This proposal aims to contribute to ongoing efforts by Member States in Africa to address the importance of Radiopharmacy in development of Good Radiopharmaceutical Practice in Nuclear Medicine and Departments and all institutions involved in the production, control, distribution and research of radiopharmaceuticals by promoting e-learning program in a combination of traditional teaching and practical work that provide effective, low cost educational opportunities to all professionals in a field of Radiopharmacy. The first component of the project will be to establish e-learning platform designed as an innovative learning apparatus that, working alongside conventional teaching methods, integrates education in all aspects of Rad...

METHODOLOGY Fourteen patients underwent planar immunoscintigraphy and/or tomoscintigraphy. RESULTS With tomography in comparison to planar scintigraphy, we can access better distinction of tumor and estimation of its size. Other imaging methods (computed tomography, ultrasonography) have an advantage in detection of liver metastases, while immunoscintigraphy is more specific for the assessment of malignant abdominal tumors and extrahepatic metastases. CONCLUSIONS The first results point out that Oncoscint CR-103 can be useful in diagnosis of recurrences and metastases of colorectal carcinoma, viability assessment after radiotherapy and in the choice of the adequate surgical treatment in dependence of the spread of the disease.

Thus, this study was aimed to analyze a possible impact of cigarette smoking on the effect of radioiodine therapy in the patients with Graves’ disease.The study included 31 patients (16 smokers and 15 non-smokers) with GD, aged from 22 to 73 years, who were treated with a single dose of iodine-131 sodium iodide (131I-NaI) and subjected to a 12-month follow-up, thereafter. Patients were treated with antithyroid drugs (ATDs) before RIT and described very intense stressful events occurring prior to diagnosing Graves’ hyperthyroidism. A successful response to RIT was defined as euthyroidism and subclinical or clinical hypothyroidism, while an unsuccessful response was defined as persistent hyperthyroidism.Comparison of age (47.4±9.41 vs. 49.5±13.8 years, p=0.628) at the time of RIT, applied activity of 131I-NaI...

Real-time, D-US and HRA were performed in 108 patients. In patients with portal venous aneurysm, hepatopetal blood flow was increased, while portal perfusion did not differ from controls. In portal hypertensive patients, D-US detected dilatation of the portal system veins, with decreased blood flow. In comparison to the portal perfusion in controls and portal venous aneurysm, values were significantly (p < 0.01) lower in chronic active hepatitis and liver cirrhosis and differed between themselves (p < 0.01). In the groups of cirrhotic patients with esophageal varices, sclerosed esophageal varices, recanalized umbilical vein, partial portal thrombosis and cavernous portal vein with hepatofugal, hyperkinetic or slow blood flow, ...

This retrospective study enrolled 82 children (30 girls and 52 boys aged between 2 months and 16 years; mean 5.8 +/- 4.5 years) with previously documented hydronephrosis or ureterohydronephrosis (42 left-sided, 28 right-sided and 12 bilateral). DRS "F-0" was started after intravenous administration of diethylene-triamine- pentaacetic acid (DTPA) mixed with furosemide. Results of DRS "F-0" were analyzed qualitatively (visual analysis of scintigrams and renography curves) and quantitatively (time to reach maximum of the kidney curve-T max, washout of the tracer-WO, the furosemide cleara...

The study was performed in 5 patients with IMACIS 1 containing the cocktail of 111MBq 131I MoAb 19-9 F(ab')2 and MoAb anti-CEA F(ab')2 and 8 patients with INDIMACIS 19-9 containing 150MBq of 111In-labeled MoAb 19-9 F(ab')2. With IMACIS 1, in all the patients, both tumor marker values were elevated. The number of TN was 3/5 and TP 2/5. From 2 TP, one had recurrence of the diseases with peritoneal carcinosis and one with liver metastases. In one patient, the results influenced the therapeutical management. With INDIMACIS 19-9, there were 2/8 TN, with borderline value of CEA and CA 19-9. TP were 6/8 (all with elevated tumor marker values, five of them many times; 3 with recurrences, 1 with recurrence and liver metastases and two with only liver metastases. In three p...

Urological symptoms (urgency, frequency and incontinence) are manifestations of uninhibited detrusor contractions. The goal of rehabilitation programs is to develop voluntary bladder control, to improve urologic symptoms and to increase bladder capacity. Bladder training, strategies to suppress urgency, electrical stimulations such are anogenital, transcutaneous and percutaneous electrical nerve stimulations have been used in the treatment.

MATERIALS AND METHODS: Fifty-nine consecutive asymptomatic patients (16 DM1, 43 DM2) underwent myocardial perfusion scintigraphy with 99mTc-sestamibi (MPS). They were evaluated for body mass index, metabolic control of DM, type of therapy, systemic arterial hypertension, dyslipidemia, nephropathy, retinopathy, peripheral neuropathy, smoking, and familial history of CAD. RESULTS: MPS was abnormal in 15 patients (25.4%): 12 (20.3%) with perfusion abnormalities, and 3 with isolated left ventricular dysfunction. The strongest predictors for abnormal myocardial perfusion were: age 60 years and above (p = 0.017; odds ratio [OR] = 6.0), peripheral neuropathy (p = 0.028; OR = 6.1), nephropathy (p = 0.031; OR = 5.6), and stress ECG positive for ischemia (p = 0.049; OR ...

Skin melanoma is one of the most malignant diseases with increasing incidence rate. Sentinel node biopsy (SNB) is very important for early detection of metastatic spread. The aim of the study was to analyze the first 40 patients with skin melanoma of 1 to 4 mm Breslow thickness when SNB was indicated. Methods. The patient characteristics, localization of the primary melanoma as well as histology grade were analyzed. SNB with intraoperative radiocolloid and methylene blue dye detection was performed. Results. Complication rate after SNB was analyzed and seroma was found in 5% of the patients. The therapeutic node dissection was performed in 10 patients with positive sentinel biopsy. The follow-up lasted two years. In five patients the false negative SNB was defined after the mean time of 11 months and the therapeutic dissection was performed. Conclusion. SNB in melanoma patients is a useful diagnostic procedure. It is advised for melanoma of 1 to 4 mm Breslow thickness.
