Aminolevulinic Acid-Photodynamic Therapy for Erosive Pustular Dermatosis of the Scalp: Comparison of Two Treatment Protocols and Participant Satisfaction.

Treatment of erosive pustular dermatosis of the scalp (EPDS) is challenging. Topical and systemic medications have achieved limited success, and destructive modalities have been associated with EPDS recurrence because of the tendency of the condition to recur after any treatment that induces trauma to the skin. Our group has have recently reported two series of EPDS treated with aminolevulinic acid-photodynamic therapy (ALA-PDT). Here, we aimed at comparing the protocols utilized in those series regarding efficacy, cost, and patient satisfaction. The first protocol included one visit for curettage of the hyperkeratosis and a second one for ALA-PDT. The revised (second) protocol included all procedures (curettage and ALA-PDT) in one visit. A novel silicone gel was applied immediately after completion of PDT, and patients were instructed to apply it twice daily over the treated areas until their follow-up visit. Both protocols were efficacious and provided similar length of remission. The second protocol was less costly. Patients treated using the second protocol were more satisfied due to the ease of treatment completion in one visit and better postoperative healing. (SKINmed. 2022;20:107-112).

Skin disease related to metabolic syndrome in women.

Sex hormones are involved in pathways of metabolic syndrome (MetS), an observation supported by animal studies. The relationships of sex hormones with components of MetS, such as insulin resistance and dyslipidemia, have been studied in pre- and postmenopausal women. High testosterone, low sex hormone-binding globulin, and low estrogen levels increase the risks of MetS and type 2 diabetes in women. Cutaneous diseases that are sex hormone mediated, such as polycystic ovary syndrome, acanthosis nigricans, acne vulgaris, and pattern alopecia, have been associated with insulin resistance and increased risk for MetS. Furthermore, inflammatory skin conditions, such as hidradenitis suppurativa and psoriasis, increase the risk for MetS. Patients with such skin conditions should be followed for metabolic complications, and early lifestyle interventions toward these populations may be warranted.

Travelers' tropical skin diseases: Challenges and interventions.

Tropical regions receive a significant part of the traveling population. It is very important that health professionals are familiar with the main tropical skin diseases and able to advice patients appropriately. This article reviews the main tropical diseases of travelers, with an emphasis on diagnosis, management, and prevention. Among others, cutaneous larva migrans, myiasis, tungiasis, Chagas disease, Dengue fever, African trypanosomiasis, filariasis, and leishmaniasis are discussed. Increasing awareness among travelers and health care professionals can help reduce morbidity and mortality. Continued research on new drugs and vaccines is needed to reduce the risks of tropical diseases.

Acne Scarring Management: Systematic Review and Evaluation of the Evidence.

BACKGROUND: Modalities for atrophic acne scarring can be classified depending upon the needs they satisfy; that is, resurfacing, lifting/volumization, tightening, or surgical removal/movement of tissue that is required for correction. A plethora of treatment options have resulted from the need to treat various acne scar types, variability of responses noted in various skin types, and increasing popularity of minimally invasive modalities. Still, there is a lack of consensus guidelines on treatment or combination therapies for various clinical scenarios. OBJECTIVE: This systematic review includes a critical evaluation of the evidence relevant to these modalities and various multimodality therapies. METHODS: We performed a systematic literature search in Medline and EMBASE databases for studies on acne scar management. Also, we checked the reference lists of included studies and review articles for further studies. A total of 89 studies were included in our quality of evidence evaluation. RESULTS: The efficacy of lasers and radiofrequency in atrophic acne scarring is confirmed by many comparative and observational studies. Other modalities can be used as an adjunct, the choice of which depends on the type, severity, and number of atrophic scars. Minimally invasive procedures, such as fractional radiofrequency and needling, provide good outcomes with negligible risks in patients with dark or sensitive skin types. CONCLUSIONS: There is a lack of high-quality data. Fractional lasers and radiofrequency offer significant improvement in most types of atrophic acne scars with minimal risks and can be combined with all other treatment options. Combination therapies typically provide superior outcomes than solo treatments.

Body dysmorphic disorder in the cosmetic practice.

Body dysmorphic disorder (BDD) is a preoccupation with a slight or imagined flaw in appearance that causes significant distress and impairment in daily functioning. The disease is more prevalent among patients who seek aesthetic procedures as compared with population standards or individuals that are not interested in aesthetic surgery. Several studies have indicated that BDD symptoms typically worsen after an aesthetic procedure because the preoccupation shifts to a different body area. This review discusses the demographic and clinical features, psychiatric comorbidity, assessment, differential diagnosis, and management of BDD. Components of the assessment include the interview, patient observation in the office, and questionnaires. The article includes a detailed discussion on questionnaires, especially those that are most useful in the dermatology or cosmetic practice. Ethical considerations in the management of BDD are discussed. BDD should not be missed by health providers because of the associated high morbidity that includes an increased suicidality. The cosmetic provider's approach should motivate BDD patients to participate in treatment, a combination of psychotherapy and pharmacotherapy.

SITRUS: Semantic Infrastructure for Wireless Sensor Networks.

Wireless sensor networks (WSNs) are made up of nodes with limited resources, such as processing, bandwidth, memory and, most importantly, energy. For this reason, it is essential that WSNs always work to reduce the power consumption as much as possible in order to maximize its lifetime. In this context, this paper presents SITRUS (semantic infrastructure for wireless sensor networks), which aims to reduce the power consumption of WSN nodes using ontologies. SITRUS consists of two major parts: a message-oriented middleware responsible for both an oriented message communication service and a reconfiguration service; and a semantic information processing module whose purpose is to generate a semantic database that provides the basis to decide whether a WSN node needs to be reconfigurated or not. In order to evaluate the proposed solution, we carried out an experimental evaluation to assess the power consumption and memory usage of WSN applications built atop SITRUS.

Notalgia paraesthetica: a descriptive two-cohort study of 65 patients from Brazil and Germany.

Notalgia paraesthetica is a neuropathic pruritus on the back. The aim of this retrospective study was to examine patient characteristics in a consecutive cohort from Brazil and Germany. A total of 65 patients (49 women, 16 men; age range 25-80 years, mean 56.2 ± 12.7 years; median 57.0 years) were investigated in order to determine the spinal or peripheral origin of notalgia paraesthetica. Protein gene product 9.5-positive intraepidermal nerve fibers were significantly reduced in the pruritic compared with the non-lesional area (p < 0.05). In 32.3% of patients, radiological examinations showed a stenosis and in 47.7% a degeneration. A correlation between the radiological findings and the exact dermatomal localization of notalgia paraesthetica was found in 15.7% of the involved areas. The significant reduction in intraepidermal nerve fiber density suggests that damage to the peripheral nerves is a more important aetiological factor than spinal changes in notalgia paraesthetica.

[Case for diagnosis. Langerhans cell histiocytosis]. / Caso para diagnóstico. Histiocitose de celulas de Langerhans.

Langerhans cell histiocytosis is a rare disease of unknown cause, characterized by the proliferation of histiocytic cells (Langerhans cells). Its diagnosis is especially difficult due to its wide clinical spectrum, ranging from a single lesion to a multisystemic disorder. Diagnosis may be confirmed by means of an immunohistochemical study. Treatment depends upon the severity of the disease, and systemic chemotherapy may be needed.

Estrias: fator de risco para distopia urogenital? / Striae: a risk factor for urogenital dystopia?

Fundamento: Estrias são placas lineares atróficas associadas a estiramento da pele.A distopia urogenital é o deslocamento de um órgão pélvico de seu sítio habitual devido a alterações de suas estruturas de sustentação. Há estudos histopatológicos que revelam igual distribuição irregular de fibras colágenas no tecido das estrias e do assoalho das pacientes com relaxamento pélvico. Objetivo: Avaliar a prevalência de estrias em pacientes com e sem relaxamento pélvico, verificando se há a associação de risco entre elas. Método: Foram estudadas pacientes, portadoras comprovadas de distopia genital e mulheres sadias.Todas foram submetidas a exame físico e aplicação de questionário com 80 perguntas elaboradas especificamente para essa pesquisa. Resultado: Não foi verificada diferença estatística significativa na prevalência de estrias em pacientes com distopia urogenital (n=35) comparada com os controles (n=94), sugerindo ausência dessa associação. Conclusão: A associação entre as duas condições, estrias e distopia genital, antes sugerida por outros autores, não foi demonstrada neste trabalho. Como implicação prática, provou- se que as estrias não constituem fator de risco para relaxamento pélvico, havendo necessidade de investigar outros marcadores clínicos capazes de possibilitar medidas preventivas e a redução dos gastos com o tratamento cirúrgico dos prolapsos.

Background: Striae are linear atrophic plaques associated with overstretching the skin (commonly called stretch marks). Urogenital dystopia is the displacement of a pelvic organ from its original site due to alterations in or relaxation of the pelvic supporting structures. Histopathologic studies have revealed similarities in the irregularity of the distribution patterns of collagen fibers located in the striae's tissue and in the pelvic floor of patients suffering from pelvic relaxation or prolapse. Objective: To evaluate the prevalence of striae in patients with and without pelvic relaxation syndrome, in order to assess the association between the two conditions. Methods: Female patients with genital dystopia and healthy controls were administered an 80- question instrument specifically designed for this study and received a physical examination to determine whether there is a link between striae and genital dystopia. Results: No statistically significant difference was observed in the prevalence of striae in patients with genital dystopia (n=35) compared with controls (n=94), suggesting there is no association between the two conditions. Conclusion: The association between striae and genital dystopia, previously suggested by other authors, was not verified in this study. Since striae are not a risk factor for pelvic relaxation, it is necessary to investigate other clinical markers that will enable preventive measures and the reduction of costs associated with the surgical treatment of prolapse.

Autoimmune bullous dermatoses.

Autoimmune bullous dermatoses are diseases in which blisters and vesicles are the primary and fundamental types of skin lesion. Their classification is based on the location of the blister: intraepidermal and subepidermal. Patients produce autoantibodies against self-specific structures of the skin detectable by immunofluorescence techniques, immunoblotting and ELISA. Recent advances in molecular and cellular biology have brought to knowledge these self-antigens, against which patients are sensitized, and which are found in epidermis or in the dermo-epidermal junction. These are low incidence, but high morbidity diseases that may be fatal. The aim of this article is to review and describe the progress of four autoimmune vesiculobullous disorders: endemic pemphigus foliaceous (wild fire), pemphigus vulgaris, bullous pemphigoid and dermatitis herpetiformis.

Dermatoses bolhosas auto-imunes / Autoimmune bullous dermatoses

Dermatoses bolhosas autoimunes são doenças cuja manifestação cutânea primária e fundamental consiste em vesículas e bolhas. Classificam-se conforme a localização da bolha, em intraepidérmica e subepidérmica. Os pacientes produzem autoanticorpos contra estruturas específicas da pele detectáveis por técnicas de imunofluorescência, immunobloting e Elisa. Os recentes avanços da biologia molecular e celular têm permitido conhecer esses autoantígenos, contra os quais os pacientes se sensibilizam e que estão localizados na epiderme ou na junção dermoepidérmica. São doenças de baixa incidência, porém de elevada morbidade e por vezes letais. O objetivo deste trabalho é revisar e descrever os progressos nos conhecimentos de quatro doenças vésico-bolhosas autoimunes: pênfigo foliáceo endêmico (fogo selvagem), pênfigo vulgar, penfigóide bolhoso e dermatite herpetiforme.
