Limited activity and social participation after hospital discharge from leprosy treatment in a hyperendemic area in north Brazil

INTRODUCTION: Neural damages are among the main factors that contribute to physical disability in leprosy. Systematic monitoring using a broad physical, psychological and social approach is necessary. OBJECTIVE: The objective of this study was to characterize the limitation of activity and social participation and its correlation with disabilities and/or impairment in individuals after being discharged from a multidrug leprosy therapy. METHOD: A cross-sectional study conducted in Araguaína, state of Tocantins, which is a leprosy hyperendemic municipality. We included cases of patients who were discharged from treatment considered as cured from January 2004 to December 2009. We performed dermatological examination and applied the Screening Activity Limitation and Safety Awareness (SALSA) and social participation scales. RESULTS: We included 282 individuals (mean age: 45.8 years old). The paucibacillary operational classification was more common (170; 60.3%). The eye-hand-foot score ranged from 0 to 12 (mean: 0.7). A total of 84 (29.8%) individuals presented limited activity. A slight restriction in social participation occurred in 18 (6.3%) cases. There was a statistically significant correlation between activity limitation, age (r = 0.40; p < 0.0001) and degree of functional limitation (r = 0.54; p < 0.0001), as well as of restricted social participation, activity limitation (r = 0.56, p < 0.0001) and functional limitations (r = 0.54, p < 0.0001). CONCLUSION: Functional limitation due to leprosy had an impact on the conduct of activities and social participation after the discharge from a leprosy treatment. The association between Screening of Activity Limitation and Safety Awareness and participation scales will assist in designing evidence-based assistance measures

Desnutrição neonatal e microbiota normal da cavidade oral em ratos Neonatal malnutrition and normal microbiota of the oral cavity in rats

OBJETIVO: Avaliar a influência da desnutrição neonatal sobre o padrão e o crescimento de bactérias aeróbias, da microbiota normal da cavidade oral, em ratos Wistar adultos. MÉTODOS: O material da cavidade oral foi coletado através de swabs embebidos em 40µL de solução salina estéril e colocados em tubos estéreis contendo 960µL de brain heart infusion. Posteriormente, fez-se homogeneização de cada uma amostra. Então, destes 1.000µL, retirou-se 1µL e este foi semeado em placas de Petri contendo Agar-sangue e Levine para isolamento e identificação de bactérias Gram+ e Gram-, respectivamente. Essas placas foram incubadas em estufa bacteriológica a 37ºC, 48 horas, e as unidades formadoras de colônias que cresceram foram contadas e seus percentuais calculados. Para a bacterioscopia foram confeccionadas lâminas coradas pelo método de Gram. RESULTADOS: Do 5º ao 21º dia de vida os pesos corporais do grupo desnutrido (33,6g:42,8g, desvio-padrão=27,2g) foram menores (p<0,001) que os do grupo nutrido (52,5g:56,3g, desvio-padrão=24,0g). Dos 60 aos 120 dias de vida os pesos foram reduzidos no grupo desnutrido (248,2g:290,2g, desvio-padrão=220,2g), quando comparados aos do grupo nutrido (306,2g:319,4g, desvio-padrão=219,5g) teste Mann Whitney, p<0,05. A microbiota foi composta de menor número de bactérias no grupo nutrido (4,2x10(6) unidades formadoras de colônias, desvio-padrão=1,2x10(6) unidades formadoras de colônias de bactérias/mL), comparado ao grupo desnutrido (7,4x10(6) unidades formadoras de colônias, desvio-padrão=1,0x10(6) unidades formadoras de colônias de bactérias/mL) teste "t", (p=0,026). Das bactérias isoladas em culturas, observou-se um padrão bacteriano semelhante nos dois grupos, com 70% de bactérias gram-positivas e 30% de bactérias gram-negativas. CONCLUSÃO: A desnutrição neonatal foi efetiva em reduzir o peso corporal e aumentar o crescimento bacteriano. Embora o padrão bacteriano não tenha sido alterado, o aumento do crescimento bacteriano pode induzir a um desequilíbrio na microbiota oral desfavorecendo assim, o hospedeiro.<br>OBJECTIVE: To evaluate the influence of neonatal malnutrition on the pattern and growth of aerobic bacteria of the normal bacterial flora of the oral cavity in adults Wistar rats. METHODS: In the present study, the material of the oral cavity was collected through swabs soaked in 40µL of sterile saline solution. After the collection, each swab was placed in a sterile tube containing 960µL of brain heart infusion. Later, the samples were homogenized. Then, from the 1.000µL, 1µL was collected with a gauged loop to be sowed in Petri dishes containing Agar-blood and Agar-Levine, for the isolation and identification of the Gram-positive and Gram-negative bacteria respectively. The plates were placed into a bacteriological incubator, 37ºC, for 48 hours and the colony-forming units that grew were counted and their percentages were calculated. For bacterioscopy, slides were stained with the Gram method. RESULTS: From the 5th to the 21st day of life, body weight of the undernourished group (33.6g:42.8g, standard deviation=27.2g) was smaller (p<0.001) than that of the nourished group (52.5g:56.3g, standard deviation=24.0g). From the 60th to the 120th days of life the body weight of the undernourished group (7.4.x.10(6) colony-forming units, standard deviation=1,0x10(6) colony-forming units bacteria/mL) decreased when compared to that of the nourished group (306.2g:319.4g, standard deviation=219.5g), Mann-Whitney test, p<0,05. The microbiota was composed of a smaller number of bacteria in the nourished group (4.2 x10(6) colony-forming units, standard deviation=1.2x10(6) colony-forming units bacteria/mL) when compared with the undernourished group (7.4x10(6) colony-forming units, standard deviation=1.0x10(6) colony-forming units bacteria/mL), Student's "t" test (p=0.026). From the bacteria isolated in cultures, a similar bacterial pattern was observed in both groups, with 70% of Gram-positive bacteria and 30% of Gram-negative bacteria. CONCLUSION: Neonatal malnutrition was effective in decreasing body weight and increasing bacterial growth. Although the bacterial pattern was not altered, the increase in bacterial growth may induce an imbalance of the oral microbiota, being a threat to the host
