Rectal enema is an alternative to full mechanical bowel preparation for primary rectal cancer surgery.

AIM: According to the French GRECCAR III randomized trial, full mechanical bowel preparation (MBP) for rectal surgery decreases the rate of postoperative morbidity, in particular postoperative infectious complications, but MBP is not well tolerated by the patient. The aim of the present study was to determine whether a preoperative rectal enema (RE) might be an alternative to MBP. METHODS: An analysis was performed of 96 matched cohort patients undergoing rectal resection with primary anastomosis and protective ileostomy at two different university teaching hospitals, whose rectal cancer management was comparable except for the choice of preoperative bowel preparation (MBP or RE). Prospective databases were retrospectively analysed. RESULTS: Patients were well matched for age, gender, body mass index and Charlson index. The surgical approach and cancer characteristics (level above anal verge, stage and use of neoadjuvant therapy) were comparable between the two groups. Anastomotic leakage occurred in 10% of patients having MBP and in 8% having RE (P = 1.00). Pelvic abscess formation (6% vs 2%, P = 0.63) and wound infection (8% vs 15%, P = 0.55) were also comparable. Extra-abdominal infection (13% vs 13%, P = 1.00) and non-infectious abdominal complications such as ileus and bleeding (27% and 31%, P = 0.83) were not significantly different. Overall morbidity was comparable in the two groups (50% vs 54%, P = 0.83). CONCLUSION: A simple RE before rectal surgery seems not to be associated with more postoperative infectious complications nor a higher overall morbidity than MBP.

Archiving Primary Data: Solutions for Long-Term Studies.

The recent trend for journals to require open access to primary data included in publications has been embraced by many biologists, but has caused apprehension amongst researchers engaged in long-term ecological and evolutionary studies. A worldwide survey of 73 principal investigators (Pls) with long-term studies revealed positive attitudes towards sharing data with the agreement or involvement of the PI, and 93% of PIs have historically shared data. Only 8% were in favor of uncontrolled, open access to primary data while 63% expressed serious concern. We present here their viewpoint on an issue that can have non-trivial scientific consequences. We discuss potential costs of public data archiving and provide possible solutions to meet the needs of journals and researchers.

Cerebriforms cells in cerebrum: an unusual finding

Background. Mycosis Fungoides (MF) is the most common cutaneous T-cell lymphoma, and large cell trasformation (tMF) is an adverse prognostic event. Extra-cutaneous dissemination can occur in the course of the disease, but dissemination to the central nervous system (CNS) is uncommon. Moreover, CNS lymphomas are overall rare and most often of B-cell phenotype. We report a case of CNS large T-cell lymphoma presenting as multiple cerebral lesions in a patient with a history of MF. Methods. We report a case of a 33-year-old woman, known since the age of 16 for erythematous plaques thought to be atopic dermatitis, who developed, end 2012, multiple nodular skin lesions and peripheral adenopathies. Two skin lesions were biopsied simultaneously, and diagnosed as MF and tMF. A lymph node biopsy showed dermatopathic changes without lymphoma (Stage IIB). She received local treatment (UVB, PUVA and radiation therapy) and interferon therapy, and experienced almost complete remission. In 2015 neurological symptoms lead to evidence multiple cerebral lesions, suspicious for lymphoma, evaluated by stereotaxic biopsies. We compared histopathological and molecular features of these with previous skin specimens. After negative bone marrow staging biopsy, she was recently started on chemotherapy (MATRIX). Short follow-up shows rapidly worsening clinical conditions. Results. One of the initial skin biopsies showed atypical lymphoid cells with epidermotropism, Pautrier abcesses and CD4+ CD30- phenotype; the other revealed diffuse dermal infiltration by predominantly large cerebriform tumor cells with high proliferative fraction, and CD2−CD3 −CD4+/−CD7−CD30+ALK- EMA- non-cytotoxic immunophenotype. Altogether, these results led us to diagnose MF and tMF, respectively. The brain was infiltrated by large atypical lymphoid cells with cerebriform nuclei, somewhat anaplastic features and perivascular distribution. By immunohistochemistry, tumor cells were highly proliferative, with a CD2−CD3+CD5−CD7+CD30+ activated cytotoxic immunophenotype. A diagnosis of CD30+ cytotoxic peripheral T-cell lymphoma was retained. TRG and TRB clonality analyses revealed clonal rearrangements in skin and CNS biopsies, with identical patterns in both skin specimens but only minimally overlapping profiles when compared to the CNS sample. Der Pathologe 6 ? 2015 | 633 Conclusions. The reported case illustrates an uncommon finding of a CNS T-cell lymphoma in a patient with previous MF, questioning the clonal relationship between the two diseases and challenging the adequate classification of this CNS lymphoma as either a progression or a de novo lymphoma. Despite differences in immunophenotype and clonality patterns, this CNS lymphoma could possibly represent an aggressive divergent evolution of a primary cutaneous T-cell lymphoma. Additional sequencing is ongoing to try to solve the question.

Stereotactic body radiation therapy with helical tomotherapy for medical inoperable early-stage primary and second-primary non-small cell lung neoplasm : one-year outcome and toxicity analysis

Le cancer du poumon est la première cause de mortalité associée au cancer dans le monde. Le traitement curatif des tumeurs pulmonaires non-à-petites-cellules (NSCLC) diagnostiquées à un stade précoce se base sur une approche chirurgicale. Cependant, étant donné les comorbidités liées à la consommation de tabac, dont la bronchopneumopathie chronique occupe la première place, l'éligibilité chirurgicale pour ce type de cancer se trouve fréquemment limitée. Dans ce contexte, l'emploi de la radiothérapie stéréotaxique (SBRT) est une alternative valable chez les patients atteints d'un NSCLC primaire de stade précoce, et qui sont considérés inopérables à cause de leurs comorbidités. Depuis peu seulemement, le spectre de la SBRT a été élargi aux patients atteints d'un deuxième NSCLC primaire (SPLC), faisant suite à un premier NSCLC, traité avec un but curatif. Ils concernent donc des patients ayant déjà subits une intervention chirurgicale au préalable et qui présentent une réserve fonctionnelle pulmonaire extrêmement réduite. Le succès croissant de la SBRT résulte soit d'une efficacité thérapeutique comparables à la chirurgie, soit de sa toxicité qui semble limitée. À notre connaissance, seulement une étude a reporté des issues cliniques de patients affectés par des NSCLC primaires traités par SBRT. Cette dernière a utilisé la tomothérapie comme système d'irradiation (T-SBRT), sur un faible échantillon de patients (n = 27). Concernant l'irradiation des patients présentant des SPLC, la littérature disponible est pauvre et aucune publication a décrit l'utilisation de la T-SBRT. Ces éléments innovants ont donc motivé la rédaction d'un travail de thèse concernant les premières données cliniques de l'expérience faite au CHUV. Du point de vue des effets secondaires, si la pneumonie actinique précoce et tardive survenant au niveau du champ d'irradiation est désormais une complication iatrogène bien connue de la SBRT, une seule étude s'est intéressée à ce sujet dans le cadre de la T-SBRT. De plus, une entité bénigne et transitoire de pneumonie ( ?) a été reconnue depuis peu : la pneumonie organisée radio-induite (OP). Celle-ci semble se chevaucher comme un autre effet iatrogène à l'extérieur du champ d'irradiation. Originellement, cette dernière avait été rapportée dans les suites de la radiothérapie pour les cancer du sein. Elle a été décrite comme étant initialement limitée au champ d'irradiation et successivement pouvant s'étendre dynamiquement en dehors de celui-ci. Nous avons donc supposé que des infiltrats de OP peuvent être présents chez des patients asymptomatiques, et que ce dynamisme pourrait être identifié déjà au sein du champ d'irradiation. Notre étude a démontré que le traitement par T-SBRT garde des issues cliniques très encourageantes, aussi bien pour les tumeurs primaires que pour les SPLC. Entre autre, ce traitement semble avoir une toxicité limitée, et l'existence vraisemblable de la OP, déjà au sein du champ d'irradiation, peut aider les radiologues à différencier les infiltrats radio-induits d'une une récidive tumorale.

Multimorbidity in primary care : protocol of a national cross-sectional study in Switzerland.

INTRODUCTION: With the ageing of the population and the general improvement of care, an increasing number of people are living with multiple chronic health conditions or 'multimorbidity'. Multimorbidity often implies multiple medical treatments. As a consequence, the risk of adverse events and the time spent by patients for their treatments increase exponentially. In many cases, treatment guidelines traditionally defined for single conditions are not easily applicable. Primary care for individuals with multimorbidity requires complex patient-centred care and good communication between the patient and the general practitioner (GP). This often includes prioritising among the different chronic conditions. METHODS AND ANALYSIS: The main objectives of this study are to describe the burden related to multimorbidity (disease-related burden and burden of treatment) in primary care and to identify the factors influencing it. Other objectives include evaluating patients' perception of treatment burden and quality of life, assessing factors influencing that perception, and investigating prioritisation in the management of multimorbidity from the perspectives of GPs and patients. For this cross-sectional study, patient enrolment will take place in GP's private practices across Switzerland. A convenient sample of 100 GPs will participate; overall, 1000 patients with at least three chronic health conditions will be enrolled. Data will be collected as paper-based questionnaires for GPs and delayed telephone interview questionnaires for patients. GPs will provide demographic and practice-related data. In addition, each GP will complete a paper-based questionnaire for each patient that they enrol. Each patient will complete a telephone interview questionnaire. ETHICS AND DISSEMINATION: This study has been approved by the research ethics committee of Canton Vaud, Switzerland (Protocol 315/14). The results of the study will be reported in international peer-reviewed journals.

Role of microRNAs in the age-associated decline of pancreatic beta cell function in rat islets.

AIMS/HYPOTHESIS: Ageing can lead to reduced insulin sensitivity and loss of pancreatic beta cell function, predisposing individuals to the development of diabetes. The aim of this study was to assess the contribution of microRNAs (miRNAs) to age-associated beta cell dysfunction. METHODS: The global mRNA and miRNA profiles of 3- and 12-month-old rat islets were collected by microarray. The functional impact of age-associated differences in miRNA expression was investigated by mimicking the observed changes in primary beta cells from young animals. RESULTS: Beta cells from 12-month-old rats retained normal insulin content and secretion, but failed to proliferate in response to mitotic stimuli. The islets of these animals displayed modifications at the level of several miRNAs, including upregulation of miR-34a, miR-124a and miR-383, and downregulation of miR-130b and miR-181a. Computational analysis of the transcriptomic modifications observed in the islets of 12-month-old rats revealed that the differentially expressed genes were enriched for miR-34a and miR-181a targets. Indeed, the induction of miR-34a and reduction of miR-181a in the islets of young animals mimicked the impaired beta cell proliferation observed in old animals. mRNA coding for alpha-type platelet-derived growth factor receptor, which is critical for compensatory beta cell mass expansion, is directly inhibited by miR34a and is likely to be at least partly responsible for the effects of this miRNA. CONCLUSIONS/INTERPRETATION: Changes in the level of specific miRNAs that occur during ageing affect the proliferative capacity of beta cells. This might reduce their ability to expand under conditions of increased insulin demand, favouring the development of type 2 diabetes.

Prise en charge de la candidose oesophagienne en médecine de premier recours [Management of the esophageal candidiasis by the primary care physician].

La candidose oesophagienne est l'une des infections opportunistes les plus fréquentes chez les patients infectés par le VIH. Ce diagnostic se rencontre également chez des patients sans immunodéficience manifeste. Certains facteurs de risque sont également associés à cette pathologie, tels que les traitements corticoïdes systémiques et inhalés ou les traitements par inhibiteurs de la pompe à protons et les antihistaminiques H2. En l'absence de facteur de risque identifié, un déficit immunitaire primaire devrait être recherché. La prévention de la candidose oesophagienne est basée en premier lieu sur l'identification des facteurs de risque, ainsi qu'un meilleur contrôle de ceux-ci. Cet article présente en détail la physio-pathologie, la clinique et la prise en charge par le médecin de premier recours de la candidose oesophagienne. Nous aborderons également les moyens de prévention de la candidose oesophagienne quand il y a lieu. Esophageal candidiasis is one of the most common opportunistic infections in patients infected by human immunodeficiency virus (HIV). This pathology is also found in patients without overt immunodeficiency. Other risk factors are known to be associated with this disease like inhaled or systemic corticosteroid treatment or proton-pump inhibitors and H2 receptor antagonists. In the absence of identified risk factors, a primary immune deficiency should be sought. Prevention of esophageal candidiasis is based primarily on the identification of risk factors, and a better control of them. This article presents a review of the physiopathology, clinical presentation and management of esophageal candidiasis by primary care physicians. We will also discuss ways of preventing esophageal candidiasis when necessary.

Statines en prévention primaire: comment décider avec le patient [Statins in primary prevention: how to share the decision?].

Long-term treatment of hypercholesterolemia with statins diminishes the risk of cardiovascular events. Statins are recommended in secondary prevention of cardiovascular disease. In the absence of preexisting cardiovascular disease, the decision to start a statin or not is most often made by the general practitioner and his patient. An interactive decision aid, developed by the Mayo Clinic, has just been translated in French and adapted to the Swiss epidemiology of cardiovascular risk factors, with the aim of promoting shared decision-making. This paper reviews the conditions and potential benefits of shared decision-making about statin therapy in primary prevention.

Initiation of rivaroxaban in patients with nonvalvular atrial fibrillation at the primary care level: the Swiss Therapy in Atrial Fibrillation for the Regulation of Coagulation (STAR) Study.

BACKGROUND: Rivaroxaban has become an alternative to vitamin-K antagonists (VKA) for stroke prevention in non-valvular atrial fibrillation (AF) patients due to its favourable risk-benefit profile in the restrictive setting of a large randomized trial. However in the primary care setting, physician's motivation to begin with rivaroxaban, treatment satisfaction and the clinical event rate after the initiation of rivaroxaban are not known. METHODS: Prospective data collection by 115 primary care physicians in Switzerland on consecutive nonvalvular AF patients with newly established rivaroxaban anticoagulation with 3-month follow-up. RESULTS: We enrolled 537 patients (73±11years, 57% men) with mean CHADS2 and HAS-BLED-scores of 2.2±1.3 and 2.4±1.1, respectively: 301(56%) were switched from VKA to rivaroxaban (STR-group) and 236(44%) were VKA-naïve (VN-group). Absence of routine coagulation monitoring (68%) and fixed-dose once-daily treatment (58%) were the most frequent criteria for physicians to initiate rivaroxaban. In the STR-group, patient's satisfaction increased from 3.6±1.4 under VKA to 5.5±0.8 points (P<0.001), and overall physician satisfaction from 3.9±1.3 to 5.4±0.9 points (P<0.001) at 3months of rivaroxaban therapy (score from 1 to 6 with higher scores indicating greater satisfaction). In the VN-group, both patient's (5.4±0.9) and physician's satisfaction (5.5±0.7) at follow-up were comparable to the STR-group. During follow-up, 1(0.19%; 95%CI, 0.01-1.03%) ischemic stroke, 2(0.37%; 95%CI, 0.05-1.34%) major non-fatal bleeding and 11(2.05%; 95%CI, 1.03-3.64%) minor bleeding complications occurred. Rivaroxaban was stopped in 30(5.6%) patients, with side effects being the most frequent reason. CONCLUSION: Initiation of rivaroxaban for patients with nonvalvular AF by primary care physicians was associated with a low clinical event rate and with high overall patient's and physician's satisfaction.

Sickness certification in primary care: a survey on views and practices among Swiss physicians.

QUESTIONS UNDER STUDY: Studies from several countries (Scandinavia, United Kingdom) report that general practitioners (GPs) experience problems in sickness certification. Our study explored views of Swiss GPs towards sickness certification, their practice and experience, professional skills and problematic interactions with patients. METHODS: We conducted an online survey among GPs throughout Switzerland, exploring behaviour of physicians, patients and employers with regard to sickness certification; GPs' views about sickness certification; required competences for certifying sickness absence, and approaches to advance their competence. We piloted the questionnaire and disseminated it through the networks of the five Swiss academic institutes for primary care. RESULTS: We received 507 valid responses (response rate 50%). Only 43/507 GPs experienced sickness certification as problematic per se, yet 155/507 experienced problems in sickness certification at least once a week. The 507 GPs identified estimating a long-term prognosis about work capacity (64%), handling conflicts with patients (54%), and determining the reduction of work capacity (42%) as problematic. Over 75% would welcome special training opportunities, e.g., on sickness certifications during residency (93%), in insurance medicine (81%), and conflict management (80%). CONCLUSION: Sickness certification as such does not present a major problem to Swiss GPs, which contrasts with the experience in Scandinavian countries and in the UK. Swiss GPs did identify specific tasks of sickness certification as problematic. Training opportunities on sick-leave certification and insurance medicine in general were welcomed.

The role of the microRNAs in the age-associated oancreatic β-cell dysfunction

Le corps humain emploie le glucose comme source principale d'énergie. L'insuline, sécrétée par les cellules ß-pancreatiques situées dans les îlots de Langerhans, est l'hormone principale assurant un maintien constant du taux de glucose sanguin (glycémie). Les prédispositions génétiques, le manque d'activité physique et un régime déséquilibré peuvent entraîner une perte de sensibilité à l'insuline et des taux de glucose dans le sang élevé (hyperglycémie), une condition nommée diabète de type 2. Cette maladie est initiée par une sensibilité diminuée à l'insuline dans les tissus périphériques, entraînant une demande accrue en insuline. Cette pression continue finie par épuiser les cellules ß-pancreatiques, qui sécrètent alors des niveaux d'insuline insuffisant en trainant l'apparition du diabète. Le vieillissement est un facteur de risque important pour les maladies métaboliques dont le diabète de type 2 faits partis. En effet la majeure partie des diabétiques de type 2 ont plus de 45 ans. Il est connu que le vieillissement entraine une perte de sensibilité à l'insuline, une sécrétion altérée d'insuline, une baisse de réplication et une plus grande mort des ß-cellules pancréatiques. Le but de ma thèse était de mieux comprendre les mécanismes contribuante au dysfonctionnement des cellules ß- pancréatiques lors du vieillissement. Les travaux du « Human Genome Project » ont révélés que seulement 2% de notre génome code pour des protéines. Le reste non-codant fut alors désigné sous le nom de « ADN déchets ». Cependant, l'étude approfondie de cet ADN non-codant ces dernières deux décennies a démontré qu'une grande partie code pour des «MicroARNs », des ARNs courts (20-22 nucleotides) découverts en 1997 chez le vers C.elegans. Depuis lors ces molécules ont été intensivement étudiées, révélant un rôle crucial de ces molécules dans la fonction et la survie des cellules en conditions normales et pathologiques. Le but de cette thèse était d'étudier le rôle des microARNs dans le dysfonctionnement des cellules ß lors du vieillissement. Nos données suggèrent qu'ils peuvent jouer un rôle tantôt salutaire, tantôt nocif sur les cellules ß. Par exemple, certains microARNs réduisent la capacité des cellules ß à se multiplier ou réduisent leur survie, alors que d'autres protègent ces cellules contre la mort. Pour conclure, nous avons démontré les microARNs jouent un rôle important dans le dysfonctionnement des cellules ß lors du vieillissement. Ces nouvelles découvertes préparent le terrain pour la conception de futures stratégies visant à améliorer la résistance des cellules ß pancréatiques afin de trouver de nouveaux traitements du diabète de type 2. -- Le diabète de type 2 est une maladie métabolique due à la résistance à l'action de l'insuline des tissus cibles combinée à l'incapacité des cellules ß pancréatiques à sécréter les niveaux adéquats d'insuline. Le vieillissement est associé à un déclin global des fonctions de l'organisme incluant une diminution de la fonction et du renouvellement des cellules ß pancréatiques. Il constitue ainsi un risque majeur de développement des maladies métaboliques dont le diabète de type 2. Le but de cette thèse était d'étudier le rôle des microARNs (une classe d'ARN non- codants) dans le dysfonctionnement lié au vieillissement des cellules ß. L'analyse par microarray des niveaux d'expression des microARN dans les îlots pancréatiques de rats Wistar mâles âgés de 3 et 12 mois nous a permis d'identifier de nombreux changements d'expression de microARNs associés au vieillissement. Afin d'étudier les liens entre ces modifications et le déclin des cellules ß, les changements observés lors du vieillissement ont été reproduits spécifiquement dans une lignée cellulaire, dans des cellules ß primaires de jeune rats ou de donneurs humains sains. La diminution du miR-181a réduit la prolifération des cellules ß, tandis que la diminution du miR-130b ou l'augmentation du miR-383 protège contre l'apoptose induite par les cytokines. L'augmentation du miR-34a induit l'apoptose et inhibe la prolifération des cellules ß en réponse aux hormones Exendin-4 et prolactine et au facteur de croissance PDGF-AA. Cette perte de capacité réplicative est similaire à celle observée dans des cellules ß de rats âgés de 12 mois. Dans la littérature, la perte du récepteur au PDGF-r-a est associée à la diminution de la capacité proliférative des cellules ß observée lors du vieillissement. Nous avons pu démontrer que PDGF-r-a est une cible directe de miR- 34a, suggérant que l'effet néfaste de miR-34a sur la prolifération des cellules ß est, du moins en partie, lié à l'inhibition de l'expression de PDGF-r-a. L'expression de ce miR est aussi plus élevée dans le foie et le cerveau des animaux de 1 an et augmente avec l'âge dans les ilôts de donneurs non-diabétiques. Ces résultats suggèrent que miR-34a pourrait être non seulement impliqué dans l'affaiblissement des fonctions pancréatiques associé à l'âge, mais également jouer un rôle dans les tissus cibles de l'insuline et ainsi contribuer au vieillissement de l'organisme en général. Pour conclure, les travaux obtenus durant cette thèse suggèrent que des microARNs sont impliqués dans le dysfonctionnement des cellules ß pancréatiques durant le vieillissement. -- Type 2 diabetes is a metabolic disease characterized by impaired glucose tolerance, of the insulin sensitive tissues and insufficient insulin secretion from the pancreatic ß-cells to sustain the organism demand. Aging is a risk factor for the majority of the metabolic diseases including type 2 diabetes. With aging is observed a decline in all body function, due to decrease both in cell efficiency and renewal. The aim of this thesis was to investigate the potential role of microRNAs (short non- coding RNAs) in the pancreatic ß-cell dysfunction associated with aging. Microarray analysis of microRNA expression profile in pancreatic islets from 3 and 12 month old Wistar male rats revealed important changes in several microRNAs. To further study the link between those alterations and the decline of ß-cells, the changes observed in old rats were mimicked in immortalized ß-cell lines, primary young rat and human islets. Downregulation of miR-181a inhibited pancreatic ß-cell proliferation in response to proliferative drugs, whereas downregulation of miR-130b and upregulation of miR-383 protected pancreatic ß-cells from cytokine stimulated apoptosis. Interestingly, miR-34a augmented pancreatic ß-cell apoptosis and inhibited ß-cell proliferation in response to the proliferative chemicals Exendin-4, prolactin and PDGF-AA. This loss of replicative capacity is reminiscent of what we observed in pancreatic ß-cells isolated from 12 month old rats. We further observed a correlation between the inhibitory effect of miR-34a on pancreatic ß-cell proliferation and its direct interfering effect of this microRNA on PDGF-r-a, which was previously reported to be involved in the age-associated decline of pancreatic ß-cell proliferation. Interestingly miR-34a was upregulated in the liver and brain of 1 year old animals and positively correlated with age in pancreatic islets of normoglycemic human donors. These results suggest that miR-34a might be not only involved in the age-associated impairment of the pancreatic ß-cell functions, but also play a role in insulin target tissues and contribute to the aging phenotype on the organism level. To conclude, we have demonstrated that microRNAs are indeed involved in the age-associated pancreatic ß-cell dysfunction and they can play both beneficial and harmful roles in the context of pancreatic ß-cell aging.

"Hit the primary": A paradigm shift in the treatment of metastatic prostate cancer?

Patients with metastatic prostate cancer (PC) represent a heterogeneous group with survival rates varying between 13 and 75 months. The current standard treatment in this setting is hormonal therapy, with or without docetaxel-based chemotherapy. In the era of individualized medicine, however, maximizing treatment options, especially in long-term surviving patients with limited disease burden, is of capital importance. Emerging data, mainly from retrospective surgical series, show survival benefits in men diagnosed with metastatic PC following definitive therapy for the prostate. Whether the irradiation of primary tumor in a metastatic disease might improve the therapeutic ratio in association with systemic treatments remains investigational. In this scenario, modern radiation therapy (RT) can play a significant role owing to its intrinsic capability to act as a more general immune response modifier, as well as to the potentially better toxicity profile compared to surgery. Preclinical data, clinical experience, and challenges in local treatment in de novo metastatic PC are reviewed and discussed.

Quality assessment of primary care for common mental disorders in isolated communities: Taking advantage of health records.

INTRODUCTION: This article is part of a research study on the organization of primary health care (PHC) for mental health in two of Quebec's remote regions. It introduces a methodological approach based on information found in health records, for assessing the quality of PHC offered to people suffering from depression or anxiety disorders. METHODS: Quality indicators were identified from evidence and case studies were reconstructed using data collected in health records over a 2-year observation period. Data collection was developed using a three-step iterative process: (1) feasibility analysis, (2) development of a data collection tool, and (3) application of the data collection method. The adaptation of quality-of-care indicators to remote regions was appraised according to their relevance, measurability and construct validity in this context. RESULTS: As a result of this process, 18 quality indicators were shown to be relevant, measurable and valid for establishing a critical quality appraisal of four recommended dimensions of PHC clinical processes: recognition, assessment, treatment and follow-up. CONCLUSIONS: There is not only an interest in the use of health records to assess the quality of PHC for mental health in remote regions but also a scientific value for the rigorous and meticulous methodological approach developed in this study. From the perspective of stakeholders in the PHC system of care in remote areas, quality indicators are credible and provide potential for transferability to other contexts. This study brings information that has the potential to identify gaps in and implement solutions adapted to the context.
