Clinical and Epidemiological Characteristics of Mpox in HIV-Infected and Uninfected Men Who Have Sex with Men: A Retrospective Study in Lisbon.

The resurgence of Mpox, predominantly among men who have sex with men (MSM), has prompted an analysis of its clinical manifestations and epidemiological patterns, particularly in individuals living with human immunodeficiency virus (HIV). This retrospective study aims to delineate and compare the clinical presentations and epidemiological characteristics of Mpox among HIV-positive and HIV-negative individuals. A total of 58 confirmed Mpox cases from a dermatology department in Lisbon were analyzed, focusing on mucocutaneous manifestations, systemic symptoms, and laboratory parameters.

Cumulative incidence and risk factors for cutaneous squamous cell carcinoma metastases in organ transplant recipients: The Skin Care in Organ Transplant Patients in Europe-International Transplant Skin Cancer Collaborative metastases study, a prospective multicenter study.

Introduction: Solid organ transplant recipients (SOTRs) are believed to have an increased risk of metastatic cutaneous squamous cell carcinoma (cSCC), but reliable data are lacking regarding the precise incidence and associated risk factors.

Methods: In a prospective cohort study, including 19 specialist dermatology outpatient clinics in 15 countries, patient and tumor characteristics were collected using standardized questionnaires when SOTRs presented with a new cSCC. After a minimum of 2 years of follow-up, relevant data for all SOTRs were collected.

Monkeypox Diagnosis by Cutaneous and Mucosal Findings.

A monkeypox outbreak has been reported in several countries since early May 2022. Human monkeypox (MPX) diagnosis is based on a clinical suspicion supported by typical skin and mucosal lesions, confirmed with molecular testing. We present the results of all MPX confirmed patients presenting to our department until July 15 of 2022, describing the characteristics of the lesions at diagnosis.

Monkeypox infection and bacterial cellulitis: a complication to look for.

Human monkeypox (MPX) is an endemic zoonotic disease in regions of Africa caused by the monkeypox virus, with recent outbreaks in several non-African countries. In this study, we present two cases of patients with MPX infection complicated by a deep skin infection. Both patients presented to our dermatology clinic with a clinical syndrome characteristic of MPX.

Human monkeypox coinfection with acute HIV: an exuberant presentation.

Human monkeypox (MPX) is a zoonotic endemic disease in regions of Africa caused by the monkeypox virus, with a recent outbreak in several non-African countries. We report a case of a 24-year-old male patient with a concurrent diagnosis of MPX and acute HIV infection who presented to our Emergency Care Dermatology Clinic with disseminated papules throughout the trunk, face and genital area. On the perianal area, several grouped umbilicated whitish papules in a kissing lesion configuration could be seen.

Emerging treatments for bullous pemphigoid.

Bullous pemphigoid (BP) is the most common autoimmune blistering disease. It is characterized by an immune response against the hemidesmosomal anchoring proteins BP180 and BP230. BP mainly affects elderly patients, with an increasing incidence over the past two decades.

Hydrochlorothiazide treatment and risk of non-melanoma skin cancer: Review of the literature.

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.

Acquired perforating dermatosis: clinicopathologic study of a 10-year period at a tertiary teaching hospital.

Background: Acquired perforating dermatosis (APD) comprises an uncommon group of skin disorders that develop in adulthood in association with systemic diseases. The aim of this study was to characterize clinicopathologic features and treatment outcomes in a series of patients diagnosed with APD.

Methods: Retrospective study of all patients diagnosed with an APD over a 10-year period (2009-2018) at a tertiary teaching hospital in Lisbon, Portugal.

Successful Treatment with Fusidic Acid in a Patient with Folliculitis Decalvans.

Dear Editor, Folliculitis decalvans (FD) is a rare form of primary neutrophilic cicatricial alopecia. It is a highly distressing disease that affects young and middle-aged adults, with a slight male predominance (1). The most frequent clinical manifestations are follicular pustules and diffuse and perifollicular erythema that heal with centrifugal scarring.

[Skin Diseases in Africans].

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.

Hepatitis C virus infection: 'beyond the liver'.

There are rare reports of association between hepatitis C virus (HCV) infection and dermatomyositis although cause and effect remains to be proven. We present a clinical case with a probable cause and effect association between these two entities. A 71-year-old woman developed an erythematous exanthem with pruritic and scaly lesions located at the torso and upper limbs associated with heliotrope and Gottron's papules.

Basal cell carcinoma in a 17 year-old organ transplant recipient.

Skin cancer is among the most frequent cancers in pediatric organ transplant recipients. We report a 17-year-old Caucasian girl who had had a kidney transplant 6 years before and was referred to our outpatient clinic for a basal cell carcinoma of the scalp. This case emphasizes the importance of teaching sun-protective behavior to transplant recipients and their parents and having a high index of suspicion and arrange for early referral for dermatologic care if skin changes are observed.

Nonvenereal Penile Dermatoses: A Retrospective Study.

Context: A variety of nonvenereal diseases can affect the penis and diminish quality of life. Many present similar clinical features and a cutaneous biopsy may be necessary to clarify the diagnosis.

Aims: To characterize nonvenereal penile dermatoses with histological confirmation in a southwestern Europe hospital during a 9-year period.

Skin Diseases in the Era of Highly Active Antiretroviral Therapy: A Retrospective Study of 534 Patients.

Background: With the increasing number of HIV-infected patients receiving highly active antiretroviral therapy (HAART), the shift in their dermatologic profile becomes less characteristic of AIDS-defining illnesses.

Methods: Retrospective review of mucocutaneous pathology among patients seen at HIV-Dermatology Clinic from January 2009 to December 2013.

Results: Among 534 patients, there were 68.

Skin disorders in renal transplant recipients: a retrospective study.

Background: Immunosuppressive therapy, which is necessary to avoid graft rejection in renal transplant recipients, presents an increased risk of several pathologies, namely infectious and neoplastic.

Objectives: To identify the most frequent skin diseases and their clinical and demographical risk factors within a population of renal transplant recipients.

Methods: A retrospective study of renal transplant recipients referred to dermatology visit and observed for the first time from January 2008 to December 2014.

[Study of the Sociodemographic Factors and Risky Behaviours Associated with the Acquisition of Sexual Transmitted Infections by Foreign Exchange Students in Portugal].

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.
