In recent years, increasing attention has been paid to understanding the causes of infertility, which is being recognized as a growing health problem affecting large numbers of couples worldwide. Male infertility is a contributing factor in approximately 30-40% of cases, and one of its etiological causes is sexually transmitted infections (STIs). Among sexually transmitted pathogens, human papillomavirus (HPV) can contribute in various ways to the failure of spontaneous and assisted reproduction, acting in the different phases of conception, especially in the early ones. In particular, HPV infection can affect sperm DNA integrity, sperm motility, count, viability, and morphology and can induce the production of anti-sperm antibodies (ASAs). In this narrative review, we aimed to provide an overview of existing research on the potential adverse effects of HPV infection on male reproductive health. Furthermore, we analyzed how limiting the spread of the infection, particularly with gender-neutral vaccination, could be a possible therapeutic tool to counteract male and female fertility problems.

Although the anti-COVID-19 vaccination has proved to be an effective preventive tool, "breakthrough infections" have been documented in patients with complete primary vaccination courses. Most of the SARS-CoV-2 neutralizing antibodies produced after SARS-CoV-2 infection target the spike protein receptor-binding domain which has an important role in facilitating viral entry and the infection of the host cells. SARS-CoV-2 has demonstrated the ability to evolve by accumulating mutations in the spike protein to escape the humoral response of a host. The aim of this study was to compare the titers of neutralizing antibodies (NtAbs) against the variants of SARS-CoV-2 by analyzing the sera of recovered and vaccinated healthcare workers (HCWs). A total of 293 HCWs were enrolled and divided into three cohorts as follows: 91 who had recovered from SARS-CoV-2 infection (nVP); 102 that were vaccinated and became positive after the primary cycle (VP); and 100 that were vaccinated with complete primary cycles and concluded the follow-up period without becoming positive (VN). Higher neutralization titers were observed in the vaccinated subjects' arms compared to the nVP subjects' arms. Differences in neutralization titers between arms for single variants were statistically highly significant ( p < 0.001), except for the differences between titers against the Alpha variant in the nVP and in VP groups, which were also statistically significant ( p < 0.05). Within the nVP group, the number of subjects with an absence of neutralizing antibodies was high. The presence of higher titers in patients with a complete primary cycle compared to patients who had recovered from infection suggested the better efficacy of artificial immunization compared to natural immunization, and this further encourages the promotion of vaccination even in subjects with previous infections., Competing Interests: The authors declare no conflict of interest.

Knowledge of human papillomavirus transmission from the genital tract to the oral mucosa remains unsatisfactory, with poor and often inconsistent literature results. The increase in HPV-associated oral malignancies prompts further analysis of the simultaneous detection of the virus in the two anatomical areas and on the identification of genotypes to be included in future vaccines. Therefore, in this retrospective study, we evaluated orogenital HPV concurrence, hrHPV, lrHPV and type-concordance in 337 samples, as well as the prevalence of the most common genotypes not included in HPV vaccines. Concurrence was found in 12.5% (31/248) of cases, hr-concordance in 61.3% (19/31) and lr-concordance in 12.9% (4/31). Finally, type-concordance was found in 32.3% (10/31) of concurrent infections. Regarding the identification of non-vaccine genotypes, the significantly prevalent genotypes in the anogenital area were HPV66 (12.6%, p < 0.0001), HPV53 (11.1%, p < 0.0001), HPV51 (8.7%, p < 0.0001), HPV42 (8.2%, p < 0.0001) and HPV68 (5.6%, p = 0.0034) in women and HPV66 (14.6%, p = 0.0058), HPV42 (12.2%, p = 0.0428), HPV51 (12.2%, p = 0.0428), HPV53 (12.2%, p = 0.0428), HPV70 (12.2%, p = 0.0428) and HPV73 (12.2%, p = 0.0428) in men. Considering the results of our study, we recommend including the high-risk genotypes HPV51, HPV68, HPV53 and HPV66 in future HPV vaccine formulations.

Introduction. Serological screening and seroprevalence data for TORCH infections represent a key instrument to estimate immunity and vaccination levels and exposure rates to prevent and treat TORCH congenital infections. Hypothesis. Serology allows us to identify women susceptible to primary infection. Aim. Assess the prevalence of women at risk of primary infections by TORCH pathogens in Palermo, Sicily, Italy, in the decade 2012-2022. Methodology. A retrospective study was performed to evaluate the serological status (IgG and/or IgM) of 2359 women of childbearing age (WCBA), ranging from 16 to 46 years, attending the AOUP 'P. Giaccone' University Hospital of Palermo. Results. The results showed an overall prevalence of anti-TORCH IgG of 90.5 % for herpesvirus (HSV), 81.2 % for rubella virus (RV), 72.1 % for cytomegalovirus (CMV), 20.9 % for Toxoplasma gondii (TOX) and 4.8 % for Treponema pallidum (TP). IgM positivity was 16.9 % for HSV2, 10.3 % for TOX, 4 % for CMV and, 2 % for RV. A recent/active infection by TP was confirmed in 28.3 % of the seropositive women. Our results indicate that only a small percentage of WCBA were subjected to a comprehensive TORCH serological screening, while most WCBA were only tested for a single pathogen. In addition, no significant differences were found in terms of the overall TORCH IgG seroprevalence among different age groups ( P >0.05). Conclusion. Identifying WCBA at risk of exposure during pregnancy allows us to prevent and reduce possible congenital infections, providing detailed guidelines and instructions. The results of this study showed that in Italy the risk of acquiring a primary infection by a TORCH agent is still high, therefore effective prevention strategies, including serological screening, should be implemented.

Background: The abuse of antibiotics during the SARS-CoV-2 pandemic might have disrupted efforts to curb the further development and spread of the antimicrobial resistance of Staphylococcus aureus infection and Staphylococcus spp. coagulase-negative (CoNS) agents of nosocomial bloodstream infections (NBSIs). The purpose of our work was to study the resistance patterns of Staphylococcus aureus and CoNS through the analysis of blood cultures in hospitalized SARS-CoV-2-positive and SARS-CoV-2-negative patients (pts.)., Materials and Methods: During the period January 2018-June 2021, a retrospective case-control study was performed on blood cultures positive for Staphylococcus spp. detected in 177 adult pts. (≥18 years old) hospitalized for >48 hours at Sant'Elia Hospital, Caltanissetta., Results: Staphylococcus aureus was isolated in 33.9% of blood culture samples, and among CoNS, the most frequent strains were Staphylococcus capitis (18.6%) and Staphylococcus hominis (18.1%). Patients aged ≥ 65 years, with a greater number of males, comprised the SARS-CoV-2-negative pts. (71.8% vs. 52.2%, p = 0.0154). Among the SARS-CoV-2-positive patients, the significant resistance of Staphylococcus aureus was only observed for erythromycin (57.1%). The oxacillin resistance of Staphylococcus capitis was higher in SARS-CoV-2-positive than in negative pts. (90% and 78.3%, respectively). Comparing the two groups, we found an increase in resistance in SARS-CoV-2-negative patients for the following antibiotics: gentamicin for Staphylococcus aureus ( p = 0.007), clindamycin and erythromycin ( p = 0.012) for Staphylococcus hominis and oxacillin and rifampicin for Staphylococcus haemoliticus ( p = 0.012)., Conclusions: Our study confirms the relevance of oxacillin-resistant Staphylococcus aureus in being responsible for bloodstream infection and draws attention to highly oxacillin-resistant CoNS such as Staphylococcus capitis . The presence of resistant strains of CoNS in hospitals can be worrying, as it limits treatment options and worsens outcomes. The Infection Control Committee (ICC) recommends new treatment strategies to decrease colonization and infections. As part of the implementation of a bloodstream infection prevention program, the authors encourage the introduction of a report on the antimicrobial resistance of hospital bacteremia due to CoNS.

Genetic predisposition, environmental factors, and infectious agents interact in the development of gastric diseases. Helicobacter pylori (Hp) and Epstein-Barr virus (EBV) infection has recently been shown to be correlated with these diseases. A cross-sectional study was performed on 100 hospitalized Italian patients with and without gastric diseases. The patients were stratified into four groups. Significant methylation status differences among CDH1, DAPK, COX2, hMLH1 and CDKN2A were observed for coinfected (Hp-EBV group) patients; particularly, a significant presence of COX2 ( p = 0.0179) was observed. For microsatellite instability, minor stability was described in the Hp-HBV group (69.23%, p = 0.0456). Finally, for p53 mutation in the EBV group, exon 6 was, significantly, most frequent in comparison to others ( p = 0.0124), and in the Hp-EBV group exon 8 was, significantly, most frequent in comparison to others ( p < 0.0001). A significant positive relationship was found between patients with infection (Hp, EBV or both) and p53 mutation (rho = 0.383, p = 0.0001), methylation status (rho = 0.432, p < 0.0001) and microsatellite instability (rho = 0.285, p = 0.004). Finally, we observed among infection and methylation status, microsatellite instability, and p53 mutation a significant positive relationship only between infection and methylation status (OR = 3.78, p = 0.0075) and infection and p53 mutation (OR = 6.21, p = 0.0082). According to our analysis, gastric disease in the Sicilian population has different pathways depending on the presence of various factors, including infectious agents such as Hp and EBV and genetic factors of the subject.

Nowadays, the striking numbers of infertile couples that turn to assisted reproductive technologies (ART) drive the research toward a more comprehensive understanding of the underlying causes. Male factors contribute to the inability to conceive in half of the cases, and it has been suggested that sexually transmitted infections could have a role in the onset of spermatozoa impairments. Since the impact of HPV infection on sperm quality and sperm DNA integrity is debated, we wanted to analyze its impact on conventional seminal parameters and the sperm DNA fragmentation index (DFI). Therefore, 117 semen samples of patients undergoing IVF were evaluated for the following characteristics: HPV DNA detection and sperm DNA fragmentation, concentration, motility, and morphology. The results showed a higher rate of HPV-negative patients (59.8% vs. 40.2%) and no HPV-related effect on DFI, sperm concentration, total sperm number, and total motility. Only progressive motility and morphology were found as significantly influenced by HPV positivity. Moreover, we observed a statistically significant difference in DFI when comparing high-risk HPV (HR-HPV) and low-risk HPV (LR-HPV) genotypes. Our data suggest that the presence of any HPV type, whatever the exact localization of the virions, can impair some sperm parameters, while HR-HPVs specifically affect the integrity of spermatozoa DNA.

P16 immunostaining is considered a useful surrogate of transcriptionally active high-risk (hr) HPV infection. Only strong and widespread "block-like" immunoreactivity is considered specific, whereas weak/focal p16 positive immunostaining is considered not specific, and follow-up and HPV molecular detection is not indicated. The aim of the study was to evaluate the presence of HPV DNA and Ki67 immunostaining in 40 cervical atypical biopsies (CALs) with mild and focal histological features suggestive of HPV infection-20 cases with weak/focal p16 positive immunoreactivity and 20 cases negative for p16 expression. In 16/20 weak/focal p16 positive CALs (80%), the INNO-LiPA HPV genotyping detected hrHPV genotypes (HPV 31, 51, 56, 59, 26, 53, 66, 73, and 82). Co-infection of two or more hrHPV genotypes was often evidenced. HPV16 and 18 genotypes were never detected. Ki67 immunostaining was increased in 10/20 cases (50%). In 19/20 p16 negative CALs, hrHPV infection was absent and Ki67 was not increased. These results suggest that weak/focal p16 immunostaining represents the early stage of transcriptionally active infection, strongly related to the presence of less common hrHPV genotypes, probably with a slower transforming power, but with a potential risk of progression if the infection persists. HPV DNA genotyping and follow-up could be useful in these cases to verify if they are able to evolve into overt dysplastic changes and to improve knowledge of less common hrHPV genotypes.

The aim of this study was to evaluate HPV status in oral squamous cell carcinoma (OSCC), as coded by the latest classifications and applying a combination of detection methods used in clinical practice. Forty-two patients with suspect OSCC were consecutively recruited. Patients underwent an incisional biopsy for histological OSCC diagnosis and HPV identification by PCR DNA and p16 IHC. All lesions were coded by the latest ICD-0-3.2 site/histology classifications, as proposed for OSCC by the National Cancer Institute Surveillance, Epidemiology and End Results Programs. Moreover, a comparative analysis review, critically evaluated by the same site-coded systems and HPV detection methods, was performed. In 40 confirmed cases of OSCC, the frequency of HPV infection was 10% (4/40). Among positive patients, two cases were PCR DNA/p16 IHC positive (high-risk HPV 51, high-risk HPV 67), two cases were PCR DNA positive/p16 IHC negative (high-risk HPV 31 + 68, high-risk HPV 66). Applying the latest site coding systems for OSCC, the frequency of HPV infection in this study and in similar, reviewed investigations was low (from 3.3% to 12.5%). These results suggested no significant HPV role in oral carcinogenesis, particularly where an updated site-coded classification of OSCCs (categorically excluding the base of the tongue) had been performed.

Introduction: Burn pits (BPs) have been widely used by the U.S. military for waste disposal while in conflicts abroad. Significant adverse health effects are thought to be linked to BPs, but limited data exist examining the impact on the respiratory tract. The purpose of this systematic review is to characterize these effects on both the upper respiratory tract (URT) and lower respiratory tract (LRT)., Materials and Methods: A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines on articles published from January 1, 2001, through November 2020. PubMed, EMBASE, and Ovid MEDLINE databases were queried for studies examining the effect of BPs on the URT and LRT of service members., Results: A total of 288 articles were identified, with nine meeting inclusion criteria. Eight of the nine articles assessed the LRT, one examined the URT alone, and two examined both the URT and LRT. Outcome measures were heterogeneous across all studies, precluding meta-analysis. Patient-reported LRT diagnoses appeared to increase as exposure to BPs increased. There are very limited data assessing the impact of BP exposure on the URT. No association between BP exposure and objective measures of LRT or URT disease was identified., Conclusion: Service members deployed to combat zones seem to report a significant increase in respiratory diseases following exposure to BPs, although definitive conclusions are limited by multiple airborne exposures and varied reporting methods. Self-reported LRT diagnoses appear to be more prevalent. There is a paucity of data on the effects of BPs on the URT. Objective measures of disease do not appear to correlate with patient reports. Prospective, long-term, and outcome-based studies are necessary to examine the effects of BPs, and other airborne hazards related to deployment, on the URT and LRT of service members., (© The Association of Military Surgeons of the United States 2021.

COVID-19 is a current global threat, and the characterization of antibody response is vitally important to update vaccine development and strategies. In this study we assessed SARS-CoV-2 antibody concentrations in SARS-CoV-2 positive patients (N = 272) and subjects vaccinated with the BNT162b2 m-RNA COVID-19 vaccine (N = 1256). For each participant, socio-demographic data, COVID-19 vaccination records, serological analyses, and SARS-CoV-2 infection status were collected. IgG antibodies against S1/S2 antigens of SARS-CoV-2 were detected. Almost all vaccinated subjects (99.8%) showed a seropositivity to anti-SARS-COV-2 IgG and more than 80% of vaccinated subjects had IgG concentrations > 200 AU/mL. In a Tobit multivariable regression analysis, SARS-CoV-2 vaccination was statistically significantly associated with increased IgG concentrations (β coef = 266.4; p < 0.001). A statistically significant reduction in SARS-CoV-2 IgG concentrations was found with older age (β coef = -1.96 per year increase; p < 0.001), male sex (β coef = -22.3; p < 0.001), and days after immunization (β coef = -1.67 per day increase; p < 0.001). Our findings could support the vaccination campaigns confirming the high immunogenicity of the SARS-CoV-2 vaccine under investigation with respect to the natural infection. Further studies will be required for evaluating the role of age and days after immunization in the persistence of vaccine antibodies and protection from the disease.

Sexually transmitted infections (STIs) are a serious global health problem. In Italy, data describing the vulnerability to STIs of specific sexual minorities and the influence of sociodemographic and behavioral determinants are limited, as most infections are not subject to mandatory notification. This retrospective study describes the sociodemographic profile and main sexual behaviors of patients attending a hospital in Palermo (Sicily, Italy) from January 2018 to March 2019 as predictors of STI risk. Patients were divided in subgroups: men-who-have-sex-with-men (MSM), men-who-have-sex-with-women (MSW), bisexual men and females. Data were obtained through an anonymous questionnaire. Patients were tested for chlamydia, syphilis, Mycoplasma genitalium infection, genital herpes and HPV infection. A total of 294 subjects with STIs (male/female ratio about 2:1) were screened. Of the total sample, 79.6% of patients were Italian. MSM accounted for 34.3%, MSW for 29.6%, bisexual men for 5.8% and females for 30.3%. A total of 44.5% of patients had a high education level, 42.5% reported irregular use of condoms, 20.7% reported having had 5-10 partners in the six months prior to the visit and 32.9% were HIV-positive. HPV infection and syphilis were the most prevalent STIs. Conclusions: The most common profile of patients attending our clinic was that of an adult, Italian man with a high level of education, poor use of condoms and a high number of partners. MSM had the highest sex-behavior-related risk for STIs. In addition, our results suggest that all STD teams need to implement counselling topics and recommendations to share with patients, as well as tips on how to approach sexual health education/counselling, thereby promoting patient-centered approaches and educational programs.

Purpose: To evaluate the correlation between the DNA Fragmentation Index (DFI) and sperm morphology in patients undergoing ICSI, as a predictive parameter in reproductive outcomes., Methods: A retrospective study was conducted on 125 infertile patients enrolled in a fertility clinic. Seminal characteristics were measured following the WHO guidelines (2010) for the examination of the seminal fluid. After collecting motile sperm population by pellet swim up, DFI was calculated and simultaneously associated with sperm morphology using in situ TUNEL assay and an image analyzer software in at least 250 spermatozoa for each patient., Results: All subjects were divided into two groups according to a cutoff established, by choice, of the sperm DFI (15%): group A (< 15%) consisting of 65 patients and group B (≥ 15%) of 60 patients. Data were analyzed using non-parametric statistical methods. The results demonstrate that there is no statistical difference between the two groups in seminal characteristics. The collective data show a high significant correlation, suggesting that spermatozoa with abnormal morphology are the best candidates to contain DNA damage (p < 0.001). Also, when group A is compared with group B, an increased percentage of morphologically normal spermatozoa with fragmented DNA was observed in patients, with DFI values ≥ 15% (p < 0.001)., Conclusion: These results are aimed at providing an exact value of DFI in morphologically normal spermatozoa, which will be helpful to the embryologist in evaluating the risk of transferring, during the ICSI procedure, a spermatozoon whit normal morphology but fragmented DNA.

This article considers the role of non-binding legal instruments adopted in Italy against the SARS-CoV-2 virus in the early months of 2020. To verify whether the use of such instruments restricted fundamental and human rights beyond constitutional and legal limits, the article first gives an overview of hard law measures adopted in Italy against the coronavirus. It then focuses on soft law measures, the use of which became significant only in Phase II of Italy's response to COVID-19 and argues that non-binding legal instruments provided the public with instructions on gradually returning to normal life. This contribution contains case studies on the soft law measures adopted in relation to private economic enterprise and freedom of worship. Italian soft law deployed during the COVID-19 epidemic was borne out of coordination between the state and the Regions and as the result of (even informal) dialogue with the relevant stakeholders. Despite some criticism of the soft law measures used, their role in restricting constitutionally granted rights was marginal, because only hard law measures adopted nationally and locally limited personal rights and freedoms in order to contain the pandemic., (© The Author(s) 2021.)

Human papilloma virus infection (HPV) is the most common sexually transmitted disease. Little is known about male infection. Nonavalent vaccine against types 6/11/16/18/31/33/45/52/58 was approved and neutral gender immunization programs have been proposed. This study evaluates the potential impact of nonavalent vaccine compared to quadrivalent in male living in Sicily (Italy). 58.7% of samples were HPV positive and forty-four types of HPV were identified. A significant higher estimated coverage of nonavalent vaccine than quadrivalent was observed (64.3% vs. 45.8%), with absolute and relative additional impact of 20.1% and 47.2%, respectively. Low impact of the vaccine were calculated as the empirical probability of HPV genotypes 6/11/16/18/31/33/45/52/58 alone or in combination; the high impact as empirical probability of HPV6/11/16/18/31/33/45/52/58 genotypes alone or in association with other genotypes. The potential impact of the nonavalent vaccine vs quadrivalent was significant for low and high impact (29.7% > 18:8%; 34:6% > 26.6%, respectively). Particularly, in men with lesions and risky sexual contact was significant only for low impact (35.5% > 29.7%; 31.4% > 19.7%, respectively). In partners with positive females was significant for low impact (26.3% > 15.1%) and high impact (33.7% > 23.2%). Nonavalent vaccine offers broader protection in men with HPV positive partners, who would have a potential role in the transmission of the infection.

Abstract: Orthognathic surgery utilizing a Le Fort I osteotomy is performed by oral and maxillofacial surgeons to correct midface and dental occlusal abnormalities. However, the potential sequelae on sinonasal function have had minimal discussion in the literature. The objective of this study was to assess the impact on nasal septum anatomy and physiology following Le Fort I osteotomy for maxillary repositioning surgery. Thirty patients who previously underwent elective orthognathic surgery with Le Fort I osteotomy were enrolled retrospectively to assess the change in their nasal septal anatomy and nasal breathing. Pre- and postoperative computed tomography (CT) scans were used to determine axial displacement of the septum, in both degrees and millimeters, at 4 different standardized anatomic sites following the surgery. These objective anatomic measurements were then compared to the patient's perception of nasal congestion and difficulty breathing via the validated Chronic Sinusitis Survey-Duration Based (CSS-D). Comparison of the CTs before and after surgery demonstrated a new deviation of the nasal septum in all 30 patients, with maximal axial displacements up to 7.22 mm and a mean of 2.64 mm. Postoperative angular displacement changes ranged from minimal to 24°. The CTs showed persistence of a new septal perforation in 20% (6 of 30 patients) following surgery. The CSS-D results demonstrated a mean worsening of nasal breathing and congestion scores from 1.4 before surgery to 3.0 at least 8 weeks after surgery (P < 0.001). Orthognathic surgery utilizing Le Fort I osteotomy may result in persistent nasal septal perforations, new displacement of the nasal septum, and increased perception of nasal dyspnea not previously reported. Further understanding of anatomic changes and nasal airway obstruction that may be caused following such operations warrants further study in order to improve surgical technique and postoperative outcomes., Competing Interests: The authors report no conflicts of interest., (Copyright © 2020 by Mutaz B.

Introduction : Human papillomaviruses (HPVs) are common sexually transmitted pathogens, causally associated with cervical cancer and other anogenital cancers, as well as approximately 20% of head and neck cancers. The HPV vaccine is an exceptional primary prevention tool, but the question of adequate secondary-prevention strategies remains open. The aim of this review is to better clarify the role of carrageenan in HPV prevention-strategies. Areas covered : A comprehensive literature search was performed (PubMed/MEDLINE, Embase, Google Scholar, Cochrane Databases) to identify articles on the use of carrageenan against HPV infection. The studies were identified using combinations of the search terms 'carrageenan,' 'papillomavirus,' 'HPV,' including only English language papers. Expert opinion : Our review data confirmed the 'inhibitory role' of carrageenan against HPV- pseudoviruses infection on different cell types. The most accredited mechanism to explain this effect involves the direct binding of CG to the viral capsid creating a 'physical' obstacle. However, a different susceptibility to carrageenan for different HPV types has been highlighted, suggesting the possibility of other strategies to infect the host. There are also relevant emerging data regarding the possible role of carrageenan as an adjuvant for antigen-specific immune responses and antitumor effects.

Objective: to investigate the reliability of laryngeal reflux finding score (RFS) and symptom index (RSI) in assessing gastroesophageal reflux (GER) in children and infants., Methods: patients with laryngeal or respiratory symptoms, who underwent laryngoscopy and esophageal pH-impedance (MII-pH) were recruited. RSI and RFS were correlated to MII-pH results. A RSI>13, RFS>7, acid exposure index>7%, total reflux episodes>100/24 h in infants or>70/24 h in children, or a positive symptom index or association probability, were considered pathological. Analysis considering age (12 months) was performed. Sensitivity, specificity, positive (PPV) and negative predictive values (NPV) of the laryngeal scores were calculated., Results: 197 children (median 53 months, 61 infants) were enrolled. MII-pH was pathological in 5/10 patients with RFS>7, and in 17/31 with RSI>13. RFS>7 had 3.9% sensitivity, 93% specificity, a PPV of 50 and a NPV of 34 in predicting GER disease. RFS was inversely associated to weakly acidic and proximal GER. RSI>13 had 13% sensitivity, 83% specificity, and a PPV and NPV similar to RFS. RSI was significantly associated with the number of acid reflux episodes, and, in infants, with bolus exposure index., Conclusions: RSI and RFS aren't accurate in predicting GER in infants and children. Acid reflux relates to laryngeal symptoms, but neither acid, nor proximal and weakly acidic GER relate to laryngeal alterations., Competing Interests: Declaration of Competing Interest Authors declare no conflict of interest related to this paper., (Copyright © 2020 Editrice Gastroenterologica Italiana S.r.l.

The identification of veterans receiving care in community-based settings is important and has implications for healthcare delivery and workforce training and development. As part of a larger collaboration regarding the delivery of behavioral health services, this project partnered a Midwest Veterans Affairs Medical Center with a state primary care association and large federally qualified health center (FQHC) to standardize the method in which veteran status is captured in clinic. Before adapting the screening item and implementing it as a required field in the electronic medical record, the number of veterans reported was 56, or 0.32% of total patients. After implementation, that number increased to 506, or 3.01% of total patients. This suggests there is a need to standardize the method in which veteran status is collected, which has implications for awareness of conditions likely to impact veterans and may inform opportunities for providers to engage in veteran-centric education and training.

Background: Delayed-onset muscle soreness (DOMS) is a specific symptom that typically arises after unaccustomed eccentric muscular effort. It increases typically 24-72 h post-exercise and can affect physical performance. The pathophysiology of DOMS remains unclear, although it seems to be related to the remodeling phase of myofibrils. Different types of treatments have been proposed to minimize DOMS after exercise; however, no clear gold standard treatment exists. Among the most popular and easy-to-apply treatments, manual massage is often performed by clinicians and has been documented to be effective in reducing symptoms. For several years, long-wave diathermy (LWD) has been performed to manage musculoskeletal complaints, such as DOMS; however, no studies have reported its efficacy thus far.This study aimed to compare the clinical effectiveness of LWD, sham LWD, and manual massage in participants with lower limb DOMS., Methods: Participants with lower limb DOMS were included in the study. They were randomly assigned to undergo real LWD, sham LWD, or manual massage. The Numeric Pain Rating Scale (NPRS) score was the primary outcome, and the Patient Global Impression of Change (PGIC) Scale score was the secondary outcome. Outcomes were collected before and immediately after the treatment. Analysis of variance was performed to compare the post-treatment NPRS value variability among the groups and to compare the pre- and post-treatment NPRS differences among the groups., Results: No clinically relevant differences were observed regarding the NPRS value variability among real LWD, sham LWD and manual massage groups. Differences were observed in the PGIC Scale scores., Conclusions: Future studies are needed to have a better understanding about the treatment of DOMS in clinical practice., Trial Registration: The trial was registered on 29th February 2016 in ClinicalTrials.gov (NCT02693678)., Competing Interests: Competing interestsThe authors declare that they have no competing interests., (© The Author(s). 2020.)

Introduction: Helicobacter pylori and Epstein-Barr virus (EBV) infection have recently been shown to be associated with gastric diseases. Polymorphisms in genes encoding cytokines such as interleukin 10 (IL-10) and interleukin 1 Receptor (IL-1RN) influence cytokine secretion levels and appear to contribute to the risk of developing gastroduodenal diseases. To our knowledge, this is the first preliminary study to address the association of coinfection with H. pylori and EBV and their correlation with genetic predisposition in the development of gastric diseases., Methods: Gastric biopsy samples of 96 patients with different gastric diseases were used., Results: Our results showed that the rate of coinfection was higher in patients with gastric cancer than in patients with normal gastric mucosa, active chronic gastritis, and MALT lymphoma. As regards the characterization of H. pilory strains, the polymorphism s1m1i1 of vacA gene was more frequent in patients with MALT Lymphoma in comparison to others, while the polymorphism s2m2i2 was most frequent in patients with normal gastric mucosa. In addition, patients who tested positive for the cagA gene were more frequently those affected with gastric cancer than those with inactive chronic gastritis. Similarly, the patients with oipA gene ON were more frequently those with gastric cancer than those with inactive chronic gastritis., Conclusion: According to our analysis, there was no correlation between coinfection and polymorphisms in genes encoding IL-10 and IL-1RN. We conclude that various factors can be involved in the development of gastric diseases., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2019 Fasciana Teresa et al.)

Orthognathic surgery utilizing a Le Fort I osteotomy is performed regularly by oral surgeons to correct midface and dental occlusal abnormalities, yet little has been written discussing the impact these operations may have on sinonasal function. The objective of this study was to assess the incidence of objective sinonasal inflammation and subjective sinonasal symptoms following the use of Le Fort I osteotomies for maxillary advancement surgery.Thirty-eight subjects who previously underwent Le Fort I osteotomies for purposes of elective orthognathic surgery were enrolled retrospectively to assess for evidence of rhinosinusitis (RS). Post-operative and, when available, preoperative maxillofacial computed tomography (CT) scans were obtained and evaluated using Lund Mackay scoring (LMS). The Chronic Sinusitis Survey - Duration Based (CSS-D) was completed to compare subjective symptoms before and after surgery.Evaluation of the CT scans demonstrated radiographic evidence of RS and subjective worsening of symptoms in 87% and 89% respectively. The mean CSS-D pre- and post-operative scores were 7.6 and 14.8 respectively (P < 0.0001). The mean calculated LMS was 3.39 (2.38-4.40, 95% C.I.). Further sub-analyses demonstrate an increase in both radiographic LMS and subjective CSS-D for patients who had persistent inferior meatal antrostomies after Le Fort I osteotomy.Le Fort I osteotomies performed during orthognathic surgery result in a higher prevalence of post-operative RS than what has been previously described. A better understanding of sinonasal mucocilliary function and the aberrancy that may be caused following such operations deserves further evaluation in order to identify and optimize postsurgical outcomes.

Background: Legionella pneumophila (Lp) is the most common etiologic agent causing Legionnaires' Disease (LD). Water systems offer the best growth conditions for Lp and support its spread by producing aerosols. From 2015 to 2017, the Regional Reference Laboratory of Clinical and Environmental Surveillance of Legionellosis of Palermo monitored the presence of Lp in nine prisons in Western Sicily. During this investigation, we compared Lp isolates from environmental samples in a prison located in Palermo with isolates from two prisoners in the same prison., Methods: We collected 93 water samples from nine Sicilian prisons and the bronchoalveolar lavages (BALs) of two prisoners considered cases of LD. These samples were processed following the procedures described in the Italian Guidelines for the Prevention and Control of Legionellosis of 2015. Then, genotyping was performed on 19 Lp colonies (17 from water samples and 2 from clinical samples) using the Sequence-Based Typing (SBT) method, according to European Study Group for Legionella Infections (ESGLI) protocols., Results: Lp serogroup (sg) 6 was the most prevalent serogroup isolated from the prisons analyzed (40%), followed by Lp sg 1 (16%). Most of all, in four penitentiary institutions, we detected a high concentration of Lp >10 4 Colony Forming Unit/Liter (CFU/L). The environmental molecular investigation found the following Sequence Types (STs) in Lp sg 6: ST 93, ST 292, ST 461, ST 728, ST 1317 and ST 1362, while most of the isolates in sg 1 belonged to ST 1. We also found a new ST that has since been assigned the number 2451 in the ESGLI-SBT database. From the several Lp sg 1 colonies isolated from the two BALs, we identified ST 2451., Conclusions: In this article, we described the results obtained from environmental and epidemiological investigations of Lp isolated from prisons in Western Sicily. Furthermore, we reported the first cluster of Legionnaires' in an Italian prison and the molecular typing of Lp sg 1 from one prison's water system and two BALs, identified the source of the contamination, and discovered a new ST.

Extra-intestinal E. coli are emerging as a global threat due to their diffusion as opportunistic pathogens and, above all, to their wide set of antibiotic resistance determinants. There are still many gaps in our knowledge of their origin and spread pathways, although food animals have been adjudicated vehicles for passing mult-drug resistant bacteria to humans. This study analyzed 46 samples of meat purchased from retail stores in Palermo in order to obtain quinolone-resistant E. coli isolates. Strains were screened for their phylogenetic groups, ST131-associated single nucleotide polymorphisms (SNPs), and then typed by ERIC-PCR. Their set of virulence factors, namely, kpsMII, papA, sfaS, focG, iutA, papC, hlyD , and afa genes, were investigated and their fluoroquinolone-resistance determinants evaluated. The data obtained show a dramatically high prevalence of multidrug resistance patterns in the Palermo area, with 28% of the isolates having virulence factor genes typical of ExPEC strains. No B2 group or ST131 strains were detected. Moreover, 20% of our isolates showed positivity to all the plasmid-mediated quinolone resistance (PMQR) determinants, showing a potential to transfer these genes among other bacteria. Therefore, these data underline the possibility that food animals and, specifically, poultry in particular may be a significant source of resistant bacterial strains, posing a potential zoonotic risk.

Background: Rural areas have historically struggled with shortages of healthcare providers; however, advanced communication technologies have transformed rural healthcare, and practice in underserved areas has been recognized as a policy priority. This systematic review aims to assess reasons for current providers' geographic choices and the success of training programs aimed at increasing rural provider recruitment., Methods: This systematic review (PROSPERO: CRD42015025403) searched seven databases for published and gray literature on the current cohort of US rural healthcare practitioners (2005 to March 2017). Two reviewers independently screened citations for inclusion; one reviewer extracted data and assessed risk of bias, with a senior systematic reviewer checking the data; quality of evidence was assessed using the GRADE approach., Results: Of 7276 screened citations, we identified 31 studies exploring reasons for geographic choices and 24 studies documenting the impact of training programs. Growing up in a rural community is a key determinant and is consistently associated with choosing rural practice. Most existing studies assess physicians, and only a few are based on multivariate analyses that take competing and potentially correlated predictors into account. The success rate of placing providers-in-training in rural practice after graduation, on average, is 44% (range 20-84%; N = 31 programs). We did not identify program characteristics that are consistently associated with program success. Data are primarily based on rural tracks for medical residents., Discussion: The review provides insight into the relative importance of demographic characteristics and motivational factors in determining which providers should be targeted to maximize return on recruitment efforts. Existing programs exposing students to rural practice during their training are promising but require further refining. Public policy must include a specific focus on the trajectory of the healthcare workforce and must consider alternative models of healthcare delivery that promote a more diverse, interdisciplinary combination of providers.

While bivalent and quadrivalent HPV vaccines have been used for about 10 years, a nonavalent vaccine against HPV types 6/11/16/18/31/33/45/52 and 58 has been recently approved by FDA and EMA and is now commercially available. The objective of our study was to evaluate the potential impact of the nonavalent vaccine on HPV infection and related low- and high-grade squamous intraepithelial lesions (LSIL, HSIL), compared to the impact of the quadrivalent vaccine, in a female population living in Sicily (Italy). Low estimates of HPV vaccine impact were calculated as prevalence of HPV 6/11/16/18/31/33/45/52 and 58 genotypes, alone or in association, but excluding presence of other HPV types; high estimates were calculated as prevalence of HPV 6/11/16/18/31/33/45/52 and 58 genotypes alone or in association, in the presence of other HPV types. The nonavalent HPV vaccine showed increased impact, compared to the quadrivalent vaccine. Estimates of potential impact varied from 30.9% (low estimate) to 53.3% (high estimate) for LSIL, and from 56.9% to 81,0% for HSIL. The proportion of additional cases potentially prevented by the nonavalent vaccine was 14.4%-23.8% for LSIL, and 19.0%-32.8% for HSIL. The benefit of the nonavalent vaccine compared to the quadrivalent vaccine was more than 80% for both low and high impact estimates for LSIL and more than 50% for both low and high impact estimates for HSIL. The present study confirms that the switch from a first generation HPV vaccines to a nonavalent vaccine would increase the prevention of cervical HSIL in up to 90% of cases.

Background: Pain drawings (PD) are frequently used in research to illustrate the pain response to pain provocation tests. However, there is a lack of data on the reliability in defining the extent and location of pain. We investigated the test-retest reliability in reporting an acute painful sensation induced by a pain provocation test using a novel approach for PD acquisition and analysis in healthy volunteers., Methods: Forty healthy volunteers participated. Each participant underwent 2 upper limb neurodynamic tests 1 (ULNT1), once to the point of pain onset (PO) and once until the point of submaximal pain (SP). After each ULNT1, participants completed 2 consecutive PD with an interval of 1 minute. Custom software was used to quantify the pain extent and analyze the pain overlap. The test-retest reliability of pain extent was examined using Intraclass Correlation Coefficient (ICC 2,1 ) and Bland-Altman plots. Pain location reliability was examined using the Jaccard similarity coefficient (JSC)., Results: The ICC values for PO and SP were 0.98 (95% CI: 0.96-0.99) and 0.97 (95% CI: 0.95-0.98), respectively. The mean difference and 95% limits of agreement (± 1.96 SD) in the Bland-Altman plots were 14 pixels (-1080;1110) for PO, and 145 (-1610;1900) for SP. The median JSCs (Q1;Q3) were 0.73 (0.64;0.80) for PO and 0.76 (0.65;0.79) for SP., Conclusions: Pain drawings is a reliable instrument to investigate pain extent and pain location in healthy individuals experiencing an acute painful sensation induced by a pain provocation test., (© 2016 World Institute of Pain.)

In August 2015, Dipodascus capitatus was isolated from two patients admitted to the neonatal intensive care unit. Nosocomial acquisition of the fungus was suspected and epidemiological studies were undertaken. The patients were simultaneously hospitalized, and the comparison of the two isolates by two independent molecular typing methods have confirmed clonal dissemination of a single strain of D. capitatus. Antimicrobial susceptibility testing was useful for identifying the appropriated antifungal therapy in micafungin. To our knowledge these are the first described cases of neonatal D. capitatus infection and also the first report of successful treatment by micafungin.

Objective: To describe the use of contrast-enhanced ultrasonography (CEUS) for the detection of active renal hemorrhage in a dog with spontaneous kidney rupture resulting in hemoperitoneum., Case Summary: A 9-month-old, sexually intact male Boxer dog presented for acute collapse, abdominal pain, and tachycardia. Physical examination findings were consistent with hypovolemia and acute abdomen. B-mode ultrasonography revealed peritoneal effusion and a right kidney mass. Subsequently, a CEUS study was performed on the right kidney, which demonstrated active hemorrhage from that kidney resulting in both hemoretroperitoneum and hemoperitoneum. At exploratory surgery, ultrasonographic findings were confirmed and a right nephrectomy was performed. Histopathology demonstrated severe parenchymal alterations along with the presence of nematode larvae. Fecal and urine testing for the presence of parasitic ova were negative. Identification of the larvae was inconclusive. At 30 days postoperatively, repeat B-mode ultrasound and clinicopathologic testing was unremarkable. The dog was alive at 1 year postsurgery with no ill effects., New or Unique Information Provided: To the authors' knowledge, this is the first report of CEUS for the detection of active hemorrhage from a kidney resulting in hemoretroperitoneum and hemoperitoneum in a dog. Although rare, the finding of nematode larvae within the renal parenchyma may have been the cause of kidney rupture. Importantly, surgical removal of the kidney was curative. Benign processes causing kidney rupture such as parasitic infestation should be considered in the working diagnosis as related to geographical location., (© Veterinary Emergency and Critical Care Society 2015.)

In recent years, the popularity of ultramarathons has increased. During these competitions, musculoskeletal problems are very common. Among the more frequent of those problems is the onset of muscle pain, which is defined in the literature as delayed-onset muscle soreness (DOMS). The present study aimed to collect epidemiological data regarding the onset of musculoskeletal problems during the Tor des Geants (International ultramarathon race of 330 km in length and 24,000 m in elevation difference) and to describe the effects of massage on reducing pain and overall perceived improvement in a sample of 25 athletes who complained of DOMS. Two hundred and twenty-one treatments were performed on 220 ultramarathon runners, of which 207 were males and 34 were females; the age group most represented ranged from 40 to 50 years. The most common symptom was pain, which occurred in more than 95% of cases, and the most affected area was the lower extremities (90% of subjects). In the analysed subjects, treatment with massage generated a significant (p < 0.0001) improvement. The numeric pain rating scale (NPRS) value was 3.6 points on average (SD 2.1) after massage, and there were no cases of worsening DOMS after massage as determined using the patient global impression of change (PGIC). The values of minimal clinically important difference (MCID) in DOMS management were calculated on the basis of the ROC curves and two other anchor-based methods in the PGIC and were 2.8-3.9 points on the NPRS. In the context analysed, massage was an effective treatment to reduce DOMS during the onset of symptoms., (Copyright © 2014 Elsevier Ltd. All rights reserved.)

Importance: Several studies have documented the prevalence and treatment of orbital complications secondary to pediatric rhinosinusitis, but to our knowledge, none have investigated the national health care burden of this disease since the introduction of the heptavalent pneumococcal vaccine (PCV-7)., Objective: To identify the current public health burden of orbital complications of pediatric rhinosinusitis, and to determine if the introduction of the PCV-7 has resulted in a change in national practice patterns., Design, Setting, and Participants: Population-based study using the 2000 and 2009 Kids' Inpatient Databases to gather data on a sample of all pediatric discharges in the United States during the years 2000 and 2009. Children diagnosed as having orbital complications of sinusitis were identified by corresponding International Classification of Diseases, Ninth Revision (ICD-9) codes. Database analyses generated national estimates of summary statistics and comparison of trends over the 9-year period., Interventions: Database analysis., Main Outcomes and Measures: National health care trends according to year. End points assessed included prevalence, age, sex, length of hospital stay, and treatment of disease., Results: The estimated prevalence of orbital complications of sinusitis requiring hospitalization in the United States has slightly decreased from 5338 (95% CI, 4956-5720) admissions in 2000 to 4511 (95% CI, 4165-4858) in 2009. However, the mean age has increased from 4.77 (95% CI, 4.56-4.97) years to 6.07 (95% CI, 5.87-6.26) years. The proportion of children undergoing surgical treatment increased from 0.108 (95% CI, 0.093-0.123) to 0.195 (95% CI, 0.176-0.213). Total charges increased from $4,140,000 (95% CI, $3,440,000-$4,830,000) to $10,000,000 (95% CI, $8,480,000-$11,600,000) with a mean charge per admission increasing from $8390 (95% CI, $7096-$9685) in 2000 to $22,656 (95% CI, $19,997-$25,314) in 2009. The mean length of stay remained stable at 3.67 (95% CI, 3.37-3.97) to 4.05 (95% CI, 3.81-4.29) hospital days., Conclusions and Relevance: The public health impact of orbital complications of pediatric rhinosinusitis continues to be substantial. Since the institution of the PCV-7 vaccine, national trends demonstrate a slightly decreased prevalence of hospital admissions. However, there is a shifting trend toward an older age at admission and a higher proportion of children undergoing surgical treatment.

Objectives/hypothesis: To determine if tympanic membrane perforation offers any protection from inner ear damage and determine the incidence and pattern of otologic blast injury in military personnel returning from deployment., Study Design: Retrospective analysis of US service members injured in Operation Iraqi Freedom and Operation Enduring Freedom from October 2006 to October 2007., Methods: One-hundred ten blast-injured patients were compared to 54 nonblast-injured patients returning from deployment. Data captured included audiogram results, presence of tympanic membrane perforation, demographic data, location and nature of injury, loss of consciousness, sleep disturbance, confusion, and symptoms of headache, dizziness, memory loss, and tinnitus., Results: Of 110 blast-injured patients, 18 patients suffered tympanic membrane perforation (16%), of which nine patients suffered bilateral tympanic membrane perforation (8%). Blast patients suffered more hearing loss than controls as measured by pure-tone averages of varying speech reception frequencies and at 6,000 Hz. Of the blast patients who recorded an audiogram, nearly 24% suffered moderate to profound hearing loss. There was no statistically significant difference in hearing outcomes between blast-injured patients with tympanic membrane perforations and those without; however, when comparing patients with unilateral perforations with their contralateral ear, there was a difference in hearing thresholds at 6,000 Hz. There was a significantly increased risk of tinnitus, memory loss, headache, and dizziness between blast-injured patients compared to controls., Conclusions: Due to its violent nature, blast exposure causes greater neuro-otological manifestations and deserves prompt otologic evaluation., (© 2013 The American Laryngological, Rhinological and Otological Society, Inc.)

Objective: To evaluate the prevalence of human papillomavirus (HPV) sperm infection and its correlation with sperm parameters in patients who attended a fertility clinic., Design: Cross-sectional clinical study., Setting: University-affiliated reproductive medicine clinic., Patient(s): A total of 308 male partners of couples undergoing in vitro fertilization techniques., Intervention(s): Specimens of semen were collected from all patients., Main Outcome Measure(s): Sperm parameters were evaluated according to the World Health Organization manual. The presence of HPV DNA was researched by the combined use of two HPV assays and a highly sensitive nested polymerase chain reaction assay followed by HPV genotyping. To examine whether HPV was associated with the sperm, in situ hybridization (ISH) analysis was performed., Result(s): Results of HPV investigation were compared with sperm parameters and ISH analysis. Twenty-four out of 308 semen samples (7.8%) were HPV DNA positive, but HPV infection did not seem to affect semen quality. Moreover, ISH revealed a clear HPV localization at the equatorial region of sperm head in infected samples., Conclusion(s): Oncogenic HPV genotypes were detected on spermatozoa from asymptomatic subjects, but a role of the infection in male infertility was not demonstrated., (Copyright © 2013 American Society for Reproductive Medicine.

The present study aims to assess the evolution of different proto-horizons as embryonic soils built by pedotechnologies for the reclamation and management of derelict and damaged lands, such as abandoned quarries. The model proto-horizons were assembled by utilizing coarse limestone gravel or zeolitized Phlegraean Yellow Tuff (PYT) as mineral components and commercial compost-amendments or a phosphorite-poultry manure mixture as organic matrices for growth of a pasture-grass under controlled conditions. The evolution of the model proto-horizons was followed by an evaluation of the stability and modification of the organic matter (OM) with reference to plant development. The results suggest that the natural carbonatic substrate occurring in limestone quarries was unable to sustain significant plant growth, while the PYT was suitable and efficient as a pedogenic substrate because it supported plant growth and induced a conspicuous accumulation of OM due to root activity. In particular, OM, including humic and non-humic components, greatly increased in the PYT treatment with the phosphorite-poultry manure mixture showing a concurrent trend toward humification. Conversely, an overall tendency toward degradation of OM was detected in the PYT model proto-horizon treated with commercial compost. Feasibility estimates show that quarry restoration costs appear reasonable where environmental impacts are high., (Copyright © 2013 Elsevier Ltd. All rights reserved.)

Human papillomavirus (HPV) 58 accounts for a notable proportion of cervical cancers in East Asia and parts of Latin America, but it is uncommon elsewhere. The reason for such ethnogeographical predilection is unknown. In our study, nucleotide sequences of E6 and E7 genes of 401 HPV58 isolates collected from 15 countries/cities across four continents were examined. Phylogenetic relationship, geographical distribution and risk association of nucleotide sequence variations were analyzed. We found that the E6 genes of HPV58 variants were more conserved than E7. Thus, E6 is a more appropriate target for type-specific detection, whereas E7 is more appropriate for strain differentiation. The frequency of sequence variation varied geographically. Africa had significantly more isolates with E6-367A (D86E) but significantly less isolates with E6-203G, -245G, -367C (prototype-like) than other regions (p ≤ 0.003). E7-632T, -760A (T20I, G63S) was more frequently found in Asia, and E7-793G (T74A) was more frequent in Africa (p < 0.001). Variants with T20I and G63S substitutions at E7 conferred a significantly higher risk for cervical intraepithelial neoplasia grade III and invasive cervical cancer compared to other HPV58 variants (odds ratio = 4.44, p = 0.007). In conclusion, T20I and/or G63S substitution(s) at E7 of HPV58 is/are associated with a higher risk for cervical neoplasia. These substitutions are more commonly found in Asia and the Americas, which may account for the higher disease attribution of HPV58 in these areas., (Copyright © 2012 UICC.)

Infection with High Risk (HR) Human Papillomaviruses (HPVs) is the main aetiological agent of Cervical Squamous Cell Carcinoma (CSCC) and also associated in a subgroup of other neoplasms, including Oropharyngeal Squamous cell Carcinoma (OPSCC). HPV infection, in genital as in oral mucosa, can also be subclinical or associated with benign proliferative lesions (common warts, condylomas, papillomas) caused mostly by infection with Low Risk (LR)-HPVs. In the last decades, extensive research has resulted in growing knowledge on HPV biology and specifically viral life cycle, biochemical properties of viral proteins and their interaction with the host proteins leading to potential new targets of prophylactic or therapeutic vaccines and therapies for HPV infection. In addition, notable progresses have been made in the field of diagnostics to detect HPV DNA or RNA. The recent epidemiological data suggest the significant changes in HPV endemic, due to the changes in sexual habits especially among young generations (i.e. early sexual debuts, multiple sexual partners, oral and anal sex); this scenario has urged on the need of adequate campaigns of primary (sexual education, vaccination programs) and secondary prevention (diagnostics of HPV-related diseases). Due to the growing interest on HPV infection and HPV related cancers, the authors made a narrative review of the literature on oral HPV infection and oral-genital transmission. After this, in view of the controversies about the strategies of therapy and prevention of HPV infection, the present review focuses on the current state of art about the available tools for the therapeutic and, if any, preventive management of oral HPV infection.

Velopharyngeal inadequacy may be learned, neurologic, or anatomic in origin. Velopharyngeal insufficiency specifically refers to an anatomic deficiency, which subsequently impairs resonant control of speech and intraoral pressure for orally directed speech sounds. Preoperative speech therapy is useful, and in some children may provide definitive treatment. However, surgery is the foundation of effective treatment in most patients with anatomic defects and, when used appropriately, has been shown to result in resolution of velopharyngeal insufficiency in 62-98% of cases. In this chapter, the authors review velopharyngeal inadequacy and discuss the techniques necessary for successful surgical treatment., (Copyright © 2012 S. Karger AG, Basel.)

Background: It is well-known that Epstein-Barr virus (EBV) can affect the central nervous system (CNS)., Case Presentation: Herein the authors report unusual timely Magnetic Resonance Imaging (MRI) brain scan findings in an immunocompetent patient with EBV encephalitis. Diffusion weighted MRI sequence performed during the acute phase of the disease was normal, whereas the Fast Relaxation Fast Spin Echo T2 image showed diffuse signal intensity changes in white matter. The enhancement pattern suggested an inflammatory response restricted to the brain microcirculation. Acyclovir and corticosteroid therapy was administered. After three weeks, all signal intensities returned to normal and the patient showed clinical recovery., Conclusion: This report demonstrates that EBV in an immunocompetent adult can present with diffuse, reversible brain white matter involvement in the acute phase of mononucleosis. Moreover, our case suggests that a negative DWI sequence is associated with a favorable improvement in severe EBV CNS infection. More extensive studies are needed to assess what other instrumental data can help to distinguish viral lesions from other causes in the acute phase of disease., (© 2011 Di Carlo et al; licensee BioMed Central Ltd.)

The mongolian spot, nevus of Ota, and nevus of Ito are the most common morphologic forms of the dermal melanocytoses, a group of benign pigmented lesions histologically characterized by the presence of melanocytes within the dermis. Nevus of Ito is clinically distinct, presenting with unilateral, bluish gray, patchy discolorations in the skin within the distributions of the posterior supraclavicular and lateral cutaneous brachial nerves. Although all dermal melanocytoses are generally considered benign, rare cases of malignant transformation associated with nevus of Ota have been described. Only one case of malignant melanoma transformation in association with nevus of Ito has previously been reported. We present the second description of malignant melanoma transformation within a nevus of Ito and provide comment on the malignant potential of the dermal melanocytoses., (Copyright 2009 American Academy of Dermatology, Inc.

Human papillomavirus (HPV) infection is the commonest sexually transmitted infection, and high-risk HPV types are associated with cervical carcinogenesis. This study investigated: the HPV type-specific prevalence in 970 women with an abnormal cytological diagnosis; and the association of HPV infection and cervical disease in a subset of 626 women with a histological diagnosis. HPV-DNA was researched by nested PCR/sequencing and the INNOLiPA HPV Genotyping assay. The data were analysed by the chi-square test (p

The concordance of human papillomavirus (HPV) groups and types was evaluated in 45 sexual couples with both partners HPV infected, by analyzing cervical samples from women and three genital sites (penile brushing, urethral brushing, and semen) from men. When grouping HPV types, no significant HPV group sharing was found between partners, either considering samples from any male site (concordance: 55.5%; P = 0.11) or from each site (concordance by penile brushing, 37.8%; urethral brushing, 24.5%; semen, 22.3%; P > 0.05). Examining individual HPV types, using samples from any male site, concordance was found in 29 (64.4%; P = 0.036) couples; significant concordance was evident for 16 HPV genotypes, the most frequent being HPV-6, -66, -31, -51, and -53. Using samples from specific male sites, concordance was found by penile brushing in 24 (53.3%) couples, urethral brushing in 16 (35.5%), and semen in 7 (15.5%; P = 0.014). Among the 16 HPV types shared by examining samples from any male site, 9 (56.3%) were in common by penile brushing, 11 (68.7%) by urethral brushing, and 6 (37.5%; P = 0.48) by semen. Combined penile brushing and urethral brushing sampling identified all the 29 couples concordant by the three male sites; combined penile brushing and semen detected 26 (89.6%) concordant couples. The most adequate approach to the assessment of HPV concordance in sexual couples could be based on the analysis of individual HPV types and the sampling of men by penile brushing combined with urethral brushing. The high and significant degree of HPV type-specific concordance confirms HPV transmission between sexual partners., ((c) 2007 Wiley-Liss, Inc.)

Methods that used specimens from three genital sites (penile brushing [PB], urethral brushing [UB], and the retrieval of semen [SE]) from 50 men were examined for human papillomavirus (HPV) DNA detection. The rates of detection by PB, UB, SE, PB and UB, and PB and SE were 88.9%, 50.0%, 33.3%, 100%, and 97.2%, respectively. The use of PB and UB appears to be the most accurate method; as an alternative to UB, the use of SE with PB could be used to improve the rate of HPV DNA detection in men.

A retrospective analysis by molecular-sequence-based techniques was performed to correctly identify the etiological agent of 24 Mediterranean spotted fever cases occurring in Western Sicily, Italy, from 1987 to 2001. Restriction analysis of a 632-bp PCR-amplified portion of the ompA gene allowed presumptive identification of five clinical isolates as belonging to Rickettsia conorii subsp. israelensis, the etiological agent of Israeli spotted fever (ISF). The remaining 19 rickettsial isolates were Rickettsia conorii subsp. conorii, the only pathogenic rickettsia of the spotted fever group reported in Italy until the present. Sequence analysis of the ompA gene confirmed the identification of all the R. conorii subsp. israelensis isolates and demonstrated that rickettsiosis caused by R. conorii subsp. israelensis can be traced back to 1991 in Sicily. The recorded clinical data of the five ISF patients support the idea that these strains could correlate to more-severe forms of human disease. Three of five patients experienced severe disease, and one of them died.

To evaluate in oral leukoplakia the relationship between HPV infection and markers of apoptosis (bcl-2, survivin) and proliferation (PCNA), also conditionally to age, gender, smoking and drinking habits of patients, by means of Fuzzy neural networks (FNN) system 21 cases of oral leukopakia, clinically and histologically diagnosed, were examined for HPV DNA presence, bcl-2, survivin and PCNA expression. HPV DNA was investigated in exfoliated oral mucosa cells by nested PCR (nPCR: MY09-MY11/GP5-GP6), and the HPV genotype determined by direct DNA sequencing. All markers were investigated by means of standardised immunohistochemistry procedure. Data were analysed by chi-square test, crude OR and the 95% CI; in blindness, FNN was applied. HPV DNA was found in 8/21 OL (38.1%); survivin, PCNA, and tobacco smoking were associated in univariate analysis (p = 0.04) with HPV DNA status. HPV-18 was the most frequently detected genotype (6/8), followed by HPV-16 (2/8). FNN revealed that survivin and PCNA, both being expressed in all of OL HPV+ve, were associated with HPV infection. In conclusion, the FNN allowed to hypothesise a model of specific variables associated to HPV infection in OL. The relevance of survivin and PCNA suggest that they may be involved in HPV-mediated deregulation of epithelial maturation and, conversely, that HPV may have a role in the expression level of these two markers. FNN system seems to be an effective tool in the analysis of correlates of OL and HPV infection.

Background and Objectives: The current study compared the cervical cytological sub-category "atypical squamous cells of undetermined significance-favour reactive (AFR)", recently recommended to be eliminated by the Bethesda system, to the sub-category "atypical squamous cells of undetermined significance-favour dysplasia (ASC-US)", in terms of prevalence of coexistent squamous intraepithelial lesions of either low-grade (LSIL) or high-grade (HSIL) and rate of human papillomavirus (HPV) infection., Study Design: One hundred women with AFR and 100 with ASC-US were consecutively included in the study. All patients underwent colposcopy, followed by biopsy when necessary, and were screened for HPV infection by the combined use of Hybrid Capture II (DIGENE) and PCR with MY09/11 primers, the latter followed by direct sequencing of the amplifications products for HPV genotyping., Results: LSIL were detected in 5.6% of AFR and 18.5% of ASC-US (p=0.00812), HSIL only in 4.3% of ASC-US. HPV infection was diagnosed in 11.2% of AFR and 38.0% of ASC-US (p=0.00003); high-risk HPV types (namely, HPV-16, -18, -31, -66, -67 and -70) were found in 6.7% of AFR and 22.8% of ASC-US (p=0.00239). Evidence of HPV infection in absence of SIL was proven in 7.1% of AFR and in 22.5% of ASC-US (p=0.00622)., Conclusion: The association of AFR with SIL and high-risk HPV infection is low but not inexistent. Thus, to avoid the risk of leaving some high-risk AFR patients untreated or without follow-up, it could be proposed to keep AFR as a cytological category and to triage it by HPV testing, similarly to what has been already recommended for ASC-US.

The PGMY-PCR for human papillomavirus (HPV) was evaluated, in parallel with nested PCR (nPCR), in samples with noted Hybrid Capture II (HCII) and MY-PCR results. PGMY-PCR detected HPV DNA in 2.5% of HCII-negative-MY-PCR-negative samples and in 71.7% of HCII-positive-MY-PCR-negative samples; also, it detected the MY-PCR-negative-nPCR-negative types HPV-42, HPV-44, HPV-51, HPV-87, and HPV-89.
