Background: Psoriasis is a chronic inflammatory autoimmune disease. Some studies have demonstrated a relationship of psoriasis with vitamin D (Vit D) deficiency or serum lipid levels. Objective: We aimed to compare serum levels of Vit D and lipids in patients with active psoriasis and control subjects. Additionally, we analyzed the relationship of disease severity with serum Vit D and lipid levels. Methods: A total of 243 patients were retrospectively analyzed. Statistical data were evaluated, and the values were considered significant at p＜0.05. Results: Statistically significant difference in Vit D levels between the psoriasis (n=117) and the control groups (n=126) was not found. In addition, an association between Vit D levels and the disease severity, using the psoriasis area and severity index (PASI) was not observed. The proportion of overweight patients (body mass index [BMI]≥ 23 kg/m2 ) was higher in the psoriasis group than in the control group, and there was a significant relationship between the increase in PASI and the serum triglycerides (TG) levels (p＜0.05). Conclusion The psoriasis and control groups did not show a statistical difference in serum Vit D levels. In the subgroup analysis of cases with normal BMI, excluding the underlying disease, no significant difference in Vit D levels between the two groups was observed. However, the association of psoriasis with factors, such as BMI and TG, was found to be significant; hence, these could be therapeutic targets in patients with psoriasis to improve their quality of life. Controlled and well-designed studies are required in the future.

Primary localized cutaneous amyloidosis (PLCA) is characterized by extracellular deposition of pathological fibril aggregation of proteins in the skin without systemic involvement.Macular amyloidosis, lichen (papular) amyloidosis, and nodular amyloidosis are three different subtypes of PLCA. Although the pathological mechanism of PLCA has not yet been clarified, it is assumed that a nucleus formation of amyloid fibril is formed due to repeated external stimulation, such as subcutaneous injection, which often poses diagnostic challenges. Herein, we present a 54-year-old Korean male patient with cutaneous localized amyloidosis which occurred after repeated local insulin injections, and discuss the relationship between insulin therapy in patients with diabetes mellitus and dermal amyloid deposition.

Radio-frequency ablation (RFA) is a curative treatment for hepatocellular carcinoma (HCC). Percutaneous RFA has been shown to be beneficial for patients with small renal cell carcinoma (RCC) lacking indications for resection. We experienced the case of a 53-year-old male who had conditions that suggested HCC, RCC, and alcoholic liver cirrhosis. Abdominal contrast-enhanced computed tomography (CT) and magnetic resonance image showed liver cirrhosis with 2.8 cm ill-defined mass in segment 2 of the liver and 1.9 cm hypervascular mass in the left kidney. These findings were compatible with the double primary cancers of HCC and RCC. Transarterial chemoembolization (TACE) was performed to treat the HCC. After the TACE, a focal lipiodol uptake defect was noticed on a follow up CT images and loco-regional treatment was recommended. Therefore, we performed RFAs to treat HCC and RCC. There was no evidence of recurrence in the follow up image after 1 month.

Fixed drug eruption (FDE) is a well-defined hyperpigmented patch that recurs in a fixed location each time a particular drug is taken. Common causative agents of FDE are nonsteroidal anti-inflammatory drugs, non-narcotic analgesics, sedatives, anticonvulsants, sulfonamides, and tetracycline. We report a 33-year-old male who presented with a recurrent, localized, brownish-to-erythematous macule and papules on the peri-philtrum area two hours after taking valacyclovir. Three episodes of valacyclovir ingestion for treatment of Herpes simplex virus infection provoked a similar skin rash at the same site. Histopathology results showed vacuolar degeneration in the basal layer of the epidermis, pigmentary incontinence, and perivascular inflammatory cell infiltration in the papillary dermis. Although patch test and skin prick test showed negative responses to acyclovir and valacyclovir, an intradermal test showed a positive reaction only to valacyclovir. The oral provocation test to acyclovir and valacyclovir showed a positive reaction only to valacyclovir. Through drug history, histopathological examination, patch test, intradermal test, and oral provocation test, we established a final diagnosis of FDE due to valacyclovir without cross-reactivity to acyclovir. To find alternative therapeutic drugs, we suggest diagnostic tests with not only the suspected drugs, but also other drugs in the same class.

BACKGROUND/AIMS: The purpose of this study was to estimate the prevalence of Barrett's esophagus (BE) and its association with reflux esophagitis (RE) and peptic ulcer disease detected by free charge endoscopy which was covered by the National Health Insurance at a secondary care hospital, and to compare the results of the biopsy of BE with that of cardiac intestinal metaplasia (CIM). METHODS: A total of 4,002 patients underwent endoscopy from March 2010 to December 2012. BE was diagnosed if there was histologically proven specialized intestinal metaplasia, and CIM was diagnosed if intestinal metaplasia was accompanied with chronic gastritis. RESULTS: Four hundred twenty four patients underwent endoscopic biopsy, and the prevalence of BE was 1.0% (42/4,002). The mean age and the proportion of males in BE were significantly higher than those of the rest of study population, and BE had slight tendency related to RE than the rest of study population. CIM was observed in 34 patients and BE and CIM showed similar results, regarding age, sex and association with RE. The mean length of endoscopic Barrett's mucosa of BE group was 9.2+/-5.1 mm, and it was similar to that of CIM. CONCLUSIONS: The prevalence of BE in the secondary care hospital was not low, and old age and male sex were significantly associated with BE. Because BE was observed in about 10% of biopsied patients and CIM was observed in a similar percentage with BE, the precise targeted biopsy is warranted and the biopsy method should be reestablished through the large prospective study of multiple secondary care hospitals.

BACKGROUND: Laryngoscopy and tracheal intubation are associated with hemodynamic pressor responses, which can have adverse effects. During anesthesia induction with propofol target-controlled infusion (TCI), we aimed to determine the most appropriate dosage of alfentanil required for intubation, using a steady effect-site concentration of propofol and with the use of vecuronium. METHODS: Eighty ASA class 1 or 2 patients presenting for elective surgery were allocated at random to one of four groups. Anesthesia was induced in all patients with TCI of propofol target concentration 8 microgram /ml, followed by vecuronium (0.12 mg/kg). This was reduced to 5microgram/ml when the effect-site concentration had been 4microgram/ml. After the effect-site concentrations had reached to 5microgram/ml, control group received normal saline, group 1 received alfentanil 10microgram/kg, group 2 received alfentanil 20microgram/kg, and group 3 received alfentanil 30microgram/kg. Laryngoscopy and intubation were performed 90 s later. Heart rate was monitored continuously. Systolic blood pressure, diastolic blood pressure and mean arterial pressure were measured at pre-induction, post-induction (pre-intubation) and post-intubation, respectively. Complications such as hypotention and bradycardia were recorded until 5 minutes had elapsed after tracheal intubation. RESULTS: Control group showed significant increases associated with tracheal intubation in all hemodynamic variables (P < 0.05). Post-intubation values decreased significantly from pre-induction values in groups 1, 2 and 3 (P < 0.05). In groups 2 and 3, hypotension and bradycardia occurred (zero in group 1) but there were no significant differences in their incidences between the three groups. CONCLUSIONS: We suggest that alfentanil 10microgram/kg constitutes the optimal dosage to obtund the hemodynamic responses to tracheal intubation, using propofol TCI (5microgram/ml) and vecuronium for induction of anesthesia.

BACKGROUND: Skin laser treatment has improved significantly and has become an effective treatment approach for many skin diseases while also having applications for beauty treatments. However, since skin laser transfers energy directly to the skin, the misuse of such treatment may result in permanent damage to skin tissues. OBJECTIVE: This survey of Korean adults, conducted to obtain their perspectives on and their treatment experience with skin laser treatment, will be used to determine the current status of skin laser treatment and to identify necessary changes to ensure proper and safe conduct of skin laser treatment. METHODS: From April 5th to April 12th, 2016, a survey was conducted to obtain information regarding the perspectives and the treatment experience of adults aged 20~59 years. RESULTS: Approximately 50% of the participants had experience with skin laser treatment, and among these, 24.7% had not received treatment at a dermatology clinic. Compared to treatment at a dermatology clinic, the danger of side effects was 1.7 times higher at a non-dermatology clinic, 2 times higher at a skin care shop, and 5.3 times higher at an Oriental medical clinic. Among patients who received skin laser treatment, 16.1% experienced side effects, and among these, 1 out of 4 patients visited a non-dermatologist for treatment of these side effects. CONCLUSION: The results of the survey showed that in order for the public to receive safe and effective skin laser treatment based on professional diagnosis, there is a definitive need to provide correct information to the public and to implement changes to ensure proper understanding of skin laser treatment among this population.
