A previously healthy 11-year-old boy with multiple, unilateral lichen striatus (LS) on the left side of the body is described. The distribution of the lesions corresponded to the lines of Blaschko. Histology of the lesional skin was compatible with LS. Two years after the onset of the linear eruption, treatment with tacrolimus ointment resulted in significant improvement over a short period of ...

Lichen striatus is a self-limiting dermatosis presenting with sudden eruption of lichenoid papules along the lines of Blaschko. A 5-year-old girl presented with asymptomatic hypopigmented linear lesions over both upper limbs. The histopathological examination revealed spongiosis, vacuolar alteration of the basal layer and lymphocytic exocytosis with a mild-to-moderate perivascular mononuclear i...

Incontinentia pigmenti (IP) is a rare X-linked dominant neurocutaneous disorder affecting ectodermal tissue: skin, eyes, central nervous system, hair, nails, and teeth. It is usually lethal for males in utero. The involved gene is NEMO, an essential component of the nuclear factor-kappa B (NF-κB) signaling pathway. Skin lesions are highly diagnostic, occurring in neonates, with a particular dis...

Mammalian organs are known to decarboxylate a number of n-amino acids. Of the mammalian decarboxylases, 3,4-dihydroxyphenylalanine decarboxylase is probably the most studied. Blaschko (1) reported values for DOPAl decarboxylase in .liver and kidney of several animal species. The enzyme was shown to be deactivated by dialysis and its activity restored by the addition of pyridoxal phosphate (2, 3...

It now seems reasonable to postulate that in the hypothalamus there exists a mechanism that is peculiarly concerned with the release of ovulating hormone and through which changes in the external environment and in the ovarian hormones may influence pituitary function. Markee et al. (1948) produced ovulation by instilling epinephrine directly into the pars distalis or into the third ventricle. ...
