Survey of aspergillosis in non-neutropenic patients in Swiss teaching hospitals.

Clin Microbiol Infect 2011; 17: 1366-1371 ABSTRACT: Invasive aspergillosis (IA) is a live-threatening opportunistic infection that is best described in haematological patients with prolonged neutropenia or graft-versus-host disease. Data on IA in non-neutropenic patients are limited. The aim of this study was to establish the incidence, disease manifestations and outcome of IA in non-neutropenic patients diagnosed in five Swiss university hospitals during a 2-year period. Case identification was based on a comprehensive screening of hospital records. All cases of proven and probable IA were retrospectively analysed. Sixty-seven patients were analysed (median age 60 years; 76% male). Sixty-three per cent of cases were invasive pulmonary aspergillosis (IPA), and 17% of these were disseminated aspergillosis. The incidence of IPA was 1.2/10 000 admissions. Six of ten cases of extrapulmonary IA affected the brain. There were six cases of invasive rhinosinusitis, six cases of chronic pulmonary aspergillosis, and cases three of subacute pulmonary aspergillosis. The most frequent underlying condition of IA was corticosteroid treatment (57%), followed by chronic lung disease (48%), and intensive-care unit stays (43%). In 38% of patients with IPA, the diagnosis was established at autopsy. Old age was the only risk factor for post-mortem diagnosis, whereas previous solid organ transplantation and chronic lung disease were associated with lower odds of post-mortem diagnosis. The mortality rate was 57%.

Right Hepatectomy in Patients over 70 Years of Age: An Analysis of Liver Function and Outcome.

BACKGROUND: As a consequence of the increase in life expectancy, hepatobiliary surgeons have to deal with an emerging aged population. We aimed to analyze the liver function and outcome after right hepatectomy (RH) in patients over 70 years of age. METHODS: From January 2006 to December 2009, we prospectively collected data of 207 consecutive elective hepatectomies. In patients who had RH, cardiac risk was assessed by a dedicated preoperative workup. Liver failure (LF) was defined by the "fifty-fifty" criteria at postoperative day 5 (POD) and morbidity by the Clavien-Dindo classification. Liver function tests (LFTs) and short-term outcome were retrospectively analyzed in patients over (elderly group, EG) and younger (young group, YG) than 70 years of age. RESULTS: Eighty-seven consecutive RH were performed during the study period. Indication for surgery included 90 % malignancy in 47 % of patients requiring preoperative chemotherapy. ASA grade > 2 (44 vs. 16 %, p = 0.027), ischemic heart disease (17 vs. 5 %, p = 0.076), and preoperative cardiac failure (26 vs. 2 %, p < 0.001) were more frequent in the EG (n = 23) than in the YG (n = 64). Both groups were similar regarding rates of normal liver parenchyma, chemotherapy and intraoperative parameters. The overall morbidity rates were comparable, but the serious complication (grades III-V) rate was relatively higher in the EG (39 vs. 25 %, p = 0.199), particularly in patients with diabetes mellitus (100 vs. 29 %, p = 0.04) and those who had additional nonhepatic surgery (67 vs. 35 %, p = 0.110) and transfusions (44 vs. 30 %, p = 0.523). The 90-day mortality rate was similar (9 % in the EG vs. 3 % in the YG, p = 0.28) and was related to heart failure in the EG. LFTs showed a similar trend from POD 1 to 8, and patients ≥70 years of age had no liver failure. CONCLUSIONS: Age ≥70 years alone is not a contraindication to RH. However, major morbidity is particularly higher in the elderly with diabetes. This high-risk group should be closely monitored in the postoperative course. Liver function is not altered in the elderly patient after RH.

Identifying and Implementing Effective Training for Hispanic Craft Workers, American Supervisors, and DOT Inspectors: Phase III of the Hispanic Workforce Research Project, May 2006

The number of Hispanic workers in the U.S. construction industry has been steadily increasing, and language and cultural barriers have sometimes arisen on the jobsite. Due in part to these barriers, the number of fatalities among Hispanics at construction sites in 2001 jumped 24%, while construction fatalities overall dropped 3%. This study, which constitutes Phase III of the Hispanic Workforce Research Project, addresses these language and cultural barriers by investigating the most effective way to deliver training material developed in Phases I and II to Hispanic workers, American supervisors, and department of transportation (DOT) inspectors. The research methodology consisted of assessing the needs and interests of potential and current course participants in terms of exploring innovative ways to deliver the training. The training courses were then adapted and delivered to fit the specific needs of each audience. During Phase III of this project, the research team delivered the courses described in the Phase I and II reports to eight highway construction companies and two DOT groups. The courses developed in Phases I and II consist of four construction-focused language training courses that can be part of an effective training program to facilitate integration among U.S. and Hispanic workers, increase productivity and motivation at the jobsite, and decrease the existing high mortality rate for Hispanic workers. Moreover, the research team developed a course for the construction season called Toolbox Integration Course for Hispanic workers and American supervisors (TICHA), which consists of nine 45-minute modules delivered to one construction company over 11 weeks in the summer of 2005.

What do women do? World population growth and fertility patterns, 1960-2000

In this paper we attempt to describe the general picture reasons behind the world population explosion during the 20th century. In general we comment that if, according to some, at the end of the 20th century there were too many people, this was has a consequence of scientific innovation, circulation of information, and economic growth, leading to a dramatic improvement in life expectancies. Nevertheless, a crucial variable shaping differences in demographic growth is fertility. In this paper we identify as important exogenous variables affecting fertility female education levels, infant mortality, and racial identity and diversity. It is estimated that three additional years of schooling for mothers leads on average (at the world level ) to one child less per couple. Even if we can identify a worldwide trend towards convergence in demographic trends, the African case needs to be given more attention, not only because of its different demographic patterns, but also because this is the continent where the worldwide movement towards a higher quality of life has not yet been achieved for an important share of the world's population.

Procalcitonin for reduced antibiotic exposure in ventilator-associated pneumonia: a randomised study.

In patients with ventilator-associated pneumonia (VAP), guidelines recommend antibiotic therapy adjustment according to microbiology results after 72 h. Circulating procalcitonin levels may provide evidence that facilitates the reduction of antibiotic therapy. In a multicentre, randomised, controlled trial, 101 patients with VAP were assigned to an antibiotic discontinuation strategy according to guidelines (control group) or to serum procalcitonin concentrations (procalcitonin group) with an antibiotic regimen selected by the treating physician. The primary end-point was antibiotic-free days alive assessed 28 days after VAP onset and analysed on an intent-to-treat basis. Procalcitonin determination significantly increased the number of antibiotic free-days alive 28 days after VAP onset (13 (2-21) days versus 9.5 (1.5-17) days). This translated into a reduction in the overall duration of antibiotic therapy of 27% in the procalcitonin group (p = 0.038). After adjustment for age, microbiology and centre effect, the rate of antibiotic discontinuation on day 28 remained higher in the procalcitonin group compared with patients treated according to guidelines (hazard rate 1.6, 95% CI 1.02-2.71). The number of mechanical ventilation-free days alive, intensive care unit-free days alive, length of hospital stay and mortality rate on day 28 for the two groups were similar. Serum procalcitonin reduces antibiotic therapy exposure in patients with ventilator associated pneumonia.

Evolução Demográfica da Ilha de São Vicente do Descobrimento a 1950

Este trabalho propõe-se analisar a evolução demográfica da ilha de São Vicente, desde o seu descobrimento até 1950. A análise é complementada pelo estudo da natalidade e mortalidade desta ilha que, à semelhança do resto do arquipélago, foi marcada histórica e demograficamente por cíclicas crises de mortalidade e uma elevada natalidade. As particularidades da ilha prendem-se com o seu povoamento tardio e com a sua ligação ao Porto Grande que lhe deu uma dinâmica diferente do resto do país. A pesquisa foi desenvolvida nos arquivos da Conservatória do Registo Civil de São Vicente e da Câmara Municipal de São Vicente. The present work aims at analysing the demographic evolution on the island of S. Vicente since its discovery till 1950, being the analysis complemented by a study on birth and mortality rates on this island. Similarly to the other islands, these rates were marked, both historically and demographically, by recurrent mortality crises, as well as by high birth-rate. The island particularities not only result from its late settlement, but also from its close relationship with the “Porto Grande” harbour, which conferred it a different dynamic, if compared to other parts of this country. This research was based on the files recorded at the Registry Office and the Town-Hall, both in S. Vicente.

Acquired form of angioedema of the head and neck related to a deficiency in c1-inhibitor: a case report with a review of the literature.

Angioedema related to a deficiency in the C1-inhibitor protein is characterized by its lack of response to therapies including antihistamine, steroids, and epinephrine. In the case of laryngeal edema, mortality rate is approximately 30 percent. The first case of the acquired form of angioedema related to a deficiency in C1-inhibitor was published in 1972. In our paper, we present a case of an acquired form of angioedema of the oropharyngeal region secondary to the simultaneous occurrence of two causative factors: neutralization of C1-inhibitor by an autoantibody and the use of an angiotensin convertin enzyme inhibitor.

Arginase as a marker of disease severity in human leishmaniasis

The leishmaniases are a group of diseases transmitted by the bite of Leishmania infected female phlebotomine sand flies. The diseases occur in different forms: localized, diffuse and muco-cutaneous leishmaniasis, and visceral leishmaniasis (VL). Inside macrophages, the main host cells of the obligate intracellular Leishmania parasites, nitric oxide synthase and arginase can regulate parasite killing or growth. In experimental leishmaniasis, we previously reported that non-healing disease is associated with higher arginase activity at site of pathology, correlating with local suppression of T cell function. To test whether these data translate to human leishmaniasis, the following study was initiated: I first tested the hypothesis that local suppression of T cell responses observed in persistent CL is associated with arginase induced L-arginine depletion. The results showed that arginase activity is increased at site of pathology compared to peripheral blood mononuclear cells (PBMCs) of LCL patients and intact skin of healthy controls. The phenotype of arginase expressing cells was identified in both compartments as CD15+ CD14|0W low-density granulocytes (LDGs). Finally, high arginase activity at site of pathology observed in cutaneous lesions of patients coincides with downregulation of CD3Ç, CD4 and CD8 molecules in CD4+ and CD8+ T cells at site of pathology. We concluded that increased arginase levels in lesions of LCL patients might contribute to CL pathogenesis by impairing T cell effector function at site of pathology. Next, it was tested whether arginase, an enzyme associated with immunosuppression, is higher in patients with VL and contributes to impaired T cell function through depletion of L- arginine. The results showed that higher level of arginase activity in the PBMC coincides with active phase of VL. Cells expressing arginase in PBMCs were also found to be LDGs. Importantly, increased arginase activity and frequency of degranulated neutrophils coincided with lower plasma L-arginine levels. Furthermore, downregulation of CD3Ç, in T cells correlated with low plasma arginine levels. VL/HIV co-infection is a frequently reported leishmaniasis complication in Ethiopia associated with poor prognosis, with up to 40% mortality rate and high relapse rate. Arginase activity was significantly increased in PBMCs and plasma of VL patients co-infected with HIV than in those having VL alone. Similarly, cells expressing arginase in PBMCs were found to be LDGs. In summary, the results presented here show that increased arginase activity is a marker of disease severity in human leishmaniasis with and without HIV; further, these results suggest that arginase mediated L-arginine depletion may inhibit T cell function and contribute to impaired control of infection. - Les leishmanioses sont un groupe de maladies transmises par la piqûre de mouches des sables femelles, appelées phlébotomes, ayant été infectées par Leishmania. Les maladies se manifestent sous différentes formes: la leishmaniose cutanée localisée, la leishmaniose diffuse et mucocutanée et la leishmaniose viscérale (LV). A l'intérieur des macrophages, les principales cellules hôtes des parasites, l'oxyde nitrique synthase et l'arginase, peuvent contrôler, soit la mort du parasite, soit sa croissance. Pour la leishmaniose expérimentale, nous avons déjà rapporté que le développement de lesions qui ne guérissent pas est associé à une activité plus grande d'arginase au site d'infection, en corrélation avec la suppression locale de la fonction des cellules T. Pour vérifier si ces données pouvaient s'appliquer à la leishmaniose humaine, j'ai d'abord vérifié l'hypothèse selon laquelle la suppression locale des réponses des cellules T observée dans la CL persistante, est associée à la la diminution de L- arginine induite par l'arginase. Les résultats ont montré que l'activité arginase est augmentée au site d'infection, par rapport aux cellules mononucléées du sang périphérique (CMSP) de patients LCL et à la peau intacte des contrôles sains. Le phénotype de cellules exprimant l'arginase a été identifié dans les deux compartiments comme des granulocytes CD15+ et CD 14" de basse densité (LDG). Enfin, l'activité arginase élevée au site de la pathologie, observée dans les lésions cutanées de patients, coïncide avec la reduction dde l'expression des molécules CD3Ç, CD4 et CD8 dans les cellules T CD4+ et CD8+ au site de pathologie . Nous avons conclu que l'augmentation des niveaux d'arginase dans les lésions de patients LCL pourrait contribuer à la pathogenèse de la CL, en altérant la fonction effectrice des celllules T au site de la pathologie. Ensuite, nous avons vérifié si l'arginase, une enzyme associée à l'immunosuppression, était plus élevée chez les patients atteints de VL et si elle contribuait à la mauvaise fonction des cellules T par la depletion en L-arginine. Les résultats ont montré qu'un niveau plus élevé de l'activité arginase dans les PBMC correspond à la phase active de la VL. Les cellules exprimant l'arginase dans les CMSP se sont révélées à être de type LDG . Il est important de souligner que l'augmentation de l'activité arginase et la fréquence des neutrophiles dégranulés a coïncidé avec des niveaux inférieurs de L-arginine plasmatique. En outre, la suppression de CD3Ç dans les cellules T correlle avec de faibles niveaux d'arginine plasmatique . Il a été fréquement rapporté que la co-infection VL/VIH est une complication de la leishmaniose en Ethiopie, associée à un mauvais prognostic, un taux de mortalité pouvant atteindre 40% et un pourcentage élevé de rechutes. L'activité de l'arginase a beaucoup plus augmentée dans les CMSP et le plasma de patients atteints de VL et co-infectés par le VIH, que chez ceux seulement attaints de VL. De même, les cellules exprimant l'arginase dans les CMSP sont aussi des LDG. En résumé, les résultats présentés ici montrent que l'augmentation de l'activité de l'arginase est un marqueur de gravité de la la leishmaniose humaine, avec ou sans VIH ; en outre, ces résultats suggèrent que la déplétion de L-arginine par l'arginase pourrait inhiber la fonction des cellules T et contribuer à un contrôle réduit de l'infection. - Les Leishmanioses sont des maladies parasitaires transmises par la piqûre d'une mouche des sables femelle (phlébotome) infectée par Leishmania. La maladie se manifeste sous différentes formes cliniques : la leishmaniose viscérale, une maladie progressive mortelle en l'absence de traitement, la leishmaniose muco-cutanée (MCL), la leishmaniose cutanée diffuse (LCD ) maladie mutilante, qui peut être de longue durée et la leishmaniose cutanée localisée maladie dont on guérit mais laissant une cicatrice inesthétique à vie. La maladie est largement répandue, elle affecte les populations les plus pauvres dans 98 pays et 350 millions de personnes à risque. Globalement on estime à 500.000 les nouveaux cas de la forme viscérale et 1-1.5 million ceux de la leishmaniose cutanée. La leishmaniose est fortement endémique en Ethiopie et se manifeste dans les formes viscérale et cutanée. Le parasite Leishmania infecte et se multiplie dans les cellules du système immunitaire, principalement les macrophages. Les macrophages sont capables de tuer le parasite Leishmania s'ils reçoivent des instructions correctes de la part d'autres cellules du système immunitaire, les lymphocytes. Les macrophages expriment deux enzymes importants, appelés oxide nitrique synthase inductible (iNOS ) et l'arginase, qui sont respectivement associés à la promotion de la mort du parasite et la multiplication. L'enzyme iNOS présent dans les macrophages métabolise l'arginine afin de générer de l'oxyde d'azote (NO) , une molécule effectrice nécessaire pour tuer le parasite . Au contraire, lorsque les macrophages sont activés d'une certaine manière conduisant à l'augmention de la régulation de l'arginase, ils métabolisent l'arginine en polyamines qui favorisent la croissance du parasite. Au cours du développement de la leishmaniose, les lymphocytes ne parviennent pas à transmettre aux macrophages les signaux nécessaires pour tuer le parasite. Les mécanismes cellulaires qui sont la cause de ce défaut, ne sont pas bien compris. En utilisant des modèles animaux, nous avons montré la régulation à la hausse de l'arginase au site de la pathologie, qui s'est traduit par l'altération de la fonction effectrice des lymphoctes. Nous avons initié des études de leishmaniose humaine en Ethiopie afin d'identifier le rôle de l'arginase dans la sévérité de la maladie. Nos résultats montrent, que l'arginase est fortement augmentée dans la lésion des patients CL, et dans le sang des patients VL et ceux co-infectés par VL / VIH. Le niveau d' arginase régulée à la hausse coincide avec l'expression inférieure d'une molécule de signalisation dans les lymphocytes, qui est essentielle à leur bon fonctionnement. En VL actif, l'augmentation d'arginase se traduit par la diminution de l'arginine qui est indispensable à la synthèse de NO et au bon fonctionnement des lymphocytes. Ainsi, l'incapacité des lymphocytes à envoyer des signaux adéquats aux macrophages pourrait être due à la suppression de l'arginine.

Map of homicides by firearms: profile of the victims and the assaults

AbstractOBJECTIVEDescribing the profile of victims and assaults by gunshot, where the outcome was death.METHODAn ecological study conducted in the city of Maceió/AL, in 2012. Data were collected from the death statements. The variables studied were: the death circumstances, gender, age, marital status, place, date, time, month and proportion according to the occurring neighborhood.RESULTSThe homicide mortality rate was 65.2 per 100,000 inhabitants, with 130.6 per 100,000 men and 7.8 per 100,000 women. Of the total number of homicides, 93.6% of the victims were men. The age group between 15 and 29 years of age was the most affected, with 68.8%. In 97.6% of cases the death occurred at the site of aggression, 74.1% in the streets. In relation to the date, 54.2% of cases occurred between Friday and Sunday. 59.7% of the homicides were concentrated in seven neighborhoods.CONCLUSIONThe map of violence presented shows heterogeneous areas for the occurrence of assaults with firearms, characterizing the existing urban inequality in violence distribution.

Comparative biology of Cycloneda sanguinea (Linnaeus, 1763) and Hippodamia convergens Guérin-Méneville, 1842 (Coleoptera, Coccinellidae) focusing on the control of Cinara spp. (Hemiptera, Aphididae)

The giant conifer aphids Cinara pinivora (Wilson, 1919) and Cinara atlantica (Wilson, 1919) (Hemiptera, Aphididae) have been observed attacking Pinus spp. in Southern and Southeastern Brazil. The coccinellids, on the other hand, were found feeding on these aphids in the field, which can be regarded as potential biological control agents. The biological cycle and mortality rate of larvae of Cycloneda sanguinea (Linnaeus, 1763) and Hippodamia convergens Guérin-Méneville, 1842 (Coleoptera, Coccinellidae) were evaluated using twenty larvae of each predator species fed with nymphs of Cinara. The vials with the insects were kept under 15 ºC, 20 ºC and 25 ºC, with 12h photophase and 70 ± 10% relative humidity. The consumption was evaluated every 24 hours and the nymphs replaced. For C. sanguinea, the egg incubation time was 10.5, 5.0 and 4.0 days; the average larval development period was 33.3, 15.8 and 8.6 days and the larval mortality rate 20%,0% and 15%, respectively at 15 ºC, 20 ºC and 25 ºC. For H. convergens, the larval development time was 41.9, 19.3 and 10.9 days at 15 ºC, 20 ºC and 25 ºC, respectively. The larval mortality rate was 35%, 15% and 0% under the three temperatures. Both species developed adequately when fed nymphs of Cinara, however, C. sanguinea performed better than H. convergens, even at 15 ºC, at which temperature the biological cycles of the coccinellids are prolonged, but the temperature is favorable for the development of Cinara populations in the field.

World population growth and fertility patterns, 1960-2000. A simple model explaining the evolution of world's fertility during the second half of the 20th Century

In this paper we attempt to describe the general reasons behind the world populationexplosion in the 20th century. The size of the population at the end of the century inquestion, deemed excessive by some, was a consequence of a dramatic improvementin life expectancies, attributable, in turn, to scientific innovation, the circulation ofinformation and economic growth. Nevertheless, fertility is a variable that plays acrucial role in differences in demographic growth. We identify infant mortality, femaleeducation levels and racial identity as important exogenous variables affecting fertility.It is estimated that in poor countries one additional year of primary schooling forwomen leads to 0.614 child less per couple on average (worldwide). While it may bepossible to identify a global tendency towards convergence in demographic trends,particular attention should be paid to the case of Africa, not only due to its differentdemographic patterns, but also because much of the continent's population has yet toexperience improvement in quality of life generally enjoyed across the rest of theplanet.

Les adénocarcinomes kystiques de la glande lacrymale [Cystic adenocarcinomas of the lacrymal gland]

Adenoid cystic carcinoma of the lacrimal gland. BACKGROUND: Adenoid cystic carcinoma is the most frequent epithelial tumour of the lacrimal gland. It represents 1.6 % of the orbital tumours. The aim of this study is to present a series of such patients who were followed up in our clinic and to discuss their clinical management in order to achieve a better life prognosis. MATERIALS AND METHODS: The cases we followed up in our department were presented, the treatment modalities were discussed, and conclusions were drawn. RESULTS: Six patients with this pathology were examined, 3 men and 3 women, aged 31 to 69 years. A large excision was performed in 5 patients (exenteration alone or extended exenteration with complementary radiotherapy) and in 1 patient with excision of the tumour followed by radiotherapy. One patient died due to carcinoma six years after the first surgery. The median follow-up period of our cases is 25 months. CONCLUSION: Adenoid cystic carcinoma of the lacrimal gland is a malignant tumour with a reserved prognosis. Various treatments were proposed to improve the mortality rate of the disease. At present radical surgery with or without complementary therapy seems to give the best chances of healing, at least with short or mid-term follow-up.

Prophylaxie de l'endocardite infectieuse : apport du modèle expérimental

Il est admis que l'endocardite infectieuse devrait faire l'objet d'une prophylaxie antibiotique du fait d'une morbidité et d'une mortalité non négligeables. Le choix de cette prophylaxie repose sur l'identification (i) des patients à risque, (ii) des interventions médico-chirurgicales pouvant provoquer une bactériémie, (iii) du régime prophylactique le plus efficace et (iv) du rapport entre le risque des effets secondaires des médicaments et celui de développer une endocardite infectieuse. Les patients à risque et les interventions médico-chirurgicales provoquant une bactériémie ont été identifiés par des études cliniques. En revanche, l'efficacité de la prophylaxie n'est fondée que sur les résultats de modèles animaux. L'expérimentation animale a contribué à une meilleure connaissance des mécanismes de pathogenèse de l'endocardite infectieuse. Elle a permis de comprendre le mode d'action des antibiotiques dans la prévention des endocardites infectieuses et de jeter les bases d'une antibioprophylaxie raisonnée et adaptée aux différents patients à risque. It is commonly agreed that infectious endocarditis should be handled by antibiotic prophylaxis whenever possible because of its significant morbidity and mortality rate. The choice of the type of prophylaxis depends on the identification (i) of the patients with risk factors (ii), of medico surgical procedures possibly causing bacteremia (iii), of the most efficient prophylactic program and (iv) of the balance between secondary effects of medication and the risk of developing infectious endocarditis. The patients with risk factors and the medico surgical procedures causing bacteremia have been clearly identified by clinical research, whereas efficiency of prophylaxis is only established on the results of animal models. Animal experimentation contributed to a better understanding of the mechanisms of pathogenesis of infectious endocarditis. It made it possible to understand the functioning of antibiotics in the topic of the prevention of infectious endocarditis and to settle the basis of a judicious antibiotic prophylaxis adapted to the various patients with risk factors.

Development of the immature stages of Culex (Culex) saltanensis Dyar (Diptera, Culicidae) under laboratory conditions

Development of the immature stages of Culex (Culex) saltanensis Dyar (Diptera, Culicidae) under laboratory conditions. Culex (Culex) saltanensis Dyar, 1928 is becoming frequent and abundant in natural and artificial breeding sites in urban and rural areas of Brazil. This study contributes to the knowledge of the biology of a Brazilian strain of C. saltanensis. The development of specimens reared individually or grouped was observed. The study was conducted at a constant temperature of 27 ± 2°C, 14L:10D photoperiod and 80 ± 5% relative humidity. The immature stages were observed every 6 hours until adult emergence, which occurred in 12.29 days among individually reared specimens and in 13.12 days among group-reared specimens. Egg rafts for the experiment were obtained from the laboratory and field. Eggs hatched at a rate of 97.48 ± 2.32%. More eggs per egg raft were obtained from the field than from the laboratory. Males from individually reared specimens emerged in 12.29 ± 1.11 days and females in 13.12 ± 1.58 days. The male-female ratio was 1:1. Larval survival rate was higher than 85% for larvae reared isolated and higher than 95% for group-reared larvae. The Culex saltanensis life cycle was completed within 12 to 14 days, where larval instars I and IV took the most time to develop and the pupae, the shortest.

Allergo-immunologie. 1. Nouveautés dans le traitement des crises aiguës d'angioedème héréditaire [Allergy-immunology. New therapies for acute attacks in hereditary angioedema].

Hereditary angioedema is a disease which develops as a result of a deficiency or dysfonction of C1-inhibitor, a key regulator of the complement, coagulation and contact cascades, resulting among others in excessive release of bradykinin. This disease mortality rate is high in absence of immediate and effective treatment, in particular in presence of acute attacks of the upper respiratory tract (laryngeal edema). Until now only administration of a purified C1-inhibitor extract was effective against these symptoms. This paper aims to synthesise essentials knowledge concerning news drugs, in particular icatibant, a selective bradykinin B2- receptor antagonist whose use should be widened to the treatment of angioedema with ACE-inhibitors intolerance.
