The combination cytology/epichek test in non muscle invasive bladder carcinoma follow-up: Effective tool or useless expence?

ObjectiveTo identify in which cases after cytological diagnosis, the Bladder EpiCheck test could represent an effective tool in non-muscle invasive bladder carcinoma or an useless expence.Materials and methods375 patients diagnosed with non-muscle invasive bladder cancer, 269 with high grade urothelial carcinoma and 106 with carcinoma in situ, were treated and followed for 1 year. The treatment was an intravesical instillation of Bacillus Calmette-Guerin in 305 patients and Mitomycin-C in 70 patients.During the follow-up patients were evaluated by voided urine cytology and white-light cystoscopy, according to the European Association of Urology Guidelines. Bladder EpiCheck test was performed together with cytology in all cases.ResultsAnalyzing Bladder Epicheck results for each category defined by the Paris System for Reporting Urinary Cytology, we found that the Episcore >60 correlates with histological diagnosis of high grade urothelial carcinoma (HGUC) in atypical urothelial cells and Suspicious for High Grade Urothelial Carcinoma (P = 0.0002 Odds Ratio 0.05926 95% Confidence Interval from 0.01127 to 0.3116 and P = 0.0009 Odds Ratio 0.0315595% Confidence Interval from 0.001683 to 0.5914, Fisher's exact test, respectively), while in Negative for high grade urothelial carcinoma and HGUC patients Episcore is not helpful to identify cases with histological diagnosis of HGUC (P = 0.101 and P = 0.58 Fisher's exact test, respectively). Considering an Episcore ≥ 90 in the HGUC cytological group, this seems not to be correlated with a histological diagnosis of HGUC (P = 0.090 Fisher's exact test).ConclusionsCytology and Bladder EpiCheck test in combination may have the potential to reduce cystoscopies in the follow-up of non-muscle invasive bladder cancer only for cytological diagnoses of atypical urothelial cells and Suspicious for High Grade Urothelial Carcinoma . Moreover, in patients with a cytological diagnosis of Negative for high grade urothelial carcinoma or HGUC, cytology alone seems to be safe and cost-effective.     

Range of motion of foot joints following total ankle replacement and subtalar fusion

BackgroundIn severe cases of ankle and subtalar arthritis, arthrodesis of the subtalar joint is performed in combination with ankle arthroplasty. In these special cases gait analysis reveals real motion at the replaced tibiotalar joint.MethodsTwenty-three patients affected by ankle and subtalar arthritis, treated either with a 3-component or a 2-component prosthesis in combination with subtalar arthrodesis, were clinically evaluated preoperatively and at a minimum of 1-year follow-up. Gait analysis was performed postoperatively using a multi-segment foot protocol. Foot kinematics were compared to corresponding data from a healthy control group.ResultsClinical scores significantly improved from preoperative to follow-up. The clinically measured passive ankle dorsiflexion/plantarflexion significantly improved at the follow-up. Patients’ normalized walking speed and stride length were significantly lower than those in control. With exception of the ankle frontal-plane motion, sagittal-plane mobility of foot joints was about 50% than that in healthy joints.ConclusionsImprovement in clinical scores was found for both prostheses. Normal spatio-temporal parameters were not restored. In these patients, fusion of the subtalar joint appeared to be compensated by larger frontal-plane motion at the tibiotalar joint.Level of evidenceLevel III- retrospective comparative study.The study was approved by the local Ethics Committee as protocol MAT (protocol registration at clinicaltrials.gov NCT03356951).     

Public health challenges and opportunities after COVID-19

With hindsight, the main weakness behind the ineffective response to the coronavirus disease 2019 (COVID-19) pandemic in some countries has been the failure to understand, and take account of, the multilayered systemic interdependencies that spread the effects of the pandemic across social, technological, economic and health-care dimensions. For example, to respond to the COVID-19 pandemic, all people were required to rapidly adjust to social distancing and travel restrictions. Such a complex behavioural response entails adaptation to achieve a full recovery from the systemic shock. To capitalize on the positive effects of disruption to the status quo, much more complex socioeconomic modelling needs to be considered when designing and evaluating possible public health interventions that have major behavioural implications. We provide a simple example of how this reasoning may highlight generally unacknowledged connections and interdependencies and guide the construction of scenarios that can inform policy decisions to enhance the resilience of society and tackle existing societal challenges.     

Gaps in coverage and access in the European Union

This study identifies gaps in universal health coverage in the European Union, using a questionnaire sent to the Health Systems and Policy Monitor network of the European Observatory on Health Systems and Policies. The questionnaire was based on a conceptual framework with four access dimensions: population coverage, service coverage, cost coverage, and service access. With respect to population coverage, groups often excluded from statutory coverage include asylum seekers and irregular residents. Some countries exclude certain social-professional groups (e.g. civil servants) from statutory coverage but cover these groups under alternative schemes. In terms of service coverage, excluded or restricted services include optical treatments, dental care, physiotherapy, reproductive health services, and psychotherapy. Early access to new and expensive pharmaceuticals is a concern, especially for rare diseases and cancers. As to cost coverage, some countries introduced protective measures for vulnerable patients in the form of exemptions or ceilings from user chargers, especially for deprived groups or patients with accumulation of out-of-pocket spending. For service access, common issues are low perceived quality and long waiting times, which are exacerbated for rural residents who also face barriers from physical distance. Some groups may lack physical or mental ability to properly formulate their request for care. Currently, available indicators fail to capture the underlying causes of gaps in coverage and access.     

Destructive spondyloarthropathy and radiographic follow-up in hemodialysis patients

Nine patients undergoing regular dialytic treatment for more than 60 months showed clinical and radiologic features of a noninfective and destructive spondyloarthropathy. The cervical spine was most affected (100%), followed by the dorsal (three patients, 33.3%) and the lumbar spine (two patients, 22.2%). Typically, radiographs and CT scans revealed narrowing of intervertebral spaces, with destruction or sclerosis of the subchondral bone of the vertebral plate.Autopsy was performed on three patients; histologic study demonstrated the presence of large amyloid deposits containing ₂-microglobulin ( ₂-m) in the discs and peridiscal ligaments.A radiographic follow-up of the cervical spine was performed in seven patients after a period of 12 months and showed that the bone destruction in DSA is very rapid and progressive. The lower biocompatibility of the cuprophan membranes of dialyzers is probably the factor most responsible for hyperproduction of ₂-m and subsequently osteoarticular deposition of a new type of amyloidosis.     

Thyroid carcinoma mimicking a toxic adenoma

A young woman with a thyroid papillary carcinoma behaving as an autonomously hyperfunctioning nodule is described. Only 17 similar patients have been seen in the past 25 years. It is emphasized that hyperthyroidism does not exclude malignant disease in hot nodules. This possibility suggests that all thyroid nodules, either cold or hot, require careful management. Therefore, in at risk cases, surgery could be the most useful treatment.     

Non-traumatic brain abscess

Between 1953 and 1989 eighty cases of non-traumatic brain abscess were treated in our department. We have re-examined the clinical and neuroradiological features of this pathological process and present our therapeutic approach and results. We believe that the optimal treatment for brain abscess consists of surgical removal.The prognosis for these lesions has undergone a marked improvement over the last two decades in response to neuroradiological, microbiological and surgical advances. The most influential prognostic factor seems to be preoperative clinical status.     

Involvement of cholecystokinin receptors in the control of striatal dopamine autoreceptors

Summary The interaction of locally perfused cholecystokinin-8 (sulphated) with systemically administered apomorphine was studied on the release of dopamine and its metabolites using microdialysis in the neostriatum of the halothane-anaesthetized male rat. Dialysate levels of dopamine, 3,4-dihydroxyphenylacetic acid and homovanillic acid were assayed by high performance liquid chromatography in combination with electrochemical detection. Perfusion with cholecystokinin-8 (100 M but not 1 M or 10 nM) increased the dialysate levels of dopamine without affecting those of DOPAC or HVA. At low concentrations (1 M and 10 nM but not 1 nM), cholecystokinin-8 counteracted the inhibitory effect of apomorphine (0.05 mg/kg, s. c.) on dopamine release. This counteraction was antagonized by perfusion with the cholecystokinin-8 antagonist proglumide (3 M). At this concentration, proglumide perfused alone was without effect on basal or apomorphine-reduced levels of dopamine. The results indicate a facilitatory effect of cholecystokinin-8 on dopamine release in rat neostriatum only at high concentrations. At lower concentrations, cholecystokinin-8 appears to modulate dopamine release by an inhibitory effect on dopamine autoreceptors possibly involving an intramembrane interaction between presynaptic cholecystokinin-8 receptors and dopamine autoreceptors.
