RESUMO
BACKGROUND: Immunopreventable diseases are a public health reality in Brazil and worldwide, a reality that is not exclusive to children, but affects the adult population. OBJECTIVES: Discriminating the total costs of hospitalizations from immunopreventable diseases in the population aged 20 to 59 years. METHODS: A population, observational, descriptive, retrospective study was conducted with secondary information from DATASUS to discriminate the hospitalizations associated with immunopreventable diseases in Brazil and their care costs, within the Scope of the SUS, between 2008 and 2018, in the economically active population (20 to 59 years). RESULTS: It was analyzed 127,746 hospitalizations for immunopreventable diseases, (27.92% of all hospitalizations) were observed in the adult population, totaled R$115,682,097.54 (29.72% of the total costs). Of this population studied, 51.48% were registered as male; 66.74% were associated with influenza disease; 16.05% to chickenpox/herpes zoster infection and 7.55% to acute hepatitis B infections. The trend analysis of the time series of hospitalizations in this population showed a stationary trend. CONCLUSIONS: The 127,746 hospitalizations could be avoided with immunization, and 127,746 workers who could be working and not hospitalized. There were also R$115,682,097.54 that could be invested in other public health needs, which became necessary for the treatment of preventable diseases.

INTRODUCTION: The occurrence of the immunopreventable diseases in a population global reality. OBJECTIVE: To discriminate the direct costs of the hospitalizations from the immunopreventable diseases in the Unified Health System (SUS), in Brazil and their areas, between 2008 and 2018. METHODS: A population, observational, descriptive and retrospective study, with data from the information supplied by the DATASUS website, these data were collected during the 2019. RESULTS: It was identified 457,479 hospitalizations in the period; with a total of 2,450,870 days of hospital stay, with total costs of R$389,243,264.85. Only the disease mumps presented a growing tendency in whole areas; the chickenpox was decreasing; the illness whooping cough, yellow fever and tetanus were stationary in this period. CONCLUSIONS: The costs related to immunopreventable diseases were relevant in all the Brazil areas, with tendencies different between the geographic areas and between the several illnesses analysed.

INTRODUCTION: Development of technologies to reduce transfusion risks of infectious diseases is a major characteristic of hemotherapy. Thus, each donation undergoes clinical and serological screening tests to ensure the donated blood do not offer risks to the receiver. OBJECTIVE: Evaluate the prevalence of positive serology in blood donations rejected by Hemobanco (Curitiba - PR) in the period ranging from January 2003 to December 2012. METHODOLOGY: During the period studied, we observed the total number of donations and its division according to gender. We also analyzed the number of rejected donations due to seropositivity, considering the diseases investigated routinely in blood banks in Brazil, and the frequency of discards according to age groups. RESULTS: Within the period studied, 399,280 donations were performed. 62.0% donors were male. Comparing 2003 to 2012, we noticed a significant decrease of discards, from 10.2% to 5.0%, respectively. There was a reduction of seropositivity for HIV, HBsAg and anti-HBc and an increase for Chagas Disease, hepatitis C, syphilis and HTLV. The age group with the highest prevalence for discards changed: it used to be the 40-59 years old group in 2003, and became the 20-39 years old group in 2012. CONCLUSION: There was an increase in the number of donations in Hemobanco and a decrease in total discards due to seropositive donations. Most donors were male. The most prevalent cause of discards only amongst seropositive donation discards is seropositivity for anti-HBc. There was a significant increase of donors aged between 20 and 39 years old.

BACKGROUND: Because postlicensure surveillance determined that a previous rotavirus vaccine, RotaShield, caused intussusception in 1 of every 10,000 recipients, we assessed the association of the new monovalent rotavirus vaccine (RV1) with intussusception after routine immunization of infants in Mexico and Brazil. METHODS: We used case-series and case-control methods to assess the association between RV1 and intussusception. Infants with intussusception were identified through active surveillance at 69 hospitals (16 in Mexico and 53 in Brazil), and age-matched infants from the same neighborhood were enrolled as controls. Vaccination dates were verified by a review of vaccination cards or clinic records. RESULTS: We enrolled 615 case patients (285 in Mexico and 330 in Brazil) and 2050 controls. An increased risk of intussusception 1 to 7 days after the first dose of RV1 was identified among infants in Mexico with the use of both the case-series method (incidence ratio, 5.3; 95% confidence interval [CI], 3.0 to 9.3) and the case-control method (odds ratio, 5.8; 95% CI, 2.6 to 13.0). No significant risk was found after the first dose among infants in Brazil, but an increased risk, albeit smaller than that seen after the first dose in Mexico--an increase by a factor of 1.9 to 2.6 - was seen 1 to 7 days after the second dose. A combined annual excess of 96 cases of intussusception in Mexico (approximately 1 per 51,000 infants) and in Brazil (approximately 1 per 68,000 infants) and of 5 deaths due to intussusception was attributable to RV1. However, RV1 prevented approximately 80,000 hospitalizations and 1300 deaths from diarrhea each year in these two countries. CONCLUSIONS: RV1 was associated with a short-term risk of intussusception in approximately 1 of every 51,000 to 68,000 vaccinated infants. The absolute number of deaths and hospitalizations averted because of vaccination far exceeded the number of intussusception cases that may have been associated with vaccination.

Background: CYD-TDV (Dengvaxia®) was the first dengue vaccine approved, launched in Brazil in 2015 for individuals aged 9-44 years. We aimed to estimate the effectiveness of CYD-TDV in preventing symptomatic dengue cases during a campaign targeting individuals aged 15-27 years in selected municipalities in Paraná, Brazil. Additionally, we examined whether a history of dengue, as recorded by the surveillance system, modified the vaccine's effectiveness. Methods: We conducted a case-cohort analysis comparing the frequency of vaccination, with at least one dose of CYD-TDV, in individuals with dengue confirmed by RT-PCR, identified by the surveillance system during 2019 and 2020, with the vaccination coverage in the target population. Moreover, in a case-control design using weighted controls, we assessed the documented history of dengue as a modifier of the vaccine's effectiveness. We used a logistic random-effects regression model, with data clustered in municipalities and incorporating covariates such as the incidence of dengue before the campaign, age, and sex. We calculated vaccine effectiveness (VE) as (1-relative risk) x 100%. Findings: 1869 dengue cases were identified, which had a vaccination frequency significantly lower than the overall vaccination coverage in the target population (50.3% vs. 57.2%, respectively; overall VE: 21.3%; 95% confidence interval [CI]: 13.4%-28.4%). In individuals with a documented history of dengue, vaccination had a VE of 71% (95% CI: 58%-80%) in reducing the incidence of dengue. However, vaccination was not associated with a significant reduction in the overall dengue case risk in individuals without a documented history of dengue (VE: 12%; 95% CI: -21% to 36%). In this last stratum, vaccination was associated with reduced cases due to DENV-1 and DENV-4, but an excess of DENV-2 cases. Interpretation: Vaccination led to a significant reduction in reported dengue cases within the target population. The case-control design suggested that this reduction was primarily driven by the benefits observed in individuals with a documented history of dengue. In endemic regions with limited serological testing facilities, a previous history of dengue diagnosis recorded by epidemiological surveillance could be used to triage candidates for CYD-TDV vaccination.

RESUMO
PURPOSE: Fatigue is a phenomenon that may persist for years after completion of adjuvant therapy, and is one of the most frequent symptoms associated with breast cancer survivors. The purposes of this study were to investigate the occurrence of fatigue in disease-free breast cancer survivors after treatment, to identify variables associated with fatigue, and to evaluate the impact of fatigue on health-related quality of life. METHODS: A cross-sectional study was conducted on 202 consecutive women diagnosed with in-situ to Stage III breast cancer attending in outpatient facilities of two large hospitals, one year or more after diagnosis. They completed the Piper Fatigue Scale-Revised and the European Organization for Research and Treatment of Cancer QLQ-C30. Multiple logistic regression models were used to identify predictive factors associated with fatigue. EORTC QLQC-30 scores for fatigued survivors were compared to non-fatigued survivors. RESULTS: The prevalence of fatigue reported by the breast cancer survivors was 37.6%. Multiple logistic regression analysis revealed that predictive factors for fatigue included younger age (odds ratio [OR]=2.23, 95% confidence interval [CI]=1.11-4.45, p = 0.024); presence of pain (OR = 3.87, 95% CI = 1.88-7.98, p = 0.000); dyspnea (OR = 3.72, 95% CI = 1.46-9.50, p = 0.006); insomnia (OR = 2.40, 95% CI = 1.19-4.86, p = 0.015); and nausea and vomiting (OR = 12.25, 95% CI = 1.18-126.75, p = 0.036). Fatigued women had poorer health-related quality of life than non-fatigued women in all domains. CONCLUSION: Our results suggest that many disease-free breast cancer survivors after treatment experienced fatigue that compromises their health-related quality of life.

OBJECTIVE: Compare the characteristics of AIDS patients and treatment outcomes under three different antiretroviral treatment regimens advocated by the Ministry of Health of Brazil. METHODS: Retrospective cohorts of patients who had survived up to five years after diagnosis were constructed. The data were obtained from medical records, medication dispensing forms, and death certificates of patients in Curitiba, in the Brazilian state of Paraná. Six hundred patients were selected from the first six months following the adoption of each of the treatment regimens (1992, 1997, and 2002). RESULTS: The ratio of men to women fell from 6.5:1 in 1992 to 1.4:1 in 2002. There was a proportionate rise in the number of people over 50, which increased from 1.4% in 1992 to 9.9% in 2002. The case fatality rate dropped from 81.9% to 33.9% in the period in question. An analysis of those who survived at least five years from the date of diagnosis showed that the percentage of patients treated increased from 46.2% in 1992 to 94.0% in 1997, finishing at 91.7% in 2002. Multivariate analysis yielded a positive and statistically significant association between survival up to five years after an AIDS diagnosis and years of schooling, age group, year of diagnosis, type of antiretroviral therapy, and treatment adherence (all with P < 0.001). CONCLUSIONS: Continuous improvement of the antiretroviral therapy recommended by the Ministry of Health had a positive impact on survival. There was an association between case fatality and fewer years of schooling, membership in an older age group, a diagnosis obtained in 1992, the type of antiretroviral therapy, and suboptimal adherence to antiretroviral treatment regimens.

This study compared the incidence of hip fractures before and during the COVID-19 pandemic in Brazil, aged ≥ 60 years excluding all fractures related to any trauma. There was a significant reduction in the number of hip fractures and the length of hospital stay during the period of social isolation. PURPOSE: To compare the incidence of hip fractures before and during the COVID-19 pandemic in Brazil and in the main regions of the country in patients covered by the Brazilian public health care system (SUS). As far as we are aware, no studies have evaluated the impact of COVID-19 pandemic on hip fractures in Brazil. METHODS: Descriptive, cross-sectional study in individuals aged ≥ 60 years who presented with a hip fracture before and during the COVID-19 pandemic and received treatment covered by the SUS. The data were collected from the DATASUS electronic database. We calculated the incidence, mortality, lethality, duration of hospitalization, and average reimbursement associated with the treatment of the fractures. RESULTS: There was a significant reduction in the incidence of hip fractures among individuals aged ≥ 60 years in Brazil during the period of social isolation due to COVID-19. The observed incidence was 15.58/10,000 inhabitants between March and December 2020 and 16.07/10,000 inhabitants in the same period of 2019 (p < 0.005; main decline observed in the age groups > 70 years). The average length of hospital stay reduced from 8.35 days in 2019 to 7.33 days in 2020, following a similar pattern of reduction across all regions. The Southeast was the only region with a significant reduction in mortality during the pandemic (relative risk 0.90, 95% confidence interval 0.84-0.97, p < 0.005). CONCLUSION: During the COVID-19 pandemic in Brazil, the incidence rate of hip fractures and the associated duration of hospital stay decreased among patients aged ≥ 60 years.

After hospital discharge, workers are expected to return to work (RTW). However, the ability to return and any possible limitations after returning are unclear. Will they be able to RTW? Do they face limitations? This is a prospective cohort study with descriptive analysis aimed to investigate the RTW during 1 year following hospital discharge and to identify any limitations faced by the workers. Data collection occurred between February 2017 and July 2018 in an Internal Medicine Unit at a General Hospital. Convenience sampling was used, and participation was voluntary. Participants comprised 170 adults. Participants' RTW and limitations were followed for 1 year after discharge. During hospitalisation, 95.9% of participants planned to RTW. However, only 30% and 34.1% had returned after 1 month and 1 year respectively. Initially, 57.6% did not believe that they would present any limitation after discharge. However, 85.3% experienced restrictions after 1 month, and after 1 year this percentage rose to 88.2%. A correlation was found between young adults and RTW. The presence of limitations increased non-RTW risk. Therefore, it is recommended that the worker role should not be merely replaced by that of a patient, but it deserves attention of the latter in order to RTW activities. The work-return process must focus on understanding, treating and monitoring workers' limitations over time.

OBJECTIVE: The aim of this study was to evaluate the search for health information on the Internet and to determine the frequency and main means of spreading fake health news. METHODS: A descriptive cross-sectional study was conducted through the virtual distribution of questionnaires on social media platforms in 2019 by using the snowball technique. The questionnaire collected information regarding sociodemographics, means used to clarify doubts about health, implementation of information obtained through the Internet, receipt of fake news, and means of transmission of fake news. Quantitative variables are described as means and standard deviations, and categorical variables are described as frequencies and percentages. The chi-square and Fisher's exact tests were used. RESULTS: Out of 1,195 respondents, 53% had followed Internet guidance without consulting a health professional, especially young people and individuals with low education levels (p<0.05). The resources most used to answer questions about health were a physician (78%) and Google (51%), and searches using the latter were more predominant among younger age groups (p<0.05). A large part of the sample (89.4%) had received fake news, and the main means of receipt were Facebook and WhatsApp. CONCLUSIONS: The Internet was the second most commonly used means to search for health information. A significant portion of the population adopts actions based on this information. The frequency of broadcasting fake news through this digital medium is high.

OBJECTIVE: The aim of this cross-sectional study was to estimate the prevalence of XLH in Paraná, a state in southern Brazil, and report the clinical features and complications of the disease. METHODS: We invited all endocrinologists (n = 205), nephrologists (n = 221), orthopedic surgeons (n = 1020), and pediatricians (n = 1000) in Paraná to fill out an electronic survey with information on patients with X-linked hypophosphatemia (XLH), and searched the records of the state's health department for all calcitriol prescriptions in 2018. RESULTS: In all, 244 (10%) specialists responded to the email, of whom 18 (7.4%) reported to be taking care of patients with XLH and answered the online survey. A total of 57 patients with XLH were identified (prevalence 5 per million inhabitants). The median age at diagnosis was 22 years, and 42.2% were children and adolescents. Fifteen patients had genetic testing showing a PHEX mutation. Overall, 91.2% had bone deformities, 30.8% had a history of fragility fractures, and 22.4% had renal complications. CONCLUSION: This study demonstrated a prevalence of XLH of 5 cases per million inhabitants in the state of Paraná, a rate lower than the one reported in other countries. Manifestations of renal calcification and bone fragility were frequent among the patients. This is the first epidemiological study evaluating the prevalence and clinical presentation of XLH in Latin America.

The success of vaccination programs depends on the level of acceptance of the vaccine to achieve high vaccine coverage rates (VCR). Vaccine hesitancy is a challenge, especially concerning new vaccines. Dengue vaccine, Dengvaxia®, was licensed in Brazil in 2015 and implemented, in a pioneering publicly-funded initiative in the state of Paraná, between 2016 and 2018. The vaccination program took place in five phases in the 30 municipalities most affected by dengue in the state, targeting individuals from nine to 44 years-old in two cities and from 15 to 27 years-old in the other 28 municipalities, totaling a target population of 500,000 individuals. A cross-sectional descriptive study was carried out to assess VCR and adherence to the dengue vaccine in this program. VCR, dropout ratio (DR), and compliance with the vaccination schedule (CVS) were analyzed by sex, age group, and municipality size. A total of 302,603 individuals (60.5%) received ≥ 1 dose, 44.2% received ≥ 2 doses, and 28.6% 3 doses. The DR was 52.8%. Among individuals who started vaccination, 40.6% achieved CVS. The highest VCR, highest CVS, and lowest DR occurred in the age group from 9 to 14 years old and from 28 to 44 years old and in smaller municipalities. A greater proportion of men started vaccination (male 64.0%; female 57.1%) however, the DR was higher in men (male 55.4%; female 49.9%), and a higher percentage of women completed the vaccination schedule according to the recommendations (CVS male 37.8%; female 43.6%). Differences were noted in the CVS according to the initial phase of the program (first phase 50.8%; second phase 18.8%). The heterogeneity in vaccine uptake and compliance according to sex, age, and municipality size suggests the need for differentiated strategies to address challenges with new and multiple-dose vaccines.

Bisphenol A (BPA) is a substance extensively used in daily life, mainly in plastic materials. This study assessed the exposure of university students to endocrine disruptor BPA, their knowledge about this substance and the damage it causes to human health. This is a cross-sectional descriptive study carried out with 500 students from a University in Curitiba. The sample was selected proportionally to the three major areas of knowledge, and the courses interviewed were drawn at random. Students were asked to fill out an objective questionnaire consisting of three parts: socioeconomic, assessment of exposure and knowledge tests. Of the respondents, 91.3% consume food stored in plastic packaging, 90.06% use drinks in this type of container and 84.8% consume canned food/drinks. However, only 19.8% have heard of BPA and 97.2% do not know about the relationship between exposure to BPA and endocrine changes. A high rate of exposure to BPA and a low level of knowledge on the subject was detected. This disproportion highlights the need for more in-depth research on the topic among the Brazilian population, in addition to broadening dissemination of information measures on the issue.
O Bisfenol-A (BFA) é uma substância amplamente empregada no cotidiano, principalmente nos materiais plásticos. Este estudo avaliou a exposição de universitários ao disruptor endócrino BFA, o conhecimento dos mesmos acerca dessa substância e dos seus danos à saúde humana. Trata-se de um estudo transversal descritivo realizado com 500 estudantes de uma Universidade de Curitiba. A amostra foi selecionada de forma proporcional as três grandes áreas do conhecimento, sendo que os cursos entrevistados foram sorteados. Aos estudantes aplicou-se um questionário objetivo composto por três partes: socioeconômica, avaliação da exposição e testes de conhecimento. Dos respondentes, 91,3% consomem alimentos armazenados em embalagens plásticas, 90,06% utilizam bebidas nesse tipo de recipiente e 84,8% consomem bebidas/alimentos enlatados. Entretanto, apenas 19,8% já ouviram falar em BFA e 97,2% não sabem sobre a relação entre a exposição ao BFA e alterações endócrinas. Observou-se uma alta taxa de exposição ao BFA e um baixo nível de conhecimento sobre o assunto. Essa desproporção evidencia a necessidade de pesquisas mais aprofundadas sobre o tema na população brasileira, além da ampliação de medidas informativas.

PURPOSE: To evaluate the association of dental caries with behavioural, socioeconomic and cultural factors; and Streptococcus mutans (SM) levels in the saliva and oral hygiene index of children aged 4 and 6 years old placed in an oral health programme. MATERIALS AND METHODS: This study was an analytic cross-sectional oral health survey conducted over a 9-month period. A total of 466 children aged 4 and 6 years old were included for evaluation of SM levels in saliva, simplified oral hygiene index and dental caries activity. RESULTS: High SM levels were associated with dmft index, toothbrushing without parental assistance, deficient oral hygiene and ingestion of sweet foods. Deficient oral hygiene was found in children aged 4 years old and with three or more siblings. Dental caries was associated with low family income, deficient oral hygiene, sucrose ingestion by children younger than three years old, bottle-feeding habit and low parental compliance. CONCLUSIONS: High SM levels in saliva, deficient oral hygiene and high frequency of sucrose ingestion had association with dental caries in children. Cultural, socioeconomic and behaviour factors indirectly influenced the onset of dental caries.

UNLABELLED: Background Associations between aplastic anemia and numerous drugs, pesticides and chemicals have been reported. However, at least 50% of the etiology of aplastic anemia remains unexplained. DESIGN AND METHODS: This was a case-control, multicenter, multinational study, designed to identify risk factors for agranulocytosis and aplastic anemia. The cases were patients with diagnosis of aplastic anemia confirmed through biopsy or bone marrow aspiration, selected through an active search of clinical laboratories, hematology clinics and medical records. The controls did not have either aplastic anemia or chronic diseases. A total of 224 patients with aplastic anemia were included in the study, each case was paired with four controls, according to sex, age group, and hospital where the case was first seen. Information was collected on demographic data, medical history, laboratory tests, medications, and other potential risk factors prior to diagnosis. RESULTS: The incidence of aplastic anemia was 1.6 cases per million per year. Higher rates of benzene exposure (>/=30 exposures per year) were associated with a greater risk of aplastic anemia (odds ratio, OR: 4.2; 95% confidence interval, CI: 1.82-9.82). Individuals exposed to chloramphenicol in the previous year had an adjusted OR for aplastic anemia of 8.7 (CI: 0.87-87.93) and those exposed to azithromycin had an adjusted OR of 11.02 (CI 1.14-108.02). Conclusions The incidence of aplastic anemia in Latin America countries is low. Although the research study centers had a high coverage of health services, the underreporting of cases of aplastic anemia in selected regions can be discussed. Frequent exposure to benzene-based products increases the risk for aplastic anemia. Few associations with specific drugs were found, and it is likely that some of these were due to chance alone.

INTRODUCTION: Background and aims: home enteral nutrition (HEN) is an established treatment for clinically stable patients. The objective of this study was to determine the frequency and the situation of patients in HEN, in the capital city in the south of Brazil. Methods: in this retrospective study, we recorded all new cases of HEN in adults in Curitiba, Brazil, from January 2006 to December 2015. Data were collected by a dietitian from medical records of patients attending public health settings. The following data were analyzed: clinical diagnosis, diet prescribed during hospitalization and at discharge, and feeding access types. Kaplan-Meier and Cox regression analyses were used to calculate survival. Results: a total of 1,231 patients were included. There was a 425% increase in the frequency of HEN over the years studied. The mean age was 66.7 years, and 54.4% were men. Neurological diseases were the most prevalent (46.4%), followed by cancer (33.6%). Eight hundred and one patients (65.1%) died during this period. Mean HEN duration was 180 days (95% CI 163.6-193.4), with a significant difference between neurological diseases (median: 180 days) and cancer (median: 210 days) (p < 0.05). Neurological disease was an independent risk factor for mortality in patients on HEN (HR: 1.17; CI: 1.08-1.27). Conclusions: the study shows an increase in HEN. Neurological diseases prevailed and presented a risk of mortality, and more than half of the patients with NED died in this period.
INTRODUCCIÓN: Introducción y objetivos: la nutrición enteral domiciliaria (NED) es un tratamiento establecido para pacientes clínicamente estables. El objetivo de este estudio fue determinar la frecuencia y la situación de los pacientes con NED en la capital del sur de Brasil. Métodos: en este estudio retrospectivo se registraron todos los nuevos casos de NED en adultos en Curitiba, Brasil, de enero de 2006 a diciembre de 2015. Los datos fueron recolectados por un nutricionista de historiales clínicos de pacientes que frecuentan establecimientos de salud pública. Se analizaron los siguientes datos: diagnóstico clínico, dieta prescrita durante la estancia hospitalaria y en el momento del alta y acceso alimenticio. Se utilizaron los análisis de Kaplan-Meier y regresión de Cox para calcular la supervivencia. Resultados: fueron incluidos 1.231 pacientes. Hubo un aumento del 425% en la frecuencia de NED a lo largo de los años estudiados. La edad media fue de 66,7 años y el 54,4% eran hombres. Las enfermedades neurológicas fueron las más prevalentes (46,4%), seguidas de las neoplasias (33,6%). Durante este periodo murieron 801 pacientes (65,1%). La duración media de la NED fue de 180 días (IC 95%, 163,6-193,4), con una diferencia significativa entre enfermedades neurológicas (mediana: 180 días) y cáncer (mediana: 210 días) (p < 0,05). La enfermedad neurológica fue un factor de riesgo independiente para la mortalidad en pacientes en NED (HR: 1,17; IC: 1,08-1,27). Conclusiones: el estudio muestra un aumento en la NED. Las enfermedades neurológicas prevalecieron y presentaron riesgo de mortalidad y más de la mitad de los pacientes murieron durante la NED.

PURPOSE: LATIN is a multinational case-control study designed to identify risk factors for agranulocytosis and to estimate the incidence rate of the disease in some Latin American countries. METHODS: Each study site in Brazil, Argentina and Mexico conducted an active search of agranulocytosis patients in hematology clinics and looked for possible associations with drug use. RESULTS: The overall incidence rate was 0.38 cases per 1 million inhabitant-years. Agranulocytosis patients more often took medications already associated with agranulocytosis than controls (p = 0.01), mainly methimazole (OR 44.2, 95% CI 6.8 to infinity). The population attributable risk percentage (etiologic fraction) was 56%. The use of nutrient supplements was more frequent among patients than controls (p = 0.03). CONCLUSIONS: Agranulocytosis seems to be very rare in Latin America. The lower than expected number of cases identified during the study period precluded estimation of the risk associated to individual drugs, with the exception of methimazol. However, this is the longest series of agranulocytosis cases ever gathered in Latin America, and information on drug exposures was collected prospectively. The conclusion is that drug-induced agranulocytosis does not seem to be a major public health problem in the study regions.

Leprosy is a disease, which is accompanied by cellular immunity defects, which may increase the susceptibility of patients in developing co-infections. The association of leprosy with hepatitis C virus (HCV) infection, human immunodeficiency virus types 1 and 2 (HIV 1+2) infection and human T-lymphotropic virus types I and II (HTLV I+II) infection have previously been described in different populations. In this study, the prevalence of these infections was determined in 199 Southern Brazilian leprosy patients and in 681 matched controls. Antibodies to HCV were positive in 3.52% of the patients (7/199) and in 0.15% of the controls (1/681; odds ratio (OR)=24.79; 95% CI=3.03-202.74; p=0.0002). An increased risk of HCV infection was observed in institutionalized patients (OR=14.95; 95% CI=1.76-127.03; p=0.004) and in the lepromatous form of the disease (OR=7.67; 95% CI=0.43-136.62; p=ns). Anti-HIV 1+2 antibodies were positive in only one out-patient (1/199; 0.50%) and in none of the controls (0/681; OR=3.43; 95% CI=0.21-55.16; p>0.05). No leprosy patient was positive for anti-HTLV I+II antibodies. These results demonstrate an increased prevalence of HCV infection in leprosy patients from South Brazil and that both institutionalization and lepromatous form of the disease confer higher risk to HCV infection. These data emphasizes the importance of monitoring hepatitis C and leprosy interactions and the need of special care to institutionalized and lepromatous patients in preventing HCV co-infection.

BACKGROUND: - The fourth most frequent tumor in the world, colorectal cancer is commonly diagnosed at an advanced stage. OBJECTIVE: - To analyze factors that interfere in the diagnosis of colorectal cancer in users of the Public Health System treated at an universitary hospital in Curitiba, Paraná State, Brazil. METHODS: - Cross-sectional, quantitative and descriptive study with 120 patients treated at the institution between 2012 and 2013. Data collection, carried out by means of medical record appointments and patients' interviews, addressed sociodemographic variables; clinical profile; timespan between symptoms, examination, diagnosis, treatment onset and difficulties encountered. Statistical analyses were performed by means of Stata 8.0. RESULTS: - Abdominal pain was the most frequent complaint and rectal bleeding presented the highest chance of advanced colorectal cancer diagnosis. From 52.5% of patients with late diagnosis of colorectal cancer, 81% reported difficulties in the health system. CONCLUSION: - Results suggest that late diagnosis is due to symptom absence in the early stage of the disease, patients' lack of perception about the severity of the symptoms, need of better of health teams to search early diagnosis. Educational interventions are deemed necessary to the population and health teams, besides actions prioritizing the access to diagnostic testing for serious illnesses.
