OBJECTIVE: Internal carotid artery (ICA) trunk aneurysms are rare constituting about 0.9 to 6.5% of all ICA aneurysms. They may arise from medial, lateral, ventral (posterior) or dorsal (anterior) walls of ICA. The most frequent site of origin is dorsomedial, followed by dorsal, dorsolateral and ventromedial wall. ICA dorsal wall aneurysms can be divided into the saccular type and blister type, which have different shapes, wall histological features and surgical tactics. The authors report an analysis of 27 cases of ICA trunk aneurysms treated with surgical clipping or GDC embolization. METHODS: Of 145 cases of ICA aneurysms from May 1998 to December 2005, we found 27 cases (17.5%) of such unusual aneurysms located at nonbranching sites of the intradural ICA. Features of neuroimagings and medical records were analyzed. RESULTS: Out of 27 aneurysms, 10 were located at ICA dorsal wall, 8 aneurysms were developed at ICA medialwall. Seven aneurysms originated from ICA ventral wall. Seven cases presented with subarachnoid hemorrhage and 20 cases were found unruptured. Two patients had blister-like aneurysm, and the others had saccular aneurysms. All patients were treated successfully with microsurgical clippings or GDC embolization. Microsurgical clipping were performed in 14 cases and among them, removal of anterior clinoid process was done in 12 cases. Eleven aneurysms were occluded with detachabel coil. Two patients underwent balloon occlusion of ICA. Blister aneurysm was clipped including a portion of the normal ICA wall. Good outcomes were obtained in 25 patients, and two patients were dead. CONCLUSION: ICA trunk aneurysms are developed at any site of ICA circumference. Therefore we consider a variety of treatment strategies. On clipping of aneurysms at proximal ICA trunk, removal of anterior clinoid process is important. Endovascular treatment may be good an alternative. However, surgical treatment is essential for blister like aneurysms.

Injuries and pains of musculoskeletal joint in human body is common onset in industrialized world. However, muscle fatigue plays a very significant role in contributing causes of many pains associated with musculoskeletal joints. Based on this hypothesis, degree of muscle fatigue was investigated using electromyography measurement technique during isometric and concentric/eccentric muscle contractions. Different response of the muscle fatigue between two different muscle contractions (isometric and concentric/eccentric contractions) was examined by comparison of parameters which were median frequency, median power and RMS value. Healthy 16 young persons without previous musculoskeletal diesease history were tested with Noraxon Myosystem 2000 EMG measurement system. In this study, two different exercises were performed. First exercise was concentric/eccentric exercise. Second exercise was isometric muscle contraction. In the case of the isometric exercise, median frequency was decreased, but median power and RMS were increased. However, during the concentric/eccentric exercse, median frequency was increased, but median power and RMS were decreased. Both of those revealed that the pattern of the median frequency was W type, but median power and RMS were M type as time passed. In this study, the patterns of the muscle fatigue during concentric/eccentric exercise as well as isometric exercise were identified. It will be helpful to prevent musculoskeletal injury from over-working andexercising.

Zonisamide was administered to 20 patients with refractory epileptic seizures. The mean duration of the administration was 6 months, and the mean dosage was 7.2 mg/kg/day. The efficacy of zonisamide was rated remarkable in 15% of the cases, improvement in 40%, and no change in 45%. The response rates of zonisamide were 62.5% for myoclonic seizures, 50% for tonic-clonic seizures, 80% for atonic seizures and 33.3% for atypical absence seizures. There was no correlation between the clinical response and dose or serum concentration of the drug. The adverse effects were observed in 35% of the cases which were drowsiness, dizziness, ataxia, nausea, and vomiting. In all cases, however, the administration of zonisamide could be continued.

It is well known that the medullary carcinoma of the breast is one of the special types of breast carcinoma with a good prognosis. At present, the medullary carcinoma of the breast is subclassified into 3 types: typical medullary, atypical medullary and nonmedullary carcinoma. Among them, the former has the best prognosis. We reviewed the film mammographic and ultrasonomammographic findings of 13 patients according to the reevaluated histopathologic diagnosis. Typical medullary carcinoma shows a well circumscribed mass with surrounding halo on film mammogram, and well defined mass with central intermediate echogenicity and peripheral low echogenicity and posterior acoustic enhancement on ultrasonomammogram. Atypical medullary carcinoma shows relatively well circumscribed mass with partial marginal obliteration on film mammogram, and irregular bordered mass with inhomogeneous echogenicity due to focal necrosis in the mass and associated findings of thick boundary, asymetrical lateral shadowing on ultrasonomammogram. Nonmedullary carcinoma shows lobulated mass with surrounding parenchymal distortion and skin thickening on film mammogram, and relatively well defined lobulating mass with surrounding parenchymal distortion and marked heterogeneous internal echogenicity on ultrasonomammogram. Therefore, differentiation between typical medullary carcinoma with good prognosis and atypical medulary or nonmedullary carcinoma with poor prognosis, may be possible by various diagnostic imaging modalities preoperatively. But further collective study shall be needed in near future.

Antiseptics are substances that kill or prevent the growth of microorganisms when applied to living tissue. They must be effective against microorganisms but must also retain their activity in presence of body fluids without being harmful locally or systemically. Among many antiseptics, Betadine(R) has been widely used because of its low toxicity and high germicidal efficacy. We reported 2 cases of allergic contact dermatitis to Betadine(R) in surgical patients. They had eczematous eruption along the Betadine(R) applying sites. Path tests Betadine(R) confirmed the diagnosis.

8.Pneumoperitoneum Associated with Pneumomediastinum, Pneumothorax, Subcutaneous Empysema during Intubation and Positive Ventilation.
Journal of the Korean Society of Emergency Medicine 2005;16(1):214-217
Pneumoperitoneum associated with a pneumothorax, pneumomediastinum, and subcutaneous emphysema during intubation and positive ventilation has rarely been reported. In general, such a pneumoperitoneum requires conservative treatment; therefore, it should be distinguished from pneumoperitoneum associated with a hollow viscus perforation. Our case involved a 47-year-old man treated with intubation and positive ventilation for the maintenance of airway patency. Not only a pneumothorax, pneumomediastinum and subcutaneous emphysema but also free intra-abdominal gas was observed on the chest X-ray. No evidence of a hollow viscus perforation was found on physical examination and the upper gastrointestinal series. The patient was treated conservatively for 10 days; then, the pneumoperitoneum, the pneumothorax, the pnenumomediastinum, and the subcutaneous emphysema disappeared. In this report, we reviewed the clinical significance and the anatomical relation of pneumoperitoneum associated with a pneumothorax, pneumomediastinum, and subcutaneous emphysema.

BACKGROUND: The Sampung Collapse took place at 17:55 June 29, 1995. The rescue operation encountered 458 dead and 477 multiply traumatized patients and 464 non traumatized peoples. We wanted to present basic data for disaster planning for example of Sampung Collapse. METHODS: We made a survey of accident field immediately after accident and interviewed with victims, victim's famaly, and rescuer. We analysed the medical record and SCL-9 (Hopkins symptom check list 90R) which was checked several list with victims, victim's family and control group. RESULT: The mean RTS was 11.9 and the mean ISS was 4.3.96 long bone fractures occurred in 76 patients. 127 case of vertebral injury occurred in 63 patients. Total number of surgical operations were 237. There are also many crushing injury and acute post-traumatic stress diseases. CONCLUSION: There are many injury types which are crushing injury, vertebral injury, blunt trauma and acute PTSD(post traumatic stress diseases). Thus, The field management, especially field triage, is very important. And, the urgent patients were 72 patients, about 5% of total patients, witch needed intensive care in tirtiary hospital. Therefore, we need to plan out the expeditious proper management. and prevention of disaster propagation.
