BACKGROUND: Tight control of blood pressure in patients with coronary artery disease is critical, especially in the setting of long-standing hypertension and left ventricular dysfunction. With off-pump coronary artery bypass graft (CABG), hypertension usually occurs after the sternotomy, along with an increase in heart rate and filling pressure. In order to minimize hypertension during this period, nitroglycerin or nicardipine was prophylactically infused. METHODS: Twenty patients scheduled to undergo an off-pump CABG from April to August, 2001, were selected and divided into two groups. Group I (n = 10) received nicardipine and Group II (n = 10) received nitroglycerin. Before the skin incision, nicardipine (0.5 - 1.0ng/kg/min) or nitroglycerin (0.5 - 1.0ng/kg/min) was continuously infused. Mean arterial pressure (MAP), heart rate (HR), mean pulmonary artery pressure (mPAP), pulmonary artery occlusion pressure (PAOP), cardiac index (CI), and the systemic vascular resistance index (SVRI) were repeatedly measured at the stages of preincision, postincision, poststernotomy, pericardium open, and 10 min after reperfusion. RESULTS: Although MAP after the sternotomy was increased compared with preincision, it remained within a normal range. Similarly, HR, mPAP, and PAOP were all within a normal range despite increases. The CI was within a normal range at all stages in both groups, and there were no significant difference between the two groups. In group I, the SVRI was significantly decreased compared with group II when pericardium was opened. CONCLUSIONS: Both nicardipine and nitroglycerin were effective in preventing or attenuating hypertension after sternotomy with the hemodynamic stability.

BACKGROUND: Pringle maneuver and nitroglycerin (NTG) administration to reduce hemorrhage during hepatectomy may affect renal blood flow (RBF) and renal cortical perfusion (RCP) by reducing blood pressure (BP), perload and others. However, so far there have been no studies on RBF and RCP changes during and after hepatic vascular maneuver in hepatectomy. The purpose of this study was to evaluate the changes in RBF and RCP along with low dose (2 microgram/kg/min) NTG with or without low dose (3 microgram/kg/min) dopamine after the occlusion and reperfusion of hepatic blood flow. METHODS: Eighteen mongrel dogs were divided into three groups according to drug administration after hepatic reperfusion; control group (group C, n = 6), NTG group (group N, n = 6), and NTG with dopamine group (group N-D, n = 6). After femoral arterial and central venous catheterization, a midline abdominal incision was made, and the hepatic artery (HA) and the portal vein (PV) were exposed for clamping and declamping. Thereafter, the right renal artery was exposed, and a doppler probe for measuring RBF was placed around the right renal artery, and a thermal diffusion microprobe was inserted in the renal outer cortex to measure RCP. Hemodynamics, RBF and RCP, were repeatedly measured before and after HA and PV reperfusion. RESULTS: No significant change in heart rate was observed in any group. The BP decreased in all the groups after HA and PV occlusion. In group C, the BP recovered to the baseline level after hepatic reperfusion but not in groups N and N-D. The RBF and RCP decreased in all groups after HA andPV occlusion. The RBF increased compared to baseline in N-D after hepatic reperfusion, and the RCP increased versus baseline in N-D, 10 minutes after hepatic reperfusion. CONCLUSIONS: In conclusion, it was observed that the RBF and RCP increased compared to baseline by administering dopamine during HA and PV reperfusion. Therefore, the prophylactic administration of low dose dopamine during hepatectomy offers an effective method of protecting renal function.

Spontaneous native aortic valvular thrombosis is an uncommon event that usually results from cardiac catheterization, bacterial endocarditis or a hypercoagulable state. We report here on a case of native valvular thrombus that was incidentally detected as masses that caused aortic stenoinsufficiency during routine follow-up, and the patient was without any of the previously described precipitating factors. The patient underwent aortic valvular surgery for removal of the aortic valvular mass. The pathological findings of the aortic valve showed organized valvular thrombus without evidence of any tumor.

PURPOSE:Rapidly progressive glomerulonephritis (RPGN) is characterized by the rapid increase in serum creatitnin and crescents formation involving more than 50% of glomeruli. 10 patients who had been treated for RPGN were studied retrospectively for thier underlying diseases and clinical features. METHOD: Cilinical review was performed on 10 children who were diagnosed with RPGN by clinical features and renal biopsy and followed up at department of pediatrics during the last 10 years, from May 1990 to May 2000. RESULT: There were 6 males and 4 females between the ages of 2.1 and 14.3 years (mean 10.9+/-.8). 3 had Henoch-Sch nlein purpura nephritis; 2, idiopathic rapidly progressive glomerulonephritis; 2, lupus nephritis; 1, hemolytic uremic syndrome; 1, membranous glomerulonephritis and 1, microscopic polyangiitis. The most common chief complaints were gross hematuria and oliguria. Initial clinical features included proteinuria, edema, hypertension, nausea and arthralgia. Mean serum BUN was 74.2+/-39.1 mg/dL; mean serum creatinin, 3.2+/-1.8 mg/dL and mean creatinin clearance, 26.5+/-13.2 mL/min/1.73m2. Antineutrophil cytoplasmic antibody was positive only in microscopic polyangiitis. ANA and Anti-DNA antibody were positive in two lupus nephritis patients. Serum complements were decreased in 4 patients. All patients except Hemolytic uremic syndrome received steroid pulse therapy and immunosupressive agents. 3 patients were performed acute peritoneal dialysis and 2 patients were given plasmapheresis. At the last follow up, 1 patient was dead, 4 patients had elevated serum creatinin, 2 of these 4 patients were on chronic ambulatory peritoneal dialysis and 6 patients had normal renal function. CONCLUSION: Rapidly progressive glomerulonephritis is a medical emergency that requires very rapid diagnosis, classification, and therapy. Appropriate therapy selected on the basis of underlying disease mechanism can substantially improve renal survival.

Purpose: In Korea, the Act on Hospice and Palliative Care and Decisions on Life-Sustaining Treatment (LST) was implemented on February 4, 2018. We aimed to investigate relevant factors and clinical changes associated with LST decisions after law enforcement. Materials and Methods: This single-center retrospective study included patients who completed LST documents using legal forms at Asan Medical Center from February 5, 2018, to June 30, 2020. Results: 5,896 patients completed LST documents, of which 2,704 (45.8%) signed the documents in person, while family members of 3,192 (54%) wrote the documents on behalf of the patients. Comparing first year and following year of implementation of the act, the self-documentation rate increased (43.9% to 47.2%, p=0.014). Moreover, the number of LST decisions made during or after intensive care unit admission decreased (37.8% vs. 35.2%, p=0.045), and the completion rate of LST documents during chemotherapy increased (6.6% vs. 8.9%, p=0.001). In multivariate analysis, age < 65 (odds ratio [OR], 1.724; 95% confidence interval [CI], 1.538 to 1.933; p < 0.001), unmarried status (OR, 1.309; 95% CI, 1.097 to 1.561; p=0.003), palliative care consultation (OR, 1.538; 95% CI, 1.340 to 1.765; p < 0.001), malignancy (OR, 1.864; 95% CI, 1.628 to 2.133; p < 0.001), and changes in timing on the first year versus following year (OR, 1.124; 95% CI, 1.003 to 1.260; p=0.045) were related to a higher self-documentation rate. Conclusion Age < 65 years, unmarried status, malignancy, and referral to a palliative care team were associated with patients making LST decisions themselves. Furthermore, the subject and timing of LST decisions have changed with the LST act.

PURPOSE: Congenital adrenal hyperplasia(CAH), which is classified into salt-wasting, simple virilization and non-classic type according to clinical features, is difficult to detect in early stages. Failure to diagnose it in the initial state may lead to life-threatening adrenal crisis, inappropriate male sex assignment in the genetic female, acceleration of skeletal maturation and subsequent short stature. Therefore, we studied the variables increasing the 17-hydroxyprogesterone(OHP) values for more specific and sensitive diagnosis of CAH. METHODS: We classified 3,532 newborns into variable factors; gestational age, birth weight, gender, delivery type, sampling date and stress. Then, we analysed the relationships between 17-OHP values and variable factors. RESULTS: The mean value of 17-OHP was 4.21+/-0.03ng/ml. There were significant differences among the variable factors except gender. The mean value of male was 4.26ng/ml, and that of female was 4.15ng/ml(P=0.10). The mean value of 17-OHP in vaginal delivered newborn was higher than C-section delivered ones(4.71ng/ml, 3.34ng/ml, P=0.0001). It was also higher in low birth weight(P=0.0001), in prematurity(P=0.001), those sampled within 4 days(P=0.0001), stressful condition and ventilator care-assisted(P=0.004). CONCLUSION: 17-OHP value in neonatal screening is influenced by several variables such as vaginal delivery, ventilator management, low birth weight, sampling date and prematurity. If the 17-OHP value is increased, we have to consider the variables influencing the increase in value and follow up with time interval or analysis of genetic mutations.
