Seborrheic keratosis is one of the most common benign epithelial tumors, especially in elderly patients. Squamous cell carcinoma is the second most common malignant tumor of the skin. Despite the fact that both tumors are common, malignant transformation of seborrheic keratosis rarely occurs. Herein we report a case of squamous cell carcinoma arising in a patient with pre-existing seborrheic keratosis.

BACKGROUND AND PURPOSE: The "closing-in" phenomenon refers to the tendency to copy near or overlap a model while performing figure-copying tasks. The mechanisms underlying the closing-in phenomenon have not been fully elucidated, and previous studies only investigated the mechanisms through neuropsychological tests. We investigated the neuroanatomical correlates of the closing-in phenomenon using voxel-based morphometry (VBM). METHODS: Thirty-eight patients diagnosed with probable Alzheimer's disease (AD) and 21 normal controls were included. All subjects underwent neuropsychological testing to diagnose dementia and magnetization prepared rapid acquisition gradient echo brain magnetic resonance imaging for the voxel-based statistical analysis. The subjects were asked to copy the modified Luria's alternating squares and triangles to quantify the closing-in phenomenon. We applied SPM8 for the VBM analysis to detect gray matter loss associated with the closing-in phenomenon. RESULTS: The patients with probable AD showed a higher closing-in score than that of the normal control subjects (p<0.0001). The VBM analysis revealed more parietal and temporal atrophy in the patients with AD than that in the normal control group. Moreover, atrophy of the orbito-frontal area was associated with the closing-in phenomenon. CONCLUSIONS: The closing-in phenomenon is dysfunction while performing figure-copying tasks and is more common in patients with AD. The analysis of the orbito-frontal area, which is associated with inhibiting primitive reflexes, revealed that the closing-in phenomenon is an imitation behavior commonly observed in patients with frontal lobe damage.

Multiple congenital melanocytic nevi (MCMN), defined as the distribution of more than three small- or medium- sized congenital melanocytic nevi (CMN) on the body without a giant CMN, is a rare disease comprising about 4% of patients with CMN. Because MCMN accompanies neurodevelopmental delay, including seizures in 25% of patients as well as the risk of malignant melanoma, it must be carefully followed-up. We report a case of MCMN with developmental delay in a 19-month-old Korean boy. He had a history of febrile seizure when he was 18 months old. He showed a speech delay after the 1-year-follow up, even though there was no evidence of neurocutaneous melanosis (NCM) on brain magnetic resonance imaging (MRI) at the first visit. As MRI has a low sensitivity for detecting NCM in patients with MCMN older than 4-months, close neurodevelopmental assessments should be considered to provide a chance for early rehabilitation.

Purpose: Spinal surgeries are often associated with a high incidence of perioperative blood loss, which poses several complications. Much current research focuses on the importance of antifibrinolytic drugs during spinal surgeries to reduce blood loss, which can also reduce the risk of the need for blood transfusions. We evaluated the effects of prophylactic, low-dose tranexamic acid (TXA) in spinal fusion surgeries on blood loss, blood transfusions, and associated complications. Materials and Methods: TXA was administered to 90 patients at a constant infusion rate of 10 mg/kg for 20 minutes after anesthesia induction, followed by a maintenance dose of 1 mg/kg/h until the end of the operation. An additional 91 patients were included as controls. Results: There were no significant differences between the study groups in terms of intraoperative blood loss, which was 500 mL for both groups (p>0.999). Also, intraoperative blood transfusion requirements were similar between both groups (p=0.330). Mean blood transfusion amounts were 125±35 mL for patients in the TXA group and 85±25 mL in the control group. However, there was a significant reduction in postoperative blood transfusion (p=0.003) in the TXA group. Only three cases in the TXA group required blood transfusion, while 15 cases in the control group did. Conclusion We confirmed that low dose TXA has no effect on intraoperative blood loss volume or blood transfusion requirements and that it can significantly reduce the need for postoperative blood transfusions.

Soft fibromas are benign skin lesions that primarily occur in the neck, axillae, and groin locations. The occurrence of soft fibroma lesions in the nipple is extremely rare. Herein, we present two cases of soft fibroma of the nipple, which occurred in a 51-year-old woman (Case 1) and a 32-year-old woman (Case 2). The mammographic and ultrasonographic features of each case are described in this report. Mammography revealed an oval-shaped isodense mass in Case 1 and an irregular-shaped isodense mass in Case 2. On ultrasonography, Case 1 showed an oval-shaped hypoechoic mass with increased vascularity, whereas Case 2 presented a microlobulated, irregular-shaped, iso- to hypo-echoic mass with subtly increased vascularity at the stalk. In both cases, surgical excision was performed and pathological examination revealed soft fibroma.

Objective: To investigate the effects of anti-tumor necrosis factor (TNF) treatment on lipid profiles and identify risk factors for an increase in total cholesterol (TC) after the anti-TNF treatment in ankylosing spondylitis (AS) patients. Methods: This retrospective cohort study analyzed AS patients who received the first-line anti-TNF treatment. Patients with at least nine months of follow-up were included; those who were under 18 years or on any lipid-lowering agent were excluded. A linear mixed model was used to assess the impact of anti-TNF inhibitors on disease activity and lipid profile (TC, low-density lipoprotein [LDL], high-density lipoprotein [HDL], and triglycerides [TG]). Univariable and multivariable linear regression were used to identify risk factors for an increase in TC after 3 months of anti-TNF treatment. Results: A total of 315 AS patients were enrolled (78.1% male, median age 32.0 [26.0~41.0]). TC, HDL, and TG levels significantly increased particularly within the first 3 months of anti-TNF treatment, while LDL level did not show significant changes.Changes in inflammatory markers and lipid particles (TC, LDL, TG) were correlated over time, but HDL showed no significant correlation. Older age, higher baseline erythrocyte sedimentation rate, and lower baseline LDL level were related to an increase in TC after 3 months of the anti-TNF treatment. Conclusion In AS patients, anti-TNF treatment has been found to increase lipid particles, potentially due to its anti-inflammatory effects. Future research should explore the underlying mechanism and the clinical implications of dyslipidemia, particularly the occurrence of cardiovascular events, following anti-TNF treatment in AS patients.

BACKGROUND: This study examined the effects of the method of delivery of brief advice on the readiness to change in at-risk drinkers. METHODS: The participants were 103 at-risk male drinkers who visited Chungnam National University Hospital for general health examinations. Baseline data on drinking behavior, readiness to change drinking behavior, and sociodemographic characteristics were obtained from a questionnaire. Family physicians gave two minutes of advice by telephone or in-person. The brief advice comprised a simple statement that the patient's drinking exceeded the recommended limits and could lead to alcohol-related problems. It also included advice to moderate one's drinking. One month later, the readiness to change was assessed again by telephone. The improvement in the readiness to change according to each method of delivery was investigated. RESULTS: Initially, among the 58-patient in-person advice group, 12 patients were in the precontemplation stage, 38 in the contemplation stage, and 8 in the action stage. One month after the advice was given to the patients, the distribution had changed significantly (P < 0.001) to 1, 21, and 36 patients, respectively. Among the 45-patient telephone advice group, 7 patients were in the precontemplation stage, 32 patients were in the contemplation stage, and 6 patients were in the action stage before the advice. The distribution had changed significantly (P < 0.001) to 1, 17, and 27 patients, respectively, 1 month after the advice. CONCLUSION: These results suggest that brief advice by family physicians is effective in improving the readiness to change of at-risk drinkers, regardless of the delivery method.

BACKGROUND: Nefopam is a centrally acting, non-opioid analgesic drug used to reduce opioid consumption and so reduce the prevalence of postoperative nausea and vomiting (PONV). This study compared and assessed the effects of nefopam and ketorolac on postoperative pain and PONV after thyroid surgery. METHODS: Two hundred patients underwent total thyroidectomy with central compartment neck dissection in our hospital during a 5 month enrollment period. Group N and Group T was administered nefopam 20 mg and ketorolac 30 mg, respectively, during the last 30 minutes of surgery. Pain was measured using a 10-point numerical rating scale. Pain scores and PONV were assessed 30 min, 1, 6, and 24 h postoperatively. RESULTS: Pain scores and episodes of vomiting and shivering did not differ significantly between the two groups. Group N patients experienced fewer episodes of nausea at 30 min, 1 h and 6 h after the operation. CONCLUSIONS: Nefopam and ketorolac are similarly effective in reducing postoperative pain after thyroid surgery. Postoperative nausea was less in Group N patients within 6 h postoperatively, especially 1 h. Nefopam is favored for pain management after thyroidectomy.

Mycosis fungoides (MF) is the most frequent cutaneous T cell lymphoma (CTCL). Since the major tumor cell of MF is the helper T cell, positive markers are usually CD3, CD4 and CD45RO. Some MFs show CD30 positivity and the major differential diagnosis for MF with CD30 positivity includes transformed MF and MF concurrent with primary cutaneous anaplastic large cell lymphoma and lymphomatoid papulosis. As each disease shows a different prognosis, an exact diagnosis is crucial for proper treatment. We now report a case of 44-year-old male patient with mycosis fungoides which developed several papules on preexisting MF patches. On biopsy of the newly formed papules, CD 30 positive cells were observed and the histologic features were consistent with lymphomatoid papulosis. Both the lesions of lymphomatoid papulosis and MF responded well to narrow band ultraviolet B phototherapy.
