Expanding urological services into regional Australia and reducing interhospital transfers: how the nurse practitioner can help.

BACKGROUND: A visiting urology service has been in existence at Hamilton Base Hospital, Western Victoria, over the past 25 years, serving an unmet need. A Urology Nurse Practitioner (UNP) provides the care and management of urology patients working in close association with visiting urologists. We aim to assess the impact of the UNP's role in the delivery of regional urological care. METHODS: A retrospective analysis of medical records identified all clinical interventions by the UNP between January 2016 and December 2019. Each encounter was graded according to a clinical severity scale from grade 1 to 5 and assessed for UNP management of patients and the prevention of interhospital transfers. RESULTS: One hundred eighty-four patients with 654 individual assessments were identified for inclusion and classified according to the adapted clinical severity scale. Most interventions for category 3 and 4 patients related to major bleeding, catheter difficulties, and haemodynamic instability. A total of 19 patients whose urological issues would typically require interhospital transfer were able to be managed locally. CONCLUSIONS: Transferring an acute patient from a regional to a tertiary hospital for specialist care is often necessary but not ideal for the patient and their family. The presence of a dedicated UNP in a regional centre is important for patient care and has an important role in preventing unnecessary transfers. This is a vital component of a visiting urological service to a rural community.

Comparison of greenhouse gas emissions from sheep measured using both respiration and portable accumulation chambers.

Methane (CH4) is a potent gas produced by ruminants, and new measurement techniques are required to generate large datasets suitable for genetic analysis. One such technique are portable accumulation chambers (PAC), a short-term sampling method. The objectives of the current study were to explore the relationship between CH4 and carbon dioxide (CO2) output measured using both PAC and respiration chambers (RC) in growing lambs, and separately investigate the relationship among CH4, CO2 and measured ad libitum DM intake (DMI). Methane, CO2 and DMI were measured on 30 Suffolk and 30 Texel ewe lambs (age 253 ± 12 days) using the RC and PAC sequentially. The experiment was conducted over a 14-day period, with DMI measured from days 1 to 14; measurements in RC were conducted from days 10 to 12, while measurements in PAC were taken twice, the day immediately prior to the lambs entering the RC (day 9; PAC Pre-RC) and on the day lambs exited the RC (day 13; PAC Post-RC). Greater CH4 and CO2 output was measured in the RC than in the PAC (P < 0.01); similarly mean CH4 yield was greater when measured in the RC (15.39 ± 0.452 g CH4/kg DMI) compared to PAC (8.01 ± 0.767 g CH4/kg DMI). A moderate correlation of 0.37 was found between CH4 output measured in PAC Pre-RC and the RC, the corresponding regression coefficient of CH4 output measured in the RC regressed on CH4 output measured in PAC Pre-RC was close to unity (0.74; SE 0.224). The variance of CH4 and CO2 output within the measurement technique did not differ from each other (P > 0.05). Moderate to strong correlations were found between CH4 and CO2 per kg of live weight and CH4 and CO2 yield. Results from this study highlight the suitability of PAC as a ranking tool to rank animals based on their gaseous output when compared to the RC. However, repeated measurements separated by several days may be beneficial if precise rankings are required. Given the close to unity regression coefficient of CH4 output measured in the RC regressed on CH4 output measured in PAC Pre-RC suggests that PAC could also be potentially used to estimate absolute CH4 output; however, further research is required to substantiate this claim. When DMI is unknown, CH4 and CO2 per kg of live weight are a suitable alternative to the measurement of CH4 and CO2 yield.

The relationship between ultrasound microcalcifications and psammoma bodies in thyroid tumours: a single-institution retrospective study.

AIM: To investigate the diagnostic accuracy of ultrasound microcalcifications for the detection of malignancy in thyroid nodules and determine the validity of the concept that ultrasound microcalcification reflects the presence of psammoma body calcification in thyroid nodules. MATERIALS AND METHODS: The laboratory information system at University Hospital Galway, a tertiary referral hospital, was used to compile a list of patients who underwent thyroid lobectomy or complete thyroidectomy over a continuous 12-month period with both preoperative ultrasound and postoperative histology available (n=106) from January to December 2019. The haematoxylin and eosin-stained histology slides of each case were sourced and reviewed under light microscopy by a histopathologist to determine the presence of psammoma body calcification within both benign and malignant thyroid nodules. Two radiologists reviewed preoperative thyroid ultrasound images of each case independently and blindly, and reported on the presence of ultrasonographic microcalcification. RESULTS: There was a strong and significant relationship between the presence of preoperative ultrasound microcalcification and thyroid malignancy (p<0.001). Ultrasound microcalcification had a high specificity (93%) and positive predictive value (75%) for thyroid malignancy, with a diagnostic accuracy of 76%. Negative predictive value was high at 76.7%, while sensitivity was low at 42.8%. There was a strong and significant association between the presence of preoperative ultrasound microcalcification in thyroid nodules and the presence of pathological psammoma bodies on histology (p<0.001). DISCUSSION: Ultrasound microcalcification has a strong and significant association with malignancy in thyroid nodules. This study supported the theory that ultrasound microcalcification occurs secondary to the presence of psammoma bodies within thyroid nodules.

Frozen-section examination in the management of paediatric testicular lesions.

PURPOSE: Paediatric testicular and para-testicular lesions have traditionally been managed according to adult protocols. Testis-sparing surgery (TSS) has gained popularity as it has become apparent benign lesions predominate in childhood. Frozen-section examination (FSE) for intra-operative diagnosis has been extensively utilised in adults, though its use in paediatric practice remains limited. We reviewed our experience of FSE in paediatric patients with an aim to identify the utility and efficacy of this tool in the management of testicular and para-testicular pathology. METHODS: A retrospective, single-centre review of paediatric patients who underwent intra-operative FSE for a range of testicular and para-testicular lesions was performed. FSE results were compared to final pathology. TSS was performed if appropriate, and was utilised in adolescent patients, and in lesions with a diameter greater than 20 mm. RESULTS: Nine males underwent FSE from 2013 to 2020. Median age at surgery was 9 years (range 1-15). Eight (89%) patients had benign pathology. FSE result correlated with the final pathological examination in 100% of cases. FSE facilitated TSS in 7/9 cases. CONCLUSION: FSE has 100% diagnostic accuracy for paediatric testicular and para-testicular pathology. We would recommend all lesions be evaluated by FSE to guide intra-operative decision making and facilitate TSS in appropriate cases.

Does instillation of lidocaine gel following flexible cystoscopy decrease the severity of post procedure symptoms? A randomised controlled trial assessing the efficacy of lidocaine gel post flexible cystoscopy.

OBJECTIVE: To assess whether instillation of lidocaine gel both before and after flexible cystoscopy is more effective at reducing post procedural symptoms than instillation of lidocaine gel pre flexible cystoscopy alone. We hypothesise that inadequate urethral dwell time and dilution of lidocaine gel by the irrigation fluid during flexible cystoscopy limits its anaesthetic efficacy. Only one other study has attempted to reduce bothersome urinary symptoms through an intervention after flexible cystoscopy. METHODS: This was a randomised controlled trial in which patients were randomised 1:1 to receive lidocaine gel pre and post flexible cystoscopy (treatment) or lidocaine gel pre flexible cystoscopy only (control). Patient-reported outcome measures were used to assess symptoms and quality of life prior to cystoscopy, on day 2 and day 7 post cystoscopy. RESULT: Fifty patients were divided equally between the treatment and control groups. There were no significant differences in baseline characteristics between the groups (p = 1.000). An overall symptoms variable was measured, though no significant difference was found in the distribution of responses between the groups at baseline, 2 or 7 days after the flexible cystoscopy (p = 0.423, 0.651,0.735). In the treatment group, 1 patient (4.0%) presented to a doctor for review following flexible cystoscopy, and 4 patients (16.0%) presented in the control group (p = 0.349). CONCLUSION: Initial study results suggest that post-operative lidocaine does not significantly limit the exacerbation of urinary symptoms following flexible cystoscopy; however, our results are not powered to detect a small difference. We do not recommend a change in practice based on our results.

Joint action malnutrition in the elderly (MaNuEL) knowledge hub: summary of project findings.

PURPOSE: The Joint Action Malnutrition in the Elderly (MaNuEL) Knowledge Hub was established to extend scientific knowledge, strengthen evidence-based practice, build a sustainable, transnational network of experts and harmonize research and clinical practice in the field of protein-energy malnutrition in older persons. This paper aims to summarize the main scientific results achieved during the 2-year project and to outline the recommendations derived. METHODS: 22 research groups from seven countries (Austria, France, Germany, Ireland, Spain, The Netherlands and New Zealand) worked together on 6 relevant domains of malnutrition-i.e. prevalence, screening, determinants, treatment, policy measures and education for health care professionals-making use of existing datasets, evidence and expert knowledge. RESULTS: Four systematic reviews, six secondary data analyses of existing cohort and intervention studies, two web-based surveys and one Delphi study were performed. In addition, a scoring system to rate malnutrition screening tools and a theoretical framework on the aetiology of malnutrition in older persons were developed. Based on these activities and taking existing evidence into consideration, 13 clinical practice, 9 research and 4 policy recommendations were developed. The MaNuEL Toolbox was created and made available to effectively distribute and disseminate the MaNuEL results and recommendations. CONCLUSIONS: The MaNuEL Knowledge Hub successfully achieved its aims. Results and recommendations will support researchers, healthcare professionals, policy-makers as well as educational institutes to advance their efforts in tackling the increasing problem of protein-energy malnutrition in the older population.

Robotic prostatectomy after abandoned open radical prostatectomy-Technical aspects and outcomes.

Objective: To describe the technical aspects and outcomes of robotic-assisted radical prostatectomy (RARP) following abandoned open radical prostatectomy (ORP). Patients and Methods: A retrospective review was performed of patients who underwent RARP following abandonment of ORP between 2016 and 2020. RARP was undertaken by two highly experienced robotic surgeons. Analysis of patient and operative characteristics, outcomes, and reasons for abandonment of ORP were described. Results: Six patients were included for analysis with a median age of 63.5 years [50.3-67.5]. The median body mass index (BMI) was 34.7 [27.8-36.2]. All patients had intermediate-risk prostate cancer. Small prostate and deep pelvis were given as reasons for abandoning ORP in five cases (83.3%), with four of these also attributing increased BMI as a factor. Extensive mesh from previous bilateral inguinal hernia repair was cited as the reason for abandonment in the remaining patient. One patient had commenced androgen deprivation therapy following abandoned ORP. Extensive retropubic adhesions were noted at the time of RARP in five of six patients, with intraoperative complication of small bladder lacerations encountered in the patient with prior mesh hernia repair. The median time from abandoned ORP to RARP was 128 days [40-216]. Median operating time was 160 minutes [139-190] and estimated blood loss was 225 mL [138-375]. Negative margins were obtained in four of six cases, with further salvage treatment being required in one case at a median follow-up duration of 10.5 months [6.5-25.3]. Conclusion: Abandonment of ORP is an uncommonly reported event, however, in this small case series, we demonstrate that, in the hands of experienced surgeons, RARP is a safe and technically feasible alternative in such cases. Increased BMI, small prostate size and pelvic anatomical constraints appear to be common catalysts for abandonment of open surgery in this cohort. Identifying these high-risk patients early and considering referral to robotic centers may be preferred.

Potentially modifiable determinants of malnutrition in older adults: A systematic review.

BACKGROUND & AIMS: Malnutrition in older adults results in significant personal, social, and economic burden. To combat this complex, multifactorial issue, evidence-based knowledge is needed on the modifiable determinants of malnutrition. Systematic reviews of prospective studies are lacking in this area; therefore, the aim of this systematic review was to investigate the modifiable determinants of malnutrition in older adults. METHODS: A systematic approach was taken to conduct this review. Eight databases were searched. Prospective cohort studies with participants of a mean age of 65 years or over were included. Studies were required to measure at least one determinant at baseline and malnutrition as outcome at follow-up. Study quality was assessed using a modified version of the Quality in Prognosis Studies (QUIPS) tool. Pooling of data in a meta-analysis was not possible therefore the findings of each study were synthesized narratively. A descriptive synthesis of studies was used to present results due the heterogeneity of population source and setting, definitions of determinants and outcomes. Consistency of findings was assessed using the schema: strong evidence, moderate evidence, low evidence, and conflicting evidence. RESULTS: Twenty-three studies were included in the final review. Thirty potentially modifiable determinants across seven domains (oral, psychosocial, medication and care, health, physical function, lifestyle, eating) were included. The majority of studies had a high risk of bias and were of a low quality. There is moderate evidence that hospitalisation, eating dependency, poor self-perceived health, poor physical function and poor appetite are determinants of malnutrition. Moderate evidence suggests that chewing difficulties, mouth pain, gum issues co-morbidity, visual and hearing impairments, smoking status, alcohol consumption and physical activity levels, complaints about taste of food and specific nutrient intake are not determinants of malnutrition. There is low evidence that loss of interest in life, access to meals and wheels, and modified texture diets are determinants of malnutrition. Furthermore, there is low evidence that psychological distress, anxiety, loneliness, access to transport and wellbeing, hunger and thirst are not determinants of malnutrition. There appears to be conflicting evidence that dental status, swallowing, cognitive function, depression, residential status, medication intake and/or polypharmacy, constipation, periodontal disease are determinants of malnutrition. CONCLUSION: There are multiple potentially modifiable determinants of malnutrition however strong robust evidence is lacking for the majority of determinants. Better prospective cohort studies are required. With an increasingly ageing population, targeting modifiable factors will be crucial to the effective treatment and prevention of malnutrition.

The Predictive Ability of Pre-Operative Magnetic Resonance Imaging to Detect Pathological Outcomes in Prostate Cancer

Aims Accurate preoperative knowledge of tumour stage is important in preoperative planning at radical prostatectomy (RP). The aim of this study was to assess the predictive ability of multiparametric MRI for detecting pathological outcomes. Methods A retrospective review was performed of all patients who underwent RP over a 4 year period. Results Preoperative MRI was reported as showing T3 or T4 disease in 26(17.9%) out of 145 patients undergoing RP. Of these, 10(6.9%) had ECE (extra-capsular extension) and 1(0.7%) had SVI (seminal vesicle invasion) on final histology. The sensitivity and specificity of MRI for detecting ECE were 27.3% and 87.6%, respectively. The sensitivity and specificity of MRI for detecting SVI were 11.1% and 97.8%, respectively. The positive predictive values for determining ECE and SVI were 45.5% and 25%, respectively and negative predictive values were 75.9% and 94.4%. Conclusion MRI has good specificity but poor and heterogeneous sensitivity for predicting T3 disease in RP specimen.

Comparison of nomograms predicting lymph node invasion in patients undergoing radical prostatectomy for prostate cancer.

INTRODUCTION: The aim of this study was to compare the performance of preoperative risk nomograms or detecting lymph node invasion in a cohort of men undergoing radical prostatectomy (RP). METHODS: A retrospective analysis was performed on all men (n = 145) who underwent RP between 2012 and 2015. Preoperative data was inputted to the Memorial Sloan-Kettering Cancer Centre (MSKCC), Partin 2011 and Briganti nomograms and the University of California San Francisco- Centre of the Prostate Risk Assessment tool (UCSF-CAPRA). The risk of lymph node involvement (LNI) was calculated and compared to final histology. RESULTS: One hundred three (71%) men underwent a lymph node dissection at RP. Ten (9.7%) demonstrated LNI. The median nodal yield was 15 nodes, with no difference between those with LNI and those without (19.5 vs 14.5, p = 0.22).No patient classified as low risk on the UCSF-CAPRA score had evidence of LNI. In patients with LNI, no patient breached the 2% threshold for lymph node dissection (LND) on the MSKCC nomogram; four patients breached the 5% threshold on the Partin tables while three patients breached the 2.5% threshold for the Briganti nomogram. CONCLUSION: Nomograms produce useful information regarding risk of disease; however, they often have not been validated on different populations. Risk predictions need to be considered carefully and treatment decisions were made on a patient specific basis.

Palliative and end of life care in solid organ transplantation.

Palliative care is an interprofessional approach that focuses on quality of life of patients who are facing life-threatening illness. Palliative care is consistently associated with improvements in advance care planning, patient and caregiver satisfaction, quality of life, symptom burden, and lower healthcare utilization. Most transplant patients have advanced chronic disease, significant symptom burden, and mortality awaiting transplant. Transplantation introduces new risks including perioperative death, organ rejection, infection, renal insufficiency, and malignancy. Numerous publications over the last decade identify that palliative care is well-suited to support these patients and their caregivers, yet access to palliative care and research within this population are lacking. This review describes palliative care and summarizes existing research supporting palliative intervention in advanced organ failure and transplant populations. A proposed model to provide palliative care in parallel with disease-directed therapy in a transplant program has the potential to improve symptom burden, quality of life, and healthcare utilization. Further studies are needed to elucidate specific benefits of palliative care for this population. In addition, there is a tremendous need for education, specifically for clinicians, patients, and families, to improve understanding of palliative care and its benefits for patients with advanced disease.

An Analysis of Gender Diversity in Urology in the UK and Ireland.

Traditionally, surgery and certain surgical sub-specialities in particular have been predominantly male orientated. In recent years, there has been an increased proportion of female medical graduates which will ultimately have an effect on speciality choices. The aim of this study was to assess the gender diversity among urologists in the UK and Ireland. The total number and gender breakdown of consultant urologists and trainees in the UK and Ireland was obtained from the British Association of Urological Surgeons (BAUS) and the Irish Society of Urology (ISU) membership offices. The total number and gender breakdown of medical school entrants and graduates in 2015 was obtained from the six medical schools in the Republic of Ireland. There are a total of 1,012 consultant urologists in the UK and Ireland. In the UK, 141 (14.6%) are female compared to four (8.2%) in Ireland, p= 0.531. There was a significant increase in the number of females between consultant urologists and trainees in both the UK (p=0.0001) and Ireland (p=0.015). In recent years, there has been a significant change in the percentage of female trainees in the UK and Ireland (22.8% (n=75) in 2011 vs 31.7% (n=93) in 2014, p=0.019. Between the six medical schools in Ireland, there were significantly more female entrants (n=726, 56.5%) than female graduates (n=521, 51.2%) in 2015, p=0.013.There has been a significant shift in gender diversity in urology in the UK and Ireland. Efforts to increase diversity should be pursued to attract further trainees to urology.

The role of laparoscopic sleeve gastrectomy as a treatment for morbid obesity; review of outcomes.

BACKGROUND: Global prevalence of obesity has soared. Where lifestyle and medical treatments have failed, laparoscopic sleeve gastrectomy (LSG) is increasingly regarded as a good surgical procedure for morbid obesity. Following the introduction of LSG, we assessed our surgical outcomes. METHODS: We reviewed a consecutive series of LSGs from January 2009 to January 2015. Our primary focus was to assess the success of this procedure on the percentage excess body weight loss (%EWL), Body Mass Index (BMI), hypertension and diabetes. Additionally, we evaluated the rate of procedure-related complications. RESULTS: There were 183 consecutive patients evaluated. Median age was 45 years (24-73). The majority were female (73.2 %, n = 134). At 1 year post-op, median %EWL was 57.6 %. There was an associated median reduction in BMI of 16 kg/m2 (0-33). At 2 years, median %EWL was sustained at 58.4 %. The median reduction in BMI was 16 kg/m2 (4-32). At 2-year post-op, 78.9 % of diabetic patients had their diabetic medications completely discontinued, while a further 15.8 % having their medication reduced. 34.6 % of hypertensive patients had their antihypertensives discontinued, with 50 % having medications reduced. There was no procedure related mortality. 3.3 % (n = 6) of patients had a confirmed staple-line leak. CONCLUSION: This study shows LSG is a safe and successful management strategy for morbid obesity. In addition to the direct effects of sustained weight loss, it highlights indirect effects that LSG has on obesity-related health issues, with substantial reduction in diabetic and anti-hypertensive medications. Our results reaffirm international studies of the beneficial effects of LSG on Type II diabetes and hypertension.

Study of the apoptotic effect of urine as a diagnostic biomarker in patients with interstitial cystitis. / Estudio del efecto apoptótico de la orina de pacientes con cistitis intersticial como biomarcador diagnóstico.

INTRODUCTION: The main objective of the study was to assess the apoptotic effect of urine from patients with interstitial cystitis (IC) in cell cultures and to study its value as a diagnostic biomarker for IC. MATERIAL AND METHODS: A prospective study was conducted between January 2010 and January 2015 and included 57 patients diagnosed with IC and 50 healthy patients from the Hospital Clinic of Barcelona and the La Paz University Hospital. The urine of these patients was exposed to cell cultures, and its ability to induce apoptosis in the cultures was analysed. Using flow cytometry, we then measured the degree of apoptosis, quantified by the percentage of cells of the cell cycle in phase sub G0. RESULTS: The cell cultures exposed to the urine of patients with IC had a sub G1 peak and a G2 phase, which was significantly greater than that of the control group, and a significantly lower percentage in the S phase than the control group. The mean apoptosis values in the urine cultures from patients with IC were significantly higher than those of the control group. Using a value >10% of the apoptosis test as a positive result, we observed a specificity of 96% and a positive predictive value of 92%. CONCLUSIONS: The urine of patients with IC exerts an apoptotic effect on tumour cell cultures that is significantly greater than that exerted by the urine of healthy control patients. A≥10% cutoff for the apoptosis test presented very low sensitivity (40%) but had a very high specificity (96%), thereby able to confirm the diagnosis of IC when positive.

The evolution of highly variable immunity genes across a passerine bird radiation.

To survive, individuals must be able to recognize and eliminate pathogens. The genes of the major histocompatibility complex (MHC) play an essential role in this process in vertebrates as their diversity affects the repertoire of pathogens that can be recognized by the immune system. Emerging evidence suggests that birds within the parvorder Passerida possess an exceptionally high number of MHC genes. However, this has yet to be directly investigated using a consistent framework, and the question of how this MHC diversity has evolved has not been addressed. We used next-generation sequencing to investigate how MHC class I gene copy number and sequence diversity varies across the Passerida radiation using twelve species chosen to represent the phylogenetic range of this group. Additionally, we performed phylogenetic analyses on this data to identify, for the first time, the evolutionary model that best describes how MHC class I gene diversity has evolved within Passerida. We found evidence of multiple MHC class I genes in every family tested, with an extremely broad range in gene copy number across Passerida. There was a strong phylogenetic signal in MHC gene copy number and diversity, and these traits appear to have evolved through a process of Brownian motion in the species studied, that is following the pattern of genetic drift or fluctuating selection, as opposed to towards a single optimal value or through evolutionary 'bursts'. By characterizing MHC class I gene diversity across Passerida in a systematic framework, this study provides a first step towards understanding this huge variation.

Replantation of digits: a review of predictive factors for survival.

UNLABELLED: The survival of 75 consecutive digital replantations carried out between 2006 and 2010 at a regional hand centre in the United Kingdom was determined. The patient demographics, mechanism of injury, co-morbid factors, operative and post-operative details were extracted and reviewed from the medical and hand therapy notes. Predictive factors of survival were determined by using univariate and multivariate statistical analysis. The survival rate was 70%. Arterial thrombosis was the leading cause of replant failure, followed by venous congestion. Smoking, level of amputation, number of nerves repaired, warm ischaemia time and timing of replantation were independent predictors of replant survival. However, only warm ischaemia time less than 6 hours and 30 minutes and replantations done within 'office hours' showed significance on multivariate logistic regression. Our study suggests that replantations done in daylight hours, when feasible, with rested staff and a full complement of the theatre team are likely to have better outcomes. LEVEL OF EVIDENCE: Level IV case series.

The free instep flap for palmar and digital resurfacing.

The palmar and digital volar skin is unique because of its glabrous nature, texture and light colour in all races. Any defect on the palmar surface not suitable for a homodigital or thenar flap remains a challenge for reconstructive surgeons. Various skin flaps have been described in the literature for palmar resurfacing. They all provide wound cover and may even match the contour satisfactorily, however, the colour and texture mismatch compromises the aesthetics of reconstruction. In our experience, the free instep flap is a more appropriate choice for palmar and volar digital resurfacing. It provides glabrous, potentially sensate, hairless skin with a better colour and texture match compared to conventional pedicled or free flaps in all cases. This paper describes our refined flap raising technique, the possibility of a neurotisation and discusses the role of the free instep flap for idealised digital and palmar resurfacing. It can provide a truly cosmetic microsurgical reconstructive option.

Factitious hand disorders: review of 29 years of multidisciplinary care.

PURPOSE: To improve our understanding of factitious hand disorders with a review of our experience over 29 years in a multidisciplinary hand center. METHODS: A retrospective chart review was performed to identify workers' compensation patients treated for factitious hand disorders in the multidisciplinary hand center between January 1981 and September 2010. Multidisciplinary evaluation at this center involved evaluation by hand surgeons, occupational therapists, and psychologists. Data collected include age, sex, race, educational level, clinical presentation, number of diagnostic tests, number of surgeries, time to referral to the multidisciplinary center, direct cost of care, psychological diagnosis, Minnesota Multiphasic Personality Inventory, treatment modalities, and work status. RESULTS: We identified 174 workers' compensation patients with factitious hand disorders. Presentation was used to classify patients into 1 of 4 categories: psychopathological dystonia, factitious edema, psychopathological complex regional pain syndrome, and factitious wound creation and manipulation. There were statistically significant differences between the 4 categories in demographics, utilization of medical resources, psychopathology, treatment modalities, and return-to-work status. Patients with factitious wounds were more educated, used more medical resources, demonstrated an angry or hostile profile, and experienced a lower return-to-work rate. Patients with dystonia were less educated, used less medical resources, demonstrated a hypochondriasis or depressed profile, and experienced a higher return-to-work rate. CONCLUSIONS: Treatment of factitious hand disorders remains frustrating and costly due to failure or recurrence after traditional approaches. This review is a large-scale examination of the factitious hand disorder population that demonstrates the unique pathology involved in each of the 4 categories. There is a specific association between the category of hand disorder and the underlying pathology and prognosis. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

The transnasal flexible laryngoesophagoscope as an adjunct during surgical correction of choanal atresia.

INTRODUCTION: We report the first published description of transoral use of the transnasal flexible laryngoesophagoscope during surgical correction of choanal atresia. CASE REPORT: A four-month-old boy was referred to the ear, nose and throat department by his general practitioner with a two-week history of left-sided, watery, green, nasal discharge. A diagnosis of choanal atresia was made. The child underwent successful surgical correction which incorporated transoral use of a transnasal flexible laryngoesophagoscope. DISCUSSION: When used transorally, the transnasal flexible laryngoesophagoscope's ability to provide omnidirectional visualisation together with high definition picture clarity significantly improves the operative field of view. This endoscope's incorporated suction and insufflation functions and its facility to pass extra instruments via the endoscope port are of particular advantage for this type of procedure.
