161. 4-n-butylresorcinol, a highly effective tyrosinase inhibitor for the topical treatment of hyperpigmentation. (Full text)

4-n-butylresorcinol, a highly effective tyrosinase inhibitor for the topical treatment of hyperpigmentation. Hyperpigmentary disorders like melasma, actinic and senile lentigines are a major cosmetic concern. Therefore, many topical products are available, containing various active ingredients aiming to reduce melanin production and distribution. The most prominent target for inhibitors of hyperpigmentation is tyrosinase, the key regulator of melanin production. Many inhibitors of tyrosinase (...) , 4-n-butylresorcinol reduced visibly the appearance of age spots, while the control spots showed no improvement. A second study showed that 4-butylresorcinol was more effective than 4-hexylresorcinol and 4-phenylethylresorcinol.The present in vitro and in vivo data prove the high inhibitory capacity of 4-n-butylresorcinol on human tyrosinase activity, exceeding by far the potency of hydroquinone, arbutin and kojic acid. The resulting clinical improvement of skin hyperpigmentations reveals 4-n

173. Familial glucocorticoid deficiency presenting with generalized hyperpigmentation in adolescence. Report of three siblings (Full text)

Familial glucocorticoid deficiency presenting with generalized hyperpigmentation in adolescence. Report of three siblings Familial glucocorticoid deficiency (FGD) is a rare autosomal recessive disorder characterized by glucocorticoid deficiency, high ACTH levels and normal mineralocorticoid levels. FGD is caused due to defects in adrenocorticotropic hormone (ACTH) signaling. The defect can be caused by mutations in genes encoding the ACTH receptor (melanocortin 2 receptor) or its accessory (...) protein.Here we report three siblings with FGD. The second in order of siblings presented at an age of 15 years with history of diffuse hyperpigmentation since childhood. Their parents were non consanguineous. The patients were hyperpigmented and taller compared with their parents. None of the siblings had ambiguous genitalia or neurological abnormalities. There was no history of tuberculosis in the family. Biochemical investigations revealed low serum cortisol (<1 μg/dl) and elevated plasma ACTH (>1250 pg

Synergistic Combination of an In-office Procedure and Home Regimen for the Treatment of Facial Hyperpigmentation Hyperpigmentation disorders, such as melasma and solar lentigines, pose a significant treatment challenge for most patients. Combining a series of in-office procedures, such as chemical peels and light- and laser-based treatments, with maintenance therapies have been shown to provide greater efficacy than one treatment alone. However, receiving multiple in-office procedures may (...) . Physician-graded overall improvement in hyperpigmentation, standardized photography, and patient satisfaction were evaluated at Weeks 4, 8, and 12. At Week 12, all eight patients demonstrated improvements of at least 25 percent in overall facial hyperpigmentation, with six of the patients demonstrating a 50- or 75-percent overall improvement. One hundred percent of the patients rated their experience with the novel treatment regimen as "excellent" or "good" reflecting high patient satisfaction
