Since 2002, the postal audit in dental radiography has been supplementing standard quality control (QC) tools for dental intraoral X-ray machines. An aim of the audit is to check basic X-ray machine parameters (field size, exposure reproducibility), and a quality of the whole process of diagnostic imaging (entrance surface air-kerma measurement, a check of film processing and an image quality evaluation). The standard QC tests, performed by private companies, check mainly the X-ray unit. Conversely, the audit gives better information about the patient examination practices. During the period of January 2002 to May 2004 approximately 4000 audits were performed. The results confirmed that main problems in dental radiography are due to incorrect film processing, non-optimised setting of the exposure parameters and use of obsolete X-ray machines. Only approximately 30% of performed audits were satisfactory with respect to all checked parameters.

According to the Standards of the World Marrow Donor Association (WMDA), unrelated stem cell donor registries and donor centers are responsible for compliance of their collection and apheresis centers with these Standards. To ensure high stem cell product quality and high standards for safety and satisfaction of voluntary unrelated stem cell donors, we here present guidelines for audits of collection and apheresis centers that can be used by new and established donor registries, as well as by collection centers in preparation of audits. We define the general requirements and recommendations for collaboration with the collection and apheresis centers and define critical procedures for the collection of the stem cell product, such as information session, medical assessment, product collection, quality controls, product handover for transportation, and donor follow-up. The specific guidelines are accompanied by detailed checklists and forms that can be found in Supplementary Information and may be used during an initial or follow-up on-site or paper-based audit.

OBJECTIVE: An audit was performed to assess the number, indications and complications of peripartum hysterectomy at the departments of obstetrics/gynecology in Slovakia in 2007. DESIGN: Observational descriptive study. SETTING: Department of Obstetrics and Gynecology, Faculty Hospital Nitra and Constantine the Philosopher University Nitra. METHOD: An official questionnaire of Slovak Society of Obstetrics and Gynecology was sent to all 63 departments of obstetrics/gynecology to find the number of peripartum hysterectomy performed in the year 2007. Differences between intrapartum and postpartum cases were compared. RESULTS: 44 from 63 institutions responded to the survey (response rate 69.8%). There were 38,485 deliveries and 24 cases of peripartum hysterectomies. The incidence of peripartum hysterectomy was 0.62/1000 deliveries, 1 case occurred in 1604 deliveries. 16 (66.7%) patients had a total abdominal hysterectomy with the remaining 8 (33.3%) having a sub-total hysterectomy. All operations were emergent. 18 procedures were performed during delivery and 6 in the postpartum period. Hypogastric artery ligation before hysterectomy were performed on 2 patients in the postpartum group. 20 of 24 (83.3%) patients delivered by cesarean section, three (12.5%) by spontaneous vaginal delivery and one (4.2%) with vaccumextraction. The indications for emergency peripartum hysterectomy were: placenta praevia 6 cases (25%), placental abruption with disseminated intravascular coagulation 6 (25%), placenta accreta 3 (12.5%), uterine atony 3 (12.5%), uterine rupture 3 (12.5%) and retroperitoneal haematoma 3 (12.5%). The youngest patient was 15 year-old, the oldest one was 39. After hysterectomy 10 (41.7%) women were admitted to the intensive care unit. There was no maternal mortality, but five newborns died due to perinatal asphyxia. There were more blood transfusions in the group of postpartum hysterectomies in comparison with intrapartum cases (4.0 +/- 1.3 transfusion units vs 9.1 +/- 3.5, p < 0.05), as well as the longer hospital stay (10.3 +/- s4.2 days vs. 19.1 +/- 5.3, p < 0.05). CONCLUSIONS: Peripartal hysterectomy is a dramatic but a life saving procedure. It is usually associated with significant maternal and fetal morbidity and mortality. Every obstetric service should have access to a surgical team capable of performing emergency peripartal hysterectomy.

BACKGROUND: The aim of this retrospective study was to compare the failure rates and the frequency of anaesthesia-related complications of two different methods of regional anaesthesia used for carotid endarterectomy--cervical epidural (CE) anaesthesia and cervical plexus block (CPB). METHODS: The study included 1828 carotid endarterectomies performed in 1455 patients between 1996 and 2006. A combination of deep and superficial CPB was used for 1166 procedures, whereas in 662 cases surgery was performed under CE anaesthesia. RESULTS: The failure rate of CPB was 3% compared with 6.9% for CE anaesthesia (P < 0.0001). The reasons for failure of the anaesthetic techniques were (1) technical failure, (2) insufficient analgesia, (3) non-compliant patients, and (4) anaesthetic complications. The incidence of complications resulting from CE anaesthesia was significantly higher than with CPB; life-threatening complications--2% compared with 0.3% (P < 0.0001); other anaesthesia-related complications 5.7 vs 4.7%. Serious complications included inadvertant injection into the subarachnoid space or vertebral artery. The frequency of shunt insertion, perioperative stroke, and death from any cause was similar in both groups of patients. CONCLUSIONS: Both methods of regional anaesthesia are acceptable for carotid artery surgery. CPB is associated with a significantly lower frequency of anaesthesia-related complications and should therefore be considered the anaesthetic of choice. CE anaesthesia should not be performed except in extenuating circumstances such as variant anatomy or the requirement for more extensive surgery.

BACKGROUND: Inflammatory bowel disease-unclassified (IBD-U) is diagnosed in ∼10% of pediatric and adolescent onset IBD patients. The EUROKIDS registry (2004) initiated by the Porto IBD working group of ESPGHAN prospectively monitors diagnostic workup of newly diagnosed pediatric and adolescent onset IBD patients. We aimed to describe diagnostic workup, phenotype, and change of diagnosis over time in pediatric IBD-U patients. METHODS: Data were collected on children from 52 centers across 20 European countries and Israel, diagnosed with IBD from May 2005 through November 2013. Full endoscopy plus small bowel radiology was considered complete diagnostic workup. Participating centers reporting IBD-U patients were queried in 2014 for follow-up data. RESULTS: IBD-U was the provisional first diagnosis in 265 of 3461 children (7.7%) (91/158 [58%] with pancolitis; 140 [53%] male), diagnosed more frequently under the age of 10 (median age 12.3 years, 89 [34%] under 10 years). Half (48%) had undergone complete diagnostic workup. Lack of small bowel radiology was the prevailing reason for incomplete workup. As a result of reinvestigations (endoscopy in 54%, radiology in 38%) during a median follow-up of 5.7 years (interquartile range, 2.5-7.8), a change in diagnosis from IBD-U to Crohn's disease (12%) or ulcerative colitis (20%) was reported. CONCLUSIONS: Only half of patients reported as IBD-U in EUROKIDS had undergone complete diagnostic workup. Follow-up with reinvestigations resulted in a reduction of IBD-U rate to 5.6%. A diagnosis of IBD-U becomes less likely in case of complete diagnostic workup. Implementation of clear diagnostic criteria will further reduce the rate of IBD-U in the future.

Introduction: Within an International Atomic Energy Agency (IAEA) co-ordinated research project (CRP), a remote end-to-end dosimetric quality audit for intensity modulated radiation therapy (IMRT)/ volumetric arc therapy (VMAT) was developed to verify the radiotherapy chain including imaging, treatment planning and dose delivery. The methodology as well as the results obtained in a multicentre pilot study and national trial runs conducted in close cooperation with dosimetry audit networks (DANs) of IAEA Member States are presented.Material and methods: A solid polystyrene phantom containing a dosimetry insert with an irregular solid water planning target volume (PTV) and organ at risk (OAR) was designed for this audit. The insert can be preloaded with radiochromic film and four thermoluminescent dosimeters (TLDs). For the audit, radiotherapy centres were asked to scan the phantom, contour the structures, create an IMRT/VMAT treatment plan and irradiate the phantom. The dose prescription was to deliver 4 Gy to the PTV in two fractions and to limit the OAR dose to a maximum of 2.8 Gy. The TLD measured doses and film measured dose distributions were compared with the TPS calculations.Results: Sixteen hospitals from 13 countries and 64 hospitals from 6 countries participated in the multicenter pilot study and in the national runs, respectively. The TLD results for the PTV were all within ±5% acceptance limit for the multicentre pilot study, whereas for national runs, 17 participants failed to meet this criterion. All measured doses in the OAR were below the treatment planning constraint. The film analysis identified seven plans in national runs below the 90% passing rate gamma criteria.Conclusion: The results proved that the methodology of the IMRT/VMAT dosimetric end-to-end audit was feasible for its intended purpose, i.e., the phantom design and materials were suitable; the phantom was easy to use and it was robust enough for shipment. Most importantly the audit methodology was capable of identifying suboptimal IMRT/VMAT delivery.

BACKGROUND AND PURPOSE: An audit methodology for verifying the implementation of output factors (OFs) of small fields in treatment planning systems (TPSs) used in radiotherapy was developed and tested through a multinational research group and performed on a national level in five different countries. MATERIALS AND METHODS: Centres participating in this study were asked to provide OFs calculated by their TPSs for 10 × 10 cm2, 6 × 6 cm2, 4 × 4 cm2, 3 × 3 cm2 and 2 × 2 cm2 field sizes using an SSD of 100 cm. The ratio of these calculated OFs to reference OFs was analysed. The action limit was ±3% for the 2 × 2 cm2 field and ±2% for all other fields. RESULTS: OFs for more than 200 different beams were collected in total. On average, the OFs for small fields calculated by TPSs were generally larger than measured reference data. These deviations increased with decreasing field size. On a national level, 30% and 31% of the calculated OFs of the 2 × 2 cm2 field exceeded the action limit of 3% for nominal beam energies of 6 MV and for nominal beam energies higher than 6 MV, respectively. CONCLUSION: Modern TPS beam models generally overestimate the OFs for small fields. The verification of calculated small field OFs is a vital step and should be included when commissioning a TPS. The methodology outlined in this study can be used to identify potential discrepancies in clinical beam models.

BACKGROUND: Both anastomotic leak (AL) and conduit necrosis (CN) after oesophagectomy are associated with high morbidity and mortality. Therefore, the identification of preoperative, modifiable risk factors is desirable. The aim of this study was to generate a risk scoring model for AL and CN after oesophagectomy. METHODS: Patients undergoing curative resection for oesophageal cancer were identified from the international Oesophagogastric Anastomosis Audit (OGAA) from April 2018-December 2018. Definitions for AL and CN were those set out by the Oesophageal Complications Consensus Group. Univariate and multivariate analyses were performed to identify risk factors for both AL and CN. A risk score was then produced for both AL and CN using the derivation set, then internally validated using the validation set. RESULTS: This study included 2247 oesophagectomies across 137 hospitals in 41 countries. The AL rate was 14.2% and CN rate was 2.7%. Preoperative factors that were independent predictors of AL were cardiovascular comorbidity and chronic obstructive pulmonary disease. The risk scoring model showed insufficient predictive ability in internal validation (area under the receiver-operating-characteristic curve [AUROC] = 0.618). Preoperative factors that were independent predictors of CN were: body mass index, Eastern Cooperative Oncology Group performance status, previous myocardial infarction and smoking history. These were converted into a risk-scoring model and internally validated using the validation set with an AUROC of 0.775. CONCLUSION: Despite a large dataset, AL proves difficult to predict using preoperative factors. The risk-scoring model for CN provides an internally validated tool to estimate a patient's risk preoperatively.
