Dystonia in children with acquired brain injury.

AIM: To quantify the proportion of children who develop dystonia after acquired brain injury (ABI) admitted to a tertiary paediatric intensive care unit (PICU) and analyse the trajectory of dystonia over a 6 month period. METHODS: Children's Health Ireland at Temple Street PICU electronic database was searched for key terms related to ABI from January 1, 2016 to March 14, 2021. Individuals meeting inclusion criteria were analysed, and clinical data pertinent to ABI, dystonia, treatment and outcomes were reviewed. RESULTS: Six-hundred and forty-three PICU episodes (580 patients) met search criteria for ABI, with 379 included in the final analysis. Twelve patients developed dystonia following ABI, giving an incidence of 3.2%. The incidence was higher in the hypoxia/anoxia and TBI cohort at 8.3% and 6.2%, respectively. All patients developed dystonia within the first month following ABI (50% by a week). Patients who developed dystonia compared to non-dystonia cohort had a median lower GCS on admission (4.5 versus 7.0, p value 0.032), longer median length of PICU stay (14.0 versus 3.0 days, p value < 0.001) and were older (median age 9.08 versus 4.68 years, p value 0.06). Dystonia persisted in the majority at 6 months (10/11), requiring on-going medical therapies. CONCLUSION: In our retrospective study, the estimated incidence of dystonia following ABI admitted to the PICU was 3.2%, highest in the hypoxia/anoxia (8.3%) and TBI (6.2%) cohorts. Dystonia emerged early and persisted at 6 months in the majority. This is the first review of dystonia, clinical trajectory and outcomes conducted post-PICU admission for ABI. Future prospective studies are required to determine the true prevalence and burden of disease in the PICU setting.

Requirements for Rehabilitation Services for Children after Severe Acquired Brain Injury.

Aim Acquired brain injury (ABI) is a common cause of acquired disability in children. Rehabilitation services are known to be underdeveloped in Ireland. We aimed to estimate the incidence of severe ABI in young people in Ireland. Methods The National Quality Assurance and Information System (NQAIS) database was analysed to identify patients aged 1-16 years who had suffered a "probable severe acquired brain injury requiring rehabilitation" (PSABIR) from 2016 - 2019. PSABIR is defined as the co-occurrence of a medical condition likely to cause ABI with a length of hospital admission longer than 28 days. Results 187 young people in Ireland had PSABIRs from 2016-2019, accounting for 21.4% of all prolonged admissions (incidence 4.55 per 100,000 per year). Median length of stay was 46 days (IQR 35- 80 days). Two children (1%) were discharged directly to specialist rehabilitation; 132 (70.6%) were discharged directly home. Conclusion Severe ABI accounts for a significant proportion of prolonged paediatric admissions, with an average of 47 such events per year. Most young people spend the acute and subacute phases of recovery in a tertiary acute hospital, before being discharged directly home. Rehabilitation services need to be developed in all settings to address unmet need.

Older age and comorbidity are independent mortality predictors in a large cohort of 1305 COVID-19 patients in Michigan, United States.

INTRODUCTION: Higher comorbidity and older age have been reported as correlates of poor outcomes in COVID-19 patients worldwide; however, US data are scarce. We evaluated mortality predictors of COVID-19 in a large cohort of hospitalized patients in the United States. DESIGN: Retrospective, multicenter cohort of inpatients diagnosed with COVID-19 by RT-PCR from 1 March to 17 April 2020 was performed, and outcome data evaluated from 1 March to 17 April 2020. Measures included demographics, comorbidities, clinical presentation, laboratory values and imaging on admission. Primary outcome was mortality. Secondary outcomes included length of stay, time to death and development of acute kidney injury in the first 48-h. RESULTS: The 1305 patients were hospitalized during the evaluation period. Mean age was 61.0 ± 16.3, 53.8% were male and 66.1% African American. Mean BMI was 33.2 ± 8.8 kg m-2 . Median Charlson Comorbidity Index (CCI) was 2 (1-4), and 72.6% of patients had at least one comorbidity, with hypertension (56.2%) and diabetes mellitus (30.1%) being the most prevalent. ACE-I/ARB use and NSAIDs use were widely prevalent (43.3% and 35.7%, respectively). Mortality occurred in 200 (15.3%) of patients with median time of 10 (6-14) days. Age > 60 (aOR: 1.93, 95% CI: 1.26-2.94) and CCI > 3 (aOR: 2.71, 95% CI: 1.85-3.97) were independently associated with mortality by multivariate analyses. NSAIDs and ACE-I/ARB use had no significant effects on renal failure in the first 48 h. CONCLUSION: Advanced age and an increasing number of comorbidities are independent predictors of in-hospital mortality for COVID-19 patients. NSAIDs and ACE-I/ARB use prior to admission is not associated with renal failure or increased mortality.

Association between Smoking Exposure, Neoadjuvant Chemotherapy Response and Survival Outcomes following Radical Cystectomy: Systematic Review and Meta-Analysis.

PURPOSE: Studies exploring the association of cigarette smoking and long-term survival outcomes following radical cystectomy have yielded mixed results. We performed a systematic review and meta-analysis to investigate the impact of tobacco smoking exposure, duration, intensity and cessation on response to neoadjuvant chemotherapy and long-term survival outcomes in patients undergoing radical cystectomy for bladder cancer. MATERIALS AND METHODS: We systematically searched PubMed®, MEDLINE®, Embase® and Cochrane® Library databases for original articles published before April 2019. Primary end points were neoadjuvant chemotherapy response, overall and cancer specific mortality, and recurrence-free survival after radical cystectomy. Observational studies reporting Cox proportional hazards regression or logistic regression analysis were independently screened. Available multivariable hazard ratios and corresponding 95% CIs were included in the quantitative analysis. Sensitivity analyses were performed as appropriate. A risk of bias assessment was completed for nonrandomized studies. RESULTS: Our electronic search identified a total of 649 articles. After a detailed review we selected 17 studies that addressed the impact of smoking status on survival outcomes in 13,777 patients after radical cystectomy for bladder cancer. Pooled meta-analysis revealed that active smokers have an increased risk of overall mortality (HR 1.21, 95% CI 1.08-1.36; p=0.001, I2=0%), cancer specific mortality (HR 1.24, 95% CI 1.13-1.36; p <0.00001, I2=0%) and bladder cancer recurrence (HR 1.24, 95% CI 1.12-1.38; p <0.0001, I2=3%). Sensitivity analyses evaluating only patients who underwent neoadjuvant chemotherapy followed by radical cystectomy showed an advantage of non/never smokers in terms of neoadjuvant chemotherapy complete response rate (HR 0.47, 95% CI 0.29-0.75; p=0.001, I2=0%). CONCLUSIONS: Smoking status is associated with lower neoadjuvant chemotherapy response rates and higher overall and cancer specific mortality as well as bladder cancer recurrence after radical cystectomy. Appropriate preoperative counseling, together with tightened followup, may have a pivotal role in improving the smoking-related long-term survival outcomes in patients with bladder cancer.

Robotic-assisted laparoscopic repair of rectovesical fistula after Hartmann's reversal procedure.

The case is of a 59-year-old male with history of severe ischemic colitis following emergent intervention for a ruptured infrarenal aortic aneurysm who subsequently underwent left hemicolectomy, partial proctectomy, and Hartmann colostomy. The patient later underwent reversal of the Hartmann colostomy with diverting ileostomy. The surgery was complicated by a right ureteral and posterior bladder injury that resulted in a large rectovesical fistula involving the right hemitrigone and right ureteral orifice. An attempt to repair the rectovesical fistula at an outside facility was unsuccessful. Then, he underwent a robotic-assisted laparoscopic repair of rectovesical fistula, including simple prostatectomy, excision of rectovesical fistulous tract, rectal closure, peritoneal and omental flap interposition, bladder neck reconstruction, vesicourethral anastomosis and right ureteral reimplantation. There were no intraoperative or postoperative complications, and the patient was discharged at postoperative day 4; cystoscopy at 6-week follow-up demonstrated a successful closure of the fistula, at which time the ureteral stents were removed.

Hepatotoxicosis in cattle associated with consumption of Punica granatum (pomegranate).

CASE REPORT: Ingestion of pomegranates was associated with the deaths of 9 of 35 young cattle; 8 were found dead without any prior clinical signs being noted and 1 animal was observed to be weak with pale-pink mucous membranes. Gross pathological changes included widespread subcutaneous and serosal haemorrhages and the liver showed an enhanced acinar or 'nutmeg-like' pattern. The significant histopathological lesion was severe, acute periacinar to midzonal hepatocellular necrosis. These findings were considered characteristic of a hepatotoxicosis; however, other than the possible involvement of pomegranates, no known hepatotoxins were detected in the pasture or water sources. CONCLUSION: Consumption of large quantities of whole pomegranates is capable of causing severe hepatic necrosis resulting in the death of cattle. At this stage it is unknown whether the toxic principle is within the pomegranates or produced by a microbe associated with the deteriorating fruit.

Robotic uterine-sparing vesicovaginal fistula repair.

INTRODUCTION AND HYPOTHESIS: The objective was to describe a technique for the robotic repair of complex vesicovaginal fistula (VVF) with uterine preservation. METHODS: From 2015 to 2017, two patients underwent the procedure. Following placement of the patient in the lithotomy position, catheterization of the fistulous tract and laparoscopic omental harvesting is performed. Then, the robotic system is docked. A transverse incision was made in the peritoneum above the uterus was made to provide access to the bladder, the uterus is mobilized, and a cystotomy is performed to identify the structures. Subsequently, the cystotomy is extended toward the fistulous tract, the plane between the organs is dissected to proceed with the vaginal closure, the vagina is closed, the omental flap is interposed, and the bladder is closed. RESULTS: Mean operative time (OT) was 219 min. Mean estimated blood loss (EBL) was 75 ml. One of the patients had an intraoperative cervix canal injury that was identified and repaired. The postoperative course was uneventful, and the mean length of hospital stay (LOS) was 1 day. A mean follow-up of 17 (±9.89) months showed no recurrence at cystoscopy or imaging evaluation. CONCLUSIONS: Uterine-sparing VVF repair is feasible and safe. More studies are needed to assess equivalence compared with other procedures.

Overall survival and oncological outcomes after partial nephrectomy and radical nephrectomy for cT2a renal tumors: A collaborative international study from the French kidney cancer research network UroCCR.

BACKGROUND: Partial nephrectomy (PN) is recommended as first-line treatment for cT1 stage kidney tumors because of a better renal function and probably a better overall survival than radical nephrectomy (RN). For larger tumors, PN has a controversial position due to lack of evidence showing good cancer control. The aim of this study was to compare the results of PN and RN in cT2a stage on overall survival and oncological results. METHOD: A retrospective international multicenter study was conducted in the frame of the French kidney cancer research network (UroCCR). We considered all patients aged≥18 years who underwent surgical treatment for localized renal cell carcinoma (RCC) stage cT2a (7.1-10cm) between 2000 and 2014. Cox and Fine-Gray models were performed to analyze overall survival (OS), cancer specific survival (CSS) and cancer-free survival (CFS). Comparison between PN and RN was realized after an adjustment by propensity score considering predefined confounding factors: age, sex, tumor size, pT stage of the TNM classification, histological type, ISUP grade, ASA score. RESULTS: A total of 267 patients were included. OS at 3 and 5 years was 93.6% and 78.7% after PN and 88.0% and 76.2% after RN, respectively. CSS at 3 and 5 years was 95.4% and 80.2% after PN and 91.0% and 85.0% after RN. No significant difference between groups was found after propensity score adjustment for OS (HR 0.87, 95% CI: 0.37-2.05, P=0.75), CSS (HR 0.52, 95% CI: 0.18-1.54, P=0.24) and CFS (HR 1.02, 95% CI: 0.50-2.09, P=0.96). CONCLUSION: PN seems equivalent to RN for OS, CSS and CFS in cT2a stage kidney tumors. The risk of recurrence is probably more related to prognostic factors than the surgical technique. The decision to perform a PN should depend on technical feasibility rather than tumor size, both to imperative and elective situation. LEVEL OF EVIDENCE: 4.

Live surgery: highly educational or harmful?

PURPOSE: Live surgery (LS) is considered a useful teaching opportunity. The benefits must be balanced with patient safety concerns. To evaluate the rate of complications of a series of urologic LS performed by experts during the Congress Challenge in Laparoscopy and Robotics (CILR). METHODS: We present a large, multi-institution, multi-surgeon database that derives from 12 CILR events, from 2004 to 2015 with a total of 224 cases. Radical prostatectomy (RP) was the most common procedure and a selection of complex cases was noted. The primary measure was postoperative complications and use of a Postoperative Morbidity Index (PMI) to allow quantitative weighing of postoperative complications. RESULTS: From 12 events, the number of cases increased from 11 in 2004 to 27 in 2015 and a total of 27 surgeons. Of 224 cases (164 laparoscopic and 60 robotic), there were 26 (11.6%) complications: 5 grade I, 5 grade II, 3 grade IIIa, 12 grade IIIb and 1 grade V, the latter from laparoscopic cystectomy. Analysis of PMI was 23 times higher from cystectomy compared to RP. CONCLUSIONS: In the setting of live surgery, the overall rate of complications is low considering the complexity of surgeries. The PMI is not higher in more complex procedures, whereas RP seems very safe.

Ultrasonographic characteristics of accessory sex glands and spectral Doppler indices of the internal iliac arteries in peri- and post-pubertal Dorper rams raised in a subtropical climate.

The aim of the present study was to determine and compare ultrasonographic characteristics of accessory sex glands and spectral Doppler indices of the internal iliac arteries in peri- and post-pubertal rams raised in a subtropical climate. Forty-five Dorper rams were examined (24 rams aged 8-11 months and 21 rams aged 12-24 months). Digital images of all accessory sex glands were subjected to morphometric and echotextural analyses, the latter using commercially available image analytical software Image ProPlus®. Physical and morphological characteristics of semen and serum concentrations of testosterone were also determined. The dimensions of the prostate gland (12.9±1.2 compared with 14.2±2.7mm; mean±standard deviation) and bulbourethral glands (13.7±1.3 compared with 14.7±1.8mm) were greater (P=0.04) in sexually mature compared with peri-pubertal rams. Pixel intensity of vesicular (181.5±20.8 compared with 164.8±26.8, P=0.02) and bulbourethral gland parenchyma (166.9±16.9 compared with 141.8±29.1, P=0.001) was greater in peri-pubertal compared with sexually mature rams. Semen could be collected by ejaculation into the artificial vagina from 38% (8/21) of post-pubertal rams and 21% (5/24) of peri-pubertal animals (P=0.03). Semen volume was positively correlated with peak systolic velocity (PSV) and end-diastolic velocity (EDV) in the internal iliac arteries (r=0.79, P=0.001 and r=0.67, P=0.01, respectively), while spermatic vigor and progressive motility were inversely related to circulating concentrations of testosterone (r=-0.69, P=0.009 and r=-0.61, P=0.03, respectively). In summary, the attainment of sexual maturity in the rams of the present study was associated with an enlargement of the prostate and bulbourethral glands, and with the shift in echotextural attributes of vesicular and bulbourethral glands. Circulating testosterone concentrations and Doppler blood flow indices of the ram's internal iliac arteries are significant predictors of sperm progressive motility, vigor and the amount of ejaculate.

Out of sight, out of mind? A national survey of paediatricians in Ireland regarding Fetal Alcohol Spectrum Disorders.

Fetal Alcohol Spectrum Disorders (FASDs) are one of the major causes of preventable developmental delay. There is no register of children with FASDs in Ireland. Up to 81% of Irish women report drinking alcohol during the periconceptual period or pregnancy. We aimed to evaluate self-reported knowledge and practice of doctors working in paediatrics in Ireland with regards to FASDs and alcohol consumption during pregnancy. We circulated a survey to all paediatric doctors in Ireland, either enrolled in specialist training or registered as trainers. Fifty-six respondents (31.3%) were unaware of the existence of FASDs. Sixty-two (34.6%) believed most patients with FASDs have dysmorphic features. Seventy-three respondents (40.8%) routinely ask about maternal alcohol consumption during pregnancy in the context of developmental delay. Thirty-one respondents (17.3%) stated that mild alcohol intake in the third trimester of pregnancy is safe. Our survey suggests prenatal alcohol exposure may not be routinely considered in the evaluation of children with developmental delay by paediatric doctors in Ireland.

[Interest using 3D ultrasound and MRI fusion biopsy for prostate cancer detection]. / Quel est l'intérêt de l'échographie 3D et fusion d'image IRM pour la détection du cancer de la prostate ?

INTRODUCTION: The strategic therapy for prostate cancer depends on histo-pronostics data, which could be upgraded by obtaining targeted biopsies (TB) with MRI (magnetic resonance imagery) fusion 3D ultrasound. OBJECTIVES: To compare diagnostic yield of image fusion guided prostate biopsy using image fusion of multi-parametric MRI (mpMRI) with 3D-TRUS. MATERIALS AND METHODS: Between January 2010 and April 2013, 179 consecutive patients underwent outpatient TRUS biopsy using the real-time 3D TRUS tracking system (Urostation™). These patients underwent MRI-TRUS fusion targeted biopsies (TB) with 3D volume data of the MRI elastically fused with 3D TRUS at the time of biopsy. RESULTS: A hundred and seventy-three patients had TBs with fusion. Mean biopsy core per patient were 11.1 (6-14) for SB and 2.4 (1-6) for TB. SBs were positive in 11% compared to 56% for TB (P<0.001). TB outperformed systematic biopsy(SB) in overall any cancer detection rate, detection of clinically significant cancer (58% vs. 36%), cancer core length (6.8mm vs. 2.8mm), and cancer rate per core (P<0.001). In multivariable logistic regression, with TB we have more chance to find a clinically significant cancer (OR:3.72 [2-6.95]). When both TRUS and MRI are positive, there is 2.73 more chance to find a clinically significant cancer. CONCLUSION: MR/TRUS elastic fusion-guided biopsies outperform systematic random biopsies in diagnosing clinically significant cancer. Ability of interpretation of real-time TRUS is essential to perform the higher level of MR/US fusion and should be use for active surveillance. LEVEL OF PROOF: 4.

An oral lesion as the primary clinical manifestation of sarcoidosis.

An oral lesion as the first clinical presentation of sarcoidosis is extremely rare. We present the case of a 39-year-old woman who was referred to the oral and maxillofacial surgery department with a persistent asymptomatic nodular lesion in the hard palate. This was located adjacent to a grossly carious upper first molar and a provisional diagnosis of chronic periapical granuloma was made. An incisional biopsy of the lesion was carried out, which unexpectedly revealed the presence of a non-caseating granulomatous inflammatory reaction. A referral was sent to the respiratory medicine team and a diagnosis was later confirmed of stage II sarcoidosis. This case report highlights the need for clinicians to be aware of all possible causes of oral lesions, including rare manifestations of underlying systemic disease.

Standardization of definitions in focal therapy of prostate cancer: report from a Delphi consensus project.

PURPOSE: To reach standardized terminology in focal therapy (FT) for prostate cancer (PCa). METHODS: A four-stage modified Delphi consensus project was undertaken among a panel of international experts in the field of FT for PCa. Data on terminology in FT was collected from the panel by three rounds of online questionnaires. During a face-to-face meeting on June 21, 2015, attended by 38 experts, all data from the online rounds were reviewed and recommendations for definitions were formulated. RESULTS: Consensus was attained on 23 of 27 topics; Targeted FT was defined as a lesion-based treatment strategy, treating all identified significant cancer foci; FT was generically defined as an anatomy-based (zonal) treatment strategy. Treatment failure due to the ablative energy inadequately destroying treated tissue is defined as ablation failure. In targeting failure the energy is not adequately applied to the tumor spatially and selection failure occurs when a patient was wrongfully selected for FT. No definition of biochemical recurrence can be recommended based on the current data. Important definitions for outcome measures are potency (minimum IIEF-5 score of 21), incontinence (new need for pads or leakage) and deterioration in urinary function (increase in IPSS >5 points). No agreement on the best quality of life tool was established, but UCLA-EPIC and EORTC-QLQ-30 were most commonly supported by the experts. A complete overview of statements is presented in the text. CONCLUSION: Focal therapy is an emerging field of PCa therapeutics. Standardization of definitions helps to create comparable research results and facilitate clear communication in clinical practice.
