Purpose: This study aimed to evaluate the outcomes of Pelnac assisted by vacuum sealing drainage in managing severe avulsion injuries of the fingers. Methods: This prospective study was conducted from May 2017 to September 2023, involving 12 consecutive patients with severe avulsion injuries of the fingers. Patients underwent single-stage or two-stage procedures employing Pelnac assisted by vacuum sealing drainage (VSD) for the management of severe avulsion injuries of the fingers. Post-operative follow-up was routinely scheduled, and aesthetic and functional outcomes, sensory recovery, complications were recorded. Results: Twelve patients were included in the analysis, consisting of 9 males and 3 females, with a mean age of 30.6 ± 11.0 years. All patients presented with severe damage to tendons and deep tissues, as well as varying degrees of bone exposure and injury, with average defect area of 36.9 cm² (range, 11 to 180 cm²). At the final follow-up (mean, 14 months; range, 12 to 29 months), the average score on the Fingertip Injuries Outcome Score (FIOS) was 14.3 (SD 3.9, range 10 to 22), with 6 patients achieving excellent result, 4 classified as good and 2 as fair. Patients reported an average satisfaction score of 74.0 (SD 11.6; range 51 to 94) regarding the aesthetic appearance. The average score on the Vancouver Scar Scale score was 2.3 (SD 2.1, range 1.0 to 7.4). Ten patients reported normal or near-normal sensation, while 2 patients experienced slight sensory loss. The average score on the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire was 13.2 (SD 8.5, range 0 to 47). No infections or hematomas were reported during hospitalization or after discharge. Conclusion: Pelnac, assisted by VSD, proved to be an effective approach for managing severe avulsion injuries of the fingers. This approach can be considered as a viable alternative for addressing severe injuries or complex wound conditions. [ABSTRACT FROM AUTHOR]

Background: Osteomyelitis secondary to mandibular fracture surgery is rare and complete surgical debridement of necrotic infected tissues is an optimal treatment for it. Subsequent reconstruction is required for bone defect caused by operation. Autogenous, allograft and synthetic bone graft substitutes have become widespread in bone defect treatment. Distraction osteogenesis (DO) was also applied in bone defect reconstruction, even it wasn't conventional therapy in jaw. Case presentation: Here we report a case of a 40-year-old aged man who presented with chronic swelling and pain on the right mandibular masseteric region after mandibular angle and Le Fort II fracture surgery. In six weeks after surgery, CBCT images showed that the fracture ends hadn't heal and the fracture gap had widened significantly. The clinical diagnosis of the patient was right mandibular angle osteomyelitis. After controlling the symptoms of pain and infection with local rinses and systemic antibiotic therapy, the patient underwent segmental resection of the infected bone and DO reconstruction for bone defect simultaneously. Encouragingly, well bone healing and normal occlusion restoration was observed finally. Conclusions: DO could be a valuable alternative therapy to bone grafts for bone defect, even in the case of infection. [ABSTRACT FROM AUTHOR]

Background: Microvascular free tissue transfer is a popular option for reconstruction of the head and neck defects following tumor ablation. Many factors are involved in the achievement of a satisfactory outcome, namely, adequate selection of the donor flap and recipient vessels, proficient anastomosis technique and postoperative care including flap monitoring. Preferential use of end-to-side anastomosis to the internal jugular vein in head and neck reconstruction offers various advantages and has consistently yielded outstanding results. Purpose: Presented is a series of 200 consecutive cases at one institution over 1 year. Method: In our institution, the internal jugular vein (IJV) has had the first priority in the selection of a recipient vein in free-flap head and neck reconstruction. An end-to-side anastomosis with the internal jugular vein has several advantages. Results: We have devised a simple technique of marking the point of anastomosis with a needle prick at two points taking the diameter of pedicle vein to aid in identification of point of anastomosis. Conclusion: This method is very reliable to ascertain the suitable lie of the pedicle vein. The diameter of the lumen for anastomosis is maintained. We had a success rate of 100% with all the cases we applied this technique on. [ABSTRACT FROM AUTHOR]

Aim: To evaluate the surgical and postoperative management strategies that contribute to minimizing the need for prophylactic tracheostomy for airway management in advanced oral cancer surgery. Methods: A retrospective review of the patients who underwent surgery for advanced oral cancer, in our institution from February 2015 to January 2024. Results: In the present review, 66 patients (males, n = 54; females, n = 12; mean age 50.3 years) who were operated for advanced oral cancer (T3, T4 oral squamous cell carcinoma and osteosarcoma of the mandible requiring mandibular resection) in our institution were included. 60 patients (90.9%) had reconstruction after segmental resection of the mandible without the need for prophylactic tracheostomy. Out of these, eighteen patients (27.27%) required segmental resection of the mandible crossing midline. Six patients (9.1%) underwent prophylactic tracheostomy, of which two patients had unilateral tumor and four patients had tumor crossing midline. Comparison of hospital stays between patients who underwent prophylactic tracheostomy and those who did not yielded mean durations of 13.3 days and 7.6 days, respectively. Conclusion: Except a subset of patients with old age, obesity, bulky neck, and those with respiratory compromise, following the present guidelines, prophylactic tracheostomy can be avoided in patients undergoing surgery for advanced oral cancer.

Objective: We conducted a systematic review and meta-analysis to compare venous couplers and hand-sewn techniques for venous anastomosis in head and neck reconstruction., Data Sources: PubMed/MEDLINE and Scopus, databases were searched for relevant publications. Additionally, a manual search was performed in Google Scholar and through reference lists., Review Methods: Retrospective and prospective cohort studies were included. Odds ratios (ORs) and mean differences (MD) were calculated with their 95% confidence intervals (CIs) for each study comparing the 2 groups (coupler vs hand). The inverse variance method was used to combine the effect sizes from the individual studies., Results: A total of 14,053 patients undergoing 14,270 head and neck free flap reconstructions were included from 52 studies. A total of 6080 flaps were performed using a coupling device for the venous anastomoses, while 8190 flaps were performed with the hand-sewn technique. No significant difference was found for the venous thrombosis rate (OR: 1.06, 95% CI: 0.65-1.72), and reoperation rate (OR: 0.93, 95% CI: 0.51-1.70), but a significantly lower failure rate was measured for the coupler group (OR = 0.34, 95% CI: 0.20-0.58). A nonsignificant lower operative time was found for venous anastomoses (MD: -20.5, 95% CI: -51.7 to 10.7) and total surgery (MD: -23.7, 95% CI: -344.3 to 296.8) for the coupler group., Conclusion: Despite the slight advantages observed with venous couplers, the overall outcomes of both techniques are excellent, and the choice of anastomotic technique should be guided by surgeon preference., (© 2025 American Academy of Otolaryngology–Head and Neck Surgery Foundation.)

The human microbiome has garnered tremendous interest in the field of oncology, and microbiota studies in head and neck oncology has also flourished. Given the increasing incidence and mortality of HNSCC, as well as the suboptimal outcomes of available treatments, there is an urgent need for innovative approaches involving the microbiome. This review evaluates the intricate relationship between the microbiome and HNSCC, highlighting the potential of the microbiome as a marker for cancer detection, its role in malignancy, and its impact on the efficacy of conventional treatments like chemotherapy and radiotherapy. The review also explores the effects of treatment modalities on the microbiome and discusses the potential of microbiome alterations to predict and influence treatment toxicities such as mucositis and xerostomia. Further research is warranted to characterize the microbiome-HNSCC association, which holds promise for advancing early diagnosis, enhancing prognostic accuracy, and personalizing treatment strategies to improve patient outcomes. The exploration of the microbiome in clinical trials indicates a burgeoning subject of microbiome-focused therapies, heralding a new frontier in most cancer care., Competing Interests: Declarations.

Objective: Assess the impact of tracheostomy on postoperative morbidity and mortality and examine factors that predicted tracheostomy in head and neck flap patients., Study Design: Retrospective cohort January 2017 to December 2021., Setting: Single tertiary center., Methods: Adult patients undergoing head and neck flap reconstruction were included, excluding cutaneous reconstruction, laryngectomy, or with tracheostomy present at surgery. Patients were routinely extubated immediately following surgery. Univariate and multivariable analyses examined associations between tracheostomy and postoperative outcomes and identified predictors of tracheostomy., Results: We included 193 patients, 69 (35.8%) with tracheostomy and 124 (64.2%) without. Tracheostomy avoidance was associated with no difference in 30-day mortality (P = .531) and with decreased likelihood of 30-day complications (0.019), unplanned return to the operating room (0.021), and discharge to a facility (<0.001) and with 2.2 decrease in length of stay on multivariable analysis (confidence interval [CI]: 0.62-3.82, P = .007). Four patients (2.1%) required reactive tracheostomy with no resulting mortalities. Significant associations with tracheostomy on multivariable analysis included bilateral neck dissections (odds ratio [OR]: 3.13, CI 1.12-9.06, P = .030), number of resected mandibular subsites (OR: 2.65, CI: 1.50-5.67, P = .0023), specimen volume (OR: 1.87, CI: 1.29-2.71, P = .001), body mass index < 20 (OR: 3.80, CI: 1.24-11.64, P = .019), mandibulectomy (OR: 0.04, CI: 0.01-0.22, P < .001), forearm flap (OR: 0.15, CI: 0.05-0.41, P < .001), oral cavity site (OR: 0.21, CI: 0.06-0.73, P = .014), and age > 70 (OR: 0.33, CI: 0.14-0.81, P = .016)., Conclusion: Tracheostomy avoidance is safe in properly selected patients undergoing head and neck flap reconstruction. Multiple factors predicted tracheostomy, which may guide patient selection at other centers., (© 2024 American Academy of Otolaryngology–Head and Neck Surgery Foundation.)

Angiolipoma is a benign mesenchymal tumor and its occurrence in head and neck region is very rare. Only 2 cases of Laryngeal angiolipomas have been reported in the medical literature. We present one such rare case in a 32-year-old male who presented with complaints of change in voice and foreign body sensation in the throat since past 9 months along with features suggestive of obstructive sleep apnoea and dysphagia. Contrast enhanced CT scan of the neck showed a cystic lesion arising from right ventricle extending superiorly till the vallecula, partially obstructing the airway. Suspecting a supraglottic cyst, trans-oral microlaryngoscopic KTP-532 laser assisted excision was planned, intraoperatively a solid tumor was encountered. We discuss herein the clinical presentation and management of this rare neoplasm with review of literature. [ABSTRACT FROM AUTHOR]

Background: The mortality of oral squamous cell cancer (OSCC) in Serbia increased in the last decade. Recent studies on the Serbian population focused mainly on the epidemiological aspect of OSCC. This study aimed to investigate the demographic and imaging features of OSCC in the Serbian population at the time of diagnosis. Methods: We retrospectively analyzed computed tomography (CT) images of 276 patients with OSCC diagnosed between 2017 and 2022. Age, gender, tumor site, tumor volume (CT-TV, in cm3), depth of invasion (CT-DOI, in mm), and bone invasion (CT-BI, in %) were evaluated. TNM status and tumor stage were also analyzed. All parameters were analyzed with appropriate statistical tests. Results: The mean age was 62.32 ± 11.39 and 63.25 ± 11.71 for males and females, respectively. Male to female ratio was 1.63:1. The tongue (36.2%), mouth floor (21.0%), and alveolar ridge (19.9%) were the most frequent sites of OSCC. There was a significant gender-related difference in OSCC distribution between oral cavity subsites (Z=-4.225; p < 0.001). Mean values of CT-TV in males (13.8 ± 21.5) and females (5.4 ± 6.8) were significantly different (t = 4.620; p < 0.001). CT-DOI also differed significantly (t = 4.621; p < 0.001) between males (14.4 ± 7.4) and females (10.7 ± 4.4). CT-BI was detected in 30.1%, the most common in the alveolar ridge OSCC. T2 tumor status (31.4%) and stage IVA (28.3%) were the most dominant at the time of diagnosis. Metastatic lymph nodes were detected in 41.1%. Conclusion: Our findings revealed significant gender-related differences in OSCC imaging features. The predominance of moderate and advanced tumor stages indicates a long time interval to the OSCC diagnosis. [ABSTRACT FROM AUTHOR]

The assessment of lymph node dimensions is a commonly used criterion in analyzing lymphatic involvement related to inflammatory or neoplastic diseases. However, it is important to understand that the interpretation of lymph nodes goes beyond simply considering their size. A pathologic lymph node can present with enlarged dimensions, a heterogeneous appearance, increased cortex thickness, irregular contours, or a lobulated shape. In this context, it is essential to consider not only the dimensions but also the morphology, attenuation, and enhancement of lymph nodes on imaging exams. This article aims to demonstrate how characteristics of lymph nodes, beyond their size, can provide crucial insights that assist in diagnostic reasoning, focusing on computed tomography. By emphasizing different enhancement patterns, attenuation, and the potential contents related to these patterns, the study seeks to show how these features can indicate possible differential diagnoses and guide more accurate clinical assessments., (© 2024.

Background: The reported risk of malignancies (ROM) remains controversial for fine needle aspiration (FNA) of thyroid nodules in the African American (AA) population. Herein, the ROM along with frequency was assessed for each of the Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) diagnostic categories., Materials and Methods: The electronic pathology archive of a large academic hospital was retrospectively searched for cytopathology reports of thyroid nodules in AA patients (2010-2019) and Non-African American (NAA) control cases. The patients' demographic, thyroid nodule characteristics, FNA results using TBSRTC and surgical diagnoses were recorded, whenever available., Results: Three hundred ninety-one cases were identified, 317 females (81.1%) and 74 males (18.9%) with median age 50.0 (SD = 14.4). The mean size of the nodules was 2.1 cm (SD = 1.4). The Bethesda categories were: 5.4% (I), 35.0% (II), 35.3% (III), 7.7% (IV), 3.3% (V) and 13.3% (VI). The overall ROM of thyroid nodules was 43.8% (89/203) on surgical follow-up (203/391). The ROM in each Bethesda categories were: 33.3% (I), 11.6% (II), 35.2% (III), 15.8% (IV), 83.3% (V) and 100% (VI) on surgical follow-up. The frequency of thyroid nodules was higher in AA females; however, the ROM was higher in AA males (48.3%) compared with AA females (41.2%)., Conclusion: The ROM in Categories I, II and III was higher than those reported in the TBSRTC while being similar in Categories IV, V and VI. The overall risk of thyroid malignancy in our AA patient population was higher than those in the literature. The overall ROM of thyroid nodules in AA males was higher than of AA females., (© 2024 John Wiley & Sons Ltd.)

Background: The aim of this study was to investigate whether using an innervated vascularized iliac bone flap could effectively prevent bone resorption and maintain sensory function in the lower lip., Methods: In the innervated group, the deep circumflex iliac artery and recipient vessels were anastomosed, with simultaneous microanastomosis of ilioinguinal nerve, mental nerve, and inferior alveolar nerve. Conversely, the control group underwent solely vascular anastomosis. Computed tomography was used to assess bone quality. Sensory recovery of the lower lip was recorded using 2-point discrimination and current perception threshold testing., Results: The study comprised a total of 40 subjects, with each group accounting for 20 participants, equally distributed in terms of gender. Hounsfield unit loss was significantly lower in the innervated group (13.26% ± 8.65%) as compared with the control group (37.98% ± 8.60%) ( P < 0.001). Moreover, 2-point discrimination values were lower in the innervated group (15.11 ± 8.39 mm) when compared with the control group (21.44 ± 7.24 mm) ( P = 0.02). The current perception threshold values for the innervated group were 176.19 ± 31.89, 64.21 ± 19.23, and 42.29 ± 18.96 at 2 kHz, 250 Hz, and 5 Hz, respectively, whereas in the control group, the current perception threshold values were 204.47 ± 36.99, 82.26 ± 27.29, and 58.89 ± 25.38 at 2 kHz, 250 Hz, and 5 Hz ( P = 0.02, P = 0.02, and P = 0.03, respectively)., Conclusion: The innervated vascularized iliac bone flap represents a safe and effective novel approach to preserving lower lip sensation and preventing bone resorption through functional mandibular reconstruction., Clinical Question/level of Evidence: Therapeutic, I., (Copyright © 2024 by the American Society of Plastic Surgeons.)

Objective: This retrospective multicenter study aimed to evaluate surgical versus conservative treatment in patients with hypopharyngeal and laryngeal cancer under real world conditions., Methods: This study included 2307 patients diagnosed with hypopharyngeal or laryngeal squamous cell carcinoma (SCC) in five German tertiary head and neck centers between 01/2004 and 12/2014. Overall, 783 patients with advanced SCC consecutively underwent laryng(opharyng)ectomy (L(P)E). Patient chart data regarding age, sex, tumor location, TNM status, grading, indication for L(P)E, treatment modalities, R status, postoperative complications, and hospitalization time were analyzed. Patients with lacking data and incomplete staging and those who refused treatment or did not comply with the recommended treatment were excluded from survival analysis., Results: A slight but significant increase was observed in L(P)E, referring to an increasing rate of tumor recurrence. While T1/2N0M0 laryngeal and hypopharyngeal cancer patients showed comparable overall survival (OS) for surgical and conservative treatment, surgery showed significantly better OS in lymph node-positive individuals and locally advanced tumor stages. Tumor recurrence occurred in more than one-third of the cases. In particular, in early glottic cancer recurrence, L(P)E represents a curative and safe treatment option, whereas in supraglottic and hypopharyngeal cancer, L(P)E was associated with reduced survival rates. Notably, 36% of patients with supraglottic cancer and 59% of patients with hypopharyngeal cancer recurrence could only be treated with palliative care., Conclusion: Comparable survival rates were demonstrated for cT1/2N0M0 laryngeal and hypopharyngeal SCC compared with primary chemo-/radiotherapy and larynx-preserving surgery. Better OS was achieved after surgery in nodal-positive patients and in those with locally advanced disease. Tumor recurrence should be anticipated in up to 39% of cases. Glottic cancer recurrence can be successfully and safely treated with L(P)E, whereas OS is reduced in hypopharyngeal cancer and possibly in supraglottic cancer., (© 2024. The Author(s).)

Background: This study compares patient-reported functional and aesthetic outcomes of split-thickness skin graft (STSG) versus hatchet flap closure of radial forearm free flap (RFFF) donor site., Methods: Patients with RFFF (2015-2020) were retrospectively identified. Those willing to participate in patient-reported outcomes (PRO) filled out Patient-Observer Scar Assessment Scale (POSAS) and Michigan Hand Outcome Questionnaire (MHOQ)., Results: 198 patients met our inclusion criteria and 81 participated in PRO. There was a higher rate of tendon exposure in STSG versus hatchet flap (11 vs. 1, p = 0.0019), but a lower rate of skin necrosis (5 vs. 16, p = 0.0190) and epidermolysis (1 vs. 12, p = 0.0028). Scar quality in STSG was superior to hatchet flap in all domains of POSAS. MHOQ scores were similar between both groups with no statistical difference in overall scores (p = 0.2165)., Conclusions: STSG appeared to have less compromise in activities of daily living, better satisfaction and improved scar quality than hatchet flap, but a higher rate of tendon exposure., Level of Evidence: 3 Laryngoscope, 134:4266-4273, 2024., (© 2024 The Author(s).

Objectives: To determine the roles of small GTP-binding proteins Rac1, Rac2, and Rac3 expression in pterygial tissue and to compare these expressions with normal conjunctival tissue. Materials and Methods: Seventy-eight patients with primary pterygium were enrolled. Healthy conjunctival graft specimens obtained during pterygium surgery were used as control tissue. The real-time polymerase chain reaction method on the BioMark HD dynamic array system was utilized in genomic mRNA for the gene expression analysis. Protein expressions were analyzed using western blot and immunohistochemical methods. Results: RAC1, RAC2, and RAC3 gene expressions in pterygial tissues were not markedly elevated when compared to the control specimens (p>0.05). As a very low level of RAC1 gene expression was observed, further protein expression analysis was performed for the Rac2 and Rac3 proteins. Western blot and immunohistochemical analysis of Rac2 and Rac3 protein expression revealed no significant differences between pterygial and healthy tissues (p>0.05). Conclusion: This is the first study to identify the contribution of Rac proteins in pterygium. Our results indicate that the small GTP-binding protein Rac may not be involved in pterygium pathogenesis. [ABSTRACT FROM AUTHOR]

Objectives: Review of the current and relevant literature to develop a list of evidence‐based recommendations that can be implemented in head and neck surgical practices. To provide rationale for the multiple aspects of comprehensive care for head and neck surgical patients. To improve postsurgical outcomes for head and neck surgical patients. Methods: Extensive review of the medical literature was performed and relevant studies in both the head and neck surgery and other surgical specialties were considered for inclusion. Results: A total of 18 aspects of perioperative care were included in this review. The literature search included 276 publications considered to be the most relevant and up to date evidence. Each topic is concluded with recommendation grade and quality of evidence for the recommendation. Conclusion: Since it's conception, enhanced recovery after surgery (ERAS) protocols have continued to push for comprehensive and evidence based postsurgical care to improve patient outcomes. Head and neck oncology is one of the newest fields to develop a protocol. Due to the complexity of this patient population and their postsurgical needs, a multidisciplinary approach is needed to facilitate recovery while minimizing complications. Current and future advances in head and neck cancer research will serve to strengthen and add new principles to a comprehensive ERAS protocol. Level of Evidence: 2a.

Head and neck cancer (HNC) treatment is becoming increasingly multidisciplinary, and patient characteristics vary. Therefore, a multidisciplinary tumor board (MTB) is essential in clinical practice. This review provides insights into the benefits and tips for improving head and neck MTB from the perspective of medical oncologists. The MTB is a platform to discuss the optimal application of the standard of care to each case, reach a consensus, and establish a recommendation to support patients' decision-making. A productive and educational MTB also provides an opportunity to share information on ongoing clinical trials with physicians. Case presentations should be systematic to discuss all new and challenging cases before, during, and after the treatment. Human resource development, particularly of head and neck medical oncologists, is crucial. The type of multidisciplinary network between medical staff and the extent of patient intervention differs among MTB teams. Subsequently, a virtual MTB can establish a medical network between institutions that will contribute to the equalization and centralization of head and neck oncologic care. [ABSTRACT FROM AUTHOR]

Management of the neck in oral cavity squamous carcinoma is debatable. There is controversy regarding role of SND in single node positive neck in oral SCC. The aim of this study was to determine the efficacy of selective neck dissection (SND) for cN1 neck in patients with oral cancer. A retrospective chart review of 266 oral cancer patients who were clinically single node positive from August 2013 to December 2019 was done. Patients having clinical or radiological cN1 disease undergoing SND were included. Two hundred sixty-six patients were analysed with 86% male predominance. Median age was 48 years. The commonest primary site was Bucco-alveolar complex (64%). Total of 319 SNDs were done in 266 patients. At median follow-up of 29 months, 29 patients (9%) had neck recurrence among which 4 patients had recurrence at level V, along with recurrence at other nodal levels. Three-year regional control was 86%, while DFS and OS were 66% and 68% respectively. For oral cancer with single clinically node positive neck (cN1), SND is an effective and oncological safe treatment. Outcomes are similar with modified neck dissection reported in the literature.

Objective: Patients with advanced laryngeal cancer are typically presented with divergent treatment options, namely chemoradiation versus total laryngectomy. This study aims to understand general perspectives of the factors involved in this decision‐making process. Methods: Surveys were constructed using specialized conjoint analysis software. Seven attributes integral to the decision‐making process for advanced laryngeal cancer treatment were included. Results: Three hundred one healthy adult volunteers completed the decision‐making program. The relative impact of each treatment attribute on decision making across all participants was scored with an average importance score (standard deviation) as follows: Lifespan 22.2% (±8.5), Voicing 21.4% (±5.9), Swallowing 19.1% (±7.3), Cancer Cure 14.9% (±6.2), Mode of Breathing 11.0% (±3.7), Self‐Image 6.7% (±2.9), and Treatment Type 4.8% (±3.0). Conclusions: General public opinion ranked lifespan, voicing, and swallowing aspects as similarly important, and all were ranked more important than probability of cure. These data demonstrate a variety of priorities among participants and the need for tailored discussions when determining treatment choice for advanced laryngeal cancer. Level of Evidence: Level 4.

Cancer is a major cause of high morbidity and mortality worldwide. Several environmental, genetic and lifestyle factors are associated with the development of cancer in humans and result in suboptimal treatment. The human microbiota has been implicated in the pathophysiological process of cancer and has been used as a diagnostic, prognostic and risk assessment tool in cancer management. Notably, both extratumoural and intratumoural microbiota are important components of the tumor microenvironment, subtly influencing tumorigenesis, progression, treatment and prognosis. The potential oncogenic mechanisms of action of the intratumoural microbiota include induction of DNA damage, influence on cell signaling pathways and impairment of immune responses. Some naturally occurring or genetically engineered microorganisms can specifically accumulate and replicate in tumors and then initiate various anti-tumor programs, ultimately promoting the therapeutic effect of tumor microbiota and reducing the toxic and side effects of conventional tumor treatments, which may be conducive to the pursuit of accurate cancer treatment. In this review, we summarise evidence revealing the impact of the intratumoural microbiota on cancer occurrence and progress and potential therapeutic and diagnostic applications, which may be a promising novel strategy to inhibit tumor development and enhance therapeutic efficacy. -_S9VDnSXDc4mZPdW-8xEX Video Abstract [ABSTRACT FROM AUTHOR]

Objective- To acknowledge patient-perceived voice-related and overall quality of life (QOL) in addition to disability index based on the validated voice-related quality of life survey (VRQOL), WHOQOL-BREF, and WHO DAS II questionnaires in T2 and early T3 laryngeal tumors after definitive radiotherapy. Methods- 35 patients of T2(15) and early T3(20) tumors were enrolled, assessed with three questionnaires of VRQOL, WHOQOL-BREF, and WHO DAS II before the start of radiotherapy, then at 12 and 24 weeks after radiotherapy, and the results were analyzed. Results- All 35 (100%) patients had significant vocal deterioration with a raw VRQOL score of more than 25 at the beginning, which significantly improved at 12 weeks post-radiotherapy (p < 0.5). However, VRQOL scores at the 12th and 24th weeks were statistically insignificant. On comparing the WHOQOL-BREF and WHO DAS II, domains of physical health, psychological health, and participation in society showed significant improvement in both the groups after radiotherapy except distress scores in T2 laryngeal cancers, where pre and post-radiotherapy scores were not significantly different suggesting residual distress. Conclusion- The QOL parameters improve significantly with treatment, however, there exists a persistence of residual distress even at 24 weeks after radiotherapy and hence, routine involvement of clinical psychologists should be emphasized in practice to alleviate anxiety, distress, and concerns regarding disease outcome and recurrence. 12 to 24 weeks post-radiotherapy can be an optimum time to gauge the improvement in the patient-related QOL outcome parameters and does not differ much between these durations.

Aims: This study aimed to develop and evaluate the psychometric properties of the Tamil version of the Eating Assessment Tool (EAT-10). Setting & Study Design: Prospective cross-sectional study on persons with Head and Neck Cancer (HNC) during their follow-up for oncological and swallowing consultation at a tertiary care hospital and healthy individuals recruited from the community. Methods: The study was conducted in two phases: (1) translation and development of the Tamil version of EAT-10 and (2) administration of Tamil EAT-10 to assess internal consistency reliability, test-retest reliability and known-group validity. 92 participants with HNC in the clinical group and 149 healthy adults in the control group completed the Tamil EAT-10. In addition, a subgroup of 20 participants with HNC repeated the questionnaire within a week to assess test-retest reliability. Results: The Cronbach alpha for the 10 items was 0.96 indicating high internal consistency reliability. The test-retest reliability of the individual items and the total scores (r = 0.98) of the Tamil version of EAT-10 were high. The total EAT-10 scores for the HNC group (14.4 ± 11.5) were significantly higher (p < 0.001) than the scores for healthy adults (0.72 ± 2.0). Conclusion: The Tamil version of the EAT-10 developed in this study is a reliable and valid self-administered tool for identifying concerns related to swallowing among persons treated for HNC and healthy adults. This tool can be implemented for clinical practice and research in dysphagia among a Tamil-speaking population. [ABSTRACT FROM AUTHOR]

Introduction: Voice production can be affected in early laryngeal cancer. The purpose of this study was to investigate the correlation between Voice Handicap Index (VHI) and Voice-Related Quality of Life (V-RQOL) among patients with early laryngeal cancer. Methods: Twenty-seven patients with early laryngeal cancer (T1, T2) and a mean age of 59.35 ± 7.77 years who were visited in Amir-Alam hospital, took part in this study. After a diagnosis of early laryngeal cancer by a laryngologist, the patients filled out the Persian versions of the VHI and V-RQOL questionnaires. Results: The results showed the mean total score of VHI and V-RQOL were 65.94 ± 14.21 and 48.64 ± 9.75% in patients with early laryngeal cancer, respectively. These results indicated the total and subscales' scores of VHI increased while the scores of VRQOL decreased. The Pearson correlation between total scores of the VHI and V-RQOL was − 90. Also, there was a negative significant correlation between total and subscales' scores of VH and VRQOL (r Pearson= -0.46 to -0.90, p ≤ 0.05). Conclusion: Our findings demonstrated decreased quality of life related to voice in patients with laryngeal cancer who were in the early stages of tumor growth (T1, T2). Regarding the high negative significant correlation between results of VHI and V-RQOL in patients with early laryngeal cancer, both questionnaires can be used instead of each other for saving time in voice clinics.

Iatrogenic nerve injuries contribute significantly to postoperative morbidity across various surgical disciplines and occur in approximately 500,000 cases annually in the US alone. Currently, there are no clinically adopted means to intraoperatively visualize nerves beyond the surgeon's visual assessment. Here, we report a label-free method for nerve detection using diffuse reflectance spectroscopy (DRS). Starting with an in vivo rat model, fiber- and imaging-based DRS independently identified similar wavelengths that provided optimal contrast for nerve identification with an accuracy of 92%. Optical property measurements of rat and human cadaver tissues verify that the source of contrast between nerve and surrounding tissues is largely due to higher scattering in nerve and differences in oxygenated hemoglobin content. Clinical feasibility was demonstrated in patients undergoing thyroidectomies using both probe-based and imaging-based approaches where the nerve were identified with 91% accuracy. Based on our preliminary results, DRS has the potential to both provide surgeons with a label-free, intraoperative means of nerve visualization and reduce the incidence of iatrogenic nerve injuries along with its detrimental complications.

Solitary fibrous tumour (SFT) is an uncommon soft tissue lesion, and even rarer in the oral cavity, where it presents a similar clinical presentation to other lesions that affect the oral cavity. Due to its broad morphological spectrum, the histopathological diagnosis might be challenging and, for a definite diagnosis, the use of complementary tools is usually required, such as immunohistochemistry. We aimed to report a case of a 31‐year‐old man with an asymptomatic, slightly purplish nodule located on the dorsum of the tongue. The intraoral physical examination revealed the presence of a nodular exophytic lesion and fibrous consistency, measuring 0.9 cm. The histopathological examination revealed a proliferation of mesenchymal cells with variable morphology in a stroma consisting of dense fibrous connective tissue with areas of hyalinization, in addition to numerous vascular structures with a "staghorn‐shaped" appearance. Considering the unspecific histopathological features, we performed the immunohistochemistry technique, which revealed diffuse positivity for CD34, focal positivity for Bcl‐2 and negativity for S100. Therefore, combined clinical, morphological and immunohistochemical features enable the conclusive diagnosis of solitary fibrous tumour. We emphasize the importance of knowledge about the differential diagnosis of undifferentiated lesions that affect the soft tissues to distinguish SFT from other neoplasms and, thus, perform the most appropriate treatment.

There are an estimated 6–10 million smokeless tobacco (Toombak) users in Sudan, the majority being males. Toombak is known to be a carcinogenic product that is likely to modify the oral microbiome spatiality into a high-risk potential for the development and progression of oral cancer, but previous studies are lacking in this field. Here, we endeavour for the first time the exploration of the oral microbiome in key mucosal areas of the oral cavity and assess the microbiome variations in premalignant and oral squamous cell carcinoma (OSCC) samples from both users and non-users of Toombak. 16S rRNA sequencing was performed on DNA obtained from pooled saliva, oral mucosa and supragingival plaque from 78 Sudanese users and non-users of Toombak, aged between 20 and 70 years. In 32 of the pooled saliva samples, the mycobiome (fungal) environment was analysed through ITS sequencing. Then, 46 formalin-fixed paraffin-embedded samples of premalignant and OSCC samples were collected, and their associated microbiomes sequenced. The oral Sudanese microbiome was found to be enriched in Streptococcaceae, but Staphylococcaceae were significantly more abundant amongst Toombak users. Genera enriched in the oral cavity of Toombak users included Corynebacterium_1 and Cardiobacterium while in non-users, Prevotella, Lactobacillus and Bifidobacterium were prominent. Aspergillus was the most abundant fungus in the mouths of Toombak users with a marked loss of Candida. The genus Corynebacterium_1 was abundant in the buccal, floor of the mouth and saliva microbiomes as well as in oral cancer samples from Toombak users indicating a possible role for this genus in the early stages of oral cancer development. An oral cancer microbiome that favours poor survival and metastasis in those who use Toombak also emerged that includes the genera Stenotrophomonas and Schlegelella. Those utilising Toombak carry an altered oral microbiome that may be an additional risk factor for this products carcinogenicity to the oral structures. These significant microbiome modulations are a newly emerging key driving factor in oral cancer development and progression in Toombak users while it is also shown that Toombak users carry an oral cancer microbiome that may increase the potential for a poorer prognosis.

Background: The course of the spinal accessory nerve in the neck is long and superficial rendering it at high risk of injury during procedures performed in the posterior triangle. The majority of spinal accessory nerve injuries are iatrogenic in nature. This is associated with significant morbidity including reduction in shoulder movements, drooping of the shoulder, winging of the scapula and neuropathic pain. Knowledge of the nerve anatomy reduces the risk of intra-operative nerve injury. Traditional teaching describes the point of entry into the posterior triangle as the intersection between the upper and middle third of the posterior border of sternocleidomastoid. The aim of this study was to determine whether this is in fact the case and if so, whether this landmark can reliably be used to identify the spinal accessory nerve in order to improve patient outcomes. Materials and methods: The spinal accessory nerve was identified unilaterally in 26 cadavers. The total length of sternocleidomastoid was measured as well as the length along the posterior border from the inferior aspect of the mastoid process to the point at which the accessory nerve enters the posterior triangle of the neck. These measurements were used to calculate the ratio of the entry point of the nerve into the posterior triangle along the length of the posterior border of sternocleidomastoid from its superior insertion point. The mean ratio was 0.35 with 95% confidence intervals of 0.33 to 0.36. Results and Conclusions: Our findings confirm the traditional description of the entry point of the spinal accessory nerve into the posterior triangle of the neck. We describe a so-called ‘safe zone’ inferior to the midpoint of the posterior border of sternocleidomastoid within which the spinal accessory nerve is unlikely to be found, thereby reducing the risk of iatrogenic injury.

Fanconi anemia (FA) is the most common hereditary bone marrow failure syndrome, with an incidence of 1 in 5,000,000. This disease is caused by an alteration in one of the 23 genes associated with the FA/BRCA DNA repair pathway, which is responsible for repairing interstrand bridges generated during homologous recombination. FA has been associated with a predisposition to other types of neoplasm. The current study aimed to present a pathogenic variant in FANCA observed in three Mexican siblings, as detected by next-generation sequencing (NGS). The results of an induced chromosomal breakage test showed chromosomal breaks and radial figures, which were compatible with FA, and a normal karyotype. NGS TruSight Hereditary Cancer Panel analysis resulted in the FANCA:c.3931_3932delAG variant being classified as pathogenic according to bioinformatics analysis. The present study reports a pathogenic variant in FANCA that was found in a Mexican family with FA, in which one of the siblings exhibited a suggestive mucosa-assisted lymphoid tissue lymphoma, which is an atypical presentation of neoplasia associated with FA.

In surgical procedures where the risk of accidental nerve damage is prevalent, surgeons commonly use electrical stimulation (ES) during intraoperative nerve monitoring (IONM) to assess a nerve's functional integrity. ES, however, is subject to off-target stimulation and stimulation artifacts disguising the true functionality of the specific target and complicating interpretation. Lacking a stimulation artifact and having a higher degree of spatial specificity, infrared neural stimulation (INS) has the potential to improve upon clinical ES for IONM. Here, we present a direct comparison between clinical ES and INS for IONM performance in an in vivo rat model. The sensitivity of INS surpasses that of ES in detecting partial forms of damage while maintaining a comparable specificity and sensitivity to more complete forms. Without loss in performance, INS is readily compatible with existing clinical nerve monitoring systems. These findings underscore the clinical potential of INS to improve IONM and surgical outcomes.

Background: To evaluate treatment modalities of T4 larynx cancer in older adults using SEER‐Medicare. Methods: The database was queried for patients aged 66 and older with nonmetastatic T4 laryngeal squamous cell cancer from 2006 to 2015. Treatment modalities compared were surgery plus chemoradiation (SCR), surgery plus radiation (SR), chemoradiation (CR), surgery (S), and radiation (R). Multivariate analysis and Kaplan–Meier methods were used to explore the relationship of treatment modality and survival. Total cancer‐related costs were calculated. Results: A total of 438 patients met inclusion criteria. Patients receiving CR or SR had similar CSS to SCR (HR 1.36 and HR 1.24, respectively). Those receiving S (HR 2.00) or R (HR 2.41) had significantly worse CSS. Similar findings were observed for OS. Cancer care‐related costs were not significantly different but highest in SCR ($162215) and lowest in R ($121421). Conclusion: Older patients with T4 larynx cancer had similar survival rates when treated with CR, SR, and SCR. Average total health care costs were not significantly different between modalities. Patients not eligible for triple‐modality could consider these other treatment options. [ABSTRACT FROM AUTHOR]

Approximately 30% of patients with head and neck squamous cell carcinoma (HNSCC) are at least 70 years of age, and this percentage is expected to increase as the population increases and lives longer. Elderly patients are underrepresented in head and neck oncology clinical trials, and there is minimal evidence on the management of HNSCC for this population. Subsequently, despite their best intentions, physicians may unknowingly recommend an ill-suited course of therapy, which may result in suboptimal oncological or functional outcomes or adverse events. Surgical approaches have the potential to carry a higher risk of morbidity and mortality in older adults, especially in patients with multiple comorbidities. Definitive radiation therapy treatment in patients with HNSCC frequently involves 7 weeks of daily radiation, sometimes with concurrent chemotherapy, and this demanding treatment can be difficult for older adult patients, which may lead to treatment interruptions, potential removal of concurrent systemic therapy, compromised outcomes, and diminished quality of life. There are clinical trials currently underway investigating altered fractionation regimens and novel, less toxic systemic treatments in this population. This review provides an overview of how best to approach an older adult with HNSCC, from initial work-up to treatment selection. [ABSTRACT FROM AUTHOR]

Objective: Distant metastasis often indicates a poor prognosis, so early screening and diagnosis play a significant role. Our study aims to construct and verify a predictive model based on machine learning (ML) algorithms that can estimate the risk of distant metastasis of newly diagnosed follicular thyroid carcinoma (FTC). Design: This was a retrospective study based on the Surveillance, Epidemiology, and End Results (SEER) database from 2004 to 2015. Patients: A total of 5809 FTC patients were included in the data analysis. Among them, there were 214 (3.68%) cases with distant metastasis. Method: Univariate and multivariate logistic regression (LR) analyses were used to determine independent risk factors. Seven commonly used ML algorithms were applied for predictive model construction. We used the area under the receiver‐operating characteristic (AUROC) curve to select the best ML algorithm. The optimal model was trained through 10‐fold cross‐validation and visualized by SHapley Additive exPlanations (SHAP). Finally, we compared it with the traditional LR method. Results: In terms of predicting distant metastasis, the AUROCs of the seven ML algorithms were 0.746–0.836 in the test set. Among them, the Extreme Gradient Boosting (XGBoost) had the best prediction performance, with an AUROC of 0.836 (95% confidence interval [CI]: 0.775–0.897). After 10‐fold cross‐validation, its predictive power could reach the best [AUROC: 0.855 (95% CI: 0.803–0.906)], which was slightly higher than the classic binary LR model [AUROC: 0.845 (95% CI: 0.818–0.873)]. Conclusions: The XGBoost approach was comparable to the conventional LR method for predicting the risk of distant metastasis for FTC. [ABSTRACT FROM AUTHOR]

Recent evidence has shown that the human microbiome is associated with various diseases, including cancer. The salivary microbiome, fecal microbiome, and circulating microbial DNA in blood plasma have all been used experimentally as diagnostic biomarkers for many types of cancer. The microbiomes present within local tissue, other regions, and tumors themselves have been shown to promote and restrict the development and progression of cancer, most often by affecting cancer cells or the host immune system. These microbes have also been shown to impact the efficacy of various cancer therapies, including radiation, chemotherapy, and immunotherapy. Here, we review the research advances focused on how microbes impact these different facets and why they are important to the clinical care of cancer. It is only by better understanding the roles these microbes play in the diagnosis, development, progression, and treatment of cancer, that we will be able to catch and treat cancer early.

Background: The study's objective is to assess the feasibility and utility of VSP for maxillary reconstruction with the scapular free flap. Methods: An open‐source VSP platform was used to create the reconstruction models and simple guides. Clinical, operative, and postoperative data were collected. Results: Ten patients in the VSP cohort and 18 in the non‐VSP control cohort were included in the study. There was a significant reduction in operative time (256.0 ± 69.4 vs. 448.1 ± 108.2 min, p < 0.01), tracheotomy rate (20% vs. 72%, p < 0.01), increased two‐team utilization rate (80% vs. 0%, p < 0.01) and better reconstructive accuracy (7.5 ± 3.4 vs. 11.7 ± 7.6 mm, p = 0.048) for the VSP cohort. Conclusions: Maxillary reconstruction planned with an in‐house open‐source VSP platform and accompanied simple guides can facilitate a two‐team approach, reduce operative time, and improve structural accuracy. This open‐source technology has great potential to be readily applied in other institutions to improve efficiency and outcomes. [ABSTRACT FROM AUTHOR]

The current study aimed to investigate the effect of periodontitis and long-term heavy metal (HM) exposure on the salivary microbiome. The patients were divided into four groups as Wu Wei control (WWC) group involved healthy individuals, Wu Wei periodontitis (WWP) patients having periodontitis, Jing Chang with metal pollution periodontally healthy individuals (JCP), and Kuang periodontitis (KP). The most abundant bacteria identified at the phylum level in the WWC group were Bacteroides, Firmicutes, and Fusobacteria. Firmicutes were observed in a significantly higher proportion in the KP group than in the WWC, WWP, and JCP. At the genus level, the WWC has major dominating bacterial genera (such as Leptotrichia, Neisseria, and Fusobacterium) which were similar to WWP and KP group. The significant difference (p < 0.05) was found in alpha diversity while in beta diversity, the significant (p = 0.005) results were found among the four groups. The correlation of oral microbiota revealed that HMs present in the soil (Cr, Ni, and Cu) are associated with the growth of Capnocytophaga, Selenomonas, Aggregatibacter, and Campylobacter. The bacterial functions in the KP group were higher in translation and nucleotide metabolism than in the WWP group. This demonstrated that long-term exposure to HMs can influence the salivary microbiota which can alter the functioning, and diversity of bacteria. [ABSTRACT FROM AUTHOR]

Bone defect repair is a continual and complicated process driven by a variety of variables. Because of its bright multicolor luminescence, superior biocompatibility, water dispersibility, and simplicity of synthesis from diverse carbon sources, carbon dots (CDs) have received a lot of interest. It has a broad variety of potential biological uses, including bone defect repair, spinal cord injury, and wound healing. Materials including CDs as the matrix or major component have shown considerable benefits in enabling bone defect healing in recent years. By altering the carbon dots or mixing them with other wound healing-promoting agents or materials, the repair effect may be boosted even further. The report also shows and discusses the use of CDs to heal bone abnormalities. The study first presents the fundamental features of CDs in bone defect healing, then provides CDs manufacturing techniques that should be employed in bone defect repair, and lastly examines their development in the area of bioengineering, particularly in bone defect repair. In this work, we look at how carbon dots and their alteration products may help with bone defect healing by being antibacterial, anti-infective, osteogenic differentiation-promoting, and gene-regulating.

The purpose of this study was to investigate the relationship between oral and dental health in cancer patients and control group, which was conducted in Tabriz Shahid Gazi hospital. A researchers-made and validated questionnaire including oral and dental health criteria, was filled by the cancer patients (201 cases) and healthy controls (199 cases). Then, the results of the study were analyzed by SPSS software, and reported as Odds ratios (95 % confidence intervals) in tow groups. The results indicate that comparison of filled tooth, tooth extraction, dental caries, and gingival problems including bleeding, gum surgery and inflammation in cancer and controls were significantly meaningful. However, the comparison between the two groups was not significant in terms of the type of the tooth (natural or denture) and the number of daily toothbrushes, but they were considered as risk factors due to statistical results. Environmental factors, and especially oral hygiene, can play an important role in the incidence of different cancers. Among these, the type of oral microorganisms, and their overgrowth and released antigens should be studied further in the emergence of different kinds of cancer in humans. [ABSTRACT FROM AUTHOR]

Laryngocele is very uncommon and no consensus regarding its surgical management is yet established. While traditional external approach is still being recommended some suggest a better microlaryngoscopic management assisted by CO2 laser that has gained popularity. Recurrence is better known with conservative surgery but this paper presents a modified single stage endolaryngeal technique for combined laryngoceles to overcome the same. The salient features are (1) A comparatively larger operculum is created and all the visible mucosa is excised; (2) the base of residual postoperative cavity is moistened with cotton soaked with concentrated carbolic acid for 1 min and (3) the residual 'charred' base with intermittent oozing is packed with single layer of surgicel. The reader is further encouraged to see surgical video of entire procedure. [ABSTRACT FROM AUTHOR]
