RESUMO

BACKGROUND: Since May 2022, a new outbreak of monkeypox has been reported in several countries, including Spain. The clinical and epidemiological characteristics of the cases in this outbreak may differ from those in earlier reports. OBJECTIVES: To document the clinical and epidemiological characteristics of cases of monkeypox in the current outbreak. METHODS: We conducted a prospective cross-sectional study in multiple medical facilities in Spain to describe the cases of monkeypox in the 2022 outbreak. RESULTS: In total, 185 patients were included. Most cases started with primarily localized homogeneous papules, not pustules, in the probable area of inoculation, which could be cutaneous or mucous, including single lesions. Generalized small pustules appeared later in some of them. Heterogeneous lesions occurred during this generalized phase. All patients had systemic symptoms. Less common lesions included mucosal ulcers (including pharyngeal ulcers and proctitis) and monkeypox whitlows. Four patients were hospitalized, none died. Smallpox vaccination and well-controlled HIV disease were not associated with markers of severity. Contact during sex is the most likely mechanism of transmission. In this outbreak, cases have been described in men who have sex with men and are strongly associated with high-risk sexual behaviours. Seventy-six per cent of the patients had other sexually transmitted diseases upon screening. CONCLUSIONS: The clinical findings in this outbreak differ from previous findings and highly suggest contact transmission and initiation at the entry site. The characterization of the epidemiology of this outbreak has implications for control. What is already known about this topic? Monkeypox eruption is described as consisting of pustules. The roles of HIV and previous smallpox vaccination in the prognosis are unknown. The transmission route was initially described as respiratory droplets and was later suggested to be via sexual contact. What does this study add? Initial lesions at the probable inoculation area were homogeneous and papular (pseudopustules). Generalized small pustules appeared later in some of them. Heterogeneous lesions occurred during this generalized phase. All patients had systemic symptoms. Less common signs included mucosal ulcers (including pharyngeal ulcers and proctitis) and monkeypox whitlows. Well-controlled HIV and previous smallpox vaccination were not associated with severity. No patient died. The data support the hypothesis of transmission via contact during sex. Although this might change, the outbreak is currently limited mostly to men who have sex with men, with high-risk factors for sexually transmitted diseases.

RESUMO

Photodynamic therapy (PDT) is a clinical modality of photochemotherapy based on the accumulation of a photosensitizer in target cells and subsequent irradiation of the tissue with light of adequate wavelength promoting reactive oxygen species (ROS) formation and cell death. PDT is used in several medical specialties as an organ-specific therapy for different entities. In this review we focus on the current dermatological procedure of PDT. In the most widely used PDT protocol in dermatology, ROS production occurs by accumulation of the endogenous photosensitizer protoporphyrin IX after treatment with the metabolic precursors 5-methylaminolevulinic acid (MAL) or 5-aminolevulinic acid (ALA). To date, current approved dermatological indications of PDT include actinic keratoses (AK), basal cell carcinoma (BCC) and in situ squamous cell carcinoma (SCC) also known as Bowen disease (BD). With regards to AKs, PDT can also treat the cancerization field carrying an oncogenic risk. In addition, an increasing number of pathologies, such as other skin cancers, infectious, inflammatory or pilosebaceous diseases are being considered as potentially treatable entities with PDT. Besides the known therapeutic properties of PDT, there is a modality used for skin rejuvenation and aesthetic purposes defined as photodynamic photorejuvenation. This technique enables the remodelling of collagen, which in turn prevents and treats photoaging stygmata. Finally we explore a new potential treatment field for PDT determined by the activation of follicular bulge stem cells caused by in situ ROS formation.

RESUMO

BACKGROUND: Eyelashes play a crucial role in self-image and ocular protection. Enhancements to their structure are of both cosmetic and clinical interest. AIMS: To assess the efficacy of a peptide and glycosaminoglycan-based eyelash enhancer serum in improving eyelash structure. PATIENTS/METHODS: This open-label clinical trial involved 30 females aged 25-65. Eyelashes were assessed at baseline (D0), 4 weeks (D28), and 12 weeks (D84) using specialized software and high-resolution imagery. Measurements included lash number, width, length, volume, arc, and angle. RESULTS: At 12 weeks, significant increases were observed in lash length (+8.3%), number (+5%), width (+10.1%), volume (+14.1%), arc (+13.4%), and angle (+28.3%) compared to baseline. Global Eyelash Assessment (GEA) scores significantly improved, and patient treatment satisfaction increased from 73.34% at D28 to 84.33% at D84. No adverse effects were reported. CONCLUSIONS: The eyelash growth enhancer serum demonstrated significant efficacy in improving eyelash structure by Week 12, with early signs of improvement evident by Week 4. The high patient satisfaction levels underscore the perceived effectiveness of the product.

RESUMO

Smoking has been considering a crucial factor in promoting skin and systemic aging that is associated with the development of a low-level, systemic, chronic inflammation known as "inflammaging" in which monocytes play a pivotal role. Our aim was to investigate the effects of AM3 plus antioxidants vs placebo in the activation status, function of monocytes and cutaneous aging parameters in healthy smoker middle-aged women. A total of 32 women were 1:1 randomly assigned to AM3 plus antioxidants or placebo for three months. Peripheral mononuclear blood cells and cutaneous biopsy were obtained and flow cytometry and immunohistological studies, respectively, were performed before and after the treatment. AM3 plus antioxidants treatment compared with placebo significantly reduced the monocyte production of the proinflammatory interleukin 1 (IL-1), tumor necrosis factor α (TNF-α) and interleukin 6 (IL-6) cytokines as well as increased the regulatory IL-10 in middle-aged smoker women. Furthermore, AM3 and antioxidants did not modify ROS production by monocytes and granulocytes but increased their phagocytic activity. The active combination also stimulated a significative increase in reticular dermis depth as well as an increase in the expression of CD117 and CD31. Thus, AM3 and antioxidants treatment reduces the systemic proinflammatory monocyte disturbance of heathy smoker middle-aged women and encourage skin repair mechanisms.

RESUMO

The proper functioning of the immune system depends on an appropriate balance between pro-inflammation and anti-inflammation. When the balance is disrupted and the system is excessively biased towards inflammation, immune responses cannot return within the normal range, which favors the onset of diseases of autoimmune or inflammatory nature. In this scenario, it is fundamental to find new compounds that can help restore this balance and contribute to the normal functioning of the immune system in humans. Here, we show the properties of a fungal compound with a strong safety profile in humans, AM3, as an immunomodulatory molecule to decrease excessive cytokine production in human cells. Our results present that AM3 treatment of human peripheral blood mononuclear cells and monocytes decreased their pro-inflammatory cytokine secretion following the challenge with bacterial lipopolysaccharide. Additionally, AM3 skewed the differentiation profile of human monocytes to macrophages towards a non-inflammatory phenotype without inducing tolerance, meaning these cells kept their capacity to respond to different stimuli. These effects were similar in young and elderly individuals. Thus, the fungal compound, AM3 may help reduce excessive immune activation in inflammatory conditions and keep the immune responses within a normal homeostatic range, regardless of the age of the individual.

RESUMO

We describe the first 25 persons with HIV diagnosed with human monkeypox virus (MPXV) in our hospital in an ongoing outbreak in Spain. Proctitis was the predominant finding in 52%, and MPXV DNA was detected in rectal swabs from 90%. Proctitis and demonstration of MPXV in rectal swabs support the sexual transmission of MPXV.

RESUMO

Background: A global outbreak of the human monkeypox virus (HMPXV), first identified in May 2022, was declared a health emergency of international concern on 23 July 2022. Before the global outbreak, monkeypox cases were mostly confined to central and west African countries, where this virus is prevalent. Close contact, mainly sexual contact, is supposed to be the main route of transmission, and it is remarkable that the incidence is higher in men who have sexual relationships with other men. Case summary: A 40-year-old Caucasian man arrived at the emergency department complaining of oppressive epigastric pain extending to the chest after a diagnosis of pharyngitis, which was suspected to be caused by the human monkeypox virus. Based on the clinical symptoms, physical examination, serum cardiac biomarkers, and electrocardiographic findings, he was diagnosed with myopericarditis. The real-time PCR for human monkeypox in skin lesions, urine, plasma, and the oropharyngeal swab was positive. The peak of troponin I was 20.6 ng/ml, and the electrocardiogram showed an upward concavity in the ST segment in diffuse leads, which was in agreement with the previous diagnosis. The presence of edema, subepicardial, and myocardial late gadolinium enhancement, and increased values on T1 mapping in the cardiac MRI were in agreement with the diagnosis of myopericarditis. Antiviral treatment with tecovirimat was started with excellent tolerability. After 6 days, the patient recovered and was discharged. Discussion: To our knowledge, this is one of the first reported cases of myopericarditis due to human monkeypox infection, which was confirmed by a cardiac MRI following modified Lake Louise criteria. The short span between the onset of the mucocutaneous symptoms and the myocardial damage suggests a pathogenic association. Furthermore, the active viral replication in plasma samples and the negative results on real-time PCR for other viruses support this clinical association.

RESUMO

BACKGROUND: Ablative fractional laser generates a regulated skin damage, which secondarily improves skin aging. AIMS: The main objective of the present study was to figure out if the adverse effects induced by laser and the skin recovery could improve with the application of a cosmetic product based on the secretion of Cryptomphalus aspersa (SCA). PATIENTS/METHODS: A prospective double-blind controlled study with vehicle in 10 patients with skin aging. The patients received one session of fractional ablative CO2  laser, and the formulation with SCA 40% was applied immediately and maintained throughout the 21-day duration of the study. The active treatment (SCA) was applied to one hemifacial area and vehicle to the other, and the patient acting was her own control. Clinical evaluations, dermoscopy, photography, and other parameters like cutaneous hydration, elasticity, and wrinkles were evaluated. In addition, the severity of the adverse effects was evaluated. RESULTS: Significant greater decrease in the density of microcolumns produced by laser was detected on the active-treated side, indicating greater and faster postprocedure recovery compared to the vehicle-treated side. In addition, side effects were reduced and some antiaging effects were more apparent on the side treated with SCA 40%. CONCLUSION: SCA 40% applied immediately after ablative laser, and during the next days, it can accelerate laser-induced damage regeneration. In addition, SCA improves the cosmetic outcome after laser application.

RESUMO

Lymphomatoid papulosis type E (LyP) is a recently described subtype of LyP characterized by an angioinvasive infiltrate of atypical lymphocytes expressing CD30. We present a case of type E LyP with extensive cutaneous necrosis in the histopathological evaluation which was misdiagnosed as an ulcerative form of bacterial skin infection. The remarkable cutaneous necrosis showed in our case might be related to the angiodestructive infiltrate that was present in this circumstance.

RESUMO

INTRODUCTION: Frontal fibrosing alopecia (FFA) is a condition that likely involves an interplay of autoimmune, hormonal, and environmental factors in its pathogenesis. There is a lack of comparative studies demonstrating the presence of hormonal background differences in FFA patients compared to the general population. MATERIALS AND METHODS: A single-center case-control study was designed, including 104 female FFA patients and 208 controls. Patients and controls were interviewed, and extensive data regarding their gynecological and hormonal background were recorded. RESULTS: One hundred four cases and 208 age-matched controls were included in the study. A significant difference of 2 years in the age of menopause was detected with a consistent mean increase in fertile life for the control group of 1.7 years. After the multivariate analysis, we found previous intake of tamoxifen to be a risk factor for the development of FFA (OR 14.89). The only protective factor identified was the previous use of an intrauterine device (IUD) (OR 0.22). CONCLUSIONS: An earlier menopause and tamoxifen intake might promote or maintain FFA, while the use of an IUD might protect from developing FFA. Our results support the previously proposed hypothesis of an underlying hormonal mechanism in the etiopathogenesis of FFA and point out low-estrogen environments as an ideal condition for FFA development.

RESUMO

Folliculitis decalvans (FD) is a primary neutrophilic scarring alopecia characterized by perifollicular papules, crusts, and pustules frequently located on the vertex. FD may affect young men and women. Since it may lead to hair loss, it can have a negative impact on patients' quality of life. Nevertheless, studies have focused on clinical, prognostic, and therapeutic aspects without considering the psychological impact of FD. In our study, we found that FD patients experienced a considerable impact on their quality of life. Interestingly, almost half of the patients considered that their alopecia was related to a poor medical care in their past. To our knowledge, this is the first description of the impact of FD on patients' quality of life, and it highlights the importance of psychological support for these patients.

RESUMO

In this article, we analyze branching angles of the basal dendrites of pyramidal neurons of layers III and V of the human temporal cortex. For this, we use a novel probability directional statistical distribution called truncated von Mises distribution that is able to describe more accurately the dendritic-branching angles than the previous proposals. Then, we perform comparative studies using this statistical method to determine similarities and/or differences between branches and branching angles that belong to different cortical layers and regions. Using this methodology, we found that common design principles exist and govern the patterns found in the different branches that compose the basal dendrites of human pyramidal cells of the temporal cortex. However, particular differences were found between supra and infragranular cells. Furthermore, we compared the branching angles of human layer III pyramidal neurons with data obtained in the previous studies in layer III of both the rat somatosensory cortex and of several cortical areas of the mouse. Finally, we study the branching angle differences between the humans that compose our data.
