Odontogenic cysts have a high prevalence in the dental clinic population, with dentigerous cyst being one of the most frequent ones and whose aetiology involves accumulation of fluid between the reduced enamel epithelium and the crown of an unerupted tooth. In the diagnostic process of these lesions, one should consider complementary imaging exams such as conventional radiography and computed tomography, which are commonly used for providing anatomical information on the tissues compromised by the lesion, but not on the nature of it...

To confirm the nature and forensic significance of questioned skeletal material submitted a medico-legal setting is a relatively common procedure, although not without difficulties when the remains are fragmented or burned. Different methodologies have been described for this purpose, many of them invasive, time and money consuming or dependent on the availability of the analytical instrument. We present a case in which skeletal material with unusual conditions of preservation and curious discovery was sent to a medico-legal setting to determine its human/nonhuman origin...

BACKGROUND: Chemotherapy is one of the most common approaches for cancer treatment. Particularly Doxorubicin has been proven to be effective in the treatment of many soft and solid tumors for locally advanced and metastatic cancer. It is not easy to clinically evaluate the chemotoxic or chemoprotective effect of some drugs, even more when there is a subclinical toxicity. OBJECTIVE: To determine the usefulness of the hepatobiliary, colloid and cardiac scintigraphies, employing 99mTc-disida, 99mTc-phytate and 99mTc-sestamibi respectively, in the evaluation of the hepato and cardiotoxicity of two chemotherapeutic treatments assessed in rats...

Imagenological diagnosis of subarachnoid neurocysticercosis is usually difficult when classical magnetic resonance imaging (MRI) sequences are used. The purpose of this study was to evaluate the advantages of 3D MRI sequences (Fast Imaging Employing Steady-state Acquisition (FIESTA) and Spoiled Gradient Recalled Echo (SPGR)) with respect to classical sequences (Fluid Attenuation Inversion Recovery (FLAIR) and T1) in visualizing Taenia solium cyst in these locations. Forty-seven T. solium cysts located in the basal cisterns of the subarachnoid space were diagnosed in eighteen Mexican patients...

The primary angiitis of the central nervous system (PACNS) is an entity with a very low incidence and prevalence. It is not clear why the inflammatory process of this entity is limited to the cerebral vasculature without systemic manifestations. Its clinical manifestations are very heterogeneous and make clinical diagnosis difficult. In most cases, a brain biopsy is required. Only the clinical suspicion and the ability to recognize the possible clinical and imagenological patterns of presentation make an accurate diagnosis possible...

Cystic hydatid disease (CHD) is a worldwide zoonosis caused by the larval stage of the dog tapeworm Echinococcus granulosus. Diagnosis is based on imagenological tools (abdominal ultrasound, chest X-rays, or computed tomography [CT] scan). Serological antibody-detecting assays, using diverse native antigens, have been used as a supportive diagnostic tool, but their sensitivities and specificities differ greatly. The use of synthetic peptides as antigens should provide more reliability and allow better assessment and comparison of test formats and case series...

Hereditary hemorrhagic telangiectasia (HHT) is a genetic disease with an autosomal dominant inheritance pattern, characterized by widespread telangiectases that can involve the skin, mucous membranes, lung, brain, gastrointestinal tract and/or liver. It has an estimated prevalence of 1 to 2 cases per 10,000. The prevalence of hepatic involvement in HHT had been estimated in 8% to 31% in retrospective studies but in more recent large prospective series the prevalence is higher, ranging between 41% and 78%. Nevertheless, symptoms occur only in 8% of the patients with HHT and liver involvement...

BACKGROUND AND PURPOSE: The right kidney has been less frequently used in live donor nephrectomy, because of the shorter length of the right renal vein (RRV) that is associated with technical difficulties and higher rates of venous thrombosis. In live open donor or deceased donor transplant nephrectomy, an additional cuff of the inferior vena cava is usually removed, but this is a more difficult and risky maneuver in laparoscopic nephrectomy. For this reason, laparoscopic right nephrectomy (LRN) for renal transplantation (RT) is not frequently performed in most medical institutions...

Thyroid dysfunction is more common in women than in men due to the hormone changes which are functional in proper stages such as puberty, pregnancy and menopause. It seems that the interrelationship between the endocrine and immunologic systems may be responsible of the incidence of thyroid dysfunction. The development of precise techniques for the measurement of thyroid hormones as well as the advancement in imagenology studies have contributed to proper diagnosis and therapeutic modalities. Thyroid diseases during pregnancy are now better treated and no harm has been observed in neonates...
