In our country with more than double the number of physicians required for our population, it becomes obvious why such a problem exists. In this regard, our International Scientifc Organizations should help by writing in large print on Membership certifcates, that this is not a Specialty Title. More important yet, our patients need to be trained (by allergists too) to recognize alternative witchcraft from some modes of alternative medicine that appear to help some patients with mild allergic problems, associated with an overload of undue stress. Mild cases excluded, long term control and management rests with specialists as well. There are no organized courses on allergy diagnosis and treatment during General Practitioner specialization. Efforts required for improved patient care are underway to introduce diploma courses in allergy at some centers.

In recent years there has been greater awareness and recognition of the importance of the specialty of allergy. Additionally, Japanese Society of Allergology and Japanese Medical Association conduct training workshops and seminars to educate the general practitioners. Enhancements required for improved More standardized allergens need to be made available in Japan. There is no consensus on the diagnosis of drug allergy, and a preventive strategy for drug allergy is needed. Education on allergic diseases at school for children and their parents are needed, especially to treat food allergy and anaphylaxis appropriately. Insurance coverage for allergic diseases is insuffcient and this needs to be addressed. Most certifed allergists practice in urban areas, so there is a need for better allergy services in rural areas. For 13-14yrs old (wheeze ever, current wheeze (within the last 12 months), and physician diagnosis of asthma are 25.

More epidemiological studies are needed to ascertain the extent of the allergic disease burden. We need more allergists working in country areas, because the majority of allergists are working in Riga, the capital of Latvia. Currently, the Credentialing Committee of the immunology National Specialist Register, Academy of Medicine Malaysia, has taken up the matter and initiatives are underway to form the Clinical Immunology Credentialling Subcommittee (which will include Allergy) and create a training program for paediatricians and physicians. Enhancements required for improved Patient care would be enhanced by the recognition of clinical immunology and allergy as a medical (internal patient care medicine and paediatrics) sub-speciality. Better training in allergy is required at the undergraduate level and for General Practitioners. The creation of specialist centers, and epidemiological studies to assess the socio-economic burden of allergic diseases, are needed. More education is required, targeted appropriately for specialists, pediatricians, general practitioners, allied health workers and patients. Allergists work immunology service provision between in the third level hospitals and private allergy and asthma clinics in cities. Promote the need for health insurance system to cover the costs of allergic disease, including immunotherapy. Rural immunology service provision between areas are neighboring urban areas where allergy services are provided, and most patients would have to urban and rural areas travel less than 150 miles for an allergy service. Enhancements required for improved We need to include allergy teaching in medical university programs and to recognize allergy as a specialty.

There are great geographical differences in the availability of immunotherapy provision between urban and rural areas services, and this is more seldom offered in rural areas. Enhancements required for improved the lack of a formalization of allergology may be the reason for the fragmented education about allergic patient care diseases, for both undergraduate medical students and specialists in Norway. The competence should be linked to service at an allergy center for 1-2 years, and a structured education in allergology. General practitioner training in allergy Though we hold continuous medical education lectures sponsored by the pharmaceutical industry, and we diagnosis and treatment hold a National congress every 2-3 years, there is a lack of knowledge within our general practitioners. We have made history by starting the frst allergy and clinical immunology trainingprogram in Panama in 2010. We have have a plan to gradually grow the specialty and society for the better management of allergies in our country. However, in recent years through several diagnosis and treatment courses we are trying to change this situation. However, there is a large patient care defcit in the training of doctors in immunlogy and allergy. Sensitization to common aeroallergens in children with allergic respiratory diseases at a tertiary hospital. In 1972, these allergists formed the Philippine Society of Allergology and Immunology, thus formalizing the existence of the distinct subspecialty in the country. General practitioner training in allergy Allergy and Immunology is part of the medical curriculum, both in Internal Medicine and Pediatrics in all diagnosis and treatment medical schools. This would be facilitated by arranging for new allergists to spend patient care time studying in centers abroad, and by easier, affordable access for clinicians to information and education about allergy. Epidemiological studies are required to assess prevalence of allergic diseases on a regular basis. Research grants are needed to support the implementation of management guidelines for allergic diseases.

There are no allergy practicing nationally subspecialty fellowships, and most allergists have done their subspecialty training in overseas institutions. Many physicians with little allergy specialist training practice allergy, eg, dermatologists, otolaryngologists. General practitioner training in allergy the conditions are very common, and general practitioners manage them at primary level and refer the diagnosis and treatment problem cases. Allergy practice in patient care institutions is carried out by specialists and academics, although the bulk of care is conducted at the primary care level. The greatest challenge is the small critical mass of specialists due to the small population. This is based pollutants that are implicated in the on an environmental impact study. The Allergy Society of South Africa also conducts diagnosis and treatment congresses and workshops for General Practitioners. We also have an urgent need for epidemiological studies to assess the economic impact of allergic disease. Association between sensitization to outdoor spider mites and clinical manifestations of asthma and rhinitis in the general population of adults. Neither General Practitioners nor Pediatricians receive specifc training about the diagnosis and treatment of allergic diseases during their education. If General Practitioners have a special interest they usually attend an allergy department for one month during postgraduate training. Some regions have allergy urban and rural areas services only in Private Hospitals but not in Public Hospitals. Proceedings of 4th Scientifc Sessions, Allergy and Immunology Society of Sri Lanka.

General practitioner training in allergy General practitioners do receive training in allergy diagnosis and treatment but the level of knowledge is not diagnosis and treatment at the desired level. This training is received during medical school at the level of undergraduate training. The creation of specialist centers with good communications between these centers and primary care (the hub and spoke model) would greatly enhance patient care.

The purpose of this study was to re-evaluate the sexually transmitted infection worldwide. A single 2 g dose of oral metronidazole examine treatment diferences by bacterial vaginosis status. A meta-analysis of six published studies metronidazole is superior to single-dose metronidazole for found that multiple doses of metronidazole resulted in fewer the treatment of trichomoniasis in women, irrespective of treatment failures than single-dose treatment. We found that women receiving the 7-day-dose and willingness to be randomly assigned to either of the metronidazole treatment were half as likely to be T vaginalisstudy groups. A secondary aim was to examine to be randomised, and inability or unwillingness to return treatment diferences by bacterial vaginosis status. An openindependent Data Safety and Monitoring Board monitored label design was used to simulate real-world conditions the data every 6 months, with a priori stopping rules. Because of the this assay was allowed for investigational use only, and sensitive nature of the surveys both at enrolment and was performed by use of the direct tube sampling system. After eligibility screening and written informed consent, the cultures were considered T vaginalis-positive if any the participants were asked to take a survey, provide live trichomonads were detected, and T vaginalis-negative urine for pregnancy testing, and self-collect vaginal after three negative pouch readings.

The proportion of patients with follow-up these events did not difer signifcantly by study group. Amsel criteria37 had been used been favoured over 7-day-dose treatment, because to test for bacterial vaginosis at the clinics. Symptoms for adherence to treatment is not an issue, especially if the bacterial vaginosis and trichomoniasis are often similar,7 patient is under direct observation by a clinician. Indeed, in this study selfmetronidazole for trichomoniasis, providing further reported adherence was higher among patients receiving rationale for recommending 7-day-dose metronidazole as the single dose compared with patients receiving the frst-line treatment for trichomoniasis. The majority trichomoniasis should be upheld even for those women of women who enrolled were African American. More studies of women with asymptomatic7 tested for T vaginalis with culture, we found a reduced trichomoniasis are needed. The diference We chose to use an open-label study design to factor in between groups might be due to chance, and reviews43,44 real use conditions, although masking participants to have found that multiple doses of metronidazole are safe treatment is often preferred. Strengths of the study were that study design, treatment duration and follow-up times randomisation appeared to work well, as baseline were diferent for each treatment group, which could characteristics were similar by group (table 1), loss to have resulted in diferences in sexual exposure. Moreover, the reported sexual behaviour might not be accurate, we intention-to-treat, modifed intention-to-treat, and other used computer-assisted interviews, which have been sensitivity analyses were consistent with each other.

On one side are academicians, pharmaceutical companies, and government agencies, who claim the disease is usually mild and virtually always easily cured. On the other side are chronic Lyme disease patients and their doctors, who say that infection may survive the standard four weeks of antibiotic treatment, and that its impact may be debilitating and difficult to treat. This report adds another dimension to the debate by focusing on Lyme disease as a business model. An examination of patents, marketing agreements, and revenue streams reveals the potential for the appearance of conflict of interest for many of the individuals setting Lyme disease policy. These policies, created in part to enable the analysis of data required for product approval, have also served to disenfranchise large numbers of infected patients no longer meeting the official standard for diagnosis with the disease. Untreated by physicians and uncovered by insurance companies, these patients have become increasingly ill. In the pages that follow we will detail the straightforward path of revenue and its relationship to multinational pharmaceutical companies, venture-backed biotechnology firms, government agencies, and academicians. As long as the status quo is allowed to stand, large numbers of people exposed to this rapidly emerging infection will continue to go undiagnosed and untreated for Lyme disease, and will be placed at severe risk for lifelong health problems, including arthritis, neurological impairment, psychiatric illness, cardiac illness, gastrointestinal disease, and more. It is most commonly transmitted to humans through the bite of an infected Ixodes scapularis or Ixodes pacificus tick in its ecosystem of choice-the shaded, woody areas of the suburban United States. Though most people still associate Lyme with the single infection caused by the Bb spirochete, recent studies show it can be far more complex. Ticks that carry Borrelia burgdorferi may also carry co-infections such as Ehrlichia and Babesia, leading to a broader definition of Lyme disease in recent years. This creates a dynamic situation with many opportunities for exposure for each individual. But throughout the rest of the state, we see many more cases in other counties, such as Fairfield County, Litchfield County, and New Haven County. In a study done by Matthew Carter and associates at the Connecticut Department of Health, you can see that through an active surveillance, they identified about 1,000 cases among 400 physicians who maintain an active Lyme disease surveillance. With almost 11,000 practicing physicians in Connecticut, the number of cases reported was only about 10 percent of the expected reporting. Atypical forms of this rash, taking on a large variety of forms, are seen far more commonly. The rash can be very small or very large (up to twelve inches across), and can imitate such skin problems as hives, eczema, sunburn, poison ivy, fleabites, and so on. But most practitioners, even those in endemic areas, simply are unaware of the complexity and diverse presentation. The Great Imitator When, due to these diagnostic errors, patients are treated insufficiently or not at all, they become extremely ill. Since the Lyme spirochete can infect virtually any organ in the body, it can mimic many other diseases. Professionals also agree that Lyme disease patients who have gone undiagnosed and now suffer later stage disease may continue to experience debilitating symptoms following a month-long course of antibiotics. All agree that these symptoms-arthritic, neurological, and multisystemic-can last for months, years, or throughout life. While some contend Lyme is underdiagnosed and others that it is overdiagnosed, most recognized authorities believe that initial diagnosis of Lyme disease can be based on blood tests alone. Common Misconceptions on the Part of Physicians Even in the face of this consensus, misunderstandings abound. The First Scientific Controversy: Persistence of Infection Much of the medical mainstream, including the Yale-based physicians who originally studied Lyme disease, contend most cases can be successfully treated with 30 to 60 days of antibiotics, which they contend kills the Lyme spirochete. If symptoms continue, say these physicians, they are probably caused by something other than the Lyme bacteria. Alternatively, they suggest, illnesses unresponsive to a month or two of antibiotic treatment are caused by an unrelated problem, like chronic fatigue syndrome, psychiatric illness, lupus, multiple sclerosis, or fibromyalgia. Moreover, these same physicians question long regimenrs of expensive antibiotics, labeling them as unnecessary and sometimes dangerous. The very sickest patients, who almost universally continue to decline under such treatment protocols, have found their way to a group of clinicians and researchers whose studies and experience stand in powerful opposition to the findings and opinions at Yale. These doctors, including such experts as psychiatrist Brian Fallon of Columbia Presbyterian and Dr. Willy Burgdorfer, the National Institutes of Health scientist who discovered the Lyme spirochete, Borrelia burgdorferi, say that an audit of the peerreviewed literature reveals no evidence that infection cannot survive the standard 4 weeks of antibiotic treatment. Instead, these clinicians and researchers contend, patients with continuing symptoms are usually ill because the Borrelia burgdorferi spirochete has never been eradicated from the body. W hile the results are not yet in, it may be that all such studies are problematic to one degree or another based on the range of co-infections, known and unknown, and hundreds of borrelia sub-strains, each responding differently to the variety of antibiotics in the arsenal available today. Indeed, While double-blind studies of simple antibiotic protocols have been inconclusive, dozens of peer reviewed studies in microbiology and cell biology journals nonetheless indicate that active, ongoing spirochetal infection is the cause of the persistent symptoms in chronic Lyme disease. To determine this, they studied 63 patients with erythema migrans, the signature skin lesion of Lyme disease, removing the active edge of the rash for biopsy and examining growth in test tube cultures. Preac-Mursic of the University of Munich in Germany cultivated Borrelia burgdorferi from biopsies of the iris and skin as well as samples of cerebrospinal fluid after antibiotic therapy for Lyme borreliosis. Although the patients in this study, by and large, tested negative by Western blot-although they lacked diagnostic antibody titersfihey still had subclinical or clinical disease. Those same spirochetes, grown in fibroblasts cultured in a test tube and then treated with antibiotics, survived as well. Cornell University scientist Rheinhard Staubinger, for instance, infected 16 dogs with Borrelia burgdorferi by tick bite. Four months (120 days) after tick exposure, 12 dogs were treated with antibiotics for 30 days while 4 control dogs were not treated at all. In experiments performed both in vivo and in vitro and presented in the peer-reviewed literature, it has been shown that different strains respond differently or not at all to the host of antibiotics used to treat Lyme disease. Although some medications may be useful for treating Borrelia burgdorferi alone, they may be ineffective against the co-infections. For instance, amoxycillin will be ineffective against Ehrlichia (which requires doxycycline or another antibiotic in the tetracycline family) as well as Babesia (often treated with Mepron. Given these facts, say the clinicians, it is easy to see why a month of low-dose doxycycline or amoxycillin might fail to do the trick when tick-borne disease has been undiagnosed and untreated in an individual for years. According to one theory still under investigation, Bb spirochetes under environmental stress lose their cell walls, becoming resistant to conventional antibiotics. One line of research suggests that when under pressure from its environment, the Lyme disease spirochete loses its cell wall. In doing so, it becomes resistant to the majority of antibiotics, which are engineered to work by attaching to bacterial cell walls. When a given environmental stressor including antibiotic therapyis halted, the spirochetes may come out of hiding and revert to conventional, cell-walled forms. Clinicians say they can treat the cell-wall-deficient forms of the Lyme disease spirochete with Flagyl, an antibiotic that causes them to convert to cell-wall forms, which are vulnerable to conventional antibiotics. Borrelia burgdorferi is undergoing a period of rapid evolution, according to molecular biologists at the University of Utah Medical School, the London School of Hygiene and Tropical Medicine, and the Institute for Genomic Research in Rockville, Maryland. These observations lead one to the conclusion that certain subsets of patients with Lyme disease may require prolonged antibiotic treatment and that presently available chemotherapeutic modalities may be suppressing but not eradicating the infection. If a doctor sees Lyme disease as underdiagnosed and thus treats all comers, the actual diagnosis might remain unrecognized and untreated while unnecessary use of antibiotics might lead to antibiotic-resistant infections in the human blood reservoir at large. On the other hand, if a doctor sees Lyme disease as overdiagnosed and thus hesitates to treat, patients will go on to develop late stage, disseminated Lyme disease. By the time such individuals are finally diagnosed, they are often simply too sick to respond to a single month of antibiotics. The overdiagnosis-underdiagnosis debate and the issue of chronicity are key to the quagmire of Lyme disease politics and the conflicts of interest that result. The reason is this: Redefinition in these areas was a prerequisite for launch of Lyme disease products, including vaccines and diagnostic tests. Eugene Shapiro, Steere proved the Connecticut syndrome-named for its epicenter in the town of Lyme-was caused by the bite of an Ixodes tick. Years later, government scientist Willie Burgdorfer of the Rocky Mountain Laboratories discovered that the tick transmitted Lyme disease through a spirochetal bacterium, Borrelia burgdorferi, named after its discoverer. Lyme Disease and Diagnosis But though the critical microbe had been found, the effort to diagnose Lyme remained a challenge, in large part due to the absence of a gold standard laboratory test-one that could culture Bb spirochetes from the blood. These bound antibodies can then be detected when a second solution, which contains antibodies to human antibodies, is added to the preparation. Linked to these second antibodies is an enzyme, which changes color when a certain chemical is added to the mix. To distinguish the false positives from the true positives, the Western blot (also known as an immunoblot) is used. In this test, the laboratory looks for antibodies directed against a wide range of Bb proteins. This is done by first disrupting Bb cells with an electrical current and then "blotting" the separated proteins onto nitrocellulose, nylon, or other synthetic membranes. The current causes the proteins to separate according to their mass, measured in kilodaltons (kDa). If the patient has antibodies to a specific Bb protein, a "band" will form at a specific place on the immunoblot. A layer of complexity is added to analysis because the Western blot report usually contains two parts: IgM and IgG. These are immunoglobulins (antibody proteins) produced by the immune system to fight infection. IgM is produced fairly early in the course of an infection, while IgG response comes later. The IgG response, according to the traditional model, tends to start several weeks after infection and peak months or even years later. Similarly, IgG response can remain strong or decline with time, again regardless of treatment. Assuming normal amounts of variation found in nature, it is a given that unusual banding patterns will occur. Raising the Bar Back in what now seems like the prehistory of Lyme disease testing, the year 1991, these unavoidable variables were magnified by a system mired in chaos. There was, at the time, no agreed-upon standard for what constituted a positive Western blot. Different laboratories used different antigen preparations made from different strains of the Bb spirochete to run the test. Some required a certain number of bands to constitute a positive result, while others required more bands or less. In a study published in February of that year with Frank Dressler and colleagues from Germany, he performed immunoblots on several dozen patients with well-characterized Lyme disease and a strong antibody response. By looking at the resulting blot patterns and doing some fairly involved statistical analysis, the team determined which bands showed up most often and which best distinguished Lyme disease patients from control subjects who did not have Lyme disease. They found that by requiring 2 of the 8 most common IgM bands in early disease and 5 of the 10 most common IgG bands after the first weeks of infection, they could make the results the most specific, in their view, without sacrificing too much sensitivity. This flew in the face of a general consensus that different bands on a Western blot have different relative importance. But these bands correspond to common proteins in many bacteria, not just Borrelia burgdorferi, and so are of limited diagnostic usefulness, especially in the absence of other, more species-specific bands. But it is also the most commonly appearing band in control subjects, probably because people are exposed to a variety of spirochetes throughout life and so their sera might cross-react with this protein. As a rheumatologist, it was only natural that his patients present with a frank arthritis of Lyme, often with a swollen joint. But the study did not include patients from other disciplines, including those who might show up at the office of a gastroenterologist, neurologist, or opthalmologist. Even more puzzling was the omission from consideration of bands at 31 and 34 kDa, corresponding to OspA and OspB, among the most species-specific proteins of the organism. Often absent in early disease, Osps A and B tended to come into prominence as patients become increasingly ill. Prior to referral, 409 of the 788 patients had been treated with antibiotic therapy. The most common reason for lack of response to antibiotic therapy was misdiagnosis. If so, it would mean he had developed a test far beyond the state of the art for 1993, not to mention today. It is difficult to accept uncritically his claim that the antibody testing protocols he uses are so far and away superior to any other without the same independent testing other labs are subjected to . The reasoning is circular: the presumption is that his tests are superior because they render the highest correlation between seropositivity and actual Lyme disease, but the definition of "actual Lyme disease" in the study is derived almost exclusively from the test results generated at his lab. Although false negative serologies are widely recognized as common in early Lyme disease, it is often claimed that they are extremely rare phenomena later in the course of the illness. This approach systematically excludes all patients from areas that have not been investigated for B. Response to treatment required for diagnosis: Of the patients thought to have active Lyme disease, at least 52 had already been antibiotically treated before evaluation by the authors.

Considering these cost savings may make such programmes even cheaper and mean that population H. Other limitations of the current health economic literature are that less than half of studies conduct a probabilistic analysis to evaluate the uncertainty in the data modelled, and even fewer present the data in a way that is meaningful to health-care decision-makers. This type of analysis is needed for other populations using other assumptions relevant to local populations. Although this is a valid approach, it could be argued that societal costs are more important for a 117 national screening programme. Finally, it is important to emphasize that nearly all models reported benefit in terms of life-years saved. This will overestimate the benefit of the programme as most of the life-years saved will be in the elderly, many of whom have other comorbidities that may limit their quality of life. Future economic models should use current systematic review data on the efficacy of H. Uncertainty in the data should be evaluated using probabilistic analyses, and there is no model currently published that fulfils all these criteria.

Search strategy for economics of Helicobacter pylori test and treat to prevent gastric cancer 1. Gastric cancer is also the third leading cause of cancer death in both sexes worldwide, with an estimated 723 000 deaths in 2012. Gastric cancer is one of the leading cancers in many areas of Latin America, particularly in Central America and in the Andean countries. An improved understanding of the natural history of the infection will enable the development of tests for an early diagnosis, or even better, the identification of patients at risk of developing gastric cancer. Most of these factors interact with receptors in gastric epithelial cells to signal different cellular pathways that eventually lead to changes in the expression of genes involved in inflammation, cellular proliferation, invasion, and metastasis. Decades of gastric inflammation may also induce epigenetic changes, such as methylation of genes, that would also lead to carcinogenesis. Considerations All the bacterial or cellular factors described above represent potential biomarkers for risk, early diagnosis, or prognosis for gastric cancer, but there are important considerations in the selection of candidates. The utility of biomarker tests is optimized when they are applied in the right context. Gastric cancer is a multifactorial disease, and a proper combination of markers, including host genetic factors 122. In fact, very few cancer biomarkers already in clinical use have high sensitivity and specificity, and for many of them, whether they really improve cancer outcome is currently questioned. It is in these countries where identification of patients at risk and early disease detection are most needed, but it is also in these countries where resources for health are limited. Regional gastric cancer mortality rates the regional gastric cancer mortality rate is a geographical marker for populations at risk and an important criterion in the selection of populations at greater need of targeted intervention programmes. Most studies to date on the utility of the pepsinogen test have been performed in Asian countries, where evidence shows that it is a useful serological test to identify patients with gastric atrophy. In cardia gastric cancer cases with low PgI levels, the risk increased to an odds ratio of 11. Few studies have been performed in Latin America, and most of them with a small sample size. The study also suggested that serology for CagA antibodies may improve the efficacy to detect atrophic gastritis. Differences between these two Latin American studies are that the gastric cancer mortality rate in Costa Rica is about 2. In another study, conducted in Mexico in 180 healthy volunteers, atrophy was measured in multiple biopsies from antrum and corpus. Thus, more studies are needed in Latin America to better establish the performance of the test and to define cut-off values for the population. Since the test detects atrophic gastritis, it is not effective for screening of diffuse gastric cancer, and performance would vary depending on the proportion of diffuse gastric cancer in the population. Diffuse Intestinal the prevalence of pre-neoplastic lesions would also affect the performance of the test. In addition, the pepsinogen test is still too expensive to use in communitybased screening programmes, particularly in countries in Latin America and Asia that present the highest mortality rates. Still, pepsinogen tests currently represent the most reliable and practical test to screen populations and identify those who deserve close followup by means of invasive endoscopic methods. In particular, patients with atrophic antral gastritis present with low levels of circulating G-17. Current national programmes in Asia Japan and the Republic of Korea, the Asian countries with the highest gastric cancer mortality rates, have national or regional screening programmes to identify early gastric cancer cases. Japan uses barium X-ray as a government-sponsored nationwide programme in asymptomatic individuals older than 40 years. In the Republic of Korea, the National Cancer Screening Program recommends biennial screening for individuals older than 40 years, with direct upper-gastrointestinal series or endoscopy. Novel approaches There are several recent studies searching for markers that may distinguish normal individuals from those with pre-neoplastic lesions, which take advantage of what is being learned about the natural history of gastric cancer. Although they are still far from clinical use or from being recommended in population screening programmes, such markers should be considered for studies in large groups in regions with high gastric cancer mortality rates, particularly in Asia and Latin America, to better elucidate their potential use in a particular population. Clearly, much has been learned about genetic polymorphisms as risk factors for gastric cancer in Asia, particularly Japan and China, but an effort should be made to study this in other human groups with high gastric cancer mortality rates, including other countries in Asia and Latin America. The study of microbiota in the stomach may also show some utility as a marker of risk or prognosis for gastric cancer. Given the diversity of microbiota structure across individuals and across populations, regional studies are needed to gain insight into its diversity in each population. Other considerations It should be kept in mind that gastric cancer is a multifactorial disease and that a proper combination of markers may improve their utility to identify patients at risk. The utility of a biomarker test is optimized when it is applied in the right context. At present none of the suggested biomarkers for gastric cancer has been approved for clinical use, and they are even farther from being ready for use for large-scale screening. When planning for a community screening programme, important points to consider are that the test should be validated for accuracy and high predictive value in the population being studied, and it should be non-invasive, simple, cheap, and accessible. Suggested strategies for Latin America In Latin America, no population strategies have been suggested so far, despite the fact that the region contains areas with gastric cancer mortality rates among the highest in the world. A first approach should consider that the pepsinogen test has not proven as efficient in Latin America as in Asia to detect atrophy. Also important is the reported increasing trend in different countries of the diffuse type of gastric cancer, for which no precancerous lesions have been described yet. Still, an initial selection by country and by district or county might help better target screening programmes. Latin America is a region with limited resources for public health, and an initial screening should be simple and cheap. Probably, after initial selection of districts, screening could be performed in adults older than 40 years for H.
