The objectives of this research are 1) to access different images held by three consumer groups (patients in university hospital, patients in corporation hospital, persons who are not currently visiting hospitals) on two types of hospitals(university hospitals and corporation hospitals), and 2) to investigate the personal factors affecting images of two types of hospitals. The data for this analysis were collected by questionnaire survey. A total of 403 interviews were conducted. Of these cases, 43 percent are male and 57 percent are female. The major statistical methods used for the analysis are paired t-test, factor analysis and multiple regression. The three consumer groups show a consensus that corporation hospitals are better than university hospitals in some aspects, such as kindness, facilities, and equipments. However, these groups disagree in certain images on two types of hospitals, such as popularity, credibility, and readiness for emergency. The images on two types of hospitals are varied by the respondents' sociodemographic characteristics such as age, sex, and by the type of hospital they are currently visiting.

Craniosysostosis syndrome is caused by premature fusion of bones of skull and face during fetal development. It is related to Fibroblast growth factor receptor gene and most common craniosynostosis syndromes are Apert, Pfeiffer and Crouzon. Apert syndrome is one of the severe type of craniosynostosis syndromes which shows mutations in the Fibroblast growth factor receptor 2 (FGFR2) gene. Pfeiffer syndrome is also related with FGFR 1 or 2 gene mutation. We experienced two patients with craniosynostosis syndromes, Apert syndrome and Pfeiffer syndrome. The first baby was a in-born female baby presented with syndactly of the hands and feet and facial dysmorphism including shallow orbit with deep crease above eye brow. Apert syndrome was confirmed by the presence of a mutation in FGFR2. The second patient visited our developmental delay clinic due to developmental delay at seven month old age. He showed facial dysmorphism including cloverleaf-shaped skull, micrognathia, low set ears, low nasal bridge and high-arched palate, but there were no syndactly or limb anomalies. He was suspected of Pfeiffer syndrome, however his FGFR2 gene study was normal. These patients need multidisciplinary team management and regular follow up for visual, auditory, and cognitive development functions Pediatricians have important role on recognizing the patients with facial dysmorphism, planning to evaluate accompanying anomalies and making appropriate decisions about the timing of surgical management to minimize growth and cognitive impairments.

Erosive pustular dermatosis of the scalp is a rare disorder of the elderly and it is characterized by pustular, erosive and crusted lesions of the scalp with progressive scarring alopecia. The predisposing factors have been reported to be trauma, including mechanical trauma, skin grafting, surgery and prolonged exposure of a bald scalp to UV light. Yet the laboratory data, the bacteriological and mycological investigations and the histopathologic findings of the previously reported cases were generally negative and not diagnostic. We herein present a case of erosive pustular dermatosis of the scalp that occurred after mechanical trauma on the previous skin graft site. This type of case has not been previously reported in the Korean dermatologic literature.

Oxygen therapy (OT) can relieve head pain in certain primary headache disorders, including cluster headache (CH). The exact underlying mechanism is currently uncertain, but suggested mechanisms include inhibition of the trigeminoautonomic reflex, modulation of neurotransmitters, and cerebral vasoconstriction. OT is the standard for acute treatment of CH, but patients with CH often experience considerable difficulties accessing home OT due to problems with insurance coverage. Inhalation of 100% oxygen at 6–12 L/min for 15–30 min using a non-rebreather face mask is one of the most effective acute therapies for CH, but several trials have indicated the superiority of higher oxygen flow rates of up to 15 L/min and/or using a demand-valve oxygen mask that can produce very high flow rates. Two randomized controlled trials have demonstrated the efficacy of OT in migraine, but obtaining reliable evidence is considered difficult because of different inhalation protocols, varying outcome measures, and small samples. There are some reports on the efficacy of OT as an adjuvant therapy in hypnic headache, primary headache in the emergency department, and even postdural puncture headache. The goal of this review article is to expand the knowledge regarding the use of oxygen in the treatment of headache disorders.

Background and Objectives:
Airway reconstruction surgery in children is still challenging, especially in cases of combined subglottic and posterior glottic stenosis (PGS). The aim of this study was to review the underlying reasons of failure in open airway reconstruction surgeries performed for children with combined subglottic and PGS.Subjects and Method We reviewed medical records of seven children who received more than two open airway reconstruction surgeries to finally achieve and maintain decannulation status for more than one year. Twenty-two reconstructive surgeries were performed and they consisted of 19 laryngotracheal reconstruction (LTR), 2 cricotracheal resection with end-toend anastomosis (CTR) and one extended CTR. For each patient, the following potential causes of failure were evaluated; preoperative evaluation (PE), type of reconstruction (TR), single vs. double staging (SDS), type of stent (TS), and perioperative optimization (PO).
Results:
The median age of patients at the time of surgery was 32 months (range, 4-64 months). Successful decannulation was achieved after the median open surgery of three (range, 2-5 times for each patient). Recognized causes of failure were as follows: 8 insufficient PE, 10 inadequate TR, 3 improper SDS, 8 ill-chosen TS, and 2 inappropriate PO.
Conclusion
PE of dynamic airway is important, especially vocal fold mobility and tracheomalacia. Types of reconstruction should be carefully decided after full consideration of potential causes of failure, and adequate laryngotracheal stent is essential.

OBJECTIVES: Length of in-hospital stay (LOS) is often regarded as a surrogate marker of efficiency in medical care. A shorter stay can redistribute medical resources to more patients if patient outcomes would not be worsened. However, the adequate LOS remains largely understudied for a complex head and neck cancer (HNC) surgery and free flap reconstruction. METHODS: Active management of LOS (14-day LOS program) included detailed preoperative surgical planning, intensive wound care, postoperative early ambulation and positive psychological encouragement. It was applied to 43 patients undergoing HNC surgery and free flap reconstruction. Outcomes such as noninferior oncological results, rates of timely adjuvant treatments and complications were compared with those of 125 patients without active management of LOS. In addition, the medical costs of shortened LOS were compared with those of the control group. Cases undergoing HNC surgery as a salvage treatment were excluded from both groups for analyses. RESULTS: Active management of LOS resulted in less in-hospital period compared to the control group (15.0 vs. 21.0 days, P=0.001), and reduced medical costs significantly. Incidence of postoperative complications was comparable between the two groups. Oncological outcomes did not differ significantly according to LOS. In all patients in both groups, initial high T status (T3–4) and occurrence of postoperative complications were independent risk factors for long LOS (>30 days). CONCLUSION: In patients undergoing HNC surgery with free flap reconstruction as an initial treatment, a 14-day LOS could be safe in terms of comparable oncological outcomes and postoperative complications. To achieve this goal safely, careful management for T3–4 tumors and prevention of postoperative complications seem to be necessary.

Clostridium difficile (C. difficile) is a common causative agent of pseudomembranous colitis (PMC). C. difficile-associated diarrhea (CDAD) ranges from mild diarrhea to life threatening PMC. Recently, a highly virulent strain of C. difficile polymerase chain reaction ribotype 027 was found in North America, Europe, and Japan. A 52-yr-old woman with anti-tuberculosis medication and neurogenic bladder due to traffic accident experienced five episodes of C. difficile PMC after taking antibiotics for pneumonia along with septic shock and acute renal failure. She was readmitted to the intensive care unit and treated with oral vancomycin with refractory of oral metronidazole, inotropics and probiotics for over 60 days. C. difficile isolated both at the first and the last admission was identified as C. difficile ribotype 027 by ribotyping, toxinotyping, and tcdC gene sequencing, which turned out the same pathogen as the epidemic hypervirulent B1/NAP1 strain. This is the first case of C. difficile PCR ribotype 027 in Korea. After discharge, she was maintained on probiotics and rifaximin for 3 weeks. She had no relapse for 6 months.

The quality assurance (QA) is of utmost importance in biobanks when archived biomaterials are distributed to biomedical researchers. For sample authentication and cross-contamination detection, the two fundamental elements of QA, STR genotyping is usually utilized. However, the incorporated number of STR markers is highly redundant for biobanking purposes, resulting in time and cost inefficiency. An index to measure the cross-contamination detection capability of an STR marker, the mixture probability (MP), was developed. MP as well as other forensic parameters for STR markers was validated using STR genotyping data on 2328 normal Koreans with the commercial AmpFlSTR kit. For Koreans, 7 STR marker (D2S1338, FGA, D18S51, D8S1179, D13S317, D21S11, vWA) set was sufficient to provide discrimination power of ~10(-10) and cross-contamination detection probability of ~1. Interestingly, similar marker sets were obtained from African Americans, Caucasian Americans, and Hispanic Americans under the same level of discrimination power. Only a small subset of commonly used STR markers is sufficient for QA purposes in biobanks. A procedure for selecting optimal STR markers is outlined using STR genotyping results from normal Korean population.

BACKGROUND: Clostridium difficile is the main etiologic agent of antibiotic-associated diarrhea and the most common cause of hospital-acquired diarrhea. Recently, the incidence of C. difficile infections (CDI) has increased and new highly virulent C. difficile strains have emerged. Therefore, accurate and rapid diagnosis is needed. We compared the results of using chromID C. difficile (chromID CD, bioMerieux, France) with the conventional C. difficile Selective Agar (CDSA; BD, USA) for the isolation of C. difficile. METHODS: A total of 738 stool specimens of suspected CDI patients at the Severance Hospital from July to August 2011 were inoculated onto CDSA. Among them, 104 stool specimens revealed colonies on CDSA that were then re-inoculated onto chromID CD. The stool samples were stored at -20degrees C until the time of the re-inoculation. Cultured agars were interpreted after 24 hrs and 48 hrs, respectively. Species identification was performed on the basis of colony characteristics on agar plates as well as the ATB 32A system (API System SA, France). RESULTS: The recovery rates of CDSA and chromID CD were 30.1% and 77.5% after 24 hrs, and 77.5% and 98.6% after 48 hrs, respectively. All of the C. difficile isolates were recovered as typical gray/black colonies on chromID CD. CONCLUSION: The performance of chromID CD for the isolation of C. difficile was better than that of conventional CDSA. The chromID CD could provide easy and sensitive detection of C. difficile even after 24hrs of incubation.
