The trend of mortality rate declined significantly in Rangoon buy linezolid once a day, but in other towns linezolid 600 mg fast delivery, the trend was fluctuating buy linezolid overnight delivery, showing occurrence of epidemics. The rise in incidence started from the dry month of April and the peak in July and August coincided with fly season as well as ripening of fruits. Generally, Upper Burma had the highest incidence rate, Lower Burma had the lowest. Males had markedly the higher rate than females, since they are more gregarious and range more widely in their activities and are consequently exposed to greater risk of infections. The sex differences are minimal for infants and pre- school children and are higher for old ages. Summing up Studies of intestinal helminthiasis now included clinical description as well as epidemiolgical surveys which extended to many more locations and communities throughout the country. The important role of Ascaris lumbricoides infection in the pathogenesis of bile duct stones became apparent when analysis of bile duct stones showed the presence of Ascaris ova in their core. Study of gut infection expanded to include intestinal amoebiasis and its treatment with emerging drugs Diagnostic methods began to be systematically studied as new methods were introduced or adapted - evaluation of tetracycline fluorescent test for diagnosis of cancer stomach; development of cholera diagnostic sera. Description of vascular supply of the gut was extended to include other parts of the gut colon, etc. Histological studies were started comparing histology of stomach in vertebrates and histological description of oral mucosa in Burmese subjects. Physiological studies of intestinal absorption were introduced and carried out on healthy Burmese subjects - lactose tolerance and xylose absorption tests. Specific gastro-intestinal diseases which were frequently encountered in hospital practice began to be studied systematically from different aspects according to scientific importance, interest and opportunity: - Peptic ulcer- epidemiology, comparison of surgical treatment, and effect of truncal vagotomy on gastric acid secretion were investigated; peptic ulcer and gastritis were studied for the first time in Myanmar from the new perspective of H. The prevalance of helminthic infections by age, sex and type of parasite was described. The total of 97 patients was all Burmese and included 25 women none of whom was pregnant or lactating. Lactose intolerance was tested for by determining the rise in blood glucose level 30 minutes after an oral dose of lactose 1g/kg body weight and of glucose 0. Out of 31 adults who showed a rise in blood glucose of more than 20mg/100ml after oral glucose 29(93 percent) failed to show a similar rise after lactose, therefore indicating intestinal lactase deficiency. The totals of 97 patients were all Burmese and included 25 women none of whom were pregnant or lactating. Lactose intolerance was tested for by determining the rise in blood glucose level 30 minutes after an oral dose of lactose 1gm/kg body weight and of glucose 0. Out of 31 adults who showed a rise in blood glucose of more than 20mg/100ml after oral glucose 29(93 per cent) failed to show a similar rise after lactose, therefore indicating intestinal lactose deficiency. Out of 17 children who showed a rise in blood glucose of more than 20gm/100ml after oral glucose 11 (64 per cent) did not show a similar rise after lactose, indicating lactose deficiency. Commonly encountered helminthic infections are certain intestinal helminths and Wucheren bancrofte. Among the intestinal helminthc Ascaris, hook-worm and Tricuris are three most prevalent infections. Ascaris infection is found in all age groups, with high incidence in pre- school and school children. Hook-worm infection rate is low in children and it is high in young adults and old people. Delta Region, Kachin State and Tenasserim Division are areas with high prevalence rates of hook-worm infection, where as it is low in dry zone and parts of Shan states. Ascariasis may be a contributing factor in rnalnutrition, but direct evidence is not yet available. Many features of filariasis are encountered in hospital practice, but no consolidated information is available. Present control measures for intestinal helminthiases are just a part of general health measures. Filariasis control is available Rangoon only, and mass chemotherapy, and anti-vector measures are vigorously applied. Also a statistical survey on incidence of the gastro-duodenal lesions in general with special reference to haematemesis and the evaluation of the results of surgery on bleeding peptic ulcers of both duodenal and gastric. The prevalence of helminthes and protozoa among leprosy patients belonging to the sanatorium was equally high as these patients belonging to hospital and out patients department, though the sanatorium had a comparatively high sanitary environment. The prevalence of Strongyloides stercoralis among patients with lepromatous leprosy is significantly high when compared to those with non lepromatous leprosy and controls. This may be due to impaired cell mediated immunity which is associated with lepromatous leprosy.

When treatment of the underlying cause plus antibiotics and bronchial hygiene does not lead to improvement purchase linezolid with amex, surgery can be considered if the bronchiectatic airways are mostly limited to one part of the lung order linezolid discount. Surgery is also considered when persistent infections lead to destruction and bleeding that cannot be controlled by other measures linezolid 600mg mastercard. There are however no controlled studies to determine if surgery is more beneficial than non-surgical treatment. Hospital-acquired or nosocomial pneumonia which have a far higher mortality rate, are usually bacterial in origin, although viral infections can also occur, particularly if hospital personnel with acute viral infections come to work and then spread their infection to patients. The risk for pneumonia is increased in patient populations due to immune suppression or underlying cardiopulmonary functional impairment. Pneumonia Pneumonia is an infection of lung tissue involving the alveoli where gas exchange takes place. Infections that produce pneumonia often do so by causing the alveoli to fill with inflammatory cells and fluid. Everyday, bacteria are inhaled into the lower airways without causing bronchitis or pneumonia. When pulmonary infections occur, it is the result of a virulent organism, a large dose or an impaired immune system. All of us aspirate small amounts of upper airway secretions every night, but as a percent of the population very few individuals actually develop pneumonia. Atypical pneumonias are most commonly due to viruses, Mycoplasma pneumoniae and Legionella pneumoniae. Pneumonia also commonly occurs in patients who have coexisting illnesses which alter the clinical presentation. Severity assessment scores have been developed to improve early identification and hopefully decrease mortality rates in these patients. The organism responsible for causing a patient s pneumonia can be predicted by the status of the patient s underlying immune system and other coexisting diseases, as well as their place of residence - the community or a hospital/chronic care facility. The most common bacterial organism responsible for community- acquired infection in all types of patients is Streptococcus or Pneumococcal pneumoniae. Common Organisms Responsible for Community-Acquired Pneumonias Streptococcus or Pneumococcal pneumonia is a Gram-positive, lancet-shaped diplococcus and is the most common cause of community acquired pneumonia in all populations, regardless of age or coexisting disease. Eight-five percent of all pneumococcal pneumonias are caused by any one of 23 serotypes. The pneumococcal vaccine (Pneumovax) provides protection against all 23 serotypes. Infection is the most common in the winter and early spring, and therefore it is not surprising that many patients report have a preceding viral illness. Spread is from person-to-person and pneumonia develops when colonizing organisms are aspirated at a high enough dose to cause infection. Patients with an intact immune response present with the typical pneumonia syndrome of abrupt onset of a febrile illness, appearing ill or toxic with a cough productive of rusty colored sputum and complaining of pleuritic stabbing chest pain. Physical examination of the chest may show evidence for consolidation with absent breath sounds. Bacteremia (organisms in the blood) can occur in 15 to 25% of all patients and mortality rates are substantially higher in such cases. While penicillin or erythromycin can be prescribed, current treatment for outpatients with community-acquired pneumonia usually includes macrolides such as azithromycin (Zithromax) and clarithromycin (Biaxin), based on an easier to comply with dosing interval and less gastrointestinal side effects. Also used are oral beta-lactams such as cefuroxime, amoxicillin, or amoxicillin- clavulanate. Fluoroquinolones with activity against Streptococcus pneumonia (such as Levaquin and Avelox) can be substituted when needed though some recommend against the use of this class of antibiotics as first-line therapy due to risk of developing resistance. Ten percent of strains in the United States are intermediately resistant to penicillin but can still be treated with high dose penicillin, while one percent are highly resistant and require treatment with Vancomycin. As is often the case in any type of pneumonia, radiographic improvement lags behind the clinical response and may take months to clear and become normal. Legionella pneumonia is a Gram-negative bacillus first characterized after it led to a pneumonia epidemic in Philadelphia in 1976. Retrospective analysis of stored specimens has shown that Legionella pneumonia has caused human disease since at least 1965. At least 12 different serogroups have been described, with serogroup 1 causing most cases. When a water system becomes infected in an institution, endemic outbreaks may occur, as has been the case in some hospitals. Person-to-person spread has not been documented, nor has infection via aspiration from a colonized oropharynx, although it may be possible that the infection can develop after subclinical aspiration of contaminated water. Patients with Legionella pneumonia commonly present with high fever, chills, headache, body aches and elevated white blood cell counts. The patient may have a dry or productive cough, pleuritic stabbing chest pain, and shortness of breath. The chest radiograph is not specific and may show bronchopneumonia, unilateral or bilateral disease, lobar consolidation, or rounded densities with cavitation. Symptoms are rapidly progressive, and the patient may appear to be quite ill or toxic.
