RESUMO
BACKGROUND: The coronavirus disease 2019 (COVID-19), an acute respiratory disease caused by a novel coronavirus (SARS-CoV-2), is emerging as a worldwide public health emergency. Several scientific contributions reported the potential relevance of human leukocyte antigen (HLA) polymorphism and susceptibility to viruses, such as SARS-CoV. In our study, we examined a population of coeliac subjects presenting the HLA haplotype DQ2 and/or DQ8. Our aim was to evaluate whether HLA DQ2 and/or DQ8 haplotype play a role in SARS-CoV-2-infection. The aim was also to evaluate the difficulty in following the gluten-free diet due to all the adversities produced by the pandemic, such as the food supply disruption, and the difficulties in managing the clinical follow-up. METHODS: 191 consecutive coeliac patients completed a questionnaire on their current clinical status, psychological effects, and management of the gluten-free diet experienced during the COVID-19 pandemic and questions regarding possible SARS-CoV-2 infection. RESULTS: Out of the 191 patients who participated in the study, 42 were full-blown coeliac and 149 were in remission. From the answers provided, 84.8% of patients declared that they no longer consider themselves vulnerable to COVID-19 as they suffer from coeliac disease; 94.2% of patients did not encounter any difficulties in managing the gluten-free diet or in acquiring specific foods and 64.9% of patients in our study underwent diagnostic testing for SARS-CoV-2. Out of this number, 31.5% did so due to contacts with subjects affected by COVID-19, 26.6% for work related reasons, 11.3% due to flu-like symptoms and 30.6% for other reasons. Only 5.8% of the enrolled patients received a diagnosis of COVID-19. Out of all the patients in our population who were diagnosed with COVID-19, 94.8% developed no symptoms and none of them needed hospitalization or intensive care. CONCLUSION: The hypothesis that the HLADQ2 and/or DQ8 haplotype plays a protective role against SARS-CoV-2 infection, as against other viral infections, is intriguingly suggestive.KEY MESSAGESCOVID-19 as a public health emergency;SARS-CoV-2 and possible complications in coeliac disease;Role of HLA DQ2 and/or DQ8 in SARS-CoV-2 infection.

The interest in the development of nanoscale plasmonic technologies has dramatically increased in recent years. The photonic properties of plasmonic nanopatterns can be controlled and tuned via their size, shape, or the arrangement of their constituents. In this work, we propose a 2D hybrid metallic polymeric nanostructure based on the octupolar framework with enhanced sensing property. We analyze its plasmonic features both numerically and experimentally, demonstrating the higher values of their relevant figures of merit: we estimated a surface-enhanced Raman spectroscopy (SERS) enhancement factor of 9 × 107 and a SPR bulk sensitivity of 430 nm/RIU. In addition, our nanostructure exhibits a dual resonance in the visible and near-infrared region, enabling our system toward multispectral plasmonic analysis. Finally, we illustrate our design engineering strategy as enabled by electron beam lithography by the outstanding performance of a SERS-based biosensor that targets the Shiga toxin 2a, a clinically relevant bacterial toxin. To the best of our knowledge, this is the first time that a SERS fingerprint of this toxin has been evidenced.

BACKGROUND: The outbreak of coronavirus disease-2019 (COVID-19) is a public health crisis of global proportion. In psoriatic patients treated with biologic agents, evidence is not yet available on susceptibility to infection with the novel SARS-CoV-2 coronavirus, and data about the perception of COVID-19 and its impact on these patients are lacking. AIMS: The aim of this observational, spontaneous study was the evaluation of the impact of anti COVID-19 measures in "fragile population" such as patients with a chronic inflammatory disease. Thus, we evaluated the impact of perceived risk on quality of life of patients with moderate to severe psoriasis, in our outpatient clinic, and how their perceptions changed before and after the adoption of Covid-19 emergency measures following the Italian Ministerial Decree in March 9, 2020. METHODS: Using a series of questions, our study surveyed adult patients with moderate to severe psoriasis receiving treatment with biologic agents (n = 591), before and after the adoption of COVID-19 emergency measures. RESULTS: Most patients (97%) had been sufficiently informed by healthcare staff about COVID-19 spread. A significant change was observed in social activity reduction before and after the adoption of the measures (18% vs. 90% of patients; P < 0.0001). Similarly, patients were more likely to suspend ongoing therapy after the measures were adopted than before (87% vs. 34% of patients; P < 0.0001). Following the measures, older patients were significantly more inclined to suspend therapy and reduce social activities than younger patients. CONCLUSIONS: Government COVID-19 emergency measures further curtailed already reduced social activities in psoriatic patients, and led to a greater inclination to suspend biologic therapy, more so in older patients, despite there being no evidence to support this suspension. These vulnerable patients may need support from clinicians in order to maintain treatment adherence.

Evidences of an association between air pollution and Covid-19 infections are mixed and inconclusive. We conducted an ecological analysis at regional scale of long-term exposure to air-borne particle matter and spread of Covid-19 cases during the first wave of epidemics. Global air pollution and climate data were calculated from satellite earth observation data assimilated into numerical models at 10 km resolution. Main outcome was defined as the cumulative number of cases of Covid-19 in the 14 days following the date when > 10 cumulative cases were reported. Negative binomial mixed effect models were applied to estimate the associations between the outcome and long-term exposure to air pollution at the regional level (PM10, PM2.5), after adjusting for relevant regional and country level covariates and spatial correlation. In total we collected 237,749 Covid-19 cases from 730 regions, 63 countries and 5 continents at May 30, 2020. A 10 µg/m3 increase of pollution level was associated with 8.1% (95% CI 5.4%, 10.5%) and 11.5% (95% CI 7.8%, 14.9%) increases in the number of cases in a 14 days window, for PM2.5 and PM10 respectively. We found an association between Covid-19 cases and air pollution suggestive of a possible causal link among particulate matter levels and incidence of COVID-19.

The widespread diffusion of low-cost but high-performance hardware is enhancing the realization of scientific equipment with features at the research laboratory level. In this paper, we demonstrate hardware implementation of a surface plasmon resonance compact device with high accuracy and measurement times appropriate for many applications. Image acquisition is realized by a Raspberry Pi single board computer with a camera module, and a Python code is used to process data. A flexible optical setup can work in two different configurations, namely, the inspection mode and angle resolved measurement mode. The inspection mode is used to precisely locate the light-emitting diode interrogation beam on the sample, avoiding uneven or faulty regions. The measurement mode allows us to monitor in real time the position of the minimum reflectivity with subpixel resolution. Performance tests show a resolution in the bulk refractive index of 4.9 × 10-6 refractive index units for 10 s acquisition time.
RESUMO
PURPOSE: The aim of the present study is to assess impairment of spermatogenesis induced by varicocele in, to our knowledge, the largest single-centre caseload available to date. MATERIALS AND METHODS: We conducted a retrospective study on 4230 consecutive patients attending our Department for andrological outpatient assessment and preconception check-ups between 2011 and 2014. A total of 2113 patients had varicocele (Group V), while the remaining 2117 were selected as the control group (Group C). All patients were divided into age classes (<17, 18-28, 29-39 and ≥40 years), and Group V patients were classified as "low" (I-II) or "high" (III-IV) grade. RESULTS: Varicocele patients had a higher mean height than controls, as well as lower BMI. There was also a statistically significant reduction in the concentration/mL and the total sperm number in Group V against Group C. When stratified by age, values for all semen parameters were significantly worse in the older than in the younger age classes in both Group V and Group C, except for concentration/mL and total sperm number in the 29-39 and ≥40 age classes in both groups. A multivariable logistic regression analysis showed that factors independently predicting the presence of varicocele were older age, higher BMI and smoking for more than 10 years. CONCLUSIONS: Varicocele patients show worse semen parameters compared to controls, although their values were still within WHO reference limits. Semen quality is further worsened by increased age, grade and chronic smoking.

UNLABELLED: Bisphosphonate treatment is used to prevent bone fractures. A controversial association of bisphosphonate use and risk of atrial fibrillation has been reported. In our study, current alendronate users were associated with a higher risk of atrial fibrillation as compared with those who had stopped bisphosphonate (BP) therapy for more than 1 year. INTRODUCTION: Bisphosphonates are widely used to prevent bone fractures. Controversial findings regarding the association between bisphosphonate use and the risk of atrial fibrillation (AF) have been reported. The aim of this study was to evaluate the risk of AF in association with BP exposure. METHODS: We performed a nested case-control study using the databases of drug-dispensing and hospital discharge diagnoses from five Italian regions. The data cover a period ranging from July 1, 2003 to December 31, 2006. The study population comprised new users of bisphosphonates aged 55 years and older. Patients were followed from the first BP prescription until an occurrence of an AF diagnosis (index date, i.e., ID), cancer, death, or the end of the study period, whichever came first. For the risk estimation, any AF case was matched by age and sex to up to 10 controls from the same source population. A conditional logistic regression was performed to obtain the odds ratio with 95% confidence intervals (CI). The BP exposure was classified into current (<90 days prior to ID), recent (91-180), past (181-364), and distant past (≥365) use, with the latter category being used as a reference point. A subgroup analysis by individual BP was then carried out. RESULTS: In comparison with distant past users of BP, current users of BP showed an almost twofold increased risk of AF: odds ratio (OR) = 1.78 and 95% CI = 1.46-2.16. Specifically, alendronate users were mostly associated with AF as compared with distant past use of BP (OR, 1.97; 95% CI, 1.59-2.43). CONCLUSION: In our nested case-control study, current users of BP are associated with a higher risk of atrial fibrillation as compared with those who had stopped BP treatment for more than 1 year.

OBJECTIVES: To verify the prevalence of chronic cerebrospinal venous insufficiency in patients affected by different clinical forms of multiple sclerosis and in healthy subjects using the Zamboni ultrasound protocol combined with M-mode ultrasound examination. MATERIALS AND METHODS: We enrolled 112 patients with multiple sclerosis and 67 healthy subjects from 20 to 67 years of age. All the patients underwent Duplex and color-Doppler sonography of the neck vessels, transcranial colour duplex sonography, M-mode study of the valve system and of venous abnormalities. Subjects were positive for chronic cerebrospinal venous insufficiency when at least two of five hemodynamic criteria of the Zamboni protocol were fulfilled. Chronic cerebrospinal venous insufficiency condition was further analyzed by a multivariate analysis including age, sex, disease duration, subtypes of multiple sclerosis and expanded disability status scale score as independent variables. RESULTS: No healthy subjects was positive for chronic cerebrospinal venous insufficiency, while in the sample of patients affected by multiple sclerosis the diagnosis was made in 59.8% of cases (p < 0.0001). The first criterion was the most frequent in patients affected by multiple sclerosis and chronic cerebrospinal venous insufficiency (respectively 54.4% and 76.1%, p < 0.001). The second, third and fourth criteria were never present in healthy subjects but were detected in patients with multiple sclerosis. The positivity of the second criterion was associated with diagnosis of chronic cerebrospinal venous insufficiency in 100% of cases. The third criterion had a prevalence of 52.2% in the subgroup of chronic cerebrospinal venous insufficiency patients. It was positive in 36 multiple sclerosis patients and was associated with chronic cerebrospinal venous insufficiency diagnosis in all cases except one. The multivariate analysis showed that age, disease duration, sex, subtypes of multiple sclerosis and expanded disability status scale score were not considered predictors of this haemodynamic condition. CONCLUSION: Chronic cerebrospinal venous insufficiency is a haemodynamic condition strongly associated with multiple sclerosis and is not found in normal controls. The addition of M-mode ultrasound to the diagnostic protocol allows improved observation of venous valve abnormalities.

The gallstone ileus is a rare complication of cholelithiasis and it represents the 1-4% of small intestinal mechanical obstruction. Gallstone is generally wedged in the terminal ileum, even if unusual locations have been described. The literature reports a very high morbidity and mortality, often because misdiagnosis or delayed diagnosis. There is no unique opinion in literature about the choice between one-stage and two-stage surgery. We report a clinical case that summarizes the diagnostic and therapeutic difficulties of gallstone ileus.

SUMMARY: There is evidence that the use oral bisphosphonates can lead to osteronecrosis of the jaws (ONJ). Although the occurrence of ONJ appears rare among oral bisphosphonates (BPs) users, it is important to know that it exists and can be opportunely minimized. INTRODUCTION: The purpose of this study is to evaluate the association between BPs prescribed for the secondary prevention of osteoporotic fractures and the occurrence of ONJ. METHODS: An Italian record linkage claims database with a target population of around 18 million individuals (6 million over 55 years of age) constituted the data source. We conducted a nested case-control study within a cohort of individuals aged 55+ years old, who were discharged from hospitals with a primary diagnosis of incident osteoporotic fracture. The date related to the discharge diagnosis of ONJ was the index date. Conditional logistic regression for matched data was fitted to estimate the odds ratio (OR) along with 95 % confidence intervals (95 % CI) for the likely association between use of BPs and the risk of ONJ. RESULTS: Any one of the 61 ascertained cases of ONJ (incidence rate, 36.6 per 100,000 person-years) was matched to 20 controls for a total of 1120 controls. When the exposure to BPs was modeled according to recency (i.e., exposure time window prior to the index date) of use, the adjusted OR (95 % CI) for current users was 2.8 (1.3-5.9) against never users. The cumulative use of BPs has shown to increase the incidence of ONJ among patients with primary osteoporotic fractures, although not statistically significant risk has been observed. CONCLUSIONS: Although the risk of BP-related ONJ appears low in non-oncological indications, it is important to be aware that it exists and to know how it may be predicted and possibly minimized.

The human hepcidin-25 hormone has a key role in iron regulation in blood. The clinical relevance of this hepatic ~2.8 kDa cysteine-rich peptide is rapidly increasing, since altered levels can be associated with inflammatory events and iron dysfunctions, such as hereditary hemochromatosis and iron overload. Moreover, hepcidin has also attracted the anti-doping field for its possible role as indirect marker of erythropoietin blood doping. Methods currently reported are based on immunoassays (ELISA and RIA), or various types of mass spectroscopy (MS)-based protocols, semi-quantitative or quantitative. Despite the great effort in optimizing robust and simple assays measuring hepcidin in real matrices, at present this challenge remains still an open issue. To explore the possibility to face hepcidin detection through the development of affinity-based biosensors, we set up a comparative study by surface plasmon resonance (SPR) technology. An immuno-based, on anti-hepcidin-25 IgG, and a biomimetic-based, on a synthetic peptide corresponding to the hepcidin-binding site on ferroportin (HBD), biosensors were developed. Here we report behaviors and analytical performances of the two systems, discussing limits and potentialities.

The purpose of the present study was to evaluate breast mammographic features, particularly mammographic density in a selected population of infertile women and to assess if these women should be considered at higher risk for breast cancer. The prevalence of female infertility in Western countries is approximately 10-15% and since causes affecting the female are involved in 35-40%, concerns have developed about the future health of these women, specifically whether infertility could represent a risk factor for future cancer development. Moreover, infertility is now often treated with medication and procedures that could modify the hormonal environment and be cofactors in the cellular changes towards cancer development. Mammographic breast density is a useful marker for breast cancer risk and breast density is considered one of the strongest risk factors for breast cancer. Breast density is associated with known breast cancer risk factors such as reproductive and menstrual factors including serum estrogen and progesterone concentrations. In Italy the National Federation for Breast Cancer (FONCAM) guidelines suggest the usefulness of mammography from 35 years of age for women who undergo infertility hormone therapy (FONCAM Guidelines, 2005). According to this recommendation 294 women aged > or = 35, with primary infertility, sent to our breast service before joining an IVF program were recruited and then underwent clinical examination and X-ray mammography. Women were divided into two groups: dense breast (DB) and non-dense breast (NDB). Univariate analysis was employed to evaluate if there was an association between mammographic density and other risk factors. Evaluation of mammographic features showed the presence of BI-RADs C and D in the sample of 200 (68%) patients with DB and in 94 (32%) patients with NDB BI-RADS A and B. Univariate analysis showed that there were no statistically significant differences between the groups BD and NDB as regards age at mammography, age at menarche, BMI and family history for breast cancer, while ovulatory etiology of infertility was found to be associated with high mammographic density (p < 0.05). In conclusion, bearing in mind that 68% of our study sample had high breast density, we can assume that patients with primary infertility might represent a group at high risk for breast cancer, particularly if infertility is due to an ovulatory factor. We suggest breast screening from the age of 35 in infertile patients who undergo treatment with fertility drugs in accordance with FONCAM recommendations. This might allow the identification of higher risk patients who need more closely monitored breast examinations.

AIM: The purpose of this retrospective case study is to describe the body mass index in a group of children, from 3 to 6 years old with ECC and a similar group of caries-free children. MATERIALS AND METHODS: This case-control analysis involves two groups of children: the first was of 244 healthy children, 3 to 6 year-old and caries-free; the second was of 586 otherwise healthy children, same age, with Early Childhood Caries divided into three subgroups according the AAPD definition. Demographics, dmft, number teeth with pulpal involvement, BMI percentile, weight at birth, weight and height of both parents were measured during the clinical evaluation. Statistical analyses were performed using standard statistical software (SPSS Version 13). BMI distribution of the subjects with caries was graphically compared with the use of confidence intervals to a similar caries-free sample. RESULTS: Results are expressed as mean ± SD and frequencies (percentages), depending on the data type. The distribution of BMI percentiles of the ECC group was: underweight = 10%; normal weight = 55.90%; at risk of overweight = 22.22 %; overweight = 11.11%. Significantly, more children in the case group were underweight than in the control group (10% vs. 4.94%). CONCLUSION: The ECC population does not have a typical weight distribution, and the underweight finding in a significant number of Severe ECC (S-ECC) children may be due to the chewing alteration related to the dental pain due to caries and to missing teeth after hard tissues breakdown.

OBJECTIVE: The pouch-related fistulas range in literature from 2% to 16% and they can be cause of failure of the intervention of restorative proctocolectomy. Aim of this study was to examine factors associated with theirs development and to identify theirs possible etiology and pathogenesis. MATERIALS AND METHODS: Retrospective study focusing on 100 consecutive patients who underwent restorative proctocolectomy with pouch-anal anastomosis (IPAA). Patients with fistula and patients without fistula have been identified and the fistula type, the time from surgery and the site relative to IPAA have been recorded. Patients' demographics, co-morbidity or related medical history, clinical indication for treatment, surgical method, histological diagnosis, length of follow-up, early and late postoperative complications have been reviewed, and data collected have been compared among the two groups through univariate analysis. RESULTS: The overall incidence of fistulas was of 10% (10 cases); 8 cases had pouch-vaginal fistulas, involving the distal tract of the vagina, and associated with pouch-perineal fistulas in 2 cases; 1 case had pouch-vulval fistula; 1 case had a complex pouch-perineal fistula. Three fistulas were precocious, all associated with an IPAA leak; 2 of these cases also had pelvic sepsis while the third had delayed diagnosis of Crohns disease. Seven fistulas had a late development. Four fistulas occurred at the level of the IPAA; 5 fistulas were located below the IPAA, and 1 fistula originated above and below the IPAA. When the two groups of patients were compared we found that there was an higher percentage of perineal or anal disease (40.0% vs 2.2%; p <0.001), of extraintestinal manifestations of inflammatory bowel disease (IBD) (40.0% vs 3.3%, p <0.001), and of leak of the IPAA (40.0% vs 11.1%; p <0.05) in the group with fistula vs the group without fistula. CONCLUSIONS: A direct link with the leak of the IPAA appears in all the early fistulas, while the cryptoglandular infection was suggested as a possible cause of the late fistulas located below the IPAA; the association with the extraintestinal manifestations of IBD could show a correlation between the fistulas and an higher specific activity of the underlying chronic inflammatory disease.

The aim of this study, conducted in the Province of Latina, was to verify knowledge, attitudes, and lifestyles in relation to oral health in a sample of pregnant women, assessing their subjective perception of oral health, and highlight prenatal dental prevention need specialist in the area and provide adequate information on the importance of good oral hygiene in order to achieve a better health level both of the mother and the child. The study was conducted on a sample of pregnant women between the 26th and 39th gestational week, in the period from June to October 2009, during the childbirth training courses in the Province of Latina. Each patient was administered a questionnaire for the assessment of oral habits during pregnancy and for the definition of specific knowledge on and perception of themselves and their own oral condition. The survey shows that more than one third of the sample reported visiting a dentist only in case of pain, over half (56.9%) did not undergo any dental visit during the gestational period, only 24 subjects (33.3%) having applied to a dental hygienist for professional oral hygiene and that only 7 out of 72 women had been prescribed a dental checkup by a gynecologist. The study showed that knowledge about dental problems that may arise during pregnancy is insufficient to guarantee a good threshold to oral health care for the mother hence the need to promote information programs, oral health and pregnancy prevention and training in the territory mainly directed to health-care specialists (gynecologists and obstetricians) and to pregnant women.

AIM: The aim of this paper was to evaluate the feasibility, morbidity, and reproductive performance of fertile women undergoing minilaparotomic myomectomy for large uterine myomas. METHODS: Ninety-nine consecutive women with symptomatic myomas underwent myomectomy through a skin incision ≤8 cm. Operative, postoperative and reproductive data were prospectively collected. RESULTS: Median (range) age and Body Mass Index (BMI) were 37 years (23-44) and 23 (18-43), respectively. Median (range) myoma diameter was 7 cm (4-20), and the median number of myomas removed was 1 (range 1-31). Myomas were intramural in 76 (76%) cases. Median incision length was 7 cm (range 4-13) and median duration of surgery was 70 min (range 40-180). Operative time and length of skin incision were not correlated with the progressive number of interventions. An incision larger than 8 cm was necessary in 7 (7%) patients and the length of incision was significantly correlated with the diameter of the largest myoma (P<0.01). The feasibility of minilaparotomy was significantly reduced when the diameter of the largest myoma was >12 cm (P<0.05). Operative time was significantly longer in patients having >1 myoma (P<0.05). Three (3%) patients underwent blood transfusion. Median (range) postoperative stay was 2 days (range 2-12). Fever occurred in 8 (8%) patients, and wound complications in 5 (5%). CONCLUSION: Myomectomy by minilaparotomy is a feasible procedure in more than 90% of unselected patients with large symptomatic myomas. Feasibility is questionable when the myoma is >12 cm. This technique is a mini-invasive option to treat patients with large and multiple myomas.

Decreased reserves in multiple organ systems identify frailty syndrome in the elderly. However, its clinical diagnostic approach may be hard, particularly in patients with chronic diseases. The purpose of the study was to delineate the role of disability in the frailty syndrome in a group of hospitalized elderly people. A total of 150 consecutive patients (62 males/88 females), aged between 64 and 97 years and 1-2 days before hospital discharge, were submitted to several geriatric scales designed to assess disability and/or morbidity. All the geriatric scales used showed an elevated percentage of abnormal values both in females and in males. Nevertheless, the activities of daily living (ADL), instrumental activities of daily living (IADL), Tinetti balance index (TBI), Barthel index (BI) scores showed significantly better values in men than in women (p=0.007, =0.02, =0.02 and =0.01, respectively). This preliminary cross-sectional study, underlines the fact that all geriatric tests employed have shown pathological scores, but those of the ADL, IADL, TBI and BI scores exploring disability were significantly better in males than in females. The mismatch between functional and morbidity tests seems to support the hypothesis that a disability state may be independent from morbidity.

OBJECTIVE: There is increasing evidence suggesting that neuroinflammation and microglia activation may play important roles in the pathway leading to neuronal cell death in Parkinson's disease (PD). Chronic activation of microglia may cause neuronal damage through the release of potentially cytotoxic molecules, such as pro-inflammatory cytokines. Different functional promoter polymorphisms within genes coding pro- or anti-inflammatory cytokines involved in the immune reactions in the brain might influence the risk of developing PD or the age of disease onset. AIM: To investigate the interleukin (IL)-1ß-511, tumor necrosis factor alpha (TNF-α)-308, and interleukin (IL)-10-1082 gene polymorphisms as susceptibility factors for PD. METHODS: We analyzed genotype and allele distributions of these polymorphisms in 146 Italian patients with PD and 156 healthy controls. RESULTS: None of the polymorphisms we investigated was found to be associated with PD or with age of disease onset. No significant differences between patients with PD and controls were found as regards the concomitant presence of variant alleles in the three polymorphisms studied. We found that only the combined genotype TNF-α-308GG/IL-1ß-511T+ is associated with a decreased risk of PD. CONCLUSION: Our results indicate that the cytokine gene polymorphisms we investigated are not related to the development of PD in the Italian population; further studies are warranted to clarify the role of the TNF-α-308GG/IL-1ß-511T+ combined genotype.

BACKGROUND AND AIM: Multi Detector Computed Tomography (MDCT) is widely used in the preoperative staging of gastric cancer. MRI has an emerging role in the evaluation of intestinal diseases, although its role in the staging of gastric cancers is still to be defined. The aim of our study was to compare the diagnostic accuracy of MDCT and Magnetic Resonance Imaging (MRI) in the diagnosis and preoperative staging of gastric cancer, in comparison with histopathology. MATERIALS AND METHODS: Twenty-five patients with an endoscopic diagnosis of gastric cancer underwent preoperative contrast-enhanced MDCT and MRI, blind to the results of endoscopy. MDCT (64 slices) was performed after oral administration of 800-1000 mL of tap water and scopolamine injection five minutes before the examination. The scan was performed in the axial plane before and after intravenous injection of iodinate contrast medium. Multiplanar reconstruction images were obtained on coronal and sagittal planes. MRI was performed with a 1.5 T Magnet, using the same patient's preparation, by acquiring T2-weighted HASTE sequences, with or without fat saturation (FS), True FISP (True fast imaging with steady state precession) and T1-weighted VIBE (Volumetric interpolated breath-hold examination) sequences, with and without FS, before and after contrast agent (gadolinium) i.v. injection. Gold standards (GS) were surgical and histopathological findings. Two groups of radiologists, blind each other, analyzed MRI images and MDCT findings, and related to GS results. RESULTS: Detection rate of gastric lesions and T staging for gastric cancer were similar for MRI and MDCT (92%); MRI imaging was superior than MDCT in staging the T parameter (60% versus 48%); the accuracy of MRI imaging and 64-MDCT did not differ significantly in the evaluation of N staging (68% versus 72%). CONCLUSIONS: Both MRI and MDCT were comparable in staging gastric cancer. MRI was more accurate in evaluation of T stage than MDCT, although both imaging modalities showed low accuracy in detection of early gastric cancer and in differentiation of T2 from T3 stage.

AIM: Sealing of pits and fissures is one of the most effective techniques in caries prevention: however incomplete removal of plaque debris, can cause lack of retention of the sealant. MATERIALS AND METHODS: Sixty first permanent molars were sealed for this study. The teeth were divided into four groups. All teeth were isolated with a dental dam before cleaning and coronal polishing was performed with synthetic bristles or air polishing. Disclosing solution was used to reveal plaque. Three different operators performed cleanings and sealing. RESULTS: The results show that the plaque indicator was necessary to ensure complete cleansing of pit and fissures. PROPHYflex3 was the easiest and most effective device for removing plaque and debris. Synthetic bristles failed to thoroughly cleanse the surface in most attempts. CONCLUSION: Results suggest that pits and fissures should be cleaned with a plaque indicator and air polishers before placing a sealing material to ensure complete removal of plaque from the tooth.
