Online ahead of print. ABSTRACT Objectives: We evaluated the closure rate after fat-graft myringoplasty (FGM) of perforations differing in size and location. We explored whether patient's factors and the FGM surgical technique influenced surgical outcomes. Methods: We retrospectively studied patients with tympanic membrane perforations who underwent FGM from March 2015 to March 2019 . All procedures were performed by a single senior surgeon at our tertiary hospital. The patients who followed-up for at least 6 months after surgery were enrolled. We recorded hypertension and diabetes status, age, any prior ear surgery, any calcific plaques adjacent to the perforation, and perforation size and location. Results: A total of 150 patients were enrolled. Our success rate of FGM was 90%. Hypertension, diabetes, prior ear surgery history, and eardrum calcific plaques did not affect the surgical outcomes. There was no statistical difference in the surgical success rate according to the size (< 50%) or location of perforation. The closure rate was 97.2% in patients aged 1660 and 87.5% in patients aged > 60, respectively. However, FGM was successful in only two of six children (33.3%) aged ≤ 15 years, thus significantly less than in the other groups. Conclusion: FGM is a fast, safe, and efficient method for repairing tympanic membrane perforation. The surgical outcome is not significantly affected by underlying disease, perforation size or location, or by the condition of the tympanic membrane or older age. However, it may be poor in children with dysfunctional Eustachian tube. PMID:34881650 | DOI:10.1177/01455613211063243 View on the web Inoreader. Take back control of your news feed.

Transoral Endoscopic Thyroidectomy by Vestibular Approach for Differentiated Thyroid Cancer Intraoperatively Invading Strap Muscle

xlomafota13 shared this article with you from Inoreader Transoral Endoscopic Thyroidectomy by Vestibular Approach for Differentiated Thyroid Cancer Intraoperatively Invading Strap Muscle Via radioactive iodine Surg Laparosc Endosc Percutan Tech. 2021 Dec 9. doi: 10.1097/SLE.0000000000001020. Online ahead of print. ABSTRACT BACKGROUND: Transoral endoscopic thyroidectomy vestibular approach (TOETVA) has become increasingly popular in the surgical treatment of thyroid cancer. However, its application in T3b disease has not been well-defined. METHODS: We conducted a quasi-experimental study on patients with an intraoperative diagnosis of T3bN0M0 differentiated thyroid carcinoma from Ja nuary 2019 to January 2021 in our institution. Surgical and early oncological outcomes were assessed. RESULTS: Among 326 patients who underwent TOETVA for thyroid cancer, 12 cases had T3bN0M0 disease intraoperatively. The mean operation time was 136.67±7.32 minutes, with 7.17±0.83 mL of blood loss. No patients reported symptoms of postoperatively transient hypoparathyroidism, mental nerve, or recurrent laryngeal nerve injury. After radioactive iodine therapy, all patients had undetectable thyroglobulin, negative antithyroglobulin, and normal neck ultrasound. CONCLUSIONS: TOETVA seems to be a surgically and oncological safe method for differentiated thyroid cancer patients with small tumors invading strap muscle intraoperatively. The patients can be well-managed with endoscopic total thyroidectomy and postoperative radioactive iodine therapy. Further studies with a larger sample size and longer follow-up are needed to provide more solid evidence. PMID:34882614 | DOI:10.1097/SLE.0000000000001020 View on the web Inoreader.

Cerebrospinal fluid leak as a driving factor in chronic subdural hematoma formation: A histological study

xlomafota13 shared this article with you from Inoreader Cerebrospinal fluid leak as a driving factor in chronic subdural hematoma formation: A histological study Via leak of cerebrospinal fluid Surg Neurol Int. 2021 Nov 23;12:578. doi: 10.25259/SNI_950_2021. eCollection 2021. ABSTRACT BACKGROUND: Chronic subdural hematoma (CSDH) represents the most common neurosurgical disease. Given the demographic shift toward an aging population, the overall incidence of this condition is increasing. Nevertheless, clarity in the pathophysiological process is yet to be made. Several etiological mechanisms have been proposed to initiate and consequently promote fluid collection in the subdural space. Traumatic injury of the bridging veins has long been considered the primum movens of the pathology but increasing evidence shows that trauma is not the only factor involved. Along with recent advances we sought to understand the role of the cerebrospinal fluid (CSF) in the buildup of the intense inflammatory reaction that characterizes CSDH. METHODS: In the present study, we examined histological features of reactive membranes secondary to extrac ranial CSF leakage with CSDH-related membranes. Similarity and differences between the specimens were examined by means of light microscopy. RESULTS: Histological similarities were consistently found between CSDH membranes and reactive membranes secondary to CSF leakage in the extracranial space. Activated histiocytes were highlighted in all specimens along with an intense inflammatory reaction. CONCLUSION: CSDH is most likely the result of a complex interaction among different pathophysiological events resulting from both traumatic and inflammatory etiologies. In the present work, we highlight how CSF leakage could be an early factor that leads to a cascade of events that culminates in CSDH formation.

xlomafota13 shared this article with you from Inoreader New insights into the functions of progesterone receptor (PR) isoforms and progesterone signaling Via American Journal of Cancer Research Am J Cancer Res. 2021 Nov 15;11(11):5214-5232. eCollection 2021. ABSTRACT Progesterone, the ovarian steroid hormone, regulates a plentitude of biological processes in tissues ranging from the brain to bones. Recognizing the role of progesterone and its receptors in physiological processes and maladies can prevent and treat various diseases. Apart from its physiological functions, its role in developing diseases, especially breast cancer, is a recent topic of deliberation. There exists conflicting experimental and epidemiological evidence linking progesterone to breast cancer. This review tries to describe the physiological functions of progesterone and its receptors, genomic and non-genomic signaling, splice variants, and a different aspect of progesterone signaling. Furthermore, we seek to address or attempt to discuss the following pertinent questions on steroid hormone signaling; How does progesterone influence breast cancer progres sion? How does it change the molecular pathways in breast cancer with different receptor statuses, the specific role of each isoform, and how does the ER/and PR ratio affect progesterone signaling?

DNA methylation markers in esophageal cancer: an emerging tool for cancer surveillance and treatment

xlomafota13 shared this article with you from Inoreader DNA methylation markers in esophageal cancer: an emerging tool for cancer surveillance and treatment Via American Journal of Cancer Research Am J Cancer Res. 2021 Nov 15;11(11):5644-5658. eCollection 2021. ABSTRACT Esophageal carcinoma (EC) is one of the most pervasive cancers in the world, with upwards of 500,000 new diagnoses, annually. Despite its prominence, advancements in the detection and treatment of EC have been marginal over the past 30 years and the survival rate continues to stay below 20%. This is due to the uncommonly heterogeneous presentation of EC which presents unprecedented challenges in improving patient survival and quality of care. However, distinct epigenetic alterations to the DNA methylome may provide an avenue to drastically improve the detection and treatment of EC. Specifically, the creation of novel biomarker panels that consist of EC-specific methylation markers have shown promise as a potential alternative to the more invasive, contemporary diagnostic methods. Additionally, growing insight into the biological and clinical properties of EC-spec ific methylation patterns have opened a window of opportunity for enhanced treatment; of growing interest is the application of "DNMT inhibitors" - a class of drugs which inhibit excessive methylation and have been shown to re-sensitize chemoresistant tumors. Here we provide a comprehensive review of the current advancements in EC DNA methylation to underscore a potential approach to its detection and treatment.

Development of KAM score to predict metastasis and worse survival in breast cancer

xlomafota13 shared this article with you from Inoreader Development of KAM score to predict metastasis and worse survival in breast cancer Via American Journal of Cancer Research Am J Cancer Res. 2021 Nov 15;11(11):5388-5401. eCollection 2021. ABSTRACT Some may think that prediction of metastasis is meaningless since metastatic breast cancer is currently incurable. We argue that effective identification of developing metastasis will enable us to design and conduct clinical trials specifically targeting those patients at high risk. The current study sought to generate the KAM score by 4 genes (BRSK2, EYA1, SIGLEC15, and AGTR1) overexpressed in primary breast cancer that developed metastasis to bone compared with matched controls without metastasis longer than 10 years. A high KAM score was prognostic of poor overall (OS), disease free survival (DFS), and disease specific survival (DSS) in the METABRIC, and OS in the GSE96058 cohorts. A high KAM score was significantly associated with clinical aggressiveness, such as high American Joint Committee Cancer (AJCC) stage, lymph node metastasis, Nottingha m pathological grade, and triple negative breast cancer (TNBC). Subgroup analysis revealed that a high KAM score was associated with worse OS in ER-positive/HER2-negative breast cancer in both cohorts. A high KAM breast cancer enriched all 5 cell proliferation-related gene sets of the Hallmark collection and interferon (IFN)-γ response gene sets. Furthermore, a high KAM breast cancer was significantly infiltrated with a high fraction of not only anti-cancer but also pro-cancer immune cells and associated with high level of cytolytic activity. Finally, a high KAM breast cancer was significantly associated with lung metastasis. In conclusion, we developed KAM score using 4 gene expressions that predict lung metastasis and patient survival in breast cancer. PMID:34873467 | PMC:PMC8640803 View on the web Inoreader.
