    Title Teaching Radical Prostatectomy in Sub-saharan Africa.
    Date April 2008
    Journal The Canadian Journal of Urology

    In the United States alone, approximately 220,000 new cases of prostate cancer will be detected in 2007, and 27000 men will die of that disease. African American men will suffer disproportionately, having a prostate cancer incidence that is nearly 60% higher than their Caucasian counterparts. In fact, it is widely accepted that African American men have the highest incidence of prostate cancer in the world. This observation has led investigators to study the prostate cancer risk among African men in an effort to identify factors responsible for the high incidence of prostate cancer that plagues the African American population. Findings suggest that the public health burden of prostate cancer to native African men is substantial. Effective management of prostate cancer depends on early detection of the disease and its definitive treatment. Cost-effective management can be elusive. Radical prostatectomy can cure clinically localized disease and may offer long-term cancer control in patients with stage T3 disease. Of the various forms of radical prostatectomy, radical perineal prostatectomy is ideally suited to accomplish these goals in sub-Saharan Africa. A program to teach radical perineal prostatectomy has begun in Dakar, Senegal. It is a system based on graded surgical responsibility. High-quality audiovisual guides familiarize surgeons with the procedure's unique anatomic concerns. They then observe live procedures, assist in live procedures and eventually begin performing the live procedures under direct supervision. Repeated performance of the operation with simultaneous critique is the hallmark of this program, the goal of which is to establish a center of excellence where surgeons throughout the continent can come to learn this technique.

    Title Fluorescence Identifies an Alkaline Cell in Turtle Urinary Bladder.
    Date February 1986
    Journal The American Journal of Physiology

    Intracellular pH (pHi) of turtle bladder mucosal cells was studied by the trapped fluorescent indicator technique. Bladders efficiently accumulated and converted 4-methylumbelliferyl acetate to its pH-sensitive derivative 4-methylumbelliferone (4MU). Excited at the pH-indifferent wavelength 334 nm, bladders fluoresced a uniform blue. Using pH-sensitive 365-nm excitation, 10-20% of the mucosal cells fluoresced distinctly brighter, suggesting a more alkaline pHi. Using the 365/334 ratio to quantitate pHi, this difference averaged 0.1 pH units. Bright cells were more distinct after SITS or acetazolamide but disappeared after digitonin permeabilization, dinitrophenol, or treatment with propionate, DMO, and NH4Cl. Essentially the same population of bright cells was identified by carboxyfluorescein diacetate. The brighter cell corresponded exactly to a population of cells with distinctive acridine orange staining and bright costaining with the potential-sensing probes Di-O-C5, Di-S-C3, and 4-Di-5-Asp. Two extremes of bright cell shape were seen: an elongate cell, prevalent under conditions stimulating H+ secretion, and a more compact cell, when acidification was inhibited. These observations support the hypothesis that acidification represents H+ secretion via the luminal membrane and that a primary role of carbonic anhydrase in this process is to support the exit of base from the cell. The more alkaline cells appear to be the carbonic anhydrase-rich cells. These cells are chemically isolated from the surrounding granular cells and change their morphology in response to changes in acidification. These special properties indicate a unique role for the carbonic anhydrase cell in H+ secretion.
