Both the pattern and absence of sweating was documented by using the starch-iodine test which followed the similar glove and stocking distribution (Figures 1 and 2).
Our case here shows a similar pattern of loss of sensation and sweating in the lepromatous pole which has been pictographically documented by the use of a starch-iodine test. The patient had heat intolerance due to the loss of his ability to sweat which impaired his quality of life.
The results were assessed by the hyperhidrosis disease severity index, improvement of sweating on a scale of I to IV and the starch-iodine test. Any adverse events were noted.
No patient underwent a Minor's starch-iodine test. (During this test, a solution of iodine, castor oil, and absolute alcohol is applied to the patient's cheek and then dusted with powder.) Almost all patients who undergo Minor's test will exhibit objective Frey's syndrome.
All 24 patients were evaluated via a short questionnaire, the starch-iodine test, and a visual examination.
At follow-up, all patients completed a short questionnaire survey and underwent a starch-iodine test.
In addition, all patients were evaluated for Frey's syndrome via the starch-iodine test. This test was performed on both sides of the face, the nonoperated side serving as a control.
However, the starch-iodine test on the operated side was mildly positive in 6 of the 12 patients (50%) in the nonflap group, whereas none of the patients in the flap group had a positive result.
