Human immunodeficiency virus infection and pregnancy.

Human immunodeficiency virus infection profoundly affects the medical community and is spreading rapidly in women of childbearing age worldwide. Transmission of HIV from mother to child can occur in utero, during labor, or after delivery through breast-feeding. Most of the infants are infected during delivery.

Polymorphic eruption of pregnancy.

Polymorphic eruption of pregnancy (PEP) is a benign, self-limiting, pruritic disorder of pregnancy, which usually affects the primigravida during the last trimester or immediately postpartum. Its pathogenesis is unclear and its clinical manifestations are variable, leading frequently to an incorrect diagnosis. In cases of PEP the histological findings are nonspecific and the laboratory results, including direct immunofluorescence (DIF) and indirect immunofluorescence (IIF), are negative.

Optimal management of recalcitrant disorders of hyperpigmentation in dark-skinned patients.

Alterations in skin pigmentation may often have a dramatic expression in individuals with a dark skin complexion and can be a source of significant emotional distress in these individuals. Hyperpigmented disorders such as melanosis (melasma), post-inflammatory hyperpigmentation, drug-induced hyperpigmentation, and erythema dyschromicum perstans tend to have a prolonged course and, in many cases, are refractory to treatment, further contributing to the psychological impairment of the affected patients. Melanosis, is a common form of facial pigmentation attributable to sunlight and hormonal factors.

Spectrum of idiopathic photodermatoses in a Mediterranean country.

Background: Idiopathic photodermatoses are considered to be common disorders in the population of northern latitude countries, presumably because of the dominance of more "sun-sensitive" individuals with a light-skinned complexion. The incidence of these disorders in the Mediterranean or tropical countries is often under-appreciated because of the higher degree of perennial presence of sunlight and the prevalence of darker skin-type individuals who are seemingly more resistant to the development of sun sensitivity.

Methods: We performed a retrospective, chart-based review of all patients who were diagnosed with idiopathic photodermatoses at a photodermatology referral center in Athens, Greece, during a period of 10 years.

Polymorphous light eruption.

Polymorphous light eruption (PLE) is a common idiopathic photosensitivity disorder with an estimated prevalence of 10-20%. It is characterized by an intermittent skin reaction to ultraviolet (UV) radiation exposure, consisting of non-scarring pruritic erythematous papules, vesicles or plaques that develop on light-exposed skin. Despite the different morphology in different individuals, the eruption tends to have a monomorphous presentation in any single subject.

An epidemiological study of syphilis incognito, an emerging public health problem in Greece.

Background: Syphilis incognito is a subtype of latent syphilis (early or late) characterized by no signs or symptoms of primary or secondary syphilis and diagnosed by positive serologic results for syphilis during routine screening.

Objective: To study the epidemiological characteristics, causes, and implications of syphilis incognito in Greece.

Patients And Methods: All new adult patients diagnosed as having syphilis in Andreas Sygros Hospital for Skin and Venereal Diseases, Athens, Greece, from 1989 through 1996 were studied prospectively and retrospectively (history, physical examination, serologic tests, cerebrospinal fluid examination, and imaging) to determine the stage of their disease.
