Quimioembolización selectiva con adriamicina-urografin-lipiodol, en el tratamiento del hepatocarcinoma / Embolization with adriamycin-urographin-lipiodol in patients with liver carcinoma

Various methods of regional chemotherapy have been used in patients with non ressectable hepatic carcinoma. We report our preliminary experience with embolization using adrimycin-urographin-lipiodol in 2 patients with this cancer in whom a considerable reduction of tumoral mass was observed. The pertinent literature is briefly commented

Effects on school children of prophylaxis of mothers with iodized oil in an area of iodine deficiency.

The results of tests of intellectual and psychomotor performance and school performance in a group of school children from a rural impoverished and iodine deficient Andean community whose mothers received injections of iodinated oil prior to the end of the first trimester of pregnancy have been compared with results in children from a neighboring comparable community whose mothers had received no iodinated oil. Subjects between ages 8 and 15 were studied. Statistically significant differences were not observed between the two groups in tests of intellectual function, but children of mothers who had received iodinated oil performed better on tests of psychomotor maturation. The group whose mothers had received oil performed distinctly better when assessed in terms of school drop-out rates, grades achieved, grades repeated, and in overall performance as judged by teacher notes in school records. Performance of both groups on standard tests of intellectual and psychomotor function was lower than standard scores. This may be a result of social and cultural deprivation, the general malnutrition prevailing in the region or other unidentified factors. The improved scoring and school performance exhibited by the children of mothers who received iodinated oil underlines the importance of prophylaxis with iodine in iodine deficient regions as one important contributor to community development.

Experiencia personal en el uso del lipiodol ultrafluido en las fístulas urogenitales iatrogénicas: nueva modalidad de tratamiento / Personal experience in the use of ultrafluid lipiodol in iatrogenic genitourinary fistulas: a new treatment modality

Apoyados en la propiedad que tiene el lipiodol de estimular la granulación de los tejidos, se utiliza con resultados exitosos en el tratamiento de las fístulas urogenitales, secuelas de accidentes quirúrgicos y obstétricos, lo cual queda corroborado por los casos curados mediante la instilación vesical del mismo. Con este nuevo procedimiento, se evita realizar una nueva intervención quirúrgica a estas pacientes con pocas posibilidades de curación mediante la cirugía

Estudo histomorfológico do tecido conjuntivo subcutâneo do rato ao implante de pastas à base de hidróxido de cálcio, contidas em tubos de dentina humana / Histomorphologic study of the subcutaneous connective tissue reactions of rat, due to the implantation of calcium hydroxide pastes contained in human dentin tubes

Foram utilizados 36 ratos, albinos, machos, adultos jovens, divididos em 3 grupos, de 12 animais cada, agrupados inicialmente em gaiolas para 3 indivíduos. Os animais receberam implantes de tubos de dentina humana contendo as seguintes pastas: Grupo I - Hidróxido de cálcio + Polietileno glicol 400; Grupo II - Hidróxido de cálcio + Lipiodol (ultrafluido) e Grupo III - Hidróxido de cálcio + Paramonoclorofenol canforado 2,5:7,5. Decorridos os períodos de 30, 60, 90 e 120 dias, os animais foram recuperados e as áreas circunjacentes aos implantes, removidas e preparadas para estudo histológico. Os resultados microscópicos mostraram que as misturas correspondentes aos Grupos I, II e III, comportaram-se como irritantes de tecido conjuntivo subcutâneo do rato, possibilitando no entanto cápsula em colagenizaçäo progressiva no decorrer dos períodos

Effect of iodized oil on iodine content, thyroglobulin maturation and on biochemical constituents of endemic goitre in brazil.

The biochemical and morphological changes in thyroid glands were studied in 5 patients with endemic goitre in the region before and one year after the administration of iodized oil. Each patient received a tracer dose of 125-I 3-5 weeks before the biopsy and another tracer of 131-I 12 h before surgery. It was observed that: 1. Iodine deficient goitrous glands had more protein per gram of tissue and that this was corrected by iodination. 2. The goitrous glands exhibited a higher relative proportion of particulate iodoprotein that incorporates more labelled iodine in relation to time of labelling. This abnormal situation is reverted to normal by iodination. 3. A significantly higher proportion of T3 + T4 is synthetized by the glands treated with iodized oil. 4. The increased amount of 127-I per gram of tissue is followed by an increased iodination level of thyroglobulin. 5. The ultracentrifugal pattern of proteins observed for iodine deficient glands differed from the iodinated glands, indicating a failure of maturation of thyroglobulin and possibly a greater than normal degree of heterogeneity. 6. The shift in sedimentation pattern was clearly induced by the increased degree of iodination, as shown by the iodized oil injection. 7. The increased cellularity and the higher rate of protein synthesis in the goitrous glands are reverted to normal after the iodized oil injection.

Prophylaxis and treatment of endemic goiter with iodized oil in rural Ecuador and Peru.

PIP: Endemic goiter is a health problem in many areas of the world; in some areas the disease is so severe that cretinism and other defects are found. In many areas geographic, economic, and other factors prevent the use of iodized salt as a preventive measure. Field studies were begun in 1966 to determine the feasibility and effectiveness of parenteral administration of iodized oil in goiter prevention. Studies were carried out in Ecuador and Peru. In Ecuador 2 villages were chosen in which the prevalence of goiter was about 60%; in Peru 3 villages were chosen where incidence was about 50%. Prevalence of goiter decreased for 20 months during the study but then began to rise again with the maximum reduction seen up to age 18 and minimal reduction after 40 years of age. The control groups in the study experienced only slight decreases in rate of incidence. Cretinism has not yet appeared among the progeny of the population injected with iodized oil but several instances have appeared in control groups. The use of iodized oil as a public health procedure for the prevention of endemic goiter and its associated defects is an acceptable measure in regions where salt iodization cannot be done.^ieng
