Comparison of Blended Learning With Traditional Dermatology Learning for Medical Students: Prospective Evaluation Study.

BACKGROUND: Novel internet-based applications and associated technologies have influenced all aspects of society, ranging from commerce and business to entertainment and health care, and education is no exception. In this context, this study was designed to evaluate the impact of a dermatology e-learning program on the academic performance of medical students in dermatology. OBJECTIVE: The aim of this study is to develop a dermatology blended-learning course for undergraduate medical students, evaluate the knowledge gained by students exposed to this course, and compare the results to those of traditional teaching methods. METHODS: In this prospective study, we evaluated the performance of fourth-semester medical students at the Federal University of Bahia, Brazil. Students who had been in their second year of the medical course in 2019 were considered the control group, while students in their second year in 2020 were considered the blended or hybrid group. The first group attended traditional classes, using printed material (books and handouts), while the second group used our web-based course and e-book as a supplement in a hybrid web-plus-traditional fashion. Neither participants nor evaluators were blinded. The students in both groups were subjected to the same pre- and postcourse face-to-face, multiple-choice, paper-based evaluations, and we compared their performances. The content of the classes was the same for both groups. All didactic activities were developed by a team of certified dermatologists and professors from the university. RESULTS: A total of 129 students were selected and divided into 2 groups: the control group (n=57) and the hybrid group (n=72). The precourse tests did not indicate any difference between the control group (mean score 2.74, SD 1.25) and the hybrid group (mean score 3.2, SD 1.22 SD; P>.05). The hybrid group had better final-term grades (mean 8.18, SD 1.26) than the traditional group (mean 7.11, SD 1.04). This difference was statistically significant (P<.05). CONCLUSIONS: This study explores pedagogical possibilities in the field of dermatology teaching for medical school students. The results suggest that the performance of undergraduate students who attended the course with additional e-learning material was superior when compared to the performance of those who participated in the traditional course alone.

Invitro effect of pine bark extract on melanin synthesis, tyrosinase activity, production of endothelin-1, and PPAR in cultured melanocytes exposed to Ultraviolet, Infrared, and Visible light radiation.

BACKGROUND: French maritime pine bark (Pinus pinaster) extract (PBE), the registered trade name of which is Pycnogenol® , has been studied for its depigmenting action due to its antioxidant, anti-inflammatory, and anti-melanogenic activity. However, the mechanisms through which PBE are still not fully clear. OBJECTIVE: Evaluate the impact of PBE on four in vitro parameters closely associated with cutaneous pigmentation, including melanin synthesis, tyrosinase activity, endothelin-1 (ED1), and production of peroxisome proliferator-activated receptor α, δ, and γ (PPAR α, δ, and γ), by studying the modulation of action of ultraviolet radiation A (UVA)/ultraviolet radiation B (UVB), infrared-A (IR-A), visible light (VL), and association of UVA/UVB, IR-A, and VL (ASS). METHODS: Human melanocytes were incubated in a dry extract solution of PBE, exposed to UVA/UVB, IR-A, VL, and ASS for subsequent quantification of melanin, ED1, and PPAR α, δ, and γ. The effects of PBE on inhibition of tyrosinase activity were also performed by monophenolase activity assay. RESULTS: UVA/UVB, IR-A, VL, and ASS radiation caused significant increases in the synthesis of melanin, ED1, and PPAR α, δ, and γ when compared to baseline control. However, PBE significantly reduced the production of melanin, ED1, and PPAR α, δ, and γ, as well as reducing about 66.5% of the tyrosinase activity. CONCLUSIONS: PBE reduces in vitro melanin production by downregulating tyrosinase and reducing pigmentation-related mediators, such as ED1 and PPAR α, δ, and γ, therefore contributing to the inhibition of pathways associated with skin hyperpigmentation.

Clinical characteristics of COVID-19 patients and the main nursing diagnoses / Características clínicas dos pacientes COVID-19 e os principais diagnósticos de enfermagem

AIMS: to present a reflection on the clinic of patients infected by COVID-19 and to propose the main nursing diagnoses based on International Classification for Nursing Practice (ICNP©). METHOD: this is a reflection study, in which the selection criteria used were articles indexed in the MEDLINE, LILACS and BDENF databases published between December 2019 and April 2020, in English and Portuguese. RESULTS: 10 scientific articles were part of the study, which made it possible to know the symptomatologic profile of the disease, with emphasis on the classic triad of COVID-19, which is cough, shortness of breath and fever. It revealed that the basic human need most affected in this patient profile is oxygenation in view of hypoxemia being the main complication, for which the clinical outcome was negative, especially in elderly patients. CONCLUSION: there was a shortage and studies related to nursing in the face of this pandemic, but it was possible to conclude that ICNP© is one of the taxonomies that can be used to implement nursing diagnoses and intervention, the most frequent nursing diagnoses are related to the basic human and social need for oxygenation and vascular regulation.

Analysis of the availability of the resources necessary for urgent and emergency healthcare in São Paulo between 2009-2013.

INTRODUCTION:: The Regulatory Complex is the structure that operationalizes actions for making resources available to meet the needs of urgent and emergency care in the municipality of São Paulo. In the case of urgent care, needs are immediate and associated with high morbidity and mortality. OBJECTIVE:: To identify the most frequently requested resources, the resolution capacity and the mortality rate associated with the unavailability of a certain resource. METHOD:: Our study was based on data from medical bulletins issued by the Urgent and Emergency Regulation Center (CRUE) in the city of São Paulo from 2009 to 2013. RESULTS:: 91,823 requests were made over the five years of the study (2009 to 2013). Neurosurgery requests were the most frequent in all years (4,828, 5,159, 4,251, 5,008 and 4,394, respectively), followed by computed tomography (CT) scans, adult intensive care unit (ICU) beds, cardiac catheterization, and pediatric ICU beds. On average, requests for neurosurgery, adult ICU, pediatric ICU, CT scans, catheterization and vascular surgery were answered in 70%, 27%, 39%, 97%, 87% and 77% of cases. The total number of deaths relating to requests for neurosurgery, CT scans, adult ICU, pediatric ICU, catheterization and vascular surgeon assessment were 182, 9, 1,536, 1,536, 135, 49 and 24 cases, respectively. CONCLUSION:: There is a lack of resources to meet urgent and emergency needs in the city of São Paulo.

Oral health conditions in leprosy cases in hyperendemic area of the Brazilian Amazon.

Leprosy is a hyperendemic chronic condition in the Rondônia State . Despite the significant impact of oral health on the quality of life and clinical evolution of leprosy patients, systematic evaluation of oral health status has been neglected. To analyze the dental-clinical profile, self-perceived oral health and dental health service access of leprosy cases in the municipality of Cacoal in Rondônia State , North Brazil, from 2001 to 2012. A descriptive, cross-sectional study design was performed based on dental evaluation and standardized structured instruments. We investigated clinically assessed and self-perceived oral health status, as well as dental health service access. A total of 303 leprosy cases were included; 41.6% rated their oral health as good, and 42.6% reported being satisfied with their oral health. Self-reported loss of upper teeth was 45.5%. The clinical evaluation revealed that 54.5% had active caries. Most (97.7%) cases reported having been to the dentist at least once in their life and 23.1% used public health services. The poor standard of oral health in this population may increase the risk for leprosy reactions, consequently reducing quality of life. Low access to public health dental services and poor self-perceived oral health reinforce the need to achieve comprehensive health care in this population.

Extensive colorectal lymphomatous polyposis complicated by acute intestinal obstruction: a case report.

BACKGROUND: Multiple lymphomatous polyposis is a rare type of gastrointestinal lymphoma that extensively infiltrates the intestine. Multiple lymphomatous polyposis originates from the mantle zone of the lymphoma follicle and is considered to be a mantle cell lymphoma, which is a relatively aggressive type of B-cell non-Hodgkin's lymphoma. We report an unusual case of a patient with multiple lymphomatous polyposis with extensive colorectal involvement and acute intestinal obstruction, an atypical complication of this rare disease. On the basis of this case study, the pitfalls in gastrointestinal tract lymphomatous polyposis diagnosis and prognosis, as well as the treatment options, are discussed. CASE PRESENTATION: Our patient was a 76-year-old white woman with asthenia, cramps, and swelling in the lower left quadrant of the abdomen, as well as weight loss within the previous 5 months. A colonoscopy revealed polyps in the rectum, sigmoid colon, descending colon, and right and left colic flexures. A biopsy revealed lymphomatous infiltration of the intestinal wall. Because of the large size of the polypoid masses, which narrowed the colonic lumen in multiple locations, the patient developed acute intestinal obstruction and was referred for laparotomy. She underwent a total proctocolectomy with a permanent ileostomy and a left salpingo-oophorectomy. Microscopic examination showed the presence of a multicentric, low-grade, small lymphocytic lymphoma. Immunohistochemical analysis revealed positive immunostaining for CD79a, CD20, and CD45. These results were consistent with the diagnosis of mantle cell lymphoma. Two weeks after surgery and prior to discharge, but before the beginning of chemotherapy, the patient's general condition worsened as she experienced a severe and progressive respiratory tract infection, advanced respiratory insufficiency, and septic shock, and she ultimately died. CONCLUSIONS: Mantle cell lymphoma develops as a progressive and aggressive disease with widespread polyposis of the gastrointestinal tract. The intensive chemotherapeutic regimens usually result in the regression of macroscopic and microscopic lesions; however, remissions are short in duration, and the median length of patient survival is 3-4 years. Mantle cell lymphoma is a rare disease that should be part of the differential diagnosis of polypoid diseases of the large intestine.

Avaliação da qualidade de vida: comparação entre idosos não institucionalizados participantes de um centro de convivência e idosos institucionalizados em Ji-Paraná/RO / Evaluation of quality of life: a comparison between non- institutionalized elderly participatingin a community center and institutionalizd elderly in Ji-Paraná/RO

Os idosos no Brasil representam uma população significativa em números, com tendência a aumentar nas próximas décadas. Com isso, surge a preocupação com a qualidade de vida desta população. Assim, o presente trabalho objetivou avaliar a qualidade de vida de idosos não institucionalizados, participantes de um centro de convivência e de idosos institucionalizados, comparando os resultados entre os dois grupos. Para a coleta de dados foram utilizados dois instrumentos de avaliação da qualidade de vida da Organização Mundial da Saúde, o WHOQOL-OLD e o WHOQOL-bref. Estes foram aplicados a 100 idosos, composto por 37 homens e 63 mulheres de um centro de convivência e a 36 idosos, composto de 25 homens e 11 mulheres, residentes em uma instituição de longa permanência, sendo os dois grupos de Ji-Paraná, Rondônia. Utilizou-se o software SPSS for Windows versão 20.0 para análise dos dados e as variáveis do estudo receberam tratamento estatístico descritivo. Também, foram realizados testes de inferência estatística para verifi car possíveis associações entre as variáveis. Para as análises inferenciais foi utilizado o nível de significância α = 1%. Os resultados demonstraram relevância significativa na comparação entre os grupos. Os idosos institucionalizados apresentaram grau de satisfação inferior, comparados aos idosos não institucionalizados, nos quatro domínios (físico, psicológico, relações sociais e meio ambiente) do WHOQOL- -bref, e nos seis domínios (função sensorial, autonomia, atividades passadas, presentes e futuras, participação social, morte e morrer e intimidade) do WHOQOL-OLD. Por isso, é necessária a atenção urgente aos idosos institucionalizados, é preciso buscar formas de inseri-los no convívio social e sempre que possível, criar condições para que os mesmos possam manter vínculos com seus familiares.

The elderly are a significant part of the population of Brazil, and the number of old age people tends to increase in the coming decades. With this comes an increasing concern about the quality of life of this segment of the population. Thus, the present study aimed to evaluate the quality of life of two groups: one formed by non-institutionalized elderly participating in a community center; and the other formed by institutionalized elderly, and compare the results between them. To collect data, two instruments for assessing the quality of life of the World Health Organization were used: the WHOQOL-OLD and the WHOQOL-BREF. These assessment tools were applied to 100 elderly people, comprising 37 men and 63 women from a community center, and 36 elderly, comprising 25 men and 11 women, living in a long stay institution, both groups from the municipality of Ji-Paraná, Rondônia, Brazil. The SPSS software for Windows version 20.0 was used for data analysis and the variables in the study received a descriptive statistical treatment. Statistical inference tests were also performed to verify possible associations between variables. For inferential analysis, the level of significance α = 1% was used. The results showed relevant statistical significance in the comparison between groups. The institutionalized elderly showed lower levels of satisfaction when compared to the non-institutionalized elderly in the four domains of WHOQOL-BREF (physical health; psychological; social relationships; and environment), as well as in the six domains of WHOQOL-OLD (sensory abilities; autonomy; past, present and future activities; social participation; death and dying; and intimacy). Therefore, institutionalized elderly require urgent attention. It is a must to fi nd ways of inserting them into social life and, whenever possible, to create conditions for them to keep in touch and maintain ties with their families. (AU)

Os idosos institucionalizados apresentaram grau de satisfação inferior, comparados aos idosos não institucionalizados, nos quatro domínios (físico, psicológico, relações sociais e meio ambiente) do WHOQOL- -bref, e nos seis domínios (função sensorial, autonomia, atividades passadas, presentes e futuras, participação social, morte e morrer e intimidade) do WHOQOL-OLD. Por isso, é necessária a atenção urgente aos idosos institucionalizados, é preciso buscar formas de inseri-los no convívio social e sempre que possível, criar condições para que os mesmos possam manter vínculos com seus familiares.

The elderly are a significant part of the population of Brazil, and the number of old age people tends to increase in the coming decades. With this comes an increasing concern about the quality of life of this segment of the population. Thus, the present study aimed to evaluate the quality of life of two groups: one formed by non-institutionalized elderly participating in a community center; and the other formed by institutionalized elderly, and compare the results between them. To collect data, two instruments for assessing the quality of life of the World Health Organization were used: the WHOQOL-OLD and the WHOQOL-BREF. These assessment tools were applied to 100 elderly people, comprising 37 men and 63 women from a community center, and 36 elderly, comprising 25 men and 11 women, living in a long stay institution, both groups from the municipality of Ji-Paraná, Rondônia, Brazil. The SPSS software for Windows version 20.0 was used for data analysis and the variables in the study received a descriptive statistical treatment. Statistical inference tests were also performed to verify possible associations between variables. For inferential analysis, the level of significance α = 1% was used. The results showed relevant statistical significance in the comparison between groups. The institutionalized elderly showed lower levels of satisfaction when compared to the non-institutionalized elderly in the four domains of WHOQOL-BREF (physical health; psychological; social relationships; and environment), as well as in the six domains of WHOQOL-OLD (sensory abilities; autonomy; past, present and future activities; social participation; death and dying; and intimacy). Therefore, institutionalized elderly require urgent attention. It is a must to fi nd ways of inserting them into social life and, whenever possible, to create conditions for them to keep in touch and maintain ties with their families.

Toll-like receptors (TLR) 2 and 4 expression of keratinocytes from patients with localized and disseminated dermatophytosis.

There are few studies on the role of innate immune response in dermatophytosis. An investigation was conducted to define the involvement of Toll-Like Receptors (TLRs) 2 and 4 in localized (LD) and disseminated (DD) dermatophytosis due to T. rubrum. Fifteen newly diagnosed patients, eight patients with LD and seven with DD, defined by involvement of at least three body segments were used in this study. Controls comprised twenty skin samples from healthy individuals undergoing plastic surgery. TLR2 and TLR4 were quantified in skin lesions by immunohistochemistry. A reduced expression of TLR4 in the lower and upper epidermis of both LD and DD patients was found compared to controls; TLR2 expression was preserved in the upper and lower epidermis of all three groups. As TLR4 signaling induces the production of inflammatory cytokines and neutrophils recruitment, its reduced expression likely contributed to the lack of resolution of the infection and the consequent chronic nature of the dermatophytosis. As TLR2 expression acts to limit the inflammatory process and preserves the epidermal structure, its preserved expression may also contribute to the persistent infection and limited inflammation that are characteristic of dermatophytic infections.

A literatura sobre o papel da resposta imune inata em dermatofitose é escassa. Este estudo se propôs a investigar a participação dos receptores do tipo Toll 2 e 4 (TLRs) 2 e 4 em pacientes com dermatofitose localizada (LD) e disseminada (DD, definida como lesões em pelo menos três segmentos corpóreos distintos), causadas por Trichophyton rubrum. Foram analisados cortes histológicos de 15 pacientes recém-diagnosticados, oito com LD e sete com DD. O grupo controle foi composto por 20 amostras de pele de indivíduos saudáveis submetidos a cirurgia plástica. TLR-2 e TLR-4 foram quantificados em lesões cutâneas por imunohistoquímica. Encontramos uma expressão reduzida de TLR-4 na epiderme superior e inferior nos dois grupos, LD e DD, quando comparados com o grupo controle; a expressão de TLR-2 foi preservada na epiderme superior e inferior de todos os três grupos. Como a sinalização por TLR-4 induz produção de citocinas inflamatórias e recrutamento de neutrófilos, a menor expressão desta molécula provavelmente contribui para a não resolução da infecção e conseqüente natureza persistente da dermatofitose. Como a sinalização via TLR-2 tem sido descrita como fator de regulação do processo inflamatório e de preservação da estrutura epidérmica, a sua expressão inalterada nas lesões dos pacientes com DD e DL pode contribuir também para a persistência da infecção e do reduzido processo inflamatório que são característicos das infecções por dermatófitos.
