It issues recommendations for vaccines that are used by health care providers in both public and private sys tems. They come from a broad array of institutions across the country, including academia, hospitals, public health and government institutions. In addition to the public health and infectious administration to the Minister for diseases experts on the committee, the committee includes Health and Ageing membership from consumer groups, general practitioners, and nursing representatives38. These committees provide tional and optional vaccines in addition to the basic pediatric advice to the ministry of health. In other countries, national advisory commit Countries that do not have a national advisory committee of tees recommend vaccines, but local health authorities determine experts, or that are not advised by national medical associa which specifc products they wish to utilize. Most industrialized countries strongly value immunization as a cost-effective means to prevent disease and save on treatment costs, and as a means to preserve economic development. Immunization is also valued by some industrial ized countries as an asset against bioterrorism. Like many other complex and capital intensive industries, the vaccine industry in highly consolidated. The vaccine market is dominated by a few large vaccine suppliers in industrialized countries. The costs associated with developing new vaccines require that vaccines be sold on the global market in order to be able to recoup R&D investments. Furthermore, almost all coun tries import at least some vaccines because not all national suppliers produce every antigen available. Vaccine research and development has largely been restricted to the few vaccine producing countries. Vaccine devel Assay development: to develop the appropriate tests to ascer opment is highly capital intensive and risky. Given the importance tain the purity, potency and stability of the vaccine under devel of safety with biologics, the vaccine industry is highly regulated. The high failure Process development is further divided into bulk manufacturing rate is due to the unpredictability of the biological microorgan and product fnishing. Bulk manufacturing involves the culture of isms needed to produce vaccines, and to the uncertainty of how live microorganisms, followed by separation and purifcation of the human immune system will process and react to the vaccine the desired antigen. Some vaccine candidates may produce appropriate lev adjuvant and/or stabilizer and the flling of vials or syringes. Other vaccine candidates may be safe, but ineffective at pre Clinical development, as described earlier, involves the iterative venting diseases. With the current tendency to combine several process of testing a vaccine candidate in a progressively larger antigens into a single vaccine, the challenges associated with number of human subjects. Assay development is required because the vaccine candidate Research to discover new vaccine antigens and novel approaches will be novel and will therefore require specifc tests to identify it to immunization usually takes several years, and costs tens of and characterize the product to the satisfaction of the regulators. Once a discovery is made, several develop ments must be undertaken to reach the licensing stage. Only vaccine can didates that are determined to be safe and capable of inducing an immune response advance to a next phase (See Figure 15, Section 1.

Some of these may be danger living microorganism used in the vaccine; ous human pathogens. Therefore, the manufacture of vaccines is conducted in a highly regulated and controlled environment. It may also include the addition of preservatives to some vaccines, to ensure the sterility Manufacturing is conducted in an aseptic environment and closely of the product over a longer period of time, or to prevent cross monitored by quality control measures. At the end of the manufacturing process, vaccines are typically flled in vials or syringes and packaged for shipping to health the actual production processes vary somewhat for different care providers. Some components of the manufacturing pro cess are specifc to either viral or bacterial vaccine production. Manufacturers must, therefore, carefully characterize and store the master seed viruses or bacteria used to start each production run. In general, the production of vaccines entails four basic steps (See figure 36): Propagation Isolation Purification Formulation fIgUrE 36. After propagation, isolation may be conducted by has been propagated, it must then be isolated from the cells centrifugation or specifc polysaccharide extraction techniques. This may be achieved by several Purifcation is specifc to the antigen, but may include chemical techniques including chemical lyses of the cell, centrifugation precipitation or fractionation, or ultra-fltration and chromatog and fltration, or homogenization. At this stage, carrier proteins may be conjugated to some polysaccharide vaccines and the conjugate vaccine is the next step, purifying the virus, may likewise involve multi then purifed by various fltration or chromatography techniques. Some vaccines are freeze-dried (lyophilized) at this stage, to prolong their shelf-life. A manufac last half century (See Image turing facility alone will cost 4, Image 5, Image 6)57.

Symptoms Kidney stones usually cause severe pain in their attempt to pass down the ureter on their way to the bladder acne einstein generic 15gr differin mastercard. Other symptoms of kidney stones are a desire to urinate frequently skin care ingredients order differin with a mastercard, painful urination acne off generic 15 gr differin overnight delivery, scanty urination acne complex buy differin, nausea, vomiting, sweating, chills and shocks. Sometimes, large stones may remain in the kidneys without causing any trouble and these are known as silent stones. Causes the formation of stones in the kidneys is the result of defects in the general metabolism. They usually occur when the urine becomes highly concentrated due to heavy perspiration or insufficient intake of fluids. The other causes are wrong diet, excess intake of acid-forming foods, white flour and sugar products, meat, tea, coffee, condiments and spices, rich foods and overeating. Lack of vitamin A and an excessive intake of vitamin B may also lead to formation of stones. Types of Stones Chemically, urinary stones are of two categories, namely, primary stones and secondary stones. Primary stones are ordinarily not due to infection and are formed in acidic urine. They usually result from alcoholism, sedentary life, constipation and excessive intake of nitrogeneous or purine-rich foods. Most kidney stones are composed either of calcium oxalate or phosphate, the latter being most common in the presence of infection. More than half of these are mixtures of calcium, ammonia, and magnesium, phosphates and carbonates, while the remainder contain oxalate. Uric acid and cystine stones represent about four percent and one per cent respectively of the total incidence of stones. Treatment A majority of patients suffering from kidney stones can be treated successfully by proper dietary regulations. The patient should avoid foods which irritate the kidneys, to control acidity or alkalinity of the urine and to ensure adequate intake of fluids to prevent the urine from becoming concentrated. The foods considered irritants to the kidneys are alcoholic beverages, condiments, pickles, certain vegetables like cucumbers, raddishes, tomatoes, spinach, rhubarb, water-cress and those with strong aroma such as asparagus, onions, beans,cabbage and cauliflower, meat, gravies and carbonated waters. An abnormally high intake of milk, alkalies or vitamin D may also result in the formation of calcium phosphate stones. For controlling the formation of calcium phosphate stones, a moderately low calcium and phosphorous diet should be taken the intake of calcium and phosphates should be restricted to minimal levels consistent with maintaining nutritional adequacy. In this diet, milk should constitute the main source of calcium and curd or cottage cheese, lentils and groundnuts should form the main sources of phosphorous. Foods which should be avoided are whole wheat flour, Bengal gram, peas, soyabeans, beets, spinach, cauliflower, turnips, carrots, almonds and coconuts. When stones are composed of calcium and magnesium phosphates and carbonates, the diet should be so regulated as to maintain acidic urine. Insuch a diet, only half a litre of milk, two servings of fruits and two servings of vegetables (200 grams) should be taken. The vegetables may consist of asparagus, fresh green peas, squash,pumpkins, turnips, cauliflower, cabbage and tomatoes. For fruits, watermelon, grapes, peaches, pears, pineapple, papayas and guavas may be taken. On the other hand the urine should be kept alkaline if oxalate and uric acid stones are being formed. In this diet, fruits and vegetables should be liberally used and acid-forming foods should be kept to the minimum necessary for satisfactory nutrition. When the stones contain oxalate, foods with high oxalic acid content should be avoided. These foods include almonds, beetroots, brinjal, brown bread, cabbage, cherry, chocolate, French Beans, potatoes, radish, spinach and soyabeans. Uric stones occur in patients who have an increased uric acid in the blood and increased uric acid exertion in the urine. Since uric acid is an end product of purine metabolism, foods with a high purine content such as sweet bread, liver and kidney should be avoided. Kidney beans, also known as French beans or common beans, are regarded as a very effective remedy for kidney problems, including kidney stones. Ramm of Germany, who first discovered the value of kidney beans as a medicine for kidney and bladder troubles. The method prescribed by him to prepare the medicine is to remove the beans inside the pods, then slice the pods and put about 60 mg. This liquid should be strained through fine muslin and then allowed to cool for about eight hours. Thereafter, the fluid should be poured through another piece of muslin without stirring. Ramm, a glassful of this decoction should be given to the patient every two hours through the day for one day, and thereafter it may be taken several times a week. The pods can be kept for longer periods but once they are boiled, the therapeutic factor disappears after one day. The basil, known as tulsi inthe vernacular, has a strengthening effect on the kidneys. It has been found that the stones can be expelled from the urinary tract with this treatment. The celery is also a valuable food for those who are prone to stone formation in the kidneys or the gall bladder. Research has shown the remarkable therapeutic success of vitamin B6 or pyridoxine in the treatment of kidney stones. This treatment has to be continued for several months for obtaining a permanent cure. The patient should take a low protein diet, restricting protein to one gram per kg. The patient should be given a large hot enema, followed by a hot bath with a temperature of 100 o F, gradually increased to 112 o F. Hot fomentation applied across the back in the region of the kidneys will relieve the pain. Certain yogasanas such as pavan-muktasana, uttanpadasana, bhujangasana, dhanursana and halasana are also highly beneficial as they stimulate the kidneys. There isa gradual loss of pigment melanin from the skin layers which results in white patches. It, however, brings about great psychological tension to the patient who is more embarassed than the victim of any pain or discomfort. The condition thus, besides being a medical problem, also becomes a social stigma. The most affected areas are the hands, the neck, the back and the wrist in that order. Symptoms the problem usually starts with a small white spot and later on it develops into patches. These patches are pale in the beginning but become whiter and whiter as time passes due to loss of pigment. As spots enlarge, they merge into each other and, in course of time, form a very broad patch. It is not caused by eating fish and drinking milk at the same time, as is generally believed because even vegetarians suffer from this disorder. Other food combinations such as pumpkin and milk, onion and milk as possible causes of leucoderma also have no basis. The main causes of leucoderma are excessive mental worry, chronic or acute gastric disorder, impaired hepatic function such as jaundice, worms or other parasites in the alimentary canal, ailments like typhoid which affect the gastrointestinalm tract, defective perspirative mechanism and burn injuries. Heredity is also a causative factor and about 30 per cent of patients have a family history of the disorder. Treatment In nature cure, the treatment of leudoderma consists of adoption of constitutional measures to cleanse the system of accumulated toxins.

Analyze, Communicate, and Act 31 32 Risk-Based Post-Marketing Quality Surveillance Measuring Post-Marketing 06 Surveillance Capacity Post-marketing surveillance capacity varies from one country to another, and the effectiveness of these programs depends on many interconnected factors. In building post-marketing surveillance capacity, it is important to consider the existing available legal provisions; infrastructure; systems; governance; roles and responsibilities of each stakeholder; and human resource skills, expertise, and ability to utilize available tools 19. Due to these complexities, measuring the post-marketing surveillance capacity of a country (as described in Figure 5) can be difficult. Systematic capacity building in hierarchical needs (adapted from Potter and Brough) It is also important to consider establishing a consensus-based set of indicators among the key stakeholders. Examples of consensus metrics applicable to a distributor company Quality metrics Description/definition indicator Product quality Number of quality complaints / Number of units released complaint rate. It is worth noting that these indicators cannot be collected and measured if a regulatory authority does not possess the appropriate infrastructure and human and financial resources and if the inspectorate does not take responsibility for the post-marketing surveillance program. Using well-designed and selected indicators enables decision-makers to assess whether or not progress is being made toward expected outputs, outcomes, objectives, and 21 goals. In other words, the indicators should measure the existence and performance of key post-marketing surveillance structures and processes; identify the strengths and weaknesses; and reveal achievements, growth, or lack thereof. Indicators should also measure the degree to which strategic objectives and activities bring about results. Developing standardized indicators can support the collection of standardized data to measure capacity. To calculate indicators, data are needed about the specific post-marketing surveillance program. These data should be available within the regulatory information management system. Measurable Post-marketing surveillance indicators should be able to evaluate the baseline situation (structure, systems, infrastructure, tools, and human resource capacity), track progress made during a specific period of time, and support the assessment of services and interventions. Structural indicators assess the existence of key post-marketing surveillance structures, programs, and mechanisms in the environment being measured. They also assess the existence of basic infrastructure, policy, and a regulatory framework required for enabling post-marketing surveillance operations. Process/ Measure the resources needed for the implementation of an activity or intervention Input and may include policies, human resources, materials, and financial resources. Examples include meetings held, training courses conducted, medicines distributed, and materials developed. For example, the output of a training course on sampling and testing of pharmaceutical products may be the number of officers trained and, consequently, the number or proportion with improved knowledge/skills in sampling and testing. Outcome indicators are used to demonstrate the degree to which post-marketing surveillance objectives are being met. Impact Measure the extent to which post-marketing surveillance program objectives contribute to safeguarding the public from harmful medicines. Measuring these indicators can be difficult due to multiple factors, interventions, and externalities that also affect impact. Data collection methods and techniques Data should be collected using pre-defined indicators; a proposed list is provided (see Table 9). A combination of techniques should be used to collect data, including the following: 1. Field inspection: To collect data, including pharmaceutical product samples for quality testing as appropriate, to gain information on supply and distribution chains. Existing post-marketing surveillance data: For countries with a medicines quality monitoring program in place, quantitative data on samples and test results from field operations can also be considered, and these data should be obtained. Measuring Post-Marketing Surveillance Capacity 35 Methods for data analysis, reporting, and data presentation Both qualitative and quantitative data collected for each indicator should be examined, analyzed, and (where appropriate) computed into percentages by the appropriate personnel under the supervision of a qualified officer. Where necessary and appropriate, these data should be presented in tables or other graphic depictions for better visual data comparisons among various geographical areas in the country. In the analysis, both the number and proportion (numerator/denominator) expressed as a percentage (%) should be used for selected indicators. Most indicators are expressed in numbers to explicitly reflect the actual data, which may not provide a true picture if expressed as a percentage. The percentage also does not indicate whether the recall occurred in a 1-, 2-, or 3-year period. Breakdown of the numbers and % of product recalled by year for Company Z N = products distributed n= products recalled % Total 300 9 3. These data prompt the post-marketing surveillance inspectorate to include Company Z on the list of at-risk establishments, which warrant closer scrutiny for at least 2 to 3 years.

While a 120 mg/day dose was shown to be effective, there is no evidence that doses greater than 60 mg/day confer any additional benefits. Periodically reassess to determine the need for maintenance treatment and the appropriate dosage for such treatment. While a 120 mg once daily dosage was shown to be effective, there is no evidence that doses greater than 60 mg/day confer additional benefit. Nevertheless, if a decision is made to increase the dosage beyond 60 mg once daily, increase dosage in increments of 30 mg once daily. Periodically reassess to determine the continued need for maintenance treatment and the appropriate dosage for such treatment. If a decision is made to increase the dose beyond 60 mg once daily, increase dose in increments of 30 mg once daily.
The following treatment recommendations for children of 5 years of age or younger are based on the available evidence and on expert opinion skin care chanel cheap differin online amex. Although the evidence is expanding it is still rather limited as most clinical trials in this age group have not characterized participants with respect to their symptom pattern acne types best buy for differin, and different studies have used different outcomes and different definitions of exacerbations skin care products order differin amex. Generally skin care zits generic differin 15 gr with visa, treatment includes the daily, long-term use of controller medications to keep asthma well-controlled, and reliever medications for as-needed symptom relief. Intermittent or episodic wheezing of any severity may represent an isolated viral-induced wheezing episode, an episode of seasonal or allergen-induced asthma, or unrecognized uncontrolled asthma. Further treatment of the acute wheezing episodes themselves is described below (see Acute asthma exacerbations in children 5 years and younger, p. However, uncertainty surrounds the addition of other drugs in these children, especially when the nature of the episode is unclear. If good asthma control is not achieved with a given therapy, trials of the alternative Step 2 therapies are recommended prior to moving to Step 3. The child should be referred for expert assessment if symptom control remains poor and/or flare-ups persist, or if side effects of treatment are observed or suspected. The relative cost of different treatment options in some countries may be relevant to controller choices for children. In addition, reassess and address control of environmental factors where relevant, and reconsider the asthma diagnosis. Benefits, and risks of side effects, should be considered, as described previously. The need for additional controller treatment should be re-evaluated at each visit and maintained for as short a period as possible, taking into account potential risks and benefits. The doses listed here are the lowest approved doses for which safety and effectiveness have been adequately studied in this age group. Higher doses are associated with an increased risk of local and systemic side-effects, which must be balanced against potential benefits. Asthma-like symptoms remit in a substantial proportion of children of 5 years or younger,675-677 so the need for continued controller treatment should be regularly assessed. Marked seasonal variations may be seen in symptoms and exacerbations in this age-group. For children with seasonal symptoms whose daily long-term controller treatment is to be discontinued. Multiple actuations into the spacer before inhalation may markedly reduce the amount of drug inhaled. Crucial to a successful asthma education program are a partnership between patient/carer and health care providers, with a high level of agreement regarding the goals of treatment for the child, and intensive follow-up (Evidence D). Action plans, developed through collaboration between an asthma educator, the health care provider and the family, have been shown to be of value in older children,679 although they have not been extensively studied in children of 5 years and younger. Details of treatments that can be initiated at home are provided in the following section, Part C: Management of worsening asthma and exacerbations in children 5 years and younger, p. If there is failure of resolution, or relapse of symptoms with dexamethasone, consideration should be given to switching to prednisolone. Arrange follow up within 1 week of an exacerbation to plan ongoing asthma management. This combination predicted around 70% of exacerbations, with a low false positive rate of 14%. In contrast, no individual symptom was predictive of an imminent asthma exacerbation. In a randomized controlled trial of acetaminophen versus ibuprofen, given for pain or fever in children with mild persistent asthma, there was no evidence of a difference in the subsequent risk of flare-ups or poor symptom control. Primary care management of acute asthma or wheezing in children 5 years and younger 6. In addition, early medical attention should be sought for children with a history of severe life-threatening exacerbations, and those less than 2 years of age as the risk of dehydration and respiratory fatigue is increased (Box 6-10, p. Nebulized isotonic magnesium sulfate may be considered as an adjuvant to standard treatment with nebulized salbutamol and ipratropium in the first hour of treatment for children 2 years old with acute severe asthma. Diagnosis and management of asthma in children 5 years and younger 159 the emergency department, or, if at home, should be observed by the family/carer and have ready access to emergency care. The child should be closely monitored, and the dose should be adjusted according to clinical improvement and side effects. This approach should be reserved mainly for individual cases, and should always involve regular follow up and monitoring of adverse effects (Evidence D). Discharge and follow up after an exacerbation Before discharge, the condition of the child should be stable. Children who have recently had an asthma exacerbation are at risk of further exacerbations and require follow up. The most important of these interactions may occur in early life and even in utero. Multiple environmental factors, both biological and sociological, may be important in the development of asthma. Additional information about factors contributing to the development of asthma, including occupational asthma, is found in Appendix Chapter 2. However, a recent study of a pre-birth cohort observed that maternal intake of foods commonly considered allergenic (peanut and milk) was associated with a decrease in allergy and asthma in the offspring. High gestational weight gain was associated with higher odds of ever asthma or wheeze. Primary prevention of asthma Breastfeeding Despite the existence of many studies reporting a beneficial effect of breastfeeding on asthma prevention, results are conflicting,432 and caution should be taken in advising families that breastfeeding will prevent asthma. Regardless of its effect on development of asthma, breastfeeding should be encouraged for all of its other positive benefits (Evidence A). Timing of introduction of solids Beginning in the 1990s, many national pediatric agencies and societies recommended delay of introduction of solid food, especially for children at a high risk for developing allergy.
