Malnourished children had significantly higher gastric juice pH in basal and 30-60 minute stimulated samples compared to better-nourished counterparts buy 20 mg geodon fast delivery. Forty percent of the malnourished children and twenty five percent of better-nourished counterparts had Gram- negative bacterial colonization in prestimulated gastric juice samples generic geodon 20mg otc. In the post stimulation period geodon 20 mg without a prescription, gastric juice pH still remained high in the malnourished children, and there was no change in the percent of children with bacterial colonization. However, gastric juice pH dropped down to <4 in the post stimulation period in better-nourished children, leading to a significant reduction in the proportion of samples with bacterial colonization from 25% to 15%. This study showed that hypochlorhydria was evident in both malnourished and better- nourished children, with malnourished children unable to respond appropriate to a stimulus for gastric acid production. As a consequence of hypochlorhydria, bacterial colonization of the stomach was common in malnourished children. Among 48 cases of endoscopically and/or surgically confirmed gastric masses, forty five cases. Thirty nine out of forty five cases of histologically confirmed primary gastric carcinoma were adenocarcinoma which was the commonest histological pattern. Primary gastric carcinomas were commonly found in 51 to 70 years age group (26 cases) and male were slightly more affected than female (1. Twenty six out or 50 cases of gastric masses were polypoid lesion which are the commonest morphological appearance. Forty out of 43 cases of primary gastric carcinoma showed pseudorenal pattern in ultrasound. So pseudorenal pattern was not the specific feature for primary gastric carcionma. Accuracy of ultrasound in evaluating the malignant and benign masses was found to be 93% and accuracy of endoscopy was 97%. After getting relevant history and physical examination by prepared proforma, the patients were divided into two groups, those with gastrointestinal symptoms group and those without gastrointestinal symptoms group according to criteria. Both groups were assessed by following tests: 1) Evaluation of orthostatic changes in blood pressure, 2) blood pressure response to sustained handgrip, and 3) respiratory variation in heart rate (Expiration : Inspiration ratio). After carrying out the above procedures, for the assessment of gastric motility, each and every patients and healthy control subjects underwent measurement of solid meal gastric emptying time by nuclear scintigraphic study at Nuclear Medicine Department, Yangon General Hospital. Then, all results were analysed statistically by using T test for measuring the differences between group means and univariate analysis of variance. It was found that diabetes mellitus influenced very variably on gastric emptying time (i. Upper gastrointestinal symptoms (nausea, vomiting, early satiety and abdominal bloating) alone did not statistically correlate with actual gastric emptying time. Hence, lack of gastrointestinal symptoms does not exclude abnormal gastric emptying and on the other hand, the presence of gastrointestinal symptoms can not be concluded that there will be delay gastric emptying or gastroparesis. Diabetic gastroparesis was correlated with the presence or absence of cardiac autonomic neuropathy and duration of diabetes in this study. In addition to this, it was found that blood sugar level also influence the gastric emptying in diabetes mellitus patients. In this study Escherichia coli was the most commonly identified bacteria in diarrhoea patients and amikacin was the most sensitive antibiotic for diarrhoea cases. Surveillance for rotavirus diarrhea in children <5 years of age was conducted in a tertiary pediatric hospital in Yangon, Myanmar, from January 2002 through December 2003. Stool specimens obtained from children admitted to the hospital for acute diarrhea were tested for the presence of rotavirus by use of an enzyme-linked immunosorbent assay. Diarrhea was the cause of 5671 (18%) of all hospitalizations of children <5 years of age during the 2-year study period (n=30,869). Rotavirus was identified in 923 (53%) of the 1736 stool specimens tested, and rotavirus infection was associated with approximately 10% of all hospitalizations of children. Rotavirus diarrhea most frequently occurred in children 6-17 months of age, and it was more commonly identified in boys (62% of children with rotavirus diarrhea were boys). The seasonal pattern of rotavirus disease mimicked that of diarrheal illness due to all causes, with the peak season for rotavirus disease occurring from November through February (i. During the study period, 53 of the children who were hospitalized for diarrhea died. The present study confirms the importance of the etiological role that rotavirus plays in childhood diarrhea. From December 2001 to September 2003, stool samples were collected from children under five years of age admitted to the three medical wards of the Yangon Children Hospital. The stool samples collected were tested for the presence of rotavirus by enzyme-linked immunosorbent assay. Vomiting was the most common symptom occurring in 79% of children with rotavirus gastroenteritis. Rotavirus is the cause in one half of children under five years of age with gastroenteritis. Endoscopy was performed and although stomach was found to be normal, a rounded spherical shaped tumour of size 1. Histopathologic diagnosis came back as duodenal leiomyoma with no evidence of malignancy.

Plant-derived compounds used as drugs are generally used in ways that correlate directly with their traditional uses as plant 52 medicines discount 20 mg geodon with mastercard. Malaria also causes significant economic damage in high-rate areas buy geodon 20 mg mastercard, and disproportionately 54 affects poor people who cannot afford treatment or have limited access to health care buy geodon 20 mg without a prescription. Traditional medicines are the source of some modern antimalarial drugs (artemisinin and quinine derivatives). Artemisinin was isolated in 1972 as the active ingredient of the plant Artemisia annua, and this innovation relied upon the Chinese traditional medical text, rd 55 Handbook of Prescriptions for Emergencies, written in the 3 century A. Carter, The evolving role of natural products in drug discovery, 4 Nature Reviews Drug Discovery 206-220, 206 (March 2005). A study investigating plant-derived pure compounds used as drugs identified 122 compounds obtained from 94 species of plants. These compounds are used globally as drugs and 80% are used in ways that correlate directly with their traditional uses as plant medicines by native cultures. Farnsworth, The Value of Plants Used in Traditional Medicine for Drug Discovery, 109 Environmental Health Perspectives 69-75, 69 (2001). This process is sometimes referred to as "bioprospecting," the development of new therapeutics from products of nature. On the one hand, bioprospecting can be beneficial to indigenous communities and developing countries. National governments and local communities may receive a portion of revenue from the sale of new medicines developed from traditional resources, and this revenue can support the conservation and sustainable use of biological resources. On the other hand, if unregulated, bioprospecting can result in over-exploitation of limited resources. Habitats that support medicinal plants are being destroyed by over-harvesting and new commercial developments. Many traditional medicines now face extinction with serious consequences for local communities. For example, licorice root, without a doubt the most 59 commonly used Chinese herb is now threatened. Licorice root is now grown in less than 60 half its previous area as a result of excessive harvesting and habitat destruction. Where bioprospecting occurs without benefit-sharing or the consent of source communities it is sometimes referred to as "biopiracy". However, guarding these resources has historically proven challenging due to a lack of national and international regulations and the need for law enforcement. A prominent example includes the patenting of turmeric in the United States of America. It is applied as an antiseptic for cuts, burns and bruises, taken internally for digestive disorders, and applied topically for skin disorders. The patent on "Use of Turmeric in Wound Healing" covered "a method of promoting healing of a wound by administering turmeric to a patient afflicted with the wound". The patent application claimed that this was the first use of turmeric for such a purpose. The issuance of this patent generated international controversy, particularly in India, where it was felt that traditional Indian medicine was being misappropriated. The ensuing public outcry prompted the Indian government to request that the patent be revoked on the basis of lack of novelty due to its known traditional use. In helping defeat the patent, the Indian government provided evidence that this use of turmeric was not innovative. Because novelty is a necessary requirement for patent protection, it is now difficult for any party to patent the use of turmeric for wound healing or to require compensation for this use. In the Beijing Declaration, they recognized the role of traditional medicine in the improvement of public health and supported its integration into national health systems where appropriate. The declaration encourages governments to create or improve national policies on traditional medicine. It also promotes improved education, research and clinical inquiry into traditional medicine, as well as improved communication 62 between health care providers. The knowledge of traditional medicine, treatments and practices should be respected, preserved, promoted and communicated widely and appropriately based on the circumstances in each country. Governments have a responsibility for the health of their people and should formulate national policies, regulations, and standards as part of comprehensive national health systems to ensure appropriate, safe and effective use of traditional medicine. Recognizing the progress of many governments to date in integrating traditional medicine into their national health systems, we call on those who have not yet done so to take action. Governments, international organizations and other stakeholders should collaborate in implementing the global strategy and plan of action. Governments should establish systems for the qualification, accreditation or licensing of traditional medicine practitioners. Traditional medicine practitioners should upgrade their knowledge and skills based on national requirements. The communication between conventional and traditional medicine providers should be strengthened and appropriate training programmes be established for health professionals, 63 medical students and relevant researchers. By 2003, that figure had reached 45, while 51 countries reported national policies pending.
