Evaluación imaginológica de un caso de histiocitosis durante tres años / Imaging evaluation of a case of histiocytosis for three years

La histiocitosis de células de Langerhans es un trastorno celular dendrítico, resultado de la proliferación clonal de este tipo de células, morfológicamente redondeadas e inmaduras inmunofenotípica y funcionalmente; asociadas con eosinófilos, macrófagos, linfocitos y células multinucleadas gigantes, en ocasiones. Puede presentarse de forma monosistémica, cuando afecta a un solo sitio u órgan; o multisistémica cuando se presenta en múltiples órganos o sistemas corporales. La literatura médica y las publicaciones en las que se asocia la imaginología al estudio y caracterización de las enfermedades hematológicas son escasas, aun en la era tecnológica. En este trabajo se presenta un caso de histiocitosis de células de Langerhans que fue seguido imaginológicamente durante 3 años con el consiguiente apoyo al diagnostico, tratamiento, seguimiento y valoración; lo que demuestra la utilidad de la Imaginología como herramienta para lograr un mejor manejo del paciente y como principio de la atención medica multidisciplinaria(AU)

Langerhans cells histiocytosis is a dendritic cell disorder, result of clonal proliferation of this type of cells, morphologically rounded and immature immunophenotypically and functionally; associated with eosinophils, macrophages, lymphocytes and giant multinucleated cells at times. It can present monosystemic, affecting a single site or organ; or multisystemic disease when present in multiple organs or body systems. Medical literature and publications in which imaging is associated with the study and characterization of hematological diseases are scarce, even in the technological era. This paper presents a case of Langerhans cells histiocytosis that was followed imaging during 3 years with the subsequent support to diagnosis, treatment, monitoring and evaluation; demonstrating the usefulness of imaging as tool to achieve better patient management and as a principle of multidisciplinary medical care(AU)

Embarazo heterotópico espontáneo. Reporte de caso / Heterotopic spontaneous pregnancy. Report of case

Fundamento. La combinación de un embarazo intrauterino con uno extrauterino se conoce como embarazo heterotópico, esta es una patología poco reportada cuando se presenta en forma espontánea (1 caso cada 20 000 o 30 000 embarazos). Objetivo: Reportar un caso la infrecuencia de la forma en que se presenta la combinación de los dos embarazos y la emergencia de cuando uno está roto. Presentation of the case: Paciente de 26 años de edad, con el antecedente de tres gestaciones previas (tres partos a término); presentó una historia de amenorrea de tres meses asociada a dolor hipogástrico de 24 horas de evolución. Al examen físico tenía la TA de 90/50 mHg, el pulso de 120 pulsaciones por minutos, frialdad y sudoración, la temperatura axilar de 36,4 °C. Su abdomen estaba levemente distendido, blando, depresible, con ruidos hidroaéreos, sensible a la palpación profunda en hipogastrio y en fosa ilíaca derecha con Blumberg negativo. Se le realizó una laparotomía exploradora con el diagnóstico presuntivo de embarazo ectópico derecho, y se observó en ésta un hemoperitoneo de 500 ml, útero, ovario y trompa izquierdas normales. Se le realizó una ecografía que informó un embarazo intrauterino de primer trimestre, que al momento de la cirugía tenía una edad gestacional estimada de 15 semanas. Conclusiones: El diagnóstico del embarazo heterotópico no es fácil definirlo debido a las diversas manifestaciones clínicas y a la existencia del embarazo intrauterino que continúa; se debe tener en cuenta que la ecografía es un pilar importante en el diagnóstico e identificación temprana de esta patología.

Background: The combination of an intra-uterine pregnancy with an extra uterine one is known as heterotopic pregnancy, this is a pathology little reported when it is presented in an spontaneous form (1 case each 20 000 or 30 000 pregnancies). Objective: To report a case the seldomness in the way in that it is presented the combination of the two pregnancies and the emergency of when one is broken. Report of case: Patient of 26 years old, with the antecedent of three previous pregnancies (three childbirths to term);she presented a history of a three months amenorrhea associated to hypogastria pain of 24 hours of evolution. To the physical exam she had the TA of 90/50 mHg, the pulse of 120 pulsations for minutes, indifference and sweating, the axillary temperature of 36, 4 °C. Her abdomen was slightly loosened, soft, depressive, with noises hydro air, sensitive to the deep palpation in hypogastrium and in grave right iliac with negative Blumberg. It was carried out an exploratory laparotomy with the presumptive diagnosis of right ectopic pregnancy, and it was observed in this a hemoperitoneum of 500 ml, uterus, lefts ovary and trumpet normal. It was carried out an ultrasound that informed an intra-uterine pregnancy of first trimester that had an estimated gestational age of 15 weeks at the moment of the surgery. Conclusions: The diagnosis of the heterotopic pregnancy is not easy to define due the diverse clinical manifestations and the existence of the intra-uterine pregnancy that continues; it should be kept in mind that the ultrasound is an important pillar in the diagnosis and early identification of this pathology.

Histiocitosis de células de Langerhans e imágenes diagnósticas / Langerhans cell Histiocytosis and diagnostic images

Resumen El objetivo del artículo es presentar el caso de un paciente que consultó al servicio de imaginología por dolor en la región costal, y quien posteriormente fue diagnosticado como histiocitosis de células de Langerhans. Se pretende proveer al lector una breve revisión de tema de imágenes diagnósticas de esta enfermedad para que el reconocimiento de la misma permanezca dentro de la lista de diagnósticos diferenciales.

Abstract The goal of this article is to provide readers with a case presentation of a patient who presented to the radiology department for pain located at the costal region, which later was diagnosed as Langerhans cell histiocytosis (LCH). We pretend with this article to provide a brief, complete and efficient literature review regarding the topic of imaging on this pathology. This was done with the objective of providing the reader with a brief and concise literature review so that this disease entity can remain within the list of differencials.

Saúde bucal do idoso atendido na Policlínica Geral do Rio de Janeiro: uma análise radiográfica / Oral health status of elderly patients with consultations at the General Polyclinic of Rio de Janeiro: a radiographic analysis

O objetivo do presente trabalho foi realizar um perfil epidemiológico da saúde bucal de idosos atendidos na Policlínica Geral do Rio de Janeiro. Foram avaliados quarenta e oito exames radiográficos, selecionados aleatoriamente do arquivo de prontuários odontológicos, de pacientes idosos atendidos na Policlínica Geral do Rio de Janeiro, por um único examinador, utilizando negatoscópio. Os dados foram armazenados e PS percentuais analisados. Os resultados evidenciaram 46% de edentulismo e em 56% dos casos dentes presentes. Dos dentes presentes, 37% eram acometidos por doença periodontal, 24% apresentavam prótese unitária, 20% continham obturações, 15% apresentavam tratamento endodôntico e 2% tinham restos radiculares. Os resultados do presente estudo são similares aos achados na literatura, fazendo-se necessário maior ênfase no tratamento odontológico dos idosos.

The aim of this study was to establish an oral health status of elderly patients with consultations at the General Polyclinic of Rio de Janeiro. Forty-eight radiographs exams, randomly selected, were evaluated by a single examiner using lightbox. Data were stored and analyzed. The results showed 44% (Na versão em Português consta 46%) of edentulousness and 56% of patients with teeth. In the last case, 37% had periodontal disease; 24% had unitary prostodontic; 20% had restorations; 15% had endodontic treatment and 2% still had radicular roots. The results of this study were similar to the literature, which emphasizes the need for dental treatment in the elderly population.

Imaginological study on resombinant artificial bone substitute for experimental bone defects / 中国矫形外科杂志

[Objective]To investigate the ability of repairing bone defect with the combination of recombinant human insulin-like growth factor-1(rhIGF-1),coralline hydrolyapatite(CHA) and autogeneous red bone marrow(ARBM) by way of imaginology.[Method]Bilateral middle radius periosteum-bone defects (11mm in length) were created in 54 Chinese rabbits,and were ramdonly devided into 6 groups(each group containning 18 radial defects of one forearm): group A, defects transplanted with rhIGF-1/CHA/ARBM,group B,with CHA/ARBM,group C,with rhIGF-1/CHA,group D,with CHA,group E,with autograft,group F,no implant.At 2,4,8,and 12 weeks postoperation,the repair effects of defects were evaluated by observation of gross appearance,roengenodiagnosis and radionuclide bone image assay.[Result]In group A,radiological and bone density image analysis showed that the defects were bridged well at 12 weeks postoperatively and was significantly superior to those of any other groups(P0.05).[Conclusion]The recombinant compound rhIGF-1/CHA/ARBM,which possesses the potential ability of osteogenesis,osteocondution and osteoinduction for bone defect repairing,can enhance bone healing and serve as a new type of bone substitute.
