Objective:
This study aimed to validate the reliability and validity of the Diagnostic Interview for the Internet Addiction Scale (DIA) among Korean children and adolescents in the clinical setting.
Methods:
We collected the clinical data from university hospitals in South Korea and 194 children and adolescents (aged 7–18 years) completed the questionnaire. The content validity was conducted on 10 items of the DIA and an internal consistency test was performed for the verification of reliability.
Results:
Participants on average, aged 13.17 years (standard deviation=2.46), and 75.3% (n=146) were boys. The DIA was highly correlated with the scores of the Korean scale for Internet addiction for adolescents, Young’s Internet Addiction Test, Internet addiction proneness scale for children and adolescents. The overall sampling suitability of the 10-item scale was tested using the Kaiser–Meyer–Olkin, resulting in a high value of 0.861. The DIA revealed a two-factor structure and the Cronbach’s alpha correlation coefficient for the total scale was 0.806. Confirmatory factor analysis showed an acceptable model fit (root-mean square error of approximation=0.058, comparative fit index=0.950, and Tucker-Lewis Index=0.919).
Conclusion
The DIA may suggest in-depth-scale examinations of the factors that influence Internet addiction. We may expect that DIA would be used efficiently for the diagnosing of Internet addiction and further studies for the assessment.

Basal cell carcinoma (BCC) is one of the most commonly diagnosed malignant skin tumors and develops characteristically on sun-exposed areas, such as the head and neck. Ultraviolet light exposure is an important etiologic factor in BCCs, and BCCs arising from non-sun- exposed areas are, therefore, very rare. In particular, the axilla, nipple, the genital and perianal areas are not likely to be exposed to ultraviolet light; thus, if BCC develops in these areas, other predisposing factors should be considered. Herein, we report a case of BCC arising on the pubic area in a 70-year-old man. We also performed a survey of the literature and discussed the 19 cases of BCC from non-sun-exposed areas reported to date in Korea.

Immobilization of skin grafts on the recipient bed is essential for graft survival. There are several methods of securing skin grafts to the recipient wound bed. Classically, nylon basting sutures and a tie-over bolster dressing are commonly used. This method is currently recognized to ensure that the full thickness skin grafts "take"; however, this method is complicated and time-consuming. Moreover, suturing in this manner may also pull the edges of the skin with too much tension, cause elevation and crater-like deformity and suture marks. We experienced two cases of sutureless Burow's graft using skin tapes to reconstruct a skin defect after Moh's micrographic surgery. Instead of the conventional method, the Steri-strip(R) was used to fix the graft and a light compressive dressing with dry gauze and Tegaderm(R) was applied over the graft. This method has the advantage of being convenient to apply and remove, time-saving and inexpensive. Therefore, we recommend the use of the sutureless method using skin tape as an alternative to suturing small skin grafts, and particularly for the relatively immobile areas on the face.

BACKGROUND: Nalbuphine is one of the opioid agonist-antagonists and is used frequently in the anesthetic field. Usage is focused on potent analgesic action and the adjuvant of narcotics because of less complications with preserved analgesia. The most common routes of administration for postoperative pain control are epidural and intravenous, so we compared both pharmacokinetic profiles. METHODS: Twelve patients were randomly divided into two groups. All patients were given a spinal anesthesia with tetracaine hydrochloride. One group (n = 6) received nalbuphine 10 mg via epidural route and another group (n = 6) received the same dose via intravenous route. Venous blood was drawn at 0, 0.25, 0.5, 1, 2, 4, 6 and 8 hours to measure plasma nalbuphine concentrations. Analysis was performed by high performance liquid chromatography with an electrochemical detector. RESULTS: At 0.25 hour, the plasma concentration of nalbuphine was significantly higher in the epidural administration group (49.48 +/- 4.98 ng/ml) than in the intravenous administration group (40.44 +/- 1.64 ng/ml). At 6 and 8 hours, the plasma concentration of nalbuphine was significantly higher in the epidural administration group (5.98 +/- 1.86 ng/ml, 3.85 +/- 0.94 ng/ml) than in the intravenous administration group (3.80 +/- 0.33 ng/ml, 2.43 +/- 0.32 ng/ml). Clearance, elimination half life, volume of distribution and AUC were not significantly different between the two groups. CONCLUSIONS: The plasma concentrations of nalbuphine via epidural route and intravenous route were similar in both groups after 0.25 hour to 6 hours. At 0.25 hour and after 6 hours, the epidural administration group had a higher plasma concentration of nalbuphine than the intravenous administration group.

Halo nevus is a pigmented nevus surrounded by a round or oval depigmentation. Of patients with halo nevus, 18 to 26% patients have vitiligo, either involving the nevus or at a distant site. While the exact etiology of halo formation and vitiligo is unknown, several theories suggest that common immunologic mechanisms are involved in the destruction of melanocytes of both phenomena. Unlike common melanocytic nevus, congenital nevus associated with both halo formation and concurrent extralesional vitiligo is very uncommon and only one case has been reported in the Korean dermatological literature. A 19-year-old female presented with surrounding depigmentation around a congenital hairy nevus on the left forearm. Simultaneously, vitiligo appeared on the lowerabdomen and surrounding regions of both areola. The halo depigmented lesion around congenital nevus and the periareolar vitiliginous lesion shared some histological and immunohistochemical features. These findings further support common immunological mechanisms of pigment destruction in both phenomena.

BACKGROUND: There are various methods of reconstruction of cutaneous surgical defect after removal of skin tumor, and skin graft is frequently used. Classically, in full-thickness skin graft (FTSG), nylon basting sutures with a tie-over bolster dressing are used in securing skin graft to the recipient wound bed, but this method is complicated, time-consuming, and may cause complications. OBJECTIVE: The aim of this study was to evaluate the usefulness of an adhesive skin tape (Steri-strip(R)) for securing a graft without suture when performing a Burow's skin graft, one of the types of FTSG. METHODS: We conducted a case-controlled retrospective study. A total of 45 patients (total 46 cases) treated with Burow's skin graft after removal of skin tumor between May 2006 and August 2010 were enrolled in this study, and grafts were secured with Steri-strip(R) (case, n=26) or conventional tie-over bolster dressings (control, n=20). The cosmetic results were scored at 1, 3, and 6 months after the operation. Also, the size and depth of the defect were measured and the run-time of the operation for the skin graft was checked. RESULTS: The operation time for the Steri-strip(R) group was significantly less than for the conventional tie-over bolster dressing group (p<0.001). No significant differences were observed between the groups with regards to age, sex, location, size, depth of the defect, prevalence of complications, and scored cosmetic results at 6 months after operation (p>0.05). CONCLUSION: Sutureless Burow's graft with skin tape required less time than the conventional method with a similar cosmetic result. Thus we suggest that sutureless Burow's graft with skin tape may be an easy and useful method to reconstruct the defect after skin surgery.
