1q21.1 Duplication Syndrome and Anorectal Malformations: A Literature Review and a New Case.

Background: Anorectal malformations (ARMs) are a common pediatric surgical problem with an incidence of 1:1500 to 1:5000 live births. The phenotypical spectrum extends from anal stenosis to imperforate anus with or without anal fistula to persistent cloaca. They can manifest as either non-syndromic or syndromic conditions.

Sex differences in response to HBV vaccination in a cohort of health care workers.

Globally, healthcare workers (HCWs) are at greater risk of contracting Hepatitis B virus (HBV) infection than the general population, due to their frequent contact with blood or body fluids. For this reason, WHO underlined the importance of HBV immunization for all HCWs. Although sex is now considered one of the key factors influencing the intensity and duration of the immune response to vaccines, sex-specific analysis of vaccine-induced anti-HBs antibodies is rarely conducted.

Six years of spreading BLSD skills in schools: empowering teachers as trainers.

Introduction: To increase the population's ability to handle emergencies, life-saving maneuvers should be universally acquired as an automatic skill starting from school through frequent and practical retraining. Teachers could be ideal multipliers, but it is necessary to design pathways that train and motivate them, since Basic Life Support and Defibrillation (BLSD) skills are not part of their academic curricula. This study explores innovative training solutions and facilitating factors to enhance BLSD education in schools by focusing on the training and motivation of teachers.

A Case-Control Study on the Effects of Plasticizers Exposure on Male Fertility.

Male infertility is a serious concern for public health, and the possible role of exposure to plasticizers such as phthalates and bisphenol A in contributing to the condition is widely debated. We have herein enrolled 155 infertility cases attending an infertility center and 211 controls (fathers of a spontaneously conceived newborn) to investigate this issue. The urinary levels of seven phthalates and BPA were analyzed through HPLC/MS/MS.

Phthalate Exposure and Biomarkers of Oxidation of Nucleic Acids: Results on Couples Attending a Fertility Center.

Phthalates are substances used as plasticizing agents and solvents that can increase the risk of infertility and that appear to induce oxidative stress. The aim of the study was to show the possible relationship between urinary concentrations of phthalates metabolites, namely MEP, MBzP, MnBP, MEHP, MEHHP, and MnOP and biomarkers of nucleic acids oxidation, methylation, or protein nitroxidation. The oxidative stress biomarkers measured in human urine were 8-oxo-7,8-dihydroguanine, 8-oxo-7,8-dihydroguanosine, 8-oxo-7,8-dihydro-2'-deoxyguanosine, 3-nitrotyrosine, and 5-methylcytidine.

Female Reproductive Health and Exposure to Phthalates and Bisphenol A: A Cross Sectional Study.

The xenoestrogenicity of some plasticisers (phthalates and bisphenol A) is documented in the literature and may pose a risk to female reproductive health. The aim of this study was to assess exposure to six phthalates. This was achieved by measuring their respective metabolites (mono-ethylphthalate (MEP); mono-n-butylphthalate (MnBP); mono-n-ottylphthalate (MnOP); and monobenzylphthalate (MBzP)), as well as the sum of two of the diethyl-hexyl phthalate metabolites-(∑DEHP) and bisphenol A (BPA) in a female population with infertility problems, and by conducting a correlation analysis between infertility factors, work activities, and lifestyle habits, in order to formulate a causal hypothesis.

From Environmental to Possible Occupational Exposure to Risk Factors: What Role Do They Play in the Etiology of Endometriosis?

Endometriosis is a gynecological disorder characterized by the presence of endometrial stroma and glands outside the uterine cavity. A systematic review of the literature was conducted to clarify, starting from environmental exposure data, whether possible occupational risk factors may correlate with the onset of the disease. The guidelines for reporting systematic reviews of the "PRISMA" statement were followed and two databases, Scopus and PubMed, were used.

Cross Sectional Study on Exposure to BPA and Phthalates and Semen Parameters in Men Attending a Fertility Center.

Among the possible risk factors for male reproduction, exposure to phthalates and alkylphenols is widely documented. This study evaluated the possible association between chemical exposure and the quality of the seminal fluid of 105 subjects in a fertility clinic. The urinary levels of seven phthalate metabolites (monoethylphthalate, MEP; monobenzylphthalate, MBzP; mono -butylphthalate, MnBP; mono-(2-ethylhexyl) phthalate, MEHP; mono(2-ethyl-5-hydroxyhexyl) phthalate, MEHHP; mono--octylphthalate, MnOP; mono-isononylphthalate, MiNP) and bisphenol A (BPA), were analysed by high performance liquid chromatography/tandem mass spectrometry HPLC/MS/MS.

Emerging problems and novel skills: a qualitative analysis on the role of occupational physicians.

Introduction: The thorough changes in the world of employment, together with regulatory changes, have made the role of occupational health physicians increasingly complex, with an extension of the prescribing component, linked to the operational aspects of the role, as well as a greater complexity in the discretionary sphere, which also requires a number of "non-technical" skills.

Objectives: This work investigates how occupational physicians experience and represent their role, with special attention paid to the person-context relationship, so as to offer reflections and useful tools for supporting this role within the participatory health and safety system in the workplaces.

Methods: Using a qualitative approach, the survey has been carried out through semi-structured interviews to a sample of 22 Italian occupational health physicians who were asked to talk about their professional experience with regard to the legislative reforms, critical factors in their work, their relationship with other players in the safety system, and satisfaction with Continuous Medical Training (ECM).

Temporal Trends of Urinary Phthalate Concentrations in Two Populations: Effects of REACH Authorization after Five Years.

Phthalates are widely used in the industrial manufacture of many products. Some phthalates have shown reproductive toxicity in humans, acting as endocrine disruptors, so they were included in the authorization process defined in Reg. CE 1907/2006 (REACH).

Teaching Life-Saving Manoeuvres in Primary School.

In the event of sudden cardiac arrest (SCA) early intervention provided by a layperson can be life-saving. Teaching first aid in primary school may increase the lifelong ability and motivation of young people to take action in an emergency. The aim of this article is to report a training experience on BLSD (Basic Life Support and Defibrillation) designed for a group of pupils in an Italian primary school, with assessment of its effectiveness at a distance.

[DIFFERENT APPROACHES FOR CHEMICAL RISK ASSESSMENT IN LABORATORIES].

The aim of this study was to compare the different approaches used for chemical risk assessment, in relation to the perception of riskfor operators, in some research laboratories of a hospital in Rome. All information regarding the chemicals used for the application of three algorithmic models for chemical risk assessment ("Movarisch", "Inforisk", "Archimede") were collected. An environmental and biological monitoring and a study on the combined exposure to multiple chemicals using the World Health Organization proposed steps were carried out.

Expression of PTEN in endometrial liquid-based cytology.

Objectives: Endometrial cytology offers a reliable alternative to biopsy in endometrial cancer detection and it may be useful in obtaining material to study prognostic and predictive markers. Over the years, new sampling devices have been developed. Molecular alterations in endometrial cancers were previously described using formalin-fixed paraffin-embedded tissues with particular attention, in endometrioid carcinomas, to the PTEN-PI3K pathway.

Role of E6/E7 mRNA test in the diagnostic algorithm of HPV-positive patients showing ASCUS and LSIL: clinical and economic implications in a publicly financed healthcare system.

Objective: Colposcopy is widely used to triage women with mild cervical abnormalities. However, this approach is associated with low specificity and predictive value. The efficacy of E6/E7 mRNA test for this purpose has been demonstrated, but studies estimating its cost-effectiveness are still lacking.

Chromogenic in situ hybridization and p16/Ki67 dual staining on formalin-fixed paraffin-embedded cervical specimens: correlation with HPV-DNA test, E6/E7 mRNA test, and potential clinical applications.

Although HPV-DNA test and E6/E7 mRNA analyses remain the current standard for the confirmation of human papillomavirus (HPV) infections in cytological specimens, no universally adopted techniques exist for the detection of HPV in formalin-fixed paraffin-embedded samples. Particularly, in routine laboratories, molecular assays are still time-consuming and would require a high level of expertise. In this study, we investigated the possible use of a novel HPV tyramide-based chromogenic in situ hybridization (CISH) technology to locate HPV on tissue specimens.

Urinary metabolite concentrations of phthalate metabolites in Central Italy healthy volunteers determined by a validated HPLC/MS/MS analytical method.

The main objective of this study was to determine the average concentrations for the metabolites of the four more common phthalates, industrial chemicals widely used in commercial products and potential endocrine disruptors, in the urine of a control population living in Central Italy. The study population consisted of 157 healthy subjects, not occupationally exposed to phthalates (74 males and 83 females). Urinary levels of the analytes were determined by liquid chromatography tandem mass spectrometry (LC-MS/MS) with isotopic dilution.

Implementing specificity of HPV-DNA primary screening in a successful organised cervical cancer prevention programme.

Objective: This two-arm longitudinal study was performed within a regional organized cervical-cancer-prevention program in which HPV-DNA test is used in primary screening. The aim was to analyze the diagnostic performances of p16INK4a/Ki-67 dual-test and E6/E7-mRNA test in identifying CIN2+ lesion among HPV-DNA positive (HPV-DNAve) women triaged for LSIL-or-worse liquid based cytology (LBC).

Methods: Thirty-six thousand thirty-one women participated to HPV-DNA screening program pilot study.

Occupational exposure to styrene in the fibreglass reinforced plastic industry: comparison between two different manufacturing processes.

Background: Styrene is used in manufacturing fiberglass reinforced plastics: and occupational exposure was related to neurotoxicology and genotoxicity. The sum of the metabolites mandelic and phenylglyoxylic acids is the ACGIH biomarker for occupational exposure with a BEI of 400 mg/g of creatinine in end shift urine corresponding to a airborne styrene concentration of 85 mg/m3. There are two main molding processes, open and closed, the last more effective at controlling worker's styrene exposure.

Airway inflammation in professional divers: FeNO as a marker.

Purpose Of The Research: The aim of this present study is examine the airway inflammation using the fractional exhaled nitric oxide (FeNO), to detect differences in FeNO measurements in comparison with spirometry and evaluate the use of this technique in health surveillance programs, also in order to determine the suitability to the specific task.

What Was Done: Between November 2009 and February 2010 we recruited 74 volunteers, all professional divers from the Italian National Fire Services Department. A clinical-medical history questionnaire was administered, with guidance; then the study protocol was applied.

Detection of residual/recurrent cervical disease after successful LEEP conization: the possible role of mRNA-HPV test.

Background: Loop Electrosurgical Excision Procedure (LEEP) represents the mainstay technique for CIN2+ removal. The major concern in conservative treatment is to verify whether CIN eradication was complete, since incomplete excision is associated with an increased risk of cervical cancer. The histopathologic evaluation of resection margins status is far from perfect, since cervical lesions may recur in 5-15% of patients who had conisation specimens with clean margins.

Urinary phthalate monoesters concentration in couples with infertility problems.

The widespread use of phthalates results in human exposure: phthalates are rapidly metabolized to their respective monoesters and other oxidative products, which are glucuronidated and excreted through the urine and feces. Several in vivo studies showed that some phthalates, in particular diethyl-hexyl phthalate (DEHP), diethyl phthalate (DEP), di(n-butyl)phthalate (DnBP) and n-butylbenzylphthalate (BBzP), are able to interact with the human endocrine system, interfering with the reproduction ability. In this study, 56 couples were recruited from a centre of assisted reproduction.

Screening for tuberculosis among homeless shelter staff.

The prevalence of tuberculosis (TB) among homeless shelter staff was assessed using the tuberculin skin test (TST) and the Quantiferon TB-Gold in tube interferon-γ release assay (QFT-TB). Investigation of 51 participants for whom both QFT-TB and TST results were available showed 47.1% and 43.

Exposure to styrene in fiberglass-reinforced plastic manufacture: still a problem.

Objective: The aim of the work is to define occupational exposure to styrene in fiberglass manufacture; the phase of stretching styrene resins needs some manual handling and leads workers to be exposed to styrene.

Methods: We surveyed 20 workers in two companies manufacturing fiberglass, checking environmental levels and urinary concentrations of mandelic acid (MA), and phenylglioxylic acid (PGA). Workers completed a questionnaire collecting their medical history.
