PURPOSE: This study was to analyze health behavior adherence and identify affecting factors on the duration of the hypertension diagnosis. METHODS: A total of 154 patients of hypertension participated in this study. Data were collected from October to December, 2013 and analyzed using frequency, t-test, ANOVA, multiple linear regression. RESULTS: The scores of health behavior adherence and hypertension knowledge in incidental hypertension patients were 82.23±9.69, 17.86±4.33, respectively. In the treated hypertension patients, the scores of health behavior adherence were 89.30±10.17 and hypertension knowledge were 18.54±3.89. The selected independent variables explained 34% of the health behaviors in the incidental hypertension patients and 36% of the health behaviors in the treated hypertension patients. The regression models were statistically significant (F=4.37, p < .001, F=4.45, p < .001). Among selected potential influencing factors, age (β=.423, p < .001), smoking habit (β=−.227, p=.038), obesity (β=.369, p=.030), hypertension knowledge (β=.281, p=.007), coping strategies (β=.261, p=.015). affect health behavior adherence in the incidental hypertension. In the treated hypertension patients were age (β=.362, p=.007), sex (β=−.396, p=.004), smoking habit (β=−.245, p=.022), perceived health status (β=−.238, p=.035) affect health behavior adherence. CONCLUSION: There was difference about health behavior adherence between newly diagnosed and treated hypertension patients. So different approaches for incidental and treated hypertensive patient need to improve health behavior through tailored nursing intervention.

Purpose: The purpose of this study was to prepare guidelines for the treatment of COVID-19-positive hip fractures based on the treatment experience of patients with COVID-19-positive hip fractures admitted to a COVID-19-dedicated hospital. Materials and Methods: A retrospective analysis was performed on COVID-19-positive elderly hip fracture patients treated at a COVIDdedicated hospital when the number of domestic COVID-19 infections increased rapidly. The treatment results were analyzed by comparing the complications of patients who underwent surgery at a COVID-dedicated hospital and those who did not, the time taken from surgery to surgery, and the number of visits to medical institutions. Results: The average surgery time for COVID-19 hip fracture patients in the author’s hospital was 3.74 days from the date of injury, and it took an average of 12.8 days for surgery at other hospitals. The average number of patients who visited medical institutions was 3.33 locations in the group who did not undergo surgery at the author’s hospital, which was significantly higher than the 2.83 locations in the group who had surgery. Among the patients unable to undergo surgery, no patient could not undergo surgery due to serious reasons. Conclusion The explosive increase in COVID-19 infections has delayed the time of surgery for COVID-19-positive elderly patients with hip fractures and increased the transfer rate of medical institutions, even for relatively non-dangerous causes. Clear criteria for treatment and effective policies are needed to prevent delay delays in treatment.

PURPOSE: To evaluate the accuracy of T2-weighted imaging and MR cholangiopancreatography using the single shot fast spin-echo technique for evaluating pancreaticobiliary disease. MATERIALS AND METHODS: B e t ween March and July 1997, axial and coronal T2-weighted images ( T E : 8 0 -2 00 msec) and MR cholangiopancreatograms(TE:800 -1 2 00 msec) were obtained in two ways [single slab (thickness:30 -50 mm) and multislice acquisition under chemical fat saturation] using SSFSE pulse sequencing in 131 cases of suspected pancreati-cobiliary disease. The accuracy of SSFSE MR imaging was assessed in 89 lesions of 74 patients [male,48; female,26; age range, 3 0 -86 (mean,59)years] confirmed surgicopathologically(50 lesions in 39 patients) and clinically (39 lesions in 35 patients). Two radiologists reviewed the MR images and diagnosis was determined by consensus. RESULTS: Correct diagnosis was confirmed in 84 of 89 lesions (94 %). Seven lesions were falsely interpreted, false positive and false negative results accounting for two and five cases, respective l y. Two pancreatic cancers were misdiagnosed as pancreatitis and a cancer of the proximal common bile duct(CBD) was interpreted as a distal CBD cancer. The sensitivity of SSFSE MR imaging for malignancy was 93 %. One CBD stone revealed by endoscopic retrograde cholangiopancreatography (ERCP) was not detected on MR images. In contrast, a stone in the CBD seen on MR images was not apparent on subsequent ERC P. Sensitivity and specificity for calculous disease were 96 % and 99.7 %, respective l y. A benign stricture of the ampulla of Vater was falsely interpreted as normal, and correct diagnosis was possible in two falsely diagnosed cases when MR images were rev i ewed retrospectively. CONCLUSION: The combination of T2-weighted and cholangiographic images using SSFSE is an accurate method for diagnosing pancreaticobiliary diseases.

PURPOSE: To evaluate the efficacy of acetic acid as a sclerosing agent by observation of histologic change in urinary bladder epithelium after the instillation of acetic acid. MATERIALS AND METHODS: Urinary bladder of the rabbit was catheterized with a Foley catheter, and acetic acid of 10%, 20%, 30%, 40% and 50% concentration was instilled for 5 minutes. After evacuation of the acid, the bladder was irrigated three times with normal saline. After two days, gross and histologic examinations of the bladder were performed. RESULTS: A bladder into which10% acetic acid had been instilled revealed a nearly normal epithelium without denudation. In two cases, 20% acetic acid was instilled; one revealed partial denudation of the epithelium and the other revealed complete denudation. Mild to moderate interstitial edema and vascular congestion of the bladder wall were evident in all cases in which acid at a concentration of 30% or more had been instilled. In all cases in which the concentration of acid was greater than 30%, the epithelium was completely denuded. CONCLUSION: An acetic acid concentration of 40% or more is sufficient to completely destroy the epithelium of rabbit urinary bladder, and may be effective as a new sclerosing agent in cases of renal or hepatic cyst.

Tumor angiogenesis was simulated using a two-dimensional computational model. The equation that governed angiogenesis comprised a tumor angiogenesis factor (TAF) conservation equation in time and space, which was solved numerically using the Galerkin finite element method. The time derivative in the equation was approximated by a forward Euler scheme. A stochastic process model was used to simulate vessel formation and vessel elongation towards a paracrine site, i.e., tumor-secreted basic fibroblast growth factor (bFGF). In this study, we assumed a two-dimensional model that represented a thin (1.0mm) slice of the tumor. The growth of the tumor over time was modeled according to the dynamic value of bFGF secreted within the tumor. The data used for the model were based on a previously reported model of a brain tumor in which four distinct stages (multicellular spherical, first detectable lesion, diagnosis, and death of the virtual patient) were modeled. In our study, computation was not continued beyond the 'diagnosis' time point to avoid the computational complexity of analyzing numerous vascular branches. The numerical solutions revealed that no bFGF remained within the region in which vessels developed, owing to the uptake of bFGF by endothelial cells. Consequently, a sharp declining gradient of bFGF existed near the surface of the tumor. The vascular architecture developed numerous branches close to the tumor surface (the brush-border effect). Asymmetrical tumor growth was associated with a greater degree of branching at the tumor surface.

PURPOSE: To evaluate the hemostatic effect of N-butyl 2-cyanoacrylate(NBCA) injection and RF electrocauterization of the tract after fine needle biopsy of the liver, and the histopathologic changes of the liver. MATERIALS AND METHODS: Three lobes of rabbit liver were selected and separately punctured four times with 21 gauge biopsy needles. According to the hemostatic procedure on fine needle biopsy, three groups (1, 2, 3) were formed : group 1, in which there was no maneuver for bleeding control, was the control group ; group 2, in which NBCA was injected into the puncture tract while slowly removing the needle ; group 3, in which RF electrocauterization of the tract was carried out. After completely removing the needle, each group was evaluated for amount of bleeding and histologic change. RESULTS: The amount of bleeding was 0.407gm+/-0.245 in group 1,0.028gm+/-0.036 in group 2 and 0.035gm+/-0.028 in group 3. As compared with the control group(group 1), injecting NBCA into the biopsy tract(P=0.0002) and RF electrocauterization of the tract(P=0.0003) significantly reduced the amount of bleeding after liver biopsy. The amount of bleeding was not statistically different between group 2 and 3, however (P=0.58). In Group 1, the tract was fully filled with blood. Group 2 showed NBCA embolized in the biopsy tract, adhering to hepatocytes and mixed with blood; small vessels adjacent to the puncture tract were filled with NBCA. Group 3 showed tissue degeneration, including necrosis of hepatocytes, vacuolation and neutrophil infiltration. CONCLUSION: Injection of NBCA and RF electrocauterization of the tract after puncture of the liver for biopsy efficiently controlled bleeding. In particular, the efficiency of NBCA injection was due to its effect of plugging the tract and causing the embolization of adjacent small vessels. With regard to procedural handling, RF electrocauterization of the tract is superior to injection of NBCA.

BACKGROUND: Irbersatan, an orally active antihypertensive agent, effectively reduce blood pressure by directly blocking angiotensin II receptors without any significant adverse effects. The purpose of this study is to evaluate the efficacy and safety of irbesartan in patients with mild to moderate hypertension. METHODS: This study enrolled 83 patients who had diastolic pressure above 95 mmHg and below 110 mmHg on two measurements. Sixty eight patients were administered 150mg of irbesartan, an angiotensin II receptor blocker, daily for four weeks as an initial dosage. If the sitting diastolic pressure was equal to or greater than 90 mmHg after a 4 week treatment period, the dosage was doubled until the end of 8 weeks. Baseline pressures, antihypertensive effect, side effects, laboratory findings were compared before and after treatment. RESULTS: Fourty two patients out of 53 patients having completed this study showed decreased blood pressure equal to or more than 5 mmHg of the sitting diastolic pressure (response rate=79%). Twenty one patients out of 53 patients showed normalized blood pressure below 90 mmHg of the sitting diastolic pressure (normalization rate=40%). The extent of decrease in diastolic and systolic blood pressure after eight week treatment was an average 11.7+/-10.1 mmHg and 16.3+/-18.9 mmHg, respectively (p<0.05). Nineteen ontoward side effects was observed in 17 patients out of 68 patients with medication (frequency of ontoward effects=25%). Only one case with headache was considered to be related to the medication. Abnormal laboratory findings were observed in eight patients, and only one case with elevation of bilirubin and ALT levels was considered to be related to the medication. CONCLUSION: In conclusion, irbesartan is a safe and effective antihypertensive drug in patients with mild to moderate hypertension with tolerable side effects.

Chylous ascites is a rare condition caused by various diseases and conditions that interfere with the abdominal or retroperitoneal lymphatics, and uncommonly it can manifest as a post-operative complication after abdominal, retroperitoneal or mediastinal surgery. Chylous ascites can be diagnosed by a high triglyceride content in ascites. The authors experienced a 5-year-old girl with congenital hepatic fibrosis who presented with chylous ascites after a splenorenal shunt operation, who was successfully managed by fasting and total parenteral nutrition, followed by a lipid-free diet with medium chain triglyceride supplementation. Here, the authors report this case of post-operative chylous ascites after a splenorenal shunt (Warren shunt) operation with a review of the pertinent literature.
