The bicuspid aortic valve (BAV) is the most common congenital cardiovascular malformation. Patients with BAV are at higher risk of other congenital cardiovascular malformations and valvular dysfunction, including aortic stenosis/regurgitation and infective endocarditis. BAV may also be related to aortic wall abnormalities such as aortic dilatation, aneurysm, and dissection. The morphology of the BAV varies with the presence and position of the raphe and is associated with the type of valvular dysfunction and aortopathy. Therefore, accurate diagnosis and effective treatment at an early stage are essential to prevent complications in patients with BAV. This pictorial essay highlights the characteristics of BAV and its related congenital cardiovascular malformations, valvular dysfunction, aortopathy, and other rare cardiac complications using multimodal imaging.

BACKGROUND/OBJECTIVES: In this study, potential anti-inflammatory effect of enzymatic hydrolysates from Styela clava flesh tissue was assessed via nitric oxide (NO) production in lipopolysaccahride (LPS) induced RAW 264.7 macrophages and in vivo zebrafish model. MATERIALS/METHODS: We investigated the ability of enzymatic hydrolysates from Styela clava flesh tissue to inhibit LPS-induced expression of pro-inflammatory mediators in RAW 264.7 macrophages, and the molecular mechanism through which this inhibition occurred. In addition, we evaluated anti-inflammatory effect of enzymatic hydrolysates against a LPS-exposed in in vivo zebrafish model. RESULTS: Among the enzymatic hydrolysates, Protamex-proteolytic hydrolysate exhibited the highest NO inhibitory effect and was fractionated into three ranges of molecular weight by using ultrafiltration (UF) membranes (MWCO 5 kDa and 10 kDa). The above 10 kDa fraction down-regulated LPS-induced expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), thereby reducing production of NO and prostaglandin E2 (PGE2) in LPS-activated RAW 264.7 macrophages. The above 10 kDa fraction suppressed LPS-induced production of pro-inflammatory cytokines, including interleukin (IL)-1beta, IL-6, and tumor necrosis factor (TNF)-alpha. In addition, the above 10 kDa fraction inhibited LPS-induced phosphorylation of extracellular signal-regulated kinases (ERKs), c-Jun N-terminal kinase (JNK), and p38. Furthermore, NO production in live zebrafish induced by LPS was reduced by addition of the above 10 kDa fraction from S. clava enzymatic hydrolysate. CONCLUSION: The results of this study suggested that hydrolysates derived from S. clava flesh tissue would be new anti-inflammation materials in functional resources.

Congenital melanocytic nevus is a hamartoma derived from the neural crest that is present at birth. Regression following surgical excision with an apparent halo phenomenon through suture lines has never been reported. A nine-year-old boy presented with a solitary symmetric, oval-shaped, blackish pigmented patch on his right forearm.He reported increasing size of the lesion with no other subjective symptoms. Histological examination of the first excisional biopsy revealed congenital melanocytic nevus, and serial excisions were planned. Interestingly, at the second visit at 18 months after the first biopsy, the size of the congenital melanocytic nevus was reduced with a peripheral whitish halo. Linear regression through suture lines and a peripheral halo was observed after the second and third serial excisions. The mechanism of the halo phenomenon remains elusive but is suggested theorized to be caused by destruction of melanocytes by immune responses of autoantibodies or cytotoxic T cells.

A pancreatic arteriovenous malformation (AVM) is a very rare disease entity that is usually asymptomatic; however, it may present with a massive gastrointestinal hemorrhage. Recent advances in cross-sectional imaging and the widespread availability of angiography have contributed to the diagnosis of this condition. A patient was transferred to our clinic due to unknown origin gastrointestinal bleeding and upper abdominal pain. Double balloon enteroscopy and duodenoscopy revealed a bleeding pancreatico-cholangio-duodenal fistula. We were able to diagnose an arteriovnous malformation with a pancreatico-cholangio-duodenal fistula by the use of angiography and from the post-operative pathological findings.

OBJECTIVE: Drug compliance is closely related to progress and prognosis of psychiatric disease. We investigated drug compliance in psychiatric outpatients and factors that influence their compliance. METHODS: Patients who visited a university hospital were asked about drug information and drug compliance using questionnaires. Medical records of the patients were reviewed. Demographic variables, clinical characteristics and drug compliance related variables were compared between non-compliance group and compliance group. Logistic regression analysis was performed to clarify predictors of poor compliance. RESULTS: One hundred eighty one patients participate in this study. 150 patients (82.9%) were compliance group, 31 patients (17.1%) were included in non-compliance group. Patient-related, illness-related and treatment-related factors, DAI total score and knowledge of side effect did not show any difference in both groups. However, illness severity was relatively higher in non-compliance group (p = 0.070) and patient's satisfaction about explanation of side effect was lower in noncompliance group (p = 0.061). Moreover, patients who negatively answered for question about negative recognition to psychiatric medication in DAI questionnaire were more common in non-compliance group (p = 0.075). In logistic regression, answering negatively to question about negative recognition to psychiatric medication in DAI questionnaire was related to non-compliance, but did not reached statistical significance (p = 0.086). CONCLUSION: This study suggests that improving negative recognition about psychiatric medication through drug education and good doctor patient relationship could enhance drug compliance.

BACKGROUND/OBJECTIVES: In this randomized, placebo-controlled, double-blind study, we evaluated the antihypertensive effects of enzymatic hydrolysate from Styela clava flesh tissue in patients with type 2 diabetes mellitus (T2DM) and hypertension. SUBJECTS/METHODS: S. clava flesh tissue hydrolysate (SFTH) (n = 34) and placebo (n = 22) were randomly allocated to the study subjects. Each subject ingested two test capsules (500 mg) containing powdered SFTH (SFTH group) or placebo capsules (placebo group) during four weeks. RESULTS: In the SFTH group, systolic and diastolic blood pressure decreased significantly 4 weeks after ingestion by 9.9 mmHg (P < 0.01) and 7.8 mmHg (P < 0.01), respectively. In addition, the SFTH group exhibited a significant decrease in hemoglobin A1c with a tendency toward improvement in homeostasis model assessment of insulin resistance, triglyceride, apolipoprotein B and plasma insulin levels after 4 weeks. No adverse effects were observed in other indexes, including biochemical and hematological parameters in both groups. CONCLUSION: The results of our study suggested that SFTH exerts a regulatory, antihypertensive effect in patients with T2DM and hypertension.
