RESUMO
Gouty panniculitis is caused by the deposition of urate crystals in the subcutaneous tissue, accompanied by a lobular panniculitis. It presents as subcutaneous nodules, most commonly located on the lower extremities. Being an unusual clinical presentation of gout, the sonographic findings of gouty panniculitis have been scarcely described in the literature. Our report describes the ultrasound features we found in a case of gouty panniculitis and the usefulness of this technique for diagnosis and monitoring of this disease.

La infección por Helicobacter pylori es una de las causas más frecuentes de infección bacteriana crónica en el ser humano. A través de distintos factores patogénicos (adhesinas, ureasa, proteínas citotóxicas cagA y vacA) puede producir cambios que se pueden apreciar en una endoscopia digestiva alta. Estos incluyen la aparición de lesiones ulcerosas, mucosa en empedrado y palidez alternando con eritema, entre otros. Sus dianas preferentes en la edad pediátrica son el antro gástrico y el duodeno proximal. Este artículo hace una revisión de los hallazgos endoscópicos relacionados con la infección por H. pylori en niños, así como de sus posibles causas y consecuencias clínicas (AU)
H. pylori infection is one of the most frequent chronic bacterial infections in human beings. Through different pathogenic factors (adhesins, urease, cagA and vacA cytotoxic proteins) it may produce mucosal changes that can be seen in an upper gastrointestinal endoscopy. These changes include, among others, ulcerative lesions, cobblestone mucosa and pallor alternating with erythema. Its favorite targets in children are the gastric antrum and proximal duodenum. This article reviews the endoscopic findings related to H. pylori infection in children and their possible causes and clinical consequences (AU)

Renal cell carcinoma have a great capacity of dissemination and have a great variety of clinical presentation. We exposed a clinical note of a patient diagnosed of renal cell carcinoma who developed hematuria and acute urinary retention due to a penis metastasis. Next we review the literature about this topic.

El carcinoma renal de células claras es una neoplasia con gran capacidad de diseminación y que se presenta de formas muy variadas. Presentamos un caso clínico de un sujeto que desarrolla hematuria y retención aguda de orina secundarias ambas a metástasis en pene de un carcinoma renal de células claras. A continuación se lleva a cabo una pequeña revisión de la literatura existente sobre metástasis en esta localización (AU)

STUDY DESIGN: The case of a 16-year-old patient with an osteochondroma in T11 and scoliosis is reported. OBJECTIVE: To describe the treatment of an osteochondroma with scoliotic deformity and the imaging methods used for the diagnosis. SUMMARY OF BACKGROUND DATA: Osteochondromas arising in the vertebral column are rare. However, spinal involvement is found with some regularity because osteochondromas are among the most common benign tumors of bone. METHODS: The clinical history, plain radiographs, computed tomography, and magnetic resonance imaging, and pathologic findings of the reported patient were reviewed. The medical literature also was reviewed. RESULTS: The patient was treated with surgery in an attempt to remove the tumor and correct the aesthetic deformity. The results were satisfactory, with an improvement of the thoracolumbar scoliosis from 45 degrees to 18 degrees. CONCLUSIONS: Osteochondromas of the vertebral column may cause scoliosis. Computed tomography and magnetic resonance imaging are necessary for evaluating the origin, size, and characteristics of the tumor. In this case, surgical management involved resection of the tumor and correction of the scoliotic deformity.
