INDEX OF SUSPICION
This section of Pediatrics in Review reminds clinicians of those conditions that can present in a misleading fashion and require suspicion for early diagnosis. Emphasis has been placed on conditions in which early diagnosis is important and that the general pediatrician might be expected to encounter, at least once in a while. The reader is encouraged to write possible diagnoses for each case before turning to the discussion, which is on the following page. We invite readers to contribute case presentations and discussions. Case 1 Presentation A 13-year-old girl comes to you because it is so painful for her to urinate that she has developed acute urinary retention. Over the past 6 months she has had recurrent mild abdominal cramps; exactly 1 month ago she experienced a similar episode of dysuria. At that time she was able to urinate and was diagnosed by positive culture as having a urinary tract infection, for which she was treated. While preparing to catheterize her, you notice that this young woman is Tanner stage 5 in breast and pubic hair development, yet she states that she has never had a menstrual period. Her mother recalls her own menarche at age 11 years. Observations during the procedure allow you to determine the underlying cause of her problems.
