  • The present study was purposed to evaluate the incidence and the characteristics of metastatic "cold" lesions in $^{99m}Tc$-MDP bone scans of adult patients with solid malignancies. There were 29 cold lesions in 24 patients. The incidence of cold lesions was about 1% of total cases of bone scans for the patients with malignancy, or 2.5% of cases with bone metastases. Th primary sites of malignancies were lung (four cases), uterine cervix (three cases), kidney, nasopharynx, thyroid, urinary bladder, prostate, lymphoma (two cases each other), liver, breast and others (one case each other). But the relative incidence of cold lesion in lung cancer and breast cancer was low. The most frequent site of cold lesion was spine, and pelvis, skull and rib were followed. The incidence of cold lesion was related to the regional incidence of bone metastases. The size of the cold lesions was greater than that of the hot. There were six cases of single cold lesion without any other abnormalities and two cases of cold lesion which were initially hot. So it should be considered that bone metastases might be presented as cold lesions in bone scan.

  • A 26-year-old man with renal cell carcinoma underwent $^{99m}Tc$-HDP bone scintigraphy for detecting bony metastasis after left total nephrectomy for renal cell carcinoma. $^{99m}Tc$-HDP bone scintigraphy showed small hot lesion in the first lumbar spine. About 12 months later, he underwent spinal MRI for lower back pain. A large mass was seen around spinous process of the first lumbar spine (L1) on spinal MRI and confirmed as metastatic renal cell carcinoma by bone biopsy. $^{99m}Tc$-HDP bone scintigraphy and $^{18}F$-FDG PET/CT were underwent for further evaluation. $^{99m}Tc$-HDP bone scintigraphy showed cold lesion in the first lumbar spine which was initially hot and newly developed hot lesion in the twelfth thoracic spine, and which were shown as hypermetabolic lesions in $^{18}F$-FDG PET/CT. We report a case of bony metastasis from renal cell carcinoma which is changed from hot lesion to cold lesion in $^{99m}Tc$-HDP bone scintigraphy and compare with $^{18}F$-FDG PET/CT.

  • Acute osteomyelitis is usually shown as a localized area of increased activity (hot uptake) in the infectious focus on bone scintigraphy. In our patient, absence of radioactivity (cold lesion) was noted in the distal metaphyseal and diaphyseal regions of his right femur. Initial x-ray was interpreted as normal except for mild soft tissue swelling in the right thigh. The lesion was confirmed as an acute osteomyelitis with subperiosteal abscess on surgery. Staphylococcus aureus was the etiologic organism. We describe a case of acute osteomyelitis in a one-year-old boy shown as a cold lesion on bone scan.

  • Among 2,373 slaughtered pigs examined for one year(March 1995 to February 1996), 1,899 pigs had visible pulmonary lesions. Prevalence rate of pulmonary lesion was examined by pathological techniques according to rearing and health managements of pig farms. The results were as follows : 1. Prevalence rate of pulmonary lesion in all-in/all-out flow farms(71.9%) was lower than that in continous flow farms(85.2%). 2. Prevalence rate of pulmonary lesion in non-infected farms with Aujeszky's disease virus and/or porcine reproductive and respiratory syndrome virus(74.4%) was lower than that in infected farms(85.5%). 3. During winter, prevalence rate of pulmonary lesion in farms with cold-control facilities(83.2%) was lower than that in farms with poor cold-control facilities.

  • The main current in the pathology of oriental medicine is composed of etiologic factor, pathogenesis and clinical manifestation. The access of a disease is consist of etiologic factor, location of the lesion, nature of the disease and patient's condition. The nature of disease and the property of a drug are inseparably related to each other. The nature of disease is composed of six exogenous factors, cold and heat, deficiendy and excess, Yinyang and pain. Cold nature is divided into cold symptom due to excess and asthenia cold, fever nature is divided into sthenic fever and asthenic fever. According to the location, cold and heat can be subdivided into heat in the upper and cold in the lower, cold in the upper and heat in the lower, exterior cold and interior heat, exterior heat and interior cold. Yin syndrome characterized by hypofunction of the viscera is generated from insufficiency of yang-qi, excess of yin-coldness, deficiency of both qi and the blood.

  • Cold atmospheric plasma (CAP) is a material that generates free radicals through the ionization of air. Despite the application in various medical fields, the efficacy and safety of CAP on post-inflammatory hyperpigmentation due to atopic dermatitis have not been reported. Herein, we report the improvement in post-inflammatory hyperpigmentation of atopic dermatitis, after CAP treatment of three sessions weekly, 10 minutes per session. We examined the clinical severity indexes before and after treatment, including the Investigator's Global Assessment, modified Atopic Dermatitis Antecubital Severity, Eczema Area and Severity Index, and pruritus visual analogue scores. Our results indicate that CAP alleviates the post-inflammatory hyperpigmentation and clinical severity of atopic dermatitis, and effectively improves the atopic skin lesion without severe safety issues. We believe that the previously reported anti-bacterial effects and production of interleukin-6 after CAP treatment are probably responsible for the underlying mechanisms leading to clinical improvement.

  • Objectives: Dysphagia is a common in stroke patients. Dysphagia often affects the rehabilitation of stroke patients by increasing the risk of nutritional deficits and aspiration pneumonia. Despite the proliferation of physical therapies including swallowing training, much controversy remains regarding the application and benefit of them. Therefore, in this study, the clinical effect of moxibustion at Chonjung(CV17, Shanzhong) on post-stroke dysphagia were assessed using Swallowing Provocation Test(SPT). Methods: Dysphagia subjects were selected by Dysphagia Screening Test. Swallowing function was tested by Swallowing Provocation Test(sec). Direct moxibustion was applied to the acupoint, Chonjung, five times and Swallowing Provocation Test was performed before and after 30 minute. The Latency Time of Swallowing Reflex (LTSR) was checked by SPT. To find factors related with improving swallowing function, Cold-Heat and Excess-Deficiency Diagnosis were considered. Results: A total of 42 patient were included, but two of them were excluded due to severe coughing. Overall, the swallowing reflex improved significantly. In subgroup analysis on brain lesion, non-brain stem lesion patients significantly improved. Moxibustion was more effective in the cold group than in the heat group, but there were no differences between the Excess and the Deficiency groups. Conclusions: The result of this clinical study suggest that moxibustion at Chonjung(CV17, Shanzhong) is an effective treatment for the dysphagia patients after stroke, especially in non-brain stem lesion and the cold diagnosed patients.

  • Endoscopic submucosal dissection (ESD) is the standard treatment method for esophageal, gastric, and colorectal cancers. However, it has not been standardized for duodenal lesions because of its high complication rates. Recently, minimally invasive and simple methods such as cold snare polypectomy and underwater endoscopic mucosal resection have been utilized more for superficial nonampullary duodenal epithelial tumors (SNADETs). Although the rate of complications associated with duodenal ESD has been gradually decreasing because of technical advancements, performing ESD for all SNADETs is unnecessary. As such, the appropriate treatment plan for SNADETs should be chosen according to the lesion type, patient condition, and endoscopist's skill.

  • After four years of cold storage, dimethachlon resistance of two laboratory-induced resistant Sclerotinia sclerotiorum isolates SCG7 and LA50 declined by 99.5% and 98.9%, respectively, and cross resistance to iprodione and procymidone also declined dramatically. Along with the decline of fungicide resistance, osmotic sensitivity to sodium chloride and glucose decreased tremendously; mycelial growth rate, sclerotia number and weight per potato dextrose agar (PDA) plate increased on average by 118.6%, 85. 5% and 64.5%, respectively; and virulence to detached leaves of oilseed rape increased by 72.7% on average. Significant negative correlations were detected between dimethachlon resistance levels and mycelial growth rate on PDA (r = -0.980, P = 0.021), and between resistance levels and lesion diameters on detached leaves of oilseed rape plants (r = -0.997, P = 0.002). These results have profound implications for assessing the potential risk for resistance development to dicarboximide fungicides in S. sclerotiorum.
