BACKGROUND: Digital replantation has become a well-established technique that has revolutionized hand surgery. One of the most important factors to a successful replantation is less than 12 hours of warm and 24 hours of cold ischemia time. The purpose of this article was to present a concept of door-to-surgery time and test the hypothesis that success in distal digital replantation is associated with this time. METHODS: Forty-five patients with 49 distal amputations were included in the study...

INTRODUCTION: While published data on functional outcomes after upper limb amputations are plentiful, epidemiology data are relatively rare. This led us to performing an epidemiology study of traumatic upper limb amputations at our facility. MATERIAL AND METHODS: This retrospective study spanned a 10-year period of cases seen at the SOS Main (Hand emergency center) of the Nancy University Hospital in France. Patients who suffered traumatic amputation of the upper limb were identified and divided into two groups: replantation and surgical amputation...

Various medicinal plants are threatened with extinction owing to their over-exploitation and the prevalence of soil borne pathogens. In this study, soils infected with root-rot pathogens, which prevent continuous-cropping, were treated with an electron beam. The level of soil-borne fungus was reduced to ≤0.01% by soil electron beam treatment without appreciable effects on the levels of antagonistic microorganism or on the physicochemical properties of the soil. The survival rate of 4-year-old plant was higher in electron beam-treated soil (81...

Cold intolerance is a common complication of digital replantation. The exact etiology is unclear, but it is considered to be multifactorial, including nonsurgical characteristics, vascular, and neurologic conditions. Blood flow may play a significant role in cold intolerance. This study was designed to evaluate the correlation of digital blood flow, including volumetric flow rate (VFR) and skin blood flow (SkBF), with cold intolerance in replanted fingers.A retrospective study was conducted among patients who underwent digital replantation between 2010 and 2013...

Identifying and quantifying the importance of environmental variables in structuring population genetic variation can help inform management decisions for conservation, restoration, or reforestation purposes, in both current and future environmental conditions. Landscape genomics offers a powerful approach for understanding the environmental factors that currently associate with genetic variation, and given those associations, where populations may be most vulnerable under future environmental change. Here, we applied genotyping by sequencing to generate over 11,000 single nucleotide polymorphisms from 311 trees and then used nonlinear, multivariate environmental association methods to examine spatial genetic structure and its association with environmental variation in an ecologically and economically important tree species endemic to Hawaii, Acacia koa...

Our subject is a 36-year-old man who presented to the emergency department with bilateral lower extremity amputation at the level of the distal third of the tibia after a car accident. Surgery was planned for below-knee amputation of the right lower extremity and replantation of the left foot. The arteries dissected from the iatrogenically amputated segment were used as grafts to repair vascular gaps during the replantation. The patient's follow-up had been problem free. We concluded that whenever possible, amputated parts unsuitable for replantation should be examined thoroughly and neurovascular structures that might be used as grafts should be preserved...

The transcriptome profiling in replanting roots revealed that expression pattern changes of key genes promoted important metabolism pathways, antioxidant and pathogen defense systems, adjusted phytohormone signaling and inhibited lignin biosynthesis. The yield of the medicinal plant Achyranthes bidentata could be significantly increased when replanted into a field cultivated previously for the same crop, but the biological basis of this so-called "replanting benefit" is unknown. Here, the RNA-seq technique was used to identify candidate genes responsible for the benefit...

Replacement resorption is the most frequent complication after delayed replantation of avulsed teeth. The resorption can interfere with the development of the alveolar ridge and lead to tilt of the adjacent teeth in growing patients. However, there is no means of arresting or reversing the process. Recently decoronation is recommended by International Assocaition of Dental Traumatology as the optimal choice to manage it. This paper demonstrates the procedure and effectiveness of the decoronation by literature review and a case report with 4-year follow-up...

BACKGROUND: Traumatic tooth avulsion requires an urgent intervention to replant the tooth. Prolonged post-injury dry extra-oral conditions worsen the prognosis and increase the risk of root resorption. Fluoride has the potential to delay replacement resorption. Calcium silicate cements (CSC) are used to seal the root canal system and to stimulate periapical regeneration in immature open apex teeth (apexification). This report suggests the application of a novel fast-setting CSC with fluoride for apexification in an attempt to hinder root resorption...

Successful replantation of distal digital segments necessitates the establishment of sufficient outflow to minimize congestion and progressive tissue necrosis. In cases where only arterial anastomosis is feasible, an artificial outlet must be provided to maintain physiological requirements until microvenous circulation regenerates. This can be accomplished using any number of "exsanguination techniques" designed to facilitate egress through ongoing passive blood loss. Although reportedly effective, these measures are imprecise and carry a substantial risk of infection, scarring, and/or uncontrolled hemorrhage...
