ABSTRACT
Hair dye ingestion is an uncommon form of poisoning in the west, however, in some parts of the world such as East Africa and Indian Sub-continent it is not uncommon. The main component of hair dye causing toxicity is Paraphenylenediamine (PPD). This compound has been found to cause angioneurotic edema, rhabdomyolysis and renal failure. We present a case of hair dye poisoning who presented with respiratory distress due to laryngeal edema and later developed trismus and carpopedal spasm. This case report highlights the combined toxicities of sodium EDTA and PPD.

Paraphenylene diamine (PPD) is a major component of hair dyes. The aim is to study the renal manifestations and outcome of PPD consumption. During a four-year period from 2002 to February 2006, 10 persons were admitted to our Institute after consuming a hair dye in a suicidal bid. The percentage of ARF due to PPD at our Institute was 0.95%. Seven patients out of 10 (70%) who consumed PPD developed ARF. All 10 patients, including the patients who had normal renal function had features of rhabdomyolysis. Two patients required ventilator support for respiratory distress and two more required tracheostomy due to upper airway tract edema. One patient has expired after two sessions of dialysis. Renal biopsy in two patients (one, postmortem) showed acute tubular necrosis along with presence of casts in tubules due to myoglobin.
