Purpose: The Gated cardiac blood pool scan is non-invasive method that a quantitative evaluation of left ventricular function. Also this scan have shown the value of radionuclide ejection fraction measurements during the course of chemotherapy as a predictor of cardiac toxicity. Therefore a reliable method of monitoring its cardiotoxic effects is necessary. the purpose of this study is to minimize the overestimate of left ventricular ejection fraction (LVEF) by modified body position to reduce the influence of scattered rays from surrounding organs of the heart in the background region of interest. Materials and Methods: Gated cardiac blood pool scan using in vivo $^{99m}Tc$-red blood cell (RBC) was carried out in 20 patients (mean $44.8{\pm}8.6$ yr) with chemotherapy for a breast carcinoma. Data acquisition requires about 600 seconds and 24 frames of one heart cycle by the multigated acquisition mode, Synchronization deteriorates toward the end of the cycle and with the distance from the trigger signal (R-wave) by ECG gating. Gated cardiac blood pool scan was studied with conventional method (supine position and the detector head in $30-45^{\circ}$ left anterior oblique position and caudal $10-20^{\circ}$ tilt) and compared with modified method (left lateral flexion position with 360 mL of drinking water). LVEF analysis was performed by using the automatically computer mode. Results: The ROI counts of modified scan method were lower than LV conventional method ($1429{\pm}251$ versus $1853{\pm}243$, <0.01). And LVEF of modified method was also decrease compared with conventional method ($58.3{\pm}5.6%$ versus $65.3{\pm}6.1%$, <0.01). Imaging analysis indicated that stomach was expanded because of water and spleen position was changed to lateral inferior compared with conventional method. Conclusion: This study shows that the modified method in MUGA reduce the influence of scattered rays from surrounding organs. Because after change the body position to left lateral flexion and drinking water, the location of spleen, left lobe of liver and stomach had changed and they could escaped from background ROI. Therefore, modified method could help to minimize the overestimate LVEF (%).

This study is designed to report three cases of postoperative care after hip surgery using conventional Korean Medicine treatments including phototherapy. Three patients undergone hip fracture surgery were treated with acupuncture, herbal medicine, and phototherapy. We used Visual analogue scale (VAS), EuroQol five dimension scale (EQ-5D), and hip disability and osteoarthritis outcome score (HOOS) to evaluate treatment effectiveness. After the treatment, VAS score was improved in all three cases, while EQ-5D and HOOS showed different results by items. EQ-5D (pain/discomfort) and HOOS (pain, symptoms, activities of daily living) were improved in all three cases. EQ-5D (self-care) and HOOS (quality of life) showed improvements in two cases. EQ-5D (mobility, usual activities, anxiety/depression) and HOOS (sports/recreation) were improved in one case. Conventional Korean Medicine treatments including phototherapy can be effectively used to alleviate pain and symptoms after hip fracture surgery.

Objectives: Sarcopenia is an age-associated skeletal muscle disorder that can profoundly impact the health of elderly people. However, the efficacy of herbal medicine in sarcopenia is uncertain. This review aims to investigate evidence of the effect of herbal medicine on sarcopenia. Methods: We systematically searched 12 electronic databases for relevant randomized controlled trials (RCTs). Only trials that met the inclusion criteria were selected, and the characteristics of the included studies were extracted and synthesized in a narrative manner. The quality of the included studies was assessed using Cochrane's Risk of Bias (RoB) 2.0 tool. Results: 7 RCTs involving 672 participants with sarcopenia met the inclusion criteria. The intervention combining herbal medicine and conventional treatment (i.e., exercise, nutritional support) had a significant therapeutic effect compared with the conventional treatment, showing improvement in muscle strength (i.e., grip strength), muscle mass (i.e., appendicular skeletal muscle mass index), and physical function (i.e., gait speed, short physical performance battery, and timed up and go test). However, the methodological quality of the included RCTs was relatively low due to their high RoB, making it difficult to evaluate the efficacy of herbal medicine in sarcopenia. In terms of safety, several adverse events were reported. Conclusion: This review suggests that herbal medicine has a positive effect on muscle strength, muscle mass, and physical performance in elderly patients with sarcopenia, but there is a clear need for further research in this area.

Because US plays a key role in the initial evaluation of hepatic hemangiomas, knowledge of the entire spectrum of US appearances of these tumors is important. Most hemangiomas have a distinctive US appearance, and even with those with atypical appearances on conventional gray-scale US, specific diagnoses can be made using pulse-inversion harmonic US with contrast agents. In this essay, we review the spectrum of US appearances of hepatic hemangiomas on conventional gray-scale, power Doppler, and pulse-inversion harmonic US with contrast agents.

This study was aimed to obtain epidemiological information of cancer patients treated with Oriental medicine. 58 breast and gynecological cancer patients treated in Cancer Center of Daeguhanny Oriental Hospital from August 2012 to August 2013 were reviewed. Careful investigations were done by categorizing these patients by their origin, stage, treatment, conventional treatment type, chief complaint, etc. In tumor origin, breast cancer showed the largest proportion in total patients(74.1%) and inpatients(81.8%). 63.8% of the patients' tumors were stage III and IV. 48.3% of patients visited Oriental hospital for combination treatment with conventional medicine. 91.4% of the patients have under 5 years of cancer duration. Their cheif complaints are general weakness, postoperative pain and abdominal discomfort in general. This study presented the characteristics of breast and gynecological cancer patients treated by Oriental medical therapies, and thus would be valuable for futher studies of Oriental medical cancer treatments.

Modified rush immunotherapy (IT), by combination of rush IT and conventional IT, provides a faster method to reach maintenance dose, leading to higher patient adherence when compared with conventional IT, decreasing systemic adverse reactions when compared with a standard rush IT. Ten atopic dogs of this study include fulfillment of Favrot's criteria. Offending allergens were identified by the use of IDST. During the induction period, the dogs were received a total of 10 injections. Five injections were administrated every 30 minutes in a day with gradually increasing amounts and concentrations of allergens, and the last 5 injections were administered every 3 days. The efficacy of 10-injection induced mRIT was assessed using the canine atopic dermatitis extent and severity index (CADESI). During maintenance period, reduction rate from baseline scores varied between 3.2% and 60.9% and the after 6 months of therapy for CADESI-03 score in 6 of the 10 dogs. Adverse reactions were not observed in these dogs during induction period by mRIT with 10 injections. Based on these results, our modified rush IT protocol is considered to be a useful protocol to treat canine atopic dermatitis.

Computed tomography with virtual bronchoscopy shows inner shape of trachea and major bronchi with three-dimensional images. Virtual bronchoscopy can be used in cases of suspected foreign body aspiration. Virtual bronchoscopy shows the exact location of the obstructive lesion before conventional bronchoscopy. If the chest radiography is normal or suggests aspirated foreign body, virtual bronchoscopy can be considered before conventional bronchoscopy. We experienced a case of false-tooth foreign body extracted under bronchoscopy. In this case, virtual bronchoscopy was made retrospectively giving useful information about shape and orientation regarding foreign body.

In this paper, we propose a method to measure respiration rate by dividing the respiration related region in depth image using level set method. In the conventional method, the respiration related region was separated using the pre-defined region designated by the user. We separate the respiration related region using level set method combining shape prior knowledge. Median filter and clipping are performed as a preprocessing method for noise reduction in the depth image. As a feasibility test, respiration activity was recorded using depth camera in various environments with arm movements or body movements during breathing. Respiration activity was also measured simultaneously using a chest belt to verify the accuracy of calculated respiration rate. Experimental results show that our proposed method shows good performance for respiration rate estimation in various situation compared with the conventional method.
