Prognostic Significance of Multifactorial Analysis in Complex Cervical Aero-Digestive Trauma Cases.

Background and Objectives: In the context of complex aerodigestive cervical traumas, the prognosis and outcome heavily depend on risk factors, particularly injuries to the larynx, trachea, major digestive tissues, cervical vertebrae, and vascular structures. With the increasing prevalence of trauma as a public health concern, there is a pressing need for epidemiological research and the implementation of preventative measures. The purpose of this research is to establish the profile of the predictable impact factors that determine the prognosis of patients with complex cervical trauma. Methods and Methods: The study group consisted of 106 patients with complex cervical trauma pathology developed by various mechanisms such as car accidents, home-related accidents, aggression, gunshot wounds, and self-inflicted attempts, resulting in hospitalization in the E.N.T. Clinic at "St. Spiridon" Iași Hospital, from 2012 to 2016; medical records were the source of the collected data. Results: Hemodynamic instability upon admission associated with age, muscle and laryngeal injuries, and anemia were identified as negative prognostic factors. Additionally, the utilization of imaging-based paraclinical investigations for diagnosing traumatic lesions emerged as a positive prognostic factor in managing this pathology. The management of penetrating cervical trauma remains a subject of debate, with some advocating for surgical exploration beyond the platysma layer in all cases, while others argue for a more selective conservative approach due to a high rate of negative explorations. Conclusions: The statistical evaluation of epidemiological, clinical, lesion, paraclinical, and therapeutic parameters is needed to establish predictable risk factors in the prognosis of complex aerodigestive cervical trauma.

Anatomical Variants of Internal Carotid Artery-Results from a Retrospective Study.

Background and Objectives: The internal carotid artery (ICA) is a vascular structure that can be easily injured during sinus endoscopic procedures, and surgeons should be familiar with its anatomic variants. The aim of this study was to describe the anatomical variations in the internal carotid artery in relationship to sphenoidal sinuses, using computed tomography (CT). Materials and Methods: In this retrospective study, we evaluated the variations of the ICA in relationship to sphenoidal sinuses in a cohort of 600 patients who were assessed between January 2020 and December 2022 in 'Saint Spiridon' Emergency Hospital, Iasi, Romania. Descriptive statistics were used to characterize our data. Results: The most prevalent anatomical variant was represented by intrasinusal septa with posterior insertion on the ICA (58.6%), followed by procident ICA (58%) and dehiscent ICA (52%). We could not find any statistical significance regarding demographic characteristics among groups. Conclusions: A thorough CT examination should be performed before functional endoscopic sinus surgery, with the identification of anatomical variants of the ICA, in order to prevent its injury with potentially fatal consequences.

Patterns and Characteristics of Midface Fractures in North-Eastern Romania.

Midface fractures are common injuries that are the result of interpersonal violence, traffic accidents, falls, work-related accidents, sports-related accidents, or animal aggression. In the northeastern part of Romania, these injuries are a significant health concern that, if left untreated, may lead to functional and esthetic sequelae. Background and Objectives: This study aims to update the statistical data available to help promote a different lifestyle, with awareness campaigns to prevent aggression, accidents, and domestic violence. Materials and Methods: This research was conducted over five years and included 651 patients of both sexes, with ages between 3 and 95 years, that addressed our center for midface fracture treatment. Results: The authors of this study found that men are more predisposed to fractures of the middle third of the face, with anterior laterofacial fractures being the most common type of fracture. Interpersonal violence was the most incriminated etiology for all midface fractures. Conclusions: The present study regarding midfacial fractures shows similar results compared to the medical literature. These findings could help promote a different lifestyle, with awareness campaigns to prevent aggression, accidents, and domestic violence.

Multidisciplinary Therapeutic Management in Complex Cervical Trauma.

Background and Objectives: In the current literature, mandatory surgical exploration is a controversial topic, with some advocating for it and others against it, proposing a selective conservative management. This multidisciplinary therapeutic approach is based on clinical examination and serial paraclinical explorations associated with supportive drug treatment. Materials and Methods: The study group consisted of 103 patients with complex cervical trauma pathology produced by various mechanisms such as car or domestic accidents, aggression, ballistic trauma, self-inflicted attempts, hanging or strangulation hospitalized in the Ear, Nose and Throat (E.N.T.) Clinic, at "St. Spiridon" Iași Hospital, between 2012 and 2016. Results: The universal clinical indication for urgent surgical exploration of the patient with complex cervical trauma is the presence of the following symptoms: unstable vital signs, significant pulsatile bleeding, hematoma with a substantial increase in size, shock, airway obstruction, open airway wound, hematemesis, or hemoptysis. In this context, we considered it worthwhile to research the management of complex cervical trauma in a reference university medical center, alongside the analysis of the patient's characteristics under different aspects (demographic, pathological aspects, therapeutic). Conclusions: Complex cervical trauma has a variety of clinical aspects, with a variable evolution, which involves multidisciplinary therapeutic management. The increasing trauma rate is one of the main public health problems, requiring epidemiological studies, and the implementation of control strategies.

The Diagnostic Accuracy of Pure-Tone Audiometry Screening Protocols for Vestibular Schwannoma in Patients with Asymmetrical Hearing Loss-A Systematic Review and Meta-Analysis.

(1) Background: Magnetic resonance imaging (MRI) is the gold standard investigation for all patients who present with asymmetrical hearing loss (AHL) and a high index of suspicion for vestibular schwannoma (VS). However, pure-tone audiometry (PTA) is an investigation that can be used for the screening of these patients in order to reduce the costs. The aim of this systematic review and meta-analysis was to evaluate the diagnostic accuracy of different PTA protocols for VS in patients with ASHL, when compared with MRI; (2) Methods: Medline, Embase, and Cochrane databases were used to find relevant studies. All prospective and retrospective observational studies that evaluated the accuracy of PTA protocols for the screening of VS were assessed, according to the international guidelines; (3) Results: We analyzed seven studies (4369 patients) of poor-to-moderate quality. Their pooled sensitivity was good (0.73-0.93), but their specificity was low (0.31-0.60). All protocols were located in the right lower quadrant on the likelihood scattergram, and the post-test probabilities for positive and negative diagnosis of these protocols were extremely low; (4) Conclusions: PTA protocols cannot be used for a proper screening or diagnosis of vestibular schwannoma despite their good sensibility, and MRI remains the gold standard for this purpose.

Improving the Treatment Outcome of Naso-Orbito-Ethmoido-Maxillary Fractures Using Virtual Three-Dimensional Anthropometric Data.

BACKGROUND: Naso-orbito-ethmoido-maxillary (NOEM) fractures are usually the result of a high or moderate intensity impact to the upper midface. These types of fractures are difficult to treat and are frequently misdiagnosed. Craniometric analysis can be of real aid in the treatment of NOEM complex fractures by establishing midfacial proportions. AIM: This study aims to establish the distances between selected anthropometric points and midfacial proportions found in the adult Caucasian population and to determine if any differences exist between genders. METHODOLOGY: Measurements between anthropometric points, nasion (N), dacryon (D), infraorbital foramen (IOF), frontomalare orbitale (FMO), rhinion (Rhi) and porion (Po), were made on 3D models obtained using patients' CT exams. RESULTS: Significant differences were found between genders for the orbital dimensions represented by N-FMO (p = 0.000), N-IOF (p = 0.000), Rhi-FMO (p = 0.000), Rhi-IOF (p = 0.000), nose bridge width N-D (p = 0.001), Rhi-D (p = 0.016), D-D (p = 0.038) and the projection of the nose evaluated by Rhi-Po (p = 0.000), N-Po (p = 0.000), while a t-test showed that there are no significant differences between males and females for the N-Rhi (p = 0.254). CONCLUSIONS: The values of these measurements can be utilized during skeletal reconstruction after NOEM fractures, especially for bilateral comminuted fractures where no points of comparison are available.

The Impact of Chronic Suppurative Otitis Media with and without Cholesteatoma in Patients from Northeastern Romania.

Quality of life is a widely used concept that tends to become an important part of clinical management. The present study performs an analysis of the impact of suppurative chronic otitis media with and without cholesteatoma on quality of life, using the COMQ-12 questionnaire. It was applied to a group of 40 healthy people and to 40 patients before surgery, and the answers to the questions were analyzed and correlated with socioeconomic factors. After the confirmation of the diagnosis based on clinical and imaging information, the patients completed the COMQ-12 questionnaire. It was observed that the chronic ear problems had negative impacts of varying degrees on daily and long-term activities. The evaluation and analysis of information can be used in setting therapeutic targets.

IL-1α, IL-6 and IL-8 serum values in patients with chronic suppurative otitis media.

Inflammatory mediators play an important role in the pathogenesis of otitis media by initiating and maintaining an inflammatory response to infection. The presence of inflammatory mediators may be one of the reasons, in some patients, for acute otitis media transforming into chronic otitis media. The present study included 60 patients admitted to the Clinical Rehabilitation Hospital, Iasi, Romania, for surgery. The control group comprised 30 healthy individuals. Serum levels of interleukin 1α (IL-1α), interleukin 6 (IL-6) and interleukin 8 (IL-8) were measured prior to surgery and were compared among patients with chronic suppurative otitis media (CSOM), cholesteatoma and cholesteatoma recidivism and the control group. High serum levels of interleukins were recorded in all the groups compared to the healthy control group. IL-6 and IL-8 had the highest value in patients with CSOM and IL-1α had the highest value in patients with cholesteatoma recidivism. Thus, we can consider that inflammatory mediators play a central role in the pathogenesis of CSOM and cholesteatoma by maintaining a systemic and local inflammatory response.

Nanomedicine to modulate immunotherapy in cutaneous melanoma (Review).

Cancer immunotherapy has shifted the paradigm in cancer treatment in recent years. Immune checkpoint blockage (ICB), the active cancer vaccination and chimeric antigen receptor (CAR) for T-cell-based adoptive cell transfer represent the main developments, achieving a surprising increased survival in patients included in clinical trials. In spite of these results, the current state-of-the-art immunotherapy has its limitations in efficacy. The existence of an interdisciplinary interface involving current knowledge in biology, immunology, bioengineering and materials science represents important progress in increasing the effectiveness of immunotherapy in cancer. Cutaneous melanoma remains a difficult cancer to treat, in which immunotherapy is a major therapeutic option. In fact, enhancing immunotherapy is possible using sophisticated biomedical nanotechnology platforms of organic or inorganic materials or engineering various immune cells to enhance the immune system. In addition, biological devices have developed, changing the approach to and treatment results in melanoma. In this review, we present different modalities to modulate the immune system, as well as opportunities and challenges in melanoma treatment.

Predictive Value of HPV, p53, and p16 in the Post-Treatment Evolution of Malignant Tumors of the Oropharynx and Retromolar Trigone-Oropharynx Junction.

Background and objectives: Knowledge of the interactions and influences of infectious, genetic, and environmental factors on the evolution and treatment response of malignant tumors is essential for improving the management of the disease and increasing patient survival. The objective of this study was to establish the contribution of human papillomavirus (HPV), as well as p53 and p16 tumor markers, alongside associated factors (smoking and alcohol consumption), in the progression of malignancies located in the oropharynx and at the retromolar trigone-oropharyngeal junction. Materials and Methods: We performed a prospective study including 50 patients with malignant tumors of the oropharynx and retromolar trigone-oropharyngeal junction. In all patients, the presence and type of HPV were determined, as well as the status of the tumor markers p53 and p16. The associated risk factors, biopsy results, treatment method, and post-treatment evolution were all documented. Statistical analyses were performed to evaluate the correlations between the determining factors and their influence on the post-treatment evolution. An overall increased survival rate was found in HPV(+) patients. Results: Our study outlined the prevalence of different high-risk subtypes of HPV from the ones presented by other studies, suggesting a possible geographic variation. Correlations between the p53 and p16 statuses and patient survival could be established. The association of smoking and alcohol consumption strongly correlated with an unfavorable evolution. Conclusions: Awareness of the differences in the post-treatment evolution of the patients in relation to the presence of the factors determined in our study could change the future management of such cases for ensuring improved treatment outcomes.

Correlations between HPV, p53 and p16 in malignancies involving the retromolar trigone-oropharynx junction.

The aim of this study is to enhance knowledge regarding the behavior of human papilloma virus (HPV)-associated malignancies between two territories - maxillofacial and otorhinolaryngology. The HPV status and genotype, p16 and p53 expression were performed in 50 patients with malignancies located at the junction between the oropharynx and retromolar trigone alone or oropharynx spread to the junction. These were correlated with the treatment response, prognosis and survival of this kind of tumor located in oral posterior region, marking the transition between two territories (maxillofacial and otorhinolaryngology) of the selected cases. Results showed better treatment outcome and improved prognosis in HPV-positive compared to HPV-negative patients, and a strong link between HPV presence and p16 expression. Multimodal treatment including surgery, radiotherapy and chemotherapy provided the best results, although surgery was only an option in a limited number of cases, due to the advanced stage at presentation and extension in the surrounding tissues, considering the complex anatomy of the area. In the context of the increasing incidence of HPV-positive head and neck cancer, HPV testing together with molecular profiling for p16 and p53 tumor markers could help diagnose malignancies in the initial stages, and also provide important clues towards a targeted, more efficient treatment.

Vestibular sensory functional status of cochlear implanted ears versus non-implanted ears in bilateral profound deaf adults.

Patients with hearing loss who underwent cochlear implantation can present symptomatic or asymptomatic vestibular damages earlier or later after the surgery. The vestibular permanent lesions could be acute, produced by surgical trauma or could be progressive due to local morphological changes made by the presence of the portelectrode in the inner ear (fibrosis related, ossification, basilar membrane distortion, endolymphatic hydrops). Besides histopathological findings in inner ear of cochlear implanted patients, the vestibular permanent damages could be found by assessment of clinical vestibular status. This study reports the sensorial vestibular functional findings for adults in cochlear implanted ears related to the electrode insertion type (cochleostomy or round window approach) and comparing to non-implanted deaf ears. A total of 20 adult patients with 32 cochlear implanted ears (12 patients with binaural cochlear implant and eight with monoaural) were selected for postoperatory vestibular examination by cervical and ocular vestibular myogenic potentials and vestibular caloric tests. The same tests were made for a control group of 22 non-implanted deaf ears. Functional testing results were reported related to the electrode insertion approach. For the cochleostomy group, we found different deficits: in 40% for saccular function, 44% for utricular function, and 12% horizontal canal dysfunction. In round window group, the deficit was present in 14.29% for saccular function, 28.57% for utricular function, and 28.58% for horizontal canal. In 46.88% of implanted ears, the vestibular function was completely preserved on all tested sensors. In conclusion, the vestibular functional status after inner ear surgery presents sensorial damages in 53.12% ears compare with the vestibular dysfunction existing in 50% of deaf non-operated ears. Round window insertion allows for better conservation of the vestibular function.

The anatomo-radiological study of unusual extrasinusal pneumatizations: superior and supreme turbinate, crista galli process, uncinate process.

INTRODUCTION: One of the aspects that have an influence on rhinosinusal endoscopic surgery is extrasinusal pneumatization, which can also affect less common structures at this level. The pneumatization of the superior and supreme turbinates, uncinate process and crista galli are perfect examples of this situation. The diagnosis is made only through imaging methods. MATERIALS AND METHODS: This is a retrospective anatomo-radiological study analyzing 205 CT scans of the facial sinuses performed over a three years period. All patients were symptomatic and the CT scans were performed to assess the cases prior to surgery. Ninety-seven patients were females and 108 males, aged between 18 and 91 years. RESULTS: The prevalence of pneumatization and the prevalence of the different pneumatization types (superior and supreme turbinate, uncinate process and crista galli) were determined. CONCLUSIONS: The pneumatization of the supreme turbinate (10.24%) was less common than that of the superior turbinate (29.76%) and affected all its anatomical variations (A, B, C). Pneumatization of the crista galli process was recorded in 22.92% of the cases, especially in association with type 2, while the prevalence of pneumatized uncinate process was of only 3.41% (uni- or bilateral).
