Anti-tumor necrosis factor-alpha (anti-TNFα) medications are the most frequently used biologicals to treat inflammatory bowel disease (IBD). Little is known about the ocular side effects of this drug category. We present a case series of six young patients with Crohn disease (CD) and no previous ophthalmologic manifestations who developed blepharitis after commencing treatment with anti-TNFα therapy. Six otherwise healthy patients with CD, with no history of allergies or prior ocular complaints, developed blepharitis at a median of 7.5 months after the initiation of anti-TNFα therapy. All ophthalmic findings were treated topically. The ocular symptoms of two of the patients resolved shortly after discontinuation of the anti-TNFα treatment. The other four presented with relapsing-remitting symptoms. Blepharitis is a common ocular disease in the general population and an extra-intestinal manifestation in patients with IBD. It may be an adverse effect of anti-TNFα therapy in this patient population.

Background: Intra-articular corticosteroid injection (IACI), a common procedure in juvenile idiopathic arthritis, is usually associated with anxiety and pain. In a previous study, we concluded that nitrous oxide (NO₂) provides effective and safe sedation for such procedures. Following the introduction of medical clowns in our hospital, we added them as an integral part of the team performing IACI.

Objectives: To prospectively evaluate the effect of a medical clown on pain perception during intra-articular corticosteroid injection for juvenile idiopathic arthritis using NO₂ conscious sedation.

Methods: Patients scheduled for IACI first met and interacted with the medical clown. During the procedure, the rheumatologist and the medical clown worked in parallel to create distraction. NO₂ was administered. The patient, parent, physician, medical clown and nurse completed a visual analog scale (0–10) for pain. Change in heart rate ≥ 15% was recorded to evaluate physiologic response to pain and stress.

Results: A total of 46 procedures were performed in 32 children: 23 girls, 9 boys, with a mean age of 10.9 ± 3.6 years. The median visual analog scale pain score for the patients, parents, physicians, medical clown and nurses was 2, 2, 1, 1 and 1, respectively. Five patients had increased heart rate and experienced increased pain.

Conclusions: Active participation of a medical clown during IACI with nitrous oxide for juvenile idiopathic arthritis further decreases pain and stress and results in a positive patient experience.
