Positional distribution of fatty acids in glycerophosphatides of bovine gray matter.

Glycerophosphatides were isolated from ox brain gray matter by column chromatography. The fatty acid compositions of ethanolamine glycerophosphatides (EGP), serine glycerophosphatides (SGP), and choline glycerophosphatides (CGP) were determined by gas-liquid chromatography. The positional distribution of fatty acids in these glycerophosphatides were determined by phospholipase A hydrolysis (Habu habu venom). C(20) and C(22) polyunsaturated acids were confined almost exclusively to the 2-position of these lipids, where they comprised the majority of 2-substituents in EGP and SGP (oleic acid predominated in this position in CGP). In the 1-position, palmitoyl was the major substituent in CGP, stearoyl in SGP, and stearoyl or the corresponding alk-1-enyl group in EGP.

Xeroderma pigmentosum with versive seizures.

A boy with group A xeroderma pigmentosum and a series of progressive neurologic complications developed versive seizures at 8 years of age. Electroencephalography at 6 years of age revealed no epileptic changes or focal abnormalities. He was seizure-free until versive seizures developed; electroencephalography revealed frequent spike discharges in the right central and temporal regions. Neurologic complications and electroencephalographic abnormalities of 34 patients with group A xeroderma pigmentosum also were assessed. Only 3 patients with xeroderma pigmentosum have been reported to have a seizure disorder. This patient is the fourth reported with group A xeroderma pigmentosum associated with a convulsive disorder. Although neurologic manifestations in group A xeroderma pigmentosum are progressive and severe, it is unknown why so few of these patients develop seizure disorders.

Aicardi syndrome associated with an embryonal carcinoma.

A Japanese girl is reported who had the typical clinical features of Aicardi syndrome associated with embryonal carcinoma. She developed infantile spasms at approximately 4 weeks of age; her seizures were intractable in spite of treatment with numerous antiepileptic drugs and ACTH. At 22 months of age, her left cheek gradually became swollen. Laboratory findings were normal except for a marked increase in serum alpha-fetoprotein. A transoral biopsy of the tumor revealed an embryonal carcinoma. This patient is the first reported with Aicardi syndrome and embryonal carcinoma. The relationship between congenital malformations and neoplasms is discussed.

Internal carotid arterial blood flow velocity in infants.

The differences in the velocity and pulsatility indexes in the internal carotid artery were evaluated in 62 normal controls, 42 infants with cerebral palsy, and 22 infants with mental retardation, all within the first year of life. In the normal controls, the average maximal blood flow velocity (A/L), and the maximal end-diastolic flow velocity increased during the first year of life. Pulsatility index decreased significantly between the ages of newborn to 2 mos and 3-5 mos, and remained constant thereafter. Compared with normal controls, the average maximal blood flow velocity and the maximal end-diastolic flow velocity values were significantly reduced in infants with cerebral palsy during the first 6 months of life, while no differences in these values were observed in infants with mental retardation. There were no differences in the pulsatility index values in the 3 subject groups throughout the first year of life. Flow velocity in the internal carotid artery could reflect the status of the cerebral circulation in infants within the first year of life.

"Crazy paving appearance" on high resolution CT in various diseases.

PURPOSE: The purpose of this work was to demonstrate the variety of causes of crazy-paving appearance (CPA) on high resolution CT (HRCT). METHOD: To identify cases exhibiting CPA (ground-glass opacity with superimposed interlobular septal thickening and intralobular interstitial thickening) on HRCT, we prospectively searched for them over a period of 29 months. RESULTS: We identified 10 cases of CPA on HRCT, including 4 Pneumocystis carinii pneumonia, 1 alveolar proteinosis, 1 usual interstitial pneumonia, 1 pulmonary hemorrhage, 1 acute radiation pneumonitis, 1 adult respiratory distress syndrome, and 1 drug-induced pneumonitis. CONCLUSION: CPA can result from a variety of diseases. When we encounter CPA on HRCT, clinical information is necessary for differentiation of these entities.

Nonfunctioning adrenal rest tumor of the liver: radiologic appearance.

We describe the radiologic features of an adrenal rest tumor of the liver. The adrenal rest tumor appeared on ultrasound as a round, well defined, heterogeneous, solid mass in the posterior aspect of the liver, on angiography as a homogeneous hypervascular mass, and on dynamic CT as a mass containing components of both fat density and soft tissue density and showing early fill-in and early fill-out. Adrenal rest tumors should be included in the lists of hypervascular or fat-containing masses in the liver.
