Epilepsy: knowledge and attitudes of physiotherapists, occupational therapists, and speech therapists.

Physiotherapists, occupational therapists, and speech therapists play a key role in the treatment of children with epilepsy. We performed a survey of therapists' knowledge of and attitudes towards epilepsy in two regions of Germany, the city of Leipzig and the rural district of Zwickau. Therapists of 29/68 (43%) outpatient practices and 4/9 (44%) hospitals took part. In total, 195 therapists participated: 63 (32%) physiotherapists, 74 (38%) occupational therapists, and 58 (30%) speech therapist. In 65%, epilepsy was subject of vocational training. Of all therapists, 8% claimed they had not treated epilepsy patients so far. During professional life, 43% had witnessed a seizure. Of all therapists, 44% correctly assumed a seizure could result in death. During a seizure, 42% would perform the obsolete measure of placing something solid in the patient's mouth, and 41% would administer a prescribed rescue medication. More information on epilepsy was requested by 92%.Conclusion: Most therapists treat patients with epilepsy, and almost half have already witnessed a seizure. Often, however, epilepsy is not subject of vocational training. The risk of a fatal outcome of a seizure is underestimated, and many therapists would perform obsolete measures. Knowledge of seizure management should be transmitted to therapists especially during vocational training.

Emergency Department Intubation Success With Succinylcholine Versus Rocuronium: A National Emergency Airway Registry Study.

STUDY OBJECTIVE: Although both succinylcholine and rocuronium are used to facilitate emergency department (ED) rapid sequence intubation, the difference in intubation success rate between them is unknown. We compare first-pass intubation success between ED rapid sequence intubation facilitated by succinylcholine versus rocuronium. METHODS: We analyzed prospectively collected data from the National Emergency Airway Registry, a multicenter registry collecting data on all intubations performed in 22 EDs. We included intubations of patients older than 14 years who received succinylcholine or rocuronium during 2016. We compared the first-pass intubation success between patients receiving succinylcholine and those receiving rocuronium. We also compared the incidence of adverse events (cardiac arrest, dental trauma, direct airway injury, dysrhythmias, epistaxis, esophageal intubation, hypotension, hypoxia, iatrogenic bleeding, laryngoscope failure, laryngospasm, lip laceration, main-stem bronchus intubation, malignant hyperthermia, medication error, pharyngeal laceration, pneumothorax, endotracheal tube cuff failure, and vomiting). We conducted subgroup analyses stratified by paralytic weight-based dose. RESULTS: There were 2,275 rapid sequence intubations facilitated by succinylcholine and 1,800 by rocuronium. Patients receiving succinylcholine were younger and more likely to undergo intubation with video laryngoscopy and by more experienced providers. First-pass intubation success rate was 87.0% with succinylcholine versus 87.5% with rocuronium (adjusted odds ratio 0.9; 95% confidence interval 0.6 to 1.3). The incidence of any adverse event was also comparable between these agents: 14.7% for succinylcholine versus 14.8% for rocuronium (adjusted odds ratio 1.1; 95% confidence interval 0.9 to 1.3). We observed similar results when they were stratified by paralytic weight-based dose. CONCLUSION: In this large observational series, we did not detect an association between paralytic choice and first-pass rapid sequence intubation success or peri-intubation adverse events.

Emergency Dental Treatment of a Patient With Sturge-Weber Syndrome.

The Sturge-Weber (SWS) syndrome is a rare condition with congenital capillary malformations. Hemorrhages may occur on dental treatment, which can have a dramatic effect on a patient's vital sign. The aim of the present brief clinical study was to briefly report a case of a female patient with SWS who underwent an endodontic treatment. A 25-year-old patient (C.O.B.S.) with SWS and vascular malformation in cervicofacial right region was admitted to the dental clinic with pulsatile pain in tooth 16. An emergency dental treatment with cavity preparation and access to root canals was performed with intraligamentary and intrapulpal anesthesia with 3% prilocain 3% with felypressin 0.03 UI/mL because the tooth was located in the region of the vascular malformation, and any surgical treatment could lead to hemorrhages. After 7 days, the patient was recalled with the absence of painful symptoms. The endodontic treatment in patients with SWS is feasible, and safety should be an alternative to surgical treatments.

Medical emergencies in the dental surgery. Part 1: Preparation of the office and basic management.

STATEMENT OF THE PROBLEM: Medical emergencies can and do happen in the dental surgery. In the 20- to 30-year practice lifetime of the typical dentist, he/she will encounter between five and seven emergency situations. Being prepared in advance of the emergency increases the likelihood of a successful outcome. PURPOSE OF THE PAPER: To prepare members of the dental office staff to be able to promptly recognize and efficiently manage those medical emergency situations that can occur in the dental office environment. MATERIALS AND METHODS: Preparation of the dental office to promptly recognize and efficiently manage medical emergencies is predicated on successful implementation of the following four steps: basic life support for ALL members of the dental office staff; creation of a dental office emergency team; activation of emergency medial services (EMS) when indicated; and basic emergency drugs and equipment. The basic emergency algorithm (P->C->A->B->D) is designed for implementation in all emergency situations. RESULTS AND CONCLUSIONS: Prompt implementation of the basic emergency management protocol can significantly increase the likelihood of a successful result when medical emergencies occur in the dental office environment.

Emergency drug kits: pharmacological and technical considerations.

The risk for complications while providing dental procedures is greatest when caring for patients having significant medical compromise. It is comforting that significant adverse events can generally be prevented by careful preoperative assessment, along with attentive intraoperative monitoring and support. Nevertheless, the office team must be prepared to manage untoward events should they arise. This continuing education article will address basic emergency drugs that should be available in all dental practices and additional agents that become essential for those practices providing various levels of procedural sedation or general anesthesia.

[International Association of Dental Traumatology guidelines for the management of traumatic dental injuries: 2. Avulsion of permanent teeth. Hebrew edition].

Avulsion of permanent teeth is one of the most serious dental injuries, and a prompt and correct emergency management is very important for the prognosis. The International Association of Dental Traumatology (IADT) has developed a consensus statement after a review of the dental literature and group discussions. Experienced researchers and clinicians from various specialties were included in the task group. The guidelines represent the current best evidence and practice based on literature research and professionals' opinion. In cases where the data did not appear conclusive, recommendations were based on the consensus opinion or majority decision of the task group. Finally, the IADT board members were giving their opinion and approval. The primary goal of these guidelines is to delineate an approach for the immediate or urgent care of avulsed permanent teeth. The Hebrew Edition is part of the IADT global effort to provide a worldwide accessibility to these guidelines. This scond part of the guidelines will focus on avulsion of permanent teeth.

[International Association of Dental Traumatology guidelines for the management of traumatic dental injuries: 3. Injuries in the primary dentition. Hebrew edition].

Traumatic injuries to the primary dentition present special problems and the management is often different as compared with the permanent dentition. The International Association of Dental Traumatology (IADT) has developed a consensus statement after a review of the dental literature and group discussions. Experienced researchers and clinicians from various specialities were included in the task group. In cases where the data did not appear conclusive, recommendations were based on the consensus opinion or majority decision of the task group. Finally, the IADT board members were giving their opinion and approval. The primary goal of these guidelines is to delineate an approach for the immediate or urgent care for management of primary teeth injuries. The IADT cannot and does not guarantee favorable outcomes from strict adherence to the guidelines, but believe that their application can maximize the chances of a positive outcome. The Hebrew Edition is part of the IADT global effort to provide a worldwide accessibility to these guidelines. This third part will discuss injuries in the primary dentition.

American Medical Society for Sports Medicine position statement: concussion in sport.

PURPOSE OF THE STATEMENT: ▸ To provide an evidence-based, best practises summary to assist physicians with the evaluation and management of sports concussion. ▸ To establish the level of evidence, knowledge gaps and areas requiring additional research. IMPORTANCE OF AN AMSSM STATEMENT: ▸ Sports medicine physicians are frequently involved in the care of patients with sports concussion. ▸ Sports medicine physicians are specifically trained to provide care along the continuum of sports concussion from the acute injury to return-to-play (RTP) decisions. ▸ The care of athletes with sports concussion is ideally performed by healthcare professionals with specific training and experience in the assessment and management of concussion. Competence should be determined by training and experience, not dictated by specialty. ▸ While this statement is directed towards sports medicine physicians, it may also assist other physicians and healthcare professionals in the care of patients with sports concussion. DEFINITION: ▸ Concussion is defined as a traumatically induced transient disturbance of brain function and involves a complex pathophysiological process. Concussion is a subset of mild traumatic brain injury (MTBI) which is generally self-limited and at the less-severe end of the brain injury spectrum. PATHOPHYSIOLOGY: ▸ Animal and human studies support the concept of postconcussive vulnerability, showing that a second blow before the brain has recovered results in worsening metabolic changes within the cell. ▸ Experimental evidence suggests the concussed brain is less responsive to usual neural activation and when premature cognitive or physical activity occurs before complete recovery the brain may be vulnerable to prolonged dysfunction. INCIDENCE: ▸ It is estimated that as many as 3.8 million concussions occur in the USA per year during competitive sports and recreational activities; however, as many as 50% of the concussions may go unreported. ▸ Concussions occur in all sports with the highest incidence in football, hockey, rugby, soccer and basketball. RISK FACTORS FOR SPORT-RELATED CONCUSSION: ▸ A history of concussion is associated with a higher risk of sustaining another concussion. ▸ A greater number, severity and duration of symptoms after a concussion are predictors of a prolonged recovery. ▸ In sports with similar playing rules, the reported incidence of concussion is higher in female athletes than in male athletes. ▸ Certain sports, positions and individual playing styles have a greater risk of concussion. ▸ Youth athletes may have a more prolonged recovery and are more susceptible to a concussion accompanied by a catastrophic injury. ▸ Preinjury mood disorders, learning disorders, attention-deficit disorders (ADD/ADHD) and migraine headaches complicate diagnosis and management of a concussion. DIAGNOSIS OF CONCUSSION: ▸ Concussion remains a clinical diagnosis ideally made by a healthcare provider familiar with the athlete and knowledgeable in the recognition and evaluation of concussion. ▸ Graded symptom checklists provide an objective tool for assessing a variety of symptoms related to concussions, while also tracking the severity of those symptoms over serial evaluations. ▸ Standardised assessment tools provide a helpful structure for the evaluation of concussion, although limited validation of these assessment tools is available. SIDELINE EVALUATION AND MANAGEMENT: ▸ Any athlete suspected of having a concussion should be stopped from playing and assessed by a licenced healthcare provider trained in the evaluation and management of concussions. ▸ Recognition and initial assessment of a concussion should be guided by a symptoms checklist, cognitive evaluation (including orientation, past and immediate memory, new learning and concentration), balance tests and further neurological physical examination. ▸ While standardised sideline tests are a useful framework for examination, the sensitivity, specificity, validity and reliability of these tests among different age groups, cultural groups and settings is largely undefined. Their practical usefulness with or without an individual baseline test is also largely unknown. ▸ Balance disturbance is a specific indicator of a concussion, but not very sensitive. Balance testing on the sideline may be substantially different than baseline tests because of differences in shoe/cleat-type or surface, use of ankle tape or braces, or the presence of other lower extremity injury. ▸ Imaging is reserved for athletes where intracerebral bleeding is suspected. ▸ There is no same day RTP for an athlete diagnosed with a concussion. ▸ Athletes suspected or diagnosed with a concussion should be monitored for deteriorating physical or mental status. NEUROPSYCHOLOGICAL TESTING: ▸ Neuropsychological (NP) tests are an objective measure of brain-behaviour relationships and are more sensitive for subtle cognitive impairment than clinical exam. ▸ Most concussions can be managed appropriately without the use of NP testing. ▸ Computerised neuropsychological (CNP) testing should be interpreted by healthcare professionals trained and familiar with the type of test and the individual test limitations, including a knowledgeable assessment of the reliable change index, baseline variability and false-positive and false-negative rates. ▸ Paper and pencil NP tests can be more comprehensive, test different domains and assess for other conditions which may masquerade as or complicate assessment of concussion. ▸ NP testing should be used only as part of a comprehensive concussion management strategy and should not be used in isolation. ▸ The ideal timing, frequency and type of NP testing have not been determined. ▸ In some cases, properly administered and interpreted NP testing provides an added value to assess cognitive function and recovery in the management of sports concussions. ▸ It is unknown if use of NP testing in the management of sports concussion helps prevent recurrent concussion, catastrophic injury or long-term complications. ▸ Comprehensive NP evaluation is helpful in the post-concussion management of athletes with persistent symptoms or complicated courses. RETURN TO CLASS: ▸ Students will require cognitive rest and may require academic accommodations such as reduced workload and extended time for tests while recovering from a concussion. RETURN TO PLAY: ▸ Concussion symptoms should be resolved before returning to exercise. ▸ A RTP progression involves a gradual, step-wise increase in physical demands, sports-specific activities and the risk for contact. ▸ If symptoms occur with activity, the progression should be halted and restarted at the preceding symptom-free step. ▸ RTP after concussion should occur only with medical clearance from a licenced healthcare provider trained in the evaluation and management of concussions. SHORT-TERM RISKS OF PREMATURE RTP: ▸ The primary concern with early RTP is decreased reaction time leading to an increased risk of a repeat concussion or other injury and prolongation of symptoms. LONG-TERM EFFECTS: ▸ There is an increasing concern that head impact exposure and recurrent concussions contribute to long-term neurological sequelae. ▸ Some studies have suggested an association between prior concussions and chronic cognitive dysfunction. Large-scale epidemiological studies are needed to more clearly define risk factors and causation of any long-term neurological impairment. DISQUALIFICATION FROM SPORT: ▸ There are no evidence-based guidelines for disqualifying/retiring an athlete from a sport after a concussion. Each case should be carefully deliberated and an individualised approach to determining disqualification taken. EDUCATION: ▸ Greater efforts are needed to educate involved parties, including athletes, parents, coaches, officials, school administrators and healthcare providers to improve concussion recognition, management and prevention. ▸ Physicians should be prepared to provide counselling regarding potential long-term consequences of a concussion and recurrent concussions. PREVENTION: ▸ Primary prevention of some injuries may be possible with modification and enforcement of the rules and fair play. ▸ Helmets, both hard (football, lacrosse and hockey) and soft (soccer, rugby) are best suited to prevent impact injuries (fracture, bleeding, laceration, etc.) but have not been shown to reduce the incidence and severity of concussions. ▸ There is no current evidence that mouth guards can reduce the severity of or prevent concussions. ▸ Secondary prevention may be possible by appropriate RTP management. LEGISLATION: ▸ Legislative efforts provide a uniform standard for scholastic and non-scholastic sports organisations regarding concussion safety and management. FUTURE DIRECTIONS: ▸ Additional research is needed to validate current assessment tools, delineate the role of NP testing and improve identification of those at risk of prolonged post-concussive symptoms or other long-term complications. ▸ Evolving technologies for the diagnosis of concussion, such as newer neuroimaging techniques or biological markers, may provide new insights into the evaluation and management of sports concussion.

Complications and survival rates of teeth after dental trauma over a 5-year period.

OBJECTIVES: The purpose of this study was to evaluate whether the current guidelines of the International Association of Dental Traumatology (IADT) for emergency care of traumatised teeth result in lower complication rates. MATERIALS AND METHODS: Therapeutic strategies of 361 dental injuries in 291 patients treated at a university dental hospital over a 5-year period were investigated by evaluating the patients' records. Adherence to the guidelines of the IADT (Flores et al. Dent Traumatol 17:1-4, 2001; 49-52, 2001; 97-102, 2001; 145-148, 2001; and 193-196, 2001; Flores et al. Dent Traumatol 23:66-71, 2007; 130-136, 2007; and 196-202, 2007) was evaluated. Complications were also recorded according to the patients' records and analysed relative to the treatment and injury pattern. During follow-up visits, the teeth were inspected regarding pulp vitality and overall function of the injured tooth. The Kaplan-Meier survival analysis of pulps and teeth was performed for different injury categories. RESULTS: The majority of injuries (322/361; 89.2 %) were treated according to the guidelines. When IADT guidelines were followed, complication rates were significantly lower than for cases treated without adherence to the guidelines. The most frequent complication was the loss of restoration, followed by pulp necrosis, abnormal mobility, and tooth loss. The overall survival analysis showed that in the permanent dentition, the loss of pulp vitality and tooth occurs within the first 6 months but may also occur later. CONCLUSIONS: The results of this study indicate that traumatised teeth that were treated according to the recommendations had a lower complication rate. In addition, the majority of pulp necrosis and tooth losses in the permanent dentition occurred within the first 6 months after trauma. These results indicate that early follow-up visits are essential to promptly treat complications. CLINICAL RELEVANCE: Adherence to the IADT guidelines for treatment of dental trauma may lead to more favourable outcomes when compared to cases treated without compliance to the guidelines.

Oxylator and SCUBA dive regulators: useful utilities for in-water resuscitation.

INTRODUCTION: In water resuscitation has been reported to enhance the outcome of drowning victims. Mouth-to-mouth ventilation during swimming is challenging. Therefore, the efficacy of ventilation utilities was evaluated. METHODS: Ventilation was assessed with the Oxylator ventilator, as well as the consecutive self-contained underwater breathing apparatus (SCUBA) regulators using an anaesthetic test lung: Poseidon Cyklon 5000, Poseidon XStream, Apeks TX 100, Spiro Arctic, Scubapro Air2 and Buddy AutoAir. RESULTS: Oxylator, Apeks TX 100, Arctic and Buddy AutoAir delivered reliable peak pressures and tidal volumes. In contrast, the ventilation parameters remarkably depended on duration and depth of pressing the purge button in Poseidon Cyklon 5000, Poseidon XStream and Scubapro Air2. Critical peak pressures occurred during ventilation with all these three regulators. DISCUSSION: The use of Poseidon Cyklon 5000, Poseidon XStream and Scubapro Air2 regulators is consequently not recommended for in-water ventilation. With the limitation that the devices were tested with a test lung and not in a human field study, Apeks TX 100, Spiro Arctic and Buddy AutoAir might be used for emergency ventilation and probably ease in-water resuscitation for the dive buddy of the victim. Professional rescue divers could be equipped with the Oxylator and an oxygen tank to achieve an early onset of efficient in-water ventilation in drowning victims.

Medical management of youth baseball and softball tournaments.

The medical management of youth baseball and softball tournaments requires both proper planning and a basic awareness of commonly seen sport-specific injuries. While youth sporting events are designed to be a fun experience for all, injuries and emergencies will occur. With proper planning, and supplies, the impact of these issues can be minimized. This article will outline some basic principles for the medical personnel that may be involved in youth baseball and softball events.

Medical coverage of youth basketball events.

Basketball is among the most popular team sports for boys and girls in the United States and is continuing to grow in popularity worldwide. Increased popularity translates to an increased number of events and, unfortunately, the injuries that occur as a result. In this article, we discuss ways to be prepared in the coverage of youth basketball events, with an emphasis on the evaluation and treatment of some of the most commonly encountered injuries within the sport of basketball. We also give special consideration to injuries that are specific to the skeletally immature athlete. By having a greater knowledge and understanding of these injuries, a provider of medical coverage for basketball events hopefully will gain a higher sense of confidence in handling associated problems as they arise.

Sideline coverage of youth football.

Youth football is a popular sport in the United States and has been for some time. There are currently more than 3 million participants in youth football leagues according to USA Football. While the number of participants and overall injuries may be higher in other sports, football has a higher rate of injuries. Most youth sporting events do not have medical personnel on the sidelines in event of an injury or emergency. Therefore it is necessary for youth sports coaches to undergo basic medical training in order to effectively act in these situations. In addition, an argument could be made that appropriate medical personnel should be on the sideline for collision sports at all levels, from youth to professional. This article will discuss issues pertinent to sideline coverage of youth football, including coaching education, sideline personnel, emergency action plans, age and size divisions, tackle versus flag football, and injury prevention.

Time to first compression using Medical Priority Dispatch System compression-first dispatcher-assisted cardiopulmonary resuscitation protocols.

INTRODUCTION: Without bystander cardiopulmonary resuscitation (CPR), cardiac arrest survival decreases 7%-10% for every minute of delay until defibrillation. Dispatcher-assisted CPR (D-CPR) has been shown to increase the rates of bystander CPR and cardiac arrest survival. Other reports suggest that the most critical component of bystander CPR is chest compressions with minimal interruption. Beginning with version 11.2 of the Medical Priority Dispatch System (MPDS) protocols, instructions for mouth-to-mouth ventilation (MTMV) and pulse check were removed and a compression-first pathway was introduced to facilitate rapid delivery of compressions. Additionally, unconscious choking and third-trimester pregnancy decision-making criteria were added in versions 11.3 and 12.0, respectively. However, the effects of these changes on time to first compression (TTFC) have not been evaluated. OBJECTIVE: We sought to quantify the TTFC of MPDS versions 11.2, 11.3, and 12.0 for all calls identified as cardiac arrest on call intake that did not require MTMV instruction. METHODS: Audio recordings of all D-CPR events for October 2005 through May 2010 were analyzed for TTFC. Differences in TTFC across versions were compared using the Kruskal-Wallis test. RESULTS: A total of 778 cases received D-CPR. Of these, 259 were excluded because they met criteria for MTMV (pediatric patients, allergic reaction, etc.), were missing data, or were not initially identified as cardiac arrest. Of the remaining 519 calls, the mean TTFC was 240 seconds, with no significant variation across the MPDS versions (p = 0.08). CONCLUSIONS: Following the removal of instructions for pulse check and MTMV, as well as other minor changes in the MPDS protocols, we found the overall TTFC to be 240 seconds with little variation across the three versions evaluated. This represents an improvement in TTFC compared with reports of an earlier version of MPDS that included pulse checks and MTMV instructions (315 seconds). However, the MPDS TTFC does not compare favorably with reports of older, non-MPDS protocols that included pulse checks and MTMV. Efforts should continue to focus on improving this key, and modifiable, determinant of cardiac arrest survival.

Is sports safety policy being translated into practice: what can be learnt from the Australian rugby union Mayday procedure?

AIM: To investigate the level of translation of the Australian Rugby Union 'Mayday' safety procedure into practice among community rugby union coaches in New South Wales (Australia). METHODS: All registered coaches of senior community rugby union teams in five zones/associations in the north-eastern region of the state were invited to complete a short online questionnaire at the end of the 2010 rugby season. The questionnaire was designed around the five RE-AIM dimensions and assessed: Reach, perceived Effectiveness, Adoption, Implementation and Maintenance of the Mayday procedure. RESULTS: Seventy (39%) coaches participated. There was a high level of awareness of the Mayday procedure, and most coaches believed it was effective in preventing injuries. The majority reported training their players in the procedure, although training was generally infrequent. Coaches were confident that their own players could implement the procedure appropriately if required to do so, but less confident that other teams or referees could do so. Barriers to providing training included not enough players at training, players not taking training seriously and technical difficulties (eg, verbalisation of instructions for physical tasks). CONCLUSION: The findings suggest that the translation of the Mayday 'policy' could be improved by building individual coach, and club or zone organisational capacity by ensuring that coaches have the resources and skills in 'how' to train their players to complement their existing knowledge on 'what' to train them; setting expectations that encourage coaches to provide regular training for players; and regular monitoring of player competency to perform the procedure appropriately.

Emergency cardiac care in the athletic setting: from schools to the Olympics.

Medical providers at sporting events must be well-trained in the care of cardiac emergencies. Optimal outcomes are most likely achieved through comprehensive emergency planning that ensures prompt and appropriate care. The diversity of athletic venues, as well as the age and competition level of different athlete populations, present challenges to the provision of appropriate emergency care in sport. An efficient and coordinated medical response to cardiac emergencies requires an established emergency action plan, training of potential first responders in cardiopulmonary resuscitation and use of an automated external defibrillator, coordinating communication and transportation systems, and ensuring access to appropriate medical equipment and supplies. Prompt recognition and early defibrillation are critical in the management of athletes suffering sudden cardiac arrest. This article reviews emergency planning and cardiac care in athletics, with special considerations presented for the school, large arena, mass event and Olympic settings.

A strontium-90 sequestrant for first-aid treatment of radiation emergency.

In this study, hydrophilic porous polymer beads with phosphonic acid groups (PGMA-EGDMA-TTA-MP) were synthesized, and assessed as a radioactive strontium-90 sequestrant for the treatment of the radiation emergency. Strontium ions were rapidly absorbed into the blood from the gastrointestinal (GI) tract after oral administration to rats, and distributed to the target organ, i.e., bones. Over 40% of the administered strontium was absorbed into the blood, while the remainder was discharged in the feces within 48 h after the administration. When the PGMA-EGDMA-TTA-MP beads were administered to rats subsequent to the strontium solution, the strontium had accumulated less in the femur. Consequently, the oral administration of the PGMA-EGDMA-TTA-MP beads was effective in suppressing the absorption of strontium from the GI tract.

A method for the removal of tungsten carbide rings.

BACKGROUND: The removal of metal rings from fingers is a well-described process that often employs a toothed cutting wheel or bolt cutters to sever the ring and allow it to be pried open. However, tungsten carbide (TC) rings are impervious to these traditional ring-cutting devices. STUDY OBJECTIVES: We sought to describe a method for removal of TC rings from cadaveric fingers and characterize potential complications of the technique. METHODS: On cadaveric fingers, we placed TC rings and created a snug fit by injecting a fluorescein and saline solution. The rings were removed by a controlled crushing technique using a pair of locking pliers. Fingers were inspected under magnification and using an LED (light-emitting diode) black light, and X-ray studies of each finger were obtained. Injuries were characterized. RESULTS: Six rings were applied and successfully removed from six cadaveric fingers through controlled ring shatter. After ring removal, two fingers demonstrated superficial (<1 mm deep) lacerations, one of which had residual debris within the wound. No phalangeal fractures were identified. CONCLUSION: Removal of a TC ring can be performed through controlled crushing using locking pliers. Superficial lacerations and retained debris are potential complications.

[Application of biologically active suture materials in emergency surgery of abdominal cavity organs].

An investigation of specific course of the wound process and near results of operations on 398 patients with emergency abdominal surgical pathology has revealed advantages of using new biologically active suture materials "Nikant" (with doxicyclin) and "Nikant-P" (with doxicyclin and stimulator of regeneration from the group of hermanium-containing organic compounds) in performing surgical interventions. Total number of patients with complications at the early postoperative period, operated using threads "Nikant" (38-29.9%) and "Nikant-P" (30-23.8%) proved to be reliably less than in patients of the control group (71-48.9%). The results of operations improved at the expense of considerable reduction of the number of postoperative local pyo-inflammatory processes.
