RESUMEN

INTRODUCTION: Artificial intelligence (AI) is constantly developing in several medical areas and has become useful to assist with treatment planning. Orthodontics and maxillofacial surgery use AI-based technology to identify and select cephalometric points for diagnostics. Although some studies have shown promising results from the use of AI, the evidence is still limited. Hence, additional investigation is justified. MATERIALS AND METHODS: In this retrospective study, 2 human operators (1 expert and 1 inexperienced) and 1 software analyzed 30 lateral cephalograms of individuals with orthodontic treatment indications. They measured 10 cephalometric variables and then 2 weeks later, repeated measurements on 30% of the sample. We evaluated the reliability of the measurements between the 2-time points and the differences in the means between the expert operator and the AI software and between the expert and inexperienced operators. RESULTS: There was high reliability for the expert operator and AI measurements, and moderate reliability for the inexperienced operator measurements. There were some significant differences in the means produced by the AI software and the inexperienced operator compared with the expert operator. CONCLUSION: Although AI is useful for cephalometric analysis, it should be used with caution because there are differences compared with analysis by humans.

RESUMEN

OBJECTIVE: Orthognathic surgery is a viable and reproducible treatment for facial deformities. Despite the precision of the skeletal planning of surgical procedures, there is little information about the relations between hard and soft tissues in three-dimensional (3D) analysis, resulting in unpredictable soft tissue outcomes. Three-dimensional photography is a viable tool for soft tissue analysis because it is easy to use, has wide availability, low cost, and is harmless. This review aims to establish parameters for acquiring consistent and reproducible 3D facial images. METHODS: A scoping review was conducted across PubMed, SCOPUS, Scientific Electronic Library Online (SciELO), and Web of Science databases, adhering to "Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews" guidelines. Articles presenting 3D facial photographs in the diagnostic phase were considered. RESULTS: A total of 79 articles were identified, of which 29 were selected for analysis. CONCLUSION: The predominant use of automated systems like 3dMD and VECTRA M3 was noted. User positioning has highest agreement among authors. Noteworthy aspects include the importance of proper lighting, facial expression, and dental positioning, with observed discrepancies and inconsistencies among authors. Finally, the authors proposed a 3D image acquisition protocol based on this research findings.

RESUMEN

OBJECTIVE: This study evaluated the protective capacity of a sugarcane-derived cystatin (CaneCPI-5) in different vehicles (1-solution and 2-chitosan gel) against erosive dentin wear in situ. METHODS: In part-1, 15 volunteers participated in a crossover protocol (solutions): Water; Elmex™ and CaneCPI-5. The volunteers wore an appliance with 4 dentin samples for 5 days. These samples were treated with a drop of the solutions for 1 min (4X/d), then the acquired pellicle (AP) was formed and the samples were subjected to erosive challenges (EROSION: citric acid, for 90 s, 4X/day). 2X/day, half of the samples were also abraded for 15 s (ABRASION). In part-2, 16 volunteers participated in a crossover protocol (gel): No gel, Chitosan gel, Chitosan gel + NaF and Chitosan gel + CaneCPI-5. The volunteers also wore an appliance. The samples were treated once/day with the gel or not for 4 min, then the AP was formed and the samples were subjected to erosive and abrasive challenges, as reported in part-1. Dentin wear was measured by profilometry. Data were analyzed by two-way RM-ANOVA and Sidak's tests (p < 0.05). RESULTS: Part-1: Elmex™ and CaneCPI-5 significantly reduced dentin loss in comparison with Water for the EROSION/ABRASION conditions (p < 0.05). Part-2, all the treated groups significantly reduced the dentin loss in comparison to the No gel. The greatest reduction was found for the gel + CaneCPI-5 group for the EROSION/ABRASION (p < 0.05). CONCLUSION: The solution and chitosan gel containing CaneCPI-5 protected against erosive dentin wear in situ. CLINICAL RELEVANCE: These different vehicles are probably sufficient for protecting people with high risk of developing erosive dentin wear.

RESUMEN

Oral mucositis (OM) is a frequent complication in cancer patients who are undergoing chemotherapy or radiotherapy. It manifests as an inflammation of the oral mucosa, sometimes provoking severe consequences such as eating limitations, difficulty in speaking, and possibly superinfection. Aim: The aim of this review was to update the evidence published during the last five years on the treatment of oral mucositis induced by radiotherapy and/or chemotherapy in patients with cancer. Materials and Method: A search was conducted in Pubmed, Scielo and Scopus, using the search terms mucositis, stomatitis, therapy, treatment, oral cancer, oral squamous cell carcinoma, head and neck cancer and head and neck carcinoma, with Mesh terms and free terms, from 2017 to January 2023. The systematic review was conducted in accordance with the PRISMA guidelines. Results: A total 287 articles were retrieved, of which 86 were selected by title and abstract, and 18 were included after full-text analysis. The most frequently assessed variables were OM severity, pain intensity and healing time. Treatment types were diverse, and included drugs, mouthwashes, medicines based on plant extracts, cryotherapy and low-intensity laser therapies. Conclusion: Dentoxol mouthwashes, Plantago major extract, thyme honey extract, zinc oxide paste, vitamin B complex combined with GeneTime, and the consumption of L-glutamine are effective in diminishing the severity of OM. Pain intensity was lower with doxepin mouthwashes and diphenhydramine-lidocaine-antacid mouthwashes.

RESUMEN

The sugarcane cystatin 5 (CaneCPI-5) showed protection against erosion and erosive tooth wear (ETW) under several protocols. However, evaluating these conditions in vivo is hard due to the lack of a suitable device. The aim of this study was to use clinically the relative surface reflection intensity (%SRI) by the Reflectometer Optipen to assess the acquired pellicle engineering with CaneCPI-5 rinse for the prevention of initial erosion in vivo. Nine volunteers were distributed in three cross-over phases, according to the rinse used, as follows: 1) Deionized water (negative control); 2) Elmex® (800 ppm Sn2+, 500 ppm F-; positive control); 3) 0.1 mg/mL CaneCPI-5. The following experimental steps were performed: Initially, the volunteers received prophylaxis and the initial %SRI was performed. Subsequently, they rinsed with the solutions (10 mL; 1min), followed by the formation of the acquired enamel pellicle (AEP; 120min). After, the erosive challenge with citric acid 1%, pH 2.5 (10 µL; 10s) was performed (in isolation) on the buccal surface of the maxillary central incisors (right and left). The calcium present in the acid was analyzed by Arsenazo III method. Finally, the final %SRI was performed. Data were analyzed by Kruskal-Wallis/Dunn's tests and Spearman's correlation were used (p < 0.05). For both variables, the negative control led to significantly less protection (lower reflectivity and higher calcium release) in comparison with the other groups. The best protection (higher reflectivity and lower calcium release) was observed for the Elmex® and the CaneCPI-5 groups, with no significant differences between them (p < 0.05). There was a significant correlation between both analyzes. The Reflectometer Optipen demonstrated to be a good device to assess clinically. Moreover, CaneCPI-5 rinse proved effective through acquired pellicle engineering against initial erosion in vivo.

RESUMEN

Emerging deep learning-based applications in precision medicine include computational histopathological analysis. However, there is a lack of the required training image datasets to generate classification and detection models. This phenomenon occurs mainly due to human factors that make it difficult to obtain well-annotated data. The present study provides a curated public collection of histopathological images (DeepHP) and a convolutional neural network model for diagnosing gastritis. Images from gastric biopsy histopathological exams were used to investigate the performance of the proposed model in detecting gastric mucosa with Helicobacter pylori infection. The DeepHP database comprises 394,926 histopathological images, of which 111 K were labeled as Helicobacter pylori positive and 283 K were Helicobacter pylori negative. We investigated the classification performance of three Convolutional Neural Network architectures. The models were tested and validated with two distinct image sets of 15% (59K patches) chosen randomly. The VGG16 architecture showed the best results with an Area Under the Curve of 0.998%. The results showed that CNN could be used to classify histopathological images from gastric mucosa with marked precision. Our model evidenced high potential and application in the computational pathology field.

RESUMEN

OBJECTIVE: This study evaluated the preventive effect of a chitosan gel containing CaneCPI-5 against enamel erosion and erosion + abrasion in situ. METHODS: Sixteen volunteers participated in a crossover, double-blind protocol, comprising 4 phases: (1) no treatment (Nt); (2) chitosan gel (Cg); (3) chitosan gel + 12,300 ppm NaF (Cg + NaF); and (4) chitosan gel + 0.1 mg/mL CaneCPI-5 (Cg + Cane). Volunteers wore an appliance containing 4 specimens. Once/day, they applied the gel (except for Nt) (4 min/specimen). Erosive challenges were performed extra-orally (0.1% citric acid, 90 s, 4 × /day; ERO). Specimens were also abraded (toothbrush, 15 s/specimen, 2 × /day; ERO + ABR). Enamel wear was assessed by profilometry and relative surface reflection intensity (%SRI). Two-way RM-ANOVA/Sidak's tests and Spearman's correlation were used (p < 0.05). RESULTS: For profilometry, ERO + ABR promoted significantly greater wear when compared with ERO. There was a significant difference among all treatments. The lowest enamel loss occurred for Cg + Cane, followed by Cg + NaF, Cg, and Nt (p < 0.05). The %SRI was significantly lower for ERO + ABR when compared to ERO, only for the Nt group. The greatest %SRI was found for the Cg + NaF and Cg + Cane groups, which did not differ significantly, regardless of the conditions. The lowest %SRI was found for the Nt and Cg groups, which did not differ from each other, regardless of the conditions. The Nt group did not differ significantly from the Cg + NaF (ERO). There was a significant correlation between both analyses. CONCLUSION: The incorporation of CaneCPI-5 in the chitosan gel prevented erosive wear in situ. CLINICAL RELEVANCE: These results open a new perspective for the use of CaneCPI-5 in other application vehicles, such as chitosan gel.

RESUMEN

OBJECTIVE: This systematic review evaluated the effect of testosterone replacement therapy (TRT) in men with obesity having low testosterone levels (LTLs). DESIGN AND METHODS: Search strategies were performed in MEDLINE, Embase, LILACS, and CENTRAL databases. Two reviewers selected the studies, assessed the risk of bias, and extracted data from the included studies. A random-effects model was used to pool results across studies, and the Grading of Recommendations Assessment, Development, and Evaluation was used to evaluate the certainty of evidence. RESULTS: A total of 16 randomized controlled trials were included. With moderate certainty of the evidence, no difference was found between TRT and placebo regarding total adverse events, TRT led to a 2-kg lean body mass gain and slightly improved low-density lipoprotein (LDL), without effects on the blood pressure. Due to imprecision/heterogeneity, effects in cardiovascular events (relative risk: 0.52, 95% CI: 0.26 to 1.05, 7 trials, 583 participants), high-density lipoprotein, hematocrit, prostate-specific antigen, HbA1c, and quality of life were unclear. TRT was effective for waist circumference and BMI; however, large between-study heterogeneity was found, with 95% prediction intervals crossing the null effect line. Meta-regression revealed that the average age of participants was a significant modifier for both outcomes. CONCLUSION: TRT slightly improved the lean body mass and LDL in men with obesity having LTLs but did not affect the blood pressure. The effects of TRT on cardiovascular events, HbA1c, and quality of life are unclear. The mean age of participants significantly modified the effect of TRT on weight loss.

RESUMEN

BACKGROUND: Next generation sequencing (NGS) has been a handy tool in clinical practice, mainly due to its efficiency and cost-effectiveness. It has been widely used in genetic diagnosis of several inherited diseases, and, in clinical oncology, it may enhance the discovery of new susceptibility genes and enable individualized care of cancer patients. In this context, we explored a pan-cancer panel in the investigation of germline variants in Brazilian patients presenting clinical criteria for hereditary cancer syndromes or familial history. METHODS: Seventy-one individuals diagnosed or with familial history of hereditary cancer syndromes were submitted to custom pan-cancer panel including 16 high and moderate penetrance genes previously associated with hereditary cancer syndromes (APC, BRCA1, BRCA2, CDH1, CDKN2A, CHEK2, MSH2, MSH6, MUTYH, PTEN, RB1, RET, TP53, VHL, XPA and XPC). All pathogenic variants were validated by Sanger sequencing. RESULTS: We identified a total of eight pathogenic variants among 12 of 71 individuals (16.9%). Among the mutation-positive subjects, 50% were diagnosed with breast cancer and had mutations in BRCA1, CDH1 and MUTYH. Notably, 33.3% were individuals diagnosed with polyposis or who had family cases and harbored pathogenic mutations in APC and MUTYH. The remaining individuals (16.7%) were gastric cancer patients with pathogenic variants in CDH1 and MSH2. Overall, 54 (76.05%) individuals presented at least one variant uncertain significance (VUS), totalizing 81 VUS. Of these, seven were predicted to have disease-causing potential. CONCLUSION: Overall, analysis of all these genes in NGS-panel allowed the identification not only of pathogenic variants related to hereditary cancer syndromes but also of some VUS that need further clinical and molecular investigations. The results obtained in this study had a significant impact on patients and their relatives since it allowed genetic counselling and personalized management decisions.

RESUMEN

SUMMARY: The aim of this research was to analyze the morphology of the nasal septum and inferior nasal concha bone in class III facial deformities prior to orthodontic treatment in orthognathic surgery candidates. 40 subjects were included in this research. The inclusion criteria were an Angle class III, negative overjet and SNA angle less than 80º. Patients with facial asymmetry, facial trauma or who had undergone maxillofacial or ENT procedures were excluded. CBCT images were obtained for all the patients and the nasal septum deviation, morphology of inferior nasal concha bone and ostium of the maxillary sinus were analyzed and related to the complexity of the facial deformity expressed by the ANB angle and dental relations. The measurement was standardized by ICC and the data was analyzed using a chi square test and Spearman's coefficient with a p value < 0.005 for statistical significance. Nasal septal deviation was observed in 77.5 %. The deviation angle was 13.28º (±4.68º) and the distance from the midline to the most deviated septum was 5.56 mm (±1.8 mm) with no statistical relation to the complexity of the facial deformity. The deviated nasal septum showed inferior nasal concha bone hypertrophy on the concave side of the nasal septum deviation (p=0.049). The open or closed condition of the maxillary sinus ostium was not related to any conditions in the septum or complexity of the facial deformity. Inferior nasal concha bone hypertrophy could be related to nasal septal deviation. The nasal condition in a class III facial deformity could not differ from the general population; careful in orthognathic surgery as to be assume in the Le Fort I Osteotomy and nasal approach related to nasal septum deviation and inferior nasal concha bone.


RESUMEN: El objetivo de esta investigación fue analizar la morfología del septum y la concha nasal inferior en sujetos con deformidad facial clase III previo al tratamiento de ortodoncia preparatorio para cirugía ortognática. Fueron incluidos 40 sujetos en esta investigación. Los criterios de inclusión fueron la de presentar una clase III de Angle, overjet negativo y ángulo SNA menor que 80º. Sujetos con asimetría facial, trauma facial o quienes presentaron algún tipo de procedimiento maxilofacial o de otorrinolaringología fueron excluidos. Tomografía computadorizada cone beam (CBCT) fueron obtenidas para todos los sujetos donde le morfología del septum nasal, morfología de la concha nasal inferior y el ostium del seno maxilar fueron analizados y relacionados con la complejidad de la deformidad facial expresada como ángulo ANB y relaciones dentales. Las medidas fueron estandarizadas por el ICC y los datos fueron analizados utilizando la prueba chi cuadrado y coeficiente de Spearman con un valor de p<0,05 para obtener relaciones significativas. La desviación del septum nasal se observó en el 77,5 %; el ángulo de desvío fue de 13,28º (±4,68º) y la distancia de desvío del septum desde la línea media fue de 5,56 mm (±1,8 mm) sin diferencias estadísticas en relación a la complejidad de la deformidad. El desvío de septum nasal demostró hipertrofia de la concha nsal inferior en el lado cóncavo del septum desviado (p=0,049). La condición de ostium abierto o cerrado no fue relacionado con ninguna condición del septum nasal o complejidad de la deformidad facial. La hipertrofia de la concha nasal inferior se relacionó con el desvío de septum nasal. La condición nasal en deformidad facial de clase III no es diferente de la observada en la población general; cuidados deben ser realizados en cirugía ortognática para el desarrollo de la osteotomía de Le Fort I y aproximación nasal en relación al desvío de septum y probable alteración de la concha nasal inferior.

RESUMEN

The aim of this investigation was to define the volume and area of the airway in subjects with Class II and Class III skeletal deformity. A cross-sectional study was designed including subjects with facial deformity defined by Steiner's analysis in subjects with indication of orthognathic surgery who presented diagnosis by cone beam computerised tomography. We determined the measurements of maximum area, minimum area and volume of the airway. The data were compared using Spearman's test, with statistical significance defined as p<0.05. 115 subjects were included: 61.7 % Class II and 38.3 % Class III, mean age 27.8 years (± 11.6). A significant difference was observed in the area and volume measurements in the groups studied, with significantly smaller measurements found in Class II (p=0.034). The minimum area was 10.4 mm2 smaller in Class II patients than in Class III, while the general volume of the airway was 4.1 mm3 smaller in Class II than in Class III. We may conclude that Class II subjects present a smaller airway volume than Class III subjects.

RESUMEN

Abstract: There is little data in the literature concerning dermatologic admissions. Several diseases are seasonal in incidence and clinical worsening. We performed a survey of hospitalizations in the dermatology ward of a public hospital (April/2007 to May/2017). There were 1790 hospitalizations, whose main diagnoses were infectious dermatoses, neoplasias, psoriasis, bullous diseases and cutaneous ulcers. In winter, there were fewer hospitalizations for bacterial infections and urticaria, but more for leprosy. In summer, there were fewer hospitalizations for systemic and subcutaneous mycoses, but more for zoodermatoses and erythema multiforme. In the fall, more patients were admitted with mycoses. Spring favored urticaria and angioedema, but less cases of erythema multiforme and diabetic foot.

RESUMEN

El objetivo de esta investigación es determinar la inclinación de incisivos maxilares en sujetos con maloclusión de clase III. Se incluyeron 35 sujetos que presentaran deformidad facial de clase III (DF-III) para analizar la tomografía computarizada de haz cónico; las mediciones se realizaron para los cuatro incisivos maxilares identificando el plano palatino considerado entre espina nasal anterior y posterior y el eje axial dentario obtenido por la unión entre punto coronal y punto apical; los resultados mostraron angulaciones de 111,6 a 113,7 para los incisivos, lo cual permite obtener valores cercanos a la normalidad de angulación dentaria. Se concluye que los sujetos seleccionados presentan una angulación dentaria adecuada para la realización de procedimientos de cirugía primero.


The objective of this research was to determine the inclination of maxillary incisors in subjects with class III malocclusion. Were included 35 subjects with Class III facial deformity (DF-III) to analyze cone beam computed tomography; measurements were realized in the four maxillary incisors identifying the palatal plane considered between anterior and posterior nasal spine and dental axial axis from the union between coronal point and apical point; The results showed angulations from 111.6 to 113.7 for the incisors, which allows estimation of values close to normal dental angulation. It is concluded that the selected subjects present adequate dental angulation to perform surgery first.

RESUMEN

The objective of this study was to determine the effects of method and clinician on stallion sperm morphology evaluation. Five clinicians evaluated 60 semen samples using wet-mount preparations with phase-contrast, eosin/nigrosin-stained semen smears, and Papanicolaou-stained semen smears. There were significant differences among methods for all sperm morphology categories and most intra-class correlation coefficients were only fair to moderate. The use of wet-mount preparations facilitated detection of acrosome defects, nuclear vacuoles, and cytoplasmic droplets when compared to stained smears. Smearing stallion semen samples onto slides increased the proportion of detached sperm heads. In addition, acrosome defects, nuclear vacuoles, rough/swollen midpieces, and cytoplasmic droplets were difficult to observe with Papanicolaou stain; this method resulted in overestimation of normal sperm when compared to other methods. There were significant differences among clinicians for all sperm morphology classification categories. In conclusion, this study demonstrated that sperm morphology evaluation results varied, depending on the evaluation method and clinician. Wet-mount preparation with phase-contrast microscopy appeared to be more sensitive for identification of abnormal stallion sperm when compared to stained smears. Veterinary andrology laboratories should invest in training, continuing education, proficiency testing, and other quality control measures to minimize the variation of sperm morphology evaluation results among clinicians.

RESUMEN

A teoria de Watson defende o cuidado como uma ciência humana desenvolvida a partir de fundamentos filosóficos e sistemas de valores humanistas. Essa perspectiva é baseada em uma relação ontológica por estar atrelada a uma visão mundial de unidade. Destarte, o objetivo deste estudo é descrever a Teoria do Cuidado Transpessoal de Jean Watson com base na etapa da descrição do Modelo de Avaliação de Teorias de Meleis. A metodologia utilizada foi a análise interpretativa com a descrição do modelo especificamente nos componentes estruturais da teoria. Concluímos que o cuidado transpessoal apresenta fundamental valia para o enriquecimento profissional e favorece a recuperação do paciente, pois prioriza a integralidade da atenção, utilizando procedimentos tecnológicos e a consideração de suas necessidades socioculturais e espirituais.

RESUMEN

The objective of the present study was to characterize the effects of nutrition on circulating concentrations of metabolic hormones, gonadotropins, and testosterone during sexual development in bulls. Nutrition regulated the hypothalamus-pituitary-testes axis through effects on the GnRH pulse generator in the hypothalamus and through direct effects on the testes. Pituitary function (gonadotropin secretion after GnRH challenge) was not affected by nutrition. However, nutrition affected LH pulse frequency and basal LH concentration during the early gonadotropin rise (10-26 weeks of age). There were close temporal associations between changes in insulin-like growth factor-I (IGF-I) concentrations and changes in LH pulse frequency, suggesting a role for IGF-I in regulating the early gonadotropin rise in bulls. The peripubertal increase in testosterone concentration was delayed in bulls with lesser serum IGF-I concentrations (low nutrition), suggesting a role for IGF-I in regulating Leydig cell function. Serum IGF-I concentrations accounted for 72 and 67% of the variation in scrotal circumference and paired-testes volume, respectively (at any given age), indicating that IGF-I may regulate testicular growth. Bulls with a more sustained elevated LH pulse frequency during the early gonadotropin rise (high nutrition) had greater testicular mass at 70 weeks of age relative to the control group (medium nutrition), despite no differences in metabolic hormone concentrations after 26 weeks of age. Therefore, gonadotropin-independent mechanism regulating testicular growth might be dependent on previous gonadotropin milieu.
