Abstract
BACKGROUND Debate continues regarding the usefulness and benefits of wide prescription of antibiotics in patients hospitalized with coronavirus disease 2019 (COVID-19). METHODS All patients hospitalized in the Infectious Diseases Department, Dijon University Hospital, Dijon, France between 27 February and 30 April 2020 with confirmed COVID-19 were included in this study. Clinical, biological and radiological data were collected, as well as treatment and outcome data. An unfavourable outcome was defined as death or transfer to the intensive care unit. Patient characteristics and outcomes were compared between patients who did and did not receive antibiotic therapy using propensity score matching. FINDINGS Among the 222 patients included, 174 (78%) received antibiotic therapy. The univariate analysis showed that patients who received antibiotic therapy were significantly older, frailer and had more severe presentation at admission compared with patients who did not receive antibiotic therapy. Unfavourable outcomes were more common in patients who received antibiotic therapy [hazard ratio (HR) 2.94, 95% confidence interval (CI) 1.07-8.11; P = 0.04]. Multi-variate analysis and propensity score matching indicated that antibiotic therapy was not significantly associated with outcome (HR 1.612, 95% CI 0.562-4.629; P = 0.37). CONCLUSION Antibiotics were frequently prescribed in this study and this was associated with more severe presentation at admission. However, antibiotic therapy was not associated with outcome, even after adjustment. In line with recent publications, such data support the need to streamline antibiotic therapy in patients with COVID-19.

Abstract
BACKGROUND The emergence of Zika virus (ZIKV) represents a threat with consequences on maternal and children's health. We aimed to assess the clinical and epidemiological characteristics of pregnant women returning from ZIKV affected areas, and the effects of maternal ZIKV infection on birth outcomes and children's health. METHODS This was a hospital-based prospective observational study conducted at the Hospital Clínic of Barcelona and Hospital Sant Joan de Déu, Barcelona, Spain, from January 2016 to February 2020. RESULTS One hundred and ninety-five pregnant women who had travelled to ZIKV affected areas during pregnancy were recruited. Four women (2.1%) had a confirmed ZIKV infection, 40 women (20.5%) a probable infection, and 151 (77.4%) were negative for ZIKV. Among the ZIKV confirmed cases, a pregnant woman suffered a miscarriage, highly plausible to be associated with ZIKV infection. Brain cysts and microcalcifications were detected in 7% of fetuses or infants from women with confirmed or probable ZIKV infection. Neurodevelopmental delay in the language function was found in 33.3% out of the 21 children evaluated. CONCLUSIONS These findings contribute to the understanding of ZIKV prevalence estimates, and the impact of maternal ZIKV infection on pregnancy outcomes and children's health. Results highlight the importance of long-term surveillance in pregnant travellers and their children.

Abstract
Microbiological analyses were conducted on wild eels from the L'Albufera Lake (Spain). A total of 174 individuals were collected in two surveys (i.e. year 2008 and autumn-winter 2014) among those caught by local fishermen into the lagoon. The prevalence of Shewanella putrefaciens group was 1.7% in 2008 and rose above 32% in 2014. It was due to an outbreak of shewanellosis that presented a morbidity rate of 64%. S. putrefaciens group strains were isolated as pure cultures from the sick eels that showed white ulcers surrounded by a reddish inflammation, damage of the mouth, extensive skin discoloration, exophthalmia, ascites and bad odour. The S. putrefaciens group was recovered from freshwater samples taken at the L'Albufera system, along autumn-winter 2015. Its counts significantly increased in freshwater parallel to hypoxia and temperature rising. Shewanellae strains were identified as S. putrefaciens and S. xiamenensis by 16S rRNA gene sequencing. These isolates recovered from sick eels or freshwater were virulent for European eel by IP challenge (LD50 106 CFU g-1 body weight). They also caused 30-38% cumulative mortality, in European eels challenged by a 2-h bath (107 CFU mL-1 ). These results suggest that shewanellosis could be transmitted through water highlighting the fact that hypoxic conditions increase this bacterium levels in water.

Abstract
MALDI mass spectrometry imaging is able to simultaneously determine the spatial distribution of hundreds of molecules directly from tissue sections, without labeling and without prior knowledge. Ultra-high mass resolution measurements based on Fourier-transform mass spectrometry have been utilized to resolve isobaric lipids, metabolites and tryptic peptides. Here we demonstrate the potential of 15T MALDI-FTICR MSI for molecular pathology in a mouse model of high-grade glioma. The high mass accuracy and resolving power of high field FTICR MSI enabled tumor specific proteoforms, and tumor-specific proteins with overlapping and isobaric isotopic distributions to be clearly resolved. The protein ions detected by MALDI MSI were assigned to proteins identified by region-specific microproteomics (0.8 mm2 regions isolated using laser capture microdissection) on the basis of exact mass and isotopic distribution. These label free quantitative experiments also confirmed the protein expression changes observed by MALDI MSI and revealed changes in key metabolic proteins, which were supported by in-situ metabolite MALDI MSI.

Abstract
Aeromonas infections are rare in Europe and often related to traveller's diarrhoea. A total of 185 Aeromonas isolates from river water, fish and clinical sources, recovered during a 1-year period, were used to investigate the disease spectrum and impact of multidrug-resistant (MDR) strains. They were all identified by biochemical tests and 25% of them were also identified by sequencing of the 16S rRNA gene. The minimum inhibitory concentrations (MICs) of 21 antimicrobials were determined for all isolates by broth microdilution/E-strips methods, and susceptibility was assessed according to the Clinical and Laboratory Standards Institute (CLSI). Strains pathogenicity was determined by using Swiss Webster mice as the animal model. Aeromonas diseases had an incidence of around 20 cases/million inhabitants in the metropolitan area of Valencia (Spain). Acute gastroenteritis in children with no history of travel abroad was the main pathology. These cases were related to A. caviae, A. veronii biovar sobria, A. hydrophila and A. dhakensis. A significant incidence of A. caviae in humans was found, while the other species were equally present in clinical and environmental origins. A. jandaei, A. bestiarum and A. media had mainly an environmental distribution. The prevalence of MDR Aeromonas was maximal in clinical samples, and resistance phenotypes were significantly related to this source. 7.2% of environmental Aeromonas was resistant to at least five drugs; most of them were moderately virulent for mice and, in addition, belonged to clinically significant species. The present study demonstrates a diseases spectrum similar to that reported in tropical countries, and also that pathogenic and heavily MDR Aeromonas are present in environmental reservoirs. MDR Aeromonas from any source analysed were susceptible to aztreonam, netilmicin, cefotaxime, ceftazidime, cefepime and fluoroquinolones.

Abstract
A virological analysis was conducted on wild eels from the Albufera Lake (Spain). A total of 179 individuals at different growth stages were collected in two different surveys (2004 and 2008). Presence of anguillid herpesvirus (AngHV-1), aquabirnavirus and betanodavirus was confirmed by PCR procedures in both surveys, although the number of detections was clearly higher in 2008 (83% of the eels analysed resulted positive for virus presence). AngHV-1 was the viral agent most frequently detected, followed by aquabirnaviruses. Betanodaviruses were detected by the first time in wild eels, and although the detections were only made by nested PCR, high percentage of positives were achieved. In addition, in 2008, seven aquabirnaviruses were isolated. Phylogenetic analysis performed using partial sequences of both genomic segments of aquabirnaviruses indicated that the seven isolates could be typed as WB (genogroup I) on the basis of segment A sequences, but when segment B was used six of them clustered with C1 strain (genogroup V) and one was typed as Ab (genogroup II). These results indicate natural reassortment between different strains of aquabirnaviruses in the eels. Although betanodaviruses were not isolated in cell culture, the analysis of the sequence of the nested PCR product indicated that they clustered with SJNNV genotype. The diversity of viral agents and the high level of viral detections suggest that viral infections may play a more prominent role in the decline of the European eel than initially thought.

Abstract
Olive pollen is one of the most important causes of seasonal respiratory allergy in Mediterranean countries, where this tree is intensely cultivated. Besides this, some cases of contact dermatitis and food allergy to the olive fruit and olive oil have been also described. Several scientific studies dealing with olive allergens has been reported, being the information available about them constantly increasing. Up to date, twelve allergens have been identified in olive pollen while just one allergen has been identified in olive fruit. This review article describes considerations about allergen extraction and production, also describing the different methodologies employed in the physicochemical and immunological characterization of olive allergens. Finally, a revision of the most relevant studies in the analysis of both olive pollen and olive fruit allergens is carried out.

Abstract
A retrospective study was conducted in a private infertility centre to evaluate the rate of complications in a large oocyte donation programme. A total of 4052 oocyte retrievals were performed between January 2001 and October 2007. Altogether, 1238 cycles (30.6%) were stimulated with the use of gonadotrophin-releasing hormone (GnRH) agonists and in 2814 cycles (69.4%) the GnRH antagonist protocol was used. The GnRH antagonist treated cycles were triggered with human chorionic gonadotrophin (HCG) or a GnRH agonist in 1295 and 1519 cycles, respectively. Complications related to oocyte retrieval occurred in 17 patients (0.42%) (intra-abdominal bleeding: n = 14, severe pain: n = 2, ovarian torsion: n = 1). Fourteen of these were hospitalized (0.35%) and six donors (0.15%) required surgical intervention. Pelvic infections, injury to pelvic structures or anaesthesiological complications were not observed in this series. Moderate/severe ovarian hyperstimulation syndrome (OHSS) occurred in 22 donors; 11 required hospital admission and 11 were managed on an outpatient basis. All cases were related to HCG triggering (0.87%). Serious complications related to oocyte retrieval occurred at a low rate in healthy young donors. The risk of OHSS can be substantially reduced by specific stimulation protocols, which include GnRH agonist triggering. Prospective oocyte donors should be adequately counselled about the risks related to egg donation.

Abstract
AIMS To determine the incidence of multiple antibiotic-resistant strains of the emergent human pathogens Legionella pneumophila, Pseudomonas aeruginosa and mesophilic Aeromonas species among those isolated from water reservoirs and industrial cooling systems. METHODS AND RESULTS Water from four natural water reservoirs and four industrial cooling towers was sampled for 1 year period. The total heterotrophs, mesophilic Aeromonas, Pseudomonas spp. and Legionella spp. counts were performed as recommended by standard procedures, and the sensitivity of the isolates to 27 antibiotics was tested. A total of 117 Aeromonas, 60 P. aeruginosa and 15 L. pneumophila strains were isolated and identified by means of biochemical tests and DNA probes. 46.4% of Aeromonas, and 100% of P. aeruginosa isolates presented multiple resistance. Legionella pneumophila strains were generally sensitive to the drugs used. CONCLUSIONS Antibiotic-resistant pathogenic bacteria belonging to P. aeruginosa and mesophilic Aeromonas species are common in natural aquatic environments. Thus, the risk of waterborne diseases owing to domestic and industrial uses of freshwater should be re-examined from the increase of bacterial resistance point of view. SIGNIFICANCE AND IMPACT OF THE STUDY These data confirm the emergence of bacteria resistant to antibiotics in aquatic environments.

Abstract
OBJECTIVE Our goal in this study was to evaluate by means of MRI the clinical significance of tendon integrity, muscle fatty degeneration, and muscle atrophy in surgically repaired massive rotator cuff tears and to correlate these and other prognostic factors with intraoperative and clinical findings. MATERIALS AND METHODS Twenty-eight surgically proven massive rotator cuff tears were retrospectively included in the study. Twenty-two patients underwent complete repair, and six patients underwent partial repair. Preoperative and postoperative clinical assessment was performed by using the University of California at Los Angeles score. Preoperative and postoperative MRI studies were evaluated for the presence and extent of rotator cuff tear and for the degree of fatty degeneration and atrophy of the rotator cuff muscles. RESULTS At a mean 44.4 months' follow-up, 20 patients (71.4%) had a favorable result. A total of 25 patients (89.2%) showed postoperative full-thickness rotator cuff tear, 19 of which were reruptures. A sagittal preoperative rotator cuff tear of less than or equal to 34 mm showed a specificity of 100% for predicting a favorable outcome. A coronal postoperative rotator cuff tear of less than or equal to 34 mm showed a specificity of 85.7% and a positive predictive value of 92.9% for predicting a favorable outcome. A postoperative fatty degeneration of infraspinatus muscle less than or equal to 2 had a specificity of 87.5% and a positive predictive value of 90.9% for predicting a favorable outcome. CONCLUSION Open repair of massive rotator cuff tears may reach a favorable outcome in a significant proportion of patients, despite a high rate of recurrent or residual tears. Oblique coronal sizes of the recurrent or residual tear of less than or equal to 34 mm and postoperative fatty degenerations of infraspinatus muscle of less than or equal to 2 may allow a favorable outcome.

Abstract
This prospective study assessed the postoperative analgesic effect of intra-articular ketorolac, morphine, and bupivacaine during arthroscopic outpatient partial meniscectomy. Group 1 patients (n=20) received postoperative injection of 60 mg intra-articular ketorolac, group 2 patients (n=20) 10 cc intra-articular bupivacaine 0.25%, group 3 patients (n=20) 1 mg intra-articular morphine diluted in 10 cc saline, and group 4 patients (n=20, controls) only 10 cc saline. We evaluated the postoperative analgesic effect (period measured from the end of the surgery until further analgesia was demanded), the level of postoperative pain (by visual analog scale 1, 2, 3, 12, and 24 h after surgery), and the need for additional pain medication (during the first 24 h after surgery). The best analgesic effect was in patients treated with intra-articular ketorolac, and this was statistically significant in: postoperative analgesic effect and the need for additional pain medication immediately after surgery, and after 24 h. No complications were found related to the intra-articular treatment. We conclude that 60 mg intra-articular ketorolac provides better analgesic effect than 10 cc intra-articular bupivacaine 0.25% or 1 mg intra-articular morphine.

Abstract
AIMS To determine the haemolysins and proteases excreted by the virulent strain EO63 of Aeromonas hydrophila grown in complex media and to then fractionate and characterize them, in particular those with elastolytic activity. METHODS AND RESULTS The amount of haemolytic and proteolytic activity in EO63 culture supernatants was dependent on the culture media used. In all media, haemolysins appeared during the phase of active growth and haemolytic activity decreased quickly thereafter, as previously described for aerolysin. In contrast, proteases were mainly released during the stationary phase. Serine protease activity in EO63 culture supernatants was four times greater than that caused by metalloproteases. Two main proteases were partially purified from EO63 culture supernatants by isoelectrophoresis: a serine protease (68 kDa) active against casein; a mixture of different protein bands (60, 44 and 31 kDa) representing a thermostable metalloprotease active against elastin and casein. This metallo-elastase was also inhibited by dithiothreitol and showed a pH optimum of 8.0. Both exoenzymes were toxic for eels at LD50 doses of 1.1 and 3.5 microg (g fish)(-1), respectively. CONCLUSIONS A serine caseinase and a metallo-elastase may play a role in the pathogenicity of EO63 for eels. These toxins are excreted in vitro by EO63 in the ratio of 4:1 during the stationary phase of growth. Strain EO63 also produced beta-haemolysins in vitro which could correspond to aerolysin. SIGNIFICANCE AND IMPACT OF THE STUDY This is the first report on the purification of a metallo-elastase excreted by a wild-type A. hydrophila strain.

Abstract
AIMS This study was undertaken to cluster and identify a large collection of Aeromonas strains. METHODS AND RESULTS Numerical taxonomy was used to analyse phenotypic data obtained on 54 new isolates taken from water, fish, snails, sputum and 99 type and reference strains. Each strain was tested for 121 characters but only the data for 71 were analysed using the 'SSM' and 'SJ' coefficients, and the UPGMA clustering algorithm. At SJ values of > or = 81.6% the strains clustered into 22 phenons which were identified as Aer. jandaei, Aer. hydrophila, Aer. encheleia, Aer. veronii biogroup veronii, Aer. trota, Aer. caviae, Aer. eucrenophila, Aer. ichthiosmia, Aer. sobria, Aer. allosaccharophila, Aer. media, Aer. schubertii and Aer. salmonicida. The species Aer. veronii biogroup sobria was represented by several clusters which formed two phenotypic cores, the first related to reference strain CECT 4246 and the second related to CECT 4835. A good correlation was generally observed among this phenotypic clustering and previous genomic and phylogenetic data. In addition, three new phenotypic groups were found, which may represent new Aeromonas species. CONCLUSIONS The phenetic approach was found to be a necessary tool to delimitate and identify the Aeromonas species. SIGNIFICANCE AND IMPACT OF THE STUDY Valuable traits for identifying Aeromonas as well as the possible existence of new Aeromonas species or biotypes are indicated.

Abstract
BACKGROUND Described in 1916 by Theodore Leber, this rare syndrome characterized by low visual acuity, papillary edema, and a macular star (dry exsudates) occurs classically in the 30 to 40 year age range but also as frequently in children. The visual prognosis is excellent. An infectious cause is found in almost all cases. Case report A 34-year-old man consulted for declining visual acuity of the right eye which began suddenly without pain and was preceded by a flu-like syndrome lasting two weeks. Visual acuity on the right side was 2/10 P6, there was optic disk edema associated with dry macular exsudate (macular star) and a paleness of the posterior pole progressing to the periphery and readily visualized on the angiography, and a central scotome, but no dyschromatopsy. The left eye was strictly normal. Laboratory tests showed an erythrocyte sedimentation rate at 45, C reactive protein at 61, normal red cell count and minimal transaminase elevation. Spinal tap showed: 3 elements/mm(3), protein 0.28g/l, 18% gammaglobulins. Serology tests were negative. Brain imaging was normal. RESULTS Corticosteroid flashes for three days were initiated and the patient was seen again two weeks later with clear clinical improvement. Visual acuity was 6/10 P2 with considerable resorption of the edema. DISCUSSION This case is a typical illustration of acute Leber's neuroretinititis, probably caused by viral infection. The cerebrospinal fluid tests and brain imaging ruled out multiple sclerosis, and serology tests for syphilis, tuberculosis, Lyme disease and possible parasite infection were negative. CONCLUSION Acute lever's neuroretinitis is an uncommon condition which must be distinguished from inflammatory optic neuropathy, particularly in multiple sclerosis which has a very different prognosis and clinical course.

Abstract
BACKGROUND the parasite Anisakis simplex is a helminth included in the nematode class. When man eats raw or rare fish and cephalopods infested by Anisakis larvae, he can acquire the parasitic disease (anisakidosis). The parasite can also originate manifestations of immediate IgE mediated hypersensitivity in patients with sensitisation to it. METHODS AND RESULTS we present the case of a 14 year old boy diagnosed of eosinophilic gastritis after endoscopic examination and biopsy associated to recurrent abdominal pain. After allergologic study, a type I hypersensitivity mechanism against Anisakis simplex is confirmed by means of prick test, antigen specific IgE determination and antigen specific histamine release test. Sensitisation against fish proteins is ruled out as well as parasitic infestation. CONCLUSIONS in this case report we demonstrate a type I hypersensitivity mechanism against Anisakis simplex in a patient diagnosed of eosinophilic gastritis. This can be suspected in cases of gastritis or non filiated enteritis with a torpid evolution following the conventional treatment and especially if the onset of the symptoms is related with the intake of fish. The therapeutic success was reached when fish and shellfish were taken out of the diet. After two years without seafood ingestion our patient is asymptomatic and the allergologic study has been normalised.

Abstract
An enzyme-linked immunosorbent assay has been developed for the detection of Aeromonas hydrophila serogroup O:19 isolated from epizootics in eels. The enzyme-linked immunosorbent assay specificity was confirmed after testing A. hydrophila O:19 and non-O:19 strains from different origins, as well as other Aeromonas species and other fish pathogens such as Vibrio vulnificus biotype 2, V. furnisii, V. damsela, Yersinia ruckerii and Edwardsiella tarda. The detection limits for A. hydrophila O:19 cells were around 10(4)-10(5) cells/well. Artificially infected eels were analyzed and the immunodetection was confirmed by cultural methods. With this methodology A. hydrophila O:19 was successfully detected in infected eels and water samples. We described two subgroups within the serogroup O:19 (Guinée and Jansen system), one of them presents a 50 kDa outer membrane protein as a strong thermostable antigen which is not present in the other group.

Abstract
Four strains isolated from European eels in Valencia, Spain, were found to constitute a DNA relatedness group which is 0 to 50% related to the 13 species and DNA group 11 of the genus Aeromonas. Phenotypically, these strains have all of the properties that define the genus Aeromonas. However, they differ from the previously described Aeromonas species by three or more properties. The strains are positive for motility, growth at 37 degrees C, indole production, and arginine dihydrolase activity. They exhibit negative reactions in tests for growth at 42 degrees C and in thiosulfate-citrate-bile salts-sucrose medium (Oxoid), Simmons citrate tests, and tests for lysine and ornithine decarboxylase activities. They produce acid from salicin but not from L-arabinose, D-cellobiose, or lactose. All four strains hydrolyze esculin and arbutin but not elastin. They use L-serine as a sole carbon and energy source but cannot utilize L-arabinose, L-arginine, D-gluconate, or L-glutamine. The strains are resistant to ampicillin. The guanine-plus-cytosine content of the DNA is 59.4 to 60.8 mol%. The name Aeromonas encheleia sp. nov. is proposed for these strains; strain S181 (= CECT 4342) is the type strain. This new species is generally not pathogenic for eels or mice.

Abstract
The genomic relatedness among three Aeromonas allosaccharophila strains, including the type strain, and other Aeromonas type and reference strains that were assigned to DNA hybridization groups was estimated by DNA-DNA hybridization (competition procedure using a membrane method). All A. allosaccharophila strains were highly related (70 to 100%) to strains 289T (= CECT 4199T) and ATCC 35942. Type strains of other validated Aeromonas species, reference strains of DNA groups 8 and 11, and the Aeromonas sp. strain ATCC 43946 (enteric group 501) were 0 to 41% related to A. allosaccharophila 289T and ATCC 35942. The G+Cs content of A. allosaccharophila strains were in the range 55.9 to 57.3 mol%. The G+C content of the type strain of this species was 56.9 mol%, a value somewhat lower than that reported in the original description.

Abstract
Vibrio vulnificus biotype 2 is classically considered an obligate eel pathogen. However, it has recently been associated with one human septicemic case. In this paper, the opportunistic behavior of this pathogen is discussed. The bacterium can survive alone in brackish water or attached to eel surfaces for at least 14 days. It is able to spread through water and infect healthy eels by using skin as a portal of entry. These results suggest that water and infected eels may act as reservoirs of infection. A capsule seems to be essential for waterborne infectivity, which would explain why cells recovered from naturally diseased eels give rise to pure cultures of opaque colonies. The spread of the disease is dependent on temperature and water salinity, thus suggesting a method to reduce the risk of epizootics and that of infection for humans.

Abstract
The relationship between virulence, O-serogroup, and some cell-surface features (self-pelleting [SP] and precipitation after boiling [PAB], profile of lipopolysaccharides [LPSs] and outer membrane proteins [OMPs]) was investigated in strains of the pathogenic species Aeromonas hydrophila and A. jandaei isolated from eels. Virulent strains of A. hydrophila reacted mostly with O:19 antiserum, and those of A. jandaei reacted with O:4, O:11, O:15 and O:29 antisera (Guinée and Jansen system). Regarding the PAB and LPS profiles two groups could be distinguished; (i) five PAB+ strains of serotype O:19 that possessed a homogeneous O polysaccharide side chain and (ii) thirteen PAB- strains antigenically diverse that either exhibited a heterogeneous side chain or were side chain deficient. A major 50 kDa protein was only found in the PAB+ strains, whereas major OMPs detected in PAB- strains ranged from 33 to 45 kDa irrespective of the species. Epizootic eel isolates of A. hydrophila belong to serotype O:19 and share cell-surface features with the Aeromonas highly virulent for other hosts. In contrast, epizootic A. jandaei isolates were antigenically diverse. These findings reinforce the importance of an O-serotype as an epidemiological marker in motile Aeromonas strains pathogenic for eels.

Abstract
The incidence of diaphragmatic hernia in he newborn is 1:2,500 to 5,000 births. An extensive American programme of foetal surgery for in utero repair of this defect has shown that the pulmonary hypoplasia was due to compression of lung tissue by the herniated organs. This process could be interrupted be repairing the diaphragmatic defect early enough in utero (before the 28th week). The results of five years of experimental surgery for in utero correction of diaphragmatic hernia are presented here. The experimental model used was the Macaca fascicularis monkey, the pregnant female of which having several gestational and endocrine characteristics similar to those of the pregnant woman. Three different experimental programmes were carried out successively. A first series including five animals was used to experiment both surgical and anaesthetic techniques; three foetuses died in utero. The second series (10 animals) was designed to find a suitable protocol for tocolysis. One female died after surgery, and seven other foetuses also died. The third group (13 animals) was the main study group. The diaphragmatic hernia was first created surgically, and then repaired. No foetus died from the surgery. One female died before giving birth, and one offspring died shortly after birth as its mother had no milk. After the encouraging results obtained with this last series of animals, the procedure was applied to human cases, with the Hospital Ethical Committee's approval. In the first case, the foetus died postoperatively as a result of the rupture of the diaphragmatic prosthesis.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A new technique of sedation for children is described, in which midazolam (0.2 mg.kg-1) was administered topically by the nasal route, followed by ketamine (9.0 mg.kg-1) administered rectally in 32 patients breathing air spontaneously. Sedation was good in 23, seven required further ketamine (1.0 mg.kg-1 i.v.), and in two, halothane was introduced. There was no evidence of severe respiratory depression except during oesophagoscopy. Cardiovascular stability was excellent. Of 21 patients over 5 years old, 19 developed complete and two partial anterograde amnesia for the administration of ketamine and surgery. The major complications were nausea and vomiting (five patients) and salivation (eight patients). The mean recovery time was 40 min (s.d. 33 min). It provided a relatively safe, adaptable, non-invasive method of inducing sedation in children.

Abstract
Forty-eight consecutive patients (37 men, 11 women, mean age 49 +/- 8 years) were followed up regularly for a mean period of 7 years. All presented with spontaneous angina, documented coronary spasm and no stenosis greater than 50 p. 100 at coronary arteriography. The first attack of pain had taken place 3 days to 9 years previously; exertion angina was also present in 47 p. 100 of the cases and severe arrhythmia in 17 p. 100. Treatment was based on calcium antagonists in doses and combinations that varied with the course of the disease. The follow-up period lasted from 16 to 122 months (mean 85 +/- 24 months). 3 patients are now known to be alive but were lost sight of after 12 to 21 months. Major cardiac complications were 1 death (2 p. 100) and 3 cases of myocardial infarction (6.6 p. 100). None of the patients died suddenly. 70 p. 100 of the remaining 41 patients became asymptomatic; angina persisted in 15 p. 100 and 14 p. 100 had episodes of severe angina but with remissions of at least one year. No predictive factor of functional deterioration or major cardiac complications could be elicited. The long-term prognosis of vasospastic angina in patients with little or no coronary stenosis is favourable, but there is a very small risk of myocardial infarction or death.

Abstract
The cortisol response to surgery was studied in two groups of children one to eight years old during the first 24 hours after lower abdominal or peripheral surgery. The children were randomly allocated to a control (C) group (n = 6) or an epidural (E) group (n = 7). In Group C, surgery was performed under general anaesthesia and postoperative pain relief was achieved by using non-narcotic analgesics only. In Group E, lumbar epidural anaesthesia was combined with light general anaesthesia and postoperative pain relief was achieved by intermittent doses of bupivacaine administered through an epidural catheter. Cortisol levels were assessed before surgery (C), at the end of surgery (H0), at the 3rd, 6th, 12th and 24th postoperative hours (H3, H6, H12, H24). In Group C, cortisol levels increased significantly at H0, H3 and H6, whereas in Group E, a significant decrease was observed at H0 and a significant increase at H12. Mean cortisol values at H0 and H24 were significantly lower in Group E, when compared with those measured in Group C. In Group E, all postoperative cortisol values remained within the normal range, despite the low level of sensory blockade achieved. This suggests that minimal doses of epidural bupivacaine are effective in decreasing the endocrine stress response to surgery in children. This could be of clinical relevance in high-risk children with poor nutritional status. In Group C, the cortisol response remained altered for a longer period of time.

Abstract
This study reports the experience of a department of paediatric anaesthesia with 234 continuous extradural anaesthetics performed in 229 children over a 15-month period. Fifty-nine of the children were aged 0-2 yr, 71 were aged 2-8 yr and 104 were older than 8 yr. The surgical procedures lasted more than 60 min (mean 150 +/- 10.6 min); all were carried out under light general anaesthesia. Technical procedure and difficulties are reported. The only local anaesthetic agent used was bupivacaine with or without adrenaline. Mean initial dosage was 0.75 ml kg-1 for children weighing less than 20 kg and 1 ml/10 cm of height for children taller than 100 cm. Using 0.25% bupivacaine mean times until a further injection were 92.0 +/- 2.0 min for bupivacaine with adrenaline and 71.0 +/- 2.5 min for bupivacaine without adrenaline (P less than 0.001). A much longer duration of analgesia was found for younger children using the solution with adrenaline. A haemodynamic study was performed in 74 unpremedicated children (ASA I; aged 0-2 yr (n = 15), 2-8 yr (n = 26) and older than 8 yr (n = 35). Before induction of anaesthesia, heart rate (HR) was significantly increased in the youngest children, but no significant change was found for systolic arterial pressure (SAP). After extradural anaesthesia with 0.25% bupivacaine with adrenaline 1:200000, minimal changes in HR or SAP occurred in children younger than 8 yr; in those older than 8 yr a significant decrease in both HR and SAP was observed. Changes in SAP were at their maximum 25 min after the extradural block and changes in HR were not statistically significant before the 25th min following injection of local anaesthetic. The catheter remained in place in 155 children for postoperative analgesia, mainly for the first 48 h.

Abstract
The benefits of epidural anaesthesia combined with general anaesthesia were studied in young children scheduled for major abdominal surgical procedure (pull-through for Hirschsprung's disease). Two groups of nine children were studied receiving, respectively, general anaesthesia or general anaesthesia plus epidural anaesthesia. In the group receiving both general and regional anaesthesia, a polyurethane 24 G catheter was inserted via a Tuohy needle 19 G into the lumbar epidural space after induction of anaesthesia and intubation and bupivacaine, 0.25%, was injected epidurally (mean initial volume 0.71 +/- 0.04 ml kg-1). No opiates were needed during operation on the children in this group. After epidural anaesthesia, heart rate decreased significantly but systolic blood pressure remained unchanged. During surgery mean values of both heart rate and systolic blood pressure were significantly lower in the regional analgesia group compared to the general anaesthesia group. The need for blood replacement was also significantly lower, whereas pre- and post-operative haematocrit values were not significantly different. Administration of fluid and electrolytes during operation was also similar in both groups. A combination of epidural and general anaesthesia avoids the use of opiates during surgery, provides excellent per- and post-operative analgesia, allows a rapid and safe recovery, and facilitates the nursing of young children.

Abstract
Isoprinosine was shown to alter certain T cell functions. In vitro, it has previously been shown to induce suppressor cell activity in both mouse and human lymphocytes. Our in vitro results suggest that Isoprinosine acts on immune balance by increasing the number of non-suppressor T cells and, at least partially blocks Con A induced suppressor activity. In vitro NK activity remained unaltered.

Abstract
The immune status of the tumor-bearing patient remains poorly defined. In various solid-tumor-bearing patients, we demonstrated the absence of ADCC modifications in the patient in relapse or in evolution. These same patients presented a significant increase in immune complexes when compared with patients in remission. Furthermore, we noted a decreased NK activity, a decreased number of ARFC, corresponding to a helper T cell subpopulation, and a corollary increase in T-dependent suppressor activity. These results, on the whole, suggest an immune imbalance and that the helper cell-suppressor cell ratio should be investigated in greater depth within the context of the immune response in the cancer patient.
