Two cases of nevoid basal cell carcinoma syndrome.

Two cases of nevoid basal cell carcinoma syndrome were reported with a review of pertinent literature. The first case was a 59-year-old man, whose autopsy was warranted. Signs and symptoms manifested in this case were basal cell carcinoma, generalized multiple nevi, multiple cysts in the jaws and long bones, pits in the palm and sole, frontal and occipital bossing, ossification of the falx cerebri, a bifid rib, renal fibroma and a patent foramen ovale. The family history revealed a hereditary predisposition as to the syndrome. The patient in the second case included basal cell carcinoma, multiple nevi, multiple jaw cysts, pits in the palm and sole, frontal bossing, calcification of the falx cerebri, cervical vertebral fusion and high-arched palate.

Regional cerebral blood flow alterations remote from the site of intracranial tumors.

Regional cerebral blood flow (rCBF) was investigated in 12 patients with brain tumors, using a 254-channel dynamic gamma camera. In nine of the 12 cases, hyperemic regions with loss of autoregulation were seen in sites remote from the tumor (the area around the tumor was in most cases also hyperemic). These remote rCBF abnormalities were found in the lower posterior part of the hemisphere in six cases, and in the frontal region in three. The location of the remote rCBF abnormality seemed to depend on the site of the tumor: cases with frontal and posterior fossa mass lesions had hyperemia in the lower part of the temporooccipital regions, cases with centroparietal mass lesions had hyperemia mostly in the frontal region. This may mean that the remote rCBF abnormality is due to local tissue compression against unyielding anatomical structures, namely, the tentorium and the falx. It is suggested that these abnormalities may constitute evidence of an early stage of a dangerous clinical condition: a state of preherniation.

I-cell disease (mucolipidosis 11). Pathological and biochemical studies of an autopsy case.

An autopsy case of I-cell disease was examined by histological, histochemical, ultrastructural and biochemical methods. Cultured fibroblasts contained numerous PAS- and oil-red O positive granules consistent with lysosomes. The beta-galactosidase activity was specifically low in liver of the patient. The fiboblast-like cells including the cardiac valves, periosteum and stromal cells of the organs were closely similar to those found in mucopolysaccharidoses histochemically as well as ultrastructurally. Lipid-like materials were observed massively in the myocardium and in the neurons of spinal ganglia, and from these organs excessive amount of ceramide tri-hexosides (CTH) was extracted. In a few hepatocytes the dense membrane-bound bodies suggestive of lipids were found by electron microscopy. Swollen glomerular epithelium contained strongly colloidal-iron positive material, but the amount of mucopolysaccharides in kidney was not elevated. In this paper, the relationship among the morphology, the material stored and the enzymes was discussed.

Morphological and biochemical studies of a case of mucopolysaccharidosis II (Hunter's syndrome).

An autopsy case of a 19-year-old boy who had shown typical gargoyle features, strictly consistent with mucopolysaccharidosis type II (Hunter's syndrome) was reported. Histologically, cytoplasmic vacuolar change was found in hepatocytes, sinusoidal epithelium of spleen, follicular cells of thyroid, Sertoli cells of testis, chromophobe cell of pituitary and generalized fibroblast-like cells including meninges, cardiac valve and periosteum. The vacuoles consisting of membrane-bound structures with flocculus protein-like material and occasional electron dense bodies on electron microscopy, were considered to be the site of mucopolysaccharide deposition by histochemical analysis. Deposition of lipid material consistent with so-called membranous cytoplasmic body was observed in the neurons of central, peripheral and autonomic nervous system. Hepatosplenomegaly could be explained by cytoplasmic deposition, but the cause of cardiomegaly remained further to be studied. Biochemically hepatic mucopolysaccharide was identified as heparan sulfate, while in the kidney dermatan sulfate and heparan sulfate were detected. The correlation between morphology and biochemistry, and between deposition and degeneration was discussed.

Ceftezole, a new cephalosporin C derivative I. In vitro and in vivo antimicrobial activity.

Ceftezole, a new cephalosporin antibiotic similar to cefazolin, has the following chemical structure: (6R,7R)-8-oxo-7[2-(1H-tetrazol-1-yl)acetamido]-3-[(1,3,4-thiadiazol-2-ylthio)methyl]-5-thia-1-azabicyclo[4.2.0]oct-2-ene-carboxylic acid. Ceftezole was found to be a broad-spectrum antibiotic, active in vitro against many species of gram-positive and gram-negative bacteria except Pseudomonas aeruginosa, Serratia marcescens and Proteus vulgaris. The activity of ceftezole against clinical isolates of Escherichia coli and Klebsiella spp. appeared to be nearly equal to that of cefazolin and higher than those of cephaloridine and cephalothin. Cross-resistance was observed between ampicillin and cephaloridine, but not between ampicillin and ceftezole, in susceptibility tests on clinical isolates of P. mirabilis. The in vitro activity was little affected by the inoculum size, the presence of human serum or the test medium. Ceftezole exhibited apparent bactericidal activity at the concentrations above the minimum inhibitory concentration (MIC) against both S. aureus and E. coli. The development in vitro of resistance by S. aureus 209p and E. coli NIHJ to ceftezole after 16 transfers was similar to or somewhat slower than that to other drugs tested. Ceftezole was relatively stable in nutrient broth and minimally degraded in the serum or tissue homogenates of rats. Ceftezole, in a single subcutaneous administration, exhibited somewhat less efficacy in mice against intraperitoneal infections with Streptococcus pyogenes, S. pneumoniae, E. coli, K. pneumoniae or P. mirabilis than either cephaloridine or cefazolin. However, ceftezole exhibited efficacy similar to that of cephaloridine or cefazolin when administered in three doses. Furthermore, ceftezole was as effective as cefazolin in the treatment of experimental abscesses in mice caused by subcutaneous inoculation with S. aureus.
