RESUMEN

This article describes how the Gross Motor Ability Estimator (GMAE) software can provide important information based on the Gross Motor Function Measure (GMFM)-66 score of a child with congenital Zika syndrome.A child was assessed at 9, 17, and 25 months of age through the GMFM-66. At 2 years, the child's gross motor ability was estimated and classified according to the Gross Motor Function Classification System (GMFCS).At 2 years of age, the child in this case required assistance to roll and was unable to maintain antigravity trunk posture in sitting position, typical abilities of GMFCS level V.GMAE can be useful to guide health professionals that care for children with lifelong physical and developmental care needs. This is the first study that demonstrated how to use the GMAE in this specific population.

RESUMEN

AIMS: The purpose of this study was to assess the current clinical practice of physiotherapists and occupational therapists on early detection and early intervention for children with cerebral palsy (CP) in Brazil. METHODS: This was a cross-sectional study. A purpose-developed electronic survey was disseminated across the country to physiotherapists and occupational therapists working with young children with or at risk of CP. RESULTS: A total of 205 anonymous respondents were included. Most participants (64.4%) agree that the diagnosis of CP can be made before 6 months of age. General Movements Assessment (26.8%) and Hammersmith Infant Neurological Examination (37.1%) were used infrequently. Infants at risk for CP receive therapy twice a week or more by 58.5% of therapists, 93.2% identified parents' goals as the most important factor in customizing the early intervention program. The most frequent intervention strategies for this age group were active stimulation of the child (n = 182), family training (n = 161), strategies to optimize the environment (n = 143), and neurodevelopmental treatment/Bobath (n = 99). CONCLUSIONS: Currently, pediatric physiotherapists and occupational therapists in Brazil do not fully incorporate best practice tools for early identification of children with CP, nor sufficient best evidence-based interventions.

RESUMEN

STATEMENT OF PROBLEM: Whether oral rehabilitation with dental implants in patients with Down syndrome leads to an increased complication rate is unclear. PURPOSE: The purpose of this systematic review was to determine the effectiveness of dental implants placed in patients with Down syndrome and whether the condition is a risk factor or contraindication for dental implant placement. MATERIAL AND METHODS: Searches were conducted in 6 databases, including the non-peer-reviewed literature, up to February 2021 by 2 independent reviewers according to established inclusion and exclusion criteria to answer this question: Is Down syndrome a risk factor or contraindication for oral rehabilitation with dental implants? RESULTS: A total of 655 studies were initially found in the databases. Five were included in this systematic review, all of which were observational studies. A total of 50 patients with 186 implants were evaluated, with a reported effectiveness of 79.1%. The risk of bias assessment determined that 3 of the 5 studies had a high risk of bias. CONCLUSIONS: Treatment with dental implants in patients with Down syndrome is a suitable option, but more complications are to be expected than with patients without this condition. Controlled studies with better methodological design and less risk of bias should be developed to improve the scientific evidence for the treatment of these patients.

RESUMEN

Coronaviridae is a family of single-stranded positive enveloped RNA viruses. This article aimed to review the history of these viruses in the last 60 years since their discovery to understand what lessons can be learned from the past. A review of the PubMed database was carried out, describing taxonomy, classification, virology, genetic recombination, host adaptation, and main symptoms related to each type of virus. SARS-CoV-2 is responsible for the ongoing global pandemic, and SARS-CoV and MERS-CoV were responsible for causing severe respiratory illness and regional epidemics in the past while the four other strains of CoVs (229-E OC43, NL63, and HKU1) circulate worldwide and normally only cause mild upper respiratory tract infections. Given the enormous diversity of coronavirus viruses in wildlife and their continuous evolution and adaptation to humans, future outbreaks would undoubtedly occur. Restricting or banning all trade in wild animals in wet markets would be a necessary measure to reduce future zoonotic infections.

RESUMEN

The objective of this systematic review is to evaluate the effectiveness of low-level laser therapy in the treatment of herpes labialis. The searches were carried out independently by 2 researchers and the articles were selected through the electronic databases according to the inclusion and exclusion criteria previously established. Initially, 480 articles were found, of which 7 randomized clinical trials and 1 clinical trial were selected. In total, 928 patients were included. In the meta-analysis, the mean healing time for laser use was significant, showing a mean reduction of 1.37 [CI 95% = 0.92 to 1.82] days for tissue healing (p < 0.0001). In the meta-analysis to evaluate the time for crust formation, there was no significant difference between the groups and no significant reduction in the mean time for crust formation (p = 0.150). Only one of the selected studies had a low risk of bias. The use of low-level laser proved to be effective in the treatment of herpes labialis. However, due to the high risk of bias in the included studies, there is a need to carry out new standardized studies to prove the effectiveness of this therapy.

RESUMEN

BACKGROUND: The aim of the present study was to evaluate the efficacy of pentoxifylline and tocopherol for the management of osteoradionecrosis of the jaws. METHODS: Twenty-five patients diagnosed with osteoradionecrosis of the jaws treated with pentoxifylline 400 mg + tocopherol 400 mg three times daily (tid) were evaluated. Clinical records and image tests were reviewed. All patients were previously submitted to head and neck radiation therapy and presented with a clinical and radiographic diagnosis of osteoradionecrosis of the jaws. RESULTS: Following therapy with pentoxifylline and tocopherol, 76% (19/25) of the patients showed complete mucosal healing, in which 47.3% (9/19) did not undergo sequestrectomy. From this particular group, 77.7% (7/9) were in stage I and 33.3% (3/9) used the protocol for up to 3 months. Among those who underwent to sequestrectomy, complete mucosal healing was observed in 52.7% (10/19). Among these, 60% (6/10) were in stage I and 100% of the patients were using the protocol for more than 3 months. In all other patients, partial healing of the mucosa was observed since they presented advanced disease. These represented 24% of the sample (6/25), 66.6% (4/6) were in stage III, and 60% (4/6) used the protocol for over 6 months. CONCLUSION: Pentoxifylline and tocopherol may provide effective management of osteoradionecrosis of the jaws, and the association with sequestrectomy may avoid major surgical procedures.

RESUMEN

OBJECTIVE: A systematic review and meta-analysis was carried out to verify evidence regarding the efficacy and safety of the clinical applicability of natural products in the prevention and treatment of oral mucositis induced by chemotherapy and/or radiotherapy. METHODOLOGY: An electronic research according to the PICOS strategy, using the terms "natural products" and "oral mucositis," was carried out at Pubmed, Cochrane, Embase, and "gray literature." The stages of eligibility, data extraction, and quality assessment of the studies were carried out independently and in duplicate. RESULTS: The number of studies identified as eligible was 151, including 47 randomized controlled trials, reporting a total of 3075 participants undergoing some therapy with natural products on oral mucositis. The included clinical trials covered a variety of 31 types of natural products. Considering the risk of bias of the clinical trials, 24 studies (51.1%) were considered to have a low overall risk of bias, nine (19.1%) were at moderate risk, and 14 clinical trials (29.8%) were at high risk of bias. Honey was the most assessed natural agent. Fourteen studies (3.4%) reported that natural agents reduced pain. CONCLUSION: The results of the meta-analysis support a positive effect of honey and Aloe vera in reducing mucositis in patients receiving cancer therapy. CLINICAL RELEVANCE: The results found add relevant information to the scientific community regarding the prevention and treatment of mucositis. Graphical abstract.

RESUMEN

The purpose of this cross-sectional, quantitative study was to evaluate the salivary flow of 20 patients undergoing conventional 2-dimensional radiotherapy in the head and neck region. Unstimulated salivary flow was measured with the spitting technique. In addition, xerostomia was evaluated through the Eisbruch grading system and the Xerostomia Inventory (XI). The patients were evaluated 3 times: D0, before the first radiotherapy session; D17, after the 17th radiotherapy session; and D35, after the last radiotherapy session. Most of the patients in the present study were men (70%). The larynx was the most frequent site of cancer in this sample (45%). The most prevalent oral alteration during radiotherapy was odynophagia (75%). The analysis of subjective symptoms of xerostomia revealed no statistically significant differences (P = 0.059). However, statistically significant differences in the XI were found, with scores increasing from D0 to D17 and D35 (P = 0.004). With regard to the objective symptoms of xerostomia, most patients started treatment in grade 1 and remained in the same category at the end of radiation. There was a slight increase in salivary volume during treatment, an atypical finding that can probably be explained by the use of low-level laser, which was applied to prevent oral mucositis in all of the patients. The mean total radiation dose (65 Gy) received by the patients in the present sample did not appear to influence the XI values or salivary volume. The data reinforced the subjective nature of xerostomia, which is not always related to hyposalivation.

RESUMEN

The objectives of this study were to determine the effectiveness of a mucoadhesive tablet of pilocarpine, 5 mg, for the treatment of xerostomia and verify its pharmacokinetic profile. The randomized, double-blind, crossover clinical trial involved 25 older adults (60 to 80 years) with xerostomia and hyposalivation who were randomly divided into groups A and B. Once daily, for 7 days, group A used a mucoadhesive tablet containing pilocarpine, while group B used a mucoadhesive tablet without the active ingredient (first intervention). After 7 days of washout (no treatment), use of the medications resumed for 7 days, with a crossover between groups (second intervention). Xerostomia was evaluated through a shortened version of the Summated Xerostomia Inventory-Dutch Version, and the unstimulated salivary flow (USF) and stimulated salivary flow (SSF) of the patients were measured. The patients were evaluated at baseline and 7, 14, and 21 days. Then, the pharmacokinetic profiles of mucoadhesive and conventional oral pilocarpine tablets were compared using saliva obtained from 8 patients. Both of the interventions resulted in a significant reduction in Summated Xerostomia Inventory scores and a significant increase in the mean USF (P < 0.05). A statistically significant increase in the mean SSF only occurred when pilocarpine was administered (P < 0.05). No significant adverse effects were found. The mucoadhesive tablet resulted in much higher salivary concentrations of pilocarpine than did the conventional oral tablet. Both formulations of the mucoadhesive tablet, with or without pilocarpine, relieved patients' dry mouth symptoms. Trial registration: Registro Brasileiro de Ensaios Clinicos (ReBEC) No. RBR-9qdnws.

RESUMEN

AIM: To describe the standardized neurodevelopmental outcomes after the first year of life in children with congenital Zika syndrome (CZS) and those exposed to Zika virus (ZIKV) during fetal life, but without microcephaly at birth. METHOD: This scoping review included observational studies about the standardized neurodevelopmental outcome in children with CZS or exposed to ZIKV, but without microcephaly, assessed after 12 months of age. The databases searched were MEDLINE/Pubmed, LILACS, Scielo, Scopus, PsycINFO, CINAHL, and Embase. Risk of bias was assessed with the Joanna Briggs Institute Critical Appraisal Checklists. RESULTS: Seventeen papers were included: 12 focused on children with CZS, four on children born without microcephaly, and one described both. Only one of the studies about CZS reported a child with microcephaly and typical development; the remainder described a severe pattern of global developmental delay and cerebral palsy. The prevalence of epilepsy was 74.6%. In the reports about children born without microcephaly, 6.9% to 8.7% had some domain with a score below -2 SD, and three children developed autism spectrum disorder. INTERPRETATION: CZS is associated with severe global developmental delay and cerebral palsy after 1 year of age. In children born without microcephaly, although most have typical development, some may be at risk for impairments.

RESUMEN

OBJECTIVE: To describe oral alterations in children with congenital Zika syndrome (CZS). METHODS: This was a case series, whose research instrument was a structured questionnaire, associated with the use of medical record data and extra and intraoral clinical examination. RESULTS: Thirty-two children were evaluated, the majority male (18/32%-56.3%), mean age 22 months (SD = 2.71). It was also observed that the majority of the patients (19/32%-59.4%) presented a low family income. All the children had a mean head circumference of 29.43 cm (SD = 1.42). Regarding the alterations, an ogival-shaped palate was observed in 14 children (43.7%), and delayed chronology of eruption was observed in 15 children (46.9%), of whom 7 children (21.9%) did not present eruption of the upper left lateral incisor (p = .0002) and upper right lateral incisor (p = .002) until the moment of analysis. Additionally, 03 children with yellowish dental pigmentation were identified in erupted teeth after the onset of phenobarbital use. Enamel hypoplasia was identified in 9 children (28.1%) and only one child with ankyloglossia. CONCLUSION: CZS may present delayed chronology of eruption, ankyloglossia, ogival-shaped palate, and enamel hypoplasia, requiring dental follow-up aimed at prevention, promotion, and rehabilitation of the health of these children.

RESUMEN

OBJECTIVE: The aim of this study was to evaluate the orofacial parameters of systemic sclerosis (SSc) and its related systemic features. SUBJECTS AND METHODS: A descriptive case-control study was performed from November 2015 to October 2016. Ninety-three individuals were included and divided into SSc group (n = 50) and healthy controls (C, n = 43). RESULTS: Systemic sclerosis individuals were mostly women (43/50, 86%), with a mean age of 46 years (±11.6 years). Telangiectasia (42/50, 84%) and reduced mouth opening (35/50, 70%) were the most frequent orofacial findings. The periodontitis frequency was much higher in SSc individuals than in healthy controls (90.7% × 48.83%; p < .001). In addition, SSc individuals presented a distinctive pattern of periodontitis, with low probing pocket depth (2 ± 0.65 mm × 2 ± 0.24; p < .001), higher gingival recession (4 ± 2.13 × 0.14 ± 0,22; p < .001), higher periodontal attachment loss (6 ± 1.34 mm × 2 ± 0.43, p < .001), and lower gingival bleeding index values (7.05 ± 7.25 × 21.57 ± 15.66; p < .001). CONCLUSIONS: Orofacial manifestations were common in SSc and included a unique pattern of periodontal manifestation, characterized by lower gingival bleeding index, higher periodontal attachment loss, and low probing depth.

RESUMEN

We describe a case of a 20-month-old girl with probable congenital Zika virus infection and normal neurodevelopment, despite microcephaly and abnormal neuroimaging. This case raises questions about early prognostic markers and draws attention to the need for investigation in suspected Zika cases, even if the child's early neurodevelopment is normal.

RESUMEN

Schwannomas are uncommon benign tumors arising in the nerve-supporting Schwann cells. Intraoral lesions usually present in the tongue or floor of the mouth as a submucosal nodule, while the palate is rarely affected. A 26-year-old white man presented with an asymptomatic submucosal fibroelastic nodule in the hard palate. The 2 × 2-cm lesion was covered by normal-appearing mucosa. Under the working diagnosis of minor salivary gland tumor, an incisional biopsy was performed, and analysis revealed an encapsulated tumor with a well-defined biphasic pattern: hypercellular areas with spindled cells arranged in palisades and less cellular areas formed by irregular arranged masses of elongated cells and fibers. The diagnosis of schwannoma was rendered, and the lesion was excised together with periosteum. No recurrence was observed after 30 months of follow-up. Palatal nodules usually present as minor salivary gland tumors; rarer lesions, such as schwannomas, represent a clinical diagnostic challenge. Clinicians should consider schwannoma in the differential diagnosis for palatal nodules and manage them with incisional biopsy and prompt treatment.

RESUMEN

The aim of this study was to evaluate the influence of low-level laser therapy (LLLT) with different parameters and wavelengths on nitric oxide (NO) release and cell viability. Irradiation was performed with Ga-Al-As laser, continuous mode and wavelengths of 660 and 808 nm at different energy and power densities. For each wavelength, powers of 30, 50, and 100 mW and times of 10, 30, and 60 s were used. NO release was measured using Griess reaction, and cell viability was evaluated by mitochondrial reduction of bromide 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) to formazan. LLLT promoted statistically significant changes in NO release and MTT value only at the wavelength of 660 nm (p < 0.05). LLLT also promoted an increase in the NO release and cell viability when the energy densities 64 (p = 0.04) and 214 J/cm2 (p = 0.012), respectively, were used. LLLT has a significant impact on NO release without affecting cell viability, but the significance of these findings in the inflammatory response needs to be further studied.

RESUMEN

OBJECTIVE: The aim of this study was to evaluate the influence of Th17 polymorphisms on the susceptibility or severity of rheumatoid arthritis (RA) and Sjögren's syndrome (SS). MATERIALS AND METHODS: The study sample comprised 206 individuals of both genders divided into three groups: exclusive rheumatoid arthritis (RA-100 patients), rheumatoid arthritis and Sjögren's syndrome (RA/SS-31 patients), and healthy controls (C-75 individuals). All the individuals were submitted to clinical evaluation, unstimulated sialometry, and Schirmer test; some patients with RA were also submitted to minor salivary gland biopsy for definition of SS diagnosis. Saliva samples were collected for isolation of DNA and genotyping of Th17 genes; IL-17A (-197G/A) and IL-17F (7488T/C). RESULTS: IL-17A (-197G/A) and IL-17F (7488T/C) SNPs were not associated with susceptibility to RA or secondary SS (sSS, p > 0.05 for both SNPs). In addition, they did not influence RA activity or clinical markers of SS. CONCLUSION: IL-17A (-197G/A) and IL-17F (7488T/C) polymorphisms are not associated with the susceptibility nor to the severity of RA and sSS in the studied population. CLINICAL RELEVANCE: A better understanding of the pathogenesis of SS is demanded to an adequate treatment as well as to the development of new management strategies.

RESUMEN

OBJECTIVES: The goal of this study is to contribute to a better quantitative description of the early stages of osseointegration, by application of fractal, multifractal, and lacunarity analysis. MATERIALS AND METHODS: Fractal, multifractal, and lacunarity analysis are performed on scanning electron microscopy (SEM) images of titanium implants that were first subjected to different treatment combinations of i) sand blasting, ii) acid etching, and iii) exposition to calcium phosphate, and were then submersed in a simulated body fluid (SBF) for 30 days. All the three numerical techniques are applied to the implant SEM images before and after SBF immersion, in order to provide a comprehensive set of common quantitative descriptors. RESULTS: It is found that implants subjected to different physicochemical treatments before submersion in SBF exhibit a rather similar level of complexity, while the great variety of crystal forms after SBF submersion reveals rather different quantitative measures (reflecting complexity), for different treatments. In particular, it is found that acid treatment, in most combinations with the other considered treatments, leads to a higher fractal dimension (more uniform distribution of crystals), lower lacunarity (lesser variation in gap sizes), and narrowing of the multifractal spectrum (smaller fluctuations on different scales). CONCLUSION: The current quantitative description has shown the capacity to capture the main features of complex images of implant surfaces, for several different treatments. Such quantitative description should provide a fundamental tool for future large scale systematic studies, considering the large variety of possible implant treatments and their combinations. CLINICAL RELEVANCE: Quantitative description of early stages of osseointegration on titanium implants with different treatments should help develop a better understanding of this phenomenon, in general, and provide basis for further systematic experimental studies. Clinical practice should benefit from such studies in the long term, by more ready access to implants of higher quality.

RESUMEN

Nail involvement in Langerhans cell histiocytosis is uncommon and is said to indicate a poor prognosis. We describe a 2-year-old boy with onycholysis, subungual hyperkeratosis, and hemorrhages on his fingernails. He also had hepatosplenomegaly and pulmonary involvement. The diagnosis of Langerhans cell histiocytosis was made by histopathologic examination of skin and liver.The role of nail involvement as an unfavorable prognostic sign is still unclear and this paper concludes that nail involvement in Langerhans cell histiocytosis is a possible sign of multisystemic involvement.

RESUMEN

Oral mucoceles are common lesions characterized by accumulation of mucus following rupture of a minor salivary gland duct. However, congenital mucoceles are a rare and distinctive oral condition observed in newborns. This case report details the features of a congenital labial nodule diagnosed as congenital mucocele. These lesions are rare in the oral cavity and should be diagnosed in the delivery room, but many cases are referred for further evaluation. Management is simple, and recurrence is not expected.

RESUMEN

Lasers demonstrate excellent therapeutic action and are often employed in dentistry for the treatment of diverse clinical conditions. The aim of this study was to compare the efficacy of neodymium-doped yttrium-aluminum-garnet (Nd:YAG) laser, gallium-aluminum-arsenide (GaAlAs) laser, and 2% neutral fluoride gel in the treatment of dentinal hypersensitivity. Twenty-three patients were evaluated, involving a total of 48 quadrants with at least 1 tooth with dentinal hypersensitivity (89 teeth total). Pain intensity was recorded on a visual analog scale at the time of clinical examination (baseline), immediately after treatment, and 1 week posttreatment. Teeth were treated with 60 seconds of 2% neutral fluoride gel application or 60 seconds of laser treatment-Nd:YAG laser at a distance of 0.5 cm (unfocused; 1 W and 10 Hz for 60 seconds, perpendicular to the cervical surfaces) or GaAlAs laser in contact (40 mW; 4 J/cm²; spot: 0.028 cm²; 15 seconds per point on 4 points [mesial, medial, distal, and apical])-as well as sham treatments so that patients remained blind to their treatment group. All treatments provided adequate pain reduction immediately posttreatment, but laser treatments resulted in significantly greater reductions in pain intensity.
