RESUMEN

Dipyridamole intoxication is rare and few reports exist amongst the current literature. A case of dipyridamole and paracetamol overdose is described in a previously healthy 58-year-old woman, which resulted in multi-organ failure requiring dialysis, inotropic support, ventilation and extensive surgical intervention for small bowel ischaemia. This case highlights the dangers of an unusually large overdose of a commonly prescribed drug, and reviews current knowledge of dipyridamole intoxication.

RESUMEN

BACKGROUND: Tumour necrosis is a marker of poor prognosis in some tumours but the mechanism is unclear. This study examined the prognostic value of tumour necrosis and host inflammatory responses in colorectal cancer. METHODS: This was a retrospective study of patients undergoing potentially curative resection of colorectal cancer at a single surgical institution over a 10-year period. Patients who underwent preoperative radiotherapy were excluded. The systemic and local inflammatory responses were assessed using the modified Glasgow Prognostic Score and Klintrup-Makinen criteria respectively. Original tumour sections were retrieved and necrosis graded as absent, focal, moderate or extensive. Associations between necrosis and clinicopathological variables were examined, and multivariable survival analyses carried out. RESULTS: A total of 343 patients were included between 1997 and 2007. Tumour necrosis was graded as absent in 32 (9·3 per cent), focal in 166 (48·4 per cent), moderate in 101 (29·4 per cent) and extensive in 44 (12·8 per cent). There were significant associations between tumour necrosis and anaemia (P = 0·022), white cell count (P = 0·006), systemic inflammatory response (P < 0·001), local inflammatory cell infiltrate (P = 0·004), tumour node metastasis (TNM) stage (P = 0·015) and Petersen Index (P = 0·003). On univariable survival analysis, tumour necrosis was associated with cancer-specific survival (P < 0·001). On multivariable survival analysis, age (hazard ratio (HR) 1·29, 95 per cent confidence interval 1·00 to 1·66), systemic inflammatory response (HR 1·74, 1·27 to 2·39), low-grade local inflammatory cell infiltrate (HR 2·65, 1·52 to 4·63), TNM stage (HR 1·55, 1·02 to 2·35) and high-risk Petersen Index (HR 3·50, 2·21 to 5·55) were associated with reduced cancer-specific survival. CONCLUSION: The impact of tumour necrosis on colorectal cancer survival may be due to close associations with the host systemic and local inflammatory responses.

RESUMEN

AIM: It is recognised that colorectal cancer may arise from different genomic instability pathways. There is evidence to suggest that colon and rectal cancers exhibit different clinicopathological features. We examined the relationship between tumour site, clinicopathological characteristics and cancer-specific survival in patients undergoing potentially curative resection for colorectal cancer. METHOD: Four hundred and eleven patients who underwent surgery. Clinicopathological data including components of the Peterson index, Klintrup scores, haemoglobin and the modified Glasgow Prognostic Score (mGPS) were studied. RESULTS: There were 134 (33%) right sided, 125 (30%) left sided and 152 (37%) rectal tumours. Emergency presentation (P < 0.001), anaemia (P < 0.001), higher mGPS (P < 0.001), advanced T stage (P < 0.001), poor differentiation (P < 0.001) and older age (P < 0.05) were more commonly observed in right sided cancer. The mean follow-up was 94 months (minimum 36 months) and 114 patients died of cancer. There was no difference between tumour site and survival (P = 0.427). On multivariate analysis older age (P = 0.015), lymph node ratio (P < 0.001), mGPS (P = 0.028), Peterson Index (P < 0.001) and Klintrup score (P = 0.008) were independently related to cancer-specific survival. Klintrup score was only associated with poor cancer-specific survival in rectal cancer (P = 0.009). CONCLUSION: The study suggests that colorectal cancer is a group of heterogeneous tumours with different clinicopathological features. Despite this, there was no difference between tumour site and survival. The prognostic role of clinicopathological factors in tumours arising from different genomic instability pathways requires further study.

RESUMEN

AIMS: The incidence of anal squamous cell cancer (SCCA) is rising. Although chemoradiotherapy (CRT) provides a chance of cure, a proportion of patients have an incomplete response or develop recurrence. This study assessed the value of inflammation-based prognostic indicators, including the modified Glasgow Prognostic Score (mGPS) and neutrophil:lymphocyte ratio (NLR), in patients with SCCA treated by CRT with curative intent. MATERIAL AND METHODS: Patients with histologically confirmed SCCA were identified from pathology records. Medical records were retrospectively reviewed and clinical, pathological and treatment characteristics were abstracted. The mGPS (0 = normal C-reactive protein [CRP] and albumin, 1 = CRP >10 mg/l and 2 = CRP >10 mg/l and albumin <35 mg/l) and NLR were calculated from routine blood tests obtained prior to CRT. RESULTS: In total, 118 patients underwent CRT for SCCA between December 2007 and February 2018. Of these, 99 patients had appropriate pretreatment blood results available. Systemic inflammation as indicated by NLR >3 and mGPS >0 was present in 41% and 39% of patients, respectively. Most patients had T2 or larger tumours (n = 85, 86%) without nodal involvement (n = 64, 65%). An elevated mGPS was associated with more advanced T-stage (56% versus 35%, P = 0.036). NLR >5 was associated with nodal positivity (56% versus 31%, P = 0.047). On multivariate analysis, more advanced T-stage (odds ratio 7.49, 95% confidence interval 1.51-37.20, P = 0.014) and a raised mGPS (odds ratio 5.13, 95% confidence interval 1.25-21.14, P = 0.024) were independently related to incomplete CRT response. An elevated mGPS was prognostic of inferior survival (hazard ratio 3.09, 95% confidence interval 1.47-6.50, P = 0.003) and cancer-specific survival (hazard ratio 4.32, 95% confidence interval 1.54-12.15, P = 0.006), independent of TNM stage. CONCLUSION: Systemic inflammation, as measured by the mGPS, is associated with an incomplete CRT response and is independently prognostic of inferior survival in patients with SCCA. The mGPS may offer a simple marker of inferior outcome that could be used to identify high-risk patients.

RESUMEN

BACKGROUND: It is increasingly recognised that host-related factors may be important in determining cancer outcome. The aim was to examine the relationship between patient physiology, the systemic inflammatory response and survival after colorectal cancer resection. METHODS: Patients undergoing potentially curative resection of colorectal cancer were identified from a prospectively maintained database. Patient physiology was assessed using the physiological and operative severity score for the enumeration of mortality and morbidity (POSSUM) criteria. The systemic inflammatory response was assessed using the modified Glasgow Prognostic Score (mGPS). Multivariate 5-year survival analysis was carried out with calculation of hazard ratios (HR). RESULTS: A total of 320 patients were included. During follow-up (median 74 months), there were 136 deaths: 83 colorectal cancer related and 53 non-cancer related. Independent predictors of cancer-specific survival were age (HR: 1.46, P<0.01), Dukes stage (HR: 2.39, P<0.001), mGPS (HR: 1.78, P<0.001) and POSSUM physiology score (HR: 1.38, P=0.02). Predictors of overall survival were age (HR: 1.64, P<0.001), smoking (HR: 1.52, P=0.02), Dukes stage (HR: 1.64, P<0.001), mGPS (HR: 1.60, P<0.001) and POSSUM physiology score (HR: 1.27, P=0.03). A relationship between mGPS and POSSUM physiology score was also established (P<0.006). CONCLUSION: The POSSUM physiology score and the systemic inflammatory response are strongly associated and both are independent predictors of cancer specific and overall survival in patients undergoing potentially curative resection of colorectal cancer.

RESUMEN

BACKGROUNDS AND AIMS: Long term central venous access for Home Parenteral Nutrition (HPN) is associated with catheter related complications. The most studied and well known of these is Catheter Related Blood Stream Infection (CRBSI). This paper looks at other venous access complications, including blocked and damaged catheters, catheter related thrombosis and CRBSI. This paper will also present treatment outcomes for each of these complications. This paper will also examine if there are any correlating patient or catheter related factors that can help predict future catheter related complications. By demonstrating the treatment outcomes for each line complication, it is hoped this will contribute to the literature that could be used for standard setting in complications related to long term central venous access. METHODS: HPN data were analysed from the Greater Glasgow and Clyde (GGC) Home Parenteral Nutrition Database (HPN) which is a comprehensive, prospectively maintained electronic record of all HPN patients treated in GGC. The time period of data collection was 1998-2017. Descriptive statistics were used to report data frequency, age, and catheter days' distributions. Data were not normally distributed and so non-parametric tests were used. Spearman's Rho correlation was used to measure correlation between two numeric groups. Catheter complications were reported as a rate in count data, meaning that more than one event could be recorded per patient, with 1000 catheter days as the person-time denominator. Poisson means test and Fisher exact tests were used to compare different rates, as complications were treated as count data increasing over variable total time periods. P < 0.05 with 95% confidence interval (CI) was considered significant in all tests. Comparisons between binary data sets used two sample t-tests to compare the groups. RESULTS: From 169 patients, 101 (59.8%) were female and 68 (40.2%) were male. The age when first starting HPN ranged from 16 to 79 years old with a median of 56 years. Total catheter days was 173,151 derived from 408 catheter insertions on 169 patients. 282 complications occurred in 85 patients over the study period. An overall catheter complication rate of 1.62/1000 days was found. 84 patients did not experience a single complication. There were 171 proven catheter infections in 66 patients over the study period. Infection rate from the entire period of report was 1.35 infections/1000 catheter days. This decreased over time. Infection was found to be correlated with length of time on HPN, catheter location, catheter diameter and use of Taurolock-Hep100. Thrombosis (n = 16) was associated with total time on HPN (r2 = 0.187, P < 0.05) and the number of infections (r2 = 0.207, P < 0.05). Damage was strongly associated with increasing time on HPN with (r2 of 0.494 and P < 0.005). Blockage was not associated with any patient or catheter factors. Overall catheter salvage rate for CRBSI by antibiotic treatment was 61.87%. Success varied according to organism cultured. Catheter salvage was less successful in other complications and overall catheter salvage rate was 41,115 catheters were salvaged from 282 complications. CONCLUSIONS: This study has provided a baseline for rates of less common venous access complications in HPN and their management. Catheter salvage is possible after at least 41% of complications. It is likely that experience is helpful whether that of individual patient, the team or a clinical network. Our results support the use of smaller central venous catheters, in upper body veins, and the use of Taurolock-Hep100 in patients who have recurrent infections.

RESUMEN

The presence of systemic inflammation before surgery, as evidenced by the glasgow prognostic score (mGPS), predicts poor long-term survival in colorectal cancer. The aim was to examine the relationship between the preoperative mGPS and the development of postoperative complications in patients undergoing potentially curative resection for colorectal cancer. Patients (n=455) who underwent potentially curative resections between 2003 and 2007 were assessed consecutively, and details were recorded in a database. The majority of patients presented for elective surgery (85%) were over the age of 65 years (70%), were male (58%), were deprived (53%), and had TNM stage I/II disease (61%), had preoperative haemoglobin (56%), white cell count (87%) and mGPS 0 (58%) in the normal range. After surgery, 86 (19%) patients developed a postoperative complication; 70 (81%) of which were infectious complications. On multivariate analysis, peritoneal soiling (P<0.01), elevated preoperative white cell count (P<0.05) and mGPS (P<0.01) were independently associated with increased risk of developing a postoperative infection. In elective patients, only the mGPS (OR=1.75, 95% CI=1.17-2.63, P=0.007) was significantly associated with increased risk of developing a postoperative infection. Preoperative elevated mGPS predicts increased postoperative infectious complications in patients undergoing potentially curative resection for colorectal cancer.

RESUMEN

After resection, it is important to identify colon cancer patients, who are at a high risk of recurrence and who may benefit from adjuvant treatment. The Petersen Index (PI), a prognostic model based on pathological criteria is validated in Dukes' B and C disease. Similarly, the modified Glasgow Prognostic Score (mGPS) based on biochemical criteria has also been validated. This study compares both the scores in patients undergoing curative resection of colon cancer. A total of 244 patients underwent elective resection between 1997 and 2005. The PI was constructed from pathological reports; the mGPS was measured pre-operatively. The median follow-up was 67 months (minimum 36 months) during which 109 patients died; 68 of them from cancer. On multivariate analysis of age, Dukes' stage, PI and mGPS, age (hazard ratio, HR, 1.74, P=0.001), Dukes' stage (HR, 3.63, P<0.001), PI (HR, 2.05, P=0.010) and mGPS (HR, 2.34, P<0.001) were associated independently with cancer-specific survival. Three-year cancer-specific survival rates for Dukes' B patients with the low-risk PI were 98, 92 and 82% for the mGPS of 0, 1 and 2, respectively (P<0.05). The high-risk PI population is small, in particular for Dukes' B disease (9%). The mGPS further stratifies those patients classified as low risk by the PI. Combining both the scoring systems could identify patients who have undergone curative surgery but are at high-risk of cancer-related death, therefore guiding management and trial stratification.

RESUMEN

OBJECTIVE: Ileal pouch-anal anastomosis (IPAA) is the operation of choice for patients with ulcerative colitis. Free radical activity and the status of lipid soluble antioxidant vitamins have not been previously assessed in patients with IPAA. The aim of the present study was to measure the plasma concentrations of lipophyllic antioxidants and free radical activity in IPAA patients and compare them with normal subjects. METHOD: Forty-eight IPAA patients and 50 healthy controls were studied. A dietary assessment of vitamin E (alpha-tocopherol) and carotene was undertaken and plasma antioxidant status was assessed. Plasma malondialdehyde (MDA) was measured to assess the extent of free radical damage. In IPAA patients, association between the degree of inflammation in the pouch mucosa and the plasma concentration of lipophyllic antioxidants and extent of free radical activity was investigated. RESULTS: The dietary intake of carotene was similar in both groups. Intake of vitamin E was significantly lower in patients than controls (P = 0.01). In the IPAA group plasma concentrations of alpha-carotene, beta-carotene and lycopene were significantly lower (P < 0.001) and alpha-tocopherol:cholesterol ratio significantly higher (P < 0.001). Free radical damage was significantly greater in patients than controls (P < 0.01). There were no significant correlations between the degree of inflammation in the pouch and plasma concentrations of MDA, carotenoids, alpha-tocopherol:cholesterol ratio or intake of vitamins. CONCLUSION: Compared with normal subjects, patients with IPAA have significantly lower plasma concentrations of lipophyllic antioxidants alpha-carotene, beta-carotene and lycopene and higher free radical activity suggesting increased oxidative stress. These differences do not appear to be related to diet and do not correlate with histological severity of pouch inflammation.

RESUMEN

BACKGROUND: The aim of the present study was to examine the relationship between Ki-67, C-reactive protein and cancer-specific survival in patients undergoing resection for colorectal cancer. METHOD: One hundred and forty-seven patients undergoing potentially curative resection for colorectal cancer had preoperative C-reactive protein concentrations and tumour Ki-67 labelling index measured. RESULTS: On univariate analysis, age (P < 0.001), Dukes stage (P < 0.001), C-reactive protein (P < 0.001) and expression of Ki-67 (< 0.01) were associated with poorer cancer-specific survival. Ki-67 labelling index and C-reactive protein were correlated (r(s) = 0.172, P = 0.037). On multivariate analysis, age (HR 1.96, 95% CI 1.26-3.04, P = 0.003), Dukes stage (HR 4.38, 95% CI 2.11-9.09, P < 0.001) and C-reactive protein (HR 4.09, 95% CI 2.04-8.24, P < 0.001) retained significance. CONCLUSION: Increased tumour proliferation is associated with a systemic inflammatory response and poor cancer-specific survival in patients undergoing potentially curative surgery for colorectal cancer.

RESUMEN

Malnutrition remains a common problem in surgical patients and is associated with significant morbidity and mortality. It is imperative that all surgical patients undergo nutritional screening on admission to highlight malnourished or at risk patients and implement a nutritional plan. Nutrition can be delivered by oral supplements, enteral or parenteral feeding, the route depending on an individual's requirements and surgical condition. Enteral feeding has largely been regarded as superior to parenteral feeding, as it is cheaper, safer and "more physiological" but studies show this is not always the case. This article reviews the basics of surgical nutrition and assesses the evidence supporting enteral versus parenteral nutrition.

RESUMEN

OBJECTIVE: The aim of the study was to compare the Glasgow Nutritional Screening Tool with the Malnutrition Universal Screening Tool (MUST) recently recommended for use by the British Association for Parenteral and Enteral Nutrition. DESIGN: Comparison-validation study. SETTING: Four adult acute hospitals in Glasgow, UK. SUBJECTS: All 242 in-patients from a variety of specialties. METHODS: Two investigators independently interviewed 202 in-patients for the comparison-validation study. Each used a single tool with each patient, using each tool in turn. Investigators were not aware of each other's assessments. Forty other patients were interviewed by both raters separately using the local tool to evaluate inter-rater reliability. RESULTS: When compared with MUST as a 'gold standard', the local tool had a sensitivity of 95.3% and a specificity of 64.9%, with moderate agreement between the two tools using kappa test (kappa=0.57). Agreement between the raters was substantial (kappa=0.69) with 85% of patients classified the same by both raters. CONCLUSION: The Glasgow Nutritional Screening Tool is a valid and reliable tool that can be used on admission for nutritional screening.

RESUMEN

Magnetic resonance (MR) imaging may contribute to staging rectal cancer and inform the decision regarding administration of pre-operative radiotherapy. The accuracy of MR has been debated. The aim of the present study was to determine the accuracy of thin section T2-weighted MR images in rectal cancer patients. MR results were compared with histological assessment of resection specimens. Over a 2-year period, 42 patients were studied. Histological staging was pT2 n = 13, pT3 n = 25 and pT4 n = 4. MR diagnostic accuracy was 74%. MR sensitivity and specificity was 62% and 79% for pT2 lesions, 84% and 59% for pT3 lesions and 50% and 76% for pT4 lesions. Estimation of tumour penetration by thin section MR imaging of rectal cancers using pelvic phased-array coil has moderate diagnostic accuracy. The limitations of MR should be acknowledged when selecting rectal cancer patients for pre-operative radiotherapy.

RESUMEN

BACKGROUND: The complications of central venous line insertion have been highlighted by the recent NICE report advising that ultrasound guidance should be used for central line insertion. METHODS: We report a prospective audit of the complications of subclavian vein central venous line insertion for parenteral nutrition over a five-year period when ultrasound guidance was not used. RESULTS: In total, 201 lines were inserted for parenteral nutrition into a subclavian vein. A single consultant surgeon inserted 120 of the lines and year five or six surgical registrars performed the other line insertions. Five pneumothoraces occurred in four patients who had subclavian lines inserted and a chest drain was required in three cases. Four line tips were found to be going upwards rather than into the superior vena cava. Misplacement was more common with right subclavian insertion. Inability to site the line at that attempt was associated with previous line insertion in four of six patients. CONCLUSION: A low complication rate can be achieved for central line insertion for parenteral nutrition. It is likely that this is due to the small number of experienced operators.

RESUMEN

Nephrogenic Diabetes Insipidus (NDI) is characterised by the inability of the kidneys to concentrate urine in response to arginine vasopressin (AVP). Such patients typically experience polyuria and polydipsia because of this inability to autoregulate their water balance. This provides a perioperative challenge that could lead to a life-threatening situation. This article documents a patient with NDI who underwent an elective bowel re-anastomosis. Two peak serum sodium values were attained. The first when the patient was retaining sodium due to an inappropriate fluid regimen and the second due to hypovolaemia.

RESUMEN

The anti-secretory effects and pharmacokinetics of omeprazole were investigated in ten patients with chronic liver disease. Plasma omeprazole concentrations were measured after a 10-mg intravenous dose of omeprazole and on the first and seventh days of a 7-day course of 10 mg oral omeprazole daily. Pentagastrin tests were performed on the day before oral omeprazole was commenced and 24 h after the last oral dose. The pre-treatment basal and peak gastric acid outputs were low (mean rates of 1.44 mmol/h and 9.26 mmol/h, respectively) and following 7 days of oral 10 mg omeprazole daily, were lowered by 95% and 90% respectively. Following 10 mg intravenous omeprazole, plasma clearance was reduced, and plasma half-life and area under the concentration curve were increased, in comparison with previous studies in healthy subjects. The plasma concentration curves for oral and intravenous doses were very similar. After both the first and seventh oral doses, maximum plasma concentration and area under the curve were higher than in healthy subjects. No accumulation of omeprazole was demonstrated. The pharmacokinetics of omeprazole in chronic liver disease could be influenced by low gastric acidity, poor liver function and/or portasystemic shunting. A dose of 10 mg omeprazole daily has been shown to be an effective anti-secretory agent in chronic liver disease.

RESUMEN

Current interest in the pharmacological manipulation of portal pressure centres on the long-acting somatostatin analogue SMS 201-995. Nine haemodynamically stable cirrhotic patients who had previously bled from oesophageal varices had wedged and free hepatic venous pressures and cardiac index measured, using a Swan-Ganz catheter, before and at 60, 120 and 180 min after beginning a 60-min infusion of 25 microgram/h of SMS 201-995. Seven clinically similar patients had the same measurements performed without SMS 201-995. In all patients cardiac index was found to decrease and systemic vascular resistance increase at 60 min, although heart rates and arterial blood pressures were unchanged. The group given SMS 201-995 was significantly different from the control group in sustaining a fall in wedged hepatic venous pressure and trans-hepatic venous gradient at 60 min. SMS 201-995 causes a fall in portal pressure without a significant systemic haemodynamic effect.

RESUMEN

We assessed the prevalence, methods for recognition and clinical management of malnutrition in acute admissions in a large academic inner-city hospital. Of a total of 337 patients, it was possible to measure both height and weight in 219 patients (65% of admissions). As an alternative for bed-bound patients, mid-upper arm circumference was not very reliable in predicting BMI (sensitivity 98%; specificity 65%), and waist circumference even less so. Of these, 13% were malnourished (body mass index BMI <18.5 kg/m(2) or BMI 18.5-20 kg/m(2) with reported weight loss >3 kg in the last 3 months). Six patients (31% of those with BMI <18.5 kg/m(2)) and one with BMI 18.5-20 kg/m(2) were recognized as suffering from malnutrition and referred to the dietitian. Review of case records could not establish if the diagnosis was missed in the remainder, or if a conscious decision was taken not to manage malnutrition actively. Malnutrition in acute hospital admissions goes apparently unrecognized and unmanaged in 70% of cases. Since there are serious consequences, and effective simple treatment is readily available, increased awareness is required, with routine assessment of nutritional status in all patients.

RESUMEN

BACKGROUND: The last two decades have seen changes in the prevalence, histologic type, and management algorithms for patients with esophageal cancer. The purpose of this study was to evaluate the presentation, stage distribution, and treatment of patients with esophageal cancer using the National Cancer Database of the American College of Surgeons. STUDY DESIGN: Consecutively accessed patients (n = 5,044) with esophageal cancer from 828 hospitals during 1994 were evaluated in 1997 for case mix, diagnostic tests, and treatment modalities. RESULTS: The mean age of patients was 67.3 years with a male to female ratio of 3:1; non-Hispanic Caucasians made up most patients. Only 16.6% reported no tobacco use. Dysphagia (74%), weight loss (57.3%), gastrointestinal reflux (20.5%), odynophagia (16.6%), and dyspnea (12.1%) were the most common symptoms. Approximately 50% of patients had the tumor in the lower third of the esophagus. Of all patients, 51.6% had squamous cell histology and 41.9% had adenocarcinoma. Barrett's esophagus occurred in 777 patients, or 39% of those with adenocarcinoma. Of those patients that underwent surgery initially, pathology revealed stage I (13.3%), II (34.7%), III (35.7%), and IV (12.3%) disease. For patients with various stages of squamous cell cancer, radiation therapy plus chemotherapy were the most common treatment modalities (39.5%) compared with surgery plus adjuvant therapy (13.2%). For patients with adenocarcinoma, surgery plus adjuvant therapy were the most common treatment methods. Disease-specific overall survival at 1 year was 43%, ranging from 70% to 18% from stages I to IV. CONCLUSIONS: Cancer of the esophagus shows an increasing occurrence of adenocarcinoma in the lower third of the esophagus and is frequently associated with Barrett's esophagus. Choice of treatment was influenced by tumor histology and tumor site. Multimodality (neoadjuvant) therapy was the most common treatment method for patients with esophageal adenocarcinoma. The use of multimodality treatment did not appear to increase postoperative morbidity.

RESUMEN

The purpose of home parenteral nutrition (HPN) is to allow patients with intestinal failure a reasonable quality of life and to facilitate independence from hospital. A managed clinical network (MCN) has been established for the organisation of HPN. This multi-professional group works towards optimal patient management by adoption of nationally agreed, evidence standards and protocols, to allow equity of access to quality care. A coordinator has identified patients and practice. A MCN exists to ensure that quality care can be delivered near to the patient's home. An audit of the organisation of HPN has been completed. The aims of this study were to identify the numbers of patients receiving this treatment and to assess management practices. Data was collected from 16 centres between July 2000 and August 2001. This paper discusses the practicalities of setting up the network and presents data from the first full year of audit. This will act as the baseline for continuous audit and a basis for revision of documentation.
