Abstract
Renal insufficiency is a risk factor for osteoporosis and can increase risk of fracture. It may be a result of an age-related decline in renal function or chronic kidney disease. In patients with CKD, accurate diagnosis of osteoporosis or CKD-MBD is important for determining the most appropriate treatment. This was a cross sectional study was done at Institute of nuclear medicine and Allied Sciences, BSMMU, Dhaka from 1st January 2014 to 31st December 2014. Study population was total 69 postmenopausal women age over 50 years. Women with Bilateral hip replacement or bilateral hip pins or screws, metallic rods in spine, Carrying out BMD scan within the week after other radiological investigation using contrast media e.g. Barium meals or enema, IVPs were excluded from study. Clinical variables were- age (years), height (cm), weight (kg), BMI. Laboratory variables were- serum creatinine and BMD (Dexa). Estimated GFR was determined by using the serum Creatinine by MDRD formula. Renal function test and Bone mineral density (BMD) were done in all of these patients. Majority (43.4%) of the patients were in 6th decade. The mean weight was found 57.4±11.2kg. Majority 41(59.4%) patients belonged to T score at hip (-1 to -2.5) and their mean T score at hip was found (-1.1±1.1). Osteopenia and osteoporosis were found in 59.4% and 4.3% respectively according to BMD. High serum creatinine level was found in 10.1% cases. Renal function impairment was found in 79.6% of patient. Majority (50.7%) patients had mild decrease of eGFR (60-89 ml/min/1.73m²), There was Pearson's correlation (r=0.156; p=0.200) but not significant was found between age with T score at hip of the patients. Positive Pearson's correlation (r=0.112; p=0.361) was found but not significant between age and serum creatinine level. A significant negative Pearson's correlation (r= -0.274; p=0.023) was found between T score at hip and serum creatinine level of the patients. A significant negative Spearman correlation (r=-0.278; p=0.021) was found between BMD and serum creatinine of the patients. A significant positive Spearman correlation (r=0.580; p=0.001) was found between BMD and estimated GFR of the patients. This study was undertaken to evaluate the relationship between renal function and bone mineral density in postmenopausal women. Majority of the postmenopausal women were in 6th decade and most of them were overweight and obese. Renal function impairment was found in 79.6% of patient. Osteoporosis was found in 04.3% and 20.3% cases according to T score at hip and T score at lumber spine respectively. Significant negative Pearson's correlation was found between T score at hip and serum creatinine level of the patients. Significant negative Spearman correlation was found between BMD and serum creatinine of the patients. Significant positive Spearman correlation was found between BMD and estimated GFR of the patients.

Abstract
The chronic kidney disease (CKD) is associated with a variety of bone disorders and disorders of calcium and phosphorus metabolism. Bone disease associated with chronic kidney disease having higher rate of CKD progression and increased risk of death. To see the status of serum calcium, phosphate and intact parathyroid hormone in pre-dialysis CKD (stage- 3 to 5) patients. This was a across sectional study done in outpatient department of Nephrology of National Institute of Kidney Diseases and Urology, Dhaka, between 1st June 2012 to 31st May 2013. The patients of CKD stage 3, 4 and 5 yet not on dialysis attending out patients department of Nephrology, NIKDU by using MDRD-4 equation according to K/DOQI guidelines and reviewing previous medical records and investigation reports were enrolled in this study. There after serum calcium (corrected for serum albumin), phosphate and iPTH levels were measured and compared with the recommended target ranges in K/DOQI guideline. The number of patients with serum levels according to K/DOQI guidelines for different stages CKD(3,4,5) were as follows: serum calcium: 56.6, 58.5 and 76.7; serum phosphate: 55.2, 58.5 and 56.7; iPTH 37.9, 12.2 and 36.7 and Ca x P product 100.0, 97.6 and 86.7, respectively. The percentages of patients (who received drug) with serum calcium levels within according to K/DOQI guidelines for stages 3, 4 and 5 were as follows: serum calcium: 63.2%, 64.7% and 83.3%; respectively, serum phosphate: 63.2%, 61.8% and 66.7%; respectively, iPTH 42.1%, 14.7% and 4.7% and Ca x P product 100.0%, 100.0% and 87.5%, respectively. On the other hand patients who didn't receive drug the percentages of patients with serum calcium levels according to K/DOQI guidelines for CKD stages 3, 4 and 5 were as follows: serum calcium: 50.0%, 28.6% and 50.0%; respectively, serum phosphate: 40.0%, 42.9% and 16.7%; respectively, iPTH 30.0%, 14.7% and 16.7% and Ca x P product 100.0%, 85.7% and 83.3%, respectively. The patients achieving the four recommendations of K/DOQI guidelines was 4(13.8%) in stage-3, 3(7.3%) in stage-4 and 5(16.7%) in stage-5. More than half of the pre-dialysis patients of CKD were within target range of serum calcium and phosphate recommended in K/DOQI guideline and this proportion was more in those who were taking both phosphate binder and Vit-D. Ca x P was within target range in almost all patients so it may not be an important parameter for therapeutic decision making. However majority of the patients were out of target range of iPTH even though having normal serum calcium and phosphate level. So emphasis should be given in monitoring of iPTH level in early stages of CKD.

Abstract
Calcification of soft tissue and blood vessel wall occurs more frequently in dialyzed patients. The purpose of the present study was to estimate the risk of abdominal aortic calcification among end stage renal disease patients under maintenance haemodialysis. This case-control study was carried out in the Department of Nephrology at National Institute of Kidney Diseases and Urology (NIKDU), Dhaka and National Institute of Cardiovascular Disease and Hospital (NICVD), Dhaka, Bangladesh from January 2013 to December 2014 for a period of two (02) years. Chronic kidney disease in stage 5 {CKD-5(D)} patients older than 18 years on maintenance haemodialysis (MHD) for more than 3 months were selected as case group. And same age and sex non CKD patients were considered as control group. Serum calcium, serum albumin, serum phosphate and iPTH were estimated by semi-automated biochemistry analyzer from the Department of Biochemistry of NIKDU, Dhaka and NICVD, Dhaka. Plain X-ray abdomen in lateral view was performed for all patients. Total 100 patients were enrolled for this study of which 50 patients were in end stage renal disease (ESRD) group and the rest 50 patients were in non-CKD group. Abdominal aortic calcification on X ray was present in 22(44%) patients of ESRD group and 6(12%) patients of non CKD group of population. Mean±SD serum calcium (corrected) level was significantly high (p<0.001) in ESRD patients (9.79±0.87) compared to non CKD group of population (9.13±0.70). Mean±SD of serum phosphate level was significantly higher (p<0.001) in ESRD patients (5.71±0.96) compared to non CKD group of population (4.20±0.59). However, mean±SD iPTH level showed no significant difference between ESRD (25.33±51.98) and non CKD group of population (38.53±19.52), though iPTH level remain below the target level in ESRD group. Abdominal aortic calcification is significantly higher among ESRD subjects.

Abstract
Cardiac valve surgery is considered one of the most frequent surgical procedures in which AKI is a common & serious complication. Although serum creatinine is routinely used as a marker of renal function, it poorly reflects the immediate post operative period renal function. Within minutes to few hours after a renal insult, plasma neutrophil gelatinase associated lipocalin (pNGAL) is released. The aim of this study was to assess the superiority of pNGAL over serum creatinine in detecting AKI in early post operative period. This prospective observational study was carried out in the Department of Nephrology of National Institute of Kidney Diseases & Urology in collaboration with National Institute of Cardiovascular Diseases (NICVD) & Dhaka Shisu Hospital (DSH) from January 2015 to December 2016. Total 120 patients were selected from inpatient ward of cardiovascular surgery department. According to inclusion & exclusion criteria total 80 patients were included who was undergone cardiac valve surgery. Serum samples for pNGAL were collected from study population 6 hours after completion of surgery & stored at -80°C, serum samples were also collected for serum creatinine day before surgery, in 1st post operative day (POD1) & 2nd post operative day (POD2). Total 79 patients undergoing cardiac surgery, who met the inclusion & exclusion criteria, were consecutively included. There were 44 male (55.69%) and 35 female (40.31%) ranged from 15-60 years, with mean age of 36 years. pNGAL level in the blood of AKI patients (244.19±59.61ng/ml) 6 hours after completion of surgery was significantly higher from the non AKI patients (171.73±68.63ng/ml). A positive significant correlation was found between pNGAL 6 hours after completion of surgery & serum creatinine at POD1, POD2. This study demonstrated that level of pNGAL concentration 6 hours after completion of cardiac valve surgery increased before the rise of serum creatinine level & can thus AKI can be detected earlier by pNGAL.

Abstract
Isolated CABG (coronary artery bypass grafting) has the lowest incidence of AKI (Acute Kidney Injury), followed by valvular surgery and then, combined CABG with valvular surgery. Due to the difference in baseline characteristics and in surgery type, the range of incidence is between 8.9 and 39% based on RIFLE (Risk Injury failure loss end stage kidney disease) or AKIN (Acute Kidney Injury Network) criteria. The advent of novel biomarkers of kidney injury has opened a new era of early detection and prognosis prediction for AKI. NGAL is a small molecule of 178 amino acids that belongs to the super family of lipocalins, which are proteins specialized in binding and transporting small hydrophobic molecules. The expression of NGAL raises 1000 fold in humans and rodents in response to renal tubular injury and it appears so rapidly in the urine and serum that it is useful as an early biomarker of renal failure. The role of plasma NGAL to classify AKI severity and predict the need for RRT (renal replacement therapy) after cardiac surgery has been suggested. Although study subjects were more or less from same cohort (All undergone cardiac surgery), previous studies showed that NGAL raised differently in different proportion. NGAL as an early AKI marker has successfully passed through the pre-clinical, assay development and initial clinical testing stages. It is badly need to enter in a consensus about the cutoff value of NGAL which should help the physician about leveling a case as AKI or non AKI and their consequence management.

Abstract
In a series of 23 patients with surgically proven subdural hematoma of durations ranging between two days to seven months, the detection rate of Tc-99m-pertechnetate brain imaging was higher than computerized transaxial tomography (CT). With dynamic perfusion scanning, the detection rate was 71.5%. However, when combined with sequential static images obtained at 10 minutes, 2 hours and 3--4 hours, the detection rate rose to 92% regardless of the duration of the disease. In contrast, CT demonstrated the hematoma in 52% of the cases. In another 28% the diagnosis was suggested through nonconclusive evidence or presence of contralateral shift of midline structures. Lastly, the result of CT scanning was dependent on the size of the subdural hematoma as evaluated at the time of operation.

Abstract
The effect of aorto-coronary bypass graft surgery (CBG) upon regional myocardial perfusion (RMP) was studied in 23 patients using thallium-201 myocardial perfusing imaging after exercise. We compared the changes in RMP with the clinical status and ECG's during graded treadmill exercise (GTX) before and after CBG. After CBG, the New York Heart Association's "functional class" improved from 3.2 +/- 0.1 (mean +/- SE) to 1.2 +/- 0.2, p less than 0.005. The GTX performance of the patients was also significantly improved postoperatively as judged by the total exercise time (11.7 +/- 0.6 min postop, compared with 7.2 +/- 0.5 min preop; p less than 0.005). Postoperative improved Tl-201 scintigrams were observed in 19 patients, but in only nine patients did the perfusion distribution return to normal. Thus, Tl-201 exercise scintigrams following CBG demonstrate improved RMP in most patients. Failure of regional myocardial perfusion to improve postoperatively, however, does not preclude marked alleviation of angina and improved exercise tolerance.

Abstract
In order to cut down the time needed for the preparation of the thermally damaged erythrocytes, the effect of heat was combined with the use of a higher concentration of ACD. Heating of the 51Cr tagged red cells was performed in a water bath, at 50 degrees C for 15 minutes, in the presence of ACD in the ratio of one ml ACD for every 3 ml blood. Using this technique, the obtained splenic scans in 20 normal individuals were excellent in quality. In the posterior view, the spleen was oval with an oblique long axis in 65% of the cases and transverse long axis in another 15%. In the remaining 20% the spleen was globular. The average measurements of the spleen were 10.5 X 7,1 cm, with a circumference of 29.8 cm. By planimetry, the surface area of the spleen averaged (59 +/- 12.4) cm2 (Mean +/- 1 S.D.) In the lateral projection, the surface area of the splenic scan was larger by an average of 40% than the picture obtained through the posterior approach in all the six examined subjects.

Abstract
A method is presented for the simple, non-computerized analysis of the radiohippuran renogram by subtraction of the extrarenal radioactivity as monitored simultaneously by a detector centered over the manubrium sterni. This method requires the application of a calibration factor, relating the level of radioactivity recorded by the sternal detector to that over each kidney area at the end point of the phase of initial rise on each side separately. The results in 15 normal individuals showed a narrow range of values, indicating a high degree of resolution. Verification of the basis of this method of analysis was obtained by accounting for all of the counting rate as extrarenal sources in the tracings of nephrectomized subjects. A further advantage is that the tracing recorded by the sternal detector may be used to calculate renal blood flow.

Abstract
The study was carried out in Medicine and Pediatrics Department of Rajshahi Medical College Hospital, and Natore Sadar Hospital, both are located in the northern territory of Bangladesh. Period of study ranged from admission of patients till discharge. On 8th June 2008, 83 patients of Singra Upazilla Natore were admitted in Rajshahi Medical College Hospital and Natore Sadar Hospital with the history of consumption of Puffer fish. A presumptive diagnosis of Puffer fish poisoning was made on the basis of classical clinical presentations followed by Puffer fish ingestion. Blood and urine samples from 38 patients were sent to Frankfurt, Germany for toxicological analysis. The cases were clinically reviewed periodically and routine investigations were done. Report of the toxicological study confirmed the diagnosis of tetrodotoxin poisoning. Important neurological symptoms observed were peri-oral paresthesia (71), tingling over entire body (50), dizziness (35), headache (20). Muscular paralysis of the limbs was noted in 13 patients, of which 7 patients developed respiratory involvement. All the patients who developed respiratory involvement died. Early diagnosis and supportive management could ensure a safe and favorable outcome. Management of respiratory failure by ventilator support can be life saving. doi: 10.3329/taj.v21i2.3790 TAJ 2008; 21(2): 121-125
