Abstract
Despite major advances in genome technology and analysis, >50% of patients with a neurodevelopmental disorder (NDD) remain undiagnosed after extensive evaluation. A point in case is our clinically heterogeneous cohort of NDD patients that remained undiagnosed after FRAXA testing, chromosomal microarray analysis and trio exome sequencing (ES). In this study, we explored the frequency of non-random X chromosome inactivation (XCI) in the mothers of male patients and affected females, the rationale being that skewed XCI might be masking previously discarded genetic variants found on the X chromosome. A multiplex fluorescent PCR-based assay was used to analyse the pattern of XCI after digestion with HhaI methylation-sensitive restriction enzyme. In families with skewed XCI, we re-evaluated trio-based ES and identified pathogenic variants and a deletion on the X chromosome. Linkage analysis and RT-PCR were used to further study the inactive X chromosome allele, and Xdrop long-DNA technology was used to define chromosome deletion boundaries. We found skewed XCI (>90%) in 16/186 (8.6%) mothers of NDD males and in 12/90 (13.3%) NDD females, far beyond the expected rate of XCI in the normal population (3.6%, OR = 4.10; OR = 2.51). By re-analyzing ES and clinical data, we solved 7/28 cases (25%) with skewed XCI, identifying variants in KDM5C, PDZD4, PHF6, TAF1, OTUD5 and ZMYM3, and a deletion in ATRX. We conclude that XCI profiling is a simple assay that targets a subgroup of patients that can benefit from re-evaluation of X-linked variants, thus improving the diagnostic yield in NDD patients and identifying new X-linked disorders.

Abstract
The Lynch syndrome (LS) is an autosomal dominant condition usually characterized by germline pathogenic variants in DNA mismatch repair (MMR) genes. Despite the guidelines now available, determining the pathogenicity of rare variants remains challenging, as the clinical significance of a genetic variant could be uncertain, but it may represent a disease-associated variation in the aforementioned genes. In this case report we will describe the case of a 47 years-old female affected by endometrial cancer (EC) with an extremely rare germline heterozygous variant in the MSH2 gene (c.562G > T p. (Glu188Ter), exon 3) that is likely pathogenic, and a family history consistent with LS.

Abstract
To evaluate the influence of a different order of dentin and enamel layers on stratification appearance of different resin composites. 144 Dentin (D) and Enamel (E) composite samples (Clearfil Majesty ES-2 Premium, Brilliant EverGlow, Estelite Asteria), 1 mm thick, were divided into 12 configurations for each composite, with Enamel-Dentin-Dentin-Enamel (EDDE) assumed as target. The colour specification was conducted using a spectrophotometer, elaborating the results with the CIE L*a*b* colour coordinates and calculating the colour difference in terms of [Formula: see text] quantity. A value of this last major of 3.3 was considered not clinically acceptable. Moreover, data were analyzed using two-way analysis of variance and Tukey post hoc test (P < 0.05). For Clearfil Majesty ES-2 Premium and Brilliant EverGlow, six configurations showed [Formula: see text] > 3.3 compared to gold standard EDDE. [Formula: see text] was influenced especially by b* and L* coordinates (P < 0.05). EDED showed no visual difference (0 < [Formula: see text] < 1.1) for both composites. For Estelite Asteria, two configurations reported [Formula: see text] > 3.3 compared to EDDE. In particular, the L* coordinate influenced [Formula: see text] results (P < 0.05). EDDD was the best configuration (0 < [Formula: see text] < 1.1). Within the limits of a vitro study, Brilliant EG showed more dependence from order and thickness of stratification (resulting more similar to Clearfil Majesty ES-2 Premium); therefore, it could be indicated for more complex aesthetic restorations. Estelite Asteria seems to be able to balance small differences in thickness of dentin and enamel layers, and consequently, it is more indicated to different clinical situations.

Abstract
Only a few Herculaneum rolls exhibit writing on their reverse side. Since unrolled papyri are permanently glued to paperboard, so far, this fact was known to us only from 18th-century drawings. The application of shortwave-infrared (SWIR; 1000-2500 nm) hyperspectral imaging (HSI) to one of them (PHerc. 1691/1021) has revealed portions of Greek text hidden on the back more than 220 years after their first discovery, making it possible to recover this primary source for the ongoing new edition of this precious book. SWIR HSI has produced better contrast and legibility even on the extensive text preserved on the front compared to former imaging of Herculaneum papyri at 950 nm (improperly called multispectral imaging), with a substantial impact on the text reconstruction. These promising results confirm the importance of advanced techniques applied to ancient carbonized papyri and open the way to a better investigation of hundreds of other such papyri.

Abstract
INTRODUCTION The Mayo technique is one of the most common techniques used to repair incisional, umbilical, and epigastric hernias. A high percentage of recurrences, together with the use of particular expensive types of meshes, are some of the most relevant problems in this surgical field. PATIENTS AND METHODS This study is a clinical prospective observational and involves all the patients who underwent procedures using a new modified Mayo technique from 2006 through 2013. The general criteria analyzed were age, sex, obesity, smoke abuse, diabetes, chronic diseases, type of hernia, operative time, morbidity and mortality. All the patients involved in this study were followed-up from 6 to 120 months. RESULTS The types of hernia were 5 epigastic hernia (20,8%), 8 umbilical hernia (33,3%), 11 midline incision hernia (45,9%). Ten patients (41,7%) presented non-complicated hernias; 8 patients (33,3%) presented strangulated hernias and 6 patients (25,0%) presented obstructed hernias. No intestinal resection was necessary in any of the patients. The mean operative time was 55 minutes (range 30-180). The mean hospital stay of the patients' after-post operative procedure was 4.5 days (range, 2 to 8 days). No major complications have been reported. Only one patient present a recurrence. CONCLUSION These preliminary results suggest that this modified Mayo technique could be useful in the armamentarium of surgeon to repair incisional, umbilical, and epigastric hernias. More studies are needed to validate the technique.

Abstract
We estimated the serum levels of SCC-Ag, CEA and TPA in 69 patients with head or neck neoplasia and 31 healthy patients using a radioimmunometric method (double antibody). SCC-Ag concentrations were significantly increased in 43.4% cancer patients with respect to the cut-off point value (1.7 ng/ml) of the control group, and the specificity was 96.7%. The data varied according to the evolutive phase of disease. Since the combined evaluation of SCC-Ag, TPA and CEA serum levels increased the sensitivity, that was 71.0%, we thought it opportune to use all these markers in the tumoral pahtology taken into consideration.

Abstract
Because of its physical and potassium-metabolic characteristics 201T1 is more suitable than 131Cs for radioisotopic studies of the cold thyroid nodule, with the further diagnostic possibility of quantitatively assessing intranodular behaviour for a specific differentiation among different kinds of neoformations. Using a gamma-camera on line with a computer data processing device, sequential scintiscans were recorded for the first 20-30 min after i. v. administration of 15-20 MCi\lkg of radiothallium; delayed sequences were taken at 40-60 min if intranodular uptake appeared. A quantitative appraisal was made of the differential 201Tl uptake-ratio between nodule and healthy thyroid tissue (density-index) and the multiparameter analysis of thyroid time/activity curves generated on the relative regions of interest (ROIs). This computerized study, in 120 out of 293 patients submitted to this radiothallium test, has shown a) diagnostic agreement between clinical-histological and radioisotopic findings in 76 out of 79 colloid-cystic or degenerative neoformations, in all 16 malignant and in 23 out of 25 hyperplastic benign nodules; b) significant statistical difference of the density-index in solid versus cystic but not between benign and malignant nodules; c) different 201T1 kinetics behaviour in different kinds of solid thyroid lesions with a satisfactory statistical difference of the radiothallium nodular dissapearance-index.

Abstract
PURPOSE Papillary thyroid carcinoma (PTC), the most common thyroid cancer histotype, has a good prognosis even when spread to the neck lymph node (LN). The prognostic role of LN metastases' location is still controversial. The aim of the present study was to evaluate the clinical relevance of the number and location of LN metastases at presentation in PTCs. METHODS This retrospective study included a consecutive series of 1653 PTC patients followed for a mean period of 5.9 years in a referral thyroid cancer clinic. All patients have undergone thyroidectomy with the dissection of at least six LNs. According to the LN status, patients were subdivided into 569 N0 (34.4%), 644 N1a (39.0%, central compartment) and 440 N1b (26.6%, latero-cervical compartment). RESULTS Age at diagnosis was significantly lower in N1b (39.8, IQR 30.7-51.6) and N1a (40.1, IQR 31.3-50.1) than in N0 (44.7, IQR 36.6-55.0 yrs). The male gender was more prevalent in N1b than in N1a and N0 (F/M = 1.9/1, 4.0/1 and 5.5/1, respectively). Persistent/recurrent disease at last control was significantly more frequent in N1b (29.8%) than in N1a (14.3%), and in N1a than in N0 (4.2%) (p < 0.01 for all). Also, distant metastases were significantly (p < 0.001) more frequent in N1b (14.1%) than in N1a (4.3%) and N0 (1.6%). LN metastases' number (>5) was a significant risk factor for persistent/recurrent disease only for N1a patients. CONCLUSIONS These data indicate that persistent/recurrent disease and distant metastases are significantly more frequent in patients with latero-cervical LN (N1b) metastases and that the LN location should be used for a better postsurgical risk stratification.

Abstract
BACKGROUND To reduce the rate of recurrence of incisional hernia repair associated with open anatomic techniques, we present an experimental study, focusing on two different sutures, with the aim to apply clinically in a revised version of the Mayo technique. METHODS Thirteen biological tissue samples from adult pig central brawn and upper and lower fasciae were measured using two techniques defined as "unbroken suture thread" and "separated suture stitches" to test the breaking resistance of the two types of suture. RESULTS The t test results show that the two sets can be considered as different populations. The mean tensile stress max is greater (with reduced deviation) for the specimens of the set sutured with unbroken thread technique. Student's t-test performed on values obtained for each set of samples indicated that the unbroken thread suture technique corresponds to higher ultimate failure strength. CONCLUSION Considering these results, a modified Mayo technique with continuous closure could be suggested. Of course a valid clinical study is required to better clarify this experimental hypothesis.

PURPOSE Psychiatric disorders could affect the patients' abilities to cope with diabetes. The objectives of this study were to assess the prevalence of depression and alexithymia among type 2 diabetic patients and investigate the possible correlations between these psychopathological phenomena and glycaemic control assessed through glycated hemoglobin (HbA1c). METHODS All the patients were evaluated through 20-item Toronto Alexithymia Scale (TAS-20), Hamilton rating scale for depression and Quality of Life Index. HbA1c values, diabetes duration, therapy and socio-demographic characteristics were recorded. RESULTS One hundred and twenty-eight patients (75 males and 53 female, mean age 64.7 ± 11.2 years) were enrolled. Alexithymic patients, compared to non-alexithymic ones, presented a significantly higher HbA1c (7.7 ± 1.5 vs. 7 ± 1.5, p = 0.016). No statistically significant difference was found when comparing the HbA1c of depressed versus non-depressed patients. Considering the raw values of HbA1c, the higher percentage was recorded among patients suffering from depression plus alexithymia (comorbidity group) followed by patients presenting alexithymia only, patients with neither depression nor alexithymia (control group) and, finally, those presenting depression only. The comorbidity group presented a significantly higher value of HbA1c (7.7 ± 1.2) than the control group (7 ± 1.6, p < 0.04) and the depressed patients (6.9 ± 1.3, p = 0.04). At the logistic regression, the HbA1c was found to be significantly associated only with alexithymia (TAS-20 total score) and insulin therapy. CONCLUSIONS Alexithymia more than depression influences glycaemic control. When evaluating a diabetic patient, a rapid screening for psychopathological alterations would guarantee a more accurate management. The treatment of any associated psychiatric disorders would improve the patients' quality of life.

Abstract
BACKGROUND AND AIMS Due to the worldwide increasing prevalence of diabetes (DM), patients with both diabetes and Graves' disease (GD) have become more frequent. Sporadic reports indicate that Graves' orbitopathy (GO), a GD complication that affects orbital soft tissues, can be severe in DM patients. The relationship between these diseases is not well understood. This study aims at evaluating the association of GD and GO with autoimmune and non-autoimmune diabetes (DM) and to assess diabetic features that influence GD and GO prevalence and severity. METHODS AND RESULTS This retrospective study evaluated GD, GO and DM association in 1211 consecutive GD patients (447 with GO and 77 with DM). A case-control study was carried out to evaluate DM relationship with GO severity by comparing at 1:2 ratio GO patients with or without DM. A strong association was found between GD and T1DM (p = 0.01) but not T2DM. Instead, the presence of GO was strongly associated with T2DM (p = 0.01). Moreover, GO was more frequently severe in GD patients with T2DM (11/30 or 36.6%) than in those without T2DM (1/60 or 1.7%, p = 0.05). T2DM was the strongest risk factor for severe GO (OR = 34.1 vs. 4.4 p < 0.049 in cigarette smokers). DM duration, obesity and vascular complications, but not metabolic control were significant determinants of GO severity. CONCLUSIONS GD is associated with T1DM but not with T2DM, probably because of the common autoimmune background. GO, in contrast, is more frequent and severe in T2DM, significantly associated with obesity, diabetes duration and diabetic vasculopathy but not metabolic control.

Abstract
OBJECTIVES Across Europe, more than one third of patients are diagnosed with HIV infection late. Late presentation for care has been associated with higher risk of clinical progression and mortality. In the present study, we evaluated the prevalence, epidemiological characteristics and survival probability of patients with late and very late presentation, newly diagnosed with HIV infection in Catania, Italy, from 1985 to 2010. PATIENTS AND METHODS According to the European Consensus definition, Late Presenters (LP) were defined as subjects presenting for care with a CD4+ T-cell count below 350 cells/µl or with an AIDS-defining event, regardless of CD4+ T-cell count; patients with advanced HIV disease (Very Late Presenters) (VLP) were those presenting with a CD4+ T-cell count below 200 cells/µl or with an AIDS-defining event, regardless of CD4+ T-cell count. RESULTS 620 patients were included in the study. 345 (55.6%) subjects were LP, 35% of them were asymptomatic; 246 (39.7%) were VLP. In univariate analysis, late presentation was related to age (p < 0.001), to heterosexual exposure to HIV infection (70% of heterosexual subjects were LP) (p < 0.005) and to being diagnosed during the calendar period from 1991 to 2000 (p < 0.001). Very late presentation was related to age (p < 0.001), male sex (p < 0.01), heterosexual risk (p < 0.001) and to being diagnosed during the calendar period from 1991 to 2000 (p < 0.001). In multivariate analysis, age (p < 0.0001), being older than 50 years old (p = 0.02), years of diagnosis 1991-1995 (p < 0.005) and 1996-2000 (p < 0.05) in the subgroup of late presenters and age (p < 0.0001), being older than 50 years old (p < 0.005), male sex (p < 0.0001), years of diagnosis 1991-1995 (p < 0.05) and 1996-2000 (p < 0.005) in the subgroup of very late presenters maintained statistical significance. The survival probability within LP and VLP group was statistically lower than no LP/VLP (log rank test p < 0.0005 and p < 0.0001, respectively). For both LP (p < 0.002) and VLP (p < 0.0001), survival probability was significantly lower in the pre-HAART era, in comparison with the period of mono/dual therapy and the HAART era. CONCLUSIONS More than fifty percent of patients in our setting were diagnosed late with HIV infection and, consequently, treated late. Late and very late presentation were associated with lower survival probability. The implementation of strategies focused on targeted prevention efforts and HIV testing programs appears fundamental to diagnose and treat HIV infection as early as possible.

Abstract
AIM Vitamin D deficiency is very common among HIV-infected subjects. We cross-sectionally evaluated the prevalence and risk factors for hypovitaminosis D in 91 HIV-infected Italian patients. PATIENTS AND METHODS We studied in a cohort of 91 HIV-infected Italian patients the metabolism of Vitamin D by evaluating the in vitro expression of CYP27B1, CYP24A1 and vitamin D receptor (VDR) by monocytes and macrophages stimulated with the viral envelope protein gp120 or lipopolysaccharide (LPS). RESULTS The prevalence of vitamin D deficiency (25OHD < 10 ng/ml) and vitamin D insufficiency (25OHD 10-30 ng/ml) was 31% and 57%, respectively. In univariate analysis, female sex (p = 0.01), increasing age (p = 0.05), higher highly sensitive-C reactive protein (p = 0.025), higher parathyroid hormone (PTH) (p = 0.043) and lower BMI (p = 0.04) were associated with vitamin D deficiency. In multivariate analysis, the association was still significant only for PTH (p = 0.03) and female sex (p = 0.03). Monocyte stimulation with LPS (100 ng/ml) or gp120 (1 µg/ml) significantly upregulated CYP27B1 mRNA expression. Moreover, gp120 significantly increased VDR mRNA levels. On the contrary, neither LPS nor gp120 modified CYP24A1 levels. Macrophage stimulation with LPS (100 ng/ml) significantly upregulated CYP27B1 and CYP24A1 mRNA expression. When monocytes were cultured in the presence of 25OHD (40 ng/ml) and stimulated with LPS we detected significantly lower levels of 25OHD in the supernatant. CONCLUSIONS Vitamin D deficiency was very common in our cohort of HIV-infected patients. Chronic inflammation, including residual viral replication, may contribute to hypovitaminosis D, by modulating vitamin D metabolism and catabolism. Systematic screening may help identifying subjects requiring supplementation.

Abstract
PURPOSE The purpose of this systematic review is to evaluate and compare the risk of dissemination metastasis (wound, port-side metastases and peritoneal seeding) after laparoscopic colorectal surgery and conventional open surgery for colorectal cancer. MATERIALS AND METHODS The Authors searched relevant randomized controlled trials between January 1998 and July 2012. RESULTS Wound, port-site metastases and peritoneal seeding were rare and no significant differences occurred between the two groups. The port-site and extraction site recurrence were likely to be the results of suboptimal surgical techniques and occurred in the early phase of the learning curve. The authors also found no significant differences in overall, local and distant recurrences. No significant differences between laparoscopic and open surgery were found in cancer-related mortality during the follow up period of the study (7 RCTs, 3525 patients, 12.8% vs. 14.00%; OR (fixed) 0.83, 95% CI 0.68-1.02), with no significant heterogeneity (p = 0.35). CONCLUSIONS The literature supports the implementation of laparoscopic surgery into daily practice. Laparoscopic surgery can be used for safe and radical resection of cancer in the right, left, sigmoid colon and rectum. However further studies should address whether laparoscopic surgery is superior to open surgery in this setting.

Abstract
INTRODUCTION Anxiety disorders are frequent in HIV-infected individuals, can pre-exist or occur during HIV infection. We evaluated with a self-reported questionnaire whether anxiety is related to HIV clinical status and therapeutic success in a cohort of HIV-positive subjects in Sicily. PATIENTS AND METHODS We enrolled 251 patients on combination antiretroviral therapy (cART) for at least six months; Self Rating Anxiety State SAS 054 was used to diagnose anxiety and a Z score ≥ 45 points was considered diagnostic. RESULTS 47% of patients were diagnosed with anxiety. Patients showing symptoms related to anxiety had experienced a high number of therapeutic switches (fourth line or more). CONCLUSIONS These data confirm a high prevalence of anxiety symptoms among subjects with HIV infection in Eastern Sicily. Physicians should be aware of the extent of the problem and should be able to adequately manage anxiety in the setting of HIV infection.

Abstract
AIM To assess resistance to cyclic fatigue of reciprocating nickel-titanium ( NiTi ) files (Reciproc and WaveOne) after immersion in NaOCl solution over several time periods. METHODOLOGY A total of 90 new Reciproc R25 and WaveOne Primary were tested. The 45 files of the same brand were randomly assigned to three groups (n = 15) and submitted to the following immersion protocol in 5% NaOCl at 37 °C for 16 mm: no immersion (control), 1 or 5 min dynamically. The dynamic immersion and the following cyclic fatigue tests were performed using the appropriate preset reciprocation modes ('RECIPROC ALL' or 'WAVEONE ALL') in a specially designed endodontic motor. Resistance to cyclic fatigue was determined by recording time to fracture (TtF) in a stainless steel artificial canal with a 60° angle of curvature and 5 mm radius of curvature. The artificial canal was manufactured reproducing the instrument's size and taper. Data were analysed by 2-way analyses of variance. RESULTS Resistance to cyclic fatigue of the same NiTi file was not significantly affected by immersion in NaOCl . Reciproc R25 was associated with a higher cyclic fatigue resistance in all groups compared to WaveOne Primary (P < 0.0001). CONCLUSIONS Reciprocating dynamic immersion in NaOCl for 1 or 5 min did not reduce the cyclic fatigue resistance of NiTi files significantly. However, the type of reciprocating instrument influenced cyclic fatigue resistance with Reciproc R25 being more resistant than WaveOne Primary.

Abstract
BACKGROUND Italian Legislative Decree No. 81/2008 foresees the involvement of a "specialised physician" in activities for the promotion of health at the workplace. OBJECTIVES These activities are aimed at modifying erroneous lifestyles (such as smoking, drinking, bad diet, etc.) which are responsible for serious illnesses and also for repercussions on the assessment of fitness for a specific task. Obesity, as we know, represents the major risk factor in the onset of metabolic, neoplastic, cardiovascular and respiratory diseases and also in the increased incidence of accidents at the workplace and sick absence. METHODS A specific questionnaire was administered to 700 health care workers of a Hospital in Catania to estimate the incidence of factors which favour the onset of these diseases: factors such as familiarity, endocrinal dysfunction problems (diabetes mellitus, hypothyroidism), shift work and little physical exercise. RESULTS AND CONCLUSION Statistical processing of the data confirmed, partially, that little physical exercise, hypothyroidism, diabetes mellitus, familiarity in the > 36 age group were the major risk factors in the onset of obesity, as reported in the literature. However, contrary to the literature reports, shift work did not seem to be a risk factor in the sample under study. A programme of rehabilitation, on a voluntary basis, will be offered to those workers who are overweight/obese. This programme will involve professionals such as nutritionists, endocrinologists and psychologists, and it will aim at improving workers' health conditions as well as their work performance.

Abstract
BACKGROUND AND AIMS Metabolic syndrome (MS) has been mainly related to insulin resistance, but the role of changes in insulin secretion has not been thoroughly investigated. METHODS AND RESULTS Using an oral glucose tolerance test (OGTT) we studied beta-cell function and insulin sensitivity in subjects with normal fasting glucose with and without MS, and their relationship to fatty liver which was evaluated by abdominal-ultrasonography. In MS early phase insulin secretion, as measured by insulinogenic index (IG(30)), was increased (p<0.05) independently from insulin sensitivity. Furthermore IG(30) was progressively higher as the number of factors needed for the diagnosis of MS increased (p<0.01). Insulin and C-peptide AUC were also increased (p<0.01 and p<0.05, respectively) but, in contrast to IG(30), these differences disappeared when ISI was used as a covariate. After OGTT, 51% of the subjects with MS had altered post-load glucose tolerance compared to 24.9% without MS (p<0.01). In both groups, the altered glucose tolerance was associated with a similar IG(30) reduction. In normo-tolerant subjects with MS the IG(30) was higher (+54.1%, p<0.01), and this elevation occurred irrespective of ISI; however, the beta-cell compensatory capacity for insulin resistance (disposition index) was impaired (p<0.001). Fatty liver was more frequent (p<0.001) and more severe (p<0.01) in MS, and it was significantly related to total AUC-insulin (p<0.001), independently from ISI. CONCLUSION These findings indicate that the prevalence of altered tolerance is more frequent in subjects with normal fasting glucose and MS. The hyperinsulinemia might not only be an adaptive response to insulin resistance, but a primary defect of beta-cell function contributing to glucose intolerance.

Abstract
OBJECTIVE To evaluate the efficacy of probiotics in the prevention of gastrointestinal colonization by Candida species, of late-onset sepsis and neurological outcome in preterm newborns. STUDY DESIGN A prospective study was conducted in 249 preterms who were subdivided into three groups: one group (n=83) was supplemented with Lactobacillus (L.) reuteri, one group with L. rhamnosus (n=83) and the other with no supplementation (n=83). The fungal colonization in the gastrointestinal tract, the late onset of sepsis and clinical parameters were recorded. A neurological structured assessment was further performed at 1 year of age. RESULT Candida stool colonization was significantly higher (P<0.01) in the control group than in the groups treated with probiotics. The L. reuteri group presented a significantly higher reduction in gastrointestinal symptoms than did the L. rhamnosus and control groups. Infants treated with probiotics showed a statistically significant lower incidence of abnormal neurological outcome than did the control group. CONCLUSION The use of both probiotics seems to be effective in the prevention of gastrointestinal colonization by Candida, in the protection from late-onset sepis and in reducing abnormal neurological outcomes in preterms.

Abstract
BACKGROUND Vascular damage of frontal-subcortical circuits involved in mood regulation and cognition might be the main contributor to the pathogenesis of late-life depression, and it is linked to poor response to treatment. OBJECTIVE To investigate the relationship between executive dysfunction and outcome of depressive symptoms among elderly patients with subcortical ischemic vascular disease. METHODS Ninety-two elderly patients with white matter lesions (WMLs) or lacunar infarcts (LAs) on brain MRI and depressive symptomatology were consecutively recruited. Depression was rated with the Hamilton Depression Rating Scale (HDRS). Evaluation of executive functions by means of the Stroop color-word test was performed at entry of the study, and WMLs were categorized into mild, moderate or severe. Mood was reevaluated by means of HDRS after the 12th week of pharmacological treatment. RESULTS Psychomotor retardation, difficulties at work, apathy, and lack of insight were the predominant symptoms. Fifty-six patients (62.8%) had a neuroradiological picture of WMLs, while the remaining 33 (37.1%) had LAs. Executive dysfunctions significantly and independently predict poor outcome of depressive symptoms. Patients with the severest WMLs showed not only a greater executive dysfunction, but also a minor response to antidepressant treatment. CONCLUSION This study supports the vascular depression hypothesis. WMLs are of crucial clinical relevance as they are linked with cognitive symptoms and poor antidepressant outcome.

Abstract
There is much concern about the increasing presence in the environment of synthetic chemicals that are able to disrupt the endocrine system. Among these compounds, 4-nonylphenol (4-NP) is one of the most studied xenoestrogens, due to its widespread accumulation in water sediment and consequent presence in fatty acid of aquatic organisms. Here, we have used a zebrafish microarray representing 16,399 genes to study the effects of 4-NP and estradiol-17beta (E2) in adult male zebrafish in order to elucidate the mechanism of action of 4-NP compared with that of E2. The microarray results showed that both 4-NP and E2 induced a strong expression of vitellogenin (VTG), the sex related precursor of the yolk proteins in oviparous vertebrates. Both treatments induced elevated protein turnover upregulating genes involved in proteolysis and those that are constituents of the ribosome. Many genes regulated by 4-NP and E2 are involved in energy metabolism, oxidative stress defense mechanisms, xenobiotic metabolism, and lipid metabolism. A different pattern of expression in the two treatments was found for genes involved in oxidative stress, since E2 seems to induce the mechanism of detoxification, while 4-NP seems to inhibit this protective mechanism of the cell. Overall, these findings demonstrate that the microarray approach can contribute significantly to the understanding of expression patterns induced by E2 and 4-NP in male zebrafish. The results also demonstrate that 4-NP is able to act through an alternative pattern to that of estradiol-17beta, modulating the expression of the same genes in a different manner.

Abstract
Proopiomelanocortin (POMC) is an important gene implicated in different functions, such as the stress response of the hypothalamus-pituitary-adrenal axis. The aim of the present study was to determine whether farming conditions, such as stocking density, can be considered a powerful stressor influencing in turn the growth rate in juvenile fish. Thus, POMC cDNA expression was investigated during adaptation to farming conditions in sole (Solea solea), as a model for studying the effects of rearing densities on stress response; different stocking densities (50, 100, and 250 animals/m(2)) were applied and, after 7 and 21 days, the fishes were examined for body weight and plasma cortisol levels as indicators of stress. In addition, proopiomelanocortin was cloned and sequenced from the brain of sole, allowing semi-quantitative RT-PCR to be performed to evaluate POMC mRNA expression in brain tissue. There was a significant increase in cortisol levels in fish reared at high stocking densities of 250/m(2) compared to fish reared at control densities of 100 and 50/m(2), in both experimental times, i.e., 7 and 21 days. The high stocking densities were also found to decrease the specific growth rate of fish. Moreover, it was demonstrated that the highest stocking density induced a significant decrease in sole POMC mRNA expression. It is concluded that POMC and cortisol are both involved in the stress response due to high rearing densities, during which cortisol may serve as a negative regulator of POMC.

Abstract
The aim of this study was to follow the evolution of neurological findings in a cohort of near-term infants born between 35 and 37 weeks. A total of 448 infants born between 35 and 36.9 weeks gestational age with normal cranial ultrasonograms or only minor abnormalities, were studied using the Hammersmith Infant Neurological Examination, at 6, 9 and 12 months (corrected for prematurity). Our results showed that while some items such as cranial nerve and movements showed minimal changes over time, other items mainly related to "tone", "posture" and "reflexes" showed progressive maturation. There was no significant difference between the infants born at 35 and 36 weeks gestation. When compared to term infants assessed at the same age intervals, our cohort showed a wider variability of scores. Mean and 10 (th) percentile for global scores were lower than those reported for term infants suggesting that when assessing infants born at 35 and 36 weeks the optimality scores used for infants born full-term should not be used as normative data. Our results, providing longitudinal data in near-term infants without brain lesions, can be used as a reference in both clinical and research setting to monitor early neurological signs in those children.

Abstract
PURPOSE The aim of our study was to assess the smoking habits in health care workers. MATERIALS AND METHODS In concomitance with a medical examination for Health Care Surveillance requested by the Italian Laws (D. Lgs. 626/94), our operative units interviewed 2,000 persons (47.9% males, 52.1% females, mean age = 45 yrs (SD+/-9.41 yrs) working in two General Hospitals of Eastern Sicily. RESULTS The prevalence of smokers was found to be higher in men (34.5%) than in women (33.6%), in Health Care Operators (36.4%) and professional nurses (36.2%) than in medical doctors (27.7%), in night-time workers (34,5%) then in day-time-workers (28,7%). The compliance with smoking restriction was found to be poor; in fact, 60% out of smokers declared to smoke during the working hours. CONCLUSIONS This investigation has revealed the significant prevalence of tobacco smoking among the health care workers in general. We think that the inclusion of an anonymous questionnaire on smoking habits within the Services of Sanitary Surveillance may help in the national campaign against cigarette smoking.

Abstract
Many synthetic chemicals, termed xenoestrogens, have been shown to interact as agonists with the estrogen receptor (ER) to elicit biological responses similar to those of natural hormones. To date, the regulation of vitellogenesis in oviparous vertebrates has been widely used for evaluation of estrogenic effects. Therefore, Carassius auratus juveniles were chosen as a fish model for studying the effects of estradiol-17beta and different concentrations (10(-6) and 10(-7) M) of 4-nonylphenol (4-NP) on the expression of liver ERbeta-1 subtype; plasma vitellogenin and sex steroids (androgens and estradiol-17beta) were also evaluated together with the bioaccumulation process, through mass-spectrometry. C. auratus is a species widespread in the aquatic environment and, on the toxicological point of view, can be considered a good "sentinel" species. Juveniles of goldfish were maintained in tanks with only tap water or water with different concentrations (10(-6) and 10(-7) M) of 4-nonylphenol (4-NP), or 10(-7) M of estradiol-17beta. After 3 weeks of treatment, animals were anesthetized within 5 min after capture, and blood was immediately collected into heparinized syringes by cardiac puncture and stored at -70 degrees C; the gonads were fixed, then frozen and stored at -70 degrees C; the whole fish, liver, and muscle tissues were harvested and immediately stored at -70 degrees C for molecular biology experiments and bioaccumulation measurements. The estrogenic effects of 4-NP were evidenced by the presence of plasma vitellogenin in juveniles exposed both to estradiol-17beta and the two doses of 4-NP; moreover, exposure to 4-NP also increased aromatization of androgens, as suggested by decreasing androgens and increasing estradiol-17beta plasma levels. The changes of these parameters were in agreement with the increasing transcriptional rate of ERbeta-1 mRNA in the liver, demonstrating that both estradiol-17beta and 4-NP modulate the vitellogenin rate through interaction with the ERbeta-1 subtype. The present study also suggests that 4-NP at the concentration of 10(-6) M bioaccumulates in the liver.

Abstract
BACKGROUND Environmental factors are believed to play a critical role in the development of allergic respiratory diseases, such as asthma and rhinitis. Particularly, the role of urban pollution in the pathogenesis of these diseases is debated. OBJECTIVES The aim of the study was to investigate whether subjects with a well-defined occupational history of exposure to road traffic fumes presented an increased prevalence of respiratory symptoms of chronic bronchitis (cough), asthma (wheeze), and allergic sensitisation to the most common allergens and reduced lung function compared with an unexposed control group. METHODS The study was conducted on 484 traffic police in Catania (465 men and 19 women), with a mean age of 45 +/- 7.9 years, who were subdivided into three groups. The first group included traffic police assigned to traffic direction, the second group included traffic police working in administrative offices, the third group included all traffic police who did not fall into the previous groups. In the first group, "truly exposed" subjects were identifed as police officers assigned to traffic direction in the last 8 years. Similarly, in the second group, "truly non-exposed" subjects were identified as police officers working in offices in the last 8 years. RESULTS Statistical analysis showed a significant difference in mean age between the truly exposed group and the truly non-exposed group (p < 0.01). The truly exposed group showed a greater prevalence of symptoms (cough, wheeze and dyspnoea), and positive reaction to skin allergy tests compared with the "truly non-exposed group", but this increase did not reach statistical significance. Alterations of the respiratory function tests were more frequent in the non-exposed (14.3%) compared to the exposed group (9.6%). The highest prevalence of cough, dyspnoea and wheezing was detected in smokers compared to non-smokers and to ex-smokers within each group. CONCLUSIONS Our results show a major prevalence of respiratory symptoms and allergic sensitisation in exposed traffic police compared with non-exposed police, although this did not reach statistical significance. Further epidemiological studies conducted on larger samples are required to better understand the role of road traffic pollution in inducing allergic respiratory diseases.

Abstract
BACKGROUND During the natural history of human immunodeficiency virus type I (HIV-1) infection, an impairment of interleukin-12 (IL-12) production precedes a switch from a T-helper 1 (Th1) to a T-helper 2 (Th2) stage of cellular immunity. Melatonin, the main hormone produced by the pineal gland, seems to promote a Th1 response by increasing the production of IL-12 in vitro. The aim of this study was to measure and correlate serum levels of melatonin and IL-12 in a cohort of HIV-1-infected individuals. PATIENTS AND METHODS 77 anti-HIV-1-positive subjects were enrolled: 20 were in CDC stage A, 25 in CDC stage B and 32 in CDC stage C. 30 healthy HIV-1-seronegative subjects were recruited as controls. IL-12 and melatonin concentrations were quantitated in serum samples. RESULTS Mean levels of serum melatonin were significantly lower in HIV-1-infected individuals in comparison with controls (p < 0.001). Within the HIV-1-seropositive group, mean melatonin and IL-12 concentrations were significantly lower in patients in CDC stage C, as compared with patients in CDC stages B and A (p < 0.01). CONCLUSION During the natural history of HIV-1 disease, serum melatonin levels are progressively reduced. This reduction may be related to the impairment of Th1 immunoresponses.

Abstract
BACKGROUND Although exercise training improves exercise tolerance in most patients with chronic obstructive pulmonary disease (COPD), some patients with severe disease may not be able to tolerate exercise training due to incapacitating breathlessness. Transcutaneous electrical muscle stimulation (TCEMS) has been shown to improve muscle strength, muscle mass, and performance in paraplegics, patients with knee ligament injury, and patients with peripheral vascular disease. We hypothesised that TCEMS of the lower extremities can improve muscle strength and exercise tolerance in patients with moderate to severe COPD. METHODS A randomised controlled trial of TCEMS of the lower extremities was performed in 18 medically stable patients of mean (SD) age 60.0 (1.5) years with a mean forced expiratory volume in 1 second (FEV(1)) of 1.03 (0.10) l (38% predicted) and residual volume/total lung capacity (RV/TLC) of 59 (2)%. Stimulation of the lower extremities was performed three times a week, 20 minutes each session, for six continuous weeks. Quadriceps and hamstring muscle strength, exercise capacity, and peak oxygen uptake were measured at baseline and after 6 weeks of stimulation. RESULTS TCEMS improved both the quadriceps strength (by 39.0 (20.4)% v 9.0 (8.1)%, p=0.046) and hamstring muscle strength (by 33.9 (13.0)% v 2.9 (4.7)%, p=0.038) in the treated (n=9) and sham treated (n=9) groups, respectively. The improvement in muscle strength carried over to better performance in the shuttle walk test in the treated group (36.1% v 1.6% in the treated and sham groups respectively, p=0.007, Mann-Whitney U test). There was no significant change in lung function, peak workload, or peak oxygen consumption in either group. Muscle stimulation was well tolerated by the patients with no dropouts and better than 95% compliance with the protocol. CONCLUSIONS TCEMS of peripheral muscles can be a useful adjunct to the comprehensive pulmonary rehabilitation of patients with COPD.

Abstract
BACKGROUND The purposes of this study are: 1) predicting the sum of mesio-distal crown diameters of unerupted canines, first and second premolars, using the sum of mesio-distal diameters of lower permanent incisors, in a sample of Eastern Sicily population; 2) estimating the differences between our predictions and the ones developed by Tanaka & Johnston, by Moyers and by Ballard & Wylie. METHODS We selected 150 plaster casts of permanent dentition of patients - 82 females and 68 males - examined at the School of Orthodontics of the University of Catania. The width of canines, first and second premolars and lower incisors were taken by means of a bow-compass and a sliding digital caliper on the selected plaster casts. RESULTS We calculated the following linear regression equations, with statistical method, to predict the sum of mesio-distal dimensions of canines, first and second premolars (Y) using the width of the lower incisors (X): Yfs = 11.40 + 0.42X for females in the upper arch; Yfi = 11.34 + 0.41X for females in the lower arch; Yms = 12.84 + 0.39X for males in the upper arch and Ymi =11.38 + 0.44X for males in the lower arch. CONCLUSIONS The results in our sample indicate that the sum of mesio-distal crown diameters of canines, first and second premolars is smaller in females than in males; besides those results suggest that the North-American authors' predictions overestimate the mesio-distal dimension of canines, first and second premolars in both sexes.

Abstract
The ability of lung fibroblasts to modulate the immune response has been evaluated by analyzing the synthesis and release of interleukin (IL)-10 and IL-12 by lipopolysaccharide (LPS)-stimulated peripheral blood monocytes exposed to pulmonary fibroblast conditioned medium (FCM). IL-10 and IL-12 contents and gene expression were markedly modified by treatment with FCM as measured by ELISA (+97.5 +/- 12.8% and -68 +/- 7.3% for IL-10 and IL-12, respectively), immunocytochemistry, and reverse transcriptase-polymerase chain reaction (RT-PCR). These effects appeared to be mediated by prostaglandin E(2) (PGE(2)) as the modified release of both cytokines was reduced by treatment with indomethacin and mimicked by addition of exogenous PGE(2.) As a result of the enhanced production of IL-10, exposure of LPS/interferon (IFN)-gamma-activated monocytes to FCM was also able to reduce the expression of the class II major histocompatibility complex (MHC) molecule, human leukocyte-associated antigen-DR (HLA-DR) (-51.8 +/- 8.7%) and of the costimulatory molecule, CD40 (-53.9 +/- 11.7%). The expression of both molecules was completely restored when monocytes were pretreated with a neutralizing anti-IL-10 monoclonal antibody. The FCM obtained from fibrotic lung fibroblasts was instead less efficacious in potentiating LPS-stimulated IL-10 release and, consequently, in reducing HLA-DR and CD40 expression, suggesting that an impairment of the immune regulation operated by fibroblasts may be involved in the maintenance of chronic pulmonary inflammation.

Abstract
To explore the type 1 and type 2 cytokine profile in cases coinfected with human immunodeficiency virus (HIV) and Leishmania infantum, production of interleukin-4 (IL-4), interleukin-10 (IL-10), interferon-gamma (IFN-gamma), and interleukin-2 receptor (IL-2R) was investigated in mitogen-stimulated and unstimulated peripheral blood mononuclear cell cultures from eight HIV/Leishmania coinfected subjects matched with eight anti-HIV-positive subjects with no evidence of Leishmania coinfection. Levels of IL-4 and IL-2R increased significantly from the baseline levels in the peripheral blood mononuclear cell supernatants of HIV/Leishmania coinfected subjects following stimulation with phytohemoagglutin, whereas the postchallenge concentration of IFN-gamma was significantly increased in the HIV-infected group. The levels of IL-4 and IL-10 were significantly higher in the HIV/Leishmania group throughout evaluation. Post-stimulation IFN-gamma production was significantly higher in the HIV-positive group in comparison with that of the HIV-Leishmania coinfected subjects. These observations support the notion that a Th2 cytokine response is present during a Leishmania infection, even among HIV-coinfected individuals.

Abstract
UNLABELLED This study compared three radionuclide techniques in distinguishing musculoskeletal infection from noninfectious inflammation. METHODS Thirty-five orthopedic patients with suspected musculoskeletal infection were examined using three radionuclide techniques in sequence: triphasic bone scintigraphy, 99mTc radioleukocytes (99mTc-WBC) scintigraphy and 99mTc human immunoglobulin (99mTc-Hig) scintigraphy. Two "early" and "late" acquisitions were performed, at 4-6 hr and 20-24 hr postinjection, respectively. Patients who were diagnosed as suffering from noninflammatory lesions became the controls. We calcu"late"d for all studies one index of inflammation (Infl) as the ratio between counts in the uptake area and counts in an equal area of normal tissue. RESULTS The "early" radiolabeled leukocytes and "late" Hig scintigraphy allowed the greatest ability to distinguish between infections and noninfectious inflammations (p < 0.011 and p < 0.016) with a sensitivity of 96.6% and 96.5% and specificity of 71% and 100%, respectively. Hig and radioleukocytes allowed distinguishing infections from noninflammatory diseases at both examinations. CONCLUSION The "early" radioleukocyte scintigraphy allowed us to separate infections from noninfectious inflammations. In contrast, the same result can be obtained only with the "late" scan in the Hig study, but Hig mapped the spread of the inflammation into soft tissues better. Hig might be an alternative to radioleukocytes because of its simple preparation, similar accuracy and safety.

Abstract
The clinical research was carried on in the department of Oral Surgery of the Maxillo-Facial Surgery Division of Turin University and concerned patients of an average age of 15 years. All the patients underwent the operation for orthodontic reasons. About two years after operation patients were called and underwent a check-up to see the surgical scar and to examine the health of lower second molars that could have been damaged during surgical operations for germectomy. Periodontal probings were effected around all lower second molars, therefore their mobility level an vitality were observed. Nervous alterations were researched and the authors effected a radiographic check-up to look for possible bone-loss after germectomy. According to the results obtained, the authors assert that the health of lower second molars isn't damaged by germectomy of lower third molars. So although not welcome by the young patients, the authors affirm that preventive germectomy of lower third molars compared to correct indications is a justified treatment.

Abstract
The endogenous tachykinins exhibit a range of properties which may be relevant in the pathophysiology of asthma. Their effects on the airways seem to be modulated by a variety of lung peptidases, including neutral endopeptidase (NEP). In order to evaluate the potential role of endogenous NEP activity in modulating tachykinins-induced bronchoconstriction in man in vivo, six atopic asthmatic patients, with a mean FEV1 value of 3.38 +/- 0.76 l, and a histamine PD20 mean value of 0.024 mg, were studied. The influence of inhaled phosphoramidon (a potent NEP inhibitor) was examined against the NKA-induced bronchospasm in a double-blind, placebo-controlled randomized study. Changes in airway calibre were followed as FEV1 and agonists responsiveness expressed as PD20 and PD15 for histamine and NKA respectively. Patients received nebulized phosphoramidon sodium salt (10(-5) M) or a control solution 10 min prior to the bronchoprovocation test with NKA. No significant difference was noticed between any of the study days and after inhaled phosphoramidon on baseline FEV1 values (3.29 +/- 0.90 l) in comparison with the control solution (3.31 +/- 0.79 l). Inhaled NKA produced a dose-dependent fall in FEV1 values in all the subjects studied with a mean PD15 value of 20.91 x 10(-9) mol. Phosphoramidon administered by inhalation elicited a significant (P < 0.01 vs baseline and control solution) potentiation in the airway responsiveness to inhaled NKA, the NKA PD15 value decreasing to 9.45 x 10(-9) mol. The present study confirms that inhaled NKA induces a dose-related bronchoconstriction in asthmatic patients and demonstrates that inhaled phosphoramidon potentiates NKA-induced bronchoconstriction.

Abstract
BACKGROUND Kinins are potent vasoactive oligopeptides that may act as mediators in a variety of inflammatory diseases of the skin by interacting with specific receptors designated B1 and B2. In this study we have investigated the structure-activity relationship of intradermally injected bradykinin, kallidin (lysine-bradykinin), and [desArg9]-bradykinin in atopic (n = 8) and nonatopic (n = 8) subjects. METHODS On two separate occasions, each separated by a week, subjects randomly underwent intradermal challenge with incremental doses (0.5, 5, and 50 nmol) of either the B1-agonist [desArg9]-bradykinin, the B2-agonists bradykinin or kallidin, or vehicle placebo. In a separate randomized double-blind study we have also examined the effect of an orally administered antihistamine, terfenadine, on kinin-induced wheal and flare responses and their repeatability in a group of nine volunteers. The skin responses were monitored objectively by measurement of wheal and flare areas. RESULTS Both bradykinin and kallidin induced a dose-dependent increase in wheal and flare areas in all subjects studied. Although the effects of the two lowest doses (0.5 and 5 nmol) of [desArg9]-bradykinin on skin responses were indistinguishable from those of placebo, this kinin at the highest dose administered (50 nmol) caused a significant increase in wheal and flare areas in all subjects studied. No difference could be identified in the skin responses to kinins between atopic and nonatopic subjects. In addition kinin-induced cutaneous responses were not altered by pretreatment with terfenadine. CONCLUSIONS These in vivo structure activity studies suggest that in human beings the skin responses to kinins may be compatible with the stimulation of B2 receptors, which is unrelated to histamine release from cutaneous mast cells.

Abstract
Sixty-eight severely head injured comatose patients were studied. Bit-colour-mapped SEPs to median nerve stimulation, BAEPs, CT and SPET regional values and ICP were assessed in relation to clinical information in evaluating cerebral function. All these variables were related to a 1-year outcome. Statistical tests confirmed the higher predictive reliability of both neurophysiological and perfusive (SPET) functional parameters compared to CT structural findings. Generally, SEPs appeared to be more reliable in predicting outcome than BAEPs. Modifications of frontal components could occur independently of post-central ones, being closely related to underlying cerebral lesions. The parameter showing the greatest correlation with outcome in the first recording session was the P25 latency, whereas this prognostic role was mainly assumed by the amplitude value of the frontal N30-P45 complex in a second recording session carried out during the third week following head trauma.

Abstract
Pre-treatment with topical capsaicin is known to induce neuropeptide depletion from sensory nerve endings and it is a useful pharmacological tool to evaluate the contribution of these nerves to skin injury and inflammation. To investigate the relative contribution of sensory neural stimulation to the action of bradykinin and histamine, a randomized, double-blind study has been undertaken evaluating the effect of topical capsaicin pre-treatment on the responses to intradermal injections of both agonists in 12 healthy volunteers. Capsaicin pre-treatment caused significant inhibition of the immediate mean flare responses (95% CI) to both bradykinin (from 51.5 [39.7-63.3] mm2 to 16.2 [8.0-24.5] mm2) (P < 0.01) and histamine (from 108.4 [80.4-136.4] mm2 to 52.3 [37.1-67.1] mm2) (P < 0.01). Topical capsaicin elicited a significant inhibition of the weal response induced by histamine, the mean weal area being reduced from 14.8 (12.6-17.0) mm2 to 12.1 (10.1-14.1) mm2 (P < 0.05). In addition, the effect of topical capsaicin was to completely inhibit the bradykinin induced weal response compared to control, the mean weal area (95% CI) being reduced from 13.4 (11.4-15.4) mm2 to 8.2 (5.3-11.0) mm2 (P < 0.01). Our findings show that repeated topical application with capsaicin led to a significant reduction of the skin responses to intradermal injections with both agonists, and particularly with bradykinin. The weal responsiveness to bradykinin may entirely follow neuropeptide release from sensory nerves within the skin and the same applies to the flare response, although this is not completely inhibited by topical application with capsaicin.

Abstract
Although adenosine-induced bronchoconstriction is mainly due to mast cell mediator release, vagal reflexes have also been implicated in this response. We have investigated the effect of a specific muscarinic-receptor antagonist, ipratropium bromide, on methacholine- and adenosine-induced bronchoconstriction in a randomized, placebo-controlled, double-blind study of 12 asthmatic subjects. Airway response was evaluated as forced expiratory volume in one second (FEV1). Inhaled ipratropium bromide (40 micrograms), administered 20 min prior to bronchoprovocation, increased the provocation dose of inhaled methacholine and adenosine required to reduce FEV1 by 20% from baseline (PD20) from 0.11 to 0.79 mg (p less than 0.01) and from 0.57 to 1.27 mg (p less than 0.01), respectively. The mean baseline FEV1 values after administration of ipratropium bromide were significantly higher than after placebo administration (p less than 0.05). However, there was no correlation between the degree of bronchodilatation and dose-ratios for methacholine and adenosine. The findings of the present study implicate vagal reflexes in the bronchospastic response induced by inhaled adenosine in asthma.

Abstract
Neurokinin A (NKA) has been shown to exert a potent contractile action on bronchial smooth muscles both in vitro and in vivo. Although this effect seems to be due either to a direct action of this peptide on specific muscular receptors or to an indirect effect on mast cells and/or nerves, its mechanism of action in bronchial asthma is still unknown. In the present study we have investigated the airway response to inhaled NKA in 10 asthmatic subjects and the activity of the novel pyranoquinoline dicarboxylic acid drug, nedocromil sodium, on this response. Ten asthmatic patients with stable asthma took part in the study consisting of four separate visits. On the first two occasions we derived histamine and NKA PD15 values in absence of any drug treatment. On the following two visits the inhalation challenge with NKA was performed after administration of either nedocromil sodium or matched placebo administered as pressurized aerosols via metered dose inhalers in a randomized double-blind order. Inhaled NKA produced a dose-related fall in FEV1 in all the subjects studied. Inhaled nedocromil sodium had a significant effect on the FEV1 response to NKA inhalation, the geometric mean PD15 value increasing from 16.6 to 32.2 x 10(-9) mol. We conclude that nedocromil sodium attenuates subsequent responsiveness to inhaled NKA in asthmatic subjects.
