Primary congenital glaucoma surgery: outcomes and visual function

Purpose: To assess the long-term visual outcomes of children with PCG, irrespective of the type of surgical procedure, and to create visual acuity curves to help in predicting the development of visual function in these patients. The secondary aim is to identify associated factors for visual decline or loss, highlighting differences between neonatal and infantile subgroups. Methods: The medical records of pediatric glaucoma patients from 1996 to 2017 at the University Hospital of Verona (Verona, Italy) were retrospectively reviewed. Visual acuities, surgeries, PCG subtype and etiology of vision impairment were recorded. Statistical analyses were performed to detect factors associated with vision decline. Results: Sixty-seven eyes (40 patients) were included in the study. Developmental predictive curves of visual acuity showed that children with infantile PCG had a better visual outcome than children with neonatal PCG at each step of follow-up. A good-to-moderate VA (< 1 LogMAR) was achieved in 56 eyes (83.6%), while 11 eyes (16.4%) had poor VA ( 65 1 LogMAR). The age at onset, sex, number of surgeries, intraocular pressure (IOP) control (with or without antiglaucoma drugs), axial length (AL) and corneal opacities were statistically associated with vision impairment (p < 0.01). The main cause of visual impairment was amblyopia. Conclusions: Visual outcomes of PCG significantly correlate with the age at diagnosis. Although a good long-term IOP control can often be achieved in PCG, often the visual acuity remains below the lower limits of the normal range. Poor vision in childhood is related to global developmental problems, and referral to third-level services should not be delayed to prevent vision impairment. In this regard, visual acuity curves can be a useful tool for the consultant ophthalmologist to define the visual development of children affected by PCG

“Evidence-Based Dentistry in Oral Surgery: Could We Do Better?”

Evidence-based Dentistry (EBD), like Evidence-based Medicine (EBM), was born in order to seek the “best available research evidence” in the field of dentistry both in research and clinical routine

The Accuracy of Computer-Assisted Implant Surgery Performed Using Fully Guided Templates versus Pilot-Drill Guided Templates

Purpose. Computer-assisted stereolithographically guided surgery allows an ideal implant placement for prosthetic restoration. Two types of stereolithographic templates are currently available: a fully guided template and a pilot-drill guided template. The purpose of this study was (i) to evaluate the accuracy of implant insertion using these types of surgical templates and (ii) to define parameters influencing accuracy. Materials and Methods. 20 patients were enrolled and divided into 2 study groups: in group A, implants were placed using CAD-CAM templates with fully guided sleeves; in group B, implants were placed with a template with only pilot-drill guided sleeves. Pre- and postoperative computed tomographies were used to measure differences between final positions of implants and virtually planned positions. Three linear discrepancies (coronal, apical, and depth) and two angular ones (buccolingual and mesiodistal) were measured. Correlations between accuracy and jaws of interest, implant length and diameters, and type of edentulism were also analysed. Results. A total of 50 implants were inserted in 15 patients using CAD-CAM templates: 23 implants in group A and 27 in group B. The mean coronal deviations were 1.16 and 1.11 mm (P = 0.35), respectively; the mean apical deviations were 1.65 and 1.71 mm (P = 0.22); the mean depth deviations were 0.95 and −0.68 mm (P = 0.032); the mean buccolingual angular deviations were 4.16° and 6.72° (P = 0.042); and the mean mesiodistal ones were 2.81° and 5.61° (P = 0.029). In addition, the accuracy was statistically influenced only by implant diameter for coronal discrepancy (P = 0.035) and by jaw of interest for mesiodistal angulation (P = 0.045). Conclusion. Fully guided implant surgery was more accurate than pilot-drill guided surgery for different parameters. For both types of surgery, a safety margin of at least 2mm should be preserved during implant planning to prevent damage to nearby anatomical structures

Extension of lymphadenectomy for gastric cancer:Audit at European specialist centres.

Gastric cancer is still one of the leading causes of cancer-related deaths worldwide, and its treatment management differs between Eastern Asia and Western countries. Screening program, early diagnosis, and surgical treatment was primarily established in Japan and was rapidly disseminated to other countries. In other parts of the world, such as the USA and Western Europe, the incidence of gastric cancer has declined, and efforts for screening and early detection have not been an issue of higher priority over the management of other diseases. Thus, gastric cancer in the West is often more advanced and is either inoperable or needs more radical surgery for resection. The only treatment method that can potentially cure gastric cancer is the surgical approach. Depending on the extension of the tumor, surgeons may execute an operation that involves removing all or part of the stomach with some nearby lymph nodes (lymphadenectomy). Lymphadenectomy is a crucial step during surgical operation that involves the removal of one or more lymph nodes located in the drainage area of a tumor, in which there is a high possibility of lymph node metastasis. The Japanese guidelines define the criteria of lymphadenectomy procedure into D1 D1+ or D2 according to the type of gastrectomy executed. The extent of lymphadenectomy has long been a subject of debate. Indeed, Japanese surgeons introduced extended lymphadenectomy (D2), which has also been progressively adopted in Europe and included in almost all international guidelines. However, the procedure requires a long learning curve, which involves a high volume of interventions; therefore, US guidelines do not recommend the D2, and many Italian and European centres do not yet perform this procedure. Indeed, the current European Consensus guidelines recommend D2 dissection in regional specialist centres for patients with moderate comorbidity. However, compliance with guidelines is unclear, and in some recent RCTs, the standard approach of surgical treatment is at the "surgeon's discretion." This study aims to evaluate the current practice of D2 lymphadenectomy in Europe to determine any variation in practice and compare it with the Japanese guidelines. The study consists of two parts: first, a questionnaire based on hypothetical clinical scenarios was administered to expert surgeons belonging to European Chapter of the International Gastric Cancer Association from high-volume European centers. They were asked to select the appropriate lymphadenectomy extension for each hypothetical case and the associated lymph node stations to remove. In the second part of the study, the same surgeons were asked to collect their data about gastric cancer gastrectomies performed in 2015 for comparative analysis. The study results show that the expert surgeons of high-volume centres are quite in agreement with the choice of D2 lymphadenectomy in the different clinical scenarios. The surgical choice seems to have been influenced by the tumor stage, site, and histology of the tumor. More specifically, the D2 procedure is recommended for cases with diffuse histology compared to tumors with intestinal histology. However, the selection of the D2 dissection procedure rarely conformed to Japanese guidelines: the choice of lymph node stations revealed the presence of a wide variation in execution. In the review of the gastrectomy experience, it was observed that a high surgical standard was achieved: in fact, in 97% of gastric cancer gastrectomies after D2, an adequate number of lymph nodes (≥15 nodes) were removed. In conclusion, even if an adequate lymphadenectomy was obtained in almost all cases in dedicated centers, there is still significant variability in the number of recovered lymph nodes. The histology of the tumor largely influences the surgeon's choice regarding the extent of the lymphadenectomy; however, the role of histology in the planning of surgical procedures is not considered in the current guidelines and must be verified in prospective studies

The Coexistence of asthma and Chronic Ostructive Pulmonary Disease (COPD): prevalence and risk factors in young, middle-aged and elderly people from the general population

Background: The joint distribution of asthma and chronic obstructive pulmonary disease (COPD) has not been well described. This study aims at determining the prevalence of self-reported physician diagnoses of asthma, COPD and of the asthma-COPD overlap syndrome and to assess whether these conditions share a common set of risk factors. Methods: A screening questionnaire on respiratory symptoms, diagnoses and risk factors was administered by mail or phone to random samples of the general Italian population aged 20–44 (n = 5163) 45–64 (n = 2167) and 65–84 (n = 1030) in the frame of the multicentre Gene Environment Interactions in Respiratory Diseases (GEIRD) study. Results: A physician diagnosis of asthma or COPD (emphysema/chronic bronchitis/COPD) was reported by 13% and 21% of subjects aged &lt;65 and 65–84 years respectively. Aging was associated with a marked decrease in the prevalence of diagnosed asthma (from 8.2% to 1.6%) and with a marked increase in the prevalence of diagnosed COPD (from 3.3% to 13.3%). The prevalence of the overlap of asthma and COPD was 1.6% (1.3%–2.0%), 2.1% (1.5%–2.8%) and 4.5% (3.2%–5.9%) in the 20–44, 45–64 and 65–84 age groups. Subjects with both asthma and COPD diagnoses were more likely to have respiratory symptoms, physical impairment, and to report hospital admissions compared to asthma or COPD alone (p&lt;0.01). Age, sex, education and smoking showed different and sometimes opposite associations with the three conditions. Conclusion: Asthma and COPD are common in the general population, and they coexist in a substantial proportion of subjects. The asthma-COPD overlap syndrome represents an important clinical phenotype that deserves more medical attention and further research.</br

Knowledge and use of e-cigarettes among nursing students: results from a cross-sectional survey in north-eastern Italy

Data on electronic cigarette (e-cigarette) use among health professional students, who can play a central role in promoting healthy habits and smoking cessation, are sparse. Moreover, the association between e-cigarettes and smoking habits is still debated. The present study aimed to investigate the diffusion of e-cigarette use among nursing students in north-eastern Italy and explore its association with tobacco smoking

ASRS Questionnaire and Tobacco Use: Not Just a Cigarette. A Screening Study in an Italian Young Adult Sample

Young adults exhibit greater sensitivity than adults to nicotine reinforcement, and Attention Deficit Hyperactivity Disorder (ADHD) increases the risk for early-onset smoking. We investigated the correlation between ADHD Self-Report Scale (ASRS) scores and smoking, evaluated the prevalence of ADHD symptomatology (not diagnoses) in smokers and non-smokers and its comorbidity with benzodiazepine and gambling addictions. A total of 389 young adults from 14 schools in Northern Italy fill out a survey and the Adult ADHD Self-Report Scale (ASRS). A total of 15.2% of subjects tested positive at the ASRS, which correlated with smoking; moreover, smokers had twice the probability of testing positive at the ASRS. ADHD symptomatology, especially when comorbid with tobacco abuse, is an important condition to monitor because early nicotine exposure could be a gateway for other addictive behaviors

Seventy years of asthma in Italy: age, period and cohort effects on incidence and remission of self-reported asthma from 1940 to 2010

Background: It is well known that asthma prevalence has been increasing all over the world in the last decades. However, few data are available on temporal trends of incidence and remission of asthma. Objective: To evaluate the rates of asthma incidence and remission in Italy from 1940 to 2010. Methods: The subjects were randomly sampled from the general Italian population between 1991 and 2010 in the three population-based multicentre studies: ECRHS, ISAYA, and GEIRD. Individual information on the history of asthma (age at onset, age at the last attack, use of drugs for asthma control, co-presence of hay-fever) was collected on 35,495 subjects aged 20–84 and born between 1925–1989. Temporal changes in rates of asthma incidence and remission in relation to age, birth cohort and calendar period (APC) were modelled using Poisson regression and APC models. Results: The average yearly rate of asthma incidence was 2.6/1000 (3,297 new cases among 1,263,885 person-years). The incidence rates have been linearly increasing, with a percentage increase of +3.9% (95%CI: 3.1–4.5), from 1940 up to the year 1995, when the rates begun to level off. The stabilization of asthma incidence was mainly due to a decrease in the rates of atopic asthma after 1995, while non-atopic asthma has continued to increase. The overall rate of remission was 43.2/1000person-years, and it did not vary significantly across generations, but was associated with atopy, age at asthma onset and duration of the disease. Conclusions: After 50 years of a continuous upward trend, the rates of asthma incidence underwent a substantial stabilization in the late 90s. Despite remarkable improvements in the treatment of asthma, the rate of remission did not change significantly in the last seventy years. Some caveats are required in interpreting our results, given that our estimates are based on self-reported events that could be affected by the recall bias

Health Surveillance and Response to SARS-CoV-2 Mass Testing in Health Workers of a Large Italian Hospital in Verona, Veneto

Italy presented the first largest COVID-19 outbreak outside of China. Veneto currently ranks fourth among the Italian regions for COVID-19 confirmed cases (~19,000). This study presents health surveillance data for SARS-CoV-2 in 6100 health workers (HW) employed in a large public hospital. Workers underwent oropharyngeal and nasopharyngeal swabs, with a total of 5942 participants (97.5% of the population). A total of 11,890 specimens were tested for SARS-CoV-2 infection using PCR, identifying the viral genes E, RdRP, and N. Positive tests were returned for 238 workers (cumulative incidence of 4.0%, similar in both COVID and nonCOVID units). SARS-CoV-2 risk was not affected by gender, age, or job type, whereas work setting and occupation were both predictors of infection. The risk was higher in medical wards (OR 2.7, 95% CI 1.9\u20133.9) and health services (OR 4.3, 95% CI 2.4\u20137.6), and lower in surgical wards and administration areas. To our knowledge, this study represents the largest available HW case list swab-tested for SARS-CoV-2, covering almost the total workforce. Mass screening enabled the isolation of HW, improved risk assessment, allowed for close contacts of and infected HW to return to work, provided evidence of SARS-CoV-2 diffusion, and presented solid ground to prevent nosocomial SARS-CoV-2 infections. The ongoing concurrent sero-epidemiological study aims to enable the improvement of health surveillance to maintain the safety of HWs and the communities they serve
