Case Report: Acute arterial occlusion of the right lower extremity due to left atrial invasion from pulmonary metastases of thyroid cancer.

Cardiac metastases of thyroid cancer are rare. The most common metastatic route is through lymphatic or hematogenous spread to the right side of the heart. Direct invasion of metastases from other adjacent organs to the left side of the heart is even rarer.

Endovascular repair for arterio-venous fistula treatment: a case report.

Background: Arterio-venous fistula is a rare clinical entity that occurs as a result of a ruptured abdominal aortic aneurysm into the inferior vena cava or iliac vein. Open surgery has been considered the treatment of choice for this condition; however, endovascular repair has become an evolving therapeutic option over the past 20 years. The endovascular treatment has contributed to a decrease in the perioperative mortality; nevertheless, some endovascular repair specific concern for residual fistula still remains.

Anticoagulation Therapy for Pregnancy-Associated Thrombosis: A Retrospective Observational Study.

Pregnancy-associated deep vein thrombosis (DVT) is a rare disease, and data on anticoagulation therapy are lacking. The present study examined the treatment outcome with unfractionated heparin (UFH) subcutaneous injection in patients with pregnancy-associated DVT. This single-center, retrospective, observational study enrolled 15 patients with pregnancy-associated DVT treated from January 2014 to April 2021.

Predicting oxygen requirements in patients with coronavirus disease 2019 using an artificial intelligence-clinician model based on local non-image data.

Background: When facing unprecedented emergencies such as the coronavirus disease 2019 (COVID-19) pandemic, a predictive artificial intelligence (AI) model with real-time customized designs can be helpful for clinical decision-making support in constantly changing environments. We created models and compared the performance of AI in collaboration with a clinician and that of AI alone to predict the need for supplemental oxygen based on local, non-image data of patients with COVID-19.

Materials And Methods: We enrolled 30 patients with COVID-19 who were aged >60 years on admission and not treated with oxygen therapy between December 1, 2020 and January 4, 2021 in this 50-bed, single-center retrospective cohort study.

[Verification of the Prediction of Cedar-pollen Dispersion at the Oita University Faculty of Medicine Complex].

We investigated the accuracy of the prediction of Japanese cedar-pollen dispersion at the Oita University Faculty of Medicine Complex for use in future prediction models. 　We compared the predicted and actual total pollen counts per year, the initial day of pollen scattering, and the daily pollen counts from 2005 to 2014. Total pollen counts per year were predicted by the amount of sunshine in the Hita area, which was considered to be the source of pollen in our previous study, during the previous July.

Efficacy of iliac inflow repair in patients with concomitant iliac and superficial femoral artery occlusive disease.

Background: In multilevel arterial disease, whether complete revascularization or staged runoff repair should be performed remains controversial. The aim of this study was to evaluate the efficacy of iliac inflow repair and to identify clinical conditions that are associated with the need for runoff repair in concomitant iliac and superficial femoral artery (SFA) occlusive disease.

Methods: Patients undergoing inflow repair for complicated flow-limiting iliac lesions with diffuse SFA disease between 2007 and 2013 were retrospectively reviewed.

Total dosage of gardenia fruit used by patients with mesenteric phlebosclerosis.

Background: Mesenteric phlebosclerosis (MP) is a disease characterized by fibrotic change or calcification of the mesenteric vein. Recently, there has been an increase in case reports of MP related to herbal medicine usage. Long-term intake of gardenia fruit (GF) is suspected as a possible cause.

Clinical Search for Undiagnosed Mesenteric Phlebosclerosis at Outpatient Departments Specializing in Herbal (Kampo) Medicine.

Objective: Mesenteric phlebosclerosis (MP) is a disease characterized by calcification of the mesenteric vein, which causes chronic mesenteric ischemia. Recently, the long-term intake of gardenia fruit ('Sanshishi' in Japanese) has been attracting attention as a possible cause. Usually, only advanced, severe MP cases get reported.

Rebamipide improves chronic inflammation in the lesser curvature of the corpus after Helicobacter pylori eradication: a multicenter study.

Background and Aim.

Relation between bile acid reflux into the stomach and the risk of atrophic gastritis and intestinal metaplasia: a multicenter study of 2283 cases.

Background: The relationship between bile acid reflux into the stomach and the risk of atrophic gastritis and intestinal metaplasia is still not well understood. Towards obtaining a better understanding, concentrations of bile acids were measured.

Patients And Methods: This study was carried out with the participation of 14 facilities in Japan, and 2283 samples were collected.

Extracorporeal shock wave therapy improves the walking ability of patients with peripheral artery disease and intermittent claudication.

Background: Despite the recent advances in bypass surgery and catheter interventional therapy for peripheral artery disease (PAD), the long-term outcome of revascularization therapy for infrapopliteal lesions remains unsatisfactory. We have previously demonstrated that low-energy extracorporeal shock wave (SW) therapy effectively induces neovascularization through upregulation of angiogenic factors and improves myocardial ischemia in pigs and humans and in hindlimb ischemia in rabbits. In this study, we thus examined whether our SW therapy also improves the walking ability of patients with PAD and intermittent claudication.

Orbital blowout fracture caused by nose blowing.

The occurrence of an orbital blowout fracture caused by nose blowing is an unusual phenomenon. We report a rare case of such a fracture in the bony floor of the orbit of a 30-year-old man. Immediately after strong nose blowing, he experienced left eyelid edema and diplopia.

[Model analysis of tulobuterol patch formulations to explain the influence of drug release rate and transdermal transfer rate on the plasma concentration profile].

The purpose of this study was to compare the transdermal transfer profiles of brand and generic tulobuterol patch formulations and to evaluate possible changes of in vivo kinetics resulting from increased transdermal transfer by means of pharmacokinetic analysis using reported in vitro drug release rate data and plasma drug concentration profiles. On the assumption that the transdermal transfer rate constant (k2) would be constant (independent of formulation), the drug release rate constant from patch formulation (k1) was predicted to be almost equal to the k2 value (k1≈k2) in the brand formulation, but 2- to 4-fold higher than the k2 value (k1>k2) in the two generic formulations. Under normal conditions, there would be no marked difference in the plasma concentration profiles among the formulations.

Inflammatory popliteal aneurysm.

A 67-year-old man was referred to our department because of fever, right lower thigh swelling, and redness with pain. Laboratory tests showed slightly elevated leukocytes and markedly elevated C-reactive protein levels. Computed tomography confirmed a popliteal aneurysm with wall thickening, so-called mantle sign.
