Imaging of the kidney relies on three main imaging modalities: ultrasound, CT scan and MRI, on one hand, and scintigraphy, on the other hand. First intent ultrasound provides anatomic/vascular and functional information. Tissue perfusion assessment using ultrasound can be improved using contrast agents. Renal ultrasound is particularly useful but remains operator and tumor/patient-dependent (obese, ectopic kidney, type and site of tumor). It is cheap and does not irradiate. Ultrasound contrast agents can improve the sensitivity of ultrasound in many clinical situations. Intravenous urography has been replaced by CT scan. Multi-slice CT scan is indeed the main renal imaging modality: it allows for angiographic and urographic explorations. MRI provides anatomic and functional information. Renal failure must be looked for before performing CT scan or MRI so as to avoid iatrogenic complications. Severe renal failure is a contraindication to both. Each imaging modality has pros and cons and specific indications. CT scan is the mainstay of renal imaging provided that standardized injection protocols are used, that the dose is limited (low-dose protocol) and renal function is assessed. Dynamic renal scintigraphy can be used in situations where information on the function of each kidney is necessary. ©John Libbey Eurotext. Source

The advent of targeted therapies in the treatment of renal cancer has shown different types of lesions of the oral cavity, which appear to be specific to the drug classes used (mTOR inhibitors, anti-angiogenic agents and conventional cytotoxic drugs). Before starting treatment with targeted therapy, it is essential to have an oral and a dental examination. The treatment of mucositis induced by targeted therapies is based on bicarbonate-based mouthwash, with the optional addition of an antifungal or a local antiseptic. It is possible to use topical or systemic analgesics for the pain. Dietary advice for patients is also useful. Most cases of epistaxis caused by anti-angiogenics stop spontaneously and require no medical intervention. Regular application of an emollient can be used to prevent the formation of scabs. ©John Libbey Eurotext. Source

Purpose To conduct a cross-cultural adaptation of the Core Outcome Measures Index (COMI) into French according to established guidelines. Methods Seventy outpatients with chronic low back pain were recruited from six spine centres in Switzerland and France. They completed the newly translated COMI, and the Roland Morris disability (RMQ), Dallas Pain (DPQ), adjectival pain rating scale, WHO Quality of Life, and EuroQoL-5D questionnaires. After ∼14 days RMQ and COMI were completed again to assess reproducibility; a transition question (7-point Likert scale; ''very much worse'' through ''no change'' to ''very much better'') indicated any change in status since the first questionnaire. Results COMI whole scores displayed no floor effects and just 1.5% ceiling effects. The scores for the individual COMI items correlated with their corresponding full-length reference questionnaire with varying strengths of correlation (0.33-0.84, P<0.05). COMI whole scores showed a very good correlation with the ''multidimensional'' DPQ global score (Rho = 0.71). 55 patients (79%) returned a second questionnaire with no/minimal change in their back status. The reproducibility of individual COMI 5-point items was good, with test-retest differences within one grade ranging from 89% for 'social/work disability' to 98% for 'symptom-specific well-being'. The intraclass correlation coefficient for the COMI whole score was 0.85 (95% CI 0.76-0.91). Conclusions In conclusion, the French version of this short, multidimensional questionnaire showed good psychometric properties, comparable to those reported for German and Spanish versions. The French COMI represents a valuable tool for future multicentre clinical studies and surgical registries (e.g. SSE Spine Tango) in French-speaking countries. © 2011 Springer-Verlag. Source

Introduction. - Niemann-Pick type C disease (NPC) is a rare genetic disease with an extremely heterogeneous clinical presentation. The adult form of this disease is usually expressed with neurological symptoms; however, non-specific psychiatric disorders are often associated. This article presents a retrospective study on a cohort of NPC patients diagnosed in France with the objectives of researching the presence of psychiatric disorders and qualifying these disorders. Methods. - After carrying out a research within hospital records, a questionnaire was sent to patients or their relatives and their doctors. Results. - The cohort was made up of 22 patients. Fifty-two questionnaires were sent to 47 different doctors. We received 67% of answers from the doctors, with 42% of positive answers. The answer rate of the families was 27%. Among the 22 patients, we found the presence of psychiatric disorders in 86% of cases. Seventy-three percent of the patients presented behavior disorders. Among them, 27% exhibited psychomotor excitation or agitation, 23% aggressiveness, 18% intolerance to frustration, 27% sleep disorders and 23% apathy, listlessness and/or clinophilia. Fifty-five percent of patients presented psychotic symptoms, with 45% with delusions and 36% with hallucinations. Seventy-seven percent of patients presented with mood disorders: 36% suffered from depression and 27% from emotional lability or mood swings. Of the 22 patients, a diagnosis of psychiatric disease was made in 50% of cases. The main diagnoses were schizophrenia (27%) and depression (23%). The other diagnoses identified were acute delirium, dysthymia, infantile psychosis, intellectual disharmonic disability and personality disorder. The average age of emergence of the troubles was 17.1 years old for neurological symptoms and 20.9 years old for psychiatric symptoms. The median age was 18 years old for neurological symptoms and 20 years old for psychiatric ones. In 45% of cases, psychiatric occurred after neurological symptoms; in 27%, they occurred before and they were concomitant in 9%. In 50% of cases, psychiatric symptoms existed before the early diagnosis of NPC; in 9%, they occurred after and in 5%, they occurred during the diagnostic process. Fifty-five percent of the patients were followed by a psychiatrist, 50% of patients had been hospitalized at least once in a psychiatric department. Fifty-five percent of the patients received neuroleptics or antipsychotics, 41% received antidepressants, 41% received mood stabilizers or anticonvulsants, 45% received anxiolytics and 23% hypnotics. Discussion. - Whilst a small cohort, the low incidence of NPC (1/120,000 to 1/150,000) and the scale of a single-center study make the findings important. In our cohort, we found psychiatric disorders in most of the patients. The symptoms were varied and non-specific, and mainly found in late-onset forms of the disease. This incidence of disorder is much higher than the literature suggests, generally describing psychiatric disorders in approximately one third of NPC adult form. On the other hand, our results on schizophrenia are consistent with the updated recommendations for the diagnosis and management of NPC. According to our results, a retrospective study to develop a suspicion index to aid diagnosis of NPC suggests that psychotic symptoms are underestimated in this disease. In our cohort, we also found a significant rate of psychiatric hospitalizations and psychotropic drugs prescription that had not been previously described in the international literature. We did not have sufficient data on the effectiveness of symptomatic treatment in NPC; the literature was contradictory. It should be noted that despite the high rate of psychiatric patients in our cohort, only half of patients consulted a psychiatrist and a few of them have regular follow-up. To conclude, our study is in line with the current literature that suggests an under-estimation of psychiatric disorders in NPC, but also a likely under-diagnosis of NPC in psychiatric departments. All this data encourage us to keep alerting psychiatrists to identifying this disease in order to promote early and optimal care. © 2016 L'Encéphale, Paris. Source

Purpose: The Core Outcome Measure Index (COMI) is a multidimensional questionnaire that investigates five dimensions in low back pain (LBP) patients, but does not address the psychological dimension. As the biopsychosocial perspective is recognized as important to capture the entire clinical picture of these patients, this multicenter prospective cohort study was designed to investigate the psychometric properties of a modified version of the COMI (COMIAD) which included 2 additional items, exploring anxiety and depression, respectively. Methods: 168 subacute or chronic LBP patients recruited in spine clinics completed a set of questionnaires before and after treatment (follow-up at 6 months). Construct validity was explored by comparing each item of the COMIAD to validated full-length questionnaires. Thus two additional questionnaires were included to assess the construct validity of the anxiety and depression measures. The psychometric properties of the COMI and COMIAD were then compared. Results: The two new items showed good internal consistency, high correlations with the corresponding full-length questionnaires, no floor or ceiling effect and good reproducibility (test–retest agreement kappa 0.68 for anxiety, 0.62 for depression). The addition of the 2 items did not alter internal validity (Cronbach’s alpha = 0.88 and 0.87, respectively). The smallest detectable difference, the Minimal Clinically Important Improvement and the Patient Acceptable Symptom State were only minimally affected by the changes. Conclusion: The questions exploring anxiety and depression have good intrinsic and psychometric capacities (i.e., no floor or ceiling effects and high correlations with full-length scales) and did not significantly modify the psychometrics of the original COMI questionnaire. The COMIAD offers the possibility to include the psychological dimension in the multidimensional evaluation without significantly affecting questionnaire length. © 2015, Springer-Verlag Berlin Heidelberg.
