The dysplastic hip presents problems to the orthopedic surgeon in the reconstruction of hip using total hip prosthesis. The use of bone grafts to reconstruct the lateral acetabular bone deficiency is very popular. We investigated in 23 patients(5 cemented cup and 18 cementless cup). Sixteen patients were women and seven were men, whose average age was 42.4 years old; their average followup was 4.6 years. The average Harris hip score improved from a preoperative value of 48 points to a postoperative value of 87 points. Five cases showed radiographic loosening, in which 3 cases loosening from five cemented cup and 2 cases from cementless cup arthroplasty. Radiolucent lines were observed more frequently with cemented cups at last follow-up. Of the 23 cases, 18(78%) was successful. Postoperatively limping was a major problem because most patients in this series had unilateal disease. The grafted bone was incoporated by an average time of 7.4 months, and minor resorption was showed at last follow-up. In our series, cementless cups with autogenous bone graft noted good results than cemented cup arthroplasty.

BACKGROUND: In patients with endometrial carcinoma, preoperative evaluation of exact staging has important prognostic and therapeutic implications. The incidence of pelvic and aortic lymph node involvement in endometrial carcinoma depends on grade of tumor differentiation and depth of myometrial invasion. MATERIAL AND METHOD: To evaluate whether MRI provides a preoperative assessment for staging of endometrial carcinoma, MRI was undertaken in 28 patients, a few weeks before operation. Myometrial invasion was devided in three categories, and involvement of cervix, adnexa, and pelvic cavity were classified. RESULTS: The results of MR imaging were compared with these of pathology. The preoperative MRI staging of endometrial carcinoma was correct in 22 out of 28 patients. In the evaluation of myometrial invasion, the MR imaging underestimated in 4 cases and overestimated in 1 case. CONCLUSION: In patients with endometrial carcinoma, MR imaging is very useful in the assessment of the depth of myometrial invasion, stromal invasion of cevix, lymphatic & pelvic metastases and extent of the lesion.

Forty cases of infiltrating duct carcinoma of the breast were examined immunohistochemically for expression of TGF-beta and angiogenesis in order to analyze significant correlation with prognostic parameters including tumor size, axillary lymph node metastasis, clinical stage, histologic grade, estrogen receptor and progesterone receptor status. The TGF-beta expression was observed in tumors center and advancing edges of tumors. To determine microvessel density for angiogenesis, we stained endothelial cells for Factor VIII related antigen and counted microvessel within tumor. The results were as follows: 1) The strong immunohistochemical expression of TGF-beta and higher counts of microvessels were observed in advancing edges of tumors (p<0.05). 2) The TGF-beta expression in the advancing edges of tumors was closely related to clinical stage and presence of axillary lymph node metastasis (p<0.05). 3) The mean microvessel counts were significantly higher in tumors from patients with axillary lymph node metastasis and increased with increasing clinical stage (p<0.05). 4) The TGF-beta expression was not related to histologic grade, estrogen receptor and progesterone receptor status(p>0.05). Therefore, the results suggested that the TGF-beta expression and angiogenesis in infiltrating duct carcinoma of the breast may play an important part in prognostic factors, closely related to the lymph node metastasis and clinical stage.

Even a single brain infarct can cause dementia when it occurs in functionally critical areas of the brain. A 71- year-old female developed sudden cognitive impairment without any other focal neurologic deficits. A brain MRI revealed a bilateral anterior fornix infarction. Neuropsychological evaluation revealed verbal and visual memory deficits, visuospatial dysfunction, and frontal executive dysfunction. The cognitive impairment did not improve for 3 months and the patient showed impairments in daily activities. We report a patient who demonstrated strategic infarct dementia after a bilateral anterior fornix infarction.

PURPOSE: To evaluate the correlation between diabetic retinopathy (DR) and arteriolosclerosis in patients with NIDDM (non-insulin-dependent diabetes mellitus), to investigate the risk factors of DR, and to assess the change of the correlation according to the risk factors. METHODS: The study subjects were selected from consecutive routine clinical visits by random sampling from July 2002 to June 2003. The patients were divided into two groups according to the presence of DR, and the patients' charts, fundus examination and blood test were retrospectively reviewed. ETDRS (Early Treatment DR Study) classification for DR and Scheie classification for arteriolosclerosis were used. Statistical analysis was conducted with SPSS program (version 10.0). The confidence interval was set to 95%, and the level of significance was set at p=0.05. RESULTS: DR had a statistically significant correlation with arteriolosclerosis, especially according to duration of diabetes mellitus (p<0.05). Risk factors including diabetes mellitus duration, HgA1c level, and LDL (low-density lipoprotein) cholesterol level showed statistically significant difference (p<0.05). CONCLUSIONS: From the result of analysis, DR has a statistically significant correlation with arteriolosclerosis, especially according to the duration of diabetes mellitus. To prevent vision-threatening complications of DR, the degree of arteriolosclerosis as well as risk factors such as diabetes mellitus duration, serum HgA1c level, and LDL (low-density lipoprotein) cholesterol level should be carefully considered and monitored in the evaluation, progression, and treatment of DR.

This study was carried out to reveal the epidemiologic characteristics of psoriasis in Korea. Seventeen university hospitals were engaged in this study, and the results were as follows : 1. The number of psoriasis patients during the 10 years from January 1977 to March 1987 was 1.05% of all the outpatients; the male to female-ratio was 1.08:1. 2. In the prospective study, the number of psoriasis patients was 2.3% of all the outpatients in 1987, 2.8% of all the outpatients in 1988 and the male to female ratio was 1.26:1. 3. The most prevalent age of onset was 20-29 years ; 81.1% were living in urban areas; and a family history was obtainable in 19.8% with parents holding the highest rank of 7.8%. 4. The most frequent duration of disease activity was under 5 years in 63.3%; the most common age for the worst condition was 20-29 yrs. The most common area size of skin involvement at the peak of the worst condition was less than 10%. 5. The most common initiating skin lesion began on the scalp in 20.2%, on the nail in 17.2%, pruritus in 63.0% with joint symptoms in 10.8%, and Koebner phenomena in 50.6%. 6. Emotional stress was the most common aggravating factor in 34.4%. The method of treatment that attained the best result was the combination therapy of oral medication and a topical agent. The best treatment modality was said to be the application of ointment with p.o.medication by as many as 28.4% of patients who took the leading rank. Photo-chemotherapy, effective with few complications, was not used much as it was not well-known in Korea until after 1980. Most people had an accurate knowledge of psoriasis.

PURPOSE: To compare the differential radiologic findings of renal cell carcinoma presenting as a homogeneous solid mass (HS-RCC) and muscle-predominant angiomyolipoma (MP-AML). MATERIALS AND METHODS: Nine of 76 surgically and pathologically proven RCCs presenting at CT or magnetic resonance (MR) imaging as a homogeneous solid mass, and four cases of MP-AML were included in this study. Echogenicity at sonography, attenuation at non-enhanced CT (NECT), the contour of the mass, signal intensities at T1- and T2-weighted MR imaging, the existence of a capsule, and the pattern and degree of enhancement at CT and MR imaging were retrospectively analyzed. RESULTS: Two of five HS-RCCs were isoechoic and three were hyperechoic. Two of three MP-AMLs, however, were isoechoic, and one was mixed echoic. All nine HS-RCCs were round or oval in shape, but three MPAMLs were lobulated and one was round. At NECT, seven of eight HS-RCCs were isodense and one was hypodense compared to surrounding normal renal parenchyme, but three MP-AMLs were hyperdense masses and one was isodense. At enhanced CT, HS-RCCs showed various degrees of homogeneous enhancement, but all MP-AMLs showed moderate homogeneous enhancement. All three MP-AMLs demonstrated heterogeneous hypointensity at T2-weighted MRI and homogeneous hypointensity at T1-weighted MRI. HS-RCCs showed various signal intensities at both T1- and T2-weighted MRI, and in five cases, heterogeneous high signal intensity at T2-weighted MRI. Capsules were observed in seven of nine HS-RCCs but not in any of the three MP-AMLs. At enhanced T1-weighted MRI, MP-AMLs showed mild to moderate enhancement, but HSRCCs showed mild, moderate, and strong enhancement in two, two, and five cases, respectively. CONCLUSION: Echogenicity, density at NECT, signal intensity at MR T2-WI, the contour of the mass, and the existence of a capsule are features which are useful in the differential diagnosis of HS-RCC and MP-AML.

OBJECTIVES AND METHODS: To directly examine the function of the endothelial cell(EC) and smooth muscle cell in umbilical arteries acquired from preeclampsia patients between June 1998 to November 1999, using a conventional tension measurement and bioassay experiment. RESULTS: Relaxation responses to EC-dependent relaxing agents including bradykinin and A23187 in human umbilical artery rings were significantly decreased in preeclampsia(p<0.01). Relaxation responses to EC-independent agents(SNP and SNAP) were also inhibited in umbilical artery rings acquired from preeclampsia patients(p<0.01). To test the change of endothelial cell function in preeclampsia without involvement of smooth muscle dysfunction, we used human umbilical artery and rabbit femoral artery as a donor and detector, respectively, in bioassay experiment. Relaxation responses to EC-dependent agents(A23187 and bradykinin) showed similar results to conventional tension measurement (p<0.01). Relaxation responses to 8-bromo-cGMP in human umbilical artery rings were also significantly decreased in preeclampsia(p<0.01). CONCLUSIONS: It can be concluded that increased vascular resistance in preeclampsia is not only due to the disturbance of endothelial function, but also to smooth muscle dysfunction.
