Management of acute peripheral arterial injury by using doppler ultrasonography

Objective To determine the effectiveness of the duplex ultrasonography scanning in the management acute peripheral arterial injury. Materials and methods Its a prospective evaluation comparing duplex scanning with operative exploration finding in 78 patients.Duplex scan was used alone for 98 patients having clinical finding of acute vascular insufficiency. Results Duplex scanning had 100% sensitivity and 95.23% specificity compared with operative exploration in the 78 cases. Duplex scanning detected 78 injuries, 77 of which were confirmed by correlation with operative exploration and 20 patients did not have vascular injury. One false-positive result was due to spasm of the superficial femoral artery. Conclusions Duplex scanning is a noninvasive, safe, effective , rapid and lesion localising method of initial evaluation for acute peripheral vascular injury having clinical features of vascular insufficiency.

A lethal chest injury following rhinoceros attack– a case report

Injuries following wild animal encounters continue to be a major public health problem. Majority of such injuries are minor, however, many injuries remain undocumented. Many victim die, primarily in third-world countries, before receiving adequate medical care. Penetrating injuries to the chest following the attack by the wild animals, though rare, present a challenging problem. Though a great number of papers have been published regarding the injuries following encounter with animals, least are the lethal injuries occuring in the thoracic region and the survival out of these grave injury is very minimum. We herein present the least possible surviving case with lethal penetrating injury of the chest and left lung following the goring by the rhinoceros.

Removal and monitoring acetaminophen-contaminated hospital wastewater by vertical flow constructed wetland and peroxidase enzymes

© 2019 Elsevier Ltd Hospital wastewater contains acetaminophen (ACT) and nutrient, which need adequate removal and monitoring to prevent impact to environment and community. This study developed a pilot scale vertical flow constructed wetland (CW) to (1) remove high-dose ACT and pollutants in hospital wastewater and (2) identify the correlation of peroxidase enzyme extruded by Scirpus validus and pollutants removal efficiency. By that correlation, a low-cost method to monitor pollutants removal was drawn. Plants, such as Scirpus validus, generated peroxidase enzymes to alleviate pollutants’ stress. Results showed that the CW removed 3.5 to 6 logs of initial concentration 10 mg ACT/L to a recommended level for drinking water. The CW eliminated COD, TKN and TP efficiently, meeting the wastewater discharged standards of Thailand and Vietnam. By various multivariable regression models, concentrations of ACT in CW effluent and enzymes in S. validus exhibited a significant correlation (p < 0.01, R2 = 68.3%). These findings suggested that (i) vertical flow CW could remove high-dose ACT and nutrient and (ii) peroxidase enzymes generated in S. validus, such as soluble and covalent ones, could track ACT removal efficiency. This would help to reduce facilities and analytical cost of micro-pollutants
