The purpose of this study was to identify correlation of stress, coping patterns and physical symptoms in cancer patient's caregiver. The stress was measured by VAS(Visual Analogue Scale). The coping methods were measured using the modified Ways of Coping Questionnaire by Yang (1998) and the actual physical symptoms were investigated. The phases of patient illness consisted of 1st (initial) stage, and 2nd (recurred) stage and 3rd (terminal) stage based on literature (Lewandowski & Jones, 1988). The data were collected by a survey conducted from March to July, 2000 and which included 196 cancer patients' caregivers from two hospitals in Seoul. The data were analyzed using paired t-test, unpaired t-test, ANOVA, Scheffe test and Pearson correlation coefficient. The results were as follows: 1. The average of caregivers' stress scores was 62.5. Problem-focused coping methods were significantly used more than emotion-focused coping methods by the cancer patients' caregiver. The mean number of caregivers' physical symptom was 1.03. 2. There were significantly high level of stress in women, those who were more than 60 years old, those who had a low education level, those who had no job, those who are patients' wives' and those who are terminal patients' caregiver. There were significantly low levels of coping in women, those who were more than 60 years old, those who had low education levels, those who had no job and those who are patients' wives. There were significantly higher number of physical symptoms in women, and those who have no job. 3. Caregivers' stress was significantly correlated to problem-focused coping methods (r=-.21, p=.006), and physical symptom (r=-.28, p=.0001). In conclusion, attempts to develop nursing interventions for cancer patients' caregiver in women, those who are more than 60 years old, with a low education level, have no job, and are cancer patients' wives could have an improvement on positive coping methods and provide relaxation from stress in the patients' experience.

Although the number of foreign patients visiting Korea for medical treatments or plastic surgery is rapidly increasing, countermeasures against unforeseen medical disputes involving foreign patients are adequate. To date, the record shows that most foreign patients have visited doctors at the departments of family medicine, internal medicine, dermatology (incl. plastic surgery), and healthcare centers, which, fortunately, indicates that there are not many severe, high risk patients. However, if the current growth rate continues to rise and the number of foreign patients visiting each department continues to grow, more diverse medical practices will be likely to take place in the future, and consequently, it is expected that the possibilities of medical malpractice and the costs of dispute resolution will also rise dramatically. When a medical dispute occurs, in general, a lawsuit is ultimately settled by the court. However, since this can damage the creditworthiness of medical institutions and also incur significant litigation costs, which is a typical characteristic of a medical lawsuit, medical professionals or institutions will be heavily burdened. Furthermore, an adequate policy or countermeasure against a medical dispute with a foreign patient has not yet been established, and it would be difficult to resolve a dispute by finding the middle ground, due to relative standards and policies between countries. Now, we need to improve the existing policies and prepare for countermeasures that will allow us to precisely predict the nature of such disputes, which have been increasing, and resolve them peacefully. Based on such knowledge, this study aims to establish countermeasures against medical disputes with foreign patients, and examine ways to promptly and reasonably resolve them at an early stage.

This study was conducted to find out basic information on better customer satisfaction and service by examining and analyzing in what routes patients mostly have selected their dental medical organizations and how they have reacted to their dissatisfaction. The subject of study included the patients who have come to dental clinics and dental hospitals to be treated in Cheonan City, Chungnam and the researcher of this study used a survey and analyzed its gathered data using an SPSS(Statistical Package for the Social Science) WIN 11.5 Program. As analysis methods, frequency and percentage were calculated to figure out the general characteristics of its subject. In addition, a ${\chi}^2$(Chi-square) test was performed to figure out the factors that patients have selected their dental medical organizations and the following results were obtained. 1. The largest number of patients selected their dental medical organizations by hearsay and more female and married patients selected them by hearsay than other patients, and there were significant differences(p<.05). 2. The dental patients put the priority on treatment techniques in their visiting hospitals and the patients who were more than 40 years old and married patients put more emphasis on treatment techniques in their visiting hospitals than other patients and there were significant differences(p<.05). 3. The said dental patients were not satisfied with the kindness of medical staffs in their visiting medical organizations; meanwhile, the patients who were aged below 30 and had an academic background of more than university degree and were unmarried were less satisfied with the kindness of medical staffs in their visiting medical organizations than other patients and there were significant differences(p<.05). 4. In terms of improvement methods or complaints, the largest number of them said that they just ignored and endured; meanwhile, the patients who were aged below 30 and had an education of more than university degree and were unmarried were more patient of improvement methods or complaints than other patients and there were significant differences(p<.05). 5. There were more patients who have introduced their visiting medical organizations to their neighboring people than the patients who have not done it; in the meantime, the patients who were aged over 40 and were married have introduced their visiting medical organizations to their neighboring people more than other patients(p<.05).

Background Abdominal wall free flaps are used most frequently in autologous breast reconstruction, and these flaps require intact and robust deep inferior epigastric perforator (DIEP) vessels. Pfannenstiel incisions are often present during preoperative visits for breast reconstruction and could potentially signal compromised blood supply to the lower abdominal wall. In this study, we compared the number of DIEP vessels between patients with and without Pfannenstiel incisions undergoing autologous breast reconstruction. Methods A retrospective review of medical records was performed for patients with (study) and without (control) Pfannelstiel incisions (n=34 for each group) between June 2010 and July 2013. In addition to patient demographics, number of caesarian sections, and outcomes of free flap reconstruction, abdominal wall vasculature was compared using the preoperative computed tomography angiographic data between the groups. For each patient, vessels measuring greater than 1 mm were counted and divided into four sections of the lower abdominal wall. Results The mean number of perforator vessels was 10.6 in the study group and 11.4 in the control group, which was not statistically different (P=0.575). Pfannenstiel incisions with history of repeat caesarian sections were not associated with decreased number of perforator vessels. Conclusions Pfannenstiel scars are associated with neither a change in the number of DIEP vessels nor decreased viability of a free transverse rectus abdominis myocutaneous and DIEP flap. Lower abdominal free flaps based on DIEP vessels appear safe even in patients who have had multiple caesarian sections through Pfannenstiel incisions.

Purpose: With the necessity of comprehensive care for the breast cancer patients, Breast Care Center of our hospital started to work in March 2004. This study examined the 3-year execution of Breast Care Center. The role of Breast Care Center was evaluated in aspect of clinical activities in quality and quantity. Methods: A retrospective review was carried out from 2001 to 2007 with breast cancer patients. The number and type of breast cancer surgery and breast reconstruction procedure were compared before and after Breast Care Center's foundation. Time required for the diagnosis and treatment was also compared. Regression analysis and T-test were used to identify the statistical significance. Results: The number of breast cancer surgery did not statistically increase compared with progressive increase of breast cancer. QUART(quadrantectomy, axillary dissection, radiotherapy) procedure statistically significantly increased and MRM(Modified Radical Mastectomy) procedure decreased for breast cancer surgery after foundation of Breast Care Center. The number of breast reconstruction procedures statistically significantly increased. The number of immediate TRAM free flap (Transverse Rectus Abdominal muscle free flap) procedures has grown 3.8 times after foundation of Breast Care Center. The time required for diagnosis and treatment was also shortened. Conclusion: After foundation of Breast Care Center, the number of breast reconstruction surgery increased, while the counselling time in breast reconstruction was reduced. Breast Care Center provided a prompt and comprehensive care to the breast cancer patients through the multidisciplinary therapeutic approaches.

Background: Accessory infraorbital foramen (AIOF) can change the normal course of emerging branches of the infraorbital nerve and blood vessels exiting the infraorbital foramen (IOF). This study aimed to examine the AIOF, number of foramina, and their position in relation to IOF using cone-beam computed tomography (CBCT). Methods: We performed a retrospective CBCT assessment of hospital records between January 2018 and August 2022. The CBCT of 507 patients were examined to extract information on the prevalence, number, position, linear distance from the IOF, and diameter of AIOF in relation to demographic factors. Descriptive statistics were used to evaluate the prevalence of AIOF. Mean and standard deviation were used to calculate the linear distance and diameter of the AIOF, respectively. The AIOFs, its distribution, and number were compared between sexes and sides using the chi-square test. The independent t-test and Mann-Mann-Whitney test were used to compare the mean difference between the sexes and sides. Statistical significance was set at P < 0.05. Results: In this current study, the prevalence of AIOF was 7.1% (36 of the 507 patients). Additionally, the current study examined the number of foramina using a single foramen on each side and double foramina located bilaterally at a distance from the AIOF to the IOF. The mean AIOF diameter was also studied, and the AIOF position with respect to the IOF on CBCT was superomedial or inferomedial. There were no statistically significant associations between any of the parameters assessed in this study when comparing sex and sides. Conclusions: A greater number of patients with AIOF presented with a single foramen and unilateral occurrence, without a statistically significant difference. The AIOF was most commonly located superomedial to the IOF.

Background: Video-assisted thoracoscopic surgery (VATS) lobectomy has become the major surgical option for the treatment of non-small cell lung cancer (NSCLC). Endoscopic instruments such as stapler cartridges are essential for VATS procedures. In this study, we investigated the factors that affect the number of stapler cartridges used in VATS lobectomy. Methods: A retrospective analysis was conducted of patients who underwent complete VATS lobectomy for NSCLC from January 2013 to December 2015. Results: In total, 596 patients underwent complete VATS lobectomy. The average number of stapler cartridges used for VATS lobectomy was 5.3±1.9. The number of stapler cartridges used for VATS lobectomy was higher in men (5.5±1.9 vs. 5.0±18, p=0.006), those aged older than 70 years (5.5±2.1 vs. 5.1±1.7, p=0.038), those who underwent upper or middle lobectomy procedures (5.7±1.9 vs. 4.1±1.2, p<0.001), those with a higher fissure sum average (p<0.001), and those in whom surgery was performed by a surgeon with a preference for staplers (5.6±2.0 vs. 4.9±1.6, p<0.001). Conclusion: The number of stapler cartridges required to perform VATS lobectomy in NSCLC patients appears to be influenced by sex, age, the location of the tumor, the degree of fissure development, and the surgeon's preference.

Objective: To determine whether reducing the cetrorelix dose in the antagonist protocol to 0.125 mg had any deleterious effects on follicular development, the number and quality of retrieved oocytes, or the number of embryos, and to characterize its effects on the affordability of assisted reproductive technology. Methods: This randomized controlled study was conducted at the Fertility Unit of Tanta Educational Hospital of Tanta University, the Egyptian Consultants' Fertility Center, and the Qurrat Aien Fertility Center, from January 1 to June 30, 2017. Patients' demographic data, stimulation protocol, costs, pregnancy rate, and complications were recorded. Patients were randomly allocated into two groups: group I (n = 61) received 0.125 mg of cetrorelix (the study group), and group II (n = 62) received 0.25 mg of cetrorelix (the control group). Results: The demographic data were comparable regarding age, parity, duration of infertility, and body mass index. The dose of recombinant follicle-stimulating hormone units required was $2,350.43{\pm}150.76$ IU in group I and $2,366.25{\pm}140.34$ IU in group II, which was not a significant difference (p= 0.548). The duration of stimulation, number of retrieved oocytes, and number of developed embryos were not significantly different between the groups. The clinical and ongoing pregnancy rates likewise did not significantly differ. The cost of intracytoplasmic sperm injection per cycle was significantly lower in group I than in group II (US $ $494.66{\pm}4.079$ vs. US $ $649.677{\pm}43.637$). Conclusion: Reduction of the cetrorelix dose in the antagonist protocol was not associated with any significant difference either in the number of oocytes retrieved or in the pregnancy rate. Moreover, it was more economically feasible for patients in a low-resource country.
