Clinical presentation of hypersensitivity pneumonitis The acute form is commonly confused with atypical cheap proventil 100mcg line asthma definition who, community-acquired pneumonia. Diseases such as humidifier fever also can occur in outbreaks and may be related to inhalation of endotoxin from gram-negative bacteria that contaminate ventilation and humidification systems (41). Evaluating chronic interstitial lung disorders in the differential diagnosis of chronic hypersensitivity pneumonitis The differential diagnosis of the subacute form of hypersensitivity pneumonitis includes chronic bronchitis, recurrent episodes of influenza, and idiopathic pulmonary fibrosis. Extrapulmonary findings of liver or spleen enlargement, generalized or local lymphadenopathy, severe sinusitis, or myositis are not consistent with hypersensitivity pneumonitis. Several animal models and many animal studies have been conducted to elucidate the complexity of the inflammation of hypersensitivity pneumonitis ( 42,43,44 and 45). Unfortunately, the findings do not appear to directly parallel the cellular infiltrate seen in human disease. Also, there is difficulty evaluating exposed but asymptomatic animals, as can be done in human studies. Human studies are more difficult to perform, relying on patients who have already experienced symptoms and therefore not truly evaluating the course of inflammation from the onset. The relative contributions of cellular versus humoral immunity in the pathogenesis are not entirely defined. A case report of a patient with hypogammaglobulinemia and hypersensitivity pneumonitis supports the central role of cellular immunity in mediating the disease ( 47). The study data are frequently based on bronchoalveolar lavage findings compared with biopsy or peripheral blood. The neutrophils release superoxide anions, hydroxyl radicals, and toxic oxygen radicals, which contribute to the inflammation. Cigarette smoking may provide a protective effect from hypersensitivity pneumonitis by decreasing the expression of B7 + costimulatory molecules, whereas viral infections could enhance hypersensitivity pneumonitis by increasing B7 expression. E Increased expression of the integrin a b7 on the surface of T cells function as mucosal homing receptors for the selective retention of T lymphocytes in lung mucosa (52). Surfactant is responsible for the regulatory activities of lung lymphocytes and alveolar macrophages. Thus, the alveolitis in hypersensitivity pneumonitis also may be due in part to alteration in the surfactant immunosuppressive effect. Viruses including influenza A have been demonstrated by polymerase chain reaction in the lower airways of patients with acute hypersensitivity pneumonitis. In experimental murine models infected with respiratory syncytial virus, both the early and late inflammatory responses are augmented in hypersensitivity pneumonitis. Further studies are required to clarify the nature of this relationship between viral infection and the modulation of pulmonary immune response ( 55,56). Although this straightforward approach is simple to recommend, adherence by patients can be more difficult. Machinists with metal-working fluid induced lung disease may be unable to work in other capacities. Although elimination of the antigen seems essential for a long-term solution to the problem, continued antigen exposure may not lead to clinical deterioration for some persons ( 57). Depending on the source of the antigen and the conditions surrounding its generation, various industrial hygiene measures have been proposed. Other measures include alterations in plant management, increased automation, improved exhaust ventilation, and personal protective face masks. Frequently, assays for the presence of the material in the environment are lacking, or the minimum concentration to provoke symptoms or initiate sensitization is not known. Pharmacologic Treatment Few data exist on the various pharmacologic treatments for hypersensitivity pneumonitis. Corticosteroid therapy should be instituted in the acute and subacute forms because this has been reported to reduce symptoms and detectable inflammation and improve pulmonary function. Oral corticosteroids are recommended for acute disease starting at prednisone doses of 40 to 80 mg daily until clinical and laboratory improvements are observed, then decreased stepwise to 5 to 10 mg every other day for six weeks. Ongoing follow-up visits should include pulmonary function studies, not peak flow measurements, because they are not sensitive enough. If obstructive pulmonary function changes are present, then treatment with bronchodilators can be attempted. As in other occupational lung diseases, a systematic evaluation and investigation of the work environment and exposed cohort is recommended, although not mandated by law or always conducted ( 59). The investigation for additional cases may include a screening questionnaire survey with positive responses undergoing chest radiographs, serum precipitins, and lung function testing. Questionnaire surveys can be used to screen for further cases of disease, and to compare rates of symptoms between different locations in the same plant. Survey questions should include demographics, risk factors, and protective factors in the home and workplace, including tobacco use and the presence of a humidifier/dehumidifier. Although most cases of acute disease improve, those patients with ongoing exposure continue to experience symptoms, and have abnormal lung function and abnormal chest radiographs. Efforts are needed to prevent recurrent and progressive disease in individuals already sensitized and prevent potential epidemics in occupational settings.

A total of 3640 cases of diarrhoea and 3279 age- and sex-matched controls were studied; about 60% of the patients were aged less than 1 year and 60% were male cheap proventil 100mcg overnight delivery asthma symptoms rubric. In all the study centres discount proventil 100 mcg without prescription asthma definition revenant, the pathogens most strongly associated with disease were rotavirus (16% of cases discount 100mcg proventil otc asthma definition 6 atlanta, 2% of controls) purchase 100mcg proventil with amex asthma definition nz, Shigella spp. Rotavirus was commonest among 6-11-month-olds, accounting for 20% of all cases in this age group; 71% of all rotavirus episodes occurred during the first year of life. The proportion of cases that yielded no pathogen was inversely related to age, being highest (41%) among infants below 6 months of age and lowest (19%) among those aged 24-35 months. These results suggest that microbe-specific intervention strategies for the control of childhood diarrhoeal diseases in developing countries should focus on rotavirus, Shigella spp. Methods: The study was undertaken in Burma on 33 children aged 18 months to 12 years. Thirty three patients (55%) were found to be associated with enteropathogenic bacteria. Biopsy findings of gastric ulcers and, operative findings of all cases st th were recorded. There were 42 patients with radiologically diagnosed gastric ulcers, 26 cases had benign gastric ulcers and 16 cases had malignant gastric ulcers. Therefore a laboratory profile of acute and persistent 90 diarrhoea in children admitted to Paediatric Unit xecluding Special Care Baby Unit of Mandalay General Hospital had been done during June 1996 to October 1996 with the following objectives. Out of a total 184 stool culture, the commonest bacterial pathogen isolated was enteropathogenic E. In children with persistent diarrhoea, out of total 16 stool culture done, 50% revealed positive culture. Out of this total 200 cases with diarrhoeal diseases, 16 cases (8%) had persistent diarrhoea. Abdominal pain, tenemus and muscle cramp were more marked in persistent diarrhoea 31. In conclusion, the causal organism in children with acute and persistent diarrhoea had been isolated in about 50% of cases. The common protozoa and worm infestation were Entamoeba histylitica, Giadia lamblia, Ascaris lumbricoid and tricuris trichura. In children with persistent diarrhoea, more combination of infection or infestation was detected. So more antimicrobial therapy was found to be given in all persistent diarrhoeal patients. Also the usage of antibiotics in acute diarrhoeal cases should be minimized to actual indiacted cases. Bacteria isolated from the jejunal fluid in upper small intestines of these children were incubated with lactulose at neutral pH. Anaerobes were present in all but one child, and in 15 children they were present in numbers greater than 5 log 10 organisms per ml. This study suggests that in the diagnosis of small bowel bacterial overgrowth using lactulose breath hydrogen test, it is important to consider that patients with a flat breath hydrogen response to a carbohydrate challenge during the first 60min may be infected with enteric bacteria which are not capable of producing H2. Rotavirus was detected by enzyme linked immunosorbent assay in stools of 43 children. Cases were 67 children 1-59 months old hospitalized for diarrhoea lasting >14 days and complicated by severe malnutrition; for each case, a healthy control child was selected who was age- and sex-matched from the same neighbourhood. Homes of cases and controls 92 Bibliography of Research Findings on Gastrointestinal Diseases in Myanmar were visited for interviews and for direct observation of household child-care practices. Risk factors were catalogued and calculations made for relative risk and etiologic fractions. These results indicated that persistent diarrhoea and malnutrition in Burma is caused by a complex of several interrelated socioeconomic factors, unsanitary behaviour pertaining to personal hygiene, the practice of demand breastfeeding and lack of certain weaning foods, and low education of mothers who showed less knowledge about causes of diarrhoea and prevention of malnutrition. Glycine 4g and glycyl-glycine 4g patients with clinical cholera were given tetracycline 500mg q. Rectal swabs were also taken and investigated for culture and sensitivity at the Bacteriology Research Division of the Department of Medical Research. A total of 200 children under five years of age with acute diarrhoea were included in the study. Sixteen serogroups were identified 94 Bibliography of Research Findings on Gastrointestinal Diseases in Myanmar O125 and O126 were common serotypes. The serogroups of Escherichia coli classified were O1 K51; O8K25; K+; O25K+; O27K+; 028K+; O78K+; O86 K61, K62; O114 K90; O119 K69; O125 K70; O126 K71; O127 K63; O128 K67; O136 K78; O148 K+; O157 K+ and O159 K+. It was also noted that personal hygiene still plays an important role in causing acute diarrhoea. As peptic ulcer disease is very common in Myanmar, it is of great importance to elucidate whether H. A total of fifty biopsy specimens which were obtained from forty-three male and seven female patients were included in this study. Patients of age range forty-five and above forty-five years were observed to be of highest prevalence consisting of 44 percent. These patients had undergone endoscopic examination and the respective biopsies were taken. The invasive tests used in this study were rapid urease tests, histology and culture. Among the fifty patients studied, 95 Bibliography of Research Findings on Gastrointestinal Diseases in Myanmar thirty five patients (70%) were urease positive, twenty patients (40%) were positive on histological examination and ten patients (20%) were positive on bacteriological examination. The sensitivity and specificity of urease test, histology and culture were 90% and 35% for urease test, 50% and 62. The study included fifty biopsy specimens obtained from forty three male and seven female patients. These patients were submitted to endoscopic examination and the respective biopsies were taken. The sensitivity and specificity of urease test, histology and culture in the diagnosis of H. The endoscopic study from 50 patients revealed, 18 patients with only gastritis (36%); 19 with gastritis and duodenal ulcer (38%); 6 with gastritis and gastric ulcer (12% and with gastritis, duodenal and gastric ulcer (14%). Factors associated with duration of diarrhoea were ascertained by multiple regression analysis, where as prognostic indicators were confirmed by simple logistic regression procedure. Positive association with duration of diarrhoea of diarrhoea 96 Bibliography of Research Findings on Gastrointestinal Diseases in Myanmar noted with presence of mucus/blood/both in stool, decreased weight for age, lower income group and non-use of soap in hand washing after defecation. In addition to these factors lack of exclusive breast feeding in under 2 years children had positive association with duration of diarrhoea. In a logistic regression analysis, malnutrition, lack of hand washing with soap after defecation and lack of exclusive breast feeding were found to be prognostic indicators for the development of persistent diarrhoea. Endoscopic antral biopsy tissues for urease testing and 14C urea breath test confirmed the diagnosis of H. A total of 487 children, 327 with acute and 160 with persistent diarrhoea participated in the study, intestinal pathogen was detected in 71% (114) of persistent diarrhoea cases including bacteria agent 31%, viral agent 6.

In this period bacterial infections and dis- generations with improved efficacy and broad spectrum eases were considered the diseases of the past (Box 1). The golden age of antimicrobial therapy began with the production of penicillin in 1941 to the discovery of 1.

Synthetic tailoring is widely used to create successive generations of antibiotic classes.

It is estimated that about source of information on the drugs and offers improved 100,000 tons of antibiotics are produced globally [2-4,6]. In most cases, to even the non-healthcare providers such as the patients, it is reported that drug promotions are associated with consumers and the communities. It is a The increased revenue generated by altered prescribing common problem and it s exacerbated by the increased practices in response to drug promotion is considered by marketing and promotion of these drugs directly to the pharmaceutical companies as a direct return on invest- consumers.

Antibiotics are chemical substances naturally produced by various species of microorganisms such as bacteria, fungi, actinomycetes and streptomy- ces that kill or inhibit the growth of other microorganisms [1-4]. Antibacterial agents or drugs are chemical substances that inhibit bacterial growth and their multiplication or directly kill bacterial organisms [1-4]. Antimicrobial agents or drugs are chemical substances that destroy various microbial agents including bacteria, viruses, fungi and protozoa organ- isms [1-4]. Golden age of antibiotics is the period when the entire antibiotics/antibacterial drug spectra were discovered and in this period almost all bacterial infections were treatable with these drugs [4,7]. Drug promotion is defined by the World Health Organization as all informational and persuasive activities by manufacturers, the effect of which is to induce the prescription, supply, purchase and/or use of medicinal drugs [15-18].
