[Endocardial Blood Cyst in the Right Atrium:Report of a Case].

A 74-years-old man visited our hospital complaining chest discomfort, and he was diagnosed with variant angina. However, during close examination, a tumor with some small calcified nodules was accidentally pointed out in the right atrium. We carried out surgical removal to prevent embolism.

[Impending Paradoxical Embolization in a Patient with a Thrombus Straddling the Patent Foramen Ovale].

The patent foramen ovale (PFO) is known as a risk of paradoxical embolism in patients with deep venous thromboses. However, PFO is usually found after systemic embolic symptoms become apparent. A 60-year-old male had complained of dyspnea for two weeks.

Vascular compression of the left bronchus in a patient with funnel chest.

We present a case of 5 year-old female with funnel chest, by which cardiovascular structures were displaced into the left chest cavity. This caused left bronchial compression by the pulmonary artery and the descending aorta, for which an external stenting was successfully performed. The patient had features suggestive of skeletal dysplasia with tracheobronchial malacia.

Surgical repair in a patient with Berry syndrome.

Berry syndrome is a trilogy involving an aorto-pulmonary window, right pulmonary artery from ascending aorta and an interrupted aortic arch. Surgical repair for this anomaly is associated with a high mortality rate and incidence of right pulmonary arterial stenosis. Herein, we present the case of a patient with Berry syndrome, who underwent a rapid two-stage repair involving bilateral pulmonary arterial banding and complete repair.

Histochemical changes and apoptosis in degenerating taste buds of the rat circumvallate papilla.

The present study was designed to examine the histochemical changes and occurrence of apoptosis in taste buds of rat circumvallate papillae following bilateral transection of the glossopharyngeal nerve. Following transection of the glossopharyngeal nerve, the number of taste buds was not altered until post-operative day 3 (PO3), but decreased significantly thereafter. The number of cells within a taste bud, however, decreased significantly from PO2.
