Suicide by self-poisoning is a common cause of death, especially in the younger population. More specifically, hair-dye poisoning is being increasingly used for suicide. Paraphenylenediamine (PPD), also known as "Kala pathar", is a highly toxic ingredient present in hair-dye that can cause death. Therefore, this study is designed to assess the demographics, clinical features, laboratory findings, and outcomes of PPD poisoning in patients admitted to the National Poison Control Center in Karachi, Pakistan.
Materials and methodsWe conducted a prospective study for a period of six months at the National Poison Control Center, Karachi, Pakistan. A total of eight patients with PPD poisoning with no cardiac, liver, or renal co-morbidities were included in this study. The demographic characteristics, clinical features, laboratory findings, mode of intoxication, and route of intoxication were noted in a proforma. Furthermore, hospitalization time, tracheostomy status, mechanical ventilation status, and mortality rates were also recorded. For continuous variables, the means and SDs were calculated. Whereas for categorical data, percentages were calculated.
