Breast reconstruction is becoming increasingly recognized as a fundamental component in comprehensive breast cancer treatment. The primary goal for any reconstruction is to safely restore a natural appearing breast. When it comes to achieving the elements of size, shape, symmetry, and softness, the use of autologous tissue has many advantages. The approach to autologous breast reconstruction has changed substantia lly over the years as microsurgical free tissue transplants become more routine and accessible. While a variety of flap donor sites exist, careful flap selection based on surgical history and the availability of donor tissue is critical in achieving reliable results. This article reviews the clinical considerations in patient evaluation, donor site selection, and surgical approach taken at the Buncke Clinic.

Free flap harvest will occasionally result in donor-site complications and morbidity. Most of these complications are managed simply without producing lingering effects on activities of daily living. However, some patients will sustain limb weakness, gait issues, chronic pain, and nonhealing wounds. Frank preoperative discussion between surgeon and patient is essential to maximize postoperative outcome and manage expectations. Fast idious surgical technique will help minimize the risks of hematoma, seroma, and infection, while newer techniques can help prevent some issues with wound healing, limb weakness, and sensory changes. In this article, we describe the rates of common and rare complications at free flap donor sites, as well as techniques to prevent and manage them.

Oral functioning after open versus closed treatment of unilateral condylar neck or base fractures: a two‐center controlled clinical trial

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Background

Oral functioning and rehabilitation in patients after condylar trauma can be measured by objective functional outcomes and patient-reported outcomes. The similarities or differences between these outcomes may contribute to the decision if open treatment (OT) or closed treatment (CT) will obtain the most advantageous results.

Objectives

The aim of this study was to compare OT versus CT for unilateral condylar mandibular neck or base fractures in a two-center controlled clinical trial by objective functional outcomes and patient-reported outcomes measured at six weeks and six months follow-up. Additionally, these outcomes were compared within each group.

Methods

Patients were enrolled between January 2017 and November 2019. In one center patients received OT by extra-oral open reduction and internal fixation. In another center patients received CT by maxillomandibular fixation. Objective measurements included the mixing ability test (MAT) and mandibular active range of motion (ROM). Patient-reported outcomes included the mandibular function impairment questionnaire (MFIQ) and visual analogue scale (VAS) for pain. Independent t-tests and Mann-Whitney U tests were used to determine differences between the treatment groups at six weeks and six months follow-up. Paired t-tests and Wilcoxon Signed Rank tests were used to determine differences within each group.

Results

Thirty-three patients were enrolled. No differences were found between the groups treated with OT or CT for MAT, ROM, MFIQ and VAS. Both groups showed functional improvement.

Conclusion

Good objective functional outcomes and patient-reported outcomes were achieved with both OT and CT in patients with unilateral condylar mandibular neck or base fractures.

Feasibility of ipsilateral elective neck irradiation of levels Ib and II without level III in patients with node‐negative sinonasal squamous cell carcinoma

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Background

The necessity of level III irradiation in patients with node-negative advanced sinonasal squamous cell carcinoma (SNSCC) is unclear.

Methods

Seventy-eight patients with advanced SNSCC were included. Survival rates were estimated and compared between treatment groups.

Results

Twenty-five patients received ipsilateral levels Ib and II irradiation (group 1) and 53 patients received ipsilateral levels Ib and II plus level III irradiation (group 2). The median follow-up time was 75.56 months. Five-year survival rates (regional relapse-free survival, overall survival, local relapse-free survival, and distant metastasis-free survival) were similar between groups 1 and 2 (all p > 0.05). Irradiation doses to the thyroid and larynx were significantly lower in group 1 than in group 2.

Conclusions

Ipsilateral irradiation of levels Ib and II neck provides similar regional control and results as irradiation of these levels plus level III, with lower irradiation doses to normal neck tissue, in patients with node-negative advanced SNSCC.

Acoustic Screening of the “Wet voice”: Proof of Concept in an ex vivo Canine Laryngeal Model

alexandrossfakianakis shared this article with you from Inoreader
Acoustic Screening of the

In canine laryngeal model, we found that several acoustic parameters could predict presence of material on the vocal folds, and identified a possible acoustic biomarker of swallowing dysfunction.


Background

Current protocols for bedside swallow evaluation have high rates of false negative results. Though experts are not consistently able to screen for aspiration risk by assessing vocal quality, there is emerging evidence that vocal acoustic parameters are significantly different in patients at risk of aspiration. Herein, we aimed to determine whether the presence of material on the vocal folds in an excised canine laryngeal model may have an impact on acoustic and aerodynamic measures.

Methods

Two ex vivo canine larynges were tested. Three liquids of different viscosities (1:100 diluted glycerin, pure glycerin, and honey-thick Varibar) were placed on the vocal folds at a constant volume. Acoustic and aerodynamic measures were obtained in both adducted and abducted vocal fold configurations. Intraglottal high-speed imaging was used to approximate the maximum divergence angle of the larynges in the studied conditions and examine its relationship to vocal efficiency (VE) and acoustic measures.

Results

In glottic insufficiency conditions only, we found that several acoustic parameters could predict the presence of material on the vocal folds. Based on the combination of the aerodynamic and acoustic data, we found that decreased spectral energy in the higher harmonics was associated with decreased VE in the presence of material on the vocal folds and/or glottic insufficiency.

Conclusion

Decreased spectral energy in the higher harmonics of the voice was found to be a potential biomarker of swallowing dysfunction, as it correlates with decreased vocal efficiency due to material on the vocal folds and/or glottic insufficiency, both of which are known risk factors for aspiration.

Ghost Cell Odontogenic Carcinoma: A Case Report and Literature Review


Ghost cell odontogenic carcinoma (GCOC) is an exceptionally rare malignant odontogenic neoplasm with a significant potential for aggressive growth. Although the literature on this tumor is limited, its high recurrence rates suggest that early and multimodal intervention may be beneficial. This study reports a case of GCOC of the mandible that was successfully treated with surgical resection, reconstruction, and radiation. A comprehensive literature review was performed, and the relevant genomic and histopathological characteristics of this malignancy were determined. Laryngoscope, 2022

Comparison of Transnasal Esophagoscopy and Sedated Esophagogastroduodenoscopy in the Assessment of Laryngopharyngeal Reflux

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Objective

Transnasal esophagoscopy (TNE) in the awake patient and esophagogastroduodenoscopy (EGD) in sedation are both used in the assessment of laryngopharyngeal reflux (LPR). The objective of this study was to compare these two endoscopic methods in contributing to the diagnosis of LPR.

Methods

This study included 54 patients presenting with signs and symptoms suspicious for LPR, which were examined both by TNE and EGD. The contribution of each method to the diagnosis of LPR was evaluated separately and then compared with each other.

Results

In detecting LPR, TNE showed a significant higher sensitivity (94% vs. 60%) and accuracy (93% vs. 59%) than EGD, but their specificity was equal (50% each). The most common pathologic findings in both methods were a hiatal hernia (70% vs 48%) and gaping cardia (69% vs 24%), followed by peptic esophagitis (41% vs 24%).

Conclusion

The value of EGD is limited in the workup of LPR, as sedation tends to mask the subtle findings in this kind of reflux disease.

The maximum phonation time as marker for voice treatment efficacy: a network meta‐analysis

alexandrossfakianakis shared this article with you from Inoreader

ABSTRACT

Purpose

There is a diversity in treatment approaches for voice therapy in which aerodynamic treatment effects between the approaches are lacking. The evidence of voice treatments on the maximum phonation time (MPT) was quantified using the statistical approach of a network meta-analysis (NMA).

Data sources

Three databases and manual search from inception to November 2021 were evaluated.

Study selection

Studies were considered which were reports of randomized controlled/clinical trials (RCT) evaluating the efficacy of a specific voice therapy treatment using MPT as an outcome measure in adult participants with voice disorders. Studies were excluded if participants had been diagnosed with neurological-motor-speech disorders or who were vocally healthy. Furthermore, no medical, pharmacological, or technical instrumental treatments were used.

Data Extraction and Synthesis

Preferred Reporting Items for Systematic Reviews and Meta-analyses Extension Statement guidelines were followed. Two reviewers independently screened citations, extracted data and assessed risk of bias using PEDro scale. Random effects model was used for meta-analysis.

Results

We identified finally 12 RCT studies (treatment groups n=285, and control group without an intervention n=62). Eight interventions were evaluated. The only effective intervention with a significant effect was Vocal Function Exercises (VFE) (mean pre-post difference 6.16 sec, 95% confidence interval, 1.18 sec to 11.13 sec).

Conclusions and Relevance

VFE effectively improved MPT from pre- to post-treatment in comparison with other voice interventions which were identified in the present NMA. Further high-quality intervention studies with large samples sizes, multidimensional measures, and homogeneous groups of dysphonia are needed to support evidence-based practice in laryngology.

Efficacy of prophylactic preoperative desmopressin administration during functional endoscopic sinus surgery for chronic rhinosinusitis: a systematic review and meta‐analysis of randomized placebo‐controlled trials

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Aim

To conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) that examined the efficacy of prophylactic desmopressin versus placebo among patients undergoing functional endoscopic sinus surgery (FESS).

Methods

The Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Embase, Scopus, and Web of Science databases were screened from inception until 18-March-2022. The included studies were evaluated for risk of bias. The efficacy endpoints were summarized as risk ratio (RR) or mean difference (MD) with 95% confidence interval (CI).

Results

Five RCTs comprising 380 patients (desmopressin=191 patients and placebo=189 patients) were included. Collectively, the included RCTs had an overall low risk of bias. The pooled results showed that the mean intraoperative blood loss (n=5 RCTs, MD=–37.97 ml, 95% CI [–56.97, –18.96], p<0.001), 5-point Boezaart scores (n=2 RCTs, MD=–0.97, 95 CI [–1.21, –0.74], p<0.001), and 10-point Boezaart scores (n=2 RCTs, MD= –3.00, 95% CI [-3.61, -2.40], p<0.001) were significantly reduced in favor of the desmopressin group compared with the placebo group. Operation time did not significantly differ between both groups (n=5 RCTs, MD=–3.73 min, 95% CI [–14.65, 7.18], p=0.50). No patient in both groups developed symptomatic hyponatremia (n=3 RCTs, 194 patients) or thromboembolic events (n=2 RCTs, 150 patients)

Conclusion

Among patients undergoing FESS, prophylactic administration of desmopressin does not correlate with significant clinical benefits. Data on safety is limited. Future research may explore the synergistic antihemorrhagic efficacy and safety of tranexamic acid (TXA) plus desmopressin versus TXA alone among patients undergoing FESS.

higher female risk for adult glioma associated with variants in the region of CCDC26

alexandrossfakianakis shared this article with you from Inoreader
Abstract
Background
Glioma accounts for approximately 80% of malignant adult brain cancer and its most common subtype, glioblastoma, has one of the lowest 5-year cancer survivals. Fifty risk-associated variants within 34 glioma genetic risk regions have been found by genome-wide association studies (GWAS) with a sex difference reported for 8q24.21 region. We conducted an Australian GWAS by glioma subtype and sex.
Methods
We analysed genome-wide data from the Australian Genomics and Clinical Outcomes of Glioma (AGOG) consortium for 7,573,692 single nucleotide polymorphisms (SNPs) for 560 glioma cases and 2,237 controls of European ancestry. Cases were classified as glioblastoma, non-glioblastoma, astrocytoma or oligodendroglioma Logistic regression analysis was used to assess the associations of SNPs with glioma risk by subtype and by sex.
Results
We replicated the previously reported glioma risk associations in the regions of 2 q33.3 C2orf80, 2q37.3 D2HGDH, 5p15.33 TERT, 7p11.2 EGFR, 8q24.21 CCDC26, 9p21.3 CDKN2BAS, 11q21 MAML2, 11q23.3 PHLDB1, 15q24.2 ETFA, 16p13.3 RHBDF1, 16p13.3 LMF1, 17p13.1 TP53, 20q13.33 RTEL and 20q13.33 GMEB2 (P<0.05). We also replicated the previously reported sex difference at 8q24.21 CCDC26 (P=0.0024) with the association being nominally significan t for both sexes (P<0.05).
Conclusions
Our study supports a stronger female risk association for the region 8q24.21 CCDC26 and highlights the importance of analysing glioma GWAS by sex. A better understanding of sex differences could provide biological insight into the cause of glioma with implications for prevention, risk prediction and treatment.
