    Sudden unexplained anuria in renal transplant patients could well be secondary to occult internal hemorrhage rather than the usual vascular thrombotic or obstructive event, even in the completely stable patient. Urgent intervention in such bleeding states can save patient's life and graft function. Graft survival is very exceptional in graft artery or vein thrombosis. Contrary to hemorrhagic events, life is usually not threatened by thrombotic events involving the renal graft vasculature. We present here three unfortunate cases that shared the problem of unexpected anuria due to a hemorrhagic event in apparently stable renal transplant patients. (author)

    Savić, Slaviša; Vukotić, Vinka; Lazić, Miodrag; Savić, Nataša


    To present our experience with emergency ureteroscopic lithotripsy (URSL) for ureteral calculi associated with acute kidney injury (AKI). We retrospectively evaluated the 61 patients consisted of 90 ureteral units (UU), who underwent URSL. The cause of anuria was bilateral calculus obstructions in 29 cases, and unilateral calculus obstruction with, absent, nephrectomized contralateral kidney in 32 cases. In the case of bilateral synchronous ureteric calculi same-session bilateral ureteroscopy (SBBU) was done. The duration of anuria varied between 12 to 72 hours. At the end of the procedure, ureteral stent was systematically left in place in all patients. Surgery was performed 6-12 hours after admission to hospital. Patients were followed at least 1 month postoperatively. The stone free rates (SFR) were determined as baseline, on the first post-operative day, and as overall on the 30 days after procedure. The greatest success was achieved in the distal localization of stones up to 10 mm (93%). Renal function returned in 51 (83.6%) patients within 7 days. In 18 (29.5%) patients [18 (20%) UU] we performed second procedure as extracorporeal shockwave lithotripsy in 16.7% and open surgery in 2.2%. In 43 (70.5%) patients URSL was a successful therapeutic approach in dealing with pain, obstruction and calculus. Calculus anuria is a medical emergency that requires rapid diagnosis and prompt treatment for the purpose of decompression. URSL is the proper method of choice for selected patients and can be performed safely and has high success rates with minimal morbidity.

  3. Investigating the mechanism for maintaining eucalcemia despite immobility and anuria in the hibernating American black bear (Ursus americanus). (United States)

    Ursine hibernation uniquely combines prolonged skeletal unloading, anuria, pregnancy, lactation, protein recycling, and lipolysis. This study presents a radiographic and biochemical picture of bone metabolism in free-ranging, female American black bears (Ursus americanus) that were active (spring bears and autumn bears) or hibernating (hibernating bears). Hibernating bears included lactating and non-lactating individuals. We measured serum calcium, albumin, inorganic phosphate, creatinine, bone specific alkaline phosphatase (BSALP), CTX, parathyroid hormone, insulin-like growth factor-I (IGF-l), leptin, 25-hydroxyvitamin D [25(OH)D], 1,25-dihydroxyvitamin D [1,25(OH)(2)D] and sclerostin from 35 to 50 tranquilized hibernating bears and 14 to 35 tranquilized spring bears. We compared metacarpal cortical indices (MCI), measured by digital X-ray radiogrammetry, from 60 hunter-killed autumn bears and 79 tranquilized, hibernating bears. MCI was greater in autumn than winter in younger bears, but showed no seasonal difference in older bears. During hibernation eucalcemia was maintained, BSALP was suppressed, and CTX was in the range expected for anuria. During hibernation 1,25(OH)(2)D was produced despite anuria. 1,25(OH)(2)D and IGF-I were less in hibernating than spring bears. In a quarter of hibernating bears, sclerostin was elevated. Leptin was greater in hibernating than spring bears. In hibernating bears, leptin correlated positively with BSALP in non-lactating bears and with CTX in lactating bears. Taken together the biochemical and radiographic findings indicate that during hibernation, bone turnover was persistent, balanced, and suppressed; bone resorption was lower than expected for an unloaded skeleton; and there was no unloading-induced bone loss. The skeleton appears to perceive that it was loaded when it was actually unloaded during hibernation. However, at the level of sclerostin, the skeleton recognized that it was unloaded. During hibernation leptin

  4. Successful Management of Repetitive Urinary Obstruction and Anuria Caused by Double J Stent Calculi Formation after Renal Transplantation

    Full Text Available This report firstly describes an extremely rare case of repetitive double J stent calculi formation after renal transplantation caused by the antihyperparathyroidism (HPT drug calcitriol. In 2012, a woman initially presented to our hospital for anuria with lower abdominal pain. She was diagnosed with allograft hydronephrosis and double J stents obstruction by calculi formation after transplantation and treated with triplicate stents replacements in another hospital without clinical manifestations improvements. Through detailed exploration of medical history, we conclude that the abnormal calculi formation is due to the calcitriol (1,25-dihydroxyvitamin D3 administration, a drug which can increase renal tubular reabsorption of calcium for treating posttransplant HPT bone disease. After discontinuing calcitriol, the patient was stone-free and had a good recovery without severe complications during the 9-month follow-up. Our novel findings may provide an important clue and approach to managing formidable repetitive double J stent calculi formation in the clinical trial.

    The relationship between residual urine output and postoperative survival in maintenance hemodialysis patients is unknown. To explore the relationship between amount of urine before surgery and postoperative mortality and differences between postoperative nonanuria and anuria in maintenance hemodialysis patients. A total of 109 maintenance hemodialysis patients underwent major operations. Anuria was defined as urine output <30 mL in the 8 hours before the first session of postoperative dialysis. Propensity scores for postoperative anuria were developed. Postoperative residual urine output was 159.2 mL/8 h (SD, 115.1) in 33 patients; 76 patients were anuric. Preoperative residual urine output and adequate perioperative blood transfusion were positively related to postoperative urine output. Propensity-adjusted 30-day mortality was associated with postoperative anuria (odds ratio [OR], 4.56; 95% confidence interval [CI], 1.16-17.96; P = .03), prior stroke (OR, 4.46; 95% CI, 1.43-13.89; P = .01) and higher disease severity (OR, 1.10; 95% CI, 1.00-1.21; P = .049) at the first postoperative dialysis. OR of 30-day mortality was 5.38 for nonanuria to anuria vs nonanuria to nonanuria (P = .03) and 5.13 for preoperative anuria vs nonanuria to nonanuria (P = .01). By Kaplan-Meier analysis, 30-day mortality differed significantly among patients for nonanuria to nonanuria, anuria, and nonanuria to anuria (log rank, P = .045). Patients with preoperative nonanuria and postoperative anuria had higher mortality than did patients with no anuria before and after surgery and patients with anuria before surgery. Postoperative residual urine output is an important surrogate marker for disease severity.

  20. Electro-thermal injuries due to high-current accidents with special regard to the skeletal muscles

    Energy Technology Data Exchange (ETDEWEB)

    Rausch, M.


    Seven patients suffering from high-current accidents with different degrees of severity are reported on. Damages to the striped musculature are preferentially considered. When the function of the cellular membrane is affected by an electric current, the Na/sup +//K/sup +/ mechanism collapses due to an increase of membrane permeability for calcium. Depolarisation, development of contractures, changes of the fibrillar structures and decay of the stripes or swelling of the Q (A) substance were found to indicate damage. A particular effect of electrothermal muscle damages is the affection of other organs, e.g. of the kidneys, provoked by an increased chromoprotein production and a higher output of myoglobin and hemoglobin. Since in case of an accident due to electric current affecting the musculature, more acid substances enter the vascular system, an acute renal damage provoked by an alkalinisation of the urine, shall be treated by drugs. In most cases, an anuria, occurring several days after deep burn of musculature, is a so-called constipational anuria, if it is not an anuria induced by a decrease of blood pressure or by shock. The therapy of wounds due to electrical burning depends on the size of the affected skin area and down to which depth the tissue is burnt. Particular attention must be paid to the affection of bones being situated in the depth of wounds due to burning. In the last part of the study possible reconstructive and ensuing rehabilitation measures are indicated.

  1. [Revascularization surgery of an anuric solitary kidney using the left colic artery as a free graft]. (United States)

    da Gama, A Dinis; Nunes, J Silva; Cunha e Sá, Diogo; Pedro, Luís Mendes


    The thrombotic occlusion of one renal artery may become completely asymptomatic, due to the functionality of the contralateral kidney. However, in rare circumstances, such is the case of individuals with a solitary kidney, a situation of anuria and acute renal failure may constitute the main presentation of the condition. The authors report the clinical case of a 43 year old male patient, with the previous diagnosis of an infrarenal aortic occlusion and a single left kidney, who developed a thrombotic occlusion of the renal artery, with anuria and acute renal failure. The patient underwent an emergency revascularization procedure, consisting in the implantation of a prosthetic bypass graft from the superceliac aorta to the renal artery, with immediate recovery of the diuresis and renal function. Seventeen months later as a consequence of an anastomotic hyperplasia, an occlusion of the bypass graft occurred, again with anuria and acute renal failure. The patient was reoperated on and due to the inadequacy of both saphenous veins to be used as the material of choice for the revascularization procedure, a redundant segment of the left colic artery (Riolan's arcade) was removed and used as an interposition graft, from the middle colic artery to the renal artery, followed by an immediate restoration of diuresis and renal function. The singular and recurrent character of this clinical condition and the utilization of an original, eventually unique and well succeeded revascularization procedure, prompted its presentation and divulgation.

  2. Kidney Scanning with Hippuran: A Necessary Complement for Correct Interpretation of Renography in the Transplanted Kidney

    Energy Technology Data Exchange (ETDEWEB)

    Every impairment of the kidneys' blood supply, and the production or excretion of urine, is reflected by abnormal renograms that are not specific enough in the information they provide. The subsequent performance of renal scans with Hippuran {sup 131}I adds information to the topographical distribution of the Hippuran {sup 131}I in the renal parenchyma, and to the dynamics of its transport through the urinary system. The information thus obtained is valuable in itself and is necessary for the correct interpretation of renography. We have found this specially useful in the follow-up of the transplanted kidneys. In cases of anuria following renal transplantation, the renogram is useful for indicating that renal circulation is present in the transplanted kidney but is inadequate as a method to differentiate between other renal and post-renal causes of anuria. The anuric transplanted kidney should be scanned thirty minutes after the injection of Hippuran {sup 131}I. Patterns of complementary results of renograms and renal scannings are presented that correspond to prerenal, renal and postrenal causes of anuria, with all the important therapeutic implications this differential diagnosis has.

  3. Advances in diagnosis and treatment of hepatorenal syndrome type of acute kidney injury in patients with liver cirrhosis

    Directory of Open Access Journals (Sweden)

    SONG Tingxue


    Full Text Available Acute kidney injury (AKI is a common complication of liver cirrhosis and mainly manifests as a rapidly elevated serum creatinine level, a reduced glomerular filtration rate, and oliguria or anuria. Type 1 hepatorenal syndrome (HRS-1 is a special type of AKI, and patients with untreated HRS-1 have an extremely high risk of death. Early diagnosis and treatment are of great importance. This paper summarizes the latest diagnostic criteria for hepatorenal syndrome (HRS type of AKI and research advances in the treatment of HRS-1.

  5. Severe loin pain following renal biopsy in a high-risk patient: A case report of a rare combination of pseudoaneurysm and arterio-venous fistula

    Directory of Open Access Journals (Sweden)

    Desai Madhav


    Full Text Available We report a 50-year-old male patient with diabetes mellitus and hypertension who presented with low-grade fever, anuria and renal failure. He had no prior history of nephropathy and retinopathy. Since anuria persisted, a renal biopsy was performed using automated gun, under ultrasound guidance. Two hours after the renal biopsy was performed, the patient developed severe left loin pain that required analgesics and sedatives. Ultrasound of the abdomen performed immediately, two hours and four hours after the biopsy, did not reveal any hematoma. The hemoglobin was stable when the patient developed loin pain, but after eight hours decreased to 9.1 g/dL, and computed tomography scan of the abdomen revealed a big peri-nephric hematoma around the left kidney. He was managed with blood transfusions and a selective angiogram was done. It revealed a pseudoaneurysm and arterio-venous fistula from the segmental artery of lower pole of the left kidney; both were closed by using microcoils and liquid embolic agent N-butyl-cyanoacrylate (NBCA. The only risk factor the patient had at the time of renal biopsy was severe renal failure. Our case suggests that severe loin pain immediately after renal biopsy in a patient with renal failure warrants careful follow-up of hemoglobin and imaging, even if initial imaging is normal. Further fall of hemoglobin necessitates early evaluation with angiogram, which helps in diagnosing the treatable, although rare, complications like pseudoaneurysm and arterio-venous fistula.

  6. Malaria induced acute renal failure: A single center experience

    KV Kanodia; AV Vanikar


    Malaria has protean clinical manifestations and renal complications, particularly acute renal failure that could be life threatening. To evaluate the incidence, clinical profile, ou come and predictors of mortality in patients with malarial acute renal failure, we retrospectively studied the last two years records of malaria induced acute renal failure in patients with peripheral smear positive for malarial parasites. One hundred (10.4%) (63 males, 37 females) malaria induced acute renal failure amongst 958 cases of acute renal failure were evaluated. Plasmodium (P). falciparum was reported in 85%, P. vivax in 2%, and both in 13% patients. The mean serum creatinine was 9.2 ± 4.2 mg%, and oligo/anuria was present in 82%; 78% of the patients required hemodialysis. Sixty four percent of the patients recovered completely, 10% incompletely, and 5% developed chronic kidney failure; mortality occurred in 21% of the patients. Low hemoglobin, oligo/anuria on admission, hyperbilirubinemia, cerebral malaria, disseminated intravascular coagulation, and high serum creatinine were the main predictors of mortality. We conclude that malaria is associated with acute renal failure, which occurs most commonly in plasmodium falciparum infected patients. Early diagnosis and prompt dialysis with supportive management can reduce morality and enhance recovery of renal function (Author).

  7. Single-dose-dexketoprofen-induced acute kidney injury due to massive rhabdomyolysis. (United States)

    Sav, Tansu; Unal, Aydin; Erden, Abdulsamet; Gunal, Ali Ihsan


    A 70-year-old male patient was admitted complaining of weakness and pain in his arms and lower limbs. His serum creatine kinase and serum creatinine were markedly elevated (36,248 IU/L and 2.8 mg/dL, respectively). He had taken dexketoprofen trometamol because of a common cold, which had developed the previous night. Acute kidney injury caused by dexketoprofen-induced rhabdomyolysis was diagnosed by ruling out other possible causes, such as dermato/polymyositis, myxedema, brucellosis, and hepatitis. Dexketoprofen administration was stopped. As diuresis did not restore spontaneously, the patient was treated with I.V. alkaline solutions and mannitol. Hemodialysis was performed because of anuria and severe metabolic acidosis. The patient's renal function later recovered. In conclusion, dexketoprofen may be a potential risk factor for acute kidney injury and rhabdomyolysis.

    Acute kidney injury (AKI) secondary to near-drowning is rarely described and poorly understood. Only few cases of severe isolated AKI resulting from near-drowning exist in the literature. We report a case of near-drowning who developed to isolated AKI due to acute tubular necrosis (ATN) requiring dialysis. A 21-yr-old man who recovered from near-drowning in freshwater 3 days earlier was admitted to our hospital with anuria and elevated level of serum creatinine. He needed five sessions of hemodialysis and then renal function recovered spontaneously. Renal biopsy confirmed ATN. We review the existing literature on near-drowning-induced AKI and discuss the possible pathogenesis.

  9. Suicidal intoxication with potassium chlorate successfully treated with renal replacement therapy and extracorporeal liver support. (United States)

    Sein Anand, Jacek; Barwina, Małgorzata; Zajac, Maciej; Kaletha, Krystian


    We present a case of a 22-year-old male who, in a suicide attempt, ingested approximately 200 g of potassium chlorate. Upon admission to the hospital, he presented in full respiratory failure with cyanosis. Methylene blue antidote was given but found to be ineffective. The patient was intubated and mechanical ventilation was initiated. Because of renal failure with anuria, intermittent haemodialysis (iHD) followed by continuous venovenous hemodiafiltration (CVVHDF) was performed. His hospital stay was also complicated by hemolysis, disseminated intravascular coagulation, and atrial fibrillation. Transfusions of packed red blood cells, platelets, and fresh frozen plasma were necessary to correct the deficits. He also developed liver failure and required two sessions of molecular adsorbent recirculating system (MARS) therapy. On day 14 of his hospitalization, he regained consciousness, as well as full respiratory and circulatory function. There are no controlled studies addressing management of potassium chlorate poisoning. We suggest that early renal replacement therapy should be strongly considered.

  10. Association of Kt/V and creatinine clearance with outcomes in anuric peritoneal dialysis patients. (United States)

    Fried, Linda; Hebah, Nasser; Finkelstein, Fredric; Piraino, Beth


    The 2006 Kidney Disease Outcomes Quality Initiative recommended a minimum total Kt/V of 1.7, eliminated creatinine clearance (Ccr) as a target, and recommended the use of ideal body weight to calculate Kt/V. We assessed these recommendations as predictors of outcomes in anuric peritoneal dialysis patients. Retrospective observational study using administrative data. 1,432 peritoneal dialysis patients with anuria from January 1, 1994, to January 31, 2005, in a national sample (1,428 with Kt/V, 1,416 with Ccr). Kt/V and Ccr at anuria; Kt/V based on actual body weight and ideal body weight. Association of dialysis adequacy with mortality and time to first hospitalization after anuria assessed by using accelerated failure time models. 293 anuric patients had Kt/V less than 1.7, 366 had Kt/V of 1.7 to 2.0, and 769 had Kt/V greater than 2.0, using actual body weight for calculation. In unadjusted analyses, Kt/V calculated using actual body weight both less than 1.7 (-41.3%; 95% confidence interval [CI], -55.5 to -22.6) and 1.7 to 2.0 (-26.1%; 95% CI, -42.6 to -4.6) were associated with shorter time to mortality. Kt/V calculated using actual body weight less than 1.7 was associated with shorter time to hospitalization (-38.1%; 95% CI, -50.0 to -23.4), but Kt/V calculated using actual body weight of 1.7 to 2.0 was not a significant predictor (-3.3%; 95% CI, -21.1 to 18.6). After adjustment, Kt/V calculated using actual body weight less than 1.7 remained associated with mortality (-25.3%; 95% CI, -41.1 to -4.8) and hospitalization (-33.4%; 95% CI, -47.1 to -16.0). Ccr did not predict mortality. In unadjusted analysis, Ccr was not associated with hospitalization, but after adjustment, Ccr less than 50 L/wk/1.73 m(2) was significantly associated with shorter time to hospitalization (-19.9%; 95% CI, -35.0 to -1.3). Kt/V using ideal body weight was not a significant predictor in adjusted models. This study was nonrandomized, with few malnourished patients. In addition, there is

Topics considered include breast cancer screening, acute spinal trauma, search for primary cancer of unknown origin, acute anuria, blunt chest trauma, new onset seizures, and spinal cord compression from metastases. Other chapters have been rewritten to enhance the clarity of presentation and to incorporate new techniques such as magnetic resonance imaging, dipyridamole stress testing, and single photon emission computed tomography. The book highlights the expanding role of CT in evaluation of thoracic and abdominal problems, the emergence of magnetic resonance imaging as a vital diagnostic tool for the central nervous system, and the clinical utility of many newly developed radiopharmaceuticals

  12. Imipenem-induced clostridium difficile diarrhea in a patient with chronic renal failure

    Directory of Open Access Journals (Sweden)

    R Enríquez


    Full Text Available An 80-year-old man was diagnosed to have pneumonia and advanced chronic kidney disease. He presented with anuria and hemodialysis, by temporary femoral catheter, was initiated. He was empirically treated with imipenem/cilastatin 500 mg/24 h after hemodialysis. After 10 days of antibiotic intake, he developed severe diarrhea. Diagnosis of Clostridium difficile (CD-associated diarrhea was confirmed by detection of the toxins A and B in his stool. Imipenem therapy was discontinued; Vancomycin 500 mg orally every 6 h and 1000 mg per rectum every day was added. After two weeks of this treatment, the patient reported complete resolution of the diarrhea and stool samples were negative for Clostridium toxin. In this case, the most possible cause of CD colitis was considered to be imipenem because of the temporal relationship between exposure to the drug and onset of symptoms.

    Radiographic, historical, clinical signs, and surgical and histopathologic findings of six dogs with diagnosed cystic uterus masculinus are given. The condition was seen in aged dogs between 4 and 15 years (mean of 8.8 years). There was no breed predisposition, although the larger breeds were involved in this study. The predominant clinical signs were constipation, dysuria and anuria. Lateral survey recumbent abdominal radiographs coupled with negative-or positive-contrast cystography were useful in delineating the bladder and the urethra, thus revealing the smooth-contoured, asymmetrical fluid-filled viscus in the caudal abdomen. The bi-horned cysts were connected to the dorsal urethra through a short blind-ending pedicle. The nonseptic, aspermic, cystic fluid averaged 146.7 ml (range of 100–200 ml). The predominant epithelial lining cells seen were simple columnar to pseudostratified columnar

    The authors report a case of acute kidney injury (AKI) resulting from menstruation-related disseminated intravascular coagulation (DIC) in an adenomyosis patient. A 40-yr-old woman who had received gonadotropin for ovulation induction therapy presented with anuria and an elevated serum creatinine level. Her medical history showed primary infertility with diffuse adenomyosis. On admission, her pregnancy test was negative and her menstrual cycle had started 1 day previously. Laboratory data were consistent with DIC, and it was believed to be related to myometrial injury resulting from heavy intramyometrial menstrual flow. Gonadotropin is considered to play an important role in the development of fulminant DIC. This rare case suggests that physicians should be aware that gonadotropin may provoke fulminant DIC in women with adenomyosis. PMID:20808684

  15. Multi-organ dysfunction in bodybuilding possibly caused by prolonged hypercalcemia due to multi-substance abuse: case report and review of literature. (United States)

    Schäfer, C N; Guldager, H; Jørgensen, H L


    A 26-year-old male bodybuilder was admitted to the surgical department of a Danish community hospital for hematemesis. During the clinical interview, he revealed that he had recently finished a course of anabolic steroids and erythropoietin. The patient also had a previous history of infections and chronic ulcers due to paraffin-oil injections in both upper arms one year before. Over the course of the next few hours, the patient developed signs of multi-organ dysfunction, including pancreatitis, hemorrhagic gastritis, nephropathy with temporary anuria, and respiratory insufficiency, and was transferred to the ICU. After manometric monitoring on the patient's upper arms proved difficult, invasive blood pressure monitoring was used and revealed that the patient was in a state of hypertensive crisis. This case of multi-organ dysfunction was possibly caused by multi-substance-induced hypercalcemia. © Georg Thieme Verlag KG Stuttgart · New York.

    Lim, Seok Tae; Kim, Min Woo; Sohn, Myung Hee


    A 38-year-old woman with end stage renal disease received a living related donor-renal transplant to the right iliac fossa. She developed anuria a week later. Tc-99m MAG 3 renal scintigraphy demonstrated no perfusion, uptake, or excretion of the radioactive tracer from the renal transplant. The expected area of the renal allograft appeared as a photopenic area with increased rim activity. The gallbladder and bowel activities were observed on delayed images at 24 hours. There was no blood flow within the renal artery on renal doppler examination. This case shows total absence of perfusion and function in the infarcted renal transplant with extrarenal excretion of Tc-99m MAG 3 caused by acute renal artery thrombosis

    Sixteen infants, 2 to 35 days of age, had acute renal failure, a diagnosis based on serum creatinine concentrations greater than 1.5 mg/dL for at least 24 hours. Eight infants were oliguric (urine flow less than 1.0 mL/kg/h) whereas the remainder were nonoliguric. To determine clinical parameters useful in prognosis, urine flow rate, duration of anuria, peak serum creatinine, urea (BUN) concentration, and nuclide uptake by scintigraphy were correlated with recovery. Nine infants had acute renal failure secondary to perinatal asphyxia, three had acute renal failure as a result of congenital cardiovascular disease, and four had major renal anomalies. Four oliguric patients died: three of renal failure and one of heart failure. All nonoliguric infants survived with mean follow-up serum creatinine concentration of 0.8 +/- 0.5 (SD) mg/dL whereas that of oliguric survivors was 0.6 +/- 0.3 mg/dL. Peak serum creatinine concentration did not differ between those patients who were dying and those recovering. All infants who were dying remained anuric at least four days and revealed no renal uptake of nuclide. Eleven survivors were anuric three days or less, and renal perfusion was detectable by scintigraphy in each case. However, the remaining survivor (with bilateral renal vein thrombosis) recovered after 15 days of anuria despite nonvisualization of kidneys by scintigraphy. In neonates with ischemic acute renal failure, lack of oliguria and the presence of identifiable renal uptake of nuclide suggest a favorable prognosis

  18. Simultaneous Bilateral Ureteral Calculi: A New Paradigm for Management. (United States)

    To define the need for emergent intervention between patients with simultaneous bilateral ureteral calculi (SBUC) compared to unilateral ureteral calculi (UUC). Patients with SBUC represent a potential urological emergency due to possible anuria or electrolyte imbalance. While conventional practice mandates immediate intervention in these patients, little data exist to define the rate of these events. Records of all patients with ureteral stones treated ureteroscopically over an 11-year period were reviewed to identify those with SBUC. Patient presenting characteristics, time from diagnosis to intervention, and postoperative outcomes were noted. To determine the need for emergent intervention, we compared metabolic and infectious parameters between SBUC patients and age- and sex-matched patients with UUC. A total of 3800 patients presented with ureteral calculi including 42 (1.1%) with SBUC. Two-thirds of patients with SBUC had an established diagnosis of nephrolithiasis. Among the 42 patients with SBUC, 11 (26.2%) were considered emergent due to metabolic (5 of 11, 45.5%), infectious (1 of 11, 9.1%), or both metabolic and infectious indications (5 of 11, 45.5%). No patients required acute dialysis before surgical intervention. Compared to patients with UUC, those with SBUC were significantly more likely to require emergent management (P = .03, odds ratio 2.3). Univariate and multivariate analyses showed this to be due to anuria (P = .001) and acidosis (P = .003). SBUC is an uncommon condition and, in this series, only the minority of patients presented emergently. Therefore, patients with SBUC can often be managed electively if counseled on clinical signs warranting emergent medical attention. Appropriately selected patients have excellent outcomes following single stage bilateral ureteroscopy. Copyright © 2018. Published by Elsevier Inc.

  19. Monocyte chemoattractant protein-1 and interleukin-8 levels in urine and serum of patents with hemolytic uremic syndrome. (United States)

    van Setten, P A; van Hinsbergh, V W; van den Heuvel, L P; Preyers, F; Dijkman, H B; Assmann, K J; van der Velden, T J; Monnens, L A


    The epidemic form of the hemolytic uremic syndrome (HUS) in children is hallmarked by endothelial cell damage, most predominantly displayed by the glomerular capillaries. The influx of mononuclear (MO) and polymorphonuclear cells (PMNs) into the glomeruli may be an important event in the initiation, prolongation, and progression of glomerular endothelial cell damage in HUS patients. The molecular mechanisms for the recruitment of these leukocytes into the kidney are unclear, but monocyte chemoattractant protein-1 (MCP-1) and IL-8 are suggested to be prime candidates. In this study, we analyzed the presence of both chemokines in 24-h urinary (n = 15) and serum (n = 14) samples of HUS children by specific ELISAs. Furthermore, kidney biopsies of three different HUS children were examined for MO and PMN cell infiltration by histochemical techniques and electron microscopy. Whereas the chemokines MCP-1 and IL-8 were present in only very limited amounts in urine of 17 normal control subjects, serial samples of HUS patients demonstrated significantly elevated levels of both chemokines. HUS children with anuria showed higher initial and maximum chemokine levels than their counterparts without anuria. A strong positive correlation was observed between urinary MCP-1 and IL-8 levels. Whereas initial serum IL-8 levels were significantly increased in HUS children, serum MCP-1 levels were only slightly elevated compared with serum MCP-1 in control children. No correlation was found between urinary and serum chemokine concentrations. Histologic and EM studies of HUS biopsy specimens clearly showed the presence of MOs and to a lesser extent of PMNs in the glomeruli. The present data suggest an important local role for MOs and PMNs in the process of glomerular endothelial-cell damage. The chemokines MCP-1 and IL-8 may possibly be implicated in the pathogenesis of HUS through the recruitment and activation of MOs and PMNs, respectively.

  1. Novel treatment strategies for chronic kidney disease: insights from the animal kingdom. (United States)

    Stenvinkel, Peter; Painer, Johanna; Kuro-O, Makoto; Lanaspa, Miguel; Arnold, Walter; Ruf, Thomas; Shiels, Paul G; Johnson, Richard J


    Many of the >2 million animal species that inhabit Earth have developed survival mechanisms that aid in the prevention of obesity, kidney disease, starvation, dehydration and vascular ageing; however, some animals remain susceptible to these complications. Domestic and captive wild felids, for example, show susceptibility to chronic kidney disease (CKD), potentially linked to the high protein intake of these animals. By contrast, naked mole rats are a model of longevity and are protected from extreme environmental conditions through mechanisms that provide resistance to oxidative stress. Biomimetic studies suggest that the transcription factor nuclear factor erythroid 2-related factor 2 (NRF2) offers protection in extreme environmental conditions and promotes longevity in the animal kingdom. Similarly, during months of fasting, immobilization and anuria, hibernating bears are protected from muscle wasting, azotaemia, thrombotic complications, organ damage and osteoporosis - features that are often associated with CKD. Improved understanding of the susceptibility and protective mechanisms of these animals and others could provide insights into novel strategies to prevent and treat several human diseases, such as CKD and ageing-associated complications. An integrated collaboration between nephrologists and experts from other fields, such as veterinarians, zoologists, biologists, anthropologists and ecologists, could introduce a novel approach for improving human health and help nephrologists to find novel treatment strategies for CKD.

    Full Text Available In the diffuse medical diseases of kidney, percutaneous renal biopsy is a valuable, safe and hazardless procedure. With the aid of this nearly new technique renal pathology, the natural history of renal diseases and the response of renal diseases to therapy, as well as the prognosis of renal disorders can be evaluated."nWe have analysed 210 percutaneous biopsies in Tehran. Complications were observed in 13% of cases, there is no mortality and no patient required drastic therapeutic intervention. Anuria, peri-renal colic and peri-renal hematoma were the only serious complications, which were seen in 4 patients, and were. readily controled with simple measures We obtained renal tissue in 95% cases of our patients and in 9 I% of them the tissue was adequate for c'ear diagnosis."nLike other authors, we believe that the procedure, when properly performed, can give a far more valuable informations about the patients without any realy dangerous risk.

  3. Comparative study of unilateral renal tubule function using 131I-o-hippuran and sup(99m)Tc-dimercaptosuccinic acid with regard to renal depth and excretion relations

    International Nuclear Information System (INIS)

    Moser, E.A.


    Good agreement was found between sonographic and nuclear renal depth data. In patients with undisturbed postrenal urodynamics, the data of unilateral renal clearance obtained by DMSA and OIH are in good agreement after depth correction. With OIH, the activity measured for unilateral congestion kidneys was higher than with DMSA. However, both methods may overestimate unilateral congestion kidneys. The OIH method should be favoured in nuclear renal diagnostics. In patients with mobile kidneys, the lower function calculated for the ptotic kidney can be evaluated only after depth correction. To reduce the radiation exposure, renal depth data required for depth correction should be determined by sonographic methods. The peak/scatter method of renal depth determination cannot be employed in practice in the 131 J hippurane test; in the sup(99m)Tc-DMSA test, sufficient agreement between peak/scatter quotient and renal depth is only obtained after background correction. The result does not warrant the tedious procedure. DMSA studies of the kidneys are appropriate in the following cases: 1. Emergency studies of unilateral renal function in cases of acute anuria due to postrenal stoppage. 2. Assessment of unilateral parenchymal function in patients with mobile kidneys if the ptotic kidney cannot be imaged by sonographic processes. 3. Search for extremely displaced renal tissue. 4. Unilateral renal function studies in patients with unilateral kidney diseases if the postrenal situation and the global renal function can be assessed by other methods. (orig./MG) [de

    P. Tamilmahan


    Full Text Available Aim: The aim of this study was to evaluate the simple tube cystostomy procedure for management of urethral obstruction cases in ruminants. Materials and Methods: Tube cystostomy was used to treat a total of 58 ruminants, which included 35 buffalo calves and 23 goats. Diagnosis of the disease was made with the history of anuria, clinical signs, and physical examinations. Physical parameters like heart rate, respiratory rate, rectal temperature dehydration status of animals by skin tenting test, and intraoperative findings were compared. Results: Young ruminants were most commonly affected and the mean age was 4-5 months in both species. Only male were considered for the study in which buffalo calves were not castrated but in goat's 73.91% animal were castrated and 34.7% not castrated. Rupture of bladder was more common in buffalo calves as compared to goats. The confirmed cases of obstructive urolithiasis were selected for tube cystostomy with Foley's catheter. Postoperatively all cases were administered with broad spectrum antibiotic, anti-inflammatory agent, and caliculolytic agents like ammonium chloride. Postoperative complications recorded only in 10 animals and remaining 48 animals had an uneventful recovery. Conclusion: Tube cystostomy is a simple and effective procedure particularly in intact urinary bladder, which can be adopted at field level.

  5. Ureteral stents increase risk of postoperative acute kidney injury following colorectal surgery. (United States)

    Hassinger, Taryn E; Mehaffey, J Hunter; Mullen, Matthew G; Michaels, Alex D; Elwood, Nathan R; Levi, Shoshana T; Hedrick, Traci L; Friel, Charles M


    Ureteral stents are commonly placed before colorectal resection to assist in identification of ureters and prevent injury. Acute kidney injury (AKI) is a common cause of morbidity and increased cost following colorectal surgery. Although previously associated with reflex anuria, prophylactic stents have not been found to increase AKI. We sought to determine the impact of ureteral stents on the incidence of AKI following colorectal surgery. All patients undergoing colon or rectal resection at a single institution between 2005 and 2015 were reviewed using American College of Surgeons National Surgical Quality Improvement Program dataset. AKI was defined as a rise in serum creatinine to ≥ 1.5 times the preoperative value. Univariate and multivariate regression analyses were performed to identify independent predictors of AKI. 2910 patients underwent colorectal resection. Prophylactic ureteral stents were placed in 129 patients (4.6%). Postoperative AKI occurred in 335 (11.5%) patients during their hospitalization. The stent group demonstrated increased AKI incidence (32.6% vs. 10.5%; p colorectal surgery including age, procedure duration, and ureteral stent placement. Prophylactic ureteral stents independently increased AKI risk when placed prior to colorectal surgery. These data demonstrate increased morbidity and hospital costs related to usage of stents in colorectal surgery, indicating that placement should be limited to patients with highest potential benefit.

  6. Extraperitoneal urine leak after renal transplantation: the role of radionuclide imaging and the value of accompanying SPECT/CT - a case report

    Son, Hongju; Heiba, Sherif; Kostakoglu, Lale; Machac, Josef


    The differentiation of the nature of a fluid collection as a complication of kidney transplantation is important for management and treatment planning. Early and delayed radionuclide renography can play an important role in the evaluation of a urine leak. However, it is sometimes limited in the evaluation of the exact location and extent of a urine leak. A 71-year-old male who had sudden anuria, scrotal swelling and elevated creatinine level after cadaveric renal transplantation performed Tc-99 m MAG3 renography to evaluate the renal function, followed by an ultrasound which was unremarkable. An extensive urine leak was evident on the planar images. However, an exact location of the urine leak was unknown. Accompanying SPECT/CT images confirmed a urine leak extending from the lower aspect of the transplant kidney to the floor of the pelvic cavity, presacral region and the scrotum via right inguinal canal as well as to the right abdominal wall. Renal scintigraphy is very useful to detect a urine leak after renal transplantation. However, planar imaging is sometimes limited in evaluating the anatomical location and extent of a urine leak accurately. In that case accompanying SPECT/CT images are very helpful and valuable to evaluate the anatomical relationships exactly

  7. Kidney transplantation from donors with rhabdomyolysis and acute renal failure. (United States)

    Chen, Chuan-Bao; Zheng, Yi-Tao; Zhou, Jian; Han, Ming; Wang, Xiao-Ping; Yuan, Xiao-Peng; Wang, Chang-Xi; He, Xiao-Shun


    Rhabdomyolysis in deceased donors usually causes acute renal failure (ARF), which may be considered a contraindication for kidney transplantation. From January 2012 to December 2016, 30 kidneys from 15 deceased donors with severe rhabdomyolysis and ARF were accepted for transplantation at our center. The peak serum creatinine (SCr) kinase, myoglobin, and SCr of the these donors were 15 569±8597 U/L, 37 092±42 100 μg/L, and 422±167 μmol/L, respectively. Two donors received continuous renal replacement therapy due to anuria. Six kidneys exhibited a discolored appearance (from brown to glossy black) due to myoglobin casts. The kidney transplant results from the donors with rhabdomyolysis donors were compared with those of 90 renal grafts from standard criteria donors (SCD). The estimated glomerular filtration rate at 2 years was similar between kidney transplants from donors with rhabdomyolysis and SCD (70.3±14.6 mL/min/1.73 m 2 vs 72.3±15.1 mL/min/1.73 m 2 ). We conclude that excellent graft function can be achieved from kidneys donors with ARF caused by rhabdomyolysis. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Mastro-Martínez, Ignacio; Montes-Arjona, Ana María; Escudero-Lirio, Margarita; Hernández-García, Bárbara; Fernández-Cantalejo Padial, José


    Rhabdomyolysis is a rare paediatric condition. The case is presented of a patient in whom this developed secondary to severe hypernatraemic dehydration following acute diarrhoea. Infant 11 months of age who presented with vomiting, fever, diarrhoea and anuria for 15 hours. Parents reported adequate preparation of artificial formula and oral rehydration solution. He was admitted with malaise, severe dehydration signs and symptoms, cyanosis, and low reactivity. The laboratory tests highlighted severe metabolic acidosis, hypernatraemia and pre-renal kidney failure (Sodium [Na] plasma 181 mEq/L, urine density> 1030). He was managed in Intensive Care Unit with gradual clinical and renal function improvement. On the third day, slight axial hypotonia and elevated cell lysis enzymes (creatine phosphokinase 75,076 IU/L) were observed, interpreted as rhabdomyolysis. He was treated with intravenous rehydration up to 1.5 times the basal requirements, and he showed a good clinical and biochemical response, being discharged 12 days after admission without motor sequelae. Severe hypernatraemia is described as a rare cause of rhabdomyolysis and renal failure. In critically ill patients, it is important to have a high index of suspicion for rhabdomyolysis and performing serial determinations of creatine phosphokinase for early detection and treatment.

  9. The clinician's guide to diagnostic imaging: Cost-effective pathways. Second edition

    International Nuclear Information System (INIS)

    Grossman, Z.D.; Chew, F.S.; Ellis, D.A.; Brigham, S.C.


    The authors developed a cost-effective approach to imaging studies, based on initial selection of an exam that best addresses the specific clinical problem and obviates the need for additional diagnostic tests. Tightly reasoned arguments compare available imaging options with respect to diagnostic yield, feasibility, risk, and cost. To aid the clinician in making cost comparisons, each paper of the Second Edition lists the dollar cost of relevant imaging studies. The Second Edition has been thoroughly revised to reflect the important advances in diagnostic imaging of the past three years, highlighting CT's expanding role in thoracic and abdominal problems, magnetic resonance imaging as a spectacular diagnostic tool for the central nervous system, and the clinical application of many newly-developed radiopharmaceuticals. New chapters cover breast cancer screening, acute spinal trauma, search for primary cancer of unknown origin, acute anuria, blunt chest trauma, new onset seizures, and spinal cord compression from metastases. Other papers have been rewritten for greater clarity and to incorporate new techniques, like dipyridamole stress testing. A glossary and an introduction define and explain the capabilities and limitations of current techniques

    Sugarcane (Saccharum officinarum Linn.) is an important perennial grass of Poaceae family, indigenous to tropical South Asia and Southeast Asia. It is cultivated worldwide due to the economical and medicinal value of its high yielding products. Sugarcane juice is well known as a raw material for the production of refined sugar and its wax is considered as a potential substitute for the expensive carnauba wax, which is of cosmetic and pharmaceutical interest. Refined sugar is the primary product of sugarcane juice, but during its processing, various other valuable products are also obtained in an unrefined form, such as, brown sugar, molasses, and jaggery. Sugarcane juice is widely used in India in the treatment of jaundice, hemorrhage, dysuria, anuria, and other urinary diseases. Herein, we have summarized the different phytoconstituents and health benefits of sugarcane and its valuable products. The phytochemistry of sugarcane wax (obtained from the leaves and stalks of sugarcane), leaves, juice, and its products has revealed the presence of various fatty acid, alcohol, phytosterols, higher terpenoids, flavonoids, -O- and -C-glycosides, and phenolic acids. The future prospective of some of the sugarcane products has been discussed, which needs a phytopharmacological study and has a great potential to be a valuable medicinal product.

  11. Tocilizumab for uncontrollable systemic inflammatory response syndrome complicating adult-onset Still disease (United States)

    Abstract Rationale: Adult-onset Still disease (AOSD) is a rare systemic inflammatory disease of unknown etiology characterized by evanescent salmon-pink rash, fever spikes, arthralgia, and lymphadenopathy. AOSD usually has a good prognosis, but it can sometimes be fatal, especially when it is complicated by systemic inflammatory response syndrome (SIRS) and multiple organ failure. Patient concerns: A previously healthy 26-year-old woman was referred to our hospital for persistent high fever and mild systemic edema. Five days later, the patient presented with dyspnea, hypotension, and anuria. Anasarca developed with massive pleural effusion, ascites, and systemic edema, resulting in an increase of 47 kg in body weight. Diagnoses: The patient was diagnosed as AOSD after infection, malignancy, hematologic disorders, and other autoimmune diseases were excluded. Interventions: We administered tocilizumab, an IL-6 receptor inhibitor, intravenously in addition to cyclosporine, prednisolone, plasma exchange, and continuous hemodiafiltration. Outcomes: The patient's systemic condition improved. After stabilization by all medications, the patient was managed and responded to tocilizumab alone. To the best of our knowledge, this was the first case of severe SIRS complicating AOSD that was successfully treated with an anti- IL-6 receptor antibody. Lessons: SIRS should not be overlooked in a patient with steroid-resistant AOSD and edema. Inhibitors of the IL-6 receptor can be used safely and effectively to control AOSD complicated with severe SIRS. PMID:28723802

  12. Gastrointestinal Bleeding and Diffuse Skin Thickening as Kaposi Sarcoma Clinical Presentation

    Directory of Open Access Journals (Sweden)

    Sara Querido


    Full Text Available A 56-year-old African patient received a kidney from a deceased donor with 4 HLA mismatches in April 2013. He received immunosuppression with basiliximab, tacrolimus, mycophenolate mofetil, and prednisone. Immediate diuresis and a good allograft function were soon observed. Six months later, the serum creatinine level increased to 2.6 mg/dL. A renal allograft biopsy revealed interstitial fibrosis and tubular atrophy grade II. Toxicity of calcineurin inhibitor was assumed and, after a switch for everolimus, renal function improved. However, since March 2014, renal function progressively deteriorated. A second allograft biopsy showed no new lesions. Two months later, the patient was admitted due to anuria, haematochezia with anaemia, requiring 5 units of packed red blood cells, and diffuse skin thickening. Colonoscopy showed haemorrhagic patches in the colon and the rectum; histology diagnosis was Kaposi sarcoma (KS. A skin biopsy revealed cutaneous involvement of KS. Rapid clinical deterioration culminated in death in June 2014. This case is unusual as less than 20 cases of KS with gross gastrointestinal bleeding have been reported and only 6 cases had the referred bleeding originating in the lower gastrointestinal tract. So, KS should be considered in differential diagnosis of gastrointestinal bleeding in some kidney transplant patients.

    Based on experience gained from more than 1600 patients with proved or suspected kidney diseases and on results on extended studies with dogs, sequential scintigraphy was performed after renal transplantation in dogs. After intravenous injection of 500 {mu}Ci. {sup 131}I-Hippuran scintiphotos were taken during the first minute with an exposure time of 15 sec each and thereafter with an exposure of 2 min up to at least 16 min.. Several examinations were evaluated digitally. 26 examinations were performed on 11 dogs with homotransplanted kidneys. Immediately after transplantation the renal function was almost normal arid the bladder was filled in due time. At the beginning of rejection the initial uptake of radioactive Hippuran was reduced. The intrarenal transport became delayed; probably the renal extraction rate decreased. Corresponding to the development of an oedema in the transplant the uptake area increased in size. In cases of thrombosis of the main artery there was no evidence of any uptake of radioactivity in the transplant. Similar results were obtained in 41 examinations on 15 persons. Patients with postoperative anuria due to acute tubular necrosis showed still some uptake of radioactivity contrary to those with thrombosis of the renal artery, where no uptake was found. In cases of rejection the most frequent signs were a reduced initial uptake and a delayed intrarenal transport of radioactive Hippuran. Infarction could be detected by a reduced uptake in distinct areas of the transplant. (author)

  14. Acute aortic dissection: be aware of misdiagnosis

    Directory of Open Access Journals (Sweden)

    Asteri Theodora


    Full Text Available Abstract Background Acute aortic dissection (AAD is a life-threatening condition requiring immediate assessment and therapy. A patient suffering from AAD often presents with an insignificant or irrelevant medical history, giving rise to possible misdiagnosis. The aim of this retrospective study is to address the problem of misdiagnosing AD and the different imaging studies used. Methods From January 2000 to December 2004, 49 patients (41 men and 8 women, aged from 18–75 years old presented to the Emergency Department of our hospital for different reasons and finally diagnosed with AAD. Fifteen of those patients suffered from arterial hypertension, one from giant cell arteritis and another patient from Marfan's syndrome. The diagnosis of AAD was made by chest X-ray, contrast enhanced computed tomography (CT, transthoracic echocardiography (TTE and coronary angiography. Results Initial misdiagnosis occurred in fifteen patients (31% later found to be suffering from AAD. The misdiagnosis was myocardial infarction in 12 patients and cerebral infarction in another three patients. Conclusion Aortic dissection may present with a variety of clinical manifestations, like syncope, chest pain, anuria, pulse deficits, abdominal pain, back pain, or acute congestive heart failure. Nearly a third of the patients found to be suffering from AD, were initially otherwise diagnosed. Key in the management of acute aortic dissection is to maintain a high level of suspicion for this diagnosis.

    Andrea Babic-Erceg


    Full Text Available A 25-years old man from Zagreb, Croatia, was admitted to the University Hospital for Infectious Diseases four days after the onset of symptoms such as fever, intense pain in the calves and anuria. The patient owned a rabbit and, before the onset of the disease, repaired some rubber pipes damaged by rodents. At admission, he had a severe clinical picture with fever, hypotension, jaundice, immobility, and pain in leg muscles. Treatment with ceftriaxone was initiated in combination with volume restitution. Renal failure soon ensued. Consequently continuous venovenous hemodiaphiltration therapy was performed. Due to acute respiratory distress syndrome, the patient was mechanically ventilated. The patient’s condition gradually improved and he recovered fully from multi-organ failure. Diagnosis was confirmed by a microscopic agglutination test (MAT covering 15 leptospira serovars and real-time polymerase-chain reaction (PCR. The first serum sample taken on day 6 tested negative for leptospira, while PCR showed positive results for leptospiral DNA. The second serum sample taken on day 13 tested positive for serovar Canicola serogroup Canicola, serovar Patoc, serovar Grippotyphosa serogroup Grippotyphosa and serovar Tarassovi serogroup Tarassovi (titre 4000, 4000, 1000 and 2000, respectively, while PCR was negative. This report highlights the benefits of combining MAT and PCR methods in early diagnosis of leptospirosis.

    We report on a 3-year-old girl with respiratory syncytial virus (RSV) encephalitis manifested by disturbance of consciousness, conjugate eye deviation, anuria, truncal ataxia and intention tremor. T2-weighted magnetic resonance imaging (MRI) showed hyperintense areas in the cerebellar cortex. No lesion was detected in the cerebral cortex, pons or spinal cord. The hyperintense areas in the cerebellar cortex diminished with recovery from the clinical manifestations and had resolved 2 months after onset. The MRI lesions in the cerebellum were considered to be due to oedema. SPECT and positron emission tomography (PET), performed 3 months after onset, disclosed areas of hypoperfusion and hypometabolism at the same sites. One year after onset, MRI showed mild atrophy of the cerebellum. Hypoperfusion on SPECT and hypometabolism on PET remained. Neuroimaging showed that ataxia and tremor in this case were the result of cerebellitis. The patient has no neurological deficit except for mild truncal ataxia. This patient is a rare example of RSV encephalitis. (orig.)

  18. A case of primary mucosa-associated lymphoid tissue lymphoma of the vagina. (United States)

    Yoshinaga, Kousuke; Akahira, Jun-Ichi; Niikura, Hitoshi; Ito, Kiyoshi; Moriya, Takuya; Murakami, Takashi; Kameoka, Jun-Ichi; Ichinohasama, Ryo; Okamura, Kunihiro; Yaegashi, Nobuo


    We report the first case of primary mucosa-associated lymphoid tissue (MALT) lymphoma of the vagina, the diagnosis of which is supported by genetic and immunophenotypic studies. A 65-year-old, para 2 woman presented to our hospital in July 1997 with a history of prolonged vaginal discharge. Although cytologic examination suggested possible malignancy, a biopsy of the vaginal wall was diagnosed as chronic inflammation. In June 2000, she underwent gynecologic examination because of anuria. Excisional biopsy revealed subepithelial infiltration of atypical lymphoid cells that stained for CD20, CD79a, and BCL-2; stained weakly for IgM; and did not stain for CD3, CD5, CD7, CD10, CD56, CD23, and IgD, suggesting marginal zone B-cell lineage. Monoclonality was detected by Southern blot analysis, and this patient was finally diagnosed as having primary MALT lymphoma of the vagina. She received 3 cycles of chemotherapy (THP-COP) and concurrent radiation to the whole pelvis. The patient is alive and well 40 months after treatment. Because the vagina is one of the mucosa-associated tissues, MALT lymphoma, though rare, must be included in the differential diagnosis of the vaginal neoplasms.

  19. A Review of the Surgical Management of Perineal Hernias in Dogs. (United States)

    Gill, Sukhjit Singh; Barstad, Robert D


    Perineal hernia refers to the failure of the muscular pelvic diaphragm to support the rectal wall, resulting in herniation of pelvic and, occasionally, abdominal viscera into the subcutaneous perineal region. The proposed causes of pelvic diaphragm weakness include tenesmus associated with chronic prostatic disease or constipation, myopathy, rectal abnormalities, and gonadal hormonal imbalances. The most common presentation of perineal hernia in dogs is a unilateral or bilateral nonpainful swelling of the perineum. Clinical signs do occur, but not always. Clinical signs may include constipation, obstipation, dyschezia, tenesmus, rectal prolapse, stranguria, or anuria. The definitive diagnosis of perineal hernia is based on clinical signs and findings of weak pelvic diaphragm musculature during a digital rectal examination. In dogs, perineal hernias are mostly treated by surgical intervention. Appositional herniorrhaphy is sometimes difficult to perform as the levator ani and coccygeus muscles are atrophied and unsuitable for use. Internal obturator muscle transposition is the most commonly used technique. Additional techniques include superficial gluteal and semitendinosus muscle transposition, in addition to the use of synthetic implants and biomaterials. Pexy techniques may be used to prevent rectal prolapse and bladder and prostate gland displacement. Postoperative care involves analgesics, antibiotics, a low-residue diet, and stool softeners.

  20. Role of radiopharmaceutical renal function studies in the medical surveillance of patients with transplanted kidneys

    International Nuclear Information System (INIS)

    Ernst, S.


    In a study group of 35 patients having received a total of 37 kidneys 204 renal function scintiscans were obtained following administration of 99mTc DTPA and analysed with regard to the question as to whether radiopharmaceutical investigations using a gamma camera are a useful auxiliary tool to detect and diagnose functional disorders in the transplant that occur soon after surgery. In all of 13 patients showing complications in the form of prolonged anuria or oliguria during a period of up to 14 days following surgical intervention, the renal function scintiscans either permitted as firm diagnosis to be established or revealed conclusive findings that pointed to the necessity of further specific tests. Long-term follow-up studies carried out in 33 individuals failed or were slow to reveal acute or chronic rejection processes in one quarter of the patients, whereas the renal function scintiscans gave the earliest warning of functional disorders, unfavourable developments and complications in another quarter of patients; in the remaining part, the test results were in keeping with the clinical findings. Renal function scintiscans were thus judged to be a valuable diagnostic tool to ascertain and identify disorders occurring soon after surgery as well as to detect the early signs of functional disorders in the transplant during long-term follow-up studies. In view of the fact, however, that the sensitivity of the method in this field of application only is of the order of 75%, further research work appears to be required here. (TRV) [de

  1. Syndrome of hypoplasic left ventricle, Description of a clinical case with survival after carrying out of Norwood technique

    International Nuclear Information System (INIS)

    Velasco B, Ana M; Lince V, Rafael; Zapata S, Jorge A and others


    A clinical case of a 72 hours newborn patient admitted to the pediatric intensive care unit for reduced cardiac output syndrome showing anuria, metabolic acidosis and respiratory distress, is reported. Mechanical ventilation, inotropic support and continuous prostaglandin e1 infusion were initiated. The echocardiogram showed hypoplasia of the left ventricle. The Norwood procedure stage i under extracorporeal circulation with deep hypothermia and circulatory arrest, was performed at the 6th day of life. During the early postoperative period, the patient developed hypoxaemia and pulmonary hypertension, which improved with controlled hyperventilation and vasodilatation therapy. Other complications were clinical sepsis and abstinence syndrome, which resolved with medical management. The patient was extubated on the sixth postoperative day. Subsequent echocardiograms showed tricuspid valve regurgitation, right ventricular dysfunction with dilation and an organized thrombus in the left atrium. These improved with diuretics, dopamine, milrinone and heparin. The patient was discharged after 32 days of the surgery without signs of congestive heart failure. This case is important, given the high mortality rate of this pathology. The Norwood procedure proved to be a palliative strategy versus the ortotopic cardiac transplant in newborns, because of the difficulty in finding donators at this age and the immunosuppressive therapy complications. This represents a great advance in the Colombian pediatric cardiology because until recent years these patients did not have any other surgical alternative

    Objective: To investigate the significance of renal arterial embolization nephrectomy for treating post-transplanted renal failure. Methods: 15 cases of post-transplanted renal failure received renal arterial embolization. The post-procedural efficacies were followed up for about 6 months to 4 years. Results: Among the 15 cases, 11 showed blood pressure decreasing to normal level, 3 with reduction of the drug dose for anti-hypertension and 1 of no response. In addition, 12 suffered from postprocedural anuria, and 3 with obvious hypourocrinia associated with significant decrease of proteinuia; 5 with positive lymphcytic population response antigen (PRA > 20%), but turning negative with 3 of them after 3 weeks. All the transplanted kidneys revealed different degrees of atrophy but 4 of them obtained chances of successful retransplantation 3- 6 months after the procedure, 3 of them with follow up of 1-3 years were being well. Conclusions: Renal arterial embolization is a safe, efficient measure for treating post-transplanted renal failure with obvious decrease of correlative clinical symptoms and providing conditions for renal retransplantation.

    Full Text Available Aim: The present work was designed to study the incidence of obstructive urolithiasis and to apply comparative diagnosis to urine retention cases. Materials and Methods: A total of 78 non-castrated buffalo calves aging 3-11 months were included in this study, 68 calves were admitted to the Veterinary Teaching Hospital, Zagazig University, Egypt, during the study period with a history of anuria, and they were classified into three groups; intact bladder group (19 calves, uroperitoneum group (45 calves, and ruptured urethra group (4 calves. 10 apparently healthy calves were used for comparison. On the basis of history, clinical, laboratory, and ultrasonographic findings diagnosis was achieved. Results: There was a marked increase in the incidence of obstructive urolithiasis in winter season, especially in winter months of 2016. Calves within the age of 3-4 months and 6-8 months were mostly affected. Inappetence to anorexia, restlessness or depression, and abdominal distension were the most observed signs in the diseased calves. Laboratory findings revealed hemoconcentration and a significant increase in blood urea nitrogen and serum creatinine levels in all diseased groups. Hyperproteinemia, hypocalcemia, and hyperphosphatemia with electrolytes imbalance were recorded in the uroperitoneum group. Ultrasonographically, distended urinary bladder with distal acoustic enhancement revealed obstructive urolithiasis with intact bladder while anechoic fluid in abdominal cavity indicates uroperitoneum. Conclusion: On the basis of all findings, calves with intact bladder were in superior condition than those with a ruptured urethra and both were better than those with uroperitoneum.

  4. Nitrite-induced acute kidney injury with secondary hyperparathyroidism: Case report and literature review. (United States)

    Peng, Tao; Hu, Zhao; Yang, Xiangdong; Gao, Yanxia; Ma, Chengjun


    Acute kidney injury (AKI) with hyperparathyroidism caused by nitrite was rare, and renal function and parathyroid hormone (PTH) decreased to normal range after therapy. Acute kidney injury was diagnosed in a 40-year-old male with hyperparathyroidism and cyanosis of his hands and both forearms. The patient ate some recently pickled vegetables, and he experienced nausea, vomiting and diarrhoea without oliguria or anuria; Additionally, his hands and both forearms had a typical blue ash appearance. After admission, the laboratory findings indicated theincreasing serum creatinine (Scr) and parathyroid hormone (PTH). He was diagnosed as acute kidney injury with hyperparathyroidism caused by nitrite. The patient stopped eating the pickled vegetables and was given rehydration, added calories and other supportive therapy without any glucocorticoids. According to his clinical manifestations, laboratory findings and imaging results, the patient was diagnosed with acute kidney injury with secondary hyperparathyroidism. He was given symptomatic supportive care therapy. After one week, the serum creatinine, parathyroid hormone (PTH), hypercalcemia, hyperphosphatemia, proteinuria, and urine red blood cell values decreased to normal range. Nitrite-induced acute kidney injury with secondary hyperparathyroidism was relatively rare. After therapy, the function of the kidney and parathyroid returned to normal. This case suggests that detailed collection of medical history, physical examination and correct symptomatic treatment is very important.

    Mohsen Akhavan Sepahi


    Full Text Available Acute glomerulonephritis (AGN is a type of renal disease which indicates the inflammation of glomerulus and nephrons. This study was carried on 94 children, <15 years old with the diagnosis of AGN who were admitted to Qom and Yazd's hospitals between 2000 and 2006. Data were collected using hospital records on admission, progression notes and outpatient follow up. Among 94 patients, 55.3% were male and 44.6% were female. Mean age of patients was 8.2±2.7 years old. Acute post streptococcal glomerulonephritis (APSGN was reported in 92.5%, membranoproliferative glomerulonephritis in 4.2%, hemolytic uremic syndrome in 2.1% and IgA nephropathy in 1.06%. There was no significant differences between GN types and gender (P=0.54. Clinical manifestation included edema in 68.8%, oliguria in 36.3%, gross hematuria in 69.1%, HTN in 61.7% and anuria in 1.06%. Microscopic hematuria was detected in all patients. In the time of follow up none of patients had hypertension, 3.1% had proteinuria and 6.3% had microscopic hematuria. APSGN is the most common causes of AGN in Qom and Yazd's children. Early diagnosis and treatment of APSGN may protect children from long term morbidity and mortality and improve quality of life.

  6. Hypertonic saline solution and high-dose furosemide infusion in cardiorenal syndrome: our experience

    Directory of Open Access Journals (Sweden)

    Francesco Ventrella


    Full Text Available Introduction Heart failure is frequently complicated by renal failure, and this association is a negative prognostic factor. These patients sometimes present oligo-/anuria and resistance to high-dose furosemide, a condition referred to as the cardiorenal syndrome (CRS. Acute or chronic reductions in left ventricular function result in decreased blood flow, with reduction of renal perfusion and activation of several neurohormonal systems, which cause resistance to diuretic therapy. This condition often requires ultrafiltration, which is an effective, but invasive and expensive procedure. Infusions of hypertonic saline solution (HSS and high-dose furosemide can be an effective alternative. Materials and methods From November 2009 through May 2010, our team treated 20 patients with CRS and resistance to iv boluses of high-dose furosemide. These patients were treated with small-volume (150-250 mL infusions of HSS (NaCl 1.57 – 4.5%, depending on serum Na values and high-dose furosemide twice a day. The aim of this treatment is to modify renal hemodynamics and the water-saline balance in the kidney by counteracting the extracellular fluid accumulation and eliminating symptoms of congestion. Results In 18 patients (90%, urine output was restored and renal function improved during the first hours of treatment. Clinical improvement was evident from the first day of therapy, and there were no adverse events. Two patients (10% did not respond to the treatment: one (who had been in critical condition since admission died; the other required regular sessions of ultrafiltration. Conclusions HSS combined with high-dose furosemide is a safe, effective, low-cost approach to the treatment of CRS that is resistant to diuretic therapy.

  7. Continuous hemofiltration dose calculation in a newborn patient with congenital heart disease and preoperative renal failure. (United States)

    Ricci, Z; Polito, A; Giorni, C; Di Chiara, L; Ronco, C; Picardo, S


    To report a case of a newborn patient with renal failure due to polycystic kidneys requiring renal replacement therapy, and total anomalous pulmonary venous return requiring major cardiosurgical intervention. Pediatric cardiosurgery operatory room and pediatric cardiologic intensive care. A 6-day-old newborn child weighing 3.1 kg. Renal function (creatinine value and urine output) was monitored during the course of the operation and intraoperative renal replacement therapy was not initiated. Serum creatinine concentration decreased from 4.4 to 3 mg/dL at cardiopulmonary bypass (CPB) start and to 1.5 at the end of surgery: the creatinine decrease was provided by the dilutional effect of CPB priming and the infusion of fresh blood from transfusions together with an adequate filtration rate (800 m/L in about 120 minutes). After the operation, extracorporeal membrane oxygenation (ECMO) for ventricular dysfunction and continuous hemofiltration for anuria refractory to medical therapy were prescribed. The hemofiltration machine was set in parallel with the ECMO machine at a blood flow rate of 60 ml/min and a predilution replacement solution infusion of 600 ml/h (4.5 ml/min of creatinine clearance once adjusted on extracorporeal circuits; 3000 mL/m2 hemofiltration): after a single hemofiltration session lasting 96 hours, serum creatinine reached optimal steady state levels around 0.5 mg/dL on postoperative day 2 and 3. Administration of intraoperative continuous hemofiltration is not mandatory in the case of a 3-kg newborn patient with established renal failure needing major cardiosurgery: hemodilution secondary to CPB, transfusion of hemoderivates, and optimal UF rate appear to be effective methods for achieving solute removal. If postoperative continuous hemofiltration is started, however, a "dialytic dose" of 4.5 ml/min allows an adequate creatinine clearance, quick achievement of a steady state of serum creatinine concentration and an eventual acceptable rate of

  8. [Lithiasis of the distal ureter: ESWL or URS]. (United States)

    González Enguita, C; Sánchez Gómez, J; Rodríguez-Miñon Cifuentes, J L; Cabrera Pérez, J; Calahorra Fernández, F J; García Cardoso, J; García de la Peña, E; Vela Navarrete, R


    A nephritic colic is the clinical picture that evidences the presence of ureteral stones, the natural evolution being their spontaneous passing. Stones in the distal ureter are self-eliminated in about 71-80% cases. The adoption of a "watchful wait" involves an uncertain occupational and medical evolution since, although in some cases the stones will pass with no problems, in other instances they can result in severe, life threatening situations for the patient's health (intractable pain, anuria or sepsis). When a decision is made to treat the condition, there are two choices available: "in situ" SWEL (extracorporeal lithotrity), or URS (ureterorenoscopy), long-standing conflicting techniques each with its own advantages and disadvantages, which should now be considered complementary. SWEL's major disadvantage is the number of repetitions required and the long wait, sometimes even months, until the last fragment is passed. The greater strength of URS is that it can be resolutive in just one episode (95% cases), thus avoiding the obstruction problems that can arise after SWEL. In the Lithiasis-Lithotrity Unit of FJD, SWEL is the first therapeutical option for the treatment of stones in the distal ureter. SWEL and URS are equally likely to be performed although SWEL is the initial choice for efficiency reasons that are explained. We achieve 93.6% positive results with a 1.82% re-SWEL rate (retreatment), 0.60 coefficient of efficiency (EQ) and 0.69 modified coefficient of efficiency (EQM) (Chart). No serious complications were recorded. Morbidity is variable with little clinical significance. Distal ureter lithiasis can be treated with either URS and SWEL, both considered "different and complementary". The choice in each particular case and within each hospital will depend on availability of means to perform one or the other, equipment's efficiency, skill of the urologist, patient's preference and cost of each treatment.

  9. Suppressed bone remodeling in black bears conserves energy and bone mass during hibernation. (United States)

    McGee-Lawrence, Meghan; Buckendahl, Patricia; Carpenter, Caren; Henriksen, Kim; Vaughan, Michael; Donahue, Seth


    Decreased physical activity in mammals increases bone turnover and uncouples bone formation from bone resorption, leading to hypercalcemia, hypercalcuria, bone loss and increased fracture risk. Black bears, however, are physically inactive for up to 6 months annually during hibernation without losing cortical or trabecular bone mass. Bears have been shown to preserve trabecular bone volume and architectural parameters and cortical bone strength, porosity and geometrical properties during hibernation. The mechanisms that prevent disuse osteoporosis in bears are unclear as previous studies using histological and serum markers of bone remodeling show conflicting results. However, previous studies used serum markers of bone remodeling that are known to accumulate with decreased renal function, which bears have during hibernation. Therefore, we measured serum bone remodeling markers (BSALP and TRACP) that do not accumulate with decreased renal function, in addition to the concentrations of serum calcium and hormones involved in regulating bone remodeling in hibernating and active bears. Bone resorption and formation markers were decreased during hibernation compared with when bears were physically active, and these findings were supported by histomorphometric analyses of bone biopsies. The serum concentration of cocaine and amphetamine regulated transcript (CART), a hormone known to reduce bone resorption, was 15-fold higher during hibernation. Serum calcium concentration was unchanged between hibernation and non-hibernation seasons. Suppressed and balanced bone resorption and formation in hibernating bears contributes to energy conservation, eucalcemia and the preservation of bone mass and strength, allowing bears to survive prolonged periods of extreme environmental conditions, nutritional deprivation and anuria. © 2015.

  10. Bilateral blindness secondary to optic nerve ischemia from severe amlodipine overdose: a case report. (United States)

    Kao, Raymond; Landry, Yves; Chick, Genevieve; Leung, Andrew


    Calcium channel blockers are commonly prescribed medications; calcium channel blocker overdose is becoming increasingly prevalent. The typical presentation of a calcium channel blocker overdose is hypotension and decreased level of consciousness. We describe a case of a calcium channel blocker overdose that led to bilateral cortical blindness, a presentation that has not previously been reported. A 49-year-old white woman with known bilateral early optic atrophy presented to our hospital with hypotension and obtundation following a known ingestion of 150 mg of amlodipine. She was transferred to our intensive care unit where she was intubated, mechanically ventilated, and required maximal vasopressor support (norepinephrine 40 mcg/minute, epinephrine 40 mcg/minute, and vasopressin 2.4 units/hour) along with intravenously administered crystalloid boluses. Despite these measures, she continued to deteriorate with persistent hypotension and tachycardia, as well as anuria. Intralipid emulsion therapy was subsequently administered to which no initial response was observed. A chest X-ray revealed diffuse pulmonary edema; intravenous diuresis as well as continuous renal replacement therapy was initiated. Following the initiation of continuous renal replacement therapy, her oxygen requirements as well as urine output began to improve, and 3 days later she was liberated from mechanical ventilation. Following extubation, she complained of new onset visual impairment, specifically seeing only red-green colors, but no objects. An ophthalmologic examination revealed that this was due to bilateral optic atrophy from prolonged hypotension during the first 24 hours after the overdose. Persistent hypotension in the setting of a calcium channel blocker overdose can lead to worsening optic atrophy resulting in bilateral cortical blindness.

    Objective: To describe the clinical spectrum and outcome of patients presenting to a tertiary care kidney center, developing acute kidney injury (AKI) after snake-bite. Study Design: An observational study. Place and Duration of Study: Nephrology Department, Sindh Institute of Urology and Transplantation (SIUT), Karachi, from January 1990 to December 2014. Methodology: All patients coming to SIUT identified as having AKI after snake-bite during the study period were included. AKI was defined according to RIFLE criteria with sudden rise in creatinine or decline in urine output or both. Demographics, clinical presentation, laboratory profile, and final outcome was noted. Result: During the studied period, 115 cases of AKI, secondary to snake-bite, were registered at this institution. Median age of patients was 35.92 ±15.04 (range: 6 - 70) years and male to female ratio was 1.6:1. Time from bite and referral to this hospital ranged from 2 to 28 days (mean: 8.77 ±5.58 days). Oligo-anuria was the most common presentation, being found in 98 (93.90 percentage) patients. Bleeding diathesis was reported in 75 (65.21 percentage) patients on presentation. All patients had normal sized, non-obstructed kidneys on ultrasonography, with no previous comorbids. Renal replacement therapy (RRT) was required in 106 (92.17 percentage) patients. Complete recovery was seen in 59 (51.30 percentage), while 15 (13.04 percentage) patients expired during acute phase of illness, 4 (3.47 percentage) developed CKD, 11 (9.56 percentage) required dialysis beyond 90 days, and 26 (22.60 percentage) were lost to long-term follow-up. Conclusion: Snake-bite, leading to multiple complications including renal failure and death, is a major health issue in tropical countries. Late referral of these patients to specialized centres Result in undesirable outcome. (author)

  13. Recipient Related Prognostic Factors for Graft Survival after Kidney Transplantation. A Single Center Experience

    Directory of Open Access Journals (Sweden)

    Alina Daciana ELEC


    Full Text Available Background and Aim. Advanced chronic kidney disease (CKD severely impairs life expectancy and quality of life in affected patients. Considering its benefits, renal transplantation currently represents the optimal treatment solution for end stage kidney disease patients. Pre-transplant assessment aims to maximize the graft and patient survival by identifying potential factors influencing the post-transplant outcome. The aim of this study has been to analyze recipient related prognostic factors bearing an impact on graft survival. Material and Methods. We analyzed the graft outcomes of 426 renal transplantations performed at the Clinical Institute of Urology and Renal Transplantation of Cluj-Napoca, between January 2004 and December 2008. Variables related to recipient and to potential donor/recipient prognostic factors were studied using univariate and multivariate analysis. Results. Graft survivals at 1, 3, 5 and 7 years were 94.01%, 88.37%, 82.51% and 78.10%, respectively. Chronic rejection (41.11% and death with a functioning graft (18.88% were the main causes of graft loss. In uni and multivariate analysis the recipient related variables found to influence the renal graft outcome were: peritoneal dialysis, pre transplant residual diuresis, grade I hypertension, severe iliac vessel atheromatosis, ischemic heart disease, stroke history, dyslipidemia and denutrition. The worst graft outcomes have been found for recipients on peritoneal dialysis, with anuria, hypotension, severe iliac atheromatosis, ischemic heart disease, stroke history, dyslipidemia and a poor nutritional status. Conclusion. The type of dialysis, the pre transplant residual diuresis, recipient arterial blood pressure, iliac vessel atheromatosis, ischemic heart disease, stroke history, dyslipidemia and denutrition significantly influence graft survival.

  14. [Clinical presentation of different severities of hemorrhagic fever with renal syndrome: how to recognise it]. (United States)

    Lausević, Mirjana; Lausević, Zeljko; Stojimirović, Biljana


    Besides viral serotype, HLA haplotype and cytokine genes polymorphism are associated with clinical presentation of hemorrhagic fever with renal syndrome. Since these analyses are unavailable in routine clinical practice, the aim of this study was to assess clinical, laboratory and radiographic findings associated with clinical presentation of disease severity. A total of 30 patients (27 men and 3 women), average age 40 +/- 14.9 years, treated for hemorrhagic fever with renal syndrome from January 1, 1999 to December 31, 2009 in Clinical Center of Serbia, were included in the study. Nine patients (30%) had mild, 14 (46.7%) moderate and 7 (23.3%) severe form of the disease; 24 (800%) recovered, 6 (20%) died in the acute phase of the illness, and 19 patients (63.3%) required hemodialysis. The average titer of antiviral antibodies in patients infected with Belgrade serotype virus were significantly higher in those with severe clinical presentation. Hypotension, anuria, macrohaematuria, pulmonary infiltration, pleural effusion, hepatomegalia and positive meningeal signs were more frequent in the patients with severe form of the disease. Statistically significant differences between groups with mild, moderate and severe clinical picture were found in serum total protein, albumin, calcium, glutamate pyruvate and glutamate oxaloacetate transaminase on admittance; serum creatinine and phosphorus concentration on day 14 and day 21; serum sodium and calciums on day 14; hemoglobine concentration on day 21. A statistically significant correlation was found between clinical presentation of the disease severity and platelet count, white blood cell count, hemoglobine concentration, serum calcium and serum transaminases on admittance. Multivariate analysis identified variables' combinations associated with clinical presentation of the disease. Our study confirmed that we can distinguish patients who will manifest different severities of the disease on the basis of careful

    Full Text Available BACKGROUND: Studies on risk factors of mortality in elderly patients with hemodialysis usually focus on comorbidities, nutrition, and inflammation. Discussion on the correlation between living environment and mortality of these patients is limited. METHODS: A total of 256 elderly hemodialysis patients participated in this 2-year prospective observational study. The subjects were divided into 2 subgroups based on whether they were living in Taipei Basin (n = 63 or not (n = 193. Demographic, hematological, nutritional, inflammatory, biochemical, and dialysis-related data were obtained for cross-sectional analysis. Causes of death and mortality rates were also analyzed for each subgroup. RESULTS: Patients in the basin group had a higher incidence of combined protein-energy wasting and inflammation than those in the around basin group. At the end of the 2-year follow-up, 68 patients had died. Univariate binary logistic regression analysis revealed that a very advanced age, basin group, serum albumin levels, serum creatinine levels, non-anuria, and the complications of stroke and CAD were associated with 2-year mortality. Meanwhile, log high-sensitivity C-reactive protein (hs-CRP levels were not associated with 2-year mortality. Multivariate Cox regression analysis revealed that basin group, serum albumin levels, and the complications of stroke and CAD were significant risk factors for 2-year mortality in these patients. CONCLUSION: The results of this study indicate that factors such as living in the Taipei Basin with higher air pollutant levels in elderly hemodialysis patients is associated with protein-energy wasting and inflammation, as well as 2-year mortality. These findings suggest that among this population, living environment is as important as comorbidities and nutrition. Furthermore, air pollution should be getting more attention especially in the overcrowding Basin topography.

    Jamal, A.; Ramzan, A.


    Objective: To identify the causes of acute renal failure (ARF) in pediatric population along with the identification of the age and gender most affected by the failure. Subjects and Methods: The study included children under the age of 12 years who presented with signs and symptoms suggestive of ARF (oliguria/anuria, vomiting, acidotic breathing etc.) along with raised blood urea nitrogen (BUN) serum creatinine and metabolic acidosis as shown by arterial blood gases (ABGs). Patients were divided into two group on the basis of age; group A consisting of 0-2 years and group B from >2 years. Patients presenting with transient pre-renal azotaemia were excluded from the study. After providing initial emergency cover, detailed history, physical examination and investigations were carried out according to a proforma specially designed to ascertain the cause of ARF. Patients were managed for ARF as per standard recommendations and investigations completed or repeated as and when required. Results: A total of 119 patients with ARF were admitted in the ward over a period of two years constituting 1.36% of the total admissions and 16.39% of the admissions due to renal pathology. Mean age of presentation was 4.5 years 16.7% of the patients under the age of 5 years. Male predominance was noted in all ages with an overall male to female ratio of 2.3:1. Most common cause leading to ARF in younger age group was found to be hemolytic uremic syndrome [25(54.34%)] followed by septicemia [7(15.21 %)]. In older patients renal calculus disease was the most common [22(30.13%)] underlying pathology followed by pre-existing, undiagnosed chronic renal failure [16(21.91 %)]. Conclusion: ARF is fairly cotton in children especially under the age of 5 years showing a male predominance. More than 90% of the cases can be prevented by improving primary health care and by early and prompt treatment of infections. (author)

    Full Text Available Most adults dying from falciparum malaria will die within 48 hours of their hospitalisation. An essential component of early supportive care is the rapid identification of patients at greatest risk. In resource-poor settings, where most patients with falciparum malaria are managed, decisions regarding patient care must frequently be made using clinical evaluation alone.We retrospectively analysed 4 studies of 1801 adults with severe falciparum malaria to determine whether the presence of simple clinical findings might assist patient triage.If present on admission, shock, oligo-anuria, hypo- or hyperglycaemia, an increased respiratory rate, a decreased Glasgow Coma Score and an absence of fever were independently predictive of death. The variables were used to construct a simple clinical algorithm. When applied to the 1801 patients, this algorithm's positive predictive value for survival to 48 hours was 99.4 (95% confidence interval (CI 97.8-99.9 and for survival to discharge 96.9% (95% CI 94.3-98.5. In the 712 patients receiving artesunate, the algorithm's positive predictive value for survival to 48 hours was 100% (95% CI 97.3-100 and to discharge was 98.5% (95% CI 94.8-99.8.Simple clinical findings are closely linked to the pathophysiology of severe falciparum malaria in adults. A basic algorithm employing these indices can facilitate the triage of patients in settings where intensive care services are limited. Patients classified as low-risk by this algorithm can be safely managed initially on a general ward whilst awaiting senior clinical review and laboratory data.

    Full Text Available We present the first report of a case of fibrillary glomerulonephritis (FGN associated with thrombotic microangiopathy (TMA and anti-glomerular basement membrane antibody (anti-GBM antibody. A 54-year-old man was admitted to our hospital for high fever and anuria. On the first hospital day, we initiated hemodialysis for renal dysfunction. Laboratory data revealed normocytic-normochromic anemia with schistocytes in the peripheral smear, thrombocytopenia, increased serum lactate dehydrogenase, decreased serum haptoglobin, and negative results for both direct and indirect Coombs tests. Based on these results, we diagnosed TMA. Assays conducted several days later indicated a disintegrin-like and metalloprotease with a thrombospondin motif 13 (ADAMTS13 activity of 31.6%, and ADAMTS13 inhibitors were negative. We started plasma exchange using fresh frozen plasma and steroid pulse therapy. Anti-GBM antibody was found to be positive. Renal biopsy showed FGN. Blood pressure rose on the 46th hospital day, and mild convulsions developed. Based on magnetic resonance imaging of the head, the patient was diagnosed with reversible posterior leukoencephalopathy syndrome. Hypertension persisted despite administration of multiple antihypertensive agents, and the patient experienced a sudden generalized seizure. Computed tomography of the head showed multiple cerebral hemorrhages. However, his blood pressure subsequently decreased and the platelet count increased. TMA remitted following 36 plasma exchange sessions, but renal function was not restored, and maintenance hemodialysis was continued. The patient was discharged on the 119th day of hospitalization. In conclusion, it was shown that TMA, FGN and anti-GBM antibody were closely related.

    Full Text Available Acute kidney injury (AKI is one of the most challenging and serious complications of pregnancy. We present our experience on the clinical profile and outcome of 57 patients with pregnancy-related AKI, of a total of 580 patients with AKI seen during the study period. This is a prospective single-center study in a civil hospital conducted from January to December 2010. The most common age group of the study patients was 20-25 years; 43.8% of the patients had received antenatal care. AKI was observed in the puerperium (n = 34, early pregnancy (n = 10 and late pregnancy (n = 13. The cause of AKI included puerperal sepsis (63.1%, pregnancy-induced hypertension (PIH (33.33%, post-abortion (22.80%, ante-partum hemorrhage (APH (14% and post-partum hemorrhage (PPH (8%. Complete, partial and no renal recovery was observed in 52.64%, 21.05% and 26.31% of the patients, respectively. Low platelet count and plasma fibrinogen and high bilirubin, D-dimer and activated partial throm-boplastin time were observed more commonly in patients with partial recovery. Of the 57 patients, 50 received hemodialysis, three received peritoneal dialysis and seven patients were managed conserva-tively. A total of 13 patients developed cortical necrosis that was associated with sepsis in six, PPH and pre-eclampsia/eclampsia in three patients each and APH in one. Nine patients died, and the cause of death was septicemia in four, pre-eclampsia in three and APH and PPH in one patient each. In our study, puerperal sepsis was the most common etiological factor for pregnancy-related AKI. Prolonged oliguria or anuria were bad prognostic factors for renal recovery. Sepsis, thrombocytopenia, disseminated intra-vascular coagulation and liver involvement were associated with increased mortality.

    Studies on risk factors of mortality in elderly patients with hemodialysis usually focus on comorbidities, nutrition, and inflammation. Discussion on the correlation between living environment and mortality of these patients is limited. A total of 256 elderly hemodialysis patients participated in this 2-year prospective observational study. The subjects were divided into 2 subgroups based on whether they were living in Taipei Basin (n = 63) or not (n = 193). Demographic, hematological, nutritional, inflammatory, biochemical, and dialysis-related data were obtained for cross-sectional analysis. Causes of death and mortality rates were also analyzed for each subgroup. Patients in the basin group had a higher incidence of combined protein-energy wasting and inflammation than those in the around basin group. At the end of the 2-year follow-up, 68 patients had died. Univariate binary logistic regression analysis revealed that a very advanced age, basin group, serum albumin levels, serum creatinine levels, non-anuria, and the complications of stroke and CAD were associated with 2-year mortality.

Multivariate Cox regression analysis revealed that basin group, serum albumin levels, and the complications of stroke and CAD were significant risk factors for 2-year mortality in these patients. The results of this study indicate that factors such as living in the Taipei Basin with higher air pollutant levels in elderly hemodialysis patients is associated with protein-energy wasting and inflammation, as well as 2-year mortality. These findings suggest that among this population, living environment is as important as comorbidities and nutrition. Furthermore, air pollution should be getting more attention especially in the overcrowding Basin topography.

    Rizwan, N.


    Acute renal failure (ARF) is a syndrome characterised by rapid decline in glomerular filtration rate and retention of nitrogenous waste products such as urea and creatinine. The objective of this study was to study the prevalence, risk and outcome of women with obstetrical renal failure. Methods: This observational study was conducted in Department of Obstetrics and Gynaecology, Liaquat University Hospital, Hyderabad, Pakistan from October 2009 to September 2010. Thirty-five patients with obstetrical acute renal failure were included in the study, patients with chronic renal diseases, hypertension, diabetes mellitus and renal stones were excluded from the study. A detailed history was followed by thorough examination and investigation. Their clinical history, physical examination and intake/urine output was recorded. Routine laboratory investigations were done related to each case and specialised investigations like renal scan, renal ultrasonography and renal biopsies were performed in selected cases where recovery was delayed for more than 3 weeks. Results: Total numbers of admissions in obstetric ward were 3,285. Pregnancy related acute renal failure was found in 35 (1.065%) women. Age ranged from 18-40 years. Most of the women belonged to age group 30-35. Out of 35 women 31.42% had postpartum haemorrhage. Ante partum haemorrhage was found in 25.71%, Eclampsia in 17.14%, DIC in 14.28%, and sepsis in 11.42%. Anuria was observed in 25 patients, remaining presented with oliguria (28.57%). Haemodialysis was done in 75% of patients, others were managed conservatively. Complete recovery was observed in 53% cases. Maternal mortality was 25.71% and foetal mortality was 22.85%. Conclusion: Pregnancy related ARF is one of the most common causes of ARF, it is a dangerous complication of pregnancy which carries very high mortality and morbidity. (author)

  2. Black water fever associated with acute renal failure among Congolese children in Kinshasa

    Directory of Open Access Journals (Sweden)

    Joseph M Bodi


    Full Text Available Acute renal failure (ARF is reported in some severe forms of malaria such as black water fever (BWF. It is associated with a high mortality rate and can be managed effectively with adequate renal replacement. A prospective survey of children with dark urine after a malarial infection with Plasmodium falciparum was coupled with a chart review study of patients managed in the past 11 years in the Pediatrics′ Kinshasa University Hospital. Eighty-nine cases of ARF were identified, but data from only 63 patients were available, of whom 44 (69.8% had severe malaria (39 with BWF and 5 with cerebral malaria. The mean age of the patients was 8.2 ± 1.73 years. Of the 39 cases of BWF, an association with quinine ingestion was observed in 32 children (82%. Urea and creatinine levels were elevated in all cases (135.4 ± 88.2 and 3.83 ± 2.81 mg/dL, respectively. Oligo-anuria was observed in 44.4%, severe metabolic acidosis (bicarbonate <15 mEq/L in 61.5% and hyponatremia (<130 mEq/L in 33.3%. Peritoneal dialysis was required in 36 patients, including 20 with BWF. The remaining patients were managed with conservative treatment. Twenty-eight children (44.4%, including 20 on dialysis, fully recovered and 14 died (22.2%, including eight cases of BWF. Our study suggests that ARF is commonly associated with BWF in Congolese children. Elevated urea and creatinine and severe metabolic acidosis were observed more often than other clinical/metabolic disturbances. Severe renal impairment remains a significant complication with a high mortality rate in low-resource settings.

    Laušević Mirjana


    Full Text Available Background/Aim. Besides viral serotype, HLA haplotype and cytokine genes polymorphism are associated with clinical presentation of hemorrhagic fever with renal syndrome. Since these analyses are unavailable in routine clinical practice, the aim of this study was to assess clinical, laboratory and radiographic findings associated with clinical presentation of disease severity. Methods. A total of 30 patients (27 men and 3 women, average age 40 ± 14.9 years, treated for hemorrhagic fever with renal syndrome from January 1, 1999 to December 31, 2009 in Clinical Center of Serbia, were included in the study. Nine patients (30% had mild, 14 (46.7% moderate and 7 (23.3% severe form of the disease; 24 (80% recovered, 6 (20% died in the acute phase of the illness, and 19 patients (63.3% required hemodialysis. Results. The average titer of antiviral antibodies in patients infected with Belgrade serotype virus were significantly higher in those with severe clinical presentation. Hypotension, anuria, macrohaematuria, pulmonary infiltration, pleural effusion, hepatomegalia and positive meningeal signs were more frequent in the patients with severe form of the disease. Statistically significant differences between groups with mild, moderate and severe clinical picture were found in serum total protein, albumin, calcium, glutamate pyruvate and glutamate oxaloacetate transaminase on admittance; serum creatinine and phosphorus concentration on day 14 and day 21; serum sodium and calciums on day 14; hemoglobine concentration on day 21. A statistically significant correlation was found between clinical presentation of the disease severity and platelet count, white blood cell count, hemoglobine concentration, serum calcium and serum transaminases on admittance. Multivariate analysis identified variables` combinations associated with clinical presentation of the disease. Conclusion. Our study confirmed that we can distinguish patients who will manifest different

    The Polypropylene Glycol (PPG) Butyl Ethers function as skinand hair-conditioning agents in cosmetics. Intestinal absorption of the PPG Butyl Ethers was inversely proportional to the molecular weight. In general, the toxicity of the PPG Butyl Ethers decreased as the molecular weight increased. In acute studies, moderate intraperitoneal (IP) doses of various PPG Butyl Ethers caused convulsive seizures in mice and anesthetized dogs, and large oral doses caused decreased activity, anuria, renal tubular swelling and necrosis, and hepatic swelling and necrosis. PPG-2 Butyl Ether vapors were nontoxic by the inhalation route. PPG-2 Butyl Ether was nontoxic in short-term feeding and dermal exposure studies in rats. In animal irritation studies, PPG-2 Butyl Ether caused minor, transient erythema and desquamation; in addition, erythema, edema, ecchymosis, necrosis, and other changes were observed during an acute percutaneous study. PPG-2 Butyl Ether also caused minor to moderate conjunctival irritation and minor corneal injury. PPG-2 Butyl Ether when dermally applied was nontoxic to pregnant rats and was nonteratogenic at doses up to 1.0 ml/kg/day. PPG BE800 at concentrations of 0.001% to 0.26% in feed was noncarcinogenic to rats after 2 years of treatment. In clinical studies, PPG BE800 was nonirritating and nonsensitizing to the skin when tested using 200 subjects. PPG-40 Butyl Ether was neither an irritant nor a sensitizer in a repeat-insult patch test using 112 subjects. Although clinical testing did not indicate significant skin irritation is produced by these ingredients, the animal test data did indicate the potential that these ingredients can be irritating. Therefore, it was concluded that the PPG Butyl Ethers can be used safely in cosmetic products if they are formulated to avoid irritation. Data on the component ingredients, Propylene Glycol, PPG, and n-Butyl Alcohol, from previous cosmetic ingredient safety assessments were also considered and found to support

    Pediatric nephrology is challenging in developing countries and data on the burden of kidney disease in children is difficult to estimate due to absence of renal registries. We aimed to describe the epidemiology and outcomes of children with renal failure in Cameroon. We retrospectively reviewed 103 medical records of children from 0 to 17 years with renal failure admitted in the Pediatric ward of the Douala General Hospital from 2004 to 2013. Renal failure referred to either acute kidney injury (AKI) or Stage 3-5 chronic kidney disease (CKD). AKI was defined and graded using either the modified RIFLE criteria or the Pediatrics RIFLE criteria, while CKD was graded using the KDIGO criteria. Outcomes of interest were need and access to dialysis and in-hospital mortality. For patients with AKI renal recovery was evaluated at 3 months. Median age was 84 months (1QR:15-144) with 62.1% males. Frequent clinical symptoms were asthenia, anorexia, 68.8% of participants had anuria. AKI accounted for 84.5% (n = 87) and CKD for 15.5% (n = 16). Chronic glomerulonephritis (9/16) and urologic malformations (7/16) were the causes of CKD and 81.3% were at stage 5. In the AKI subgroup, 86.2% were in stage F, with acute tubular necrosis (n = 50) and pre-renal AKI (n = 31) being the most frequent mechanisms. Sepsis, severe malaria, hypovolemia and herbal concoction were the main etiologies. Eight of 14 (57%) patients with CKD, and 27 of 40 (67.5%) with AKI who required dialysis, accessed it. In-hospital mortality was 50.7% for AKI and 50% for CKD. Of the 25 patients in the AKI group with available data at 3 months, renal recovery was complete in 22, partial in one and 2 were dialysis dependent. Factors associated to mortality were young age (p = 0.001), presence of a coma (p = 0.021), use of herbal concoction (p = 0.024) and acute pulmonary edema (p = 0.011). Renal failure is severe and carries a high mortality in hospitalized children in Cameroon

    Available data on the characteristics of patients with Ebola virus disease (EVD) and clinical management of EVD in settings outside West Africa, as well as the complications observed in those patients, are limited. We reviewed available clinical, laboratory, and virologic data from all patients with laboratory-confirmed Ebola virus infection who received care in U.S. and European hospitals from August 2014 through December 2015. A total of 27 patients (median age, 36 years [range, 25 to 75]) with EVD received care; 19 patients (70%) were male, 9 of 26 patients (35%) had coexisting conditions, and 22 (81%) were health care personnel. Of the 27 patients, 24 (89%) were medically evacuated from West Africa or were exposed to and infected with Ebola virus in West Africa and had onset of illness and laboratory confirmation of Ebola virus infection in Europe or the United States, and 3 (11%) acquired EVD in the United States or Europe. At the onset of illness, the most common signs and symptoms were fatigue (20 patients [80%]) and fever or feverishness (17 patients [68%]). During the clinical course, the predominant findings included diarrhea, hypoalbuminemia, hyponatremia, hypokalemia, hypocalcemia, and hypomagnesemia; 14 patients (52%) had hypoxemia, and 9 (33%) had oliguria, of whom 5 had anuria. Aminotransferase levels peaked at a median of 9 days after the onset of illness. Nearly all the patients received intravenous fluids and electrolyte supplementation; 9 (33%) received noninvasive or invasive mechanical ventilation; 5 (19%) received continuous renal-replacement therapy; 22 (81%) received empirical antibiotics; and 23 (85%) received investigational therapies (19 [70%] received at least two experimental interventions). Ebola viral RNA levels in blood peaked at a median of 7 days after the onset of illness, and the median time from the onset of symptoms to clearance of viremia was 17.5 days. A total of 5 patients died, including 3 who had respiratory and renal

    ♦ Background, Objectives, and Methods: The number of patients on chronic peritoneal dialysis (CPD) is increasing rapidly on a global scale. We analyzed the International Pediatric Peritoneal Dialysis Network (IPPN) registry, a global database active in 33 countries spanning a wide range in gross national income (GNI), to identify the impact of economic conditions on CPD practices and outcomes in children and adolescents. ♦ Results: We observed close associations of GNI with the fraction of very young patients on dialysis, the presence and number of comorbidities, the prevalence of patients with unexplained causes of end-stage kidney disease, and the rate of culture-negative peritonitis. The prevalence of automated PD increased with GNI, but was 46% even in the lowest GNI stratum. The GNI stratum also affected the use of biocompatible peritoneal dialysis fluids, enteral tube feeding, calcium-free phosphate binders, active vitamin D analogs, and erythropoiesis-stimulating agents (ESAs). Patient mortality was strongly affected by GNI (hazard ratio per $10 000: 3.3; 95% confidence interval: 2.0 to 5.5) independently of young patient age and the number of comorbidities present. Patients from low-income countries tended to die more often from infections unrelated to CPD (5 of 9 vs 15 of 61, p = 0.1). The GNI was also a strong independent predictor of standardized height (p < 0.0001), adding to the impact of congenital renal disease, anuria, age at PD start, and dialysis vintage. Patients from the lower economic strata (GNI < $18 000) had higher serum parathyroid hormone (PTH) and lower serum calcium, and achieved lower hemoglobin concentrations. No impact of GNI was observed with regard to CPD technique survival or peritonitis incidence. ♦ Conclusions: We conclude that CPD is practiced successfully, albeit with major regional variation related to economic differences, in children around the globe. The variations encompass the acceptance of very young patients and

  10. Disease of the kidney and of the urinary tract in De Medicina Methodica (Padua, 1611) of Prospero Alpini (1563-1616). (United States)

    De Santo, Natale Gaspare; Bisaccia, Carmela; Ricciardi, Biagio; Anastasio, Pietro; Aliotta, Giovanni; Ongaro, Giuseppe


    The study was devised to understand the contribution to nephrology ofDe Medicina Methodicaof Prospero Alpini published in 1511, at a time when the fame of the professor reached the azimuth. We have analyzed the contents of chapters devoted to nephrology in that book of Prospero Alpini and the novelties of his message. Prospero Alpini (1563-1616) taught at the University of Padua (1594-1616), at the same time of Galileo Galilei, Santorio Santorio, and Girolamo Fabrizi dAcquapendente, when measurements (pulse, temperature, perspiration) were introduced into medicine. He was a travelling physician to whom we owe fundamental contributions to the use of urine to prognosticate life and death (De Praesagienda vita et morte aegrotantium libri septem, Venetiis, apud Haeredes Melchioris Sessae,1601). As prefect of the Botanical Garden - the first ever and a model in the world - he could turn the study of simples into cures(De Medicina Methodica Libri Tredecim. Patavi, apud Franciscum Bolzettam, 1611. Ex typographia Laurentij Pasquali, is anin foliovolume of XLVII + 424 pages, 54 lines per page), wherein Alpini aimed to rejuvenate antique medical Methodism. It is a testimony of the interest of medicine philosophers of the modern era for the corpuscular and atomic ideas (Nancy Siraisi). Methodists (2ndCentury BC) refused anatomy and physiology as unique guidelines to the interpretations of diseases and gave importance to the development of a pharmacological science and alternative medicine. The book begins with a 3 page letter to Francis Maria della Rovere Duke of Montefeltro, and a 2 page letter to the readers. We discuss the novelties of the chapters on renal colic (de dolorerenum), hematuria (de sanguinis profluvium), pyuria, anuria (de urina suppressa) and its cure, polyuria (de urina profluvio), renal abscesses, hydrops and its treatment by skin incisions. We also analyze the chapter on kidney and bladder stones (Book X, Chapter XVIII, pp. 354-356) - a masterpiece of

    Puljiz, Ivan; Kuzman, Ilija; Turcinov, Drago; Markotić, Alemka; Celjuska, Elvira


    The aim of the study was to examine and analyze the main epidemiologic and clinical data of 94 patients with hemorrhagic fever with renal syndrome (HFRS) hospitalized at the University Hospital for Infectious Diseases in Zagreb during the HFRS outbreak in Croatia in 2002. A total of 110 patients with clinical diagnosis HFRS were treated at the University Hospital for Infectious Diseases in Zagreb. In 110 of HFRS suspected patients, the clinical diagnosis was verified serologically in 94 patients and they were included in the retrospective study. In 93 patients the diagnosis was confirmed by enzyme-linked immunosorbent assay (ELISA), and in one patient by indirect immunofluorescence assay (IFA). Results were analyzed by the use of descriptive statistics. Puumala (PUU) virus infection was verified in 80 (85.1%), Dobrava (DOB) infection in 8 (8.5%) and cross-reactive antibodies to both PUU and DOB viruses in 5 (5.3%) HFRS patients. In one patient who was confirmed by IFA the hantavirus serotype causing HFRS could not be determined. The localities of the presumed HFRS patient exposure to hantaviruses were mostly in the Zagreb area. Most patients were aged 21-50 (83.0%) and male (76.6%). The majority of HFRS cases occurred between May and August (75.5%). A high proportion of HFRS cases were found in the general population from Zagreb and its surroundings (78.7%). The majority of patients were hospitalized in the febrile stage of the disease (70.2%). The main symptoms were: fever (100%), headache (88.3%) and backache (87.2%). Oliguria was recorded in 56.4% and, anuria in 7.5% of patients, however, only three (3.2%) patients required hemodialysis. Six patients developed hemorrhagic manifestations, especially petechiae on the skin and mucosa. One patient in the convalescent stage had subarachnoidal bleeding. Six patients had pathologic electroencephalogram (EEG) findings and two developed epileptic seizures. Lumbar puncture was performed in 12 patients without inflammatory

    histopathologic study. The clinical signs shown by the dogs were lethargy, anorexy, polyuria, oliguria, anuria, polydypsia, vomiting and diarrhea. Urinalysis findings were proteinuria, glucosuria, hematuria, cilindruria, celluria and decrease of urinary specific gravity and crescent values of urinary gamma glutamyl transpeptidase from 24 hours after gentamicin administration until the "end of" the experiment. Azotemia was noticed on the 12th and 14th days of the study. Acute tubular nephrosis was established in the histological evaluation. Based on the results found on this study, the measurement of the urinary gamma glutamyl transpeptidase activity might be considered a sensitive indicator of renal tubular damage allowing early diagnosis of the lesion.

    modificações do metabolismo se traduziram por alterações urinarias e sanguineas. As urinas foram emitidas em muito pequena quantidade (50 cc. em 24 horas não havendo comtudo, anuria absoluta. Cylindros hyalinos e granulosos, bem como leucocytos e cellulas renaes, associadas á albuminoria, era presentes. Os exames chimicos do sangue, revelaram: Proteinas totaes 7,61 grs. em 1000 cc.; Albumina 2,39 grs em 1000 cc.; Globulina 5,22 grs. em 1000 cc.; Uréa 6,42 grs. em 1000 cc.; Fibrinogeneo 0,324 grs. em 1000 cc.; Indican +++; Cl. plasmatico 339 mgrs. em 100 cc.; Cl. globular 170 mgrs. em 100 cc.; Cholesterol 163 mgrs. em 100 cc.; Creatinia 260 mgrs. em 100 cc.; Ph. inorganico 13,4 mgrs. em 100 cc.; Calcio 10,3 mgrs em 100 cc.; Potassio 28 mgrs. em 100 cc.; Sodio 328 mgrs. em 100 cc.. O exame hematologico revelou 11% de hemoglobina; 960.000 hematias por mm.³; e 5.200 leucocytos por mm.³. A formula leucocytaria revelou augmento dos neutrophilos, com 74% dos segmentados. A proporção entre sôro o coagulo foi 9 x 3 cc. A reacção de Wassermann no sôro sanguineo foi negativa. A insufficiencia renal se traduziu no caso em estudo, por modificações humoraes, particularmente pela azotemia elevada, pelo augmento da creatinina, do phosphoro inorganico e do indican. Em contraste com a existencia de taes modificações, o doente não apresentou os signaes clinicos observados nos casos emque a azotemia se mantem elevada, reproduzindo tal facto, o quadro clinico descripto para a necrose symmetrica da cortex renal.In a mortal case of ophidism, in an individual 15 years old, bitten by a snake (Bothrops jararaca on the external face of his right leg and who died 26 days after the accident, the AA. describe the pathologic-anatomical changes met with and the modifications of the metabolism put into evidence through chemical blood examinations. The main changes there existing are located in the kidneys, which present changes of diffused glomerulonephritis and the typic features of

    a history of abdominal pain, pallor, lethargy, and anuria for 36 hours. On physical examination, the patient showed malnutrition, high blood pressure, moderate edema, and hypochondrial pain. Laboratory findings included: urea=112mg/dl, serum creatinine= 4.5 mg/dl, blood pH= 7.47, blood bicarbonate= 12.8 mmol/L, K=7.2 mEq/L. Peritoneal dialysis was started and maintained for 11 days. After 7 weeks, the patient still needed anti-hypertensive drugs and the renal function was still abnormal. Renal biopsy was performed and revealed renal infarction. The result of Doppler ultrasonography revealed absent renal blood flow on the right side. Renal arteriography showed total occlusion of the right renal artery. Results for collagen diseases were negative. A right nephrectomy was performed and the blood pressure was controlled. The child was hospitalized again at 5 years and 8 months old with episodes of absence seizures and abdominal and precordial pain. Anticardiolipin antibody test was positive. The child is now 7 years old, asymptomatic, with negative anticardiolipin antibody, and has been under regular follow-up. COMMENTS: children with arterial thrombosis should be investigated for a possible association with the antiphospholipid antibody syndrome even in the absence of collagen disease.
