However, after the 1966 International Covenant the global concern for the access to sufficient food only became more present, leading to the first ever World Food Conference that was held in 1974 in Rome, Italy. The Universal Declaration on the Eradication of Hunger and Malnutrition was a UN resolution adopted November 16, 1974 by all 135 countries that attended the 1974 World Food Conference. This non-legally binding document set forth certain aspirations for countries to follow to sufficiently take action on the global food problem. Ultimately this document outline and provided guidance as to how the international community as one could work towards fighting and solving the growing global issue of malnutrition and hunger. Adoption of the right to food was included in the Additional Protocol to the American Convention on Human Rights in the area of Economic, Social, and Cultural Rights, this 1978 document was adopted by many countries in the Americas, the purpose of the document is, "to consolidate in this hemisphere, within the framework of democratic institutions, a system of personal liberty and social justice based on respect for the essential rights of man. "A later document in the timeline of global inititaves for malnutrition was the 1996 Rome Declaration on World Food Security, organized by the Food and Agriculture Organization.
Inflammatory disease
Granulomatous disease, including sarcoidosis, granulomatosis with polyangiitis, and  midline granuloma, may also lead to nasolacrimal duct obstruction. Lacrimal plugs
As with similar cases of canalicular obstruction, dislodged punctual and canalicular plugs can migrate to and occlude the nasolacrimal duct. Neoplasm
Neoplasm should be considered in any patient presenting with nasolacrimal duct obstruction. In patients with atypical presentations, including younger age and male gender, further workup is appropriate. Bloody punctual discharge or lacrimal sac distension above the medial canthal tendon is also highly suggestive of neoplasm. Congenital
Congenital nasolacrimal duct obstruction, or dacryostenosis, occurs when the lacrimal duct has failed to open at the time of birth, most often due to an imperforate membrane at the valve of Hasner. Around 6% of infants have congenital nasolacrimal duct obstruction, or dacryostenosis, usually experiencing a persistent watery eye even when not crying. If a secondary infection occurs (Dacryocystitis), purulent (yellow / green) discharge may be present. Most cases resolve spontaneously, with antibiotics reserved only if conjunctivitis occurs. Lacrimal sac massage has been proposed as helping to open the duct, though this is not always successful. The aim of massage is to generate enough hydrostatic pressure (downward, toward the nose) to "pop" open any obstruction. Additional massage may then be performed up toward the lacrimal punctum, in order to express any infectious material out of the nasolacrimal sac. When discharge or crusting is present, the lids should be gently cleaned using cooled pre-boiled water or saline.
