PERCUTANEOUS NEPHROSTOMY FOR RELIEF OBSTRUCTIVE UROPATHY: BENIGN VERSUS MALIGNANT DISEASE

Objective: This study aimed to find out the effectiveness of percutaneous nephrostomy (PCN) as palliative decompression of the obstructed urinary system. Materials & Methods: A case control study was performed with 118 patients (69 female and 49 male) with obstructive uropathy who were undergoing PCN during 2009 until 2012, retrospectively. The mean of age was 50.03 years. The PCN technique involves an ultrasound-guided puncture of the dilated collecting system with nephrostomy trocar than insert an 8 Fr nasogastric tube as nephrostomy catheter. Differences of renal function between benign and malignancy were assessed using Independent t-test. Changes in renal function after procedure were expressed as mean ± SD and analyzed using Pair t-test. Results: There was no procedure-related mortality. The most cause of malignancy was cervix cancer (36.4%) while the result of a benign process was 28.8% of urinary tract stones. Dialysis before procedure were performed in 43 (36.4%) consisting of 42 malignancies and 1 benign process. Improvement in renal function were statistically significant both benign and malignant groups seen in the levels of creatinine and blood urea nitrogen (BUN) before and after procedure (p<0.001). The mean differences were also statistically significant at the preoperative creatinine values between benign and malignant processes (p=0.019) but BUN levels before and after as well as postoperative creatinine levels showed no significant difference. Conclusion: PCN is a widely used technique, with a high technical success rate and low rate of complications. Obstructive uropathy due to benign processes had a better prognosis than malignancy after PCN treatment. Hemodialysis was mainly performed in patients with malignancy prior to PCN.

Objective: Study was aimed to see the effects of hypothyroidism on GFR as a renal function. Material and methods: Total of Fifty-eight patients were included in the study. Out of those forty-eight patients were female and the rest were male. Out of fifty eight patients, fifty three patients were of thyroid cancer in which hypothyroidism was due to discontinuation of thyroxine before the administration of radioactive iodine for Differentiated thyroid cancer.Moreover, remaining five patients were post radioactive iodine treatment (for hyperthyroidism) hypothyroid. All of the patients were above eighteen years of age with TSH value > 30µIU/ml. Pregnant and lactating females were excluded.Renal function tests (urea/creatinine, creatinine clearance) and serum electrolytes followed by Tc-99m-DTPA renal scan for GFR assessment (GATES’ method) were carried out in all subjects twice during the study, One study during hypothyroid state (TSH > 30 µIU/ml) and other during euthyroid state (TSH between 0.4 to 4µ IU/ml). The results of Student’s t-test showed significant difference in renal functions (Urea, creatinine, creatinine clearance, GFR values) in euthyroid state and hypothyroid state (p-value <0.05). RESULTS: In case of creatinine the paired t test reveal the mean 1.014±0.428, with standard error of 0.669 within 95% confidence interval, for creatinine clearance 80.11±14.12 with standard error of 1.94 within 95% confidence intervals, for urea the mean 28±12.13 with standard error of 1.607 within 95% confidence intervals and for GFR for individual kidney is 38.056±8.56 with standard error of 1.3717 within 95% confidence interval. There was no difference in the outcome of the 2 groups. Conclusion: Hypothyroidism impairs renal function to a significant level and hence needs to be prevented and corrected as early as possible.

The Impact

Abstract Dam construction is one of the most popular solutions for managing water resources. In recent years, changes in patterns of regional seismicity associated with large impoundment dams have raised concerns among environmentalists. In this study, five large dams located in Iran were studied from this perspective. The Gutenberg-Richter, linear regression and T-test were used to examine the seismic changes in the radius of 100 km of each of the dams during a twenty-five-year period before and after the construction of the dams. The results revealed that the seismicity level and relative density of large and small earthquakes in three of these dams have increased after dam construction. A significant difference between the magnitude of earthquakes, as well as the number of earthquakes before and after the construction of dams in the region, was recognized. However, the results of the T-test statistical analysis indicated that the mean depth of the earthquakes and their distance from the dams before and after construction have not changed significantly. Overall, these results indicated that the construction of large impoundment dams has been associated with some changes in patterns of regional seismicity. The findings would guide researchers to further investigate the type of impacts that dam construction may have on seismicity patterns.

Introduction: Balance in the elderly is one of the important issues, and imbalance can create irreparable problems for the elderly. The aim of this study was to investigate the effect of Frenkel balance exercise and aerobic exercise (walking) on improving the balance of elderly patients in Kerman province in 2016-2017. Methods: We used a randomized block design, with 4 participants in each block; 48 elderly men and women living in the nursing homes of Kerman province were randomly assigned to two groups, balance (Frenkel) exercises and aerobic exercises (walking). The two groups performed Frenkel exercises and aerobic exercises (walking) for three 10- to 15-min sessions a week for five weeks. The balance time using the Sharpened Romberg test was recorded to measure static balance and the Get Up and Go test used to measure dynamic balance before and after the exercise program. To describe the variables studied, central tendency indicators and dispersion were used. Paired t-test was used to compare the time of balance before and after intervention and independent t-test to compare changes in balance time between two groups. Results: The mean static balance (with Sharpend Römberg test) was increased from 3.16 s to 6.01 s in Frenkel exercise, and from 3.33 s to 4.95 s in aerobic training group, indicating an improvement in the static balance after intervention. The mean time of dynamic balance (in the Get Up and Go test) during Frenkel exercise reduced from 17.07 s to 12.03 s, and during aerobic training from 17.08 s to 10.9 seconds, indicating an improvement in dynamic balance (p < 0.01). However, there was no significant difference in the mean changes in the duration of dynamic and static balance before and after intervention in the two groups. Conclusion: Both Frenkel exercise and walking equally improve static and dynamic balance in the elderly in different settings.

Background & Aim: Anemia is one of the most common complications of chronic renal failure, which is associated with increased fatigue, dyspnea, depression, malaise, prolonged hospitalization and mortality. Some patients are resistant to erythropoietin therapy. Therefore, the purpose of this study was to determine the effect of thyme honey on anemia in hemodialysis patients. Methods & Materials: The present clinical trial was conducted in 2018 at Kowsar Hospital of Semnan on hemodialysis patients randomly selected with convenience sampling method within two groups of case (n=28) and control (n=27). The case group received thyme honey (33 g) daily for one month. The control group did not consume thyme honey. Blood samples were taken from the patients before and after the intervention with 10-hour fasting and then blood parameters were assessed. Results: The mean ±SD reduction rate in hemoglobin level was 0.46±0.96 in the case group and 0.23±3.15 g/dl in the control group, but no significant difference using independent t-test (P=0.758). The mean±SD reduction rate in hematocrit percentages was 1.20±2.78 in the case group and 0.11±8.53 in the control group, but there is no significant difference between the two groups using independent t-test (P=0.590). Conclusion: Results showed that daily administration of 33 grams of thyme honey had no effect on anemia in hemodialysis patients. Further studies are recommended with modification of the methodology regarding the type, dose, duration and instructions of honey consumption for better results.

Background: The crisis caused by the child's illness and hospitalization affects all family members. Fear, worry, and anxiety are common issues of hospitalized children’s mothers. Betty Newman's system model plays a vital role in adapting to stress detection and control. Objectives: This study aimed to examine the effect of the behavioral systems model on the concerns of mothers of children admitted to the surgical ward. Methods: This quasi-experimental study was conducted on 60 mothers of children admitted to the surgical ward of the Mousavi Hospital, Gorgan, Iran, in 2020. The participants were selected using convenience sampling and then divided into test and control groups using non-probability sampling. According to Neuman's systems model, participants in the test group received nursing care in 3 - 4 sessions (each lasting 30 - 45 minutes). Participants in the control group received only routine ward care. Data were collected using the Parental Concern Scale and analyzed with IBM SPSS Statistics 21 software using statistical tests (analysis of covariance, unpaired samples t-test, and paired sample test). Results: The mean score of maternal concerns before the intervention was 42.6 ± 3.06 in the control group and 43.21 ± 2.27 in the test group. The results of the independent samples t-test did not show any significant difference between the groups in terms of maternal concerns (P = 0.11). The mean post-intervention maternal concern score was 37.6 ± 2.71 and 41.716 ± 2.55 in the test and control groups, showing a significant difference between the groups as indicated by the t-test results (P < 0.01). However, the paired t-test outcomes showed no difference in the mean maternal concern score in the control group before and after the intervention (P = 0.92). In contrast, there was a significant difference in the mean maternal concern score in the test group before and after the intervention (P < 0.01). Conclusions: Given the effectiveness of Betty Neuman’s systems model, it can be used as a low-cost, effective care method to reduce maternal stress as the model was developed for understanding clients’ and caregivers’ needs and reducing their stress.
