Influence of AIDS in collagen deposition and thickness of the bone marrow.

Bone marrow abnormalities are frequently observed in individuals with AIDS. Dysplasia, the most common abnormality, is found in more than 50% of patients infected with the HIV. The aim of this study was to assess trabecular thickness and collagen content as well as cellularity in the bone marrow of patients with AIDS. Sixty bone marrow samples were collected from the sternum of autopsied patients with or without AIDS (n = 30, each). Cellularity and trabecular thickness was assessed by performing hematoxylin-eosin staining; picrosirius staining was used to evaluate collagen content. Morphometric analyses were performed by using a Zeiss KS300 system (Kontron-Zeiss). Patients with AIDS showed a significant reduction in trabecular bone thickness and an increase in collagen deposition. No statistically significant differences were observed in cellularity between the 2 groups. Therefore, reduced thickness and increased collagen deposition were observed in the trabeculae of the bone marrow of patients with AIDS due to possible interaction between cytokines and bone marrow components.

Association between cysticercosis and neoplasia: a study based on autopsy findings.

Chronic infections including the cysticercosis induce inflammatory cells to produce free radicals and synthesize carcinogenic toxins. The cells with genetic mutations proliferate in a disorganized manner, leading to the development of neoplasia. The aim of the present study was to demonstrate the relation between cysticercosis and neoplasia. Patients autopsied were divided into 4 groups: patients with neoplasia and cysticercosis (NC), patients with neoplasia only (NN), patients with cysticercosis only (CC), and patients without neoplasia or cysticercosis (WW). Of 2012 autopsy reports analyzed, 0.4 showed NC. In groups CC and NC, the most common location of the parasite was the brain. There was a predominance of three or more cysticerci in groups NC and CC. In the NC group, all had malignant neoplasms, and was predominance of benign neoplasm in NN group. The digestive system was the most frequent neoplasia. By calculating odds ratio, rate of neoplasia in patients with cysticercosis was 0.74. In conclusion, the demographic profile of patients with cysticercosis and neoplasia is similar to that of patients with cysticercosis alone. The incidence of cysticercosis and neoplasia was greater in older patients suggesting that immunosenescence may contribute to development of neoplasia promoted by cysticercosis.

Analysis of strength and electromyographic activity of lower limbs of individuals with down syndrome assisted in physiotherapy and hippotherapy.

INTRODUCTION: one of the characteristics of Down Syndrome (DS) is muscle hypotonia. Different therapeutic approaches have a positive influence, between them Physiotherapy applications with different therapeutic approaches such as Hippotherapy have a positive effect on the physical health and quality of live of individuals with DS. OBJECTIVE: to evaluate the effects of both treatments on the strength and electromyographic activity of the lower limbs of children and adolescents with DS. METHODS: fourteen individuals, aged between 10 and 18 years, participated in two groups: Physiotherapy group (n = 5) and Hippotherapy group (n = 9). Thirty interventions were performed for each type of therapy, once a week, lasting 30 min. Pre and post-interventions, the 30-Second Chair Stand Test (30s-CST) was used to assess the strength of the lower limbs and the surface electromyography equipment (EMG 800RF) to assess the lower limb myoelectric activity. RESULTS: there was a reduction in the post-intervention electromyographic values for both treatments (p˂0.001), with significantly less myoelectric activity in Hippotherapy compared to Physiotherapy for all evaluated muscles (p˂0.001) and a significant increase in muscle strength for the Hippotherapy, post-intervention group (p = 0.0007). CONCLUSION: Physiotherapy and Hippotherapy are interventions that promote positive changes in the myoelectric activities of individuals with DS. However, only hippotherapy promoted an increase in strength of the lower limbs.

In situ expression of regulatory cytokines by heart inflammatory cells in Chagas' disease patients with heart failure.

Chagas' disease is caused by the protozoan parasite Trypanosoma cruzi. The immune system plays an important role in the reduction of parasite load, but may also contribute to the development of lesions observed during the chronic phase of the disease. We analyzed cytokines produced by inflammatory heart cells in 21 autopsy samples obtained from patients with Chagas' disease divided according to the presence or absence of heart failure (HF). Left ventricular sections were analyzed by immunohistochemistry using antibodies against human IL-4, IFN-γ, TGF-ß, TNF-α, and NOS2. In situ mRNA expression was quantified by a Low Density Array. The number of IFN-γ-positive cells was significantly higher than IL-4 positive cells. TNF-α, TGF-ß and NOS2 were detected in 65%, 62% and 94% of samples respectively. There was an association between TNF-α-producing cells and the presence of HF. Subjects with HF presented higher levels of STAT4 mRNA, whereas FoxP3 and STAT6 levels were similar in the two groups. A Th1 cytokine pattern predominated in the cardiac inflammatory cell infiltrate of Chagas' disease patients associated with HF. High degree of fibrosis was associated with low NOS2 expression. These results support the idea that Th1 immune responses are involved in heart lesions of Chagas' disease patients.

Kocher-Debré-Sémélaigne syndrome diagnosed by autopsy associated with disseminated intravascular coagulation.

Kocher-Debré-Sémélaigne syndrome is a rare disease with little literature, which develops with myopathy in infancy associated with neuromuscular alterations, polymyositis with symmetrical proximal muscle weakness, pseudohypertrophy, muscular rigidity and spasms, exercise intolerance, myxoedema, short stature, and cretinism. Male patient aged 18 years old, 1.52 m in height, admitted in the General Hospital of Triângulo Mineiro Federal University on November 11, 2003, complaining of intense diffuse abdominal pain like severe cramps, without triggering factors, associated with asthenia and hyporexia. This seems to be one of the few reports of KDS syndrome diagnoses by autopsy, where alterations in the thyroid gland connected with hypotrophy and probable congenital hypothyroidism were described and resulted in complications such as disseminated intravascular coagulation and hemophagocytic syndrome with fast progression to death of an 18-year-old patient.

Morphologic analysis of fetal stress organsin different causes of perinatal death.

Complications act as stress-inducers during pregnancy so the fetus can develop functional compensatory mechanisms or morphologic changes. The cases analyzed are with congenital malformations or acute stress; chronic included cases with ascending infection (AI) and perinatal hypoxia/anoxia (PHA). The hematoxylin-eosin (H&E) was done to analyze the vacuolization, and the immunohistochemistry to the phagocytosis. The discreet standard of vacuolization was observed in 52.6% of the cases, 22.1% moderate, and 25.3% severe. The number of macrophages was higher in PHA. Changes in these organs are closely related to the cause of death and to the period during which the harmful agent.

Macroscopic Evaluation of Atherosclerosis in the Arteries: An Autopsy Assessment Tool. / Avaliação Macroscópica da Aterosclerose nas Artérias: Uma Ferramenta de Avaliação na Autópsia.

BACKGROUND: Atherosclerosis, in some cases, is an asymptomatic condition, and it is important to know the degree of arterial impairment caused by plaques and its association with risk factors. Autopsy examination provides understanding of basic disease processes and assessment to data about macroscopic characteristic of atherosclerotic involvement. OBJECTIVE: To macroscopically assess and standardize atherosclerotic involvement of aorta, carotid and iliac arteries and compare with age, gender and causes of death. METHODS: We collected 53 aortic arteries, 53 right carotid arteries, 53 left carotid arteries, 53 right iliac arteries and 53 left iliac arteries. For this assessment, the extension of fatty streaks, atheromatous plaques, fibrosis and calcification were considered, being the reference to score the degree of atherosclerotic involvement. Many degrees of atherosclerosis and accurate values were observed for mild, moderate and severe classification. For statistical analysis, data were analyzed using the software GraphPad Prism® 7.0. Differences were considered statistically significant if p-value was less than 5% (p <0.05). RESULTS: Carotid arteries had greater atherosclerotic involvement compared to the other arteries (K = 15.73, p = 0.0004). Atherosclerosis was progressive and significant with increasing age (carotid arteries: t = 6.321; p <0.0001; aorta: U = 83.5; p <0.0001; iliac: U = 306; p <0.0001) and as cause of cardiovascular death (carotids: t = 5.047; p <0.0001; aorta: U = 98.5; p = 0.0068; iliac: U = 467.5; p = 0.0012). CONCLUSION: Macroscopic assessment of atherosclerosis is an innovative and low-cost way of direct visualization of atherosclerotic plaques, enabling an association with risk factors such as increasing age and cardiovascular diseases, providing important data for clinical practice.

FUNDAMENTO: A aterosclerose, em alguns casos, é uma condição assintomática, sendo necessário conhecer o grau de comprometimento arterial provocado pelas placas e sua associação com os fatores de risco. O exame de autópsia permite a compreensão dos processos básicos de doenças, assim como a avaliação e fornecimento de dados sobre a característica macroscópica do acometimento aterosclerótico. OBJETIVO: Avaliar macroscopicamente e padronizar o acometimento aterosclerótico das artérias aorta, carótidas e ilíacas e comparar com a idade, o sexo e a causa de morte. MÉTODOS: Foram coletados 53 artérias aorta, 53 artérias carótida direita, 53 artérias carótida esquerda, 53 artérias ilíaca direita e 53 artérias ilíaca esquerda. Para essa avaliação, foi considerada a extensão de estrias lipídicas, de placas ateromatosas, de fibrose e de calcificação, as quais serviram de referência para pontuar a intensidade do acometimento aterosclerótico. Foram observados vários graus da aterosclerose e valores acurados para a classificação discreta, moderada e acentuada. Para a análise estatística, os dados foram analisados utilizando-se o software GraphPad Prism ® 7.0. As diferenças foram consideradas estatisticamente significativas quando "p" foi menor que 5% (p<0,05). RESULTADOS: As artérias carótidas apresentaram maior acometimento aterosclerótico em comparação às outras artérias avaliadas (K=15,73, p=0,0004). A ocorrência da aterosclerose se mostrou progressiva e significativa com o decorrer da idade (carótidas: t=6,321; p<0,0001; aortas: U=83,5; p<0,0001; ilíacas: U=306; p<0,0001) e na causa de morte cardiovascular (carótidas: t=5,047; p<0,0001; aortas: U=98,5; p=0,0068; ilíacas: U=467,5; p=0,0012). CONCLUSÃO: A avaliação macroscópica da aterosclerose trata-se de uma forma inovadora e de baixo custo de avaliação através da visualização direta das placas ateroscleróticas, possibilitando uma associação com fatores de risco como idade avançada e doenças cardiovasculares, fornecendo dados importantes para a prática clínica.

Chagas disease and gynecologic neoplasias.

The inflammation caused by Trypanosoma cruzi produces irritation and cell proliferation and may contribute to the development of cancer. The objective was to determine the occurrence of gynecologic neoplasia (GN) and demographic characteristics in patients with Chagas disease (CD). We used protocols of 671 autopsies between 1976 and 2008. The patients were divided into 3 groups: with GN and CD, only with CD, and only with GN. The 2 diseases were observed in 4.5% of patients with a mean age of 47.6 years and who were predominantly white. The megaesophagus and megacolon were more frequent in the group with only CD. The most common benign neoplasm was uterine leiomyoma, and malignant, carcinoma of the cervix. We conclude that the epidemiological profile of patients with CD and GN was similar to the other groups, and the CD was found not to be a risk factor or protective against the development of GN.

Acute Chagas' disease in postrenal transplant and treatment with benzonidazole.

Transplanted organs may act as a route of transmission of infectious diseases, such as Chagas' disease. The aim of this study was to describe the transmission of the Trypanosoma cruzi through a renal transplant and the anatomo-clinical evolution of the patient after treatment with benzonidazole. The patient was a 31-year-old white male from the State of Minas Gerais in Brazil. He had renal failure secondary to diabetes and later received a kidney from a cadaveric donor. The patient was undergoing immunosuppression therapy with azathioprine, cyclosporine A, and prednisone. After the transplant, he developed an acute phase of Chagas' disease and complications from diabetes and died 2 months later. In the autopsy, T cruzi amastigotes were found in the transplanted kidney, heart, bladder, liver, and pancreas. An important reduction in the parasitemia was obtained through the treatment of the infection with benzonidazole; however, the patient died due to complications from diabetes associated with tissue lesions caused by T cruzi.

Analysis of mast cells and myocardial fibrosis in autopsied patients with hypertensive heart disease.

OBJECTIVE: To analyze the percentage of collagen fibers and mast cell density in the left ventricular myocardium of autopsied patients with and without hypertensive heart disease. METHODS: Thirty fragments of left ventricular myocardium were obtained from individuals autopsied at the Clinical Hospital of the Federal University of Triângulo Mineiro (UFTM) in the period from 1987 to 2017. Individuals were divided into two groups: those with hypertensive heart disease (HD) and those with no heart disease (ND). Subjects were also assessed according to age, gender and race (white and non-white). Collagen fibers were quantified by computed morphometry and mast cell density was assessed by immunohistochemical methods. RESULTS: There were significantly more collagen fibers in the left ventricle in the HD group than in the ND group (p<0.001). Mast cell density was significantly higher in the left ventricle of individuals with HD immunolabeled with anti-chymase and anti-tryptase antibodies (p=0.02) and also of those immunolabeled only with anti-tryptase antibodies (p=0.03). Analyzing the HD group, there was a significant positive correlation between the percentage of collagen fibers in the left ventricle and mast cell density immunolabeled by anti-chymase and anti-tryptase antibodies (p=0.04) and also mast cell density immunolabeled only with anti-tryptase antibodies (p=0.02). CONCLUSIONS: Mast cells are involved in the development of hypertensive heart disease, contributing to the remodeling of collagen fibers in this disease.

Electromyographic analysis of stomatognathic muscles in elderly after hippotherapy.

The aging process affects the entire human body, including the stomatognathic system, and can trigger not only occlusal but also postural imbalances involving other muscular chains. Hippotherapy has been used to promote cervical, postural, and balance control in individuals with diverse impairments. The present study used electromyography to evaluate the masseter and temporal muscles in an elderly population pre- and post-hippotherapy. Participants included 17 individuals, mean age 66,5±7 years. Electromyographic recording of the bilateral masseter and temporal muscles was performed during the postural resting condition and activities that involved the active participation of these muscles in different conditions. The practitioner performed no other type of activity or exercise during the intervention because the objective is to evaluate the effect of the three-dimensional movement provided by the horse. Raw electromyographic data were tabulated using commercially available software (IBM® SPSS® Statistics 234.0) and subjected to statistical analysis, in which p ≤ 0.05 was considered to be statistically significant. Post-hippotherapy, there was lower electromyographic activity for the masseter and temporalis muscles in all the static mandibular tasks, with significant effect for time for the right temporal muscle (p = 0.038), the left temporal muscle (p = 0.028) and in the all dynamic mandibular tasks for the left temporal muscle (p = 0.025) and the left masseter muscle (p = 0.027). Hippotherapy promotes a reduction in the myoelectric activity of the masticatory muscles of elderly individuals.

Impact of hippotherapy for balance improvement and flexibility in elderly people.

INTRODUCTION: The decrease in functional ability, strength, balance, flexibility, agility, and coordination owing to neurological and muscular changes is one of the characteristic features of the human aging process. Hippotherapy has been highlighted as a therapeutic approach with physical and psychological benefits for this section of the population. However, the effects of hippotherapy in elderly people need to be further studied by assessing their balance and flexibility. METHODS: Thirty elderly people were recruited and divided into two groups; 15 in the Hippotherapy Group (HG), and 15 in the control group (CG) (aged 66.07 ±â€¯5.80 and 68.47 ±â€¯5.85 years, respectively). The HG received ten 30-min sessions of hippotherapy once a week. Assessment included the Berg Balance Scale (BBS), the Timed Up and Go test (TUG), the Functional Reach Test (FRT)and the Sit-and-Reach Test with the Well's box before the first and after the tenth session of hippotherapy; and the Sit-and-Reach Test before and after each session. RESULTS: The HG demonstrated a significant difference in the TUG test execution time and the FRT scores before and after the hippotherapy sessions (p = 0.036, p = 0.030, respectively), indicating an improvement in functional range. The examination of flexibility with the Wells's box also revealed a significant difference in the rates (cm) before and after 10 sessions of the hippotherapy for the HG (p = 0.033). CONCLUSIONS: The present findings showthat hippotherapy improved elderly people's functional mobility, dynamic balance, and flexibility. These results will guide professionals who treat this population.

Administration of neural precursor cells ameliorates renal ischemia-reperfusion injury.

In this study we evaluated whether administration of stem cells of neural origin (neural precursor cells, NPCs) could be protective against renal ischemia-reperfusion injury (IRI). We hypothesized that stem cell outcomes are not tissue-specific and that NPCs can improve tissue damage through paracrine mechanisms, especially due to immunomodulation. To this end, Wistar rats (200-250 g) were submitted to 1-hour ischemia and treated with NPCs (4 x 10(6) cells/animal) at 4 h of reperfusion. To serve as controls, ischemic animals were treated with cerebellum homogenate harvested from adult rat brain. All groups were sacrificed at 24 h of reperfusion. NPCs were isolated from rat fetus telencephalon and cultured until neurosphere formation (7 days). Before administration, NPCs were labeled with carboxyfluorescein diacetate succinimydylester (CFSE). Kidneys were harvested for analysis of cytokine profile and macrophage infiltration. At 24 h, NPC treatment resulted in a significant reduction in serum creatinine (IRI + NPC 1.21 + 0.18 vs. IRI 3.33 + 0.14 and IRI + cerebellum 2.95 + 0.78 mg/dl, p < 0.05) and acute tubular necrosis (IRI + NPC 46.0 + 2.4% vs. IRI 79.7 + 14.2%, p < 0.05). NPC-CFSE and glial fibrillary acidic protein (GFAP)-positive cells (astrocyte marker) were found exclusively in renal parenchyma, which also presented GFAP and SOX-2 (an embryonic neural stem cell marker) mRNA expression. NPC treatment resulted in lower renal proinflammatory IL1-beta and TNF-alpha expression and higher anti-inflammatory IL-4 and IL-10 transcription. NPC-treated animals also had less macrophage infiltration and decreased serum proinflammatory cytokines (IL-1beta, TNF-alpha and INF-gamma). Our data suggested that NPC therapy improved renal function by influencing immunological responses.

Causes of death in older people autopsied.

Studies of causes of death in autopsied older people are not common in Brazil. The aims were to compare demographic data and causes of death in elderly people autopsied in the 1970s, 1980s, and 1990s and to relate causes of death to age, sex, color, and body mass index. Data survey of the autopsy reports came from the Hospital de Clínicas of the Universidade Federal do Triângulo Mineiro, Uberaba, Minas Gerais, Brazil. The data were obtained from the autopsied individuals 60 years or older. Median age was 69 years (60-120 years) and was higher in the 1990s than in the 1970s (70.5 vs 68.0, P < .05) and higher in women (70 vs 68 years, P < .05). Men (66.8%) and white people (70.0%) predominated during the period. The most frequent causes of death were cardiovascular (42%) and infectious (33.4%). The percentage of cardiovascular causes of death varied little over the 1970s (41.7%), 1980s (42.3%), and 1990s (42.9%), whereas that of infectious causes decreased (38.0%, 28.6%, and 28.6%, respectively) and that of neoplastic causes increased (10.3%, 12.6%, and 19.6%, respectively, P > .05). Most of the elderly (84.6%) presented a body mass index of less than 22 kg/m2 and malnutrition predominated in the 1980s (48%). Therefore, there was little percentage variation in cardiovascular-related deaths over the 3 decades while the percentage of neoplastic-related deaths increased. Infectious causes of death was associated with the lowest body mass index, and the greatest percentage of cardiovascular and neoplastic-related deaths were in women.

Analysis of the electromiographic activity of lower limb and motor function in hippotherapy practitioners with cerebral palsy.

OBJECTIVE: Investigation of the effects of hippotherapy treatment on lower limb muscle activity and gross motor function in subjects with cerebral palsy (CP), comparing them to a group of subjects with adequate motor development. METHODS: Evaluation was made of seven individuals with spastic diparetic CP, average age 9.3 (±3.3) years (CP group), Gross Motor Function Classification System (GMFCS) levels I and II, and eight individuals with adequate motor development, average age 10.9 (±3.2) years (control group). The groups were submitted to 25 sessions of hippotherapy, each lasting 30 min, on a weekly basis, and the muscle activity of the lower limbs was evaluated using surface electromyography during the 1st, 10th, 20th, and 25th sessions. For the CP group, Gross Motor Function Measurement (GMFM-88) was performed before and after hippotherapy treatment. RESULTS: There was higher muscle activity in the 10th session, compared to the other sessions, with greater activity of the tibialis anterior muscles, for both groups studied. After treatment, the CP group showed significant improvement in the GMFM total score, and in the scores for dimensions D and E. CONCLUSION: Hippotherapy sessions improved the muscle responses in both groups, and improved the gross motor function of the subjects with CP.

Immunological evaluation of vestibular folds in autopsies of patients with the acquired immunodeficiency syndrome.

UNLABELLED: Immune response cells are decreased in patients with the Acquired Immunodeficiency Syndrome. This alters the cell population in vestibular fold lymphoid follicles, leading to respiratory infections in these patients. Such infections are the main cause of mortality and morbidity in these patients. AIM: to characterize lymphoid follicle cell populations in the vestibular folds of adults with the Acquired Immunodeficiency Syndrome and associated or not respiratory infection. MATERIALS AND METHODS: A retrospective study was made of 64 adult larynges harvested during routine autopsies. Anti-B cell, Anti-CD3, Anti-CD68 and Anti-follicular dendritic cell antibodies were used for immunological testing. RESULTS: 46 (71.87%) of the sample patients had the Acquired Immunodeficiency Syndrome. In these patients, lymphoid follicle cellularity was lower compared to the control group. The cell number was decreased in patients with the Acquired Immunodeficiency Syndrome and associated respiratory tract infection. CONCLUSION: We demonstrated in this study that vestibular fold lymphoid follicles were affected by viral infections, and may be considered as a reliable marker of immunodepression in these patients.

Activation of lower limb muscles with different types of mount in hippotherapy.

OBJECTIVES: To analyze muscle activation of lower limbs (LL) of subjects in hippotherapy sessions. METHODS: The study included 10 healthy subjects, five male and five female, with an average age of 24.03 (±4.06) years. Subjects underwent four hippotherapy sessions of 30 min with interval of one week, and each session was performed with a different type of mount material in the following order: 1st performed with saddle and feet in the stirrups (S1), 2nd with saddle and feet off the stirrups (S2), 3rd with blanket and feet off the stirrup (S3) and 4th with blanket and feet in the stirrups (S4). Surface electromyographies were performed at 1, 10, 20 and 30 min of session, and the electrodes were placed on muscle bellies bilaterally on the muscles rectus femoris, vastus medialis, vastus lateralis and tibialis anterior. RESULTS: The analysis of muscle activity during these four sessions showed a significant difference in muscle recruitment in LL, and sessions with blanket and feet in the stirrups provided greater muscle activation of quadriceps and tibialis anterior with the horse at step gait (p = 0.0002). CONCLUSION: The results suggest that feet positioned in the stirrups is a relevant factor for greater muscle recruitment in LL to maintain postural balance while riding, especially using a blanket as mount material for ride a horse.

Width of sulcus and thickness of gyrus in patients with cerebral atherosclerosis: a new tool for the prevention of vascular cognitive impairment.

BACKGROUND AND PURPOSE: Cerebral atherosclerosis is the main cause of lesions that contribute to vascular cognitive impairment and vascular dementia, followed by arteriosclerosis of small vessels and cerebral amyloid angiopathy. The purpose of this study was to compare the post-mortem radiological alterations of autopsied adults with the macroscopic alterations in the posterior region of these brains in order to establish a relationship between the two forms of analysis and to discuss the relevance of the prevention of vascular cognitive impairment in patients with encephalic atherosclerosis. MATERIALS AND METHODS: Thirteen brains were analysed macroscopically to assess the degree of atherosclerosis of the basilar and the posterior cerebral arteries. The patients were autopsied in the Subject of General Pathology at General Hospital of Triângulo Mineiro Federal University in Uberaba, state of Minas Gerais, Brazil. The qualitative analysis of atherosclerosis was performed with classification into mild, moderate or severe. In the posterior region of the brains, width of sulcus and thickness of gyrus were measured by macroscopic analysis and by tomographic analysis. RESULTS AND CONCLUSIONS: There was a decrease in calcarine sulcus width and an increase in medial temporal occipital gyrus thickness in patients with a higher degree of atherosclerosis, macroscopically and in tomography, respectively. Low oxygenation caused by atherosclerosis probably leads to an encephalic parenchyma inflammation that causes microglial cells hypertrophy provoking increase in the gyrus thickness and decrease in the sulcus width, as observed in the present study.

Anatomopathological aspects of neurocysticercosis in autopsied patients.

The aim of this paper was to describe the occurrence and morphology of neurocysticercosis (NCC) in autopsies. We revised 2218 autopsies performed at the School Hospital from Federal University of Triangulo Mineiro, 1970-2003. Data referring to age, gender and color of patients were reported and NCC was microscopically and macroscopically analyzed. We found 53 (2.4%) NCC cases. The mean age was 50 years old, 34 (64.1%) individuals were male and 36 (67.9%) white. Macroscopically, 17 cysticerci were analyzed. The most frequent location was meningocortical in 12 (70.6%) cases. Microscopically, the cysticerci presented an ovoid shape, containing the larvae preserved in 4 (23.5%) cases or in destruction degrees in 13 (76.5%) cases. Therefore, in NCC was found several general pathologic processes (necrosis, interstitial deposits, fibrosis, gliosis, inflammation) amongst which are highlighted beta-fibrillose in 13 (76.5%) cases associated to inflammatory process in 16 (94.1%) cases caused by the parasite, not yet related to NCC, and calcification present in viable and destruction parasites.

Implications of alcoholic cirrhosis in atherosclerosis of autopsied patients.

INTRODUCTION:: Alcoholism is a major public health problem, which has a high social cost and affects many aspects of human activity. Liver disease is one of the first consequences of alcohol abuse, and steatosis, liver cirrhosis and hepatitis may occur. Other organs are also affected with pathological changes, such as pancreatitis, cardiomyopathies, dyslipidemias and atherosclerosis. OBJECTIVE:: To identify the occurrence and degree of atherosclerosis in alcohol-dependent individuals with liver cirrhosis, observing macroscopic and microscopic changes in lipid and collagen deposits and in the liver. We also aimed to verify the association of lipid and collagen fiber deposits with gender, age and body mass index, and to relate alcoholism, liver cirrhosis and atherosclerosis. METHOD:: We performed a study based on autopsy reports of patients with alcoholic liver cirrhosis, with analysis of aorta and liver fragments to verify the occurrence and degree of atherosclerosis, as well as collagen contents. RESULTS:: Microscopic atherosclerosis was higher in young subjects (early injury) and in patients with alcoholic liver cirrhosis. The macroscopic analysis of atherosclerosis in aortas showed that patients in more advanced age groups presented more severe classifications. Atherosclerosis, both micro and macroscopically, and the percentage of fibrosis in the liver and aorta were more expressive in females. CONCLUSION:: Cirrhotic patients presented a higher percentage of fibrosis and lipidosis, and may represent a group susceptible to the accelerated progression of cardiovascular diseases. Investigative studies contribute to targeting health-promoting interventions, reducing the mortality and costs of treating cardiovascular disease.
