Estimates of dose to the bladder during direct radionuclide cystography: concise communication.

We estimate the absorbed dose to the bladder walls, Db, due to [99mTc]pertechnetate direct radionuclide cystography, with due consideration to the dynamic nature of the examination. Our analytical method resulted in Db values expressed as functions of the bladder filling time. These values are compared with published data based on a static bladder model. It is shown that the Db value depends strongly on the protocol under which the examination is carried out. It is also shown that the normal saline flow rate and the time of the administration of the radioactive material can be adjusted so that the radiation burden may be greatly reduced.

Effective RES blood flow changes in children with homozygous beta-thalassemia in relation to blood transfusion.

Denatured radioiodinated human serum albumin (DHA) clearance studies at a dose of 1 mg/kg body wt., were carried out in 16 thalassemic children, prior to and 7-10 days following blood transfusion, to investigate changes of the effective RES blood flow which might accompany the posttransfusion spleen size diminution. A statistically significant increase (P less than 0.001) of the DHA plasma clearance rate was observed 7-10 days following blood transfusion denoting an increase of the blood flow to the effective RES while at the same time the spleen diminished in size. It is suggested that changes in the effective RES blood flow in these patients are directly related to changes in the intrasplenic circulatory capacity.

[Treatment of denture stomatitis by the use of tissue conditioning].

In this paper, the efficacy of tissue conditioning treating stomatitis caused by dentures, was examined. It was found that 96.6% of the cases treated by this method were cured and the highest curative result was noted after a fifteen days period. Sex did not affect the curative result. The persistence of using tissue conditioning, for a period longer than four weeks, is in vain.

[Geriatric dentistry introduction].

The increasing number of old people in today's society is a reality. They are a group, whose special needs and medical problems are dealt in Geriatrics. Geriatric dentistry is the branch of Dentistry concerned with their dentical problems. In this article we discuss some of these special problems as an attempt to make this subject more comprehensible to the general practionner.

[Denture cleansing and denture stomatitis. Clinical investigation].

Three hundred patients with complete dentures were examined, to find out if there exists a relationship between denture cleansing and denture stomatitis prevalence. The study revealed that: 1. Denture stomatitis prevalence was 46%. 2. Mechanical means for denture cleansing were used by 84.67% of all patients, chemical means for denture cleansing were used by 5.33% and a combination of mechanical and chemical means by 10%. 3. Dentures with satisfactory cleanliness were used by 50.33% of the whole sample of patients and dentures with unsatisfactory cleanliness by 49.67% of all patients. 4. There exists a strong significant relationship (p less than 0.001) between dentures with unsatisfactory cleanliness and denture stomatitis prevalence. 5. There exists no significant relationship (p less than 0.05) between methods for denture cleansing and denture stomatitis prevalence.
