ABSTRACT
La enterobiasis es la infección helmíntica más frecuente en nuestro medio. Suele limitarse al tracto gastrointestinal, pero se han descrito casos en otras localizaciones, aunque poco frecuentes. Presentamos el caso de una paciente de 11 años de edad con enterobiasis epiploica, diagnosticada tras ser intervenida mediante laparoscopia por sospecha de apendicitis aguda (AU)
Enterobiasis infestation is the most common helmintic infestation in our environment. It is usually limited to the gastrointestinal tract but other less frequent extra-intestinal locations have been described. We present the case of 11 year old patient with epiploic enterobiasis diagnosed after laparoscopy due to a suspicion of acute appendicitis (AU)

BACKGROUND: Mycophenolate (MF) is effective as induction and maintenance treatment in patients with lupus nephritis (LN). This study evaluates the efficacy and safety of MF in patients with refractory and relapsing LN. METHODS: Data were retrospectively obtained for 85 patients (35 refractory and 50 relapsing) from 11 nephrology departments in Spain. The primary endpoints were the incidence and cumulative number of renal responses and relapses and their relationship with baseline clinical and analytical data. The secondary endpoint was the appearance of side effects. RESULTS: The main clinical and analytical variables were similar both in refractory and relapsing LN. Most of the patients had received cyclophosphamide, and all of them switched to MF. 74 patients (87%) achieved a response (69% partial, 31% complete). Age at starting MF, gender, pathological classification, body mass index, blood pressure, baseline renal function, and proteinuria were not associated with achieving response. After stopping MF, 3 of 19 patients (15.7%) relapsed, all at 6 months of follow-up. No differences were found between clinical and analytical variables and number of relapses. Side effects were unremarkable, except for 1 patient, who died of thrombocytopenia and ovarian hemorrhage. CONCLUSIONS: Switching to MF from other immunosuppressive treatments is effective and safe in refractory and relapsing LN.

BACKGROUND: Mycophenolate (MF) is effective as a maintenance therapy after induction therapy in patients with lupus nephritis (LN). However, little is known about its role in patients with impaired renal function. The purpose of this study was to evaluate the efficacy and safety of MF as a maintenance therapy for LN and its association with renal function. METHODS: Data were obtained for 56 Spanish patients who were receiving MF as a maintenance therapy for LN. Patients were classified into two groups according to renal function at the initiation of MF treatment: group 1 [estimated glomerular filtration rate (eGFR) ≥60 ml/min/1.73 m(2)] and group 2 (eGFR <60 ml/min/1.73 m(2)). The primary endpoints of the study were the rates of renal relapse and responses, and their relationship with baseline renal function. Secondary outcomes were the appearance of side effects during treatment. RESULTS: At initiation of MF treatment, the only differences between the groups were for age, hemoglobin levels, anti-DNA antibody titer, proteinuria, and renal function. In group 1 (n = 38), the eGFR was 98 ± 34 ml/min/1.73 m(2) and in group 2 (n = 18) the eGFR was 43 ± 14 ml/min/1.73 m(2). Only 3 cases had an eGFR <30 ml/min/1.73 m(2). No significant differences were observed in the rate of relapse at 6 months (group 1: 20%; group 2: 23%) or at 12 months (group 1: 25%; group 2: 17%). Response rates were also similar in both groups. Side effects were unremarkable. CONCLUSIONS: MF is effective and safe as a maintenance therapy for LN both in patients with normal renal function and in those with renal impairment.

BACKGROUND: Mycophenolate (MF) is effective as induction therapy for lupus nephritis (LN) in patients with normal renal function; however, little is known about its role in patients with impaired renal failure. The purpose of this study was to evaluate the response to MF in LN and its association with baseline renal function. METHODS: Data were obtained for 90 patients from 12 Spanish renal units who were receiving MF as induction therapy for LN. Patients were classified into 2 groups: group 1 (estimated glomerular filtration rate [eGFR] ≥60 ml/min/1.73 m(2)) and group 2 (eGFR <60 ml/min/ 1.73 m(2)). The primary outcome measure was the percentage of patients who achieved any response and its relationship with initial eGFR. The secondary outcome measures were the percentage of patients who achieved a complete response (CR) or partial response (PR) and the appearance of relapses during treatment and side effects. RESULTS: At initiation of MF treatment, there were no differences in the main parameters between group 1 (n = 63; eGFR 87 ± 23 ml/min/ 1.73 m(2)) and group 2 (n = 27; eGFR 44 ± 12 ml/min/1.73 m(2)). Exposure to prednisone and MF was similar. The percentages of patients who achieved a response in groups 1 and 2 were, respectively, 69.2 and 43.8% at 6 months and 81.3 and 73.7% at 12 months. CR was more frequent in group 1, whereas PR was similar in both groups. Four patients relapsed and side effects were unremarkable. CONCLUSIONS: MF is effective and safe as induction therapy for LN, and response is even achieved in patients with baseline renal impairment.

INTRODUCTION: Outcome of renal transplant from expanded criteria donors (ECD) is usually inferior than those from standard criteria donors (SCD) and may be improved decreasing cold ischemia time (CIT) and minimizing preservation injury. We compare the results obtained with CIT <15 hours in kidney transplants from ECD vs SCD. SUBJECTS AND METHODS: Prospective, single center study of kidney transplants performed since June 2003 to December 2007. Minimum follow-up period was 12 months. Data of donors, receptors and transplant outcome from ECD and SCD are compared. RESULTS: CIT (mean +/- SD) was 9.3+/-2.5 hours in transplants from ECD (n=24) and 8.3+/-3.3 hours in those from SCD (N=50), p=0.18. We did not find significant differences among recipients of grafts from ECD and those from SCD regarding: primary non-function (4.2% vs 2%, respectively), delayed graft function (16.7% vs 10%), surgical complications (25% vs 16%) or acute rejection episodes (8.3% vs 2%). Glomerular filtration rate at one year follow-up was 65.8+/-14.9 ml/min in ECD recipients and 49.4+/-12.5 ml/min (p<0.0001). One year graft survival was 95.8% in ECD recipients and 94% in SCD recipients (p=0.75). CONCLUSIONS: Short CIT in kidney transplant from ECD leads to similar outcome than that obtained from SCD, although renal function is inferior in ECD grafts.

Introducción: Los resultados de los trasplantes efectuados condonantes con criterios expandidos (DCE) son inferiores a los obtenidos con donantes con criterios estándar (DCS). Para optimizar su evolución, se podría reducir su tiempo de isquemiafría (TIF) reduciendo su daño de preservación. Comparamoslos resultados obtenidos al aplicar TIF <15 horas tanto a DCE como a DCS. Material y métodos: Realizamos un estudio unicéntrico, de cohortes, prospectivo, de casos incidentes de trasplante renal de cadáver entre junio de 2003 y diciembre de2007. El tiempo mínimo de seguimiento fue de 12 meses. Comparamos los datos de los donantes, de los receptores y de la evolución de los trasplantes efectuados con DCE frente a los de los DCS. Resultados: El TIF para los DCE (N = 24) y para los DCS (N = 50) fue, respectivamente, de 9,3 ± 2,5 y 8,3± 3,3 horas (p = 0,18). No encontramos diferencias significativas entre los receptores de DCE y DCS en cuanto a: no función primaria del injerto 4,2 vs. 4%, retardo en la función del injerto 16,7 vs. 10%, complicaciones quirúrgicas 25 vs. 16% y rechazos agudos 8,3 vs. 2%. El filtrado glomerular estimado al año para los DCS fue de 65,8 ± 14,9 ml/min y para los DCE de 49,4 ± 12,5 ml/min (p <0,0001). La supervivencia renal al año fue del 95,8% para los receptores de DCE y del 94% para los DCS (p = 0,75). Conclusiones: La aplicación de TIF cortos a los DCE permite conseguir una evolución similar a la de los DCS, aunque su función renal sea en todo momento inferior (AU)

Adrenal myelolipoma is a rare, benign, slow-growing tumor composed of adipose tissue and hematopoietic elements. It is usually diagnosed incidentally, although there are reports of patients with symptoms and descriptions of retroperitoneal hemorrhage due to rupture of large tumors. The condition has been associated with obesity, high blood pressure and adrenal dysfunction. We present a patient with retroperitoneal hemorrhage due to spontaneous rupture of a myelolipoma, hypertension, and renal failure secondary to nephroangiosclerosis.

We present a patient from Germany with Hantavirus infection, admitted in the Emergency room of our hospital, with fever, thrombocytopenia, acute renal failure, oliguria, mild proteinuria and hematuria. Percutaneous renal biopsy revealed an acute interstitial nephritis without medulla haemorrhages. The virus infection confirmation was made by detection of IgM against Hantavirus Puumala. This infection should be considered in patients with thrombocytopenia, fever and acute renal failure, over all if they are from North and Central Europe.

Amyloidosis is a systemic disease characterized by generalized deposition of beta-organized proteic fibrillar material with green birefringence under polarized light, in different tissues and organs, the most frequent kidney, liver and heart, with important clinical repercussion. Primary or AL amyloidosis is the most common subtype of amyloidosis (1), confirmed by biopsy-proved amyloid deposition in abdominal fat pad, rectum, kidney or liver, if necessary, in which fragments of monoclonal light chains are deposited. Cases with factor X (Stuart factor) of coagulation deficiency associated are described, due to adsorption of this factor to amyloid fibrills. Normally, evolution is fatal, with only few months of survival. We report a case of primary amyloidosis with nephrotic syndrome, severe factor X deficiency (without bleeding complications), possible heart affection and short-term good response to chemotherapic treatment.

OBJECTIVES: Presentation of a series of 18 patients who underwent surgery of aldosterone-producing adrenal adenoma (Conn's syndrome) over the last 10 years. Assessment of the most significant clinical and pathological aspects from a surgical point of view. METHODS: Retrospective study evaluating a broad range of features: clinical, analytical, hormonal, imaging, types of anaesthesia, approaches, technique used, intra and post-operative morbidity and mortality, evolution and pathoanatomical diagnosis. RESULTS: The most frequent clinical data of primary hyperaldosteronism were: 94.4% volume-dependent HBP, 50% headaches and dizziness, 27.8% epistasis and/or episodes of angor or acute myocardial infarction, and 22.2% heart failure. The biochemical study and hormonal testing evidenced: hypokalemia in 88.9%, metabolic alkalosis 66.7% and hypernatremia in 61.1%. Mean aldosterone levels were 517.5 pg/mL, and urinary levels 85.9 mcg/day. Resting plasma renin activity (PRA) < 0.2 ng/mL/h in 77.8% cases and positive aldosterone stimulation test in 61.1%: captopril test positive. Imaging diagnosis was based in CAT which was conclusive in 88.9% and ultrasound which was diagnostic in 27.8% cases. The surgical approach was: lumbotomy (over the 11th or 12th rib) in 14 patients and transpleurodiaphragmatic in all remaining patients. The intraoperative complications reported were placement of endothoracic tube due to iatrogenic pneumothorax in two occasions. Duration of the procedure (mean 136.1 min) and post-operative hospitalization (mean 7.76 days), as well as post-surgery follow-up for up to 96 months were also studied. At final time point there was 66.7 asymptomatic patients, 33.3% cases of HBP, and no deaths. CONCLUSIONS: Primary hyperaldosteronism due to adrenal adenoma is an uncommon reason for HBP, but in most cases can be cured with surgery. Biochemical and hormonal testing is determinant to research a diagnosis. Ultrasound and CAT are essential for imaging diagnosis, and occasionally NMR can be of help. Lumbotomy is considered the choice approach for these small tumours as it is a familial technique for urologists with a low complications rate.
