    Non-union of radial neck fractures is not common in adults, and surgical treatment is rarely required. This case report documents non-union of the radial neck with persistent pain around the elbow joint and tenderness over the neck of the radius, limited range of motion for 12 months. The authors performed an iliac bone graft and temporary K-wire fixation for non-union of the radial neck after an isolated radial neck fracture. A 54-year-old woman slipped with her hand outstretched 12 months prior to presentation. She was diagnosed with a radial neck fracture, but her injury was eventually diagnosed as a non-union fracture, and she was transferred to our hospital. The patient had tenderness of the radial head and neck and an increasing tendency of pain in the forearm during external rotation with resistance. Flexion was a maximum of 80°, extension was limited to 20°, and internal rotation and external rotation were decreased to 60°. On plain radiographs, a clear radiolucent shadow was present between the bone fragment and radius. After the autogenous iliac bone graft, a temporary K-wire was fixed, and at eight weeks postoperatively, the bone was united. The patient is in the month 24 of postoperative follow-up and is able to perform daily activities without tenderness. If elbow joint pain, tenderness, and limitation of range of motion are present in non-union of radial neck fracture, surgical treatment is necessary. If there is no injury to the ligament around the elbow or instability, the authors consider bone graft and temporary K-wire fixation as an excellent treatment option for bony union and early exercise of the joint.

    The aim of this study was to address the inconsistency regarding the operative treatment of Rockwood type III acromioclavicular joint separation. We compared results after single- and double TightRope(®) reduction with results after acromioclavicular transfixation via K-wires only and additional ligament augmentation in acute acromioclavicular (AC) joint separations graded Rockwood type III, and hypothesized that the TightRope(®) technique leads to better clinical and radiological results. We conducted a retrospective clinical cohort study and included 42 consecutive patients (mean age 43 years [24-66]) diagnosed and operatively treated between 2004 and 2012 (mean follow-up was 54.6 months [15-118]). Specific shoulder scores as well as scores reflecting the patients' overall mental and physical health status were used. Radiological evaluation was also performed. The SF12 test revealed comparability between all subgroups. Specific shoulder tests and a visual analogue scale demonstrated comparable results. Radiographic measurements showed a significant reduction in the AC distance and CC distance after surgery in all subgroups. The early complication rate was 9.5% for all patients, while late complications occurred in 14.3% of all cases. Compared to the established methods, the operative TightRope(®) procedures represent a safe alternative in Rockwood III injuries. All investigated techniques predominantly led to good and excellent clinical results in acute Rockwood type III AC joint instabilities. Avoidance of material removal and shorter hospital stays appear to speak in favour for the TightRope(®) technique. IV. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Introduction In extra-articular distal radius fractures closed reduction and casting has been the mainstay of treatment, difficulty lies in predicting and maintaining the proper reduction at final union. Percutaneous K-wire stabilization is also a widely accepted treatment option, but there is no consensus on its outcome in comparison to closed reduction and casting. Aim To evaluate the results of closed reduction and casting versus closed reduction with percutaneous K wire fixation and casting in the treatment of the distal radius extra-articular fracture with reference to the restoration of radial height, radial inclination, volar tilt of the distal articular surface and to assess the functional outcome of the same measured by the Gartland and Werley demerit scoring system. Materials and Methods Prospective study was conducted on 60 patients attending the Department of Orthopaedics, from December 2013 to May 2015 with extra-articular fractures (AO type 23-A2 and 23-A3) of distal radius and fulfilling all the inclusion and exclusion criteria. The cases were randomly divided into two equal groups of 30 patients, the first group treated by closed reduction and below elbow cast application, while the second group were treated by closed reduction percutaneous K-wire application and below elbow cast application. The radiological outcome of both groups were evaluated by measuring the Volar inclination, Radial inclination and Radial height, while the functional outcome was evaluated by the demerit scoring system of Gartland and Werley. Results The Cast application group had 13 excellent, 9 good, 7 fair and 1 poor result the mean outcome score of the group was 5.2. The K wiring group had 11 excellent, 13 good, 5 fair and 1 poor result, the mean score of the group was 5.17. The unpaired student’s t-test on the values obtained from both groups yielded a p-value of 0.9816. The mean radial height in the Cast application group was 8.033mm while the mean in the k wiring group

    The transmaxillary K-wire is a simple, fast, safe, and effective technique for the fixation of unstable tractured malar bones. Combined with other techniques such as interdental fixation it simplifies and provides the fixation of the Le Fort II fracture or osteotomy and certain osteotomies used for facial advancement. The technique of insertion is described and illustrated. Images Fig. 4 Fig. 5 Fig. 6 PMID:666241

    Recurrence rates for toe deformity correction are high and primarily are attributable to scar contractures. These contractures may result from subclinical infection. We hypothesized that (1) recurrence of toe deformities and residual pain are related to low-grade infections from biofilm formation on percutaneous K wires, (2) biofilm formation is lower on titanium (Ti) K wires compared with stainless steel (SS) K wires, and (3) clinical outcome is superior with the use of Ti K wires compared with SS K wires. In this prospective nonrandomized, comparative study, we investigated 135 lesser toe deformities (61 patients; 49 women; mean ± SD age, 60 ± 15 years) temporarily fixed with K wires between August 2010 and March 2011 (81 SS, 54 Ti). K wires were removed after 6 weeks. The presence of biofilm-related infections was analyzed by sonication. High bacterial loads (> 500 colony-forming units [CFU]/mL) were detected on all six toes requiring revision before 6 months. Increased bacterial load was associated with pain and swelling but not recurrence of the deformity. More SS K wires had greater than 100 CFU/mL bacteria than Ti K wires. For K wires with a bacterial count greater than 100 CFU/mL, toes with Ti K wires had a lower recurrence rate, less pain, and less swelling than toes with SS K wires. Ti K wires showed superior clinical outcomes to SS K wires. This appears to be attributable to reduced infection rates. Although additional study is needed, we currently recommend the use of Ti K wires for the transfixation of toe deformities. Level II, therapeutic study.

    Modified, reversal technique of fixation in digital replantation using K-wires was analyzed. The results obtained from the standard technique and reversal technique of fixation using K-wires were compared. The aim was to compare the results of osteofixation using K-wires in digital replantation when either standard or reversal, modified technique was used. A retrospective study included 103 replanted fingers in 72 patients. The first group included standard fixation using K-wires and the second group included fixation using K-wires, but with a modified technique. Modification consisted of the opposite order of moves during the phalanges fixation compared to the standard technique: first, K-wire was introduced intramedullary in the proximal phalanx and the top of the wire was drawn out through the skin in proximal part of the finger or hand. Second, distal part of the wire was introduced in the phalanx of the amputated part of the finger intramedullary until the wire entered the cortex. Duration of bone healing after digital replantation was shorter in cases where reversal technique was used in comparison with standard technique (7.2 weeks compared to 7.5 weeks). The comparison of standard and reversal technique of phalangeal fixation with K-wires in digital replantation shows that both techniques are useful. Reversal technique expands the choice of operative techniques for bone fixation during the replantation. It shows some advantages and enables avoidance of vein injuries.

    Acromioclavicular (AC) joint dislocations usually occur in a young active population as a result of a fall on the shoulder. Rockwood divided these dislocations into six types. Optimal treatment is still a matter of discussion. Many operative techniques have been developed, but the main choice is between open and minimally-invasive arthroscopic procedures. The aim of this study was to compare two different surgical methods on two groups of patients to find out which method is superior in terms of benefit to the patient. The methods were evaluated through objective and subjective scores, with a focus on complications and material costs. A retrospective two-centre study was conducted in patients with acute AC joint dislocation Rockwood types III and V. The two methods conducted were an open procedure using K-wires combined with FiberTape(®) (Arthrex, Naples, USA) (Group 1) and an arthroscopic procedure using the TightRope System(®) (Arthrex, Naples, USA) (Group 2). Groups underwent procedures during a two-year period. Diagnosis was based on the clinical and radiographic examination of both AC joints. Surgical treatment and rehabilitation were performed. Sixteen patients were included in this study: Group 1 comprised 10 patients, all male, average age 41.6 years (range 17-64 years), Rockwood type III (eight patients) and Rockwood type V (two patients); Group 2 had six patients, one female and five male, average age 37.8 years (range 18-58 years), Rockwood type III (two patients) and Rockwood type V (four patients). Time from injury to surgery was shorter and patients needed less time to return to daily activities in Group 1. Duration of the surgical procedure was shorter in Group 2 compared with Group 1. Complications of each method were noted. According to the measured scores and operative outcome between dislocation Rockwood type III and V, no significant difference was found. Implant material used in Group 2 was 4.7 times more expensive than that used in Group 1

    To compare K-wire and screw fixation of distal phalanx (DP) fractures with respect to union and functional outcome. This retrospective study identified patients with DP fractures from a clinic registry taken from 2007 to 2013. Clinical data collected included patient demographics, range of motion (ROM), removal of implant (ROI), and complications. Radiographic data collected included fracture type, location, configuration, fracture displacement, and radiographic union. Statistical analysis was done using a chi-squared test for categorical variables and paired Student's t test for continuous variables. A total of 172 patients with DP fractures were seen in our clinic between 2007 and 2013. Of these, 141 patients were managed conservatively and 31 patients had surgery for 33 DP fractures, of which 12 had K-wire and 21 had screw fixation. Mean union incidence for screw was 100% compared with 83% for K-wire. Time to union was 2.4 months for screw fixation compared with 4.1 months for K-wire fixation. ROM for screw fixation was significantly better (60°) compared with K-wire fixation (45°). ROM for non-transarticular K-wire (46°) was similar to transarticular K-wire (44°). ROI was performed in 52% of patients with screw fixation. Other than fingertip tenderness, which resolved after ROI, no other complications were noted. Our study showed that the union incidence and time to union for screw fixation were comparable to those for K-wire fixation. Screw fixation of DP fractures resulted in greater distal interphalangeal joint motion compared with K-wire fixation but required removal in half of cases. Therapeutic III.

    Traditional pull-out techniques for tendon and ligament repair are still widely used in hand surgery, despite constant refinements and the development of other methods of fixation. We propose a modification of the classic technique which utilizes a K-wire as an external strut instead of the classic button. This fixation system can be usefully applied in the fixation of extensor and flexor tendons and reinsertions. It is particularly applicable in situations where a transarticular K-wire is to be used anyway, in situations of temporary joint immobilization and in other situations.

    The aim of this study was to compare the outcomes between Kirschner wire (K-wire) splinting and intranasal packing. The authors performed a retrospective and comparative analysis of subjective patient discomfort and objective postoperative computed tomography (CT) imaging after closed reduction for treating type II and type III nasal bone fractures from April 2010 to April 2013 in 2 groups, 1 with K-wire splinting and 1 with intranasal packing. Complaints of nasal obstruction, dry mouth, loss of appetite, and sleep disturbance were significantly less in K-wire group. Mean scores for concerns about aesthetics/postoperative asymmetry did not differ significantly between groups. There was no significant difference in accuracy of reduction and support provided to the reduced nasal bones between groups. The K-wire fixation can be considered a reliable and useful immobilization method for treating type II and type III nasal bone fractures.

    PubMed

    De Spirito, Daniele

    2013-09-01

    Closed percutaneous wire fixation of hand fractures frequently requires protection with external splintage. This splintage increases the risk of joint stiffness, prolongs recovery time, and increases therapy input. We have developed a method of linking external Kirschner wires (K-wires), using a metal clamp, after their insertion, so as to increase the security of fixation and facilitate postoperative mobilization. The mechanical properties of this method have been assessed in vitro and compared with conventionally fixed, unlinked, K-wires. We have been able to establish that the linked K-wire system is better able to resist loosening. This work proposes that linkage of K-wires permits omission of all additional external splintage, with no detriment to management. The technique has been applied in clinical cases over the past 8 years and results of treatments were evaluated mainly to detect unexpected complications. We report a low rate of complications and good results in terms of bone healing and recovery of function.

    To compare the use of crossed K-wire and prebent intramedullary nail techniques for the fixation of distal radius metaphyseal fracture in children. Intraoperative and follow-up data for children with distal radius metaphyseal fracture, treated using crossed K-wire or prebent intramedullary nail fixation, were retrospectively analysed. Patient groups were matched for age, sex and clinical parameters (fracture location, affected side, fracture type). Patients treated using prebent intramedullary nail fixation (n = 52) had significantly shorter surgery duration, fewer intraoperative X-radiographs, and lower prevalence of postoperative redisplacement and malalignment deformity than those treated using crossed K-wire fixation (n = 52). Both techniques resulted in similar postoperative complications and recovery of forearm rotation. Prebent intramedullary nail fixation has a better functional outcome than crossed K-wire fixation in the treatment of distal radial epiphyseal fracture in children. © The Author(s) 2015.

    Laboratory tests were carried out on cadaver animal bones to evaluate the thermal effect of inserting K-wires with a pneumatic hammer as compared to drilling. The mean maximum bone temperature 0.5 mm from the K-wires was 34 (22-72) degrees C using the hammer and 54 (19-100) degrees C for drilling, 1.0 mm from the K-wire the mean maximum temperature was 31 (19-52) degrees C for hammering and 47 (17-91) degrees C for drilling. The mean time for the temperature exposure in the cases of drilling was 50 s and for hammering 41 s. The hammering device may reduce the risk of heat-induced injury.

    Good outcomes have been described for pediatric lateral condyle fractures treated by open reduction and fixation using either screws or Kirschner wires (K-wires). No studies have compared the biomechanical properties of the 2 fixation methods. We hypothesized that screw fixation would be more biomechanically stable than K-wire fixation. Synthetic humerus models were used for biomechanical testing, following a previously published protocol. A miter saw was used to make an oblique cut to simulate a Milch type II fracture. Fractures were anatomically reduced and fixed with either 2 divergent 0.062-inch K-wires placed bicortically or a 4.0-mm lag screw placed obliquely (perpendicular to the fracture line). Specimens were then embedded in polymethyl methacrylate bone cement for testing. Mechanical testing using displacement control was performed applying compression or distraction from 0 to 1.5 mm at a rate of 0.5 mm/s for 10 cycles. The maximum force was calculated based on the maximum force averaged over the 10 cycles. Stiffness was calculated based on the slope of the force-displacement curve of the 10th cycle. A 2-sample t test was used to determine significant differences between the stiffness and maximum force comparing the K-wire and screw groups. A P-value of <0.05 was considered statistically significant. Stiffness and maximum force in tension testing were significantly greater with screw fixation compared with K-wire fixation. Testing in compression revealed statistically significant increased maximum force and a trend towards increased stiffness. Screw fixation in a synthetic bone model of pediatric lateral condyle fractures (Milch type II) provides increased biomechanical stability of the construct as compared with K-wires. If similar effects were seen in vivo, increased biomechanical stability with screw fixation could decrease the occurrence of complications such as loss of reduction and nonunion.

    2017-07-01

    The Kirschner wire (K-wire) is a common bone drilling tool in orthopedic surgery to affix fractured bone. Significant heat is produced due to both the cutting and the friction between the K-wire and the bone debris during drilling. Such heat can result in high temperatures, leading to osteonecrosis and other secondary injuries. To reduce thermal injury and other high-temperature associated complications, a new K-wire design with three notches along the three-plane trocar tip fabricated using a thin micro-saw tool is studied. These notches evacuate bone debris and reduce the clogging and heat generation during bone drilling. A set of four K-wires, one without notches and three notched, with depths of 0.5, 0.75, and 1mm, are evaluated. Bone drilling experiments conducted on bovine cortical bone show that notched K-wires could effectively decrease the temperature, thrust force, and torque during bone drilling. K-wires with notches 1mm deep reduced the thrust force and torque by approximately 30%, reduced peak temperatures by 43%, and eliminated blackened burn marks in bone. This study demonstrates that a simple modification of the tip of K-wires can effectively reduce bone temperatures during drilling. Copyright © 2017 IPEM. Published by Elsevier Ltd.

    Acromioclavicular dislocations are very common shoulder injuries. The optimal treatment for acute high-grade acromioclavicular joint injury remains a matter of debate. The purpose of this study was to evaluate the results of surgical treatment of complete acromioclavicular dislocation using coracoid process transfer and temporary K-wire transfixation. Twenty-one patients with complete acromioclavicular dislocation underwent coracoid process transfer and temporary K-wire transfixation. Patients were assessed at the follow-up based on visual analog scores (VAS), the Constant-Murley scoring system and the UCLA shoulder rating system. Radiographs were taken to check up vertical instability. The mean follow-up was 32.1 months (25-47 months). The mean Constant and Murley score and UCLA shoulder rating score was 89.9 ± 8.4 and 30.1 ± 4.4. There were fourteen excellent functional results and six results and one poor result. The overall rate of satisfaction, which means an excellent or good result, was 95.2 %. Nineteen patients (90.4 %) maintained their previous jobs or resume their daily activities. The mean final pain score, as measured from 1 to 10 on the visual analog scale, was 1.91 ± 1.09. The radiographic analysis revealed twenty patients had maintained reduction at the final follow-up. The coracoid process transfer and temporary K-wire transfixation is a reliable treatment for a complete acromioclavicular dislocation.

    After osteosynthesis of the proximal humerus by Kirschner wires (K-wire), loosening and secondary loss can occur. This study tested primary fixation of wires made from a shape memory alloy (SMA) Nitinol (NiTi), compared to conventional steel K-wires by pull-out tests. Blocks of cancellous bone were tested with three wire types: NiTi-K-wire with split apex geometry and conventional steel K-wires with and without threads. We found that NiTi-wires can be pulled out of bone more easily than steel wires (P=0.05), even though the former had rougher surfaces. The application of NiTi-wires through bone produced no better stability in comparison to normal steel K-wires, because of triggering the memory effect. Further studies are required to determine if NiTi wires of another appropriate design, surface and localization are superior to conventional wires in the context of this application.

    Tension-band wiring (TBW) has been accepted as the treatment of choice for displaced olecranon fractures. The aim of this study was to examine the effect of K-wire position on instability of the K-wires in relation to local complications and radiological and clinical long-term outcome. We reviewed the early follow-up of 59 patients (mean age, 60 years) who underwent TBW osteosynthesis for displaced olecranon fractures. Follow-up information was available from medical records and radiographs. The main outcome measurements were proximal migration of the wires, gap, step, range of motion, and complications. Long-term follow-up included 21 patients (mean age, 58 years). Follow-up was available from a clinical visit and a radiograph. Visual Analogue Scale (VAS), Mayo Elbow Performance Score (MEPS), Disabilities of the Arm Shoulder and Hand (DASH), EuroQol-5D (EQ-5D), and Broberg and Morrey osteoarthritis scores were obtained. Seventy-eight percent of the patients treated with intramedullary K-wires were found to have instability of K-wires, compared to 36% in the patients treated with transcortical K-wires. Patients with instability of the K-wires tend to develop osteoarthritis more often. There is a better functional outcome in patients where the osteosynthetic material is removed. Instability of K-wires after TBW is more common after intramedullary placement of the wires resulting in proximal migration of the K-wires and gap appearance. There was a tendency of more osteoarthritis in the group of patients where instability of K-wires was identified. We would recommend the use of transcortical placed wires, as well as to have a low threshold in removing the implants. Crown Copyright © 2012. Published by Mosby, Inc. All rights reserved.

    K-wire fixation has been the most common method of fixation for hammertoe deformity. However intramedullary devices are gaining ground in both number of available choices and in procedures performed. This study aimed to compare the outcomes of hammertoe correction performed with K-wire fixation versus a novel intramedullary fusion device (CannuLink). A retrospective review of hammertoe correction by a single surgeon was performed from June 2011 to December 2013. Sixty patients (95 toes) underwent K-wire fixation and 39 patients (54 toes) underwent fusion with the CannuLink implant. Average age was 61.7 years and 61.4 years, respectively. Average length of follow-up was 12.9 and 12.3 months, respectively. Patients were evaluated for medical comorbidities, smoking status, inflammatory arthritis, peripheral vascular disease, peripheral neuropathy, pre- and postoperative visual analog pain scale, bony union percentage, revision rate, complications (hardware and surgery-related), and persistent symptoms at last follow-up. There was no significant difference in demographics or comorbidities between the 2 groups ( P > .05). In the K-wire group, 16 patients (18 toes) remained symptomatic at last follow-up (27%). Nine toes (9.5%) had recurrent deformity, 3 toes (3%) developed a late infection because of the recurrent deformity, and 1 toe (1%) developed partial numbness. One patient suffered a calf deep vein thrombosis (DVT) and peroneal nerve neuritis, 1 patient developed foot drop, and 3 patients continued to complain of pain. Five toes required revision surgery (5.3%). In the intramedullary group, 3 (7.7%) patients remained symptomatic and all were associated with a complication. One patient developed chronic regional pain syndrome in the foot, a calf DVT, and a nonfatal pulmonary embolus. A second patient developed a painless recurrent deformity. A third patient had wound dehiscence. Nobody had hardware failure or required a second operation. The CannuLink intramedullary

    INTRODUCTION Kirschner wires (K-wires) are immensely versatile in fracture fixation in the paediatric population. Complications associated with the K-wiring procedure vary from minor to a life-threatening. The aim of this study was to analyse the outcome of fracture fixation using K-wires in all types of upper-extremity fractures in children in order to assess the incidence and type of complication critically. PATIENTS AND METHODS Between September 1999 and September 2001, we retrospectively reviewed a consecutive series of 105 fractures in 103 paediatric trauma cases (below 12 years) treated with K-wires in a university teaching hospital. The case notes and radiographs were reviewed by an independent single assessor. All paediatric, acute, upper-extremity, displaced and unstable fractures were included. All elective procedures using K-wires were excluded. RESULTS We observed an overall 32.3% complication rate associated with the K-wiring procedure affecting 34 pins (24 patients). Wound-related complications included over-granulation in 13 cases, pin tract infection in 6 cases and hypersensitive scar in 1 case. Neurapraxia was found in 3 patients and axonotmesis in 1 patient. Wire loosening at the time of removal in 14 cases and retrograde wire migration in 4 cases were observed. There were 2 cases of penetrating tendonitis and 1 case of osteomyelitis. There was a higher complication rate in terms of wire loosening and pin tract infection when the K-wires: (i) were left outside the skin compared with those placed under the skin; (ii) stayed longer in the patients; and (iii) did not traverse both cortices. There were more complications in complex operations performed by senior surgeons (P = 0.056). The duration of K-wire stay, associated co-morbidity and anatomical location were statistically insignificant. CONCLUSIONS Complications are part of operative procedures; an important point to consider is what causes them in order to take preventative measures. We

    Supracondylar fractures of the humerus occur frequently in children and account for approximately 70% of all elbow fractures. The aim of this systematic review is to critically appraise randomized controlled trials in the literature comparing the outcome of surgical treatment of extension type Gartland III supracondylar fractures using either a cross pin configuration or lateral pins only for fixation in terms of the stability of fixation and the incidence of encountered complications. Only 4 randomized trials were found over the past 10 years. These were reviewed according to the CONSORT 2010 check list. No study found any significant statistical difference in terms of loss of reduction between the two groups, suggesting similar stability of both constructs. There is currently, however, no Level 1 evidence comparing the outcome of crossed pinning versus lateral entry pinning in extension type Gartland III supracondylar fracture. Additionally, the current highest level evidence discussed above has limitations ranging from small sample size to insufficient data on clinical outcome. Therefore we cannot draw any firm conclusions on the above evidence. We suggest that future RCTs take into account the recent evidence on fixation by including three lateral pins and larger diameter pins in their cohorts.

    Supracondylar humeral fractures (SCHF) are among the most common injuries in children. The aim of this systematic review was to investigate functional and radiographic outcome after crossed and lateral K-wire fixation for displaced extension-type SCHF, and complications related to the type of K-wire construction used. RCTs and prospective comparative cohorts on the functional outcome and complications after fracture reduction and K-wire fixation were identified in MEDLINE, Embase, Web of Science and the Cochrane Library. Thirteen studies were identified, including 1158 patients in seven RCTs and six prospective comparative cohorts. According to the Flynn criteria, there was no difference in outcome between the K-wire configurations (Relative Risk 1.07). Loss of reduction occurred in 27 (11.6%) of 232 patients treated with crossed K-wires, and in 35 (12.4%) of 282 patients treated with lateral entry K-wires. Twenty (4.1%) of 493 patients in the crossed group were diagnosed with iatrogenic ulnar nerve injury, compared with 2 (0.3%) of 666 patients in the lateral entry group. The overall incidence of persistent ulnar nerve related complaints was 3.5/1000. Crossed and lateral entry pin fixation of SCHF result in similar construct stability and functional outcome. Although ulnar nerve injury was three times more likely in the crossed K-wire group, the overall incidence of this complication was very low. The available evidence does not support the use of either approach for daily practice. If the surgeon wishes to avoid all potential risk of iatrogenic ulnar nerve injury, the lateral K-wire approach is safest. Copyright © 2016 Elsevier Ltd. All rights reserved.

  3. Temporary vs. Permanent Sub-slab Ports: A Comparative ...

    EPA Pesticide Factsheets

    Vapor intrusion (VI) is the migration of subsurface vapors, including radon and volatile organic compounds (VOCs), from the subsurface to indoor air. The VI exposure pathway extends from the contaminant source, which can be impacted soil, non-aqueous phase liquid, or contaminated groundwater, to indoor air-exposure points. Therefore, contaminated matrices may include groundwater, soil, soil gas, and indoor air. VOC contaminants of concern typically include halogenated solvents such as trichloroethene, tetrachloroethene, and chloroform, as well as petroleum hydrocarbons, such as the aromatic VOCs benzene, toluene, and xylenes. Radon is a colorless radioactive gas that is released by radioactive decay of radionuclides in rock and soil that migrate into homes through VI in a similar fashion to VOCs. This project focused on the performance of permanent versus temporary sub-slab sampling ports for the determination of VI of halogenated VOCs and radon into an unoccupied house. VOC and radon concentrations measured simultaneously in soil gas using collocated temporary and permanent ports appeared to be independent of the type of port. The variability between collocated temporary and permanent ports was much less than the spatial variability between different locations within a single residential duplex. The agreement of the majority of VOC and radon concentrations, 0–36% relative percent difference, and 2–19% relative standard deviation respectively, of each sub-sl

    Scaphoid nonunion can occur in both non-operative and operatively treated scaphoid fractures. Without treatment, this can lead to a predictable pattern of carpal collapse and degenerative arthritic change and patients can experience both pain and functional loss in the early and late phases of progression. An operative technique with a high success rate for union is important. This paper describes a technique for treatment of scaphoid nonunion with K-wire fixation and iliac crest cancellous bone graft. A retrospective review from 1996 to 2010 was performed on a single senior surgeon's private university-based practice. Patient demographic information and fracture characteristics were obtained to evaluate for influence on success and time to union. There were 32 patients identified for inclusion in this study. Union was achieved in 100% of the patients, including 44% that had proximal pole fractures. The median time from injury to surgery was 41.86 weeks. The median time from surgery to healing was 17.93 weeks. Time to union was not affected by patient age, fracture location, smoking, alcohol use, or time to treatment. K-wire fixation and ICBG for treatment of scaphoid nonunion using our technique have equal or superior union rates compared to other techniques in the literature. This paper highlights the keys to success using this method. Therapeutic Level IV.

    To determine the relative importance of intramedullary wire (IMW) diameter and IMW number in conferring stability to a metacarpal fracture fixation construct. Our research hypothesis was that the stiffness of IMW fixation for metacarpal shaft fractures using a single 1.6-mm-diameter (0.062-in) wire would be greater than three 0.8-mm-diameter (0.031-in) wires. Our study compared the biomechanical stiffness between one 1.6-mm K-wire and three 0.8-mm K-wires in a composite, fourth-generation, biomechanical metacarpal construct under cantilever testing to treat transverse metacarpal shaft fractures. Six composite bone-wire constructs were tested in each group using constant-rate, nondestructive testing. Stiffness (load/displacement) was measured for each construct. All constructs demonstrated a linear load-displacement relationship. Wires were all tested in their elastic zone. The mean stiffness of the 1-wire construct was 3.20 N/mm and the mean stiffness of the 3-wire construct was 0.76 N/mm. These differences were statistically significant with a large effect size. The stiffness of IMW fixation for metacarpal shaft fractures using a single 1.6-mm-diameter wire was significantly greater than using three 0.8-mm-diameter wires. When IMW fixation is clinically indicated for the treatment of metacarpal fractures, the increased stiffness of a single large-diameter construct provides more stability in the plane of finger flexion-extension.

    In many orthopedic surgeries, there is a demand for correctly placing medical instruments (e.g., K-wire or drill) to perform bone fracture repairs. The main challenge is the mental alignment of X-ray images acquired using a C-arm, the medical instruments, and the patient, which dramatically increases in complexity during pelvic surgeries. Current solutions include the continuous acquisition of many intra-operative X-ray images from various views, which will result in high radiation exposure, long surgical durations, and significant effort and frustration for the surgical staff. This work conducts a preclinical usability study to test and evaluate mixed reality visualization techniques using intra-operative X-ray, optical, and RGBD imaging to augment the surgeon's view to assist accurate placement of tools. We design and perform a usability study to compare the performance of surgeons and their task load using three different mixed reality systems during K-wire placements. The three systems are interventional X-ray imaging, X-ray augmentation on 2D video, and 3D surface reconstruction augmented by digitally reconstructed radiographs and live tool visualization. The evaluation criteria include duration, number of X-ray images acquired, placement accuracy, and the surgical task load, which are observed during 21 clinically relevant interventions performed by surgeons on phantoms. Finally, we test for statistically significant improvements and show that the mixed reality visualization leads to a significantly improved efficiency. The 3D visualization of patient, tool, and DRR shows clear advantages over the conventional X-ray imaging and provides intuitive feedback to place the medical tools correctly and efficiently.

    Distal radius fractures represent about one-sixth of all fractures. There is still no consensus on the treatment of this fracture. We have several issues to assess and address; one of them is the fixation method. We tried to compare the effectiveness of two methods of stabilisation of distal radial fracture. Comparison between the techniques of Kirschner wire (K-wire) fixation with plaster and K-wire fixation with external fixation (Ex-Fix) was undertaken to assess which treatment modality gives better results in patients with distal radius fracture Frykman VII and VIII with no metaphyseal comminution. Fifty-six patients were chosen randomly and then allocated to two different modalities of stabilisation randomly as well, they were followed up; three of them were lost to follow-up because of death and two moved away from the area. Fifty-one patients were randomised in two groups: 24 were treated with K-wire and spanning Ex-Fix supplementation and 27 were treated with K-wires and plaster. Patients were prospectively monitored following the operation with a minimum follow-up of 1 year. Measurement of range of motion was obtained after surgery. Visual Analogue Scale (VAS) scores for pain and satisfaction levels were also recorded. There was statistically significant difference in favour of the Ex-Fix patient group for pain (VAS, Ex-Fix group: mean 14.9; plaster group: mean 28.1) and satisfaction (Ex-Fix group: mean 89.7;plaster group: mean 76.3). Although one would expect that range of motion would be reduced in the Ex-Fix group, there were no statistically significant differences found, with the exception of supination where results were in favour of the Ex-Fix group (mean 54.4; plaster group: mean 45.2). In our study, xternal fixator (Ex-Fix) supplementation of K-wiring favoured patients with distal radius fracture, even though there was no metaphyseal comminution, and therefore is suggested in contrast to plaster supplementation. © Article author(s) (or their

    Kirschner wire characteristics affect the heating of bone during insertion and the subsequent strength of fixation. We inserted 90 sharp and 90 obtuse trocar-tip K-wires into 90 fresh frozen human cadaver metacarpals using either a drill or a pneumatic hammer. The temperature elevation, insertion time and extraction force were measured for four K-wire insertion combinations: drilling sharp; drilling obtuse; hammering sharp; hammering obtuse. Hammering resulted in significantly lower temperature elevations than drilling. Hammering sharp K-wires resulted in the highest extraction forces. The first and fifth metacarpals showed significantly lower temperature elevations than the other metacarpals, while the insertion time was significantly higher in the second and third metacarpal than in the other metacarpals. Hammering sharp trocar-tip K-wires minimises thermal damage to bone and gives the strongest fixation.

    Different methods exist to treat distal radius fractures. A prospective randomized study was conducted to establish whether palmar plate fixation with locking screws gave better results than percutaneous K-wire fixation in patients over 50 years of age. Only fractures with dorsal displacement after a simple fall were included in the study. Twenty wrists were treated with K-wires and 20 with a plate. Radiological parameters were measured on preoperative radiographs and at five weeks postoperatively. Clinical results and DASH scores were determined at three months postoperatively and at more than one year. No significant difference in radial inclination, palmar tilt, clinical outcome and DASH score was found between plating and K-wires, but the mean difference in ulnar variance between pre- and postoperative radiographs was significantly better with plates. It can be concluded that plates were superior to K-wires in restoring ulnar variance, but functional outcome was similar with both techniques.

There were no differences in radiographic outcomes (volar tilt, radial inclination, and radial height) between the two interventions. Superficial wound infection was more common in patients treated with K-wires (8.2% versus 3.2%; RR = 2.6; p = 0.001), but otherwise no difference in complication rates was found. Despite the small number of studies and the limitations inherent in a meta-analysis, we found that volar locking plates show better DASH scores at 3- and 12-month followups compared with K-wires for displaced distal radius fractures in adults; however, these differences were small and unlikely to be clinically important. Further research is required to better delineate if there are specific radiographic, injury, or patient characteristics that may benefit from volar locking plates in the short term and whether there are any differences in long-term outcomes and complications.

    2012-01-01

    INTRODUCTION Lateral humeral condyle fractures typically require a longer period of internal fixation than other distal humeral fractures due to the increased risk of non-union. K-wires can be buried and left in situ until union or they can be left unburied and require removal after four weeks, with plaster immobilisation until union. There is no consensus as to whether wire burial is preferable or not. The aim of this study was to determine whether K-wire burial is associated with more complications than non-buried wires in treating lateral condyle fractures of the elbow. METHODS All patients with lateral humeral condyle fractures treated with K-wire fixation at our institution from May 2008 to August 2011 were included in the study. Fracture configuration, mode of reduction, wire burial and complications were assessed. RESULTS Sixty-seven patients (19 girls and 48 boys, mean age: 6.5 years, range: 1–17 years) were included in the study. All had closed injuries and were treated with open reduction and K-wire fixation. K-wires were buried in 55 patients. Thirteen cases of buried wires eroded through skin and were removed on average 45 days (range: 30–58 days) post-operatively. Of the wire erosion cases, three developed microbiologically proven infections, one of which was a deep infection. There were a further three superficial wound infections in the absence of wire erosion through the skin. There were complications in 2 of the 12 cases in the unburied wires group: 1 microbiologically proven superficial wire site infection and 1 wire backed out after 11 days, requiring refixation. CONCLUSIONS Wire erosion through the skin is the most common complication of K-wire burial. This may be due to the decrease in swelling after fracture fixation, making the wires more prominent under the skin. Skin integrity should be monitored closely if wires are buried. PMID:23031772

    Pelvic Kirschner wire (K-wire) insertion is a challenging surgical task requiring interpretation of complex 3D anatomical shape from 2D projections (fluoroscopy) and delivery of device trajectories within fairly narrow bone corridors in proximity to adjacent nerves and vessels. Over long trajectories ( 10-25 cm), K-wires tend to curve (deform), making conventional rigid navigation inaccurate at the tip location. A system is presented that provides accurate 3D localization and guidance of rigid or deformable surgical devices ("components" - e.g., K-wires) based on 3D-2D registration. The patient is registered to a preoperative CT image by virtually projecting digitally reconstructed radiographs (DRRs) and matching to two or more intraoperative x-ray projections. The K-wire is localized using an analogous procedure matching DRRs of a deformably parametrized model for the device component (deformable known-component registration, or dKC-Reg). A cadaver study was performed in which a K-wire trajectory was delivered in the pelvis. The system demonstrated target registration error (TRE) of 2.1 ± 0.3 mm in location of the K-wire tip (median ± interquartile range, IQR) and 0.8 ± 1.4º in orientation at the tip (median ± IQR), providing functionality analogous to surgical tracking / navigation using imaging systems already in the surgical arsenal without reliance on a surgical tracker. The method offers quantitative 3D guidance using images (e.g., inlet / outlet views) already acquired in the standard of care, potentially extending the advantages of navigation to broader utilization in trauma surgery to improve surgical precision and safety.

    Closed reduction and K-wire fixation is standard treatment for displaced supracondylar fractures in children. The purpose of this study is to evaluate pain using 2 pediatric pain scales when removing K-wires from the distal humerus in children in the office setting. A total of 98 percutaneous smooth K-wires were removed from 47 patients who had sustained displaced supracondylar fractures of the elbow. Pain was measured using the Children's Hospital of Eastern Ontario Pain Scale (CHEOPS). The maximum score is 13 and the minimum score is 4 points. In addition, after K-wire removal, each child indicated on a numbered pain-face diagram (Wong-Baker FACES: a scale consisting of faces with varying emotional expressions and corresponding numbers on a scale from 0 to 5) the amount of pain that they felt. The average age of the patients treated was 7.1 years (range, 2 to 14 y). There were 28 males and 19 females. Thirty patients (64%) had a CHEOPS score of ≤6. The average CHEOPS was 6 (range, 4 to 10). Seventeen patients (37%) had a FACES score of ≤1. The average FACES score was 2 (range, 1 to 5). Higher CHEOPS and FACES scores correlated with younger patient age and higher number of K-wires removed. K-wire removal in the clinic is common practice. The pain associated with K-wire removal and the safety of this practice has received minimal previous study in the literature. In the present manuscript, 64% of patients had little or no pain measured by the CHEOPS scale--score of ≤6 and 36% had little or no pain self-reported by the FACES scale--score of ≤1. No patient reported severe pain by the CHEOPS scores (CHEOPS 11 to 13) and only 1 patient reported having severe pain with a FACES of 5. No complications occurred. The results of this study suggest that the removal of K-wires in the office setting is safe and acceptable. Retrospective analysis.

    Closed reduction and percutaneous pinning is a reliable technique for treating 2- and 3-part distal radius fractures. There are currently no data that demonstrate the proximity of at-risk nerves and tendons during percutaneous placement of 5 commonly used K-wires. Whereas the previous literature notes the risk of superficial radial nerve injury with K-wire insertion into the radial styloid, the current study provides specific distances, not only to the superficial radial nerve (SRN) but also to the tendons of the first through fifth extensor compartments during K-wire insertion. K-wires (1.5 mm or 0.059 in) were placed percutaneously into the distal radius of 15 cadaver specimens, simulating fixation of a distal radius fracture. After dissection, the distance from the K-wires to the extensor tendons and branches of the SRN were measured and tabulated. The volar radial styloid K-wire was an average distance of 1.47 mm +/- 1.7 from the closest branch of the SRN. One penetrated a branch of the SRN. The dorsal radial styloid K-wire was an average distance of 0.35 mm +/- 0.64 from the closest branch of the SRN. No tendons in the first compartment were found penetrated by or touching the K-wires. The transverse radial K-wire was an average distance of 1.07 mm +/- 1.57 from the branches or trunk of the SRN. One K-wire was found piercing the volar branch of the SRN, and 1 K-wire was found piercing the abductor pollicis longus. The dorsal rim K-wire was an average of 2.94 mm +/- 2.11 from the ulnar aspect of the extensor pollicis longus and an average of 1.44 mm +/- 1.65 from the radial aspect of the extensor digitorum communis. The dorsoulnar K-wire was an average distance of 1.88 mm +/- 1.6 ulnar or radial to the extensor digiti quinti proprius and penetrated it in three specimens. The volar radial styloid, transverse radial, and dorsoulnar K-wires all penetrated either tendons or nerves. It is therefore prudent to make a small incision to identify and protect the

    To summarize application of rafting K-wires technique for tibial plateau fractures. From January 2013 to January 2015,45 patients with tibial plateau fractures were treated by locking plate with rafting K-wires, including 33 males and 12 females with an average of 44.2 years old ranging from 22 to 56 years old. According to Schatzker classification, 6 cases were type II, 8 were type Ill, 4 were type IV, 4 were type V, and 5 were type VI. Allogeneic bone graft were performed for bone defects. All patients were fixed with two to five K-wires. Part of weight loading were encouraged at 3 months after operation,and full weight-loading were done at 5 months after operation. Postoperative complications were observed,and Rasmussen clinical and radiological assessment were used to evaluate clinical results. All Patients were followed up from 10 to 23 months with average of 14 months. According to Rasmussen clinical and radiological assessment, clinical scores 23.58 ± 6.33, radiological scores were 14.00 ± 6.33; and excellent and good rates were 82.2% and 77.8% respectively. Four patients occurred severe osteoporosis and collapse of articular surface; 5 patients occurred traumatic arthritis. Rafting K-wires technique with anatomized armor plate could effective fix and support platform collapse and joint bone fragments, increase support surface area and reduce postoperative reduction loss rate.

  17. Does K-wire position in tension band wiring of olecranon fractures affect its complications and removal of metal rate?

    2015-01-01

    Background Despite the recognised complications of migration of wires and soft tissue irritation, tension band wiring (TBW) remains the gold standard for fixation of displaced, minimally comminuted olecranon fractures. There is much variation in placement of the K-wires with current AO guidance stating that each wire should be drilled through the anterior cortex and then backed up by 1 cm. The aim of this study was to examine the effect of K-wire position (intramedullary vs. transcortical) on stability of the construct and significant local complications. Methods All patients who underwent TBW for an isolated olecranon fracture in our trauma unit between 1/1/2009 and 31/12/2011 were included in this retrospective study. Mean follow-up was 14 months (range 5–29 months). Data was gathered from medical records and radiographs. The outcome measured was removal of metal due to complications such as wound problems or proximal migration of wires as standard practice within out trauma unit. Results Sixty-three patients met the inclusion criteria. Forty-seven had an intramedullary compared with 16 with transcortical configuration (ratio 3:1). Nine patients (19%) with intramedullary K-wires required removal of metalwork – seven due to prominent metalwork and two with wound infection. Four patients (25%) with transcortical K-wires required removal of metalwork – three due to prominent metalwork and one with failure of metalwork. There was no significant statistical difference between transcortical and intramedullary K-wire placement with regards to complication rates following tension band wiring of an isolated olecranon fracture requiring removal of metal (Chi squared test with Yates' correction p = 0.89). Conclusion We concluded that we found no difference in complications or metalwork removal rate in the placement of K-wire in tension band wiring for isolated olecranon fracture. We recognise our study was limited by small numbers and is based on the experience of

    Summary Background Operative treatment of higher degree acromioclavicular joint luxation is common. A new option is made available by the tight rope technique. It claims to provide adequate outcome with the use of a minimally invasive technique. First clinical studies justified its medical use, but the equivalence to established surgical methods remains unclear. We therefore analyzed radiographic data from patients that were treated with the tight rope system (TR) and compared them to those treated with K-wires (KW) fixation. Material/Methods Retrospective study with inclusion criteria: surgery for acromioclavicular joint luxation between 2004 and 2011, classified as Rockwood type III, no concomitant injury, first event injury. We compared pre- and post-operative X-rays with those taken at the end of treatment. Clinical data from follow-ups and radiographic data were evaluated. The main outcome variable was the remaining distance between the acromion and clavicle (ACD), as well as the coracoid process and clavicle (CCD). Results 27 patients (TR: n=16; KW: n=11) with comparable demographics and injury severity were included. Surgery reduced ACD (TR: p=0.002; KW: p<0.001) and CCD (TR: p=0.001; KW: p=0.003). Heterotopic ossification or postoperative osteolysis was not significantly associated with either one of the procedures. Three patients (18.75%) in the TR group showed impaired wound healing, migrating K-wires were recorded in 2 patients (18.2%) and impingement syndrome occurred in 1 patient (9.1%) with K-wires. Posttraumatic arthritis was not seen. There was a loss of reduction in 2 cases within the TR-group (12.51%) and 1 in the KW-group (9.1%). At last follow up, ACD and CCD were wider in both groups compared to the healthy side. Conclusions This study shows that the Tight rope system is an effective alternative in the treatment of higher degree acromioclavicular luxation and comparable to the established methods.

    The aim of this in vitro study is to compare the coronal microleakage of three common temporary restorative materials, namely Coltosol, Compoglass, and Zonalin, used in pediatric dentistry after endodontic treatment at different time intervals (1 week, 1, and 2 months) using dye penetration. Access cavities were prepared in 72 intact extracted premolar teeth. The samples were divided into three groups (n = 24) and filled with Coltosol, Compoglass, or Zonalin. After thermal cycling for 500 cycles (5-55°C), the teeth were immersed in 1% methylene blue dye at 37°C for 1 week (n = 8), 1 month (n = 8), and 2 months (n = 8). The samples were sectioned buccolingually, and the linear depth of dye penetration was measured using a stereomicroscope at 16 × magnification. The data were analyzed using Kruskal-Wallis test. There were no significant differences in the micro-leakage values of Coltosol and Zonalin or Zonalin and Com-poglass groups at 1 week (p > 0.05) or 1 month (p > 0.05) intervals, but a significant difference was noted between Coltosol and Compoglass groups (p < 0.01); Coltosol provided a more favorable coronal seal. No significant difference was found among the experimental groups at the 2-month interval (p > 0.05). At 1 week or 1 month of use, Coltosol showed better coronal seal. At 2 months, there was no significant difference apparent between the groups. A longer time lapse was associated with an increased likelihood of microleakage.

    Split thickness skin graft (STSG) harvesting from the anterior chest and abdominal wall skin is quite a difficult process. The main reason for the difficulty to perform this process is the unsuitable anatomic characteristics of the anterior trunk, such as irregular wavy-like surface over the ribs and lax abdominal wall skin resulting in collapse due to lack of adequate underneath supporting structures when a downward force is applied by the skin graft dermatome. Lower extremity and especially the thigh are generally chosen as the donor site where the STSGs are easily harvested from. However, extensive lower extremity burns, with or without other region burns, preclude harvesting auto STSGs from this invaluable anatomic site. We harvested K-wire assisted STSGs from the anterior chest and abdominal wall skin of 7 patients with lower extremity burns and also a patient that sustained motor vehicle collision. We encountered no problems in any of our patients both intra and postoperatively by using K-wire assisted STSG harvesting. All of the STSGs donor sites healed uneventfully without complications. In our opinion, K-wire assisted STSG harvesting must always be in the tool-box of any surgeon who deals with extensive burns with or without lower extremity burns and extensive traumas of lower extremities.

    Pediatric comminuted talar fractures are reported to be rare, and treatment options such as minimal internal K-wire fixation without using a tourniquet to prevent avascular necrosis have not previously been investigated. We report a case of a comminuted talar body and a non-displaced neck fracture with dislocation of the tibiotalar, talonavicular and subtalar joints with bimalleolar epiphyseal fractures in an 11-year-old boy due to a fall from height. We present radiological findings, the surgical procedure and clinical outcomes of minimal internal K-wire fixation without using a tourniquet. Avascular necrosis rates are reported to be between 0 % and 66 % after fractures of the neck of the talus and the talar body in children. The likelihood of developing avascular necrosis increases with the severity of the fracture. To avoid avascular necrosis in a comminuted talar fracture accompanied by tibiotalar, talonavicular, subtalar dislocations and bimalleolar epiphyseal fractures, a minimal internal K-wire fixation without the use of a tourniquet was performed. The outcome was evaluated by the American Orthopedic Foot and Ankle Society score (AOFAS). A score of 90 (excellent) was found at the end of the second year of follow up. Radiology revealed preservation of the joint with no evidence of avascular necrosis, and clinical findings revealed a favorable functional outcome after two years. 4.

  2. Drilling k-wires, what about the osteocytes? An experimental study in rabbits

    Introduction The function of osteocytes regarding osteonecrosis has been underestimated for a long time. Recently it has been suggested that apoptosis of osteocytes results in strong osteoclastic bone resorption. Death of osteocytes due to drilling may therefore increase the risk of K-wire loosening. The purposes of our in vivo study were to assess the minimal drill time needed to notice disappearance of osteocytes and to measure the distance of the empty osteocyte lacunae surrounding the drill tract in relation with the insertion time, directly and 4 weeks after drilling Kirschner (K-) wires into the femur and tibia of rabbits. Materials and methods Trocar tipped K-wires (70 mm length and 0.6 mm thickness) were drilled into the femur and tibia of 14 New Zealand white rabbits [mean body weight 2.81 kg (2.66–3.09 kg)]. Six rabbits were terminated following surgery (t = 0) and eight rabbits were terminated 4 weeks (t = 4) after surgery. Following termination, hematoxylin and eosin stained sections were cut from femur and tibia until the drill hole was visible. The sections were evaluated under a light microscope for the presence or absence of osteocytes in osteocyte lacunae surrounding the drill holes. Results All osteocyte lacunae were empty around the K-wires in 50 and 87% of the cases, directly and 4 weeks after the surgery, respectively. The osteocytes disappeared especially beyond a drilling time of 37 s (P = 0.011) and 27 s (P = 0.008) at t = 0 and t = 4, respectively. Furthermore, a significantly positive correlation was seen between the distances of the empty osteocyte lacunae surrounding the drill holes in relation with time at t = 0 (P = 0.008) and t = 4 (P = 0.000). Conclusion Although only drilling without cooling was studied, short drilling times may prevent the disappearance of osteocytes in case cooling is not used in clinical practice as is the case in percutaneous K-wire insertion.

    In completely displaced pediatric distal radial fractures, achieving satisfactory reduction with closed manipulation and maintenance of reduction with casting is difficult. Although the Kapandji technique of K-wiring is widely practiced for distal radial fracture fixation in adults, it is rarely used in pediatric acute fractures. Forty-six completely displaced distal radial fractures in children 7 to 14 years old were treated with closed reduction and K-wire fixation. One or 2 intrafocal K-wires were used to lever out and reduce the distal fragment's posterior and radial translation. One or 2 extrafocal K-wires were used to augment intrafocal fixation. Postoperative immobilization was enforced for 3 to 6 weeks (with a short arm plaster of Paris cast for the first half of the time and a removable wrist splint for the second half), after which time the K-wires were removed. Patients were followed for a minimum of 4 months. Mean patient age was 9.5 years. Near-anatomical reduction was achieved easily with the intrafocal leverage technique in all fractures. Mean procedure time for K-wiring was 7 minutes. On follow-up, there was no loss of reduction; remanipulation was not performed in any case. There were no pin-related complications. All fractures healed, and full function of the wrist and forearm was achieved in every case. The Kapandji K-wire technique consistently achieves easy and near-anatomical closed reduction by a leverage reduction method in completely displaced pediatric distal radial fractures. Reduction is maintained throughout the fracture-healing period. The casting duration can be reduced without loss of reduction, and good functional results can be obtained.

    The treatment of choice for first metacarpal base fractures is surgical. Open fixation is stable but causes tendinous adhesions. Percutaneous fixation is minimally invasive but is often followed by secondary displacement. Herein, we describe an alternative approach that combines advantages of both techniques through increasing stability of the Iselin technique by externally connecting the K-wires. Our series included 13 men of mean age 28 years. There were 13 fractures, 6 of which were extra-articular; there were 7 Bennett fractures, 5 of which had a large fracture fragment. After reduction, two 18 mm K-wires were driven medially crossing the 3 cortices of the first and second metacarpals. After bending them at 90-degree angles, the K-wires were connected externally in a construction allowing adaptation of the gap between the K-wires. Gentle immediate mobilization was allowed and the K-wires were removed 6 weeks later in clinic. At 16-month follow-up, mean pain score was 0.2/10 and Quick DASH was 2.9/100. Pinch grip was 81.8% of the contralateral side and grip strength 91.2%. The first web space opening was 79.1%. There was 1 secondary displacement with a good final result and 2 malunions. No arthritis was noted, but the follow-up was short. Our results show that the Iselin technique using locked K-wires is minimally invasive, stable, allows immediate mobilization, and K-wire removal in the office. Its indications may be extended to all fractures of the base of the first metacarpal whether articular or extra-articular.

    Four-corner fusion is a standard procedure for advanced carpal collapse. Several operative techniques and numerous implants for osseous fixation have been described. Recently, a specially designed locking plate (Aptus©, Medartis, Basel, Switzerland) was introduced. The purpose of this study was to compare functional results after osseous fixation using K-wires (standard of care, SOC) with four-corner fusion and locking plate fixation. 21 patients who underwent four-corner fusion in our institution between 2008 and 2013 were included in a retrospective analysis. In 11 patients, osseous fixation was performed using locking plates whereas ten patients underwent bone fixation with conventional K-wires. Outcome parameters were functional outcome, osseous consolidation, patient satisfaction (DASH- and Krimmer Score), pain and perioperative morbidity and the time until patients returned to daily work. Patients were divided in two groups and paired t-tests were performed for statistical analysis. No implant related complications were observed. Osseous consolidation was achieved in all cases. Differences between groups were not significant regarding active range of motion (AROM), pain and function. Overall patient satisfaction was acceptable in all cases; differences in the DASH questionnaire and the Krimmer questionnaire were not significant. One patient of the plate group required conversion to total wrist arthrodesis without implant-related complications. Both techniques for four-corner fusion have similar healing rates. Using the more expensive locking implant avoids a second operation for K-wire removal, but no statistical differences were detected in functional outcome as well as in patient satisfaction when compared to SOC.

    Extension-block pinning represents a simple and reliable surgical technique. Although this procedure is commonly performed successfully, some patients develop postoperative extension loss. To date, the relationship between extension-block Kirschner wire (K-wire) insertion angle and postoperative extension loss in mallet finger fracture remains unclear. We aimed to clarify this relationship and further evaluate how various operative and non-operative factors affect postoperative extension loss after extension-block pinning for mallet finger fracture. A retrospective study was conducted to investigate a relationship between extension block K-wire insertion angle and postoperative extension loss. The inclusion criteria were: 1) a dorsal intra-articular fracture fragment involving 30% of the base of the distal phalanx with or without volar subluxation of the distal phalanx; and (2)<3 weeks delay from the injury without treatment. Extension-block K-wire insertion angle and fixation angle of the distal interphalangeal (DIP) joint were assessed using lateral radiograph at immediate postoperative time. Postoperative extension loss was assessed by using lateral radiograph at latest follow-up. Extension-block K-wire insertion angle was defined as the acute angle between extension block K-wire and longitudinal axis of middle phalangeal head. DIP joint fixation angle was defined as the acute angle between the distal phalanx and middle phalanx longitudinal axes. Seventy five patients were included. The correlation analysis revealed that extension-block K-wire insertion angle had a negative correlation with postoperative extension loss, whereas fracture size and time to operation had a positive correlation. (correlation coefficient for extension block K-wire angle: -0.66, facture size:+0.67, time to operation:+0.60) When stratifying patients in terms of negative and positive fixation angle of the DIP joint,the independent t-test showed that mean postoperative extension loss is

    Most of the physician's attention during spinal surgery, when using wires and screws, is toward the avoidance of injuries of critical structures (nerves and vessels). When such wires are broken during surgery, the most important point is to take them out safely or, if it is impossible, to leaf them in secure place and follow the patient closely. Migrations of broken Kirschner wire (K-wire) are well known in literature; however, to the best of our knowledge, migration of a fractured K-wire during anterior atlantoaxial fixation of cervical spine has not been reported in the literature. We report a case in which a fractured K-wire was imbedded in the lateral mass of C1 for 3 years and then migrated to endanger the dominant right vertebral artery. By using posterior approach and drilling right part of posterior arch of C1, we manage to secure the vertebral artery. The broken K-wire was extracted successfully. In our case, with optimal follow-up, the burred wire inside hard bone was moved in delayed fashion to come out of the bone, grooving the dominant vertebral artery. Our recommendation is to inspect the K-wire before using it and to try retrieve as much as possible when removing it. Copyright © 2016 Elsevier Inc. All rights reserved.

    The aim of this study was to determine the feasibility of direct transcortical stabilization of fracture dislocations of the mandibular condyle (FDMCs) using narrow-diameter non-threaded Kirschner wire (K-wire). This retrospective review reports on the treatment outcomes for 12 patients (15 fractures) with FDMCs treated with open reduction using transcortical 0.027-inch K-wire stabilization. Postoperative parameters of relevance included infection, facial nerve function, hardware removal, mandibular range of motion, and radiographic determination of fracture union. Three patients had bilateral FDMCs and 9 had unilateral FDMCs (age range at time of injury, 14 to 72 yr; mean age, 32 yr). Postoperative follow-up ranged from 6 weeks to 2 years. Four patients required removal of K-wire hardware for different reasons. K-wires were removed because of infection in 1 patient. Another patient required removal because of migration of the pin into the joint space. One pin was removed electively and another was removed for nonspecific postoperative symptoms that resolved after pin removal. Persistent facial nerve deficit was observed in 1 patient. Open reduction with transcortical K-wire stabilization can achieve satisfactory outcomes for the treatment of FDMC. Further investigation is needed in determining the efficacy of this fixation technique in the management of FDMC. Copyright © 2017 American Association of Oral and Maxillofacial Surgeons.

    This purpose of this retrospective study is validation of an intraoperative robotic grading classification system for assessing the accuracy of Kirschner-wire (K-wire) placements with the postoperative computed tomography (CT)-base classification system for assessing the accuracy of pedicle screw placements.We conducted a retrospective review of prospectively collected data from 35 consecutive patients who underwent 176 robotic assisted pedicle screws instrumentation at Kaohsiung Medical University Hospital from September 2014 to November 2015. During the operation, we used a robotic grading classification system for verifying the intraoperative accuracy of K-wire placements. Three months after surgery, we used the common CT-base classification system to assess the postoperative accuracy of pedicle screw placements. The distributions of accuracy between the intraoperative robot-assisted and various postoperative CT-based classification systems were compared using kappa statistics of agreement.The intraoperative accuracies of K-wire placements before and after repositioning were classified as excellent (131/176, 74.4% and 133/176, 75.6%, respectively), satisfactory (36/176, 20.5% and 41/176, 23.3%, respectively), and malpositioned (9/176, 5.1% and 2/176, 1.1%, respectively)In postoperative CT-base classification systems were evaluated. No screw placements were evaluated as unacceptable under any of these systems. Kappa statistics revealed no significant differences between the proposed system and the aforementioned classification systems (P <0.001).Our results revealed no significant differences between the intraoperative robotic grading system and various postoperative CT-based grading systems. The robotic grading classification system is a feasible method for evaluating the accuracy of K-wire placements. Using the intraoperative robot grading system to classify the accuracy of K-wire placements enables predicting the postoperative accuracy of pedicle screw

    Background During long-term anticoagulation in atrial fibrillation, temporary interruptions (TIs) of therapy are common, but the relationship between patient outcomes and TIs has not been well studied. We sought to determine reasons for TI, the characteristics of patients undergoing TI, and the relationship between anticoagulant and outcomes among patients with TI. Methods and Results In the Rivaroxaban Once Daily, Oral, Direct Factor Xa Inhibition Compared With Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation (ROCKET AF), a randomized, double-blind, double-dummy study of rivaroxaban and warfarin in nonvalvular atrial fibrillation, baseline characteristics, management, and outcomes, including stroke, non–central nervous system systemic embolism, death, myocardial infarction, and bleeding, were reported in participants who experienced TI (3–30 days) for any reason. The at-risk period for outcomes associated with TI was from TI start to 30 days after resumption of study drug. In 14 236 participants who received at least 1 dose of study drug, 4692 (33%) experienced TI. Participants with TI were similar to the overall ROCKET AF population in regard to baseline clinical characteristics. Only 6% (n=483) of TI incidences involved bridging therapy. Stroke/systemic embolism rates during the at-risk period were similar in rivaroxaban-treated and warfarin-treated participants (0.30% versus 0.41% per 30 days; hazard ratio [confidence interval]=0.74 [0.36–1.50]; P=0.40). Risk of major bleeding during the at-risk period was also similar in rivaroxaban-treated and warfarin-treated participants (0.99% versus 0.79% per 30 days; hazard ratio [confidence interval]=1.26 [0.80–2.00]; P=0.32). Conclusions TI of oral anticoagulation is common and is associated with substantial stroke risks and bleeding risks that were similar among patients treated with rivaroxaban or warfarin. Further investigation is needed to determine the optimal

    Background: Supracondylar fractures are the commonest elbow injury in children. Most displaced Supracondylar fractures are manipulated and held with a medial/lateral entry or two lateral Kirschner wires. It was the purpose of this study to investigate the treatment of this injury in this unique patient population. Materials and Methods: This study was conducted in the Department of Orthopaedic surgery in M. M. Medical College from July 2005 to July 2010. One hundred seventy patients were recruited from Emergency and outpatient department having closed displaced Supracondylar fractures of humerus in children. They were treated either with medial-lateral pin fixation (n = 85) or with 2-lateral pin fixation (n = 85). All patients were operated under general anaesthesia. All patients were followed for 6 months. Results were analysed using Flynn's criteria. Statistical Analysis Used: Chi Square Test. Chi Square calculator was used as a software. Results: All children achieved union in a mean time of 4 weeks (range: 3-6 weeks). Post-operatively, eight patients (4.70%) got ulnar nerve injury and six (3.52%) patients got pin tract infection. Comparison between two groups such as cross K-wire group (85) and lateral K-wire group (n = 85) by using the Chi Square Test showed that in case of 8 weeks with (P-values = 0.89), in 16 weeks (P = 0.91) and 24 weeks (P = 0.85) with respective excellent, good, fair and poor categories were not found statistically significant. Conclusion: The lateral percutaneous pinning technique of displaced Supracondylar fractures of the humerus offers a viable alternative to the crossed pinning group as it offers the same stability without the incipient risk of iatrogenic ulnar nerve injury.

    To explore the clinical effect of manipulative reduction and lateral percutaneous K-wire fixation on supracondylar humerus fractures. From Feb. 2004 to Jun. 2010,128 cases of supracondylar humeros fractures in children (96 boys and 32 girls) were treated by manipulative reduction and lateral percutaneous K-wire fixation. The average age of the children was 8 years old ranging from 2 to 15 years. Among them, 112 cases were extension fractures, 16 were flexion type; 102 cases belonged to ulnar deviation, and 26 cases belonged to radial deviation. After treatment, the elbow flexion range and carrying angle of the children were measured under the Flynn evaluation standard while considering the postoperative complications status to analyze the clinical effect on manipulative reduction and lateral percutaneous K-wire fixation. All these children were followed up from 2 to 36 months (16 months on average). According to Flynn evaluation standard,the result were excellent in 116 children (90.6% of the total patients), good in 11 (8.6%), fair in 1 (0.8%). No infection, no ischemic muscular atrophy and no nerve damage had been found during the treatment. The manipulative reduction and lateral percutaneous K-wire fixation of supracondylar humerus fractures in children has small wound, is stable and reliable, easy to be operated, safe and effective and low cost. What's more, it can also avoid the complication caused by conservative treatment and operation. It is a good treatment of supracondylar humerus fractures in children.

    Background or Statement of Problem: As, the longevity of provisional restorations is related to, a perfect adaptation and a strong, long-term union between restoration and teeth structures, therefore, evaluation of marginal leakage of provisional restorative materials luted with cements using the standardized procedures is essential. Aims and Objectives: To compare the marginal leakage of the provisional crowns fabricated from Autopolymerizing acrylic resin crowns and bisphenol A-glycidyl dimethacrylate (BIS-GMA) resin crowns. To compare the marginal leakage of the provisional crowns fabricated from autopolymerizing acrylic resin crowns and BIS-GMA resin crowns cemented with different temporary luting cements. To compare the marginal leakage of the provisional crowns fabricated from autopolymerizing acrylic resin (SC-10) crowns cemented with different temporary luting cements. To compare the marginal leakage of the provisional crowns fabricated from BIS-GMA resin crowns (Protemp 4) cemented with different temporary luting cements. Methodology: Freshly extracted 60 maxillary premolars of approximately similar dimensions were mounted in dental plaster. Tooth reduction with shoulder margin was planned to use a customized handpiece-holding jig. Provisional crowns were prepared using the wax pattern fabricated from computer aided designing/computer aided manufacturing milling machine following the tooth preparation. Sixty provisional crowns were made, thirty each of SC-10 and Protemp 4 and were then cemented with three different luting cements. Specimens were thermocycled, submerged in a 2% methylene blue solution, then sectioned and observed under a stereomicroscope for the evaluation of marginal microleakage. A five-level scale was used to score dye penetration in the tooth/cement interface and the results of this study was analyzed using the Chi-square test, Mann–Whitney U-test, Kruskal–Wallis H-test and the results were statistically significant P < 0.05 the

    Three methods for temporarily filling root canals with calcium hydroxide pastes were compared. Each of 20 root canals of extracted, human, single-rooted teeth was shaped with hand instruments under standardized conditions up to ISO size 50 and filled using a syringe system, a lentulo spiral or an endodontic reamer. Quality of fillings was assessed radiographically and by inspecting ground preparations. Ridit (relative to an identified distribution) analysis was employed to confirm differences in frequencies of certain quality criteria obtained with various application methods. With regard to degree of obturation and occurrence of porosities, application of temporary fillings with a lentulo spiral or syringe system revealed significantly better results than application with hand instruments (reamer). No differences with regard to degree of obturation were detected when comparing results obtained with syringe or lentulo. Fewer porosities in the apical part of the root canal were seen, both on radiographs and ground sections, with the syringe system compared with the lentulo spiral. In the presence of some contradictory reports found in the literature, the present study suggests that, after straight or slightly curved root canals have been shaped up to at least ISO size 50, high quality temporary root canal fillings may be obtained by application of an aqueous suspension of calcium hydroxide with a syringe system.

    During the 80s and 90s, early and total excision of full thickness burns followed by immediate autograft was the most common treatment, with repeated excision and grafting, mostly for failed grafts. It was hypothesized, therefore, that delayed coverage with an autograft preceded by a temporary xenograft after early and sequential smaller excisions would lead to a better wound bed with fewer failed grafts, a smaller donor site, and possibly also a shorter duration of stay in hospital. We carried out a case control study with retrospective analysis from our National Burn Centre registry for the period 1997-2011. Patients who had been managed with early total excision and autograft were compared with those who had had sequential smaller excisions covered with temporary xenografts until the burn was ready for the final autograft. The sequential excision and xenograft group (n=42) required one-third fewer autografts than patients in the total excision and autograft group (n=45), who needed more than one operation (p<0.001). We could not detect any differences in duration of stay in hospital / total body surface area burned% (duration of stay/TBSA%) (2.0 and 1.8) (p=0.83). The two groups showed no major differences in terms of adjusted duration of stay, but our findings suggest that doing early, smaller, sequential excisions using a xenograft for temporary cover can result in shorter operating times, saving us the trouble of making big excisions. However, costs tended to be higher when the burns were > 25% TBSA.

However, costs tended to be higher when the burns were > 25% TBSA. PMID:28149249

    A series of 35 adult male industrial workers with displaced unstable transverse fractures of the shaft of the proximal phalanx of the fingers were treated with reduction and K-wire fixation leaving the metacarpophalangeal and interphalangeal joints free to move immediately after surgery. At final follow-up, the total active motion score of the injured finger was graded as excellent, good, fair, or poor if it was greater than 240°, 220-240°, 180-219°, or less than 180°, respectively. Complications were also documented. The results were compared with our previously published series of these fractures treated with two other techniques: percutaneous K-wires immobilizing the metacarpophalangeal joint and open reduction and interosseous loop wire fixation. The final TAM scores in the current study were excellent in 43%, good in 29%, fair in 14% and poor in 14%. Four out of the 35 patients (11%) had minor pin tract infection. These results were significantly better than the results following percutaneous K-wire fixation immobilizing the metacarpophalangeal joint indicating that immediate mobilization of all joints has a significant effect on the outcome.

    Intraosseous epidermal cysts (IECs) are rare benign lesions caused by the proliferation of epidermal cells within the bone. The pathogenesis of IEC remains unclear; however, trauma-triggered infiltration of the bone by epidermal elements has been suggested. Here, we present a case of an IEC in the metacarpal bone of the little finger associated with K-wire fixation for treatment of a fifth metacarpal fracture.

    Introduction Supracondylar fractures of humerus in children are usually treated with percutaneous pinning on emergency basis. When the operating time is delayed, percutaneous pinning is difficult due to massive swelling. Late presentation is common in developing countries. Aim To assess the outcome of open reduction and internal fixation with K-wire of widely displaced supracondylar fracture when operated later than 2 days after the injury. Materials and Methods A total of 52 children (aged 3-12 years) with widely displaced supracondylar fracture of humerus (Gartland type-III) who presented later than 2 days after injury were treated with open reduction through medial approach and fixation with cross K-wires. Results were assessed with Flynn’s criteria. Result: A total of 40 patients completed follow-up. Mean age of all (n=52) patients was 4.8 years (range 3-12 years). Mean delay of presentation was 7.5 days (range 2-14 days). Hundred percent patients had satisfactory results according to Flynn’s criteria. Two patients had pin infections. Conclusion Open reduction through medial approach and fixation with two cross K-wires is a reliable method of treatment for supracondylar fractures of humerus in children when the operation is delayed.

    To explore clinical effect of manipulative reduction and percutaneous K-wires fixation in treating supracondylar fractures of the humerus in children. From July 2010 to December 2012, clinical data of 52 children with supracondylar fractures of the humerus, which treated with manipulative reduction and percutaneous K-wires fixation, were retrospectively analyzed. Among them, there were 35 males and 17 females with an average age of 6.7 (ranged from 2.5 to 12) years old. All fractures were type Garland II - III fractures, and 51 cases were extension type and 1 case were flexion type. Flynn evaluation standard of elbow performance score were applied to evaluate clinical effects. All patients were followed up from 12 to 18 months with average of 16 months. According to Flynn evaluation standard of elbow performance score, 41 cases obtained excellent result, 8 good and 3 moderate. Manipulative reduction and percutaneous K-wires fixation for the treatment of supracondylar fractures of the humerus in children has many advantages, such as minimally invasive, rapid recovery, stable fixation. It could prevent osteofascial compartment syndrome, Volkmann Contracture and cubitus varus.

    The damage control surgery, with emphasis on laparostomy, usually results in shrinkage of the aponeurosis and loss of the ability to close the abdominal wall, leading to the formation of ventral incisional hernias. Currently, various techniques offer greater chances of closing the abdominal cavity with less tension. Thus, this study aims to evaluate three temporary closure techniques of the abdominal cavity: the Vacuum-Assisted Closure Therapy - VAC, the Bogotá Bag and the Vacuum-pack. We conducted a systematic review of the literature, selecting 28 articles published in the last 20 years. The techniques of the bag Bogotá and Vacuum-pack had the advantage of easy access to the material in most centers and low cost, contrary to VAC, which, besides presenting high cost, is not available in most hospitals. On the other hand, the VAC technique was more effective in reducing stress at the edges of lesions, removing stagnant fluids and waste, in addition to acting at the cellular level by increasing proliferation and cell division rates, and showed the highest rates of primary closure of the abdominal cavity. RESUMO A cirurgia de controle de danos, com ênfase em peritoneostomia, geralmente resulta em retração da aponeurose e perda da capacidade de fechar a parede abdominal, levando à formação de hérnias ventrais incisionais. Atualmente, várias técnicas oferecem maiores chances de fechamento da cavidade abdominal, com menor tensão. Deste modo, este estudo tem por objetivo avaliar três técnicas de fechamento temporário da cavidade abdominal: fechamento a vácuo (Vacuum-Assisted Closure Therapy - VAC), Bolsa de Bogotá e Vacuum-pack. Realizou-se uma revisão sistemática da literatura com seleção de 28 artigos publicados nos últimos 20 anos. As técnicas de Bolsa de Bogotá e Vacuum-pack tiveram como vantagem o acesso fácil ao material, na maioria dos centros, e baixo custo, ao contrário do que se observa na terapia a vácuo, VAC, que além de apresentar

    Background. K-wires are thought to be extremely safe implants and complications as a result of direct insertion or migration are very rare. Complications may be life-threatening in some instances where migration results in injury to vital organs. We report one such case where antegrade migration of K-wire from the hip resulted in injury to external iliac artery and formation of external iliac artery-appendicular fistula. No such complication due to migration has ever been reported in the literature. Case Description. A 15-year-old boy presented with lower abdominal pain, right lower limb swelling and pain, inability to walk, and rectal bleeding for 1 month after 2 K-wires had been inserted in his right hip joint for treatment of slipped capital femoral epiphysis the previous year. On investigation, he was diagnosed to have external iliac artery-appendicular fistula for which he was surgically treated. Clinical Relevance. Antegrade migration of K-wire from hip joint may lead to life-threatening injuries which can be minimized by bending the end of the K-wire, keeping the tip protruding outside the skin wherever possible and by early removal of K-wire once its purpose has been achieved.

    Metacarpal (MC) fractures are very common, accounting for 18% of all fractures distal to the elbow. Many MC fractures can be treated non-operatively; however, some are treated most effectively with surgical stabilization, for which there are multiple methods. It was postulated that plates would have a significantly higher (P < 0.05) load to failure than crossed K(XK)-wires and that intramedullary metacarpal nails (IMNs) and XK-wires would have equivalent load to failure. Mid-diaphyseal transverse fractures were created in 36 synthetic metacarpals and stabilized using nails, XK-wires or non-locking plates. Three-point bending was performed with continuous recording of load and displacement. Statistical analysis was performed using single factor ANOVA and Scheffe's test. Statistical significance was defined as P < 0.05. Biomechanical testing revealed significant differences between groups in load-to-failure. Average load to failure was significantly greater in the plate (1669 ± 322 N) than the XK-wire (146 ± 56 N) or IMN (110 ± 43 N) groups. The loads to failure of the K-wires and nails were equivalent. Plates were 11 and 15 times stronger in three-point bending than the K-wires and nails, respectively. There was no statistically significant difference between strengths of the K-wires and nails. Although plates are the most stable means of fixation of midshaft metacarpal fractures, if minimally-invasive techniques are indicated, intramedullary nails may provide equivalent stability as commonly-used XK-wires. Although some studies have shown favorable clinical outcomes with IMNs, additional clinical correlation of these biomechanical results to fracture healing and outcomes is needed. © 2015 Chinese Orthopaedic Association and Wiley Publishing Asia Pty Ltd.

    Introduction: Materials used to fabricate provisional restorations can be classified as acrylics or resin composites. Provisional crows can be either prefabricated or custom made. Acrylics: These materials have been used to fabricate provisional restorations since the 1930s and usually available as powder and liquid. They are the most commonly used materials today for both single-unit and multiple-unit restorations. In general, their popularity is due to their low cost, acceptable esthetics, and versatility. Composites: Composite provisional materials use bis-acryl resin, a hydrophobic material that is similar to bis-GMA. Composites are available as auto-polymerized, dualpolymerized and visible light polymerized. Preformed Crowns: Preformed provisional crowns or matrices usually consist of tooth-shaped shells of plastic, cellulose acetate or metal. They are commercially available in various tooth sizes and are usually selected for a particular tooth anatomy. They are commonly relined with acrylic resin to provide a more custom fit before cementation, but the plastic and metal crown shells can also be cemented directly onto prepared teeth. Aims and Objectives: The aim of this study is to choose a material to serve as a better interim prosthesis and to compare three different properties – flexural strength, compressive strength, and color stability. Materials and Methods: The samples were made with three different provisional materials (Revotek LC, Protemp 4, TemSpan). Result: It was inferred from the study that no one material was superior in all three tested parameters. PMID:27829758

    Airway clearance techniques include positive expiratory pressure, commonly used in our clinical practice, and a recently introduced temporary positive expiratory pressure device called UNIKO(®). It is unclear which one provides the best benefit to patients. The aim of this observational 4-year study was to retrospectively compare the efficacy of and specific indications for temporary positive expiratory pressure compared to positive expiratory pressure in a standard rehabilitation program. We retrospectively collected data from 162 subjects (107 males, mean age 70±9 years, 97 with primary diagnosis of chronic obstructive pulmonary disease, 65 with bronchiectasis), 51 treated with temporary positive expiratory pressure and 111 with positive expiratory pressure. Subjects showed significant improvement in ratio of partial pressure arterial oxygen and fraction of inspired oxygen (p<0.001), forced vital capacity, forced expiratory volume in one second, peak expiratory flow, arterial oxygen saturation, and partial pressure arterial oxygen with no significant difference between positive expiratory pressure and temporary positive expiratory pressure groups apart from forced expiratory flow, which increased only in the positive expiratory pressure group. Evaluating specific subgroups, temporary positive expiratory pressure was more effective than positive expiratory pressure in improving gas transfer in subjects with emphysema and in those on oxygen therapy, as the effective supplement oxygen flow decreased significantly (p=0.034 and 0.046 respectively for temporary positive expiratory pressure vs. positive expiratory pressure). In subjects on mechanical ventilation, positive expiratory pressure was superior to temporary positive expiratory pressure in increasing forced expiratory flow (p=0.018). The physiological parameters of both groups improved significantly and similarly. Subgroup analysis suggests that temporary positive expiratory pressure could provide some

    In recent years, labour market has really changed in Italy: in addition to traditional categories of workers, self-governing or subordinate, a "tertium genus" was born, that of "temporary workers". This new modality allows firms which need to introduce temporary workers in production processes, to find them through the activity of skilled intermediary agencies. This type of agencies, regularly authorized by the Ministry of Labour, was born to select subordinates, who will work in other firms, without engagement. (The low which regulates temporary work in Italy is the Act n. 196 of 1997). The subject analysed the most closely in the text, is the really interesting question of responsibility for prevention, safety and health in work places: in fact, temporary work creates a complex system of bilateral relations, but the only real work contract is between provider firms and temporary workers. The Act n. 196 states that the provider firm must fulfill its duties of contribution, security, aid and insurance against industrial accidents and occupational diseases. Therefore, according to a series of argumentations developed in the text, only the occupational health consultant designated by the temporary agency is reasonably responsible for medical supervision, but he has to coordinate and collaborate with the occupational health consultant of third firms (Directive 383 of 1991 and article 7 of Legislative Decree n. 626 of 1994). On the contrary, firms which need temporary workers, must fulfill duties of information and training for workers. As a consequence, to draw a conclusion, on the ground of principles of European Union and national laws (in force since '50s in this field), the responsibility for medical supervision falls on temporary agencies; on the contrary, economic responsibility falls on firms which request workers, in order to achieve protection of workers' health.

    In some infants with developmental dysplasia of the hip, concentric closed reduction, although initially achievable, cannot be maintained even by casting because of a deficient posterior acetabular wall. Usually, these hips will redislocate in the cast and a rereduction will be necessary, often requiring an open reduction subsequently. A 3-year retrospective review of 88 infants, (M/F; 14/74) 6 to 12 months of age with 124 dislocated hips, was conducted to assess the efficacy of percutaneous Kirschner wire fixation in achieving permanent hip stability. A "hip-at-risk" instability test was developed to detect potentially unstable hips at the time of closed reduction that might redislocate in the hip spica cast, and these hips were stabilized with a percutaneous K-wire through the greater trochanter into the pelvic bone. The hip instability test was positive in 27 hips and negative in 97. Percutaneous K-wire fixation was used to stabilize 21 hips with a positive hip instability test. All 21 unstable hips that were stabilized with the K-wire technique maintained their concentric reduction and went on to stable development. No K-wire breakage was encountered and only 1 superficial pin tract infection occurred. K-wire stabilization of unstable closed reductions is a safe, reliable technique for maintaining concentric hip reduction in infants 6 to 12 months of age with developmental dislocation of the hips.

For water absorption/desorption studies rectangular samples (40 mm × 10 mm × 1 mm) of each material were prepared, immersed in deionized water (DW, control) and artificial saliva (AS), and weighed at regular time intervals. %solubility and diffusion coefficients (D) for uptake/loss processes were calculated and compared with theoretical predictions. Polymerization exotherm (cylindrical samples 10 mm × 18 mm) and flexural moduli were measured (three point bending; rectangular samples 80 mm × 10 mm × 4 mm, dry and after 9 days storage in DW). The data were compared statistically. QT and nBMA/PEM had lower %equilibrium uptakes/loss in DW (0.68%/0.884% and 0.64%/0.895% respectively). QT had the lowest water absorption/desorption D (P<0.05) compared to the three monomethacrylates, in DW and AS. %solubility for all systems showed no differences in DW (P>0.05), but a difference for QT in AS (P<0.05). QT reached its maximum temperature rapidly (∼2 min; 3 monomethacrylates ∼7-13 min). The commercial materials exhibited high peak temperatures (∼51°C, P<0.05; experimental materials ∼43°C). QT had a higher flexural modulus (∼4 GPa; 3 monomethacrylates ∼0.7-1 GPa) for dry and wet samples. The moduli for commercial materials reduced significantly after immersion in DW; there was no difference between the dry and wet experimental materials samples (P>0.05). The experimental materials merit further studies since they presented with lower setting exotherms, and contained no phthalate plasticizer, thus being less of a risk to patients.

    Background Infections of bone and joint tissues following arthroplasty surgeries remain a major challenge in orthopaedic settings. Methicillin resistant Staphylococcus aureus (MRSA) is recognised as an established pathogen in such infections. Combination therapy using linezolid and bacteriophage impregnated in biopolymer was investigated in the present study as an alternative strategy to prevent MRSA colonisation on the orthopaedic implant surface. Methodology Coating of stainless steel orthopaedic grade K-wires was achieved using hydroxypropylmethlycellulose (HPMC) mixed with phage alone, linezolid alone and phage and linezolid together. The potential of these agents to inhibit adhesion of S.aureus (MRSA) 43300 on K-wires was assessed. Coated and naked wires were analysed by scanning electron microscopy (SEM) and fluorescent staining. Result Significant reduction in bacterial adhesion was achieved on phage/linezolid wires in comparison to naked as well as HPMC coated wires. However, maximum reduction in bacterial adherence (∼4 log cycles) was observed on the wires coated with phage-linezolid combination. The frequency of emergence of resistant mutants was also negligible in presence of both the agents. Conclusion This study provides evidence to confirm that local delivery system employing linezolid (a potent protein synthesis inhibitor) along with a broad spectrum lytic bacteriophage (capable of self-multiplication) is able to attack the adhered as well as surrounding bacteria present near the implant site. Unlike other antibiotic based therapies, this combination has the potential to significantly restrict the emergence of resistant mutants, thus paving the way for effective treatment of MRSA associated infection of medical implants.

Between June 2007 and March 2014, 41 patients (28 men, 13 women) with isolated closed mallet finger fracture were treated using two K-wires. In the cohort, the mean joint surface involvement was 44.3% (range: 28-62%). With a mean period of 23.6 months, patient follow-up lasted 13-34 months. The fingers were evaluated for loss of extension and flexion of the (DIP) joints. The results were graded using Crawford's criteria. Union of all fractures took place at an average of 5.5 weeks after the surgical procedure. Average extension lag was 4°, and active flexion 71°. According to the Crawford rating scale, 35 fingers were excellent, four were good, one was fair, and one was poor. Pressing fixation of the bone fragment with the end of a K-wire was a useful technique in the treatment of mallet finger fractures. Therapeutic IV. Copyright © 2015. Published by Elsevier Ltd.

    Pediatric radial neck fractures are uncommon. Severely displaced and angulated fractures usually require treatment. Our goals for treatment are to avoid incision, reduce the fracture adequately with no reduction loss, and achieve good postoperative function. We aimed to observe the clinical outcomes of closed reduction with the percutaneous leverage technique and internal fixation with Kirschner-wires (K-wires) to treat angulated radial neck fractures in children.From January 2011 to April 2013, we treated 16 cases of angulated radial neck fracture in 12 boys and 4 girls. Five fractures were type II and 11 fractures were type III using the O'Brien classification. One K-wire was percutaneously introduced into the fracture site using the leverage technique to attain good reduction. Two K-wires were introduced from the proximal to the distal areas of the fracture site. The elbow was immobilized by cast in 90° of flexion and the forearm in supination for 3 to 4 weeks. The K-wires were removed at 3 to 4 weeks postoperatively. All cases were followed up for a mean duration of 3 years 6 months.According to the Metaizeau reduction classification, 12 cases were excellent, and 4 cases were good.

    Tension-band wiring is a popular method of internal fixation for simple olecranon fractures. Although fracture union rates and clinical outcomes are good, up to 80% of patients require removal because of prominent/symptomatic metalwork. The current literature remains unclear as to the best orientation of the longitudinal wires to minimize hardware failure. The aim of this study was to determine the surgically modifiable factors related to spontaneous wire pullout. A retrospective review of hospital theater records over a period of 6 years was performed to identify all olecranon tension-band wire procedures. Preoperative radiographs were used to confirm and classify the fracture. Intraoperative and postoperative radiographs were analyzed for a number of wire-associated variables: wire length within the ulna, medullary/cortical position, parallelism of wires, proximal wire prominence, wire angle relative to the ulna, distance from the articular surface, fracture gap, and subsequent pullout. A total of 182 wires were analyzed. The mean age was 52.5 years, and the mean radiographic follow-up period was 7.3 months. Intramedullary wires had a mean pullout of 5.5 mm compared with 2.4 mm for transcortical wires (P < .0001). A multiple regression model noted 7 independent variables affecting wire pullout: age, bent wires, medullary/transcortical wire positioning, proximal prominence, ulnar shaft angle, distance from the articular surface, and articular step. To minimize postoperative pullout of wires, we suggest anatomic reduction and transcortical wire orientation, without bending, in the subchondral bone close to the articular surface.

  17. Comparative temporary threshold shifts in a harbor porpoise and harbor seal, and severe shift in a seal.

    Anthropogenic noise may cause temporary hearing threshold shifts (TTSs) in marine mammals. Tests with identical methods show that harbor porpoises are more susceptible to TTS induced by octave-band white noise (OBN) centered around 4 kHz than harbor seals, although their unmasked (basic) hearing thresholds for that frequency are similar. A harbor seal was exposed for 1 h to an OBN with a very high sound pressure level (SPL), 22-30 dB above levels causing TTS onset. This elicited 44 dB TTS; hearing recovered within 4 days. Thus, for this signal and this single exposure, permanent threshold shift requires levels at least 22 dB above TTS onset levels. The severe TTS in the seal suggests that the critical level (above which TTS increases rapidly with increasing SPL) is between 150 and 160 dB re 1 μPa for a 60 min exposure to OBN centered at 4 kHz. In guidelines on TTS in marine mammals produced by policy makers in many countries, TTS is assumed to follow the equal energy hypothesis, so that when the sound exposure levels of fatiguing sounds are equal, the same TTS is predicted to be induced. However, like previous studies, the present study calls this model into question.

    Our objective was to elucidate the differences in treatment outcomes caused by the different mechanics of temporary anchorage devices (TADs) and Class III elastics in patients with Class III malocclusions. Records of 23 patients with Angle Class III malocclusion were selected retrospectively. All had been treated with nonextraction comprehensive orthodontic treatment; 11 were treated with TADs and 12 with Class III elastics. Pretreatment and posttreatment lateral cephalograms were used for evaluation of the treatment outcomes. A paired t test and a Student t test were used for statistical analysis. In both groups, proper overjet and Class I molar relationships were achieved, and the occlusal plane was rotated counterclockwise. In the elastics group, distal tipping of the mandibular molars, extrusion of the mandibular incisors and maxillary molars, clockwise rotation of the mandibular plane angle, and increased ANB angle were observed. In the TADs group, distal tipping and intrusion of the mandibular molars, bodily movement of the mandibular incisors, and reduced mandibular plane angle were observed. In nonextraction treatment for Class III malocclusions, the mandibular plane angle was increased in the elastics group, whereas it was decreased in TADs group. Thus, we suggest that Class III elastics are preferred for low-angle, short-face patients, whereas TADs are preferred for high-angle, long-face patients.

    Dislocated combined injuries of the upper cervical spine such as C 1/2 fractures require occipitocervical fusion, especially if the dislocation can not be redressed using halo vest immobilisition. We report on the clinical course and outcome of a young woman who sustained complex cervical spine injuries. Closed reduction and a percutaneous transfixation of C 1/2 with k-wires (Magerl) and an additional halo vest immobilisition was performed to avoid permanent fusion. The 25 year old patient was involved in a motor vehicle accident that resulted in a dislocated Jefferson's fracture, an odontoid fracture type II (Anderson and d'Alonso) with protrusion into the foramen magnum, and a dislocated C 6/7 fracture. A ventral spondylodesis C6/7 was followed by temporary dorsal spondylodesis C1/2 with k-wires (Magerl) and additional halo vest immobilisition after closed reduction. The temporary percutaneous fixation C1/2 was removed after 11 weeks, as was the halo vest immobilisition. After removing the temporary percutaneous fixation (k-wires) and the halo system, the patient showed very good functional results in terms of range of motion with only minor discomfort. Complex injuries of the upper cervical spine that cannot be retained by external fixation often require an occipitocervical fusion or fixation of C1/2. In the case presented, the temporary percutaneous fixation (Magerl) with k-wires was terminated after 3 months to avoid significant functional impairment. Younger patients benefit most from temporary fusion of the upper cervical spine, which results in better functional outcome and only minor pain.

  20. A multiplanar complex resection of a low-grade chondrosarcoma of the distal femur guided by K-wires previously inserted under CT-guide: a case report

    PubMed Central

    2014-01-01

    Background In muscular skeletal oncology aiming to achieve wide surgical margin is one of the main factors influencing patient prognosis. In cases where lesions are either meta or epiphyseal, surgery most often compromises joint integrity and stability because muscles, tendons and ligaments are involved in wide resection. When lesions are well circumscribed they can be completely resected by performing multi-planar osteotomies guided by computer-assisted navigation. We describe a case of low-grade chondrosarcoma of the distal femur where a simple but effective technique was useful to perform complex multiplanar osteotomies. No similar techniques are reported in the literature. Case presentation A 57 year-old Caucasian female was referred to our department for the presence of a distal femur chondrosarcoma. A resection with the presenting technique was scheduled. The first step consists of inserting several K-wires under CT-scan control to delimitate the tumor; the second step consists of tumor removal: in operative theatre, following surgical access, k-wires are used as guide positioning; scalpels are externally placed to k-wires to perform a safe osteotomy. Conclusions Computed assisted resections can be considered the most advantageous method to reach the best surgical outcome; unfortunately navigation systems are only available in specialized centres. The present technique allows for a multiplanar complex resection when navigation systems are not available. This technique can be applied in low-grade tumours where a minimal wide margin can be considered sufficient. PMID:25123066

    Articular penetration of K-wires is a possible complication of the modified tension band wiring technique. However, there is no clear information or evidence regarding the entry point or introduction angle for K-wires to avoid this complication. The aim of this experimental study was to evaluate the effect of varying K-wire insertion points and angles on the risk for articular penetration during modified tension band wiring for olecranon fractures. All anatomical measurements were made on 50 cadaveric ulnas, and all other measurements were performed on exact foam replications of the 50 cadaveric ulnas. Morphometric measurements, including olecranon height and heights of the central, radial and ulnar facets of the semilunar notch, were taken. In the sagittal plane, articular angle and tubercle angle were measured. Two 1.6-mm parallel K-wires were inserted from 0, 5 and 8 mm anterior to the dorsal cortex of the olecranon process at angles of 20° and 30°. K-wire articular penetration was evaluated both visually and radiographically. The mean central, radial and ulnar heights of the semilunar notch were 17.3 mm (14.7-20.0), 16.2 mm (12.0-21.0) and 15.8 mm (13.30-20.5), respectively. We observed no articular penetration at the 0-mm level at 20° and 30° (0 mm 20° and 0 mm 30°, respectively) or at 5 mm 20°. At 8 mm 30° wire introduction, more than 64% articular penetration was observed on either facet. The sequence from least to most likely to cause articular penetration was: 0 mm = 5 mm 20° > 5 mm 30° = 8 mm 20° > 8 mm 30°. The radial height of the semilunar notch was negatively correlated to the risk of articular penetration, when the wire was introduced at 8 mm 30°, 8 mm 20° and 5 mm 30° (all p<0.047). There were poor correlations between radiological and direct observational assessments, particularly for 8 mm 20° and 5 mm 30°. The frequency of intra-articular positioning for those observed to be radiologically extra-articular was 4/28 (14.3%) for 8 mm

    To assess the therapeutic results of open reduction and internal fixation with crossed K-wires via lateral approach for displaced supracondylar fractures of the humerus in children. We prospectively followed 52 children who presented with Gartland type 3 displaced supracondylar fractures of the humerus and were managed by open reduction and internal fixation with crossed K-wires via lateral approach.There were 37 male and 15 female patients; average age was 7.39 years. The most common mechanism of trauma was fall while playing (n=23), followed by fall from height (n=20), road traffic accidents (n=5) and fall from standing height (n=2). In 2 cases, mode of injury was not available. The mean follow-up was 12 months and patients were assessed according to Flynn's criteria. Lateral approach provided an excellent view of the lateral column between two nervous planes and enabled an anatomical reduction in all cases. Immobilizing the elbow at 90 degrees or more of flexion was not needed after cross K-wire fixation. Majority of patients regained full range of motion within 6 weeks of pin removal. Two patients had postoperative ulnar nerve injuries that resolved after pin removal. The common late complication of cubitus varus was not seen in any patient. Delayed presentation to the emergency department, repeated manipulations by bone setters and massage with edible oil were responsible for stiffness in 5 patients. Superficial pin tract infection was noted in 5 patients that resolved with dressings and antibiotics. No deep infection occurred. A detailed clinical examination and radiographic analysis was done at final follow-up. They included measurement of carrying angle and range of movements of both operated and normal sides, and radiographs of both upper limbs for comparison. According to Flynn's criteria, 90.4% patients showed satisfactory results. Lateral approach for open reduction and internal fixation of the widely-displaced supracondylar fracture of the humerus is

  3. Temporary nursing staff - cost and quality issues.

    PubMed

    2011-02-01

    This paper is a report of a comparative study of temporary and permanent staff work activity, cost and quality of care. Temporary nurse staffing can consume significant proportions of the health service wages bill, and this is unlikely to fall owing to recruitment and retention problems, high sickness absence and the tendency for staff to work 'casually'. If temporary workers are here to stay, then what impact do they have on inpatient care? For example, do ward nursing quality and costs change when temporary staff are employed? Ward patient dependency, nursing activity, workload, staffing and data on quality were collected using non-participant observation, document analysis, staff and patient interviews in 605 United Kingdom general and specialist wards between 2004 and 2009. These wards were divided into two groups: 368 employing only permanent staff during data collection and 237 with permanent, and temporary staff in the ward team at the time when the observations were made. Workloads and time out (sickness absence, etc.) in wards employing temporary staff were greater than in units with permanent staff only, thereby justifying hiring short-term staff. Wards with temporary and permanent staff were more expensive to run and working styles were different. Overall quality scores, however, were no different in the two types of ward. Ward managers need to monitor temporary staffing and the effect they have on nursing activity and quality. Similar studies in mental health, learning disability and community nursing would generate additional insights. © 2010 Blackwell Publishing Ltd.

    Salter-Harris type IV fracture of the proximal phalanx with 90° rotation of the epiphysis is very rare. We report on a case of Salter-Harris type IV fracture of the proximal phalanx of the thumb with rotation of the epiphysis and document the outcome 10 years after surgery. A 5-year old boy presented with Salter-Harris type IV fracture of the thumb with 90° rotation of the epiphysis. Open reduction and K-wire fixation was done. Ten years later, the injured thumb was smaller in width when compared to the contralateral thumb, although there was no length discrepancy. Clinically, there was full range of motion. Radiologically, the physis was still open but there were minor irregularities at the adjacent metaphyseal base and epiphysis. The diaphysis of the injured proximal phalanx had a constricted appearance when compared to the contralateral normal side. After an extensive literature review, we found one reported case which was similar to our case and had long term assessment. At skeletal maturity, there was complete remodeling and full range of motion of the digit with no shortening. The X-ray showed a constricted diaphysis of the proximal phalanx with an identical appearance to our case. We present a rare case of Salter-Harris type IV fracture of the proximal phalanx of the thumb with rotation of the epiphysis. Long term outcome was satisfactory but there was diaphyseal constriction leading to a narrower thumb. Copyright © 2016 The Author(s). Published by Elsevier Ltd.. All rights reserved.

    To evaluate vascular flow through temporary vascular shunts inserted into peripheral arteries and veins and the repercussion, on the arterial perfusion, of venous ligation and venous shunt insertion in an experimental model for damage control. Experimental study in pigs. Animals were distributed in 5 groups: group 1, right external iliac artery (EIA) shunting and right external iliac vein (EIV) ligation; group 2, right EIA shunting and right EIV shunting; group 3, right EIV ligation; group 4, right EIV shunting; group 5, no vascular shunting and no venous ligation. Flowmeters were used to measure vascular flow on right and left external iliac vessels, and blood samples were collected from the EIVs for biochemical analysis. A right anterior limb biopsy was performed before shock. Hemorrhagic shock was induced through the external right jugular vein, until the vascular flow through right iliac external artery shunt or right iliac external vein shunt (group 4) ceased or until the animal's death. After the end of the experiments, biopsies of bilateral hind limb were obtained for histologic analysis. For statistical analysis, Microsoft Office Excel 2007 and BioEstat 5.0 (2007) were used. In the absence of hemorrhagic shock, venous ligation (group 1) was associated with a 38.8% reduction (P < 0.05) and venous shunting with a 28.4% reduction on the vascular flow through the arterial shunt. When associated with hemorrhagic shock, the mean vascular flow on the right EIA was 13 mL/min and on the left EIA was 41.2 mL/min; on group 2, the right EIA flow was 8.5 mL/min and the left EIA flow was 8.1 mL/min. When associated with hemorrhagic shock, the pO2 was 25.8 mm Hg on right EIV and 33.8 mm Hg on the left EIV for group 1 (P < 0.05), whereas for group 2, the pO2 was 22.6 mm Hg on right EIV and 22.8 mm Hg on the left EIV. On group 1, serum potassium was 3.84 mEq/L on the right EIV and 3.96 mEq/L on the left EIV, whereas on group 2, it was 7.1 mEq/L on the right EIV and 5.88 m

    Isolated lower segment sacral fracture is very rare. To the best of our knowledge, there is only one case report of S4 stable fracture that was treated conservatively. Here, we report a 12-year-old girl who sustained an isolated S5 fracture with anterior displacement of S5 and coccyx on S4. The patient initially was managed conservatively 1 month and 25 days. On the failure of this treatment procedure, the patient was treated surgically by partial coccygectomy with S4-S5 fixation after reduction by 2 K-wires. Sacral fracture is difficult to diagnose, especially when the patient has multiple injuries. This is because the emergency doctor may not perform a neurologic examination of the perineum and may miss its diagnosis. Another reason for its misdiagnosis is that the routine anteroposterior plain X-ray may not detect it. Trauma patients with sacrococcygeal pain and tenderness should raise concerns about sacral fracture, and a lateral plain X-ray and/or computed tomography of the sacrococcygeal spine should be performed. Neurologic deficit is rare in lower sacral segment fracture; hence, a trial of conservative management (same as for coccygeal fracture) should be tried first. If the patient does not respond and there is displacement, surgical intervention can be used, because it has a very good response from the patient. In the presence of a neurological deficit, however, surgical intervention should be attempted as soon as possible. Copyright © 2016 Elsevier Inc. All rights reserved.

    Flexion-type supracondylar fractures are challenging to treat because, unlike extension-type fractures, it is difficult to take advantage of the intact periosteal hinge to stabilize the fracture fragments during percutaneous pinning. Some authors have described closed reduction of these fractures with the elbow in extension, followed by percutaneous K-wire fixation. However, percutaneous pinning with elbow in extension is technically difficult, time consuming, and usually requires the help of a skilled assistant because of persistent fracture instability. To circumvent these difficulties, we utilized a 'push-pull' maneuver, which simplifies the closed reduction and fixation of these difficult fractures. We describe the surgical technique for the 'push-pull' method and report radiographic outcomes of a case series of children with flexion-type supracondylar fractures treated using this technique. A retrospective review of medical records and radiographs of all children who underwent operative treatment of a flexion-type supracondylar humeral fracture using the 'push-pull' method in a tertiary-level children's hospital between January 2009 and January 2014 was carried out. Radiographic outcomes were reported using descriptive statistics. There were a total of nine patients (five females, four males), average age 9.8 years (4-14 years). Seventy-eight percent (7/9 patients) of the children had type III injuries, whereas 22% (two children) had type II injuries. The average duration of surgery was 41 min (24-60 min). No intraoperative or postoperative complications were recorded. Postoperative radiographic measures showed that the anterior humeral line passed through the middle third of capitellum in 78% of patients (7/9 patients), whereas it passed posterior to it in 22% (two patients). The average humerocapitellar angle was 30° (21-44°) and the anterior coronoid line was unbroken in 44% (4/9 patients). The average humeroulnar angle was 13° (8-20°) of valgus

    Researchers have studied the water content at different skin depths. Since skin differs among tissue depth, we sought to determine the depth variability of the water content after moisturizing formulation application. Furthermore, we compared the effects of formulations with different type of manufacturing processes (hot and cold process). To characterize the variations in the water content at different depths in the skin, measurements were done on the center of the inner forearm middle line of 18 sitting healthy women, before and after 1, 3, and 5 h of the application of two different moisturizing formulations (hot and cold process). Measurements included stratum corneum hydration via capacitance (SC) at 1.25 MHz (30-40 μm), and dermal water via tissue dielectric constant (TDC) at 300 MHz to depths of 500, 1500, and 2500 μm. There were significant differences between the SC mean values at all evaluated time intervals after application of both formulations when compared to baseline before application (T0). The SC mean values at 1 and 3 h are higher than those of the 5 h post application for both formulations. When comparing the formulations, hot formulation shows higher SC levels at 3 and 5 h, than cold formulation. TDC mean values to skin depths of 500 and 1500 μm increased after the application for both formulations. This increase was statistically significant at 1 and 3 h, when compared with T0. At 5 h no increases were seen in the TDC for any of the formulations. When comparing the mean values of each time evaluated, there is no statistically significant difference between the two formulations at depth of neither 500 μm nor 1500 μm. TDC mean value to a depth of 2500 μm does not increase after the application of any of the formulations. Hot and cold formulations are effective moisturizers; however, a distinct profile was obtained for each. When water content averages were compared, the effect of hot formulation in the superficial layers of the skin was

    The Shanghai Floating Population Study was carried out in 1984 with the objective of estimating the number of temporary residents in the city. This was supplemented by the Shanghai Temporary Migration Survey, which obtained information from a sample of 8716 temporary migrants living in households with permanent residents. The Beijing Temporary Migration Survey of 1985 also obtained information from temporary migrants yielding a sample of 3418. The sex ratio of 68 males per 100 females among Beijing's household temporary migrants was considerably lower than the ratio of 92 for those in Shanghai. The median age was 29.6 years for males and 27.7 years for females in the Beijing sample compared to 20.0 and 22.6 years, respectively, in the Shanghai sample. In the Beijing sample 1/3 came from urban places and 2/3 were of rural origin. In contrast, in Shanghai 2/3 came from other urban locations. 1/3 of migrants in Beijing originated in Hebei, the province immediately adjoining the city. Most other temporary migrants came from the regions closest to Beijing. Migrants who stayed in Beijing's hotels cited business as their motivation: over half the men and almost 1/3 of the women. Multiple logistic analysis using pooled data from both cities suggest that under 10% of migrants migrated for work, but far larger percentages came to visit or to stay. 25-44 year olds, males, and nonrelatives cited mainly the economic motive. Children 5-14 years old, immediate relatives, and those from nonadjacent provinces came to the cities to live, while older people (65-69 years old), not immediate relatives, urban persons, and those from adjacent provinces were more likely to come for visits. Among people 25-29 years old over half were expected to come to Beijing to work, while this was true for only 18% of migrants in Shanghai. Temporary migrants living in Beijing had been there for 34 months, while those in Shanghai had an estimated duration of residence of only 26 months.

    There are many issues regarding the use of real patients in objective structured clinical examinations (OSCEs). In dermatology OSCE stations, standardised patients (SPs) with clinical photographs are often used. Temporary transfer tattoos can potentially simulate skin lesions when applied to an SP. This study aims to appraise the use of temporary malignant melanoma tattoos within an OSCE framework. Within an 11-station OSCE, a temporary malignant melanoma tattoo was developed and applied to SPs in a 'skin lesion' OSCE station. A questionnaire captured the opinions of the candidate, SP and examiners, and the degree of perceived realism of each station was determined. Standard post hoc OSCE analysis determined the psychometric reliability of the stations. The response rates were 95.9 per cent of candidates and 100 per cent of the examiners and SPs. The 'skin lesion' station achieved the highest realism score compared with other stations: 89.0 per cent of candidates felt that the skin lesion appeared realistic; only 28 per cent of candidates had ever seen a melanoma before in training. The psychometric performance of the melanoma station was comparable with, and in many instances better than, other OSCE stations. Transfer tattoo technology facilitates a realistic dermatology OSCE station encounter. Temporary tattoos, alongside trained SPs, provide an authentic, standardised and reliable experience, allowing the assessment of integrated dermatology clinical skills. © 2013 John Wiley & Sons Ltd.

  15. Factors underlying observed injury rate differences between temporary workers and permanent peers.

    PubMed

    2017-10-01

    Temporary workers face increased risk of injury as compared to permanent workers in similar occupations. This study explores the role played by several potential risk factors. Injured temporary and permanent workers, matched by industry, tenure and demographic characteristics, were interviewed to isolate the association of temporary employment with several injury risk factors. Temporary workers had higher workers' compensation claims rates than their permanent worker-peers. In interviews temporary workers a reported a lower frequency of exposure to hazards. However, they also reported being less likely to be equipped to cope with hazards by such countermeasures as experience screening, safety training and task control. Policies are needed to improve screening and training of temporary workers to assigned tasks, to discourage job-switching, to improve temporary workers' hazard awareness, to protect their right to report unsafe conditions. The responsibilities of agencies and host employers for ensuring the safety of their temporary workers need clarification in regulatory policy. © 2017 Wiley Periodicals, Inc.

    Transrectal stoma placement is considered the standard technique for positioning a stoma. A prospective series using a novel method of lateral pararectal stoma placement recently revealed a remarkably low stoma herniation rate. A randomized trial was conducted to compare the lateral pararectal with the transrectal stoma position with regard to parastomal herniation, stoma-related morbidity and quality of life. Adult patients undergoing elective placement of a temporary loop ileostomy were eligible for inclusion. Patients were intra-operatively randomized to undergo either a lateral pararectal or a transrectal ileostomy. The primary end-point was the rate of parastomal herniation. Secondary end-points included other stoma-related complications and quality of life. Sample size calculation resulted in 54 patients having to be analysed to detect a difference of parastomal herniation of 30% with an 80% power and a 5% significance level. The trial was registered with the German Clinical Trials Register (registration number DRKS00003534). Between April 2012 and April 2014, 30 patients were randomized to each group. The incidence of parastomal herniation did not differ between the lateral pararectal (5 of 27) and the transrectal group (4 of 29; P = 0.725). There was also no significant difference regarding other stoma-related complications and the EORTC quality of life scales C30 and CR29. The incidence of parastomal herniation and other stoma-related complications did not differ between the groups. However, due to the limited sample size a small difference in favour of one of the two stoma placement techniques cannot be entirely ruled out.

  8. Clinical results of treatment using a modified K-wire tension band versus a cannulated screw tension band in transverse patella fractures

    Tan, Honglue; Dai, Pengyi; Yuan, Yanhao

    2016-01-01

    Abstract It was a retrospective case–control study. The aim of this study was to explore the clinical efficacy and complication of treatment using a modified Kirschner wire tension band (MKTB) or a cannulated screw tension band (CSTB) in transverse patellar fractures. In total, 55 patients with transverse patellar fractures were retrospectively reviewed and divided into 2 groups according to the surgical technique: 29 patients were in the MKTB group and 26 patients in the CSTB group. Bǒstman's clinical grading scale, including range of movement (ROM), pain, ability to work, atrophy of quadriceps femoris, assistance in walking, effusion, giving way, and stair-climbing, was used to evaluate the clinical results. Complications including painful hardware, implant loosening or breakage, and bone nonunion were also assessed. Both groups were evaluated at the final follow-up before removing implant in the MKTB group. The Bǒstman's score of ROM, pain, atrophy of quadriceps femoris, and effusion were all higher in the CSTB group than in the MKTB group (P < 0.05). Twelve patients in the MKTB group underwent implant removal, and the score of ROM, pain, and effusion were higher than before removing implant (P < 0.05), but there was no difference compared to the CSTB group (P > 0.05). Seventeen patients achieved excellent results, 9 had good results, and 3 reported fair results in the MKTB group; the CSTB group had excellent results in 22 patients and good results in 4 patients, showing a significant difference in the excellent rate between the 2 groups (P = 0.021). Total Bǒstman scores in the MKTB and CSTB groups (26.96 ± 4.47 and 29.42 ± 1.47, respectively) were significantly different (P = 0.01). Total scores in the MKTB group after removing implant were higher than those before removing implant (P = 0.001), and similar to those in the CSTB group (P = 0.224). Eleven patients in the MKTB group reported painful hardware, including 4

  9. Large capacity temporary visual memory

    PubMed Central

    Endress, Ansgar D.; Potter, Mary C.

    2014-01-01

    Visual working memory (WM) capacity is thought to be limited to three or four items. However, many cognitive activities seem to require larger temporary memory stores. Here, we provide evidence for a temporary memory store with much larger capacity than past WM capacity estimates. Further, based on previous WM research, we show that a single factor — proactive interference — is sufficient to bring capacity estimates down to the range of previous WM capacity estimates. Participants saw a rapid serial visual presentation (RSVP) of 5 to 21 pictures of familiar objects or words presented at rates of 4/s or 8/s, respectively, and thus too fast for strategies such as rehearsal. Recognition memory was tested with a single probe item. When new items were used on all trials, no fixed memory capacities were observed, with estimates of up to 9.1 retained pictures for 21-item lists, and up to 30.0 retained pictures for 100-item lists, and no clear upper bound to how many items could be retained. Further, memory items were not stored in a temporally stable form of memory, but decayed almost completely after a few minutes. In contrast, when, as in most WM experiments, a small set of items was reused across all trials, thus creating proactive interference among items, capacity remained in the range reported in previous WM experiments. These results show that humans have a large-capacity temporary memory store in the absence of proactive interference, and raise the question of whether temporary memory in everyday cognitive processing is severely limited as in WM experiments, or has the much larger capacity found in the present experiments.

    Retrospective evaluation of the reasons for complications caused by the placement of temporary vena cava filters. Retrospective analysis of 9 complications in 6 implanted temporary (2 anthéor TC-, 4 Filcard RF 02-Filter) and 6 retrievable vena cava filters (1 Dil-, 5 FCP 2002-Filter). We observed 7 filter thromboses and two severe infections. 5 filter thromboses occurred in temporary filters, two filter thromboses and two infections occurred in facultative temporary filters. The main complications of temporary vena cava filters, like filter thrombosis and infection, were associated with the fixation mechanism of the filter. Our results indicate that facultative temporary vena cava filters without a permanent percutaneous retrieval system seem to be the safer system.

    The high proportion of diabetic patients is partly responsible for the high frequency of chronic renal failure in Reunion. The confection and maintenance of an arterio-venous fistule is a major problem in those patients. We report herein our experience with temporary vascular access by internal jugular vein catherization with subcutaneous tunnelization using silastic catheters. The mean duration of utilisation of these accesses is 107 days for diabetic patients and 98 days for nondiabetic patients. The major complication observed is sepsis (18.36%). Diabetes mellitus which represent a traditional risk factor does not seem to be responsible here, the climatic and hygienic conditions prevailing in this part of the world could be a contributing factor. Nevertheless, we find the utilisation of these catheters a suitable solution during the waiting period because it is an easy operation, of the good quality of the material used and the comfort brought to the patient.

  1. Conversion from temporary external fixation to definitive fixation: shaft fractures.

    PubMed

    Dougherty, Paul J; Silverton, Craig; Yeni, Yener; Tashman, Scott; Weir, Robb

    2006-01-01

    Temporary external fixation is the most common method of initial stabilization of diaphyseal fractures in forward surgical hospitals. Once the patient arrives at a stable environment, usually the United States, the fracture is managed with intramedullary nailing, small-pin external fixation, or a modified external fixator. Future research should be directed toward improving methods of care. It is not precisely known when is the best time to convert to definitive fixation without increasing the risk of infection. The risk factors leading to infection and nonunion are not well-established, making that determination even more difficult. Clinical studies of a suitable size should provide insight into these problems. Although temporary external fixation is commonly used, an optimal construct has not been determined. Data from studies of in vivo fracture-site motion after application of the temporary external fixator should be compared with biomechanical testing of similar constructs. These data could be used to recommend optimal temporary external fixation constructs of tibia, femur, and humerus fractures using currently available devices as well as to provide groundwork for the next generation of fixators.

  2. Effects of acidification on algal assemblages in temporary ponds

    SciTech Connect

    Glackin, M.E.; Pratt, J.R.

    1994-12-31

    Atmospheric deposition monitoring in Pennsylvania has characterized a steep gradient of acidic ion depositions across the north-central portion of the state. This study evaluated acidification effects on the composition of algal assemblages in temporary ponds in two forested areas exposed to atmospheric deposition that varied in degree of acidity. Artificial substrates were used to sample and compare the algal assemblages in the two areas. Colonized communities were also transplanted to lower pH ponds to observe changes in species composition. A laboratory microcosm experiment manipulating pH was conducted to reduce the variables that differed between the two areas. Fewer algal taxa were present in lower pH ponds, on colonized substrates after transplant to lower pH ponds, and in lower pH laboratory treatments. Species composition was altered in the lower pH conditions. Most taxa that were excluded from the lower pH ponds naturally also did not survive when experimentally introduced to those conditions. These results suggest that acidification of temporary ponds can alter the structure of algal communities. There is interest in a possible link between acid deposition and reports of worldwide declines in amphibian populations. Algae are an important food source for larval amphibians, such as the wood frog, which require temporary ponds to breed. Changes in algal species composition could potentially impact the temporary pond and forest ecosystem.

    First metatarsophalangeal joint (MTPJ) arthrodesis remains a commonly used and reliable procedure for a variety of pathologies of the first MTPJ. Many costly fixation constructions have been described to achieve union with first MTPJ arthrodesis. We hypothesized that the incidence of union would be the same for both buried Kirchner (K)-wire and solid crossed screw fixation with immediate weightbearing. To test this hypothesis, we retrospectively reviewed first MTPJ fusions performed by the senior author (C.A.C.) during a 6-year period and compared the incidence of union. Only patients who were immediately weightbearing in a surgical shoe and had undergone first MTPJ arthrodesis using K-wires or crossed screws were included. All patients had undergone incorporation of their sesamoids into the fusion. A total of 97 feet in 89 patients met the inclusion criteria. Of the 97 first MTPJ fusions, 48 (49.5%) had buried K-wire fixation and 49 (50.5%) crossed screw fixation. The mean age was 62 (range 41 to 75) years in the K-wire group and 60 (range 22 to 73) years in the crossed screw group. The mean follow-up period was 12.4 months in the K-wire group and 12.9 months in the crossed screw group. The rate of union in the K-wire group was 98% (1 nonunion) and the rate of union in the crossed screw group was 96% (2 nonunions). The 2 groups demonstrated similar high rates of fusion with immediate weightbearing, suggesting that less costly fixation is acceptable and effective for uncomplicated first MTPJ fusion.

    The insertion of a temporary pacemaker can be a lifesaving procedure in the emergency setting. This is an observational monocentric study comparing echocardiography-guided temporary pacemaker via the right internal jugular vein to standard fluoroscopy-guided temporary pacemaker via the femoral vein; the procedure was tested for noninferiority. Patients needing urgent pacing were consecutively enrolled. Primary efficacy endpoints were time to pacing and need for catheter replacement. Primary safety endpoint was a composite outcome of overall complications. One hundred and six patients (77 ± 10 years) were enrolled: 53 underwent echocardiographic-guided and 53 fluoroscopy-guided temporary pacemaker. Baseline characteristics of the two groups of treatment were similar. Time to pacing was shorter in the echocardiography-guided than in the fluoroscopy-guided group (439 ± 179 vs. 716 ± 235 s; P<0.0001; power 100%). During the pacing (54 ± 35 h), there was a higher incidence of pacemaker malfunction in the fluoroscopy-guided group [15 vs. 3 patients; odds ratio (OR) 6.5, confidence interval (CI) 95% 1.9-29.7, P<0.001; power 5.7%] and there was a significantly lower incidence of complications in the echocardiography-guided temporary pacemaker group (6 vs. 22 patients; OR 0.18, CI 95% 0.06-0.49, P<0.001; echocardiography-guided temporary pacemaker events rate 0.1929 vs. fluoroscopy-guided temporary pacemaker events rate 1.398 per 100 person-hours paced, P<0.0001). In the standard group there was one death attributable to a temporary pacemaker complication (sepsis). Echocardiography-guided temporary pacemaker is a well-tolerated procedure that could allow reliable insertion of a temporary pacemaker; therefore, it is a well-tolerated option in an emergency setting and in hospitals where fluoroscopy is not available.

    Despite intensive monitoring, temporary emigration from the sampling area can induce bias severe enough for managers to discard life-history parameter estimates toward the terminus of the times series (terminal bias). Under random temporary emigration unbiased parameters can be estimated with CJS models. However, unmodeled Markovian temporary emigration causes bias in parameter estimates and an unobservable state is required to model this type of emigration. The robust design is most flexible when modeling temporary emigration, and partial solutions to mitigate bias have been identified, nonetheless there are conditions were terminal bias prevails. Long-lived species with high adult survival and highly variable non-random temporary emigration present terminal bias in survival estimates, despite being modeled with the robust design and suggested constraints. Because this bias is due to uncertainty about the fate of individuals that are undetected toward the end of the time series, solutions should involve using additional information on survival status or location of these individuals at that time. Using simulation, we evaluated the performance of models that jointly analyze robust design data and an additional source of ancillary data (predictive covariate on temporary emigration, telemetry, dead recovery, or auxiliary resightings) in reducing terminal bias in survival estimates. The auxiliary resighting and predictive covariate models reduced terminal bias the most. Additional telemetry data was effective at reducing terminal bias only when individuals were tracked for a minimum of two years. High adult survival of long-lived species made the joint model with recovery data ineffective at reducing terminal bias because of small-sample bias. The naïve constraint model (last and penultimate temporary emigration parameters made equal), was the least efficient, though still able to reduce terminal bias when compared to an unconstrained model.

    During long-term anticoagulation in atrial fibrillation, temporary interruptions (TIs) of therapy are common, but the relationship between patient outcomes and TIs has not been well studied. We sought to determine reasons for TI, the characteristics of patients undergoing TI, and the relationship between anticoagulant and outcomes among patients with TI. In the Rivaroxaban Once Daily, Oral, Direct Factor Xa Inhibition Compared With Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation (ROCKET AF), a randomized, double-blind, double-dummy study of rivaroxaban and warfarin in nonvalvular atrial fibrillation, baseline characteristics, management, and outcomes, including stroke, non-central nervous system systemic embolism, death, myocardial infarction, and bleeding, were reported in participants who experienced TI (3-30 days) for any reason. The at-risk period for outcomes associated with TI was from TI start to 30 days after resumption of study drug. In 14 236 participants who received at least 1 dose of study drug, 4692 (33%) experienced TI. Participants with TI were similar to the overall ROCKET AF population in regard to baseline clinical characteristics. Only 6% (n=483) of TI incidences involved bridging therapy. Stroke/systemic embolism rates during the at-risk period were similar in rivaroxaban-treated and warfarin-treated participants (0.30% versus 0.41% per 30 days; hazard ratio [confidence interval]=0.74 [0.36-1.50]; P=0.40). Risk of major bleeding during the at-risk period was also similar in rivaroxaban-treated and warfarin-treated participants (0.99% versus 0.79% per 30 days; hazard ratio [confidence interval]=1.26 [0.80-2.00]; P=0.32). TI of oral anticoagulation is common and is associated with substantial stroke risks and bleeding risks that were similar among patients treated with rivaroxaban or warfarin. Further investigation is needed to determine the optimal management strategy in patients with atrial fibrillation

    Radiofrequency (RF) technology has improved detection of retained surgical sponges with a reported 100% sensitivity and specificity. However, the potential for interactions of the RF signals emitted by the detection system with cardiac implantable electronic devices (CIEDs) or temporary pacemakers may limit its use in those patients with these devices. This study investigated whether RF detection technology causes interference or clinically significant changes in the programmed settings of implanted pacemakers and defibrillators or temporary epicardial pacemakers. Fifty patients who were scheduled either for CIED removal or placement of a temporary epicardial pacemaker (at the time of open heart surgery) were recruited for this study. Device settings and measurements from separate interrogations before and after scanning with the RF detection system were compared. For the temporary pacemakers, we observed for any changes in hemodynamics or signs of pacing interference. Twenty (40%) pacemakers, 20 (40%) implantable cardioverter defibrillators, and 10 (20%) temporary pacemakers were analyzed in this study. During scanning, no signal interference was detected in any permanent device, and there were no significant changes in programmed settings after scanning with the RF detection system. However, pacing inhibition was detected with temporary pacing systems when programmed to a synchronous mode (DDD). RF detection technology can be safely used to scan for retained surgical sponges in patients with permanent CIEDs and temporary pacemakers set to asynchronous mode. © 2016 Wiley Periodicals, Inc.

    A completely new Administrative Procedure for temporary shielding was developed for use at Commonwealth Edison`s six nuclear stations. This procedure promotes the use of shielding, and addresses industry requirements for the use and control of temporary shielding. The importance of an effective procedure has increased since more temporary shielding is being used as ALARA goals become more ambitious. To help implement the administrative procedure, a personal computer software program was written to incorporate the procedural requirements. This software incorporates the useability of a Windows graphical user interface with extensive help and database features. This combination of a comprehensive administrative procedure and user friendly software promotes the effective use and management of temporary shielding while ensuring that industry requirements are met.

  20. Estimation of temporary emigration in male toads

    Muths, E.; Scherer, R. D.; Corn, P.S.; Lambert, B.A.

    2006-01-01

    Male boreal toads (Bufo boreas) are thought to return to the breeding site every year but, if absent in a particular year, will be more likely to return the following year. Using Pollock's robust design we estimated temporary emigration (the probability a male toad is absent from a breeding site in a given year) at three locations in Colorado, USA: two in Rocky Mountain National Park and one in Chaffee County. We present data that suggest that not all male toads return to the breeding site every year. Our analyses indicate that temporary emigration varies by site and time (for example, from 1992 to 1998, the probability of temporary emigration ranged from 10% to 29% and from 3% to 95% at Lost Lake and Kettle Tarn, respectively). Although the results provide weak evidence that males are more likely to return after a year's hiatus, a general pattern of state-dependent temporary emigration was not supported. We also hypothesized relationships between temporary emigration and a number of weather variables. While some competitive models included weather covariates, imprecise and variable estimates of the effects of these covariates precluded fully defining their impact on temporary emigration. ?? 2006 by the Ecological Society of America.

    Classic self-curing temporary cements obstruct the translucence of provisional restorations. New dual-cure esthetic temporary cements need investigation and comparison with classic cements to ensure that they are equally retentive and provide adequate translucence. The objective is to analyze by means of traction testing in a in vitro study the retention of five temporary cements. Ten molars were prepared and ten provisional resin restorations were fabricated using CAD-CAM technology (n=10). Five temporary cements were selected: self-curing temporary cements, Dycal (D), Temp Bond (TB), Temp Bond Non Eugenol (TBNE); dual-curing esthetic cements Temp Bond Clear (TBC) and Telio CS link (TE). Each sample underwent traction testing, both with thermocycling (190 cycles at 5-55º) and without thermocycling. TE and TBC obtained the highest traction resistance values. Thermocycling reduced the resistance of all cements except TBC. The dual-cure esthetic cements tested provided optimum outcomes for bonding provisional restorations. Key words:Temporary dental cements, cements resistance.

  3. Temporary restorations: advantages and disadvantages.

    PubMed

    Waerhaug, J

    1980-04-01

    The reaction of tissue to temporary restorations was studied in four young dogs and four young monkeys. A total of 56 cavities were prepared and filled with gutta percha, self-curing acrylic resin, or zinc oxide and eugenol cement. Attempts were made to finish the preparations at the deepest point of the existing clinical pocket, which invariably was found to coincide with the cemento-enamel junction. All the animals had the teeth on the left side brushed every day. The observation periods varied between 13 and 283 days. Immediately before the animals were killed by an overdose of Nembutal, the presence or absence of gingivitis was recorded. A series of sections were cut in the area of the cavity, as well as just outside it. The following observations were made: Examination of the sections from outside the cavities verified that the preparations had been made in pockets with soft walls made up of the junctional epithelium. The cavities ended shortly above the cemento-enamel junction (Figs. 3, 4, 6, and 8) or below it (Figs. 1, 2, 5, 7, and 9 to 11). The adaptation of the fillings was never perfect in all parts of the cavity at the same time. The pocket epithelium was regenerated within 13 days. Plaque formation first started in the open spaces between the preparation and the fillings. Subsequently, the plaque spread over the surfaces of the fillings and eventually over the tooth surface below them. The fillings invariably induced submarginal gingivitis, even in the absence of plaque. Presence of plaque exacerbated the inflammatory reaction, but the loss of attachment was limited to less than 0.2 mm as long as the plaque was confined to the fillings. Significant loss of attachment was always associated with apical growth of the subgingival plaque. The submarginal gingivitis was not manifested clinically if the fillings were brushed daily, because vigorous tooth brushing had an effect as far as 0.7 mm below the gingival margin.

    1997-05-01

    The marginal seal of four temporary filling materials in endodontic access cavities was examined in vitro after thermocycling and mechanical loading using dye penetration tests and a quantitative marginal analysis of replicas in the SEM. Class I cavities were prepared in 44 extracted human molars and filled either with Cavit, Kalsogen, IRM, or TERM. After setting the reaction and thermocycling procedure, Cavit showed less microleakage in the dye penetration test and fewer marginal crevices in the quantitative marginal analysis. After loading, two Cavit fillings collapsed into the endodontic cavity. The marginal conditions of TERM were comparable to Cavit after thermocycling and mechanical loading. Kalsogen and IRM restorations demonstrated significantly increased microleakage and a higher percentage of marginal crevices after thermocycling and loading. In contrast to dye penetration tests, the effects of different factors on the marginal integrity of temporary fillings can be examined with the replica technique and quantitative marginal analysis.

    Animal research has shown that antioxidants can provide significant protection to the cochlea from traumatic noise exposure with some benefit when given after the exposure. Similar results in humans would have a significant impact on both prevention and treatment of noise-induced hearing loss. The current study evaluates the effectiveness of N-acetylcysteine (NAC) on temporary threshold shift (TTS) by using both behavioral and physiological measures. Sixteen healthy, normal-hearing subjects were given NAC or a placebo prior to exposure to a 10-min, 102-dB narrow-band noise, centered at 2 kHz. This exposure was designed to induce a 10-15-dB TTS. Following the noise exposure, pure-tone thresholds (Bekesy) and transient-evoked otoacoustic emissions (TEOAE) were measured for 60 min to monitor the effects of NAC on TTS recovery. Postexposure measures were compared to baseline data. [Work supported by American BioHealth Group.

    Knutson, Kevin J; Berzins, David W

    2013-08-01

    Corrosion of orthodontic miniscrews or temporary anchorage devices (TADs) has been proposed as a contributor to inflammation, which in turn is a factor in the clinical success of miniscrews. The purpose of this study was to measure the electrochemical properties of orthodontic miniscrews in artificial saliva with and without fluoride. The corrosion properties of three miniscrew products (VectorTAS, Ormco Corp.; Unitek TAD, 3M Unitek; and Through-Hole Screw, American Orthodontics) were tested in an artificial saliva (Fusayama-Meyer) with (1500 ppm) or without fluoride (n = 10/product/solution). Open circuit potential (OCP), polarization resistance (R p), and corrosion current (I corr) were measured and statistically analysed with the Friedman/Tukey least significant difference tests. No significant differences (P > 0.05) between miniscrews with regard to OCP, R p, and I corr were found except that the American Orthodontics miniscrews had a significantly (P < 0.05) more noble OCP compared to the others. Incorporation of 1500 ppm fluoride in the artificial saliva significantly (P < 0.001) lowered the OCP, reduced the polarization resistance, and increased the corrosion current of each miniscrew product. Few differences existed in the electrochemical properties of miniscrews from the three different manufacturers; however, exposure to fluoride was detrimental to the corrosion properties of all miniscrews.

    Screen-printed sensor for measuring human pulse was designed and first tests using a demonstrator device were conducted. Various materials and sensors' set ups were compared and the results are presented as the starting point for fabrication of fully functional device. As a screen printing substrate, commercially available temporary tattoo paper was used. Using previously developed nanomaterials-based pastes design of a pressure sensor was printed on the paper and attached to the epidermis. Measurements were aimed at determining sensors impedance constant component and its variability due to pressure wave caused by the human pulse. The constant component was ranging from 2kΩ to 6kΩ and the variations of the impedance were ranging from +/-200Ω to +/-2.5kΩ, depending on the materials used and the sensor's configuration. Calculated signal-to-noise ratio was 3.56:1 for the configuration yielding the highest signal level. As the device's net impedance influences the effectiveness of the wireless communication, the results presented allow for proper design of the sensor for future health-monitoring devices.

  4. The effects of temporary agency work contract transitions on well-being.

    2016-11-01

    Theoretical and empirical research has provided mixed arguments and evidence for the effects of temporary agency work on workers' well-being. This study aims to go one critical step further by comparing the workplace and general well-being of workers who continue to have this employment status with others who obtain a direct contract and others who remain unemployed. Temporary agency workers longitudinal data (n = 289) was used, and three groups were compared: (1) maintaining a temporary agency contract (n = 187), (2) obtaining a direct contract (n = 57), and (3) remaining unemployed (n = 45). Covariance analyses adjusted for background variables showed that those who obtained a direct contract experienced a decrease in job insecurity but experienced an increase in job demands, while those who continued to have a temporary agency contract maintained these job conditions. However, in terms of workplace well-being, the temporary agency contract was not found to be more detrimental than a direct contract, but in terms of life satisfaction, unemployment was found to be more detrimental than other transitions. A temporary agency contract does not have an inevitable negative effect on workers' well-being.

    Objective: To compare PermeaDerm to first temporary biosynthetic skin substitute (Biobrane, cleared by the Food and Drug Administration in 1979). Methods: Different temporary skin substitutes (Biobrane, PermeaDerm, and PermeaDerm derivatives) were tested for physical differences, impact on healing wounds, inflammatory response, and ability to allow adequate growth of dermal fibroblasts and mesenchymal stem cells without accumulation of excessive scar-forming myofibroblasts. Proliferation of fibroblasts and stem cells on various skin substitutes was measured, and myofibroblast marker accumulation was evaluated by the expression of α-smooth muscle actin and fibronectin. Fibroblast migration was measured by tracking viable cells with MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] dye. Results: In vivo testing shows PermeaDerm works well as a temporary skin substitute, performing better than Biobrane with respect to inflammation and fluid accumulation. Tissue culture techniques revealed that cells on PermeaDerm grow in a more uniform fashion and migrated to a greater extent than cells on Biobrane. Furthermore, cells grown in the presence of PermeaDerm expressed lower levels of the myofibroblast markers α-smooth muscle actin and fibronectin than cells grown on Biobrane. Conclusion: PermeaDerm with variable porosity possesses all attributes and properties known to be important for a successful temporary skin substitute and enables the clinician to control porosity from essentially zero to what the wound requires. The ability of the clinician to minimize wound desiccation without fluid accumulation is related to the reduction of punctate scarring. PMID:26229573

    Temporary disability is the condition that workers face when, as the result of illness (common or professional) or accident (work-related or not), they are temporarily prevented from performing their work and require health care. The management of temporary disability is a medical act that involves (in addition to a complex clinical assessment) obvious social, occupational and financial connotations and requires continuing medical follow-up from doctors, as well as responses to medical-legal conflicts. The regulatory framework on the subject is extensive in the Spanish setting and highly diverse in the European setting. Beyond the regulatory framework, the repercussions of temporary disability are self-evident at all levels. Although determining temporary disability is a common medical act for practicing physicians, it is not exempt from risks or difficulties arising from the assessment itself and the characteristics of practicing medical care. Established medical-legal conflicts include the processing of health data and the requirements for transferring information related to workers' temporary disability to their company's medical services. The interest and usefulness demonstrated by the data obtained from forensic medicine for public health require the incorporation of these data into general healthcare information, as it could be essential to the surveillance of worker health. The recommendations established by medical societies, as good practice guidelines, are especially useful in this type of conflict. Copyright © 2014 Elsevier España, S.L. All rights reserved.

    Contact sensitization to natural henna (Lawsonia inermis) long used as a skin dye in powder or paste form has rarely, if ever, been observed. Recently a number of anaphylactoid reactions to PPD contained in paints used for temporary tattoos have been described. The purpose of this article is to present 8 cases involving 4 children and 4 adults who developed contact dermatitis after temporary tattoo using "harkous" that contains no henna. The authors review the literature about temporary tattooing. "Harkous" is a mixture of nut gall and clove to which PPD is sometimes added. Many reports have described cases of contact dermatitis due to "black henna". Most of these cases have involved tourists returning from trips.

  8. Options for temporary mechanical circulatory support

    PubMed Central

    Saffarzadeh, Areo

    2015-01-01

    Temporary mechanical circulatory support (MCS) refers to a group of devices generally used for less than 30 days to maintain adequate organ perfusion by compensating for a failure of the pumping mechanism of the heart. The increased availability and rapid adoption of new temporary MCS strategies necessitate physicians to become familiar with devices placed both percutaneously and via median sternotomy. This review will examine the different options for commonly used temporary MCS devices including intra-aortic balloon pumps (IABPs), veno-arterial-extracorporeal membrane oxygenation (VA-ECMO), TandemHeart® (CardiacAssist, Pittsburg, PA, USA) Impella® and BVS 5000® (both Abiomed Inc., Danvers, MA, USA), CentriMag® and Thoratec percutaneous ventricular assist device (pVAD)® (both Thoratec Corporation, Pleasanton, CA, USA). A specific emphasis will be made to describe relevant mechanisms of action, standard placement strategies, hemodynamic effects, relevant contraindications and complications, and important daily management considerations.

  9. No cheers for temporary artificial hearts.

    PubMed

    Annas, G J

    1985-10-01

    The author continues his argument against the temporary artificial heart ("The Phoenix heart: what we have to lose," Hastings Center Report 1985 Jun; 15(3): 15-16) with an account of recipient Michael Drummond's experience at the University of Arizona in August 1985. Annas faults the University's informed consent procedure and labels its consent form "misleading, rudimentary, and confusing." He also questions why Drummond was assigned top priority for a human heart after he had received a temporary artificial one. Annas urges a moratorium on permanent artificial hearts because of their devastating effects on recipients, and on temporary devices because they may become permanent. He also argues that there is, as yet, no ethically acceptable way of allocating human hearts to those with artificial hearts, and that the expensive bridge-to-transplant procedure fails to increase the total number of lives saved by heart transplants.

  10. Need for adaptation: transformation of temporary houses.

    PubMed

    Wagemann, Elizabeth

    2017-02-14

    Building permanent accommodation after a disaster takes time for reasons including the removal of debris, the lack of available land, and the procurement of resources. In the period in-between, affected communities find shelter in different ways. Temporary houses or transitional shelters are used when families cannot return to their pre-disaster homes and no other alternative can be provided. In practice, families stay in a standard interim solution for months or even years while trying to return to their routines. Consequently, they adapt their houses to meet their midterm needs. This study analysed temporary houses in Chile and Peru to illustrate how families modify them with or without external support. The paper underlines that guidance must be given on how to alter them safely and on how to incorporate the temporary solution into the permanent structure, because families adapt their houses whether or not they are so designed.

  11. Refractive Changes after Removal of Anterior IOLs in Temporary Piggyback IOL Implantation for Congenital Cataracts

    2013-01-01

    Purpose To assess the refractive change and prediction error after temporary intraocular lens (IOL) removal in temporary polypseudophakic eyes using IOL power calculation formulas and Gills' formula. Methods Four consecutive patients (7 eyes) who underwent temporary IOL explantation were enrolled. Postoperative refractions calculated using IOL power calculation formulas (SRK-II, SRK-T, Hoffer-Q, Holladay, and the modified Gills' formula for residual myopia and residual hyperopia) were compared to the manifest spherical equivalents checked at 1 month postoperatively. Results The mean ages of temporary piggyback IOL implantation and IOL removal were 6.71 ± 3.68 months (range, 3 to 12 months) and 51.14 ± 18.38 months (range, 29 to 74 months), respectively. The average refractive error was -13.11 ± 3.10 diopters (D) just before IOL removal, and improved to -1.99 ± 1.04 D after surgery. SRK-T showed the best prediction error of 1.17 ± 1.00 D. The modified Gills' formula for myopia yielded a relatively good result of 1.47 ± 1.27 D, with only the variable being axial length. Conclusions Formulas to predict refractive change after temporary IOL removal in pediatric polypseudophakia were not as accurate as those used for single IOL implantation in adult eyes. Nonetheless, this study will be helpful in predicting postoperative refraction after temporary IOL removal. PMID:23543846

    Disaster has a negative impact on health conditions, especially on those of temporary housing residents. Health status has a close relationship with physical activity and performance. However, few reports have assessed physical performance among residents living in temporary housing. In this study, we compared physical capabilities between the elderly who evacuated to temporary housing and those who stayed in their own homes after the Great East Japan Earthquake. Subjects were recruited from those over 65 years of age who participated in the medical check-ups for temporary housing residents (TH group) or check-ups for residents of downtown areas (control group) in Soma City, Fukushima, in 2012. The subjects underwent grip strength, one-leg standing (OLS), and timed up and go tests (TUG). In total, 1890 participants were recruited. The TH group showed significantly stronger grip strength than that of the control group. On the other hand, the TH group showed weaker standing stability, according to decreased OLS and increased TUG scores. We revealed that standing stability was impaired among elderly temporary housing residents 1.5 years after the disaster. Disaster responders should take into account the health risks associated with living in temporary housing. PMID:26844168

  14. Temporary versus permanent group membership: how the future prospects of newcomers affect newcomer acceptance and newcomer influence.

    PubMed

    Rink, Floor A; Ellemers, Naomi

    2009-06-01

    Three studies examine how the future prospects of new group members affect newcomer acceptance and newcomer influence. In Study 1, participants anticipate accepting temporary newcomers less easily than permanent newcomers because they expect temporary newcomers to differ from the group. In Study 2, the effects of newcomer entry in three-person groups are examined. Results show that groups perceived temporary newcomers as more involved in a judgmental decision-making process than permanent newcomers. In Study 3, a hidden profile task confirms that temporary newcomers indeed shared more unique knowledge during discussions than permanent newcomers and that this enhanced the groups' decision quality. However, compared to permanent newcomers, temporary newcomers caused teams to experience more conflict and less group identification, illustrating the tension between innovative group performance and group cohesion. The results are discussed in light of the social identity perspective and research on minority influence.

  13. [Laparoscopic ventriculoperitoneal shunt with temporary external drainage for hydrocephalus: a comparison with conventional ventriculoperitoneal shunt].

    PubMed

    Chen, Jianfa; Liu, Changxu; Zhu, Hongsheng; Fu, Ming; Lin, Fulu; Liu, Jun; Xie, Kuilong; Li, Ping

    2012-12-01

    To investigate the clinical efficacy of laparoscopic ventriculoperitoneal shunt with temporary external drainage in the treatment of hydrocephalus. Fifty-two cases of hydrocephalus randomized into two groups to receive laparoscopic assisted ventriculoperitoneal shunt with temporary external drainage (19 male and 7 female patients) and conventional ventriculoperitoneal shunt (20 male and 6 female patients). The catheterization time in the abdominal cavity, release time of intracranial hypertension, average hospital stay, postoperative pains, and postoperative complications were compared between the two groups. Laparoscopic ventriculoperitoneal shunt with temporary external drainage was performed successfully in all the cases without intraoperative conversion to open surgery. Compared with the conventional ventriculoperitoneal shunt, laparoscopic ventriculoperitoneal shunt with temporary external drainage was associated with significantly shortened catheterization time in the abdominal cavity, release time of intracranial hypertension, and average hospital stay (P<0.01) as well as lowered postoperative pain score at 4, 8, 16, and 24 h after the operation. The pain scores at 48 and 72 h postoperatively were comparable between the two groups. During the follow-up 3 months, the patients receiving laparoscopic ventriculoperitoneal shunt were found to have significantly lower rates of peritoneal end obstruction and abdominal cavity infection than those having conventional shunt (3.8% vs 19.2%, P<0.01; 1.0% vs 23.1%, P<0.01). Laparoscopic ventriculoperitoneal shunt with temporary external drainage is feasible and produces better clinical therapeutic effect for management of hydrocephalus.

    In recent years, temporary work (TW) has increased in European countries due to the greater uncertainty in the economy. To compare the prevalence of non-specific musculoskeletal symptoms of the upper extremities (UEMSDs) and their main risk factors in blue-collar workers employed through temporary agencies (TW) and in those in permanent employment (PE). UEMSDs occurring during the preceding 7 days were assessed using a Nordic questionnaire completed by 1493 blue-collar workers randomly included in a surveillance programme for UEMSDs (171 in TW and 1322 in PE) in a large French region. Personal factors and work-related risk factors for UEMSDs were assessed by self-administered questionnaires. The prevalence of UEMSDs during the preceding 7 days did not significantly differ between workers in TW or PE. However, after adjustment for age and gender, TW had a higher risk of symptoms of the wrist/hand region (OR = 1.6, 95% CI 1.04-2.6). TW was characterized by higher exposure to paced work (OR = 2.0, 95% CI 1.4-3.0), repetitive work (OR = 2.3, 95% CI 1.6-3.4), awkward postures of the wrist (OR = 1.6, 95% CI 1.2-2.4) and intensive use of vibrating hand tools (OR = 1.7, 95% CI 1.1-2.3). Workers in TW suffered from a lack of autonomy (OR = 2.5, 95% CI 1.7-3.6) and skill discretion at work (OR = 2.0, 95% CI 1.3-3.1) more frequently, but there was no difference in relation to psychological demands of the task or social support. Temporary workers were more frequently exposed to working time constraints, repetitive work and biomechanical constraints of the wrist/hand region when compared to permanent workers and may represent a subpopulation at particularly high risk of UEMSDs.

    Hairdressers are occupationally and personally exposed to hair dye substances and adverse reactions from the skin are well known. Currently, little is known about personal exposure to hair dye ingredients and temporary black tattoos. To investigate hairdressers' professional and personal risk exposures and to compare the frequency of temporary tattoos among hairdressers and subjects from the general population. A questionnaire was sent to 1679 Copenhagen hairdressers and 1063 (63.3%) responded; 3471 subjects from the general population in Copenhagen were asked about temporary black tattoos. Of the female hairdressers, 38.3% had coloured hair within the previous week. Adverse skin reactions to own hair dye were reported in 29.5%. In the hairdresser population, no significant association was observed between self-reported adverse skin reactions to hair dye and having had a temporary black tattoo when adjusted for sex, age, and atopy. A total of 19.0% of hairdressers (43.5% of apprentices) and 6.3% of participants from the general population had ever had a temporary black tattoo performed at one point. There were no differences in frequency of eczema after temporary tattooing between hairdressers and subjects in the general population. Almost all hairdressers (99.2%) used gloves for hair colouring, 51% for high/low lighting, 39.6% for perming and 21.1% used gloves for shampooing. In conclusion, skin reactions to hair colour are frequent among Copenhagen hairdressers. Temporary black tattoos were more frequent among hairdressers than in a sample of the general population and increased with decreasing age.

  8. Treatment of spontaneous tumours by temporary local ligation

    PubMed Central

    Allen, Frederick M.; Kaplan, Martin M.; Meranze, David R.; Gradess, Morton

    1960-01-01

    Previous work in some human cases and in laboratory animals has indicated that temporary local ligation of spontaneous tumours has a selective destructive effect on these tumours, with only temporary inflammation resulting in normal tissues. In the experiments described in this paper, 49 spontaneous accessible tumours in dogs were treated by this method, with periods of ligation of from 4 to 11 hours. Success, as measured by selective necrosis of tumour tissue as compared with normal tissue, was achieved in 29 out of 41 benign tumours, including lipomas, angiomas, adenomas and mixed mammary tumours. Treatment failures were encountered in two cases each of papillomas and fibromas, six mixed mammary tumours and two testicular tumours. Total necrosis of tumour cells occurred in all eight malignant tumours encountered in this series. The outstanding feature was the specific destruction of tumour tissue by a bodily process without participation of any outside agent. Emphasis was placed on an adequate inflammatory response following temporary anoxia, although a precise definition of this inflammation could not be offered. Post-ligation bacterial multiplication, which may be expected to occur in necrotic tumour tissue, is considered to be a secondary effect rather than a possible primary cause of regression and disappearance of the tumour. If ligation treatment can be shown to be successful for a particular type of tumour, it may be possible to apply it to human patients for the treatment of areas not amenable to surgery. The results reported here warrant new experimental approaches to the study of neoplasms at the cellular level to define more precisely the anoxic and inflammatory processes involved in the selective lethal effect on tumour tissues; and the authors suggest that trials should be undertaken of combinations of chemotherapy or irradiation with ligation to reduce ligation time and extend the possible benefits.

  9. Allergic contact dermatitis from temporary henna tattoo.

    PubMed

    Jovanovic, Dragan L; Slavkovic-Jovanovic, Maja R

    2009-01-01

    Temporary henna tattooing has been very popular during recent years. Henna (Lawsonia inermis) is a plant from the Lythraceae family. For henna tattooing, henna dye is used. It is a dark green powder, made from the leaves of the plant, used for hair dyeing and body tattooing. Very often, para-phenylenediamine (PPD) is added to henna dye to make color blacker and to speed up dyeing. PPD may be a very potent contact sensitizer. We report a 9-year-old boy with allergic contact dermatitis due to temporary henna tattooing. Patch testing showed a positive reaction to PPD. After the treatment with topical corticosteroid and oral antihistamines, the lesion cleared with discrete residual hypopigmentation.

    2006-03-01

    The purpose of this study was to investigate the antibacterial properties of temporary fillings. The direct contact test (DCT) was used to evaluate the antibacterial properties of Revoltek LC, Tempit, Systemp inlay, and IRM. These were tested in contact with Streptococcus mutans and Enterococcus faecalis. The materials were examined immediately after setting, 1, 7, 14, and 30 days after aging in phosphate buffered saline (PBS). Statistical analysis included two-way ANOVA, one-way ANOVA, and Tukey multiple comparison. Systemp inlay, Tempit, and IRM exhibited antibacterial properties when in contact with S. mutans for at least 7 days, Tempit and IRM sustained this ability for at least 14 days. When in contact with E. faecalis Tempit and IRM were antibacterial immediately after setting, IRM sustained this ability for at least 1 day. Our study suggests that the difference in temporary filling materials may influence which microorganism will be able to invade the root canal system.

    A unilateral blindness after transnasal ethmoidectomy was diagnosed postoperatively while the patient was still in theatre. Exploration via an external approach was performed immediately, a haematoma was drained and the posteroir ethmoid artery was cauterized. This led to a recovery of vision. The temporary blindness was probably due to increased intraorbital pressure by the retrobulbar haematoma which led to stretching of and pressure on the optic nerve.

    The Editorial Board of the Journal of Endodontics has developed a literature-based study guide of topical areas related to endodontics. This study guide is intended to give the reader a focused review of the essential endodontic literature and does not cite all possible articles related to each topic. Although citing all articles would be comprehensive, it would defeat the idea of a study guide. This section will cover endodontic temporary restorations.

  13. Comparison of hardness of three temporary filling materials cured by two light-curing devices.

    Polymerization ability of light-curing devices can affect the light-cured material hardness. The purpose of the present study was to evaluate and compare the hardness of three temporary filling materials that had been light-cured by either a light emitting diode (LED) or a halogen light-curing unit. The temporary filling materials, First Fill, Voco Clip and Bioplic, were placed in wells in a Teflon plate. The 24 specimens of each material were divided into two groups (N.=12/group) for photo-activation by either of the two light-curing units. The LED or halogen device was applied for 40s to the top surface of each specimen. A Knoop hardness test was performed on the top and bottom surface of each specimen, with five measurements per specimen. The highest hardness values for both the LED and halogen treated groups were observed for First Fill and the lowest values were for Voco Clip in top and bottom surfaces. The hardness obtained for the three materials with the halogen unit were significantly higher than the values obtained with the LED unit in both surfaces (P<0.05). First Fill light-cured temporary material exhibited the highest hardness values on the top and bottom surfaces than Voco Clip and Bioplic temporary materials. The hardness of light-cured temporary filling materials can be affected by the type of light-curing unit.

  14. Career pathways for temporary workers: exploring heterogeneous mobility dynamics with sequence analysis.

    PubMed

    Fuller, Sylvia; Stecy-Hildebrandt, Natasha

    2015-03-01

    Because temporary jobs are time-delimited, their implications for workers' economic security depend not only on their current characteristics, but also their place in longer-term patterns of mobility. Past research has typically asked whether temporary jobs are a bridge to better employment or trap workers in ongoing insecurity, investigating this question by analyzing single transitions. We demonstrate that this approach is ill-suited to assessing the often more complex and turbulent employment patterns characteristic of temporary workers. Our analysis instead employs sequence methods to compare a representative sample of temporary workers' month-by-month mobility patterns through 8 potential (non)employment states over five years. We derive a typology of trajectories and describe their relative precariousness in relation to employment stability and wage and earnings levels and growth. While some of the pathways correspond quite closely to frameworks used by past research, others reveal new and important distinctions. Multinomial logit models reveal job, employer, and worker characteristics associated with different pathways. Age, gender, and type of temporary work stand out as important factors shaping subsequent mobility patterns.

    Microbial communities are responsible for the bulk of biogeochemical processing in temporary headwater streams, yet there is still relatively little known about how community structure and function respond to periodic drying. Moreover, the ability to sample temporary habitats can be a logistical challenge due to the limited capability to measure and predict the timing, intensity and frequency of wet-dry events. Unsurprisingly, published datasets on microbial community structure and function are limited in scope and temporal resolution and vary widely in the molecular methods applied. We compared environmental and microbial community datasets for permanent and temporary tributaries of two different North American headwater stream systems: Speed River (Ontario, Canada) and Parkers Creek (Maryland, USA). We explored whether taxonomic diversity and community composition were altered as a result of flow permanence and compared community composition amongst streams using different 16S microbial community methods (i.e., T-RFLP and Illumina MiSeq). Contrary to our hypotheses, and irrespective of method, community composition did not respond strongly to drying. In both systems, community composition was related to site rather than drying condition. Additional network analysis on the Parkers Creek dataset indicated a shift in the central microbial relationships between temporary and permanent streams. In the permanent stream at Parkers Creek, associations of methanotrophic taxa were most dominant, whereas associations with taxa from the order Nitrospirales were more dominant in the temporary stream, particularly during dry conditions. We compared these results with existing published studies from around the world and found a wide range in community responses to drying. We conclude by proposing three hypotheses that may address contradictory results and, when tested across systems, may expand understanding of the responses of microbial communities in temporary streams to

    Purpose: To evaluate the clot trapping capacity of different temporary vena cava filters in a vena cava model. Methods: A vena cava flow model was built using PVC tubing, a hemodialysis membrane and a pulsatile pump. Blood was imitated by a Dextran 40 solution. Five different temporary vena cava filters and two prototypes were tested using human thrombi. The mechanism of clot capture was observed. Results: Decreasing rank order according to decreasing percentage of clots captured for the 21-mm diameter vena cava model was Cook (C) > Angiocor (A) > Cordis (CD) > Antheor (TF-6) > DIL for thrombi with a diameter of 3 mm and A > C > CD > TF-6 > DIL for 5-mm thrombi. In a cava with diameter of 28 mm, decreasing rank order was C > CD = A > TF-6 > DIL and C > CD = A > DIL > TF-6 for 3- and 5-mm thrombi, respectively. Two new prototypes, the TF-8 and TF-10 filters, achieved better results than the TF-6 filter and were in most conditions comparable to the A and CD filters. In most cases, thrombi were trapped between filter and cava wall. Conclusion: The vena cava flow model demonstrates significant differences in rates of clot capture (range 22%-98%) depending on cava diameter, thrombus size, and filter type.

    There are numerous materials that are used as temporaries for inlay and onlay preparations while the permanent restoration is being made. This article looks at 2 types of temporary materials that were placed into inlay or onlay preparations by student dentists: a methylmethacrylate acrylic material (DuraLay Inlay Pattern Resin) and a visible light-cured (VLC) periodontal surgical dressing (Barricaid). The resilience and effectiveness of both products are compared and evaluated for use as temporary restorations in inlay or onlay preparations. The study found that use of the VLC periodontal dressing material offers a novel technique for a quick and efficient method to provide a temporary restoration for various inlay and onlay preparations.

    Background and purpose — For the treatment of leg-length discrepancies (LLDs) of between 2 and 5 cm in adolescent patients, several epiphyseodesis options exist and various complications have been reported. We reviewed the 8- to 15-year outcome after temporary epiphyseodesis in patients with LLD. Patients and methods — 34 children with LLD of up to 5 cm were included in the study. Mean age at epiphyseodesis was 12.8 (10–16) years. Temporary epiphyseodesis was performed with Blount staples or 8-plates. The LLD was reviewed preoperatively, at the time of implant removal, and at follow-up. Every child had reached skeletal maturity at follow-up. Long-standing anteroposterior radiographs were analyzed with respect to the mechanical axis and remaining LLD at the time of follow-up. Possible complications were noted. Results — The mean LLD changed from 2.3 (0.9–4.5) cm to 0.8 (–1.0 to 2.6) cm at follow-up (p < 0.001). 21 patients had a final LLD of < 1 cm, and 10 had LLD of < 0.5 cm. At the time of follow-up, in 32 patients the mechanical axis crossed within Steven’s zone 1. No deep infections or neurovascular lesions were seen. 4 implant failures occurred, which were managed by revision. Interpretation — Temporary epiphyseodesis is an effective and safe option for the treatment of LLD. The timing of the procedure has to be chosen according to the remaining growth, facilitating a full correction of the LLD. If inaccurate placement of staples is avoided, substantial differences between the mechanical axes of both legs at skeletal maturity are rare. PMID:25191935

  19. Strategic planning for post-disaster temporary housing.

    2007-12-01

    Temporary housing programmes suffer from excessively high cost, late delivery, poor location, improper unit designs and other inherent issues. These issues can be attributed in part to a prevalence of ad hoc tactical planning, rather than pre-disaster strategic planning, for reconstruction undertaken by governments and non-governmental organisations (NGOs) in the chaotic post-disaster environment. An analysis of the process and outcomes from six case studies of temporary housing programmes after disasters in Turkey and Colombia in 1999, Japan in 1995, Greece in 1986, Mexico in 1985, and Italy in 1976 yields information about the extent to which strategic planning is employed in temporary housing programmes, as well as common issues in temporary housing. Based on an understanding of these common issues, this paper proposes a framework for strategic planning for temporary housing that identifies organisational designs and available resources for temporary housing before the disaster, but allows modifications to fit the specific post-disaster situation.

    ABSTRACT Incorporation of antifungals in temporary denture soft liners has been recommended for denture stomatitis treatment; however, it may affect their properties. Objective: To evaluate the porosity of a tissue conditioner (Softone) and a temporary resilient liner (Trusoft) modified by minimum inhibitory concentrations (MICs) of antifungal agents for Candida albicans biofilm. Material and Methods: The porosity was measured by water absorption, based on exclusion of the plasticizer effect. Initially, it was determined by sorption isotherms that the adequate storage solution for specimens (65×10×3.3 mm) of both materials was 50% anhydrous calcium chloride (S50). Then, the porosity factor (PF) was calculated for the study groups (n=10) formed by specimens without (control) or with drug incorporation at MICs (nystatin: Ny-0.032 g, chlorhexidine diacetate: Chx-0.064 g, or ketoconazole: Ke-0.128 g each per gram of soft liner powder) after storage in distilled water or S50 for 24 h, seven and 14 d. Data were statistically analyzed by 4-way repeated measures ANOVA and Tukey's test (α=.05). Results: Ke resulted in no significant changes in PF for both liners in water over 14 days (p>0.05). Compared with the controls, Softone and Trusoft PFs were increased at 14-day water immersion only after addition of Ny and Chx, and Chx, respectively (p<0.05). Both materials showed no significant changes in PF in up to 14 days of S50 immersion, compared with the controls (p>0.05). In all experimental conditions, Softone and Trusoft PFs were significantly lower when immersed in S50 compared with distilled water (p<0.05). Conclusions: The addition of antifungals at MICs resulted in no harmful effects for the porosity of both temporary soft liners in different periods of water immersion, except for Chx and Ny in Softone and Chx in Trusoft at 14 days. No deleterious effect was observed for the porosity of both soft liners modified by the drugs at MICs over 14 days of S50 immersion

    There has not been a comprehensive examination to date of peritoneal dialysis (PD) outcomes after temporary haemodialysis (HD) transfer for peritonitis. The study included all incident Australian patients who experienced peritonitis between 1 October 2003, and 31 December 2011, using Australia and New Zealand Dialysis and Transplant Registry data. Patients were grouped into three categories: Interim HD, Permanent HD and Never HD based on HD transfer status after the first peritonitis. The independent predictors of HD transfer and subsequent return to PD were determined by multivariable, multilevel mixed-effects logistic regression analysis. Matched case-control analyses were performed to compare clinical outcomes (e.g. patient survival) between groups. Of the 3305 patients who experienced peritonitis during the study period, 553 episodes (16.7%) resulted in transfer to HD and 101 patients subsequently returned to PD. HD transfer was significantly and independently predicted by inpatient treatment of peritonitis [odds ratio (OR) 11.45, 95% confidence interval (CI) 7.14-18.36] and the recovered microbiologic profile of organisms recognized to be associated with moderate (20-40%) to high (>40%) rates of catheter removal (moderate: OR 2.45, 95% CI 1.89-3.17; high: OR 8.63, 95% CI 6.44-11.57). Matched case-control analyses yielded comparable results among Interim, Permanent and Never HD groups in terms of patient survival (P = 0.28), death-censored technique survival [hazard ratio (HR) 0.87, 95% CI 0.59-1.28; P = 0.48] and peritonitis-free survival (HR 0.84, 95% CI 0.50-1.39, P = 0.49). In an observational registry study of first peritonitis episodes, temporary HD transfer was not associated with inferior patient-level clinical outcomes when compared with others who either never required HD transfer or remained on HD permanently if all patient-level and peritonitis-related factors were considered equal. Therefore, return to PD after a temporary HD due to peritonitis

    The quality of induction of temporary staff and that of the care provided to patients are closely related. The use of temporary nurses is very much on the agenda in the face of just-in-time staffing. How can these constraints be reconciled? A study carried out on the reception of temporary nurses showed the need to engage in steps towards improvement of this aspect.

    Temporary henna tattoos have become increasingly widespread among children and young people, especially in holiday spots in recent years. Although reactions to henna tattoo are becoming progressively more common, only few cases of a henna pseudo-tattoo resulting in temporary hypertrichosis have been reported so far. Here, we have reported a 5-year-old girl who developed allergic contact dermatitis and localized hypertrichosis on her right arm after application of temporary henna tattoo during summer holiday.

    A 6-year-old boy developed a skin eruption 10 days after application of a temporary tattoo advertised as a “natural black henna tattoo.” The eruption was a delayed hypersensitivity reaction to the tattoo ink. The textile dye paraphenylenediamine (PPD) is a common industrial allergen and can be found in some temporary tattoo inks. This case describes the reaction and reviews the international literature pertaining to PPD and temporary tattoos. PMID:17256041

    Several insect species seem to persist not only in permanent but also in temporary ponds where they face particularly harsh conditions and frequent extinctions. Under such conditions, gene flow may prevent local adaptation to temporary ponds and may promote phenotypic plasticity, or maintain apparent population persistence. The few empirical studies on insects suggest the latter mechanism, but no studies so far quantified gene flow including both pond types. We investigated the effects of pond type and temporal variation on population genetic differentiation and gene flow in the damselfly Lestes viridis in northern Belgium. We report a survey of two allozyme loci (Gpi, Pgm) with polyacrylamide gel electrophoresis in 14 populations from permanent and temporary ponds, and compared these results with similar data from the same permanent populations one year before. The data suggested that neither pond-drying regime, nor temporal variation have a substantial effect on population genetic structuring and did not provide evidence for stable population differentiation in L. viridis in northern Belgium. Gene flow estimates were high within permanent and temporary ponds, and between pond types. Our data are consistent with a source-sink metapopulation system where temporary ponds act as sinks in dry years, and are quickly recolonized after local population extinction. This may create a pattern of apparent population persistence of this species in permanent and temporary ponds without clear local adaptation.

    The evaluation of the hydrological alteration of a stream due to human activities is a first step to assess its overall quality and to design management strategies for its potential restoration. This task is currently made comparing impacted against unimpacted hydrographs, with the help of software tools, such as the IHA (Indicators of Hydrologic Alteration). Then, the environmental evaluation of the hydrological alteration is to be made in terms of its expectable menace for the original biological communities and/or its help for the spread of invasive species. However, when the regime of the target stream is not perennial, there are four main difficulties for implementing methods for assessing hydrological alteration: i) the main hydrological features relevant for biological communities in a temporary stream are not quantitative (discharges) but qualitative (temporal patterns of states such as flowing water, stagnant pools or lack of surface water), ii) stream flow records do not inform on the temporal occurrence of stagnant pools, which act as refugees for many species during the cessation of flow, iii) as most of the temporary streams are ungauged, the evaluation of their regime must be determined by using alternative methods such as remote sensing or citizen science, and iv) the biological quality assessment of the ecological status of a temporary stream must be conducted following a sampling schedule adapted to the flow regime and using adequate reference conditions. In order to overcome these challenges using an operational approach, the TREHS freely available software tool has been developed within the EU LIFE TRIVERS project (LIFE13 ENV/ES/000341). This software allows for the input of information coming from flow simulations obtained using any rainfall-runoff model (to set an unimpacted reference stream regime) and compares them with the information obtained from flow gauging records, interviews made to local citizens, instantaneous observations made by

  19. Temporary anchorage devices – Mini-implants

    PubMed Central

    Singh, Kamlesh; Kumar, Deepak; Jaiswal, Raj Kumar; Bansal, Amol

    2010-01-01

    Orthodontists are accustomed to using teeth and auxiliary appliances, both intraoral and extraoral, to control anchorage. These methods are limited in that it is often difficult to achieve results commensurate with our idealistic goals. Recently, a number of case reports have appeared in the orthodontic literature documenting the possibility of overcoming anchorage limitations via the use of temporary anchorage devices—biocompatible devices fixed to bone for the purpose of moving teeth, with the devices being subsequently removed after treatment. Although skeletal anchorage is here to stay in orthodontics, there are still many unanswered questions. This article describes the development of skeletal anchorage and provides an overview of the use of implants for orthodontic anchorage. PMID:22442547

  20. Temporary fire sealing of penetrations on TFTR

    SciTech Connect

    Hondorp, H.L.

    1981-02-01

    The radiation shielding provided for TFTR for D-D and D-T operation will be penetrated by numerous electrical and mechanical services. Eventually, these penetrations will have to be sealed to provide the required fire resistance, tritium sealability, pressure integrity and radiation attenuation. For the initial hydrogen operation, however, fire sealing of the penetrations in the walls and floor is the primary concern. This report provides a discussion of the required and desirable properties of a temporary seal which can be used to seal these penetrations for the hydrogen operation and then subsequently be removed and replaced as required for the D-D and D-T operations. Several candidate designs are discussed and evaluated and recommendations are made for specific applications.

  1. Nutrient mitigation in a temporary river basin.

    PubMed

    Tzoraki, Ourania; Nikolaidis, Nikolaos P; Cooper, David; Kassotaki, Elissavet

    2014-04-01

    We estimate the nutrient budget in a temporary Mediterranean river basin. We use field monitoring and modelling tools to estimate nutrient sources and transfer in both high and low flow conditions. Inverse modelling by the help of PHREEQC model validated the hypothesis of a losing stream during the dry period. Soil and Water Assessment Tool model captured the water quality of the basin. The 'total daily maximum load' approach is used to estimate the nutrient flux status by flow class, indicating that almost 60% of the river network fails to meet nitrogen criteria and 50% phosphate criteria. We recommend that existing well-documented remediation measures such as reforestation of the riparian area or composting of food process biosolids should be implemented to achieve load reduction in close conjunction with social needs.

  2. Temporary migration and regional development in China.

    PubMed

    Ma, Z

    1999-05-01

    "A new approach to migration in developing countries is used in this paper, which integrates into the migration process the experiences of moving to cities, working in urban areas, and returning to the countryside. As a result, rural labor migration is directly linked to rural development through remittances, as well as through physical and human capital brought back by return migrants. Migration information is mainly drawn from China's 1995 1% National Population Survey.... It has been found that patterns of temporary migration are mainly shaped by the magnetic force of the growth-pole region. Job opportunities created there in labor-intensive industries have attracted large numbers of migrants, first from the surrounding rural areas and then from the peripheral regions, enhancing migration propensity in both areas."

  3. Temporary Immersion System for Date Palm Micropropagation.

    PubMed

    Othmani, Ahmed; Bayoudh, Chokri; Sellemi, Amel; Drira, Noureddine

    2017-01-01

    The temporary immersion system (TIS) is being used with tremendous success for automation of micropropagation of many plant species. TIS usually consists of a culture vessel comprising two compartments, an upper one with the plant material and a lower one with the liquid culture medium and an automated air pump. The latter enables contact between all parts of the explants and the liquid medium by setting overpressure to the lower part of the container. These systems are providing the most satisfactory conditions for date palm regeneration via shoot organogenesis and allow a significant increase of multiplication rate (5.5-fold in comparison with that regenerated on agar-solidified medium) and plant material quality, thereby reducing production cost.

  9. Schedules of Controlled Substances: Temporary Placement of 4-Fluoroisobutyryl Fentanyl into Schedule I. Temporary scheduling order.

    PubMed

    2017-05-03

    The Administrator of the Drug Enforcement Administration is issuing this temporary scheduling order to schedule the synthetic opioid, N-(4-fluorophenyl)-N-(1-phenethylpiperidin-4-yl)isobutyramide (4-fluoroisobutyryl fentanyl or para-fluoroisobutyryl fentanyl), and its isomers, esters, ethers, salts and salts of isomers, esters, and ethers, into schedule I pursuant to the temporary scheduling provisions of the Controlled Substances Act. This action is based on a finding by the Administrator that the placement of 4-fluoroisobutyryl fentanyl into schedule I of the Controlled Substances Act is necessary to avoid an imminent hazard to the public safety. As a result of this order, the regulatory controls and administrative, civil, and criminal sanctions applicable to schedule I controlled substances will be imposed on persons who handle (manufacture, distribute, reverse distribute, import, export, engage in research, conduct instructional activities or chemical analysis, or possess), or propose to handle, 4-fluoroisobutyryl fentanyl.

  10. A biological tool to assess flow connectivity in reference temporary streams from the Mediterranean Basin.

    Many streams in the Mediterranean Basin have temporary flow regimes. While timing for seasonal drought is predictable, they undergo strong inter-annual variability in flow intensity. This high hydrological variability and associated ecological responses challenge the ecological status assessment of temporary streams, particularly when setting reference conditions. This study examined the effects of flow connectivity in aquatic macroinvertebrates from seven reference temporary streams across the Mediterranean Basin where hydrological variability and flow conditions are well studied. We tested for the effect of flow cessation on two streamflow indices and on community composition, and, by performing random forest and classification tree analyses we identified important biological predictors for classifying the aquatic state either as flowing or disconnected pools. Flow cessation was critical for one of the streamflow indices studied and for community composition. Macroinvertebrate families found to be important for classifying the aquatic state were Hydrophilidae, Simuliidae, Hydropsychidae, Planorbiidae, Heptageniidae and Gerridae. For biological traits, trait categories associated to feeding habits, food, locomotion and substrate relation were the most important and provided more accurate predictions compared to taxonomy. A combination of selected metrics and associated thresholds based on the most important biological predictors (i.e. Bio-AS Tool) were proposed in order to assess the aquatic state in reference temporary streams, especially in the absence of hydrological data. Although further development is needed, the tool can be of particular interest for monitoring, restoration, and conservation purposes, representing an important step towards an adequate management of temporary rivers not only in the Mediterranean Basin but also in other regions vulnerable to the effects of climate change.

  11. Effect of temporary filling materials on repair bond strengths of composite resins.

    PubMed

    2008-08-01

    Endodontic access cavities sometimes can be prepared through a permanent composite restoration. Between the appointments, temporary cements are used to seal access cavities and may have negative effect on bonding of further composite restoration. The purpose of this study was to compare shear bond strength of composite to composite which had been in contact with various temporary filling materials. Standard cavities were prepared on 160 acrylic resin blocks, obturated with composite resin (Clearfil AP-X, Kuraray, Japan) and randomly divided into eight groups (n = 20). Group 1 received no treatment. From group 2-8, composite surfaces were covered with the following cements temporarily: Zinc-oxide/calcium-sulphate (Cavit-G, ESPE, Germany), two different Zinc-Oxide-Eugenol materials (ZnOE, Cavex, Holland and IRM, Dentsply, USA), Zinc-phosphate cement (Adhesor, Spofa-Dental, Germany), Zinc-polycarboxylate cement (Adhesor-Carbofine, Spofa-Dental, Germany), Glass-Ionomer-Cement (Argion-Molar, Voco, Germany), or light curing temporary material (Clip, Voco, Germany). The cements were removed mechanically after 1 week storage in distilled water at 37 degrees C and composite surfaces were treated with a self-etch adhesive system (SE-Bond, Kuraray, Japan). Composite resin build-ups were created on composite surfaces. Shear bond strength values were measured using universal testing machine at crosshead speed of 1 mm/min. The data was calculated in MPa and statistically analyzed using one-way ANOVA and Tukey tests. Eugenol-containing cements significantly reduced shear bond strengths of composite to composite (p < 0.05), while the other temporary materials had no adverse effect on shear bond strength (p > 0.05). These findings suggested that temporary filling materials except eugenol-containing materials have no negative effect on composite repair bond strengths.

    The objective of this study was to evaluate the influence of eugenol-containing temporary fillings on the polymerisation of composite materials. Cavities of 2 mm in diameter and 2 mm in depth were prepared in enamel as well as in dentine. Immediately after preparation the cavities of the control group were filled with a light curing composite, a chemical curing composite, or a light and chemical curing composite. The cavities of the experimental group were filled with Nobetec (temporary filling material containing zinc-oxide-eugenol). After six weeks, the Nobetec fillings were removed by means of an excavator, the cavities were cleaned with water and filled with one of the above six composites. The specimens were embedded in Epofix and afterwards cut through the center of the filling. The cut surfaces were polished to 3 microns and afterwards (> 4 days) the hardness was measured with a Knoop hardness testing machine at different distances from the cavity wall. The results of the control group and of the experimental group were compared statistically. The polymerisation of five of the six materials was not inhibited by a temporary filling material containing zinc-oxide-eugenol. The difference in hardness for Brilliant Lux (light curing) was fer-highly significant (p < 0.001) between 0 micron and 100 microns from the cavity margin, if the cavity was first filled with a temporary filling material, containing zinc-oxide-eugenol. The results show that there exist certain composite filling materials that are inhibited in their polymerisation by the tested eugenol containing temporary filling material.

  13. Return to Work After Temporary Disability Pension in Finland.

    When it is possible that the employee's work ability can be restored through treatment or rehabilitation, disability pension in Finland is granted for a fixed period. We examined which factors are associated with return to work (RTW) after such temporary disability pension. The study included all Finnish residents whose temporary disability pension from the earnings-related pension system started in 2008 (N = 10,269). Competing risks regression analysis was applied to examine register-based determinants for RTW after temporary disability pension due to mental disorders, musculoskeletal diseases, other diseases, and injury over a 4-year follow-up period. The overall cumulative incidence of RTW was 25%. RTW was more probable after temporary disability pension due to injury and musculoskeletal diseases and less probable after temporary disability pension due to mental disorders. Younger age and higher education increased RTW but differences between genders, private and public sector employees, and occupational classes were relatively small. The probability of RTW was higher among those who were employed before their temporary disability pension (subhazard ratio in multivariate analysis 2.41 (95% CI 2.13-2.72) and among the 9% who participated in vocational rehabilitation during their pension [SHR 2.10 (95% CI 1.90-2.31)]. With some exceptions, the results were fairly similar for all diagnostic causes of temporary disability pension. Return to work after temporary disability pension was relatively uncommon. Nevertheless, in all diagnostic groups RTW continued for the whole follow-up period. The low educated and those not employed before temporary disability pension need more support in their RTW. The strong association between vocational rehabilitation and RTW suggests that increasing rehabilitation among those with impaired work ability may promote RTW.

    Solar cookers are described that were tested for future use in developing countries. They consisted of a flat plate collector and one cooking unit with or without temporary heat storage. The goal was to develop inexpensive and efficient systems using materials available in developing countries. The tests showed that cooking with solar is comparable to cooking with electricity or gas and can be adapted to daily cooking processes, including broiling and baking.

    This paper is concerned with the asymptotic properties of a stochastic delayed SIR epidemic model with temporary immunity. Sufficient conditions for extinction and persistence in the mean of the epidemic are established. The threshold between persistence in the mean and extinction of the epidemic is obtained. Compared with the corresponding deterministic model, the threshold affected by the white noise is smaller than the basic reproduction number R0 of the deterministic system.

    Linsenmaier, Ulrich; Rieger, Johannes; Schenk, Franz; Rock, Clemens; Mangel, Eugen; Pfeifer, Klaus Juergen

    1998-11-15

    Purpose: We describe the results of a preliminary prospective study using different recently developed temporary and retrievable inferior vena cava (IVC) filters. Methods: Fifty temporary IVC filters (Guenther, Guenther Tulip, Antheor) were inserted in 47 patients when the required period of protection against pulmonary embolism (PE) was estimated to be less than 2 weeks. The indications were documented deep vein thrombosis (DVT) and temporary contraindications for anticoagulation, a high risk for PE, and PE despite DVT prophylaxis. Results: Filters were removed 1-12 days after placement and nine (18%) had captured thrombi. Complications were one PE during and after removal of a filter, two minor filter migrations, and one IVC thrombosis. Conclusion: Temporary filters are effective in trapping clots and protecting against PE, and the complication rate does not exceed that of permanent filters. They are an alternative when protection from PE is required temporarily, and should be considered in patients with a normal life expectancy.

  10. Temporary and permanent wetland macroinvertebrate communities: Phylogenetic structure through time

    NASA Astrophysics Data System (ADS)

    Silver, Carly A.; Vamosi, Steven M.; Bayley, Suzanne E.

    2012-02-01

    Water permanence has been previously identified as an important factor affecting macroinvertebrate diversity and abundance in wetlands. Here, we repeatedly sampled the macroinvertebrate communities in 16 permanent and 14 temporary wetlands in Alberta, Canada. Temporary wetlands were predicted to have more closely related taxa and reduced species richness due to the specialized adaptations required to survive in a temporary habitat. We analyzed the species richness (SR) and phylogenetic structure of communities, focusing on three measures of relatedness: Phylogenetic Distance (PD), Net Related Index (NRI) and Nearest Taxon Index (NTI). We also examined the influence of taxonomic scale on resulting phylogenetic structure. Overall, taxa were more diverse and abundant in permanent wetlands. As expected, PD and SR were greatest in permanent wetlands. NTI and NRI metrics suggest permanent wetland communities are primarily structured by biotic interactions, such as competition and predation. Conversely, temporary wetland communities appear to be affected more by environmental filtering, with fewer groups being able to survive and reproduce in the relatively limited time that these environments contain water. Insect and dipteran assemblages differed from the patterns found when examining all taxa together for communities for both permanent and temporary wetlands, tending to become more phylogenetically clustered as the season progressed. Conversely, lophotrochozoan and gastropod assemblages closely matched the patterns observed for full communities in permanent wetlands, suggesting a role for biotic interactions. Given the contrasting patterns observed for permanent and temporary wetlands, macroinvertebrate diversity at the landscape level may be best conserved by maintaining both habitat types.

  11. Temporary umbilical loop colostomy for anorectal malformations.

    2012-11-01

    Transumbilical surgical procedures have been reported to be a feasible, safe, and cosmetically excellent procedure for various pediatric surgical diseases. Umbilical loop colostomies have previously been created in patients with Hirschsprung's disease, but not in patients with anorectal malformations (ARMs). We assessed the feasibility and cosmetic results of temporal umbilical loop colostomy (TULC) in patients with ARMs. A circumferential skin incision was made at the base of the umbilical cord under general anesthesia. The skin, subcutaneous tissue, and fascia were cored out vertically, and the umbilical vessels and urachal remnant were individually ligated apart from the opening in the fascia. A loop colostomy was created in double-barreled fashion with a high chimney more than 2 cm above the level of the skin. The final size of the opening in the skin and fascia was modified according to the size of the bowel. The bowel wall was fixed separately to the peritoneum and fascia with interrupted 5-0 absorbable sutures. The bowel was opened longitudinally and everted without suturing to the skin. The loop was divided 7 days postoperatively, and diversion of the oral bowel was completed. The colostomy was closed 2-3 months after posterior saggital anorectoplasty through a peristomal skin incision followed by end-to-end anastomosis. Final wound closure was performed in a semi-opened fashion to create a deep umbilicus. TULCs were successfully created in seven infants with rectourethral bulbar fistula or rectovestibular fistula. Postoperative complications included mucosal prolapse in one case. No wound infection or spontaneous umbilical ring narrowing was observed. Skin problems were minimal, and stoma care could easily be performed by attaching stoma bag. Healing of umbilical wounds after TULC closure was excellent. The umbilicus may be an alternative stoma site for temporary loop colostomy in infants with intermediate-type anorectal malformations, who undergo radical

    Studies performed at an open-pit mine in the Karaganda Region showed that excavator operators were exposed to the complex action of vibration, noise, unfavourable microclimate and dust in the parameters exceeding the existing norms. A comparative analysis of the levels of morbidity with temporary disability and the actual occupational conditions proved the latters' influence on the morbidity rate, particularly in case with diseases caused by respiratory infections, spinal disorders (radiculitis, lumbago), blood circulation dysfunctions, all of which should be attributed to occupationally conditioned ailments. Hygienic and preventive measures, with due account of specific groups of diseases, can considerably improve the workers' health status and decrease morbidity with temporary disability rates.

    1991-12-01

    In a series of experimental studies the hypothesis that periods of silence reduce the risk of hearing impairment was tested. The noise exposure was comparable to that of workers in the engineering industry: e.g., during 10 minutes' grinding. Two different experiments with rest periods of different lengths and repetition rates were performed. Frequent short periods of silence offered the best protection. Significantly less influence on hearing, temporary threshold shift (TTS), was obtained when repeated 5-second pauses were allowed than during continuous work. The studies also included experiments with impulse noise. This consisted of a different series of sledgehammer impacts, with a peak level of 130 dB(A). Different repetition rates were tested in order to determine whether the reaction time of the acoustic reflex influenced its protective effect. A low repetition rate gave less temporary impairment than a higher repetition rate, although the total number of impacts was the same.

    To evaluate the efficacy of adhesive tape for temporary management of inturned upper eyelid eyelashes. In a prospective, consecutive, comparative, nonrandomized, interventional case series, 50 patients (100 eyes) had inturned eyelashes with at least 1 of 3 symptoms: foreign body sensation, itchiness, and tearing. Transpore tape was applied to the right upper eyelid of each patient; the left eye was used as a control. A questionnaire was used to assess relief or persistence of the symptoms before, during, and after tape adhesion. Analysis of variance showed a significant difference between the study and control groups (P = .002). Tukey honestly significant difference analysis revealed a significant difference in symptoms before and during tape adhesion and a significant difference during and after tape adhesion. Symptoms in the control eye remained unchanged. Use of adhesive tape can be an effective temporary measure for relief of symptoms of inturned upper eyelid eyelashes.

    Objective The purpose of this study was to evaluate, by shear bond strength (SBS) testing, the influence of different types of temporary cements on the final cementation using conventional and self-etching resin-based luting cements. Material and Methods Forty human teeth divided in two halves were assigned to 8 groups (n=10): I and V (no temporary cementation); II and VI: Ca(OH)2-based cement; III and VII: zinc oxide (ZO)based cement; IV and VIII: ZO-eugenol (ZOE)-based cement. Final cementation was done with RelyX ARC cement (groups I to IV) and RelyX Unicem cement (groups V to VIII). Data were analyzed statistically by ANOVA and Tukey's test at 5% significance level. Results Means were (MPa): I - 3.80 (±1.481); II - 5.24 (±2.297); III - 6.98 (±1.885); IV - 6.54 (±1.459); V - 5.22 (±2.465); VI - 4.48 (±1.705); VII - 6.29 (±2.280); VIII - 2.47 (±2.076). Comparison of the groups that had the same temporary cementation (Groups II and VI; III and VII; IV and VIII) showed statistically significant difference (p<0.001) only between Groups IV and VIII, in which ZOE-based cements were used. The use of either Ca(OH)2 based (Groups II and VI) or ZO-based (Groups III and VII) cements showed no statistically significant difference (p>0.05) for the different luting cements (RelyXTM ARC and RelyXTM Unicem). The groups that had no temporary cementation (Groups I and V) did not differ significantly from each other either (p>0.05). Conclusion When temporary cementation was done with ZO- or ZOE-based cements and final cementation was done with RelyX ARC, there was an increase in the SBS compared to the control. In the groups cemented with RelyX Unicem, however, the use of a ZOE-based temporary cement affected negatively the SBS of the luting agent used for final cementation. PMID:20379679

    Occlusal endodontic access preparations are occasionally made in teeth without removing the original restoration. However, microleakage between restorative materials that are placed at different times has not been extensively studied. Therefore, our objective was to compare microleakage at three areas: between an access opening restorative material and the cavity wall; between an additional material placed later to patch a secondary opening in the first restorative material and the original restorative material itself; and between the secondarily placed material and the cavity wall. Standard endodontic access preparations were made in 120 noncarious, nonrestored crowns of extracted human molars. These teeth were divided into six experimental groups. Another four molars were controls. The endodontic access cavities were restored with either IRM or amalgam as the primary restorative material. After 14 days, half of the primary restorations was removed, and this defect was filled with a secondary restorative material: IRM, Caviton, or a double seal of Caviton and IRM. Microleakage was measured linearly as the extent of basic fuchsin dye penetration under a stereomicroscope after thermal cycling (5 degrees and 55 degrees C for 100 cycles) and tooth sectioning. Wilcoxon signed-rank test was used for statistical analysis. Results indicated significantly less microleakage between primary and secondary restorative materials placed at different times than microleakage between primary temporary restorative materials and the access cavity wall, regardless of the type of primary restorative material used (IRM or amalgam).

    Celebrations and bursts of communal joy can occur spontaneously in human communities based on mechanisms of emotional contagion. Some examples of similar collective excitement have been reported in animals when they reunite or anticipate rewards, but little is known about the processes and meaning of these multiple interactions. We experimentally studied such collective arousals in two captive groups of Tonkean macaques (Macaca tonkeana) within the context of reunions following the temporary separation of two subgroups. We compared the behaviors of individuals after separation periods of 2 and 48 h with a control period with no separation. This study showed that it is possible to reproducibly induce bursts of friendly interactions in which groupmates run around over a period of several minutes, embracing and grasping one another while displaying numerous affiliative vocalizations and facial expressions. The longer the period of separation, the higher and longer-lasting the rates of affiliative interactions were. Individuals affiliated more frequently with groupmates from a previously separated subgroup than with those having stayed in their own subgroup. Collective arousal was followed by a quieter period characterized by high rates of contact-sitting and social grooming. These results point at the role of collective arousals in social cohesion; they could resolve social tension and renew social relationships. We propose that the emotional state experienced by Tonkean macaques during such events represents a disposition similar to that giving rise to what we humans call "shared joy."

  3. Temporary Losses of Highway Capacity and Impacts on Performance

    SciTech Connect

    Chin, S.M.

    2002-07-31

    Traffic congestion and its impacts significantly affect the nation's economic performance and the public's quality of life. In most urban areas, travel demand routinely exceeds highway capacity during peak periods. In addition, events such as crashes, vehicle breakdowns, work zones, adverse weather, and suboptimal signal timing cause temporary capacity losses, often worsening the conditions on already congested highway networks. The impacts of these temporary capacity losses include delay, reduced mobility, and reduced reliability of the highway system. They can also cause drivers to re-route or reschedule trips. Prior to this study, no nationwide estimates of temporary losses of highway capacity had been made by type of capacity-reducing event. Such information is vital to formulating sound public policies for the highway infrastructure and its operation. This study is an initial attempt to provide nationwide estimates of the capacity losses and delay caused by temporary capacity-reducing events. The objective of this study was to develop and implement methods for producing national-level estimates of the loss of capacity on the nation's highway facilities due to temporary phenomena as well as estimates of the impacts of such losses. The estimates produced by this study roughly indicate the magnitude of problems that are likely be addressed by the Congress during the next re-authorization of the Surface Transportation Programs. The scope of the study includes all urban and rural freeways and principal arterials in the nation's highway system for 1999. Specifically, this study attempts to quantify the extent of temporary capacity losses due to crashes, breakdowns, work zones, weather, and sub-optimal signal timing. These events can cause impacts such as capacity reduction, delays, trip rescheduling, rerouting, reduced mobility, and reduced reliability. This study focuses on the reduction of capacity and resulting delays caused by the temporary events mentioned

    This study compares the convenience of temporary housing complexes in the Iwate Prefecture following the 2011 Tohoku Earthquake. The study was targeted at three major cities in the southern coastal area of Iwate Prefecture, namely, Kamaishi, Ofunato, and Rikuzen- Takata, that were most heavily struck by the earthquake-triggered tsunami. We conducted a network analysis in geographical information system software using the coordinate data of several daily infrastructures. Temporary housing complexes within the defined service area of each infrastructure were assigned a score of 1.00. The main findings are summarized below: 1) The temporary housing complexes in Rikuzen-Takata City were less accessible to infrastructures (as evidenced by the low coverage area of 1.00 scores) than the other investigated cities. 2) The scores of Kamaishi City and Ofunato City were statistically similar, but complexes in Ofunato City were surrounded by slightly more infrastructures (greater coverage area of 1.00 scores) than Kamaishi City. 3) We identified more than the predicted number of blank areas in the targeted areas. Thus, we consider that support services for people living in such areas are urgently required, especially in the realms of daily shopping, banking, and healthcare.

  6. Effect of repeated vertical loads on microleakage of IRM and calcium sulfate-based temporary fillings.

    2001-12-01

    Temporary fillings are commonly used to seal endodontic access cavities between visits. IRM and Cavidentin were selected to represent two widely used groups of temporary filling materials. The first is a reinforced zinc oxide-eugenol preparation that is mixed at chairside, whereas the second is a ready-to-use calcium sulfate-based material that gained popularity due to its convenience of application. The seal provided by the aforementioned materials was studied using a radioactive tracer quantitative assay. When compared as passive temporary filling, the two provided a similar quality of seal. However, when subjected to repetitive "occlusal" cyclic loading of 4 kg, IRM was clearly superior to the calcium sulfate-based material. Whereas IRM maintained a reasonable seal, the calcium sulfate-based fillings deteriorated and lost the ability to seal. These results suggest that even though calcium sulfate-based materials may be useful when not subjected to any occlusal forces, IRM should be preferred whenever occlusal loads may be applied. Furthermore it is demonstrated that testing such materials for microleakage with no reference to mastication forces may be of limited value.

  7. Effect of temporary open-air markets on the sound environment and acoustic perception based on the crowd density characteristics.

    The sound environment and acoustic perception of open-air markets, which are very common in high-density urban open spaces, play important roles in terms of the urban soundscape. Based on objective and subjective measurements of a typical temporary open-air market in Harbin city, China, the effects of the temporary open-air market on the sound environment and acoustic perception were studied, considering different crowd densities. It was observed that a temporary open-air market without zoning increases the sound pressure level and subjective loudness by 2.4dBA and 0.21dBA, respectively, compared to the absence of a temporary market. Different from the sound pressure level and subjective loudness, the relationship between crowd density and the perceived acoustic comfort is parabolic. Regarding the effect of a temporary open-air market with different zones on the sound environment and acoustic perception, when the crowd densities were the same, subjective loudness in the fruit and vegetable sales area was always higher than in the food sales area and the clothing sales area. In terms of acoustic comfort, with an increase in crowd density, acoustic comfort in the fruit and vegetable sales area decreased, and acoustic comfort in the food sales area and the clothing sales area exhibited a parabolic change trend of increase followed by decrease. Overall, acoustic comfort can be effectively improved by better planning temporary open-air markets in high-density urban open spaces. Copyright © 2017 Elsevier B.V. All rights reserved.

  8. Validating alternative methodologies to estimate the regime of temporary rivers when flow data are unavailable.

    Hydrological data for assessing the regime of temporary rivers are often non-existent or scarce. The scarcity of flow data makes impossible to characterize the hydrological regime of temporary streams and, in consequence, to select the correct periods and methods to determine their ecological status. This is why the TREHS software is being developed, in the framework of the LIFE Trivers project. It will help managers to implement adequately the European Water Framework Directive in this kind of water body. TREHS, using the methodology described in Gallart et al. (2012), defines six transient 'aquatic states', based on hydrological conditions representing different mesohabitats, for a given reach at a particular moment. Because of its qualitative nature, this approach allows using alternative methodologies to assess the regime of temporary rivers when there are no observed flow data. These methods, based on interviews and high-resolution aerial photographs, were tested for estimating the aquatic regime of temporary rivers. All the gauging stations (13) belonging to the Catalan Internal Catchments (NE Spain) with recurrent zero-flow periods were selected to validate this methodology. On the one hand, non-structured interviews were conducted with inhabitants of villages near the gauging stations. On the other hand, the historical series of available orthophotographs were examined. Flow records measured at the gauging stations were used to validate the alternative methods. Flow permanence in the reaches was estimated reasonably by the interviews and adequately by aerial photographs, when compared with the values estimated using daily flows. The degree of seasonality was assessed only roughly by the interviews. The recurrence of disconnected pools was not detected by flow records but was estimated with some divergences by the two methods. The combination of the two alternative methods allows substituting or complementing flow records, to be updated in the future through

    Background The temporary tracheostoma’s metastases of head and neck cancer had already been reported in the literature. So far, they had been considered as regional dissemination of the malignant disease. We report a case of temporary tracheostoma’s metastasis of carcinoma from non-head-and-neck primary site, what has not been reported in the literature, yet. Therefore, it is the first reported case of the systemic dissemination of malignant tumour into temporary tracheostoma. Case report. Fifty-four-year-old female patient, previously treated for a rectal adenocarcinoma, reported in our office with exophytic pink tissue masses around the temporary tracheostoma. The biopsy and immunohistochemistry findings were consistent with temporary tracheostoma’s metastasis of the rectal adenocarcinoma. The patient received palliative radiotherapy and died of systemic progression of the disease. Conclusions The patients with history of primary cancer of any origin and exophytic proliferating changes around the tracheostoma require an appropriate diagnostic work-up including a biopsy. The type of treatment depends on the extent of the disease, previous therapy and general condition of the patient. PMID:25435853

  11. Temporary Cementitious Sealers in Enhanced Geothermal Systems

    2011-12-31

    Unlike conventional hydrothennal geothermal technology that utilizes hot water as the energy conversion resources tapped from natural hydrothermal reservoir located at {approx}10 km below the ground surface, Enhanced Geothermal System (EGS) must create a hydrothermal reservoir in a hot rock stratum at temperatures {ge}200 C, present in {approx}5 km deep underground by employing hydraulic fracturing. This is the process of initiating and propagating a fracture as well as opening pre-existing fractures in a rock layer. In this operation, a considerable attention is paid to the pre-existing fractures and pressure-generated ones made in the underground foundation during drilling and logging. These fractures in terms of lost circulation zones often cause the wastage of a substantial amount of the circulated water-based drilling fluid or mud. Thus, such lost circulation zones must be plugged by sealing materials, so that the drilling operation can resume and continue. Next, one important consideration is the fact that the sealers must be disintegrated by highly pressured water to reopen the plugged fractures and to promote the propagation of reopened fractures. In response to this need, the objective of this phase I project in FYs 2009-2011 was to develop temporary cementitious fracture sealing materials possessing self-degradable properties generating when {ge} 200 C-heated scalers came in contact with water. At BNL, we formulated two types of non-Portland cementitious systems using inexpensive industrial by-products with pozzolanic properties, such as granulated blast-furnace slag from the steel industries, and fly ashes from coal-combustion power plants. These byproducts were activated by sodium silicate to initiate their pozzolanic reactions, and to create a cemetitious structure. One developed system was sodium silicate alkali-activated slag/Class C fly ash (AASC); the other was sodium silicate alkali-activated slag/Class F fly ash (AASF) as the binder of temper

    Temporary medical workers provide a vital role for the medical profession. These individuals, however, occupy a unique work arrangement as professional-specific temporary workers. Temporary medical workers often find themselves bearing the burdens of both medical workers and temporary workers. In partnership with the largest medical temporary agency in the United States, we content analyzed the responses of 86 medical temporary workers, geared at uncovering the primary stressors and coping strategies this sample enacted. Our findings concluded that temporary medical workers experienced stressors associated with both their medical and temporary roles, although more stressors were associated with temporary work than with medical care. Participants also relied heavily on coping strategies that allowed them to avoid these stressors.

    Soil observations networks at the national scale play an integral role in hydrologic modeling, drought assessment, agricultural decision support, and our ability to understand climate change. Understanding soil moisture variability is necessary to apply these measurements to model calibration, business and consumer applications, or even human health issues. The installation of soil moisture sensors as sparse, national networks is necessitated by limited financial resources. However, this results in the incomplete sampling of the local heterogeneity of soil type, vegetation cover, topography, and the fine spatial distribution of precipitation events. To this end, temporary networks can be installed in the areas surrounding a permanent installation within a sparse network. The temporary networks deployed in this study provide a more representative average at the 3 km and 9 km scales, localized about the permanent gauge. The value of such temporary networks is demonstrated at test sites in Millbrook, New York and Crossville, Tennessee. The capacity of a single U.S. Climate Reference Network (USCRN) sensor set to approximate the average of a temporary network at the 3 km and 9 km scales using a simple linear scaling function is tested. The capacity of a temporary network to provide reliable estimates with diminishing numbers of sensors, the temporal stability of those networks, and ultimately, the relationship of the variability of those networks to soil moisture conditions at the permanent sensor are investigated. In this manner, this work demonstrates the single-season installation of a temporary network as a mechanism to characterize the soil moisture variability at a permanent gauge within a sparse network.

    The use of blocked-out duplicate casts in the fabrication of temporary removable partial dentures has been described. Temporary removable partial dentures produced in this controlled manner fit properly and aid in minimizing intraoral damage. Accuracy of fit is assured because all relief is accomplished by block out on the surveyor during the laboratory phase rather than by random grinding of the prosthesis at insertion. In addition, the original cast is salvaged and can be used as a meaningful reference during the finishing process in the laboratory (Fig. 5).

    We present details of four field campaigns carried out on different volcanoes of Kamchatka in 2012-2015. Each campaign was performed in three main steps: (i) installation of the temporary network of seismic stations; (ii) autonomous continuous registration of three component seismic signal; (III) taking off the network and downloading the registered data. During the first campaign started in September 2012, 11 temporary stations were installed over the Avacha group of volcanoes located 30 km north to Petropavlovsk-Kamchatsky in addition to the seven permanent stations operated by the Kamchatkan Branch of the Geophysical Survey (KBGS). Unfortunately, with this temporary network we faced with two obstacles. The first problem was the small amount of local earthquakes, which were detected during operation time. The second problem was an unexpected stop of several stations only 40 days after deployment. Nevertheless, after taking off the network in August 2013, the collected data appeared to be suitable for analysis using ambient noise. The second campaign was conducted in period from August 2013 to August 2014. In framework of the campaign, 21 temporary stations were installed over Gorely volcano, located 70 km south to Petropavlovsk-Kamchatsky. Just in time of the network deployment, Gorely Volcano became very seismically active - every day occurred more than 100 events. Therefore, we obtain very good dataset with information about thousands of local events, which could be used for any type of seismological analysis. The third campaign started in August 2014. Within this campaign, we have installed 19 temporary seismic stations over Tolbachik volcano, located on the south side of the Klyuchevskoy volcano group. In the same time on Tolbachik volcano were installed four temporary stations and several permanent stations operated by the KBGS. All stations were taking off in July 2015. As result, we have collected a large dataset, which is now under preliminary analysis

  17. Demand for temporary agency nurses and nursing shortages.

    2013-08-01

    There is an ongoing debate about the reasons for the growth of temporary employment of registered nurses (RNs). Some argue that efficiency incentives to increase flexibility and reduce labor costs are the principal cause, while others point to shortages of RNs as the stronger determinant. Using hospital-level data from California's Office of Statewide Health Planning and Development, we find a significant trend of increasing demand for agency nurses during the years of RN shortage. Demand rose with inpatient days, patient demand fluctuation, and the level of fringe benefits. Competition between hospitals and unionization, however, did not affect hospitals' demand for temporary RNs. © The Author(s) 2014.

    A temporary pacing electrode can function as a diagnostic as well as a therapeutic tool. This is illustrated in two patients whose permanent pacemakers unexpectedly failed. In the first patient a demand pacemaker was inhibited by a magnet rather than converting to the asynchronous mode. In the second the pacemaker appeared to be producing low-voltage potentials not detectable on the surface electrocardiogram. The presence of a temporary pacing electrode can be useful for defining the cause of pacemaker failure and the nature of any associated arrhythmias. Images FIG. 1 FIG. 3 PMID:7260759

    The paper involves exposure to noise of the State Police officers connected with the use of firearms. The noise generated by these weapons is of short duration and high intensity. The research was carried out during the sessions of firearm training of State Police officers to assess exposure to noise. The values of the various investigations, both audiometric and phonometric, carried out made it possible to demonstrate a significant exposure and a temporary increase in the threshold, above the frequency of 6000 Hz. Even taking account of the abatement from use of headphones, an exposure was demonstrated that was above the statutory limits, as was confirmed by the temporary hearing threshold shift.

    Temporary work disability (TWD) is more common in patients with fibromyalgia (FM) than among the rest of the workers. To describe the differences between patients who take sick leave (TWD group) and those who continue to work regularly (control group). To determine what factors are associated with TWD. Multicentre, cross-sectional study with a cohort of patients with FM seen in rheumatology clinics throughout Spain. The following information was recorded: demographic data, clinical manifestations, comorbidities, health self-perception, emotional issues, functional capacity, physical function tests, utilization of healthcare resources, TWD during the past 12 months, and quitting paid employment due to the disease. Descriptive statistics was used to compare variables between the TWD group and the control group. A logistic regression analysis was done to determine which factors are associated with TWD. The study cohort was composed of 301 patients with FM (women: 96.7%) with a mean age of 48.7 ± 8.5 years and a disease duration of 11.5 ± 9.1 years. There were 56.8% active workers, of whom 67.8% had had some TWD. The mean TWD length was 44 ± 69.6 days/year. TWD correlated significantly with sedentary work, clinical manifestations, comorbidities, self-perceived health, poor functional capacity, physical function, and healthcare resource utilization. The factors independently associated with TWD are sedentary work, more clinical manifestations, fatigue, and poor flexibility. Of the cases of people who quit their jobs, 66.9% were associated with FM. TWD in patients with FM is associated with sedentary work, a worse clinical situation, and worse functional capacity.

  2. Duration of temporary catheter use for hemodialysis: an observational, prospective evaluation of renal units in Brazil

    PubMed Central

    2011-01-01

    Background For chronic hemodialysis, the ideal permanent vascular access is the arteriovenous fistula (AVF). Temporary catheters should be reserved for acute dialysis needs. The AVF is associated with lower infection rates, better clinical results, and a higher quality of life and survival when compared to temporary catheters. In Brazil, the proportion of patients with temporary catheters for more than 3 months from the beginning of therapy is used as an evaluation of the quality of renal units. The aim of this study is to evaluate factors associated with the time between the beginning of hemodialysis with temporary catheters and the placement of the first arteriovenous fistula in Brazil. Methods This is an observational, prospective non-concurrent study using national administrative registries of all patients financed by the public health system who began renal replacement therapy (RRT) between 2000 and 2004 in Brazil. Incident patients were eligible who had hemodialysis for the first time. Patients were excluded who: had hemodialysis reportedly started after the date of death (inconsistent database); were younger than 18 years old; had HIV; had no record of the first dialysis unit; and were dialyzed in units with less than twenty patients. To evaluate individual and renal unit factors associated with the event of interest, the frailty model was used (N = 55,589). Results Among the 23,824 patients (42.9%) who underwent fistula placement in the period of the study, 18.2% maintained the temporary catheter for more than three months until the fistula creation. The analysis identified five statistically significant factors associated with longer time until first fistula: higher age (Hazard-risk - HR 0.99, 95% CI 0.99-1.00); having hypertension and cardiovascular diseases (HR 0.94, 95% CI 0.9-0.98) as the cause of chronic renal disease; residing in capitals cities (HR 0.92, 95% CI 0.9-0.95) and certain regions in Brazil - South (HR 0.83, 95% CI 0.8-0.87), Midwest (HR 0
