Change scrub suits that are visibly soiled or contaminated by blood or other potentially infectious materials. Asepsis and surgical technique Level I: Adhere to principles of asepsis when placing intravascular devices or when dispensing or administering intravenous drugs. Use delayed primary skin closure or allow incisions to heal by secondary intention if the surgical site is contaminated or dirty. Use closed suction drains when drainage is necessary, placing the drain through a separate incision distant from the operative incision. Wash hands before and after dressing changes and any contact with the surgical site. Educate the patient about surgical site infections, relevant symptoms and signs, and the need to report them if noted. Additional studies that are frequently ordered include a urinalysis, urine pregnancy test, and, when indicated, liver function studies. While the list of additional studies could go on and on, the important principle to understand is that few of these studies are helpful when routinely ordered. Selective laboratory evaluation, coupled with a thorough history and physical exam, will prove to be both safer and more cost-effective. Imaging Studies The disease process being treated should dictate the imaging studies ordered. Most patients can be brought to the operating room safely based on the performance of good history and physical exam. Diagnostic imaging studies should be ordered to ﬁne-tune the history and physical and so that appropriate surgical planning decisions can be made. This routine order is somewhat historical, carrying over from the days of prevalent tuber- culosis. Healthy young patients with no evidence of pulmonary disease beneﬁt little from a chest x-ray. It is rare in a patient who has a normal pulmonary exam that the chest x-ray signiﬁcantly alters the operation for which it was ordered. It is more reasonable to obtain a chest x-ray in an elderly patient, and, at times, this results in interesting ﬁndings, such as a lesion requiring further workup. Perioperative Care of the Surgery Patient 17 Informed Consent Informed consent should be viewed as an opportunity for the surgeon to take some time to explain to the patient why an operation is necessary, what the operation entails, what sort of recovery to expect, and what complications might be incurred. The discussion should be frank and honest while sensitive to obvious anxieties of the preoperative patient. It is also helpful, when possible, to have this discussion in the presence of a concerned spouse or family member. With this in mind, the discussion may best be done sometime well in advance of the operation. The discus- sion, when possible, also should include nonoperative therapies for the given disease process. Case Evaluation When considering the approach to the surgical patient as it applies to the case cited at the beginning of this chapter, there are several impor- tant considerations. First, the patient most likely does have a surgical problem and most likely requires an operation. He most likely does not require an emergency operation, and therefore the physicians attend- ing to the patient have some time to fully evaluate the problem with an appropriate series of laboratory tests and diagnostic studies. A thorough and honest assessment of the patient’s comorbid conditions and risks for major surgery is necessary prior to proceeding with a signiﬁcant operation. Summary The successful approach to the surgical patient requires the physician to understand the anatomic and physiologic problems with which the patient presents, listen to the patient, collect a detailed history, and then perform a complete physical exam. Based on the history and physical, a diagnosis, or at least a working differential diagnosis, is derived. Although the aforementioned steps are not unique to surgery, the dif- ference lies in the fact that a surgeon undertakes the aforementioned steps en route to an intervention. The intervention may be minor and expose the patient to minimal risk or it may be very signiﬁcant and may permanently alter the patient’s life. To earn that trust, surgeons must be well trained, exhibit good judgment, understand the limitations of their patients based on their comorbidities, and understand the limitations of their own ability. Development and validation of a multifactorial risk index for predicting postoperative pneumonia after major noncardiac surgery. Report of the American College of Cardiology/American Heart Association Task Force on Practice Guidelines (Committee on Perioperative Cardiovascular Evaluation for Noncardiac Surgery). History of present illness: Three days ago, when lifting a very large pine tree that blew over in a recent windstorm, the patient felt a sudden pain in his left groin. The acute pain resolved, but he continues to feel a “dragging” sensation in same area. Review of systems: Noncontributory: • Gastrointestinal: Denies change in bowel habits; no history of con- stipation; no hematochezia; no nausea and vomiting. Nackman Pertinent social/family history: Non–union worker who loads and unloads delivery trucks. Upon standing, a bulge observed in left inguinal region: no erythema, nontender, easily reduced. The Relevance of Evidence-Based Medicine Many of the issues involved in the care of patients include “age-old” traditions that may be based on empiricism. Until several decades ago, drainage of the gall- bladder bed following cholecystectomy was the standard of care and was based on the belief that drainage of the affected area would promote healing and reduce postoperative complications. Through the 1970s, students and residents heard from their instructors and super- visors: “This is how my mentor taught me to drain the gallbladder bed, so you should do it this way, too. Even though the traditional dogma had been rebuked by demonstrating no need for routine drainage, the clinical practice took decades to change. A signiﬁcant challenge in medicine is to maintain the learning process throughout one’s career, to keep current with the most recent evidence and practice guidelines, to understand the science behind the evidence and the guidelines, and thereby to continue providing optimal patient care. Even seasoned clinicians, when faced with the need to make a complex clinical decision, ask: “What are the practice guidelines for treating patients with this disease? It is important to understand the studies that resulted in the practice guidelines and the implications of these ﬁndings for your speciﬁc patient. Remaining current with important developments and thoughtfully integrating new information into your patient’s care are essential elements of the practice of surgery, whether one is a student, resident, or an experi- enced attending physician. Evidence-based medicine is the purpose- ful integration of the most recent, best evidence into the daily practice of medicine (See Algorithm 2. The practice of evidence-based medicine means integrating individual clinical expertise with the best avail- able clinical evidence from systematic research. Practicing Evidence-Based Surgery 21 Begin Here: Proceed Determine to Next Diagnosis Patient Problem Provide Care of Review Estimate Highest Quality the Prognosis Evidence Determine Decide Harm Best Therapy Algorithm 2. Without clinical expertise, practice risks becoming tyrannized by external evidence, for even excellent external evidence may be inapplicable to or inappropriate for an individual patient.

The living things are both large and small: from worms we can see, to microscopic bacteria, viruses and fungi. The non living things are pollutants in our air, food, dental metal and body products. The good news is that our body can reclaim its sovereignty by throwing the rascals out. With the new electronic insights and technology, our parasitic invaders can be vanquished with the closing of a switch. The tragedies of surgery, organ replacements, radiation, chemotherapies, doses of drugs, even death can be avoided. Killing your invaders is an easy matter: you simply purchase or build the device that can do that and take the proper herbs. Cleaning up dentalware is under your control, too—a financial expense not beyond your reach, hopefully. Trading your body products for unpolluted varieties is a job but not insurmountable. Use your new wisdom and sharp eye to choose a new dwelling as free of pollutants as you can. They allow invaders into the most jealously guarded recess of your being: your genes. You simply need your own genes back on the job, directed by your own body, working for you. Leads To New Discoveries… In every case of the “mysterious” disease diabetes, you find the not-so-mysterious parasite Eurytrema, and the fairly common pollutant wood alcohol. And New Cures… You don’t need dangerous, expensive prescription drugs to get rid of the causes of your illness. Once you know what you are fighting you can pick herbal, electronic, or avoidance methods. And New Hope… Follow the advice in this book preventively, and never worry about your health again! Hulda Regehr Clark began her studies in biology at the University of Saskatchewan, Canada, where she was awarded the Bachelor of Arts, Magna Cum Laude, and the Master of Arts, with High Honors.

In 1979 she left government funded research and began private consulting on a full time basis. Six years later she discovered an electronic technique for scanning the human body. Of course there’s no magic pill or day surgery that will cure a high-pressure job, too little time, too many demands, a bad relationship, or the daily juggling act of kids and career. You can always wait until something serious goes wrong and then a specialist like me might be able to patch you up and send you back out there, but I have a wonderful alternative. I present to you an integrated, novel approach encompassing the best techniques for reducing the stress in your life that I could find, from my experience with both Eastern and Western practices. In essence, this approach employs mindfulness to hold your physical and mental stress and inner-child dialogue to change the paradigm of your thinking which is leading to a painful existence. I recommend this approach to you now as a pre-scription, a life-insurance policy that will go a long way toward keeping you healthy and well and out of my office. While it’s unrealistic to think that you’ll ever be free of stress completely, a sense of freedom and happiness comes from the ability to be fully present during these stressful experiences, without Introduction • 3 amplifying their trauma or identifying with them. When it comes to stressful events, it doesn’t matter what they are, it matters how you are with them. What you put into it, in terms of attempting what I suggest by processing and practicing, will be what you get out of it. Return to reading the rest of the book, in sequence, whenever you’re able to, as each section builds on the one before. This book serves as a practical sequential guide that will bring you to an understanding of how your mind works the way it does and why it does so. There are effective techniques outlined here that will help you to deal with your stress right at the very moment it occurs. There are also approaches that will help you to change the underlying mechanisms at the root of your unhappiness. I’m looking forward to sharing with you what I have found to be personally helpful for both my patients and myself. Hopefully, this will provide you with your own insight into how to live in this world with greater peace and satisfaction. I believe that all of us are connected through our shared humanity and our universal mental suffering. Stress affects every human being on the road of life, but you’re in the driver’s seat now.

In the discovery process opportunities exist discount fluvoxamine generic anxiety symptoms pdf, as illustrated in Chapter 15 discount fluvoxamine 50 mg online anxiety young child, to identify cell-specific enzymes and ligands which may be used to target drugs to these cells 100 mg fluvoxamine with amex anxiety help. The integration of the considerations for drug delivery and targeting into the drug design process may ultimately allow the development of drugs which are not just potent and non-toxic but offer the advantage that their chemical structure dictates the targeting of the drug to its particular site of action through enzyme-based chemical delivery systems using prodrugs. A prodrug is a pharmacacologically inactive compound which undergoes chemical or enzymatic metabolism to the active. Some of the early pharmaceuticals were found to be prodrugs and this finding has led to the subsequent introduction of the metabolite itself into therapy, particularly in cases where the active metabolite is less toxic or has fewer side-effects than the parent prodrug. The administration of the active metabolite may also reduce variability in clinical response between individuals due to differences in pharmacogenetics. Most chemically designed prodrugs consist of two components; the active drug chemically linked to a pharmacologically inert moiety. The prodrug must be sufficiently stable to withstand the pharmaceutical formulation while permitting chemical or enzymatic cleavage at the appropriate time or site. After administration or absorption of the prodrug, the active drug is usually released by either chemical or enzymatic, hydrolytic or reductive processes. Prodrugs are most commonly used to overcome the biological and pharmaceutical barriers which separate the site of administration of the drug from the site of action (Figure 16. Prodrug design has been used to address a wide range of pharmaceutical problems including: • unpalatability • gastric irritation • pain on injection • insolubility • instability. Prodrug design has also been used widely to address pharmacological problems such as poor drug adsorption and drug distribution. As discussed in Chapter 1, prodrugs may be used to enhance the absorption of poorly adsorbed drugs by increasing the lipophilicity of the drug molecule. The modification of a drug to a prodrug may also lead to enhanced efficacy by differential distribution of the prodrug to particular body tissues before the release of the active drug. For example, the administration of the methoxymethyl ester of hetacillin (a 6-side-chain derivative of ampicillin) leads to a more extensive distribution of ampicillin in the body tissues than occurs on administration of ampicillin itself. Conversely, the restriction of tissue distribution which decreases toxic side-effects by restricting the action of a drug to a specific target site in the body may also be achieved through the use of certain prodrug systems as described below. An alternative strategy is to utilize phenotypic differences between cell types to target prodrugs to particular sites within the body through site- specific enzyme-based delivery systems. Improved selective localization of anticancer agents to neoplastic tissue may be achieved using non-toxic prodrugs which release the active drug within the tumor as a result of enhanced enzyme activity in the cell. For example, the prodrug cyclophosphamide is initially activated by hepatic cell enzymes to generate 4- hydroxycyclophosphamide which is then specifically converted to the alkylating cytotoxic phosphoramide mustard in the target cells. As the blood supply to large solid tumors is disorganized, the internal regions are often non-vasculated and the cells, termed hypoxic, deprived of oxygen. The absence of molecular oxygen enhances the reductase activity in hypoxic tissues providing an alternative means of targeting the internal regions of solid tumors using a selective chemical prodrug-delivery system. Certain aromatic, heterocyclic nitro-containing compounds can be reduced in hypoxic environments to produce intermediates which then fragment into alkylating species. For example, the 2-nitro-imidazole compound misonidazole is selectively cytotoxic to cultured hypoxic cells. An alternative approach utilizes the bioactivation of aromatic nitrogen mustards through the reduction of a substituent group in the aryl ring. More recently it has been suggested that bioreductive technologies may have applications in the treatment of other disease states. For example, it has been suggested that the essential role of hypoxia in rheumatoid arthritis offers opportunities to specifically deliver anti-inflammatory agents to arthritic joints using bioreductive prodrugs. This will allow the future development of prodrug-based chemical delivery systems to target specific cell types through the use of the upregulated enzymes in diseased tissues to release the active drug. Furthermore, therapeutic levels of lipophilic prodrugs in the brain can only be maintained if there is an equivalent constant plasma concentration. These problems may be overcome by utilizing a drug delivery system which relies on “trapping” a prodrug in the brain by oxidizing the prodrug to a less membrane permeable derivative. Both phenylethylamine and dopamine have been used to illustrate the principles of this technology and in vivo work has been described in animal studies. The 1,4-dihydro-prodrug is prepared by reduction of a quaternized nicotinic acid derivative of phenylethylamine. On administration the prodrug is delivered directly to the brain, where it is oxidized and trapped as the quaternary ammonium salt. The metabolism and elimination of the drug from the periphery removes excess drug and metabolic products during and after onset of the required action. This overcomes the need to maintain plasma levels which may cause systemic side-effects. The approach has been used most extensively to target drugs to tumor cells by employing an enzyme, not normally present in the extracellular fluid or on cell membranes, conjugated to an antitumor antibody which localizes in the tumor via an antibody-antigen interaction on administration. Following clearance of any unbound antibody conjugate from the systemic circulation, a prodrug, which is specifically activated by the enzyme conjugate, is administered. The bound enzyme-antibody conjugate ensures that the prodrug is only converted to the cytotoxic parent compound at the tumor site thereby reducing systemic toxicity. For example, using cytosine deaminase to generate 5- fluorouracil from the 5-fluorocytosine prodrug at tumor sites increases the delivery to the tumor by 17 fold compared to that achieved on administration of 5-fluorouracil alone. The localized β-lactamase enzyme, which is not normally found in any other tissues, ensures selective release of taxol at the tumor site. The prodrug A is delivered directly to the brain, where it is oxidized and trapped as the prodrug B. The quaternary ammonium salt is slowly cleaved by chemical/enzymatic action with sustained release of the biologically active phenylethylamine C and the facile elimination of the carrier molecule D. Suicide genes encode for nonmammalian enzymes which can be used to convert a prodrug into a cytotoxic agent. Cells which are genetically modified to express such genes essentially commit metabolic suicide on administration of the appropriate prodrug. Typical suicide genes include herpes simplex thymidine kinase and Escherichia coli cytosine deaminase. Although any gene delivery vector may be employed to deliver the gene (see Section 14. These chemical approaches to advanced drug targeting are embryonic and their future development will be dependent on the “fruits” of the genomic and proteomic revolutions. Even though it may ultimately be possible to develop site-specific chemical drug delivery systems for a wide range of therapeutic applications, there will still be a need to address the challenges of chronopharmacology in order to achieve better therapeutic control. Such control requires means of sensing and responding to changes in biological stimuli. This can be achieved by having either a separate biosensor which electronically controls drug release from a drug delivery device or a combination system in which the stimulus has a direct effect on the release of drug from the system. Such a system quantifies electronic signals arising from the interaction between a biosensor and an analyte of interest. Catalytic biosensors use enzymes, microorganisms, or whole cells to catalyze a reaction with the target analyte, while affinity biosensors utilize antibodies, receptors, or nucleic acids to bind with the target analyte. The integration of biosensors with drug delivery systems allows the controlled release of a drug substance in response to the levels of biological modulator.
