Radical surgical approach to chronic suppurative osteomyelitis: Case report / Abordaje quirúrgico radical de una osteomielitis crónica supurativa: reporte de caso

Abstract Diabetes mellitus is a systemic condition potentially related to an increased risk of progression of various infections such as chronic osteomyelitis by accelerating the inflammatory process with bone tissue necrosis and suppuration. Therefore, if there is no proper management of these infections, they can be life-threatening as they spread to deeper spaces in the head and neck. We describe the case of a 52-year-old male patient with a history of diabetes mellitus and grade III osteoarthritis who was diagnosed with chronic suppurative osteomyelitis of the mandible. He underwent a multidisciplinary surgical intervention in which he underwent a hemimandibulectomy with immediate mandibular reconstruction. The present case highlights the importance of early and radical treatment of patients with chronic suppurative osteomyelitis of the mandible and systemic comorbidities. In addition, this case presents a review of diabetes mellitus and the risk of developing odontogenic infections and complications when invading deeper spaces in the head and neck. Therefore, in this population, careful planning is required for early surgical and pharmacological treatment.

Resumen La diabetes mellitus es una condición sistémica potencialmente relacionada con un mayor riesgo de progresión de diversas infecciones como la osteomielitis crónica al acelerar el proceso inflamatorio con necrosis del tejido óseo y supuración. Por lo tanto, si no hay un manejo adecuado de estas infecciones pueden ser potencialmente mortales al llegar a propagarse a espacios más profundos de la cabeza y cuello. Describimos el caso de un paciente varón de 52 años con antecedentes de diabetes mellitus y osteoartrosis grado III a quien se le diagnosticó de osteomielitis crónica supurativa mandibular. Se le realizó una intervención quirúrgica multidisciplinaria en la cual se le realizó una hemimandibulectomía con reconstrucción mandibular inmediata. El presente caso destaca la importancia del tratamiento temprano y radical de los pacientes con osteomielitis mandibular crónica supurativa y comorbilidades sistémicas. Además, en este caso se presenta una revisión sobre la diabetes mellitus y el riesgo de desarrollar infecciones odontogénicas y complicaciones al invadir espacios más profundos de la cabeza y cuello. Por lo tanto, en esta población se requiere de una planificación cuidadosa para realizar un tratamiento quirúrgico y farmacológico temprano.

Alteraciones genéticas asociadas a la enfermedad de Parkinson y Alzheimer: evolución y respuesta al tratamiento / Genetic Alterations Associated with Parkinson's and Alzheimer's Disease: Evolution and Response to Treatment

La enfermedad de Parkinson y Alzheimer son las enfermedades neurodegenerativas más frecuentes a nivel mundial. Tienen etiología multifactorial, entre ellas, la genética; y son motivo de interés en la investigación científica actual. Se realizó una revisión narrativa con el objetivo de determinar las alteraciones genéticas asociadas a estas patologías, además su influencia en la evolución y respuesta al tratamiento de ellas. Se consultaron artículos originales, revisiones bibliográficas, sistemáticas, metaanálisis en inglés y español, con fecha de publicación entre el 1 enero de 2018 y el 20 de mayo de 2023, en bases como PubMed y Medline. Se utilizaron los términos MeSH «Alzheimer Disease¼, «Parkinson Disease¼, «Drug Therapy¼ y «Mutations¼. El riesgo hereditario para la enfermedad de Parkinson suele ser poligenético, sin embargo, existen genes relacionados con mutaciones monogénicas. Se identifican alteraciones en genes de α-sinucleína, glucocerebrosidasa y quinasa 2 rica en leucina que se relacionan con mayor riesgo de desarrollar Parkinson, además de variaciones en el cuadro clínico y edad de inicio de síntomas. En cuanto a la enfermedad de Alzheimer, las alteraciones en los genes de la proteína precursora amiloide, presenilina 1 y 2 se relacionan con la forma familiar de la enfermedad; por otra parte, las de apolipoproteína E4 se han identificado en la forma esporádica, por lo que se consideran como el factor de riesgo genético más importante para su desarrollo

Parkinson's and Alzheimer's are the most frequent neurodegenerative diseases worldwide. They have a multifactorial etiology, including genetics, and are of interest in current scientific research. A narrative review was carried out with the aim of determining the genetic alterations associated with these pathologies, as well as their influence on their evolution and response to treatment. Original articles, literature reviews, systematic reviews, meta-analyses in English and Spanish, with publication date between January 1, 2018 and May 20, 2023, were consulted in databases such as PubMed and Medline. MeSH terms "Alzheimer Disease", "Parkinson Disease", "Drug Therapy" and "Mutation" were used. Hereditary risk for Parkinson's disease is usually polygenetic, however, there are genes related to monogenic mutations. Alterations in α-synuclein, glucocerebrosidase and leucine-rich kinase 2 genes have been identified that are related to an increased risk of developing Parkinson's disease, in addition to variations in the clinical picture and age of symptom onset. As for Alzheimer's disease, alterations in the genes of the amyloid precursor protein, presenilin 1 and 2 are related to the familial form of the disease; on the other hand, those of apolipoprotein E4 have been identified in the sporadic form, and are therefore considered to be the most important genetic risk factor for its development

Research progress of biological agents in thyroid-associated ophthalmopathy / 国际眼科杂志(Guoji Yanke Zazhi)

Thyroid-associated ophthalmopathy(TAO)is a rare organ-specific autoimmune disease with an unclear pathogenesis. At present, the treatment still relies mainly on glucocorticoids and traditional immunosuppressants. However, some patients respond poorly to these drugs and experience treatment-related adverse reactions, highlighting the urgent need for novel drugs for TAO treatment. In recent years, with the deepening of research on the pathogenesis of TAO, a multitude of biologics targeting specific targets have emerged. Among them, teprotumumab, which targets the insulin-like growth factor-I receptor(IGF-IR), has been approved by the Food and Drug Administration for the treatment of TAO, and several other biologics are currently in clinical trials. This review provides the latest reference for the clinical prevention, treatment, and research of TAO by summarizing the current clinical research status of biologics targeting IGF-IR, neonatal Fc receptor(FcRn), thyroid-stimulating hormone receptor(TSHR), B cells, cytokines, and other biological agents in TAO and analyzing their impact on clinical treatment and future research trends.

Research progress on drug treatment and drug resistance mechanism of gastrointestinal stromal tumors / 中国临床药理学与治疗学

Gastrointestinal stromal tumors (GIST) are the most common mesenchymal-derived tumors of the gastrointestinal tract. Tyrosine kinase inhibitors (TKIs) are the cornerstone of GIST therapy, but mutations in resistance genes pose many problems for treatment, especially the heterogeneity of KIT resistance mutations. In recent years, with the release of a number of GIST related drug research and experimental results, the great potential of targeted therapy, immunotherapy and combination therapy to treat GIST in different directions has been revealed, providing more therapeutic directions for GIST. This article will review the experimental research and future direction in recent years.

Research advances in second-line therapies for hepatocellular carcinoma after resistance to targeted therapy combined with immunotherapy / 临床肝胆病杂志

In recent years， clinical studies on targeted therapy and immunotherapy for advanced hepatocellular carcinoma used alone or in combination have provided abundant evidence on efficacy and safety for the selection of first-line therapies. However， no consensus has been reached on the selection of second-line therapies in various clinical guidelines for hepatocellular carcinoma， which is caused by the fact that existing evidence is limited to the options after failure of sorafenib and that there is still a lack of high-level evidence for new first-line therapies such as second-line therapies after resistance to targeted therapy and immunotherapy for hepatocellular carcinoma. This article reviews the results of current clinical trials and summarizes the studies on second-line therapies for hepatocellular carcinoma after resistance to first-line targeted therapy and immunotherapy for hepatocellular carcinoma based on the different mechanisms of action of drugs， as well as the research advances in recent years. For hepatocellular carcinoma patients with resistance to first-line targeted therapy and immunotherapy， targeted combination therapy and dual-immune therapy are expected to improve treatment outcome and survival， and more prospective clinical studies are needed in the future to provide effective and safe treatment regimens for hepatocellular carcinoma patients with resistance to targeted therapy and immunotherapy.

@#OBJECTIVE To provide reference for guiding the individualized drug therapy management of imatinib for gastrointestinal stromal tumor （GIST）， with the goal of enhancing patient survival rates and improving their quality of life. METHODS Using a nominal group technique， a multidisciplinary （clinical， pharmaceutical and evidence-based） expert panel was formed to create the Consensus of Chinese Experts on Individualized Medication Management of Imatinib for Gastrointestinal Stromal Tumors outline through joint discussions. The expert panel conducted systematic retrieval， analysis， and summarization of the outline’s content， and reached relevant consensus based on China’s current situation， clinical needs， and research evidence. An external expert panel was also formed， comprising experienced multidisciplinary experts in clinical practice. Delphi method questionnaire was employed to openly collect the external experts’ opinions， which were then organized， summarized， analyzed， provided with feedback， revised， and finally formed into a consensus. RESULTS & CONCLUSIONS The drafting of this consensus included the clinical application of imatinib in neoadjuvant therapy for GIST patients， adjuvant therapy for adult patients with significant risk of recurrence after surgical resection， and drug therapy for patients with recurrent， metastatic， or unresectable tumors； pharmaceutical monitoring and long-term medication management. This consensus provides standardized processes and methods for medical institutions in individualized drug therapy management for GIST patients and holds significant importance in improving the clinical efficacy of imatinib and ensuring drug safety.

Temozolomide alleviates breast carcinoma via the inhibition of EGFR/ERK/ MMP-1 pathway with induction of apoptotic events

Purpose: To evaluate the chemotherapeutic activity of temozolomide counter to mammary carcinoma. Methods: In-vitro anticancer activity has been conducted on MCF7 cells, and mammary carcinoma has been induced in Wistar rats by introduction of 7, 12-Dimethylbenz(a)anthracene (DMBA), which was sustained for 24 weeks. Histopathology, immunohistochemistry, cell proliferation study and apoptosis assay via TUNEL method was conducted to evaluate an antineoplastic activity of temozolomide in rat breast tissue. Results: IC50 value of temozolomide in MCF7 cell has been obtained as 103 μM, which demonstrated an initiation of apoptosis. The temozolomide treatment facilitated cell cycle arrest in G2/M and S phase dose dependently. The treatment with temozolomide suggested decrease of the hyperplastic abrasions and renovation of the typical histological features of mammary tissue. Moreover, temozolomide therapy caused the downregulation of epidermal growth factor receptor, extracellular signal-regulated kinase, and metalloproteinase-1 expression and upstream of p53 and caspase-3 proliferation to indicate an initiation of apoptotic events. Conclusions: The occurrence of mammary carcinoma has been significantly decreased by activation of apoptotic pathway and abrogation of cellular propagation that allowable for developing a suitable mechanistic pathway of temozolomide in order to facilitate chemotherapeutic approach.

Bilateral acute depigmentation of the iris (BADI) and bilateral acute iris transillumination (BAIT): A case series from a center in Brazil

ABSTRACT Bilateral acute depigmentation of the iris and bilateral acute iris transillumination (BAIT) are similar clinical entities. The former causes acute-onset depigmentation of the iris stroma without transillumination, whereas the latter causes depigmentation of the iris pigment epithelium with transillumination. The etiopathogenesis of these conditions is not yet fully understood, but the proposed causes include the use of systemic antibiotics (especially moxifloxacin) and viral triggers. We present a case series of five female patients with a mean age of 41 (32-45) years, all of whom suffered acute onset of bilateral pain and redness of the eyes after moxifloxacin use (oral or topical). It is important for ophthalmologists to be aware of the two forms of iris depigmentation since this case series suggests that SARS-CoV-2 or its empirical treatment with moxifloxacin may trigger iris depigmentation. If this is the case, clinicians will likely see increased incidences of bilateral acute depigmentation of the iris and bilateral acute iris transillumination during and after the COVID-19 pandemic.

Bastidores da prescrição de inibidores de bomba de prótons: uma pesquisa internacional sobre práticas e conhecimentos médicos / Behind the proton pump inhibitor prescription: an international survey on physician practices and knowledge

ABSTRACT Background: Proton pump inhibitors (PPIs) are widely prescribed worldwide, often resulting in their overuse. Consequently, it is essential to identify the likely causes of this overuse to facilitate their appropriate prescription. Objective: This study aims to assess physician prescribing patterns, their knowledge of PPIs, and factors affecting their knowledge. Methods: An online survey was conducted among Latin American and Spanish physicians, collecting the following data: professional information, patterns of PPI usage, familiarity with published evidence, and the management approach in three hypothetical case-scenarios. Participant knowledge was categorized as sufficient or insufficient based on the results of the case scenarios. Subsequently, subgroup analysis was performed based on physician training level, years in practice, specialty, and time since the last PPI literature review. Results: A total of 371 physicians participated in the survey. Thirty-eight percent frequently prescribe PPIs, primarily for prophylactic purposes (57.9%). Eighty percent were unfamiliar with PPI deprescribing strategies, and 54.4% rarely reviewed the ongoing indication of patients taking a PPI. Sixty-four percent demonstrated sufficient knowledge in the case-scenarios. A significant association was observed between specialty type (medical vs surgical: 69.4% vs 46.8%, P<0.001), the timing of the PPI indication literature review (<5 years vs >5 years: 71.4% vs 58.7%, P=0.010), and sufficient knowledge. Conclusion: While most participants prescribed PPIs regularly and for prophylaxis purposes, the majority were unfamiliar with deprescribing strategies and rarely reviewed ongoing indications. Sufficient knowledge is correlated with recent literature reviews and medical specialty affiliation.

RESUMO Contexto: Os inibidores da bomba de prótons (IBPs) são amplamente prescritos em todo o mundo, muitas vezes resultando em seu uso excessivo. Consequentemente, é essencial identificar as prováveis causas desse uso excessivo para facilitar sua prescrição adequada. Objetivo: Este estudo tem como objetivo avaliar o padrão de prescrição dos médicos, seu conhecimento sobre IBPs e fatores que afetam seu conhecimento. Métodos: Uma pesquisa on-line foi conduzida entre médicos latino-americanos e espanhóis, coletando os seguintes dados: informações profissionais, padrões de uso de IBP, familiaridade com evidências publicadas e abordagem de manejo em três casos-cenários hipotéticos. O conhecimento dos participantes foi categorizado em suficiente ou insuficiente com base nos resultados dos cenários de caso. Posteriormente, a análise de subgrupos foi realizada com base no nível de formação do médico, anos de prática, especialidade e tempo desde a última revisão da literatura dos IBPs. Resultados: Um total de 371 médicos participaram da pesquisa. Trinta e oito por cento prescrevem frequentemente IBP, principalmente para fins profiláticos (57,9%). Oitenta por cento não estavam familiarizados com as estratégias de prescrição de IBP, e 54,4% raramente revisaram a indicação contínua de pacientes em uso de IBP. Sessenta e quatro por cento demonstraram conhecimento suficiente nos cenários-caso. Observou-se associação significativa entre o tipo de especialidade (médica vs cirúrgica: 69,4% vs 46,8%, P<0,001), o momento da revisão da literatura de indicação do IBP (<5 anos vs >5 anos: 71,4% vs 58,7%, P=0,010) e conhecimento suficiente. Conclusão: Embora a maioria dos participantes prescrevesse IBPs regularmente e para fins de profilaxia, no entanto, não estava familiarizada com estratégias de prescrição e raramente revisava as indicações em andamento. O conhecimento suficiente está correlacionado com revisões recentes da literatura e afiliação à especialidade médica.

Treatment of orbital lymphatic malformation with oral sirolimus: a case report / Malformação linfática orbital tratada com sirolimo oral: relato de caso

ABSTRACT It is estimated that lymphatic malformations in children account for 6% of all benign vascular malformations. New medical therapies have been developed for the management of lymphatic orbital disease. The purpose of this article was to describe a clinical case of orbital venolymphatic malformation in a 10-year-old boy, causing proptosis and palpebral edema. The lesion was initially treated with local sclerotherapy. However, the lesion relapsed, and was successfully treated with oral sirolimus. Prospective studies are warranted to determine the appropriate dose and extend the indications of sirolimus in these patients.

RESUMO A incidência de malformações linfáticas em crianças é estimada em 6% de todas as malformações vasculares benignas. Têm sido desenvolvidos novos tratamento para doenças linfáticas orbitárias. Nosso objetivo é descrever um caso clínico de malformação venolinfática orbitária em um menino de 10 anos de idade, causando proptose e edema palpebral. A lesão foi tratada inicialmente com escleroterapia local. No entanto, a lesão teve recidiva e foi tratada com sucesso com sirolimo oral. Ainda são necessários estudos prospectivos para estabelecer a dose apropriada e a duração do tratamento com sirolimo nesses pacientes.

Prevalence and antimicrobial resistance profile of pathogens isolated from patients with urine tract infections admitted to a university hospital in a medium-sized Brazilian city

ABSTRACT This study aimed to determine the antibiotic profile of microorganisms isolated from urine samples of patients with community urine tract infections (UTI) admitted to the University Hospital of the Federal University of Sao Carlos to support an appropriate local empirical treatment. A retrospective cross-sectional study was conducted from October 2018 to October 2020. Data from 1,528 positive urine cultures for bacterial pathogens and antibiograms were tabulated. Bacterial species prevalence and their resistance profile were analyzed and compared by sex and age. For Gram-negative fermenting bacteria, resistance rates were compared between patients with previous hospitalization and the total of infections caused by this group. For comparisons, the Chi-square test was performed, using Fisher's exact test when necessary (BioEstat program, adopting p ≤ 0.05). A multivariate analysis was applied to assess the effect of the studied variables in predicting multidrug resistance. Infections were more prevalent in women and older adults. Gram-negative bacteria represented 90.44% of total cultures. In both sexes, E. coli prevalence was significantly higher in adults compared with older adults (p < 0.0001). For several antibiotics, resistance rates were higher in the older adults compared with other ages and in patients with Gram-negative fermenting infections and previous hospitalization compared with the total of infections by this group of bacteria. The closer to the hospitalization, the higher the number of antibiotics with superior resistance rates. Resistance rates for aminoglycosides, carbapenems, ceftazidime, nitrofurantoin, piperacillin+tazobactam, and fosfomycin were less than 20%, considered adequate for empirical treatment. Only hospitalization in the previous 90 days was statistically significant in predicting infections by multidrug-resistant bacteria.

Frequency of Self-Medication and Knowledge about Out-of-Counter Drugs during the COVID-19 Pandemic in a Group of Iranian Dental Students

Abstract Objective: To study the frequency of self-medication and knowledge about out-of-counter drugs during the COVID-19 pandemic in a group of Iranian dental students. Material and Methods: A descriptive cross-sectional study was conducted among dental undergraduates from September 2021 to November 2021 after receiving ethical clearance from the Kerman Medical University Ethical Committee. A valid and reliable questionnaire, consisting of demographic data and questions about self-medication and knowledge about out-of-counter drugs, was sent to participants via E-mail. Data was analyzed by SPSS 26 software by using a t-test. The P-value was considered at a 0.05% significant level. Results: A total of 88 students participated in the study with a mean age of 21.39±3.71 years. Prevalence of self-medication was found in 53.4%. The most common cause for self-medication was headache. Acetaminophen was the most commonly used medicine for self-medication. Females had more self-medication than males, but there was no significant differences. There was no significant differences between entering year to university and self-medication. Younger students had significantly more self-medication (p=0.007). Knowledge about out-of-counter drugs was moderate. Conclusion: Moderate self-medication as noticed. The out-of-counter drugs were the most used. Although out-of-counter drugs seem relatively safe, their improper use can cause serious side effects. Dental students need to be educated regarding appropriate safe medication and out-of-counter drugs.

20% Autologous serum vs. 0.05% cyclosporine and preservative-free artificial tears in the treatment of Sjögren related dry eye / Soro autólogo a 20% versus ciclosporina a 0,05 e lubrificantes oculares sem conservantes no tratamento da síndrome do olho seco relacionada à Sjögren

ABSTRACT Purpose: To compare the 3-month results of treatment with 20% autologous serum or combination treatment with preservative-free artificial tears and 0.05% cyclosporine in patients with dry eye disease due to primary Sjögren's syndrome. Methods: A total of 130 eyes of 65 patients with newly diagnosed dry eye disease due to primary Sjögren's syndrome were included in the study. The patients were divided into two treatment groups: 66 eyes of 33 patients were assigned to the autologous serum treatment group, and 64 eyes of 32 patients were assigned to the combination treatment group. Schirmer test, tear break-up time and Ocular Surface Disease Index (OSDI) scores were recorded at pretreatment and at 3 months of treatment. Results: At 3 months of treatment, the mean Schirmer value and the mean tear break-up time were significantly higher in the combination treatment group (p<0.0001 and p=0.034, respectively). The OSDI score at 3 months was significantly lower in the autologous serum Group (p=0.004). When the two groups were evaluated separately, the improvements in Schirmer, tear break-up time test, and OSDI scores from before to after treatment were statistically significant: p<0.0001, p<0.001, and p<0.0001, respectively, for the authologus serum Group, and p<0.0001, p<0.001, and p<0.0001, respectively, for the combination treatment group. Conclusions: In short-term treatment of dry eye disease due to primary Sjögren's syndrome, treatment with autologous serum was significantly superior to -combination treatment with preservative-free artificial tears and 0.05% cyclosporine in terms of improvement in OSDI scores. Improvements in Schirmer test and tear break-up time scores were significantly superior in the group treated with preservative-free artificial tears and 0.05% cyclosporine.

RESUMO Objetivo: Comparar os resultados de 3 meses de soro autólogo a 20% com um tratamento combinado, ou seja, lubrificantes oculares sem conservantes e ciclosporina a 0,05% em pacientes com síndrome do olho seco devida à síndrome de Sjögren primária. Métodos: Foram incluídos no estudo 130 olhos de 65 pacientes recentemente diagnosticados com síndrome do olho seco devida à síndrome de Sjögren primária. Os pacientes foram divididos em dois grupos de tratamento, 66 olhos de 33 pacientes foram incluídos no grupo de tratamento com soro autólogo e 64 olhos de 32 pacientes foram incluídos no grupo de tratamento combinado com lubrificantes oculares sem conservantes e ciclosporina. Os resultados do teste de Schirmer e do tempo de ruptura do filme lacrimal e os índices de doença da superfície ocular (OSDI) foram registrados antes e depois de três meses de tratamento. Resultados: Três meses após o tratamento, o valor médio do teste de Schirmer foi mais alto com significância estatística no grupo do tratamento combinado com lubrificantes oculares sem conservantes e ciclosporina (p<0,0001) e o tempo de ruptura do filme lacrimal também foi significativamente maior nesse grupo (p=0,034). Também aos três meses, a doença da superfície ocular foi menor com significância estatística no grupo de tratamento com soro autólogo (p=0,004). Quando os dois grupos foram avaliados separadamente, a melhora no teste de Schirmer, o tempo de ruptura e a doença da superfície ocular antes e depois do tratamento tiveram diferenças estatisticamente significativas tanto no grupo de soro autólogo (p<0,0001, p<0,001 e p<0,0001, respectivamente) quanto no grupo de tratamento combinado (p<0,0001, p<0,001 e p<0,0001, respectivamente). Conclusões: No tratamento de curto prazo da síndrome do olho seco devida à síndrome de Sjögren primária, o tratamento com soro autólogo foi significativamente superior ao tratamento com lubrificantes oculares sem conservantes combinados com ciclosporina, em termos de melhora no doença da superfície ocular. As melhoras no teste de Schirmer e no tempo de ruptura do filme lacrimal foram significativamente maiores no grupo de tratamento combinado com lubrificantes oculares sem conservantes e ciclosporina.

Resultados: Se analizaron 9835 pacientes donde la proporción de adherencia fue de 90 % y en el modelo ajustado se evaluó su relación con los antecedentes de no adherencia (ORa:0,52 IC95 °/o:0,40-0,66), grupo farmacológico (2 ITIAN + 1 IP u otro) (ORa:1,22 IC95 %:0,99-1,76), dos tomas al día (ORa:1,02 IC95 %:0,74-1,40), unidades al día (≥ 3) (ORa:0,69 IC95 %:0,47-1,02), reacciones adversas a medicamentos (ORa:0,56 IC95 °%:0,40-0,78), polimedicación (ORa:1,36 IC95 %:1,00-1,85), tiempo TAR (1 a 2 años) (ORa:1,63 IC95 %:1,27-2,09),tiempo TAR (6 a 12 meses) (ORa:1,66 IC95 %:1,27-2,18), tiempo TAR (<6 meses) (ORa:1,36 IC95 %:1,03-1,78), tasa de reclamación de los medicamentos (ORa:0,42 IC95 %:0,32-0,55) y antecedentes PRUM (ORa:0,11 IC95 %:0,09-0,14). Discusión: La proporción de adherencia obtenida es superior a lo descrito para otros países (entre 60-77 %); sin embargo se encuentra que los hallazgos correspondientes al efecto de las variables farmacológicas analizadas son acordes a lo descrito en estudios previos en el tema Conclusión: Los antecedentes de no adherencia, reacciones adversas, tasa de reclamación de los medicamentos y antecedentes de problemas relacionados con el uso de medicamentos son aspectos que reducen la probabilidad de adherencia; mientras que el mayor tiempo de uso del tratamiento aumenta la misma.

Introduction: Adherence to drug treatment promotes viral suppression and reduces long-term resistance to highly active antiretroviral therapy (HAART). Objective: To determine the relationship between the pharmacological aspects and adherence to antiretroviral treatment in a Colombian IPS. Methodology: Cross-sectional analytical study in patients with HIV on antiretroviral treatment between 2012 and 2020. A multiple binary logistic regression model was used for explanatory purposes. Results: A total of 9,835 patients were analyzed where the proportion of adherence was 90 % and in the adjusted model its relationship with history of non-adherence was assessed (ORa: 0,52 95 % CI: 0,40-0,66), pharmacological group (2 NRTI + 1 PI or other) (ORa: 1,22 95 % CI: 0,99-1,76), two doses per day (ORa: 1,02 95 % CI: 0,74-1,40), units per day (≥ 3 ) (ORa: 0,69 95 % CI: 0,47-1,02), adverse drug reactions (ORa: 0,56 95 % CI: 0,40-0,78), polypharmacy (ORa: 1,36 95 % CI : 1,00-1,85), ART time (1 to 2 years) (ORa: 1,63 95 % CI: 1,27-2,09), ART time (6 to 12 months) (ORa: 1,66 95 % CI: 1,27-2,18), ART time (<6 months) (ORa: 1,36 95 % CI: 1,03-1,78), inconsistency in the claim (ORa: 0,42 95 % CI: 0,32-0,55) and PRUM history (ORa: 0,11 95 % CI: 0,09-0,14). Discussion: The proportion of adherence obtained is higher than that described for other countries (between 60-77 %); however, the findings corresponding to the effect of the pharmacological variables analysed are in line with those described in previous studies on the subject. Conclusion: The history of non-adherence, adverse reactions, inconsistencies in the claim fill history and problems related to the use of medications are aspects that reduce the probability of adherence. While the longer time of use of the treatment increases adherence.

REM sleep behavior disorder: update on diagnosis and management / Transtorno comportamental do sono REM: atualização no diagnóstico e manejo

Abstract REM sleep behavior disorder (RBD) is characterized by a loss of atonia of skeletal muscles during REM sleep, associated with acting out behaviors during dreams. Knowledge of this pathology is important to predict neurodegenerative diseases since there is a strong association of RBD with diseases caused by the deposition of alpha-synuclein in neurons (synucleinopathies), such as Parkinson's disease (PD), multiple system atrophy (MSA), and dementia with Lewy bodies (DLB). Proper diagnosis of this condition will enable the use of future neuroprotective strategies before motor and cognitive symptoms. Diagnostic assessment should begin with a detailed clinical history with the patient and bed partner or roommate and the examination of any recorded home videos. Polysomnography (PSG) is necessary to verify the loss of sleep atonia and, when documented, the behaviors during sleep. Technical recommendations for PSG acquisition and analysis are defined in the AASM Manual for the scoring of sleep and associated events, and the PSG report should describe the percentage of REM sleep epochs that meet the criteria for RWA (REM without atonia) to better distinguish patients with and without RBD. Additionally, PSG helps rule out conditions that may mimic RBD, such as obstructive sleep apnea, non-REM sleep parasomnias, nocturnal epileptic seizures, periodic limb movements, and psychiatric disorders. Treatment of RBD involves guidance on protecting the environment and avoiding injuries to the patient and bed partner/roommate. Use of medications are also reviewed in the article. The development of neuroprotective medications will be crucial for future RBD therapy.

Resumo O transtorno comportamental do sono REM (TCSREM) é caracterizado por uma perda de atonia dos músculos esqueléticos durante o sono REM, associada a comportamentos de atuação durante os sonhos. O conhecimento desse transtorno é importante como preditor de doenças neurodegenerativas, uma vez que existe uma forte associação de TCSREM com doenças causadas pela deposição de alfa-sinucleína nos neurônios, como a doença de Parkinson (DP), atrofia de múltiplos sistemas (MSA) e demência com corpos de Lewy (DLB). O diagnóstico adequado dessa condição permitirá o uso de futuras estratégias neuroprotetoras antes do aparecimento dos sintomas motores e cognitivos. A avaliação diagnóstica deve começar com uma história clínica detalhada com o paciente e acompanhante, além de exame de vídeos. A polissonografia (PSG) é necessária para verificar a perda da atonia do sono e, quando documentados, os comportamentos durante o sono. As recomendações técnicas para aquisição e análise de PSG são definidas no Manual da AASM (Scoring of sleep and associated events) e o relatório de PSG deve descrever a porcentagem de períodos de sono REM que atendem aos critérios para REM sem atonia. Além disso, a PSG ajuda a descartar condições que podem mimetizar o TCSREM, como apneia obstrutiva do sono, parassonias do sono não REM, crises epilépticas noturnas, movimentos periódicos dos membros e transtornos psiquiátricos. O tratamento do TCSREM envolve orientações sobre adaptações do ambiente para evitar lesões ao paciente e ao colega de quarto. Medicamentos utilizados são revistos no artigo, assim como o crucial desenvolvimento de medicamentos neuroprotetores.

Importancia de la escala Centor en la atención a pacientes con amigdalitis aguda durante la COVID-19: Serie de casos

Fundamento: En Cuba, durante la pandemia de COVID-19, se puso a prueba la importancia de las escalas clínicas para el tratamiento de pacientes adultos con amigdalitis aguda por no contar con pruebas de detección rápida de antígenos, sin embargo, su uso sigue siendo controversial. Objetivo: Describir los resultados de la aplicación de la escala Centor en la atención a pacientes con amigdalitis aguda durante la COVID-19. Metodología: Se realizó un estudio de serie de casos y se incluyeron los pacientes con amigdalitis aguda diagnosticados en un período de dos años en la consulta externa de Otorrinolaringología del Hospital General Provincial Camilo Cienfuegos, Sancti Spíritus, Cuba. A todos se les aplicó la escala Centor. Resultados: Se incluyeron 114 pacientes. La media de edad fue de 28.9 + 18.7 años, más de la mitad de los pacientes tenían antecedentes de amigdalitis crónica y adenoiditis crónica y eran fumadores activos. Aproximadamente 2 de cada 5 pacientes tuvieron puntuaciones <3 según la escala Centor. Conclusiones: La amigdalitis aguda fue un problema de salud durante la COVID-19 y la escala Centor fue una importante herramienta para la toma de decisiones terapéuticas en pacientes con amigdalitis aguda, aun en condiciones de ausencia de pruebas confirmatorias.

Background: In Cuba, during the COVID-19 pandemic, the clinical scales for adult patients treatment with acute tonsillitis were put under test for not having rapid antigen detection tests, however, its use is still controversial. Objective: To describe the Centor scale application results in the care of patients with acute tonsillitis during COVID-19. Methodology: A case series study was conducted and it included acute tonsillitis patients diagnosed over a two year period in the Otorhinolaryngology external consultation at Camilo Cienfuegos Provincial General Hospital, Sancti Spíritus, Cuba. The Centor scale was applied to all of them. Results: It included 114 patients. The average age was 28.9 + 18.7 years, more than half of the patients had previous history of chronic tonsillitis and chronic adenoiditis and they were active smokers. Approximately 2 out of 5 patients had scores <3 according to the Centor scale. Conclusions: Acute tonsillitis was a health problem during COVID-19 and the Centor scale was an important tool for therapeutic decision in acute tonsillitis patients, even in absence of confirmatory evidence.
