Incidence of tumoral pathology according to study using capsule endoscopy for patients with obscure gastrointestinal bleeding.

Background: Capsule endoscopy has involved a significant advance in techniques for imaging of the small bowel. Its most frequent indication is for studying patients with obscure gastrointestinal bleeding (OGIB). Small bowel tumors are infrequent, representing only 1% to 3% of all malignant gastrointestinal tumors.

[Systemic toxicity caused by local anesthetics after peripheral nerve blocks].

Peripheral nerve blocks have aroused increasing interest in recent years, leading to a rise in the rate of complications. At the same time noteworthy technical advances have been made in areas such as nerve stimulation and ultrasound imaging, and local anesthetics have become safer. Nevertheless, the risk of anesthetic-related systemic toxicity, which manifests with neurological symptoms that tend to be forerunners of cardiovascular ones, can not be ignored.

[New Modern Magpi: meatal advancement and glanuloplasty clinical course].

Introduction: Meatal advancement and glanuloplasty (MAGPI) described by Duckett, has been the most accepted technique for distal hypospadias repair along the last 20 years. Only 50% of the distal variants are amenable to the Magpi; last years several modifications has been reported in order to reach better cosmetic results and to make it available for the most of the distal hypospadias. We report the first 20 cases with some modifications of Magpi.

[Success of endoscopic management in vesicoureteral reflux, conditioned by ureteral dilatation].

Introduction: Endoscopic management has become an important alternative in the treatment of vesicoureteral reflux in children. Since 1995 we indicate it in our Hospital in children with grade II VUR (vesicoureteral reflux) after 1 year of medical management, in all children with grade III VUR and in children with grade IV VUR without reflux nephropathy. According to International Classification of reflux (IRSC), grade IV VUR differ to grade III mainly by the blunting of the calyces and the obliteration of sharp angle of the fornices.

Highlights were sessions under the auspices of two new sections of the Society, the International Xenotransplantation Association and the Section on Transplant Infectious Disease.

Acute renal infarction as a cause of low-back pain.

Detection of acute renal infarction is often delayed or missed because of both the rarity of the disease and its nonspecific clinical presentation. Abrupt onset of low-back pain in a patient at high risk for a thromboembolic event may be the first indication of renal infarction. We report a case of acute renal infarction and review its diagnosis and management.

Kaposiform hemangioendothelioma associated with Milroy's disease (primary hereditary lymphedema).

Kaposiform infantile hemangioendothelioma (KHE) is a rare recently characterized, locally aggressive, endothelial-derived neoplasm that occurs exclusively in the pediatric age group. Milroy-Nonne disease (primary hereditary lymphedema) is an uncommon congenital entity with familiar history of lower limb edema as typical clinical features. An 8-year-old boy developed a hard painless mass in the right leg 7 years after the diagnosis of congenital primary lymphedema of the right lower extremity.

[Management by hypothermia of junctional ectopic tachycardia appearing after pediatric heart surgery].

Junctional ectopic tachycardia (JET) is a complication of the repair of congenital cardiac malformations that responds poorly to conventional treatment. We report our experience with the use of moderate hypothermia in its management. Twelve infants with postoperative JET treated with hypothermia were reviewed.

Villous adenoma of the appendix. Diagnostic and therapeutic approach.

Unlabelled: Appendix villous adenoma is a rare pathological entity that shows a particular form of clinical presentation that is different from villous adenomas in other places along the gastrointestinal tract.

Patients And Methods: We reviewed cases of appendix villous adenoma diagnosed in our hospital during the last five years; we studied age, distribution, sex, clinical presentation, diagnostic methods used, treatment and follow-up of patients.

Results: We diagnosed 6 cases of villous adenoma of the appendix, acute appendicitis being the most common form of clinical presentation.

[Early infection in liver transplant recipients: incidence, severity, risk factors and antibiotic sensitivity of bacterial isolates].

Objectives: To conduct a descriptive study with an analysis of risk factors for early infection in liver transplant patients, and to determine the resistance of the bacteria involved.

Patients And Methods: The study included 149 liver transplant recipients. All cases of infection occurring 0-90 days after transplantation were considered early infection.

Heterotopic brain tissue in the upper lip of a neonate mimicking bilateral cleft lip features.

Heterotopic brain tissue is an extremely rare developmental anomaly frequently diagnosed in the newborn period. This entity has been described in various sites of the head and neck, most commonly in the nasal area. Computed tomography and magnetic resonance imaging are necessary for exclude associated cranial communications.

Aims: To determine the independent factors that predict unplanned hospital readmission in patients who are admitted to a Short-Stay Medical Unit (SSMU). DESIGN AND FIELD OF THE STUDY: Prospective cohort. Sanitary area: 500,000 inhabitants.

Advances in the therapy of von Willebrand disease.

von Willebrand disease (vWD) is a very common autosomal inherited bleeding disorder, caused by a quantitative deficiency or a qualitative structural defect of von Willebrand factor (vWF). Two main therapeutic options are available for the treatment of spontaneous bleeding episodes and for prevention of bleeding: desmopressin (DDAVP) and replacement therapy with plasma products. DDAVP is the treatment of choice for most patients with type 1 vWD.
