RESUMEN
Spindle cell tumors exhibit a relatively low occurrence rate and can manifest in various locations within the human body, including soft tissues and bones. The process of making a diagnosis is supported by conducting pathological and immunohistochemical tests. A 50-year-old female patient visited the hospital with abdominal pain that lasted about a week. Magnetic resonance imaging of the pelvis showed that this mass was independent and was not a lymph node mass, but a retroperitoneal sarcoma type mass. As part of the treatment, the mass was surgically excised, and a supracervical hysterectomy was carried out. The tumor was wrapped in a grayish-white capsule and showed a lobulating pattern. Retroperitoneal spindle cell tumors, particularly those occurring in abdominal soft tissues, are infrequently observed. Histopathological diagnosis is done in stages, and when cases are ambiguous, immunohistochemistry can provide valuable guidance in the right direction.
RESUMEN
A caracterização atual dos distúrbios respiratórios do sono compreende desde a síndrome de apnéia do sono até a síndrome de resistência das vias aéreas superiores. A fisiopatologia dos distúrbios respiratórios do sono na infância mantém complexas correlações com a respiração bucal. Com freqüência, crianças com distúrbios respiratórios do sono podem desenvolver alterações comportamentais, tais como déficit de atenção e hiperatividade, bem como manifestar sonolência ou, ainda, apresentar complicações sistêmicas cardiovasculares e déficit pôndero-estatural. Com base na literatura recente sobre o tema, são apresentadas as correlações entre os distúrbios respiratórios do sono e o transtorno do déficit de atenção/hiperatividade.
The recent concept of sleep disordered-breathing ranges from the sleep apnea syndrome to the upper airways resistance syndrome. The physiopathology of sleep-disordered breathing includes complex relations with oral breathing. Children with sleep-disordered breathing often present behavioral disorders, such as attention deficit and hyperactivity, excessive daytime sleepiness as well as systemic cardiovascular or growth. Based on recent references, we discuss the correlations between sleep-disordered breathing and attention deficit/hyperactivity disorder.
