BACKGROUND: This study intends to clear that the current cost reimbursement system of Korean medical insurance of health care. METHODS: By using insured medical record of Federation of Korean Medical Insurance Societies used in the demand tendency research of the type of services from feburary 1st to 28th of the year 1990, authors analyze the characterist,ic of components of charges per case in the type of health care facilities. RESULTS: The charge per case in the out-patient care of primary health care facility is 13,498 won, which is 54.6% by comparison with the secondary health care facility and 30.7 % by comparison wit,h the tertiary health care facility. Among these charges the amount of the cost for medical examinations and oral drugs are 73.9% in the primary health care facility and 71.8% in the secondary and 67.5% in the tertiary. Consequently, the services in the primary care are chiefly composed with the medical examinations and oral drugs. In addition to this point the author also finds that the charge per case is 3.5 times, the cost for oral drugs is 5.6 times larger than those of primary care, and therefore tertiary health care facility conduct various diagnostic examinations and prescript more expensive. CONCLUSIONS: There is a difference of basic medical cost ratio between primary, secondary and tertiary health care facility. These points can be lead to the presumption that the diseases under the structure of current medical insurance are overlapped irrespective of the charact.erisitcs of the type of health care facilites, and this is profitable to the tertiary health care facilities which can conduct various types of services. In conclusion, the frame a policy is needed to encourage primary care which are nothing but simple structure of charges.

PURPOSE: To evaluate MRI findings of malignant ovarian tumors. MATERIALS AND METHODS: MRI findings were retrospectively reviewed in 25 patients with surgically confirmed 30 malignant ovarian tumors(common epithelial tumor;23, sex cord stromal tumor;2, endodermal sinus tumor ; 1, metastatic tumor ;4). The findings evaluated were the lesion size, solid and/or cystic component, wall thickness, septal thickness, necrosis, invasion of adjacent organ, ascites, and adenopathy. RESULTS: MRI findings of the malignant ovarian tumors were as follow:Size of lesion was 5-35cm(mean 14cm) ;solid component was present in 80%(24/30);wall thickness was more than 3ram in 90%(27/30);septal thickness was more than 3ram in 70%(21/30);tumor necrosis was present in 40%(12/30%) ;invasion of adjacent organ was present in 76%(19/25);ascites was present in 56%(14/25);lymphadenopathy was present in 24% (6/25). MRI findings of absence of solid component(6/6), even wall and septal thickness(7/7, 19/19) were found only in epithelial tumors. Uneven septal thickness more than 3mm(7/11) was a predominant MRI findings of non-epithelial tumors. Well-defined cystic lesion within solid component was seen in Krukenberg tumors. CONCLUSION: Evaluation of the lesion size, internal architecture, invasion of adjacent organ, ascites, and lymphadenopathy in MRI would enable diagnosis of malignant ovarian tumors and could lead to possible differential diagnosis of epithelial tumors from non-epithelial tumors.

We report a case of myelodysplastic syndrome (MDS) with unique histopathological findings in which numerous infiltrated neutrophils exhibited nuclear segmentation anomalies. In comparison with well-described neutrophilic dermatoses of myelodysplastic syndrome such as Sweets syndrome and pyoderma gangrenosum, this case took a rapid and aggressive clinical course. We suggest that a nuclear segmentation anomaly, pseudo Pelger-Hiiet anomaly, is likely to reflect acute transformation of MDS and can be a poor prognostic marker.

BACKGROUND: The cornified cell envelope (CE) is a unique structure found in the terminal differentiation of the skin. The precursor proteins of the CE are composed of many candidate structural proteins, among which invalucrin and filaggrin are important ones to participate in the complicated process of forming, the complex structure. OBJECTIVE: The purpose of this study was to evaluate the usefulness of expression of involucrin and filaggrin as markers of terminal differentiation in various skin disorders including tumors. METHODS: Immunohistochemical studies were performed in the formalin-fixed, paraffin-embedded skin samples of non-tumors (41 cases) and tumors (43 cases).

We report two cases of cellulitis on the saphenous venectomy scar which developed after a coronary artery bypass graft(CABG). A 68-year-old male and a 62-year-old female developed acute cellulitis in the saphenous vein donor extremity after CABG. The repeated bacterial cultures were negative in both cases. However, onychomycosis was confirmed in one patient. The intervals between CABG and the initial bout of cellulitis in the male and female patient were 10 and 22 months, respectively. Although the exact pathogenesis remains obscure, factors such as direct bacterial infection, hypersensitivity to streptococcal exotoxins, a local compromise of lymphatic and venous drainage, and fungal infection might have contributed to the development of cellulitis in these patients.

The authors carried out various treatment modalities in 74 consecutive patients with hypertensive basal ganglionic-thalamic intracerebral hemorrhage and were admitted to the Department of Neurosurgery. Konkuk University Hospital, from Jan. 1991 to Dec. 1993. A variety of prognostic factors that influence mortality were observed. The locaton of hematoma was at the basal ganglia in 47 cases and at the thalamus in 27 cases. The prognosis gets poorer as the hematoma extended wider and deeper. The prognosis was unfavorable when the hematoma was over 30cc(P<0.001). The mortality rate was higher in cases with IVH than in cases without IVH(P<0.005). In cases with IVH, 19 cases(26%) showed dilated 4th ventricular hemorrage and higher mortality rate(P<0.001). Cases in which the GCS were less than 9 on admission showed higher mortality rate(P<0.0001). The mortality rate was also higher if the midline shift was more than 10mm on the initial brain CT scan(P<0.005). THe group where the unilateral or bilateral pupillary light reflex was unreactive(35cases) showed poorer prognosis than the group where the bilateral pupillary light reflex was reactive(P<0.0001). The ventriculocranial ratio(VCR), hydrocephalus, surrounding edema edema around the heamtoam, and treatment modality were not related to the prognosis. The significant prognostic factors in patients with hypertensive basal ganglionic-thalamic intracerebral hemorrhage were location and type of hematoma, whether or not the volume of hematoma is more than 30cc, IVH, dilated 4th ventricular hemorrhage, Graeb's score of more than 7, GCS of less than 9, midline shift of more than 10mm, and reactivity of pupillary light reflex.

The transesophageal echocardiography (TEE) has been used for the assessment of right and left ventricular function, valvular structure and function, regional wall motion abnormalities and localization of intravascular catheters, cannular and prosthesis. We inserted the pulmonary artery catheter (PAC) under the guidance of intraoperative TEE because of the difficulty of placing PAC with the pressure tracing method in two patients. The PAC was inserted from right atrium to right ventricle with the basal four chamber view and advanced to pulmonary artery through pulmonary valve with the longitudinal view of TEE. We observed typical pulmonary arterial wave form to confirm the correct position. We suggest that the TEE can be used for successful placement of a PAC to facilitate manipulation of the catheter as an alternative method in the patients whose PAC can not be positioned with the pressure tracing method.
