A case of chondroma of soft tissue of right hand in 23-year old man was reported. The presenting symptom was a slow growing mass, causing mild tenderness. Radiologic examination revealed a well demarked and lobulated calcified mass, was located extraskeletally. Specimen exised from soft tisssue of the hypothenar area of the hand was 5×4×3.5cm sized mass, had gelatinous and gray-whitish appearance. On microscopical examination, the tumor was classified as a chondroma of soft tissue.

Systolic time interval measurements were made sequentially during second, third trimesters and postpartum period. Recordings were made in the supine position after bed rest for at least five minutes in order to obtain a steady state. In second trimester, pre-ejection period index (PEPI) was significantly shortened and left ventricular ejection period index(LVETI) remained normal while PEP/LVET decreased. Four possible mechanisms may be involved to account for the alterations in hemodynamic changes during this period(late stage of second trimester) : (1) increased metabolic demands of pregnancy: (2) hemodynamic effects of hypervolemia: (3) circulatory adjustments secondary to an arteriovenous shunt-like effect of the placental circulation: (4) cardiovascular effect of steroid hormone. The third trimester was characterized-by a markedly shortened LVETI, a prolonged PEPI and PEP/LVET. This findings are consistent with impaired left ventricular performance and are probably due to decreased left ventricular preload resulting from diminished venous return secondary to inferior vena caval obstruction by the large gravid uterus. In the postpartum period, the PEPI and PEP/LVET remained elevated and the LVETI shortened in the supine position. It is concluded that alterations in systolic time intervals occur normally during the course of uncomplicated pregnancy and persist into the postpartum period.

STATEMENT OF PROBLEM: Temporary soft relining materials are used in a diverse clinical situations such as tissue conditioner, relining material, functional impression by varying its viscoelasticity. However, reproduction of consistent viscoelasticity has been not possible. MATERIALS AND METHODS: Considering setting mechanism of this material, this study has measured the effect of varying amount of void in dynamic viscoelasticity of soft relining material, with three different mixing methods. In each methods 10 specimens were made and subjected to dynamic viscoelastic test which were measured at specific times over period of 72 hours. RESULTS: The analysis of the result shown that there was no statistically significant differences between different mixing methods. CONCLUSION: Different mixing methods had no effect over control of viscoelasticity of soft lining material. Further research is recommended for under similar oral environmental condition.

The authors report two cases of high cervical spinal chordomas that were removed via the median labiomandibular glossotomy(MLG) approach. One patient was a 62-year-old female in whom an extradural chordoma was found at the level of C3 vertebra with huge prevertebral extension, and causing dyspnea and dysphagia; the other was a 47-year-old female, found to be suffering from a chordoma of C2 vertebral body, which was found incidentally. After removal of the tumors, ventral instrumented fusions were performed in both patients, who showed good recoveries with only minor complications. The MLG approach is radical, and rarely performed by neurosurgeons, but for treatment of an expanded high cervical lesion that needs ventral surgery and seems to be inaccessible via the conventional transoropharyngeal or anterolateral retropharyngeal route, it should be considered. The authors discuss the clinicopathological characteristics of spinal chordomas and general considerations of the MLG approach to high cervical lesions, and briefly describe the surgical techniques involved in this approach.

PURPOSE: To evaluate the classification of punctal stenosis based on the shape of the external punctum, clinical characteristics and histopathologic features. METHODS: Patients who experienced tearing and were diagnosed with punctal stenosis were evaluated in this study. Punctal stenosis was classified according to the shape of the lower external punctum, which included membranous type, slit type, horseshoe type, and pinpoint type. Tear meniscus height, 2% fluorescein dye disappearance test and lacrimal pathway irrigation were measured or performed. For treatment, a punctal snip operation and silicone tube placement were performed, and the peripunctal histopathological findings were evaluated. RESULTS: Punctal stenosis was classified into four types: membranous type (17 eyes, 21.5%), slit type (11 eyes, 13.9%), horseshoe type (25 eyes, 31.6%), and pinpoint type (26 eyes, 32.9%). The tear meniscus was significantly higher, and the 2% fluorescein dye disappeared significantly more slowly in the punctal stenosis group. However, correlation of the tear meniscus height and 2% fluorescein dye disappearance test with the punctum shape was not statistically significant. A history of previous chemotherapy was significantly associated with the occurrence of punctal stenosis, especially the membranous type (p < 0.05). Histopathologic evaluation of the punctum showed differences between the punctum types. Pinpoint puncta exhibited a high density of muscle fibers, while they were faintly visible in the membranous type. CONCLUSIONS: Acquired punctal stenosis has various shapes, and the major types of stenotic puncta exhibited unique histopathologic features. Punctal stenosis and its pathophysiology may be related to multiple factors, such as age and systemic 5-fluorouracil chemotherapy history.

We saw a case of minoxidil induced pericardial effusion in a 36 years old female who developed generalized edema, weakness and hypertrichosis after taking minoxidil for 1 year. Her chest PA showed globular shaped cardiac enlargement and pulmonary congestion. Echocardiography of the heart showed moderate amount of pericardial effusion. 10 days later after cessation of the drug administration and conservative managements, her chest PA showed marked improvement of heart size and pulmonary congestion. 20 days later her blood pressure became normal with the continued use of other antihypertensive drugs.

Nowadays in the field of plastic surgery, operations with no general anesthesia have been much increased, using daily surgery center. We used "Propofol TCI system" to control exact target concentration of conscious sedation and to reduce any systemic complication of the other local anesthetics. Twenty of ASA Class I or II patients were scheduled for elective surgery using Diprifusor(R) TCI system at 0.8-1.9 ug/ml target concentration. We estimated the proper target concentration, time of awakening, postoperative patient satisfaction and presence of postoperative amnesia. All the patients was satisfied except one patients who underwent nasal tip plasty. The target concentration of the conscious sedation varies with age and the type of operation but average concentration was 1.4-1.6 ug/ml. The average time of awakening, which we estimated by the time of eye opening was 2.6 minutes. Postoperative systemic complication and unusual vital sign were not present. We present here our satisfactory results using propofol infused by TCI(Target controlled infusion) system. This system is called 'Diprifusor(R)' and has a benefit of excellent sedative effect, low complication rate, safety, and rapid awakening time which enables the patient to return to his normal life cycle.

OBJECTIVES: The aim of this study was to determine the relationship between the core properties of professional socialization and social status satisfaction, economic reward satisfaction, and subjective class identification. METHODS: Medical knowledge and skill, autonomy, and professional value factors were used as essential properties of professional socialization to determine the association with job satisfaction and subjective class identification. The authors used a self-administered questionnaire survey and collected nationwide data between July and August 2003, with 211 responses used for final analysis. RESULTS: 'Age' and 'trust and respect' were positively associated with social status satisfaction, and 'occupation' was negatively associated. 'Income' and 'trust and respect' were positively related to economic reward satisfaction, and 'practicing for oneself', and 'a sense of duty and attendance' were negatively related. 'Practicing for oneself', 'not believing explanations', and 'a sense of duty and attendance' had a positive relationship with subjective class identification. 'Income', 'knowledge system', 'medical mistakes', 'treating like goods', 'meaning and joy', and 'trust and respect' had a negative relationship. CONCLSIONS: The core property variables of professional socialization had a different relationship with social status satisfaction, economic reward satisfaction and subjective class identification. In particular, many core property variables were associated with subjective class identification positively or negatively. The development of professional socialization would help promote job satisfaction and subjective class identification.

PURPOSE: Increased technologic capabilities have allowed for the expanded use of ultrasound beyond simple differentiation of a lesion as solid versus cystic nature, allowing us to classify lesions into various categories based on a number of descriptive features. The purpose of this study was to investigate whether to predict the preoperative prognosis of breast cancer through the correlation between ultrasonographic images and the grade of malignancy. MATERIALS AND METHODS: The patient population for this study consisted of 107 patients with infiltrative ductal carcinoma who were evaluated using ultrasound technology. Ultrasonographic findings were divided as follows: Type I, round or oval shape and regular border; Type II, partially round or oval shape and partially irregular border; and Type III, irregular shape and irregular border. RESULTS: 1. The frequency of grade 1 (G1) was significantly higher in the Type I group than the othergroups. 2. In the 2.0 cm sized mass, the lymph node metastasis rate was significantly lower in the Type I group than the other groups. 3. In all the groups, Estrogen receptor (ER) positivity was insignificant regardless of tumor size and type. 4. In the 2.0 cm sized mass, c-erbB-2 positivity was significantly lower in the Type I than the other groups. There was no clear difference among the three groups in tumors greater than 2.0 cm in size. CONCLUSION: These results show that our classification of ultrasonographic images reflect the grade of malignancy in terms of clinicopathological features in breast cancers less than 2.0 cm in size. Therefore, ultrasonographic findings may help predict the preoperative prognosis in T1 size breast cancer, although further study is required.

Approximately 100 drugs have been reported to affect the lungs adversely. Among these, pulmonary toxicity caused by antieneoplastic agent is being recognized more frequently. Cyclophosphamide is an immunosuppressive alkylating agent used for the treatment of a wide variety of malignant and nonmalignant diseases. The incidence of pulmonary toxicity is probably less than 1 percent The first case was reported in 1967. Since then, more than 20 well-documented cases of pulmonary toxicity associated with cyclophosphamide have been reported in the literature. In Korea, three patients were identified with cyclophosphamide-induced lung disease. The typical features of toxicity include dyspnea, fever, cough, new parenchymal infiltrates, gas exchangs abnormalities on pulmonary function tests, and pleural thickening on chest roentgenogram. The best approach to management is early diagnosis, discontinuation of the offending drug and administration of corticosteroid therapy. Recently, we experienced a case of diffuse alveolar damage induced by cyclophosphamide. The patient presented with early-onset pulmonary toxicity and died of repiratory failure despite early use of corticosteroid.
