Angioedema associated with thrombolysis for ischemic stroke: analysis of a case-control study.

BACKGROUND: Bradykinin-mediated angioedema (AE) is a complication associated with thrombolysis for acute ischemic stroke. Risk factors are unknown and management is discussed. OBJECTIVES: To clarify risk factors associated with bradykinin-mediated AE after thrombolysis for acute ischemic stroke. METHODS: In a case-control study conducted at a French reference centre for bradykinin angiœdema, patients with thrombolysis for acute ischemic stroke and a diagnosis of bradykinin-mediated angiœdema, were compared to controls treated with thrombolysis treatment without angiœdema. RESULTS: Fifty-three thrombolysis-related AE were matched to 106 control subjects. The sites of attacks following thrombolysis for ischemic stroke mainly included tongue (34/53, 64%) and lips (26/53, 49%). The upper airways were involved in 37 (70%) cases. Three patients required mechanical ventilation. Patients with bradykinin-mediated angiœdema were more frequently women [33 (62%) vs. 44 (42%); P = 0.01], had higher frequency of prior ischemic stroke [12 (23%) vs. 9 (8%); P = 0.01], hypertension [46 (87%) vs. 70 (66%); P = 0.005], were more frequently treated with angiotensin-converting enzyme inhibitor [37 (70%) vs. 28 (26%); P < 0.001] and were more frequently hospitalized in intensive care medicine [ICU; 11 (21%) vs. 5 (5%); P = 0.004]. In multivariate analysis, factors associated with thrombolysis-related AE were female sex [odds ratio (OR), 3.04; 95% confident interval (CI), 1.32-7.01; P = 0.009] and treatment with angiotensin-converting enzyme inhibitors [(OR), 6.08; 95% (CI), 2.17-17.07; P < 0.001]. CONCLUSIONS: This case-control study points out angiotensin-converting enzyme inhibitors and female sex as risk factors of bradykinin AE associated with thrombolysis for ischemic stroke.

Schnitzler syndrome: validation and applicability of diagnostic criteria in real-life patients.

BACKGROUND: Schnitzler syndrome is characterized by an urticarial rash, a monoclonal gammopathy, and clinical, histological, and biological signs of neutrophil-mediated inflammation. The aim of this study was to assess the applicability and validity of the existing diagnostic criteria in real-life patients. METHODS: This multicentric study was conducted between 2009 and 2014 in 14 hospitals in which patients with Schnitzler syndrome or controls with related disorders were followed up. We compared the sensitivities and specificities and calculated the positive and negative predictive values of the Lipsker and of the Strasbourg criteria for the patients with Schnitzler syndrome and for the controls. We included 42 patients with Schnitzler syndrome, 12 with adult-onset Still's disease, 7 with cryopyrin-associated periodic disease, 9 with Waldenström disease, and 10 with chronic spontaneous urticaria. RESULTS: All patients with Schnitzler syndrome met the Lipsker criteria. According to the Strasbourg criteria, 34 patients had definite Schnitzler syndrome, five had probable Schnitzler syndrome, and three did not meet the criteria. One control met the Lipsker criteria and had probable Schnitzler syndrome according to the Strasbourg criteria. Sensitivity and specificity of the Lipsker criteria were 100% and 97%, respectively. For the Strasbourg criteria, sensitivity for definite and probable diagnosis was 81% and 93%, respectively, with a corresponding specificity of 100% and 97%. CONCLUSION: Diagnostic criteria currently in use to diagnose Schnitzler syndrome are reliable. More investigations must be done to attest their efficiency in patients with recent-onset manifestations.

A nasal visual field advantage in interocular competition.

When our eyes are confronted with discrepant images (yielding incompatible retinal inputs) interocular competition (IOC) is instigated. During IOC, one image temporarily dominates perception, while the other is suppressed. Many factors affecting IOC have been extensively examined. One factor that received surprisingly little attention, however, is the stimulus' visual hemifield (VHF) of origin. This is remarkable, as the VHF location of stimuli is known to affect visual performance in various contexts. Prompted by exploratory analyses, we examined five independent datasets of breaking continuous flash suppression experiments, to establish the VHF's role in IOC. We found that targets presented in nasal VHF locations broke through suppression much faster than targets in temporal VHF locations. Furthermore, we found that the magnitude of this nasal advantage depended on how strongly the targets were suppressed: the nasal advantage was larger for the recessive eye than for the dominant eye, and was larger in observers with a greater dominance imbalance between the eyes. Our findings suggest that the nasal advantage reported here originates in processing stages where IOC is resolved. Finally, we propose that a nasal advantage in IOC serves an adaptive role in human vision, as it can aid perception of partially occluded objects.

[Characteristics of patients admitted from emergency units in 18 internal medicine departments and organisation of these departments: A cross sectional study from SNFMI (SiFMI study group) in 2015]. / Caractéristiques des patients admis en médecine interne dans 18 hôpitaux français en aval des urgences et organisation de ces services : enquête transversale de la SNFMI (groupe d'étude SiFMI) en 2015.

INTRODUCTION: Patients admitted from emergency units represent a large portion of the population in internal medicine departments. The aim of this study is to identify characteristics of patients and organization of these departments. METHODS: Between June 29th and July 26th 2015, voluntary internal medicine departments from the SiFMI group prospectively filled anonymized internet forms to collect data of each patients admitted in their ward from emergency units, during seven consecutive days. RESULTS: Three hundred and sixty-five patients from emergency departments were admitted in 18 internal medicine inpatients departments, totalling 1100 beds and 33,530 annual stays, 56% of them for emergency units inpatients. Mean age was 68 years, 54% were women, mean Charlson score was 2.6 and 44% of the patients took at least three drugs. Main causes of hospitalization were infectious (29%) and neurological (17%) diseases. Mean length of stay was 9.2 days. The medical team was composed by a median value of 4,5 [2,75-6,25] senior full-time equivalents, 86% were internists. Each department except one received residents, two third of them were from general medicine. CONCLUSION: This study highlights a high organizational variability among internal medicine departments and patients, and sets internal medicine as a specialty with a great capacity to achieve an integrative/comprehensive management of patients and to offer a comprehensive basis for physicians in training.

[Ocular syphilis, a re-emergent pathology: Series of 12 patients in one Hospital, 2017]. / La syphilis oculaire, une pathologie ré-émergente : série de 12 patients au CHU de Marseille en 2017.

INTRODUCTION: Syphilis is a sexually transmitted disease. All organs might be affected, but ocular syphilis only occurs in 0.6 percent of patients. We collected all cases of ocular syphilis requiring hospitalization at the University Hospital Center (UHC) in Marseille in 2017. PATIENTS AND METHODS: This was a retrospective monocentric study. The diagnosis of ocular syphilis was based on the combination of ocular inflammation with a positive syphilitic serology. For each patient, sex, age, HIV status, ocular and extraocular symptoms, initial visual acuity, syphilis serology, cerebrospinal fluid (CSF) analysis if done, treatment and clinical response were collected. RESULTS: Ten men and two women, aged 28 to 86 years, were hospitalized. Two patients were HIV-positive. Ophtalmological lesions were heterogeneous the posterior structures were most affected. Anterior uveitis was isolated in one patient. Five patients had extraocular signs with cutaneous and/or mucosal involvement. No patient had neurological symptoms. Diagnosis of neurosyphilis through CSF analysis was definite for one patient, probable for 5 patients and ruled out for 2 patients. Six patients received treatment with penicillin G and six with ceftriaxone. Visual acuity improved in all cases. DISCUSSION: Ophtalmic cases of syphilis have become more frequent over the past few years in France. The diagnosis should be suspected in cases of eye inflammation even in the absence of favourable clinical presentation or anamnesis. Search for HIV co-infection should be systematic. Our study shows that ceftriaxone remains an effective alternative to penicillin G.

Meticillin-resistant Staphylococcus aureus contamination of healthcare workers' uniforms in long-term care facilities.

Meticillin-resistant Staphylococcus aureus (MRSA) and other multiply resistant bacteria are frequently isolated in long-term care facilities (LTCFs). This study evaluated the contamination of staff clothing in three LTCFs. Over 500 samples were taken from uniforms and their pockets and these samples showed a high level of MRSA contamination. Wearing plastic aprons and managing pocket contents improved the contamination rate. Our results highlight the continued importance of hand hygiene, since staff have frequent contact with their uniforms and could potentially contaminate their hands before care.

[Pain prevention with fixed 50% nitrous oxide-oxygen mixture during bone-marrow biopsy]. / Antalgie par mélange équimolaire d'oxygène et de protoxyde d'azote lors des biopsies ostéomédullaires.

PURPOSE: During bone-marrow biopsy, one third of patients score their pain as moderate or severe. Combination of analgesic and hypnotic is effective at reducing pain, but prolonged medical surveillance is necessary. The objective of the study was to assess the effectiveness and ease of use of the equimolar nitrous oxide-oxygen mixture (nitrous oxide), a short acting analgesic with little sedative effect, during bone-marrow biopsy. METHODS: As part of a non-controlled prospective observational study, patients undergoing a bone-marrow biopsy received nitrous oxide as an adjuvant to local anaesthesia. Facemask was self-maintained. A questionnaire was given after completion of the procedure to assess the pain (with a numerical-rating scale [RS] ranging from 0 to 10) as the main criterion and the ease of the procedure, the tolerance, and satisfaction, as secondary criteria. The physician noted adverse reactions. RESULTS: Nineteen women and 21 men were included. The median age was 51 years. Ninety percent of patients felt slight pain, less than 5 out of 10 on the RS. Only one patient had difficulty in keeping the mask. A patient experienced nausea and four presented a fleeting euphoria noticed by the physician. Ninety-five of patients wished to use nitrous oxide again should further bone-marrow examinations be necessary. CONCLUSION: Nitrous oxide is an effective analgesic when performing bone-marrow biopsies. Ten percent of patients feel a moderate to severe pain instead of one third. Despite some mild side effects, there is a very good appreciation by patients. Since this study, the authors routinely use nitrous oxide.

[Characteristics of giant cell arteritis patients under and over 75-years-old: A comparative study on 164 patients]. / Caractéristiques des patients de moins et de plus de 75 ans atteints d'artérite à cellules géantes : étude comparative de 164 patients.

PURPOSE: Giant cell arteritis (GCA) is the most common vasculitis of the elderly. In order to assess the impact of age at diagnosis, we compared the characteristics of patients of less than 75 years (<75 years), to those of the 75 years and over (≥75 years). PATIENTS AND METHODS: We conducted a retrospective study on 164 patients with GCA diagnosed from 2005 to 2017. All patients had at least 3/5 of the ACR criteria and had a CT-scan at diagnosis. The mean age was of 73±9.6 years. The age was<75 years for 84 patients (59 women) and≥75 years for 80 patients (53 women). RESULTS: Patients≥75 years had more cardiovascular underlying diseases (P=0.026), a higher rate of hypertension (P=0.005) and more ophthalmic complications (P=0.02). They had less large vessel involvement (P<0.001), showed lower biological inflammatory reaction and had a more frequently positive temporal artery histology (P=0.04). The oral initial dose of corticosteroids did not differ between the groups. Corticosteroids pulse therapy was more frequent in patients≥75 years (P=0.01). The frequency of anti-platelet agents use was similar in the two groups. Relapse rate, corticodependance and the rate of corticosteroids weaning were similar in both groups. CONCLUSION: Patients≥75 years at diagnosis of GCA were at lower risk of aortitis but were more likely to suffer from ophthalmic complications and to receive corticosteroid pulse therapy.

[Amiodarone-induced optic neuropathy: A rare side effect]. / Un effet indésirable rare de l'amiodarone : la neuropathie optique.

INTRODUCTION: The diagnosis of bilateral papilledema implies emergency medical care to look for intracranial hypertension and arteritic ischemic neuropathy. However, other causes must also be mentioned, including drugs. Too often underrated because of their usual benignity, drug side ophthalmological effects can be severe and are typically bilateral. CASE REPORT: An 80-year-old woman was hospitalized for bilateral papilledema, predominantly in the left eye, with lowered visual acuity. After ruling out intracranial hypertension, arteritic ischemic optic neuropathy, non-arteritic, and inflammatory bilateral papilledema, the diagnosis was toxic optic neuropathy. CONCLUSION: Bilateral edematous optic neuropathy is a known side effect of amiodarone, uncommon but to be known because of the large number of patients benefiting from this treatment.

Trends of methicillin-resistant Staphylococcus aureus (MRSA) and Enterobacteriaceae-producing extended-spectrum beta-lactamase (ESBLE) in eastern France: a three-year multi-centre incidence study.

The objective of this study was to describe trends for the years 2004 to 2006 in the incidence of methicillin-resistant Staphylococcus aureus (MRSA) and Enterobacteriaceae-producing extended-spectrum beta-lactamase (ESBLE) in a large hospital network (70 hospitals in eastern France). The incidence of MRSA per 1,000 patient-days decreased significantly from 0.55 in 2004 to 0.45 in 2006. This trend was observed in medicine and surgery units, whereas MRSA incidence was stable in intensive care, paediatric and obstetric units. The incidence of blood cultures positive for MRSA remained stable at 0.04 per 1,000 patient-days. Conversely, the incidence of ESBLE increased significantly from 0.04 in 2004 to 0.08 in 2006. This increase was caused by the spread of ESBLE-producing Escherichia coli. The mean consumption of alcohol-based gel and solution (ABS), expressed in litres per 1,000 patient-days, was 3.3 in 2002, 4.5 in 2003, 5.4 in 2004 and 6.4 in 2005. There was no association between the consumption of ABS and MRSA incidence. These findings suggest that the French recommendations for the control of multi-drug-resistant bacteria (MDRB) have been effective in reducing, or at least stabilising, the incidence of MRSA in an international context of general increase. However, the diffusion of ESBLE-producing E. coli is a matter of concern and should be carefully monitored.

[Impact of an evaluation of the professional practices on the relevance of proton pump inhibitors prescriptions pertinence at the hospital]. / Impact d'une évaluation des pratiques professionnelles sur la pertinence des prescriptions d'inhibiteurs de la pompe à protons à l'hôpital.

INTRODUCTION: Proton pump inhibitors (PPI) are widely prescribed for unrecognized indications, at high a dose and for a long duration, in spite of side effects and numerous drug interactions. In 2009, the HAS (French Health Authority) published recommendations of good prescription but the latter are poorly respected. In this context of over prescription and additional cost for the society, we performed a professional practice evaluation of on the model of the Deming wheel. The objective of this work was to optimize the relevance of the prescriptions of the IPP in two services of internal medicine and geriatrics through an evaluation of the professional practices. All PPI prescriptions introduced in outpatient visits or during hospitalization were analyzed. PATIENTS AND METHODS: Data collection was prospective, over two periods of 2 months and included 163 (first phase), then 139 patients (second phase). An assessment grid of PPI prescriptions was completed by physicians regarding the active substance, the dose, the duration and the indication of the prescription. The relevance of the prescription corresponded to PPI with a conformed indication and duration and to the prescriptions no recommended stopped. Following the first period of data collection, information was given to medical students and physicians on the relevance of their prescriptions with regard to the current recommendations and informative flyers were offered with the aim of improving the practices before the second period of evaluation (second phase). RESULTS: During the first phase, only 25% of the pre-hospital prescriptions and 33% of the hospital prescriptions respected the HAS recommendations. The main indication of the PPI was the prevention of peptic ulcers in a context of associated drug estimated at risk. An improvement of the global relevance of prescription was observed after awareness of the physicians: 26% relevance during the first phase and 60% in the second one (P<0.012). During the second phase, the part of PPI prescriptions introduced at hospital decreased from 33 to 17% and the discontinuation of the not corresponding prescriptions increased from 6 to 33%, with an additional information given to the general practitioner (P<0.001). However, during the second phase, 33% of the prescriptions introduced in hospitalization were always not corresponding and 61% of the not corresponding prescriptions begun in outpatient visits were always pursued on discharge, probably due to the lack of sufficient information to stop the prescription. CONCLUSION: Our study underlines the frequent disrespect of the indications in the prescription of PPI. Interestingly, a professional practices evaluation improved the relevance of the prescriptions with a more frequent withdrawal of the not corresponding exposure and a decrease in global not corresponding prescriptions. Our study suggests that it is crucial to regularly inform physicians on the good prescription of PPI. Patient information focused on the indications and the limited duration of PPI prescription, potentially severe side effects of chronic exposure and on the risk of drug interactions also remains necessary in order to facilitate the stop of the exposure and restrict self-medication.

[Respiratory tract infections in institutions for elderly people: the GROG Géronto-Alsace, strategy of surveillance and alert]. / Infections respiratoires aiguës dans les collectivités de personnes âgées: le GROG Géronto-Alsace, une démarche expérimentale de surveillance et d'alerte.

OBJECTIVE: Outbreaks of respiratory tract infections are common in institutions for elderly people. The objective of our study was the implementation of a network including 11 institutions to determine the frequency of such outbreaks. Using the collected data, criteria and alert levels are defined to assess the level of respiratory tract infections and develop appropriate interventions. METHODOLOGY: Prospective surveillance for respiratory tract infection was conducted in 11 institutions in Alsace for 2 years. Clinical definitions were used to identify the infected residents. For the identification of influenza virus, nasopharyngeal samples using swabs were obtained and rapid tests (immunoassay) were performed. RESULTS: During the surveillance, outbreaks were identified in institutions. The same observations occurred in all institutions at the same time. Alert levels were defined in order to characterize the outbreak period and to improve detection and control of outbreaks of respiratory tract infections. CONCLUSION: Ours findings show the importance of an adequate surveillance and networks improve the impact of such measures.

[Anaerobic deep abscesses with unusual location: report of 5 cases]. / Abcès profonds à germes anaérobies de localisation inhabituelle: à propos de cinq cas.

OBJECTIVE: Anaerobic deep abscesses are rare and may have unusual location leading to severe outcome due to delayed diagnosis and treatment. In order to improve their diagnosis, we report and analyse 5 new cases. METHODS: Patients were seen from 1999 to 2003 in a single department of internal medicine of the university hospital of Marseille. RESULTS: Five new cases were diagnosed consisting in 3 females and 2 males with a medium age of 56,8 years, with unusual location in 4 cases: epidural (2), psoas (1) and sub-diaphragmatic (1) or circumstances in one case of pulmonary abscess unrelated to inhalation. Predisposing conditions thought to compromise resistance to infection were found in all cases: social poverty (4/5), alcoholism (3/5), smoking (4/5), teeth and periodontal disease (4/5), neoplasia (2/5), iatrogenic disease (2/5). Symptoms were insidious (5/5) and unspecific but were always related to the abscess location. Abscesses were frequently found distant from the initial focus of infection because of frequent hematogenous spread (4/5). Drainage of the collection led to bacterial identification in all cases (4/4), although blood cultures could be positive (3/5) and helpful in one case in which drainage was not possible (1/5). The isolated organisms always corresponded to the suspected initial focus (oropharynx 4/5 and digestive 1/5). Finally, combination of surgical drainage and double prolonged antibiotherapy (penicillin+metronidazole) was the elected treatment. CONCLUSION: Since hematogenous diffusion is frequent, anaerobic infection should be suspected in any case of deep abscess affecting patients with predisposing conditions such as poverty, severe teeth disease or iatrogenic procedure.

Epidemiological data on Staphylococcus aureus strains producing synergohymenotropic toxins.

DNA hybridisation of 309 consecutive Staphylococcus aureus clinical isolates with oligonucleotide probes specific for genes encoding Panton-Valentine leucocidin (luk-PV) and gamma-haemolysin (hlg) revealed that 99% of randomly selected strains carried the hlg locus whereas only 2% harboured the luk-PV as well as the hlg loci. Only 1% of the strains did not possess either gene. In a clinical prospective study of independent S. aureus strains, 58 Panton-Valentine leucocidin (PVL)-producing isolates were shown to be responsible for primary skin infections, mainly furuncles (86%). Phage susceptibility patterns and pulsed field gel electrophoresis (PFGE) profiles of DNA were shown to be polymorphic epidemiological markers of PVL-producing strains. In eight patients with recurrent furuncles, the PVL-producing strains isolated either from furuncles or from the anterior nares were considered to be identical in each based upon phage sensitivity profiles or PFGE patterns.

[Quantitative bacteriological evaluation of a method for skin disinfection in blood donors]. / Evaluation bactériologique quantitative d'une méthode de désinfection cutanée chez les donneurs de sang.

Skin disinfection at the site of venipuncture is a critical point in every blood transfusion collection procedure, as it contributes to ensure the bacterial safety of transfusion. Quantitative and qualitative analysis of bacteria present in the antecubital fossae before and after skin disinfection may be one method of assessing the anti-bacterial efficiency of disinfection. Swab culture systems and contact plates are the two techniques usually employed for this purpose. A washing and swabbing technique was used to quantify bacteria before and skin disinfection of the antecubital fossae in blood donors. This contra-placebo study was carried out on 32 donors, each of whom served as his own control, with a random choice of test arm and opposing control arm. Bacterial counts were determined in the antecubital fossae without skin disinfection (control, n = 32) and after a 3 step skin preparation procedure (cleaning, wiping, disinfection) using placebo (distilled water, n = 16) or an antiseptic product (mixture of chlorexidine, benzalkonium chloride and benzylic alcohol, n = 16). The absence of a statistical difference in bacterial counts between the right and left antecubital fossae without disinfection was controlled in a preliminary study of 20 subjects. Mean bacterial counts were 25,000/cm2 and 27,400/cm2 respectively for aerobic and anaerobic bacteria before disinfection, with a wide variation in results between individuals. When using placebo, preparation of the venipuncture site by the 3 step method (cleaning, wiping, disinfection) resulted in a non significant mean reduction of 0.56 log in aerobic and anaerobic bacteria. Using the antiseptic product, the same method resulted in a significant mean reduction of 1.8 and 1.7 log respectively in aerobic (p = 0.015) and anaerobic flora (p = 0.005). On an average, 2,750 aerobic bacteria/cm2 and 2,910 anaerobic bacteria/cm2 remained after disinfection, while qualitative analysis showed that disinfection suppressed the transitory flora in all cases but left part of the resident flora in 12/16 cases. These findings are comparable to those of other studies carried out to evaluate this kind of technique for the disinfection of operation sites. In comparison with other techniques classically employed for this type of evaluation (swab systems or contact plates), the method used in this study was the advantage of allowing the quantification of the reduction in bacteria. Hence this method could be employed for comparative assessment of skin disinfection techniques with the aim of improving their anti-bacterial efficiency and could also make possible the definition of a minimum bacterial count (resident flora) to be obtained in all cases after disinfection.

[Thymoma and hypogammaglobulinemia. Good's syndrome: apropos of a case and review of the literature]. / Thymome et hypogammaglobulinémie, le syndrome de Good: à propos d'un cas et revue de la littérature.

INTRODUCTION: Good's syndrome is defined as the association of thymoma, hypogammaglobulinemia, and repetitive bronchopulmonary infections. We report one case and review the clinical and immunological features of this syndrome. EXEGESIS: We describe the case of a 67-year-old man who presented with both severe bronchopulmonary infection resistant to antibiotherapy and thymoma. Definite diagnosis was based on the existence of hypogammaglobulinemia. Treatment with intravenous immunoglobulins led to positive outcome. CONCLUSION: Good's syndrome occurs in only 5% of parathymic diseases. To prevent further bronchial tube destruction and pulmonary surgery, it must be diagnosed and treated early.

[Cold agglutinins, clinical presentation and significance; retrospective analysis of 58 patients]. / Agglutinines froides, circonstances de découverte chez l'adulte et signification en pratique clinique: analyse rétrospective à propos de 58 patients.

PURPOSE: To describe clinical, biological characteristics and associated diseases of cold agglutinins in adults. METHODS: Retrospective study in a single department of internal medicine from 1997 to 2002. The inclusion criteria were a positive direct Coombs test and a positive research for cold-reactive autoantibodies. We recorded for each patient: clinical presentation at onset and during follow-up, biological parameters of haemolysis, biological characteristics of the cold agglutinin and associated diseases. RESULTS: Fifty-eight patients (34 females, 24 males), with medium age of 58.8 were included in the study. Clinical presentation was highly variable between acute life-threatening haemolysis and absence of symptoms. Results of direct antiglobulin test were C3 (74%), IgG + C3 (22.4%), IgG (3.4%). Titer, thermal amplitude, strength and specificity of Coombs test were correlated, in all cases except 6, with cold agglutinin haemolytic activity. In 77.6% of cases cold agglutinin was secondary; related to: autoimmune disorders (n = 19), lymphoproliferative disorders (n = 11) and infections (n = 10). CONCLUSION: Clinical presentation of cold agglutinin is highly variable and not always related to the biological characteristics of the bound antibody (titer, thermal amplitude, specificity). In our single center study, diseases associated with cold agglutinin were various with the highest frequency of auto-immune disorders. Our study underlined also the high frequency of lymphoproliferative disorders and justifies a close follow-up of these patients. Finally, we reported a high frequency of hepatitis C virus infection among the infectious aetiologies.

[Shrinking lung syndrome and systemic auto-immune disease]. / Le syndrome des poumons rétractés et les maladies auto-immunes.

INTRODUCTION: Shrinking lung syndrome usually manifest in dyspnea, decreased lung volume associated with elevated diaphragm. It reports with systemic autoimmune disease and physiopathological mechanism is controversial. EXEGESIS: We report three shrinking lung syndrome observations in which two cases were diagnosed at the time to onset of autoimmune disease. The three patients were treated with corticosteroid, two of them necessitated theophylline. Review of the literature highlight 60 cases and permit to discuss physiopathological mechanisms which remain uncertain. Diaphragmatic dysfunction (because of myositis or neuropathy) represented by abnormal transdiaphragmatic pressures is actually discussed. CONCLUSION: Shrinking lung syndrome is rare but must be considered in patient with autoimmune disease and dyspnea. The diagnosis can be difficult because of clinical, pathological and functional features which are controversial. The optimum treatment is unknown.

[Central nervous tuberculosis in patients non-VIH: seven case reports]. / Tuberculose cérébroméningée chez l'adulte séronégatif pour le VIH: à propos de 7 cas.

PURPOSE: Tuberculosis involving the central nervous system (CNS) is rarely observed in non immuno-compromised hosts. We report herin the various clinical, biological and radiological manifestations observed in 7 patients with CNS tuberculosis. METHODS: Clinical and biological records of 7 patients with CNS tuberculosis were retrospectively studied. All patients had encephalic CT-scan and MRI in the course of the disease. RESULTS: 5 women and 2 men with a mean age of 38.4 years initially initially presented with headache (n = 6), fever (n = 5), meningeal irritation (n = 3), localizing neurological signs (n = 1). Lumbar punction revealed lymphocytic meningitis (n = 6/7). Mycobacterium tuberculosis or bovis was isolated in 3 patients only. Cerebral tomodensitography or magnetic resonance imaging were initially normal in most of cases (n = 4/7), but discovered in the course of disease basilar meningitis (n = 6), hydrocephalus (n = 6), abcess or tuberculoma (n = 4). In all the patients, initiation of the treatment was complicated by clinical and/or biological deterioration, called paradoxal reaction, leading in all cases to glucocorticoid adjunction, with various final results. Indeed, 4 patients developed neurological sequelae. No patient died. CONCLUSION: CNS tuberculosis is a rare disease in non immunocompromised patients whose diagnostic may be difficult due to the absence of specific clinical symptoms, negative initial radiological examination, as well as delayed and often negative bacterial isolation. Paradoxal reaction appeared to be frequent despite specific antibiotherapy and underlines the beneficial effects of addictive corticosteroids.
