Improving oral health through dental fluoride varnish application in a primary care paediatric practice.

Dental caries affect 97% of people during their lifetime. A total of 59% of children aged 12-19 will have at least one documented cavity. The American Academy of Pediatrics recommends fluoridated toothpaste to all children starting at tooth eruption, regardless of caries risk.

Parapharyngeal abscess: A difficult diagnosis in younger children.

Parapharyngeal abscess is a difficult diagnosis to make in the pediatric population. Children <3 years of age present with fever, often the only sign at the initial presentation, thus causing a delay in diagnosis until the patient presents with more focal findings, such as a painful neck mass. Repeated follow-up visits with the patient until the diagnosis is confirmed are critically important to prevent complications.

Background: A water diuresis occurs when a large volume of water is ingested rapidly. Nevertheless, water conservation is required to provide a source of water for evaporative heat dissipation throughout the day. Therefore, the objective was to define conditions that permit the retention of ingested water.
