El año de la primera campaña de vacunación oral contra la poliomielitis según la prensa de Santander (1963)

La poliomielitis emergió como una devastadora epidemia en los países desarrollados durante la primera mitad del siglo XX. Los hallazgos de una vacuna inactivada por Salk (1955) y otra atenuada por Sabin (1957) ofrecieron una solución para eliminarla, coincidiendo con el periodo de mayor incidencia de la enfermedad en España (1950-1963). La respuesta de las autoridades sanitarias españolas no se concretó hasta el año de 1963, cuando el Ministerio de Fomento organizó una campaña nacional de inmunización con vacuna inactivada. Estudios epidemiológicos realizados por investigadores de la Escuela Nacional de Sanidad llevaron al convencimiento de utilizar la vacuna atenuada y a un cambio de estrategia que originó en otoño del mismo año una nueva campaña nacional a cargo del Ministerio de la Gobernación. Este estudio de caso analiza la difusión mediática de ambas campañas en Santander, mediante una revisión de las noticias de prensa publicadas en 2 diarios de ámbito provincial.

Una década de noticias de prensa sobre poliomielitis en la provincia de Guadalajara (1958–1967)

El período de más incidencia de la poliomielitis en España corresponde a los años de 1950 a 1963. La vacuna inactivada antipolio de Salk estuvo disponible a partir de 1955 y varios países la adoptaron para combatir la enfermedad. La actitud de las autoridades sanitarias españolas para abordar el problema fue tibia e ineficaz, sin dar una respuesta decidida para implementar la vacuna de modo sistemático. Hemos realizado un estudio de caso explorando las noticias sobre polio recogidas en dos semanarios de la provincia de Guadalajara durante el decenio de 1958–1967. Los resultados revelan una acumulación de informaciones sesgada y contradictoria, que refleja la incapacidad para tomar decisiones. Desde la negación de la enfermedad y las dudas sobre la vacuna Salk en el primer período, se pasa a la exaltación de la vacuna oral de Sabin, cuando ésta mostró su evidencia tras aplicarla en la campaña de 1963–1964, y que las autoridades se atribuyeron este éxito tardío con una fuerte propaganda mediática.

The late effects of poliomyelitis in Queensland

This paper reports an investigation of new health problems reported by Queensland residents with a prior history of poliomyelitis. 126 people with a past history of paralytic poliomyelitis were recruited from the waiting list for the trial Post Polio Clinic at Queen Elizabeth II Hospital, Brisbane. A self-administered postal questionnaire was used to examine a number of variables including acute poliomyelitis histories; presence, duration and severity of new symptoms consistent with the late effects of poliomyelitis; changes in functional status between the maximal recovery period and the time of the survey and the impact of post-polio symptoms on lifestyle and employment. The most frequent new symptoms reported were muscle weakness (87 per cent), unusual tiredness (79 per cent), joint pain (79 per cent), muscle pain (61 per cent) and muscle cramps (71 per cent). Subjects reported an increased reliance on assistive devices and a decreased level of independence with activities of daily living, particularly with mobility-related tasks. Eight three per cent of subjects had made lifestyle changes as a result of post-polio symptoms and 67 per cent of those subjects in the workforce reported making changes to their employment, such as reduced hours of work.

Polioviruses and other enteroviruses isolated from faecal samples of patients with acute flaccid paralysis in Australia, 1996-2004

Background: Acute flaccid paralysis (AFP) is the most common clinical presentation of acute poliovirus infection, occurring in 0.1-1% of infected cases. AFP surveillance has been used world-wide to monitor the control and eradication of circulating wild poliovirus. This study aims to review the significance of all enteroviruses, including polioviruses, isolated from patients with AFP in Australia between 1996 and 2004. Methods: We undertook a retrospective review of all notified cases of AFP, aged 0-15 years and resident in Australia at the time of notification. We reviewed all available clinical and virological data for these cases and all records of the Polio Expert Committee, which determined the final classification for all cases. Results: There were 335 notified cases that satisfied the case definition for AFP, 162 (48%) of whom had at least one faecal sample tested. Enteroviruses isolated from the faeces of 26 (16%) of the 162 cases were Coxsackie A24, Coxsackie B5, enterovirus 71, enterovirus 75, echovirus 9, echovirus 11 and echovirus 18. In addition, one or more polioviruses were isolated from the faeces of seven patients. Six of seven polioviruses were characterised as Sabin-like, one was not characterised, but all were considered to be incidental isolates. Five of these cases were classified as infant botulism, one case as transverse myelitis and one as a focal mononeuropathy. Conclusion: With the eradication of circulating wild polioviruses, other enteroviruses are being more commonly identified as the cause of polio-like illnesses. In the polio end game, when there is increased testing for polioviruses, it is important to consider infant botulism as a differential diagnosis in cases presenting with AFP.

Viruses and the eye

About 60% of human infections diseases are caused by viruses,including such important diseases as AIDS, polio, rabies and certain forms of cancer. A few groups of viruses are important to optometrists because they either cause a primary eye infection or a systemic viral infection with ocular complications.

Do Psychosocial Interventions Improve Quality of Life and Wellbeing in Adults with Neuromuscular Disorders? A Systematic Review and Narrative Synthesis

Background: Quality of life and well-being are frequently restricted in adults with neuromuscular disorders. As such, identification of appropriate interventions is imperative. Objective: The objective of this paper was to systematically review and critically appraise quantitative studies (RCTs, controlled trials and cohort studies) of psychosocial interventions designed to improve quality of life and well-being in adults with neuromuscular disorders. Method: A systematic review of the published and unpublished literature was conducted. Studies meeting inclusion criteria were appraised using a validated quality assessment tool and results presented in a narrative synthesis. Results: Out of 3,136 studies identified, ten studies met criteria for inclusion within the review. Included studies comprised a range of interventions including: cognitive behavioural therapy, dignity therapy, hypnosis, expressive disclosure, gratitude lists, group psychoeducation and psychologically informed rehabilitation. Five of the interventions were for patients with Amyotrophic Lateral Sclerosis (ALS). The remainder were for patients with post-polio syndrome, muscular dystrophies and mixed disorders, such as Charcot-Marie-Tooth disease, myasthenia gravis and myotonic dystrophy. Across varied interventions and neuromuscular disorders, seven studies reported a short-term beneficial effect of intervention on quality of life and well-being. Whilst such findings are encouraging, widespread issues with the methodological quality of these studies significantly compromised the results. Conclusion: There is no strong evidence that psychosocial interventions improve quality of life and well-being in adults with neuromuscular disorders, due to a paucity of high quality research in this field. Multi-site, randomised controlled trials with active controls, standardised outcome measurement and longer term follow-ups are urgently required.
