A notable secular trend in early puberty onset has been described over the past few decades. Also, the prevalence and incidence of precocious puberty is increasing not only in Korea, but also around the world. The manifestation of secondary sex characteristics before 8 years in girls and 9 years in boys is defined as precious puberty. The causes of precocious puberty can be classified as gonadotropin releasing hormone (GnRH)-dependent, also known as central precocious puberty (CPP), or GnRH-independent. Evaluation of patient with precocity requires detailed examination of the clinical manifestation, GnRH stimulation test, and imaging of the central nervous system if indicated. The standard treatment for CPP is GnRH agonist, which is beneficial for adequate pubertal development and preservation of final adult height. In this paper, we investigate the diagnosis and adequate treatment of CPP.

PURPOSE: Salvage operation is performed to improve the functional deficit of vascular access. This study is planned to evaluate the utility of the hybrid surgery through a comparative analysis between the results of surgical thrombectomy and those of hybrid surgery, combining surgical methods and endovascular treatments. METHODS: From January 2007 to December 2008, surgical thrombectomy had been done to 55 patients, whereas hybrid surgery had been done to 111 patients from January 2009 to December 2011. We have done a comparative analysis on the patency rate after the salvage operation for each group, retrospectively. Medical records were reviewed for patient information and radiographic data was used for checking the stenosis site in the hybrid surgery group. RESULTS: There were no statistically significant differences between the two groups, including age, gender, diabetes status, hypertension, and vascular access site or type. The primary patency rate was significantly higher in arteriovenous fistulas (65%) compared with arteriovenous grafts group (55%), at 12 months (P<0.01). At one year after the salvage operation, the secondary patency rate was higher in the hybrid surgery group compared to the surgical thrombectomy group (43.8% vs. 23.7%, P<0.01). CONCLUSION: This study shows that hybrid surgery combining surgical methods and endovascular treatments can be more useful for the salvaging of thrombosed vascular access than performing only surgical thrombectomy.

BACKGROUND: Rosacea treatments including oral/topical medications and laser therapy are numerous but unsatisfactory. OBJECTIVE: To compare the effectiveness of the dual wavelength long-pulsed 755-nm alexandrite/1,064-nm neodymium: yttrium-aluminum-garnet laser (LPAN) with that of 585-nm pulsed dye laser (PDL) for rosacea. METHODS: This was a randomized, single-blinded, comparative study. Full face received four consecutive monthly treatments with LPAN or PDL, followed-up for 6 months after the last treatment. Erythema index was measured by spectrophotometer, and digital photographs were evaluated by consultant dermatologists for physician's global assessment. Subjective satisfaction surveys and adverse effects were recorded. RESULTS: Forty-nine subjects with rosacea enrolled and 12 dropped out. There were no significant differences between LPAN and PDL in the mean reduction of the erythema index (p=0.812; 3.6% vs. 2.8%), improvement of physician's global assessment (p=1.000; 88.9% vs. 89.5%), and subject-rated treatment satisfaction (p=0.842; 77.8% vs. 84.2%). PDL showed more adverse effects including vesicles than LPAN (p=0.046; 26.3% vs. 0.0%). No other serious or permanent adverse events were observed in both treatments. CONCLUSION: Both LPAN and PDL may be effective and safe treatments for rosacea.

BACKGROUND: Nevus of Ota (NO) is a relatively common pigmentary disorder in Asians. Tanino's classification is an old but tacit consensus to delineate the disease. Various treatment options have been presented. However, a few studies have been conducted on available laser options and current treatment strategies or the classification of NO. OBJECTIVE: To investigate current laser options and their effectiveness for the treatment of NO, contributing factors to clinical outcomes, and verification of classification. METHODS: A retrospective study of NO was conducted by reviewing medical charts and photographs of sixty-seven patients. Statistical analysis was used to compare excellent and poor outcomes and determine contributing factors. RESULTS: The median age of onset was below the age of 1 (interquartile range [IQR], 0~1). Tanino's and PUMCH classification systems failed to classify patients in 24 (35.8%) and 6 (9.0%) of patients, respectively. A 1,064 nm Q-switched Nd:YAG laser without additional lasers was used most frequently in 42 patients (62.7%). The frequency of treatment was 19.0 (IQR, 10.0~23.0) in the cured group defined as subjects showing 95% improvement or above, compared to 10.0 (IQR, 6.25~13.75) in the unattained group defined as subjects showing less than 95% improvement (p=0.001). CONCLUSION: A 1,064 nm Q-switched Nd:YAG laser is a reliable treatment armamentarium, functioning as a single infallible modality as well as a combination treatment modality for NO. Repetitive laser treatments without interruption seems to be the most suitable in clearing NO. The current classification systems of NO are defective. Thus, a new classification should be developed.
