Abstract
The optimal amount of systemic corticosteroids to be used in acute severe asthma remains an unresolved issue. In this double-blind, randomized study we compared two doses of methylprednisolone (1 vs 6 mg.kg-1 q.d.) in asthmatics presenting with an acute severe asthma attack, unresponsive to an intensive beta 2-agonist regimen administered during a run-in period. Concurrent therapy, including oxygen, inhaled and intravenous salbutamol, and aminophylline was strictly standardized. The response was assessed by serial bedside spirometry. The primary outcome measurement was forced expiratory volume in one second (FEV1) (expressed as percentage of predicted values) at 24 and 44 h. The trial was designed in order to achieve a statistical power of 90%. Twenty three patients were included in the low-dose group and 24 in the high-dose group. Both groups were comparable in terms of demographic profiles, history of asthma, and severity of the current attack. Improvement in pulmonary function was similar in both groups. At 44 h, the mean (+/- SD) FEV1 values were 53 +/- 22 and 45 +/- 14% in the low and in the high-dose group respectively (NS). We conclude that high dose systemic corticosteroids offer no further benefit over low-doses in the treatment of severe acute asthma.

Abstract
Quality of care assessment is based on three main prerequisites: to describe precisely patients or case-mix, to measure the level of care, to evaluate the outcomes and finally to consider the relationships between these parameters. Indicators to measure the level of nurses' workload have been developed from different concepts and methodologies: The range of nurses' activities is very wide, such as cares achieved in the presence of patient, cares achieved after medical prescription or specific nurse cares, administrative tasks, research activities, etc. Indicators may take into account a more or less important part of this field, but most of them are usually focused on patient's care. The value of each parameter may be a calculated coefficient or a time unit. If one considers the time as the best unit to measure the intensity of work, it is also an underlying concept to differentiate the actual time, obtained by timing, from the required time, necessary to achieve correctly the action. In the same way, required cares are also the best to consider. Indeed measuring required time for required cares is necessary to reach quality aim. The nurses' workload may be directly calculated with a specific indicator or indirectly estimated from a severity or disability scoring system. The selection of the indicator depends of the purpose of the evaluation process. If the question is to improve and develop quality of care and professional practices, the indicator has to take into account the required cares. The PRN system (Project de Recherche en Nursing) developed in Canada is probably the reference indicator. However this score is complex and cannot be daily used.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Interpretation of the protected specimen brush (PSB) technique is based on quantitative bacterial cultures (QC), which unfortunately requires at least 24 h. We prospectively compared the diagnostic value of direct examination (DE) and QC of PSB specimens in 75 patients with suspected pneumonia. We also determined the optimal technique for DE. QC was performed using the serial dilution technique. From the original suspension, two cytospin slides were obtained and stained by the May-Grünwald Giemsa (MGG) and the Gram method for DE. If the prescreening on the MGG-stained slide was positive, the morphology and the Gram staining of the organisms were assessed on the Gram-stained slide. Using the 10(3) colony forming units (cfu.ml-1) threshold for defining PSB as positive or negative, DE had a sensitivity of 85% and a specificity of 94%. In a parallel in vitro study, 18 pairs of PSB specimens were collected from respiratory secretions inoculated with S. aureus. From each pair, one brush was processed as described above and the other was smeared on a glass slide prior to performance of QC. Using direct smear instead of cytocentrifuged preparation, slightly but significantly affected QC. Direct examination of cytospin slides is highly predictive of quantitative bacterial culture results, and provides rapid information regarding the Gram-stain morphology of the causative organisms. It may therefore guide initial therapy.

Abstract
The aim of this study was to verify whether a relationship exists between neuroleptic malignant syndrome (NMS) and anaesthetic-induced malignant hyperthermia (MH) or not. The in vitro halothane-caffeine tests were performed on muscle tissue obtained from 32 patients with documented NMS episodes. The diagnosis of NMS relied on Levenson's criteria. The results, expressed in accordance with the criteria of the European MH Group, defined 29 subjects as MH non-susceptible. Three patients were classified as MH equivocal. These findings demonstrate the lack of any link between NMS and MH. Therefore, patients with a history of NMS are not likely to be at risk of developing MH and special measures against MH are not required for anaesthesia in these patients.

Abstract
OBJECTIVE To develop and validate a new Simplified Acute Physiology Score, the SAPS II, from a large sample of surgical and medical patients, and to provide a method to convert the score to a probability of hospital mortality. DESIGN AND SETTING The SAPS II and the probability of hospital mortality were developed and validated using data from consecutive admissions to 137 adult medical and/or surgical intensive care units in 12 countries. PATIENTS The 13,152 patients were randomly divided into developmental (65%) and validation (35%) samples. Patients younger than 18 years, burn patients, coronary care patients, and cardiac surgery patients were excluded. OUTCOME MEASURE Vital status at hospital discharge. RESULTS The SAPS II includes only 17 variables: 12 physiology variables, age, type of admission (scheduled surgical, unscheduled surgical, or medical), and three underlying disease variables (acquired immunodeficiency syndrome, metastatic cancer, and hematologic malignancy). Goodness-of-fit tests indicated that the model performed well in the developmental sample and validated well in an independent sample of patients (P = .883 and P = .104 in the developmental and validation samples, respectively). The area under the receiver operating characteristic curve was 0.88 in the developmental sample and 0.86 in the validation sample. CONCLUSION The SAPS II, based on a large international sample of patients, provides an estimate of the risk of death without having to specify a primary diagnosis. This is a starting point for future evaluation of the efficiency of intensive care units.

Abstract
The objectives of the study were to determine the agreement between the protected specimen brush technique (PSB) with quantitative cultures and endotracheal aspirates (EA) with quantitative cultures when using increasing interpretative cutoff points and to investigate the respective operating characteristics for the diagnosis of pneumonia of PSB and EA when using quantitative cultures. Consecutive sampling of respiratory secretions using these two techniques was conducted in the respiratory intensive care units in 52 mechanically ventilated patients with clinical and radiologic suspicion of pneumonia. Quantitative bacterial cultures of PSB and EA samples were obtained. The 10(6) cfu/ml cutoff point was the most accurate diagnostic threshold for the EA technique. When using this threshold, there was a high level of agreement (84.6%) between PSB and EA results. Among the few discrepancies, the EA result was always indicative of pneumonia, whereas the PSB result was nonindicative, thus permitting us to classify correctly five patients in whom pneumonia would have been erroneously excluded on the basis of the sole result of PSB. Conversely, there was no case where the PSB result was indicative of pneumonia when the EA result (at the 10(6) cfu/ml level) was not. The operating characteristics of the PSB technique for the diagnosis of pneumonia were in accordance with previously published studies. The operating characteristics of the EA technique (when taking the 10(6) cfu/ml of respiratory secretions as the interpretative cutoff point) compared favorably with those of the PSB technique. Diagnostic accuracy rates were similar. The specificity of EA was somewhat lower (83 versus 96%), but the sensitivity was higher (82 versus 64%).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Many inorganic species, such as calcium, phosphate and magnesium, are in equilibrium between the liquid and colloidal phases of milk and hence are of importance with respect to the coagulation properties of milk. Capillary ion electrophoresis makes possible the determination of anions and cations in less than 6 min. The soluble phase of milk was obtained by ultrafiltration and samples had to be diluted 250-fold before analysis. Cold storage increased soluble calcium and phosphate concentrations, and warm-up of the milk restored the initial ionic equilibria. More drastic heat treatments (80-90 degrees C) caused precipitation of tricalcium phosphate and calcium citrate.

Abstract
The protected specimen brush (PSB) with quantitative cultures is one of the most reliable techniques for assessing pneumonia in mechanically ventilated (MV) patients. The need to select a certain lung segment for bronchoscopic sampling is still debated. We investigated whether the results of PSB specimens collected within an area radiographically involved with pneumonia (inv-PSB) differed from the results of PSB specimens collected within a lung area without radiographic abnormalities (non-inv-PSB) in 39 MV patients with suspected pneumonia. The comparison of bacterial titers of inv-PSB and non-inv-PSB cultures did not disclose significant differences. Agreement regarding the diagnosis of pneumonia according to recommended diagnostic threshold was observed in 34 of 39 patients (87.1 percent). These results which are in accordance with the pathophysiology of ventilator-associated pneumonia and histologic studies do not support the need to select a certain lung segment for bronchoscopic sampling in most MV patients with suspected pneumonia.

Abstract
The repeatability (i.e., the variation in repeated measurements of the same quantity) of the protected specimen brush (PSB) with quantitative cultures was assessed in 22 consecutive mechanically ventilated (MV) patients with suspected nosocomial pneumonia. Five PSB samples were collected in the same lung area during the same bronchoscopic procedure and processed for bacteriologic identification and quantitative culture. A laboratory control was also performed in order to assess the in vitro repeatability of the quantitative culture technique. The five PSB always recovered the same microorganisms, indicating a 100% qualitative repeatability for the PSB. Conversely, the quantitative repeatability was somewhat lower since in 59% of the patients the quantitative results varied by more than one log10, which is the minimal precision affordable with quantitative cultures. The distinction between presence or absence of infection based on the 10(3) cfu/ml recommended diagnostic threshold was, however, only moderately affected by the variability of the quantitative results since only three of 22 patients (13.6%) displayed results spread out on each side of the 10(3) cfu/ml break point. Intrasubject variability of quantitative results was not explained by problems with the quantitative culture technique, which proved excellent repeatability in the laboratory. This study indicated that, although the PSB technique with quantitative cultures displays an acceptable level of repeatability, caution is advisable when interpreting PSB results in critically ill patients with suspected pneumonia, especially if one refers to the 10(3) cfu/ml recommended diagnostic threshold and if a decision to treat or to abstain from treating is to be made.

Abstract
The objective of the present study was to investigate the long-term prognosis of near-fatal asthma. A retrospective cohort study design was used. Cases were defined as any asthmatic individual requiring mechanical ventilation for the first time for an asthma exacerbation between January 1, 1983 and December 31, 1988. The consecutive sample of patients was drawn from four study sites, specifically four intensive care units (ICU), based in a large urban area (1 million inhabitants). These four ICU total approximately 5,000 admissions per year and are the referral centers for more than 95% of patients requiring respiratory intensive care in the area. Data collection was obtained by questionnaires addressed to the patients and to their attending physicians and was completed by telephone calls if necessary. A total of 147 patients entered the study. The long-term outcome could be evaluated in all but two patients. The follow-up period ranged from 1 to 75 months. In-hospital mortality was 16.5%. Among the 121 patients discharged from the ICU, 18 subsequently died, 17 of whom died from a new attack of asthma. Post-hospitalization mortality was 10.1% (95% CI, 5.9 to 16.8%) after 1 yr, 14.4% (CI, 9 to 22.3%) after 3 yr, and 22.6% (CI, 12.7 to 36.8%) after 6 yr. Nearly two-thirds (61.5%) of these secondary deaths occurred within the year following discharge from the ICU. Smoking was associated with a higher in-hospital mortality, as well as with a higher posthospitalization mortality. Age was also independently associated with a higher posthospitalization mortality. It is noteworthy that the secondary deaths were mostly observed in patients over 40 yr of age.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The case is reported of a 49-year-old chronic alcoholic woman, who presented with severe pulmonary arterial hypertension (PAH) mimicking as an acute abdomen. She was admitted with right-sided hypochondrial abdominal pain and hepatomegaly, with a moderate jaundice. On admission to intensive care unit, she had an arterial blood pressure of 110/70 mmHg, a heart rate of 100 b.min-1, and a respiratory rate of 36 c.min-1. An electrocardiogram showed sinus rhythm and right-sided heart failure. Whilst breathing 6 l.min-1 oxygen, her arterial blood gases were: PaO2 47 mmHg PaCO2 29 mmHg. Severe PAH was confirmed by measuring her mean pulmonary arterial pressure, which was 46 mmHg, whilst her pulmonary wedge pressure was 7 mmHg. Hepatic function was also altered: total bilirubin 41 mumol.l-1, alkaline phosphatase 145 UI.l-1 and gamma glutamyl transferase 1 340 UI.l-1. She developed arterial hypotension, which did not respond to increasing doses of isoproterenol. She died on the third day. Necropsy confirmed the diagnosis of primary PAH, with acute "cardiac liver".

Abstract
Hemodynamic effects and gas exchange were studied in twenty COPD patients undergoing mechanical ventilation before and 30 and 60 minutes after an intravenous administration of 1 mg/kg enoximone. Enoximone decreased significantly pulmonary arterial pressure and pulmonary vascular resistances without significantly decrease of systemic vascular resistances 60 minutes after a slight dose of 1 mg/kg. Right ventricular ejection fraction increased; O2 arterial pressure, CO2 arterial pressure, intrapulmonary shunt remained unchanged. We concluded that enoximone induced pulmonary vasodilation in patients with decompensated COPD and increased right ventricular function without deleterious effects in gas exchange.

Abstract
The neuroleptic malignant syndrome (NMS) is an uncommon but dangerous complication of treatment with neuroleptic drugs. A primary defect in skeletal muscle has been suggested in view of similarities in the clinical presentations of NMS and anaesthetic-induced malignant hyperthermia (MH). The in vitro halothane-caffeine contracture tests are the most reliable method of identifying individuals susceptible to MH. The aim of this study was to define if a relationship exists between NMS and MH susceptibility. Hence, the in vitro halothane and caffeine contracture tests were performed on muscle tissue obtained from eight NMS, ten MH-susceptible and ten control patients. The results, which are expressed in accordance with the criteria of the European MH Group, defined the eight NMS subjects as MH non-susceptible. The response to halothane and caffeine exposure of skeletal muscle from NMS and control subjects was the same and significantly different from that of muscle from patients susceptible to MH. Furthermore, muscle from subjects in NMS and control group responded similarly to increasing concentrations of chlorpromazine. These results do not point towards an association between NMS and MH.

Abstract
Nosocomial bronchopulmonary infections are common and severe complications, particularly in intensive care units. The high incidence of pneumonia is related to multiple factors such as underlying disease, acute respiratory failure, nutritional disorders, depressed mental status and the frequent need tracheal intubation. The most frequent cause of respiratory tract infection is aspiration of oropharyngeal secretions. In hospitalized patients, there is usually an oropharyngeal colonization with Gram-negative bacteria. Prevention of nosocomial bronchopulmonary infections requires close attention to the patient's environment, proper techniques, handwashing and decontamination of respiratory equipment.

Abstract
Two non specific severity scoring systems, acute physiological score (APS) and simplified acute physiological score (SAPS) are compared with a specific index (Sc) in an evaluation of 96 ICU patients with "serious" bacterial pneumonia. The three scores were measured during the first 24 h following ICU admission. There is a good correlation between APS, SAPS or Sc. Accuracy and efficiency of the non specific scoring indexes and Sc are similar. There is no statistical difference in sensitivity, specificity, positive and negative predictive values, receiver operating characteristic curves of the three indexes. Simple and reliable non specific index such as SAPS, valid for a variety of pathologies, can be used in an evaluation of mortality and comparative studies of groups of patients with serious bacterial pneumonia.

Abstract
The indications for hyperbaric oxygen therapy (HBO) in the treatment of acute carbon monoxide (CO) poisoning are discussed far too little in the literature. Depending on the author reasons for referral to a hyperbaric center include the carboxyhemoglobin level, change in state of consciousness or neurological abnormalities. In our opinion, HBO should be used on much wider indications than is usual, not only because of the rapid relief from symptoms it provides but mainly because it may prevent severe delayed sequelae. During a period of 9 months 230 patients with CO poisoning were admitted to our intensive care unit; 203 were treated with HBO and 27 with normobaric oxygen. Our indications for HBO treatment were: coma, pathological neurological findings or loss of consciousness during CO exposure irrespective of normal clinical findings on admission. Four patients died and the others were discharged 12 hours to 25 days after the incident. Seven patients had minor neurological problems within two weeks of discharge and which disappeared within one month. Two patients were re-hospitalized for neuropsychiatric sequelae and recovered in 3 and 6 months respectively. Neither the clinical status upon admission nor COHb predicted the outcome of the poisoning. Referral to a HBO center should be considered when: --the patient is comatose --there are abnormal clinical findings --patients have been unconsciousness during exposure, irrespective of whether they are conscious on admission and have normal clinical status.

Abstract
The natural history of conduction disorders in infarction and their prognostic significance are now well known and determine the choice of treatment. In the acute phase of inferior infarction without bundle branch block, temporary pacing is only indicated in cases with poor clinical tolerance or with a bradycardia of less than 50. Prophylactic pacing, on the other hand, appears to be necessary in cases of anterior infarction with branch block, at least in the high risk group in which the block is recent and bifascicular. In this case, the pacemaker is only permanent in cases of high degree atrio-ventricular block in the acute phase. The subsequent prognosis of anterior infarction with branch block and without high degree atrio-ventricular block in the acute phase carries a high incidence of sudden death. Primary delayed ventricular fibrillation during the first eight weeks seems to be the cause for this sudden death. Prolonged hospital surveillance of these patients would appear to be indicated.

Abstract
285 patients affected by carbon monoxide poisoning were admitted in our intensive care unit over a period of two years (from july 1980 to july 1982). 18 patients had a pulmonary edema (P.E.). The occurrence of P.E. was more frequent when coma was grade 2, 3 or 4 (p less than 10(-3]. The acute physiologic score (weighting of physiologic measurements) as proposed by Knauss is higher in patients with P.E. (p less than 10(-2]. However death is never due to P.E.; about 54 patients with coma, 5 died; death is related to neurologic aggravation. Neurologic sequelae are not related to the occurrence of P.E. but to a delay in hyperbaric oxygen therapy. These date show that prognosis of carbon monoxide poisoning is related to neurological status and is not influenced by the occurrence of P.E. when correctly treated and when hyperbaric oxygen therapy is early realized.
