Abstract
BACKGROUND In the era of precision medicine, identification of possible predictive factors of clinical response to treatment is fundamental. This need is particularly strong for anogenital warts (AGW), because there are several treatment modalities with different clearance and recurrence rates. However, data regarding the effect of mental health parameters on response to treatment in patients with AGW are lacking. OBJECTIVES The purpose of the present study was to evaluate the association between patients' mental health parameters and AGW treatment outcomes. METHODS This was a single-centre, prospective study that included newly diagnosed male patients with AGW. At their initial visit, all patients completed the State-Trait Anxiety Inventory (STAI), the Symptom Checklist-90-Revised (SCL-90-R) and the Eysenck Personality Questionnaire (EPQ) questionnaires, which evaluate anxiety, psychopathological manifestations and personality traits, respectively. All patients received cryotherapy until clearance of lesions and were followed up for 18 months for detection of recurrences. RESULTS The study included 167 male patients. The mean number of days for AGW clearance was 89 ± 65. During the 18-month follow-up, 28% of participants showed a recurrence, after a mean number of 150 ± 132 days. No statistically significant association was detected between questionnaires scores and (a) time needed for AGW clearance, (b) time until 1st recurrence and (c) number of recurrences. CONCLUSION If confirmed, our findings indicate that we may not need to modify our AGW treatment plan according to a patient's mental health profile.

Abstract
BACKGROUND Anogenital warts (AGW) can cause economic burden on healthcare systems and are associated with emotional, psychological and physical issues. OBJECTIVE To provide guidance to physicians on the diagnosis and management of AGW. METHODS Fourteen global experts on AGW developed guidance on the diagnosis and management of AGW in an effort to unify international recommendations. Guidance was developed based on published international and national AGW guidelines and an evaluation of relevant literature published up to August 2016. Authors provided expert opinion based on their clinical experiences. RESULTS A checklist for a patient's initial consultation is provided to help physicians when diagnosing AGW to get the relevant information from the patient in order to manage and treat the AGW effectively. A number of frequently asked questions are also provided to aid physicians when communicating with patients about AGW. Treatment of AGW should be individualized and selected based on the number, size, morphology, location, and keratinization of warts, and whether they are new or recurrent. Different techniques can be used to treat AGW including ablation, immunotherapy and other topical therapies. Combinations of these techniques are thought to be more effective at reducing AGW recurrence than monotherapy. A simplified algorithm was created suggesting patients with 1-5 warts should be treated with ablation followed by immunotherapy. Patients with >5 warts should use immunotherapy for 2 months followed by ablation and a second 2-month course of immunotherapy. Guidance for daily practice situations and the subsequent action that can be taken, as well as an algorithm for treatment of large warts, were also created. CONCLUSION The guidance provided will help physicians with the diagnosis and management of AGW in order to improve the health and quality of life of patients with AGW.

Abstract
BACKGROUND Epidemiological data on primary syphilis in Greece are limited. OBJECTIVE The purpose of the present study was to investigate the trends of the disease in Greece during the last few years and whether they are in accordance with the trends in other European countries and the United States of America. METHODS We conducted a retrospective analysis based on records of patients who visited the Sexually Transmitted Infections Unit of 'A. Sygros' Hospital in Athens, Greece, during the period 2005-2012. Our hospital is a tertiary referral centre for sexually transmitted infections covering an area of more than four million people, which is almost half the population of Greece. We documented the total annual number of patients, the male to female ratio, sexual orientation, patients' ethnic origin and education level. RESULTS We reviewed the records of 1185 patients with a confirmed diagnosis of primary syphilis. The total number of patients with primary syphilis has risen from 111 in 2005 to 158 in 2012, an increase of 42.3%. The mean annual number is 148. The mean male to female ratio is 4.76 : 1, with a peak value of 8.50 : 1 in 2011. The majority of patients are of Greek origin, ranging from 67.4% to 87.2%. Within the male patients group, it seems that the percentage of men having sex with men has risen steadily from 2005 (20.7%) up to 2010 (59.1%) with a decline in 2012 (46.0%). The mean value over 8 years is 45.0%. CONCLUSION Primary syphilis in Greece is on the rise. Τhe majority of our patients are Greek, despite immigrant influx. Men clearly outnumber women, representing more than 80% of the total number of patients. Furthermore, there seems to be a trend towards predominance of men having sex with men as the core group among male patients.

Abstract
Vitiligo is a disorder of depigmentation, for which the pathogenesis is as yet unclear. Interleukin (IL)-8 (CXCL8) is a key inflammatory chemokine. We investigated the regulation of IL-8 production in human melanocytes, and the IL-8 serum levels and skin gene expression in patients with vitiligo and in controls. Cultured melanocytes were stimulated for 24 h with tumour necrosis factor (TNF) 100 ng/mL and IL-1β 10 ng/mL, with or without pretreatment with luteolin 50 μmol/L for 30 min, and IL-8 release was measured by ELISA. Serum cytokines were measured by a microbead array. Skin biopsies were taken from healthy subjects (n = 14) as well as from marginal lesional and nonlesional skin from patients with vitiligo (n = 15). IL-8 gene expression was evaluated by quantitative real time PCR. Both TNF and IL-1β stimulated significant IL-8 release (P < 0.01) from melanocytes, whereas pretreatment with luteolin significantly inhibited this effect (P < 0.01). IL-8 gene expression was significantly increased in vitiligo compared with control skin (P < 0.05). IL-8 may be involved in vitiligo inflammation. Inhibition by luteolin of IL-8 release could be useful for vitiligo therapy.

Abstract
Giant condyloma acuminatum (GCA), or Buschke–Löwenstein tumour (BLT), is a rare large tumour of the anogenital area. It is caused by human papillomavirus genotypes 6 and 11, and it is characterized by aggressive local invasion and frequent recurrences after treatment. Treatment of choice is radical excision, although chemotherapy and radiation are also used in special cases. We report a case of a young man with anogenital GCA, presenting with a large perianal mass and pain during defaecation. The patient was treated by surgical removal of almost the entirety of the mass, using radiofrequency surgical dissection. The concurrent use of oral acitretin for the treatment of erythrodermic psoriasis led to elimination of the remaining disease. The patient remains free of disease 26 months after the end of treatment.

Abstract
Vitiligo is a cutaneous disorder of depigmentation, clinically characterized by well-demarcated, white macules of varying size and distribution. It can affect up to 2% of the population, especially younger ages. In spite of recent findings implicating genetic, immune and oxidative stress factors, the exact pathogenesis of vitiligo remains obscure. Here, we briefly discuss the prevailing theories, and offer new suggestions that could explain in part the damage of melanocyte in the vitiliginous lesions. Our emerging hypothesis is that neuropeptides released from peripheral nerve endings could synergize with new cytokines to adversely affect melanocyte function and viability. These may include corticotropin-releasing hormone (CRH) and neurotensin (NT), as well as interleukin 33 (IL-33) and thymic stromal lymphopoietin (TSLP). Such interactions could serve the basis for further research, possibly leading to new treatments.

Abstract
Merkel cell carcinoma is a rare but aggressive neuroendocrine carcinoma of the skin with a rising incidence and a high mortality rate. It occurs primarily in sun-exposed skin of older individuals. It is characterized by a high rate of local recurrence, regional lymph node metastases and distant metastases, occurring even after prompt treatment. Many controversies exist regarding its pathogenesis and optimal management. The discovery of Merkel cell polyomavirus has been a major breakthrough in understanding the aetiology of the disease. A recently adopted new international consensus staging system in combination with new international diagnostic codes are expected to facilitate future clinical trials and improve the management of patients. According to recent (2010) guidelines, most patients should be managed with a combination of surgery and radiotherapy.

Abstract
Epidermolysis bullosa acquisita (EBA) is a rare autoimmune bullous disorder that is often difficult to treat. Few cases have been reported and therapy consists mainly of combinations of systemic steroids, immunosuppressants and, recently, administration of intravenous human immunoglobulin (IVIg). We describe a case of EBA in which our therapeutic choices were limited due to the patient's poor general condition, including extensive infection of the lesions and a history of pulmonary tuberculosis. The patient was treated with IVIg at a dose of 400 mg/kg per day for 5 consecutive days every 4 weeks. The treatment was well tolerated and the results were satisfactory. It seems that IVIg, due to its possible immunomodulatory mode of action, can be an efficacious therapeutic agent in this rare autoimmune disease.

Abstract
Cutaneous larva migrans (CLM) is a characteristic eruption that is caused by penetration and migration in the skin of nematode larvae. Both animal and human hookworms have been implicated in the pathogenesis of the condition, with Ancylostoma braziliensis and A. caninum being the most common among them. CLM is quite common in tropical areas, but, due to travelling, several cases have also been described in Europe. We present a patient with CLM who presumably contacted the disease during a holiday in Singapore. The patient was treated successfully with oral thiabendazole.

Abstract
BACKGROUND Antithrombin III (AT-III) is a physiological inhibitor of thrombin and other serine proteases, and has antiinflammatory properties. Thrombin is known to enhance T lymphocyte activation in vitro and serine proteases can act as costimulators for lymphocyte proliferation and cytokine production. We have previously shown that AT-III significantly inhibited allograft rejection in a highly histoincompatible model of rat lung transplantation and in vitro cell proliferation in ConA-stimulated rat spleen cells. In this study, we examined the involvement of cytokine gene expression in the above inhibitory effect of AT-III. We also examined the effect of AT-III on several in vitro immune reactions in human peripheral blood mononuclear cells (PBMCs). METHODS mRNA expression of cytokines/cytokine receptor important in lymphocyte activation was examined. Rat spleen cells were stimulated with Con-A with/without AT-III and submitted for reverse transcriptase-polymerase chain reaction (RT-PCR). To assess the effect of AT-III on human PBMCs, we examined the effects of AT-III on cell proliferation of human PBMCs stimulated in mixed lymphocyte reaction (MLR) (allogeneic stimulation), with OKT3 (T cell receptor activation) and with PHA (mitogenic stimulation). The effect of AT-III on PWM-stimulated immunoglobulin (Ig) production by human PBMCs was also examined. All experiments for cell proliferation were performed in 10% serum and in serum-free (SF) media to determine whether AT-III exerted its effects through its interaction with thrombin in serum. RESULTS mRNA expression of IL-2, gamma-IFN and IL-4 in ConA-stimulated rat spleen cells was nearly completely inhibited by AT-III at 15 IU/ml. mRNA levels for IL-6, IL-2R and TGF-beta1 were not significantly affected by AT-III. AT-III showed a dose-dependent inhibition of cell proliferation in human PBMCs. At 15 IU/ml, cell proliferation was inhibited by approximately 86%, approximately 81% and approximately 56% in the MLR-, OKT3- and PHA-stimulated PBMCs, respectively in both serum and SF media. AT-III inhibited PWM-stimulated Ig production in a dose-dependent manner. IgG, IgM and IgA production was reduced by approximately 60%, 80% and 70%, respectively in cultures incubated with 15 IU/ml AT-III. CONCLUSIONS (1) Inhibition of IL-2, gamma-IFN and IL-4 mRNA expression might be responsible for inhibition of cell proliferation by AT-III in ConA-stimulated rat spleen cells, (2) AT-III inhibits cell proliferation in the MLR-, OKT3- and PHA-stimulated human PBMCs, and Ig production in PWM-stimulated human PBMCs, (3) The immune regulatory effects of AT-III are independent of its interaction with thrombin since similar levels of suppression were seen in SF media, and (4) These results suggest that AT-III has potent inhibitory effects on lymphocyte activation and cytokine production and may have potential applications as an immunomodulatory agent.

Abstract
BACKGROUND The ability to express genes with potential immunoregulatory capacity could reduce the immunogenicity of allografts and result in long-term graft survival. In this study, we examine the feasibility of transferring viral interleukin-10 (vIL-10) gene into rat hearts using adenovirus by intracoronary administration. The subsequent effects of delivered vIL-10 alone or with subtherapeutic doses of cyclosporine A (CsA) on parameters of allograft rejection (AR) were also examined. METHODS Recombinant adenovirus vectors containing vIL-10 (Ad-vIL-10) or beta-galactosidase (Ad-beta-gal) were derived from adenovirus type 5. vIL-10 expression in supernatants of transfected COS7 cell cultures and in transfected heart allografts were examined by enzyme immunoassay (EIA) and reverse transcriptase-polymerase chain reaction (RT-PCR), respectively. Rat heart transplants (LEWS->ACI) were performed in five groups [group 1: no treatment, group 2: Ad-beta-gal, group 3: AdvIL-10, group 4: CsA (10 mg/kg), and group 5: Ad-vIL10+CsA (10 mg/kg)]. Allograft survival was determined by palpating heartbeats. Allograft tissues were also submitted for histological study. RESULTS vIL-10 expression was shown in both transfected COS7 cells and heart isografts. Animals transfected with vIL-10 showed prolongation of graft survival (19.6 vs. 12 days, P<0.001) when compared to beta-gal transfected controls. Animals treated with a single low dose injection of CsA showed no significant prolongation of graft survival compared to controls (11.7 vs. 10.5 days). Animals treated with both vIL-10 and CsA demonstrated a synergistic prolongation of allograft survival compared with controls and with animals treated with CsA or vIL-10 treatment alone (36.7 days vs. 11.7, P<0.001 or 36.7 vs.19.6, P<0.001, respectively). Histological study showed that allografts from untreated controls exhibited extensive AR with loss of graft architecture by day 7 posttransplant while those from the vIL-10 group showed less AR. The best pathological scores were seen in vIL-10 + CsA-treated animals. CONCLUSIONS 1) Delivering Ad-vIL-10 into donor hearts by intracoronary perfusion results in overexpression of vIL-10 and significantly prolongs cardiac allograft survival in a highly histoincompatible rat model. 2) Subtherapeutic doses of CsA do not prolong allograft survival, but act synergistically with vIL-10 to significantly prolong graft survival beyond that achieved with either agent alone.

Abstract
BACKGROUND We have reported previously that F344 rats develop a spontaneous tolerance to WKY lung allografts and show long-term retention of donor-specific skin grafts placed 35 days after lung transplantation. In this study, we investigated the immunologic mechanisms that may be responsible for the prolonged skin graft survival in animals tolerized with lung allografts. METHODS In the rejection group, WKY skin grafts were placed on normal F344 rats, whereas, in the tolerance group, the skin grafts were placed on F344 rats that had received a WKY lung transplant 35 days before skin grafting. Th1 (interleukin [IL]-2 and interferon-gamma [IFN-gamma]) and Th2 (IL-4 and IL-10) cytokine as well as transforming growth factor-beta1 mRNA expression in skin grafts and in draining lymph nodes were determined by reverse transcription-polymerase chain reaction. Macrophage and lymphocyte infiltration in skin grafts and the number of Langerhans cells in epidermal sheets of the grafts were examined by immunohistochemistry. RESULTS IL-2 and IFN-gamma mRNA expression was significantly decreased in both the skin grafts and the draining lymph nodes of the tolerance group, compared to the rejection group, whereas IL-10 and transforming growth factor-beta1 mRNA expression was similar in both groups and IL-4 mRNA was rarely detected. Decreased and delayed CD8+, macrophage, and natural killer cell infiltration in the skin grafts from the tolerance group was also detected. Similar reduction in the number of Langerhans cells in the epidermis of the grafts from both groups was seen on day 1 after skin grafting, and thereafter the number remained stable in both groups. CONCLUSIONS Reduced expression of Th1 cytokines and decreased infiltration of CD8+ cells, macrophages, and natural killer cells in the skin grafts may be responsible for prolongation of skin graft survival in the tolerance group.

Abstract
Various cytokines are upregulated in acute allograft rejection (AR). Local production of Th-1 cytokines is suggested to play a pathogenic role in AR, and Th-2 cytokines in the development of allograft tolerance. The purpose of this study was to correlate the expression of Th-1 [interleukin-2 (IL-2) and gamma-interferon (gamma-IFN)], and Th-2 [interleukin-10 (IL-10)] cytokines in bronchoalveolar lavage (BAL) fluid with AR in lung transplant (LT) recipients. The role of Th-1 dominance expressed as IgG2/IgG1 ratio in BAL in AR was also examined. The mRNA expression for IL-2, gamma-IFN and IL-10 was examined in 64 BAL specimens from 23 LT recipients using reverse transcriptase-polymerase chain reaction (RT-PCR). IgG1 and IgG2 levels were measured in 55 BAL specimens by enzyme-linked immunosorbent assay (ELISA). The expression on mRNA for these cytokines, and the ratio of IgG2/IgG1 was correlated with AR (early AR occurring within 3 months of transplant and late AR occurring after 3 months). Ten patients had 17 episodes of biopsy proven AR. Twelve episodes of AR (6 patients) occurred within the first 3 months of transplantation. In 5 patients, AR was diagnosed 4, 5, 6, 9 and 24 months post-transplantation. Detection of gamma-IFN mRNA correlated significantly with early AR (p < 0.001), whereas it lacked correlation with late AR. Expression of IL-2 and IL-10 mRNA did not correlate with AR. IL-10 was present in most samples irrespective of the presence or absence of AR. The ratio of IgG2/IgG1 was similar in patients with or without AR. Our findings suggest that the detection of gamma-IFN mRNA in BAL by RT-PCR is useful for immune monitoring of early AR in LT recipients. Absence of elevated IgG2/IgG1 ratio, and presence of IL-10 in BAL during AR suggests that Th-1 cytokines may not be the sole mediator of rejection in LT recipients.

Abstract
BACKGROUND Antithrombin III (AT-III) is an antithrombotic agent with known anti-inflammatory properties that is also known to attenuate acute inflammation, prevent ischemia-reperfusion injury, and disseminated intravascular coagulation (DIC) associated with sepsis and endotoxemia. Here, we examined the ability of AT-III to modify parameters of acute inflammation in a highly histoincompatible model of rat lung allograft rejection (AR). METHODS After left single lung transplantations (BN-->Lew), recipient animals were treated i.v. with 50 U/kg of human AT-III (low dose group), 500 U/kg of human AT-III (high dose group), or normal saline (control group) on days 2 and 4 posttransplant. All animals were sacrificed on day 6, and several pathological categories of acute inflammation related to AR were scored (0-4). The effect of AT-III on concanavalin A (Con A)-stimulated rat spleen cell proliferation was also examined. RESULTS The stage of AR, and the degrees of edema, hemorrhage, and necrosis were significantly reduced in the high dose group compared with the control group. AT-III significantly inhibited rat spleen cell proliferation in response to Con A, in a dose-dependent manner. Maximal inhibition was seen at 15 U/ml in culture. Identical inhibition of Con-A-stimulated cultures occurred in both serum free and serum-containing media, indicating that AT-III inhibition of Con-A-stimulated rat spleen cell proliferation is independent of its actions on thrombin. CONCLUSIONS 1) AT-III treatment significantly improves parameters of acute inflammation seen in a highly histoincompatible model of rat lung AR. 2) AT-III inhibits in vitro T cell proliferation to the potent mitogen Con A, suggesting that protease inhibition may inhibit T cell activation in vitro. 3). The beneficial effects of AT-III on parameters of lung AR relate to the anti-coagulant, anti-inflammatory, and possibly immunoregulatory actions of AT-III.

Abstract
BACKGROUND The rapidly increasing incidence of cutaneous malignant melanoma in white populations world-wide stresses the need for identification of risk factors for the disease. The most important risk factor seems to be sun exposure, but its relationship to melanoma appears to be complex. OBSERVATIONS Epidemiological studies that examine the association of sun exposure with melanoma are reviewed. The results of these studies concern the anatomic distribution of the disease and its incidence with regard to latitude of residence, sun sensitivity, different patterns of sun exposure, and sun exposure in childhood. CONCLUSIONS Sun-sensitive individuals, children, and individuals with an intermittant pattern of sun exposure seem to be very vulnerable to sunlight, as far as melanoma formation is concerned, and should be thoroughly protected from sun exposure.
