ABSTRACT

PURPOSE: To assess collagen content and types in the rectus abdominis muscle of cadavers of different ages. METHODS: Forty fresh adult male cadavers within 24 h of death were obtained from an Institute of Legal Medicine and divided by age at death into Group 1 (mean age, 23.3 years; range, 18-30 years; n = 20) and Group 2 (mean age, 46.2 years; range, 31-60 years; n = 20). From each cadaver, samples of the rectus abdominis muscle measuring 1 cm(2) were collected 3 cm superiorly and 2 cm inferiorly to the umbilicus. Histological sections were prepared and stained with picrosirius red and Masson's trichrome stain for visualization of total collagen fibers, and immunohistochemical analysis was performed to distinguish types I, II, III, IV and V collagen. RESULTS: No significant differences in total collagen were found between groups by Masson's trichrome staining. However, picrosirius red staining revealed a significantly greater amount and higher concentration of total collagen and types I and III collagen in Group 1 than in Group 2 (P < 0.05). All but type II collagen were detected by immunohistochemistry in both groups. No significant difference in type IV collagen was found between groups. Type V collagen was detected by immunohistochemistry in both groups, but quantification was not possible due to background staining. CONCLUSION: The amounts of types I and III collagen in the rectus abdominis muscle were significantly smaller in older subjects.

ABSTRACT

OBJETIVO: Analisar a aplicabilidade do retalho fáscio-cutâneo em V-Y da regiäo posterior da coxa na reparaçäo de lesöes isoladas ou múltiplas nas regiöes glútea e perineal. MÉTODO: Foram submetidos a tratamento cirúrgico 20 pacientes, portadores de 25 úlceras nas regiöes glútea e perineal, sendo 23 delas úlceras por pressäo, um pós-abscesso perianal e um pós-trauma perineal. Em todos os pacientes a reparaçäo foi realizada com o retalho fáscio-cutâneo da regiäo posterior da coxa. O retalho foi confeccionado com base súpero-lateral, preservando-se os ramos fáscio-cutâneos das artérias glútea inferior, primeira e segunda perfurantes no tratamento de úlceras isquiáticas. Nas associaçöes de úlcera isquiática com úlcera sacral, adicionou-se ao retalho uma extensäo fáscio-cutânea da regiäo glútea para tratamento cirúrgico em tempo único. Foi realizado retalho com base súpero-medial, preservando-se o ramo fáscio-cutâneo da artéria glútea inferior no tratamento das úlceras trocantéricas. Nas associaçöes com úlcera sacral, acrescentou-se ao retalho posterior da coxa uma extensäo fáscio-cutânea da regiäo glútea, que permitiu o fechamento de todas as úlceras em um só tempo cirúrgico. Nas associaçöes de úlceras trocantéricas e isquiáticas, realizou-se o retalho com base superior, preservando-se o ramo fáscio-cutâneo da artéria glútea inferior. RESULTADOS: Näo houve necrose do retalho. As complicaçöes imediatas foram três infecçöes, uma deiscência e um hematoma. Num período de seguimento de 6 meses a 29 meses, houve recidiva de seis úlceras (6/24 = 25,0 por cento) em cinco pacientes (5/19 = 26,32 por cento). Um paciente foi perdido neste seguimento. CONCLUSÄO: Conclui-se que o retalho fáscio-cutâneo posterior da coxa, em V-Y, pode ser utilizado com segurança no tratamento de lesöes isoladas ou múltiplas das regiöes glútea e perineal

ABSTRACT

PURPOSE: To analyze the clinical applicability of one-stage treatment of single or multiple sores using the V-Y posterior thigh fasciocutaneous flap. METHODS: Twenty patients were treated, having 25 ulcers in the gluteal and perineal regions, being 23 pressure ulcers, 1 perianal abscess and 1 perineal trauma. In all of the patients the repair was carried out with a fasciocutaneous flap from the posterior region of the thigh. The flap was made with a superior and lateral base, preserving the fasciocutaneous branches of the inferior gluteal arteries, first and second perforating, in the treatment of ischial ulcers. In the associations of the same with sacral ulcer, a fasciocutaneous extension from the gluteal region was added to the flap for a one and only surgical procedure. A superior and medial based flap was made, preserving the fasciocutaneous branch of the inferior gluteal artery in the treatment of the trochanteric ulcers. In the associations with sacral ulcer a fasciocutaneous extension from the gluteal region was added to the posterior thigh flap which permitted the closure of all ulcers in only one surgical procedure. In the associations of trochanteric and ischial ulcers a flap with a superior base was made, preserving the fasciocutaneous branch of the inferior gluteal artery. RESULTS: There was no necrosis of the flap. The immediate complications were 3 infections, 1 dehiscences and 1 hematoma. In a follow-up period of 6 months to 29 months, with one patient being lost to follow up, there were 6 recurrences 6/24 (25.0%) in 5 patients 5/19 (26.32%). CONCLUSION: We conclude that the posterior fasciocutaneous thigh flap, in V-Y, can be used with safety in the treatment of isolated or multiple ulcers in the gluteal and perineal regions.

ABSTRACT

Os resultados de um estudo multicêntrico, aberto e nåo comparativo, no qual foram avalaiados 150 pacientes com diagnóstico de depressåo maior de acordo com os critérios da DSM-III-R, såo relatados. Os pacientes selecionados foram inicialmente submetidos a um período simples-cego, durante 2 semanas. Após essa fase, aqueles que preenchiam os critérios de inclusåo e exclusåo iniciaram o tratamento com sertralina 50mg/dia que poderia ser aumentada gradualmente até 200mg/dia, incrementos de 50mg, e intervalos de no mínimo 2 semanas, caso a resposta ao tratamento fosse insatisfatória, segundo a avaliaçåo do investigador. O tratamento com sertalina mostrou-se altamente eficaz no alívio da depressåo. como também nos sintomas associados ao quadro depressivo como, ansiedade, transtornos do sono, agitaçåo ou inibiçåo psicomotora, trabalho e atividades, entre outros. Um total de 84,2 por cento dos pacientes responderam satisfatoriamente ao tratamento com sertralina em doses felíveis. Em relaçåo à tolerabilidade, um total de 54 por cento dos pacientes apresentaram algum efeito adverso ao longo do tratamento, porém estes efeitos foram geralmente de intensidade leve ou moderada e apenas 4,6 por cento dos pacientes interromperam o tratamento prematuramente devido à ocorrência de eventos adversos
