  • In addition to an in-depth knowledge and understanding of the scientific and clinical aspects, veterinary students also need to have a grasp of the legal, ethical and social elements of veterinary practice. Thus, communication and interpersonal skills; responsible and professional behaviour, and an understanding of the business context of veterinary practice are now recognized as important areas that should be incorporated into veterinary curricula.

  • Of the four heart valves, the mitral valve is the only valve that has a distinguishable annulus. However, the presence of a fibrous annular structure is variable and discontinuous. The firmest site of support for the mitral valve is the region of fibrous continuity between the aortic and mitral valves, the extent of which is delineated by the right and left fibrous trigones (Fig. 2). Nevertheless, for surgical purposes, the annulus is considered the area of attachment of the valve leaflets to the atrial muscle. The annulus is a functional component of the mitral valve.

  • In 1989, Hodge et al. published two papers in the Journal of Urology (Hodge et al., 1989a and 1989b). The first paper described directed transrectal prostate biopsies of palpable abnormalities, 90% of which had corresponding hypoechoic lesions on ultrasound (Hodge 1989a). Additional biopsies were also taken of isoechoic areas of the peripheral and central zones. These biopsies were not systematic and they were found to be positive in 66% of cases. The second article was a landmark paper which marked the start of the modern era of prostate needle biopsy (Hodge et al., 1989b).

  • The statistics are well known and staggering. And yet, in many countries the figures continue to worsen. Each year 500,000–600,000 women die in pregnancy and childbirth. In some parts of Sub–Saharan Africa, 1 in 6 women die in child birth, while in United States the lifetime risk is as low as 1 in 84001. HIV/AIDS statistics tell an equally disturbing story of dis- parity. In parts of Africa, over 35% of the adult population — 1 in 3 adults — is infected with HIV 2. The number of women contracting the disease is also on the rise.

  • The impact that physical and psychological violence have on the health of an older person is exacerbated by the ageing process and diseases of old age. It is more difficult for the elderly to leave an abusive relationship or to make correct decisions because of the physical and cognitive impairments that usually come with old age. In some places, kinship obligations and the use of the extended family network to resolve difficulties may also lessen the ability of older people, particularly women, to escape from dangerous situations.

  • A person who had the cancer and died 10 years later of the cancer would contribute an event, a death due to the cancer, having also contributed 10 person-years of survival time. A 90 % cancer specific survival at 10 years would mean that 90 % of patients had not died from their cancer, while 10 % had died from their cancer (Kaplan, 1958). Calculation of cause-specific survival is especially important when studying diseases with a favorable prognosis, as is the case at hand, where the patients live long enough to be exposed to other causes of death....

  • Again, however, an appropriate comparisons needs to take account of the fact that the SEC took place four years later and the process of cohort succession would affect results in the same way as was noted for literacy with respect to comparisons with the census. Thus when DHS results are calculated for persons aged 56 and older (who would be 60 and older in 2004) and limited to the provinces covered by the SEC sample, the percentages who ever attended school are reasonably similar in the two sources. Overall the comparison of basic demographic characteristics from the 2004...

  • Imagine. It’s 6:25 p.m. and you’ve just wrapped up a meeting. You still have several items on your “must-do” list before you can call it a night and a 25-minute commute that used to take as long as 90 minutes in the bad old days of rush-hour traffic. But no worries today. You flick open an app on your phone and request a pick-up at the office; a text confirmation comes back and a few minutes later a car pulls up. “Home,” you say, as you launch a call to your client in Shanghai. The car slips easily into the...

  • Bonfand borrows it from the philosopher Jean-Luc Marion (one of the most important thinkers of the French new wave in phenomenology), as particularly developed in In Excess: Studies on Saturated Phenomena, 2002 (originally published as: De surcroît. Etudes sur les phénomènes saturées, 2001). In Marion’s phenomenology of giveness, the saturated phenomenon refers to a kind of extreme phenomena which confront the perception and the condition of phenomenality to its limits.

  • A technique that carried less risk and could be performed as an office procedure was the method of needle biopsy of the prostate through the perineum. The first description came in 1922 from Barringer who adopted Martin and Ellis’ technique of needle puncture for acquiring tissue for histological analysis (Barringer, 1922). He described the use of a screw tip needle to obtain a perineal punch biopsy and was successful in obtaining prostatic tissue in 16 out of 33 patients.

  • In a series published by Peirson and Nickerson, one patient had 4 grams of tissue resected for histology during transurethral prostate biopsy and this was later found to be benign. However since DRE was suspicious for cancer a perineal punch biopsy with the Silverman needle was performed and this subsequently revealed malignancy (figure 7) (Peirson and Nickerson, 1943). Consequently Kaufman et al.

  • The sound in the urethra allowed the prostate to be directed posteriorly to facilitate palpation of the nodule and placement of the Silverman needle (Barnes & Emery, 1959). The patient would be anaesthetized and positioned in lithotomy. An initial digital rectal examination (DRE) was performed to ensure an empty rectum and an ounce of antiseptic solution was instilled per rectally for ten minutes. Agents used included Vioform (iodochlorhydroxyquin U.S.P) 3% Betadine (providone-iodine) or Triophyll (tri-iodophynol).

  • While wood and to some extent charcoal are the most common solid fuels used in developing countries, China and Mongolia have high household prevalence of coal, especially for heating in open portable space heaters, some with and some without chimney. Mestl et al. (2006), based on data from the China 2000 Population Census, report that about 60 percent of rural households used biomass as primary cooking fuel. Nearly 30 percent of rural households used coal as the primary fuel. Mestl et al model annual average population weighted exposure (PWE) to indoor air pollution by...

  • When evaluating the pruchase power of the population, additional variables than average income should be considered. In the case of Mexico, for instance, the purchasing power of many younger Mexicans is higher than income statistics might suggest at first sight: Unlike their Central European or North American counterparts, it is not uncommon for young Mexicans to stay in their parents’ home up to (or even beyond) the time when they get married. They thus save considerable amounts of money on rent which then is often spent on consumer goods....

  • Bone Marrow Examination A bone marrow aspirate and smear or a needle biopsy may be useful in the evaluation of some patients with anemia. In patients with hypoproliferative anemia and normal iron status, a bone marrow is indicated. Marrow examination can diagnose primary marrow disorders such as myelofibrosis, a red cell maturation defect, or an infiltrative disease (Figs. 58-14, 58-15, and 58-16). The increase or decrease of one cell lineage (myeloid vs.
