    Notes: In a Swedish series of 107 invasive squamous carcinomas of the cervix, DNA extraction from paraffin-embedded material was successful in 97 cases. The prevalence of human papillomavirus (HPV) in this material was 86.6%, as determined by polymerase chain reaction (PCR) using both consensus and type-specific primers. HPV type 16 was most common (42.3%; other types were 31 (12.3%), 18 (9.3%) and 33 (10.3%). Seventeen cases (17.3%) were positive for the consensus primers only and were regarded as HPV of unknown type. There was no significant difference in corrected survival between patients with HPV-positive or -negative tumors. In the HPV-positive group, patients with tumors containing HPV 33 or HPV 18 had a significantly poorer prognosis than patients with tumors containing other types of HPV DNA (relative hazard 3.18, 95% confidence interval 1.37–7.39, P = 0.007), implying a prognostic significance of HPV type.

    Notes: Abstract Blood concentrations of doxo- and epirubicin were studied in mice after i.v. or i.p. administration under normal and hypothermic conditions. The animals either were pretreated i.p. with chlorpromazine at 15 mg/kg and allowed to cool to a rectal temperature of 28 °C or were given saline i.p. with their rectal temperature remaining at 37 °C. The anthracyclines were 14-14C-labeled and were given at a dose of 0.85 mg/kg. Blood samples were taken at 5, 15, and 25 min and 2, 6, 24, and 48 hours after injection and were analyzed by liquid scintillation counting. The blood concentration related to time was similar for the two anthracyclines. The peak concentration was highest for i.v. administration and was higher for the hypothermic groups. The peak concentration and the area under the curve were highest under hypothermic conditions. The terminal half-life was longer after i.p. administration. The ratio calculated for the blood concentration under hypothermic/normothermic conditions over time was substantially increased after i.p. administration, the increase being most pronounced for epirubicin. The pharmacokinetic characteristics found might be related to the anthracycline toxicity encountered in tumor-inoculated mice treated at different body temperatures.

    Description / Table of Contents: Résumé Lors des ruptures traumatiques, il est souvent impossible de suturer la rate. Les conséquences de la splénectomie sont représentées par une augmentation des infections avec un fort taux de mortalité. L'autotransplantation du tissu splénique a été proposé mais sa valeur fonctionnelle est toujours mise en doute en particulier en ce qui concerne l'aptitude de la rate autotransplantée à résister à la sépticémie. Les auteurs étudient l'aptitude à sequestrer les hématies dénaturées marquées aux99mTc (technetium-99m) globules rouges (RBC) et la résistance contre le pneumocoque par voie intraveineuse chez des rats témoins opérés sans splénectomie, des rats splénectomisés et des rats splénectomisés avec autotransplantation splénique. Des examens histopathologiques sont aussi pratiqués. Il existe une augmentation graduelle dans la séquestration splénique des hématies marquées avec un rapport rate-sang de 0.19 à 1.5 à la deuxième et la trentième semaine après la réimplantation splénique. Aucun rat n'a survécu à l'injection de pneumocoque avant les 18 semaines et après autotransplantation, alors que à partir de la 28-ième à la trentième semaine, 80% des rats ont survécu à l'infection indiquant une augmentation de l'activité splénique à cette période. De même il a été observé une augmentation du poids tissulaire splénique concomittante de 241 mg au moment de l'autotransplantation, à 417 mg à partir de la 24 ème semaine après réimplantation. Quatre à 5 semaines après la transplantation, la rate a pratiquement récupéré une architecture histologique normale. Cette étude indique que le tissu splénique autotransplanté est capable de récupérer sa capacité de résistance contre l'infection par le pneumocoque injecté par voie intraveineuse, de séquestration des hématies dénaturées marquées au99mTc et enfin de régénération du tissu splénique normal 24 à 30 semaines après la réimplantation.
    Abstract: Resumen En caso de ruptura traumática, con frecuencia no es posible reparar el bazo. La esplenectomá resulta en una susceptibilidad aumentada a la sepsis, con elevadas tasas de mortalidad. El autotransplante de tejido esplénico ha sido propuesto, pero su capacidad funcional se halla todavía en duda, particularmente en cuanto a su habilidad para resistir el desafío de una inyección bacteriana intravenosa. La habilidad para secuestrar corpúsculos rojos desnaturalizados y marcados con tecnecio-99m (Tc-99m CR) y de resistir neumococos intravenosos fue estudiada en operaciones fantasmas (Sham) en ratas controles, en ratas esplenectomizadas, y en ratas esplenectomizadas con bazos autotransplantados. Estudios histopatológicos también fueron realizados. Se observó un incremento gradual en el secuestro esplénico de los Tc-99m RC con una relación de bazo a sangre de 0.19 a 1.5 a las 2 y 30 semanas después de la reimplantación esplénica. Con anterioridad a las 18 semanas del autotransplante esplénico, ninguna rata sobrevivió a la inyección intravenosa de neumococos, pero a las 28–30 semanas, 80% de las ratas sobrevivieron este desafío, lo cual es indicativo de una actividad esplénica incrementada hacia esta época. También se produjo un aumento correspondiente del peso del tejido esplénico de 241 mg en el momento del autotransplante a 417 mg comenzando la 24a semana después de la reimplantación. Cuatro a 5 semanas después del transplante, los bazos exhibían una arquitectura histológica bastante normal. En conclusión, el presente estudio indica que el tejido esplénico autotransplantado es capaz de restaurar la habilidad de resistir el desafío de una inyección intravenosa de neumococos, de secuestrar Tc-99m CR, y de regenerar tejido esplénico normal en el curso de 24–30 semanas después de la reimplantación.
    Notes: Abstract In traumatic rupture, it is often not possible to repair the spleen. Splenectomy results in increased susceptibility to sepsis with a high mortality rate. Autotransplantation of splenic tissue has been suggested, but its functional value is still in doubt, particularly the ability of autotransplanted spleen to resist intravenous bacterial challenge. The ability to sequestrate denatured99mTc (technetium-99m) RBC (red blood cells) and to resist intravenous pneumococci was studied in sham-operated (control) rats, splenectomized rats, and splenectomized rats with autotransplanted spleen. Histopathologic tests were also performed. There was a gradual increase in the splenic sequestration of the denatured99mTc RBC with a spleen-to-blood ratio of 0.19 to 1.5 at 2 and 30 weeks after the splenic reimplantation. Prior to 18 weeks after the splenic autotransplantation, no rat survived the intravenous pneumococcal challenge, but at 28–30 weeks, 80% of the rats survived the challenge indicating an increased splenic activity at this time. There was also a corresponding increase in splenic tissue weight from 241 mg at the time of autotransplantation to 417 mg beginning at the 24th week after the reimplantation. Four to 5 weeks after the transplantation, the spleens had a fairly normal histological architecture. The present study, therefore, indicates that autotransplanted splenic tissue is capable of restoring the ability to resist intravenously injected pneumococcal challenge, to sequestrate denatured99mTc RBC, and to regenerate normal splenic tissue within 24–30 weeks after the reimplantation.

    Notes: Abstract Pericardial effusions were found in 6 of 10 children with carbohydrate-deficient glycoprotein syndrome type I (CDGS-I). In three cases pericardectomy was necessary. Blood concentrations of several glycoproteins and albumin were low. Similar abnormal isoforms of four glycoproteins were found in blood (B) and pericardial fluid (PF). There was a significant negative correlation between the mean concentration ratio PF/B and the molecular mass (MW) of 11 proteins. For proteins with MW 〈100 kDa there were significant correlations in the controls, but not in the patients, between the PF/B ratio and both the MW and the sialic acid contents in the (glyco-)proteins. The pericardium exhibited focal mixed inflammatory changes with mesothelial proliferation, with widened endoplasmic reticulum and flocculent and/or lamellated material. Damage to a pericardial protein barrier is suggested to be involved in pericardial effusion in CDGS-I.
