Assessing the potentials of two local topical ointments as affordable treatment against tungiasis infestation: A self-experimentation in Igbokoda, Nigeria

Infestations caused by penetration of Tunga penetrans (Siphonaptera: Hectopsyllidae) in cutaneous sub-layers present morbidities and resulting mortalities if surgical treatment remains the obtainable. Considering the neglected nature of this infestation and the absence of marketable product, we report an observation on the use of grounded naphthalene in kerosene ointment, and powder of Piper guineense in coconut oil ointment as affordable treatment of embedded tungiasis flea in Igbokoda. A total of 80 individuals partitioned into two groups of 40 individuals each were assigned the locally made topical ointment irrespective of stages of tungiasis lesions. The mean of stage I, II and III tungiasis lesions treated with grounded naphthalene in kerosene ointment respectively decreased from 1.83, 3.42 and 3.89 to 0 after 5–6 days (p < .05). Also, the mean of stage I, II and III tungiasis lesions treated with grounded P. guineense ointment respectively decreased from 1.52, 3.10 and 5.00 to 0 after 6 to 7 days of treatment exposure (p < .05). Very high significant difference between stages and exposure days of participants assigned the two topical ointment was recorded p < .0001 and p = .0005 respectively. Naphthalene ointment and to a lesser extent P. guineense ointment is best to control and hinder development cycle of embedded fleas irrespective of infested part and stage of infection.
