Bilateral Adrenal Myelolipoma, A Case Presentation and Brief Literature Review.

As a rare and normally-benign and functionless tumor, primary adrenal myelolipoma comprises adipose tissue and myeloid cells, and its diagnosis is usually difficult owing to its asymptomatic nature. Imaging techniques can detect these masses in over 90% of the cases. CT scan is the most sensitive imaging technique, which can display the tissue nature of this tumor with a high resolution. The present case report involves a 45-year-old woman with bilateral adrenal myelolipoma diagnosed with imaging methods.

Prevalence of fibromyalgia in hemodialysis patients.

This study sought to determine the prevalence of fibromyalgia syndrome and to identify whether fibromyalgia was associated with various clinical symptoms and laboratory parameters in hemodialysis patients. One hundred and forty-eight hemodialysis patients were examined for fibromyalgia symptoms according to the American College of Rheumatology criteria. Demographic characteristics, as well as causes of kidney failure, dialysis duration, and symptoms related to fibromyalgia were investigated. Of 148 patients, 18 (12.2%) were diagnosed with fibromyalgia. Patients with fibromyalgia had significantly poorer sleeping satisfaction than the control group (P = .02).The Beck Depression Inventory score was higher in 77.8% of the fibromyalgia patients than that in the control group (P = .006), but there was no significant difference in the anxiety score between the two groups (P = .86).In conclusion, there was a higher prevalence of fibromyalgia in hemodialysis patients than previously reported. Sleep disturbances and depression levels correlated with fibromyalgia.

Calcium and vitamin D supplementation and risk of kidney stone formation in postmenopausal women.

INTRODUCTION: Calcium and vitamin D are essential structural components of the skeletal system, which prevent osteoporosis after menopause. However, there is a controversial debate on the association between the intake of calcium and vitamin D supplements and the increased risk of formation of kidney calculi in postmenopausal women. which yet have to be confirmed. This study aimed to compare the metabolic changes after supplementation of calcium and vitamin D and examine the risk of stone formation. MATERIALS AND METHODS: Fifty-three postmenopausal women referred to rheumatology clinic who had no history of kidney calculi, bone diseases (apart from osteoporosis), metabolic, and rheumatic disorders and had not been receiving calcium, diuretics and calcitonin were investigated. Renal ultrasonography and blood tests were performed and the urine calcium levels were measured for a period of 24 hours for all patients. The examinations were repeated after a 1- year period of treatment with supplemental calcium (100 mg/d) and vitamin D (400 IU/d) and compared with the data before the treatment. RESULTS: After 1 year, asymptomatic lithiasis was confirmed in 1 of 53 patients (1.9%) using ultrasonographic examination. No significant differences were found between the 24-hour urine and blood calcium levels before and after the treatment. CONCLUSIONS: Our findings showed that oral intake of calcium and vitamin D after 1 year has no effect on the urinary calcium excretion rate and the formation of kidney calculi in postmenopausal women.

Changes of serum calcium, phosphorus, and parathyroid hormone concentrations and ocular findings among patients undergoing hemodialysis.

There are various reports of ocular abnormalities in metabolic disorders. This study was done with the aim to investigate the relationships between the amounts of serum calcium, phosphorus, and parathyroid hormone concentrations and ocular findings in patients undergoing hemodialysis. Fifty eight patients with end stage renal failure undergoing hemodialysis were randomly selected and enrolled in this prospective study. Demographic data, history of diabetes mellitus and hypertension, and duration of hemodialysis were recorded. Serum calcium, phosphorus, alkaline phosphatase (ALP), and parathyroid hormone (PTH) concentrations were measured. Also, blood urea nitrogen (BUN) and weight of the patient was measured just before and three minutes after the hemodialysis. Patients also underwent a complete ocular examination including visual acuity, intraocular pressure (IOP), biomicroscopic examination, and fundoscopy. In univariate analysis, adverse relationships were found between the ocular hypertension and ALP concentration (P = 0.017) and also between the visual acuity and phosphorus concentration (P = 0.033). However, in multivariate regression analysis and with regard to the patients' characteristics and medical history in a multivariate model, no relationships were found between ocular findings and serum calcium, phosphorus, ALP, and PTH concentrations. No relationships were found between the serum concentrations of calcium, phosphorus, ALP, and PTH and ocular findings in patients with end stage renal failure undergoing hemodialysis.

Prophylactic fluid therapy in crushed victims of Bam earthquake.

BACKGROUND: Acute kidney injury (AKI) is a severe and preventable problem of crushed earthquake victims. Early hydration therapy started before fully removing earthquake rubbles has been claimed to play a decisive role in AKI prevention, which saves the necessity of later dialysis. However, the extent, quality, and appropriateness of its know-how are controversial. METHODS: Processing clinical and paraclinical data gathered from Bam earthquake victims older than 15 years, we tried to determine correlations between the time of being under the rubbles (TUR), the level of serum creatine phosphokinase (CPK), the delayed onset of fluid therapy (DFT), and finally the volume of intravenous fluid received per day (VFR) with the formation of AKI and the need for dialysis. RESULTS: There is a direct and significant relation between the intensity of the trauma (TUR and CPK) and DFT with the occurrence of AKI and need for dialysis (P < .001). However, as the VFR increases, the occurrence of AKI and the need for dialysis significantly decrease (P = .005). Based on multivariate analysis, the occurrence of AKI and the need for dialysis are primarily affected by CPK, TUR, and VFR; and DFT has been dropped out. The analysis showed the preventive role of VFR more than 6 L in severe rhabdomyolysis patients and of at least 3 L in moderate ones in development of AKI and dialysis. CONCLUSIONS: In the severely rhabdomyolized patients (CPK ≥ 15,000), higher volumes of prophylactic fluid (VFR >6 L) are required, whereas in less-traumatized patients, lower volumes (3-6 L) would be effective.

Practical strategies to reduce morbidity and mortality of natural catastrophes: a retrospective study based on Bam earthquake experience.

BACKGROUND: Critical analysis of shortcomings of emergency medical management of earthquake casualties will provide an invaluable insight to improve outcomes for future events. Using a critical analysis methodology to evaluate the quality of emergency medical management after Bam earthquake, we suggest a practical strategic approach to decrease morbidity and mortality after such events. METHODS: We designed a questioner to register the basic demographic data and the key biologic parameters of all rescued victims arriving in hospitals. Based on that questioner a data bank was created and used for different analyses. In addition, published official reports and on the scene observations of our nephrologist colleagues were other sources of our data. RESULTS: Bam earthquake was publicly announced more than six hours after its occurrence. The earliest time when local and international rescue teams arrived at the scene was 12 hours after the disaster. Fifty-four percent of hospital inpatients had been admitted on the second or third day after the earthquake. The mean time of being under the rubble was 4.8+/-4.9 hours. The mean time between extrication and initiation of intravenous fluid infusion was 18.9 hours (min: 10 minutes, max: 96 hours). CONCLUSION: Problems encountered in the aftermath of the Bam earthquake were related to the lack of prepared action plan and data management system. Here, we present a specifically designed earthquake chart. By following the chart, rescue paramedic personnel and emergency medical teams will be able to recognize high-risk victims, in order to provide timely medical management.

Epidemiologic aspects of the Bam earthquake in Iran: the nephrologic perspective.

BACKGROUND: Acute renal failure is a serious, preventable, and potentially reversible midterm complication after mass disasters. In 2003, an earthquake struck Bam, Iran. This article studies the epidemiologic aspects of the earthquake from a nephrologic perspective. METHODS: A questionnaire was sent to the reference hospitals. The resulting database of 2,086 traumatized patients hospitalized in the first 10 days was analyzed. RESULTS: Mean age was 29.0 +/- 15.6 years. Compared with the resident population, the percentage of patients was lower among children and teenagers younger than 15 years and higher among young and middle-aged adults (P < 0.001). There was no significant difference between mean ages of patients with acute renal failure and other patients. Time under the rubble was longer for patients with acute renal failure (6.2 +/- 4.1 versus 2.1 +/- 3.9 hours; P < 0.001). These patients were hospitalized later (3.1 +/- 2.8 versus 1.5 +/- 1.7 days after the disaster; P < 0.001) and longer (16.7 +/- 12.8 versus 12.5 +/- 11.3 days; P < 0.001). Sepsis (11.6% versus 0.5%), disseminated intravascular coagulation (7.3% versus 0.3%), adult respiratory distress syndrome (9.1% versus 1.4%), fasciotomy (38.9% versus 1.9%), amputation (6.1% versus 0.5%), and death (12.7% versus 1.9%) were markedly more frequent among patients with acute renal failure (P < 0.001 for all). CONCLUSION: Hospitalized patients were mostly young and middle-aged adults. Patients with acute renal failure were entrapped longer and hospitalized later and for longer periods. Medical complications, surgical procedures, and mortality were greater in the latter group. Early extrication and quick hospitalization with appropriate multidisciplinary care are cornerstones to prevent acute renal failure and its subsequent mortality in earthquake conditions.
