Purpose: To investigate adverse drug reactions (ADR) and causative drugs in the elderly 65 years of age or older, using Korean spontaneous reporting adverse events reporting database from June 2009 to December 2010. Methods: We estimated the association between ADRs and implicated medications by calculating a proportional reporting ratio (PRR), reporting odds ratio (ROR), and information component (IC). We reexamined the most frequently implicated medications and ADRs, and the seriousness of ADRs. Then, we assessed reports and concordant rate of ADRs due to medications designated as "high-risk" in elderly by 2012 healthcare effectiveness data and information set (HEDIS) or "potentially inappropriate" by 2012 American Geriatrics Society updated Beers criteria for potentially inappropriate medications (PIMs). Results: Among 15,484 elderly reports, data-mining analysis by PRR, ROR and IC showed that 421 drug-ADR pairs were detected as signals (3,189). The most frequently reported ADR and causative drug were urticaria (470) and contrast media agents (647), respectively. One hundred eighty nine ADR cases were graded as serious. Twenty-two kinds of high-risk medications were shown to be implicated in only 0.9% of ADRs. Only thirty-nine cases were consistent with 2012 Beers criteria or HEDIS. Conclusion: These results suggest that management of the other medications including contrast media agents as well as close monitoring of PIMs are necessary for reducing ADRs in the elderly.

연구배경 : 전세계적으로 약제 내성 결핵에 대한 관심이 높ㅇ지고 있다. 일차 내성 결핵의 유병률은 수년 간의 국가 결핵 관리 체계를 평가하는 역학적 지표로 사용된다. 저자들은 내성 결핵에서의 사회경제적 인자를 포함한 임상적 특정에 대해 평가하고자 하였다. 방법 : 1995년 3월부터 2000년 2월까지 이대목동병원에서 내성 결핵으로 진단 받은 환자 중 조사가 가능했던 68명을 대상으로 하였다. 결과 : 일차 내성 결핵 환자는 획득 내성 결핵환자보다 평균 연령이 더 젊고(39.6$\pm$16.3yr vs. 48.2$\pm$16.5yr ; p<0.05), 40대 미만 연령층의 구성비가 더 높았으며(62.9% vs. 36.4% ; p<0.05), 고학력자가 더 많았다 (38.9% vs. 11.1% ; p<0.05). 획득 내성 환자는 일차 내성 환자보다 통계학적 의의는 없었으나 가족력의 빈도가 더 높고 자가 주택이 없는 경우가 더 많았다. 획득 내성 환자는 일차 내성 환자보다 침범된 폐엽의 수가 더 많았고(2.0$\pm$0.8 vs. 1.4$\pm$0.7; p<0.01), 총 치료 기간이 더 길었다(18.3$\pm$7.2 months vs. 10.6$\pm$6.3 months ; p<0.05). 획득 내성 환자가 일차 내성 환자보다 통계학적 의의는 없었으나 내성 약제의 수가 더 많고 입원률이 더 낮았으며 임의로 투약을 중단하는 경우가 더 많았다. 일차 내성 환자가 획득 내성 환자보다 단일 약제 내성률이 더 높은 반면, 복수 약제 내성률과 다제 내성률은 더 낮았다. 약제별 내성률에서 isoniazid에 대한 내성률이 가장 높았고, 획득 내성 환자에서 일차 내성 환자보다 isoniazid에 대한 내성률이 유의하게 높았다(90.9% vs. 71.4% ; p<0.05). 결론 : 획득 내성 환자가 낮은 사회경제적 계층의 비율이 높은 반면, 일차 내성 환자는 젊고 활동적인 집단인 것으로 보인다. 약제 내성 결핵의 전파와 재발을 막기 위해서는 내성 환자의 적절한 격리와 적극적인 추적 관찰을 통한 치료의 종결이 중요하다.

주파수 인피던스를 이용하는 ThetaProbe ML2x인 ADR 형식의 토양함수비센서를 적용하여 주문진 표준사, 상주 화강 풍화토, 장수 편마암풍화토을 대상으로 실험을 수행하였다. 시험의 목적은 측정센서의 측정 정밀도를 측정로드부 삽입 깊이에 따른 변화 양상을 파악하였다. 흙매질은 체적함수비 함량과의 관계를 비교하기 위하여 건조상태와 습윤상태로 구분하여 수행하였다. 측정결과에서 측정로드부가 흙매질 내 5cm 이상 삽입되면 측정전압의 변화폭이 크게 감소하는 것을 파악하였다. 또한, 표준사와 같이 균질한 입자를 가진 흙보다는 점토와 실트 등과 같은 세립질을 함유한 화강풍화토와 편마암풍화토에서 측정전압이 안정적인 형태를 갖는 것으로 나타났다. 따라서, 측정치는 측정로드부가 다공질매질과의 접촉 면적이 커질수록 안정적인 값을 제공한다.

Background/Aims: Adverse drug reaction (ADR) is an appreciably harmful or unpleasant reaction, resulting from an intervention related to the use of a medicinal product. The present study was conducted in order to monitor the frequency and severity of ADR during antimicrobial therapy of septicemia. Methods: A prospective, observational, and noncomparative study was conducted over a period of 6 months on patients of septicemia admitted at a university hospital. Naranjo algorithm scale was used for causality assessment. Severity assessment was done by Hartwig severity scale. Results: ADRs in selected hospitalized patients of septicemia was found to be in 26.5% of the study population. During the study period, 12 ADRs were confirmed occurring in 9, out of 34 admitted patients. Pediatric patients experienced maximum ADRs, 44.4%. Females experienced a significantly higher incidence of ADRs, 66.7%. According to Naranjo's probability scale, 8.3% of ADRs were found to be definite, 58.3% as probable, and 33.3% as possible. A higher proportion of these ADRs, 66.7% were preventable in nature. Severity assessment showed that more than half of ADRs were moderate. Teicoplanin was found to be the commonest antimicrobial agent associated with ADRs, followed by gemifloxacin and ofloxacin. Conclusions: The incidence and severity of ADRs observed in the present study was substantially high indicating the need of extra vigilant during the antimicrobial therapy of septicemia.

클로자핀은 치료 저항성 조현병 약물치료의 "최적 표준(gold standard)"으로 받아들여지고 있다. 클로자핀은 다른 항정신병약물에서 흔히 나타나는 추체외로 증후군, 지연이상 운동증을 거의 일으키지 않고 고프로락틴의 일시적인 상승만 보이는 한편, 발열 등의 약물 이상반응이 흔하게 나타난다. 치료 시작 시기에 드물게 무과립구증, 신경이완제 악성증후군과 같은 치명적인 부작용과 연관된 발열이 발생할 수 있으며, 이 경우 클로자핀을 즉시 중단해야 한다. 그러나 발열의 양성 원인은 생명을 위협하는 부작용보다 훨씬 빈번하므로 치료 시작 시기에 발열을 보이는 경우 무조건 클로자핀을 중단하는 것은 타당하지 않다. 또한, 치료 유지 시기에도 언제든지 발열은 발생할 수 있다. 특히 폐렴의 위험은 시간이 지남에 따라 감소하지 않으며, 클로자핀은 다른 항정신병약물 보다 폐렴의 위험이 높으므로 항상 이를 염두에 두고 치료제 모니터링을 통하여 약물 용량을 결정하는것이 권장된다.

This study identifies the common problems faced by the owners of strata titles, the Management Corporation, the Joint Management Body, the Commissioner of Building (COB) as well as the Managing Agent being the stakeholders in managing strata properties. The methods employed are qualitative in nature. Analysis is done based on reports published by the relevant authorities dealing with strata residential properties as well as the case law as reported in the two leading journals in Malaysia such as the Malayan Law Journal and the Current Law Journal. The types and nature of problems are derived from the annual reports. The extent of the problems is determined based on the figures and supported by observation and interviews with the COB, being the agency directly involved in overseeing and monitoring strata properties management. The findings show that a substantial number of problems exist in the management of strata properties despite a law that allows the owners to self-managed their own properties. Having stated the status quo concerning the problems, the study also looks at the various means of resolving disputes as exist under the Malaysian housing system. The study proposes that alternative dispute resolution (ADR) modes are more appropriate in ensuring the sustainability of strata living and management.

The aim of this study was to investigate the effect of resveratrol on the pharmacokinetics of nifedipine in rats. The pharmacokinetic parameters of nifedipine were measured after the oral administration of nifenipine (6 mg/kg) in the presence or absence of resveratrol (0.5, 2.5 and 10 mg/kg, respectively). The effect of resveratrol on the P-glycoprotein (Pgp), CYP 3A4 activity was also evaluated. Resveratrol inhibited CYP3A4 enzyme activity in a concentration-dependent manner with 50% inhibition concentration ($IC_{50}$) of 0.94 ${\mu}M$. In addition, resveratrol significantly enhanced the cellular accumulation of rhodamine 123 in MCF-7/ADR cells overexpressing P-gp. Compared to the control groups, the presence of 2.5 mg/kg and 10 mg/kg of resveratrol significantly (p<0.05, p<0.01) increased the area under the plasma concentrationtime curve (AUC) of nifedipine by 49~75%, and the peak concentration ($C_{max}$) of nifedipine by 48~66%. The absolute bioavailability (AB%) of nifedipine was significantly (p<0.05) increased by 22.9-34.8% compared to the control (19.8%). The terminal half-life ($T_{1/2}$) of nifedipine was significantly (p<0.05) increased compared to the control. While there was no significant change in the time to reach the peak plasma concentration ($T_{max}$) of nifedipine in the presence of resveratrol. It might be suggested that resveratrol altered disposition of nifedipine by inhibition of both the CYP3A and P-glycoprotein efflux pump in the small intestine of rats. In conclusion, the presence of resveratrol significantly enhanced the oral bioavailability of nifedipine, suggesting that concurrent use of resveratrol or resveratrol-containing dietary supplenment with nifedipine should require close monitoring for potential drug interation.
