A pneumonia por Pneumocystis carinii (PPC), que é a infecção oportunista que mais comumente põe em risco a vida de pacientes com síndrome da imunodeficiência adquirida (SIDA), tem sido há bastante tempo associada a outros estados de imunodeficiência. Os relatos iniciais sugeriram que a apresentação clínica da PPC em SIDA difere de sua apresentação em outras situações, embora ambas tenham sofrido modificações nos últimos anos. O objetivo do presente estudo é comparar os achados clínicos e laboratoriais da PPC em SIDA com os de pacientes portadores de PPC sem SIDA. Foram revisados os prontuários médicos de todos os pacientes em nossa instituição que tiveram o diagnóstico confirmado de PPC e SIDA durante o ano de 1994 (17 pacientes) e sem SIDA no período de 1992-1994 (dez pacientes). Quando da apresentação, os pacientes sem SIDA tinham uma duração de sintomas significativamente menor (8,4 ± 7,7 vs 19,5 ± 10,2 dias, p < 0,05), menor PaO2 média a ar ambiente (47 ± 8,2 vs 63 ± 10mmHg, p < 0,05), e mais freqüente infiltrado unilateral no radiograma do tórax (60 vs 6%, p < 0,05). O índice de mortalidade da PPC foi marcadamente maior nos pacientes sem SIDA (40 vs 6%, p < 0,05), e este fato estava associado com retarde no início do tratamento específico nestes pacientes. Devido a seu curso mais agudo, apresentação radiológica atípica e alto índice de mortalidade, concluímos que o diagnóstico de PPC deve ser afastado em pacientes que recebem terapia imunossupressora e que profilaxia anti-PPC deve ser fortemente considerada em pacientes que serão imunossuprimidos.

Objective: To describe the factors associated with nonadherence to TB chemoprophylaxis in patients older than 15 years of age treated via referral TB control programs. Methods: A historical cohort study was carried out based on medical charts related to cases treated via referral TB control programs in the city of Vitória, Brazil, between 2002 and 2007. Cases of infection with Mycobacterium tuberculosis were stratified into two groups: health care workers (HCW group); and individuals who were not health care workers (NHCW group). Results: A total of 395 patients were included in the study: 35 in the HCW group and 360 in the NHCW group. The mean age in the HCW and NHCW groups was 34.8 and 32.4 years, respectively (p = 0.36). Of the 35 patients in the HCW group, 29 (82.9%) were female, compared with 180 (50.0%) of the 360 patients in the NHCW group. In the HCW and NHCW groups, respectively, 15 (42.9%) and 169 (46.9%) of the patients were contacts of TB cases. In addition, 9 (25.7%) and 157 (78.5%) the HCW and NHCW group patients, respectively, were HIV-infected. Nonadherence to chemoprophylaxis was 37.1% and 21.9% in the HCW and NHCW groups, respectively (p = 0.045). In the multivariate analysis, the factors associated with nonadherence were being a health care worker (OR = 8.60; 95% CI: 2.09-35.41), being HIV-infected (OR = 4.57; 95% CI: 1.2-17.5) and having had contact with a TB patient (OR = 2.65; 95% CI: 1.15-6.12). Conclusions: In order to improve adherence to TB chemoprophylaxis, new TB control program strategies are needed, especially for health care workers and HIV-infected patients.

Objective: To evaluate the use of family members as supervisors of directly observed therapy (DOT) in patients with tuberculosis.Methods: This was a prospective descriptive study involving patients diagnosed with pulmonary tuberculosis. The sample comprised 98 patients. A standardized protocol was implemented in order to train the patient and their families. After the training, the patient was allowed to choose either a family member or a health care worker as a supervisor. Absolute and relative frequencies were used in descriptive data analysis. Results: A family member supervisor was chosen by 94 patients (96%). The cure rate was 99%. The partner was chosen by 49% of the patients, and other family members were chosen by 28%. The heath care team needed to take over DOT in 3% of the cases. Regular attendance at follow-up appointments was 67%. It was observed that 24% of the problems in this DOT model referred to the family supervisor forgetting to administer the medication or to the patient forgetting to take it; 39% of the patients forgot to take the medication for one day, and 31% forgot to take it for two days. There was change of supervisor in 9% of the sample, medication was lost by the patient sometime during treatment in 9%, and patient drug intolerance occurred in 8%. Conclusions: DOT supervised by a family member has proven an effective and low-cost technique. However, compliance is not due to one single factor but to the combination of strategies adopted: bus passes; educational measures and especially the individualized approach.

Objetivo: Realizar a tradução para a língua portuguesa e a adaptação cultural para uso no Brasil do Quality of Communication Questionnaire (QOC) para pacientes com DPOC em cuidados paliativos. Métodos: Após a aprovação do autor do questionário e do comitê de ética da instituição, a versão original do QOC com 13 itens foi traduzida, de forma independente, por dois tradutores brasileiros com fluência na língua inglesa. Uma síntese das duas traduções foi realizada por uma médica bilíngue e os dois tradutores, que chegaram a um consenso, gerando uma versão na língua portuguesa. Essa versão foi retraduzida por dois tradutores nativos de países de língua inglesa com fluência na língua portuguesa. Para resolver quaisquer discrepâncias, um comitê de especialistas comparou a versão original com todas as versões produzidas e, assim, obteve-se a versão pré-final do QOC. O pré-teste foi aplicado em 32 pacientes internados em UTIs de três hospitais públicos da grande Florianópolis (SC) para avaliar a clareza e a aceitabilidade cultural da versão pré-final do QOC. Resultados: A média de idade dos pacientes foi de 48,5 ± 18,8 anos. A maioria dos itens foi bem compreendida e aceita, recebendo pontuações ≥ 8. Um item, sobre morte, suscitou dificuldades na compreensão dos participantes do pré-teste. Ao submeter a retradução ao autor do QOC, ele solicitou alterações em dois itens, que foram acatadas. Após essas alterações, a versão final foi aprovada. Conclusões: A tradução e a adaptação cultural do QOC para uso no Brasil foi concluída com sucesso.

Objective: To describe the epidemiological profile of tuberculosis cases reported among health care workers in the Tuberculosis Control Program of the Cassiano Antonio of Moraes University Hospital in Vitoria, Brazil. Methods: A retrospective descriptive study of secondary data was conducted between 2002 and 2006. Results: Twenty-five cases of health care workers with tuberculosis were reported: 8 in nursing technicians (32%); 4 in doctors (16%); 3 in nurses (12%); 2 in radiology technicians (8%) and 8 in professionals from other categories (32%). Of those 25 health care workers, 14 (56%) were male and 11 (44%) were female. The incidence of the disease was highest among those from 35 to 39 years of age. The predominant clinical presentation was extrapulmonary (12 cases, 48%), followed by pulmonary (11 cases, 44%) and a combination of the two (2 cases, 8%). Regarding comorbidities, AIDS, alcoholism and smoking, respectively, were present in 33.3% of the study population. Outcomes were as follows: 22 cases of cure (88%); 2 transfers (8%); and 1 death (4%). The proportion of health care workers diagnosed with tuberculosis in the period studied was 2.53%. Conclusions: The results show the need for heath care workers who work in the tuberculosis control program to fill out the field "professional occupation" on the tuberculosis case registry database reporting forms. In addition, this situation draws attention to the need to implement an occupational tuberculosis control program.

Objective: To compare clinical, radiological and laboratory aspects of household contacts, aged 15 or younger, of patients presenting a positive culture for Mycobacterium tuberculosis. Methods: This was a cohort study comparing children and adolescents (≤ 15 years of age) who were household contacts of TB cases presenting positive sputum smear and positive culture results (exposed group, n = 100) or negative sputum smear and positive culture results (unexposed group, n = 55). All of the contacts were evaluated via the TB control program of a university hospital in the city of Vitória, Brazil, between July of 2003 and December of 2006. Results: Of the 155 minors evaluated, 87 (56.1%) were female and 68 (43.9%) were male. Of those 155, 28 (18%) were aged 5 or younger, 62 (40%) were aged 5-9, and 65 (42%) were aged 10-15. Symptoms of the disease were found in 17 (17%) of the 100 contacts in the exposed group and in 9 (16%) of the 55 in the unexposed group (p = 0.86). Chest X-rays showed alterations in 20 (21%) and 2 (4%) of the contacts in the exposed and unexposed groups, respectively (RR = 6.9; p = 0.004). In the exposed and unexposed groups, respectively, 35 (38%) and 10 (18%) of the contacts presented positive results on the tuberculin skin test (RR = 2.8; p = 0.01). Of the 100 contacts in the exposed group, 5 (5%) were diagnosed with TB, which was not diagnosed in any of those in the unexposed group (p = 0.08). Conclusions: Although no significant difference was found between the two groups regarding the incidence of TB, it is of note that there is a greater risk of becoming infected with M. tuberculosis if the bacterial load of the index case is high.
