Introduction:¦L'incidence annuelle du cancer de l'ovaire en Suisse est de 600 cas, il touche principalement les femmes âgées de plus de 60 ans. Le cancer de l'ovaire est aujourd'hui la 1ère cause de mortalité par cancer gynécologique chez la femme. Le but de notre recherche, est de créer une base de données de toutes les¦patientes atteintes d'un cancer de l'ovaire et hospitalisées au CHUV pour la prise en charge de leur maladie.¦Cette étude rétrospective monocentrique nous permettra en premier lieu d'analyser les caractéristiques de¦cette tumeur présentées par les patientes, les traitements instaurés pour traiter ce cancer et les taux de¦récidives et de survie des patientes en fonction de ces variables.¦Méthodologie:¦Analyse rétrospective de 147 patientes diagnostiquées d'un cancer de l'ovaire et hospitalisées au CHUV entre¦septembre 2001 et mars 2010 pour la prise en charge de leur tumeur ovarienne. Utilisation du programme informatique ARCHIMED qui contient les dossiers médicaux de toutes les patientes inclues dans l'étude et création de 2 bases des données. La 1ère base de données regroupe l'ensemble des patientes de l'étude y¦compris les tumeurs type borderline, la 2ème base de données concerne uniquement les patientes ayant récidivé de leur tumeur. Les tumeurs bénignes ont été exclues de l'étude.¦Résultats:¦La probabilitéde survie à 1 an chez les patientes avec un cancer de l'ovaire, tous stades FIGO et prises en¦charge confondus, hospitalisées au CHUV est de 88,04% (95% CI = 0.7981-‐0.9306), à 3 ans la probabilité de survie est de 70,4% (95% CI = 0.5864-‐0.7936), et à plus de 5 ans, elle est de 60% (95% CI = 0.4315-‐0.6859).¦Nous avons comparé le taux de survie en fonction du stade FIGO de la tumeur ovarienne et nous avons observé une différence significative de survie entre les stades FIGO précoces et les stades avancés (Pvaleur=¦0.0161).¦En plus d'une intervention chirurgicale, les patientes atteintes d'un cancer de l'ovaire sont normalement traitées par une chimiothérapie. Dans notre étude, 70 patientes ont bénéficié d'une chimiothérapie; un¦traitement adjuvant a été donné dans 78 % des cas (N = 55), un traitement néoadjuvant a été administré chez 22% des patientes (N=15). Le type combiné carboplatine-‐taxane est la chimiothérapie la plus fréquente (75%). Au total sur l'étude, 66 patientes sur les 147 (44%) ont récidivé de leur tumeur. En ce qui¦concerne leur prise en charge, 46% des patientes ont reçu une chimiothérapie unique comme du gemzar, cealyx ou taxotère après leur récidive. Une cytoréduction secondaire a également été effectuée chez 33% de ces patientes ayant une récidive. Nous avons également étudié l'intervalle de temps entre la date de la¦récidive et celle du décès. Parmi les 28 patientes décédées chez les récidives, 10 d'entre-‐elles (36%) ont survécu moins d'un an une fois la récidive diagnostiquée, 8 (28%) patientes ont survécu jusqu'à 2 ans, et¦les 10 (36%) autres patientes ont survécu de 2 à 5 ans. En ce qui concerne le taux de mortalité; 39 patientes sur les 147 étudiées sont décédées pendant la période d'observation, soit 26% des cas. La tumeur¦type borderline, présente une prolifération épithéliale atypique sans invasion dans le stroma et représente¦10 à 20% de toutes les tumeurs ovariennes. Dans notre étude, 41 patientes sont porteuses de cette tumeur¦(28%) et la moyenne d'âge est de 49 ans. En ce qui concerne leur prise en charge, l'intervention chirurgicale¦la plus fréquente, soit 23% des cas, est l'annexectomie unilatérale, qui reste une attitude conservative pour¦ces patientes désirant préserver leur fertilité. 6 patientes présentant ce type de tumeur ont récidivé, soit 14% des cas, avec une progression pelvienne, et 3 de ces 6 patientes sont décédées. Dans notre analyse, on observe que la probabilité de vivre plus longtemps que 1an pour les patientes ayant une tumeur borderline est de 93,8% (95% CI= 0.6323-‐ 0.9910), à 3 ans elle est également de 93,8% (95% CI = 0.6323-‐0.9910) et à 5 ans elle est de 78,1% (95% CI = 0.3171-‐0.9483). Nous n'avons pas observé de¦différence de survie dans notre étude entre les patientes présentant une tumeur borderline et le « non‐borderline ». (Pvaleur=0.3301)

BACKGROUND: Rectal and pararectal gastrointestinal stromal tumors (GISTs) are rare. The optimal management strategy for primary localized GISTs remains poorly defined. METHODS: We conducted a retrospective analysis of 41 patients with localized rectal or pararectal GISTs treated between 1991 and 2011 in 13 French Sarcoma Group centers. RESULTS: Of 12 patients who received preoperative imatinib therapy for a median duration of 7 (2-12) months, 8 experienced a partial response, 3 had stable disease, and 1 had a complete response. Thirty and 11 patients underwent function-sparing conservative surgery and abdominoperineal resection, respectively. Tumor resections were mostly R0 and R1 in 35 patients. Tumor rupture occurred in 12 patients. Eleven patients received postoperative imatinib with a median follow-up of 59 (2.4-186) months. The median time to disease relapse was 36 (9.8-62) months. The 5-year overall survival rate was 86.5%. Twenty patients developed local recurrence after surgery alone, two developed recurrence after resection combined with preoperative and/or postoperative imatinib, and eight developed metastases. In univariate analysis, the mitotic index (≤5) and tumor size (≤5 cm) were associated with a significantly decreased risk of local relapse. Perioperative imatinib was associated with a significantly reduced risk of overall relapse and local relapse. CONCLUSIONS: Perioperative imatinib therapy was associated with improved disease-free survival. Preoperative imatinib was effective. Tumor shrinkage has a clear benefit for local excision in terms of feasibility and function preservation. Given the complexity of rectal GISTs, referral of patients with this rare disease to expert centers to undergo a multidisciplinary approach is recommended.

OBJECTIVE: To provide an update to the original Surviving Sepsis Campaign clinical management guidelines, "Surviving Sepsis Campaign Guidelines for Management of Severe Sepsis and Septic Shock," published in 2004. DESIGN: Modified Delphi method with a consensus conference of 55 international experts, several subsequent meetings of subgroups and key individuals, teleconferences, and electronic-based discussion among subgroups and among the entire committee. This process was conducted independently of any industry funding. METHODS: We used the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) system to guide assessment of quality of evidence from high (A) to very low (D) and to determine the strength of recommendations. A strong recommendation (1) indicates that an intervention's desirable effects clearly outweigh its undesirable effects (risk, burden, cost) or clearly do not. Weak recommendations (2) indicate that the tradeoff between desirable and undesirable effects is less clear. The grade of strong or weak is considered of greater clinical importance than a difference in letter level of quality of evidence. In areas without complete agreement, a formal process of resolution was developed and applied. Recommendations are grouped into those directly targeting severe sepsis, recommendations targeting general care of the critically ill patient that are considered high priority in severe sepsis, and pediatric considerations. RESULTS: Key recommendations, listed by category, include early goal-directed resuscitation of the septic patient during the first 6 hrs after recognition (1C); blood cultures before antibiotic therapy (1C); imaging studies performed promptly to confirm potential source of infection (1C); administration of broad-spectrum antibiotic therapy within 1 hr of diagnosis of septic shock (1B) and severe sepsis without septic shock (1D); reassessment of antibiotic therapy with microbiology and clinical data to narrow coverage, when appropriate (1C); a usual 7-10 days of antibiotic therapy guided by clinical response (1D); source control with attention to the balance of risks and benefits of the chosen method (1C); administration of either crystalloid or colloid fluid resuscitation (1B); fluid challenge to restore mean circulating filling pressure (1C); reduction in rate of fluid administration with rising filing pressures and no improvement in tissue perfusion (1D); vasopressor preference for norepinephrine or dopamine to maintain an initial target of mean arterial pressure > or = 65 mm Hg (1C); dobutamine inotropic therapy when cardiac output remains low despite fluid resuscitation and combined inotropic/vasopressor therapy (1C); stress-dose steroid therapy given only in septic shock after blood pressure is identified to be poorly responsive to fluid and vasopressor therapy (2C); recombinant activated protein C in patients with severe sepsis and clinical assessment of high risk for death (2B except 2C for postoperative patients). In the absence of tissue hypoperfusion, coronary artery disease, or acute hemorrhage, target a hemoglobin of 7-9 g/dL (1B); a low tidal volume (1B) and limitation of inspiratory plateau pressure strategy (1C) for acute lung injury (ALI)/acute respiratory distress syndrome (ARDS); application of at least a minimal amount of positive end-expiratory pressure in acute lung injury (1C); head of bed elevation in mechanically ventilated patients unless contraindicated (1B); avoiding routine use of pulmonary artery catheters in ALI/ARDS (1A); to decrease days of mechanical ventilation and ICU length of stay, a conservative fluid strategy for patients with established ALI/ARDS who are not in shock (1C); protocols for weaning and sedation/analgesia (1B); using either intermittent bolus sedation or continuous infusion sedation with daily interruptions or lightening (1B); avoidance of neuromuscular blockers, if at all possible (1B); institution of glycemic control (1B), targeting a blood glucose < 150 mg/dL after initial stabilization (2C); equivalency of continuous veno-veno hemofiltration or intermittent hemodialysis (2B); prophylaxis for deep vein thrombosis (1A); use of stress ulcer prophylaxis to prevent upper gastrointestinal bleeding using H2 blockers (1A) or proton pump inhibitors (1B); and consideration of limitation of support where appropriate (1D). Recommendations specific to pediatric severe sepsis include greater use of physical examination therapeutic end points (2C); dopamine as the first drug of choice for hypotension (2C); steroids only in children with suspected or proven adrenal insufficiency (2C); and a recommendation against the use of recombinant activated protein C in children (1B). CONCLUSIONS: There was strong agreement among a large cohort of international experts regarding many level 1 recommendations for the best current care of patients with severe sepsis. Evidenced-based recommendations regarding the acute management of sepsis and septic shock are the first step toward improved outcomes for this important group of critically ill patients.

OBJECTIVE: This study was designed to analyze the duration of chest tube drainage on pain intensity and distribution after cardiac surgery. METHODS: Two groups of 80 cardiac surgery adult patients, operated on in two different hospitals, by the same group of cardiac surgeons, and with similar postoperative strategies, were compared. However, in one hospital (long drainage group), a conservative policy was adopted with the removal the chest tubes by postoperative day (POD) 2 or 3, while in the second hospital (short drainage group), all the drains were usually removed on POD 1. RESULTS: There was a trend toward less pain in the short drainage group, with a statistically significant difference on POD 2 (P=0.047). There were less patients without pain on POD 3 in the long drainage group (P=0. 01). The areas corresponding to the tract of the pleural tube, namely the epigastric area, the left basis of the thorax, and the left shoulder were more often involved in the long drainage group. There were three pneumonias in each group and no patient required repeated drainage. CONCLUSIONS: A policy of early chest drain ablation limits pain sensation and simplifies nursing care, without increasing the need for repeated pleural puncture. Therefore, a policy of short drainage after cardiac surgery should be recommended.

PRINCIPLES: Interstitial pregnancy represents 2% of ectopic pregnancies, but it is a highly morbid condition with a 2.5% of maternal mortality. Its diagnostic and therapeutic management remains controversial. The aim of this review is to describe the management of interstitial pregnancy in our institution between 2001 and 2011 and to define some general rules for the clinical practice. METHODS: Single institution retrospective study. RESULTS: Eleven women were treated for interstitial pregnancy. The median age was 33 years and the median gestity was 4. Seven patients had a history of gynaecological surgery and four interstitial pregnancies followed in vitro fertilisation. The diagnosis was made at a median gestational age of seven weeks with a median beta-HCG level of 5,838 U/l. Six of the eleven patients received an initial treatment with intracornual methotrexate, three with intramuscular methotrexate and two with surgery. The median time to beta-HCG resolution was 58 days. Three of the eleven patients needed a second line treatment: two after intramuscular methotrexate and one after intracornual methotrexate. Six patients had further pregnancies and delivered by caesarean section. CONCLUSIONS: A high prevalence of previous ectopic pregnancies, gynaecological surgery and of pregnancies resulting from in vitro fertilisation was observed. The earliness of the diagnosis was the factor that allowed a conservative treatment in most cases. Beta-HCG level follow up was fundamental in allowing a second line therapy but beta-HCG can persist over a long period of time and this must be taken into account due to its possible psychological impact. Intracornual methotrexate seems to be more efficacious than intramuscular methotrexate in our series.

Transitional-cell carcinoma of the renal pelvis or ureter is a relatively rare disease. Several risk factors are smoking, occupational carcinogens, analgesic abuse or Balkan nephropathy. The grade and stage of the disease have the most significant impact on the outcome. The treatment of renal pelvis and ureter tumours is open or laparoscopic surgery varying from conservative to more extensive surgical procedures, i.e. radical nephroureterectomy including removal of the contents of Gerota's fascia with ipsilateral ureter and a cuff of bladder at its distal extent. Most available data are from retrospective studies and surgery is the mainstay of treatment. Chemotherapy and/or radiation therapy are possible adjuvant or primary treatment for selected patients; however, prospective studies are needed to confirm their use.
