Poliovirus (PV) is the causative agent of poliomyelitis, a crippling human disease known since antiquity. PV occurs in two distinct antigenic forms, D and C, of which only the D form elicits a robust neutralizing response. Developing a synthetically produced stabilized virus-like particle (sVLP)-based vaccine with D antigenicity, without the drawbacks of current vaccines, will be a major step towards the final eradication of poliovirus. Such a sVLP would retain the native antigenic conformation and the repetitive structure of the original virus particle, but lack infectious genomic material...

In Italy, in this period, much attention is dedicated to reach adequate vaccination coverage in children and adolescents. In this study, Vaccination Registry was checked in a Local Health Unit in Rome, Italy, to identify children born in 2007 and 2008 who had not completed the vaccination schedule. Coverage for booster doses of measles, mumps, rubella and for diphtheria, tetanus, pertussis and polio vaccines in the 2213 children was around 70%. A reminder letter was send to parents of the 661 incompletely immunized children and, if they did not reply, a phone call was made when the phone number was available...

BACKGROUND: Pakistan is one of the 3 remaining wild poliovirus endemic countries. We collected sera from children to assess the prevalence of poliovirus antibodies in selected high-risk areas for poliovirus transmission. METHODS: Children in 2 age groups (6-11 and 36-48 months) were randomly selected between November 2015 and March 2016 in 6 areas of Pakistan (Sindh Province: Karachi and Kashmore; Khyber Pakhtunkhwa Province: Peshawar, Bannu and Nowshera; Punjab Province: Faisalabad)...

Ensuring the sustained immunization of displaced persons is a key objective in humanitarian emergencies. Typically, humanitarian actors measure coverage of single vaccines following an immunization campaign; few measure routine coverage of all vaccines. We undertook household surveys of Syrian refugees in Jordan and Lebanon, outside of camps, using a mix of random and respondent-driven sampling, to measure coverage of all vaccinations included in the host country's vaccine schedule. We analyzed the results with a critical eye to data limitations and implications for similar studies...

BACKGROUND: New or increased impairments may develop several decades after an acute poliomyelitis infection. These new symptoms, commonly referred to as late effects of polio (LEoP), are characterised by muscular weakness and fatigue, generalised fatigue, pain at rest or during activities and cold intolerance. Growing older with LEoP may lead to increased activity limitations and participation restrictions, but there is limited knowledge of how these persons perceive the practical and psychological consequences of ageing with LEoP and what strategies they use in daily life...

OBJECTIVE: To explore how persons with late effects of polio experience falls and what strategies they use to manage the consequences of falls. DESIGN: A qualitative study with face-to-face interviews. Data were analysed by systematic text condensation. PARTICIPANTS: Fourteen ambulatory persons (7 women; mean age 70 years) with late effects of polio. RESULTS: Analysis resulted in one main theme, "Everyday life is a challenge to avoid the consequences of falls", and 3 categories with 7 subcategories...

Cancer is not a single disease. The term refers to literally hundreds of illnesses sharing common features: inappropriate proliferation of imperfectly differentiated cell types, invasion of nearby vital structures, and spread to distant sites (metastasis). Invasiveness and metastasis distinguish cancers from benign tumors such as fibroids and meningiomas. Yet, each type is distinct, possessed of defining morphologic, histologic, biochemical, and genomic features that have allowed oncologists to develop a nosology that guides diagnosis and therapy...

BACKGROUND: Poliomyelitis is a viral, nervous system disease that affects both the upper and the lower extremities. The treatment of severe coxarthrosis in these patients with total hip arthroplasty (THA) has been widely questioned because of the high risk of subsequent complications. The aim of the present study was to describe both radiological and medium term clinical results in a series of patients with post polio residual paralysis that underwent THA. MATERIALS AND METHODS: We report a retrospective review of a series of 5 five patients diagnosed with severe coxarthrosis secondary to post polio residual paralysis who were operated between 2008 and 2012...

Environmental surveillance of polioviruses has been used as an important tool in monitoring circulation of wild polioviruses and/or Vaccine derived polioviruses in sewage samples. It is important to distinguish Sabin like isolates from non-Sabin like; ELISA & dual stage real time RT-PCR have been used for the same. Current study was carried out on sewage isolates to compare ELISA & RT-PCR with sequencing to distinguish Sabin like from non-Sabin like. Out of 468 sewage specimens, 91 (19.44%) were non-polio enteroviruses positive and 377 (80...

This article investigates whether the United States' counterinsurgency operations have inhibited polio eradication efforts in northwestern Pakistan, the world's last major reservoir of polio. Anecdotal evidence suggests that militants disrupt polio vaccination programs because of suspicions that campaigns are a cover for gathering intelligence on Central Intelligence Agency (CIA) drone targets. This paper analyzes national-level quantitative data to test this argument. Between 2004 and 2012, the number of polio cases in Pakistan closely mirrored the number of drone strikes...

OBJECTIVE: Parental compliance is crucial to the success of mass vaccination campaigns targeting children. Relying on psychological/neuroscientific research concerning the role of personification (i.e., viewing the inanimate as human) in behavior, the authors examined the effect of parents' personification of the Israeli Ministry of Health (MoH) on compliance with a publicly controversial mass vaccination campaign, which was aimed at stopping the spread of a wild poliovirus. METHODS: Participants were 555 parents of children aged 9 or younger, residing in the center/north of Israel, an area covered by Phase 2 of the campaign...

BACKGROUND & OBJECTIVES: District-Level Household Survey-4 (DLHS-4) indicated that during 2012-2013, only 56 per cent of children aged 12-23 months in Tamil Nadu were fully vaccinated, which were lesser than those reported in earlier national surveys. We, therefore, conducted cluster surveys to estimate coverage of childhood vaccination in the State, and also to identify the factors associated with low coverage. METHODS: Cross-sectional surveys were conducted in 15 strata [municipal corporation non-slum (n=1), municipal corporation slum (n=1), hilly (n=1), rural (n=6) and urban (n=6)]...

BACKGROUND: More than 99% of poliovirus infections are non-paralytic and therefore, not detected by acute flaccid paralysis (AFP) surveillance. Environmental surveillance (ES) can detect circulating polioviruses from sewage without relying on clinical presentation. With extensive ES and continued circulation of polioviruses, Pakistan presents a unique opportunity to quantify the impact of ES as a supplement to AFP surveillance on overall completeness and timeliness of poliovirus detection...

Pakistan is at the verge of polio eradication but isolation of non-polio enteroviruses (NPEVs) from acute flaccid paralysis (AFP) cases may result in serious or even fatal outcome. Many enteroviruses share similar symptoms and epidemiology as is the case with poliovirus and coxsackievirus (CV). The present study was designed to genetically characterize coxsackievirus B (CV-B) serotypes isolated from non-polio acute flaccid paralytic children, as well as to understand their probable role in paralysis. A total of 63 (20·1%) out of 313 stool samples during 2013 were found positive for NPEVs in rhabdomyosarcoma cells...

In the Republic of Ireland, the schedule of state-funded immunisation for children is comprehensive and includes diphtheria, pertussis, tetanus, pneumococcus, hepatitis B, meningococcus C, haemophilus B, polio, measles, rubella and mumps. Varicella and meningococcal B vaccines are commercially available but are not currently funded by the government. Each of the illnesses preventable by these vaccines can cause substantial morbidity, and rarely mortality, in infants and children. Our PICU continues to see serious illness due to avoidable infection...

The work presented here demonstrates the utility of a two-step algorithm for environmental poliovirus surveillance based on: preselection of sewage samples tested for the presence of enteroviral genetic material-RT-PCR assay and detection of infectious viruses by cell culture technique (L20B for polioviruses and RD for polio and other non-polio enteroviruses). RD and L20B cell lines were tested to determine their sensitivity for isolation of viruses from environmental samples (sewage). Finally, we wanted to determine if sewage concentration affects the results obtained for RT-PCR and cell cultures...

Enteroviruses (EVs) are among viral pathogens that can cause acute flaccid paralysis (AFP). This study represents an overview of EVs isolated through AFP surveillance in Poland between 1999 and 2014. The presence of enteroviruses was studied in stool samples that were collected from 747 AFP cases and their asymptomatic contacts. Fifty five (6.12%) cases of AFP were associated with enterovirus isolation. Out of the 55 positive cases, 40 were associated with detection of enterovirus in patient, and 15 with detection of EV in healthy contact, without positive detection in paralytic patient...

Nearly all global health initiatives give per diems to community health workers (CHWs) in poor countries for short-term work on disease-specific programs. We interviewed CHWs, supervisors, and high-level officials (n = 95) in 6 study sites across sub-Saharan Africa and South Asia in early 2012 about the per diems given to them by the Global Polio Eradication Initiative. These per diems for CHWs ranged from $1.50 to $2.40 per day. International officials defended per diems for CHWs with an array of arguments, primarily that they were necessary to defray the expenses that workers incurred during campaigns...
