Abstract Objective: To evaluate physical and mental health indicators in adolescents with preexisting chronic immunocompromised conditions during coronavirus disease 2019 (COVID-19) quarantine. Methods: A cross-sectional study included 355 adolescents with chronic conditions and 111 healthy adolescents. An online self-rated survey was used to investigate socio-demographic features, healthcare routine, and the quarantine impact on physical and mental health. The validated self-reported version of the Strengths and Difficulties Questionnaire (SDQ) was also applied. Results: The median of age [14 (10–18) vs. 15 (10–18) years, p = 0.733] and frequencies of female (61% vs. 60%, p = 0.970) were similar between adolescents with preexisting chronic conditions and healthy adolescents during quarantine of COVID-19 pandemic. The frequencies of abnormal total difficulties score of SDQ were similar in patients and controls (30% vs. 31%, p = 0.775). Logistic regression analysis showed that being female (OR = 1.965; 95% CI = 1.091–3.541, p = 0.024), fear of underlying disease activity/complication (OR = 1.009; 95%CI = 1.001–1.018, p = 0.030) were associated with severe psychosocial dysfunction in adolescents with chronic conditions, whereas school homework (OR = 0.449; 95% CI = 0.206–0.981, p = 0.045) and physical activity (OR = 0.990; 95% CI = 0.981–0.999, p = 0.030) were protective factors. Further analysis of patients with chronic immunocompromised conditions and previous diagnosis of mental disorders (9%) compared with patients without diagnosis showed higher median of total difficulties score (p = 0.001), emotional (p = 0.005), conduct (p = 0.007), peer problems (p = 0.001) and hyperactivity (p = 0.034) in the former group. Conclusion: Adolescents with preexisting chronic immunocompromised conditions during COVID-19 quarantine were not at higher risk of adverse health indicators. Being female, fear of underlying disease activity/complication, and household members working outside of the home were relevant issues for adolescents with preexisting chronic conditions. This study reinforces the need to establish mental health strategies for teens with chronic conditions, particularly during the pandemic.

Introdução: A alopecia frontal fibrosante (AFF) é uma cicatriz linfocítica, com queda de cabelo pela linha de implantação frontal do couro cabeludo e outras áreas do corpo. Drogas tópicas e sistêmicas, como casos o MTX, não controlam a atividade da doença na maioria dos casos, a necessidade de novas terapias. Objetivo: Avaliar a diligência da microinfusão de metotrexato em AFF. Métodos: Ensaio clínico prospectivo, controlador, realizado com 17 voluntários com 1 diagnóstico clínico e histológico de AFF. As aplicações de MTX por MMP® (método de microinfusão de pele) foram feitas a cada 30 dias, num total de 3 aplicações, na direita da área de alopecia; a outra metade serviu como controle.medidas frontais glalares e parciais, dermatoscópicas, índice de avaliação externa dos olhos, a percepção do plano dos sinais do paciente (LPPAI). Hemograma total e testes de função hepática também foram médios. Resultados: Houve uma redução significativa nas medidas fronto-glabela e frontal temporo-parietal no local tratado, enquanto no local nãou a AAF aumentou. A paciente refere melhora do prurido e descamação, mas não da queda de cabelo e eritema local. A das fotos dermatoscópicas e a análise do LPPAI não são relevantes. Cerca de 9 participantes e todos nós não resultaram em 5% dos resultados com nenhum resultado de nenhum dos exames.Conclusão: A aplicação de MTX por MMP® melhorou os sintomas associados à AFF e as medidas fronto-glabela e fronto-parietal.

As aplicações de MTX por MMP® (método de microinfusão de drogas na pele) foram feitas a cada 30 dias, totalizando 3 aplicações, na metade direita da área da alopecia; a outra metade serviu como controle. Foram avaliadas as medidas frontoglabela e frontal temporoparietal. Fotos de dermatoscopia foram analisadas por avaliadores cegos e externos com percepção de sinais e sintomas do paciente e o Índice de Atividade do Líquen Planopilar (LPPAI). Hemograma total e testes de função hepática também foram medidos. Resultados: Houve redução significativa nas medidas frontoglabela e frontal temporoparietal no local tratado, enquanto no não tratado a AAF aumentou. Houve melhora do prurido e descamação, mas não da queda de cabelo e eritema local. A análise das fotos dermatoscópicas e o cálculo do LPPAI não mostraram alterações relevantes. Cerca de 95% dos participantes ficaram satisfeitos ou muito satisfeitos com os resultados e nenhum deles teve alteração nos resultados dos exames laboratoriais. Conclusão: A aplicação de MTX por MMP® melhorou os sintomas associados à AFF e as medidas frontoglabela e frontoparietal. Esta técnica mostrou-se segura e bem tolerada.

OBJECTIVE: To assess the possible factors that influence sleep quality in adolescents with and without chronic immunosuppressive conditions quarantined during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: This cross-sectional study included 305 adolescents with chronic immunocompromised conditions and 82 healthy adolescents. Online surveys were completed, which included questions on socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and the following validated questionnaires: the Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0), and Pediatric Outcome Data Collection Instrument (PODCI). RESULTS: The median current age [14 (10-18) vs. 15 (10-18) years, p=0.847] and frequency of female sex (62% vs. 58%, p=0.571) were similar in adolescents with chronic conditions compared with healthy adolescents. The frequency of poor sleep quality was similar in both groups (38% vs. 48%, p=0.118). Logistic regression analysis, including both healthy adolescents and adolescents with chronic conditions (n=387), demonstrated that self-reported increase in screen time (odds ratio [OR] 3.0; 95% confidence interval [CI] 1.3-6.8; p=0.008) and intrafamilial violence report (OR 2.1; 95% CI 1.2-3.5; p=0.008) were independently associated with poor sleep quality in these adolescents. However, the PODCI global function score was associated with a lower OR for poor sleep quality (OR 0.97; 95% CI 0.94-0.99; p=0.001). Further logistic regression, including only adolescents with chronic conditions (n=305), demonstrated that self-reported increase in screen time (OR 3.1; 95% CI 1.4-6.8; p=0.006) and intrafamilial violence report (OR 2.0; 95% CI 1.2-3.4; p=0.011) remained independently associated with poor quality of sleep, whereas a lower PODCI global function score was associated with a lower OR for sleep quality (OR 0.96; 95% CI 0.94-0.98; p<0.001). CONCLUSION: Self-reported increases in screen time and intrafamilial violence report impacted sleep quality in both healthy adolescents and those with chronic conditions. Decreased health-related quality of life was observed in adolescents with poor sleep quality.

Diabetes Mellitus (DM) is a metabolic syndrome characterized by hyperglycemia. Chronic complications affect a number of organs, including the lungs. Cissampelos sympodialis Eichl (Menispermaceae) is a plant used to treat respiratory diseases. The aim of this study was to evaluate the effect of Cissampelos sympodialis extract (CSE) in lungs of diabetic rats. We used 30 Wistar rats divided into three groups: control group (CG), diabetic group (DG) and diabetic Cissampelos sympodialis treatment group (DTG). Diabetes was induced by streptozotocin (40 mg/kg i.v.). The CSE (400 mg/kg, po) was administered daily, during four weeks, beginning one week after the onset of DM. The treatment with CSE was not able to reduce blood glucose levels after streptozotocin injection. However, it was able to decrease cholesterol and triglycerides and prevent damage on pancreatic islets morphology. Additionally, morphological alterations such as alveolar septa loss, inflammatory infiltrate and fibrosis were seen in lung tissue of rats with DM, and treatment with CSE apparently reversed these histopathological findings. Thus, CSE treatment reduced the lipid profile and restored the lung architecture of diabetic animals by a mechanism independent of glycemia and which might be associated with the reduction of the damage on the pancreatic islets.

Abstract Annona leptopetala (R.E.Fr.) H. Rainer, Annonaceae, is used in folk medicine like antitumor and anti-inflammatory. The aim of this study was to determine chemical composition, toxicity and antitumor activity of A. leptopetala leaves volatile oil. Fresh leaves were hydrodistilled and then the volatile oil chemical composition was assessed by gas chromatography and mass spectrometry. Toxicity was assessed using haemolysis, micronucleus and acute toxicity protocols. Antitumor effects were determined in vitro and in vivo, using sulforhodamine B assay and sarcoma 180 murine tumor model, respectively. Spathulenol was the major component identified (12.56%). The volatile oil showed in vitro antitumor activity mainly in leukemia cell line (K-562), with Total growth inhibit (TGI) (concentration producing TGI) of 0.64 µg/ml. In other hand, the volatile oil <250 µg/ml did not inhibit HaCat non-tumor cell line growth. The concentration that produced 50% haemolysis was 372.8 µg/ml. The 50% lethal dose in mice was approximately 447.2 mg/kg intraperitoneally. Sarcoma 180 tumor growth inhibition rates were 59.29% and 58.77% at 100 and 150 mg/kg intraperitoneally, respectively. The volatile oil presented moderate gastrointestinal toxicity and no genotoxicity was observed at 350 mg/kg. Thus, the volatile oil shows antitumor activity with moderate toxicity.

Abstract: Angiosarcoma is a rare and aggressive tumor with high rates of metastasis and relapse. It shows a particular predilection for the skin and superficial soft tissues. We report three distinct and typical cases of angiosarcoma that were diagnosed in a single dermatology clinic over the course of less than a year: i) Angiosarcoma in lower limb affected by chronic lymphedema, featuring Stewart-Treves syndrome; ii) a case of the most common type of angiosarcoma loated in the scalp and face of elderly man and; iii) a skin Angiosarcoma in previously irradiated breast. All lesions presented characteristic histopathological findings: irregular vascular proliferation that dissects the collagen bundles with atypical endothelial nuclei projection toward the lumen.

ABSTRACT The essential oil from Croton polyandrus Spreng., Euphorbiaceae, leaves was tested for the toxicity and antitumor activity. The concentration producing 50% hemolysis was 141 µg/ml on mice erythrocytes. In the acute toxicological study, the estimated LD50 was 447.18 mg/kg. The essential oil did not induce increase in number of micronucleated erythrocytes, suggesting low genotoxicity. Essential oil (100 or 150 mg/kg) showed significant antitumor activity in Ehrlich ascitic carcinoma model. We observed that essential oil induces cell-cycle arrest at the G0/G1 phase, and increases the sub-G1 peak, which represents a marker of cell death by apoptosis. Survival also increased for the treated animals. The toxicological analyses revealed reduction in body weight, increased aspartate aminotransferase and alanine aminotransferase activity, hematological changes, and a thymus index reduction. These data suggest gastrointestinal and liver toxicity, anemia, leukopenia/lymphocytopenia, and immunosuppressive effects. Histopathological analysis revealed the weak hepatotoxicity of essential oil. In summary, essential oil of C. polyandrus displays in vivo antitumor activity and moderate toxicity.

Abstract Bacillary angiomatosis is an infection determined by Bartonella henselae and B. quintana, rare and prevalent in patients with acquired immunodeficiency syndrome. We describe a case of a patient with AIDS and TCD4+ cells equal to 9/mm3, showing reddish-violet papular and nodular lesions, disseminated over the skin, most on the back of the right hand and third finger, with osteolysis of the distal phalanx observed by radiography. The findings of vascular proliferation with presence of bacilli, on the histopathological examination of the skin and bone lesions, led to the diagnosis of bacillary angiomatosis. Corroborating the literature, in the present case the infection affected a young man (29 years old) with advanced immunosuppression and clinical and histological lesions compatible with the diagnosis.

Abstract Histiocytoid Sweet's Syndrome is a rare inflammatory disease described in 2005 as a variant of the classical Sweet's Syndrome (SS). Histopathologically, the dermal inflammatory infiltrate is composed mainly of mononuclear cells that have a histiocytic appearance and represent immature myeloid cells. We describe a case of Histiocytoid Sweet's Syndrome in an 18-year-old man. Although this patient had clinical manifestations compatible with SS, the cutaneous lesions consisted of erythematous annular plaques, which are not typical for this entity and have not been described in histiocytic form so far. The histiocytic subtype was confirmed by histopathological analysis that showed positivity for myeloperoxidase in multiple cells with histiocytic appearance.

O medicamento fitoterápico brasileiro - BPF é composto de corantes das plantas Eucalyptus globulus Labill, Peltodon radicans Pohl e Schinus terebinthifolius Raddi em alcool a 13,3° GL. Este medicamento é popularmente usado no estado da Paraíba, Brasil desde 1889 como anti-séptico e antiinflamatório. O objetivo deste estudo foi avaliar a propriedade antiinflamatória deste medicamento fitoterápico. Para tal, foram utilizadas as técnicas de edema de orelha em camundongos induzido por 12-O-tetradecanoilforbol 13-acetato (TPA) ou capsaicina e o edema de pata de rato induzido por carragenina. O BPF na dose de 26 mL/kg inibiu tanto edema de orelha induzido por TPA como por capsaicina a 49% (p < 0.05) e 24% (p < 0.01) respectivamente. Estudos preliminares utilizando a técnica de edema de pata induzido por carragenina demonstraram que a administração oral também inibiu o edema de pata em aproximadamente 29%. Os resultados demonstraram que o medicamento fitoterápico brasileiro (BPF) apresentou propriedades antiinflamatórias e a melhor dose foi aquela que é usada pela população.

The Brazilian polyherbal formulation (BPF) is composed by dyes of Eucalyptus globulus Labill, Peltodon radicans Pohl and Schinus terebinthifolius Raddi in alcohol at 13.3° GL. The formulation is popularly used in Paraíba state, Brazil since 1889 and it is used as an antiseptic and anti-inflammatory medicine. The aim of this study was to evaluate the anti-inflammatory property of the polyherbal formulation. For this purpose it was used the12-O-tetradecanoylphorbol 13-acetate (TPA) and capsaicin-induced mouse ear edema and the carrageenan-induced rat paw edema. The BPF at dose of 26 mL/Kg inhibited both 12-O-tetradecanoylphorbol 13-acetate (TPA) and capsaicin-induced ear edema by 49% (p < 0.05) and 24% (p < 0.01) respectively. Preliminary results on carrageenan-induced rat paw edema demonstrated that oral administration also inhibited the paw edema by approximately 29%. The results demonstrate that the Brazilian polyherbal formulation has anti-inflammatory activity and the better dose was the one used by the population.

A Doença de Alzheimer (DA) é uma patologia neurodegenerativa, progressiva, que afeta principalmente a população idosa, responsável por 50-60% dos casos de demência em pessoas com mais de 65 anos de idade. Os principais sintomas associado a DA envolve deficiência orgânica cognitiva, principalmente perda de memória. Outras características associadas com os estágios avançados de DA inclui déficit na linguagem, depressão, problemas de comportamento, inclusive agitação, alterações de humor e psicose.Um dos mais promissores caminhos para tratar esta doença é aumentar o nível de acetilcolina no cérebro usando inibidores da acetilcolinesterase (AChE). Este trabalho teve como objetivo revisar a literatura das plantas e substâncias encontradas nas plantas, inibidores da enzima acetilcolinesterase. Foram levantadas 309 plantas e 260 substâncias isoladas de plantas que foram classificados em grupos químicos adequados, os modelo testados, e suas atividades. Foram consultados 175 referências.

Alzheimer's disease (AD) is a progressive, neurodegenerative pathology that primarily affects the elderly population, and is estimated to account for 50-60% of dementia cases in persons over 65 years of age. The main symptoms associated with AD involve cognitive dysfunction, primarily memory loss. Other features associated with the later stages of AD include language deficits, depression, behavioural problems including agitation, mood disturbances and psychosis. One of the most promising approaches for treating this disease is to enhance the acetylcholine level in the brain using acetylcholinesterase (AChE) inhibitors. The present work reviews the literature on plants and plant-derived compounds inhibitors of enzyme acetylcholinesterase. The review refers to 309 plant extracts and 260 compounds isolated from plants, which are classified in appropriate chemical groups and model tested, and cites their activity. For this purpose 175 references were consulted.
