[Participation indicators of organized mammography screening in Hungary between 2012-2021]. / A szervezett lakossági mammográfiás emloszurés részvételi mutatói 2012­2021 között Magyarországon.

The aim of our study is to analyze the participation indicators of screening rounds Nr. 6-10 (2012-2021) of the organized nationwide mammography screening program. Data derived from the nationwide financing database of the Hungarian National Health Insurance Fund Management and covered the period 2012-2021. We analyzed both diagnostic and screening mammography examinations. Between 2012 and 2019 the coverage (screening and diagnostic mammography) varied between 48.1-51.5, which decreased to 31.8% in 2020-2021. Within total coverage, the organized screening rate declined from 30.3-31.2 to 20.0, while the diagnostic mammography rate decreased from 17.7-20.7% to 11.8%. We can conclude that the number of both the diagnostic and screening mammography declined. In order to reduce the mortality of breast cancer, participation rate of mammography screening program should be increased.

Hemizygous nonsense variant in the moesin gene (MSN) leads to a new autoimmune phenotype of Immunodeficiency 50.

Here, we present the findings of an investigation involving two male siblings with juvenile total tooth loss, early-onset chronic leg ulcers, and autoimmune thyroiditis, as well as focal segmental glomerulosclerosis with associated pulmonary emphysema in one and diabetes mellitus in the other. The clinical picture and lupus anticoagulant, cryoglobulin, and cold agglutinin positivity suggested the diagnosis of antiphospholipid syndrome. Flow cytometry analysis showed immunophenotypes consistent with immune dysregulation: a low number of naive T cells, elevated CD4+ T cell counts, and decreased CD8+ T-cell counts were detected, and more than half of the T-helper population was activated. Considering the siblings' almost identical clinical phenotype, the genetic alteration was suspected in the background of the immunodeficiency. Whole exome sequencing identified a previously not described hemizygous nonsense variant (c.650G>A, p.W217X) within exon 6 of the moesin (MSN) gene localized on chromosome X, resulting in significantly decreased MSN mRNA expression compared to healthy controls. We present a putative new autoimmune phenotype of Immunodeficiency 50 (MIM300988) characterized by antiphospholipid syndrome, Hashimoto's thyroiditis, leg ulcers, and juvenile tooth loss, associated with W217X mutation of the MSN gene.

False-Positive Malignant Diagnosis of Nodule Mimicking Lesions by Computer-Aided Thyroid Nodule Analysis in Clinical Ultrasonography Practice.

This study aims to test computer-aided diagnosis (CAD) for thyroid nodules in clinical ultrasonography (US) practice with a focus towards identifying thyroid entities associated with CAD system misdiagnoses. Two-hundred patients referred to thyroid US were prospectively enrolled. An experienced radiologist evaluated the thyroid nodules and saved axial images for further offline blinded analysis using a commercially available CAD system. To represent clinical practice, not only true nodules, but mimicking lesions were also included. Fine needle aspiration biopsy (FNAB) was performed according to present guidelines. US features and thyroid entities significantly associated with CAD system misdiagnosis were identified along with the diagnostic accuracy of the radiologist and the CAD system. Diagnostic specificity regarding the radiologist was significantly (p < 0.05) higher than when compared with the CAD system (88.1% vs. 40.5%) while no significant difference was found in the sensitivity (88.6% vs. 80%). Focal inhomogeneities and true nodules in thyroiditis, nodules with coarse calcification and inspissated colloid cystic nodules were significantly (p < 0.05) associated with CAD system misdiagnosis as false-positives. The commercially available CAD system is promising when used to exclude thyroid malignancies, however, it currently may not be able to reduce unnecessary FNABs, mainly due to the false-positive diagnoses of nodule mimicking lesions.

[Subtotal petrosectomy - indications, surgical technique, experiences in Pécs]. / Subtotalis petrosectomia ­ javallatok, mutéti technika, pécsi tapasztalatok.

Introduction: Subtotal petrosectomy (STP) has been known for decades and it is considered being on the borderline between ear and skull-base surgery. Due to its excessive radicalism and adverse effects on hearing, it has been a forgotten surgical technique until recently. Over the last decade, due to its many benefits and the ability to combine it with modern hearing rehabilitation methods, STP has reappeared, providing a definitive solution to a number of problematic middl-ear disorders. Aim: In our retrospective clinical study, we wanted to highlight the effectiveness of STP, analyzing the efficiency of this surgery for the first time in domestic patient records, and to report our own experiences to date. Method: We processed data from 45 surgeries on our 44 patients. In addition to presenting the various surgical indications, we review the steps of the operation, analyze the audiological results, including the various methods of hearing rehabilitation, and also analyze the complications that have occurred. Our results are also summarized in the light of international professional literature. Results: Of our 44 patients, 23 were female and 21 were male. Patients had a mean age of 44.6 ± 20.5 years and a mean follow-up of 23 ± 16 months. Of our patients, 25 (57%) had undergone at least two previous unsuccessful ear operations, and 6 (14%) had deafness before surgery. The most common indication was chronic otitis media with cholesteatoma. 13 patients underwent 14 cochlear implantations (23%), in addition 6 patients received bone anchored hearing aids (BAHA) (14%), and 2 patients (5%) underwent VSB (Vibrant Soundbridge) placement against the round window membrane. Complications occurred in 11 of our patients, the most common of which was cerebrospinal fluid leak (5 cases, 11%) and wound dehiscence (3 cases, 7%). Data from 3 patients were available for processing the audiological results. Conclusion: STP is an extremely favorable surgical solution for a number of middle-ear pathologies that have previously caused major problems. The main reason for its growing popularity is that it can be combined with a number of modern, effective methods of hearing rehabilitation. Orv Hetil. 2020; 161(14): 544-553.

Visualization of mucosal field in HPV positive and negative oropharyngeal squamous cell carcinomas: combined genomic and radiology based 3D model.

The aim of this study was to visualize the tumor propagation and surrounding mucosal field in radiography-based 3D model for advanced stage HNSCC and combine it with HPV genotyping and miRNA expression characterization of the visualized area. 25 patients with T1-3 clinical stage HNSCC were enrolled in mapping biopsy sampling. Biopsy samples were evaluated for HPV positivity and miR-21-5p, miR-143, miR-155, miR-221-5p expression in Digital Droplet PCR system. Significant miRNA expression differences of HPV positive tumor tissue biopsies were found for miR-21-5p, miR-143 and miR-221-5p compared to the HPV negative tumor biopsy series. Peritumoral mucosa showed patchy pattern alterations of miR-21-5p and miR-155 in HPV positive cases, while gradual change of miR-21-5p and miR-221-5p was seen in HPV negative tumors. In our study we found differences of the miRNA expression patterns among the HPV positive and negative tumorous tissues as well as the surrounding mucosal fields. The CT based 3D models of the cancer field and surrounding mucosal surface can be utilized to improve proper preoperative planning. Complex evaluation of HNSCC tissue organization field can elucidate the clinical and molecular differentiation of HPV positive and negative cases, and enhance effective organ saving therapeutic strategies.

[First report on successful application of nivolumab in Hungary for the treatment of locally recurrent head and neck squamous cell carcinoma]. / Immunterápia elsõ hatékony alkalmazása Magyarországon lokálisan kiújult fej-nyaki laphámkarcinómás betegnél.

The prognosis for recurrent/metastatic head and neck squamous cell cancer (R/M HNSCC) remains dismal and its treatment poses a challenge for oncologists. Nivolumab belongs to the class of immune checkpoint inhibitors (ICI) and is an antibody developed to target the programmed cell death protein 1 (PD-1) receptor. The CheckMate 141 randomized phase 3 trial proved the efficacy of nivolumab in the treatment of R/M HNSCC as it was shown to significantly increase overall survival and quality of life. We present the case of a 53-year-old woman with R/M HNSCC who was given nivolumab monotherapy, as third-line treatment due the progression of her tumor. After treatment with nivolumab, the size of her tumor decreased, then was stable, while she did not experience any adverse events or notable side effects. Our case report is the first to demonstrate the application of nivolumab in R/M HNSCC in Hungary.
