background: cutaneous leishmaniasis is an annoying and disfiguring disease affecting around 1,500,000 individuals globally. there are endemic pockets of this disease in taif region. in some patients, lesion often weeps and leads to scar formation. the study was conducted to see the efficacy of fluconazole and itraconazole in the patients of cutaneous leishmaniasis and the effect of these drugs ...

Antibodies against a conserved RNA-binding protein, the Ro 60-kDa autoantigen, occur in 24-60% of all patients with systemic lupus erythematosus. Anti-Ro antibodies are correlated with photosensitivity and cutaneous lesions in these patients and with neonatal lupus, a syndrome in which mothers with anti-Ro antibodies give birth to children with complete congenital heart block and photosensitive...

A series of non-photoautotrophic mutants of Chlamydomonas reinhardii was isolated by replica-plating mutagenized cells which had been grown in the dark. Many of these acetate-requiring mutants are photosensitive, showing poor growth on acetate medium in the light, but normal growth in the dark. Biochemical characterization showed that the photosensitive mutants all had specific lesions in photo...

Photocurrent therapy with participation of light and electrical stimulations could be an innovative and promising approach in regenerative medicine, especially for skin and nerve regeneration. Photocurrent is generated when light irradiates on a photosensitive device, and with more and more types of photosensitive materials being synthesized, photocurrent could be applied for enhanced regenerat...

A 63-year-old man was recently diagnosed with type 2 diabetes mellitus, for which he was taking metformin 1 g twice a day, and human immunodeficiency virus with a CD4 count of 5 cells/ μL, for which he was not yet started on antiretroviral therapy. The skin lesions started 6 days prior on the chest, but rapidly spread to include the entire trunk, neck, face, and all limbs. He also reported a 2-...

BACKGROUND GH treatment has become a frequently applied growth-promoting therapy in short children born small for gestational age (SGA). In some disorders GH treatment is contraindicated, eg, chromosomal breakage syndromes. Bloom syndrome is a rare chromosomal breakage syndrome characterized by severe pre- and postnatal growth deficiency, a photosensitive facial erythema, immunodeficiency, ment...

When taking different drugs, their possible side effects on the skin should be considered, including skin reactions connected to photosensitivity. This photosensitivity caused by drugs can appear as phototoxic reactions (which occur more often) or photoallergic reactions (which occur less often and include allergic mechanisms). The following drugs stand out as medications with a high photosensi...

Porphyria cutanea tarda is a metabolic disorder in the haem biosynthetic pathway. It includes a heterogeneous group of conditions, which may be inherited or, more commonly, acquired. Although porphyria cutanea tarda presents with cutaneous lesions only, it is often associated with systemic disease. A 64-year-old Chinese patient, who developed sporadic porphyria cutanea tarda 1 year after the di...

To understand the heterogeneity in genetic predisposition to skin cancer in different nucleotide excision repair-deficient human syndromes, we studied repair of cyclobutane pyrimidine dimers (CPDs) and of pyrimidine(6-4)pyrimidone (6-4PP) photoproducts in cells from trichothiodystrophy (TTD) patients. TTD is not associated with increased incidence of skin cancer, although 50% of the patients ar...

Background: Considering the prevalence of skin lesions and drug eruptions in intensive care units and the absence of research about it, we decided to study skin lesions of patients admitted in intensive care unit. Patients and Methods: In this descriptive study all patients admitted in intensive care units of Al-Zahra Hospital in Isfahan in 1376-78 were observed and examined by a resident in De...
