Acute ECG ST-segment elevation mimicking myocardial infarction in a patient with pulmonary embolism
Pulmonary embolism is a common cardiovascular emergency, but it is still often misdiagnosed due to its unspecific clinical symptoms. Elevated troponin concentrations are associated with greater morbidity and mortality in patients with pulmonary embolism. Right ventricular ischemia due to increased right ventricular afterload is believed to be underlying mechanism of elevated troponin values in acute pulmonary embolism, but a paradoxical coronary artery embolism through opened intra-artrial communication is another possible explanation as shown in our case report
Propensity score matching in estimating the effect of managerial education on academic planning behavior. Study design: a cross-sectional study
<p>Abstract</p> <p>Background</p> <p>In many academic settings teaching a particular topic is applied to every student enrolled in the same academic year, it is a difficult task for researchers to design a randomized control group study. This research aimed to estimate the effect of teaching management and planning on increasing academic planning behavior (APB), using propensity score matching (PSM).</p> <p>Methods</p> <p>In a cross-sectional survey utilizing a self-reported structured questionnaire on a systematic random sample of 421 students in Hanoi Medical University, one of the eight medical schools in Vietnam, this evaluation study adopted regression procedures to assess model fit, then PSM to create a matched control group in order to allow for evaluating the effect of management education.</p> <p>Results</p> <p>The study showed both direct and indirect effects of the education on behavior. After PSM to adjust for the possible confounders to balance statistically two groups - with and without management education, there is statistically a significant difference in APB between these two groups, making a net difference of 18.60% (p < .05). The estimated 18.6 percentage point increase can be translated into the practice of APB by 670 students in the population. This number of academic planners can be attributed to a high recall of important management and planning education.</p> <p>Conclusions</p> <p>The study provided theoretical as well as practical implications to guide the design of the education and evaluation of teaching.</p
Repair of long-gap esophageal atresia: gastric conduits may improve outcome—a 20-year single center experience
Massive pulmonary embolism with ST elevation in leads V1–V3 and successful thrombolysis with tenecteplase
A 42 year old woman was referred to the emergency department from the radiology department after having a syncopal episode during a triplex examination of the lower extremities for acute painful right leg swelling five hours earlier that morning. She had no significant medical history, smoked 3–5 cigarettes a day, and had been taking contraceptive medication for menorrhagia for the preceding three months. On presentation she was cyanotic, dyspnoeic, and haemodynamically unstable. ECG showed sinus tachycardia of 120 beats/min with ST elevations from V1 through V3 mimicking anteroseptal acute myocardial infarction. Ten minutes after presentation she was thrombolysed with 80 mg tenecteplase leading to ST elevation resolution and remarkable haemodynamic recovery after 20 minutes. This case shows how pulmonary embolism can mimic anteroseptal acute myocardial infarction on ECG and the life saving results from rapid thrombolysis with tenecteplase
Use of an Amoeba proteus model for in vitro cytotoxicity testing in phytochemical research. Application to Euphorbia hirta extracts.
Amoeba proteus is proposed as a low-cost multi-purpose biochemical tool for screening and standardizing cytotoxic plant extracts with possible application in the laboratories of developing countries. Advantages and limitations of this test are examined and different mathematical treatments (probit analysis versus curve fitting to Von Bertalanffy and Hill functions) are investigated. Known anti-cancer (doxorubicin, daunorubicin, dacarbazine, 5-fluorouracil) and antiparasitic (emetine, dehydroemetine, metronidazole, cucurbitine, chloroquine) drugs were tested using this method and only metronidazole appeared inactive. Application of this model to Euphorbia hirta established that a 100 degrees C aqueous extraction of fresh aerial parts allows efficient extraction of active constituents and that drying the plant material before extraction considerably reduces activity.Journal ArticleResearch Support, Non-U.S. Gov'tinfo:eu-repo/semantics/publishe
Inter-university harmonization of undergraduate and graduate education in psychiatry. Consensus statement of the Hellenic College of Academic Psychiatry
The rapid changes in the field of psychiatry and the demands of the European and other international organizations responsible for training in psychiatry, create an indisputable need to harmonize the educational programs of the various Greek medical schools, and to reach an inter-university agreement as to what should be included in the psychiatric education curriculum of the medical student and of the psychiatric trainee. The Hellenic College of Academic Psychiatry (HCAP) was constituted as an inter-university organization having as one of its aims to coordinate efforts to modernize and harmonize the academic educational programs in psychiatry in Greece. In this article the process followed by the HCAP members is presented and the final consensus texts reached for undergraduate and postgraduate training in psychiatry
