Effect of multidrug solution for the treatment of chemotherapy-induced oral mucositis in vivo.

Objective: Evaluate the effect of a multidrug solution, adopted by a referral hospital for cancer to control and treat chemotherapy-induced oral mucositis in rats. Methods: Oral mucositis (OM) was induced by 5-Fluorouracil (5-FU), and the animals were treated with saline (n = 8, G1), 0.12% chlorhexidine (n = 8, G2); and multidrug solution (n = 8, G3). The animals were submitted to clinical and histological analysis of the lesion using mucosal fragments. The animals' food consumption during treatment was also evaluated. Results: Clinical improvement (p < 0.05) was observed in the groups treated with the multidrug solution and 0.12% chlorhexidine digluconate. In G2 and G3, there was a prevalence of reepithelialization covering <50% of the lesion. Evaluation of the inflammatory infiltrate indicated that the G1 treatment permitted an intense inflammatory response in all animals, yet this evaluation parameter was moderate in groups G2 and G3. The G3 group (p < 0.05) presented higher food consumption than the other groups. Conclusions: The multidrug solution improved the clinical and histological parameters of the chemotherapy-induced oral mucositis, as well as promoted an increase in food intake.

COVID-19 Pandemic Causes Increased Clinic Visits with Diagnosis of Tegumentary Leishmaniasis in Brazil in 2020.

Coronavirus disease 2019 (COVID-19) protocols has reduced primary and secondary health care for other diseases, such as leishmaniasis, a parasitic, endemic, chronic and persistent disease in Brazil. To ascertain this, we compared the number of leishmaniasis cases diagnosed before and after the COVID-19 pandemic. In 5 regions of Brazil, there was an increase in the mean number of leishmaniasis clinic visits from 2020 pandemic period (over 57%) compared with 2017-2019 years. Interestingly, this increase was due to tegumentary leishmaniasis (TL) while visceral leishmaniasis consultations decreased considerably. The increase in clinic visits with a diagnosis of TL in all regions of Brazil during the pandemic period in 2020, shows that the epidemiological surveillance of neglected tropical diseases cannot slowdown in the country. Expanding information can minimize the negative impacts of COVID-19 on health promotion, prevention and monitoring of the most prevalent neglected diseases.

The impact of the COVID-19 pandemic on undergraduate and graduate dental courses in Brazil.

BACKGROUND: The COVID-19 pandemic has raised challenges in adapting to teaching and learning methods in dental education. OBJECTIVE: This study aimed to evaluate the impact of the COVID-19 pandemic on the academic activities of undergraduate (UDG) and graduate (GD) dental students in Brazil. Additionally, students' perceptions and attitudes toward teaching activities during this period were analyzed. METHODS: A nationwide cross-sectional survey was conducted with a sample of Brazilian UDG and GD dentistry students. Data were collected in 2020 through an online, self-administered, and anonymous questionnaire, which comprised 26 questions related to demographic data, activities of the college, family and individual student income, and attitudes and perceptions about e-learning during the pandemic. The data were tabulated and analyzed using descriptive statistics. RESULTS: The sample included 1,166 students (779 UDG and 387 GD). Among these, 425 (54.6%) UDG and 270 (69.8%) GD students remotely participated in teaching activities, of which 42.6% of the UDG considered their performance in e-learning to be bad or very bad and 49.8% of the GD regarded it as good or excellent. The survey also showed that 354 (45.4%) UDG and 102 (26.4%) GD expressed a desire to discontinue the course following the outbreak of the pandemic. Among the GD, 225 (58.4%) said that their experiments were completely interrupted. CONCLUSIONS: This study reveals the poor perception and performance of dental students regarding e-learning. Additionally, the findings suggest a negative impact of the pandemic on dental education in Brazil. Effective measures should be taken to mitigate these significant consequences.

Case Report: Scabies Invading Gingival Tissue.

Non-plaque-induced lesions may occur on the gingiva as medical disorders or manifestations of systemic conditions. Scabies is a parasitic infection caused by Sarcoptes scabiei. Here, we present the first case of oral scabies reported in the literature located on the gingiva in a 43-year-old woman. She was admitted to the hospital complaining of an ulcerative lesion on the gingiva with unknown duration, with a suggestive diagnosis of pemphigoid. A diagnosis of scabies infestation was made based on the visualization of eggs and larvae/nymph forms. The treatment consisted of 100 mg of ivermectin (three times per day for 15 days), supplemental oral hygiene with chlorhexidine, and extensive cleaning. The follow-up was made 30 days after treatment with ivermectin. The patient did not report side effects, with skin and oral lesions completely healed. Based on this, we need to perform a thoughtful ectoscopy examination and be alert to signs that indicate unusual causes to diagnose correctly and choose the appropriate treatment.

Gingivoestomatitis herpética aguda en paciente adulto / Acute herpetic gingivostomatitis in adult patients

Introduction: Herpetic gingivostomatitis is an infection caused by herpes simplex virus, which affects mainly children patients, being uncommon this manifestation in adults. It initially appears with prodromal signs and then local signs show up. The treatment for this disease is only supportive, because there is already a peak of viral replication when it was diagnosed. Objectives: To report a case of herpetic gingivostomatitis and to discuss its clinical characteristics and treatment. Case report: The patient looked for clinic care for presenting painful oral lesions with little time of evolution. With no medical history, the patient reported using antibiotics and antifungals. Oroscopy showed multiple coalescing ulcerative lesions affecting the gum tissue, tongue, lips and hard palate. It has been diagnosed clinically as herpetic gingivostomatitis and has been treated with supportive treatment (analgesics, topical anesthetic and chlorhexidine digluconate 0,12 percent). The patient returned after one week with improvement of the condition. Conclusion: The correct diagnosis, through the evident clinical manifestations, prevents the indiscriminate use of antibiotics, leading to better response of the patient(AU)

Oral Mucositis in Pediatric Patients in Treatment for Acute Lymphoblastic Leukemia.

Oral mucositis in oncologic patients is the most undesirable event of the chemotherapeutic treatment. This study aimed to identify damage to the oral cavity resulting from chemotherapy in pediatric patients with acute lymphoblastic leukemia (ALL). This is a prospective study with a sample of 42 children and adolescents evaluated for 10 consecutive weeks after diagnosis. The modified Oral Assessment Guide (OAG) was used, and data were analyzed by Spearman's rank correlation coefficient (α = 5%). Changes to the normal lips and saliva were positively related to an increase in the OAG score during all 10 weeks of evaluation. Alterations to the labial mucosa were correlated with an increase in the OAG score from the 2nd to 10th week, which was also found for changes in the tongue and in the swallowing function in Weeks 1, 6, 8, 9, and 10 and for gum changes from the 5th to 7th week. No significant vocal changes were correlated with the total OAG score at any point during the monitoring period. Changes in lips, cheek and/or palatal mucosa, labial mucosa, and gum areas and in swallowing function were positively correlated with an increase in the severity of oral mucositis in patients with ALL after beginning chemotherapeutic treatment.

Monitoreo oral de un paciente pediátrico durante el tratamiento de quimioterapia / Oral monitoring of a pediatric patient during chemotherapy treatment

Oral side effects must be expected during cancer treatment on pediatric patients. Monitoring side effects on oral cavity of antineoplastic therapy is desirable but sometimes performed without criteria. The purpose of this article is to describe an oral monitoring in an male with Hodgkin lymphoma during chemotherapy treatment using an Oral Assessment Guide. An 11-yr-old male was assisted during all treatment of chemotherapy against Hodgkin's lymphoma in the dental sector of a hospital of reference of João Pessoa, Paraíba, Brazil. The Oral Assessment Guide was applied by a calibrate examiner and was observed the emergence of ulcerative lesions on the labial mucosa emerged on two different periods (D15- primary cycle; D15-second cycle) and the major values of oral mucositis were verified in D1 e D15 periods of second cycle of chemotherapy. Monitoring oral side effects during antineoplastic therapy could prevent severe oral complications and avoid to associate systemic complications(AU)

Los efectos secundarios orales se manifiestan durante el tratamiento del cáncer en los pacientes pediátricos. El monitoreo de los efectos secundarios en la cavidad oral de la terapia antineoplásica es deseable, pero a veces se realiza sin criterios. El propósito de este artículo es describir un monitoreo oral en un niño con linfoma de Hodgkin durante el tratamiento de quimioterapia, empleando una guía de evaluación oral. Un niño de 11 años de edad fue asistido durante todo el tratamiento de quimioterapia contra un linfoma de Hodgkin en el sector odontológico de un hospital de referencia de João Pessoa, Paraíba, Brasil.

Analysis of familial incidence of non-syndromic cleft lip and palate in a Brazilian population

Background: The purpose of this study is to follow the familial incidence of non-syndromic or isolated cleft lip,with or without cleft palate (NSCL/P), and to analyze the relation ships between the type of NSCL/P in the affected individual and his/her parent, looking at children in the first grade. Material and Methods: To investigate the familial incidence of NSCL/P we analyzed the records of 185 patients from 2004-2008, retrospectively. Detailed histories were collected regarding the familial incidence of NSCL/P.For the 185 individuals, the relationship between the type of NSCL/P and the sociodemographic and personal characteristics of the affected person and her/his cleft relatives was obtained. Results: The individuals were 42 carriers of CL, 109 with CLP (joined in one group) and 34 with CP (p<0.001).Of the total of participants, 65 (35.13%) presented a positive history of cleft in their families and 120 (64.86%)presented a negative history (p<0.001). There were differences between the cleft groups according to types ofcleft and positive familial history (p<0.001). In both groups, the relatives with higher incidence of NSCL/P were cousins, with the same pattern of distribution between the two groups (p=0.175).Conclusions: Most frequently, fissures result from CL/CLP with no familial history. However, CL/CLP was foundin familial cases and cousins were the relative type more likely to be affected (AU)

Neuroblastoma in an adult: Case report / Neuroblastoma en un adulto: Informe de un caso

El neuroblastoma es el tumor maligno sólido extracraneal más común en niños. Sólo el 10 por ciento de los casos se diagnostican después de la primera década de vida. Presentamos una paciente afroamericana de 23 años, con una masa paravertebral en T3-T5, múltiples lesiones en los cuerpos vertebrales y una lesión expansiva en la región parietal derecha. El estudio inmmunohistoquímico (negativo para CD99, CD20, CD3 y desmina y positivo para cromogranina, sinaptofisina y NB84), confirmó el diagnóstico de neuroblastoma. La paciente fue sometida a 12 ciclos de quimioterapia recibiendo VAC (vincristina / doxorubicina/ cyclofosfamida) intercalada con ICE (ifosfamida/ mesna/ etoposido). La doxorubicina fue reemplazada por actinomicina en el séptimo ciclo. La paciente toleró bien la quimioterapia y está clínicamente estable.

Neuroblastoma is the most common extracranial solid malignancy in children but rarely described in adults, being 10 percent of all cases diagnosed after the first decade of life. We report a 23 year-old black woman with a mass at paravertebral region of T3-T5, multiple lesions in vertebral bodies and expanding skull-brain lesion at the right parietal region. Immunohistochemical analysis (negative for CD99, CD20, CD3 and desmin; and positive chromogranin, synaptophysin and NB84) confi rmed the diagnosis of neuroblastoma. The patient was submitted to 12 cycles of chemotherapy receiving VAC (vincristine/doxorubicin/cyclophosphamide) interspersed with ICE (ifosfamide/mesna/etoposide) and doxorubicin was replaced by actinomycin in the 7th cycle. She had good tolerance to this therapy, and has been clinically stable.

Effectiveness of low flow vascular lesions sclerosis with monoetanolamine: Report of six cases

No disponible

Vascular malformations or even hemangiomas need therapeutic intervention if they start to cause clinical symptoms or personal discomfort. Different therapeutic modalities, including cryotherapy, corticosteroids, laser therapy, sclerotherapy, surgery, and/or embolization, can be performed successfully. Sclerotherapy with monoethanolamine is a relatively simple and effective method to treat low flow vascular lesions. We presented a report of six cases of vascular malformations treated with monoethanolamine. There were 3 male and 3 female patients, with an age range of 20 to 68 years. The patients were submitted to applications according to clinical response and/or tolerability. In all cases, low-flow vascular lesions were recorded and submitted to infiltration with 2.5% monoethanolamine, directly into the lesions. The volumeapplied was approximately the middle of affected area. Vascular lesions were characterized as low-flow due to absence of arterial pulsation and flat consistence. The sclerosis with 2.5% monoethanolamine resulted in complete or partial involution, without severe complications
