Economic evaluation of antineoplasic chemotherapy administered at home or in hospitals

OBJECTIVES: Comparative economic evaluations of chemotherapy administered in hospital day-care units or in the home are relatively scarce. Furthermore, most existing evaluations do not include methodologic studies. This study seeks to compare the costs of anticancer chemotherapy with hospital at-home care versus a hospital day-care unit in the Rh?ne-Alpes region of France. METHODS: This study is based on a randomized controlled crossover trial that included 42 patients, to whom chemotherapy courses were alternatively given in both settings. All cost categories were taken into account according to microcosting methods. A detailed assessment was performed on coordination and health care in both structures (marginal costs and average costs), from the viewpoint of society. RESULTS: The marginal cost for one chemotherapy administration was significantly higher with hospital at-home care than in the hospital day-care unit ($232.5 vs. $157, p < .0001). Conversely, the average cost was significantly lower with home care than at the hospital ($252.6 vs. $277.3, p = .0002). CONCLUSIONS: The results show that the interest of developing home care in anticancer chemotherapy is questionable regarding costs. In the French healthcare system, where there is a surplus of hospital beds, marginal costs seem to be more relevant indicators in most cases than average costs.     

Not only training but also exposure to chlorinated compounds generates a response to oxidative stimuli in swimmers

Relations between exposure to chlorinated compounds and biological markers of response to oxidative stimuli were investigated in swimmers, taking into account the effect of training. Twenty-two male swimmers aged 15-25 years were surveyed twice. Prevalence of irritant symptoms and asthma and number of hours of training were reported. Exposure to nitrogen trichloride (NCl3) and blood response to oxidative stimuli [catalase, superoxide dismutase (Cu2+/Zn2+ SOD), glutathione peroxidase (GSH-Px) activities and ceruloplasmin, ferritin and total antioxidant concentrations] were measured. Univariate analyses were completed by multivariate analyses. High prevalences of irritant symptoms and asthma were found. Multivariate analysis confirmed the results of the univariate analyses and showed that Cu2+/Zn2+ SOD activity was increased by exposure and by training (P = 0.01, P = 0.0001, respectively). Erythrocyte GSH-Px was decreased, whereas plasma GSH-Px was increased by exposure (P = 0.002, P = 0.002). No other association was found. Higher irritant symptoms and increases in the activities of erythrocyte Cu2+/Zn2+ SOD and of plasma GSH-Px with exposure support the hypothesis that the production of reactive oxygen species is not only related to training but also to exposure to chlorinated compounds. Other athletes tend to have respiratory problems such as asthma, but the exposure to chlorinated compounds may increase the respiratory disease among swimmers.     

Progressive hearing loss in Fabry’s disease: a case report

Fabry’s disease is a chromosomal X-linked inherited disease, which causes a lack of the lysosomal alpha-galactosidase A enzyme leading to a cellular accumulation of glycosphingolipids. This accumulation leads to various clinical disorders, including inner ear lesions, with sensorineural hearing loss and dizziness. This article proposes to describe a clinical case of a patient suffering from Fabry’s disease with inner ear associated problems and to review the literature focusing on this subject.     

A simulator for maxillofacial surgery integrating 3D cephalometry and orthodontia.

OBJECTIVES: This paper presents a new simulator for maxillofacial surgery that gathers the dental and maxillofacial analyses together into a single computer-assisted procedure. The idea is to first propose a repositioning of the maxilla via the introduction of 3D cephalometry applied to a 3D virtual model of the patient's skull. Orthodontic data are then integrated into this model, using optical measurements of plaster casts of the teeth. MATERIALS AND METHODS: The feasibility of the maxillofacial demonstrator was first evaluated on a dry skull. To simulate malformations (and thus simulate a "real" patient), the skull was modified and manually cut by the surgeon to generate a given maxillofacial malformation (with asymmetries in the sagittal, frontal, and axial planes). RESULTS: The validation of our simulator consisted of evaluating its ability to propose a bone repositioning diagnosis that would restore the skull to its original configuration. An initial qualitative validation is provided in this paper, with a 1.5-mm error in the repositioning diagnosis. CONCLUSIONS: These results mainly validate the concept of a maxillofacial numerical simulator that integrates 3D cephalometry and guarantees a correct dental occlusion.     

Traumatic hip dislocation in childhood

Traumatic dislocation of the hip in childhood is uncommon and can be a consequence of minor trauma. The authors report a series of 35 dislocations in skeletally immature patients. Most were isolated posterior dislocations without acetabular lesions. In 75% of cases, reduction of the dislocation was easy. Nine children required surgery to remove interposed joint capsule and/or osteochondral fragments to achieve anatomic reduction. Outcomes were generally good, except in one patient in whom a displaced fracture of the femoral physis was followed by total head avascular necrosis. One case of partial necrosis had a satisfactory outcome. Epiphyseal necrosis, though uncommon, appeared to be inconsistent to prevent and hard to predict. Bone scan seems to be more effective than MRI for the detection of necrosis.     

In vivo biodistribution and pharmacokinetics of 18F-labelled Spiegelmers: a new class of oligonucleotidic radiopharmaceuticals

Purpose Single-stranded mirror-image oligonucleotides (Spiegelmers) are highly resistant to nuclease degradation and are capable of tightly and specifically binding to protein targets. Here we explored the potential of Spiegelmers as in vivo imaging probes for positron emission tomography (PET).Methods We investigated the biodistribution and pharmacokinetics of [¹⁸F]-l-DNA and [¹⁸F]-l-RNA Spiegelmers by dynamic quantitative whole-body PET imaging after intravenous administration in non-human primates. Their metabolic profile was explored in primates and rats, and ex vivo autoradiography of [¹²⁵I]-l-RNA was performed in rat kidneys, the major organ for Spiegelmer uptake.Results Both [¹⁸F]-l-DNA and [¹⁸F]-l-RNA Spiegelmers were metabolically stable in plasma during 2 h after injection. No evidence of non-specific binding was found with either type of Spiegelmer in any tissue.Conclusion The biodistribution and metabolic profiles of [¹⁸F]-l-DNA and [¹⁸F]-l-RNA Spiegelmers highlight their potential as radiotracers for in vivo imaging applications.
