Dentomaxillofac Radiol 2022; 51:20220156. [PMID: 35926079 PMCID: PMC9717399 DOI: 10.1259/dmfr.20220156] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2022] [Revised: 07/13/2022] [Accepted: 07/22/2022] [Indexed: 12/15/2022] Open
Abstract
OBJECTIVES To determine the prevalence of middle mesial root canal (MMC) in a Brazilian subpopulation, verify whether its presence is related to anatomical characteristics of the tooth, and propose a classification using cone-beam computed tomography (CBCT). METHODS CBCT scans of 284 patients were evaluated by 2 radiologists to determine the presence of the MMC in mandibular first and second molars. Subsequently, the mesiodistal and buccolingual measurements of the mesial roots were obtained; the measurements between the root canals, and from MMC to the mesiobuccal canal and to the mesiolingual canal were also obtained. The MMC was classified according to its relationship with mesiobuccal and mesiolingual canals. The data were analyzed using χ2 and Fisher's exact test, multiple logistic regression analysis, Student's t-test, κ and intraclass correlation coefficient (p < 0.05). RESULTS The intraexaminer agreements for the presence of the MMC and the measurements were considered almost perfect (0.953 and 0.999, respectively). Of 216 mandibular first molars, 11.1% had the MMC, and of 228 mandibular second molars, only 1.75% had the MMC. The presence was significant higher in the mandibular first molar (p < 0.0001). The buccolingual measurement and the measurement between mesiobuccal and mesiolingual canals were higher in teeth with MMC (p = 0.024 and p = 0.005, respectively). It was possible to classify the configuration of MCC into four types: independent (60.7%), confluent (14.3%), mesiolingual confluent (14.3%), and mesiobuccal confluent (10.7%). CONCLUSIONS The prevalence of MMC is more pronounced in mandibular first molars and anatomical measurements, such as greater measurement between mesiobuccal and mesiolingual canals, may alert clinicians to its presence. It was found four types of configurations of MMC.

Abstract
Introduction The novel Coronavirus (SARS-CoV-2), responsible for severe acute respiratory syndrome, has emerged as a threat to humans since December 2019, and the search for a better understanding of the pathophysiology of coronavirus disease 2019 (COVID-19) and its definitive treatment is still in progress. Objective To evaluate the plasma pro- and anti-inflammatory cytokines in COVID-19 patients and their associations with the disease severity and outcome. Methods Reverse-Transcriptase Polymerase Chain Reaction (RT-PCR)-confirmed COVID-19 unvaccinated patients at the Hospital de Clínicas (HC), UNICAMP, Campinas, SP, were enrolled. Clinical and laboratory data were extracted from the medical records, and the plasma cytokines levels were quantified using LUMINEX and ELISA. Results There were 154 COVID-19 patients (99 survivors and 55 non-survivors) with male:female of 1.4:1, and a median age of 60 years. The non-survivors were older than survivors (65 vs. 55 years, p < 0.0001); and coronary artery disease and autoimmunity, disease severity, and oxygen therapy, intensive care, and intubation were associated with mortality. Non-survivors had higher leukocyte and neutrophil counts, and RDW and lower lymphocyte count at diagnosis. Non-survivors had higher levels of pro-inflammatory (TNF-α, IL-6, IFN-γ, CCL3, IL-17/IL-17A, IL-8, G-CSF, CCL2/MCP-1) and anti-inflammatory (IL-1ra and IL-27) cytokines, but lower TGF-β levels than the survivors. TNF-α levels were positively correlated with all studied cytokines except TGF-β, while TGF-β levels were negatively correlated with TNF-α, IL-6, CCL3, G-CSF, and IL-27. IL-27 levels were significantly correlated with all the cytokines except IL-37 and IL-17E. More than half (55.2%) of our patients had severe COVID-19, 18.8% had moderate, 16.2% had critical, 5.2% had mild, and 4.5% were asymptomatic. Majority of the patients (68.2%) required ICU care and had higher TNF-α, IL-6, IL-8, IL-17, CCL3, CCL2, IL-1ra, and IL-27 than others. 59.7% of the patients required endotracheal intubation and had higher TNF-α, IL-6, IL-8, CCL3, CCL2, and IL-1ra than those who did not have intubation. TNF-α, IL-6, and IL-8 had the highest Area Under the Receiver Operating Characteristics (AUROC) curve, sensitivity, and specificity for predicting mortality in these COVID-19 patients. Discussion and conclusion The altered levels of pro- and anti-inflammatory cytokines support the role of SARS-CoV-2 in inducing cytokine storm, and higher concentrations seen in the deceased patients meant a more severe storm. Also, the increased leukocytes and neutrophils in our patients could have led to the release of reactive oxygen species, and end-organ damage, thus leading to poor outcomes. This study showed that the levels of these cytokines could be used as markers of mortality in COVID-19. It is possible to suggest that TNF, IL-6, and IL-8 levels at diagnosis could be efficient predictors of fatal outcomes in COVID-19 patients. If properly measured at diagnosis, these markers could be useful for triaging and predicting the outcome of COVID-19, thus guiding the treatment of the COVID-19.

Abstract
The complex pathophysiology of sickle cell anemia (SCA) involves intravascular hemolytic processes and recurrent vaso-occlusion, driven by chronic vascular inflammation, which result in the disease’s severe clinical complications, including recurrent painful vaso-occlusive episodes. Hydroxyurea, the only drug frequently used for SCA therapy, is a cytostatic agent, although it appears to exert nitric oxide/soluble guanylyl cyclase (sGC) modulating activity. As new drugs that can complement or replace the use of hydroxyurea are sought to further reduce vaso-occlusive episode frequency in SCA, we investigated the effects of the sGC agonists BAY 60-2770 (sGC activator) and BAY 41-2272 (sGC stimulator) in the presence or absence of hydroxyurea on SCA vaso-occlusive mechanisms and cell recruitment both ex vivo and in vivo. These agents significantly reduced stimulated human SCA neutrophil adhesive properties ex vivo in association with the inhibition of surface β2-integrin activation. A single administration of BAY 60-2770 or BAY 41-2272 decreased tumor necrosis factor cytokine–induced leukocyte recruitment in a mouse model of SCA vaso-occlusion. Importantly, the in vivo actions of both agonists were significantly potentiated by the coadministration of hydroxyurea. Erythroid cell fetal hemoglobin (HbF) elevation is also a major goal for SCA therapy. BAY 41-2272 but not BAY 60-2770 at the concentrations employed significantly induced γ-globin gene transcription in association with HbF production in cultured erythroleukemic cells. In conclusion, sGC agonist drugs could represent a promising approach as therapy for SCA, for use either as stand-alone treatments or in combination with hydroxyurea.

Abstract
Hereditary anemias are a group of heterogeneous disorders including hemolytic anemias and hyporegenerative anemias, as congenital dyserythropoietic anemia (CDA). Causative mutations occur in a wide range of genes leading to deficiencies in red cell production, structure, or function. The genetic screening of the main genes is important for timely diagnosis, since routine laboratory tests fail in a percentage of the cases, appropriate treatment decisions, and genetic counseling purposes. A conventional gene-by-gene sequencing approach is expensive and highly time-consuming, due to the genetic complexity of these diseases. To overcome this problem, we customized a targeted sequencing panel covering 35 genes previously associated to red cell disorders. We analyzed 36 patients, and potentially pathogenic variants were identified in 26 cases (72%). Twenty variants were novel. Remarkably, mutations in the SPTB gene (β-spectrin) were found in 34.6% of the patients with hereditary spherocytosis (HS), suggesting that SPTB is a major HS gene in the Southeast of Brazil. We also identified two cases with dominant HS presenting null mutations in trans with α-LELY in SPTA1 gene. This is the first comprehensive genetic analysis for hereditary anemias in the Brazilian population, contributing to a better understanding of the genetic basis and phenotypic consequences of these rare conditions in our population.

Abstract
The impaired bioavailability of endogenous nitric oxide (NO) in sickle cell anemia (SCA) may be influenced by polymorphisms in the endothelial nitric oxide synthase gene (eNOS). We compared allelic/genotypic frequencies of the eNOS polymorphisms T-786C, VNTR4a/b and G894T between 89 adult SCA patients and 100 healthy controls, and investigated the relationship between these SNPs and markers of hemolysis [lactate dehydrogenase (LDH), indirect bilirubin (IB) and reticulocyte counts], inflammation [interleukins IL-1β, IL-6, IL-8, Tumor Necrosis Factor (TNF-α) and C-reactive protein (CRP)] and endothelial dysfunction (ED) [soluble vascular cell adhesion molecule-1 (sVCAM-1), soluble intercellular adhesion molecule-1 (sICAM-1), soluble L-selectin (sL-selectin), von Willebrand Factor (vWF) antigen and D-dimers] in the patients. The frequencies of the mutant -786C allele and -786C/C genotype were significantly higher in patients (p = 0.02 and p = 0.04, respectively) but not significantly correlated with the markers. For VNTR4a/b and G894T, the allelic/genotypic frequencies did not statistically differ between patient and control groups. Patients carrying the 4a allele and those with the 894G/G genotype showed a significant decrease in IB (p = 0.02 and p = 0.04, respectively), and only patients with the 4a allele exhibited reduced IL-1β (p = 0.01). The correlation profiles between markers of inflammation and ED significantly differed between patients carrying the mutant alleles and those with wild-type genotypes. This appears to be the first report on the relationship between eNOS gene polymorphisms and markers of hemolysis, inflammation and ED in Brazilian SCA patients. Our results indicate that the SNPs analyzed may influence the phenotypic variability of these patients.

Abstract
Background Sickle leg ulcer (SLU) is a chronic and debilitating complication of sickle cell disease (SCD) associated with huge physical and psychosocial discomfort. The occurrence of SLU has remained steady despite successful preventive strategies and advances in SCD care. Although multifactorial factors have been implicated in SLU, these are not fully understood, and data on how these relate to young Nigerian SCD patients are scanty. Aims This study aims to evaluate the sociodemographic, clinical, and laboratory markers of SLU in a young Nigerian SCD cohort. Patients and Methods This study involved 109 young SCD patients and 67 healthy peers. The sociodemographic and laboratory parameters of the participants were examined in addition to the evaluation of the SCD cohort for SLU. Results Only the HbSS patients had SLU. This was found in six of them giving a prevalence of 5.9% (6/101). Their median age was 17, range 14-21 years. There was a preceding history of trauma in 4 (66.7%), and this included a case of traditional scarifications for local therapeutic purposes. Two of the three (66.7%) males with SLU also had priapism (P = 0.0132). Patients with SLU were older, had less frequent bone pain crises, and significantly belonged to the low socioeconomic class (P < 0.05). Although patients with SLU had relatively higher lactate dehydrogenase, platelet count, aspartate transaminase, bilirubin, white blood cell, and lower Hb concentration and HbF, these did not attain statistical significance (P > 0.05). Conclusion This study confirms that SLU is common among young SCD patients with HbSS genotype, low socioeconomic background, and older age. It also suggests that SLU could be more related to hemolysis-associated SCD phenotypes among the patients.

Abstract
Our purpose was to compare the accuracy and reliability of linear measurements for Le Fort I osteotomy using volume rendering software. We studied 11 dried skulls and used cone-beam computed tomography (CT) to generate 3-dimensional images. Linear measurements were based on craniometric anatomical landmarks that were predefined as specifically used for Le Fort I osteotomy, and identified twice each by 2 radiologists, independently, using Dolphin imaging version 11.5.04.35. A third examiner then made physical measurements using digital calipers. There was a significant difference between Dolphin imaging and the gold standard, particularly in the pterygoid process. The largest difference was 1.85mm (LLpPtg L). The mean differences between the physical and the 3-dimensional linear measurements ranged from -0.01 to 1.12mm for examiner 1, and 0 to 1.85mm for examiner 2. Interexaminer analysis ranged from 0.51 to 0.93. Intraexaminer correlation coefficients ranged from 0.81 to 0.96 and 0.57 to 0.92, for examiners 1 and 2, respectively. We conclude that the Dolphin imaging should be used sparingly during Le Fort I osteotomy.

Abstract
OBJECTIVE The purpose of this study was to compare the precision and accuracy of linear measurements for Le Fort I osteotomy performed by two different imaging software programs and obtained from three-dimensional cone beam CT (3D-CBCT) images. METHODS The study population consisted of 11 dried skulls submitted to CBCT, which generated 3D images. Linear measurements were based on craniometric anatomical landmarks pre-defined by the authors as specifically used for Le Fort I osteotomy and were identified by two radiologists twice each, independently, using Vitrea 3.8.1 (Vital Images Inc., Plymouth, MN) and open-source digital imaging communication in medicine viewer OsiriX 1.2 64-bit (Pixmeo, Geneva, Switzerland). Subsequently, a third examiner made physical measurements using a digital caliper (167 series; Mitutoyo Sul Americana Ltd, Suzano, SP, Brazil). RESULTS The results demonstrated a statistically significant difference between OsiriX and the gold standard, especially in the pterygoid process (TPtg L = 0.019, LLpPtg R = 0.016 and LLpPtg L = 0.012). Vitrea showed no statistical difference in comparison with the gold standard, and showed a high level of accuracy in all the measurements performed. The major difference found was 0.42 mm (LLpPtg R). Interexaminer analysis ranged from 0.90 to 0.97 using Vitrea and from 0.8 to 0.97 using OsiriX. Intraexaminer correlation coefficient ranged from 0.90 to 0.98 and from 0.84 to 0.98 for Examiners 1 and 2, respectively, using Vitrea and from 0.93 to 0.99 for Examiner 1 and from 0.64 to 0.96 for Examiner 2 using OsiriX. CONCLUSION Vitrea may be considered as precise and accurate, insofar as it was able to perform all the 3D linear measurements. On the other hand, linear measurements performed using OsiriX were not successful in producing accurate linear measurements for Le Fort I osteotomy.
