Cholera usually starts at the begining of summer in March and reached epidemic proportion in April and May with peak in May purchase cefadroxil 250 mg mastercard, and subsides when the rain fall in June buy cefadroxil 250mg otc. Course undertook an epidemiological investigation of parasitoses in Dayebo Village, Hlagu Township. A representative sample of 130 households (50 percent of the population) composed of 645 individuals were investigated. These were preserved in well marked containers containing 5ml of 5 percent formal- saline preservative. Of the total specimens the prevalence rates for specific helminthic infections were: 69 percent for strongyloidiasis. It should be borne in mind that these estimates are minimum estimates as they are based on a single preserved stool specimen. Had more specimens been taken, some of the negatives would have been found positive. Age, sex, family size and patterns of these infections were analyzed and discussed. Age and sex patterns for egg counts and worm loads for asariasis and trichuriasis (the commonest helminthic infections) are reported. In conclusion intestinal parasitoses constitute a major health problem in this community. It is recommended that a nationwide investigation of parasitoses in Burma be organized, has accordingly long term and short term preventive and curative measures be undertaken. Stool specimens were examined directly and after concentration by the formal-ether method of Ritchie (1948) as modified by Ridley and Hawgood (1956). A four factor analysis of variance for parasite, region, age, and sex and their interaction showed no significant differences. Coverglass preparations of faces were examined directly in normal saline, 1 percent eosin and Lugol s iodine respectively. Each specimen was re-examined after concentration by the formal ether method of Ritchie as modified by Ridley and Hawgood (1956). Male students had higher rates of infections with hookworm and Strongyloides stercoralis. Out of a total 393 individual examined, ranging a age from 5-25 years, 215 were from Bassein town and 178 individuals from Kozu Village. There was no significant difference between the overall prevalence of parasites at Bassein town and Kozu village. The prevalence of helminth infections was found to be significantly higher in the urban group, while protozoa infection were significantly more prevalent in the rural group. Younger age groups have a higher helminth infection rate in Bassein Town as well as Bassein Township. The findings of survey was compared with those of other studies in Burma and discussed. The Augmented Histamine Test carried out by the Department of Physiology, Institute of Medicine, Mandalay, during the last two years is described. The Histamine Infusion test which promises to be a better and more reliable test of gastric secretory activity is described. Trials have been conducted on radiologically proven duodenal and gastric ulcer patients as well as normal subjects. The reliability of the test has been compared against that of the Augmented Histamine Test. The continuous Subcutaneous Histamine Test has been found to possess the same range of applicability as Augmented Histamine Test with the added advantage of requiring only simple equipment. The test can safely be used as a routine test in district hospitals where elaborate equipment is not available. Each group of 200 persons were vaccinated with classical cholera vaccine El Tor cholera vaccine and mixed cholera vaccine respectively. The purpose of this sera study is to assess the antigenicity levels of antibodies response with the 3 types of vaccine. A total of 15,000 working people from various factories were grouped into 3 groups and were inoculated and rise response in each individual varied considerably in all 3 groups. Of the 3 kinds of vaccines tested, El Tor vaccine showed a better response to the local strain prevalent in Rangoon. Various patterns not conforming to descriptions given in standard text-books on Anatomy are frequently reported together with statistical figures for each pattern. In an attempt to compile such a statistical record of the various patterns prevalent in our country, we have maintained a close observation on the manner of origin, course and distribution of all arteries supplying the gastro intestional tract of subjects made available to our Dissection laboratory. Younger age groups are included in larger proportion and many lives were lost due to the bleeding.

Health intervention during disaster Health activities during disaster include developing health action plans and taking appropriate interventions during 250 mg cefadroxil with visa. Every time a disaster is anticipated purchase 250 mg cefadroxil, a health plan should be prepared at any level of the health system. The plan should include the following tasks: Health and nutritional surveillance of the affected areas. Management of acute illnesses In epidemics, local health services will have the responsibility for diagnosis and treatment of the increasing number of cases during the initial phases. The local availability of trained health personnel, basic diagnostic facilities and essential drugs and vaccines are essential for fighting outbreaks and reducing the mortality rate. Furthermore, it is important to have pre-established and readily available standardized treatment protocols and procedures which are well known to the health personnel. In principle, the three main methods of control are dealing with the source of infection; interrupting transmission; and protecting susceptible individuals (see the details on chapter two).

Look at the number of malaria cases at specific health facility or district by month for the past 5 years excluding epidemic years. Determine the 3 quartile for the monthly th series by identifying the 4 highest number from the bottom in each data series (since data is ranked in ascending order). This is rd the 3 quartile representing the upper limit of the expected normal number of malaria cases. Plot the 3 quartile for each data series by months for the 5 year period and join the points with a line. Plot the monthly malaria cases that visited a health facility and compare with the third quartile or the norm-chart. If the number is 194 Manual on Investigation and Management of Epidemic Prone Diseases in Ethiopia rd above the 3 quartile (upper limit), this is an indication of a possible malaria epidemic. Example: Number of malaria cases in certain health facility by month for consecutive five years along with rd the median and the 3 quartile for each month for the five year is shown in the table below.

This can be also taken as a sample to prepare epidemic preparedness and response plan in the context of specific disease entity using the same steps (see annex 1). Before measles vaccine became available, virtually all individuals contracted measles with an estimated 130 million cases each year.

B lymphocytes responding to T-dependent antigens require two signals for proliferation and differentiation: (a) the binding of their surface immunoglobulin by appropriate specific antigen purchase cefadroxil 250mg fast delivery, and (b) the binding of cytokines (e buy cefadroxil 250mg mastercard. The help provided by T cells acts only over a short range; thus, the T and B cells must be in fairly intimate contact for these interactions to occur successfully. Splenic or lymph node T cells (or both) from the individual in question (responder) are mixed with lymphocytes from another individual (sensitizer) against whom the response is to be evaluated. The two cell populations are incubated together for 4 to 5 days, after which time tritiated thymidine is added to the culture for a few hours. If the responder cells actively proliferate as a result of the recognition of foreign antigens on the sensitizing cells, significant increases of thymidine incorporation (over control levels) can be measured. Individuals presensitized against a particular antigen, then later challenged intradermally with a small amount of the same antigen, display local inflammatory responses 24 to 72 hours later at the site of challenge. Perhaps the best known example is a + positive tuberculin skin test (Mantoux test). The activated macrophages exhibit an increased size and activity, enabling them to destroy and phagocytize the antigenic stimulus. However, because macrophages are not antigen specific, they may also destroy normal cells and tissues in the local area, referred to as innocent bystander destruction. In this regard, the immune system provides the body with a means for minimizing or preventing disease. This is most clearly illustrated by individuals who have defects in immune function (immunodeficiency disease) resulting from genetic, developmental, infective, or therapeutic causes. Because of its destructive potential, however, the immune system is also capable of causing disease when confronted with inappropriate antigenic stimulation or loss of regulatory control ( 88). Transplantation Transplantation involves the ability to replace damaged or diseased body parts by transplanting organs from one individual to another. Unfortunately, the immune system is exquisitely adept at recognizing nonself and rejecting transplanted organs from donors differing genetically from the recipient ( 89). Because a genetically perfect match between host and donor in humans exists only between identical twins, transplantation surgeons are forced to minimize or eliminate the recipient immune response against the transplanted organ. Ideally, only the ability of the immune system to react to the antigens on the transplanted organ would be diminished (i. However, we currently must rely on drugs that depress the immune system in a relatively nonspecific fashion, thus leaving the patient susceptible to potentially fatal opportunistic infections. Bone marrow transplantation represents a special case in which the graft itself comprises immunocompetent tissue and the host is either immunodeficient or immunosuppressed. There are several possible scenarios under which such undesirable responses might be initiated. Autoimmune responses may arise when antigens that have been normally sequestered from the immune system (e. Having never been detected previously by the immune system as it developed its sense of self versus nonself, such antigens are now seen as foreign. Third, immune responses against determinants on infectious agents may generate clones of lymphocytes with receptors capable of cross-reacting with self antigens (cross-reactive antigens). A classic example is rheumatic fever, which results from immune responses against streptococcal antigens that are cross-reactive with molecules found on cardiac tissue. For example, the onset of systemic lupus erythematosus is associated with age and an accompanying decline in suppressor T-cell function. Immune Complex Diseases The humoral immune response is generally efficient in eliminating antigen antibody complexes through the phagocytic cells of the reticuloendothelial system. There are, however, situations in which antigen antibody complexes (involving IgG and IgM antibodies) reach such high concentrations that they precipitate out of solution and accumulate in tissues, often unrelated to the source of the antigen. This may lead to systemic or localized inflammation as the complexes bind and activate serum complement components, attract phagocytic cells, and induce the release of proteolytic enzymes and other mediators of inflammation. Attempts to clear depositions of antigen antibody complexes often damage the tissues and organs involved. Such situations most often arise as a secondary effect of situations in which there is a persistence of antigen (e. Among the most commonly damaged sites are the kidneys, of which the filtration apparatus tends to accumulate deposited complexes (glomerulonephritis); the synovial joint membranes (rheumatoid arthritis); the skin (rashes); and the endothelial walls of blood vessels (arteritis). Contact Dermatitis Contact dermatitis is an example of a normally protective T-cell mediated immune response that becomes harmful under certain circumstances. Allergies and Anaphylaxis (Immediate Hypersensitivity) Allergies and anaphylaxis represent antigen-specific immunologic reactions involving IgE antibodies bound (by their Fc domain) to the membranes of mast cells and basophils (95). Immediate hypersensitivity may develop against a wide array of environmental substances and may be localized (e. For example, autoimmune responses, asthmatic and allergic responses, and the host responses against transplanted tissues or organs all represent situations in which such tolerance would be desirable.

Chronic otitis media with effusion and adenotonsillectomy: a prospective randomized controlled study. People at risk are often very anxious about future stings and modify their daily living patterns and lifestyles. Major advances in recent years have led to appreciation of the natural history of insect sting allergy and appropriate diagnosis and treatment for people at risk for insect sting anaphylaxis. For most affected people this is a self-limited disease; for others, treatment results in a permanent cure. The identification of the culprit insect responsible for the reactions is thus important in terms of specific advice and specific venom immunotherapy discussed later. Because of the common use of the honeybee for the production of honey and in plant fertilization, exposure to this insect is quite common. Multiple stings from honeybees may occur, particularly if their hive, which may contain thousands of insects, is in danger. The honeybee usually loses its stinging mechanism in the sting process, thereby inflicting self-evisceration and death. The problem of multiple insect stings has recently been intensified by the introduction of the Africanized honeybee, the so-called killer bee, into the southwestern United States (1). These bees are much more aggressive than the domesticated European honeybees that are found throughout the United States. The Africanized honeybees entered South Texas in 1990 and are now present in Arizona and California. It is anticipated that these bees will continue to spread throughout the southern United States. They are unable to survive in colder climates but may make periodic forays into the northern United States during the summer months. These insects nest in the ground and are easily disturbed in the course of activities, such as lawn mowing and gardening. They are also attracted to food and commonly found around garbage and picnic areas. They are present in increasing numbers in late summer and fall months of the year. Hornets, which are closely related to the yellow jacket, nest in shrubs and are also easily provoked by activities such as hedge clipping. Wasps usually build honeycomb nests under eaves and rafters and are relatively few in number in such nests. However, in some parts of the country, such as Texas, they are the most common cause for insect stings. In contrast to stinging insects, biting insects such as mosquitoes rarely cause serious allergic reactions. These insects deposit salivary gland secretions, which have no relationship to the venom deposited by stinging insects. Isolated reports also suggest that, on a rare occasion, mosquito bites have caused anaphylaxis. It is much more common, however, for insect bites to cause large local reactions, which may have an immune pathogenesis (2). Large Local Reactions Extensive swelling and erythema, extending from the sting site over a large area is a fairly common reaction. The swelling usually reaches a maximum in 24 to 48 hours and may last as long as 10 days. Most people who have had large local reactions from insect stings will have similar large local reactions from subsequent re-stings ( 3). Thus, people who have had large local reactions are not considered candidates for venom immunotherapy (discussed later) and do not require venom skin tests. Anaphylaxis The most serious reaction that follows an insect sting is anaphylaxis. Retrospective population studies suggest that the incidence of this acute allergic reaction from an insect sting ranges between 0. Allergic reactions can occur at any age; most have occurred in individuals younger than 20 years of age, with a male-to-female ratio of 2:1.

Selegiline cefadroxil 250 mg cheap, an inhibitor of monoamine oxidase B may delay the need to start levodopa and may slow the rate of progression of the disease discount 250 mg cefadroxil free shipping, but has significant side-effects. Levodopa is usually used in combination with a selective dopa decarboxylase inhibitor which does not cross the blood brain barrier and reduces peripheral adverse effects. The commonest side-effects are nausea, vomiting, dizziness, postural hypotension and neuropsychiatric problems. After many years of treatment the effects tend to diminish and the patient may develop rapid oscillations in control the on off effect. When these develop, a sustained release for- mulation of levodopa or a dopamine agonist, e. Because of the loss of effect with time, treatment should not be started too early. She should be assessed by a physiotherapist and occupational therapist and provided with advice and aids. This has progressed so that she is now short of breath on walking up one flight of stairs and walks more slowly on the flat than other people her age. She has two children aged 8 and 10 years and they have a cat and a rabbit at home. In the respiratory system expansion of the lungs seems to be reduced but sym- metrical. It is often difficult to be sure of the exact length of history when a symptom such as breathlessness has an insidi- ous onset. There is a history of asthma but the absence of wheezing or obstruction on the respiratory function tests rule that out. An occupational history is always important in lung disease but probably not here. Occupational asthma can be associated with the printing trade but not a restrictive problem as shown here. The findings on examination fit with a restrictive problem with limited expansion and the crackles caused by re-opening of airways closing during expir- ation because of stiff lungs and low lung volumes. Further tests such as transfer factor would be expected to be reduced in the presence of pulmonary fibrosis. The chest X-ray shows small lung fields and nodular and reticular shadowing most marked in mid and lower zones. These changes are compatible with diffuse pulmonary fibrosis (fibro- sing alveolitis). In talking about fibrosis of the lungs it is important to differentiate diffuse fine pulmonary fibrosis, as in this case, and localized pulmonary fibrosis as a result of scarring after an acute inflammatory condition such as pneumonia. Diffuse pulmonary fibrosis can be associated with conditions such as rheumatoid arthritis and can be induced by inhaled dusts or ingested drugs. Further investigations consist of a search for a cause or associated conditions and a deci- sion whether a lung biopsy is warranted. Bronchoscopic biopsies are too small to be rep- resentative or useful in this situation, and a video-assisted thoracoscopic biopsy would be the usual procedure. It would usually be appropriate to obtain histology of the lung in someone of this age. There is some evidence that anti-oxidants such as acetylcysteine improve the outlook and these may be combined with the steroids and azathioprine. In a patient of this age, lung transplantation might be a consideration as the dis- ease progresses. Progression rates are variable and an acute aggressive form with death in 6 months can occur. A subendocardial inferior myocardial infarction was diagnosed and he was treated with thrombolytics and aspirin. This showed severe triple-vessel disease not suitable for stenting, and coronary artery bypass grafting was performed. He is attending a cardiac rehabilitation clinic and he has had no further angina since his surgery. He has a strong family history of ischaemic heart disease, with his father and two paternal uncles having died of myocardial infarctions in their 50 s; his 50-year-old brother has angina. He has bilateral corneal arcus, xanthelasmata around his eyes and xanthomata on his Achilles tendons. He has many clinical features to go with the high cholesterol and prema- ture vascular disease. The homo- zygous condition is rare and affected individuals usually die before the age of 20 years due to premature atherosclerosis. Corneal arcus, xanthelasmata and xanthomata on Achilles tendons and the exten- sor tendons on the dorsum of the hands develop in early adult life. The other major causes of hypercho- lesterolaemia are familial combined hyperlipidaemia and polygenic hypercholesterol- aemia.

Mangoes exerted a marked effect on the incidence of diarrhoea and smaller effect on the incidence of dysentery safe cefadroxil 250 mg. All variation in the incidence of diarrhoea between the 12 months of the year was accounted for but there remained some variation in the incidence of dysentery between the months after the effects of all other factors had been removed best 250 mg cefadroxil. Between the 4 years of the study there remained variation in the incidence of both disorder due to some factor (s) not considerd in this investigation. Despite the fact that amoebiasis has long commonded the attention of investigators throughout the world. Among the healthy Burmese (20 out of 55)36 percent had subnormal xylose absorption (10-29 per cent excretion); (3 out of 36) 8 per cent had defective vitamin A absorption with 5 hour plasma vitamin A levels less than 150 g per cent (9 out of 26) 35 per cent had defective folate absorption with 5 hour urinary excretion less than 0. Considerable variation in xylose absorption was found on repeating the test at one week intervals. Among subjects with recent diarrhoea (8 out of 41) 20 per cent had abnormal xylose absorption(less than 10 per cent excretion) and (21 out of 41) 15 per cent had subnormal xylose absorption (17 out of 30) 57 per cent had defective vitamin A absorption; (20 out of 27) 74 per cent had defective folate absorption. The incidence of defective xylose, vitamain A and folate absorption was significantly higher in those with recent diarrhoea when compared with the healthy subjects. The incidence of impaired absorption of vitamin A and folate is higher in individuals with defective xylose absorption than in those with normal xylose absorption. Apparently, improved small intestinal function exists in a considerable proportion of apparently healthy Burmese as revealed by defective xylose and to a lesser extent vitamin A and folate absorption. Also, that defective small intestinal function occurs during and up to one week after an acute episode of diarrhoea. The presence of predominatly leaf shaped jejunal villi in Burmese subjects not suffering from diarrhoea is noted. Among healthy Burmese (21 out of 55) 40% had subnormal xylose absorption (10- 20% excretion); (3 out of 36) 8% had defective vitamin A absorption with 5hr plasma vitamin A levels less than 150 g%; (9 out of 26) 35% had defective folate absorption with 5 hr 17 Bibliography of Research Findings on Gastrointestinal Diseases in Myanmar urinary excretion less than 0. Considerable variation in xylose absorption was found on repeating the test at one week s interval. Among subjects with recent diarrhea (8 out of 41) 20% had abnormal xylose absorption (less than 10% excretion) and (20 out of 41) 51% had subnormal xylose absorption; (17 out of 30) 57% had defective vitamin A absorption; and (20 out of 27) 74% had defective folate absorption. The incidence of defective xylose, vitamin A and folate absorption was significantly higher in those with recent diarrhoea when compared with the healthy subjects. The results of similar tests on the 7 subjects with diarrhoea as well as plasma protein, serum carotene, and creatinine clearance values of all the subjects are also given. It is concluded that impaired small intestinal function exists in a considerable proportion of apparently healthy Burmese as revealed by defective xylose and to a lesser extent vitamin A and folate absorption. Also, that defective small intestinal function occurs during and up to one week after an acute bout of diarrhea. The presence of predominantly leaf-shaped jejunal villi in Burmese subject not suffering from diarrhea is noted. Altogether, stools from 420 students (266 male and 154 female students) were examined using hypersaturated saline concentration method. Comparative evaluation of the treatment of ascariasis with Piperazine citrate (Burazine, B. This evaluation can be th resumed with satisfaction only when the Institute reopens on 5 January 1970. William Budd in 1856 recognised the excremental rules of typhoid and outlined the regional hygienic principles in control of epidemics. Archard isolated Salmonella typhi in1896 and in the same year Widal described Widal reaction. In the same year, the first prophylactic inoculation against typhoid was introduced. Chloramphenicol was discovered and manufactured inthe year 1947 which is still the best 18 Bibliography of Research Findings on Gastrointestinal Diseases in Myanmar availab1e drug at present in the treatment of enteric fever. The history of enteric fever in Burma dates back only in 1910, when it was discovered that the disease was prevalent among the natives. Most admissions being from districts, the high mortality of which was attributable to journey to Rangoon. At present, the cases are still on the increase and sporadic outbreaks have been reported from many parts of Burma. The morbidity of enteric fever during the period 1910-1966 shows the trends of increase. However, the case fatality ratio declined rapidly since 1949 following introduction of chloramphenicol in the treatment of enteric fever. This dissertation is based on available data concerning the epidemiological data of enteric fever in Burma.
