    Neonates and infants with brachial plexus injuries are typically treated using splinting, range-of-motion exercise, and, in more severe cases, nerve reconstruction. However, myofascial release--a common osteopathic manipulative treatment technique that has been used to manage thoracic outlet syndrome in adults--may provide effective, noninvasive management of brachial plexus injuries in neonates and infants. While emphasizing the importance of good communication with parents of affected patients, the authors review brachial plexus anatomy, describe diagnostic examinations, and outline a comprehensive treatment strategy.

    The aim of this study was to describe the mechanisms involved in stretch injuries of the brachial plexus. One hundred and fifty consecutive patients with supraclavicular brachial plexus injuries (BPI) were asked about the mechanism of injury during the actual injury event, particularly about the type of trauma to their shoulder, shoulder girdle and head. Fifty-seven of the patients provided enough information about their accident to allow for analysis of the shoulder trauma. The injury mechanism for all patients having upper root or total palsy (n=46) was described as a direct vertical impact to the shoulder. In 44 of these patients, the trauma followed a motorcycle accident and, in most of them, the patient hit a fixed vertical structure before falling to the ground. The injury mechanism for the lower root palsy cases (n=11) was variable. The most frequent mechanism was forceful anterior shoulder compression by a car seat belt. We found that injury mechanisms differed significantly from the ones commonly discussed in published studies. PMID:27117025

    Objectives Traumatic brachial plexus injury causes severe functional impairment of the arm. Elbow flexion is often affected. Nerve surgery or tendon transfers provide the only means to obtain improved elbow flexion. Unfortunately, the functionality of the arm often remains insufficient. Stem cell therapy could potentially improve muscle strength and avoid muscle-tendon transfer. This pilot study assesses the safety and regenerative potential of autologous bone marrow-derived mononuclear cell injection in partially denervated biceps. Methods Nine brachial plexus patients with insufficient elbow flexion (i.e., partial denervation) received intramuscular escalating doses of autologous bone marrow-derived mononuclear cells, combined with tendon transfers. Effect parameters included biceps biopsies, motor unit analysis on needle electromyography and computerised muscle tomography, before and after cell therapy. Results No adverse effects in vital signs, bone marrow aspiration sites, injection sites, or surgical wound were seen. After cell therapy there was a 52% decrease in muscle fibrosis (p = 0.01), an 80% increase in myofibre diameter (p = 0.007), a 50% increase in satellite cells (p = 0.045) and an 83% increase in capillary-to-myofibre ratio (p < 0.001) was shown. CT analysis demonstrated a 48% decrease in mean muscle density (p = 0.009). Motor unit analysis showed a mean increase of 36% in motor unit amplitude (p = 0.045), 22% increase in duration (p = 0.005) and 29% increase in number of phases (p = 0.002). Conclusions Mononuclear cell injection in partly denervated muscle of brachial plexus patients is safe. The results suggest enhanced muscle reinnervation and regeneration.

    Objective: To evaluate the results from transposition of the triceps for elbow flexion in patients with chronic and complete injury to the upper trunk of the brachial plexus. Methods: This was a retrospective study, including only patients who had biceps grade 0 and triceps grade 5, who underwent anterior transfer of the triceps muscle, performed between 1998 and 2005. The affected side, sex, type of accident, strength of elbow flexion, complications and patient satisfaction were investigated in 11 cases. Results: 10 patients were male; the age range was from 24 to 49 years, with a mean of 33.7 years. The minimum time between injury and surgery was 21 months (range 21-74 months). The left side was affected in eight cases, and the right only in three. Good results were obtained in 10 patients, who acquired elbow flexion strength of grade 3 (two cases) and grade 4 (eight cases), while one evolved unfavorably with grade 2 strength. Two cases had complications (initial compartment syndrome and insufficient tensioning). All the patients said that they were satisfied with the procedure. Conclusion: Anterior transposition of the triceps muscle provided patient satisfaction in all cases except one, attaining strength grade 4 in eight cases, grade 3 in two cases and grade 2 in one case.

    This study aims at the effects of traumatic brachial plexus lesion with root avulsions (BPA) upon the organization of the primary motor cortex (M1). Nine right-handed patients with a right BPA in whom an intercostal to musculocutaneous (ICN-MC) nerve transfer was performed had post-operative resting state fMRI scanning. The analysis of empirical functional correlations between neighboring voxels revealed faster correlation decay as a function of distance in the M1 region corresponding to the arm in BPA patients as compared to the control group. No differences between the two groups were found in the face area. We also investigated whether such larger decay in patients could be attributed to a gray matter diminution in M1. Structural imaging analysis showed no difference in gray matter density between groups. Our findings suggest that the faster decay in neighboring functional correlations without significant gray matter diminution in BPA patients could be related to a reduced activity in intrinsic horizontal connections in M1 responsible for upper limb motor synergies.

    Brachial plexus injury represents the most severe nerve injury of the extremities. While obstetric brachial plexus injury has showed a reduction in the number of cases due to the improvements in obstetric care, brachial plexus injury in the adult is an increasingly common clinical problem. The therapeutic measures depend on the pathologic condition and the location of the injury: Preganglionic avulsions are usually not amenable to surgical repair; function of some denervated muscles can be restored with nerve transfers from intercostals or accessory nerves and contralateral C7 transfer. Postganglionic avulsions are repaired with excision of the damaged segment and nerve autograft between nerve ends or followed up conservatively. Magnetic resonance imaging is the modality of choice for depicting the anatomy and pathology of the brachial plexus: It demonstrates the location of the nerve damage (crucial for optimal treatment planning), depicts the nerve continuity (with or without neuroma formation), or may show a completely disrupted/avulsed nerve, thereby aiding in nerve-injury grading for preoperative planning. Computed tomography myelography has the advantage of a higher spatial resolution in demonstration of nerve roots compared with MR myelography; however, it is invasive and shows some difficulties in the depiction of some pseudomeningoceles with little or no communication with the dural sac.

    2013-01-01

    Background Symptoms of obstetric brachial plexus injury (OBPI) vary widely over the course of time and from individual to individual and can include various degrees of denervation, muscle weakness, contractures, bone deformities and functional limitations. To date, no universally accepted overall framework is available to assess the outcome of patients with OBPI. The objective of this paper is to outline the proposed process for the development of International Classification of Functioning, Disability and Health (ICF) Core Sets for patients with an OBPI. Methods The first step is to conduct four preparatory studies to identify ICF categories important for OBPI: a) a systematic literature review to identify outcome measures, b) a qualitative study using focus groups, c) an expert survey and d) a cross-sectional, multicentre study. A first version of ICF Core Sets will be defined at a consensus conference, which will integrate the evidence from the preparatory studies. In a second step, field-testing among patients will validate this first version of Core Sets for OBPI. Discussion The proposed method to develop ICF Core Sets for OBPI yields a practical tool for multiple purposes: for clinicians to systematically assess and evaluate the individual’s functioning, for researchers to design and compare studies, and for patients to get more insight into their health problems and their management.

    Combined neurotization of both axillary and suprascapular nerves in shoulder reanimation has been widely accepted in brachial plexus injuries, and the functional outcome is much superior to single nerve transfer. This study describes the surgical anatomy for axillary nerve relative to the available donor nerves and emphasize the salient technical aspects of anterior deltopectoral approach in brachial plexus injuries. Fifteen patients with brachial plexus injury who had axillary nerve neurotizations were evaluated. Five patients had complete avulsion, 9 patients had C5, six patients had brachial plexus injury pattern, and one patient had combined axillary and suprascapular nerve injury. The long head of triceps branch was the donor in C5,6 injuries; nerve to brachialis in combined nerve injury and intercostals for C5-T1 avulsion injuries. All these donors were identified through the anterior approach, and the nerve transfer was done. The recovery of deltoid was found excellent (M5) in C5,6 brachial plexus injuries with an average of 134.4° abduction at follow up of average 34.6 months. The shoulder recovery was good with 130° abduction in a case of combined axillary and suprascapular nerve injury. The deltoid recovery was good (M3) in C5-T1 avulsion injuries patients with an average of 64° shoulder abduction at follow up of 35 months. We believe that anterior approach is simple and easy for all axillary nerve transfers in brachial plexus injuries. PMID:22434572

    We discuss the case of an independent 80-year-old Caucasian woman, being treated with new oral anticoagulants for a previous deep vein thrombosis, who had fallen on her right shoulder. She made a delayed presentation to the emergency department with a wrist drop in her right dominant hand. She had right arm bruising with good distal pulses but had a global neurological deficit in the hand. Plain radiographs of the shoulder, humerus, elbow, forearm and wrist demonstrated no fractures. MRI showed a significant right axillary lesion distorting the surrounding soft tissues, including the brachial plexus, and CT with contrast confirmed this to be a large axillary pseudoaneurysm. This was treated with an endovascular stent resulting in slightly improved motor function, but the significant residual deficit required subsequent rehabilitation to improve right upper limb function.

    Brachial plexus injury in a patient under general anesthesia (GA) is not uncommon, despite careful positioning and, particularly, awareness of the possibility. The mechanism of injury is stretching and compression of the brachial plexus over a prolonged period. Positioning the patient within the computed tomography (CT) gantry for abdominal or chest procedures can simulate a surgical procedure, particularly when GA is used. The potential for brachial plexus injury is increased if the case is prolonged and the patient's arms are raised above the head to avoid CT image degradation from streak artifacts. We report a case of profound brachial plexus palsy following a CT-guided radiofrequency ablation procedure under GA. Fortunately, the patient recovered completely. We emphasize the mechanism of injury and detail measures to combat this problem, such that radiologists are aware of this potentially serious complication.

    Our previous studies have demonstrated that some male patients suffering from brachial plexus injury, particularly brachial plexus root avulsion, show erectile dysfunction to varying degrees. However, the underlying mechanism remains poorly understood. In this study, we evaluated the erectile function after establishing brachial plexus root avulsion models with or without spinal cord injury in rats. After these models were established, we administered apomorphine (via a subcutaneous injection in the neck) to observe changes in erectile function. Rats subjected to simple brachial plexus root avulsion or those subjected to brachial plexus root avulsion combined with spinal cord injury had significantly fewer erections than those subjected to the sham operation. Expression of neuronal nitric oxide synthase did not change in brachial plexus root avulsion rats. However, neuronal nitric oxide synthase expression was significantly decreased in brachial plexus root avulsion + spinal cord injury rats. These findings suggest that a decrease in neuronal nitric oxide synthase expression in the penis may play a role in erectile dysfunction caused by the combination of brachial plexus root avulsion and spinal cord injury.

    We present the case of a 32-year-old female who sustained a left acromioclavicular (AC) joint type V injury and brachial plexus injury. The patient's AC joint injury was identified 6 days after she was involved in a motorbike accident where she sustained multiple other injuries. She required operative fixation of the AC joint using a locking compression medial proximal tibial plate. At 3 months post operatively, the patient was found to have a subluxed left shoulder as a result of an axonal injury to the upper trunk of the brachial plexus. In addition, the tibial plate had cut out. The plate was subsequently removed. At 8 months the glenohumeral articulation had been restored and the patient had clinically regained significant shoulder function. After 15 months the patient was pain free and could complete all her activities of daily living without impediment. She returned to playing competitive pool after 24 months. PMID:24855076

    Traumatic pseudoaneurysm of the axillary artery combined with brachial plexus injury is extremely rare. The factors that influence the symptoms and functional recovery related to this condition are unclear. Nine patients who had sustained this trauma were surgically treated at our unit between June 1999 and November 2010. The cause of trauma, symptoms, signs and examinations of neurological and vascular deficits, and the surgical findings of the involved nerves and vessels were recorded in detail. The functional recovery of vessels and nerves, as well as the extent of pain, were evaluated, respectively. The average length of patient follow-up was 4.5 years (range, 24 months to 11.3 years). After vessel repair, whether by endovascular or operative treatment, the distending, constant, and pulsating pain was relieved in all patients. Furthermore, examination of the radial artery pulse on the repaired side appeared normal at last follow-up. All patients showed satisfactory sensory recovery, with motor recovery rated as good in five patients and fair in four patients. The symptom characteristics varied with the location of the damage to the axillary artery. Ultrasound examination and computed tomography angiography are useful to evaluate vascular injury and provide valuable information for operative planning. Surgical exploration is an effective therapy with results related to the nerve injury condition of the brachial plexus. PMID:25412426

    Brachial plexus trauma (BPT) often affects young patients and may result in lasting functional deficits. Standard care following BPT involves monitoring for clinical and electrophysiological evidence of muscle reinnervation, with surgical treatment decisions based on the presence or absence of spontaneous recovery. Data are emerging to suggest that central and peripheral adaptation may play a role in recovery following BPT. The present review highlights adaptive and maladaptive mechanisms of central and peripheral nervous system changes following BPT that may contribute to functional outcomes. Rehabilitation and other treatment strategies that harness or modulate these intrinsic adaptive mechanisms may improve functional outcomes following BPT. PMID:26409073

    Obstetric brachial plexus injuries are common, with an incidence of 0.42 per 1000 live births in the UK, and with 25% of patients being left with permanent disability without intervention. The shoulder is the most commonly affected joint and, as a result of the subsequent imbalance of musculature, the abnormal deforming forces cause dysplasia of the glenohumeral joint. In the growing child, this presents with changing pattern of pathology, which requires a multidisciplinary approach and a broad range of treatment modalities to optimize function.

    There is limited qualitative research available that explores the impact of a traumatic brachial plexus injury on patients and their quality of life experiences. This paper builds upon previous work on this subject by this author. Patients were selected from those who were on the database for the Scottish National Brachial Plexus Injury Service between 2011 and 2013. The World Health Organization (WHO) Quality of Life (QoL) - BREF questionnaire was used and 47 questionnaires were distributed with 22 returned. Findings included patients' ratings of their quality of life, physical and psychological health along with their perceived satisfaction with social relationships. PMID:27091305

    Traumatic brachial plexus root avulsions are devastating injuries, and are complex and challenging to reconstruct. Double free muscle transfer using the gracilis muscles is a potentially effective method of restoring upper extremity function. The authors report on the first two patients treated using this technique in Canada. Both sustained traumatic brachial plexus root avulsion injuries resulting in a flail arm. In the first step of this two-stage procedure, a gracilis muscle was transferred to restore elbow flexion, and wrist and digit extension. Months later, the transfer of the second gracilis muscle was performed to enhance elbow flexion and to enable wrist and digit flexion. Postoperatively, both patients achieved Medical Research Council grade 4 elbow flexion, functional handgrip and were able to return to gainful employment. Patient satisfaction was high and active range of motion improved substantially. The authors’ experience supports the use of this technique following severe brachial plexus injury. PMID:25152644

    2007-01-01

    Background Despite considerable analysis and preventive strategies, brachial plexus injuries remain fairly common in the perioperative setting. These injuries range from brief periods of numbness or discomfort in the immediate postoperative period to, in rare cases, profound, prolonged losses of sensation and function. We present a case of an orthopedic surgery patient who suffered a brachial plexus injury while under anesthesia after trying to sit upright with his arms restrained. Case presentation After the uneventful placement of an intramedullary tibial nail, an 18 year old patient tried to sit upright with his arms restrained while still under the influence of anesthesia. In the immediate postoperative period, the patient complained of a profound loss of sensation in his left arm and an inability to flex his left elbow, suppinate his arm, or abduct and rotate his shoulder. Neurological examination and subsequent studies revealed a C5-6 brachial plexus injury. The patient underwent range of motion physical therapy and, over the next three months, regained the full function and sensation of his left arm. Conclusion Restraining arms during general anesthesia to prevent injury remains a wise practice. However, to avoid injuring the brachial plexus while the arms are restrained, extra caution must be used to prevent unexpected patient movement and to ensure gentle emergence. PMID:18271944

    The purpose of this study was to evaluate the role of upright magnetic resonance imaging (MRI) shoulder scanning in the diagnosis of glenohumeral deformity following obstetric brachial plexus injury (OBPI). Eighty-nine children (ages 0.4 to 17.9 years) with OBPI who have medial rotation contracture and reduced passive and active lateral rotation of the shoulder were evaluated via upright MRI of the affected glenohumeral joint. Qualitative impressions of glenoid form were recorded, and quantitative measurements were made of glenoid version and posterior subluxation. Glenoid version of the affected shoulder averaged -16.8 +/- 11.0 degrees (range, -55 degrees to 1 degrees ), and percentage of the humeral head anterior to the glenoid fossa (PHHA) averaged 32.6 +/- 16.5% (range, -17.8% to 52.4%). The glenoid form was normal in 43 children, convex in 19 children and biconcave in 27 children. Standard MRI protocols were used to obtain bilateral images from 14 of these patients. Among the patients with bilateral MR images, glenoid version and PHHA were significantly different between the involved and uninvolved shoulders (P<.000). Glenoid version in the involved shoulder averaged -19.0 +/- 13.1 degrees (range, -52 degrees to -3 degrees ), and PHHA averaged 29.7 +/- 18.4% (range, -16.2% to 48.7%). In the uninvolved shoulder, the average glenoid version and PHHA were -5.2 +/- 3.7 degrees (range, -12 degrees to -1 degrees ) and 47.7 +/- 3.0% (range, 43% to 54%), respectively. The relative beneficial aspects of upright MRI include lack of need for sedation, low claustrophobic potential and, most important, natural, gravity-influenced position, enabling the surgeon to visualize the true preoperative picture of the shoulder. It is an effective tool for demonstrating glenohumeral abnormalities resulting from brachial plexus injury worthy of surgical exploration. PMID:17448618

    2013-03-01

    Paediatric clavicle fractures are common injuries presenting to orthopaedic surgeons. The majority of these represent midshaft low energy fractures, which in the vast majority of cases are treated non-operatively and recover rapidly. The main indications to consider operative intervention include high energy of injury, >2 cm shortening, open fractures and associated vascular or neurological injuries. Brachial plexus (BP) injuries are uncommon with variable outcomes. They often result from high energy motorcycle related accidents with potentially fatal associated injuries such as vascular disruption. Their management is complex, requiring expertise, and they are therefore usually managed in supraregional centres. We present a unique case of a low energy midshaft clavicle fracture in a paediatric patient in whom there was an acute BP injury and subclavian artery compression that has not been described previously.

    A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was ‘does retraction of the sternum during median sternotomy result in brachial plexus injuries or peripheral neuropathies?’ Altogether 58 papers were found using the reported search, of which 12 represented the best evidence to answer the question. The authors, date, journal and country of publication, patient group studied, study type, relevant outcomes and results of these papers were tabulated. Caudal placement of the retractor or relieving the pressure superiorly by removing the upper blades of a retractor (P = 0.02) and use of a caudally placed symmetrical retractor has been shown to reduce neuropathy. Positioning of the patient with ‘hands up’ positioning showed significant reduction in the incidence of brachial plexus injuries. Furthermore, how wide the retractor is opened and use of an asymmetrical retractor for internal mammary artery (IMA) harvesting are also important factors in quantifying risk of postoperative neuropathy. Wider sternal retraction and longer bypass time did increase the risk of developing postoperative neuropathy. Three asymmetrical retractors were looked at that demonstrates the Delacroix–Chevalier to be the safest (P < 0.05). We conclude that median sternotomy risks brachial plexus injury and where possible the sternum should be opened as small a distance as possible with symmetrical retractor and using a caudally placed retractor.

    Purpose To determine the impact on families of children with brachial plexus injuries in order to best meet their clinical and social needs. Methods Our cross-sectional study included families with children between the ages of 1 and 18 with birth or non-neonatal brachial plexus injuries (BPI). The consenting parent or guardian completed a demographic questionnaire and the validated Impact on Family Scale during a single assessment. Total scores can range from 0-100, with the higher the score indicating a higher impact on the family. Factor analysis and item-total correlations were used to examine structure, individual items, and dimensions of family impact. Results One hundred two caregivers participated. Overall, families perceived various dimensions of impact on having a child with a BPI. Total family impact was 43. The 2 individual items correlating most strongly with the overall total score were from the financial dimension of the Impact on Family Scale. The strongest demographic relationship was traveling nationally for care and treatment of the BPI. Severity of injury was marginally correlated with impact on the family. Parent-child agreement about the severity of the illness was relatively high. Conclusion Caretakers of children with a BPI perceived impact on their families in the form of personal strain, family/social factors, financial stress, and mastery. A multidisciplinary clinical care team should address the various realms of impact on family throughout the course of treatment. Level of Evidence II Prognostic PMID:25936738

    2009-10-01

    We used end-to-side nerve coaptation combined with standard end-to-end neurotisations to treat 11 patients who presented with complete (six cases) or incomplete (five cases) traumatic brachial plexus injuries. All patients were available for functional evaluation at a minimum of 2 years postoperatively. In three patients with shoulder abduction recovery, electromyographical studies (EMG) showed a contribution from the end-to-side neurotisation. In the remaining cases end-to-side neurotisations were unsuccessful. Our study did not demonstrate a reliable role for end-to-side nerve suture in brachial plexus surgery. We believe that at present end-to-side suture must not be a substitute for standard reconstructive techniques in brachial plexus surgery. Occasionally termino-lateral nerve sutures may represent a support to standard reconstructive procedures especially in case of severe injuries when few undamaged donor nerves are available.

    A brachial plexus injury model was established in rabbits by stretching the C6 nerve root. Immediately after the stretching, a suspension of human amniotic epithelial cells was injected into the injured brachial plexus. The results of tensile mechanical testing of the brachial plexus showed that the tensile elastic limit strain, elastic limit stress, maximum stress, and maximum strain of the injured brachial plexuses were significantly increased at 24 weeks after the injection. The treatment clearly improved the pathological morphology of the injured brachial plexus nerve, as seen by hematoxylin eosin staining, and the functions of the rabbit forepaw were restored. These data indicate that the injection of human amniotic epithelial cells contributed to the repair of brachial plexus injury, and that this technique may transform into current clinical treatment strategies.

    Obstetric brachial plexus palsy is a devastating birth injury. While many children recover spontaneously, 20-25% are left with a permanent impairment of the affected limb. So far, concepts of pathology and recovery have focused on the injury of the peripheral nerve. Proximal nerve injury at birth, however, leads to massive injury-induced…

    Brachial plexus injury is an unusual and under-recognised complication of coronary artery bypass grafting especially when internal mammary artery harvesting takes place. It is believed to be due to sternal retraction resulting in compression of the brachial plexus. Although the majority of cases are transient, there are cases where the injury is permanent and may have severe implications as illustrated in the accompanying case history. PMID:12612322

    The purpose of this study was to investigate the effectiveness of shoulder function restoration by dual nerve transfers, spinal accessory nerve to the suprascapular nerve and 2 intercostal nerves to the anterior branch of the axillary nerve, in patients with shoulder paralysis that resulted from brachial plexus avulsion injury. It was a retrospective analysis to assess the impact of a variety of factors on reanimation of shoulder functions with dual nerve transfers. A total of 19 patients were included in this study. Most of these patients sustained avulsions of C5, C6, and C7 nerve roots (16 patients). Three of them had avulsions of C5 and C6 roots only. Through a posterior approach, direct coaptation of the intercostal nerves and the anterior branch of the axillary nerve was performed, along with accessory nerve transfer to the suprascapular nerve. Satisfactory shoulder function recovery (93.83° of shoulder abduction and 54.00° of external rotation on average) was achieved after a 62-month follow-up. This dual nerve transfer procedure provided us with a reliable and effective method for shoulder function reconstruction after brachial plexus root avulsion, especially C5/C6/C7 avulsion. The level of evidence is therapeutic IV. PMID:26835823

    This study compares the hands-up (HU) with the arms at side (AAS) position to determine whether one is beneficial in reducing brachial plexus stress during asymmetric sternal retraction. Eighty patients undergoing cardiac surgery were assigned to either Group 1 (AAS) or Group 2 (HU). Perioperative neurologic evaluations of the brachial plexus were performed and somatosensory evoked potentials (SSEPs) were collected during internal mammary artery harvest using asymmetric sternal retraction. Demographic data, SSEP changes, and postoperative brachial plexus symptoms were compared between groups. SSEP amplitude decreased in 95% of all patients during retractor placement with substantial decreases (> 50%) observed on the left side in 50% of the AAS and 35% of the HU patients. Amplitude recovery was normally seen in both groups after asymmetric retractor removal. Similar changes were noted, to a lesser degree, on the right side. During asymmetric sternal retraction, HU positioning offered minimal benefit in reducing brachial plexus stress as measured by SSEP. Three of the seven AAS patients who reported brachial plexus symptoms had an ulnar nerve distribution of injury. However, none of the four patients with plexus symptoms in the HU group had ulnar nerve problems, suggesting that the higher incidence of postoperative symptoms observed with AAS positioning may occur from ulnar nerve compression.

    Objective: We evaluated the "extended" long-term (5 years) functional outcomes in obstetric brachial plexus injury (OBPI) patients, who underwent triangle tilt surgery between February 2005 and January 2008. Methods: Twenty two children (9 girls and 13 boys, mean age at surgery was 5.8 years; ranging 2.1-11.8 years old), who initially presented with medial rotation contracture and scapula deformity secondary to obstetric brachial plexus injury were included in this study. Functional movements were evaluated pre-operatively, and 5 years following triangle tilt surgery by modified Mallet scale. Results: Here, we report long-term (5 years) follow-up of triangle tilt surgery for 22 OBPI patients. Upper extremity functional movements such as, external rotation (2.5±0.6 to 4.1±0.8, p<0.0001), hand-to-spine (2.6±0.6 to 3.4±1.1, p<0.005), hand-to-neck (2.7±0.7 to 4.3±0.7, p<0.0001), hand-to-mouth (2.3±0.9 (92º±33) to 4.2±0.5 (21º±16), p<0.0001), and supination (2.6±1.1 (-8.2º ±51) to 4.1±0.7 (61±32)) were significantly improved (p<0.0001), and maintained over the extended long-term (5 years). Total modified Mallet functional score was also shown to improve from 14.1±2.7 to 20.3±2.5. Conclusions: The triangle tilt surgery improved all shoulder functions significantly, and maintained over the extended long-term (5 years) in these patients. PMID:23730369

    1994-08-01

    Brachial plexus injury after coronary artery bypass grafting (CABG) continues to be a common problem postoperatively. With the use of somatosensory evoked potential monitoring (SSEP), neurologic integrity of the brachial plexus during internal mammary artery (IMA) harvest was assessed and the Rultract and Pittman sternal retractors were compared to determine what effect they had on SSEP characteristics. Results showed that the Rultract and Pittman retractors caused large decreases in SSEP amplitudes after insertion, (1.25 +/- 0.14 versus 0.72 +/- 0.09, P < 0.05; and 1.64 +/- 0.27 versus 0.91 +/- 0.14, P < 0.05) respectively. This decrease was noted in 85% of Rultract and 68.75% of Pittman patients, respectively. Amplitudes increased after retractor removal but never returned to baseline values. Cooley retractor placement in the patients not undergoing IMA harvest (control) produced only mild decreases in amplitude. Waveform latency increased in all groups after retractor placement, but these increases were thought to be clinically insignificant. Postoperatively, three patients in each of the IMA retractor groups had brachial plexus symptoms (18%), whereas only one patient in the control group had symptoms. Somatosensory evoked potential monitoring seems to be a sensitive intraoperative monitor for assessing brachial plexus injury during CABG. The nerve plexus seems to be most at risk for pathologic injury during retraction of the sternum for IMA harvest. Though the Rultract retractor caused greater changes in SSEP characteristics than the Pittman, no clinical outcome differences between the two could be ascertained. Using SSEP monitoring may reduce brachial plexus injury during IMA harvest by allowing early detection of nerve compromise and therapeutic interventions to alleviate the insult while under general anesthesia.

    Two red-tailed hawks (Buteo jamaicensis), found near Deltaville, Virginia (USA), were evaluated because of inability to use a wing. Results of needle electromyographic studies of the affected wing muscles in both hawks were compatible with denervation. On euthanasia, one hawk had extensive axon and myelin loss with multifocal perivascular lymphocytic inflammation of its brachial plexus and radial nerve. Demyelination and axon loss in the dorsal white matter of the spinal cord on the affected side also were found at the origin of the brachial plexus. The other hawk's wing had not returned to functional status > 2 yr after injury. PMID:8383253

    Objective: To investigate whether a sensorimotor deficit of the upper limb following a brachial plexus injury (BPI) affects the upright balance. Design: Eleven patients with a unilateral BPI and 11 healthy subjects were recruited. The balance assessment included the Berg Balance Scale (BBS), the number of feet touches on the ground while performing a 60 s single-leg stance and posturographic assessment (eyes open and feet placed hip-width apart during a single 60 s trial). The body weight distribution (BWD) between the legs was estimated from the center of pressure (COP) lateral position. The COP variability was quantified in the anterior-posterior and lateral directions. Results: BPI patients presented lower BBS scores (p = 0.048) and a higher frequency of feet touches during the single-leg stance (p = 0.042) compared with those of the healthy subjects. An asymmetric BWD toward the side opposite the affected arm was shown by 73% of BPI patients. Finally, higher COP variability was observed in BPI patients compared with healthy subjects for anterior-posterior (p = 0.020), but not for lateral direction (p = 0.818). Conclusions: This study demonstrates that upper limb sensorimotor deficits following BPI affect body balance, serving as a warning for the clinical community about the need to prevent and treat the secondary outcomes of this condition.

    Background and Aims: Supraclavicular approach to the brachial plexus may be associated with complications such as pneumothorax, inadvertent vascular puncture, inter-scalene block and neurovascular injuries. The present study was conceived to find out the variation in depth of brachial plexus to suggest the minimum length of needle required to effectively perform the block, thus preventing possible complications. Methods: After approval from our Institutional Ethical Committee, informed and written consent was obtained from each of the ninety American Society of Anesthesiologists Physical Status I and II patients recruited, of either sex in the age group of 20–50 years. Supraclavicular fossa was scanned using a high-frequency linear probe, and the distances (shortest distance [SD] from skin to the most superficial neural element and longest distance [LD] from skin to the most deep neural element) were measured using on-screen callipers on optimal frozen image. Pearson correlation was used to find out the relation between these two distances and demographic parameters. Results: Mean SD was 0.60 ± 0.262 cm, and mean LD was found to be 1.34 ± 0.385 cm. We observed significant correlation between these two distances with weight and body mass index (BMI). Conclusion: Significant correlation was observed between SD and LD with weight and BMI. We suggest that a needle with a shaft length of 3 cm will be sufficient to reach the sheath of the brachial plexus during performance of the block. PMID:27330200

    Complex regional pain syndrome secondary to brachial plexus injury is often severe, debilitating and difficult to manage. Percuteneous radiofrequency sympathectomy is a relatively new technique, which has shown promising results in various chronic pain disorders. We present four consecutive patients with complex regional pain syndrome secondary to brachial plexus injury for more than 6 months duration, who had undergone percutaneous T2 and T3 radiofrequency sympathectomy after a diagnostic block. All four patients experienced minimal pain relief with conservative treatment and stellate ganglion blockade. An acceptable 6 month pain relief was achieved in all 4 patients where pain score remained less than 50% than that of initial score and all oral analgesics were able to be tapered down. There were no complications attributed to this procedure were reported. From this case series, percutaneous T2 and T3 radiofrequency sympathectomy might play a significant role in multi-modal approach of CRPS management. PMID:24156009

    2015-10-01

    Brachial plexus injuries induce corresponding cortical representations to be occupied by adjacent cortices. The purpose of this study was to clarify if contralateral homologous motor regions of adjacent cortices influence occupation of deafferented motor cortex. 36 rats were divided into 3 groups of 12 each. In group 1, total brachial plexus root avulsion (tBPRA) was made on the left side. In group 2, rats underwent left tBPRA combined with corpus callosum transection (CCX). In group 3, only CCX was performed. 6 rats in each group were used for intracortical microstimulation (ICMS) to map representations of motor cortex in the right hemisphere at 7 days and the other 6 rats, at 3 months. 18 more rats without any operation underwent ICMS, with 6 each taken to serve as normal control for motor cortical representations' changes caused by different surgery. Results showed that in groups 1 and 2, sites for motor cortical representations of vibrissae, of neck and of the hindlimb was statistically more than that of control, respectively, and statistically more sites were found at 3 months than at 7 days, respectively. At the two time points, sites for vibrissa cortices and that for the hindlimb were statistically more in group 2 than in group 1, respectively. CCX alone did not induce change of site number for motor cortical representations. We conclude that after tBPRA, contralateral homologous motor cortices may, to some extent, prevent neighboring cortices from encroachment on motor cortical representations of the brachial plexus.

    2007-01-01

    Background The authors describe a new computerized tomography (CT) myelography technique with coronal and oblique coronal view to demonstrate the status of the cervical nerve rootlets involved in brachial plexus injury. They discuss the value of this technique for diagnosis of nerve root avulsion compared with CT myelography with axial view. Methods CT myelography was performed with penetration of the cervical subarachnoid space by the contrast medium. Then the coronal and oblique coronal reconstructions were created. The results of CT myelography were evaluated and classified with presence of pseudomeningocele, intradural ventral nerve rootlets, and intradural dorsal nerve rootlets. The diagnosis was by extraspinal surgical exploration with or without spinal evoked potential measurements and choline acetyl transferase activity measurement in 25 patients and recovery by a natural course in 3 patients. Its diagnostic accuracy was compared with that of CT myelography with axial view, correlated with surgical findings or a natural course in 57 cervical roots in 28 patients. Results Coronal and oblique coronal views were superior to axial views in visualization of the rootlets and orientation of the exact level of the root. Sensitivity and specificity for coronal and oblique coronal views of unrecognition of intradural ventral and dorsal nerve root shadow without pseudomeningocele in determining pre-ganglionic injury were 100% and 96%, respectively. There was no statistically significant difference between coronal and oblique coronal views and axial views. Conclusion The information by the coronal and oblique coronal slice CT myelography enabled the authors to assess the rootlets of the brachial plexus and provided valuable data for helping to decide whether to proceed with exploration, nerve repair, primary reconstruction.

Early assessment guides the initial plan of care and influences follow-up and long-term outcome. PURPOSE To review methods used to assess, classify and monitor the extent and influence of PBPI with an emphasis on guidelines for clinicians. METHODS We use The International Classification of Functioning, Disability, and Health (ICF) model to provide a guide to assessment after PBPI for rehabilitation clinicians. DISCUSSION With information gained from targeted assessments, clinicians can design interventions to increase the opportunities infants and children have for optimal recovery and to attain skills that allow participation in areas of interest.

    The purpose of this study was to observe whether the results of the median nerve fascicle transfer to the biceps are equivalent to the classical ulnar nerve fascicle transfer, in terms of elbow flexion strength and donor nerve morbidity. Twenty-five consecutive patients were operated between March 2007 and July 2013. The patients were divided into two groups. In Group 1 (n = 8), the patients received an ulnar nerve fascicle transfer to the biceps motor branch. In Group 2 (n = 15), the patients received a median nerve fascicle transfer to the biceps motor branch. Two patients with follow-up less than six months were excluded. Both groups were similar regarding age (P = 0.070), interval of injury (P = 0.185), and follow-up period (P = 0.477). Elbow flexion against gravity was achieved in 7 of 8 (87.5%) patients in Group 1, versus 14 of 15 (93.3%) patients in Group 2 (P = 1.000). The level of injury (C5-C6 or C5-C7) did not affect anti-gravity elbow flexion recovery in both the groups (P = 1.000). It was concluded that the median nerve fascicle transfer to the biceps is as good as the ulnar nerve fascicle transfer, even in C5-C7 injuries. PMID:24753064

    Objective: Treating brachial plexus injuries is a major challenge, especially lesions that are presented late, with more than 12 months of evolution. We retrospectively analyzed patients who underwent one of the possibilities for attempting to restore the function of upper limbs affected under such conditions: microsurgical transfer of the gracilis muscle for elbow flexion. Methods: Eight patients were included, divided into two groups: one in which the procedure consisted of neurorrhaphy of the muscle flap with sural nerve grafting and anastomosis more distally; and the other, in which the neurorrhaphy was performed directly on the spinal accessory nerve, with anastomosis in thoracoacromial vessels. Results: We found a significant difference between the groups. A greater number of satisfactory results (75% M4) were found among patients who underwent direct neurorrhaphy, whereas the procedure using grafts for neurorrhaphy was less successful (25% M4). Conclusion: Patients who underwent microsurgical functional transfer of the gracilis muscle in which vascular anastomoses were performed in thoracoacromial vessels presented better functional outcomes than shown by those whose anastomoses were in the brachial artery with subsequent use of a nerve graft.

    Objective This is a retrospective review of 22 surgically treated benign and malignant tumors of brachial plexus region to describe clinical presentation, the characteristics of brachial plexus tumor and clinical outcomes with a literature review. Methods Twenty-one patients with consecutive 22 surgeries for primary brachial plexus tumors were enrolled between February 2002 and November 2011 were included in this study. The medical records of all patients were reviewed. Results Eleven male and 10 female patients were enrolled. Mean age was 39 years. Three patients had brachial plexus tumor associated with neurofibromatosis (13.6%). Presenting signs and symptoms included parenthesis and numbness (54.5%), radiating pain (22.7%), direct tenderness and pain (27.2%), palpable mass (77.3%). Twelve patients presented preoperative sensory deficit (54.5%) and 9 patients presented preoperative motor deficit (40.9%). Twenty tumors (90.9%) were benign and 2 tumors (9.1%) were malignant. Benign tumors included 15 schwannomas (68.2%), 4 neurofibromas (18.2%) and 1 granular cell tumor (4.5%). There were 1 malignant peripheral nerve sheath tumor (MPNST) and 1 malignant granular cell tumor. Gross total resection was achieved in 16 patients (72.7%), including all schwannomas, 1 neurofibroma. Subtotal resection was performed in 6 tumors (27.3%), including 3 neurofibromatosis associated with brachial plexus neurofibromas, 1 MPNST and 2 granular cell tumor in one patient. Conclusion Resection of tumor is the choice of tumor in the most of benign and malignant brachial plexus tumors. Postoperative outcomes are related to grade of resection at surgery and pathological features of tumor. PMID:23091673

    This presentation is to increase awareness of the potential for brachial plexus injury during prolonged combined plastic surgery procedures. A case of brachial plexus neuropraxia in a 26-year-old obese patient following a prolonged combined plastic surgery procedure was encountered. Nerve palsy due to faulty positioning on the operating table is commonly seen over the elbow and popliteal fossa. However, injury to the brachial plexus has been a recently reported phenomenon due to the increasing number of laparoscopic and robotic procedures. Brachial plexus injury needs to be recognised as a potential complication of prolonged combined plastic surgery. Preventive measures are discussed. PMID:25593443

    The choroid plexus (CP) of brain ventricles forms the blood-cerebrospinal fluid (blood-CSF) barrier that is involved in many diseases affecting the central nervous system (CNS). We used ED1 and ED2 immunostaining to investigate epiplexus cell changes in rat CP after chronic constriction injury (CCI). In contrast to naïve CP, the CP of sham-operated rats showed an increase in the number of ED1+ cells of a similar magnitude during all periods of survival up to 3 weeks, while the number of ED2+ increased only at 3 days from operation. In comparison to naïve and sham-operated animals, the number of ED1+ and ED2+ cells in the epiplexus position increased with the duration of nerve compression. We detected no or negligible cell proliferation in the CP after sham- or CCI-operation. This suggests that increased number of ED1+ and ED2+ cells in the epiplexus position of the CP is derived from peripheral monocytes passing through altered blood-CSF barrier. The changes in epiplexus cells indicate that the CP reacts to tissue injury after the surgical approach itself and that the response to peripheral nerve lesion is greater. This suggests a role for an altered blood-CSF barrier allowing for propagation of signal molecules from damaged tissue and nerve to the CNS. PMID:27291457

    Complex distal femoral fractures in the young patient often occur as a result of high velocity trauma. Timely recognition and treatment is everything in such a situation, and it needs a robust staged management pathway to optimize the chance of limb preservation. We report a case of a motorcyclist admitted to the department of orthopedics at Chambery hospital, France, with a complex comminuted and open distal femoral fracture of the left leg, associated with a brachial plexus injury to the ipsilateral upper limb. On arrival to the emergency department, damage control stabilization and surgery was commenced, debridement of contaminated non-viable tissue, abundant antiseptic lavage and application of external fixation coupled with the use of antibiotic spacer. Following normalization of inflammatory markers and ensuring no clinical signs of infection, subsequent management consisted of joint reconstruction to achieve a functional knee. The external fixator and femoral spacer was removed and a modular megaprosthesis was implanted with a lateral gastrocnemius flap to cover the exposed knee joint and reinforce the extensor apparatus. Nerve graft to the left brachial plexus injury was performed at University Hospital of Grenoble. Our patient entered an intensive rehabilitation program and at 1 year follow-up achieved good knee function and sensation to the left upper limb. PMID:26421102

    Introduction This study was aimed to compare the axillary approach performed through multiple injection method and vertical infraclavicular approach performed through single injection method in terms of the sensory and motor block onset, quality, and extent of blocks of brachial plexus in uremic patients who underwent arteriovenous fistula surgery. Methods Forty patients scheduled for creation of arteriovenous fistula with axillary brachial plexus block (group AX, n = 20) or infraclavicular brachial plexus block (IC group, n = 20) were examined. The median, radial, ulnar, and musculocutaneous nerves were selectively localized by nerve stimulation. The volume of the local anesthetics was calculated based on the height of each patient, and the volume determined was prepared by mixing 2% lidocaine and 0.5% bupivacaine in equal proportions. Sensory and motor block were assessed at 3, 6, 9, 12, 15, 18, and 30th min and their durations were measured. Results While the adequate sensory and motor block rate with axillary approach was 100% in musculocutaneous, median, radial, ulnar and medial antebrachial cutaneous nerves, it was 65% in axillary nerve, 80% in intercostobrachial nerve and 95% in medial brachial cutaneous nerve. This rate was found to be 100% for all the nerves with infraclavicular approach. Conclusion For arteriovenous fistula surgeries in uremic patients, both axillary approach performed through multiple injection method and vertical infraclavicular approach performed through single injection method can be used successfully; however, for the short performance of the procedure, infraclavicular block may be preferred.

    OBJECTIVE Transfer of the spinal accessory nerve to the suprascapular nerve is a common procedure, performed to reestablish shoulder motion in patients with total brachial plexus palsy. However, the results of this procedure remain largely unknown. METHODS Over an 11-year period (2002-2012), 257 patients with total brachial plexus palsy were operated upon in the authors' department by a single surgeon and had the spinal accessory nerve transferred to the suprascapular nerve. Among these, 110 had adequate follow-up and were included in this study. Their average age was 26 years (SD 8.4 years), and the mean interval between their injury and surgery was 5.2 months (SD 2.4 months). Prior to 2005, the suprascapular and spinal accessory nerves were dissected through a classic supraclavicular L-shape incision (n = 29). Afterward (n = 81), the spinal accessory and suprascapular nerves were dissected via an oblique incision, extending from the point at which the plexus crossed the clavicle to the anterior border of the trapezius muscle. In 17 of these patients, because of clavicle fractures or dislocation, scapular fractures or retroclavicular scarring, the incision was extended by detaching the trapezius from the clavicle to expose the suprascapular nerve at the suprascapular fossa. In all patients, the brachial plexus was explored and elbow flexion reconstructed by root grafting (n = 95), root grafting and phrenic nerve transfer (n = 6), phrenic nerve transfer (n = 1), or third, fourth, and fifth intercostal nerve transfer. Postoperatively, patients were followed for an average of 40 months (SD 13.7 months). RESULTS Failed recovery, meaning less than 30° abduction, was observed in 10 (9%) of the 110 patients. The failure rate was 25% between 2002 and 2004, but dropped to 5% after the staged/extended approach was introduced. The mean overall range of abduction recovery was 58.5° (SD 26°). Comparing before and after distal suprascapular nerve exploration (2005-2012), the

    ABSTRACT Purpose: Most children with severe birth-related brachial plexus injury (BRBPI) have some functional impairment, but information on the impact of BRBPI on coordination and balance is limited. The study's purpose was to determine whether children with BRBPI exhibit deficits in body coordination and balance. Method: A prospective cohort study involving 39 children with BRBPI aged 5–15 years was conducted. Range of motion, strength, active movement, and balance and coordination motor skills were assessed using the Bruininks–Oseretsky Test of Motor Proficiency, Second Edition (BOT-2), and the Movement Assessment Battery for Children—Second Edition (MABC-2). A self-report measure of physical disability, the Activities Scale for Kids—Performance Version (ASKp), was also administered. Results: Participants scored a mean of 44.72 on the BOT-2 Body Coordination composite subtest; scores can range from 20 to 80. Eleven participants (28.2%) scored below average on this test. Participants scored a mean of 7.3 on the Balance subtest of the MABC-2; scores can range from 1 to 19. Twenty-six participants (66.7%) scored below average on this test. Of 38 participants, 25 (65.8%) had an ASKp score indicating some level of disability (<95/100); we found a statistically significant difference in balance (p=0.007) between these 25 participants and those without disability (ASKp score 95–100). Conclusions: The majority of our study population scored in the categories of at risk or significant difficulty for balance on the MABC-2. Balance rehabilitation may be a valuable treatment adjunct for children with BRBPI. PMID:25931660

    Objective: To evaluate the outcome of modified Quad procedure in preteen and teen patients with brachial plexus birth palsy. Background: We have previously demonstrated a significant improvement in shoulder abduction, resulting from the modified Quad procedure in children (mean age 2.5 years; range, 0.5–9 years) with obstetric brachial plexus injury. Methods: We describe in this report the outcome of 16 patients (6 girls and 10 boys; 7 preteen and 9 teen) who have undergone the modified Quad procedure for the correction of the shoulder function, specifically abduction. The patients underwent transfer of the latissimus dorsi and teres major muscles, release of contractures of subscapularis pectoralis major and minor, and axillary nerve decompression and neurolysis (the modified Quad procedure). Mean age of these patients at surgery was 13.5 years (range, 10.1–17.9 years). Results: The mean preoperative total Mallet score was 14.8 (range, 10–20), and active abduction was 84° (range, 20°–140°). At a mean follow-up of 1.5 years, the mean postoperative total Mallet score increased to 19.7 (range, 13–25, P < .0001), and the mean active abduction improved to 132° (range, 40°–180°, P < .0003). Conclusion: The modified Quad procedure greatly improves not only the active abduction but also other shoulder functions in preteen and teen patients, as this outcome is the combined result of decompression and neurolysis of the axillary nerve and the release of the contracted internal rotators of the shoulder.

    PubMed Central

    2013-01-01

    Brachial plexus injury is a rare complication during operation and anesthesia; it can occur as a result of various mechanisms such as inappropriate positioning, over-abduction and stretching the upper limbs. Brachial plexus injury can cause the poor function of the upper limb before recovery, and sometimes serious injury is unable to completely recovered the function permanently. Here, we report a female breast cancer patient who sustained a left brachial plexus palsy after modified radical mastectomy with immediate breast reconstruction with latissimusdorsi flap (LDF). The patient had fully recovered with normal function of her left upper limb six months postoperation after conservative treatment. PMID:24127915

    Objective To evaluate sociodemographic and clinical aspects of patients undergoing operations due to traumatic lesions of the brachial plexus. Method This was a retrospective study in which the medical files of a convenience sample of 48 patients operated between 2000 and 2010 were reviewed. The following were evaluated: (1) range of motion (ROM) of the shoulder, elbow and wrist/hand, in degrees; (2) grade of strength of the shoulder, elbow and wrist/hand; (3) sensitivity; and (4) visual analogue scale (VAS) (from 0 to 10). The Student's t, chi-square, Friedman, Wilcoxon and Kruskal–Wallis tests were used (p < 0.05). Results The patients’ mean age was 30.6 years; 60.4% of them had suffered motorcycle accidents and 52.1%, multiple trauma. The mean length of time until surgery was 8.7 months (range: 2–48). Thirty-one patients (64.6%) presented complete rupture of the plexus. The frequent operation was neurosurgery in 39 cases (81.3%). The ROM achieved was ≥30° in 20 patients (41.6%), with a range from 30° to 90° and mean of 73° (p = 0.001). Thirteen (27.1%) already had shoulder strength ≥M3 (p = 0.001). Twenty-seven patients (56.2%) had elbow flexion ≥80°, with a range from 30° to 160° and mean of 80.6° (p < 0.001). Twenty-two had strength ≥M3 (p < 0.001). Twenty-two patients (45.8%) had wrist extension ≥30° starting from flexion of 45°, with a range from 30° to 90° and mean of 70° (p = 0.003). Twenty-seven (56.3%) presented wrist/hand extension strength ≥M3 (p = 0.002). Forty-five (93.8%) had hypoesthesia and three (6.2%) had anesthesia (p = 0.006). The initial VAS was 4.5 (range: 1.0–9.0) and the final VAS was 3.0 (range: 1.0–7.0) (p < 0.001). Conclusion Traumatic lesions of the brachial plexus were more prevalent among young adults (21–40 years), men, people living in urban areas, manual workers and motorcycle accidents, with multiple trauma and total rupture of the plexus.

    OBJECTIVE: To investigate the feasibility of using free gracilis muscle transfer along with the brachialis muscle branch of the musculocutaneous nerve to restore finger and thumb flexion in lower trunk brachial plexus injury according to an anatomical study and a case report. METHODS: Thirty formalin-fixed upper extremities from 15 adult cadavers were used in this study. The distance from the point at which the brachialis muscle branch of the musculocutaneous nerve originates to the midpoint of the humeral condylar was measured, as well as the length, diameter, course and branch type of the brachialis muscle branch of the musculocutaneous nerve. An 18-year-old male who sustained an injury to the left brachial plexus underwent free gracilis transfer using the brachialis muscle branch of the musculocutaneous nerve as the donor nerve to restore finger and thumb flexion. Elbow flexion power and hand grip strength were recorded according to British Medical Research Council standards. Postoperative measures of the total active motion of the fingers were obtained monthly. RESULTS: The mean length and diameter of the brachialis muscle branch of the musculocutaneous nerve were 52.66±6.45 and 1.39±0.09 mm, respectively, and three branching types were observed. For the patient, the first gracilis contraction occurred during the 4th month. A noticeable improvement was observed in digit flexion one year later; the muscle power was M4, and the total active motion of the fingers was 209°. CONCLUSIONS: Repairing injury to the lower trunk of the brachial plexus by transferring the brachialis muscle branch of the musculocutaneous nerve to the anterior branch of the obturator nerve using a tension-free direct suture is technically feasible, and the clinical outcome was satisfactory in a single surgical patient.

    Purpose To assess brachial plexus magnetic resonance (MR) imaging features and limb-girdle muscle abnormalities as signs of muscle denervation in patients with amyotrophic lateral sclerosis (ALS). Materials and Methods This study was approved by the local ethical committees on human studies, and written informed consent was obtained from all subjects before enrollment. By using an optimized protocol of brachial plexus MR imaging, brachial plexus and limb-girdle muscle abnormalities were evaluated in 23 patients with ALS and clinical and neurophysiologically active involvement of the upper limbs and were compared with MR images in 12 age-matched healthy individuals. Nerve root and limb-girdle muscle abnormalities were visually evaluated by two experienced observers. A region of interest-based analysis was performed to measure nerve root volume and T2 signal intensity. Measures obtained at visual inspection were analyzed by using the Wald χ(2) test. Mean T2 signal intensity and volume values of the regions of interest were compared between groups by using a hierarchical linear model, accounting for the repeated measurement design. Results The level of interrater agreement was very strong (κ = 0.77-1). T2 hyperintensity and volume alterations of C5, C6, and C7 nerve roots were observed in patients with ALS (P < .001 to .03). Increased T2 signal intensity of nerve roots was associated with faster disease progression (upper-limb Medical Research Council scale progression rate, r = 0.40; 95% confidence interval: 0.001, 0.73). Limb-girdle muscle alterations (ie, T2 signal intensity alteration, edema, atrophy) and fat infiltration also were found, in particular, in the supraspinatus muscle, showing more frequent T2 signal intensity alterations and edema (P = .01) relative to the subscapularis and infraspinatus muscles. Conclusion Increased T2 signal intensity and volume of brachial nerve roots do not exclude a diagnosis of ALS and suggest involvement of the peripheral

    By virtue of its ability to regulate the composition of cerebrospinal fluid (CSF), the choroid plexus (CP) is ideally suited to instigate a rapid response to traumatic brain injury (TBI) by producing growth regulatory proteins. For example, Esophageal Cancer Related Gene-4 (Ecrg4) is a tumor suppressor gene that encodes a hormone-like peptide called augurin that is present in large concentrations in CP epithelia (CPe). Because augurin is thought to regulate senescence, neuroprogenitor cell growth and differentiation in the CNS, we evaluated the kinetics of Ecrg4 expression and augurin immunoreactivity in CPe after CNS injury. Adult rats were injured with a penetrating cortical lesion and alterations in augurin immunoreactivity were examined by immunohistochemistry. Ecrg4 gene expression was characterized by in situ hybridization. Cell surface augurin was identified histologically by confocal microscopy and biochemically by sub-cellular fractionation. Both Ecrg4 gene expression and augurin protein levels were decreased 24–72 hrs post-injury but restored to uninjured levels by day 7 post-injury. Protein staining in the supraoptic nucleus of the hypothalamus, used as a control brain region, did not show a decrease of auguin immunoreactivity. Ecrg4 gene expression localized to CPe cells, and augurin protein to the CPe ventricular face. Extracellular cell surface tethering of 14 kDa augurin was confirmed by cell surface fractionation of primary human CPe cells in vitro while a 6–8 kDa fragment of augurin was detected in conditioned media, indicating release from the cell surface by proteolytic processing. In rat CSF however, 14 kDa augurin was detected. We hypothesize the initial release and proteolytic processing of augurin participates in the activation phase of injury while sustained Ecrg4 down-regulation is dysinhibitory during the proliferative phase. Accordingly, augurin would play a constitutive inhibitory function in normal CNS while down regulation of Ecrg4

    The choroid plexus (CPx) may be an important site of viral dissemination since monocytes and dendritic cells in its stroma are infected with HIV in AIDS patients and since the ratio of CPx to brain infection is more than 2 : 1. In order to see if CPx infection also develops in asymptomatic (ASY) HIV-infected patients, we examined archival formalin-fixed brain and CPx from 14 AIDS and seven ASY cases, using routine histology, immunohistochemistry for HIV gp41, and DNA extraction and gene amplification for HIV DNA. Eight of 14 AIDS (57%) had HIV-positive cells in the CPx and four (29%) had HIV encephalitis. Two of seven ASY cases (29%) had HIV-positive cells in the CPx but none had HIV encephalitis. Extracted DNA from brain, CPx and systemic organs of five ASY cases was amplified by nested PCR with or without Southern blotting for HIV env gene. It was positive in systemic organs in five cases; in CPx in four cases; and in brain in one case. This study shows that the CPx is a site of HIV infection in ASY patients and that the frequency of CPx infection is higher than seen in brain in both AIDS and ASY cases. The results are consistent with the hypothesis that the CPx may be a site for hematogeneous spread and a reservoir for HIV infection during the period of clinical latency. PMID:10602407

    The intrinsic cardiac autonomic nervous system (ganglionated plexuses [GP]) plays a significant role in the initiation and maintenance of atrial fibrillation (AF) in both experimental models and AF patients. Left atrial GP, located in epicardial fat pads and the ligament of Marshall, contain afferent neurons from the atrial myocardium and the central autonomic nervous system, efferent neurons (cholinergic and adrenergic neurons), and interconnecting neurons, which allow communication between GP. Stimulation of the GP produces both parasympathetic stimulation (markedly shortens action potential duration) and sympathetic stimulation (increases calcium transient) in the pulmonary vein (PV) myocardium and atrial myocardium. In a canine model, GP stimulation resulted in early afterdepolarizations, and calcium transient triggered firing in the adjacent PV and initiated AF. Fractionated atrial potentials (FAP) were consistently located in the left atrium close to the stimulated GP. Ablation of the stimulated GP eliminated the FAP surrounding the GP. In patients with paroxysmal AF, epicardial and endocardial high-frequency stimulation produced a positive vagal response (transient AV block during AF and hypotension), allowing the identification and localization of five major left atrial GP (superior left GP, inferior left GP, Marshall tract GP, anterior right GP, inferior right GP). High-density electroanatomic maps of the left atrium and PVs obtained during AF showed the FAP are located in four main left atrial areas (left atrial appendage ridge FAP area, superior-left FAP area, inferoposterior FAP area, anterior-right FAP area). All five GP are located within one of the four FAP areas. In 63 patients with paroxysmal AF, GP ablation alone (before PV antrum isolation) significantly decreased the occurrence of PV firing (47/63 patients before ablation vs 9/63 patients after ablation, P <.01). GP ablation also decreased the inducibility of sustained AF (43/63 patients vs 23

    Purpose: To perform a comprehensive literature review and analysis of cases dealing with choroid plexus carcinoma (CPC) to determine the optimal radiotherapy (RT) treatment field. Methods and Materials: A PubMed search of English language articles from 1979 to 2008 was performed, yielding 33 articles with 56 patients who had available data regarding RT treatment field. The median age at diagnosis was 2.7 years (range, 1 month-53 years). Of 54 patients with data regarding type of surgery, 21 (38.9%) had complete resection. Chemotherapy was delivered to 27 (48%) as part of initial therapy. The RT treatment volume was the craniospinal axis in 38 (68%), whole brain in 9 (16%), and tumor/tumor bed in 9 (16%). Median follow-up for surviving patients was 40 months. Results: The 5-year overall survival and progression-free survival (PFS) rates were 59.5% and 37.2%, respectively. Complete resection (p = 0.035) and use of craniospinal irradiation (CSI; p = 0.025) were found to positively affect PFS. The 5-year PFS for patients who had CSI vs. whole brain and tumor/tumor bed RT were 44.2% and 15.3%. For the 19 patients who relapsed, 9 (47%) had a recurrence in the RT field, 6 (32%) had a recurrence outside the RT field, and 4 (21%) had a recurrence inside and outside the irradiated field. Conclusion: Patients with CPC who received CSI had better PFS compared with those receiving less than CSI. This study supports the use of CSI in the multimodality management of patients with CPC.

    Magnetic resonance (MR) neurography comprises an evolving group of techniques with the potential to allow optimal noninvasive evaluation of many abnormalities of the brachial plexus. MR neurography is clinically useful in the evaluation of suspected brachial plexus traumatic injuries, intrinsic and extrinsic tumors, and post-radiogenic inflammation, and can be particularly beneficial in pediatric patients with obstetric trauma to the brachial plexus. The most common MR neurographic techniques for displaying the brachial plexus can be divided into two categories: structural MR neurography; and microstructural MR neurography. Structural MR neurography uses mainly the STIR sequence to image the nerves of the brachial plexus, can be performed in 2D or 3D mode, and the 2D sequence can be repeated in different planes. Microstructural MR neurography depends on the diffusion tensor imaging that provides quantitative information about the degree and direction of water diffusion within the nerves of the brachial plexus, as well as on tractography to visualize the white matter tracts and to characterize their integrity. The successful evaluation of the brachial plexus requires the implementation of appropriate techniques and familiarity with the pathologies that might involve the brachial plexus. PMID:21763092

    Objective: To present the unique case of a collegiate wrestler with C7 neurologic symptoms due to T1–T2 disc herniation. Background: A 23-year-old male collegiate wrestler injured his neck in a wrestling tournament match and experienced pain, weakness, and numbness in his left upper extremity. He completed that match and 1 additional match that day with mild symptoms. Evaluation by a certified athletic trainer 6 days postinjury showed radiculopathy in the C7 distribution of his left upper extremity. He was evaluated further by the team physician, a primary care physician, and a neurosurgeon. Differential Diagnosis: Cervical spine injury, stinger/burner, peripheral nerve injury, spinal cord injury, thoracic outlet syndrome, brachial plexus radiculopathy. Treatment: The patient initially underwent nonoperative management with ice, heat, massage, electrical stimulation, shortwave diathermy, and nonsteroidal anti-inflammatory drugs without symptom resolution. Cervical spine radiographs were negative for bony pathologic conditions. Magnetic resonance imaging showed evidence of T1–T2 disc herniation. The patient underwent surgery to resolve the symptoms and enable him to participate for the remainder of the wrestling season. Uniqueness: Whereas brachial plexus radiculopathy commonly is seen in collision sports, a postfixed brachial plexus in which the T2 nerve root has substantial contribution to the innervation of the upper extremity is a rare anatomic variation with which many health care providers are unfamiliar. Conclusions: The injury sustained by the wrestler appeared to be C7 radiculopathy due to a brachial plexus traction injury. However, it ultimately was diagnosed as radiculopathy due to a T1–T2 thoracic intervertebral disc herniation causing impingement of a postfixed brachial plexus and required surgical intervention. Athletic trainers and physicians need to be aware of the anatomic variations of the brachial plexus when evaluating and caring for

    Myxoinflammatory fibroblastic sarcoma is a rare sarcoma that develops in patients of all ages, which usually presents as a slow-growing painless mass in the distal extremities. To date, myxoinflammatory fibroblastic sarcoma with invasion of the brachial plexus has rarely been reported in the literature. In this study, a case of large cervicothoracic sarcoma, which invaded the brachial plexus, is presented. The patient reported no sensory disturbance or dyskinesia. The tumor was completely resected without injury of the brachial plexus. The postoperative histological diagnosis was myxoinflammatory fibroblastic sarcoma. Follow-up examination performed 24 months after surgery revealed no tumor recurrence and no sensory disturbance or dyskinesia was reported. This study presents a rare case of large myxoinflammatory fibroblastic sarcoma with brachial plexus invasion that was successfully managed by surgery. PMID:27588121

    Severe brachial plexus injuries are rare in sports, but they have catastrophic results with a significant loss of function in the involved upper extremity. Nerve root avulsions must be timely managed with prompt evaluation, accurate diagnosis, and surgical treatment to optimize the potential for a functional outcome. This case report describes the mechanism of injury, diagnostic evolution, surgical management, and rehabilitation of a college football player who sustained a traumatic complete nerve root avulsion of C5 and C6 (upper trunk of the brachial plexus). Diagnostics included clinical evaluation, magnetic resonance imaging, computed tomography myelogram, and electromyogram. Surgical planning included nerve grafting and neurotization (nerve transfer). Rehabilitation goals were to bring the hand to the face (active biceps function), to stabilize the shoulder for abduction and flexion, and to reduce neuropathic pain. Direct current stimulation, bracing, therapeutic exercise, and biofeedback were used to maximize the use of the athlete’s upper extremity. Although the athlete could not return to sport or normal function by most standards, his results were satisfactory in that he regained an ability to perform many activities of daily living.

    In the study, the functional recovery and relative comprehensive quality of life of cases of global brachial plexus treated with free functioning muscle transfers were investigated. Patients who received functioning gracilis muscle transfer between August 1999 and October 2014 to reconstruct elbow flexion, wrist and fingers extension were recruited. The mean age of the patients was 26.36 (range, 16–42) years. The mean period of time from gracilis transfer to the last follow-up was 54.5 months (range, 12–185 months). Muscle power, active range of motion of the elbow flexion, wrist extension, and total active fingers extension were recorded. SDS, SAS and DASH questionnaires were given to estimate patients’ quality of life. 35.71% reported good elbow flexion and 50.00% reported excellent elbow flexion. The average ROM of the elbow flexion was 106.5° (range, 0–142°) and was 17.00° (range, 0–72°) for wrist extension. The average DASH score was 51.14 (range, 17.5–90.8). The prevalence of anxiety and depression were 42.86% and 45.24%. Thrombosis and bowstringing were the most common short and long-term complications. Based on these findings, free gracilis transfer using accessory nerve as donor nerve is a satisfactory treatment to reconstruct the elbow flexion and wrist extension in global-brachial-plexus-injured patients.

    The Karolinska Institutet 200-year anniversary symposium on injuries to the spinal cord and peripheral nervous system gathered expertise in the spinal cord, spinal nerve, and peripheral nerve injury field spanning from molecular prerequisites for nerve regeneration to clinical methods in nerve repair and rehabilitation. The topics presented at the meeting covered findings on adult neural stem cells that when transplanted to the hypoglossal nucleus in the rat could integrate with its host and promote neuron survival. Studies on vascularization after intraspinal replantation of ventral nerve roots and microarray studies in ventral root replantation as a tool for mapping of biological patterns typical for neuronal regeneration were discussed. Different immune molecules in neurons and glia and their very specific roles in synapse plasticity after injury were presented. Novel strategies in repair of injured peripheral nerves with ethyl-cyanoacrylate adhesive showed functional recovery comparable to that of conventional epineural sutures. Various aspects on surgical techniques which are available to improve function of the limb, once the nerve regeneration after brachial plexus lesions and repair has reached its limit were presented. Moreover, neurogenic pain after amputation and its treatment with mirror therapy were shown to be followed by dramatic decrease in phantom limb pain. Finally clinical experiences on surgical techniques to repair avulsed spinal nerve root and the motoric as well as sensoric regain of function were presented. PMID:21629875

    More and more higher development of civilisation causes constant lengthening of life in humans. Changes, which occur during growing old of organism predispose to increased risk of trauma. Financial cost of medical treatment of injuries in elderly are higher and higher. Degenerative disease of joints, osteoporosis, earlier body injuries and co-existing other diseases are important risk factors of trauma. Deficiencies of eyesight, hearing and prolonged time reaction are other strengthening risk of trauma. Falls and motor-vehicle accidents are the most frequent causes of trauma in elderly. Distal radius fracture, fracture of the proximal femur bone and compressive vertebral fracture of spine are typical fractures in the skeletal system. Head injuries are the most frequent cause of death in this group of patients. Limited functional reserves, especially in the respiratory and circulatory system brings difficulties in the treatment of even not dangerous injuries of chest and increases risks of infectious complications in respiratory system and finally may lead to organ failure. Elderly patients need more precise physical examination and diagnostics because essential information from the patient's history are often difficult to obtain. Indications to hospitalisation should be often widened even at not dangerous injuries, because the patients may demand intensive analgesic treatment and nursing. Necessity of care provided by other persons, poor care in household conditions, and inadequate social circumstances extend also indications to hospitalisation. There is a need to creation of nursing care departments for considerable group of injured persons who finished proper hospital-treatment, but because of the above-mentioned reasons cannot exist at home.

    Interscalene brachial plexus block (IBPB) has been widely used in shoulder surgical procedures. The incidence of postoperative neural injury has been estimated to be as high as 3 %. We report a long-term neurologic deficit after a nerve stimulator assisted brachial plexus block. A 55 year-old male, with right shoulder impingement syndrome was scheduled for elective surgery. The patient was given an oral dose of 10 mg of diazepam prior to the nerve stimulator assisted brachial plexus block. The patient immediately complained, as soon as the needle was placed in the interscalene area, of a sharp pain in his right arm and he was sedated further. Twenty-four hours later, the patient complained of severe shoulder and arm pain that required an increased dose of analgesics. Severe peri-scapular atrophy developed over the following days. Electromyography studies revealed an upper trunk plexus injury with severe denervation of the supraspinatus, infraspinatus and deltoid muscles together with a moderate denervation of the biceps brachii muscle. Chest X-rays showed a diaphragmatic palsy which was not present post operatively. Pulmonary function tests were also affected. Phrenic nerve paralysis was still present 18 months after the block as was dysfunction of the brachial plexus resulting in an inability to perform flexion, abduction and external rotation of the right shoulder. Severe brachial plexopathy was probably due to a local anesthetic having been administrated through the perineurium and into the nerve fascicles. Severe brachial plexopathy is an uncommon but catastrophic complication of IBPB. We propose a clinical algorithm using ultrasound guidance during nerve blocks as a safer technique of regional anesthesia. PMID:25744163

    Purpose: To evaluate interobserver variability for contouring the brachial plexus as an organ-at-risk (OAR) and to analyze its potential dosimetric consequences in patients treated with intensity-modulated radiotherapy (IMRT) for head-and-neck cancer. Methods and Materials: Using the Radiation Therapy Oncology Group (RTOG)-endorsed brachial plexus contouring atlas, three radiation oncologists independently delineated the OAR on treatment planning computed-tomography (CT) axial scans from 5 representative patients undergoing IMRT to a prescribed dose of 70 Gy for head-and-neck cancer. Dose-volume histograms for the brachial plexus were calculated, and interobserver differences were quantified by comparing various dosimetric statistics. Qualitative analysis was performed by visually assessing the overlapping contours on a single beam's eye view. Results: Brachial plexus volumes for the 5 patients across observers were 26 cc (18-35 cc), 25 cc (21-30 cc), 29 cc (28-32 cc), 29 cc (23-38 cc), and 29 cc (23-34 cc). On qualitative analysis, minimal variability existed except at the inferolateral portion of the OAR, where slight discrepancies were noted among the physicians. Maximum doses to the brachial plexus ranged from 71.6 to 72.6 Gy, 75.2 to 75.8 Gy, 69.1 to 71.0 Gy, 76.4 to 76.9 Gy, and 70.6 to 71.4 Gy. Respective volumes receiving doses greater than 60 Gy (V60) were 8.6 to 10.9 cc, 6.2 to 8.1 cc, 8.2 to 11.6 cc, 8.3 to 10.5 cc, and 5.6 to 9.8 cc. Conclusion: The RTOG-endorsed brachial plexus atlas provides a consistent set of guidelines for contouring this OAR with essentially no learning curve. Adoption of these contouring guidelines in the clinical setting is encouraged.

    Ulnar deviation deformity of the wrist in patients with birth brachial plexus palsy is an important cosmetic concern among the patients and their relatives; especially in the patients who have recovered the basic limb functions. Though there is ample literature available regarding the management of the shoulder deformity there is paucity of literature regarding management of wrist ulnar deviation deformity. We report our experience with correction of this deformity in five cases with isolated ulnar deviation deformity without forearm rotational deformity or weakness of the wrist muscles. All the patients underwent extensor carpi ulnaris (ECU) to extensor carpi radialis longus (ECRL) tendon transfer. At a minimum of 18 months follow-up all the patients and their families were satisfied with the cosmetic appearance of the limb. Correction of the deformity improves the appearance of the limb, improves self-confidence of the child, and allows them to integrate well into the society. Interestingly, the patients expressed improvement in their grip strength and overall hand function after this surgery. The notable functions which improved were easy reach of the hand-to-mouth for feeding and easy handling of the things requiring bimanual activities. Although the main aim of this operation was to correct the appearance of the hand it was found to be also functionally useful by the patients and hence we are encouraged to report it for wider use. The results were maintained during the follow-up period of as long as 47 months. PMID:25609294

    Background The management of brachial plexus injuries due to gunshot wounds is a surgical challenge. Better surgical strategies based on clinical and electrophysiological patterns are needed. The aim of this study is to clarify the factors which may influence the surgical technique and outcome of the brachial plexus lesions caused by gunshot injuries. Methods Two hundred and sixty five patients who had brachial plexus lesions caused by gunshot injuries were included in this study. All of them were male with a mean age of 22 years. Twenty-three patients were improved with conservative treatment while the others underwent surgical treatment. The patients were classified and managed according to the locations, clinical and electrophysiological findings, and coexisting lesions. Results The wounding agent was shrapnel in 106 patients and bullet in 159 patients. Surgical procedures were performed from 6 weeks to 10 months after the injury. The majority of the lesions were repaired within 4 months were improved successfully. Good results were obtained in upper trunk and lateral cord lesions. The outcome was satisfactory if the nerve was intact and only compressed by fibrosis or the nerve was in-contunuity with neuroma or fibrosis. Conclusion Appropriate surgical techniques help the recovery from the lesions, especially in patients with complete functional loss. Intraoperative nerve status and the type of surgery significantly affect the final clinical outcome of the patients. PMID:19627573

    Capillary plexuses are commonly regarded as reliable networks for blood flow and robust oxygen delivery to hypoxia sensitive tissues. They have high levels of redundancy to assure adequate blood supply when one or more of the capillaries in the network are blocked by a clot. However, despite having extensive capillary plexuses, many vital organs are often subject to secondary organ injury in patients with severe inflammation. Recent studies have suggested that neutrophils play a role in this pathology, even though their precise contribution remains elusive. Here we investigate the effect of chromatin fibres released from overly-activated neutrophils (neutrophil extracellular traps, NETs) on the flow of blood through microfluidic networks of channels replicating geometrical features of capillary plexuses. In an in vitro setting, we show that NETs can decouple the traffic of red blood cells from that of plasma in microfluidic networks. The effect is astonishingly disproportionate, with NETs from less than 200 neutrophils resulting in more than half of a 0.6 mm(2) microfluidic network to become void of red blood cell traffic. Importantly, the NETs are able to perturb the blood flow in capillary networks despite the presence of anti-coagulants. If verified to occur in vivo, this finding could represent a novel mechanism for tissue hypoxia and secondary organ injury during severe inflammation in patients already receiving antithrombotic and anticoagulant therapies.

    Regional anesthesia is favored in patients who undergo emergency extremity (limb) surgery, and specifically so in the absence of fasting status. In the absence of ultrasonic guidance, the nerve stimulator still remains a valuable tool in performing a brachial block, but its use is difficult in an emergency surgical patient and greater cautious approach is essential. We identified the supraclavicular plexus by the nerve stimulation-motor response technique as follows. Anterior chest muscles contractions, diaphragmatic contraction, deltoid contractions, and posterior shoulder girdle muscle contractions when identified were taken as “negative response” with decreasing stimulating current. A forearm muscle contraction, especially “wrist flexion” and “finger flexion” at 0.5 mA of current was taken as “positive response.” If no positive response was identified, the “elbow flexion” was considered as the final positive response for successful drug placement. The series of patients had difficulty for administering both general and regional anesthesia and we considered them as complex scenarios. The risk of the block failure was weighed heavily against the benefits of its success. The described series includes patients who had successful outcomes in the end and the techniques, merits, and risks are highlighted. PMID:26417145

    Interscalene brachial plexus block provides effective anesthesia and analgesia for shoulder surgery. One of the disadvantages of this technique is the risk of hemidiaphragmatic paresis, which can occur as a result of phrenic nerve block and can cause a decrease in the pulmonary function, limiting the use of the block in patients with reduced functional residual capacity or a preexisting pulmonary disease. However, it is generally transient and is resolved over the duration of the local anesthetic's action.We present a case of a patient who experienced prolonged hemidiaphragmatic paresis following a continuous interscalene brachial plexus block for the postoperative pain management of shoulder surgery, and suggest a mechanism that may have led to this adverse effect.Nerve injuries associated with peripheral nerve blocks may be caused by several mechanisms. Our findings suggest that perioperative nerve injuries can occur as a result of combined mechanical and chemical injuries. PMID:27310984

    The choroid plexus, located in brain ventricles, has received surprisingly little attention in clinical neuroscience. In morphometric brain analysis, we serendipitously found a 21% increase in choroid plexus volume in 12 patients suffering from complex regional pain syndrome (CRPS) compared with age- and gender-matched healthy subjects. No enlargement was observed in a group of 8 patients suffering from chronic pain of other etiologies. Our findings suggest involvement of the choroid plexus in the pathogenesis of CRPS. Since the choroid plexus can mediate interaction between peripheral and brain inflammation, our findings pinpoint the choroid plexus as an important target for future research of central pain mechanisms.

    The ischemia necrosis of limb frequently requires surgery of amputation. Lumbar plexus and sciatic nerve block is an ideal intra-operative anesthetic and post-operative antalgic technique for patients of amputation, especially for high-risk patients who have severe cardio-cerebrovascular diseases. However, the duration of analgesia of peripheral nerve block is hardly sufficient to avoid the postoperative pain and the usage of opioids. In this case, a 79-year-old man, with multiple cerebral infarcts, congestive heart failure, atrial flutter and syncope, was treated with an above knee amputation because of ischemia necrosis of his left lower limb. Dexmedetomidine 1 μg/kg was added to 0.33% ropivacaine for lumbar plexus and sciatic nerve block in this case for intra-operative anesthesia and post-operative analgesia. The sensory function was blocked fully for surgery and the duration of analgesia maintained 26 hours with haemodynamic stability and moderate sedation. The patient did not complain pain and require any supplementary analgesics after surgery. This case showed that adding 1 μg/kg dexmedetomidine to ropivacaine for lumbar plexus and sciatic nerve block may be a feasible and safe technique for high-risk patients for lower limb surgery of amputation.

    The objectives of this study were (1) epidemiological analysis of traumatic peripheral nerve injuries; (2) assessment of neuropathic pain and quality of life in patients affected by traumatic neuropathies. All consecutive patients with a diagnosis of traumatic neuropathies from four Italian centres were enrolled. Electromyography confirmed clinical level and site diagnosis of peripheral nerve injury. All patients were evaluated by disability scales, pain screening tools, and quality of life tests. 158 consecutive patients for a total of 211 traumatic neuropathies were analysed. The brachial plexus was a frequent site of traumatic injury (36%) and the radial, ulnar, and peroneal were the most commonly involved nerves with 15% of iatrogenic injuries. Seventy-two percent of the traumatic neuropathies were painful. Pain was present in 66% and neuropathic pain in 50% of all patients. Patients had worse quality of life scores than did the healthy Italian population. Moreover, there was a strong correlation between the quality of life and the severity of the pain, particularly neuropathic pain (Short Form-36 [SF-36] p < 0.005; Beck Depression Inventory [BDI] p < 0.0001). Traumatic neuropathies were more frequent in young males after road accidents, mainly in the upper limbs. Severe neuropathic pain and not only disability contributed to worsening the quality of life in patients with traumatic neuropathies. PMID:20626775

    Popliteal-artery injuries in the paediatric-trauma patient are uncommon, difficult to diagnose and with prolonged ischaemia lead to substantial complications. We report three cases of popliteal-vasculature injury in paediatric-trauma patients with diverse mechanisms of injury: blunt trauma, penetrating injury and a Salter-Harris I fracture. We present a range of the significant sequelae that can result from paediatric popliteal-artery injury, both physically and psychologically. It is imperative that clinicians have a high index of suspicion when confronted with paediatric patients with trauma around the knee and that popliteal-vasculature injuries are diagnosed early. If insufficiencies are detected, further imaging should be considered, but surgical exploration should not be delayed in the presence of ischaemia. PMID:22776610

    Pressure injuries burden patients and healthcare organisations, with some preventative practices having little impact on prevalence reduction. Patient participation in care may be an effective pressure injury prevention strategy, yet patient preferences are unknown. The aim of this interpretive study was to describe patients' perceptions of their current and future role in pressure injury prevention. Semi-structured interviews were conducted with 20 adult inpatients recruited from four medical units, at two Australian metropolitan hospitals. Interview data were analysed using content analysis, with three categories emerging: 'experiencing pressure injuries'; 'participating in pressure injury prevention'; and 'resourcing pressure injury prevention and treatment'. These categories reflect the complex nature of participants' pressure injury experience. The findings suggest participants gather pressure injury knowledge from first-hand and vicarious experience; knowledge they bring to hospital. Most participants preferred a proactive pressure injury prevention role. Many identified barriers in the healthcare environment that impeded their participation and affected their experience of pressure injuries and pressure injury prevention. If patient participation as a pressure injury prevention strategy is to be considered, nurses and organisations need to view patients as partners. PMID:24117711

    Here, we report successful anesthetic management of posterior cervical spinal fusion utilizing block of the frontal nerve, the greater occipital nerve, and the superficial cervical plexus in a patient with athetoid cerebral palsy. A 69-year-old woman (height 157 cm; weight 33 kg) with athetoid cerebral palsy was scheduled to undergo posterior cervical spinal fusion for cervical spondylotic myelopathy. After induction of general anesthesia, we performed tracheal intubation using the Pentax-AWS Airwayscope with a thin Intlock. After tracheal intubation, we used ropivacaine for the frontal nerve, greater occipital nerve, and superficial cervical plexus block. Anesthetic maintenance was performed with total intravenous anesthesia utilizing propofol and remifentanil. Continuous administration of dexmedetomidine was started during operation. Following surgery, smooth spontaneous ventilation was observed following uneventful extubation. No significant pain and no athetoid movement were observed under continuous administration of dexmedetomidine. PMID:26422967

    ObjectiveThe purpose of this study was to evaluate the feasibility, the initial accuracy, and the effects of the MR-guided neurolytic celiac plexus ablation as a method to treat cancer-induced chronic abdominal pain. Thirteen celiac plexus ablations were performed for 12 patients. A 0.23-T open MRI scanner with optical navigation was used for procedural guidance. As an adjunct to the MR-guided needle positioning, the needle location was confirmed with saline injection and consequent MR imaging (STIR sequence). The spread of the ablative injection material (alcohol-lidocaine mix) was observed by repeating this sequence after the therapeutic injection. Pain scores from seven patients (eight ablations) were used to assess the therapy effect. MR guidance allowed adequate needle positioning and visualization of injection material in all cases. The rest pain scores significantly decreased from 4 (median) at baseline to 1 (median) at 2 weeks (p < 0.05). Average and worst pain experienced during the past week were significantly lower at the 2-week time point compared with the baseline (p < 0.05). However, the intervention did not result in reduction of opioid use at 2 weeks.MR guidance is an accurate and safe method for celiac plexus ablation with positive therapeutic effect.

    Background and purpose - Although the results of primary total hip replacements (THRs) are generally excellent, sometimes serious complications arise. Some of these severe complications are considered to be patient injuries. We analyzed primary THR-related patient injuries in a nationwide setting. Patients and methods - We evaluated all the primary THR-related patient injury claims in Finland between 2008 and 2010. We used the original medical records and 2 nationwide registries, the Care Register for Social Welfare and Health Care and the Patient Injury Claim Register. Results - We identified 563 claims, 44% of which were compensated (n = 250). Of these 250 compensated claims, 79% were considered to be avoidable (treatment injuries) and 21% were severe unexpected infections (with a preoperative infection risk of less than 2%). The most common type of technical error was cup malposition (31%). High-volume hospitals (with an annual primary THR volume ≥ 400) had a lower patient injury rate. In lower-volume hospitals (with an annual primary THR volume of < 400), the relative risks (RRs) of patient injury for any reason, due to technical errors, or because of cup malposition were 2-fold (95% CI: 1.6-3.1), 4-fold (95% CI: 2.3-6.2), and 9-fold (95% CI: 3-28), respectively, compared to high-volume hospitals. Interpretation - Our study provides the first comprehensive nationwide data on THR-related patient injury types. Hospital volume was associated with the quality and quantity of errors detected. An annual hospital volume of ≥ 400 primary THRs was established as a protective factor against patient injuries. PMID:26808350

    Purpose: Data from a prospective screening protocol administered for patients previously irradiated for head-and-neck cancer was analyzed to identify dosimetric predictors of brachial plexus-associated neuropathy. Methods and Materials: Three hundred fifty-two patients who had previously completed radiation therapy for squamous cell carcinoma of the head and neck were prospectively screened from August 2007 to April 2013 using a standardized self-administered instrument for symptoms of neuropathy thought to be related to brachial plexus injury. All patients were disease-free at the time of screening. The median time from radiation therapy was 40 months (range, 6-111 months). A total of 177 patients (50%) underwent neck dissection. Two hundred twenty-one patients (63%) received concurrent chemotherapy. Results: Fifty-one patients (14%) reported brachial plexus-related neuropathic symptoms with the most common being ipsilateral pain (50%), numbness/tingling (40%), and motor weakness and/or muscle atrophy (25%). The 3- and 5-year estimates of freedom from brachial plexus-associated neuropathy were 86% and 81%, respectively. Clinical/pathological N3 disease (P<.001) and maximum radiation dose to the ipsilateral brachial plexus (P=.01) were significantly associated with neuropathic symptoms. Cox regression analysis revealed significant dose–volume effects for brachial plexus-associated neuropathy. The volume of the ipsilateral brachial plexus receiving >70 Gy (V70) predicted for symptoms, with the incidence increasing with V70 >10% (P<.001). A correlation was also observed for the volume receiving >74 Gy (V74) among patients treated without neck dissection, with a cutoff of 4% predictive of symptoms (P=.038). Conclusions: Dose–volume guidelines were developed for radiation planning that may limit brachial plexus-related neuropathies.

    Brachial plexus injuries, in all their severity and complexity, have been extensively studied. Although brachial plexus injuries are associated with serious and often definitive sequelae, many concepts have changed since the 1950s, when this pathological condition began to be treated more aggressively. Looking back over the last 20 years, it can be seen that the entire approach, from diagnosis to treatment, has changed significantly. Some concepts have become better established, while others have been introduced; thus, it can be said that currently, something can always be offered in terms of functional recovery, regardless of the degree of injury. Advances in microsurgical techniques have enabled improved results after neurolysis and have made it possible to perform neurotization, which has undoubtedly become the greatest differential in treating brachial plexus injuries. Improvements in imaging devices and electrical studies have allowed quick decisions that are reflected in better surgical outcomes. In this review, we intend to show the many developments in brachial plexus surgery that have significantly changed the results and have provided hope to the victims of this serious injury.

    Diabetes mellitus (DM) is associated with increased in-hospital morbidity and mortality in patients sustained traumatic injuries. Identification of risk factors of traumatic injuries that lead to hospital admissions and death in DM patients is crucial to set effective preventive strategies. We aimed to conduct a traditional narrative literature review to describe the role of hypoglycemia as a risk factor of driving and fall-related traumatic injuries. DM poses significant burden as a risk factor and predictor of worse outcomes in traumatic injuries. Although there is no consensus on the impact and clear hazards of hyperglycemia in comparison to the hypoglycemia, both extremes of DM need to be carefully addressed and taken into consideration for proper management. Moreover, physicians, patients, and concerned authorities should be aware of all these potential hazards to share and establish the right management plans. PMID:27162438

    Schizophrenia is recognized as a psychiatric disorder that causes the most pronounced disturbances of cognition and social integration. In the etiopathogenesis of the disease, genetic, neurobiological and vascular factors are involved. Functional integrity of the brain can be correlated with the integrity of the blood-brain barrier (BBB), and the dysfunction of this barrier is an indicator that suggests neurodevelopmental abnormalities, injuries of various etiologies and dysfunctions within the small vessels of the brain that disrupt the calcium homeostasis. Neuroimaging shows that in patients with poor evolution, cognitive dysfunction and therapeutic resistance, the presence of choroid plexus calcification associated with hippocampal, frontal, temporoparietal and cerebellar atrophies. Antipsychotics with high capacity to block D2 dopamine receptors (haloperidol model) can aggravate apoptotic mechanisms of the brain areas involved in cognition and disrupts the functional integrity of the BBB due to decreased of choroid plexus blood flow because of the narrowing of cerebral small vessels. Choroid plexus calcification may be a predictive indicator of poor evolution or of a neurodegenerative type. PMID:23771083

    Obstetric brachial plexus injuries (OBPP) are a relatively common stretch injury of the brachial plexus that occurs during delivery. Roughly 30 % of patients will not recover completely and will need a surgical repair. Two main treatment strategies have been used: primary surgery, consisting in exploring and reconstructing the affected portions of the brachial plexus within the first few months of the patient's life, and secondary procedures that include tendon or muscle transfers, osteotomies, and other orthopedic techniques. Secondary procedures can be done as the only surgical treatment of OBPP or after primary surgery, in order to minimize any residual deficits. Two things are crucial to achieving a good outcome: (1) the appropriate selection of patients, to separate those who will spontaneously recover from those who will recover only partially or not at all; and (2) a good surgical technique. The objective of the present review is to assess the published literature concerning certain controversial issues in OBPP, especially in terms of the true current state of primary and secondary procedures, their results, and the respective roles each plays in modern-day treatment of this complex pathology. Considerable published evidence compiled over decades of surgical experience favors primary nerve surgery as the initial therapeutic step in patients who do not recover spontaneously, followed by secondary surgeries for further functional improvement. As described in this review, the results of such treatment can greatly ameliorate function in affected limbs. For best results, multi-disciplinary teams should treat these patients. PMID:26615411

    Achalasia is a motor disorder of the oesopagus characterized by decrease in ganglion cell density in Auerbach's plexus. The cause of the lesion is unknown. This is to repeat on the occurrence of autoimmune phenomena in patients with achalasia, in particular circulating antibodies against Auerbach's plexus and its possible meaning. IgG-antibodies against Auerbach's plexus were determined by standard indirect immunofluorescence. Antibodies to the cytoplasm of Auerbach's plexus were found in 37 of 58 patients with achalasia at variable stages of the disease (I-IV) with a disease duration ranging from 1 to 20 years but only in 4 out of 54 healthy controls (specificity 93%, sensitivity 64%, p < 0.0001), and in none of 12 patients with Hirschsprung's disease as well as 12 patients with cancer of oesophagus and only in one of 11 patients with peptic oesophagitis as well as in one of 13 patients with myasthenia gravis. The present observations suggest that autoimmunity to Auerbach's plexus plays a role in the pathogenesis of achalasia, the mechanism of action is unknown. PMID:8747084

    Acute kidney injury (AKI) occurs commonly in patients with advanced cirrhosis and negatively impacts pre- and post-transplant outcomes. Physiologic changes that occur in patients with decompensated cirrhosis with ascites, place these patients at high risk of AKI. The most common causes of AKI in cirrhosis include prerenal injury, acute tubular necrosis (ATN), and the hepatorenal syndrome (HRS), accounting for more than 80% of AKI in this population. Distinguishing between these causes is particularly important for prognostication and treatment. Treatment of Type 1 HRS with vasoconstrictors and albumin improves short term survival and renal function in some patients while awaiting liver transplantation. Patients with HRS who fail to respond to medical therapy or those with severe renal failure of other etiology may require renal replacement therapy. Simultaneous liver kidney transplant (SLK) is needed in many of these patients to improve their post-transplant outcomes. However, the criteria to select patients who would benefit from SLK transplantation are based on consensus and lack strong evidence to support them. In this regard, novel serum and/or urinary biomarkers such as neutrophil gelatinase-associated lipocalin, interleukins-6 and 18, kidney injury molecule-1, fatty acid binding protein, and endothelin-1 are emerging with a potential for accurately differentiating common causes of AKI. Prospective studies are needed on the use of these biomarkers to predict accurately renal function recovery after liver transplantation alone in order to optimize personalized use of SLK.

    Stem cell therapy is emerging as a viable approach in regenerative medicine. A 31-year-old male with brachial plexus injury had complete sensory-motor loss since 16 years with right pseudo-meningocele at C5-D1 levels and extra-spinal extension up to C7-D1, with avulsion on magnetic resonance imaging and irreversible damage. We generated adipose tissue derived neuronal differentiated mesenchymal stem cells (N-AD-MSC) and bone marrow derived hematopoietic stem cells (HSC-BM). Neuronal stem cells expressed β-3 tubulin and glial fibrillary acid protein which was confirmed on immunofluorescence. On day 14, 2.8 ml stem cell inoculum was infused under local anesthesia in right brachial plexus sheath by brachial block technique under ultrasonography guidance with a 1.5-inch-long 23 gauge needle. Nucleated cell count was 2 × 10 4 /μl, CD34+ was 0.06%, and CD45-/90+ and CD45-/73+ were 41.63% and 20.36%, respectively. No untoward effects were noted. He has sustained recovery with re-innervation over a follow-up of 4 years documented on electromyography-nerve conduction velocity study. PMID:25116721

    Perioperative acute kidney injury (AKI) is a common, morbid, and costly surgical complication. Current efforts to understand and manage AKI in surgical patients focus on prevention, mitigation of further injury when AKI has occurred, treatment of associated conditions, and facilitation of renal recovery. Lesser severity AKI is now understood to be much more common, and more morbid, than was previously thought. The ability to detect AKI within hours of onset would be helpful in protecting the kidney and in preserving renal function, and several imaging and biomarker modalities are currently being evaluated.

    Background There is little information about the range of motion (ROM) and strength of the affected upper limbs of patients with permanent brachial plexus birth palsy. Patients and methods 107 patients who had brachial plexus surgery in Finland between 1971 and 1998 were investigated in this population-based, cross-sectional, 12-year follow-up study. During the follow-up, 59 patients underwent secondary procedures. ROM and isometric strength of the shoulders, elbows, wrists, and thumbs were measured. Ratios for ROM and strength between the affected and unaffected sides were calculated. Results 61 patients (57%) had no active shoulder external rotation (median 0° (-75–90)). Median active abduction was 90° (1–170). Shoulder external rotation strength of the affected side was diminished (median ratio 28% (0–83)). Active elbow extension deficiency was recorded in 82 patients (median 25° (5–80)). Elbow flexion strength of the affected side was uniformly impaired (median ratio 43% (0–79)). Median active extension of the wrist was 55° (-70–90). The median ratio of grip strength for the affected side vs. the unaffected side was 68% (0–121). Patients with total injury had poorer ROM and strength than those with C5–6 injury. Incongruity of the radiohumeral joint and avulsion were associated with poor strength values. Interpretation ROM and strength of affected upper limbs of patients with surgically treated brachial plexus birth palsy were reduced. Patients with avulsion injuries and/or consequent joint deformities fared worst. PMID:21142823

    Neurogenic bladder dysfunction due to spinal cord injury poses a significant threat to the well-being of patients. Incontinence, renal impairment, urinary tract infection, stones, and poor quality of life are some complications of this condition. The majority of patients will require management to ensure low pressure reservoir function of the bladder, complete emptying, and dryness. Management typically begins with anticholinergic medications and clean intermittent catheterization. Patients who fail this treatment because of inefficacy or intolerability are candidates for a spectrum of more invasive procedures. Endoscopic managements to relieve the bladder outlet resistance include sphincterotomy, botulinum toxin injection, and stent insertion. In contrast, patients with incompetent sphincters are candidates for transobturator tape insertion, sling surgery, or artificial sphincter implantation. Coordinated bladder emptying is possible with neuromodulation in selected patients. Bladder augmentation, usually with an intestinal segment, and urinary diversion are the last resort. Tissue engineering is promising in experimental settings; however, its role in clinical bladder management is still evolving. In this review, we summarize the current literature pertaining to the pathology and management of neurogenic bladder dysfunction in patients with spinal cord injury. PMID:26090342

    Purpose: To identify clinical and treatment-related predictors of brachial plexus-associated neuropathies after radiation therapy for head-and-neck cancer. Methods and Materials: Three hundred thirty patients who had previously completed radiation therapy for head-and-neck cancer were prospectively screened using a standardized instrument for symptoms of neuropathy thought to be related to brachial plexus injury. All patients were disease-free at the time of screening. The median time from completion of radiation therapy was 56 months (range, 6-135 months). One-hundred fifty-five patients (47%) were treated by definitive radiation therapy, and 175 (53%) were treated postoperatively. Radiation doses ranged from 50 to 74 Gy (median, 66 Gy). Intensity-modulated radiation therapy was used in 62% of cases, and 133 patients (40%) received concurrent chemotherapy. Results: Forty patients (12%) reported neuropathic symptoms, with the most common being ipsilateral pain (50%), numbness/tingling (40%), motor weakness, and/or muscle atrophy (25%). When patients with <5 years of follow-up were excluded, the rate of positive symptoms increased to 22%. On univariate analysis, the following factors were significantly associated with brachial plexus symptoms: prior neck dissection (p = 0.01), concurrent chemotherapy (p = 0.01), and radiation maximum dose (p < 0.001). Cox regression analysis confirmed that both neck dissection (p < 0.001) and radiation maximum dose (p < 0.001) were independently predictive of symptoms. Conclusion: The incidence of brachial plexus-associated neuropathies after radiation therapy for head-and-neck cancer may be underreported. In view of the dose-response relationship identified, limiting radiation dose to the brachial plexus should be considered when possible.

    A study of 10 patients with brachial plexus trauma was performed to determine whether the diagnostic accuracy of sensory evoked potentials (SEPs) may be improved by using stimulation of multiple peripheral nerves (median, radial, musculocutaneous and ulnar). In addition, the relative advantages of SEPs and peripheral electrophysiological studies were considered. SEP patterns following most common brachial plexus lesions were predictable. Injuries to the upper trunk affected the musculocutaneous and radial SEPs predominantly. Lower trunk or medial cord lesions primarily affected ulnar SEPs. Diffuse brachial plexus lesions affected SEPs from all stimulation sites. In the majority of cases, the necessary information was obtainable from conventional EMG: however, for lesions involving the upper segments only, SEP techniques were more useful. It is suggested that selective SEPs from appropriate peripheral nerves when interpreted in combination with conventional EMG may add useful additional information. PMID:6317804

    Aim: To compare retrocrural versus transaortic techniques for neurolytic celiac plexus block (NCPB) in patients suffering from upper abdominal malignancy. Methods: In this retrospective observational study between October 2013 and April 2015, 64 patients with inoperable upper abdominal malignancy received fluoroscopy-guided percutaneous NCPB in our institute. Their case files were reviewed and the patients were divided into two groups depending on the technique used to perform NCPB: retrocrural (Group R; n = 36) versus transaortic (Group T; n = 28). The primary outcome measure was pain as assessed with a numeric rating scale (NRS) from 0 to 10; the secondary outcome measures were morphine consumption per day (M), quality of life (QOL) as assessed by comparing the percent of positive responses in each group, and complications if any. These were noted and analyzed prior to intervention and then on day 1, weeks 1, 2, 3, and months 1, 2, 3, 6 following NCPB. Results: Patients in Group R had significantly reduced NRS pain scores at week 1, 2, 3, month 1 and 2 as compared to Group T (P < 0.05). Morphine consumption also reduced significantly in Group R at day 1, week 1, 2, and 3 (P < 0.05). QOL was found to be comparable between the groups, and no major complications were noted. Conclusion: Retrocrural NCPB provides superior pain relief along with a reduction in morphine consumption as compared to transaortic NCPB in patients with pain due to upper abdominal malignancy.

    We investigated the development of intracranial vascularization in the human fetus, with particular emphasis on the choroid plexus. The fetal brain was visualized in 102 patients with healthy pregnancies between 9 and 16 weeks' gestation. Imaging was done transvaginally except in the pregnancies of longer duration with unfavorable fetal positions. Color flow imaging was used to identify vessels in the cranium and within the choroid plexus. Pulsed Doppler signals were obtained from an internal carotid-middle cerebral artery and from a choroid plexus vessel. The pulsatility index was calculated from the Doppler spectral envelope. A major cerebral vessel could be seen at 9 weeks' gestation. Choroid plexus vessels were first seen at 10 weeks 3 days. Visualization rates ranged from 35 to 75% for plexus vessels, and 65 to 100% for cerebral vessels. Visualization of choroid plexus vessels was maximal at 13 weeks. The pulsatility index for the cerebral arteries at this gestational period averaged 2.6 +/- 0.6. The result for the choroid plexus was 1.66 +/- 0.5. (P < 0.001). Visualization of the vessels of the choroid plexus increases and decreases as the gland develops and shrinks. This developmental period also is the time of active neurogenesis. PMID:7837329

    Background Overlooked injuries and delayed diagnoses are still common problems in the treatment of polytrauma patients. Therefore, ongoing documentation describing the incidence rates of missed injuries, clinically significant missed injuries, contributing factors and outcome is necessary to improve the quality of trauma care. This review summarizes the available literature on missed injuries, focusing on overlooked muscoloskeletal injuries. Methods Manuscripts dealing with missed injuries after trauma were reviewed. The following search modules were selected in PubMed: Missed injuries, Delayed diagnoses, Trauma, Musculoskeletal injuires. Three time periods were differentiated: (n = 2, 1980–1990), (n = 6, 1990–2000), and (n = 9, 2000-Present). Results We found a wide spread distribution of missed injuries and delayed diagnoses incidence rates (1.3% to 39%). Approximately 15 to 22.3% of patients with missed injuries had clinically significant missed injuries. Furthermore, we observed a decrease of missed pelvic and hip injuries within the last decade. Conclusion The lack of standardized studies using comparable definitions for missed injuries and clinically significant missed injuries call for further investigations, which are necessary to produce more reliable data. Furthermore, improvements in diagnostic techniques (e.g. the use of multi-slice CT) may lead to a decreased incidence of missed pelvic injuries. Finally, the standardized tertiary trauma survey is vitally important in the detection of clinically significant missed injuries and should be included in trauma care. PMID:18721480

    The aim of this review is to discuss the basic forms of neuropsychological rehabilitation for patients with traumatic brain injury (TBI). More broadly, we discussed cognitive rehabilitation therapy (CRT) which constitutes a fundamental component in therapeutic interaction at many centres worldwide. Equally presented is a comprehensive model of rehabilitation, the fundamental component of which is CRT. It should be noted that the principles of this approach first arose in Poland in the 1970s, in other words, several decades before their appearance in other programmemes. Taken into consideration are four factors conditioning the effectiveness of such a process: comprehensiveness, earlier interaction, universality and its individualized character. A comprehensive programmeme of rehabilitation covers: cognitive rehabilitation, individual and group rehabilitation with the application of a therapeutic environment, specialist vocational rehabilitation, as well as family psychotherapy. These training programmemes are conducted within the scope of the 'Academy of Life,' which provides support for the patients in their efforts and shows them the means by which they can overcome existing difficulties. Equally emphasized is the close cooperation of the whole team of specialists, as well as the active participation of the family as an essential condition for the effectiveness of rehabilitation and, in effect, a return of the patient to a relatively normal life. Also presented are newly developing neurothechnologies and the neuromarkers of brain injuries. This enables a correct diagnosis to be made and, as a result, the selection of appropriate methods for neuropsychological rehabilitation, including neurotherapy. PMID:26094541

    The quality of life in patients with chronic pancreatitis (CP) is reduced due to their suffering of high levels of pain. It has been presented that quality of life can also be linked to religiosity and/or spirituality. The aim of this study is to assess the influence of religious practices on the quality of life and on the subjective level of pain in CP patients. Ninety-two patients (37 women and 55 men) with chronic pancreatitis were treated invasively for pain with neurolytic celiac plexus block (NCPB). The religiosity of the patients was recorded and served as a dichotomizer. Group 1 was for patients who claimed to have no contact with the church or to have very sporadic contact (N = 35 patients). Group 2 was for patients who claimed to have deep faith and were regular participants at church activities (N = 57 patients). Visual analogue scale was used to assess pain, while the quality of life was measured by using QLQ C-30 questionnaire adapted for chronic pancreatitis patients in Polish population. The patients were assessed prior to the pain-relieving intervention and subsequently 2 and 8 weeks after it. The intensity of pain was reduced in both groups significantly after performing the NCPB. Patients who declared a deep faith reported higher level of pain on the VAS scale prior to intervention than non-religious patients. Quality of life in both groups of patients significantly improved after NCPB. Following NCPB, global quality of life in patients who declared higher religiosity/church attendance was significantly higher (79.88) than for those patients who have no contact or sporadic contact with the church (44.21, P < 0.05). NCPB resulted in significant reduction of pain and increase in quality of life in both groups of patients with CP. Nevertheless, in the group declaring higher religiosity/church attendance, reported pain was higher, but, despite that, quality of life better. It may be concluded that religious practices might serve as an additional

    Whole body /sup 99m/T-pyrophosphate bone scans were obtained and correlated with skeletal radiographs for detection of heterotopic ossification in 135 spinal injury patients. There were 40 patients with recent injury (less than 6 months) and 95 with injury of over 6 months duration. Heterotopic new bone was detected on the bone scan in 33.7% of 95 patients with spinal cord injuries of more than 6 months duration and 30% of 40 patients with injuries of less than 6 months. The radionuclide scan was found to be useful in detection of heterotopic ossification at its early stage and in its differentiation from other complications in spinal cord injury patients.

    [Purpose] The objective of the study was to compare the incidence, diagnosis, treatment, and prognosis of patients with spinal cord stab injury to those with the more common spinal cord contusion injury. [Subjects] Of patients hospitalized in China Rehabilitation Research Center from 1994 to 2014, 40 of those having a spinal cord stab injury and 50 with spinal cord contusion were selected. [Methods] The data of all patients were analyzed retrospectively. The cases were evaluated by collecting admission and discharge ASIA (American Spinal Injury Association) and ADL (activity of daily living) scores. [Results] After a comprehensive rehabilitation program, ASIA and ADL scores of patients having both spinal cord stab injury and spinal cord contusion significantly increase. However, the increases were noted to be higher in patients having a spinal cord stab injury than those having spinal cord contusion. [Conclusion] Comprehensive rehabilitation is effective both for patients having spinal cord stab injury and those with spinal cord contusion injury. However, the prognosis of patients having spinal cord stab injury is better than that of patients with spinal cord contusion. PMID:26834329

    Although some patients have successful peripheral nerve regeneration, a poor recovery of hand function often occurs after peripheral nerve injury. It is believed that the capability of brain plasticity is crucial for the recovery of hand function. The supplementary motor area may play a key role in brain remodeling after peripheral nerve injury. In this study, we explored the activation mode of the supplementary motor area during a motor imagery task. We investigated the plasticity of the central nervous system after brachial plexus injury, using the motor imagery task. Results from functional magnetic resonance imaging showed that after brachial plexus injury, the motor imagery task for the affected limbs of the patients triggered no obvious activation of bilateral supplementary motor areas. This result indicates that it is difficult to excite the supplementary motor areas of brachial plexus injury patients during a motor imagery task, thereby impacting brain remodeling. Deactivation of the supplementary motor area is likely to be a serious problem for brachial plexus injury patients in terms of preparing, initiating and executing certain movements, which may be partly responsible for the unsatisfactory clinical recovery of hand function.

    Aims: We analyzed our series of patients with seatbelt signs (bruising) that underwent laparotomy in order to correlate injury pattern with clinical course and outcome. Materials and Methods: Retrospective analysis of patients with seatbelt signs presenting to the level 1 Trauma Unit between 2005 and 2010 was performed. We evaluated the nature of injuries during laparotomy associated with seatbelt signs and their treatment and complications. Results: There were 41 patients, 25 (61%) male, with a median age of 26 years. Median injury severity score (ISS) was 25 (range 6–66) and overall mortality was 10% (four patients). Patients were classified into three groups according to time from injury to surgery. Median time to surgery for the immediate group (n = 12) was 1.05 h, early group (n = 22) was 2.7 h, and delayed group (n = 7) was 19.5 h. Patients in the immediate group tended to have solid organ injuries; whereas, patients in the delayed group had bowel injury. Patients with solid organ injuries were found to be more seriously injured and had higher mortality (P < 0.01) and morbidity compared with patients with the “classic” bowel injury pattern associated with a typical seatbelt sign. Conclusion: Our data suggest that there is a cohort of patients with seatbelt injury who have solid organ injury requiring urgent intervention. Solid organ injuries associated with malpositioned seatbelts lying higher on the abdomen tend to result in hemodynamic instability necessitating immediate surgery. They have more postoperative complications and a greater mortality. Seatbelt signs should be accurately documented after any car crash. PMID:25400391

    Major trauma centres provide specialised care for patients who have experienced serious traumatic injury. This article provides information about major trauma centres and outlines the assessment tools used in this setting. Since patients in major trauma centres will be transferred to other settings, including inpatient wards and primary care, this article is relevant for both nurses working in major trauma centres and in these areas. Traumatic injuries require rapid assessment to ensure the patient receives prompt, adequate and appropriate treatment. A range of assessment tools are available to assist nurses in major trauma centres and emergency care to assess the severity of a patient's injury. The most commonly used tools are triage, Catastrophic Haemorrhage Airway to Exposure assessment, pain assessment and the Glasgow Coma Scale. This article summarises the use of these assessment tools in these settings, and discusses the use of the Injury Severity Score (ISS) to determine the severity of patient injuries. PMID:27484568

    The transplantation of embryonic stem cells can effectively improve the creeping strength of nerves near an injury site in animals. Amniotic epithelial cells have similar biological properties as embryonic stem cells; therefore, we hypothesized that transplantation of amniotic epithelial cells can repair peripheral nerve injury and recover the creeping strength of the brachial plexus nerve. In the present study, a brachial plexus injury model was established in rabbits using the C6 root avulsion method. A suspension of human amniotic epithelial cells was repeatedly injected over an area 4.0 mm lateral to the cephal and caudal ends of the C6 brachial plexus injury site (1 × 106 cells/mL, 3 μL/injection, 25 injections) immediately after the injury. The results showed that the decrease in stress and increase in strain at 7,200 seconds in the injured rabbit C6 brachial plexus nerve were mitigated by the cell transplantation, restoring the viscoelastic stress relaxation and creep properties of the brachial plexus nerve. The forepaw functions were also significantly improved at 26 weeks after injury. These data indicate that transplantation of human amniotic epithelial cells can effectively restore the mechanical properties of the brachial plexus nerve after injury in rabbits and that viscoelasticity may be an important index for the evaluation of brachial plexus injury in animals.

    Avulsion of the brachial plexus was documented in a Great Horned Owl (Bubo virginianus). A fractured scapula was also present. Cause of these injuries was not known but was thought to be due to trauma. Differentiation of musculoskeletal injury from peripheral nerve damage can be difficult in raptors. Use of electromyography and motor nerve conduction velocity was helpful in demonstrating peripheral nerve involvement. A brachial plexus avulsion was suspected on the basis of clinical signs, presence of electromyographic abnormalities in all muscles supplied by the nerves of the brachial plexus and absence of median-ulnar motor nerve conduction velocities.

    This study aimed to evaluate whether placing dose constraints on the brachial plexus (BP) could provide dosimetric benefits in patients with nasopharyngeal carcinoma (NPC) undergoing intensity-modulated radiation therapy (IMRT). Planning CT images for 30 patients with NPC treated with definitive IMRT were retrospectively reviewed. Target volumes, the BP and other critical structures were delineated; two separate IMRT plans were designed for each patient: one set no restrictions for the BP; the other considered the BP as a critical structure for which a maximum dose limit of ≤66 Gy was set. No significant differences between the two plans were observed in the conformity index, homogeneity index, maximum dose to the planning target volumes (PTVs), minimum dose to the PTVs, percentages of the volume of the PTVnx and PTVnd receiving more than 110% of the prescribed dose, or percentages of the volume of the PTVs receiving 95% and > 93% of the prescribed dose. Dose constraints significantly reduced the maximum dose, mean dose, V45, V50, V54, V60, V66 and V70 to the BP. Dose constraints significantly reduced the maximum dose to the BP, V45, V60 and V66 in both N0–1 and N2–3 disease; however, the magnitude of the dosimetric gain for each parameter between N0–1 and N2–3 disease was not significantly different, except for the V60 and V66. In conclusion, placing dose constraints on the BP can significantly decrease the irradiated volume and dose, without compromising adequate dose delivery to the target volume. PMID:25173085

    Purpose. To determine the efficacy of celiac plexus block during thermoablation of liver metastases. Methods. Fifty-five consecutive patients underwent thermoablation therapy of liver tumors by laser-induced thermotherapy. Twenty-nine patients received a temporary celiac plexus block, 26 patients acted as control group. In both groups fentanyl and midazolam were administered intravenously upon request of the patient. The duration of the intervention, consumption of opiates, and individual pain sensations were documented. Results. No complications resulting from the celiac plexus block were recorded. Celiac plexus block significantly reduced the amount of pain medication used during thermoablation therapy of liver tumors (with block, 2.45 {mu}g fentanyl per kg body weight; without block, 3.58 {mu}g fentanyl per kg body weight, p < 0.05; midazolam consumption was not reduced) in patients with metastases {<=}5 mm from the liver capsule. For metastases farther away from the capsule no significant differences in opiate consumption were seen. Celiac plexus block reduced the time for thermoablation significantly (178 min versus 147 min, p < 0.05) no matter how far the metastases were from the liver capsule. Average time needed to set the block was 12 min (range 9-15 min); additional costs for the block were marginal. As expected (as pain medications were given according to individual patients' needs) pain indices did not differ significantly between the two groups. Conclusion. In patients with liver metastases {<=}5 mm from the liver capsule, celiac plexus block reduces the amount of opiates necessary, simplifying patient monitoring. In addition celiac plexus block reduces intervention time, with positive effects on overall workflow for all patients.

    High-energy pelvic ring injuries can represent life-threatening injuries in the polytraumatized patient, particularly when presenting with hemodynamic instability. These injuries mandate a systematic multidisciplinary approach to evaluation, and timely intervention to address hemorrhage while concomitantly addressing mechanical instability. These pelvic injuries are associated with potentially lethal hemorrhage originating from venous, arterial, and osseous sources. A thorough understanding of anatomy, radiographic findings, and initial physical examination can alert one to the presence of pelvic instability necessitating emergent treatment. The focus is on hemorrhage control, using techniques for skeletal stabilization, angiography, and open procedures to decrease mortality in this high-risk patient population. PMID:27241378

    Abstract Little is known about injury of the arcuate fasciculus (AF) in patients with mild traumatic brain injury (TBI). We investigated injury of the AF in the dominant hemisphere in patients with mild TBI, using diffusion tensor tractography (DTT). We recruited 25 patients with injury of the left AF among 64 right-handed consecutive patients with mild TBI and 20 normal control subjects. DTTs of the left AF were reconstructed, and fractional anisotropy (FA), apparent diffusion coefficient (ADC), and fiber number of the AF were measured. Among 64 consecutive patients, 25 (39%) patients showed injury of the left AF. The patient group showed lower FA value and fiber number with higher ADC value than the control group (P < 0.05). On K-WAB evaluation, aphasia quotient and language quotient were 95.9 ± 4.1 (range 85–100) and 95.0 ± 5.4 (range 80–100), respectively. However, 23 (92.0%) of 25 patients complained of language-related symptoms after TBI; paraphasia in 12 (48.0%) patients, deficits of comprehension in 4 (16.0%) patients, deficits of speech production in 1 (4.0%) patient, and >2 language symptoms in 6 (24.0%) patients. We found that a significant number (39%) of patients with mild TBI had injury of the AF in the dominant hemisphere and these patients had mild language deficit. These results suggest that DTT could provide useful information in detecting injury of the AF and evaluation of the AF using DTT would be necessary even in the case of a patient with mild TBI who complains of mild language deficit.

    Chronic pelvic pain is a common problem with variable etiology. The sympathetic nervous system plays an important role in the transmission of visceral pain regardless of its etiology. Sympathetic nerve block is effective and safe for treatment of pelvic visceral pain. One of them, the inferior hypogastric plexus, is not easily assessable to blockade by local anesthetics and neurolytic agents. Inferior hypogastric plexus block is not commonly used in chronic pelvic pain patients due to pre-sacral location. Therefore, inferior hypogastric plexus is not readily blocked using paravertebral or transdiscal approaches. There is only one report of inferior hypogastric plexus block via transsacral approach. This approach has several disadvantages. In this case a favorable outcome was obtained by using coccygeal transverse approach of inferior hypogastric plexus. Thus, we report a patient who was successfully given inferior hypogastric plexus block via coccygeal transverse approach to treat chronic pelvic pain conditions involving the lower pelvic viscera.

    Our goal was to evaluate brachial plexus (BP) dose with and without the use of supraclavicular (SCL) irradiation in patients undergoing breast-conserving therapy with whole-breast radiation therapy (RT) after lumpectomy. Using the standardized Radiation Therapy Oncology Group (RTOG)-endorsed guidelines delineation, we contoured the BP for 10 postlumpectomy breast cancer patients. The radiation dose to the whole breast was 50.4 Gy using tangential fields in 1.8-Gy fractions, followed by a conedown to the operative bed using electrons (10 Gy). The prescription dose to the SCL field was 50.4 Gy, delivered to 3-cm depth. The mean BP volume was 14.5 {+-} 1.5 cm{sup 3}. With tangential fields alone, the median mean dose to the BP was 0.57 Gy, the median maximum dose was 1.93 Gy, and the irradiated volume of the BP receiving 40, 45, and 50 Gy was 0%. When the third (SCL field) was added, the dose to the BP was significantly increased (P = .01): the median mean dose to the BP was 40.60 Gy, and the median maximum dose was 52.22 Gy. With 3-field RT, the median irradiated volume of the BP receiving 40, 45, and 50 Gy was 83.5%, 68.5%, and 24.6%, respectively. The addition of the SCL field significantly increases dose to the BP. The possibility of increasing the risk of BP morbidity should be considered in the context of clinical decision making.

    Coated-platelets are procoagulant platelets that are elevated in stroke and are associated with stroke recurrence. In a previous study, prompted by data showing an increased risk for stroke following traumatic brain injury (TBI), we found that coated-platelet levels are elevated in patients with combat-related mild TBI (mTBI) several years after the injury, compared with controls. We now investigate in an expanded patient population whether parameters commonly recorded in mTBI are related to increased coated-platelet potential. Coated-platelet levels were assayed in 120 mTBI patients at intervals ranging from 6 months to 10 years from the last injury. Correlations were calculated between coated-platelet levels and age, gender, race/ethnicity, loss of consciousness, alteration in consciousness, post-traumatic amnesia, number of injuries, mechanism of injury, time since first and last injury, smoking, medications that may influence coated-platelet levels, and pertinent comorbid conditions. Significant correlations were detected between coated-platelet levels and number of injuries (p = 0.026), gender (p = 0.01), and time since last injury (p = 0.04). A multi-variable linear model analysis, including these three parameters and an additional three parameters (race/ethnicity, smoking, and mechanism of injury) that reached a p value of <0.2, showed that the number of injuries were predictive of coated-platelet levels (p = 0.004). These results support a mechanistic link between increased coated-platelet levels and repeated injuries in mTBI. Long-term studies will be required to determine the impact of increased prothrombotic potential in mTBI patients. PMID:26414016

    The target rate for trauma undertriage is <5 per cent, but rates are as high as 30 to 40 per cent in many trauma systems. We hypothesized that high undertriage rates were due to the tendency to undertriage injured elderly patients and a growing elderly population. We conducted a retrospective analysis of all hospital visits in California using the Office of Statewide Health Planning and Development Database over a 5-year period. All hospital admissions and emergency department visits associated with injury were longitudinally linked. The primary outcome was triage pattern. Triage patterns were stratified across three dimensions: age, mechanism of injury, and access to care. A total of 60,182 severely injured patients were included in the analysis. Fall-related injuries were frequently undertriaged compared with injuries from motor vehicle collisions (MVCs) and penetrating trauma (52% vs 12% and 10%, respectively). This pattern was true for all age groups. Conversely, MVCs and penetrating traumas were associated with high rates of overtriage (>70% for both). In conclusion, in contrast to our hypothesis, we found that triage is largely determined by mechanism of injury regardless of injury severity. High rates of undertriage are largely due to the undertriage of fall-related injuries, which occurs in both younger and older adults. Patients injured after MVCs and penetrating trauma victims are brought to trauma centers regardless of injury severity, resulting in high rates of overtriage. These findings suggest an opportunity to improve trauma system performance. PMID:27097630

    2016-01-01

    The study of the structures that make up the brachial plexus has benefited particularly from the high resolution images provided by 3T magnetic resonance scanners. The brachial plexus can have mononeuropathies or polyneuropathies. The mononeuropathies include traumatic injuries and trapping, such as occurs in thoracic outlet syndrome due to cervical ribs, prominent transverse apophyses, or tumors. The polyneuropathies include inflammatory processes, in particular chronic inflammatory demyelinating polyneuropathy, Parsonage-Turner syndrome, granulomatous diseases, and radiation neuropathy. Vascular processes affecting the brachial plexus include diabetic polyneuropathy and the vasculitides. This article reviews the anatomy of the brachial plexus and describes the technique for magnetic resonance neurography and the most common pathologic conditions that can affect the brachial plexus.

    We reviewed records of adult patients admitted to our burn unit who were reported to abuse drugs or alcohol from 1985 to 1988. The proportion of patients reported as abusing drugs increased significantly from 1987 to 1988, compared to previous years. However, there was no increase in the proportion of patients reported to abuse alcohol. Patients identified as abusing drugs had longer hospital stays, compared to patients who were not reported to abuse substances. Methamphetamine and cocaine were the drugs most often abused by patients who abused drugs or both drugs and alcohol. Mechanisms of burn injury in these patients included "accidental" burn injury related to acute intoxication, and self-injury due to psychosis or depression. PMID:1882020

    Brachial plexus palsy affects children differently than adults. In children with obstetric brachial plexus palsy, motor development must depend on nervous system adaptation. Previous studies report sensory plasticity in these children. This noninvasive study provides support for neural plasticity (the general ability of the brain to reorganize neural pathways based on new experiences) in children with obstetric brachial plexus palsy by considering upper limb preference. As in the general population, we expect that 90% of children would prefer their right upper limb. However, only 17% of children affected by right obstetric brachial plexus palsy prefer the right upper limb for overall movement; children with left obstetric brachial plexus palsy did not significantly differ from the general population in upper limb preference. This study also provides the first evidence of a significant correlation between actual task performance and select obstetric brachial plexus palsy outcome measurement systems, thereby justifying the routine use of these outcome measurement systems as a reflection of the practical utility of the affected limb to the patient.

    The association of choroid plexus cysts with fetal aneuploidy, particularly trisomy 18, was first noted in 1986. Through the years there have been numerous reports on this subject, but no consensus has been reached with regard to chromosomal risk. In this review, we attempt to summarise published reports on second trimester choroid plexus cysts, with an emphasis on the strengths and weaknesses of each report. Based on these reports, additional malformations are a significant risk factor for aneuploidy and an indication for determination of fetal karyotype. The management of isolated choroid plexus cysts remains controversial. PMID:9678699

    Objective To analyze anatomical variations associated with celiac plexus complex by means of computed tomography simulation, assessing the risk for organ injury as the transcrural technique is utilized. Materials and Methods One hundred eight transaxial computed tomography images of abdomen were analyzed. The aortic-vertebral, celiac trunk (CeT)-vertebral, CeT-aortic and celiac-aortic-vertebral topographical relationships were recorded. Two needle insertion pathways were drawn on each of the images, at right and left, 9 cm and 4.5 cm away from the midline. Transfixed vital organs and gender-related associations were recorded. Results Aortic-vertebral - 45.37% at left and 54.62% in the middle; CeT-vertebral - T12, 36.11%; T12-L1, 32.4%; L1, 27.77%; T11-T12, 2.77%; CeT-aortic - 53.7% at left and 46.3% in the middle; celiac-aortic-vertebral - L-l, 22.22%; M-m, 23.15%; L-m, 31.48%; M-l, 23.15%. Neither correspondence on the right side nor significant gender-related associations were observed. Conclusion Considering the wide range of abdominal anatomical variations and the characteristics of needle insertion pathways, celiac plexus block should not be standardized. Imaging should be performed prior to the procedure in order to reduce the risks for injuries or for negative outcomes to patients. Gender-related anatomical variations involved in celiac plexus block should be more deeply investigated, since few studies have addressed the subject. PMID:25741102

    Background We wanted to investigate acetabular labral tears and their correlation with femoroacetabular impingement in patients with sports injury. Methods Among 111 patients who were diagnosed with the acetabular labral tears after arthroscopic treatment from January 2004 to December 2007, we selected 41 patients with sports injury. There were 12 cases of Taekwondo injury, 5 of golf injury, 4 of soccer injury, 3 of gymnastics injury, 2 of Hapkido injury, 2 of aerobics injury, 2 of rock-climbing injury, 2 of fitness training injury and 9 of other sports injuries. We checked the subtypes of acetabular labral tears and the accompanying femoroacetabular impingement. For the cases with accompanying femoroacetabular impingement, we investigated the subtypes according to the types of sports, gender and age. At last follow-up, we checked the Harris Hip Score (HHS), the Hip Outcome Score (HOS) sports scale and the percentage of patients who returned to their sports activity. Results The average age of symptomatic onset was 26 years (range, 12 to 65 years). The ratio of males to females was 29 : 12. An average duration of the hip pain was 17 months (range, 1 to 60 months). The degenerative type of acetabular labral tears was the most prevalent with 32 cases (78%), and there were 9 cases (22%) of the partial tear type. Thirty cases (73%) were accompanied by femoroacetabular impingement. The average age of the 23 cases (56%) of the cam-type was 23 years (range, 12 to 48 years), and it was more likely to occur in men (87%) and for people practicing martial arts such as Taekwondo or Hapkido. An average age of the 5 cases (12%) of the pincer-type was 26 (range, 16 to 43 years), it usually occurred in women (60%) and for non-martial arts such as golf and gymnastics. There were 2 cases of the mixed type (cam + pincer-type). At 27 months follow-up, the HHS was 61 to 92 points, the HOS sports scale increased 43 to 75%, and the rate of returning to sports was 71%.

    Data of 98 patients who had sustained traumatic injuries to the duodenum during a recent 7-year period is reviewed. The overall mortality was 23.5%; that of the blunt injury group was 35%, that of the penetrating injury group was 20%. However, after the establishment of a trauma unit, the mortality for duodenal injuries fell from 32% to 12%. Death from duodenal wounds may be reduced by earlier hospitalization, earlier diagnosis and consequently earlier surgical repair. Vigorous treatment of shock is essential. A specialized trauma unit with personnel experienced in the management of shock and trauma problems provides a better environment to carry out the preoperative and postoperative care of the acutely injured patient. Adequate surgical treatment of the blunt injury and missile injury of the duodenum should consist of the following procedures: 1) repair of the duodenal wall utilizing conventional techniques; 2) internal decompression of the repair by afferent jejunostomy; 3) efferent jejunostomy for postoperative feeding; 4) temporary gastrostomy; and 5) external drainage of the repair. In certain selected instances, the simple stab wound of the duodenum may be treated by conventional repair without decompression, but a loop of jujunum should be sutured over the repair to prevent delayed disruption. The majority of patients with injuries to the duodenum have associated organs injured which also require considered surgical judgment and action. PMID:1119875

    Amyothropic neuralgy is a rare disease witch unknown etiopathogenesis. The main popular theory says that inflammatory and immunomodulatory process is connected with that disease. Diagnosis is made after exclusion of other causes of plexus lumbosacralis damage. The main symptom is neuropathic pain after which there is observed muscle weakness and atrophy. ENG/EMG study and MRI are made to confirm the diagnosis. In this study we described a case of 52 years old female with lower limbs paresis, who was diagnosed few years after first symptoms. Limb paresis was preluded by lumbar pain. MRI study revealed central spinal disc herniations on L1-2, L2-3, L3-4 levels with dura matter compression, L4-5 spinal disc right lateral herniation and synovial cyst. MRI of both lumbar plexuses was also normal. EMG study revealed features of bilateral, chronic damage of lower legs nerves on lumbar plexus level. Patient was treated with physiotherapy and gabapentin with dose of 2x600mg per day. PMID:25771520

    2012-01-01

    Background Purpose of the presented study is to answer the following questions: Are knee injuries associated with trauma mechanisms or concomitant injuries? Do injuries of the knee region aggravate treatment costs or prolong hospital stay in polytraumatized patients? Methods A retrospective analysis including 29.779 severely injured patients (Injury Severity Score [greater than or equal to] 16) from the Trauma Registry of the German Society for Trauma Surgery database (1993-2008) was conducted. Patients were subdivided into two groups; the "Knee" group (n=3.458, 11.6% of all patients) including all multiple trauma patients with knee injuries, and the "Non Knee" group (n=26.321) including the remaining patients. Patients with knee injuries were slightly younger, less often male gender and had a significantly increased ISS. Results Patients in the Knee group suffered significantly more traffic accidents compared to the Non Knee group (82% vs. 52%, p<0.001). These injuries were more often caused by car or motorbike accidents. Severe thoracic and limb injuries (AIS[greater than or equal to]3) were more frequently found in the Knee group (p<0.001) while head injury was distributed equally. The overall hospital stay, ICU stay, and treatment costs were significantly higher for the Knee group (38.1 vs. 25.5 days, 15.2 vs. 11.4 days, 40,116 vs. 25,336 Euro, respectively; all p<0.001). Conclusions Traffic accidents are associated with an increased incidence of knee injuries than falls or attempted suicides. Furthermore, severe injuries of the limbs and chest are more common in polytraumatized patients with knee injuries. At last, treatment of these patients is prolonged and consequently more expensive.

    Uncommon tumefactions known as xanthogranulomas can occur throughout the body. Some appear to develop as benign or malignant neoplasms. An even less familiar xanthogranuloma occurs within the choroid plexus. Most are tiny plaques only a few millimeters in diameter. However, they can present as masses of significant size within the glomus. When large and unilateral, they are included in the differential diagnosis of choroid plexus tumors. A computed tomographic (CT) study of such a tumor is presented.

    Purpose: To identify volume and dose predictors of paresthesia after irradiation of the brachial plexus among women treated for breast cancer. Methods and Materials: The women had breast surgery with axillary dissection, followed by radiation therapy with (n=192) or without irradiation (n=509) of the supraclavicular lymph nodes (SCLNs). The breast area was treated to 50 Gy in 2.0-Gy fractions, and 192 of the women also had 46 to 50 Gy to the SCLNs. We delineated the brachial plexus on 3-dimensional dose-planning computerized tomography. Three to eight years after radiation therapy the women answered a questionnaire. Irradiated volumes and doses were calculated and related to the occurrence of paresthesia in the hand. Results: After treatment with axillary dissection with radiation therapy to the SCLNs 20% of the women reported paresthesia, compared with 13% after axillary dissection without radiation therapy, resulting in a relative risk (RR) of 1.47 (95% confidence interval [CI] 1.02-2.11). Paresthesia was reported by 25% after radiation therapy to the SCLNs with a V{sub 40} {sub Gy} ≥ 13.5 cm{sup 3}, compared with 13% without radiation therapy, RR 1.83 (95% CI 1.13-2.95). Women having a maximum dose to the brachial plexus of ≥55.0 Gy had a 25% occurrence of paresthesia, with RR 1.86 (95% CI 0.68-5.07, not significant). Conclusion: Our results indicate that there is a correlation between larger irradiated volumes of the brachial plexus and an increased risk of reported paresthesia among women treated for breast cancer.

    The technetium /sup 99m/Tc sulfur colloid liver-spleen scan is a valuable aid in diagnosis and treatment of patients with splenic injury. After reviewing the charts of 47 patients who were ill as a result of splenic trauma, we came to the following conclusions: (1) the scan identified the injury, accurately mapped its extent, and indicated the presence or absence of associated liver injuries; (2) the scans were useful in following the extent and rate of healing of the splenic injury; (3) the scan is an indirect measurement of of return of splenic fuction; (4) the procedure can be performed in a reasonable time frame with no serious morbidity; and (5) the indications, contraindications, and timing of scans are now reasonably well established.

    We reviewed 64 patients with perforation or full-thickness injury of the alimentary tract after acid ingestion. Based on our classification of laparotomy findings, there were class I (n = 15); class II (n = 13); class III (n = 16); and class IV (n = 20). Study parameters were preoperative laboratory data, gastric perforation, associated visceral injury, and extension of the injury. End points of the study were the patients' mortality and length of hospital stay. All these patients underwent esophagogastrectomy with (n = 16) or without (n = 24) concomitant resection, esophagogastroduodenojejunectomy with (n = 4) or without (n = 13) concomitant resection, and laparotomy only (n = 7). Concomitant resections were performed on the spleen (n = 10), colon (n = 2), pancreas (n = 1), gall bladder (n = 1), skipped areas of jejunum (n = 4), and the first portion of the duodenum (n = 4). The study demonstrates five preoperative risk factors, female gender, shock status, shock index, pH value, and base deficit, and four intraoperative risk factors, gastric perforation, associated visceral injury, injury beyond the pylorus, and continuous involvement of the jejunum over a length of 50 cm. The overall mortality rate was 45.3%, which increased significantly with advancing class of corrosive injury. PMID:26582190

    Background: Reports on outcome after posterior cruciate ligament (PCL) reconstruction often contain both isolated PCL and combined knee ligament injuries. This makes it difficult to conclude on the outcome after reconstruction of isolated PCL injuries. Purpose: To investigate the outcome after PCL reconstruction in patients with an isolated PCL injury and to compare this with the outcome of patients treated with reconstruction after isolated anterior cruciate ligament (ACL) injuries. Study Design: Cohort study; Level of evidence, 3. Methods: Seventy-one patients with an isolated PCL injury that was reconstructed surgically and who had registered in the Norwegian Knee Ligament Registry between 2004 and 2010 were included in this study. Patients with isolated ACL reconstructions (n = 9661) who had registered in the same period were included for comparison. Knee Injury and Osteoarthritis Outcome Score (KOOS) was used as the patient-reported outcome measure. Preoperative and 2-year postoperative KOOS scores were compared. Changes in KOOS score reported by the PCL patients were compared with changes reported by the ACL patients. Results: At the 2-year postoperative follow-up of the PCL-reconstructed patients, the patient-reported outcome was improved, measured by KOOS as follows: pain, 15.1 (95% CI, 8.5-21.8; P < .001); symptoms, 0.9 (95% CI, –6.6 to 8.3; P = .82); activities of daily living, 13.2 (95% CI, 6.6-13.9; P < .001); sports, 20.7 (95% CI, 11.8-29.4; P < .001); and quality of life, 26.6 (95% CI, 18.9-34.2; P < .001). According to the KOOS, the incremental improvements were similar for PCL and ACL patients. Time from injury to surgery was longer for the PCL patients compared with ACL patients (median, 21.5 vs 8.0 months; P < .001). Conclusion: Patients undergoing PCL reconstruction can expect the same improvements in KOOS score as patients undergoing ACL reconstruction. However, PCL patients start out with an inferior score on average and consequently end up

    Brachial plexus injury has often occurred secondary to malposition of the patient during general anesthesia. We have experienced median nerve injury following laparoscopic sigmoidectomy. A 61-year-old man with diabetes and hypertension received laparoscopic sigmoidectomy under general and epidural anesthesia. Tracheal intubation was easy without excessive retroflextion of his neck after anesthesia induction with fentanyl, propofol, and vecuronium. Both his upper arms were abducted to 80 degrees and his elbows were extended on a padded arm board. The shoulder braces were placed over both his acromioclavicular joints. His head remained in neutral position. Anesthesia was maintained with air, oxygen, sevoflurane, fentanyl, and vecuronium using mepivacaine via epidural catheter. During surgical procedures, he was in a combined lithotomy and head down position at maximum of 20 degrees. The operative table was tilted to the right at maximum of 20 degrees. The operation was finished successfully in 2 hours and 40 minutes without a special event. Postoperatively, he complained of numbness of the first, second, and third digits, and the radial side of fourth digit in his right hand. The redness on both his shoulders was observed. Muscle weakness and motor disturbance were not observed. Orthopedic surgeon diagnosed him as right median nerve injury. His symptoms improved gradually by physical training and disappeared one week after the operation. We suspect that his right median nerve injury was caused by compression and stretching of the brachial plexus in head down position, right lateral tilt table, use of shoulder brace, laparoscopy, abduction of the upper arm, and extension of the elbow. In laparoscopic operation in head down position, we should avoid using the shoulder brace to minimize the risk of brachial plexus injury. The arms should be approximated to the sides as nearly as possible and the elbows should be gently flexed to unload the median nerve and relieve

The patients were a 38-year-old woman with a history of breast cancer 6 years earlier whose computed tomography (CT) scans revealed a mass lesion at the infraclavicular part of the right brachial plexus, a 68-year-old man diagnosed with advanced lung cancer whose CT scans revealed a bone metastasis in the right humerus invading the axillary region of the right brachial plexus, and a 67-year-old woman diagnosed with advanced lung cancer whose CT scans revealed a bone metastasis in the left humerus invading the axillary region of the left brachial plexus. Ultrasound-guided pulsed RF was performed within the interscalene brachial plexus. During the follow-up period, their intractable pain was moderately controlled. PMID:23070568

    PubMed Central

    2015-01-01

    Traumatic brain injury (TBI) is usually combined with cervical spine (C-spine) injury. The possibility of C-spine injury is always considered when performing endotracheal intubation in these patients. Rapid sequence intubation is recommended with adequate sedative or analgesics and a muscle relaxant to prevent an increase in intracranial pressure during intubation in TBI patients. Normocapnia and mild hyperoxemia should be maintained to prevent secondary brain injury. The manual-in-line-stabilization (MILS) technique effectively lessens C-spine movement during intubation. However, the MILS technique can reduce mouth opening and lead to a poor laryngoscopic view. The newly introduced video laryngoscope can manage these problems. The AirWay Scope® (AWS) and AirTraq laryngoscope decreased the extension movement of C-spines at the occiput-C1 and C2-C4 levels, improving intubation conditions and shortening the time to complete tracheal intubation compared with a direct laryngoscope. The Glidescope® also decreased cervical movement in the C2-C5 levels during intubation and improved vocal cord visualization, but a longer duration was required to complete intubation compared with other devices. A lightwand also reduced cervical motion across all segments. A fiberoptic bronchoscope-guided nasal intubation is the best method to reduce cervical movement, but a skilled operator is required. In conclusion, a video laryngoscope assists airway management in TBI patients with C-spine injury. PMID:26045922

    Sepsis and septic shock are life threatening condition associated with high mortality rate in critically-ill patients. This high mortality is mainly related to the inadequacy between oxygen delivery and cellular demand leading to the onset of multiorgan dysfunction. Whether this multiorgan failure affect the pancreas is not fully investigated. In fact, pancreatic injury may occur because of ischemia, overwhelming inflammatory response, oxidative stress, cellular apoptosis and/or metabolic derangement. Increased serum amylase and/or lipase levels are common in patients with septic shock. However, imaging test rarely reveal significant pancreatic damage. Whether pancreatic dysfunction does affect the prognosis of patients with septic shock or not is still a matter of debate. In fact, only few studies with limited sample size assessed the clinical relevance of the pancreatic injury in this group of patients. In this review, we aimed to describe the epidemiology and the physiopathology of pancreatic injury in septic shock patients, to clarify whether it requires specific management and to assess its prognostic value. Our main finding is that pancreatic injury does not significantly affect the outcome in septic shock patients. Hence, increased serum pancreatic enzymes without clinical features of acute pancreatitis do not require further imaging investigations and specific therapeutic intervention. PMID:27559431

    The therapeutic concept of limb salvage or immediate amputation is controversial in patients with multiple trauma. Sixty-three multiple trauma patients (injury severity score ISS > 18 patients) with blunt arterial injuries were investigated. Twenty-seven had injuries of the upper limb and 36 patients of the lower limb. In 33 cases a limb salvage procedure was performed (group I), while in 30 cases the limb was amputated (group II). Neither group showed a significant difference in age (I: 33 +/- 3, II: 30 +/- 3 years), ISS (I: 30 +/- 2, II: 29 +/- 2 patients), time of ischemia (I: 238 +/- 30, II: 203 +/- 20 min) ICU stay (I: 18 +/- 4, II: 19 +/- 4 days). Lethality and morbidity were slightly increased in group I (death: I: n = 8; II: n = 4; MOF: I: n = 5; II: n = 3; Sepsis: I: n = 11, II: n = 4). No differences were found in the incidence of local infections (I: n = 12, II: n = 10). Secondary amputations were performed in 7 patients after 12 +/- 2 days (range 3-40; median: 5 days). We conclude that limb salvage did not increase the risk for severe complications. Lethality and morbidity were related to the severity of the injury. To prevent complications, secondary amputations had to be performed early. PMID:8975376

    Methylprednisolone sodium succinate (MPSS) for treatment of acute spinal cord injury (SCI) has been associated with both benefits and adverse events. MPSS administration was the standard of care for acute SCI until recently when its use has become controversial. Patients with SCI have had little input in the debate, thus we sought to learn their opinions regarding administration of MPSS. A summary of the published literature to date on MPSS use for acute SCI was created and adjudicated by 28 SCI experts. This summary was then emailed to 384 chronic SCI patients along with a survey that interrogated the patients' neurological deficits, communication with physicians and their views on MPSS administration. 77 out of 384 patients completed the survey. 28 respondents indicated being able to speak early after injury and of these 24 reported arriving at the hospital within 8 hours of injury. One recalled a physician speaking to them about MPSS and one patient reported choosing whether or not to receive MPSS. 59.4% felt that the small neurological benefits associated with MPSS were 'very important' to them (p<0.0001). Patients had 'little concern' for potential side-effects of MPSS (p = 0.001). Only 1.4% felt that MPSS should not be given to SCI patients regardless of degree of injury (p<0.0001). This is the first study to report SCI patients' preferences regarding MPSS treatment for acute SCI. Patients favor the administration of MPSS for acute SCI, however few had input into whether or not it was administered. Conscious patients should be given greater opportunity to decide their treatment. These results also provide some guidance regarding MPSS administration in patients unable to communicate.

    Proper nutrition is critical for recovery from traumatic brain injury (TBI). Prompt enteral feeding of moderate to severe TBI patients has been associated with significantly lower mortality and rates of infection. Probiotic supplementation has been associated with significantly lower rates of infection in TBI and other trauma patients. Human studies have suggested that supplementation with omega 3 fats, vitamin D, N-Acetylcysteine, branched chain amino acids, and zinc may be helpful for recovery from TBI. Animal TBI models have suggested that alpha-lipoic acid, magnesium, taurine, coenzyme Q10, and many phytonutrients (such as resveratrol) are also helpful. Unfortunately, recent human clinical trials with citicoline in TBI and stroke patients have produced disappointing results. Much more research is needed on multifaceted nutritional strategies to treat TBI patients in both the immediate post-injury phase and throughout the patients lifespan. PMID:24844176

    Renal disease is a common complication of HIV-infected patients, associated with increased risk of cardiovascular events, progression to AIDS, AIDS-defining illness, and mortality. Early and accurate identification of renal disease is therefore crucial to improve patient outcomes. The use of serum creatinine, along with proteinuria, to detect renal involvement is essentially to screen for markers of glomerular disease and may not be effective in detecting earlier stages of renal injury. Therefore, more sensitive and specific markers are needed in order to early identify HIV-infected patients at risk of renal disease. This review article summarizes some new and important urinary markers of tubular injury in HIV-infected patients and their clinical usefulness in the renal safety follow-up of TDF-treated patients.

    Nerve enlargement has early been recognized in CIDP and plexus MRI hypertrophy has been reported in typical CIDP cases. Our aim is to determine plexus MRI value in the diagnosis of CIDP with an initial atypical presentation, which, up to now, has not been demonstrated. Retrospective study of 33 consecutive patients suspected of CIDP. Plexus MRI was performed on the most affected territory (brachial or lumbar). Were assessed: plexus trophicity, T2-STIR signal intensity and gadolinium enhancement. Final CIDP diagnosis was made after comprehensive workup. A histo-radiological correlation was performed. Final CIDP diagnosis was made in 25 (76%) including 21 with initial atypical clinical presentation. Eleven CIDP patients (52%) with initial atypical clinical presentation had abnormal plexus MRI including 9 suggestive of CIDP (43%) and none of the patients with an alternative diagnosis. Hypertrophy of the proximal plexus and/or extraforaminal roots was found in 8 cases and Gadolinium enhancement in 2 cases. Abnormalities were more frequent on brachial (86%) than lumbosacral MRIs (29%) and asymmetrical (72%) and most often associated with histological signs of demyelination. The nerve biopsy was suggestive of CIDP in 9/13 patients with normal MRI. Plexus MRI seems useful in the diagnostic strategy of patients with suspicion of CIDP with atypical presentation. Nerve biopsy remains important when other investigations are inconclusive. PMID:26723995

    Choroid plexus tumours are rare, with a peak incidence in the first two years of life. The most common location is the lateral ventricle in children, while in adults it is the fourth ventricle. The most common clinical manifestation is the signs and symptoms of intracranial hypertension. They are histologically classified as plexus papilloma, atypical plexus papilloma, and plexus carcinoma. A review is presented on choroid plexus tumours treated in the Hospital Sant Joan de Déu between 1980 and 2014. A total of 18 patients have been treated. An analysis was made of the demographic, clinical, histological data, treatment, and recurrences. The treatment of choice is complete resection, accompanied by adjuvant therapy in carcinomas. In atypical papillomas, the use of adjuvant therapies is controversial, reserving radiation therapy for recurrences. Papillomas have a good outcome, whereas atypical papillomas and carcinomas outcome is poor. PMID:26209253

    Myeloid sarcoma is a rare hematological disorder that presents as an extramedullary mass of immature myeloid precursors. We herein present the case of a 57-year-old man with a seven-month history of progressive weakness in the right upper extremity. Reconstruction magnetic resonance neurography showed a marked enlargement of the right brachial plexus. Fluorodeoxyglucose positron emission tomography revealed a radioactive lesion in the sacrum, in addition to the right brachial plexus, and a biopsy of the sacrum revealed myeloid sarcoma. The brachial plexus lesion was also regarded as myeloid sarcoma because of the treatment response. Isolated myeloid sarcoma involving the brachial plexus is very rare and its diagnosis is difficult as there was neither a history of leukemia nor bone marrow involvement in this patient. In this case, reconstructed magnetic resonance neurography was useful for detecting the brachial plexus mass lesion which led to an early diagnosis and good recovery. PMID:26328656

    Current literature has reported an increase in the rates of morbidity and mortality in elderly dementia patients who have suffered from illnesses such as pneumonia or traumatic injuries such as falls, motor vehicle collisions, and other insults. The role of dementia in elderly burn patients has not been studied in depth. To assess the extent of this problem, a retrospective, case-control study of patients with dementia who were admitted to a large urban burn center was performed. The demographics, circumstance and severity of injury, critical care use, and discharge disposition of those patients admitted with dementia were reviewed and compared with the findings of age/burn size-matched controls. The results support the premise that burn injuries in this patient population can be severe. Although not statistically significant, 22.2% of the study group patients required ventilatory support, and 75% required monitoring in the intensive care unit compared with the 15.3% and 61.6% of control patients who required ventilatory support and monitoring in the intensive care unit, respectively. Also, although not statistically significant, the mortality rate of the study group was 25%, almost double that of the control group (13.8%). No other significant differences were observed. These findings support the need for assistance and supervision with daily activity and burn prevention education for this population. As our population ages and we are faced with caring for those with dementia, further burn prevention is warranted. PMID:15879750

    Background: Several studies have assessed the correlation of fetal choroid plexus cyst (CPC) and the risk of congenital anomalies, but few ones have discussed isolated CPC (with no other abnormal sonographic finding). Objective: The aim of this study was to determine the outcome of isolated fetal choroid plexus cyst and to specify its clinical significance. Materials and Methods: This cross sectional study was carried out at Royan Institute in Tehran, Iran, between April 2009 and December 2012. All prenatal sonographies in this period of time were assessed using a computerized database and fetuses who had isolated CPC were recruited in the study. Sonography reports, mother serum screening test results, fetal echocardiography and amniocentesis were evaluated until birth. A follow-up phone call was made to all individuals to learn about the neonatal outcomes. Results: Overall, 6240 prenatal sonographies were performed in this setting during this period. Isolated CPC was detected in 64 fetuses. The results of double test (N=30), triple test (N=5) and fetal echocardiography (N =24) were normal. Quadruple test result showed 3 abnormal out of 29 cases that all had normal karyotypes. Four samples were dropped out due to premature rupture of membranes (N=3) and intrauterine fetal death (N=1). It was found that the outcomes of all remaining fetuses (N=60) were normal and no anomaly ones were seen until birth. Conclusion: Isolated CPC is a benign regressive condition with no clinical significance. PMID:26568762

    Peripheral nerve injuries result in reorganization within the contralateral hemisphere. Furthermore, recent animal and human studies have suggested that the plastic changes in response to peripheral nerve injury also include several areas of the ipsilateral hemisphere. The objective of this study was to map the inter-hemispheric plasticity in response to median nerve injury, to investigate normal differences in contra- and ipsilateral activation, and to study the impact of event-related or blocked functional magnetic resonance imaging (fMRI) design on ipsilateral activation. Four patients with median nerve injury at the wrist (injured and epineurally sutured >2 years earlier) and ten healthy volunteers were included. 3T fMRI was used to map the hemodynamic response to brain activity during tactile stimulation of the fingers, and a laterality index (LI) was calculated. Stimulation of Digits II-III of the injured hand resulted in a reduction in contralateral activation in the somatosensory area SI. Patients had a lower LI (0.21±0.15) compared to healthy controls (0.60±0.26) indicating greater ipsilateral activation of the primary somatosensory cortex. The spatial dispersion of the coordinates for areas SI and SII was larger in the ipsilateral than in the contralateral hemisphere in the healthy controls, and was increased in the contralateral hemisphere of the patients compared to the healthy controls. There was no difference in LI between the event-related and blocked paradigms. In conclusion, patients with median nerve injury have increased ipsilateral SI area activation, and spatially more dispersed contralateral SI activation during tactile stimulation of their injured hand. In normal subjects ipsilateral activation has larger spatial distribution than the contralateral. Previous findings in patients performed with the blocked fMRI paradigm were confirmed. The increase in ipsilateral SI activation may be due to an interhemispheric disinhibition associated with

    Patients with C5 or C6 radiculopathy complain of shoulder area pain or shoulder girdle weakness. Typical idiopathic neuralgic amyotrophy (INA) is also characterized by severe shoulder pain, followed by paresis of shoulder girdle muscles. Recent studies have demonstrated that magnetic resonance neurography (MRN) of the brachial plexus and magnetic resonance imaging (MRI) of the shoulder in patients with INA show high signal intensity (HSI) or thickening of the brachial plexus and changes in intramuscular denervation of the shoulder girdle. We evaluated the value of brachial plexus MRN and shoulder MRI in four patients with typical C5 or C6 radiculopathy. HSI of the brachial plexus was noted in all patients and intramuscular changes were observed in two patients who had symptoms over 4 weeks. Our results suggest that HSI or thickening of the brachial plexus and changes in intramuscular denervation of the shoulder girdle on MRN and MRI may not be specific for INA. PMID:27152289

    Spinal cord injuries (SCI) are serious medical conditions, which are associated with severe and potentially fatal risks and complications depending on the location and extent of injury. Traffic accidents, falls and recreational activities are the leading causes for traumatic SCI (TSCI) worldwide whereas non-traumatic spinal cord injuries (NTSCI) are mostly due to tumors and congenital diseases. As chronification of the injuries progresses other organ systems are affected including anatomical changes, the respiratory and cardiovascular systems and endocrinological pathways. All these effects have to be considered in the anesthesiological management of patients with SCI. Autonomic dysreflexia (AD) is the most dangerous and life-threatening complication in patients with chronic SCI above T6 that results from an overstimulation of sympathetic reflex circuits in the upper thoracic spine and can be fatal. This article summarizes the specific pathophysiology of SCI and how AD can be avoided as well as also providing anesthetists with strategies for perioperative and intensive care management of patients with SCI.

    Endogenous lipoid pneumonia (EnLP) is an uncommon non-life-threatening inflammatory lung disease that usually occurs in patients with conditions such as lung cancers, primary sclerosing cholangitis, and undifferentiated connective tissue disease. Here we report a case of EnLP in a paralytic and cachectic patient with bronchopneumonia after brain injury. A 40-year-old man experienced a severe brain injury in an automobile accident. He was treated for 1 month and his status plateaued. However, he became paralyzed and developed cachexia and ultimately died 145 days after the accident. Macroscopically, multifocal yellowish firm nodules were visible on scattered gross lesions throughout the lungs. Histologically, many foam cells had accumulated within the alveoli and alveolar walls accompanied by a surrounding interstitial infiltration of lymphocytes. The findings were in accordance with a diagnosis of EnLP. Bronchopneumonia was also noted. To our knowledge, there have been few reports of EnLP associated with bronchopneumonia and cachexia after brain injury. This uncommon pathogenesis should be well recognized by clinicians and forensic pathologists. The case reported here should prompt medical staff to increase the nutritional status and fight pulmonary infections in patients with brain injury to prevent the development of EnLP. PMID:26097618

    The aim of the study was to correlate multi-detector computed tomography (MDCT) grading with clinical severity and outcome in liver trauma patients without significant extrahepatic injury. Over a period of 2 years (2011-2013), all patients showing evidence of liver injury on contrast-enhanced CT (CECT) abdomen and without significant extrahepatic trauma were prospectively included in the study. Correlation between the CT injury grade and outcome in terms of mortality, duration of ICU/hospital stay, fluid and blood requirements, need for intervention and complications were assessed. The significance of the difference in mortality, duration of ICU/hospital stay, fluid requirement and blood requirements among the patients with various injury grades was assessed by Kruskal-Wallis test. The significance of the difference in need for intervention and complications among the patients with various injury grades was assessed by Fisher's exact test. A total of 198 patients were found to have evidence of hepatic injury on CECT. Out of 198 patients, 117 had insignificant extrahepatic trauma. The overall mean age for these 117 patients was 25.74 ± 15.53 (age range 2-84 years). Death rates according to AAST grades were 0 % in grades II and III, 6.89 % in grade IV and 9.09 % in grade V (p = 0.053). The mean ICU and total hospital stay for grade II was 1.32 and 5.91 days, for grade III was 1.76 and 8.48, for grade IV was 2.86 and 10.31 days and for grade V was 6.54 and 12 days, respectively (p = 0.0001 for ICU, p = 0.0003 for total stay). Mean input and fluid deficit according to various grades were 8634/2607 ml for grade II, 9535/2555 ml for grade III, 15,549/6242 ml for grade IV and 19,958/8280 ml for grade V (p value input-0.0016, output-input (fluid deficit)-0.0001). Average unit of RBC and sum of the blood products transfused were 1.73 and 2.26 for grade II, 2.18 and 2.72 for grade III, 3.03 and 6.27 for grade IV, 6.85 and 38.12 for grade V

    Spinal cord injuries (SCIs) often lead to impairment of the respiratory system and, consequently, restrictive respiratory changes. Paresis or paralysis of the respiratory muscles can lead to respiratory insufficiency, which is dependent on the level and completeness of the injury. Respiratory complications include hypoventilation, a reduction in surfactant production, mucus plugging, atelectasis, and pneumonia. Vital capacity (VC) is an indicator of overall pulmonary function; patients with severely impaired VC may require assisted ventilation. It is best to proceed with intubation under controlled circumstances rather than waiting until the condition becomes an emergency. Mechanical ventilation can adversely affect the structure and function of the diaphragm. Early tracheostomy following short orotracheal intubation is probably beneficial in selected patients. Weaning should start as soon as possible, and the best modality is progressive ventilator-free breathing (PVFB). Appropriate candidates can sometimes be freed from mechanical ventilation by electrical stimulation. Respiratory muscle training regimens may improve patients' inspiratory function following a SCI.

    Hyperactive reflexes are commonly observed in patients with spinal cord injury (SCI) but there is a lack of convenient and quantitative characterizations. Patellar tendon reflexes were examined in nine SCI patients and ten healthy control subjects by tapping the tendon using a hand-held instrumented hammer at various knee flexion angles, and the tapping force, quadriceps EMG, and knee extension torque were measured to characterize patellar tendon reflexes quantitatively in terms of the tendon reflex gain (Gtr), contraction rate (Rc), and reflex loop time delay (td). It was found that there are significant increases in Gtr and Rc and decrease in td in patients with spinal cord injury as compared to the controls (P < 0.05). This study presented a convenient and quantitative method to evaluate reflex excitability and muscle contraction dynamics. With proper simplifications, it can potentially be used for quantitative diagnosis and outcome evaluations of hyperreflexia in clinical settings. PMID:25654084

    Accepted indications for exploration in obstetrical brachial plexus palsy (OBPP) vary by center. Most agree that full elbow flexion against gravity at nine months of age implies high chance of spontaneous recovery and thus excludes a baby from surgical intervention. However, there are certain movements of the shoulder and forearm that may not be used frequently by the infant, but are extremely important functionally as they grow. These movements are difficult to assess in a baby and may lead to some clinicians to recommend conservative treatment, when this cohort of infants may in fact benefit substantially from surgery. A retrospective review was conducted on all infants managed surgically at the Brachial Plexus Center of a major children's hospital from 2009 to 2014. Further analysis identified five patients who had near-normal AMS scores for elbow flexion but who had weakness of shoulder abduction, flexion, external rotation, and/or forearm supination. In contrast to standard conservative management, this cohort underwent exploration, C5-6 neuroma excision, and sural nerve grafting. Data analysis was performed on this group to look for overall improvement in function. During an average follow-up period of 29 months, all patients made substantial gains in motor function of the shoulder and forearm, without loss of elbow flexion or extension, or worsening of overall outcome. In select infants with brachial plexus injuries but near-normal AMS scores for elbow flexion, surgical intervention may be indicated to achieve the best functional outcome. PMID:26806089

    Purpose. The purpose of the study was to evaluate the angiographic findings and results of embolotherapy in the management of lumbar artery trauma. Methods. All patients with lumbar artery injury who underwent angiography and percutaneous embolization in a state trauma center within a 10-year period were retrospectively reviewed. Radiological information and procedural reports were reviewed to assess immediate angiographic findings and embolization results. Long-term clinical outcome was obtained by communication with the trauma physicians as well as with chart review. Results. In a 10-year period, 255 trauma patients underwent abdominal aortography. Eleven of these patients (three women and eight men) suffered a lumbar artery injury. Angiography demonstrated active extravasation (in nine) and/or pseudoaneurysm (in four). Successful selective embolization of abnormal vessel(s) was performed in all patients. Coils were used in six patients, particles in one and gelfoam in five patients. Complications included one retroperitoneal abscess, which was treated successfully. One patient returned for embolization of an adjacent lumbar artery due to late pseudoaneurysm formation. Conclusions. In hemodynamically stable patients, selective embolization is a safe and effective method for immediate control of active extravasation, as well as to prevent future hemorrhage from an injured lumbar artery.

    Progressive, atrophic, asymmetrically distributed flaccid paresis of arm and hand muscles represents a frequent symptom of neuromuscular diseases that can be attributed to injury of the arm nerves, the plexus or the cervical roots. A timely and exact diagnosis is mandatory; however, the broad spectrum of differential diagnoses often represents a diagnostic challenge. A large variety of neuromuscular disorders need to be considered, encompassing autoimmune mediated inflammatory neuropathic conditions, such as multifocal motor neuropathy, as well as chronic degenerative and nerve compression disorders. This review provides an overview of the most frequent disorders of the upper plexus and cervical roots and summarizes the characteristic clinical features as well as electrodiagnostic and laboratory test results. In addition the diagnostic value of magnetic resonance imaging and sonography is discussed. PMID:24343110

  20. Lung Edema Clearance: Relevance to Patients with Lung Injury

    Pulmonary edema clearance is necessary for patients with lung injury to recover and survive. The mechanisms regulating edema clearance from the lungs are distinct from the factors contributing edema formation during injury. Edema clearance is effected via vectorial transport of Na+ out of the airspaces which generates an osmotic gradient causing water to follow the gradient out of the cells. This Na+ transport across the alveolar epithelium is mostly effected via apical Na+ and chloride channels and basolateral Na,K-ATPase. The Na,K-ATPase pumps Na+ out of the cell and K+ into the cell against their respective gradients in an ATP-consuming reaction. Two mechanisms contribute to the regulation of the Na,K-ATPase activity:recruitment of its subunits from intracellular compartments into the basolateral membrane, and transcriptional/translational regulation. Na,K-ATPase activity and edema clearance are increased by catecholamines, aldosterone, vasopressin, overexpression of the pump genes, and others. During lung injury, mechanisms regulating edema clearance are inhibited by yet unclear pathways. Better understanding of the mechanisms that regulate pulmonary edema clearance may lead to therapeutic interventions that counterbalance the inhibition of edema clearance during lung injury and improve the lungs’ ability to clear fluid, which is crucial for patient survival.

    Rehabilitation following acquired brain injury improves health outcomes, reduces disability, and improves quality of life. We assessed the cost effectiveness of inpatient rehabilitation after brain injury in individuals with brain injury admitted to the Irish national tertiary specialist rehabilitation centre in 2011. Patients' score on the Disability Rating Scale (DRS) was recorded on admission and at discharge after intensive inpatient rehabilitation. Cost savings attributed to the rehabilitation programme were calculated as the difference between direct care costs on admission and discharge. Direct costs of care were calculated as the weekly cost of the care-assistant hours required to care for patients on the basis of their level of disability or daily nursing-home bed cost when this was required. Of 63 patients, complete DRS information for admission and discharge was available for 41. DRS scores, and therefore average levels of functioning, differed significantly at admission (2.3, between mildly and moderately dependent) and discharge (1.1, independent in special environments, p<0.01). Average weekly care costs fell from €629 to €242, with costs recouped within 30 months. Thus, substantial savings result from inpatient rehabilitation, and these savings could have been greater had we considered also the economic benefit of enabling patients to return to employment.

    Traumatic brain injury (TBI) is a global problem and causes long-term disability in millions of individuals. This is a major problem for both military- and civilian-related populations. The prevalence of sleep disorders in individuals with TBI is very high, yet mostly unrecognized. Approximately 46% of all chronic TBI patients have sleep disorders, which require nocturnal polysomnography and the Multiple Sleep Latency Test for diagnosis. These disorders include sleep apnoea (23% of all TBI patients), post-traumatic hypersomnia (11%), narcolepsy (6%) and periodic limb movements (7%). Over half of all TBI patients will have insomnia complaints, most often with less severe injury and after personal assault, and half of these may be related to a circadian rhythm disorder. Hypothalamic injury with decreased levels of wake-promoting neurotransmitters such as hypocretin (orexin) and histamine may be involved in the pathophysiology of excessive sleepiness associated with TBI. These sleep disorders result in additional neurocognitive deficits and functional impairment, which might be attributed to the original brain injury itself and thus be left without specific treatment. Most standard treatment regimens of sleep disorders appear to be effective in these patients, including continuous positive airway pressure for sleep apnoea, pramipexole for periodic limb movements and cognitive behavioural therapy for insomnia. The role of wake-promoting agents and CNS stimulants for TBI-associated narcolepsy, post-traumatic hypersomnia and excessive daytime sleepiness requires further study with larger numbers of patients to determine effectiveness and benefit in this population. Future research with multiple collaborating centres should attempt to delineate the pathophysiology of TBI-associated sleep disorders, including CNS-derived hypersomnia and circadian rhythm disturbances, and determine definitive, effective treatment for associated sleep disorders.

    Ventilatory management of patients with acute lung injury (ALI), particularly its most severe subset, acute respiratory distress syndrome (ARDS), is complex. Newer lung protective strategies emphasize measures to enhance alveolar recruitment and avoid alveolar overdistention, thus minimizing the risk of ventilator-induced lung injury (VILI). Key components of such strategies include the use of smaller-than-conventional tidal volumes which maintain peak transpulmonary pressure below the pressure associated with overdistention, and titration of positive end-expiratory pressure to promote maximal alveolar recruitment. Novel techniques, including prone positioning, inverse ratio ventilation, tracheal gas insufflation, and high frequency ventilation, are considerations in severe ARDS. No single approach is best for all patients; adjustment of ventilatory parameters to individual characteristics, such as lung mechanics and gas exchange, is required. PMID:9891634

    The purpose of this study was to compare patient outcomes according to the method of diagnosing burn inhalation injury. After approval from the American Burn Association, the National Burn Repository Dataset Version 8.0 was queried for patients with a diagnosis of burn inhalation injury. Subgroups were analyzed by diagnostic method as defined by the National Burn Repository. All diagnostic methods listed for each patient were included, comparing mortality, hospital days, intensive care unit (ICU) days, and ventilator days (VDs). Z-tests, t-tests, and linear regression were used with a statistical significance of P value of less than .05. The database query yielded 9775 patients diagnosed with inhalation injury. The greatest increase in mortality was associated with diagnosis by bronchoscopy or carbon monoxide poisoning. A relative increase in hospital days was noted with diagnosis by bronchoscopy (9 days) or history (2 days). A relative increase in ICU days was associated with diagnosis according to bronchoscopy (8 days), clinical findings (2 days), or history (2 days). A relative increase in VDs was associated with diagnosis by bronchoscopy (6 days) or carbon monoxide poisoning (3 days). The combination of diagnosis by bronchoscopy and clinical findings increased the relative difference across all comparison measures. The combination of diagnosis by bronchoscopy and carbon monoxide poisoning exhibited decreased relative differences when compared with bronchoscopy alone. Diagnosis by laryngoscopy showed no mortality or association with poor outcomes. Bronchoscopic evidence of inhalation injury proved most useful, predicting increased mortality, hospital, ICU, and VDs. A combined diagnosis determined by clinical findings and bronchoscopy should be considered for clinical practice. PMID:26594867

    The prevalence of Pseudomonas aeruginosa colonization of patients with spinal cord injury was studied annually from 1976 to 1980. The urethra, perineum, rectum, drainage bag, and urine of patients on the spinal cord injury service were cultured. A total of 224 men and 32 women were studied. Most patients were managed with an external urinary collection system or padding, with or without intermittent catheterization. P. aeruginosa was cultured from one or more body sites (urethra, perineum, or rectum) in 65% of men and 18% of women. Drainage bags on the beds were frequently colonized with P. aeruginosa (73%). Significant bacteriuria with P. aeruginosa was present in 19% of the men and 13% of the women. P. aeruginosa colonization of body sites in men was closely associated with the use of an external urinary collection system. Significantly greater urethral and perineal colonization was found in men using an external urinary collection system. P. aeruginosa serotype 11 was the predominant serotype for the first 3 years, and the number of patients colonized with serotype 11 increased with length of hospital stay. The prevalence of serotype 11 significantly decreased in the last 2 years. The antibiotic susceptibility of the strains of P. aeruginosa isolated from these patients did not change in the 5 years, except that there was increasing susceptibility to carbenicillin in later years. This increasing susceptibility to carbenicillin was a reflection of a decreased prevalence of serotype 11 in these patients, since serotype 11 was more resistant than other serotypes to carbenicillin.

    Acute kidney injury (AKI) is increasingly being seen in patients with acute coronary syndromes (ACSs). This condition has a complex pathogenesis, an incidence that can reach 30% and it is associated with higher short-term and long-term morbidity and mortality. Nevertheless, AKI is still characterised by lack of a single accepted definition, unclear pathophysiology understanding and insensitive diagnostic tools that make its detection difficult, particularly in the setting of ACS. Recent data suggested that patients with AKI during ACS, even those in whom renal function seems to fully recover, face an increased, persisting risk of future AKI and may develop chronic kidney disease. Thus, in these patients, nephrology follow-up, after hospital discharge, and secondary preventive measures should possibly be implemented. In this review, we aim at providing a framework of knowledge to increase cardiologists' awareness of AKI, with the goal of improving the outcome of patients with ACS. PMID:26243789

    Functional ambulation is an expected outcome of physical therapy after burn injuries on the lower extremities. The purpose of this study was to document temporal and spatial gait parameters of adult patients with the use of the GAITRite system (CIR Systems Inc, Clifton, NJ) after the patients were burned on their lower extremities and to compare these results with previous data reported for normal subjects. Twenty-five adults with lower extremity burns (19 men and 6 women; mean age, 35.6+/-8.3 years) were evaluated within 5 days of discharge from an acute care facility. The GAITRite system, which consists of an electronic walkway that contains 6 sensor pads encapsulated in a rolled-up carpet, was used to collect temporal and spatial variables. The patients walked at their preferred rate of ambulation and completed 2 passes; the 2 passes were then averaged by the software to determine the patients' gait parameters. A 2-tailed t test was used for comparison of the mean values for the patients and the previously published data. The results indicated that for both men and women, cycle time and base of support were significantly higher (P < or = .01) in the patients with burn injuries than in normal subjects. For men, all of the remaining parameters were significantly lower (P < or = .01) in the patients with burns except stride length, which was not significantly different (P > .05). For women, stance time as a percentage of the gait cycle and cadence, velocity, step length, and stride length, were all significantly lower (P < or = .01) in the patients with burn injuries, whereas double support as a percentage of the gait cycle was not significantly different (P > .05) between the 2 groups. These results indicate that immediately after an acute care hospitalization, patients with lower extremity burns have significantly different gait patterns than gender-and age-matched normal subjects. Future studies are necessary to determine whether these impairments in gait limit

    Background: Outcomes of meniscus surgery are typically assessed with patient questionnaires that help capture symptoms and functional limitations but may not provide an accurate representation of underlying joint health. There are currently no performance-based measures of knee function in patients with symptomatic meniscus injury. Purpose: To assess the reproducibility, response to partial meniscectomy, and correlation with patient-reported questionnaire outcomes of novel performance-based knee function tests. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: A battery of 9 tests for activities that require knee movements essential for everyday living was developed. Intra- and interrater reproducibility was assessed in 50 meniscus tear patients completing the battery at 2 preoperative assessments with either the same or different examiners. Response to arthroscopic partial meniscectomy was evaluated in 35 of these patients 6 weeks after surgery. Subjects also completed the Knee Injury and Osteoarthritis Outcome Score (KOOS) and International Knee Documentation Committee (IKDC) questionnaires pre- and postoperatively. Results: The intrarater intraclass correlation coefficients (ICCs) were excellent for all tests (ICC > 0.8). Interrater ICC > 0.8 was observed for step-down, stair descent, star lunges, and timed treadmill travel. Performance on all tests improved significantly with surgery (P < .05), with the greatest improvement in sit-to-stand and stair ascent and descent. A greater percentage response to surgery was seen on questionnaire outcomes (20%-65%) than on performance-based tests (3%-15%). Moderate to poor correlations existed between the KOOS activities of daily living subscale and the performance-based tests (all ICCs ≤ 0.4). Conclusion: Performance-based knee function tests demonstrated good reproducibility and responsiveness in patients undergoing partial meniscectomy. Clinical Relevance: As both patient perception and functional

    Objective: Hand burns are commonly seen in patients with burn injury. In the past, focus was on lifesaving measures, but with advances in burn care during the last century, the paradigm shifted to digital salvage and eventually to functional digital salvage. Good outcomes are heavily dependent on the care that is rendered during the initial management of the burn. Methods: A retrospective medical record review was conducted through the Central Illinois Regional Burn Center Patient Registry. Patients with burn injury treated with upper extremity and hand escharotomy between January 1, 2000, and December 31, 2005, were included in the study. Results: We identified a total of 34 patients with 57 burned hands. Six hands required delayed amputation of digits despite recognition of neurovascular compromise and escharotomy, yielding a 10% amputation rate. No correlation could be drawn with regard to total body surface area, age, or sex. Conclusion: Important principles in the acute phase include early splinting, recognition of the need for escharotomy and complete escharotomy when necessary, early excision and grafting, and involvement of occupational therapy for splinting and to guide both active and passive exercises. Although uncommon, some extremity burns may require subsequent amputation despite prompt attention and optimal treatment. In our case series, the need for amputation after successful escharotomies of salvageable digits was associated with full-thickness and electrical burns. PMID:26977219

    Introduction: The thoracic outlet syndrome (TOS) is a rare complication of clavicular fracture, occurring in 0.5-9% of cases. In the literature from 1965 – 2010, 425 cases of TOS complicating a claviclular fracture were described. However, only 5 were observed after a surgical procedure of reduction and fixation. The causes of this complication were due to the presence of an exuberant callus, to technical surgery errors or to vascular lesions. In this paper we describe a case of brachial plexus plasy after osteosynthesis of clavicle fracture Case Report: A 48 year old female, presented to us with inveterate middle third clavicle fracture of 2 months duration. She was an alcoholic, smoker with an history of opiate abuse and was HCV positive. At two month the fracture was displaced with no signs of union and open rigid fixation with plate was done. The immediate postoperative patient had signs of neurologic injury. Five days after surgery showed paralysis of the ulnar nerve, at 10 days paralysis of the median nerve, radial and ulnar paresthesias in the territory of the C5-C6-C7-C8 roots. She was treated with rest, steroids and neurotrophic drugs. One month after surgery the patient had signs of complete denervation around the brachial plexus. Implant removal was done and in a month ulnar and median nerve functions recovered. At three months post implant removal the neurological picture returned to normal. Conclusion: We can say that TOS can be seen as arising secondary to an “iatrogenic compartment syndrome” justified by the particular anatomy of the space cost joint. The appropriateness of the intervention for removal of fixation devices is demonstrated by the fact that the patient has returned to her daily activities in the absence of symptoms and good functional recovery in about three months, despite fracture nonunion.

    We report a novel case of a mixed choroid plexus papilloma (CPP) and ependymoma with cartilaginous differentiation. This kind of mixed tumor has not been previously reported in the English literature. The patient was a 5-year-old girl, who presented with a 1-week history of fever and numbness of the right lower limb. Magnetic resonance imaging of the brain with gadolinium revealed a heterogeneously enhancing mass in the occipital horn of the left lateral ventricle. Histologically, the tumor showed an intermixed CPP area and a low-grade papillary ependymoma-like area, which was studded with cartilage islands and psammoma bodies. In many foci, direct transition of CPP and ependymoma was observed, but there were no high-grade features. We report this novel case, describe the unique microscopic and immunohistochemical features, and speculate on the pathogenesis. PMID:26670168

    This article provides an overview of hypothalamic and pituitary alterations in brain trauma, including the incidence of hypothalamic-pituitary damage, injury mechanisms, features of the hypothalamic-pituitary defects, and major hypothalamic-pituitary disturbances in brain trauma. While hypothalamic-pituitary lesions have been commonly described at postmortem examination, only a limited number of clinical cases of traumatic hypothalamic-pituitary dysfunction have been reported, probably because head injury of sufficient severity to cause hypothalamic and pituitary damage usually leads to early death. With the improvement in rescue measures, an increasing number of severely head-injured patients with hypothalamic-pituitary dysfunction will survive to be seen by clinicians. Patterns of endocrine abnormalities following brain trauma vary depending on whether the injury site is in the hypothalamus, the anterior or posterior pituitary, or the upper or lower portion of the pituitary stalk. Injury predominantly to the hypothalamus can produce dissociated ACTH-cortisol levels with no response to insulin-induced hypoglycemia and a limited or failed metopirone test, hypothyroxinemia with a preserved thyroid-stimulating hormone response to thyrotropin-releasing hormone, low gonadotropin levels with a normal response to gonadotropin-releasing hormone, a variable growth hormone (GH) level with a paradoxical rise in GH after glucose loading, hyperprolactinemia, the syndrome of inappropriate ADH secretion (SIADH), temporary or permanent diabetes insipidus (DI), disturbed glucose metabolism, and loss of body temperature control. Severe damage to the lower pituitary stalk or anterior lobe can cause low basal levels of all anterior pituitary hormones and eliminate responses to their releasing factors. Only a few cases showed typical features of hypothalamic or pituitary dysfunction. Most severe injuries are sufficient to damage both structures and produce a mixed endocrine picture

    Introduction The frequency of tracheostomy in patients with traumatic brain injury (TBI) contrasts with the lack of objective criteria for its management. The study arose from the need for a protocol in the decision to remove the tracheal tube. Objective To evaluate the applicability of a protocol for tracheal decannulation. Methods A prospective study with 20 patients, ranging between 21 and 85 years of age (average 33.55), 4 of whom were women (20%) and 16 were men (80%). All patients had been diagnosed by a neurologist as having TBI, and the anatomical region of the lesion was known. Patients were evaluated following criteria for tracheal decannulation through a clinical evaluation protocol developed by the authors. Results Decannulation was performed in 12 (60%) patients. Fourteen (70%) had a score greater than 8 on the Glasgow Coma Scale and only 2 (14%) of these were not able to undergo decannulation. Twelve (60%) patients maintained the breathing pattern with occlusion of the tube and were successfully decannulated. Of the 20 patients evaluated, 11 (55%) showed no signs suggestive of tracheal aspiration, and of these, 9 (82%) began training on occlusion of the cannula. The protocol was relevant to establish the beginning of the decannulation process. The clinical assessment should focus on the patient's condition to achieve early tracheal decannulation. Conclusion This study allowed, with the protocol, to establish six criteria for tracheal decannulation: level of consciousness, respiration, tracheal secretion, phonation, swallowing, and coughing.

    Traumatic brain injury (TBI) is a prevalent condition and there is limited visual perception research with this population. Here, we investigated perceptual organization changes in a rather homogeneous sample of closed head TBI outpatients with diffuse axonal injury only and no other known comorbidities. Patients had normal or corrected visual acuity. Perceptual organization was measured with the Leuven Perceptual Organization Screening Test (L-POST), a coherent motion task (CM) and the Leuven Embedded Figures Test (L-EFT). These tests were chosen to screen for deficits in different aspects of perceptual organization (L-POST), to evaluate local and global processing (L-EFT) and grouping in a dynamic set of stimuli (CM). TBI patients were significantly impaired compared to controls in all measures for both response time and accuracy, except for CM thresholds and object recognition subtests. The TBI group was similarly affected in all aspects of the L-EFT. TBI was also similarly affected in all perceptual factors of the L-POST. No significant correlations were found between scores and time post-injury, except for CM thresholds (rs=-0.74), which might explain the lack of group-level differences. The only score significantly correlated to IQ was L-EFT response time (rs=-0.67). These findings demonstrate that perceptual organization is diffusely affected in TBI and this effect has no substantial correlations with IQ. As many of the neuropsychological tests used to measure different cognitive functions involve some level of visual discrimination and perceptual organization demands, these results must be taken into account in the general neuropsychological evaluation of TBI patients.

    Daily interruption of sedative therapy and limitation of deep sedation have been shown in several randomized trials to reduce the duration of mechanical ventilation and hospital length of stay, and to improve the outcome of critically ill patients. However, patients with severe acute brain injury (ABI; including subjects with coma after traumatic brain injury, ischaemic/haemorrhagic stroke, cardiac arrest, status epilepticus) were excluded from these studies. Therefore, whether the new paradigm of minimal sedation can be translated to the neuro-ICU (NICU) is unclear. In patients with ABI, sedation has 'general' indications (control of anxiety, pain, discomfort, agitation, facilitation of mechanical ventilation) and 'neuro-specific' indications (reduction of cerebral metabolic demand, improved brain tolerance to ischaemia). Sedation also is an essential therapeutic component of intracranial pressure therapy, targeted temperature management and seizure control. Given the lack of large trials which have evaluated clinically relevant endpoints, sedative selection depends on the effect of each agent on cerebral and systemic haemodynamics. Titration and withdrawal of sedation in the NICU setting has to be balanced between the risk that interrupting sedation might exacerbate brain injury (e.g. intracranial pressure elevation) and the potential benefits of enhanced neurological function and reduced complications. In this review, we provide a concise summary of cerebral physiologic effects of sedatives and analgesics, the advantages/disadvantages of each agent, the comparative effects of standard sedatives (propofol and midazolam) and the emerging role of alternative drugs (ketamine). We suggest a pragmatic approach for the use of sedation-analgesia in the NICU, focusing on some practical aspects, including optimal titration and management of sedation withdrawal according to ABI severity.

    Patients reporting sensitivity to multiple chemicals at levels usually tolerated by the healthy population were administered standardized questionnaires to evaluate their symptoms and the exposures that aggravated these symptoms. Many patients were referred for medical tests. It is thought that patients with chemical sensitivity have organ abnormalities involving the liver, nervous system (brain, including limbic, peripheral, autonomic), immune system, and porphyrin metabolism, probably reflecting chemical injury to these systems. Laboratory results are not consistent with a psychologic origin of chemical sensitivity. Substantial overlap between chemical sensitivity, fibromyalgia, and chronic fatigue syndrome exists: the latter two conditions often involve chemical sensitivity and may even be the same disorder. Other disorders commonly seen in chemical sensitivity patients include headache (often migraine), chronic fatigue, musculoskeletal aching, chronic respiratory inflammation (rhinitis, sinusitis, laryngitis, asthma), attention deficit, and hyperactivity (affected younger children). Less common disorders include tremor, seizures, and mitral valve prolapse. Patients with these overlapping disorders should be evaluated for chemical sensitivity and excluded from control groups in future research. Agents whose exposures are associated with symptoms and suspected of causing onset of chemical sensitivity with chronic illness include gasoline, kerosene, natural gas, pesticides (especially chlordane and chlorpyrifos), solvents, new carpet and other renovation materials, adhesives/glues, fiberglass, carbonless copy paper, fabric softener, formaldehyde and glutaraldehyde, carpet shampoos (lauryl sulfate) and other cleaning agents, isocyanates, combustion products (poorly vented gas heaters, overheated batteries), and medications (dinitrochlorobenzene for warts, intranasally packed neosynephrine, prolonged antibiotics, and general anesthesia with petrochemicals).

    Rationale: Accurate, early identification of patients at risk for developing acute lung injury (ALI) provides the opportunity to test and implement secondary prevention strategies. Objectives: To determine the frequency and outcome of ALI development in patients at risk and validate a lung injury prediction score (LIPS). Methods: In this prospective multicenter observational cohort study, predisposing conditions and risk modifiers predictive of ALI development were identified from routine clinical data available during initial evaluation. The discrimination of the model was assessed with area under receiver operating curve (AUC). The risk of death from ALI was determined after adjustment for severity of illness and predisposing conditions. Measurements and Main Results: Twenty-two hospitals enrolled 5,584 patients at risk. ALI developed a median of 2 (interquartile range 1–4) days after initial evaluation in 377 (6.8%; 148 ALI-only, 229 adult respiratory distress syndrome) patients. The frequency of ALI varied according to predisposing conditions (from 3% in pancreatitis to 26% after smoke inhalation). LIPS discriminated patients who developed ALI from those who did not with an AUC of 0.80 (95% confidence interval, 0.78–0.82). When adjusted for severity of illness and predisposing conditions, development of ALI increased the risk of in-hospital death (odds ratio, 4.1; 95% confidence interval, 2.9–5.7). Conclusions: ALI occurrence varies according to predisposing conditions and carries an independently poor prognosis. Using routinely available clinical data, LIPS identifies patients at high risk for ALI early in the course of their illness. This model will alert clinicians about the risk of ALI and facilitate testing and implementation of ALI prevention strategies. Clinical trial registered with www.clinicaltrials.gov (NCT00889772).

    Objective To identify dermatological conditions following spinal cord injury (SCI) and analyze these conditions in relation to various characteristics of SCI. Design Retrospective chart review. Setting National Health Insurance Corporation Ilsan Hospital of Korea, Rehabilitation Center, Spinal Cord Unit. Participants Patients treated for SCI who were referred to dermatology for dermatological problems, 2000–2012. Results Of the 1408 SCI patients treated at the spinal cord unit, 253 patients with SCI were identified to have been referred to dermatology for skin problems and a total of 335 dermatological conditions were diagnosed. The most common dermatological finding was infectious (n = 123, 36.7%) followed by eczematous lesions (n = 109, 32.5%). Among the infectious lesions, fungal infection (n = 76, 61.8%) was the most common, followed by bacterial (n = 27, 21.9%) lesions. Seborrheic dermatitis (n = 59, 64.1%) was the most frequent eczematous lesion. Ingrown toenail occurred more frequently in tetraplegics whereas vascular skin lesions occurred more commonly in patients with paraplegia (P < 0.05). Xerotic dermatitis showed a higher occurrence within 12 months of injury rather than thereafter (P < 0.05). Of these, 72.4% of the infectious and 94.7% of the fungal skin lesions manifested below the neurological level of injury (NLI; P < 0.001) and 61.5% of the eczematous lesions and 94.9% of seborrheic dermatitis cases occurred above the NLI (P < 0.001). There was no significant difference in dermatological diagnoses between patients with neurologically complete and incomplete SCI. Conclusion The most common dermatological condition in patients with SCI among those referred to dermatology was fungal infection, followed by seborrheic dermatitis. Although dermatological problems after SCI are not critical in SCI outcome, they negatively affect the quality of life. Patients and caregivers should be educated about appropriate skin care and routine

    We have described 13 spinal cord injury patients with a complaint of diffuse, ongoing dysesthesias below the level of the lesion, which are burning in quality, and usually functionally limiting. Quantitative sensory and neurophysiological testing revealed relative preservation of the dorsal column functions in comparison to absence of spinothalamic system mediated functions. On the basis of these findings, we are speculating that such an imbalance between the spinothalamic and dorsal column systems is the main underlying mechanism of dysesthesias as a central nervous system misinterpretation of residual peripheral input.

    Context As with care giving and rehabilitation in chronic illnesses, the concern with traumatic brain injury (TBI), particularly with diffuse axonal injury (DAI), is that the caregivers are so overwhelmingly involved in caring and rehabilitation of the victim that in the process they become traumatized themselves. This review intends to shed light on the hidden and silent trauma sustained by the caregivers of severe brain injury survivors. Motor vehicle accident (MVA) is the highest contributor of TBI or DAI. The essence of trauma is the infliction of pain and suffering and having to bear the pain (i.e. by the TBI survivor) and the burden of having to take care and manage and rehabilitate the TBI survivor (i.e. by the TBI caregiver). Moreover many caregivers are not trained for their care giving task, thus compounding the stress of care giving and rehabilitating patients. Most research on TBI including DAI, focus on the survivors and not on the caregivers. TBI injury and its effects and impacts remain the core question of most studies, which are largely based on the quantitative approach. Evidence Acquisition Qualitative research can better assess human sufferings such as in the case of DAI trauma. While quantitative research can measure many psychometric parameters to assess some aspects of trauma conditions, qualitative research is able to fully reveal the meaning, ramification and experience of TBI trauma. Both care giving and rehabilitation are overwhelmingly demanding; hence , they may complicate the caregivers’ stress. However, some positive outcomes also exist. Results Caregivers involved in caring and rehabilitation of TBI victims may become mentally traumatized. Posttraumatic recovery of the TBI survivor can enhance the entire family’s closeness and bonding as well as improve the mental status of the caregiver. Conclusions A long-term longitudinal study encompassing integrated research is needed to fully understand the traumatic experiences of

    Barring unusual circumstances, sigmoid colostomy is the optimal technique for management of defecation in spinal cord injury (SCI) patients. We sought to provide evidence that a sigmoid colostomy is not difficult to perform in SCI patients and has better long-term results. The St. Louis Department of Veterans Affairs has a Commission on Accreditation of Rehabilitation Facilities (CARF)-approved SCI Unit. We reviewed the operative notes on all SCI patients who received a colostomy for fecal management by three ASCRS-certified colorectal surgeons at the St. Louis Department of Veterans Affairs from January 1, 2007 to November 26, 2012. There were 27 operations for which the recorded indication for surgery suggested that the primary disorder was SCI. Fourteen had traumatic SCI of the thoracic and/or lumbar spine and were evaluable. Of these 14 patients, 12 had laparoscopic sigmoid colostomy and two had open sigmoid colostomy. We encountered one evaluable patient with a remarkably large amount of retroperitoneal bony debris who successfully underwent laparoscopic sigmoid colostomy. In conclusion, sigmoid colostomy is the consensus optimal procedure for fecal management in SCI patients. Laparoscopic procedures are preferred. Care providers should specify sigmoid colostomy when contacting a surgeon. PMID:27099066

    Twenty-four patients with spinal cord injuries were studied to correlate their responses to intra-abdominal disease with the level and completeness of the cord lesion. Patients with complete cervical lesions and lesions of the upper part of the thoracic region (C-4 to T-6) usually responded by early noniocalized abdominal pain associated with signs of autonomic dysreflexia. As the disease progressed to involve the parietal peritoneum, these patients were more capable of localizing pain to the corresponding dermatome, whereas patients with incomplete lesions were able to localize their pain earlier. Patients with lumbar lesions and lesions of the lower part of the thoracic region (T-7 to L-3) were able to localize their pain earlier than those with lesions located higher in the thoracic region. All patients had delayed diagnoses except those with hemorrhage of the upper part of the gastrointestinal tract. Irrespective of level of cord lesion, increased pulse rate was themost prominent objective acute intra-abdominal pathologic finding. Shoulder pain in the quadriplegic is a most helpful sign.

    Pleural effusions occur frequently in mechanically ventilated patients, but no consensus exists regarding the clinical benefit of effusion drainage. We sought to determine the impact of thoracentesis on gas exchange in patients with differing severities of acute lung injury (ALI). A retrospective analysis was conducted on therapeutic thoracenteses performed on intubated patients in an adult surgical intensive care unit of a tertiary center. Effusions judged by ultrasound to be 400 mL or larger were drained. Subjects were divided into groups based on their initial P:F ratios: normal >300, ALI 200 to 300, and acute respiratory distress syndrome (ARDS) <200. Baseline characteristics, physiologic variables, arterial blood gases, and ventilator settings before and after the intervention were analyzed. The primary end point was the change in measures of oxygenation. Significant improvements in P:F ratios (mean ± SD) were seen only in patients with ARDS (50.4 ± 38.5, P = 0.001) and ALI (90.6 ± 161.7, P = 0.022). Statistically significant improvement was observed in the pO2 (31.1, P = 0.005) and O2 saturation (4.1, P < 0.001) of the ARDS group. The volume of effusion removed did not correlate with changes in individual patient's oxygenation. These data support the role of therapeutic thoracentesis for intubated patients with abnormal P:F ratios. PMID:27099064

    Abstract We report on patients with post-traumatic fatigue and hypersomnia who showed injury of the lower portion of the ascending reticular activating system (ARAS) between the pontine reticular formation (RF) and the intralaminar thalamic nucleus (ILN) following mild traumatic brain injury (TBI), using diffusion tensor tractography (DTT). Two patients with mild TBI resulting from a car accident were enrolled in this study. Patient 1 was a 51-year-old woman showed abnormalities as 6.9 (cut off: 3.7 points) and 18 (cut off: 10) on the Fatigue Severity Scale and the Epworth Sleepiness Scale at 11 months after onset. Patient 2 was a 64-year-old woman who revealed abnormalities on the Fatigue Severity Scale and the Epworth Sleepiness Scale with 6.8 and 19 at 3 months after onset. In both patients, the upper ARAS in which the neural connectivity of the ILN to the cerebral cortex did not show significant abnormalities. However, we observed the narrowing of the left dorsal lower ARAS between the pontine RF and the ILN in both patients and the tearing (patient 1) and narrowing (patient 2) of the left ventral lower ARAS between the pontine RF and the hypothalamus. Injuries of the dorsal and ventral lower ARAS were demonstrated in patients with fatigue and hypersomnia following mild TBI. We believe that these injuries of the ARAS might be a pathogenetic mechanism of fatigue and hypersomnia in patients with TBI. PMID:26871783

    OBJECT Mapping of the fascicular anatomy of the brachial plexus could provide the nerve surgeon with knowledge of fascicular orientation in spinal nerves of the brachial plexus. This knowledge might improve the surgical outcome of nerve grafting in brachial plexus injuries by anastomosing related fascicles and avoiding possible axonal misrouting. The objective of this study was to map the fascicular topography in the spinal nerves of the brachial plexus. METHODS The entire right-sided brachial plexus of 25 adult male cadavers was dissected, including all 5 spinal nerves (C5-T1), from approximately 5 mm distal to their exit from the intervertebral foramina, to proximal 1 cm of distal branches. All spinal nerves were tagged on the cranial aspect of their circumference using 10-0 nylon suture for orientation. The fascicular dissection of the C5-T1 spinal nerves was performed under microscopic magnification. The area occupied by different nerve fascicles was then expressed as a percentage of the total cross-sectional area of a spinal nerve. RESULTS The localization of fascicular groups was fairly consistent in all spinal nerves. Overall, 4% of the plexus supplies the suprascapular nerve, 31% supplies the medial cord (comprising the ulnar nerve and medial root of the median nerve [MN]), 27.2% supplies the lateral cord (comprising the musculocutaneous nerve and lateral root of the MN), and 37.8% supplies the posterior cord (comprising the axillary and radial nerves). CONCLUSIONS The fascicular dissection and definitive anatomical localization of fascicular groups is feasible in plexal spinal nerves. The knowledge of exact fascicular location might be translatable to the operating room and can be used to anastomose related fascicles in brachial plexus surgery, thereby avoiding the possibility of axonal misrouting and improving the results of plexal reconstruction.

    PubMed

    Berić, A

    1992-01-01

    The amplitude and latency of somatosensory evoked potentials (SEPs) in healthy subjects depend on intensity of stimulation. The effect of this parameter on SEPs in patients with neurologic disorders has not been systematically studied, although it could have a profound impact if SEPs are to be used for prognostication. We have compared the latency and amplitude of SEPs in healthy subjects and patients with spinal cord injury (SCI). Stimulation intensity was standardized at two different biologically calibrated levels. Cortical SEPs in patients with SCI showed greater decrease in latency and increase in amplitude with increased intensity of stimulation in comparison to healthy subjects. These phenomena were observed in the majority of patients with incomplete SCI who subsequently showed improvement in cortical SEPs. We observed situations in which the SEP was absent with the usual intensity of stimulation and present only with the stronger stimulation intensity. Furthermore, SEP latencies often changed dramatically with different intensities of stimulation, potentially making any calculation of central conduction velocity meaningless without precise standardization of stimulation. These findings demonstrate a necessity for a biological calibration of stimulation intensity to improve the repeatability of SEPs. We suggest the use of two different standardized intensities of stimulation for SEP studies in SCI patients, one of which should be stronger than the intensity presently recommended. PMID:1578234

    Intermittent catheterisation is the preferred method of managing the neurogenic bladder in patients with spinal cord injury. However, spinal cord physicians experienced problems when trying to implement an intermittent catheterisation regime in some spinal cord injury patients in the northwest of England. We present illustrative cases to describe practical difficulties encountered by patients while trying to adopt an intermittent catheterisation regime. Barriers to intermittent catheterisation are (1) caregivers or nurses are not available to carry out five or six catheterisations a day; (2) lack of time to perform intermittent catheterisations; (3) unavailability of suitable toilet facilities in public places, including restaurants and offices; (4) redundant prepuce in a male patient, which prevents ready access to urethral meatus; (5) urethral false passage; (6) urethral sphincter spasm requiring the use of flexible-tip catheters and á-adrenoceptor-blocking drugs; (7) reluctance to perform intermittent catheterisation in patients >60 years by some health professionals; and (8) difficulty in accessing the urethral meatus for catheterisation while the patient is sitting up, especially in female patients. These cases demonstrate the urgent need for provision of trained caregivers who can perform intermittent catheterisation, and improvement in public facilities that are suitable for performing catheterisation in spinal cord injury patients. Further, vigilance should be exercised during each catheterisation in order to prevent complications, such as urethral trauma and consequent false passages. Health professionals should make additional efforts to implement intermittent catheterisation in female spinal cord injury patients and in those >60 years. PMID:21218264

    The concept of a closed peri-neurovascular space surrounding the cervicobrachial plexus, introduced by A. Winnie, allows the blockade of the cervical and brachial plexuses by means of a single puncture technique. The single puncture has positive advantages: 1. The rapidity of the blockade; 2. The simplicity of the blockade; 3. Comfort for the patient. The landmarks are easy to make. As with epidural blockade, the injection level and the volume of local anesthetic determine the quality and extent of the block. The traditional indication is surgery of the shoulder and of the supraclavicular area. A new indication seems to be the implantation of a cardiac pacemaker. Complications often quoted in literature are Horner syndrome-a minor complication-and blockade of the ascending branches of the recurrent laryngeal nerve and of the phrenic nerve. The risk of a pneumothorax is almost nil. PMID:7324853

    Body injuries are very serious problems in industrialised countries and they are frequent causes of fatalities in our times. The variety and multiple combinations of body injuries are a challenge for the trauma team. On the basis of clinical and radiological documentation 315 patients with multiple injuries of the locomotor system (MILS) were included in the study. The criterion for inclusion of the patients into the study group was identification of MILS. The study showed that these injuries often involve young people (53%) (predominantly men) aged between 16 and 45 years. Road accidents were the most frequent cause of injuries -80.6%. MILS affected the lower limb in 49.,4%, upper limb in 33.2% and pelvis in 14.1%; 75% of the patients studied also suffered from concomitant injuries. The head and brain were involved in 92.9%, chest in 31.5% and abdomen in 21.3%. The mortality index for the population studied was 14%. An increasing value of the Injury Severity Score (ISS) or New Injury Severity Score (NISS) caused delay in surgical management of bone injuries and correlated with prolonged hospitalisation. Analysis emphasised the usefulness of the NISS as a valuable prognostic instrument in assessment of severity of injuries in patients with multiple injuries of the locomotor system. PMID:17609954

    Abstract Little information is available regarding the risk of nongenitourinary (GU) cancers in patients with spinal cord injury (SCI). The authors conducted a nationwide population-based study to investigate whether a higher risk of non-GU cancer is seen among patients with SCI. Data retrieved from the National Health Insurance Research Database of Taiwan were used in this study. A total of 41,900 patients diagnosed with SCI between 2000 and 2011 were identified from the National Health Insurance Research Database and comprised the SCI cohort. Each of these patients was randomly frequency matched with 4 people from the general population (without SCI) according to age, sex, comorbidities, and index year. Cox proportional hazards regression analysis was used to calculate adjusted hazard ratios and 95% confidence intervals and determine how SCI affected non-GU cancer risk. No significant difference in overall non-GU cancer risk was observed between the SCI and control groups. The patients with SCI exhibited a significantly higher risk of developing esophageal, liver, and hematologic malignancies compared with those without SCI. By contrast, the SCI cohort had a significantly lower risk of colorectal cancer compared with the non-SCI cohort (adjusted hazard ratio = 0.80, 95% confidence interval = 0.69–0.93). Additional stratified analyses by sex, age, and follow-up duration revealed various correlations between SCI and non-GU cancer risk. The patients with SCI exhibited higher risk of esophageal, liver, and hematologic malignancies but a lower risk of colorectal cancer compared with those without SCI. The diverse patterns of cancer risk among the patients with SCI may be related to the complications of chronic SCI. PMID:26765443

    Psychiatric disturbance is common and disabling after traumatic brain injury (TBI). Few studies have investigated the trajectory of psychiatric symptoms in the first 6 months postinjury, when monitoring and early treatment might prevent persistent difficulties. The aim of this study was to examine the trajectory of psychiatric symptoms 1-6 months post-TBI, the patient/injury characteristics associated with changes, and characteristics predictive of persisting symptoms. A secondary analysis was performed on data from a clinical trial with three data collection points. Across eight centers, 872 participants with complicated mild to severe TBI were administered the Brief Symptom Inventory (BSI) at 30, 90, and 180 days postinjury. Mixed-effects models were used to assess longitudinal changes in the BSI Global Severity Index (GSI). Multi-variate logistic regression was used to assess predictors of clinically significant GSI elevations persisting to 6 months post-TBI. In general, GSI scores improved over time. Women improved faster than men; race/ethnicity was also significantly associated with rate of change, with Hispanics showing the most and African Americans the least improvement. Clinically significant psychiatric symptoms (caseness) occurred in 42% of the sample at 6 months, and more than one type of symptom was common. Significant predictors of caseness included African American race, age from 30 to 60 years, longer post-traumatic amnesia (PTA) duration, pre-TBI unemployment, and pre-TBI risky alcohol use. Findings indicate that psychiatric symptoms are common in the first 6 months post-TBI and frequently extend beyond the depression and anxiety symptoms that may be most commonly screened. Patients with longer PTA and preinjury alcohol misuse may need more intensive monitoring for symptom persistence. PMID:24237113

    AIMS Whether glucocorticoids induce gastric mucosal injury remains uncertain. We investigated whether very high-dose steroids caused gastric mucosal injury in systemic lupus erythematous (SLE) patients and evaluated the possible risk factors for mucosal injury. METHODS In this prospective paired study, 67 SLE patients who had received pulse methylprednisolone therapy were enrolled. Each patient underwent endoscopic examination and tissue and blood sampling before and after pulse steroid therapy. Mucosal injury was diagnosed if the follow-up injury scale was higher than the initial scale. Examined parameters included Helicobacter pylori infection, cyclooxygenase (COX)-1 and COX-2 activity, and current nonsteroidal anti-inflammatory drug (NSAID) usage including aspirin. RESULTS Eleven (16.4%) of 67 cases who developed gastric mucosal injury after pulse therapy had significantly higher rates of peptic ulcer history, NSAID/aspirin use, lower gastric thromboxane B2 and prostaglandin E2 levels when compared with cases without gastric mucosal injury (P < 0.05). Infection by H. pylori was not a risk factor for gastric mucosal injury. Multivariate logistic regression analysis showed that NSAID/aspirin use was the only risk factor for gastric mucosal injury in these patients (odds ratio 26.99, 95% confidence interval 4.91, 148.57, P < 0.0001). Pulse steroid therapy alone did not induce gastric mucosal injury in fifty SLE patients without taking any NSAID/aspirin. CONCLUSIONS Use of NSAIDs/aspirin, but not H. pylori infection, increases gastric mucosal injury in SLE patients receiving pulse methylprednisolone therapy. Very high-dose steroids de novo seem not to induce gastric mucosal injury in these patients. A larger case-controlled study enrolling a heterogeneous population is needed to clarify the role of glucocorticoids in gastric mucosal injury. PMID:19694746

    Human intestinal flora comprises thousands of bacterial species. Growth and composition of intestinal microbiota is dependent on various parameters, including immune mechanisms, dietary factors and intestinal motility. Patients with spinal cord injury (SCI) frequently display neurogenic bowel dysfunction due to the absence of central nervous system control over the gastrointestinal system. Considering the bowel dysfunction and altered colonic transit time in patients with SCI, we hypothesized the presence of a significant change in the composition of their gut microbiome. The objective of this study was to characterize the gut microbiota in adult SCI patients with different types of bowel dysfunction. We tested our hypothesis on 30 SCI patients (15 upper motor neuron [UMN] bowel syndrome, 15 lower motor neuron [LMN] bowel syndrome) and 10 healthy controls using the 16S rRNA sequencing. Gut microbial patterns were sampled from feces. Independent of study groups, gut microbiota of the participants were dominated by Blautia, Bifidobacterium, Faecalibacterium and Ruminococcus. When we compared all study groups, Roseburia, Pseudobutyrivibrio, Dialister, Marvinbryantia and Megamonas appeared as the genera that were statistically different between groups. In comparison to the healthy group, total bacterial counts of Pseudobutyrivibrio, Dialister and Megamonas genera were significantly lower in UMN bowel dysfunction group. The total bacterial count of Marvinbryantia genus was significantly lower in UMN bowel dysfunction group when compared to the LMN group. Total bacterial counts of Roseburia, Pseudobutyrivibrio and Megamonas genera were significantly lower in LMN bowel dysfunction group when compared to healthy groups. Our results demonstrate for the first time that butyrate-producing members are specifically reduced in SCI patients when compared to healthy subjects. The results of this study would be of interest since to our knowledge, microbiome-associated studies

    2016-01-01

    Patients with cancer represent a growing group among actual ICU admissions (up to 20 %). Due to their increased susceptibility to infectious and noninfectious complications related to the underlying cancer itself or its treatment, these patients frequently develop acute kidney injury (AKI). A wide variety of definitions for AKI are still used in the cancer literature, despite existing guidelines on definitions and staging of AKI. Alternative diagnostic investigations such as Cystatin C and urinary biomarkers are discussed briefly. This review summarizes the literature between 2010 and 2015 on epidemiology and prognosis of AKI in this population. Overall, the causes of AKI in the setting of malignancy are similar to those in other clinical settings, including preexisting chronic kidney disease. In addition, nephrotoxicity induced by the anticancer treatments including the more recently introduced targeted therapies is increasingly observed. However, data are sometimes difficult to interpret because they are often presented from the oncological rather than from the nephrological point of view. Because the development of the acute tumor lysis syndrome is one of the major causes of AKI in patients with a high tumor burden or a high cell turnover, the diagnosis, risk factors, and preventive measures of the syndrome will be discussed. Finally, we will briefly discuss renal replacement therapy modalities and the emergence of chronic kidney disease in the growing subgroup of critically ill post-AKI survivors. PMID:27480256

    The objective of this study was to determine the prevalence of road traffic crashes (RTC)-related maxillofacial injuries, the concomitant injuries occurring with them, and to assess the relationship between the severity of maxillofacial and concomitant injuries. This was a prospective study involving 201 victims of RTC seen at the Accident and Emergency Department of the University College Hospital, Ibadan with maxillofacial injuries during the study period. Demographic data of the patients, the types of maxillofacial injuries, and concomitant injuries sustained were recorded. Severity of maxillofacial injury was determined using the maxillofacial injury severity scale (MFISS), while the severity of concomitant injuries was based on the ISS. Correlations between types and severity of maxillofacial injury and types and severity of concomitant injury were conducted to determine the predictability of concomitant injuries based on maxillofacial injury severity. Data were processed using SPSS Statistical software (SPSS, version 20.0 for windows, IBM SPSS Inc, Chicago, IL). Maxillofacial injuries constituted 25.4% of RTC-related admission by the Accident and Emergency Department. A total of 151 (75.1%) patients who presented with concomitant injuries participated in the study. Eighty-one (53.6%) sustained injuries to more than one body region. Head injury was the commonest (99, 65.6%) concomitant injury, followed by orthopedic injury (69, 45.7%). Increasing severity of maxillofacial injury showed a positive correlation with increasing ISS. Also, positive correlation was noted with increasing severity of maxillofacial injury and presence of polytrauma (p = 0.01), traumatic brain injury (p = 0.034), and eye injuries (p = 0.034). There was a high prevalence of maxillofacial injuries in victims of RTC. There was a high incidence of concomitant injuries noted with these maxillofacial injuries. Significantly, this study showed a direct relationship between the

    The cerebrovascular time constant (τ) theoretically estimates how fast the cerebral arterial bed is filled by blood volume after a sudden change in arterial blood pressure during one cardiac cycle. The aim of this study was to assess the time constant of the cerebral arterial bed in patients with traumatic brain injury (TBI) with and without intracranial hematomas (IH). We examined 116 patients with severe TBI (mean 35 ± 15 years, 61 men, 55 women). The first group included 58 patients without IH and the second group included 58 patients with epidural (7), subdural (48), and multiple (3) hematomas. Perfusion computed tomography (PCT) was performed 1-12 days after TBI in the first group and 2-8 days after surgical evacuation of the hematoma in the second group. Arteriovenous amplitude of regional cerebral blood volume oscillation was calculated as the difference between arterial and venous blood volume in the "region of interest" of 1 cm(2). Mean arterial pressure was measured and the flow rate of the middle cerebral artery was recorded with transcranial Doppler ultrasound after PCT. The time constant was calculated by the formula modified by Kasprowicz. The τ was shorter (p = 0.05) in both groups 1 and 2 in comparison with normal data. The time constant in group 2 was shorter than in group 1, both on the side of the former hematoma (р = 0.012) and on the contralateral side (р = 0.044). The results indicate failure of autoregulation of cerebral capillary blood flow in severe TBI, which increases in patients with polytrauma and traumatic IH. PMID:26463964

    Abstract The periaqueductal gray (PAG) plays a pivotal role in pain modulation. We attempted to examine the relation between injury of the PAG and central pain in patients with mild traumatic brain injury (TBI). Sixty-one patients with mild TBI with central pain and 31 healthy control subjects were recruited for this study. Visual analog scale (VAS) was used for evaluation of central pain. The region of interest was defined for the PAG and the fractional anisotropy (FA) and apparent diffusion coefficient (ADC) were measured. The FA value was significantly lower in the patient group than in the control group (P < 0.05). However, no significant difference in the ADC value was observed between the patient and control groups (P > 0.05). VAS score of the patient group showed significant moderate negative correlation with the FA (r = −0.38), while no significant correlation was observed between VAS score and the ADC value (P < 0.05). We demonstrated injury of the PAG in patients with central pain following mild TBI and the degree of injury of the PAG was closely related to the degree of central pain. PMID:27368020

    2016-03-01

    Spinal injuries from blunt trauma are uncommon in pediatric patients, representing only about 1.5% of all blunt trauma patients. However, the potentially fatal consequences of spinal injuries make them of great concern to emergency clinicians. Clinical goals in the emergency department are to identify all injuries using selective imaging and to minimize further harm from spinal cord injury. Achieving these goals requires an understanding of the age-related physiologic differences that affect patterns of injury and radiologic interpretation in children, as well as an appreciation of high-risk clinical clues and mechanisms. This issue reviews current approaches to prehospital immobilization, identification of low-risk patients who may be clinically cleared from immobilization, a rational approach to the use of radiologic imaging, and the existing evidence for medical management of spinal cord injuries.

    Recent studies indicate that the choroid plexus has important physiologic and pathologic roles in Alzheimer disease (AD). To obtain additional insight on choroid plexus function, we performed a proteomic analysis of choroid plexus samples from patients with AD stages I to II (n = 16), III to IV (n = 16), and V to VI (n = 11) and 7 age-matched control subjects. We used 2-dimensional differential gel electrophoresis coupled with mass spectrometry to generate a complete picture of changes in choroid plexus protein expression occurring in AD patients. We identified 6 proteins: 14-3-3 β/α, 14-3-3 ε, moesin, proteasome activator complex subunit 1, annexin V, and aldehyde dehydrogenase, which were significantly regulated in AD patient samples (p < 0.05, >1.5-fold variation in expression vs control samples). These proteins are implicated in major physiologic functions including mitochondrial dysfunction and apoptosis regulation. These findings contribute additional significance to the emerging importance of molecular and functional changes of choroid plexus function in the pathophysiology of AD. PMID:25756589

    Although α-glucosidase inhibitors (AGIs) are commonly used for controlling postprandial blood glucose, AGIs-induced liver injuries have been reported. However, the relationship between AGIs and liver injuries in advanced chronic kidney disease (CKD) patients remains unexplored. In this nationwide case-control study, we recruited 1765 advanced diabetic CKD patients, who received AGIs therapy from January 1, 2000 to December 31, 2010 as the study sample and 5295 matched controls. Recent and former AGIs users were defined as patients who received the AGIs prescription for 30–60 d and 30–210 d before the event of liver injury. The risk of AGIs-induced liver injury was examined using time-dependent Cox proportional hazards model. Liver injury occurred in 3.9% of patients in the study group and 3.3% of patients in the control group. AGIs use did not increase the risk of liver injury in advanced CKD patients (P = 0.19). The stratified analysis indicated no increased risk of liver injury in all AGIs-using subgroups (all P > 0.05). The available evidence supports extending the use of AGIs without increasing the risk of liver injury in patients with advanced CKD. Additional randomized controlled trials are warranted to confirm our results. PMID:26751038

    Fifty-one patients with mild (n = 14), moderate (n = 10) and severe traumatic brain injury (n = 27) received early rehabilitation. Level of consciousness was evaluated using the Glasgow Coma Score. Functional level was determined using the Glasgow Outcome Score, whilst mobility was evaluated using the Mobility Scale for Acute Stroke. Activities of daily living were assessed using the Barthel Index. Following Bobath neurodevelopmental therapy, the level of consciousness was significantly improved in patients with moderate and severe traumatic brain injury, but was not greatly influenced in patients with mild traumatic brain injury. Mobility and functional level were significantly improved in patients with mild, moderate and severe traumatic brain injury. Gait recovery was more obvious in patients with mild traumatic brain injury than in patients with moderate and severe traumatic brain injury. Activities of daily living showed an improvement but this was insignificant except for patients with severe traumatic brain injury. Nevertheless, complete recovery was not acquired at discharge. Multiple regression analysis showed that gait and Glasgow Coma Scale scores can be considered predictors of functional outcomes following traumatic brain injury. PMID:25624828

    Neurinomas, also referred to as neurilemmomas and schwannomas, are rare benign tumours of the peripheral nerves, a low proportion of which arise from the brachial plexus. Authors report a case of an ancient schwannoma arising from the brachial plexus. The tumour, usually asymptomatic, may cause sensory radicular symptoms, or rarely motor deficits in the involved arm. Enucleation of the tumour from the nerve without damage to any of the fascicles is the correct treatment. PMID:10710825

    An 11-month-old male underwent surgery for a choroid plexus neoplasm, which on histologic examination was diagnosed as a benign papilloma. Chromosome analysis showed a karyotype of 55,XY,+7+7,+8,+9,+12,+12,+15,+20,+21 in all 20 metaphases analyzed. This is only the third benign choroid plexus papilloma that has been karyotyped, with the others being normal and hypodiploid (33 chromosomes). Three malignant choroid plexus carcinomas have also been analyzed, two with normal karyotypes and one hypodiploid (34 - 35 chromosomes). The two hypoidiploid neoplasms lack chromosomes 2, 3, 4, 5, 10, 13, 14, 17 and 18. Since the chromosomes that are lost in the hypodiploid neoplasms are different from the chromosomes gained in our tumor, it appears that the dosage of specific chromosomes is important in the origin of choroid plexus neoplasms. Benign choroid plexus papillomas can be difficult to differentiate from choroid plexus carcinomas. With the data available so far, it does not appear that cytogenetics can assist in making the diagnosis.

    Twenty-eight patients with surgically documented and classified hepatic injury were studied by computed tomography (CT) in the postoperative period.CT demonstrated no abnormalities in 12 of these patients, most of whom has sustained simple lacerations of the liver. Of the 16 patients with abnormal scans, perihepatic fluid collections were present in six, five of whom had simple lacerations at surgery. The other 10 patients had CT evidence of parenchymal abnormalities, and all of these had sustained major hepatic injuries. CT is usful in depicting the postoperative anatomy, and in many cases demonstrates the nature and extent of damage; the likelihood of finding an abnormality varies with the severity of the injury, even though repair has been attempted. The frequent problem of postoperative sepsis is also amenable to CT evaluation, but the changes demonstrated are often nonspecific and the possibility of residual hepatic injury has to be considered. Finally, CT can document healing of parenchymal injury.

    Objective To compare the swallowing characteristics of dysphagic patients with traumatic brain injury (TBI) with those of dysphagic stroke patients. Methods Forty-one patients with TBI were selected from medical records (between December 2004 to March 2013) and matched to patients with stroke (n=41) based on age, sex, and disease duration. Patients' swallowing characteristics were analyzed retrospectively using a videofluoroscopic swallowing study (VFSS) and compared between both groups. Following thorough review of medical records, patients who had a history of diseases that could affect swallowing function at the time of the study were excluded. Dysphagia characteristics and severity were evaluated using the American Speech-Language-Hearing Association National Outcome Measurement System swallowing scale, clinical dysphagia scale, and the videofluoroscopic dysphagia scale. Results There was a significant difference in radiological lesion location (p=0.024) between the two groups. The most common VFSS finding was aspiration or penetration, followed by decreased laryngeal elevation and reduced epiglottis inversion. Swallowing function, VFSS findings, or quantified dysphagia severity showed no significant differences between the groups. In a subgroup analysis of TBI patients, the incidence of tube feeding was higher in patients with surgical intervention than in those without (p=0.011). Conclusion The swallowing characteristics of dysphagic patients after TBI were comparable to those of dysphagic stroke patients. Common VFSS findings comprised aspiration or penetration, decreased laryngeal elevation, and reduced epiglottis inversion. Patients who underwent surgical intervention after TBI were at high risk of tube feeding requirement. PMID:27446779

    Magnetic resonance images (MRI) of brachial plexus anatomy bilaterally, not possible by plain radiographs or CT, were presented to the Vascular Surgery, Neurology, and the Neurosurgery departments. Patients were requested for MRI of their brachial plexus. They were referred for imaging and the imaging results were presented to the faculty and housestaff. Our technique was accepted and adopted to begin referrals for MRI evaluation of brachial plexopathy. Over 175 patients have been studied. Eighty-five patients were imaged with the 1.5 Tesla magnet (Signa; General Electric Medical Systems, Milwaukee, WI) 3-D reconstruction MRI. Coronal, transverse (axial), oblique transverse, and sagittal plane T1-weighted and selected T2-weighted pulse sequences were obtained at 4-5 mm slice thickness, 40-45 full field of view, and a 512 x 256 size matrix. Saline water bags were used to enhance the signal between the neck and the thorax. Sites of brachial plexus compromise were demonstrated. Our technique with 3-D reconstruction increased the definition of brachial plexus pathology. The increased anatomical definition enabled the vascular surgeons and neurosurgeons to improve patient care. Brachial plexus in vivo anatomy as displayed by MRI, magnetic resonance angiography (MRA), and 3-D reconstruction offered an opportunity to augment the teaching of clinical anatomy to medical students and health professionals. Selected case presentations (bodybuilder, anomalous muscle, fractured clavicle, thyroid goiter, silicone breast implant rupture, and cervical rib) demonstrated compromise of the brachial plexus displayed by MRI. The MRI and 3-D reconstruction techniques, demonstrating the bilateral landmark anatomy, increased the definition of the clinical anatomy and resulted in greater knowledge of patient care management.

    Derangements of glucose metabolism are common among critically ill patients. Critical illness- associated hyperglycemia (CIAH) is characterized by raised blood glucose levels in association with an acute event that is reversible after resolution of the underlying disease. CIAH has many causes, such as changes in counter-regulatory hormone status, release of sepsis mediators, insulin resistance, drugs and nutritional factors. It is associated with increased mortality risk. This association appears to be strongly influenced by diabetes mellitus as a comorbidity, suggesting the need for an accurate individualization of glycemic targets according to baseline glycemic status. Hypoglycemia is also very common in this clinical context and it has a negative prognostic impact. Many studies based on intensive insulin treatment protocols targeting normal blood glucose values have in fact documented both an increased incidence of hypoglycemia and an increased mortality risk. Finally, glycemic control in the ICU is made even more complex in the presence of acute kidney injury. On one hand, there is in fact a reduction of both the renal clearance of insulin and of gluconeogenesis by the kidney. On the other hand, the frequent need for renal replacement therapy (dialysis / hemofiltration) may result in an energy intake excess, under the form of citrate, lactate and glucose in the dialysate/reinfusion fluids. With regard to the possible renal protective effects afforded by intensive glycemic control protocols, the presently available evidence does not support a reduction in the incidence of AKI and/or the need for RRT with this approach, when compared with standard glucose control. Thus, the most recent guidelines now suggest higher blood glucose targets (<180 mg/dl or 140-180 mg/dl) than in the past (80-110 mg/dl). Albeit with limited evidence, it seems reasonable to extend these indications also to patients with AKI in the intensive care unit. Further studies are needed in order

    Brachial plexus neuritis is reportedly caused by various factors; however, it has not been described in association with Streptococcus agalactiae. This is a case report of a patient diagnosed with brachial plexus neuritis associated with pyogenic arthritis of the shoulder. A 57-year-old man visited the hospital complaining of sudden weakness and painful swelling of the left arm. The diagnosis was pyogenic arthritis of the left shoulder, and the patient was treated with open irrigation and debridement accompanied by intravenous antibiotic therapy. S. agalactiae was isolated from a wound culture, and an electrodiagnostic study showed brachial plexopathy involving the left upper and middle trunk. Nine weeks after onset, muscle strength improved in most of the affected muscles, and an electrodiagnostic study showed signs of reinnervation. In conclusion, S. agalactiae infection can lead to various complications including brachial plexus neuritis. PMID:25229037

    Little is known about the relation between fornix injury and memory impairment in diffuse axonal injury (DAI). In the current study, we attempted to investigate fornix injury in patients with memory impairment following DAI, using diffusion tensor imaging (DTI). Nine patients with DAI and nine age-and sex-matched control subjects were recruited. The DTIs were acquired using a sensitivity-encoding head coil on a 1.5 T. Five regions of interest (ROI) were drawn manually on a color fractional anisotropy (FA) map: two ROIs for each column, one ROI for the body, and two ROIs for each crus. The FA and apparent diffusion coefficient (ADC) were measured in each of the ROIs. Cognitive function was evaluated using the Memory Assessment Scale, Wechsler Intelligence Scale, and Mini-Mental State Exam. In the DAI group, the FA value in the fornix body was significantly decreased compared with that of the control group. In contrast, we did not find significant differences in the column and crus of the fornix. Among all of the cognitive function scales, only the Memory Assessment Scale scores were significantly correlated with the FA values of the fornix body in the DAI group. We found that memory impairment in patients with DAI is closely related to neuronal injury of the fornix body among the three fornix regions that we assessed. DTI could be useful in the evaluation of patients with memory impairment following DAI. PMID:20555158

    Objective To investigate the clinical characteristics of patients involved in road traffic accidents according to the New Injury Severity Score (NISS). Methods In this study, medical records of 1,048 patients admitted at three hospitals located in different regions between January and December 2014 were retrospectively reviewed. Only patients who received inpatient treatments covered by automobile insurance during the period were included. Accidents were classified as pedestrian, driver, passenger, motorcycle, or bicycle; and the severity of injury was assessed by the NISS. Results The proportion of pedestrian traffic accident (TA) was the highest, followed by driver, passenger, motorcycle and bicycle TA. The mean NISS was significantly higher in pedestrian and motorcycle TAs and lower in passenger TA. Analysis of differences in mean hospital length of stay (HLS) according to NISS injury severity revealed 4.97±4.86 days in the minor injury group, 8.91±5.93 days in the moderate injury group, 15.46±11.16 days in the serious injury group, 24.73±17.03 days in the severe injury group, and 30.86±34.03 days in the critical injury group (p<0.05). Conclusion The study results indicated that higher NISS correlated to longer HLS, fewer home discharges, and increasing mortality. Specialized hospitals for TA patient rehabilitation are necessary to reduce disabilities in TA patients. PMID:27152279

    Mismatch negativity is generated automatically, and is an early monitoring indicator of neuronal integrity impairment and functional abnormality in patients with brain injury, leading to decline of cognitive function. Antipsychotic medication cannot affect mismatch negativity. The present study aimed to explore the relationships of mismatch negativity with neurocognition, daily life and social functional outcomes in patients after brain injury. Twelve patients with traumatic brain injury and 12 healthy controls were recruited in this study. We examined neurocognition with the Wechsler Adult Intelligence Scale-Revised China, and daily and social functional outcomes with the Activity of Daily Living Scale and Social Disability Screening Schedule, respectively. Mismatch negativity was analyzed from electroencephalogram recording. The results showed that mismatch negativity amplitudes decreased in patients with traumatic brain injury compared with healthy controls. Mismatch negativity amplitude was negatively correlated with measurements of neurocognition and positively correlated with functional outcomes in patients after traumatic brain injury. Further, the most significant positive correlations were found between mismatch negativity in the fronto-central region and measures of functional outcomes. The most significant positive correlations were also found between mismatch negativity at the FCz electrode and daily living function. Mismatch negativity amplitudes were extremely positively associated with Social Disability Screening Schedule scores at the Fz electrode in brain injury patients. These experimental findings suggest that mismatch negativity might efficiently reflect functional outcomes in patients after traumatic brain injury. PMID:26170824

    Infections are the leading cause of morbidity and mortality among burn-injury patients. Even in the absence of documented infection, antibiotics are often given to burn-injury patients at the beginning of treatment, an empirical measure in response to signs and symptoms of infection. The choice of antimicrobial therapy for these patients should be based on technical criteria, based on laboratory findings, at the risk of further increasing antimicrobial resistance levels.

    Objective To investigate the incidence of corpus callosum injury (CCI) in patients with mild traumatic brain injury (TBI) using brain MRI. We also performed a review of the clinical characteristics associated with this injury. Methods A total of 356 patients in the study were diagnosed with TBI, with 94 patients classified as having mild TBI. We included patients with mild TBI for further evaluation if they had normal findings via brain computed tomography (CT) scans and also underwent brain MRI in the acute phase following trauma. As assessed by brain MRI, CCI was defined as a high-signal lesion in T2 sagittal images and a corresponding low-signal lesion as determined by axial gradient echo (GRE) imaging. Based on these criteria, we divided patients into two groups for further analysis : Group I (TBI patients with CCI) and Group II (TBI patients without CCI). Results A total of 56 patients were enrolled in this study (including 16 patients in Group I and 40 patients in Group II). Analysis of clinical symptoms revealed a significant difference in headache severity between groups. Over 50% of patients in Group I experienced prolonged neurological symptoms including dizziness and gait disturbance and were more common in Group I than Group II (dizziness : 37 and 12% in Groups I and II, respectively; gait disturbance : 12 and 0% in Groups I and II, respectively). Conclusion The incidence of CCI in patients with mild TBI was approximately 29%. We suggest that brain MRI is a useful method to reveal the cause of persistent symptoms and predict clinical prognosis. PMID:26361529

    The brachial plexus is an important nervous system structure. It can be injured during the perinatal period and by postnatal damage. The goal of this study was to assess human fetal brachial plexus variability. A total of 220 brachial plexuses were surgically prepared from 110 human fetuses aged 14-32 weeks of fetal life (50 females and 60 males) ranging in CRL from 80 to 233 mm. The study incorporated the following methods: dissectional and anthropological, digital image acquisition, digital image processing using Image J and GIMP software, and statistical methods (Statistica 9.0). Symmetry and sexual dimorphism were examined. Anomalies of the brachial plexuses were observed in 117 (53.18 %) cases. No sexual dimorphism was found. It was observed that cord variations occurred more often on the left side. Division variants (33.64 %) occurred most often, but also cords (18.18 %) as well as root nerves and terminal ramifications (15.90 %) were found. Trunk anomalies were rare and occurred in only 5.45 % of plexuses. Three height types of median nerve roots in combination with the nerve were distinguished. In one-third of cases, median nerve root connections were found below the axillary fossa and even half in the proximal part of the humerus. In conclusion, the brachial plexus was characterized for anatomical structural variability. Most often division and cord variations were observed. Anomalies occurred regardless of sex or body side except for cord variants. Brachial plexus variation recognition is significant from the neurosurgical and traumatological point of view.

    Since Monro published his observations on the nature of the contents of the intracranial space in 1783, there has been investigation of the unique relationship between the contents of the skull and the intracranial pressure (ICP). This is particularly true following traumatic brain injury (TBI), where it is clear that elevated ICP due to the underlying pathological processes is associated with a poorer clinical outcome. Consequently, there is considerable interest in monitoring and manipulating ICP in patients with TBI. The two techniques most commonly used in clinical practice to monitor ICP are via an intraventricular or intraparenchymal catheter with a microtransducer system. Both of these techniques are invasive and are thus associated with complications such as hemorrhage and infection. For this reason, significant research effort has been directed toward development of a non-invasive method to measure ICP. The principle aims of ICP monitoring in TBI are to allow early detection of secondary hemorrhage and to guide therapies that limit intracranial hypertension (ICH) and optimize cerebral perfusion. However, information from the ICP value and the ICP waveform can also be used to assess the intracranial volume–pressure relationship, estimate cerebrovascular pressure reactivity, and attempt to forecast future episodes of ICH.

    Background and Purpose Imaging studies of traumatic brain injury demonstrate that the cerebellum is often affected. We aim to examine fractional anisotropy alteration in acute-phase mild traumatic brain injury patients in cerebellum-related white matter tracts. Materials and Methods This prospective study included 47 mild traumatic brain injury patients in the acute stage and 37 controls. MR imaging and neurocognitive tests were performed in patients within 7 days of injury. White matter integrity was examined by using diffusion tensor imaging. We used three approaches, tract-based spatial statistics, graphical-model-based multivariate analysis, and region-of-interest analysis, to detect altered cerebellar white matter integrity in mild traumatic brain injury patients. Results Results from three analysis methods were in accordance with each other, and suggested fractional anisotropy in the middle cerebellar peduncle and the pontine crossing tract was changed in the acute-phase mild traumatic brain injury patients, relative to controls (adjusted p-value < 0.05). Higher fractional anisotropy in the middle cerebellar peduncle was associated with worse performance in the fluid cognition composite (r = -0.289, p-value = 0.037). Conclusion Altered cerebellar fractional anisotropy in acute-phase mild traumatic brain injury patients is localized in specific regions and statistically associated with cognitive deficits detectable on neurocognitive testing.

    Objective. There is increasing evidence of adverse outcomes associated with blood transfusions for adult traumatic brain injury patients. However, current evidence suggests that pediatric traumatic brain injury patients may respond to blood transfusions differently on a vascular level. This study examined the influence of blood transfusions and anemia on the outcome of pediatric traumatic brain injury patients. Design. A retrospective cohort analysis of severe pediatric traumatic brain injury (TBI) patients was undertaken to investigate the association between blood transfusions and anemia on patient outcomes. Measurements and Main Results. One hundred and twenty patients with severe traumatic brain injury were identified and included in the analysis. The median Glasgow Coma Scale (GCS) was 6 and the mean hemoglobin (Hgb) on admission was 115.8 g/L. Forty-three percent of patients (43%) received at least one blood transfusion and the mean hemoglobin before transfusion was 80.1 g/L. Multivariable regression analysis revealed that anemia and the administration of packed red blood cells were not associated with adverse outcomes. Factors that were significantly associated with mortality were presence of abusive head trauma, increasing PRISM score, and low GCS after admission. Conclusion. In this single centre retrospective cohort study, there was no association found between anemia, blood transfusions, and hospital mortality in a pediatric traumatic brain injury patient population.

    Well-differentiated human cancers share transcriptional programmes with the normal tissue counterparts from which they arise. These programmes broadly influence cell behaviour and function and are integral modulators of malignancy. Here, we show that the master regulator of motile ciliogenesis, FOXJ1, is highly expressed in cells along the ventricular surface of the human brain. Strong expression is present in cells of the ependyma and the choroid plexus as well as in a subset of cells residing in the subventricular zone. Expression of FOXJ1 and its transcriptional programme is maintained in many well-differentiated human tumours that arise along the ventricle, including low-grade ependymal tumours and choroid plexus papillomas. Anaplastic ependymomas as well as choroid plexus carcinomas show decreased FOXJ1 expression and its associated ciliogenesis programme genes. In ependymomas and choroid plexus tumours, reduced expression of FOXJ1 and its ciliogenesis programme are markers of poor outcome and are therefore useful biomarkers for assessing these tumours. Transitions in ciliogenesis define distinct differentiation states in ependymal and choroid plexus tumours with important implications for patient care.

    Introduction: The brachial plexus block is a commonly performed procedure in the anesthetic practice today. It is performed for analgesia as well as anesthesia for upper limb procedures. It has been used for amputation and replantation surgeries of the upper limb. Case presentation: We present the case of a 68-year-old gentleman who had brachial plexus block at supraclavicular and interscalene levels as the sole anesthetic for undergoing above elbow amputation. He was deemed to be very high risk for a general anesthetic as he suffered from severe chronic obstructive pulmonary disease (COPD) and a very poor exercise tolerance (NYHA Class III). The supraclavicular brachial plexus block was supplemented with an interscalene brachial plexus block due to inadequate surgical anesthesia encountered with the former. The procedure was successfully completed under regional anesthesia. Conclusions: The brachial plexus block can be performed at different levels in the same patient to achieve desired results, while employing sound anatomical knowledge and adhering to the maximum safe dose limit of the local anesthetic.

    Full-thickness muscle biopsies have been taken from patients with severe disabling chronic constipation that has not responded to conservative measures. Assessment by neurohistochemical techniques has revealed that a range of neuronal dysplasias of the myenteric plexus are responsible in many cases; these include aganglionosis (Hirschsprung's disease), hypoganglionosis and hyperganglionosis. In cases considered unlikely to be Hirschsprung's disease on clinical grounds, the procedure used has often been anorectal myectomy; this has not only provided tissue for diagnosis but has also been of therapeutic value in most cases of hypoganglionosis and some cases reported as 'normal'.

    2010-01-01

    Background The pre-hospital assessment of a blunt trauma is difficult. Common triage tools are the mechanism of injury (MOI), vital signs, and anatomic injury (AI). Compared to the other tools, the clinical assessment of anatomic injury is more subjective than the others, and, hence, more dependent on the skills of the personnel. The aim of the study was to estimate whether the training and qualifications of the personnel are associated with the accuracy of prediction of anatomic injury and the completion of pre-hospital procedures indicated by local guidelines. Methods Adult trauma patients met by a trauma team at Helsinki University Trauma Centre during a 12-month period (n = 422) were retrospectively analysed. To evaluate the accuracy of prediction of anatomic injury, clinically assessed pre-hospital injuries in six body regions were compared to injuries assessed at hospital in two patient groups, the patients treated by pre-hospital physicians (group 1, n = 230) and those treated by paramedics (group 2, n = 190). Results The groups were comparable in respect to age, sex, and MOI, but the patients treated by physicians were more severely injured than those treated by paramedics [ISS median (interquartile range) 16 (6-26) vs. 6 (2-10)], thus rendering direct comparison of the groups ineligible. The positive predictive values (95% confidence interval) of assessed injury were highest in head injury [0,91 (0,84-0,95) in group 1 and 0,86 (0,77-0,92) in group 2]. The negative predictive values were highest in abdominal injury [0,85 (0,79-0,89) in group 1 and 0,90 (0,84-0,93) in group 2]. The measurements of agreement between injuries assessed pre- and in-hospitally were moderate in thoracic and extremity injuries. Substantial kappa values (95% confidence interval) were achieved in head injury, 0,67 (0,57-0,77) in group 1 and 0,63 (0,52-0,74) in group 2. The rate of performing the pre-hospital procedures as indicated by the local instructions was 95-99%, except for

    The objective of this study was to evaluate the incidence, types and severity of burn injuries, including sites involved, morbidities, operative procedures, and their outcomes, to prevent or reduce the frequency and morbidity of such injuries in epileptic patients. This retrospective study was conducted at our centre between February 2008 and January 2012. The study included 54 patients who sustained burn injuries due to epileptic seizures, accounting for 1.3% of all burn admissions. All patients, irrespective of the severity of their injuries, were admitted to our centre, assessed, treated and educated regarding specific preventive measures. All study data were evaluated from patient medical records. Causes of burn injury were as follows: scald burns (30), contact with hot surfaces (12), electrical burns in the bathroom (6), and flame burns (6). Second degree burns were the most common (18 out of 54 patients) and third degree burns were the least common. Upper limb and trunk were the most common sites involved (36 out of 54 patients). Thirty patients required surgical intervention whereas the remainder was conservatively managed. Most of the injuries occurred in the age group between 30-37 years. Injuries occurred predominantly in females [42 females, 12 males; F:M=3.5:1]. The study revealed that patients with epilepsy should be categorized as a high risk group considering the sudden and unpredictable attack of epileptic seizures leading to loss of consciousness and accidental burn injuries. Early surgical intervention and targeting of all epileptic patients for education and instituting the specific preventive measures gives good outcomes. PMID:26170789

    The aim of the study was to determine the frequency of different injuries caused by penetrating chest traumas, and also the cause and type of trauma and its accompanying injuries. This is a cross-sectional descriptive study, carried out on all patients referred to the emergency room of Shahid Bahonar Hospital, Kerman, from March 2000 to September 2008, due to penetrating chest trauma. The required information including age, sex, cause of trauma, type and site of injury, and accompanying injury was obtained and used to fill out a questionnaire and then was analyzed. 828 patients were included in the study; most of them were in the age range of 20-29. Of the patients, 97.6 % were males. The most frequent cause of trauma was stabbing, and the most frequent injuries following the trauma were pneumothorax and hemothorax. Orthopedic trauma was the most frequent accompanying injury. The most commonly used diagnostic method was plain chest radiography. In 93 % of the patients, the chest tube was placed and thoracotomy was performed for 97 % of the patients. Shahid Bahonar Hospital is a referral Trauma Centre and treats large number of chest trauma patients. Most patients need only chest tube placement as a definitive treatment. PMID:26246700

    Background The interscalene brachial plexus block is widely used for pain control and anesthetic purposes during shoulder arthroscopic surgeries and surgeries of the upper extremities. However, it is known that interscalene brachial plexus block is not appropriate for upper limb surgeries because it does not affect the lower trunk (C8-T1, ulnar nerve) of the brachial plexus. Methods A low approach, ultrasound-guided interscalene brachial plexus block (LISB) was performed on twenty-eight patients undergoing surgery of the upper extremities. The patients were assessed five minutes and fifteen minutes after the block for the degree of block in each nerve and muscle as well as for any complications. Results At five minutes and fifteen minutes after the performance of the block, the degree of the block in the ulnar nerve was found to be 2.8 ± 2.6 and 1.1 ± 1.8, respectively, based on a ten-point scale. Motor block occurred in the median nerve after fifteen minutes in 26 of the 28 patients (92.8%), and in all of the other three nerves in all 28 patients. None of the patients received additional analgesics, and none experienced complications. Conclusions The present study confirmed the achievement of an appropriate sensory and motor block in the upper extremities, including the ulnar nerve, fifteen minutes after LISB, with no complications.

    Herpes zoster, commonly known as shingles, is an infectious viral disease characterized by painful, unilateral skin blisters occurring in specific sensory dermatomes. Motor paresis is reported in 0.5% to 5% of patients. Although the mechanism of zoster paresis is still unclear, the virus can spread from the dorsal root ganglia to the anterior horn cell or anterior spinal nerve roots. It rarely involves the brachial plexus. We report a case of brachial plexitis following herpes zoster infection in which pathological lesions were diagnosed using brachial plexus magnetic resonance imaging and treated with ultrasound-guided perineural corticosteroid injection.

    The choroid plexus, an epithelial-based structure localized in the brain ventricle, is the major component of the blood-cerebrospinal fluid barrier. The choroid plexus produces the cerebrospinal fluid and regulates the components of the cerebrospinal fluid. Abnormal choroid plexus function is associated with neurodegenerative diseases, tumor formation in the choroid plexus epithelium, and hydrocephaly. In this study, we used zebrafish (Danio rerio) as a model system to understand the genetic components of choroid plexus development. We generated an enhancer trap line, Et(cp:EGFP)sj2, that expresses enhanced green fluorescent protein (EGFP) in the choroid plexus epithelium. Using immunohistochemistry and fluorescent tracers, we demonstrated that the zebrafish choroid plexus possesses brain barrier properties such as tight junctions and transporter activity. Thus, we have established zebrafish as a functionally relevant model to study choroid plexus development. Using an unbiased approach, we performed a forward genetic dissection of the choroid plexus to identify genes essential for its formation and function. Using Et(cp:EGFP)sj2, we isolated 10 recessive mutant lines with choroid plexus abnormalities, which were grouped into five classes based on GFP intensity, epithelial localization, and overall choroid plexus morphology. We also mapped the mutation for two mutant lines to chromosomes 4 and 21, respectively. The mutants generated in this study can be used to elucidate specific genes and signaling pathways essential for choroid plexus development, function, and/or maintenance and will provide important insights into how these genetic mutations contribute to disease.

    Objective To assess the rate and risk factors for position-related injury in robotic gynecologic surgery. Methods A prospective database from 12/2006 to 1/2014 of all planned robotic gynecologic procedures was retrospectively reviewed for patients who experienced neurologic injury, musculoskeletal injury, or vascular compromise related to patient positioning in the operating room. Analysis was performed to determine risk-factors and incidence for position-related injury. Results Of the 831 patients who underwent robotic surgery during the study time period, only 7(0.8%) experienced positioning-related injury. The injuries included minor head contusions (n=3), two lower extremity neuropathies (n=2), brachial plexus injury (n=1) and one large subcutaneous ecchymosis on the left flank and thigh (n=1). There were no long term sequelae from the positioning-related injuries. The only statistically significant risk factor for positioning-related injury was prior abdominal surgery (p = 0.05). There were no significant associations between position-related injuries and operative time (P = 0.232), body mass index (P=0.847), age (p = 0.152), smoking history (P = 0.161), or medical comorbidities (P = 0.229 – 0.999). Conclusions The incidence of position-related injury among women undergoing robotic surgery was extremely low (0.8%). Due to the low incidence we were unable to identify modifiable risk factors for position-related injury following robotic surgery. A standardized, team-oriented approach may significantly decrease position-related injuries following robotic gynecologic surgery. PMID:25449565

    Introduction Dyschloremia is common in critically ill patients, although its impact has not been well studied. We investigated the epidemiology of dyschloremia and its associations with the incidence of acute kidney injury and other intensive care unit outcomes. Material and Methods This is a single-center, retrospective cohort study at Mayo Clinic Hospital—Rochester. All adult patients admitted to intensive care units from January 1st, 2006, through December 30th, 2012 were included. Patients with known acute kidney injury and chronic kidney disease stage 5 before intensive care unit admission were excluded. We evaluated the association of dyschloremia with ICU outcomes, after adjustments for the effect of age, gender, Charlson comorbidity index and severity of illness score. Results A total of 6,025 patients were enrolled in the final analysis following the implementation of eligibility criteria. From the cohort, 1,970 patients (33%) developed acute kidney injury. Of the total patients enrolled, 4,174 had a baseline serum chloride. In this group, 1,530 (37%) had hypochloremia, and 257 (6%) were hyperchloremic. The incidence of acute kidney injury was higher in hypochloremic and hyperchloremic patients compared to those with a normal serum chloride level (43% vs.30% and 34% vs. 30%, respectively; P < .001). Baseline serum chloride was lower in the acute kidney injury group vs. the non-acute kidney injury group [100 mmol/L (96–104) vs. 102 mmol/L (98–105), P < .0001]. In a multivariable logistic regression model, baseline serum chloride of ≤94 mmol/L found to be independently associated with the risk of acute kidney injury (OR 1.7, 95% CI 1.1–2.6; P = .01). Discussion Dyschloremia is common in critically ill patients, and severe hypochloremia is independently associated with an increased risk of development of acute kidney injury. PMID:27490461

    OBJECT The objective of this study was to report the results of pronator quadratus (PQ) motor branch transfers to the extensor carpi radialis brevis (ECRB) motor branch to reconstruct wrist extension in C5-8 root lesions of the brachial plexus. METHODS Twenty-eight patients, averaging 24 years of age, with C5-8 root injuries underwent operations an average of 7 months after their accident. In 19 patients, wrist extension was impossible at baseline, whereas in 9 patients wrist extension was managed by activating thumb and wrist extensors. When these 9 patients grasped an object, their wrist dropped and grasp strength was lost. Wrist extension was reconstructed by transferring the PQ motor to the ECRB motor branch. After surgery, patients were followed for at least 12 months, with final follow-up an average of 22 months after surgery. RESULTS Successful reinnervation of the ECRB was demonstrated in 27 of the 28 patients. In 25 of the patients, wrist extension scored M4, and in 2 it scored M3. CONCLUSIONS In C5-8 root injuries, wrist extension can be predictably reconstructed by transferring the PQ motor branch to reinnervate the ECRB. PMID:26430841

    The management of pregnant patients with traumatic brain injury is challenging. A multidisciplinary team approach is mandatory, and management should be individualized according to the type and extent of injury, maternal status, gestational age, and fetal status. We report a 27-year-old term primigravida presenting after head injury with Glasgow coma scale score 11 and anisocoria. Depressed temporal bone fracture and acute epidural hematoma were diagnosed, necessitating an urgent neurosurgery. Her fetus was viable with no signs of distress and no detected placental abnormalities. Cesarean delivery was performed followed by craniotomy in the same setting under general anesthesia with good outcome of the patient and her baby. PMID:25829914

    Early mobilization is of importance for improving long-term outcome for patients after severe acquired brain injury. A limiting factor for early mobilization by head-up tilt is orthostatic intolerance. The purpose of the present study was to examine cerebral autoregulation in patients with severe acquired brain injury and a low level of consciousness. Fourteen patients with severe acquired brain injury and orthostatic intolerance and fifteen healthy volunteers were enrolled. Blood pressure was evaluated by pulse contour analysis, heart rate and RR-intervals were determined by electrocardiography, middle cerebral artery velocity was evaluated by transcranial Doppler, and near-infrared spectroscopy determined frontal lobe oxygenation in the supine position and during head-up tilt. Cerebral autoregulation was evaluated as the mean flow index calculated as the ratio between middle cerebral artery mean velocity and estimated cerebral perfusion pressure. Patients with acquired brain injury presented an increase in mean flow index during head-up tilt indicating impaired autoregulation (P < 0.001). Spectral analysis of heart rate variability in the frequency domain revealed lower magnitudes of ~0.1 Hz spectral power in patients compared to healthy controls suggesting baroreflex dysfunction. In conclusion, patients with severe acquired brain injury and orthostatic intolerance during head-up tilt have impaired cerebral autoregulation more than one month after brain injury. PMID:27168188

    Background: Older people are at increased risk of traumatic spinal cord injury from falls. We evaluated the impact of older age (≥ 70 yr) on treatment decisions and outcomes. Methods: We identified patients with traumatic spinal cord injury for whom consent and detailed data were available from among patients recruited (2004–2013) at any of the 31 acute care and rehabilitation hospitals participating in the Rick Hansen Spinal Cord Injury Registry. Patients were assessed by age group (< 70 v. ≥ 70 yr). The primary outcome was the rate of acute surgical treatment. We used bivariate and multivariate regression models to assess patient and injury-related factors associated with receiving surgical treatment and with the timing of surgery after arrival to a participating centre. Results: Of the 1440 patients included in our study cohort, 167 (11.6%) were 70 years or older at the time of injury. Older patients were more likely than younger patients to be injured by falling (83.1% v. 37.4%; p < 0.001), to have a cervical injury (78.0% v. 61.6%; p = 0.001), to have less severe injuries on admission (American Spinal Injury Association Impairment Scale grade C or D: 70.5% v. 46.9%; p < 0.001), to have a longer stay in an acute care hospital (median 35 v. 28 d; p < 0.005) and to have a higher in-hospital mortality (4.2% v. 0.6%; p < 0.001). Multivariate analysis did not show that age of 70 years or more at injury was associated with a decreased likelihood of surgical treatment (adjusted odds ratio [OR] 0.48, 95% confidence interval [CI] 0.22–1.07). An unplanned sensitivity analysis with different age thresholds showed that a threshold of 65 years was associated with a decreased chance of surgical treatment (OR 0.39, 95% CI 0.19–0.80). Older patients who underwent surgical treatment had a significantly longer wait time from admission to surgery than younger patients (37 v. 19 h; p < 0.001). Interpretation: We found chronological age to be a factor influencing

    The Human Tissue Act 2004 and Mental Capacity Act 2005 resulted in a change in the management of needlestick injuries sustained from incapacitated patients. It appears unlawful to test for blood-borne viruses without a patient's consent for the sole benefit of the healthcare worker. This survey of intensive care units within England, Wales and Northern Ireland investigated how needlestick injuries from incapacitated patients had been managed within the previous year. Of the 225 intensive care units surveyed, 99 (44%) responded. Sixty-two (62.6%) reported a needlestick injury to a healthcare worker from an incapacitated patient. Thirty-six (64.3%) patients were tested for blood-borne viruses without consent. Sixteen (25.8%) patients tested positive for blood-borne viruses. Only 19 (30.6%) healthcare workers took post-exposure prophylaxis following the injury. These results show that needlestick injuries from incapacitated patients are common and that the majority of patients were tested for blood-borne viruses without consent. PMID:21198483

    We conducted a preliminarily study on the clinical characteristics of chronic lung injury (CLI) in patients with non-Hodgkin lymphoma (NHL) after CHOP chemotherapy and observed the effects of this injury on CHOP treatment efficacy. Sixty patients who were diagnosed as NHL and received CHOP chemotherapy in hospital were enrolled for this clinical trial. CLI was assessed by clinical symptoms and computed tomography (CT) scan conducted before and after chemotherapy. The effect of CLI on the efficacy of CHOP chemotherapy in patients with NHL was evaluated by comparing treatment response and recurrence rate to patients with no signs of lung injury. Our CT scans revealed multiple signs of CLI in 35 patients (56.67 %), such as pulmonary diffuse, limited infiltration shadow or ground glass-like changes. Among them, 23 patients (38.33 %) showed bilateral diffuse lung injury and 12 (20.00 %) showed topical lung injury. Most patients suffering from 6 to 12 months delayed recurrence exhibited signs of CLI. The inflammatory response of CLI may increase the risk of disease progression and recurrence. Therefore, early diagnosis and intervention, which play a positive role in the clinical treatment and the long-term efficacy, are critical for patients with NHL. PMID:25201066

    Progressive hemorrhagic injury (PHI) can be divided into coagulopathy-related PHI and normal coagu- lation PHI. Coagulation disorders after traumatic brain injuries can be included in trauma-induced coagulopathy (TIC). Some studies showed that TIC is associated with PHI and increases the rates of disability and mortality. In this review, we discussed some mechanisms in TIC, which is of great importance in the development of PHI, including tissue factor (TF) hypothesis, protein C pathway and thrombocytopenia. The main mechanism in the relation of TIC to PHI is hypocoagulability. We also reviewed some coagulopathy parameters and proposed some possible risk factors, predictors and therapies. PMID:27321300

    Objectives: Hypermobility may be a risk factor for musculoskeletal injuries during sports participation. However, we have seen a low incidence of chondral injuries requiring treatment in patients undergoing medial patellofemoral ligament (MPFL) reconstruction for patellofemoral instability. It is unknown if patients with ligamentous laxity, who are at an increased risk for patellofemoral instability, are somewhat protected from chondral injury. We hypothesize in patients undergoing MPFL reconstruction for patellofemoral instability, patients with ligamentous laxity will be less likely to have chondral defects requiring surgical intervention. Methods: 171 patients (32 male, 139 female) average age 22 years (range 11-57) with patellofemoral instability were rated with the Beighton-Horan (BH) scale for constitutional ligamentous laxity (0-9). Preoperative MRIs were evaluated (chondral injury present/absent, size of chondral injury, Outerbridge grade) and intra-operative arthroscopic findings noted (chondral injury present/absent, size of chondral injury, Outerbridge grade, surgical intervention yes/no, type of surgical intervention) of 79 non-lax (BH<6) and 92 ligamentously lax patients (BH≥6) (LAX) undergoing MPFL reconstruction. Anatomic measurements were documented for each patient including: tibial tubercle-trochlear groove (TT-TG) distance, Caton-Deschamps (C/D) ratio for patellar height, and the Dejour classification of trochlear dysplasia. Surgical interventions included chondroplasty, microfracture, particulated juvenile cartilage implantation (DeNovo, Zimmer, Warsaw, IN), osteochondral fracture fixation or osteochondral allograft transplantation (OATS). Results: 58/171 (33.9%) required a surgical intervention for a chondral defect: chondroplasty 29/58 (50%), microfracture 16/58 (27.6%), particulated juvenile cartilage implantation 18/58 (31%), osteochondral fracture fixation 2/58 (3.5%), and OATS 2/58 (3.5%).

    2015-07-01

    OBJECT Choroid plexus papillomas (CPPs) are rare neoplasms, often found in the atrium of the lateral ventricle of infants, and cause overproduction hydrocephalus. The extensive vascularity and medially located blood supply of these tumors, coupled with the young age of the patients, can make prevention of blood loss challenging. Preoperative embolization has been advocated to reduce blood loss and prevent the need for transfusion, but this mandates radiation exposure and the additional risks of vessel injury and stroke. For these reasons, the authors present their experience using the superior parietal lobule approach to CPPs of the atrium without adjunct therapy. METHODS A retrospective review was conducted of all children who presented to Columbia University/Morgan Stanley Children's Hospital of New York with a CPP in the atrium of the lateral ventricle and who underwent surgery using a superior parietal lobule approach without preoperative embolization. RESULTS Nine children were included, with a median age of 7 months. There were no perioperative complications or new neurological deficits. All patients had intraoperative blood loss of less than 100 ml, with a mean minimum hematocrit of 26.9% (range 19.6%-36.2%). No patients required a blood transfusion. The median follow-up was 39 months, during which time no patient demonstrated residual or recurrent tumor on MRI, nor did any have an increase in ventricular size or require CSF diversion. CONCLUSIONS The superior parietal lobule approach is safe and effective for very young children with CPPs in the atrium of the lateral ventricle. The results suggest that preoperative embolization is not essential to avoid transfusion or achieve overall good outcomes in these patients. This management strategy avoids radiation exposure and the additional risks associated with embolization. PMID:25860983

    2000-07-01

    An interscalene block of the brachial plexus was combined with general anaesthesia for repair of a complex chronic lesion of the shoulder. The localisation of the plexus with electro-stimulation and the injection of Bupivacain 0.5% were accomplished easily and without painful sensations. 48 hours later the block was still partially present. Paraesthesia and a sensory and motor innervation deficit affected mainly the dorsal fascicle, but also areas innervated by the median and lateral fascicles. The deficit did not completely disappear for 18 month. The cause could have been due to direct traumatisation during blockade or operation, toxic action of the injected substance (Bupivacain 0.5%, 30 ml), distension of the plexus, a cervical syndrome or an aseptic plexitis, although a definite determination is not possible. However, the pattern of the lesion and the lack of pain during localisation of the plexus and injection favour traumatisation during the acromioplasty. PMID:10969388

    Background An anterior cruciate ligament (ACL) graft rupture or a primary ACL injury in the contralateral knee is one of the greatest concerns of patients following primary anterior cruciate ligament reconstruction (ACLR). Our study describes the epidemiology and presence of concomitant meniscal injuries of patients with a graft rupture following primary ACLR or a primary rupture of the contralateral ACL following primary ACLR of the ipsilateral knee. Methods We reviewed the medical records of 42 patients who underwent a second ACLR. ACLR was performed using the ipsilateral semitendinosus and gracilis autograft. Variables extracted included the presence of concomitant MM and LM injuries intra-operatively, the patients’ level of intensity of sport (light, moderate, strenuous), duration of rehabilitation and mechanism of injury (contact, non-contact). Results Twenty-four (57.1%) patients had graft rupture of a previously reconstructed ACL of which 20 (83.3%) were male and 18 (42.9%) patients had a primary ACL tear of the contralateral knee following ACLR of the ipsilateral knee of which 18 (100%) were male. Patient who sustained a graft rupture were younger (29.5 vs. 31.9 years), had a higher body mass index (BMI) (26.42 vs. 25.10 kg/m2) and had a longer time before re-injury (6.18 vs. 4.94 years). Concomitant meniscal injury rates were comparable in both groups and the medial meniscus was injured more often. Conclusions This study describes the demographics of 2nd ACL injuries in the Asian population. Additional studies that investigate the differences in knee anatomy of Asians and Caucasians and their impact on ACL injuries should be performed. PMID:27429958

    The objective of this study is to study the anatomy of lumbar plexus on human fetuses and to establish its morphometric characteristics and differences compared with adults. Twenty lumbar plexus of 10 human fetal cadavers in different gestational ages and genders were dissected. Lumbar spinal nerves, ganglions, and peripheral nerves were exposed. Normal anatomical structure and variations of lumbar plexus were investigated and morphometric analyses were performed. The diameters of lumbar spinal nerves increased from L1 to L4. The thickest nerve forming the plexus was femoral nerve, the thinnest was ilioinguinal nerve, the longest nerve through posterior abdominal wall was iliohypogastric nerve, and the shortest nerve was femoral nerve. Each plexus had a single furcal nerve and this arose from L4 nerve in all fetuses. No prefix or postfix plexus variation was observed. In two plexuses, L1 nerve was in the form of a single branch. Also, in two plexuses, genitofemoral nerve arose only from L2 nerve. Accessory obturator nerve was observed in four plexuses. According to these findings, the morphological pattern of the lumbar plexus in the fetus was found to be very similar to the lumbar plexus in adults. PMID:22696243

    BACKGROUND In our clinical experience we discovered that EEG band power may be correlated with corneal nerve injury in retinoblastoma patients. This study aimed to investigate biomarkers obtained from electroencephalography (EEG) recordings to reflect corneal nerve injury in retinoblastoma patients. MATERIAL AND METHODS Our study included 20 retinoblastoma patients treated at the Department of Ophthalmology, Affiliated Hospital of Weifang Medical University between 2010 and 2014. Twenty normal individuals were included in the control group. EEG activity was recorded continuously with 32 electrodes using standard EEG electrode placement for detecting EEG power. A cornea confocal microscope was used to examine corneal nerve injury in retinoblastoma patients and normal individuals. Spearman rank correlation analysis was used to analyze the correlation between corneal nerve injury and EEG power changes. The sensitivity and specificity of changed EEG power in diagnosis of corneal nerve injury were also analyzed. RESULTS The predominantly slow EEG oscillations changed gradually into faster waves in retinoblastoma patients. The EEG pattern in retinoblastoma patients was characterized by a distinct increase of delta (P<0.01) and significant decrease of theta power P<0.05). Corneal nerves were damaged in corneas of retinoblastoma patients. Corneal nerve injury was positively correlated with delta EEG spectra power and negatively correlated with theta EEG spectra power. The diagnostic sensitivity and specificity by compounding in the series were 60% and 67%, respectively. CONCLUSIONS Changes in delta and theta of EEG appear to be associated with occurrence of corneal nerve injury. Useful information can be provided for evaluating corneal nerve damage in retinoblastoma patients through analyzing EEG power bands. PMID:27592207

    The mortality and morbidity rates of patients with spinal cord injury have decreased greatly. Prior to World War II, few patients survived their acute injuries. Now even severely involved respiratory-dependent patients may return to live in the community. Advanced surgical procedures, when appropriately applied, are decreasing the time of immobility and preventing late spinal deformities. Exciting new developments in basic science research such as the use of thyrotropin-releasing hormone and functional electrical stimulation may alter the whole course of recovery for patients within the foreseeable future. It is likely, however, that the acute management of the patient with spinal cord injury will still demand systematic care by an experienced, multidisciplinary team of professionals. PMID:3945478

Methods: This was a cross-sectional study being performed in Imam Reza Hospital affiliated with Mashhad University of Medical Sciences, Iran between September 2011 and March 2013. We included those patients with extremity blunt and penetrating injuries who were referred for angiography according to standard indications including abnormal distal pulses, complex fracture or dislocation, vascular proximity, fixed hematoma, distal nerve deficit, arterial bruit, thrill and massive soft tissue injuries. Results: During the study period, 148 patients (15 women and 133 men) with a mean age of 31±14.9 (11-82) years were evaluated. The most common cause of injury was motor vehicle accident (127 patients 85%). Angiography indications included abnormal distal pulse examination (124, 83.8%), complex fracture or dislocation (7, 4.7%), near arterial trauma (4, 2.7%), fixed hematoma (3, 2%), nerve damage (1, 0.7%). The angiography was found to be normal in 49 (33.1%) patients. In patients with abnormal angiography findings, 60 (60.6%) had cutoff with distal runoff, 21 (21.2%) had cutoff without runoff, 14 (14.1%) had arterial spasm. Other uncommon findings included active bleeding in 2 patients (2%), pseudoaneurysm in 1 (0.7%) and arteriovenous fistula in 1 (0.7%). Out of 4 patients (2.7%) with vascular proximity, only 1 (0.7%) had abnormal angiography. Conclusion: The most  important  factor in prediction  of result of angiography was distal arterial pulses examination. But these data confirm the low incidence of vascular injury in asymptomatic patients with proximity. So the use of angiography when proximity is the sole indication in an asymptomatic patient with a normal vascular examination should be questioned. PMID:27162860

    Aim of the study This study aims to analyze the clinical manifestations and sequelae of peripheral nerve radiation damage of two cases of cancer patients after radiotherapy at the corresponding sites in clinical practice and to summarize experiences and lesions in order to provide a reference for future tumor radiotherapy. Material and methods Some data of two cases of patients, such as doses of radiotherapy, clinical manifestations and damage occurrence time, were collected and examinations were conducted to define diagnosis. Afterwards, therapies and follow-up were conducted. Results Case 1 (rectal cancer) was diagnosed as mild left lower extremity nerve damage. After the symptomatic treatment, the disease condition was improved, and there was no tumor recurrence sign. Case 2 (breast cancer) was diagnosed as left brachial plexus damage, and left upper extremity movement function was lost completely. While the analgesic treatment was conducted, anti-tumor relevant treatments were being carried out. Conclusions Radiotherapy can cause different extents of radioactive nerve damage. In practice, it is necessary to constantly improve the radiotherapy technology level and actively prevent the occurrence of complications. Once symptoms appear, the diagnosis and treatment should be conducted as early as possible in order to avoid aggravating damage to cause dysfunction and cause lifetime pain to patients.

    In contrast to patients with underlying cancer or chronic disease, injury patients are relatively young, and can be expected to live their natural lifespan if injuries are appropriately treated. Multiple and repeated diagnostic scans might be performed in these patients during admission. Nevertheless, radiation exposure in injury patients has been overlooked and underestimated because of the emergent nature of such situations. Therefore, we tried to assess the cumulative effective dose (cED) of injury patients in the emergency department. We included patients who visited the emergency department (ED) of a single tertiary hospital due to injury between February 2010 and February 2011. The cED for each patient was calculated and compared across age, sex and injury mechanism. A total of 11,676 visits (mean age: 28.0 years, M:F = 6,677:4,999) were identified. Although CT consisted of only 7.8% of total radiologic examinations (n=78,025), it accounted for 87.1% of the total cED. The mean cED per visit was 2.6 mSv. A significant difference in the cED among injury mechanisms was seen (p<0.001) and patients with traffic accidents and fall down injuries showed relatively high cED values. Hence, to reduce the cED of injury patients, an age-, sex- and injury mechanism-specific dose reduction strategy should be considered. PMID:24386427

    Little is known about injury of the arcuate fasciculus (AF) in patients with mild traumatic brain injury (TBI). We investigated injury of the AF in the dominant hemisphere in patients with mild TBI, using diffusion tensor tractography (DTT). We recruited 25 patients with injury of the left AF among 64 right-handed consecutive patients with mild TBI and 20 normal control subjects. DTTs of the left AF were reconstructed, and fractional anisotropy (FA), apparent diffusion coefficient (ADC), and fiber number of the AF were measured. Among 64 consecutive patients, 25 (39%) patients showed injury of the left AF. The patient group showed lower FA value and fiber number with higher ADC value than the control group (P < 0.05). On K-WAB evaluation, aphasia quotient and language quotient were 95.9 ± 4.1 (range 85-100) and 95.0 ± 5.4 (range 80-100), respectively. However, 23 (92.0%) of 25 patients complained of language-related symptoms after TBI; paraphasia in 12 (48.0%) patients, deficits of comprehension in 4 (16.0%) patients, deficits of speech production in 1 (4.0%) patient, and >2 language symptoms in 6 (24.0%) patients. We found that a significant number (39%) of patients with mild TBI had injury of the AF in the dominant hemisphere and these patients had mild language deficit. These results suggest that DTT could provide useful information in detecting injury of the AF and evaluation of the AF using DTT would be necessary even in the case of a patient with mild TBI who complains of mild language deficit.

    BACKGROUND & AIMS Patients with acute liver failure (ALF) frequently develop renal dysfunction, yet its overall incidence and outcomes have not been fully assessed. We investigated the incidence of acute kidney injury (AKI) among patients with ALF, using defined criteria to identify risk factors and to evaluate its effect on overall outcomes. METHODS We performed a retrospective review of data from 1604 patients enrolled in the Acute Liver Failure Study Group, from 1998 through 2010. Patients were classified by the Acute Kidney Injury Network criteria, as well as for etiology of liver failure (acetaminophen-based, ischemic, and all others). RESULTS Seventy percent of patients with ALF developed AKI, and 30% received renal replacement therapy (RRT). Patients with severe AKI had higher international normalized ratio values than those without renal dysfunction (P < .001), and a higher proportion had advanced-grade coma (coma grades 3 or 4; P < .001) or presented with hypotension requiring vasopressor therapy (P < .001). A greater proportion of patients with acetaminophen-induced ALF had severe kidney injury than of patients with other etiologies of ALF; 34% required RRT, compared with 25% of patients with ALF not associated with acetaminophen or ischemia (P < .002). Of the patients with ALF who were alive at 3 weeks after study entry, significantly fewer with AKI survived for 1 year. Although AKI reduced the overall survival time, more than 50% of patients with acetaminophen-associated or ischemic ALF survived without liver transplantation (even with RRT), compared with 19% of patients with ALF attribute to other causes (P < .001). Only 4% of patients requiring RRT became dependent on dialysis. CONCLUSIONS Based on a retrospective analysis of data from more than 1600 patients, AKI is common in patients with ALF and affects short- and long-term outcomes, but rarely results in chronic kidney disease. Acetaminophen-induced kidney injury is frequent, but patients have

    Objective: To evaluate the usefulness of conventional spinal surgery as palliative procedure to rehabilitate dorsolumbar injuries in a rural setup. Materials and Methods: Twenty-three patients with dorsolumbar spine injury with complete paraplegia were assessed on the clinical and social rehabilitation parameters after surgical stabilization at Acharya Vinoba Bhave Rural Hospital Sawangi, Wardha, India. The study group comprised 21 male and 2 female patients. The dorsolumbar spine injury was fixed by conventional posterior instrumentation using short-segment pedicle screw system and Harrington rod system with or without fusion. Functional and neurologic outcome was recorded in the follow-up period by using Functional Independence Measure and Frankel grade, respectively. Correlation and analysis of results was established statistically. Results: Functional outcome showed statistically significant improvement. Social cognition was found intact in a significant number of patients. Conclusion: This study demonstrates the usefulness of conventional instrumentation as palliative surgical approach to stabilize and rehabilitate patients from deprived sector of rural India.

    2015-01-01

    New Zealand’s treatment injury compensation claims data set provides an uncommon no-fault perspective of patient safety incidents. Analysis of primary care claims data confirmed medication as the leading threat to the safety of older patients in primary care and drew particular attention to the threat posed by antibiotics. For most injuries there was no suggestion of error. The no-fault perspective reveals the greatest threat to the safety of older patients in primary care to be, not error, but the risk posed by treatment itself. To improve patients’ safety, in addition to reducing error, clinicians need to reduce patients’ exposure to treatment risk, where appropriate. PMID:26371269

    Context: Trauma in South Asia is an increasingly significant problem, particularly in light of increasing motorization. Societal changes are resulting in alterations in the epidemiology of trauma. Aims: To assess various epidemiological parameters that influence causation of injury in the patients admitted in a major trauma center in Northern India. Settings and Design: Prospective, cross-sectional, Hospital based study from August 2008 to July 2009. Materials and Methods: A prospective study of 748 patients chosen by random assortment was carried out over a period of 1 year (August 2008 to July 2009) and following parameters were noted: Age group, sex, mode of trauma, type of injury, place where the trauma occurred and factors leading to injury. The length of stay of patients, Kampala trauma score (KTS) and mortality depending on the arrival time in emergency department was also noted. Statistical Analysis: Data analysis was performed using SPSS Version 16. Results: Overall trauma was most common in the age group 15-30 years (Mean age: 29.43 ± 16.87 years), with male constituting 85.29% of the total patients. It was observed that road side injuries were the most frequent (66.71%) site of injuries, whereas household injuries (23.66%), farm site (6.28%), work place (1.60) were the next most common modes of trauma. Mean time of presentation of injured patient was 2.53 ± 4.92 days. About 48.13% patients were admitted after more than 24 h after the injury. Two wheelers (32.09) were found to be the most common mode of injury. Maximum injuries (65.31%) occurred in the rural setting. The overall length of hospital stay ranged from 2 days to 178 days (median15.6 days). Mortality is more in patients who arrive in night (between 9 pm and 5 pm). Conclusions: We conclude that the majority of injuries are preventable and the epidemiological trends differ from that of developed countries. Therefore, preventive strategies should be made on the basis of these epidemiological

    We report about 48 patients who sustained a deceleration trauma after jumping out of a window. The average free fall height was 11.6 m. 45.8% of the patients suffered from psychic disorders. 12.5% were addicted to opiates or hallucinogenics. The lethality of the analysed group was 12.5%. Within the group of spinal injuries (66.7%) compression- and bursting vertebra fractures of the thoracolumbar spine dominate. Injuries of the osseus pelvic ring (62.5%) and the thorax (64.6%) were equally often in all free falls. Abdominal- (25%) and head trauma (35.4%) occurred less at the patients in our clinic. At the extremities a predeliction of injuries of joint near and joint building osseus structures was noticeable. Out of the 103 injuries of the lower extremities 57.3% concerned foot, ankle and the distal lower leg. With increasing height of the falls the rate of multi-injuries and chain fractures raised. Out of the 37 injuries of the upper extremities 40.5% concerned hand and distal forearm and 29.7% the elbow. PMID:9381605

  10. Texas passes first law for safe patient handling in America: landmark legislation protects health-care workers and patients from injury related to manual patient lifting.

    2005-01-01

    On June 17,2005, Texas Governor Rick Perry (R) signed into law Senate Bill 1525, making Texas the first state in the nation to require hospitals and nursing homes to implement safe patient handling and movement programs. Governor Perry is to be commended for this heroic first stand for safe patient handling in America. The landmark legislation will take effect January 1, 2006, requiring the establishment of policy to identify, assess, and develop methods of controlling the risk of injury to patients and nurses associated with lifting, transferring, repositioning, and movement of patients; evaluation of alternative methods from manual lifting to reduce the risk of injury from patient lifting, including equipment and patient care environment; restricting, to the extent feasible with existing equipment, manual handling of all or most of a patient's weight to emergency, life-threatening, or exceptional circumstances; and provision for refusal to perform patient handling tasks believed to involve unacceptable risks of injury to a patient or nurse. Manually lifting patients has been called deplorable, inefficient, dangerous to nurses, and painful and brutal to patients; manual lifting can cause needless suffering and injury to patients, with dangers including pain, bruising, skin tears, abrasions, tube dislodgement, dislocations, fractures, and being dropped by nursing staff during attempts to manually lift. Use of safe, secure, mechanical lift equipment and gentle friction-reducing devices for patient maneuvering tasks could eliminate such needless brutality. Research has proven that manual patient lifting is extremely hazardous to health-care workers, creating substantial risk of low-back injury, whether with one or two patient handlers. Studies on the use of mechanical patient lift equipment, by either nursing staff or lift teams, have proven repeatedly that most nursing staff back injury is preventable, leading to substantial savings to employers on medical and

    Objective To examine the factors associated with acute kidney injury and outcome in patients with lung disease. Methods A prospective study was conducted with 100 consecutive patients admitted to a respiratory intensive care unit in Fortaleza (CE), Brazil. The risk factors for acute kidney injury and mortality were investigated in a group of patients with lung diseases. Results The mean age of the study population was 57 years, and 50% were male. The incidence of acute kidney injury was higher in patients with PaO2/FiO2<200 mmHg (54% versus 23.7%; p=0.02). Death was observed in 40 cases and the rate of mortality of the acute kidney injury group was higher (62.8% versus 27.6%; p=0.01). The independent factor that was found to be associated with acute kidney injury was PaO2/FiO2<200 mmHg (p=0.01), and the independent risk factors for death were PEEP at admission (OR: 3.6; 95%CI: 1.3-9.6; p=0.009) and need for hemodialysis (OR: 7.9; 95%CI: 2.2-28.3; p=0.001). Conclusion There was a higher mortality rate in the acute kidney injury group. Increased mortality was associated with mechanical ventilation, high PEEP, urea and need for dialysis. Further studies must be performed to better establish the relationship between kidney and lung injury and its impact on patient outcome. PMID:23917978

    To identify and characterize otherwise occult inter-individual spatial variation of white matter abnormalities across mild traumatic brain injury (mTBI) patients. After informed consent and in compliance with Health Insurance Portability and Accountability Act (HIPAA), Diffusion tensor imaging (DTI) was performed on a 3.0 T MR scanner in 34 mTBI patients (19 women; 19-64 years old) and 30 healthy control subjects. The patients were imaged within 2 weeks of injury, 3 months after injury, and 6 months after injury. Fractional anisotropy (FA) images were analyzed in each patient. To examine white matter diffusion abnormalities across the entire brain of individual patients, we applied Enhanced Z-score Microstructural Assessment for Pathology (EZ-MAP), a voxelwise analysis optimized for the assessment of individual subjects. Our analysis revealed areas of abnormally low or high FA (voxel-wise P-value < 0.05, cluster-wise P-value < 0.01(corrected for multiple comparisons)). The spatial pattern of white matter FA abnormalities varied among patients. Areas of low FA were consistent with known patterns of traumatic axonal injury. Areas of high FA were most frequently detected in the deep and subcortical white matter of the frontal, parietal, and temporal lobes, and in the anterior portions of the corpus callosum. The number of both abnormally low and high FA voxels changed during follow up. Individual subject assessments reveal unique spatial patterns of white matter abnormalities in each patient, attributable to inter-individual differences in anatomy, vulnerability to injury and mechanism of injury. Implications of high FA remain unclear, but may evidence a compensatory mechanism or plasticity in response to injury, rather than a direct manifestation of brain injury. PMID:22684769

    Thirty-two multiple trauma patients with severe head injury and a Glasgow Coma Scale (GCS) score of 8 or less were prospectively studied to assess the occurrence of deep venous thrombosis (DVT) and pulmonary embolism (PE). All patients required mechanical ventilation. A sequential compression device (SCD) was used in 14 patients and 18 patients received no prophylaxis for thromboembolism. Bilateral lower extremity technetium venoscans and ventilation/perfusion (V/Q) lung scans were performed within 6 days of admission and every week for 1 month or until the patient developed DVT or PE or was discharged from the SICU. Deep venous thrombosis occurred in two patients (6%) at 16 and 28 days following trauma. Twenty-five patients had normal or low probability V/Q scans. Six had high probability V/Q scans confirmed by pulmonary arteriograms (PAGs) at 12.5 +/- 4 days. Clinical signs of PE were absent in all patients with a positive PAG. There were no differences in age, Injury Severity Score (ISS), GCS Score, APACHE II Score, or Trauma Score between the patients who developed DVT or PE and those who did not. A SCD was used in four of the eight patients with DVT or PE. All but one patient with DVT or PE underwent placement of a vena caval filter. Multiple trauma patients with severe head injury (GCS score < or = 8) are at high risk for thromboembolism. The available means of prevention and diagnosis of DVT or PE in multiple trauma patients with severe head injury are not entirely effective. PMID:8064917

    Abnormalities of cognitive function and high levels of depression incidence are characteristic of hemodialysis patients. Although previously attributed to the humoral effects of uremia, it is becoming increasingly appreciated that many elements of the overall disease state in CKD patients contribute to functional disturbances and physical brain injury. These factors range from those associated with the underlying primary diseases (cardiovascular, diabetes etc.) to those specifically associated with the requirement for dialysis (including consequences of the hemodialysis process itself). They are, however, predominantly ischemic threats to the integrity of brain tissue. These evolving insights are starting to allow nephrologists to appreciate the potential biological basis of dependency and depression in our patients, as well as develop and test new therapeutic approaches to this increasingly prevalent and important issue. This review aims to summarize the current understanding of brain injury in this setting, as well as examine recent advances being made in the modification of dialysis-associated brain injury.

    Nutraceuticals are supplements and medical foods that offer numerous health benefits. However, these substances may have adverse effects on multiple organ systems, leading to significant morbidity. I present a patient with chronic kidney disease who experienced hemodynamically mediated acute kidney injury and hyperkalemia after daily consumption of cherry concentrate. The method of injury was most likely cyclooxygenase inhibition by the compounds in cherries that mimic the mechanism of action of nonsteroidal anti-inflammatory medications. Ceasing cherry concentrate consumption led to improvements in both the patient's hyperkalemia and kidney injury. Physicians should be aware of the potentially harmful side effects of cherry concentrate and approach the use of cherry extract or concentrate with caution in patients with underlying kidney disease.

    Older adults frequently present to the emergency department (ED) with injuries that do not require operative treatment but are sufficiently severe to make it unsafe for them to return home. These patients typically do not meet criteria for an ‘inpatient’ hospital admission. However, because of the limited reimbursement for observation patients, admitting physicians are often reluctant to accept these patients in to observation. Admission to a skilled nursing or assisted living facility from the ED or rapid access to additional in-home care is also often difficult or impossible. As a result, older patients with non-operative injuries often spend a long time in the ED waiting for an appropriate disposition. We describe the challenges of identifying an appropriate disposition for these patients, the consequences for patients, and some potential solutions to this commonly encountered problem.

    The objective of this study was to evaluate the genotype and allelic frequencies of CYP1A2 in Chinese patients with acute liver injury induced by Polygonum multiflorum. We examined the clinical mechanism of acute liver injury induced by P. multiflorum. According to the diagnostic criteria for drug-induced liver injury (DILI), 43 cases of P. multiflorum-induced liver injury admitted to the First Affiliated Hospital, Zhejiang University were identified between January 2008 and December 2012. An additional 43 control subjects were also chosen. Several alleles, including 1C, 1F, 2, 7, 9, and 11 of CYP1A2 were amplified from genomic DNA and sequenced. We used the chi-square test to determine whether CYP1A2 allele polymorphisms are associated with acute liver injury induced by P. multiflorum. The frequency of the CYP1A2 1C allele was 46.5% in P. multiflorum-induced DILI patients, which was significantly different from the frequency of 27.9% observed in healthy subjects. The frequency of the CYP1A2 1F allele was 63.9% in P. multiflorum-induced DILI patients, compared to 57.0% in healthy controls; the difference was not significant. The allelic frequencies of CYP1A2 2, CYP1A2 7, CYP1A2 9, and CYP1A2 11 were too low to be detected. The frequency of the CYP1A2 1C mutation in Chinese patients with P. multiflorum-induced acute liver injury differed from that in healthy Chinese people, indicating that CYP1A2 1C is probably related to metabolism of P. multiflorum, which is followed by acute liver injury.

    Objective Patients with traumatic brain injury are particularly susceptible to sepsis, which may exacerbate the systemic inflammatory response and lead to organ dysfunction. The influence of clinical variables on the mortality of intensive care unit patients with traumatic brain injury and sepsis was investigated. Methods The present investigation was a retrospective study involving 175 patients with traumatic brain injury who were treated in a period of 1 year at a reference hospital for trauma and who had sepsis, severe sepsis, or septic shock. Demographic and clinical data were obtained, and the SOFA score was calculated at the time sepsis was found and after 72 hours. Results There was a predominance of young men with severe traumatic brain injury, multiple head injuries, sepsis with a pulmonary focus, prolonged hospital stay, and high mortality (37.7%). Circulatory and respiratory failure had a high incidence, but renal and coagulation failure were less frequent, and liver failure was not observed. After logistic regression, the presence of septic shock and respiratory failure 72 hours after the sepsis diagnosis was associated with higher mortality, with an odds ratio of 7.56 (95%CI=2.04-27.31, p=0.0024) and 6.62 (95%CI=1.93-22.78, p=0.0027), respectively. In addition, there was a higher mortality among patients who had no organ failure on D1 but who developed the condition after 72 hours of sepsis and in those patients who already had organ failure at the time sepsis was diagnosed and remained in this condition after 72 hours. Conclusion Septic shock and progressive organ (particularly respiratory) dysfunction increases the mortality of patients with traumatic brain injury and sepsis. PMID:25028949

    Purpose: The purpose of this study was to determine the effects of atlas selection based on different morphometric parameters, on the accuracy of automatic brachial plexus (BP) segmentation for radiation therapy planning. The segmentation accuracy was measured by comparing all of the generated automatic segmentations with anatomically validated gold standard atlases developed using cadavers. Methods and Materials: Twelve cadaver computed tomography (CT) atlases (3 males, 9 females; mean age: 73 years) were included in the study. One atlas was selected to serve as a patient, and the other 11 atlases were registered separately onto this “patient” using deformable image registration. This procedure was repeated for every atlas as a patient. Next, the Dice and Jaccard similarity indices and inclusion index were calculated for every registered BP with the original gold standard BP. In parallel, differences in several morphometric parameters that may influence the BP segmentation accuracy were measured for the different atlases. Specific brachial plexus-related CT-visible bony points were used to define the morphometric parameters. Subsequently, correlations between the similarity indices and morphometric parameters were calculated. Results: A clear negative correlation between difference in protraction-retraction distance and the similarity indices was observed (mean Pearson correlation coefficient = −0.546). All of the other investigated Pearson correlation coefficients were weak. Conclusions: Differences in the shoulder protraction-retraction position between the atlas and the patient during planning CT influence the BP autosegmentation accuracy. A greater difference in the protraction-retraction distance between the atlas and the patient reduces the accuracy of the BP automatic segmentation result.

    Various intraventricular tumors can present with calcifications; however, the choroid plexus can also have physiological calcifications. This is the first case report of meningiomas located at the bilateral foramen of Monro (FOM), concealed by a grossly calcified choroid plexus, presenting with obstructive hydrocephalus. A 60-year-old woman with disturbed consciousness was admitted by ambulance. Head computed tomography revealed significantly high-density lesions that smoothly extended from the choroid plexus of the lateral ventricles to the third ventricle. They occupied both sides of the FOM, resulting in obstructive hydrocephalus. The diagnostic endoscopic biopsy was performed using a flexible neuroendoscopic system, and an egg shell-like grossly calcified choroid plexus was found to smoothly extend toward the FOM. Resection was not selected because the calcified lesions had tightly adhered to the veins and fornix; therefore, the patient underwent ventriculo-peritoneal shunting. The lesions were histologically identified as psammomatous meningiomas with low proliferation potential (the Ki-67 labeling index was lower than 1%). She was discharged 10 days after surgery without neurological deficits. As calcifications can have tumoral and nontumoral origins, we considered neuroendoscopic exploration to be essential in order to achieve an accurate diagnosis and select optimal management.

    Objectives: The timing of definitive fixation for major fractures in patients with multiple injuries is controversial. To address this gap, we randomized patients with blunt multiple injuries to either initial definitive stabilization of the femur shaft with an intramedullary nail or an external fixateur with later conversion to an intermedullary nail and documented the postoperative clinical condition. Methods: Multiply injured patients with femoral shaft fractures were randomized to either initial (<24 hours) intramedullary femoral nailing or external fixation and later conversion to an intramedullary nail. Inclusion: New Injury Severity Score >16 points, or 3 fractures and Abbreviated Injury Scale score ≥2 points and another injury (Abbreviated Injury Scale score ≥2 points), and age 18 to 65 years. Exclusion: patients in unstable or critical condition. Patients were graded as stable or borderline (increased risk of systemic complications). Outcomes: Incidence of acute lung injuries. Results: Ten European Centers, 165 patients, mean age 32.7 ± 11.7 years. Group intramedullary nailing, n = 94; group external fixation, n = 71. Preoperatively, 121 patients were stable and 44 patients were in borderline condition. After adjusting for differences in initial injury severity between the 2 treatment groups, the odds of developing acute lung injury were 6.69 times greater in borderline patients who underwent intramedullary nailing in comparison with those who underwent external fixation, P < 0.05. Conclusion: Intramedullary stabilization of the femur fracture can affect the outcome in patients with multiple injuries. In stable patients, primary femoral nailing is associated with shorter ventilation time. In borderline patients, it is associated with a higher incidence of lung dysfunctions when compared with those who underwent external fixation and later conversion to intermedullary nail. Therefore, the preoperative condition should be when deciding on the type of

    Background Most deaths in patients with abdominal vascular injuries (ABVI) are caused by exsanguination and irreversible shock. Therefore, time to definitive hemorrhage control is an important factor affecting survival. The study goals were: (1) document current outcomes in patients with ABVI, and (2) compare outcomes to those from the era preceding improvements in an urban prehospital system. Methods A retrospective review of all patients with ABVI at an urban level 1 trauma center was completed. Patients injured prior to prehospital transport improvements (1991–1994) were compared to those following a reduction in transport times (1995–2004). Results Of 388 patients, 70 (18%) arrived prior to prehospital improvements (1991–1994). Patient/injury demographics were similar in both groups (age, sex, penetrating mechanism; p > 0.05). The number of patients presenting with ABVI increased (23 vs. 35 per year; p < 0.05) concurrent to a reduction in transport times (27 vs. 20 minutes; p < 0.05). Patients were more frequently unstable (63% vs. 91%; p < 0.05). Regardless of the specific vessel, mortality increased (37% vs. 67%; p < 0.05) following prehospital improvements. Conclusions A reduction in urban transport times resulted in an increase in (1) the number of patients arriving with abdominal vascular injuries, (2) the proportion presenting in physiologic extremis, and (3) overall mortality.

    Aim We aimed to identify the characteristics and prognostic indicators of poor visual and anatomic outcome in pseudophakic patients with fall-related open-globe (OG) injuries. We used a case series design, for a total of 26 patients. Methods Charts of consecutive pseudophakic patients with fall-related OG injury at a single institution were reviewed. Demographics, ophthalmic history, circumstances of injury, initial best-corrected visual acuity (BCVA), examination findings, surgical interventions, and follow-up BCVA were tabulated for statistical analysis with unpaired t-tests and Fisher’s exact tests. Results Nineteen patients (73%) were women. Mean (± standard deviation) age was 80.6±4.6 years (range: 61–97 years). Initial BCVA was <20/400 in 24 of 25 patients (96%). Mean ocular trauma score (OTS) was 38.54±10.95. OTS was lower (P=0.0017, P<0.0001, and P=0.0240) and wound size was larger (P=0.0440, 0.0145, and 0.0026) in patients with final BCVA <20/40, <20/400, and phthisis at final follow-up, respectively; compared to patients with BCVA ≥20/40, 20/400, and no phthisis at final follow-up, respectively. Final BCVA <20/400 was associated with 360° subconjunctival hemorrhage (SCH), retinal detachment, and proliferative vitreoretinopathy (P=0.0498, 0.0181, and 0.0310, respectively). Total hyphema, intraocular lens (IOL) damage, and IOL expulsion were associated with needing multiple surgical interventions (P=0.0345, P<0.0001, and P=0.0023, respectively). Conclusion Large wound size, low OTS, 360° SCH, total hyphema, posterior injury, and IOL damage are common findings that are also prognostic of poor visual and anatomic outcome in pseudophakic patients with fall-related OG injuries. Ophthalmologists dealing primarily with geriatric populations should contribute to the discussion of fall risk. PMID:25784783

    Introduction The National Emergency X-radiography Utilization Study (NEXUS) criteria are used extensively in emergency departments to rule out C-spine injuries (CSI) in the general population. Although the NEXUS validation set included 2,943 elderly patients, multiple case reports and the Canadian C-Spine Rules question the validity of applying NEXUS to geriatric populations. The objective of this study was to validate a modified NEXUS criteria in a low-risk elderly fall population with two changes: a modified definition for distracting injury and the definition of normal mentation. Methods This is a prospective, observational cohort study of geriatric fall patients who presented to a Level I trauma center and were not triaged to the trauma bay. Providers enrolled non-intoxicated patients at baseline mental status with no lateralizing neurologic deficits. They recorded midline neck tenderness, signs of trauma, and presence of other distracting injury. Results We enrolled 800 patients. One patient fall event was excluded due to duplicate enrollment, and four were lost to follow up, leaving 795 for analysis. Average age was 83.6 (range 65–101). The numbers in parenthesis after the negative predictive value represent confidence interval. There were 11 (1.4%) cervical spine injuries. One hundred seventeen patients had midline tenderness and seven of these had CSI; 366 patients had signs of trauma to the face/neck, and 10 of these patients had CSI. Using signs of trauma to the head/neck as the only distracting injury and baseline mental status as normal alertness, the modified NEXUS criteria was 100% sensitive (CI [67.9–100]) with a negative predictive value of 100 (98.7–100). Conclusion Our study suggests that a modified NEXUS criteria can be safely applied to low-risk elderly falls. PMID:27330655

    Mitochondrial injury contributes to renal dysfunction in several models of renal disease, but its involvement in human hypertension remains unknown. Fragments of the mitochondrial genome released from dying cells are considered surrogate markers of mitochondrial injury. We hypothesized that hypertension would be associated with increased urine mitochondrial DNA (mtDNA) copy numbers. We prospectively measured systemic and urinary copy number of the mtDNA genes cytochrome-c oxidase-3 and NADH dehydrogenase subunit-1 by quantitative polymerase chain reaction in essential (n=25) and renovascular (RVH, n=34) hypertensive patients and compared them with healthy volunteers (n=22). Urinary kidney injury molecule-1 and neutrophil gelatinase-associated lipocalin served as indices of renal injury. Renal blood flow and oxygenation were assessed by multidetector computed tomography and blood oxygen level-dependent magnetic resonance imaging. Blood pressure, urinary neutrophil gelatinase-associated lipocalin, and kidney injury molecule-1 were similarly elevated in essential hypertension and RVH, and estimated glomerular filtration rate was lower in RVH versus healthy volunteers and essential hypertension. Renal blood flow was lower in RVH compared with essential hypertension. Urinary mtDNA copy number was higher in hypertension compared with healthy volunteers, directly correlated with urinary neutrophil gelatinase-associated lipocalin and kidney injury molecule-1 and inversely with estimated glomerular filtration rate. In RVH, urinary mtDNA copy number correlated directly with intrarenal hypoxia. Furthermore, in an additional validation cohort, urinary mtDNA copy number was higher in RVH compared with healthy volunteers (n=10 each). The change in serum creatinine levels and estimated glomerular filtration rate 3 months after medical therapy without or with revascularization correlated with the change in urinary mtDNA. Therefore, elevated urinary mtDNA copy numbers in

    [Purpose] The primary aim of this study was to assess rehabilitation outcomes for early and two-stage repair of hand flexor tendon injuries. The secondary purpose of this study was to compare the findings between treatment groups. [Subjects and Methods] Twenty-three patients were included in this study. Early repair (n=14) and two-stage repair (n=9) groups were included in a rehabilitation program that used hand splints. This retrospective evaluated patients according to their demographic characteristics, including age, gender, injured hand, dominant hand, cause of injury, zone of injury, number of affected fingers, and accompanying injuries. Pain, range of motion, and grip strength were evaluated using a visual analog scale, goniometer, and dynamometer, respectively. [Results] Both groups showed significant improvements in pain and finger flexion after treatment compared with baseline measurements. However, no significant differences were observed between the two treatment groups. Similar results were obtained for grip strength and pinch grip, whereas gross grip was better in the early tendon repair group. [Conclusion] Early and two-stage reconstruction of patients with flexor tendon injuries can be performed with similarly favorable responses and effective rehabilitation programs.

    During visits to emergency medical facilities, the primary care of and risk identification for individuals who have attempted suicide is considered an important element in suicide prevention. With the ultimate goal of helping to prevent suicide, the aim of the present study was to determine the characteristics of patients with self-inflicted injuries who presented in the emergency department. Patients with self-inflicted injuries who visited 1 of 3 sentinel emergency medical centers from 2007 through 2009 were included in the study. The characteristics, methods, and reasons for suicide attempts were evaluated. Moreover, predictors of severe outcomes were evaluated. A total of 2,996 patients with self-inflicted injuries visited the three centers during a period of 3 yr. The male-to-female suicide ratio was 1:1.38 (P < 0.001). The mean age was 41 yr. Poisoning was the most common method of self-inflicted injury (68.7%) among all age groups. Medication was the primary means of injury in the < 50 age group, and the use of agricultural chemicals was the primary means in the ≥ 50 age group. The reasons for attempting suicide varied among the age groups. The predictors of severe outcome are male gender, older age, and not having consumed alcohol. PMID:22379343

    Persistent detrusor acontractility despite normal somatic reflex activity in some patients with high spinal cord injury is an enigma. Previous work has suggested disordered integration of afferent activity in sacral roots or the sacral spinal cord. Forty male patients with chronic stable suprasacral cord lesions were studied by filling and voiding videocystometrography, and recording lumbosacral evoked potentials from posterior tibial nerve stimulation. Only five of 15 patients with decreased detrusor contractility had abnormal lumbosacral evoked potentials. Similar abnormalities were found in four of 11 patients with efficient hyperreflexic bladders. The finding of normal lumbosacral evoked potentials in the majority of patients with suprasacral cord injuries and decreased detrusor contractility supports the argument that the pathophysiology of this specific form of neurogenic bladder dysfunction is multifactorial.

    We report helicopter transportation of a sedated, mechanically ventilated patient with cervical cord injury. A 20-year-old male sustained traumatic injury to the cervical spinal cord during extracurricular activities in a college. On arrival at the hospital, a halo vest was placed on the patient and tracheostomy was performed. On the 38th hospital day, he was transported a distance of 520km by helicopter to a specialized hospital in Fukuoka for medical repatriation. Cabin space was narrow. Since power supply and carrying capacity were limited, battery-driven and portable medical devices were used. In consideration for patient's psychological stress, he was sedated with propofol. RSS (Ramsay sedation scale) scores were recorded to evaluate whether the patient was adequately sedated during helicopter transportation. Prior to transport, we rehearsed the sedation using bispectral index monitoring (BIS) in the hospital to further ensure the patient's safety during the transport. PMID:24063142

    Background: We previously showed that thermal injury depletes plasma vitamin E in pediatric burn patients; however, plasma changes may reflect immediate alterations in vitamin E nutriture. Adipose tissue α-tocopherol concentrations are generally accepted to reflect long-term vitamin E status. Objective: To test the hypothesis that thermal injury depletes body stores of vitamin E, α-tocopherol concentrations were measured in adipose tissue samples. Design: Pediatric patients (n = 8) were followed up to 1 y after burn injury. Surgically obtained samples were collected at various intervals and stored at −80°C in a biorepository. α- and γ-Tocopherols, cholesterol, and triglycerides were measured in the same tissue aliquot. Results: During the first week after injury, adipose tissue α-tocopherol concentrations were within the expected normal range of 199 ± 40 nmol/g adipose tissue but were substantially lower at weeks 2 and 3 (133 ± 13 and 109 ± 8 nmol/g adipose tissue, respectively). Individual rates of decrease, estimated by linear regression, showed that adipose tissue α-tocopherol decreased by an average of 6.1 ± 0.6 nmol/g daily. During the first month after injury, adipose tissue triglyceride concentrations also decreased, whereas no changes in cholesterol concentrations occurred. Conclusions: These data emphasize that the burn injury experienced by these pediatric patients altered their metabolism such that vitamin E status diminished during the month after injury. Further studies are needed to evaluate the mechanism and consequences of the observed vitamin E depletion. This trial was registered at clinicaltrials.gov as NCT00675714. PMID:20881067

    Background The present study compared sociodemographic characteristics, comorbidities with substance use, and impulsivity features in three groups of psychiatric patients – suicide attempters, nonsuicidal self-injury, and nonsuicidal without self-injury – to determine the predictive factors for nonsuicidal self-injury or suicide behavior. Patients and methods Demographic features and self-reported substance use were assessed in 384 Mexican psychiatric patients. Impulsivity features were evaluated using the Plutchik Impulsivity Scale. Comparison analyses between groups were performed and a logistic regression model used to determine the factors associated with nonsuicidal with self-injury behavior and suicidal behavior. Results Different predictive factors were observed for nonsuicidal self-injury and suicidal behavior. Females were more likely to present nonsuicidal self-injury behaviors (odds ratio [OR] 0.42, 95% confidence interval [CI] 0.18–0.93; P=0.03). For suicide attempters, the factors associated were younger age (OR 0.89, 95% CI 0.85–0.93; P<0.001), less than 6 years of schooling (OR 0.2, 95% CI 0.06–0.6; P=0.004), and higher impulsivity traits, such as self-control (OR 1.19, 95% CI 1.03–1.36; P=0.01), planning of future actions (OR 0.79, 95% CI 0.66–0.95; P=0.01), and physiological behavior (OR 1.34, 95% CI 1.01–1.78; P=0.03). Conclusion Our results show that in a Mexican population, impulsivity features are predictors for suicide attempts, but not for self-injury. Other factors related to sociocultural background and individual features (such as personality) may be involved in this behavioral distinction, and should be studied in future research aimed at better understanding of both self-harmful behaviors.

    Rehabilitation can improve cognitive deficits observed in patients with traumatic brain injury (TBI). However, despite rehabilitation, the ability of making a choice often remains impaired. Risk taking is a daily activity involving numerous cognitive processes subserved by a complex neural network. In this work we investigated risk taking using the Balloon Analogue Risk Task (BART) in patients with acute TBI and healthy controls. We hypothesized that individuals with TBI will take less risk at the BART as compared to healthy individuals. We also predicted that within the TBI group factors such as the number of days since the injury, severity of the injury, and sites of the lesion will play a role in risk taking as assessed with the BART. Main findings revealed that participants with TBI displayed abnormally cautious risk taking at the BART as compared to healthy subjects. Moreover, healthy individuals showed increased risk taking throughout the task which is in line with previous work. However, individuals with TBI did not show this increased risk taking during the task. We also investigated the influence of three patients' characteristics on their performance at the BART: Number of days post injury, Severity of the head injury, and Status of the frontal lobe. Results indicate that performance at the BART was influenced by the number of days post injury and the status of the frontal lobe, but not by the severity of the head injury. Reported findings are encouraging for risk taking seems to naturally improve with time postinjury. They support the need of conducting longitudinal prospective studies to ultimately identify impaired and intact cognitive skills that should be trained postinjury. PMID:24386232

    [Purpose] This prospective longitudinal study evaluated the changes in bone metabolism markers and bone mineral density of spinal cord injury patients over 3 years. We also assessed the relationships among the bone mineral density, bone metabolism, and clinical data of spinal cord injury patients. [Subjects and Methods] We assessed the clinical data (i.e., immobilization due to surgery, neurological status, neurological level, and extent of lesion) in 20 spinal cord injury patients. Bone mineral density, and hormonal and biochemical markers of the patients were measured at 0, 6, 12, and 36 months. [Results] Femoral neck T score decreased significantly at 36 months (p < 0.05). Among the hormonal markers, parathyroid hormone and vitamin D were significantly elevated, while bone turnover markers (i.e., deoxypyridinoline and osteocalcin) were significantly decreased at 12 and 36 months (p < 0.05). [Conclusion] Bone mineral density of the femoral neck decreases significantly during the long-term follow-up of patients with spinal cord injury due to osteoporosis. This could be due to changes in hormonal and bone turnover markers. PMID:26157234

Serum acute phase reactant proteins (APRP), complement activation and immunoglobulines as immunological parameters were studied. APRP are produced in the liver and increase in cancer patients as well as those with acute and chronic inflammations, trauma and autoimmune diseases. APRP are known to be one of the immunosuppressive factors in the serum. Forty patients with acute head injuries were studied. Thirty-four patients were male and six patients were female, ages ranged from 12 to 81 years. Serial blood samples were obtained during the first seven days of trauma. The Glasgow Coma Score (GCS) were recorded at the time of admission for all patients. Clinical outcome was assessed at the time of discharge according to the Glasgow Outcome Scale. The "good" group consisted of patients with good recovery or moderate disability. The "bad" group consisted of patients with severe disability, persistent vegetative state and death. The concentrations of immunoglobulines (IgG, IgM, IgA) were within normal range and humoral immunity was not affected. Complement activation at the time of admission was closely related to GCS (p less than 0.01), but the levels of C4, C3, and C3 activator except for these of CH50 were within normal range.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2451531

    Health care organizations must adopt a culture of safety and implement effective fall prevention protocols. The teach-back method is a useful strategy for health providers to determine patient understanding of information taught to maintain a safe environment and prevent falls. Purposeful rounding is a proactive approach to ensure that patient assessments are accurate and research supports that patients use the call light less when nurses participate in hourly rounding. This article provides the reader with evidence-based fall prevention interventions, tips for using the teach-back method, and fall prevention tools to safely care for patients of all ages.

    This letter to the editor describes the case of a 42 year old man with mild traumatic brain injury and multiple neuropsychiatric symptoms which persisted for a few years after the injury. Initial CT scans and MRI scans of the brain showed no signs of atrophy. Brain volume was measured using NeuroQuant®, an FDA-approved, commercially available software method. Volumetric cross-sectional (one point in time) analysis also showed no atrophy. However, volumetric longitudinal (two points in time) analysis showed progressive atrophy in several brain regions. This case illustrated in a single patient the principle discovered in multiple previous group studies, namely that the longitudinal design is more powerful than the cross-sectional design for finding atrophy in patients with traumatic brain injury.

    A 17-year-old male with diffuse axonal injury (DAI) was referred to our psychiatric clinic with a diagnosis of depression. However, further investigation indicated that he had narcolepsy without cataplexy secondary to DAI. We assessed regional volume alterations in the patient; MRI analysis showed a significant decrease in the volume of the hypothalamus, left amygdala, and brainstem. Our findings add to further understanding of the structural basis of secondary narcolepsy, and may provide basis for future neuroimaging studies on sleep disturbances in traumatic brain injury (TBI).

    OBJECTIVE: To test the hypothesis that treatment with bromocriptine would ameliorate deficits in clinical motivation, responsiveness to reward, and frontal cognitive function after brain injury. METHOD: An open trial in six men and five women who had had either traumatic brain injury or subarachnoid haemorrhage between two months and five years previously. After repeated baseline assessments, bromocriptine was given in gradually increasing doses. Assessments were repeated at increasing doses, during maintenance, and after withdrawal. Novel structured instruments for quantifying motivation were developed; measures of anxiety and depression, and cognitive tests sensitive to motivation or frontal lobe involvement were also given. RESULTS: Bromocriptine treatment was followed by improved scores on all measures other than mood. Improvement was maintained after bromocriptine withdrawal in eight of the patients. CONCLUSION: Poor motivation in patients with brain injury may result from dysfunction in the mesolimbic/mesocortical dopaminergic circuitry, giving rise to associated deficiencies in reward responsiveness and frontal cognitive function.

    [Purpose] The purpose of this study was to compare the effects of body weight-supported treadmill training (BWSTT) and robot-assisted rehabilitation (RAT) on bowel function in patients with spinal cord injury with respect to defecation time and defecation drug dose (enema). [Subjects] Twenty-four patients with spinal cord injury participated in the study. All subjects had an incomplete injury ranging from level T8 to L2. [Methods] The subjects were randomly divided into BWSTT and RAT groups. Walking training was provided to both groups for 20 minutes, four times a week, for one month. The defecation time and enema dose were measured before and after the experiment. [Results] The RAT group showed significant shortening of defecation time and decrease of enema dose. [Conclusion] The results demonstrated that significantly better improvement in bowel function can be achieved with RAT. PMID:26157223

    Background and Aims: With the use of ultrasound, a minimal effective volume of 20 ml has been described for supraclavicular brachial plexus block. However achieving a long duration of analgesia with this minimal volume remains a challenge. We aimed to determine the effect of dexamethasone on onset and duration of analgesia in low volume supraclavicular brachial plexus block. Material and Methods: Sixty patients were randomly divided into two groups of 30 each. Group C received saline (2 ml) + 20 ml of 0.5% bupivacaine and Group D received dexamethasone (8 mg) + 20 ml of 0.5% bupivacaine in supraclavicular brachial plexus block. Hemodynamic variables and visual analog scale (VAS) score were noted at regular intervals until 450 min. The onset and duration of sensory and motor block were measured. The incidence of “Halo” around brachial plexus was observed. Student's t-test and Chi-square test were used for statistical analysis. Results: The onset of sensory and motor block was significantly earlier in dexamethasone group (10.36 ± 1.99 and 12 ± 1.64) minutes compared to control group (12.9 ± 2.23 and 18.03 ± 2.41) minutes. The duration of sensory and motor block was significantly prolonged in dexamethasone group (366 ± 28.11 and 337.33 ± 28.75) minutes compared to control group (242.66 ± 26.38 and 213 ± 26.80) minutes. The VAS score was significantly lower in dexamethasone group after 210 min. “Halo” was present around the brachial plexus in all patients in both the groups. Conclusion: Dexamethasone addition significantly increases the duration of analgesia in patients receiving low volume supraclavicular brachial plexus block. No significant side-effects were seen in patients receiving dexamethasone as an adjunct. PMID:27275056

    Background Chronic pain conditions are highly prevalent in patients with mild traumatic brain injury. Supraspinal diffuse axonal injury is known to dissociate brain functional connectivity in these patients. The effect of this dissociated state on supraspinal pain network is largely unknown. A functional magnetic resonance imaging study was conducted to compare the supraspinal pain network in patients with mild traumatic brain injury to the gender and age-matched healthy controls with the hypothesis that the functional connectivities of the medial prefrontal cortices, a supraspinal pain modulatory region to other pain-related sensory discriminatory and affective regions in the mild traumatic brain injury subjects are significantly reduced in comparison to healthy controls. Results The mild traumatic brain injury group (N = 15) demonstrated significantly (P < 0.01, cluster threshold > 150 voxels) less activities in the thalamus, pons, anterior cingulate cortex, insula, dorsolateral prefrontal cortex, and medial prefrontal cortices than the healthy control group (N = 15). Granger Causality Analyses (GCA) indicated while the left medial prefrontal cortices of the healthy control group cast a noticeable degree of outward (to affect) causality inference to multiple pain processing related regions, this outward inference pattern was not observed in the mild traumatic brain injury group. On the other hand, only patients’ bilateral anterior cingulate cortex received multiple inward (to be affected) causality inferences from regions including the primary and secondary somatosensory cortices and the inferior parietal lobe. Resting state functional connectivity analyses indicated that the medial prefrontal cortices of the mild traumatic brain injury group demonstrated a significantly (P < 0.01, F = 3.6, cluster size > 150 voxels) higher degree of functional connectivity to the inferior parietal lobe, premotor and secondary somatosensory cortex

    Purpose : The aim of this study is to examine the pattern of injuries sustained and the hospital workload generated by patients who deliberately jump from height. Method : One regional trauma centre's admissions were scrutinized to find all patients who jumped, or were suspected of jumping from one storey or greater over a four year period. Patients who died prior to admission were excluded. Results : 41 patients were included. Each patient suffered a mean of 3 injuries. The probability of calcaneal fracture was 0.32, of ankle injury 0.2, tibial fracture 0.2, femoral fracture 0.17, pelvic fracture 0.34, spinal injury 0.51, upper limb injury 0.26, head injury 0.2 and trunk injury 0.32. The mean length of inpatient stay was 7.9 days, rising to 17.9 for the 11 patients requiring intensive care. The average number of operations per patient was 1.5. Conclusion : Patients who jump from height generate large volumes of operative and inpatient workloads. Our data show that there may be a protective effect of limb trauma against lethal head, chest or pelvic injury. Injury to the upper limb is associated with a 4 times greater risk of head injury. The incidence of pelvic injury in this series is higher than in previous work. There was a high incidence of spinal fracture. Patients generated 64 surgical procedures and consumed a mean of 17.9 inpatient days, including prolonged stay in intensive care. PMID:26401162

    Background: Orbitozygomatic fracture that most commonly accompanies craniofacial injury is a challenge for medical science to reduce complications and to attain aesthetically satisfying results. Objective: To summarize our experiences with the optimum management of orbito-zygomatic fractures. Materials and Methods: This retrospective study was aimed at investigating indications and surgical approaches for orbitozygomatic fractures with clinical follow-up, particularly with regard to postoperative complications. Since 2010, 100 cases with faciomaxillary injury were assessed for Orbitozygomatic fractures with the help of physical examination, non-invasive investigations including computed tomography of the orbit. Patients were retrospectively analysed for data, such as mechanism of injury, classification of fracture, and complications. Results: Amongst 100 consecutive patients with orbito-zygomatic fractures an overwhelming majority were males (n=83). In the age distribution a great majority (45%) were in 30-45 years age group, followed by 15-30 years (22%) and 45-60 years (18%). So in the productive age group i.e. 15-60 years age group were affected mostly (85%) in our series. Among different injury mechanism, Road traffic accident affected most (69%) that landed up in orbito-zygomatic fractures followed by altercations (22%). We preferred Open reduction and internal fixation (ORIF) for 68% of the patients with orbito- zygomatic fractures, followed by closed reduction (12%). Conclusion: Ophthalmology consultation is recommended for all patients presenting with orbitozygomatic fractures, and is essential for patients with orbital blowout fractures, based on the high incidence of clinical ocular findings and injuries in this subgroup of patients.

    During axillary brachial plexus block for hand surgery, the axillary artery was accidentally punctured. After skin disinfection of the operation site a livid discoloration of the hand appeared. The initial intention of stopping surgery and performing an angiography for clarification of the suspicion of a vessel lesion was dismissed after recording the pulse at the wrist and all fingertips employing a pulsoximeter. Further investigation showed that the livid discoloration of the hand was a product of the interaction of the octenidin solution used for pre-operative hand disinfection with the polyvidone-iodine solution used for surgical skin disinfection. This case report shows that interactions of topically administered pharmaceuticals have to be taken into consideration. Lack of knowledge might lead to unnecessary and unjustified diagnostic procedures which imply additional costs and dangers for the patient. PMID:15014896

    Objective To review the literature addressing the assessment and management of pain in patients with polytraumatic injuries including traumatic brain injury (TBI) and blast-related headache, and to identify patient, clinician and systems factors associated with pain-related outcomes. Design Systematic review. Methods We conducted searches in MEDLINE of literature published from 1950 through July 2008. Due to a limited number of studies using controls or comparators, we included observational and rigorous qualitative studies. We systematically rated the quality of systematic reviews, cohort, and case-control design studies. Results One systematic review, 93 observational studies, and one qualitative research study met inclusion criteria. The literature search yielded no published studies that assessed measures of pain intensity or pain-related functional interference among patients with cognitive deficits due to TBI, that compared patients with blast-related headache with patients with other types of headache, or that assessed treatments for blast-related headache pain. Studies on the association between TBI severity and pain reported mixed findings. There was limited evidence that the following factors are associated with pain among TBI patients: severity, location, and multiplicity of injuries; insomnia; fatigue; depression; and post-traumatic stress disorder. Conclusions Very little evidence is currently available to guide pain assessment and treatment approaches in patients with polytrauma. Further research employing systematic observational as well as controlled intervention designs is clearly indicated. PMID:19818031

    We report on patients with post-traumatic fatigue and hypersomnia who showed injury of the lower portion of the ascending reticular activating system (ARAS) between the pontine reticular formation (RF) and the intralaminar thalamic nucleus (ILN) following mild traumatic brain injury (TBI), using diffusion tensor tractography (DTT).Two patients with mild TBI resulting from a car accident were enrolled in this study. Patient 1 was a 51-year-old woman showed abnormalities as 6.9 (cut off: 3.7 points) and 18 (cut off: 10) on the Fatigue Severity Scale and the Epworth Sleepiness Scale at 11 months after onset. Patient 2 was a 64-year-old woman who revealed abnormalities on the Fatigue Severity Scale and the Epworth Sleepiness Scale with 6.8 and 19 at 3 months after onset.In both patients, the upper ARAS in which the neural connectivity of the ILN to the cerebral cortex did not show significant abnormalities. However, we observed the narrowing of the left dorsal lower ARAS between the pontine RF and the ILN in both patients and the tearing (patient 1) and narrowing (patient 2) of the left ventral lower ARAS between the pontine RF and the hypothalamus.Injuries of the dorsal and ventral lower ARAS were demonstrated in patients with fatigue and hypersomnia following mild TBI. We believe that these injuries of the ARAS might be a pathogenetic mechanism of fatigue and hypersomnia in patients with TBI. PMID:26871783

    Although methylphenidate has been used as a neurostimulant to treat patients with attention deficit hyperactivity disorder, its therapeutic role in the psychomotor or cognitive recovery of patients with traumatic brain injuries (TBIs) in both intensive care and rehabilitation settings has not been adequately explored. To address this issue, this meta-analysis searched the available electronic databases using the key words "methylphenidate", "brain injuries", "head injuries", and "traumatic brain injury". Analysis of the ten double-blind RCTs demonstrated significant benefit in using methylphenidate for enhancing vigilance-associated attention (i.e., selective, sustained, and divided attention) in patients with TBIs (standardized mean difference: 0.45, 95% CI: 0.10 to 0.79), especially in sustained attention (standardized mean difference: 0.66, 95% CI: 0.22 to 1.10). However, no significant positive impact was noted on the facilitation of memory or processing speed. More studies on the efficacy and safety of methylphenidate for the cognitive improvement of patients with TBIs are warranted. PMID:26951094

    Amphotericin B deoxycholate (AmBd) is rarely used due to its adverse effect profile, which includes nephrotoxicity, infusion-related reactions, and hepatotoxicity. The incidence of hepatotoxicity related to AmBd is 18-23%, but the reports of this adverse effect are mainly in immunocompromised patients receiving chemotherapy. We report a case of AmBd-related acute hepatic injury in an immunocompetent male with multiple medical problems. The patient initially had acute hepatic injury likely caused by poor nutritional status and a diagnosis of failure to thrive, but was recovering. He was also diagnosed with bilateral renal fungal mycetomas and received systemic treatment initially with micafungin and then fluconazole after urine cultures returned with the growth of Candida glabrata. Therapy was expanded to systemic AmBd when the fungal balls persisted. The patient subsequently developed hepatic re-injury with 1 dose of AmBd, and the therapy was discontinued. Caution should be exerted when utilizing AmBd in treating patients with previous hepatic injury. PMID:27440960

    Background: Head injury presents a major worldwide social, economic, and health problem. Hyperglycemia is a significant indicator of the severity of injury and predictor of outcome, which can easily be prevented. There has been a long-standing controversy regarding the use of inhalational or intravenous (i.v.) anesthetic agents for surgery of head injury cases and impact of these agents on blood sugar level. Aims and Objectives: The aim of this study is to find out anesthetic drugs and technique having minimal or no effect on the blood sugar, and Glasgow Coma Scale (GCS) of patients with a head injury by comparing two types of anesthetic techniques in surgery of head injury patients. Materials and Methods: This was a prospective, randomized, and comparative study, conducted on 60 adult head injury patients. The patients were divided into two groups of 30 each. Group I patients received induction with sevoflurane and then had O2 + air + sevoflurane for maintenance with controlled ventilation. Group II patients received induction with i.v. propofol and then had O2 + air + propofol for maintenance with controlled ventilation. Injection fentanyl was used in both the groups at the time of induction and in intermittent boluses in maintenance. In observation, blood sugar level and mean arterial pressure were assessed at different time periods perioperatively in both groups while GCS was analyzed pre- and post-operatively. Statistical Analysis: Statistical analysis was performed by Microsoft Excel 2010 using t-test for comparison between the two groups and Z-test for comparison of proportions. Results and Conclusion: Blood sugar level was found significantly higher in patients of sevoflurane group at 30 min after induction, at the end of surgery, and 1 h after the end of anesthesia than propofol group patients. This increase of blood sugar level did not have any significant alteration in the GCS profile of the patients in sevoflurane group as compared to propofol group

    Background: Urinary tract infections (UTIs) are important causes of morbidity and mortality in patients with spinal cord injury and 22% of patients with acute spinal cord injury develop UTI during the first 50 days. Objectives: The aim of this study was to determine the prevalence, etiologic agents and risk factors for asymptomatic bacteriuria and symptomatic urinary tract infections in patients with spinal cord injury. Patients and Methods: This was a prospective investigation of spinal cord injury patients with asymptomatic bacteriuria and symptomatic urinary tract infections in Baskent University Medical Faculty Ayas Rehabilitation Center and Ankara Physical Therapy and Rehabilitation Center between January 2008 and December 2010. The demographic status, clinical and laboratory findings of 93 patients with spinal cord injury were analyzed in order to determine the risk factors for asymptomatic or symptomatic bacteriuria Results: Sixty three (67.7%) of 93 patients had asymptomatic bacteriuria and 21 (22.6%) had symptomatic urinary tract infection. Assessment of the frequency of urinary bladder emptying methods revealed that 57 (61.3%) of 93 patients employed permanent catheters and 24 (25.8%) employed clean intermittent catheterization. One hundred and thirty-five (48.0%) of 281 strains isolated form asymptomatic bacteriuria attacks and 16 (66.6%) of 24 strains isolated from symptomatic urinary tract infection attacks, totaling 151 strains, had multidrug resistance (P > 0.05). One hundred (70.4%) of 142 Escherichia coli strains and 19 (34.5%) of 55 Klebsiella spp strains proliferated in patients with asymptomatic bacteriuria; 8 (80%) of 10 E. coli strains and 4 (80%) of 5 Klebsiella spp. strains were multidrug resistant. Conclusions: The most common infectious episode among spinal cord injury patients was found to be urinary tract ınfection. E. coli was the most common microorganism isolated from urine samples.

    2016-01-01

    Background Recently, ultrasound has been commonly used. Ultrasound-guided interscalene brachial plexus block (IBPB) by posterior approach is more commonly used because anterior approach has been reported to have the risk of phrenic nerve injury. However, posterior approach also has the risk of causing nerve injury because there are risks of encountering dorsal scapular nerve (DSN) and long thoracic nerve (LTN). Therefore, the aim of this study was to evaluate the risk of encountering DSN and LTN during ultrasound-guided IBPB by posterior approach. Methods A total of 70 patients who were scheduled for shoulder surgery were enrolled in this study. After deciding insertion site with ultrasound, awake ultrasound-guided IBPB with nerve stimulator by posterior approach was performed. Incidence of muscle twitches (rhomboids, levator scapulae, and serratus anterior muscles) and current intensity immediately before muscle twitches disappeared were recorded. Results Of the total 70 cases, DSN was encountered in 44 cases (62.8%) and LTN was encountered in 15 cases (21.4%). Both nerves were encountered in 10 cases (14.3%). Neither was encountered in 21 cases (30.4%). The average current measured immediately before the disappearance of muscle twitches was 0.44 mA and 0.50 mA at DSN and LTN, respectively. Conclusions Physicians should be cautious on the risk of injury related to the anatomical structures of nerves, including DSN and LTN, during ultrasound-guided IBPB by posterior approach. Nerve stimulator could be another option for a safer intervention. Moreover, if there is a motor response, it is recommended to select another way to secure better safety. PMID:27413483

    Objective It has been suggested that fluid accumulation may delay recognition of acute kidney injury (AKI). We sought to determine the impact of fluid balance on the incidence of non-dialysis requiring AKI in patients with acute lung injury and to describe associated outcomes, including mortality. Design Analysis of the Fluid and Catheter Treatment Trial, a factorial randomized clinical trial of conservative versus liberal fluid management and of management guided by a central venous versus pulmonary artery catheter. Setting and Patients 1000 patients at ARDS Network hospitals. Measurements and Main Results The incidence of AKI, defined as an absolute rise in creatinine of ≥ 0.3 mg/dL or a relative change of > 50% over 48 hours, was examined before and after adjustment of serum creatinine for fluid balance. The incidence of AKI before adjustment for fluid balance was greater in those managed with the conservative fluid protocol (57 versus 51%, p = 0.04). After adjustment for fluid balance, the incidence of AKI was greater in those managed with the liberal fluid protocol (66 versus 58%, p = 0.007). Patients who met AKI criteria after adjustment of creatinine for fluid balance (but not before) had a mortality rate that was significantly greater than those who did not meet AKI criteria both before and after adjustment for fluid balance (31 versus 12%, p < 0.001) and those who had AKI before but not after adjustment for fluid balance (31 versus 11%, p = 0.005). The mortality of those patients meeting AKI criteria after but not before adjustment for fluid balance was similar to patients with AKI both before and after adjustment for fluid balance (31% versus 38%, p = 0.18). Conclusions Fluid management influences serum creatinine and therefore the diagnosis of AKI using creatinine-based definitions. Patients with “unrecognized” AKI that is identified after adjusting for positive fluid balance have high mortality rates, and patients who have AKI before but not after

    The patient was a 23-year-old man, currently serving in a military airborne operations unit. During a jump training exercise, the patient's right lower extremity became entangled in his parachute equipment upon exiting the aircraft, which caused hyperextension and valgus forces upon his right knee. Due to concern for a fracture, the patient was transported to an emergency department, where conventional radiographs were completed and interpreted by a radiologist as negative for a fracture. Following further physical examination by a physical therapist, magnetic resonance imaging of the right knee was ordered, revealing ruptures of the anterior cruciate ligament and medial collateral ligament.

    Patients with spinal cord injuries suffer not only from sensory and motor deficits, but from failure of the autonomic nerve system which in consequence involves many organs and metabolic pathways. These deficits lead to a different approach to these patients and their medical, psychological and social problems. Three examples will illustrate the different approaches to typical medical problems of these patients. Regularly ambulatory long term follow up visits in specialized centres in close collaboration with general practitioners help to diminish complications and rehospitalisations. Facing the now ageing population with a spinal cord injury we need evidence based guidelines in follow up and preventive strategies for these patients. We updated these recommendations recently.

    OBJECTIVE: The effects of interleukin (IL)-6 in the injured patient are examined in an attempt to clarify the potential pathophysiologic role of IL-6 in the response to injury. SUMMARY BACKGROUND DATA: Interleukin-6 is an integral cytokine mediator of the acute phase response to injury and infection. However, prolonged and excessive elevations of circulating IL-6 levels in patients after trauma, burns, and elective surgery have been associated with complications and mortality. The mechanistic role of IL-6 in mediating these effects is unclear. METHODS: A review of current literature is performed to summarize the origins, mechanisms of action, and biologic effects of IL-6 and to characterize the IL-6 response to injury. RESULTS: Interleukin-6 is a multifunctional cytokine expressed by a variety of cells after a multitude of stimuli, under complex regulatory control mechanisms. The IL-6 response to injury is uniquely consistent and related to the magnitude of the insult. Moreover, the early postinjury IL-6 response correlates with complications as well as mortality. CONCLUSIONS: Interleukin-6 appears to play an active role in the postinjury immune response, making it an attractive therapeutic target in attempts to control hyperinflammatory provoked organ injury.

    Unsuccessful anesthesia of the inferior alveolar nerve (IAN) may be due to supplementary innervations of mandibular molars from other branches, namely the cervical plexus (CP). The purpose of this prospective, randomized, double-blind, controlled trial was to determine the effectiveness of an intraoral cervical plexus anesthetic technique (ICPAT) in mandibular molars with symptomatic irreversible pulpitis (SIR) when the IAN and lingual nerve (LN) blocks failed, and to provide a description of the technique. Forty patients diagnosed with SIR received IAN and LN block anesthesia prior to treatment. After clinical signs of anesthesia, patients were subjected to an electrical pulp test (EPT) at 2-min cycles for 10 min post-injection. The anesthesia was considered unsuccessful if there was a positive EPT response ten minutes following profound lip numbness. The experimental group (n = 20) were administered 2% Lidocaine with 1:100,000 epinephrine using the ICPAT. The control group (n = 20) were administered 0.9% sterile saline using the ICPAT. Success was defined as no response on two consecutive readings from an EPT. In the experimental group, 60% of subjects showed successful anesthesia, whereas none of the subjects in the control group had successful anesthesia. A multiple logistic regression analysis showed that the anesthesia success rate using the ICPAT method was significantly higher (P < 0.05) than in the control group, irrespective of molar tooth type. The ICPAT method may be useful as a supplementary anesthetic technique for mandibular molars with SIR in subjects whom the IAN and LN blocks do not provide adequate anesthesia. PMID:25864872

    Objective: To assess the use and clinical impact of tracheostomy in burn patients. Summary Background Data: The role of tracheostomy in the management of burn patients is controversial, with only a few recent studies conducted in this population. Methods: Retrospective study of all adult burn patients who underwent a tracheostomy in a Burns Unit between 1995 and 2013. These were compared with a control group (1:1) who underwent orotracheal intubation. Hospital records were reviewed to obtain demographic and clinical information, including those related to respiratory support and tracheostomy. The McNemar's Chi-square and Signed-Rank Tests were used to study differences in morbimortality between both groups. Results: A total of n = 20 patients underwent tracheostomy (0.9% of admissions, 56.0 ± 19.5 years, 60.0% women). The most common indication was long-term ventilation (75%), 24.6 ± 19.7 days after admission. Thirteen patients were successfully decannulated with a fatal complication observed in one case. Patients in the tracheostomy group were found to require longer-term mechanical ventilation (43.2 vs. 20.4 days; P = 0.004), with no differences in respiratory infection rates (30.0% vs. 31.6%; P = 0.687) or mortality (30.0% vs. 42.1%; P = 0.500). Ventilator weaning times (15.7 vs. 3.3 days; P = 0.001) and hospital stays (99.1 vs. 53.1 days; P = 0.030) were longer in the tracheostomy group, with no differences in duration of sedation. Conclusions: Tracheostomy may be a safe procedure in burn patients and is not associated with higher rates of mortality or respiratory infection. Tracheostomy patients showed longer mechanical ventilation times and higher morbidity, probably not attributable to tracheostomy. PMID:26321803

    Background: Trauma is a leading cause of morbidity and mortality among individuals under 40 and is the third main cause for death throughout the world. Objectives: This study was designed to compare our modified injury scoring systems with the current injury severity score (ISS) from the viewpoint of its predictive value to estimate the duration of hospitalization in trauma patients. Patients and Methods: This analytical cross-sectional study was performed at the general referral trauma center of Bandar-Abbas in southern Iran from March 2009 to March 2010. The study population consisted of all the trauma patients referred to the emergency department (ED). Demographic data, type and severity of injury, duration of admission, Glasgow coma scale (GCS), and revised trauma score (RTS) were recorded. The injury severity score (ISS) and NISS were calculated. The length of hospital stay was recorded during the patients follow-up and compared with ISS, NISS and modified injury scoring systems. Results: Five hundred eleven patients (446 males (87.3%) and 65 females (12.7%)) were enrolled in the study. The mean age was 22 ± 4.2 for males and 29.15 ± 3.8 for females. The modified NISS had a relatively strong correlation with the length of hospitalization (r = 0.79). The formula below explains the length of hospitalization according to MNISS score. Duration of hospitalization was 0.415 + (2.991) MNISS. Duration of hospitalization had a strong correlation with MISS (r = 0.805, R2: 0.65). Duration of hospitalization was 0.113 + (7.915) MISS. Conclusions: This new suggested scale shows a better value to predict patients’ length of hospital stay compared to ISS and NISS. However, future studies with larger sample sizes and more confounding factors such as prehospital procedures, intubation and other procedures during admission, should be designed to examine these scoring systems and confirm the results of our study.

    Masha'al, Dina A.

    There is a high prevalence in malnutrition among traumatic brain injury (TBI) due to the hypermetabolism and hypercatabolism which develop post injury. Traumatic brain injury patients are different, even among themselves, in their energy requirements and response to nutritional therapy. This implies that there are other factors that affect the energy intake of these patients and enhance the incidence of malnutrition. This dissertation study examines the nutritional status of TBI patients upon admission to the intensive care unit (ICU) and during their hospital stay to describe baseline status, detect changes in nutritional status over 7 days, and identify the factors affecting the adequacy of energy intake and the change in nutritional status as a consequence. Anthropometric measurements, biomedical measurements, measures of severity of illness, daily health status, level of brain injury severity, and other data were collected from the medical records of 50 patients, who were ≥ 18 years old, mechanically ventilated in the first 24 hours of ICU admission, and had a Glasgow Coma Scale score between 3-12. These data were used to examine the previous relationships. Although there was no statistically significant change found in body mass index and weight, there was a significant change detected in other nutritional markers, including hemoglobin, albumin, and total lymphocyte levels over the 7 days of ICU and hospital stay. No significant relationship was found between the adequacy of energy intake and total prescribed energy, severity of illness, level of brain injury severity, daily health status, patient age, intracranial pressure, or time of feeding initiation. Findings may be used to develop and test interventions to improve nutritional status during the acute phase of TBI. This will lay a foundation for health care providers, including nurses, to establish standards for practice and nutrition protocols to assure optimal nutrition assessment and intervention in a

    Background: Electrical burn is less prevalent in comparison to other forms of burn injuries, however this type of injury is considered as one of the most devastating due to high morbidity and mortality. Understanding the epidemiologic pattern of electrical burns helps determine the contributing factors leading to this type of injury. Objectives: Epidemiologic studies on electrical burn are scarce in Iran. This study was conducted to evaluate electrical burn injury at our center. Materials and Methods: Demographic data, etiology, burn percentage and other measures related to electrical burn injury of 682 electrical burn patients treated from 2007 to 2011 were collected and analyzed. Results: We assessed 682 electrical burn patients (~10.8% of all burn patients); the mean age was 29.4 years and 97.8% were males. The mean hospital stay was 18.5 days and the mean burn extent was 14.43%. Severe morbidities caused 17 (2.5%) deaths. Amputation was performed in 162 cases. The most common amputation site was the fingers (35%). Most victims were workers and employees and 68.5% of electrical burns occurred at their workplace; 72% of electrical burns were due to high voltage electrical current (more than 1000 V). There was a correlation between voltage and amputation (P = 0.001) and also between voltage and fasciotomy (P = 0.033), but there was no correlation between voltage and mortality (P = 0.131) Conclusions: Electrical burn injuries are still amongst the highest accident-related morbidities and mortalities. Educating the population about the dangers and hazards associated with improper use of electrical devices and instruments is imperative. PMID:25717451

    Traumatic brain injury contributes significantly to military combat morbidity and mortality. No longer maintaining comprehensive medical care facilities throughout the world, the US military developed a worldwide trauma care system making the patient the moving part of the system. Life-saving interventions are performed early, and essential care is delivered at forward locations. Patients then proceed successively through increasingly capable levels of care culminating with arrival in the US. Proper patient selection and thorough mission preparation are crucial to the safe and successful intercontinental aeromedical evacuation of critical brain-injured patients during Operations Iraqi Freedom and Enduring Freedom.

    In a prospective controlled trial to compare conventional interscalene brachial plexus block (ISBPB) using anatomic landmarks and electro-stimulation with a combined technique of ultrasound guidance followed by nerve stimulation, 60 patients were randomized into 2 matched equal groups: Group A using nerve stimulation (NS) alone and Group B using the combination of ultrasound and NS. The time to detect the plexus (3.9 ± 4 min in Group A and 3.3 ± 1.4 min in Group B) was not significantly different. We needed to reposition the needle once (n = 13) or twice (n = 4) in Group B. First-shot motor response was achieved in all but one patient in Group A; here we were only able to locate the plexus by use of ultrasound. None of the patients needed general anaesthesia. There were no significant differences between postoperative pain, motor power, or patient's satisfaction. ISBPB seems similarly effective using electro-stimulation and ultrasound if performed by experienced anesthesiologists. PMID:22391670

    Objective To determine whether EEG spectral analysis could be used to demonstrate awareness in patients with severe brain injury. Methods We recorded EEG from healthy controls and three patients with severe brain injury, ranging from minimally conscious state (MCS) to locked-in-state (LIS), while they were asked to imagine motor and spatial navigation tasks. We assessed EEG spectral differences from 4 to 24 Hz with univariate comparisons (individual frequencies) and multivariate comparisons (patterns across the frequency range). Results In controls, EEG spectral power differed at multiple frequency bands and channels during performance of both tasks compared to a resting baseline. As patterns of signal change were inconsistent between controls, we defined a positive response in patient subjects as consistent spectral changes across task performances. One patient in MCS and one in LIS showed evidence of motor imagery task performance, though with patterns of spectral change different from the controls. Conclusion EEG power spectral analysis demonstrates evidence for performance of mental imagery tasks in healthy controls and patients with severe brain injury. Significance EEG power spectral analysis can be used as a flexible bedside tool to demonstrate awareness in brain-injured patients who are otherwise unable to communicate. PMID:21514214

    Objective To investigate the effect of botulinum toxin type A (BTA) injection into the salivary gland and to evaluate the changes of drooling in varied postures in tetraplegic patients with brain injury. Methods Eight tetraplegic patients with brain injury were enrolled. BTA was injected into each parotid and submandibular gland of both sides under ultrasonographic guidance. Drooling was measured by a questionnaire-based scoring system for drooling severity and frequency, and the sialorrhea was measured by a modified Schirmer test for the patients before the injection, 3 weeks and 3 months after the injection. Drooling was evaluated in each posture, such as supine, sitting, and tilt table standing, and during involuntary mastication, before and after the injection. Results The severity and frequency of drooling and the modified Schirmer test improved significantly at 3 weeks and 3 months after the injection (p<0.05). Drooling was more severe and frequent in tilt table standing than in the sitting position and in sitting versus supine position (p<0.05). The severity of drooling was significantly increased in the patients with involuntary mastication (p<0.05). Conclusion Salivary gland injection of BTA in patients with tetraplegia resulting from brain injury who had drooling and sialorrhea could improve the symptoms for 3 months without complications. The severity and frequency of drooling were dependent on posture and involuntary mastication. Proper posture and involuntary mastication of the patients should be taken into account in planning drooling treatment. PMID:24466514

    2005-12-01

    Traditionally, patients are rarely seen as partners in health research; their influence on priority setting, research design, the undertaking of research, and interpretation and dissemination of findings was marginal. Nowadays, health researchers, funding agencies, governments, and patient organizations are beginning to acknowledge that the passive role of patients in health research is no longer satisfactory. The emerging commitment and consensus concerning the aims and features of patient participation in research have created a need for an appropriate method to engage patients as partners in health research. In this article, the author argues that a responsive-constructivist approach to evaluation fits with the aims and features of patient participation. She illustrates its potential with a case example that concerns a dialogue among patients and (clinical) researchers in the field of spinal cord injuries. She reflects on learning experiences and the (un)expected difficulties and potentials in creating social conditions for patient participation in health research. PMID:16263914

    Collaborative care interventions show significant promise in facilitating integrative care, which addresses the physical and mental health needs of patients with orofacial trauma. Ensuring the successful implementation of collaborative care interventions depends on having an adequate understanding of the potential barriers to the provision and receipt of mental health services within specific clinical settings. This article reviews recent findings on the patients' and providers' perceptions of barriers to psychosocial aftercare services in oral and maxillofacial trauma care settings. These findings indicate that although patients and providers recognize the need for psychosocial aftercare, they report substantial barriers to these services. Structural barriers, such as not knowing where to obtain services and financial cost, are the major obstacles among patients. Among providers, structural barriers also serve as significant impediments to the provision of psychosocial services. Some of the most common structural barriers reported by providers include a shortage of financial resources, trained clinical staff, and space. Although collaborative care interventions may be well suited to capitalize on patients' and providers' interests in psychosocial aftercare programs, further research is needed to determine the viability of this promising aftercare model within oral and maxillofacial trauma care settings.

    Objective Age is a strong predictor of mortality in traumatic brain injuries. A surgical decision making is difficult especially for the elderly patients with severe head injuries. We studied so-called 'withholding a life-saving surgery' over a two year period at a university hospital. Methods We collected data from 227 elderly patients. In 35 patients with Glasgow Coma Score 3-8, 28 patients had lesions that required operation. A life-saving surgery was withheld in 15 patients either by doctors and/or the families (Group A). Surgery was performed in 13 patients (Group B). We retrospectively examined the medical records and radiological findings of these 28 patients. We calculated the predicted probability of 6 month mortality (IPM) and 6 month unfavorable outcome (IPU) to compare the result of decision by the International Mission for Prognosis and Analysis of Clinical Trials in TBI (IMPACT) calculator. Results Types of the mass lesion did not affect on the surgical decision making. None of the motor score 1 underwent surgery, while all patients with reactive pupils underwent surgery. Causes of injury or episodes of hypoxia/hypotension might have affected on the decision making, however, their role was not distinct. All patients in the group A died. In the group B, the outcome was unfavorable in 11 of 13 patients. Patients with high IPM or IPU were more common in group A than group B. Wrong decisions brought futile cares. Conclusion Ethical training and developing decision-making skills are necessary including shared decision making. PMID:25024822

    The goal of this study was to examine effects of vasoactive stimuli on blood flow to choroid plexus. The authors used microspheres to measure blood flow to choroid plexus and cerebrum in anesthetized dogs and rabbits. A critical assumption of the microsphere method is that microspheres do not pass through arteriovenous shunts. Blood flow values obtained with simultaneous injection of 15- and 50-{mu}m microspheres were similar, which suggest that shunting of 15-{mu}m microspheres was minimal. Blood flow to choroid plexus under control conditions was 287 {plus minus} 26 (means {plus minus} SE) ml {center dot} min{sup {minus}1} {center dot} 100 g{sup {minus}1} in dogs and 385 {plus minus} 73 ml {center dot} min{sup {minus}1} 100 g{sup {minus}1} in rabbits. Consecutive measurements under control conditions indicated that values for blood flow are reproducible. Adenosine did not alter blood flow to cerebrum but increased blood flow to choroid plexus two- to threefold in dogs and rabbits. Norepinephrine and phenylephrine did not affect blood flow to choroid plexus and cerebrum but decreased blood flow to choroid plexus by {approx} 50%. The authors suggest that (1) the microsphere method provides reproducible valid measurements of blood flow to the choroid plexus in dogs and rabbits and (2) vasoactive stimuli may have profoundly different effects on blood flow to choroid plexus and cerebrum.

  19. The choroid plexuses and their impact on developmental neurogenesis

    PubMed Central

    2014-01-01

    During brain development the neural stem cells are regulated by both intrinsic and extrinsic sources. One site of origin of extrinsic regulation is the developing choroid plexuses, primely situated inside the cerebral ventricles. The choroid plexuses are very active in terms of both secretion and barrier function as soon as they appear during development and control the production and contents of cerebrospinal fluid (CSF). This suggests that regulated secretion of signaling molecules from the choroid plexuses into CSF can regulate neural stem cell behavior (as they are in direct contact with CSF) and thereby neurogenesis and brain development. Here, choroid plexus development, particularly with regards to molecular regulation and specification, is reviewed. This is followed by a review and discussion of the role of the developing choroid plexuses in brain development. In particular, recent evidence suggests a region-specific reciprocal regulation between choroid plexuses and the neural stem cells. This is accomplished by site-specific secretion of signaling molecules from the different choroid plexuses into CSF, as well as brain region specific competence of the neural stem cells to respond to the signaling molecules present in CSF. In conclusion, although in its infancy, the field of choroid plexus regulation of neurogenesis has already and will likely continue to shed new light on our understanding of the control and fine-tuning of overall brain development.

    Background: The spinal cord injured patients if congregated early in spinal units where better facilities and dedicated expert care exist the outcome of treatment and rehabilitation, can be improved. The objective of this study is to find out the various factors responsible for a delay in the presentation of spinal injury patients to the specialized spinal trauma units and to suggest steps to improve the quality of care of the spinal trauma patients in the Indian setup. Materials and Methods: Sixty patients of traumatic spinal cord injury admitted for rehabilitation between August 2005 and May 2006 were enrolled into the study and their data was analyzed. Results: Eighty-five per cent of the spinal cord injured patients were males and the mean age was 34 years (range 13-56 years). Twenty-nine (48.33%) of the spinal injuries occurred due to fall from height. There was an average of 45 days (range 0-188 days) of delay in presentation to a specialized spinal unit and most of the time the cause for the delay was unawareness on the part of patients and/or doctors regarding specialized spinal units. In 38 (62.5%) cases the mode of transportation of the spinal cord injured patient to the first visited hospital was by their own conveyance and the attendants of the patients did not have any idea about precautions essential to prevent neurological deterioration. Seventeen (28.33%) patients were given injection solumedrol with conservative treatment, 35 (60%) patients were given only conservative treatment and seven patients were operated (11.66%) upon at initially visited hospital. Of the seven patients operated five were fixed with posterior Harrington instrumentation (71.42%) and two (28.57%) were operated by short segment posterior pedicle screw fixation. None of the patients were subjected to physiotherapy-assisted transfers or wheel chair skills or even basic postural training, proper bladder/ bowel training program and sitting balance.

    Objective This study aimed to describe and compare the characteristics and clinical outcomes of patients with septic and non-septic acute kidney injury. Methods This study evaluated an open cohort of 117 critically ill patients with acute kidney injury who were consecutively admitted to an intensive care unit, excluding patients with a history of advanced-stage chronic kidney disease, kidney transplantation, hospitalization or death in a period shorter than 24 hours. The presence of sepsis and in-hospital death were the exposure and primary variables in this study, respectively. A confounding analysis was performed using logistic regression. Results No significant differences were found between the mean ages of the groups with septic and non-septic acute kidney injury [65.30±21.27 years versus 66.35±12.82 years, respectively; p=0.75]. In the septic and non-septic acute kidney injury groups, a predominance of females (57.4% versus 52.4%, respectively; p=0.49) and Afro-descendants (81.5% versus 76.2%, respectively; p=0.49) was observed. Compared with the non-septic patients, the patients with sepsis had a higher mean Acute Physiology and Chronic Health Evaluation II score [21.73±7.26 versus 15.75±5.98; p<0.001)] and a higher mean water balance (p=0.001). Arterial hypertension (p=0.01) and heart failure (p<0.001) were more common in the non-septic patients. Septic acute kidney injury was associated with a greater number of patients who required dialysis (p=0.001) and a greater number of deaths (p<0.001); however, renal function recovery was more common in this group (p=0.01). Sepsis (OR: 3.88; 95%CI: 1.51-10.00) and an Acute Physiology and Chronic Health Evaluation II score >18.5 (OR: 9.77; 95%CI: 3.73-25.58) were associated with death in the multivariate analysis. Conclusion Sepsis was an independent predictor of death. Significant differences were found between the characteristics and clinical outcomes of patients with septic versus non-septic acute kidney

    Acute kidney injury (AKI) is characterized by an abrupt decline in renal function, resulting in an inability to secrete waste products and maintain electrolyte and water balance, and is associated with high risks of morbidity and mortality. This study retrospectively analyzed clinical data, treatment, and prognosis of 271 hospitalized patients (172 males and 99 females) diagnosed with AKI from December, 2008 to December, 2011. In addition, this study explored the association between the cause of AKI and prognosis, severity and treatment of AKI. The severity of AKI was classified according to the Acute Kidney Injury Network (AKIN) criteria. Renal recovery was defined as a decrease in a serum creatinine level to the normal value. Prerenal, renal, and postrenal causes accounted for 36.5% (99 patients), 46.5% (126 patients) and 17.0% (46 patients), respectively, of the incidence of AKI. Conservative, surgical, and renal replacement treatments were given to 180 (66.4%), 30 (11.1%) and 61 patients (22.5%), respectively. The overall recovery rate was 21.0%, and the mortality rate was 19.6%. Levels of Cl(-), Na(+) and carbon dioxide combining power decreased with increasing severity of AKI. Cause and treatment were significantly associated with AKI prognosis. Likewise, the severity of AKI was significantly associated with cause, treatment and prognosis. Multivariate logistic regression analysis found that respiratory injury and multiple organ dysfunction syndrome (MODS) were associated with AKI patient death. Cause, treatment and AKIN stage are associated with the prognosis of AKI. Respiratory injury and MODS are prognostic factors for death of AKI patients. PMID:24586237

    Objective To assess the effectiveness of the resting foot splint to prevent ankle contracture. Methods We performed a randomized controlled trial in 33 patients with brain injury with ankle dorsiflexor weakness (muscle power ≤grade 2). Both groups continued conventional customized physical therapy, but the patients in the foot splint group were advised to wear a resting foot splint for more than 12 hours per day for 3 weeks. The data were assessed before and 3 weeks after the study. The primary outcome was the change in ankle dorsiflexion angle after 3 weeks. Results Before the study, there were no differences between groups in gender, age, time post-injury, brain injury type, initial edema, spasticity, passive range of ankle dorsiflexion, Fugl-Meyer score (FMS), or Functional Ambulation Classification. A significant improvement in ankle dorsiflexion angle, and FMS was found after 3 weeks in both groups. The splint group showed more spasticity than the control group after 3 weeks (p=0.04). The change of ankle dorsiflexion angle, foot circumference, spasticity, and FMS after adjusting initial value and spasticity were not significantly different between the 2 groups. Conclusion Wearing a resting foot splint for 3 weeks did not affect joint mobility in patients with subacute brain injury regularly attending personalized rehabilitation programs. Further studies of larger sample sizes with well controlled in spasticity are required to evaluate the effects of the resting foot splint. PMID:26949680

    Acute kidney injury (AKI) is common after hematopoietic cell transplant (HCT). The etiology of AKI is unknown because biopsies are rarely performed. The pathophysiology of injury is inferred from clinical data. Thrombotic microangiopathy (TMA) is often invoked as the cause of renal injury. Patients >2 years old undergoing their first HCT at Fred Hutchinson Cancer Research Center participated in this study. We prospectively measured plasma markers of coagulation activation, (PAI-1 and tPA) and fibrinolyis (D-dimer) weekly in 149 patients during the first 100 days post transplant. Cox proportional hazards modeling was used to determine associations between these markers and AKI (doubling of baseline serum creatinine). Kruskal-Wallis test was used to determine the associations between day 100 urinary albumin to creatinine ratios and these markers. Thirty one percent of patients developed AKI. Though elevations in these markers occurred frequently, neither PAI-1 nor tPA were associated with the development of AKI. D-dimer was associated with a slightly increased risk of AKI (relative risk=1.76; P-value 0.04). None of these markers were associated with micro- or macroalbuminuria at day 100. The lack of an association with AKI suggests that endothelial injury in the form of TMA is not a common cause of AKI early after transplant. PMID:25665045

    Vertebral artery injuries due to cervical spine trauma, although rarely described in the literature, are relatively common. While most of them will remain asymptomatic, a small percentage of patients may suffer life threatening complications. We report a case of the right vertebral artery injury in a patient with fracture of C4 vertebra, successfully treated with endovascular approach. A 78-year-old male patient was hospitalized for cervical spine injury caused by falling off the tractor. Radiological assessment revealed fracture of C4 vertebra with proximal two-thirds of C4 body dislocated five millimeters dorsally. Significant swelling of soft prevertebral tissues distally of C2 segment was also present. During emergency surgery using standard anterior approach for cervical spine, excessive bleeding started from the injured right vertebral artery. Bleeding was stopped by tamponade with oxidized regenerated cellulose sheet and C4-C5 anterior fixation; then partial reduction of displacement was done. Fifteen days later, after angiography, endovascular repair of the right vertebral artery was performed using percutaneous stent graft. Follow up computed tomography scan angiography showed valid stent patency without contrast extravasation. In cases of cervical spine trauma, surgeon should always be prepared to manage injury of vertebral artery. Bleeding can primarily be stopped by hemostatic packing, and definitive repair can be successfully achieved by endovascular approach using percutaneous stent graft. PMID:25509251

    Acute kidney injury (AKI) is common after hematopoietic cell transplant (HCT). The etiology of AKI is unknown because biopsies are rarely performed. The pathophysiology of injury is inferred from clinical data. Thrombotic microangiopathy (TMA) is often invoked as the cause of renal injury. Patients > 2 years undergoing their first HCT at Fred Hutchinson Cancer Research Center (FHCRC) participated in this study. We prospectively measured plasma markers of coagulation activation, (PAI-1 and tPA) and fibrinolyis (D-dimer) weekly in 149 patients during the first 100 days post-transplant. Cox proportional hazards modeling was used to determine associations between these markers and AKI (doubling of baseline serum creatinine). Kruskal-Wallis test was used to determine associations between day 100 urinary albumin to creatinine ratios (ACR) and these markers. Thirty one percent of patients developed AKI. Though elevations in these markers occurred frequently, neither PAI-1 nor tPA were associated with development of AKI. D-dimer was associated with a slightly increased risk of AKI (RR=1.76; p-value 0.04). None of these markers were associated with micro- or macroalbuminuria at day 100. The lack of an association with AKI suggests that endothelial injury in the form of TMA is not a common cause of AKI early after transplant. PMID:25665045

    2008-01-01

    Objective To develop and validate practical prognostic models for death at 14 days and for death or severe disability six months after traumatic brain injury. Design Multivariable logistic regression to select variables that were independently associated with two patient outcomes. Two models designed: “basic” model (demographic and clinical variables only) and “CT” model (basic model plus results of computed tomography). The models were subsequently developed for high and low-middle income countries separately. Setting Medical Research Council (MRC) CRASH Trial. Subjects 10 008 patients with traumatic brain injury. Models externally validated in a cohort of 8509. Results The basic model included four predictors: age, Glasgow coma scale, pupil reactivity, and the presence of major extracranial injury. The CT model also included the presence of petechial haemorrhages, obliteration of the third ventricle or basal cisterns, subarachnoid bleeding, midline shift, and non-evacuated haematoma. In the derivation sample the models showed excellent discrimination (C statistic above 0.80). The models showed good calibration graphically. The Hosmer-Lemeshow test also indicated good calibration, except for the CT model in low-middle income countries. External validation for unfavourable outcome at six months in high income countries showed that basic and CT models had good discrimination (C statistic 0.77 for both models) but poorer calibration. Conclusion Simple prognostic models can be used to obtain valid predictions of relevant outcomes in patients with traumatic brain injury. PMID:18270239

    Background: Contrast-enhanced whole-body computed tomography (also called “pan-scanning”) is considered to be a conclusive diagnostic tool for major trauma. We sought to determine the accuracy of this method, focusing on the reliability of negative results. Methods: Between July 2006 and December 2008, a total of 982 patients with suspected severe injuries underwent single-pass pan-scanning at a metropolitan trauma centre. The findings of the scan were independently evaluated by two reviewers who analyzed the injuries to five body regions and compared the results to a synopsis of hospital charts, subsequent imaging and interventional procedures. We calculated the sensitivity and specificity of the pan-scan for each body region, and we assessed the residual risk of missed injuries that required surgery or critical care. Results: A total of 1756 injuries were detected in the 982 patients scanned. Of these, 360 patients had an Injury Severity Score greater than 15. The median length of follow-up was 39 (interquartile range 7–490) days, and 474 patients underwent a definitive reference test. The sensitivity of the initial pan-scan was 84.6% for head and neck injuries, 79.6% for facial injuries, 86.7% for thoracic injuries, 85.7% for abdominal injuries and 86.2% for pelvic injuries. Specificity was 98.9% for head and neck injuries, 99.1% for facial injuries, 98.9% for thoracic injuries, 97.5% for abdominal injuries and 99.8% for pelvic injuries. In total, 62 patients had 70 missed injuries, indicating a residual risk of 6.3% (95% confidence interval 4.9%–8.0%). Interpretation: We found that the positive results of trauma pan-scans are conclusive but negative results require subsequent confirmation. The pan-scan algorithms reduce, but do not eliminate, the risk of missed injuries, and they should not replace close monitoring and clinical follow-up of patients with major trauma. PMID:22392949

    OBJECT Studies of preclinical spinal cord injury (SCI) in rodents indicate that expansion of intramedullary lesions (IMLs) seen on MR images may be amenable to neuroprotection. In patients with subaxial SCI and motor-complete American Spinal Injury Association (ASIA) Impairment Scale (AIS) Grade A or B, IML expansion has been shown to be approximately 900 μm/hour. In this study, the authors investigated IML expansion in a cohort of patients with subaxial SCI and AIS Grade A, B, C, or D. METHODS Seventy-eight patients who had at least 2 MRI scans within 6 days of SCI were enrolled. Data were analyzed by regression analysis. RESULTS In this cohort, the mean age was 45.3 years (SD 18.3 years), 73 patients were injured in a motor vehicle crash, from a fall, or in sport activities, and 77% of them were men. The mean Injury Severity Score (ISS) was 26.7 (SD 16.7), and the AIS grade was A in 23 patients, B in 7, C in 7, and D in 41. The mechanism of injury was distraction in 26 patients, compression in 22, disc/osteophyte complex in 29, and Chance fracture in 1. The mean time between injury onset and the first MRI scan (Interval 1) was 10 hours (SD 8.7 hours), and the mean time to the second MRI scan (Interval 2) was 60 hours (SD 29.6 hours). The mean IML lengths of the first and second MR images were 38.8 mm (SD 20.4 mm) and 51 mm (SD 36.5 mm), respectively. The mean time from the first to the second MRI scan (Interval 3) was 49.9 hours (SD 28.4 hours), and the difference in IML lengths was 12.6 mm (SD 20.7 mm), reflecting an expansion rate of 366 μm/ hour (SD 710 μm/hour). IML expansion in patients with AIS Grades A and B was 918 μm/hour (SD 828 μm/hour), and for those with AIS Grades C and D, it was 21 μm/hour (SD 304 μm/hour). Univariate analysis indicated that AIS Grade A or B versus Grades C or D (p < 0.0001), traction (p= 0.0005), injury morphology (p < 0.005), the surgical approach (p= 0.009), vertebral artery injury (p= 0.02), age (p < 0.05), ISS (p < 0

    The aim of this paper is to investigate medical efforts and injury profiles of victims of the Lushan earthquake admitted to three military hospitals. This study retrospectively investigated the clinical records of 266 admitted patients evacuated from the Lushan earthquake area. The 2005 version of the Abbreviated Injury Scale (AIS-2005) was used to identify the severity of each injury. Patient demographic data, complaints, diagnoses, injury types, prognosis, means of transportation, and cause of injury were all reviewed individually. The statistical analysis of the study was conducted primarily using descriptive statistics. Of the 266 patients, 213 (80.1%) were admitted in the first two days. A total of 521 injury diagnoses were recorded in 266 patients. Earthquake-related injuries were primarily caused by buildings collapsing (38.4%) and victims being struck by objects (33.8%); the most frequently injured anatomic sites were the lower extremities and pelvis (34.2%) and surface area of the body (17.9%). Fracture (41.5%) was the most frequent injury, followed by soft tissue injury (27.5%), but crush syndrome was relatively low (1.2%) due to the special housing structures in the Lushan area. The most commonly used procedure was suture and dressings (33.7%), followed by open reduction and internal fixation (21.9%).The results of this study help formulate recommendations to improve future disaster relief and emergency planning in remote, isolated, and rural regions of developing countries.

    Background: Many studies showed a better recovery of cognitive function after administration of exogenous lactate during moderate-severe traumatic brain injury. However, the study evaluating lactate effect on mild traumatic brain injury is still limited. Aims: To evaluate the effect of exogenous lactate on cognitive function in mild traumatic brain injury patients. Settings and Design: Prospective, single blind, randomized controlled study on 60 mild traumatic brain injury patients who were undergoing neurosurgery. Materials and Methods: Subjects were randomly assigned into hyperosmolar sodium lactate (HSL) group or hyperosmolar sodium chloride (HSS) group. Patients in each group received either intravenous infusion of HSL or NaCl 3% at 1.5 ml/KgBW within 15 min before neurosurgery. During the surgery, patients in both groups received maintenance infusion of NaCl 0.9% at 1.5 ml/KgBW/hour. Statistical Analysis: Cognitive function, as assessed by Mini-Mental State Examination (MMSE) score at 24 h, 30 and 90 days post-surgery, was analyzed by Anova repeated measures test. Results: The MMSE score improvement was significantly better in HSL group than HSS group (P < 0.001). In HSL group the MMSE score improved from 16.00 (13.75-18.00) at baseline to 21.00 (18.75-22.00); 25.00 (23.75-26.00); 28.00 (27.00-29.00) at 24 h, 30, 90 days post-surgery, respectively. In contrast, in HSS group the MMSE score almost unchanged at 24 h and only slightly increased at 30 and 90 days post-surgery. Conclusions: Hyperosmolar sodium lactate infusion during mild traumatic brain injury improved cognitive function better than sodium chloride 3%. PMID:27057222

    ABSTRACT Studies evaluating the Quality of Life of individuals with spinal cord injury using different research tools demonstrate that the Quality of Life scores are considered low both in national and international studies. The objective of this review was to characterize the international scientific production about the most used scales to assess Quality of Life in patients with spinal cord injury. We examined articles on Quality of Life of patients with spinal cord injury published over the last 5 years and indexed in the National Library of Medicine (PUBMED). During this period, 28 articles met the inclusion criteria. Eleven studies were conducted in the United States, five articles were published in Australia, and four in Canada. Brazil, France, Holland, India, Japan, Norway, Singapore and Switzerland contributed with one study each. The scientific articles were published in 13 high impact factor journals. Seven different instruments to assess Quality of Life were used in the studies: Satisfaction with Life Scale, Short Form (36) Health Survey, The Brief Version of the WHO Quality of Life Questionnaire (WHOQOL-BREF), Comprehensive Quality of Life Scale, Life Situation Questionnaire-Revised, Quality of Well-Being Scale and the SF-12® Health Survey. The articles examined underscore the impact of spinal cord injury in the Quality of Life of patients, demonstrating how this condition impairs their lives, mainly socially, but followed by the physical aspects. Despite the studies have different goals they all acknowledge that further studies are necessary in order to determine the Quality of Life of patients with spinal cord injury. Specific instruments should be chosen or developed and validated in order to fulfill this purpose PMID:25003935

    Abstract The data, concerning clinic--epidemiologic and clinic--nosological characteristic of a HIV-infected injured persons in polytrauma were adduced. There was established, that polysystemic injuries (PSI) in a HIV-infected persons occur in a younger injured patients, a trauma environment is quite a speciphic one (criminal trauma prevails), as well as mechanism of the injury occurrence (falling down is much more freqent), and the risk of a lethal outcome is determined by predominantly cranial, thoracic and abdominal components of injury. A lethal outcome occurrence risk in HIV-infected injured persons in PSI in accordance to the age signs and traumagenesis is lesser, than in a control body. It is necessary to prolong the investigations, concerning studying this phenomenon and other peculiarities of a traumatic disease in HIV-infected injured persons in polytrauma. PMID:27244924

Methods Nine patients with spinal cord injury followed in the Laboratory of Biomechanics and Rehabilitation of the Locomotive System at HC/UNICAMP were divided into two groups according to the presence of paraplegia and tetraplegia and were clinically assessed for correlation with the imaging exams. Results Normal results were found in 41% of the shoulders. Most common injuries were tendinopathy of the supraspinatus and acromioclavicular joint degeneration. Eighty percent of injured shoulders had combined lesions. Conclusion A great variety of causes of shoulder pain was identified in paraplegic and tetraplegic subjects. Routine clinical assessment and imaging studies of the shoulder may contribute to the evolution of rehabilitation and reduction of pain and musculoskeletal disorders.

    Patients with traumatic spinal cord injury (TSCI) have an increased risk of developing pressure ulcers (PU). It is a retrospective study done by review of records in order to identify the characteristics of patients who were assisted at a tertiary hospital as well as the occurrence of PU. Most patients were male, white and 36,2% between 21 and 30 years. The most common causes of TSCI were wound by fire weapons followed by vehicle crash/overturn. There was a predominance of injury at the toracic level followed by cervical. The PU occurred in 20 pacientes (42,5%). The most frequent regions of occurrence were the sacral and heels. Only 25% of the records had PU's dimensions charted, 80% stated the aspect, and 52.1% did not state the stage. There is a need for better documentation of PU so that interventions used for treatment can be evaluated. PMID:16926993

    To further explore the mechanisms underlying cortical reorganization in patients with phantom sensations after deafferentation, a repetitive transcranial magnetic stimulation study was carried out in two patients with referred phantom sensations (RPS) after incomplete spinal cord injury at the thoracic level. We delivered continuous (inhibitory), intermittent (excitatory), and placebo theta burst stimulation to the contralateral primary motor cortex (M1), primary somatosensory cortex (S1), and secondary somatosensory cortex (S2). Perception of RPS was significantly and transiently disrupted by inhibitory theta burst stimulation applied over S1 and, to a lesser extent, S2. This study supports the hypothesis that RPS depend on remapping in the somatosensory cortex and provides further electrophysiological evidence in vivo that cortical reorganizational processes are critically modulated by GABAergic mechanisms. Enhancement of GABAergic activity may block cortical reorganization, leading to RPS in spinal cord injury patients. PMID:26626415

    In this study, we aimed to determine gastrointestinal problems associated with neurogenic bowel dysfunction in spinal cord injury patients and to assess the efficacy of bowel program on gastrointestinal problems and the severity of neurogenic bowel dysfunction. Fifty-five spinal cord injury patients were included in this study. A bowel program according to the characteristics of neurogenic bowel dysfunction was performed for each patient. Before and after bowel program, gastrointestinal problems (constipation, difficult intestinal evacuation, incontinence, abdominal pain, abdominal distension, loss of appetite, hemorrhoids, rectal bleeding and gastrointestinal induced autonomic dysreflexia) and bowel evacuation methods (digital stimulation, oral medication, suppositories, abdominal massage, Valsalva maneuver and manual evacuation) were determined. Neurogenic bowel dysfunction score was used to assess the severity of neurogenic bowel dysfunction. At least one gastrointestinal problem was identified in 44 (80%) of the 55 patients before bowel program. Constipation (56%, 31/55) and incontinence (42%, 23/55) were the most common gastrointestinal problems. Digital rectal stimulation was the most common method for bowel evacuation, both before (76%, 42/55) and after (73%, 40/55) bowel program. Oral medication, enema and manual evacuation application rates were significantly decreased and constipation, difficult intestinal evacuation, abdominal distention, and abdominal pain rates were significantly reduced after bowel program. In addition, mean neurogenic bowel dysfunction score was decreased after bowel program. An effective bowel program decreases the severity of neurogenic bowel dysfunction and reduces associated gastrointestinal problems in patients with spinal cord injury. PMID:26330842

    2016-01-01

    Objective The Patient Insurance Centre in Finland reimburses patients who sustained injuries associated with medical and dental care without having to demonstrate malpractice. The aim was to analyse all dental injuries claimed through the Patient Insurance Centre over a 12-year period in order to identify factors affecting reimbursement of claims. Methods This study investigated all dental patient insurance claims in Finland during 2000-2011. The injury cases were grouped as (K00-K08) according to the International Classification of Diseases (ICD-10). Calendar year, claimant's age and gender, dental disease group and health service sector were the explanatory factors and the outcome was the decision of a claim. Multiple logistic regression modelling was used in the statistical analyses. Results The total number of decisions related to dental claims at the PIC in 2000-2011 was 7662, of which women claimed a clear majority (72%). Diseases of the pulp and periapical tissues (K04) and dental caries (K02) were the major disease groups (both 29%). Of the claims 40% were eligible for reimbursement, 27% were classified as insignificant or unavoidable injuries and 32% were rejected for other reasons. The proportion of reimbursed claims declined during the period. Patients from the private sector were more likely to be eligible for compensation than were those from the public sector (OR = 1.89, 95% CI = 1.71-2.10). Conclusions The number of dental patient insurance claims in Finland clearly rose, while the proportion of reimbursed claims declined. More claims received compensation in the private sector than in the public sector. PMID:26539839

    The objective of this study is to select one of the seven available clinical decision rules for minor head injury, for managing Iranian patients. This was a prospective cohort study evaluating medium- or high-risk minor head injury patients presenting to the Emergency Department. Patients with minor head trauma who were eligible for brain imaging based on seven available clinical decision rules (National Institute for Health and Clinical Excellence (NICE), National Emergency X-Radiography Utilization Study (NEXUS)-II, Neurotraumatology Committee of the World Federation of Neurosurgical Societies (NCWFNS), New Orleans, American College of Emergency Physicians (ACEP) Guideline, Scandinavian, and Canadian computed tomography (CT) head rule) were selected. Subjects were underwent a non-contrast axial spiral head CT scan. The outcome was defined as abnormal and normal head CT scan. Univariate analysis and stepwise linear regression were applied to show the best combination of risk factors for detecting CT scan abnormalities. Five hundred patients with minor head trauma were underwent brain CT scan. The following criteria were derived by stepwise linear regression: Glasgow Coma Scale (GCS) less than 15, confusion, signs of basal skull fracture, drug history of warfarin, vomiting more than once, loss of consciousness, focal neurologic deficit, and age over 65 years. This model has 86.15 % (75.33-93.45 %) sensitivity and 46.44 % (46.67-51.25 %) specificity in detecting minor head injury patients with CT scan abnormalities (95 % confidence interval). Of seven decision rules, only the Canadian CT Head Rule possesses seven of the eight high-risk factors associated with abnormal head CT results which were identified by this study. This study underlines the Canadian CT Head Rule's utility in Iranian minor head injury patients. Our study encourages researchers to evaluate available guidelines in different communities.

    SUMMARY Background Idiosyncratic drug-induced liver injury (DILI) is a complex disorder that is difficult to predict, diagnose and treat. Aim To describe the global serum proteome of patients with DILI and controls. Methods A label-free, mass spectrometry-based quantitative proteomic approach was used to explore protein expression in serum samples from 74 DILI patients (collected within 14 days of DILI onset) and 40 controls. A longitudinal analysis was conducted in a subset of 21 DILI patients with available 6-month follow-up serum samples. Results Comparison of DILI patients based on pattern, severity and causality assessment of liver injury revealed many differentially expressed priority 1 proteins among groups. Expression of fumarylacetoacetase was correlated with alanine aminotransferase (ALT; r = 0.237; P = 0.047), aspartate aminotransferase (AST; r = 0.389; P = 0.001) and alkaline phosphatase (r = −0.240; P = 0.043), and this was the only protein with significant differential expression when comparing patients with hepatocellular vs. cholestatic or mixed injury. In the longitudinal analysis, expression of 53 priority 1 proteins changed significantly from onset of DILI to 6-month follow-up, and nearly all proteins returned to expression levels comparable to control subjects. Ninety-two serum priority 1 proteins with significant differential expression were identified when comparing the DILI and control groups. Pattern analysis revealed proteins that are components of inflammation, immune system activation and several hepatotoxicity-specific pathways. Apolipoprotein E expression had the greatest power to differentiate DILI patients from controls (89% correct classification; AUROC = 0.97). Conclusion This proteomic analysis identified differentially expressed proteins that are components of pathways previously implicated in the pathogenesis of idiosyncratic drug-induced liver injury.

    Rationale. By reducing cerebral oxygen delivery, anemia may aggravate traumatic brain injury (TBI) secondary insult. This study evaluated the impact of anemia and blood transfusion on TBI outcomes. Methods. This was a retrospective cohort study of adult patients with isolated TBI at a tertiary-care intensive care unit from 1/1/2000 to 31/12/2011. Daily hemoglobin level and packed red blood cell (PRBC) transfusion were recorded. Patients with hemoglobin < 10 g/dL during ICU stay (anemic group) were compared with other patients. Results. Anemia was present on admission in two (2%) patients and developed in 48% during the first week with hemoglobin < 7 g/dL occurring in 3.0%. Anemic patients had higher admission Injury Severity Score and underwent more craniotomy (50% versus 13%, p < 0.001). Forty percent of them received PRBC transfusion (2.8 ± 1.5 units per patient, median pretransfusion hemoglobin = 8.8 g/dL). Higher hospital mortality was associated with anemia (25% versus 6% for nonanemic patients, p = 0.01) and PRBC transfusion (38% versus 9% for nontransfused patients, p = 0.003). On multivariate analysis, only PRBC transfusion independently predicted hospital mortality (odds ratio: 6.8; 95% confidence interval: 1.1–42.3). Conclusions. Anemia occurred frequently after isolated TBI, but only PRBC transfusion independently predicted mortality. PMID:26605080

    Background: Incidental findings on computed tomography (CT) scans are occasionally noted in patients presenting with head injury. Since it can be assumed that head injured patients are of normal health status before the accident, these findings may be a representation of their frequency in the general population. Our aim was to determine the prevalence of such incidental findings among head injured patients in Nigeria's foremost center of clinical neurosciences. Materials and Methods: We conducted a retrospective review of CT scan images of 591 consecutive eligible patients over a 5-year period (2006-2010) to identify incidental findings. The images were evaluated by consensus agreement of two radiologists. Associations with gender and age were explored using appropriate statistical tests with an alpha level of 0.05. Results: The mean patient age was 34.6 ± 21.2 years, and male to female ratio was 3.2: 1. Incidental findings were noted in 503/591 (85.1 %) of the scans. Intracranial calcification was the commonest finding occurring in 61.8% of patients. Over 90% of the findings were benign. Compared with older ones, patients under the age of 60 were less likely, (P < 0.001), to have incidental findings. Conclusion: Although the majority of incidental findings in this African cohort of head injury patients are benign some clinically significant lesions were detectable. It is therefore recommended that such findings be adequately described in the radiological reports for proper counseling and follow-up. PMID:25949036

    Structure Summary Objective Although not previously reported, experience suggests that dentoalveolar injury (DAI) is common among patients with maxillofacial (MF) fractures. The objective of this study was to evaluate and describe the prevalence and nature of DAIs in patients identified with MF fractures. Methods Medical records of 43 dogs and cats diagnosed with MF fractures between 2005–2012 were reviewed to identify patients with concurrent DAI. Medical records of patients with DAI were abstracted for the following information: signalment (including sex, age, and skull type), mechanism of MF trauma, location and number of MF fractures, DAI type and location and the number of DAI per patient. Statistical evaluation was performed to determine associations between signalment; mechanism of trauma; location and number of MF fractures; and the prevalence and nature of concurrent DAI. Results Dentoalveolar injuries are common among patients with MF trauma. Age and mechanism of trauma are significant predictors of the presence of DAI in patients with MF trauma. Conclusions and Clinical Relevance The findings of this study serve to encourage veterinarians to fully assess the oral cavity in patients with MF fractures as DAI are common and can be predicted by age and mechanism of trauma.

    Background: Malignant peripheral nerve sheath tumors (MPNSTs) of the brachial plexus have unique radiographic and clinical findings. Patients often present with progressive upper extremity paresthesias, weakness, and pain. On magnetic resonance (MR) imaging, lesions are isointense on T1-weighted and hyperintense on T2-weighted sequences, while also demonstrating marked enhancement on MR studies with gadolinium diethylenetriamine pentaacetic acid. On the basis of their characteristic MR imaging features and rapid clinical progression, two brachial plexus lesions proved to be organizing hematomas rather than MPNST. Methods: A 51-year-old male and a 31-year-old female were both assessed for persistent and worsened left-sided upper extremity pain, paresthesias, and weakness. In both cases, the MR imaging of the brachial plexus demonstrated an extraspinal enhancing lesion located within the left C7–T1 neuroforamina. Results: Although the clinical and radiographic MR features for these 2 patients were consistent with MPNSTs, both lesions proved to be benign organizing hematomas. Conclusions: These two case studies emphasize that brachial plexus hematomas may mimic MPNSTs on MR studies. Accurate diagnosis of these lesions is critical for determining the appropriate management options and treatment plans. Delaying the treatment of a highly aggressive nerve sheath tumor can have devastating consequences, whereas many hematomas resolve without surgery. Therefore, if the patient has stable findings on neurological examination and a history of trauma, surgical intervention may be delayed in favor of repeat MR imaging in 2–3 months to re-evaluate the size of the mass.

    We describe the clinical impact of the RehaCom computerized cognitive training program instituted in the International Neurological Restoration Center for rehabilitation of brain injury patients. Fifty patients admitted from 2008 through 2010 were trained over 60 sessions. Attention and memory functions were assessed with a pre- and post-treatment design, using the Mini-Mental State Examination, Wechsler Memory Scale and Trail Making Test (Parts A and B). Negative effects were assessed, including mental fatigue, headache and eye irritation. The program's clinical usefulness was confirmed, with 100% of patients showing improved performance in trained functions. PMID:23154316

    The Initial Systolic Time Interval (ISTI), obtained from the electrocardiogram and impedance cardiogram, is considered to be a measure for the time delay between the electrical and mechanical activity of the heart. This time delay is influenced by the sympathetic nerve system. Therefore, an observational study was performed in a group of patients (SCI) with spinal cord injuries. The relationship between the ISTI and the total heart cycle (RR-interval) was established by varying the RR-interval using an exercise stimulus to increase the heart rate. The slope of this relationship was observed to be significantly higher in the SCI-group as compared with a control group, although there was no difference in ISTI in the range of common heart rates during the test between the groups. This slope and the ISTI was observed to be significantly different in an acute patient having a recent spinal cord injury at a high level. Because of the variety in injury levels and incompleteness of the injuries further, more specific research is necessary to draw decisive conclusions with respect to the contribution of autonomic nervous control on the ISTI in SCI, although the present observations are notable.

  9. The influence of immediate physiotherapy in the out-patient management of acute knee injuries: a controlled study.

    All patients who presented to our Accident & Emergency Department over a 6-month period with an acute knee injury were randomly assigned to receive either immediate physiotherapy or not prior to further follow up at an out-patient clinic. Patients with trivial injuries not requiring follow up and patients with severe injuries requiring immediate admission were excluded from the study. Patients not immediately referred for physiotherapy could be referred if this was thought necessary at later follow up. There was no statistical difference in the number of outpatient follow up appointments or the length of time to discharge from the clinic between the groups. Those patients referred for physiotherapy immediately had a significantly greater number of total attendances at the physiotherapy department. However more patients in the 'no physiotherapy' group ultimately required arthroscopy for suspected meniscal injury. We conclude that a blanket referral of all acute knee injury patients is unjustified and wasteful of resources. However physiotherapy may be indicated in patients initially suspected of having meniscal injury. PMID:2099163

    Laryngomalacia occurs in some brain injury patients secondary to global muscle hypotonia. Surgical therapies for epiglottis prolapse have centered around removal or reshaping of the epiglottis. This approach has brought mixed success and frequent complications. We present a case that demonstrates successful nonsurgical treatment of a 33-year-old male brain injury patient with moderate obstructive sleep apnea that is believed to be a consequence of post-brain injury nocturnal epiglottis prolapse. The presence of a tracheostomy performed at the time of emergency surgery had become an emotional and physical barrier to our patient's recovery. The tracheostomy could only be reversed if the obstructive sleep apnea disorder could be managed in an alternative fashion. A titratable mandibular repositioning appliance was prescribed and its effectiveness was demonstrated with nasolaryngoscopy and polysomnography. After initially fitting the oral appliance, a period of accommodation and gradual protrusive adjustments was allowed. Subsequent confirmation polysomnography demonstrated improvement, but not suitable resolution, of disordered breathing events. However, an additional 1.25-mm protrusive titration of the oral appliance during the course of the confirmation polysomnogram led to therapeutic success. The patient's tracheostomy was subsequently reversed with significant quality of life benefits. PMID:15389392

    Patient: Male, 66 Final Diagnosis: Awakening blood pressure rise Symptoms: Syncope Medication: — Clinical Procedure: Ambulatory blood pressure monitoring Specialty: Cardiology Objective: Challenging differential diagnosis Background: The pathophysiological mechanism causing awakening blood pressure (BP) rise is not clear. Case Report: We report the case of a 66-year-old man with a history of spinal cord injury, and who had remarkable awakening BP rise in ambulatory BP monitoring. The patient also had orthostatic hypotension and post-prandial hypotension associated with an increased insulin level. This case suggests that awakening BP rise can occur without increased physical activity or positional changes, in those with autonomic nerve dysreflexia associated with a spinal cord injury. The reduction of elevated awakening BP level can be affected by eating breakfast in association with an increased insulin level. However, in ambulatory BP monitoring, the awakening BP rise was reproducible, but this patient also exhibited evening BP rise in home BP monitoring when he took a nap. Conclusions: Exaggerated awakening BP rise can occur in patients with spinal cord injury without positional change, and the recovery of BP may be modified by post-prandial and orthostatic BP drop.

    Abstract We reported on the ascending reticular activating system (ARAS) finding of a patient in whom severe injury of the cerebral cortex was detected following a hypoxic-ischemic brain injury (HIBI). A 67-year-old female patient who suffered from HIBI induced by cardiac arrest after surgery for lumbar disc herniation underwent cardiopulmonary resuscitation approximately 20 to 30 minutes after cardiac arrest. The patient exhibited impaired alertness, with a Glasgow Coma Scale (GCS) score of 4 (eye opening: 2, best verbal response: 1, and best motor response: 1). Approximately 3 years after onset, she began to whimper sometimes and showed improved consciousness, with a GCS score of 10 (eye opening: 4, best verbal response: 2, and best motor response: 4) and Coma Recovery Scale-Revised score of 9 (auditory function: 1, visual function: 1, motor function: 2, verbal function: 2, communication: 1, and arousal: 2). Results of diffusion tensor tractography for the upper connectivity of the ARAS showed decreased neural connectivity to each cerebral cortex in both hemispheres. The right lower ARAS between the pontine reticular formation and the thalamic intralaminar nuclei (ILN) was thinner compared with the left side. Severe injury of the upper portion of the ARAS between the thalamic ILN and cerebral cortex was demonstrated in a patient with some level of consciousness. PMID:26496328

    Traumatic Brain Injury (TBI) has been considered as a serious public health problem. Each year, traumatic brain injuries are contributing to a substantial number of cases of permanent disability and deaths and it can be classified according to the severity into penetrating and closed head injury. Symptoms, beside to be unconscious can be defined as vomiting, nausea, headache, dizziness, lack of motor coordination, difficulty in balancing, blurred vision and lightheadedness, bad taste in the mouth, ringing in the ears, fatigue and lethargy as well as changes in sleep patterns. The brain is known to be the functional regulator for all the metabolic activities inside the body and TBI patients mostly have a complex metabolic alterations including aberrant cellular metabolism, abnormal metabolic processes, changes in hormones functions and inflammatory cascade. The TBI patient's status needed to be assessed medically and nutritionally since the medical status of the patients can affect the nutrition part. Data from the four assessment tools are needed to be correctly used and interpreted in order to make a proper nutritional diagnosis, clinical assessment, biochemistry as well as anthropometric measurements. Regardless the methods used for assessing TBI patients, having adequate intake and medical care can lead to a reduction in hospital costs, numbers of day hospitalized, numbers of hours of mechanical ventilation and in the overall infection rates.

    We report a previously undescribed inflammatory lesion consisting of deposition of activated complement (C3d and C9neo) in association with major histocompatibility complex type II (MHC2)-positive activated microglia in choroid plexus villi exhibiting classical fibrous thickening of the pericapillary filtration membrane. The proportion of villi affected ranged from 5% to 90% in 56 adult subjects with diseases of the CNS and 11 subjects with no preexisting disease of the CNS. In 3 of the 4 children studied, 2% or less of examined villi showed stromal thickening, complement deposition, and the presence of MHC2-positive microglia; in adults, the proportion of villi affected increased with age. Other features of the lesion included loss of capillaries and failure by macrophages to clear extracellular particulate electron-dense material by clathrin-mediated phagocytosis. This choroid plexus lesion may relate pathogenetically to age-related macular degeneration and to Alzheimer disease, 2 other conditions with no known risk factors other than increasing age. All 3 conditions are characterized by the presence of damaged capillaries, inflammatory extracellular aggregates of mixed molecular composition and defective clearance of the deposits by macrophages.

    Ten children, aged 4 to 14 years, sustaining blunt arterial trauma from motor vehicle collisions (6), bicycle accidents (2), and falls (2) were identified over a 10-year period. The arteries injured included the common iliac (3), abdominal aorta (2), carotid (2), brachial (2), and the subclavian, renal, and femoral artery (1 each). One patient had three arterial injuries. Six patients had associated injuries including a pelvic and lumbar spine fracture, Horner's syndrome, liver laceration, skull fracture, open humerus fracture, small bowel serosal tear, and a brachial plexus injury. Definitive diagnosis was made using arteriography (6), computed tomography (CT) scan (2), and physical examination (2). The types of arterial injuries found included incomplete transection, complete transection with pseudo-aneurysm formation, traumatic arteriovenous (AV) fistulas, complete occlusion, and dissection. Repair was accomplished by hypogastric artery interposition or bypass grafting, synthetic grafting with polytetrafluoroethylene (PTFE), reverse saphenous vein grafting, or primary repair, depending on the circumstances. An AV fistula between the carotid artery and cavernous sinus was embolized. All grafts remained patent with exception of the aorto-renal bypass graft at follow-up ranging from 1 month to 3 years. The principles for repairing vascular injuries in children are slightly different than those in adults. Every effort should be made to use autogenous tissue such as the hypogastric artery or saphenous vein for repair if possible. If not, PTFE grafts can be used, although the long-term patency of these grafts in growing children is not known. PMID:15156954

    A total of 75 patients with penetrating cardiac injuries were treated at Lincoln Medical and Mental Health Center from January, 1974, to November, 1980. Twenty-two patients (29.3%) were unconscious on arrival and had no detectable vital signs, cardiac activity, or spontaneous respirations. Their last physical movement was observed in the ambulance. Immediate resuscitation of these patients employing intercostal or sternal splitting incisions in the emergency room revealed arrested hearts and permitted relief of tamponade, finger occlusion of the cardiac wound or wounds, and temporary suturing of the defect. Restoration of cardiac function was accomplished in 16 patients (72.7%). After transfer to the operating room for more definitive cardiorrhaphy and repair of other major wounds, 8 patients (36.4%) recovered without objective neurological disability. Our experience clearly supports the value of immediate emergency room thoracotomy in this group of patients. PMID:7305523

    A number of tendon transfers have been described for opponensplasty. Transfer of the palmaris longus (PL) tendon with a palmar fascial extension was initially described by Camitz. This technique has mostly been combined with carpal tunnel release in patients with long standing median neuropathy with atrophy of the thenar muscles. However, the Camitz transfer has not been previously described in the setting of pediatric median nerve injury. We report 4 cases of Camitz transfer in pediatric patients with median nerve injuries. Four children (all female; age range 3-15 yrs) underwent PL tendon transfer following median nerve injury. The causes of injury included trauma, iatrogenic injury, and neuritis of the brachial plexus. The Camitz procedure was performed at the time of median nerve decompression and/or reconstruction. All patients had excellent early return of function. Transfer of the palmaris longus tendon reliably restores palmar abduction, with minimal to no additional morbidity, in carefully selected pediatric patients with median nerve injury undergoing release of the carpal tunnel.

    Pancreatic cancer is the second most common abdominal cancer in North America with an estimated 20% resectability at diagnosis, and overall 5-year survival of 5%. Pain is common in pancreatic cancer patients with 70%-80% suffering substantial pain. Celiac plexus neurolysis (CPN) is a technique that can potentially improve pain control in pancreatic cancer while preventing further escalation of opioid consumption. CPN is performed by injecting absolute alcohol into the celiac plexus neural network of ganglia. This review sets out to explore the current status of CPN in non-resectable pancreatic cancer. We will examine: (1) the efficacy and safety of percutaneous-CPN and endoscopic ultrasound guided-CPN; (2) specific technique modifications including bilateral (vs central) injections and celiac ganglia neurolysis; and (3) the issue of CPN timing, early at pancreatic cancer diagnosis vs traditional late use as salvage therapy.

    Forty-six patients with spinal injury with dysfunctional neurogenic bladder were analyzed. Fourteen patients on prolonged intermittent catheterization from 12 weeks to more than 1 year did not develop a balanced bladder, 14 patients had indwelling catheters after intermittent catheterization failed elsewhere and 18 patients on external condom drainage presented with difficult voiding and repeated infections. There were 16 quadriplegics (1 incomplete), 21 paraplegics, and 9 incomplete cauda equina lesions. Urologic and urodynamic evaluation revealed detrusor-sphincter dyssynergia in 15 patients, vesicoureteral reflux in 10, and areflexic bladders in 11. Five patients over the age of 55 years showed slight enlargement of the prostrate. Some degree of bladder neck fibrosis was suspected in 26. More than one urologic pathology was encountered in the same patient. Transurethral sphincterotomy was carried out in 38 patients and only one transurethral resection of the prostrate (TURP) in an incomplete quadriplegic patient. In seven patients with no obvious urodynamic abnormality, a balanced bladder was achieved with intermittent catheterization; however, one of these patients needed a transurethral sphincterotomy on subsequent admission. A balanced bladder was achieved in all patients except the one with incomplete quadriplegia. Significant improvement in vesicoureteral reflux and relief from autonomic dysreflexic symptoms were recorded in all patients. PMID:619856

    Vibratory perception thresholds were measured by an electromagnetic device applied over the clavicles of 64 patients with spinal cord injuries. Patients with neurological levels of C5 and below had low threshold values (0.63 +/- 0.23 micron of vibration amplitude; mean +/- SD) which were used as reference values. The patients with a neurological level of C1/2 had very high vibratory thresholds bilaterally (above 11.0 micron). Patients with C2/3-3/4 neurological levels also had significantly elevated thresholds (2.56 +/- 2.01 micron), while those with C4-C4/5 levels did not differ significantly from the reference group. The results agree with earlier observations that the C4 segment innervates the clavicle and imply that patients with a lesion at or above C4 may have elevated clavicular vibratory thresholds. It is concluded that vibrametry, a non-invasive technique, is applicable in patients with spinal cord injury and disease, and can be useful for assessment of sensory level and particularly for follow-up of such patients.

    Abstract We examined clofarabine pharmacokinetics and association with renal toxicity in 62 patients participating in a phase I-II study of clofarabine-melphalan-alemtuzumab conditioning for hematopoietic stem cell transplant (HSCT). Pharmacokinetic parameters, including clofarabine area under the concentration-time curve (AUC), maximum concentration and clearance, were measured, and patients were monitored for renal injury. All patients had normal pretreatment creatinine values, but over half (55%) experienced acute kidney injury (AKI) after clofarabine administration. Age was the strongest predictor of AKI, with older patients at greater risk (p = 0.002). Clofarabine AUC was higher in patients who developed AKI, and patients with the highest dose-normalized AUCs experienced the most severe grades of AKI (p = 0.01). Lower baseline renal function, even when normal, was associated with lower clofarabine clearance (p = 0.008). These data suggest that renal-adjustment of clofarabine dosing should be considered for older and at-risk patients even when renal function is ostensibly normal. PMID:24564572

  2. Developmental changes in the transcriptome of the rat choroid plexus in relation to neuroprotection

    PubMed Central

    2013-01-01

    Background The choroid plexuses are the interface between the blood and the cerebrospinal fluid (CSF) contained within the ventricular spaces of the central nervous system. The tight junctions linking adjacent cells of the choroidal epithelium create a physical barrier to paracellular movement of molecules. Multispecific efflux transporters as well as drug-metabolizing and antioxidant enzymes functioning in these cells contribute to a metabolic barrier. These barrier properties reflect a neuroprotective function of the choroid plexus. The choroid plexuses develop early during embryogenesis and provide pivotal control of the internal environment throughout development when the brain is especially vulnerable to toxic insults. Perinatal injuries like hypoxia and trauma, and exposure to drugs or toxic xenobiotics can have serious consequences on neurogenesis and long-term development. The present study describes the developmental expression pattern of genes involved in the neuroprotective functions of the blood–CSF barrier. Methods The transcriptome of rat lateral ventricular choroid plexuses isolated from fifteen-day-old embryos, nineteen-day old fetuses, two-day old pups, and adults was analyzed by a combination of Affymetrix microarrays, Illumina RNA-Sequencing, and quantitative RT-PCR. Results Genes coding for proteins involved in junction formation are expressed early during development. Overall perinatal expression levels of genes involved in drug metabolism and antioxidant mechanisms are similar to, or higher than levels measured in adults. A similar developmental pattern was observed for multispecific efflux transporter genes of the Abc and Slc superfamilies. Expression of all these genes was more variable in choroid plexus from fifteen-day-old embryos. A large panel of transcription factors involved in the xenobiotic- or cell stress-mediated induction of detoxifying enzymes and transporters is also expressed throughout development.

    [Purpose] The purpose of this study was to determine the effects of aquatic exercise on pulmonary function of patients with spinal cord injury. [Subjects] The subjects were randomly allocated to an aqua group (n=10) and a land group (n=10). [Methods] Both groups trained for 60 minutes, 3 times a week for 8 weeks. Pulmonary function was assessed by measuring the forced vital capacity (FVC), forced expiratory flow rate (FER), force expiratory volume at one second (FEV1) and force expiratory volume at one second/forced vital capacity (FEV1/FVC). [Results] Following the intervention, the aqua group showed significant changes in FVC, FER, FEV1, and FEV1/FVC. The land group showed only significant differences FER. [Conclusion] The results of this study suggest the effects on the aqua group were significantly higher than those on the land group in patients with spinal cord injury. PMID:24926136

    A 19-year-old woman presented with pelvic trauma following a road accident. She was hemodynamically stable. Examination revealed perineal injuries and type C pelvic fracture, which was stabilized with an external fixator. The broken ends of the pubic bone were brought together by an orthopedic wire. The detached vaginal wall and torn anal sphincter were surgically repaired after making a diverting colostomy. The postoperative period was uneventful. Colostomy was reversed after 3 months. Postoperatively the patient developed a cystocele, dyspareunia and vaginal pain. She conceived spontaneously and was planned for an elective cesarean at 37 weeks gestation; however, she presented in labor at 36 weeks and had a normal vaginal delivery. Pelvic fractures may be associated with genitourinary and anal sphincter injuries, which require management by a multidisciplinary team. On recovery the patient may develop prolapse, dyspareunia and persistent local pain. Spontaneous conception and normal vaginal delivery are nevertheless possible. PMID:22540310

    Severe amotivation, apathy, and abulia, significantly retard rehabilitation following traumatic brain injury. Preliminary, uncontrolled research has suggested possible benefit with amantadine for this behavioural syndrome. This N of 1, double-blind, placebo-controlled study employed amantadine 100 mg three times daily in one such patient. Therapists and nurses completed inventories scoring efforts towards initiation of therapeutic activities during each session, progress in therapy, and participation in therapy. Four treatment periods (two active medication, two placebo), of 2 weeks duration, were completed. Across four therapists, and for both treatment pairs, the average effect score increased from 0.86 on placebo to 1.74 on amantadine (possible range 0-6, 3 = 'average'). There were no side-effects. The study suggests possible benefit with amantadine for patients with amotivational syndrome after traumatic brain injury; a randomized clinical trial appears warranted and required. PMID:7874096

  6. Brachial plexus birth palsy: Management during the first year of life.

    Brachial plexus birth palsy (BPBP) is defined as an injury to any nerve root of the brachial plexus during difficult delivery. BPBP is relatively rare; its incidence has remained constant over the last few decades, mostly due to unpredictable risk factors, such as shoulder dystocia. Both diagnosis and assessment of spontaneous recovery is based on clinical examination. Electromyography is difficult to interpret in the newborn and is therefore not meaningful. MRI of the cervical spine requires sedation or general anesthesia. Searching for a pre-ganglion tear prior to surgery is indicted. Prognosis depends on the level of the injury (pre- or post-ganglion), size and severity of the post-ganglion tears, speed of recovery, and quality of initial management. Although spontaneous recovery is frequent, some children suffer various degrees of sequelae, up to complete loss of function of the affected upper limb. Recent publications have improved general knowledge and indications for surgery. However, some aspects, such as indication and timing of nerve repair continue to be debated. PMID:26774906

    It is known that in severe acquired brain injuries there is process of neuroinflammation, with the activation of a local and general stress response. In our study we considered six patients with disorders of consciousness (five in vegetative state and one in minimal consciousness state) in subacute phase, which had both a clinical assessment and a functional imaging (fMRI): in all these patients we analised blood levels of osteopontin (OPN), a cytokin involved in neuroinflammation but also in neurorepair with a still discussed role. Besides we studied the lymphocyte subsets and blood levels of some hormones (ADH, ACTH, PRL, GH, TSH, fT3, fT4). We found a positive correlation between the levels of serum osteopontin (higher than normal in all subjects) and the severity of the brain injury, especially for prognosis: actually, the patient with the lowest level has emerged from minimal consciousness state, while the one with the highest level has died a few days after the evaluation. The lymphocyte subset was altered, with a general increase of CD4+/CD3+ ratio, but without a so strict correlation with clinical severity; the only hormone with a significant increase in the worse patients was prolactin. In fMRI we detected some responses to visual and acoustic stimuli also in vegetative states, which had no clinical response to this kind of stimulation but generally have had a better prognosis. So we conclude that osteopontin could be a good marker of neuroinflammation and relate to a worse prognosis of brain injuries; the lymphocyte alterations in these disorders are not clear, but we suspect an unbalance of CD4 towards Th2; PRL is the best endocrinological marker of brain injury severity; fMRI surely plays an important role in the detection of subclinical responses and in prognostic stratification, that is still to define with more studies and statistical analysis.

    The objective of this study was to identify the optimal frequency range for computing the pressure reactivity index (PRx). PRx is a clinical method for assessing cerebral pressure autoregulation based on the correlation of spontaneous variations of arterial blood pressure (ABP) and intracranial pressure (ICP). Our hypothesis was that optimizing the methodology for computing PRx in this way could produce a more stable, reliable and clinically useful index of autoregulation status. The patients studied were a series of 131 traumatic brain injury patients. Pressure reactivity indices were computed in various frequency bands during the first 4 days following injury using bandpass filtering of the input ABP and ICP signals. Patient outcome was assessed using the extended Glasgow Outcome Scale (GOSe). The optimization criterion was the strength of the correlation with GOSe of the mean index value over the first 4 days following injury. Stability of the indices was measured as the mean absolute deviation of the minute by minute index value from 30-min moving averages. The optimal index frequency range for prediction of outcome was identified as 0.018-0.067 Hz (oscillations with periods from 55 to 15 s). The index based on this frequency range correlated with GOSe with ρ=-0.46 compared to -0.41 for standard PRx, and reduced the 30-min variation by 23%. PMID:24664812

    The usability concept refers to aspects related to the use of products that are closely linked to the user's degree of satisfaction. Our goal is to present a functional evaluation methodology for assessing the usability of sophisticated technical aids, such as a portable robot for helping disabled patients with severe spinal cord injuries. The specific manipulator used for this task is ASIBOT, a personal assistance robot totally developed by RoboticsLab at the University Carlos III of Madrid. Our purpose is also to improve some aspects of the manipulator according to the user's perception. For our case study, a population of six patients with spinal cord injury is considered. These patients have been suffering spinal cord injuries for a period of time longer than 1 year before the tests are carried out. The methodology followed for the information gathering is based on the Quebec User Evaluation of Satisfaction with assistive Technology (QUEST). Different daily functions, such as drinking, brushing one's teeth and washing one's face, are considered to assess the user's perception when using ASIBOT as a technical aid. The human factor in this procedure is the main base to establish the specific needs and tools to make the end product more suitable and usable. PMID:20969432

    OBJECTIVE Neonatal brachial plexus palsy (NBPP) occurs due to the stretching of the nerves of the brachial plexus before, during, or after delivery. NBPP can resolve spontaneously or become persistent. To determine if nerve surgery is indicated, predicting recovery is necessary but difficult. Historical attempts explored the association of recovery with only clinical and electrodiagnostic examinations. However, no data exist regarding the neonatal and peripartum factors associated with NBPP persistence. METHODS This retrospective cohort study involved all NBPP patients at the University of Michigan between 2005 and 2015. Peripartum and neonatal factors were assessed for their association with persistent NBPP at 1 year, as defined as the presence of musculoskeletal contractures or an active range of motion that deviated from normal by > 10° (shoulder, elbow, hand, and finger ranges of motion were recorded). Standard statistical methods were used. RESULTS Of 382 children with NBPP, 85% had persistent NBPP at 1 year. A wide range of neonatal and peripartum factors was explored. We found that cephalic presentation, induction or augmentation of labor, birth weight > 9 lbs, and the presence of Horner syndrome all significantly increased the odds of persistence at 1 year, while cesarean delivery and Narakas Grade I to II injury significantly reduced the odds of persistence. CONCLUSIONS Peripartum/neonatal factors were identified that significantly altered the odds of having persistent NBPP at 1 year. Combining these peripartum/neonatal factors with previously published clinical examination findings associated with persistence should allow the development of a prediction algorithm. The implementation of this algorithm may allow the earlier recognition of those cases likely to persist and thus enable earlier intervention, which may improve surgical outcomes. PMID:26799409

    This study investigates early maladaptive schemas (EMSs) in function of eating disorder (ED) subtypes (restrictive/bulimic) and the presence/absence of non-suicidal self-injury (NSSI). Female inpatients (N = 491) completed the Young Schema Questionnaire and the Self-Injury Questionnaire. The influence of ED subtype and the presence/absence of NSSI and their interaction on the EMS were investigated by means of a MANCOVA. The results showed main effects of ED subtype and the presence of NSSI on EMS. Patients with bulimia scored significantly higher on insufficient self-control and emotional deprivation, which are more related to cluster B compared with restrictive patients, whereas restrictive patients scored significantly higher on social undesirability, failure to achieve, subjugation and unrelenting standards compared with patients with bulimia that are more related to cluster C. Patients with ED with NSSI reported significantly higher EMS levels compared with patients without NSSI, suggesting that they could be of particular interest to benefit from schema therapy.

    The objectives are to identify the main injury patterns in the various types of user (of cars, motorcycles/mopeds, bicycles and pedestrians) injured in traffic crashes and treated in hospital emergency services, along with their main demographic characteristics. One-year cumulative survey all of patients attended to emergency departments in Barcelona, Spain, over a 12-month period (1998) for injuries due to motor vehicle crashes. Bivariate descriptive analyses were conducted to identify the different profiles of motor-vehicle injury patients by age, sex, user type, injured body region and type of injuries. ISS scoring was used to determine injury severity. Of the nearly 17,000 injured traffic victims during 1998, 62% were men. Young people between 15 and 39 (71.6%) were most affected. 42% were users of two-wheeled motor vehicles, followed by car occupants (32%) and pedestrians (24%). Neck sprain (33%) was the most common injury among car occupants, multiple contusion and contusion of lower limbs among two-wheeled motor vehicles (23.5% and 14% respectively) and pedestrians (17.3% and 14.4% respectively) and upper limb fractures (20%) among cyclists. Motorcycle and moped users, mainly young males, have the highest probability of suffering injuries, with lower limbs being the most affected anatomical region. Elderly pedestrians sustaining injuries to the lower limbs and the head contribute substantially to the overall injury situation. PMID:11558100

    Psammoma bodies are structures classified in the group of dystrophic calcifications, which occur in some kind of tumors and in choroid plexus during the aging process. Despite early discovery of their presence in choroid plexus stroma, mechanisms responsible for their formation remained unclear. Their presence in some kind of tumors was even more extensively studied, but significant breakthrough in the field of their etiology was not attained, too. However, till today correlation between their presence in tumors and aging is not established. Also, there are not any data about structural differences between ones found in tumors and ones found in choroid plexus. This might points to the assumption that besides the aging, some other causes might be involved in their formation in choroid plexus. Furthermore, it is contradictory that forms, like psammoma bodies, present in such malignant formations as tumors, represent quite benign phenomenon in choroid plexus. Literature data and the results of our previous researches revealed that there might be connections between, these, on the first sight quite different processes. Firstly, psammoma bodies are present in stroma of tumors with predominantly papillomatous morphology, which is present in choroid plexus, too. Initial forms of psammoma bodies might be formed in fibrovascular core of choroid plexus villi, similarly like in tumors papillae of papillary thyroid cancer. Their further growth leads to the progressive destruction of both tumors papillae and choroidal villi. Choroid plexus stroma is characterized by the fenestrated blood vessels presence, which are similar to newly formed vessels in tumors. This makes it vulnerable to the noxious agents from circulation. It can contain lymphocytes, macrophages, dendritic cells and myofibroblasts in cases with psammoma bodies, similarly to tumors stroma which is in activated, proinflammatory state. So, all these facts can suggest that similar processes can lead to psammoma

    Assisted semen retrieval was applied in 219 men with spinal cord injury (212 supranuclear, seven infranuclear lesions). Vibrostimulation in supranuclear lesions was successful in 133, and in five more after physostigmine injection. Electroejaculation was successful in all seven infranuclear lesions and in four supranuclear patients failing with vibrostimulation. Eight more supranuclear patients responded to electroejaculation and physostigmine. Surgical retrieval was applied in 27 patients. Nine Wagenknecht spermatoceles showed only one success, from all 18 implanted Brindley reservoirs semen could be collected. Three patients, in whom no pregnancy could be induced after Brindley reservoir implantation, had testicular sperm aspirated. In 109 patients who wanted to have offspring, 73 pregnancies could be induced in 46 couples, leading to 54 births (four twins), 16 abortions and three pregnancies. Conservative semen retrieval was possible in 82 of these men (63 pregnancies in 37 couples) and surgical methods were used in 27 (10 pregnancies in nine couples). PMID:9232752

    The aim of this stuty is to describe a case of endophthalmitis after tooth extraction in a patient with previous perforating eye injury. 50 years old male patient attempted to our clinic with complaints of sudden severe pain, reduced vision, light sensitivity and redness in the right eye. The patient stated that severe pain in his eye began approximately 12 hours following tooth extraction. The patient's ocular examination revealed a visual acuity of hand motion in the right eye. Anterior segment examination of the right eye showed intense conjunctival hyperemia, chemosis, a fine keraticprespitat and corneal edema. Dental procedures of the patients who had recently underwent ocular surgery or trauma should be done in a more controlled manner under anti -infective therapy or should be postponed in elective procedures.

    Introduction. The relationship between cervical spine injury (CSI) and helmet in head injury (HI) patients following motorcycle crashes is crucial. Controversy still exists; therefore we evaluated the effect of various types of helmets on CSI in HI patients following motorcycle crashes and researched the mechanism of this effect. Patients and Methods. A total of 5225 patients of motorcycle crashes between 2000 and 2009 were extracted from the Head Injury Registry in Taiwan. These patients were divided into case and control groups according to the presence of concomitant CSI. Helmet use and types were separately compared between the two groups and the odds ratio of CSI was obtained by using multiple logistic regression analysis. Results. We observed that 173 (3.3%) of the HI patients were associated with CSI. The HI patients using a helmet (odds ratio (OR) = 0.31, 95% confidence interval (CI) = 0.19−0.49), full-coverage helmet (0.19, 0.10−0.36), and partial-coverage helmet (0.35, 0.21−0.56) exhibited a significantly decreased rate of CSI compared with those without a helmet. Conclusion. Wearing full-coverage and partial-coverage helmets significantly reduced the risk of CSI among HI patients following motorcycle crashes. This effect may be due to the smooth surface and hard padding materials of helmet. PMID:25705663

    Introduction. Management of haemodynamically stable patients with penetrating abdominal injuries varies from nonoperative to operative management. The aim was to investigate whether peritoneal breach when used as an indication for exploratory laparotomy appropriately identified patients with intra-abdominal visceral injury. Methods. We conducted retrospective cohort study of all patients presenting with PAI at a major trauma centre from January 2007 to December 2011. We measured the incidence of peritoneal breach and correlated this with intra-abdominal visceral injury diagnosed at surgery. Results. 252 patients were identified with PAI. Of the included patients, 71 were managed nonoperatively and 118 operatively. The operative diagnoses included nonperitoneal-breaching injuries, intraperitoneal penetration without organ damage, or intraperitoneal injury with organ damage. The presenting trauma CT scan was reported as normal in 63%, 34%, and 2% of these groups, respectively. The total negative laparotomy/laparoscopy rate for all patients presented with PAI was 21%, almost half of whom had a normal CT scan. Conclusion. We found that peritoneal breach on its own does not necessarily always equate to intra-abdominal visceral injury. Observation with sequential examination for PAI patients with a normal CT scan may be more important than exclusion of peritoneal breach via laparoscopy. PMID:26064688

    Mild traumatic brain injury (mTBI) is often occult to conventional imaging techniques. However, there is growing evidence that mTBI patients who lack evidence of structural intracranial injury may develop post-concussive syndrome (PCS). We investigated longitudinal alterations in resting state functional connectivity (rs-FC) in brain networks in a population of 28 patients compared to 28 matched control participants. Rs-FC and cerebral blood flow (CBF) within the nodes of the Default Mode Network (DMN) and Task Positive Network (TPN) were assessed at three time points including acute, sub-acute, and chronic stages following mTBI. Participants received the Automated Neuropsychological Assessment Metrics (ANAM) to assess cognitive performance. Main findings indicate that despite normalized cognitive performance, chronic mTBI patients demonstrate increased rs-FC between the DMN and regions associated with the salience network (SN) and TPN compared to the control populations, as well as reduced strength of rs-FC within the DMN at the acute stage of injury. In addition, chronic mTBI patients demonstrate an imbalance in the ratio of CBF between nodes of the DMN and TPN. Furthermore, preliminary exploratory analysis suggests that compared to those without chronic PCS, patients with chronic PCS reveal an imbalance in the ratio of CBF between the DMN nodes and TPN nodes across multiple stages of recovery. Findings suggest that the altered network perfusion with the associated changes in rs-FC may be a possible predictor of which mTBI patients will develop chronic PCS. PMID:26241476

    Robertson et al. (JAMA 2014; 312:36-47) investigated the effects of two different thresholds of hemoglobin (Hb) to guide red blood cells transfusions (RBCT; 7 g/dL vs. 10 g/dL) in patients suffering from traumatic brain injury (TBI). In a two-center, controlled, open-label trial (from May 2006 and August 2012), comatose patients with a closed TBI were randomized within 6 hours since initial resuscitation to one of the two RBCT strategies and, in a factorial design (2x2), to receive erythropoietin (EPO) or placebo. Patients were excluded if they had a Glasgow Coma Scale (GCS) score of 3 with fixed and dilated pupils, penetrating trauma, pregnancy, life-threatening systemic injuries and severe preexisting diseases. A total of 200 patients (7 g/dL with [N.=49] or without EPO [N. =50]; 10 g/dL with [N.=53] or without EPO [N.=48]) were enrolled among 598 who were screened. There was no interaction between EPO and Hb thresholds on the primary outcome, which was the occurrence of favorable neurological outcome, assessed using the Glasgow Outcome Scale (GOS) at 6 months after the injury (favorable=GOS 4-5). Favorable outcome was similar between patients included in the 7 g/dL (37/87-43%) and the 10 g/dL group (31/94-33%) as if receiving EPO or placebo, even after adjustment for several covariates. Thromboembolic events were significantly more frequent in the group transfused at 10 g/dL (22/101 [22%] vs. 8/99 [8%]; P=0.009). We discussed how theses results might influence the management of such patients as well as the methodological limitations that underline the need for further investigations. PMID:25823463

    Background: Acute kidney injury (AKI) is a life threatening condition. Despite intensive care treatment the occurrence cannot be predicted as very little indicators exist for direct measurement when tubular epithelial cell injury takes place. We therefore searched for novel peptide indicators expressed at intracellular level at the proximal kidney tubule for its appearance in urine samples. Objectives: Establishing a test for urinary C20orf116 protein measurement. Patients and Methods: Generation of immunoreagents against C20orf116 also named DDRGK1. These were used to measure its presence in urine collected at 8-24 hours interval in a prospective study from 99 ICU patients at 4-6 time points. These patients received therapy because of serious infection and were categorized into 4 groups. Results: 1) Ten tested highly for C20orf116 undergoing AKI graded Failure or Loss (3210 ± 4268 ng/mL) according to RIFLE criteria, all requiring renal replacement therapy (RRT) out of them 9 died. 2) Six patients with pre-existing kidney disease developed AKI and required RRT but had much lower C20orf116 levels of (33 ± 19), two of them died. 3) In contrast, out of 11 patients undergoing AKI grade Risk or Injury, four tested positive for C20orf116 but to much lower extent (66 ± 43) who recovered fully. 4) Out of 72 patients 25 tested positive (18 ± 12 ng/mL) not fulfilling criteria of AKI but with serum creatinine (sCr) rises of 1.2-1.4 (n = 52). Healthy donors (n = 48) showed no detectable C20orf116 at any time point. Conclusions: C20orf116 excretion was detectable more than 24 hours before sCr rise could be measured; high level seemed to indicate severity of organ failure. PMID:27152292

    We developed a virtual reality (VR) driving simulator in order to safely evaluate and improve the driving ability of spinal injury patients. The simulator is composed of an actual car, a beam projector, and a large screen. For the interface of our driving simulator, an actual car was adapted and then connected to a computer. We equipped the car with hand control driving devices especially adapted for spinal injury patients. A beam projector was used so that the subjects could see the virtual scene on a large screen set up in front of them. The virtual environment (VE) consisted of 18 sections (e.g., a speed-limited road, a straight road, a curved road, a left turn) and each section was linked naturally to the next. The subjects selected for this trial were 10 normal drivers with valid driving licenses and 15 patients with thoracic or lumbar cord injuries who had prior driving experience. For evaluation, five driving skills were measured, including average speed, steering stability, centerline violations, traffic signal violations, and driving time in various road conditions such as straight and curved roads. The normal subjects manipulated the gas pedal and the brake with their feet, while the patients manipulated a hand control with their hands. After they finished driving the whole course, the participants answered the questions such as "How realistic did the virtual reality driving simulator seem to you?" and "How much was your fear reduced?" In this study, we found that the difference in manipulation method (i.e., the patient group's hand control versus the normal driver's foot controls) does not seem to influence relative performance in the VR driving simulator, though training to improve the use of hand controls in the VR driving simulator would be useful to reduce the fear that the patients feel while driving.

    Pressure injury guidelines recommend regular repositioning yet patients' mobility and repositioning patterns are unknown. An observational study using activity monitors was undertaken to describe the 24 h activity patterns of 84 hospitalized patients at risk of developing a pressure injury. The vast majority of participants' time was spent in the sedentary activity range (94% ± 3%) followed by the light range (5% ± 4 %). Patients changed their posture a median of 94 (interquartile range 48) time in the 24-h period (range 11-154), or ≈ 3.8 times per hour. Although a main focus for pressure injury prevention has been on repositioning, this study shows that patients with restricted mobility are actually moving quite often. Therefore, it might be appropriate to focus more attention on other pressure injury prevention strategies such as adequate nutrition, appropriate support surfaces and good skin care. PMID:24118408

    Purpose The aim of this study was to identify the risk factors that are predictive of poor outcomes in penetrating globe trauma. Patients and methods This retrospective case series evaluated 103 eyes that had been surgically treated for an open-globe injury from 2007 to 2010 at the eye clinic of the University of Virginia. A total of 64 eyes with complete medical records and at least 6 months of follow-up were included in the study. Four risk factors (preoperative best-corrected visual acuity [pre-op BCVA], ocular trauma score [OTS], zone of injury [ZOI], and time lapse [TL] between injury and primary repair) and three outcomes (final BCVA, monthly rate of additional surgeries [MRAS], and enucleation) were identified for analysis. Results Pre-op BCVA was positively associated with MRAS, final BCVA, and enucleation. Calculated OTS was negatively associated with the outcome variables. No association was found between TL and ZOI with the outcome variables. Further, age and predictor variable-adjusted analyses showed pre-op BCVA to be independently positively associated with MRAS (P=0.008) and with final BCVA (P<0.001), while the calculated OTS was independently negatively associated with final BCVA (P<0.001), but not uniquely associated with MRAS (P=0.530). Conclusion Pre-op BCVA and OTS are best correlated with prognosis in open-globe injuries. However, no conventional features reliably predict the outcome of traumatized eyes. PMID:27536059

    The role of aspirin as a risk factor in the occurrence of intracranial bleeding following head injury was investigated. Chronic subdural hematoma appears to be a suitable model for the evaluation of risk factors in the development of hemorrhage. The most common risk factors found in our study were, apart from age, chronic alcohol abuse (28%), consumption of cumarin-derivates (21%), aspirin (13%), and heparin (5%). A patient undergoing aspirin treatment must be considered at risk of development of chronic subdural hematoma. Aspirin should not be prescribed to patients with post-traumatic headaches.

    2013-01-01

    Objective Type 2 diabetes mellitus (T2DM) is associated with subclinical myocardial injury although the underlying mechanism is uncertain. We postulated that arterial stiffness, endothelial dysfunction and subclinical atherosclerosis may contribute to subclinical myocardial injury in patients with T2DM. Methods Serum high-sensitivity troponin I (hs-TNI) an indicator of myocardial injury, was measured in 100 patients with T2DM without clinical evidence of macrovascular disease and 150 age and gender-matched controls. Elevated hs-TnI was defined as follow (derived from the 99th percentile from controls): Male >11.1 ng/L; female >7.6 ng/L. Measures that may contribute to myocardial damage in patients with T2DM, including brachial-ankle pulse wave velocity (ba-PWV), brachial flow mediated dilatation (FMD) and carotid intima media thickness (IMT), were also assessed. Results The serum level of hs-TNI (5.7±9.2 μg/L vs. 3.2±1.9 μg/L, P< 0.01) and the prevalence of elevated hs-TNI (12% vs. 4%, P = 0.02) were significantly higher in patients with T2DM than controls. Patients with T2DM also had significantly worse ba-PWV (17.98±3.91ms-1 vs. 15.70±2.96 ms-1), brachial FMD (2.6±3.5% vs. 5.5±4.2%, P< 0.01) and carotid IMT (0.96±0.20 mm vs. 0.86±0.14 mm, P< 0.01). In patients with T2DM, hs-TNI was positively correlated with systolic blood pressure (r = 0.31, P<0.01), serum creatinine (r = 0.26, P = 0.01) and ba-PWV (r = 0.34, P< 0.01). Importantly, multiple regression revealed that only ba-PWV was independently associated with hs-TNI (β = 0.25, P = 0.04). Conclusion The results demonstrated an independent association between ba-PWV and hs-TNI in patients with T2DM with no clinical evidence of macrovascular disease. These findings suggest that increased arterial stiffness is closely related to subclinical myocardial injury in patients with T2DM. PMID:23799879

    Background The aim of this study is to give a description of the road traffic injuries (RTIs) characteristics of floating migrant population by comparing with those of local residents in a harbor city of China. Methods A population-based descriptive study was carried out between 2007 and 2010 with RTI patient records from the Fifth Center Hospital of Tianjin. Inpatient diagnoses of RTI patients were defined using the International Classification of Diseases, Tenth Revision (ICD-10) codes. We analyzed the demographics and general characteristics of RTI patients that were in the hospital during the four years. In order to compare the group differences between local resident patients and floating migrant patients, the distribution of their ages, diagnoses, severity of injuries, duration of inpatient stays, hospitalization cost were analyzed. Results People between the ages of 16 and 55 were the most likely to suffer RTIs. The floating migrant patients between the ages of 16 and 45 had a higher incidence of accidents, while local resident patients between 46 and 55 had a higher incidence of accidents. Compared to local resident patients, floating migrant patients were more vulnerable to open injuries and severe traffic injuries. With the severity of injuries ranked from mild to severe, floating migrant patients had lower duration of inpatient stay, but higher hospitalization costs compared to local resident patients. Conclusions Floating migrant patients had a different age distribution, severity of injuries, diseases, inpatient duration and hospitalization cost compared with local resident patients. Compared to local resident patients, floating migrants had a higher risk to RTIs and were more vulnerable to severer traffic accidents at lower ages. PMID:24475023

    Abstract In prior analyses of the effectiveness of methylprednisolone for the treatment of patients with acute traumatic spinal cord injuries (TSCIs), the prognostic importance of patients' neurological levels of injury and their baseline severity of impairment has not been considered. Our objective was to determine whether methylprednisolone improved motor recovery among participants in the Rick Hansen Spinal Cord Injury Registry (RHSCIR). We identified RHSCIR participants who received methylprednisolone according to the Second National Spinal Cord Injury Study (NASCIS-II) protocol and used propensity score matching to account for age, sex, time of neurological exam, varying neurological level of injury, and baseline severity of neurological impairment. We compared changes in total, upper extremity, and lower extremity motor scores using the Wilcoxon signed-rank test and performed sensitivity analyses using negative binomial regression. Forty-six patients received methylprednisolone and 1555 received no steroid treatment. There were no significant differences between matched participants for each of total (13.7 vs. 14.1, respectively; p=0.43), upper extremity (7.3 vs. 6.4; p=0.38), and lower extremity (6.5 vs. 7.7; p=0.40) motor recovery. This result was confirmed using a multivariate model and, as predicted, only cervical (C1–T1) rather than thoracolumbar (T2–L3) injury levels (p<0.01) and reduced baseline injury severity (American Spinal Injury Association [ASIA] Impairment Scale grades; p<0.01) were associated with greater motor score recovery. There was no in-hospital mortality in either group; however, the NASCIS-II methylprednisolone group had a significantly higher rate of total complications (61% vs. 36%; p=0.02) NASCIS-II methylprednisolone did not improve motor score recovery in RHSCIR patients with acute TSCIs in either the cervical or thoracic spine when the influence of anatomical level and severity of injury were included in the analysis.

    Introduction In 2006 the National Confidential Enquiry into Patient Outcome and Death undertook a large prospective study of trauma care, which revealed several findings pertaining to the management of head injuries in a sample of 493 patients. Methods Case note data were collected for all trauma patients admitted to all hospitals accepting emergencies in England, Wales, Northern Ireland and the Channel Islands over a three-month period. Severely injured patients with an injury severity score (ISS) of ≥16 were included in the study. The case notes for these patients were peer reviewed by a multidisciplinary group of clinicians, who rated the overall level of care the patient received. Results Of the 795 patients who met the inclusion criteria for the study, 493 were admitted with a head injury. Room for improvement in the level of care was found in a substantial number of patients (265/493). Good practice was found to be highest in high volume centres. The overall head injury management was found to be satisfactory in 84% of cases (319/381). Conclusions This study has shown that care for trauma patients with head injury is frequently rated as less than good and suggests potential long-term remedies for the problem, including a reconfiguration of trauma services and better provision of neurocritical care facilities.

    Deficits in social cognition are common after traumatic brain injury (TBI). However, little is known about how such deficits affect functional outcomes. The purpose of this study was to investigate the relationship between social cognition and functional outcomes in patients with TBI. We studied this relationship in 20 patients with TBI over the course of 1 year post-injury. Patients completed neurocognitive assessments and social cognition tasks. The social cognition tasks included an emotion-perception task and three theory of mind tasks: the Faux Pas test, Reading the Mind in the Eyes (Eyes) test, and the Moving-Shapes paradigm. The Craig Handicap Assessment and Reporting Technique was used to assess functional outcomes. Compared with our database of normal subjects, patients showed impairments in all social cognition tasks. Multiple regression analysis revealed that theory of mind ability as measured by the Eyes test was the best predictor of the cognitive aspects of functional outcomes. The findings of this pilot study suggest that the degree to which a patient can predict what others are thinking is an important measure that can estimate functional outcomes over 1 year following TBI.

    We have developed a tablet-based application, the High-Definition Fiber Tracking Report App, to enable clinicians and patients in research studies to see and understand damage from Traumatic Brain Injury (TBI) by viewing 2-dimensional and 3-dimensional images of their brain, with a focus on white matter tracts with quantitative metrics. The goal is to visualize white matter fiber tract injury like bone fractures; that is, to make the "invisible wounds of TBI" understandable for patients. Using mobile computing technology (iPad), imaging data for individual patients can be downloaded remotely within hours of a magnetic resonance imaging brain scan. Clinicians and patients can view the data in the form of images of each tract, rotating animations of the tracts, 3-dimensional models, and graphics. A growing number of tracts can be examined for asymmetry, gaps in streamline coverage, reduced arborization (branching), streamline volume, and standard quantitative metrics (e.g., Fractional Anisotropy (FA)). Novice users can learn to effectively navigate and interact with the application (explain the figures and graphs representing normal and injured brain tracts) within 15 minutes of simple orientation with high accuracy (96%). The architecture supports extensive graphics, configurable reports, provides an easy-to-use, attractive interface with a smooth user experience, and allows for securely serving cases from a database. Patients and clinicians have described the application as providing dramatic benefits in understanding their TBI and improving their lives. PMID:25747643

    Coping strategies in individuals suffering severe traumatic brain injury (TBI), cerebrovascular accidents (CVA), or hypoxic brain injury (HBI) were investigated in relation to apathy, depression, and lesion location. Seventy patients (27 with TBI, 30 with CVA, and 13 with HBI) filled in a coping questionnaire (COPE) and were evaluated with respect to apathy and depression. A comparison sample of 71 students also filled in COPE. Patients coping strategies were similar to the comparison group, but patients tended to display less differentiated coping styles. A factor analysis indicated two dimensions of coping in the patient sample; approach oriented and avoidance oriented coping. Approach and avoidance coping sum scores, based on subscales from the two factors, were positively correlated in the patient sample, but not in the comparison group. Lack of active approach oriented coping was associated with apathy, whereas avoidant coping was associated with depression. Coping styles were not related to lesion location. Apathy was related to subcortical and right hemisphere lesions. In bivariate analyses, depression was unrelated to lesion location, but, in a MANCOVA, avoidant coping, apathy and lesion location (left hemisphere lesions) contributed to the variance in positive depressive symptoms. The consistent relationships between coping strategies and neuropsychiatric symptoms were interpreted as two dimensions of adaptational behaviour: an active vs. passive dimension and a depression--distress-avoidance dimension.

    Background & Aims The drug-induced liver injury network (DILIN) is conducting a prospective study of patients with DILI in the United States. We present characteristics and subgroup analyses from the first 1257 patients enrolled in the study. Methods In an observational longitudinal study, we began collecting data on eligible individuals with suspected DILI in 2004, following them for 6 months or longer. Subjects were evaluated systematically for other etiologies, causes, and severity of DILI. Results Among 1257 enrolled subjects with suspected DILI, the causality was assessed in 1091 patients, and 899 were considered to have definite, highly likely, or probable DILI. Ten percent of patients died or underwent liver transplantation and 17% had chronic liver injury. In the 89 patients (10%) with pre-existing liver disease, DILI appeared to be more severe than in those without (difference not statistically significant; P=.09) and mortality was significantly higher (16% vs 5.2%; P<.001). Azithromycin was the implicated agent in a higher proportion of patients with pre-existing liver disease compared to those without liver disease (6.7% vs. 1.5%, p=0.006). Forty-one cases with latency ≤ 7 days were caused predominantly by antimicrobial agents (71%). Two most common causes for 60 DILI cases with latency >365 days were nitrofurantoin (25%) or minocycline (17%). There were no differences in outcomes of patients with short vs long latency of DILI. Compared to individuals younger than 65 y, individuals 65 y or older (n=149) were more likely to have cholestatic injury, although mortality and rate of liver transplantation did not differ. Nine patients (1%) had concomitant severe skin reactions; implicated agents were lamotrigine, azithromycin, carbamazepine, moxifloxacin, cephalexin, diclofenac, and nitrofurantoin. Four of these patients died. Conclusion Mortality from DILI is significantly higher in individuals with pre-existing liver disease or concomitant severe skin

    Objective/background A newly designed Spinal Cord Unit (SCU) was set up at the Orthopedic Traumatology Center (OTC), Turin, Italy, in July 2007. With the relocation of the SCU came the need to reorganize and improve the delivery of its services. The study reported here is a preliminary part of a project entitled ‘Experimentation and evaluation of personalized healthcare for patients with spinal cord injury’, which is a component of an overarching program of targeted research into healthcare funded by the Piedmont Region in 2006. The aim of this study was to assess the perception of care by patients with spinal cord injury (SCI) by collecting important data in order to determine whether an integrated and personalized care pathway could be effective both in hospital and in a rehabilitation setting. Design Qualitative research study. The interview format was based on a narrative approach. Methods Qualitative in-depth semi-structured interviews were conducted with 21 patients with SCI. Qualitative content analysis was used to identify categories and themes arising from the data. Results Six main categories emerged from the perspectives of patients: expectations of rehabilitation care, impact and welcome, relationship with nurses and their involvement in treatment, relationship with physical therapists and participation in rehabilitation programs, relationship with physicians and their availability and attendance, and imparting of information on injury and rehabilitation outcomes. Care was the aspect new patients admitted to the SCU found most important. When closer relationships with staff formed, the healthcare professionals became an essential support. Patients with SCI commonly stated that receiving explicit information was necessary for accepting their condition. Conclusions Analysis of the patients' perceptions revealed a wealth of details on their experience in the SCU and the need for flexible planning of care time in particular.

    Background Burn injuries are associated with hyperglycemia leading to increased incidence of infections with pneumonia being one of the most prominent and adverse complication. Recently, various studies in critically ill patients indicated that increased pulmonary glucose levels with airway/blood glucose threshold over 150 mg/dl lead to an overwhelming growth of bacteria in the broncho-pulmonary system, subsequently resulting in an increased risk of pulmonary infections. The aim of the present study was to determine whether a similar cutoff value exists for severely burned pediatric patients. Methods One-hundred six severely burned pediatric patients were enrolled in the study. Patients were divided in two groups: high (H) defined as daily average glucose levels >75% of LOS >150 mg/dl), and low (L) with daily average glucose levels >75% of the LOS <150 mg/dl). Incidences of pneumonia, atelectasis, and acute respiratory distress syndrome (ARDS) were assessed. Incidence of infections, sepsis, and respiratory parameters were recorded. Blood was analyzed for glucose and insulin levels. Statistical analysis was performed using Student’s t-test and chi-square test. Significance was set at p<0.05. Results Patient groups were similar in demographics and injury characteristics. Pneumonia in patients on the mechanical ventilation (L: 21% H: 32%) and off mechanical ventilation (L: 5% H: 15%), as well as ARDS were significantly higher in the high group (L: 3% H: 19%), p<0.05, while atelectasis was not different. Patients in the high group required significantly longer ventilation compared to low patients (p<0.05). Furthermore, incidence of infection and sepsis were significantly higher in the high group, p<0.05. Conclusion Our results indicate that systemic glucose levels over 150 mg/dl are associated with a higher incidence of pneumonia confirming the previous studies in critically ill patients.

    The clinical management of paraplegic patients is more complex than in able-bodied subjects. Spinal cord injury (SCI) affects younger, active people more often than the elderly during high-energy fall or traffic accidents. In order to return to work after suffering an SCI, patients need to regain their functional independence, especially their ability to drive. The literature lacks strong evidence addressing the surgical solutions in severe knee arthrosis in paralyzed patients after SCI. We present a favourable outcome of total knee arthroplasty (TKA) of a stiff knee in extension in a man with T12 grade C paraplegia after SCI. We describe an effective rehabilitation protocol after knee arthroplasty in patient with damage to the spinal cord. Several factors should be taken into account before performing surgery: 1. ability of regaining some of spinal cord locomotor function through intensive gait rehabilitation in SCI patients, 2. presence of muscle imbalance and knee contractures combined with a risk of bone fracture resulting from intensive postoperative rehabilitation, 3. the impaired microvasculature of the skin and subcutaneous tissues and increased risk of occlusion occurrence of the capillaries and small vessels of the leg, 4. higher prevalence of secondary infections via urinary entry sites in patients after SCI, 5. patient's strong determination and willingness to undergo the arthroplasty procedure. TKA might be considered in selected paralyzed patients after SCI, especially in those with severe arthrosis as well as significant knee contractures. Our study reveals the advantage of performing TKA in improving functional state in patients with cord injury. PMID:25748667

    Summary Background The objective of our study was to evaluate a goal-driven strategic plan for the step-by-step rehabilitation of traumatic brain injury (TBI) patients, with effectiveness measured in terms of quality of life, as compared to patients treated according to a standard, progressive rehabilitation program. Material/Methods We studied 40 patients after TBI awakened from a long-term coma. The patients were divided into two equal groups: a control group (n=20) involving patients treated before the introduction of the strategic approach, and an experimental group (n=20) involving patients rehabilitated under the strategic approach. In evaluating the effectiveness of rehabilitation we used a structured interview with clinical observation and a scale for assessing the quality of life of patients after TBI. Results The deterioration in the quality of life of TBI patients is mainly related to difficulties in satisfying physiological needs, self-care, reduced mobility and disorders of cognitive, regulatory, and social functions. In both groups, the feature most susceptible to rehabilitation related change was movement, while the least susceptible functions were associated with the use of different means of transport. This change is significantly greater in persons in the experimental group, as compared to controls. Conclusions We found that a rehabilitation program controlled by a strategic plan, with the cooperation of the patient, is more effective in improving the quality of life, as the patient is more self-motivated to individually designed objectives.

    Objective The goal of this study was to determine the incidence of soft-tissue injuries in patients with posterolateral tibial plateau fractures. Methods The data of 265 patients who had sustained posterolateral tibial plateau fractures between May 2009 and Aug 2014 were retrospectively reviewed using a picture archiving and communication system. Fractures were classified according to the Schatzker, AO/OTA, and quadrant classification systems. Soft-tissue injuries, including anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), lateral collateral ligament (LCL), medial collateral ligament (MCL), lateral meniscus, and medial meniscus injuries, were assessed using magnetic resonance imaging (MRI) data. Results The overall incidence of ACL and PCL tears was 80 and 36%, respectively. Nine (36%) patients sustained ACL footprint avulsions and three (12%) had complete ACL tears. A total of 19 (76%) patients had LCL injuries, and 15 (64%) had MCL injuries. The incidence of lateral meniscus tears was 48%, while that of medial meniscus tears was 4%. Conclusion Posterolateral tibial plateau fractures were associated with a high incidence of soft-tissue injuries, especially ACL footprint avulsions and lateral meniscus tears. The preoperative MRI examination was important for surgeons to decide whether the ligament and meniscal injuries should be treated simultaneously with the repair of the bone fractures. PMID:27183240

    Objective To investigate improved dysphagia after the decannulation of a tracheostomy in patients with brain injuries. Methods The subjects of this study are patients with brain injuries who were admitted to the Department of Rehabilitation Medicine in Myongji Hospital and who underwent a decannulation between 2012 and 2014. A video fluoroscopic swallowing study (VFSS) was performed in order to investigate whether the patients' dysphagia had improved. We measured the following 5 parameters: laryngeal elevation, pharyngeal transit time, post-swallow pharyngeal remnant, upper esophageal width, and semisolid aspiration. We analyzed the patients' results from VFSS performed one month before and one month after decannulation. All VFSS images were recorded using a camcorder running at 30 frames per second. An AutoCAD 2D screen was used to measure laryngeal elevation, post-swallow pharyngeal remnant, and upper esophageal width. Results In this study, a number of dysphagia symptoms improved after decannulation. Laryngeal elevation, pharyngeal transit time, and semisolid aspiration showed no statistically significant differences (p>0.05), however after decannulation, the post-swallow pharyngeal remnant (pre 37.41%±24.80%, post 21.02%±11.75%; p<0.001) and upper esophageal width (pre 3.57±1.93 mm, post 4.53±2.05 mm; p<0.001) showed statistically significant differences. Conclusion When decannulation is performed on patients with brain injuries who do not require a ventilator and who are able to independently excrete sputum, improved esophageal dysphagia can be expected.

    Background Guidelines recommend that patients with brain trauma with a Glasgow Coma Scale (GCS) score of less than 9 should have an airway established. Hypoxia, hypotension and hypertension as well as hypoventilation and hyperventilation may worsen outcome in these patients. Objectives The objectives were to investigate guideline adherence, reasons for nonadherence and the incidences of complications related to prehospital advanced airway management in patients with traumatic brain injury. Materials and methods We prospectively collected data from eight anaesthesiologist-staffed prehospital critical care teams in the Central Denmark Region according to the Utstein-style template. Results Among 1081 consecutive prehospital advanced airway management patients, we identified 54 with a traumatic brain injury and an initial GCS score of less than 9. Guideline adherence in terms of airway management was 92.6%. The reasons for nonadherence were the patient’s condition, anticipated difficult airway management and short distance to the emergency department. Following rapid sequence intubation (RSI), 11.4% developed oxygen saturation below 90%, 9.1% had a first post-RSI systolic blood pressure below 90 mmHg and 48.9% had a first post-RSI systolic blood pressure below 120 mmHg. The incidence of hypertension following prehospital RSI was 4.5%. The incidence of postendotracheal intubation hyperventilation was as high as 71.1%. Conclusion The guideline adherence was high. The incidences of post-RSI hypoxia and systolic blood pressure below 90 compare with the results reported from other physician-staffed prehospital services. The incidence of systolic blood pressure below 120 as well as that of hyperventilation following prehospital endotracheal intubation in patients with traumatic brain injury call for a change in our current practice.

    Liver injury is a frequent, serious complication of allogeneic hematopoietic cell transplantation (HCT) following myeloablative preparative regimens. We sought to determine the frequency and severity of hepatic injury after nonmyeloablative conditioning and its relationship to outcomes. One hundred ninety-three consecutive patients who received 2 Gy total body irradiation with or without fludarabine were evaluated for end points related to liver injury. Patients with diseases treatable by HCT who were ineligible for conventional myeloablative allogeneic HCT because of advanced age and/or comorbid conditions were included. Fifty-one patients (26%) developed hyperbilirubinemia of 68.4 microM (4 mg/dL) or greater, most commonly resulting from cholestasis due to graft-versus-host disease (GVHD) or sepsis. Pretransplantation factors associated with liver dysfunction were a diagnosis of aggressive malignancy (hazard ratio [HR] 1.9; P =.04) and the inclusion of fludarabine in the conditioning regimen (HR 1.8; P =.07). Overall survival at 1 year was superior for patients who had maximal serum bilirubin levels in the normal (78%) or minimally elevated (22.23-66.69 microM [1.3-3.9 mg/dL]) ranges (69%) compared with those in the 68.4 to 117.99 microM (4-6.9 mg/dL; 20%), 119.7 to 169.29 microM (7.0-9.9 mg/dL; 17%), and 171.0 microM (10 mg/dL; 19%) or greater groups. In summary, significant jaundice occurred in 26% of patients and was predominantly due to cholestasis resulting from GVHD and/or sepsis. Aggressive malignancies (mainly advanced disease) and later development of jaundice after transplantation predicted inferior survival. PMID:12969980

    Objective To determine the effect of robotic-assisted gait training (RAGT) compared to conventional overground training. Methods Sixty patients with motor incomplete spinal cord injury (SCI) were included in a prospective, randomized clinical trial by comparing RAGT to conventional overground training. The RAGT group received RAGT three sessions per week at duration of 40 minutes with regular physiotherapy in 4 weeks. The conventional group underwent regular physiotherapy twice a day, 5 times a week. Main outcomes were lower extremity motor score of American Spinal Injury Association impairment scale (LEMS), ambulatory motor index (AMI), Spinal Cord Independence Measure III mobility section (SCIM3-M), and walking index for spinal cord injury version II (WISCI-II) scale. Results At the end of rehabilitation, both groups showed significant improvement in LEMS, AMI, SCIM3-M, and WISCI-II. Based on WISCI-II, statistically significant improvement was observed in the RAGT group. For the remaining variables, no difference was found. Conclusion RAGT combined with conventional physiotherapy could yield more improvement in ambulatory function than conventional therapy alone. RAGT should be considered as one additional tool to provide neuromuscular reeducation in patient with incomplete SCI. PMID:25566469

    Periventricular leucomalacia has long been investigated as a leading cause of motor and cognitive dysfunction in patients with spastic diplegic cerebral palsy. However, patients with periventricular leucomalacia on conventional magnetic resonance imaging do not always have motor dysfunction and preterm children without neurological abnormalities may have periventricular leucomalacia. In addition, it is uncertain whether descending motor tract or overlying cortical injury is related to motor impairment. To investigate the relationship between motor pathway injury and motor impairment, we conducted voxelwise correlation analysis using tract-based spatial statistics of white matter diffusion anisotropy and voxel-based-morphometry of grey matter injury in patients with periventricular leucomalacia and spastic diplegia (n = 43, mean 12.86 ± 4.79 years, median 12 years). We also evaluated motor cortical and thalamocortical connectivity at resting state in 11 patients using functional magnetic resonance imaging. The functional connectivity results of patients with spastic diplegic cerebral palsy were compared with those of age-matched normal controls. Since γ-aminobutyric acid(A) receptors play an important role in the remodelling process, we measured neuronal γ-aminobutyric acid(A) receptor binding potential with dynamic positron emission tomography scans (n = 27) and compared the binding potential map of the patient group with controls (n = 20). In the current study, white matter volume reduction did not show significant correlation with motor dysfunction. Although fractional anisotropy within most of the major white matter tracts were significantly lower than that of age-matched healthy controls (P < 0.05, family wise error corrected), fractional anisotropy mainly within the bilateral corticospinal tracts and posterior body and isthmus of the corpus callosum showed more significant correlation with motor dysfunction (P < 0.03) than

    Injury to the pancreas, because of its retroperitoneal location, is a rare occurrence, most commonly seen with penetrating injuries (gun shot or stab wounds). Blunt trauma to the pancreas accounts for only 25% of the cases. Pancreatic injuries are associated with high morbidity and mortality due to accompanying vascular and duodenal injuries. Pancreatic injuries are not always easy to diagnose resulting in life threatening complications. Physical examination as well as serum amylase is not diagnostic following blunt trauma. Computed tomography (CT) scan can delineate the injury or transaction of the pancreas. Endoscopic retrograde pancreaticography (ERCP) is the main diagnostic modality for evaluation of the main pancreatic duct. Unrecognized ductal injury leads to pancreatic pseudocyst, fistula, abscess, and other complications. Management depends upon the severity of the pancreatic injury as well as associated injuries. Damage control surgery in hemodynamic unstable patients reduces morbidity and mortality. PMID:20016434

    Increasing evidence suggests that antibiotic dosing in critically ill patients with acute kidney injury (AKI) often does not achieve pharmacodynamic goals, and the continued high mortality rate due to infectious causes appears to confirm these findings. Although there are compelling reasons why clinicians should use more aggressive antibiotic dosing, particularly in patients receiving aggressive renal replacement therapies, concerns for toxicity associated with higher doses are real. The presence of multisystem organ failure and polypharmacy predispose these patients to drug toxicity. This article examines the pharmacokinetic and pharmacodynamic consequences of critical illness, AKI, and renal replacement therapy and describes potential solutions to help clinicians give "enough but not too much" in these very complicated patients.

    Nine patients with spinal cord injury (SCI) and large pressure ulcers and other possible complications, were evaluated by computed tomography (CT), conventional radiography, tomography, bone scanning, gallium scanning, and sonography. CT revealed the depth, extent, and relationship of the ulcer-bed to the underlying structures in all 9 patients. CT also positively identified unsuspected intra- and extra-pelvic abscess and pelvic osteomyelitis in 4 patients each. Other modalities identified only 2 of these complications. We believe CT is the modality of choice for evaluation of these complications in SCI patients, because of its superior ability in evaluation of pressure sores and detection of pathologic changes in soft tissue and bone in the pelvic region.

    Transfusion-related acute lung injury (TRALI) is a serious adverse reaction of transfusion, and presents as hypoxemia and non-cardiogenic pulmonary edema within 6 hours of transfusion. A 14-year-old primigravida woman at 34 weeks of gestation presented with upper abdominal pain without dyspnea. Because she showed the syndrome of HELLP (hemolysis, elevated liver enzymes, and low platelet count), an emergency cesarean section delivery was performed, and blood was transfused. In the case of such patients, clinicians should closely observe the patient's condition at least during the 6 hours while the patient receives blood transfusion, and should suspect TRALI if the patient complains of respiratory symptoms such as dyspnea. Furthermore, echocardiography should be performed to distinguish between the different types of transfusion-related adverse reactions. PMID:26885326

    2015-01-01

    Background Bomb blast injuries result in premature deaths and burdening of healthcare systems. The objective of this study was to explore the characteristics and outcome of patients presenting to the emergency departments in Pakistan with bomb blast injuries. Methods Active surveillance was conducted in seven major emergency departments of Pakistan from November 2010-March 2011. All the sites are tertiary care urban centers. All the patients who presented to the hospital's emergency department (ED) following a bomb blast injury as per self-report or the ambulance personnel were included in the study. Frequency of demographics, injury pattern, and outcomes were calculated. Results A total of 103 patients with bomb blast injuries presented to the selected emergency departments. The median age of patients was 30 years. Around three-fourth of the patients were males (n = 74, 74.7%). Most of the bomb blast patients were seen in Peshawar (n = 41, 39.8%) and Karachi city (n = 31, 30.1%) and the most common mode of arrival was non-ambulance transport (n = 71, 76.3%). Upper limb injuries (n = 12, 40%) were common in the under 18 age group and lower limb injuries (n = 31, 39.2%) in the 18 years and above group. There were a total of 8 (7.7%) deaths reported out of these 103 patients. Conclusion Bomb blast injuries in Pakistan generally affect young males. Non-ambulance transport is the most common way to access emergency departments (ED). Overall ED mortality is high and capturing data during a disaster in an emergency department is challenging.

    Despite the potentially devastating impact of missed cervical spine injuries (CI), there continues to be a large disparity in how institutions attempt to make the diagnosis. To better streamline the approach among institutions, understanding incidence and risk factors across the country is paramount. We evaluated the incidence and risk factors of CI using the National Trauma Databank for 2008 and 2009. We performed a retrospective review of the National Trauma Databank for 2008 and 2009 comparing patients with and without CI. We then performed subset analysis separating injury by patients with and without fracture and ligamentous injury. There were a total of 591,138 patients included with a 6.2 per cent incidence of CI. Regression found that age, Injury Severity Score, alcohol intoxication, and specific mechanisms of motor vehicle crash (MVC), motorcycle crash (MCC), fall, pedestrian stuck, and bicycle were independent risk factors for overall injury (P < 0.0001). Patients with CI had longer intensive care unit (8.5 12.5 vs 5.1 7.7) and hospital lengths of stay (days) (9.6 14.2 vs 5.3 8.1) and higher mortality (1.2 per cent vs 0.3%), compared with those without injury (P < 0.0001). There were 33,276 patient with only fractures for an incidence of 5.6 per cent and 1875 patients with ligamentous injury. Just over 6 per cent of patients suffer some form of CI after blunt trauma with the majority being fractures. Higher Injury Severity Score and MVC were consistent risk factors in both groups. This information will assist in devising an algorithm for clearance that can be used nationally allowing for more consistency among trauma providers. PMID:26350665

    Objective To assess the use of urologic investigations among traumatic spinal cord injury (TSCI) patients. Methods This is a retrospective cohort study from Ontario, Canada. We included all adult TSCI patients injured between 2002 and 2012. The primary outcome was the frequency of urodynamic testing, renal imaging, and cystoscopy. Primary exposure was the year of injury. The impact of age, sex, comorbidity, socioeconomic status, and lesion level was assessed with Cox regression models. Results One thousand five hundred and fifty one incident TSCI patients were discharged from a rehabilitation hospital. The median follow-up time of this cohort was 5.0 years (interquartile range =2.9–7.5). At least one urodynamics, renal imaging, or cystoscopy was performed during follow-up for 50%, 80%, and 48% of the cohort, respectively. The overall rate of these tests was 0.22, 0.60, and 0.22 per person-year of follow-up. The proportion of patients who had regular, yearly urodynamics (<2%), renal imaging (6%), or cystoscopy (<2%) was low. There were no significant linear trends in the use of these tests over the 10-year study period. Urodynamics were significantly less likely to be performed in patients over 65 years of age (hazard ratio [HR] =0.63, P<0.01) and those with a higher level of comorbidity (HR =0.72, P<0.01). Patients with quadriplegia were significantly less likely to receive any of the investigations compared to those with paraplegia. Conclusion Renal imaging is done at least once for the majority of patients with TSCI; however, only half undergo urodynamics or cystoscopy. Few patients have regular urologic testing. The reality of urologic testing after TSCI is very different from urologist’s ideals and practice guidelines. PMID:26955621

    Mild traumatic brain injury (TBI) is often an invisible injury that is poorly understood and its sequelae can be difficult to diagnose. Recent neuroimaging studies on patients diagnosed with mild TBI (mTBI) have demonstrated an increase in hyperintense brain lesions on T2-weighted MR images. This paper presents an in-depth analysis of the multi-modal and morphological properties of T2 hyperintensity lesions among service members diagnosed with mTBI. A total of 790 punctuate T2 hyperintensity lesions from 89 mTBI subjects were analyzed and used to characterize the lesions based on different quantitative measurements. Morphological analysis shows that on average, T2 hyperintensity lesions have volumes of 23mm3 (+/-24.75), a roundness measure of 0.83 (+/-0.08) and an elongation of 7.90 (+/-2.49). The frontal lobe lesions demonstrated significantly more elongated lesions when compared to other areas of the brain.

    Transfusion-related acute lung injury (TRALI) is a serious clinical syndrome associated with the transfusion of plasmacontaining blood components. Recently, TRALI has come to be recognized as the leading cause of transfusion-related mortality. This complication typically presents as shortness of breath, hypoxemia, hypotension, fever, and non cardiogenic pulmonary edema, occurring within 6 h after transfusion. Although the mechanism of TRALI has not been exactly known, it has been associated with human leukocyte antigen antibodies and with biologically active mediators in stored cellular blood components. We, hereby, present a case of a patient with dengue fever who developed acute lung injury (ALI), presumably TRALI, after transfusion of platelet concentrates. He was treated with supportive measures and mechanical ventilation. Greater knowledge and increased awareness especially amongst the clinicians regarding TRALI is needed for prevention and treatment of this potentially severe complication of blood/component transfusion.

    Well-known as one of the main sources of cerebrospinal fluid (CSF), the choroid plexuses have been, and still remain, a relatively understudied tissue in neuroscience. The choroid plexus and CSF (along with the blood-brain barrier proper) are recognized to provide a robust protective effort for the brain: a physical barrier to impede entrance of toxic metabolites to the brain; a “biochemical” barrier that facilitates removal of moieties that circumvent this physical barrier; and buoyant physical protection by CSF itself. In addition, the choroid plexus-CSF system has been shown to be integral for normal brain development, central nervous system (CNS) homeostasis, and repair after disease and trauma. It has been suggested to provide a stem-cell like repository for neuronal and astrocyte glial cell progenitors. By far, the most widely recognized choroid plexus role is as the site of the blood-CSF barrier, controller of the internal CNS microenvironment. Mechanisms involved combine structural diffusion restraint from tight junctions between plexus epithelial cells (physical barrier) and specific exchange mechanisms across the interface (enzymatic barrier). The current hypothesis states that early in development this interface is functional and more specific than in the adult, with differences historically termed as “immaturity” actually correctly reflecting developmental specialization. The advanced knowledge of the choroid plexus-CSF system proves itself imperative to understand a range of neurological diseases, from those caused by plexus or CSF drainage dysfunction (e.g., hydrocephalus) to more complicated late-stage diseases (e.g., Alzheimer's) and failure of CNS regeneration. This review will focus on choroid plexus development, outlining how early specializations may be exploited clinically. PMID:25784848

    Pain in pancreatic cancer is often a major problem of treatment. Administration of opioids is frequently limited by side effects or insufficient analgesia. Endoscopic ultrasound-guided celiac plexus neurolysis (EUS-CPN) represents an alternative for the palliative treatment of visceral pain in patients with pancreatic cancer. This review focuses on the indications, technique, outcomes of EUS-CPN and predictors of pain relief. EUS-CPN should be considered as the adjunct method to standard pain management. It moderately reduces pain in pancreatic cancer, without eliminating it. Nearly all patients need to continue opioid use, often at a constant dose. The effect on quality of life is controversial and survival is not influenced. The approach could be done in the central position of the celiac axis, which is easy to perform, or in the bilateral position of the celiac axis, with similar results in terms of pain alleviation. The EUS-CPN with multiple intraganglia injection approach seems to have better results, although extended studies are still needed. Further trials are required to enable more confident conclusions regarding timing, quantity of alcohol injected and the method of choice. Severe complications have rarely been reported, and great care should be taken in choosing the site of alcohol injection. PMID:24415863

    Background: Blunt chest trauma (BCT) poses significant morbidity and mortality worldwide. Objectives: We investigated the clinical presentation and outcome of BCT related to road traffic accidents (RTA). Patients and Methods: A retrospective observational analysis for patients who sustained BCT secondary to RTA in terms of motor vehicle crash (MVC) and pedestrian-motor vehicle accidents (PMVA) who were admitted to the trauma center at Hamad general hospital, Doha, Qatar, between 2008 and 2011. Results: Of 5118 traumatic injury cases, 1004 (20%) were found to have BCT secondary to RTA (77% MVC and 23% PMVA). The majority were males (92%), and expatriates (72%). Among MVCs, 84% reported they did not use protective devices. There was a correlation between chest abbreviated injury score (AIS) and injury severity scoring (ISS) (r = 0.35, r2 = 0.12, P < 0.001). Regardless of mechanism of injury (MOI), multivariate analysis showed that the head injury associated with chest AIS and ISS was a predictor of mortality in BCT. Overall mortality was 15%, and the highest rate was observed within the first 24 hours post-trauma. Conclusions: Blunt chest trauma from RTA represents one-fifth of the total trauma admissions in Qatar, with a high overall mortality. Pedestrians are likely to have more severe injuries and higher fatality rates than MVC victims. Specific injury prevention programs focusing on road safety should be implemented to minimize the incidence of such preventable injuries. PMID:27148499

    The caffeine test measures the activity of cytochrome p450 (CYP1A2) which is a major enzyme involved in the activation of flutamide. The usefulness of this test in predicting flutamide-induced hepatic injury in patients with prostate cancer was examined. The subjects were: (1). five patients whose aspartate aminotransferase (AST) or alanine aminotransferase (ALT) level rose to 100 IU/l or higher following the start of flutamide (moderately injured group); (2). four patients whose AST and ALT levels were higher than normal but less than 100 IU/l (mildly injured group); and (3). two patients whose hepatic function remained normal (normal group). The subjects were each given canned coffee to drink. Urinary caffeine (137X), paraxanthine (17X) and 1, 7-dimethyluric acid (17U) levels were measured 4-5 h later. The metabolite ratio, (17U+17X)/137X, was calculated to serve as an indicator of CYP1A2 activity. The metabolite ratio for the moderately injured group (3.98+/-1.56) and the mildly injured group (5.55+/-1.42) were lower than that for the normal group (9.56). The results suggest that a decrease in CYP1A2 activity is involved in the onset of flutamide-induced hepatic injury, and that the caffeine test seems to provide a useful means of its prediction.

    Background The aim of this study was to investigate the use of transcranial Doppler (TCD) for diagnosis of brain death in patients with severe cerebral injury. Material/Methods This retrospective study enrolled 42 patients based on inclusion and exclusion criteria. All patients were divided into either the brain death group or the survival group according to prognosis. Blood flow of the brain was examined by TCD and analyzed for spectrum changes. The average blood flow velocity (Vm), pulse index (PI), and diastolic blood flow in reverse (RDF) were recorded and compared. Results The data demonstrated that the average speed of bilateral middle cerebral artery blood flow in the brain death group was significantly reduced (P<0.05). However, the PI of the brain death group increased significantly. Moreover, RDF spectrum and nail-like sharp peak spectrum of the brain death group was higher than in the survival group. Conclusions Due to its simplicity, high repeatability, and specificity, TCD combined with other methods is highly valuable for diagnosis of brain death in patients with severe brain injury.

    Ischemia is a common and deleterious secondary injury following traumatic brain injury (TBI). A great challenge for the treatment of TBI patients in the neurointensive care unit (NICU) is to detect early signs of ischemia in order to prevent further advancement and deterioration of the brain tissue. Today, several imaging techniques are available to monitor cerebral blood flow (CBF) in the injured brain such as positron emission tomography (PET), single-photon emission computed tomography, xenon computed tomography (Xenon-CT), perfusion-weighted magnetic resonance imaging (MRI), and CT perfusion scan. An ideal imaging technique would enable continuous non-invasive measurement of blood flow and metabolism across the whole brain. Unfortunately, no current imaging method meets all these criteria. These techniques offer snapshots of the CBF. MRI may also provide some information about the metabolic state of the brain. PET provides images with high resolution and quantitative measurements of CBF and metabolism; however, it is a complex and costly method limited to few TBI centers. All of these methods except mobile Xenon-CT require transfer of TBI patients to the radiological department. Mobile Xenon-CT emerges as a feasible technique to monitor CBF in the NICU, with lower risk of adverse effects. Promising results have been demonstrated with Xenon-CT in predicting outcome in TBI patients. This review covers available imaging methods used to monitor CBF in patients with severe TBI.

    Background: Patients with traumatic brain injury (TBI) usually have mood and anxiety symptoms secondary to their brain injury. Exercise may be a cost-effective intervention for the regulation of the affective responses of this population. However, there are no studies evaluating the effects of exercise or the optimal intensity of exercise for this clinical group. Methods: Twelve male patients with moderate or severe TBI [mean age of 31.83 and SD of 9.53] and 12 age- and gender-matched healthy volunteers [mean age of 30.58 and SD of 9.53] participated in two sessions of exercise of high and moderate-intensity. Anxiety and mood was evaluated, and subjective assessment of experience pre- and post-exercise was assessed. A mixed between and within-subjects general linear model (GLM) analysis was conducted to compare groups [TBI, control] over condition [baseline, session 1, session 2] allowing for group by condition interaction to be determined. Planned comparisons were also conducted to test study hypotheses. Results: Although no group by condition interaction was observed, planned comparisons indicated that baseline differences between patients and controls in anxiety (Cohens’ d = 1.80), tension (d = 1.31), depression (d = 1.18), anger (d = 1.08), confusion (d = 1.70), psychological distress (d = 1.28), and physical symptoms (d = 1.42) disappear after one session of exercise, independently of the intensity of exercise. Conclusion: A single-section of exercise, regardless of exercise intensity, had a positive effect on the affective responses of patients with TBI both by increasing positive valence feelings and decreasing negative ones. Exercise can be an easily accessible intervention that may alleviate depressive symptoms related to brain injury. PMID:26161074

    Background/objective To examine associations of patient characteristics along with treatment quantity delivered by seven clinical disciplines during inpatient spinal cord injury (SCI) rehabilitation with outcomes at rehabilitation discharge and 1-year post-injury. Methods Six inpatient SCI rehabilitation centers enrolled 1376 patients during the 5-year SCIRehab study. Clinicians delivering standard care documented details of treatment. Outcome data were derived from SCI Model Systems Form I and II and a project-specific interview conducted at approximately 1-year post-injury. Regression modeling was used to predict outcomes; models were cross-validated by examining relative shrinkage of the original model R2 using 75% of the dataset to the R2 for the same outcome using a validation subsample. Results Patient characteristics are strong predictors of outcome; treatment duration adds slightly more predictive power. More time in physical therapy was associated positively with motor Functional Independence Measure at discharge and the 1-year anniversary, CHART Physical Independence, Social Integration, and Mobility dimensions, and smaller likelihood of rehospitalization after discharge and reporting of pressure ulcer at the interview. More time in therapeutic recreation also had multiple similar positive associations. Time spent in other disciplines had fewer and mixed relationships. Seven models validated well, two validated moderately well, and four validated poorly. Conclusion Patient characteristics explain a large proportion of variation in multiple outcomes after inpatient rehabilitation. The total amount of treatment received during rehabilitation from each of seven disciplines explains little additional variance. Reasons for this and the phenomenon that sometimes more hours of service predict poorer outcome, need additional study. Note This is the first of nine articles in the SCIRehab series. PMID:23318033
