[Minors in a French custody center: Sociodemographic characteristics, global health and vulnerability factors]. / Mineurs en garde à vue: caractéristiques sociodémographiques, auto-évaluation de la santé et identification de facteurs de vulnérabilité.

Minor offenders are at risk for medico-psycho-social vulnerability, that impacts global health, schooling, professional future, and socio-familial environment; moreover, minors who are victims of violence and neglect are at greater risk of becoming offenders and minor offenders are at greater risk of suffering violence. Few data are currently available regarding global health and vulnerability factors for minors (i.e. those aged under 18) who have been placed in police custody. This study aimed to describe the judicial and social characteristics of these minors, their medical and psychological health status, with the hypothesis that most minors placed in police custody can be considered as abused or neglected, by presenting factors of vulnerability. We carried out a prospective study, including consecutive minors aged of 13 to 18 years old, who had been detained in custody at the Central Police Station of Nantes (France), from October 2012 to May 2013. The sociodemographic characteristics, scores for global health and the data collected from the welfare and judiciary services were analyzed, to identify abused or neglected minors. Ninety-nine teenagers were included: 78 males and 11 females (mean age±standard deviation: 16.5 years±1.01), who had been placed in custody for robbery, with a remarkable proportion of recidivist minors. Our study has highlighted several worrying characteristics of minors in police custody reflecting their vulnerability, as living conditions (no schooling, no fixed address) and irregular or absent medical follow-up; however their scores for global health were not different from the general population. While 49 minors (49.5 %) had already been identified by the welfare services, our study find that 35 added minors of this population should nonetheless be considered as being abused and/or neglected, based on a very high rate of minors already followed by child protection services and/or already penalized. Systematic health screening in custody could help to detect abused and/or neglected minors, in order to provide them access to appropriate medical and social cares. They could be referring to psychiatric or rehabilitation cares, and to the relevant welfare and judiciary services in order to assess if a specific protection measure is needed.

Potential of tannin-rich plants, Leucaena leucocephala, Glyricidia sepium and Manihot esculenta, to reduce enteric methane emissions in sheep.

An in vivo trial was conducted in sheep to investigate the effect of three tropical tannin-rich plants (TRP) on methane emission, intake and digestibility. The TRP used were leaves of Glyricidia sepium, Leucaena leucocephala and Manihot esculenta that contained, respectively, 39, 75 and 92 g condensed tannins/kg DM. Methane was determined with the sulphur hexafluoride tracer technique. Eight rumen-cannulated sheep of two breeds (four Texel, four Blackbelly) were used in two 4 × 4 Latin square designs. Four experimental diets were tested. They consisted in a tropical natural grassland hay based on Dichanthium spp. fed alone (C) or in association with G. sepium (G), L. leucocephala (L) or M. esculenta (M) given as pellets at 44% of the daily ration. Daily organic matter intake was higher in TRP diets (686, 984, 1054 and 1186 g/day for C, G, L and M respectively; p < 0.05) while apparent organic matter total tract digestibility was not affected (69.9%, 62.8%, 65.3% and 64.7% for C, G, L and M respectively; p > 0.05). Methane emission was 47.1, 44.9, 33.3 and 33.5 g/kg digestible organic matter intake for C, G, L and M, respectively, and was significantly lower (p < 0.05) for L and M than for G and C. Our results confirm the potential of some TRP to reduce methane production. The strong decrease in methane and the increase in intake with TRPs may be due to their presentation as pellets.

[Epidermolysa bullosa acquisita and graft-versus-host disease]. / Épidermolyse bulleuse acquise et réaction du greffon contre l'hôte.

BACKGROUND: Epidermolysis bullosa acquisita (EBA) is a rare acquired blistering disorder caused by production of auto-antibody directed against type-VII collagen. Autoimmune disorders can occur after allogenic bone marrow transplantation as manifestations associated with chronic graft-versus-host disease (GVHD). To date, there have been 10 cases reported in the literature concerning autoimmune blistering diseases following allogenic stem-cell transplants. Herein we describe a new case involving EBA. OBSERVATION: A 46-year-old woman developed EBA 4 years after allogenic cord blood transplantation for non-Hodgkin T-cell lymphoma complicated by acute digestive and cutaneous GVHD. At physical examination, she had some cutaneous blisters on the abdomen, arms and face, as well as numerous erosions in the buccal cavity. Direct immunofluorescence microscopy revealed linear IgG and C3 deposits along the dermal-epidermal basement membrane zone. Indirect immunofluorescence showed weak IgG G4 anti-basement membrane zone antibodies, which reacted with the dermal side of 1M NaCl-split skin; the autoantibodies were directed against type-VII collagen. This second case of EBA was evocative of a GVHD blistering disease. After the therapeutic failure of dapsone and of combined mycophenolate-prednisone, treatment with rituximab proved effective. DISCUSSION: EBA may form part of the autoimmune signs associated with chronic GVH. The destruction of basement membrane and of epidermal basal cells that occurs in GVH could give rise to autoimmune bullous disease. However, in our patient, in whom manifestation of chronic GVH was restricted to the lungs, it is difficult to rule out the fortuitous onset of EBA, which presented at a sizeable interval after acute GVH.

Micro-wires self-assembled and 3D-connected with the help of a nematic liquid crystal.

We discuss a method for producing automatic 3D connections at right places between substrates in front of one another. The idea is based on the materialization of disclination lines working as templates. The lines are first created in the nematic liquid crystal (5CB) at the very place where microwires have to be synthesized. Due to their anchoring properties, colloids dispersed into the nematic phase produce orientational distortions around them. These distortions, which may be considered as due to topological charges, result in a nematic force, able to attract the colloids towards the disclinations. Ultimately, the particles get trapped onto them, forming micro- or nano-necklaces. Before being introduced in the nematic phase, the colloids are covered with an adhering and conducting polypyrrole film directly synthesized at the surface of the particles (heterogeneous polymerization). In this manner, the particles become conductive so that we may finally perform an electropolymerization of pyrrole monomers solved in 5CB, and definitely stick the whole necklace. The electric connection thus synthesized is analyzed by AFM, and its strength is checked by means of hydrodynamic tests. This wiring method could allow Moore's law to overcome the limitations that arise when down-sizing the electronic circuits to nanometer scale.

Impact of COVID-19 pandemic on child abuse and neglect: A cross-sectional study in a French Child Advocacy Center.

OBJECTIVE: This study aimed to describe the impact of the first COVID-19 lockdown in France on the activity of a Child Advocacy Center. METHODS: This cross-sectional, observational study included all children involved in the activity of the CAC during the first lockdown, from March 16 to May 10, 2020 and the next 3 months and the corresponding periods in 2018 and 2019. Cases were considered severe when a hospitalization, social alert and/or judicial report to the prosecutor was decided. RESULTS: Data for 1583 children were analyzed. During the lockdown, the global center activity decreased with 26.4 consultations per 100.000 children in 2018, 46 in 2019 and 20.7 in 2020 (p < 0.001). Judicial activity decreased (forensic examinations and child forensic interview recordings), whereas assessment consultations increased. Cases were more severe during the lockdown than in 2019 and 2018 (12.3, 9.4 and 6.04/100.000 children, respectively, p < 0.0001). The global activity of the center increased in the 3 months after the lockdown as compared with during the lockdown (38.2/100.000 versus 20.7/100.000, respectively, p < 0.001) but did not differ from activity in 2018 and 2019. Severe cases were more frequent in the 3 months after the lockdown than the previous years (13.7/100.000 in 2020, 9.62 in 2019 and 8.17 in 2018, p = 0.0002). CONCLUSION: The CAC activity decreased during the lockdown in France but the increase in incidence of severe abuse cases during the lockdown and the next 3 months confirm the need for optimal screening, care and support of child abuse and neglect victims even in the context of health crisis.

Ice volume and climate changes from a 6000 year sea-level record in French Polynesia.

Mid- to late-Holocene sea-level records from low-latitude regions serve as an important baseline of natural variability in sea level and global ice volume prior to the Anthropocene. Here, we reconstruct a high-resolution sea-level curve encompassing the last 6000 years based on a comprehensive study of coral microatolls, which are sensitive low-tide recorders. Our curve is based on microatolls from several islands in a single region and comprises a total of 82 sea-level index points. Assuming thermosteric contributions are negligible on millennial time scales, our results constrain global ice melting to be 1.5-2.5 m (sea-level equivalent) since ~5500 years before present. The reconstructed curve includes isolated rapid events of several decimetres within a few centuries, one of which is most likely related to loss from the Antarctic ice sheet mass around 5000 years before present. In contrast, the occurrence of large and flat microatolls indicates periods of significant sea-level stability lasting up to ~300 years.

Acute bacterial pneumonia in rats increases alveolar epithelial fluid clearance by a tumor necrosis factor-alpha-dependent mechanism.

To study the rate and regulation of alveolar fluid clearance in acute pneumonia, we created a model of Pseudomonas aeruginosa pneumonia in rats. To measure alveolar liquid and protein clearance, we instilled into the airspaces a 5% bovine albumin solution with 1.5 microCi of 125I-human albumin, 24 h after intratracheal instillation of bacteria. The concentration of unlabeled and labeled protein in the distal airspaces over 1 h was used as an index of net alveolar fluid clearance. Since there was histologic evidence of alveolar epithelial injury, several methods were used to measure alveolar fluid clearance, including the use of experiments in rats with blood flow and the use of experiments in rats without blood flow, so that movement across the epithelial barrier would be minimized in the latter group. The results with each method were identical. We found that P. aeruginosa pneumonia increased alveolar liquid clearance over 1 h by 48% in studies with blood flow, and by 43% in rats without blood flow, compared with respective controls (P < 0.05). In both studies, this increase was inhibited with amiloride. However, propranolol had no inhibitory effect, thus ruling out a catecholamine-dependent mechanism to explain the increase in alveolar fluid clearance. An antitumor necrosis factor-alpha neutralizing antibody, instilled into the lung 5 min before bacteria, prevented the increase in alveolar liquid clearance in rats with pneumonia (P < 0.05). Also, TNFalpha (5 microg) instilled in normal rats increased alveolar liquid clearance by 43% over 1 h compared with control rats (P < 0.05). In normal rats instilled with TNFalpha, propranolol had no inhibitory effect. In conclusion, gram-negative pneumonia markedly upregulates net alveolar epithelial fluid clearance, in part by a TNFalpha-dependent mechanism. This finding provides a novel mechanism for the upregulation of alveolar epithelial sodium and fluid transport from the distal airspaces of the lung.

Currarino syndrome as an etiology of a neonatal Escherichia coli meningitis.

We report the case of a 29-day-old baby girl in whom Escherichia coli meningitis led to the diagnosis of Currarino syndrome (CS) (OMIM 176450), an autosomal-dominant genetic disorder associated with sacral agenesis, anorectal malformation, presacral masses and spinal cord malformations. Her condition improved with antibiotics and early surgical treatment. A familial study identified other genetically related individuals with similar symptoms.

Ovulation synchronization following commercial application of ultrasound-guided follicle ablation during the estrous cycle in mares.

A regimen of progesterone plus estradiol (P&E) was used as a standard for ovarian synchronization to test the efficacy and evaluate the commercial application of ultrasound-guided follicle ablation as a non-steroidal alternative for ovulation synchronization in mares. Recipient mares at a private embryo transfer facility were at unknown stages of the estrous cycle at the start of the experiment on Day 1 when they were randomly assigned to an ablation group (n=18-21 mares) or to a P&E group (n=20-21 mares). In the ablation group, mares were lightly sedated and all follicles > or = 10 mm were removed by transvaginal ultrasound-guided follicle aspiration. In the P&E group, a combination of progesterone (150 mg) plus estradiol (10mg) prepared in safflower oil was given daily (im) for 10 d. Two doses of prostaglandin F(2alpha) (PGF, 10mg/dose, im) were given 12 h apart on Day 5 in the ablation group, or a single dose on Day 10 in the P&E group. Human chorionic gonadotropin (hCG, 2500 IU/mare, im) was given at a fixed time, 6 and 10 d after PGF treatment in the ablation and P&E groups, respectively, with the expectation of a follicle > or = 30 mm at the time of treatment. In both the ablation and P&E groups, transrectal ultrasonography was done at the start of the study (Day 1) and again on the day of hCG treatment and daily thereafter to determine the presence of a CL, measure diameter of the largest follicle and detect ovulation. The mean interval from the start of the study and from PGF treatment to ovulation was shorter (P<0.0001) in the ablation group (13.7 and 9.7 d, respectively) compared to the P&E group (22.3 and 13.2 d, respectively). Following fixed-day treatment with hCG after PGF treatment, the degree of ovulation synchronization was not different (P>0.05) between the ablation and P&E groups within a 2-d (56 and 70%) or 4-d (83% and 90%) period. Although ultrasound-guided follicle ablation may not be practical in all circumstances, it excluded the conventional 10-d regimen of progesterone and estradiol and was considered an efficacious and feasible, non-steroidal alternative for ovulation synchronization in mares during the estrous cycle.

[Violent outburst from teenagers in the pediatric emergency room: Complex cases]. / Agitation des adolescents dans les services d'accueil des urgences pédiatriques : problématique des cas dits « complexes ¼.

INTRODUCTION: Teenagers admitted to the emergency room for a violent attacks episode are increasingly numerous. The source of agitation is multifactorial for these teenagers, often with a complex course. They jeopardize hospital wards, which are often ill-suited for and overwhelmed during these outbursts. This study aims to identify and describe all the teenagers admitted to the hospital over 1 year for a violent outburst and discuss their management. METHODS AND EQUIPMENT: Retrospective and descriptive study of teenagers admitted to the pediatric emergency department of the Nantes University Hospital for a violent outburst in 2015. RESULTS: During this 1-year study, 99 teenagers out of a total of 182 consultations were admitted for a violent outburst. We noted that 85% of them had a previous history of a violent outburst, 70% of them were seeing a psychologist, and 56% were followed by the child welfare services. Most of the outbursts took place at home and were hetero-aggressive. Upon arrival at the pediatric emergency ward, 90% of the teenagers had calmed down. The mean time spent in the emergency ward was 3h42min. Finally, 31% of the teenagers were hospitalized in the general pediatric unit, 14% in the children's psychiatric department, and 8% in the adult psychiatry ward. CONCLUSION: We observed a high proportion of complex cases in the teenagers admitted to our emergency department for a violent outburst. These teenagers in distress, with a complex previous history, illustrated the relation between violence against themselves and their own violent behavior toward others. Developing short-stay units for a temporary isolation could be an advantageous multidisciplinary approach to allow somatic, psychological, and social evaluation of these vulnerable patients.

[When and how to report suspected child abuse to child protective services. Construction and evaluation of a specific support tool for primary care physicians]. / Évaluation d'un outil spécifique sur l'information préoccupante pour les médecins généralistes de Loire-Atlantique.

INTRODUCTION: The aim of this study was to create a specific tool and evaluate its impact on the knowledge of primary care physicians (PCPs) in reporting child abuse to child protective services (CPS). MATERIAL AND METHODS: Prospective "before/after" study assessing the knowledge of general practitioners (GPs) registered at the medical board in a French administrative area through anonymous questionnaires. The tool was adapted from the guidelines published in 2014 by the French Health authorities. The main criterion was the median score (/100) calculated for each questionnaire before (Q1) and after (Q2) the dissemination of the tool. These median scores were compared and associations between scores and some PCPs' characteristics were tested through multiple linear regression. RESULTS: A total of 279 GPs answered the first questionnaire (Q1) and 172 answered the second (Q2). PCPs who answered were mainly women (68% and 74%), were between 30 and 50 years old (61% and 66%), practiced in association with other physicians (82% and 84), and had 15-30% children in their patient population. For Q1, the general median was 65 [IQR: 40-81] versus 82 [IQR: 71-91] for Q2 (P<0.001). The PCPs' characteristics leading to significant variations in the scores for Q1 were age older than 50 years, being female, and having been trained in diagnosis and management of child abuse, with the ß coefficient at -16.4 [95% CI: -31.1; -1.69], +8.93 [95% CI: 2.58; 15.27] and +12 [95% CI: 6.33; 17.73], respectively. DISCUSSION: This study confirms the significant impact of this new tool on PCPs' knowledge concerning reporting suspected child abuse to the CPS. CONCLUSION: Wider dissemination of this tool could increase PCPs' awareness and comprehension of when and how to make a report to the CPS.

[Management of post-traumatic aphakia and aniridia: Retrospective study of 17 patients undergoing scleral-sutured artificial iris intraocular lens implantation. Management of aphakia-aniridia with scleral-sutured artificial iris intraocular lenses]. / Prise en charge de l'aphakie et de l'aniridie post-traumatiques. Étude rétrospective de 17 patients opérés d'implants intraoculaires suturés à la sclère à iris artificiel. Gestion de l'aphakie-aniridie par implants suturés à la sclère à iris artificiel.

PURPOSE: To evaluate the long-term outcomes of artificial iris intraocular lenses sutured to the sclera for managing traumatic aphakia and aniridia. METHODS: All consecutive cases receiving a Morcher® combination implant from June 2008 to February 2016 in Edouard-Herriot Hospital (Lyon, France) were included in this single-center retrospective study. Visual acuity, subjective degree of glare, quality of life and surgical complications were evaluated. RESULTS: Seventeen eyes of 17 patients were included, among which 82% were male. The mean age was 42 years. The injuries consisted of 23.5% contusion and 70.5% open globe injuries, of which 41% were globe ruptures. There was one postoperative case. A penetrating keratoplasty was performed at the same time for eight eyes. The mean follow-up was 32 months. Best-corrected visual acuity improved in 41.2%, remained the same in 17.6% and decreased in 41.2% of our cases. Distance vision averaged 1±0.25 line better and near vision 2.2±0.32 lines better when visual acuity was quantifiable before surgery. Glare improved in 80% of patients and remained stable in 20%, decreasing on average from 3.3/5 [min. 3-max. 4; SD: 0.48] before surgery to 1.9/5 [min. 0-max. 4; SD: 1.197] after surgery. Regarding the esthetic results, 78% of the patients declared themselves reasonably to very satisfied; 57% reported no limitation of activities of daily living, and 43% reported mild limitation. Ocular hypertension and glaucoma, found in 40% of eyes, were the main postoperative complications. CONCLUSION: Implantation of prosthetic iris device combined with an intraocular lens appears to be safe and effective in reducing glare disability and improving visual acuity. Close, long-term monitoring is essential for the success of this surgery.

Pleural carcinogenic potency of mineral fibers (asbestos, attapulgite) and their cytotoxicity on cultured cells.

The carcinogenicity of several samples of mineral fibers was tested following injection of 20 mg in the pleural cavity of noninbred Sprague-Dawley rats. Three samples of chrysotile asbestos (mean length: 3.2, 2.1, and 1.2 micron) induced mesotheliomas at a rate of 48, 52, and 19%, respectively. The first sample was acid leached prior to intrapleural injection; in that group, the percentage of mesotheliomas was reduced to 25%. Treatment with amosite and crocidolite resulted in the occurrence of 57 and 56% of mesotheliomas. Acid-treatment of amphiboles did not significantly modify the percentage of mesotheliomas. When the Stanton's fiber dimensions were taken into consideration to correlate with mesothelioma incidence, the observed number of mesotheliomas in the chrysotile-treated animals was much lower than that expected, suggesting that other fiber parameters (chemistry, physicochemistry) play a role in the carcinogenicity. Attapulgite fibers (mean length: 0.77 micron) did not induce tumor, and the mean survival time was of the same order as that observed in the control groups. The injection of quartz resulted in no mesothelioma but did result in 6 malignant histiocytic lymphomas (17%) and 2 malignant schwannomas (6%). In vitro experiments did not show strong correlation between cytotoxicity and the carcinogenic potency of these minerals, but the qualitative cellular responses might give some indications on the fiber's potency. In addition, the in vitro effects of the fibers seem to be modulated by their size.

[HIV infection presenting with bilateral optic neuropathy]. / Neuropathie optique bilatérale révélant une infection par le virus de l'immunodéficience humaine.

We report the case of a 57-year-old man who presented bilateral subacute and painless optic neuropathy after meningopolyradiculitis revealing a primary human immunodeficiency virus infection. Both antiretroviral and steroid treatments were ineffective. Clinical symptoms and evolutive pattern were consistent with a mechanism of microvascular ischaemia of the optic nerve head. Optic neuropathies related to HIV infection are rare compared to those resulting from opportunistic infections. There are several pathophysiological mechanisms involved.

Enhancement of adriamycin antitumor activity by its binding with an intracellular sustained-release form, polymethacrylate nanospheres, in U-937 cells.

We investigated the antitumor activity of Adriamycin on a monocytic-like cancer cell line U-937 after its binding on polymethacrylate nanospheres (diameter, 270-350 nm). Compared to free Adramycin (F-ADR), nanosphere-bound Adriamycin (B-ADR) exhibits a 3-fold enhancement of cytotoxicity, as determined by cell growth inhibition and DNA synthesis, after continuous exposure to 0.02 and 0.04 microgram/ml. The 90% growth inhibition concentration was 0.051 microgram/ml for F-ADR and was 0.018 microgram/ml for B-ADR (P less than 0.001). Furthermore, the nanosphere densities per cell play an important role since for the same drug concentration the higher the density increases, the better the activity is. Indeed, after 4 days of incubation in a medium containing 160 nanospheres at 0.5 fg/cell, the cell counts were 62.8 +/- 12.8% (SD) of the initial inoculum and they were only 16.1 +/- 0.1% after incubation in a medium containing 800 nanospheres at 0.1 fg/cell (P less than 0.001). A comparable enhancement of activity regarding the nanosphere densities was observed after a 24-h exposure to 0.02 and 0.05 microgram/ml. Short-term uptake studies showed that B-ADR accumulation was higher with B-ADR than with F-ADR. In addition, the efflux kinetics was modified. For cells exposed to F-ADR for 4 h, the efflux half-life was 23.7 +/- 7.7 h and the area to infinity under the efflux curve was 8.6 +/- 2.8 micrograms/mg protein x h-1. For cells exposed to B-ADR, the efflux half-life increased to 85.9 +/- 19.2 h and the area to infinity under the efflux curve to 29.6 +/- 6.6 micrograms/mg protein x h-1 (P less than 0.001). Electron transmission microscopy and previous findings have revealed that B-ADR was well internalized into cells. Our data support the hypothesis that B-ADR acts as an intracellular drug release complex after endocytosis. The findings regarding the number of nanospheres per cell and dose-effect relationships are consistent with mechanisms of drug actions extending to membrane domains.

[Leber-Coats' disease: A retrospective study of 10 patients]. / Maladie de Leber-Coats : étude rétrospective sur 10 cas.

INTRODUCTION: Retrospective study analyzing clinical characteristics and treatment of children affected by Leber-Coats' disease. METHOD: Children with Leber-Coats' disease seen in Edouard-Herriot Hospital, Lyon, between January 2004 and September 2013 were included. The following clinical characteristics were reported: sex, age at diagnosis, presenting symptom, Shields' stage, treatment used, and visual outcomes. RESULTS: Ten children were included in our study. Mean age at diagnosis was 5.5 years. The disease was unilateral in 9/10 cases. The presenting symptom was loss of vision in 7/10 cases, strabismus in 3/10 cases, and microphthalmos in 1 case. The diagnosis was made fortuitously during a follow-up of familial congenital cataract in 2 patients. No cases of leukocoria were seen. Shields' stages were distributed as follows: stage 1, 2A and 2B: 1 case each, stage 3A1: 7 cases, stage>3A1: no cases. Laser photocoagulation was used up to stage 2B, combined with cryotherapy in stage 3A. Stage 1 and 2A were associated with relatively good final visual acuity. Significant macular lipid exudate (stage>2A) was associated with a worse prognosis. CONCLUSION: These epidemiological data help us to better characterize these patients' prognosis. Early diagnosis seems to improve visual outcomes.

High-dose chemotherapy with hematopoietic rescue in patients with stage III to IV ovarian cancer: long-term results.

PURPOSE: A series of 53 patients with poor-prognosis epithelial ovarian cancer treated with high-dose chemotherapy (HDC) followed by hematopoietic rescue was retrospectively studied from the day of diagnosis for toxicity and long-term survival analysis. PATIENTS AND METHODS: Patients were treated with surgery followed by cisplatin combination chemotherapy. After second-look operation (SLO), HDC was administered: 23 patients received melphalan (140 mg/m2 on day 1) and 30 patients received a combination of carboplatin (400 mg/m2 on days 1 to 4) and cyclophosphamide (1.6 g/m2 on days 1 to 4). After HDC, autologous stem-cell transplantation was performed for hematologic support. RESULTS: One patient died of cardiac failure after HDC, but the acute toxicity was acceptable for the other patients. With a median follow-up of 81.5 months, the 5-year overall survival rate for the 53 patients was 59.9% and the disease-free survival (DFS) rate at 5 years was 23.6%. Twenty-four patients (45.3%) were alive, 12 with no evidence of disease and 12 with recurrent disease. The best results were achieved in 19 patients with pathologic complete response at SLO (74.2% 5-year overall survival; 32.8% 5-year DFS). CONCLUSION: HDC followed by autologous stem-cell support is a well-tolerated therapeutic approach for patients with poor-prognosis ovarian carcinoma. In this report, the 59.9% survival of 53 patients at 5 years must be compared to the 20% to 30% 5-year survival observed after conventional therapy. These results should be confirmed by an ongoing prospective randomized trial.

Comparison of high-dose therapy and autologous stem-cell transplantation with conventional therapy for Hodgkin's disease induction failure: a case-control study. Société Francaise de Greffe de Moelle.

PURPOSE: To determine the prognostic factors and outcome of first-line induction failure Hodgkin's disease patients who were treated with a salvage regimen of high-dose chemotherapy and autologous stem-cell transplantation, and to compare them with matched, conventionally treated patients. PATIENTS AND METHODS: We retrospectively analyzed data relating to 86 Hodgkin's disease patients who underwent autologous stem-cell transplantation after failure of the first chemotherapy regimen, either because they did not enter a complete remission and experienced progression of disease less than 3 months after the end of their first-line treatment or because they showed evidence of disease progression during first-line therapy. Graft patients were matched with 258 conventionally treated patients (three controls per case) for age, sex, clinical stage, B symptoms, and time at risk; patient data were obtained from international databases. RESULTS: Among the 86 graft patients, the median age at diagnosis was 29 years (range, 14 to 57 years). Thirty-nine percent of patients had stage II disease, 23% had stage III disease, and 38% had stage IV disease. Seventy percent of the patients received chemotherapy and 30% received combined modality therapy; 60% of the patients received a seven- or eight-drug regimen. After this first-line treatment, 91% had disease progression and 9% had a brief partial response. Eighty patients received a second-line treatment; pretransplantation status was as follows: 24% of patients had a complete remission, 38% had a partial remission (PR), 14% had stable disease, and disease progression occurred in 24%. With a median follow-up of 22 months (range, 4 to 105 months) from diagnosis, the 5-year event-free survival and overall survival rates from transplantation were 25% and 35% (95% confidence intervals, 15 to 36 and 23 to 49), respectively. In multivariate analysis, the pretransplantation disease status after salvage therapy was the only significant prognostic factor for survival (PR: relative risk = 2.8, P = .017; progressive disease: relative risk (RR) = 5.26, P < .001). From diagnosis, the 6-year overall survival rates of the graft patients and 258 matched conventionally treated patients were 38% and 29%, respectively (P = .058). CONCLUSION: Autologous stem-cell transplantation represents the best therapeutic option currently available for patients with primary induction failure and is associated with acceptable toxicity. Response to second-line treatment before high-dose chemotherapy is the only prognostic factor that can be correlated with survival.

[Diffuse diabetic macular edema surgery: prospective study of seven cases followed up with optical coherence tomography]. / Chirurgie de l'oedème maculaire chez le patient diabétique: étude prospective de 7 cas suivis en tomographie par cohérence optique.

INTRODUCTION: A prospective study was performed in seven eyes of seven consecutive patients who had vitrectomy for diffuse diabetic macular edema (DME) with ILM premacular delamination as part of this treatment. PATIENTS AND METHODS: All patients had retinopathy and DME. Only one patient had previous grid photocoagulation. In all eyes, there was no ophthalmoscopic evidence of traction from the posterior hyaloid membrane or proliferative tissue, but all patients had no posterior vitreous separation. A clinical examination and optical coherence tomography (OCT) were performed in preoperative and postoperative surgery (1 and 6 months). Pars plana vitrectomy with separation of the posterior hyaloid was performed in seven cases. RESULTS: Only three patients had vitreomacular traction observed on OCT. Statistical analysis revealed a significant decrease in retinal thickness 6 months after surgery. Best corrected visual acuity improved in four patients. CONCLUSION: Vitreous surgery can improve the visual prognosis of some eyes with DME with or without posterior vitreous separation, whether combined or not with vitreomacular traction observed on OCT.
