Radiation myelopathy.

Five cases of radiation myelopathy were found in a total of 10,000 cases given radiotherapy from 1968 to 1977. The clinical presentation and treatment details including the total dose, treatment volume, number of fractionations, overall time, and the RET value at the spinal cord were calculated and compared with other reports on this subject. The total number of fractionations ranged from 20 to 26 with an overall time of 32 days to 37 days. The dose received by four patients ranged from 1030 to 1900 RET, a little higher than the tolerance level of the spinal cord as compared to reported values. Two patients in this series had high blood pressure. The incidence of radiation myelopathy, already acceptably low, could possibly be reduced further by meticulous planning of radiation.

Nonsporing, anaerobic, gram-positive rods in saliva and the gingival crevice of humans.

Quantitative and qualitative examination of anaerobically isolated flora of the gingival crevice and saliva was carried out. It was found that half the organisms were anaerobes and that there were twice as many gram-positive organisms as there were gram-negative ones. Rods were predominant in the gingival crevice (60.5%) and cocci in saliva (69.1%). Of the total organisms, nonsporing, gram-positive anaerobic rods accounted for 24% in the gingival crevice and 9.7% in saliva. These organisms were characterized on the basis of the type of fatty acids produced from glucose and various biochemical reactions. They belonged to the following genera: Actinomyces, Propionibacterium, Arachnia, Lactobacillus, Eubacterium, and Bifidobacterium. Bifidobacteria were present only in saliva. Although members of the other genera were present both in the gingival crevice and saliva, there were considerable differences in the proportion of any particular organism (in relation to the total anaerobic viable count) between the two sites. The result of this study also indicates a greater than previously appreciated level of Propionibacterium and Arachnia in the human mouth.

Adenocysitc carcinoma of the uterine cervix: a clinicopathologic study.

Eight cases of adenocystic carcinoma of the uterine cervix, a rare histologic variant, are presented, with a brief review of 41 cases previously reported in the literature. They represent only 0.27% of 3254 cervical carcinomas that we encountered between 1962 and 1977. In all eight cases, there was early parametrial involvement, and the majority behaved aggressively. All eight patients were multiparas, and six of them were postmenopausal. Interestingly, including this series, 15 of 49 reported cases of this entity have been from India.
