Abstract
Nocardia cyriacigeorgica is a recently characterized species within the genus of Nocardia. We report a brain abscess, following a primary pulmonary colonization, due to this species in a human immunodeficiency virus-infected patient. This case confirms that isolation of Nocardia in sputum is associated with a high risk of disseminated infection in immunocompromised patients.

Abstract
The objectives of the study were to describe the medical and social characteristics of patients consulting for the first time after diagnosis of HIV-infection and to compare the medical and social characteristics between French and migrant patients. From 1 January 2001 to 31 December 2002, all consecutive adults consulting for the first time for HIV infection in two HIV outpatient clinics located in the western suburb of Paris, agreed to an interview based on an administered questionnaire regarding their medical and socioeconomic characteristics. Of the 203 patients (98 women, 105 men), one-third (n=70) was of French nationality. Delay (+/-SD) in access to HIV outpatient clinic after diagnosis was shorter in migrant than in French patients, respectively 7.6+/-29.6 months (median=0.5, range=0 to 196.6) and 23.8+/-51.4 months (median=0.9, range=0 to 199.7); p=0.005. There was no significant difference in the medical characteristics between the two groups of patients on their first consultation. However, most of the migrants were living in very poor socio-economic conditions with minimal resources thus sometimes delaying initiation of HAART. The development of social facilities for HIV-positive migrants should be a public health priority.

Abstract
INTRODUCTION Simplification of combined antiretroviral therapy in HIV-infected patients is possible, but virological success can be compromised by the development or emergence of resistant viruses. CASE Worsening renal functioning in a patient under successful combination antiretroviral therapy resulted led to the replacement of indinavir by abacavir. Eight weeks later, his viral load rose and he developed a mutant virus resistant to all the nucleoside analogs. DISCUSSION Our case report illustrates the danger of streamlining combined antiretroviral therapy composed only of nucleoside analogs in patients already successfully treated with nucleoside analogs, by exposing them to the risk of the emergence of a mutant virus.

Abstract
Objective To study the prognosis of HIV-infected patients with virological failure after exposure to three classes of antiretroviral drugs (ARVs). Design Cohort study. Setting: French Hospital Database on HIV. Patients Patients previously exposed to at least two nucleoside reverse transcriptase inhibitors (NRTIs), two protease inhibitors and one non-NRTI, with viral load (VL) values of >5000 copies/ml after the exposure criteria were met and a new treatment initiated between 1998 and 2001 with VL >5000 copies/ml. Main outcome measures Risk of new AIDS-defining-events (ADEs) or death from first introduction of a drug never used before occurring between 1998 and 2001 defined as baseline. Results The main baseline characteristics of the 1092 patients were: previous ADE in 49% of cases, median CD4 cell count 181 μl, median VL 4.9 log10 copies/ml, median duration of ARV therapy 5.0 years and previous exposure to a median of nine ARVs. The crude progression rates were 20.1/100 patient-years among patients included in 1998, 15.1 in 1999, 11.1 in 2000 and 8.6 in 2001. After adjustment for baseline characteristics, the calendar year of inclusion was associated with the risk of clinical progression ( P<0.001). When the types of newly available drugs used at baseline or during follow-up were introduced into the model, year of inclusion was no longer associated with the risk of clinical progression ( P=0.42), while exposure to amprenavir/r, lopinavir/r, abacavir or tenofovir was associated with a lower risk. Conclusions The clinical prognosis of heavily pretreated patients experiencing virological failure improved between 1998 and 2001, mainly thanks to the use of newly available drugs with more favourable resistance profiles.

Abstract
INTRODUCTION AND METHOD Fifty-five patients (17 adults, 38 children) with meningococcal infection were admitted between 1986 and 2002 in a university hospital (500 beds). Fourteen of them (nine adults, five children) presented with an extra-meningeal infection. We compared adults and children presentations. RESULTS All adults had immunodeficiency. Septic locations were various (three bacteriemia, four pneumoniae, one infected ascitis, one cutaneous abscess). All patients received amoxicillin or third generation cephalosporin. Hospitalisation was prolonged (mean: 47 days). Seven patients required intensive care unit admission, and two of them died. All children (all were less than 36-month-old) presented with fever. Only one was immunodeficient (infected by human immunodeficiency virus). Neisseria meningitidis grew from blood in four, and in the throat for the remaining one. Hospitalisation was of short duration (mean: 4 days) and none of the children required intensive care unit. All the children recovered rapidly with antibiotics. CONCLUSION Outcome of extra-meningeal infection with N. meningitidis is different in adults and children. Adults present with immunodeficiency, infection is severe and patients present with various clinical features; children have a more homogeneous clinical presentation (fever) and outcome is excellent.

Abstract
The transplantation of porcine organs to humans could in the future be a solution to the worldwide organ shortage, but is to date still highly experimental. Further research on the potential effects of crossing the species barrier is essential before clinical application is acceptable. However, many crucial questions on efficacy and safety will ultimately only be answered by well designed and controlled solid organ xenotransplantation trials on humans. This paper is concerned with the question under which conditions, given the risks involved and the ethical issues raised, such clinical trials should be resumed. An alternative means of overcoming the safety and ethical issues is suggested: willed body donation for scientific research in the case of permanent vegetative status. This paper argues that conducting trials on such bodies with prior consent is preferable to the use of human subjects without lack of brain function.

Abstract
During an endoscopic third ventriculostomy (ETV) a sudden increase in intracranial pressure (ICP) may occur at any time. In the literature little attention has been paid to the early detection of such an increase. In particular the occurrence of a 'Cushing reflex' has not been discussed in this context. Therefore, we have now analysed retrospectively the anesthesia charts of 88 patients with obstructive hydrocephalus who had undergone ETV under general anesthesia. Monitoring included invasive blood pressure, electrocardiogram, end-expired carbon dioxide, pulse oximetry and heart rate. These variables were now evaluated before and after the introduction of the endoscope and during and after the occurrence of any change. In 67 patients the procedure had been uneventful. In 6 patients the occurrence of tachycardia and hypertension followed by bradycardia and hypertension was clearly the result of an increase in ICP, which we call a Cushing reflex. In his classical description of this pressure response Cushing reported the occurrence of hypertension, bradycardia and apnoea. However, many investigators have shown that beside systemic hypertension, both tachycardia and bradycardia are essential components of the Cushing reflex. Waiting for a persistent bradycardia to alert the surgeon during ETV can allow a fatal asystole.

Abstract
The treatment of chronic pain patients has changed over years. Anaesthesiologists treat pain patients, their skills in locoregional anaesthesia techniques and their pharmacological knowledge being a unique resource to reduce pain. However, the International Association for the Study of Pain provides more and more scientific evidence that chronic pain is a biopsychosocial event and that its diagnosis and treatment should be considered in a multidisciplinary frame. Nevertheless, in practice we can't deny the fact that there are several steps in the process in which the patient himself decides if he wants such an approach or not. The 'motivating' phase is a very important pretherapy and basic condition to start up a holistic pain treatment. Therefore, at the Ghent University Hospital Pain Clinic, we focused in a first step how to motivate our pain patients to take part in a multidisciplinary diagnostic examination, the second step is motivate them for an interdisciplinary treatment when it is indicated. We diagnose the four most important pain components: the sensory, myofacial, autonomic and psychosocial problems. The patient who is initially examined by the anaesthesiologist, will also be evaluated by the psychologist and the physician in rehabilitation medicine. By this way each component is mapped and a final (holistic) diagnosis can be made. In a weekly half-a-day meeting, the different specialists discuss the patients and put forward an interdisciplinary treatment plan. On several moments, the patients' treatment progress will be discussed and redirected if necessary. So, we hope to obtain an optimal result and avoid overtreatment and too invasive pain treatment.

Abstract
For ophthalmic surgery we have to deal with a wide range of different patient characteristics. We treat young healthy children, in some cases even neonates, but on the other hand we have debilitated aging patients with multiple concomitant diseases. Treatment of postoperative pain is imperative for inpatients, but is even more important for patients who are treated on an outpatient basis. There also is a wide range of different types of ophthalmic surgical procedures. The postoperative care after a cataract extraction is only seldom complicated by severe pain and is completely different of that after a vitrectomy with scleral buckling. More aggressive surgery as enucleation or evisceration of an eye often is a very stressful and painful procedure. We certainly have some excellent strategies to cope with postoperative pain. We can use topical anesthetics or non-steroidal anti-inflammatory medication. Regional anesthesia of the globe is extremely useful for anticipating on postoperative pain, especially when long-acting agents are used. We can administer analgesics by mouth or parenterally. Acetaminophen or paracetamol is widely used and can be supplemented with NSAIDs or opioids. Especially for children one has to use optimal doses of minor analgesics by an adequate route of administration in order to achieve a timely and efficient analgesia.

Abstract
BACKGROUND Cardiac catheterization of children with congenital heart disease is increasingly being performed under general anesthesia. Haemodynamic stability during anesthesia and fast and adequate recovery after the procedure is crucial in these patients. We performed a pilot study to evaluate hemodynamic stability when using remifentanil for anesthesia during cardiac catheterization. We also evaluated extubation times and recovery characteristics. METHODS In a randomized, prospective, double-blind study 30 children (aged 1.5-20 months) received a continuous infusion of either 0.2 (group 0.2) or 0.3 microg/kg/min remifentanil (group 0.3) as part of a balanced anesthesia with 0.6 MAC sevoflurane. Heart rate, noninvasive arterial blood pressure, end tidal CO2 and pulse oxymetry were monitored throughout the procedure. Extubation times were noted, and recovery from anesthesia was evaluated using Aldrete scores. RESULTS : Haemodynamic response to intubation was well blunted in both groups. No significant changes in hemodynamic variables were noted from induction of anesthesia until 10 min after intubation. From then on there was a decrease in HR and systolic arterial pressure, which remained significant throughout the procedure in both groups. Extubation times were similar in both groups: 7.3 min (2,1) in group 0.2 vs. 6.6 min (2,1) in group 0.3 (NS). The number of patients with an Aldrete score of nine or more was 14 (group 0.2) vs. 15 (group 0.3), 10 min after extubation (NS). CONCLUSION Both dose regimens of remifentanil provided stable hemodynamic conditions during anesthesia for cardiac catheterization of children with congenital heart disease and allowed for rapid and adequate recovery.

Abstract
BACKGROUND AND OBJECTIVE We reviewed retrospectively the anaesthetic management and perioperative course of eight right hepatectomies for living liver donation. METHODS After preoperative psychiatric evaluation, eight ASA I-II individuals donated the right lobe of their liver to a family member. A graft-recipient body weight ratio of 0.8-1.0% was required for patient selection. Indications for liver transplantation were: hepatitis C viral-related cirrhosis in six patients; combined hepatitis C and B viral cirrhosis in one patient; multifocal hepatocellular carcinoma--four lesions, involving both liver lobes--of hepatitis C viral-related cirrhosis in another patient. Indication for adult-to-adult living-donor liver transplantation was retained in the latter because of rapid deterioration of liver disease, rare recipient's blood group and extended, unresectable hepatocellular carcinoma. Hepatitis C viral-related cirrhosis was casually the primary indication for adult-to-adult living-donor liver transplantation in this group. The condition of the donated hepatic lobe was optimized by appropriate drug and perfusion management. Preoperative investigations included: blood tests (full cell count and film, thyroid function tests, pregnancy tests, full virological tests and bacteriological cultures, and immunological typing), chest radiograph, electrocardiogram plus Doppler cardiac ultrasound, spirometry, aminopyrine breath test, liver Doppler examination, magnetic resonance imaging, angiography and cholangiography and a volumetric study of the whole liver and the right lobe. Haemoglobin and lactate concentrations, liver function tests and international normalized ratio were measured before and after operation. The volume and weight of the resected right lobe was calculated. Anaesthesia was induced with propofol 300 mL h(-1) and sufentanil 0.3 microg kg(-1) intravenously; cisatracurium, 0.15 mg kg(-1), was given to facilitate tracheal intubation. Anaesthesia was maintained during normocapnic ventilation of the lungs with oxygen 40% in air, isoflurane 1-1.5 MAC and sufentanil. Routine anaesthetic monitoring included electrocardiography, pulse oximetry, invasive blood pressure, central venous pressure, urine output, state of neuromuscular blockade and core temperature. Periods of hypotension (<80% of the preoperative blood pressure) or haemodynamic instability (requiring inotropic or vasoactive support) were registered. Total blood loss and transfusion (homologous, autologous or cell-saver blood) requirements were measured; volume replacements were derived. RESULTS Data are presented as mean (range). There was no morbidity or mortality and no periods of intraoperative hypotension or haemodynamic instability. The operation time averaged 619 (525-780)min. Four donors were extubated in the operating room immediately after surgery; the others were extubated in the intensive care unit, where the mean extubation time was 16.3 (5-25)h after arrival. The estimated blood loss was 967 (550-1,600)mL. No homologous blood was administered; five donors received autologous blood, intraoperatively; three donors received a cell-saver blood transfusion. Intraoperative fluid replacement was with crystalloids, colloids and 4% albumin. Total urine output was 1,472 (700-3100)mL. Although intraoperative hypothermia occurred all subjects were normothermic at the end of operation. The pre- and immediately postoperative haemoglobin concentration averaged 13.6 (9.8-15.6) and 10.5 (6.9-13.0)gdL(-1), respectively. On the first postoperative day, the haemoglobin was 11.7 (8.4-15.1)gdL(-1). The donors' liver function tests were transiently elevated in the initial postoperative period. The intensive care unit discharge time was 2 (1-3) days. The hospital stay was 13 (7-17) days. There was no morbidity or mortality. CONCLUSIONS The study demonstrates that right-lobe living-donor surgery was well tolerated, without intraoperative hypotension or haemodynamic instability, without perioperative anaesthetic or surgical complications, and with an excellent general outcome.

Abstract
BACKGROUND AND OBJECTIVE Monitoring of neuromuscular blockade still often relies on clinical judgement. Moreover, there are substantial national differences in the use of agents to 'reverse' their effects. We investigated the recovery characteristics and incidence of postoperative residual curarization after cisatracurium and rocuronium infusions for long duration interventions without systematic antagonism. METHODS In 30 patients undergoing major surgery, we measured infusion dose requirements for rocuronium and cisatracurium during propofol anaesthesia. Infusions were discontinued at the beginning of surgical closure; spontaneous recovery of neuromuscular function was awaited in both groups. Neostigmine (50 microg kg(-1)) was administered only when a patient started to wake without a train-of-four ratio (TOF) of 0.9. RESULTS In the cisatracurium and rocuronium groups, four (27%) and one (7%) patients, respectively, had a TOF ratio > or = 0.9 at the end of surgery. The TOF ratio in each group at that time was 51 +/- 32% for cisatracurium and 47 +/- 31% for rocuronium (P = 0.78). Six patients (40%) in the cisatracurium group and seven (47%) in the rocuronium group required neostigmine. The TOF ratio at the time of reversal was 63 +/- 7% for cisatracurium and 40 +/- 19% for rocuronium (P = 0.01). The time interval between the end of surgery and a TOF ratio of 0.9 was 10 +/- 9 min for cisatracurium and 18 +/- 13 min for rocuronium (P = n.s.). CONCLUSIONS Patients receiving a cisatracurium or rocuronium infusion have a high incidence of postoperative residual curarization when the block is not antagonized. When 'reversal' is not attempted, cisatracurium seems to be safer than rocuronium.

Abstract
Focal adhesion kinase (FAK) plays an important role in integrin-mediated signal transduction pathways and its C-terminal noncatalytic domain Fak-related non-kinase (FRNK), which is autonomously expressed, acts as an inhibitor of FAK. A model has been proposed where FAK and FRNK compete for an essential common binding protein. A FRNK variant in which the direct interaction with v-Crk-associated tyrosine kinase substrate (CAS) was disturbed by point mutations still functioned as an inhibitor of FAK, suggesting that FRNK is unlikely to inhibit FAK by sequestering CAS. Deletion variants of FRNK within the region N-terminal to the focal adhesion targeting (FAT) sequence were still able to inhibit FAK function, indicating that this region is dispensable for the inhibitory effect of FRNK. Overexpression of a green fluorescent protein (GFP) fusion protein containing the FAT sequence delayed cell spreading and reduced FAK tyrosine phosphorylation. This indicates that the FAT sequence is the major inhibitory moiety within FRNK.

Abstract
Interventional Neuroradiology is a rather young department, that asks for an appropriate anesthesia management. This article highlights mainly the practical approach, with special directions for a thorough premedication, monitoring and patient positioning and extra attention to heparinisation and allergic reactions. Different anesthetic techniques are dealt with, namely conscious sedation and general anesthesia, as well as directives concerning potential complications.
