ABSTRACT Objective: To describe the first known case of human Bertiellosis in Paraná (Brazil). Case description: A 6-year-old male residing in the Brazilian state of Paraná was suffering from intermittent nonspecific abdominal pain and abdominal distension, associated with expulsion of live tapeworms in his feces for 7 months. He had a history of interaction with monkeys on an island. His first feces analysis was inconclusive, with an initial hypothesis of an atypical Taenia. However, after additional research, the parasitologist identified pregnant proglottids of Bertiella sp. The patient was initially treated with an unknown dosage of albendazole and nitazoxanide, as it was believed he had been infected with Taenia sp. Since the symptoms persisted, praziquantel 10 mg/kg was prescribed without further proglottids elimination. Comments: Human Bertiellosis is a rare zoonosis, with less than one hundred cases reported. However, it is a cause of chronic abdominal pain and should be kept as a differential diagnosis, especially in cases reporting recurrent tapeworm expulsion in feces and refractory treatment with albendazole.

RESUMO Objetivo: Descrever o primeiro caso conhecido de bertielose humana no Paraná, Brasil. Descrição do caso: Criança de seis anos do sexo masculino, residente no Paraná, Brasil, apresentava dor abdominal inespecífica intermitente e distensão abdominal, associadas à expulsão de helmintos vivos em suas fezes havia sete meses. Tinha um histórico de interação com macacos em uma ilha. Sua primeira análise de fezes foi inconclusiva, com hipótese inicial de uma Taenia atípica. No entanto, após pesquisas adicionais, o parasitologista identificou proglótides gravídicas de Bertiella sp. O paciente foi inicialmente tratado com uma dosagem desconhecida de albendazol e nitazoxanida, pois se acreditava que havia sido infectado por Taenia sp. Diante da persistência dos sintomas, foi prescrito praziquantel 10 mg/kg, sem mais eliminação de proglótides. Comentários: A bertielose humana é uma zoonose rara, com menos de cem casos relatados. No entanto, é uma causa de dor abdominal crônica e deve ser mantida como diagnóstico diferencial, principalmente nos casos que relatam expulsão recorrente de helmintos nas fezes e que são refratários ao tratamento com albendazol.

Abstract Objective To analyze the effectiveness, safety, outcomes, and associated factors of tuberculosis preventive treatment (TPT) in children and adolescents in Paraná, southern Brazil. Method This was an observational cohort study with a retrospective collection of secondary data from the TPT information systems of the state of Paraná from 2009 to 2016, and tuberculosis in Brazil from 2009 to 2018. Results In total, 1,397 people were included. In 95.4% of the individuals, the indication for TPT was a history of patient-index contact with pulmonary tuberculosis. Isoniazid was used in 99.9% of the cases with TPT, and 87.7% completed the treatment. The TPT protection was 98.7%. Among the 18 people who had TB, 14 (77.8%) became ill after the second year of treatment, and four (22.2%) in the first two years (p < 0.001). Adverse events were reported in 3.3% of cases, most of them were gastrointestinal and medication was discontinued in only 2 (0.1%) patients. No risk factors associated with the illness were observed. Conclusions The authors observed a low rate of illness in pragmatics routine conditions in TPT for children and adolescents, especially within the first two years after the end of treatment, with good tolerability and a good percentage of adherence to the treatment. TPT should be encouraged to achieve the goals of the End TB Strategy of the World Health Organization as an essential strategy to reduce the incidence rate of the disease, but studies with new schemes must continue to be carried out in real-life scenarios.

ABSTRACT This study investigated the potential use of the String Test (ST) for the diagnosis of pulmonary tuberculosis (PTB) in children and adolescents. This is a case series of patients aged 4-15 years presenting with clinically presumed PTB and submitted to ST in three pediatric TB referral centers in Brazil, between November 2017 and July 2020. The ST was performed in the morning, after 4-12 h of fasting, followed by ingestion of the capsule by the patient, which was attached to the patient’s malar region. The material was collected for simultaneous smear microscopy (acid-fast bacilli - AFB), culture and the molecular investigation by the GeneXpert MTB/RIF®. Thirty-three patients with presumed PTB were included and ST was performed in 26 (78.8%) of them and 7 (21.2%) patients could not swallow the cord. The diagnosis of PTB was established in 11 (42.3%) of the 26 patients who underwent the ST. The diagnosis of PTB was confirmed (by culture or GeneXpert MTB/RIF®) in 5 patients, 4 of whom were also positive by the ST. Two of them showed positivity by the GeneXpert MTB/RIF® only in the ST sample. Two other patients had a positive ST following the induced sputum test (AFB, GeneXpert MTB/RIF®, and positive culture in both specimens). Thus, ST was positive in 36.4% of the patients in whom PTB was diagnosed. ST could be a useful test for diagnosing PTB in children and adolescents.

Resumo Objetivo Descrever a situação epidemiológica da tuberculose nos menores de 19 anos no Brasil e revisar as últimas publicações sobre risco de adoecimento, diagnóstico, tratamento e prevenção. Fonte dos dados Banco de notificação Brasil (2018), estimativas da Organização Mundial da Saúde e artigos do PubMed selecionados pelo descritor Tuberculosis, delimitaram-se tipo de estudo, período, idade e língua. Síntese dos dados Em 2018, no Brasil, 9,4% das notificações foram nos menores de 19 anos. Predominou a forma pulmonar em 80,1% dos casos. A taxa de cura foi de 76,8%, letalidade 0,8% e abandono 10,4%. A prevalência de tuberculose drogarresistente (2011 a 2016) foi 0,5%. Encontrou-se que o risco de adoecimento pode chegar até 56%, nos menores de cinco anos, influenciado por coinfecções com helmintos, malária, infecções virais crônicas, vacinas de vírus vivos atenuados e hipovitaminose D. A exposição ao doente bacilífero por períodos menores de 30 minutos é suficiente para o desenvolvimento de infecção e/ou doença. No Brasil, recomenda-se a pesquisa microbiológica, porém mantem-se o uso do Sistema de Pontuação, modificado em 2019. Estudos sobre detecção da infecção respaldaram o uso da prova tuberculínica. No tratamento, o grande avanço foi a introdução das formulações dispersíveis, adequação das doses preconizadas e esquemas encurtados para infecção latente. Vários estudos de vacinas (fases de 1 a 3) estão em andamento, mas ainda sem substituto licenciado para a BCG. Conclusões Observaram-se progressos no tratamento, porém ainda há grandes desafios para melhorar o diagnóstico, monitoramento e desfecho dos casos em busca da eliminação da tuberculose.

Abstract Objective To describe the epidemiological situation of tuberculosis in children under 19 years of age in Brazil and to review the latest publications on disease risk, diagnosis, treatment, and prevention. Source of data Notifiable Diseases Information System (2018), World Health Organization estimates, and PubMed articles selected using the descriptor “Tuberculosis,” delimited by type of study, period, age, and language. Synthesis of data In 2018, in Brazil, 9.4% of notifications were in children under 19 years. The pulmonary form predominated in 80.1% of the cases. The cure rate was 76.8%, lethality was 0.8%, and abandonment was 10.4%. The prevalence of drug-resistant tuberculosis (2011-2016) was 0.5%. It has been found that the risk of disease can reach up to 56% in children under 5 years, influenced by helminth co-infections, malaria, chronic viral infections, live attenuated virus vaccines, and hypovitaminosis D. Exposure to a bacilliferous patient for periods shorter than 30 minutes is sufficient for the development of infection and/or disease. In Brazil, microbiological screening is recommended, but the use of the scoring system, modified in 2019, has been maintained. Studies on infection detection have supported the use of the tuberculin skin test. In the treatment, the great advance was the introduction of dispersible formulations, adjustment of the recommended doses, and shortened regimens for latent infection. Several vaccine studies (stages 1-3) are ongoing, but no BCG-licensed substitute has been implemented yet. Conclusions There has been progress in treatment, but major challenges need to be overcome to improve diagnosis, monitoring, and outcome of cases, aiming to eliminate tuberculosis.

ABSTRACT The aim of this study was to evaluate the concordance between two versions of the scoring system (2011 and 2019), recommended by the Brazilian Ministry of Health, for the diagnosis of pulmonary tuberculosis (PTB) in children and adolescents. A retrospective descriptive study was performed to assess the medical records of children and adolescents with PTB, in TB units from Brazilian cities located in Rio de Janeiro, Minas Gerais, and Parana States, from January 1 st , 2004, to December 1 st , 2018. Patients aged 0 to 18 years old with a diagnosis of PTB were included. The comparison between the two scoring systems showed a moderate concordance according to the κ coefficient value = 0.625. Fourteen patients showed a reduction in the TB score, going from 30 points in the 2011, to 25 points or less in the 2019 one. Seventy one percent of these 14 patients had radiological changes suggestive of PTB and 86% had tuberculin skin tests greater than 10 mm. The study concluded that a moderate agreement was observed between the 2011 and 2019 scoring systems, with an increase in the number of patients scoring 25 points or less in 2019, which can eventually hinder the diagnosis of PTB.

RESUMO Objetivo: Identificar a forma mais efetiva de contato, como possibilidade de intervenção, para diminuir o absenteísmo em consultas de crianças com suspeita ou com tuberculose pulmonar. Métodos: Ensaio clínico randomizado com coleta de dados prospectiva, entre março de 2017 e fevereiro de 2018. Os pacientes foram aleatorizados em três grupos para relembrar a consulta: contato telefônico; mensagens curtas (SMS) ou WhatsApp; e nenhuma intervenção. Amostra de conveniência, com nível de significância de 5%. Resultados: Incluídas 78 crianças, mediana de idade quatro anos (zero a 14); 59,0% em tratamento para infecção latente e 6,4% com tuberculose ativa; 74,4% moravam em Curitiba, Paraná; 62,8% residiam com ambos os pais; 38,5% dos pais possuíam emprego formal e 47,4% das mães eram do lar; 50,8% dos pais e 55,7% das mães possuíam mais de nove anos de estudo; em 78,2% das famílias a renda per capita foi de até 0,5 salário mínimo; 27,3% estavam inscritas em programas sociais; e 28,2% residiam em casa cedida. Foram 238 intervenções: 85 (35,7%) por contato telefônico, 78 (32,8%) por mensagem de texto (WhatsApp 97,2%) e 75 (31,5%) sem nenhum contato adicional. Nas características sociodemográficas e culturais estudadas não houve diferença estatística. O absenteísmo foi de 24,0% e o abandono, de 16,7%. Lembrar o responsável previamente à consulta, independente da intervenção (p=0,021) e especificamente por mensagem por WhatsApp (p=0,032) foi associado ao não absenteísmo, porém não associado ao abandono. Conclusões: O uso de novas ferramentas, como o aplicativo WhatsApp, pode reduzir o absenteísmo, diminuir a possibilidade de abandono no seguimento e melhorar o desfecho do tratamento de crianças com tuberculose, seja a infecção ou a doença.

ABSTRACT Objective: To identify the most effective form of contact, as a possible intervention to reduce absenteeism in consultations of children with suspected or confirmed pulmonary tuberculosis. Methods: A randomized clinical trial was conducted with prospective data collection, between March 2017 and February 2018. Patients were randomized into three groups to be reminded about the appointment: telephone contact, SMS or WhatsApp, or no intervention. A convenience sample was obtained, with a significance level of 5%. Results: 78 children were included, with a median age of four years old (zero to 14); 59.0% of them were in treatment for a latent infection and 6.4% had active tuberculosis. Among the 78 children, 74.4% lived in Curitiba (Sourhern Brazil); 62.8% lived with both parents; 38.5% of the parents had formal employment and 47.4% of the mothers were housewives; 50.8% of the fathers and 55.7% of the mothers had more than nine years of schooling. In 78.2% of the families, per capita income was up to 0.5 minimum wages; 27.3% were enrolled in social programs; 28.2% lived in homes provided by the government. There was a total of 238 interventions made: 85 (35.7%) by telephone contact, 78 (32.8%) by text message (WhatsApp was 97.2% of these) and 75 (31.5%) had no further contact. There was no statistical difference among the sociodemographic and cultural characteristics studied. The absenteeism rate was 24.0% and the abandonment rate was 16.7%. Giving a reminder to the patient’s guardian prior to the consultation, regardless of the intervention (p=0.021) and specifically by WhatsApp message (p=0.032) was associated with no absenteeism, though it was not associated with abandonment of the treatment. Conclusions: Using new tools, such as WhatsApp, to remind guardians of appointments reduces absenteeism. Consequently, it may lead to a reduction in abandoning treatment and it may improvetreatment outcome of children with a tuberculosis infection or disease.

RESUMO: Introdução: Todo recém-nascido exposto à sífilis na gestação deve ter acompanhamento ambulatorial. A interrupção do seguimento põe em risco todos aqueles que não recebem tratamento ao nascer. Objetivo: Descrever as características clínicas e epidemiológicas dos recém-nascidos expostos à sífilis, assim como gestacionais e sociodemográficas de suas mães e investigar os fatores associados com a descontinuidade do seguimento. Métodos: Trata-se de um estudo observacional, descritivo, analítico e retrospectivo dos prontuários de 254 crianças expostas à sífilis, atendidas no Ambulatório de Infecções Congênitas do Hospital de Clínicas da Universidade Federal do Paraná, entre 2000 e 2010. Os recém-nascidos foram classificados por referência ao seu acompanhamento ou não. Os dados foram ajustados a um modelo de regressão logística binária, no sentido de identificar os fatores associados à descontinuidade do tratamento. Resultados: As características estatisticamente associadas à interrupção do seguimento na análise multivariada foram: mães com idade acima de 30 anos, paridade de três ou mais filhos e a ausência de coinfecções pelo HIV e/ou hepatites virais. Conclusão: Tais achados demonstram a necessidade de identificar essas famílias e estabelecer estratégias que incentivem a formação de vínculos. Recomenda-se que os critérios de tratamento dos recém-nascidos tenham maior rigor, visto que a maior parte deles não faz o seguimento adequado.

ABSTRACT: Introduction: All newborns exposed to syphilis in pregnancy must have outpatient follow-up. The interruption of this follow-up especially threatens those children who were not treated at birth. Objective: To describe the clinical, epidemiological, and sociodemographic characteristics of pregnant women with syphilis and their newborns, and to investigate the factors associated with the discontinuation of the follow-up. Methods: This is an observational, descriptive, analytical, and retrospective study of medical records of 254 children exposed to syphilis, who were assisted at the Congenital Infectious Clinic of the university hospital of the Universidade Federal do Paraná, between 2000 and 2010. The newborns were classified by reference according to their follow-up. Data were analyzed by means of the binary logistic regression model in order to identify the factors associated to drop out. Results: The factors associated to the interruption of the follow-up were maternal age over 30 years, mothers with 3 or more children, and the absence of cross-infections by HIV and/or viral hepatitis. Conclusion: Such findings demonstrate the need to identify these families and implement strategies to promote the establishment of bonds. A greater rigor to indicate the treatment of the disease at birth is recommended, as most of them do not properly follow up.

Abstract Setting Patients HIV+ attending in a reference clinic, Southern Brazil. Objective To compare the interferon-gamma-release assay (IGRA – QuantiFERON® TB Gold In-Tube) with the tuberculin skin test (TST – PPD-Rt 23) for latent tuberculosis infection (LTBI) in patients with HIV. Design Cohort study. Patients were simultaneously submitted to the TST and blood collection for the IGRA. Results A total of 140 subjects were included. Nine (6.4%) were IGRA+/TST+, 12 (8.6%) were IGRA+/TST−, 4 (3%) were IGRA−/TST+, and 115 (82%) IGRA−/TST−. There was poor agreement between tests (kappa = 0.2), and no correlation between these results and CD4+ T lymphocyte counts. During follow-up, one patient with negative results on both tests died from sepsis, and another with discordant results (IGRA+/TST−) exhibited TST seroconversion. Compared to the TST, IGRA showed a sensitivity and specificity of 69% and 90%, respectively. The IGRA detected 8% more positive results than the TST. All patients were followed up for 2 years. Conclusion The higher accuracy of the IGRA would result in LTBI treatments being administered to patients who would have otherwise been overlooked, decreasing the number of active tuberculosis cases. The long-term survival of HIV carriers requires further evaluation.

OBJETIVO: Analisar fatores de risco para recidiva de câncer colorretal após tratamento cirúrgico. MÉTODO: Avaliou-se 65 pacientes com adenocarcinoma colorretal, estadio I e II (TNM), submetidos à cirurgia com intenção curativa, acompanhados por cinco anos após a operação. Analisou-se presença de tratamento adjuvante/neoadjuvante, grau de diferenciação do tumor, infiltração vascular linfática e venosa, profundidade de invasão tumoral e estadiamento da doença, estabelecendo-se para cada um o risco relativo de recidiva aos dois anos, após dois anos e aos cinco anos de seguimento. RESULTADOS: Recidiva global em cinco anos foi 21,4% (14/65), com idêntica incidência (10,7%) nos períodos separados. Somente as infiltrações vasculares linfáticas e venosas apresentaram associação estatisticamente significativa com a recidiva nos períodos de análise. Encontrou-se risco relativo (RR) estatisticamente significativo após dois anos relacionados à presença de infiltração linfática [RR = 6 (1,3 - 28,5) p = 0,01] e infiltração venosa [RR = 9,5 (2,6 - 34,9) p < 0,001]. Após cinco anos, apenas a infiltração venosa manteve a significância estatística, com risco relativo elevado para ocorrência de recidiva [RR = 3,9 (1,8 - 8,8) p < 0.001]. Na análise multivariada apenas a presença de infiltração vascular venosa com 81,5% de acerto foi associada à recidiva (p < 0.001). CONCLUSÃO: Nesta série, os únicos fatores associados com risco de recidiva do câncer colorretal foram a presença de infiltração vascular linfática e venosa.

OBJECTIVE: Evaluate risk factors for colorectal cancer recurrence after surgical treatment. METHODS: Sixty-five patients with colorectal adenocarcinoma, stage I and II (TNM), undergoing curative-intent surgery and followed for five years were studied. Presence of adjuvant/neoadjuvant therapy, tumor differentiation degree, lymphatic and venous vascular infiltration, depth of tumor invasion, and disease staging was analyzed, using recurrence relative risk ratios for each parameter calculated at two years, after two years and five years of follow up. RESULTS: At five years, recurrence was 21.4% (14/65), with equal incidence (10.7%) for the separated periods. Only lymphatic and venous vascular infiltration showed statistically significant association with recurrence during times analyzed. Relative risk (RR) of recurrence was significantly related to the presence of lymphatic infiltration [RR = 6 (1.3 - 28.5) p = 0.01] and venous infiltration [RR = 9.5 (2.6 - 34.9) p < 0.001] after two years of follow-up. At five years follow-up, only venous infiltration remained with significant relative risk for recurrence [RR = 3.9 (1.8 - 8.8) p < 0.001]. In a multivariate analysis, only venous vascular infiltration was associated with recurrence [accuracy 81.5% (p < 0.001)]. CONCLUSION: In this series, the factors associated with risk of colorectal cancer recurrence were the presence of lymphatic and venous vascular infiltration.

Changes in immune system functions are one of the most important consequences of human immunodeficiency virus (HIV) infection. Studies have reported a higher prevalence of disease mediated by immunological hypersensitivity mechanisms in HIV-positive patients. This study aims to observe how immunological changes in HIV-infected children interfere in atopy determinants. Fifty-seven HIV-positive children were studied between June 2004-August 2005 to evaluate the possible modifications in atopy diagnosis from prick test environmental allergen reactivity. Patients were subjected to two evaluations: on both occasions, atopic and non-atopic groups were correlated with immunological (CD4+ and CD8+ lymphocyte concentrations and serum levels of IgA, IgM, IgG and IgE) and viral parameters (HIV viral load). The percent atopy was 20.05 in the first and 29.82 in the second evaluation and atopy was diagnosed in patients without immunosuppression or with moderate immunosuppression. Six patients changed from a negative to a positive atopy profile. One patient with a decreased CD4+ T lymphocyte concentration failed to demonstrate prick test positivity between evaluations. Multivariate analysis showed that the variables associated with atopy diagnosis included a personal history of allergic diseases as well as elevated IgE for age and elevated IgE levels. Atopy development in HIV-infected children seems to be modulated by genetic and environmental factors as well as immunological condition.

The aim of this study is to evaluate the clinical and laboratorial aspects, as well as the etiological profile and the evolution characteristics, of the diverse types of severe meningitis treated at a Pediatric Clinic of a public university hospital. From a descriptive and retrospective study, 312 children at the Pediatric Clinic of the Hospital de Clínicas of the Federal University of Paraná were evaluated between January 2003 and January 2007. All of them had a probable diagnosis of meningitis based on clinical signs, and on the cytological and biochemical alterations in the cerebrospinal fluid routine examination. Viral meningitis (VM) was present in 140 children (45%), 58 had bacterial meningitis (BM - 19%) and etiology was undetermined in 114 (36%). In MB, Neisseria meningitidis was the most frequent etiological agent (25 cases). Predominant clinical symptoms were fever, sickness and headache. The cerebrospinal fluid test showed a high number of polymorphonuclear leukocytes, high protein and low glucose level in MB; mononuclear cells were predominant in VM. Neurological complications were more frequent in BM, and convulsion the most common symptom (6/58 patients). Death happened to one case in VM and 3 in BM. Our conclusions were that the classical triad (headache, vomiting and fever) was the most common clinical manifestation, the cytological and biochemical abnormalities were typical, helping in the differentiation of MB from VM, although a good number of cases ended up with no etiological definition and, finally, immediate neurological complications and death were rare.

El objetivo de este trabajo fue evaluar los aspectos clínicos, análisis de laboratorio, el perfil etiológico y las características evolutivas de los distintos tipos de meningitis aguda atendidos en un Servicio de Pediatría de un Hospital Público Universitario. Fueron evaluados a partir de un estudio descriptivo y retrospectivo de niños atendidos en el Servicio de Pediatría del Hospital de Clínicas de la Universidad Federal del Paraná, durante el periodo entre enero 2003 a enero 2007, con el diagnóstico probable de meningitis basado en manifestaciones clínicas y en alteraciones citológicas y bioquímicas del LCR. Se diagnosticó meningitis viral (MV) en 140 niños (45%), meningitis bacteriana (MB) en 58 (19%) y en 114 la etiología fue indeterminada (36%). Entre las MB el agente etiológico más frecuente fue Neisseria meningitidis (25 casos). Lo datos clínicos predominantes fueron fiebre, vómitos y cefalea. En el LCR de la MB hubo predominio de polimorfonucleares, proteína elevada y glucosa baja. En la MV predominaron los mononucleares. Las complicaciones neurológicas fueron más frecuentes en la MB, siendo la convulsión el hallazgo más común (6/58 pacientes). El óbito ocurrió en un caso en la MV y tres en la MB. Se llegó a la conclusión de que la clásica tríada fue la manifestación clínica más común, las anormalidades citológicas y bioquímicas fueron típicas auxiliando en la diferenciación entre las MB y MV, aunque un gran número de casos haya quedado sin definición etiológica; las complicaciones neurológicas inmediatas y los óbitos han sido pocos frecuentes en esta muestra.

OBJETIVO: Comparar o uso das soluções orais de manitol a 10% e de bifosfato de sódio no preparo mecânico do cólon quanto a qualidade da limpeza, a tolerabilidade e as alterações hidroeletrolíticas e da osmolaridade plasmática. MÉTODO: Foram analisados 60 pacientes de modo randomizado, duplo-cego e prospectivo, com indicação de colonoscopia. A qualidade da limpeza intestinal foi analisada pelo examinador através da classificação de Beck. A tolerabilidade à ingestão baseou-se na pesquisa do gosto, presença ou não de desconforto, aparecimento de efeitos adversos e a quantidade da solução ingerida. Foram dosados o sódio, potássio, cálcio, magnésio, fósforo, uréia, creatinina, glicose, hematócrito, hemoglobina e calculado a osmolaridade plasmática, antes e após a ingestão da solução oral de preparo inestinal. RESULTADOS: Ambas as soluções atingiram qualidade de preparo classificado como bom ou superior em mais de 80% dos pacientes. O uso do bifosfato de sódio determinou menor desconforto e melhor tolerância, apesar de não ter sido superior ao manitol quanto à análise do gosto e presença de efeitos adversos. O bifosfato induziu ao aumento e o manitol a uma redução da osmolaridade, reflexo do que ocorreu com o sódio plasmático nos dois grupos respectivamente. O bifosfato ainda determinou alteração significativa dos níveis séricos de fósforo, cálcio, magnésio e potássio, sem repercussões clínicas. CONCLUSÃO: Ambos os tipos de preparo intestinal determinaram qualidade de limpeza adequada. O bifosfato de sódio, apesar de melhor tolerado, determina maior quantidade de alterações hidroeletrolíticas.

BACKGROUND: To compare the use of sodium biphosphate and 10% mannitol solutions for mechanical bowel preparation in terms of cleansing quality, tolerability, disorder in water and electrolyte balance, and plasma osmolality. METHOD: Sixty patients who had been referred for colonoscopy were analyzed in a randomized, double-blind, prospective study. The quality of bowel cleansing was analyzed by the examiner using Beck's classification. Ingestion tolerability was established by investigating taste, whether the patient felt any discomfort or not, the development of adverse effects and the amount of solution ingested. The following measurements were made before and after ingestion of the oral bowel preparation solution: sodium, potassium, calcium, magnesium, phosphorus, urea, creatinine, glucose, hematocrit, hemoglobin and plasma osmolality. RESULTS: Both solutions resulted in bowel preparations that were classified as good or superior in over 80% of the patients. The use of sodium biphosphate resulted in less discomfort and better tolerance, although it was not superior to mannitol in terms of taste or the presence of adverse effects. Sodium biphosphate led to an increase, and mannitol to a decrease, in osmolality, reflecting the changes in plasma sodium in both groups. The former also resulted in a significant measurement change in serum phosphorus, calcium, magnesium and potassium levels, without any clinical repercussions. CONCLUSION: Both types of bowel preparation resulted in adequate cleansing. Sodium biphosphate, although better tolerated, leads to more alterations in water and electrolyte balance.

Este estudo teve como objetivo avaliar as taxas de resistência de Streptococcus pneumoniae, isolados de pacientes com meningite, à penicilina G, ceftriaxona e vancomicina; avaliar possíveis fatores de risco para resistência antimicrobiana; descrever os sorotipos encontrados e sugerir a terapêutica empírica inicial para meningite. Foram isoladas 100 amostras de S. pneumoniae, encontrando-se 15% de resistência à penicilina, 1% à cefalosporina e 0% à vancomicina. Os sorotipos mais encontrados foram 14 (19%), 3 e 23F (10% cada). Analisando-se os resistentes, o sorotipo 14 (44%) também foi o mais freqüente. Os fatores de risco para resistência de S. pneumoniae encontrados foram: idade menor que um ano (p=0,01) e o uso prévio de antibiótico (p=0,046). As taxas de resistência encontradas, moderada a penicilina, baixa para cefalosporina e nula para vancomicina, sugerem como terapêutica empírica inicial para tratamento da meningite bacteriana aguda de origem comunitária, a cefalosporina de terceira geração isoladamente.

The main objectives of this study are to evaluate the resistance rates of Streptococcus pneumonia to penicillin G, ceftriaxone and vancomycin in patients with meningitis; to analyze possible risk factors to the antimicrobian resistance; to describe the serotypes detected and to suggest an initial empirical treatment for meningitis. The sensitiveness and serotypes of all isolated S. pneumoniae of patients with acute bacterial meningitis received by the Paraná State Central Laboratory from April 2001 to august 2002 have been evaluated. One hundred S. pneumoniae have been isolated, of which 15% were resistant to penicillin, 1% to cephalosporin and 0% to vancomycin. The serotypes most found were 14 (19%), 3 and 23F (10% each). When only the resistant serotypes were analyzed, the most prevalent was the 14 with 44%. The risk factors found in relation to the S. pneumoniae resistance were: age under one year old (p=0.01) and previous use of antibiotic (p=0.046). The resistance rates found, which were moderate to penicillin, low to cephalosporin and neutral to vancomycin, suggest the isolated use of a 3rd generation cephalosporin as an initial empirical therapy for the treatment of acute bacterial meningitis with a communitarian background.

A meningite bacteriana aguda comunitária e a AIDS são doenças prevalentes no Brasil. O objetivo desse estudo foi avaliar a freqüência de meningite bacteriana aguda comunitária entre os pacientes com AIDS e as características clínicas e do líquido cefalorraquidiano (LCR). Foram revistos os dados da Secretaria Municipal da Saúde, Curitiba, Paraná, Brasil, nos anos de 1996 a 2002. Nesse período, 32 pacientes com AIDS preencheram os critérios para meningite bacteriana aguda, representando 0,84% dos casos com AIDS e 1,85% dos casos com meningite bacteriana aguda. A bactéria mais freqüentemente isolada foi S. pneumoniae. A celularidade total e a porcentagem de neutrófilos no LCR foi mais elevada e a glicose foi mais baixa no grupo sem co-infecção (p 0,12; 0,008; 0,04 respectivamente). Bactérias menos freqüentes como agentes etiológicos de meningite podem ocorrer. A taxa de mortalidade elevada entre pacientes com meningite por pneumococo torna a vacinação importante.

Acute communitarian bacterial meningitis and AIDS are prevalent infectious disease in Brazil. The objective of this study was to evaluate the frequency of acute communitarian bacterial meningitis in AIDS patients, the clinical and cerebrospinal fluid (CSF) characteristics. It was reviewed the Health Department data from city of Curitiba, Southern Brazil, from 1996 to 2002. During this period, 32 patients with AIDS fulfilled criteria for acute bacterial meningitis, representing 0.84% of the AIDS cases and 1.85% of the cases of bacterial meningitis. S. pneumoniae was the most frequent bacteria isolated. The number of white blood cells and the percentage of neutrophils were higher and CSF glucose was lower in the group with no HIV co-infection (p 0.12; 0.008; 0.04 respectively). Bacteria not so common causing meningitis can occur among HIV infected patients. The high mortality rate among pneumococcus meningitis patients makes pneumococcus vaccination important.
