Abstract PDF: The clinical manifestations of subacute pacemaker lead-related cardiac perforations are highly variable. Patients with subacute perforations can present with a variety of symptoms, whereas those with acute perforations usually present with cardiac tamponade that necessitates emergent pericardiocentesis. A 32-year-old woman underwent pacemaker implantation for sick sinus syndrome. An active-fixation atrial lead was fixed to the right atrial appendage, and a ventricular lead was fixed to the right ventricle (RV) apex, with acceptable parameters. Two weeks postoperative, the patient visited the clinic for routine examination of the pacemaker parameters. Chest X-ray showed migration of the RV lead beyond the cardiac silhouette. Echocardiography revealed no evidence of pericardial effusion or tamponade. Computed tomography revealed that the RV lead was positioned beyond the RV and pericardium and into the anterior chest wall. Procedural lead revision was performed with cardiothoracic surgery backup. The lead was retracted after loosening the active-fixation screw and inserting the stylet. The lead was placed in the RV septum with active fixation. The procedure was completed without complications, and the patient was discharged after 3 days. Subacute lead perforations can present with various symptoms, and some patients may be asymptomatic without pericardial effusion. Altered lead parameters frequently provide the first indication for the diagnosis of cardiac perforation. Transvenous lead revision with surgical backup is an alternative to surgical extraction.

A rare pathogenic variant identified in a heart transplant recipient with hereditary transthyretin amyloidosis: a case report: Myeong Seop Kim, Soo Youn Lee, Kyung-Hee Kim; Received March 10, 2023 Accepted April 6, 2023 Published online May 30, 2023; DOI: https://doi.org/10.12701/jyms.2023.00241 [Epub ahead of print]

Abstract PDF: Hereditary transthyretin (ATTRv) amyloidosis is a rare and complex genetic disorder that can lead to life-threatening cardiac amyloidosis and rapid disease progression. Early diagnosis and treatment with disease-modifying drugs can improve patient outcomes; however, heart transplantation may be necessary in some patients. We present the unique case of a 65-year-old Korean woman diagnosed with ATTRv amyloidosis after experiencing progressive neurological symptoms, followed by heart failure. Despite the absence of significant symptoms of heart failure, subsequent screening revealed cardiac amyloid infiltration, which caused left ventricular hypertrophy and rapid disease progression. The patient underwent successful heart transplantation, and subsequent genetic testing revealed a pathogenic variant, NM_000371.3:c.425T>C (p.Val142Ala), which affects both the nerves and heart and has not been previously reported in Korea. Our report underscores the potential benefits of heart transplantation in managing advanced ATTRv amyloidosis and emphasizes the need for continued research on the genetic heterogeneity of the disease. Clinicians should consider ATTRv amyloidosis in the differential diagnosis of patients presenting with neurological symptoms and heart failure, particularly in those with a family history of the disease.

Abstract PDF: Musculoskeletal pain is a common reason for patients visiting hospitals or clinics. Various therapeutic tools including oral medications, physical modalities, and procedures have been used to alleviate musculoskeletal pain. Numerous clinical trials have been conducted to demonstrate the therapeutic effect of each treatment and compare the efficacy of different protocols. These trials were conducted under controlled conditions with specific endpoints and timeframes, and the individual constraints of each patient were not considered. We believe that the findings of such studies may not accurately reflect clinical reality in real-world settings. In this article, we propose treatment principles for patients in pain clinics. We propose two principles for pain treatment: first, “Healing, in the end, is not healing.” and second, “The patient’s job is not a patient.” The main role of pain physicians is to quickly and actively reduce pain and help patients focus on their work and lives.

Abstract PDF: Background
Bleeding and thrombosis are major complications associated with high mortality in extracorporeal membrane oxygenation (ECMO) management. Anticoagulant therapy should be adequate to reduce thrombosis. However, related studies are limited.
Methods
We retrospectively reviewed all patients supported with ECMO at a single institution between January 2014 and July 2022 and included those on all types of ECMO using the Permanent Life Support System. Patients were classified into two groups according to their measured mean activated partial thromboplastin time (aPTT) during ECMO management: a high-anticoagulation (AC) group (aPTT, ≥55 seconds; n=52) and a low-AC group (aPTT, <55 seconds; n=79). The primary outcome was thrombotic or bleeding events during ECMO.
Results
We identified 10 patients with bleeding; significantly more of these patients were in the high-AC group (n=8) than in the low-AC group (15.4% vs. 2.5%, p=0.01). However, thrombus events and oxygenator change-free times were not significantly different between the two groups. Four patients in the high-AC group died of bleeding complications (brain hemorrhage, two; hemopericardium, one; and gastrointestinal bleeding, one). One patient in the low-AC group developed a thrombus and died of ECMO dysfunction due to circuit thrombosis.
Conclusion
Heparin did not significantly improve thrombotic outcomes. However, maintaining an aPTT of ≥55 seconds was a significant risk factor for bleeding events, especially those associated with mortality.

Abstract PDF: Thyroid storm is a life-threatening form of thyrotoxicosis and an endocrinological emergency. We present a case of thyroid storm in a patient with metastatic papillary thyroid cancer. A 67-year-old woman with a history of total thyroidectomy 4 years prior to presentation was admitted with deteriorating mental status, fever, and tachycardia. Laboratory tests revealed severe thyrotoxicosis. Although the patient had no residual thyroid tissue after total thyroidectomy, she had a previously diagnosed metastatic thyroid cancer lesion in the pelvic bone. Despite initial treatment with a standard thyroid storm regimen, the patient died 6 days after hospitalization. The patient had no history of Graves disease; however, a thyroxine receptor antibody was detected postmortem. The patient had a history of exposure to an iodine contrast agent, which is a rare cause of thyrotoxicosis. Thyroxine production from a differentiated thyroid carcinoma is rare but can be a source of clinically significant thyrotoxicosis in patients post-thyroidectomy. Overlapping Graves disease is a common stimulus; however, other causes, such as exogenous iodine, cannot be excluded. This case demonstrates that in the setting of metastatic thyroid carcinoma, thyrotoxicosis cannot be completely ruled out as a cause of suspicious symptoms, even in patients with a history of total thyroidectomy.

Abstract PDF: Background
Pregnancy is associated with a number of physical, emotional, and biological changes that can exacerbate maternal psychological disturbances, such as body image concerns and depression. Sleep disturbances during pregnancy can also have adverse impacts. This study aimed to determine the prevalence of depression, sleep disturbances, and body image concerns among pregnant women. The study also examined the relationship between these factors and pregnancy-related variables, such as bad obstetric history and whether the pregnancies were unplanned.
Methods
A cross-sectional study of 146 pregnant patients was conducted at a tertiary care center over 15 months. The patients were administered the Beck Depression Inventory, Pittsburgh Sleep Quality Index, and Body Image Concern Inventory questionnaires. Contingency tables, Fisher exact test, and Spearman correlation were used to identify underlying relationships.
Results
The prevalence of depression was 22.6%. Although body image disturbance was noted in only 2.7% of patients, 46.6% had poor sleep quality. Poor sleep was associated with primigravida status. Bad obstetric history and unplanned pregnancy were associated with depression. Depression was found to be significantly correlated with body image disturbances and poor sleep quality.
Conclusion
Psychiatric disorders were prevalent during pregnancy. This study highlights the importance of screening for depression in pregnant patients. Counselling and caregiver education can be useful for mitigating psychological disturbances. Management of pregnancies by multidisciplinary teams that include psychiatrists could be immensely useful in improving the pregnancy experiences of patients.

Abstract PDF: Biomaterials have been used to supplement and restore function and structure by replacing or restoring parts of damaged tissues and organs. In ancient times, the medical use of biomaterials was limited owing to infection during surgery and poor surgical techniques. However, in modern times, the medical applications of biomaterials are diversifying owing to great developments in material science and medical technology. In this paper, we introduce biomaterials, focusing on calcium phosphate ceramics, including octacalcium phosphate, which has recently attracted attention as a bone graft material.

Abstract PDF: Background
The aim of this study was to analyze the single nucleotide polymorphisms (SNPs) of genes known to be involved in vitamin D metabolism in the placenta using the placental tissue of mothers diagnosed with gestational diabetes mellitus (GDM) to determine whether the SNPs and occurrence of GDM are related.
Methods
We enrolled 80 women of the same gestational age, 40 with and 40 without GDM. The placenta was obtained from each woman after delivery and SNP genotyping was performed on seven SNPs in the CYP27B1 (rs10877012), CYP24A1 (rs2248359, rs6013897, and rs2209314), and GC (rs2282679, rs16847024, and rs3733359) genes. Maternal serum 25-hydroxyvitamin D levels were measured during the first trimester of pregnancy and before delivery.
Results
At the time of delivery, vitamin D levels were lower (21.05±12.05 mg/dL vs. 31.31±20.72 mg/dL, p=0.012) and the frequency of vitamin D deficiency was higher (60.7% vs. 32.5%, p=0.040) in the GDM group. In women with GDM, the G allele of rs10877012 was more common (86.3% vs. 65.0%, p=0.002). The rs10877012 GG genotype was more common in the GDM group (72.5% vs. 42.5%, p=0.007) and the rs10877012 TT genotype was more common in the control group (12.5% vs. 0%, p=0.007).
Conclusion
Mothers with GDM have lower serum concentrations of vitamin D before delivery than healthy controls and vitamin D deficiency is common. A polymorphism in CYP27B1 (rs10877012), is considered to be a cause of GDM pathogenesis.

Evaluation of periodontal status in women with polycystic ovary syndrome versus healthy women: a cross-sectional study: Sandhya Pavankumar, Pavan Kumar Yellarthi, Sandeep JN, Ramanarayana Boyapati, Trinath Kishore Damera, Naveen Vital Kumar G; Received February 4, 2023 Accepted April 4, 2023 Published online May 8, 2023; DOI: https://doi.org/10.12701/jyms.2023.00143 [Epub ahead of print]

Abstract PDF: Background
Polycystic ovary syndrome (PCOS) affects approximately 4% to 12% of females of reproductive age. Previous studies have shown an association between systemic and periodontal diseases. This study aimed to compare the prevalence of periodontal disease in women with PCOS and healthy women.
Methods
A total of 196 women aged 17 to 45 years were included in this study. Oral hygiene index-simplified (OHI-S), gingival index (GI), community periodontal index (CPI), and loss of attachment (LA) were assessed. Individuals who smoked, were pregnant, had any systemic disease (such as type 1 or type 2 diabetes mellitus, cardiovascular disease, malignancy, osteoporosis, and thyroid dysfunction), had a history of systemic antibiotic use in the past three months, or received any periodontal intervention in the past 6 months of screening were excluded. Student t-tests were used to analyze the data. A p-value of <0.05 was considered statistically significant.
Results
Despite similar OHI-S scores (p=0.972) in the two groups, women with PCOS had significantly higher GI, CPI, and LA scores than healthy women (p<0.001).
Conclusion
Periodontal disease was more prevalent in women with PCOS than in healthy women. This finding may be due to the synergistic effects of PCOS and periodontitis on proinflammatory cytokines. PCOS may have an effect on periodontal disease, and vice versa. Hence, education on periodontal health and early detection and intervention for periodontal diseases is of paramount importance in patients with PCOS.

Abstract PDF: Acute phlegmonous esophagitis (APE) is a rare and fatal disease. Phlegmonous infection involves the submucosal layer and muscularis propria but not the mucosal layer. Because surgery is not the first treatment option for this disease, an accurate diagnosis is crucial. Herein, we report three cases of APE with various clinical features. All patients were successfully treated with antibiotics and appropriate medical procedures.

Abstract PDF: Takayasu arteritis (TA) is a disease that causes inflammation and stenosis of medium to large blood vessels. We report a case of a 50-year-old female patient with newly developed hypertension, syncope, and claudication of the extremities. Total occlusion of the left subclavian artery at the origin was found and significant stenosis of the right common iliac artery was revealed by hemodynamic analysis. She was successfully treated with percutaneous angioplasty for multiple peripheral arterial diseases and was finally diagnosed with TA. In consultation with a rheumatologist, medical treatment for TA was initiated, the patient’s hypertension disappeared, and her claudication symptoms improved.

Abstract PDF: Background
Residual monomer tests using high-performance liquid chromatography and cytotoxicity tests were performed to analyze the effect on the oral mucosa of a self-curing resin for provisional crown production.
Methods
A cytotoxicity test was performed to confirm whether leaked residual monomers directly affected oral mucosal cells. The cytotoxicity of the liquid and solid resin polymers was measured using a water-soluble tetrazolium (WST) test and microplate reader.
Results
In the WST assay using a microplate reader, 73.4% of the cells survived at a concentration of 0.2% liquid resin polymer. The cytotoxicity of the liquid resin polymer was low at ≤0.2%. For the solid resins, when 100% of the eluate was used from each specimen, the average cell viability was 91.3% for the solid resin polymer and 100% for the hand-mixed self-curing resin, which is higher than the cell viability standard of 70%. The cytotoxicity of the solid resin polymer was low.
Conclusion
Because the polymerization process of the self-curing resin may have harmful effects on the oral mucosa during the second and third stages, the solid resin should be manufactured indirectly using a dental model.

Abstract PDF: Diffuse large B-cell lymphoma (DLBCL) is a subtype of non-Hodgkin lymphoma (NHL) and is estimated to account for approximately 30% of all NHL cases. NHL can also occur in the female genital tract and accounts for approximately 1.5% of all NHL cases. Many doctors have difficulty diagnosing or treating vulvar DLBCL because of its very low prevalence. A 55-year-old woman presented with a solid mass on the right side of the vulva. No significantly enlarged lymph nodes were observed in the inguinal region. She underwent excisional biopsy at our institution. DLBCL was diagnosed based on histological examination. According to the Hans algorithm, the lesion was diagnosed as a non-germinal center B-cell-like subtype. The patient was referred to a hematologic oncologist. The disease stage was classified as IE according to the Ann Arbor staging classification. The patient received four cycles of chemotherapy with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone and localized radiation therapy with 36 Gy in 20 fractions. She showed complete remission and maintained this status on the latest computed tomography scan. Gynecologists should rule out lymphoma in patients presenting with a vulvar mass.
