BACKGROUND: There are two kinds of mechanism for laser therapy according to selectie photothermolysis. Selective photothermolysis means that a chromophore can be selectively dei, stroyed with a laser of n appropriate wavelength and of a short pulse duration that is shortor than the thermal relaxation time of the chromophore. It is supposed that the side effects of the continuous wave laser, in which selective photothermolysis does not exist occur more often than when a pulsed wave laser is used. OBJECTIVE: We compar.d the side effects of flashlamp-pumped pulsed tunable dye laser(SPTL), whose treatment is baseal on selective photothermolysis, with those of copper vapor laser(CVL , which is a quasi-continuous thermal laser. METHODS: The laser cl arts of 498 patients with SPTL treatment and 485 patients with CVL, treatment in Asan Medical Center from 1989 to 1994 were examined, retrospectively. RESULTS: 1) Among 498 patients, with SPTL treatment, we observed various side effects in 47(9.4%). The incidences of individial side effects are as follows, hyperpigmentation in 6.2%(31), vesicl formation in 1.6% (8), surface texture change in 0.8% (4), Hypopigmentation in 0.6% (3), scar format,ion in 0.2% (1). 2) After CVL treatment, side effects occurred in 30(6.2%) among 485 patient.. Hyperpigmentation in 3.1%(15), vesicle formation in 2.5%(12), surface texture change in 0.2%(1), hypopigmentation in 0.2%(1), and scar formation in 0.1%(1) were observed. CONCLUSION: The total incidence of side effect.s after CVL treatment is not statistically different, from that after SPTL treatment, which contradicts the previous theory.

PURPOSE: A lateral thoracodorsal fasciocutaneous flap (LTFF) is a local fasciocutaneous flap that has been used in breast reconstructions since the 1980s. Although the LTFF is a wellstudied reconstruction procedure after radical surgery in Western countries, there is no report in Korea. By introducing the LTFF procedure, we suggest an easy reconstruction technique that can be performed by the breast surgeon directly. METHODS: Patients with lateral breast cancer and redundant lateral thoracic region might be candidates for this procedure. The flap consists of the lateral and dorsal extensions of the inframammarian fold as well as an extended line from the anterior axillary line. A quadrantectomy is performed through a planned skin incision, and an axillary lymph node dissection can be performed simultaneously if the sentinel lymph node is positive. The skin and subcutaneous fat with the fascia of the serratus anterior and latissimus dorsi muscle should be dissected carefully. A wedge-shaped flap can be acquired successfully. The lateral breast defect is then reconstructed by a rotation of the flap. The axis of the flap is drawn following the inframammarian fold so that the final scar would be under the brassiere line. RESULTS: Nineteen patients were treated with the LTFF after breast conserving surgery. All tumors were located in lateral breast regions. Seroma occurred in three and partial fat necrosis and partial flap necrosis were observed in each one. The cosmetic result based on four-point scoring system of breast cosmesis showed excellent in seventeen and good in two. CONCLUSION: Despite its long scar line, with appropriate patient selection, a LTFF might be a useful method for breast reconstructions.

Human is infected by third stage filariform larvae of Strongyloides stercoralis which is a soil-transmitted nematode. Rhabditiform larvae passed in feces can transform into infectious filariform larvae either directly or after a free living phase of development. Most infected patients may be asymptomatic or have mild cutaneous symptoms or induces non-specific complaints such as moderate abdominal pain, nausea and diarrhea. However, in immunocompromised hosts, the parasite is augmented by autoinfection, resulting in hyperinfection and can disseminate widely and can be fatal. We report a case of strongyloidiasis associated with intestinal obstruction in a patient with alcoholic liver disease.

The incidence of tuberculosis (TB) had gradually been declining all over the world, but in recent years, TB has been increasing due to the spread of the human immunodeficiency virus (HIV). When immune-suppression status deteriorates further, extrapulmonary TB generally appears more often. Abdominal TB is one type of extra-pulmonary TB, which may involve the gastrointestinal tract, peritoneum, lymph nodes or solid viscera. We encountered a case who had initially been diagnosed as having abdominal TB, had progressed to acute respiratory distress syndrome and was eventually confirmed as having developed acquired immune deficiency syndrome. In cases of coinfection of TB and HIV, it is reported that immunological responses become poor and complications with higher morbidity frequently occur. Therefore, the Korean guidelines for TB should be revised to ensure whether HIV infection exists in TB patients.

PURPOSE: This study aimed to identify changes in smart device usage trends of young children using two studies conducted in 2015-2016 and 2017 respectively. METHODS: We compared the data of the previous study of 130 children (Group A) and the new study of 162 children (Group B). The children and parents were recruited from kindergartens in Seoul and Guri/Namyangju cities. We used the “Parental questionnaire for smart device usage status.” RESULTS: There were some changes in the smart device usage in young children and parental perception. In the 2017 study, smart device usage time increased during weekends (P < 0.05) and the usage with siblings decreased (P < 0.05). In 2017, the smart device was mostly used when children had to be quiet without disturbing others (36.8%). No significant difference existed in the main purpose of use: watching video clips (79.3% vs 76.6%). Overall control of the usage was still largely exercised by mothers; however, when using applications, mothers still only helped the children on request (51.8% vs 49.7%). Regarding the effect of smart device on children, responses of “not knowing” decreased and “will be negative” and “will be positive” increased (P < 0.05). Additionally, most mothers thought that “Although the smart device is currently unnecessary, it will be needed in future” in 2017 (46.3%). CONCLUSION: Limiting the smart device usage time during the weekends and increasing parental involvements are recommended. Guidelines for smart devices usage in young children are also necessary considering the changes in parental attitudes in recognizing the smart device usage as unavoidable.

Journal of the Korean Child Neurology Society 2018;26(3):135-145
PURPOSE: To investigate the relationship between the smart devices usage-related factors and self-regulation ability development in early childhood. METHODS: Parental questionnaires of 187 children aged 3–6 years were analyzed. The metrics included smart device usage frequency (times/week, scored as uFreq), smart device usage time (hours/day, scored as uTime), parental scale for appropriate smart device usage level (scored as uLevel), the Korean-developmental screening test (K-DST), and the scale for self-regulation ability in young children (scored as SRS, and including four sub-categories: self-appraisal, self-determination, behavior inhibition, and emotionality). The correlations were analyzed by total age group and by each age. RESULTS: In the total age group analysis, uFreq and uTime were negatively correlated with mean SRS (rs =−0.366, −0.330; P < 0.001) and sub-category SRS (rs =−0.186 to −0.370; P < 0.05). Mean uLevel score was positively correlated with mean SRS (rs =0.406; P < 0.001) and most of the mean sub-category SRS (rs =0.174 to 0.362; P < 0.05). In 3-year-old children, the mean SRS was strongly negatively correlated with uFreq (rs =−0.751; P < 0.001), negatively correlated with uTime (rs =−0.518; P < 0.001), and positively correlated with mean uLevel score (rs =0.533; P=0.013). Such correlations seemed to decrease at the age of 4–6 years. CONCLUSION: Self-regulation ability was significantly correlated with smart device-related factors and was the highest in the 3-year-old children. Encouraging appropriate smart device usage will be helpful for self-regulation development of young children.

Journal of Asthma, Allergy and Clinical Immunology 1998;18(4):647-655
BACKGROUND: Many young children suffer from wheezing illness during viral respiratory infection, and some of them experience wheezing many years later and ultimately develop bronchial asthma. It is not clear whether atopy or bronchial hyperresponsiveness in the family is a significant risk factor for asthma in this clinical setting. Objective : To examine the genetic basis for the development of asthma after early childhood wheezing. Materials and METHODS: A measurement of serum total IgE concentration, skin prick test to common inhalant allergens, and methacholine bronchial provocation test were performed in 29 asthmatic children and their parents, and 22 non-asthmatic children with the past history of wheezing illness during the first three years of age and their parents. A questionnaire was performed to assess the presence of asthma and allergic rhinitis in the parents. RESULTS: Positive skin test response to common inhalant allergens was more prevalent in asthmatics than in non-asthmatics(67.8% vs. 27.2%). Serum total IgE concentration was significantly higher in asthmatics than in non-asthmatics(geometric mean: 173 vs. 83 IU/ ml). Positive skin test response to comman inhalant allergens was more prevalent in parents of asthmatics than in thoae of non-asthmatics(51.7% vs. 25.0%), but serum total IgE level was not different between the two groups(geometric mean: 132 vs. 120 IU/ml). Positive rate of methacholine bronchial provocation test, geometric mean of PC20-methacholine, and BR index were not different between the parents of asthmatics and non-asthmatics (18.1% vs. 13.9%; 164 vs. 180 mg/ml; 1.154+-0.077 vs. 1.055+-0.068, respectively). CONCLUSION: It is suggested that personal atopy is important in the development of asthma after early childhood wheezing, and parental atopy rather than bronchial hyperresponsiveness is a risk factor for the development of childhood asthma in this clinical setting.
