ABSTRACT

Objective. )e aim of the present study was to report the physiological stimulation of the synthesis of preelastic fibers in the dermis of a patient with fibrosis. Design. A clinical study was conducted involving the analysis of histological changes in preelastic fibers following treatment for stage II primary lymphedema for the clinical reversal of lymphedema and fibrosis. Setting. University Hospital of the São Jose do Rio Preto of School of Medicine in 2020. Participant was a 67-year-old male patient with late-onset primary lymphedema diagnosed 12 years earlier. Intervention is the lymphatic stimulation using the Godoy method adapted to the treatment of fibrosis. Main outcomes and measures are biopsies before and after treatment. Ten randomly selected histological fields were evaluated using the multipoint morphometric method. )e values with this method are relative and expressed as percentages. Statistical analysis was performed with the t-test, considering a 95% significance level. Results. A visible, significant difference in the percentage of preelastic fibers was found between the preintervention and postintervention slides, which were confirmed by the microscopic evaluation and quantification (4.95 ± 0.64% and 14.70 ± 1.06%, respectively). Conclusion. )e physiological stimulation of the lymphatic system using a specific method resulted in the clinical reduction of fibrosis, the return of the elasticity of the skin, and the stimulation of the synthesis of preelastic fibers.

ABSTRACT

PURPOSE: To determine the efficacy of tranilast as an adjunctive therapy in conjunctival autograft. METHODS: Twenty-nine patients were randomly allocated to the Tranilast Group (n=15) or the Control Group (n=14). The Tranilast Group received a subconjunctival injection of 0.5% tranilast 30 days prior to surgery. Conjunctival autograft was performed in both groups using fibrin sealant and 0.02% subconjunctival mitomycin C at the end of the surgery. After the resection of the pterygium, immunohistochemistry was performed with 100 cells to identify epithelial cells positive for transforming growth factor-ß (TGF-ß). Subjective symptoms were evaluated using a 5-point scale, and the recurrence rate was assessed. RESULTS: Both groups showed improvements in their symptoms and similar clinical results. Compared with the Control Group, the Tranilast Group failed to show a decreased recurrence rate (p=0.59). However, the number of epithelial cells expressing TGF-ß was lower in the Tranilast Group (5 cells; 95% CI: 2.56-13.15; Control Group, 16 cells, 95% CI: 11.53-24.76; p=0.01). Minimal but reversible complications, including glaucoma secondary to corticosteroids and granuloma, occurred during the study. CONCLUSION: Tranilast was effective in decreasing the number of pterygium epithelial cells expressing TGF-ß.

Objetivo: Determinar a eficácia do tranilast, como terapia auxiliar no transplante autólogo de conjuntiva. Métodos: Vinte e nove pacientes foram randomizados em dois grupos: Grupo Tratado (15) e Grupo Controle (14). Trinta dias antes da cirurgia, o Grupo Tratado recebeu uma injeção subconjuntival de tranilast a 0,5%. O transplante autólogo de conjuntiva foi realizado em ambos os grupos, usando-se a cola de fibrina e a mitomicina 0,02% subconjuntival, ao final da cirurgia. Cada paciente foi examinado por 12 meses de acompanhamento. A imuno-histoquímica foi realizada, mediante um total de 100 células, a fim de que se contassem as células epiteliais positivas, para o fator de crescimento transformador beta (TGF-β), após a cirurgia do pterígio. Os sintomas subjetivos foram avaliados usando-se uma escala de cinco pontos, e a taxa de recorrência foi avaliada. Resultados: Os 2 grupos apresentaram melhora dos sintomas e com resultados clínicos similares. Quando comparado com o Grupo Controle, o Grupo Tratado falhou em mostrar uma diminuição da taxa de recorrência (p=0,59). Entretanto o número de células epiteliais expressando o TGF-β foi menor no Grupo Tratado (5 células; 95% CI=2,56-13,15; Grupo Controle, 16 células; 95% CI: 11,53-24,76, p=0,01). Complicações mínimas, mas reversíveis, ocorreram durante o estudo, incluindo glaucoma secundário ao uso de corticoide e granuloma. Conclusão: O tranilast foi efetivo em diminuir o número células epiteliais do pterígio expressando o TGF-β. .

ABSTRACT

Introdução: A Mucormicose é uma infecção oportunista rara causada por fungos da ordem dos Mucorales, sendo o Rhizopus o gênero mais comum (70% dos casos). Esta é uma infecção fúngica invasiva aguda que pode apresentar-se na forma disseminada, cutânea, pulmonar, gastrointestinal e rino-órbito-cerebral (forma mais comum). Nesta última, as queixas mais comuns são de rinorréia unilateral, febre e cefaléia. Quando há envolvimento orbitário as queixas podem ser de quemose, diplopia e diminuição da acuidade visual. A infecção pode disseminar-se para o Sistema Nervoso Central através do ápice orbitário, da placa cribiforme ou causar trombose em artérias que irrigam o Sistema Nervoso Central. A Mucormicose é uma emergência médica e o tratamento consiste na cirurgia para debridamento agressivo e no uso de antifúngicos sistêmicos. Mesmo com a terapêutica adequada à taxa de mortalidade chega a até 40% dos casos. Uma possível complicação intracraniana da Mucormicose é a Trombose de Seio Cavernoso que é uma infecção rara e com alta taxa de mortalidade. Na Trombose de Seio Cavernoso as queixas iniciais são de cefaléia, dor retro-orbital, edema periorbitário, proptose, diplopia e diminuição da acuidade visual. Relato do Caso: Nós relatamos o caso de uma paciente com 43 anos de idade com antecedentes de diabetes mellitus e uso drogas imunossupressoras para transplante renal, que desenvolveu quadro de Rinossinusite Bacteriana Aguda e Rinossinusite Fúngica Invasiva Aguda associada à Trombose de Seio Cavernoso.


Introduction: Mucormycosis is a rare opportunistic infection caused by Mucorales fungi, and the Rhizopus is the most common one (70% of the cases). It is an acute invasive fungal disease whose form is disseminated, cutaneous, pulmonary, gastrointestinal and rhino-orbitocerebral. The latter is the most common form and its symptoms comprise of unilateral sinusitis, fever and headache. Once established in the orbit the symptoms can be chemosis, diplopia and reduced vision. The infection can spread to the brain via the orbital apex, orbital arteries or via the cribriform plate. Mucormycosis is a medical emergency and the treatment consists of a surgery to an aggressive debridement and in the use of antifungal therapy. Despite the appropriate management, the mortality rate can reach 40% of the cases. One possible intracranial complication of Mucormycosis is the Cavernous Sinus Thrombosis which is a rare and fatal infective disease. The initial symptoms of Cavernous Sinus Thrombosis are headache, retro-orbital pain, periorbital edema, proptosis, diplopia and reduced vision. Case Report: We describe the case of 43-year-old woman with medical history of diabetes mellitus and use of immunosuppressant drugs after kidney transplantation. The patient developed Acute Bacterial Sinusitis and Rhino-orbitocerebral Mucormycosis associated with Cavernous Sinus Thrombosis.

ABSTRACT

UNLABELLED: Contemporary cohort cross-sectional study. INTRODUCTION: Despite its importance for an accurate diagnosis, histology differences among nasal polyps and its clinical implications are rarely reported in the literature. The existing papers classify polyp samples without concern for prior treatments, which could influence the results attained. AIMS: carry out a morphological study, through light microscopy, of nasal polyps' structural alterations in the absence of any type of prior treatment and histologically classify it in relation to studies published in the literature. MATERIALS AND METHODS: We studied 89 patients with nasosinusal polyps without prior treatment. Polyp samples were collected by outpatient biopsy and analyzed through light microscopy after dyeing with hematoxylin-eosin. RESULTS: Samples were classified in the following way: Edematous or eosinophilic polyp 65 cases (73%); fibro-inflammatory polyp: 16 cases (18%); Polyp with Sero-mucinose gland hyperplasia: 06 cases (6.7%) and polyp with stroma atypia: 2 cases (2.3%). DISCUSSION: eosinophilic pattern prevailed in the patients with nasosinusal polyps of the population studied. This pattern is similar to the ones found in the major studies, which, however, do not mention prior treatment. CONCLUSION: after analyzing the polyps' histological characteristics, we noticed that the untreated polyps present a predominantly eosinophilic pattern.

ABSTRACT

Estudo de coorte contemporânea com corte transversal. As diferenças histológicas dos pólipos nasais e a sua possível implicação clínica são escassas em literatura, apesar de sua importância para um diagnóstico preciso. Os trabalhos existentes classificam amostras de pólipos sem a preocupação quanto à influência de tratamentos prévios, o que influenciaria o resultado obtido. OBJETIVO: Estudar morfologicamente, através da microscopia ótica, as alterações estruturais do pólipo nasal na ausência de qualquer tratamento prévio e classificá-lo, histologicamente, correlacionando com os estudos de literatura. MATERIAL E MÉTODOS: Foram estudados 89 pacientes com polipose rinossinusal sem tratamento prévio. As amostras dos pólipos foram colhidas por biópsia ambulatorial e analisadas através de microscopia ótica após coloração com hematoxilina e eosina. RESULTADOS: As amostras foram classificadas da seguinte forma: pólipo Edematoso ou Eosinofílico: 65 casos (73 por cento); pólipo Fibroinflamatório: 16 casos (18 por cento); pólipo com Hiperplasia de Glândulas Seromucinosas: 06 casos (6,7 por cento) e pólipo com Atipia de Estroma: 2 casos (2,3 por cento). DISCUSSÃO: O padrão eosinofílico predominou nos pacientes com polipose rinossinusal na população estudada. Este padrão assemelha-se com os principais estudos que, no entanto não mencionam sobre tratamentos prévios. CONCLUSÃO: Após análise das características histológicas dos pólipos, observou-se que pólipos não tratados apresentam um padrão predominantemente eosinofílico.

ABSTRACT

OBJETIVO: Avaliar os efeitos do subgalato de bismuto (SGB) usado na área cruenta pós-hepatectomia parcial, quanto a sangramento, aderências e estudo histológico. MÉTODO: Foram utilizados 30 ratos divididos em dois grupos iguais,submetidos à hepatectomias parciais com bisturi de lâmina. Para realizar a hemostasia no grupo 1 (G1), foi utilizado bisturi eletrônico e no grupo 2 (G2), SGB. No 7° dia de pós-operatório (PO), os animais foram mortos, e na cavidade abdominal foram observados sangramento, aderências e, a seguir, realizada a hepatectomia total englobando todos os tecidos adjacentes para análise histológica. No estudo histológico foram analisados: trombose da microcirculação, reação granulomatosa, necrose, fibrose, grau de inflamação e aderências. RESULTADOS: Não foi observado sangramento no PO nos dois grupos. No G1 estavam presentes aderências de omento ao fígado, consideradas neste trabalho como fisiológicas em 80 por cento dos ratos, e no G2 estas aderências foram por outros órgãos, consideradas neste trabalho como anômalas em todos os casos. No exame histológico, quanto à reação granulomatosa e aderências, todos os ratos as apresentaram. Quanto à trombose e necrose o G1 apresentou maior intensidade. Quanto à fibrose e grau de inflamação os resultados foram semelhantes em ambos os grupos. CONCLUSÕES: Ambos os métodos são eficientes para prevenir hemorragia. O G2 apresentou aderências anômalas inviabilizando seu uso em humanos. O G1 revelou mais trombose e necrose. Quanto à reação granulomatosa, fibrose, grau de inflamação e aderências microscópicas, os resultados foram iguais nos dois grupos.


BACKGROUND: This study aimed to observe the effects of bismuth subgallate used on bleeding surfaces after hepatectomy, in relation to bleeding, adhesions and histological study. METHODS: A total of 30 rats divided in 2 equal groups were studied. Partial hepatectomy was performed in both groups. In group 1 (G-1) an electric scalpel was used and in group 2 (G-2) bismuth subgallate for hemostasis of the bloody surface was aplied. On the 7th post-operative day, rats were sacrificed and the abdominal cavity was investigated with respect to bleeding and adhesions. A total hepatectomy with the adhesions was performed for histological study. In the histological study, microcirculation thrombosis, granulomatosis reaction, necrosis, fibrosis, degree of inflammation and adhesions were analyzed. RESULTS: There was no post-operative bleeding in both groups. Adhesions were observed on all rats in both groups. G-1 presented omentum adhesions to the liver, here denominated physiological in 80 percent of the rats and the G-2 presented adhesions of other organs, here named pathological in all cases. The histological study showed that all rats presented a granulomatosis reaction and adhesions. G-1 presented a greater intensity of thrombosis and necrosis. There was no significant difference between the two groups in relation to fibrosis or the degree of inflammation. CONCLUSION: This study demonstrated that both methods were efficient to prevent hemorrhage. G-2 presented pathological adhesions suggesting its use is unfeasible in human beings. G-1 presented more thrombosis and also more necrosis. The granulomatosis reaction, fibrosis, degree of inflammation and microscopic adhesions were similar in between groups.

ABSTRACT

A fibronectina é uma glicoproteína presente no plasma sangüíneo e nos tecidos. Tem propriedade de ligar-se a si mesma e a várias outras substâncias diferentes, tais como a fibrina, a heparina, bactérias, colágeno, fibroblastos, e outras células. Por esta propriedade ligante, desempenha funções fisiológicas múltiplas e tem participação importante em diversos processos patológicos, tanto em sua forma intacta como pela presença de seus isômeros e fragmentos. Fisiologicamente, a fibronectina é responsável pela orientação da migração celular na embriogênese e participa na homeostase e a coagulação sangüínea e na condrogênese. A fibronectina está envolvida em processos osteoartríticos, na produção de anomalias nos membros e em condições patológicas que afetam a mucosa oral humana
