Objective To study the value of clinical application of leukocyte classification alarm system (Q‐Flag ) for Sysmex XT‐1800i blood cell analyzer .Methods 394 blood samples with alarm system (Q‐Flag) and 190 ones without abnormal alarm infor‐mation detected by the Sysmex XT‐1800i blood cell analyzer were performed to observe the quantity and morphology of blood cells by manual differentiation ,and the results were compared between them .Results The alarm system of Sysmex XT‐1800i blood cell analyzer in detecting cell morphologic abnormalities was 100 .0% for sensitivity ,62 .3% for specificity ,70 .8% for positive predic‐tive value and 100 .0% for negative predictive value .Based on thegold standardof manual differentiation ,no abnormal cells were observed in those blood samples without Q‐Flag alarm information and the coincidence rate was 100% .The coincidence rate of leu‐kocyte classification was from 0 .0% to 75 .0% for blood cell analyzer when the alarm system (Q‐Flag) was between 100U and 200U ,and that was from 66 .7% to 95 .6% when the alarm system (Q‐Flag) was between 200U and 300U .Conclusion The alarm system sensitivity of leukocyte classification alarm system (Q‐Flag) is high for Sysmex XT‐1800i blood cell analyzer ,and it is nec‐essary to manually differentiate the samples with abnormal Q‐Flag in order to provide accurate and reliable clinical diagnostic infor‐mation .

BACKGROUND: Proximal humerus fracture is considered to be the third most common fracture for patients aged 65 years or older. Conservative treatment has been known to treat most of humerus fracture. However, fractures with severe displacement or dislocation may require surgical treatment. Intramedullary fibular allograft with a locking plate is frequently used in patients accompanying medial metaphyseal disruption. In this study, author intends to evaluate clinical and imaging results based on patients who underwent surgical treatment using fibular allograft with a locking plate. METHODS: This study is conducted prospectively at Wonju Severance Christian Hospital, targeting patients who previously underwent surgical treatment using open reduction and intramedullary fibular allograft with a locking plate between 2011 and 2015. A total of 26 patients were evaluated on the following: postoperational clinical assessment measuring Constant score, American Shoulder and Elbow Society (ASES) score, and the Disabilities of the Arm, Shoulder and Hand (DASH) score. Postoperational imaging assessments are evaluated via measuring the neck-shaft angle. The study subject were Neer classification type 3, 4 proximal humerus fracture cases with disrupted medial hinge and having cortical comminution in the region of the surgical neck. RESULTS: The average period of progression was 22.5 months, and the average age of patients was 72.6 years. At the final follow-up, the average Constant, average ASES, and average DASH scores were 80.1, 78.5, and 20.6 respectively. The average neck-shaft angle was 127.5°. CONCLUSIONS: In conclusion, fibular allograft augmentation with a locking plate showed satisfying results in both clinical and imaging studies.

Objective To investigate the dynamic changes of the spinal cord during neck flexion in Hirayama disease for diagnosis.Methods MRI examinations in neutral neck position and a fully flexed neck position were performed on 18 cases of Hirayama disease and 31 young normal control subjects.We measured an antero-posterior diameter(APD)and transverse diameter(TD)of the cervical cord at the superior margin of the C6 vertebral body for each position,and investigate the dynamic changes.The different in frequency of these findings between the control and patient groups was examined by means of the x~2 test.The group means were compared by independent-sample t-test.Significance was defined as P

The most frequently reported neurological complication of a wasp sting is ischemic stroke. We
treated a patient with wasp sting with unusual complications. A 52-year-old man was hospitalized
for anaphylactic shock after multiple wasp stings. Although the patient recovered consciousness
after 2 days, he had global aphasia and right hemiparesis. Brain magnetic resonance imaging and
angiography revealed high-intensity signals in the left basal ganglia and cerebral cortex and stenosis
of the left middle cerebral artery. After 2 days, the middle cerebral artery stenosis improved. After 5
days, diffusion-weighted imaging showed an enlarged lesion in the left frontal cortex. The infarct in
this case was due to a predominantly unilateral vasoconstrictive hypoxic brain injury from wasp stings.

Hemorrhagic cystitis is a common stem cell transplantation-related complication. The incidence of early-onset hemorrhagic cystitis, which is related to the pretransplant conditioning regimen, has decreased with the concomitant use of mesna and hyperhydration. However, late-onset hemorrhagic cystitis, which is usually caused by the BK virus, continues to develop. Although the BK virus is the most common pathogenic microorganism of poststem cell transplantation late-onset hemorrhagic cystitis, pediatricians outside the hemato-oncology and nephrology specialties tend to be unfamiliar with hemorrhagic cystitis and the BK virus. Moreover, no standard guidelines for the early diagnosis and treatment of BK virus-associated hemorrhagic cystitis after stem cell transplantation have been established. Here, we briefly introduce poststem cell transplantation BK virus-associated hemorrhagic cystitis.

Respiratory syncytial virus (RSV) is the major cause of lower respiratory tract infection in infants. Life-threatening RSV infection is often reported in young children and immunocompromised hosts. Since there is no report on ribavirin therapy for RSV pneumonia in pediatric cancer patients in Korea, we report one case of RSV pneumonia that developed in an infant with acute lymphoblastic leukemia (ALL). Despite administration of oral ribavirin and intravenous immunoglobulin, the patient's respiratory distress worsened and admission to an intensive care unit was necessary. Chest x-ray showed multifocal consolidation, pneumothorax, and pneumomediastinum. Treatment with aerosolized ribavirin led to significant clinical improvement. The role of aerosolized ribavirin is still controversial, but it might have a therapeutic potential for severe RSV pneumonia in children with leukemia.

8.Analysis of Drug Utilization for Patients with Ankylosing Spondylitis.
Korean Journal of Clinical Pharmacy 2015;25(4):246-253
BACKGROUND & OBJECT: Ankylosing spondylitis (AS) is a chronic inflammatory disease that causes ankylosis and deformation of axial joints. Since current medicine cannot cure the disease yet, alleviating pain and preventing deformation with medications are the main therapy for patients with AS. The key medications for these purposes include nonsteroidal anti-inflammatory drugs (NSAIDs), and tumor necrosis factor-alpha (TNF-alpha) inhibitors. This study aims to analyze prescribing patterns of AS patients in South Korea. METHOD: National Patients Sample data compiled by the Health Insurance Review and Assessment Service from 2013 was analyzed. Patients with AS were identified with Korean Standard Classification of Diseases code-6, which was M45. The rates of prescription, discontinuation, and switching ingredients were calculated for each medication during 2013. RESULTS: Total number of patients was 655, and most of them were male (n = 514, 78.5%). Of all age groups, the proportion of 30-40 year old patients was the greatest (35.1%). The most utilized drug class was NSAIDs (82.4%). Less than half of patients were prescribed TNF-alpha inhibitors (n = 212, 32.4%). Meloxicam, aceclofenac, and celecoxib were the most frequently prescribed NSAIDs. In case of TNF-alpha inhibitors, adalimumab, etanercept and infliximab were the top three most prescribed drugs. Although not recommended by the current practice guideline, significant proportions of patients were identified using disease modifying anti-rheumatic drugs (DMARDs). CONCLUSION: Considering the current practice guideline and previous studies about the efficacy, the use of DMARDs should be reduced and medical insurance term in South Korea should be re-examined.
