A suitable device for cystic lesions close to the tooth-bearing areas of the jaws.

Different devices for decompression of cystic lesions of the jaw have been described in the literature. Although there are no rigorous rules for choosing a particular design or method, the choice depends on situational needs. Although minor, most techniques are associated with certain difficulties and complications, such as the need for long-term monitoring, inappropriate decompression tube size, soft tissue trauma, suture dehiscence, soft tissue invagination, dislodgement, and malpositioning of the tube into the lesion.

Sentinel lymph node biopsy in patients with locally advanced breast cancer after neoadjuvant chemotherapy.

Purpose: To check the rate of sentinel lymph node (SLN) identification in patients with locally advanced breast cancer who underwent neoadjuvant chemotherapy comparing intraoperative contact cytology (imprint) and embedded in paraffin and validation of methods.

Methods: A cross-sectional validation of diagnostic test involving 34 patients from the outpatient clinic of the Maternity School Assis Chateaubriand. The patients had locally advanced breast cancer and were treated with neoadjuvant chemotherapy.

The use of Le Fort I Approach in the resection of an extensive ossifying fibroma.

Introduction: Ossifying fibroma (OF) is a well-defined benign neoplasm characterized by slow growth and predilection for the posterior mandible site, usually treated by conservative surgical approaches. In this context, Le Fort I Approach (LFIA) has been increasingly used providing good visualization and an easy access to the lesion. It also allows removal of the lesion quickly.

is a systemic auto-immune medical condition that mainly manifests with changes in skin and vasculopathy. This is a case report of a 69-year-old male with confirmed histopathologic diagnosis of presenting ulterior Cognitive Impairment, mostly in executive function. The patient was treated using steroids, immunomodulatory therapy, fluoxetine and galantamine.

Metabolic and oxidative effects of sevoflurane and propofol in children undergoing surgery for congenital heart disease.

Purpose: To evaluate the metabolic and oxidative effects of sevoflurane and propofol in children undergoing surgery for correction of congenital heart disease.

Methods: Twenty children with acyanotic congenital heart disease, scheduled for elective cardiac surgery with cardiopulmonary bypass, age range 1 day to 14 years were randomly assigned to 2 groups: Group GP, programmed to receive total intravenous anesthesia with propofol and group GS scheduled to use balanced anesthesia with sevoflurane. Exclusion criteria were cyanotic heart disease or complex, association with other malformations, severe systemic diseases, infection or children undergoing treatment and palliative or emergency surgery.

Renal dysfunction in leprosy: a historical cohort of 923 patients in Brazil.

We investigated the factors associated with renal dysfunction in leprosy patients from Brazil. We report on a historical cohort of leprosy patients followed in two hospitals in Fortaleza City in northeastern Brazil. The factors associated with renal dysfunction were investigated.

Rare hybrid odontogenic tumor in a 2-year-old child.

Hybrid odontogenic tumors are rare conditions that can affect the oral maxillofacial region and usually occur in adults as an asymptomatic swelling. Hybrid odontogenic tumors exclusively involving adenomatoid odontogenic tumor (AOT) and calcifying cystic odontogenic tumor (CCOT) are rare, with only 4 reported cases. In addition, there are only few studies describing the presence of abortive enamel in AOT and, to our knowledge, CCOT was not present in any of them.

Acute kidney injury after trauma: Prevalence, clinical characteristics and RIFLE classification.

Background: Acute kidney injury (AKI) is an uncommon but serious complication after trauma. The objective of this study was to evaluate the prevalence, clinical characteristics and outcome of AKI after trauma.

Patients And Methods: This was a retrospective study performed from January 2006 to January 2008 in an emergency specialized hospital in Fortaleza city, northeast of Brazil.

Antimicrobial resistance of uropathogens in women with acute uncomplicated cystitis from primary care settings.

We assessed the antimicrobial resistance patterns of all urine samples submitted for culture from outpatient women aged ≥14 years with diagnosis of uncomplicated cystitis over a 24-month period (2007-2009) in the city of Fortaleza, Brazil. Only bacterial growth of a single uropathogen with ≥10(5) CFU/mL was considered for analysis. The Pearson's chi-square test was used for bivariate correlations.

Paraneoplastic syndromes and the kidney.

A paraneoplastic syndrome is defined as a group of symptoms that develop when substances released by some cancer cells disrupt the normal function of the surrounding cells and tissue. Paraneoplastic renal syndromes are diseases that indirectly compromise tubular and glomerular function by electrolyte imbalance, hormone-producing tumors or deposition of antigen-antibody complexes in the glomeruli. In order to describe the most common paraneoplastic syndromes, which may compromise the renal function, an extensive review was performed of papers, including case reports, guidelines, meta-analysis and other scientific publications.
