[A pregnancy without detectable human placental lactogen (hPL)].

During a pregnancy of a 35 year old woman, we could not detect HPL in the peripheral serum, whereas other hormones showed normal values. Fetal growth ceased in the 36th week and a live neonate was delivered by caesarean section. The histological findings of the placenta and the perinatal record were not so unusual that they could account for the absence of HPL. This case illustrates that fetal growth is possible without HPL-production.

A strumal carcinoid primary in the ovary.

A primary ovarian carcinoid tumour of insular strumal type in a 78-yr-old patient is reported. Strumal carcinoid of the ovary is a rare tumor of germ cell origin characterized by an intimate mixture of thyroid tissue and carcinoid. Correct diagnosis depends on a pathologic examination with the use of special stains. Because of its benign character, the treatment is primarily a surgical one and consists of a simple oophorectomy or salpingo-oophorectomy.

A scanning electron microscopic study of microvascular anastomoses on irradiated vessels: short-term effect of irradiation.

Experiments were carried out to determine the effect of previous irradiation on microvascular arterial anastomoses. The study focused on regeneration of endothelial cells and thrombus formation. Careful examination with scanning electron microscopy (SEM) showed a difference between irradiated animals and a control group. In the irradiated group one can notice a decreased regeneration, a greater amount of fibrin and platelets, and a higher incidence of microthrombi.

Model of elasticity of the human lung.

A model of the elasticity of the human lung has been developed to evaluate the relative importance of the characteristics of the lung parenchyma, of thorax configuration, and of gravity on the vertical gradients of pleural pressure and regional volumes, and on the linear displacements of lung tissue, of various lung volumes. The predictions of the model are compared with available experimental data. It is suggested that the bulk elasticity modulus of the human lung is high with respect to that of canine lungs, that the shearing forces are low ("effective" Poison's ratio of about 0.4-0.45), and that the variations of regional pleural pressures and volumes during deflation are determined primarily by the interaction between lung weight and changes in thorax configuration.

[Aplasia cutis congenita].

Aplasia cutis congenita is a rare disease with circumscribed absence of the dermis and the subcutis. Genetic constitution is a predisposing factor; the disease has a variable expressivity. The lesions show spontaneous healing after several months; corrective surgery is seldom indicated. The prognosis is good.
