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. Besides, fluoride varnish is recommended for all children every 3-6 months from tooth emergence until they have a permanent dental home. This project aimed to increase oral fluoride varnish application for children starting at 6 months or the time of tooth eruption up to 3 years of age by at least 50% over 18 months. The stakeholders identified were physicians, nurses, medical assistants and the health information team. We obtained baseline data about oral health screening and fluoride varnish from both the clinic sites. The quality improvement (QI) project was based on Plan-Do-Study-Act (PDSA) cycles with a 6-month gap in-between the three cycles. For the first cycle, all medical staff members participated in 2-hour knowledge and skills training on dental caries and current recommendations on fluoride varnish. PDSA cycle 2 involved having automatic reminders for providers in electronic medical records. PDSA cycle 3 planned to have automatic fluoride orders for the recommended age groups. The QI team analysed the results after every 6 months, and improvements were made based on the input from data and medical staff. The number of patients who had fluoride varnish applied increased from 14% (n=50) to 55% at the end of PDSA cycle 3. Administration of the varnish did not affect the flow of the patients in busy primary care practice. The rate of improvement was across all the age groups, providers and in both clinical sites. It is possible to adhere to the oral fluoride varnish guidelines in a busy primary care practice, which may help benefit young children who are at risk for caries.

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.

Defining conditions that lead to the retention of water: the importance of the arterial sodium concentration.

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. METHODS: Volunteers collected urine q2h plus an overnight specimen; water loading was conducted after overnight food and water restriction; paired arterialized and venous blood samples were analyzed. RESULTS: When 20 mL water/kg was consumed in <15 minutes, the peak urine flow rate was 11 +/- 0.6 mL/min. The volume of water retained after water intake stopped, and when the urine was hyperosmolar, correlated directly with the daily excretion of sodium plus potassium (r(2)= 0.63). The plasma sodium concentration (P(Na)) was 4.0 +/- 0.5 mmol/L lower in arterialized than paired venous blood 30 to 40 minutes after water ingestion began (P < 0.01). In preliminary studies, the smallest water load consumed in 15 minutes that would reproducibly cause a water diuresis was defined in each subject. This same acute water load was retained, however, if it contained 150-mmol/L fructose, but not glucose, or if it was consumed slowly (sipping). The arterialized P(Na) was not significantly lower than in paired venous samples when water was sipped. CONCLUSION: A large fall in arterialized and not venous P(Na) best reflected the signal to induce a water diuresis. Although a very large water load can induce a water diuresis, smaller water loads can be retained for future heat dissipation.
