BACKGROUND: Epidermal grafting using cryotherapy for recipient sites is in widespread use. However the peripheral hypopigmented haloes that occur around the recipient sites require prolon gation of the treatment period. OBJECTIVE: We used a CO2 laser to remove the epidermis of the recipient sites for betteri results. METHODS: We treated lie localized vitiligo patients with CO2 laser to remove t.he epidermis and grafted suction blister rooves. We observed repigmentation and complications 1 month later. RESULTS & CONCLUSIONS : The superiority of this method is demonstrated by the fact 1) all prodedures can be completed on the day of operation 2) the incidence of hypertrophic scar and peripheral hypopigmented halos can be observed.The problems of this method are 1) uneven repigmentation of recipient. sites 2) hyperpigrnentation of recipient sites

Although gout often initially affects the peripheral joints, gout may also involve the axial joints. The radiologic changes of axial gout are more common than are clinically recognized. According to a recent report, when the spine CT images of peripheral gout were reviewed for features of axial gout, there was about a 14% frequency of suspected axial gout. The vertebral level and the finding with the most common spinal gouty changes were L4 and lumbar facet joint erosions. We describe here the case of a 36-year-old gout patient with low back and right buttock pain and his lesions were unexpectedly diagnostic of lumbar facet joint arthritis and right sacroiliitis.

A 15-year-old Schnauzer, showing right exophthalmos, was diagnosed as adenocarcinoma originated from the third eyelid gland. On computed tomography, a normal right third eyelid gland was not observed. Instead, a heterogeneous cystic mass invaded the retrobulbar space and displaced the eye globe dorsolaterally. In addition, lysis of the bony nasolacrimal duct was found, which was considered the tumor invasion. These findings indicated that third eyelid gland adenocarcinoma should be considered when a retrobulbar mass is found ventromedial to the globe without observation of the normal third eyelid and accompanies osteolysis of the bony nasolacrimal duct in dogs showing exophthalmos.

As the coronavirus disease 2019 (COVID-19) has rapidly spread worldwide, there are growing concerns about patients' mental health. We investigated psychological problems in COVID-19 patients assessed with self-reported questionnaires including the Patient Health Questionnaire-9, Generalized Anxiety Disorder-7 scale, and Impact of Event ScaleRevised Korean version. Ten patients who recovered from COVID-19 pneumonia without complications underwent self-reported questionnaires about 1 month after discharge. Of them, 10% reported depression and posttraumatic stress disorder (PTSD) while 50% had depression during the treatment. Perceived stigma and history of psychiatric treatment affected PTSD symptom severity, consistent with previous emerging infectious diseases. Survivors also reported that they were concerned about infecting others and being discriminated and that they chose to avoid others after discharge. Further support and strategy to minimize their psychosocial difficulties after discharge should be considered.

Background/Aims: Current evidence supports lung ultrasound as a point-ofcare alternative diagnostic tool for various respiratory diseases. We sought to determine the utility of lung ultrasound for early detection of pneumonia and for assessment of respiratory failure among patients with coronavirus disease 2019 (COVID-19). Methods: Six patients with confirmed COVID-19 by reverse transcription-polymerase chain reaction were enrolled. All had undergone chest X-ray and chest computed tomography (CT) on the day of admission and underwent multiple point-of-care lung ultrasound scans over the course of their hospitalization. Results: Lung ultrasound detected early abnormal findings of representative B-lines in a patient with a normal chest X-ray, corresponding to ground-glass opacities on the chest CT scan. The ultrasound findings improved as her clinical condition improved and her viral load decreased. In another minimally symptomatic patient without significant chest X-ray findings, the ultrasound showed B-lines, an early sign of pneumonia before abnormalities were detected on the chest CT scan. In two critically ill patients, ultrasound was performed to assess for evaluation of disease severity. In both patients, the clinicians conducted emergency rapid sequence intubation based on the ultrasound findings without awaiting the laboratory results and radiological reports. In two children, ultrasound was used to assess the improvement in their pneumonia, thus avoiding further imaging tests such as chest CT. Conclusions Lung ultrasound is feasible and useful as a rapid, sensitive, and affordable point-of-care screening tool to detect pneumonia and assess the severity of respiratory failure in patients hospitalized with COVID-19.

Aurora kinase A plays an essential role in mitosis including chromosome separation and cytokinesis. Aberrant expression and activity of Aurora kinase A is associated with numerous malignancies including colorectal cancer followed by poor prognosis. The aim of this study is to determine the inhibitory effects of LDD970, an indirubin derivative, on Aurora kinase A in HT29 colorectal cancer cells. In vitro kinase assay revealed that, LDD970 inhibited levels of activated Aurora kinase A (IC₅₀=0.37 mM). The inhibitory effects of LDD970 on Aurora kinase A, autophosphorylation and phosphorylation of histone H3 (Ser10), were confirmed by immunoblot analysis. Moreover, LDD970 inhibited migration of HT29 cells and upregulated apoptosis-related protein cleaved PARP. In cell viability assay, LDD970 was observed to suppress HT29 cell growth (GI₅₀=4.22 µM). Although further studies are required, results of the present study suggest that LDD970 provide a valuable insight into small molecule indirubin derivative for therapeutic potential in human colorectal cancer.

A 30 year-old female visited our out-patient clinic with painful joint swelling in both hands and feet. Because she had tested positive for rheumatoid factor, and her inflammatory markers were elevated, the case was initially classified as rheumatoid arthritis (RA), according to the 2010 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) classification criteria. However, radiographic examinations, including simple radiography and MRI, revealed that her peripheral bone lesions were compatible with bone tuberculosis. The patient also exhibited pulmonary tuberculosis (TB) on chest X-ray and CT examinations. She was treated with isoniazid (INH), rifampicin (RFP), ethambutol (EMB), and pyrazinamide (PZA), and exhibited a good response to these medications. The patient was diagnosed as having bone TB, and her peripheral bone lesions were resolved using anti-TB treatment. This was an uncommon case of bone TB mimicking RA.

BACKGROUND: This study aimed to evaluate the quality of surgical antibiotic prophylaxis (SAP) in a tertiary hospital. METHODS: Medical, anesthetic, and nursing records from the 27,320 procedures conducted in a tertiary hospital during 2012 were retrospectively reviewed. Three clinical performance indicators of SAP (selection of antibiotic, timing of the first administration, duration of prophylaxis) were included as part of the National Hospital Evaluation Program (NHEP) of the Health Insurance Review and Assessment Service. In addition, 2 other parameters were assessed according to recent guidelines (weight-based initial dosing for obesity, intraoperative re-dosing for excessive blood loss, and prolonged duration of procedures). RESULTS: Prophylactic antibiotics were administered in 19,637 (71.8%) of 27,320 total procedures. Quality of the 3 performance indicators was higher in the types of operations included in NHEP than in other procedures. However, additional doses were administered in 15 (1.2%) of 1,299 surgical procedures that lasted more than twice the half-life of the antibiotic used, and in 9 (3.3%) of 273 procedures with excessive blood loss greater than 1,500 mL. NHEP and non-NHEP results did not differ significantly. CONCLUSION: Three SAP quality indicators showed more improvement in NHEP surgical procedures than in non-NHEP, but the other parameters did not perform well regardless of NHEP assessment. Therefore, more measures to improve the appropriateness of SAP should be developed.

OBJECTIVES: To investigate the perception of and treatment pattern with regard to the four important issues in the management of lupus nephritis (LN), and to identify which parts of the LN treatment are difficult for physicians to carry out in clinical practice. METHODS: Four steps were carried out: pre-survey, LN symposium, post-survey, and meeting after the symposium.The two surveys were conducted with the same contents regarding renal biopsy, induction and maintenance treatment for class III and IV LN, and treatment for class V LN. The results of the first survey and the changes in opinion reflected in the second survey were comparatively analyzed. RESULTS: In the first survey, most of the respondent physicians replied that they would immediately conduct biopsy in the case of significant proteinuria. For the induction treatment of class III and IV LN, most of the respondent physicians selected high-dose cyclophosphamide. Mycophenolate mofetil and steroid combination therapy were selected for the maintenance treatment, and tacrolimus for the treatment of class V LN. There was a controversy in the drug selection, however, especially on the maintenance treatment of class III and IV LN and on the treatment of non-responsive class V LN. CONCLUSION: Some discrepancies were found in the treatment of LN in the real world. Although no recommendation was made for Korean LN patients in this study, the study results will help physicians select the most reasonable treatment for Korean LN patients based on experts' experiences and objective evidence.
