PURPOSE: This descriptive study investigated the effects of authentic leadership and coworker support on psychological well-being of staff nurses. METHODS: The participants were 166 staff nurse working in university hospital located in D city. Data were collected from July 1 2017 to 31, 2017. Data analysis was performed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and hierarchical regression. RESULTS: The regression model that included demographics and coworker support explained about 40.0% of psychological well-being. Marital status, nurse satisfaction, turnover experience, and coworker support were the predictors of psychological well-being in staff nurses. CONCLUSION: Coworker support was an important predictor of the psychological well-being of staff nurse. Therefore, strategics to improve coworker support are needed to increase psychological well-being in the clinical field.

The objectives of this study were to observe normal peristalsis and mixing (or segmental movements) and to evaluate an acupuncture stimulation (ST-36 and BL-27) on the intestinal (duodenum) motility in normal dogs using duplex Doppler sonography. Fifteen healthy Beagle dogs were used for this experiment after the administration of warm saline and pellet feeding. The duodenal motility was examined using duplex Doppler sonography. Six hours after the pellet feeding, an electroacupuncture stimulation at ST-36 and BL-27 was applied and the duodenal motility was examined using duplex Doppler sonography pre-stimulation, during the stimulation and post-stimulation. After saline and pellet administration, the duplex Doppler sonograms showed 3 types of peristalsis and a mixing type (or segmental movement) of duodenum motility. In the peristalsis types, most yielded high-amplitude signals which had one high peak (type-1), two high peaks (type-2), and three high peaks (type-3) and lasted more than 1.3 seconds. Mixing type of duodenum motility had weak signals and were lasted more than 1.5 seconds. Among the peristalsis types, the type 1 and type 2 were predominant and the type 3 was rarely observed. The frequency of intestinal motility stimulated by ST-36 acupoint was increased during the acupuncture stimulation (20% increase compared to the basal value) and decreased (7% decrease compared to the basal value) after stimulation. The frequency of intestinal motility stimulated by BL-27 acupoint was decreased during the acupuncture stimulation (31% decrease compared to the basal value) and increased (18% increase compared to the basal value) after stimulation. There was a significant increase(p<0.01) between the value found in during and the post-stimulation tests. We conclude that duplex Doppler studies permit a graphic visualization of intestinal movements which can be qualitatively and quantitatively analyzed using this technique, it is possible to evaluate the gastrointestinal motility after an acupuncture stimulation.

Transcranial Doppler (TCD) was carried out to determine the resistive index (RI) values of normal canine cerebral arteries and its reproducibility and to evaluate the change of cerebral vascular resistance following diuretics administration. RI values of rostral cerebral artery (RCA) were compared between fontanelle window and temporal window. Normal ranges and reproducibility of the RI values were examined in the rostal cerebral artery (RCA) and caudal cerebral artery (CCA). And after administration of diuretics, TCD-derived RI values were measured at RCA and CCA. Cerebral vascular RI values of RCA and CCA were 0.55 +/- 0.05 and 0.55 +/- 0.03 in the normal dogs, respectively. There was no significant difference of RI between male and female; between fontanelle window and temporal window. Reproducibility of RI measurements between intraobserver and interobserver were relatively high. The RI of RCA and CCA were significantly increased 15 minutes after mannitol administration (p<0.01) and returned to baseline values by 30 minutes, but it did not significantly change after furosemide and saline administration. The results suggest that TCD is a useful test which can obtain reproducible results from any window and has the advantage of detecting subtle changes in cerebral vascular resistance.

BACKGROUND: Imiquimod is an immune response modifier that shows antiproliferative and antiviral characteristics through synthesis of multiple cytokines. Although it was originally approved by the Food and Drug Administration for the treatment of anogenital warts, it has also been successfully used to treat various skin conditions. OBJECTIVE: The aim of this study was to evaluate the current usage of 5% imiquimod cream for the treatment of various skin conditions in dermatologic clinics. METHODS: We reviewed the records of 270 patients with various skin conditions who were treated with 5% imiquimod cream. Data was collected through medical records, clinical photographs, and biopsy specimens. RESULTS: Besides anogenital warts, 5% imiquimod cream has been prescribed in more than 20 skin conditions. The most common skin disease was verruca vulgaris. Others, in order of prevalence, were molluscum contagiosum, actinic keratosis, condyloma accuminatum, and verruca plana. Among the 270 patients who were treated with 5% imiquimod cream, more than two-thirds showed clinical response, but only 26 patients (9.7%) achieved clinical complete remission with median clearing time of 7.3 weeks. While applying 5% imiquimod cream, 82 patients (30.4%) experienced local side effects that were generally mild and generally well-tolerated. The most common side effect was erythema and the others, in order of prevalence, were oozing, itching sensation, burning sensation, scabbing, erosion and pain. No systemic side effects were found. CONCLUSION: Although 5% imiquimod cream is licensed in Korea only for treatment of adult anogenital warts, other skin diseases such as verruca vulgaris are more commonly the treatment target in dermatologic clinics. As the reported therapeutic effects are various, more clinical studies are required to assess the safety and efficacy of imiquimod for the treatment of various skin conditions.

The height, width, and cross-sectional area of the vertebral canal and spinal cord along with the area ratio of spinal cord to vertebral canal in the cervical vertebra were evaluated in images obtained using computed tomography (CT). Measurements were taken at the cranial, middle, and caudal point of each cervical vertebra in eight clinically normal small breed dogs (two shih tzu, two miniature schnauzers, and four mixed breed), 10 beagles, and four German shepherds. CT myelography facilitated the delineation of the epidural space, subarachnoid space, and spinal cord except at the caudal portion of the 7th cervical vertebra. The spinal cord had a tendency to have a clear ventral border in the middle portion of the vertebral canal and lateral borders near both end plates. The height, width, and area of the vertebral canal and spinal cord in the cervical vertebra were increased as the size of dog increased. However, the ratio of the spinal cord area to vertebral canal area in the small dogs was higher than that of the larger dogs. Results of the present study could provide basic and quantitative information for CT evaluation of pathologic lesions in the cervical vertebra and spinal cord.

Percutaneous needle aspiration biopsy is a reliable and useful procedure for diagnosing tumor with a low rate of complications and high diagnostic reliability. Subcutaneous malignant seeding of the needle tract is a well-known complication of percutaneous needle aspiration biopsy. Implantation metastases of the abdominal and chest walls have been reported after puncturing the tumor lesions of the liver, kidney, adrenal gland, lung and pleura. We report here on a case of subcutaneous seeding of hepatoid thymic carcinoma on the right upper back after a percutaneous needle aspiration biopsy.

The second-generation oral anticancer agent UFT is a combination of uracil, which has fluorouracil's (5-FU) degradation-inhibitory effect, and tegafur, which is slowly converted to 5-FU in vivo, and UFT shows a higher 5-FU concentration in the tumor tissues than is achieved by tegafur alone or with comparable doses of intravenous 5-FU. Mucocutaneous side reactions induced by UFT are rare and these include photosensitivity of the lichenoid and eczematous types, acral erythema, hyperpigmentation, palmoplantar keratoderma and scleroderma-like reactions, and discoid lupus erythematosus (DLE)-like eruption. However, there has been no report in the Korean medical literature on patients presenting with a DLE-like eruption associated with UFT. So, we report here a case of DLE-like eruption induced by oral UFT.
