【Weekly Medical Questions】is a new online column of "NEJM Medical Frontiers".
This column is based on NEJM Knowledge+, a sister product of the New England Journal of Medicine.
It pushes a question every Wednesday and announces the answers and detailed explanations on the next day.
The questions and content seem simple, but they are the core knowledge points and error-prone points of clinical practice; correct answers are not the goal, mastering the main points is the kingly way.
Ask the doctor every week to help you draw up the key points and save you time! Welcome everyone to leave a message in the comments section.
Your valuable comments and suggestions will be our best help! A 32-year-old previously healthy man complained of "diarrhea for 3 days"; the patient started to develop diarrhea one day after returning from a trip to Mexico.
He had watery stools 6 times a day, without blood, and denied fever, abdominal pain, or vomiting.
During the trip to Mexico, the patient ate a variety of meats, cheeses, and fresh fruits; the patient denied any contact with anyone suffering from gastrointestinal diseases.
Physical examination: normal body temperature, tachycardia, and heart rate of 110 beats per minute.
The mucous membrane is dry and the bowel sounds are hyperactive.
The abdomen is soft and no tenderness.
Which of the following bacterial pathogens is most likely to cause diarrhea in this patient? A Enterotoxigenic Escherichia coli B Staphylococcus aureus enterotoxin C Shigella toxin-producing Escherichia coli D Salmonella typhi E Shigella flexner The answer to the question is actually hidden in the question and abstract.
Do you have the answer? If you are not sure, you can share the content with your friends, and the discussion can make people think more clearly.
While answering the questions, please leave a message with your answers and diagnosis and treatment ideas to us.
The answer will be announced tomorrow, we will see or leave! Copyright information This article was translated, written or commissioned by the "NEJM Frontiers of Medicine" jointly created by the Jiahui Medical Research and Education Group (J-Med) and the "New England Journal of Medicine" (NEJM).
