RESUMEN

The tongue surface movement of young patients with or without open bite was evaluated by ultrasound images taken on the posterior part of the tongue on the frontal plane to determine whether there is any relationship between the tongue movement and open bite malocclusion in the early mixed dentition period. The standardized reproducible ultrasound images were obtained using ultrasound diagnostic equipment that was fabricated in a cephalostat unit having a probe stabilizer. At the central portion of the tongue, no significant differences were detected in the duration or the momentum of tongue surface movement on a frontal plane was detected between the patients with and without open bite during swallowing. The farther the region was from the central portion, however, the longer the duration and the bigger the momentum of the tongue surface movement was found in the open bite group. Based on this evidence, it is suggested that an open-bite child swallows by using a tongue thrust motion that forms using a large depressed area in the tongue, whereas a normal child without tongue thrust forms a rather narrow groove in the central portion of the tongue when swallowing.

RESUMEN

One-hundred-fifteen patients with cervical cancer were treated by placing bleomycin, carbazilquinone (Carboquone), and 5-fluorouracil suppositories in contact with cancer lesions located in the vaginal portion of the uterus or by inserting them into the cervical canal, twice a week, one to 14 times. The cancer lesions disappeared form 17 to 33 patients with Stage 0 lesions and 9 of 42 with Stage IA lesions. The remaining lesions were principally found in the deep portion of the cervical glands and tended to decrease the more often the suppositories were applied. This led to the presumption that if this local therapy had been carried on longer it would have eradicated even the remaining lesions from the patients with Stage 0 and IA lesions. The optimal per administration dose of bleomycin appeared to be 30 mg. The use of Witepsol (Dynamit Nobel Aktiengesellschaft, F.R.G.) suppository base was accompanied by frequent adverse reactions to it, which hindered the local therapy from being repeated over long periods of time. An equal amount mixture of hydroxypropyl cellulose and carbomer (Carbopol 934) as the suppository base was accompanied by relatively less adverse reactions, which permitted the prolonged local therapy with the suppositories. A trace of bleomycin was also found in the ovaries, but it did not cause microscopically evident histologic changes, nor did it affect the menstrual cycle. If early cancer can be treated completely by local therapy, it will be useful for the younger patient with early cervical cancer.
