  • Purpose: The present study has an objective of effectively separating and making observations on a portion of radiopharmaceutical excreted via digestive organ to remain in the organ and invade a heart shadow. Materials and methods: When heart shadow is blocked by the organ in tests during a resting phase and a loaded phase, additional images were obtained using immobilization device. The immobilization devices were used to tilt the upper body forward from supine position. Results: In the reconstructed image for the separated case, as compared with the case where a part of organ is overlapped with heart, in terms of an overall mean value for each parameter, the end-diastolic volume increased by 2.75 mL, the end-systolic volume decreased by 3.16 mL, the left ventricle cardiac coefficient increased by 3.58%, and the area of defect region decreased by 3.58 and 3.92 cm for loading and resting phase, respectively. Conclusions: In the present study with myocardial perfusion SPECT, overlapped areas of heart and other organs could be effectively separated and visualization by the use of an immobilization device.

  • [ $Bi_2Sr_2Ca_nCu_{n+1}O_y(n{\geq}0)$ ] thin film is fabricatedvia two different processes using an ion beam sputtering method i.e. co-deposition and layer-by-layer deposition. A single phase of Bi2212 can be fabricated via the co-deposition process. While it cannot be obtained by the layer-by-layer process. Ultra-low growth rate in our ion beam sputtering system brings out the difference in Bi element adsorption between the two processes and results in only 30% adsorption against total incident Bi amount by layer-by-layer deposition, in contrast to enough Bi adsorption by co-deposition.

  • Prostate cancer is the most common malignancy in men in the United States. Surgery or radiation are sometimes unsatisfactory treatments because of the complications such as incontinence or erectile dysfunction. Selenium was found to be effective to preven prostate cancer in the Nutritional Prevention of Cancer Trial (NPC), which motivated two other clinical trials: the Selenium and Vitamin E Cancer Prevention Trial (SELECT) and a Phase III trial of selenium to prevent prostate cancer in men with high-grade prostatic intraepithelial neoplasia. However, these two trials failed to confirm the results of the NPC trial and indicated that the selenium may not be preventive of prostate cancer. In this article we review the three clinical trials and discuss some different points which might be potential factors underlying variation in results obtained.

  • Indigestion is one of the most frequent symptom in chronic hepatitis. We treated a 20 year-old female patient of chronic active hepatitis type B with Sengangeonbi-tang. The patient complained indigestion and constipation. The serum aminotransferase were higher and viral marker showed hepatitis was in active phase. 1 week later, the symptom had been changed from severe to mild and aminotransferase decreased. We continued to prescribe the medicine 2 weeks more and could observe that the symptom disappeared and the aminotransferase fell down under normal value with no side effect. Sengangeonbi-tang showed desirable effect on indigestion and more rapid recovery of aminotransferase than previous reports about treating hepatitis.

  • Nuclear medicine imaging is widely used in pain medicine. Low back pain is commonly encountered by physicians, with its prevalence from 49% to 70%. Computed tomography (CT) or magnetic resonance imaging (MRI) are usually used to evaluate the cause of low back pain, however, these findings from these scans could also be observed in asymptomatic patients. Bone scintigraphy has an additional value in patients with low back pain. Complex regional pain syndrome (CRPS) is defined as a painful disorder of the extremities, which is characterized by sensory, autonomic, vasomotor, and trophic disturbances. To assist the diagnosis of CRPS, three-phase bone scintigraphy is thought to be superior compared to other modalities, and could be used to rule out CRPS due to its high specificity. Studies regarding the effect of bone scintigraphy in patients with extremity pain have not been widely conducted. Ultrasound, CT and MRI are widely used imaging modalities for evaluating extremity pain. However, SPECT/CT has an additional role in assessing pain in the extremities.

  • Fever has been recognized as a cardinal feature of disease since antiquity, but only recently has the pathophysiology of fever come to be understood. It became clear that the ultimate cause of fever is not a bacterial product (a so-called exogenous pyrogen) but a product of host inflammatory cells (i.e., an endogenous pyrogen). Many studies have demonstrated that mononuclear phagocytes are the principal source of endogenous pyrogen and that a variety of mononuclear cell products can mediate the febrile response. Cytokines are also important as mediators of the acute-phase response to infection and inflammation.

  • birth-weight infants during the recovery phase of respiratory distress syndrome and has been associated with long-term pulmonary sequelae. The importance of surgical and medical abolition of left-to-right shunting in symptomatic neonates is established. Four preterm infants with birth weights under 1, 500gm with a PDA unresponsive to pharmacological closure underwent ligation. Two of preterm infants survived to be discharged and are developing normally. One infant has died due to respiratory distress syndrome, septicemia and necrotizing enterocolitis during hospital stay and other infant died due to septicemia after hospital discharge with follow-up for 6 months.

  • Benign acute childhood myositis (BACM) is a rare transient condition that occurs in children during the early convalescent phase of a viral upper respiratory infection. BACM is self-limiting and characterized by sudden-onset bilateral calf pain that leads to difficulty in walking. We report a case of a 5-year-old boy with BACM who presented with acute-onset bilateral calf pain after a resolved episode of viral pharyngitis and subsequently refused to walk. With conservative treatment, the patient recovered completely after approximately 1 week. Although perplexing and challenging for clinicians unfamiliar with BACM, awareness of this rare clinical condition is essential to preventing unnecessary investigations and reassuring the patient and parents of its excellent prognosis.

  • Despite medical and invasive advancements, cardiovascular mortality attributable to ischemic heart disease, including acute coronary syndrome (ACS), persists at a substantial level. Clinical guidelines have been issued by the European Society of Cardiology (ESC) and American College of Cardiology/American Heart Association to support clinicians in making appropriate decisions and improving the prognosis of ACS patients. ESC recently introduced a new ACS guideline in August 2023. This review discusses the recent modification in the diagnosis and management of early-phase ACS in the 2023 ESC guideline.
