Microbiomes and wheat allergies: This week’s pediatrics briefing

I enjoy reading about the microbiome. Its biodiversity, dysfunction, and response to medical interventions are fascinating topics. This week, summary number 2 covers a pediatric part of this landscape: its relationship to later health.

Clinical Quiz

A 19-year-old female presents to her family physician with a six-month history of worsening acne, irregular menses, and difficulty sleeping. She mentions her last menstrual period was 45 days ago. On examination, she is overweight and excess hair is seen on her upper lip and chin. Laboratory tests reveal normal follicle-stimulating hormone (FSH) levels, elevated luteinizing hormone (LH) levels, and elevated testosterone levels. An ultrasound demonstrates the findings seen here. Based on this patient’s presentation, which of the following malignancies is she at greatest risk for as she ages?

A. Ovarian

B. Thyroid

C. Breast

D. Blepharitis

Editor’s Pearl

This week’s pearl comes from the radiology department of Cincinnati Children’s Hospital. They regularly share cases on Figure 1, and it was in the discussion of one of these cases that they shared the following:

We teach that small bubbly lucencies are not normal in babies because they do not have formed stool. Therefore, if you see them, think #Pneumatosis-intestinalis. The only caveat is in the setting of obstruction. Obstructed bowel can have more formed stool up stream.

Clinical Quiz Answer:

C. Endometrial.

This patient has polycystic ovarian syndrome (PCOS), a set of symptoms characterized by ovulatory dysfunction and excess androgen production. Patients with PCOS are at an increased risk of endometrial carcinoma and hyperplasia due to prolonged unopposed estrogen. Patients with PCOS are also at increased risk of type 2 diabetes, metabolic syndrome, and cardiovascular disease.
