medical problems were found in 136 patients (41.9%), the most common being hypertension (27.9%) and diabetes (14.7%).

Transarterial chemoembolization (TACE) is one of the most effective therapies for unresectable hepatocelluar carcinoma or metastatic hypervascular tumors. Abscess occurring in the other organs beside the liver after TACE is a complication that often occurs, sometimes potentially fatal. We report a case of spinal epidural abscess occurred after liver abscess complicated by TACE in a patient with metastatic neuroendocrine tumors to the liver. A 67-year-old female underwent TACE first for the metastatic lesions to liver, with a history of pancreatoduodenectomy for the primary pancreatic neuroendocrine tumor. Four days after TACE, sudden high fever occurred, and liver abscess was found on abdominal CT. Two days later, back pain and radiating pain to the right leg occurred, and lumbar spine MRI showed spinal epidural abscess. After intravenous antibiotics for 8 weeks and partial laminectomy, the patient recovered and was discharged without complications.

INTRODUCTIONKlebsiella pneumoniae septic arthritis and osteomyelitis, albeit uncommon in adults, are important sites of disseminated infection. Many case reports have shown K. pneumoniae as a cause of nosocomial transmitted septic arthritis in neonates and children. We report a rare case of an elderly patient with K. pneumoniae genitourinary infection spreading to the liver and other extra hepatic sites like the prostate and peripheral joint.

CLINICAL PICTUREThe patient presented with a short history of general malaise, fever and urinary symptoms, associated with an acute monoarthritis of the ankle. On admission, he was in septic shock. Investigations suggested an infective cause, as evidenced by raised total white cell count and pyuria. K. pneumoniae was cultured from both urine and ankle synovial fluid. Imaging confirmed multiple liver and prostatic abscesses, as well as osteomyelitis of the foot bones adjacent to the ankle.

TREATMENTTreatment in this case included surgical drainage of the affected joint and surrounding soft tissue structures, in addition to a 6-week course of systemic antibiotics.

OUTCOMEThe patient had good clinical response following treatment. In addition, we noted a normalisation of his laboratory parameters and resolution of the intraabdominal and pelvic abscesses.

CONCLUSIONThis case emphasises the importance of timely and accurate diagnosis followed by appropriate treatment in disseminated K. pneumoniae infection to prevent significant morbidity and mortality.

OBJECTIVETo analyze the major complications of percutaneous cooled-tip microwave ablation for the treatment of primary liver cancer and the possible risk factors of severe complications in a series of 693 patients.

METHODSThe clinicopathological data of 693 patients with primary liver cancer who underwent ultrasound-guided percutaneous cooled-tip microwave (MW) ablation in our hospital over the past 5 years were retrospectively analyzed, and the risk factors of severe complications were explored.

RESULTSIn a total of 693 patients with 898 primary liver tumors were treated and 1111 MW ablation sessions were performed. The mean diameter of tumors was (2.5 ± 1.2) cm and the range was 0.4 - 10.0 cm. Three deaths occurred in the peri-ablation period, including one case died of multiorgan failure, one case died of pulmonary embolism and one case died of hepatorenal syndrome. Major complications occurred in 27 (3.9%) patients, including 12 pleural effusion requiring thoracentesis (1.7%), 10 tumor seeding (1.4%), 3 liver abscess and empyema (0.4%), 1 hemorrhage requiring arterial embolization (0.1%), and 1 bile duct injury (0.1%). The Chi-square test results showed that the diameter of tumors, number of MW ablation sessions and histological type of tumor were significantly associated with the major complications rate (P < 0.05). The multiple variables 1ogistic regression analysis showed that only type of tumors was associated with the major complication rate (P < 0.05).

CONCLUSIONSResults of this study confirm that cooled-tip MW ablation is a relatively low-risk and effective minimally invasive procedure for the treatment of primary liver cancer. Proper direction for the treatment of cholangiocarcinoma (ICC) patients as well as fewer ablated tumor numbers during one hospital stay may help minimize the major complication rate in patients with primary liver cancer treated by ultrasound-guided percutaneous cooled-tip microwave ablation.

BACKGROUND: The number of immunocompromised hosts has been increasing steadily and a new pulmonary infiltrate in these patients a potentially lethal condition which needs rapid diagnosis and treatment. In this study we sought to examine the clinical manifestations, radiologic findings, and therapeutic outcomes of pulmonary mycoses presenting as a new pulmonary infilrate in immunocompromised hosts. METHOD: All cases presenting as a new pulmonary infilrate in immunocompromised hosts and confirmed to be pulmonary mycoses by pathologic examination or by positive culture from a sterile site between October of 1996 and April of 1998 were included in the study and their chart and radiologic findings were retrospectively reviewed. RESULTS: In all, 14 cases of pulmonary mycoses from 13 patients(male : female ratio = 8 : 5, median age 47yr) were found. Twelve cases were diagnosed as aspergillosis while two were diagnosed as mucormycosis. Major risk factors for fungal infections were chemotherapy for hematologic malignancy (10 cases) and organ transplant recipients(4 cases). Three cases were receiving empirical amphotericin B at the time of appearance of new lung infiltrates. Cases in the hematogic malignancy group had more prominent symptoms : fever(9/10), cough(6/10), sputum(5/10), dyspnea(4/10), chest pain(5/10). Patients in the organ transplant group had minimal symptoms(p<0.05). On simple chest films, all of the cases presented as single or multiple nodules (6/14) or consolidations(8/14). High resolution computed tomograph showed peri-lesional ground glass opacities(14/14), pleural effusions(5/14), and cavitary changes(7/14). Definitive diagnostic methods were as follows : 10 cases underwent minithoracotomy, 2 underwent video-assisted thoracoscopic surgery, 1 underwent percutaneous needle aspiration and 1 case was diagnosed by culture of abscess fluid. All cases received treatment with amphotericin B with 1 case each being treated with liposomal amphotericin B and itraconazole due to renal toxicity. Lung lesion improved in 12 of 14 patient but 4 patients died before completing therapy. CONCLUSION: When a new lung infiltrate develops presenting either as a nodule or consolidation in a neutropenic patient with hematologic malignancy or in a transplant recipient, you should always consider pulmonary mycoses as one of the differential diagnosis. By performing aggressive work up and early treatment, we may improve prognosis of these patients.

Lactococcus lactis cremoris infections are very rare in humans. We experienced liver abscess and empyema due to L. lactis cremoris in an immunocompetent adult. A 42-yr-old man was admitted with fever and abdominal pain. Abdominal computed tomography (CT) revealed a liver abscess and chest CT showed loculated pleural effusion consistent with empyema. L. lactis cremoris was isolated from culture of the abscess material and blood. The patient was treated with pus drainage from liver abscess, video-assisted thoracoscopic decortications for empyema, and antibiotics including cefotaxime and levofloxacin. The patient was completely recovered with the treatment. To our knowledge, this is the first report of a L. lactis cremoris infection in Korea.
