Purpose: To evaluate and introduce the technique of C-arm guided aspiration and an injection of a mixture of corticosteroid and local anesthesia for the treatment of calcific tendinitis of the rectus femoris around the hip joint. Materials and Methods: Between March 2003 and May 2005, C-arm guided aspiration and an injection of a mixture of corticosteroid and local anesthesia were performed on 5 patients and a local excision were performed in 1 patient for the treatment of calcific tendinitis of the rectus femoris. The minimum follow-up period was 6 months. The radiology evaluation revealed the presence and size of the calcification. The clinical evaluation involved checking the level of pain relief, range of motion, recurrence, complications. Results: The hip pain improved immediately after treatment. There were no recurrences or complications. Conclusion: The combined treatment of C-arm guided aspiration and an injection of a mixture of corticosteroid and local anesthesia is an effective method for treating calcific tendinitis of the rectus femoris, which can induce rapid symptom relief without any surgical morbidity.

To investigate the effect of tumor removal and administration of OK432 on the splenic natural killer (NK) cell activity in the subcutaneous tumor bearing rats, NK cell activity assay using a 4-hour 51Cr release assay and flow cytometric analysis for NK cell population were performed. The results were as follows: 1. Splenic NK cell activity and population in the subcutaneous tumor bearing rats decreased along with the growth of the tumor. 2. The rats with subcutaneous tumor removal showed decrease of splenic NK cell activity, but splenic NK cell population was not decreased. 3. In the rats with subcutaneous tumor removal and OK432 administration, splenic NK cell activity was significantly increased 1 week after administration of OK432 and then gradually returned to normal, whereas increase of NK cell population was not significant. In the present study, splenic NK cell activity was significantly decreased despite removal of subcutaneous tumor. But with the administration of OK432, splenic NK cell activity returned to normal. Considering the role of NK cells on the first line of defense against the metastatic implantation of circulating tumor emboli, we suggest that perioperative administration of immunopotentiator such as OK432 may improve the patient's outcome after surgery of human neoplasm.

BACKGROUND AND OBJECTIVES: Submandibular space might be estimated as the most common space of deep neck infection. It may, in certain cases, be treated conservatively with no need for early open surgical drainage. The purpose of this study is to review the clinical course and outcome in treatment of submandibular abscess. SUBJECTS AND METHOD: A retrospective study was peformed for 9 years on 49 cases admitted from June 1994 to January 2003 for deep neck infection limited to the submandibular space. All patients were treated with intravenous antibiotics. The conservative group was treated with antibiotics only or combination therapy with needle aspiration. The surgical group was treated with intraoral or external drainage. Contrast enhanced computed tomography (CT) imaging was conducted for all cases and had confirmed that they all had an abscess in the submandibular space. RESULTS: The mean period of hospitalization was 7.6 days, with 35 patients treated with IV antibiotics only and 3 patients with aspiration in the conservative group. On the other hand, 3 patients were treated with intraoral drainage and 8 patients with external drainage in the surgical group. One patient required tracheotomy because of severe dyspnea. There was no complication observed in any cases. CONCLUSION: SSubmandibular abscess is an infection of deep neck space and is considered as the most common infection. Conservative treatment is a good therapeutic choice in cases with localized submandibular absess.

BACKGROUND: Surgical correction of patent ductus arteriosus (PDA) is relatively safe and effective since it does not remain in the category of open-heart-surgery. Although the surgical practice for PDA is performed in almost all hospitals, they contain the problems of anxiety of patients, remained surgical wounds on patients' chests and complications of surgery and general anesthesia. Recently non-surgical methods for the obstruction of PDA have been developed and some of them including buttoned devices are used now. The success rates of these methods approach to 84%. But the problems of embolization, incomplete closure, hemolysis, stenosis of aorta and left pulmonary artery have been reported. We invented new PDA occluder , using stainless steel wire and polyurethane foam. Therefore we investigated the efficacy of occluding blood flow with the new PDA occluder in the vessels of experimental animals. METHOD: Using 304 stainless steel wire which is self-expandable stent, two star-shaped frames were made, each frame forming cone and facing the other's tip. And in the center of the frames polyurethane foam was inserted. 316L stainless steel wire was used to fix the elements described above and some portion of the wire was extracted outside of the frames, shaping hook or round loop with which the occluder could be pulled out in case of misplacement. To create the similar situation to PDA, we made shunts from artery to vein between carotid arteries and jugular veins with surgical bypass grafts or made shunts of direct artery to vein connections without grafts in 4 dogs and 1 pig. Through 8F sheath, we deployed the occluders into the shunts made of 5 grafts or made of 3 arterial ends. Also the occluders were inserted into the femoral artery of dog and iliac artery of pig. After deployment of occluders, angiograms were performed to obscure the efficacy of blocking blood flow and follow-up angiogrms were done in one and two weeks. The animals were sacrificed in one and two weeks to get the tissues including occluders inside. Gross findings were checked about thrombi formation in and around polyurethane foam. RESULTS: The 10 occluders were placed successfully except one site due to misplacement. The occluders successfully blocked the blood flows in all 10 sites within 3 - 60 minutes. Each follow-up angiogram for occluders in one and two weeks revealed good maintenance of blockade in blood flow. Observed gross findings on tissues were packed thrombi formation in the polyurethane foam and membrane formation along the occluder. CONCLUSIONS: This newly developed device revealed good efficacy for occlusion of blood flow including shunts in immediate and follow-up study. Practical method for the delivery of the device and some design modification for proper fitting into the PDA especially for small patients would be required. Longer period of follow-up with more animal experiments for other possible complications including distal embolization would be required also before clinical trial.

OBJECTIVE: To investigate the clinical usefulness of the motor cortex mapping using transcranial magnetic stimulation (TMS) in stroke patients. METHOD: Five stroke patients were studied. A piece of cloth which marked at 1 cm interval was fixed on the patient's head. Motor cortex mapping for abductor pollicis brevis muscles (APB) was performed with a butterfly coil or with a round coil if motor cortex mapping was impossible. RESULTS: Ipsilateral motor pathways were discovered from the unaffected motor cortex to the affected APB in patient 1. This patient showed delayed latency and low amplitude of ipsilateral motor evoked potentials (MEP) that seems to be evoked from the descending motor pathway rather than the corticospinal tract. In patient 2 and 3, contralateral motor pathways traveled from the affected hemisphere to the affected APB. The short latency and high amplitude of MEPs seems to be attributed to the corticospinal tract. In patient 4, no MEP was evoked by any hemisphere or magnetic stimulator. We believe that the affected APB had no motor pathway, and it correlated well with the poor motor function of her hand. In patient 5, contralateral pathways from the affected hemisphere to the affected APB were present. In this patient, the parameters of the motor cortex map such as the amplitude of MEP, the number of MEP evoked site, and the excitatory threshold were improved after 2 months, which correlated well with clinical improvement. CONCLUSION: Motor cortex mapping using TMS is clinically useful for the evaluation of the characteristics of motor pathways and the change of motor cortex excitability in stroke patients.

OBJECTIVE: The goal of our study was to identify and evaluate risk factors for late post-traumatic seizure. METHODS: This study is a retrospective clinical analysis of 52cases of late post-traumatic seizures among 1472 head injury patients treated in our institute from July 1986 to June 1996 and at least followed up over 2 years after head injury. RESULTS: 1) The incidence of late post-traumatic seizure was 3.5% of patients treated for head injury. 2) The factors affecting the incidence of late post-traumatic seizure were initial low Glasgow coma scale(3-8), subdural hematoma, depressed skull fracture(p<0.05). 3) Skull fracture located in temporal area showed higher incidence of late post-traumatic seizure(p<0.05). CONCLUSION: The risk factors for post-traumatic seizure are subdural hematoma, initial low Glasgow coma scale, depressed skull fracture and temporal bone fracture. Both newer antiepileptic drugs and therapies aimed at prevening the brain damage that underlies the development of seizures need to be studied to find an effective way of preventing late post-traumatic seizure through prospective study.

BACKGROUND: The incidence of adenocarcinoma of the lung has been increasing worldwide, and it has been generally been accepted to be relatively unrelated to smoking with a female preponderance. The aim of this study was to examine the gender-related pathological and survival differences in patients with an adenocarcinoma of the lung. MATERIAL AND METHOD: A retrospective review of the clinical information of patients diagnosed with an adenocarcinoma of the lung at Kosin Medical Center from January 1999 to September 2005 was performed. The patient's demographics (age, gender), smoking history, stage, serum tumor marker, pathology classification, EGFR mutation, K-ras mutation, treatment methods, and survival time were analyzed. RESULT: Of the 438 patients, 179 (40.9%) were female. The median age at the diagnosis was 58 years for females and 59 years for males. However, 25.8% of women and only 17.7% of men were under 50 years of age (p=0.02). The distribution of the disease stage was similar in both men and women. The bronchioloalveolar carcinoma component was diagnosed more often in women (11.2%) than in men (5.0%). The overall survival rate was higher in women than in men (p=0.01), and women had a superior therapeutic response to a combined treatment of surgery and chemotherapy. CONCLUSION: This study showed significant genders differences in terms of the smoking history, bronchioloalveolar carcinoma component, overall survival, and survival after combined treatment of surgery and chemotherapy. Therefore, gender differences should be considered when diagnosing and treating adenocarcinomas of the lung.

Anastomotic stenosis of the colon is not an uncommon finding; however, its frequency varies from one study to another. Traditionally, postoperative colonic stenosis is managed surgically. However, endoscopic therapy has recently become the preferred treatment modality over traditional surgery. Good short-term success has been achieved with use of endoscopic balloon dilation; however, restenosis may occur over time in 14% to 25% of patients. The current report showed the effectiveness and usefulness of an insulated-tip knife (IT-knife) for electrocautery therapy of a patient with symptomatic anastomotic colonic stenosis.

OBJECTIVES: In this study, the exposure status of the hazardous substances from incinerators, such as polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs), were studied, and the relationship between the exposure of these hazardous substances and their heath effects on the workers and residents near municipal solid waste (MSW) incinerators and an industrial incinerator investigated. METHODS: Between July 2001 and June 2002, 13 workers at two MSW incinerators, 16 residents from the area around the two MSW incinerators, 6 residents from the control area, and further 10 residents near an industrial incinerator, estimated to emit higher levels of hazardous substances, were interviewed. Information, including sociodemographic information, personal habits, and work history, detailed gynecologic and other medical history were collected through interviews. Blood samples were also collected from 45 subjects, and analyzed for PCDD/DFs, by high resolution gas chromatography - high resolution mass spectrometry, using the US EPA 1613 method. In addition to the questionnaire survey, urinary concentrations of 8-hydroxydeoxyguanosine (8-OH-dG) and malondialdehyde (MDA) were measured as oxidative injury biomarkers. The urinary concentrations of 8-OH-dG were determined by in vitro ELISA, and the MDA by HPLC, using an adduct with thiobarbituric acid. RESULTS: The PCDD/DFs concentrations in the residents near the industrial incinerator were higher than those in the controls, workers and residents near the MSW incinerators. The average TEQ (Toxic Equivalencies) concentrations of the PCDD/DFs in residents near the industrial incinerator were 53.4pg I-TEQs/g lipid. The estimated daily intakes were within the tolerable daily intake range (1-4 pg I-TEQ/Kg bw/day) suggested by WHO (1997) in only 30% to the people near the industrial incinerator. Animal studies have already shown that even a low body burden of PCDD/DFs, such as 10ng TEQ/kg bw, can cause oxidative damage in laboratory animals. Our study also showed that the same body burden of PCDD/DFs can cause oxidative damage to humans. CONCLUSIONS: The exposures to PCDD/DFs and the oxidative stress of residents near the industrial incinerator, were higher than those in the controls, workers and residents near the MSW incinerators. Proper protection strategies against these hazardous chemicals are needed. Because a lower body burden of PCDD/Fs, such as 10ng TEQ/kg bw, can cause oxidative damage, the tolerable daily intake range should be restrictedly limited to 1pg I-TEQ/kg bw/day.

Bisphosphonates have been approved for Paget's disease, cancer - related hypercalcemia, bone involvement in multiple myeloma or solid tumors and osteoporosis. Although, underlying pathophysiological mechanisms remain unclear, it seems that bisphosphonates inhibit osteoclast precursor cells, modulate migratory and adhesive characteristics and induce apoptosis of osteoclasts. Furthermore impacts on angiogenesis, microenvironment and signal transduction between osteoclasts and osteoblasts. In this report, we present a case of oral bisphosphonates induced osteonecrosis of the mandible in a 84-year-old patient who received for two years. Two tapered screw vent implants(Zimmer, USA) were placed in the area of first and second molar. Two weeks later after crowns restored, some inflammatory signs and symptoms were observed on the second molar area. Sequestrum was formed and the sequestrum was removed with the implant. Frequent follow-up checks and oral hygiene maintenances were done and the first molar implant was restored. There is insufficient evidence suggests that duration of oral bisphosphonate therapy correlates with the development and severity of osteonecrosis. Therefore, dentists should not overlook the possibility of development of bisphosphonate induced osteonecrosis in patients who have taken oral forms of medication for less than three years.
