Introduction: Hypercalcemia secondary to vitamin D intoxication is a rare condition resulting from inadequate prescription. It is characterized by nonspecific symptomatology and can produce severe neurological, muscular, gastrointestinal, renal, and cardiovascular manifestations. Clinical case: We describe the case of an 86-year-old woman with a history of vitamin D supplementation for three months after hip arthroplasty. The initial presentation was gastrointestinal symptoms and sensorimotor disturbance. Hypercalcemia was found upon evaluation. After ruling out the main organic causes, vitamin D intoxication was suspected, which was confirmed after testing for 25-hydroxyvitamin D levels. Correction of hypercalcemia was performed, and the patient had a favorable clinical evolution.  Conclusion: It is important to consider vitamin D intoxication as a differential diagnosis of hyperca...

Objective: To determine the factors associated with COVID-19 vaccination in medical students from Universidad Peruana Los Andes. Materials and methods: An observational, analytical and cross-sectional study. A total of 243 second- to tenth-academic term students completed a questionnaire about sociodemographic and academic characteristics, family and personal medical history, and the number of COVID-19 vaccine doses received. To determine the association, chi-square test and Student’s t-test were used. Results: Vaccination coverage was 98.77 %, out of which 61.73 % had three doses. In addition, 46.50 % of the students reported having been infected with COVID-19 at least once. The bivariate analysis showed that age (p = 0.047) and place of residence (p = 0.042) were significantly associated with the vaccination status. Conclusions: Although vaccination coverage was very high, it should ...
