Successful Surgical Repair of Type A Acute Aortic Dissection in a Patient with Vascular Ehlers-Danlos Syndrome.

Surgery for vascular complications of a patient with vascular Ehlers-Danlos syndrome (vEDS) is challenging due to the fragility of the associated tissues. In this study, we present a type A acute aortic dissection case in a patient with vEDS successfully treated via total arch replacement. A 42-year-old woman was transferred to our hospital 10 days after the onset of symptoms and underwent emergency surgery.

An anomalous hyperplastic anterior choroidal artery associated with an unruptured internal carotid-posterior communicating artery aneurysm.

The anterior choroidal artery (AChA) injuries can result in severe neurologic deficits, so requiring careful observation to avoid inadvertent damage during neuroendovascular procedures. In this case report, we present the unusual case of an anomalous hyperplastic AChA associated with a fetal-type posterior communicating artery (PCoA), and an unruptured internal carotid artery (ICA) -PCoA aneurysm. A 54-year-old woman presented with persistent headache.

Influence of preoperative right ventricular function on left ventricular remodeling and survival after subvalvular repair for functional mitral regurgitation.

Objectives: The objective of this study was to analyze our surgical experiences with mitral valve plasty (MVP) combined with subvalvular procedures (SVPs) for functional mitral regurgitation (FMR) and to determine which preoperative factors affected clinical outcomes.

Methods: This study retrospectively analyzed 33 patients who underwent MVP combined with SVPs for FMR with a left ventricular ejection fraction lower than 40% and advanced remodeled left ventricles. The mean follow-up period was 49 ± 33 months.

Successful treatment of left ventricular patch infection by latissimus dorsi muscle flap covering without patch removal.

Removal of the infected prosthesis is considered an essential procedure in the treatment of prosthetic graft infection following cardiovascular surgery. Here, we present a case of left ventricular patch infection following repair of left ventricular rupture that was successfully treated by coverage with a latissimus dorsi muscle flap without patch removal. A 61-year-old man underwent double-patch repair for left ventricular-free wall rupture following posterior myocardial infarction.

Clinical Outcomes of a Customized Mitral Valve Plasty for Functional Mitral Regurgitation with a Low Ejection Fraction and Implications for Preoperative Right Ventricular Function.

Purpose: To evaluate clinical outcomes of customized mitral valve plasty (MVP) for the treatment of functional mitral regurgitation (FMR) with a low ejection fraction (EF) and to determine which preoperative factors affected the clinical outcome.

Methods And Results: MVP was adjusted according to the degree of left ventricle (LV) remodeling. We performed mitral annuloplasty (MAP) alone in 14 patients and added subvalvular procedures (SVPs) in 22 patients at a high risk of recurrent MR.

Investigation of aluminum and iron deposition on metaplastic bones in three patients with diffuse pulmonary ossification.

Diffuse pulmonary ossification (DPO) is a rare pulmonary lesion. DPO is typically detected at autopsy rather than premortem. Recently, however, several cases were diagnosed antemortem using computed tomography, high-resolution computed tomography, or video-assisted thoracic surgery.

[Bilateral sensorineural hearing impairment due to Streptococcus suis meningitis 20 days after swine bite].

Streptococcus suis (S. suis) is a zoonotic pathogen in pigs, which can be transmitted to humans by close contact. Meningitis is the most common clinical manifestations of S.

Growth temperatures of archaeal communities can be estimated from the guanine-plus-cytosine contents of 16S rRNA gene fragments.

Prokaryote growth temperatures in environmental samples are difficult to measure because it is hard to culture viable prokaryotes in natural environments. We comprehensively surveyed growth temperatures and 16S rRNA sequences of prokaryotes to estimate their growth temperatures based on guanine-plus-cytosine contents (P(GC)) of their 16S rRNA sequences. We focused on archaea because of the wide range of growth temperatures within this group.

In situ biomass production of a hot spring sulfur-turf microbial mat.

Sulfur-turf microbial mats develop in sulfide-containing hot spring water dominated by chemolithoautotrophic sulfur-oxidizing bacteria. The sulfur-turf mat that developed at a source of hot water (72°C, pH 6.8) exhibited a growth rate of 0.

Biomass production and energy source of thermophiles in a Japanese alkaline geothermal pool.

Microbial biomass production has been measured to investigate the contribution of planktonic bacteria to fluxations in dissolved organic matter in marine and freshwater environments, but little is known about biomass production of thermophiles inhabiting geothermal and hydrothermal regions. The biomass production of thermophiles inhabiting an 85 degrees C geothermal pool was measured by in situ cultivation using diffusion chambers. The thermophiles' growth rates ranged from 0.

[A case of pulmonary carcinomatous lymphangiosis exhibiting multiple patchy opacities, caused by CA 19-9 producing metastatic stomach cancer].

A 64-year-old man was admitted to our hospital complaining of Hugh-Jones II dyspnea. Chest CT showed multiple diffuse patchy shadows in both lung fields. A diagnosis of pulmonary carcinomatous lymphangiosis was made on the basis of the presence of adenocarcinoma cells within the lymphatic vessels in transbronchial lung biopsy (TBLB) specimens.
