[Ramsay Hunt syndrome].

Ramsay Hunt syndrome is a special form of herpes zoster which is typically characterized by peripheral facial palsy and unilateral herpetic vesicles on the ear. These symptoms are often accompanied by vestibulocochlear dysfunction and other neurological and ophthalmological symptoms. The diagnosis and therapy requires a multidisciplinary approach.

Decongestion improves cell-mediated immunity in postmastectomy arm lymphoedema: a pilot study.

Background: Chronic lymphoedematous limbs have an increased propensity for infections and primary or secondary malignant tumours. It has been attributed to suppressed delayed-type hypersensitivity measured in lymphoedemas related to Stewart-Treves syndrome, Kaposi's sarcoma or breast cancer treatment. Cell-mediated immunity is an effective defence mechanism against bacteria, fungi, viruses and tumour cells.

Lipedema: an overview of its clinical manifestations, diagnosis and treatment of the disproportional fatty deposition syndrome - systematic review.

Lipedema is a disproportionate, symmetrical fatty swelling characterized by pain and bruising existing almost exclusively among women. We undertook a systematic review of the available literature about lipedema, given the lack of knowledge and little evidence about this disorder especially among obesity experts. Diagnosis of lipedema is usually based on clinical features.

Switching on RNA silencing suppressor activity by restoring argonaute binding to a viral protein.

We found that Sweet potato feathery mottle virus (SPFMV) P1, a close homologue of Sweet potato mild mottle virus P1, did not have any silencing suppressor activity. Remodeling the Argonaute (AGO) binding domain of SPFMV P1 by the introduction of two additional WG/GW motifs converted it to a silencing suppressor with AGO binding capacity. To our knowledge, this is the first instance of the transformation of a viral protein of unknown function to a functional silencing suppressor.

A newly identified missense mutation of the HR gene is associated with a novel, unusual phenotype of Marie Unna Hereditary Hypotrichosis 1 including limb deformities.

Marie Unna Hereditary Hypotrichosis 1 (MUHH1; OMIM 146550), a rare monogenic condition characterized by the development of sparse, twisted hair or complete hair loss, is the consequence of mutations located in the hairless (HR) gene. We have identified a 68-year-old Hungarian woman affected by alopecia universalis and limb deformities of all four extremities. Direct sequencing of the coding regions of the HR gene revealed a novel missense mutation in the third exon of the HR gene (c.

Successful treatment of multiple basaliomas with bleomycin-based electrochemotherapy: a case series of three patients with Gorlin-Goltz syndrome.

Gorlin-Goltz syndrome is a rare multisystemic disease, characterized by numerous basal cell carcinomas. The ideal approach for patients with the syndrome would be a treatment with a high cure rate, minimal scarring, short healing time and mild side-effects. Electrochemo-therapy is a novel therapeutic option that ablates tumours with electrical current and simultaneously administered anticancer drugs.

Monocyte-derived interferon-alpha primed dendritic cells in the pathogenesis of psoriasis: new pieces in the puzzle.

Psoriasis is a common chronic inflammatory skin disorder with serious clinical, psychosocial, and economic consequences. There is much evidence that different dendritic cell (DC) subsets, various proinflammatory cytokines and Toll-like receptors (TLRs) have a central role in the pathogenesis of the disease. One of the early events in psoriatic inflammation is the secretion of interferon (IFN)-α by activated plasmacytoid DCs, a special DC subset present in symptomless psoriatic skin.

[Allopurinol-induced hypersensitivity syndrome].

Unlabelled: Allopurinol is an effective urate lowering drug, which is usually well-tolerated with no adverse effects in most cases, but about 2% of the treated patients develop a skin rash, and patients may experience severe allopurinol-induced hypersensitivity syndrome.

Aims: The aim of the authors was to summarize and present the clinical manifestations of allopurinol-induced hypersensitivity in patients treated at the Department of Dermatology and Allergology, University of Szeged in order to identify potential associations with this syndrome.

Methods: Retrospective review of all patients who were referred to the department with allopurinol-induced hypersensitivity syndrome in the last four years.

Lymphedema treatment decreases pain intensity in lipedema.

Lipedema is a disproportional obesity featuring light pressure-induced or spontaneous pain. On the basis of our clinical observations, lymphedema therapy, as practiced in our clinic, reduces the perception of pain beyond leg volume reduction. We therefore aimed to measure pain intensity prior and subsequent to treatment.

Mechanisms of IFN-γ-induced apoptosis of human skin keratinocytes in patients with atopic dermatitis.

Background: Enhanced apoptosis of keratinocytes is the main cause of eczema and spongiosis in patients with the common inflammatory skin disease atopic dermatitis (AD).

Objective: The aim of the study was to investigate molecular mechanisms of AD-related apoptosis of keratinocytes.

Methods: Primary keratinocytes isolated from patients with AD and healthy donors were used to study apoptosis by using annexin V/7-aminoactinomycin D staining.

MiR-21 is up-regulated in psoriasis and suppresses T cell apoptosis.

MicroRNAs are short non-coding RNAs that regulate gene expression. Previously, in a genome-wide screen, we found deregulation of microRNA expression in psoriasis skin. MicroRNA-21 (miR-21) is one of the microRNAs significantly up-regulated in psoriasis skin lesions.

Detection of a rare CDKN2A intronic mutation in a Hungarian melanoma-prone family and its role in splicing regulation.

Background: The major locus for melanoma predisposition is the cell cycle regulatory CDKN2A gene on chromosome 9p21. However, the frequency of germline coding mutations of the CDKN2A gene is lower than expected in melanoma-prone families linked to chromosome 9p21.

Objectives: To investigate whether the rare IVS1+37 G/C intronic mutation of the CDKN2A gene, recently identified in a Hungarian melanoma-prone family, influences mRNA splicing regulation.

A novel murine model for the in vivo study of transdermal drug penetration.

Enhancement of the transdermal penetration of different active agents is an important research goal. Our aim was to establish a novel in vivo experimental model which provides a possibility for exact measurement of the quantity of penetrated drug. The experiments were performed on SKH-1 hairless mice.

Genome sequence of Propionibacterium acnes type II strain ATCC 11828.

Propionibacterium acnes is an anaerobic Gram-positive bacterium that forms part of the normal human cutaneous microbiota and is occasionally associated with inflammatory diseases (I. Kurokawa et al., Exp.

The expressions of ABCC4 and ABCG2 xenobiotic transporters in human keratinocytes are proliferation-related.

Xenobiotic transporters of the ATP-binding cassette (ABC) protein superfamily play important roles in maintaining the biochemical barrier of various tissues, but their precise functions in the skin are not yet known. Screening of the expressions of the known xenobiotic transporter genes in two in vitro keratinocyte differentiation models revealed that the ABCC4 and ABCG2 transporters are highly expressed in proliferating keratinocytes, their expressions decreasing along with differentiation. Abrogation of the ABCC4 and ABCG2 protein functions by siRNA-mediated silencing and chemical inhibition did not affect the proliferation of HaCaT cells.

Specific inhibition of the ABCG2 transporter could improve the efficacy of photodynamic therapy.

Photodynamic therapy is based on the selective accumulation of a photosensitizer in tumors, followed by destruction of the target tissue by a light source. Protoporphyrin IX, a well-known photosensitizer, was recently reported as an endogenous substrate for the multidrug transporter ABCG2. We investigated the role of ABCG2 protein in the porphyrin extrusion ability of keratinocytes, with regard to the impact of the specific inhibition of ABCG2 by a non-toxic fumitremorgin C analog, Ko-134, on photodynamic therapy efficacy.

Melanoma and melanocytic nevi in decorative tattoos: three case reports.

Background: In response to the demands of style and fashion, the number of decorative tattoos has been increasing worldwide. This has been paralleled by a rising incidence of melanocytic proliferations, including melanoma. The coincidence of various dermatological diseases and skin tumors with tattoos has been documented with some frequency, but reports of melanoma associated with tattoos are exceedingly rare.

The rs3761548 polymorphism of FOXP3 is a protective genetic factor against allergic rhinitis in the Hungarian female population.

We aimed to study whether forkhead box P3 (FOXP3) polymorphisms contribute to allergic rhinitis (AR) in a Central-European population, the Hungarians, similarly as it was found in Han Chinese. A case-control study was performed and the genotype distribution of the rs3761548 FOXP3 polymorphism was analyzed separately in females and in males. The results demonstrated that females homozygous for the rare FOXP3 rs3761548 allele (A/A) are protected against AR; otherwise, females who are either wild types (C/C) or heterozygote carriers (C/A) of the rare allele are more susceptible to AR (OR [95%CI] = 2.

Comparison of stress-induced PRINS gene expression in normal human keratinocytes and HaCaT cells.

Psoriasis is a chronic inflammatory skin disease that affects approximately 2-4% of the population. We recently described a novel non-coding RNA, psoriasis susceptibility related RNA gene induced by stress (PRINS), that was overexpressed in non-lesional psoriatic epidermis, and its expression was induced by various stress factors such as serum starvation, contact inhibition, ultraviolet (UV)-B irradiation, viral infection and translational inhibition in HaCaT cells. In the present work we set out to compare the stress and microbial agent-induced PRINS expression in normal human keratinocytes (NHKs) and HaCaT cells.
