THE IDEAS OF PROPHYLAXIS

IN SCIENTIFIC WORKSThe main task of a doctor is about care of healthy people so that they don’t fall in disease.

Hippocrates (IV century B.C.)

The primary task of a doctor lies in preventing a disease; if you have failed to manage it – treat it; if the disease is incurable – alleviate suffering.

Botkin S.P. (1867)

I believe in hygiene. This is where real progress of our science lies. The future belongs to preventive medicine.

Pirogov M.P. (1887)

THE IDEAS OF PROPHYLAXIS

IN SCIENTIFIC WORKSA doctor must not only treat patients, but also prevent diseases; that is the ideal side of his mission; it`s the best and the most useful side of his activity.

Erismann F.F. (1887)

The more experienced the practical physician is the better he understands the omnipotence of hygiene and relative weakness of curative medicine. Only hygiene can win the dispute with the disease.

Zakharyin G.A. (1910)

PROPHYLAXIS

Prophylaxis comprises a wide network of state, medical and public measures aimed at protecting and improving people’s health, bringing up healthy young population, improving human working ability and active longevity.

Prophylaxis

Social (public)

Provided for State measures

established in the Constitution (the

right to work, housing, study etc.)

Individual (personal)

Fighting nervous, vascular, endocrine and other systems overloading of an

individual

Prophylaxis

Primary

Prophylactic technologies for disease prevention by removing risk factors (causes and

conditions of disease development) and

improving body resistance to risk factors

Secondary

Medico-prophylactic technologies for

revealing disease, preventing its progress,

aggravation and possible complications

Tertiary

Medico-prophylactic technologies aimed at

removing negative consequences of the

disease (relapses, complications,

temporary or permanent disability, death)

HYGIENE(basic) H Y G І E N E is a branch of medical knowledge, a science dealing with protecting and consolidating social (collective) and personal (individual) health by means of prophylactic measures.

H Y G І E N E is a branch of medicine, a science that studies laws of environmetal and its interaction on human organism and health of the society with the aim of substantiating hygienic standards, sanitary rules and measures which will provide the optimal conditions for vital functions, health consolidation and disease prevention.

ECOLOGY

Ecology (from Greek: οἶκος, "house"; -λογία, "study of”) is the scientific study of interactions among organisms and their environment, such as the interactions organisms have with each other and with their abiotic environment.

SHELLS OF THE EARTH

Atmosphere (New Latin atmosphaera, created in the 17th century from Greek ἀτμός [atmos] "vapor“ and σφαῖρα [sphaira] "sphere”) is a layer of gases surrounding a material body of sufficient mass of Earth that is held in place by the gravity of the Earth body.

Hydrosphere (from Greek ὕδωρ - hudōr, "water” and σφαῖρα - sphaira, "sphere”) is combined mass of water found on, under, and over the surface of planet Earth

Lithosphere (Greek: λίθος [lithos] for "rocky", and σφαῖρα [sphaira] for "sphere") is the rigid outermost shell of a rocky planet Earth.

Biosphere – this is total sum of ecosystems on the planet. Ecological relationships regulate the flux of energy, nutrients, and climate all the way up to the planetary scale. For example, the dynamic history of the planetary atmosphere's CO2 and O2 composition has been affected by the biogenic flux of gases coming from respiration and photosynthesis, with levels fluctuating over time in relation to the ecology and evolution of plants and animals.

MAIN OBJECTIVE OF HYGIENE

Preserving and strengthening of the human’s health

TASKS OF HYGIENE ① Studying the natural and anthropogenic environmental

factors and specific conditions affecting the health of a human being.

② Studying objective laws of the impact of environmental factors and conditions on the human body and population.

③ Scientific substantiation and development of hygienic standards, rules and measures for rational use of environmental factors beneficial for human body as well as removing the harmful factors or limiting them to safe levels.

④ Implementation of developed hygienic recommendations, rules and standards into practice in national economy, controlling and improving their effectiveness.

⑤ Predicting the sanitary situation for nearest and remote future, taking into account plans for their development of national economy, proper hygienic problems arising from the prognosed situation, scientific research of the problem.

SPECIFIC METHODS OF HYGIENE

Epidemiological (study of the human’s health).

Method of sanitary examination and description.

Method of hygienic experiment:a. Method of natural experiment;b. Method of laboratory

experiment.

Method of sanitary examination and /or expertise.

Method of hygienic teaching and study, sanitary education.

STAGES OF HYGIENIC DEVELOPMENT IN UKRAINE

STAGES OF HYGIENIC DEVELOPMENT IN UKRAINE

SANITARY LEGISLATION OF UKRAINE

1. State Constitution (1996).2. Health protection laws.3. The Law „On sanitary and epidemic welfare of the

population” (1995).4. Laws and Government resolutions on nature, air,

water and soil protection.5. State standards on industrial production,

foodstuffs, medicines quality (State Standards, certification of quality).

6. Building standards and rules (BSaR).7. Sanitary rules and standards (SanRaS).8. Hygienic standards: maximum allowable

concentration (MAC), maximum allowable level (MAL), maximum allowable dose (MAD), approximately safe influence level (ASIL), safe residual quality (SRQ), technical terms (TT).

WHAT REQUIRES THE KNOWLEDGE OF HYGIENE

State of population health analysis connected with living conditions. 

Diagnostics, defining etiology and pathogenesis of alimentary, professional and infectious diseases.

Administering treatment (in treatment-and-prophylactic institutions) and treatment-and-prophylactic (in dangerous enterprises) diet that assist in removing harmful substances from the body, rises the body resistance to their action.

Professional orientation (establishing correction of health level and chosen profession), medical expert examination.

Recommendations on daily regimen and personal hygiene.

Intrahospital infection prevention.

Conducting sanitary-educational work with people (in treatment-and-prophylactic establishments), in pediatric establishments (pediatric doctor), enterprises (medical dispensary doctor), in rural conditions (rural district doctor).
