[Patient safety culture for health professionals in primary care : French adaptation of the MOSPSC questionnaire (Medical Office Survey on Patient Safety Culture)]. / Culture de sécurité des professionnels de santé en soins primaires : adaptation en langue française du questionnaire MOSPSC (« Medical Office Survey on Patient Safety Culture ¼).

BACKGROUND: Patient safety culture (PSC) takes into account a number of individual and organizational factors. Evaluation of PSC with the participation of primary health care professionals can be carried out through self-administered surveys such as the AHRQ's Medical Office Survey on Patient Safety Culture (MOSPSC) questionnaire. AIM: To translate the MOSPSC questionnaire into French, while analyzing its psychometric properties. METHODS: The MOSPSC questionnaire was first translated into French, with linguistic analysis included, and then back-translated into English, in accordance with the ISPOR recommendations. Lastly, the French version of the MOSPSC questionnaire was completed by health professionals from 36 outpatient structures. Study of the psychometric properties (test-retest, Cronbach's α, and factor analysis) was conducted based on the professionals' responses. RESULTS: After linguistic analysis, the notion of "team" was translated in the final questionnaire as "structure". This term was used in the pilot survey of 415 professionals. The participation rate was 64.1% (266/415); 51.9% (138/415) were paramedics (mainly nurses and physiotherapists). The Cronbach coefficient α inclusive of all dimensions was 0.94. A "reporting of safety incidents" dimension was added, and the "staff training" dimension was merged with "development and standardization of office processes", bringing to 13 the number of dimensions identified after factor analysis. CONCLUSIONS: Having been adapted and validated, the French version of the questionnaire can be used as a tool for assessment of PSC in France. It should not only facilitate the monitoring of PSC in primary care facilities, but also prove conducive to comparison of PSC evolution in different establishments. Lastly, it Could contribute to national and international research on risk management in primary care.

Assessment of patient safety culture: what tools for medical students?

BACKGROUND: The assessment of patient safety culture refers mainly to surveys exploring the perceptions of health professionals in hospitals. These surveys have less relevance when considering the assessment of the patient safety culture of medical students, especially at university or medical school. They are indeed not fully integrated in care units and constitute a heterogeneous population. This work aimed to find appropriate assessment tools of the patient safety culture of medical students. METHODS: Systematic review of the literature. Surveys related to a care unit were excluded. A typology of the patient safety culture of medical students was built from the included surveys. RESULTS: Eighteen surveys were included. In our typology of patient safety culture of medical students (15 dimensions), the number of dimensions explored by survey (n) ranged from 1 to 12, with 6 "specialized" tools (n ≤ 4) and 12 "global" tools (N ≥ 5). These surveys have explored: knowledge about patient safety, acknowledgment of the inevitability of human error, the lack of skills as the main source of errors, the errors reporting systems, disclosure of medical errors to others health professionals or patients, teamwork and patient involvement to improve safety in care. CONCLUSIONS: We recommend using Wetzel's survey for making an overall assessment of the patient safety culture of medical students at university. In a specific purpose-e.g. to assess an educational program on medical error disclosure-the authors recommend to determine which dimensions of patient safety will be taught, to select the best assessment tool. Learning on patient safety should however be considered beyond the university. International translations of tools are required to create databases allowing comparative studies.

[Primary eccrine porocarcinoma: a clinicopathological study of 50 cases]. / Étude clinique et histopronostique de 50 cas de porocarcinome eccrine.

BACKGROUND: Eccrine porocarcinoma is a rare cutaneous tumor arising from the intra-epidermal portion of eccrine sweat glands, the acrosyringium. Histoprognostic studies in large series are rare. Herein, we report a retrospective study of 50 cases. PATIENTS AND METHODS: Fifty cases of porocarcinoma were retrieved from a histopathological register. Each histopathological sample was evaluated for the following criteria: presence or absence of dermal invasion, pattern of the infiltrative component (pushing or infiltrative), tumor thickness, lymphovascular emboli, perineural invasion and mitotic index. Clinical data and outcome were also retrieved for each patient. RESULTS: Mean patient age was 77 years (range: 43-99 years). The mean duration of progression prior to diagnosis was 4 years and 5 months. The 2 most common skin locations were the head (38%) and lower limbs (20%). The lesions showed no specific distinctive clinical features. Six cases were in situ, and 44 were invasive (23 with limited infiltration and 20 with scattered infiltration). Mean tumor thickness was 4.37 mm (range: 0.5 to 20 mm). Neighboring or remote epidermal involvement was noted in 7 cases. Lymphovascular emboli were observed in 3 cases. No cases of neurotropism were observed. The average mitotic index was 6.5 mitoses/high power (×400) field. A mean follow-up of 24.3 months was available for 48 patients. Local recurrence was noted in 5 patients, 4 of whom died from visceral metastases. These 5 cases showed no distinctive clinical features, a scattered pattern of the invasive component, cuticular cells, significant tumor thickness (mean 12.8 mm, range 9-20 mm), and an elevated mitotic index. Two histopathological criteria were significantly associated with a metastatic outcome: scattered pattern of the dermal invasive component (P=0.04) and significant tumor thickness, above 10mm (P<0.01). CONCLUSION: Porocarcinoma is a tumor without any particular clinical criteria to distinguish it from squamous cell carcinoma. The architecture of the invasive component and tumor thickness constitute 2 important histoprognostic criteria.

Human papillomavirus prevalence, persistence and cervical dysplasia in females with cystic fibrosis.

BACKGROUND: A higher risk of human papillomavirus (HPV)-related cervical intra-epithelial neoplasia (CIN) is suspected among females with cystic fibrosis (CF). METHODS: We conducted a single center prospective cohort study among females attending the Lyon adult CF center. We performed a cervical cytology (Hologic Thinprep®) and HPV testing with genotyping (Clinical Arrays Papillomavirus; Genomica, enabling 35 genotype detection, 20 of which are high-risk (HR-HPV)) at inclusion. We followed all females with positive HPV tests at 6, 12 and 24 months to evaluate HPV persistence, and performed a colposcopy in cases of abnormal cytology. RESULTS: We included eighty-five participants, 18 (21%) of whom were lung-transplanted. The mean age at inclusion was 31.9 (range 18-59) years. The prevalence of HPV (all types) was 31.8%. HR-HPV was found in 25.9% of the whole cohort, 44.4% of transplanted patients, and 20.1% of nontransplanted patients. Genotype-specific HR-HPV persistence at 12 months was 43.5% among transplanted and 34.6% among nontransplanted patients. Overall, 17.6% (15/85) of females had an abnormal cytology: 44.4% (8/18) among transplanted and 10.4% (7/67) among nontransplanted patients. CIN was identified in 12 (14.1%) patients (6 low-grade, 6 high-grade). High-grade CIN developed in 4 nontransplanted patients. CONCLUSION: Transplanted females had high HR-HPV, abnormal cervical cytology and CIN prevalence rates compared to large published cohorts in the general non-CF population. Although HR-HPV prevalence and persistence were globally not significantly different in nontransplanted females compared to the general population, we reported high frequencies of abnormal cytology and CIN. Cervical cancer screening and prevention should be promoted among females with CF.

[ICD-10 adaptation of 15 Agency for Healthcare Research and Quality patient safety indicators]. / Adaptation au codage CIM-10 de 15 indicateurs de la sécurité des patients proposés par l'Agence étasunienne pour la recherche et la qualité des soins de santé (AHRQ).

BACKGROUND: In the United States, the Agency for Healthcare Research and Quality (AHRQ) has developed 20 Patient Safety Indicators (PSIs) to measure the occurrence of hospital adverse events from medico-administrative data coded according to the ninth revision of the international classification of disease (ICD-9-CM). The adaptation of these PSIs to the WHO version of ICD-10 was carried out by an international consortium. METHODS: Two independent teams transcoded ICD-9-CM diagnosis codes proposed by the AHRQ into ICD-10-WHO. Using a Delphi process, experts from six countries evaluated each code independently, stating whether it was "included", "excluded" or "uncertain". During a two-day meeting, the experts then discussed the codes that had not obtained a consensus, and the additional codes proposed. RESULTS: Fifteen PSIs were adapted. Among the 2569 proposed diagnosis codes, 1775 were unanimously adopted straightaway. The 794 remaining codes and 2541 additional codes were discussed. Three documents were prepared: (1) a list of ICD-10-WHO codes for the 15 adapted PSIs; (2) recommendations to the AHRQ for the improvement of the nosological frame and the coding of PSI with ICD-9-CM; (3) recommendations to the WHO to improve ICD-10. CONCLUSIONS: This work allows international comparisons of PSIs among the countries using ICD-10. Nevertheless, these PSIs must still be evaluated further before being broadly used.

[Improvement of maxillofacial bone distraction osteogenesis: future prospects]. / Potentialisation de la distraction ostéogénique maxillofaciale, voies d'avenir.

Distraction osteogenesis is a tissue engineering technique based on Ilizarov's study on long bones. McCarthy transposed it rapidly to facial bones. His results in cranial and maxillofacial surgery are good and reproducible. However, the current protocols are long and the devices used are bulky. Finding new devices and association with other tissue engineering techniques should improve distraction osteogenesis and the patient's comfort.

Dermoscopic features of acral lentiginous melanoma in a large series of 110 cases in a white population.

BACKGROUND: Acral lentiginous melanoma (ALM) is a rare but distinctive subtype of melanoma. The diagnosis is often delayed and misdiagnosis is common, due to frequently unusual clinical presentation and a higher rate of amelanosis than in other melanoma subtypes. OBJECTIVES: We aimed to investigate the dermoscopic features of a large series of ALM in a white-skinned population, in order to emphasize their diagnostic value. METHODS: All recorded dermoscopic photographs of ALM, including nail unit variants, were collected from the files of the University Hospital Department of Dermatology (Lyons, France) and reviewed. RESULTS: In total 110 lesions, including 66 (60%) palmoplantar ALM and 44 (40%) ALM of the nail apparatus, were analysed for dermoscopic characteristics. The mean Breslow thickness was 2.6 mm. In volar skin melanomas, the two most prevalent patterns were irregular diffuse pigmentation (60%) and the parallel-ridge pattern (53%). Minor dermoscopic patterns, commonly noted in benign lesions, were also detected but only focally within the lesions. Among the 44 nail unit lesions, 31 (70%) presented irregular lines with variegations in colours, spacing, width and disruption of parallelism. Two cases of melanonychia striata had a triangular shape. Both corresponded to early ungual ALM. Association with subungual haemorrhage was not uncommon. The study included 37 (34%) amelanotic melanomas. However, dermoscopy enabled detection of microscopic remnants of pigmentation in most cases. The vascular pattern found in almost half of these lesions was polymorphous, with combinations of milky-red areas (95%), linear irregular vessels (49%), dotted vessels (43%) and hairpin vessels (41%). CONCLUSIONS: The presence of a parallel-ridge pattern and/or irregular diffuse pigmentation within the lesion is highly indicative of melanoma on volar skin. An irregular lines pattern is the most prominent dermoscopic feature of pigmented ALM of the nail apparatus. Amelanotic ALM either in volar skin or in nail apparatus is characterized by remnants of pigmentation and a polymorphic vascular pattern.

Multifaceted intervention to decrease the rate of severe postpartum haemorrhage: the PITHAGORE6 cluster-randomised controlled trial.

OBJECTIVE: Decreasing the prevalence of severe postpartum haemorrhages (PPH) is a major obstetrical challenge. These are often considered to be associated with substandard initial care. Strategies to increase the appropriateness of early management of PPH must be assessed. We tested the hypothesis that a multifaceted intervention aimed at increasing the translation into practice of a protocol for early management of PPH, would reduce the incidence of severe PPH. DESIGN: Cluster-randomised trial. POPULATION: 106 maternity units in six French regions. METHODS: Maternity units were randomly assigned to receive the intervention, or to have the protocol passively disseminated. The intervention combined outreach visits to discuss the protocol in each local context, reminders, and peer reviews of severe incidents, and was implemented in each maternity hospital by a team pairing an obstetrician and a midwife. MAIN OUTCOME MEASURES: The primary outcome was the incidence of severe PPH, defined as a composite of one or more of: transfusion, embolisation, surgical procedure, transfer to intensive care, peripartum haemoglobin decrease of 4 g/dl or more, death. The main secondary outcomes were PPH management practices. RESULTS: The mean rate of severe PPH was 1.64% (SD 0.80) in the intervention units and 1.65% (SD 0.96) in control units; difference not significant. Some elements of PPH management were applied more frequently in intervention units-help from senior staff (P = 0.005), or tended to - second-line pharmacological treatment (P = 0.06), timely blood test (P = 0.09). CONCLUSION: This educational intervention did not affect the rate of severe PPH as compared with control units, although it improved some practices.

Quality monitoring in thyroid surgery using the Shewhart control chart.

BACKGROUND: A control chart can help to interpret and reduce sources of variability in patient safety by continuously monitoring indicators. The aim of this study was to monitor the outcome of thyroid surgery using control charts. METHODS: Patients who had thyroid surgery during 2006-2007 were included in the study. Safety was monitored based on postoperative complications of recurrent laryngeal nerve palsy and hypocalcaemia. Indicators were extracted prospectively from the hospital information system and plotted each month on a P-control chart. Performance of the surgical team was also measured retrospectively for 2004-2005 (baseline period) to compare surgical outcomes before and after control chart implementation. Electromyographic monitoring of recurrent laryngeal nerves was not used, nor was calcium or vitamin D given routinely. RESULTS: The outcomes of 1114 thyroid procedures were monitored. Although the proportion of patients with recurrent laryngeal nerve palsy was similar for baseline and monitored periods (6.4 and 7.2 per cent respectively), there was a 35.3 per cent decrease in hypocalcaemia after implementation of control charts (P < 0.001). Complications almost doubled during a period when one surgeon was away and operating room renovations took place. CONCLUSION: Outcome monitoring in thyroid surgery using control charts is useful for identifying potential issues in patient safety.

Impact of guidelines for endoscopy in patients with Barrett's esophagus: a multifaceted interventional study.

OBJECTIVE: To evaluate the impact of a multifaceted interventional program on the compliance of hepatogastroenterologists with guidelines for Barrett's esophagus. DESIGN: In both 2002 and 2005, anonymous postal surveys were sent out, involving eight criteria pertaining to three main areas to assess compliance, to 245 hepatogastroenterologists based in private and public hospitals, and in the community, in a specific region of France. The multifaceted intervention was based on reminders, conferences, postal campaigns and esophageal mapping. Main outcome measures were based on biopsies for diagnosis, surveillance intervals and management of patients with high-grade dysplasia. RESULTS: In 2002 and 2005, survey response rates were 81.6 and 73.9%, respectively. In terms of diagnosis, compliance with the systematic performance of biopsies increased from 26.5 to 59.9% (p<0.01) and, with follow-up, from 41.0 to 52.0%, respectively (p<0.02). Management of high-grade dysplasia increased from 16.0 to 24.3% (p<0.01). Total compliance (with all criteria) was achieved by 5.0% of hepatogastroenterologists in 2002 and by 10.7% in 2005 (p<0.01). CONCLUSION: The present study suggests that a multifaceted interventional program can dramatically improve physician compliance with the guidelines for Barrett's esophagus. For this reason, we recommend that national scientific societies disseminate their guidelines through targeted activity to ensure that they are followed by hepatogastroenterologists.

[Patient awareness and satisfaction of the Aurore perinatal network]. / Connaissance et satisfaction des femmes au sein du réseau de santé périnatal Aurore.

OBJECTIVES: Assess patient awareness, satisfaction and expectations three years after the implementation of the Aurore perinatal network. METHOD AND MATERIALS: Semi-guided interviews with 60 Aurore network perinatal patients, 20 having undergone in-utero transfers (IUT), 20 whose newborns were transferred to the neonate unit (NNT), and 20 post-delivery without IUT or NNT, between September 2007 and January 2007. RESULTS: Fifteen percent of patients were familiar with the Aurore perinatal network (9/60). The concepts of IUT and NNT were not associated with that of the perinatal network. The information provided helped 85 % of the patients to feel more secure (51/60). For 83 % of the patients with mother-child bond was maintained (50/60). In 90 % of cases, the teams included the father in the healthcare provision process (54/60). Patients had expectations on a greater consideration on the emotional aspect during a transfer. CONCLUSION: Few patients knew the perinatal network. They were globally satisified during a transfer, they insisted on the importance of staff empathy and availability.

[Early prenatal interview: implementation of a sheet link "carried" by patient. The Aurore perinatal network experience]. / Entretien prénatal précoce : mise en place d'une fiche de liaison << portée >> par la patiente. A propos de l'expérience du réseau périnatal Aurore.

INTRODUCTION: Early prenatal interview has needed the implementation of a new communication tool between follow-up pregnancy professionals: a link sheet filled and carried by patients. OBJECTIVE: To assess the utilization of link sheet by trained professionals, the contribution of the interview and the patient acceptation of the link sheet. MATERIALS AND METHOD: Descriptive survey from the database of link sheets returned by professionals to Aurore perinatal network and semi-guided interviews with 100 randomized patients. RESULT: One thousand one hundred and nineteen link sheets were sent to Aurore perinatal network by 55 professionals out of 78 trained. For primipare, precocious prenatal interview contribution has concerned health care security (60%) and emotional security (56%). For multipare, this contribution has concerned mainly emotional security (80%). No interviewed patient has refused link sheet principle. CONCLUSION: Link sheet principle, like implemented by Aurore perinatal network, seems pertinent to professionals and patients but it constitutes only one of the elements of network elaboration of personalized care.

[Evaluation of the perinatal network professionals' integration: study about 653 professionals of AURORE network]. / Evaluation de l'intégration des professionnels au sein d'un réseau de périnatalité: enquête auprès de 653 professionnels du réseau AURORE.

OBJECTIVES: Evaluation of the AURORE perinatal network professionals' satisfaction and integration and identification of explanatory factors, three years after implementation. METHOD AND MATERIALS: Transversal study with postal questionnaire sent at 653 AURORE network perinatal professionals. RESULTS: Awareness and participation to network meetings were not associated with the geographic proximity of administrative headquarters (p=0.2) but with consciousness of network website and of network experts identified for each maternity (p<0.001). Patients management was estimated more easy for 92% of professionals. Network impact was evaluated as positive in professional practice (88.2%). Professionals integration were demonstrated by knowledge of network guidelines (94.8%) and their use (96%). CONCLUSION: AURORE perinatal network professionals, three years after implementation, were involved in network maternity. Their participation and interest for this organisation were associated with directs benefits they could get in facilitating their relationship with patients and other health professionals in each day practice.

Upper limb and hand patterns in cerebral palsy: Reliability of two new classifications.

AIM: To evaluate the inter- and intra-rater reliability of two previously developed classifications of upper limb and hand patterns. METHOD: Two hundred and twelve films of patients with CP (118 of UL postures and 94 of hand tasks; median age 14, 3-46 years) were viewed by 18 examiners from 2 different rehabilitation centers, and one expert who had participated in the design of the classifications. They classed upper limb (3 patterns with sub-types) and hand patterns (2 patterns with subtypes) twice, at 2 months' interval. Inter- and intra-rater reliability were analysed. RESULTS: Intra-rater and inter-rater reliability were very high for upper limb and hand patterns (0.87 < k < 0.92), and high for the subtypes (0.58 < k < 0.68). Examiners stated that both classifications were useful and feasible in clinical practice. INTERPRETATION: Despite the single, short training session on use of the classifications, agreement between the examiners and the expert examiner was good to high, confirming that these classifications are easy to use and reliable. The classifications proposed here provide homogenous terminology for use in both clinical practice and research, to describe, evaluate and follow-up changes in upper limb and hand patterns in patients with cerebral palsy, particularly those with dyskinesia.

[Evaluation of clinical practices: methods of data collection and information sources?]. / L'évaluation des pratiques cliniques: quels modes de recueil des données et à partir de quelles sources d'information?

OBJECTIVE: The aim of our study is to present the methods used to observe clinical practices, to evaluate their advantages and limits, and to specify the context in which they are preformed. METHODS: We conducted a bibliographical search on MEDLINE using key words, completed by an offline search. We selected articles published in French or English between 1985 and 2003. RESULTS: Thirty articles, of which 3 were reviews, as well as an additional 5 reports and 9 books, were selected. We distinguished direct or objective approaches to clinical practices as well as indirect or declarative approaches. We also noted whether the approach was individual with data collected from individual practitioners, or collective, with data coming from databases. Most methods of collecting data used medical records, often in the context of internal or external clinical audits or peer reviews. The other sources of data were self-administered questionnaires, written case simulations and simulated patients. Data was also extracted from previously existing databases: claims databases, registries and ad hoc databases. CONCLUSION: An objective individual approach insures the highest quality of information, but possible high costs can limit the use of this approach. It is necessary to continue researching the best means of collecting data on clinical practices, because of the obligation of each practitioner to evaluate individual clinical practices.

Management of drooling in children with cerebral palsy: A French survey.

AIM: To characterise children with cerebral palsy (CP) and pathological drooling in France, and to describe care pathways, assessment and treatment. METHOD: A transversal, observational, descriptive survey of the practices and opinions of 400 health professionals potentially involved in the care of children with CP, was carried out nationally across France in 2013. RESULTS: The response rate was 36%. Seventy-five questionnaires were returned and analysed (52%). A small proportion of children were specifically treated for drooling (<25%). Assessments were carried out in 75% of cases and 91% of professionals prescribed treatments. Use of assessment tools varied widely. The most common treatment was oro-facial rehabilitation (95% of professionals), followed by anticholinergic drugs (Scopolamine(®)) (94%) botulinum toxin injections (BT) (66%) and surgery (34%). Scopolamine was considered to be less effective than BT and to have more side effects. CONCLUSION: The rate of pathological drooling in children with CP is likely underestimated and under treated in France. There is a lack of knowledge regarding assessment tools. Aside from rehabilitation, current practice is to prescribe medication as the first-line treatment, however professionals consider that BT is more effective and has less side effects.

[Compliance with a protocol of prevention of neonatal group B streptococcal sepsis in the Aurore perinatal network]. / Application d'un protocole de prévention de l'infection materno-foetale à streptocoque B hémolytique au sein du réseau périnatal Aurore.

OBJECTIVE: Our purpose was to measure the compliance with the network hospitals protocol for preventing neonatal group B streptococcal sepsis. MATERIALS AND METHOD: All vaginal deliveries during a one-week period in 37 maternities of the perinatal network were reviewed retrospectively. RESULTS: A total of 752 records were reviewed. Compliance with the protocol regarding the time of culture was 91.1%. Overall, prevalence of group B streptococcal carriage was 14.2%. Among patients eligible for intrapartum antibiotics, 46.4% received adequate prophylaxis. Considering the length of labor, one out of two patients could have received intrapartum adequate antibiotics. Regarding newborns, 86.1% received adequate medical surveillance. There was no confirmed case of group B streptococcal sepsis during the week of study. CONCLUSION: All the maternities of network Aurore accepted and adopted evaluation principle. Some elements of protocol could be better applied, in particular delivering adequate intrapartum antibiotic prophylaxis.

Implementation of a computerized system in pediatric wards to improve nutritional care: a cluster randomized trial.

BACKGROUND/OBJECTIVES: Malnutrition occurs frequently in hospitalized children. We aimed to assess whether a computerized system could lead to improved clinical practices in malnourished children. SUBJECTS/METHODS: Healthcare workers (242) from six departments in a pediatric university hospital participated in a cluster randomized trial, studying 1457 malnourished children hospitalized from September 2009 to August 2011. Following a baseline observational pre-intervention period, all departments were randomized into either intervention or control arms. A computerized malnutrition-screening system was implemented in the intervention group to automatically trigger a dietetic referral in real time. Furthermore, the nutrition support team conducted an awareness campaign with healthcare workers and a leadership-based strategy to reinforce the message during the entire study period. Adherence to practice guidelines (daily weights, investigation of etiology for malnutrition, management by a dietitian and application of refeeding protocols) was compared between pre- and post-intervention periods in both the intervention and trial arms. RESULTS: When compared with the pre-intervention period, the clinical practices were significantly improved within the intervention arm for every outcome (P<0.01), whereas remained unchanged in the control arm. In addition, during the post-intervention period, malnutrition etiology investigation by physicians (adjusted odds ratio (OR) of 4.4, 95% confidence interval (CI) 1.7-11.8, P=0.003) and management by a dietitian (OR 2.7, 95% CI 1.0-6.9, P=0.046) occurred more frequently in the intervention clusters. CONCLUSIONS: Implementation of an electronic system to detect malnutrition in real time was associated with a rapid improvement in clinical practices for better care of hospitalized children.

Is it possible to limit the risks of thyroid surgery?

OBJECTIVE: Inferior laryngeal nerve (ILN) palsy and hypocalcemia remain the two most frequent major complications after thyroid surgery. Their occurrences may be explained by the influence of factors related to the patient, the surgical procedure, thyroid pathology, or the surgeon's technique. This study aims To assess whether systematically following a rigorous surgical technique during thyroidectomy affects postoperative complications and long-term patient recovery. METHODS: We conducted a multicenter, cross-sectional study of prospectively collected data in five high-volume referral centers enrolling all patients who underwent thyroid surgery between April 2008 and December 2009. Inferior laryngeal nerve (ILN) palsy and hypocalcemia were systematically assessed during hospitalization based on objective criteria. A six-month follow-up was conducted in cases of early complications. Multivariate regression models were computed to quantify their relationship with potential risk factors. RESULTS: A total of 3574 thyroid procedures were completed. Non-visualization of the ILN during dissection and a large thyroid mass were major risk factors for permanent ILN palsy (OR, 4.17 and 2.61, p<0.01) and persistent complications after initial injury (OR, 4.17 and 2.42, p<0.05). The presence of thyroiditis on the surgical specimen was an independent risk factor for permanent hypoparathyroidism and poor recovery after initial dysfunction (OR, 1.76 and 1.88, p<0.05). CONCLUSIONS: Thorough meticulous technique in thyroid surgery is a determinant of ILN function but fails to prevent persistent hypoparathyroidism.

Epidemiology of hepatitis C virus infection in seven European Union countries: a critical analysis of the literature. HENCORE Group. (Hepatitis C European Network for Co-operative Research.

Hepatitis C is now recognized as the most common infection causing chronic liver disease in the European population. Our aim was to assess the prevalence of the antibody to hepatitis C virus (HCV), and the incidence of HCV seroconversion in the general population and the main risk groups, namely intravenous drug users, haemodialysis and transfused patients, in seven countries of the European Union, by carrying out a critical analysis of the literature. Data sources used were the Medline database and a manual search using the key words: hepatitis C, prevalence, incidence, transmission, risk factors and epidemiology. Articles published between January 1990 and March 1997 were reviewed. Articles were reviewed according to a critical analysis method regarding title, type of article, study design, period and population, tests, results and their consistency with data. The tests performed were mainly second- or third-generation serological tests. The average prevalence rate in blood donors was 1%, with a north-south gradient ranging from 0.04% to 2%. Prevalence varied from 20% to 30% in haemodialysis patients. The incidence in transfused patients was less than 1% after 1991. The prevalence in intravenous drug users was about 80%. Multicentre studies conducted in larger samples are needed to obtain more accurate and reliable results, in particular. However, the epidemiological studies available allowed us to assess the magnitude of HCV infection in Europe.
