The aim of this study was to evaluate the efficacy of platelet rich plasma (PRP) injections on the healing of chronic patellar tendinitis. We treated 44 patients affected by chronic patellar tendinitis. Lysholm, International Knee Documentation Committee, visual analogue scale score were used for clinical evaluation before, at the end of the treatment. A statistically significant improvement in all scores was observed at the end of the PRP injections in patients with chronic patellar tendinitis. The clinical results are encouraging, indicating that PRP injections have the potential to promote the achievement of a satisfactory clinical outcome to chronic patellar tendinitis.

Background: The goal of this study is to investigate the relationship between depression and glycated hemoglobin in the general Korean population. Methods: Adults aged 19 to 80 years were surveyed as part of the 2019 Korea National Health and Nutrition Examination Survey. A total of 4,831 people were chosen to complete the health questionnaire, provide their body mass index, and get a HbA1c blood test. The general characteristics of groups with high and low glycated hemoglobin were identified. To find out the correlation between depression diagnosis and the general population with high glycated hemoglobin, a chi-square test was carried out. A t-test was also used to compare the means of glycated hemoglobin between the groups diagnosed with and not diagnosed with depression. In analyzing the relationship between depression and glycated hemoglobin, analysis of covariance was performed by adjusting the effects for demographic factors. Results: Sex, age, income level, education level, drinking, smoking, exercise, and body mass index are all factors that influence glycated hemoglobin. The mean glycated hemoglobin was high in the group diagnosed with depression. The relationship between depression and glycated hemoglobin could not be confirmed using logistic regression after controlling for confounding variables. Conclusion There was no significant correlation between depression and glycated hemoglobin in the general population of Korea based on the results of this study.

Intravascular large B-cell lymphoma (IVLBCL) is a rare form of non-Hodgkin’s lymphoma that selectively involves the lumina of vessels, and may present as ischemic stroke. A 62-year-old man presented with progressive aphasia, dementia, seizure and stroke-like symptom. Brain magnetic resonance imaging revealed dynamic progressive fluid attenuated inversion recovery lesions and multiple punctate microbleeds in the bilateral subcortical region. A kidney biopsy revealed IVLBCL. We report a patient with IVLBCL presenting as rapidly progressive encephalopathy.

PURPOSE: Adjuvant radiotherapy of breast cancer using a photon tangential field incurs a risk of late heart and lung toxicity. The use of free breathing (FB), expiration breath hold (EBH), and deep inspiration breath hold (DIBH) during tangential breast radiotherapy as a means of reducing irradiated lung and heart volume was evaluated. METHODS: In 10 women with left-sided breast cancer (mean age, 44 years) post-operative computed tomography (CT) scanning was done under different respiratory conditions using FB, EBH, and DIBH in 3 CT scans. For each scan, an optimized radiotherapy plan was designed with 6 MV photon tangential fields encompassing the clinical target volume after breast-conserving surgery. RESULTS: The results of dose-volume histograms were compared using three breathing pattern techniques for the irradiated volume and dose to the heart. A significant reduction dose to the irradiated heart volume for the DIBH breathing technique was compared to FB and EBH breathing techniques (p<0.05). CONCLUSION: This study demonstrated that the irradiated heart volume can be significantly reduced in patients with left-sided breast cancer using the DIBH breathing technique for tangential radiotherapy.

PURPOSE: Hypoxia-inducible factor 1(HIF-1) is a transcriptional activator of genes whose products are involved in systemic, local, and cellular responses to hypoxia. We investigated the effect of androgen deprivation on the expression of HIF-1alpha and related proteins in the penile corpus cavernosum of castrated rat. MATERIALS AND METHODS: Thirty adult male Sprague-Dawley rats(250~350 gm) were divided into 3 groups of 10 each: sham operation(group 1), bilateral orchiectomy(group 2), and bilateral orchiectomy plus hormone replacement(group 3). Testosterone propionate(2 mg/day for 4 weeks) was used for hormone replacement. At 4 weeks after surgery, serum testosterone and erythropoietin were measured, and the expression of HIF-1alpha and VEGF were examined by immunohistochemical staining and Western blot of corpus cavernosum. RESULTS: There was no significant change in serum erythropoietin among the three groups. HIF-1alpha and VEGF immuno-positive cells were dense in vascular endothelium and cavernosal smooth muscle and showed more intense staining in the orchiectomy group compared with the control and sham operation groups. The amount of HIF-1alpha and VEGF proteins detected by Western blot were also increased in the orchiectomy group compared with the control and sham operation groups. CONCLUSIONS: These results suggest that increased HIF-1alpha expression in the penile tissue of castrated rat results from adaptive responses to hypoxia, and testosterone deprivation may contribute to hypoxic injury in the cavernosal microenvironment.

OBJECTIVE: In 2002, the Korean Society for Affective Disorders developed the guidelines for the treatment of major depressive disorder (MDD), and revised it in 2006 and 2012. The third revision of these guidelines was undertaken to reflect advances in the field. METHODS: Using a 44-item questionnaire, an expert consensus was obtained on pharmacological treatment strategies for MDD 1) without or 2) with psychotic features, 3) depression subtypes, 4) maintenance, 5) special populations, 6) the choice of an antidepressant (AD) regarding safety and adverse effects, and 7) non-pharmacological biological therapies. Recommended first, second, and third-line strategies were derived statistically. RESULTS: AD monotherapy is recommended as the first-line strategy for non-psychotic depression in adults, children/adolescents, elderly adults, patient with persistent depressive disorder, and pregnant women or patients with postpartum depression or premenstrual dysphoric disorder. The combination of AD and atypical antipsychotics (AAP) was recommended for psychotic depression in adult, child/adolescent, postpartum depression, and mixed features or anxious distress. Most experts recommended stopping the ongoing initial AD and AAP after a certain period in patients with one or two depressive episodes. As an MDD treatment modality, 92% of experts are considering electroconvulsive therapy and 46.8% are applying it clinically, while 86% of experts are considering repetitive transcranial magnetic stimulation but only 31.6% are applying it clinically. CONCLUSION: The pharmacological treatment strategy in 2017 is similar to that of Korean Medication Algorithm for Depressive Disorder 2012. The preference of AAPs was more increased.

PURPOSE: The purpose of our study was to compare the diagnostic value of contrast-enhanced spiral CT scanning and pulmonary angiography in detecting central and peripheral pulmonary embolism (PE) in pigs. MATERIALS AND METHODS: Experiments were performed in a porcine model of acute pulmonary embolism. Five pigs underwent contrast-enhanced spiral CT and pulmonary angiography after central venous administration of embolic material (Konyak). Three thoracic radiologists read the films and the results were compared with the findings of pathologic specimens. RESULTS: Of 85 cases of PE detected pathologically, 78 (91.8 %) were visible with spiral CT and 65 (76.5 %) with pulmonary angiography. Sensitivity and specificity for the detection of central emboli were 95 % and 100 %, respectively, with spiral CT, and 89 % and 100 %, respectively, with pulmonary angiography. Sensitivity and specificity for the detection of peripheral emboli were 88 % and 99 %, respectively, with spiral CT, and 64% and 100 %, respectively, with pulmonary angiography. CONCLUSION: Contrast-enhanced spiral CT is a very useful method for the diagnosis of both peripheral and central pulmonary embolism. Compared to pulmonary angiography its sensitivity and specificity are high.
