ABSTRACT

INTRODUCTION: The use of a temporaryor permanent catheter is very common in clinical practice. Between 15.0% and 25.0% of hospitalized patients have in-dwelling bladder catheters, the majority of which are short-term. Bladder catheter clamping before catheter removal was generally regarded as useful in the past. Today, its utility is questionable.

OBJECTIVE: To determine the association between bladder catheter clamping and spontaneous micturition or acute urinary retention (AUR) in postoperative patients with short-term indwelling bladder catheter.

MATERIALS AND METHODS: A descriptive, comparative,longitudinal study was conducted at a secondary care hospital center in a western Mexican state .AUR was the outcome variable. Two study groups wereformed: patients with bladder catheter clamping (n=43) and the control patients with no bladder catheter clamping (n=41). Descriptive statistical analyses were performed, and percentage comparisons were made with the chi-squaretest. Significant predictors were subsequently added to the multivariate model.

RESULTS: Fourteen percent (n=12) of all the study patients, with and without bladder catheter clamping, presented with AUR and 86% (n=72) did not. In the association analysis, there was no statistically significant difference between presenting with AUR and having or not having bladder catheter clamping (p=0.59). The associations of AUR with bladder re-catheterization (p=0.001), age (p=0.01), and the presence of lower urinary symptoms (p= 0.005) were statistically significant.

CONCLUSION: Postoperative bladder catheter clamping was not associated with the presence of AUR.

ABSTRACT

INTRODUCTION AND OBJECTIVES: Multiple chemical sensitivity (MCS) is a multi-symptomatic systemic disease whose genitourinary symptoms are poorly known. The aim of this article is to study these symptoms in Spanish publications. MATERIALS AND METHODS: A retrospective study of descriptive type on the genitourinary symptoms of MCS is carried out in the Spanish publications between the years 2000 and 2019. The search in Medline was performed with MeSH terms “multiple chemical sensitivity Spanish” and in Google with free terms “sensibilidad química multiple España”. In the publications found, only those referring to genitourinary symptoms were selected, in which year, authors, type of article (clinical case, review, casuistry), genital symptoms, urinary symptoms, specialty, hospital or centre and city were studied. The results of these variables have been analyzed with descriptive statistics.

RESULTS: We found 45 Spanish publications on MCS of which 20 (44,4%) mentioned genitourinary symptoms. The 20 articles corresponded to 7 clinical cases, 6 reviews, 2 case series, 2 updates, 1 book chapter, 1 special article and 1 consensus document. We found 12 publications on female genital symptoms (60%), 12 on urinary symptoms (60%) and 4 on male genital symptoms (20%). The specialties with the highest number of publications were Family Medicine and Psychiatry with 3 (15%) and Neumology, Toxicology and Anesthesia and Resuscitation with 2 (10%). There are publications from 13 hospitals and 7 national centers, health agencies or foundations. The publications corresponded to 10 cities, the 2 with the most publications being Madrid with 6 (30%) and Barcelona with 6 (30%). CONCLUSIONS: The genitourinary symptoms of MCS are mentioned in about half of the Spanish publications. There is a clear predominance of these symptoms in women. This “genitourinary syndrome” should be taken into account in urological and gynecological patients with MCS.

ABSTRACT

OBJECTIVE: To compare systematic biopsy with MRI-TRUS fusion prostate biopsy in terms of cancer detection rates.

PATIENTS AND METHODS: The data of the patients who had a Prostate Imaging Reporting and Data System (PI-RADS) score of 3 or more lesions on mpMRI and underwent MRI-TRUS fusion biopsy with simultaneous 12-core standard systematic biopsy from June 2016 to June 2019 in our tertiary center were retrospectively reviewed. Clinical, radiological and pathological data were recorded. Statistical difference among the groups was determined by using McNemar tests.

RESULTS: A total of 344 patients were included in the study. As a result of transrectal targeted and systematic combined biopsy, 117 patients were diagnosed with prostate cancer. Benign pathology rates in patients with PI-RADS 3, PI-RADS 4, and PI-RADS 5 lesions were 93.8%, 68.5%, and 46.4%, respectively. Patients were divided into two groups as ISUP grade 1 and ISUP grade ≥2 and cancer detection rates (CDRs) were found significantly higher in transrectal targeted biopsy compared with the systematic biopsy (12.5% vs. %6.4, p=0.007 and 17.4% vs. 8.7%, p<0.001, respectively). Targeted biopsy CDRs were found significantly higher in the high PSA density group (24.5% vs. 41.4%, p=0.001) unlike the systematic biopsy.

CONCLUSION: Transrectal targeted biopsy was superior to systematic biopsy in the diagnosis of prostate cancer. Clinicians should be more selective when making a biopsy decision for patients with PI-RADS 3 lesions. PSA density can be used as a criterion for patient selection for targeted biopsy.

ABSTRACT

BACKGROUND: Iodinated contrast medium exposure is associated with acute kidney injury (AKI). Patients with severe contrast-induced AKI (CI-AKI) may need renal replacement therapy (RRT). Prediction models exist for CI-AKI, but few need RRT. We aimed to establish a preprocedural score model to stratify patients at risk of unplanned postprocedural RRT following invasive coronary angiography (ICA) or percutaneous coronary intervention (PCI).

METHODS AND RESULTS: Between January 2010 and December 2015, a series of 3,469 patients were randomly divided into two cohorts at a 2 : 1 ratio for model development and validation, respectively. A total of 36 patients (1.0%) needed unplanned postprocedural RRT following ICA and/or PCI. Multivariable logistic regression was used to build the risk model. C-statistic and Hosmer-Lemeshow tests were used to evaluate the performance of the model. Five preprocedural variables – independently associated with unplanned postprocedural RRT – were identified as factors of the risk score model with different scores: age > 75 years (1), serum creatinine level ≥ 1.5 mg/dL (1), diabetes mellitus (1), hypotension (2), and acute myocardial infarction (2). The risk score model was demonstrated with high discrimination (C-statistic = 0.872) and goodness of fit (χ2 = 3.769, p = 0.438). Furthermore, the model allowed a hierarchical classification of low, intermediate, and high risk, within which the observed unplanned RRT rates were ~ 0.4, 3.0, and 20.0%, respectively.

CONCLUSION: Using preprocedural variables, we developed and validated a risk model for unplanned postprocedural RRT following ICA and/or PCI.

ABSTRACT

BACKGROUND: Online neuropsychological assessment batteries may facilitate the screening of cognitive functions in older adults and could be useful for early diagnosis and detection of cognitive impairments.

OBJECTIVE: The primary aim of this study was to assess the psychometric qualities of an online multi-domain cognitive assessment battery (General Cognitive Assessment Battery (GCAB) by Cognifit™) applied for the first time in Bulgaria.

METHODS: A total of 20 healthy older adults (6 male and 14 female, aged 60-82) completed the GCAB as well as the Mini-Mental State Examination (MMSE) and the Consortium to Establish a Registry for Alzheimer’s Disease (CERAD) neuropsychological battery. Descriptive statistics were used to describe the demographic characteristics of the sample and the scores on the GCAB and the CERAD battery. The internal consistency of the GCAB was evaluated using item analysis and measured with Cronbach’s alpha. The concurrent validity of the GCAB was assessed with respect to the CERAD using Spearman’s r after verifying the linear relationship between the GCAB and CERAD scores.

RESULTS: The GCAB showed good concurrent validity when compared with the corresponding CERAD tests. The correlation coefficients ranged from 0.67 for working memory to 0.47 for short-term auditory memory. We found very good reliability of the GCAB, with the inter-class correlation coefficient higher than 0.8 for all cognitive domains. There were no significant correlations between MMSE and GCAB scores.

CONCLUSION: The GCAB was found to be valid for the cognitive screening of Bulgarian healthy older adults and may provide an adequate assessment of their cognitive status. The GCAB showed good concurrent validity when compared with the CERAD battery, measuring similar cognitive constructs. Further work is necessary to explore its validity and reliability.

ABSTRACT

OBJECTIVE: To correlate dual energy computed tomography electron density measurements with histopathological cerebral glioma grading to determine whether it can be used as a non-invasive predictor of cerebral glioma grade.

MATERIALS AND METHODS: Fifty patients with suspected cerebral gliomas on imaging scheduled to undergo resection were included. We tested our hypothesis that with increasing glioma grade, increased tumor cellularity should translate into increased electron density and if a statistically significant difference between electron density of low-grade gliomas and high-grade gliomas is seen, we may have a clinical use of dual energy computed tomography as a non-invasive tool to predict cerebral glioma grade.A pre-operative dual energy computed tomography scan of the brain was performed, and electron density measurements calculated from the solid part of the tumor. Obtaining a ratio with electron density of contralateral normal brain parenchyma normalized these values. The minimum, maximum and mean electron density and their normalized values recorded between high-grade gliomas and low-grade gliomas were compared for presence of statistical significance.

RESULTS: A statistically significant difference was found between all six parameters recorded (minimum electron density and normalized values, mean electron density and normalized values, maximum electron density and normalized values) between low-grade gliomas and high-grade gliomas. The predictivity ranged from 75% (for minimum electron density and maximum normalized values) to 81.25% (for mean normalized values). All six parameters were found to have statistically significant positive correlation with Ki-67 index.

CONCLUSION: Dual energy computed tomography electron density measurements in cerebral gliomas are predictive of pre-operative differentiation of low-grade gliomas from high-grade gliomas and show a linear, statistically significant positive correlation with Ki-67 index.

ABSTRACT

BACKGROUND: This study aimed to compare the masticatory efficiency, the maximum voluntary occlusal bite force (MVOBF) and the electrical activity (EMG) of masticatory muscles of practitioners of upper limb bodybuilding before and after physical activity.

MATERIAL AND METHODS: Twenty healthy individuals (10 men and 10 women, age from 18 to 30 (mean of 24.7 years old) without masticatory system disorders, that regularly practice hypertrophic physical activity were submitted to the analyses of masticatory efficiency, MVOBF, and surface EMG of the temporalis and masseter muscles. The masticatory efficiency was analyzed by comminution of the artificial material (Optocal®) and a sieving method. The MVOBF was measured by a dynamometer, and EMG was evaluated during resting mandibular position, maximum voluntary clenching (MVC), and MVC with a Parafilm M tape between teeth, and free mastication of chewing gum. The analyses were made before (T0) and immediately after the performance of upper limb bodybuilding exercises (T1). The data of masticatory efficiency and MVOBF were submitted to the Student T-test, and their correlations were analyzed by the Pearson correlation test, and the EMG data were submitted to the 2-way repeated measures ANOVA, all tests with a 5% significance.

RESULTS: There was a significant decrease of masticatory efficiency after the training. No statistical difference in the MVOBF and EMG was found, and there was a positive correlation between masticatory efficiency and MVOBF.

CONCLUSIONS: Therefore, changes were found for masticatory efficiency only, which decreased after hypertrophic exercise. There was a positive correlation between masticatory efficiency and MVOBF. Key words:Masticatory efficiency, bite force, physical activity, electromyography.

ABSTRACT

BACKGROUND: This study evaluated the effects of several epoxy resin-based sealer compositions (AHP, AH Plus; ADS, Adseal; SPL, Sealer Plus) on bond strength and intratubular dentin penetration of the endodontic obturation, in root canal previously treated with calcium hydroxide intracanal medication (CH) and removed by continuous ultrasonic irrigation (CUI).

MATERIAL AND METHODS: Forty-five maxillary canines were prepared up to F5 (ProTaper system), filled with CH, coronally sealed, and stored at 37ºC. After 1 week, CH was removed using 2.5% sodium hypochlorite energized by CUI. The specimens were randomly distributed in three groups (n=15) and root canal obturated, according to epoxy-based resin sealer composition (AHP, ADS or SPL). The roots were transversally sectioned in cervical, middle, and apical thirds. In each radicular third, push out bond strength using universal machine and intratubular dentin using confocal laser scanning microscopy (CLSM) and Image J Program were evaluated. Bond strength and intratubular dentin penetration were statistically evaluated by ANOVA one-way and Tukey tests and Kruskal Wallis test, respectively (α = 0.05).

RESULTS: In middle and apical thirds, AHP showed higher bond strength values (p<0.05), and ADS and SPL were similar each other (p>0.05). All epoxy resin-based sealers presented similar intratubular dentin penetration, independently of the radicular thirds (p>0.05). Cohesive and mixed failures were predominant in the cervical thirds. In the middle and apical thirds, AHP showed more cohesive type failures, while ADS and SPL showed more adhesive-type failures.

CONCLUSIONS: AHP has the highest bond strength in middle and apical radicular thirds, after calcium hydroxide intracanal medication removal using continuous ultrasonic irrigation, although intratubular dentin infiltration being similar among epoxy resin-based sealer with several chemical composition. Key words:Continuous ultrasonic irrigation, endodontic sealers, epoxy resin-based sealers, root canal obturation.

ABSTRACT

BACKGROUND: The first state of alarm due to COVID-19 in Spain led to limit dental treatment exclusively to emergencies. The objective of the survey was to evaluate the amount and type of emergencies attended during this period, as well as to know how they were solved, and what measures were adopted to carry out dental care in these exceptional circumstances.

MATERIAL AND METHODS: This cross-sectional study included 312 Spanish dentists, who fulfilled an online questionnaire with 22 closed questions, divided into five sections regarding to various aspects of professional dental profile and emergency care. Descriptive statistic and Chi-square tests were performed (p<0.05).

RESULTS: 75.64% of respondents attended emergencies in person only when required, being dental pain the main emergency (90.38%). Dental emergency care in person involved a prior telephone triage of the patient to identify possible COVID-19 symptoms, as well as protective measures implementation for both, the patient and the dentist, at dental office.

CONCLUSIONS: The number of dental emergencies decreased during the state of alarm, being dental pain the main cause of dental assistance via telephone or in person. Triage of patients before scheduling an in-person appointment and protective measures implementation were common features in dental emergency care during the first state of alarm period. Key words:Dental emergencies, COVID-19, state of alarm, survey.

ABSTRACT

BACKGROUND: Oral care products containing bioactive agents obtained from extracts of plant drugs were launched. This in vitro study investigated the effects of herbal-containing toothpastes associated or not with fluoride to remineralize the enamel after cariogenic challenge with pH cycling. The chemical and physical factors of toothpastes and the enamel surface roughness after brushing were also analyzed.

MATERIAL AND METHODS: Sixty bovine enamel blocks were obtained and divided into 3 thirds: intact (untreated), demineralized (artificial caries lesion), and treated (caries lesion, pH cycling, and brushing with toothpastes). Toothpastes containing herbal compounds contained no fluoride [Galla chinensis (GCH)], low-F concentration [D’Or (DOR); Herbal Bliss (HBL)], or a different fluoride type [Elmex Anticaries (EAC)]. The results were compared to NaF-containing toothpastes: 1450 and 5000 ppm. Enamel blocks were brushed with the toothpastes using a pH-cycling model (7 days). The Knoop hardness (25g/10s) of the surface and the longitudinal sections were then evaluated. The percentage of surface hardness recovery (%SHR) was calculated. The enamel surface roughness, pH, particle size, zeta potential, and polydispersity index of toothpaste slurries were also evaluated. Data were statistically analyzed (α=5%).

RESULTS: No significance was observed when %SHR was compared (p>0.05). DOR, GCH, and HBL were more effective in remineralizing the enamel subsurface. Significantly higher surface roughness was observed when treated with EAC and GCH (p<0.05).

CONCLUSIONS: All toothpastes were able to remineralize the enamel, especially the subsurface, with results equal or better than that of standard toothpastes. Key words:Enamel, hardness, roughness, toothpaste, tooth remineralization.
