OBJECTIVE: Public concerns and awareness of automated external defibrillators (AEDs) are essential for improving the survival outcomes of out-of-hospital cardiac arrest (OHCA) in the community. On the other hand, the proportion of OHCA, in which AED is used in a prehospital setting, is very low in Korea. The aim of this study was to identify the barriers and training issues of AEDs. METHODS: A nationwide population-based survey was conducted to analyze the current public trends in AED awareness, training, and intention to use in 2017 (n=506). The barriers and training issues of AEDs were then documented. For trend analysis, previous tri-temporal surveys were obtained in 2007, 2011, and 2015. RESULTS: Public awareness of AEDs has increased: from 5.8% in 2007, to 30.6% in 2011, 82.6% in 2015, and 79.4% in 2017 (P<0.001). The training experience of AEDs has increased over time: from 0.5% in 2007 to 8.2% in 2011 and 33.2% in 2017. Thirty-two percent of respondents knew how and where to find the AEDs, but only 12.5% were able to certainly locate their public-access AED near their residency or work places. The reasons for being unwilling to use the AED included not knowing how to use (65.0%), fear of causing harm to the victim (21.3%), and legal liability (11.7%). CONCLUSION: Not knowing the location of AED and how to use it, and being unaware of the Good Samaritan Law were the major barriers to public access defibrillation. Further research is urgently needed if AEDs are to be increased and more lives saved.

Labial adhesions are extremely rare in adolescent and adult populations, because the etiology of this entity commonly relates to chronic vulvar inflammation or irritation, and is basically associated with low estrogen status. Although a few cases reported urinary retention resulting from severe labial adhesions, there is no report of labial adhesion that precipitates upper genital tract infection in prepubertal and postpubertal females. We present a rare case of severe labial adhesion and consequential lower genital tract obstruction that allegedly causing bilateral pyosalpinx in a 14-year-old adolescent girl who decisively denied sexual experience. The patient was successfully treated with surgical lysis of adhesion and administration of antibiotics.

Background and Objectives: Blood pressure (BP) measurement using an auscultatory sphygmomanometer is recommended for diagnosing hypertension in children. As mercury sphygmomanometers (MSs) are banned owing to environmental concerns, it is crucial to determine the accuracy of mercury-free sphygmomanometers to replace them. We analyzed the accuracy of these devices to guide the National Survey selection. Methods: BP was measured thrice each with MS, auscultatory device (AD), and oscillometric device (OD) in 104 participants aged 10–18 using the National Survey data. The difference in BP was defined as the difference between MS and other devices. The BP differences, correlations, and influencing factors were analyzed. The frequencies of hypertension were also compared. Results: Systolic BP (SBP) and diastolic BP (DBP) differences between MS and AD were 0.88±3.36 mmHg and 0.63±3.95 mmHg, and those between MS and OD were 0.43±5.83 mmHg and 4.57±6.89 mmHg, respectively. The absolute error of <10 mmHg for DBP between MS and OD was 76%. The concordance correlation coefficient between MS and AD was 0.94 for SBP and 0.90 for DBP, and 0.81 and 0.67, respectively for MS and OD. Arm circumference negatively correlated with BP differences except for SBP between the MS and OD. The frequency of hypertension was not different between MS and AD but was underestimated by OD. Conclusions AD correlated well with MS, while OD did not, especially for DBP. The superiority of AD over OD suggests AD as a possible alternative for MS in the National Survey.

Removal of blunt esophageal foreign bodies using Foley catheter under a fluoroscopic guidance is a well-recognized procedure. However, since this procedure is rather cumbersome and uncomfortable to the patient, the authors tried to find an easier and more convenient modified technique. For 10 patients with esophageal foreign body, we tried the method to the patients who is lying in the right lateral decubitus position and 3 assistants hold head. arms, trunk and legs of the patients without tilting the table and without using immobilizer. Foley catheter is inserted through nostril, nasal cavity and pharynx to esophagus. In order to identify the Foley catheter in esophagus, 0.025 inch short wire was inserted in the Foley catheter. The balloon of a Foley catheter was inflated by 10cc of air, and the syringe was kept attached to the Foley catheter during the procedure. After passage of the foreign body through the upper esophageal sphincter, the balloon was deflated immediately and the foreign body was removed through the mouth. We successfully removed in removing all the blunt esophageal foreign body with ease. This modified method is also fast, safe and efficient.

We report a case of Dirty Neck in a 27-year-old male suffering from severe atopic dermatitis. 'Dirty Neck', a reticulate pigmentation of the anterior and anterolateral aspects of the neck, is a specific finding in some subjects with atopic dermatitis. Two groups have been indentified. One is found in older patients with severe atopic dermatitis whose pigmentary lesions develop after puberty and show little seasonal variation. The other is found in younger patients with mild eczema who have a increase in pigment during the summer. Our patient showed a dark brown colored, linear, reticulate pigmentation of the neck, especially anterolateral aspeet regarded as the former group. More comprehensive and detailed clinical study is needed to evaluate the importanee of this entity in regard to as a minor clinical feature of Korean atopic dermatitis.

Nucleic scids transfer the genetic information for serving a central biological purpose. The nucleic acids are polymers of nucleotides and they are mainly ribonucleic acid(RNA) and deoxyribonucleic acid(DNA). The nucleotides are stoichiometrically composed of five-carbon sugars, nitrogeneous bases, and phosphoric acids. The chemistry of nucleic acids and characteristics of different genomes are decribed for further study. Most of DNA genomes tend to be circular including bacterial genomes and eukaryotic mitochondrial DNA. Eukaryotic chromosomes in cells, in contrast, are generally linear. The ends of linear chromosomes are called telomeres. The genomes of different species, such as mammals, plants, invertebrates can be compared with the chromosome ends. The telomeric complex allows cells to distinguish the random DNA breaks and natural chromosomal ends. The very ends of chromosomes cannot be replicated by any ordinary mechanisms. The shortening of telomeric DNA templates in semiconservative replication is occurred with each cell division. The short telomere length is critically related to aging, tumors and dieases.

We report a rare case of primary glomerular disease with both features of IgA nephropathy and membranous glomerulonephritis in a 27 year-old woman with nephrotic syndrome. Histologically, glomeruli showed slight mesangial expansion, proliferation of mesangial cells, and short subepithelial spikes on capillary wall. Direct immunofluorescence demonstrated granular IgG and C3 deposits along the capillary walls, and IgA with C3 deposits in mesangium. Granular subepithelial and rnesangial deposits were observed by electron microscopy. The patient showed complete remission after 6 months therapy with steroid and ACE inhibitor.

Impetigo herpetiformis is a rare pustular eruption that may be seen in late pregnancy. It is associated with severe maternal and fetal complications in case of misdiagnosis and delayed treatment. The patient was a 25-years-old multigravida with psoriasis in her past history. At 20weeks gestation, she had been developed erythematous scaly annular patchs with papules and pustules on inner thigh. At 37weeks' gestation, the patient was suffered from a severely pruritic pustular rash with fever and leukocytosis. The skin of the affected areas was biopsied and showed intraepidermal pustular abscess with a neutrophilic infiltrate. Treatment commenced with intravenous fluids, antibiotics, systemic prednisone, steroid creams, and phototherapy(UVB) under the careful fetal well being monitoring. Cesarean section was done due to fetal distress, and a normal healthy male infant was delivered, following which the patient's condition improved rapidly.
