xlomafota13 shared this article with you from Inoreader Head and Neck Malignant Paragangliomas: Experience from a Single Institution Via ear nose throat Ear Nose Throat J. 2021 Oct 15:1455613211052338. doi: 10.1177/01455613211052338. Online ahead of print. ABSTRACT Objectives: To summarize the clinicopathological and genetic features of malignant paragangliomas in head and neck cancer and to explore the appropriate treatment options for this rare lesion. Methods: Six patients harboring head and neck malignant paraganglioma from Beijing Tongren Hospital were retrospectively reviewed. The clinicopathological char acteristics, gene mutations, and prognosis of these patients were analyzed. Results: Of these 6 patients, 3 were male and 3 were female; 4 patients harbored malignant carotid body tumors, and two had malignant vagal paragangliomas. Three patients had cervical lymph node metastasis, two presented with lung and bone metastasis, and 1 had lung and liver metastasis. Of the 6 patients, four underwent surgical resection, and the other two patients denied surgery and instead received chemotherapy with paclitaxel, ifosfamide, and dacarbazine. These 2 patients with vagal paraganglioma received postoperative radiotherapy. All 6 patients are still alive at the present time, with a median follow-up time of 66 months. Positive Ki-67 expression in tumor tissue ranged from 1% to 40%. Genetic mutations in SDHD, SDHB, ATR, and MAP3K13 were identified in 4 patients. Conclusions: After comprehensive treatment, head and neck malignant paraganglioma can attain a favorable prognosis. Geneti c mutations are commonly detected in patients with malignant paragangliomas. This study also identified mutations in ATR and MAP3K13 in these patients. PMID:34654328 | DOI:10.1177/01455613211052338 View on the web Inoreader. Take back control of your news feed.

xlomafota13 shared this article with you from Inoreader Coblation supraglottoplasty: a ten-year experience in a tertiary referral hospital Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2021 Oct 16. doi: 10.1007/s00405-021-07130-8. Online ahead of print. ABSTRACT PURPOSE: The present study aims to review the outcomes of coblation supraglottoplasty performed for children with different types of laryngomalacia, and we discuss the factors affecting these outcomes. METHODS: We retrospectively reviewed the medical records of laryngomalacia patients admitted to the Otorhinolaryngology Department, Mansoura University, from 2010 to 2020. We examined the patient's demography, symptoms, comorbidities, type of laryngomalacia, oxygen saturation, and final outcomes. RESULTS: Our study included 235 patients; 122 patients responded to medical therapy, while 113 underwent surgical management. There is a significant relation between the types and therapy they underwent (p ≤ 0.001). Larger percentage within type I underwent medical therapy. There is a statistically significant difference between the studied groups regarding age at surgery. On pairwise comparison, patients with type II had the lowest age significantly at the surgery when compared with each other individual group (p ≤ 0.001). On multivariate regression analysis, the presence of comorbid congenital heart disease, neurological comorbidities significantly increased the risk of failure of surgical intervention by 17.32 and 5.803 folds, respectively. CONCLUSIONS: Coblation supraglottoplasty is effective and safe to treat severe laryngomalacia. Different morphological types of laryngomalacia require slight surgical variations of coblation supraglottoplasty. The presence of comorbid congenital heart disease, neurological comorbidities significantly increased the risk of failure of surgical intervention.

Preclinical Implementation of a Steerable, Da Vinci Xi ® Compatible CO2‐Laser Fiber Carrier for Transoral Robotic Surgery (TORS): a Cadaveric Feasibility Study

xlomafota13 shared this article with you from Inoreader Preclinical Implementation of a Steerable, Da Vinci Xi ® Compatible CO2‐Laser Fiber Carrier for Transoral Robotic Surgery (TORS): a Cadaveric Feasibility Study Via The International Journal of Medical Robotics and Computer Assisted Surgery Abstract Introduction Monopolar electrocautery is the most common dissection and coagulation tool during transoral robotic surgery (TORS) but causes significant collateral tissue damage as opposed to CO2 laser. We aimed at combining both modalities in one robotic instrument arm. Methods We developed a steerable CO2-laser fiber carrier serving as an add-on to the existing Endowrist® monopolar spatula of the Da Vinci Xi. Feasibility and safety were assessed in a preclinical setting. Results One radical tonsillectomy with monopolar cautery and 3 with the instrument prototype were performed in 2 cadavers by 2 surgeons. No serious prototype-related intra-operative difficulties were observed. Safe and efficient switching between energy sources proved possible in all simulated intra-operative bleeding events. Prototype use allowed for the identification of the majority of key anatomical structures and was scored favorably on NASA-TLX ques tionnaires. Discussion The reported prototype successfully combines the advantages of CO2-laser with the advantages of TORS. This article is protected by copyright. All rights reserved.

The clinical and financial impact of introducing robotic‐assisted hysterectomy in a tertiary referral center: a direct cost analysis of consecutive hysterectomies during a decade

xlomafota13 shared this article with you from Inoreader The clinical and financial impact of introducing robotic‐assisted hysterectomy in a tertiary referral center: a direct cost analysis of consecutive hysterectomies during a decade Via The International Journal of Medical Robotics and Computer Assisted Surgery Abstract Background Economic data and the clinical impact of introducing robotic-assisted hysterectomy in a European setting are scarce with conflicting findings. Methods In this retrospective cohort study, the cost and complication rate of the different approaches of hysterectomy are investigated, both benign and (pre)malignant indications were included. Results 844 patients were included: 323 (38.3%) patients underwent robotic-assisted hysterectomy (RAH), 317 (37.5%) total abdominal hysterectomy (TAH), and 204 (24.2%) total laparoscopic hysterectomy (TLH). TAH dropped from 67.2% to 25.5% of procedures, whilst RAH rose to 41.8% of cases. The total hospitalization cost was for RAH €5208.39 (± €916.91), for TAH €5846.61 (± €4464.37) and for TLH €3790.06 (± €1267.05). The postoperative complication rate of TAH (9.1%) was significantly higher in comparison with TLH and RAH (5.4% and 3.1% respectively, p=0.005). Conclusions RAH h as replaced TAH in most cases, especially for large uteri, early-stage endometrial cancer and in selected endometriosis cases, resulting in reduced morbidity with lower hospitalization costs. The indications for TLH remained, including menorrhagia, adenomyosis and persistent cervical dysplasia. This article is protected by copyright. All rights reserved. View on the web Inoreader.

Secretory Carcinoma of the Thyroid in a 49-Year-Old Man Treated with Larotrectinib: Protracted Clinical Course of Disease Despite the High-Grade Histologic Features

xlomafota13 shared this article with you from Inoreader Secretory Carcinoma of the Thyroid in a 49-Year-Old Man Treated with Larotrectinib: Protracted Clinical Course of Disease Despite the High-Grade Histologic Features Via radioactive iodine Head Neck Pathol. 2021 Oct 16. doi: 10.1007/s12105-021-01386-6. Online ahead of print. ABSTRACT Secretory carcinoma of the thyroid gland is histologically and genetically similar to its mammary and salivary gland counterparts. Unlike differentiated thyroid carcinomas of follicular cell origin, thyroid SC is not a thyroglobulin-producing tumor and would not be amenable to radioactive iodine therapy. Instead, these carcinomas may respond to targeted therapy with TRK inhibitors, which further emphasizes the importance of their recognition among morphologically similar thyroid entities. Based on eleven cases reported to date, most primary thyroid SC tend to present as locally advanced malignancies and are characterized by frequent recurrences and long-term survival. High-grade histologic features, increased mitotic count and necrosis have been described but their impact on clinical course and outcome remains unclear. We hereby report the case of a primary SC with high-grade features arising in the thyroid of a 49-year-old man, who was treated with Larotrectinib for his second recurrence. The patient achieved a durable response that lasted for 18 months but then he continued to progress and died of disease 181 months after the diagnosis.

Long-term swallowing-related outcomes in oral cancer patients receiving proactive swallowing therapy

xlomafota13 shared this article with you from Inoreader Long-term swallowing-related outcomes in oral cancer patients receiving proactive swallowing therapy Via swallowing exercises Oral Oncol. 2021 Oct 13;122:105569. doi: 10.1016/j.oraloncology.2021.105569. Online ahead of print. ABSTRACT OBJECTIVES: The present study aimed to evaluate the impact of proactive swallowing rehabilitation on swallowing function and quality of life (QoL) in oral cancer patients in the first two years after definitive treatment. MATERIALS AND METHODS: Consecutive adult patients with locally advanced oral cancer who received radical surgery, free flap reconstruction, and adjuv ant radiotherapy were recruited prospectively, to whom proactive swallowing rehabilitation was provided. Body weight (BW); fiberoptic endoscopic evaluation of swallowing (FEES), functional oral intake scale (FOIS), and diet level; 10-item eating assessment tool (EAT-10), and MD Anderson Dysphagia Inventory (MDADI); and adherence at baseline, 1, 3, 6, 12, and 24 months were evaluated. RESULTS: A total of 104 patients were included during May 2018 to July 2020. Compared to the baseline, significant deterioration in BW, FOIS, and MDADI was noted at one month. However, a trend of recovery was observed in FOIS from one month, and in BW and MDADI from three months. A total of 94% patients were free of tube feeding at 12 months but with a diet requiring special preparations or compensation. Safe swallowing could be achieved in approximately 90% of the participants after six months with diet modification or compensatory maneuvers. BW at 18 and 24 months did not differ significantly fr om baseline. CONCLUSION: Proactive swallowing therapy is feasible for patients with locally advanced oral cancer receiving definitive treatments. It facilitates safe oral intake and adequate nutrition. Patients who performed swallowing exercises had a faster and better recovery in swallowing function and swallowing-related QoL.

Elbow Neuropathic Arthropathy MRI

xlomafota13 shared this article with you from Inoreader Elbow Neuropathic Arthropathy MRI Via Neuroradiology Cases A middle aged male with unilateral left elbow pain, deformity, progressive swelling, restricted movement. < /div> This MRI elbow joint shows: Joint effusion, osteolysis involving proximal end of radius as well as ulna, articulating surface of capitulum as well as trochlea. Marked synovial thickening with frond like projections.  Considering unilateral involvement possibility of infectious aetiology like Tubercular arthritis was one possibility would have been dealt with joint fluid aspiration for culture and sensitivity. However, MRI CERVICAL SPINE screening was done with suspicion of neuropathic arthropathy which surprisingly revealed cervical cord syrinx. Here is MRI CERVICAL SPINE of same patient which shows moderate cervical cord syrinx supporting neuropathic arthropathy. So take home note is it is worthy to suspect and rule out conditions like this whenever applicable and possible as it considerably changes the line of management. View on the web Inoreader.

Rice bodies in subdeltoid bursa MRI

xlomafota13 shared this article with you from Inoreader Rice bodies in subdeltoid bursa MRI Via Neuroradiology Cases This MRI shoulder joint shows fluid distended sub deltoid bursa with numerous typical rice bodies. Differentials given are rheumatoid arthritis and tuberculosis. Suggested CBC, ESR, C-reactive protein, RA, anti-CCP in view of RA and joint fluid aspiration for culture and sensitivity in view of Tubercular Arthritis. Rice body effusion or rice bodies in joint effusion or bursa represents an uncommon, nonspecific, inflammatory process, where multiple small loose intra-articular bodies resembling polished grains of white rice.  They are typically seen with Rheumatoid arthritis, Tuberculosis. However it is also known to occur with juvenile arthritis, seronegative arthritis, osteoarthritis, septic joint, trauma and chronic bursitis. They are almost of same size, hypointense on T1 as well as T2 weighted images without enhancement on post contrast, the shape is very typical with tapering ends resembling rice grains. They should be differentiated from synovial chondromatosis where loose bodies are relatively larger in size, rou nd to ovoid in shape and impart slightly high signal on T2-weighted images.

GLI-1 polymorphisms of Hedgehog pathway as novel risk and prognostic biomarkers in melanoma patients

xlomafota13 shared this article with you from Inoreader GLI-1 polymorphisms of Hedgehog pathway as novel risk and prognostic biomarkers in melanoma patients Via Melanoma Research - Published Ahead-of-Print Objective In adult organisms, deregulation of the sonic hedgehog (SHH) signaling pathway is significantly correlated with different malignancies. Currently, data associating genetic polymorphisms in the SHH pathway with melanoma are scarce and largely unknown. The objective of our study was to elucidate an association between gene polymorphisms in the SHH pathway and prognosis of melanoma skin cancer patients. Methods The current study investigated the association of PTCH1 (rs357564), SMO (rs2228617) and GLI1 (rs2228224, rs2228226), polymorphisms with melanoma predisposition and prognosis. Single-nucleotide polymorphisms were assessed by TaqMan SNP Genotyping Assays. The study involved 93 melanoma patients and 97 individuals in the control group. Results Melanoma patients with the variant mutant genotype GG of GLI1 rs2228226 polymorphism had poorer overall survival and recurrence-free survival (P = 0.0001 and P = 0.037, respectively). The multivariate analysis revealed that disease progression [hazard ratio (HR) = 14.434, P = 0.0001] and the GLI1 rs2228226 polymorphism (HR = 4.161, P = 0.006) persisted as independent prognostic factors. Mutated allele carriers (combined heterozygous and mutated genotypes) for GLI1 rs2228224 G and GLI1 rs2228226 G allele significantly increased melanoma risk [odds ratio (OR) = 2.261, P = 0.007; OR = 2.176, P = 0.010]. Conclusion Our study demonstrated that genetic variants in GLI1, downstream member of the HH signaling pathway, are the risk factors for melanoma susceptibility and it can be a novel marker for melanoma prognosis. As a crucial SHH signaling member, GLI1 can also be regarded as a novel drug target for anti-cancer treatment in melanoma. * Marija Dunjic and Nikola Lukic contributed equally to the writing of this article.
