Tuberculosis remains a serious public health problem, and in Brazil, the principal agent for this disease is the Mycobacterium tuberculosis. In infancy, among extrapulmonary forms, one of the most frequent and less studied is that involves the superficial lymph nodes. In order to determine the incidence and to know the epidemiologic, clinical and laboratory features of lymph nodes tuberculosis, between January, 1995 to December, 1996, in the attendance outpatient unit of Hospital Ofir Loiola, it was enrolled 73 children from both sexes, aged 0 to 14 years, with enlargement of the cervical lymph nodes. The samplewas divided in 2 groups: in the first group, it was located 61 patients with adenopathy from etiologies other than tuberculosis, while 12 patients with cervical tuberculosis adenopathy took part in the second group. In this study, concerning tuberculosis adenopathy, for one hundred thousand in habitants,in the metropolitan area of Belem, it was observed an year rate incidence of 1.03 . Regarding adenopathy from other etiologies, the incidence was 4.27 and 6.15, in 1995 and 1996, respectively. The great majority of childhood adenopathy (64.4%) was nonspecific, although, when it was considered just those of known etiology, the relative risk of being tuberculosis was1.17. In both groups, the greatest incidence of cervical adenopathy was observed among preschool male children. However, when it was made a comparative analysis between the groups, there were no statistic significative differences toward age, sex, nutritional status, clinical symptom onset, type and characteristics of the affected lymph nodes. Disturbance in the nutritional status may have played a role to enhance the morbidity in 41.7% of the tuberculosis cases. The evidence of a cervical mass was the main symptom in the 2 studied groups, though, 75.1% of children with lymph node tuberculosis also had a general involvement of other lymph nodes chains. All children with cervical lymph node enlargement, which proved later to be of tuberculosis etiology had at least one month of illness course, and in such circumstances, a cold abscess represented the main symptom in 25% of them. It was possible to identify the sourceof infection in 1/3 of patients. Among children with tuberculosis, 63.6% had a positive tuberculin skin test, with a reaction 210 mm. Considering all bacteriologic procedures performed, culture turned to be the main element to tuberculosis diagnosis, with 100% positive results; while baciloscopy had little importance. Histopatologic exams showed granulomatosis lesions suggesting tuberculosis, in 88.9% of the sample. Concomitant pulmonary involvement was observed in 27.3% of children with lymph node tuberculosis. A good therapeutic response was seen using the pattern scheme adopted by Health Ministery, with out adverse reactions.

Estudo clínico, morfológico e imuno-histoquímico de série de casos de tuberculose pleural e ganglionar
(Universidade Federal do Pará, 2011) LIMA, Edna Porfírio de; DEMACHKI, Samia; http://lattes.cnpq.br/7568391537270652; MONTEIRO, Maria Rita de Cassia Costa; http://lattes.cnpq.br/5536136455627983
The difficulty in definitive diagnosis of extra-pulmonary tuberculosis persists, mainly due to poor solutions available from conventional methods for detection of Mycobacterium tuberculosis. This study aimed to evaluate the contribution of immunohistochemical (IHC) for detection of Mycobacterium spp, in cases of pleural and lymph node tuberculosis with negative staining, as well as investigate some clinical, laboratory and morphological aspects of the disease. To obtain this sample was made in the pursuit of cases through surveillance (NVE) and Division of Medical Archives and Statistics (DAME), University Hospital João de Barros Barreto (HUJBB) and the Department of Pathology, University of Pará (UFPA), selecting those who had performed the histopathological examination for diagnosis of the case. Fifty patients were included, twenty-five with presumptive diagnosis of pleural tuberculosis and twenty-five of lymph node tuberculosis. To obtain the clinical and laboratory data were reviewed their medical records, and to confirm the morphological aspects review was performed of all selected slides. Thereafter, each sample was subjected to IHC with polyclonal Mycobacterium bovis BCG. It was found in the investigated group, more often male, whose average age was 33.8 years (SD: 14.1) with the majority coming from the city of Belem, Pará and education level of seven or fewer years of schooling. Constitutional symptoms more frequent in the whole group were fever and weight loss. In patients with pleural tuberculosis, the most frequent specific symptoms were cough, chest pain and dyspnea, and in those with lymph node involvement of the cervical alone was more frequent. Infection with human immunodeficiency virus (HIV) or Acquired Immune Deficiency Syndrome (AIDS) and alcohol consumption were the risk conditions most frequently associated. In pleural tuberculosis, 20% of cases presenting with pleural effusion associated with parenchymal injury, and 60% of the pleural fluid was exudate type. While in the lymph nodes in 50% of the cases revealed a parenchymal lesion on chest. This study was marginal participants in the amount of which has been held to direct research and culture for bacillus acid – resistant (AFB) in various clinical specimens analyzed (pleural fluid, pleural tissue and lymph node, sputum, and broncho-alveolar lavage). The predominant morphological pattern in both forms of the disease was tuberculous granulomas with caseous necrosis, regardless of serologic status for HIV. The IHC technique contributed to the diagnosis of pleural tuberculosis in 21% (4/19) samples of pleural tissue and 37.5% (9/24) of lymph node tissue. A positive immunohistochemical result defines the diagnosis of mycobacterial disease, and when associated with clinical, laboratory and morphological finds become a valuable tool to improve the diagnosis of extra-pulmonary tuberculosis.
