Poliomyelitis

Safety, reactogenicity and immunogenicity of GSK Biologicals' hexavalent DTPa-HBV-IPV/Hib vaccine (Infanrix)hexa) was assessed when used for primary vaccination at 3, 4 and 5 months of age (N = 2163), compared to the separate administration of DTPa-IPV/Hib and HBV vaccines (N = 720). A similar safety and reactogenicity profile was demonstrated for both vaccine regimens, as well as a good immune response for all antigen components. By offering protection against six diseases in a series of single injections, the hexavalent DTPa-HBV-IPV/Hib vaccine was shown to be a safe, well tolerated and immunogenic alternative to primary immunization with licensed separately administered vaccines.

Despite launching the polio eradication initiative in 1995, India is among the world's largest reservoir of wild poliovirus with 559 cases of poliomyelitis reported in 2008. This continued failure has been criticised for its negative impact on routine healthcare delivery. We assessed the impact of the pulse polio immunization programme at the primary health level in terms of services, time and cost. All activities during a single round of intensified pulse polio immunization were modelled on actual requirements at the primary health centre at Dayalpur in Haryana. Total person-hours and cost per child vaccinated at the primary health centre were computed. Almost all routine healthcare services at the primary health centre were suspended during the round. Total person-hours consumed were 4446 and the total direct cost was Rs 24.2 per child vaccinated during a single round of the intensified pulse polio immunization programme. A single round of intensified pulse polio immunization ...

Pakistan and Afghanistan remain the only countries where polio is endemic, and Pakistan reports the most cases in the world. Although the rate is lower than in previous years, the situation remains alarming. We conducted a mixed methods study in high-risk areas of Pakistan to identify knowledge, attitudes, and practices of target populations about polio vaccine and its eradication, and to estimate coverage of routine immunization and oral polio vaccine. We surveyed 10,685 households in Karachi, 2522 in Pishin, and 2005 in Bajaur. Some knowledge of polio is universal, but important misconceptions persist. The findings of this study carry strategic importance for program direction and implementation.

Rasoul Pournaki (1921-2008), a prominent researcher, worked with the Pasture Institute of Iran from 1948 to 1978. He served meritoriously to control infectious diseases in Iran. His main research fields were the plague, relapsing fever, and poliomyelitis. He was the Director of Epidemiology and Virology Departments in the Pasteur Institute of Iran. This paper aims to appreciate his scientific contributions in control of infectious diseases by reviewing his notable services and studies.

Poliomyelitis is an infectious disease whose initial symptoms are fever, fatigue, headaches, vomiting, a stiff neck and pains in the limbs. In many cases, the sequelae are irreversible paralysis and may result in death if there is bulbar or respiratory compromise. A set of symptoms, called post-polio syndrome, which appears years after the acute infection, are also described. To analyse the way poliomyelitis has been dealt with in literature, cinema and television. Film and television writers and directors have shown an interest in poliomyelitis and have portrayed it in a correct and realistic manner, both in fiction and in biographies or documentary-type works. Nemesis, Silver wattle, Leave her to heaven or The fall are some examples of literary works on the subject. Cinema has also portrayed polio all the way back to silent movies, with titles such as The woman in his house, The Silver Streak, Sister Kenny or The sessions. This disease and its sequelae have also been portrayed on ...

In polio survivors with calf muscle weakness, dorsiflexion-restricting ankle-foot orthoses (DR-AFOs) aim to improve gait in order to reduce walking-related problems such as instability or increased energy cost. However, evidence on the efficacy of DR-AFOs in polio survivors is lacking. We investigated the effect of DR-AFOs on gait biomechanics, walking energy cost, speed, and perceived waking ability in this patient group. Sixteen polio survivors with calf muscle weakness underwent 3D-gait analyses to assess gait biomechanics when walking with a DR-AFOs and with shoes only. Ambulant registration of gas-exchange during a 6 min walk test determined walking energy cost, and comfortable gait speed was calculated from the walked distance during this test. Perceived walking ability was assessed using purposely-designed questionnaires. Compared with shoes-only, walking with the DR-AFOs significantly increased forward progression of the center of pressure (CoP) in mid-stance and it reduced ...

The Institute for Medical Research, Malaysia, was designated the National Reference Labo- ratory for Poliomyelitis Eradication (NRLPE) in 1992. Since then, our Polio Laboratory has collabo- rated actively with the Disease Control Division, Ministry of Health (MOH), Malaysia and WHO towards achieving polio eradication. Since 1992, the NRLPE has investigated 1,063 stool specimens from 641 acute flaccidparalysis (AFP) cases. One

With more than 2 years having elapsed since the last case of paralytic poliomyelitis occurred in the Western Hemisphere, significant progress has been made towards the global eradication of wild polioviruses. Poliomyelitis is disappearing from Europe, North Africa, Southern Africa, the Middle East, China, and the Pacific. Reported poliomyelitis cases declined to 15,587 cases in 1992. Current eradication strategies recommended by the World Health Organization include national mass campaigns administering oral poliovaccine to all children under 5 years of age, enhanced surveillance to detect cases of acute flaccid paralysis, creating a network of laboratories for viral diagnosis, and targeted immunisation to areas and populations where poliovirus transmission is likely to persist. The major obstacles to eradication include inadequate political support for eradication and insufficient funding, especially for the purchase of vaccine. With additional support for the international eradica...

OBJECTIVE To gain an insight into the phenomenon of social resistance and rumors against pulse polio campaign. DESIGN Qualitative, community-based investigation, mapping perceptions of various stakeholders through in-depth interviews (IDIs), focus group discussions (FGDs), non-formal interactions and observations. SETTING Moradabad and JP Nagar districts of Uttar Pradesh. SUBJECTS IDIs (providers 33, mothers 33, community leaders 10); FGDs (providers 4, mothers 8) and non-formal interactions (156) with community leaders, parents, businessmen, journalists (Hindi and Urdu media), mobilizers, vaccinators and supervisors. RESULTS A distinct machination of social resistance and rumors against oral polio vaccine during supplementary immunization activities (SIA) was observed in some minority dominated areas. The pattern can be understood through a model that emerged through qualitative evidence. Inspite of all this, most parents in minority areas supported the SIAs. Only a few clusters fr...

To strengthen the Nigeria polio eradication program at the operational level, the National Stop Transmission of Polio (N-STOP) program was established in July 2012 as a collaborative effort of the National Primary Health Care Development Agency, the Nigerian Field Epidemiology and Laboratory Training Program, and the US Centers for Disease Control and Prevention. Since its inception, N-STOP has recruited and trained 125 full-time staff, 50 residents in training, and 50 ad hoc officers. N-STOP officers, working at national, state, and district levels, have conducted enumeration outreaches in 46,437 nomadic and hard-to-reach settlements in 253 districts of 19 states, supported supplementary immunization activities in 236 districts, and strengthened routine immunization in 100 districts. Officers have also conducted surveillance assessments, outbreak response, and applied research as needs evolved. The N-STOP program has successfully enhanced Global Polio Eradication Initiative partner...

The relationship between 'narrative' and 'historical-biographical truth' in psychoanalytic treatment has become the subject of many controversial debates in recent years. Findings of contemporary memory research have lead to great scepticism as to whether therapists are able objectively and reliably to reconstruct biographical events on the basis of their observations in the therapeutic situation. Some authors even claim that psychoanalysts should concentrate exclusively on observing the here and now of the patient's behaviour within the transference relationship to the analyst. In this paper it will be discussed whether the baby has been thrown out with the bathwater in this debate. Centred around the insights from a third psychoanalysis with a patient who suffered from a severe case of childhood polio, the hypothesis will be discussed that working through the traumatic experience in the transference with the analyst, as well as the reconstruction of the biographical-historical reality of the trauma suffered, prove to be indispensable for a lasting structural change. Integration of the trauma into one's own personal history and identity is and remains one of the main aims of a psychoanalytic treatment with severely traumatized patients. The reconstruction of the original trauma is indispensable in helping the patient to understand the 'language of the body' and to connect it with visualizations, images and verbalizations. The irreversable wounds and vulnerability of his body as the 'signs of his specific traumatic history' have to be recognized, emotionally accepted and understood in order to live with them and not deny them any longer. Another important aspect in psychoanalysis is to develop the capability to mentalize, in other words, to understand the intentions of central (primary) objects related to the trauma. The concept of 'embodied memory' might be helpful in understanding precisely in what way 'early trauma is remembered by the body'. Observing in detail the sensory-motor coordinations in the analytic relationship enables one to decode the inappropriate intensity of affects and fantasies which match the original traumatic interaction and are revealed as inappropriate reactions in the present, new relationship to the analyst.

The globally synchronized switch from trivalent Oral Polio Vaccine (tOPV) to bivalent Oral Polio Vaccine (bOPV) took place in Nigeria on April 18th 2016. The country is divided into six geopolitical zones. This study reports the experiences and lessons learned from the switch process in the six states that make up Nigeria's south-south geopolitical zone. This was a descriptive retrospective review of Nigeria's switch plan and structures used for implementing the tOPV-bOPV switch in the south-south zone. Nigeria's National Polio Emergency Operation Centre (NPEOC) protocols, global guidelines and reports from switch supervisors during the switch were used to provide background information for this study. Quantitative data were derived from reviewing switch monitoring and validation documents as submitted to the NPEOC RESULTS: The switch process took place in all 3078 Health Facilities (HFs) and 123 Local Government Areas (LGAs) that make up the six states in the zone. A to...

Oral vaccines appear less effective in children in the developing world. Proposed biologic reasons include concurrent enteric infections, malnutrition, breast milk interference, and environmental enteropathy (EE). Rigorous study design and careful data management are essential to begin to understand this complex problem while assuring research subject safety. Herein, we describe the methodology and lessons learned in the PROVIDE study (Dhaka, Bangladesh). A randomized clinical trial platform evaluated the efficacy of delayed-dose oral rotavirus vaccine as well as the benefit of an injectable polio vaccine replacing one dose of oral polio vaccine. This rigorous infrastructure supported the additional examination of hypotheses of vaccine underperformance. Primary and secondary efficacy and immunogenicity measures for rotavirus and polio vaccines were measured, as well as the impact of EE and additional exploratory variables. Methods for the enrollment and 2-year follow-up of a 700 chi...
