When I saw Mrs. XYZ elderly female patient was brought to my OPD for my consultation by her family member. The patient was blissfully unaware of the fact that her foot wound had crawling maggots! Knowing that she was a diabetic for the last 15 years I decided to do a complete foot and limb evaluation as well a complete examination of the patient. I learnt that she was psychologically depressed.
Kalabhairav et al. (Sat,) studied this question.
