Abstract
Several anterior and posterior methods are today available for stabilization of the cervical spine. Factors such as level and degree of instability, method of decompression, bone quality, length of fixation and safety factors influence the choice of method for a particular patient. The use of laminar hooks in the cervical spine has been restricted by fear of cord compression with the potential of tetraplegia. The aim of the present study was to assess the safety and determine the anatomical relation between hooks inserted in the cervical spinal canal and the dura and spinal cord. Thirteen cadavers from seven women and six men with no evidence of cervical spine disorder were included. The mean age was 81.3 years (range 65-101 years). The cervical spine was instrumented with cervical Compact Cotrel Dubousset hooks and rods. The effect of the hook on the dura was studied by myelography in nine cadavers. The deformation of the dural sac was quantified by measurement of the maximal width of the indentation of the contrast column at each level. A CT myelography scan was obtained in three cadavers. The ratio between the distance of maximal hook intrusion into the spinal canal and the canal diameter in the direction of the hook was calculated. The relation between inserted hooks and the spinal cord and dura was documented in a fresh cadaver studied with CT myelography. A hemilaminectomy was performed at all levels in three cadavers with direct visual inspection and photography of the hook sites before and after excision of the dura. A dural deformation of 2 mm or less, as observed by myelography, was found at four out of 77 (5%) hook sites. The deformation was caused by a supralaminar hook at C3, C6 and C7 and by an infralaminar hook at C6. The mean hook intrusion in the spinal canal, as observed on CT, was 27% (range 8-43) of the canal diameter. On visual inspection, 14 out of 18 hooks were in contact with the dura. After removal of the dura, two out of the 18 hooks in the same cadaver were in contact with the spinal cord. However, no deformation of the cord was observed. To our knowledge this is the first study systematically documenting the relation between hooks and the spinal cord in cadavers. In 95% of the hooks no deformation of the dural sac was observed and there was no evidence of spinal cord deformation. From an anatomical point of view, laminar hook instrumentation can be considered a safe procedure. The study shows, however, that hooks inserted in the cervical spine have a close anatomical relationship with the neuraxis, and at stenotic levels the use of other techniques is therefore recommended.

Abstract
In alcoholic patients, metabolic acidosis can be related to lactate acidosis associated with sepsis or thiamine deficiency, ketoacidosis, methanol or ethylene glycol poisoning. High resolution proton nuclear magnetic resonance (NMR) can be used to detect abnormal organic acid metabolites in urine or serum from patients with various metabolic disorders. In the present case, a 26-year-old patient was admitted for a coma associated with severe metabolic acidosis. Alcoholic ketoacidosis (AKA) was identified by urine proton NMR. Her metabolic disorders rapidly improved. Persisting associated neurological alteration was related to extrapontine myelinolysis as shown by imaging cerebral NMR.

Abstract
Myxoma is a benign tumour but which has redoubtable embolic complications. When situated in the left atrium, the emboli obstruct, in the majority of cases, the cerebral arteries, occasionally the visceral or coronary arteries, and, very rarely, the aorta. In this case, the authors report an atypical presentation with ischaemia of the lower half of the body, associated with pulmonary oedema and deep coma. The left atrial myxoma was responsible for complete and simultaneous obstruction of the internal carotid arteries and the infra-renal abdominal aorta. This report illustrates the fact that myxoma can be responsible for massive, life-threatening, embolisation.

Abstract
The authors report an exceptional and well-documented case of interruption of the retrohepatic segment of the inferior vena cava with an "azygos continuation", combined with absence of the portal vein. The only known combination of congenital anomalies of the inferior vena cava and the portal vein was that of an "azygos continuation" and a preduodenal portal vein. The double interruption, portal and inferior caval, may be associated with a disturbance of preferential flows induced by the left umbilical thrust. According to hemodynamic theory, the left umbilical flow is the determining factor in organogenesis of the portal vein and the retrohepatic segment of the inferior vena cava.

Abstract
MATERIAL 4 corpses (1 fresh, 3 formoled) without preliminary injection; age: 84 to 90. METHOD a front access enabled us to show the origin of the inferior rectal nerve from the pudendal plexus, its course across the Alcook canal and the ischiorectal fossa. Then a posterior transgluteal access showed the short intragluteal course across the "biligamentary tunnel" (between sacrospinal and sacrotuberal ligaments) of nerves and vessels related to the anus, in particular the inconstant Morestin's nerve. RESULTS AND CONCLUSION the compression of nerves causing perineal pain can occur at different places. Depending on the localisation of the origin and the course of the inferior rectal nerve (which change) in relation to the place of that compression, and also the existence or not of Morestin's nerve, the changing topography of these pains can be explained.

Abstract
The aim of this study was to define the anatomic characteristics of the principal arterial source of the atrioventricular node, known as the artery of the atrioventricular node. Forty hearts were studied by various anatomic and radiologic methods: dissection, injection-dissection, injection-corrosion and injection-radiography, but only 23 results were interpretable. The right coronary artery represented the commonest arterial source of the atrioventricular node (21/23 hearts) but numerous variations in the origin and topography of the nodal artery were found.

Abstract
In this study we investigated the interactions between capsular and acapsular strains of Cryptococcus neoformans and blood platelets. In vivo microscopic observation of blood samples from mice inoculated with C. neoformans yeast cells demonstrated that encapsulated and nonencapsulated yeast cells disappeared quickly from the bloodstream and that platelets were attached solely to yeast cells of the nonencapsulated strains. In vitro we observed that only the acapsular strains were susceptible to the fungicidal activity of thrombin-induced platelet microbicidal proteins.

Abstract
BACKGROUND In France, there are no guidelines available on withholding and withdrawal of life-sustaining treatments, and information on the frequency of such decisions is scarce. METHODS We undertook a prospective 2-month survey in 113, of a total of 220, intensive-care units (ICUs) in France to study the frequency of, and processes leading to, decisions to withhold and withdraw life-sustaining treatments. FINDINGS Life-supporting therapies were withheld or withdrawn in 807 (11.0%) of 7309 patients (withholding in 336 [4.6%] and withdrawal in 471 [6.4%], preceded in 358 by withholding). Of 1175 deaths in ICU, 628 (53%) were preceded by a decision to limit life-supporting therapies. Futility and poor expected quality of life were the most frequently cited reasons. Decisions were strongly correlated with the simplified acute physiological score, but an independent centre effect persisted after adjustment for this score. Decisions were mostly taken by all the ICU medical staff, with (54%) or without (34%) the nursing staff; however, a single physician made decisions in 12% of cases. The patient's family was involved in the decision-making process in 44% of cases. The patient's willingness to limit his or her own care was known in only 8% of the cases; only 0.5% of the patients were involved in decisions. INTERPRETATION Withholding and withdrawal of life-support therapies are widely practised in French ICUs, despite their prohibition by the French legislation. The lack of an official statement from French scientific bodies may explain several limitations on the various steps of the decision-making process.

Abstract
Anxiety is an affective response commonly experienced by persons after emotional and physical trauma, as well as associated with aversive medical treatments. The scientific information related to the conceptualization, assessment, and treatment of anxiety is limited. In order to develop a pilot protocol for anxiety management, nursing directors at 64 burn centers were surveyed. At 89% of the centers, anxiety measures were not used. Most of the teams assess informally through observation of patient (n=21), dialogue with patient (n=12), or both observation and dialogue with patient (n=15). Assessors of anxiety range in breadth from nurse only to the entire burn team, including pastoral care representatives and family. The class of medication most frequently endorsed in treating anxiety is the benzodiazipine, most often lorazepam (Ativan). A number of non-pharmacologic techniques are used to manage anxiety, e.g., muscle relaxation, breathing, imagery. Consideration should be given to assessing anxiety systematically, so knowledge can be gleaned and applied to conceptualization of symptom presentation and application of treatment resources.

Abstract
Sunflower downy mildew, caused by the fungus Plasmopara halstedii, is a potentially devastating disease. We produced two monoclonal antibodies (MAbs) (12C9 and 18E2) by immunizing mice with a partially purified extract of P. halstedii race 1. Both MAbs detected in enzyme-linked immunosorbent assay (ELISA) all races of P. halstedii present in France. No cross-reactions were observed with Plasmopara viticola or with other fungi commonly associated with sunflowers. Both MAbs recognized the same three fungal antigens with molecular masses of 68, 140, and 192 kDa. However, the epitopes on the fungal antigens were distinct and repetitive. Seed homogenates from infected plants were incubated in wells coated with MAb 18E2. This resulted in the trapping of P. halstedii antigens that were identified with biotinylated MAb 12C9. No reactions were seen with seed homogenates from healthy plants. Thus, our results suggest that these MAbs might be used to develop a sandwich ELISA detection system for P. halstedii in infected seeds.

Abstract
This study was designed to assess the frequency and risk factors for colonization with MRSA and A. baumanii in the intensive care unit, and to analyse the relationship between colonization and infection with MRSA or A. baumanii. During a 24-day survey period, colonization was studied weekly with nasal, throat and digit skin swabs; nosocomial infections were routinely monitored according to CDC recommendations. Clinical data and invasive procedures were registered during a one-year non-epidemic period; 103 ICU patients hospitalized for more than 7 days were prospectively included. We investigated acquired colonization and nosocomial infection with SAMR or A. baumanii for 87 patients not colonized by SAMR or A. baumanii on admission. The colonization acquisition rate was 56% for MRSA and 27% for A. baumanii. Infection incidence (cases per 1,000 patient-days) was 6.46 for MRSA and 1.61 for A. baumanii. On univariate analysis, acquired MRSA colonization was associated with longer ICU stays, longer mechanical ventilation and longer central venous catheterization. Multivariate analysis only showed an association with longer ICU stay. Acquired A. baumanii colonization was associated with SAPSII, longer mechanical ventilation, and longer central venous catheterization in univariate analysis. Multivariate analysis only showed an association with SAPSII and longer mechanical ventilation. In this study, SAMR or A. baumanii infections were not associated with colonization or clinical setting or invasive procedures.

Abstract
Very little information has been published about 2- and 3-year-old children who have experienced major burns. This study used a standardized instrument to measure the behavioral adjustment of these young burn survivors, and the results were compared with those of a nonclinical normative sample. Thirty-three pediatric burn survivors with 50%+/-28% total body surface area burns were evaluated 1.2+/-0.7 years postburn. Parental observations were assessed with the use of the Child Behavior Checklist for 2- and 3-Year-Olds, a 99-item standardized checklist designed to identify behavior problems. Forty of the questions are specific to 2- and 3-year-olds, and the scores of male and female children are not differentiated. The raw scores of the children with burns were statistically compared with the reported normative sample for this version of the Child Behavior Checklist. Pediatric burn survivors in this sample exhibited significantly more internalizing behaviors than the children in the normative group. Parents reported children who had been burned to be more depressed and to have more somatic complaints and sleep problems. Determining the relationship of behavior problems to posttrauma sequelae and preburn environmental factors would assist with the establishment of appropriate psychosocial interventions.

Abstract
PURPOSE Patients with systemic rheumatic diseases are rarely admitted in intensive care units and very few studies focusing on the prognosis of those patients have been published. METHODS Retrospective study over seven years in two intensive care units. RESULTS Among 33 patients with systemic disease diagnosed 90 +/- 133 months before admission in the intensive care unit, who were aged 50 +/- 21 years and represented a total of 39 stays in the intensive care unit, the main cause of admission was acute respiratory failure (33%). Mean simplified acute physiology score (SAPS II) was 47 +/- 22. Two-thirds of the patients were under mechanical ventilation. Infection was diagnosed in 33% of the cases and exacerbation of the systemic rheumatic disease in 26%. Nosocomial infection was found in 19 patients (49%). Ten patients died during their stay in the intensive care unit, six from infection, three from an exacerbation of the systemic rheumatic disease, one from an unidentified cause. CONCLUSION Even if severity scores of patients suffering from systemic diseases are higher at admission in intensive care units than those of other patients, there is no relevant reason to refuse critical care to these patients.

Abstract
The in vivo interactions of platelets with Candida species yeast cells were investigated in a murine model. Mice were injected intravenously via the lateral caudal vein, and blood drawn by periorbital puncture was collected in phosphate-buffered saline-formaldehyde to avoid in vitro platelet activation. The study of the clearance of blastoconidia of Candida albicans and Candida glabrata showed that these cells disappeared quickly from the bloodstream. Microscopic observation of blood samples, stained by Calcofluor white or May Grunwald Giemsa, demonstrated the rapid attachment of platelets to fungal elements of all the Candida spp. tested. The attachment of murine platelets to C. albicans cells, observed by scanning electron microscopy, revealed morphological changes. The platelets lost their discoid shape, generated pseudopodia, and flattened against the yeast cells. The reversibility of platelet binding to C. albicans by chelating agents suggests a cation-dependent link. In contrast, the fixation of C. glabrata and Candida tropicalis was not modified by chelating agents. The mechanisms involved in the in vivo adherence of platelets to Candida cells may therefore differ according to the species of Candida.

Abstract
Advances in medical management have dramatically decreased the mortality of children with massive burn injuries, which raises many questions about the expected quality of life for these young survivors. In this article, we address this issue by examining the functional and psychological adaptation of 41 young survivors with 88% mean total body surface area (TBSA) burns and 85% mean third degree TBSA burns. Patient scores were compared with normative data on standardized psychological measures of adjustment and on performance of age appropriate activities of daily living (ADL) skills. Thirty-three of the 41 patients (80%) were independent in basic ADL skills. Eighty-six percent of the patients who were aged 10 years and older were independent in advanced ADL skills. Patients with amputated fingers were significantly more dependent in ADL skills than those without amputations (P < .05). Mean psychosocial adjustment scores were within normal limits and were not significantly related to functional independence in ADL skills.

Abstract
Hydrophobic components of the germ tube of the dimorphic pathogenic fungus Candida albicans were used as immunogens to prepare monoclonal antibodies (MAbs). Among the resulting MAbs, one (MAb 16B1-F10) was shown by indirect immunofluorescence to be specific to the surface of the mycelium phase of the C. albicans and C. stellatoidea species. No labeling of any other genera and Candida species tested was observed, including C. dubliniensis, a newly described species which has many phenotypic similarities to C. albicans. This phase-specific epitope resides on a protein moiety. The molecular mass of the antigen released by Zymolyase digestion was determined by gel filtration and ranges from 25 to 166 kDa. The antigen was also shown to be highly hydrophobic. This anti-C. albicans cell wall surface-specific MAb may be a good candidate for use in tests for the rapid differentiation of the two closely related species C. albicans and C. dubliniensis.

Abstract
Although children with burn scars are reported to have positive self-concepts, social and sexual maturation can be expected to stimulate anxiety, depression and diminished self-esteem in adolescents with disfiguring scars. This study examines complex self-regard of adolescents with burn scars. The following were hypothesized: (1) adolescents with disfiguring burn scars would view themselves as less competent than unburned normative samples; (2) subjects' perceived competence would be incongruent with the importance ascribed to the domains of physical appearance and athletic competence and (3) depression/anxiety would correlate negatively with perceived competence. Subjects were 14 adolescents: 6 male and 8 female, 13-20 years old, at least 2 years post-burn injury (TBSA = 39% +/- 23%). All had scars in at least 2 of the following areas: head/face, neck, chest, hands, genitals. Each subject was administered the Harter Self Perception Profile, a standardized measure of self-competence and value in 8 domains plus a general competence measure. The subjects were also assessed for anxiety/depression by the Child Behavioral Checklist. Overall, adolescents in this sample exhibited a similar or higher degree of self-worth as compared to their peers. However, the athletic competence and physical appearance sub-domains of self-worth for the burn survivors were significantly lower as compared to the normative group. Half of the participants rated the importance of physical appearance to be higher than their level of personal competence in this area, making for distressing emotions. Mood was similar to the normative group and mood correlated significantly with self-worth.

Abstract
OBJECTIVE To determine the frequency and the eventual clinical characteristics of nosocomial sinusitis with anaerobic bacteria isolation in patients in the intensive care unit (ICU). DESIGN Retrospective study. SETTING A 12-bed medical ICU in a teaching hospital. PATIENTS 30 adult patients with documented nosocomial maxillary sinusitis. INTERVENTIONS None. MEASUREMENTS AND RESULTS Using appropriate microbiological techniques, 33 anaerobic bacterial strains were isolated in 18/30 patients (60 %) with nosocomial sinusitis. Anaerobic bacteria were associated with aerobic strains in 13 patients (72 %), whereas in 5 patients (28 %) only anaerobic strains were isolated in sinus puncture cultures. The most frequently isolated species were Prevotella sp. (n = 20, 60 %) and Fusobacterium nucleatum (n = 5, 15 %). The production of beta -lactamase was demonstrated in 13/27 gram-negative anaerobic bacteria. All patients in whom anaerobic bacteria were isolated from transnasal punctures had had a nasogastric tube. Patients in whom anaerobic bacteria were isolated more frequently had neurological disorders upon admission (p < 0.02). Ten patients (30 %) had nosocomial pneumonia, 8 of whom had at least one identical strain in both lung and sinus cultures, including 2 patients with anaerobic bacteria isolation. CONCLUSIONS Using appropriate microbiological techniques, anaerobic bacteria were frequently isolated in nosocomial sinusitis. If necessary, the empirical choice of antimicrobial therapy in patients with nosocomial sinusitis should take into account these results.

Abstract
PURPOSE Evaluate the influence of the anti-anaerobic antimicrobial therapy in the outcome of patients with nosocomial pneumonia. MATERIALS AND METHODS The population study included 53 intensive care unit patients with nosocomial pneumonia in whom, using a protected specimen brush, anaerobic bacteria were isolated, which were associated or not with aerobes. Current and empirical antibiotherapies were retrospectively analyzed, regarding their efficacy against anaerobic bacteria. Since it was debated, sensitivity to cefotaxime, ceftazidime, and ciprofloxacin was determined in 38 strains of Prevotella species. Outcome was evaluated 10 days after the day of protected specimen brushes. Improvement was defined as a decrease of Murray score or ventilator weaning. RESULTS The most frequently isolated bacteria were Prevotella species, which were more frequently resistant to cefotaxime (37%), ceftazidime (50%), and ciprofloxacine (32%) than usually reported in the literature. Sixty-six percent of these strains produced beta-lactamase. The effect of empirical anti-anaerobic antibiotherapy on the outcome at day 10 was evaluable in 39 patients. Twenty-nine patients were improved and 10 patients worsened. Interestingly, patients who had received well-adapted antibiotics against anaerobes had a better outcome after 10 days (P < .02). CONCLUSIONS This study suggests that specific antianaerobic therapy may be considered in the choice of empirical antibiotherapy in patients with nosocomial pneumonia.
