Un diagnostic de maladie coeliaque peut en cacher un autre [A diagnosis of coeliac disease can hide an alternative diagnosis]

The Common variable Immunodeficiency (CVID) is next to the selective IgA-deficiency the most frequent primary immunodeficiency syndrome. Because of its variable clinical manifestations and age of declaration, CVID can mimic different other pathologies and is therefore frequently diagnosed in a later stage of the disease. However, as a consequence of late diagnosis, irreversible organ damage can have occurred which could have been prevented by early treatment. Therefore, early diagnosis of CVID by the general practitioner in patients with recurrent infections or other typical clinical manifestations is of great importance.

Syndromes vertigineux en pratique ambulatoire [Dizziness in a general practice]

The symptoms of vertigo are frequent complaints. With the anamnestic features and the quite long and tiresome clinical examination alone, the general practitioner should make the difference between a benign peripheral and a potentially fatal central pathology. A good knowledge of the anamnestic and clinical particularities and the diagnostic manoeuvres of the main types of vertigo allows in about two thirds of the cases to distinguish their origin. If a central origin is suspected or if the etiology is uncertain, the patient should be referred to a neurologist for further examination and radiological investigations.

Differential diagnosis of leukocoria and strabismus, first presenting signs of retinoblastoma.

Leukocoria in infants is always a danger signal as retinoblastoma, a malignant retinal tumor, is responsible for half of the cases in this age group. More common signs should also be considered suspicious until proved otherwise, such as strabismus, the second most frequent sign of retinoblastoma. Less frequent manifestations are inflammatory conditions resistant to treatment, hypopyon, orbital cellulitis, hyphema or heterochromia. Other causal pathologies, including persistent hyperplastic primary vitreous (PHPV), Coats' disease, ocular toxocariasis or retinopathy of prematurity, may also manifest the same warning signs and require specialized differential diagnosis. Members of the immediate family circle are most likely to notice the first signs, the general practitioner, pediatrician or general ophthalmologist the first to be consulted. On their attitude will depend the final outcome of this vision and life-threatening disease. Early diagnosis is vital.

Prévention des infections chez les voyageurs immunosupprimés [Prevention of infection in immunocompromised travelers].

Every year there are more immunocompromised patients with a better quality of life and, therefore, that travel more frequently. While traveling, patients may be exposed to several infections, such as traveler's diarrhea or malaria, which can be associated with a high rate of complications in this population. An appropriate strategy for the prevention of travel-related infections is essential, including education about hygiene measures, vaccinations and prescription of a tailored antimicrobial prophylaxis/stand-by treatment, according to the type of immunosuppression. Potential drug interactions, particularly between antimalaric and immunosuppressive drugs, must also be considered for decision taking. Collaboration between the general practitioner and the travel medicine and infectious diseases specialists is highly recommended to improve the management of these patients.

Current cardiovascular risk management patterns with special focus on lipid lowering in daily practice in Switzerland.

Background: There may be a considerable gap between LDL cholesterol (LDL-C) and blood pressure (BP) goal values recommended by the guidelines and results achieved in daily practice. Design Prospective cross-sectional survey of cardiovascular disease risk profiles and management with focus on lipid lowering and BP lowering in clinical practice. Methods: In phase 1, the cardiovascular risk of patients with known lipid profile visiting their general practitioner was anonymously assessed in accordance to the PROCAM-score. In phase 2, high-risk patients who did not achieve LDL-C goal less than 2.6 mmol/l in phase 1 could be further documented. Results: Six hundred thirty-five general practitioners collected the data of 23 892 patients with known lipid profile. Forty percent were high-risk patients (diabetes mellitus or coronary heart disease or PROCAM-score >20%), compared with 27% estimated by the physicians. Goal attainment rate was almost double for BP than for LDL-C in high-risk patients (62 vs. 37%). Both goals were attained by 25%. LDL-C values in phase 1 and 2 were available for 3097 high-risk patients not at LDL-C goal in phase 1; 32% of patients achieved LDL-C goal of less than 2.6 mmol/l after a mean of 17 weeks. The most successful strategies for LDL-C reduction were implemented in only 22% of the high-risk patients. Conclusion: Although patients at high cardiovascular risk were treated more intensively than low or medium risk patients, the majority remained insufficiently controlled, which is an incentive for intensified medical education. Adequate implementation of Swiss and International guidelines would expectedly contribute to improved achievement of LDL-C and BP goal values in daily practice.

Lorsque le patient obèse ne perd pas de poids ou continue a en prendre... [When the obese patient can't lose any weight or keeps putting some on].

The traditional obesity treatments have proven to be ineffective in the long-term. The presence of eating disorders frequently explains this phenomena. Eating educational and behavioral aspects must be addressed in a practical way so that patients could gradually become aware of their behavior towards food as well as internal sensations associated with hunger, satiety, craving and pleasure. Finally, the link between emotions and compulsive eating behaviors during and between meals is an essential aspect that the general practitioner can help the patient to understand. A specialized psychological treatment can then be considered when the patient shows sufficient motivation and consciousness.

Ultra-rapid opiate detoxification using deep sedation and prior oral buprenorphine preparation: long-term results.

BACKGROUND: New methods of ultra-rapid opiate detoxification (URD) under intravenous sedation have been criticized because of limited data on safety and long-term follow-up. Premedication with buprenorphine has been advocated to improve safety by decreasing vomiting. Prior research has not explored URD in socially impaired patients. METHOD: Sixteen patients were detoxified with URD and prospectively evaluated over at least 30 months. Data of this procedure were compared with those of our previous study without buprenorphine preparation (Drug Alcohol Depend. 52(3) (1998) 243). The 16 patients were followed up by a general practitioner (GP) before and after URD. The GPs also supervised the 7-day course of buprenorphine treatment prescribed for the 16 patients prior to URD. RESULTS: During the procedure, only one episode of vomiting occurred instead of 13 out of 20 in our previous study. Post-procedure, only two patients experienced moderate withdrawal symptoms, such as persistent nausea, abdominal cramps and vomiting lasting from 24 to 48 h, in comparison with most patients in the previous study without buprenorphine. After a period of at least 30 months (36.0+/-6.38), the 16 patients were still alive and were regularly monitored by their GP. Only two of the 16 never relapsed after URD and reported total opiate abstinence. Fourteen patients relapsed; 12 of these were prescribed a licensed methadone substitution program and two were still using heroin. CONCLUSION: In this small sample, the data indicated that URD with buprenorphine preparation was safe and that it markedly decreased post-procedure morbidity. No patient died over a minimum 30-month follow-up period. Furthermore, the procedure was employed with socially impaired patients. In the long term, a few patients were still free of opiates, while the majority opted for a methadone maintenance program, showing that URD can serve as one possible step in a long-term treatment program.

Urgences vitales au cabinet médical: implications pour la formation et l'equipement du médecin de premier recours [Life-threatening emergencies at the office: implications for medical education and equipment of the primary care physician].

Every medical practitioner is confronted on a daily basis with emergencies. Among these, life-threatening emergencies can have disastrous consequences in term of morbidity and mortality; 22 cardiac arrests and 10 deaths were reported among the 1,650 Swiss practices during a 5 year period. The occurrence of life-threatening emergencies at the office necessitates, according to the type and place of the practice, the skills of the practitioner and the organization of his practice, the implementation of procedures, equipments (for example room equipped with a defibrillator, respiratory nebulizer, splints, emergency drugs) and specific continuous education programs that should be encouraged and made available to the whole medical corporation.

Medical record search engines, using pseudonymised patient identity: an alternative to centralised medical records

Purpose The purpose of our multidisciplinary study was to define a pragmatic and secure alternative to the creation of a national centralised medical record which could gather together the different parts of the medical record of a patient scattered in the different hospitals where he was hospitalised without any risk of breaching confidentiality. Methods We first analyse the reasons for the failure and the dangers of centralisation (i.e. difficulty to define a European patients' identifier, to reach a common standard for the contents of the medical record, for data protection) and then propose an alternative that uses the existing available data on the basis that setting up a safe though imperfect system could be better than continuing a quest for a mythical perfect information system that we have still not found after a search that has lasted two decades. Results We describe the functioning of Medical Record Search Engines (MRSEs), using pseudonymisation of patients' identity. The MRSE will be able to retrieve and to provide upon an MD's request all the available information concerning a patient who has been hospitalised in different hospitals without ever having access to the patient's identity. The drawback of this system is that the medical practitioner then has to read all of the information and to create his own synthesis and eventually to reject extra data. Conclusions Faced with the difficulties and the risks of setting up a centralised medical record system, a system that gathers all of the available information concerning a patient could be of great interest. This low-cost pragmatic alternative which could be developed quickly should be taken into consideration by health authorities.

Forensic science culture

Heretofore the issue of quality in forensic science is approached through a quality management policy whose tenets are ruled by market forces. Despite some obvious advantages of standardization of methods allowing interlaboratory comparisons and implementation of databases, this approach suffers from a serious lack of consideration for forensic science as a science. A critical study of its principles and foundations, which constitutes its culture, enables to consider the matter of scientific quality through a new dimension. A better understanding of what pertains to forensic science ensures a better application and improves elementary actions within the investigative and intelligence processes as well as the judicial process. This leads to focus the attention on the core of the subject matter: the physical remnants of the criminal activity, namely, the traces that produce information in understanding this activity. Adapting practices to the detection and recognition of relevant traces relies on the apprehension of the processes underlying forensic science tenets (Locard, Kirk, relevancy issue) and a structured management of circumstantial information (directindirect information). This is influenced by forensic science education and training. However, the lack of homogeneity with regard to the scientific nature and culture of the discipline within forensic science practitioners and partners represents a real challenge. A sound and critical reconsideration of the forensic science practitioner's roles (investigator, evaluator, intelligence provider) and objectives (prevention, strategies, evidence provider) within the criminal justice system is a means to strengthen the understanding and the application of forensic science. Indeed, the whole philosophy is aimed at ensuring a high degree of excellence, namely, a dedicated scientific quality.

Anomalies vasculaires: exemple du syndrome de Klippel-Trenaunay [Vascular anomalies].

Les anomalies vasculaires constituent des affections rares présentes dès la naissance. Elles sont classées selon leur histologie en tumeurs ou malformations vasculaires. La connaissance de ces anomalies par le médecin de famille est importante, permettant ainsi leur diagnostic, qui repose essentiellement sur la clinique. Les caractéristiques anatomiques et hémodynamiques de l'anomalie sont précisées par l'angiologue grâce à l'écho-Doppler. Cet examen permet un suivi de la lésion et le diagnostic d'éventuelles complications. Un bilan radiologique peut compléter cette évaluation avant discussion multidisciplinaire en vue d'un traitement parfois difficile. Dans cet article, un bref aperçu des malformations vasculaires et de leur prise en charge multidisciplinaire est discuté, en particulier dans le cas du syndrome de Klippel-Trenaunay. Vascular anomalies are rare conditions that could be observed at all ages. They are classified, according to their histology, in vascular tumors or vascular malformations. The general practitioner plays a significant role in diagnosis and patient management, diagnosis being suspected on clinical history. In case of vascular anomaly, ultrasound-Doppler assessment is helpful to characterize morphologic and hemodynamic changes of the lesion and permits to monitor the evolution and to detect complications. Further investigations are often necessary prior to multidisciplinary management. In this article, a brief overview of vascular anomalies, their multidisciplinary management and the exemple of Klippel-Trenaunay syndrome are presented.

Emergency department visits for non-life-threatening conditions : evolution over 13 years in a Swiss urban teaching hospital

INTRODUCTION: A large proportion of visits to our Emergency Department (ED) are for non-life-threatening conditions. We investigated whether patients' characteristics and reasons for consultation had changed over 13 years. METHODS: Consecutive adult patients with non-life-threatening conditions at triage were included in the spring of 2000 and in the summer of 2013. In both years patients completed a similar questionnaire, which addressed their reasons for consultation and any previous consultation with a general practitioner (GP). RESULTS: We included 581 patients in 2013 vs 516 in 2000, with a mean age of 44.5 years vs 46.4 years (p=0.128). Of these patients, 54.0% vs 57.0% were male (p=0.329), 55.5% vs 58.7% were Swiss (p=0.282), 76.4% were registered with a GP in both periods, but self-referral increased from 52.0% to 68.8% (p<0.001); 57.7% vs., 58.3% consulted during out-of- hours (p=0.821). Trauma-related visits decreased from 34.2% to 23.7% (p<0.001). Consultations within 12 hours of onset of symptoms dropped from 54.5% to 30.9%, and delays of ≥1 week increased from 14.3% to 26.9% (p<0.001). The primary motive for self-referral remained unawareness of an alternative, followed in 2013 by dissatisfaction with the GP's treatment or appointment. Patients who believed that their health problem would not require hospitalisation increased from 52.8% to 74.2% and those who were actually hospitalised decreased from 24.9% to 13.9% (all p<0.001). CONCLUSION: The number of visits for non-life-threatening consultations continue to increase. Our ED is used by a large proportion of patients as a convenient alternative source of primary care.

Sensitivity analysis, dominant factors, and robustness of the ECETOC TRA v3, Stoffenmanager 4.5, and ART 1.5 occupational exposure models

Occupational exposure modeling is widely used in the context of the E.U. regulation on the registration, evaluation, authorization, and restriction of chemicals (REACH). First tier tools, such as European Centre for Ecotoxicology and TOxicology of Chemicals (ECETOC) targeted risk assessment (TRA) or Stoffenmanager, are used to screen a wide range of substances. Those of concern are investigated further using second tier tools, e.g., Advanced REACH Tool (ART). Local sensitivity analysis (SA) methods are used here to determine dominant factors for three models commonly used within the REACH framework: ECETOC TRA v3, Stoffenmanager 4.5, and ART 1.5. Based on the results of the SA, the robustness of the models is assessed. For ECETOC, the process category (PROC) is the most important factor. A failure to identify the correct PROC has severe consequences for the exposure estimate. Stoffenmanager is the most balanced model and decision making uncertainties in one modifying factor are less severe in Stoffenmanager. ART requires a careful evaluation of the decisions in the source compartment since it constitutes ∼75% of the total exposure range, which corresponds to an exposure estimate of 20-22 orders of magnitude. Our results indicate that there is a trade off between accuracy and precision of the models. Previous studies suggested that ART may lead to more accurate results in well-documented exposure situations. However, the choice of the adequate model should ultimately be determined by the quality of the available exposure data: if the practitioner is uncertain concerning two or more decisions in the entry parameters, Stoffenmanager may be more robust than ART.

Acute schistosomiasis: a risk underestimated by travelers and a diagnosis frequently missed by general practitioners-a cluster analysis of 42 travelers.

BACKGROUND: In 2011, a patient was admitted to our hospital with acute schistosomiasis after having returned from Madagascar and having bathed at the Lily waterfalls. On the basis of this patient's indication, infection was suspected in 41 other subjects. This study investigated (1) the knowledge of the travelers about the risks of schistosomiasis and their related behavior to evaluate the appropriateness of prevention messages and (2) the diagnostic workup of symptomatic travelers by general practitioners to evaluate medical care of travelers with a history of freshwater exposure in tropical areas. METHODS: A questionnaire was sent to the 42 travelers with potential exposure to schistosomiasis. It focused on pre-travel knowledge of the disease, bathing conditions, clinical presentation, first suspected diagnosis, and treatment. RESULTS: Of the 42 questionnaires, 40 (95%) were returned, among which 37 travelers (92%) reported an exposure to freshwater, and 18 (45%) were aware of the risk of schistosomiasis. Among these latter subjects, 16 (89%) still reported an exposure to freshwater. Serology was positive in 28 (78%) of 36 exposed subjects at least 3 months after exposure. Of the 28 infected travelers, 23 (82%) exhibited symptoms and 16 (70%) consulted their general practitioner before the information about the outbreak had spread, but none of these patients had a serology for schistosomiasis done during the first consultation. CONCLUSIONS: The usual prevention message of avoiding freshwater contact when traveling in tropical regions had no impact on the behavior of these travelers, who still went swimming at the Lily waterfalls. This prevention message should, therefore, be either modified or abandoned. The clinical presentation of acute schistosomiasis is often misleading. General practitioners should at least request an eosinophil count, when confronted with a returning traveler with fever. If eosinophilia is detected, it should prompt the search for a parasitic disease.

Réhabilitation améliorée après chirurgie--L'ere de la prise en charge optimale du patient chirurgical [Enhanced Recovery After Surgery--optimal management of the surgical patient].

Enhanced Recovery After Surgery (ERAS) is a multimodal, standardized and evidence-based perioperative care pathway. With ERAS, postoperative complications are significantly lowered, and, as a secondary effect, length of hospital stay and health cost are reduced. The patient recovers better and faster allowing to reduce in addition the workload of healthcare providers. Despite the hospital discharge occurs sooner, there is no increased charge of the outpatient care. ERAS can be safely applied to any patient by a tailored approach. The general practitioner plays an essential role in ERAS by assuring the continuity of the information and the follow-up of the patient.
