Clinical manifestations of the brucellosis may show extensive appearance because of its wide signs and symptoms. Patients with brucellosis are usually symptomatically treated by using different antibiotics at private clinics due to misdiagnosis of clinical laboratory findings specially those chronic forms. These subjects will have been hospitalized with a complicated form of signs after changin...

Transactional Lock Elision (TLE) uses Hardware Transactional Memory (HTM) to execute unmodified critical sections concurrently, even if they are protected by the same lock. To ensure correctness, the transactions used to execute these critical sections “subscribe” to the lock by reading it and checking that it is available. A recent paper proposed using the tempting “lazy subscription” optimiza...

Trapping methods can strongly influence the sampling of mammal communities. This study compared the efficiency of the capture of small mammals in Sherman traps in two positions (at ground level and in trees) and pitfall traps in a fragmented landscape. Trapping sessions were carried out between October 2008 and October 2009 at two fragments (8 and 17 ha), an agroforest corridor between them, an...

One is not required to be a mechanical engineer to drive a car and, considering the advanced state of mechanical engineering, most people limit their interest in what lies “under the hood” to finding a competent mechanic. Users of evaluation, risk, and decision analysis tools that are based on classical decision theory should be aware that, as is demonstrated below, classical MCDA (multi-criter...

Objectives: To present a number of cases in which pitfalls may occur during the performance of epidural block, so that they may be prevented and corrected during the procedure. Materials and methods: A retrospective analysis was performed in 118 patients who suffered from lumbar pain, radicular pain or both and who underwent CT-guided minimally invasive anti-inflammatory analgesic treatment by ...

Association mapping can be viewed as an application of population genetics and evolutionary biology to the problem of identifying genes causally connected to phenotypes. However, some population-genetic principles important to the design and analysis of association studies have not been widely understood or have even been generally misunderstood. Some of these principles underlie techniques tha...

make for the interpretations of findings and the implications thereof for educational practice and future research. A new section of Perspectives on Medical Education, entitled Statistical points and pitfalls, directly tackles these analytical issues. The overall purpose of this series is to help readers and researchers alike increase awareness of how to use statistics, why and how we fall into...

To the Editor: We would like to share with you several “pitfalls” in infection control that we have experienced at our 300bed referral center. Despite our education efforts in category-specific isolation, we have observed healthcare students (ie, student nurses or respiratory therapists) violating our isolation guidelines. Healthcare students often are not taught the importance and rationale of...

Correlation is a mine eld for the unwary. One does not have to search far in the literature of nancial risk management to nd misunderstanding and confusion. This is worrying since correlation is a central technical idea in nance. Correlation lies at the heart of the capital asset pricing model (CAPM) and the arbitrage pricing theory (APT), where its use as a measure of dependence between nancia...

Arthroscopy of the wrist is a well-established procedure; however complications, problems and difficulties are possible. The complication rate is estimated to be about 2%, of which equipment failure is probably the most frequent. Injury of the overlying tendons, nerves and even the radial artery has also been described. The anatomy of certain wrists can cause considerable difficulties in obtain...
