Sebocytes differentially express and secrete adipokines.

In addition to producing sebum, sebocytes link lipid metabolism with inflammation at a cellular level and hence, greatly resemble adipocytes. However, so far no analysis was performed to identify and characterize the adipocyte-associated inflammatory proteins, the members of the adipokine family in sebocytes. Therefore, we determined the expression profile of adipokines [adiponectin, interleukin (IL) 6, resistin, leptin, serpin E1, visfatin, apelin, chemerin, retinol-binding protein 4 (RBP4) and monocyte chemoattractant protein 1 (MCP1)] in sebaceous glands of healthy and various disease-affected (acne, rosacea, melanoma and psoriasis) skin samples.

Nijmegen breakage syndrome complicated with primary cutaneous tuberculosis.

Nijmegen breakage syndrome (NBS) is a rare autosomal recessive chromosomal instability syndrome characterized by severe immunodeficiency, growth retardation, microcephaly, a distinct facial appearance, and a high predisposition to lymphoid malignancy. We report a 7-year-old white girl with NBS associated with cutaneous tuberculosis. The patient presented with multiple red-brown, centrally scaring plaques on the leg and had neither pulmonary nor systemic manifestation of tuberculosis.

[Report on erythroderma and scabies infection in connection with two cases of scabies norvegica].

Erythroderma is an inflammation of almost the whole surface of the skin, characterized by erythema, skin infiltration and desquamation. Despite the etiological factors, the generalized inflammation of a large body surface can lead to a life-threatening condition in itself. Parasite infection lies rarely in the background of erythroderma.

[Jellyfish sting. A case report].

Jellyfish bites in Hungary are rare. Yet, from a differential diagnostic point of view this epizoonozis might gain importance given the ever-growing popularity of seaside tourism. A 10 year old female patient was stung by a jellyfish while sea-bathing in the Adriatic in the summer of 2005.

Activation of Notch1 signaling is required for beta-catenin-mediated human primary melanoma progression.

Notch is a highly conserved transmembrane receptor that determines cell fate. Notch signaling denotes cleavage of the Notch intracellular domain, its translocation to the nucleus, and subsequent activation of target gene transcription. Involvement of Notch signaling in several cancers is well known, but its role in melanoma remains poorly characterized.
