We're back with journal club to review a study evaluating the PECARN guidelines on febrile infants under 28 days of age and serious bacterial infections like meningitis.

Key Points:

• Urinalysis, absolute neutrophil count, and procalcitonin are useful predictors of serious bacterial infection
• In this study, using urine studies, absolute neutrophil count, and procalcitonin were able to risk stratify patients into risk for meningitis and no cases of meningitis were missed

Dealing with a crying and moving child who needs sedation for a laceration repair? Intranasal midazolam is a good sedative option but what dose do you choose? Learn more in this journal club episode where we talk about a recent study that evaluated the most effective dosing of intranasal midazolam.

• Intranasal midazolam is a good non-invasive sedative option. It has similar plasma concentrations as intravenous administration because it bypasses first pass metabolism unlike oral administration. Onset of action is 20-30 minutes and can last 30-60 minutes.
• Dosing of intranasal midazalam for children is 0.2 - 0.5 mg/kg
• Based on the results of this study, 0.4 - 0.5 mg/kg of midazolam was found to provide more effective sedation without increased adverse events for the studied patient population (6 months - 7 years old with simple laceration)
• Always critically think through studies! This study had limitations including the narrow patient population (did not include children with autism or developmental delay, did not include children less than 6 months old, and had a small study sample size with n = 101)

Sometimes kids are FOS - full of stool! In today's episode, we talk about how to diagnose and treat functional constipation which is a common cause of abdominal pain in pediatrics and can be a pain in the butt, literally!

Key Points:

• Functional constipation is constipation not due to any other underlying conditions such as Hirschsprungs, spinal cord dysphraphism, or other disease.
• Functional constipation is defined as having at least 1 month of symptoms in kids younger than 4 years old (or) symptoms at least once per week for at least 2 months in kids older than 4 years old who do not meet IBS criteria. Symptoms include 2 or fewer stools per week, at least 1 episode of incontinence per week after toilet training is established, a history of excessive stool retention/retentive posturing/excessive volitional stool retention, a history of hard or painful bowel movements, the presence of large fecal mass in rectum, or a history of large diameter stools that may obstruct the toilet
• Encopresis is liquid stool that goes around large stool balls and is indicative of constipation rather than diarrhea
• Polyethylene glycol (PEG, miralax), lactulose, and enemas are all good treatment options for constipation
