An international delphi survey and consensus meeting to define the risk factors for ureteral stricture after endoscopic treatment for urolithiasis.

PURPOSE: Iatrogenic ureteral strictures (US) after endoscopic treatment for urolithiasis represent a significant healthcare concern. However, high-quality evidence on the risk factors associated with US is currently lacking. We aimed to develop a consensus statement addressing the definition, risk factors, and follow-up management of iatrogenic US after endoscopic treatment for urolithiasis. METHODS: Utilizing a modified Delphi method, a steering committee developed survey statements based on a systematic literature review. Then, a two-round online survey was submitted to 25 experts, offering voting options to assess agreement levels. A consensus panel meeting was held for unresolved statements. The predetermined consensus threshold was set at 70%. RESULTS: The steering committee formulated 73 statements. In the initial survey, consensus was reached on 56 (77%) statements. Following in-depth discussions and refinement of 17 (23%) statements in a consensus meeting, the second survey achieved consensus on 63 (86%) statements. This process underscored agreement on pivotal factors influencing US in endoscopic urolithiasis treatments. CONCLUSIONS: This study provides a comprehensive list of categorized risk factors for US following endoscopic urolithiasis treatments. The objectives include enhancing uniformity in research, minimizing redundancy in outcome assessments, and effectively addressing risk factors associated with US. These findings are crucial for designing future clinical trials and guiding endoscopic surgeons in mitigating the risk of US.

Consensus statement addressing controversies and guidelines on pediatric urolithiasis.

PURPOSE: We aimed to investigate controversial pediatric urolithiasis issues systematically, integrating expert consensus and comprehensive guidelines reviews. METHODS: Two semi-structured online focus group meetings were conducted to discuss the study's need and content, review current literature, and prepare the initial survey. Data were collected through surveys and focus group discussions. Existing guidelines were reviewed, and a second survey was conducted using the Delphi method to validate findings and facilitate consensus. The primary outcome measures investigated controversial issues, integrating expert consensus and guideline reviews. RESULTS: Experts from 15 countries participated, including 20 with 16+ years of experience, 2 with 11-15 years, and 4 with 6-10 years. The initial survey identified nine main themes, emphasizing the need for standardized diagnostic and treatment protocols and tailored treatments. Inter-rater reliability was high, with controversies in treatment approaches (score 4.6, 92% agreement), follow-up protocols (score 4.8, 100% agreement), and diagnostic criteria (score 4.6, 92% agreement). The second survey underscored the critical need for consensus on identification, diagnostic criteria (score 4.6, 92% agreement), and standardized follow-up protocols (score 4.8, 100% agreement). CONCLUSION: The importance of personalized treatment in pediatric urolithiasis is clear. Prioritizing low-radiation diagnostic tools, effectively managing residual stone fragments, and standardized follow-up protocols are crucial for improving patient outcomes. Integrating new technologies while ensuring safety and reliability is also essential. Harmonizing guidelines across regions can provide consistent and effective management. Future efforts should focus on collaborative research, specialized training, and the integration of new technologies in treatment protocols.

Ureteral stricture rate after endoscopic treatments for urolithiasis and related risk factors: systematic review and meta-analysis.

PURPOSE: We aimed to accurately determine ureteral stricture (US) rates following urolithiasis treatments and their related risk factors. METHODS: We conducted a systematic review and meta-analysis following the PRISMA guidelines using databases from inception to November 2023. Studies were deemed eligible for analysis if they included ≥ 18 years old patients with urinary lithiasis (Patients) who were subjected to endoscopic treatment (Intervention) with ureteroscopy (URS), percutaneous nephrolithotomy (PCNL), or shock wave lithotripsy (SWL) (Comparator) to assess the incidence of US (Outcome) in prospective and retrospective studies (Study design). RESULTS: A total of 43 studies were included. The pooled US rate was 1.3% post-SWL and 2.1% post-PCNL. The pooled rate of US post-URS was 1.9% but raised to 2.7% considering the last five years' studies and 4.9% if the stone was impacted. Moreover, the pooled US rate differed if follow-ups were under or over six months. Patients with proximal ureteral stone, preoperative hydronephrosis, intraoperative ureteral perforation, and impacted stones showed higher US risk post-endoscopic intervention with odds ratio of 1.6 (P = 0.05), 2.6 (P = 0.009), 7.1 (P < 0.001), and 7.47 (P = 0.003), respectively. CONCLUSIONS: The overall US rate ranges from 0.3 to 4.9%, with an increasing trend in the last few years. It is influenced by type of treatment, stone location and impaction, preoperative hydronephrosis and intraoperative perforation. Future standardized reporting and prospective and more extended follow-up studies might contribute to a better understanding of US risks related to calculi treatment.

Trends in thyroid function testing, neck ultrasound, thyroid fine needle aspiration, and thyroidectomies in North-eastern Italy.

PURPOSE: Evidence of an increased diagnostic pressure on thyroid has emerged over the past decades. This study aimed to provide estimates of a wide spectrum of surveillance indicators for thyroid dysfunctions and diseases in Italy. METHODS: A population-based study was conducted in North-eastern Italy, including 11.7 million residents (20% of the total Italian population). Prescriptions for TSH testing, neck ultrasound or thyroid fine needle aspiration (FNA), surgical procedures, and drugs for hypo- or hyperthyroidism were extracted from regional health databases. Proportions and rates of selected examinations were calculated from 2010 to 2017, overall and by sex, calendar years, age, and region. RESULTS: Between 2010 and 2017 in North-eastern Italy, 24.5% of women and 9.8% of men received at least one TSH test yearly. In 2017, 7.1% of women and 1.5% of men were prescribed drugs for thyroid dysfunction, 94.6% of whom for hypothyroidism. Neck ultrasound examinations were performed yearly in 6.9% of women and 4.6% of men, with a nearly two-fold variation between areas. Thyroid FNA and thyroidectomies were three-fold more frequent in women (394 and 85 per 100,000) than in men (128 and 29 per 100,000) with a marked variation between areas. Both procedures decreased consistently after 2013. CONCLUSIONS: The results of this population-based study describe recent variations over time and between surrounding areas of indicators of 'diagnostic pressure' on thyroid in North-eastern Italy. These results emphasize the need to harmonize practices and to reduce some procedures (e.g., neck ultrasound and total thyroidectomies) in certain areas.

Socioeconomic status and skin cancer incidence: a population-based, cohort study in the province of Ferrara, northern Italy.

To assess the impact of socioeconomic status (SES) on the occurrence of skin cancer in the population living in the province of Ferrara, Italy, a retrospective cohort of patients with squamous cell carcinoma (SCC), basal cell carcinoma (BCC) or malignant melanoma (MM), provided by the local cancer registry, was investigated. The SES was expressed through an ecological-based deprivation index. During the 8-year study period (2006-2013, total person-years 2 859 137), 6051 carcinomas (1535 SCCs, 4365 BCCs) and 459 MMs were diagnosed. Both crude and standardized (on the European population) rates and the standardized incidence ratio showed a direct correlation between BCC and SES. Multivariate analysis confirmed these results for BCC and also for MM, while it showed an excess of SCC incidence in the lowest SES subgroup. This study shows, for the first time, to our knowledge, opposite effects of SES on SCC and BCC occurrence. A role of environmental factors conditioned by SES may be hypothesized.

The burden of HPV-related diseases in Italy, 2001-12.

Background: Human papillomavirus (HPV) infection is the main cause of cervical cancer and plays a relevant role in the development of genital warts and of the cancer of penis and anus, head/neck, oropharynx and genitourinary system. The aim of this study is the evaluation of hospitalizations due to HPV-related pathologies in 2001-12 in Italy. Methods: The national hospital discharge forms were provided by the Ministry of Health. The HPV-related hospitalizations were identified using specific diagnostic codes, accordingly to the ICD-9-CM coding system. The proportion of hospitalizations of potentially HPV-related pathologies, obtained from the literature, was evaluated as well as the hospitalization rates (hr) and their trend over time. Results: Uterine cervical cancer and CIN III accounted for 40% of hospitalizations (hr: 15.6/100 000 and 17.6/100 000, respectively). Head/neck and oropharynx pathologies accounted for 24.5% of cases (hr: 16/100 000 and 3.9/100 000, in males and females, respectively), followed by genital warts (17.3% of hospitalizations; hr: 7.5/100 000 in males and 8.52/100 000 in females), anal (8.1% of hospitalizations), genitourinary (7.7%) and penis cancers (2.2%). Conclusions: The study, even if limited to the evaluation of hospitalizations, points out how HPV-related pathologies continue to be a relevant public health issue in Italy with a high impact on population.

Long-term survival, prevalence, and cure of cancer: a population-based estimation for 818 902 Italian patients and 26 cancer types.

BACKGROUND: Persons living after a cancer diagnosis represent 4% of the whole population in high-income countries. The aim of the study was to provide estimates of indicators of long-term survival and cure for 26 cancer types, presently lacking. PATIENTS AND METHODS: Data on 818 902 Italian cancer patients diagnosed at age 15-74 years in 1985-2005 were included. Proportions of patients with the same death rates of the general population (cure fractions) and those of prevalent patients who were not at risk of dying as a result of cancer (cure prevalence) were calculated, using validated mixture cure models, by cancer type, sex, and age group. We also estimated complete prevalence, conditional relative survival (CRS), time to reach 5- and 10-year CRS >95%, and proportion of patients living longer than those thresholds. RESULTS: The cure fractions ranged from >90% for patients aged <45 years with thyroid and testis cancers to <10% for liver and pancreatic cancers of all ages. Five- or 10-year CRS >95% were both reached in <10 years by patients with cancers of the stomach, colon-rectum, pancreas, corpus and cervix uteri, brain, and Hodgkin lymphoma. For breast cancer patients, 5- and 10-year CRSs reached >95% after 19 and 25 years, respectively, and in 15 and 18 years for prostate cancer patients. Five-year CRS remained <95% for >25 years after cancer diagnosis in patients with liver and larynx cancers, non-Hodgkin lymphoma, myeloma, and leukaemia. Overall, the cure prevalence was 67% for men and 77% for women. Therefore, 21% of male and 31% of female patients had already reached 5-year CRS >95%, whereas 18% and 25% had reached 10-year CRS >95%. CONCLUSIONS: A quarter of Italian cancer patients can be considered cured. This observation has a high potential impact on health planning, clinical practice, and patients' perspective.

Laparoscopic adrenalectomy for large adrenal masses: a challenge or a routine?

AIM: The increased incidence of malignancy and the concern for higher rate of complications with laparoscopic resection of larger tumors typically limits laparoscopic adrenalectomy to small adrenal masses. We used our prospectively collected database to compare laparoscopic adrenalectomy outcomes between small and large adrenal tumors. METHODS: Operative details and outcomes were compared by adrenal mass size size: Group A≤4 cm and Group B>4 cm, for consecutive laparoscopic adrenalectomies performed between 2009 and 2013. RESULTS: Group A (N.=50) and Group B (N.=27) subjects had similar operative times (131 vs. 132 min, P=0.48). Group B subjects were older, had more adrenal malignancies, and had a higher blood loss with a slightly larger change in hemoglobin than Group A subjects; however, no subject required blood transfusion and complication rates were similar between groups (4% vs. 11%, P=0.34). One subject from each group required conversion to open adrenalectomy. CONCLUSION: Laparoscopic adrenalectomy can be performed safely for adrenal masses >4 cm and size is not a contraindication to the laparoscopic approach.

Intranasal human-recombinant nerve growth factor administration improves cognitive functions in a child with severe traumatic brain injury.

BACKGROUND: Behavioral and neuropsychological functions are frequent long-term sequelae of severe traumatic brain injury (TBI). Neuropeptides, such as nerve growth factor (NGF), can enhance neurogenesis and improve cognitive functions after TBI, playing a pivotal role in neuroplasticity. A limited number of studies documented the safety and efficacy of intranasal NGF administration in children with severe TBI. CASE REPORT: A fourteen-year-old boy with a diffuse axonal injury secondary to severe TBI was treated with human-recombinant NGF administration. This patient underwent treatment with intranasal hr-NGF administration at a total dose of 50 gamma/kg, three times a day for seven consecutive days. The treatment schedule was performed for 4 cycles, at one month distance each. NGF administration improved radiologic functional assessment evaluated with positron emission tomography scan (PET) and single photon emission computed tomography (SPECT), with an important improvement in clinical conditions. Significant improvements were also observed, mainly in cognitive processes, memory, the planning of a communication strategy, execution skills, attention, and verbal expression. No side effects were reported. CONCLUSIONS: Additional studies are required to gain a deeper insight into this neurotrophin's neuroprotective function, but our findings reveal a potential efficacy of intranasal hr-NGF administration in enhancing cognitive and clinical outcomes among children with diffuse axonal injury after severe TBI.

Patients with cancer who will be cured and projections of complete prevalence in Italy from 2018 to 2030.

BACKGROUND: The number and projections of cancer survivors are necessary to meet the healthcare needs of patients, while data on cure prevalence, that is, the percentage of patients who will not die of cancer by time since diagnosis, are lacking. MATERIALS AND METHODS: Data from Italian cancer registries (duration of registration ranged from 9 to 40 years, with a median of 22 years) covering 47% of the population were used to calculate the limited-duration prevalence, the complete prevalence in 2018, projections to 2030, and cure prevalence, by cancer type, sex, age, and time since diagnosis. RESULTS: A total of 3 347 809 people were alive in Italy in 2018 after a cancer diagnosis, corresponding to 5.6% of the resident population. They will increase by 1.5% per year to 4 012 376 in 2030, corresponding to 6.9% of the resident population, 7.6% of women and ∼22% after age 75 years. In 2030, more than one-half of all prevalent cases (2 million) will have been diagnosed by ≥10 years. Those with breast (1.05 million), prostate (0.56 million), or colorectal cancers (0.47 million) will be 52% of all prevalent patients. Cure prevalence was 86% for all patients alive in 2018 (87% for patients with breast cancer and 99% for patients with thyroid or testicular cancer), increasing with time since diagnosis to 93% for patients alive after 5 years and 96% after 10 years. Among patients who survived at least 5 years, the excess risk of death (1 - cure prevalence) was <5% for patients with most cancer types except for those with cancers of the breast (8.3%), lung (11.1%), kidney (13.2%), and bladder (15.5%). CONCLUSIONS: Study findings encourage the implementation of evidence-based policies aimed at improving long-term clinical follow-up and rehabilitation of people living after cancer diagnosis throughout the course of the disease. Updated estimates of complete prevalence are important to enhance data-driven cancer control planning.

Ascertainment bias in dementias: a secondary to tertiary centre analysis in Central Italy and conceptual review.

BACKGROUND AND AIMS: Ascertainment bias (AB) indicates a bias of an evaluation centre in estimating the prevalence/incidence of a disease due to the specific expertise of the centre. The aim of our study was to evaluate classification of different types of dementia in new cases appearing in secondary and tertiary centres, in order to evidence possible occurrence of AB in the various (secondary to tertiary) dementia centres. METHODS: To assess the mechanism of AB, the rates of new cases of the different forms of dementia reported by different centres were compared. The centres involved in the study were 11 hospital-based centres including a tertiary centre, located in the University Department of Clinical Neurology. The tertiary centre is endowed with state-of-the-art diagnostic facilities and its scientific production is prominently focused on dementia with Lewy bodies (DLB) thus suggesting the possible occurrence of a bias. Four main categories of dementia were identified: Alzheimer's disease (AD), DLB, fronto-temporal dementia (FTD), vascular dementia (VaD), with other forms in a category apart. The classification rate of new cases of dementia in the tertiary centre was compared with rates reported by secondary centres and rates of recoding were calculated during a follow-up of 2 years. RESULTS: The study classified 2,042 newly diagnosed cases of dementia in a population of 1,370,000 inhabitants of which 315,000 were older than 65. AD was categorized in 48-52 % of cases, DLB in 25-28 %, FTD in 2-4 % and VaD in 17-28 %. During the 2-year follow-up the diagnosis was re-classified in 40 patients (3 %). The rate of recoding was 5 % in the tertiary centre, 2-8 % in referrals from secondary to tertiary centre, 2-10 % in recodings performed in secondary centres and addressed to tertiary centre. Recoding or percentages of new cases of AD or DLB were not different in the comparison between secondary or between secondary and tertiary centres. FTD and VaD were instead significantly recoded. CONCLUSION: The results of the study suggest that in a homogeneous area, AB is not interfering with diagnosis of AD or DLB.

Single-center, prospective, and observational study on the management and treatment of impetigo in a pediatric population.

OBJECTIVE: Ozenoxacin is a new antibiotic used to treat non-bullous impetigo. The aim of this study is to evaluate the microbiological and clinical efficacy of topical ozenoxacin 1% cream after 5-day twice-daily treatment, in pediatric patients with impetigo. PATIENTS AND METHODS: This observational and prospective study included patients aged 6 months to 18 years, with non-bullous impetigo. Efficacy was measured using the Skin Infection Rating Scale (SIRS) and microbiological culture at the first visit (T0), at the second visit after 72 hours (T1) and after 5 days (T2). Safety and tolerability were also evaluated. RESULTS: A total of 50 patients was enrolled. A reduction of SIRS score >10% after 72 hours of treatment was noticed in all patients, while a complete reduction was assessed after 5 days in all the population. Microbiologic success rates for ozenoxacin at T1 was 92% (four patients had original pathogens in the specimen culture from the skin area), whereas at T2, it was 100%. CONCLUSIONS: Topical ozenoxacin has strong efficacy in treating impetigo in pediatric patients. Ozenoxacin's clinical and microbiological rapid onset of response led to consider this antibiotic a novel efficacy option for the treatment of impetigo.

The HIV paradox: Perinatal mortality is lower in HIV-positive mothers-A field case-control study in Ethiopia.

OBJECTIVE: Sub-Saharan African countries have the highest perinatal mortality rates. Although HIV is a risk factor for perinatal death, antioretroviral therapy (ART) programs have been associated with better outcomes. We aimed to investigate how maternal HIV affects perinatal mortality. METHODS: The authors performed a nested case-control study at Saint Luke Hospital, Wolisso, Ethiopia. Data on sociodemographic characteristics, current maternal conditions, obstetric history, and antenatal care (ANC) services utilization were collected. The association between perinatal mortality and HIV was assessed with logistic regression adjusting for potential confounders. RESULTS: A total of 3525 birthing women were enrolled, including 1175 cases and 2350 controls. Perinatal mortality was lower among HIV-positive women (18.3% vs. 33.6%, P = 0.007). Crude analysis showed a protective effect of HIV (odds ratio, 0.442 [95% confidence interval, 0.241-0.810]), which remained after adjustment (adjusted odds ratio, 0.483 [95% confidence interval, 0.246-0.947]). Among HIV-negative women, access to ANC for women from rural areas was almost half (18.8% vs. 36.2%; P < 0.001), whereas in HIV-positive women, no differences were noted (P = 0.795). CONCLUSION: Among HIV-positive mothers, perinatal mortality was halved and differences in access to ANC services by area were eliminated. These data highlight the benefits of integrating ANC and HIV services in promoting access to the health care system, reducing inequalities and improving neonatal mortality.

Asymptomatic bacteriuria in candidates for active treatment of renal stones: results from an international multicentric study on more than 2600 patients.

The occurrence of asymptomatic bacteriuria concomitant to urolithiasis is an issue for patients undergoing renal stone treatment. Disposing of a preoperative urine culture is essential to reduce the risk of septic events. The endpoint of the study is to report which characteristics of candidates for renal stone treatment are frequently associated with positive urine culture. 2605 patients were retrospectively enrolled from 14 centers; inclusion criteria were age > 18 and presence of a single renal stone 1-2 cm in size. The variables collected included age, gender, previous renal surgery, comorbidities, skin-to-stone distance, stone size, location, density, presence of hydronephrosis. After a descriptive analysis, the association between continuous and categorical variables and the presence of positive urine culture was assessed using a logistic regression model. Overall, 240/2605 patients (9%) had preoperative bacteriuria. Positive urine culture was more frequent in females, patients with previous renal interventions, chronic kidney disease, congenital anomalies, larger stones, increased density. Multivariate analysis demonstrated that previous renal interventions (OR 2.6; 95% CI 1.9-3.4; p < 0.001), renal-related comorbidities (OR 1.31; 95% CI 1.19-1.4; p < 0.001), higher stone size (OR 1.06; 95% CI 1.02-1.1; p = 0.01) and density (OR 1.00; 95% CI 1.0-1.00; p = 0.02) were associated with bacteriuria; male gender and lower caliceal location were inversely related to it. Beyond expected risk factors, such as female gender, other parameters are seemingly favoring the presence of positive urine culture. The awareness of variables associated with bacteriuria allows to assess which individuals are at increased risk of presenting bacteriuria and reduce the rate of septic complications.

Incidence of thyroid cancer in Italy, 1991-2005: time trends and age-period-cohort effects.

BACKGROUND: In Italy, some of the highest incidence rates (IRs) of thyroid cancer (TC) worldwide have been reported. PATIENTS AND METHODS: TC cases <85 years of age reported to Italian cancer registries during 1991-2005 were included. Age-standardized IRs were computed for all TC and age-period-cohort effects were estimated for papillary TC. RESULTS: IRs of TC were twofold higher in 2001-2005 than in 1991-1995 (18 and 8 per 100,000 women, 6 and 3 per 100,000 men, respectively). Increases were similar in the two sexes and nearly exclusively due to papillary TC. Increases of papillary TC by birth cohort were found in both sexes and among all age groups between 20 and 79 years. Age-period-cohort models showed a strong period effect in both sexes (rate ratio for 2001-2009 versus 1991-1995 = 2.5 in women and 2.3 in men), although IRs peaked at an earlier age in women (45-49 years) than men (65-69 years). CONCLUSION: The strength of the period effect in both sexes and the earlier onset in women than men strongly implicated increased medical surveillance in the upward trends of papillary TC incidence in Italy. The consequences of the current intense search for TC on morbidity and possible overtreatment, especially among young women, should be carefully evaluated.

[Scientific collaboration between Istituto Superiore di Sanità and Italian Association of Cancer Registries for the study of cancer incidence in Italian polluted sites]. / Collaborazione scientifica ISS-AIRTUM per lo studio dell'incidenza dei tumori nei siti di interesse nazionale per le bonifiche.

The collaborative study between Istituto superiore di sanità and Associazione italiana registri tumori (ISS-AIRTUM) aims at investigating cancer incidence in polluted sites for adults and for children (0-14 years) and adolescents (15-19 years) to comment the study results in the light of a set of a priori hypotheses. On the whole, 141 out of 298 municipalities included in SENTIERI Project are served by a Cancer Register participating to the AIRTUM network. For a description of SENTIERI, refer to the 2010 Supplement of Epidemiology & Prevention devoted to SENTIERI Project. The time window of the study is the period 1996-2005. The number of expected cases in each polluted site will be estimated by applying incidence rates of the national pool of cancer registries and of the pool of the geographic macroarea in which each site is located: Northern, Central, Southern Italy and Islands. Cancer incidence in children and adolescents is one of the main priorities of international public health institutions, because of the need to protect childhood health from involuntary exposure to environmental risk factors. Standardized incidence ratios (SIRs) will be computed using expected figures derived from the national pool of cancer registries.

Early spontaneous pneumothorax, pneumomediastinum and pneumorrhachis in an adolescent with SARS-CoV-2 infection.

We report a case of spontaneous pneumomediastinum, pneumothorax, emphysema subcutaneous and pneumorrhachis, occurring in an adolescent resulting positive to SARS-CoV-2 nasopharyngeal swab. At the admission in Emergency Department, the child presented with left cervical and sternal pain, without respiratory symptoms. Radiological studies showed sizeable pneumomediastinum, bilateral apical pneumothorax, massive emphysema subcutaneous and pneumorrhachis. Patients' clinical conditions stood stable during the monitoring and he only needed conservative management. To our knowledge, this is the first description of spontaneous pneumomediastinum, pneumothorax, emphysema subcutaneous and pneumorrhachis, in a COVID-19 adolescent without concomitant pneumonia.
