IgA nephropathy is the most common form of glomerulonephritis characterized by deposit of IgA on mesangium. We experienced an elderly patient who was admitted for generalized edema, and diagnosed IgA nephropathy and early gastric cancer concomittantly. It has been reported that the incidence of nephrotic syndrome combined with malignancy increases with aging. Moreover, close relationship between IgA nephropathy and malignancy has been reported especially in the elderly patient. So, active investigations for possible malignancy are required in case of elderly patient with IgA nephropathy. In this case, we found improved proteinuria and hematuria of the patient after tumor resection during following up. This case suggest causal association between early gastric cancer and IgA nephropathy clinically.

In allogeneic transplantation, including the B6 anti-BALB.B settings, H60 and H4 are two representative dominant minor histocompatibility antigens that induce strong CD8 T-cell responses. With different distribution patterns, H60 expression is restricted to hematopoietic cells, whereas H4 is ubiquitously expressed. H60-specific CD8 T-cell response has been known to be dominant in most cases of B6 anti-BALB.B allo-responses, except in the case of skin transplantation. To understand the mechanism underlying the subdominance of H60 during allogeneic skin transplantation, we investigated the dynamics of the H60-specific CD8 T cells in B6 mice transplanted with allogeneic BALB.B tail skin. Unexpectedly, longitudinal bioluminescence imaging and flow cytometric analyses revealed that H60-specific CD8 T cells were not always subdominant to H4-specific cells but instead showed a brief dominance before the H4 response became predominant. H60-specific CD8 T cells could expand in the draining lymph node and migrate to the BALB.B allografts, indicating their active participation in the anti-BALB.B allo-response. Enhancing the frequencies of H60-reactive CD8 T cells prior to skin transplantation reversed the immune hierarchy between H60 and H4. Additionally, H60 became predominant when antigen presentation was limited to the direct pathway. However, when antigen presentation was restricted to the indirect pathway, the expansion of H60-specific CD8 T cells was limited, whereas H4-specific CD8 T cells expanded significantly, suggesting that the temporary immunodominance and eventual subdominance of H60 could be due to their reliance on the direct antigen presentation pathway. These results enhance our understanding of the immunodominance phenomenon following allogeneic tissue transplantation.

Aspergilloma and Allergic Bronchopulmonary Aspergillosis(ABPA) are different types of the pulmonary aspergillosis spectrum of diseases. ABPA is an inflammatory disease that causes hypersensitivity to Aspergillus spores growing in the bronchi, which is characterized by asthma, recurrent pulmonary infiltrations or mucoid impaction, eosinophilia and central bronchiectasis. Aspergilloma is a simple colonization of fungus within a cavitary lung lesion, but these diseases rarely coexist. A case of ABPA, coexistent with Aspergilloma, was experienced in a 31 year-old female. The diagnosis was confirmed by the immediate cutaneous reactivity to Aspergillus fumigatus, elevated total IgE antibodies, peripheral eosinophilia, bronchiectasis, growth of Aspergillus species in a sputum culture and radiographic infiltration. Treatment, with prednisone and itraconazole, led to improvement of the respiratory symptoms, reduction of the cavitary lesion and in the total serum IgE level.

BACKGROUNDS: As Korea has advanced into the aging society, Acute Coronary Syndrome is increased in number, especially elderly age group. The symptoms of acutecoronary syndrome in eldery were presented in atypical feature frequently. We studied the relation of the first symptom and diagnosis of acutecoronary syndrome and distribution of risk factor and coronary angiographic finding in elderly patient of korea society. METHODS: The subjects who were under went coronary angiography between 2002.5 and 2003.8 were dividedunder 65 years old group and over 65 years old group. And each group described diagnosis, risk factor, first symptom and coronary angiographic finding retrospectively. RESULTS: The diagnosis of unstable angina are more higher(46.5% vs. 26.1%, p<0.01) in the over 65 years old group and the first significant symptom of typical chest pain was more higher(57.4% vs. 47.6%, p<0.01) in the under 65 years old group and dyspnea was more higher(22.8% vs. 9.2%, p<0.01) in the over 65 years old group. The number of abnormal vessel were more higher(66.3% vs. 46.9%, p<0.01) in the over 65 years old group. CONCLUSION: Over 65 years old group compared with younger age group were prewented more frequently angina equivalent symptom than typical chest pain. And at the diagnosis of Acute Coronary Syndrome, over 65 years old group showed more severe coronary angiographic finding. Consequently, early stage of diagnostic approach and treatment need scrupulous attention in the elderly patients.

BACKGROUND: Metabolic syndrome, a concurrence of disturbed glucose and insulin metabolism, over- weight and abdominal fat distribution, dyslipidemia and hypertension, is associated with subsequent de- velopment of type 2 diabetes mellitus and cardiovascular disease, especially coronary heart disease. The aim of the study is to assess the relationship between metabolic syndrome and coronary heart disease in elderly greater than 65 years old. METHODS: Eighty two elderly patients greater than 65 years old who underwent coronary angiography were divided into two groups with metabolic syndrome or without metabolic syndrome, and assessed the association with coronary angiographic finding. The metabolic syndrome factors and cardiovascular risk factors of JNC 7 were investigated to assess the relationship with coronary heart disease in elderly. Coronary heart disease was defined as 50% or greater diameter in stenosis of coronary artery in coronary angiography. RESULTS: In elderly patients with metabolic syndrome, coronary angiographically abnormal findings(p<0.05) and multi vessel disease findings(p<0.05) were presented significantly higher than non metabolic syndrome patients. In elderly patients with 3 and more cardiovascular risk factors of JNC 7, coronary angiographically abnormal findings(p<0.05) and multi vessel disease findings(p=0.059) were presented more than the other patients. Diabetes mellitus was related significantly with coronary heart disease(p value 0.044). CONCLUSION: In elderly patients, metabolic syndrome was significantly related with coronary heart disease and diabetes mellitus had strong relationship with coronary heart disease. Metabolic syndrome and cardiovascular risk factors of JNC 7 should be further evaluated to assess the relationship with coronary heart disease in the future.

Takayasu's arteritis is generally recognized as a chronic, idiopathic, inflammatory disease, which affects the aorta and the proximal portions of its major branches. We experienced a patient with Takayasu's arteritis who was presented with main pulmonary artery stenosis and right coronary ostial occlusion without involvement of aorta nor its major branches. She was managed with pulmonary arterioplasty and coronary artery bypass graft. This case emphasize that the disease cannot affect the aorta.

A 51-year old woman was admitted to our hospital because of Exertional dyspnea, Palpitation, Headache, upper-limb hypertension, and lower-limb claudication. A loud systolic bruit was audible along Lt. carotid artery. Upper limb hypertension was responsed to drug moderately (included ACEI, alpha, beta-blocker, Ca++-channel blocker), but claudication of lower limb was aggravated, also on exertion, Blood Pressure of upper-limb was elevated to 180 mmHg. So, chest CT and Aortogram was performed, we confirmed long segmental stenosis from thorasic Aorta to the renal a. bifurcation level. Finally, We performed after axillo-femoral bypass surgery. After surgery, upper limb hypertension and lower limb claudication was improved.

A 33-year old male was admitted due to continuous high spiking fever for 2 months via local clinic. He had been diagnosed pulmonary tuberculosis at local clinic. However, spiking fever had not been controlled by anti-tuberculous medications. Chest PA showed confluent consolidation on right upper & mid-lung field. 5 anti-tuberculous regimens (Streptomycin, Isoniazid, Rifampin, Ethambutol, Pyrazinamaide) were administered initially and steroid therapy was followed for relieving toxic symptoms Very slowly resolved chest X-ray lesion and continuous fever suggested the possibility of misdiagnosis. After 60th hospital day, the chest X-ray lesion was resolved gradually and fever subsided almost completely. He was discharged on 76th hospital day with anti-tuberculous drugs and steroid(prednisolon), without any other problems except sustained mild fever.

In children and adolescents, dental age estimation is performed with the development of the teeth. Various statistical analysis methods have been used to determine the relationship between age and dental maturity and develop an accurate method of age calculation. This study attempted to apply a neural network model for the statistical analysis of dental age estimation in children and evaluated its applicability. This study used 1196 panoramic radiographs of patients aged 3–16 years, and 996 and 200 were randomly classified into training and test sets, respectively. The dental maturity of the mandibular left teeth was evaluated using Demirjian's method, the neural network model using the backpropagation algorithm was derived using training sets, and the errors were evaluated using 100 radiographs of each male and female as test sets. In addition, multiple linear regression analysis was conducted on the same training set, and the error was calculated by applying it to the test set and comparing it with the error of the neural network model. In the neural network model, the mean absolute error (MAE) and root mean squared error (RMSE) were 0.589 and 0.783 in male subjects and 0.529 and 0.760 in female subjects, respectively. In the multiple linear regression model, the MAE and RMSE were 0.600 and 0.748 in male subjects and 0.566 and 0.789 in female subjects, respectively. When applying the neural network model to the statistical analysis of the dental developmental stage, the results were as accurate as those of conventional statistical analysis methods. This study’s approach is expected to be useful for estimating the ages of children.

BACKGROUND: We consider that heart failure in elderly and Chronic renal failure patients is closely related to LV diastolic dysfunction. To determine the association between LV diastolic functions and heart failure, we assessed LV diastolic functions in elderly patients with pulmonary congestion and in Chronic renal failure patients by using pulsed doppler echocardiography. METHODS: In order to assess LV diastolic function, we performed pulsed doppler echocardiography on elderly patients with pulmonary congestion and Chronic Renal Failure patients from Nov; 2000 to June; 2001. The following parameters were used as indices of LV diastolic function; Mitral E wave(E), Mitral A wave(A), F/A ratio, Deceleration time(DT), Isovolumic relaxation time(IVRT), Systolic pulmonary venous flow(PVs), Diastolic pulmonary venous flow(PVd), PVs/PVd ratio. RESULTS: In elderly patients groups with pulmonary congestion, there was significant decreased in E/A ratio compared with CRF patients(0.693+/-0.18 vs 0.905+/-0.116, p<0.01). There was significant increase in deceleration time and isovolumic relaxation time in elderly patients with pulmonary congestion compared with CRF patients(DT 255.83+/-54.41 vs 210.80+/-48.53 p<0.05, IVRT; 123.06+/-26.07 vs 98.75+/-15.12, p<0.01). Although there was no significant difference, increased PVs/PVd ratio was noted in both groups. CONCLUSIONS: The results shows that the impairments of LV diastolic function were noted in both groups. Especially F/A ratio was significant decreased elderly patient group with pulmonary congestion and DT, IVRT were significant increase in elderly patient group with pulmonary congestion. Therefore Left ventricular relaxation is progressively impaired in old age and impaired LV relaxation results in in LV diastolic dysfunction But LV hypertrophy in ESRD patients results in LV diastolic dysfunction.
