Patologia do Coração na AIDS. Estudo de 73 Necropsias Consecutivas

Purpose - To study the incidence and the etiology of the cardiac lesions in AIDS patients. Methods - The autopsy protocols and the filled slides of the heart from 73 consecutive AIDS patients were reviewed. There were, at least, 2 slides of each heart stained by haematoxylin-eosin; when indicated, Ziehl-Nielsen, Gram and Gomori Grocott stains were used. Results - No cause of death was assigned to the heart. There was involvement of the heart in 66 (90%) cases. Marked atrophy of cardiac fibers with or without lipomatosis was observed in 38 patients. Interstitial infiltrates of myocardium were present in 38 necropsies and in 13 of these cases a probable pathogen was demonstrated: cryptococcus neoforms in three cases and mycobacteria tuberculosis, atypical mycobacteria, toxoplasma gondii, trypanosoma cruzi and cytomegalovirus in two cases each. Bacterial endocarditis was found in 4 autopsies and Kaposi sarcome in one. The pericardium was involved in 22 cases; in 12 there was only non specific mononuclear infiltration. Conclusion - Autopsy examination of the heart from AIDS patients revealed frequent pathologic involvement.

Avaliação da resposta à quimioterapia primária em amostra de mulheres brasileiras com tumores de mama localmente avançados

PURPOSE: to evaluate the loco-regional response to primary chemotherapy in patients with breast cancer at stages II and III. METHODS: a retrospective and analytical clinical study carried out in 97 patients with an average age of 52.2 years old, with breast cancer at stages II and III, attended from January 1993 to December 2004, and submitted to 3 to 4 cycles of primary chemotherapy with 5-fl uorouracil - 500 mg/m2, epirubicin - 50 mg/m2 and cyclophosphamide - 500 mg/m2 or doxorubicin - 50 mg/m2 e cyclophosphamide - 500 mg/m2, and then to loco-regional surgical conservative or radical surgical treatment. Chi-square and Fisher's exact tests were used to study the association among the variables (age, menopausal state, pre-chemotherapy tumoral volume, axillary condition, stage, therapeutic scheme and number of cycles), while Pearson's correlation coefficient was used for the quantitative variables (tumoral volume according to the anatomo-pathological study and the post-chemotherapy clinical tumoral volume. The significance level was 5%. RESULTS: there were 56.8% of cases at stage II and 43.2% at stage III. Approximately 50% of the patients received FEC50 and 50% AC. Objective clinical response with primary chemotherapy was obtained in 64.9% of the cases. Full clinical response occurred in 12.3% of patients, while full pathological response occurred in 10.3% of the cases. CONCLUSIONS: there was a statistically significant correlation between the number of cycles and the response to primary chemotherapy. Patients who received 4 cycles had better response than those who received 3 cycles. There was also a statistically significant concordance between the evaluation through clinical examination of the response to primary chemotherapy and the pathological findings. No statistically significant correlation was observed concerning age, menopausal status, tumoral volume, and pretreatment of axillary damage.

Patologia clínica em aves de produção - Uma ferramenta para monitorar a sanidade avícola - Revisäo

Clinical pathology has been used in veterinary medicine for many years to evaluate metabolic changes that may indicate any sign of disease in animals. Even though the use of blood parameters is routine in companion animals, it is not commonly used for avian clinical evaluation either wild or production birds. Among others, the lack of information of avian blood reference values has limited the use of this tool in avian medicine. The blood parameters in avian medicine are helpful to evaluate aspects related to animal health for wild and also production birds. Thus, this review paper presents some ways to use clinical pathology parameters to evaluate and to monitor the avian health.

Síndrome metabólica em mulheres na pós-menopausa tratadas de câncer de mama

PURPOSE: To assess the occurrence of metabolic syndrome (MetS) in postmenopausal breast cancer survivors. METHODS: A total of 158 breast cancer survivors were included in this cross-sectional study. Eligibility criteria were: women with amenorrhea >12 months and age ≥45 years, treated for breast cancer and no metastasis for at least five years. Clinical history and anthropometric indicator data (body mass index (BMI), and waist circumference, (WC) were collected. Biochemical parameters, including total cholesterol, HDL, LDL, triglycerides (TG), glucose and C-reactive protein (CRP), were measured. MetS was diagnosed as the presence of at least three of the following diagnostic criteria: WC>88 cm, blood pressure≥130/85 mmHg, triglycerides≥150 mg/dl, HDL <50 mg/dL,and glucose≥100 mg/dL. The Student's t-test and χ 2 test were used for statistical analysis. RESULTS: The mean age of breast cancer survivors was 63.1±8.6 years, with a mean follow-up of 9.1±4.0 years. MetS was diagnosed in 48.1% (76/158) and the most prevalent diagnostic criterion was abdominal obesity (WC>88 cm), affecting 54.4% (86/158) of the women. The patients without MetS had a longer follow-up compared those with MetS (p<0.05). Regarding the current BMI, PN average, those without MetS were overweight, and those with MetS were obese (p<0.05). Among the latter, comparison of BMI at the time of cancer diagnosis and current BMI (27.8±5.4 versus 33.4±5.4 kg/m2) showed a significant weight gain (p<0.05). Mean CRP values were higher in women with MetS (p<0.05). In the comparison of tumor characteristics and cancer treatments there was no difference between groups (p>0.05). CONCLUSION: Postmenopausal breast cancer survivors had a higher risk of developing metabolic syndrome and central obesity.
