Photodermatoses in skin of colour.

J Eur Acad Dermatol Venereol 2018 Nov 15;32(11):1879-1886. Epub 2018 Jul 15.

Department of Dermatology, Henry Ford Hospital, Detroit, MI, USA.

Photodermatoses represent a heterogeneous collection of disorders unified by the characteristic of being provoked through exposure to ultraviolet radiation. Generally, these conditions are classified into the following categories: immunologically mediated photodermatoses, chemical- and drug-induced photosensitivity, photoaggravated dermatoses and photosensitivity associated with defective DNA repair mechanisms or chromosomal instabilities. The list of photodermatoses is extensive, and each individual photodermatosis is understood to a different extent. Read More

Sparfloxacin-induced nail pigmentation: A case of fixed drug eruption?

Authors:
Husain Yahya

Ann Afr Med 2018 Jan-Mar;17(1):40-42

Dermatology Unit, Department of Medicine, Barau Dikko Teaching Hospital, Kaduna, Nigeria.

Sparfloxacin, a synthetic, second generation, broad spectrum aminodifluoroquinolone antibiotic, has excellent penetration into respiratory tissues and has good activity against Gram-positive, Gram-negative, and atypical bacteria. Although it is indicated for the treatment of adult community-acquired pneumonia and acute exacerbation of chronic bronchitis, its use has been limited by phototoxicity which is more common with it than with other quinolones. We report a case of a 20-year-old Nigerian woman who developed a diffuse blue-black nail pigmentation of thumb and big toe nails, 2 weeks after completing therapy with sparfloxacin, and a recurrence of the pigmentation in the same nails 1 year after taking the drug again.

Oral pigmentation in physiologic conditions, post-inflammatory affections and systemic diseases.

G Ital Dermatol Venereol 2018 Oct 19;153(5):666-671. Epub 2017 Apr 19.

Section of Dermatology, Department of Experimental, Diagnostic and Specialty Medicine, University of Bologna, Bologna, Italy -

Melanocytes are found throughout the oral mucosa but usually go unnoticed because of their relatively low level of pigment production. When focally or generally active in pigment production or proliferation they may be responsible for several affections in the oral mucosae ranging from physiologic pigmentation, systemic diseases to malignant neoplasms. The diagnosis of oral pigmentations (OP) is usually challenging for the physician, but a careful examination of the oral cavity may reveal the first manifestation of underlying systemic diseases.

Drug-induced photosensitivity: new insights into pathomechanisms and clinical variation through basic and applied science.

Br J Dermatol 2017 Apr 28;176(4):902-909. Epub 2017 Feb 28.

Betsi Cadwaladr University Health Board, Ysbyty Gwynedd, Penrhosgarnedd, Bangor, Gwynedd, LL57 2PY, U.K.

Drug-induced photosensitivity occurs when a drug is capable of absorbing radiation from the sun (usually ultraviolet A) leading to chemical reactions that cause cellular damage (phototoxicity) or, more rarely, form photoallergens (photoallergy). The manifestation varies considerably in presentation and severity from mild pain to severe blistering. Despite screening strategies and guidelines in place to predict photoreactive drugs during development there are still new drugs coming onto the market that cause photosensitivity. Read More

Pier Luigi Dodi

Vet Med (Auckl) 2015 30;6:341-347. Epub 2015 Oct 30.

Department of Veterinary Medicine Sciences, University of Parma, Parma, Italy,

Keratoconjunctivitis sicca (KCS) is a frequent canine ophthalmic disease, resulting from the deficiency of one or more elements in the precorneal tear film. There are different known causes of KCS in dogs, including congenital, metabolic, infectious, drug induced, neurogenic, radiation, iatrogenic, idiopathic, and immune mediated, though the last one is the most prevalent form in dogs. Initially, clinical signs of KCS include blepharospasm caused by ocular pain, mucoid to mucopurulent ocular discharge, and conjunctival hyperemia; secondary bacterial infection may also occur, with chronicity, corneal epithelial hyperplasia, pigmentation, neovascularization, and corneal ulceration.

[Pigmentary disorders induced by anticancer agents. part I: chemotherapy].

Ann Dermatol Venereol 2013 Mar 11;140(3):183-96. Epub 2013 Jan 11.

Dermatologie, centre de lutte contre le cancer, institut Claudius-Regaud, 20-24, rue du Pont-Saint-Pierre, 31052 Toulouse, France.

The occurrence of hyperpigmentation during chemotherapy is one of the most frequent dermatological adverse events observed with these drugs. It may arise with numerous anticancer agents, and can be either localized or diffuse, occurring either immediately or after inflammatory dermatological lesions. Nails, mucosa and skin may all be affected. Read More

Drug-induced generalized skin eruption in a diabetes mellitus patient receiving a dipeptidyl peptidase-4 inhibitor plus metformin.

Diabetes Ther 2012 Dec 6;3(1):14. Epub 2012 Nov 6.

Division of Diabetes, Clinical Nutrition and Endocrinology, Department of Internal Medicine, Kasai Electric Power Hospital, 2-1-7 Fukushima, Fukushima Ward, Osaka City, 553-0003, Japan.

A generalized skin eruption with strong itching was induced by sitagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor, in a patient almost 6 months after initiation of the drug. Physical examination revealed a spread of skin rash from chest to back, and abdomen and thigh. Discontinuation of the drug eliminated the skin rash immediately. Read More

[Pigmented lesions of the oral mucosa].

Hautarzt 2012 Sep;63(9):704-9

Univ. Klinik für Mund-, Kiefer- und Gesichtschirurgie, Paracelsus Medizinische Privatuniversität Salzburg, Müllner Hauptstr. 48, 5020, Salzburg, Österreich.

The oral mucosa contains melanocytes, even though one might not suspect this when examining white subjects. Drug-induced pigmentation is usually irregularly distributed over the oral mucosa; typical causes are contraceptives and tetracyclines. Localized traumatic pigmentation can be due to injuries contaminated by foreign material (dust). Read More

Sensitivity to dioxin decreases as zebrafish mature.

Toxicol Sci 2012 Jun 8;127(2):360-70. Epub 2012 Mar 8.

Department of Biomolecular Chemistry, University of Wisconsin, Madison,Wisconsin 53705, USA.

The embryos of teleost fish are exquisitely sensitive to the toxic effects of exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). However, several lines of evidence suggest that adults are less sensitive to TCDD. To better understand and characterize this difference between early life stage and adults, we exposed zebrafish (Danio rerio) to graded TCDD concentrations at different ages. Read More

Photoinduced dermatitis and oral lichenoid reaction in a chronic myeloid leukemia patient treated with imatinib mesylate.

Photodermatol Photoimmunol Photomed 2012 Feb;28(1):2-5

Institute of Dermatology, University of Pavia and Foundation IRCCS Policlinico S. Matteo, Pavia, Italy.

Background: Imatinib mesylate (IM) is a phenylaminopyrimidine that represents the first-line treatment for chronic myeloid leukemia (CML), Philadelphia chromosome-positive. It acts as a potent and selective inhibitor of the bcr-abl fusion protein by a competitive inhibition at the adenosine triphosphate-binding site of the enzyme, which leads to the inhibition of tyrosine phosphorylation of the proteins involved in bcr-abl signal transduction. IM is generally well tolerated and usually provokes only mild side effects consisting of nausea, myalgia, edema and muscle cramps. Read More

Dysfunction of melanocytes in photoleukomelanoderma following photosensitivity caused by hydrochlorothiazide.

Photodermatol Photoimmunol Photomed 2011 Dec;27(6):328-30

Division of Dermatology, Department of Internal Related, Kobe University Graduate School of Medicine, Kobe, Japan.

We report a 68-year-old Japanese man who developed photoleukomelanoderma following prolonged photosensitivity caused by hydrochlorothiazide. He showed complete recovery from the leukomelanoderma with the discontinuation of the responsive drug and with topical application of tacrolimus hydrate and corticosteroid. Histological and immunohistochemical examination revealed that there were no melanin-positive cells in the hypopigmented area, despite the presence of melanocytes. Read More

Q-switched laser treatment of amiodarone pigmentation.

Authors:
Eric F Bernstein

J Drugs Dermatol 2011 Nov;10(11):1316-9

Main Line Center for Laser Surgery, 32 Parking Plaza, Ardmore, PA 19003, USA.

A number of drugs can cause cutaneous hyperpigmentation through a variety of mechanisms. The pigment is comprised of dermal deposits of the drug and its metabolites, often combined with melanin and hemosiderin. Minocycline and amiodarone are among the most common medications to cause skin-induced pigmentation. Read More

Pigmented lichenoid drug eruption secondary to chloroquine therapy: an unusual presentation in lower lip.

Minerva Stomatol 2011 Jun;60(6):327-32

Department of Stomatology and Oral and Maxillofacial Surgery, São Leopoldo Mandic Dental School Campinas, Brazil.

Antimalarial drugs, like chloroquine, may produce hyperpigmentation of the oral mucosa, affecting most commonly the palate. Its pathogenesis is not clear; an increased production of melanin is currently believed to be the cause of this oral manifestation. The purpose of this study was to report a case of atypical oral mucosal hyperpigmentation secondary to antimalarial therapy. Read More

Embryotoxicity and biotransformation responses in zebrafish exposed to water-soluble fraction of crude oil.

Bull Environ Contam Toxicol 2011 Apr 15;86(4):389-93. Epub 2011 Mar 15.

Department of Pharmacology, Federal University of Paraná, Curitiba, PR, Brazil.

The toxic effects of water-soluble fraction (WSF) of crude oil (API27, Petrobras Campos Basin, Brazil) were evaluated during the early life stages of zebrafish, as well as its biotransformation in juvenile fish. Embryonic development was studied during 96 h. Reduced heartbeat rate, weak pigmentation, tail defects, and embryo mortality were observed for all of the tested concentrations of the WSF. Read More

Miki Tanioka

J Dermatol 2011 Jan;38(1):41-4

Department of Dermatology, Graduate School of Medicine, Kyoto University, Kyoto, Japan.

One of the recent advances in dermoscopy is the significance of parallel ridge pattern (PRP), which has 99% specificity in detecting both melanoma in situ and advanced melanoma on the acral volar skin. This review features exceptionally benign acral lesions showing PRP on dermoscopy. These benign lesions can be distinguished from malignant melanoma, because of the typical clinical history and associated symptoms. Read More
