Prostate Cancer Unmasked


Book Description

The FDA approved the PSA test in 1986 as a "monitor for treatment response and disease recurrence". Later in 1994 the FDA approved the PSA test as a screening tool for prostate cancer. But the question remained: what was the best treatment tool? I am reviewing 9 different treatment approaches in this book. They are all currently in use by different physicians. But they do not necessarily serve the patient best. Brachytherapy does not quite do it. It improves the cancer for a period of time, and after a few years it returns with a vengeance. The radical prostatectomy and the robotic prostatectomy have helped a significant amount of patients. But long-term studies show that there can be a recurrence rate of as much as 25 to 30%. In addition there are significant side effects like a killed sex life and involuntary dribbling of urine, if the bladder outlet was injured during the surgery. Quite often urologists recommend "active surveillance". This approach to prostate cancer means that a 71 to 75 year old prostate cancer sufferer is kept in suspense by the urologist. An initial rectal biopsy is done with a histology assessment where a Gleason score is analyzed. If this score is 6 or less, the cancer is presumed to be less aggressive and active surveillance is done. Another biopsy is done 1 year later and this could go on until the patient dies of a heart attack or a stroke. I think that prostate cancer should be treated early before metastases develop and the cancer gets out of control. There are other methods that actually can get rid of the prostate cancer, for instance cryoablation therapy following a mapping biopsy. In this latter method 60 biopsies are placed like a grid through the entire prostate gland to identify the exact location where prostate cancer has developed. This is done through the perineum (between the scrotum and the anal opening). Prostate cancer can often be multifocal: there may be two or three areas where prostate cancer is located. One month after the mapping procedure probes are introduced in the same way, through the perineum and the identified cancer lesions are treated with cryotherapy twice. I am explaining this in chapter 15 in more detail. According to Dr. Onik, an interventional radiologist in Ft. Lauderdale, active surveillance is something that should be abandoned. Instead the following treatment approach should be adopted. 1. A rising PSA or single PSA above 30 should trigger a referral for a mapping biopsy through the perineal approach under a general anesthetic. The treating physician can sterilize the area and perform biopsies in a sterile fashion, which prevents infection. This is a huge advantage above the standard transrectal approach, which can lead to infections like prostatitis and blood poisoning. 2. Based on the result of the mapping biopsy targeted ablation cryotherapy is performed one month later eradicating all the cancer foci determined through the mapping biopsy. 3. Follow-up PSA levels are obtained every three months for 2 years. If the PSA is less than 3.0, the patient is considered cured. If there is a rising PSA level point 1 and 2 above are repeated until a cure is achieved. Dr. Gary Onik published a 10-year follow-up study that had a 100% survival rate and a 94% cure rate in 70 men with prostate cancer. The reason for such good results is that attention is paid to detail, to the exact location of the cancer and that all cancer is completely eradicated. In my opinion this is the new blueprint of a common sense approach to prostate cancer. Read more details about this in chapter 15. Apart from the above mentioned treatment methods I reviewed external beam radiotherapy, laser ablation therapy and high-intensity focused ultrasound treatment. I noticed that the long-term cure rates over 10 years differ considerably from one treatment modality to the next. All of this is reviewed in detail in this book.

When Political Transitions Work


Book Description

The peaceful end of apartheid in South Africa was a monumental event in late twentieth century history. A racist regime built upon a foundation of colonialist exploitation, South Africa had become by that point a tinderbox: suffused with day-to-day violence and political extremism on all sides. Yet two decades later it was a stable democracy with a growing economy. How did such a deeply divided, conflicted society manage this remarkable transition? In When Political Transitions Work, Fanie du Toit, who has been a participant and close observer in post-conflict developments throughout Africa for decades, offers a new theory for why South Africa's reconciliation worked and why its lessons remain relevant for other nations emerging from civil conflicts. He uses reconciliation as a framework for political transition and seeks to answer three key questions: how do the reconciliation processes begin; how can political transitions result in inclusive and fair institutional change; and to what extent does reconciliation change the way a society functions? Looking at South Africa, one of reconciliation's most celebrated cases, du Toit shows that the key ingredient to successful reconciliations is acknowledging the centrality of relationships. He further develops his own theoretical approach to reconciliation-as-interdependence-the idea that reconciliation is the result of an integrated process of courageous leadership, fair and inclusive institutions, and social change built toward a mutual goal of prosperity. As du Toit conveys, the motivation for reconciliation is the long-term well-being of one's own community, as well as that of enemy groups. Without ensuring the conditions in which one's enemy can flourish, one's own community is unlikely to prosper sustainably.

Male Hypogonadism


Book Description

Recent advances in cellular and molecular biology have markedly increased our understanding of normal and abnormal hypothalamic–pituitary–testicular function. Like other volumes in the Contemporary Endocrinology series, the goal of Male Hy- gonadism: Basic, Clinical, and Therapeutic Principles is to link current knowledge of basic biology to the practice of medicine. The development of new methods for testost- one replacement has substantially increased the number of men who are seeking to determine whether they are hypogonadal, and who are using testosterone replacement therapy, thus mandating a broader understanding of testosterone deficiency. The chapters of this book were contributed by authors from around the world, and from various scientific and clinical disciplines, who have devoted their careers to the study of the physiology and pathophysiology of the male. Thus, this comprehensive and focused volume is intended for a wide audience encompassing both basic scientists and practicing clinicians. Its scope will provide a wealth of information for students and fellows as well.




Covid-19 Unmasked: The News, The Science, And Common Sense


Book Description

How can we keep up with the deluge of information about COVID-19 and tell which parts are most important and trustworthy?We read: 'Scientists recommend', 'Experts warn', 'A new model predicts'. How do scientific experts come up with their recommendations? What do their predictions really mean for us, for our friends, and our families?How can we make rational decisions? And how can we have sensible conversations about the pandemic when we disagree?These are the questions that this book is trying to address.It is written in the form of dialogues. Alice, a student of epidemiology, explains the science to three of her fellow students who have a lot of questions for her. The students have the same concerns that we all share to varying degrees: What the pandemic is doing to our health, our economy, and our cherished freedoms. In their conversations, they discover how the science relates to these questions.The book focuses on epidemiology, the science of how infections spread and how the spread can be mitigated. The science of how many infections can be prevented by certain kinds of actions. This is what we need to understand if we want to act wisely, as individuals and as a society.The author's goal is to help the reader think about the COVID-19 pandemic like an epidemiologist. About the various preventive measures, what they are trying to accomplish, what the obstacles are. About what is likely to be most effective in the long run at moderate economic and personal cost. About the likely consequences of personal decisions. About how to best protect oneself and others while allowing all of us to lead lives that are as close as possible to normal.While some chapters present slightly more advanced material than others, no scientific background is needed to follow the conversations. The technical concepts are explained in small steps and the occasional calculations in the book require only high-school mathematics.Related Link(s)

Cancer Chemoprevention


Book Description

Despite significant advances in cancer treatment and measures of neoplastic progression, drug effect (or early detection, overall cancer incidence has increased, pharmacodynamic markers), and markers that measure cancer-associated morbidity is considerable, and overall prognosis as well as predict responses to specific therapy. cancer survival has remained relatively flat over the past All these biomarkers have the potential to greatly augment several decades (1,2). However, new technology the development of successful chemoprevention therapies, allowing exploration of signal transduction pathways, but two specific types of biomarkers will have the most identification of cancer-associated genes, and imaging of immediate impact on successful chemopreventive drug tissue architecture and molecular and cellular function is development—those that measure the risk of developing increasing our understanding of carcinogenesis and cancer invasive life-threatening disease, and those whose mo- progression. This knowledge is moving the focus of cancer lation can “reasonably predict” clinical benefit and, therapeutics, including cancer preventive treatments, to therefore, serve as surrogate endpoints for later-occurring drugs that take advantage of cellular control mechanisms clinical disease. Thus far, the biomarker that best measures to selectively suppress cancer progression. these two phenomena is intraepithelial neoplasia (IEN) Carcinogenesis is now visualized as a multifocal, because it is a near obligate precursor to cancer.
