Professional and community satisfaction with the Brazilian family health strategy

OBJECTIVE: To analyze the strengths and limitations of the Family Health Strategy from the perspective of health care professionals and the community. METHODS: Between June-August 2009, in the city of Vespasiano, Minas Gerais State, Southeastern Brazil, a questionnaire was used to evaluate the Family Health Strategy (ESF) with 77 healthcare professionals and 293 caregivers of children under five. Health care professional training, community access to health care, communication with patients and delivery of health education and pediatric care were the main points of interest in the evaluation. Logistic regression analysis was used to obtain odds ratios and 95% confidence intervals as well as to assess the statistical significance of the variables studied. RESULTS: The majority of health care professionals reported their program training was insufficient in quantity, content and method of delivery. Caregivers and professionals identified similar weaknesses (services not accessible to the community, lack of healthcare professionals, poor training for professionals) and strengths (community health worker-patient communications, provision of educational information, and pediatric care). Recommendations for improvement included: more doctors and specialists, more and better training, and scheduling improvements. Caregiver satisfaction with the ESF was found to be related to perceived benefits such as community health agent household visits (OR 5.8, 95%CI 2.8;12.1), good professional-patient relationships (OR 4.8, 95%CI 2.5;9.3), and family-focused health (OR 4.1, 95%CI 1.6;10.2); and perceived problems such as lack of personnel (OR 0.3, 95%CI 0.2;0.6), difficulty with access (OR 0.2, 95%CI 0.1;0.4), and poor quality of care (OR 0.3, 95%CI 0.1;0.6). Overall, 62% of caregivers reported being generally satisfied with the ESF services. CONCLUSIONS: Identifying the limitations and strengths of the Family Health Strategy from the healthcare professional and caregiver perspective may serve to advance primary community healthcare in Brazil.

Introducao e expansao da Leishmaniose visceral americana em humanos no estado de Sao Paulo, 1999-2011

OBJETIVO : Analisar a expansão da ocorrência de leishmaniose visceral americana em humanos e identificar localidades prioritárias para o desenvolvimento de ações de vigilância e controle. MÉTODOS : A área de estudo constituiu-se dos 316 municípios do estado de São Paulo pertencentes às cinco regiões de saúde com ocorrência da leishmaniose visceral americana em humanos, utilizando os casos autóctones e óbitos, com ano de notificação e município de ocorrência. Calcularam-se taxas de incidência e de mortalidade e letalidade por município, por região e para a área de estudo. Utilizaram-se o estimador bayesiano empírico para obtenção de taxas de incidência e de mortalidade bayesianas locais para cada município e a krigagem para visualização da distribuição espacial das temperaturas e das precipitações pluviométricas. RESULTADOS : Foram detectados 73 municípios com transmissão da doença. As primeiras ocorrências deram-se em áreas com maiores temperaturas e menores pluviosidades, mas sua disseminação também ocorreu em áreas menos quentes e mais úmidas. A expansão da leishmaniose visceral americana em humanos apresentou um eixo principal de disseminação no sentido noroeste para sudeste, acompanhando a rodovia Marechal Rondon e o gasoduto Bolívia-Brasil, e um eixo secundário, na direção norte-sul, acompanhando a malha rodoviária. As taxas de incidência, segundo regiões de saúde, apresentaram um pico seguido de queda, com exceção da região de São José do Rio Preto. Observou-se maior concentração de municípios com altas taxas de incidência e mortalidade nas regiões de saúde de Araçatuba, Presidente Prudente e Marília. CONCLUSÕES : Possíveis fatores determinantes da expansão da doença incluíram a rodovia Marechal Rondon e a construção do gasoduto Bolívia-Brasil. Fatores climáticos pareceram não ter papel determinante nessa expansão. O uso de técnicas de análise espacial permitiu identificar municípios com possível subnotificação de casos e óbitos e indicar municípios prioritários para o desenvolvimento de ações de vigilância e controle.

Population health diagnosis with an ecohealth approach

OBJECTIVE To analyze the characteristics of health diagnosis according to the ecohealth approach in rural and urban communities in Mexico.METHODS Health diagnosis were conducted in La Nopalera, from December 2007 to October 2008, and in Atlihuayan, from December 2010 to October 2011. The research was based on three principles of the ecohealth approach: transdisciplinarity, community participation, gender and equity. To collect information, a joint methodology and several techniques were used to stimulate the participation of inhabitants. The diagnostic exercise was carried out in five phases that went from collecting information to prioritization of problems.RESULTS The constitution of the transdisciplinary team, as well as the participation of the population and the principle of gender/equity were differentials between the communities. In the rural community, the active participation of inhabitants and authorities was achieved and the principles of transdisciplinarity and gender/equity were incorporated.CONCLUSIONS With all the difficulties that entails the boost in participation, the incorporation of gender/equity and transdisciplinarity in health diagnosis allowed a holistic public health approach closer to the needs of the population.

Immunoglobulins and C3 in the P. brasiliensis granuloma

The experimental model of paracoccidioidomycosis induced in mice by the intravenous injection of yeast-forms of P. brasiliensis (Bt2 strain; 1 x 10(6) viable fungi/animal) was used to evaluate sequentially 2, 4, 8, 16 and 20 weeks after inoculation: 1. The presence of immunoglobulins and C3 in the pulmonary granuloma-ta, by direct immunofluorescence; 2. The humoral (immunodiffusion test) and the cellular (footpad sweeling test) immune response; 3. The histopathology of lesions. The cell-immune response was positive since week 2, showing a transitory depression at week 16. Specific antibodies were first detected at week 4 and peaked at week 16. At histology, epithelioid granulomas with numerous fungi and polymorphonuclear agreggates were seen. The lungs showed progressive involvement up to week 16, with little decrease at week 20. From week 2 on, there were deposits of IgG and C3 around fungal walls within the granulomas and IgG stained cells among the mononuclear cell peripheral halo. Interstitital immunoglobulins and C3 deposits in the granulomas were not letected. IgG and C3 seen to play an early an important role in. the host defenses against P. brasiliensis by possibly cooperating in the killing of parasites and blocking the antigenic diffusion.

Avaliação em camundongo da eficácia do antiveneno administrado no local da inoculação intramuscular do veneno de Crotalus durissus terrificus

A eficácia do antiveneno crotálico por via intramuscular (im) no local da inoculação, também im, do veneno de Crotalus durissus terrificus foi avaliada em camundongos. Em três experimentos inocularam-se duas DLSO do veneno por via im e administrou-se o antiveneno de três formas: metade da DE50 por via intraperitoneal (ip) e metade por via im, no mesmo local, imediatamente após (1º) e 30' após (2º) a inoculação do veneno; quatro quintos de DE50 por via ip e um quinto por via im, no mesmo local e 30' após a inoculação do veneno (3º). O antiveneno ofereceu, por via ip, maior proteção aos camundongos (menor taxa de óbito em 48 horas) do que quando foi administrado, em parte, por via im, no local da inoculação do veneno (p<0,05). Infere-se, portanto, que esta via não deve ser rotineiramente utilizada em seres humanos picados por serpente.

Vibrios among patients of good socioeconomic conditions during the cholera epidemic in Recife, Brazil

Between March and July, 1992, we screened for Vibrio all fecal samples submitted for bacteriologic diagnosis at a private clinical laboratory in Recife. Of 1435 cultures examined only 1 (0.07%) was positive for V.cholerae 01, biovar Eltor, serovar Inaba, but 17 (1.2%) yielded non-cholera Vibrio (V.cholerae non-01; V.fluvialis; V.furnissii, V.parahaemolyticus and Vibrio spp). Thus, V.cholerae 01, differently of other enteropathogenic vibrios, spared individuals of good socioeconomic conditions even during the cholera epidemic, which made hundreds of victims in the neighboring slums.

Evaluation of the double diffusion, enzyme immunoassay and immunoblotting techniques, for the diagnosis of human hydatid disease in tropical areas

Hydatid disease in tropical areas poses a serious diagnostic problem due to the high frequence of cross-reactivity with other endemic helminthic infections. The enzyme-linked-immunosorbent assay (ELISA) and the double diffusion arc 5 showed respectively a sensitivity of 73% and 57% and a specificity of 84-95% and 100%. However, the specificity of ELISA was greatly increased by using ovine serum and phosphorylcholine in the diluent buffer. The hydatic antigen obtained from ovine cyst fluid showed three main protein bands of 64,58 and 30 KDa using SDS PAGE and immunoblotting. Sera from patients with onchocerciasis, cysticercosis, toxocariasis and Strongyloides infection cross-reacted with the 64 and 58 KDa bands by immunoblotting. However, none of the analyzed sera recognized the 30 KDa band, that seems to be specific in this assay. The immunoblotting showed a sensitivity of 80% and a specificity of 100% when used to recognize the 30 KDa band.

Avaliação da eficácia do antiveneno botrópico administrado no local da inoculação intramuscular do veneno de Bothrops jararaca: estudo experimental em camundongos

Foi determinada, em camundongos de 18 a 20 g, a dose efetiva 50% do antiveneno botrópico, por via intraperitoneal (ip), imediatamente (DE50 Oh) e 30 minutos (DE50 30') após a inoculação de 2 DL50 do veneno de B. jararaca, por via intramuscular (im). A DE50 30' foi três vezes maior do que a DE50 Oh. A eficácia do antiveneno administrado no local da inoculação do veneno foi avaliada inoculando-se duas DL50 do veneno, por via im, e administrando-se a DE50 do antiveneno imediatamente (DE50 Oh) e 30 minutos após (DE50 30'), de duas formas a saber: totalmente por via ip (1ª) e metade por via ip e metade por via im (2ª), no mesmo local da inoculação do veneno. O antiveneno ofereceu, por via ip, maior proteção aos camundongos (menor taxa de óbito em 48 horas) do que quando metade do mesmo foi administrado, por via im, no local da inoculação do veneno. Conclui-se que, neste modelo experimental, quando se inicia o tratamento tardiamente há necessidade de maior dose de antiveneno botrópico e que não há benefício em administrá-lo no local da picada.

Dos moluscos que apresentaram positividade para diversas larvas de trematódeos, quatro exemplares de B. tenagophila estavam positivos para S. mansoni.

Aspergillosis in immunocompromised children acute myeloid leukemia and bone marrow aplasia.: Report of two cases

Two cases of Aspergillosis in immunocompromised children are reported. Both were caused by Aspergillns flavus. Early diagnosis and treatment led to the remission of the process. One patient had acute myeloid leukemia; the fungus was isolated from the blood. The other patient with bone marrow aplasia, presented an invasive aspergillosis of the paranasal sinuses with dissemination of fungal infection; the diagnosis was obtained by histology and culture of biopsied tissue from a palatal ulceration.

Bacterial agents isolated from cerebrospinal fluid of patients with Acquired Immunodeficiency Syndrome (AIDS) and neurological complications

Cerebrospinal fluid (CSF) samples from 2083 patients with acquired immunodeficiency syndrome (AIDS) and neurological complications were bacteriologically examined during a period of 7 years (1984-1990). The percentage of patients who had at least one bacterial agent cultured from the CSF was 6.2%. Mycobacterium tuberculosis was the most frequently isolated agent (4.3%), followed by Mycobacterium avium complex or MAC (0.7%), Pseudomonas spp (0.5%), Enterobacter spp (0.4%), and Staphylococcus aureus (0.3%). Among 130 culture positive patients, 89 (68.5%) had M. tuberculosis and 15 (11.6%) had MAC. The frequency of bacterial isolations increased from 1988 (5.2%) to 1990 (7.2%), partly due to the increase in MAC isolations. Bacterial agents were more frequently isolated from patients in the age group 21-30 years and from women (p<0.05).

Human parvovirus B19 infection: clinical and epidemiological study of 24 cases

From March 1994 to November 1995 24 cases of human parvovirus B19 infection were seen at the Infectious Diseases Department of the Hospital Universitário Antônio Pedro, Niterói - RJ. Serum samples for IgM detection (capture enzyme immunoassay) were positive from the 1st to the 27th day after the onset of the exathema. The classical features of erythema infectiosum (slapped cheecked syndrome) were observed in 8 (33.3%) cases all of them children. Eight patients (6 adults and 2 children) presented a symmetrical polyartropathy, seen more frequently in women. These results show that B19 infection diagnosis is difficult when the disease does not present the classical features and because of the frequent involvement of the joints this infection should be considered in the differential diagnosis of early rheumatoid arthritis.

Human papillomavirus genotypes in women with cervical cytological abnormalities from an area with high incidence of cervical cancer

It has been well demonstrated the relationship between the infection with high-risk human papillomavirus (HPVs) genotypes and cervical cancer. In Northeastern Argentina a high incidence of this pathology has been described and therefore a high prevalence of HPV infection is expected. In order to identify HPV genotypes associated with malignant and pre-malignant cervical lesions present in the area, 53 ecto-endo cervical cell specimens obtained from women with cytohistological alterations were studied by a PCR-RFLP technique. Out of 53 patients, 34 (64.2%) were positive for HPV infection, being HPV-16 (32.3%) the most frequently found genotype, followed by HPV-58 (14.7%), -6, -18 and -45 (5.9%), -33, -52, -53, -54, -56, -66, -MM4 and -LVX100 (2.9%). Also 5 cases of infection caused by multiple genotypes were found, which corresponded to 14.7% of the positive cases. Results indicate that besides HPV-16 and -18, the most prevalent high-risk HPV genotypes worldwide, others like -45 and -58 as well as co-infection cases are frequent between women of Northeastern Argentina, and a particular attention should be paid to this circumstance because it could be an epidemiological feature of regional importance and a useful information for a future vaccination program.

Strain differentiation of Trichophyton rubrum by random amplification of polymorphic DNA (RAPD)

Trichophyton rubrum is an important cause of dermatomycoses. Molecular strain typing methods have recently been developed to address questions about epidemiology and source of relapse following treatment. This report describes the application of RAPD for molecular strain differentiation of this fungus utilizing the primers 1- (5'-d[GGTGCGGGAA]-3') and 6- (5'-d[CCCGTCAGCA]-3'). A total of five RAPD patterns were observed among 10 strains of T. rubrum, with each of the primers used. We conclude that RAPD analysis using primers 1 and 6 can be used in epidemiological studies.
