There are different models of Medical Services (in-house discount zenegra 100mg free shipping, outsourced generic zenegra 100mg otc, hybrid discount 100mg zenegra, etc purchase zenegra online now. The level of service will be influenced by many factors such as size of the airline, the type of operations, the type of labour force, the culture, the labour laws, the availability and cost of the services, etc. For instance, an airline that has its own maintenance department may need a stronger occupational health expertise. However, regardless of the size of the airline, the role and responsibility of the airline medical services must be clearly defined by the airline chief executive and a clear operating plan laid out with core objectives and responsibilities. The Medical Services, like any other airline department must function efficiently, providing a cost effective service. The Medical Services also need to have a reporting line such that medical issues that may affect either passengers or employees are brought to the attention of the most senior airline staff without delay and these are recognised and evaluated quickly so prompt action can be taken. Some airlines are prepared to subsidise their medical departments, allowing them to provide the required services at a loss, but many insist on strict budgetary controls. Some Medical Services operate very effectively on a system of costing and charging other areas of their company for their services. This might seem unduly bureaucratic, but it can show most clearly to other departments within the organisation the value of the Medical Services and the costs relative to external providers. Within these domains it may provide any or all of the following functions: - Passenger health - Occupational health - Aircrew health and medical certification - Alcohol and other drugs programs - Health and wellbeing promotion - Health strategy and risk management - Primary care service 1 Medical Manual 1. Advisory service for passenger health standards, policy and procedures, and strategic matters In this area, the issue of passengers with reduced mobility requires particular attention as many States have specific regulations on this matter. In addition to setting standards, policy and procedures, the Medical Services can address passengers’ real or perceived concerns about their flight directly, or indirectly through travel agents or the airlines’ sales agents. The use of pamphlets at points of sales, and in ticket wallets, airline internet sites and in-flight magazines are all useful vehicles to provide important health information and advice for passengers and their medical advisors. This function insures that the traveling ill passenger meet established standards and policy, and will minimize the chance of deterioration in-flight. Investigation and review of data for inflight medical events including medical diversions, resuscitations and deaths with advice on remedial actions or system improvements. Inflight medical events and provision of inflight medical care received frequent media attention. The Medical Services can provide a balanced scientifically based view, keeping abreast of medical research, using proven medical data which is made widely available to all. Advisory service for public health outbreaks of airline significance and medical business issues. In this context, it is strongly recommended that the airline maintain good and regular contact with the local and national public health authorities and align each other’s emergency response plan for public health emergencies. Among other things, this relationship is very profitable for both parties to deal with contact tracing when required. The Occupational Medicine service provides specialist medical advice that augments and integrates an Occupational Rehabilitation Service. Specialist advice on standards, policies and procedures involving fitness for duty In order to protect its employees and comply with local laws, the company needs policies and processes for medical assessments such as pre-employment/pre-placement assessments, functional capacity assessments and confined space assessments. The importance of pre-employment/pre-placement assessments cannot be over emphasised. A proper pre-employment/pre-placement medical assessment may avoid many problems including serious medico-legal issues later on. The examining health professional must be aware of the physical and mental components of specific jobs and the possible hazards of the environment in which the applicant will be required to work. The assessment should focus on the safety of the applicant and others, and on the airline’s duty of care. Any relevant past medical history needs to be carefully checked and assessed for its potential impact on future employment in the airline. The pre-employment/pre-placement assessment provides the base information for the employee’s occupational health record. Failure to have such at the pre-employment stage can result later in significant and serious implications for the airline if the employee alleges an illness/injury or condition is the direct result of their employment. A declaration such as follows, gives a reasonable degree of safety to both parties: 3 Medical Manual “I hereby declare that the answers to the above questions are correct and that I have not withheld any relevant information or made any misleading statements in relation to any medical condition experienced by me either in the past or at present. In order to ensure safety and for various operational reasons, we require you to complete this form in good faith and to make a full and frank disclosure of your medical history. Your employment, and continued employment, by the Company is conditional on your having provided us with complete details of your medical history and existing medical conditions. In the event that you fail to disclose any medical condition, such failure will entitle the company, at its discretion, to withdraw your offer of employment or to terminate your contract of employment, whichever is appropriate. In addition, failure to disclose medical conditions may, in certain circumstances, invalidate insurance policies such as medical insurance and life and personal accident insurance, provided to you by the Company. This is driven by their own requirements, local labour laws and where staff is recruited from. In many airlines a simple health questionnaire plus declaration is all that is required, others, depending on the type of job, require more details, for example, flight deck crew, cabin crew, engineering staff. Some airlines provide very specific additional protocols depending on the job applied for, which concentrate on gathering information about the individual’s medical status in relation to that function. Additional biometric testing may be required such as audiometry and visual acuity for those working in the noisy airside areas. The Medical Services can also provide advices on first aid and medical emergency procedures for employees including any workplace defibrillator access program. Depending on the size of the base, the number of working employees, and the local medical facilities available in the community, an in-house medical service can sometimes provide the first aid and emergency response itself. Such a service can also consider functioning as a poison control centre, maintaining a list of all possible toxic substances and their antidotes. Similarly, a roster of centres for the treatment of the severely burned patient should be readily available. Airlines operate globally to destinations all over the world where health standards and endemic disease patterns vary greatly. It is essential that all airline staff who travel are protected against the common endemic diseases by immunisation and malaria prophylaxis as appropriate. This applies to all aircrew, and also engineers, maintenance staff, management staff, and all others who undertake duty travel. Airline staff should carry their vaccination records and ensure that they are kept current. Health Authorities at many airports may demand to inspect these documents and difficulties can arise if crew vaccination records are found to be invalid. In some countries passengers may contact airline Medical Services for advice about immunisation requirements and needs at destinations. Therefore, it is necessary for the airline to be able to provide up-to-date and accurate information on the varying immunisation requirements and recommendations worldwide. This is best provided through Travel Clinics or via the many excellent websites now available 4 Role and Responsibilities of an Airline Medical Department Airlines usually employ many safety sensitive employees. Special attention is required for these employees’ illnesses and safe use of medication. Specialist advice on mitigating the risks to health from work Any responsible company wishes to prevent occupation injuries and illnesses. The wide spectrum of occupational groups in the aviation industry provides a substantial challenge to the airline Medical Services. The relationship between the work environment and the health status of airline employees is complex and variable and requires a full risk assessment of every job and its component parts. The potential hazards include noise, the use of solvents, paint stripper, toxic metals, isocyanates and radiation among other things. A hearing conservation policy and process, as well as a health surveillance and biological monitoring policy and process are needed. Assessment of workplace illumination, ventilation, seating and other ergonomic factors are also essential. The Medical Services can also work with the Safety Department (if the two services are separate) to establish in injury prevention program. Periodic health assessments provide an opportunity for the employee to discuss health matters with someone who knows about his/her particular job. In addition, periodic assessments may provide the physician with an opportunity to make an early diagnosis of certain conditions so that corrective steps can be taken in the pre-clinical stage of the condition.

Here they excyst (they loose the coat layer) and change to vegetative forms capable of reproduction purchase 100mg zenegra otc. The size and the shape of protozoas buy zenegra online now, and the presence of accessory organelles (flagellum or cilia) are very diverse and specific for species (it will be mentioned during the description of different parasites) purchase 100 mg zenegra with visa. According to the place of parasiting order zenegra with american express, the protozoa are divided into such of them, that can parasite in cavities, intestine and blood and tissue. The localisation of their effect is connected with their demands on the optimal life conditions and the way of their transmition. The knowledge about the place of parasiting has a major importance for their practical diagnostics. For the majority of parasitic protozoas, microscopic diagnostics is used: • native sample, eq. Other methods of diagnostics are: • cultivation evidence doesn’t have such a huge importance in protozoas as in bacteria. Cultivation on living soils (for instance amoebas or trichonomas) or tissue cultures (toxoplasmas) is possible, but is only done in specialized laboratories. The motive is often to determine the strains resistant to commonly used drugs and finding the right form of therapy in vitro; • immunological evidence (the examination of specific antibodies against parasite antigens), it is useful not only when a microscopic examination fails. Besides the evidence of the infection, it is also useful in the determination of the stage and dynamics of the disease; • molecular-genetic examinations are at the present time gaining importance. After a 10 day incubation period a vaginal effluence appears containing many trichomonas. In men the disease usually has a more latent course; only in a few per cents of cases it induces non-specific urethritis. Trichonomas is the largest flagellate which parasites in the body of the human (Fig. On its front part are four flagellas, the fifth one is connected to the body and forms an undulatory membrane. Living parasites have a typically circular motion, by which they can be easily detected in a native sample from a vaginal effluence. Amongst typical clinical manifestations are disenteric diarrheas with pain and blood in stool. Life threatening complications may arise in the case the amoebas infiltrate the different organs of the body. The cysts are resistant with the excrements they enter the external environment, foodstuff, and drinking water etc. The infection of a human therefore takes place by the so called fecal-oral way (“dirty hands disease”). The cysts resist the digestion in the stomach and excyst first in the small intestine. The vacant amoebas move around and gain food with the help of the pseudopodia (Fig. They live in the large intestine, either as forma minuta or they infiltrate the mucosa of the large intestine and change into a dysenteric magna form. This disease is infrequent in temperate climates; however in the tropical area amoebiasis is very common. The disease is spread with the help of cysts, which leave the body with the stool. Cysts have an average size of 12 x 6 µm and a typical structure; however they are not suitable for diagnostics, since they are excreted in small amounts. Vegetative forms (trophozoites) of a parasite have a typical shape simulating 37 a double sided symmetry with dimensions 10 x 7 µm. On their ventral side they have a sucking disc, by which they attach to the mucosa of the intestine. Life cycle of Giardia intestinalis The diagnostics of giardiasis is most commonly done by a microscopic examination of the duodenal juice, in which trophozoites can be found. This is because the parasites, as a film, lay out the surface of the mucosa of the small intestine, especially the duodenum. The change of chemism in this environment prevents the effects of bile and consequently cause the malabsorbtion syndrome – patient is hungry, uneasy and have bigger amount of fatty stool. A representative of these parasites in temperate climate conditions is Toxoplasma gondii. Infestation in population of central Europe is around 20 to 80% - in regard to nutrient habits, so it is a relatively frequent infection. In most cases of infected individuals Toxoplasma gondii doesn’t clinically manifest itself, since they are avirulent phyla. Only seldom, a virulent phylum, which causes an inflammation in the organ which was settled down by the parasite appears. In the past, acute taxoplasmosis accounted for less then one per mille of diseases. At present it is gaining an increasing importance as an opportunistic infection in patients with immunodeficiency. They are pathogenic and adaptive to such a degree, that they are able to multiply also in cells of macrophages and neutrophile leukocytes, which phagocyte them. The second form are avirulent bradyzoites, which assemble to several groups and form huge, so called tissue cysts, of sizes to 300 µm (Fig. If a damage of the immunocompetence of the organism occurs, the bradyzoites change the virulence, and they become tachyzoites and cause an acute inflammation. Even tough the parasite was discovered in 1908, until 1969 it wasn’t its life cycle described (Fig. Cat is classified as the definitive host, since the sexual reproduction of the parasite takes place in its intestine. The result of this is the formation of oocysts, which leave the body with the stool. In the outer environment they mature (sporulate) within 24 hours, and become very resistant. Tissue cyst Toxoplasma gondii If any kind of warm-blooded animal swallows the oocyst, it excysts in its intestine and releases 8 tachyzoites. It was experimentally proven, that small animals, for example rodents, have a slower reaction time after the infection by toxoplasmas. For cats this makes their hunting easier, but also allows the infection of the cat by toxoplasmas. The particularity of Toxoplasma gondii is that it can be passed from human to human, to be more exact the transplacental transfer – from the mother to the fetus etc. The condition for this is the primo-infection of the mother by a sufficiently virulent phylus. It was found out that the probability of infection of the fetus increases with the length of gravidity. Typical congenital toxoplasmosis is rare and manifests itself especially by brain damage (hydrocephalus) caused by the infection. More common are late side-effects of prenatal infection by toxomplasmas, as the typical affliction of the retina (coloboma). Scheme of the life cycle of Toxoplasma gondii 39 Plasmodia are globally one of the most spread blood and tissue parasites. It is estimated that malaria, the diseases they cause, effects about 20% of the world population. Every year more then 300 million new cases are reported, from which more then a million are fatal. In Sub-Saharan Africa, 3000 children younger then 5 years of age die everyday as a consequence of malaria. There are four types of parasiting plasmodia among humans –– Plasmodium malariae, ovale, falciparum and vivax. Each one of them causes a different type of malaria, their diagnostics is based on the recognition of the specific morphological sings of schizonts, merozoites and gemeotocytes during the examination of a microscopic sample from blood. The definite host, in which the sexual reproduction of the parasite occurs is the vector (carrier of the parasites) – the female mosquito of the Anopheles species. Parasites asexually reproduce in the erythrocytes of the intermediate hosts, in this case, infected people. First phase of the cycle takes place in the stomach of the female mosquito, that sucked the blood of the sick person.
