Abstract Pituitary tumours are surrounded by critical neurovascular structures and identification of these intra-operatively can be challenging. We have previously developed an AI model capable of sellar anatomy segmentation. This study aims to apply this model, and explore the impact of AI-assistance on clinician anatomy recognition. Participants were tasked with labelling the sella on six images, initially without assistance, then augmented by AI. Mean DICE scores and the proportion of annotations encompassing the centroid of the sella were calculated. Six medical students, six junior trainees, six intermediate trainees and six experts were recruited. There was an overall improvement in sella recognition from a DICE of score 70.7% without AI assistance to 77.5% with AI assistance (+6.7; p

Craniosacral rhythm is a manual therapy technique that focuses on the subtle, rhythmic movement of cerebrospinal fluid as it flows through the central nervous system and musculoskeletal system. Through light and delicate manipulation of the cranial bones, membranes and soft tissues of the head and neck, it promotes rebalancing and release from tension in the body, improving the circulation of the cerebrospinal fluid and the individual’s health. In the field of prosthetic dentistry, in rare cases, such as a full arch or removable partial denture, the patient perceives a sensation of constriction even though all procedures have been used correctly. In this work, a new design fora removable partial denture is proposed that does not interfere with the primary respiratory mechanism, reducing the sensation of constriction in the patient. The materials used are the same as those used for a normal removable partial denture, and the technique used is the “lost wax” one: the novelty is that the prosthesis is made in two separate parts that are joined by a central connection; the result is a removable partial denture with a small central thickening in the main joint represented by the connection of the two pieces. Craniosacral breathing movements are favored with this prosthesis as the metal structure is hyperstatic towards intrusion movements, more or less virtual in the opposite direction, i.e., extrusion towards the vestibule.

Glioblastoma is the most fatal and common malignant brain tumor, excluding metastasis and with a median survival of approximately one year. While solid tumors benefit from newly approved drugs, immunotherapy, and prevention, none of these scenarios are opening for glioblastoma. The key to unlocking the peculiar features of glioblastoma is observing its molecular and anatomical features tightly entangled with the host’s central nervous system (CNS). In June 2024, we searched the PUBMED electronic database. Data collection and analysis were conducted independently by two reviewers. Results: A total of 215 articles were identified, and 192 were excluded based on inclusion and exclusion criteria. The remaining 23 were used for collecting divergent molecular pathways and anatomical features of glioblastoma. The analysis of the selected papers revealed a multifaced tumor with extreme variability and cellular reprogramming that are observable within the same patient. All the variability of glioblastoma could be clustered into three pillars to dissect the physiology of the tumor: 1. necrotic core; 2. vascular proliferation; 3. CNS infiltration. These three pillars support glioblastoma survival, with a pivotal role of the neurovascular unit, as supported by the most recent paper published by experts in the field.

Background: Alzheimer’s disease is a slowly progressing neurodegenerative illness and the most common form of dementia. This pathology leads to an increase in cognitive decline and is responsible, in patients, for several difficulties in performing various activities of daily living, such as oral hygiene. Several experimental studies have shown that oral health in patients with Alzheimer’s disease worsens in direct proportion to the progression of the disease due to the appearance of gingivitis and periodontitis. Methods: This clinical literature review aims to evaluate a possible correlation between periodontal disease and Alzheimer’s disease, trying to understand if the periopathogens can contribute to the onset or the progression of Alzheimer’s disease (AD). The study was conducted on the database PubMed (MEDLINE) of full-text systematic reviews in English on humans and animals that were published in the last five years, from 2018 to 2023. This returned 50 publications, which, once the eligibility criteria were applied, resulted in the 10 publications examined in this review. The selected articles were organized through the construction of tables, analyzed, and compared through Judith Garrard’s Matrix method to arrive at the review results. Results: Infection by periopathogens can increase the risk of developing Alzheimer’s disease, but also the onset of the latter can make it more difficult to maintain proper oral hygiene, favoring the onset of periodontal disease: it is possible to affirm the existence of a correlation between periodontitis and AD. It was found that patients exposed to chronic periodontitis have a greater risk of developing a cognitive decline or AD and that oral pathogens can be responsible for neuropathologies and increasing systemic inflammation. Conclusions: Periodontitis and periodontal pathogens represent a real risk factor for the onset or worsening of AD; however, the pathogenetic mechanism is still not completely clear.

Amyotrophic lateral sclerosis (ALS) is the most frequent neurodegenerative disease of the motor system that affects upper and lower motor neurons, leading to progressive muscle weakness, spasticity, atrophy, and respiratory failure, with a life expectancy of 2–5 years after symptom onset. In addition to motor symptoms, patients with ALS have a multitude of nonmotor symptoms; in fact, it is currently considered a multisystem disease. The purpose of our narrative review is to evaluate the different types of pain, the correlation between pain and the disease’s stages, the pain assessment tools in ALS patients, and the available therapies focusing above all on the benefits of cannabis use. Pain is an underestimated and undertreated symptom that, in the last few years, has received more attention from research because it has a strong impact on the quality of life of these patients. The prevalence of pain is between 15% and 85% of ALS patients, and the studies on the type and intensity of pain are controversial. The absence of pain assessment tools validated in the ALS population and the dissimilar study designs influence the knowledge of ALS pain and consequently the pharmacological therapy. Several studies suggest that ALS is associated with changes in the endocannabinoid system, and the use of cannabis could slow the disease progression due to its neuroprotective action and act on pain, spasticity, cramps, sialorrhea, and depression. Our research has shown high patients’ satisfaction with the use of cannabis for the treatment of spasticity and related pain. However, especially due to the ethical problems and the lack of interest of pharmaceutical companies, further studies are needed to ensure the most appropriate care for ALS patients.

Abstract We report the case of an endovascular repair of an aortic arch aneurysm by a surgeon-modified fenestrated endograft with a single fenestration in a high-risk patient unfit for open surgery. A patient of 84 years, chronic ischemic cardiopathic, suffering from prostate adenocarcinoma in chemotherapy treatment, came to our hospital for post-traumatic fracture of the right femur. During the hospitalization, the patient exhibited dysphonia and respiratory disorders for several days, therefore, the patient performed Computed Tomography Angiography (CTA) that found the presence of voluminous aneurysm of the aortic arch with a maximum diameter of about 74 mm. The patient was treated with a hybrid-staged procedure; in the first instance, with a carotid-carotid-succlavium bypass to preserve the cerebral and upper limb vascularization and then, the procedure was completed by implanting the surgeon-modified fenestrated endograft with stent delivery to the patient with a fenestration on the anonymous trunk. This surgeon-modified fenestrated endograft was created by modifying a standard endograft by a single fenestration following the three-dimensional reconstructions of the CTA images. The procedure was successfully completed and postoperative course was uneventful. Computed Tomography Angiography demonstrated the exclusion of the aneurysm, patency of the implanted endograft modules, and absence of signs of endoleaks and / or cerebral or medullary ischemic complications.

Simple Summary: Biphenotypic sinonasal sarcoma is a rare low-grade tumor arising from the mucosa of the upper respiratory tract characterized by aggressive biological behavior and a high tendency to invade the skull base and the orbit. The main presenting symptoms and signs include nasal obstruction, facial discomfort, epistaxis and ocular impairment. Surgical resection represents the gold standard of treatment, allowing for the resolution of clinical manifestations and gross total tumor resection in most cases; the role of adjuvant treatments is unclear. The local recurrence rate after treatment is 26%. Tumor-related mortality is very rare. Background: Biphenotypic sinonasal sarcoma (BSNS) is a low-grade tumor of the sinonasal tract with frequent extension to the orbit and skull base. Due to its rare incidence and recent histopathological and molecular characterization, little data are available in regard to its natural history, treatment and surveillance protocol. Methods: A comprehensive literature review in Embase online electronic databases on BSNS was made. The analyzed factors included the patients' sex and age, presenting symptoms and signs, anatomical origin and pattern of growth of the tumor, immunohistochemical and molecular features, time to treatment, type of treatment, surgical approach, extent of resection, peri- and post-operative complications, adjuvant therapies, clinical outcome, recurrence and overall survival rates. Results: This literature review involved 34 studies for an overall series of 149 cases of BSNS. The female (66.9%) and middle-aged populations (median 54.88 years old) were mainly affected. The most frequent clinical onset was nasal obstruction (81%), followed by facial discomfort (44%), epistaxis (15.5%) and ocular impairment (14.3%). Ethmoid sinus (67.8%) and nasal cavity (45.4%) were the most common anatomical site of tumor origin, while an extension to the orbit and skull base was registered in 28.7% and 24.5% of cases. Surgery was the main treatment, especially in the form of endoscopic endonasal approach (56.9%), and allowed for gross total resection in 79% of cases. The recurrence rate was 26.2%; three cases of tumor-related death were reported. Median follow-up was 4.6 years. Conclusions: Biphenotypic sinonasal sarcoma is a rare and unique tumoral entity in terms of biological and clinical behavior. Based on the current knowledge, surgery plays the leading role in treatment, accounting for gross total tumor resection in most cases, allowing for clinical symptom and sign resolution and presenting a low rate of perioperative complications. The type of approach and the aim of surgery should be assessed case by case according to patient and pathology features and the surgeon's experience, as well as the aim of the treatment. Further studies including large surgical series and with long follow-up are required to define prognostic factors and guidelines of treatment for this peculiar pathological entity.

Background: The role of brain metastases (BM) surgery is of paramount importance for patients' progression-free and overall survival. "En-bloc" and "piecemeal" resection represent the main surgical techniques. Although en-bloc resection remains the best surgical option, it is not widely adopted or feasible as the first choice. We describe our point of view about the en-bloc surgical technique with an illustrative case and discuss its indications with pros and cons through a comprehensive literature review. Materials and methods: A Medline search up to December 2023 in the Embase and PubMed online electronic databases was made and PRISMA statement was followed. An illustrative case of "en-bloc" resection from our surgical series was also added as a technical note. Results: We describe tips and tricks of our surgical technique and added a surgical video from our series. The literature review disclosed 19 studies. Resulting data suggested that "en-bloc" resection, when feasible, provides lesser risk of leptomeningeal dissemination, local recurrence rates, intraoperative bleeding occurrence and perioperative complications; in addition, it preserves the normal anatomy. Conclusions: En-bloc resection is the gold standard technique for surgical treatment of brain metastases especially for patients with superficial lesions that are small in size and far from eloquent areas.

Background: Periodontal disease is an inflammatory, chronic, and multifactorial disease. The objective of this study is to analyze the association between periodontal disease and some disorders such as papillomas (benign lesions), lichen planus (a chronic immune-mediated disorder), leukoplakia (potentially malignant lesions), and oral cancer (malignant lesions). Methods: For this study, 42 patients were recruited whose supragingival and subgingival plaque was qualitatively analyzed using a phase-contrast microscope, which allowed for the detection of compatible bacterial flora (immobile and composed mainly of cocci) indicative of periodontal health and incompatible bacterial flora (mobile and composed mainly of spirochetes) indicative of periodontal pathology. Patients with incompatible bacterial flora were then subjected to a laser-assisted periodontal treatment with irrigation with hydrogen peroxide within the periodontal pockets (a non-surgical laser-assisted periodontal protocol which is referred to as dye-free photodynamic therapy). Results: Based on the 42 patients recruited, there was no association between oral cavity lesions and periodontal pathogenic bacteria. Four of them were found to have incompatible bacterial flora. Indeed, it was found that almost all the patients had been previously instructed in the proper techniques of home oral hygiene, and more than half of them reported that they carried out periodic check-ups by a dental hygienist. Of the four patients with signs and symptoms of periodontitis, two stated a willingness to undergo the non-surgical laser-assisted periodontal protocol and showed improvements in periodontal indices such as CAL, PPD, and BoP. Conclusions: hygienists and dentists are determining factors in the prevention of periodontal disease and for the maintenance of good oral health. [ABSTRACT FROM AUTHOR]

The goals of the current research were to assess the immediate impact of invasive wild boar (Sus scrofa L.) in olive orchards of southern Italy. Over a one-year study, in grubbed and ungrubbed areas, we measured the seasonal changes on the fast soil biological and chemical responses at depths of 0–15 cm and 15–40 cm, and several leaf and fruit characteristics. The impact factor, IFG, was used to quantify the effects of wild boar on individual soil parameters. Grubbing induced an increase in the soil moisture at both depths. Soil pH, organic matter, and C/N ratio were higher in grubbed soils at 0–15 cm and lower at 15–40 cm compared to ungrubbed soils. These trends were reflected in the higher microbial community biomass and the inhibition of fungal fraction in grubbed topsoil, while an opposite tendency at 15–40 cm was found. Microbial biomass had the highest IFG in topsoil (94%) and metabolic quotient (85%) at a 15–40 cm depth. Microbial stress condition and C loss were found in grubbed soil at both depths. Furthermore, these soils were also shown to be of lower quality than ungrubbed soils, especially at 0–15 cm (SQI = 0.40 vs. 0.50, respectively). A stronger negative impact of wild boar grubbing was observed in the Autumn/Winter and for fruit polyphenol content.

Carbapenem antibiotics are the most effective antimicrobials for the treatment of infections caused by the most resistant bacteria. They belong to the category of β-lactams that include the penicillins, cephalosporins, monobactams and carbapenems. This class of antimicrobials has a broader spectrum of activity than most other beta-lactams antibiotics and are the most effective against Gram-positive and Gram-negative bacteria. All β-lactams antibiotics have a similar molecular structure: the carbapenems together with the β-lactams. This combination gives an extraordinary stability to the molecule against the enzymes inactivating the β-lactams. They are safe to use and therefore widespread use in many countries has given rise to carbapenem resistance which is a major global public health problem. The carbapenem resistance in some species is intrinsic and consists of the capacity to resist the action of antibiotics with several mechanisms: for the absence of a specific target, or an intrinsic difference in the composition of cytoplasmatic membrane or the inability to cross the outer membrane. In addition to intrinsic resistance, bacteria can develop resistance to antibiotics with several mechanisms that can be gathered in three main groups. The first group includes antibiotics with poor penetration into the outer membrane of bacterium or antibiotic efflux. The second includes bacteria that modify the target of the antibiotics through genetic mutations or post-translational modification of the target. The third includes bacteria that act with enzyme-catalyzed modification and this is due to the production of beta-lactamases, that are able to inactivate carbapenems and so called carbapenemases. In this review, we focus on the mode of action of carbapenem and the mechanisms of carbapenem resistance.

Abstract The combined used of thrombectomy with direct intravenous thrombolytic infusion provided effective treatment of DVT and uncovered an underlying left common iliac vein stenosis, which was successfully managed by angioplasty and stenting.

Purpose: To evaluate the potential confounding effect of concomitant pneumonia (PNM) on lung ultrasound (LUS) B-lines in acute heart failure (AHF).Methods: We enrolled 86 AHF patients with (31 pts, AHF/PNM) and without (55 pts, AHF) concomitant PNM. LUS B-lines were evaluated using a combined antero-lateral (AL) and posterior (POST) approach at admission (T0), after 24 h from T0 (T1), after 48 h from T0 (T2) and before discharge (T3). B-lines score was calculated at each time point on AL and POST chest, dividing the number of B-lines by the number of explorable scanning sites. The decongestion rate (DR) was calculated as the difference between the absolute B-lines number at discharge and admission, divided by the number of days of hospitalization. Patients were followed-up and hospital readmission for AHF was considered as adverse outcome.Results: At admission, AHF/PNM patients showed no difference in AL B-lines score compared with AHF patients [AHF/PNM: 2.00 (IQR: 1.44–2.94) vs. AHF: 1.65 (IQR: 0.50–2.66), p = 0.072], whereas POST B-lines score was higher [AHF/PNM: 3.76 (IQR: 2.70–4.77) vs. AHF = 2.44 (IQR: 1.20–3.60), p < 0.0001]. At discharge, AL B-lines score [HR: 1.907 (1.097–3.313), p = 0.022] and not POST B-lines score was found to predict adverse events (AHF rehospitalization) after a median follow-up of 96 days (IQR: 30–265) in the overall population.Conclusions: Assessing AL B-lines alone is adequate for diagnosis, pulmonary congestion (PC) monitoring and prognostic stratification in AHF patients, despite concomitant PNM.

In this study, Sea Water Bread (SWB), made with food grade sea water was compared with control bread made with Tap Water (TWB). Sea water’s influence on chemical-nutritional properties of bread was investigated. Contents of salt, macro/micro-elements, basic nutrients, polyphenols, antioxidant activity, olfactory characteristics, and volatile components were analyzed. Chlorides’ analysis showed SWB had a lower salt content than TWB and it was confirmed by ICP-OES investigation. An electronic nose confirmed differences between the groups of aromatic molecules of the bread typologies, as well as the profiles of the volatile molecules by GC-MS.

Abstract Background Palmitoylethanolamide (PEA) belong to endocannabinoid family, a group of fatty acid amides. PEA has been proven to have analgesic and anti-inflammatory activity and has been used in several controlled studies focused on the management of chronic pain among adult patients with different underlying clinical conditions. Methods/design A literature search will be performed using PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL). The population will be patients who have chronic pain, the intervention will be the administration of PEA alone or in combination with other drugs for the pain management; the comparison will be the standard therapy in accordance with the current guidelines for the treatment of pain. The Outcomes will be the reduction of pain not restricted to specific scales laying out the pain outcome data described in the included studies. Discussion This scoping review aims to describe the clinical applications of the PEA in chronic pain management and its outcome.

(1) Background: healthcare-associated infections are one of the most frequent adverse events in healthcare delivery worldwide. Several antibiotic resistance mechanisms have been developed, including those to carbapenemase. Cefiderocol (CFD) is a novel siderophore cephalosporin designed to treat carbapenem-resistant bacteria. (2) Methods: we performed a systematic review of all cases reported in the literature to outline the existing evidence. We evaluated real-world evidence studies of CFD in the treatment of carbapenem-resistant (CR) bacteria. (3) Results: a total of 19 publications treating cases of infection by CR bacteria were included. The three most frequent CR pathogens were Acinetobacter baumannii, Pseudomonas aeruginosa, and Klebsiella pneumoniae. A regimen of 2 g every 8 h was most frequently adopted for CFD with a mean treatment duration of 25.6 days. CFD was generally well tolerated, with fewer side effects. The success rate of CFD therapy was satisfactory and almost 70% of patients showed clinical recovery; of these, nearly half showed negative blood cultures and infection-free status. (4) Conclusions: This review indicates that CFD is active against important GN organisms including Enterobacteriaceae, P. aeruginosa, and A. baumannii. CFD seems to have a safe profile.
