Anemia aplásica inducida por metimazol: presentación de caso / Methimazole Induced Aplastic Anemia: Case Report / Anemia aplástica induzida por metimazol: relato de caso

Introducción: los medicamentos antitiroideos son una de las alternativas terapéuticas en el tratamiento de la enfermedad de Graves. Sin embargo, pueden generar efectos adversos severos poco frecuentes en el plano hematológico, como la anemia aplásica, la cual se ha asociado con altas dosis de estos medicamentos, aunque con reversión de esta afección ante el retiro del medicamento. Descripción del caso: mujer de 38 años con antecedente de enfermedad de Graves en tratamiento con metimazol, quien consultó por síntomas como epistaxis anterior de difícil control, petequias, astenia e hiporexia. Se documentó pancitopenia en el hemo-grama, con posterior hallazgo en biopsia de médula ósea de aplasia medular, sin respuesta ante el retiro del metimazol y soporte transfusional. Posteriormente, la paciente falleció. Conclusión: la presentación de aplasia medular asociada con metimazol es poco común y se relaciona con altas dosis de este medicamento. En la mayoría de casos, el retiro de este agente genera recuperación clínica y celular. No obstante, en algu-nos pacientes persiste el compromiso hematológico que va desde importantes repercusiones clínicas hasta desenlaces fatales. Por lo tanto, el presente caso busca hace hincapié en la importancia de vigilar este efecto adverso ante el inicio de esta medicación

Introduction: Antithyroid drugs are one of the therapeutic alternatives in the treatment of Graves' dis-ease. However, it can generate severe but infrequent adverse effects at the hematological level, such as aplastic anemia, which has been associated with high doses of these drugs, although with reversal of this hematological condition when the drug is withdrawn. Case description: A 38-year-old woman with a his-tory of Graves' disease treated with methimazole, who consult for symptoms such as anterior epistaxis, petechiae, asthenia, and hyporexia. Pancytopenia is documented in the blood count, with a subsequent finding of bone marrow aplasia in bone marrow biopsy, without response to withdrawal of Methimazole and transfusion support. The patient subsequently died. Conclusion: The methimazole-associated bone marrow aplasia is uncommon and it ́s associated with high doses of methimazole, in most cases with-drawal of methimazole leads to clinical and cellular recovery. However, in some patients hematological involvement persists with significant clinical repercussions up to fatal outcomes. Therefore, this case seeks to highlight the importance of monitoring for this adverse effect before starting this medication

Introdução: as drogas antitireoidianas são uma das alternativas terapêuticas no tratamento da doença de Graves. No entanto, pode causar efeitos adversos graves, mas infrequentes, no nível hematológico, como a anemia aplástica, que tem sido associada a altas doses desses medicamentos, embora com rever-são desse quadro hematológico quando a droga é retirada. Descrição do caso: mulher de 38 anos com história de doença de Graves tratada com metimazol, que consultou por sintomas como epistaxe ante-rior de difícil controle, petéquias, astenia e hiporexia. A pancitopenia é documentada no hemograma, com achado posterior de aplasia da medula óssea na biópsia da medula óssea, sem resposta à retirada do metimazol e suporte transfusional. O doente faleceu posteriormente. Conclusão: a apresentação de aplasia da medula óssea associada ao metimazol é pouco frequente em associação com doses elevadas de metimazol. Na maioria dos casos, a retirada do metimazol conduz à recuperação clínica e celular. No entanto, nalguns doentes, o envolvimento hematológico persiste com repercussões clínicas significati-vas, podendo mesmo ocorrer desfechos fatais. Assim, o presente caso pretende realçar a importância da monitorização deste efeito adverso antes de iniciar esta medicação

Do oral antiseptics used in the dental routine have anti-viral efficacy? a systematic review of in vitro studies / Os antissépticos orais utilizados na rotina odontológica têm eficácia anti-viral? Uma revisão sistemática de estudos in vitro / ¿Los antisépticos orales utilizados en la rutina odontológica tienen eficacia antiviral? Una revisión sistemática de estudios in vitro

Introduction: Mouthwashes play an important role in the dental clinic, but their role on viruses requires investigation. Objective:to review in vitro studies to identify the effect of different mouthwashes on the main viruses associated with routine dental care. Methodology:The following databases were searched in September 2023: PubMed, Embase, Scopus and Web of Science databases; the Cochrane Library and the Virtual Health Library (VHL); and grey literature. In vitro studies that used mouthwashes to reduce the viral load were selected. The PICOS strategy was considered to define eligibility criteria: the Population (viruses involved in the etiology of oral infection), the Intervention (oral antiseptics), the appropriate comparator (positive and negative controls), the Outcomes of interest (reduction of viral load) and the Study design (in vitro studies). Results:Considering the eligibility criteria, 19 articles were included in this review. The efficacy of povidone-iodine (PVP-I), chlorhexidine, Listerine®, essential oils, and cetylpyridinium chloride (CPC) rinses were investigated. PVP-I (0.23%) had its effects mainly associated with coronaviruses SARS(Severe Acute Respiratory Syndrome),demonstrating a significant reduction in viral load after 15 seconds of exposure. Chlorhexidine (0.05%; 0.1% and 0.5%) was ineffective against adenovirus, poliovirus, and rhinovirus respiratory viruses. Listerine® demonstrated superior efficacy against HSV-1 and 2 viruses and influenza A, and cetylpyridine chloride also demonstrated virucidal activity against influenza A. Conclusions:The type, concentration, and time of exposure to antiseptics varied between studies. PVP-I and chlorhexidine digluconate were the most studied substances, butin general, PVP-I was more effective in reducing viral titers, especially concerning coronaviruses. Other antiseptics such as CPC, H2O2 and Listerine® have also shown significant reduction in viral load, but this is a limited number of studies (AU).

Introducción: El 50% de la población mundial usa tratamientos alternativos como productos herbarios. El 20% los consume de manera simultánea con algún tratamiento farmacológico para el control la Diabetes Mellitus tipo 2; enfermedad prevalente en adultos mayores. Es escasa la información acerca de las interacciones medicamentosas que pudieran producirse, siendo responsables de más de 7,000 muertes al año. Objetivo: Identificar los productos herbarios de mayor consumo del Adulto Mayor con Diabetes Mellitus Tipo 2, en Chapulco, Puebla, México y describir las posibles interacciones medicamentosas entre fármaco hipoglucemiante ­ producto herbario reportados en la literatura científica. Metodología: Estudio observacional, prolectivo, transversal, descriptivo, en una población de 35 adultos mayores diabéticos, con edad promedio de 70±7 años. Para la identificación de los productos herbarios de uso común y sus aplicaciones terapéuticas se aplicó el cuestionario U-PLANMED. Resultados: Se identificaron 50 productos herbarios y 18 combinaciones entre estos a la vez. El 40% de los participantes consumen simultáneamente más de dos productos herbarios con uno o dos fármacos hipoglucemiantes. Entre los productos de mayor consumo se encuentran el nopal (Opuntia ficus-indica L.), la manzanilla (Matricaria chamomilla L.) y el zacate de limón (Cymbopogon citratus DC. Stapf.). Las interacciones medicamentosas potenciales identificadas, principalmente en estudios experimentales en animales, sugieren que, existe una acción hipoglucemiante del producto herbario al aumentar la capacidad orgánica sobre la secreción/liberación de insulina endógena. Conclusiones: Se ha evidenciado la presencia de interacciones medicamentosas ante el consumo simultaneo de fármacos prescritos para el control de la diabetes mellitus tipo 2 con productos herbarios. Es necesario que, los profesionales en atención a la salud identifiquen el uso de dichos productos y orienten a los adultos mayores sobre las posibles repercusiones en los niveles de glucosa ante el consumo.

Introduction: 50% of the world's population uses alternative treatments such as herbal products. Twenty percent use them in conjunction with some form of pharmacological treatment to control type 2 diabetes mellitus, a disease prevalent in older adults. There is little information on the drug interactions that may occur, which are responsible for more than 7,000 deaths per year. Objective: To identify the most consumed herbal products among older adults with type 2 diabetes mellitus in Chapulco, Puebla, Mexico, and to describe the possible drug-drug interactions between hypoglycemic drugs and herbal products reported in the scientific literature. Methodology: Observational, prospective, cross-sectional, descriptive study in a population of 35 diabetic older adults with a mean age of 70±7 years. The U-PLANMED questionnaire was used to identify commonly used herbal products and their therapeutic applications. Results: Fifty herbal products and 18 combinations of them were identified. Forty percent of the participants used more than two herbal products simultaneously with one or two hypoglycemic drugs. The most used products included prickly pear cactus (Opuntia ficus-indica L.), chamomile (Matricaria chamomilla L.), and lemon grass (Cymbopogon citratus DC. Stapf.). Potential drug-drug interactions identified mainly in experimental animal studies suggest that there is a hypoglycemic effect of the herbal product by increasing the organic capacity on endogenous insulin secretion/release. Conclusions: The presence of drug-drug interactions has been demonstrated with the simultaneous consumption of drugs prescribed for the control of type 2 diabetes mellitus with herbal products. It is necessary for health care professionals to recognize the use of such products and to inform older adults about the possible repercussions on glucose levels when consuming them.

Introdução: 50% da população mundial utiliza tratamentos alternativos como os produtos à base de plantas. Vinte por cento utilizam-nos em conjunto com algum tipo de tratamento farmacológico para controlar a diabetes mellitus tipo 2, uma doença prevalente em adultos mais velhos. Há pouca informação sobre as interacções medicamentosas que podem ocorrer e que são responsáveis por mais de 7.000 mortes por ano. Objetivos: Identificar os produtos fitoterápicos mais consumidos entre os idosos com diabetes mellitus tipo 2 em Chapulco, Puebla, México, e descrever as possíveis interações medicamentosas entre medicamentos hipoglicemiantes e produtos fitoterápicos relatados na literatura científica. Metodologia: Estudo observacional, prospetivo, transversal e descritivo numa população de 35 idosos diabéticos com uma idade média de 70±7 anos. O questionário U-PLANMED foi utilizado para identificar os produtos fitoterápicos mais utilizados e suas aplicações terapêuticas. Resultados: Foram identificados 50 produtos à base de plantas e 18 combinações dos mesmos. Quarenta por cento dos participantes utilizaram mais de dois produtos à base de plantas em simultâneo com um ou dois medicamentos hipoglicemiantes. Os produtos mais utilizados foram o cato de figo da Índia (Opuntia ficus-indica L.), a camomila (Matricaria chamomilla L.) e o capim-limão (Cymbopogon citratus DC. Stapf.). As potenciais interacções medicamentosas identificadas principalmente em estudos experimentais em animais sugerem que existe um efeito hipoglicémico do produto à base de plantas através do aumento da capacidade orgânica na secreção/libertação de insulina endógena. Conclusões: A presença de interacções medicamentosas foi demonstrada com o consumo simultâneo de medicamentos prescritos para o controlo da diabetes mellitus tipo 2 com produtos à base de plantas. É necessário que os profissionais de saúde reconheçam o uso de tais produtos e informem os idosos sobre as possíveis repercussões nos níveis de glicose ao consumi-los.

Evaluation of unilateral corneal collagen cross-linking on fellow untreated eyes of patients with keratoconus / A avaliação da reticulação unilateral do colágeno corneano em olhos não tratados de pacientes com ceratocone

ABSTRACT Purpose: This study aimed to examine the effects of unilateral corneal collagen cross-linking treatment on visual acuity and the topographic findings of the fellow untreated eye of patients who had bilateral progressive keratoconus. Methods: Patients with progressive keratoconus who underwent cross-linking treatment were screened retrospectively. A total of 188 untreated eyes of 188 patients whose eyes were treated unilaterally with either standard or accelerated cross-linking and refused cross-linking procedure for the fellow eye were included. Visual acuity and topographic findings of the fellow untreated eyes were obtained preoperatively and postoperatively at the 1st, 3rd, 6th, 12th, 24th, 30th, and 36th months. Results: The change over time of variables examined was similar in the untreated eyes of patients who received standard and accelerated cross-linking methods (p>0.05). At the 12th month, 136 (95.8%) untreated eyes were stable according to progression criteria. Only 4 (8%) eyes were progressive at the 24th month. No progression was observed in any of the 16 patients with a 36-month follow up. Conclusions: The results showed that the fellow untreated eyes of patients with bilateral progressive keratoconus did not have significant progression rates after unilateral cross-linking treatment.

RESUMO Objetivo: Examinar os efeitos do tratamento de reticulação unilateral do colágeno corneano na acuidade visual e os achados topográficos em olhos não tratados de pacientes com ceratocone progressivo bilateral. Métodos: Foram rastreados retrospectivamente pacientes com ceratocone progressivo submetidos a tratamento de reticulação. Foram incluídos no estudo 188 olhos não tratados de 188 pacientes tratado unilateralmente com reticulação padrão ou acelerada e que recusaram o procedimento de reticulação no outro olho. A acuidade visual e os achados topográficos dos olhos não tratados foram obtidos no pré- e pós-operatório no 1º, 3º, 6º, 12º, 24º, 30º e 36º mês. Resultados: As alterações ao longo do tempo foram semelhantes para as variáveis examinadas nos olhos não tratados de pacientes tratados com métodos de reticulação padrão e acelerado (p>0,05). No 12º mês, 136 olhos não tratados (95,8%) estavam estáveis, de acordo com os critérios de progressão. Apenas quatro olhos (8%) mostraram progressão no 24º mês. Nenhuma progressão foi observada nos 16 pacientes que tiveram um acompanhamento de 36 meses. Conclusões: O estudo mostrou que os olhos não tratados de pacientes com ceratocone progressivo bilateral não apresentaram taxas de progressão significativas após o tratamento unilateral com reticulação.

Effect of Ceramic Thickness on the Bond Strength to Resin-Luting Agents before and after Thermal Cycling

Abstract This study investigated microshear bond strength (µSBS) of two (2) dual-cured resin-luting agents (RelyX™ Ultimate and RelyX™ U200) when photoactivated through varying thicknesses of lithium disilicate, with or without thermal cycling. Discs of IPS e.max Press of 0.5, 1.5, and 2 mm in thickness were obtained. Elastomer molds (3.0 mm in thickness) with four cylinder-shaped orifices 1.0 mm in diameter, were placed onto the ceramic surfaces and filled with resin-luting agents. A Mylar strip, glass plate, and load of 250 grams were placed over the filled mold. The load was removed and the resin-luting agents were photoactivated through the ceramics using a single-peak LED (Radii Plus.) All samples were stored in distilled water at 37oC for 24 h. Half of the samples were subjected to thermal cycling (3,000 cycles; 5ºC and 55ºC). All samples were then submitted to µSBS test using a universal testing machine (Instron 4411) at a crosshead speed of 0.5 mm/min. Data were submitted to three-way ANOVA and Tukey post-hoc test (α=0.05). The mean µSBS at 24 h was significantly higher than after thermal cycling (p<0.05). No statistical difference was found between resin-luting agents (p > 0.05). The mean µSBS for groups photoactivated through 0.5 mm ceramic were significantly higher than 1.5 mm and 2.0 mm (p < 0.05). In conclusion, increased ceramic thicknesses reduced the bond strength of tested resin-luting agents to lithium disilicate. No differences were found between resin-luting agents. Thermal cycling reduced the bond strength of both resin-luting agents.

Resumo: Este estudo investigou a resistência de união ao microcisalhamento (RUµC) de dois (2) agentes de cimentação de resina dual (RelyX™ Ultimate e RelyX™ U200) quando fotoativados através de diferentes espessuras de dissilicato de lítio, com ou sem ciclagem térmica. Discos do IPS e.max Press de 0,5, 1,5 e 2 mm de espessura foram obtidos. Moldes de elastômero (3,0 mm de espessura) com quatro orifícios cilíndricos de 1,0 mm de diâmetro foram colocados sobre as superfícies cerâmicas e preenchidos com agentes de cimentação de resina. Uma tira Mylar, placa de vidro e carga de 250 gramas foram colocadas sobre o molde preenchido. A carga foi removida e os agentes de cimentação resinosos foram fotoativados através da cerâmica usando um LED de pico-único (Radii Plus). Todas as amostras foram armazenadas em água deionizada a 37oC por 24 h. Metade das amostras foi submetida a ciclagem térmica (3.000 ciclos; 5ºC e 55ºC). Todas as amostras foram então submetidas ao teste de RUµC usando uma máquina de teste universal (Instron 4411) com velocidade de 0,5 mm/min. Os dados foram submetidos à Análise de Variância três fatores e ao teste post-hoc de Tukey (α = 0,05). A média de RUµC em 24 h foi significativamente maior do que após a ciclagem térmica (p < 0,05). Não houve diferença estatística entre os cimentos resinosos (p > 0,05). As médias de RUµC para grupos fotoativados através de cerâmica de 0,5 mm foram significativamente maiores do que 1,5 mm e 2,0 mm (p < 0,05). Em conclusão, o aumento da espessura da cerâmica reduziu a resistência de união dos agentes de cimentação resinosos ao dissilicato de lítio. Não foram encontradas diferenças entre os agentes de cimentação resinosos. A ciclagem térmica reduziu a resistência de união de ambos os agentes de cimentação resinosos.

In-office dental bleaching in adolescents using 6% hydrogen peroxide with and without gingival barrier: a randomized double-blind clinical trial

Abstract At low concentrations used for in-office bleaching gels, such as 6% HP, gingival barrier continues to be performed. If we take into account that, in the at-home bleaching technique, no barrier is indicated, it seems that the use of a gingival barrier fails to make much sense when bleaching gel in low concentration is used for in-office bleaching. Objective This double-blind, split-mouth, randomized clinical trial evaluated the gingival irritation (GI) of in-office bleaching using 6% hydrogen peroxide (HP) with and without a gingival barrier in adolescents, as well as color change and the impact of oral condition on quality of life. Methodology Overall, 60 participants were randomized into which side would or would not receive the gingival barrier. In-office bleaching was performed for 50 minutes with 6% HP in three sessions. The absolute risk and intensity of GI were assessed with a visual analogue scale. Color change was assessed using a digital spectrophotometer and color guides. The impact of oral condition on quality of life was assessed using the Brazilian version of the Oral Health Impact Profile (α=0.05). Results The proportion of patients who presented GI for the "with barrier" group was 31.6% and for the "without barrier" group, 30% (p=1.0). There is an equivalence for the evaluated groups regarding GI intensity (p<0.01). Color change was detected with no statistical differences (p>0.29). There was a significant impact of oral condition on quality of life after bleaching (p<0.001). Conclusions The use or not of the gingival barrier for in-office bleaching with 6% HP was equivalent for GI, as well as for bleaching efficacy, with improvement in the impact of oral condition on quality of life.

Color and surface roughness alterations of bulk-fill resin composites submitted to simulated toothbrushing with whitening dentifrices

Aim: To evaluate the surface roughness and color stability of bulk-fill resin composites after simulated toothbrushing with whitening dentifrices. The radioactive/relative dentin abrasion (RDA) and radioactive/relative enamel abrasion (REA) of dentifrices were also assessed. Methods: Specimens (n=10) of Tetric N Ceram Bulk Fill (TNCB), Filtek One Bulk Fill (FOB) resin composites, and Z100(Control) were prepared using a cylindrical Teflon matrix. Surface roughness (Ra, µm) was assessed by a roughness meter and the color evaluations (ΔEab , ΔE00 , WID ) were performed using a digital spectrophotometer based on the CIELAB system. Three measurements were performed per sample, before and after simulated toothbrushing with 3D Oral-B White Perfection (3DW) and Black is White (BW) dentifrices. The abrasivity (REA and RDA values) of the used dentifrices was also determined by the Hefferren abrasivity test. Results: The Ra values increased significantly in all resin composites after 3DW and BW toothbrushing. The acceptable threshold color varied among resin composites, and TNCB and Z100 presented the highest ΔEab and ΔE00 for BW dentifrice. The 3DW dentifrice was significantly more abrasive than BW dentifrice on enamel and dentin. Conclusions: simulated toothbrushing with tested whitening dentifrices increased the surface roughness at acceptable levels. The Tetric N Ceram Bulk-fill and Z100 composite showed the highest color alteration in BW. 3D White Perfection dentifrice was more abrasive on dentin and enamel than Black is White.

Contraindicated use of modern contraceptives among mothers from a Pelotas Birth Cohort

ABSTRACT OBJECTIVE To describe the prevalence of contraindicated use of combined hormonal contraceptives, progesterone-only contraceptives, and intrauterine devices in mothers participating in the 2015 Pelotas Birth Cohort according to the WHO medical eligibility criteria. METHODS The biological mothers of children belonging to the 2015 Pelotas birth cohort who attended the 48-month follow-up were studied. The 48-month follow-up data were collected from January 1, 2019, to December 31, 2019. Contraindicated use of modern contraceptives was considered to occur when these women presented at least one of the contraindications for the use of modern contraceptives and were using these methods. The prevalence of contraindicated use was calculated according to each independent variable and their respective 95% confidence intervals (95%CI). RESULTS The analyzed sample consisted of 3,053 women who used any modern contraceptive method. The prevalence of contraindicated use of modern contraceptives totaled 25.9% (95%CI: 24.4-27.5). Combined hormonal contraceptives showed the highest prevalence of contraindicated use (52.1%; 95%CI: 49.3-54.8). The prevalence of contraindicated use of modern contraceptives methods was greater in women with family income between one and three minimum wages, a 25-30 kg/m2 body mass index, indication by a gynecologist for the used method, and purchasing the contraceptive method at a pharmacy. The higher the women's education, the lower the prevalence of inappropriate use of modern contraceptives. CONCLUSION In total, one in four women used modern contraceptives despite showing at least one contraindication. Policies regarding women's reproductive health should be strengthened.

When the fever will not stop, stop the pills! A case report

ABSTRACT Neuroleptic malignant syndrome (NMS) is a neurologic emergency potentially fatal. This rare side effect is most commonly associated with first-generation antipsychotics and less frequently with atypical or second-generation antipsychotics. The diagnosis relies on both clinical and laboratory criteria, with other organic and psychiatric conditions being ruled out. CASE REPORT: A 39-year-old female patient, who is institutionalized and completely dependent, has a medical history of recurrent urinary infections and colonization by carbapenem-resistant Klebsiella pneumoniae. Her regular medication regimen included sertraline, valproic acid, quetiapine, risperidone, lorazepam, diazepam, haloperidol, baclofen, and fentanyl. The patient began experiencing dyspnea. Upon physical examination, she exhibited hypotension and a diminished vesicular murmur at the right base during pulmonary auscultation. Initially, after hospitalization, she developed high febrile peaks associated with hemodynamic instability, prompting the initiation of antibiotic treatment. Despite this, her fever persisted without an increase in blood inflammatory parameters, and she developed purulent sputum, necessitating antibiotherapy escalation. The seventh day of hospitalization showed no improvement in symptoms, suggesting NNMS as a differential diagnosis. All antipsychotic and sedative drugs, as well as antibiotherapy, were discontinued, after which the patient showed significant clinical improvement. CONCLUSION: Antipsychotic agents are commonly employed to manage behavioral changes linked to various disorders. However, their severe side effects necessitate a high degree of vigilance, the cessation of all medications, and the implementation of supportive care measures. A prompt and accurate diagnosis of NMS is crucial to alleviating the severe, prolonged morbidity and potential mortality associated with this syndrome.

Microbiological profile and antibiotic sensitivity of maxillofacial infections in an emergency hospital

Aim: To investigate the bacteriological profile of oral and maxillofacial infections and the pattern of sensitivity to a specific group of antibiotics in a reference emergency hospital in Brazil. Methods: This is a prospective cohort institutional study that studied patients affected by oral and/ or maxillofacial infections in a Brazilian emergency hospital, over a 12-month period, of different etiologies, through data collection, culture and antibiogram tests, and monitoring of the process of resolution of the infectious condition. The variables were analyzed using the chi-square and Mann-Whitney tests, using a significance level of 5%. Results: The sample consisted of 61 patients, 62.3% male. The mean age of participants was 34.3 years. Odontogenic infection was the most frequent etiology and the submandibular space was the most affected. The bacterial species Streptococcus viridans was isolated in 21.6% of cases. Levofloxacin, vancomycin and penicillin were the antibiotics with the highest frequency of bacterial sensitivity, while clindamycin and erythromycin showed the highest percentages of resistance. Conclusions: The results suggest that, among the most used antibiotics for the treatment of these infections, penicillin remains an excellent option of choice for empirical therapy

The impact of synthetic bone grafting for tissue regeneration: an in vivo study

Aims: This study aimed to examine the biological response of synthetic nanocomposite material on canine mandibular bone. Methods: Nine healthy adult male local breed dogs aged 12 to 18 months and weighing 10.2 to 15.2 kg were used in the study. Based on healing intervals of 1 and 2 months, the dogs were divided into 2 groups. Each group had 3 subgroups with 3 dogs each. The division was based on the grafting material used to fill the created defect: an empty defect (Control-ve), Beta-Tricalcium Phosphate, and nanocomposite (Beta-Tricalcium Phosphate and nanosilver 1%) . Surgery started after the dogs were anaesthetized. The surgical procedure began with a 5 cm parallel incision along the mandible's lower posterior border. After exposing the periosteum, a three 5mm-diameter, 5-mmdeep critical-size holes were made, 5mm between each one. Each group's grafting material had independent 3 holes. The defects were covered with resorbable collagen membranes followed by suturing of the mucoperiosteal flap. Results: Total densitometric analysis showed no significant differences between groups at 1-month intervals, with the nanocomposite group having a higher mean rank (165.66± 31.21) in comparison to other groups while at 2 months intervals that there was a highly significant difference between three groups as the P-value was (0.000) with the nanocomposite group having a higher mean rank (460.66± 26.40). Conclusions: In the current study, the use of nanocomposites improved osteoconductivity by accelerating new bone formation. Moreover, the encorporation of nanosilver enhanced growth factor activity. These attributes make nanocomposites a promising material for enhancing the bone healing process

Antibiotics prophylaxis at the time of catheter removal after radical prostatectomy: a systematic review of the literature and meta-analysis

Purpose: To conduct a systematic literature review with meta-analysis to identify whether antibiotic prophylaxis after removal of the indwelling urinary catheter reduces posterior infections. Methods: A systematic literature review was conducted in the databases PubMed, Embase, Cochrane, Google Scholar, and Latin American and Caribbean Health Sciences Literature, using the keywords "antibiotics" AND "prostatectomy" AND "urinary catheter." Results: Three articles were identified having the scope of our review, with 1,040 patients, which were subjected to our meta-analysis revealing a marginally significant decrease in the risk of urinary infection after indwelling urinary catheter removal (odds ratio-OR = 0.51; 95% confidence interval-95%CI 0.27-0.98; p = 0.04; I2 = 0%). No difference was found regarding the presence of bacteriuria (OR = 0.39; 95%CI 0.12-1.24; p = 0.11; I2 = 73%). Conclusions: In our meta-analysis, there was a significant decrease in urinary tract infection with antibiotic prophylaxis after indwelling urinary catheter removal following radical prostatectomy.

Firework-related ocular trauma in Pernambuco, Brazil / Trauma ocular por fogos de artifício em Pernambuco, Brasil

ABSTRACT Purpose: This study aimed to describe the demographic and clinical characteristics of victims of fireworkrelated ocular trauma treated at the ophthalmologic emergency de partments of two reference centers in Pernambuco, Brazil, and to identify risk factors related to poor visual prognosis. Methods: We retrospectively evaluated the medical records of patients admitted in emergency departments with a report of firework-related trauma between January 2012 and December 2018. Data collected included patient's age, sex, place of origin, month and year of the accident, ocular structures affected, characteristics of the injuries, and type of treatment that patients received. For patients who were followed for >30 days, the final visual acuity and patient's origin were analyzed. Results: Three hundred and seventy eyes from 314 patients were included, of which 248 (79.0%) were male and 160 (51.0%) were from the metropolitan region of Recife. The mean patient age was 25.6 ± 18.8 years. In 56 (17.8%) patients, the ocular trauma was bilateral. A total of 152 (48.4%) cases occurred in June. The most affected sites were the eyelids in 91 (24.6%) eyes and ocular surface in 252 (68.1%). Surgical treatment was required in 87 (23.5%) eyes. After clinical and surgical management, 37 (10.0%) eyes presented final visual acuity of <20/400. Of these, 34 (91.9%) eyes were from patients from the countryside or from another state. Patients from the countryside presented higher risk of developing blindness after a firework trauma than those from the metropolitan area (odds ratio of 5.46). Conclusions: Victims of firework-related ocular trauma were mostly male, from the metropolitan region of Pernambuco state and mainly pediatric patients or economically active. Those coming from the countryside and other states had higher risk of developing blindness

A coleta de dados incluiu idade, gênero, procedência, mês e ano do acidente, estruturas oculares acometidas e características das lesões, além do tipo de tratamento a que os pacientes foram submetidos. Naqueles pacientes acompanhados por mais de 30 dias, analisou-se a acuidade visual final e a associação com sua procedência. Resultados: Foram incluídos 370 olhos de 314 pacientes. Destes, 248 (79,0%) vítimas eram do sexo masculino e 160 (51,0%) da região metropolitana do Recife, com uma média de idade de 25.6 ± 18.8 anos. Em 56 (17,8%) dos casos o trauma foi bilateral. No mês de junho ocorreu um total de 152 (48,4%) casos. Os sítios mais acometidos foram pálpebras em 91 (24,6%) olhos e superfície ocular em 252 (68,1%). O tratamento cirúrgico foi necessário em 87 (23,5%) olhos. Após manejo clínico-cirúrgico, 37 (10.0%) olhos desenvolveram visão pior do que 20/400. Destes, 34 (91,9%) olhos eram de pacientes do interior do estado de Pernambuco ou de outro estado. Os pacientes provenientes do interior do estado apresentaram maior chance de desenvolver cegueira quando comparados aos que eram provenientes da região metropolitana (Odds Ratio de 5,46). Conclusões: As vítimas de trauma ocular por fogos de artificio foram em sua maioria do sexo masculino, procedentes da região metropolitana do estado e das faixas etárias pediátrica e economicamente ativa. Aqueles provenientes do interior ou de outros estados apresentaram maior chance de desenvolver cegueira.

Cytotoxicity evaluation, antibacterial effect, and degree of conversion of QAM-containing adhesives

Abstract The aim of this study was to evaluate the influence of adding quaternary ammonium methacrylates (QAMs) to experimental adhesives by assessing the degree of conversion (DC), cytotoxicity against keratinocytes and fibroblasts, and antibacterial activity against biofilm formation. Two QAMs were added to an experimental adhesive: dimethylaminododecyl methacrylate bromododecane (DMADDM) or dimethylaminododecyl methacrylate bromohexadecane (DMAHDM) at three concentrations each: 1, 2.5, and 5 wt.%. Experimental adhesive without QAMs (control group) and commercially available Transbond XT Primer (3M Unitek, Monrovia, California, USA) were used for comparisons. The adhesives were tested for DC, cytotoxicity against keratinocytes and fibroblasts, and antibacterial activity against biofilm formation. DC, cytotoxicity against fibroblasts, and antibacterial activity were analyzed using one-way ANOVA and Tukey's multiple comparisons. Cytotoxicity against keratinocytes was evaluated using the Kruskal Wallis and Dunn's post-hoc (α = 5%) tests. Transbond showed lower DC as compared to 5% DMAHDM, 1% DMADDM, and 5% DMADDM (p < 0.05). However, all groups presented proper DC when compared to commercial adhesives in the literature. In the evaluation of cytotoxicity against keratinocytes, Transbond induced higher viability than 2.5 wt.% groups (p < 0.05). Against fibroblasts, Transbond induced higher viability as compared to 5 wt.% groups (p < 0.05). DMAHDM at 5 wt.% reduced biofilm formation when compared to all the other groups (p < 0.05). Despite their cytotoxic effect against keratinocytes, gingival fibroblasts showed higher viability. DMAHDM at 5 wt.% decreased Streptococcus mutans viability. The incorporation of DMAHDM at 5 wt.% may be a strategy for reducing the development of white spot lesions.

Garlic Extract Reverses Ischemic Heart Disease in Female Rats Exposed to Combined Oral Contraceptive Pills

Abstract Background Garlic is an herbal medicinal plant with several pharmacological properties used for the management of various ailments. However, its potential in the reversal of ischemic heart disease induced by combined oral contraceptive pills is not well reported. Objective This study investigated the cardioprotective potential of aqueous garlic extract against cardiotoxicity induced by oral contraceptive pills. Methods Forty-six rats were used for this study. Six were used to determine the lethal dose (LD50), and 40 rats were divided randomly into 5 groups of 8 rats each. Group A received feed and distilled water. Group B received 0.6 mg/kg of oral contraceptive pills. Group C received 500 mg/kg of garlic extract. Group D received 0.6 mg/kg of oral contraceptive pills + 500 mg/kg garlic extract. Group E received 0.6 mg/kg of oral contraceptive pills + 700 mg/kg garlic extract. The animals were sacrificed, and blood and tissue samples were collected for biochemical and histological analysis. Statistical analysis was done using SPSS, and p values < 0.05 were considered significant. Results The acute toxicity dose of combined oral contraceptive pills was 1.5 mg/kg for albino rats. Combined oral contraceptive pills induced ischemic necrosis as revealed by the photomicrographs, in addition to elevation of serum cardiac troponin-1, lactate dehydrogenase, creatine kinase, and malondialdehyde levels. Treatment with garlic extract demonstrated significant reduction in cardiac troponin-1 (p = 0.000), lactate dehydrogenase (p = 0.002), creatine kinase (p = 0.001), and malondialdehyde (p = 0.001) levels, as well as restoration of the cardiac cytoarchitecture changes caused by the combined oral contraceptive pills. Conclusion This study has demonstrated that aqueous garlic juice can reverse ischemic heart disease, lessen cytoarchitectural alterations of the heart caused by combined oral contraceptive pills, and thus ameliorate cardiac dysfunction.

After 24 hours, the Persea americanaextract showed the biofilm at 90%, followed by Cynara scolymus, which interrupted it at 85%, There was a change in proteinase intensity after 5 minutes and 24 hours. with an average enzymatic activity of 0.69 compared to the control of 0.49. Cynara scolymus was the extract with the highest mean concentration of 100 mg/ml; the phospholipase intensity was changed with Stryphnodendron barbatiman being more effective in 24 hours compared to the control (p< 0.0001). The hemolysin secretion was modified by Hamamelis virginiana (12.5 mg/ml) after 5 minutes of exposure, and in 24 hours. all extracts were capable to cause changes in secretion. Conclusion: The tested extracts have antifungal potential in Candida albicans biofilms, implying a significant reduction in virulence factors. Thus, these can be indicated as an alternative therapeutic tool to reduce the morbidity of these infections, as in both investigated exposure times. they were able to reduce theenzymatic secretion of the fungus (AU)

Overprescription of short-acting β2 agonists: reflections from the SABINA study in Brazil / Prescrição excessiva de β2-agonistas de curta duração: reflexões a partir do estudo SABINA no Brasil

ABSTRACT Objective: To assess prescription patterns for short-acting b2 agonists (SABAs) and other asthma medications in asthma patients treated by specialists and participating in the SABA use IN Asthma (SABINA) study in Brazil. Methods: This was an observational, cross-sectional study conducted at five sites in different regions of Brazil. The primary endpoints were to record SABA prescriptions and obtain data on over-the-counter (OTC) SABA purchases at the pharmacy. Results: Data on 218 asthma patients were analyzed. Of those 218 patients, 80.3% were prescribed SABAs in addition to their maintenance therapy, with a mean of 11.2 SABA canisters in the previous 12 months. Of those patients, 71.4% were prescribed ≥ 3 canisters and 42.2% were prescribed ≥ 10 canisters. None of the patients were prescribed SABA monotherapy. A total of 14.2% of the patients reported purchasing SABAs OTC at a pharmacy without a prescription. Of those, 48.4% purchased ≥ 3 SABA canisters. A fixed-dose combination of an inhaled corticosteroid and a long-acting b2 agonist was prescribed to 95.0% of the patients. In the year before the study visit, 45.0% of the patients received at least one course of oral corticosteroid burst treatment. Asthma was well controlled in 43.1% of the patients, partly controlled in 34.9%, and uncontrolled in 22.0%. Patients reported a mean of 1.1 severe asthma exacerbations, with 49.1% experiencing 1 or more severe exacerbations. Conclusions: Overprescription and OTC purchases of SABAs are common in Brazil, possibly leading to the need for courses of oral corticosteroids. The health care community should collaborate to implement evidence-based recommendations and promote health education to improve asthma management in Brazil.

RESUMO Objetivo: Avaliar os padrões de prescrição de short-acting b2 agonists (SABAs, b2-agonistas de curta duração) e outros medicamentos para asma em pacientes tratados por especialistas e participantes do estudo SABA use IN Asthma (SABINA) no Brasil. Métodos: Trata-se de um estudo transversal observacional realizado em cinco locais em diferentes regiões do Brasil. Os desfechos primários foram registrar as prescrições de SABAs e obter dados a respeito da compra de SABAs sem receita médica na farmácia. Resultados: Foram analisados dados a respeito de 218 pacientes com asma. Dos 218 pacientes, 80,3% receberam prescrição de SABA além da terapia de manutenção, com uma média de 11,2 frascos de SABA nos 12 meses anteriores. Destes, 71,4% receberam prescrição de ≥ 3 frascos e 42,2% receberam prescrição de ≥ 10 frascos. Nenhum dos pacientes recebeu prescrição de monoterapia com SABA. Do total de pacientes, 14,2% relataram que compraram SABAs sem receita médica na farmácia. Destes, 48,4% compraram ≥ 3 frascos de SABA. Foram prescritas doses fixas combinadas de corticosteroide inalatório e b2-agonista de longa duração para 95,0% dos pacientes. No ano anterior à visita do estudo, 45,0% dos pacientes receberam pelo menos um ciclo de tratamento de curta duração com corticosteroide oral. A asma estava bem controlada em 43,1% dos pacientes, parcialmente controlada em 34,9% e não controlada em 22,0%. Os pacientes relataram uma média de 1,1 exacerbações graves da asma, sendo que 49,1% apresentaram uma ou mais exacerbações graves. Conclusões: A prescrição excessiva e a compra de SABAs sem receita médica são comuns no Brasil e possivelmente levam à necessidade de uso de corticosteroides orais. A comunidade de profissionais de saúde deve colaborar para implantar recomendações baseadas em evidências e promover a educação em saúde para melhorar o manejo da asma no Brasil.
