A relationship between preceding acute paralytic poliomyelitis and the later development of motor neuron disease has only occasionally been suggested since it was first postulated by Charcot in 1875. The authors recently experienced a 20-year-old male who was considered to have postpoliomyelitis muscular atrophy. We report this case in view of its rarity and necessity of differential diagnosis from other neuromuscular disorders. Clinical presentation included slowly progressive muscle wasting of left thigh for 4 years, mild weakness of left arm and both thigh, intermittent fasciculation, and previous history of acute paralytic poliomyelitis. Electromyographic findings showed fibrillation potentials, positive sharp waves, fasciculations, giant motor unit potentials and reduced interference patterns. Muscle biopsy revealed scattered small angulated fibers, individual myofiber degeneration and mild inflammatory cell infiltration.

OBJECTIVE: To evaluate the psychometric properties of the Fatigue Severity Scale (FSS), the Fatigue Impact Scale (FIS), and the Multidimensional Fatigue Inventory (MFI-20) in persons with late effects of polio (LEoP). More specifically, we explored the data completeness, scaling assumptions, targeting, reliability, and convergent validity. METHODS: A postal survey including FSS, FIS, and MFI-20 was administered to 77 persons with LEoP. Responders received a second survey after 3 weeks to enable test-retest reliability analyses. RESULTS: Sixty-one persons (mean age, 68 years; 54% women) responded to the survey (response rate 79%). Data quality of the rating scales was high (with 0%–0.5% missing item responses), the corrected item-total correlations exceeded 0.4 and the scales showed very little floor or ceiling effects (0%–6.6%). All scales had an acceptable reliability (Cronbach’s α≥0.95) and test-retest reliability (intraclass correlation coefficient, ≥0.80). The standard error of measurement and the smallest detectable difference were 7%–10% and 20%–28% of the possible scoring range. All three scales were highly correlated (Spearman’s correlation coefficient r(s)=0.79–0.80; p < 0.001). CONCLUSION: The FSS, FIS, and MFI-20 exhibit sound psychometric properties in terms of data completeness, scaling assumptions, targeting, reliability, and convergent validity, suggesting that these three rating scales can be used to assess fatigue in persons with LEoP. As FSS has fewer items and therefore is less time consuming it may be the preferred scale. However, the choice of scale depends on the research question and the study design.

OBJECTIVE: To investigate the clinical feature and quantitative electromyographic (QEMG) findings in the patients with post-polio syndrome (PPS). METHOD: Eleven patients who had clinical evidences of antecedent poliomyelitis were evaluated with standardized clinical history, physical examination and QEMG study. If a patient had fulfilled provisional criteria for PPS, he was regarded as PPS and six patients had fulfilled the criteria. Other patients were treated as control group with stable poliomyelitis. Manual muscle testing and needle EMG study including quantitative motor unit analysis was performed at the tibialis anterior and vastus medialis muscles. The existence of abnormal spontaneous activity and parameters of quantitative motor unit analysis, mean duration and amplitude of motor unit action potentials (MUAPs), were compared between PPS and control groups. The correlation between the muscle strength and parameters of QEMG was investigated. RESULTS: Abnormal spontaneous activities were noted in 4 out of 11 patients (36.4%) and three of these 4 patients were PPS. Mean duration and amplitude of MUAPs of tibialis anterior and vastus medialis muscles were not different significantly between the PPS and stable poliomyelitis group (p>0.05). The parameters of MUAPs were poorly correlated with muscle strength. CONCLUSION: Distribution of abnormal spontaneous activities and parameters of QEMG study were not different in PPS and stable poliomyelitis patients. QEMG study may not have additional benefit in differentiating PPS from stable poliomyelitis.

Dermatomyositis (DM) is an idiopathic inflammatory myopathy, characterized by inflammation of the proximal skeletal muscles and typical skin manifestations, which results in symmetric muscle weakness. A 43-year-old man was presented with skin rash and left leg weakness, and he had a history of poliomyelitis. Initially, he was diagnosed as having post-polio syndrome (PPS) due to unilateral muscle weakness and a result of an the electromyography (EMG), which had shown patterns of PPS. After 4 months with conservative therapy for PPS, weakness of bilateral upper arms had developed and skin rashes on his entire body had aggravated and progressed. He was diagnosed as having dermatomyositis, based on elevated muscle enzyme levels, typical skin rashes, and typical EMG findings, which indicated muscle disease. When a patient with previous poliomyelitis has a newly developed muscle weakness or pain, we should consider various possible causes other than PPS.

OBJECTIVE: In patients with a history of acute paralytic poliomyelitis, late progressive muscle weakness, fatigue, pain may arise, a symptom complex of known as post-poliomyelitis syndrome (PPS). Dysphagia may also develop in some PPS patients. The purpose of this study was to assess the presence of is swallowing difficulty in polio survivors and to describe the nature of the swallowing difficulty. METHOD: Polio survivors answered the questionnaire pertaining to swallowing function and received a videofluroscopic evaluation of the oral and pharyngeal phases using 3 consistencies of material: liquid barium; semisolid barium paste; boiled yolk of an egg coated with barium. RESULTS: Of the 16 subjects, 8 had subjective symptoms of swallowing difficulties. All of the 6 PPS patients, regardless of whether they had symptoms of swallowing difficulties, had some abnormal oropharyngeal function through video fluoroscopic swallowing study. CONCLUSION: In patients with post-polio syndrome, there is progressive deterioration of swallowing functions similar to that in the muscles of the limbs. This swallowing dysfunction is not related with their subjective symptoms.

The results of the basic immunization of 3 doses of oral poliomyelitis vaccines for infant and boost immunization of 2 doses of oral poliomyelitis vaccine during 1993-1997 have shown that the poliomyelitis was significant reduced from 152 cases in 1993 to no case in 1998. The last case of poliomyelitis occurred in Phu yen province in 19th January 1997. In 2000, the poliomyelitis was eradicated in Vietnam. However, in order to prevent from returning the disease
Poliomyelitis ; Achievement

Our study is aimed to access polio situation and the surveillance activities of AFP/polio cases in Northern Vietnam from 1992 to 1997. Results showed that due to the quality of the regular and sentinel surveillance improved and the polio vaccination coverage sustained (over 90% for several years), the morbidity of polio has been decreased. There were 146 confirmed cases and 35 wild polio cases in 1992 and up to 1997, there were only 3 confirmed polio cases, none of wild polio cases have been reported since 1994.
Poliomyelitis ; Epidemiology

Data were collected from the Enlarged Immunization Program and the Poliomyelitis Eradication Program (1992-1999), also including inquiry forms and guidelines for detecting, investigating, and processing by Epi-Info. Results shown the epidemic was spread in prevailing of rural population (79.3%), under 5 years old children accounted for 87.9% of cases of poliomyelitis. The outbreaks occurred all around the year with the peak on March, April, May and September, October. Wild virus of the type 1 plays the main role in 97.8% of cases
