RESUMO
Este relato de caso aborda o curso clínico de um envenenamento botrópico ocorrido no município de Jarinu, SP, no ano de 2021. O paciente necessitou de fasciotomia em membro superior após síndrome compartimental aguda com enxertia dermoepidérmica em um segundo momento cirúrgico. No pós-operatório tardio, o paciente evoluiu com retração, necessitando de reabordagem cirúrgica com correção de retração de membro superior esquerdo. Discute-se a gravidade do acidente ofídico, efeitos do veneno nos tecidos, complicações, síndrome compartimental aguda, indicação e técnica da fasciotomia descompressiva com base na literatura.
This case study examines the clinical course of a Bothrops snakebite poisoning that occurred in Jarinu, São Paulo, Brazil, in 2021. The patient required a fasciotomy in the upper limb due to acute compartment syndrome, followed by a second surgical procedure involving dermo-epidermal grafting. In the late postoperative period, the patient experienced retraction, leading to a subsequent surgical intervention to correct the retraction in the left upper limb. The severity of the snakebite accident, the effects of venom on tissues, complications, acute compartment syndrome, as well as the indications and techniques for decompressive fasciotomy, are discussed based on the available literature.
RESUMO
BACKGROUND & AIMS: Creatine is a dietary supplement with potential capacity to stimulate the phosphocreatine pathway and protein synthesis, through the stimulation of the PI3-K/AKT and mTOR cascade, its use in populations with reduced muscle preservation capacity (such as the older adults) can be an interesting and low-cost alternative. The aim of the present study was to evaluate the morphological, stereological and morphometric effects of the use of creatine monohydrate for 8 weeks on the renal, hepatic and muscular tissues of 26-month-old Wistar rats. METHODS: Twelve Wistar rats were divided into two groups of six animals each. Group 1 was not supplemented with creatine and received a standard diet consisting of water and chow. Group 2 received the same diet, but was supplemented with creatine monohydrate at a dose of 0.3 mg/kg of body weight diluted in 200 ml of drinking water for 8 weeks. RESULTS: Supplementation reduced muscle mass loss as indicated by the perimeter of the perimysium (group 1: 114.6 µm; group 2: 65.2 µm) and endomysium (group 1: 41,239.3 µm; group 2: 12,437.6 µm) compared to the non-supplemented group. In addition, a larger cross-sectional area was observed in group 2. No significant kidney or liver damage was observed in the supplemented group. CONCLUSIONS: The use of creatine is considered safe in the animal model used, as this amine does not cause glomerular reductions or hepatic degeneration.
