Aim: To evaluate precancerous lesions such as hyperplasia and endometrial polyps in obese postmenopausal women. Materials and Methods: Women who were referred with abnormal uterine bleeding in postmenopausal period or the presence of endometrial cells on cervical cytology in our department were investigated. Anthropometric measurements such as height, weight, body mass index, waist/hip ratio and endometrial thickness were compared between a precancerous lesion (hyperplasia and endometrial polyp) group and a pathologically normal group. Results: We detected statistically significant thickening of endometrium in patients with precancerous lesions. Moreover patients with precancerous lesions had higher body mass index than the pathologically normal group. Conclusions: We found elevated precancerous lesion rates in overweight and obese women in the postmenopausal period, of interest given that the prevalence of obesity is increasing in most parts of the world. Although screening for endometrial cancer is not recommended for the general population, in high-risk populations like obese postmenopausal women, it may be very important.

In Western patient populations, the reported incidence of imaging-demonstrated deep vein thrombosis (DVT) after total hip arthroplasty (THA) is as high as 70% without prophylaxis. The reported rates of symptomatic pulmonary embolism (PE) after THA in recent studies range from 0.6% to 1.5%, and the risk of fatal PE ranges from 0.11% to 0.19% in the absence of prophylaxis. Predisposing factors to DVT in western patients include advanced age, previous venous insufficiency, osteoarthritis, obesity, hyperlipidemia, dietary and genetic factors. However, Asian patients who have undergone THA have a strikingly low prevalence of DVT and virtually no postoperative PE. Some authors suggest low clinical prothrombotic risk factors and the absence of some DVT-related genetic factors in Asian patient populations decrease the risk of DVT, PE or both. In Korea, the prevalence of DVT after THA without thromboprophylaxis have ranges from 6.8% to 43.8%, and asymptomatic PE have ranges from 0% to 12.9%; there have been only two reported cases of fatal PE. Deep-wound infections resulting from postoperative hematomas or prolonged wound drainage have been reported with routine thromboprophylaxis. The prevalence of DVT differs varies based on patient ethnicity. Guidelines for the use of thromboprophylaxis were altered and focus on the potential value of outcomes compared with possible complications (e.g., bleeding).

Inflammatory bowel disease (IBD) is an immune-mediated chronic inflammatory intestinal condition. With development of various treatment options for IBD, 5-aminosalicylic acid (5-ASA) agents became the drugs of choice due to high efficacy and low risk of complication, specifically effective at inducing and maintaining remission in ulcerative colitis(UC). Pancytopenia caused by 5-ASA agents, especially by mesalazine, has been rarely reported compared with azathioprine, which is commonly used for glucocorticoid-dependent IBD and known to have risk of bone marrow suppression. In the present report, we describe the case of a 57-year-old woman diagnosed with UC, who developed pancytopenia due to adverse effect of mesalazine after recovery from azathioprine-induced pancytopenia. After withdrawal of mesalazine, the laboratory values consistent with myelosuppression continued for 3 months while pancytopenia from azathioprine remained only for 2 weeks. Since pancytopenia can be fatal due to its risk of severe bleeding and infection, close monitoring of clinical presentation is important when starting mesalazine and laboratory data should be evaluated whenever the patients present related symptoms. Furthermore, we suggest that complete blood cell counts should be considered when resuming mesalazine following the development of pancytopenia from any cause, as routinely recommended for azathioprine use.

목 적: EBV의 초감염과 면역억제의 강도는 소아 간이식에서 PTLD 발생의 주요 위험인자로 알려져 있다. 삼성서울병원에서 6년간 경험한 PTLD 5례의 임상양상을 분석해보고자 한다. 대 상: 1996년부터 2002년 6월까지 41례의 소아간이식 환아를 대상으로 하였는데 이중 7명이 사망하였고, PTLD로 사망한 1명을 포함한 35명을 대상으로 분석하였다. 방 법: 공여자의 EBV 항체가 양성이고 수혜자가 음성일 경우 고위험군으로, 그 외의 경우를 저위험군으로 정의하였다. 위험군 분류, 면역억제제 종류, 간이식이 행하여진 나이, 수술 후 PTLD 진단까지의 기간, 수술 후 EBV 항체의 양전 시기, 거부반응에 대한 치료 여부, PTLD의 증상들인 발열, 설사, 빈혈, 장출혈 식욕부진 저알부민혈증 등의 발현 여부를 후향적으로 조사하였다. 결 과: 1) PTLD는 전체 소아 간이식 환아 41명 중 5명에서 발생하였다(12.2%). 고위험군은 16명으로 이 중 5명(31.3%)에서 PTLD가 발생하였고 저위험군 19명중에서는 한 명도 발생하지 않았다. 2) 사망례를 제외한 4명은 tacrolimus로 면역억제 치료를 받았으며 수술 당시 나이는 평균 10.8개월이었고 수술 후 PTLD 진단까지 평균 9.8개월이 걸렸 다. EBV 양전 시기는 수술 후 평균 6개월이었다. 3) 사망례를 포함한 5명 중 3명에서 PTLD 진단 이전에 간이식 거부반응이 있었고 스테로이드 pulse 치료 등 면역억제를 증가시키는 치료를 행하였었다. 4) 한 명에서 쉰 목소리 증상이 발견되어 조직검사 상 후두 PTLD와 장 PTLD로 진단하였고 나머지 네 명은 모두 혈변이 있었으며 대장 조직검사 상 장 PTLD로 진단하였다. 5) 빈혈과 저알부민 혈증은 모든 환아에서 나타나고 있었고 발열, 설사, 장출혈이 5명 중 4명에서 보였으며 식욕부진은 5명 중 3명에서 나타났다. 결 론: 10%가 넘는 발병률을 보이는 PTLD는 소아 간이식 후 매우 중요한 합병증으로서 특히 EBV의 고위험군에서 31%에 이르는 발병률을 가지고 있는 바 이들에 대하여 EBV 상태와 면역억제 유지에 대한 철저한 대비가 있어야 할 것으로 생각된다. 특히 빈혈, 저알부민혈증, 발열, 설사, 장출혈 등이 동반할 때에는 PTLD를 의심해 볼 수 있다. PTLD의 공통적인 발병양상으로는 첫째, 공여자가 EBV 양성이고 수혜자가 음성이면서, 둘째, EBV가 수술 후 6개월 경 양전되며, 셋째, 1세 전후에 수술을 시행하고 넷째, 간이식 거부반응을 겪으면서 면역억제의 강도가 높아졌을 경우 등이다.

Purpose: Low birth weight (LBW) is one of the major public health problems in India. Hence, there is a need to identify risk factors that, when modified, will reduce the burden of unhealthy children on the healthcare system. The objective of this study was to determine whether periodontitis among mothers in the rural population of India is a risk factor for LBW babies. Methods: A hospital-based case control study was conducted among 340 postpartum mothers. The cases consisted of 170 women who had given birth to babies weighing <2,500 g, while the control group consisted of 170 women who had given birth to babies weighing ${\geq}2,500g$. Details of the mothers were taken from the hospital records and through a personal interview, and a full-mouth periodontal examination was performed postpartum, which included probing depth, clinical attachment level, and bleeding on probing on six sites per tooth. Results: LBW cases had a significantly worse periodontal status than the controls, having an odds ratio (OR) of 2.94 (P=0.01). The multivariate logistic regression model demonstrated that periodontal disease is a significant independent risk factor with an adjusted odds ratio (aOR) of 2.85 for the LBW group (95% confidence interval [CI], 1.62-5.5). Other factors showing significant associations with LBW were pre-eclampsia (aOR, 4.49; 95% CI, 1.4-14.7), preterm labor (aOR, 5.5; 95% CI, 3.2-9.9), and vaginal type of delivery (aOR, 2.74; 95% CI, 1.4-5.2). Conclusions: Periodontitis represents a strong, independent, and clinically significant risk factor for LBW. Periodontal therapy should form a part of the antenatal preventive care among rural women in India.

Background: Acute promyelocytic leukemia (APL) is a distinctive clinical, biological and molecular subtype of acute myeloid leukemia. However, data from Pakistan are scarce. Therefore we reviewed the demographic and clinical profile along with risk stratification of APL patients at our center. Materials and Methods: In this descriptive cross sectional study, 26 patients with acute promyelocytic leukemia were enrolled from January 2011 to June 2015. Data were analyzed with SPSS version 22. Results: The mean age was $31.8{\pm}1.68years$ with a median of 32 years. The female to male ratio was 2:1.2. The majority of our patients had hypergranular variant (65.4%) rather than the microgranular type. The major complaints were bleeding (80.7%), fever (76.9%), generalized weakness (30.7%) and dyspnea (15.38%). Physical examination revealed petechial rashes as a predominant finding detected in 61.5% followed by pallor in 30.8%. The mean hemoglobin was $8.04{\pm}2.29g/dl$ with the mean MCV of $84.7{\pm}7.72fl$. The mean total leukocyte count of $5.44{\pm}7.62{\times}10^9/l$; ANC of $1.08{\pm}2.98{\times}10^9/l$ and mean platelets count were $38.84{\pm}5.38{\times}10^9/l$. According to risk stratification, 15.3% were in high, 65.4% in intermediate and 19.2% in low risk groups. Conclusions: Clinico-epidemiological features of APL in Pakistani patients appear comparable to published data. Haemorrhagic diathesis is the commonest presentation. Risk stratification revealed predominance of intermediate risk disease.

Objective: Direct current cardioversion for atrial fibrillation could be associated with the risk of thromboembolic events. Anticoagulation therapy with warfarin (INR 2.0-3.0) is recommended 3 weeks before and 4 weeks after cardioversion to reduce the risk of thromboembolism. This study evaluated warfarin therapy in pharmacist-managed anticoagulant services (ACS). Methods: This retrospective study was performed in 106 patients with atrial fibrillation from 2012 to 2013. The primary efficacy endpoint was the composite of stroke, transient ischemic attack, myocardial infarction, and cardiovascular death. The primary safety measure was major bleeding. To evaluate the peri-procedural effects of warfarin treatment, we studied whether target INR was maintained, as well as the maintenance period of the therapeutic range. Quality of treatment was measured by time in therapeutic range (TTR) by using the Rosendaal method. Results: There were no thromboembolic events, but TEE examination at time of cardioversion showed a left atrial thrombus in three patients (2.8%). Bleeding complications after cardioversion occurred in 2 patients (1.9%). The average INR value at the time of cardioversion was $2.59{\pm}0.8$, and was within the therapeutic range in 83 patients (78%). Analysis of the patients in whom the value was within the therapeutic range twice consecutively showed that the ratio of TTR was 80% and the therapeutic range was maintained in 67 patients (63%) for an average of 4.90 weeks prior to cardioversion. Similarly, 76 patients (72%) had a stable INR within the therapeutic range for an average of 5.70 weeks and a mean TTR of 83%. Conclusion: Pharmacists significantly contributed to appropriate warfarin treatment with close monitoring during cardioversion. Likewise, active pharmacist monitoring and systemic management should be considered to reduce thromboembolism and bleeding complications in the peri-cardioversion period.

Objective We compared the predictive value of the National Early Warning Score+Lactate (NEWS+L) score with those of other parameters such as the pre-endoscopic Rockall score (PERS), Glasgow-Blatchford score (GBS), and albumin, international normalized ratio, altered mental status, systolic blood pressure, age older than 65 years score (AIMS65) among patients with upper gastrointestinal bleeding (UGIB). Methods We conducted a retrospective study of patients with UGIB during 2 consecutive years. The primary outcome was the composite of in-hospital death, intensive care unit admission, and the need for ${\geq}5$ packs of red blood cell transfusion within 24 hours. Results Among 530 included patients, the composite outcome occurred in 59 patients (19 inhospital deaths, 13 intensive care unit admissions, and 40 transfusions of ${\geq}5$ packs of red blood cells within 24 hours). The area under the receiver operating characteristic curve of the NEWS+L score for the composite outcome was 0.76 (95% confidence interval, 0.70 to 0.82), which demonstrated a significant difference compared to PERS (0.66, 0.59-0.73, P=0.004), but not to GBS (0.70, 0.64-0.77, P=0.141) and AIMS65 (0.76, 0.70-0.83, P=0.999). The sensitivities of NEWS+L scores of 3 (n=34, 6.4%), 4 (n=92, 17.4%), and 5 (n=171, 32.3%) were 100%, 98.3%, and 96.6%, respectively, while the sensitivity of an AIMS65 score of 0 (n=159, 30.0%) was 91.5%. Conclusion The NEWS+L score showed better discriminative performance than the PERS and comparable discriminative performance to the GBS and AIMS65. The NEWS+L score may be used to identify low-risk patients among patients with UGIB.

배경: 기계 심장판막 대치술 후 발생하는 혈전성 합병증을 방지하기 위해 항응고제 치료로써 와파린을 환자에게 투여한다. 이때 환자에 따른 적절한 와파린 용량을 결정하기 위한 지표로서 INR을 참고하는데 통상 대동맥판막은 $2.0{\sim}3.0$, 승모판막은 $2.5{\sim}3.5$가 참고치로서 받아들여지고 있다. 하지만 임상 경험상 대부분의 환자에서 이 수치로 유지하였을때 출혈성 합병증(비출혈, 혈뇨, 자궁출혈, 뇌출혈 등)이 빈번하게 발생하여 참고치보다 더 낮게 유지하는 경우가 많다. 이에 본원에서는 기계 심장판막 환자들을 후향적으로 조사하여 혈전성 합병증의 빈도가 낮은 적정한 INR을 알아보고자 한다. 대상 및 방법: 1984년 1월부터 2007년 2월까지 이엽성 기계 심장판막 대치술을 받고 생존한 311명의 환자를 대상으로 후향적으로 조사하였다. 대동맥판막치환 환자들(60명)은 INR $1.5{\sim}2.0$ (1군), $2.0{\sim}2.5$ (2군), 2.5 (3군) 이상의 세 군으로 나누고 승모판막치환(171명)이나 승모판막과 대동맥판막을 동시에 치환한 환자들(80명)은 INR $1.5{\sim}2.0$ (1군), $2.0{\sim}2.5$ (2군), $2.5{\sim}3.0$ (3군), 3.0 (4군) 이상의 네군으로 나누어 혈전성 합병증 발생률, 중요출혈성합병증 발생률을 조사하여 각각의 생존함수를 비교하였다. 결과: 대동맥 판막치환 환자 중 혈전성 합병증은 2명, 출혈성합병증은 4명이 발생하였고 세군의 혈전성 합병증의 생존함수의 차이는 관찰되지 않았고 출혈성 합병증의 생존곡선에서 1, 2군과 3군의 차이가 관찰되었다. 승모판막치환이나 승모판막과 대동맥판막을 동시에 치환한 환자들 중 혈전성 합병증은 13명, 출혈성 합병증은 15명이 발생하였고 네 군의 혈전성 합병증의 생존함수의 차이는 관찰되지 않았고 출혈성 합병증은 1, 2군과 3, 4군에서 차이를 보였다. 결론: 모든 판막에서 INR이 $1.5{\sim}2.5$ (1군과 2군)로 유지한 환자들이 그 이상으로 유지한 환자들보다 혈전성 합병증에서 차이를 보이지 않았고 출혈성 합병증에서 유의하게 감소하는 양상을 보여 이엽성 기계판막에서 적정한 INR은 $1.5{\sim}2.5$로 유지하는 것이 바람직하다고 판단된다.

Nonsteroidal antiinflammatory drugs (NSAIDs) are used in the treatment of extensive diseases related to various symptoms; inflammation, pain and fever. NSAIDs work by blocking prostaglandin synthesis, but adverse drug events (ADEs) have been increasing dramatically such as gastrointestinal bleeding, perforation and stenosis, a kind of serious ADEs. Therefore, NSAID-related ulcer complication guidelines have been announced containing various risk factors and symptoms. Thus, this study aims to evaluate of NSAID usage and appropriateness for prevention of NSAID-related ulcer complication based on American journal of gastroenterology (AJG) guideline 2009. Further, the study suggests Korean guideline for prevention of NSAID-related ulcer compared to AJG guideline. For this study, data was collected through electronic medical record (EMR) at Seoul national university of Bundang hospital. The primary end point was a composite of NSAID-related ulcer risk factor, types of NSAIDs, co-prescribed NSAID ulcer prevention drugs and NSAID-related ulcer after taking NSAID. The risk factors include over 65 years, high dose NSAID, previous ulcer history and taking drugs (e.g. aspirin, anticoagulant and steroid) causing ulcer. If a patient has 3 or 4 factors, that patient was classified high risk group. And if 1 or 2 factors that patient was classified moderate risk group. The patient who has no risk factor was in low risk group. I studied 8,120 patients who received NSAID from 1 January 2009 to 31 December 2009. High risk group was 16(0.2%), moderate risk group was 4,364(53.7%), and low risk group was 3,740(46.1%). The results show that high risk group should be prescribed COX-2 inhibitors with ulcer prevention drugs, and moderate or low risk group need traditional NSAIDs with ulcer prevention drugs. This may be different with 2009 AJG guideline because AJG guideline suggested taking COX-2 inhibitor alone in moderate group or taking traditional NSAID alone in low risk group could get higher ulcer complication. The results indicated that choosing preventive drug is important in case that how many risk factors the patients have. The proper drugs would be helpful for safe and effective NSAID usage in each patient group.
