우측 심장에 발생한 감염성 심내막염은 전체 감염성 심내막염의 5%를 차지하며 이중 70%이상에서 선천성 심기형이나 후천성 판막질환 등에 동반되어 발생한다. 환자들은 약물 남용의 과거력을 갖는 경우가 많으며, 혈액투석 등 의인성 감염성 심내막염이 발생하는 경우도 있다. 우측 심장에 발생한 감염성 심내막염은 항생제 치료에 대한 반응이 우수하고, 내과적 치료에 반응하지 않더라도 판막손상이나 색전에 의한 합병증이 상대적으로 적게 발생하기 때문에 수술이 필요하지 않은 경우가 많다. 만성신부전으로 혈액투석을 받는 환자들은 관혈적 투석경로를 통해 균혈증에 노출되고 이로 인해 감염성 심내막염이 속발된다. 본 교실에서는 혈액투석을 받던 말기신부전 환자에서 정맥내 도관과 관련하여 삼첨판막이나 폐동맥판막의 침범없이 우심방내 우종을 동반한 심내막염이 발생하였으며, 항생제 치료를 시행하였으나 반응이 없어 수술을 시행하였다. 속목정맥도관과 관련된 우측 심장의 감염성 심내막염은 혈액투석환자에서 매우 드물게 발생하지만 진단이 지연되고 이로 인해 적절한 시기에 치료를 받지 못하여 병원내 사망률을 높이므로 적극적인 진단과 처치가 필요함을 확인할 수 있었기에 이를 문헌고찰과 함께 보고하는 바이다.

Myocardial fibrosis (MF) is the result of persistent and repeated aggravation of myocardial ischemia and hypoxia, leading to the gradual development of heart failure of chronic ischemic heart disease. Triptolide (TPL) is identified to be involved in the treatment for MF. This study aims to explore the mechanism of TPL in the treatment of MF. The MF rat model was established, subcutaneously injected with isoproterenol and treated by subcutaneous injection of TPL. The cardiac function of each group was evaluated, including LVEF, LVFS, LVES, and LVED. The expressions of ANP, BNP, inflammatory related factors (IL-1β, IL-18, TNF-α, MCP-1, VCAM1), NLRP3 inflammasome factors (NLRP3, ASC) and fibrosis related factors (TGF-β1, COL1, and COL3) in rats were dete cted. H&E staining and Masson staining were used to observe myocardial cell inflammation and fibrosis of rats. Western blot was used to detect the p-P65 and t-P65 levels in nucleoprotein of rat myocardial tissues. LVED and LVES of MF group were significantly upregulated, LVEF and LVFS were significantly downregulated, while TPL treatment reversed these trends; TPL treatment downregulated the tissue injury and improved the pathological damage of MF rats. TPL treatment downregulated the levels of inflammatory factors and fibrosis factors, and inhibited the activation of NLRP3 inflammasome. Activation of NLRP3 inflammasome or NF-κB pathway reversed the effect of TPL on MF. Collectively, TPL inhibited the activation of NLRP3 inflammasome by inhibiting NF-κB pathway, and improved MF in MF rats.

Purpose: The purpose of this study is to review the indications of ankle lateral complex reconstruction using tendon graft. Materials and Methods: We searched PubMed using the index, "ankle, instability, lateral ligament, reconstruction" from 1990 to present (September 30, 2015). We excluded 1) modified Brőstrom operation (MBO), 2) conventional tenodesis surgery, 3) review article, 4) technical note, and 5) articles written in another foreign language. We reviewed 24 papers through the publication events, operational method, the indications of surgery, and the specific features of the patient group. Results: There were the indications of 1) previous ligament surgery failure, 2) situation when ligament repair is impossible due to the ligament defect, 3) severe instability (preoperative talar tilt >$15^{\circ}$, anterior draw >10 mm or the difference of contralateral side talar tilt >$5^{\circ}$, anterior draw >3 mm), and 4) overweight (body mass index >$30kg/m^2$). Other considerations included 1) generalized joint laxity and 2) workers, highly-demanded or athlete highly-affected by instability. Conclusion: The ankle lateral complex reconstruction using tendon graft could be indicated in patients with the possibility of MBO failure with several considerations.

Cardiac fibrosis is a common feature in chronic hypertension patients with advanced heart failure, and endothelial-to-mesenchymal transition (EndMT) is known to promote Angiotensin II (Ang II)-mediated cardiac fibrosis. Previous studies have suggested a potential role for the transcription factor, ETS-1, in Ang II-mediated cardiac remodeling, however the mechanism are not well defined. In this study, we found that mice with endothelial Ets-1 deletion showed reduced cardiac fibrosis and hypertrophy following Ang II infusion. The reduced cardiac fibrosis was accompanied by decreased expression of fibrotic matrix genes, reduced EndMT with decreased Snail, Slug, Twist, and ZEB1 expression, as well as reduced cardiac hypertrophy and expression of hypertrophy-associated genes was observed. In vitro studies using cultured H5V cells further confirmed that ETS-1 knockdown inhibited $TGF-{\beta}1$-induced EndMT. This study revealed that deletion of endothelial Ets-1 attenuated Ang II-induced cardiac fibrosis via inhibition of EndMT, indicating an important ETS-1 function in mediating EndMT. Inhibition of ETS-1 could be a potential therapeutic strategy for treatment of heart failure secondary to chronic hypertension.

Objectives : To identify target areas and set priorities among those areas identified for national quality evaluation. Methods : Target areas were identified from: i) analysis of the national health insurance claims data, mortality and prevalence data ii) various group surveys, including representatives from 22 medical specialty associations, 19 physician associations, QI staffs in hospital, civil organizations, and commissioners of Health Insurance Review and Assessment Service(HIRA) ⅲ) literature reviews and RAM(RAND/UCLA appropriateness method). The priority areas for national quality evaluation represented the full spectrum of health care and the entire life span. The criteria for selecting the priority areas were impact, improvability, and measurability. The priority areas were divided into three categories : short-term, mid-term, long-term. Results: Based on the group surveys and the data analysis, 46 candidates were selected as quality evaluation priority areas. 13 areas were selected as having a short-term priority areas: tuberculosis, community acquired pneumonia, stroke, ischaemic heart disease, diabetes, hypertension, chronic lower respiratory disease(asthma, chronic obstructive pulmonary disease), intensive care unit, emergency room, nosocomial infection, use of antibiotics, multiple medication and renal failure. This results suggested that we need to enlarge the target priority areas to the chronic diseases in short-term. Conclusions: The priority areas identified from the study will assist healthcare quality associated institutions as well as HIRA in selecting quality evaluation areas. It is required to develope and implement strategies for improving the quality of care within the next 5 years.

We evaluated the inappropriateness of metformin use in patients with type 2 diabetes and chronic medical conditions to identify the frequency of the prescription metformin in violation of the food and drug administration (FDA) black box warning. We reviewed medical records of 307 outpatients who received metformin at endocrinology department in a hospital setting between January 1, 2005 and August 30, 2009. Of the 307 outpatients, 25 discontinued treatment of metformin due to elevated serum creatinine level (Scr${\geq}$1.5 mg/dl in male, Scr${\geq}$1.4 mg/dl in female), cancers, and/or liver disease. 5 were lost to follow-up. 89 (29.0%) of the patients had cardiovascular disease, 54.1% for hypertension, 9.8% for liver disease, and 60 (20.8%) for chronic kidney disease. 12 patients (3.9%) with chronic kidney disease and/or elevated serum creatinine level, and 1 patient (0.3%) with lactic acidosis were contraindicated to metformin use. Metformin should be avoided in 7 outpatients (2.3%) with active hepatitis and 1 patient (2.6%) with liver cirrhosis. Of the 307 outpatients, 13 (4.2%) patients who received metformin at the first visit and 16 (8.7%) patients who received metformin at the last visit violated to black box warning. 8 (2.6%) of the patients were in precautionary conditions to metformin use. Adjusted mean difference of serum creatinine was -0.16 mg/dl [95% CI: -0.22 to -0.11 (p<0.05)] and adjusted mean difference of alanine aminotransferase was 4.46 IU/l [95% CI: 2.47 to 6.44 (p<0.05)] between the first visit and the last visit. Critical number of elderly patients who are at the high risks of drug-disease and drug-laboratory interaction is exposed to the inappropriate metformin use in violation of black box warning. The periodic evaluation of metformin use and monitoring prescription through drug utility review (DUR) system is needed to improve patients' safety and to reduce adverse drug events.

This study aimed to describe the prevalence of comorbidities associated with chronic obstructive pulmonary disease (COPD) and their relation with relevant outcomes. A systematic review based on the PRISMA methodology was performed from January 2020 until July 2021. The MEDLINE, Lilacs, and Scielo databases were searched to identify studies related to COPD and its comorbidities. Observational studies on the prevalence of comorbidities in COPD patients and costs with health estimates, reduced quality of life, and mortality were included. Studies that were restricted to one or more COPD pain assessments and only specific comorbidities such as osteoporosis, bronchitis, and asthma were excluded. The initial search identified 1,409 studies and after applying the inclusion and exclusion criteria, 20 studies were finally selected for analysis (comprising data from 447,459 COPD subjects). The most frequent COPD comorbidities were: hypertension (range, 17%-64.7%), coronary artery disease (19.9%-47.8%), diabetes (10.2%-45%), osteoarthritis (18%-43.8%), psychiatric conditions (12.1%-33%), and asthma (14.7%-32.5%). Several comorbidities had an impact on the frequency and severity of COPD exacerbations, quality of life, and mortality risk, in particular malignancies, coronary artery disease, chronic heart failure, and cardiac arrhythmias. Comorbidities, especially cardiovascular diseases and diabetes, are frequent in COPD patients, and some of them are associated with higher mortality.

배경: 만성 폐색전증은 초기에 비특이적인 증상으로 인해 진단이 쉽지 않을 뿐만 아니라 국내에서도 흔한 질환이 아니므로 보고된 예도 적다. 본 연구에서는 만성 폐색전증 환자에서 폐동맥 내막절제술의 수술결과를 후향적인 방법으로 분석해보았다. 대상 및 방법: 1996년부터 2008년까지 만성 폐색전증으로 본원에서 수술받았던 환자를 대상으로 하였다. 만성적인 호흡곤란을 주소로 내원한 환자들은 심초음파, 흉부 전산화 촬영, 폐 관류스캔을 이용하여 진단하였다. 결과: 7예의 환자에서는 정중흉골 절개술로, 1예는 좌측 후측방 절개술을 통해 접근하였다. 4예에서는 극저체온 순환 정지하에, 3예는 심실 세동하에, 1예는 심정지하에 폐동맥 내막절제술을 시행하였다. 술후 평균 폐동맥 수축기 혈압은 술 전 $78.9{\pm}14.5\;mmHg$에서 $45.6{\pm}17.6\;mmHg$로 의미 있게 감소하였고(p=0.000) 삼첨판 부전증 정도는 Grade II 이하였다. 조기사망은 2예가 있었으며 그 중 1예는 폐동맥 고혈압이 지속되면서 우 심부전이 호전되지 않아 결국 사망한 경우였다. 결론: 만성 폐색전증의 예후는 아주 불량한 것으로 알려져 있다. 그러나 조기에 적절한 진단과 우 심부전이 심해지기 전에 적절한 수술적인 치료를 한다면 향후 환자의 삶의 질을 향상시킬 수 있을 것으로 보인다.
