Blood cysts are exceedingly rare benign cardiac tumors, generally involving the cardiac valves. They are found mainly in the first month of life and in children and are very uncommon in adults. We present a rare case of double right atrium blood cysts, incidentally detected by transthoracic echocardiography in an 85-year old patient.

We report a case of aortic valve infective endocarditis (IE) in a 24-year-old man with atopic dermatitis (AD). He had a history of balloon valvuloplasty for a stenotic bicuspid aortic valve, and had dental caries but no invasive dental procedure before the onset of IE. On admission, skin lesions of AD with itching and scratches were found on the neck, trunk, and extremities. Echocardiography showed a vegetation on the aortic valve with mild steno-regurgitation, but extension of IE to the annulus was not detected. Magnetic resonance imaging identified fresh cerebral infarction without neurological dysfunction, leading us to suspect an embolism. Blood cultures grew methicillin-sensitive Staphylococcus aureus. During emergency surgery, a vegetation attached to the conjoined cusp was observed, and the aortic valve was replaced with a mechanical valve. The patient recovered uneventfully without any complications such as recurrent IE or mediastinitis. We also review previously reported cases of IE associated with AD.

We report three cases of left ventricular free wall rupture (LVFWR) after acute myocardial infarction, which were repaired using a sutureless technique without cardiopulmonary bypass. At operation, a sheet of fibrin tissue-adhesive collagen fleece (TachoComb) was secured to the hematoma surrounding the tear and the infarcted area under compression by the surgeon's fingers. After complete hemostasis, several sheets of an absorbable gelatin sponge (Gelfoam) were glued onto the collagen fleece in layers. Intra-aortic balloon pumping was electively performed. Concomitant coronary artery bypass grafting was not carried out. All patients survived the operation but recurrence of the rupture occurred on postoperative day 10 in one patient and an LV aneurysm was found four months after repair in another patient. The sutureless technique may be a simple and fast option for treatment of an oozing type LVFWR; however, careful follow-up is mandatory.

Moxibustion is a technique used in traditional oriental medicine, the aim of which is to cure and/or prevent illness by activating a person's ability for self-healing. In this study, we assessed how moxibustion would affect the immune system and whether it would augment protective immunity. Mice were treated with moxibustion at Zusanli (ST36) acupoints; we analyzed mortality and cytokine activity in sera after infection with herpes simplex virus type 1 (HSV-1), and cytokine gene expression in the skin and the spleen without a virus challenge. Our study demonstrates that pretreatment of BALB/c mice with moxibustion resulted in a marked increase in the survival rate after infection with lethal doses of HSV-1, and elevated serum levels of IL-1β and IFN-γ on days 1 and 6 post-infection with HSV-1. Semi-quantitative RT-PCR assay showed that moxibustion treatment augmented the expression of IL-1α, IL-1β, IL-6, universal-IFN-α, MIP-1α, and TNF-α mRNA in the skin, and IL-1α, IL-1β, IL-12p40, IL-15, u-IFN-α, MIP-1α, and TNF-α mRNA in the spleen. Moreover, moxibustion induces augmentation of natural killer cell activity. Collectively, our study demonstrates that moxibustion activates protective responses against HSV-1 infection through the activation of cytokine production including IFN, and of NK cells.
