The impact of single-use digital flexible cystoscope for double J removal on hospital costs and work organization: A multicentric evaluation.

BACKGROUND: Isiris-α® is a single-use digital flexible cystoscope with an integrated grasper designed for double J (DJ) stent removal. Aim of this study was to conduct a multicentric evaluation of the costs and criticalities of stent removals performed with Isiris®-α in different hospitals and health systems, as compared to other DJ removal procedures. METHODS: After gathering 10 institutions worldwide with experience on Isiris-α®, we performed an analysis of the reported costs of DJ removal with Isiris-α®, as compared to the traditional reusable equipment used in each institution. The cost evaluation included instrument purchase, Endoscopic Room (EnR)/ Operatory Room (OR) occupancy, medical staff, instrument disposal, maintenance, repairs, decontamination or sterilization of reusable devices. RESULTS: The main factor affecting the costs of the procedure was OR/EnR occupancy. Decontamination and sterilization accounted for a less important part of total costs. Isiris-α® was more profitable in institutions where DJ removal is usually performed in the EnR/OR, allowing to transfer the procedure to outpatient clinic, with a significant cost saving and EnR/OR time saving to be allocated to other activities. In the only institution where DJ removal was already performed in outpatient clinics, there is a slight cost difference in favor of reusable instruments in high-volume institutions, given a sufficient number to guarantee the turnover. CONCLUSION: Isiris-α® leads to significant cost benefit in the institutions where DJ removal is routinely performed in EnR/OR, and brings significant improvement in organization, cost impact and turnover.

Assessment and management of shoulder pain at primary care level.

Most patients with shoulder pain will initially visit their community health centre, private general practitioner or family physician, with various levels of experience in the assessment and management of shoulder conditions. Shoulder conditions will range from early, simple ailments that can be treated in the primary care setting, to post-traumatic injuries and complex pathologies requiring the expertise of an orthopaedic surgeon or a fellowship-trained shoulder surgeon. Correct assessment of the patient's shoulder condition at the index consultation is a prerequisite for appropriate management. This article sets out straightforward guidelines to help general practitioners confidently identify the patient's source of shoulder pain and initiate an appropriate management plan at primary care level. Criteria for urgent and elective referral for specialist care are also outlined.

Isiris™ for Ureteric Stent Removal in Renal Transplantation: An Initial Single-Centre Experience of 150 Cases.

Background. Ureteric stent insertion is performed at the time of renal transplant to minimise the risk of post-operative urological complications, including anastomotic leak and ureteric stenosis or obstruction. Transplant ureteric stent removal (TUSR) has historically been performed via flexible cystoscopy, predominantly in a theatre setting. Isiris™ is a single-use cystoscope with integrated grasper designed for removal of ureteric stents. We report our initial experience. Methods. A retrospective analysis of a contemporaneously maintained database was performed with review of case notes from October 2017 to September 2018. TUSR was performed by surgical middle grades with a single nurse assistant. Results. One hundred and fifty ureteric stents were removed in transplant recipients (mean age 50.2 years, SD ± 15.2; 61.3% male). 91.3% (n = 137) of cases were performed in the outpatient clinic. Median time to TUSR was 42 days (IQR 30-42). 147 attempts at removal were successful. One urinary tract infection (UTI) was reported following TUSR. Use of the Isiris™ for TUSR corresponds to a £63,480 saving in this cohort compared to conventional practice. This value is conservative and does not include income that has been gained from the reallocation of operating theatre capacity. Conclusion. Isiris™ can safely be employed for the timely performance of non-complicated TUSR. Isiris™ releases this procedure from the confines of the operating theatre to the outpatient clinic. This reduces the resource burden for healthcare providers and may result in improved patient satisfaction. The environmental implications of disposable healthcare equipment require consideration. Evaluation of Isiris™ TUSR for encrustation is required.

11ß-hydroxysteroid dehydrogenase type 1 inhibitor use in human disease-a systematic review and narrative synthesis.

INTRODUCTION: 11ß-hydroxysteroid dehydrogenase type 1 (11ß-HSD1) is an intracellular enzyme that catalyses conversion of cortisone into cortisol; correspondingly, 11ß-HSD1 inhibitors inhibit this conversion. This systematic review focuses on the use of 11ß-HSD1 inhibitors in diseases known to be associated with abnormalities in hypothalamic pituitary adrenal (HPA) axis function. METHODS: The databases screened for suitable papers were: MedLine, EMBASE, Web of Science, ClinicalTrials.gov, and Cochrane Central. RESULTS: 1925 papers were identified, of which 29 were included in the final narrative synthesis. 11ß-HSD1 and its inhibitors have been studied in diabetes, obesity, metabolic syndrome (MetS), and Alzheimer's disease (AD). Higher expression of 11ß-HSD1 is seen in obesity and MetS, but has not yet been described in obesity or AD. Genetic studies identify 11ß-HSD1 SNPs of interest in populations with diabetes, MetS, and AD. One phase II trial successfully reduced HbA1c in a diabetic population, however trials in MetS, obesity, and AD have not met primary endpoints. CONCLUSIONS: Translation of this research from preclinical studies has proved challenging so far, however this is a growing area of research and more studies should focus on understanding the complex relationships between 11ß-HSD1 and disease pathology, especially given the therapeutic potential of 11ß-HSD1 inhibitors in development.

Office-based ureteric stent removal is achievable, improves clinical flexibility and quality of care, whilst also keeping surgeons close to their patients.

INTRODUCTION: Diagnostic pressure on endoscopy suites can result in stent removal not receiving the required priority and unnecessary morbidity for patients. As well as using stents with extraction strings, the introduction of a portable single-use flexible cystoscope for ureteric stent removal (Isiris™), offered an opportunity to negotiate these issues by relocating stent removal to the office/clinic. This study aimed to determine whether such flexibility reduced stent dwell time with the assumption this would improve patient experience and decrease associated complications. MATERIALS AND METHODS: A retrospective review of ureteric stents placed during stone procedures was undertaken. Data collection included; patient demographics; stent dwell times; the number of emergency department (ED) attendances and hospital readmissions; procedure cancellation rates and the number of urinary tract infections. RESULTS: In total, 162 stents were removed (113 Standard, 34 Isiris™, 15 via strings). Excess dwell time was reduced in both Isiris™ (median 1 day, mean 1.37 days, p = 0.0009) and Strings Groups (median 0.96 days, mean 0.96 days, p = 0.022) compared with the Standard Group (median 8 days, mean 15.34 days).ED attendances and readmissions were reduced by 33.5% and 22% respectively in the Isiris™ Group compared with the Standard Group. There were no ED attendances in the Strings Group. Reductions in length of stay, urine infections and cancellation on the day of procedures were also observed. CONCLUSIONS: The clinical flexibility provided by Isiris™ and 'stents on strings' has objectively improved patient experience and is associated with a reduction in complications as well as increasing diagnostic capacity and cost efficacy.

Humeral Stem Loosening Following Reverse Shoulder Arthroplasty: A Systematic Review and Meta-Analysis.

BACKGROUND: Aseptic stem loosening following reverse shoulder arthroplasty (RSA) is an uncommon complication. The timing and the factors contributing to aseptic stem loosening remain poorly understood. METHODS: We performed a systematic review that identified 75 articles; 65 of the included articles were case series (Level-IV evidence), 8 were cohort studies (7 Level III, 1 Level II), and 2 were prospective randomized controlled trials (Level I). A meta-analysis of 1,660 cemented and 805 uncemented RSA stems was performed. We compared the rates of aseptic stem loosening, humeral radiolucent lines, and revision for stem loosening (1) between cemented and uncemented stems in cohorts with short and long mean follow-up periods (<5 and ≥5 years) as well as in all cohorts combined, and (2) among different etiological subgroups. RESULTS: Aseptic stem loosening occurred more commonly in the cohort with long compared with short follow-up time (2% versus 0.8%, p = 0.01). When comparing cemented with uncemented stems, there was no significant difference in the rates of aseptic stem loosening or revision for stem loosening in either the short or long-term follow-up groups. Humeral radiolucent lines were more common with cemented compared with uncemented stems (15.9% versus 9.5%, p = 0.002). Analyzed by etiology, the highest rate of aseptic stem loosening occurred in the tumor subgroup (10.8%), followed by RSA as a revision procedure after a failed arthroplasty (3.7%). No stems in the acute fracture or fracture sequelae subgroups developed aseptic stem loosening. CONCLUSIONS: Aseptic stem loosening occurred more commonly in cohorts with longer follow-up. There were no differences in the rates of aseptic stem loosening or revision for stem loosening between cemented and uncemented stems. Patients treated with RSA following excision of proximal humeral tumors and RSA as a revision procedure after a failed arthroplasty were at greater risk of aseptic stem loosening. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

The Meaning of the Child Interview: A new procedure for assessing and understanding parent-child relationships of 'at-risk' families.

Reder and Duncan's well-known studies of the 1990s on fatal child abuse drew attention to how parental scripts regarding their children could dangerously distort relationships in ways that were sometimes fatal to children. This article reports on a new system for assessing the 'meaning of the child to the parent', called the Meaning of the Child Interview (MotC). Parents are interviewed using the established Parent Development Interview, or equivalent, and the transcript of the interview is then analysed according to parental sensitivity and likely risk to the child. The MotC constructs were developed from those used in observed parent-child interaction (specifically, the CARE-Index) and the form of discourse analysis used in the Dynamic Maturational Model - Adult Attachment Interview, allowing a more systemic and inter-subjective understanding of parenting representations than often put forward. This article discusses the theoretical background to the MotC, gives a brief review of similar measures and then introduces the coding system and patterns of caregiving. The validity of the MotC is addressed elsewhere.

Tips and tricks of ureteroscopy: consensus statement. Part II. Advanced ureteroscopy.

Our "tips and tricks" focuses on all aspects of upper tract endourology and we hope these will be of use to all trainees and consultants who perform ureteroscopy. We report an "expert consensus view" from experienced endourological surgeons, on all aspects of advanced ureteroscopic techniques, with a particular focus on avoiding and getting out of trouble while performing ureteroscopy. In this paper we provide a summary of placing ureteric access sheath, flexible ureteroscopy, intra renal stone fragmentation and retrieval, maintaining visual clarity and biopsy of ureteric and pelvicalyceal tumours.

Dissolution of extensive urolithiasis: extending the utility of rasburicase can avoid the need for surgical intervention and renal replacement therapy.

A 79-year-old male with chronic myelomonocytic leukaemia and extensive bilateral renal stone disease was treated with intravenous rasburicase for persistent hyperuricaemia. Subsequent imaging revealed a complete dissolution of stone burden, avoiding the need for complex, invasive stone surgery and further renal replacement therapy.

Evaluating the clinical and cost effectiveness of a behaviour change intervention for lowering cardiovascular disease risk for people with severe mental illnesses in primary care (PRIMROSE study): study protocol for a cluster randomised controlled trial.

BACKGROUND: People with severe mental illnesses die up to 20 years earlier than the general population, with cardiovascular disease being the leading cause of death. National guidelines recommend that the physical care of people with severe mental illnesses should be the responsibility of primary care; however, little is known about effective interventions to lower cardiovascular disease risk in this population and setting. Following extensive peer review, funding was secured from the United Kingdom National Institute for Health Research (NIHR) to deliver the proposed study. The aim of the trial is to test the effectiveness of a behavioural intervention to lower cardiovascular disease risk in people with severe mental illnesses in United Kingdom General Practices. METHODS/DESIGN: The study is a cluster randomised controlled trial in 70 GP practices for people with severe mental illnesses, aged 30 to 75 years old, with elevated cardiovascular disease risk factors. The trial will compare the effectiveness of a behavioural intervention designed to lower cardiovascular disease risk and delivered by a practice nurse or healthcare assistant, with standard care offered in General Practice. A total of 350 people will be recruited and followed up at 6 and 12 months. The primary outcome is total cholesterol level at the 12-month follow-up and secondary outcomes include blood pressure, body mass index, waist circumference, smoking status, quality of life, adherence to treatments and services and behavioural measures for diet, physical activity and alcohol use. An economic evaluation will be carried out to determine the cost effectiveness of the intervention compared with standard care. DISCUSSION: The results of this pragmatic trial will provide evidence on the clinical and cost effectiveness of the intervention on lowering total cholesterol and addressing multiple cardiovascular disease risk factors in people with severe mental illnesses in GP Practices. TRIAL REGISTRATION: Current Controlled Trials ISRCTN13762819. Date of Registration: 25 February 2013. Date and Version Number: 27 August 2014 Version 5.

Nephrectomy for benign disease in the UK: results from the British Association of Urological Surgeons nephrectomy database.

OBJECTIVE: To summarize the practice of UK urologists with regard to nephrectomy for benign disease, documenting the indications, procedural techniques and outcomes. METHODS: All patients undergoing nephrectomy for a benign condition in 2012 were identified from the British Association of Urological Surgeons (BAUS) nephrectomy database. Recorded variables included the technique of surgery, the type of minimally invasive procedure, operating time, blood loss, transfusion rate, conversion rate, intra- and postoperative complications and mortality rate. Cases were also sub-analysed according to their pathologies to determine the differences in complication rate between stone disease, pyelonephritis, non-functioning kidney and other benign lesions. To contextualize procedural complexity, the simple nephrectomy data were compared with those obtained from the BAUS stage T1 radical nephrectomy audit. RESULTS: A total of 1 093 nephrectomies were performed (537 non-functioning kidneys, 142 stone disease, 129 nephrectomies secondary to pyelonephritis and 285 cases with other benign conditions). Of these, 76% were performed laparoscopically. Blood loss >500 mL was noted in 74 cases with a 4.8% blood transfusion rate. The intra- and postoperative complication rates were 5.2 and 11.9%, respectively. Of the 847 minimally invasive procedures, the conversion rate was 5.9%. Patients with stone disease have the highest intra- and postoperative complications (9.9 and 23.9%, respectively) compared with other benign pathologies. The total number of T1 radical nephrectomies performed was 1 095. In comparison with T1 radical nephrectomy, simple nephrectomy carries an increased risk of conversion to an open procedure (1.8 times), a higher rate of blood transfusion (4.8 vs 2.8%), and a higher risk of intra- and postoperative complications (5.2 vs 3.7% and 11.9 vs 10%, respectively). CONCLUSION: The present study reports the largest series of nephrectomies performed for benign disease and the resultant data now support the bespoke preoperative counselling of patients. Furthermore, it confirms the commonly held view that simple nephrectomy can be more difficult than its radical counterpart. The authors suggest that the term 'simple nephrectomy' is changed to 'benign nephrectomy'.

Tips and tricks of ureteroscopy: consensus statement Part I. Basic ureteroscopy.

Ureteroscopy is fast becoming the first line treatment option for the majority of urinary tract stones. Ureteroscopy training can be performed in a variety of ways including simulation, hands on ureteroscopy courses and supervised operative experience. We report an "expert consensus view" from experienced endourological surgeons, on all aspects of basic ureteroscopic techniques, with a particular focus on avoiding and getting out of trouble while performing ureteroscopy. In this paper we provide a summary of treatment planning, positioning, cannulation of ureteric orifice, guidewire placement, rigid ureteroscopy and stone fragmentation.

Early fracture stabilisation in the presence of subclinical hypoperfusion.

INTRODUCTION: In polytrauma patients with an injury severity score (ISS)>16, early long bone and pelvic fracture fixation within 24h after injury has been shown to be beneficial. In contrast, surgery in the presence of subclinical hypoperfusion (SCH), defined as normal vital signs with a serum lactate≥2.5mmol/L may be detrimental. This study aimed to investigate the effect of fracture fixation in polytrauma patients with SCH. METHODS: We undertook a database review extracting 88 polytrauma patients with a new injury severity score (NISS)>16 with significant long bone or pelvic fractures (extremity NISS≥9) who underwent surgical fracture stabilisation within 48h of injury. In the group of patients with normal vital signs (mean arterial pressure≥60mmHg and heart rate≤110 beats/min) we compared outcomes between those with a normal preoperative lactate (<2.5mmol/L) and those with a raised lactate (≥2.5mmol/L). RESULTS: Of the 36 patients with normal preoperative vital signs, 17 had normal lactates (control group) and 19 abnormal lactates (SCH group). There were no significant differences in the method of fixation or theatre time between the groups. The SCH group required more inotropic support in the first 24h post surgery (p=0.02) and had higher sequential organ failure assessment (SOFA) scores on day 3 (p=0.003). Although not reaching mathematical significance those with SCH required on average 10 days longer on mechanical ventilation. CONCLUSION: Early fracture fixation in patients with SCH as defined by normal vital signs and a lactate≥2.5mmol/L is associated with significant postoperative morbidity. Consideration should be given to delaying surgery in this cohort.

Fracture stabilisation in a polytraumatised African population--a comparison with international management practice.

INTRODUCTION: Fracture management in polytrauma patients has favoured early definitive fracture fixation with some authors advocating a staged management approach in these potentially unstable patients. We aimed to investigate the timing of surgical fracture stabilisation in polytrauma patients with significant orthopaedic injuries in a Level 1 trauma unit in South Africa (RSA) and to compare its performance with Level 1 trauma units in the USA and Europe. MATERIALS AND METHODS: A retrospective review was performed extracting polytrauma patients with a New Injury Severity Score (NISS) ≥ 15, with significant pelvic or long bone fractures managed surgically. We compared these data with recently published data from the USA and Europe. RESULTS: Over a 3 year period pedestrian (46.3%) and motor vehicle or motorcycle accidents (40.7%) were the predominant mechanisms of injury in the 123 eligible patients. Compared to international data, patients were significantly younger (32.41 years (SD 13.4) vs. USA 44.1 years (SD 16.39) and Germany 41.2 years (SD 15.35), p < 0.001); and had a higher NISS score (RSA 31.93 (10.3), USA 27.4 (8.65), Germany 29.4 (6.88), p = 0.007). Less definitive fixation took place in the first 24h (RSA 37.4%, USA 57.1%, Germany 65.6%, p < 0.001), but overall definitive fixation took place earlier (RSA 3.6 days (SD 4.39), USA 5.5 days (SD 4.2), Germany 6.6 days (SD 8.7), p = 0.001). CONCLUSION: In a developing country when compared to international trauma centres, less primary definitive fixation was performed in the first 24h.

Differential complication rates following radical cystectomy in the irradiated and nonirradiated pelvis.

BACKGROUND: Reports suggest that cystectomy following pelvic irradiation is associated with a higher morbidity and mortality than in primary cases. However, such reports are from an era when postcystectomy complication rates were higher than are currently reported. OBJECTIVE: This study evaluates perioperative complications and mortality in primary radical and postradiation salvage cystectomy. DESIGN, SETTING, AND PARTICIPANTS: Patients treated with cystectomy for bladder cancer or advanced pelvic malignancies involving the bladder were studied. MEASUREMENTS: Perioperative complications and mortality were analysed for 426 primary and 420 salvage cystectomies performed at a single institution between 1970 and 2005. RESULTS AND LIMITATIONS: The 30- and 60-d mortality in the 2000-2005 cohort were 0% and 1.2%, respectively, in the primary group and 1.4% and 4.3%, respectively, in the salvage cystectomy group. Thirty-day mortality between 1970 and 2005 was not statistically significant in the primary and salvage groups (4.2% and 7.1%, respectively). CONCLUSIONS: This large series from a high-volume centre demonstrates no difference in perioperative mortality in primary or postradiation salvage radical cystectomy. Similarly, there was no significant difference in the incidence of most of the surgical or medical complications in either group, although the stomal stenosis rate was higher postradiation.
