Abstract
PURPOSE In order to spread competence in vaginal breech deliveries, it is necessary to develop new and easily applicable tools for birth progression and safety evaluation. Ultrasound is a useful and ubiquitously available tool with already documented value for birth progression observation. In deliveries out of breech presentation, an established ultrasound examination is missing. We determined the descent of the fetal buttocks in relation to the maternal pelvic inlet using intrapartum ultrasound. We evaluated these results in comparison to the clinical vaginal examination with the aim to establish an easily applicable method for birth outcome prediction. Therefore, we analyzed the predictive value of our examinations on birth outcome parameters, such as cesarean section rate, as well as fetal and maternal outcome parameters. METHODS We performed a prospective blinded study on 106 mothers with vaginally intended breech delivery. At beginning of stage two in labor, the descent of the fetal buttocks into the mother's pelvic inlet was detected with transabdominal ultrasound and vaginal examination by different observers. PRIMARY OUTCOME VARIABLE Cesarean section rate. Secondary outcome variables: rate of manual assistance in vaginal deliveries, birth duration, 5' APGAR score, umbilical arterial pH, maternal blood loss, and perineal injury. For non-parametric values, Wilcoxon's χ2 test was performed. In order to analyze the predictive value of our examination, lack-of-fit analysis was conducted. Reliability evaluation of the sonographic examination was done with a matched-pair analysis. RESULTS Women with positive intrapartum ultrasound breech engagement sign (+ IPUBES) had a significantly lower rate of cesarean section in comparison with those with negative IPUBES (5/67; 7.5% vs. 18/39; 46.2%; p < 0.0001). The area under the ROC curve for the prediction of CS for negative IPUBES was 0.765 with a sensitivity of 78.3% and a specificity of 74.7%. Sonographic examination showed an excellent reliability in a matched-pair analysis comparing vaginal and sonographic examinations with a mean difference of 0.012 (SD ± 0.027, 95% CI - 0.014 to 0.065). Mean birth duration was significantly longer in deliveries with negative IPUBES (533 min vs. 440 min; p = 0.0011). Fetal and maternal outcome parameters were not significantly different between deliveries with positive and negative IPUBES. CONCLUSIONS Sonographic evaluation of the fetal descent in relation to the mother's pelvic inlet screens reliably for emergency cesarean section. This newly presented method for birth progression observation might be a powerful tool for distribution of expertise in vaginal breech delivery and is able to give reference for clinical vaginal examination by obstetricians in training.

Abstract
A retrospective study was carried out to investigate incidence, clinical signs and ultrasonographic findings of ovarian tumours in a population of dogs referred to the Veterinary Teaching Hospital of the University of Perugia (Italy) and Anicura Tyrus Veterinary Clinic (Terni, Italy). The period of study ranged from January 2005 to December 2021. A total of 1910 dogs were affected by neoplasia but only 35 of them (1.8%), of different breeds and ages, were found to have ovarian tumours. Ultrasound of the ovaries was performed based on clinical signs; the diagnosis was achieved after ultrasound findings prompted ovariohysterectomy and ovarian pathologic evaluation In our study, the age of bitches affected by ovarian neoplasia ranged from 3 to 20 years (mean 9.6 ± 3.8). The histopathological findings of ovarian masses identified 16 granulosa cell tumours (GCT) (46%), 7 adenomas (20%), 5 adenocarcinomas (14%), 2 teratomas (6%), 1 leiomyoma (3%), 1 luteoma (3%), 1 tecoma (3%), 1 dysgerminoma (3%), and 1 haemangiosarcoma (3%). In particular, with respect to clinical signs, 69% of bitches showed abnormalities of estrus cycle (short interestral interval, persistent estrus, prolonged interestral interval). The other main clinical signs included abdominal distention, palpable abdominal mass, vulvovaginal discharge, polyuria/polydipsia, mammary masses. When present, the laboratory abnormalities were slight anemia and leucocytosis with neutrophilia. The tumours were ultrasonographically classified as mainly solid: 12/35 (34%) (1 adenoma, 4 adenocarcinomas, 1 dysgerminoma, 1 haemangiosarcoma, 1 leyomioma, 1 luteoma, 1 GCT, 1 tecoma, 1 teratoma); solid with cystic component 13/35 (37%) (9 GCT, 2 Adenomas, 1 adenocarcinoma, 1 teratoma); and mainly cystic 10/35 (29%) (6 GCTs, 4 adenomas). In our study, the ultrasound examination allowed us to suspect ovarian neoplasia in asymptomatic subjects referred for breeding management or for preventive health check. On the basis of our data, we proposed to perform a complete periodic examination of the reproductive system once a year from 6 years. Nevertheless, the presence of ovarian neoplasms found in young subjects, during breeding management, suggest including routine ultrasound examination of the reproductive tract.

Abstract
RATIONALE AND OBJECTIVES This study aimed to investigate the reliability and accuracy of high-resolution ultrasonography (US) for diagnosing periapical lesions and differentiating radicular cysts from granulomas. MATERIALS AND METHODS This study included 109 teeth with periapical lesions of endodontic origin from 109 patients scheduled for apical microsurgery. Ultrasonic outcomes were analyzed and categorized after thorough clinical and radiographic examinations using US. B-mode US images reflected the echotexture, echogenicity, and lesion margin, while color Doppler US assessed the presence and features of blood flow of interested areas. Pathological tissue samples were obtained during apical microsurgery and subjected to histopathological examination. Fleiss' κ was used to measure interobserver reliability. Statistical analyses were performed to assess the diagnostic validity and the overall agreement between US and histological findings. The reliability of US compared to histopathological examinations was assessed based on Cohen's κ. RESULTS The percent accuracy of US for diagnosing cysts, granulomas, and cysts with infection based on histopathological findings was 89.9%, 89.0%, and 97.2%, respectively. The sensitivity of US diagnoses was 95.1% for cysts, 84.1% for granulomas, and 80.0% for cysts with infection. The specificity of US diagnoses was 86.8% for cysts, 95.7% for granulomas, and 98.1% for cysts with infection. The reliability for US compared to histopathological examinations was good (κ = 0.779). CONCLUSION The echotexture characteristics of lesions in US images correlated with their histopathological features. US can provide accurate information on the nature of periapical lesions based on the echotexture of their contents and the presence of vascularity. It can help improve clinical diagnosis and avoid overtreatment of patients with apical periodontitis.

Abstract
INTRODUCTION The injuries of the external genital organs in men accounts for 30-50% of the total number of injuries of genitourinary system. In half of the cases, there is a trauma of the penis. In 80% of cases, trauma of the penile or scrotal area occurs. AIM To study the role of Doppler ultrasound in diagnosing injuries of the scrotum and penis. MATERIALS AND METHODS The analysis of Doppler ultrasound study of the scrotum and penis in 32 patients with injuries of the external genital organs was carried out. RESULTS The analysis revealed various ultrasonographic variants of damage to the penis and scrotum. In the vast majority of cases, scrotal trauma without testicular rupture (n=15; 46%) and with testicular rupture (n=11; 33%) was seen. Penile injury was diagnosed in 6 (19%) patients. CONCLUSION Doppler ultrasound is a gold standard for diagnosing injuries of the scrotum and penis. The mandatory ultrasound study allows to determine the indications and type of salvage surgical procedure.

Abstract
BACKGROUND Lipohypertrophy (LHT) has been suggested as an outcome of the adipogenic effects of insulin injection-related tissue trauma. It commonly occurs in the clinical setting, but the current understanding of LHT by the medical staff and diabetes patients remains insufficient; moreover, it has not garnered attention as a research topic. OBJECTIVE To investigate the ultrasound characterization of LHT, to identify the factors associated with LHT development by assessing the prevalence of LHT and compare the accuracy of clinical palpation with that of ultrasonography in LHT detection, and to further evaluate the possible impact of LHT on patients' blood glucose fluctuations. METHOD A cross-sectional study was conducted in 120 patients with type 2 diabetes. Patients' general information were obtained using a questionnaire, and the patients were evaluated for LHT by ultrasonography and clinical palpation of the abdomen. The patients were instructed to inject equal amounts of insulin in tissues with LHT and in normal adipose tissues (NATs) in two non-consecutive d in a selected week; the possible effect of LHT on patients' blood glucose fluctuations was assessed using a continuous glucose monitoring system. RESULTS LHT has characteristic ultrasonic signs. We found a high rate of missed LHT detection on clinical palpation compared with that on ultrasonography (P < 0.05). The duration of insulin treatment, rotation of injection sites, frequency of needle reuse, and number of insulin injections per day were the primary factors influencing the development of LHT (P < 0.05). Compared with NATs, LHT tissues showed extremely elevated amplitude of glycemic excursion, mean blood glucose levels, standard deviation of blood glucose levels and postprandial glucose excursion, and large fluctuations in blood glucose levels (P < 0.05). CONCLUSION Ultrasonography can more accurately detect LHT than can clinical palpation. LHT development is associated with several factors and can lead to significant fluctuations in blood glucose levels; thus, sufficient attention should be paid to investigating the underlying mechanism of LHT.

Abstract
Objectives: In order to understand the incidence and epidemiological characteristics of gestational diabetes mellitus, the ultrasound imaging of support vector machine processing algorithm was used to clarify the outcome of maternal and neonatal gestational diabetes mellitus. Methods: This study selected clinical data of 12,190 pregnant women who were hospitalized for delivery, and were divided into diabetic group (1268 cases) and control group (10922 cases) according to the diagnosis of gestational diabetes. The study was conducted from January 1, 2012 to December 31, 2019. Colour Doppler ultrasound was performed to record fatal umbilical artery and brain the middle arteries and uterine arteries which are effective indicators of measuring fatal intrauterine conditions. Chi-square test was used to compare the rates between groups, and multivariate logistic regression was used for labour outcomes. Results: The incidence of diabetes during pregnancy is about 10.4% (1268/12190). Senior citizens and women suffering from obesity increase the risk of gestational diabetes, maternal hypertension disorders in pregnancy, premature rupture of membranes, oligohydramnios, fatal distress, multiple births, malpresentation risk increased significantly (P <0.05) than the control group. In gestational diabetes caesarean section rate was significantly higher (61.0% vs46.4%). Caesarean new born 5-minute Apgar score was significantly lower than the control group (P <0.05). Conclusion: In maternal gestational diabetes in high risk pregnancies, complications of pregnancy significantly increase the importance of enhancing weight management and blood glucose monitoring to reduce complications.

Abstract
OBJECTIVES This study evaluates the cost-effectiveness of ultrasound (US) only; computed tomography (CT) only; and combined US-CT in a base-case that underwent total thyroidectomy for a newly diagnosed papillary thyroid carcinoma (PTC) (scenario I) or surgery for recurrent disease (scenario II). MATERIALS AND METHODS Markov chain model was developed comparing the above modalities. Follow-up time was set as 10 years. Costs and probabilities values are obtained from literature and the National Cancer Database. RESULTS Nodal mapping of the central compartment in both primary and recurrent PTC scenarios demonstrated combined utilization of preoperative US and CT is preferred over the use of US or CT separately; the final incurred management cost was [scenario I: U.S.$10,548.25 - scenario II: U.S.$11.197.88] and effectiveness was [scenario I: 6.875 Quality-adjusted-life-year (QALY) - scenario II: 6.871 QALY]. Nodal mapping of the lateral compartments favored US alone as the cost-effective modality in both scenarios; the final incurred management cost was [scenario I: U.S.$10,716.60 - scenario II: U.S.$11,247.92] and effectiveness was [scenario I: 6.879 QALY - scenario II: 6.883 QALY]. Sensitivity analysis demonstrated that for combined utilization of US and CT scans to remain cost-effective, the cost of a CT scan should be less than U.S.$1,127.54. CONCLUSIONS Based on the model, combined utilization of US and CT is cost-effective in nodal mapping patients with PTC.

Abstract
INTRODUCTION AND OBJECTIVE In the case of non-palpable testes, we often find a small nodule which is called "testicular nubbin (TN)" in scrotum or inguinal canal. There is no agreement about the treatment for TN. This time we investigated whether or not ultrasound examination (US) can be a useful modality for detecting TN. MATERIALS AND METHODS We recruited 66 boys who were diagnosed with non-palpable testes and who had undergone US studies. We examined age, affected side, size of the unaffected side, presence of testicular hypertrophy, and findings from US studies. Radiologists or sonographers familiar with examination of testicular nubbin carried out the ultrasound studies. When TN is detected in a patient, preservation or excision of the TN was chosen by their families. RESULTS Sixty-six boys and 76 testes were examined. Thirty-four testes (44.7%) were diagnosed as having TN, 39 (51.3%) were undescended testes, and 3 (3.9%) were retractile testes. The median age of all participants was 13 months (range: 2-118 months). The mean ages of patients with TN, undescended testes, and retractile testes were 7.6 months, 14.5 months and 55 months, respectively. The size ratio between the affected and unaffected sides in cases of TN was 0.144 (range; 0.03-0.48) and in cases of undescended testes was 0.99 (0.46-1.2). Thirty cases of TN (88.2%) had testicular hypertrophy on the unaffected side. Only one case of TN underwent excision; viable cells were not seen. A high US region was observed in 31 (91.1%) cases with TN. CONCLUSION US was a useful modality for detecting TN. From this study, TN can be detected if the size ratio between the affected and unaffected sides is < 0.4 and a high US region is seen. If TN can be detected using US, preservation can recommended, preventing unnecessary surgeries. However, there is no evidence on the required duration and interval of follow-up for these cases and examination will be needed over a period of time.

Abstract
OBJECTIVE To assess the potential of ultrasound examination (USE) as an adjunctive method to conventional radiology to evaluate the healing processes occurring after the treatment of bone lesions of the jaws. The research question was: what is the effectiveness of USE to evaluate the healing of intra-osseous bone lesions when compared to radiological or clinical examination? MATERIALS AND METHODS Six databases (PubMed, the Web of Science, Scopus, Embase, the Cochrane Library, and Best Evidence) were searched from their inception (PROSPERO CRD42019134482). A quality assessment was performed combining the Downs and Black tool and the Newcastle-Ottawa scale. The risk of bias was calculated using the Cochrane collaboration tool to assess the risk of bias. RESULTS A total of 4404 records were screened, and 7 studies meeting the inclusion criteria were included in the systematic review. USE allowed to evaluate the healing of jaw bone lesions by assessing their reduction in size, the increase in echogenicity of the affected area, and the progressive decrease\disappearance of the vascular flow signal within the lesions. CONCLUSIONS USE implemented with color power Doppler is an advanced imaging technique feasible to monitor the early and long-term response of the intra-osseous lesions of the jaws to both surgical and nonsurgical treatment. CLINICAL RELEVANCE This systematic review brought evidence that USE can constitute a safe alternative imaging technique in the dental clinical practice for the management of central lesions of the maxillary bones.

Abstract
OBJECTIVE To assess the value of multiple serum biomarkers for the prediction of successful outcome of expectant management in women with tubal ectopic pregnancy (TEP). STUDY DESIGN Women with a conclusive ultrasound diagnosis of TEP had a blood test to measure β-human chorionic gonadotropin (β-hCG), progesterone, inhibin A, activin A and high sensitivity C-reactive protein (hsCRP) at the initial visit. Women presenting with pain, serum β-hCG ≥ 1500 IU, evidence of a live ectopic pregnancy or a significant haemoperitoneum were advised to have emergency surgery. Women eligible for expectant management were followed-up prospectively until serum β-hCG declined to non-pregnant level or surgical treatment was required. RESULTS A total of 93 women with a TEP were included in the final cohort. Emergency surgery was carried out in 42/93 (45 %) of women whilst 51/93 (55 %) were managed expectantly. Of the latter group, 42/51 (82 %) had successful expectant management and 9/51(18 %) required surgical procedure after a period of follow up. On multi-variable analysis, only higher values of serum β-hCG and progesterone at the initial visit were associated with a lower chance of successful expectant management of TEP. A one-unit increase in either variable on the log-scale was associated with an approximate 20-fold reduction in the odds of a successful outcome. CONCLUSION(S) Serum β-hCG and progesterone were significantly lower in women who had successful expectant management of TEP. Other biomarkers under consideration were not significantly different in women with successful and failed expectant management.

Abstract
Purpose Shoulder pain and weakness are common symptoms in athletes who play sports connected with overhead throwing. Suprascapular neuropathy may be one of the reason of such signs.The aim of the study was to find out if ultrasound examination of the shoulder in athletes reveals signs of suprascapular neuropathy. Methods This was a cross-sectional study in which 67 professional volleyball, handball and rugby players of polish teams without shoulder disorders, which have played sport for 10 or more years, were included. An ultrasound examination of both shoulders was performed. Excluding criteria were recent shoulder and/or neck trauma and neurological disorders. Results No ultrasound signs of suprascapular neuropathy were seen in any player. The only finding was enthesopathy of supraspinatus muscle and this finding was connected with athletes' age, type of sport and with dominant hand. It had statistical significance with p-value respectively 0.01 for athletes' age, 0.0208 for sport type and 0.03 for dominant hand. Conclusions Ultrasonography should not be used as the screening examination of shoulders in athletes, but it can sometimes be an additional tool to help to diagnose shoulder disorders.

Abstract
OBJECTIVE To study changes in the reasons for third-trimester termination of pregnancy (TOP) for fetal anomalies over a 20-year period in France. STUDY DESIGN We compared a consecutive series of third-trimester TOPs from a single centre in 2005-2014 to those performed by Dommergues et al. in a similar centre in 1986-1994, using the same criteria. MAIN OUTCOME MEASURES The process leading to late TOP, using the same categories in both studies. RESULTS In the present series, 205 of 1409 TOPs were performed in the third trimester, vs. 305/956 in the historical series. There were 33 (16.1 %) diagnoses missed at the screening before the third trimester, 55 (26.8 %) cases in which the anomaly was impossible to diagnose until the third trimester, 86 (42 %) cases in which fetal prognosis could not be established until the third trimester despite earlier diagnosis, 31 (15.1 %) TOPs postponed to allow more time for the women/couples to contemplate, versus respectively 113 (37 %), 55 (18 %), 122 (40 %), and 15 (5%) in the historical series. CONCLUSION There was a significant drop in the rate of anomalies missed earlier. The increase in late TOP due to couples requiring additional time for contemplation might result from changes in counselling processes.

Abstract
Purpose This study aimed to explore the value of preoperative ultrasonography (US) in evaluating the peritoneal cancer index (PCI) of pseudomyxoma peritonei (PMP). Methods An ultrasound examination was performed on 59 patients with PMP before surgery, and the ultrasound PCI was evaluated. The accuracy of ultrasound PCI score was evaluated with the surgical PCI score as the gold standard. Results The preoperative ultrasound PCI was compared with the surgical PCI. The Spearman correlation coefficient of the total PCI score was 0.608 (P < 0.05). The difference in the Spearman correlation coefficient between the preoperative ultrasound PCI and the surgical PCI in areas 0–7 was statistically significant. (1) Among them, the total score and the correlation between 0–3 and 6 were higher. (2) Compared with the surgical PCI, overestimation (> 20%) was concentrated mainly in areas 2 and 4–8 for 2 points, and underestimation (< 20%) was concentrated mainly in areas 1, 3, 4, and 8 for 3 points. (3) The sensitivity and specificity of preoperative ultrasound for predicting the presence or absence of lesions were 85.7% and 50.0%, respectively. The sensitivity of LS 1, LS 2, and LS 3 was 31.7%, 48.2%, and 71.0%, respectively, and the specificity was 44.8%, 55.3%, and 58.8%, respectively. Conclusion The ultrasound examination can be used to score the preoperative PCI, judge the severity, and predict the prognosis in patients with PMP.

Abstract
Castration reduces aggressive and sexual behaviour and provides better carcass quality in bull calves. Vaccination against gonadotrophin-releasing hormone (GnRH) is used as an alternative to surgical castration for the purposes of reducing pain and distress in the animals. Currently, no anti-GnRH vaccine has been authorized for use in cattle in the European Union. The aim of the present study was to assess the effect of an anti-GnRH swine-specific vaccine (Improvac®, Zoetis, USA) on the morphology, structure and function of bull testes. Animals were vaccinated at days 1, 21 and 104 of the experimental period and were classified based on their live weight into the following two groups: LIGHT (172.9 ± 30.00 kg) and HEAVY (323.8 ± 37.79 kg). The scrotal circumference was measured on day 1 and prior to slaughter (day 164). At slaughter, the sperm motility and concentration in the caudae epididymis were assessed. Testes were weighed, measured and examined using ultrasound, and then tissue samples were collected and fixed in formalin. Histological and immunohistochemical studies were performed on the testes to measure the diameter of the seminiferous tubules and assess the testicular cell populations. The results revealed that suppression of testicular development was associated with the use of the Improvac® vaccine, which resulted in a smaller size of the testes and impaired spermatid production. However, the effect of Improvac® was more pronounced and consistent in calves vaccinated at a low live weight than at a heavy live weight, which suggested that vaccination is more effective when calves are vaccinated before or early during puberty. However, testes from calves vaccinated at a low live weight were more prone to the development of intraluminal concretions in the seminiferous tubules.

Abstract
OBJECTIVE Ultrasound estimation of foetal weight is a very important aspect of antenatal care. The role of amniotic fluid volume as a potential factor which may impede the relevance of ultrasonographic foetal weight estimation is still questionable. The aim of our study was to evaluate the impact of isolated oligohydramnios on the accuracy of ultrasound foetal weight estimation in at term pregnancies when examination was performed within 48 h before delivery. MATERIALS AND METHODS The retrospective cohort study included 1831 women with low-risk, singleton, at term pregnancy. Estimated foetal weight (EFW) was calculated using Hadlock-4 formula. Exclusion criteria consisted of multiple pregnancies, active phase of labour, preeclampsia, foetal growth restriction, foetal anomalies, gestational diabetes mellitus and the evidence of intrauterine infection. Isolated oligohydramnios was defined as Amniotic Fluid Index (AFI) ≤50 mm without any other foetal anomalies. EFW and actual birth weight (ABW) were compared by calculation of: absolute error (AE), absolute percentage error (APE) and substantial error (SE) = APE >10%. RESULTS Participants were divided into 2 groups: Group 1: patients with normal AFI (50 ≤ AFI ≤250 mm; n = 1602) and Group 2: (isolated oligohydramnios, n = 229). There were not observed statistically significant differences between mean ABW and mean EFW in both groups (Group 1: p = 0.525; Group 2: p = 0.317). Mean AE in Group 1 was 221.8 g and 223.1 g in Group 2 (p = 0.919). Mean APE was 6.54% and 6.64% in Group 1 and 2 respectively (p = 0.816). SE ratio was 21.9% in Group 1 and 19.2% in Group 2. Underestimation to overestimation ratio in Group 1 was 1.01 and 0.84 in Group 2. CONCLUSIONS Amniotic fluid volume has limited impact on ultrasound foetal weight estimation. In oligohydramnios group there might be a tendency of overestimation of neonatal ABW.

Abstract
Ultrasonography is the first-line imaging modality in the evaluation of the female pelvis in childhood and adolescence, because it is easy to perform, non-invasive and it does not require sedation. The transabdominal approach is preferred in children and adolescents, after filling the bladder to move away the bowel loops from the pelvis. The probe frequency must be adapted to age, thickness of tissues and depth of the structures under examination. High-frequency (4-12 MHz) linear or convex probes are used in newborns; high-frequency linear probes (4-12 MHz) in toddler, convex 5-7.5 MHz probes in girls and convex 3.5-5 MHz probes in teenagers. In this article, the main pathological conditions of the genital female tract in pediatric age are examined, such as congenital anomalies, disorders of sex development, ovarian cysts, ovarian tumors, adnexal torsion, primary amenorrhea, precocious puberty and pelvic inflammatory disease.

Abstract
Ultrasound (US) is the main imaging modality for the evaluation of pediatric patients with musculoskeletal diseases; particularly, it is an appropriate and reliable tool for diagnosis, follow-up and treatment of several musculoskeletal pathologies affecting the pediatric age. High-frequency (10-15 MHz) and high-resolution probes provide very lofty quality images, allowing a detailed study of the pediatric musculoskeletal system. Among the well-known advantages of this technique-such as the absence of ionizing radiations, its low cost and wide availability-US can as well rely on some intrinsic characteristics of the pediatric musculoskeletal system that can improve its diagnostic capability. The unossified portions of the pediatric skeleton and the absence of a thickened adipose tissue allow US to be highly effective and reliable in the study of muscles, tendons and cartilage. Lower-frequency sectoral transducers can be required in the study of some joints such as the shoulder or the hip, as well as in the examination of deep soft-tissue lesions. Furthermore, both color and spectral Doppler play an important role in the examination of soft-tissue lesions and synovial phlogosis. In this pictorial essay the main pathological conditions of pediatric musculoskeletal system will be examined, such as painful hip, evolutionary hip dysplasia, osteochondrosis, trauma-related pathologies and juvenile idiopathic arthritis.

Abstract
The neck structures are located very superficially and are therefore easy to explore by ultrasound examination. Ultrasonography is crucial for the detection of neck pathologies in children. High-frequency probes (10-15 MHz) are used for the ultrasound examination on the patient lying in supine decubitus and with their neck stretched out. The outcome of the exam depends mainly on the child's cooperation-hence the need for warm sonographic gel and a comfortable cushion to place under the patient's shoulders. The complete scan of the neck includes the evaluation of the thyroid and salivary glands and the vascular structures as well as the lymph node analysis. In children and adolescents, the thymus is often visualised in the supraclavicular and jugular scans. It appears as a structure, usually hypoechoic, with thin hyperechoic straps, though echogenicity increases with age. In this pictorial essay, the main pathological conditions of the neck in paediatric age will be examined, such as thyroid dysgenesis, thyroiditis, thyroid nodules, lymphadenopathies, cystic lesions, haemangiomas and vascular malformation, cervical thymus, fibromatosis colli and pilomatrixoma.

Abstract
BACKGROUND We systematically analyzed the extent of disease in unifocal invasive lobular carcinoma (ILC) using ultrasonography, with the histopathologic findings as the reference standard. PATIENTS AND METHODS In the present single-institution retrospective study, 128 cases of ILC were identified during a 5-year period. After exclusions, the analyzed cohort included 66 cases. Ultrasound measurements of the tumor extent along 3 axes were obtained. The tumor size was determined as the largest extent among the 3 axes and the tumor volume by ellipsoidal approximation. Pathology review provided the tumor size and volume. Correlation and regression analyses of tumor size and volume from the ultrasound and pathologic examinations were performed. The tumor stage from the ultrasound and pathologic examinations were used for the concordance analyses. RESULTS The median and quartiles (Q1, Q3) of tumor size from ultrasonography and pathology were 12.5 mm (Q1, 9 mm; Q3, 19 mm) and 17 mm (Q1, 12 mm; Q3, 25 mm), respectively. The corresponding data for tumor volume were 0.52 cm3 (Q1, 0.18 cm3; Q3, 1.92 cm3) and 1.04 cm3 (Q1, 0.45 cm3; Q3, 2.49 cm3). The ultrasound measurements correlated with the pathology-reported tumor size (Spearman ρ = 0.678; P < .0001) and volume (Spearman ρ = 0.699; P < .0001). The ultrasound-measured size and volume differed from the pathology-reported size and volume (P < .0001; Wilcoxon signed ranks test). Concordance between the clinical tumor size stage from ultrasound (cT) and pathology tumor size stage (pT) varied with the pT stage (P = .0003, Fisher's exact test), with the greatest concordance rate of 95.7% (95% confidence limit, 85.2%-99.5%) observed for pT1 tumors. CONCLUSION Ultrasonography underestimates the tumor size and volume, with the underestimation increasing for larger tumors. Hence, the concordance rate in tumor size stage between ultrasonography and pathology is tumor size dependent, with the greatest concordance rate observed for pT1 tumors.

Abstract
BACKGROUND/AIMS Goitre incidence in school-aged children evaluated using ultrasonography is one of the essential indicators of iodine intake in a given area. The aim of the study was to examine what the difference is between the volume of the thyroid gland measured in the supine and sitting position and to determine the intra-observer, inter-observer, and inter-position variations. METHODS The survey was conducted among 87 children (56 girls and 31 boys aged 7-13 years, mean age 10.44 ± 1.72 years). RESULTS The thyroid volume measured in a sitting position was significantly lower than that measured in the supine position. The intra-observer variations for the total thyroid volume equalled 9.56-9.65%. The inter-observer variations were significantly higher and amounted to 34.5-35.7%. CONCLUSIONS The way in which ultrasound evaluation is performed is important for the analysis of the results. It is crucial to aim for the smallest inter-observer variation, which can be achieved by strictly defining the methods of the thyroid measurement and comparing one's measuring techniques with the reference method. The use of standards in ultrasound evaluation performed in the supine position, as well as the use of standards without a strict determination of the study method, can lead to erro-neous conclusions.

Abstract
Objective: To investigate the correlation between ultrasonographic features of papillary thyroid carcinoma and central cervical lymph node metastasis. Methods: We retrospectively analyzed 486 patients with papillary thyroid carcinoma(PTC), pathologically confirmed after surgery in Tianjin Medical University Cancer Institute & Hospital. All patients were divided into central cervical lymph node metastasis group and non-metastasis group. No lateral cervical lymph node metastasis was found in preoperative ultrasonography and postoperative pathology. The characteristics of the ultrasound was observed and analyzed. Results: 297 out of 486 patients with papillary thyroid carcinomahad central metastasis, and the other 189 cases did not. Take pathology results as a standard, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy rate of preoperative ultrasound diagnosis in PTC patients with central cervical lymph node metastasis were 35.3%, 88.6%, 83.2%, 47.4%, 56.6%, respectively. Univariate analysis showed that multi-focus, taller-than-wide, diameter>1 cm, located in the lower pole, ill-defined margin, hypoechogenicity, micro-calcification, capsule invasion more than 1/4 perimeter of papillary thyroid carcinoma were significantly associated with central cervical lymph node metastasis (all P<0.05). Multivariate analysis showed that diameter>1 cm, micro-calcification, capsule invasion more than 1/4 perimeter of papillary thyroid carcinoma became independent risk factors of central cervical neck lymph node metastasis (all P<0.05). Conclusions: Preoperative description of ultrasonographical features has important value to assess central cervical lymph node metastasis in patients with papillary thyroid carcinoma. More information could be provided for clinical treatment. When the papillary thyroid carcinoma presented as diameter>1 cm, micro-calcification, and capsule invasion more than 1/4 perimeter of, there will be a greater risk of central cervical lymph node metastasis, and we shall suggest prophylactic central lymph cervical node dissection.

Abstract
Introduction Characterization of adnexal masses as benign or malignant is of utmost importance for optimal management and prognostication. Ultrasound examination plays an important role in the differentiation of adnexal masses. Various sonographic characteristics have been recognised to differentiate benign and malignant adnexal masses. Subjective evaluation of gray-scale ultrasound images by an experienced ultrasound examiner to discriminate adnexal masses is known as "pattern recognition". Aim To access the efficacy of pattern recognition at predicting an accurate histological diagnosis of adnexal masses. Materials and Methods All adnexal masses diagnosed clinically or during screening sonography were included in the study (n=136). Sonographic pattern recognition was performed and documented with specific diagnosis whenever feasible. Risk of Malignancy Index 3 (RMI3) score was also calculated. Results were compared with the gold standard histology. Chi-square test was used to assess the significance of the results and a p-value <0.05 was considered statistically significant. Results In the final cohort of 136 women, on pattern recognition, 91 were suspected to have benign adnexal masses and 45 were reported as malignant adnexal masses. However, on final histo-pathology, 94 patients had benign tumours and 42 patients had malignant disease. The benign group pattern recognition could render a specific diagnosis in 85.7% as compared to RMI3 pattern recognition conferred a sensitivity of 95.2% (RMI3 78.6%), with a slight compromise in the specificity (94.7% versus 96.8%). Conclusion Pattern recognition is a sensitive and specific sonographic tool in discriminating benign and malignant adnexal masses. Moreover, it is also useful in differentiating various benign adnexal masses.

Abstract
Ultrasound examinations are a standard procedure in the clinical diagnosis of many diseases. However, the efficacy of an ultrasound examination is highly dependent on the skill and experience of the operator, which has prompted proposals for ultrasound simulation systems to facilitate training and education in hospitals and medical schools. The key technology of the medical ultrasound simulation system is the probe tracking method that is used to determine the position and inclination angle of the sham probe, since this information is used to display the ultrasound images in real time. This study investigated a novel acoustic tracking approach for an ultrasound simulation system that exhibits high sensitivity and is cost-effective. Five air-coupled ultrasound elements are arranged as a 1D array in front of a sham probe for transmitting the acoustic signals, and a 5 × 5 2D array of receiving elements is used to receive the acoustic signals from the moving transmitting elements. Since the patterns of the received signals can differ for different positions and angles of the moving probe, the probe can be tracked precisely by the acoustic tracking approach. After the probe position has been determined by the system, the corresponding ultrasound image is immediately displayed on the screen. The system performance was verified by scanning three different subjects as image databases: a simple commercial phantom, a complicated self-made phantom, and a porcine heart. The experimental results indicated that the tracking and angle accuracies of the presented acoustic tracking approach were 0.7 mm and 0.5°, respectively. The performance of the acoustic tracking approach is compared with those of other tracking technologies.

Abstract
Simple radiography is the best diagnostic tool for rib fractures caused by chest trauma, but it has some limitations. Thus, other tools are also being used. The aims of this study were to investigate the effectiveness of ultrasonography (US) for identifying rib fractures and to identify influencing factors of its effectiveness. Between October 2003 and August 2007, 201 patients with blunt chest trauma were available to undergo chest radiographic and US examinations for diagnosis of rib fractures. The two modalities were compared in terms of effectiveness based on simple radiographic readings and US examination results. We also investigated the factors that influenced the effectiveness of US examination. Rib fractures were detected on radiography in 69 patients (34.3%) but not in 132 patients. Rib fractures were diagnosed by using US examination in 160 patients (84.6%). Of the 132 patients who showed no rib fractures on radiography, 92 showed rib fractures on US. Among the 69 patients of rib fracture detected on radiography, 33 had additional rib fractures detected on US. Of the patients, 76 (37.8%) had identical radiographic and US results, and 125 (62.2%) had fractures detected on US that were previously undetected on radiography or additional fractures detected on US. Age, duration until US examination, and fracture location were not significant influencing factors. However, in the group without detected fractures on radiography, US showed a more significant effectiveness than in the group with detected fractures on radiography (P=0.003). US examination could detect unnoticed rib fractures on simple radiography. US examination is especially more effective in the group without detected fractures on radiography. More attention should be paid to patients with chest trauma who have no detected fractures on radiography.

Abstract
OBJECTIVE To evaluate the efficacy of ultrasound-guided spinal nerve posterior ramus pulsed radiofrequency treatment for lower back post-herpetic neuralgia. MATERIALS AND METHODS 128 cases of lower back or anterior abdominal wall acute post-herpetic neuralgia patients were selected. They were randomly divided into two groups. Group A: oral treatment only with gabapentin + celecoxib + amitriptyline. Group B: while taking these drugs, patients were treated with radiofrequency (RF) pulses using a portable ultrasound device using the paravertebral puncture technique. In both groups, sudden outbreaks of pain were treated with immediate release 10mg morphine tablets. Visual analogue scale (VAS) was used for pain score, Pittsburgh Sleep Quality Index scale (PSQI) was used to evaluate sleep quality and morphine consumption were recorded at different time points, before and after treatment. Treatment efficiency was calculated while the occurrence of complications was documented. RESULTS At each time point after treatment, VAS scores were lower, but scores in the RF group was significantly lower than those of the oral-only group. In terms of sleep quality scores and morphine consumption between the two groups, the RF group was significantly lower than the oral-only group. During the procedure no error occurred with needle penetrating the abdominal cavity, chest, offal or blood vessels. CONCLUSIONS Ultrasound-guided spinal nerve posterior ramus pulsed radiofrequency treatment of lower back or anterior abdominal wall post-herpetic neuralgia proved effective by reducing morphine use in patients and led to fewer adverse reactions.

Abstract
Objective: To evaluate the diagnostic value of urinary protein and creatinine in combination with renal Doppler ultrasound examination in early renal damage of patients with hypertension. Methods: One hundred twenty two hypertensive patients who were treated in our hospital from December 2013 to June 2014 were selected for this study, including 33, 41 and 48 cases of Stage I, Stage II and Stage III hypertension respectively. Meanwhile, 30 healthy subjects were selected as the control group. They received urinary protein, creatinine and renal Doppler ultrasound examination. Results: The urinary protein levels of Stage I, II and Stage III hypertensive patients were significantly different from that of the control group (p<0.05). Urinary creatinine levels were similar (p>0.05) in stage I and II but different from control (p<0.05) in stage III. Doppler ultrasound examination showed that Stage I hypertensive patients had similar renal longest diameter (RLD), renal parenchymal thickness (RPT) and ratio of RPT/renal sinus thickness to those of the control group (p>0.05), and RLDs of Stage II hypertensive patients and the control group were not significantly different (p>0.05). Conclusion: Urinary protein and creatinine levels in combination with renal Doppler ultrasound examination could diagnose early renal damage in patients with hypertension.

Abstract
The aim of this study was to investigate the opinions of Swedish university students about information regarding soft markers, when observed at second trimester ultrasound screening. A cross-sectional survey, where 85 Swedish university students completed a study specific questionnaire containing eleven hypothetical scenarios, involving various parameters (disease/syndromes/malformations with different characteristics), and location of the markers. Almost all participants indicated that they would wish to be informed, prior to the ultrasound examination, about the assessment and significance of soft markers. However, the number of respondents who requested information about a potential actual finding was considerably less. Several participants wanted to be informed about detected markers associated to serious conditions but not when the marker indicated an increased risk for a treatable disease. Also, the specific location of the marker was of importance to the participants. The majority of respondents wished to be informed about the soft markers if they were observed in the heart or the brain of the foetus, compared to if they were located in the intestine or the skeleton. The students' opinion, in this study, implicate the importance of pre-examination information to enable expectant parents to make informed choice regarding the second trimester ultrasound screening as well as on reciving information of actual findings.

Abstract
Purpose To describe the incidence of unilateral congenital cataract associated with minimal (ultrasonically undetectable) levels of persistent fetal vasculature in the first 18 months of the life and to report surgical methods for intraocular lens implantation, using 25-gauge vitrectomy system. Methods Retrospective review was made on 16 consecutive patients with bilateral or unilateral congenital cataract in the first 18 months of the life who underwent surgery at Okayama University Hospital after the introduction of the 25-gauge vitrectomy system from October 2005 to March 2013. As the standard of care at this hospital in the study period, intraocular lenses were not implanted in children with bilateral cataract while intraocular lenses were implanted in those with unilateral cataract. Results Ten children with bilateral cataract underwent lensectomy in both eyes with a 25-gauge vitreous cutter under irrigation with a 25-gauge infusion cannula, inserted from two side ports at the corneal limbus. Six children with unilateral cataract underwent intraocular lens implantation and posterior capsulotomy after lens aspiration from limbal side ports. No patient showed vitreous abnormalities on ultrasound examinations before the surgery. At the surgery, all 10 children with bilateral cataract showed no additional abnormalities. In contrast, 3 children with unilateral cataract at the age younger than 12 months showed white fibrous tissue in the anterior vitreous integrated with the posterior lens capsule while the other 3 children with unilateral cataract at the age from 12 to 18 months did not have vitreous abnormalities. The fibrous tissue was cut together in the process of posterior capsulotomy from a 25-gauge trocar inserted at 1.5 mm posterior from the corneal limbus. Conclusions Unilateral congenital cataract in the first 12 months of the life has a high incidence for the association with anterior type of persistent fetal vasculature which could not be detected by preoperative ultrasound examinations. Intraocular lens implantation was technically feasible in unilateral cataract with or without minimal levels of persistent fetal vasculature in the first 18 months of the life.

Abstract
PURPOSE To assess the accuracy and ability of ultrasound for monitoring closed reduction for distal radius fractures. METHODS Consecutive patients undergoing ultrasound-guided closed reduction of acute, displaced distal radius fractures between January 2003 and December 2006 at our department were enrolled. The control group was extracted from patients who underwent a closed reduction for similar fractures under fluoroscopy or without any imaging assistance. To confirm the accuracy of the ultrasonography measurements, displacement distance values were compared with those on radiographic imaging before and after reduction. X-ray parameters for pre- and postreduction, reduction time, total cost, and success rate were compared between the ultrasound-guided and the control groups. RESULTS The ultrasound-guided group consisted of 43 patients (mean age, 68 y) and the control group consisted of 57 patients, which included 35 patients (mean age, 74 y) with fluoroscopic reduction and of 22 patients (mean age, 72 y) with reduction unaided by imaging. There were no significant displacement differences between radiographic and ultrasound measurements. In x-ray parameters for pre- and postreduction, there were no significant differences between the 2 groups. Ultrasound-guided reduction took longer than the other 2 methods. The success rate of the ultrasound and the fluoroscopic groups were similar (95% and 94%, respectively). CONCLUSIONS Our data suggest that ultrasound assistance can aid reduction of distal radius fractures as well as fluoroscopy. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic II.

Abstract
AIM: To investigate the clinical epidemiological characteristics and correlative factors of polypoid lesions of the gallbladder (PLG) in Qingdao, China.
METHODS: A total of 27 400 people who underwent health examination from January 2009 to December 2009 at our hospital were included in the study. Stratified random sampling was adopted to select 1 678 patients who were diagnosed with PLG by ultrasound to conduct an epidemiological survey, and 1 700 people without PLG were used as controls. Multifactor unconditional Logistic regression analyses were performed to investigate the relationship of life styles, behavior factors, blood sugar (FPG), triglycerides (TG), total cholesterol (CHO), fatty liver, cholecystitis and gallbladder stone with PLG. The clinical pathological characteristics and rationality of cholecystectomy were analyzed in 219 patients who had PLG with a diameter of >10 mm and underwent cholecystectomy.
RESULTS: Of 2 7400 people, 27 301 (99.64%) had complete data. The prevalence of PLG was 6.15% (1 678/27 301). The male to female ratio was 1.5:1. The majority (64.96%) of patients ranged in age between 30 and 59 years. Solitary PLG and multiple PLG accounted for 37.72% and 62.28%, respectively. The majority (86.95%) of PLG were smaller than 10 mm in diameter. Cholesterol polyps (CPs), benign non-CPs and malignant gallbladder diseases accounted for 79.14%, 17.76% and 3.10%, respectively. Multifactor unconditional Logistic regression analyses revealed that life styles, behavior factors, TG, FPG, and gallbladder stone had no significant association with PLG (all P > 0.05), while age, sex, CHO, fatty liver, and cholecystitis were significantly correlated with PLG (all P < 0.05). Of 219 (13.05%) patients who had PLG with a diameter of >10 mm and underwent cholecystectomy, 76.26% had benign PLG and 23.74% had malignant disease.
CONCLUSION: The incidence of PLG was 6.15% in Qingdao. Abnormal CHO metabolism, fatty liver and cholecystitis were correlative factors for PLG. Cholecystectomy should be cautiously selected in patients who had PLG with a diameter ≤10 mm.

Abstract
Limb-shaking transient ischemic attacks (TIA) may occur in patients with insufficient brain perfusion due to an underlying occlusive disease. We present the case of a 64-year-old patient who suffered from repetitive TIA presenting with shaking movements of the right-sided extremities and accompanying speech arrest. Symptoms are documented in the online supplementary video (www.karger.com/doi/10.1159/000327683). These episodes were frequently triggered in orthostatic situations. The diagnosis of limb-shaking TIA was established. The diagnostic workup revealed pseudo-occlusion of the left internal carotid artery, a poor intracranial collateral status and, as a consequence, an exhausted vasomotor reserve capacity. At ultrasound examination, symptoms were provoked by a change of the patient's position from supine to sitting. During evolvement of symptoms, a dramatic decrease of flow velocities in the left middle cerebral artery was observed. This case thus documents the magnitude and dynamics of perfusion failure in a rare manifestation of cerebral ischemic disease.

Abstract
Pigmented villonodular synovitis (PVNS) is characterized by hyperplasia of the synovial tissue in joints, of tendon sheaths, and of the mucous membranes, or fibrous tissue adjacent to the tendons. Its etiology is unknown. We report a case of diffuse intra-articular PVNS of the right knee in a 38-year-old man. Ultrasound and magnetic resonance imaging (MRI) features of the disease are described.

Abstract
Primary mesenteric lymphoma is a disease of the mesenteric lymph nodes that may represent a localized process or a component of a more disseminated pattern of disease.The case refers to a woman of 78 years, that was studied by ultrasound examination after accidental finding of abdominal mass. The examination confirmed the presence of the lesion; it defined the place (peritoneum) and the features (neoplastic lesion). Computer tomography (CT) confirmed the ultrasound diagnosis and showed an additional smaller lesion. The cytology exam from the CT biopsy showed to be a follicular lymphoma B. This case confirms the ultrasound examination role in the study of peritoneal lesions and underlines how a proper diagnostic process is essential for therapy.
