Introduction: Posterior urethral valve (PUV) is the most frequent cause of urethral obstruction in male child. These lesions usually result in lifelong disabilities with incontinence and decreased renal function despite optimal medical management. Primary fulguration without upper tract diversion is the preferred modality of treatment in most cases of PUV. Regular follow-up is needed to check completion of valve fulguration, renal function, status of hydronephrosis, vesicoureteric reflux (VUR), urinary tract infection (UTI), and bladder function.Materials and methods: We conducted interventional study among 30 purposively selected patients of PUV in the Department of Pediatric surgery, Dhaka Medical College Hospital (DMCH), Dhaka, over a period of 20 months from December 2009 to July 2011. Age of study subjects varied from 2 days to 14 years. Among the 30 patients, 16 were children in the age group between 1year to14 years (53.3%), 11(36.7%) were infants and the rest 03(10%) were neonates. Most of the patients presented with weak urinary stream, dribbling of urine, straining at micturition, UTI and palpable bladder. All children were subjected to ultrasonography (USG), blood urea, serum creatinine, routine urine examination and culture studies. Structured questionnaire was used to collect information regarding improvement or disappearance of VUR and renal functional status before & after primary fulguration of PUV.Results: Average serum creatinine level was found gradually decreased in subsequent follow up in comparison with the previous one. This difference of creatinine level was found statistically significant in t-test (p<0.01). Average blood urea nitrogen (BUN) was also decreased which was found statistically significant (p<0.05). VUR was present in 63.3% cases. Non- VUR was found in 60% cases on right side and 50% cases on left side. On the third follow-up after 3 months it became 73.3% on right side and 63.3% on left side. Positive correlation found in Pearson correlation test about the changes of reflux grades before and after fulguration was significant at the level of 0.01(p<0.001). It was significant on both left and right kidneys. Positive correlation found in Pearson correlation test about the changes of GFR before and after fulguration was also significant at the level of 0.01(p <0.001). Collected data was cleaned, edited and analyzed with the help of software SPSS window version 15.0.Conclusion: In this study, VUR disappeared in some cases and decreased in majority of the cases by 3 months after adequate restoration of urethral patency. Renal function came to normal range in two thirds of the cases.J. Paediatr. Surg. Bangladesh 3(2): 71-77, 2012 (July)

Introduction: Congenital obstruction of the urethra is one of the most devastating anomalies to occur in the urinary tract and one of the few that are life-threatening in the neonatal period. Posterior urethral valve (PUV) is the most frequent cause of urethral obstruction in male child. These lesions usually result in lifelong disabilities with incontinence and decreased renal function despite optimal medical management. Primary fulguration without upper tract diversion is the preferred modality of treatment in most cases of PUV.

It was researched on the application of Anoda Heel Effect (AHE) with a step wedge on the effect of Signal To Noise Ratio (SNR) on Computed Radiography (CR) has been carried out. This research was conducted on a 21 step wedge with two treatments, namely the application of AHE and without the application of AHE. This measurement is repeated three times on radiographs to obtain a total image of six images (without the application of AHE as many as three images and with the application of AHE as many as three images). The results of taking radiographs using AHE and without AHE were measured using the RadiAnt Dicom Viewer program. The SNR value on the step wedge image without the AHE application has an average of 26.89. The SNR value on the step wedge image using AHE is 60.54. The results of the correlation test (Pearson correlation test) on the SNR showed that there was a significant and very strong effect of the application of AHE on the step wedge on the SNR in CR (p-value <0.001 and the R-value ranging from 0.600 to 0.799).

ABSTRACTStress can be perceived as a response to threats situations (either physical or psychological) caused by individual inability  to overcome existing threats within his/her environment. Job stress is the result of interaction between an individual (i.e. a worker) and his/her occupation. The objective of this study to identify the factor affecting tojob stress by the divers at PT. X. This study applied cross-sectional design conducted by observing the divers at PT. X. The population of this study was all divers working at PT. X. Data was analyzed by Spearman Correlation Test, Pearson Correlation Test, and Chi-square Test. The results of this study is strong correlation between personality type and job stress (as indicated by correlation coefficient 0.645). The divers’ age (correlation coefficient -0.283), educational level (correlation coefficient -0.220), years of service/experience (correlation coefficient -0.158), length of diving session (correlation coefficient 0.083), and threats of marine animal attack (correlation coefficient 0.156) had lower correlation with job stress. While the divers residence might also affect their job stress (as indicated by correlation coefficient 0.539).Keywords: job stress, diver

Abstract Background and Aims Serum creatinine is the most used biomarker of renal function in clinical practice. However, the correlation between creatinine and measured GFR is poor with a variability as wide as 200%. The causes of this phenomena are not clear. Some studies observed tubular handling (reabsorption and secretion) as well as intestinal secretion of creatinine, and depends of nutritional status . Importantly, these changes increased with the loss of renal function, masking changes in the evolution of real renal function. However, scarce evidence is available about the reliability of creatinine in reflecting the changes of renal function over the time in predialysis patients, compared to measured GFR. This information is relevant in the setting of clinical decisions. Method Spanish unicenter study developed at the Hospital Universitario de Canarias (Tenerife). In the pre-dialysis outpatient clinic, subjects are followed with measured GFR (clearance of iohexol by DBS). Measured GFR is performed at baseline and repeated as suggested by the clinical evolution. For this study we included all patients with repeated determinations of creatinine and measured GFR. The changes of creatinine in terms of increase (&gt;10%), decrease (&lt;10%) and stability (±10%) were compared with the changes in measured GFR. Results 89 cases with repeated measurement of GFR and creatinine were evaluated. In 61 cases (68.53%) discrepancies between changes in creatinine and measured GFR were evident. Graphic 1 shows differents discordancing cases with 39 cases (43.8%) overestimation, 7 (7.8%) of infraestimation and 15 cases (24.7%) not change of mGFR with changes on Cr. Conclusion Changes in creatinine do not reflect real changes in real renal function in about 70% of the cases. Whenever possible, the measurement of GFR by whichever method available should be considered in the renal care and follow-up of these patients.

ABSTRACT Clearances of inulin and para-aminohippurate (PAH) were studied before as well as three to nine years (average 5½) after surgery in 35 cases of primary hyperparathyroidism. The preoperative inulin clearance ranged from 18 to 105 (average 67) and the PAH clearance from 61 to 666 (349) ml/min/1.73 m2 BSA. In the follow-up studies clearances of inulin and PAH were, on the whole, well maintained both in subjects with normal as well as in cases showing depressed clearance values before surgery. In fact, a slight but statistically significant increase of inulin clearance was demonstrated in the material as a whole, whereas no significant change occurred in PAH clearance. The renal concentrating capacity was estimated before and after operation in 22 of the patients. An increase was almost regularly observed postoperatively but the concentrating capacity remained subnormal in almost half of the subjects studied. The changes in the concentrating capacity and clearances of inulin and PAH did not always run parallel. The renal clearance of phosphate was studied simultaneously with inulin and PAH clearances. Phosphate clearance decreased after surgery concomitantly with an elevation of serum phosphorus. However, restoration to the normal was not always obtained. Arterial hypertension was present in 40 per cent of the patients before and/or after surgery. Only grade I-II eye ground changes were found. Blood pressure was easily controlled by hypotensive drugs. A spontaneous disappearance or a decrease in the number of kidney stones was demonstrated radiologically at the follow-up studies in almost half of the patients. In only two subjects were additional kidney stones found. It is concluded that, following surgical treatment of hyperparathyroidism, the long-term outcome regarding renal function may be more favourable than has hitherto been thought.

Current Report

Rhabdomyolysis is diagnosed based on the levels of blood biomarkers such as creatine kinase (CK), but the use of CK levels to predict long-term renal function remains controversial. This current report presents a case with a very high CK level with the presentation of acute kidney injury (AKI) who regained full renal function. A 29-year-old man, in a manic mood and presenting with dyspnoea, was admitted to hospital following an episode of ketamine use along with a history of drug abuse. The laboratory analyses identified rhabdomyolysis (CK, 35 266 U/l) and AKI (serum creatinine, 3.96 mg/dl). Despite treatment with intravenous normal saline (4000 ml/day), his CK level reached at least 300 000 U/l. He underwent 13 sessions of haemodialysis and his renal function fully recovered. The final measurements were serum creatinine 1.0 mg/dl and CK 212 U/l. These findings support the view that the predictive power of CK level on AKI is limited, especially regarding long-term renal function. Close follow-up examinations of renal function after haemodialysis are mandatory for patients with rhabdomyolysis.

Abstract Background and Aims Marathon running induces AKI even in adequately prepared and healthy athletes. Heat stress, maintained during more than 2h, has been proposed as one of the leading causes of AKI in marathons runners. Other possible explanations of AKI in this setting could be associated with a reduction of blood supply to the kidneys during the exercise, inadequate hydration or actual structural damage due to microtraumatisms. However, the effect of vigorous exercise of shorter duration on renal function has not been previously described although most risk factors described could also affect kidney function in this type of physical activity. Method 40 volunteer healthy athletes were enrolled in this study. Subjects participated in two physical tests (10km running, 1.5km swimming) which were separated by at least two weeks from each other. These tests were chosen because of their similar oxygen consumption rate and metabolic load. Vitals, blood and urine samples were collected immediately before and after each test. Informed consent was obtained from all participants. The project was funded by Consejería de Sanidad, Junta de Castilla y León (GRS1732/A/18). Results Athletes ranged from 23 to 53 years old. 35% were female. A comparison of hemodynamic and analytical parameters is summarized in Table 1. Running induced a significantly higher rise of serum creatinine and inflammatory markers compared to swimming. Additionally, running caused an increment of serum phosphorus and uric acid levels. Both types of exercise caused a mild increase of urinary albumin/creatinine ratio. Conclusion Compared to swimming, running was associated with a greater rise of serum creatinine, possibly linked to a higher degree of acute inflammation and blood flow redistribution to the muscles. The rise of serum uric acid levels may be associated with increased metabolism and reduced elimination of this molecule while running.

The general objective of this work is to identify a set of electronic governance practices for the executive power of the Brazilian States and Federal District, to measure and relate them to the economic and social development of the respective States and Federal District. In order to achieve this objective, the authors first used bibliographic research to build the theoretical platform about electronic governance and controllership in public management and the identification of electronic governance practices; next, a measurement and monitoring index of the development of electronic governance – 2013 is proposed. The Pearson correlation test was performed in order to verify the correlation between electronic governance and economic and social development indexes – GDP AND GDP per capita – and HDI and Gini, respectively. Lastly, the 2009 electronic governance index was used for comparison purposes. By comparing the results of the correlation and the percentage of the implemented practices, it was then concluded that the States with the highest GDP, the highest HDI and the lowest Gini are those which have the highest number of implemented electronic governance practices.
