The toxicity of chloramphenicol in infants is due to immaturity of the glucuronide conjugating system discount gasex 100caps amex gastritis diet 666, allowing a toxic concentration to accumulate buy generic gasex on-line gastritis and duodenitis. In the presence of renal failure order gasex cheap gastritis university of maryland, drugs such as the aminoglycosides buy cheap gasex 100 caps online gastritis with fever, normally excreted by this route, may accumulate and produce toxic reactions. They are therapeutically undesirable, but often unavoidable, pharmacologic actions occurring at usual prescribed drug dosages. A drug frequently has several pharmacologic actions, and only one of those may be the desired therapeutic effect. The first-generation antihistamines commonly cause adverse central nervous system effects, such as sedation. Their anticholinergic side effects include dry mouth, blurred vision, and urinary retention. Other side effects may be delayed in expression and include teratogenicity and carcinogenicity. Methotrexate, which has been used in some steroid-dependent asthmatic patients, is teratogenic and should not be used during pregnancy. Immunosuppressive agents can alter host immunity and may predispose the patient to malignancy (17). They may be interpreted as the appearance of another naturally occurring disease rather than being associated with administration of the drug. Some appear to be due to the drug itself, creating an ecologic disturbance and permitting the overgrowth of microorganisms. In the presence of antimicrobial (notably ampicillin, clindamycin, or cephalosporins) exposure, Clostridium difficile can flourish in the gastrointestinal tract in an environment in which there is reduced bacterial competition. Toxins produced by this organism may result in the development of pseudomembranous colitis (18). Antimicrobial agents may be associated with another group of reactions that may mimic hypersensitivity, but appear to be disease associated. The reaction is believed to result from the release of microbial antigens, endotoxins, or both ( 19). This has usually followed penicillin treatment of syphilis and leptospirosis, but also has been observed during treatment of parasitic and fungal infections. With continued treatment, the reaction subsides, thus confirming it is not an allergic response. Unfortunately, treatment is often discontinued and the drug blamed for the reaction. Another example would include the high incidence of skin rash in patients with the Epstein-Barr virus treated with ampicillin. Drug Drug Interactions A drug drug interaction is generally regarded as the modification of the effect of one drug by prior or concomitant administration of another. Fortunately, drug drug interactions of major clinical consequence are relatively infrequent ( 20). It is also important to recall that not all drug interactions are harmful, and some may be used to clinical advantage. As the number of drugs taken concurrently increases, the greater the likelihood of an adverse drug interaction. When an interaction is reported, an average of between four and eight drugs are being taken by the patient. Therefore, the largest risk group are elderly patients, who often receive polypharmacy. The danger of an interaction also escalates when several physicians are treating a patient, each for a separate condition. Several widely prescribed agents used to treat allergic rhinitis and asthma interacted significantly with other drugs. The second-generation antihistamines, terfenadine and astemizole, were metabolized by cytochrome P-450 mixed-function oxidase enzymes. These antihistamines, in combination with drugs that inhibited the P-450 enzyme system, such as the imidazole antifungals ketoconazole and itraconazole or the macrolide antibiotics erythromycin and clarithromycin, resulted in increased concentrations of the antihistamines. An excellent review of other adverse drug interactions may be found in a looseleaf publication authored by Hansten and Horn ( 22). Intolerance Intolerance is a characteristic pharmacologic effect of a drug which is quantitatively increased, and often is produced, by an unusually small dose of medication. Most patients develop tinnitus after large doses of salicylates and quinine, but few experience it after a single average dose or a smaller dose than usual. This untoward effect may be genetically determined and appears to be a function of the recipient, or it may occur in individuals lying at the extremes of dose-response curves for pharmacologic effects. In contrast to intolerance, which implies a quantitatively increased pharmacologic effect occurring among susceptible individuals, idiosyncratic and allergic reactions are qualitatively aberrant and inexplicable in terms of the normal pharmacology of the drug given in usual therapeutic doses. Idiosyncratic Reactions Idiosyncrasy is a term used to describe a qualitatively abnormal, unexpected response to a drug, differing from its pharmacologic actions and thus resembling hypersensitivity. However, this reaction does not involve a proven, or even suspected, allergic mechanism. A familiar example of an idiosyncratic reaction is the hemolytic anemia occurring commonly in African and Mediterranean populations and in 10% to 13% of African American males (sex-linked) exposed to oxidant drugs or their metabolites. About 25% of African American females are carriers, and of these, only one fifth have a sufficiently severe expression of the deficiency to be clinically important. A more severe form of the deficiency occurs in Caucasian Americans, primarily among people of Mediterranean origin. Clinically, the three classes of drugs most important in terms of their hemolytic potential are sulfonamides, nitrofurans, and water-soluble vitamin K analogues.

There are however no controlled studies to determine if surgery is more beneficial than non-surgical treatment 100caps gasex free shipping gastritis kronis. Hospital-acquired or nosocomial pneumonia which have a far higher mortality rate buy 100 caps gasex amex gastritis diet öèòðóñ, are usually bacterial in origin order gasex 100caps with mastercard gastritis diet ñêà÷àòü, although viral infections can also occur generic 100 caps gasex fast delivery gastritis diet ulcer, 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. Some patients may develop renal failure and this combination of respiratory failure and renal failure has a high mortality rate. Haemophilus influenza is a Gram-negative coccobacillary rod that occurs in either a typable, encapsulated form or a nontypable, unencapsulated form. Patients present with a sudden onset of fever, sore throat, cough and pleuritic stabbing chest pain. Adult mortality rates are high and mostly reflect the impact of the coexisting illness.
Case definition Suspected case: Any person with an abrupt onset of headache cheap gasex 100caps visa gastritis with fever, chills and rapidly mounting fever generic gasex 100 caps visa gastritis y sintomas, malaise purchase 100caps gasex with visa gastritis chronic, prostration and rash cheap 100 caps gasex chronic gastritis biopsy. Visceral leishmaniasis is 125 Manual on Investigation and Management of Epidemic Prone Diseases in Ethiopia distributed throughout the low lands of Ethiopia with varying degree of endemicity. The most important foci are the Metema and Humera low lands in the north-west, the Segen valley and its surroundings in Konso (South-west) and the lower Omo plains (South-west). The north eastern part of the country along the Awash valley to the Ethio-Djiboutic border is as well potentially enedemic. The leshimaniases are parasitic diseases with a wide range of clinical symptoms: of mainly cutaneous, mucocutaneous and visceral. The leishmaniases are caused by different species of protozoan parasites belonging to the genus leishmania. Visceral leshimaniasis is characterized by irregular bouts of fever, substantial weight loss, swelling of the spleen and liver, and anemia (occasionally serious). In epidemic visceral leishmaniasis, people of all ages are susceptible except those who acquired 126 Manual on Investigation and Management of Epidemic Prone Diseases in Ethiopia immunity during a previous epidemic. Transmission: the disease is transmitted to humans by the bite of a tiny 2 to 3 millimeter-long insect vector, the phlebotomine sandfly. Risk factors: Movement of non-immune people into potential visceral leishmaniasis endemic; areas Malnutrition; Ecological change in favour of the sand fly vector. Case definition Suspected case: Any person with irregular bouts of fever, substantial weight loss, swelling of the spleen and liver, and anemia. Investigation Investigate the case to determine risk factors contributing to transmission. Specific management Treat the confirmed cases with sodium stibogluconate or other available effective alternative drugs. Transmission: transmitted human-to-human via the bite of aedes mosquitoes (urban epidemic) or via forest mosquito species and forest primate reservoir (jungle cycle). Determinants: Sporadic cases often linked to occupation or village location near woods or where monkeys are numerous. Case definition Suspected case: A person with acute onset of fever followed by jaundice within two weeks of onset of first symptoms. Confirmed case: A suspected case with laboratory confirmation (positive IgM and viral isolation) or epidemiologic link to confirmed cases or epidemics. Investigation Collect specimen for laboratory confirmation Investigate the case to determine how transmission occurred. Improve routine and mass vaccination campaigns to include yellow fever in high risk areas. Today, there is no vaccine for preventing the infection and also it is unclear that if antiviral medications that are commonly used for influenza are effective. Definition: Avian Influenza /fowl plague/ bird flu / is a zoonotic viral disease that affect chickens, turkeys, other wild birds and human being. The past experience indicates that there is no regularity to pandemics and no reliable basis for predicting when/where that might arise. The most recent cause for concern occurred in December 2003 that confirmed the cause of pandemic was H5N1(type of virus with high pathogenic characteristics) avian influenza virus in human ( Vietnam). In Ethiopia, the influenza epidemic known as the Hedar Basheta and also there were two distinct epidemic waves in 1918. Transmission: The way of spread to Human:- Touching an infected bird, fluids or surfaces contaminated with fluids from infected birds Close contact with live or improperly cooked poultry Exposure during slaughter and preparation of domestic poultry for cooking Contact with dead wild birds or their parts Wild bird migration Animal and human populations in close proximity (farm animals and pets in/under/next to houses, live 136 Manual on Investigation and Management of Epidemic Prone Diseases in Ethiopia animal markets (many species from many countries) Poor agricultural practices (inadequate infection control on farms, poultry excrement used in agriculture e. Investigation Case Definition Specimen Collection Case Finding Interviewing Contact Identification Reporting Data Management Creating an Epidemic Curve Assessing Transmission Writing a Summary Report c. Epidemic in school settings Dealing with epidemic outbreaks is one of the difficult challenges facing school health. Though the general principles of epidemic investigation and control hold also true for outbreaks in schools or campuses, there are some points that deserve especial consideration and further discussion. The speeds with which disease occurrences need to be reported are very much dependent on the incidence/prevalence of the disease and the action that needs to be taken to address it. The school health team and representatives from administration should contact the Public Health Authority of the locality in order to control the epidemic. An investigation should be started to determine the cause and measures to contain the epidemic and prevent a reoccurrence should be taken. Information gathered will come from laboratory testing of specimens, interviewing both those who are cases and those who are not cases and from onsite assessments of the environment. Control measures to eliminate or reduce the spread of the illness should be implemented at once for example administering preventive therapy such as vaccination, measures targeted at water and food supplies in the school. However, it is recommended that infectious disease surveillance in school children should be part of 147 Manual on Investigation and Management of Epidemic Prone Diseases in Ethiopia national communicable disease surveillance system. In conducting active surveillance, involving students like class representatives is proven effective in epidemic preparedness and management. The outbreak should be discussed thoroughly with experts from the Health Department of the local government, and the public should be reassured. Forming an ad hoc committee composed of parents to monitor and discuss evaluation of the procedures is important in order to make sure that procedures are carefully followed and if mistakes have been made, performance can be improved. This may involve things such as policy and procedure changes, ongoing education programs, environmental changes, etc. Prisoners usually return to society after serving their sentence, or earlier because of pardons or amnesties. However, there is often little collaboration between detaining authorities and the civilian sectors 149 Manual on Investigation and Management of Epidemic Prone Diseases in Ethiopia responsible for health care delivery or social welfare; this remains a serious challenge in prison health. In addition to a weak collaboration, another problem is the steady rise in prison populations throughout the world despite efforts for penal reform and the use of alternative punishment systems.
