Construct validity of the French version of the PRWE (Patient Rated Wrist Evaluation) with the French version of the DASH (Disabilities Arm Shoulder and Hand) is good to very good in a population of patients with wrist injuries in an inpatient rehabilitation unit

Objective.- The Patient-Rated Wrist Evaluation is a specific questionnaire for the wrist [1]. It consists of 15 questions with a total score of 100. It was recently translated into French [2]. However, its validity has not been tested in this language. The Disabilities Arm Shoulder and Hand (DASH), with well-established psychometric properties, is considered as the reference questionnaire for the evaluation of upper extremities. The objective of this study is to measure the construct validity of the PRWE-F with the DASH-F in patients with wrist pathology.Patients and methods.- Fifty-one patients (40 m, 11 w, mean age 42 years), 25 fractures of the radius and 26 lesions of the carpus.Questionnaires PRWE-F and DASH-F at entry and at discharge (0 to 100). Calculation of the construct validity of the PRWE-F comparing with the DASH-F with Pearson correlation coefficients (r) at entry and at discharge. Level of significance (alpha) was set at 5%.Results.- Correlation DASH/PRWE at entry: r = 0.799 (95% CI 0.671 to 0.881), P < 0.0001. Correlation DASH/PRWE at discharge: r = 0.847 (95% CI: 0.745 to 0.910), P < 0.0001.Discussion.- The construct validity of the two instruments indicates that they measure the same concept. Our correlation between DASH-F and PRWE-F, going from 0.799 to 0.847, are comparable to those published in different languages (0.71 to 0.84) [3,4]. The questionnaires PRWE-F can thus be used in rehabilitation patients presenting with wrist pathologies; it is comparable to the DASH but described by MacDermid [1] to be more specific. Compared to the DASH it has the advantage of consisting of two dimensions. Its construct validity is excellent. This questionnaire should be evaluated in other populations, and it should be compared with hand questionnaires more specific than the DASH.

Chronic rejection of allogenic dermal grafts in 73 % TBSA burn patient

Rationale: Allogenic grafts are an excellent way to temporarily cover a wound. It prevents the loss of electrolytes and water, reduces the risk of infection and diminishes pain. Another advantage of the allograft is in circumventing problems such as the morbidity of skin graft donor sites. We present here the case of a patient grafted in 1991 with cultured epidermal autografts (CEA) and allogenic skin transplants on his legs, outlining the risks and potential long-term complications. Methods: The 40-year-old male patient was treated with allogenic Split Thickness Skin Graft (STSG) transplantations, CEA and Cyclosporine-A therapy. Allogenic STSG for lower extremities were harvested from a female HIV-negative organ donor. They were transplanted, de-epithelialized and subsequently covered with CEAs. Cyclosporine-A was administered systemically from the first day following transplantation until three weeks after the last CEAs were placed on the allogenic dermis. Results: Immediate results showed a 90% successful grafting under cyclosporine therapy. However, some lesions were still present 16 months later. The skin was hard with little or no elasticity. Five years after the transplantation there were no more lesions. However, a 10-year follow-up showed new ulcers on both lower extremities. All the skin of the right leg was removed and replaced by STSG from the patient's back. Postoperative results were excellent with a 100% graft take. The anatomopathology showed dermo-hypodermic tissue with fibrosis of the dermis, vasculopathy and chronic ulcers compatible with chronic rejection. Conclusion: While early functional results of the allografts may seem encouraging, their long-term evolution remains uncertain and, in this case, presents complications. The apparent antigenic effect of the dermal tissue may be controlled with long-term immunosuppression which may cause important secondary effects. Even with such treatments, 15 years after organ transplantation, about 35% of a transplant is no longer functional. It is therefore important to take these long-term observations into consideration when treating sensitive areas such as hands or a face.

PROBLEMATIQUE DE LA CULTURE EN MEDECINE DE FAMILLE, UNE APPROCHE CENTREE SUR LE PATIENT

Problématique : En réaction à l'émergence de société plurielle, la communauté médicale a mis en place des outils de prise en charge de l'altérité. Cependant, la culture, issue notamment des origines, des croyances et des expériences est unique à chaque patient et lui sert à appréhender la maladie. Ce pourquoi, les outils de prise en compte de la culture, et de valorisation du patient, peuvent être potentiellement étendus à tous. Objectifs : Déterminer la place de la culture en médecine de famille, les enjeux qui en dépendent et la pertinence de l'utilisation des compétences transculturelles avec tous les patients. Perfectionner ces compétences dans le but de créer un modèle bio-psycho-socio-culturel améliorant la communication et la compréhension entre patients et thérapeutes. Méthodologie : Réalisation d'une revue de la littérature en déterminant comment la culture est intégrée à la médecine sous forme de savoir théorique.

Report of one case of bilateral cryptorchism with non-palpable testes in a 26-year old patient with progressive muscle dystrophy. Physical examination and ultrasound study to detect the testicular location were inconclusive. An analysis is made of data obtained with the NMR study as well as a review of the advantages and contributions from this new technique in the location and characterization of undescended testes.

Impact de la chirurgie bariatrique sur la santé et la qualité de vie du patient obèse [Impact of bariatric surgery on health and quality life of obese patients]

The important weight loss due to bariatric surgery allows to improve and even correct, a great part of the comorbidities induced by obesity, as well as quality of life, and to reduce the coming out of cardiovascular and metabolic diseases in operated patients. The impact of surgical treatment on the patient's health and quality of life also allows to reduce direct and indirect costs of morbid obesity. However, its effects on mortality have not yet been clearly proved. The preoperative evaluation and the long term follow-up by a skilled team are essential to reduce potential complications, especially on the nutritional field and the risks of recovered weight linked to binge eating disorders.

Cardiac re-synchronization therapy in a patient with isolated ventricular non-compaction: a case report.

Isolated ventricular non-compaction (IVNC) is a rare, congenital, unclassified cardiomyopathy characterized by prominent trabecular meshwork and deep recesses. Major clinical manifestations of IVNC are heart failure, atrial and ventricular arrhythmias, and thrombo-embolic events. We describe a case of a 69-year-old woman in whom the diagnosis of IVNC was discovered late, whereas former echocardiographic examinations were considered normal. She was known for systolic left ventricular dysfunction for 3 years and then became symptomatic (NYHA III). In the past, she suffered from multiple episodes of deep vein thrombosis and pulmonary embolism. Electrocardiogram revealed a wide QRS complex, and transthoracic echocardiography showed typical apical thickening of the left and right ventricular myocardial wall with two distinct layers. The ratio of non-compacted to compacted myocardium was >2:1. Cardiac MRI confirmed the echocardiographic images. Cerebral MRI revealed multiple ischaemic sequellae. In view of the persistent refractory, heart failure in medical treatment of patients with classical criteria for cardiac re-synchronization therapy, as well as the ventricular arrhythmias, a biventricular automatic intracardiac defibrillator (biventricular ICD) was implanted. The 2-year follow-up period was characterized by improvement of NYHA functional class from III to I and increasing in left ventricular function. We hereby present a case of IVNC with favourable outcome after biventricular ICD implantation. Cardiac re-synchronization therapy could be considered in the management of this pathology.

Patient adherence and the choice of antihypertensive drugs: focus on lercanidipine.

Despite the development of many effective antihypertensive drugs, target blood pressures are reached in only a minority of patients in clinical practice. Poor adherence to drug therapy and the occurrence of side effects are among the main reasons commonly reported by patients and physicians to explain the poor results of actual antihypertensive therapies. The development of new effective antihypertensive agents with an improved tolerability profile might help to partly overcome these problems. Lercanidipine is an effective dihydropyridine calcium channel blocker of the third generation characterized by a long half-life and its lipophylicity. In contrast to first-generation dihydropyridines, lercanidipine does not induce reflex tachycardia and induces peripheral edema with a lower incidence. Recent data suggest that in addition to lowering blood pressure, lercanidipine might have some renal protective properties. In this review we shall discuss the problems of drug adherence in the management of hypertension with a special emphasis on lercanidipine.

HIV-1 superinfection with a triple-class drug-resistant strain in a patient successfully controlled with antiretroviral treatment.

We report a case of HIV-1 superinfection (HSI) with a clade B, triple-class resistant virus in a patient successfully controlling viremia with continuous combination antiretroviral therapy started 8 years earlier during primary HIV infection. The course of HIV infection prior to HSI was monitored in both the source partner and recipient (8 and 11 years, respectively) and 4 years following HSI. This case report demonstrates re-infection with HIV-1 despite effective combination antiretroviral therapy.

Fluoroscopy-guided procedures in cardiology: is patient exposure being reduced over time?

The number of fluoroscopy-guided procedures in cardiology is increasing over time and it is appropriate to wonder whether technological progress or change of techniques is influencing patient exposure. The aim of this study is to examine whether patient dose has been decreasing over the years. Patient dose data of more than 7700 procedures were collected from two cardiology centres. A steady increase in the patient dose over the years was observed in both the centres for the two cardiological procedures included in this study. Significant increase in dose was also observed after the installation of a flat-panel detector. The increasing use of radial access may lead to an increase in the patient exposure. The monitoring of dose data over time showed a considerable increase in the patient exposure over time. Actions have to be taken towards dose reduction in both the centres.

The Patientʼs Perception of Eosinophilic Esophagitis Related Symptoms: a Qualitative Content Analysis

Background and Aims: The international EEsAI study group is currently developing an activity index for Eosinophilic Esophagitis (EoE). A potential discrepancy between patient and physician reported EoE symptoms has not been assessed yet. Therefore, we aimed to evaluate patient reported items describing their EoE activity and to compare these with the physicianʼs perception. Methods: A questionnaire was sent to 100 EoE patients in Switzerland. EoE-related symptoms dependent and independent of food intake were reported by patients. Results were analyzed using a qualitative content analysis and compared with symptoms reported by international EoE experts in Delphi rounds. Results: The questionnaire response rate was 64/100. The following items were developed by combining categories based on patients answers: food-consistency related dysphagia, frequency and severity of dysphagia, food impaction, strategies to avoid food impaction, food allergy, drinking-related retrosternal pain. The following food categories associated with dysphagia were identified: meat, rice, dry bread, French fries, raw, fibrous foods, others. Sports and psychological stress were identified as triggers for non-food intake related EoE symptoms. A good correlation was found between patient and physicianʼs reported EoE related symptoms. Conclusions: There is a good correlation between patient reported symptoms and the physicianʼs perception of clinical items as reported by international EoE experts. These patient reported outcomes will now be incorporated into the EEsAI questionnaire that measures EoE activity.

Spurious hyperphosphatemia in a patient with alteplase-locked central venous catheter.

Alteplase has been shown to be effective in preventing central venous access clotting in patients on hemodialysis. Because of a high phosphorus content in its excipient, it can inadvertently contaminate blood samples, leading the physician in care of the patient to erroneously increase dialysis time or change diet in order to control the pseudo-hyperphosphatemia.

Does introduction of thresholds in decision aids benefit the patient?: Comparison between findings-based and threshold-based diagnostic decision aids.

PURPOSE: To assess how different diagnostic decision aids perform in terms of sensitivity, specificity, and harm. METHODS: Four diagnostic decision aids were compared, as applied to a simulated patient population: a findings-based algorithm following a linear or branched pathway, a serial threshold-based strategy, and a parallel threshold-based strategy. Headache in immune-compromised HIV patients in a developing country was used as an example. Diagnoses included cryptococcal meningitis, cerebral toxoplasmosis, tuberculous meningitis, bacterial meningitis, and malaria. Data were derived from literature and expert opinion. Diagnostic strategies' validity was assessed in terms of sensitivity, specificity, and harm related to mortality and morbidity. Sensitivity analyses and Monte Carlo simulation were performed. RESULTS: The parallel threshold-based approach led to a sensitivity of 92% and a specificity of 65%. Sensitivities of the serial threshold-based approach and the branched and linear algorithms were 47%, 47%, and 74%, respectively, and the specificities were 85%, 95%, and 96%. The parallel threshold-based approach resulted in the least harm, with the serial threshold-based approach, the branched algorithm, and the linear algorithm being associated with 1.56-, 1.44-, and 1.17-times higher harm, respectively. Findings were corroborated by sensitivity and Monte Carlo analyses. CONCLUSION: A threshold-based diagnostic approach is designed to find the optimal trade-off that minimizes expected harm, enhancing sensitivity and lowering specificity when appropriate, as in the given example of a symptom pointing to several life-threatening diseases. Findings-based algorithms, in contrast, solely consider clinical observations. A parallel workup, as opposed to a serial workup, additionally allows for all potential diseases to be reviewed, further reducing false negatives. The parallel threshold-based approach might, however, not be as good in other disease settings.

Indicateurs sécurité en obstétrique : une étude Delphi [Patient safety indicators for obstetrics: a Delphi based study]

OBJECTIVE: Clinical indicators are increasingly used to assess safety of patient care. In obstetrics, only a few indicators have been validated to date and none is used across specialties. The purpose of this study was to identify and assess for face and content validity a group of safety indicators that could be used by anaesthetists, obstetricians and neonatologists involved in labour and delivery units. MATERIALS AND METHODS: We first conducted a systematic review of the literature to identify potential measures. Indicators were then validated by a panel of 30 experts representing all specialties working in labour and delivery units. We used the Delphi method, an iterative questionnaire-based consensus seeking technique. Experts determined on a 7-point Likert scale (1=most representative/7=less representative) the soundness of each indicator as a measure of safety and their possible association with errors and complications caused by medical management. RESULTS: We identified 44 potential clinical indicators from the literature. Following the Delphi process, 13 indicators were considered as highly representative of safety during obstetrical care (mean score</=2.3). Experts ranked 6 of these indicators as being strongly associated to potential errors and complications. CONCLUSIONS: We identified and validated for face and content, a group of six clinical indicators to measure potentially preventable iatrogenic complications in labour and delivery units.
