Eligibility for competitive sport medical certification of children with severe hemophilia: Italian observational study.

Background ad aim of workː the position of Italian law regarding participation of prophylactically treated hemophiliacs to organized sport trainings and competitions remains unclear and this study focuses on the eligibility of pediatric patients in particular. Methodsː 16 patients age 3 to 15 years old, with severe haemophilia and prophylaxis starting age of 20,2 ± 2,2 months were enrolled. Weight, height, body mass index (BMI) and joint status (Hemophilia Joint Health Score [HJHS] and Haemophilia Early Arthropathy Detection with UltraSound, HEAD-US score) of patients were evaluated at start (T0) and after 12 months (T12) of a HIITS sport activity program. Resultsː All patients qualified for Italian competitive sport medical certification. Their weight and height increased after 12 months, without an increase in BMI (T0= 17,2; T1= 18,7; p>0,05). HJHS score did not change significantly (T0: 1.6 ± 1; T1: 2.1 ± 1.3; p>0.05). All children were right-handed and atrophy for the muscles of the right elbow significantly decreased (no atrophy seen at T0 in 4 of 16 patients and at T1 in 8 of 16 patients; p=0.045). Conclusionsː Hemophilic children, prophylactically treated, are capable to be included in sport groups and physical activity programs.

Athermal versus ultrasonic nerve-sparing laparoscopic radical prostatectomy: a comparison of functional and oncological outcomes.

PURPOSE: Many urologists emphasize the concept of heat-related damage suggesting the avoidance of any energy to perform nerve-sparing radical prostatectomy. At our institution, both athermal and ultrasonic dissection have been used over the last years to perform a nerve-sparing laparoscopic radical prostatectomy (NSLRP). In this study, we compare functional and oncological outcomes of the two procedures. METHODS: All charts from patients undergoing NSLRP between January 2009 and June 2015 were reviewed. The International Index of Erectile Function (IIEF-5) was recorded preoperatively and 3, 12 and 24 months after surgery; continence was recorded at 3 and 12 months; PSA was recorded at last follow-up. Uni- and multivariate analyses were performed to assess the association of variables with functional and oncological outcomes. RESULTS: Ultrasonic NSLRP was used for 120 patients, while athermal NSLRP on 111. The impact of the cutting technique on erection recovery was different at 3 months, favoring athermal dissection (p = 0.002); however, significance was lost at 12 (p = 0.09) and 24 (p = 0.14) months. Continence recovery was comparable at 3 (p = 0.1) and 12 (p = 0.2) months; the rate of positive surgical margins and PSA recurrence were also similar (p = 0.2 and p = 0.06, respectively). At univariate analysis, age, Gleason sum, nerve-sparing laterality, and extension (intra- vs interfascial) were associated with overall erection recovery; only age and nerve-sparing laterality were independent predictors. Age and preoperative TRUS prostate volume were associated with continence recovery, both at uni- and multivariate analysis. CONCLUSIONS: The use of an ultrasonic device compared to athermal dissection during NSLRP does not affect long-term potency, nor continence and early biochemical recurrence.

Serum Vitamin D Levels in Children with Immune Thrombocytopenia.

OBJECTIVE: Immune thrombocytopenia (ITP) is an acquired immuno-mediated disorder characterized by thrombocytopenia with an increased risk of bleeding. In recent years 1,25[OH]2D3 has been rediscovered as an immune modulator. We decided to evaluate serum Vitamin D levels in a cohort of children with immune thrombocytopenia in order to discover if Vitamin D concentrations may predict ITP duration. METHODS: Thirty children were enrolled in this study (sixteen with chronic ITP and fourteen with newly diagnosed ITP) to assess serum Vitamin D levels. RESULTS: The results showed that 80% of the enrolled children presented a D hypovitaminosis status. Children with newly diagnosis ITP showed no statistically significantly higher median values of Vitamin D compared to chronic ITP. CONCLUSION: This study may suggest that Vitamin D deficiency does not represent a chronicity factor for ITP. However, further studies are needed to understand the role of Vitamin D in ITP pathogenesis.

Medical students' attitude toward influenza vaccination: Results of a survey in the University of Bari (Italy).

Influenza vaccination is strongly recommended for Italian healthcare professionals, but vaccine coverage is low. Since 2012, vaccination is also offered to medical students as part of the National Immunization Plan; however, few Medical Schools has implemented the plan so far. To study determinants of vaccination compliance, we conducted a survey among medical students at the University of Bari, where influenza vaccination has been actively offered since 2013. Information was obtained by means of an online anonymous questionnaire administered in April 2014. We enrolled 669 students, 383 (57%) vaccinated; 54% were female and the average age was 23.9 ± 4.9 y. Determinants of getting vaccinated were analyzed in a multivariate logistic model. Receiving invitation from the University (aOR = 3.8; 95%CI = 1.2-12.3; p = 0.026), the opinion that vaccine is safe (aOR = 2.8; 95%CI = 1.5-5.0; p = 0.001) and useful (aOR = 3.4; 95%CI = 1.7-6.7; p<0.0001), a specific training about influenza vaccination during the course (aOR = 1.5; 95%CI = 1.1-2.1; p = 0.043), and considering himself as at a major risk of influenza complication (aOR = 1.8; 95% CI = 1.1-2.9; p = 0.001) were significantly associated with vaccine acceptance. Active invitation and training are confirmed as key actions (as in children vaccination strategies) and, according to our results, they could be routinely used to promote vaccination in hard-to-reach groups such as healthcare workers.

Lack of immunity against rubella among Italian young adults.

BACKGROUND: To support the evaluation of the 2010-15 National Plan for Measles and Congenital Rubella Elimination, the authors designed and performed a serosurveillance survey to verify the immunity/susceptibility rate against rubella among Apulian young adults. METHODS: The study was carried out from May 2011 to June 2012 in the Department of Transfusion Medicine/Blood Bank of Policlinico General Hospital in Bari. Subjects were enrolled by a convenience sampling. For each enrolled patient a 5 ml serum sample was collected and tested for anti-rubella IgG. The geometrical means (GMT) of anti-rubella IgG was calculated. T student test or ANOVA test, when appropriate, was used to compare the means of age per gender and GMT of anti-rubella IgG titres per age classes. Chi-square test was used to compare the proportion of anti-rubella IgG positive subjects per gender and per age classes. For all tests, a p value <0.05 was considered as significant. RESULTS: At the end of the study 1764 subjects were enrolled, 1362 (77.2%) of which were male. The mean age was 38.4 ± 11.7 years (range: 17-65). 86.7% (95% CI = 85.0-88.2) had a positive titre of anti-rubella IgG. GMT of anti-rubella IgG titre was 4.3. The proportion of positive subjects was of 76.8% (n = 279/363; 95% CI = 72.2-81.1) in persons aged 18-26 years; 88.1% (n = 310/352; 95% CI = 84.2-91.3) in 27-35 year-old people; 88.5% (n = 464/524; 95% CI = 85.5-91.1) in 36-45 year-old people; 90.7% (n = 350/386; 95% CI = 87.3-93.4) among people aged 46-55 years and 90.6% (n = 126/139; 95% CI = 84.5-94.9) in 55-65 year-old people (Chi-square = 39.7; p < 0.0001). GMT of anti-rubella IgG titre was 4.3 (4.3 in male and 4.2 in female, t = 2.2; p = 0.03) and seems to differ dividing the enrolled subjects by age group (F = 14.3; p < 0.0001). CONCLUSIONS: According to our data, too many women of child-bearing age are still unprotected from rubella in the elimination era and in this scenario the public health efforts should be oriented to catch-up activities.

Serosurveillance of hepatitis A in a region which adopted the universal mass vaccination.

Hepatitis A is a common infectious disease worldwide that was endemic in many regions of Southern Italy, such as Apulia region. After a large hepatitis A outbreak occurred between 1996 and 1997, in Apulia an active-free immunization program that was targeted to new-borns and adolescents was started. The aim of this study is to investigate the hepatitis A seroprevalence in the adult Apulian population 18 years after the immunization program introduction, in order to evaluate the risk of new epidemics onset.The study was carried out from May 2011 to June 2012 among blood donors from Department of Transfusion Medicine and Blood Bank of Policlinico General Hospital in Bari. Participants signed a written consent and filled out a questionnaire including items on demographic characteristics, risk factors, disease memory, and raw food consumption. Serum samples, collected from each patient, were tested for anti-HAV using the chemiluminescent microparticle immunoassay. Vaccination status against hepatitis A was checked on Regional Digital Immunization Registry (GIAVA).In total 1827 donors agreed to participate (77.7% male) with a mean age of 38.4 ±â€Š11.7 years. However, 1172 (64.1%) donors were seropositive with no difference by sex. The highest proportion of seronegative subjects was in the 27 to 35 years age group. 91.8% of 1-dose vaccinated subjects (n = 190/207; 95%CI = 87.2-95.1) and 96.1% (n = 171/178; 95%CI = 92.1-98.1) of 2-doses vaccinated subjects were immune to the disease. Sensitivity of disease memory in unvaccinated subjects was 14.4% (95%CI = 12.2-16.7), specificity was 97.8% (95%CI = 96.3-98.8), positive predictive value was 91% (95%CI = 85.3-95), and negative predictive value was 42.6% (95%CI = 40-45.2). Raw seafood consumption in unvaccinated subjects was associated with the anti-HAV IgG positivity (OR = 2.1; 95%CI = 1.7-2.7; z = 7.4; P < 0.0001).The vaccination program seems to have changed the virus circulation pattern, with a higher seronegativity rate among subjects not included in the vaccination strategy: 67% of susceptible subjects were among younger people aged 27 to 35 years. Immunization program implementation with a catch-up strategy may be needed to avoid a possible increase of hepatitis A incidence and outbreaks in Apulia. Epidemiological surveillance should be continued and vaccination should actively be offer for free to all the cases contacts, in order to prevent new outbreaks onset.

Diagnostic Accuracy of Hexaminolevulinate in a Cohort of Patients Undergoing Radical Cystectomy.

PURPOSE: To compare the accuracy of white light cystoscopy (WLC) and blue light cystoscopy (BLC) in a cohort of patients undergoing radical cystectomy (RC) for previously resected urothelial bladder cancer. PATIENTS AND METHODS: A cohort of patients undergoing RC received WLC and BLC prior radical surgery. To evaluate the residual tumor rate, the bladder was inspected after its removal and normal appearing mucosa sampled for histologic analysis. Lesions detected under WLC, BLC, or both, and biopsy samples from normal appearing mucosa, were all recorded separately. RESULTS: Starting 2011, 64 patients underwent WLC and BLC prior cystectomy. Overall, 540 tissue samples were collected during cystoscopy and from normal appearing mucosa. Residual disease was found in 31/64 (48.4%) patients, including 27 (42.1%) cases of carcinoma in situ (CIS). The accuracy of BLC was much higher than WLC, both in the diagnosis of any residual disease (87.1% vs 32.3%, and 87.9% vs 51.5%, for sensitivity and specificity, respectively), as of CIS only (92.6% vs 29.6% and 83.8% vs 51.4%). We further evaluated the diagnostic accuracy as a result of the analysis on all specimens collected during the study. A total of 535 specimens were analyzed, and 58 specimens with residual disease were found, including 48 CIS foci. Again, detection rates and measures of accuracy were much better for BLC vs WLC, both overall (86.2% vs 31%, and 98.3% vs 93.3%, for sensitivity and specificity, respectively), and when CIS only was considered (89.6% vs 31.2% and 96.9% vs 92.8%). CONCLUSIONS: Although BLC missed 12.9% of positive patients, and 7.4% of those with CIS, the agreement between BLC diagnostic accuracy and the definitive pathology was very robust.

Evaluation of a vaccination strategy by serosurveillance data: The case of varicella.

Serological studies have many important epidemiologic applications. They can be used to investigate acquisition of various infections in different populations, measure the induction of an immune response in the host, evaluate the persistence of antibody, identify appropriate target groups and the age for vaccination. Serological studies can also be used to determine the vaccine efficacy. Since 1995 a varicella vaccine is available and it has been recommended in several countries (e.g. USA, Australia, Canada, Costa Rica, Ecuador, etc.). Nevertheless few varicella seroprevalence studies in countries that adopted an URV are available. It is related to the relatively recent introduction of the vaccination and to the lack of structured and collaborative surveillance systems based on serosurvey at national or regional level. Varicella seroprevalence data collected before the introduction of vaccination strategies allowed to establish the age of vaccination (e.g., indicated the opportunity to offer the vaccine to Italian susceptible adolescents). In the post-vaccination era, seroprevalence data demonstrated vaccine as immunogenic and excluded an increase of the age of infection linked to the vaccination strategy. New seroprevalence studies should be performed to answer to open questions, such as the long-term immunity and the change of the herpes zoster epidemiological pattern related to the vaccine.
