Tracheal bronchus is an aberrant, accessory or ectopic bronchus arising almost invariably from the right lateral wall of the trachea and may be related to inflammatory conditions affecting the lung, including recurrent pneumonia, bronchiectasis. Recently we experienced a case of tracheal bronchus associated with pulmonary actinomycosis. The 37-year-old male patient had suffered recurrent hemoptysis and had been medicated as a presumptive diagnosis of tuberculosis, but either clinical or radiologic improvement was not seen. Right upper lobectomy was performed and pulmonary actinomycosis was confirmed by the histologic examination. Postoperatively, the patient was medicated with penicillin and ampicillin for 3 months and completely recovered without any evidence of recurrence during the 6month follow-up period.

Echinostomiasis is an endemic intestinal trematodiasis of humans in Korea We observed a human case of Echinostomn honense infection who had ulcerations on the duodenal mucosa. A 55-year old man living in Hamyang-gun, Kyongnam, complained of epigastric pain with hematemesis In April 1994. Endoscopy revealed lesions of early gastric cancer and duodenal ulcerations. A penetrating parasite into the duodenal mucosa was picked out, and identified as E. honense. As the patient was treated 10 praziquantel 10 mg/kg single dose,3 more E. hofene and 7 Metogonimw worms were recovered. This case demonstrates that echinostomiasis causes gross ulcerations in the duodenum.

Unilateral hydrocephalus is an uncommon disease which may result from obstruction of the foramen of Monro. Congenital or acquired lesions obstructing this foramen have been reported. We present a case of prenatally diagnosed fetal unilateral hydrocephalus. Ventriculoperitoneal shunt operation was performed and following the procedure, ventricular size was decreased and patients neurological status was improved.

The radiographic findings of an osteolytic lesion in the knee may indicate numerous possible impressions. Furthermore, osteolysis is a possible cause if there is a surgical history of total knee arthroplasty (TKA). The authors diagnosed osteolysis of the fibular head after aseptic loosening of the tibial component of a cemented TKA in an 83-year-old female patient who visited with right knee pain and report their treatment with revision TKA along with a literature review.

The clinical manifestation of pericardial disease is similar to that of coronary artery disease and aortic disease. Therefore, a timely and accurate diagnosis is necessary. The pericardium is a 2-layered membrane that envelops the heart and great vessels, and there are numerous anatomic variations and pathologic conditions. Large or unusually located pericardial recesses can be easily mistaken for abnormal findings. Additionally, primary pericardial diseases resulting from infections, tumors, and injuries are possible; further, diseases can quickly spread along the pericardium. Echocardiography is generally the first imaging tool used to evaluate the pericardium. However, it has limited windows and poor resolution. Besides, the evaluation of postoperative echocardiography is sometimes limited. Currently, CT and MR imaging are useful for evaluating pericardial diseases. Detailed knowledge of the pericardium is important for interpreting the images and clinical results.

Bacillus species are aerobic, gram-positive, spore forming rods, and they are usually found in the surrounding environment. If they are isolated in the clinical specimen, they are generally considered as contaminants rather than a true pathogen. Infection with Bacillus licheniformis is usually associated with the immunocompromised state, trauma, an indwelling intravenous catheter or an intravenous drug abuser. This infection is easily controlled by removal of the catheter and surgical debridement of the local infected tissue as well as an appropriate antimicrobial therapy. We reported here on a case of Bacillus licheniformis bacteremia associated with a bronchoscopic procedure in an immune competent patient.

Advancement of imaging and surgical technique makes the internal hemipelvectomy one of the routine procedures of pelvis sarcoma. However, optimal reconstructive option for skeletal defect is still controversial. Pasteurized autogenous bone-total hip composite is a biologic method and its anatomical appropriateness gives good indication for selected cases. Nevertheless, in case of complication such as infection or mechanical breakage, removal of hardware including graft is inevitable. In those cases, marked limb length discrepancy induce marked functional deficit. To overcome this problem, the authors report 1 case, refining previous technique, saving the femoral head and reinsertion of osteoarticularly pasteurized host bone.

This is a case report of correction of malunioned maxilla after traffic accident by Le Fort I osteotomy and posterior segmental osteotomy. By this procedure, authors obtained the following results. 1. The malinioned maxilla after traffic accident which had anterior crossbite, posterior open bite and scissor's bite were corrected by Le Fort I osteotomy and posterior segmental osteotomy. 2. No postoperative infection and specific complication were seen in this case. 3. Postoperative intermaxillary fixation was maintained for 8 weeks. And then, the patient could open his mouth in normal range after a week of intermaxillary fixation removal. 4. For rigid fixation and reducing relapse, the osteotomized maxilla was fixed with miniplates.

The heel, with its specialized fat for shock absorption at heel strike and large surface area for balance and weight bearing, is a important component of normal ambulation. Despite of distinguished improvement in the field of microsurgical free flaps, the choice of reconstruction of the heel has been remained controversial. We reviewed 22 cases of the heel reconstruction using vascularized free flaps from January, 1980 through May, 1993 at the Department of Orthopedic Surgery of Korea University Hospital. The results were as follows: 1. The etiology was traumatic in 21 cases, and chronic ulceration due to burn in 1. 2. The arteries used in free flaps were 11 dorsalis pedis arteries, 2 deep circumflex iliac arteries, 2 supeficial iliac arteries, 2 branches of lateral femoral circumflex iliac arteries, 2 radial arteries, and 3 thorcodorsal arteries. 3. The mean size of the vascularized bone was $4.5cm{\times}3.5cm$, and that of skin flap was $12.1cm{\times}9.2cm$. 4. Of the 22 cases, 19 had a successful outcome and 3 in failure, the causes of failure were thrombosis and infection.

Purpose: To evaluate and report the clinical and radiological outcomes of open reduction and internal fixation with a mini-T plate for unstable distal clavicle fractures. Materials and Methods: From December 2004 to July 2007, fifteen patients who had a fracture of the distal clavicle (Neer type II fracture) were treated with an open reduction and internal fixation using a mini-T plate. They were followed up for a minimum of one year and the clinical and radiological results were analyzed. Results: The average time to fracture union was 3.1(3~4) months. There were no complications, such as deep infection or fixation loss. The mean ASES score was 97 points (85~100points) at the last follow up period, and 14 patients had a full range of motion of the shoulder. Conclusion: Open reduction and internal fixation with a mini-T plate for unstable distal clavicle fracture is a good surgical method with good clinical and radiological results.
