Rare Coexistence Of Benign Renal Oncocytoma And Renal Cell Carcinoma
The coexistence of two tumors in a single person is not common. Finding two tumors in a single organ is rare. We are reporting a 65 years old male who presented with a long history of left loin pain. Clinical examination was unremarkable apart from hypertension. The histopathology of intraabdominal
mass seen on exploration of abdomen revealed oncocytoma and renal cell carcinoma.. Keywords: contralateral, nephrectomy, multifocality, hematuria, perinephric. Sudan Journal of Medical Sciences Vol. 3 (2) 2008: pp. 167-17

Caspian Sea level fluctuation and determination of setback line
In the past 25 years, rising of the Caspian Sea level, part of a natural treat to the sea, has inundated and destroyed many buildings and arable lands and threatened many inhabitations in coastal areas. The main reason for these damages is that the law-setback has lost its efficiency and human activities have proceeded seaward. The goal of this study is to introduce a proper setback line for the southern coast of Caspian Sea on the basis of critical water elevation and the results of coastal vulnerability assessment to sea level rise. This setback contains vertical and horizontal buffers. The Coastal vulnerability index (CVI) method is used for coastal vulnerability assessment and is also used in the Geographic Information System. Five variables in two sub-indices were used in this method. The final map obtained from coastal vulnerability assessment divided the coastal zone into low, moderate, high and very high risk categories based on quartile ranges and visual inspection of data. A mean distance of very high risk category of vulnerability map from a second vertical buffer in each rural district was then proposed as a width of horizontal buffer in the same rural district
Doctor-Patient Communication A Requisite for Better Medication History Taking: Insight from Sudan
Despite the awareness of doctors about the significance of obtaining a comprehensive medication history for patients, they often neglect this in their practice, resulting in an incomplete patient medication list. The study aimed to investigate the role of communication skills as a crucial part of optimal pharmacotherapy. An observational, cross-sectional study was carried out at internal medicine department in a tertiary hospital, Wad Medani, Sudan. The research instrument was a form involved a checklist rating a doctor’s performance during the medical encounters. Among 94 medical doctors, 51% were males and 6.15 (SE) was the average years of experience. About 13% of participants received under-graduation training in communication skills, while 21% had it after post-graduation. Concerning communication skills evaluation, 61% of specialists, 29% of registrars, and 7% of house officers reported an excellent performance. Gender and doctors’ ranking in a medical team had a significant role in communication skills (P-value <0.05) with an overall adjusted R2 of 0.339. Specialists were the most knowledgeable and skillful in obtaining structured medication history; 67% reported an excellent performance. Communication skills had a remarkable impact in getting patient medication history (P-value: <0.05) with an overall adjusted R2 of 0. 763.The study concluded that; gender and doctors’ ranking in the medical team were the main predictors for doctors to be a good communicator. Communication skills have a significant role in medication history taking. There was a gap in knowledge and training in communication skills among internal medicine doctors specifically, “house officers.” This gap negatively contributed to obtaining a comprehensive patient medication history
Comparative Analysis of Natural Radioactivity Content in Tiles made in Nigeria and Imported Tiles from China
In this investigation, natural radioactive contents in tiles manufactured in Nigeria and tiles imported
from China were measured using gamma ray spectroscopy. High Purity Germanium detector was
used to estimate the concentrations of some radioisotopes present in 17 samples of various tiles from
Nigeria and China. The average activity concentrations of 226Ra, 232Th, and 40K for the tiles were found
to be 68.2 ± 0.5; 173.9 ± 9.2 and 490 ± 15 Bq/kg and 58.2 ± 0.5, 161.5 ± 9.4 and 455.7 ± 15.1 Bq/kg for
the tiles from Nigeria and China respectively. Radiological hazard indices such as absorbed dose rate,
radium equivalent activity, external Hazard Index (Hex), internal Hazard Index (Hin), Annual Effective
Dose (mSv/y), Gamma activity Index (Iγ) and Alpha Index (Iα) were determined for both kind of tiles
from Nigeria and China. The mean values obtained were: 354.56 and 317.16 Bq/kg; 169.22 nGyh−1 and
153.92 nGyh−1; 0.95 and 0.87; 1.14 and 1.08; 1.59 mSv/y and 1.52 mSv/y; 1 and 1.15 and; 0.34 and
0.29 respectively. The mean value of radium equivalent obtained in this study is less than that of the
international reference value of 370 Bq/kg for the both kind of tiles

Assessment of natural radionuclides and its radiological hazards from tiles made in Nigeria
Activity concentration of 10 different brands of tiles made in Nigeria were analyzed using High purity
Germanium gamma detector and its hazard indices such as absorbed dose rate, radium equivalent activity,
external Hazard Index (Hex), internal Hazard Index (Hin), Annual Effective Dose (mSv/y), Gamma activity Index
(Iγ) and Alpha Index (Iα) were determined. The result showed that the average activity concentrations of
radionuclides (226Ra, 232Th and 40K) content are within the recommended limit. The average radium equivalent
is within the recommended limit of 370 Bq/kg. The result obtained further showed that the mean values for the
absorbed dose rate (D), external and internal hazard index, the annual effective dose (AEDR) equivalent, gamma
activity index and Alpha Index were: 169.22 nGyh−1, 0.95 and 1.14, 1.59 mSv/y, 1.00 Sv yr−1 and 0.34 respectively.
The result established that radiological hazards such as absorbed dose rate, internal hazard, annual
effective dose rate, gamma activity index and Alpha Index for some samples are found to be slightly close or
above international recommended values. The result for the present study was compared with tiles sample from
others countries, it was observed that the concentration of tiles made in Nigeria and other countries are closer,
however recommends proper radiation monitoring for some tiles made in Nigeria before usage due to the long
term health effec
