[en] Neuroblastoma is the most common extracranial solid tumor of a childhood. Neuroblastoma is well known for its variability in clinical behavioral and distinct biological features. In a history of pediatric oncology it is a first disease, where the biological marker (NMYC amplification) was used for a prospective therapeutical randomisation. Current research is focused on detection of a new biological prognostic markers in neuroblastoma and implementation of a new therapeutical approaches into a clinical practise (eg. antiangiogenic therapies, metronomic chemotherapy, biotherapy, immunotherapy.

[en] This patent specification relates to a partially disposable shielded syringe for injecting radioactive material into a patient. It is claimed that the technique overcomes the problems of non-standardisation of syringe size. (U.K.)

[en] The Nuclear Medicine Department of the Philippine Heart Center has introduced the detection of coronary heart disease through myocardiac perfusion imaging. The cardiovascular procedures are availed of free-of-charge to registered PHCA patients excepting for the costly TI-201 imaging. In summary, coronary perfusion in imaging should be an integral part of coronary arteriography. Barring the expensive cost of TI-120, myocardial perfusion imaging is ideal for detection of coronary heart disease. Experience shows better sensitivity of TI-201 than exercise ECG for detection of ischemia. Another non-invasive procedure for the detection of acute infarction is the radionuclide imaging using a bone radiopharmaceutical Tc99m prophosphate. In conclusion, acute infarct imaging is a valuable adjunct to ECG and enzyme studies. (RTD)

[en] The metal protective sheath consists of an axially symmetrical cylinder with a ring with notches at the front. A single injection is accommodated in the longitudinal hole of the cylinder, where the wing shape on the injection tube can be completely accommodated in the notches. The injection is therefore fixed axially. (DG)

[en] Primary methods of radionuclidic standardization serve as the underlying basis of the physical measurement standards of activity that are needed in virtually every sub-discipline of radioanalytical and nuclear chemistry. Primary methods refer to the direct measurement of the number of nuclear transformations that occur per unit time, without recourse to other calibrations or standards. Such measurements, leading to the development and dissemination of radioactivity standards, are primarily performed under the purview of national metrology laboratories, like the National Institute of Standards and Technology (NIST) in the USA. This paper briefly reviews some of the various primary methods that have been developed by many such laboratories over many years. Their features and their role in ensuring the quality of radioactivity measurements are highlighted by several primary standardizations that have been recently performed at NIST. (author)

[en] Full text: After giving first dose of radionuclide pain palliation therapy in 20 patients, re-therapy was considered again in these patients. 2nd therapy was done in 20 patients followed by 3rd therapy in 11 of them which was subsequently followed by 4th therapy in 4 patients (total 35 re-therapy doses). Phosphorus-32 was used in a mean dose 6.15 mCi (4.5-7 mCi) in 15 pts. and Samarium-153, 60 mCi (45-95 mCi) in 20 therapies. Strict follow up data was available in all patients. Mean follow up duration was 13.75 months (6 month - 20 months). Re-therapy was done after an interval of 4.7 months on an average. Pre-treatment pain score and narcotic score were 6.8 and 3.5. Average Hemoglobin, white blood cell and platelet count was 11.2, 8,600 and 1,89,000 respectively. After administration of radionuclide therapy there was a predictive but fully recovered fall in platelet counts only. It decreased to a mean 1,63,000 at around 4-5 weeks. Post-treatment pain score and narcotic score were 4.1 and 2.5 (P<0.005 as compared with pretreatment level). No serious toxicity was noted in any patient. Radionuclide pain palliation remains a very safe and effective option. Retherapy can be done very easily will equally good effects. No hematological toxicity was seen in any of the patient
