It is estimated that about 5% to 10% of isocyanate workers develop asthma from exposure to subtoxic levels after a variable period of latency ( 64) generic carvedilol 6.25 mg mastercard. The histology of bronchial biopsy specimens from workers with isocyanate asthma appears very similar to that from patients with immunologic asthma and thus is suggestive of an immunologic mechanism (65) buy generic carvedilol 25mg. Compared with those isocyanate workers with negative bronchial challenges purchase carvedilol 6.25mg free shipping, workers with positive challenges have a higher incidence and level of antibody against isocyanate protein conjugates ( 66) buy carvedilol 25 mg line. However, in most studies, isocyanate workers with positive challenges did not have detectable specific IgE in their serum. In a more recent study, an association between isocyanate asthma and specific IgE was again reported ( 67). Hypersensitivity pneumonitis (68) and hemorrhagic pneumonitis (69) due to isocyanates have been reported to be caused by immunologic mechanisms. Formaldehyde, a respiratory irritant at ambient concentrations of 1 ppm or more, is often cited as a cause of occupational asthma; however, documented instances of formaldehyde-induced IgE-mediated asthma are almost nonexistent (72). A bifunctional aldehyde, glutaraldehyde, has been reported to cause occupational asthma ( 73). Ethylenediamine, a chemical used in shellac and photographic developing industries, has been reported to cause occupational asthma ( 74). Chloramine T (75), reactive azo dyes (76), piperazine acrylates (77), and dimethyl ethanolamine are other chemicals that have also been reported to be causes of occupational asthma ( 78). No matter what the etiologic agent, the presentation follows one of three patterns. Any form can lead to severe pulmonary fibrosis with irreversible change; thus, it is important to recognize this disease early so that significant irreversible lung damage does not occur. A variety of organic dusts from fungal, bacterial, or serum protein sources in occupational settings have been identified as etiologic agents of hypersensitivity pneumonitis (79) (Table 25. Several chemicals, including anhydrides and isocyanates, as discussed previously, have been reported to cause hypersensitivity pneumonitis. It is being increasingly reported that rhinoconjunctivitis precedes occupational asthma in many cases (83,84). Immunologic evaluations may provide important information about the cause of the respiratory disease. Skin tests, with antigens determined to be present in the environment, may detect IgE antibodies and suggest a causal relationship ( 86). Haptens may be coupled to carrier proteins, such as human serum albumin, and used in skin tests (78) or radioimmunoassays. In cases of interstitial lung disease, double gel immunodiffusion techniques may be used to determine the presence of precipitating antibody, which would indicate antibody production against antigens known to cause disease ( 79). It may be necessary to attempt to reproduce the clinical features of asthma or interstitial lung disease by bronchial challenge, followed by careful observation of the worker. Challenge may be conducted by natural exposure of the patient to the work environment with preexposure and postexposure pulmonary functions, compared with similar studies on nonwork days. It is important that the intensity of exposure not exceed that ordinarily encountered on the job and that appropriate personnel and equipment be available to treat respiratory abnormalities that may occur. Some advocate the use of peak flow monitoring, whereas others find it unreliable ( 87,88). Evaluating induced sputum eosinophils has been reported to be a potentially useful technique to diagnose occupational asthma ( 89). All known information about the sources of exposure should be sought in the form of previously reported toxic or immunologic reactions. The obvious conclusion from these studies is that early diagnosis and removal from exposure are requisites for the goal of complete recovery. It must be appreciated that life-threatening attacks and even deaths have been reported when exposure continued after diagnosis (1). Sometimes, the worker can be moved to another station; efficient dust and vapor extraction can be instituted; or the ventilation can be improved in other ways, so that a total job change is not required (96). Consultation with an industrial hygienist familiar with exposure levels may be helpful in this regard. It is important to remember that levels of exposure below the legal limits that are based on toxicity may still cause immunologic reactions. Ideally, the working environment should be designed to limit concentration of potential sensitizers to safe levels. Unfortunately, this is impractical in many manufacturing processes, and even in a carefully monitored facility, recommended thresholds may be exceeded ( 97). Thus, avoidance may well entail retraining and reassigning an employee to another job. However, chronic administration of steroids for occupational hypersensitivity pneumonitis is not recommended.

The sympathetic supply of the stomach was by the greater splanchnic nerves through the coeliac plexus. The roots of the greater splanchnic nerves arose from as high as 4th thoracic ganglion and as low as 10th thoracic ganglion: even variable origins in each side of the same specimen were observed. In the majority of cases, the segmental origin of the greater spanchnic nerve was found to come th th from the 6 to 9 thoracic ganglia (78% on the right side and 84% on the left side). In most of the cases, the parasympathetic nerves were seen to arise from a single anterior vagus and, a single posterior vagus (73. However, in 8 cases, two anterior vagal trunks and one posterior vagal trunk were seen (17. The histological examination of the distribution and the mode of termination of the gastric nerves were determined in the stomachs of 15 human adults, 3 human fetuses, 8 albino rat, and 4 specimens from operative biopsy tissue by using various neurohistological and histochemical techniques. Nerve plexuses and ganglia were observed in the submucosa, muscular, and serosa layers of the stomach. Free as well as encapsulated endings were observed in the wall of the stomach of human and albino-rats. The type of nerve endings were free and free but organized endings such as loop-like endings. Pharmacological experiments were done in the stomachs of 2 albino-rats to prove the sympathetic and parasympathetic activities. Sympatho- mimetic agents were seen to evoke inhibitory responses where parasym-pathomimetic agents were found to evoke excitatory responses. Neurohistological and histochemical studies were done on the specimens from fifteen human adults, three human fetuses, eight albino-rats, and four specimens from human operative biopsy tissue. All parts of the stomach were supplied by the gastric branches of the coeliac plexus formed by both th th vagi and greater splanchnic nerves mainly from 6 to 9 thoracic ganglia. Neurohisto- chemically nerve plexuses and ganglia were observed in the submucosa, muscular, and serosa layers of the stomach. Intraepithelial free nerve endings, free but organized nerve endings such as loop-like endings and encapsulated endings such as Meissner s corpuscle and small bulbous corpuscles were 190 Bibliography of Research Findings on Gastrointestinal Diseases in Myanmar seen. Histochemicaly, acetylcholinesterase - positive ganglia, varicose nerve fibres and formaldehyde fluorescent nerve plexus were observed. Pharmacological experiments with sympathomimetic agents, sympatholytic agents, parasympathomimetic agents, and parasym- patholytic agents were done in the stomachs of two albino-rats to prove the sympathetic and parasympathetic activities. The review also outlines the rational approach to promotion of growth of Myanmar children. Studies conducted in Myanmar have shown that rice malabsorption is common in children, and may occur in up to two thirds of the population. It is possible that Helicobacter pylori infection frequently acquired during childhhod in developing countries has an impact on small bowel function. The precise mechanism is unknown but it has been proposed that it relates to the impact of infection on acid secretion, resulting in hypochlorhydria which may open the gate to enteric infections, small bowel bacterial overgrowth, and associated carbohydrate malabsorption. Elucidation of these mechanisms would allow a rational approach to promotion of growth of Myanmar children. An increase in the number of siblings was also found to be a high risk factor for H. Density of living, drinking water source, and type of latrine were not significantly associated with H. The findings indicated that intrafamilial transmission could play an important role in the high prevalence of H. Before implementation of clinical use of such a serological test requires validations for local use. Again growing popularity of "test- and-treat" policy requires evaluation of usefulness of such serological test-performance among under and over forty-five years age groups. The objectives were: a) to compare the gastric acid secretion together with urine acid output between malnourished and well-nourished children, b) to determine the relationship between the gastric acid secretion and urine acid out put. The study was carried out during June to December 2000 at the Yangon Children Hospital. Gastric acid secretion and urine acid output level before and after coffee stimulation in 40 malnourished and 20 well-nourished children. It was found that there was significantly decreased volume of stimulated gastric acid secretion within first hour (17. However, there was no significant quantitative relationship between gastric acid secretion and urine acid output in both malnourished and well-nourished children. Malnourished children were unable to respond appropriate to a stimulus for gastric acid production, poor response was markedly observed in children with kwashiorkor and lesser extent in marasmic-kwashiorkor children. All these patients underwent semi-urgent haemorrhoidectomy (Standard Ligation and Excision).
