Abstract
Mycotoxins are widely occurring in foods and feeds and dietary exposure to them can induce various types of adverse health effects in humans and animals. Since its establishment in 2002, the European Food Safety Authority (EFSA) has assessed risks of dietary exposure to mycotoxins for public health and for the health of farm and companion animals on the request of the European Commission and has assessed safety and efficacy of feed additives for the reduction of contamination of feed by mycotoxins within the European Union authorisation process for feed additives. Over 40 scientific opinions on risks of mycotoxins for human and animal health and other reports on mycotoxins have been issued by the authority for the use of the European risk managers. Mycotoxins belong to one of the important areas of the EFSA work. Occurrence data on mycotoxins submitted to EFSA by the European national food safety bodies and research institutions have been collected in the EFSA databases and have informed its scientific opinions and reports on mycotoxins. Similarly, many EFSA-funded projects conducted by the European research organisations, not only to generate data on occurrence, but also data on toxicity of mycotoxins, have provided valuable information for the risk assessments of EFSA. Aflatoxin and deoxynivalenol are the mycotoxins, for which EFSA has delivered most of its scientific mycotoxin opinions. Very recently also modified forms of mycotoxins have been included in the EFSA risk assessments. In this review paper an overview of many different EFSA activities on mycotoxins is given. It also includes a brief description how EFSA develops its scientific opinions and works.

Abstract
The diagnosis of catheter-related bloodstream infections (CRBSIs) in febrile patients with indwelling central venous catheters (CVCs) needs improvement. To diagnose CRBSIs more efficiently, we have developed a novel culture approach using the catheter tips removed from febrile patients. CVCs and blood cultures from 1,070 patients with only CVC-related infections were obtained over a period of 3 years (January 2009 to December 2011). The CVCs were evaluated by a semi-quantitative catheter culture method according to Maki's method and by our novel method, which is based on the use of the HB&L UROQUATTRO™ system (Alifax, Padova, Italy). Using our new method, 571 (571/1,070) of the infections were confirmed as CRBSIs. The remaining 487 patients had infections that were associated with hematologic malignancies, neutropenia, prior exposure to antibiotics, and a decreased CVC removal rate. Twelve samples were identified as false-positives. The percentage of patients with CRBSIs confirmed using the HB&L UROQUATTRO™ system was 53.36 % versus 34.95 % (p-value 0.004) using Maki's method (374/1,070 CVC Maki-positive samples). Our results indicate that our new culture method allows for an improved CRBSI diagnosis rate. A significant number of tip cultures (18.41 %) tested positive for CRBSIs using our system but were negative when tested using Maki's method. Moreover, the use of the HB&L UROQUATTRO™ system allowed us to significantly reduce diagnosis time; a negative CRBSI diagnosis could be made within 6 h and a positive diagnosis could be made within 22-28 h.

Abstract
BACKGROUND Extracellular matrix degradation, mediated by the urokinase plasminogen activation (uPA) system, is a critical step in tumor invasion and metastasis. High tumor levels of uPA and its inhibitor PAI-1 have been correlated with poor cancer prognosis. We examined four single nucleotide polymorphisms (SNPs) with a potential effect on expression of genes in the uPA system for their role in colorectal cancer susceptibility and prognosis. PATIENTS AND METHODS We genotyped the SNPs in 308 Swedish incident colorectal cancer patients with up to 16 years of follow-up and in 585 age- and sex-matched controls. We evaluated the associations between genotypes and colorectal cancer and Dukes' stage. Survival probabilities were compared between different subgroups. RESULTS Patients with PAI-1 -675 5G/5G genotype had better survival than patients with 4G/4G or 4G/5G genotypes when they had Dukes' stage A or B tumors (P = 0.023 and P = 0.015, respectively). No statistically significant association was observed between the SNPs and the risk of colorectal cancer or Dukes' stage. CONCLUSIONS Our results suggest a role for the PAI-1 genotype in colorectal cancer prognosis, but further studies are needed to evaluate the impact of our finding in the clinic.

Abstract
Even with good surveillance programmes, hospital-acquired infections (HAIs) are not always recognized and this may lead to an outbreak. In order to reduce this risk, we propose a model for prompt detection of HAIs, based on the use of a real-time epidemiological information system called VIGI@ct (bioMèrieux, Las Balmas, France) and on the rapid confirmation or exclusion of the genetic relationship among pathogens using fluorescent amplified length fragment polymorphism (f-AFLP) microbial fingerprinting. We present the results of one year's experience with the system, which identified a total of 306 suspicious HAIs. Of these, 281 (92%) were 'confirmed' by clinical evidence, 16 (5%) were considered to be simple colonization and the latter nine (3%) were archived as 'not answered' because of the absence of the physician's cooperation. There were seven suspected outbreaks; of these, f-AFLP analysis confirmed the clonal relationship among the isolates in four cases: outbreak 1 (four isolates of Pseudomonas aeruginosa), outbreak 2 (three Escherichia coli isolates), outbreak 6 (two Candida parapsilosis isolates) and outbreak 7 (30 ESbetaL-producing Klebsiella pneumoniae subsp. pneumoniae). Based on our results, we conclude that the combination of VIGI@ct and f-AFLP is useful in the rapid assessment of an outbreak due to Gram-positive or Gram-negative bacteria and yeasts.

Abstract
We analysed the effects of number of siblings on the risk of solid tumours using the Swedish Family-Cancer Database, including population-based information on over 11 million individuals and more than 178 000 cancer patients diagnosed between 1958 and 2004. Incidence rate ratios (RRs), estimated by Poisson regression models, were adjusted for age, sex, birth cohort, area of residence and socioeconomic status. Having eight or more siblings vs none increased the risk of stomach cancer (RR=1.83, 95% confidence interval (CI), 1.44–2.34). Anal cancer diagnosed before age 40 showed the strongest association with the total siblings (RR=3.27, 95% CI, 2.04–5.26 for five or more siblings vs none). Endometrial (RR=0.76, 95% CI, 0.70–0.82), testicular (RR=0.71, 95% CI, 0.62–0.82), skin cancer (RR=0.82, 95% CI, 0.69–0.97) and melanoma (RR=0.72, 95% CI, 0.65–0.79) showed strong decreased risks for five or more siblings vs none. Prostate cancer risk for those with five or more older siblings vs none was 1.38 (95% CI, 1.23–1.55). Having five or more younger siblings was most strongly associated with stomach cancer (RR=1.59, 95% CI, 1.29–1.95) and melanoma (RR=0.68, 95% CI, 0.59–0.79). We conclude that sibship characteristics are strong correlates of cancer risk at several sites; plausible interpretations include socioeconomic status.

Abstract
BACKGROUND Cirrhosis is strongly related to liver cancer. Data on the possible association between cirrhosis and risk at other cancer sites are scanty. PATIENTS AND METHODS We analysed data from a network of case-control studies conducted in Italy between 1983 and 1997, including patients with cancers of the oral cavity and pharynx (520), oesophagus (405), stomach (731), colon (943), rectum (613), liver (425), gallbladder (63) and pancreas (395). The controls were 4297 patients admitted to hospitals for acute non-neoplastic conditions. RESULTS After strict allowance for alcohol drinking, tobacco smoking and history of hepatitis, the multivariate odds ratios for a history of cirrhosis were 4.7 [95% confidence interval (CI) 2.2-9.8] for neoplasms of the oral cavity and pharynx, 2.6 (95% CI 1.2-5.7) for the oesophagus, 1.0 (95% CI 0.4-2.5) for the stomach, 1.0 (95% CI 0.4-2.4) for the colon, 1.7 (95% CI 0.7-4.1) for the rectum, 20.5 (95% CI 12.3-34.2) for the liver, 2.1 (95% CI 0.3-16.8) for the gallbladder and 0.9 (95% CI 0.3-3.0) for the pancreas. CONCLUSIONS Our study confirms and further quantifies the increased risk of liver cancer in cirrhotic patients and is compatible with an increased risk of oral, pharyngeal and oesophageal cancers.

Abstract
BACKGROUND According to the "hygiene hypothesis" selected allergic diseases could be prevented by exposure to infectious agents during early childhood. METHODS This study was performed to assess the feasibility of a future meta-analysis on the "hygiene hypothesis" and atopic diseases. Differences concerning the potential association with a history of infectious events, in terms of magnitude and homogeneity of global risk estimates between the three major atopic diseases (i.e. atopic dermatitis, asthma and allergic rhinitis) were examined. We conducted a preliminary analysis on a sample of articles published on this topic and cited in a recent and authoritative review. RESULTS The ranges of relative risks estimates (between 0.6 and 0.8) were similar for atopic dermatitis, allergic rhinitis and asthma. Compared with asthma and allergic rhinitis, reported global risk estimates were more stable for atopic dermatitis (lowest heterogeneity). Our analysis suggests that three main categories of indirect markers of exposure to infection can be identified: 1) geographical gradient, 2) indices of potential contact with infectious agents (such as number of siblings) and 3) history of infectious events. CONCLUSIONS In this exploratory study, we chose articles cited in a single review and obtained a preliminary quantification of the association between infections and atopic diseases. The association with indirect markers of infection corresponded to 20% protection for atopic dermatitis, 30% for allergic rhinitis and 40% for asthma. In a subsequent meta-analysis, diseases should be considered separately and differences between types of exposures should be taken into account as one of the major end-points, with attention to time since exposure and disease onset.

Abstract
Jugular vein catheterization (JVC) is adopted for blood access in patients with acute renal failure, chronic renal failure and when patients demonstrate traditional vascular access (VA) failure. We believe that the best technique, first described by Serafini et al, to establish the position of a central venous catheter (CVC) is endocavitary electrocardiography (EC-ECG) and its use is recommended in all uremic patients requiring hemodialysis (HD). This technique uses the tip of the CVC as a reference point in standard electrocardiography. From 2001 to March 2004, we successfully applied this CVC technique in 33 patients requiring HD. The EC-ECG technique is a method that complies with the Food and Drug Administration guidelines regarding catheter tip location in uremic patients.

Abstract
The role of cigarette smoking on the risk of Hodgkin's disease remains controversial. To provide further information on the issue, we analysed data of a case-control study from northern Italy. The cases were 158 patients with incident, histologically confirmed Hodgkin's disease, and the controls were 316 patients, frequency-matched to the cases by age, sex and study centre, and admitted to the same network of hospitals for acute, non-neoplastic, non-alcohol- or non-tobacco-related conditions. Compared with those who had never smoked, the multivariate odds ratio was 0.54 for former and 0.85 for current smokers. No trend in risk was found for either the number of cigarettes smoked or the duration of consumption. None of the estimates, or the corresponding trends in risk, was statistically significant. Our results are consistent with those of several studies indicating no direct association between cigarette smoking and risk of Hodgkin's disease.

Abstract
Natural building materials, characterised by middle-low-activity concentrations of primordial radionuclides ((40)K, (232)Th and (238)U series) are widely used in Italy. Since natural materials reflect the geological variability of their sites of origin, a systematic study was carried out in the province of Rome and the results are reported in this paper. In the present work, in order to evaluate average, minimum and maximum contents of primordial radionuclides, more representative lithologies outcropping on the territory of the province of Rome were identified and around 150 samples were collected. Also, these lithologies were characterised from a radioprotection point of view, by means of the evaluation of the index, I, when they are used as building materials. The results confirm the high-primordial radionuclide content within some materials used in Latium (central Italy). Although the study was carried out in a limited area, the results confirm considerable variation in the primordial radionuclide content depending on the sites of origin.

Abstract
The relation between post-menopausal hormone replacement therapy (HRT) and lymphoid neoplasms was analysed using data from a case-control study conducted in northern Italy between 1983 and 1992. Cases included 26 incident, histologically confirmed, post-menopausal female patients of Hodgkin's Disease (HD), 145 non-Hodgkin's lymphomas (NHL) and 65 multiple myelomas (MM), between 45 and 79 years of age. The control group comprised 361 women (age range 45-79 years) admitted to the same network of hospitals for acute, non-neoplastic conditions. The multivariate odds ratio (OR) for ever HRT users was 0.7 [95% confidence interval (CI) 0.2-2.8] for HD, 0.7 (95% CI 0.3-1.4) for NHL, and 0.2 (95% CI 0.1-1.0) for MM. No clear pattern of association was found for duration or recently of use. Despite the relatively small number of cases, due to the rarity of the disease, and the low frequency of HRT use in this population, these findings provide additional information for any global risk-benefit assessment of HRT use.

Abstract
There are appreciable differences in total fluid intake at the individual and population level, and substantial difficulties in obtaining valid measures of fluid intake. Epidemiological studies have examined the association between fluid intake and different types of cancer. For bladder cancer, fluid consumption has been associated with a moderate increase of risk in some studies, including a multicentric case-control study from the United States, based on about 3000 cases, with a decrease in others, including the Health Professional Follow-up study, or with no material association. The evidence, therefore, is far from consistent. Sources and components of fluids were also different across different types studies. From a biological point of view, a decreased fluid intake could result in a greater concentration of carcinogens in the urine or in a prolonged time of contact with the bladder mucosa because of less frequent micturition. Carcinogenic or anticarcinogenic components of various beverages excreted in the urine may also play a role in the process. It has been suggested that fluid consumption has a favorable effect on colorectal cancer risk. Fluid intake may reduce colon cancer risk by decreasing bowel transit time and reducing mucosal contact with carcinogens. Low fluid intake may also compromise cellular concentration, affect enzyme activity in metabolic regulation, and inhibit carcinogen removal. However, epidemiological data are inadequate for evaluation. Data are sparse and inconsistent for other neoplasms, including breast cancer. The fluid constituent of foods, confounding, interactions and possible influences of specific types of beverages should be investigated further. In conclusion therefore the association between total fluid intake and cancer risk remains still open to debate.

Abstract
BACKGROUND Tobacco smoking is one of the main risk factors for oral, pharyngeal and oesophageal cancers in developed countries. Information on the role of the tar yield of cigarettes in upper digestive tract carcinogenesis is sparse and needs to be updated because the tar yield of cigarettes has steadily decreased over the last few decades. PATIENTS AND METHODS We analysed two case-control studies, from Italy and Switzerland, conducted between 1992 and 1999, involving 749 cases of oral and pharyngeal cancer and 1770 controls, and 395 cases of squamous-cell oesophageal carcinoma and 1066 matched controls. Odds ratios (ORs) were estimated by unconditional multiple logistic regression models, including terms for age, sex, study centre, education and alcohol consumption. RESULTS Based on the brand of cigarettes smoked for the longest time, the multivariate ORs for current smokers compared with never smokers were 6.1 for <20 mg and 9.8 for >or=20 mg tar for oral and pharyngeal neoplasms, and 4.8 and 5.4 for oesophageal cancer, respectively. For the cigarette brand smoked in the previous six months, the ORs for >or=10 mg compared with <10 mg were 1.9 for cancer of the oral cavity and pharynx and 1.8 for oesophageal cancer, after allowance for number of cigarettes and duration of smoking. CONCLUSIONS The present study confirms the direct relationship between the tar yield of cigarettes and upper digestive tract neoplasms, and provides innovative information on lower tar cigarettes, which imply reduced risks compared with higher tar ones. However, significant excess risks were observed even in the lower tar category, thus giving unequivocal indications for stopping smoking as a priority for prevention of upper digestive tract neoplasms.

Abstract
A case-control study was conducted in Italy and Switzerland between 1992 and 2000 on 527 cases of laryngeal cancer and 1,297 hospital controls. The risk of laryngeal cancer steadily decreased from 3 years after stopping smoking. Some decline in risk was observed only 20 years or more after stopping drinking.

Abstract
Most up-to-date information on oral contraceptives (OCs) and breast cancer risk comes from a collaborative re-analysis of individual data on 53297 cases and 100239 controls. It is now established that there is a moderately increased breast cancer risk among current OC users, which tends to level off in the few years after stopping use. With regard to cervical cancer, OC use has been found to be associated with increased risk in human papilloma virus-positive women. With reference to the well known protective effects of OCs against endometrial carcinogenesis, additional information has suggested a consistent protection across types of OCs used. Further data on ovarian cancer confirm that the protection of OCs is long lasting, and may well be observed 15 to 20 years after stopping use. Several studies have suggested an inverse relationship between use of OCs and risk of colorectal cancer, and in a meta-analysis of published data the pooled relative risk of colorectal cancer for DC ever-use was 0.82 (95% confidence interval 0.74 to 0.97). There was no association with duration of use. The increased risk for hepatocellular carcinoma in the absence of hepatitis B viruses is the only established evidence of a direct association between OC use and cancer risk, which led an International Agency for Research on Cancer Working Group to classify OCs as carcinogenic to humans in 1998.

Abstract
There is a growing interest in indoor air quality for a better quality environment both at home and at work because many people spend at least 80% of their time indoors. The aim of our study was to evaluate the indoor concentration of airborne bacteria and fungi in a University auditorium, in an office of public buildings and in an apartment in the presence and in absence of building's occupants, building materials and furnishings. The concentrations of airborne bacteria and fungi were determined using a Surface Air System (SAS). In presence of people and furnishings the average air concentrations of bacteria (University auditorium: 925-1225 CFU m(-3); office: 493 CFU m(-3); apartment: 92-182 CFU m(-3)) were higher than in absence (respectively: 190-315 CFU m(-3); 126 CFU m(-3); 66-80 CFU m(-3)). The average air concentrations fungal were higher in presence of people and furnishings (University auditorium: 1256-1769 CFU m(-3); office: 858 CFU m(-3); apartment: 147-297 CFU m(-3)) than in absence (respectively: 301-431 CFU m(-3); 224 CFU m(-3); 102-132 CFU m(-3)). The obtained data can be considered as a step to identify acceptable levels for bioaerosols in common indoor environments.

Abstract
BACKGROUND Case-control studies have suggested that a diet rich in fresh fruit and vegetables protects from the risk of most common epithelial cancers, including those of the digestive tract, and also several nondigestive neoplasms; however, selections in cohort studies have been generally weaker. AIM OF THE STUDY To review the relation between frequency of consumption of vegetables and fruit, estimated intake of selected antioxidants and the risk of cancer at different sites. METHODS Systematic overview of data, with specific focus on a network of case-control studies conducted in Italy from 1983 to 1999. RESULTS The relative risks (RR) of digestive tract neoplasms were reduced in subjects reporting highest vegetable intake. A protective effect of vegetables was also observed for hormone-related neoplasms. Fruit was related to a reduced RR of cancers of the upper digestive tract, stomach and urinary tract. With reference to the role of selected antioxidants, beta-carotene, vitamins C and E showed a significant inverse relation with oral and pharyngeal, esophageal and breast cancer risk. Against colorectal cancer, the most consistent protective effects were provided by carotene, riboflavin and vitamin C, but inverse relations were observed also for calcium and vitamin D. CONCLUSIONS Fruit and vegetable consumption in Mediterranean populations appears to provide protection against several types of neoplasms.

Abstract
Most epidemiological data suggest a protective role for fruits and vegetables in the prevention of several common epithelial cancers, including digestive and major non-digestive neoplasms. The relation between frequency of consumption of vegetables and fruit and cancer and myocardial infarction risk was analysed using data from a series of case-control studies conducted in Italy. For digestive tract cancer, population attributable risks for low intake of vegetables and fruit ranged between 15 and 40%. A selected number of antioxidants showed a significant inverse relation with breast and colorectal cancer risk, although the main components responsible for the favourable effect of a diet rich in vegetables and fruit remain undefined. Fish tends to be another favourable indicator of reduced cancer risk. In contrast, subjects reporting frequent red meat intake showed a relative risk consistently above unity for several common neoplasms. Whole grain food intake was consistently related to reduced risk of several types of cancer, particularly of the upper digestive tract neoplasms. Epidemiological evidence of the relation between fiber and colorectal cancer indicated a possible protections. In contrast, refined grain intake was associated to increased risk of different types of cancer, pointing to a potential role of insulin-like growth factor 1 (IGF-1). A low risk diet for cardiovascular disease includes high consumption of fish, vegetables and fruit, and hence rich in ascorbic acid and other antioxidants, thus sharing several aspects with a favourable diet for cancer.

Abstract
The amount of airborne lead absorbed by the body during occupational exposure depends not only on lead concentration in workplace air, but also on the granulometric distribution of the aerosol. The Occupational Safety and Health Administration (OSHA) set the lead Permissible Exposure Limit (PEL) at 50 micrograms/m3 on the basis of Bernard's model and a number of assumptions, including assumption "C", which predicts that the first 12.5 micrograms/m3 are made up of fine particles (aerodynamic diameter < 1 micron) whereas the remaining 12.5 micrograms/m3 consist of particles > 1 micron. Occupational exposure to airborne lead at a concentration of 50 micrograms/m3 and a granulometric distribution calculated according to the above mentioned assumption, leads, in the model, to a mean blood level of 40 micrograms/dl. In the present study, we tested the validity of assumption "C" in the environmental air of a factory that manufactured crystal glassware containing 24% lead oxide. An 8-stage impactor was used to measure the particle size of airborne dust collected from personal and area samplings. Results indicate that, on the whole, assumption "C" cannot be considered valid in the work environment investigated in this study. As a result, lead absorption levels in exposed workers may be noticeably different from those predicted by the OSHA model. We therefore suggest that in order to make a correct evaluation of the risk of occupational exposure to lead, it is essential to integrate total airborne lead concentration with a measurement of the granulometric distribution of the aerosol.

Abstract
OBJECTIVES The goal of this study was to determine the role of nuclear imaging in patients with chest pain. BACKGROUND The diagnosis of myocardial ischemic events in patients with chest pain and a nondiagnostic electrocardiogram (ECG) is problematic. METHODS Rest tomographic technetium-99m sestamibi imaging (740 MBq intravenously) was performed in 64 patients presenting to the emergency room with chest pain of suspected cardiac origin and a nondiagnostic ECG. Patients were admitted to the coronary care unit on the basis of clinical criteria only and were strictly monitored. RESULTS Thirty patients showed a perfusion defect on admission. Of these, 13 developed myocardial infarction within 12 h. Coronary artery disease was diagnosed in 14 patients and the remaining 3 patients were classified as having false positive findings. Normal perfusion scans were seen in 34 patients, none of whom were ultimately diagnosed as having coronary artery disease. A 100% sensitivity was demonstrated versus the final diagnosis of acute cardiac ischemia (kappa 0.91, 95% confidence interval 0.8 to 1.0). A follow-up period of up to 18 months (mean 11 +/- 3) was also carried out for major cardiac events (death, myocardial infarction, coronary angioplasty and coronary artery bypass grafting). Six events (two coronary bypass procedures, three angioplasty procedures and one death) were observed at follow-up in the group of patients with a technetium-99m sestamibi perfusion defect. Patients with normal perfusion scans on admission had no major cardiac events at follow-up study. CONCLUSIONS Technetium-99m sestamibi perfusion imaging is a promising technique for ruling out acute myocardial ischemia in the emergency room. More efficient utilization of intensive therapy beds may be expected with this approach.

Abstract
ELISA has been used for the detection of IgG antibodies against PPD in 48 patients with pulmonary tuberculosis, in 10 individuals with previously treated tuberculosis and clinically recovered, in 22 PPD skin-test positive healthy volunteers and in 48 blood donors with unknown PPD skin-test. Positivity was obtained in 29 patients (83%) with active tuberculosis, in one patient (10%) with clinical recovery, in none of the healthy controls. This technique may have a potential diagnostic relevance in evaluating patients with suspected pulmonary tuberculosis.

Abstract
The prognostic value of early clinical history, exercise testing and ambulatory electrocardiography was assessed in 263 men (mean age 50 years) recovering from an uncomplicated myocardial infarction (MI). During a mean follow-up period of 31 months, 11 patients died of cardiac causes, 22 developed a non fatal recurrent MI, 16 unstable angina (UA) and 16 underwent coronary artery bypass surgery. The appearance at the exercise stress test of an ischemic S-T segment depression of 0.2 mV or greater (P less than 0.001) as well as the achievement of a work load of 360 Kg-m/m' or less (P less than 0.01) and of a rate-pressure product of 200 Units or less (P less than 0.01), were found to be predictive of the future development of UA, but neither of cardiac death nor of non fatal recurrent MI. The ischemic response was also seen to be predictive of cardiac death (P less than 0.05). S-T segment depression of 0.1 mV or greater, angina and ventricular ectopic activity during the stress test and clinical history were not of predictive value. Complex ventricular ectopic activity (multiform extrasystoles, couplets and ventricular tachycardia) recorded during 24 hour ambulatory electrocardiogram was seen to be predictive of death and non fatal MI. Whereas some parameters such as the ejection fraction and the extension of coronary artery disease are generally accepted as good predictors for cardiac events, others, such as those derived from exercise testing, history and ambulatory electrocardiography may change their predictive value from one survey to another. These discrepancies are due to differences in patient characteristics, in methodology and in medical management.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The authors would first like to stress the increasing frequency of bronchial asthma during or after influenza. To find an explanation for this occurrence they observed tissue reactions following an injection of viral material. In their experiments, they injected into the skin of guinea pigs, strains of the Hong Kong, Texas and USSR influenza viruses using current vaccines, sacrificing groups of animals 2, 6, 24, 48 hours and 7 days after the injection. The histological study revealed the following picture of reaction to influenza viruses. Two hours after the injection: marked and diffuse infiltration of eosinophils in the connective tissue of the skin. After 6 hours: the infiltration shows a predominance of neutrophils. After 24 hours: the neutrophil infiltration is predominant and diffuse. There is evidence of considerable degranulation of eosinophils. The cutaneous histiocytes undergo fibrocytic and marcophagic proliferation. After 28 hours, the same picture. After 7 days there is sever degeneration with a peripheral fibroblastic reaction. The most important finding of this experiment is the early marked infiltration of eosinophils which follows the injection of the influenza viruses. The eosinophil infiltration appears to be related to the release of histamine caused by influenza viruses. The histological examination did not reveal the presence of immune allergic-type cells at any time. Therefore, the onset of asthmatic attacks would appear to be more related to the histamine-releasing action of the influenza viruses rather than to their sensitizing activity. Naturally, the latter may occur in human pathologies.
