ABSTRACT Objective: We evaluated the kinetics of cytokines belonging to the T helper1 (Th1), Th2, and Th17 profiles in septic patients, and their correlations with organ dysfunction and hospital mortality. Methods: This was a prospective observational study in a cohort of septic patients admitted to the intensive care units (ICU) of three Brazilian general hospitals. A total of 104 septic patients and 53 health volunteers (controls) were included. Plasma samples were collected within the first 48 h of organ dysfunction or septic shock (0D), after seven (D7) and 14 days (D14) of follow-up. The following cytokines were measured by flow cytometry: Interleukin-1β (IL-1β), IL-2, IL-6, IL-8, IL-10, IL-12/23p40, IL-17, IL-21, tumor necrosis factor-α (TNF-α), granulocyte-macrophage colony stimulating factor (GM-CSF), granulocyte colony-stimulating factor (G-CSF). Results: IL-6, IL-8, G-CSF and IL-10 concentrations were higher in septic patients than in controls (p < 0.001), while IL-12/23p40 presented higher levels in the controls (p = 0.003). IL-6, IL-8 and IL-17 correlated with Sequential [Sepsis-related] Organ Failure Assessment (SOFA) D0, D1 and D3 (except for IL-6 at D0). IL-8 was associated with renal and cardiovascular dysfunction. In a mixed model analysis, IL-10 estimated means were lower in survivors than in deceased (p = 0.014), while IL-21 had an estimated mean of 195.8 pg/mL for survivors and 98.5 for deceased (p = 0.03). Cytokines were grouped in four factors according to their kinetics over the three dosages (D0, D7, D14). Group 1 encompassed IL-6, IL-8, IL-10, IL-1β, and G-CSF while Group 3 encompassed IL-17 and IL-12/23p40. Both correlated with SOFA (D0) (p = 0.039 and p = 0.003, respectively). IL-21 (Group 4) was higher in those who survived. IL-2, TNF-α and GM-CSF (Group 2) showed no correlation with outcomes. Conclusion: Inflammatory and anti-inflammatory cytokines shared co-variance in septic patients and were related to organ dysfunctions and hospital mortality.

RESUMO Analisou-se, por meio de simulação, o efeito do uso de quatro diferentes alternativas de volumosos durante o período da seca na rentabilidade de sistema de produção de leite com vacas F1 Holandês x Gir: 1) uso da cana-de-açúcar in natura (Saccharum officinarum L.) por três meses e silagem de milho (Zea mays L.) por três meses; 2) uso da silagem de milho durante seis meses; 3) uso da silagem de sorgo durante seis meses; e 4) uso da cana-de-açúcar in natura enriquecida com ureia e sulfato de amônio, durante seis meses. A referência zootécnica foi do rebanho composto por vacas F1 Holandês x Gir da Fazenda Experimental de Felixlândia (FEFX) da Empresa de Pesquisa Agropecuária de Minas Gerais (EPAMIG), localizada no município de Felixlândia-MG, região central do estado. O inventário com despesas, receitas e demais dados foram cadastrados no software CUSTO BOVINO LEITE 1.0, visando gerar os resultados para a análise de rentabilidade. A cana-de-açúcar in natura foi a alternativa volumosa com a melhor rentabilidade em sistema de produção de leite com vacas F1 Holandês x Gir, mesmo com um menor volume de leite produzido.

ABSTRACT It was analyzed, by means of simulation, the effect of using four different rougahge alternatives during the dry period on the yield of milk production system using F1 Holstein x Gir cows. The rougahge alternatives were, as follows: 1) use of fresh sugar cane (Saccharum officinarum L.) for three months and corn silage (Zea mays L.) for three months, 2) use of corn silage for six months, 3) use of sorghum silage for six months, and 4) use of fresh sugar cane enriched with urea and ammonium sulfate for six months. The F1 Holstein x Gir herd of the Experimental Farm Felixlândia (FEFX) of the Agricultural Research Corporation of Minas Gerais (EPAMIG), located in the municipality of Felixlândia, state of Minas Gerais, central region of the state was used as reference. The inventory expenses, revenue and other data were registered in CUSTO BOVINO LEITE 1.0 software, aiming to generate the results for the profitability analysis. Fresh sugar cane was the rougahge alternative with the best profitability in milk production system with F1 Holstein x Gir cows, even with a smaller volume of milk produced.

OBJETIVO: Avaliar a prevalência de transtornos psiquiátricos em pacientes com diagnóstico de enxaqueca crônica com e sem uso excessivo de medicação sintomática. MÉTODOS: Setenta e dois voluntários foram recrutados a partir de um Programa de Saúde da Família da comunidade de Paraisópolis, na cidade de São Paulo (SP). Esses pacientes foram submetidos a exames clínico e neurológico. As seguintes variáveis foram analisadas: idade, gênero, nível educacional, índice de massa corporal, tipo de uso excessivo de medicação, características da cefaleia, consumo de cafeína, presença de ansiedade e distúrbios de humor. RESULTADOS: Dos 72 pacientes, 50 (69%) tinham cefaleia crônica, com uso exagerado de medicação, e 22 (31%) tinham cefaleia crônica, sem uso excessivo de medicação. Os fatores idade, gênero, nível educacional, índice de massa corporal, tipo de uso excessivo de medicação, características da cefaleia e consumo de cafeína não mostraram diferença significante entre os grupos estudados. Os diagnósticos de ansiedade e de distúrbios de humor ao longo da vida foram mais comuns nos pacientes com uso excessivo de medicação (p=0,003 e p=0,045, respectivamente). CONCLUSÃO: Este estudo mostrou uma associação significativa entre cefaleia crônica e uso excessivo de medicação nos pacientes avaliados, quanto ao diagnóstico de transtornos de ansiedade e de humor ao longo da vida. Não foi encontrada nenhuma associação com outros distúrbios psiquiátricos pesquisados.

OBJECTIVE: To evaluate the prevalence of psychiatric disorders in patients diagnosed with chronic migraine with and without acute medication overuse. METHODS: Seventy-two volunteers were recruited from a Family Health Program of the Paraisópolis community in São Paulo (SP), Brazil. These patients were submitted to a detailed headache questionnaire. All participants were submitted to physical and neurological examinations. The following variables were analyzed: age, gender, education level, body mass index, type of overused medication, headache characteristics, and caffeine consumption, lifetime anxiety and mood disorders. RESULTS: Out of 72 patients, 50 (69%) had chronic migraine with medication overuse, and 22 (31%) had chronic migraine without medication overuse. Factors such as age, gender, education level, body mass index, type of overused medication, headache characteristics, and caffeine consumption were not significantly different between the two studied groups. Lifetime anxiety and mood disorders were more common in patients with acute medication overuse (p=0.003 and p=0.045, respectively). CONCLUSION: This study has shown a significant association among chronic migraine and medication overuse with lifetime mood and anxiety disorders in patients of the studied population. No association was found for other researched psychiatric disorders.

Neuralgia glossofaríngea com síncope como um sinal de câncer do pescoço é uma condição muito rara. Uma revisão da literatura revelou apenas 29 casos relatados anteriormente. Apresentamos o primeiro caso brasileiro de tal associação. Um homem de 68 anos se apresentou com dores paroxísticas insuportáveis no lado direito do pescoço, algumas vezes seguidas de síncope. Dada a suspeita de recidiva tumoral derivada de uma malignidade cervical tratada previamente, realizou-se um exame de tomografia computadorizada que evidenciou um tumor parafaríngeo direito. As dores e as síncopes foram controladas satisfatoriamente com carbamazepina e o paciente foi submetido à radioterapia paliativa.

Glossopharyngeal neuralgia with syncope as a sign of neck cancer is a very rare condition. A review of the literature revealed only 29 cases formerly reported. We present the first Brazilian case of such association. A 68-year-old man presented with paroxysmal excruciating pain over the right side of the neck, sometimes followed by syncope. Given the suspicion of recurrent tumor from a previously treated neck malignancy, a computed tomography scan was performed and a right parapharyngeal tumor was shown. Pain and syncope were successfully controlled with carbamazepine and the patient underwent palliative radiotherapy.
