Unusual sonographic appearance of breast cancer metastasis to the pectoralis muscle.

Breast cancer is one of the most common malignancies in women. It frequently metastasizes to the lungs, liver, and bone. Breast cancer metastasis to skeletal muscles is rare.

Natural History of Invasive Papillary Breast Carcinoma Followed for 10 Years: A Case Report and Literature Review.

Diachronic research on untreated breast cancer completely depends on past medical records when no more recent, advanced methods are available. Herein, we report a case of invasive papillary breast carcinoma followed for 10 years in a 59-year-old woman who refused any treatment. The diagnosis was based on core needle biopsies.

Inverted Meckel diverticulum as a lead point of small bowel intussusception: misinterpreting case as a lipoma.

Inverted Meckel diverticulum is an uncommon cause of intussusception in adults. It may be confused for an intraluminal lipoma. We present a case of small bowel intussusception due to inverted Meckel diverticulum with characteristic computed tomography finding potentially distinguishable from lipoma.

Influence of platelet reactivity on BARC classification in East Asian patients undergoing percutaneous coronary intervention. Results of the ACCEL-BLEED study.

An increasing body of data suggests that East Asian patients have differing risk profiles for both thrombophilia and bleeding compared with Western population. This study was designed to evaluate the relationship of bleeding to platelet function in East Asians undergoing percutaneous coronary intervention (PCI). Patients who had undergone uneventful PCI (n= 301) were prospectively enrolled and bleeding events were evaluated during dual antiplatelet therapy (DAPT) with aspirin and clopidogrel.

Comparison of the ultrastructural and immunophenotypic characteristics of human umbilical cord-derived mesenchymal stromal cells and in situ cells in Wharton's jelly.

The umbilical cord contains mucinous connective tissue, called Wharton's jelly. It consists of stromal cells, collagen fibers, and amorphous ground substances composed of proteoglycan. Recently, these stromal cells have been redefined as a new cell therapy source, named human umbilical cord-derived mesenchymal stromal cells (hUCMSCs).

Sudden infant death syndrome in Korea: a retrospective analysis of autopsy-diagnosed cases.

This study aimed to elucidate the demographic and sleeping environmental factors associated with sudden infant death syndrome (SIDS) in Korea. The autopsy reports of all SIDS cases reported to the National Forensic Service and Seoul National University College of Medicine between 1996 and 2008 were reviewed for data collection and analysis to identify the risk factors for SIDS. Analysis of the 355 SIDS cases reported within the study period revealed that of the 168 (47.

Rupture and spontaneous sealing of a coronary aneurysm after deployment of drug-eluting stent.

Lesions with coronary artery aneurysm (CAA) can become complicated during percutaneous coronary intervention. Here, we report a case of a 78-year-old man who developed a rupture, and spontaneous sealing of the CAA occurred after stent implantation, as shown by computed tomography coronary angiography.

Pharmacodynamic effect of cilostazol plus standard clopidogrel versus double-dose clopidogrel in patients with type 2 diabetes undergoing percutaneous coronary intervention.

Objective: To determine the effect of adding cilostazol (100 mg b.i.d.

Accelerated platelet inhibition by switching from atorvastatin to a non-CYP3A4-metabolized statin in patients with high platelet reactivity (ACCEL-STATIN) study.

Aims: CYP3A4-metabolized statins can influence the pharmacodynamic effect of clopidogrel. We sought to assess the impact of switching to a non-CYP3A4-metabolized statin on platelet function among patients receiving clopidogrel and atorvastatin with high on-treatment platelet reactivity (HPR).

Methods And Results: Percutaneous coronary intervention (PCI)-treated patients (n= 50) with HPR [20 μM adenosine diphosphate (ADP)-induced maximal platelet aggregation (MPA) >50%] were enrolled during chronic administration of atorvastatin (10 mg/day) and clopidogrel (75 mg/day) (≥6 months).

Delayed ventricular septal rupture following blunt chest trauma.

Cardiac injury is a common but occasionally serious complication of blunt chest trauma. A ventricular septal rupture (VSR) is a rare complication and is variable in its presentation, temporal course and severity. Here, we report a rare case of 75-year-old man who developed delayed VSR following blunt chest trauma.

Effect of CYP2C19*2 and *3 loss-of-function alleles on platelet reactivity and adverse clinical events in East Asian acute myocardial infarction survivors treated with clopidogrel and aspirin.

Background: As compared with whites, East Asians more often carry the cytochrome P450 (CYP) 2C19 loss-of-function (LOF) allele with the CYP2C19*3 variant. The influence of the CYP2C19 LOF alleles (*2 and *3) on clopidogrel response and clinical outcomes in East Asians with acute myocardial infarction (AMI) has not been reported. We sought to evaluate the effect of the CYP2C19 variants on clopidogrel pharmacodynamics and long-term prognosis in these patients.

Interaction analysis between genetic polymorphisms and pharmacodynamic effect in patients treated with adjunctive cilostazol to dual antiplatelet therapy: results of the ACCEL-TRIPLE (Accelerated Platelet Inhibition by Triple Antiplatelet Therapy According to Gene Polymorphism) study.

What Is Already Known About This Subject: Compared with standard dual antiplatelet therapy, adjunctive cilostazol to dual antiplatelet therapy ('triple antiplatelet therapy') has a potential to reduce ischemic event occurrence after percutaneous coronary intervention. The pharmacokinetic and pharmacodynamic effects of clopidogrel have been significantly influenced by the enzyme activity of the ABCB1 C3435T and the CYP2C19 system. • For the pharmacokinetics of cilostazol, genetic polymorphisms of the CYP3A5 and CYP2C19 have been associated with the substantial interindividual variability in healthy volunteers.

The concordance and correlation of measurements by multiple electrode and light transmittance aggregometries based on the pre-defined cutoffs of high and low on-treatment platelet reactivity.

The consensus document suggested the definition of high on-treatment platelet reactivity (HPR) and future directions. Although multiple platelet function assays have developed based on different mechanisms, inter-assay concordance of HPR identification may be an important pressing need. This study was performed to correlate between the cutoffs of HPR suggested by multiple electrode (MEA) and light transmittance aggregometries (LTA).

Increased tissue transglutaminase expression in human atherosclerotic coronary arteries.

Background And Objective: Transglutaminase 2 (TGase 2) is a calcium-dependent cross-linking enzyme that catalyzes a covalent iso-peptide bond between two proteins. Interestingly, this catalysis can activate the nuclear factor-kappaB (NF-kappaB) through the polymerization of the inhibitory protein of NF-kappaB (I-kappaB). The objective of the present study was to investigate the expression of TGase 2 in the human atherosclerotic human coronary artery, and the possible roles of TGase 2 in NF-kappaB activation.

Clinicopathologic review of pulmonary silicone embolism with special emphasis on the resultant histologic diversity in the lung--a review of five cases.

It is known that the subcutaneous injection of silicone can lead to severe pulmonary complications, followed in some patients by respiratory failure. Currently, silicone is being increasingly applied in the field of plastic surgery and, unfortunately, the illicit injection of silicone fluid by uncertified practitioners is not uncommon in Korea. We offer a critical pathologic review of 5 cases of pulmonary silicone embolism following illegal injection to the vaginal wall, four of which were fatal and came to legal autopsy.

Decrease in apoptosis and increase in polyploidization of megakaryocytes by stem cell factor during ex vivo expansion of human cord blood CD34+ cells using thrombopoietin.

Thrombopoietin (TPO) is widely used for ex vivo expansion of hematopoietic stem cells. Previously, we have reported that TPO induces a characteristic pattern of apoptosis, and the TPO-induced apoptosis is closely associated with megakaryocyte (MK) differentiation. In the present study, several cytokines, flt3-ligand, stem cell factor (SCF), interleukin-3 (IL-3), IL-6, IL-11, leukemia inhibitory factor, G-CSF, and erythropoietin, which are known to affect megakaryocytopoiesis, have been evaluated to elucidate their effects on the TPO-induced apoptosis.
