Angiomyofibroblastoma férfiban – egy ritka paratesticularis eltérés és irodalmi áttekintés

Összefoglaló. A scrotum képalkotó vizsgálóeljárásai közül elsőnek választandó az ultrahang, mivel könnyen hozzáférhető, szenzitivitása és specificitása magas. Szerepe kiemelendő mind az intratesticularis eltérések differenciáldiagnózisában, mind pedig a kevésbé ismert paratesticularis eltérések esetében. Az urológiai ambulancián egy 56 éves férfi jelentkezett kivizsgálásra tapintható terime miatt. Ultrahangvizsgálattal paratesticularis elváltozás látszódott, mely a vizsgálat során az inguinalis csatorna irányába többször elmozdult. A laesio dignitása nem volt meghatározható, ezért műtéti eltávolításra került sor. A szövettani vizsgálat a férfiak körében ritkán előforduló angiomyofibroblastoma diagnózisát véleményezte. A paratesticularis elváltozások ugyan ritkán fordulnak elő, de a gyakoribb entitások és azok ultrahangos sajátosságainak ismerete elengedhetetlen a terápia tervezése szempontjából. Orv Hetil. 2021; 162(34): 1376–1382. Summary. Ultrasonography is the basic imaging technique for the evaluation of testicular structures because it is easily accessible and has high sensitivity and specificity. It plays a significant role in the differential diagnosis of intratesticular changes, in addition, its role should be emphasised in rare paratesticular abnormalities. A 56-year-old male presented in the urology department complaining of a palpable inguinal mass and was referred to ultrasonography for further evaluation. A scrotal ultrasound was performed, and it described a mobile paratesticular mass without any specific characterizations. Therefore the lesion was removed, and the histological analysis established the diagnosis of angiomyofibroblastoma. Paratesticular lesions are rare, but it is essential to know the frequent abnormalities and the corresponding ultrasound findings for planning of treatment. Orv Hetil. 2021; 162(34): 1376–1382.

Background:Tuberculosis (TB), one of the leading causes of death worldwide, is difficult to diagnose based only on signs and symptoms. Methods for TB detection are continuously being researched to design novel effective clinical tools for the diagnosis of TB.Objective:This article reviews the methods to diagnose TB at the latent and active stages and to recognize prospective TB diagnostic methods based on nanomaterials.Methods:The current methods for TB diagnosis were reviewed by evaluating their advantages and disadvantages. Furthermore, the trends in TB detection using nanomaterials were discussed regarding their performance capacity for clinical diagnostic applications.Results:Current methods such as microscopy, culture, and tuberculin skin test are still being employed to diagnose TB, however, a highly sensitive point of care tool without false results is still needed. The utilization of nanomaterials to detect the specific TB biomarkers with high sensitivity and specificity can provide a possible strategy to rapidly diagnose TB. Although it is challenging for nanodiagnostic platforms to be assessed in clinical trials, active TB diagnosis using nanomaterials is highly expected to achieve clinical significance for regular application. In addition, aspects and future directions in developing the high-efficiency tools to diagnose active TB using advanced nanomaterials are expounded.Conclusion:This review suggests that nanomaterials have high potential as rapid, costeffective tools to enhance the diagnostic sensitivity and specificity for the accurate diagnosis, treatment, and prevention of TB. Hence, portable nanobiosensors can be alternative effective tests to be exploited globally after clinical trial execution.

Aim and Objective: To estimate the relationship between Coronary Calcium Scoring (CCS)and presence of different degrees of obstructive coronary artery disease (CAD) to avoid unnecessary examinations and hence unnecessary radiation exposure and contrast injection. Background: Coronary Calcium Scoring (CCS) is a test uses x-ray equipment to produce pictures of the coronary arteries to determine the degree of its narrowing by the build-up of calcified plaques. Despite the lack of definitive data linking ionizing radiation with cancer, the American Heart Association supports widely that practitioners of Computed tomography Coronary Angiography (CTCA) should keep “patient radiation doses as low as reasonably achievable but consistent with obtaining the desired medical information”. Methods: Data obtained from 275 CTCA examinations were reviewed. Radiation effective doses were estimated for both CCS and CTCA, measures to keep it as low as possible were presented, CCS and Framingham risk estimate were compared to the final results of CTCA to detect sensitivity and specificity of each one in detecting obstructive lesions. Results: CCS is a strong discriminator for obstructive CAD and can with high sensitivity and specificity and correlates well with the degree of obstruction even more than Framingham risk estimate which has high sensitivity and low specificity. Conclusion: CCS helps reducing the effective radiation dose if properly evaluated to skip unnecessary CTCA if obstructive lesions was unlikely, and as a test does not use contrast material, harmful effect on the kidney will be avoided as most of coronary atherosclerotic patients have renal problems.

Cancer tissues have characteristic DNA methylation profiles compared with their corresponding normal tissues that can be utilized for cancer diagnosis with liquid biopsy. Using a genome-scale DNA methylation approach, we sought to identify a panel of DNA methylation markers specific for cell-free DNA (cfDNA) from patients with colorectal cancer (CRC). By comparing DNA methylomes between CRC and normal mucosal tissues or blood leukocytes, we identified eight cancer-specific methylated loci (ADGRB1, ANKRD13, FAM123A, GLI3, PCDHG, PPP1R16B, SLIT3, and TMEM90B) and developed a five-marker panel (FAM123A, GLI3, PPP1R16B, SLIT3, and TMEM90B) that detected CRC in liquid biopsies with a high sensitivity and specificity with a droplet digital MethyLight assay. In a set of cfDNA samples from CRC patients (n = 117) and healthy volunteers (n = 60), a panel of five markers on the platform of the droplet digital MethyLight assay detected stages I–III and stage IV CRCs with sensitivities of 45.9% and 95.7%, respectively, and a specificity of 95.0%. The number of detected markers was correlated with the cancer stage, perineural invasion, lymphatic emboli, and venous invasion. Our five-marker panel with the droplet digital MethyLight assay showed a high sensitivity and specificity for the detection of CRC with cfDNA samples from patients with metastatic CRC.
