Abstract
BACKGROUND Open hand fractures are one of the most common injuries in the pediatric population. These injuries are at higher risk of infection, especially in cases of frank contamination. Several studies on adult hand fractures are available in the literature; however, pediatric open hand fractures have yet to be extensively studied. This study aimed to define pediatric open hand fracture's demographics, clinical characteristics, and treatment patterns. METHODS Using the Protected Health Information database, pediatric patients (<18 y old) with the diagnosis of open hand fracture from June 2016 to June 2018 were extracted. Demographic, treatment, and follow-up data were collected. Clinical outcomes included readmission and postoperative infection rates. RESULTS There were a total of 4516 patients who met the inclusion criteria; the median age was 7 years (interquartile range: 3 to 11); 60% males; 60% white. Displaced fractures occurred in 74% of patients, with the right hand (52%) and middle finger (27%) predominance. The most common mechanism of injury was a crushing injury in-between objects (56%). Associated nerve injury occurred in 78 patients (4%) and vascular injury in 43 patients (2%). Open reduction and internal fixation were performed in 30% of patients. Cephalosporins were the most commonly prescribed antibiotics (73%), followed by aminopenicillins (7%). Nine patients had complications related to surgical intervention (0.2%), and postoperative infection occurred in 44 patients (1%). CONCLUSIONS Pediatric open hand fractures most often occur during childhood and more frequently in males. These fractures tend to be more distal and displaced; reduction and fixation are required in one-third of the cases. Despite the absence of treatment guidelines and variability, this injury exhibits low complication rates. LEVEL OF EVIDENCE Level III, retrospective study.

Abstract
Ulnar collateral ligament reconstruction (UCLR) is frequently performed among injured overhead-throwing athletes. One of the most common graft choices when performing a UCLR is the ipsilateral palmaris longus tendon (PL). The purpose of this study was to investigate the material properties of aseptically processed cadaveric knee collateral ligaments (kMCL) as a potential graft source for UCLR and compare them to the gold standard PL autograft. Each PL and kMCL cadaveric sample was subjected to cyclic preconditioning, stress relaxation, and load-to-failure testing, and the mechanical properties were recorded. PL samples exhibited a greater average decrease in stress compared to the kMCL samples during the stress-relaxation test (p < 0.0001). PL samples also demonstrated a greater average Young's modulus in the linear region of the stress-strain curve compared to the kMCL samples (p < 0.01). The average yield strain and maximum strain of kMCL samples were significantly greater than the PL, p = 0.03 and 0.02, respectively. Both graft materials had comparable maximum toughness and demonstrated a similar ability to deform plastically without rupture. The clinical significance of our result is that prepared knee medial collateral ligament allografts may provide a viable graft material for use in the reconstruction of elbow ligaments.

Abstract
BACKGROUND In Xeroderma Pigmentosum (XP), the main means of preventing skin and eye cancers is extreme protection against ultraviolet radiation (UVR). Protection is most important for the face. OBJECTIVES We aimed to assess how well patients with XP adhere to medical advice to protect against UVR by objectively estimating the mean daily dose of UVR to the face. METHODS We objectively estimated the UVR dose to the face in 36 XP patients and 25 healthy individuals over 3 weeks in the summer. We used a new methodology which combined UVR dose measurements from a wrist-worn dosimeter with an activity diary record of face photoprotection behaviour for each 15 minute period spent outside. A protection factor was associated with each behaviour, and the data analysed using a negative binomial mixed-effects model. RESULTS The mean daily UVR dose (weighted for DNA damage capacity) to the face in the XP patients was 0.13 Standard Erythemal Doses (SED) (mean in healthy individuals = 0.51 SED). There was wide variation between patients (range <0.01 - 0.48 SED/day). Self-caring adult patients had a very similar UV dose to the face to cared-for patients (0.13 vs 0.12 SED/day) despite photoprotecting much more poorly when outside, because the self-caring adults were outside in daylight much less. CONCLUSIONS Photoprotection behaviour varies widely within the XP group indicating that non-adherence to photoprotection advice is a significant issue. Timing and duration of going outside are as important as photoprotective measures taken when outside, to determine the UVR exposure to the face. This new methodology will be of value in identifying the sources of UVR exposure in other conditions where facial UV exposure is a key outcome, particularly in patients with multiple non-melanoma skin cancers.

Abstract
PURPOSE OF THE REVIEW Chronic low back pain (CLBP) is a major contributor to societal disease burden and years lived with disability. Nonspecific low back pain (LBP) is attributed to physical and psychosocial factors, including lifestyle factors, obesity, and depression. Mechanical low back pain occurs related to repeated trauma to or overuse of the spine, intervertebral disks, and surrounding tissues. This causes disc herniation, vertebral compression fractures, lumbar spondylosis, spondylolisthesis, and lumbosacral muscle strain. RECENT FINDINGS A systematic review of relevant literature was conducted. CENTRAL, MEDLINE, EMBASE, PubMed, and two clinical trials registry databases up to 24 June 2015 were included in this review. Search terms included: low back pain, over the counter, non-steroidal anti-inflammatory (NSAID), CLBP, ibuprofen, naproxen, acetaminophen, disk herniation, lumbar spondylosis, vertebral compression fractures, spondylolisthesis, and lumbosacral muscle strain. Over-the-counter analgesics are the most frequently used first-line medication for LBP, and current guidelines indicate that over-the-counter medications should be the first prescribed treatment for non-specific LBP. Current literature suggests that NSAIDs and acetaminophen as well as antidepressants, muscle relaxants, and opioids are effective treatments for CLBP. Recent randomized controlled trials also evaluate the benefit of buprenorphine, tramadol, and strong opioids such as oxycodone. This systematic review discusses current evidence pertaining to non-prescription treatment options for chronic low back pain.

Abstract
PURPOSE OF REVIEW This review presents epidurolysis as a procedure to alleviate pain and disability from epidural adhesions. It reviews novel and groundbreaking evidence, describing the background, indications, benefits and adverse events from this procedure in an effort to provide healthcare experts with the data required to decide on an intervention for their patients. RECENT FINDINGS Epidural adhesions (EA) or epidural fibrosis (EF) is defined as non-physiologic scar formation secondary to a local inflammatory reaction provoked by tissue trauma in the epidural space. Often, it is a sequelae of surgical spine intervention or instrumentation. The cost associated with chronic post-operative back pain has been reported to be up to nearly $12,500 dollars per year; this, coupled with the increasing prevalence of chronic lower back pain and the subsequent increase in surgical management of back pain, renders EF a significant cost and morbidity in the U.S. Though risk factors leading to the development of EA are not well established, epidural fibrosis has been reported to be the culprit in up to 46% of cases of Failed Back Surgery Syndrome (FBSS), a chronic pain condition found in up to 20-54% of patients who receive back surgery. Moreover, EF has also been associated with lumbar radiculopathy after lumbar disc surgery. Epidurolysis is defined as the mechanical dissolution of epidural fibrotic scar tissue for persistent axial spine or radicular pain due to epidural fibrosis that is refractory to conservative therapy Endoscopic lysis of adhesions is a procedural technique which has been shown to improve chronic back pain in one-third to one-half of patients with clinically symptomatic fibrous adhesions. Here we review some of the novel evidence that supports this procedure in EA and FBSS. SUMMARY The literature concerning epidurolysis in the management of epidural adhesions is insufficient. Prospective studies, including randomized controlled trials and observational studies, have suggested epidurolysis to be effective in terms of pain reduction, functional improvement, and patient satisfaction scores. Observational studies report epidurolysis as a well-tolerated, safe procedure. Current evidence suggests that epidurolysis may be used as an effective treatment modality for epidural adhesions. Nonetheless, further high quality randomized controlled studies assessing the safety and efficacy of epidurolysis in the management of epidural adhesions is needed.

Abstract
PURPOSE OF REVIEW Chronic foot pain constitutes a large portion of the chronic pain burden in the overall population. Plantar fasciitis is one of the most common and most easily identifiable causes of chronic foot pain. The syndrome has been estimated to cause 11 to 15% of foot pain visits, requiring professional care. Moreover, studies have suggested that 1 in 10 people will develop plantar fasciitis at some point in their life. Conservative management has been shown to be effective and considered first-line treatment. Minimally invasive treatment options are typically reserved for those who fail conservative management. With the advent of new techniques and improvements in current therapeutic options, there has been an expansion of available minimally invasive treatment options. The purpose of this review is to provide a comprehensive update on the current understanding of minimally invasive treatments of plantar fasciitis. RECENT FINDINGS This review shows that conservative management continues to be the first-line therapy, whereas other treatment options were those who failed conservative management using modern techniques that have shown improving effectiveness, with successful restoration of patient functionality, recovery, and satisfaction. However, a multitude of these minimally invasive treatment options are evolving. CONCLUSION While conservative management continues to be the mainstay of treatment for plantar fasciitis, multiple minimally invasive treatment options are emerging with potential effectiveness in reducing pain and improving the function.

Abstract
PURPOSE OF REVIEW Chronic ankle pain is a prevalent and significant cause of chronic pain. While the definition of chronic ankle pain is heterogeneous and poorly defined in the literature, systematic reviews and meta-analyses have estimated this condition to be a prevalent and debilitating source of chronic pain. The most identifiable and prominent cause of chronic ankle pain is chronic ankle instability (CAI), a condition defined by instability of the ankle-joint complex. It is a common consequence of lateral ankle sprains or ligamentous injuries and can be described as a failure of the lateral ankle joint complex after an acute, or recurring, ankle injury. The objective of this manuscript is to provide a comprehensive review of CAI diagnosis and our current understanding of minimally invasive treatment options. RECENT FINDINGS First-line treatment is conservative management, some of which includes neuromuscular rehabilitation, balance training, nonsteroidal anti-inflammatory drugs (NSAIDs), manual mobilization, ice therapy, and compression. While conservative management is effective, additional treatments for those who fail conservative management, or who seek alternative options also have been explored. Recent advances and modern techniques have expanded available treatment options, many of which are becoming less invasive, and have shown improving functionality, recovery, and patient satisfaction. Minimally invasive treatments highlighted in this review include: arthroscopic surgery, steroid injections, plasma-rich plasma injections, hyaluronic acid (HA) injections, medicinal signaling cell injections, radiofrequency therapies, and shockwave therapies. This review will discuss some of these current treatments for minimally invasive treatment of CAI, as well as suggest novel treatments for clinical trials and further investigation.

Abstract
It is important to evaluate stakeholder feedback regarding any change to a clinical supervision model to maintain quality. The Quality Practical Experience (QPE) instruments offer both the nurse on the ward involved with supervising student learning and the student nurse the opportunity to evaluate their satisfaction with the supervision model. This paper reports on the evaluation of the construct validity and the reliability of the QPE instruments measuring nurse and nursing student satisfaction with the clinical supervision model. Methodological design for the reliability and validation of a measuring instrument. The nurse and the student QPE instruments were tested with convenience samples of 488 nurses and 1116 student nurses, respectively. Psychometric tests included internal reliability, test-retest reliability and factor analyses. Exploratory factor analysis for both QPEs supported a three-factor solution; the nurse QPE explained 48% and student nurse QPE 45% of variance. Internal reliability and test-retest reliability were stable over time (nurse QPE ICC = 0.82; student nurse QPE ICC = 0.71). Both QPE instruments were found to be valid and reliable. Feedback from all stakeholders involved with supporting student nurses during clinical placement is important.

Abstract
Abstract The recurrence rate following acute anterior shoulder dislocations is high, particularly in young, active individuals. The purpose of this paper is to provide a narrative overview of the best available evidence and results with regards to diagnostic considerations, comorbidities, position of immobilization, surgical versus conservative management, and time to return to play for the management of primary anterior shoulder dislocations. Three independent reviewers performed literature searches using PubMed, MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials. Randomized controlled trials and systematic reviews meeting inclusion criteria from 1930 to April 2019 were appraised and discussed with the intent to consolidate the best available evidence with regards to lowering recurrence rates. A majority of studies support early surgical intervention for individuals between 21 and 30 years of age following primary shoulder dislocations, as this group is particularly susceptible to recurrence. Conservative treatment plans favor 1–3 weeks of immobilization in internal rotation, followed by rehabilitation. Surgical methods are associated with longer time to return to play, but lower recurrence rates. Return to play time is best determined on an individualized basis, when subjective and objective function of both shoulders is determined to be symmetric. This paper broadly summarizes the best available evidence for the management of primary anterior shoulder dislocations. There remains a need for randomized studies to determine ideal long-term treatment following conservative or surgical management, as general timelines for returning to play following injury remain vague.

Abstract
BACKGROUND AND PURPOSE Uncertainty persists regarding the safety and efficacy of endovascular therapy of M2 occlusions following IV tPA. We reviewed the impact of revascularization on clinical outcomes in 83 patients with M2 occlusions in the Interventional Management of Stroke III trial according to specific M1-M2 segment anatomic features. MATERIALS AND METHODS Perfusion of any M2 branch distinguished M2-versus-M1 occlusion. Prespecified modified TICI and arterial occlusive lesion revascularization and clinical mRS 0-2 end points at 90 days for endovascular therapy-treated M2 occlusions were analyzed. Post hoc analyses of the relationship of outcomes to multiple baseline angiographic M2 and M1 subgroup characteristics were performed. RESULTS Of 83 participants with M2 occlusion who underwent endovascular therapy, 41.0% achieved mRS 0-2 at 90 days, including 46.6% with modified TICI 2-3 reperfusion compared with 26.1% with modified TICI 0-1 reperfusion (risk difference, 20.6%; 95% CI, -1.4%-42.5%). mRS 0-2 outcome was associated with reperfusion for M2 trunk (n = 9) or M2 division (n = 42) occlusions, but not for M2 branch occlusions (n = 28). Of participants with trunk and division occlusions, 63.2% with modified TICI 2a and 42.9% with modified TICI 2b reperfusion achieved mRS 0-2 outcomes; mRS 0-2 outcomes for M2 trunk occlusions (33%) did not differ from distal (38.2%) and proximal (26.9%) M1 occlusions. CONCLUSIONS mRS 0-2 at 90 days was dependent on reperfusion for M2 trunk but not for M2 branch occlusions. For M2 division occlusions, good outcome with modified TICI 2b reperfusion did not differ from that in modified TICI 2a. M2 segment definition and occlusion location may contribute to differences in revascularization and good outcome between Interventional Management of Stroke III and other endovascular therapy studies.

Abstract
Epithelial to mesenchymal transition (EMT) promotes tumor progression and invasion. As no study has focused on gastroesophageal junction (GEJ) tumors, the expression of three EMT-related proteins (S100A4, vimentin, and Snail1) was investigated with the aim of assessing their pathologic and prognostic significance. Resection specimens were obtained from 104 patients who underwent surgery for GEJ adenocarcinoma, without preoperative chemotherapy. Three tissue cores were obtained from each of the tumor body (TB), luminal surface (LS), and invasive edge (IE) to produce tissue microarrays, and immunohistochemical staining was performed. The microarrays were scored independently by two observers. The demographic and histopathologic details of the patients were collected. Overall positive expression was observed in 88 (S100A4, 85%), 16 (vimentin, 14%), and 92 (Snail1, 89%) tumors. Staining for S100 A4 was positive in 79 (76%) of TB, 69 (66%) of IE, and 69 (66%) of LS specimens. Staining for vimentin was positive in 7 (6%) of TB, 11 (11%) of IE, and 5 (5%) of LS specimens. Staining for Snail1 was positive in 83 (80%) of TB, 51 (49%) of IE, and 78 (75%) of LS specimens. Positive staining of TB for S100A4 (P = 0.04) and Snail1 at IE (P = 0.01) was associated with involvement of circumferential resection margins. Positive staining for S100A4 in the TB (P = 0.02) and LS (P = 0.01) was associated with poor 5-year overall survival. Vimentin had no statistically significant relationships with pathologic factors or outcome. The acquisition of mesenchymal protein S100A4 is associated with a poor prognosis in patients with GEJ tumors who undergo potentially curative surgery, and LS samples can be used to obtain prognostic information. Increased EMT-related protein expression (S100A4, Snail1) is associated with the involvement of circumferential resection margin.

Abstract
Accurate human leucocyte antigen (HLA) typing results are essential in determining the degree of compatibility between donor and recipient in both solid organ (SO) and hematopoietic stem cell (HSC) transplantation. Current HLA typing methodologies can generate ambiguous results which may need resolving. This group-specific sequencing approach allowed investigation into the presence of the low expressor HLA-A*24:02:01:02L allele and the rare HLA-A*02:64 allele in a SO transplant recipient and a HSC transplant recipient, respectively. Locus-specific amplification of HLA-A was performed. Exons 2 and 3 were sequenced in both directions followed by group-specific sequencing to resolve ambiguities. Hemizygous sequence data of intron 2 generated from the HLA-A*24 allele indicated the presence of the HLA-A*24:02:01:01 allele. HLA-A*02:64 was identified by sequencing the allele in isolation over exons 2 and 3 and allowed confirmation of this allele sequence with the IMGT/HLA database (Accession number AY297166). This approach is cost efficient and can be modified to sequence alleles at other HLA loci. It has also been adapted to characterize the novel HLA-DQB1*06:48 allele (Accession number HE647646) as well as the non-HLA gene, UGT2B17, making it a useful tool to augment existing typing methodologies.

Abstract
Provincial and regional decision makers in the injury prevention field were interviewed in British Columbia (B.C.) to obtain their views about best processes for the transfer or dissemination of relevant data. These decision makers (n = 13) indicated that data should provide them with a holistic and comprehensive picture to support their decision processes. In addition, they felt information about injury types and rates should be linked backward to determinants or causes and forward to consequences or outcomes. This complete chain of data is needed for planning and evaluating health promotion interventions. It was also felt that data providers needed to devote more effort to fostering effective receptor capacity, so that injury prevention professionals will be better able to understand, interpret and apply the data. These findings can likely be generalized to other jurisdictions and policy areas, and offer additional insight into the practicalities of knowledge transfer and exchange in researcher/decision maker partnerships.

Abstract
We have reviewed the data from our regional Bone Tumour Registry on patients with osteosarcoma diagnosed between 1933 and 2004 in order to investigate the relationship between survival and changes in treatment. There were 184 patients with non-metastatic appendicular osteosarcoma diagnosed at the age of 18 or under. Survival was calculated using Kaplan-Meier curves, and multivariate analysis was performed using the Cox regression proportional hazards model. The five-year survival improved from 21% between 1933 and 1959, to 62% between 1990 and 1999. During this time, a multi-disciplinary organisation was gradually developed to manage treatment. The most significant variable affecting outcome was the date of diagnosis, with trends in improved survival mirroring the introduction of increasingly effective chemotherapy. Our experience suggests that the guidelines of the National Institute for Clinical Excellence on the minimum throughput of centres for treatment should be enforced flexibly in those that can demonstrate that their historical and contemporary results are comparable to those published nationally and internationally.

Abstract
534 Background: NEAT and the SCTBG BR9601 trial address the role of Epirubicin (E) as an adjunct to CMF in adjuvant chemotherapy for women with early breast cancer (EBC). Methods: NEAT compared E (100mg/m2 x4cycles) followed by classical (c)CMF (x4cycles) with cCMF (x6cycles); BR9601 compared E (100mg/m2 × 4cycles) followed by iv dose modified CMF q3w (750:50:600 ×4cycles) with iv CMF (x8cycles). Eligibility was completely excised EBC, requiring adjuvant chemotherapy, and start of treatment <10 wks from surgery. Primary outcome measures were relapse-free-survival (RFS) and overall survival (OS). A joint efficacy analysis of NEAT (n=2,021) and BR9601 (n=370) triggered by planned 5-year median follow-up (FU) and estimated 800 RFS events and 600 deaths has 85% power to detect 5% two-sided differences. Results: In 2,391 eligible patients, characteristics were balanced across treatments: 72% node +ve; 59% <50 years old; 47% pre-menopausal; 58% tumours grade 3; 55% >2cms; 32% ER-ve, 50% ER+ve (18% NA). At a median FU of 6.2 yrs, 710 relapses or deaths without relapse and 570 deaths are observed. Despite lower than anticipated event rates in the control arm, these updated results confirm a highly significant benefit in favour of ECMF for both RFS (HR 0.75 (95%CI 0.64–0.87) p=0.0002) and OS (HR 0.74 (0.62–0.87) p=0.0004), independent of trial and prognostic factors. In 1458 NEAT patients (in whom data are available), 68% were to receive tamoxifen; chemotherapy scheduling data is available for 843, of whom 46% were declared concurrent and 54% sequential. In a non-pre-planned retrospective analysis, sequential tamoxifen shows a trend for advantage on RFS (HR 0.78 (0.59–1.02) p=0.06). We have amenorrhoea data on 598 NEAT and BR9601 pre-menopausal women, of whom 72% became amenorrhoeic by the end of chemotherapy. In this instance, developing amenorrhoea showed no advantage for RFS (HR 0.90 (0.65–1.24) or OS (HR 0.99 (0.68–1.44)). Conclusions: This updated definitive analysis adds to the Overview in respect of an anthracycline advantage and confirms ECMF as an established and effective standard adjuvant therapy for EBC.

Abstract
This article describes a case of necrotizing fasciitis in a 52-year-old man with previously undiagnosed diabetes. Treatment involved massive debridement and subsequent dressing of the open surgical wound. A modern hydrofibre dressing (Aquacel) was inserted intraoperatively and subsequently continued postoperatively. Wound healing occurred over 3 months and the patient was discharged with no disability. The dressing managed the exudate level and kept the wound moist. It also was well tolerated by the patient, was comfortable and easy for the nurses to remove and apply.

Abstract
OBJECTIVES To investigate the efficacy of botulinum toxin A in chronic low back pain and associated disabilities. METHODS Thirty-one consecutive patients with chronic low back pain who met the inclusion criteria were studied: 15 received 200 units of botulinum toxin type A, 40 units/site at five lumbar paravertebral levels on the side of maximum discomfort, and 16 received normal saline. Each patient's baseline level of pain and degree of disability was documented using the visual analogue scale (VAS) and the Oswestry Low Back Pain Questionnaire (OLBPQ). The authors reevaluated the patients at 3 and 8 weeks (visual analogue scale) and at 8 weeks (OLBPQ). RESULTS At 3 weeks, 11 of 15 patients who received botulinum toxin (73.3%) had >50% pain relief vs four of 16 (25%) in the saline group (p = 0.012). At 8 weeks, nine of 15 (60%) in the botulinum toxin group and two of 16 (12.5%) in the saline group had relief (p = 0.009). Repeat OLBPQ at 8 weeks showed improvement in 10 of 15 (66.7%) in the botulinum toxin group vs three of 16 (18.8%) in the saline group (p = 0.011). No patient experienced side effects. CONCLUSION Paravertebral administration of botulinum toxin A in patients with chronic low back pain relieved pain and improved function at 3 and 8 weeks after treatment.

Abstract
Previous experimental research in other topic areas has shown that the choice of response alternatives can influence respondents' reporting of the frequency of vaguely defined events and that the set of response alternatives is treated as information in the interpretation of the question. The aim of this study was to examine whether such affects would occur in the context of respondents reporting of health-related events using high and medium frequency closed format response categories, which might be used interchangeably by researchers. The study consisted of a postal survey of n = 518 patients aged > or = 18 years randomly selected from the patient list of a diabetes centre and who were equally and randomly allocated to one of three conditions (Condition A: high frequency response alternatives/horizontal orientation; condition B: medium frequency response alternatives/horizontal orientations; condition C: high frequency response alternatives/vertical orientation). Testing for the effect of response alternatives for the combined responses of five vaguely defined questions between conditions A and B was chi 2 = 5.5, p = 0.019, for the difference in proportions, indicating that overall, those respondents presented with response alternatives discriminating at medium frequency, reported significantly fewer target events than those presented with high frequency response alternatives. Testing for the effect of orientation of the combined question responses between conditions A and C, differences in proportions between conditions, did not reach statistical significance (p > 0.05). Findings from this and previous studies indicate that response alternatives provide information on the interpretation of vaguely defined questionnaire items and that their choice should not be left to intuition alone when designing questionnaire items.

Abstract
We report the discovery of a class of pyrazole-based compounds that are potent inhibitors of the dihydroorotate dehydrogenase of Helicobacter pylori but that do not inhibit the cognate enzymes from Gram-positive bacteria or humans. In culture these compounds inhibit the growth of H. pylori selectively, showing no effect on other Gram-negative or Gram-positive bacteria or human cell lines. These compounds represent the first examples of H. pylori-specific antibacterial agents. Cellular activity within this structural class appears to be due to dihydroorotate dehydrogenase inhibition. Minor structural changes that abrogate in vitro inhibition of the enzyme likewise eliminate cellular activity. Furthermore, the minimum inhibitory concentrations of these compounds increase upon addition of orotate to the culture medium in a concentration-dependent manner, consistent with dihydroorotate dehydrogenase inhibition as the mechanism of cellular inhibition. The data presented here suggest that targeted inhibition of de novo pyrimidine biosynthesis may be a valuable mechanism for the development of antimicrobial agents selective for H. pylori.

Abstract
This study aimed to compare the performance of a hydrofibre (Aquacel) and an alginate (Sorbsan) dressing on acute surgical wounds left to heal by secondary intention. A total of 100 patients were prospectively randomised pre-operatively to receive either the hydrofibre or the alginate dressing. Dressing performance was measured at operation, at 24 hours and seven days. Parameters measured included ease of: application and removal of the first dressing; re-application on the first postoperative day; and removal and re-application one week postoperatively. The hydrofibre dressing received higher scores for all of these categories. Patients in this group also experienced less pain (mild or none) on removal of the first dressing and at one week. However, these results did not achieve statistical significance, and should be seen as a trend. Nevertheless, the authors recommend the use of hydrofibre dressings on open acute surgical wounds.

Abstract
In this prospective randomized controlled trial of the cost benefits of the choice of dressings in acute surgical wounds left to heal by secondary intention, patients had their wounds dressed with either a traditional dressing (ribbon gauze soaked in proflavine) or a modern hydrofibre dressing. Results showed that the hydrofibre dressing, although more expensive than the ribbon gauze, facilitated an earlier discharge from hospital (P = 0.001). The total cost of the patient episode was less in the hydrofibre group (P = 0.01). In an average UK health authority of 300,000 population, 100 bed days a year could be saved releasing an overall potential saving of 55,000 Pounds. A modern hydrofibre dressing allows more effective use of scarce hospital beds and precious financial resources, while still maintaining high quality patient care. It is important that clinical specialists and purchasers of health care should be aware of this clinical and cost-effective advance in the management of acute surgical wounds.

Abstract
Skin biopsies taken from UK cases of erythema migrans rash were cultured for Borrelia burgdorferi sensu lato. Reverse line blotting was used to type the infecting genospecies in PCR-positive cultures and biopsies. B. garinii or B. afzelii was identified in 56% (5/9) of biopsies/cultures tested. All patients were tested by conventional serology. PCR confirmed infection in two patients where serological testing failed to detect antibody.

Abstract
This article, the last in a series of four, discusses the importance of documenting wound care. Studies have shown that nurses do not document wound care as often, or as accurately, as they should in order to comply with the UKCC's (1998) Guidelines for Records and Record Keeping. Although some wound assessment charts have been published and are in use, there is still concern about the validity or reliability of some of these charts. Studies show that further research is necessary in order to validate the charts that are currently in use. An increase in litigation has placed more emphasis on accurate record keeping which shows, in detail, the wound care that is given to each patient. Patients also want to be more informed about their treatment, and this can be done through the use of clinical pathways or multidisciplinary documents. This article also discusses the factors that have to be considered when putting a wound care chart together and gives some examples of existing charts.

Abstract
The third article in this series on surgical wound care discusses the types of dressings currently available, and selection of the correct dressing for a particular wound type. There is an abundance of information on the types of dressings available. Wound management for the individual patient must be decided using best evidence and taking into account patients' increased involvement in their care, new technology and the push to mobilize early, leading to early discharge from hospital. The nurse needs to have a good knowledge of the types of dressings available, the properties of individual dressings and a sound understanding of wound healing, in order to make an informed decision on wound management. General factors such as safety, comfort, pain management and convenience must be borne in mind when deciding which dressing is the best for individual patients, given that dressings now have to be cost-effective as well as clinically effective.

Abstract
A brief survey of eight motor habits, including body-rocking, was administered to two large samples of college undergraduates. A subsample was retested to establish survey reliability and validity. Those indicating engagement in body-rocking were interviewed about their body-rocking. Two psychopathology instruments were administered. The general prevalence of self-described body-rocking was higher than expected, and there were positive correlations among the eight habits. Body-rocking was usually related to negative affect and usually reported to begin during the school years and later. Many individuals said other family members engaged in body-rocking. Psychopathology assessments indicated higher levels of general distress and higher prevalence of Generalized Anxiety Disorder in this subsample compared with a group not reporting body-rocking.

Abstract
We have generated two conditionally immortalized neuronal cell lines from primary cultures of embryonic day 13 (E13) and postmitotic (postnatal day 0; P0) cortical neurons transformed with the temperature-sensitive SV-40 large-T antigen. Two clonal cell lines (CN1.4 from E13 cultures and SJ3.6 from P0 cultures) were isolated and stable maintained in vitro. Both cell lines expressed a number of neuronal markers such as the neurofilaments, glutamic acid decarboxylase 67, neuron-specific enolase, and the BG21 isoform of the myelin basic protein gene. At 34 degrees C, the CN1.4 cell line had elaborated short processes, whereas the SJ3.6 cell line produced long processes that formed a delicate network. When these cell lines were cultured at 39 degrees C, some of the cellular processes grew longer, adopting a more mature neuronal morphology. Interestingly, at 39 degrees C, the in vitro survival of these cell lines differed significantly. Whereas the survival of CN1.4 cell line was greatly unaffected, SJ3.6 cells died soon after they were cultured at 39 degrees C. The cell death of SJ3.6 cells was accompanied by fragmentation and condensation of DNA in their nuclei, indicative of an apoptotic event. Under these conditions, SJ3.6 showed an upregulation of the p75 receptor. When this cell line was cocultured with oligodendrocytes, astrocytes, or glial conditioned media (GCM), there was a marked increase in survival. In contrast, little effect of glial cells or GCM was observed on the CN1.4 cell line. These lines appear to be useful models to study neuronal-glial interactions in addition to neuronal cell death and the effects of glial factors that promote the survival of neurons.

Abstract
The first article in this series on acute surgical wound care traced the history of surgical wound care from primitive dressings and techniques of closure used in the past to the present-day approaches. It also outlined the classification of acute surgical wounds (Vol 7(18): 1101-6). This second article describes the four stages of wound healing in acute surgical wounds, using clinical slides to illustrate the wound healing process. General factors, such as age, nutrition and medication, and local factors, including a moist environment, blood supply and wound infection, will be discussed to demonstrate their importance in promoting optimum wound healing.
