PURPOSE: We evaluated the usefulness of quantitative spiral CT to predict postoperative lung function in patients undergoing pulmonary resection. MATERIALS AND METHODS: Fourteen patients in whom pneumonectomy or segmentectomy were performed underwent preoperative chest spiral CT and pulmonary function test(PFT). Six patients underwent postoperative follow-up PFT. Ten patients underwent preoperative radioisotope(RI) lung perfusion scan. Preoperative CT data were postprocessed with contiguous pixel method ranged from -9107HU to -500HU to quantify total functional lung volume(TFLV) and regional volume to be resected(RFLV). Postoperative lung function was predicted by following formula;Predicted postoperative PFT value=preoperative PFT x 1-RFLV/TFLV). CT predicted value was compared with postoperative measured PFT value and those value of RI perfusion scan. RESULTS: CT predicted values were very close to postoperative measured value and RI predicted value, and were correlated well with postoperative measured values (FVC: r=0.988, P<0.001 ;FEV1: r=0.994, P<0.001) and RI predicted values (FVC :r=0.976, P<0.001 ;FEVl: r=0.974, p<0.001). CONCLUSION: Quantitative spiral CT was useful to predict postoperative lung function and could be an effective alternative to RI perfusion scan.

Crohn's disease is a rare inflammatory bowel disease in Korea which requires a differential diagnosis with intestinal tuberculosis. In the early stages of Crohn's diseaae, the combiation of bowel wall edema and spasm produces intermittent obstructive manifestations, so the usual subjective symptoms were appeared long standing diarrhea, low grade fever and abdominal pain and distension. We recently experienced a case of Crohn's colitis with repeated bowel obstruction in female adult who underwent surgical resection.

Solar urticaria is a fairly uncommon but Well recognized clinical entity characterized by erythema and wheal with itching immediately following exposure to sunlight or artifical radiation. A 33-year-old female had a six-year duration of urticaria, tightness of chest and dizziness that appeared within 15 minutes of exposure to sunlight. The action spectrum of this patient was between 320 and 400nm and the passive and reverse passive transfer test were negative. Solar urticaria of our patient appeared to belong to type g in the classification of Harber et al(1963). The patient was treated with antihistamines and repeated exposure to sunlight for inducing tolerance. After 3 months of the treatment, the symptoms did not appear even after 3 hours of exposure to sunlight.

Two-dimensional Doppler echocardiographic velocity profiles of four cardiac valves in a group of 85 infants and children with left to right shunt lesions(VSD, ASD and PDA) are presented. Velocities were obtained before operation and 10 days afterward. The results were as follows ; 1) VSD(type 2) Peak velocities of mitral valve were significantly decreased when compared preop. with postop. echocardiogram(n=37, preop 132+/-24, postop 98+/-16 cm/sec, p<0.0005). Peak velocities of tricuspid valve were also significantly decreased(n=30, perop 60+/-21, postop 50+/-17cm/sec, p<0.01). Peak velocities of aortic valve were decreased(n=18, perop 120+/-20, postop 108+/-26cm/sec, 0.010.05). Peak velocities of pulmonic valve were significantly decreased(n=17, perop 168+/-46, postop 104+/-51cm/sec, p<0.0005). 3) PDA Peak velocities of mitral valve were significantly decreased when compared perop. with postop. echocardiogram(n=29, perop 138+/-28, postop 111+/-19cm/sec, p<0.0005). Tricuspid valve velocities showed no significant changes between preop. and postop. echocardiogram (n=15, perop 47+/-12, postop 44+/-10cm/sec, p>0.05). Aortic valve velocities showed no significant changes (n=10, perop 134+/-23, postop 121+/-25cm/sec, p>0.05). Peak velocities of pulmonic valve were significantly decreased(n=28, perop 138+/-37, postop 107+/-27cm/sec, p<0.005). This study demonstrates that Doppler echocardiographic assessment of velovity changes are correlated with known hemodynamic data and also will be a good index in the evaluation of operation.

Some of the proteins of mycobacteria are preferentially associated with the cell wall and are powerful immunogens, and humoral antibody responses to these mycobacterial antigens may occur in patients with tuberculosis. In this study, Triton X-100 solubilized protein (TSP) antigen was isolated from Mycobacterium tuberculosis H37Rv by overnight shaking with 1% Triton X- 100/PMSF and 10-90% ammonium sulfate precipitation. IgG and IgM antibody levels against TSP, crude protein from the unheated cultrue filtrate (CF#) and 30 kDa antigens were determined in the sera of 80 patients with pulmonary tuberculosis and 99 healthy controls with PPD (+) and (-). High IgG reactivity to TSP and CF antigen was observed in tuberculosis patients. Mean IgG antibody titers against all of three mycobacterial antigens were differed significantly (P<0.01) between patients and controls but IgM showed no difference. By the cut-off value adding 2 standard deviation to the mean absorbance of controls, the sensitivity and specificity of the IgG antibody to TSP antigen were 93.9% and 77.5%. The specificity to TSP antigen was a litttle higher than those obtained by CF and 30 kDa antigen. From the above results, the TSP antigen may be useful for the serodiagnosis of tuberculosis.

BACKGROUND: Acute renal failure (ARF) is a common postoperative complication after the cardiac surgery. Postoperative ARF have various causes, and are combined with other complications rather than being the only a complication. It deteriorates the general condition of the patient, and makes it difficult to manage the combined complications by disturbing the adequate medication and fluid therapy. We have planned this study to evaluate the effects of postoperative ARF after the on-pump coronary artery bypass surgery (CABG) on the recovery of patients and identify the risk factors. Method and Material: We reviewed the medical records of patients who underwent CABG with cardiopulmonary bypass by a single surgeon from Jan. 2000 to Dec. 2002. We checked the preoperative factors; sex, age, history of previous serum creatinine over 2.0 mg/dL, preoperatively last checked serum creatinine, diabetes, hypertension, left ventricular ejection fraction, intraoperative factors; whether the operation is an emergent case or not, cardiopulmonary bypass time, aortic cross clamp time, the number of distal anastomosis, postoperative factors; IABP. Then we have studied the relations of these factors and the cases of postoperative peak serum creatinine over 2.0 mg/dL. RESULT: There were 19 cases with postoperative peak serum creatinine over 2.0 mg/dL in a total 97 cases. Dialysis were done in 3 cases for ARF with pulmonary edema and severely reduced urine output. There were 8 cases (42.1%) with combined complications among the 19 patients. This finding showed a significant difference from the 5 cases (6.4%) in the patients whose creatinine level have not increased over 2.0 mg/dL. The mortalities are different as 1.3% to 10.5%. The risk factors that are related with postoperative serum creatinine increment over 2.0 mg/dL are diabetes, the history of previous serum creatinine over 2.0 mg/dL and left ventricular ejection fraction. CONCLUSION: Postoperative ARF after the on-pump CABG is related with preoperative diabetes, the history of previous serum creatinine over 2.0 mg/dL and left ventricular ejection fraction. Postoperative ARF could be the reason for increased rate of complications and mortality after on-pump CABG. Therefore, in the patients with these risk factors, the efforts to prevent postoperative ARF like off-pump CABG should be considered.

BACKGROUND: In the Korean Red Cross Blood Center, ABO blood typing are routinely performed only via red cell grouping at blood donations sites. However, when an error occurs in this process, it is impossible to issue a blood product contrary to the result of the blood type of the Blood Laboratory Center, thereby resulting in delayed supply. Therefore, efforts are needed to reduce typing errors at blood donation sites. METHODS: We analyzed 656,786 donor screenings between January 1, 2016 and December 31, 2016;we also analyzed the statistical data of donor ABO typing between 2013 and 2015. To reduce ABO typing error, we notified and trained nurses at Busan, Gyeongnam, Ulsan, and Daegu-Gyeongbuk Blood centers in June, 2016. We tried to confirm the improvement of ABO typing error at blood donation sites by comparing ABO typing before and after training. For data comparison, chi-square test was conducted (95% confidence interval, 0.05 significant level). RESULTS: The blood typing error rate was significantly lower (P=0.003) four months after training (0.005%) than before training (0.015%), and the blood typing error rate was significantly higher for the first blood donor (P<0.001). CONCLUSION: Educational training for nurses at blood donation sites may be effective in reducing ABO typing error. Continuous and regular training seems to be needed in future to reduce ABO typing error.
