Nature includes the material world, especially that which surrounds humans but exist independently of human activities.
Such natural world includes the atmosphere (or the biosphere); physical things one can see such as the mountains, trees, animals or rivers;
man and the by-products of activities initiated by humans such as bush burning, mining, gas flaring, etc; wild land (forest, oceans, rivers) and micro-organisms.
All these constitute the ecosystem. Ideally, the ecosystem is in a stable state until man destabilizes this natural state.
These activities of man result in acid droplets from the atmosphere (pollution, global warming), release of radioactive substances, smoke,
dust which affect the ecosystem. Plants and plant-by products (such as grasses, trees, and flower pollen) and animal and animal by-products
(such as microbes and its activities) also destabilize the ecosystem by releasing toxicants which result to an unclean environment.
Medical science now realizes that the plethora of toxicants in the human environment (extrinsic and intrinsic) play major roles in disease and health,
through the air we breathe and susceptibility is dynamic. It is often stated that 60.0% of emerging infectious diseases that affect humans originate in animals
(zoonotic). The huge human population growth impact negatively on the environment through agriculture, deforestation, housing, acquisition of raw materials,
global warming, famine, water shortage, resource conflicts, domestication of animals, modern travel modalities, etc. These interruptive events further result
in environmental degradation.
These adverse events result in KNOTS most often in the respiratory tract since the toxicants are released into the air and man has to breathe in order to be alive.
The mechanisms for knotsformations are many and may include compression, inflammation restriction, muscle spasm, foreign body inhalation, etc.
The effects of knots are most pronounced in disadvantaged, weak malformed human species and contribution to these susceptibility include age, genetic,
and development aberrations, state of nutrition, inter-current morbidities and deficient immunity. These consequences are observable, preventable, predictable
and treatable. The ‘Watchman’ on applying appropriate untying means bring relief to the sick child, joy to the parents and potential healthy future leaders to a nation.
KNOTS, untied is unbearable and leads to marked discomfort, serious disease and ultimately death.
To succeed in untying nature’s knot on breath of life, ‘a watchman’ has to be empowered. Such empowerment include appropriate and relevant capacity building
for healthcare providers, available, accessible, and affordable health care facilities, availability of appropriate medical resources, and committed political leaders.
Then the pediatrician will watch with contentment the growth and development of a perfectly healthy community/nation.
The watchman’s activities therefore, include keeping watch over the environmentally unfriendly activities of man, the resultant toxicants of environmental degradation,
mechanism involved in formation and types of knots, identifying emerging diseases, and instituting preventive, curative and rehabilitative management options.
Some diseases of the Respiratory Tract are elaborated on in the lecture with the role of the watchman on Untying Knots emphasized. Such diseases include asthma,
Pneumonia, epiglottitis, obstructive sleep apnoea syndrome and the common cold. Other non respiratory tract conditions leading to ‘’knots’’ on community or national
health detected by the lecturer are illustrated such as, polypharmacy practiced by physicians and post partum sexual abstinence by a rural community.
Recommendations are made to untying various knots. These are aimed at making the air humans breath, clean and free from environmental toxicants.
These include restriction on human activities capable of destabilizing nature (Deforestation, flooding, military activities etc), combating microbes
(immunization, antimicrobials etc), mopping up of environmental toxicants,
minimizing consequences of environmental pollutants, provision of health education to communities, individuals, health care providers and empowerment of health care
facilities for acute case management and rehabilitation centers.
