Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio were shown to be increased during apnea period and decreased during postapnea hyperventilation period. Our findings may help explain cardiac arrhythmias and sudden death in OSA patients.

Angiofibromas (AFs) are benign, potentially local aggressive, and rich vascular neoplasms that originate from posterior lateral wall of the nasopharynx in adolescent males. However, they could be encountered in sites other than nasopharynx. The maxillary sinus is the most common location of extranasopahryngeal AFs. The nasal septum is an extremely rare location, and only 15 cases had been reported in literature. In this present case, an unusual extranasal AF originating from the anterior part of the nasal septum is reported with its clinical, laboratory, and treatment options and theories proposed to explain the origin of extranasopharyngeal AFs are discussed.

Cutaneous ciliated cyst is defined as a rare, painless lesion frequently encountered on the lower extremities of young girls after puberty. The cyst is surrounded by the columnar ciliary epithelium. Apart from the lower extremities of girls, they may be localized on the scalp, scapula, thumb, abdomen, umbilicus, thigh, heel, knee, and gluteal region. There are two theories to explain this localization. The first is that they are mullerian heterotrophy, while the other is that they are ciliated metaplasia of eccrine glands. In this paper, we described a cutaneous ciliated cyst, which was observed with a previously undescribed localization on the back of a 13-year-old female patient.
