Coronary artery milking is defined as a systolic compression of the coronary artery, usually resulting from myocardial bridging. Rarely, congenital heart disease, pulmonary hypertension and ventricular aneurysm can lead to coronary artery milking, and there has been a reported case of left anterior descending coronary artery milking after coronary stenting. Percutaneous coronary intervention (PCI) is an emerging strategy for treatment of stenosis in the left main stem. We report a case of symtomatic systolic milking at the left main stem treated by direct stenting during PCI in a patient with unstable angina pectoris.

Auranofin has been developed as antirheumatic drugs, which is currently under clinical development for the treatment of chronic lymphocytic leukemia. Previous report showed that auranofin induced apoptosis by enhancement of annexin A5 expression in PC-3 cells. To understand the role of annexin A5 in auranofin-mediated apoptosis, we performed microarray data analysis to study annexin A5-controlled gene expression in annexin A5 knockdown PC-3 cells. Of differentially expressed genes, plasminogen activator inhibitor (PAI)-2 was increased by annexin A5 siRNA confirmed by qRT-PCR and western blot. Treatment with auranofin decreased PAI-2 and increased annexin A5 expression as well as promoting apoptosis. Furthermore, auranofin-induced apoptosis was recovered by annexin A5 siRNA but it was promoted by PAI-2 siRNA. Interestingly, knockdown of annexin A5 rescued PAI-2 expression suppressed by auranofin. Taken together, our study suggests that induction of annexin A5 by auranofin may enhance apoptosis through suppression of PAI-2 expression in PC-3 cells.

Alimentary tract duplications are uncommon congenital anomalies that usually present during the first decade of life. Complete duplication of the colon in adults is very rare and difficult to diagnose preoperatively. We report a case of a 40-year-old female with complete tubular duplication which was initially misdiagnosed as a salpingeal abscess due to colovaginal fistula.

Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) is a rare form of seronegative polyarthritis which is characterized by sudden onset of a symmetrical and peripheral polysynovitis, prominent pitting edema of both hands in elderly patient. It has a benign course and remits completely after steroid treatment. We describe a 77-year-old Korean man of RS3PE syndrome He presented with sudden onset polyarthritis and pitting edema of the dorsum of both hands and both feet. Rheumatoid factor was negative and erythrocyte sedimentation rate was high. Bone scintigraphy showed increased uptake in both wrist, knee, and ankle joints. His synovitis and pitting edema completely disappeared after steroid treatment.

BACKGROUND: We aimed to assess the efficacy of the smartphone-based health application for glucose control and patient satisfaction with the mobile network system used for glucose self-monitoring. METHODS: Thirty-five patients were provided with a smartphone device, and self-measured blood glucose data were automatically transferred to the medical staff through the smartphone application over the course of 12 weeks. The smartphone user group was divided into two subgroups (more satisfied group vs. less satisfied group) based on the results of questionnaire surveys regarding satisfaction, comfort, convenience, and functionality, as well as their willingness to use the smartphone application in the future. The control group was set up via a review of electronic medical records by group matching in terms of age, sex, doctor in charge, and glycated hemoglobin (HbA1c). RESULTS: Both the smartphone group and the control group showed a tendency towards a decrease in the HbA1c level after 3 months (7.7%+/-0.7% to 7.5%+/-0.7%, P=0.077). In the more satisfied group (n=27), the HbA1c level decreased from 7.7%+/-0.8% to 7.3%+/-0.6% (P=0.001), whereas in the less satisfied group (n=8), the HbA1c result increased from 7.7%+/-0.4% to 8.1%+/-0.5% (P=0.062), showing values much worse than that of the no-smartphone control group (from 7.7%+/-0.5% to 7.7%+/-0.7%, P=0.093). CONCLUSION: In addition to medical feedback, device and network-related patient satisfaction play a crucial role in blood glucose management. Therefore, for the smartphone app-based blood glucose monitoring to be effective, it is essential to provide the patient with a well-functioning high quality tool capable of increasing patient satisfaction and willingness to use.

PURPOSE: Pharmacologic provocation test of growth hormone(GH) is a non-physiologic method and has several limitations for diagnosing growth hormone(GH) deficiency. Spontaneous GH release studies could be important in understanding the pathophysiology of children with poor growth but normal responses to GH provocation tests. Also, the relationship between nocturnal GH secretions and sleep patterns in short stature children is poorly understood. The aim of this study is to determine whether there are differences in sleep patterns and nocturnal GH secretory profiles between idiopathic short stature children and a normal stature group. METHODS: Spontaneous nocturnal GH secretions and sleep patterns were evaluated in 12 prepubertal idiopathic short stature children with normal responses to provocation tests and 9 normal stature controls. Blood samples were taken every 30 minutes from 22:00-06:30 and sleep patterns were analyzed by polysomnography. RESULTS: The mean GH level during sleep was significantly lower in short stature children than in controls. The peak GH level after sleep, coincident with the first slow wave sleep, was lower in the short stature group. The slow wave sleep times of short stature children were decreased compared with those of normal subjects. CONCLUSION: These results suggest that overnight serial GH sampling is helpful to identify short stature children with subnormal GH secretions, and sleep structure differences may be associated with decreased overnight GH secretions in short stature children.

Although pancreatitis is known as a common complication during the treatment of acute lymphoblastic leukemia, acute pancreatitis that's induced by 6-mercaptopurine or 6-thioguanine is very uncommon. We experienced the case of an 11-year-old boy with consecutive acute pancreatitis, and this was induced by 6-mercaptopurine and 6-thioguanine during maintenance chemotherapy of childhood acute lymphoblastic leukemia. We report here on this along with a review of the pertinent literature.

Background:
Rapid revascularization is the key to better patient outcomes in ST-elevation myocardial infarction (STEMI). Direct activation of cardiac catheterization laboratory (CCL) using artificial intelligence (AI) interpretation of initial electrocardiography (ECG) might help reduce door-to-balloon (D2B) time. To prove that this approach is feasible and beneficial, we assessed the non-inferiority of such a process over conventional evaluation and estimated its clinical benefits, including a reduction in D2B time, medical cost, and 1-year mortality.
Methods:
This is a single-center retrospective study of emergency department (ED) patients suspected of having STEMI from January 2021 to June 2021. Quantitative ECG (QCG™), a comprehensive cardiovascular evaluation system, was used for screening. The non-inferiority of the AI-driven CCL activation over joint clinical evaluation by emergency physicians and cardiologists was tested using a 5% non-inferiority margin.
Results:
Eighty patients (STEMI, 54 patients [67.5%]) were analyzed. The area under the curve of QCG score was 0.947. Binned at 50 (binary QCG), the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were 98.1% (95% confidence interval [CI], 94.6%, 100.0%), 76.9% (95% CI, 60.7%, 93.1%), 89.8% (95% CI, 82.1%, 97.5%) and 95.2% (95% CI, 86.1%, 100.0%), respectively. The difference in sensitivity and specificity between binary QCG and the joint clinical decision was 3.7% (95% CI, −3.5%, 10.9%) and 19.2% (95% CI, −4.7%, 43.1%), respectively, confirming the non-inferiority. The estimated median reduction in D2B time, evaluation cost, and the relative risk of 1-year mortality were 11.0 minutes (interquartile range [IQR], 7.3–20.0 minutes), 26,902.2 KRW (22.78 USD) per STEMI patient, and 12.39% (IQR, 7.51–22.54%), respectively.
Conclusion
AI-assisted CCL activation using initial ECG is feasible. If such a policy is implemented, it would be reasonable to expect some reduction in D2B time, medical cost, and 1-year mortality.

Human leukocyte antigen (HLA) is a group of glycoproteins encoded by the major his-tocompatibility complex (MHC) that plays a pivotal role in the host's immune defense.Given that the MHC represents the most polymorphic region in the human genome, HLA typing is crucial in organ transplantation. It significantly influences graft rejection, graft-versus-host disease, and the overall patient outcome by mediating the discrimination between self and nonself. HLA typing technology began with serological methods and has evolved rapidly alongside advances in molecular technologies, progressing from DNA-based typing to next- or third-generation sequencing. These advancements have increased the accuracy of HLA typing and reduced ambiguities, leading to marked improvements in transplantation outcomes. Additionally, numerous novel HLA alleles have been identified. In this review, we explore the developmental history and future prospects of HLA typing technology, which promises to further benefit the field of transplantation.
