Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants.

Drug Dosing: Obese Patients

350
In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Summary
This summary is machine-generated.

Adenotonsillectomy (T&A) is associated with significant weight gain in obese children, but not in normal-weight or overweight children. Pre-T&A weight reduction counseling is recommended for obese children.

Area of Science:

  • Pediatric Endocrinology
  • Otolaryngology
  • Obesity Medicine

Background:

  • Adenotonsillectomy (T&A) is a common surgical procedure in children.
  • The association between T&A and subsequent weight changes requires further investigation.

Purpose of the Study:

  • To investigate the relationship between adenotonsillectomy and weight gain in pediatric patients.
  • To determine if T&A influences weight trajectory across different BMI categories.

Main Methods:

  • Retrospective case-control study involving 154 children who underwent T&A and 182 controls.
  • Weight and height were tracked at 6-month intervals for 24 months post-procedure.
  • Analysis utilized multilevel mixed-effects regression, stratifying by normal weight, overweight, and obese categories.

Main Results:

  • Children undergoing T&A showed increased weight gain compared to controls at all intervals.
  • Obese children who had T&A gained significantly more weight (4.2 kg difference at 24 months) than obese controls.
  • No significant weight or height differences were observed in normal-weight or overweight groups post-T&A.

Conclusions:

  • Adenotonsillectomy is linked to substantial weight gain specifically in obese children.
  • Weight reduction counseling should be considered for obese children prior to undergoing T&A.
