Chickenpox in varicella IgG positive patients: experience of a regional paediatric oncology centre.

Aciclovir prophylaxis was previously given to all immunocompromised patients treated by our unit, following contact with varicella zoster. In 2003, we changed practice according to National Guidelines, giving prophylaxis only to patients without serum varicella zoster immunoglobulin G antibody (VZ IgG) at diagnosis of their malignancy. Since then we have seen nine patients with acute lymphoblastic leukaemia (ALL) and VZ IgG positivity at diagnosis of their malignancy develop chickenpox. Our observations question current practice for patients with ALL.

[Epidemiological analysis of immunity against vaccine-preventable diseases: rubella, measles, mumps and chickenpox].

BACKGROUND AND OBJECTIVE: Measles, mumps, rubella and varicella zoster virus (VZV) infections are regarded as typical diseases of childhood: They are normally clinically mild and result in lifelong immunity. Severe clinical disease is known in immunocompromised patients; rubella virus infections during pregnancy often result in congenital rubella syndrome. All these diseases are preventable by vaccination which is recommended in Germany, recently vaccination against VZV for teenager without immunity since July 2001. In the following study we screened for immunity against the four viruses. PAT

Malignant disease in children whose mothers had chickenpox, mumps, or rubella in pregnancy.

To test the hypothesis that leukaemia may follow virus infection in pregnancy an analysis was made of deaths which occurred in a cohort of children born in 1951 and 1952 after pregnancies in which the mothers suffered virus infections-chickenpox or mumps at any stage of gestation or rubella in the first 18 weeks. All deaths which occurred between the children's second birthday and the end of 1971 were studied.Two deaths from leukaemia occurred among the children whose mothers suffered from chickenpox, a significant excess. There were no deaths from leukaemia among the other children, but the c…

A numerical treatment through Bayesian regularization neural network for the chickenpox disease model.

OBJECTIVES: The current research investigations designates the numerical solutions of the chickenpox disease model by applying a proficient optimization framework based on the artificial neural network. The mathematical form of the chickenpox disease model is divided into different categories of individuals, susceptible, vaccinated, infected, exposed, recovered, and infected with/without complications. METHOD: The construction of neural network is performed by using the single hidden layer and the optimization of Bayesian regularization. A dataset is assembled using the explicit Runge-Kutta t…

Как провести различие между кожной сыпью и кожей, мононуклеозом, ветрянкой, шестым заболеванием и корью.

ЦЕЛЬ ОБЗОРА: сыпь кожи, наблюдаемая в период COVID-19, обычно включает в себя макулопапулярную или сосудистую морфологию, имитируя таким образом резиновые извержения, происходящие в других распространенных инфекционных дерматозах, таких, как мононуклеоз, ветрянка, шестая болезнь и корь, с возможными диагностическими ошибками. В этой обзорной статье мы пытались представить практический обзор клинического характера сыпей кожи, связанных с инфекцией SARS-COV-2. ПОСЛЕДНИЕ ФИННДИНЫ: В исследовании резюмируются литературные данные о клинических схемах, связанных с COVID-19 и связанных с сосудистой с

PURPOSE OF REVIEW: Skin rashes seen during COVID-19 usually feature maculopapular or vesicular morphology, thus mimicking cutaneous eruptions occurring in other common infectious dermatoses, such as mononucleosis, chickenpox, sixth disease and measles, with possible diagnostic mistakes. In this review article, we sought to provide a practical overview about …

[Chickenpox and shingles: one virus, two diseases and current vaccination recommendations in Switzerland].

Adults, pregnant women, premature babies and immunocompromised persons are at increased risk for varicella complications. Therefore the current Swiss vaccination recommendations against varicella include a general recommendation for 11 to 15 year old adolescents with a negative varicella history, as well as a specific recommendation for risk groups. The goal of both recommendations is to reduce varicella complications in persons most at risk. The vaccine is not universally recommended for all toddlers in Switzerland, while this is the case in some countries such as the United States. Pros and

Multifocal bacterial osteomyelitis after varicella infection: a rare but dreaded complication of chickenpox.

Chickenpox is an infectious disease common in children, which in most cases is benign toward the self-limited resolution. There are, however, serious systemic and musculoskeletal complications, especially in patients with immunosuppression. We report a case of multifocal skeletal muscle involvement, as a complication of chickenpox by Streptococcus pyogenes.

Chickenpox is not always benign: postvaricella purpura fulminans requires prompt and aggressive treatment.

We present 2 patients, who were admitted owing to rapidly progressing purpuric lesions due to postvaricella purpura fulminans, a coagulopath … tions. Therefore, we should be reminded that purpura fulminans is a rare but severe complication of chickenpox, which demands quick action.

Growth, morbidity and mortality after chickenpox infection in young children in Guinea-Bissau.

OBJECTIVE: To examine whether chickenpox in children below 2 years of age is associated with post-infection changes in growth, morbidity or mortality. METHODS: An outbreak of chickenpox was investigated in Guinea-Bissau. An examination, interview and anthropometry were performed 6 months after the epidemic for a group of children and matched controls whose weight had been measured at the time of the chickenpox episode. All children diagnosed with chickenpox before 2 years of age were followed for survival and hospitalisations to the age of 3 years and compared with all other children in the c…

Incidence of Secondary Skin Infections in Children Affected with Chickenpox: A Prospective Observational Study.

BACKGROUND: Chickenpox (varicella) is a common childhood viral illness that is usually self-limiting; however, it may be complicated by secondary bacterial skin infections, particularly in pediatric populations. These secondary infections contribute significantly to morbidity, prolonged hospital stays, and increased healthcare utilization. The present study aims to determine the incidence of secondary skin infections among children affected with chickenpox and to identify associated risk factors. METHODOLOGY: A descriptive observational study was conducted among children diagnosed with chicke…

Burden of chickenpox complications in Poland, 2006 to 2021: A comprehensive registry-based study.

BackgroundChickenpox, a vaccine-preventable disease caused by the varicella zoster virus, generally presents with mild symptoms but can cause complications necessitating hospitalisation. In Poland, since 2009, vaccination has been obligatory for children up to 12 years of age who are particularly vulnerable to infection and for children in their vicinity.AimTo examine the burden of chickenpox complications and the trends of hospitalisation arising from these complications over time in the Polish population.MethodsData spanning 2006-21 were sourced from the Polish Infectious Diseases Surveillan…

Comparison of human monkeypox, chickenpox and smallpox: a comprehensive review of pathology and dermatological manifestations.

Variola virus, the causing agent of smallpox, was eradicated in 1980s and today no new cases are reported. The first human infectious illness to be eliminated globally is variola. On the contrary to Variola, monkeypox, which is a zoonotic and variola-like disease, has nowadays turned to be a major health problem worldwide. VZV is a neurotropic virus and the cause of varicella (chickenpox) and herpes zoster (shingles), which is also a highly infectious disease, especially prevalent in children. These three skin diseases-monkeypox, smallpox, and chickenpox-are frequently mistaken with one anothe…

Role of temperature in reported chickenpox cases in northern European countries: Denmark and Finland.

OBJECTIVE: In this study, we sought to explore the temperature-dependent transition of patterns of reported chickenpox cases in the northern European countries of Denmark and Finland to help determine the potential relationship with epidemiological factors of the disease. We performed time-series analysis consisting of a spectral analysis based on the maximum entropy method in the frequency domain and the nonlinear least squares method in the time domain, using the following time-series data: monthly data of reported chickenpox cases and mean temperatures in the pre-vaccination era for Denmark…

Role of meteorological conditions in reported chickenpox cases in Wuhan and Hong Kong, China.

BACKGROUND: Chickenpox is a common contagious disease that remains an important public health issue worldwide. Over 90% of unvaccinated individuals become infected, but infection occurs at different ages in different parts of the world. Many people have been infected by 20 to 30 years of age in China, and adults and pregnant women who become infected often develop severe infection. Furthermore, a mortality rate of 2-3 per 100,000 infected persons has been reported. In this study, we explore the temperature-dependent transition of patterns of reported chickenpox cases in two large subtropical c…

Spatio-temporal cluster detection of chickenpox in Valencia, Spain in the period 2008-2012.

Chickenpox is a highly contagious airborne disease caused by Varicella zoster, which affects nearly all non-immune children worldwide with an annual incidence estimated at 80-90 million cases. To analyze the spatiotemporal pattern of the chickenpox incidence in the city of Valencia, Spain two complementary statistical approaches were used. First, we evaluated the existence of clusters and spatio-temporal interaction; secondly, we used this information to find the locations of the spatio-temporal clusters via the space-time permutation model. The first method used detects any aggregation in our…
