Postpolio Syndrome: A Review of Lived Experiences of Patients

Transferencia del flexor hallucis longus en un paciente con síndrome pospoliomielítico con déficit de la función del tendón tibial posterior. Reporte de un caso y técnica quirúrgica

El síndrome pospoliomielítico con déficit de la función del tendón tibial posterior puede presentarse con un pie equino flexible y marcha equina (steppage) en algunos pacientes. Se describe el caso de una paciente que solo conservaba la función muscular del tendón flexor hallucis longus y se decidió su transferencia al mediopié para obtener un pie plantígrado y restaurar la dorsiflexión.

Poliomyelitis is a current challenge: long-term sequelae and circulating vaccine-derived poliovirus

For more than 20 years, the World Health Organization Western Pacific Region (WPR) has been polio-free. However, two current challenges are still polio-related. First, around half of poliomyelitis elderly survivors suffer late poliomyelitis sequelae with a substantial impact on daily activities and quality of life, experiencing varying degrees of residual weakness as they age. The post-polio syndrome as well as accelerated aging may be involved. Second, after the worldwide Sabin oral poliovirus (OPV) vaccination, the recent reappearance of strains of vaccine-derived poliovirus (VDPV) circulating in the environment is worrisome and able to persistent person-to-person transmission. Such VDPV strains exhibit atypical genetic characteristics and reversed neurovirulence that can cause paralysis similarly to wild poliovirus, posing a significant obstacle to the elimination of polio. Immunization is essential for preventing paralysis in those who are exposed to the poliovirus. Stress the necessity of maintaining high vaccination rates because declining immunity increases the likelihood of reemergence. If mankind wants to eradicate polio in the near future, measures to raise immunization rates and living conditions in poorer nations are needed, along with strict observation. New oral polio vaccine candidates offer a promissory tool for this goal.

Gastrointestinal motility disorders in neurologic disease

The extrinsic and autonomic nervous system intricately controls the major functions of the gastrointestinal tract through the enteric nervous system; these include motor, secretory, sensory, storage, and excretory functions. Disorders of the nervous system affecting gastrointestinal tract function manifest primarily as abnormalities in motor (rather than secretory) functions. Common gastrointestinal symptoms in neurologic disorders include sialorrhea, dysphagia, gastroparesis, intestinal pseudo-obstruction, constipation, diarrhea, and fecal incontinence. Diseases of the entire neural axis ranging from the cerebral hemispheres to the peripheral autonomic nerves can result in gastrointestinal motility disorders. The most common neurologic diseases affecting gastrointestinal function are stroke, parkinsonism, multiple sclerosis, and diabetic neuropathy. Diagnosis involves identification of the neurologic disease and its distribution, and documentation of segmental gut dysfunction, typically using noninvasive imaging, transit measurements, or intraluminal measurements of pressure activity and coordination of motility. Apart from treatment of the underlying neurologic disease, management focuses on restoration of normal hydration and nutrition and pharmacologic treatment of the gut neuromuscular disorder.

A twelve-week, four-arm, randomized, double-blind, placebo-controlled, phase 2 prospective clinical trial to evaluate the efficacy and safety of an anthroposophic multimodal treatment on chronic pain in outpatients with postpolio syndrome

INTRODUCTION

Chronic pain and fatigue are the main symptoms of postpoliomyelitis syndrome (PPS). This study aimed to evaluate the efficacy and safety of an anthroposophic multimodal treatment for chronic pain in PPS outpatients.

METHODS

A twelve-week, four-arm, randomized, double-blind, placebo-controlled, phase 2 prospective clinical trial was designed to compare four groups (n = 48): groups A and B received daily active experimental transdermal gel (ETG) or placebo gel (PTG), respectively; groups C and D received weekly external therapies, art therapies, and neurofunctional reorganization, plus either daily ETG or PTG, respectively. The pain symptoms were evaluated through a visual analogue scale (VAS), the McGill questionnaire, and thermography. Quality of life and resilience were evaluated by the WHOQOL-BREF and Antonovsky sense of coherence questionnaires applied at baseline and after the interventions.

RESULTS

No related adverse events occurred, and 10% of the patients reports dysphagia improvement. In the groups C and D, pain reduction was statistically significant in both the placebo group (p = .02, d = 1.315) and in the ETG (p = .005, d = 2.035). However, following the week-to-week evolution of pain with the concomitant use of the ETG, this significant pain reduction occurred earlier from the 4th week and continued to decrease (p = .016, d = 1.369). In the group that received the complete multimodal treatment, the greatest significant benefit in increasing quality of life occurred in the physical domain and elevation in resilience with an emphasis on meaning and comprehension domains.

CONCLUSIONS

The anthroposophic multimodal treatment group presented both safety and efficacy as an analgesic in the groups that received the nonpharmacological therapies, much earlier when associated with the ETG. The multimodal approach corresponded to the pattern of better efficacy for both pain reduction and improvement in quality of life and resilience.
