Immunity of children in Kharkov against poliomyelitis

The study of the state of herd immunity among the children of Kharkov, carried out in 1980-1981, has revealed different immunity levels in children of different age. The conclusion has been made that the constant control of the state of immunity to 3 types of poliovirus is necessary, especially in infants and in school children, as well as in those not attending children's institutions.     

The role of candidal histolytic enzymes on denture-induced stomatitis in patients living in retirement homes

Material and methods: Fifty nine elders wearing complete dentures and living in retirement homes in Curitiba (southern Brazil), were divided into two groups: group #1, 26 patients with denture‐induced stomatitis and group #2, 33 patients without denture‐induced stomatitis. The two groups were evaluated in relation to the degree of denture‐induced stomatitis, salivary fungal loads, and secretion of some histolytic enzymes. Results: Patients from group #1 showed higher degrees of colonisation by Candida albicans (p = 0.031). Candida krusei, Candida tropicalis, and Candida parapsilosis were also isolated, but there were no differences between the groups (p > 0.05). Secretory aspartyl protease (Sap) and chondroitinase did not show significant differences among the isolated Candida spp. in the two groups. Phospholipase secretion rates were higher among the strains of C. albicans from group #2 (p = 0.036). The same behaviour was not detected for non‐albicans Candida species. Conclusions: The results could infer that differences in the secretion rates of candidal histolytic enzymes should not be imputed as imperative for the progress of denture‐induced stomatitis.     

Oral health of the elderly living in residential homes in Slovenia

doi: 10.1111/j.1741‐2358.2011.00497.x
Oral health of the elderly living in residential homes in Slovenia Objectives:  To evaluate oral health status of the elderly, living in eight randomly selected residential homes for senior citizens across the country. Background: The percentage of the elderly is growing worldwide. With ageing, risks of various oral diseases, including dental caries and periodontal disease, are growing. Methods: Altogether 296 elderly people (88 men, 208 women) of average age 79.89 ± 7.4 years were questioned about their medical condition and oral health practice and examined orally. Evaluation of clinical examination was carried out by DMFT, plaque index ( 10 ) and Community Periodontal Index of Treatment Need (CPITN). Results: Of 296 participants, 106 (35.8%) were edentulous, 95 (32.1%) had one to nine teeth and 95 persons (32.1%) had 10 or more teeth. The average number of teeth in an individual was small: 6.76 ± 7.47. The average number of teeth with caries lesions was 3.59 ± 4.70, filled teeth 1.94 ± 3.63 and teeth without caries or fillings 1.19 ± 2.41. The average DMFT value was 30.75. In 69.5% of participants, dental plaque was visible with the naked eye. Of 171 subjects, in whom CPITN index was appraised, 81.9% would need oral hygiene education, 56.7% would need scaling and root planning and 21.6% would need periodontal surgical treatment. Conclusions: The results of this study indicate poor oral health of the elderly living in residential homes situated in different towns in Slovenia. It is of utmost importance to highlight the necessity of improving oral health care of this population.     

The incidence of haemagglutination inhibiting antibodies for influenza A and B virus strains in sera of children and infants

Summary The incidence of antibodies for influenza A (PR8) and influenza B virus (Lee and B (1950 Ned)) in the sera of 138 children from 0 to 5 years was very low. 60 Per cent of the investigated sera contained antibodies for influenza A-prime virus (FM1).     

Incidence of malaria among children living near dams in northern Ethiopia: community based incidence survey

ObjectiveTo assess the impact of construction of microdams on the incidence of malaria in nearby communities in terms of possibly increasing peak incidence and prolonging transmission.DesignFour quarterly cycles of malaria incidence surveys, each taking 30 days, undertaken in eight at risk communities close to dams paired with eight control villages at similar altitudes but beyond flight range of mosquitoes.SettingTigray region in northern Ethiopia at altitudes of 1800 to 2225 m.SubjectsAbout 7000 children under 10 years living in villages within 3 km of microdams and in control villages 8-10 km distant.ResultsOverall incidence of malaria for the villages close to dams was 14.0 episodes/1000 child months at risk compared with 1.9 in the control villages—a sevenfold ratio. Incidence was significantly higher in both communities at altitudes below 1900 m.ConclusionsThere is a need for attention to be given to health issues in the implementation of ecological and environmental development programmes, specifically for appropriate malaria control measures to counteract the increased risks near these dams.

Key messages

• Environmental development may have important effects on the epidemiology of vector borne diseases such as malaria
• This may be particularly important where disease transmission is unstable—for example, in highland areas
• Children in villages near recently constructed microdams in northern Ethiopia had a significantly increased risk of malaria
• It seems that this irrigation development programme is leading to increased malaria transmission across a range of altitudes and seasons
• Intersectoral collaboration is necessary in development projects that may affect communities both positively and negatively

     

The incidence of fungal spores in the ambient air and inside homes: Evidence from London

Little research has been carried out in London concerning fungal spore prevalence yet this information may help to elucidate geographical patterns of asthma and hay fever. Although many types of spore reach peak concentrations outdoors in late-summer, the incidences in the indoor environment may be more important through the winter because of heating and poor ventilation. Daily average concentrations of fungal spores in the ambient atmosphere were monitored with a Burkard volumetric spore trap on an exposed roof in North London from autumn 1991 until the summer of 1992. Indoor spore measurements were taken in 19 homes in the vicinity through the winter months, both by direct air sampling using a portable Burkard sampler and by dust culture. Trends in the occurrence and concentrations of fungal spores indoors and outdoors were examined. Relationships between the abundance of selected allergenic fungi and features of the houses were analysed including age of dwelling, dampness, cleanliness and presence of pets.Aspergillus andPenicillium were the most frequently occurring spore types in the homes. Overall, high spore incidence was associated with dampness and dust accumulation. The outdoor spore samples revealed generally low concentrations through the winter until March when concentrations of many types includingCladosporium, Epicoccum andAlternaria increased in abundance in response to the warmer weather. Even during the late-spring and early-summer, concentrations of most fungal spores were notably below those reported for rural sites.     

Non-verbal communication of the residents living in homes for the older people in Slovenia

Aging of the population is a growing problem in all developed societies. The older people need more health and social services, and their life quality in there is getting more and more important. The study aimed at determining the characteristics of non-verbal communication of the older people living in old people's homes (OPH). The sample consisted of 267 residents of the OPH, aged 65-96 years, and 267 caregivers from randomly selected twenty-seven OPH. Three types of non-verbal communication were observed and analysed using univariate and multivariate statistical methods. In face expressions and head movements about 75% older people looked at the eyes of their caregivers, and about 60% were looking around, while laughing or pressing the lips together was rarely noticed. The differences between genders were not statistically significant while statistically significant differences among different age groups was observed in dropping the eyes (p = 0.004) and smiling (0.008). In hand gestures and trunk movements, majority of older people most often moved forwards and clenched fingers, while most rarely they stroked and caressed their caregivers. The differences between genders were statistically significant in leaning on the table (p = 0.001), and changing the position on the chair (0.013). Statistically significant differences among age groups were registered in leaning forwards (p = 0.006) and pointing to the others (p = 0.036). In different modes of speaking and paralinguistic signs almost 75% older people spoke normally, about 70% kept silent, while they rarely quarrelled. The differences between genders were not statistically significant while statistically significant differences among age groups was observed in persuasive speaking (p = 0.007). The present study showed that older people in OPH in Slovenia communicated significantly less frequently with hand gestures and trunk movements than with face expressions and head movements or different modes of speaking and paralinguistic signs. The caregivers should be aware of this and pay a lot of attention to these two groups of non-verbal expressions. Their importance should be constantly emphasized during the educational process of all kinds of health-care professionals as well.
