Systematic review on molecular detection of congenital and neonatal infections caused by TORCH and SARS-CoV-2 in newborns' cerebrospinal fluid / Revisáo sistemática sobre deteção molecular de infecções congênitas e neonatais causadas por TORCH e SARS-CoV-2 no líquido cefalorraquidiano de recém-nascidos

ABSTRACT Objective: To verify the use and identify advantages of molecular methods for congenital infections diagnosis in cerebrospinal fluid of neonates. Data source: The review was registered in the International Prospective Register of Systematic Reviews (PROSPERO), under CRD42021274210. The literature search was performed in databases: PubMed, Virtual Health Library/ Latin American and Caribbean Center on Health Sciences Information (VHL/BIREME), Scopus, Web of Science, Excerpta Medica database (EMBASE), Cochrane, ProQuest, and EBSCOhost. The search was carried out from August to October 2021 and updated in December 2022, respecting the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The selection sequence was: 1) Duplicate title removal; 2) Examination of titles and abstracts; 3) Full-text retrieval of potentially relevant reports; and 4) Evaluation of the full text according to eligibility criteria by two independent authors. Inclusion criteria considered randomized and non-randomized control trials, longitudinal, cross-sectional, and peer-reviewed studies in humans, published in English, Spanish, Italian, and Portuguese, with newborns up to 28 days old who had congenital neuroinfections by toxoplasmosis, rubella, cytomegalovirus, herpes simplex (TORCH), and others such as Treponema pallidum, Zika, parvovirus B-19, varicella zoster, Epstein-Barr, and SARS-CoV2, diagnosed by polymerase chain reaction (PCR). Two evaluators extracted the following information: author, year of publication, nationality, subjects, study type, methods, results, and conclusion. Data synthesis: The most studied pathogen was herpes simplex. Several articles reported only nonspecific initial symptoms, motivating the collection of cerebrospinal fluid and performing PCR for etiological investigation. Conclusions: Molecular methods are effective to detect pathogen genomes in cerebrospinal fluid, which can impact clinical evolution and neurological prognosis.

Um esclarecimento sobre a real necessidade de realizar a reposição hormonal de testosterona no homem / A clarification on the real need for testosterone hormone replacement in men / Una aclaración sobre la necesidad real de sustituir la hormona testosterona en los hombres

O artigo é uma revisão sobre os aspectos relacionados ao envelhecimento masculino e necessidades de tratamentos, com ênfase no hipogonadismo tardio, baixa produção de testosterona e possível desenvolvimento do Distúrbio Androgênico do Envelhecimento Masculino (DAEM). O objetivo foi apresentar o DAEM e suas implicações sobre a qualidade de vida do paciente para promover e validar o tratamento, quando realmente for apropriado, para esse quadro clínico. Utilizou-se como a fonte de pesquisa Google Acadêmico, banco de dados Biblioteca Virtual em Saúde e do PubMed foram obtidos artigos com as aplicações dos seguintes filtros: 2010-2023 e descritores em saúde (andropausa, reposição hormonal, testosterona, DAEM, hipogonadismo e síndromes metabólicas). Os critérios de inclusão utilizados foram a disponibilidade integral dos artigos, ter os idiomas inglês e português, e abordar o tema da Doença Androgênica do Envelhecimento, todas as suas repercussões sobre a qualidade de vida do homem e, sobretudo, o seu tratamento. Para excluir artigos encontrados na busca, foram observadas obras que apenas tangenciam o tema e tinham enfoque em outros aspectos, como: estética e esporte. Após a aplicação do método, 14 trabalhos foram selecionados por estabelecerem grande relação com o tema. Esse distúrbio acarreta para o indivíduo um conjunto de sinais e sintomas capazes de comprometer sua qualidade de vida: disfunção erétil, baixa libido, obesidade, redução de massa magra ou sarcopenia, osteoporose e distúrbios do humor. O diagnóstico é feito clinicamente e através de exames laboratoriais de dosagem sérica de testosterona. Perante a confirmação diagnóstica e sem patologizar processos fisiológicos do envelhecimento, o tratamento indicado é a reposição de testosterona que tende a normalizar o quadro do idoso por amenizar ou finalizar os sinais e sintomas desse paciente, proporcionando-o uma terceira idade com qualidade de vida. Vale destacar que as disposições de formulações de testosterona são inúmeras: orais, transdérmicas, intramusculares ou injetáveis. A via de administração depende da situação individual de cada paciente e cada tipo de medicamento tem seus benefícios se comparado aos outros, seja por comparação entre efeitos colaterais, estabilidade de níveis séricos hormonais, custo e acesso. O DAEM precisa ser identificado e diagnosticado naqueles pacientes que necessitam de um tratamento por apresentar sinais e sintomas prejudiciais ao bem-estar. Para isso, a indústria farmacêutica disponibiliza uma gama de formas de administração de testosterona. Entretanto, é preciso ter clareza sobre a real necessidade de medicar um paciente.

The article is a review of aspects related to male aging and treatment needs, with an emphasis on late-onset hypogonadism, low testosterone production and the possible development of Androgenic Male Aging Disorder (AMAD). The aim was to present the AMAD and its implications for the patient's quality of life in order to promote and validate treatment, where appropriate, for this clinical condition. The search source used was Google Scholar, the Virtual Health Library database and PubMed, where articles were obtained using the following filters: 2010-2023 and health descriptors (andropause, hormone replacement, testosterone, AMAD, hypogonadism and metabolic syndromes). The inclusion criteria used were that the articles were available in full, that they were in English and Portuguese, and that they dealt with the subject of Androgenic Ageing Disorder, all its repercussions on men's quality of life and, above all, its treatment. To exclude articles found in the search, we looked at works that only touched on the subject and focused on other aspects, such as aesthetics and sport. After applying the method, 14 articles were selected because they were closely related to the topic. This disorder leads to a set of signs and symptoms that can compromise the individual's quality of life: erectile dysfunction, low libido, obesity, reduced lean mass or sarcopenia, osteoporosis and mood disorders. The diagnosis is made clinically and through laboratory tests of serum testosterone levels. Once the diagnosis has been confirmed and without pathologizing the physiological processes of ageing, the treatment indicated is testosterone replacement, which tends to normalize the condition of the elderly by easing or ending the signs and symptoms of the patient, providing them with a quality old age. It's worth noting that there are many different formulations of testosterone: oral, transdermal, intramuscular or injectable. The route of administration depends on the individual situation of each patient and each type of medication has its benefits compared to the others, whether it's a comparison of side effects, stability of serum hormone levels, cost and accessibility. AMAD needs to be identified and diagnosed in those patients who need treatment because they have signs and symptoms that are detrimental to their well-being. To this end, the pharmaceutical industry offers a range of forms of testosterone administration. However, it is necessary to be clear about the real need to medicate a patient.

El artículo es una revisión de los aspectos relacionados con el envejecimiento masculino y las necesidades de tratamiento, con énfasis en el hipogonadismo de inicio tardío, la baja producción de testosterona y el posible desarrollo del Trastorno Androgénico del Envejecimiento Masculino (TAME). El objetivo fue presentar el TAME y sus implicaciones en la calidad de vida del paciente, con el fin de promover y validar el tratamiento de esta condición clínica, cuando sea apropiado. La fuente de búsqueda utilizada fue Google Scholar, la base de datos de la Biblioteca Virtual de Salud y PubMed, donde se obtuvieron artículos utilizando los siguientes filtros: 2010-2023 y descriptores de salud (andropausia, reemplazo hormonal, testosterona, TAME, hipogonadismo y síndromes metabólicos). Los criterios de inclusión utilizados fueron que los artículos estuvieran disponibles en su totalidad, en inglés y portugués, y que abordaran el tema del Trastorno Androgénico del Envejecimiento, todas sus repercusiones en la calidad de vida de los hombres y, sobre todo, su tratamiento. Para excluir los artículos encontrados en la búsqueda, se consideraron los trabajos que sólo tocaban el tema y se centraban en otros aspectos, como la estética y el deporte. Tras aplicar el método, se seleccionaron 14 artículos por estar estrechamente relacionados con el tema. Este trastorno conlleva un conjunto de signos y síntomas que pueden comprometer la calidad de vida del individuo: disfunción eréctil, libido baja, obesidad, reducción de la masa magra o sarcopenia, osteoporosis y trastornos del estado de ánimo. El diagnóstico se realiza clínicamente y mediante pruebas de laboratorio de los niveles séricos de testosterona. Una vez confirmado el diagnóstico y sin patologizar los procesos fisiológicos del envejecimiento, el tratamiento indicado es el reemplazo de testosterona, que tiende a normalizar la condición del anciano, aliviando o terminando con sus signos y síntomas, proporcionándole una vejez con calidad de vida. Cabe destacar que existen diversas formulaciones de testosterona: oral, transdérmica, intramuscular o inyectable. La vía de administración depende de la situación individual de cada paciente y cada tipo de medicación tiene sus ventajas frente a las demás, ya sea en comparación con los efectos secundarios, la estabilidad de los niveles séricos de la hormona, el coste y la accesibilidad. Es necesario identificar y diagnosticar el TAME en aquellos pacientes que necesitan tratamiento porque presentan signos y síntomas perjudiciales para su bienestar. Para ello, la industria farmacéutica ofrece diversas formas de administración de testosterona. Sin embargo, es necesario tener clara la necesidad real de medicar a un paciente.

Co-occurrence of oral pemphigus vulgaris and herpes simplex virus infection in a young patient with Crohn's disease: report of a rare case of oral lesions during anti-TFN alpha and immunomodulator therapy.

BACKGROUND: Pemphigus vulgaris (PV) is a potentially life-threatening mucocutaneous autoimmune disease that affects desmoglein-1 and desmoglein-3, leading to intraepithelial vesiculobullous lesions. In the oral mucosa, PV lesions can mimic other diseases such as mucous membrane pemphigoid, other forms of pemphigus, recurrent aphthous stomatitis, erythema multiforme, Stevens-Johnson syndrome, and virus-induced ulcers like herpes simplex virus (HSV), making diagnosis challenging. The co-occurrence of PV with Crohn's disease is rare and predominantly seen in younger patients. The therapeutic mainstay for both PV and Crohn's disease usually involves systemic corticosteroids combined with immunosuppressants and immunobiological drugs. Literature indicates that the use of these drugs, particularly TNF-alpha inhibitors, for managing autoimmune diseases like Crohn's can potentially induce other autoimmune diseases known as autoimmune-like syndromes, which include episodes of lupus-like syndrome and inflammatory neuropathies. There are few cases in the literature reporting the development of PV in individuals with CD undergoing infliximab therapy. CASE REPORT: A young female with severe Crohn's disease, treated with the TNF-alpha inhibitor infliximab, developed friable pseudomembranous oral ulcerations. Histopathological and immunofluorescence analyses confirmed these as PV. The treatment included clobetasol propionate and low-level photobiomodulation, which resulted in partial improvement. The patient later experienced severe intestinal bleeding, requiring intravenous hydrocortisone therapy, which improved both her systemic condition and oral lesions. Weeks later, new ulcerations caused by herpes virus and candidiasis were identified, leading to treatment with oral acyclovir, a 21-day regimen of oral nystatin rinse, and photodynamic therapy, ultimately healing the oral infections. To manage her condition, the gastroenterologists included methotrexate (25 mg) in her regimen to reduce the immunogenicity of infliximab and minimize corticosteroid use, as the patient was in remission for Crohn's disease, and the oral PV lesions were under control. CONCLUSION: Young patients with Crohn's disease should be referred to an oral medicine specialist for comorbidity investigation, as oral PV and opportunistic infections can arise during immunosuppressive therapy. The use of TNF-alpha inhibitors in patients treated for inflammatory bowel disease, such as Crohn's, should be carefully evaluated for potential side effects, including oral PV.

People living with HIV co-infected with the Kaposi Sarcoma-associated Herpes Virus have a distinct HIV Tat profile and higher rates of antiretroviral virologic failure, more evident among those with Kaposi's sarcoma.

Kaposi sarcoma (KS) is a neoplasm of vascular origin that promotes angiogenesis and the growth of endothelial cells triggered by the Kaposi Sarcoma-associated Herpes Virus (KSHV). When associated with HIV, KSHV becomes more aggressive and rapidly evolves. The HIV-1 TAT protein can be essential in developing AIDS-associated KS by promoting angiogenesis and increasing KSHV replication. Therefore, we evaluated the genetic profile of the first exon of tat gene among groups of people living with HIV (PLHIV) with (case group, n = 36) or without KS, this later with (positive control group, n = 46) and without KSHV infection (negative control group, n = 24); all individuals under antiretroviral therapy. The genetic diversity, the DN/DS ratio, and the genetic entropy of the first exon of tat were higher in the case group, followed by the positive control group, which was higher than the negative control group. The number of tat codons under positive selection was seven in the case group, six in the positive control group, and one in the negative control group. The prevalence of HIV viral loads below the detection limit was equal in the case and positive control groups, which were lower than in the negative control group. The mean CD4+ T cell counts were higher in the negative control group, followed by the positive control group, and followed by the case group. These results emphasize the negative influence of KSHV in antiretroviral treatment, as well as the HIV-specific TAT profile among PLHIV who developed KS.

High silent prevalence of human herpesvirus 1 (HSV-1) infection affecting the indigenous reservation of the municipality of Dourados, Central-West Brazil.

BACKGROUND: The indigenous population located in the central region of Brazil, is the second largest in terms of population size in the country. The Indigenous Reserve of Dourados has risk factors that increase the vulnerability of the indigenous population to infectious diseases, especially Human alphaherpesvirus (HSV-1), a neglected disease with high prevalence in priority populations in developing countries. The virus can also cause many more severe diseases, including widespread neonatal infections, herpetic keratitis, and herpes encephalitis, which can be fatal if left untreated. We estimated the prevalence of anti-HSV-1 antibodies and correlated it with the demographic and behavioral characteristics of the Indigenous population of the Jaguapirú and Bororó villages (Dourados, Mato Grosso do Sul (MS), Brazil). METHODS: Our approach was cross-sectional. From March 2017 to November 2018. Using anti-HSV-1 (Gg1) IgM and anti-HSV-1 (gG1) IgG Euroimmun and the detection and quantification of HSV-1 viral load in plasma samples, through real-time PCR. The maps were constructed using QGIS and the statistical analyses using R Studio software. RESULTS: A total of 1138 individuals (> 18 years old) were enrolled. The prevalence of anti-HSV-1 IgM and IgG were 20% and 97.5%, respectively. The prevalence of anti-HSV-1 antibodies for IgG was higher in both sexes. Anti-HSV-1 IgM antibodies were present in 17.1%, 21.2%, 12.5%, and 22% of the participants with urinary problems, genital wounds, genital warts, and urethral discharge, respectively. Real-time PCR was used for confirmatory testing; HSV-1 DNA was detected in 25.6% (54/211) of anti-HSV1 IgM-positive samples. Viral loads ranged from 5.99E + 02 to 3.36E + 13. CONCLUSIONS: The seroprevalence of HSV-1 IgM and detection of HSV-1 DNA in the Indigenous population confirmed high silent prevalence. Furthermore, the seroprevalence of HSV-1 in the Indigenous population was higher than that reported in the general adult Brazilian population. Various socioeconomic factors, drug use, and health and sexual behaviors could contribute to the facilitation of HSV-1 transmission in the Indigenous population. Our results may help develop culturally appropriate intervention programs that eliminate health access barriers and improve the implementation of public health policies aimed at promoting information regarding the prevention, treatment, and control of HSV-1 infection in Brazilian Indigenous populations.

Not Always Toxoplasmosis: Active Retinochoroiditis Presumably Secondary to Herpes in Eyes with Hyperpigmented Retinochoroidal Previous Scars.

PURPOSE: To demonstrate that the presence of active retinochoroiditis in eyes with previous hyperpigmented old retinochoroidal lesions is not exclusive of ocular toxoplasmosis. METHODS: A case series was constructed by reviewing medical records. RESULTS: Four Brazilian patients presenting active posterior uveitis in eyes with previous hyperpigmented old retinochoroidal lesions were identified. Ocular toxoplasmosis was ruled out in all cases. One case had viral etiology confirmed through vitreous PCR (HSV-2 was positive), and the other 3 cases had a presumed diagnosis of herpetic posterior uveitis. CONCLUSION: Focus active retinitis adjacent to an old cicatricial lesion should not be considered pathognomonic of toxoplasmosis and viral etiology must be considered.

Mucosal Site Detection of Herpes Simplex Virus in Neonates.

From 2001 to 2023, 17 (14%) of 120 neonates with confirmed herpes simplex virus infection tested positive for herpes simplex virus by polymerase chain reaction (PCR) from only mucosal sites without a clinical mucosal lesion. Whether mucosal PCR positivity reflects early infection that may lead to recognizable disease, transient colonization, or a false-positive PCR result remains a clinical conundrum and warrants further study.

Clinical guidelines for herpes labialis: recommendations and quality evaluation according to AGREE II.

Cold sores require Healthcare professionals to employ specific approaches for prevention and management, with the need for effective therapeutic guidelines and ongoing improvement in patient care. AIM: To evalúate the methodological quality of Clinical Guidelines (CG), clinical guides and manuals for care of the population affected by herpes labialis, to verify their compliance with evidence-based health standards. MATERIALS AND METHOD: A search was conducted for CG on labial herpes in the MedicalLiteratureAnalysis andRetrieval System Online (Medline) database, Google Scholar, Brazilian Virtual Health Library (BVS), and sites of institutions/professional categories, using the descriptors "herpes labialis" or "oral herpes". Document quality was assessed using the Appraisal of Guidelines for Research & Evaluation Instrument (AGREE II). The Kappa test was used to avoid randomness or poor agreement between results. RESULTS: Analysis of the 12 selected publications on the management of labial herpes revealed flaws in quality, as the publications did not follow a quality standard. The main quality flaws identified were in "rigor in development" and "applicability. ". CONCLUSIONS: Priorities need to be redefined in the development of CG for clinical practice related to fever blisters to reduce the variability of the quality standard, and generate reliable, applicable recommendations.

Immune Deficiency/Dysregulation Associated Lymphoid Proliferations, EBV+ In Persons Living With HIV

ABSTRACT Background: The 5th edition of the World Health Organization Classification of Hematolymphoid Tumors recently defined immune deficiency/dysregulation (IDD)-associated-lymphoid-proliferations in HIV settings, where information is scarce, often gone under or misdiagnosed. Objectives: To describe the clinical picture, histopathology, and outcomes of IDD-associated-lymphoid-proliferations Epstein-Barr virus+ (EBV) in people living with HIV without organ transplantation, antiretroviral therapy (ART) treated. Methods: HIV+ patients diagnosed with IDD-associated-lymphoid-proliferations seen at an academic medical center in Mexico from 2016 to 2019 were included. Immunohistochemical studies, in situ hybridization, and polymerase chain reaction analysis for EBV and LMP1 gene deletions were performed and correlated with clinical data. Results: We included 27 patients, all men who have sex with men, median age 36 years (interquartile range [IQR] 22-54). The median baseline CD4+ T cells were 113/mL (IQR 89-243), the CD4+/CD8+ ratio was 0.15 (IQR: 0.09-0.22), and the HIV viral load was 184,280 copies/mL (IQR: 76,000-515,707). Twenty patients (74.07%) had IDD-associated-lymphoid-proliferations hyperplasia plasma cell type EBV+, 3 (11.1%) had hyperplasia mononucleosis-like type (IM-type), 1 patient (3.70%) had florid follicular hyperplasia, 3 (11.1%) IDD-associated-lymphoid-proliferations polymorphic type, and there were 22 cases (81.4%) of synchronic Kaposi Sarcoma. Two patients were diagnosed with Hodgkin lymphoma following a second positron emission tomography-computed tomography scan-guided biopsy. The median follow-up was 228 weeks (IQR 50-269); 6 patients died (22.2%) of causes unrelated to IDD-associated-lymphoid-proliferations related. Conclusion: IDD-associated-lymphoid-proliferations EBV+ occured in severely immunosuppressed HIV+ patients, a high percentage of whom had concomitant Kaposi sarcoma. The prognosis was good in patients treated only with ART.

Oral herpes simplex virus infection in patients undergoing chemotherapy - an integrative review.

Aim: The purpose of this study is to undertake an integrative literature review in order to determine the prevalence, etiology, and reactivation of oral HSV infection in patients receiving chemotherapy (CT). Methods: The study was carried out in the PubMed/MEDLINE, Embase, Virtual Health Library, and Scopus databases, using the descriptors "Herpes Simplex", "Viral Diseases", "Mouth", and "Antineoplastic Agents". Results: The findings suggest that HSV infection is widespread in this group of patients and can be severe. HSV infection is frequent in CT patients, and treatment should begin as soon as it is feasible, utilizing antivirals to avoid future difficulties, as patients are immunocompromised. Conclusion: It is critical for health professionals to be fully informed on the dangers and treatment choices available, with the most appropriate therapy for each circumstance. Furthermore, more recent research with acceptable methodological rigor is required to better quantify the prevalence of HSV in these patients.

Immune Deficiency/Dysregulation Associated Lymphoid Proliferations, EBV+ In Persons Living With HIV.

The prognosis was good in patients treated only with ART.

In Vitro Effect of 9,9'-Norharmane Dimer against Herpes Simplex Viruses.

Herpes simplex virus (HSV) infections are highly widespread among humans, producing symptoms ranging from ulcerative lesions to severe diseases such as blindness and life-threatening encephalitis. At present, there are no vaccines available, and some existing antiviral treatments can be ineffective or lead to adverse effects. As a result, there is a need for new anti-HSV drugs. In this report, the in vitro anti-HSV effect of 9,9'-norharmane dimer (nHo-dimer), which belongs to the ß-carboline (ßC) alkaloid family, was evaluated. The dimer exhibited no virucidal properties and did not impede either the attachment or penetration steps of viral particles. The antiviral effect was only exerted under the constant presence of the dimer in the incubation media, and the mechanism of action was found to involve later events of virus infection. Analysis of fluorescence lifetime imaging data showed that the nHo-dimer internalized well into the cells when present in the extracellular incubation medium, with a preferential accumulation into perinuclear organelles including mitochondria. After washing the host cells with fresh medium free of nHo-dimer, the signal decreased, suggesting the partial release of the compound from the cells. This agrees with the observation that the antiviral effect is solely manifested when the alkaloid is consistently present in the incubation media.

Vaccines in cardiology, an underutilized strategy to reduce the residual cardiovascular risk.

Cardiovascular diseases stand as the leading cause of mortality among adults globally. For decades, comprehensive evidence has underscored the correlation between infections, particularly those involving the respiratory system, and an elevated risk of cardiovascular and cerebrovascular events, as well as all-cause mortality. The mechanisms through which infections heighten cardiovascular events are intricate, encompassing immune system activation, systemic inflammation, hypercoagulable states, sympathetic system activation, and increased myocardial oxygen demand. Respiratory infections further contribute hypoxemia to this complex interplay. These mechanisms intertwine, giving rise to endothelial dysfunction, plaque ruptures, myocardial depression, and heart failure. They can either instigate de novo cardiovascular events or exacerbate pre-existing conditions. Compelling evidence supports the safety of influenza, pneumococcal, herpes zoster, COVID-19 and respiratory syncytial virus vaccines in individuals with cardiovascular risk factors or established cardiovascular disease. Notably, the influenza vaccine has demonstrated safety even when administered during the acute phase of a myocardial infarction in individuals undergoing angioplasty. Beyond safety, these vaccinations significantly reduce the incidence of cardiovascular events in individuals with an augmented cardiovascular risk. Nevertheless, vaccination rates remain markedly suboptimal. This manuscript delves into the intricate relationship between infections and cardiovascular events. Additionally, we highlight the role of vaccinations as a tool to mitigate these occurrences and reduce residual cardiovascular risk. Finally, we emphasize the imperative need to optimize vaccination rates among individuals with heart diseases.

Características de recién nacidos hijos de madre con IgM positiva para el Virus Herpes Simplex

Introducción: El herpes connatal es una entidad infrecuente asociada a elevada morbimortalidad. La probabilidad de transmisión al recién nacido va de 5% al 85%. El diagnóstico se dificulta por falta de clínica, serología no confiable y por la no disponibilidad de PCR en los servicios públicos de países en vías de desarrollo. La IgM en gestantes podría ser utilizada como un marcador de sospecha para evaluar al neonato. Objetivo: Caracterizar a los recién nacidos, hijos de gestantes con IgM positiva para HVS 1-2 y la frecuencia de encefalitis en los infantes. Materiales y métodos : Estudio observacional, descriptivo, prospectivo, realizado de mayo de 2020 a octubre de 2021. Se incluyeron recién nacidos (RN) de madres con IgM positiva para Herpes Virus Simplex (HVS) a partir de la segunda mitad del embarazo. En el RN se realizó serología IgG e IgM, y además, PCR- RT para HVS 1-2 en sangre y/o LCR, excluyéndose los nacidos en otras maternidades y/o sin datos de serología materna. Resultados: 36 pacientes. Edad materna 28 años (DS + 4), 5% con antecedentes de HVS, 61% cesárea. 36% prematuros, 13% RCIU. Síntomas agudos en el RN 22%. De ellos, 19% plaquetopenia, 44% alteración de GOT. 63% PCR HVS en sangre y 44% en LCR. Se encontró hemorragia, hidrocefalia, leucomalacia en 27%. No se encontró diferencias en la expresión clínica por tipo de parto. Conclusiones: Los RN hijos de gestantes con IgM positiva para VHS desde la segunda mitad del embarazo o periparto, presentaron infección por VHS determinada por PCR en sangre o LCR, independiente de la vía del parto. El diagnóstico serológico en embarazadas permite la pesquisa, diagnóstico y tratamiento temprano del RN.

Introduction: neonatal herpes is a rare entity associated with high morbidity and mortality. The probability of transmission to the newborn ranges from 5% to 85%. The diagnosis is difficult due to the lack of clinical signs, unreliable serology and the non-availability of PCR in public services in developing countries. IgM in pregnant women could be used as a suspected marker to evaluate the neonate. Objective: To characterize newborn children of pregnant women with positive IgM for HSV 1-2 and the prevalence of encephalitis in infants. Materials and methods: Observational, descriptive, prospective study, carried out from May 2020 to October 2021. Newborns (NB) of mothers with positive IgM for Herpes Virus Simplex (HSV) from the second half of pregnancy were included. In newborns, IgG and IgM were performed, and in addition, PCR-RT for HSV 1-2 in blood and/or CSF, excluding those born in other hospitales and/or without maternal serology data. Results: We included 36 patients. Maternal age was 28 years (DS + 4), 5% with a history of HSV. 61% were delivered via cesarean section, 36% were premature, 13% had IUGR. 22% of the newborns had acute symptoms. 19% had thrombocytopenia, 44% had GOT alteration. 63% were PCR positive for HSV in serum and 44% were CSF-positive. Hemorrhage, hydrocephalus and leukomalacia were found in 27%. No differences were found in clinical expression by type of delivery. Conclusions: Newborns born to pregnant women with positive IgM for HSV from the second half of pregnancy or peripartum, presented HSV infection as determined by PCR in blood or CSF, regardless of the route of delivery. Serological diagnosis in pregnant women allows early screening, diagnosis and treatment of the NB.

Task force of the Brazilian Society of Otology - evaluation and management of peripheral facial palsy.

OBJECTIVE: To review key evidence-based recommendations for the diagnosis and treatment of peripheral facial palsy in children and adults. METHODS: Task force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on peripheral facial palsy were eligible for inclusion. The American College of Physicians' guideline grading system and the American Thyroid Association's guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. RESULTS: The topics were divided into 2 main parts: (1) Evaluation and diagnosis of facial palsy: electrophysiologic tests, idiopathic facial palsy, Ramsay Hunt syndrome, traumatic peripheral facial palsy, recurrent peripheral facial palsy, facial nerve tumors, and peripheral facial palsy in children; and (2) Rehabilitation procedures: surgical decompression of the facial nerve, facial nerve grafting, surgical treatment of long-term peripheral facial palsy, and non-surgical rehabilitation of the facial nerve. CONCLUSIONS: Peripheral facial palsy is a condition of diverse etiology. Treatment should be individualized according to the cause of facial nerve dysfunction, but the literature presents better evidence-based recommendations for systemic corticosteroid therapy.

Clinical guidelines for herpes labialis: recommendations and quality evaluation according to AGREE II / Diretrizes clínicas para o herpes labial: recomendares e avalia$ao de qualidade de acordo com o AGREE II

ABSTRACT Cold sores require Healthcare professionals to employ specific approaches for prevention and management, with the need for effective therapeutic guidelines and ongoing improvement in patient care. Aim To evalúate the methodological quality of Clinical Guidelines (CG), clinical guides and manuals for care of the population affected by herpes labialis, to verify their compliance with evidence-based health standards. Materials and Method A search was conducted for CG on labial herpes in the MedicalLiteratureAnalysis andRetrieval System Online (Medline) database, Google Scholar, Brazilian Virtual Health Library (BVS), and sites of institutions/professional categories, using the descriptors "herpes labialis" or "oral herpes". Document quality was assessed using the Appraisal of Guidelines for Research & Evaluation Instrument (AGREE II). The Kappa test was used to avoid randomness or poor agreement between results. Results Analysis of the 12 selected publications on the management of labial herpes revealed flaws in quality, as the publications did not follow a quality standard. The main quality flaws identified were in "rigor in development" and "applicability. " Conclusions Priorities need to be redefined in the development of CG for clinical practice related to fever blisters to reduce the variability of the quality standard, and generate reliable, applicable recommendations.

Actualización de las recomendaciones de vacunación en adultos con enfermedades respiratorias. Documento de la Asociación Argentina de Medicina Respiratoria para los neumonólogos, 2023 / Recommendations in Adults with Respiratory Diseases. Document from the Argentinian Association of Respiratory Medicine for Pulmonologists, 2023

RESUMEN Los adultos fumadores, con comorbilidades, y los ancianos tienen mayor riesgo de contraer infecciones pulmonares y de tener peor evolución. La neumonía adquirida en la comunidad debida a virus, neumococo, además de otras bacterias y microorga nismos "atípicos" afecta tanto a adultos sanos como enfermos. La vacuna antigripal se diseña el verano anterior orientada a las cepas esperadas para la temporada siguiente. Su eficacia depende fundamentalmente de la variante viral que finalmente sea la responsable del brote. La vacuna anti-neumocócica polisacárida existe desde 1983 y será inexorablemente reemplazada por vacunas conjugadas de mayor eficacia, que previenen la infección por los serotipos presentes en la vacuna. La inmunización contra SARS-CoV-2 aceleró la reducción del contagio y la gravedad de COVID-19 notablemente. La vacuna acelular para Bordetella pertussis no está en el calendario de adultos, aun cuando vacunarlos fortalece el control del contagio infantil. La vacunas doble bacteriana (difteria y tétanos), y triple (doble + pertusis), y contra sarampión, varicela, rubeola, HPV, Haemophylus influenzae, meningococo, herpes zóster, fiebre hemorrágica argentina y fiebre amarilla están disponibles, pero son de uso limitado. Nuevas vacunas, como la recientemente aprobada por los CDC contra el virus sincicial respiratorio, pronto estarán disponibles.

ABSTRACT Adult smokers, subjects with comorbidities, and the elderly are at higher risk of pulmo nary infections and worse outcomes. Community-acquired pneumonia due to viruses, pneumococcus, other bacteria, and "atypical" microorganisms affects healthy and sick adults. The flu vaccine is designed the previous summer for the strains expected for the following season. Its effectiveness depends fundamentally on the viral variant ultimately responsible for the outbreak. The anti-pneumococcal polysaccharide vaccine has been available since 1983 and it is expected to be replaced by conjugate vaccines which are more effective in preventing infection due to serotypes present in the vaccine. Immuniza tion against SARS-CoV-2 diminished contagion and severity of COVID-19 remarkably. The acellular vaccine for Bordetella pertussis is not on the schedule for all adults, even when vaccinating them strengthens the control of contagion in children. Double bacterial (diphtheria and tetanus), triple (double + pertussis), measles, varicella, rubella, HPV, Haemophilus influenzae, meningococcal, herpes zoster, Argentine hemorrhagic fever, and yellow fever vaccines are available, but their use is limited. New vaccines such as the one recently approved by the CDC against respiratory syncytial virus will soon be available.

Pseudotumoral herpes genitalis in a woman living with HIV: Diagnosis and treatment challenges.

Herpes simplex virus (HSV) is the leading cause of genital ulcers worldwide. In rare cases, mostly among immunocompromised hosts, HSV infections can present as hypertrophic pseudotumoral forms simulating malignancies or often mistaken as other viral infections, usually resistant to conventional antiviral therapy and often requiring alternative therapeutic approaches. A high level of clinical suspicion is needed. We present a case of woman living with HIV with pseudotumoral vulvar herpes refractory to oral acyclovir, successfully treated with systemic foscarnet and topical imiquimod.
