Cost of care pathways before and after appropriate and inappropriate transfers to the emergency department among nursing home residents: results from the FINE study.

BACKGROUND: Transfers of nursing home (NH) residents to the emergency department (ED) is frequent. Our main objective was to assess the cost of care pathways 6 months before and after the transfer to the emergency department among NH residents, according to the type of transfer (i.e. appropriate or inappropriate). METHODS: This was a part of an observational, multicenter, case-control study: the Factors associated with INappropriate transfer to the Emergency department among nursing home residents (FINE) study. Sixteen public hospitals of the former Midi-Pyrénées region participated in recruitment, in 2016. During the inclusion period, all NH residents arriving at the ED were included. A pluri-disciplinary team categorized each transfer to the ED into 2 groups: appropriate or inappropriate. Direct medical and nonmedical costs were assessed from the French Health Insurance (FHI) perspective. Healthcare resources were retrospectively gathered from the FHI database and valued using the tariffs reimbursed by the FHI. Costs were recorded over a 6-month period before and after transfer to the ED. Other variables were used for analysis: sex, age, Charlson score, season, death and presence inside the NH of a coordinating physician or a geriatric nursing assistant. RESULTS: Among the 1037 patients initially included in the FINE study, 616 who were listed in the FHI database were included in this economic study. Among them, 132 (21.4%) had an inappropriate transfer to the ED. In the 6 months before ED transfer, total direct costs on average amounted to 8,145€ vs. 6,493€ in the inappropriate and appropriate transfer groups, respectively. In the 6 months after ED transfer, they amounted on average to 9,050€ vs. 12,094€. CONCLUSIONS: Total costs on average are higher after transfer to the ED, but there is no significant increase in healthcare expenditure with inappropriate ED transfer. Support for NH staff and better pathways of care could be necessary to reduce healthcare expenditures in NH residents. TRIAL REGISTRATION: clinicaltrials.gov, NCT02677272.

Incidence and risk factors for dupilumab associated ocular adverse events: a real-life prospective study.

BACKGROUND: Dupilumab is approved for use in moderate-to-severe atopic dermatitis (AD) and as an add-on maintenance treatment in patients suffering from severe asthma with type 2 inflammation. Ocular adverse events (OAEs) have been reported with dupilumab almost exclusively in patients treated for AD. OBJECTIVES: The objectives of this study were to describe the incidence and nature of dupilumab-induced OAEs and to assess the potential predisposing factors. PATIENTS AND METHODS: We conducted a prospective, single-centre, real-life study in adult AD patients treated with dupilumab, who were systematically examined by an ophthalmologist before and during treatment. RESULTS: Forty-six patients were included prospectively with a median age of 41.1 years and a median initial SCOring Atopic Dermatitis of 46.0 (IQR: 34.5-55.5). OAEs concerned 34.8% of patients and were mostly of mild to moderate severity. Two patients had to discontinue treatment due to OAE. The majority of patients developed or aggravated dry eye disease, with superficial punctate keratitis (SPK). Six patients developed conjunctivitis. Dupilumab-induced OAEs were associated with the following pre-existing parameters: dry eye disease with SPK (Odds ratio (OR); 6.3 [95% confidence interval (CI): 1.3-31.6]), eyelid eczema (OR: 8.7 [95%CI: 1.8-40.6]), history of food allergy (OR 3.8 (95% CI: 1.002-14,070) and IgE serum level> 1000 kU/L (OR:10.6 [CI 95%: 1.2-91.3]). CONCLUSION: Atopic dermatitis patients with eyelid eczema or dry eye disease symptoms may be referred to an ophthalmologist before starting dupilumab to consider initiating preventive eye hydration measures. Further multicentric and translational studies are warranted to better explain OAEs pathophysiology.

Latent class analysis categorizes chronic hand eczema patients according to skin barrier impairment.

BACKGROUND: Chronic hand eczema (CHE) is the most common skin disorder affecting the hands. It causes major physical and psychological burden for patients. Classification of CHE remains challenging because of its aetiological and clinical heterogeneity. OBJECTIVES: Using latent class analysis (LCA) on a large categorical data set, our aim was to identify distinct phenotypes in a cohort of unselected CHE patients based upon clinical, genetic, molecular and physical parameters of the affected skin. METHODS: We performed two independent LCA on a cohort of 71 well-characterized patients that initially integrated clinical severity, total immunoglobulin E plasma level, transepidermal water loss, hydration index, interleukin(IL)-8 lesional skin level, Staphylococcus (aureus and epidermidis) colonization, FLG genotype and the expression (mRNA) of genes involved either in the filaggrin degradation and the natural moisturizing factor synthesis, the cornified envelope formation, the tight junctions' structure and the desquamation process, or encoding antimicrobial peptides and chemokines. RESULTS: The first LCA categorized patients into a group displaying high severity of CHE, high skin barrier impairment, high Staphylococcus colonization, high IL-8 skin level and high frequency of mutation in the FLG gene and a second group with opposite characteristics. The second LCA identified two independent groups of patients categorized by their low or high level of skin barrier impairment and corresponding changes in the expression of the related genes. CONCLUSIONS: Our study suggests that the degree of skin barrier dysfunction is the most important parameter to discriminate CHE patients and probably plays a pivotal role in the pathogenesis of the disease whatever the aetiological factors. As far as we know, this is the first study to address this topic using a statistical categorization method without preconception.

[Creation, implementation and objectives of CARADERM, a national network for rare skin carcinomas - Adnexal neoplasm part]. / Développement, mise en œuvre et objectifs de CARADERM, réseau national cancers cutanés rares ­ partie carcinomes annexiels.

INTRODUCTION: CARADERM is a French national network that includes patients with rare skin adnexal neoplasms. The present paper describes only the adnexal neoplasm part of this network. The primary objective of CARADERM is to improve medical care for malignant skin adnexal neoplasms. A multidisciplinary review group and a centralized pathological review group have been set up. PATIENTS AND METHODS: A dual network of clinicians and pathologists has been set up. Data are recorded in a secure database. RESULTS: The CARADERM network comprises of 38 clinical centres and 22 pathology centres. Between 2014 and 2017, 1598 patients with an adnexal neoplasm were included. Data of interest were documented in 80% of cases. Median patient age was 72 years. Major histological subtypes were sweat gland carcinomas (50%), hair follicle carcinomas (37.7%), and sebaceous gland carcinomas (9.8%). Surgery was the first-line treatment for 81% of patients, including 76.9% with standard surgical margin analysis, and 5.5% with exhaustive margin analysis. 920 patients (57.6%) underwent a national pathology review process. DISCUSSION: The CARADERM network aims at providing assistance in difficult situations concerning diagnosis and care in skin adnexal neoplasms. Analysis of the CARADERM data should allow the creation of a prognostic classification of these rare neoplasms together with recommendations. A national multidisciplinary consensus exists. Translational and therapeutic research is ongoing. CONCLUSION: The CARADERM network is currently recruiting and more data should lead to improved knowledge of these tumours in the coming years.

Sorafenib in metastatic uveal melanoma: efficacy, toxicity and health-related quality of life in a multicentre phase II study.

BACKGROUND: The aim of the study was to analyse efficacy, safety, and health-related quality of life (HRQoL) for sorafenib treatment in patients with metastatic uveal melanoma. METHODS: A multicentre, single-arm phase II trial was conducted. The primary objective was to determine the non-progression rate (RECIST) at 24 weeks for patients receiving sorafenib at a dose of 800 mg per day. Secondary endpoints included progression-free survival (PFS), overall survival (OS), toxicity, and HRQoL. RESULTS: Thirty-two patients were included. Ten patients showed non-progression at 24 weeks (31.2%) without objective tumour responses. The estimated 24-week PFS was 31.2% (95% CI: 14.8%-47.6%) and the estimated 24-week OS was 62.5% (95% CI: 45.4%-79.6%). Ten patients (34.3%) had at least one grade 3 or 4 adverse reaction and 12 patients (41.4%) required dose modifications due to toxicity. At 24 weeks, no patient had an improvement in global HRQoL and 87.5% experienced a permanent increase in physical fatigue. CONCLUSIONS: Sorafenib demonstrated non-progression at 24 weeks in 31.2% of patients. However, 41.4% of patients required dose modifications due to toxicity and no improvement in HRQoL was demonstrated.

Immunocytochemical staining for p53 and Ki-67 helps to characterise urothelial cells in urine cytology.

OBJECTIVE: The presence of atypical cells in urine cytology is unsatisfactory for both cytologists and clinicians. The objective of this study was to test whether p53 and Ki-67 immunostaining could improve urothelial carcinoma (UC) detection on urinary cytology. METHODS: A total of 196 urine samples were analysed, 142 from the bladder, 41 from the upper tract and 13 from ileal bladder replacement. Cytology results were expressed as normal (N) (n = 81), atypia cannot exclude low-grade UC (ALG) (n = 25), suspicious for high-grade UC (SHG) (n = 39) and high-grade UC (HG) (n = 51). Actual diagnoses were confirmed by histopathological analysis, cystoscopic examination or follow-up for at least 1 year. Immunocytochemistry performed on CytoSpin™ slides allowed the determination of the percentage of positive cells with p53 and Ki-67. RESULTS: The median percentage values [first to third quartile] of p53 and Ki-67 were 0 [0-5] and 0 [0-1] for N cytology, 5 [0-40] and 2 [1-10] for ALG, 10 [0-30] and 6 [3-25] for SHG, and 30 [10-80] and 20 [10-30] for HG, respectively. Statistically higher values were observed for both tests (P < 0.001) in positive cytologies (ALG, SHG and HG). The optimal cut-offs were 5% for p53 and 3% for Ki-67. The sensitivity and specificity for the detection of all UC were 86.4% and 76.7% for cytology alone, 81.3% and 93.2% for cytology and p53, 75.7% and 88% for cytology and Ki-67, and 68.9% and 97.5% for cytology, p53 and Ki-67, respectively. CONCLUSION: Using p53 and/or Ki-67 in addition to cytology increases the specificity without penalising the sensitivity.

Improvement of the cytological diagnostic accuracy of follicular thyroid lesions by the use of the Ki-67 proliferative index in addition to cytokeratin-19 and HBME-1 immunomarkers: a study of 61 cases of liquid-based FNA cytology with histological controls.

OBJECTIVES: To evaluate HBME-1, cytokeratin-19 (CK-19) and Ki-67 immunomarkers in order to increase the diagnostic accuracy of preoperative thyroid fine needle aspiration (FNA) cytology. METHODS: Immunocytochemistry against HBME-1, CK-19 and Ki-67 was performed on 123 thyroid FNAs processed by liquid-based cytology (LBC). Statistical analysis was carried out on 61 cases with histological control and sufficient material for one or more of the three markers. The Bethesda System was used for cytological diagnosis. RESULTS: Taking into account all the cytological categories, with a cut-off of 30% of positive cells, HBME-1 (n = 47) and CK-19 (n = 53) showed a sensitivity for malignancy of 66.7% (95% confidence interval, 53.2-80.1) and 90.5% (82.6-98.4) and a specificity of 90.6% (82.3-99) and 75% (63.3-86.7), respectively. For Ki-67 (n = 54) with a cut-off of 1% of positive cells, the sensitivity was 85.0% (75.5-94.5) and the specificity 70.6% (58.4-82.7). In the follicular neoplasm/suspicious for follicular neoplasm (FN/SFN) category (n = 37), which was the focus of the study, papillary thyroid carcinomas (PTCs) were less numerous (four cases, three of which were the follicular variant), the positivity of the three immunomarkers combined showed an overall accuracy of 91% (21/23). The mean percentage of Ki-67-positive cells was increased in malignant lesions, with the exception of follicular variant PTCs: 16% ± 15.6% in two follicular carcinomas, 4.8% ± 3.2% in 13 classical PTCs, 1% ± 1.2% in five follicular variant PTCs and 0.5% ± 1.9% in 34 non-malignant lesions. CONCLUSIONS: Immunocytochemistry using HBME-1, CK-19 and the Ki-67 proliferative index increased the diagnostic accuracy of FNA in the FN/SFN category of the Bethesda System, which may help to distinguish lesions in this category with a low or high risk of malignancy. Thus, clinical management would be improved.

Prospective study on the prevalence and associated risk factors of cryptorchidism in 6246 newborn boys from Nice area, France.

To assess the incidence and risk factors of cryptorchidism in Nice area. A 3-year prospective study was conducted at two maternity wards involving neonatal screening of boys born ≥34weeks of amenorrhoea. Methodology was strict with examination at birth, 3 and 12months by the same paediatrician. Two strictly matched controls were included for each case. Information on child and parents (medical history, pregnancy, lifestyle) was recorded using medical chart and self-administered questionnaires. A total of 102 of 6246 boys were born with cryptorchidism (prevalence 1.6%, 95 included). Half of them were still cryptorchid at three and 12months with, however, 10% of secondary re-ascent (recurrent cryptorchidism) at 12months, justifying long-term follow-up. Cryptorchidism at birth was associated with instrumental delivery, inguinal hernia and urogenital malformations, particularly micropenis and paternal history of cryptorchidism. Our results suggest that maternal exposure to anti-rust or phthalates could be a risk factor, whereas eating fruits daily seemed somewhat protective. Prevalence of cryptorchidism in our area is on the lower bracket compared with other countries, and is associated with both familial and environmental risk factors.

Immune checkpoint inhibitor treatment of a first cancer is associated with a decreased incidence of second primary cancer.

BACKGROUND: Second primary cancers (SPCs) are diagnosed in over 5% of patients after a first primary cancer (FPC). We explore here the impact of immune checkpoint inhibitors (ICIs) given for an FPC on the risk of SPC in different age groups, cancer types and treatments. PATIENTS AND METHODS: The files of the 46 829 patients diagnosed with an FPC in the Centre Léon Bérard from 2013 to 2018 were analyzed. Structured data were extracted and electronic patient records were screened using a natural language processing tool, with validation using manual screening of 2818 files of patients. Univariate and multivariate analyses of the incidence of SPC according to patient characteristics and treatment were conducted. RESULTS: Among the 46 829 patients, 1830 (3.9%) had a diagnosis of SPC with a median interval of 11.1 months (range 0-78 months); 18 128 (38.7%) received cytotoxic chemotherapy (CC) and 1163 (2.5%) received ICIs for the treatment of the FPC in this period. SPCs were observed in 7/1163 (0.6%) patients who had received ICIs for their FPC versus 437/16 997 (2.6%) patients receiving CC and no ICIs for the FPC versus 1386/28 669 (4.8%) for patients receiving neither CC nor ICIs for the FPC. This reduction was observed at all ages and for all histotypes analyzed. Treatment with ICIs and/or CC for the FPC are associated with a reduced risk of SPC in multivariate analysis. CONCLUSION: Immunotherapy with ICIs alone and in combination with CC was found to be associated with a reduced incidence of SPC for all ages and cancer types.

Cross-priming of naive CD8 T cells against melanoma antigens using dendritic cells loaded with killed allogeneic melanoma cells.

The goal of tumor immunotherapy is to elicit immune responses against autologous tumors. It would be highly desirable that such responses include multiple T cell clones against multiple tumor antigens. This could be obtained using the antigen presenting capacity of dendritic cells (DCs) and cross-priming. That is, one could load the DC with tumor lines of any human histocompatibility leukocyte antigen (HLA) type to elicit T cell responses against the autologous tumor. In this study, we show that human DCs derived from monocytes and loaded with killed melanoma cells prime naive CD45RA(+)CD27(+)CD8(+) T cells against the four shared melanoma antigens: MAGE-3, gp100, tyrosinase, and MART-1. HLA-A201(+) naive T cells primed by DCs loaded with HLA-A201(-) melanoma cells are able to kill several HLA-A201(+) melanoma targets. Cytotoxic T lymphocyte priming towards melanoma antigens is also obtained with cells from metastatic melanoma patients. This demonstration of cross-priming against shared tumor antigens builds the basis for using allogeneic tumor cell lines to deliver tumor antigens to DCs for vaccination protocols.

Incidence of auto-immune pemphigus in the Midi-Pyrénées region in 2002-2006.

INTRODUCTION: Auto-immune pemphigus is an organ-specific immune disorder due to pathogenic auto-antibodies. Both genetic and environmental factors have been associated with the occurrence of auto-immune pemphigus. Little is known about the epidemiology of auto-immune pemphigus in western Europe. OBJECTIVE: To evaluate the incidence of auto-immune pemphigus in south-western France (namely the Midi-Pyrénées region) in a 5-year period between 2002 and 2006. MATERIALS AND METHODS: We performed a retrospective study of the annual incidence of auto-immune pemphigus diagnosed in the Midi-Pyrénées region, between January 1, 2002, and December 31, 2006. Possible cases of pemphigus were initially selected using skin direct immunofluorescence (DIF) databases from all laboratories in the Midi-Pyrénées region. Systematic validation of all cases was performed by two of the authors (N.M., M.T.). To qualify as a case of auto-immune pemphigus, patients had to fulfil the following criteria: history of clinical signs of pemphigus as assessed by a dermatologist and a positive DIF. To be included in the study, validated cases of auto-immune pemphigus had to fulfil the following criteria: the date of first positive skin DIF between January 1, 2002, and December 31, 2006, and patient living in the Midi-Pyrénées region at the time of the first positive skin DIF. RESULTS: Between 2002 and 2006, 91 patients with positive DIF were identified. Fifty-four patients with positive DIF did not meet the validation criteria for the study. Thirty-seven cases were included in the analysis. The crude annual mean incidence of auto-immune pemphigus between 2002 and 2006 was 2.7 cases/10(6) inhabitants/year (95% CI: 1.87-3.69). The world-population-standardized annual mean incidence of auto-immune pemphigus was 1.55 (95% CI: 0.99-2.11). CONCLUSION: We report a 1.55/10(6) inhabitants/year world-population-standardized incidence of auto-immune pemphigus in the south-west of France. A nationwide epidemiological study of pemphigus should be performed in France.

[Isolated primary nocturnal enuresis: international evidence based management. Consensus recommendations by French expert group]. / Enurésie nocturne primaire isolée: diagnostic et prise en charge. Recommandations par consensus formalisé d'experts.

OBJECTIVE: The causes and treatment of isolated primary nocturnal enuresis (PNE) are the subject of ongoing controversy. We are proposing consensus practical recommendations, based on a formalised analysis of the literature and validated by a large panel of experts. METHODOLOGY: A task force of six experts based its work on the guide for literature analysis and recommendations and recommendation grading of the French Haute Autorité de Santé (formalized consensus process methodological guidelines) to evaluate the level of scientific proof (grade of 1 to 4) and the strength of the recommendations (grade A, B, C) of the publications on PNE. As a result of this, 223 articles from 2003 on were identified, of which only 127 (57 %) have an evaluable level of proof. This evaluation was then reviewed by a 19-member rating group. Several recommendations, poorly defined by the literature, had to be proposed by a professional agreement resulting from a consultation between the members of the task force and those of the rating group. For its final validation, the document was submitted to a reading group of 21 members working in a wide range of specialist areas and practices but all involved in PNE. RESULTS: The definition of PNE is very specific: intermittent incontinence during sleep, from the age of 5, with no continuous period of continence longer than 6 months, with no other associated symptom, particularly during the day. Its diagnosis is clinical by the exclusion of all other urinary pathologies. Two factors must be identified during the consultation: nocturnal polyuria promoted by excessive fluid intake, inverse secretion of vasopressin, snoring and sleep apnoea. It is sensitive to desmopressin; small bladder capacity evaluated according to a voiding diary and the ICCS formula. It may be associated with diurnal hyperactivity of the detrusor (30 %). It is resistant to desmopressin. Problems associated with PNE are: abnormal arousal threshold, attention deficit hyperactivity disorder (ADHD) (10 %), low self-esteem. The psychological component is not very significant. CONCLUSION: PNE is not psychological in origin. The management of this condition includes: evaluating the intrafamilial tolerance and the child's motivation, evaluating the rate, the volume of urine and wet nights using a diurnal and nocturnal diary; education (sufficient fluid intake at the start of the day, decrease in hyperosmolar intake in the evening, regular and complete urination); specific treatments: desmopressin for polyuric forms (expected success rate of 60-70 %), alarms for forms involving small bladder capacity (expected success rate of 60-80 %); alternative treatments and/or treatments combined with the preceding ones, for refractory forms: oxybutinin, tricyclic antidepressants (risk). Results obtained with hypnosis, psychotherapy, acupuncture, homoeopathy or chiropractic are not currently validated (insufficient level of proof).

Short-term autonomy and survival after hepatectomy in the elderly.

AIM: To study morbi-mortality, survival after hepatectomy in elderly patients, and influence on their short-term autonomy. PATIENTS AND METHODS: This is a retrospective study conducted between 2002 and 2017 comparing patients less than 65 years old (controls) to those more than 65 years old (cases) from a prospective database, with retrospective collection of geriatric data. Cases were divided into three sub-groups (65-70 years, 70-80 years and>80 years). RESULTS: Four hundred and eighty-two patients were included. There was no age difference in number of major hepatectomies (P=0.5506), length of stay (P=0.3215), mortality at 90 days (P=0.3915), and surgical complications (P=0.1467). There were more Grade 1 Clavien medical complications among the patients aged over 65 years (P=0.1737). There was no difference in overall survival (P=0.460) or disease-free survival (P=0.108) according to age after adjustment for type of disease and hepatectomy. One-third of patients had geriatric complications. The "home discharge" rate decreased significantly with age from 92% to 68% (P=0.0001). Early loss of autonomy after hospitalization increased with age, 16% between 65 and 70 years, 23% between 70 and 80 years and 36% after 80 years (P=0.10). We identified four independent predictors of loss of autonomy: age>70 years, cholangiocarcinoma, length of stay>10 days, and metachronous colorectal cancer. CONCLUSIONS: Elderly patients had the same management as young patients, with no difference in surgery or survival, but with an increase in early loss of autonomy.

The prognostic impact of immune-related adverse events during anti-PD1 treatment in melanoma and non-small-cell lung cancer: a real-life retrospective study.

Background: Nivolumab and pembrolizumab, two PD1 inhibitors, trigger immune-related adverse events in approximately 50% of patients. Our objective was to determine whether these immune-related adverse events are associated with patient outcomes. Patients and Methods: Retrospective cohort study, realized at the Institut Universitaire du Cancer de Toulouse, of all the patients treated with nivolumab or pembrolizumab off clinical trials. We included patients (i) diagnosed with unresectable stage III or stage IV melanoma or with recurrent stage IIIB or stage IV non-small cell lung cancer (ii) on nivolumab 3mg/kg or pembrolizumab 2mg/kg every 2 or 3 weeks respectively. Results: Of the 311 patients included (of 641 eligible subjects), 120 (38.6%) had melanoma and 191 (61.4%) had non-small cell lung cancer; 241 (77.5%) were treated with nivolumab with a median follow-up of 24 months (20-29). We observed 166 immune-related adverse events in 116 (37.3%) patients, categorized as "early" (onset before 12 weeks in melanoma and before 8 weeks in lung cancer) in 63 (54.3%) patients. Early and late adverse events were significantly associated with an increase in overall survival: adjusted hazard ratio 0.58 [0.41-0.84] (p = .003) and 0.28 [0.16-0.50] (p < .001) respectively. The overall response rate was significantly increased in patients with an immune-related adverse event (53.9% vs 12.9%, p < .001) Conclusions: This study validates the association between immune-related adverse events and anti-PD1 efficacy in real-life, especially if these events are delayed. Our results, along with further studies on the place of immunosuppressive drugs in the therapeutic strategy, could improve the management of these adverse events.

Evaluation of bladder stimulation as a non-invasive technique for urine collection to diagnose urinary tract infection in infants under 6 months: a randomized multicenter study ("EE-Sti.Ve.N").

BACKGROUND: Febrile urinary tract infection (UTI) is common in infants and needs to be diagnosed quickly. However, the symptoms are non-specific, and diagnosis can only be confirmed after high quality urinalysis. The American Academy of Pediatrics recommends suprapubic aspiration (1-9% contamination) and urinary catheterization (8-14% contamination) for urine collection but both these procedures are invasive. Recent studies have shown a new non-invasive method of collecting urine, bladder stimulation, to be quick and safe. However, few data about bacterial contamination rates have been published for this technique. We hypothesize that the contamination rate of urine collection by bladder stimulation to diagnose febrile UTI in infants under 6 months is equivalent to that of urinary catheterization. METHODS/DESIGN: This trial aims to assess equivalence in terms of bacterial contamination of urinary samples collected by urinary catheterization and bladder stimulation to diagnose UTI. Seven hundred seventy infants under 6 months presenting with unexplained fever in one of four Pediatric Emergency Departments in France will be enrolled. Each child will be randomized into a bladder stimulation or urinary catheterization group. The primary endpoints will be the validity of the urine sample assessed by the presence of contamination on bacterial culture. CONCLUSION: A high recruitment rate is achievable due to the high prevalence of suspected UTIs in infants. The medical risk is the same as that for routine clinical care as we analyze patients with isolated fever. If our hypothesis holds true and the rate of urine contamination collected by bladder stimulation is acceptable, the infants included in the study will have benefited from a non-invasive and reliable means of collecting urine.

An Application May Help Improve Protein Consumption after Bariatric Surgery.

This brief communication suggests that in patients who had bariatric surgery and in whom protein intake is lower than 60 g/d, the use of an application is likely to improve protein intake.

Infant botulism: Two case reports and electroneuromyogram findings.

Botulism is an uncommon severe neuromuscular disorder. We report two recent cases of confirmed infant botulism diagnosed in an 11-week and a 5-month-old infant along with electroneuromyogram (ENMG) findings. Then, we discuss the EMG features of infant botulism. In severe forms of infant botulism, presence of these features might help decide to use botulinum immune globulin. To our knowledge, case 1 is the first case reported in France based on confirmed dust contamination.

Effects of disodium dichloromethylene diphosphonate on bone loss in paraplegic patients.

21 paraplegic patients with recent traumatic spinal cord injury were orally administered 400 (n = 7) or 1,600 (n = 7) mg/d of disodium dichloromethylene diphosphonate (Cl2MDP) and compared with a placebo group (n = 7) to test the preventive effects of the drug on acute bone loss and osteoclastic resorption. Cl2MDP therapy was initiated at a mean of 17.6 d after the onset of paraplegia. The study lasted at least 6 mo, consisting of a 3.5-mo treatment period, and a variable follow-up period. The effects of Cl2MDP were assessed by blood and urine biochemistry, bone histomorphometry on transilial samples, photon absorptiometry of the tibia and fibula, and radiomorphometry of the femur. The elevation in serum and urinary calcium and in urine hydroxyproline observed in the placebo group did not appear under treatment. With both doses of Cl2MDP there was no further decrease in the bone mineral content. In the treated groups, a smaller percentage increase in osteoclastic population was also noted when compared with the placebo group, but this difference was not significant. There was no mineralization defect induced by Cl2MDP, as shown by tetracycline double labeling. It thus appears that at doses ranging between 400 and 1,600 mg, given as early as possible, Cl2MDP can prevent or reduce the development of the acute bone loss of paraplegic patients, without adverse side effects, though it does not prevent the development of heterotopic ossification.
