Despite overlap 50mg cyclophosphamide with mastercard, this bedside definition of the characteristics of the diarrhea may be helpful to avoid a less productive shotgun approach to the investigation purchase cyclophosphamide 50mg on line. This may be a friendly way to approach the patients problem buy cyclophosphamide 50mg line, and then once a cause of chronic diarrhea is established (such as Crohn disease), then to apply your understanding of physiology to better understand the mechanisms causing diarrhea in that patient with that disorder. Some patients will need higher doses or will need acid-lowering therapy with an H2-receptor antagonist or a proton pump inhibitor to alkalize the fluid in the duodenum and achieve greater activity of the pancreatic enzymes. Bacterial Diarrhea Three major clinical syndromes caused by bacterial infections are 1) food poisoning, 2) infectious gastroenteritis and 3) travelers diarrhea (Table 9). In immunocompetent individuals, enteric infections are usually self-limiting and resolve in less than two weeks. Acute infections diarrheas are classified into toxigenic types, in which an enterotoxin is the pathogenic mechanism, and invasive types, in which the organism penetrates First Principles of Gastroenterology and Hepatology A. Shaffer 211 the enterocyte or colonocyte as primary event (although an enterotoxin may be produced as well). Enterotoxins are either cytotonic (producing intestinal fluid secretion by activation of intracellular enzymes, without damage to the epithelial surface) or cytotoxic (causing injury to the enterocyte as well as inducing fluid secretion). Food Poisoning The food poisoning syndrome characteristically features the development of a brief but explosive diarrheal illness in persons following exposure to a common food such as a restaurant meal or family picnic is suggestive. Food source may be contaminated with bacteria or bacterial toxins; such as Staphylococcus aureus, or Salmonella species. Common causes of acute diarrhea Drugs Bacteria (toxin-mediated, cytotoxic) Viruses Laxatives Clostridium difficile Bacteria (toxin-mediated, cytotoxic) Antacids Staphylococcus aureus Parvovirus (Norwalk agent) Antibiotics Shigella dysenteriae Enterotoxigenic Escherichia coli Reovirus Cholinergic drugs Campylobacter jejuni (rotavirus) Lactose Yersinia enterocolitica (both heat-labile and heatstable Guanethidine toxins) Protozoa Quinidine Vibrio choleraee Cryptosporidia Bacteria (invasive) Vibrio parahaemolyticus Giardia lamblia Digitalis Salmonella Clostridium perfringens Entamoeba histolytica Colchicine Bacillus cereus Enteroinvasive Escherichia coli Parasites Potassium supplements Strongyloides Lactulose Bacteria (unknown mechanism) Trichuris Enteropathogenic Escherichia coli Enteroadherent Escherichia coli Salmonella food poisoning has been attributed to an enterotoxin similar to that of Staphylococcus aureus, but none has been clearly identified. Antibiotic therapy of non-typhoidal Salmonella gastroenteritis fails to alter the rate of clinical recovery. In fact, antibiotic therapy will increase the duration of intestinal carriage of the Salmonella, and is contraindicated. Certain conditions increase the risk of salmonellosis: hemolytic anemia, malignancy, immunosuppression, achlorhydria and ulcerative colitis. In fact, antibiotic therapy increases the duration of intestinal carriage of these organisms. Shaffer 212 o Campylobacter jejuniinduced diarrhea is more common than diarrhea from either Salmonella or Shigella. Campylobacter attaches to the mucosa and releases an enterotoxin that destroys the surrounding epithelia. Clinically, there is often a prodrome of constitutional symptoms along with headache and generalized malaise. A prolonged diarrheal illness follows often with a biphasic character, with initial bloody diarrhea, slight improvement, then increasing severity. The illness usually lasts less than one week, although symptoms can persist for a longer period, and relapses occur in as many as 25% of patients. Staphylococcus aureus produces a heat-stable, odorless and tasteless enterotoxin that is generated in poorly refrigerated desserts and seafoods. Ingestion of the preformed enterotoxin causes nausea, vomiting and profuse diarrhea within 4 to 8 hours. Clostridium perfringens produces a preformed toxin from spores that germinate in contaminated meats cooked at less than 50C. Symptoms are diarrhea and crampy abdominal pain without vomiting, beginning 8 to 24 hours after the meal. The vomiting syndrome is always associated with ingestion of rice and is caused by a preformed toxin that is elaborated when rice is left to cool unrefrigerated. Infectious Gastroenteritis The organisms responsible for bacterial gastroenteritis exert their predominant effects by invading and destroying the intestinal epithelium or by producing various enterotoxins. Treatment is based on restoring fluid and electrolyte balance and maintaining intravascular volume. Even though fluid and electrolyte + transport is impaired, glucose transport is intact. After a 24- to 48-hour incubation period, the disease begins with upper abdominal pain followed by watery diarrhea. Explosive, watery diarrhea is the cardinal manifestation, along with abdominal cramps, nausea and vomiting. After ingestion, Shigella dysenteriae organisms attack the colon, sparing the stomach and small bowel. Shigella organisms adhere to and then, penetrate the mucosal surface, multiply within the epithelial cells, moving laterally through the cytoplasm to adjacent cells by filopodium-like protrusions. Shigella organisms rarely penetrate below the intestinal mucosa, and almost never invade the bloodstream. It has become more readily detected in fecal specimens because of the use of selective growth media and a cold enrichment technique. The spectrum of illness ranges from simple gastroenteritis to invasive ileitis and colitis that must be distinguished from Crohn disease or ulcerative colitis. Enterocolitica causes diarrheal illness in adults, including the elderly, and frequently in children, often less than 5 years of age. Children over 5 years of age develop mesenteric adenitis and associated ileitis, which mimic acute appendicitis. Yersinia is less likely to cause First Principles of Gastroenterology and Hepatology A. If it does, Yersinia is an acute diarrheal episode followed two to three weeks later by joint symptoms and a rash (erythema nodosum). There is no evidence that antibiotics alter the course of the gastrointestinal infection. Ingestion of this organism results in severe crampy abdominal pain and fever, followed within 24 hours by bloody diarrhea that lasts five to seven days. Since the organism is shed in the stool for only a short period of time, early stool collections are critical for the diagnosis.

The func- tional signicance of this ejaculation-subcircuit is still poorly understood but it might well be that these areas play a role in satiety and thus mediate the post- ejaculatory interval buy generic cyclophosphamide 50 mg on line. Truitt and Coolen (13) highlighted the role of the lumbar spinal cord in the processing of ejaculation cheap cyclophosphamide 50mg mastercard. These and other animal studies have clearly shown the existence of a neural circuitry for ejaculation in mammals generic cyclophosphamide 50mg on-line. Positron Emission Tomography-Scan Studies in Humans Although male rat studies are of utmost importance for a better understanding of the neurobiology of ejaculation, brain imaging studies in humans are the tools which provide a better understanding of how the human brain mediates ejacula- tion and orgasm. Brain imaging studies will probably lead to a deeper insight into which parts of the brain mediate ejaculation and which parts are involved in the mechanism of orgasm, how these neural areas are linked to each other, and which parts are disturbed in the different ejaculatory and orgasm disturbances. Eleven healthy male volunteers were brought to ejaculation by manual stimulation of their female partner. Male Ejaculation and Orgasmic Disorders 223 all the activations of these various cortical areas is not yet clear. Further studies need to clarify whether associated sensations of orgasm are mediated by these cortical areas. Unexpectedly, a very strong activation was found in parts of the cerebellum, the meaning of it remaining unclear. Decreased blood ow, and thus less activity was found in the amygdala during sexual arousal, erection, and ejaculation. This may perhaps indicate that the brain looses a state of anxiety or fear during sexual activity. Hypothalamic involvement, as has been demonstrated in animal sexual behavior, has not been found in these male volun- teers. During the last century, prema- ture ejaculation has been considered from both a medical and a psychological view, often resulting in contrasting psychotherapeutic and drug treatment approaches. For a better understanding of the current debate regarding its etiol- ogy and treatment, it is important to consider the history of how clinicians thought about and treated premature ejaculation. History Waldinger (5,15) distinguishes four periods in the approach to and treatment of premature ejaculation. The First Period (18871917): Early Ejaculation In 1887, Gross (16) described the rst case of early ejaculation in medical litera- ture. Although publications were rare, it is worth noting that during the rst 30 years of its existence in the medical literature, early ejaculation was viewed as an abnormal phenomenon but not signicantly as a psychological disturbance. The Second Period (19171950): Neurosis and Psychosomatic Disorder In 1917, Abraham (18) described early ejaculation as ejaculatio praecox and stated that it was a symptom of a neurosis caused by unconscious conicts. On the other hand, some phys- icians stated that premature ejaculation was due to anatomical urological abnormalities, such as a too short foreskin frenulum or changes in the posterior urethra, which had to be treated with incision of the foreskin or electrocautery of the verumontanum. Schapiro described two types of premature ejaculation, type B in which early ejaculation existed from the rst intercourses and type A, which led to erectile dysfunction. Many years later, both types became distinguished as the primary (lifelong) and secondary (acquired) forms of premature ejaculation (20). The Third Period (19501990): Learned Behavior The biological component of premature ejaculation and therefore also drug treat- ment, advocated by Schapiro, was ignored by the majority of sexologists who advocated psychoanalytic treatment. This neglect became even more pronounced after Masters and Johnson (21) claimed the high success rates of behavioral therapy in the form of the squeeze technique, an adaptation of the stopstart tech- nique published by Semans (22) in 1956. Masters and Johnson stated that men with premature ejaculation had learned this rapidity behavior as a result of their rushed initial experiences of sexual intercourse. Prevalence Premature ejaculation is often cited as being the most common male sexual dys- function. Although it has been estimated that as many as 36% of all men in the general population experience premature ejaculation (24), other estimates have been lower. For example, Gebhard and Johnson (25), from a reanalysis of the Kinsey data, determined that 4% of the men interviewed reported ejaculating within 1 min of intromission. The large differences in prevalence numbers are mainly due to the use of various and often totally different denitions of prema- ture ejaculation that have been used. Only by the general use of an empirically dened denition and identical tools to measure the ejaculation time, methodo- logically correct epidemiological studies can provide reliable prevalence data. Evidence-Based Medicine Evidence-based medicine means that the formulation of a seemingly attractive hypothesis of the cause of a disease is not enough for scientic acceptance. There needs to be empirical evidence, preferably replicated in various controlled studies. Male Ejaculation and Orgasmic Disorders 225 For many decades, premature ejaculation was considered to be a psycho- logical disorder that had to be treated with psychotherapy. However, psychologi- cal treatments and underlying theories mostly relied on case reports, series of case report studies, and opinions of some leading psychotherapists and sexo- logists. I believe this to be a typical example of authority- or opinion-based medicine (15). In contrast to authority-based medicine, evidence-based medicine (26) has been accepted today as the hallmark for clinical research and medical practice. In spite of these studies, the belief persists among those involved in sexology that premature ejaculation is a psychological disorder. In order to unravel this dichotomy, it is important to apply principles of evidence-based medicine to both the psychological and neurobiological approaches to premature ejaculation and its treatments. Evidence-Based Research: Psychotherapy The psychoanalytic idea of unconscious conicts being the cause of premature ejaculation has never been investigated in a manner that allowed generalization, as only case reports on psychoanalytic therapy have been published. Masters and Johnson (21) deliberately refuted a denition of premature ejaculation in terms of a mans eja- culation time duration. Instead, they insisted on dening premature ejaculation in terms of the female partner response, for example, as a males inability to inhibit ejaculation long enough for the partner to reach orgasm in 50% of intercourses. It is obvious that their denition is inadequate because it implies that any male partner of females who have difculty in reaching orgasm on 50% of intercourses suffers from premature ejaculation.

Data from this survey indicate that there is much more to do cyclophosphamide 50mg visa, especially in smaller hospitals which face special challenges in implementing the Core Elements cheap 50mg cyclophosphamide with mastercard. Ascension: Building the Infrastructure for Antibiotic Stewardship in a Large Health System Ascension is the largest non-proft health system in the United States purchase 50 mg cyclophosphamide amex, with facilities in 25 states and the District of Columbia, including 141 hospitals and more than 21,000 acute care beds. As a result of these efforts, Ascension has seen reductions in antibiotic use and 15. One 376-bed teaching hospital drove a 70 percent drop in the use of selected antibiotics over a six-month period. Infectious disease physicians and clinical pharmacists tracked and reviewed antibiotic usage in their hospital and gave feedback to providers. State Policies to Improve Antibiotic Use in Hospitals California: California Senate Bills 739 and 1311 require hospitals to develop a process for monitoring antibiotic use and implementing antibiotic stewardship. What can healthcare providers do to support appropriate antibiotic use and prevent infections in hospitals? Too often antibiotics are used inappropriately, putting patients at risk for developing antibiotic-resistant infections, C. With the implementation of antibiotic stewardship programs and resources, patients should expect to receive the right antibiotic, at the right time, with the right dose and duration. Across the United States, the number of antibiotic prescriptions given to children and adults remains high. Numerous studies have found that antibiotics are being prescribed for illnesses which do not require antibiotics, and the incorrect type of antibiotic, dose, or duration are often prescribed across all healthcare settings. In outpatient settings, acute respiratory infections are the leading cause of inappropriate prescribing, while in nursing homes and hospitals, urinary tract infections and pneumonia are the leading conditions for which antibiotic prescribing needs to be improved. Many hospitals have already improved their antibiotic prescribing by following the Core Elements, paving the way for more action and better patient outcomes. When antibiotic stewardship programs and practices are adopted, patients receive the best antibiotic treatment. Helping patients know what they can do to keep themselves and their loved ones safe is part of the discussion of improving antibiotic use. This means raising awareness about the side effects of antibiotics, as well as the unintended consequences of antibiotic use. When everyone plays their part to improve antibiotic use, patient safety is preserved and life- saving antibiotics will be available for generations to come.

That is saving lives but also increasing use neonates and children under five (Kayange et al.

Importantly, the proportion of patients with salmonellosis treated with ciprofloxacin or extended-spectrum cephalosporins markedly increased without an emergence of resistance to either of these antimicrobial agents among human Salmonella isolates. These data suggest there is little correlation between the antimicrobial agents used in persons with Salmonella infections and development of antimicrobial resistance among human Salmonella isolates. Risk assessment 17 If human antimicrobial use is not associated with the increasing antimicrobial resistance seen among Salmonella isolates, what is causing the increasing prevalence of antimicrobial-resistance observed among Salmonella isolates? Possible sources for an increased number of an unusual strain of Salmonella among human isolates may be indicated by the emergence of the same unusual strain among isolates from animals, foods, and other sources. Such investigations often reveal that the source of the increase has been traced to foods of animal origin. For example, beginning in 1969, there was a marked increase in human isolates of Salmonella Agona detected in the United States of America and several other countries (Angulo et al. Salmonella Agona had not been isolated in the United States of America before 1969, but by 1972 it was the eighth most common serotype isolated from humans in the United States of America (Clark, Kaufmann and Gangrosa, 1973). Field investigations and surveillance data determined Peruvian fishmeal fed to chickens was the source of the infections. The identification of Salmonella Agona from Peruvian fishmeal in routine surveillance sampling of fishmeal in 1970 was critical in identifying this new vehicle. The widespread geographical distribution of unusual strains also supports a limited role for person-to-person transmission of Salmonella in the developed world. Data from routine Salmonella surveillance of domestic animals (primarily poultry, pigs and cattle) and foods revealed that 83 percent of all S. Between 1996 and 2001, 8 387 non-typhoidal Salmonella isolates were tested; 522 (6 percent) were S. Recently, a prolonged nosocomial outbreak of infection with fluoroquinolone- resistant S. The index patient had been hospitalized in the Philippines and had probably acquired the infection there (Olsen et al. For animal isolates, the overall incidence of resistance had increased since 1994 but multiple resistance remained rare (Threlfall et al. Again, the most common resistance pattern was to streptomycin, sulfisoxazole and tetracycline, present in 3. This triad was also the most commonly reported resistance pattern among O157 strains isolated from cattle and ground beef collected between 1988 and 1993 (Johnson et al. Resistance to streptomycin, sulfamethoxazole and tetracycline was similar to past surveys. This triad of drugs are rarely used to treat diarrhoea in humans, but sulfa-containing drugs and tetracycline are used in animals. Continued surveillance for antimicrobial resistance in O157strains from human and various animal sources may be useful in identifying reservoirs for this pathogen and practices that encourage development of resistance (Johnson et al. Subtherapeutical doses of tylosin have been commonly used in livestock in Denmark, since, there, 90 percent of Enterococci isolated in pigs are resistant to tylosin. In contrast, in Finland, where tylosin has rarely been used subtherapeutically, only 15 percent of the Enterococci are tylosin resistant. In the Netherlands, avoparcin was used subtherapeutically in pigs and 39 percent of the Enterococci isolated from pigs are avoparcin resistant, as they are to the similar one used in human medicine, vancomycin. In countries that have banned certain subtherapeutic uses of antibiotics, decreases in resistance to those antibiotics have been reported, restoring the effectiveness of those antibiotics for treating disease. For example, in Denmark, after a 1995 ban on the use of avoparcin as a growth promoter, glycopeptide-resistant Enterococci in Danish broiler flocks declined from 82 to 12 percent. Giving antimicrobial agents to chickens and other food animals selects for antimicrobial resistance among bacteria (e. Gentamicin and vancomycin are important antimicrobial agents for the treatment of human enterococcal infections. This highlights concern that the food supply can provide the seeds of antimicrobial- resistant Enterococci, which may be carried in the intestinal flora of the general population. Once introduced into a medical facility, they may blossom to clinical importance under the increased selective pressures of antimicrobial use in humans. Gentamicin resistance among Enterococci isolated from meat purchased from grocery stores and from outpatient human stools were studied in the United States of America during the period 19982001 (Kretsinger et al. Bacitracin is widely used as a topical or ophthalmic antibiotic ointment for wounds. It is used in some hospitals as the primary antibiotic barrier for patients with severe burns.
