[The relationship between extracranial carotid atherosclerosis in an ultrasound study and periventricular hyperintensity in MR images].

We have evaluated the relationship between carotid atherosclerotic change and periventricular hyper intensity (PVH). PVH was studied in 66 cases with cerebral thrombosis, comparing them with another group of age-matched controls, which consisted of 29 cases with hypertension, diabetes, and hypercholesteremia. MRI (fluid attenuated inversion recovery) and B-mode carotid ultrasonography of each lesion were analyzed.

[Three times of anesthetic management in a patient with myotonic dystrophy].

A 38-year-old female, at 38-week gestation, was scheduled for cesarean section under epidural anesthesia. After the delivery, it was found that she had been diagnosed as myotonic dystrophy by the other physician and the neonate was a floppy infant indicating hereditary neuromuscular diseases. In her case, myotonic dystrophy had not been advanced and symptoms had been mild.

Potential use of beards for single-follicle micrografts: convenient follicle-harvesting technique using an injection needle.

The authors developed a convenient hair-harvesting procedure using a disposable 18-gauge injection needle, which is common in every clinical scene. The needle was used as a skin puncher to harvest single follicles. The harvested micrografts were transplanted without trimming any of the adjacent tissue around the follicle.

A model of acute subdural hematoma in the mouse.

The availability of genetically modified mice has allowed the study of genetic influences on acute brain injury. An animal model of acute subdural hematoma (ASDH) has been previously described in the rat but not the mouse. We describe a method for producing ASDH in the mouse.

[CT-pathologic correlation for the alveolar extension of pulmonary adenocarcinoma].

Alveolar extension of pulmonary adenocarcinoma is characteristically demonstrated as an area of ground-glass attenuation (GGA). We correlated the CT attenuation value of GGA with the aeration rate of the pathologic specimen measured with a high-resolution image analyzer (OLYMPUS). The CT values of GGA seen in fourteen adeno-carcinomas were measured for helical (slice thickness 10mm) and thin slice CT (slice thickness 1 or 2mm).
