Comparison of both lower leg bone mineral density in single limb knee osteoarthritis patients.

Purpose: The relationship between knee osteoarthritis (OA), bone mineral density (BMD), and alignment has not yet been clarified. This study aimed to investigate the relationship between the two limbs in patients with single-limb knee OA.

Methods: Patients who underwent single-limb total knee arthroplasty between March 2019 and February 2021 were retrospectively analyzed.

Predictive values of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and other prognostic factors in pediatric vestibular neuritis patients.

Objective: To analyze the relationship between severity and hemodynamic factor in pediatric vestibular neuritis patients and find out their effectiveness as a prognostic factor.

Study Design: Retrospective review.

Setting: Tertiary medical center.

Rhino-Orbito-Cerebral Mucormycosis in an Immunocompromised Patient.

Rhino-orbito-cerebral mucormycosis (ROCM) is an invasive fungal infection that usually occurs in immunocompromised patients. It is aggressive and has a high risk of mortality. With unclear guidelines, ROCM is treated in various ways.

Bilateral Orbital Apex Syndrome Related to Sphenoid Fungal Sinusitis.

Orbital apex syndrome (OAS) is a rare condition that usually occurs due to damage to surrounding inner and surrounding bone tissue. Orbital apex syndrome may result from a variety of conditions that cause damage to the superior orbital fissure and to the optic canal leading to optic nerve (II) dysfunction. We recently experienced a rare case of sphenoidal , which damaged the adjacent cavernous sinus structures and led to the definite symptom of bilateral OAS in a 77-year-old male.

The Effect of Korean Red Ginseng on Symptoms and Inflammation in Patients With Allergic Rhinitis.

Korean red ginseng (KRG) has been traditionally used in Korea for health improvement. However, the clinical effect of KRG intake on the symptoms in patients with allergic rhinitis remains unknown. Our study was performed to identify the clinical effects of KRG on patients with allergic rhinitis and to examine the effect of KRG on allergic inflammatory reaction.

Nrf2-Heme Oxygenase-1 Attenuates High-Glucose-Induced Epithelial-to-Mesenchymal Transition of Renal Tubule Cells by Inhibiting ROS-Mediated PI3K/Akt/GSK-3 Signaling.

Background: Epithelial-to-mesenchymal transition (EMT) is thought to play a significant role in the advancement to chronic kidney disease and contributes to the deposition of extracellular matrix proteins and renal fibrosis relating to diabetic nephropathy.

Method: We studied the effect of Nrf2-HO-1 signaling on high-glucose- (HG-) induced EMT in normal human tubular epithelial cells, that is, HK2 cells. In short, we treated HK2 cells with HG and sulforaphane (SFN) as an Nrf2 activator.

Nrf2-Heme oxygenase-1 modulates autophagy and inhibits apoptosis triggered by elevated glucose levels in renal tubule cells.

Background: Autophagy is a highly balanced process in which lysosomes remove aged and damaged organelles and cellular proteins. Autophagy is essential to maintain homeostasis in the kidneys.

Methods: Using human renal tubule cells HK-2, we assessed the impact of high glucose (HG) on autophagy.

Fibrillary glomerulonephritis combined with chronic inflammatory demyelinating polyneuropathy.

A 58-yr-old man presented with leg edema and subacute weakness of his bilateral lower extremities. Urinary and serum immunoelectrophoresis revealed the presence of lambda-type Bence Jones proteins. He was ultimately diagnosed with monoclonal gammopathy of undetermined significance (MGUS).

Effect of topical vitamin D on chronic kidney disease-associated pruritus: An open-label pilot study.

Chronic kidney disease-associated pruritus (CKD-aP) is a troublesome symptom in patients with end-stage renal disease (ESRD). Recently, vitamin D deficiency has been known to be one of the possible etiologic factors in CKD-aP. However, limited data is available on whether topical vitamin D treatment is effective for relieving CKD-aP.

Porcelain heart: rapid progression of cardiac calcification in a patient with hemodialysis.

Cardiac calcification usually occurs in patients with end-stage renal disease. However, rapid progression of cardiac calcification is rarely associated with secondary hyperparathyroidism of end-stage renal disease. We report a patient with end-stage renal disease who showed moderate left ventricular hypertrophy at the first echocardiography, and showed severe myocardial calcification and severe mitral valve stenosis 4 years later.

Activation of AMP-activated protein kinase inhibits albumin-induced endoplasmic reticulum stress and apoptosis through inhibition of reactive oxygen species.

Background: Endoplasmic reticulum (ER) stress induced by urinary albumin plays an important role in tubulointerstitial injury. We have shown that albumin-induced ER stress is regulated through reactive oxygen species (ROS)-c-Src kinase-mTOR signaling pathways. We postulated that peroxisome proliferator-activated receptor-γ (PPAR-γ) might also act as an upstream signaling molecule between c-Src kinase and mTOR.

Activation of spleen tyrosine kinase is required for TNF-α-induced endothelin-1 upregulation in human aortic endothelial cells.

Endothelin-1 (ET-1) promotes atherosclerosis. We tested whether spleen tyrosine kinase (Syk) mediates tumor necrosis factor-α (TNF-α)-induced ET-1 upregulation in human aortic endothelial cells (HAECs) and sought to identify the signal pathways involved. TNF-α-induced reactive oxygen species (ROS) activated Syk and phosphatidylinositol 3-kinase (PI3K), which was required for the activation of AP-1 and subsequent ET-1 gene transcription.

Desmopressin improves platelet dysfunction measured by in vitro closure time in uremic patients.

Background/aims: Desmopressin decreases bleeding time in uremic patients. Although bleeding time is the most frequently used measure of global platelet function, this test has important disadvantages. In vitro closure time (CT) is a relatively new and efficient test of primary hemostasis.
