RESUMO
PURPOSE: To investigate the concordance of biopsy and pathologic International Society of Urological Pathology (ISUP) grading in salvage radical prostatectomy (SRP) patients for recurrent prostate cancer. METHODS: Within a high-volume center database, we identified patients who underwent SRP for recurrent prostate cancer (PCa) between 2004 and 2020. Upgrading, downgrading, concordance, and any discordance between posttreatment biopsy ISUP and ISUP at SRP were tested. Logistic regression models were used to predict ISUP upgrading and ISUP discordance. Models were adjusted for prostatic specific antigen before SRP, age at surgery, initial prostatic specific antigen (PSA), type of primary treatment, time from primary PCa diagnosis to SRP, number of positive cores at biopsy, and original Gleason score. RESULTS: Overall, 184 patients with available biopsy and pathologic ISUP grading were identified. Of those, 17.4% (n = 32), 40.8% (n = 75), 19.6% (n = 36), and 22.2% (n = 41) harbored biopsy ISUP 1, ISUP 2, ISUP 3, and ISUP 4-5 grading, respectively. Pathologic ISUP 1, ISUP 2, ISUP 3, and ISUP 4-5 grading was recorded in 6.0% (n = 11), 40.8% (n = 75), 32.1% (n = 59), and 21.2% (n = 39), respectively. Median PSA before SRP was 5.5 ng/ml (interquartile range [IQR]: 3.1-8.1 ng/ml), median age at SRP was 65.1 years (IQR:60.7-69.4 years) and median time from original PCa diagnosis to SRP was 47 months (IQR: 27.3-85.2 months). Concordance of biopsy and pathologic ISUP was identified in 45.1% (n = 83). Conversely, any ISUP discordance, upgrading and downgrading of at least one ISUP group was identified in 54.9% (n = 101), 35.3% (n = 65), and 19.6% (n = 36). In logistic models, none of the preoperative characteristics was associated with upgrading or ISUP discordance (all p > 0.1). CONCLUSION: Discordance between biopsy and pathologic ISUP grading is common at SRP. However, in 45% of SRP cases biopsy ISUP is capable to predict pathologic ISUP. Further studies are necessary to identify characteristics for ISUP upgrading at SRP.

PURPOSE: Positive surgical margins (PSM) represent a poor prognostic factor at radical prostatectomy (RP). To investigate the impact of PSM, its length, the focality and the Gleason grade at the PSM, on the oncologic outcomes in nonorgan-confined RP patients. METHODS: Within a high-volume center database, we identified patients who harbored non-organ-confined (pT3) prostate cancer (PCa) at RP between 2010 and 2016. Only patients without lymph node invasion were included. Kaplan-Meier analyses and multivariable Cox regression models were used to test the effect of PSM on biochemical recurrence (BCR), metastasis, and cancer-specific death after RP in patients without adjuvant radiotherapy. RESULTS: Overall, 3705 patients were identified. Of those, 27.2% (n = 1007) harbored PSM. At 96 months after RP, BCR-free, metastasis-free and cancer-specific survival was 41.6 versus 57.5%, 82.7 versus 88.6%, and 94.7 versus 98.5% for patients with versus without PSM (all p < 0.001). BCR-free, metastasis-free and cancer-specific survival rates at 96 months were 56.7 versus 26.5% (p < 0.001), 94.4 versus 67.4% (p < 0.001), and 100.0 versus 87.1% (p < 0.01) for Gleason pattern 3 versus ≥ 4 at the margin and 45.0 versus 27.8% (p < 0.01), 83.3 versus 82.3% (p = 0.2), and 95.2 versus 92.7% (p = 0.3) for <4 mm versus ≥4 mm length of margin. In multivariable Cox models PSM was an independent predictor for BCR (hazard ratio [HR]:1.53, p < 0.001) and cancer-specific death (HR:2.75, p = 0.02). In subgroups of patients with PSM only, Gleason ≥ 4 at the margin (HR:1.60, p < 0.01) and length of PSM (HR:1.02, p < 0.05) was an independent predictor of BCR. CONCLUSION: PSM represents an independent predictor for worse oncologic outcome in nonorgan-confined PCa at RP. Gleason ≥ 4 at the margin was associated with the development of BCR, metastasis, and with cancer-specific death after RP. Next to margin status, Gleason at the margin and its length carry important information that should be reported for the specimen.

BACKGROUND: Positive surgical margins (PSMs) represent a poor prognostic factor at radical prostatectomy (RP). To investigate the impact of PSM, its length, the focality, and the PSM Gleason, on biochemical recurrence (BCR) in organ-confined RP patients. METHODS: Within a high-volume center database, we identified patients who harbored organ-confined (pathologic stage T2 disease) prostate cancer (PCa) at RP (2010-2016). Kaplan-Meier analyses and multivariable Cox regression models were used to test the effect of the PSM on the BCR risk. RESULTS: Overall, 8770 patients were identified. Of those, 6.6% (n = 579) harbored PSM. BCR-free survival at 72 months after RP was 77.7% vs 89.0% for patients with vs without PSM (P < .001). BCR-free survival rates at 72 months were 77.4% vs 73.6% (P = .1) for unifocal vs multifocal PSM, 77.2% vs 71.8% (P = .03) for Gleason pattern 3 vs ≥4 at the margin and 88.4% vs 66.3% (P < .001) for <3 vs ≥3 mm length of margin. In multivariable Cox models PSM was an independent predictor for BCR (hazard ratio [HR] = 2.40, P < .001). However, in subgroups with PSM, only ≥3 mm PSM represented an independent predictor (HR = 1.93, P = .04), while focality and Gleason at the margin were no significant predictors. CONCLUSION: PSM represents an independent predictor for BCR in organ-confined PCa at RP. Moreover, Gleason ≥4 at the margin and ≥3 mm PSM length were associated with worse BCR-free survival. Closer surveillance of patients with organ-confined PCa at RP and PSM can help to identify those who qualify for early salvage radiotherapy.

PURPOSE OF REVIEW: To provide a summary of surgical outcomes in percutaneous nephrolithotomy (PCNL) according to various techniques and tract sizes. RECENT FINDINGS: Recent literature in this field concluded that standard PCNL (sPCNL) remains the optimal treatment for stones between 1 and 2.5âcm and can be managed with tracts 14-20âF, whereas small stones less than 1.5âcm can be treated with tracts under 14âF. According to new datasets, smaller tracts can be equally effective in the treatment and might offer the possibility to reduce bleeding, length of hospital stay, postoperative pain as well as overall complication rates when compared with sPCNL. On the other hand, longer operative time as well as lower stone-free rates, which have been the main drawbacks of the miniaturized approach, have recently shown to be comparable with sPCNL. SUMMARY: At present, tract size is a highly debatable topic in percutaneous stone therapy. New systems for miniaturized PCNL have been developed to achieve comparable stone-free rates while reducing the incidence of common complications. The adoption of these techniques demands skilled surgeons and institutional investment for the acquisition of new equipment.

OBJECTIVE: Report our experience of the management of a patient with undiagnosed retroperitoneal paraganglioma and the intraoperative complications that the theatre team faced. CASE REPORT: We present a case of a 36-year-old patient who during oncological follow-up for a previous diagnosis of parotid acinar cell carcinoma was incidentally identified as having an interaortocaval tumour. Following routine preoperative assessment the patient was arranged to undergo a laparoscopic retroperitoneal tumour resection. After minimal tumour manipulation the patient developed cardiac rhythm abnormalities and became hypertensive. The tumour was successfully removed laparoscopically after a cautious inter- aortocaval dissection. Abruptly, prior to extraction of the tumour containing endobag, the patient developed cardiac arrest. Following 35 minutes of life support measures there was a return of spontaneous circulation. The endobag was laparoscopically removed from the abdominal cavity 24 hours later using the initial operative port sites. The patient´s progression was satisfactory and he could be discharged six days postoperatively. CONCLUSIONS: Asymptomatic undiagnosed paragangliomas represent a real challenge during laparoscopic operations. Haemodynamic changes and life-threatening events can arise acutely intraoperatively, where an immediate and coordinated response of the whole theatre team may be required to avoid fatal outcome.

OBJECTIVE: To determine the impact of imperative or elective indications on the perioperative, functional and oncological outcomes of patients undergoing robot-assisted partial nephrectomy. METHODS: Between June 2006 and September 2016, data of patients who underwent robot-assisted partial nephrectomy at the Onze-Lieve-Vrouwziekenhuis Hospital in Aalst, Belgium, were retrospectively reviewed from a prospectively collected database. Only patients with non-metastatic, clinical T1-T2 graded tumors were included. Perioperative, functional and oncological outcomes were recollected. A comparative analysis was carried out after dividing patients into two groups: those who underwent robot-assisted partial nephrectomy for an elective indication (group 1, n = 194), and for an imperative indication (group 2, n = 57) caused by a solitary kidney (n = 20), impaired renal function (n = 2) or both (n = 35). RESULTS: Patients in group 2 were older (74 vs 71 years, P < 0.001), and had a higher Charlson Comorbidity Index (P < 0.001) and American Society of Anesthesiologists score (P < 0.001). No differences were observed concerning laterality, sex, preoperative aspects and dimensions used for an anatomical score or clinical stage. Surgical outcomes considering estimated blood loss, surgical time, ischemia time and transfusion rate showed no significant difference between groups. The complication rate according to Clavien-Dindo showed no difference between groups (P = 0.6). No difference was found between groups with regard to percentage decrease of estimated glomerular filtration rate (7.4 vs 4.8%, P < 0.15). CONCLUSIONS: Robot-assisted partial nephrectomy can be safely and effectively carried out by experienced surgeons in a high-volume center with similar perioperative, functional and oncological outcomes for both elective or imperative indications.

CONTEXT: Although miniaturized percutaneous nephrolithotomy (mPCNL) and retrograde intrarenal surgery (RIRS) are both options for treating >1cm kidney stones, controversies exist on whether one is more effective and safer than the other. OBJECTIVE: To systematically appraise randomized trials comparing the effectiveness and safety of mPCNL and RIRS for treating >1cm kidney stones. EVIDENCE ACQUISITION: A systematic search on PubMed/Medline, Web of Science, Embase, and ClinicalTrials.gov was conducted in August 2020 following the Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA). Randomized trials comparing mPCNL and RIRS for >1cm kidney stones, and reporting stone-free rate (SFR), hemoglobin drop, transfusion rate, length of hospital stay (LOS), and/or complications, were included. EVIDENCE SYNTHESIS: Eight studies compared mPCNL and RIRS, but one was not included due to its high risk of bias. SFR was higher for mPCNL (RR: 1.06 [95% coefficient interval {CI}, 1.01-1.10], p=0.008). Hemoglobin drop was higher for mPCNL (mean difference [MD]: 0.35 [95% CI, 0.05-0.65] g/dl, p=0.02); however, transfusion rates were similar (p=0.44). Complication rate was similar between mPCNL and RIRS (p=0.39), and the LOS was higher for mPCNL (MD: 1.11 [95% CI, 0.06-2.16] d, p=0.04). A subgroup analysis of lower pole stones showed that SFR was higher for mPCNL (RR: 1.09 [95% CI, 1.00-1.19], p=0.05). CONCLUSIONS: Both approaches are effective and safe. Among these approaches, mPCNL has a higher SFR than RIRS for overall >1cm renal and lower pole stones, but longer LOS, and a higher hemoglobin drop that does not translate into higher transfusion rates. Complications are comparable. PATIENT SUMMARY: Randomized trials have evaluated whether miniaturized percutaneous nephrolithotomy (mPCNL) or retrograde intrarenal surgery is more effective and safer for treating >1cm stones. After comparing the stone-free rate, hemoglobin drop, transfusion rate, length of hospital stay, and complications between both the approaches, mPCNL was found to be slightly more effective, but both were equally safe.

Radiomics texture analysis offers objective image information that could otherwise not be obtained by radiologists' subjective radiological interpretation. We investigated radiomics applications in renal tumor assessment and provide a comprehensive review. A detailed search of original articles was performed using the PubMed-MEDLINE database until 20 March 2020 to identify English literature relevant to radiomics applications in renal tumor assessment. In total, 42 articles were included in the analysis and divided into four main categories: renal mass differentiation, nuclear grade prediction, gene expression-based molecular signatures, and patient outcome prediction. The main area of research involves accurately differentiating benign and malignant renal masses, specifically between renal cell carcinoma (RCC) subtypes and from angiomyolipoma without visible fat and oncocytoma. Nuclear grade prediction may enhance proper patient selection for risk-stratified treatment. Radiomics-predicted gene mutations may serve as surrogate biomarkers for high-risk disease, while predicting patients' responses to targeted therapies and their outcomes will help develop personalized treatment algorithms. Studies generally reported the superiority of radiomics over expert radiological interpretation. Radiomics provides an alternative to subjective image interpretation for improving renal tumor diagnostic accuracy. Further incorporation of clinical and imaging data into radiomics algorithms will augment tumor prediction accuracy and enhance individualized medicine.
RESUMO
BACKGROUND: The unexpected coronavirus disease 2019 (COVID-19) pandemic has spread worldwide rapidly, developing into a global health crisis. At the same time, it has seriously impacted the daily activities in all the fields of urology. OBJECTIVE: To better understand the impact of the COVID-19 pandemic on clinical, academic, and scientific activities as well as on the quality of life of urologists from the main centers in Europe. DESIGN SETTING AND PARTICIPANTS: We conducted a survey using a 37-item questionnaire. The survey included three main sections: clinical practice, academic/scientific activities, and personal/social quality of life. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: A descriptive analysis was performed using the collected data. RESULTS AND LIMITATIONS: A total of 107 representatives affiliated to different centers from 22 countries completed the survey. Clinical activities were affected in 54.2% of the centers, and 85.0% of the elective surgeries were cancelled. Of the urological departments, 64.5% were still performing minimally invasive surgery for malignant disease. In 33.6% of the hospitals, dedicated and specially equipped operating theaters for COVID-19-positive patients were not available. According to 72.9% of participants, COVID-19 had a substantial negative impact on academic activities, and 82.3% of the respondents agreed that their quality of life has been affected negatively by the pandemic. Finally, 92.5% of the participants believe that the pandemic will have a moderate to severe impact on the health system of their countries. CONCLUSIONS: Data collected in this survey provide insight into changes brought about in clinical and academic settings amid COVID-19. Along with shortages such as bed occupancy and personal protective equipment, it highlights negative impacts on academic and scientific activities, including the personal and social life of urologists. PATIENT SUMMARY: It is essential to understand the impact of the coronavirus disease 2019 (COVID-19) pandemic on clinical, academic, and scientific urological activities, as well as on related personal and social issues.
RESUMO
BACKGROUND: To examine the impact of different pretreatment definitions on biochemical recurrence (BCR)-free survival, metastasis-free survival, and cancer-specific survival after radical prostatectomy. METHODS: Overall, 26,364 patients with clinically localized disease who underwent radical prostatectomy at a single institution (1992-2017) were retrospectively analyzed. Seven pretreatment definitions of high-risk CaP (prostate-specific antigen [PSA] ≥20 ng/ml, clinical stage ≥T2c, clinical stage T3 [cT3], biopsy Gleason score [GS] 8-10 [Grade Group {GG} IV-V], biopsy GS 9 to 10 [GG V], D'Amico risk definition, National Comprehensive Cancer Network risk definition) were evaluated. Kaplan-Meier, as well as multivariable Cox regression analyses were used. RESULTS: Depending on the definition, patients with high-risk CaP comprised between 0.9% (cT3) and 20.3% (D'Amico high-risk) of the population. Ten-year BCR-free survival rates varied from 36.0% (≥cT2c) to 47.4% (National Comprehensive Cancer Network high-risk). Ten-year metastasis-free survival rates varied from 56.6% (GS 9-10/GG V) to 77.5% (PSA ≥ 20 ng/ml). Ten-year cancer-specific survival rates varied from 86.6% (cT3) to 94.5% (PSA ≥ 20 ng/ml). In multivariable analysis, all high-risk definitions were associated with significantly higher risk of BCR (hazard ratio [HR]: 3.4-3.9), metastatic progression (HR: 3.9-8.8), and cancer-specific mortality (HR: 2.8-11.2). CONCLUSIONS: Variety in outcomes exists, depending on the pretreatment definition of high-risk CaP. Among the tested, GS 9 to 10 (GG V), cT2c, and cT3 were the strongest predictor for higher BCR risk, cT3 was the strongest predictor for higher metastatic progression risk and GS 9 to 10 (GG V) was the strongest predictor for higher cancer-specific mortality risk in multivariable analyses.

OBJECTIVES: Previous studies reported improved continence recovery by bladder neck sparing (BNS) in prostate cancer patients treated with robot-assisted laparoscopic radical prostatectomy (RALP), without compromising biochemical recurrence (BCR). We compared the continence outcomes, surgical margin rates, and BCR risk of BNS vs. bladder neck reconstruction (BNR) patients during RALP. METHODS: Overall, 1,512 patients who underwent RALP with BNS or BNR between 2010 and 2017 in a single high-volume center, were identified. Logistic regression models tested the effect of BNS on continence and surgical margin rates. Cox regression models tested the effect of BNS on BCR. Continence was defined as the use of 0 or 1-safety pad per day. RESULTS: Three hundred and eighty-two vs. 1,130 patients underwent BNS vs. BNR. The median time to catheter removal was significantly shorter (5 vs. 8 days) in patients with BNS. Pad-free rates at 7 days after catheter removal were 60.0% vs. 54.5%, continence rates were 80.1% vs. 78.3% after 3 months and 85.3% vs. 89.6% after 1 year for BNS and BNR, respectively. Multivariable models revealed that BNS is an independent predictor to be pad-free at 7 days after catheter removal (OR: 1.39, Pâ¯=â¯0.04), but no predictor for continence at 3 months (OR: 1.02, Pâ¯=â¯0.9) and 1 year (OR: 0.78, Pâ¯=â¯0.4) after RALP, as well as for positive surgical margin (OR: 0.95, Pâ¯=â¯0.8) and BCR (Hazard ratio: 0.95, Pâ¯=â¯0.9). CONCLUSION: Patients with BNS had a better chance to be pad-free at 7 days after catheter removal and had a significant shorter time to catheter removal. However, this beneficial effect disappeared with time and no differences in continence rates at 3 months and 1 year were recorded. Moreover, BNS did not negatively affect positive margin or BCR rates.

BACKGROUND: To analyze oncological outcomes of very high-risk patients with initial PSA 50-99.9 and ≥100 ng/ml who underwent radical prostatectomy (RP) for clinically localized prostate cancer. METHODS: Overall, 2,811 RP patients (1992-2018) with negative preoperative CT-scan and bone scintigraphy were included. The impact of preoperative PSA level, categorized as 20-49.9 (nâ¯=â¯2,195) vs. 50-99.9 (nâ¯=â¯454) vs. ≥100 ng/ml (nâ¯=â¯162) on biochemical recurrence (BCR)-free survival, metastasis-free survival (MFS) and cancer-specific survival (CSS) was assessed using Kaplan-Meier and multivariable Cox regression models. RESULTS: Median follow-up was 47.5 months. Ten-year BCR-free survival rates were 46.9 vs. 32.1 vs. 29.0% within PSA-categories 20-49.9 vs. 50-99.9 vs. ≥100 ng/ml, respectively (P < 0.001). Ten-year MFS rates were 78.4 vs. 67.2 vs. 37.3% within PSA-categories 20-49.9 vs. 50-99.9 vs. ≥100 ng/ml (P < 0.001). 10-year CSS rates were 93.7 vs. 85.5 vs. 66.7% within PSA-categories 20-49.9 vs. 50-99.9 vs. ≥100 ng/ml (P < 0.001). In multivariable analyses, PSA-categories 50-99.9 ng/ml and ≥100 ng/ml were independently predicting higher risk of BCR (hazard ratio [HR]: 1.3 and 1.4), metastatic progression (HR: 1.4 and 2.3), and cancer-specific mortality (CSM, HR: 1.9 and 3.4) compared with PSA-category 20-49.9 ng/ml. CONCLUSION: Initial PSA levels ≥50 ng/ml are associated with higher risk of BCR, metastatic progression, and CSM compared with high-risk patients with PSA of 20-49.9 ng/ml. In consequence, these patients may be counseled about a potentially increased risk of undetected metastases prior to RP possibly necessitating intensified multimodal treatments in the future.

The Spanish version of the Wisconsin Stone Quality of Life (WISQOL) questionnaire was developed and validated. A double-back translation of the WISQOL was conducted and syntactic amendments were made, resulting in the Spanish version of the WISQOL (S-WISQOL) which then went through a readability analysis. Stone formers from two hospitals in Mexico (Merida and Monterrey) filled in the S-WISQOL and the Short Form 36 (SF36). Convergent validity was assessed by the correlation of both questionnaires. Internal consistency was evaluated by Cronbach's α, and external validity by comparing between centers. The impact of clinical settings on patients' health-related quality of life (HRQOL) scores was tested. Each hospital's institutional review board approved the project and informed consent was obtained from all participants. A total of 87 Spanish-speakers patients completed the S-WISQOL and SF36 and a good correlation was found between both (r = 0.75, p < 0.001). S-WISQOL readability was rated as "easy". Patients from Merida had longer median duration (years) with stones, more stone-related procedures, and hospitalizations, and scored lower on WISQOL (p = 0.006). Internal consistency was good as Cronbach's α coefficients ranged between acceptable and excellent. Stone-related admissions and duration of stones were inversely correlated with S-WISQOL score (- 0.254 and - 0.283, respectively; p < 0.005) but not to SF36. The S-WISQOL is an internally consistent, reliable, and valid instrument to assess HRQOL in Spanish-speaking patients with kidney stones. The S-WISQOL is generalizable as demonstrated by good external validity among centers. S-WISQOL scores can be added as an outcome for kidney stone treatments.

BACKGROUND: Persistent prostate-specific antigen (PSA) represents a poor prognostic factor for recurrence after radical prostatectomy (RP). OBJECTIVE: To investigate the impact of persistent PSA at 6wk after RP on long-term oncologic outcomes and to assess patient characteristics associated with persistent PSA. DESIGN, SETTING, AND PARTICIPANTS: Within a high-volume center database we identified patients who harbored persistent (≥0.1ng/ml) versus undetectable PSA (<0.1ng/ml) at 6wk after RP. Patients with neo- and/or adjuvant androgen-deprivation therapy (ADT) were excluded. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Logistic regression models tested for prediction of persistent PSA. Kaplan-Meier analyses and Cox regression models tested the effect of persistent PSA on metastasis-free survival (MFS), overall survival (OS), and cancer-specific survival (CSS) rates. Propensity score matching (PSM) was performed to test the impact of salvage radiotherapy (SRT) on OS and CSS in patients with persistent PSA. RESULTS AND LIMITATIONS: Of 11 604 identified patients, 8.8% (n=1025) harbored persistent PSA. At 15yr after RP, MFS, OS, and CSS were 53.0% versus 93.2% (p<0.001), 64.7% versus 81.2% (p<0.001), and 75.5% versus 96.2% (p<0.001) for persistent versus undetectable PSA, respectively. In multivariable Cox regression models, persistent PSA represented an independent predictor for metastasis (hazard ratio [HR]: 3.59, p<0.001), death (HR: 1.86, p<0.001), and cancer-specific death (HR: 3.15, p<0.001). SRT was associated with improved OS (HR: 0.37, p=0.02) and CSS (HR: 0.12, p<0.01) after 1:1 PSM. Main limitation is missing data on postoperative PSA and duration of salvage ADT. CONCLUSIONS: Persistent PSA is associated with worse oncologic outcome after RP, namely, metastasis, death, and cancer-specific death. In patients with persistent PSA, SRT resulted in improved OS and CSS. PATIENT SUMMARY: We assessed the impact of persistent prostate-specific antigen (PSA) at 6wk after radical prostatectomy on oncologic outcomes. Early persistent PSA was associated with worse metastasis-free survival, overall survival, and cancer-specific survival. Salvage radiotherapy may result in a survival benefit in well-selected patients.

OBJECTIVES: To address whether Indocyanine Green (ICG) enhanced fluorescence optical imaging (FOI) is more sensitive than magnetic resonance imaging (MRI) in the detection of synovitis of the wrist and finger joints in rheumatoid arthritis and to analyze the performance of FOI depending on the grade of synovitis. METHODS: Twenty patients with highly active rheumatoid arthritis (mean DAS28-ESR 5.25±1.0) and thirteen healthy volunteers underwent clinical examination, FOI and contrast-enhanced 3T-MRI. Joints were rated by three independent readers semiquantitatively (grade 0-3: no, low, moderate and high grade synovitis) and compared to a semiquantitative composite standard of reference (cSOR, grade 0-3) that incorporated clinical parameters, FOI and MRI results. RESULTS: 2.868 evaluations in 956 joints were performed. FOI had an overall sensitivity of 57.3% and a specificity of 92.1%, whereas MRI had a sensitivity of 89.2% and a specificity of 92.6%. The sensitivity of FOI increased with the degree of synovitis to 65.0% for moderate and severe synovitis (specificity 88.1%) and 76,3% for severe synovitis (specificity 80.5%). The performance of FOI decreased with the degree of synovitis with false negative results predominantly for mild (156/343, 45.5%) and moderate (160/343, 46.6%) synovitis and false positive FOI evaluations predominantly based on weak (grade 1) signals (133/163, 81,6%). CONCLUSION: FOI has a lower sensitivity than 3T-MRI in the detection of synovitis of the hand and finger joints. The diagnostic performance of FOI decreases with the degree of synovitis and with the strength of FOI signals.

Condyloma acuminata is caused by the proliferation of squamous epithelial cells in the presence of human papilloma virus (HPV) infection. There are several treatment options available for anogenital warts, however, none have proven to be more efficacious. We present the case of a 3 year-8 months-old male, diagnosed with human immunodeficiency virus (HIV) infection, who presented with multiple warts in the anogenital region. Lesions were treated with imiquimod 5%, electrosurgical resection and interferon α-2b. Combination of electrofulguration and interferon α-2b is an effective treatment option for children with giant condyloma accuminatum although recurrence is expected within a short follow-up period.
