Prevalence of a delayed diagnosis of caffeine poisoning in the emergency department of a Japanese hospital.

Background: Most cases of acute caffeine poisoning are easily diagnosed at initial hospital visits. Nonetheless, accurate diagnosis is sometimes delayed in some patients with this condition. Therefore, our aim was to determine the prevalence of delayed diagnosis of acute caffeine poisoning in the emergency department (ED).

A cross-sectional study of anterior cutaneous nerve entrapment syndrome at a Japanese emergency department.

This study aimed to clarify the proportion of ACNES cases among those of abdominal pain and the clinical characteristics and prognosis of the disease in an emergency department (ED) of a Japanese general hospital.

Methods: The medical records of patients from January 2014 to December 2023 were reviewed, and patients aged 15 years or older with abdominal pain with positivity for Carnett's sign, a good response to trigger point injection (TPI), and an ACNES diagnosis were included.
