Objective:a comparative “blind” assessment of the thyroid nodules identified by ultrasound, according to the TI-RADS scale in various modifications.Materials and methods.Retrospective analysis of 149 echograms  of thyroid nodules by three independent experts was performed (the  experience of ultrasound of thyroid ultrasound for more than 7 years).Results. In solid nodules, high-specific large (more than 94%) and  small (more than 90%) ultrasound signs of thyroid cancer have been identified. The nodes are stratified according to the TI-RADS system: 1 – in the modification J.Y. Kwak et al. (2011), 2 – according to the  proposed system, taking into account small ultrasound signs of  thyroid cancer. High reproducibility of both systems are obtained. In the first system 13.7% of cancer nodes fell into the category of TI- RADS 3 (benign formations), in the second system only 5% of  cancers fell into the category of TI-RADS 3, which is important for  biopsy selection. The sensitivity of the first system was TI-RADS  82.05%, of the second system – 94.87%.Conclusions.Classification of TI-RADS can be used to interpret the  ultrasound results of thyroid nodules, taking into account both the  main large and small ultrasound signs of cancer. For its validation in  our country, it is necessary to further broad discussion of the proposed TI-RADS system.

Objectives The aim of this study was to determine whether preoperative ultrasound imaging characteristic(s) in cats suffering from unilateral benign ureteral obstructions are predictive of outcome after successful renal decompression with a subcutaneous ureteral bypass (SUB) device. Methods This was a retrospective study of 37 cats with unilateral, benign ureteral obstruction. Preoperative imaging characteristics (including renal pelvis diameter, parenchymal thickness [transverse plane], renal length and pelvic size:overall renal size) and biochemical data were evaluated for all cats diagnosed with a unilateral ureteral obstruction treated with a SUB device. Any patient with bilateral obstructions or documented bacteriuria/infection in the data collection period was excluded. All patients were followed between 3 and 6 months postoperatively to obtain postoperative biochemical data. Long-term outcome was defined as serum creatinine concentration at 3–6 months postoperatively. Results No preoperative imaging characteristics or biochemical findings were found to be significantly associated with long-term serum creatinine concentrations. The length of the kidney was found to be associated with change in blood urea nitrogen and creatinine with decompression but not with long-term renal values. Conclusions and relevance In this study, long-term renal function based on preoperative ultrasound imaging findings could not be predicted in cats with unilateral ureteral obstruction, regardless of the severity of the biochemical parameters, renal pelvic dilation (large or small pelvis), kidney size or thickness of renal parenchyma assessed.

Primary diagnostics of thyroid neoplasms remains actual issue of modern endocrinology. Comprehensive clinical examination, ultrasound, and fine needle biopsy enable to make a conclusion about thyroid nodule properties but with a lot of mistakes, and take much time. Aims: assessment of diagnostic value of ultrasound criteria those may direct at papillary thyroid cancer. Materials and methods: one carried out observation multicenter retrospective continuous research among patients undergone for thyroid nodules surgery. It included adult patients (18-78) of both sexes. Patients’ case reports within 2013-2019 were sampled. Patients were shared into 2 groups according to final histological results. Results: the objects of research were 124 in-patients’ case reports. 32 of them were diagnosed thyroid cancer (24 - papillary, 8 – follicular), and 92 – benign nodules. Among searched criteria all (except hypoechogenicity) evidently differed between benign nodules and papillary cancer. In comparison criterion «absence of thin halo» reached the upper border of evidence of suspicion for papillary cancer. Multiple comparison indicated statistical difference between benign nodules (p<0,001) and follicular cancer (p<0,05). 2 of 24 papillary cancer patients (9%) in ultrasound did not demonstrate any criterion; all after this were arranged to benign nodules. 21 of 24 patients (88%) with 2 and more positive criteria were assessed correctly, but 51 of 92 benign nodules (56%) in ultrasound were assessed as papillary cancer. Conclusions: ultrasound imaging accuracy in thyroid papillary cancer is approximately equal in presence of 2 to 4 criteria; maximum accuracy (74%) is reached in presence of 3 criteria. In presence of 1 or 5 criteria is significantly lower: in 1 criterion due to low specificity, in 5 criteria – due to rarity of simultaneous combination. Follicular cancer can’t be identified in ultrasound imaging.

Cancer In Children

Overdiagnosis is the detection of a disease that does not do any harm to the patient throughout the lifetime. Thyroid cancer in children is a rare disease; however, since 2011, many children in Fukushima, Japan, have been diagnosed with it, and the number has shown a steady increase to over 200 cases at present. Some experts have stated that this phenomenon is due to overdiagnosis caused by thyroid ultrasound (US)-based thyroid screening detecting self-limiting thyroid cancer, which will not lead to clinical symptoms in the future. Harm caused by overdiagnosis of thyroid cancer is more serious in the young, since it is difficult to perform active surveillance and children diagnosed with cancer are likely to suffer from stigma. Thus, overdiagnosis of thyroid cancer in the young is not only a health problem but also a problem of human rights. Conflicts of interest among people related to screening programs and some experts with incomplete knowledge on overdiagnosis help to spread misleading opinions together with fear of radiation exposure among residents, which has led to their erroneous understanding of the nature of US-based thyroid screening. Scientific and honest discussions among experts to enhance education of residents and consideration of medical ethics are crucial to prevent the expansion of overdiagnosis.

Acute Pelvic Inflammatory Disease

Common types of gynecological acute abdomen include ovarian cyst pedicle torsion, ectopic pregnancy, luteal rupture, and acute pelvic inflammatory disease. Make accurate diagnosis and surgical treatment of acute abdomen patients in obstetrics and gynecology in time, otherwise it will cause life danger or loss of organ function, therefore, accurate and timely diagnosis and treatment of gynecological acute abdomen is very important for the prognosis of patients. Ultrasound imaging has important clinical value for the diagnosis of acute abdomen in obstetrics and gynecology. Ultrasound imaging has the advantages of simple examination, rapid reporting, and no pain in the subject, which is one of the best methods for diagnosing acute abdomen in obstetrics and gynecology. This study analysed and summarized the imaging principles of ultrasound imaging in acute obstetrics and gynecology and the imaging characteristics of various acute abdomen. A retrospective analysis of patients with acute obstetrics and gynaecology performed in our hospital from December 2017 to June 2019 was performed. The diagnostic analysis of ultrasound imaging in acute obstetrics and gynaecology was performed. The results showed that the ultrasound imaging diagnosis results of 202 obstetric and gynecological acute abdomen patients were compared with the results of surgery and pathological diagnosis. Among the 182 cases with correct ultrasound imaging diagnosis, the coincidence rate was 90.1%, and 20 cases were misdiagnosed, accounting for 9.9%. The research of this study shows that the ultrasound examination technique for patients with acute obstetrics and gynaecology is simple, fast, non-invasive, and has high accuracy. Ultrasound imaging can provide reliable objective evidence for the diagnosis and differential diagnosis of most acute abdominal diseases, in order to improve the diagnosis rate and reduce the misdiagnosis rate.

Neonatal Thyroid Screening

Abstract. When discovered by neonatal screening, a thyroid dyshormonogenesis is usually not recognized as a goitre. Especially a total iodide transport defect can easily be misclassified as thyroid agenesis, since radionuclide imaging cannot visualize the thyroid. We present the only iodide transport defect ever discovered in the Netherlands, the 35th reported in the literature, and the first one found exclusively as a result of neonatal screening. We demonstrate that iodide transport defects, in common with organification and deiodinase defects, can be distinguished from thyroid dysgenesis by demonstrating a normal or enlarged thyroid ultrasound image, and especially by measuring very high serum thyroglobulin levels (above 1000 pmol/l). In the presented case, an iodide-123 saliva-to-serum ratio near unity completed the etiologic classification. Measurement of serum thyroglobulin levels, in combination with thyroid ultrasound imaging, will improve the early identification of hereditary types of congenital hypothyroidism, and especially iodide transport defects, in patients found by neonatal thyroid screening.

Abstract Purpose To determine the ultrasound imaging characteristics of participants with bronchial anthracofibrosis (BAF) and identify clinical markers for prevention and treatment. Methods We randomly selected 1,243 participants (including 113 with BAF) who underwent bronchoscopy and treatment at our institution from April 2018 to October 2019. BAF was classified as flat, deep seated retracted, or mucosal protrusion type, based on microscopy. Ultrasound probes were used to determine the maximum thickness of the tube wall and submucosa. The average values of the submucosal and bony tissue areas of the BAF subtypes were compared. Results The BAF group included 13 participants with a history of tuberculosis (11.5%) and 57 with biofuel exposure (50.4%). The average exposure time was 17.4 ± 6.2 years; BAF accounted for 10% of bronchoscopies performed. The maximum tube-wall thicknesses of the deep-seated retracted (17.3 ± 5.7) and black protruding (19.3 ± 5.4) groups were significantly greater than that of the flat group (12.5 ± 5.0; P < 0.05). The maximum thicknesses of the submucosa in the deep-retracted (9.8 ± 3.0) and black protruding (14.5 ± 5.0) groups were significantly greater than that of the flat group (6.6 ± 3.5; P < 0.05). The ratios of bone tissue in the flat and black protruding groups were 33.3 ± 9.3% and 34.9 ± 12.1%, respectively; the ratio in the deep-seated retracted group (65.2 ± 8.7%) was significantly reduced (P < 0.05). The flat type showed no significant change (P > 0.05). Conclusion Differences in BAF airway remodeling among the different subtypes may lead to varying clinical symptoms. Analyzing the characteristics of BAF airway remodeling and the regulatory pathway may provide new clues for treatment.

Abstract Introduction: Prevalence of thyroid nodules in the adult population based on detection by ultrasonography is about 20-76% of which only 5% account for thyroid cancer. All patients with a suspected thyroid nodule either on physical examination or noted incidentally on other imaging should be evaluated with thyroid ultrasound. Any thyroid nodule &gt;= 1 cm on ultrasound should be investigated with FNAC. Ultrasound guided FNAC techniques are used to reduce false negative results. We present a patient with suspicious finding on initial thyroid ultrasound and subsequent negative FNAC presenting a few years later with papillary thyroid cancer. Case Presentation: A 32 y.o. female with history of thyroid nodule and thyroiditis presented to the endocrine clinic for follow-up of her thyroid nodule. 5 years ago, she was diagnosed with thyroid nodule, which was found on an ultrasound scan for workup of her dysphagia. The thyroid ultrasound then showed diffusely heterogeneous thyroid gland with an ill-defined area of decreased echogenicity in the right lobe and left superior lobe and possible nodule in the lower pole left thyroid. Blood work showed TSH of 1.71 (n 0.34-3.00 uIU/ml) and thyroid peroxidase antibody levels was 27.8 (n &lt; 9.0 IU/ml). A CT scan of neck with contrast was done and no concerning mass was seen. The patient had a follow-up ultrasound after 8 months which showed small bilateral thyroid lesions, somewhat ill-defined. The patient had an FNA biopsy of the right thyroid nodule: the results were consistent with a benign follicular nodule. A follow-up thyroid ultrasound was done in a year, and the findings were unchanged. The patient came back 3 years later for follow-up with complaints of a new palpable nodule in the neck. Ultrasound showed unchanged right thyroid nodule and some new cervical adenopathy. The ultrasound showed a 2.2 cm heterogeneous lymph node with punctate echogenic foci along the right lateral margin of the right internal jugular vein at the level of the thyroid gland, Subsequently FNA biopsy of the right cervical node and right thyroid node were done. The cells from lymph nodes were positive for malignancy and cells from the right thyroid nodule were atypical. Overall the appearance was consistent with papillary thyroid carcinoma. Subsequently the patient underwent total thyroidectomy and right modified lymph node dissection and the pathology results came back as multifocal papillary thyroid cancer right side 1.2 cm and left side 0.4 cm, with metastasis to 2 lymph nodes. Conclusion: The reported false negative rate of ultrasound-guided FNAC is variable. Success of US-FNA depends on experience of operator and cyto-pathologist and the intrinsic nature of the nodule. Malignancy rates of only 1-2% are reported with repeat FNA in prior benign nodules. Good FNA techniques and real-time visualization of needle in target nodules can further decrease false negatives.
