Severe anaemia: its CT findings in the cardiovascular system.

Computed tomography of the upper abdomen and of the heart was performed in 21 patients with severe anemia (mean haematocrit value 0.23, mean haemoglobin content 39.6%). Gross morphology of the heart and great vessels (wall thickness, size of the chambers, lumina and walls of the vessels) were visualized in all patients without the use of contrast media. The smallest discernible difference between the normal heart muscle and blood filling its cavities was about 6-8 H and the smallest discernible difference between the aorta and the aortic blood was about 8-10 H (window width 150 H, window level 50 H). There were no CT signs of haemochromatosis of the heart, while CT measurements were highly suggestive of liver haemochromatosis in several cases. Visual evaluation of liver density in comparison to the density of blood in hepatic and portal vessels is misleading.

A CT evaluation of the intraperitoneal fluid distribution.

The intraperitoneal distribution of fluid and its detectability with a CT scanning were investigated in 13 patients during infusion of dialysate for peritoneal dialysis. An ascending pattern of spread i.e. from the lesser pelvis through the inframesocolic compartment to the supramesocolic compartment prevailed. Accumulation of fluid in the perihepatic space and in Morison's pouch as a function of fluid volume is at best approximated by a parabolic curve. Fifty to two hundred fifty ml. of fluid were detectable with a CT scanning in supine position in the majority of cases within the perihepatic space and Morison's pouch. The lowest amount of fluid detectable in the peritoneal cavity--25 ml. was found between the anterior abdominal wall and bowel loops in right decubitus.

Abnormalities of tooth development in pituitary dwarfism.

Roentgenographic studies of the jaws and teeth in a group of forty-eight pituitary dwarfs showed the following abnormalities in the development of the teeth: 1. Delayed shedding of the deciduous teeth. 2. Absence of resorption of the roots of the deciduous teeth at the usual time. 3. Marked delay in eruption of the permanent teeth. 4. Retention of permanent teeth in the maxillary and mandibular shafts. 5. Development of the apical parts of roots of the retained permanent teeth and their growth toward the lower mandibular edge. 6. Displacement of the first molars from the mandibular shaft to rami. 7. Tilting of some of the retained teeth. 8. Small size of the maxilla and mandible with overcrowding of the teeth in these bones. 9. Complete absence of buds of the wisdom teeth, even in patients in the fourth decade of life. 10. Stimulation of development and eruption of the teeth after administration of anabolic drugs. These abnormalities when present in combination depend on growth hormone deficiency since they do not occur in other types of dwarfism.

[Comparative intravenous and cholangiographic infusion studies in chronic diseases of the bile ducts].

Compared with the intravenous cholangiography the infusion cholangiography is the more effective and unambiguous investigation method of the gallbladder and the bile ducts. It considerably enlarges the diagnostic possibilities in the area of the bile ducts. A serum bilirubin level of more than 2 mg/100 ml allows positive cholangiograms by means of the infusion method, but is nearly always the cause for negative findings in intravenous application. In a hypalbuminaemia lower than 3 g/100 ml, in an increase of the alkaline serum phosphatase, of the serum transaminase and a pathological retention of bromsulphalein the bile ducts cannot be demonstrated also in the infusion cholangiography. A 20% glucose solution is sufficient as solvent in the infusion cholangiography. In the negative case the cholecystography and the intravenous cholangiography may be supplemented and enlarged by application of the infusion cholangiography as a more evident method of X-ray examination.

Abnormal basal angle of the skull in sex chromosome aberrations.

The basal angle was measured on skull films in 252 patients with hormonal disorders and sex chromosome aberrations. In cases of hormonal disturbance the basal angle was normal. In patients with Turner's syndrome (45,X chromosomes) the basal angle was enlarged while in patients with Klinefelter's syndrome (47,XXY chromosomes) and in those with extra X or Y chromosomes it was definitely reduced. A close relationship exists between the sex chromosome number and the size of the basal angle.

Radiological features of the skull in Klinefelter's syndrome and male hypogonadism.

Skull radiographs were performed in 21 cases of Klinefelter's syndrome and in 30 cases of eunuchoidism. The radiographic changes of the skull in Klinefelter's syndrome are: temporal flattening, decreased width of the vault, narrowing of the mandible, decreased length of the skull, shortening of the anterior fossa cranii, decrease in the angle of the base, thinning of the vault bones at the major fontanelle, premature and excessive calcification of the coronal suture, deepening of the posterior fossa and shortening of the mandibular rami. In hypogonadotropic eunuchoidism the skull radiographs show: small mastoid processes, fine bones of the vault, small sella turcica, club-shaped clinoid processes, excessive development of sphenoidal sinuses and in the fourth and later decades of life a diminished bone density (osteoporosis).

The skull in gonadal dysgenesis. A roentgenometric study.

Skull radiographs of 54 patients with Turner's syndrome have been studied. The following characteristic findings were frequently noted: mastoid processes of definitely decreased dimensions, small facial bones which were proportional to the stunted growth of the patients, enlargement and increased thickness of the mandible, extensive calcification of the petro-clinoid ligaments, excessive pneumatisation of the paranasal sinuses and increased angle of the base of the skull.
