1. Percutaneous transhepatic cholangiobiopsy
Resumo Os tumores das vias biliares são, em sua maioria, muito pequenos para apresentarem características específicas por imagem ou para permitir punção percutânea com material suficiente para o diagnóstico. A drenagem biliar trans-hepática percutânea, além de ser uma técnica bem estabelecida no tratamento de icterícia obstrutiva, fornece um aces

2. Development of a Multifunctional Needle for Percutaneous Heart Biopsy and Cell Therapy. A Technical Note
Abstract Validation of transendocardial injection as a method for delivering therapeutic agents to the diseased heart is increasing. Puncture heart biopsies should re-emerge as a possible alternative method to allow access to the myocardium and implantable biomaterial for cell therapy. Therefore, this work aims to present a percutaneous puncture device for b

3. Lesion aspirate culture for the diagnosis and isolation of Leishmania spp. from patients with cutaneous leishmaniasis
The detection of Leishmania spp. in skin lesion aspirates, using a puncture technique, was evaluated in 76 patients with cutaneous leishmaniasis (CL) who were referred to a Leishmaniasis Reference Centre in Brazil. CL was defined based on skin lesions suggestive of the disease and on a positive result of the Montenegro skin test or Giemsa-stained imprints of

4. Avaliação por processamento de imagem assistida por computador das alterações citométricas dos adipócitos do tecido celular subcutâneo da parede anterior do abdome, após hipercapnia local / Analysis of adipocytes changes by computer-assisted imaging process in abdominal wall adipose tissue after local hypercapnia
Recent researches have demonstrated the beneficial effects of percutaneous infiltration of carbon dioxide in different fields of medicine. Currently, this therapy proves to be an alternative for treatment of localized fat deposits formed after lipectomy of the abdominal wall. The effects appear to be related to the ability of therapy to increase local blood

5. Segurança da anestesia geral para punção lombar e aspirado/biópsia de medula óssea em pacientes oncológicos pediatricos
Introdução: Procedimentos dolorosos de curta duração como o aspirado/biópsia de medula óssea e a punção lombar, com ou sem quimioterapia intratecal, são realizados com freqüência durante o tratamento de crianças com câncer. Estudos examinando diversos métodos de sedação para crianças submetidas aos procedimentos dolorosos têm mostrado difer

6. Transthoracic needle biopsy of thoracic tumours by a colour Doppler ultrasound puncture guiding device.
BACKGROUND--Ultrasound guided transthoracic needle aspiration biopsy has recently been used to obtain specimens for histological diagnosis of pulmonary and mediastinal tumours. Conventional real time, grey scale puncture guiding devices cannot differentiate vascular structures, and clear visualisation of the needle shaft or tip within a desired target is not

7. Intercostal arteriovenous fistula due to pleural biopsy.
A 32 year old woman had a pleural biopsy for a left pleural effusion, which showed caseating granuloma typical of tuberculosis. When the fourth biopsy specimen was removed considerable bleeding occurred from the puncture site. Four days later a bruit was audible over the punctured area, radiating to the back. Eight days after the procedure the patient had a

8. Infectious discitis caused by Enterobacter cloacae.
The case is reported of a patient who developed a vertebral osteomyelitis caused by Enterobacter cloacae. The organism was isolated in cultures of blood and vertebral puncture biopsy samples. The patient was satisfactorily treated with trimethroprim and sulphamethoxazole. Enterobacter cloacae, a Gram negative organism, has been confirmed as the cause of bact

9. Prevention of pneumothorax in needle lung biopsy by breathing 100% oxygen
In an attempt to decrease pneumothorax after transthoracic needle lung biopsy we evaluated the effect of breathing 100% oxygen during the procedure. Fifty consecutive biopsies on 46 hospital patients were performed on subjects breathing either oxygen or compressed air. The selected gas, chosen randomly, was given for five minutes before the biopsy and contin

10. A polymerase chain reaction assay of cerebrospinal fluid in patients with suspected herpes simplex encephalitis.
A polymerase chain reaction (PCR) was used to detect herpes simplex virus (HSV) deoxyribonucleic acid (DNA) in CSF of 109 patients with possible herpes simplex encephalitis. HSV DNA was found in 20/109 patients. In 14 of these patients the diagnosis was confirmed by a rise in CSF antibodies, isolation of HSV from the brain, or both. In 3 patients CSF antibod
