Feasibility of using the TOSCA telescreening procedures for diabetic retinopathy

DIABETIC MEDICINE, Issue 10 2004
S. Luzio
Abstract Aims The TOSCA project was set up to establish a tele-ophthalmology service to screen for diabetic retinopathy (DR) in Europe. The aim of this study was to determine the feasibility of establishing telemedicine-based digital screening for detecting DR and to evaluate the satisfaction of both patients and healthcare professionals with the screening procedures used within the TOSCA project. Methods The study was a non-randomized, multicentre study carried out in four different countries over a period of 3 months. Patients (n = 390) with diabetes aged > 12 years were included. Two digital retinal images per eye (macular and nasal) were taken and exported to a central server. Patients were asked to complete a questionnaire to assess satisfaction. Accredited graders carried out grading remotely and the results were reported back to the referring centre. Previously graded patient data chosen randomly to represent examples of both DR and no DR were also sent anonymously to the grading centre at a frequency of approximately every 10 patients. Results Most (99%) of the images were assessable enabling a retinopathy grade to be assigned to the patient. Patients found the retinal photography procedures acceptable; only 6% in one centre would not recommend the procedure. Healthcare professionals (photographers and graders) were also satisfied with the overall procedures. The average time taken to grade each patient was approximately 5 min. Conclusions This study demonstrated that it is feasible to electronically transmit and grade retinal images remotely using the TOSCA process. Built-in quality assurance procedures proved acceptable.

Nephron-sparing surgery: a call for greater application of established techniques

BJU INTERNATIONAL, Issue 10 2008
James G. Young
OBJECTIVES To examine the results of open partial nephrectomy (OPN) over a 15-year period in a large UK teaching hospital and to compare results with other series including minimally invasive techniques, as nephron-sparing techniques are still under-utilized in the surgical treatment of renal carcinoma. A standardized technique is described that we think minimizes the risk of postoperative urinoma. PATIENTS AND METHODS We retrospectively reviewed a series of 141 patients who underwent OPN performed over a 15-year period in one centre by the senior author (D.M.A.W.). A notable feature of this series compared with others is the high proportion of patients undergoing other major synchronous surgery. RESULTS In all, 141 patients underwent 147 OPNs, with six undergoing bilateral procedures, of which 82 were for imperative indications (single kidney, bilateral synchronous tumours, or pre-existing renal impairment). There were three perioperative deaths, two in patients undergoing other synchronous major surgery. In all, 38 patients had postoperative complications: 28 patients required blood transfusion (four required intervention for their bleeding), five required acute dialysis and three late dialysis. There was a 90% cancer-specific survival rate at a median follow-up of 2 years. CONCLUSIONS This series confirms the trend towards improved outcomes and decreased complications in OPN at a time when its place is challenged by minimally invasive techniques. [source]


Open mini-access ureterolithotomy: the treatment of choice for the refractory ureteric stone?

BJU INTERNATIONAL, Issue 6 2003
D.M. Sharma
OBJECTIVE To report the experience in one centre of the efficacy and safety of open mini-access ureterolithotomy (MAU) and to discuss relevant current indications. PATIENTS AND METHODS MAU was undertaken in 112 patients (mean age 38 years, range 26,57) between 1991 and 2001; the details and outcomes are reviewed. The mean (range) stone size was 12 (8,22) mm, with 30 stones in the upper, 69 in the mid- and 13 in the lower ureter. In 15 cases the stones were impacted and there were signs of infection in the proximal ureter. RESULTS MAU was successful in 111 patients; the one failure was caused by proximal stone migration early in the series. The mean (range) operative duration was 28 (10,44) min and the hospital stay 42 (24,72) h; 33 patients were in hospital for 24 h, 72 for 48 h and seven for 72 h. The blood loss was minimal, at 50 (30,150) mL. The drain was removed after 5 (5,7) days. Patients reported using opioid or nonsteroidal anti-inflammatory analgesia for a mean of 4 (1,7) days after surgery. The mean time to resumption of work was 16 (8,35) days. CONCLUSIONS MAU is a safe and reliable minimally invasive procedure; its role is mainly confined to salvage for failed first-line stone treatments but in selected cases, where a poor outcome can be predicted from other methods, it is an excellent first-line treatment.

Quality control in urodynamics: a review of urodynamic traces from one centre

BJU INTERNATIONAL, Issue 3 2003
J. Sullivan
OBJECTIVE To investigate quality control in our unit and to enable other units to compare their results, as experience from central reviews of urodynamic traces for multicentre trials has suggested that poor quality control is common. PATIENTS AND METHODS All consecutive male urodynamic tests conducted over 1 year were reviewed. A list of criteria to assess the quality of the records was devised, based upon International Continence Society guidelines on ,good urodynamic practice', and on other sources. Eligible traces were analysed for aspects of quality control, e.g. baseline pressures and coughs to test pressure transmission. The data were analysed to establish how often quality criteria were met, and identify areas for improvement. RESULTS In 100 eligible traces, the baseline detrusor pressure was 0,10 cmH2O in 86, and , 5 to +10 cmH2O in 94%. Baseline intravesical and abdominal pressure were 30,50 cmH2O in 68% and 73% of cases, respectively. Coughs were present before filling in 94%, during filling in 95%, before voiding in 72% and after voiding in 87% of cases. The cough-test frequency was sufficient in 30% of traces. In 11 the intravesical pressure line fell out during voiding. CONCLUSION Most of the traces assessed met the quality criteria defined, but significant defects were not uncommon. Some of the problems identified suggest areas of urodynamic technique which should be studied in more detail. We intend to modify our quality control practices, and hope to show an improvement on re-audit. We hope that other urodynamic departments will be encouraged to review their practice, and we aim to improve our results. [source]


Mild hypercalcitoninaemia and sporadic thyroid disease,

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 5 2010
M. Cherenko
Background: Not operating on patients with mild hypercalcitoninaemia (MHCT) and sporadic thyroid disease carries the risk of omitting curative surgery for medullary thyroid cancer, but systematic surgery would result in unnecessary treatment of benign pathology. This study reviewed the management of MCHT and non-hereditary thyroid disease in one centre. Methods: MCHT was defined as an increase in basal and stimulated calcitonin levels not exceeding 30 and 200 pg/ml respectively. Over 15 years, 125 patients who presented with MCHT and sporadic thyroid disease were followed. Surgery was indicated only if there were local pressure symptoms or suspicious histomorphological changes in solitary nodules. Results: Fifty-five patients underwent total thyroidectomy and 18 unilateral total lobectomy. Histological examination revealed medullary microcarcinoma in six patients (two women and four men). C-cell hyperplasia was found in 54 patients (74 per cent) and 13 (18 per cent) harboured no C-cell pathology. Calcitonin levels stabilized after lobectomy and became undetectable following thyroidectomy. They normalized during follow-up in a third of patients who did not have surgery. Conclusion: Not all patients with MHCT and sporadic thyroid disease require surgery. Copyright © 2010 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd. [source]


Endoscopists' estimation of size should not determine surveillance of colonic polyps

COLORECTAL DISEASE, Issue 7 2010
S. J. Moug
Abstract Objective, Current British Society of Gastroenterology guidelines use adenomatous polyp size as one of the key factors in determining polyp follow-up. This study aimed to compare polyp size assessment by colonoscopists and pathologists before and after fixation to determine the optimal method for measurement. Method, Thirty-five colorectal polyps were found during pre-arranged colonoscopies in one centre. Polyp size was measured to the nearest 1 mm by three different methods: 1by the endoscopist at colonoscopy; 2by the pathologist fresh, following removal; 3by the pathologist fixed, following fixation. The endoscopist and the pathologist were blinded to each other's measurements. Results, Seventeen men, eighteen women with mean age of 66.2 years (SD: 9.4, range: 38.7,85.5) underwent polypectomy/s with all polyps removed intact. Polypectomies were performed by consultants (43%), nurse specialists (34%) and specialist registrars (23%). The median size (mm) of polyps measured were endoscopically, 6.5 (2,25 mm); fresh specimen 7.0 (4,28 mm) and fixed 7.0 (4,28 mm). Endoscopic measurements were significantly lower than that of fresh and fixed sizes (P < 0.001 and P = 0.003 respectively), with poor correlation [correlation of variance (CV): 21.0% and intraclass correlation coefficient (ICCC): 0.841 for endoscopic and fresh measurements; CV: 21.1% and ICCC: 0.838 for endoscopic and fixed measurements]. There was no statistical difference between fresh and fixed specimen measurements (P > 0.05; CV: 4.2%, ICCC: 0.974). In three patients, the endoscopic measurement was < 1 cm in polyps that were found to be , 1 cm on pathological measurement. Conclusions, Endoscopists consistently underestimated polyp size. Fixation had no effect on polyp size. Pathologists' measurement of polyp size on fixed specimens should determine the need for further colonoscopic follow-up. [source]


Neoadjuvant chemo-radiotherapy and rectal cancer: can the UK watch and wait with Brazil?

COLORECTAL DISEASE, Issue 1 2010
S. M. Nyasavajjala
Abstract Objecive, It has recently been reported that up to one-third of patients with nonmetastatic distal rectal cancer managed with neoadjuvant chemoradiation therapy (CRT) had a complete clinical response (cCR) to treatment. In the selected cases, this has been used as the sole treatment. The aim of this study was to determine the frequency of complete pathological response for patients receiving CRT in one centre in the UK. Method, Patients receiving 6 weeks of neoadjuvant CRT were identified using the two cancer audit databases in two different tertiary hospitals from January 2002 to November 2007. Pathology was reviewed and the histopathological response of the resected specimen to CRT was evaluated using the Mandard classification (1 = complete response, 5 = no response) Results, One hundred and thirty-two consecutive patients [median age 61 (range 44,86) years, 90 men] with nonmetastatic locally advanced rectal cancer received neoadjuvant chemo radiotherapy between 2002 and 2007 followed by resection of the tumour. Data were available from 129 patients. Mandard classification Number of patients 1 13 2 14 3 31 4 47 5 24 Conclusion, Only 13 out of 132 (10%) of patients had a complete pathological response. This is one-third of the cCR previously reported. Nonsurgical therapy for rectal cancer using the Habr-Gama treatment algorithm may only be effective in a very small proportion of patients with rectal cancer in the UK and nonoperative treatment would not be recommended.
