Auricular and laryngeal chondritis in nursery and finishing pigs.

This work aimed to characterize the clinic-pathological presentation of an outbreak of auricular and laryngeal chondritis in pigs. Visits were made to pig farms, where the clinical history was obtained, and clinical and postmortem examinations were performed. In those farms, 3% to 4% of pigs presented otohematomas, which started in the nursery and extended to the finishing phase. Moreover, some finishing pigs presented with respiratory distress, initially characterized as inspiratory dyspnea, associated by an uncommon respiratory stridor and culminating in death. Grossly, nursery piglets had enlarged ears, and on the cut surface, the cartilage was fragmented and associated with blood clots. In the finishing phase, in addition to auricular lesions, the epiglottis and arytenoid cartilages were thickened and distorted, which partially occluded the lumen. Microscopically, the laryngeal and auricular cartilages were fragmented, displayed a loss of matrix basophilia, and were surrounded by lymphohistiocytic inflammatory infiltrate, with occasional multinucleated giant cells and fibrosis. The lesions exclusively affected elastic cartilages. The disease in finishing pigs led to increased mortality and was a differential diagnosis to respiratory challenges. It was not possible to determine the factor that triggered this condition; however, a nutritional association is suspected. To the authors' knowledge, this is the first report of primary auricular and laryngeal chondritis in pigs.

Hiponatremia severa por meningitis tuberculosa: complicación frecuente pero olvidada

Se presenta el caso de un paciente varón de 55 años que ingresó por alteración del estado de conciencia por una hiponatremia severa secundaria a una meningitis tuberculosa. No hubo mejoría de la hiponatremia al tratamiento con solución salina hipertónica, por lo cual se planteó el diagnóstico de síndrome de secreción inapropiada de hormona antidiurética (SIADH) y se evidenció mejoría con la restricción hídrica. El interés del presente caso es reportar una complicación frecuente pero olvidada de la meningitis tuberculosa.

We present the case of a 55-year-old male patient who was admitted due to an altered state of consciousness due to severe hyponatremia secondary to tuberculous meningitis. There was no improvement in hyponatremia after treatment with hypertonic saline solution, therefore the diagnosis of syndrome of inappropriate secretion of antidiuretic hormone (SIADH) was proposed, and improvement was evidenced with fluid restriction. The interest of this case is to report a common but forgotten complication of tuberculous meningitis.

The effects of pharmacist interventions on health outcomes in patients with advanced prostate cancer in Brazil

Abstract This study examined the effects of pharmacist interventions for patients with advanced prostate cancer. A pre-post study was conducted between October 2014 and August 2017 in a community pharmacy in Brazil for outpatients with advanced prostate cancer, aged ≥ 18 years, using cyproterone acetate and/or goserelin. The patients had face-to-face meetings with a pharmacist who dispensed antiandrogenic drugs and performed interventions aimed at solving and/or preventing drug-therapy problems. Primary outcomes regarding prostate-specific antigen (PSA) and testosterone levels were compared at 0, 6, and 12 months, whereas secondary outcomes-medication adherence and quality of life-were compared at baseline and at the 12-month follow-up. Medication adherence was assessed using the Morisky-Green test, and quality of life was measured by the Medical Outcomes Study 36-item Short Form (SF-36) and the Functional Assessment of Cancer Therapy-Prostate (FACT-P). The analysis included 20 patients; 311 drug-therapy problems were identified and most of them were related to adverse reactions (78.5%). The most common adverse reactions were reduced libido, erectile dysfunction, hyperglycemia, fatigue, and gynecomastia. Testosterone levels significantly decreased at 6 months, and PSA levels at 6 and 12 months. No significant changes in adherence were noted at the end of the study. A significant increase in the "pain" domain and an improvement trend in the "physical aspects" and "vitality" domains were observed based on the SF-36 instrument. The findings show that pharmacist interventions were able to improve PSA and testosterone levels, and some domains of quality of life of patients.

Case report: Stepwise transition from subcutaneous treprostinil to epoprostenol in high-risk pulmonary arterial hypertension.

BACKGROUND: Idiopathic pulmonary arterial hypertension is associated with high morbidity and mortality. In recent years, the use of targeted therapies has led to an improvement in prognosis. Prostacyclin analogues treprostinil and epoprostenol require continuous subcutaneous or intravenous infusion and are generally administered in a stepwise approach. However, there are no clear recommendations for transition in high-risk patients requiring high doses of prostacyclin analogues. CASE SUMMARY: In this report, we describe the case of a 20-year-old woman under combined treatment with sildenafil, macitentan, and treprostinil who required transition from subcutaneous treprostinil therapy to intravenous epoprostenol due to erratic drug absorption and functional class progression. The transition was performed over 48 h in a stepwise approach reducing treprostinil dose 4 ng/kg/min every 3 h while increasing epoprostenol infusion 2 ng/kg/min until achieving a maintenance dose of 32 ng/kg/min. There were no side effects requiring changes in the infusion rate. DISCUSSION: Patients with advanced pulmonary arterial hypertension may necessitate switching from subcutaneous treprostinil to epoprostenol. Although many protocols have been used to date, there are no guidelines to direct this process safely. This 48-h scheme based on the pharmacokinetic properties of each drug was successful and well-tolerated.

Health profile of free-range wild boar (Sus scrofa) subpopulations hunted in Santa Catarina State, Brazil.

Wild boars represent a potential dissemination source of important pathogens to public and animal health, since they can host several pathogens. This study aimed to evaluate the health profile of wild boars hunted for population control in the state of Santa Catarina (SC), south of Brazil. For this study, tissue and blood samples were collected from 61 wild boars hunted from October 2017 to November 2018. All 61 serum samples were screened for antibodies by different assays, presenting the following seroprevalence: 52.4% for porcine circovirus type 2 (PCV2); 21.3% for Leptospira spp.; 19.7% for Mycoplasma hyopneumoniae; 13.1% for hepatitis E virus (HEV); and 9.8% for influenza A virus (IAV). No seroreaction was observed for Brucella spp. and classical swine fever virus (CSFV). At necropsy, the main lesions observed were evidence of pulmonary metastrongylid parasites, haemorrhagic lymph nodes and white-spotted liver. Histopathological analyses mainly showed interstitial pneumonia, bronchopneumonia and bronchi-associated lymphoid tissue (BALT) hyperplasia. There was a significant association between metastrongylid parasitism and BALT hyperplasia in lungs. Pathological findings of wild boars indicate that the assessed individuals were not exposed to notifiable diseases, such as CSFV, African swine fever virus and foot-and-mouth disease, which cause economic damage by non-tariff trade barriers. However, the detection of antibodies against PCV2 and M. hyopneumoniae, pathogens that impact commercial production, indicates the circulation of these agents, with frequency variation in wild populations. This shows the potential risk of pathogen transmission among domestic swine populations and free-living ones. The detection of antibodies against zoonotic agents such as HEV, IAV and Leptospira spp., other than characterizing the pathogens' circulation in these populations, suggests a potential risk to public health and pig farming, depending on the interactions established with the environment, humans and domestic swine.

Fenofibrate Increases the Population of Non-Classical Monocytes in Asymptomatic Chagas Disease Patients and Modulates Inflammatory Cytokines in PBMC.

Chronic Chagas disease cardiomyopathy (CCC) is the most important clinical manifestation of infection with Trypanosma cruzi (T. cruzi) due to its frequency and effects on morbidity and mortality. Peripheral blood mononuclear cells (PBMC) infiltrate the tissue and differentiate into inflammatory macrophages. Advances in pathophysiology show that myeloid cell subpopulations contribute to cardiac homeostasis, emerging as possible therapeutic targets. We previously demonstrated that fenofibrate, PPARα agonist, controls inflammation, prevents fibrosis and improves cardiac function in a murine infection model. In this work we investigated the spontaneous release of inflammatory cytokines and chemokines, changes in the frequencies of monocyte subsets, and fenofibrate effects on PBMC of seropositive patients with different clinical stages of Chagas disease. The results show that PBMC from Chagas disease patients display higher levels of IL-12, TGF-ß, IL-6, MCP1, and CCR2 than cells from uninfected individuals (HI), irrespectively of the clinical stage, asymptomatic (Asy) or with Chagas heart disease (CHD). Fenofibrate reduces the levels of pro-inflammatory mediators and CCR2 in both Asy and CHD patients. We found that CHD patients display a significantly higher percentage of classical monocytes in comparison with Asy patients and HI. Besides, Asy patients have a significantly higher percentage of non-classical monocytes than CHD patients or HI. However, no difference in the intermediate monocyte subpopulation was found between groups. Moreover, monocytes from Asy or CHD patients exhibit different responses upon stimulation in vitro with T. cruzi lysates and fenofibrate treatment. Stimulation with T. cruzi significantly increases the percentage of classical monocytes in the Asy group whereas the percentage of intermediate monocytes decreases. Besides, there are no changes in their frequencies in CHD or HI. Notably, stimulation with T. cruzi did not modify the frequency of the non-classical monocytes subpopulation in any of the groups studied. Moreover, fenofibrate treatment of T. cruzi-stimulated cells, increased the frequency of the non-classical subpopulation in Asy patients. Interestingly, fenofibrate restores CCR2 levels but does not modify HLA-DR expression in any groups. In conclusion, our results emphasize a potential role for fenofibrate as a modulator of monocyte subpopulations towards an anti-inflammatory and healing profile in different stages of chronic Chagas disease.

Potentially inappropriate prescribing and associated factors in elderly patients at hospital discharge in Brazil: a cross-sectional study.

Background The Screening Tool of Older Persons' Prescriptions/Screening Tool to Alert doctors to Right Treatment (STOPP/START) criteria is used to identify instances of potentially inappropriate prescribing in a patient's medication regimen. Objective To determine the prevalence and predictors of potentially inappropriate medications (PIMs) and potential prescribing omissions (PPOs) among elderly patients at hospital discharge. Setting A university hospital medical clinic in Brazil. Method Discharge prescriptions were examined using the STOPP/START criteria. Subjects were inpatients aged ≥60 years receiving at least one medication prior to hospitalization and with a history of cardiovascular disease. The prevalence of PIMs and PPOs was determined and a multivariable binary regression analysis was performed to identify independent predictors associated with PIMs or PPOs. Main outcome measure Prevalence of PIMs and PPOs. Results Of the 230 subjects, 13.9% were prescribed at least one PIM. The most frequently prescribed PIMs were glibenclamide or chlorpropamide prescribed for type 2 diabetes mellitus (31.0%), and aspirin at doses >150 mg/day (14.3%). Ninety patients had at least one PPO (39.1%). The most prevalent PPOs were statins (29.8%) and antiplatelet therapy (13.7%) for diabetes mellitus when coexisting major cardiovascular risk factors were present. No predictors for PIMs were found. In contrast, diabetes was a risk factor while dyslipidaemia was a protective factor for PPOs. Conclusion PIMs and PPOs commonly occur with elderly people at hospital discharge. Diabetes and dyslipidaemia were significantly associated with PPOs. Our findings show the need for interventions to reduce potentially inappropriate prescribing, such as a pharmacist medication review process at hospital discharge.

Exposure to potentially inappropriate medications in Brazilian elderly outpatients with metabolic diseases

ABSTRACT Management of pharmacotherapy in elderly with metabolic diseases is challenging and potentially inappropriate medications (PIMs) are risk factors for drug interactions and adverse events. The exposure to PIMs in elderly outpatients with metabolic diseases and its relationship with polypharmacy and other variables was investigated. PIMs prescribed to 207 elderly patients (aged 60 to 96 years) with metabolic diseases who attended a University Hospital of Sao Paulo city, Brazil, from April/2010 to January/2011, were evaluated. PIMs were detected using both 2003 Beers and 2008 STOPP criteria. The association between PIMs and age, gender and polypharmacy was also examined. 2008 STOPP criteria detected more PIMs (44.4 %) than 2003 Beers criteria (16.0%, p<0.001). Beers detected mainly PIMs antihypertensive (clonidine, 20.0%; doxazosin, 10.0%) and antidepressant (fluoxetine, 15.0%; amitriptyline, 10.0%) PIMs. Medicines used for cardiovascular (aspirin, 53.7%) and endocrine system (glibenclamide, 21.3%) were PIMs more frequently detected by 2008 STOPP. Unlike age and gender, polypharmacy increased the risk of PIMs by both 2003 Beers (OR: 4.0, CI95%: 1.2-13.8, p<0.031) and 2008 STOPP (OR: 6.8, CI95%: 3.0-15.3, p<0.001). Beers and STOPP criteria are important tools to evaluate the exposure to PIMs, which is strongly associated with polypharmacy in elderly outpatients with metabolic diseases.

Dyslipidemia in young patients with type 1 diabetes mellitus.

OBJECTIVE: The association between type 1 diabetes mellitus (T1D) and dyslipidemia (DLP) increases the risk of cardiovascular disease (CVD). The aim of this study was to evaluate the presence of dyslipidemia in young T1D patients. MATERIALS AND METHODS: The study design was cross-sectional and descriptive. We reviewed medical records of T1D patients followed at an endocrinology service, from 1998-2012. DATA COLLECTED: gender, actual age and age at diagnosis, duration of T1D since diagnosis, body mass index (BMI), pubertal stage, glycemic control (GC) determined by glycated hemoglobin (HbA1c), total cholesterol (TC), HDL, LDL, triglycerides (TG). To analyze lipid profile and metabolic control, we used the Brazilian Society of Diabetes Guidelines. RESULTS: Were included 239 T1D patients, 136 (56.9%) females; mean ± SD: actual age 15.7 ± 5.0 years and at T1D diagnosis 7.3 ± 3.9; T1D duration 10.6 ± 6.4 years, 86.6% puberty, 15.1% overweight. The prevalence of DLP was 72.5%, 63.3% females, 86.6% puberty, mean ± SD: actual age 15.4 ± 4.8 years and at T1D diagnosis 7.2 ± 4.1 years, duration of T1D 10.7 ± 6.1 years. We found high-CT in 56.7%, low-HDL = 21.7%, high LDL = 44.0%, high-TG = 11.8%. Between females with DLP, 83.5% was in puberty. We find correlation between the presence of DLP, a poor GC and BMC. CONCLUSION: We found a high prevalence of DLP in young patients with T1D, particularly in puberty females. Programs targeting the prevention of dyslipidemia should be adopted, especially for this group, in order to prevent/delay chronic complications and cardiovascular disease.

Os donos do pedaço: caracterização das populações de cães e gatos domiciliados no município de São Paulo / Kings of the Hill: Characterization of housed dog and cat populations in the City of Sao Paulo

Este livro é fruto do amadurecimento de uma parceria entre o Laboratório de Epidemiologia e Bioestatística (LEB), do Departamento de Medicina Veterinária Preventiva e Saúde Animal da Universidade de São Paulo e o Centro de Controle de Zoonoses (CCZ), gerência da Coordenação de Vigilância em Saúde (COVISA) da Secretaria de Saúde da Prefeitura de São Paulo. Desde a concepção deste trabalho, havia a necessidade da criação de um novo indicador para a estimativa das populações animais que possibilitasse o planejamento das ações de saúde animal no município de São Paulo, uma vez que o indicador utilizado até então (Paranhos, 2002), direcionado a caracterizar o município como um todo, ora condizente com a gestão do controle populacional e saúde animal centraliza dos no CCZ, não era suficiente para caracterizar as heterogeneidades da cidade. De fato, a partir de 2002, iniciou-se a descentralização das ações de saúde no município de São Paulo (PMSP, 2002) e, a partir de 2003, algumas ações de saúde animal passaram a ser desenvolvidas em nível local pelas Supervisões de Vigilância em Saúde (SUVIS).

Estratégias de vigilância de um acidente envolvendo planta industrial de produção de ácido sulfúrico / Surveillance strategies of an accident involving a sulfuric acid production plant

Após acidente ambiental em empresa produtora de ácido sulfúrico, realizou-se estudo transversal para investigação de sintomas respiratórios e irritativos na população. Aplicou-se questionário em amostra aleatória simples, em pessoas presentes no local no dia da ocorrência, no raio de 900 m do estabelecimento, considerando a direção dos ventos. Foi calculada a prevalência de sintomas segundo gradientes de 300 m e realizado teste de Chi-Quadrado para sintomas isolados e agregados. Os dados foram georreferenciados, e foi ponderada a densidade de sintomas por área. Nas 451 pessoas estudadas, o teste de Chi-Quadrado foi significativo para todos os sintomas, exceto chiado comparando gradientes de distância. Os sintomas agregados apresentaram as seguintes ODDS Ratio (OR): respiratórios altos (OR: 6,18; 2,10; 1,00); irritativos (OR: 6,06; 2,09; 1,00); respiratórios baixos (OR: 4,93; 2,08; 1,00); náuseas e dor de cabeça (OR: 4,66; 2,02; 1,00). Os autores encontraram maior densidade de sintomas nas proximidades da fonte emissora. O estudo contribuiu para desencadear medidas mitigadoras na empresa.

Following an environmental accident in a sulfuric acid production plant, a transversal study was made to investigate respiratory and irritative symptoms on the population. A questionnaire was applied to a simple random sample from people present until 900 meters from the plant by the time of the event, considering the winds' directions. The prevalence of symptoms and Chi-square test was made according to gradients of 300 meters. The density of symptoms per area, geo-referenced, was pondered. The Chi-square test was significant on the 451 people studied for all symptoms, except by wheezing, comparing gradients of distance. The grouped symptoms presented the following ODDS Ratio (OR): high respiratory (OR: 6.18; 2.10; 1.00); irritative (OR: 6.06; 2.09; 1.00); low respiratory (OR: 4.93; 2.08; 1.00); nausea and headache (OR: 4.66; 2.02; 1.00). The authors have found a major density of symptoms in the vicinities of the source. The study contributed to instigate mitigating measures in the company.

Pharmaceutic guidance to hypertensive patients at USP University Hospital: effect on adherence to treatment

This study was carried out in the outpatient unit of the Teaching Hospital of the University of São Paulo (USP), and studied the impact of an educational program aimed at improving hypertensive patients' compliance to treatment. Seventy five (75) hypertensive patients of both sexes took part in the study which had no age or race discrimination. Participants presented no other concomitant pathology, except obesity, diabetes and dyslipidemia. Forty one patients were allocated to an experimental group (EG). Experimental patients attended lectures on the use of medication and artery hypertension (AH) and received personal pharmaceutical guidance for nine months. The control group (CG) comprised 34 patients who did not attend lectures or receive pharmaceutical advice in this period. The results were assessed by means of serum levels of cholesterol and fractions of tryacylglicerol (TG), urine sodium and potassium, arterial pressure (AP), body mass index (BMI), waist-hip ratio (WHR), and also based on responses to a questionnaire focusing on AH and treatment. Patients who received the guidance showed a greater decrease in AP, TG and WHR, besides an increase of potassium excretion through urine. The experimental group also scored higher on the questionnaires compared to the CG. It was concluded that the educational process, applied under the conditions of the present study, improves clients' clinical response to antihypertensive treatment and should be included in therapeutic strategies of health care services dealing with hypertensive patients.

Este trabalho, realizado no ambulatório do Hospital Universitário da USP, estudou a repercussão de um programa educacional visando melhorar a adesão do paciente hipertenso ao tratamento. Participaram do trabalho 75 pacientes de ambos os sexos, sem discriminação de idade ou raça, sem outras patologias concomitantes, exceto obesidade, diabetes e dislipidemia. Quarenta e um pacientes assistiram palestras sobre uso de medicamentos e hipertensão arterial (HA), receberam orientação farmacêutica individualizada durante nove meses e foram denominados grupo experimental (GE); o grupo controle (GC), composto por 34 pacientes não assistiu palestras nem recebeu orientação farmacêutica, neste período. Os resultados foram avaliados por meio de níveis séricos de colesterol e frações, triacil-gliceróis (TG), sódio e potássio urinários, pressão arterial (PA), índice de massa corpórea (IMC), relação cintura/quadril (RCQ), além de respostas a questionário enfocando HA e tratamento. Verificou-se que os pacientes orientados apresentaram maior decréscimo da PA, TG e da RCQ, além de aumento da excreção urinária de potássio e do percentual de acertos em questionários, em relação ao GC. Concluiu-se que o processo educativo, utilizado nas condições deste estudo, melhora a resposta clínica do paciente ao tratamento anti-hipertensivo e deve fazer parte das estratégias terapêuticas de serviços de atendimento a pacientes hipertensos.

Orientação educacional do paciente hipertenso: efeito sobre a adesão ao tratamento / Educational guidance hypertension patient: effect on adhesion to medical treatment

A hipertensão arterial é uma doença crônica, caracterizada pelo aumento constante da pressão sangüínea acima da normalidade (140 mmHg para a sistólica e 90 mmHg para a diastólica). Tem alta prevalência, em geral assintomática e é determinada por diversos fatores como raça, hereditariedade, idade e hábitos de vida relacionados à alimentação e à prática de exercícios físicos. É um dos maiores fatores de risco de morbidade e mortalidade cardiovasculares no mundo todo, causando além dos sérios problemas relativos à saúde, alto custo social. A falta de adesão às recomendações que são dadas aos pacientes é uma das causas do insucesso no tratamento dos indivíduos hipertensos...
