Atraumatic rupture of the spleen in periarteritis nodosa.

A case of atraumatic rupture of the spleen is described. The underlying disease was found to be periarteritis nodosa. Involvement of the spleen is common in this disease, but to our knowledge atraumatic rupture of this organ in a patient with histologic verified periarteritis nodosa has not previously been reported. In the present case the splenic rupture was the incident which led to the diagnosis. A possible mechanism of the rupture is proposed.

Factor VIII-related antigen and lymphatic collecting vessels.

In order to investigate endothelial cells of lymphatic vessels for factor VIII-related antigen (FVIIIR:Ag), lymphatics from lo patients with malignant lymphoma or testicular carcinoma undergoing lymph-angiography were examined. After the lymphangiography was terminated, a part of the cannulated lymphatic vessel was removed and prepared for immunohistochemical examination for FVIIIR:Ag. All the lymphatic vessels showed positive cytoplasmatic staining for FVIIIR:Ag in the endothelial cells, the reaction being weak and patchy when compared with blood vessels. Electron microscopy was done on five lymphatic vessels and showed these to be lined with endothelial cells without a basal lamina.

Ventilatory effects of the pulse wave in the maxillary sinus.

The perostial ventilation of the human maxillary sinus is achieved via three main factors: diffusion, respiration wave and the mucosal pulse wave. The ventilatory factors have been studied with the help of a model sinus. The values used in the model are based upon in vivo human studies. Diffusion is responsible for the most important ventilatory effect in large ostia. Respiration has a ventilatory effect in all ostial sizes. The mucosal pulse has a ventilatory effect when the pulse volume exceeds the dead space of the ostium. When the ostial volume is diminished, the pulse-induced ventilation increases and keeps the total ventilation constant regardless of ostial size. In very small ostia, the mucosal pulse and respiration are the two important ventilatory factors.

Liver cell carcinoma in young women possibly induced by oral contraceptives.

Two cases of liver cell carcinoma in young women ingesting oral contraceptives have been found within a few months in the county of Vejle, Denmark. Including these two patients 22 cases of liver cell carcinoma in young women have been published since 1973, 19 of whom have used oral contraception. The possible effects of oral contraceptives in inducing liver tumors is discussed, and it is pointed out that no statistical proof of such an effect exists at present.

Benign and malignant epithelioid leiomyoma (leiomyoblastoma) of the stomach.

Epithelioid leiomyoma (Leiomyoblastoma) is a smooth-muscle tumour most often found in the stomach. On the basis of 5 new cases and a short review of the literature, clinical aspects and pathology concerning this neoplasm are described. It is emphasized that malignancy is difficult to predict according to morphologic criteria and therefore follow-up on these patients is essential.

Studies of the gas exchange and pressure in the maxillary sinuses in normal and infected humans.

The total gas pressure in experimentally occluded maxillary sinus was continuously recorded during 90 minutes on 7 healthy human subjects. PO2 and PCO2 were measured before and after the total pressure recording. In 3 cases the volume changes in the sinus were measured. The total gas pressure after an initial increase to about 35 mm H2O decreased to a steady state of about 70 mm H2O below atmospheric pressure. The volume changes in sinus showed a corresponding alteration. The gas measurements showed a decrease of PO2 of 25 mm Hg and a rise of PCO2 of 21 mm Hg. In 3 patients with acute purulent sinusitis there was seen a pressure of about 10 cm H2O above the atmospheric pressure.
