Scores de mesure fonctionnelle articulaire pour le praticien [Joint functional outcome score for the clinician].

The sports clinician faces multiple treatment options when dealing with overload injuries, and it is important to evaluate their outcomes. Multiple scores exist, some clincian rated (CRO), others patient rated (PRO), the latter being currently favoured. This review presents some of these scores and we selected the ones we feel are the most appropriate for a sports clinician. We considered these common problems: tennis elbow, rotator cuff issues, groin pain, patellofemoral pain syndrome, achilles tendinopathy and ankle instability. In addition, an activity level score is useful to weigh the result in the context of return to performance. These scores help to create a common language between therapists and to evaluate treatments objectively.

Successful therapy for a patient with an infected ascending aortic graft and sternal osteomyelitis without graft removal.

Objective: Following open-heart surgery, sternal osteomyelitis or infection of the graft may be a serious complication with high mortality rates. The recommended treatment of an infected graft is its explantation. Because of the poor performance status of the patient, this may not always be an option. We report a successful treatment concept without removal of the infected graft. Methods: The infected ascending aortic graft and the remaining sternum of a critically ill 60-year-old man were covered with a bilateral pectoralis muscle flap. Results: Postoperatively, the laboratory test values normalized and the patient was discharged 1 month after the intervention. One year after surgery, the patient was in good condition and the examination showed no signs of infection. Conclusion: The thus demonstrated treatment concept with insertion of well-vascularized tissues in combination with a specific antibiotic regime in our hands proved to be an additional option for the successful management of life-threatening infections of a sternal osteomyelitis in combination of an infected aortic graft.

Suivi prospectif à une année des prothèses de genou F.I.R.S.T. Evolution avec analyse ambulatoire de la marche

Le but de mon travail de master est de présenter les résultats à une année postopératoire d'une étude prospective sur une nouvelle prothèse totale du genou : la F.I.R.S.T. Evolution. Cette prothèse s'intéresse à des patients plus jeunes, avec une importante laxité des ligaments collatéraux. L'étude finale suivra à cinq ans une cohorte de cinquante patients environ. Actuellement, nous suivons 17 patients opérés avec cette prothèse (dont 9 femmes et 8 hommes, 9 genoux droits et 8 genoux gauches) avec un âge moyen de 69,10 ans (de 42 à 83 ans). Pour l'obtention des résultats, les patients ont remplis des questionnaires spécifiques couramment utilisés (Eq5D, WOMAC, KSS, échelle analogique de la douleur EVA/VAS, UCLA activity-rating level), ont bénéficié de contrôles radiologiques réguliers et d'une analyse régulière de la marche, à trois vitesses différentes. Cette analyse est objective et se base sur un système de capteurs miniaturisés. Les résultats cliniques obtenus à une année démontrent une amélioration globale de la fonction du genou et de la qualité de vie perçue par le patient (Eq5D, WOMAC, EVA/VAS, KSS, UCLA). Les données à une année de l'analyse de marche montrent une amélioration significative dans tous les paramètres du cycle de marche et aux différentes vitesses. En comparant nos résultats avec ceux précédemment obtenus, nous pouvons être satisfaits car ils se sont améliorés depuis la dernière échéance à 6 mois. De plus, nos résultats à une année suivent ceux obtenus dans d'autres études utilisant les mêmes questionnaires et une analyse objective de la marche. On s'attend à ce que ces données se stabilisent voire continuent de s'améliorer dans les années à venir.

Chest pain and ST-segment elevation in a patient with Duchenne muscular dystrophy, what really happened?

Introduction: Myocardial infarction is rare in children, if it occurs, findings are almost similar to adults. In Ouchenne muscular dystrophy (OMO), ST segment displacement associated with typical chest pain can occur. We report the case of a young boy with OMO presenting symptoms suggestive of myocardial ischemia. Case report: 7 year old boy, diagnosed with OMO, eoming to the emergency department with complaints of acute chest pain, dyspnoea and anxiety the night before. Clinical examination was not remarkable, with exception of findings of the OMO. ECG showed important ST-segment elevation in right precordial leads. Major increase in troponin 1 42.33 mcg/(normal, <0.04 mcg/I) was found. Echocardiography revealed slight yskinesia of postero-septal wall without decrease in ventricular function. As acute pain had happened more han 12 hours before referral and as the child was asymptomatic, he received anti-platelets therapy. The serum level of troponin 1 declined and the ECG normalised in a few days. Cardiac catheterization did not show any coronary anomaly or eardiac dysfunction. Cardiac biopsy revealed myocardial cell damaged compatible with OMO cardiomyopathy. Tc99m myocardial single-photon emission computed tomography (SPECT) did not show any radionuclide uptake defect. Conclusions: ln this particular context of children with OMO, the classical signs of myocardial ischemia could be misleading, standard investigation failed to demonstrate the cause of chest pain and inerease of troponin l, there was also no evidence of myocarditis. Role of late enhancement (LE) signal in eontrast-enhanced MRI in the understanding of the occurring process has to be evaluated.

Impact of an intervention to control risk associated with patient transfer.

QUESTION UNDER STUDY: Hospitals transferring patients retain responsibility until admission to the new health care facility. We define safe transfer conditions, based on appropriate risk assessment, and evaluate the impact of this strategy as implemented at our institution. METHODS: An algorithm defining transfer categories according to destination, equipment monitoring, and medication was developed and tested prospectively over 6 months. Conformity with algorithm criteria was assessed for every transfer and transfer category. After introduction of a transfer coordination centre with transfer nurses, the algorithm was implemented and the same survey was carried out over 1 year. RESULTS: Over the whole study period, the number of transfers increased by 40%, chiefly by ambulance from the emergency department to other hospitals and private clinics. Transfers to rehabilitation centres and nursing homes were reassigned to conventional vehicles. The percentage of patients requiring equipment during transfer, such as an intravenous line, decreased from 34% to 15%, while oxygen or i.v. drug requirement remained stable. The percentage of transfers considered below theoretical safety decreased from 6% to 4%, while 20% of transfers were considered safer than necessary. A substantial number of planned transfers could be "downgraded" by mutual agreement to a lower degree of supervision, and the system was stable on a short-term basis. CONCLUSION: A coordinated transfer system based on an algorithm determining transfer categories, developed on the basis of simple but valid medical and nursing criteria, reduced unnecessary ambulance transfers and treatment during transfer, and increased adequate supervision.

Neurally adjusted ventilatory assist (NAVA) improves patient-ventilator interaction during non-invasive ventilation delivered by face mask.

PURPOSE: To determine if, compared to pressure support (PS), neurally adjusted ventilatory assist (NAVA) reduces patient-ventilator asynchrony in intensive care patients undergoing noninvasive ventilation with an oronasal face mask. METHODS: In this prospective interventional study we compared patient-ventilator synchrony between PS (with ventilator settings determined by the clinician) and NAVA (with the level set so as to obtain the same maximal airway pressure as in PS). Two 20-min recordings of airway pressure, flow and electrical activity of the diaphragm during PS and NAVA were acquired in a randomized order. Trigger delay (T(d)), the patient's neural inspiratory time (T(in)), ventilator pressurization duration (T(iv)), inspiratory time in excess (T(iex)), number of asynchrony events per minute and asynchrony index (AI) were determined. RESULTS: The study included 13 patients, six with COPD, and two with mixed pulmonary disease. T(d) was reduced with NAVA: median 35 ms (IQR 31-53 ms) versus 181 ms (122-208 ms); p = 0.0002. NAVA reduced both premature and delayed cyclings in the majority of patients, but not the median T(iex) value. The total number of asynchrony events tended to be reduced with NAVA: 1.0 events/min (0.5-3.1 events/min) versus 4.4 events/min (0.9-12.1 events/min); p = 0.08. AI was lower with NAVA: 4.9 % (2.5-10.5 %) versus 15.8 % (5.5-49.6 %); p = 0.03. During NAVA, there were no ineffective efforts, or late or premature cyclings. PaO(2) and PaCO(2) were not different between ventilatory modes. CONCLUSION: Compared to PS, NAVA improved patient ventilator synchrony during noninvasive ventilation by reducing T(d) and AI. Moreover, with NAVA, ineffective efforts, and late and premature cyclings were absent.

Early occurrence of lung adenocarcinoma and breast cancer after radiotherapy of a chest wall sarcoma in a patient with a de novo germline mutation in TP53.

We report a 26-year-old female patient who was diagnosed within 4 years with chest sarcoma, lung adenocarcinoma, and breast cancer. While her family history was unremarkable, DNA sequencing of TP53 revealed a germline de novo non-sense mutation in exon 6 p.Arg213X. One year later, she further developed a contralateral ductal carcinoma in situ, and 18 months later a jaw osteosarcoma. This case illustrates the therapeutic pitfalls in the care of a young cancer patient with TP53 de novo germline mutations and the complications related to her first-line therapy. Suggestion is made to use the less stringent Chompret criteria for germline TP53 mutation screening. Our observation underlines the possibly negative effect of radiotherapy in generating second tumors in patients with a TP53 mutation. We also present a review of six previously reported cases, comparing their cancer phenotypes with those generally produced by TP53 mutations.

Methadone maintenance treatment (MMT) in general practice or in specialized centers: profile of patients in the Swiss Canton of Vaud.

We studied profile of patients (n=1782) treated in specialized centers and general practice (GP) enrolled in methadone maintenance treatment (MMT) programs during 2001 in the Swiss Canton of Vaud. We found that GPs treated the majority of patients (76%). Specialized centers treated a higher proportion of patients with uncontrolled intravenous use of cocaine and heroin, and prescribed neuroleptics as concomitant medication three times more frequently than GPs. Patients treated in specialized centers were more likely to undergo screening for HIV, HBV, HCV, and receive complete HBV immunization. In conclusion, specialized centers are more likely to treat severely addicted patients and patients with a poor global assessment (physical, psychiatric, and social).

Comparison of the clientele of an anonymous HIV test centre and persons tested in the general population.

This study compares the clientele of a Swiss anonymous test centre with the general population tested. Information was obtained through similar questionnaires submitted to two samples of HIV-tested people aged from 17 to 45 years: the first administered in the context of a general population telephone survey (n = 245) and the second completed during face-to-face interviews of the clientele of an anonymous test centre (n = 250). The test centre sample has higher proportions of younger and single people. Attenders for anonymous testing were more likely to have acquired a new regular partner during the year preceding the interview (48.0% versus 14.4%). These differences remain when controlling for age and gender. Decision to test comes mostly from the respondent's own initiative, but suggestion from a doctor is more frequent in the general population (23.8% versus 0.8%), whereas suggestion from partner or friends is more frequent in the anonymous centre (44.4% versus 3.0%). The anonymous test centre clientele is not different from the general population tested except for the relational situation and origin of decision for testing. The test centre has become a place where the general population finds a response to a situation-specific need for HIV testing.

Le syndrome hépatorénal chez le patient cirrhotique [Hepatorenal syndrome in patients with liver cirrhosis].

Hepatorenal syndrome is a particular form of functional renal failure which may develop in patients with liver cirrhosis. On a clinical standpoint, precise diagnostic criteria have been established to clearly define this entity, whereas recent advances in the understanding of the biology of vasoactive mediators and the physiology of microcirculation have allowed to better anticipate its pathophysiological mechanisms. During the course of cirrhosis, sinusoidal portal hypertension leads to splanchnic and systemic vasodilation, responsible for a reduction of effective arterial blood volume. As a result, a state of intense renal vasoconstriction develops, leading to renal failure in the absence of any organic renal disease. At this stage, liver transplantation is the only definitive therapy able to reverse renal dysfunction. In recent years, innovative therapies have shown promise to prolong survival in patients with hepatorenal syndrome, including the administration of analogs of vasopressin (mainly terlipressin), the insertion of transjugular intrahepatic portosystemic shunts and the use of novel techniques of dialysis. On a preventive viewpoint, several simple measures have been shown to reduce the risk of hepatorenal syndrome in cirrhotic patients, including the appropriate use of diuretics, the avoidance of nephrotoxic drugs, the prophylaxis of spontaneous bacterial peritonitis and optimal fluid management in patients undergoing large volume paracentesis.

Mutation screening of patients with Alzheimer disease identifies APP locus duplication in a Swedish patient.

BACKGROUND: Missense mutations in three different genes encoding amyloid-β precursor protein, presenilin 1 and presenilin 2 are recognized to cause familial early-onset Alzheimer disease. Also duplications of the amyloid precursor protein gene have been shown to cause the disease. At the Dept. of Geriatric Medicine, Karolinska University Hospital, Sweden, patients are referred for mutation screening for the identification of nucleotide variations and for determining copy-number of the APP locus. METHODS: We combined the method of microsatellite marker genotyping with a quantitative real-time PCR analysis to detect duplications in patients with Alzheimer disease. RESULTS: In 22 DNA samples from individuals diagnosed with clinical Alzheimer disease, we identified one patient carrying a duplication on chromosome 21 which included the APP locus. Further mapping of the chromosomal region by array-comparative genome hybridization showed that the duplication spanned a maximal region of 1.09 Mb. CONCLUSIONS: This is the first report of an APP duplication in a Swedish Alzheimer patient and describes the use of quantitative real-time PCR as a tool for determining copy-number of the APP locus.

Efavirenz in an obese HIV-infected patient - a report and an in vitro-in vivo extrapolation model indicate risk of underdosing.

Here, we report suboptimal efavirenz exposure in an obese patient treated with the standard 600 mg dose. Tripling the dose allowed attainment of therapeutic efavirenz concentrations. We developed an in vitro-in vivo extrapolation model to quantify dose requirements in obese individuals. Obesity represents a risk factor for antiretroviral therapy underdosing.

Liver Transplantation for Neuroendocrine Tumors in Europe-Results and Trends in Patient Selection: A 213-Case European Liver Transplant Registry Study.

OBJECTIVE:: The purpose of this study was to assess outcomes and indications in a large cohort of patients who underwent liver transplantation (LT) for liver metastases (LM) from neuroendocrine tumors (NET) over a 27-year period. BACKGROUND:: LT for NET remains controversial due to the absence of clear selection criteria and the scarcity and heterogeneity of reported cases. METHODS:: This retrospective multicentric study included 213 patients who underwent LT for NET performed in 35 centers in 11 European countries between 1982 and 2009. One hundred seven patients underwent transplantation before 2000 and 106 after 2000. Mean age at the time of LT was 46 years. Half of the patients presented hormone secretion and 55% had hepatomegaly. Before LT, 83% of patients had undergone surgical treatment of the primary tumor and/or LM and 76% had received chemotherapy. The median interval between diagnosis of LM and LT was 25 months (range, 1-149 months). In addition to LT, 24 patients underwent major resection procedures and 30 patients underwent minor resection procedures. RESULTS:: Three-month postoperative mortality was 10%. At 5 years after LT, overall survival (OS) was 52% and disease-free survival was 30%. At 5 years from diagnosis of LM, OS was 73%. Multivariate analysis identified 3 predictors of poor outcome, that is, major resection in addition to LT, poor tumor differentiation, and hepatomegaly. Since 2000, 5-year OS has increased to 59% in relation with fewer patients presenting poor prognostic factors. Multivariate analysis of the 106 cases treated since 2000 identified the following predictors of poor outcome: hepatomegaly, age more than 45 years, and any amount of resection concurrent with LT. CONCLUSIONS:: LT is an effective treatment of unresectable LM from NET. Patient selection based on the aforementioned predictors can achieve a 5-year OS between 60% and 80%. However, use of overly restrictive criteria may deny LT to some patients who could benefit. Optimal timing for LT in patients with stable versus progressive disease remains unclear.
