While pediatric biobanks are a precious resource for scientific research to improve our understanding of genetic pathologies, the value of these studies should be considered together with the value of the privacy rights of pediatric donors, as they are particularly vulnerable and in many cases unable to discern the meaning of the donation of biological material and the related implications of the research. Thus this work calls for reflection on the numerous ethical and legal issues involved in the development and regulation of these biobanks. In particular, it explores what form of consent best balances the intangible rights of the minor, on the one hand, and the development of technological progress and scientific research, on the other, and examines the implications of the collection of biological material of minors in biobanks. It focuses on solutions to bridge the gaps in current Italian legislation, especially in light of the current lack of attention to the interests of fragile subjects. In addition, this work presents an overview of the pediatric biobanks in Italy.

Objective This study aimed to evaluate the incidence of chronic groin pain (primary outcome) and alterations of sensitivity (secondary outcome) after Lichtenstein inguinal hernia repair, comparing neurectomy with ilioinguinal nerve preservation surgery. Summary background data The exact cause of chronic groin postoperative pain after mesh inguinal hernia repair is usually unclear. Section of the ilioinguinal nerve (neurectomy) may reduce postoperative chronic pain. Methods We followed PRISMA guidelines to identify randomized studies reporting comparative outcomes of neurectomy versus ilioinguinal nerve preservation surgery during Lichtenstein hernia repairs. Studies were identified by searching in PubMed, Scopus, and Web of Science from April 2020. The protocol for this systematic review and meta-analysis was submitted and accepted from PROSPERO: CRD420201610. Results In this systematic review and meta-analysis, 16 RCTs were included and 1550 patients were evaluated: 756 patients underwent neurectomy (neurectomy group) vs 794 patients underwent ilioinguinal nerve preservation surgery (nerve preservation group). All included studies analyzed Lichtenstein hernia repair. The majority of the new studies and data comes from a relatively narrow geographic region; other bias of this meta-analysis is the suitability of pooling data for many of these studies. A statistically significant percentage of patients with prosthetic inguinal hernia repair had reduced groin pain at 6 months after surgery at 8.94% (38/425) in the neurectomy group versus 25.11% (113/450) in the nerve preservation group [relative risk (RR) 0.39, 95% confidence interval (CI) 0.28–0.54; Z = 5.60 ( P  < 0.00001)]. Neurectomy did not significantly increase the groin paresthesia 6 months after surgery at 8.5% (30/353) in the neurectomy group versus 4.5% (17/373) in the nerve preservation group [RR 1.62, 95% CI 0.94–2.80; Z = 1.74 ( P  = 0.08)]. At 12 months after surgery, there is no advantage of neurectomy over chronic groin pain; no significant differences were found in the 12-month postoperative groin pain rate at 9% (9/100) in the neurectomy group versus 17.85% (20/112) in the inguinal nerve preservation group [RR 0.50, 95% CI 0.24–1.05; Z = 1.83 ( P  = 0.07)]. One study (115 patients) reported data about paresthesia at 12 months after surgery (7.27%, 4/55 in neurectomy group vs. 5%, 3/60 in nerve preservation group) and results were not significantly different between the two groups [RR 1.45, 95% CI 0.34, 6.21;Z = 0.51 ( P  = 0.61)]. The subgroup analysis of the studies that identified the IIN showed a significant reduction of the 6th month evaluation of pain in both groups and confirmed the same trend in favor of neurectomy reported in the previous overall analysis: statistically significant reduction of pain 6 months after surgery at 3.79% (6/158) in the neurectomy group versus 14.6% (26/178) in the nerve preservation group [RR 0.28, 95% CI 0.13–0.63; Z = 3.10 ( P  = 0.002)]. Conclusion Ilioinguinal nerve identification in Lichtenstein inguinal hernia repair is the fundamental step to reduce or avoid postoperative pain. Prophylactic ilioinguinal nerve neurectomy seems to offer some advantages concerning pain in the first 6th month postoperative period, although it might be possible that the small number of cases contributed to the insignificancy regarding paresthesia and hypoesthesia. Nowadays, prudent surgeons should discuss with patients and their families the uncertain benefits and the potential risks of neurectomy before performing the hernioplasty.

•In forensic age estimation there is growing interest in using MRI.•High-resolution MRI makes it possible to examine carpal microcomponents.•The development of carpal bones progresses through distinct stages.•A multiple linear regression model was used to estimate the individual’s age.•The ratio between the NO and SG of carpal bones is related to chronological age. Current multifactorial age estimation methods are based on radiography, however, in the forensic field there is growing interest in using magnetic resonance imaging (MRI). With regard to the carpal region, MRI provides more information for defining the individual ossification nuclei and the cartilage surrounding single bones. During the phase of bone growth, the progressive reduction of the cartilage layer is accompanied by the development of a cartilage-bone interface. The aim of our study was to create a new model for age estimation, based on the ratio between the area occupied by the nucleus of ossification (NO) and the surface of growth (SG) of each carpal bone, the latter derived by adding NO to the area of cartilage-bone interface. We analyzed 57 MRI scans of Italian subjects aged between 12 and 20 years, without growth diseases, endocrine disorders or osteodystrophy. Measurements of NO and SG areas were extracted using ImageJ software, and the ratio between the NO and SG of each bone (NOSG) was calculated. A multiple linear regression model was used to estimate the individual’s age as a function of the variables: gender and wrist bone measurements. The results showed that the best model was obtained with 6 predictors (nvmax=6): Gender, and the NOSG of the Trapezoid, Trapezium, Scaphoid, Pisiform, and Capitate. The median of the residuals (observed age minus predicted age) was −0.025 years, with an IQR of 0.19 years. Thus a new forensic approach to age assessment using MRI is introduced in this paper, which gives the preliminary results.

The most frequent sterilization procedures include postpartum tubal ligation, laparoscopic tubal disruption or salpingectomy, and hysteroscopic tubal occlusion. It may be performed via laparoscopy, mini-laparotomy, or hysteroscopy. Safety, efficacy, short-term complications, long-term complications, and non-contraceptive benefits of sterilization are different for each procedure. Female sterilization has become an important professional liability problem in obstetrics and gynecology. We analyzed 6 cases of surgical sterilization that have been the subject of civil proceedings. We review indications, contraindications, and complications associated with each sterilization procedure. In our small number of cases, women who have undergone sterilization performed negligently are entitled to recover damages for wrongful conception, negligence, and wrongful birth. We also consider the issue of female sterilization of minors. Tubal sterilization can be performed with different techniques, chosen in light of the various situations involved, with the goal of reducing as many as possible any failures. Thorough and complete communication of information is of primary importance. Sterilization is the most widely used birth control method around the world. The procedure is generally safe and highly effective. As reported in the literature, the decision concerning method depends on the setting, the surgeon's experience, the country's economic development, and the woman's preference, but we think that some techniques present a greater risk of failure and expose the surgeon to malpractice litigation.

In lung cancer patients infected with COVID-19, pathological features are not easy to distinguish. This report presents detailed histopathological findings in two non-neoplastic subjects whose out-of-hospital deaths were caused by COVID-19 infection. These ‘pure’ cases differ in the time of presentation of symptoms, the phase of lung anatomopathological patterns (acute lung injury versus diffuse alveolar damage) and the mechanism of death. The results provide a valid diagnostic benchmark for evaluating the evolution of COVID-19 pneumonia.

Background: Chronic postoperative inguinal pain [CPIP] is a prevalent and often debilitating complication following inguinal hernia repair. With the widespread adoption of mesh-based techniques, recurrence rates have significantly declined, shifting clinical focus toward postoperative pain management. Methods: This narrative review synthesizes international literature on CPIP incidence, surgical technique, geographic variation, and the distinction between neuropathic and nociceptive pain. Studies were selected based on relevance, sample size, and inclusion of pain subclassification. Results: CPIP incidence varies markedly across studies (6–64.3%), influenced by follow-up duration, surgical approach, and regional healthcare practices. The risk of CPIP varies significantly, depending on the surgical technique employed, with open repairs generally associated with higher rates than laparoscopic approaches. Neuropathic pain predominates in specific cohorts, particularly following open repairs with limited nerve preservation. Few studies differentiate pain types, revealing a critical gap in diagnostic precision. Conclusions: CPIP is a multifactorial and under-recognized problem in clinical practice. The adoption of standardized diagnostic tools and long-term follow-up protocols is essential to improve pain classification and management. A structured diagnostic algorithm may assist clinicians in distinguishing pain types and tailoring treatment strategies to individual patient profiles.

Sudden unexpected deaths often remain unresolved despite forensic examination, posing challenges for pathologists. Molecular autopsy, through genetic testing, can reveal hidden causes undetectable by standard methods. This review assesses the role of molecular autopsy in clarifying SUD cases, examining its methodology, utility, and effectiveness in autopsy practice. This systematic review followed PRISMA guidelines and was registered with PROSPERO (registration number: CRD42024499832). Searches on PubMed, Scopus, and Web of Science identified English studies (2018–2023) on molecular autopsy in sudden death cases. Data from selected studies were recorded and filtered based on inclusion/exclusion criteria. Descriptive statistics analyzed the study scope, tissue usage, publication countries, and journals. A total of 1759 publications from the past 5 years were found, with 30 duplicates excluded. After detailed consideration, 1645 publications were also excluded, leaving 84 full-text articles for selection. Out of these, 37 full-text articles were chosen for analysis. Different study types were analyzed. Mutations were identified in 17 studies, totaling 47 mutations. Molecular investigations are essential when standard exams fall short in determining sudden death causes. Expertise in molecular biology is crucial due to diverse genetic conditions. Discrepancies in post-mortem protocols affect the validity of results, making standardization necessary. Multidisciplinary approaches and the analysis of different tissue types are vital.

Since the beginning of the Covid-19 pandemic, many countries have begun vaccination campaigns, with different methods and timelines, with the goal of vaccinating over 75% of the population and thus achieving herd immunity. Initially it was necessary to identity the categories of citizens who should be the first to receive the vaccines, on the basis of scientific evidence. On the basis of this information, elderly residents in nursing homes and the staff who care for them should be the highest priority subjects for vaccination. In this context, obtaining informed consent to Covid-19 vaccination presents a considerable challenge, as the advanced age and frequent comorbidities of a significant number of the residents may mean that they are incapable of expressing consent themselves. The legislation of various Western nations substantially agrees on the general principle that those capable of judgement must be asked for their consent for healthcare services, and that even those with psychological weaknesses that limit their full ability to decide must be involved in these decision-making processes. The article can help systematize the processes to be implemented to protect the health of individuals as members of a close and fragile community.

In Italy, both parents have parental responsibility, so they have the power to give or withhold consent to medical procedures on their children. The present work reports the case of a 5-year-old boy diagnosed with neuroblastoma in the right adrenal loggia, who underwent several chemotherapy treatments that prolonged his life until the age of 10. Informed consent for treatments was requested exclusively of the parents, without taking into consideration the minor's will, not even when he asked for increased pain relief medication instead of other palliative treatments. The authors thought it interesting to examine the case in the light of new Italian legislation on informed consent and to verify whether it promotes greater participation of minors in healthcare choices, given that the issue of acquisition of informed consent is becoming increasingly broad and complex. The case examined here indicates that current Italian legislation, even including the modifications introduced, does not allow for concrete and active participation of minors, especially those under the age of 12, in the discussion of choices about their health, not even in choices regarding the end of life, and not even when the minor manifests a mature capacity for discernment.
