A 62-year-old male was admitted for evaluation of a mass shadow on chest film. Chest PA showed 7×5cm lobulated homogenous mass in right upper medial area of lung. On chest computed tomography, there was a Barge irregularly lobulated mass with central necrotic low density area in apical segment of right upper lobe. Right upper lobectomy of the lung was performed. Partial adhesion to parietal pleura of posterior mediastinum and severe adhesion to right upper apicoposterior segment was found during the operation Microscopic and ultrastructural studies(including immunocytochemical stains) of the mass revealed malignant fibrous histiocytoma.

Adrenal myelolipomas are rare, benign tumors cornposed of mature fat and bone marrow elements. Most are small, asymptomatic tumors found incidentally at postmortem examination, Fine needle aspiration biopsy can be used to confirm the diagnosis and avoid an unnecessary operation. We report a case of adrenal myelolipoma confirmed by fine needle aspiration biopsy. A 77-year-old woman with complaining of upper abdominal pain for 2 days was found to have an adrenal mass. She took dexamethasone frequently for 3 years due to multiple arthralgia. Ultrasono-graphy showed a 6cm-sized, suprarenal mass and a stone in the gall bladder with thickened wall. Computed tomography and magnetic resonance imaging scan also presented a suprarenal mass. Endocrinologic results were within normal limits. Adrenal myelolipoma was confirmed by computed tomography-guided fine needle aspiration biopsy without surgery.

A 62-year-old female was adrnitted to the Catholic University Hospital of Taegu-Hyosung with an intracerebral hemorrhage. She was operated on successfully, but developed bacterial pneumonia. She was then treated with sulperazone, tobramycin, and metronidazole for 1 month. After the antibiotic treatment, she suffered from a fever and bloody, mucoid diarrhea for 3 days, and was examined with a sigmoidoscope. The sigmoidoscopic examination revealed yellow patches of ulcerations and swelling covered with thick sero- sanguinous exudate in the distal transverse colon and sigmoid colon. A latex agglutination test for C. was performed on her stool, whereby difficile cytotoxin was negative, however, metronidazole resistant C. perfringens was isolated from anaerobic culture of the biopsied colon tissue. She recovered with 15 days using oral vancomycin treatment. The possibility of C. perfringens as a causative organism of pseuclomernbraneous colitis was discussed.

This study investigated the boundary of anserine bursa with the recommended injection site and shape on the insertion area of pes anserinus (PA), with the aim of improving clinical practice. Eighty six legs from 45 Korean cadavers were investigated. The mixed gelatin solution was injected to identify the shape of anserine bursa, and then the insertion site of the PA tendons was exposed completely and carefully dissected to identify the shape of the PA. The sartorius was inserted into the superficial layer and gracilis, and the semitendinosus was inserted into the deep layer on the medial surface of the tibia. The number of the semitendinosus tendons at the insertion site varied: 1 in 66% of specimens, 2 in 31%, and 3 in 3%. The gracilis and semitendinosus tendons were connected to the deep fascia of leg. Overall, the shape of the anserine bursa was irregularly circular. Most of the anserine bursa specimens reached the proximal line of the tibia, and some of the specimens reached above the proximal line of the tibia. In the medial view of the tibia, the anserine bursa was located posteriorly and superiorly from the tibia's midline, and it followed the lines of the sartorius muscle. The injection site for anserine bursa should be carried out at 20degrees from the vertical line medially and inferiorly, 15 or 20 mm deeply, and at the point of about 20 mm medial and 12 mm superior from inferomedial point of tibial tuberosity.

BACKGROUND: Mild iron deficiency anemia is known to be asymptomatic in most of the cases. In view of this, we studied response of the mild anemics to the maximal exercise loading test to learn whether or not they respond similarly to the normals. METHODS: The maximal exercise loading tests by Bruce's protocol were carried out in 22 female asymptomatic anemics with hemoglobin level of between 10.0gm/dL and less than 12.0gm/dL, and the results were compared with those of 44 non-anemic matched controls with mean hemoglobin level of 13.1gm/dL. The ages in both groups were in their 30's to 40's, and even the anemics were otherwise normal clinically and on various laboratory tests. RESULTS: There were no significant difference between two groups in VO2 max, HR max, VCO2 max and VE max and their derivatives including VT/VC and VE/MVV. CONCLUSIONS: Our results indicate that in patients with mild iron deficiency anemia, the cardiorespiratory response to maximal exercise loading is not different from the normals, and suggest that oxygen transport to tissues is not affected even at maximal exercise. probably by adaptive compensatory mechanism.

BACKGROUND AND OBJECTIVES: The plasma concentration of N-terminal pro-brain natriuretic peptide (NT-pro-BNP) is a st-rong prognostic indicator for patients with heart failure (HF) across all stages of the condition. Several clinical trials have de-monstrated convincingly that neurohormonal modulation on the renin angiotensin system (RAS) decreases plasma NT-pro-BNP level and results in favorable outcomes. But there are still limited comparative data on the neuro-hormonal modulatory effects of two RAS inhibitors: angiotensin converting enzyme inhibitor and angiotensin receptor blocker. SUBJECTS AND METHODS: This study was a prospective, multi-center, randomized, open-label, controlled, and non-inferiority study involving 445 patients with left ventricular ejection fraction (LVEF) less than 45%. Patients were assigned to receive either valsartan (target dose of 160 mg bid) or enalapril (target dose of 10 mg bid) for 12 months. We compared plasma NT-pro-BNP, high sensitive C-reactive protein (hs-CRP) level and echocardiographic parameters before and after treatment with valsartan or enalapril. RESULTS: The NT-pro-BNP and hs-CRP levels were significantly decreased after 12 months of treatment with valsartan and enalapril. The percentage change was similar between both groups. LVEF improved and left ventricular internal dimensions were decreased in both groups, and there were no significant differences between two groups. CONCLUSION: Valsartan is as effective on improving plasma NT-pro-BNP level as enalapril in patients with stable chronic HF.

OBJECTIVE: To determine the correlation between total anti-oxidant capacity (TAOC)and lipid peroxidase (LPO)levels in serum and disease activity in systemic lupus erythematosus (SLE). METHODS: The study population consisted of 99 patients with SLE according to the 1982 revised ACR criteria and 83 healthy controls.The serum TAOC levels in 99 patients with SLE and 83 healthy controls by the ABTS(R) inhibition method (Randox Ltd,Antrim,UK)and serum malondialdehyde (MDA)levels in 37 out of 99 patients with SLE were measured.Anti-dsDNA antibody (anti-dsDNA),albumin,AST,ALT,cholesterol,uric acid and creatinine were mea-sured to determine the association with the serum TAOC levels.The correlation between the serum TAOC levels and nephritis in 27 cases with nephritis out of 99 SLE patients was also investigated.The SLE disease activity was determined by the SLE disease activity index (SLEDAI)at the time of sample collection. RESULTS: Compared to the controls (1.37 +/- 0.127mmol/L),serum TAOC levels were significantly decreased (1.29 +/- 0.124mmol/L)in SLE patients (p=0.001). And there was a negative correlation between serum TAOC levels and SLEDAI total scores in the SLE patients (r=-0.388,p=0.0001),but no significant correlation between TAOC levels and C3 and anti-dsDNA.Further,a significant difference (p<0.04)in TAOC levels was found in SLE patients with and without nephritis.In comparison with other parameters such as AST,ALT,and cholesterol which might change anti-oxidant level,there was no correlation between the serum TAOC levels and them,except for serum uric acid (r=0.387, p=0.0001),creatinine,and albumin (r=0.507,p=0.0001).Additionally,we couldn't find significant correlation between the serum TAOC levels and MDA. CONCLUSIONS: The serum TAOC levels correlate significantly with SLE disease activity and are associated with nephritis.Also,this study showed a significant correlation with serum albumin levels in these patients.Conclusively,the measurement of the serum TAOC levels in patients with SLE will provide useful information on SLE disease activity.
