Functional multidisciplinary rehabilitation versus outpatient physiotherapy for non specific low back pain: randomized controlled trial.

INTRODUCTION: In recent decades the treatment of non-specific low back pain has turned to active modalities, some of which were based on cognitive-behavioural principles. Non-randomised studies clearly favour functional multidisciplinary rehabilitation over outpatient physiotherapy. However, systematic reviews and meta-analysis provide contradictory evidence regarding the effects on return to work and functional status. The aim of the present randomised study was to compare long-term functional and work status after 3-week functional multidisciplinary rehabilitation or 18 supervised outpatient physiotherapy sessions. METHODS: 109 patients with non-specific low back pain were randomised to either a 3-week functional multidisciplinary rehabilitation programme, including physical and ergonomic training, psychological pain management, back school and information, or 18 sessions of active outpatient physiotherapy over 9 weeks. Primary outcomes were functional disability (Oswestry) and work status. Secondary outcomes were lifting capacity (Spinal Function Sort and PILE test), lumbar range-of-motion (modified-modified Schöber and fingertip-to-floor tests), trunk muscle endurance (Shirado and Biering-Sörensen tests) and aerobic capacity (modified Bruce test). RESULTS: Oswestry disability index was improved to a significantly greater extent after functional multidisciplinary rehabilitation compared to outpatient physiotherapy at follow-up of 9 weeks (P = 0.012), 9 months (P = 0.023) and 12 months (P = 0.011). Work status was significantly improved after functional multidisciplinary rehabilitation only (P = 0.012), resulting in a significant difference compared to outpatient physiotherapy at 12 months' follow-up (P = 0.012). Secondary outcome results were more contrasted. CONCLUSIONS: Functional multidisciplinary rehabilitation was better than outpatient physiotherapy in improving functional and work status. From an economic point of view, these results should be backed up by a cost-effectiveness study.

Alexithymia in patients recently diagnosed with cancer

Background: Contrary to the frequent assumption that alexithymia is a rather static personality trait hampering psychotherapeutic approaches, we have observed that cancer patients who qualify for the criteria of alexithymia may benefit from psychotherapy. Therefore, in patients facing a cancer diagnosis, alexithymia can often be considered as a state due to the threat of the disease (secondary alexithymia).Aims: To identify prevalence of alexithymia in newly diagnosed cancer patients and to document its evolution with and without psychotherapeutic interventions.Methods: Between 2006 and summer 2009, every newpatient of the Oncology Service of the University Hospital Lausanne was invited to benefit from psychotherapeutic support. Accepting patients were randomly assigned to a psychotherapeutic intervention or to a 4-month waiting list. Psychotherapies were formalized as psychodynamic-oriented short interventions (1-4 sessions) or brief psychodynamic psychotherapies (16 sessions). Patients who declined psychotherapeutic support were asked to participate in an observational group. Socio-demographic and medical data, alexithymia (TAS), anxiety and depression (SCL-90, HADS) and quality of life (EORTC) of participants of all groups were recorded at base line and at 1, 4, 8 and 12-months follow-up. Results: Of the 419 patients included, 190 desired psychotherapeutic support (94 were assigned to an immediate and 96 to a delayed intervention) and 229 patients accepted to be followed in the observational group. A very high proportion, almost 2/3 of the patients in all groups, qualified for alexithymia. With regard to the evolution of alexithymia, no significant changes were observed within and between groups and psychological symptoms also remained almost stable.Conclusions: Secondary alexithymia seems to be highly prevalent in newly diagnosed cancer patients. This raises important clinical and scientific questions: are these patients deprived from psychological support? How should interventions be conceptualized? Are interventions necessary and beneficial? Does alexithymia neutralize the effect of interventions on symptoms of anxiety and depression? Which outcome should be chosen for patients with secondary alexithymia?Keywords: Alexithymia, cancer, psycho-oncology, psychotherapy, secondary alexithymia

Psychodynamic psychotherapy in newly diagnosed cancer patients: a randomized controlled trial

Background and aims: More than 30% of cancer patients develop a psychiatric disorder during the evolution of their disease. While evidence exists, that psychotherapy can improve psychological distress, questions, such as the prevalence of patients accepting psychotherapy, treatment indications and effectiveness of psychotherapeutic interventions in the oncology setting remain unanswered. The aims were: (1) To assess the prevalence of newly diagnosed cancer patients motivated to engage in psychotherapeutic interventions; (2) to identify those who benefit; and (3) to evaluate their effectiveness. Methods: Every new patient of the Oncology Service at the University Hospital Lausanne was informed of the possibility of benefitting from psychotherapeutic support. Patients who accepted were randomly assigned to individual psychotherapy or to a 4-month waiting list. Psychotherapies were formalized as psychodynamicoriented short interventions (1-4 sessions) or brief psychodynamic psychotherapies (16 sessions). Patients who refused psychotherapy were asked to participate in an observational group. Socio-demographic and medical data, anxiety, depression, alexithymia and quality of life (SCL- 90, HADS, TAS, EORTC) of all participants were evaluated at base line and at 1, 4, 8 and 12 -months Follow- Up. Results: So far 1047 patients have been approached, 20% were included in the study (intervention n=68, observation n=122), 32% were excluded, 22% could not be contacted and 26% refused to participate. At baseline, patients who accepted psychotherapeutic support showed higher depression and anxiety scores (HADS, SCL-90) compared to controls. 56% benefited from 4 sessions of psychological support, 44% engaged in 16 sessions of brief psychodynamic therapy. Conclusions: The preliminary results of this ongoing trial suggest that a minority of newly cancer patients accept psychotherapeutic intervention. These patients are more depressed than controls. Their motivation for short interventions and for brief psychotherapies is comparable.

Iron deficiency in infancy: is an immigrant more at risk?

QUESTIONS UNDER STUDY: Iron deficiency with or without anaemia is the most common deficiency in the world. Its prevalence is higher in developing countries and in low socioeconomic populations. We aimed at determining and comparing the prevalence of iron deficiency in an immigrant and non-immigrant population. METHODS: Every child scheduled for a routine check-up at 12 months of age was allowed to participate in the study. Haemoglobin, ferritin, anthropometric data, familial and nutritional status were measured. RESULTS: 586 infants were eligible and 463 were included in the study as they had assessment data at 12 months. Children were divided into two groups: immigrants' children and non-immigrants' children. The global prevalence of iron deficiency was 5.7% at 12 months. A significant difference for iron deficiency was noticed between the groups at 12 months (p = 0.01). Among risk factors, immigration (odds ratio 2.91; 95% CI 1.05-8.04) and unemployment (odds ratio 6.08; 95% CI 1.18-31.30) had the higher odds in the multivariable analysis. CONCLUSION: The prevalence of iron deficiency in the immigrant population is higher than in non-immigrants. Immigration and the category of employment are risk factors for iron deficiency, as starting baby cereals before 9 months is a protective factor. Good socioeconomic conditions in Switzerland, the quality of food for pregnant women and young infants may be the explanation. A study up to five years of age is necessary before drawing general conclusions on infancy.

Chest pain in daily practice: occurrence, causes and management

QUESTIONS UNDER STUDY: We assessed the occurrence and aetiology of chest pain in primary care practice. These features differ between primary and emergency care settings, where most previous studies have been performed. METHODS: 59 GPs in western Switzerland recorded all consecutive cases presenting with chest pain. Clinical characteristics, laboratory tests and other investigations as well as the diagnoses remaining after 12 months of follow-up were systematically registered. RESULTS: Among 24,620 patients examined during a total duration of 300 weeks of observation, 672 (2.7%) presented with chest pain (52% female, mean age 55 +/- 19(SD)). Most cases, 442 (1.8%), presented new symptoms and in 356 (1.4%) it was the reason for consulting. Over 40 ailments were diagnosed: musculoskeletal chest pain (including chest wall syndrome) (49%), cardiovascular (16%), psychogenic (11%), respiratory (10%), digestive (8%), miscellaneous (2%) and without diagnosis (3%). The three most prevalent diseases were: chest wall syndrome (43%), coronary artery disease (12%) and anxiety (7%). Unstable angina (6), myocardial infarction (4) and pulmonary embolism (2) were uncommon (1.8%). Potentially serious conditions including cardiac, respiratory and neoplasic diseases accounted for 20% of cases. A large number of laboratory tests (42%), referral to a specialist (16%) or hospitalisation (5%) were performed. Twentyfive patients died during follow-up, of which twelve were for a reason directly associated with thoracic pain [cancer (7) and cardiac causes (5)]. CONCLUSIONS: Thoracic pain was present in 2.7% of primary care consultations. Chest wall syndrome pain was the main aetiology. Cardio - vascular emergencies were uncommon. However chest pain deserves full consideration because of the occurrence of potentially serious conditions.

Regional differences in self-reported screening, prevalence and management of cardiovascular risk factors in Switzerland.

BACKGROUND: In Switzerland, health policies are decided at the local level, but little is known regarding their impact on the screening and management of cardiovascular risk factors (CVRFs). We thus aimed at assessing geographical levels of CVRFs in Switzerland.¦METHODS: Swiss Health Survey for 2007 (N = 17,879). Seven administrative regions were defined: West (Leman), West-Central (Mittelland), Zurich, South (Ticino), North-West, East and Central Switzerland. Obesity, smoking, hypertension, dyslipidemia and diabetes prevalence, treatment and screening within the last 12 months were assessed by interview.¦RESULTS: After multivariate adjustment for age, gender, educational level, marital status and Swiss citizenship, no significant differences were found between regions regarding prevalence of obesity or current smoking. Similarly, no differences were found regarding hypertension screening and prevalence. Two thirds of subjects who had been told they had high blood pressure were treated, the lowest treatment rates being found in East Switzerland: odds-ratio and [95% confidence interval] 0.65 [0.50-0.85]. Screening for hypercholesterolemia was more frequently reported in French (Leman) and Italian (Ticino) speaking regions. Four out of ten participants who had been told they had high cholesterol levels were treated and the lowest treatment rates were found in German-speaking regions. Screening for diabetes was higher in Ticino (1.24 [1.09 - 1.42]). Six out of ten participants who had been told they had diabetes were treated, the lowest treatment rates were found for German-speaking regions.¦CONCLUSIONS: In Switzerland, cardiovascular risk factor screening and management differ between regions and these differences cannot be accounted for by differences in populations' characteristics. Management of most cardiovascular risk factors could be improved.

Spectrum of digoxin-induced ocular toxicity: a case report and literature review.

BACKGROUND: Digoxin intoxication results in predominantly digestive, cardiac and neurological symptoms. This case is outstanding in that the intoxication occurred in a nonagenarian and induced severe, extensively documented visual symptoms as well as dysphagia and proprioceptive illusions. Moreover, it went undiagnosed for a whole month despite close medical follow-up, illustrating the difficulty in recognizing drug-induced effects in a polymorbid patient. CASE PRESENTATION: Digoxin 0.25 mg qd for atrial fibrillation was prescribed to a 91-year-old woman with an estimated creatinine clearance of 18 ml/min. Over the following 2-3 weeks she developed nausea, vomiting and dysphagia, snowy and blurry vision, photopsia, dyschromatopsia, aggravated pre-existing formed visual hallucinations and proprioceptive illusions. She saw her family doctor twice and visited the eye clinic once until, 1 month after starting digoxin, she was admitted to the emergency room. Intoxication was confirmed by a serum digoxin level of 5.7 ng/ml (reference range 0.8-2 ng/ml). After stopping digoxin, general symptoms resolved in a few days, but visual complaints persisted. Examination by the ophthalmologist revealed decreased visual acuity in both eyes, 4/10 in the right eye (OD) and 5/10 in the left eye (OS), decreased color vision as demonstrated by a score of 1/13 in both eyes (OU) on Ishihara pseudoisochromatic plates, OS cataract, and dry age-related macular degeneration (ARMD). Computerized static perimetry showed non-specific diffuse alterations suggestive of either bilateral retinopathy or optic neuropathy. Full-field electroretinography (ERG) disclosed moderate diffuse rod and cone dysfunction and multifocal ERG revealed central loss of function OU. Visual symptoms progressively improved over the next 2 months, but multifocal ERG did not. The patient was finally discharged home after a 5 week hospital stay. CONCLUSION: This case is a reminder of a complication of digoxin treatment to be considered by any treating physician. If digoxin is prescribed in a vulnerable patient, close monitoring is mandatory. In general, when facing a new health problem in a polymorbid patient, it is crucial to elicit a complete history, with all recent drug changes and detailed complaints, and to include a drug adverse reaction in the differential diagnosis.

Characterizing the vulnerability of frequent emergency department users by applying a conceptual framework: a controlled, cross-sectional study.

BACKGROUND: Frequent emergency department (ED) users meet several of the criteria of vulnerability, but this needs to be further examined taking into consideration all vulnerability's different dimensions. This study aimed to characterize frequent ED users and to define risk factors of frequent ED use within a universal health care coverage system, applying a conceptual framework of vulnerability. METHODS: A controlled, cross-sectional study comparing frequent ED users to a control group of non-frequent users was conducted at the Lausanne University Hospital, Switzerland. Frequent users were defined as patients with five or more visits to the ED in the previous 12 months. The two groups were compared using validated scales for each one of the five dimensions of an innovative conceptual framework: socio-demographic characteristics; somatic, mental, and risk-behavior indicators; and use of health care services. Independent t-tests, Wilcoxon rank-sum tests, Pearson's Chi-squared test and Fisher's exact test were used for the comparison. To examine the -related to vulnerability- risk factors for being a frequent ED user, univariate and multivariate logistic regression models were used. RESULTS: We compared 226 frequent users and 173 controls. Frequent users had more vulnerabilities in all five dimensions of the conceptual framework. They were younger, and more often immigrants from low/middle-income countries or unemployed, had more somatic and psychiatric comorbidities, were more often tobacco users, and had more primary care physician (PCP) visits. The most significant frequent ED use risk factors were a history of more than three hospital admissions in the previous 12 months (adj OR:23.2, 95%CI = 9.1-59.2), the absence of a PCP (adj OR:8.4, 95%CI = 2.1-32.7), living less than 5 km from an ED (adj OR:4.4, 95%CI = 2.1-9.0), and household income lower than USD 2,800/month (adj OR:4.3, 95%CI = 2.0-9.2). CONCLUSIONS: Frequent ED users within a universal health coverage system form a highly vulnerable population, when taking into account all five dimensions of a conceptual framework of vulnerability. The predictive factors identified could be useful in the early detection of future frequent users, in order to address their specific needs and decrease vulnerability, a key priority for health care policy makers. Application of the conceptual framework in future research is warranted.

Predicting recurrence after unprovoked venous thromboembolism: prospective validation of the updated Vienna Prediction Model.

The updated Vienna Prediction Model for estimating recurrence risk after an unprovoked venous thromboembolism (VTE) has been developed to identify individuals at low risk for VTE recurrence in whom anticoagulation (AC) therapy may be stopped after 3 months. We externally validated the accuracy of the model to predict recurrent VTE in a prospective multicenter cohort of 156 patients aged ≥65 years with acute symptomatic unprovoked VTE who had received 3 to 12 months of AC. Patients with a predicted 12-month risk within the lowest quartile based on the updated Vienna Prediction Model were classified as low risk. The risk of recurrent VTE did not differ between low- vs higher-risk patients at 12 months (13% vs 10%; P = .77) and 24 months (15% vs 17%; P = 1.0). The area under the receiver operating characteristic curve for predicting VTE recurrence was 0.39 (95% confidence interval [CI], 0.25-0.52) at 12 months and 0.43 (95% CI, 0.31-0.54) at 24 months. In conclusion, in elderly patients with unprovoked VTE who have stopped AC, the updated Vienna Prediction Model does not discriminate between patients who develop recurrent VTE and those who do not. This study was registered at www.clinicaltrials.gov as #NCT00973596.

De novo undifferentiated pleomorphic sarcoma arising from a renal allograft: A case report

To the best of our knowledge, this is the first report of an undifferentiated pleomorphic sarcoma arising from a renal graft. Transplantectomy was performed in a 47-year old woman presenting to the emergency room because of general weakness. Preoperative workup revealed a 5.5 cm malignant mass of the graft which was not present on routine ultrasound performed 12 months earlier. Following transplantectomy, local recurrence developed despite complete tumor resection and interruption of immunosuppression. Despite radiation therapy, the outcome was ultimately fatal. Genetic analysis revealed that the tumor had arisen from donor tissue. Annual ultrasound surveillance might not be enough effective to screen for these rare high grade neoplasms.
