REVIEW
Ashish Francis, Richard Baynosa
Ischaemia-induced tissue injury has wide-ranging clinical implications including myocardial infarction, stroke, compartment syndrome, ischaemic renal failure and replantation and revascularization. However, the restoration of blood flow produces a 'second hit' phenomenon, the effect of which is greater than the initial ischaemic event and characterizes ischaemia-reperfusion (IR) injury. Some examples of potential settings of IR injury include: following thrombolytic therapy for stroke, invasive cardiovascular procedures, solid organ transplantation, and major trauma resuscitation...

Revascularization of an amputated limb within 4-6h is essential to avoid extensive ischemia/reperfusion (I/R) injury leading to vascular leakage, edema and tissue necrosis. I/R injury is a pathological inflammatory condition that occurs during reperfusion of an organ or tissue after prolonged ischemia. It is characterized by a complex crosstalk between endothelial cell activation and the activation of plasma cascades. Vasculoprotective pharmacological intervention to prevent I/R injury might be an option to prolong the time window between limb amputation and successful replantation...

BACKGROUND: Nasal tip amputation is a rare but difficult problem to manage. Nonmicrovascular nasal tip replantation is a valid and relatively simple repair option for moderate nasal defects, but tissue ischemia and graft failure occur frequently. CASE REPORT: We present the case of a pediatric nasal tip amputation from a dog bite treated with replantation within 5 hours. The 2.5-cm avulsed tip contained skin, cartilage, and mucosa and was replanted as a 3-layer composite graft...

Tooth avulsion is a type of dental injury defined as the complete displacement of a tooth out of the alveolar socket, and the lack of prompt treatment measures can result in the loss of function, poor quality of life, and psychological and social problems. However, several factors may not permit the immediate replantation of an avulsed tooth; therefore, delayed replantation has emerged as an alternative to meet the esthetic, functional, and psychological demands of patients. Here it was described that the successful replantation of an avulsed maxillary central incisor in a 9-year-old boy who presented at the clinic with the tooth stored in unfavorable conditions as dry and then in olive oil-milk mixture almost 10 h after the event...

Rehmannia glutinosa Libosch. is a medicinal plant cultivated at a commercial scale in China. However, replanting problems result in a severe decline in both the biomass and quality of its roots which are of greatest medicinal value. This study attempted to remediate the replant soil using spent Pleurotus eryngii Quel substrate for alleviating this issue, and to investigate the underlying mechanisms. Results showed that R. glutinosa grew successfully in fresh soil and remedial replant soil, while no roots were harvested in the unremedied replant soil...

Multi-parental populations are promising tools for identifying quantitative disease resistance loci. Stem rot caused by Ganoderma boninense is a major threat to palm oil production, with yield losses of up to 80% prompting premature replantation of palms. There is evidence of genetic resistance sources, but the genetic architecture of Ganoderma resistance has not yet been investigated. This study aimed to identify Ganoderma resistance loci using an oil palm multi-parental population derived from nine major founders of ongoing breeding programs...

INTRODUCTION: Previous occasional successes after delayed replantation suggest that the presence of viable cells may not be the only factor for successful periodontal regeneration in delayed replantation. Various other factors such as proteins or the extracellular matrix (ECM) may play a role in this process. The purpose of this study was to characterize changes in the proteome components of periodontal ligament (PDL) tissue after hypothermic preservation of the tooth. METHODS: Extracted teeth were divided into 4 groups: immediate sampling, sampling after 1 week of preservation at 4°C, sampling after 2 weeks of preservation at 4°C, and sampling after 1 week of dry storage at room temperature as a negative control...

BACKGROUND: In the field of experimental facial vascularized composite tissue allotransplantation (VCA), a human auricular subunit model, pedicled on both superficial temporal (STA) and posterior auricular (PAA) arteries was described. Clinical cases of extensive auricular replantation however, suggested that a single artery could perfuse the entire flap. In our study, variants of this single pedicle approach have been studied, aiming to develop a more versatile replantation technique, in which the question of venous drainage has also been addressed...

INTRODUCTION: Ankylosis and disrupted or altered root development are frequent complications associated with intrusive luxation and tooth avulsion lesions. Various forms of treatment have been described according to the severity of the trauma and root development. The literature shows that decoronation is an ideal treatment in cases where replacement resorption occurs. METHODS: Two clinical cases are presented: involving intrusive luxation [15-year-old female patient with an affected maxillary left lateral incisor (2...

The number of venous anastomoses performed during fingertip replantation is one of the most important factors affecting the success of replantation. However, because vessel diameters decrease in the zone 1 level, vessel anastomoses, especially vein anastomoses, are technically difficult and, thus, cannot be performed in most cases. Alternative venous drainage methods are crucial when any reliable vein repair is not possible. In the literature, so many artery-only replantation techniques have been defined, such as arteriovenous anastomoses, forming an arteriovenous or venocutaneous fistula, manual milking and massage, puncturing, and external bleeding via a fishmouth incision and using a medical leech...

BACKGROUND/PURPOSE: An improvement of the blood flow would be beneficial in microvascular upper-extremity reconstruction and in digit replantation. In the present work, skin perfusion changes and their duration due to axillary plexus block were quantified. METHODS: The peripheral blood flow of the upper extremities in 20 patients undergoing trapeziectomy under axillary plexus block was analyzed. RESULTS: Laser Doppler spectrophotometry was used to measure perfusion factors over a 12-h period, with the contralateral hand acting as the control...

REVIEW
Alison M Rasper, Ryan P Terlecki
Penile transplantation is a novel approach to management of penile loss in the developing field of composite tissue allotransplantation (CTA). Prior management for significant penile loss has been free flap phalloplasty with issues related to function, cosmesis, and functional loss from the location of flap harvest. Transplantation has been an evolving field with advancement in CTA over the past several decades leading to the option of penile transplant. Management of penile injury with replantation provided some preliminary groundwork on the technical aspects for penile transplantation...

This case report discusses the successful endodontic treatment of an open apex maxillary right permanent central incisor that had been avulsed and incorrectly replanted in a 7-year-old patient. The tooth was carefully re-extracted followed by cleaning of the alveolar socket and immediate replantation. However, pulp necrosis was diagnosed, and regenerative endodontic treatment was performed. The root canal system was disinfected by passive ultrasonic irrigation with 2.5% sodium hypochlorite. At the first visit, the tooth was repositioned and immobilized with an appropriate semirigid splint...

As potent allelochemicals, phenolic acids are believed to be associated with replanting disease and cause microflora shift and structural disorder in the rhizosphere soil of continuously monocultured Radix pseudostellariae. The transcriptome sequencing was used to reveal the mechanisms underlying the differential response of pathogenic bacterium Kosakonia sacchari and beneficial bacterium Bacillus pumilus on their interactions with phenolic acids, the main allelochemicals in root exudates of R. pseudostellariae in the monoculture system...

Multiple-level amputations of the upper extremity represent a surgical challenge generally only attempted in young patients. This case demonstrates a successful replantation in an elderly woman. The postoperative course was complicated by disseminated intravascular coagulopathy most likely due to inadequate resuscitation. Hand trauma is often underestimated in its general severity. Upper extremity amputations need to be handled similar to polytraumatized patients.

PURPOSE: In January 2006, the American College of Emergency Physicians released updated guidelines for air transfer. Digit amputation and near-amputation were no longer an indication for this costly service. We analyzed the effect of this update on the use of air transport and associated care outcomes for finger amputation patients and examined factors involved in providing follow-up care for these patients. METHODS: A retrospective chart review identified all patients treated for traumatic finger amputation between 1995 and 2012 at a major hand trauma referral center...
