Traitement des tumeurs malignes du foie par radiologie interventionnelle: techniques ablatives [Interventional radiology procedures for malignancies of the liver: ablation procedures].

Percutaneous ablative procedures allow curative treatment of stage BCLC 0 or BCLC A hepatocellular carcinoma, as well as liver metastases of colorectal cancer. Several methods exist including radiofrequency ablation, the most commonly used. These techniques can be used in combination with surgical excision or alone if surgery is contraindicated. They are associated with significantly reduced mortality as compared to surgery.

Suivi thérapeutique des médicaments (I). Les principes [Principles of therapeutic drug monitoring]

Requesting a blood level measurement of a drug is part of the global approach known as "Therapeutic Drug Monitoring". Diverse situations require this monitoring approach, such as inadequate response to treatment or organ failure. Every drug however does not possess all the characteristics for a TDM program. The therapeutic range of a TDM drug has indeed to be narrow and its interindividual pharmacokinetic variability to be wide. As the development of new drugs is currently slowing down, the precise management of existing treatments certainly deserves progress, but needs however to be applied rationally, starting from a valid indication to blood sampling, and ending with a sound dosage adaptation decision.

Infections nosocomiales en médecine ambulatoire: importance et prévention [Importance and prevention of nosocomial infections in the outpatient setting]

The concept of nosocomial infections (or healthcare-related infections) applies to the outpatients clinics. However, data are scarce and imprecise in this setting compared with hospitals. The choice of preventive measures is therefore difficult. A lower risk in the outpatient facilities does not justify the complete implementation of hospital precautions. The latter can nevertheless be adapted since infection may be acquired during an ambulatory consultation through the same mechanisms as in hospitals. We propose a preventive strategy derived from standard precautions to be applied in every case, transmission-based precautions that are more rarely needed, and asepsis in case of invasive procedure.

Evaluation de l'espérance de vie chez les personnes agées [Assessment of life expectancy in older people].

Evaluation of the remaining life expectancy in elderly persons plays an important role in their care, most importantly when treatments are associated with severe side effects or when they reduce the quality of life. Prognostic scores, incorporating the functional status in addition to age and comorbidities, enable evaluation of the mortality risk during different periods of time. Despite some limitations, these scores are useful in establishing individualized treatment plans.

Désir de mort, désir de vie et fin de vie [Desire to die, desire to live at the end of life]

Since a couple of years, physicians are confronted with an increasing request of end of life patients asking for a dying facilitated process. The reasons for this are multiple and complex. Existential suffering, increased by depression, a feeling of loss of meaning or dignity and/or being a burden, seems to be a significant factor. Social isolation and physical symptoms seem to be only contributory. The identification of "protecting elements" such as spiritual well-being or a preserved sense of dignity offers new opportunities for care. Providing a space for dialogue by exploring the patient's expectations and fears, his knowledge of care options available at the end of life, his own resources and difficulties frequently contribute to decrease suffering.

Evaluation clinique d'une polyarthrite rhumatoïde en pratique quotidienne [Clinical evaluation of rheumatoid arthritis in practice]

Clinical evaluation is an integral part of medical practice. However, recent data have demonstrated that a systematic and standardized evaluation modifies the prognosis of our rheumatoid arthritis patients. The systematic use of activity indexes allows us to better appreciate the needs of our patients and the necessity to optimize and intensifie treatment. Likewise, auto-evaluations tools bring useful information to patient management.

Santé buccale: déterminants sociaux d'un terrain majeur des inégalités [Oral health: social determinants of a health inequality]

The oral health of disadvantaged social groups is worse at all the ages than that of the favored groups. If tooth decay prevalence decreases, this disease is still unequally distributed: 20% of the children, those with the weakest socio-economic statute (SES), concentrate 60% of the decays. Edentulism strikes significantly more people with weak SES. The inequalities of oral health reflect those of general health. Evidence of the inequalities in oral health is exposed even in the developed countries. Different models of intervention are presented: risk groups identification and targeting by specific programs; oral health community approach which includes socio-economic and public health measures aiming all the population; insurance approach to be combined with the preceding ones.

Approche interdisciplinaire de la decision de don d'organes: l'experience lausannoise [An interdisciplinary approach of the organ donation decision: the Lausanne's experience].

Since 2007, the Interdisciplinary Ethics Platform (Ethos) of the University of Lausanne is leading an interdisciplinary reflection on the organ donation decision. On this basis, the project "Organ transplantation between the rhetoric of the gift and a biomedical view of the body" studies the logics at stake in the organ donation decision-making process. Results highlight many tensions within practices and public discourses in the field of organ donation and transplantation and suggest lines of inquiry for future adjustments.

A new, automated, four-colour interphase FISH approach for the simultaneous detection of specific aneuploidies of diagnostic and prognostic significance in high hyperdiploid ALL

In hyperdiploid acute lymphoblastic leukaemia (ALL), the simultaneous occurrence of specific aneuploidies confers a more favourable outcome than hyperdiploidy alone. Interphase (I) FISH complements conventional cytogenetics (CC) through its sensitivity and ability to detect chromosome aberrations in non-dividing cells. To overcome the limits of manual I-FISH, we developed an automated four-colour I-FISH approach and assessed its ability to detect concurrent aneuploidies in ALL. I-FISH was performed using centromeric probes for chromosomes 4, 6, 10 and 17. Parameters established for automatic nucleus selection and signal detection were evaluated (3 controls). Cut-off values were determined (10 controls, 1000 nuclei/case). Combinations of aneuploidies were considered relevant when each aneuploidy was individually significant. Results obtained in 10 ALL patients (1500 nuclei/patient) were compared with those by CC. Various combinations of aneuploidies were identified. All clones detected by CC were observed by I-FISH. I-FISH revealed numerous additional abnormal clones, ranging between 0.1% and 31.6%, based on the large number of nuclei evaluated. Four-colour automated I-FISH permits the identification of concurrent aneuploidies of prognostic significance in hyperdiploid ALL. Large numbers of cells can be analysed rapidly by this method. Owing to its high sensitivity, the method provides a powerful tool for the detection of small abnormal clones at diagnosis and during follow up. Compared to CC, it generates a more detailed cytogenetic picture, the biological and clinical significance of which merits further evaluation. Once optimised for a given set of probes, the system can be easily adapted for other probe combinations.

Principles of British health visiting

In an international context, it is sometimes helpful to consider how concepts are understood in different countries, and to explore some different roles. Such knowledge rarely transfers directly from one country or place to another, but to hear about developments from elsewhere can spark ideas and thinking that may be helpful for local developments. This paper gives some brief background about how the health visiting profession developed in Great Britain, and then explains the values and principles that underpin its practice today. Some parallels are drawn with the health situation in modern Brazil.

Fécondation in vitro: intérêt et désavantage du remboursement par l'assurance maladie en Suisse [In-vitro fertilization: advantage and disadvantage of covering the costs of IVF/ICSI by the health insurance in Switzerland]

In-vitro fertilization: advantage and disadvantage of covering the costs of IVF/CSI by the health insurance in Switzerland The reimbursement of certain infertility treatments (stimulation with/without insemination) whereas IVF/ICSI is not leads patients with an indication of IVF to prefer treatments of low efficacy. The costs of multiple pregnancies issued by reimbursed or non-reimbursed fertility treatments are paid by the society. There should be measures to reduce these costs and to take the money used today to pay the complications of infertility treatments to reimburse IVF. The efficacy of such a system (single embryo transfer) has been proven in Belgium since several years. The dangers of complete reimbursement (IVF treatment in cases without any chances of success, only because it is for free) can be avoided by an Efficacy and Safety Board.

Colorectal cancer and thoracic surgeons: close encounters of the third kind.

Resection of lung metastases from colorectal cancer (CRC) is increasingly performed with a curative intent. This strategy was made possible in the 1990s by the development of new chemotherapeutic approaches, improved surgical techniques and better imaging modalities. However, evidence-based data showing clinical benefits of lung metastasectomy in this setting are nonexistent, and there are no prospective randomized trials to support the routine performance of these procedures for stage IV CRC. Current evidence suggests that resection of pulmonary metastases in combination with new cytotoxic agents, such as oxaliplatin, irinotecan and bevacizumab, may result in prolonged survival for many, and cure for a small minority of CRC patients who experienced tumor spread beyond the limits of the abdomen. This review focuses on the results of surgical management of CRC patients with lung metastases: we report the outcome of published series according to the presence or the absence of liver metastasis (and hepatic resection) prior to lung resection.

Infection prothétique de hanche à Listeria monocytogenes [Prosthetic hip infection due to Listeria monocytogenes: review of the literature and case report].

With the ageing of the population, articular prosthetic replacements are becoming more and more frequent. One of the most feared complications is prosthetic infection, mostly due to bacteria of the cutaneous flora. Listeria monocytogenes is rarely the cause. This paper describes the management of a hip prosthetic infection due to Listeria monocytogenes. The patient was cured with antimicrobial therapy and a two-stage exchange. This case report creates an opportunity to review the literature in the aim of determining the risk factors and the optimal care.
