Abstract
Anaplastic large cell lymphoma (ALCL) is a high-grade non-Hodgkin's lymphoma recognized by the expression of the CD30 marker and by its morphology. We report an unusual case of ALCL in a 42-year-old woman. For ten years the patient only had pruritic erythematous skin lesions, then a plaque with nodules and ulcers on the right thigh and leg developed, followed by ichthyosis acquisita. The development of ALCL in women and the association of ichthyosis acquisita with this type of lymphoma are uncommon.

Abstract
Background Defects in keratinocyte differentiation and skin barrier are important features of inflammatory skin diseases like atopic dermatitis. Mast cells and their main mediator histamine are abundant in inflamed skin and thus may contribute to disease pathogenesis. Methods Human primary keratinocytes were cultured under differentiation-promoting conditions in the presence and absence of histamine, histamine receptor agonists and antagonists. The expression of differentiation-associated genes and epidermal junction proteins was quantified by real-time PCR, Western blot, and immunofluorescence labeling. The barrier function of human skin models was tested by the application of biotin as tracer molecule. Results The addition of histamine to human keratinocyte cultures and organotypic skin models reduced the expression of the differentiation-associated proteins keratin 1/10, filaggrin, and loricrin by 80–95%. Moreover, the addition of histamine to skin models resulted in the loss of the granular layer and thinning of the epidermis and stratum corneum by 50%. The histamine receptor H1R agonist, 2-pyridylethylamine, suppressed keratinocyte differentiation to the same extent as did histamine. Correspondingly, cetirizine, an antagonist of H1R, virtually abrogated the effect of histamine. The expression of tight junction proteins zona occludens-1, occludin, claudin-1, and claudin-4, as well as that of desmosomal junction proteins corneodesmosin and desmoglein-1, was down-regulated by histamine. The tracer molecule biotin readily penetrated the tight junction barrier of skin cultures grown in the presence of histamine, while their diffusion was completely blocked in nontreated controls. Conclusions Our findings suggest a new mechanism by which mast cell activation and histamine release contribute to skin barrier defects in inflammatory skin diseases.

Abstract
BACKGROUND AND PURPOSE In a very limited number of cases, acute migrainous aura may mimic acute brain infarction. The aim of this study was to recognize patterns of MR perfusion abnormalities in this presentation. MATERIALS AND METHODS One thousand eight hundred fifty MR imaging studies performed for the suspicion of acute brain infarction were analyzed retrospectively to detect patients with acute migrainous aura not from stroke. All patients were examined clinically by 2 neurologists and underwent a standard stroke MR imaging protocol, including PWI. Two radiologists reviewed the perfusion maps visually and quantitatively for the presence, distribution, and grade of perfusion abnormalities. RESULTS Among 1850 MR imaging studies, 20 (1.08%) patients were found to have acute migrainous aura. Hypoperfusion was found in 14/20 patients (70%) with delayed rMTT and TTP, decreased rCBF, and minimal decrease in rCBV. In contrast to the typical pattern in stroke, perfusion abnormalities were not limited to a single vascular territory but extended to >1. Bilateral hypoperfusion was seen in 3/14 cases. In 11/14 cases, hypoperfusion with a posterior predominance was found. TTP and rMTT were the best maps to depict perfusion changes at visual assessment, but also rCBF maps demonstrated significant hypoperfusion in quantitative analysis. In all patients, clinical and imaging follow-up findings were negative for stroke. CONCLUSIONS Acute migrainous aura is rare but important in the differential diagnosis among patients with the suspicion of acute brain infarction. Atypical stroke perfusion abnormalities can be seen in these patients.

Abstract
BACKGROUND The objective of this study was to assess the association between melanocortin-1 receptor (MC1R) variants and the severity of facial skin photoaging. METHODS The study population comprised 530 French middle-aged women between 44 and 70 years. A trained dermatologist graded the severity of facial skin photoaging from photographs using Larnier's global scale. Logistic regressions were performed to assess the influence of MC1R polymorphism on severe photoaging (grades 1-3 vs. 4-6), with adjustment for possible confounders (demographic and phenotypic data, and sun exposure intensity). RESULTS Overall, 35% of the women were wild-type homozygotes, 49% had one variant, 15% had two variants, and 1% had at least one rare variant. After adjustment for possible confounders, the presence of two major diminished function variants was found to be a risk factor for photoaging (adjusted odds ratio=5.61; 95% confidence interval [1.43-21.96]). DISCUSSION Our results suggest that genetic variations of MC1R are important determinants for severe photoaging.

Abstract
Hallux valgus represents a combined deformity with malpositioning of the big toe in the metatarsophalangeal joint and metatarsal splaying due to metatarsus primus varus formation. It is defined on the basis of joint condition of the metatarsophalangeal and tarsometatarsal (TMT) joints, the extent and congruence or incongruence of malposition, mobility of the metatarsophalangeal joint and TMT stability. Basic resection appears to be indicated only in exceptional cases. Depending on the degree of severity, deformities can be corrected by means of distal, diaphyseal or proximal osteotomies and TMT arthrodeses. Any correction requires the use of subtle soft tissue surgery with recentering of the tendon, tightening of the medial capsule and abductor hallucis and releasing the lateral capsule. A check-list-like analysis of hallux valgus deformity helps determine the ideal procedure and avoid over- or under-treatment.

Abstract
BACKGROUND Patients with multiple sensitizations require alternative forms of treatment, as the efficacy of conventional immunotherapy is unsatisfactory. OBJECTIVE In the present study, we sought to compare the efficacy of a subcutaneously (s.c.) and a mucosally applied polyvalent vaccine to reduce allergic immune responses within airway and lung tissues. METHODS Female BALB/c mice were intraperitoneally immunized with recombinant (r)Bet v 1, rPhl p 1 and rPhl p 5, followed by an aerosol challenge of birch and phleum pollen extract. For tolerance induction, either a mixture of the immunodominant peptides or a hybrid peptide of the respective antigens was s.c. injected or intranasally applied before poly-sensitization. RESULTS Mucosal but not systemic pre-treatment with poly-peptides led to significant suppression of eosinophils and IL-5 production in bronchoalveolar lavages, as well as IL-5, IL-4, IL-13 and eotaxin levels in lung cell cultures. Lung histology showed a clear reduction of cellular infiltration and mucus production only in intranasally pre-treated mice. In accordance, also the systemic immune response, characterized by IgE-dependent basophil degranulation and IL-4 levels in vitro, was significantly reduced by mucosal antigen application, but only marginally influenced by subcutaneous pre-treatment. Both treatment routes led to up-regulated CTLA4 expression in splenocytes, whereas only after mucosal pre-treatment Foxp3 expression levels were enhanced in lung CD3(+) T cells. Furthermore, intranasal but not subcutaneous application of the peptides enhanced IL-10 levels in the lungs, indicating regulatory mechanisms operating in local tolerance induction. CONCLUSION Mucosal application of peptides is superior to systemic application in preventing both local and systemic poly-allergic T helper2 immune responses, suggesting mucosal tolerance induction as an attractive strategy for the primary and secondary prevention of allergic multi-sensitization and lung pathology.

Abstract
BACKGROUND The modified Ludloff proximal first metatarsal osteotomy is indicated for the surgical correction of moderate-to-severe hallux valgus deformity associated with metatarsus primus varus. We report the intermediate-term results of this procedure. METHODS Ninety-nine patients (111 feet) with a mean age of fifty-six years underwent a modified Ludloff proximal first metatarsal osteotomy and a distal soft-tissue procedure at two institutions for the treatment of a moderate-to-severe hallux valgus deformity. The American Orthopaedic Foot and Ankle Society score and weight-bearing radiographs of the foot were assessed preoperatively and after a mean duration of follow-up of thirty-four months. Clinical and radiographic outcome was also compared between younger and older patients, with the arbitrarily chosen age of sixty years dividing the two groups. RESULTS The mean American Orthopaedic Foot and Ankle Society score improved significantly (p < 0.0001) from 53 points preoperatively to 88 points at the time of the most recent follow-up. The mean American Orthopaedic Foot and Ankle Society score for patients who were sixty years of age or less was significantly higher than that for patients who were more than sixty years of age (91 compared with 83 points; p = 0.0057). The mean hallux valgus angle decreased significantly from 35 degrees preoperatively to 9 degrees at the time of the most recent follow-up (p < 0.0001), and the mean intermetatarsal angle decreased significantly from 17 degrees to 8 degrees (p < 0.0001). All osteotomy sites united without dorsiflexion malunion but with a mean first metatarsal shortening of 2.2 mm. CONCLUSIONS To our knowledge, the present report describes the largest cohort of patients undergoing a modified Ludloff osteotomy for the correction of hallux valgus deformity that has been reported in the literature. Our intermediate-term results demonstrate that the procedure achieves significant correction of moderate-to-severe hallux valgus deformity, significant reduction in forefoot pain, and significant improvement in functional outcome. Patients with an age of sixty years or less appear to have a more favorable outcome.

Abstract
Earlier studies have shown that the antral immune response in Helicobacter pylori infection has a mixed Th1-Th2-T-regulatory profile. After eradication, a chronic inflammation remains in some patients, but a follow-up study with a comprehensive cytokine profile in has not previously been published. Twelve patients with H. pylori positive peptic ulcer disease (five antral and seven duodenal) were enrolled and cytokine gene expressions in antral biopsies were determined (1) at entry, (2) after resolving the ulcer with proton pump inhibitor (PPI) treatment and (3) after eradication. The second endoscopy was performed 4 weeks after ending the PPI treatment, and the third endoscopy was performed after a mean of 10 months after eradication. Inflammation was graded according to the updated Sydney system. Interleukin (IL)1beta, IL8, IL12A, IL18, TNFalpha, IFNgamma, IL4, IL6 and IL10 expression levels were analysed by real-time RT-PCR. Mixed mononuclear and neutrophil infiltrates were seen at entry and after ulcer healing. After eradication, low-grade mononuclear infiltrates were found. The cytokine expression levels after ulcer healing (H. pylori positive gastritis) were not significantly different from the levels at entry (ulcer). After eradication, attenuation of the Th1 cytokines except for TNFalpha and a persisting increase of IL4 levels were observed, whereas the IL10 expression was markedly reduced. The present data did not indicate a specific ulcer promoting cytokine gene regulation profile. However, after eradication a chronic low-grade inflammation was seen with reduced Th1, prolonged Th2 and disappearance of the T-regulatory response.

Abstract
To investigate the physiological basis of salt adaptation in poplar, we compared the effect of salt stress on wood anatomy and auxin physiology of the salt-resistant Populus euphratica and salt-sensitive Populus x canescens. Both poplar species showed decreases in vessel lumina associated with increases in wall strength in response to salt, however, in P. euphratica at three-fold higher salt concentrations than in P. x canescens. The predicted hydraulic conductivity of the wood formed under salt stress decreased in P. x canescens, while in P. euphratica, no significant effects of salt on conductivity and transpiration were observed. The concentration of free indole-3-acetic acid (IAA) decreased under salt stress in the xylem of both poplar species, but to a larger extent in P. x canescens than in P. euphratica. Only salt-treated P. euphratica exhibited an increase in IAA-conjugates in the xylem. Genes homologous to the auxin-amidohydrolase ILL3 were isolated from the xylems of P. euphratica and P. x canescens. For functional analysis, the auxin-amidohydrolase from P. x canescens was overexpressed in Arabidopsis. Transgenic Arabidopsis plants were more resistant to salt stress than the wild-type plants. Increased sensitivity of the transgenic Arabidopsis to IAA-Leu showed that the encoded hydrolase used IAA-Leu as a substrate. These results suggest that poplar can use IAA-amidoconjugates in the stem as a source of auxin to balance the effects of salt stress on auxin physiology.

Abstract
AIM The present study investigates the clinical and radiological mid-term results of the modified Ludloff osteotomy, a proximal metatarsal osteotomy for surgical correction of severe metatarsus primus varus with hallux valgus deformity. METHOD 70 feet in 67 patients from 25 to 78 years (average age 56 years) were included in this prospective study. The patients were evaluated with the American Orthopaedic Foot and Ankle Society (AOFAS) forefoot metatarsophalangeal interphalangeal score, which was used preoperatively and at an average follow-up of 37 +/- 6 months. Weight-bearing foot radiographs were analysed according to AOFAS guidelines and statistical evaluation was made with the Wilcoxon signed-rank test. RESULTS The average AOFAS score improved significantly (p < 0.0001) from 55.2 +/- 15.2 points preoperatively to 86.6 +/- 15.2 points at follow-up. Preoperatively, all patients complained of pain (20.2 +/- 9.6 points) which had improved significantly (p < 0.0001) at the latest follow-up (37.3 +/- 5.7 points). The average hallux valgus angle (HVA) was 37 +/- 8 degrees preoperatively and improved significantly to 12 +/- 11 degrees at follow-up (p = 0.0001). The intermetatarsal angle (IMA) improved significantly from 18 +/- 2 degrees preoperatively to 8 degrees +/- 4 degrees after 37 +/- 6 months (p = 0.0002). The sesamoid position improved significantly from preoperative to follow-up (p = 0.0003). Radiographic evaluation of the patients indicated that all examined osteotomies had healed after 37 +/- 6 months. CONCLUSION This prospective investigation at intermediate follow-up using currently available outcome measures suggests that the Ludloff osteotomy is a suitable procedure for the surgical correction of severe metatarsus primus varus (IMA > 15 degrees ) with hallux valgus deformity.

Abstract
We prospectively evaluated the one- and seven-year results of the Weil osteotomy for the treatment of metatarsalgia with subluxed or dislocated metatarsophalangeal joints in 25 feet of 24 patients. Good to excellent results were achieved in 21 feet (84%) after one year and in 22 (88%) after seven years. The American Orthopaedic Foot and Ankle Society score significantly improved from 48 (sd 15) points before surgery to 75 (sd 24) at one year, and 83 (sd 18) at seven years. The procedure significantly reduced pain, diminished isolated plantar callus formation and increased the patient’s capacity for walking. Redislocation of the metatarsophalangeal joint was seen in two feet (8%) after one year and in three (12%) after seven years. Although floating toes and restricted movement of the metatarsophalangeal joint may occur, the Weil osteotomy is safe and effective.

Abstract
Multiple warts in a 32-year-old-man are reported that developed after tattooing and remaining exclusively confined to that area. The tattooing was done 2.5 years earlier by a professional tattoo artist. It was previously a lesion-free tattoo, but when damaged by sunburn developed multiple skin warts. The ability of a latent virus to induce warts after cutaneous ultraviolet exposure was discussed.

Abstract
BACKGROUND There are currently very few data regarding the role of cell-mediated cytotoxicity in psoriasis. Both cytotoxic T lymphocytes and natural killer (NK) cells mediate cytotoxicity reactions, mainly by two distinct pathways, the perforin/granzyme and the Fas/Fas ligand pathway. OBJECTIVES To study the expression and distribution of perforin, T- and NK-cell subsets in psoriatic lesional and nonlesional skin. METHODS Skin biopsy specimens from both lesional and nonlesional skin of 11 patients with chronic plaque psoriasis and eight healthy controls were analysed by immunohistochemistry. RESULTS We found a significant increase in CD4+ and CD8+ cells in psoriatic lesions compared with nonlesional and healthy skin. The expression of CD16+ NK cells was significantly lower in lesions compared with healthy skin. Perforin expression was significantly enhanced in the epidermis of psoriatic lesions. CONCLUSIONS Perforin expression is upregulated in the epidermis of psoriatic lesions, suggesting a potential role for perforin in the creation of the psoriatic plaque.

Abstract
Fetal bovine serum (FBS) is a common supplement to in vitro culture media. A workshop was organized to discuss whether or not fetuses might suffer when blood is withdrawn, and to discuss serum replacement methods. When bovine fetuses are exposed after slaughter of the dam, they can suffer only if they inflate their lungs with air and increase their blood oxygen to levels compatible with awareness. Preventing fetuses from breathing air or killing them by an efficient method, according to clearly defined safeguards, ensures that fetal blood collection is humane. Since serum is a supplement of unknown composition, which could be contaminated with unwanted factors, there are scientific and safety reasons for omitting FBS from culture media. Several media have been developed in which minimal or no animal derived components are present. Also, different cell types have been adapted to serum-free media. As yet, no standard serum free media are present, and each cell type requires its own medium composition. Among other recommendations, the establishment of a public database with information on cell types and their serum-free medium composition is proposed.

Abstract
BACKGROUND Current evidence suggests that lichen planus is a T-cell-mediated autoimmune disease in which cytotoxic mechanisms have been poorly investigated. OBJECTIVES We investigated the expression of perforin in subpopulations of peripheral blood lymphocytes (PBL) in exacerbation and remission phases of the disease as well as in skin lesions. METHODS We performed a simultaneous detection of perforin (intracellular molecule) and cell surface antigens on PBL by flow cytometry, and skin lesions were investigated by immunohistochemistry. RESULTS The most interesting finding was a significant increase of perforin expression in cytotoxic T lymphocytes (CD3+ perforin+ cells) in the exacerbation phase of disease (P < 0.05), which was mostly located in the CD8+ subpopulation (CD8+ perforin+) (P < 0.01). Using immunohistochemistry we confirmed the infiltration of T lymphocytes in skin lesions, especially of CD4+ and CD8+ phenotypes, compared with uninvolved (P < 0.05) and healthy skin (P < 0.01). The expression of perforin was also significantly higher in lesional skin compared with nonlesional and healthy skin (P < 0.05). CONCLUSIONS Our results clearly show the upregulation of perforin expression in peripheral blood as well as in lesions of patients with lichen planus and therefore suggest an important role for perforin in this autoimmune disease.

Abstract
The frequency of dermatomycoses as well as the spectrum of causative agents in the Rijeka area, northwestern part of Croatia, in the periods before and during the war (1990-1994) and in the postwar period (1995-1999) were analyzed. A total of 20 463 patients with clinically suspected dermatomycoses referred to the Department of Dermatovenerology, Clinical Hospital Center Rijeka, was examined. In the period from 1990 till 1994, 2462 samples were positive, compared with 2250 positive samples during the period from 1995 to 1999. The most frequently isolated dermatophytes were in both periods Trichophyton mentagrophytes and Microsporum canis, followed by Microsporum gypseum, Epidermophyton floccosum, Trichophyton verrucosum and in the first period T. rubrum. An intensive change in composition of the flora was observed in the postwar period, mainly connected to the migration of population from other regions to the Rijeka area. This was demonstrated by a disappearance of T. verrucosum and T. rubrum and by an eruptive occurrence of Trichophyton violaceum. This antropophilic species became third representative in the postwar period, followed by M. gypseum, and E. floccosum. Our data were compared with those obtained in the same area in previous studies, and with results obtained in other countries.

Abstract
Depth of invasion and stage of the disease are well known prognostic indicators in cutaneous melanoma (CM). However, the role of other parameters, such as the variations in cytomorphology of melanocyte tumours, mitotic activity and angiogenesis is still open to question. The aim of this study was to analyse proliferation by mitotic activity index (MAI) and immunostaining of proliferating cell nuclear antigen (PCNA), and the intensity of neovascularization (microvessel density; MVD) in CM clinical stage I in relation to epithelioid, spindle and nevoid cell type, histological type (superficial spreading melanoma and nodular melanoma), Clark's level and Breslow thickness. Finally, the role of all parameters in the prognosis of CM was evaluated. Statistical analysis demonstrated that cytological characteristics of CM correlate only with Clark's level, while histological types correlate with MAI, PCNA and MVD. MAI and PCNA also showed correlation between groups according to Clark's level and Breslow thickness. Finally, tumour cell PCNA was found to correlate with MVD. Survival of patients with CM correlated significantly with MAI. These results suggest that cytological variation, histological type, PCNA and MVD alone are not independent prognostic parameters, whereas MAI is a potentially important prognostic marker in CM.

Abstract
In this study, we have analysed the distribution of HLA class II alleles and the extended haplotype HLA-Cw-B-DRB1-DQA1-DQB1 in Croatian patients with type I and type II psoriasis by hybridization with specific oligonucleotide probes. Type I psoriasis showed a significant association with the DRB1*0701 [P < 0.00001; relative risk (RR) = 5.83], DQA1*0201 (P < 0.00001; RR = 6.12), DQB1*0201 (P = 0.0006; RR = 3.29) and DQB1*0303 alleles (P = 0.0008; RR = 7.51). A negative correlation with type I disease was observed for the DQA1*0102 allele (P = 0.002; RR = 0.26). Type II psoriasis did not show any association with any class II alleles. The extended haplotype HLA-Cw*0602-B57-DRB1*0701-DQA1*0201-DQB1*0201 was present at a significantly higher frequency in type I patients (P < 0.00001; RR = 7.72). However, this haplotype was not detected at all in patients with type II psoriasis. In conclusion, the extended haplotype HLA-Cw*0602-B57-DRB1*0701-DQA1*0201-DQB1*0201 is a risk haplotype for type I disease in the Croatian population. This particular haplotype has not been reported previously in association with psoriasis in any other ethnic groups.

Abstract
The purpose of the present study was to investigate polymorphism of HLA class II haplotypic associations (HLA-DRB1, -DQA1, -DQB1) and DQCAR alleles in 78 Croatian patients with psoriasis. Patients were divided into two groups according to a family history of disease and age of onset: type I (positive family history and early onset) and type II (negative family history and late onset). The difference in frequency of HLA class II haplotypic associations between type I patients and controls was observed for the following combinations: HLA-DRB1*0701, -DQA1*0201, -DQB1*02 (23.6% vs. 7.2%; p < 0.001), HLA-DRB1*0701, -DQA1*0201, -DQB1*0303 (8.5% vs. 1.3%; p = 0.0018) and HLA-DRB1*1601, -DQA1*0102, -DQB1*0502 (2.8% vs. 9.3%; p = 0.06). The difference between type II psoriasis and controls for association: HLA-DRB1*1501, -DQA1*0102, -DQB1*0602 is not significant (20.0% vs. 8.9%; p = 0.06). The significantly higher frequency of DQCAR 113bp and 119bp alleles in patients with type Ipsoriasis is a result of linkage disequlibrium of these alleles with both HLA-DRB1*0701 haplotypic associations. Analysis ofDQCAR alleles in the HLA-DRB1*0701 haplotypic associations in patients with psoriasis vulgaris and matched controls did not reveal any difference in polymorphism of DQCAR alleles. These data suggest that HLA-DRB*0701 haplotypic combinations are associated with type I but not for type II psoriasis in the Croatian population. DQCAR polymorphism is not useful genetic marker to distinguish susceptible HLA class II haplotypic association.

Abstract
OBJECTIVES Knowledge concerning genital Chlamydia trachomatis infections in eastern Europe is scarce. Data on the legal aspects, epidemiology, diagnosis, and treatment of the infection have never been collected, summarised, and presented to the international scientific community. The aim of this study was to present the current situation on the main aspects of chlamydial infections in the countries of eastern Europe. METHODS Written questionnaires concerning legal aspects, epidemiology, diagnosis, and treatment of the infection were distributed among national STI operating administrators as well as researchers who had presented papers at earlier meetings of European chlamydia or STI societies. RESULTS Most of the countries have not legalised reporting of chlamydial infections and in those who have done so, the quality of the reporting system is poor. Contact tracing is mostly done on a voluntary basis. Reported chlamydia incidence varies from 21 to 276 per 100000 inhabitants. The most commonly used diagnostic test remains the direct immunofluorescence test; however, some tendencies towards nucleic acid amplification are in evidence. Diagnostic services are paid for by the patient himself, while treatment in many countries is partially or completely covered by public insurance. CONCLUSIONS This is the first report summarising data concerning the situation on C trachomatis infections in eastern Europe. The reporting system and diagnosis of C trachomatis infections remain suboptimal, which allows neither control of the epidemiological situation nor optimal treatment of the patients. The most urgent work currently necessary is the education of professionals and the general population.
