Macaque monkeys are susceptible to measles infection which triggers temporary immuno-depression similar to the well known phenomenon in humans. It is known that feral monkeys become infected with measles virus when they are exposed to humans. Since Macaca mulatta and M. fascicularis are species used to assay the neurovirulence of oral poliovirus vaccine, the immunodepression caused by measles infection of the test monkeys could significantly alter the results of the neurovirulence test. The serum titers of measles-neutralizing antibodies were studied in over 1500 monkeys used for neurovirulence tests. A high proportion of the feral monkeys had measles antibodies (51-100%); in contrast, none of 493 M. fascicularis monkeys which had been bred in a primate colony under strict isolation measures was found positive for measles antibodies. An increase in the prevalence of measles in the population of Ontario and Quebec provinces was accompanied with an increase in the proportion of measles-positive monkey and their serum antibody titers were found higher. It was observed that monkeys used in tests that had been performed during high measles prevalence presented with a poliomyelitis of more pronounced severity clinically and histologically. The analysis of 29 tests conducted on type 1 vaccines over several years showed a positive correlation (correlation coefficient = 0.5141, P less than 0.0022) between severity of poliomyelitis and the presence of measles serum antibodies in test monkeys (some animals seroconverted during the test). A similar observation, when type 3 Sabin vaccines were tested in M. fascicularis, was recently reported from another laboratory in Ontario.

In 1980 WHO defined disability as a functional limitation due to impairment, and handicap as the psychosocial disadvantage consequent to disability. This study was designed to investigate the advent of handicap in a group of adults physically disabled by poliomyelitis in childhood by comparing them to their age- and sex-matched siblings. An area survey was conducted in West Beirut and its Southern Suburb and 240 such disabled people and their siblings were identified and interviewed. Handicap was defined as disadvantage in six areas, namely, education, work, income, marital status, housing, and mental well-being. The differences between each disabled person and his/her sex-matched sibling were assessed. Significant differences were noted in employment (Odds ratio (OR) = 4.20, confidence interval (CI): 1.38-15.26), social class (OR = 2.67, CI: 1.11-6.79), income (OR = 2.88, CI: 5.57-113.3) and marital status for both the disabled people compared with their elder siblings (OR = 20.00, CI: 5.57-113.30) and for those disabled compared with their younger siblings (OR = 4.60, CI: 1.53-16.55). Multivariate analyses of the explanatory factors for each of these six areas of disadvantage among the disabled group showed that educational discrepancies cut across social class differences (OR = 1.90, CI: 1.00-3.61), income differences (OR = 1.44, CI: 0.97-2.14), and symptoms of depression (OR = 2.33, CI: 1.42-3.84). Marital-status disadvantage was related to lower income groups and disabled women (OR = 1.66, CI: 1.10-2.49; OR = 1.60, CI: 1.07-2.39).(ABSTRACT TRUNCATED AT 250 WORDS)

Even as the physical causes and treatments for post-polio sequelae (PPS) are being identified, psychological symptoms--chronic stress, anxiety, depression, and compulsive, Type A behavior--are becoming evident in polio survivors. Importantly, these symptoms are not only causing marked distress but are preventing patients from making the lifestyle changes necessary to treat their PPS. Neither clinicians nor polio survivors have paid sufficient attention to the acute polio experience, its conditioning of life-long patterns of behavior, its relationship to the development of PPS, and its effect on the ability of individuals to cope with and treat their new symptoms. We describe the acute polio and post-polio experiences on the basis of patient histories, relate the experience of polio to the development of compulsive, Type A behavior, link these behaviors to the physical and psychological symptoms reported in the National Post-Polio Surveys, and present a multimodal behavioral approach to treatment.

The results of medical examinations carried out on 212 missionary personnel from one missionary society returning on leave to the UK are presented. The great majority of missionaries worked in developing countries. They served in 27 countries altogether and for a total of 488 person years. The commonest illnesses reported overseas were malaria (87.3 per 1000 person years at risk), diarrhoea (63.5), anxiety (63.5), depression (41.0) and giardiasis (38.9). More illnesses were reported from West Africa (698 per 1000 person years at risk) than from any other region. Ten people (4.7%) were repatriated for health reasons and 10 relatives also returned as a consequence. Sixty per cent of those returning did so because of psychiatric illness. The highest rates of immunization achieved were for yellow fever (100% of those travelling to affected countries), tetanus (93%), polio (85%), typhoid (71%) and tuberculosis (53%). The results of urinalysis (100% of adults), full blood counts (78% of adults) and stool tests (74% of all people) are reported. The study shows that the history and psychiatric examination are an important part of the medical examination of people returning from overseas. Physical examination and urinalysis did not contribute much information, although the full blood count and absolute eosinophil count were useful tests.

Many of the hundreds of thousands of survivors of polio are now developing postpolio syndrome. Symptoms include progressive muscle weakness, fatigue, decreased endurance, joint and muscle pain, weight gain, respiratory difficulties, and sleep disturbance, often precipitated or exacerbated by a Type-A Personality pattern. A postpolio patient with Type-A Personality was taught self-hypnosis as a vital component of treatment. Pre-post testing included the Profile of Mood States, the State-Trait Anxiety Inventory, the State-Trait Anger Inventory, and the Personal Orientation Inventory; the patient's spouse was interviewed during the follow-up. At the 6-month follow-up, improvements were documented in pain level, depression, self-regard, self-acceptance, capacity for intimate contact, time competence (living in the present), confusion, anxiety, insomnia, and in trait and state anger. Only a mild improvement occurred in fatigue, and no improvement was found in weight control. Follow-up at 12 months confirmed the maintenance of improvements. Self-hypnosis training may prove extremely helpful for postpolio patients and may prove helpful in modifying central characteristics of Type-A Personality.

A survey was conducted to better understand complaints of fatigue in patients previously diagnosed as having polio. Eighty-six individuals with postpolio syndrome and 20 healthy controls completed a questionnaire about their fatigue, the Beck Depression Inventory, and the CAGE questionnaire. The results showed that fatigue in postpolio syndrome usually occurred on a daily basis and increased in severity as the day progressed. Both the study group and controls described their fatigue as tiredness and a lack of energy. However, physical weakness was reported only in the postpolio group. Minimal physical exercise exacerbated fatigue in 48% of the postpolio group, whereas it diminished fatigue in 70% of the controls and in 15% of the postpolio group. Twenty-seven percent of the postpolio group and none of the controls reported mild to moderate depressive symptoms. However, depression, age, alcohol abuse, and employment status did not significantly affect the differences between groups in reported prevalence or description of chronic fatigue. Criteria to separate psychologic from organic causes of fatigue and treatment interventions are discussed.

Ninety-three men and women with histories of polio were administered the Symptom Check List-90 Revised (SCL-90R), Psychosocial Adjustment to Illness Scale-Self Report (PAIS-SR), and a questionnaire about their polio histories. The SCL-90R and PAIS-SR are measures of emotional and psychosocial functioning. Two samples were used: a clinic sample (n = 71) and a postpolio support group sample (n = 22). Initial results for both on the SCL-90R and PAIS-SR indicated elevated scores on a number of subscales. SCL-90R subscale elevated scores for men included those for somatization, depression, anxiety, hostility, and phobia, whereas for women there were elevations on measures of somatization, depression, anxiety, and psychoticism. Elevations were found in the following subscales on the PAIS-SR (pooling men and women): health care orientation, social environment, and extended family relationships. Men scored slightly, but not significantly, higher than women in the SCL-90R except for the hostility subscale, in which the difference was significant (p less than 0.05). Symptom profiles indicated psychologic distress. Comparisons with variables associated with polio and its late effects (such as severity of initial polio, use of an iron lung during initial illness, number of involved limbs, etc) were not statistically significant.

The indications, contraindications, technique, and end results of thirty-four tarsometatarsal truncated-wedge arthrodeses performed for cavus and equinovarus deformity of the fore part of the foot were reviewed. The etiology of deformity included idiopathic pes cavus, equinus deformity of the fore part of the foot, residual club foot, poliomyelitis, and compartment syndromes. With th truncated-wedge arthrodesis the subtalar joint is not violated and selective correction of any combination of depression of the metatarsal head is readily accomplished. By strict adherence to the indications and exacting surgical technique, complications are rare and the end results are uniformly excellent.

The innervation of muscles in patients with the post-polio syndrome (PPS) may differ from limb to limb or even within the same limb because of the segmental nature of the initial involvement and the varying degree of subsequent recovery. Consequently, the compensatory effort of the neighboring muscles varies even in the same limb. Clinicohistological studies have confirmed that in PPS the various muscle groups differ according to whether they were affected during the acute polio and have recovered (partially or completely), or whether they were clinically spared during the original disease, in spite of subclinical involvement. Because the impact of the late effects of polio is also variable in these muscle groups, the effect of therapies may be different not only from patient to patient and from limb to limb, but also from muscle to muscle within the same limb. These variables require careful statistical determination of the sample size at the design of a trial. Another problematic issue in the therapy of PPS is to define the end point of therapy. The two disabling PPS symptoms, excessive fatigue and new muscle weakness, can coexist. An experimental therapeutic design must focus separately on the fatigue, using validated fatigue scales, and on muscle weakness, using quantitative muscle testing. Another methodological concern is the placebo-controlled design. Patients with PPS, even those without depression, can be prone to a placebo effect; hence the need for controlled trials. Finally, the length of a trial remains unresolved because of the slow and unpredictable progression of PPS that varies from patient to patient. Until the natural history of PPS is defined, therapies aimed at arresting disease progression are not reliable.

Post-polio syndrome (PPS) refers to the late development of new neuromuscular symptoms in previously stable poliomyelitis patients. Whether psychological disturbance plays a role in the manifestation of symptoms in these patients is unclear. We examined 22 patients fulfilling the clinical criteria for PPS with the Minnesota Multiphasic Personality Inventory-II (MMPI-II), Beck Depression Inventory, Spielberger State-Trait Anxiety Scales, Chapman and Chapman Psychosis-Proneness Scales, Fatigue Scales, a neurobehavioral rating scale, and Cognitive Symptoms Self-Report Scales. The overwhelming majority of scale scores were within normal limits, and there was no indication that psychopathologic symptoms were associated with the development or severity of new muscle weakness in PPS patients. Women with PPS had significantly more somatic complaints, but were less socially isolated than men with PPS. This study confirms that the development or severity of new muscle weakness in carefully diagnosed PPS patients is not due to, or influenced by, underlying psychopathology.
