Preliminary study on the effect of sex on skin cooling response during whole body cryostimulation (-110 °C): Modeling and prediction of exposure durations.

In order to determine the required duration of whole-body exposure to extreme cold (-110 °C) in males and females for achieving the same cold-induced response, a mathematical model of skin cooling kinetics was developed. This modeling is derived from the implementation of a new experimental cryotherapy protocol to obtain continuous skin temperature maps over time. Each 3-min whole-body cryostimulation session was divided into six incremental sessions of 30 s carried out over six consecutive days. Seventeen young, healthy subjects (8 males aged 22.6 ±3.0 years and 9 females aged 23.7 ±4.7 years) agreed to participate in this study. The smallest sex-related difference in temperature was found in the trunk area (2.93 °C after 3 min) while the greatest temperature drop was found in the lower limbs (5.92 °C after 3 min). The largest temperature variation was observed between the trunk and the lower limbs, and peaked at 2.67 °C in males and 6.99 °C in females. For both sexes, skin cooling kinetics showed a strong transient exponential type decrease followed by linear regression behavior. It appeared that for achieving the same cold-induced response, the required duration of cryostimulation is longer for males. For example, a trunk skin cooling of -12 °C could be achieved in 125s for females vs 170s for males (+36% longer); for the lower limbs, the same skin cooling magnitude could be reached after 87s for females vs 140s for males (+62% longer).

Pharmacokinetics and safety of fluconazole and micafungin in neonates with systemic candidiasis: a randomized, open-label clinical trial.

AIMS: The pharmacokinetics (PK) of fluconazole and micafungin differ in neonates compared with children and adults. Dosing instructions in product labels appear to be inconsistent with the emerging scientific evidence. Limited information is available on the safety profile of these agents in neonates. Our objective was to study the population PK and safety of both drugs, randomly administered in neonates with suspected or confirmed systemic candidiasis. METHODS: Neonates were randomized 1:1 to fluconazole (loading dose 25 mg kg-1 ; maintenance dose 12 mg kg-1 day-1 or 20 mg kg-1 day-1 , respectively, for infants <30 weeks or ≥30 weeks' corrected gestational age) or micafungin (loading dose 15 mg kg-1 day-1 ; maintenance dose 10 mg kg-1 day-1 ). PK samples were taken on treatment days 1 and 5. Population parameters were determined using NONMEM and Monte Carlo simulations performed to reach predefined targets. Clinical and laboratory data, and adverse events were collected up to 36 weeks' corrected gestational age or hospital discharge. RESULTS: Thirty-six neonates were enrolled. The median (range) gestational age was 28.2 (24.1-40.1) and 26.8 (23.5-40.0) weeks for fluconazole and micafungin, respectively. Based on 163 PK samples, the median population clearance (l h-1 kg-1 ) and volume of distribution (l kg-1 ) for fluconazole were: 0.015 [95% confidence interval (CI) 0.008, 0.039] and 0.913, and for micafungin were: 0.020 (95% CI 0.010, 0.023) and 0.354 (95% CI 0.225, 0.482), respectively. The loading dose was well tolerated. No adverse events associated with micafungin or fluconazole were reported. CONCLUSION: Based on Monte Carlo simulations, a loading dose for fluconazole and dosing higher than recommended for both drugs are required to increase the area under the plasma drug concentration-time curve target attainment rate in neonates.

[New strategies in specific care for benign prostatic hypertrophy in older men]. / Nouvelles stratégies dans la prise en charge de l'hypertrophie bénigne de la prostate chez le sujet âgé.

Beyond its scientific and ethical competencies, a good doctor is characterized by his communication skills. The ability to listen is fundamental. During an interview, the physician must keep in mind a bio-psycho-social approach while being able to hear the unspeakable and inaudible. Knowledge of patients and their relatives, which seems to be a specific knowledge for general practitioners, offers a lot of information. Among the main sensitive topics that the clinician must identify are: intrafamily violence, domestic violence, substance abuse and anxiety-depressive disorders. In order to improve, the practitioner can use tools such as the Calgary-Cambridge guide and techniques used in Motivational Maintenance.

Au-delà de ses compétences scientifiques et déontologiques, un bon médecin se caractérise par ses compétences communicationnelles. La capacité d'écoute est fondamentale. Durant un entretien, le médecin doit garder à l'esprit une approche bio-psycho-sociale tout en étant capable d'entendre l'indicible et l'inaudible. La connaissance des patients et de leurs proches, qui semble être une connaissance spécifique aux médecins généralistes, offre énormément d'informations. Parmi les principaux sujets sensibles que doit repérer le clinicien, se trouvent : la violence intrafamiliale, la violence conjugale, les abus de substances et les pathologies anxio-dépressives. Afin de s'améliorer, le praticien peut s'aider d'outils tels que le guide de Calgary-Cambridge ainsi que des techniques utilisées en Entretien Motivationnel.

[Evaluation of stone size before flexible ureteroscopy: Which measurement is best?] / Évaluation de la taille des calculs urinaires avant urétéroscopie souple : quelle mesure choisir ?

PURPOSE: To retrospectively assess the clinical utility in ureteroscopy (URS) planning of radiological parameters as predictor of stone-free status after a single flexible ureteroscopy. MATERIAL: Sixty-seven patients with renal stones treated by flexible URS were retrospectively evaluated. To assess the clinical utility of radiological parameters, relationships between stone-free (SF) status and stone burden (maximal diameter, calculated area, calculated volume, cumulative diameter, and tridimentionnal volume [V3D]) were analyzed using the area under the receiver operating characteristics curve and logistic regression. RESULTS: Maximal diameter (AUC=0.75), calculated area (AUC 0.79), calculated volume (AUC=0.79), cumulative diameter (AUC=0.80) and tridimensional volume (AUC=0.82) revealed ability to predict SF status after URS. CONCLUSION: Stone burden evaluation is critical in predicting SF status after a single URS. Planar and volumetric measurements showed equal ability to predict SF status. V3D is more accurate but diameter measurement remains easier in clinical practice. LEVEL OF EVIDENCE: 4.

[Efficacy and safety of available therapies in the management of idiopathic overactive bladder: A systematic review of the literature]. / Hyperactivité vésicale idiopathique : efficacité et tolérance des traitements pharmacologiques : revue de la littérature.

OBJECTIVE: Study the efficacy and adverse events of different pharmacological lines in the treatment of idiopathic overactive bladder (iOAB). METHODS: PubMed research on meta-analyses and randomized controlled trials (RCT) focused on the efficacy and adverse effects of anticholinergics, botulinum toxin and mirabegron since 2005. RESULTS: Ten meta-analyses of anticholinergics were selected; 16 randomized controlled trials (ERC) comparing botulinum toxin A to either anticholinergic or placebo and 10 ERC studying mirabegron. All the molecules studied showed efficacy compared to placebo in the treatment of iOAB. Anticholinergics remain the first-line pharmacological treatment allowing a significant reduction in the number (nb) of incontinence (-5/week) and in the number of urination (-4/week) as well as a perception of subjective improvement of the symptoms reported by 56 % of the patients treated against 41 % for the placebo group (RR: 1.39 [95 % CI: 1.28-1.51]). The most commonly reported side effect is dry mouth (30 % vs. 8 % in the placebo group). Injections of botulinum toxin A appear to be relatively comparable to anticholinergics in the first line with a decrease in urinary emergency incontinence (UTI) of 3.3/d in the toxin group versus 3.4/d in the anticholinergic group (P=0.81). There was also a higher rate of complete resolution of urinary incontinence in the toxin group (27 % vs. 13 % P=0.03) but significant adverse effects such as lower urinary tract infections (33 % vs. 13 % P>0.01). And the risk of using self-catheterization (5 % vs. 0 % P=0.01). In view of the invasive character of the toxin injections and their side effects, this treatment remains a 2nd line therapy. The same is true for mirabegron: similar efficacy (IUU number in the mirabegron group 50mg -1.74 vs. -1.53 In the solifenacin group 5mg, P>0.5) but different side effects with arterial hypertension (the oral dryness rate being comparable to that in the placebo group). The choice of use of anticholinergic or mirabegron should be based on the balance of efficacy/tolerance to be estimated for each patient. CONCLUSION: The different molecules have shown their efficacy in the treatment of iOAB with acceptable tolerance. There is a lack of direct comparisons between treatments available. Further studies are needed to evaluate the possible interest of a combination of these molecules as well as the search for predictive factors of response to these different therapies.

[Diagnosis and treatment of nephrolithiasis and prevention of recurrences]. / Mise au point et traitement des lithiases rénales et prévention des récidives.

INTRODUCTION: despite fluctuations, the prevalence of nephrolithiasis has significantly increased during the last decades in industrialized nations worldwide (1 to 15 %), which has a significant impact on the cost of healthcare. This increased prevalence is mainly explained by diet modifications. Environmental, metabolic and genetic factors may also influence the formation of kidney stones. As a consequence, the medical management of this disease is preferentially multidisciplinary and involves urologists, nephrologists, radiologists, biologists and dietitians. Urological management : may be mandatory during any acute and/or remote phase of an episode of renal colic, in case of residual stones. Several techniques are available: insertion of double J stent, extracorporeal shock wave lithotripsy, ureteroscopy (flexible or rigid), percutaneous nephrolithotomy and more occasionally, open surgery. Nephrological management: is justified in the course of the acute episode and aims to identify the causal factor(s) of kidney stones formation. The diagnostic approach involves a thorough interrogation (personal medical and surgical history, details of the kidney stone disease and family medical history) as well as a metabolic assessment. Moreover, given the high rate of recurrence (about 50 % within 5 to 10 years), individualized secondary prevention measures are necessary. The recommendations should take into account the identified risk factors and any metabolic abnormalities.

INTRODUCTION: la néphrolithiase est une affection dont la prévalence (1 à 15 %) a beaucoup augmenté ces dernières décennies dans les pays industrialisés et a, de ce fait, un impact sur les dépenses en soins de santé. Cette augmentation de prévalence s'explique essentiellement par une modification des habitudes alimentaires. La survenue d'une néphrolithiase peut en outre, être influencée par des facteurs environnementaux, métaboliques voire génétiques. La prise en charge de cette affection est le plus souvent pluridisciplinaire, impliquant urologues, néphrologues, radiologues, biologistes et diététiciens. La prise en charge urologique peut être nécessaire en phase aiguë et/ou à distance de l'épisode de colique néphrétique, pour l'élimination éventuelle de calculs résiduels. Plusieurs techniques sont disponibles : la mise en place de sondes double J, la lithotritie extracorporelle, l'urétéroscopie (souple ou rigide) voire la néphrolithotomie percutanée et plus rarement la chirurgie ouverte. La prise en charge néphrologique est justifiée au décours de l'épisode aigu et vise à identifier la ou les cause(s) ayant conduit à la formation de calculs. La démarche diagnostique comporte un interrogatoire approfondi (antécédents personnels médicaux et chirurgicaux, histoire de la maladie lithiasique et antécédents familiaux) et un bilan métabolique. Par ailleurs, compte-tenu du taux élevé de récidive (environ 50 % dans les 5 à 10 ans), la mise en place de mesures individualisées de prévention secondaire est nécessaire. Ces recommandations doivent tenir compte des facteurs de risque identifiés et des éventuelles anomalies du bilan métabolique.

[Evaluation of adverse events caused by intravesical BCG instillations: Has the strain used a potential implication?]. / Évaluation des effets indésirables des instillations endovésicales par BCG : implication potentielle de la souche utilisée ?

INTRODUCTION: Intravesical instillations of BCG represent an established treatment of high-risk non-muscle-invasive bladder cancer but also carry considerable toxicity. The aim of this work was to identify adverse effects, their impact on the treatment and the possible involvement of the BCG strain used. MATERIAL AND METHODS: To evaluate adverse events in terms of incidence, severity and moment of occurrence, we performed a retrospective analysis of all patients treated with BCG in our institution from 1998 to 2012. RESULTS: One hundred and forty-six patients were retained for analysis, 140 (95.9%) finished their first induction cycle. Thirty patients (20.6%) had to stop the treatment because of BCG-related adverse events, 80% of which happened during the first 3 BCG cycles (12 instillations). The strain used may have had a significant impact: 16 out of 42 patients (38.1%) treated with Connaught (Immucyst®) and 14 out of 104 patients (13.5%) treated with Tice (Oncotice®) had to stop treatment because of BCG related adverse events (P=0.0019) with an odds ratio of 2.83 (IC 95%: 1.52-5.23). CONCLUSION: BCG-related adverse events generally occur at the beginning of the treatment and therefore do not limit the use of BCG maintenance therapy. Good instillation practice and, in our series, the shift from Connaught to Tice strain enabled to significantly reduce BCG-related adverse events through time. The potential implication of the BCG strain used should be evaluated in prospective trials.

[Mucositis after allogeneic stem cell transplantation: Risk factors, clinical consequences and prophylaxis]. / La mucite post-allogreffe de cellules souches hématopoïétiques: facteurs de risque, conséquences cliniques et prévention.

AIM: Oral mucositis is a very common complication of allograft. However, preventive treatments are still limited. The objective of this study is to identify risk factors for onset of oral mucositis in patients undergoing allogeneic hematopoietic stem cells transplantation (HSCT), to measure clinical consequences and to study their evolution according to type of prevention. PATIENTS AND METHODS: All patients undergoing HSCT in hematology unit of CHU Besançon between January 2009 and August 2010 were included, and received according to their choice, either the standard protocol: solution of sodium bicarbonate 1.4% associated with chlorhexidine-chlorobutanol (Eludril(®)) (n=49), or the experimental treatment by the ionic solution, Caphosol(®) (n=42). RESULTS: The overall incidence of severe mucositis and mucositis is respectively 69% and 36%. In multivariate analysis, a myeloablative conditioning (OR=11.1) and prevention of GVHD (graft-versus-host disease) including methotrexate (OR=7.5) appear such as the two significant mucositis risk factors. The presence of mucositis resulting in a significant increase in the incidence of febrile aplasia (P=0.008) and the use of opioid analgesics and parenteral nutrition (P<10(-3)). The risk of acute gastrointestinal GVHD is also increased in severe mucositis (P=0.01). The duration of post-transplant hospitalization is not changed. The type of prevention does not influence the incidence of mucositis (P=0.11). CONCLUSION: The consequences of mucositis are significant and the risk factors identified. The interest of the ionic solution Caphosol(®) seems limited, the incidence of mucositis is not decreased by this prevention.

[Medical complications of extracorporeal lithotripsy]. / Les complications médicales de la lithotriptie extracorporelle.

Extracorporeal shock wave lithotripsy (ESWL) is one of the most frequently applied procedures for the treatment of urolithiasis. ESWL breaks and splits stones by the means of repeated acoustic shock waves. Despite its non invasive nature, ESWL has been intuitively associated with potential complications, mostly related to residual stone fragments. While non stone-related complications are rare (< 1 %), awareness and identification of these complications could help clinicians to prevent and manage them safely and effectively. The current study reviews the pathophysiology, predicting factors and possible preventive measures of non stone-related medical complications after ESWL.

Hydration and clinical warning signs of dengue fever in primary care: An observational prospective study.

OBJECTIVES: Dengue fever is an arbovirosis expanding worldwide, for which hydration has been reported to reduce the risk of hospitalization. Our objective was to estimate the volume of hydration in Reunionese patients with dengue. METHODS: A prospective observational study included patients presenting with a 'dengue-like' syndrome in ambulatory care. General practitioners recruited patients during consultation, and beverage consumption over the previous 24 hours was reported at two different times. Warning signs were defined according to the 2009 WHO guidelines. RESULTS: GPs included 174 patients from April to July 2019. Average oral hydration volume was 1863 mL and 1944 mL, at the 1st and 2nd medical consultations, respectively. Water was the most wide consumed liquid. Drinking at least 5 glasses of liquid was significantly associated with fewer clinical warning signs at the 1st medical consultation (p = 0.044). CONCLUSIONS: Sufficient hydration volume could prevent dengue warning signs. Further studies with standardized measurement of hydration would be needed.

MOVIE: a phase I, open-label, multicenter study to evaluate the safety and tolerability of metronomic vinorelbine combined with durvalumab plus tremelimumab in patients with advanced solid tumors.

BACKGROUND: Anti-programmed cell death protein 1 (PD1)/programmed death-ligand 1 (PD-L1) agents have only moderate antitumor activity in some advanced solid tumors (AST), including breast cancer (BC), prostate cancer (PC), cervical cancer (CC), and head and neck cancer (HNC). Combining anti-PD-L1 with anti-cytotoxic T-lymphocyte-associated protein (CTLA) and chemotherapy may significantly improve efficacy. PATIENTS AND METHODS: MOVIE is a multicohort phase I/II study examining the combination of anti-PD-L1 durvalumab (Durv; 1500 mg IV Q4W) plus anti-CTLA tremelimumab (Trem; 75 mg IV Q4W) with metronomic vinorelbine (MVino; 20-40 mg orally daily) in various AST resistant to conventional therapies. The primary objective of the phase I part was to determine the maximum tolerated dose (MTD) and recommended dose for phase II (RP2D). RESULTS: Among the 14 patients enrolled during phase I, including 13 women and 1 man, 9 had BC, 1 PC, 2 CC, and 2 miscellaneous cancers with high mutational loads. Median age was 53 years. A total of 12 patients were assessable for the dose-escalation part in which only one dose-limiting toxicity (DLT) was observed [one neutropenia without fever, grade (G) 4]. Two (14.3%), four (28.6%), and four (28.6%) patients had G ≥3 adverse events (AEs) related to MVino, Durv, and Trem, respectively. Treatment-related events included mostly clinical AEs with asthenia (eight G2; three G3), colitis (one G2, one G3), diarrhea (one G3), nausea (two G2), dry skin (two G2), maculopapular rash (one G3), and hyperthyroidism (three G2). No toxic death was reported. Preliminary data showed one patient (CC) who presented a complete response and four patients with stable disease (SD). CONCLUSIONS: MTD was not reached and dose level 2 (MVino 40 mg, Durv 1500 mg, Trem 75 mg) was selected as RP2D. The safety profile of the combination was manageable and consistent with previous reports of Trem + Durv or MVino. Phase II is currently ongoing in BC, PC, CC, HNC, and miscellaneous cohorts.

Ribosomal and mitochondrial DNA target for real-time PCR diagnosis of invasive aspergillosis.

The aim of the present study was to assess the diagnostic efficacy of a combination of two quantitative Aspergillus PCR assays, targeting a mitochondrial and a ribosomal target, in patients with risk factors for invasive aspergillosis (IA) and positive galactomannan (GM) antigen. Forty-four patients with hematological malignancies and risk factors for IA according to revised European Organization for Research on Treatment of Cancer and the Mycoses Study Group criteria (EORTC/MSG) criteria and presenting at least two sequential GM-positive sera were included in the study. Mitochondrial PCR was carried out prospectively on all GM-positive serum samples. Ribosomal PCR was carried out retrospectively on frozen stored sera. The sensitivities of mitochondrial and ribosomal PCRs were 58% and 50%, respectively. The diagnostic test performance was improved by using a combination of both PCR assays and by considering a patient PCR positive when at least two positive results were obtained. The sensitivity, specificity, and positive and negative likelihood ratios were 65%, 94%, and 11.8 and 0.37, respectively. A significant association between fatal outcome at 90 days and positive results of ribosomal PCR assays was observed (adjusted hazard ratio = 8.2; 95% confidence interval [CI] = 1.0 to 65.8; P = 0.048). Our results showed that the combination of two PCR assays targeting mitochondrial and ribosomal Aspergillus DNA improves the sensitivity of PCR in the diagnosis of IA in hematological patients with risk factors and positive GM results. This study also confirms that a positive PCR result is associated with a poor prognosis in these patients and should lead to specific antifungal therapy being introduced immediately.

Foot ischemia related to essential thrombocytemia and atherosclerosis.

We report two cases of foot ischemia combining microvascular thrombosis related to essential thrombocytemia (ET) and a proximal ulcerating atherosclerotic plaque. This suggests that myeloproliferative neoplasms could also trigger distal embolism from an unstable atherosclerotic plaque by creating a prothrombotic status. These distal ischemic events were the first ET manifestation and therefore lead to myeloproliferative neoplasm diagnosis. In ET, thrombosis event can occur with a normal platelet count. Furthermore, hemogram should be regularly controlled among JAK2 muted patients considering the frequent evolution from isolated JAK2 mutation to ET.

Description of Participants in the "Atout Age Mobility" Prevention Workshops at the University Hospital Center of La Réunion: A Prospective Study.

INTRODUCTION: As the population ages, loss of autonomy is becoming a priority public health issue. "Atout Age Mobility" prevention interventions for seniors aim to limit frailty, which is a predictive and reversible factor in the loss of autonomy and disability. OBJECTIVES: The objective of this study is to describe the impact of these interventions on the physical performance and quality of life of a pilot sample of participants. DESIGN: We conducted a prospective study named 5P PILOT with 3 months of follow up. SETTINGS: Subjects were recruited by convenience sampling from participants in the "Atout Age Mobility" workshops at Saint Joseph from 04/09/2017 to 29/01/2019. PARTICIPANTS: Retired people over 55 years old with no contraindications to physical activity recruited from participants in the "Atout Age Mobility" workshops in Saint Joseph. Intervention(s) (for clinical trials) or Exposure(s) (for observational studies): All participants completed 12 weeks of physical exercise called the "Atout Age Mobility" workshop, which lasted 60 minutes each week and was supervised by physical activity coaches. Main Outcome(s) and Measure(s): Physical performance was assessed by Short physical performance battery (SPPB), 10-m gait speed and grip strength measurement. Quality of life through the SF-36 test. RESULTS: Ninety-six patients were included and 55 (57.3%) completed the study. There was a significant improvement in gait speed (1.35±0.26m/s vs. 1.27±0.24m/s; p=0.008). There was no significant change in SF-36, grip strength dominant arm and SPPB at the 0.01 significance level. CONCLUSION: The "Atout Ages Mobility" workshops seem to significantly improve gait speed but not other aspects of physical performance or quality of life.

Combining immunotherapy with an epidrug in squamous cell carcinomas of different locations: rationale and design of the PEVO basket trial.

Squamous cell carcinomas (SCCs) are among the most frequent solid tumors in humans. SCCs, related or not to the human papillomavirus, share common molecular features. Immunotherapies, and specifically immune checkpoint inhibitors, have been shown to improve overall survival in multiple cancer types, including SCCs. However, only a minority of patients experience a durable response with immunotherapy. Epigenetic modulation plays a major role in escaping tumor immunosurveillance and confers resistance to immune checkpoint inhibitors. Preclinical evidence suggests that modulating the epigenome might improve the efficacy of immunotherapy. We herein review the preclinical and the clinical rationale for combining immunotherapy with an epidrug, and detail the design of PEVOsq, a basket clinical trial combining pembrolizumab with vorinostat, a histone deacetylase inhibitor, in patients with SCCs of different locations. Sequential blood and tumor sampling will be collected in order to identify predictive and pharmacodynamics biomarkers of efficacy of the combination. We also present how clinical and biological data will be managed with the aim to enable the development of a prospective integrative platform to allow secure and controlled access to the project data as well as further exploitations.

False-positive Aspergillus real-time PCR assay due to a nutritional supplement in a bone marrow transplant recipient with GVH disease.

PCR screening for circulating DNA, especially when combined with antigen testing, has shown promise for the definitive diagnosis of invasive aspergillosis. False positives for Aspergillus real-time PCR assays have been described in several reports, but no sources of fungal DNA contamination could be clearly identified. We report a false-positive case for both galactomannan (GM) antigenemia and Aspergillus PCR due to nutritional supplement intake in a bone marrow transplant recipient with digestive graft-versus-host disease. Our case report also suggests that fungal DNA can pass into the serum from the intestinal tract in the same way as fungal GM. Clinicians should be aware of this possibility, so that the administration of costly, unnecessary antifungal treatments with potential adverse side-effects can be avoided.

Affective response to whole-body cryotherapy: Influence of sex, body mass index, age, time of day, and past experience.

OBJECTIVE: Whole-Body Cryotherapy (WBC) has seen a recent surge in popularity with patients with inflammatory conditions, athletes, and even people seeking to improve general health and quality of life. WBC treatment usually requires participation in a dozen of 3-min long sessions. But compliance is considered difficult due to possible cold-induced unpleasant sensations. Based on hedonic psychology assumptions, ratings of pleasure-displeasure experienced during a taks or activity may be important to understand individual differences in attendance. METHODS: Two hundred fifty nine customers from two French cryocenters took the Feeling Scale immediately after their first WBC session. RESULTS: End affect appeared to be negatively valenced (M = -1.85, SD = 1.38, 95 % confidence interval: -2.02 to -1.68). Additional statistical analyses revealed a moderating influence of past experience, in women only. Similarly, BMI was found to be negatively associated with displeasure in women, but not in men. CONCLUSION: These findings are discussed and further research directions are suggested.

Effects of Whole-Body Cryostimulation (-90°C) on Somnolence and Psychological Well-Being in an Older Patient with Restless Legs Syndrome.

BACKGROUND: We aimed at evaluating the feasibility and effects of intense (i.e. -90°C) whole-body cryostimulation (WBC) on somnolence and psychological well-being in an older-adult patient diagnosed with restless legs syndrome (RLS). METHODS: An interrupted time series approach was used in which the efficacy of cryostimulation was evaluated by measuring self-reported fatigue, wake time sleepiness, and well-being several times prior to, during, and after exposure to treatment (i.e. daily 3-min sessions of intense WBC). RESULTS: No adverse event occurred. Reported levels of sleepiness decreased immediately following the beginning of the treatment phase. In the same time, self-reported well-being significantly increased. Effects sizes were of large magnitude. CONCLUSION: In summary, the present study demonstrated that daily exposure to extremely cold air in an enclosed space for 2 weeks was feasible and effective in promoting physical and psychological states in an older patient with sleep disturbances.

[Clinical audit on the use of expensive systemic antifungals in the Besançon University Hospital]. / Audit clinique des prescriptions d'antifongiques systémiques couteux au centre hospitalier universitaire de Besançon.

UNLABELLED: The continuous improvement policy for healthcare quality requires practice evaluation. The principle of a clinical audit is to compare practice to guidelines. Prescription guidelines on antifungal agent use has been available in our hospital since 2003. It was updated in 2005 and 2006. OBJECTIVE: The aim of this study was to assess compliance to guidelines, with an audit of prescriptions: amphotericin B lipid formulation, voriconazole and caspofungin, expensive antifungals concerned by the budget allowance correlated to activity, subject to supplementary reimbursement to the coded Homogeneous Group of Diseases. METHOD: The assessment criteria were: relevance of the indication, absence of a better alternative, complying to recommended dosage, loading dose and timing. This retrospective study dealt with all prescriptions of all departments, from January to May 2007. RESULTS: Hundred and eighteen prescriptions were retrospectively analyzed for 81 patients. The rate of overall conformity was 54%. Antifungal therapy was justified for 113 prescriptions (96%). In 30% of the cases, a more efficient alternative was advised, cheaper or less toxic. The dosage and the charge dosing were right in 92% and 80% of the cases respectively. CONCLUSION: This audit allowed assessing good-use of antifungals. We showed an over-prescription of caspofungin and sometimes insufficient regimen of voriconazole dosages for children. Reporting these audit results and development of new international guidelines stress the need to update local recommendations regularly.
