ABSTRACT Burkitt's lymphoma is a B-cell non-Hodgkin lymphoma that has been called by most researchers the fastest growing human tumor, as it is capable of achieving a cell doubling rate between 24 and 26 hours. We present a 48-year-old male patient with a diagnosis of Burkitt's lymphoma, immunocompetent, with giant splenomegaly and spontaneous splenic rupture as a complication. The patient had an unfavorable evolution in a short period of time. Burkitt's lymphoma is a highly aggressive disease, where lack of clinical suspicion and untimely diagnosis overshadow the prognosis.

RESUMEN El linfoma de Burkitt es un linfoma no Hodgkin de células B que ha sido denominado por la mayoría de los investigadores como el tumor humano de crecimiento más rápido, pues es capaz de lograr una tasa de duplicación celular entre 24 y 26 horas. Se presentó un paciente masculino de 48 años de edad, con diagnóstico de linfoma de Burkitt, inmunocompetente, con esplenomegalia gigante y rotura esplénica espontánea como complicación. El paciente tuvo una evolución desfavorable en un breve período de tiempo. El linfoma de Burkitt es una enfermedad altamente agresiva, donde la falta de sospecha clínica y diagnóstico no oportuno ensombrecen el pronóstico.

RESUMO Objetivo Verificar o tempo despendido na transição da alimentação por gavagem para via oral exclusiva, na técnica sonda-peito, comparando RNs baixo peso, considerando suas intercorrências clínicas/médicas, submetidos ao peito exclusivo com aqueles que, além do peito, receberam complemento por copo/mamadeira. Método Estudo de coorte, analítico e longitudinal, com 165 RNs, divididos quanto à gravidade de intercorrências clínicas (G1 e G2) e quanto à via de dieta (A e B). Todos RNs eram baixo peso, do Método Canguru, estimulados no peito, conforme prescrição médica e rotina hospitalar. Pertenciam ao subgrupo A: RNs estimulados exclusivamente no peito, que mantiveram peito exclusivo no momento da alta, e ao subgrupo B: RNs que utilizaram copo/mamadeira em algum momento da internação hospitalar em complementação ao peito. Foi registrado o número de dias que o RN permaneceu em cada etapa da transição. Resultados O histórico de intercorrências médicas influenciou significativamente o tempo total de transição. Subgrupos G1-A (10 dias), G1-B (9 dias) e G2-A (12 dias), quando comparados ao grupo G2-B(16 dias), evidenciaram maior chance de alta antecipada. Conclusão RNs sem intercorrências clínicas importantes apresentaram chance de alta mais breve. RNs com intercorrências clínicas, que fizeram a transição da gavagem exclusivamente no peito, tiveram tempo de transição menor que aqueles que utilizaram complementação por copo/mamadeira. A transição alimentar pela técnica sonda-peito é importante para ser preconizada na atuação fonoaudiológica em Neonatologia.

ABSTRACT Purpose Measure the intervention time required for transition from gavage to exclusive oral feeding, comparing newborns exposed exclusively to the mother’s breast with those who, in addition to breastfeeding, received supplementation using a cup or baby bottle. Methods Analytical, longitudinal, cohort study conducted with 165 newborns (NB) divided into groups according to severity of medical complications (G1-with no complications; G2-with significant complications), and into subgroups according to feeding mechanism (A and B). All NBs were low birth weight, on Kangaroo Mother Care, and breast stimulated according to medical prescription and hospital routine. Regarding feeding pattern, subgroup A comprised NBs exclusively breastfed at hospital discharge, whereas subgroup B was composed of NBs fed through cup/bottle at some time during hospitalization. The number of days spent in each stage of transition was recorded for each NB. Results History of clinical complications significantly influenced total intervention time. Study participants in subgroups G1-A (10 days), G1-B (9 days), and G2-A (12 days) displayed greater chances of early discharge compared with those in subgroup G2-B (16 days). Conclusion NBs with no important history of clinical complications displayed greater chances of early hospital discharge. NBs with significant history of clinical complications that underwent gavage to exclusive breastfeeding transition presented smaller intervention time than those that required supplementation using cup/bottle. Feeding transition using the gavage-to-exclusive oral feeding technique is recommended for Speech-language Pathology practice in Neonatology.

OBJETIVO: Descrever a distribuição escolar de um grupo de crianças e adolescentes com paralisia cerebral (PC) e analisar o impacto da função motora grossa e outros déficits no processo de inclusão. MÉTODOS: Estudo prospectivo de pacientes do Ambulatório de Paralisia Cerebral da Universidade Federal do Paraná, avaliados em 2005. Pais ou cuidador completaram um questionário com dados relativos a: tipo de escola frequentada, dificuldades do aprendizado e necessidade de suporte psicopedagógico e fonoaudiológico. Os dados obtidos incluíram quem era o cuidador primário, seu nível de escolaridade e renda. As variáveis coletadas dos prontuários foram antecedentes perinatais e pós-natais, classificação topográfica da PC e função motora (Sistema de Classificação Motora Grossa - SCFMG), classificação da fala e presença de epilepsia. RESULTADOS: 105 crianças e adolescentes foram incluídos. A média de idade foi 10,8 anos, 61 (58%) masculinos. Dentre as 105 crianças, 97 (92%) frequentavam a escola, 36 (34%) em classe regular, 7 (6,5%) em classe especial e 54 (51%) em escola especial. Crianças que frequentavam a escolar regular apresentavam predominantemente SCFMG nível I ou II, hemiplegia, epilepsia ausente ou com bom controle e fala normal ou disartria. Aqueles em escola especial eram crianças com SCFMG níveis III, IV e V, diplegia ou tetraplegia, epilepsia refratária e atraso na fala ou sua ausência. CONCLUSÕES: Até o momento, a inclusão de crianças com PC em escolas regulares parece trazer benefícios para aquelas com hemiplegia, nível I ou II do SCMFG, sem epilepsia e com fala normal.

OBJECTIVE: To describe the school distribution of a group of children and adolescents with cerebral palsy (CP) and to analyze the impact of gross motor function and other deficits in the inclusion process. METHODS: Prospective study of patients from de Outpatient Clinic for Cerebral Palsy of the Federal University of Paraná, Brazil, in 2005. Parents or caregivers completed a questionnaire about type of school attended at the moment, learning disabilities, and need for psychopedagogic and speech-language support. Data collected included who was primary caregiver, his/her school level and per capita income. Data obtained from medical records were: perinatal and post natal antecedents, topographic classification of CP and motor function (Gross Motor Function Classification System - GMFCS), speech classification and presence of epilepsy. RESULTS: 105 children and adolescents were included. Mean age was 10.8 years old and 61 (58%) were male; 97 (92%) attended school, with 36 (34%) in regular classes, 7 (6.5%) in special classes and 54 (51%) in special schools. Most of the children attending regular school had GMFCS level I or II, hemiplegia, absence of epilepsy or good control of seizures and either normal speech or dysarthria. Those in special schools had GMFCS levels III, IV or V, diplegia or tetraplegia, refractory epilepsy and a delayed speech or muteness. CONCLUSIONS: Up to now, inclusion of children with CP in regular schools proved to be indicated for those hemiplegic, with GMFCS level I or II, without epilepsy and with normal speech.

The cotton plant, Gossypium hirsutum, hosts various pests that damage different structures. Among these pests, Spodoptera cosmioides (Walker) and Spodoptera eridania (Cramer) (Lepidoptera: Noctuidae) are considered important. The objectives of this study were to characterize and to quantify the potential damage of S. eridania and S. cosmioides feeding on different structures of cotton plants. For this purpose, newly-hatched larvae were reared on the following plant parts: leaf and flower bud; leaf and boll; flower bud or boll; and leaf, flower bud and boll. The survival of S. cosmioides and S. eridania was greater than 80% and 70% for larvae fed on cotton plant parts offered separately or together, respectively. One larva of S. eridania damaged 1.7 flower buds, but did not damage bolls, while one larva of S. cosmioides damaged 5.2 flower buds and 3.0 cotton bolls. Spodoptera eridania and S. cosmioides can be considered species with potential to cause economic damage to cotton plants because they can occur throughout cotton developmental stages causing defoliation and losses of reproductive structures. Therefore, the results validate field observations that these two species of Spodoptera are potential pests for cotton.

In this work, the survey of simuliid species and the study of their spatial distribution in four streams of a small watershed situated in Londrina, Paraná State, were carried out from January to October 2007. Changes in the species composition of the breeding sites were also checked along the sampling months. Seventeen black fly species were found, being Simulium botulibranchium Lutz, Simulium travassosi d'Andretta & d'Andretta, Simulium anamariae Vulcano, Simulium brachycladum Lutz & Pinto and Simulium metallicum s. l. Bellardi new records for Paraná State. The Canonical Correspondence Analysis showed that the environmental variables most correlated to the species distribution among sample sites were water conductivity and those linked to physical dimensions of the breeding sites, like width, depth and water velocity. The matrix of faunistic similarity among collecting dates was negatively correlated to the time interval of sampling matrix for three of the water bodies studied, showing the existence of temporal changes in the species composition. According to Multiple Regression Analysis, temporal abundance variation of Simulium perflavum Roubaud, Simulium inaequale Paterson & Shannon and Simulium lutzianum s. l. Pinto was not linked to air temperature, photoperiod and rainfall, suggesting the influence of other factors, probably those directly associated to specific breeding site conditions. The results indicate that differences in physical and chemical characteristics among water bodies may affect the taxonomic composition of simuliids in this watershed.

De fevereiro de 2000 a setembro de 2001, 84 pacientes apresentando fratura do anel pélvico foram avaliados, segundo determinado protocolo aplicado. Houve predomínio do sexo masculino (67%), a maioria dos pacientes eram brancos (86%) e a idade média foi de 37 anos. Quanto ao tipo de acidente, os mais freqüentes foram os relacionados ao trânsito (58%) - carro, moto e atropelamento - pacientes vítimas de traumas de alta energia. As fraturas foram classificadas de acordo com Tile(13) em estáveis, em 55% (fraturas do tipo A); rotacionalmente instáveis, em 30% (fraturas do tipo B) e rotacional e verticalmente instáveis, em 15% (fraturas do tipo C). A fratura mais freqüentemente encontrada foi a dos ramos isquiopúbicos. O tratamento cirúrgico foi realizado em 29% dos pacientes. Houve necessidade de transfusão sangüínea em 20% dos pacientes, utilizando-se uma média de cinco unidades de sangue total; exceto dois pacientes (2,4%) com lesão arterial intra pélvica que necessitaram mais de 10 unidades de sangue nas primeiras 48 horas. A mortalidade foi de sete por cento tendo relação significativa com traumas extra pélvicos.

From February 2000 to September 2001, 84 patients with pelvic fractures were assessed, using a determined protocol. There were more men (67%) than women. Most of the patients were white (86%) and the average was 37 years of age. The most frequent accident was reported to have been traffic accidents (58%) such as motor vehicle, motorcycle and running over - victims of high-energy injuries. The pelvic ring fractures were classified according to Tile (13) as stable in 55% (type A injury), as rotationally unstable in 30% (type B injury) and as unstable in translation in 15% (type C injury). The most frequent lesion affecting the pelvic girdle was the isquiopubic bones fracture (transpubic instability). The overall rate of operative stabilization was 29%. An average of five units of total blood transfusion was required in 20% of the patients; exception to two (2,4%) patients with intrapelvic arterial injury that required more than 10 units of blood in the first 48 hours. The overall mortality rate was 7%, depending significantly on the associated extrapelvic traumas.
