Trattamento dell’adenoma pleomorfo delle ghiandole salivari: nostra esperienza

Premessa. L’adenoma pleomorfo è un tumore epiteliale benigno delle strutture ghiandolari che si localizza prevalentemente nella ghiandola parotide. Scopo. Analizzare i dati dei pazienti trattati per adenoma pleomorfo delle ghiandole salivari presso la nostra struttura al fine di valutare la strategia chirurgica. Pazienti e metodi. Studio retrospettivo di un periodo di 15 anni durante il quale sono stati trattati 347 pazienti affetti da adenoma pleomorfo delle ghiandole salivari. Di tutti i pazienti sono stati presi in considerazione: sesso, età, sede del tumore, procedura chirurgica, complicanze postoperatorie, recidive. Risultati. L’adenoma pleomorfo originava prevalentemente nella parotide (89,1%), raramente nelle altre ghiandole salivari. Il tumore era più frequente nelle donne che negli uomini (F:M = 1,5). L’età media era 43,43 anni. L’enucleazione pericapsulare dei tumori parotidei è risultata essere la procedura chirurgica più utilizzata. Le altre procedure utilizzate sono state: parotidectomia superficiale, parotidectomia totale conservativa, esceresi completa della ghiandola sottomandibolare e asportazione radicale dei tumori del palato. Le complicanze postoperatorie sono state: paralisi facciale transitoria in 18 pazienti e sindrome di Frey in 2 pazienti. In nessun paziente sono state riscontrate recidive nel periodo di follow-up (25-177 mesi). Conclusioni. Gli aspetti epidemiologici dell’adenoma pleomorfo delle ghiandole salivari osservati nel nostro studio sono sovrapponibili a quelli riportati in letteratura; lo studio dimostra inoltre che l’enucleazione pericapsulare è una valida alternativa alla parotidectomia superficiale per la maggior parte delle localizzazioni parotidee, essendo associata ad una minore morbilità senza che sia compromessa la radicalità oncologica

Linfoma malt primario de la lengua

Los linfomas derivados de los tejidos linfoides asociados a las mucosas (MALT) primarios de la lengua son infrecuentes. Se documenta el caso de una paciente de 80 años de edad, con un tumor en el dorso de la lengua filiado histológicamente como linfoma extranodal de células B. Se sugiere como posible origen del linfoma un proceso reactivo de origen desconocido, al presentar las glándulas salivales menores adyacentes al tumor un cuadro compatible con una sialadenitis mioepitelial.Primitive malignant lymphoma mucosa associated lymphoid tissue (MALT) on the tongue are rare entities. We report here a case of an old woman (80 years old) with a tumor in the dorsum of the tongue, which was histologically diagnosed as an extra-nodal marginal B cell lymphoma. An inflammatory reaction resembling myoepithelial sialoadenitis was observed in the minor salivary glands adjacent at the tumour, suggesting a possible derivation of the lymphoma from a previous reactive process of unknown origin

A case of emergency reconstructive surgery following facial destructive gunshot wounds: clinical and medico‐legal assessments.

Background. Facial gunshot wounds present a complex challenge to both medical professionals and victims with significant physical, psychological, and economic implications for those who suffer these types of injuries. Reconstructive surgery offers satisfactory aesthetic and functional outcomes, improving a patient’s quality of life. In these cases, the surgical procedure may encompass additional phases beyond those initially identified based on the type of wound and the extent of tissue destruction. As a result, each case necessitates thorough evaluation to determine an appropriate strategy. Nonetheless, it is worth noting that the outcomes achieved in terms of both aesthetics and functionality in this domain have the potential to be excellent. Case presentation. A 66-year-old man attempted suicide with a shotgun, causing severe facial injuries and fractures. He had a history of depression and was taken to the emergency department promptly. CT scans revealed brain and facial bone injuries, and he underwent surgery to control bleeding and tracheostomy. Postoperative recovery was successful. The patient’s condition stabilized, and he was discharged after 10 days. Follow-up visits showed gradual healing. Despite an offer for further facial reconstruction, he declined, satisfied with the achieved results. Conclusions. The present case report is intended to support the argument that effective facial reconstruction should be considered in the medico-legal assessment. It could be beneficial to introduce a new classification system and personalized evaluation methods with careful consideration given to treatment costs (which can be very high) and expected results. Since reconstructive surgery modifies damage and impacts the long-term costs of permanent impairments, its inclusion in the decision-making process would promote improved personalized care

Influence of the teaching program on the learning in knowledge and practice of osteonecrosis of the jaws produced by antireasorptives in dental students of the Principality of Asturias (Spain)

This study aims to evaluate the influence of changes in the teaching contents on medication-related osteonecrosis of the jaw may have on the knowledge and the capacity for practical case resolution about this pathology. A cross-sectional descriptive study was conducted through a survey divided into four sections: degree of means of knowledge acquisition, habitual practice and ability to solve clinical cases. The total number of respondents (n = 225) was divided into two groups: Group A (Year 2015-2016) and Group B (Year 2016-2017). The students in Group B received more teaching content on the subject than group A. A total of 175 survey responses were collected. The internet was the preferred tool for continuing education in both groups. The best known bisphosphonates (BPs) were Alendronate (Fosamax®: 56.9% Group A, 67.5% Group B) and Zoledronic Acid (Zometa®: 56.9% Group A, 51.8% Group B). A low percentage of students (37.9% Group A, 43.4% Group B) acknowledged the existence of other drugs that could also cause osteonecrosis of the jaws. Regarding the correct resolution of practical cases, the respondents of Group B reached a significantly higher score (5.67) than the score observed in Group A (4.04). Training on medication-related osteonecrosis among dental students is susceptible to improvement. Introducing minor changes in the teachings allows this goal to be successfully achieved

Discordant identification of pediatric severe sepsis by research and clinical definitions in the SPROUT international point prevalence study

Introduction: Consensus criteria for pediatric severe sepsis have standardized enrollment for research studies. However, the extent to which critically ill children identified by consensus criteria reflect physician diagnosis of severe sepsis, which underlies external validity for pediatric sepsis research, is not known. We sought to determine the agreement between physician diagnosis and consensus criteria to identify pediatric patients with severe sepsis across a network of international pediatric intensive care units (PICUs). Methods: We conducted a point prevalence study involving 128 PICUs in 26 countries across 6 continents. Over the course of 5 study days, 6925 PICU patients <18 years of age were screened, and 706 with severe sepsis defined either by physician diagnosis or on the basis of 2005 International Pediatric Sepsis Consensus Conference consensus criteria were enrolled. The primary endpoint was agreement of pediatric severe sepsis between physician diagnosis and consensus criteria as measured using Cohen's ?. Secondary endpoints included characteristics and clinical outcomes for patients identified using physician diagnosis versus consensus criteria. Results: Of the 706 patients, 301 (42.6 %) met both definitions. The inter-rater agreement (? ± SE) between physician diagnosis and consensus criteria was 0.57 ± 0.02. Of the 438 patients with a physician's diagnosis of severe sepsis, only 69 % (301 of 438) would have been eligible to participate in a clinical trial of pediatric severe sepsis that enrolled patients based on consensus criteria. Patients with physician-diagnosed severe sepsis who did not meet consensus criteria were younger and had lower severity of illness and lower PICU mortality than those meeting consensus criteria or both definitions. After controlling for age, severity of illness, number of comorbid conditions, and treatment in developed versus resource-limited regions, patients identified with severe sepsis by physician diagnosis alone or by consensus criteria alone did not have PICU mortality significantly different from that of patients identified by both physician diagnosis and consensus criteria. Conclusions: Physician diagnosis of pediatric severe sepsis achieved only moderate agreement with consensus criteria, with physicians diagnosing severe sepsis more broadly. Consequently, the results of a research study based on consensus criteria may have limited generalizability to nearly one-third of PICU patients diagnosed with severe sepsis

Changes in hospital admissions for facial fractures during and after COVID 19 pandemic: national multicentric epidemiological analysis on 2938 patients

PurposeThe objective of this multicenter study was to examine the differences in maxillo-facial fractures epidemiology across the various phases of the SARS-CoV-2 pandemic.MethodsThis is a retrospective study on patients who underwent surgery for facial bone fractures in 18 maxillo-facial surgery departments in Italy, spanning from June 23, 2019, to February 23, 2022. Based on the admission date, the data were classified into four chronological periods reflecting distinct periods of restrictions in Italy: pre-pandemic, first wave, partial restrictions, and post-pandemic. Epidemiological differences across the groups were analysed.ResultsThe study included 2938 patients. A statistically significant difference in hospitalization causes was detected between the pre-pandemic and first wave groups (p = 0.005) and between the pre-pandemic and partial restriction groups (p = 0.002). The differences between the pre- and post-pandemic groups were instead not significant (p = 0.106). Compared to the pre-pandemic period, the number of patients of African origin was significantly higher during the first wave and the post-pandemic period. No statistically significant differences were found across the periods concerning gender, age, fracture type, treatment approach, and hospital stay durationConclusionsThe COVID-19 pandemic brought about significant changes in fracture epidemiology, influenced by the restrictive measures enforced by the government in Italy. Upon the pandemic's conclusion, the fracture epidemiology returned to the patterns observed in the pre-pandemic period

Comparison of Pediatric Severe Sepsis Managed in U.S. and European ICUs

Copyright © 2016 by the Society of Critical Care Medicine and the World Federation of Pediatric Intensive and Critical Care Societies.Objectives: Pediatric severe sepsis remains a significant global health problem without new therapies despite many multicenter clinical trials. We compared children managed with severe sepsis in European and U.S. PICUs to identify geographic variation, which may improve the design of future international studies. Design: We conducted a secondary analysis of the Sepsis PRevalence, OUtcomes, and Therapies study. Data about PICU characteristics, patient demographics, therapies, and outcomes were compared. Multivariable regression models were used to determine adjusted differences in morbidity and mortality. Setting: European and U.S. PICUs. Patients: Children with severe sepsis managed in European and U.S. PICUs enrolled in the Sepsis PRevalence, OUtcomes, and Therapies study. Interventions: None. Measurements and Main Results: European PICUs had fewer beds (median, 11 vs 24; p < 0.001). European patients were younger (median, 1 vs 6 yr; p < 0.001), had higher severity of illness (median Pediatric Index of Mortality-3, 5.0 vs 3.8; p = 0.02), and were more often admitted from the ward (37% vs 24%). Invasive mechanical ventilation, central venous access, and vasoactive infusions were used more frequently in European patients (85% vs 68%, p = 0.002; 91% vs 82%, p = 0.05; and 71% vs 50%; p < 0.001, respectively). Raw morbidity and mortality outcomes were worse for European compared with U.S. patients, but after adjusting for patient characteristics, there were no significant differences in mortality, multiple organ dysfunction, disability at discharge, length of stay, or ventilator/vasoactive-free days. Conclusions: Children with severe sepsis admitted to European PICUs have higher severity of illness, are more likely to be admitted from hospital wards, and receive more intensive care therapies than in the United States. The lack of significant differences in morbidity and mortality after adjusting for patient characteristics suggests that the approach to care between regions, perhaps related to PICU bed availability, needs to be considered in the design of future international clinical trials in pediatric severe sepsis

Acute kidney injury in pediatric severe sepsis : An independent risk factor for death and new disability

Objectives: The prevalence of septic acute kidney injury and impact on functional status of PICU survivors are unknown. We used data from an international prospective severe sepsis study to elucidate functional outcomes of children suffering septic acute kidney injury. Design: Secondary analysis of patients in the Sepsis PRevalence, OUtcomes, and Therapies point prevalence study: acute kidney injury was defined on the study day using Kidney Disease Improving Global Outcomes definitions. Patients with no acute kidney injury or stage 1 acute kidney injury ("no/mild acute kidney injury") were compared with those with stage 2 or 3 acute kidney injury ("severe acute kidney injury"). The primary outcome was a composite of death or new moderate disability at discharge defined as a Pediatric Overall Performance Category score of 3 or higher and increased by 1 from baseline. Setting: One hundred twenty-eight PICUs in 26 countries. Patients: Children with severe sepsis in the Sepsis PRevalence, OUtcomes, and Therapies study. Interventions: None. Measurements and Main Results: One hundred two (21%) of 493 patients had severe acute kidney injury. More than twice as many patients with severe acute kidney injury died or developed new moderate disability compared with those with no/mild acute kidney injury (64% vs 30%; p Conclusions: In a multinational cohort of critically ill children with severe sepsis and high mortality rates, septic acute kidney injury is independently associated with further increased death or new disability.</p
