Central Nervous System Complications of Varicella-Zoster Virus
Conclusion: Neurologic complications of VZV infection continue to occur despite the availability of an effective vaccine. Neurologic symptom onset can predate the appearance of the VZV exanthem and in rare cases may occur in the absence of an exanthem.

Assessment of pre-specified adverse events following varicella vaccine: A population-based self-controlled risk interval study.
CONCLUSIONS: We detected a small risk of incidental pneumonia associated with varicella vaccine in the 6th week after immunization. There was no increase in the risk of other pre-specified adverse events. PMID: 32046891 [PubMed - as supplied by publisher]

One-Third of COVID-19 Survivors May Develop a Neuropsychiatric Disorder Within Months of Infection
One-third of individuals diagnosed with COVID-19 developed a psychiatric or neurological problem within six months of their diagnosis, according to astudy published Tuesday inThe Lancet Psychiatry. The prevalence of a post-COVID neurologic or psychiatric diagnosis was even greater among individuals with severe illness who had required hospitalization.“Given the size of the pandemic and the chronicity of many of the diagnoses and their consequences (for example, dementia, stroke, and intracranial hemorrhage), substantial effects on health and social care systems are likely to occur,” wrote Maxime Taque, Ph.D., of the Un...

Changes in incidence rates of outcomes of interest in vaccine safety studies during the COVID-19 pandemic
CONCLUSION: Rates of some clinical outcomes during the pandemic changed and should not be used as historical background rates in vaccine safety studies. Inclusion of telehealth visits should be considered for vaccine studies involving Bell's palsy, ITP, and narcolepsy/cataplexy.PMID:35465977 | DOI:10.1016/j.vaccine.2022.04.037

Safety of diphtheria, tetanus, acellular pertussis and inactivated poliovirus (DTaP-IPV) vaccine.
CONCLUSIONS: In this safety surveillance study of more than 200,000 DTaP-IPV vaccine recipients, there was no evidence of increased risk for any of the pre-specified adverse events monitored. Continued surveillance of DTaP-IPV vaccine safety may be warranted to monitor for rare adverse events, such as Guillain-Barré syndrome. PMID: 24699471 [PubMed - as supplied by publisher]

Progress in pediatrics in 2015: choices in allergy, endocrinology, gastroenterology, genetics, haematology, infectious diseases, neonatology, nephrology, neurology, nutrition, oncology and pulmonology
AbstractThis review focuses key advances in different pediatric fields that were published in Italian Journal of Pediatrics and in international journals in 2015. Weaning studies continue to show promise for preventing food allergy. New diagnostic tools are available for identifying the allergic origin of allergic-like symptoms. Advances have been reported in obesity, short stature and autoimmune endocrine disorders. New molecules are offered to reduce weight gain and insulin-resistance in obese children. Regional investigations may provide suggestions for preventing short stature. Epidemiological studies have evidenced th...

What Causes Microcephaly?
Discussion Microcephaly is usually defined as an occipitofrontal head circumference (OFC) more than 2 standard deviations (SD) below the mean for sex, age and ethnicity. Severe microcephaly is used for OFC < 3 standard deviations. Rates of microcephaly range from 0.5-12 patients/10,000 live births. The OFC should be measured at every well child visit and at other opportunities and plotted on standard growth charts. The OFC is measured using a nonelastic tape measure around the largest part of the head with the tape measure held above the eyebrows and ears. It is a highly reproducible measurement. There are several diff...

Severe chickenpox disease and seroprevalence in Sweden – implications for general vaccination
Chickenpox is the clinical manifestation of primary infection with varicella zoster virus (VZV) and a mild disease in the vast majority of cases. However, complications occur, primarily bacterial infections of vesicles, sometimes with deeper infection and sepsis, as well as neurological complications; e.g. encephalitis, meningitis, or classically acute cerebellitis with ataxia. Rare complications such as pneumonitis, hepatitis and haemorrhagic complications may occur (Gershon et al., 2018). There is even an increased risk of stroke in the time period 6 months after a chickenpox episode (Thomas et al., 2014).

Neuro ‐COVID‐19
AbstractNeuromuscular manifestations of new coronavirus infection (COVID-19) are frequent and include dizziness, headache, myopathy, and olfactory and gustatory disturbances. Patients with acute central nervous system (CNS) disorders, such as delirium, impaired consciousness, stroke, and convulsive seizures, have a high mortality rate. The encephalitis/encephalopathy that causes consciousness disturbance and seizures can be classified into three conditions, including direct infection with the SARS-CoV-2 virus, encephalopathy caused by CNS damage secondary to systemic hypercytokinemia (cytokine storm), and autoimmune-mediat...

Neurological disorders seen during second wave of SARS-CoV-2 pandemic from two tertiary care centers in central and Southern Kerala
Conclusion: During the SARS-CoV-2 pandemic, CAND and PVND have been emerging. Association of some of these may be fortuitous; however it is worth mentioning as pathogenic mechanisms of COVID-19 affecting various organ systems still remain unclear. Moreover, this may be helpful in future studies designing management options.

Neurological toll of COVID-19
AbstractThe first case of coronavirus illness was discovered in Wuhan, China, in January 2020 and quickly spread worldwide within the next couple of months. The condition was initially only linked with respiratory disorders. After the evolution of various variants of the SARS-CoV-2, the critical impact of the virus spread to multiple organs and soon, neurological disorder manifestations started to appear in the infected patients. The review is focused on the manifestation of various neurological disorders linked with both the central nervous system and peripheral nervous system. Disorders such as cytokine release syndrome,...

Neurological Effects of Monkeypox Largely Unknown, Review Finds
Much remains unknown about the long-term neurologic effects of monkeypox. In anarticle published today inJAMA Neurology, researchers from the National Institute of Neurological Disorders and Stroke (NINDS) and colleagues described how reports of complications from other orthopoxviruses, such as smallpox, may offer clues about the neurologic consequences of monkeypox.“Although the COVID-19 pandemic is the worst pandemic in a century, the recent past has seen several major pandemics, including Zika, Ebola, dengue, West Nile, and AIDS,” wrote B. Jeanne Billioux, M.D., of NINDS and colleagues. “A common thread to these p...
