Solid organ transplant recipients (SOTR) are more likely to develop cutaneous squamous cell carcinoma (CSCC), compared to the general population. This increased incidence is due to several factors including chronic ultraviolet radiation exposure, human papillomavirus (HPV) infection, immunosuppressive medication, among others. Primary prevention is crucial, because not only are cutaneous squamous cell carcinomas more frequent in SOTR, but they are also more aggressive and have therefore a worse prognosis. Newer immunosuppressive drugs are associated with a smaller risk of developing CSCC, but they can have more adverse events, prompting patients to abandon therapy. Concerning treatment options for CSCC, they range from surgery, radiotherapy, and systemic therapy, although there are few studies in SOTR concerning the use of immunotherapy and epidermal growth factor receptor (EGFR) inhibitors [ABSTRACT FROM AUTHOR]

Lyme disease is the tick-borne disease with highest incidence in Europe and North America. Climate change seems to be modifying its geographic distribution, with spreading of endemic areas. Simultaneously, an increasingly number of cases is being diagnosed as the knowledge of its clinical presentations is growing. Most individuals come to the Dermatology visit after a tick bite or with lesions diagnosed as erythema migrans. Other cutaneous clinical presentations, like borrelial lymphocytoma and acrodermatitis chronica atrophicans, are rare. In the presence of a tick bite, doctors should remove it from the body surface and perform clinical vigilance for a period of at least 30 days. Prophylactic antibiotic therapy is not recommended in Europe. Preventive measures as the use of protective clothing in endemic areas should be promoted. The diagnosis of erythema migrans is clinical and first line antibiotic therapy is doxyxycline, which has a high success rate. Serologic tests are essential for the diagnosis of less common cutaneous presentations. Histopathologic examination of skin biopsies also supports the diagnosis. Prompt treatment allows faster and greater improvement, with less irreversible lesions. [ABSTRACT FROM AUTHOR]

Introduction: Partner notification plays a key role in the epidemiological control of the increasingly frequent sexually transmitted infections (STI). Material and Methods: One hundred consecutive patients from the Venereology consultation of the Santa Maria Hospital in Lisbon answered a questionnaire on notification of partners. Results: Forty three of the individuals had a previous history of STI, 25 of which had a previous diagnosis of HIV infection. Sixty-four patients said that they informed their partners about the diagnosis. Of those who did not inform, 50% no longer have contact with the partners and 36% consider that was not important. Regarding partner notification methods: 98% found appropriate to bring a leaflet about the disease to the partners; 72% would agree to give a consultation authorization to the partner, 58% considered that taking the medication directly to the partner would be an option, 58% thought appropriate that the partner's family doctor call them for a consultation; and 42% considered appropriate to send an email or mobile message. Discussion: The high percentage a previous STI diagnosis suggests this is a group of individuals with the highest risk of STI transmission. A high percentage (36%) of those who did not inform the partners felt that it would not be important, which may reveal a failure of communication from the health professional. The method considered the most suitable was passive reporting. Conclusion: It is necessary to improve effective partner notification at it is highly needed to reduce the incidence of STI.

Genital herpes is a sexually transmitted infection with high global prevalence. Atypical clinical presentations of herpetic infection are rare but are becoming increasingly frequent due to the growing number of immunosuppressed patients. Therapy is challenging, with a longer treatment duration being frequently needed and an important resistance rate to the common anti-viral agents. Foscarnet and cidofovir are effective alternatives. In this article we review three atypical cutaneous presentations of herpetic infection, selected by their relevance in clinical practice: hypertrophic lesions, chronic ulcers and herpetic folliculitis.

The cytomegalovirus infection is prevalent in developed countries. The natural history of disease includes three phases: primoinfection (majority is asymptomatic), latency and reactivation. In certain immunosuppressive states, as in the case of transplantation and HIV infection, the virus can reactivate, occurring cutaneous manifestations, of what stands out the occurrence of genital ulcers. In these, co-infection with other etiologic agents is common, particularly with the herpes simplex virus, leading to more severe manifestations and difficulty in the differential diagnosis. In this context, it is relevant to know the pathogenesis of this virus and the diagnostics means available in order to optimize its therapy. [ABSTRACT FROM AUTHOR]

Introduction: Herpes zoster (HZ) is caused by the varicella zoster virus, with an estimated incidence in the general population of 3.64 cases per 1000 person-years. Its incidence increases in older age and immunosuppression states such as infection with the human immunodeficiency virus (HIV) and malignancy. Material and methods: The authors reviewed the literature in order to study the correlation between the diagnosis of HZ and occult malignancy or HIV infection. Results: In most of the studies, the evidence clearly points to the existence of an association between HZ and occult malignancy, however, the flaws of the study designs preclude the extrapolation of guidelines for clinical practice. In developed countries, data suggests that HZ has a predictive value for HIV infection only in individuals belonging to high risk groups. In countries with limited resources for HIV screening, HZ may serve as a sentinel disease to help in the decision of taking the exam, especially in endemic areas. Conclusion: There are few practical recommendations for what complementary investigation should be offered to patients with HZ. It is necessary to conduct more studies to ascertain if the implementation of sometimes complex or invasive complementary examinations is cost-effective. [ABSTRACT FROM AUTHOR]

Non-melanoma skin cancer is the most prevalent malignancy in fair-skinned people and its incidence is increasing. Recently, studies have suggested that antihypertensive drugs may increase the risk of these tumors, particularly hydrochlorothiazide, due to its photosensitizing properties. The Portuguese National Authority for Medicines and Health Products, INFARMED, has issued an alert to healthcare professionals concerning the increased risk of non-melanoma skin cancer in patients exposed to cumulative doses of this drug. However, study results have been heterogeneous and sometimes conflicting. The high incidence of non-melanoma skin cancer and the large number of patients under chronic hydrochlorothiazide therapy may thus have important public health consequences. In this article, the authors review the published evidence and conclude that there may be an association between hydrochlorothiazide use and the risk of non-melanoma skin cancer, but also point out some limitations of the studies in the literature. It is important to promote preventive strategies against sun exposure, regular skin examinations, and individual assessment of the benefits of hydrochlorothiazide use, particularly in patients with previous skin cancer., (Copyright © 2020 Sociedade Portuguesa de Cardiologia.

Nowadays, due to the increasingly frequent migratory circuits in Europe and the increment of the migrant population in Portugal, mainly in the Lisbon metropolitan area, it is more and more common to find several dermatological conditions and disorders in Africans seen in our health care system. There are few studies on dermatoses in these populations. It is important to know the biologic and physiologic differences of black skin in order to understand both the pathophysiology and manifestations of dermatoses. The recognition of many of them represents a challenge to any clinician due to the specific characteristics of their skin. It is thus essential to know the different patterns and frequencies of skin diseases in Africans, in order to optimize the diagnosis, approach and treatment.

Background: Sexual transmitted infections are a main cause of morbidity, being a public health problem due to its reproductive complications, mostly observed in teenagers and young adults. The purpose of this study was to evaluate sociodemographic factors and risky behaviours associated with sexual transmitted infections acquisition and to assess personal awareness of risky behaviour and the knowledge about Chlamydia trachomatis infection between foreign exchange students in Portugal., Material and Methods: The main instrument for data collection was a questionnaire, applied to foreign students in university exchange in Portugal, during the years 2012/2013, 2013/2014 e 2014/2015 Results: Three hundred and thirty eight (338) questionnaires were evaluated, being 58.3% female students, aged between 17 and 30 years old. Mean age for the beginning of the sexual activity was 17.5 years old and the mean number of lifetime sexual partners was 6.9. Concerning the answers given: 11.8% mentioned a sexual relationship with the same gender, 9.5% mentioned that they have never done oral sex and 29% assumed they had practiced anal sex; 82.1% mentioned alcohol/drugs consumption; 21% did not know that Sexual transmitted infections can be transmitted through oral sex and 42.3% did not recognize Chlamydia trachomatis as an Sexual transmitted infections agent., Discussion: Although sexual transmitted infections can affect individuals of all ages, races and sexual orientation, various demographic, social and behavioral factors have revealed influence in their prevalence rates., Conclusion: Despite knowing about sexual transmitted infections, these students maintain sexual risky behaviours, mainly early age for starting sexual activity, multiple sexual partners and the absence of protection during sexual activities.

Introduction: Syphilis is a sexual and vertical transmitted disease. Its incidence is increasing in Europe, particularly, in Portugal., Material and Methods: A descriptive, retrospective study was performed based on positive treponemal tests from January to December 2013, at the Santa Maria Hospital, Lisbon. In-patients and out-patients evaluated in medical appointments and at the emergency department were included. We proceeded to epidemiological characterization, disease classification and definition of risk factors., Results: We obtained a sample of 580 patients, of whom 51 with no clinical data and 45 with false positive serologies were excluded. There was a predominance of male patients (75%) and a mean age of 47 years. Most (59%) had syphilis successfully treated in the past and 3.7% were in follow-up. We recorded 13 primaries syphilis, 71 cases of secondary syphilis, 40 cases of early latent syphilis, 49 unknown duration syphilis and five cases of late latent syphilis. In the early syphilis group, 42% (n = 124) were HIV-positive and, in 8% both diagnosis were done simultaneously., Discussion: We emphasize the high prevalence of syphilis/HIV co-infection in patients with early syphilis, reinforcing the importance of promoting the use of preventive measures. We obtained 11% of patients with late clinical forms, which are notifiable since June 2014, in Portugal. All serological tests for the diagnosis of syphilis have limitations which emphasizes the importance of clinical-laboratory correlation., Conclusion: Syphilis remains an important public health problem. It is necessary to establish education programs, screening and follow-up strategies to reduce their prevalence and to perform more efficient screening of the partners.
