Welcome to PICU Doc On Call, A Podcast Dedicated to Current and Aspiring Intensivists.

I'm Pradip Kamat and I'm Rahul Damania and we are coming to you from Children's Healthcare of Atlanta - Emory University School of Medicine.

Welcome to our PICU Doc On Call Mini-Case series. In this episode, we present a 15 year old girl who is admitted for shock after returning from her recent travel to NIgeria.

Here's the case:

13y F with no significant past medical history presents with 4 days of fever, headache, watery, non-bloody diarrhea, non-bloody, non-bilious emesis, decreased PO intake with worsening myalgias, fatigue, and weakness. She had traveled with her mother to Nigeria earlier this month and returned a week ago. Over the weekend mom consulted her pediatrician who prescribed an antiemetic without significant improvement of her symptoms. Once patient progressed to becoming light headed and weak, the mom decided to bring her to ED where she was found to be have tachycardia and hypotension. She required 3 L of crystalloid resuscitation was started an epinephrine continuous infusion and transferred to the PICU. Patient was found to have acute kidney injury with an elevated Cr, as well as a primarily direct hyperbilirubinemia and associated anemia and thrombocytopenia.

Her other history elements were notable for fever and difficulty breathing. Prior to traveling to Nigeria she did receive travel vaccinations and took mefloquine prophylaxis. She also had a negative COVID screen. While in Nigeria she denies exposure to animals, raw food intake, and only recalls that she may have had a few mosquito bites but this was well after returning from Nigeria until 7 days prior to presentation to the ED.

She presents to the PICU with hypotension, tachycardia at 160 bpm, tachypnea, and normal saturations. Her physical exam is notable for cool peripheral extremities, RUQ tenderness, and bilateral crackles.

She had no murmurs or gallops on her initial exam. Pertinently, she had no rash, lymphadenopathy or scleral icterus.

This is a teenage girl who has fever and constitutional symptoms after returning from travel abroad
She now presents with fluid refractory shock, tachycardia that is out of proportion to dehydration and signs of end-organ failure.
Notable negatives include: No LNadenopathy, hepatosplenomegaly, or a rash
Synthesizing these symptoms together → we are thinking that this picture may be related to a contracted infection or inflammatory condition related to her travel.
Let's transition into some history and physical exam components of this case.

What are key history features in this child who presents with fever and shock after a recent travel outside the US (Nigeria-West Africa)

Diarrhea and emesis days before presentation
High Fever with no rash
Mental status is maintained although she did have an headache
Light headed and weakness are symptoms suggestive of dehydration and even shock
Physical exam findings of importance here include- patient presenting with tachycardia, signs of poor perfusion such as delayed cap refill, cool extremities, hypotension. It is unique that even though she has RUQ pain there is no jaundice.

2. Are there some red-flag symptoms or physical exam components which you could highlight in a

patient with the above history and recent travel.

Weakness, light-headedness, shock, tachycardia, poor perfusion, fever and evidence of multi-organ dysfunction are suggestive of an acute and possibly life threatening infection acquired during travel. Given her travel to West Africa: I would be worried about falciparum malaria, dengue fever, typhoid fever, and cholera. Other diseases to be...
