Objective: the aim of this study was to relate sociodemographic, epidemiological and clinical conditions to the occurrence of severe cases of HZ in reference hospital of Fortaleza. Methods: this is a cross-sectional analytical study, based on medical records of patients admitted from 2009 to 2018. Pearson's x2 test or Fisher's exact test were used when appropriate. Results: we analyzed 196 medical records. The presence of complications occurred in 69.9%, the most affected region was the cranial (68.9%), and 1.5% died. The presence of vesicles (PR=1.37; 95%CI: 1.03-1.82; p=0.01) and the choice of antibiotic associated antiviral therapy (PR=0.58; 95%CI: 0.46-0.73; p=0.00) were significantly associated with the severity. Conclusions: the disease may be more severe at ages over 50. The presence of lesions in vesicles was associated with a higher prevalence of complications and the use of antibiotics and antivirals as a protective factor.

Introducción: El láser de baja potencia tiene un amplio uso en la práctica médica actual. Existe un gran número de pacientes con afecciones agudas o crónicas que pueden ser tratados con esta terapia, con resultados alentadores, muy superiores a los obtenidos con el uso de la terapéutica convencional. Objetivo: Evaluar la efectividad del láser de baja potencia como terapia adyuvante para reducir el tiempo de respuesta al alivio del dolor en pacientes con herpes zóster. Métodos: Se realizó un estudio cuasiexperimental, de intervención terapéutica, en 21 pacientes con herpes zóster, atendidos en el Servicio de Fisiatría del Policlínico del MININT de Santiago de Cuba, desde enero de 2016 hasta junio de 2017. Se conformaron 2 grupos de forma aleatoria: los integrantes del primero recibieron el tratamiento habitual con aciclovir, vitaminas y analgésico (control); los del segundo, aciclovir, vitaminas y laserterapia (intervención). Resultados: Se observó que en el grupo de intervención la intensidad del dolor fue disminuyendo en relación con la evaluación inicial. Así, en la quinta sesión se apreció mayor porcentaje de pacientes con alivio del dolor que en el grupo control, al igual que en la décima sesión y 21 días después, de ahí la efectividad del tratamiento. Conclusiones: Con el empleo del láser de baja potencia los pacientes con herpes zóster presentaron una mejoría del dolor en menor tiempo, con una respuesta satisfactoria expresada en la totalidad de ellos, por lo que se recomienda su utilización como terapia adyuvante.

Introduction: The low power laser has a wide use in the current medical practice. There is a great number of patients with acute or chronic conditions that can be treated with this therapy, with encouraging results, far better than those obtained with the use of conventional therapy. Objective: To evaluate the effectiveness of low power laser as adjuvant therapy to reduce the response time to pain relief in patients with zoster herpes. Methods: A quasi-experiment study of therapeutic intervention was carried out in 21 patients with zoster herpes. They were assisted in the Physical Medicine Service of the MININT Polyclinic in Santiago de Cuba, from January, 2016 to June, 2017. Two groups were conformed at random: the members of the first one received acyclovir, vitamins and lasertherapy (intervention); those of the second group received acyclovir, vitamins and analgesic (control). Results: It was observed that in the intervention group the intensity of the pain was diminishing in connection with the initial evaluation. This way, in the fifth session it was appreciated a higher percentage of patients with pain relief that in the control group, the same as in the tenth session and 21 days later, hence the effectiveness of the treatment. Conclusions: With the use of low power laser the patients with zoster herpes presented an improvement of the pain in less time, with a satisfactory response expressed in all of them, reason why its use is recommended as adjuvant therapy.

With the increase of age or the impairment of immune function, the specific cellular immune level against varicella zoster virus (VZV) in the body decreases, and the latent VZV in the ganglion can be reactivated to cause herpes zoster (HZ). HZ and its main complication postherpetic neuralgia (PHN) can seriously affect the quality of life of patients. The immunocompromised (IC) population is more prone to HZ than the immunocompetent population due to diseases and therapeutic drugs. This paper reviews the incidence, risk factor and economic burden of HZ in IC population with special health status, to provide ideas for research and adjustment of immunization strategies in the future.

Objective: To determine the knowledge of influenza, pneumonia, herpes zoster and related vaccines, willingness to vaccinate under multiple payment scenarios, and corresponding risk factors among people over 50 years old in Minhang District of Shanghai. Methods: A total of 1 672 respondents aged 50-69 from 13 communities/towns in Minhang district of Shanghai were included in this study using a stratified random sampling strategy on December 2020. The knowledge of influenza, pneumonia, herpes zoster and vaccines was investigated using a questionnaire, and the differences in the willingness under multiple payment scenarios were determined using chi-square test. The consistency in the willingness under multiple payment scenarios was compared using Cohen's Kappa and the risk factors of the willingness was determined using ordinal logistic regression. Results: The average age of 1 672 respondents was (60.48±5.96) years old, including 777 (46.47%) males and 895 (53.53%) females. A total of 1 350 subjects (80.74%) had local household registration in Shanghai. The proportion of the willingness to vaccinate for themselves, spouses, and parents under any payment scenario was determined to be 80.6% (influenza vaccine), 81.5% (pneumonia vaccine), and 74.0% (herpes zoster vaccine). The willingness to vaccinate against influenza and pneumonia under multiple payment scenarios remained stable (Kappa value ≥0.6), while that against herpes zoster infection was inconsistent (Kappa value ≤0.35). Logistic regression analysis showed that respondents who had higher knowledge of influenza and influenza vaccine [OR (95%CI): 1.111 (1.054-1.170), 1.182 (1.126-1.240), respectively], aged 50-59 [1.305 (1.085-1.531)] and local household registration in Shanghai [1.372 (1.079-1.721)] had higher willingness to vaccinate against influenza, while males had lower willingness [0.733 (0.551-0.910)]. Respondents who had higher knowledge of pneumonia and pneumonia vaccine [OR (95%CI): 1.837 (1.152-2.517), 2.217 (1.541-2.893), respectively] had higher willingness to receive pneumonia vaccine. Respondents aged 50-59 [1.327 (1.059-1.537)] and with local household registration in Shanghai [2.497 (1.417-4.400)] were more likely to be vaccinated against herpes zoster, while those with middle school degree or below [0.664 (0.396-0.992)] and high school degree [0.559 (0.324-0.964)] were less likely to be vaccinated. Conclusion: Among people aged over 50 years old in Minhang district of Shanghai, the willingness to vaccinate for themselves, spouses, and parents against influenza, pneumonia and herpes zoster infection is quite different under multiple payment scenarios, especially for herpes zoster vaccine.

Objective: To understand the incidence and economic burden of herpes zoster among the aged in Laiwu district, Jinan city. Methods: Retrospective cohort study was conducted in 5 communities in Laiwu District, Jinan City from July to September, 2019. A total of 8 300 residents born before July 1, 1959 and aged ≥60 years old were included in the investigation. At the same time, an economic burden survey was carried out among 220 cases who developed herpes zoster after July 1, 2017. A questionnaire was used to collect information on incidence and economic burden of HZ, and comparisons were carried out about the incidence and economic burden of herpes zoster among older people with different characteristics. Results: The age of 8 300 subjects was (71.46±6.71) years old. Male and female accounted for 44.10% and 55.90%, respectively. The cumulative incidence of disease after the age of 60 was 73.61‰ among population aged ≥60 years old. The cumulative incidence was 28.03‰, 71.26‰, 86.09‰, 93.48‰ and 88.10‰ among population aged 60-64, 65-69, 70-74, 75-79 and ≥80 years old,respectively. The average annual incidence of HZ was 9.49‰ and annual incidence was 7.59‰, 7.23‰, 8.43‰, 10.24‰ and 13.98‰ in 2014-2018, respectively. HZ cost was (2 626±667) RMB per patient with a median cost of 715 RMB (interquartile range 303-2 358) on 220 cases who developed disease after July 1, 2017. The cost of outpatient cases was (1 329±1 835) RMB per patient with a median cost of 560 RMB (interquartile range 300-1 320), and the cost of inpatient cases was (14 303±16 571) RMB per patient with a median cost of 8 190 RMB (interquartile range 4 368-15 160). Conclusion: The incidence of HZ is high among population aged≥60 years old, which could cause heavy economic burden for them.

BACKGROUND@#We investigated whether family histories of herpes zoster (HZ) are associated with the risk of incident HZ in a Japanese population.@*METHODS@#A total of 12,522 Japanese residents aged ≥50 years in Shozu County participated in the baseline survey between December 2008 and November 2009 (the participation rate = 72.3%). They were interviewed at baseline by research physicians regarding the registrants' history of HZ. A self-administered questionnaire survey was conducted to evaluate the potential confounding factors. 10,530 participants without a history of HZ were followed up to ascertain the incidence of HZ during 3-years follow-up until the end of November 2012 with Japanese nationals. We estimated hazard ratios (HRs) of incident HZ according to first-degree family histories using the Cox proportional hazard regression after adjusting for age, sex, and other potential confounding factors.@*RESULTS@#Compared to no HZ history of each family member, a history of brother or sister was associated with a higher risk of incident HZ while histories of father and mother were not. The multivariable HR (95%CI) of incident HZ for a history of brother or sister was 1.67 (1.04-2.69). When comparing to no family histories of all first-degree relatives, the multivariable HRs (95%CIs) were 1.34 (0.77-2.34) for a history of brother or sister alone, but 4.81 (1.78-13.00) for a history of mother plus brother or sister. As for the number of family histories, the multivariable HRs (95%CIs) were 1.08 (0.76-1.54) for one relative (father, mother, or brother or sister) and 2.75 (1.13-6.70) for two or more relatives.@*CONCLUSION@#Family histories of mother plus brother or sister and two or more first-degree relatives were associated with a higher risk of incident HZ.

Objective: To investigate the genetic characteristics of varicella zoster virus (VZV) in Shandong province from 2020 to 2021. Methods: From April 2020 to December 2021, 85 herpes fluid samples from suspected varicella patients in Shandong province were collected. The qPCR was used to detect viral DNA and screen suspected samples. Six single nucleotide polymorphisms (SNPs) of ORF22 fragment and ORF38 fragment in positive samples were examined via PCR and Sanger sequencing to identify the viral genotypes. Four SNPs of ORF38 and ORF62 were examined to identify the vaccine and wild-type strains. The sequences were analyzed with Sequencher and MEGA7 software, using the VZV reference strain sequences from GenBank. Results: In the 85 samples suspected of varicella, 80 were VZV positive and wild-type strains belonging to Clade 2. Compared with clade 2 representative strains, the nucleotide and amino acid similarities of ORF22 fragment were 99.5%-100% and 98.5%-100%, respectively. SD20-1, SD20-5, SD20-6, SD20-8, SD20-9, SD20-10, SD20-11, SD20-12, SD20-13, SD20-30 and SD20-31 had a A➝G nucleotide mutation at 37990, causing amino acid change from glutamine to arginine. SD21-1 had a C➝A nucleotide mutation at 38059, causing threonine to asparagine during coding. Conclusions: From 2020 to 2021, all VZV strains in Shandong province are the wild-type strains belonging to Clade 2.

Introdução: A infecção viral causada pelo HSV-1 leva ao aparecimento das lesões do herpes simples e é caracterizada por períodos de infecção primária, latência e recorrência. Durante a vida do indivíduo esta infecção pode ser reativada por diversos fatores como o estresse. No contexto pandêmico de COVID-19, observa-se um aumento de efeitos psicológicos negativos derivados da exaustão emocional entre os estudantes universitários. Objetivo: Avaliar a relação entre o estresse e a recorrência de lesões do herpes simples bucal durante a pandemia de COVID-19 nos estudantes de graduação em odontologia. Materiais e Métodos: Este estudo observacional, descritivo, transversal e de abordagem quali-quantitativo, foi realizado com uma população constituída por 347 estudantes de odontologia, maiores de 18 anos independente de gênero e cor da pele, que já apresentaram episódios primários e/ou recorrentes de herpes simples bucal antes da pandemia de COVID-19. Foram excluídos os estudantes matriculados em odontologia que se recusaram a concordar com o termo de consentimento livre e esclarecido (TCLE). Resultados: A maioria dos participantes era do gênero feminino (81%) com idade entre 20 e 23 anos. Somente 8% apresentaram recorrência das lesões do herpes simples durante o período pandêmico. Entre eles, 78% apresentaram 1 vez, 11% indicaram 4 vezes e 11% revelaram 5 vezes. Analisou-se o nível de estresse, ansiedade e depressão dos participantes por meio da escala DASS-21 e observou-se que entre os colaboradores que apresentaram recorrência do herpes simples bucal, 44% apresentavam ansiedade grave. Ademais, 44% dos participantes manifestaram nível grave e outros 44% nível moderado de estresse. Conclusão: O estudo mostrou o impacto negativo que o período da pandemia de COVID-19 tem causado nos estudantes de odontologia. Notou-se que a parcela da população que apresentou a recorrência das manifestações do vírus em grande maioria indicou ansiedade no nível grave e estresse nos níveis moderado e grave.

Introduction: The viral infection caused by HSV-1 leads to manifestation of herpes simplex lesions and is characterized by periods of primary infection, latency and recurrence. During the individual's life, this infection can be reactivated by several factors such as stress. In the COVID-19 pandemic context, an increase in negative psychological effects derived from emotional exhaustion among university students is observed. Objective: To evaluate the relationship between stress and recurrence of oral herpes simplex lesions during the COVID-19 pandemic in undergraduate dentistry students. Materials and Methods: This observational, descriptive, cross-sectional study, with a quali-quantitative approach, was carried out with a population consisting of 347 dentistry students, over 18 years old, regardless of gender and skin color, who had already had primary episodes and/or recurrent oral herpes simplex before the COVID-19 pandemic. Students enrolled in Dentistry who refused to agree to the free and informed consent form (ICF) were excluded. Results: Most participants were female (81%), aged between 20 and 23 years. Only 8% had recurrence of herpes simplex lesions during the pandemic period. Among them, 78% presented 1 time, 11% indicated 4 times and 11% revealed 5 times. The level of stress, anxiety and depression of the participants was analyzed using the DASS-21 scale and it was observed that among the collaborators who presented recurrence of oral herpes simplex, 44% had severe anxiety. Besides, 44% of participants expressed a severe level and another 44% moderate level of stress. Conclusion: The study showed the negative impact that the period of the COVID-19 pandemic has caused in dentistry students. It was noted that the portion of thepopulation that presented the recurrence of the manifestations of the virus in the vast majority indicated severe level anxiety and stress at moderate and severe levels

Resumen | Como los otros herpesvirus alfa, el virus de la varicela-zóster (VZV) permanece en estado de latencia en los ganglios neurales después de la infección primaria (varicela). La reactivación de una infección latente por VZV en los ganglios de la raíz dorsal, produce el herpes zóster. La erupción que este provoca se caracteriza por lesiones cutáneas metaméricas que se acompañan de dolor neurítico y comprometen con mayor frecuencia a ancianos y sujetos inmunocomprometidos, en especial, aquellos infectados con el virus de la inmunodeficiencia humana (HIV). Las complicaciones que se observan en esta población de pacientes incluyen neumonía, hepatitis y compromiso del sistema nervioso central (meningitis y encefalitis). Varios síndromes clínicos se asocian con el herpes zóster de localización craneal, incluida la parálisis facial periférica y el síndrome de Ramsay-Hunt, el cual constituye la segunda causa de parálisis facial periférica y tiene una gran variedad de presentaciones clínicas. La parálisis facial se presenta en 60 a 90 % de los casos de síndrome de Ramsay-Hunt, puede preceder o aparecer después de las lesiones cutáneas y tiene peor pronóstico que la parálisis de Bell. Se describen aquí dos casos de herpes zóster del ganglio geniculado, con parálisis facial periférica que coincidió con la aparición de las lesiones cutáneas vesiculosas en el conducto auditivo externo y el pabellón auricular (síndrome de Ramsay-Hunt multimetamérico). En ambos casos, se identificó el genoma del VZV mediante PCR en el líquido cefalorraquídeo (LCR).

Abstract | Like other alpha-herpesviruses, the varicella-zoster virus (VZV) remains latent in the neural ganglia following the primary varicella infection. The reactivation of the VZV in the dorsal root ganglia results in herpes zoster. Herpes zoster eruption is characterized by localized cutaneous lesions and neuralgic pain mostly in older and immunocompromised persons, especially those living with the human immunodeficiency virus (HIV). The most commonly reported complications include VZV pneumonia, meningitis, encephalitis, and hepatitis. Several neurologic syndromes have been described associated with herpes zoster localized in cranial areas including peripheral nerve palsies and the Ramsay-Hunt syndrome, which has a varied clinical presentation and is the second most common cause of peripheral facial paralysis. Facial paralysis in this syndrome occurs in 60 to 90% of cases and it may precede or appear after the cutaneous lesions with a worse prognosis than idiopathic Bell paralysis. Here we present two cases of herpes zoster from the geniculate ganglia with peripheral facial paralysis that appeared simultaneously with vesicular herpetic otic lesions (multimetameric Ramsay-Hunt syndrome). In the two cases, amplifiable varicella-zoster viral DNA was found in the cerebrospinal fluid by RT-PCR Multiplex.

RESUMEN El herpes zóster es una afección infrecuente en lactantes, con una incidencia de 0,74/1 000 habitantes. Se produce por la reactivación del virus de la varicela zóster, tras una primoinfección por varicela. Puede ocurrir intraútero, por lo que resulta relevante conocer los antecedentes maternos. El diagnóstico es clínico y si se realiza de forma adecuada reduce el riesgo de complicaciones. El tratamiento en los niños es sintomático, porque su evolución es más favorable que en los adultos. Debido a la rareza de esta entidad, se presentan tres casos de herpes zóster en lactantes de 4, 6 y 11 meses de edad, que acudieron con lesiones y evolución típica de esta enfermedad al Hospital Pediátrico Provincial Docente Eliseo Noel Caamaño, de Matanzas, entre septiembre y octubre de 2017 (AU).

ABSTRACT Herpes zoster is an uncommon affection in infants, with an incidence of 0.74/1 000 inhabitants. It is produced by the reactivation of the varicella-zoster virus, after a primary infection by varicella. This can occur inside the uterus, making it relevant to know maternal antecedents. The diagnosis is clinical, and if it is made in an appropriate way, reduces complication risk. The treatment in children is symptomatic because its evolution is more favorable than in adults. Due to the rareness of this entity, we present three cases of herpes zoster in nurslings aged 4, 6 and 11 moths who assisted the Teaching Pediatric Hospital Eliseo Noel Caamaño, of Matanzas, with lesions and typical evolution of this disease in the period September-October 2017 (AU).

Abstract A 56-year-old male, HIV-positive, presented with a 3-day history of multiple indurated erythematous nodules with superficial and well-defined erosions on his right gluteus. Skin biopsy showed ballooning-necrotic keratinocytes and cultures were positive for herpes simplex 2. Genital herpes simplex infection recurrences may not be restricted to the anterior part of the genitalia and clinical presentation in the lumbar area or gluteus must be differentiated from varicella-zoster virus infection. Tumor-like presentation is a very rare manifestation of HSV cutaneous infection. It is important to take this morphological variant into consideration not to delay the diagnosis of a viral infection, especially in an immunosuppressed patient.

Introduction: Streptococcus mutans is involved in the genesis and progress of dental caries, one of the most prevalent diseases worldwide, whose control requires safe methods accessible to the population. Myrciaria dubia (Kunth) McVaugh (Myrtaceae) (camu camu) is a tree native to the Peruvian Amazon. The antimicrobial capacity of the components of its fruit has already been verified. Objective: Evaluate the in vitro antibacterial activity of M. dubia hydroethanolic extract against S. mutans ATCC 35658. Methods: An experimental study was conducted with post-test analysis and control groups. The extract from the pulp of the fruit of M. dubia was obtained by hydroethanolic maceration. The concentrations evaluated were 25 mg/mL, 50 mg/mL and 75 mg/mL. Antibacterial capacity was determined by the disc diffusion method. The positive control was 0.12 percent chlorhexidine gluconate, whereas the negative control was 1 percent dimethyl sulfoxide. Results: The antibacterial activity increased directly proportional to the concentration of the extract. The concentration of 75 mg/mL showed a mean inhibition of 18.2 ± 0.774 mm, followed by the concentration of 50 mg/mL with a mean inhibition of 14.6 ± 1.055 mm and the concentration of 25 mg/mL with an average inhibition halo of 10.1 ± 0.833 mm. The zone of inhibition of the positive control was 16.5 ± 0.516 mm. There is a statistically significant difference between the concentration of 75 mg / mL and the positive control (p< 0.05). Conclusions: The M. dubia hydroethanolic extract displays in vitro antibacterial bactericidal activity against S. mutans ATCC 35668(AU)

Objetivo: Presentar un caso clínico en el que el paciente cursa impétigo que podría estar relacionado con el uso de mascarillas faciales por un tiempo prolongado. Caso clínico: Se reporta el tratamiento y la evolución de un caso clínico en un paciente adulto que consultó en un centro clínico privado por la presencia de lesiones vesiculares en la región labial superior con aumento de volumen generalizado en ambos labios. El cuadro clínico es compatible con infección por impétigo y herpes zóster asociado al uso prolongado de una mascarilla de tela. Se describe la importancia del empleo correcto de estas mascarillas que se están usando como medida de protección personal en el contexto de la pandemia por COVID-19, ya que las mismas pueden contribuir a generar infecciones faciales si no se mantiene una higiene apropiada (AU)

Aim: To present a clinical case in which the patient has impetigo that could be related to the use of facial masks for a long time. Clinical case: The treatment and evolution of a clinical case of an adult patient who attended a private clinical centre due to the presence of vesicular lesions in the upper labial region with generalized increase volume in both lips is reported. The clinical presentation is compatible with impetigo and herpes zoster infection associated with prolonged use of a cloth mask. The importance of the correct use of cloth masks that are being used as a personal protection measure in the context of the COVID-19 pandemic is described, since they can contribute to facial infections if proper hygiene is not observed (AU))

Resumen Los estreptococos del grupo Streptococcus anginosus (EGA) son colonizantes habituales de las mucosas orofaríngea, intestinal y genitourinaria, pero, cada vez más frecuentemente, son reconocidos como patógenos humanos. En esta parte IIIa se describen la epidemiología de las infecciones por EGA y las características de las localizadas en cabeza y cuello. Es ampliamente conocida su capacidad de formar abscesos; en particular en la zona de cabeza y cuello se destacan los abscesos odontogénicos, los periorbitales y los cerebrales. También producen sinusitis, infecciones oculares, abscesos epidurales, síndrome de Lemierre, empiemas subdurales y colecciones en piel y tejidos blandos y huesos del cráneo. Su rol en la faringitis es controvertido aunque algunas de las subespecies podrían estar involucradas en ese tipo de infecciones. También se postula su potencial cancerígeno dada su asociación con carcinomas orofaríngeos, gástricos o esofágicos.

Abstract Streptococcus anginosus group (SAG) organisms are common colonizers of the oropharyngeal, intestinal, and genitourinary mucosa, but are increasingly recognized as human pathogens. This part IIIa describes the epidemiology of SAG infections and the characteristics of those located in the head and neck. Its ability to form abscesses is widely known, particularly, in the head and neck area; odontogenic, periorbital and brain abscesses stand out. They also cause sinusitis, eye infections, epidural abscesses, Lemierre's syndrome, subdural empyemas, and collections in the skin and soft tissues and bones of the skull. Its role in pharyngitis is controversial, although some of the subspecies could be involved in such infections. Its carcinogenic potential is also postulated given its association with oropharyngeal, gastric or esophageal carcinomas..

Resumo Os estreptococos do grupo Streptococcus anginosus (EGA) são colonizadores comuns da mucosa orofaríngea, intestinal e geniturinária, mas são cada vez mais frequentemente reconhecidos como patógenos humanos. Esta parte IIIa descreve a epidemiologia das infecções por EGA e as características daquelas localizadas na cabeça e no pescoço. Sua capacidade de formar abscessos é amplamente conhecida, principalmente, na região da cabeça e pescoço, destacando-se os abscessos odontogênicos, os periorbitais e os cerebrais. Eles também causam sinusite, infecções oculares, abscessos epidurais, síndrome de Lemierre, empiemas subdurais e coleções em pele e tecidos moles, e ossos do crânio. Seu papel na faringite é controverso, embora algumas das subespécies possam estar envolvidas em tais infecções. Seu potencial carcinogênico também é postulado pela associação com carcinomas orofaríngeos, gástricos ou esofágicos.
