  • The perfect cardiac catheterization technique, including good diagnostic and therapeutic qualities, without risk and with no recovery time for the patient, does not exist. Obtaining initial access to the arterial circulation is the first and most frequent catheterization difficulty encountered by the interventional cardiologist during the procedure. Often, it is also the only difficult part of the exam for the patient because it may cause a vagal reaction or painful spasm.

A careful history and examination is key, as are special investigations such as CXR, ECG and pulse oximetry. An echocardiogram is the gold standard investigation required to confirm the diagnosis.

  • Electrocardiograms (ECGs) are the graphic representation of body surface potential differences generated by the electrical activity of the heart. Bipolar limb leads, augmentedunipolar limb leads and precordial leads have been used routinely for recording the ECG, which remains an essential part of the cardiac examination, even after the advent of cardiac catheterization, angiocardiography, echocardiography and many other sophisticated diagnostic modalities.

  • Permanent pacemaker implantation can be done in the cardiac catheterization laboratory or in the operating room. Both locations have unique advantages and disadvantages. The operating room often has better lighting and thus allows better visualization of the device pocket, but fluoroscopy can be less optimal in the operating room, which generally utilizes a C-arm radiology device. Sterility was once thought to be more advantageous than the operating room setting. Data support that infection rates tend to be extremely low in both settings.

  • If a patient has previously undergone a hysterectomy, the cervix is usually no longer present and only a vaginal cuff remains. If the pathology was benign, then the patient no longer requires Pap smears (11). However, if the hysterectomy was performed for cervical cancer or dysplasia, cervical cancer screening on the vaginal cuff should continue since remnants of cervical tissue may be present. These women are also at higher risk for vaginal in- traepithelial neoplasia (VAIN) and vaginal cancer.

  • If some forms of independent production have worked closely in unison with Hollywood, others have operated in areas in which Hollywood has chosen not to tread, sometimes teaching valuable lessons to the dominant institution. Necessity has often driven independent operators to be the pioneers of American cinema, exploring new avenues in their search for territories not already colonized by the major studios. The early independents took cinema to parts of rural America, including the gold camps of Alaska, that were not served by the big companies.

  • The cellular damage due to the hypoxi/re-oxigenative stress may trigger the production of free radicals with consequent destabilization of the cell membranes (Calandrella et al., 2010). As a matter of fact literature data show that the ischemic insult at retinal level activates iNOS which leads to the production of nitrogen oxide (Goldstein et al., 1995; Geyer et al., 1995): this compound is cytotoxic at high concentration and causes lipid peroxidation (Crow et al., 1996; Ullrich et al., 2000).

For the purposes of this document, measures with clinical context are presented with the effectiveness measures. Other measure sets describe health care delivery and systems issues and are discussed together.

  • It is important to recognize that risk-taking is an integral part of many financial institutions’ business models. This is a crucial difference to some domains that we have examined. Also, we are well aware that outside domains may not provide ready guidance to all aspects of financial services (see Appendix). This report concentrates on stylized patterns and lessons that are potentially transferable to the financial sector while acknowledging that no domain is perfect at managing risk or indeed fully comparable to financial services.

  • Another method for the detection of live trypanosomes in blood is by the use of ion exchange columns. The ion exchange gel is packed into plastic syringe bodies and the trypanosomes are collected in sealed Pasteur pipettes. After centrifugation, the pipette tip while immersed in a very shallow water bath, is examined with a 20 X objective. Trypanosomes may be seen undulating in the fluid within the pipette tip. The method is claimed 98% accurate, but requires more apparatus, preparation and skill development time.

  • The third section deals with neuroprotection. As we have discussed above, this has become a kind of Holy Grail for stroke scientists. Contributors to this section reviewed the state of the art in this quest or reported their experience in exploring novel ways of neuroprotection. Their work will be a useful addition to the store of knowledge that the modern Parsifal will exploit to finally find his Grail.

However, there are some safeguards in place to help protect investors. For example, a mutual fund’s assets must be held separately by a third party called a custodian. This is usually a chartered bank or trust company. Also, an independent auditor reviews and reports on the fund’s financial statements each year.
