Long-term remission of recurrent herpes labialis following topical imiquimod application on distant healthy skin: a clinical and immunological study.

Background: Given the limitations of current antiviral therapies, safer and more effective approaches to the management of recurrent herpes labialis (RHL) are needed.

Methods: A patient with a 23-year history of RHL and 14 healthy individuals were studied. The patient applied imiquimod to distant healthy skin for 3 weeks.

Topical application of imiquimod induces alterations in peripheral blood lymphocytes in healthy individuals.

The aim of this study was to determine whether imiquimod, a Toll-like receptor-7/8 agonist, in addition to its well-known topical action on the cutaneous immune response, might also induce alterations in the peripheral blood lymphocytes. A 62.5 mg quantity of imiquimod (5% cream) was applied topically under occlusion once daily every second day for 3 weeks to the skin of 10 healthy volunteers, age range 30-57 years.

Epileptic seizures as the sole manifestation of neuro-Behçet's disease: complete control under interferon-alpha treatment.

Behçet's disease (BD) is a multisystemic disease of unknown etiopathogenesis with various clinical features including manifestations from central nervous system involvement. We report the case of a patient presented with a 20-year history of BD and a 10-year history of epileptic seizures refractory to various antiepileptic drugs. Under systemic treatment with interferon-alpha 2a (IFN-alpha) a complete remission of the cutaneous manifestations and a seizure-free state were achieved.

Reduced expression of the antiapoptotic proteins of Bcl-2 gene family in the lesional epidermis of patients with Darier's disease.

Background: Dyskeratotic cells in Darier's disease (DD) are thought to represent apoptotic keratinocytes. Bcl-2 gene family proteins play a major role in the regulation of apoptosis of epidermal keratinocytes and reveal pleiotropic interactions with intracellular Ca2+ homeostasis. The latter is impaired in DD because of mutations of ATP2A2 gene that encodes the type 2 isoforms of the sarcoplasmic/endoplasmic reticulum (ER) Ca++ ATPase 2 (SERCA2) pump.

Short-term oral isotretinoin therapy does not cause clinical or subclinical peripheral neuropathy.

Background: Subclinical neurophysiologic abnormalities mainly suggestive of sensory fibers dysfunction were observed in some patients after 1 and 3 months of treatment with oral acitretin. Moreover, two cases of peripheral sensory neuropathy and one of sensorimotor polyneuropathy were observed after short-term oral administration of this compound.

Objective: The objective of this prospective study was to investigate whether short-term treatment with oral isotretinoin can also affect peripheral nerve function.

Ehlers-Danlos type IV syndrome in a patient with Down syndrome: simple co-occurrence or true association?

Down syndrome, a common chromosome aneuploidy, has been associated with an increased incidence of cutaneous disorders. The simultaneous occurrence with Ehlers-Danlos syndrome (EDS) is rare. We report here the clinical case of a 19-year-old female patient with Down syndrome (trisomy 21) who was also affected by EDS type IV.

Hsp27 expression coincides with epidermal stratification during human epidermal morphogenesis.

Heat shock protein 27 (Hsp27), apart from its protective function in response to stress, is implicated in the regulation of cell growth, differentiation and apoptosis. Data on the expression of Hsp27 in the developing human epidermis are sparse and partially conflicting. Thus, the purpose of the present study was to investigate Hsp27 expression during the morphogenesis of human epidermis.

Short stature, type E brachydactyly, exostoses, gynecomastia, and cryptorchidism in a patient with 47,XYY/45,X/46,XY mosaicism.

We report a 72-year-old male patient with a 47,XYY/45,X/46,XY mosaicism associated with short stature, exostoses, type E brachydactyly, gynecomastia, cryptorchidism, mild mental retardation, and a paranoid personality and conversion disorder. Since his prevalent cell line was 47,XYY (about 75%), our patient could be karyotypically classified as a case of 47,XYY syndrome. In view of the striking similarity of the clinical features of this case and those of a XYY case previously reported by Ikegawa et al (1992), it seems reasonable to suggest that these patients are representatives of a novel syndrome with a XYY karyotype.

Anaphylactic shock as the only clinical manifestation of hepatic hydatid disease.

The case of a 35-year-old man is reported who developed a spontaneous anaphylactic shock as the only clinical manifestation of hepatic hydatidosis. Dermatologists should consider asymptomatic hydatid disease in the differential diagnosis of anaphylactic reactions, particularly in patients from regions in which echinococcosis is endemic.

Enzyme replacement therapy in severe Fabry disease with renal failure: a 1-year follow-up.

We present here the course of clinical response of a 53-year-old haemodialysed Fabry patient who received recombinant human alpha-galactosidase A at a dose of 1 mg/kg every other week over a period of 1 year. The therapy was well tolerated by the patient, who revealed an impressive favourable cutaneous, gastrointestinal, neurological and psychiatric response and a dramatic improvement in his quality of life, but no improvement in cardiac and renal function.
