The first bone marrow transplantation took place in 1949 with studies that demonstrated the protection provided to the spleen of mice given a dose of irradiation that would otherwise be lethal. In 1960, studies in dogs provided important information about bone marrow transplantation in exogamic species, results that are applicable to humans. It was demon‐ strated that dogs could bear 2-3 times ...

BACKGROUND Inclusion of inhomogeneity corrections in intensity modulated small fields always makes conformal irradiation of lung tumor very complicated in accurate dose delivery. OBJECTIVE In the present study, the performance of five algorithms via Monte Carlo, Pencil Beam, Convolution, Fast Superposition and Superposition were evaluated in lung cancer Intensity Modulated Radiotherapy planni...

From 1990 to 1998, estimations of the effective dose from external and internal irradiation due to l 3 7 Cs and >,ACs were carried out for inhabitants in rural villages in theBryansk region, Russia, highly contaminated due to the Chernobyl accident in 1986. Yearly expeditions were conducted in autumn. The external effective dose was estimated from measurements with thermoluminescent (TL)dosemet...

Mammals can barely survive total-body ionizing irradiation greater than 10 Gy. To date, there are few drugs available for radioprotective therapy under such circumstances. Inosine, a natural derivative of adenosine, has been known to provide powerful protection for many kinds of cells and tissues against various insults both in vitro and in vivo. In the present study, we examined whether inosin...

Endocrine function was assessed in 31 children (17 boys) after fractionated total body irradiation used in the preparative regimen for bone marrow transplantation. Endocrine dysfunction was present in 25 children. Fifteen of 29 had growth hormone insufficiency 0.9-4.9 years after total body irradiation, yet only three of the 15 had received previous cranial irradiation. Five of 30 had thyroid d...

criteria and 40% in the best schedule (5-day intravenous). This compares favorably with prior experiences with decitabine and 5-azacitidine (CR rates, 6%-20%).4,5 Also, decitabine was less toxic than 5-azacitidine in relation to nausea/vomiting and local skin reactions (pain and induration in 5%-10% of patients on 5-azacitidine). The incidence of 65% of hospitalization is cumulative. As one del...

Two children developed papillary thyroid carcinoma after allogeneic bone marrow transplantation (BMT) probably due to radiotherapy during remission and pretransplantation conditioning. Establishing a relationship between the cellular thyroid stimulating hormone (TSH) effect and development of carcinoma in cases with high serum TSH concentrations is difficult. After BMT, patients should be regul...

Late effects of chemo-radiotherapy conditioning before bone marrow transplantation (BMT) are being increasingly recognised in long-term survivors, particularly children. They can be divided into two categories: those affecting hormonal status and those affecting specific organ function. All women treated develop ovarian failure with low levels of beta-oestradiol and raised values of follicle-st...

first was a staphylococcus albus infection which arose in a primary ventriculoatrial shunt inserted in a 60-year-old patient who had developed hydrocephalus in association with a cystic tumour of the posterior fossa. The second was an Escherichia coli infection which occurred after a revision of the upper end of a ventriculoperitoneal shunt in a 2-year-old child who had hydrocephalus caused by ...
