Time Trends Analysis of Cervical Cancer Incidence in Cluj County, Romania, Using Data from a Population-Based Cancer Registry.

(1) Background: Romania has one of the highest cervical cancer incidence rates in Europe. In Cluj County, the first screening program was initiated in 1998. We aimed to investigate the time trends of cervical cancer incidence in women from Cluj County and to evaluate the data quality at the Cancer Registry. (2) Methods: We calculated time trends of standardized incidence rates in the period 1998-2014 and the Annual Percent Change (APC%). To assess data quality, we used the indicators: mortality/incidence ratio (M/I), percentage of cases declared only at death (DOD%), and percentage of cases with pathological confirmation (PC%). (3) Results: The standardized incidence rate increased steadily, from 23.74 cases/100,000 in 1998, to 32/100,000 in 2014, with an APC% of 2.49% (p < 0.05). The rise in incidence affected both squamous cell carcinoma (APC% 2.49%) (p < 0.05) and cervical adenocarcinoma (APC% 10.54%) (p < 0.05). The M/I ratio was 0.29, DOD% 2.66%, and MC% 94.8%. The last two parameters are within the silver standard concerning data quality. (4) Conclusions. Our study revealed an ascending trend of cervical cancer incidence, more consistent for adenocarcinoma, in the context of a newly introduced screening program and partially due to the improvement of the quality of case reporting at the Cancer Registry from Cluj.

Comparison of Hystero-salpingography and Hysterosalpingo-Contrast Sonography for tubal patency testing: technical success, pain perception, side effects and complications.

AIMS: The aim of this study was to compare technical success and tolerability between hysterosalpingography (HSG) and hysterosalpingo-contrast ultrasonography (HyCoUs) as a first-line evaluation method in a single fertility center. MATERIAL AND METHODS: The study included 56 infertile women: 27 patients underwent HSG and 29 patients underwent HyCoUs. Pain perception was measured by means of an 11-point visual analog scale (VAS) and the Stacy score. Side-effects, technical aspects, complications and variable correlations were documented. RESULTS: The median VAS scale was 5 (4;6) for HSG and 1 (1;2) for HyCoUs. The median Stacy score was 2 (1;3) for HSG and 1 (0;1) for HyCoUs. The difference in pain perception was statistically significant for both pain scores (p<0.001). All patients undergoing HyCoUs reported a visual analog (VAS) pain score of <5 and 59.3% of patients undergoing an HSG reported a score of >5. Increased pain scores showed a statistically significant association with duration and total volume of substance infused. The type of procedure and volume infused were independently associated with the VAS scale. In the HSG group, 14.8% (4) of patients reported a vagal effect (p<0.001), one patient requiring hospitalization. No vagal effects were reported following HyCoUs and the method was technically successful in 100% (29) of cases. HSG was successful in 88.9% (24) of cases. CONCLUSIONS: HyCoUs is a well-tolerated procedure with reduced frequency of adverse effects. Low pain perception is strongly correlated with a low volume infused. It is non-invasive and efficient in rendering good quality images.

Retrograde urethrosonography with SonoVue in strictures of the male urethra: a pilot study.

AIM: To evaluate the effectiveness of SonoVue urethrosonography in diagnosing the adult male anterior urethral strictures pathology in comparison with retrograde urethrography. MATERIAL AND METHOD: We standardised the method and performed a comparative study evaluating the diagnosis of urethral strictures using retrograde urethrography and retrograde ultrasonographic exploration with SonoVue on 6 male patients. RESULTS: In all patients, the existence of urethral stricture, localization and its extension were confirmed. Contrast-enhanced ultrasonographic exploration brought additional categories of information: the degree of spongiofibrosis, the elasticity of the urethral walls and the presence of urethral lithiasis. There were no periprocedural incidents. CONCLUSION: This pilot study demonstrates the feasibility and innocuity of urethral ultrasound with SonoVue. Real-time ultrasound exploration highlights aspects that are not seen in radiological examination, so the method can be complementary or alternative to this procedure.

Diagnostic challenges in non-cirrhotic portal hypertension - porto sinusoidal vascular disease.

Non-cirrhotic portal hypertension consists of a group of diseases characterized by signs and complications of portal hypertension, which differ from cirrhosis through histological alterations, hemodynamic characterization and, clinical outcome. Because of the similarities in clinical presentation and imaging signs, frequently these patients, and particularly those with porto-sinusoidal vascular disease (PSVD), are misdiagnosed as having liver cirrhosis and thus raising difficulties in their diagnosis. The most challenging differentiation to be considered is between PSVD and cirrhosis and, although not pathognomonic, liver biopsy is still the standard of diagnosis. Although they still require extended validation before being broadly used, new non-invasive methods for the diagnosis of porto-sinusoidal vascular disease, like transient elastography, contrast-enhanced ultrasound or metabolomic profiling, have shown promising results. Another issue is the differentiation between PSVD and chronic extrahepatic portal vein obstruction, especially now when it is known that 40% of patients suffering from PSVD develop portal vein thrombosis. In this particular case, once the portal vein thrombosis occurred, the diagnosis of PSVD is impossible according to the current guidelines. Moreover, so far, the differentiation between PSVD and sinusoidal obstruction syndrome has not been clear so far in particular circumstances. In this review we highlighted the diagnostic challenges regarding the PSVD, as well as the current techniques used in the evaluation of these patients.

Contrast-enhanced ultrasonography in the initial evaluation of the kidney graft function: a pilot study.

AIM: Our study aimed to assess the usefulness of contrast-enhanced ultrasound (CEUS) in the initial evaluation of the graft function. MATERIALS AND METHOD: A cross-sectional study was conducted in the early postoperative period on patients with kidney transplantation, between September 2017 to November 2018. Two groups of patients were investigated; delayed graft function (DGF) and early graft function (EGF). All patients were examined by grey scale, Doppler ultrasound and CEUS. RESULTS: Nineteen patients, aged from 23 to 64 years (mean age 50 years), 7 in the DGF group and 12 in the EGF group were evaluated. The resistive index (RI) show significantly higher values in the DGF group at the level of upper interlobar artery (p=0.025) and medium interlobar artery (p=0.02). The CEUS investigation shows a greater region of interest (ROI) area (p=0.02) and lower values for wash-out area under the curve (WoAUC) (p=0.047) and respectively wash-in and wash-out area under the curve (WiWoAUC) (p=0.031) for the DGF group. The quality of fit (QoF) proved lower in the DGF group either for evaluation of global graft (p=0.012), cortex (p=0.025), or medulla (p=0.009).A significant relationship among all patients was found between the glomerular filtration rate (GFR) [ml/min] and the renal artery fall time (FT) [s] (p=0.012), WoAUC [a.u.] (p=0.03), and WiWoAUC [a.u.] (p=0.024). The arterial QoF [%] was associated with the arterial ROI area (p=0.048). CONCLUSIONS: Intensity CEUS parameters WoAUC and WiWoAUC may be useful to diagnose and follow-up grafts with delayed function. Additional studies on larger cohorts are required for the recommendation of CEUS as a routine evaluation of the transplanted kidney.

Difficulties in diagnosing HIV-associated nephropathy in kidney transplanted patients. The role of ultrasound and CEUS.

A 62-year-old woman who underwent kidney transplantation in 2014 was diagnosed with HIV infection in 2018. Grey scale and Doppler ultrasound evaluation revealed a normal aspect of the allograft. Contrast-enhanced ultrasound detected a quick cortical contrast uptake followed by a rapid cortical wash-out. This behavior was interpreted as a sign of inflammation. Ten months after ultrasound evaluation the graft presented severe disfunction and the patient was reintroduced into the hemodialysis program.

Ultrasound as the first imaging method in severe lung disease. Considerations about a case of pulmonary tuberculosis and review of the literature.

Abdominal ultrasound (US) performed as a "primary imaging procedure" is an important diagnostic tool in gastroenterol-ogy. Expanding the routine investigation to the lower thoracic region might sometimes accelerate the diagnosis in inconclusive manifestations such as pulmonary pathology.US is a valuable tool in evaluating patients with breathing difficulties, chest pain, hypoxia, or chest trauma. This paper presents the particular situation of a patient hospitalized in the gastroenterology depart-ment, where the US identified significant pulmonary alterations and changed the final diagnosis from a gastrointestinal disease to pleuro-pulmonary tuberculosis. A brief review of literature is also included, in relation to chest US.

Shear-Wave Elastography Variability Analysis and Relation with Kidney Allograft Dysfunction: A Single-Center Study.

Shear-wave elastography (SWE) showed the absence or presence of significant differences among stable kidney allograft function and allograft dysfunction. We evaluated the variability of kidney allograft stiffness in relation to allograft dysfunction, respectively, in terms of a correlation of stiffness with patients' characteristics. A single-center prospective study on patients who had undergone renal transplantation was conducted between October 2017 and November 2018. Patients were clinically classified as having a stable allograft function or allograft dysfunction. SWE examinations performed by the same radiologist with a LOGIQ E9 were evaluated. Ten measurements were done for Young's modulus (kPa) at the level of allograft cortex and another ten at the level of medulla. Eighty-three SWE examinations from 63 patients, 69 stable allografts, and 14 allografts with dysfunction were included in the analysis. The intra-examinations stiffness showed high variability, with the quantile covariation coefficient ranging from 2.21% to 45.04%. The inter-examinations stiffness showed heterogeneity (from 28.66% to 42.38%). The kidney allograft cortex stiffness showed significantly higher values in cases with dysfunction (median = 28.70 kPa, interquartile range (IQR) = (25.68-31.98) kPa) as compared to those with stable function (median = 20.99 kPa, interquartile range = (16.08-27.68) kPa; p-value = 0.0142). Allograft tissue stiffness (both cortex and medulla) was significantly negatively correlated with body mass index (-0.44, p-value < 0.0001 for allograft cortex and -0.42, p-value = 0.0001 for allograft medulla), and positively correlated with Proteinuria/Creatinuria ratio (0.33, p-value = 0.0021 for allograft cortex and 0.28, p-value = 0.0105 for allograft medulla) but remained statistically significant only in cases with stable function. The cortical tissue stiffness proved significantly higher values for patients with allograft dysfunction as compared to patients with stable function, but to evolve as an additional tool for the evaluation of patients with a kidney transplant and to change the clinical practice, more extensive studies are needed.

With this case report, we highlight the role of abdominal ultrasound in the management of elderly patientswith gallstone ileus (a rare cause of intestinal obstructions caused by a cholecysto-duodenal fistula) and with contraindications for contrast-enhanced CT scan.

Inter-operator variability and source of errors in tumour response assessment for hepatocellular carcinoma treated with sorafenib.

OBJECTIVES: To assess the inter-operator concordance and the potential sources of discordance in defining response to sorafenib in hepatocellular carcinoma (HCC). METHODS: All patients who received sorafenib between September 2008 and February 2015 were scrutinised for this retrospective study. Images were evaluated separately by three radiologists with different expertise in liver imaging (operator 1, >10 years; operator 2, 5 years; operator 3, no specific training in liver imaging), according to: response evaluation radiological criteria in solid tumours (RECIST) 1.1, modified RECIST (mRECIST) and response evaluation criteria in cancer of the liver (RECICL). RESULTS: The overall response concordance between the more expert operators was good, irrespective of the criteria (RECIST 1.1, ĸ = 0.840; mRECIST, ĸ = 0.871; RECICL, ĸ = 0.819). Concordance between the less expert operator and the other colleagues was lower. The most evident discordance was in target lesion response assessment, with expert operators disagreeing mostly on lesion selection and less expert operators on lesion measurement. As a clinical correlate, overall survival was more tightly related with "progressive disease" as assessed by the expert compared to the same assessment performed by operator 3. CONCLUSIONS: Decision on whether a patient is a responder or progressor under sorafenib may vary among different operators, especially in case of a non-specifically trained radiologist. Regardless of the adopted criteria, patients should be evaluated by experienced radiologists to minimise variability in this critical instance. KEY POINTS: • Inter-operator variability in the assessment of response to sorafenib is poorly known. • The concordance between operators with expertise in liver imaging was good. • Target lesions selection was the main source of discordance between expert operators. • Concordance with non-specifically trained operator was lower, independently from the response criteria. • The non-specifically trained operator was mainly discordant in measurements of target lesions.
