Alzheimer's disease: an epidemiological analysis over the number of hospitalizations and deaths in Brazil.

BACKGROUND: Alzheimer's disease (AD) is a neurodegenerative condition characterized by impaired cognitive function. It results in high morbidity, including a large number of hospitalizations, and mortality, generating high costs to health systems. OBJECTIVE: The present epidemiological analysis evaluated the number of hospitalizations and deaths by AD as the main diagnosis in Brazil between 2010 and 2020. This endeavor should contribute to a better understanding of the disease and its implications. METHODS: The present analytical, observational, longitudinal, and retrospective study used data extracted from the Department of Informatics of the Brazilian Unified Health System (DATASUS, in the Portuguese acronym). The variables include the number of hospitalizations, the total cost spent, the average cost per hospitalization, the average length of hospital stay, the number of deaths during hospitalization, the mortality rate per hospitalization, sex, age group, region, and race. RESULTS: From 2010 to 2020, there were 188,811 deaths and 13,882 hospitalizations for AD, with a total expenditure of BRL 25,953,019.40 in hospitalizations. The average length of hospital stay was 25 days. Over the considered period, mortality, the number of hospitalizations, and the total cost increased while the average length of stay decreased. CONCLUSION: From 2010 to 2020, AD represented a large portion of hospital admissions, generating a significant cost to the health system and a large number of deaths. These data are important to undertake joint efforts to prevent hospitalizations of these patients in order to minimize impacts on the health system.

Intramedullary hemangioblastoma of the thoracic cord with a microsurgical approach: A case report and literature review.

Background: Spinal cord hemangioblastomas (HBs) account for 2-15% of all spinal cord neoplasms. They are the third most common primary intramedullary tumor (1-5%). Here, 72-year-old female presented with a thoracic intramedullary spinal HB that responded well to surgery. Case Description: A 72-year-old female presented with a 3-4 years of progressive paresthesias and paraparesis. On examination, she exhibited diffuse distal weakness of the lower extremities. The magnetic resonance scan showed an intramedullary expansive lesion at the T1-T2 level that markedly enhanced with contrast with both proximal and distal hydromyelia. Surgery included a C7 partial and T1-T2 total laminectomies performed under microscope visualization with intraoperative monitoring. At surgery, there was a well-documented cleavage plane between the tumor and the cord; excision was facilitated using the cavitron ultrasonic surgical aspirator device. Conclusion: Surgery is the gold standard treatment for treating/resecting HBs and should include utilization of an operating microscope and intraoperative monitoring.

Cenário das políticas públicas para hemocromatose hereditária no Brasil / Public policy scenario for hereditary hemochromatosis in Brazil

Resumo Hemocromatose hereditária (HH) é a doença genética mais comum em descendentes de europeus e sua epidemiologia em nosso país é incerta. Considerando o cenário das políticas públicas em HH no mundo contemporâneo, este artigo propõe uma reflexão sobre o tema, com objetivo de fazer uma revisão bibliográfica narrativa sobre a abordagem adotada para essa doença em países desenvolvidos e a nível nacional. Além disso, discute sobre o custo-benefício da incorporação do índice de saturação da transferrina (ST) e ferritina sérica (FS) no nosso sistema de saúde, com a finalidade de identificar a HH antes que surjam suas complicações, bem como seu rastreio em campanhas nacionais de prevenção. O valor gasto para o screening da HH com dosagem de ST e FS pelo Sistema Único de Saúde (SUS) é muito menor do que os custos gerados quando o dano por excesso de ferro já está estabelecido. Nos casos suspeitos de HH, deveria ser viabilizada pelo SUS a pesquisa da mutação genética para o gene HFE, que atualmente só está disponível de forma privada. Com essas medidas, modifica-se a história natural da doença, reduzindo a morbimortalidade dos portadores e custos ao sistema público de saúde.

Abstract Hereditary hemochromatosis (HH) is the most common genetic disease among European descendants and its epidemiology in Brazil is unclear. Considering the contemporary public policy scenario aimed at HH, this narrative bibliographic review reflects on the approach adopted for this disease at the national level in developed countries. It also discusses the cost-effectiveness of incorporating transferrin saturation (TS) and serum ferritin (SF) indexes in the Brazilian healthcare system for early HH identification, as well as its screening in national prevention campaigns. The amount spent on ST- and FS-based HH screening by the Brazilian National Health System (SUS) is much lower than the costs generated by the already established iron overload. In suspected cases, genetic mutation research of the HFE gene, which is currently only performed privately, should be made available by the SUS. These measures can modify the natural history, reducing HH morbidity and mortality and its costs to the public health system.

Streptococcus gallolyticus bacteremia detected in apheresis platelets and its link to colonic neoplasms

Introduction: Streptococcus gallolyticus belongs to theStreptococcus bovis complex, and it is a common bacterium colonizing the gastrointestinal tract. Its presence in the blood may suggest an underlying pathology such as a colonic neoplasm. We report herein a case of S. bovis bacteremia in an apheresis platelet donor, review similar cases in the literature, and suggest a flowchart for the management of similar cases in other blood donation centers. Case Presentation: A 61-year-old subject presented to a Hemotherapy Service to make an apheresis platelet donation. On quality control testing, S. gallolyticus was identified in hemoculture, and the donor was called back for follow-up. At first, a new hemoculture was requested, and the patient was referred to the outpatient department of infectious diseases to further investigate pathologies associated with S. gallolyticus. A subsequent colonoscopy investigation evidenced a polypoid structure in the ascending colon. Pathology reported the resected specimen as a low-grade tubular adenoma. Conclusion: Isolation of S. bovis in blood products requires further investigation and should be managed with precision by Hemotherapy Services. A standard protocol for the management of asymptomatic patients with S. bovis positive hemoculture, with the requests of a new blood culture, a colonoscopy, and an echocardiogram is crucial, as it may ensure early diagnosis and reduce morbidity and mortality.

Coarctation of the abdominal aorta associated with renovascular hypertension and incapacitating claudication: repair with iliac-birenal bypass and paving and cracking technique.

Coarctation of the abdominal aorta is a rare etiology of intermittent claudication and refractory hypertension. Treatment is complex and requires knowledge of several vascular reconstruction techniques. We report a case of aortic coarctation at the level of the renal arteries, describing its treatment and presenting a literature review. Female patient, 65 years old, with refractory hypertension since the age of 35, using five antihypertensive medications at maximum doses. Blood pressure was 260/180mmHg and she had disabling claudication (less than 20 meters). Computed tomography angiography showed a 4mm coarctation in the juxtarenal aorta, with circumferential calcification at the stenosis site, and tortuous infrarenal aorta. Hybrid repair was performed with an iliac-birenal bypass and implantation of an Advanta V12 stent at the stenosis site. The patient's postoperative course was satisfactory, she was free from claudication, and her blood pressure 60 days after surgery was 140/80mmHg, taking two antihypertensive medications.

Coarctação de aorta abdominal justarrenal associada à hipertensão renovascular e claudicação incapacitante: tratamento utilizando ponte ilíaco-birrenal e técnica "paving and cracking" / Coarctation of the abdominal aorta associated with renovascular hypertension and incapacitating claudication: repair with iliac-birenal bypass and paving and cracking technique

Resumo Coarctação da aorta abdominal é uma causa rara de claudicação de membros inferiores e hipertensão refratária. O tratamento é complexo e exige conhecimento de diversas técnicas de reconstrução vascular. Apresentamos um caso de coarctação ao nível das artérias renais, seu tratamento e revisão da literatura. Paciente feminina, 65 anos, com hipertensão refratária desde os 35 anos, utilizando cinco medicações anti-hipertensivas em dose máxima. Pressão arterial média de 260/180mmHg e claudicação incapacitante (menos de 20 metros) bilateral. Angiotomografia computadorizada demonstrou coarctação de aorta justarrenal de 4 mm de maior diâmetro, calcificação circunferencial no local da estenose e tortuosidade da aorta infrarrenal. Foi submetida a tratamento híbrido, com ponte ilíaco-birrenal e implante de stent Advanta V12 no local da estenose. A paciente evoluiu satisfatoriamente e, 60 dias depois da cirurgia, apresentava-se com uma pressão arterial de 140/80mmHg, em uso de apenas duas medicações anti-hipertensivas e sem claudicação.
