    Notes: Transfemoral plug closure of PDA (patent ductus arteriosus), which was originally introduced by Porstmann in 1968, was successful in 73 of 74 consecutive patients at Osaka Prefectural Hospital. Some instrumental and technical modifications were made. There has been no mortality, and no dis-lodgment of the plug occurred after the modified plug with a barbed head was used although a major complication during the procedure was the dislodgment of the plug into the aorta, which occurred early in three cases. There was no recurrence of shunting or any other complications in the long-term follow-up studies. For the patient with a simple isolated PDA over 3 years of age, the catheter technique is considered to be the method of choice to close the ductus. (J Interven Cardiol 1991; 4:295–300)

    Description / Table of Contents: Résumé Afin d'évaluer l'efficacité de la chimiothérapie primaire dans le lymphome gastrique au début, on a administré une multichimiothérapie avant la chirurgie. Cinq patients ayant un lymphome gastrique primitif stades IE or IIE (âge 54–65 ans, 3 hommes et deux femmes) ont été traités par une multichimiothérapie suivie de chirurgie. Chez tous les patients, le diagnostic avait été établi par les biopsies obtenues en endoscopie. Deux patients avaient un lymphome stade IE et trois avaient un lymphome stade IE. Selon la classification histopathologique, un patient avait um lymphome diffus à grandes cellules alors que l'autre avait une maladie diffuse à cellules moyennes. Tous les patients ont reçu deux cycles de VEPA toutes les quatre semaines. Entre 16 et 44 jours après la fin de la chimiothérapie, une gastrectomic totale, une adénolymphectomie régionale associée à une résection pancréatique et une splénectomie ont été pratiquées. Les ganglions régionaux étaient augmentés de volume chez quatre des patients. II n'y avait aucune cellule maligne résiduelle dans les pièces de résection gastrique. Aucun des patients n'avait de récidive entre 12 et 40 mois après l'intervention. La chimiothérapie primaire seule provoquait la disparition de cellules malignes dans les lymphomes gastriques stades IE/IIE. Nos résultats suggèrent que la chirurgie n'est pas indispensable dans le traitement du lymphome gastrique au début.
    Abstract: Resumen con el propósito de determinar la eficacia de la quimioterapia primaria en el tratamiento de los pacientes con linfoma gástrico temprano, se administró quimioterapia de múltiples agentes antes de la cirugía y los resultados han sido informados. Cinco pacientes con Estadíos IE y IIE de linfoma gástrico primario (54–65 años, 3 hombres y 2 mujeres) fueron tratados con quimioterapia combinada con anterioridad a la resección gástrica. El diagnóstico fue establecido mediante biopsia endoscópica en la totalidad de los pacientes. Dos pacientes presentaban enfermedad en Estadío IE y tres en Estadío IIE. La clasificación histopatológica fue la siguiente: linfoma difuso de células grandes, uno; difuso de células de tamaño intermedio, cuatro. Todos los pacientes recibieron dos ciclos de VEPA cada cuatro semanas. En el día 16–44 luego de completar la quimioterapia se practicó gastrectomía total con disección sistemática de los ganglios linfáticos regionales y resección de la cola del páncreas y esplenectomía. En cuatro pacientes se observó aumento del tamaño de los ganglios linfáticos regionales. En todos los cinco pacientes el examen histológico reveló que no había células residuales del linfoma en ele specimen resecado. Ningún paciente presentó evidencia de recurrencia en 12 a 40 meses luego de la cirugía. La quimioterapia primaria de por sí resultó en la desaparición de las células malignas en el linfoma gástrico en Estadíos IE/IIE. Nuestros resultados sugieren que la cirugía puede no ser un procedimiento esencial en el tratamiento del linfoma gástrico en estadios tempranos.
    Notes: Abstract to assess the efficacy of primary chemotherapy for treatment of early stage patients with gastric lymphoma, multiple agent chemotherapy was given to patients prior to surgery. Five patients with stages IE and IIE of primary gastric lymphoma (54–65 years of age; three men, two women) were treated with multiple agent chemotherapy prior to gastric resection. In all patients the diagnosis was established by endoscopic biopsy. Two patients had stage IE disease, and three had stage IIE. Histopathologically, there was one diffuse large cell lesion and four diffuse medium cell tesions. All patients received two cycles of VEPA every 4 weeks. On the 16th to 44th day after completion of chemotherapy, total gastrectomy, systematic dissection of regional lymph nodes with resection of the caudal pancreas, and splenectomy were performed. Swelling of the regional lymph nodes was noted in four cases. In all five cases, histologic findings revealed no residual cells of malignant lymphoma in the resected specimen. None of the patients had no evidence of recurrence at 12 to 40 months after surgery. Primary chemotherapy alone thus resulted in the disappearance of malignant cells in stage IE/IIE gastric lymphoma. Our reatment of early stage gastric lymphoma.

    Notes: Abstract Extensive intrahepatic portal-hepatic venous shunts are extremely rare, and to our knowledge, this condition accompanied by an arterioportal shunt has never before been reported. We have recently encountered such a case with marked intrahepatic portal-hepatic venous shunts and intrapancreatic arterio-portal shunts. Our angiographic and computed tomographic (CT) findings of these complications are described in this report.

    Notes: Abstract Radiographs of 12 carcinoid tumors of the rectum were reviewed and compared with pathologic findings. There was a good correlation between the radiologic and pathologic findings with respect to tumor invasion and extent. Nine tumors that radiologically presented a smooth round defect less than 2.0 cm in diameter did not invade the muscular layer and did not metastasize. Three tumors that presented a deep crater with an irregular edge greater than 2.0 cm were found to have invaded the muscular layer and metastasized to the lymph nodes or the liver. The double-contrast enema showed an excellent detection rate; no lesion was missed by it.

    Notes: Summary In order to observe glucose transport into the brain, 6-[N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino]-6-deoxyglucose (NBDG), a non-metabolizable and fluorescent glucose analogue, was injected intravenously into mice. After ascertaining that this glucose analogue is non-metabolizable in the brain, the NBDG contents in the blood and brain were measured quantitatively by spectrofluorimetry at 0, 0.5, 2, 5, 10 and 30 min after intravenous injection. The NBDG content in the blood decreased markedly with time, whereas in the brain it rapidly decreased, then gradually increased after 2 min. Glucose transport into the hippocampus was observed with a confocal laser scanning microscope. At 0.5 min, NBGD was seen to be highly concentrated on the vascular wall. Using the confocal mode, it was found that the fluorescence was unevenly distributed on the microvessel wall, suggesting local differences of glucose transport in the vascular wall. At 5 min, the fluoresent intensity of the vascular wall was markedly decreased, whereas relatively intense fluorescence was observed in the cerebral parenchyma of the stratum lacunosum-moleculare and stratum pyramidale of CA3. At 10 min, a weak fluoresence was diffusely distributed in the hippocampus. As to the localization of NBDG in the brain, capillary endothelium (luminal and abluminal membrane), basement membrane, and the feet of the astrocytes are discussed.
