can a diagnosis of tenia versicilor be made in infants. if so what could be the mode of transmission and immunology?
Do you mean pityriasis versicolor which is a fungal infection. Tenia is wrong. Tinea versicolor is a synonym of pityriasis versicolor. It is easy to diagnose
- The disquamative lamina are very characteristic of pityriasis versicolor. The sqames can be loosned as a single unit encompassing single unit of the area, if small. This can be done with stripping tape and the squames subsequently stained by methylene blue or any other.
- Wood's lamp examination will show a golden yellow florescence
- KOH examination of the scrapings for fungus
The causative agent is Malassezia furfur which is present in normal skin flora. In some persons it causes the disease.
Dear Venkata, clinically it is not known that cases of ptyrisis Versicolor detected in neonates but colonization of the skin by M. furfur starts soon after birth and progresses until the age of about 3 months, probably reflecting the activity of the sebaceous glands during this period. This yeast has been a cause of systemic infections in infants receiving intravenous lipids, and it is presumed that the source of organisms in such cases was the skin. It is now believed that M. furfur and M. sympodialis may be a frequent cause of erythematous papulopustular eruptions occurring on the face and scalp in neonates, a condition now widely termed neonatal cephalic pustulosis, though not all neonates with this clinical presentation had detectable Malassezia in the lesions. This type of rash was reported to have a frequency of 10% in neonates seen as outpatients in a paediatric dermatology
department with pustule contents showing M. furfur yeasts in over half of these, associated with a good therapeutic response to topical application of 2% ketoconazole cream for 15 days in almost every case. A frequency of 66% was reported in a recent study, with 62% being culture-positive for Malassezia .
