Aim: Analysis of the morbidity of vaccine-associated paralytic poliomyelitis and acute flaccid paralysis and the results of virological investigation of the patients on 14 territories of the Russian Federation in 1998-2017. Materials and methods: We investigated nearly 3000 stool samples from paralytic patients and contact persons. Isolation and identification of polioviruses were performed according to WHO recommendations with the help of cell lines RD and L20B. We conducted the sequencing of the genome fragments VP3-VP1, VP1-2A and full sequencing of genome region VP1 of 45 poliovirus strains. Results: From 1998 till 2017 1257 cases of acute flaccid paralysis were registered on 14 territories of Russia, 15 cases of which (1,2%) were classified as vaccine-associated paralytic poliomyelitis. From these patients 9 children were non vaccinated and 6 children received from one to four doses of oral poliomyelitis vaccine. The percentage of the detection of polioviruses from the patients and contact persons in different years was not equal and constituted from 3, 4±0,89% to 9, 5±0,79%. All in all from the patients with acute flaccid paralysis and contact persons we isolated 191 polioviruses, 60 of them belonged to type 1, 55 polioviruses were identified as types 2 and 76 as type 3. Some cases of vaccine-associated paralytic poliomyelitis are described in the article; polioviruses were isolated from all these patients. The sequencing of the genome fragments of 45 poliovirus strains showed that the majority of them had the nucleotide substitutions including neurovirulent substitutions. Conclusion: In order to prevent the risk of the appearance of vaccine-associated paralytic poliomyelitis it is necessary to maintain the high quality of surveillance of poliomyelitis and acute flaccid paralysis, to ensure the 95% coverage of children with poliomyelitis vaccine, to minimize the cases of groundless delays of vaccination according to medical recommendations and parents’ refusals to vaccinate children against poliomyelitis and to respect strictly the National calendar of vaccination.

Background: Acute flaccid paralysis (AFP) is defined by the acute onset of weakness or paralysis with reduced muscle tone in children. There are many non-infectious and infectious causes. Snake eye appearance (SEA) is a rare radiologic appearance and helps narrow down differential diagnoses in flaccid paralysis. Case Presentation: Here, we reported a 6 months-old girl who was admitted with sudden onset flaccid paralysis. She was lethargic and ill without any detectable deep tendon reflexes. She had a high fever that had started 3 days earlier with malaise, poor feeding and coryza. The first child of the family was a boy who expired with similar symptoms; however, the reason is still unknown. Her parents were relatives (cousins). The laboratory and cerebrospinal fluid tests analysis were normal. The brain MRI analysis revealed T1 dim Hypo intensity and T2 hyperintensity along with obvious ADC map hyperintensity in the brain stem. At first, the PCR tests analysis of stool samples for poliovirus and enterovirus were normal. Spinal MRI showed snake eye appearance and helped us narrow our differential diagnosis. We repeated the PCR tests of stool because of snake eye appearance in cervical MRI that was positive for poliovirus and indicated vaccine-associated Paralytic Poliomyelitis (VAPP). Unfortunately, she expired from vaccine associated poliomyelitis. Conclusion: Snake eye appearance is a rare radiologic appearance that can be seen in several pathological conditions; however, it is very rare in patients with acute flaccid paralysis. Radiology signs, especially in spinal cord MRI, can help recognizing abnormalities in images, and narrow the list of differential diagnosis in acute flaccid paralysis. Therefore, spinal cord MRI has an important role in the evaluation of patient with brain stem involvement in acute flaccid paralysis.

ABSTRACT BACKGROUND: Significant advances have been made in the global effort to eradicate polio. Vaccine-associated poliovirus, or other enteroviruses, may still affect the anterior horn cell and cause acute flaccid paralysis. Following the acute disease, residual paralysis results in lower motor neuron weakness, altered growth and deformity. Our study aims to describe the clinical manifestations of a group of children that mimic that of classic paralytic poliomyelitis METHODS: We identified six children from our paediatric orthopaedic database that presented with polio-like deformities. Their clinical and imaging records were reviewed and described, together with the clinical manifestations of paralytic poliomyelitis RESULTS: Limb hypoplasia, pathological gait patterns and foot deformities were consistent features. The median leg length discrepancy was 2.5 cm (range 2-4 cm). The gait patterns observed included a Trendelenburg gait in 33% (n=2), a short limb gait in 50% (n=3), and one case with a combination of Trendelenburg, short limb and steppage gait. Tensor fascia lata contracture was present in 50% (n=3) of our patients. Foot deformities ranged from calcaneo-cavo-valgus to equino-cavo-varus deformities CONCLUSION: Despite significant advances made in the global fight to eradicate polio, we still see children with clinical manifestations reminiscent of the disease. Orthopaedic surgeons should remain familiar with the assessment and diagnosis of the sequelae of paralytic poliomyelitis Level of evidence: Level 5 Keywords: poliomyelitis, vaccine-associated paralytic poliomyelitis, polio-like deformity, acute flaccid paralysis

Abstract Despite the elimination of indigenous wild poliovirus in Canada, ongoing surveillance for poliomyelitis is important because of the risk of wild virus importation from endemic regions. Most recently, importation of wild poliovirus into Canada occurred in 1993 and 1996,inboth instances with no associated clinical illness. Since 1991, the active surveillance of acute flaccid paralysis (AFP) in children less than 15 years old has been carried out in Canada to monitor for suspected cases of paralytic poliomyelitis. AFP surveillance is currently implemented through the Canadian Paediatric Surveillance Program. All suspected cases of paralytic poliomyelitis reported to the Laboratory Centre for Disease Control are evaluated by the national Working Group on Polio Eradication. The proper laboratory and neurological investigation of all AFP cases younger than 15 years old and suspected cases of poliomyelitis of any age is essential for the rapid detection of paralytic poliomyelitis, the most important clinical specimen for laboratory investigation being a stool sample collected within two weeks after the onset of paralysis for viral studies. This paper provides guidelines for investigating all suspected cases of paralytic poliomyelitis, including AFP cases less than 15 years old. Guidelines are also provided for reporting confirmed or suspected cases of paralytic poliomyelitis as well as the incidental finding of wild strain poliovirus, with or without any clinical symptoms.

ABSTRACT The Polio Endgame Strategy 2019–2023 has been developed. However, more effective and efficient surveillance activities should be conducted with the preparedness of emergence for vaccine-derived poliovirus (VDPV) or wild poliovirus (WPV). We reviewed the impact of the case-based acute flaccid paralysis (AFP) surveillance (1991 to 2018) and environmental surveillance (2011 to 2018) in polio eradication in Shandong province of China. Clinical characteristics of AFP cases and enterovirus (EV) investigation of research samples were assessed. During the period, 10,224 AFP cases were investigated, and 352 sewage samples were collected. The nonpolio AFP rate sustained at over 2.0/100,000 since 1997. Of 10,224 cases, males and young children experienced a higher risk of severe diseases, and 68.5% suffered lower limb paralysis. We collected 1,707 EVs from AFP cases, including 763 polioviruses and 944 nonpolio enteroviruses (NPEVs). No WPV was isolated since 1992. The AFP surveillance showed high sensitivity in detecting 143 vaccine-associated paralytic poliomyelitis (VAPP) cases and 6 VDPVs. For environmental surveillance, 217 (61.6%) samples were positive for poliovirus, and altogether, 838 polioviruses and 2,988 NPEVs were isolated. No WPV was isolated in environmental surveillance, although one VDPV2 was identified. Phylogenetic analysis revealed environmental surveillance had the capacity to detect a large scope of NPEVs. The case-based AFP surveillance will be indispensable for detecting VAPP cases and VDPV circulation in countries using oral polio vaccine. Environmental surveillance is advantageous in identifying EV circulation and responding to ongoing circulating VDPV outbreaks and should be expanded to complement the AFP surveillance. IMPORTANCE Interrupting wild poliovirus transmission and stopping circulating vaccine-derived poliovirus (cVDPV) outbreaks have been proposed as two global goals by the World Health Organization in the Global Polio Eradication Initiative (GPEI). This analysis, based on the 28-year acute flaccid paralysis (AFP) surveillance and 8-year environmental surveillance, provides continued high-quality surveillance performance in achieving the GPEI and detecting the circulation of enterovirus. Given the ongoing cVDPV outbreaks in the world, we present the surveillance capacity of environmental surveillance in capturing enterovirus circulation. The final poliovirus (especially VDPV) elimination has become increasingly complex, and the case-based AFP surveillance alone will lead to difficulties in early detecting dynamics of poliovirus transmission and monitoring the extent of environmental circulation. This study goes beyond previous work to provide a detailed comprehensive evaluation of the enterovirus surveillance and can be used to formulate a set of implementation plan and performance indicators for environmental surveillance.
