BACKGROUND: Little information exists concerning the amount of information patients aspects from physicians as to the risk for an adverse reaction of medication. The present study was designed to determine such opinions in a population sample and to determine whether patients believe Physicians should use discretion in the amount of such information given. METHODS: Five hundred fifty sequential adults visiting outpatient clinics filled out a 9-item questionnaire. The percentage of subjects desiring information about varying degrees of risk and those believing physicians should and should not use discretion in the amount of such information provided were recorded. The results were correlated with demographic variables and Previous experience of adverse effects. RESULTS: Among the respondents, 56.6% desired to be told of all possible adverse effects; 13.8% only if an adverse effect occurred in 1 out of 100,000; and 26.3% only if such occurrence was 1 in 100, 3.3% were not interested in any information. The Percentages were closely similar to those for the same question that restricted opinion to serious adverse effects. The opinion that physicians should give the same information to all patients comprised 41.8% of the sample, and 83.4% opinioned that physicians were never justified in withholding any information. CONCLUSIONS: Many individuals desire all information concerning possible adverse effects of prescribed medication from physicians and agree that the Physician use judgement on the amount of information given, but do not consider the physician to be justified in withholding information.

BACKGROUND: Several kinds of stents have shown their safety and efficacy to treat acute or subacute closure after balloon angioplasty as well as to reduce restenosis rate. However, one of the limitations of stents is difficult to deploy especially in tortuos vessels, lesions at a bend, and distal to previously deployed stents. The Micro stent II, which was one of the most recently developed stents, ia a rapid-exchage balloon expandable stainless steel stent with a zigzag design connected with a continuous single weld in each 3mm segments. It scores over excellent trackability and optimum radio-opacity. Therefore, it is easy to operate and feasible in tortuous, distal lesions and variety of lesion lengths. We report our experiences with Micro-II stent implanatation in the first 76 patients at Tonsei cardiovascular center to assess its safety and efficacy in patients with complex coronary anatomy and clinical results in the first months. METHODS: Between January 1996 and July 1996, eighty-six Micro-II stent were implanted in the coronary arteries of 76 patients(male 65.8%, age 59+/-10 year). Forty-five patients had unstable angina, the others had stable angina(17pts), acute myocardial infarction(14pts). RESULTS: 1) Indication of stenting was de novo 51(59.3%), suboptimal result 25(29.1%), restenosis 1(1.2%) and 9(10.4%) of lesions were stented in bail out situation. 2) Single stent were implanted in 76(88.4%)lesions, overlapping stent in 10(11.6%)lesions. Among overlapping stents, the second stent with Micro-II stent and with another kind of stent were 4.6%, 7.0%, respectively. 3) Procedure related complication including a subacute closure was occurred in 1(1.2%) patient who had distal dissection and 45% residual stenosis. In 12(14%) lesions, preistent dissection has been noticed after stent impantation. 4) Angiographic success(defined as a residual stenosis of <30% without major dissection) was achieved in 82 of 86 attempts(95.3%). The procedual success rate(defined as a residual stenosis of <30% without occurrence of major clinical events within 4 weeks after procesure) was 96.1%(73/76 patients). Angiographic success and procedural success rate in calcified lesion were 100% and 100%, respectively. Angiographic success and procedural success rate in more than 45` angulated lesion were 97% and 100%, respectively. 5) The mean minimal luminal diameter of the target lesions was increased from 0.42+/-0.40mm before stent implantation to 2.93+/-0.50mm(p<0.001). The percentage of diameter stenosis was reduced from 86.49+/-13.04% to 1.40+/-7.11%(p<0.001) after stent implantation. CONCLUSION: Coronary stenting with AVE Micro-II stent can be safety performed and is particularly beneficial in tortuous and calcified arteries. There was a high tendency for peristent dissection which need to special consideration to avoid. Follow-up data is needed to assess mid and term patency. Coronary artery disease . AVE Micro-II stent . Immediate results.

Purpose: This study aimed to investigate the frequency of BRCA testing and related factors among young breast cancer patients (age < 40 years) in South Korea. Materials and Methods: We conducted a nationwide retrospective cohort study using data from the Health Insurance Review and Assessment claims. Newly diagnosed breast cancer patients younger than 40 were included. Annual BRCA testing ratios (number of BRCA test recipients/the number of patients undergoing breast cancer surgery in each year) were analyzed by region and health care delivery system. We investigated the location of breast cancer diagnosis and BRCA testing. Results: From January 2010 to December 2020, there were 25,665 newly diagnosed young breast cancer patients, of whom 12,186 (47.5%) underwent BRCA testing. The BRCA testing ratios increased gradually from 0.084 (154/1,842) in 2010 to 0.961 (1,975/2,055) in 2020. Medical aid (vs. health insurance) and undergoing surgery in metropolitan cities or others (vs. Seoul), general hospitals, and clinics (vs. tertiary hospitals) were associated with a lower likelihood of BRCA testing. While 97.8% of the patients diagnosed in Seoul underwent BRCA testing in Seoul, 22.9% and 29.2% of patients who were diagnosed in metropolitan areas and other regions moved to Seoul and underwent BRCA testing, respectively. Conclusion The frequency of BRCA testing has increased over time in South Korea, with Seoul showing a particularly high rate of testing. About one-quarter of patients diagnosed with breast cancer outside of Seoul moved to Seoul and underwent BRCA testing.

Purpose: Tumescent in nipple-sparing mastectomy (NSM) has been reported to increase the risk of necrosis by impairing blood flow to the skin flap and nipple-areolar complex. At our institution, we introduced a tumescent-free robotic NSM using the da Vinci single-port system (Intuitive Surgical, Inc.). Methods: We conducted a retrospective analysis of patients who underwent tumescent-free robotic NSM between October 2020 and March 2023 at Asan Medical Center (Seoul, Korea). Clinicopathological characteristics, adverse events, and operative time were evaluated. Results: During the study period, 118 patients underwent tumescent-free robotic NSM. Thirty-one patients (26.3%) experienced an adverse event. Five patients (4.2%) were classified as grade III based on the Clavien-Dindo classification and required surgery. The mean total operative time was 467 minutes for autologous tissue reconstruction (n = 49) and 252 minutes for implants (n = 69). No correlation was found between the cumulative number of surgical cases and the breast operative time (P = 0.30, 0.52, 0.59 for surgeons A, B, C) for the 3 surgeons. However, a significant linear relationship (P < 0.001) was observed, with the operative time increasing by 13 minutes for every 100-g increase in specimen weight. Conclusion Tumescent-free robotic NSM is a safe procedure with a feasible operative time and few adverse events.
