CCS e amiloide A do leite de quartos mamários tratados na secagem com plasma rico em plaquetas autólogo, associado ou não a antibiótico / [CCS and Amyloid A of milk from breast quarters treated in drying with autologous platelet-rich plasma, with or without antibiotics]

Este estudo teve como objetivo avaliar biomarcadores de mastite após terapia da secagem com plasma rico em plaquetas (PRP), associado ou não a antibiótico. Trinta e seis quartos mamários foram utilizados em três tratamentos (T): T1 - antibiótico (ATB), T2 - PRP e T3 - PRP + ATB. Amostras de leite foram coletadas antes da secagem (A1), no parto (D0) e 14, 30 e 60 dias pós-parto (D14, D30 e D60), para determinar contagem de células somáticas (CCS) e amiloide A (AA). O delineamento foi inteiramente ao acaso, com arranjo em parcelas subdivididas (SigmaPlot®). Dados de CCS foram transformados (log 10). As médias foram comparadas utilizando-se testes de Tukey ou Holm-Sidak (P<0,05). A CCS em A1 foi elevada em todos os grupos (P>0,05). No D30, CCS foi maior em T2 (P<0,05), igualando-se no D60. Não houve diferença na AA entre Ts em qualquer dia de coleta (P>0,05). Houve diferença nos momentos de coleta (P<0,05), A1 maior que D14 e D30. Houve uma correlação positiva fraca com CCS (0,280). Os tratamentos foram semelhantes em manter a saúde da glândula mamária na lactação subsequente. O PRP intramamário pode ser usado para terapia de vaca seca em casos de mastite subclínica.(AU)

This study aimed to evaluate biomarkers of mastitis after autologous platelet rich plasma (PRP) dry cow therapy, associated or not with antibiotic, compared to conventional treatment. Thirty-six mammary quarters were used in three treatments (T): T1 - antibiotic, T2 - PRP and T3 - PRP + ATB. Milk samples were collected before drying (A1), on calving (D0) and at 14, 30 and 60 days postpartum (D14, D30 and D60), for Somatic Cell Count (CCS) and amyloid dosage A (AA). The design was completely randomized with arrangement in subdivided plots (SigmaPlot ®). Data from CCS were transformed in log10. Means were compared using the Tukey or Holm-Sidak tests, at a 95% confidence level (P<0.05). CCS in A1 was elevated in allgroups (P>0.05). On D30 CCS was higher in T2 (P<0.05), matching D60. There was no difference in AA among T on any day of collection (P>0.05). There was difference in collection moments (P<0.05), A1 different from D14 and D30. There was a weak positive correlation with CCS (0.280). Three treatments were similar in maintaining the health of the mammary gland at subsequent lactation. PRP intramammary can be used for dry cow therapy in subclinical mastitis.(AU)

Amyloid goitre: a case report.

Amyloid goitre is an exceedingly rare condition associated with a clinically apparent enlargement of the thyroid gland due to massive amyloid infiltration. We hereby report an additional case of this rare entity.

Secondary cutaneous amyloidosis in disseminated superficial porokeratosis: a case report

Disseminated superficial porokeratosis (DSP) is a rare cause of secondary cutaneous amyloidosis. An 83-year-old male patient showed an increase in both size and number of DSP lesions after contracting pulmonary tuberculosis. The DSP lesions of the patient consisted of numerous annular eruptions on both sun-exposed and sun-protected areas, which occurred over a period of 20 years. Multiple skin biopsies were taken from normal or lesional/sun-exposed or sun-protected skin samples. Histopathologic examination included routine H+ACY-E stains, Congo red stains, thioflavin-T stains and anticytokeratin antibodies (AE1, AE3). And the results were as follows+ADs- 1) Positive staining with Congo red and thioflavin-T indicated an amyloid nature for the deposits, 2) confinement of the amyloid deposition just below the lesional epidermis (while sparing the neighboring uninvolved or distant normal skin) indicated some role of the lesional epidermis, and 3) positive staining with AE3 further indicated an epidermal origin-type II epithelial keratin-of the amyloid. We present a case of DSP with a local amyloid deposit, characterized by association of positive familial background, severe pruritus and pulmonary tuberculosis.

Senile systemic amyloidosis--a case report.

An 85 years old female presented with acute pain and weakness in left lower extremity and doppler evidence of femoropopliteal block was made which subsequently proved fatal. Necropsy revealed extensive amyloid deposition in the heart and amyloid angiopathy in rest of the organs.

Responsabilidade do fator hemodinâmico na gênese da síndrome do túnel do carpo nos pacientes hemodialisados / Haemodynamic factor responsibility in the genesis of the carpal tunnel syndrome in haemodialyzed patients

A patologia esquelética representa uma complicaçäo importante no paciente dialisado a longo prazo, sendo numerosas as síndromes clínico-radiológicas de osteoartropatia com ela relacionadas. Entre essas, a síndrome de túnel do carpo é, sem dúvida, a mais importante e frequente. Muitos fatores säo mencionados como responsáveis na gênese da CTS no paciente dialisado crônico. Tendo presente o problema etiopatogênico, até hoje discutido, e considerando alguns dados clínicos verificados em 80 pacientes tratados na Divisäo de Cirurgia Plástica, iniciou-se um estudo com a finalidade de evidenciar o possível papel patogênico do fator hemodinâmico na gênese da síndrome do túnel do carpo no paciente hemodialisado. Os autores, com base nos resultados de um estudo retrospectivo, realizaram um estudo controlado, evidenciando o papel do fator hemodinâmico na gênese da síndrome do túnel do carpo no paciente hemodialisado. Os autores, com base nos resultados de um estudo retrospectivo, realizaram um estudo controlado, evidenciando o papel do fator hemodinâmico sobre os agentes etiológicos, no sentido de facilitar a determinaçäo da síndrome do túnel do carpo

Ampliaçäo do espectro bioquímico da sinovianálise / Broadening the biochemical spectrum of synovial fluid analysis

Os autores avaliaram algumas técnicas bioquímicas (substâncias amilóide, lipídios e lactato), estabelecendo as limitaçöes e aplicaçöes práticas, objetivando melhor aproveitamento do líquido sinovial (LS) nos casos de dúvidas diagnósticas. Apresentam resultados próprios em relaçäo ao lactato e salientam as dificuldades na manipulaçäo do LS, principalmente devido a falta de uniformidade no processo técnico
