A 3 month old male born full term with no complications presents for a right groin mass. His mother first noticed it two days ago when he cried. Otherwise, he has been acting normally, drinking formula regularly, and having several bowel movements daily. Vital signs and weight are within normal limits for age. Exam shows a happy appearing infant that cries when taken away from his mother. When he cries, a 3 cm soft, non-tender mass is appreciated in the right inguinal region that is easily reducible. There is no overlying erythema or skin changes. Genital exam reveals palpable bilateral testes with no additional masses in the scrotum. Which of the following is the most appropriate management of this condition?

A: admit for observation

B: discharge with expedited surgical follow up

C: discharge with reassurance that it will likely spontaneously resolve

D: emergent surgical consultation

Answer: discharge with expedited surgical follow up

This infant is presenting with a reducible inguinal hernia that increases in size with increased intra-abdominal pressure such as with crying or straining. It is most common in premature males in the first year of life. Unlike in adults, children require surgical referral for interval repair of simple reducible inguinal hernias due to the higher risk of incarceration. Thus, reassurance that it will likely spontaneously resolve without surgical follow up is incorrect. If the hernia was incarcerated, emergent surgical consultation with admission for prompt surgical repair would be appropriate management.

A 62-year old male with a past medical history of hypertension, hyperlipidemia, and coronary artery disease presents with chest pain. He was discharged from the hospital 2 days ago after being treated for a STEMI which occurred 5 days ago. The pain is mid-sternal, worse with deep inspiration and lying flat. He has been taking all of his medications including aspirin and clopidogrel as instructed. Vital signs are: BP 142/76, HR 102, T 37.2 C, RR 18, SpO2 96%. On exam, he is sitting upright and appears in mild discomfort but otherwise has no focal findings. EKG shows Q waves in II, III, and aVF without significant other changes. POCUS reveals a small circumferential pericardial effusion with a normal ejection fraction. Which of the following is the first line treatment of this patient’s suspected condition?

A: colchicine

B: heparin

C: high dose aspirin

D: naproxen

E: prednisone

Answer: high dose aspirin

This patient is presenting with peri-infarction pericarditis which is an uncommon complication of STEMIs due to the increasing use of reperfusion therapy. Despite not having classic EKG changes suggestive of pericarditis, he meets diagnostic criteria for acute pericarditis. According to the American College of Cardiology and American Heart Association, high dose aspirin (650 mg every 6 hours) is the first line treatment of acute pericarditis after STEMI (Class I recommendation). In contrast to viral, idiopathic, or autoimmune causes of pericarditis, NSAIDs such as naproxen or glucocorticoids are not recommended due to potential for myocardial scar thinning and infarct expansion. Colchicine may be used as an adjunctive medication if high dose aspirin is not effective. Heparin is not recommended for the treatment of acute pericarditis. 

Diagnostic Criteria for Acute Pericarditis (requires 2 of the following)

Characteristic chest pain (sharp or pleuritic, improved sitting up and leaning forward, worse lying down)

Pericardial friction rub

New or worsening pericardial effusion

Suggestive EKG changes (diffuse ST segment elevations)
