ABSTRACT

Corneal haze represents subepithelial corneal fibrosis, a manifestation of a pathological healing process. It occurs as a result of an epithelial-stromal lesion involving a break in the epithelial barrier. It is an inflammatory response that involves the migration, multiplication and differentiation of keratocytes into mature myofibroblasts, causing loss of corneal transparency. Although it is a transient phenomenon, this complication is feared following refractive photokeratectomy (PRK), because it can cause alterations in the quality of vision, refractive regression and decreased visual acuity. The severity of these symptoms is correlated with the severity of the corneal haze, which can be assessed clinically or by objective means such as corneal densitometry measurement. The frequency and severity of corneal haze increase with the depth of photoablation in PRK and are therefore increased during the treatment of severe ametropia. Considering that no consensus exists, the application of mitomycin C (MMC) intraoperatively and topical corticosteroids postoperatively are conventionally used to inhibit collagen synthesis, sometimes in combination with various protocols depending on the center or surgeon. This review of the literature reports the current knowledge on corneal haze, in order to better understand it and optimise its prevention in the context of a decreased MMC supply, which has occurred in the past and could recur in the future.

ABSTRACT

Presence of air in the spinal canal, called pneumorrhachis (PR) is a rare and likely unrecognized condition often due to traumatic or iatrogenic causes. Most of PR occur after repeated epidural ponction or penetrating trauma or brutal intra-alveolar increase especially in asthma attack. Non traumatic and non iatrogenic causes are uncommon but can appear in a neoplastic context.


La présence d'air dans le canal spinal, ou pneumorachis (PR), est une entité rare, souvent méconnue, habituellement de nature traumatique ou iatrogénique. Le PR survient essentiellement à la suite de ponctions épidurales répétées, d'un traumatisme pénétrant ou d'une majoration brutale de la pression intra-alvéolaire, notamment lors d'une crise asthmatique. Le PR non traumatique et non iatrogénique est excessivement rare, survenant alors volontiers dans un contexte néoplasique.

ABSTRACT

PURPOSE: Characterize and determine the frequency of dissections of the supra-aortic arteries (SAA) and injuries to the cervical spine and pharyngolaryngeal cartilages viewed on CT scans after an attempted suicide by hanging. MATERIALS AND METHODS: A retrospective, single-centre study of all patients admitted for attempted suicide by hanging between January 2010 and June 2017 who received CT angiography of the SAA. Search for signs of dissection of the cervical arteries and injuries to the brain, spinal column and pharyngeal and laryngeal cartilages. The results were compared with the initial clinical severity, which was assessed indirectly by whether patients were initially admitted in an intensive care unit (ICU) or in an emergency department (ED). RESULTS: Out of 162 patients included, 4 presented with SAA dissection (2.5%), comprising 3 vertebral arteries and 1 external carotid artery. The cases in question were of 4 men, all in cardiac arrest on arrival and all were treated in ICU. Of the most serious cases, 18/72 (25%) had anoxia-related injuries and one also presented with a C2 fracture. No vascular lesions or signs of cerebral anoxia were observed in the 90 ED patients. Nevertheless, pharyngeal and laryngeal fractures were observed in both groups, with no significant difference. CONCLUSION: In our study, 2.5% of CT angiograms performed after an attempted hanging revealed SAA dissection. Crucially, only most severe patients, who have been immediately admitted to ICU suffered SAA. These results call into question the systematic indication of this exam in cases of hanging attempts.

ABSTRACT

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has spread worldwide from epicenter of Wuhan, China since December 2019. The aim of our study was to describe the clinical characteristics and outcome of hospitalized patients with SARS-CoV-2 pneumonia at the Toulouse university hospital, France. PATIENTS AND METHODS: We selected the patients included from March 7, 2020 to April 20, 2020 in the retrolective Covid-clinic-Toul cohort that follows all hospitalized patients with SARS-CoV-2 infection at the Toulouse Hospital. Cases were confirmed by real-time reverse transcriptase polymerase chain reaction. We report demographics, clinical, biological and radiological features, as well as unfavorable outcome at Day 14 after admission (admission in an intensive care unit, mechanical ventilation, death). RESULTS: Among 263 hospitalized patients, the median age was 65 years and 155 (58.9%) were males. Two hundred and twenty-seven patients (86.3%) had at least one comorbidity. The median time from first symptom to hospital admission was 7.0 days (interquartile range: 4-10). On day 14 after admission, 111 patients (42.2%) had been transferred to intensive care unit (ICU), including 50 (19.0%) on Day 1; 61 (23.1%) needed mechanical ventilation and 19 patients (7.2%) had died. Patients admitted to ICU at Day 1 of admission (n=50) were more frequently men (66.0% vs 57.3%), smokers (25.0% vs 7.1%), with obesity (42.0% vs 24.7%) and had a higher mean level of C-reactive protein (median: 110.9mg/L vs 46.2mg/L). CONCLUSION: This cohort provides epidemiological data on SARS-CoV-2 in hospitalized patients in a University hospital in the South of France.

ABSTRACT

OBJECTIVES: The early identification of patients with Acute Heart Failure Syndrome (AHFS) among patients admitted to the Emergency Department (ED) with dyspnoea can facilitate the introduction of appropriate treatments. The objectives are to identify the predictive factors for AHFS diagnosis in patients with acute dyspnoea (primary objective) and the clinical 'gestalt' (secondary objective) in ED. METHODS: PREDICA is an observational, prospective, multicentre study. The enrolment of patients admitted to the ED for nontraumatic acute dyspnoea and data collection on admission were recorded by the patient's emergency physician. The AHFS endpoints were assessed following a duplicate expert evaluation by pairs of cardiologists and emergency physicians. Step-by-step logistic regression was used to retain predictive criteria, and the area under the receiver operating characteristic (ROC) curve of the model was constructed to assess the ability of the selected factors to identify real cases. The probability of AHFS was estimated on a scale from 1 to 10 based on the emergency physician's perception and understanding (gestalt). RESULTS: Among 341 patients consecutively enrolled in three centres, 149 (44%) presented AHFS. Eight predictive factors of AHFS were detected with a performance test showing an area under the model ROC curve of 0.86. Gestalt greater than or equal to five showed sensitivity of 78% and specificity of 90% (AUC 0.91) and diagnosed 88% of AHF in our population. CONCLUSIONS: We identified several independant predictors of final AHFS diagnosis. They should contribute to the development of diagnostic strategies in ED. However, unstructured gestalts seem to perform very well alone.

ABSTRACT

We have studied the low temperature electrical transport properties of La x Sr1-x CuO2 thin films grown by oxide molecular beam epitaxy on (1 1 0) GdScO3 and TbScO3 substrates. The transmission electron microscopy measurements and the x-ray diffraction analysis confirmed the epitaxy of the obtained films and the study of their normal state transport properties, removing the ambiguity regarding the truly conducting layer, allowed to highlight the presence of a robust hidden Fermi liquid charge transport in the low temperature properties of infinite layer electron doped cuprate superconductors. These results are in agreement with recent observations performed in other p  and n doped cuprate materials and point toward a general description of the superconducting and normal state properties in these compounds.

ABSTRACT

INTRODUCTION: Acute urinary retention (AUR) is a common reason for emergency consultation. It may be spontaneous or precipitated and affects both men and women. The purpose of this study was to determine the profile of men visiting emergency departments for an AUR. MATERIEL AND METHODS: A retrospective monocentric study including all men who consulted the emergency department between January 2014 and December 2016 for AUR was conducted. RESULTS: In 3 years, 731 patients were admitted for AUR (611 men and 120 women). The mean age was 71.6±14 years with a mean retention volume of 948±668mL drained for 96% of patients (n=584) through a bladder catheter and 4% (n=27) with a suprapubic catheter. Most patients had an urological (66%, n=104) or neurologic (40%, n=242) history and 23% (n=136) already had an episode of AUR. In 28% of cases (n=173), the globe was not painful. A majority of AUR were spontaneous, 53% (n=326) versus 46% (n=279) who were precipitated, secondary to a recent surgical procedure (<1 month) (15%, n=89), hematuria (9%, n=54), or male urinary tract infections (7%, n=42). Patients were treated externally in 71% (n=436), 25% (n=153) were hospitalized with significantly more comorbidities. CONCLUSION: Men consulting emergency for AUR are 72 years old, with a globe volume of 942mL. Thirty-three percent have a history of BPH, with a prostate treatment like alpha-blockers type. Almost all patients were treated with a bladder catheter and the majority was treated externally. LEVEL OF EVIDENCE: 4.

ABSTRACT

It is shown that the electron-phonon interaction at a conducting interface between a topological insulator thin film and a semiconductor substrate can be directly probed by means of high-resolution Brillouin light scattering (BLS). The observation of Kohn anomalies in the surface phonon dispersion curves of a 50 nm thick Bi2Te3 film on GaAs, besides demonstrating important electron-phonon coupling effects in the GHz frequency domain, shows that information on deep interface electrons can be obtained by tuning the penetration depth of optically-generated surface phonons so as to selectively probe the interface region, as in a sort of quantum sonar.

ABSTRACT

We present a simple two-stage vapour-solid synthesis method for the growth of bismuth chalcogenide (Bi2Te3, Bi2Se3) topological insulator nanowires/nanobelts by using Bi2Se3 or Bi2Te3 powders as source materials. During the first stage of the synthesis process nanoplateteles, serving as "catalysts" for further nanowire/nanobelt growth, are formed. At a second stage of the synthesis, the introduction of a N2 flow at 35 Torr pressure in the chamber induces the formation of free standing nanowires/nanobelts. The synthesised nanostructures demonstrate a layered single-crystalline structure and Bi : Se and Bi : Te ratios 40 : 60 at% for both Bi2Se3 and Bi2Te3 nanowires/nanobelts. The presence of Shubnikov de Haas oscillations in the longitudinal magneto-resistance of the nanowires/nanobelts and their specific angular dependence confirms the existence of 2D topological surface states in the synthesised nanostructures.

ABSTRACT

BACKGROUND: Borderline personality disorder (BPD) is characterized by a pervasive pattern of instability and impulsivity. There is a high prevalence of BPD patients among those admitted to the emergency department for suicide attempts. However, little empirical research exists to assist clinicians in deciding whether to hospitalize a suicidal patient. Some authors have argued that hospitalization does not prevent suicide and could actually harm these patients, thereby leading to psychosocial regression. Parasuicidal behaviors could be reinforced by the attention given during hospitalization. OBJECTIVE: Our purpose was to determine whether the hospitalization of suicidal patients who have a high risk of BPD after discharge from the emergency department is associated with a recurrence of suicidal behavior at 6months. METHOD: We designed a prospective study, acquiring patients from three emergency hospitals. The participants were suicidal subjects admitted for voluntary drug intoxication and were 18years of age or older. The participants completed the Personality Disorder Questionnaire (PDQ-4+) to assess BPD symptomatology. Information on the recurrence of suicidal behavior at 6months was obtained by interview of patients and the review of the charts from the 3 hospitals involved in the study. Other assessments included the BDI-13 (severity of depression), the Hopelessness Scale (hopelessness), the TAS-20 (alexythymia), the AUDIT (alcohol disorder) and the MINI (axis I disorders). RESULTS: A total of 606 subjects admitted for a suicide attempt participated in this study. A total of 320 (52.8 %) of the subjects completed the PDQ-4+. The sample was divided into three groups: participants at high risk of having at least one BPD (n=197), a group at high risk of having at least one non-BPD PD (n=84) and a group with low risk of having a PD (n=39). Hospitalization following an emergency was not associated with a recurrence of suicide attempts at 6months among patients at high risk of BPD. A logistical regression analysis showed pre-hospitalization antidepressant prescription to be associated with recidivism (OR=2.1, P=.037). CONCLUSION: Our exploratory study suggests that hospitalization may not increase suicide attempts among patients with BPD when the health organization does not include a specific device such as DBT.

ABSTRACT

Thiamine deficiency is recognized in varied parts of the world. In Asia, it remains an important public health problem where highly polished rice is the major staple food and where other primary dietary sources of thiamine are in short supply. Beriberi, or clinically apparent thiamine deficiency, may present a variety of syndromes including myocardial dysfunction or wet beriberi, dry beriberi with neurological symptoms, and the more severe form Shoshin beriberi with cardiac failure and lactic acidosis. Infantile thiamine deficiency is a very rare condition in developed countries today. It occurs mainly in breastfed infants of mothers who have inadequate intake of thiamine. Clinical symptoms in such infants include gastrointestinal symptoms, cardiac failure, and lactic acidosis. We report the case of a 10-week-old girl, admitted with diarrhea, vomiting, acidosis, and cardiac failure. After excluding other etiologies of cardiomyopathy, biochemical thiamine deficiency confirmed the diagnosis of beriberi in an infant of a thiamine-deficient mother from Reunion Island, a French island where recently, with Mayotte Island, epidemic cases of beriberi have been described. This case is important to highlight the manifestations in young infants and to alert physicians to the possibility of thiamine deficiency in developed countries.

ABSTRACT

AIM: To assess gender differences in characteristics, management, and hospital outcomes in patients participating in the French FAST-MI 2010 registry. POPULATION: Three thousand and seventy-nine patients hospitalised for ST-elevation (STEMI) or non-ST-elevation (NSTEMI) myocardial infarction in 213 French centres during a 1-month period at the end of 2010. RESULTS: Women account for 27% of the population and more frequently present with NSTEMI. They are 9 years older than men on average, although 25% of women with STEMI are less than 60 years of age. Management of STEMI is similar, after adjustment for baseline characteristics. However, fewer women are treated with primary percutaneous coronary angioplasty. In NSTEMI, although use of coronary angiography is similar, fewer women get treated with angioplasty. Most medications are used in a similar way in men and women, except thienopyridines, with fewer women receive prasugrel. After adjustment, in-hospital mortality is similar for men and women. CONCLUSION: Myocardial infarction is not specific to men: one out of four patients admitted for myocardial infarction is a woman. Initial management is rather similar for men and women, after taking into account differences in baseline characteristics. Percutaneous coronary angioplasty, however, remains less frequently used in women. In-hospital complications have become rarer and do not differ according to sex.

ABSTRACT

BACKGROUND: Repeated episode(s) of deliberate self-harm (RDSH) is a major risk factor for suicide. AIMS: To identify specific risk factors for RDSH among patients admitted following an episode of deliberate self-harm (DSH) through acute intoxication. METHODS: A prospective 6-month study was conducted with 184 patients (71% female) admitted to the emergency room (ER) as a result of self-poisoning (SP). RESULTS: Rate of RDSH stood at 18% after 6 months. The sociodemographic variables associated with repeated deliberate self-harm were to have no principal activity, consultation with a medical professional during the 6 months preceding the self-poisoning, and referral to psychiatric services upon release from the ER. The clinical variable associated with RDSH was alcohol addiction (OR=2.7; IC 95%=1.2-6.1, p<.05) as assessed at the time of the initial ER admission. CONCLUSIONS: When patients are initially admitted to the ER as a result of self-poisoning, it is important to evaluate specific factors, particularly alcohol use, that could subsequently lead to repeated deliberate self-harm. The goal is to improve the targeting and referral of patients toward structures that can best respond to their needs.

ABSTRACT

OBJECTIVE: To identify predictors of early TIMI 3 flow patency of the infarct-related artery after prehospital thrombolysis in patients with ST-segment elevation myocardial infarction (STEMI) using data from a "real-world" population, and to develop a nomogram for triaging patients to emergency angiography. DESIGN: Multicentre, observational, prospective, cohort study. SETTING: 79 Hospitals in France with a prehospital mobile intensive care unit and a coronary care unit with 24 h access to coronary angiography. PATIENTS: 997 Patients with STEMI. INTERVENTIONS: All patients received prehospital thrombolysis within 6 h of symptom onset and angiography was performed within 6 h of thrombolysis. MAIN OUTCOME MEASURES: Coronary patency (TIMI flow). RESULTS: The median age of the population was 59 years and the sample comprised 18% women. After multivariable logistic regression analysis, predictors of TIMI 3 flow in the infarct-related artery were current/previous smoking (odds ratio (OR) = 1.60, 95% confidence interval 1.15 to 2.22), < or =5 leads with ST-segment elevation before thrombolysis (OR = 1.59, 1.12 to 2.25), Killip class I (OR = 1.96, 1.05 to 3.67), chest pain relief (OR = 1.62, 1.17 to 2.25) and ST-segment resolution > or =70% (OR = 1.76, 1.29 to 2.38). A nomogram was developed to assess the probability of TIMI 3 flow, according to smoking status, number of leads with ST elevation before thrombolysis, Killip class, chest pain relief and ST-segment resolution. CONCLUSIONS: This study provides quantitative data for predicting success of prehospital thrombolysis. The nomogram is a simple tool for predicting likelihood of coronary patency, based on clinical and electrocardiographic data. It may help to identify patients who require emergency angiography and rescue percutaneous coronary intervention.

ABSTRACT

We present a micro-Raman study of a high quality Pr(0.5)Ca(0.5)MnO(3) single crystal and thin films on SrTiO(3) and LaAlO(3) substrates. Ten A(g) and seven B(2g) Raman-active modes (simplified symmetry: Pmma space group) have been observed and correlated to charge ordering around T(co) = 240 K and antiferromagnetic spin-orbital ordering at T(N)∼ 170 K. Our data reveal that coherent Jahn-Teller MnO(6) distortions prevail at T

ABSTRACT

The effectiveness of thrombolytics has been clearly demonstrated in more than half the cases in the large cohorts of patients selected for trials during the acute phase of myocardial infarction. At individual level, thrombolysis will clinically either succeed or fail so, for the medical team managing the patient, choice of treatment may be likened to a gamble which in the best of cases (most often) leads to an uncomplicated success and, in the worst of cases, failure worsened by a severe complication. OPTIMAL is a multidisciplinary and multicentre, prospective cohort study associating mobile medical teams and interventional cardiology units to test the hypothesis that the outcome of prehospital thrombolysis does not depend on chance alone but also varies according to demographic, etiological, clinical and logistic factors involved in the occurrence and management of myocardial infarction. The primary objective of this French study, conducted over one year on more than 800 subjects, is to identify the predictors of the results of prehospital thrombolysis from a very early angiographic evaluation. The results for this cohort may be useful for setting up appropriate management strategies for acute myocardial infarction, from the prehospital phase (thrombolysis or not) up to in-hospital orientation of the patients (angiography room or Intensive Care Unit) and to determine the most judicious time for coronary angiography. OPTIMAL is to date the largest prospective serie of prehospital thrombolysis evaluated by an early angiographic control.

ABSTRACT

The problem of pre-hospital management of acute coronary syndromes without ST elevation has not been extensively studied. The practitioner is faced with three simultaneous problems: suspecting the diagnosis, how to confirm the diagnosis to introduce appropriate, rapid and effective treatment, and which prognostic criteria to use to install aggressive therapy in high risk groups (anti GP lIb/IIIa, clopidogrel, angioplasty). TOSCANE is the first multicentre French registry which analyses the impact of the emergency ambulance serve in the management of these patients. There are two objectives: to gather epidemiological data about pre-hospital and hospital management by the emergency physician and the cardiologist, and to identify at an early stage criteria of "high risk" (HR) which, according to the recommendations of the European Society of Cardiology, justify using the most aggressive therapies. From April to September 2003, 797 patients with suspected acute coronary syndromes were enrolled by 36 French centre. Of these patients, 780 were managed successfully by the emergency ambulance service and hospital cardiological department with or without a "Cath Lab", and included for analysis. The diagnosis of acute coronary syndrome without ST elevation was rarely certain in the pre-hospital period. The lack of formal paraclinical features confirming the diagnosis was often a handicap for the emergency physician. Although the European recommendations are well observed in the cardiology departments, their application and adaptability should be improved in the pre-hospital period. TOSCANE showed that all invasive strategies preceded by platelet anti-aggregant therapy in the prehospital period administered to high risk patients, significantly reduced the mortality and morbidity at one month.

ABSTRACT

UNLABELLED: The aim of the ESTIM Midi-Pyrénées survey was to monitor the management of acute coronary syndrome with ST segment elevation by cardiologists and emergency departments in the Midi-Pyrénées region. Over a period of 2 years between June 2001 and June 2003, 1287 patients presenting with acute coronary syndrome within the first 24 hours were recruited prospectively. The initial management of these patients was undertaken either by a mobile medical team in the pre-hospital phase, or in a hospital emergency department, non-interventional cardiology department or an interventional cardiology department in 51.8%, 28.8%, 9.6% et 9.9% of cases respectively. Depending on these four modes of initial management, the median time for initial management was 1h30, 2h45, 4h30 et 4h respectively. Emergency coronary reperfusion was proposed in 89.6% of cases. Of the patients in whom reperfusion was attempted within the first 12 hours, 33.7% underwent pre-hospital thrombolysis (median delay of 1h48), 35.8% underwent thrombolysis in hospital (median delay 3h), and 30.4% underwent primary angioplasty (median delay 4h40). Thrombolysis was followed by angioplasty in 80% of cases. A combined approach with thrombolysis and angioplasty was applied in 41% of patients. At one month the rate of major cardiac events, death, and/or subsequent myocardial infarction was 12%. Multivariate analysis revealed that the only significant adverse prognostic features were: not offering reperfusion [Odds ratio (OR) 4, confidence interval (CI) 2.3-3.7] and age [OR 3.8, CI 2.3-6.2]. The method of reperfusion did not influence the subsequent outcome in this regional survey. CONCLUSION: pre-hospital management allows early revascularisation. In our region there was no significant prognostic difference between pre-hospital thrombolysis and primary angioplasty. It shows that the logistic and therapeutic potentials of prehospital care are not being sufficiently exploited.

ABSTRACT

BACKGROUND: Net whole-body and hepatic de novo lipogenesis could be more active in women than in men, but no comparison has been made between men and women in the two phases of the ovarian cycle after ingestion of a large carbohydrate meal. OBJECTIVE: We hypothesized that net whole-body de novo lipogenesis could be larger in women than men, and that glycogen and fat balance could be, respectively, lower and higher, following a large pasta meal ingested after rest or exercise. DESIGN: The metabolic response to a pasta meal (5 g dry weight/kg body mass) was studied in six men and six women (matched for age and BMI) in the follicular and luteal phases, following rest or exercise (90 min at 50% VO(2max)). Protein, glucose, and fat oxidation, and net whole-body de novo lipogenesis were computed for 10 h following ingestion of the meal using indirect respiratory calorimetry corrected for urea excretion. RESULTS: No net whole-body de novo lipogenesis was observed in any group in any situation (postrest and postexercise). When the meal was ingested following exercise, fat oxidation was significantly higher and glucose oxidation was significantly lower (P<0.05) than following the period of rest, and in a given experimental situation, the respective contributions of protein, fat, and glucose oxidation to the energy yield were similar in men and women in both phases of the cycle. CONCLUSIONS: The contribution of substrate oxidation to the energy expenditure as well as fat and glycogen balance, and the effect of a previous exercise period, were similar in men and women in both phases of the cycle following ingestion of the large carbohydrate meal.

ABSTRACT

BACKGROUND: Randomized trials comparing primary angioplasty and in-hospital fibrinolysis in acute myocardial infarction (AMI) have shown an advantage for primary angioplasty. The long-term follow-up of pre-hospital fibrinolysis followed by elective or rescue coronary angioplasty versus primary angioplasty is not well established after acute myocardial infarction. This study sought to assess the long-term clinical outcome of patients with AMI having either received pre-hospital fibrinolysis optimized by coronary angioplasty or primary angioplasty. METHODS: We conducted a retrospective analysis involving 318 patients who either underwent primary angioplasty ( n = 157) or received pre-hospital fibrinolysis followed by an angioplasty (rescue or elective) ( n = 161) within 6 hours of the onset of chest pain. RESULTS: The groups were similar regarding their baseline characteristics except for the ages. No difference was noted for in-hospital mortality (primary PTCA group: 2.48%, combined group: 2.54%; p = ns) with no increased risk of hemorrhage. The 3-year mortality was not significantly different in the two groups (9.7% vs. 4.9%; p = 0.15). Regarding major adverse cardiac events (29.5% vs. 37.5%; p = 0.23), reintervention (22.5% vs. 23.2%; p = 0.99) or target lesion revascularization (16.1% vs. 14.7%; p = 0.68), the groups were statistically similar. CONCLUSION: These data from real-life practice emphasize the safety and similar benefits on the long-term clinical outcome of AMI patients having undergone either pre-hospital fibrinolysis followed by angioplasty or primary angioplasty.
