ABSTRACT

Objective: To evaluate the clinical efficacy of topical nasal Pomegranate Fruit Extract (PFE) for Chronic Rhinitis (CR), Chronic Rhinosinusitis with Nasal Polyposis (CRSwNP), and Chronic Rhinosinusitis without Nasal Polyposis (CRSsNP). Methods: Prospective, double-blinded, randomized study including 111 consecutive patients, between April 2012 and Ja nuary 2017, afflicted by CRSwNP, CRSsNP, and CR. Patients from each group were randomly assigned to either PFE treatment or placebo twice daily for 30 days. Therapeutic efficacy was assessed by Ear Nose and Throat, blood and tomographic examinations, and the SNOT-20 questionnaire. Results: CR patients treated with PFE suffered significantly less from thick nasal discharge, difficulty falling asleep, reduced productivity, reduced concentration, and sadness (P = .004, P = .02, P = .03, P = .007 and P = .02, respectively). Conclusions: Topical nasal PFE was found to have some benefits for CR patients, however, not for CRS with or without Nasal Polyposis.

xlomafota13 shared this article with you from Inoreader

J Surg Case Rep. 2021 Sep 8;2021(9):rjab379. doi: 10.1093/jscr/rjab379. eCollection 2021 Sep.

ABSTRACT

Pseudoaneurysm of the superficial temporal artery (STA) is a rare entity that has been reported in the literature after trauma or iatrogenic injuries. We describe a unique case of STA pseudoaneurysm rupture and the clinical sequelae associated with its rupture. We report a case of pseudoaneurysm rupture of the STA that occurred 14 days after craniotomy for cerebrospinal fluid leak repair. We also review the literature, diagnosis and treatment of external carotid artery aneurysms. Rupture of a STA pseudoaneurysm is a previously unreported and serious complication that must be quickly recognized in order to control hemorrhage that may have life threatening complications.

Ear Nose Throat J. 2021 Sep 24:1455613211045566. doi: 10.1177/01455613211045566. Online ahead of print.

ABSTRACT

Metastatic parapharyngeal lymph nodes (LNs) from papillary thyroid carcinomas (PTC) are uncommon and can easily remain undetected. We describe a case that involves a 62-year-old woman treated for a PTC, who presented a rise in serum thyroglobulin (TG) levels. A computed tomography scan was performed, and revealed metastatic nodes in the left parapharyngeal space (P PS). A surgical resection of the nodes was performed with external cervical approach. A histological exam confirmed the diagnosis of a metastatic LN of a PTC. The aim of this report is to emphasize on the possibility of parapharyngeal metastatic nodes in PTC and to describe the diagnosis methods, treatment options, and impact on the prognosis.

xlomafota13 shared this article with you from Inoreader

Eur Arch Otorhinolaryngol. 2021 Sep 24. doi: 10.1007/s00405-021-07096-7. Online ahead of print.

ABSTRACT

OBJECTIVE: Postoperative comfort of the patients undergoing rhinoplasty might be poor because of edema and ecchymosis caused by lateral osteotomy. In this animal experiment, we aimed at performing a quantitative assessment of effects of hyaluronic acid usage on healing process of lateral osteotomy.

METHODS: Fourteen New Zealand rabbits with a weight of 2000-2500 kg and an age of 8-12 weeks were included. Under anesthesia, nasal dorsums were exposed with midline incision and lateral osteotomies on both sides were performed using a 2 mm chisel. A hyaluronic acid-based mesh (Hyalonect®) (1 × 1 cm) was embedded on the left osteotomy areas of all rabbits. Right osteotomy areas were left blank as control group. Collagen density and capillary development were quantitatively compared.

RESULTS: Convergence of fractur e lines was observed in 6 (60%) of 10 samples from Hyalonect® group, while was observed in 4 (40%) of 10 samples from control group. Although a higher rate of convergence was seen in the Hyalonect® group (60% vs 40%), the difference was not statistically significant (p = 0.5). Median collagen score was 2 (1-3) in the Hyalonect® group and 1 (1-2) in the control group. Median capillary count value was 4 (1-23) in the Hyalonect® group and 3 (1-17) in the control group. Both collagen score and capillary count values were significantly greater in the in the Hyalonect® group compared with the control group (p = 0.023 and p = 0.019, respectively).

CONCLUSION: The effects of hyaluronic acid-based meshes on the bone healing process of the lateral osteotomy area might be investigated furthermore, on more comprehensive studies, as a material facilitating collagen organization and capillary development.

Growth After Adenotonsillectomy for Obstructive Sleep Apnea: Revisited

xlomafota13 shared this article with you from Inoreader

Objectives/Hypothesis

To reanalyze the growth trajectory and assess longitudinal changes of children undergoing adenotonsillectomy (AT) versus watchful waiting (WW) enrolled in the Childhood Adenotonsillectomy Trial (CHAT) study and to determine if an AT increases the risk of obesity in children.

Study Design

Reanalysis of prospective cohort investigation.

Methods

The study analyzed publicly available data from CHAT, including 3 months visit data not previously included in a prior publication. Statistical comparisons and mixed-effects modeling were done using age- and sex-specific BMI expressed as a percentage of the 95th percentile (%BMIp95). P < .05 was considered significant.

Results

Children in the AT group, especially if underweight at baseline, had an increased rate of weight gain, with 100% of underweight children in the AT group becoming normal weight compared to 20% for WW. However, the rate of weight gain, as measured by the %BMIp95 trajectory for both AT and WW groups, was not significantly different when baseline weight status and obstructive sleep apnea (OSA) resolution were accounted for. Comparisons of %BMIp95 between treatment groups at baseline, 3- and 7-month follow-up visits also failed to identify statistically significant differences (P > .05). Overall for the entire cohort, resolution of OSA was associated with a decreased weight trajectory (P < .001).

Conclusions

AT compared to WW is not associated with an increased risk of excessive weight gain. Otolaryngologists should be aware of this updated analysis when discussing AT surgical outcomes with families.

Trends in Adjuvant Therapy After Surgery for Oropharyngeal Squamous Cell Carcinoma

xlomafota13 shared this article with you from Inoreader

Objectives/Hypothesis

We aim to 1) evaluate trends in adjuvant treatment of human papilloma virus (HPV)-related oropharyngeal cancer; 2) assess change in complications and functional outcomes over time; and 3) assess change in overall and disease-free survival (DFS) over time.

Study Design

Retrospective analysis.

Methods

Charts of patients who underwent transoral robotic surgery for HPV-related oropharyngeal cancer between 2011 and 2019 were reviewed. Trend analysis was used to compare rate of adjuvant treatment over time. The Kaplan–Meier method was conducted to analyze overall survival (OS) and DFS.

Results

Three hundred and forty-two patients met inclusion criteria. One hundred and sixty-three (47.7%) patients underwent adjuvant radiation, and 90 (26.3%) patients underwent adjuvant chemoradiation. Rate of extranodular extension decreased significantly from 38.9% to 24.0% (P = .004). Rate of adjuvant therapy decreased significantly from 90.9% to 62.5% between 2011 and 2019 (P = .001). In patients who received adjuvant treatment, rate of adjuvant chemoradiation therapy decreased significantly from 40.0% to 20.0% (P < .0005). There was a decrease in rate of 1-year gastrostomy tube dependence in patients treated in 2015 to 2019 versus 2011 to 2014 (2.2% vs. 7.1%, P = .025). In 2011 to 2014, 2-year OS and DFS were 96% and 89%, respectively; in 2015 to 2019, 2-year OS and DFS were 96% and 94%, respectively. There was no difference in OS or DFS between the two time periods.

Conclusions

The rate of adjuvant therapy, particularly chemotherapy, has decreased over time. One-year gastrostomy tube dependence rate has decreased significantly from 2011 to 2014 to 2015 to 2019. There was no change in OS and DFS over this time period.

Alternate dosage formulations of oral targeted anticancer agents

xlomafota13 shared this article with you from Inoreader

J Oncol Pharm Pract. 2021 Sep 24:10781552211037976. doi: 10.1177/10781552211037976. Online ahead of print.

ABSTRACT

OBJECTIVE: Oral anticancer therapies have demonstrated superior outcomes compared to traditional cytotoxic chemotherapy in many disease states. However, certain patients may not be candidates for these agents due to odynphagia or dysphagia. The purpose of this review is to summarize the data for extemporaneous compounding of oral anticancer agents.

DATA SOURCES: Food and drug administration approvals of oncology agents were reviewed to identify oral anticancer therapies. In order to find alternative administration options: the package inserts of each of these agents were reviewed, each medication was searched in a tertiary drug information resource, the medical information teams of each drug manufacturer were contacted to inquire about proprietary data, sites with pediatric trials were contacted, a primary literature searc h was performed, and listservs for national pharmacy and oncology organizations were reviewed.

DATA SUMMARY: Eighty-five food and drug administration-approved oral anticancer therapies were identified to be included. Of those agents, nine (11%), had information in the package insert related to alternative administration. After further research, 46 (54%) of the agents had some information related to alternate formulations for administration. The recipes and stability of each of these compounds is included.

CONCLUSIONS: The majority of agents do not have Phase I or II trials that assess safety or pharmacokinetics of alternative formulations. Clinicians should exercise caution when recommending or administering these agents outside of food and drug administration-approved indicated use and utilize clinical judgment in assessing the risks and benefits of altering anticancer compounds. However, the alternative administration considerations presented can increase access to onc ology patients who have difficulty swallowing.

Clinical predictors of internal carotid artery blowout in patients with radiated nasopharyngeal carcinoma

xlomafota13 shared this article with you from Inoreader

Abstract

Background

The primary objective is to identify clinical predictors of internal carotid artery (ICA) blowout in radiated nasopharyngeal carcinoma (NPC).

Methods

Seventeen ICA blowouts, 14 external carotid artery (ECA) bleeds, and 60 controls were identified from January 1, 2007 to July 31, 2020. Multinomial logistic regression was performed to identify features predictive of ICA blowouts.

Results

Headache was significantly more common among ICA blowouts than ECA bleeds and controls (58.8% vs. 7.1% vs. 6.7%, p < 0.001). The petrous skull base and sphenoid sinus lateral wall was eroded in all petrous and cavernous segment blowouts, respectively. Nasoendoscopy showing exposed clivus (OR 20.5, 95%CI 1.3–324.2) and computed tomography demonstrating skull base erosion (OR 17.8, 95%CI 1.0–311.0) were significantly associated with ICA blowouts compared to controls.

Conclusions

Findings of headache and skull base erosion on nasoendoscopy or imaging during NPC surveillance warrants prophylactic intervention to avoid an ICA blowout.

ABSTRACT

OBJECTIVES: This study aimed to investigate the perilymph metabolism by analyzing the 3D real IR MR findings in acoustic neuroma (AN) after intravenous administration of gadolinium (Gd).

METHODS: Eleven patients (6 men and 5 women) diagnosed with AN were included, and 3D real IR MRI was performed 4 hours after intravenous Gd injection. The signal intensity a nd details of inner ear, tumor, and internal auditory canal (IAC) by MRI were analyzed.

RESULTS: Four patients had tumors confined to the IAC, and 5 had tumors that extended to the cerebellopontine angle cistern. The signal intensity of the cochlea, vestibule, and IAC fundus was conspicuously enhanced in 3D real IR images than the control side. One patient had a tumor in the cochlea, in which the signal intensity of the semicircular canal and vestibule was increased. One patient had an intravestibular tumor in which the signal intensity of the semicircular canal was increased and the cochlea had endolymphatic hydrops in the affected ear.

CONCLUSIONS: The synchronously increased signal intensity in the inner ear and IAC may indicate that IAC may serve as a channel for removal of the perilymph in the inner ear; the blockage by the tumor may have changed the hydrodynamics of the perilymph to cause a longer retention of Gd in the inner ear.

Acta Histochem. 2021 Sep 21;123(7):151789. doi: 10.1016/j.acthis.2021.151789. Online ahead of print.

ABSTRACT

OBJECTIVES: The mechanisms underlying the role of mast cells in wound healing have not been thoroughly studied, and even fewer data are available on studies related to mast cells in the skin of patients with type 2 diabetes mellitus (T2DM). Therefore, this study aims to explore the transcriptional characteristics of mast cells at the single-cell level in patients wit h T2DM and provide experimental data for studying mast cell behaviors under abnormal glucose metabolism.

METHODS: Two patients with T2DM and one trauma patient without diabetes were enrolled. Samples were derived from skin tissue resected at the time of surgery and were isolated by single cell capture technology on BD platform to prepare single cell cDNA library. Seurat was used to process raw reads and analyze data downstream of single-cell RNA sequencing, including removal of low-quality cells, identification of cell clusters at the single-cell level, and screening for differential genes with fold change > 1.5 and p < 0.05 by two-sided t-test. We performed single-cell RNA sequencing on skin tissues of T2DM patients and non-diabetics and identified the cell cluster of skin, single-cell subsets, and transcriptional characteristics of mast cells at a single-cell level. Meanwhile, gene set enrichment(GSEA) analysis was performed on the differentially expressed genes.

RESULTS: A total of 8888 cells were obtained from skin tissue. Clustering analysis revealed eight-cell clusters, identified as smooth muscle cells, dendritic cells, mast cells, and T cells, respectively. Cluster 6 was identified as mast cells with the marker genes TPSAB1, CPA3, TPSB2, MS4A2,KIT, etc., which accounting for 2.7% of the total cell number.Compared with the control group, the genes highly expressed in MCs from T2DM patients, include ADH1C, PAXIP1, HAS1, ARG1, etc., and the low expression genes include PHACTR2, GGA1, RASSF2, etc. GSEA analysis suggested that the signal pathways of MCS in T2DM patients included VEGF signaling pathway, Fc gamma R-mediated phagocytosis, the B cell receptor signaling pathway, natural killer cell-mediated cytotoxicity.

CONCLUSIONS: The characteristic genes of MCs in the skin tissues of T2DM patients were described at the single-cell level. These genes and enriched signaling pathways provide a theoretical basis and data support for furth er researches on dermatopathy in patients with diabetes mellitus.

xlomafota13 shared this article with you from Inoreader

Bull Cancer. 2021 Sep 21:S0007-4551(21)00299-X. doi: 10.1016/j.bulcan.2021.05.008. Online ahead of print.

ABSTRACT

We are taking advantage of the launch of the latest version (v4.6) of our web-based data mining tool "breast cancer gene-expression miner" (bc-GenExMiner) to take stock of its position within the oncology research landscape and to present an activity report ten years after its establishment (http://bcgenex.ico.unicancer.fr). bc-GenExMiner is an open-access, user-friendly tool for statistical mining on breast tumor transcriptomes, annotated with more than 20 clinicopathologic and molecular characteristics. The database comprises more than 16,000 patients from 64 cohorts - including TCGA, METABRIC and SCAN-B - for whom several thousands of genes have been quantified by microarrays or RNA-seq. Correlation, expression and prognostic analyses are available for targeted, exhaustive or customized explorations of queried genes. bc -GenExMiner facilitates the validation, investigation, and prioritization of discoveries and hypotheses on genes of interest. It allows users to analyse large databases, create data visualizations, and obtain robust statistical analysis, thereby accelerating biomarker discovery. Ten years after its launch, judging by the number of visits, analyses, and scientific citations of bc-GenExMiner, we conclude that this web resource serves its purpose in the international scientific community working in breast cancer research, with a never-ending rise in its use.
