This research refers to the case study of a patient, a male college student, who was given psychotherapeutic care. Initially, the patient self-referral to the Mental Health area, which is a service permanently offered by the Autonomous University of the State of Mexico, through the Research Center in Medical Sciences (CICMED). The process of the case allowed analyzing the administrative procedure that operates in the CICMED and the process between this and the educational establishment in which the patient studied.

In three provinces of the Philippines (Quezon, Northern Samar and Zamboanga del Sur), 11,378 children between 6 and 83 months of age were examined for signs of xerophthalmia and weighed to determine weight-for-age status. Xerophthalmia prevalence ranged from 1.6% to 4.4% for nightblindness and 0.6% to 2.7% for Bilot's spots in the three provinces indicating a serious vitamin A deficiency problem. These levels contrast sharply with the recent national xerophthalmia prevalence (0.7% for night blindness and 0.2% for Bitot's spots). There was a preponderance of mild xerophthalmia among males, and among children 4-6 years of age. No consistent association between weight-for-age status and xerophthalmia was found. The study recommends the universal distribution of vitamin A to children in high-prevalence regions, rather than the current practice of providing vitamin A supplements to moderately and severely underweight children identified through the annual village-based child weighing sessions, to ensure reaching children most at risk for xerophthalmia. The study also suggests the need for regional vitamin A assessments to identify areas endemic for vitamin A deficiency because the aggregate national prevalence may mask a more serious localized problem.
