Abstract
•Key anterior approaches differences in LSTV include vascular (aortic bifurcation/iliocaval confluence), muscular (psoas) and osseus anatomy (inter-crestal tangent/pubic symphysis), when compared to non-LSTV.•There are increased surgical deviations but not significantly greater complications for anterior approaches in LSTV.•Vascular awareness while accessing L45 will be in the presence of a more cephalad ABF and ICC with sacralized L5, and access to the deeper L56 level will be in the presence of a more caudal ABF and ICC in lumbarized S1.

Abstract
BACKGROUND Depressive symptoms are common in patients with Parkinson's disease and depression is a significant predictor of functional impairment, reduced quality of life and general well-being in Parkinson's disease. Despite the high prevalence of depression, evidence on the effectiveness and tolerability of antidepressants in this population is limited. The primary aim of this trial is to establish the clinical and cost effectiveness of escitalopram and nortriptyline for the treatment of depression in Parkinson's disease. METHODS This is a multi-centre, double-blind, randomised placebo-controlled trial in 408 people with Parkinson's disease with subsyndromal depression, major depressive disorder or persistent depressive disorder and a Beck Depression Inventory-II (BDI-II) score of 14 or above. Participants will be randomised into one of three groups, receiving either escitalopram, nortriptyline or placebo for 12 months. Trial participation is face-to-face, hybrid or remote. The primary outcome measure is the BDI-II score following 8 weeks of treatment. Secondary outcomes will be collected at baseline, 8, 26 and 52 weeks and following withdrawal, including severity of anxiety and depression scores as well as Parkinson's disease motor severity, and ratings of non-motor symptoms, cognitive function, health-related quality of life, levodopa-equivalence dose, changes in medication, overall clinical effectiveness, capability, health and social care resource use, carer health-related quality of life, adverse effects and number of dropouts. DISCUSSION This trial aims to determine the effectiveness of escitalopram and nortriptyline for reducing depressive symptoms in Parkinson's disease over 8 weeks, to provide information on the effect of these medications on anxiety and other non-motor symptoms in PD and on impact on patients and caregivers, and to examine their effect on change in motor severity. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT03652870 Date of registration - 29th August 2018.

Abstract
Abstract
Introduction
Reduction of waiting times is key to delivering high quality, efficient health care. Delays experienced by patients requiring radiographs in orthopaedic outpatient clinics are well recognised.
Method
To establish current patient and staff satisfaction, questionnaires were circulated over a two-week period. Waiting time data was retrospectively collected including appointment time, arrival time and the time at which radiographs were taken.
Results
84% (n = 16) of radiographers believed patients would be dissatisfied. However, of the 296 patients questioned, 56% (n = 165) were satisfied. Most patients (89%) felt the waiting time should be under 30 minutes. Only 36% were seen in this time frame. There was moderate negative correlation (R=-0.5); higher waiting times led to increased dissatisfaction. Mean waiting time was 00:37 and the maximum 02:48. Key contributing factors included volume of patients, staff shortages (73.7%), equipment shortages (57.9%) and incorrectly filled request forms. Eight (42.1%) had felt unwell from work related stress.
Conclusions
A concerted effort is needed to improve staff and patient opinion. There is scope for change post COVID. Additional training and exploring ways to avoid overburdening the department would benefit. Numerous patients were open to different days or alternative sites. Funding requirements make updating equipment, expanding the department and recruiting more staff challenging.

Abstract
Long-construct fixations can be complicated by proximal junctional kyphosis. In elderly, high-risk patients with numerous comorbidities, lengthy surgical times and increased blood loss associated with revision osteotomies and extension of fusions are not often tolerated and pose serious life-threatening risks. We present a salvage technique used in a patient with proximal junctional failure and demonstrate its role in improving symptoms and functionality in those not deemed fit for major surgery. Pre- and postoperative pain scores in accordance with the visual analogue scale, walking distances and radiographs were reviewed in a patient who underwent the salvage technique to ascertain the subjective and objective difference in pain and functionality. The patient showed marked improvement in pain scores and walking distances postoperatively. Additionally, the degree of proximal junctional kyphosis was lower on postoperative radiographs. While holding risks of its own, our described technique can be performed in select cases and is a good salvage procedure in high-risk patients. It prevents their exposure to the risks that accompany large revision operations and fusion models with further potential to fail. We recommend that our technique is performed only at specialist centres.

Abstract
In many regions of the world domestic dogs are free roaming and live in close relationship with humans. These free-roaming domestic dogs (FRDD) can cause public health problems such as dog bites and transmission of infectious diseases. To effectively control diseases transmitted by FRDD, knowledge on the dogs' behaviour is required. To identify predictors of home range (HR) size, we collected global positioning system data from 135 FRDD living in eight Aboriginal and Torres Strait Islander communities in Northern Australia. The core HR size ranged from 0·17 to 2·33 ha and the extended HR size from 0·86 to 40·46 ha. Using a linear mixed effect model with a Restricted Maximum Likelihood approach, the dog's sex and reproductive status were identified as predictors of roaming. Non-castrated males had the largest HRs, followed by neutered females. Also, FRDDs were found to roam further during the pre- than the post-wet season. These findings have implications for infectious disease spread. Identification of risk groups for disease spread within a population allows for more targeted disease response and surveillance. Further investigation of predictors of roaming in other FRDD populations worldwide would increase the external validity of such studies.

Abstract
OBJECTIVE To estimate the home range (HR) and investigate the potential predictors for roaming of 58 dogs in four Aboriginal communities in the Northern Territory. DESIGN Prospective study. PROCEDURE Global positioning system (GPS) collars were attached to the dogs for 1-4 days, recording location fixes every 1-3 min. Utilisation distributions (UDs) and extended (95% isopleth) and core (50% isopleth) HRs of dogs were determined. Potential predictors of roaming were assessed. RESULTS Estimated core (median, 0.27 ha) and extended (median, 3.1 ha) HRs differed significantly (P = 0.0225 and 0.0345, respectively) between the four communities; dogs in the coastal community travelled significantly (P < 0.0001) more per day than dogs in the three inland communities studied. Significant associations were found between extended HR size and sex (P = 0.0050) and sex + neuter (P = 0.0218), and between core HR size and sex (P = 0.0010), neuter status (P = 0.0255) and sex + neuter (P = 0.0025). Entire males roamed more than neutered females. The core HR of dogs with poor/fair body condition scores (BCSs) was larger than dogs with ideal/obese BCSs (P = 0.0394). Neutered male dogs also travelled more per day than entire female dogs (P = 0.0475). CONCLUSIONS Roaming information can be used to inform the management of dogs in remote communities and to design disease control programs. Widespread data collection across the Northern Territory should be undertaken to further investigate the associations found in this study, considering that data were collected during relatively short periods of time in one season.

Abstract
Aims Patients with multiple myeloma (MM) develop deposits in the spine which may lead to vertebral compression fractures (VCFs). Our aim was to establish which spinopelvic parameters are associated with the greatest disability in patients with spinal myeloma and VCFs. Patients and Methods We performed a retrospective cross-sectional review of 148 consecutive patients (87 male, 61 female) with spinal myeloma and analysed correlations between spinopelvic parameters and patient-reported outcome scores. The mean age of the patients was 65.5 years (37 to 91) and the mean number of vertebrae involved was 3.7 (1 to 15). Results The thoracolumbar region was most commonly affected (109 patients, 73.6%), and was the site of most posterior vertebral wall defects (47 patients, 31.8%). Poorer Oswestry Disability Index scores correlated with an increased sagittal vertical axis (p = 0.006), an increased number of VCFs (p = 0.035) and sternal involvement (p = 0.012). Poorer EuroQol visual analogue scale scores correlated with posterior vertebral wall defects in the thoracolumbar region (p = 0.012). The sagittal vertical axis increased with the number of fractures and kyphosis in the thoracolumbar (p = 0.009) and lumbar (p < 0.001) regions. Conclusions In MM, patients with VCFs have poorer clinical scores at presentation in the presence of sagittal imbalance. Outcome is particularly affected by multiple fractures in the thoracolumbar and lumbar regions and by failure to prevent kyphosis. Patients with MM should be screened for spinal lesions early.

Abstract
BACKGROUND This review focused on the identification of patient-reported outcome measures (PROMs) used in routine cancer clinical practice, the impact on patient, provider, and system outcomes, and the implementation factors influencing uptake. METHODS A scoping review of the published health literature was conducted using empirical databases, namely, Ovid Medline (2003 to September 2013), CINAHL (2003-2013) and PsycINFO (2003-2013). Scoping reviews are systematic literature reviews in a broad topic area that provide relevant and quantified results about the knowledge available on a particular topic and aim to rapidly map and synthesize the evidence to emphasize what is known. RESULTS From a total of 2447 unique publications, 30 articles that met eligibility criteria were reviewed. PRO use appears to be acceptable to patients, enables earlier detection of symptoms and may improve communication between clinicians and patients. However, the impact of routine PROMs collection on health outcomes is less clear and high-quality research is still warranted. CONCLUSION PROMs use in routine cancer clinical practice is growing with improvements on essential care processes shown but a number of implementation barriers must still be addressed. The lack of standardization in PROMs used in cancer organizations may make it difficult to use these data for quality monitoring in the future.

Abstract
BACKGROUND Sacral chordomas are rare low-to-intermediate grade malignant tumours, which arise from remnants of the embryonic notochord. This review explores prognostic factors in the management of sacral chordomas and provides guidance on the optimal treatment regimens based on the current literature. PATIENTS AND METHODS Electronic searches were performed using MEDLINE, Embase and the Cochrane library to identify studies on prognostic factors in the management of sacral chordomas published between January 1970 and December 2013. The literature search and review process identified 100 articles that were included in the review article. This included both surgical and non-surgical studies on the management of sacral chordomas. RESULTS Sacrectomy with wide resection margins forms the mainstay of treatment but is associated with high risk of disease recurrence and reduced long-term survival. Adequate resection margins may require sacrifice of adjacent nerve roots, musculature and ligaments leading to functional compromise and mechanical instability. Large tumour size (greater than 5-10 cm in diameter), dedifferentiation and greater cephalad tumour extension are associated with increased risk of disease recurrence and reduced survival. Chordomas are poorly responsive to conventional radiotherapy and chemotherapy. CONCLUSION Operative resection with wide resection margins offers the best long-term prognosis. Inadequate resection margins, large tumour size, dedifferentiation, and greater cephalad chordoma extension are associated with poor oncological outcomes. Routine long-term follow-up is essential to enable early detection and treatment of recurrent disease.

Abstract
BACKGROUND Depression associated with Parkinson disease (PD) has a different symptom profile to endogenous depression. The etiology of depression in PD remains uncertain though abnormal serotonergic neurotransmission could play a role. OBJECTIVE To assess with PET serotonergic function via in vivo serotonin transporter (5-HTT) availability in antidepressant-naive patients with PD. METHODS Thirty-four patients with PD and 10 healthy matched control subjects had a clinical battery of tests including the patient-report Beck Depression Inventory-II (BDI-II), the clinician-report Hamilton Rating Scale for Depression (HRSD), and the structured clinical interview for DSM-IV Axis I Disorders (SCID-I). They underwent ¹¹C-DASB PET, a selective in vivo marker of 5-HTT binding in humans. RESULTS BDI-II scores correlated with HRSD scores. Ten of 34 patients with PD (29.4%) had BDI-II and HRSD scores above the discriminative cutoff for PD depression though only half of these patients could be classed on SCID-I criteria as having an anxiety/mood disorder. Patients with PD with the highest scores for depression symptoms showed significantly raised ¹¹C-DASB binding in amygdala, hypothalamus, caudal raphe nuclei, and posterior cingulate cortex compared to low score cases, while ¹¹C-DASB binding values in other regions were similarly decreased in depressed and nondepressed patients with PD compared to healthy controls. CONCLUSION Depressive symptoms in antidepressant-naive patients with PD correlate with relatively higher 5-HTT binding in raphe nuclei and limbic structures possibly reflecting lower extracellular serotonin levels. Our data are compatible with a key role of abnormal serotonergic neurotransmission contributing to the pathophysiology of PD depression and justify the use of agents acting on 5-HTT.

Abstract
OBJECTIVE This randomized, double-blind, multi-centre study compared the long-term safety and tolerability of pimecrolimus cream 1% and topical corticosteroids (TCS) in 658 adults with moderate-severe atopic dermatitis (AD). METHODS Patients applied either pimecrolimus or TCS (i.e. 0.1% triamcinolone acetonide cream and/or 1% hydrocortisone acetate cream) twice daily to all affected areas until complete clearance or for up to 1 year. The study was approved by the institutional review board or ethics committee at each centre. RESULTS A majority of patients treated with either pimecrolimus or TCS used the drug on a continuous basis over 1 year. In patients who had >30% of the body surface involved by AD, the incidence rate of all skin infections was significantly lower in the pimecrolimus group than in the TCS group (95% CI of the treatment difference: -25.3% to -3.4%). The most frequent application site reaction was burning (25.9% of patients on pimecrolimus and 10.9% on TCS), which was transient and mild-moderate in most cases. Three TCS-treated patients reported skin striae. There were no treatment-related serious or clinically significant systemic adverse events. Efficacy was better in patients on continuous TCS therapy, although patients completing the study were similarly well-controlled in both groups. About 42% of the pimecrolimus-treated patients were maintained for 1 year without TCS. CONCLUSION Pimecrolimus demonstrated a favourable safety profile when used to treat adult patients with moderate-severe AD for up to 1 year. A significant proportion of patients could be maintained without TCS for a year.

Abstract
We have assessed the clinical observation that the angle of the contralateral lamina matches the angle required from the sagital plane for the placement of pedicle screws in the subaxial cervical spine. Fifty-four randomly chosen axial CT scans taken between December 2003 and December 2004 were examined. Subjects were excluded if the scan showed signs of fracture, tumour or gross abnormality. The digitised images were analysed on the Philips PACS system using SECTRA software. One hundred and sixty-eight individual vertebrae were assessed between C3 and C7. The following were measured; the angle of the pedicle relative to the sagital plane, the smallest internal and external diameter of the pedicles and the angle of the lamina. Angular measures had a CV% of 3.9%. The re-measurement error for distance was 0.5 mm. Three hundred and thirty-six pedicles were assessed in 25 females and 29 males. Average age was 48.2 years (range 17-85). Our morphologic data from live subjects was comparable to previous cadaveric data. Mean pedicle external diameter was 4.9 mm at C3 and 6.6 mm at C7. Females were marginally smaller than males. Left and right did not significantly differ. In no case was the pedicle narrower than 3.2 mm. Mean pedicle angle was 130 degrees at C3 and 140 degrees at C7. The contralateral laminar angle correlated well at C3, 4, 5 (R (2) = 0.9, C3 P = 0.002, C4 P = 0.06, C5 P = 0.0004) and was within 1 degrees of pedicle angle. At C6, 7 it was within 11 degrees . In all cases a line parallel to the lamina provided a safe corridor of 3 mm for a pedicle implant. The contralateral lamina provides a reliable intraoperative guide to the angle from the sagital plane for subaxial cervical pedicle instrumentation in adults.

Abstract
Hypoxic ischemic encephalopathy may cause early deep white matter abnormalities on MR imaging that usually progress to include gray matter and basal ganglia change. Toxic leukoencephalopathy due to heroin inhalation predominantly causes cerebellar and posterior cerebral radiologic change. Both conditions rarely present clinically and radiologically in a delayed manner with subsequent recovery. We report a case of reversible delayed posthypoxic/toxic leukoencephalopathy with no clinical or radiologic evidence of gray matter insult.

Abstract
INTRODUCTION Ankle fractures are common and many require surgical intervention. It has been well documented that a delay in fracture fixation results in increased length of hospital stay and increased complication rate. Initial delay can also allow swelling or blistering to develop which may necessitate a further delay in operative fixation for up to 1 week. The aim of the current study was to review the length of hospital in-patient stay for operative ankle fractures over the previous 12-month period at our hospital and compare this to the length of hospital stay following the introduction of a fast-track system for the fixation of these fractures (all fractures fixed within 48 h). PATIENTS AND METHODS A retrospective review of all ankle fractures managed by open reduction and internal fixation over a 12-month period was undertaken. A protocol was then agreed to openly reduce and fix these fractures at the earliest possible opportunity over the next 6-month period. We then collected the data on all ankle fractures that needed open reduction and internal fixation over this 6-month period. The pre-protocol and post-protocol groups were then compared for total hospital length of stay and complication rate. RESULTS In the 12-month retrospective review, there were 83 ankle fractures that required surgical intervention. Sixty-two of these had surgery within 48 h (mean length of stay, 5.4 days), and 21 had surgery after 48 h (mean length of stay, 9.5 days). There were 39 ankle fractures in the post-protocol group who all had surgery within 48 h (mean length of stay, 5 days). There was no increase in complication rate after implementation of the fast-track system. CONCLUSIONS This study shows that early operative intervention for ankle fractures reduces the length of hospital stay. Intensive physiotherapy and co-ordinated discharge planning are also essential ingredients for early discharge. Early operative fixation for unstable ankle fractures has substantial cost-saving implications with no increase in complication rate.

Abstract
BACKGROUND A previous cross sectional study found over-representation of a postural instability gait difficulty (PIGD) motor subtype in Parkinson's disease patients with dementia (PDD) and dementia with Lewy bodies (DLB), compared with Parkinson's disease (PD). AIMS (1) To examine rates of cognitive and motor decline over two years in PD (n=40), PDD (n=42) and DLB (n=41) subjects, compared with age matched controls (n=41), (2) to record whether motor phenotypes of PD, PDD, and DLB subjects changed during the study, (3) to find out if cognitive and motor decline in PD was associated with baseline motor subtype, and (4) to report the incidence of dementia in PD patients in relation to baseline motor subtype. RESULTS Most of PDD and DLB participants were PIGD subtype at baseline assessment. In the non-demented PD group, tremor dominant (TD) and PIGD subtypes were more evenly represented. Cognitive decline over two years was greater in PDD and DLB groups (mean decline in MMSE -4.5 and -3.9, respectively), compared with PD (-0.2) and controls (-0.3). There was an association between PIGD subtype and increased rate of cognitive decline within the PD group. Of 40 PD patients, 25% of the 16 PIGD subtype developed dementia over two years, compared with none of the 18 TD or six indeterminate phenotype cases (chi2=6.7, Fisher's exact test p<0.05). CONCLUSION A PIGD motor subtype is associated with a faster rate of cognitive decline in PD and may be considered a risk factor for incident dementia in PD.

Abstract
BACKGROUND Brain perfusion deficits have been reported previously in subjects with Parkinson's disease in comparison with healthy controls. OBJECTIVE To carry out a longitudinal study of perfusion in patients with Parkinson's disease and controls to find areas showing a reduction in perfusion over one year. METHODS Two HMPAO cerebral perfusion scans were acquired one year apart in 30 subjects with Parkinson's disease (mean (SD) age, 76 (5) years) and 34 healthy comparison subjects (76 (7) years). Scans were normalised to the mean intensity in the cerebellum. RESULTS Using SPM99 within groups to investigate regions that showed a decrease in perfusion between scans, it was found that in Parkinson's disease subjects but not controls there was a significant cluster in the frontal lobe (Brodmann area 10) where perfusion decreased over the year. CONCLUSIONS The progressive frontal perfusion deficits in Parkinson's disease are consistent with results from previous structural and neuropsychological studies suggesting frontal lobe involvement and executive dysfunction even in early Parkinson's disease.

Abstract
BACKGROUND One of the core clinical features of dementia with Lewy bodies (DLB) is extrapyramidal syndrome (EPS). Levodopa is currently the gold standard oral therapy for Parkinson's disease (PD), but its use in DLB has been tempered by concerns of exacerbating neuropsychiatric symptoms. AIM To assess the efficacy and tolerability of L-dopa in managing EPS in DLB and to compare the motor response with that seen in PD and PD with dementia (PDD). METHOD EPS assessment consisted of the Unified Parkinson's Disease Rating Scale, motor subsection (UPDRS III), and finger tapping and walking tests. Patients with DLB were commenced on L-dopa. After 6 months, patients were examined in the "off" state, given L-dopa and assessed for motor responses. Identical assessments were performed in patients with PD and PDD also receiving L-dopa. RESULTS Acute L-dopa challenge in 14 DLB patients yielded a mean 13.8% (p = 0.02) improvement in UPDRS III score, compared with 20.5% in PD (n = 28, p < 0.0001) and 23% in PDD (n = 30, p<0.0001) respectively. Finger tapping scores increased (12.3% v 20% and 23%), while walking test scores decreased (32% v 41% and 67%). Of the DLB patients, 36% were classified as "responders" on L-dopa challenge, compared with 70% of the PDD and 57% of the PD patients. Nineteen DLB patients were treated for 6 months with L-dopa (mean daily dose 323 mg). Two withdrew prematurely with gastrointestinal symptoms and two with worsening confusion. CONCLUSION L-dopa was generally well tolerated in DLB but produced a significant motor response in only about one third of patients. Younger DLB cases were more likely to respond to dopaminergic treatment.

Abstract
In 1996 the quality of the early management of 100 consecutive patients referred to the SW Thames regional pelvic and acetabular unit between 1989 and 1992 was studied. The management of these patients was assessed in four specific areas, and guidelines were laid down. It was found that in 56% of patients the early management did not meet these suggested standards, with 34% having deficiencies in more than one area. These results were presented and published. Five years later, the early management of a further 100 consecutive referrals was assessed using these same guidelines, in order to close the audit loop. The treatment of 57% of patients still did not reach the guideline standards, but the number with problems in more than one area fell to 20%. There has been improvement in the early management of pelvic and acetabular injuries. The use of external fixation in cases of severe haemorrhage increased, but frames were often poorly applied. Early communication with the specialist centre was encouraged but unfortunately there was still an unacceptable delay in referral. The frequency of delayed referral actually increased during the 5 years between study groups.

Abstract
Inversion injuries of the ankle are common and most are managed adequately by functional treatment. A significant number will, however, remain symptomatic. Synovial impingement is one cause of continuing pain. This condition is often difficult to diagnose because the physical signs and investigations are non-specific. If the diagnosis is made, treatment by arthroscopic debridement has been shown to be highly effective. Our aim was to describe a new physical sign to help in the diagnosis of anterolateral synovial impingement in the ankle. A cadaver dissection demonstrated the anatomical basis for the physical sign and a prospective clinical study involving 73 patients showed that the lateral synovial impingement test had a sensitivity of 94.8% and a specificity of 88%. We describe the test and conclude that this physical sign will be of use to practitioners treating patients with chronic pain in the ankle after injury.

Abstract
We describe a patient who sustained a displaced isolated intra-articular fracture of the distal ulna, causing limitation of rotation of the forearm. The extent of displacement of the fracture which was not evident on plain radiographs was revealed by CT. The fracture was reduced and internally fixed using a standard technique applicable to the fixation of fractures of the radial head. Full movement was restored. An isolated injury to the distal ulna is rare and requires careful clinical and radiological assessment.

Abstract
OVERVIEW The National Acute Spinal Cord Injury Studies (NASCIS II and III) and the Cochrane review advocate the administration of high dose methylprednisolone following acute traumatic spinal cord injury. OBJECTIVE To determine the actual use and correct implementation of the NASCIS protocols in patients referred to a regional spinal injuries unit. DESIGN Observational study on the timing and correct dosage of methylprednisolone. The admission Frankel grade, American Spinal Injury Association (ASIA) neurological classification were recorded prospectively. SUBJECTS The 100 consecutive patients with complete or incomplete spinal cord injuries (Frankel grade A-D) were studied over a 2 years period. MAIN OUTCOME MEASURE Correct administration of methylprednisolone according to the NASCIS protocols. RESULTS During the study period only 25% of the patients admitted to our spinal injuries unit received methylprednisolone at the referring hospital according to the NASCIS protocols. An additional 10 patients were given methylprednisolone incorrectly. CONCLUSION Evidence based medicine is not being practiced in the management of patients with acute spinal cord injury.

Abstract
OBJECTIVE To assess the short-term acceptability and functionality of the eZ.on condom compared with currently marketed latex (Gossamer) and polyurethane (Avanti) condoms. Method Healthy, sexually active volunteers aged 18-50 years, self-selected from among the UK population, were enrolled in a randomized cross-over trial. Participants were required to test six of each of three condom variants. Data were collected on structured questionnaires by means of postal and telephone contacts. Main outcome measures were breakage and slippage rates, and short-term user acceptability based on participants' ratings documented in end-of-study questionnaires. RESULTS Forty-three couples entered the study, of whom 37 tested the condoms on 512 occasions. There was no statistically significant difference in the clinical breakage rate between eZ.on (3.7%) and the comparator condoms (3.5% for Gossamer and 2.9% for Avanti). Complete slippage rates were similar for eZ.on (2.4%) and Avanti (2.9%). Gossamer had the lowest slippage rate (1.2%), but this difference was not statistically significant. User acceptability was similar for the three condom types; however, there was a trend for more participants to express dissatisfaction with eZ.on, including difficulties with putting on the condom. CONCLUSIONS No firm conclusions can be drawn from this pilot study, but our observations suggest that eZ.on may be an acceptable option for some couples unwilling or unable to use a latex condom.

Abstract
Compression of the left common iliac vein by the right common iliac artery has been well described (Cockett's syndrome). The authors describe a case report of compression of the right common iliac vein by the right internal iliac artery. The patient presented with ipsilateral lower limb oedema. Venography showed smooth extrinsic compression of the right common iliac vein. The CT scan was initially interpreted as showing no extrinsic mass or obvious compressing lesion and lymphography was normal. It was the duplex scan which showed the bifurcation of the right common iliac artery crossing the right common iliac vein and causing significant extrinsic compression.

Abstract
The current study investigates instrument breakages during both emergency and elective orthopaedic surgery. Over a 2 year period a total of 7,775 procedures were performed. We found that 14 instruments were broken during 12 operative cases. Drill bits accounted for the largest proportion of breakages (11/14), and a specialist registrar was the lead surgeon in the majority (8/12) of cases. Only one case had a consultant as the lead surgeon. In seven cases the broken bit of the surgical instrument was left in the patient. Documentation of this peri-operative complication was deficient, and the patient was often not informed.

Abstract
We report the clinical and radiological outcome of 111 primary Taperloc hip arthroplasties implanted with Boneloc bone cement and the effect of stem size on survival. The mean follow-up was 5.3 years (range 3.2-6.6 years). The average age of the patients at operation was 73.4 years. Twenty-seven were male and 84 female. We defined clinical failures as those who had revision for aseptic loosening, or those symptomatic with pain and subsequent confirmation of radiographic loosening. The overall failure rate noted for this type of stem was 20.7%. Failure occurred on average at 3.3 years (0.3-6.3 years). However, when the data is broken down to different sizes of stem, the patients who had smaller Taperloc stems (7.5 mm or 10 mm) had a 27% failure rate whereas stems equal to, or greater than, 12.5 mm had a 12% failure rate over the same period (p < 0.05). As compared to other types of femoral stems used with Boneloc cement, the Taperloc stems survive better. Furthermore, larger stems survive even better. We suggest that these larger stems behave more like uncemented femoral stems. The finish on the stem is not a major contributor as has been suggested in the past.

Abstract
STUDY DESIGN A questionnaire survey. OBJECTIVES To collate and analyze the views of the delegates who attended the European Cervical Spine Research Society (CSRS) meeting on the use of methylprednisolone for acute traumatic spinal cord injury. SUMMARY OF BACKGROUND DATA The NASCIS II and III studies reported improved neurologic recovery in patients who were treated with methylprednisolone within 8 hours of their acute traumatic spinal cord injury. A number of reported commentaries have criticized these trials. A recent audit in the authors' regional spinal injuries unit in the United Kingdom found that a large percentage of patients were not receiving methylprednisolone. The authors decided to collate the views of the delegates at the CSRS regarding the use of steroids for acute traumatic spinal cord injury. METHODOLOGY A questionnaire was created that took into account the positive reported findings as well as the criticisms of the NASCIS studies. Delegates who attended the European CSRS meeting completed this questionnaire. RESULTS Seventy-five percent of the delegates answered that they used or recommended methylprednisolone in the treatment of acute traumatic spinal cord injury. Nevertheless, the delegates had an average of 1.5 reservations about administering methylprednisolone. The most common reservation was that they did not think the improvement conferred to the patients by administering methylprednisolone had been clinically or functionally proven. There were reservations about the validity of the statistical analysis used in the NASCIS studies and by the omission of a placebo group in NASCIS III. The majority of the delegates thought it was not medicolegally negligent to withhold the administration of methylprednisolone in the treatment of acute traumatic spinal cord injury. CONCLUSION The use of methylprednisolone in the treatment of acute traumatic spinal cord injury is still controversial. It would appear from a recent prospective audit at the authors' spinal injuries unit that a large percentage of patients in the United Kingdom are not receiving methylprednisolone. Because so much doubt exists, the NASCIS studies should be repeated.

Abstract
OBJECTIVE To examine whether values of arterial base excess or lactate taken on admission to a general intensive care unit indicate prognosis, and whether this can be used as a screening tool for future intensive care admissions. DESIGN Observational study. SETTING University teaching hospital general adult intensive care unit. PATIENTS 148 consecutive patients admitted to the intensive care unit. INTERVENTIONS Arterial blood samples were obtained on admission to the intensive care unit and 24 h following admission. MEASUREMENTS AND RESULTS Arterial base excess and lactate concentrations were measured from the blood samples. Both base excess and arterial lactate samples on admission have good prognostic abilities (area under the curve on receiver operator characteristic analysis of 0.73, 0.78, respectively). The value of base excess on admission with the best predictive ability was a base excess more negative than -4 mmol/l, and the corresponding value for lactate was greater than 1.5 mmol/l. The combination of these two markers on admission to the intensive care unit led to a sensitivity of 80.3 % and a specificity of 58.7 % for mortality. The achievement of this combination was associated with an increased mortality (50.6 % vs. 15 %, p < 0.0001), older age (70 vs. 61.5 years, p < 0.05), a greater requirement for inotropic support (30.9 % vs. 4.5%, p < 0.0001) and higher organ failure scores both on admission and for the subsequent 24 h. CONCLUSIONS Both base excess and lactate, or the combination of the two, can be used to predict outcome in patients admitted to the intensive care unit. These variables could be utilized to identify patients who have a high risk for mortality and thus who should be admitted to the intensive care unit.

Abstract
Reactivation of latent herpes simplex virus (HSV) in the trigeminal ganglion most commonly gives rise to recurrent herpes labialis and rarely to herpes simplex encephalitis. The mechanisms underlying reactivation of latent trigeminal HSV are complex. Here we report the case history of a 25-year-old woman who developed a fatal, bilateral necrotizing destructive temporal lobe lesion following surgical removal of a cerebellar medulloblastoma and combined radiotherapy and chemotherapy for recurrent tumor. Neuropathologic examination of the brain revealed minimal inflammatory changes, but immunohistochemistry was positive for HSV protein, and HSV deoxyribonucleic acid (DNA) was recovered from formalin-fixed paraffin-embedded brain tissue. The temporal proximity of the surgery, chemotherapy, and radiotherapy to the onset of disease suggests that these factors may have acted as triggers that precipitated conversion of latent HSV to overt HSV.

Abstract
Despite the growing interest in enhancing the cultural awareness for nurse practitioner (NP) students who work with patients from the developing world, there is a dearth of reports on such experiences. This report describes the clinical experiences of NP students from George Mason University (Fairfax, VA) during an intensive 2 weeks in Nicaragua in their final semester, accompanied by an NP faculty member. The program was planned and implemented in collaboration with the Universidad Politecnica de Nicaragua School of Nursing (Managua, Nicaragua). The students' clinical experiences included working in a Health Post and an impoverished community. Students learned to manage clinical problems using minimal resources and acquired an appreciation for the cultural, political, and economic situations from which many of their patients in the United States originate. Recommendations for establishing this type of experience are included.

Abstract
A total of 549 brown trout were caught from two lakes, Lough Feeagh and Bunaveela Lake, in the Burrishoole system, Co. Mayo, Ireland. Seven species of metazoan parasite were detected but only four species occurred in > or = 10% of the sample. The parasite community of the trout was dominated by a single species, Pomphorhynchus laevis, with a prevalence if 58%. Only one allogenic helminth species was recorded from the trout, Diphyllobothrium ditremum, with the community mainly comprising autogenic species. Few differences were found between the two lakes, although the larger lake, Lough Feeagh, did contain some trout which harboured more parasite species and had, on average, fish with higher numbers of individual parasites. Measures of species richness and diversity were very low, indicating an impoverished helminth community with little potential for interspecific interactions. Host age was found to significantly influence these indices of infracommunity structure.

Abstract
Since Ireland is the only country in which Pomphorhynchus laevis (Acanthocephala) uses brown trout (Salmo trutta) as its preferred definitive host, the population biology of the parasite in this host was investigated thus enabling a comparison to be made with data collected on P. laevis from other hosts, particularly the cyprinids, chub and barbel. Over a period of 12 months, 549 brown trout were caught from two lakes, Lough Feeagh and Bunaveela Lake, in the Burrishoole River system, Co. Mayo, Ireland. The parasite component community was dominated by a single species, P. laevis. Fifty eight percent of the trout sample were infected with the acanthocephalan and the mean abundance (+/- SD) was 3.1 +/- 5.1 The relationships between the prevalence and abundance of P. laevis and season and site of host capture and host age and sex were explored. As single factors one of these parameters emerged as significant contributions to changes in parasite abundance although some interaction terms proved to the significant. A random sample of over 700 P. laevis parasites were subjected to further investigation and their size, position in the intestine and maturity status are described. Parasites attained an average weight of 7 mg and occupied the posteriad positions within the fish intestine (77%). Parasites from this sample of Irish brown trout attained a similar average size to those found in chub and barbel from England. 42.3% of the total parasites examined contained ovarian balls only and 17% contained fully mature acanthors. Therefore only a moderate proportion of female worms contained mature acanthors in these trout whereas the majority of worms recovered from a sample of chub were gravid. Utilizing a logistic regression model, parasite size, season, and site of host capture emerged as particularly significant factors which contribute to whether a parasite contains mature eggs.

Abstract
During mitosis the lamins are found in a hyperphosphorylated and soluble state. p34cdc2 kinase (MPF), a protein kinase complex with a pivotal role during mitosis, has been found to phosphorylate the lamins and, in some cases, though not all, to cause depolymerization of the lamina in vitro. Due to the variety of protein interactions in the lamina, there is a probable requirement for multiple enzyme activities to effect its breakdown in mitosis. Using nuclear ghosts as substrate, we have fractionated a Xenopus mitotic extract into a lamin-releasing fraction (p34cdc2 kinase) and a fraction that inhibits p34cdc2 kinase-mediated lamin release if the nuclear ghosts are first preincubated in it. The lamin-release-inhibiting activity in the p34cdc2 kinase-depleted mitotic extract is, in turn, inhibited if PKI, a protein kinase inhibitor specific for PKA, is included in the preincubation reaction mixture. Furthermore, a similar degree of inhibition can be achieved by using purified PKA to preincubate the nuclear ghosts. This suggests that dephosphorylation of PKA substrate sites is necessary for lamin depolymerization.

Abstract
The bag cell neurons of Aplysia californica synthesize and secrete several neuropeptides. To gain more detailed information about their posttranslational routing and transport, we have undertaken isolation of the neurosecretory granules (NSG). Extracts of radiolabeled cells were subjected to discontinuous, isosmotic density-gradient centrifugation. Radiolabeled peptides likely to be contained in NSG were found to relocate from the starting zone and to be associated with particulate structures. Assay of enzyme markers for lysosomes and endoplasmic reticulum disclosed gradient distributions that differed from that shown by the peptides. Hence, it is probable that the position of peak concentrations of particulate peptides represents the location of NSG. Of particular interest is the further observation that the known secretory peptides ELH and AP do not evidence strict covariance across the gradient. This deviation from covariance is consistent with hypotheses that the peptides are in different associations with the NSG cores or that more than one type of neurosecretory granule is produced in the bag cells.
