Objectives: The purpose of this study was to research the demographical and gynecologic characteristics, quality of life, and analyze the pattern identification in female patients with cold hypersensitivity of hands and feet. Methods: 112 participants were recruited from May 2018 to April 2019 from three korean medical hospitals. The data was composed of general characteristics, degree of coldness of hands and feet, gynecological questionnaire, score of WHOQOL-BREF and pattern identification. We divided data into 2 groups: The group of patients who meet the criteria for diagnosis of coldness on feet and the group of patients who meet the criteria for diagnosis of coldness on feet and hands. We tried to compare data by groups using Excel 2016 for windows and SPSS for windows (Ver. 23.0). Results: Throughout the study, we found differences between 2 groups in weight, body mass index (BMI), VAS score of cold hypersensitivity on feet, temperature of PC8, ST32, and pattern identification. Conclusions: After the study, we confirmed that even though both groups suffer from cold hypersensitivity of hands and feet, they show clinical differences in each group and differences in pattern identification.

Objectives : This study aimed to investigate the relationship between cold feet and sleep quality using polysomnography (PSG) and Pittsburgh Sleep Quality Index (PSQI). Methods : We divided 11 adults (6 females, 5 males) with Insomnia Severity Index score below 21 into cold feet (CF) and a non-cold feet (NCF) group based on the median feet temperature (Taichong, LR3). PSG and PSQI were administered to assess sleep characteristics and subjective sleep quality. Results : CF group exhibited significantly lower time in bed, sleep period time, and total sleep time compared to NCF group. While there were no significant group differences in sleep latency, wakefulness after sleep onset, or total arousal index, NCF group had significantly lower minimum oxygen saturation and apnea-hypopnea index in REM (rapid eye movement) sleep compared to CF group. Although the PSQI score and the proportion of poor sleepers were both higher in the CF group (7.40 and 80%) compared to the NCF group (5.50 and 50%), these differences did not reach statistical significance. Conclusions : This study showed that foot temperature affects sleep characteristics and suggests the need to utilize PSG in sleep research in Korean medicine.

Objectives: This study was aimed to figure out the effect of Onkyung-tang (OKT) on cold hypersensitivity on feet in female patients. Methods: This study was designed to implement multi-center randomized clinical trial in three korean medical hospitals. The female patients who were enrolled in this study were 112 women who suffered from cold hypersensitivity on feet. They were randomly allocated into OKT group or control group in 1:1 ratio. The primary outcome was change in score of visual analogue scale of hypersensitivity on feet, and the secondary outcomes were thermometer of LU4, PC8, ST32, LR3, visual analogue scale of hypersensitivity on hands, result of cold stress test, and score of World Health Organization Quality of Life-BREF. Results: In both group, the VAS of hypersensitivity on feet and hands was decreased while taking the medicine, and the effect of decreasing the VAS continues for the 4 weeks after the end of medication (p<0.001, 0.003, 0.001). In OKT group, the body temperature difference in lower extremity (ST32-LR3) was steadily decreased at every visit and it was statistically significant(p=0.003, <0.001). On the other hand, in control group, the body temperature difference in lower extremity was decreased only while taking the medicine (p<0.001). Conclusions: OKT significantly reduced discomfort coldness on feet in patients, and the effect of treatment was maintained at least for four weeks after medication.

Cold hypersensitivity is the condition with unusual cold sensitivity at temperature when others don't feel so. It is not disease in itself, but is known as having relationship with infertility, dysmenorrhea, anemia and endocrine disorder. The symptoms of cold hypersensitivity appear on limbs and abdomen especially, and may affect bowel movement such as constipation or diarrhea. We made a research of 86 healthy young girls who took medical examination and examined subjective bowel habit. The patients were divided into three group by defecation type, constipation(42), diarrhea(14) and normal group(30). Temperature differences$({\Delta}Ts)$ measured by DITI on upper and lower abdomen of each group had not statistically significance. Otherwise ${\Delta}Ts$ between upper arm and palm and between upper leg and foot were statistically signigicant. The severity of cold hypersensitivity on hands was in order constipation, normal and diarrhea group, and same as feet. The diarrhea patients had more severe cold hypersensitivity as compared with constipation patients. Correlation between ${\Delta}Ts$ on abdomen and hands or feet didn't exist. ${\Delta}Ts$ on hands and feet, however, had positive relationship. This research showed cold hypersensitivity could be related with diarrhea.

Background: Cold hypersensitivity (CH) and sleep disorders are not limited to patients with specific diseases, as they are also commonly observed in the general population. The objective of this study was to investigate the relationship between CH and sleep quality. Methods: This cross-sectional study analyzed data from a cohort of 5,052 individuals living in South Korea. Based on the results of a questionnaire on CH, the participants were classified into four groups: non-CH, CH in the hands (CHH), CH in the feet (CHF), and CH in the hands and feet (CHHF). Sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI). Multiple regression was used for groupwise comparisons of total PSQI scores and the scores for each component, and logistic regression was used to find the odds ratios of being a "poor sleeper" (PSQI≥8.5). Results: The CHF and CHHF groups showed significantly higher scores than the non-CH group on the overall PSQI as well as on the following sleep components: subjective sleep quality, sleep latency, habitual sleep efficiency, sleep disturbance, and sleep medication use. The odds ratios for being a "poor sleeper" were significant in the CHF (1.84; CI=1.38-2.43) and CHHF groups (1.54; CI=1.25-1.89), but the CHH group did not show any difference from the non-CH group. We identified a correlation between CH in the feet and poor sleep quality. Conclusions: These findings help to elucidate the relationship between sleep and CH and highlight the need to clarify the underlying mechanism.

This study of purpose was to evaluate the changes in hands and feet temperature by applying massage and paraffin bath.. The subject of this study was 30 university healthy students. Subjects were divided into paraffin bath group and massages group. The digital infrared thermographic imaging was used for thermographic analysis. The visual analog scale was used for subjective information about the degree of cold sensitivity and cold stress test was used for analyzing the temperature recovery rate. After the interventions showed that temperature difference of the right hand and temperature difference of the left hand are less in the paraffin group than the massage group. When applied paraffin bath and massage to the cold hypersensitivity patient the massage group showed difference in the visual analog scale and the paraffin group showed difference in the temperature of the right hand, left hand, left foot and in the visual analog scale. Paraffin bath treatment seems to be useful to patients with cold hypersensitivity on hands and feet.

This study was conducted to determine the effect of duck feet gelatin concentration on the physicochemical, textural and sensory properties of duck meat jellies. Duck feet gelatin was prepared with acidic swelling and hot water extraction. In this study, four duck meat jellies were formulated with 3, 4, 5, and 6% duck feet gelatin, respectively. In the preliminary experiment, the increase in duck feet gelatin ranged from 5 to 20%, resulting in a significant (p<0.001) increase in the color score, but a decline in the hardness and dispersibility satisfaction scores. An increase in the added amount of duck feet gelatin contributed to decreased lightness and increased protein content in duck meat jellies. Regarding the textural properties, increase in the added amount of duck feet gelatin highly correlated with the hardness in the center (p<0.01, $R^2=0.91$), and edge (p<0.01, $R^2=0.89$), of duck meat jellies. Meanwhile, the increase in duck feet gelatin decreased the score for textural satisfaction; duck meat jellies containing 6% duck feet gelatin had a significantly lower textural satisfaction score, than those containing 3% duck feet gelatin (p<0.05). Furthermore, a significant difference in the overall acceptance of duck meat jellies formulated with 5% duck feet gelatin was observed, as compared to those prepared with 3% duck feet gelatin. Therefore, this study suggested that duck feet gelatin is a useful ingredient for manufacturing cold-cut meat products. In consideration of the sensory acceptance, the optimal level of duck feet gelatin in duck meat jellies was determined to be 5%.
