The purpose of this article is to present the authors experience that simple calculating method of fracture area in blow out fracture. Authors set up a hypothesis that fracture shape is a isosceles triangle, rectangle or diamond shape. It was enable easily to calculating of fracture area with 2D facial CT scan only. Enophthalmos and fracture area of 22 patients was made inspection. We verified our experimental results with student t-test. We first concluded that new simple calculating method is usful but, need further evaluations and patients.

A hand-arm vibration syndrome, local vibration illness, occurs in some workers who use hand held vibration tools. It consists of white fingers, diffusely distributed finger neuropathy, pain in the hand and arm, and a small excess risk of osteoarthritis. This study is aimed to identify effective methods to confirm local vibration illness among various health exams, which are mentioned in worker's special health exam regulation. In addition, this study is aimed to quantitatively assess the daily vibration exposure level as a major determinant of vibration illness. The subjects, 46 vibration workers, were selected according to the results of the first special health exam about vibration hazards at shipbuilding industry in 1997. They all had experiences of work related blanching of fingers. Fifteen controls, who had no vibration exposure at all, were also recruited to compare their test results with the results of vibration workers. We adopted 1 subjective and 6 objective tests to evaluate the effectiveness and feasibility for confirming local vibration illness. These tests were history taking of subjective symptoms according to the Stockholm classification, checking blood pressure of finger, checking grasp power, checking finger skin temperature, nail-bed pressing test, vibration perceptional threshold test, and skin prick test for pain perception. Among these, checking skin temperature, nail-bed pressing test, and vibration perception test included cold water provocations. We also estimated some vibration exposure levels of hand held vibration tools by using previously published data from one automobile company. In conclusion, history taking of subjective symptoms according to the Stockholm classification, nail-bed pressing test, and vibration perceptional threshold test were discovered to be effective to diagnose local vibration illness. Furthermore, vibration perceptional threshold on right fingers showed a dose-response relationship to daily vibration exposure levels. The parameter beta was 0.0005(+/-0.0002), and statistically significant by REM (random effects model).

BACKGROUND: Patients with malignancy are considered to be at high risk of severe pandemic influenza A/H1N1 2009. This study was conducted to identify the severity of pandemic influenza A/H1N1 2009 among patients with malignancy. MATERIALS AND METHODS: Between August 2009 and December 2009, we reviewed clinical data and medical records of 31 patients with malignancy and 63 hospitalized patients without malignancy. RESULTS: Eighty-three patients with laboratory-confirmed pandemic influenza A/H1N1 2009 were admitted. The rate of ICU admission was higher among patients with malignancy (without malignancy 13% vs with malignancy 35%, P=0.024). The mortality rate was higher among patients with malignancy (without malignancy 6% vs with malignancy 25%, P=0.033). Patients using immunosuppressants showed a higher rate of lower respiratory tract infection (83% vs 24%, P=0.013). CONCLUSIONS: Pandemic influenza A/H1N1 2009 in patients with malignancy was more severe than in patients without malignancy.

BACKGROUND: This article reports annual data of intensive care units (ICU) module of the Korean Nosocomial Infections Surveillance (KONIS) system from July 2011 through June 2012. METHODS: We performed a prospective surveillance of nosocomial urinary tract infections (UTI), bloodstream infections (BSI), and pneumonia (PNEU) at 143 ICUs in 81 hospitals using the KONIS system. Nosocomial infection (NI) rates were calculated as the number of infections per 1,000 patient days or device days. Asymptomatic bacteriuria was excluded on or after October 1, 2011. RESULTS: A total of 3,374 NIs were found during the study period: 1,356 UTIs (1,336 cases were urinary catheter-associated), 1,253 BSIs (1,091 were central line-associated), and 765 PNEUs (481 were ventilator-associated). The rate of urinary catheter-associated UTIs (CAUTIs) was 2.26 cases per 1,000 device-days (95% confidence interval, 2.14-2.39) and urinary catheter utilization ratio was 0.85 (0.849-0.851). The rate of central line-associated BSIs was 3.01 (2.84-3.19) and the utilization ratio was 0.52 (0.519-0.521). The rate of ventilator-associated PNEUs (VAPs) was 1.70 (1.56-1.86) and the utilization ratio was 0.40 (0.399-0.401). Ventilator and urinary catheter utilization ratios were lower in the ICUs of hospitals with 400-699 beds than those in hospitals with 700-899 beds or more than 900 beds. Nevertheless, VAPs and CAUTIs were more common in hospitals with 400-699 beds. CONCLUSION: Nosocomial infection rates were similar to the findings of those of the previous period, July 2010-July 2011. Implementation of proven infection-control strategies are needed, especially in the hospitals having fewer than 700 beds.

Kaposi's sarcoma was the first malignancy to be recognized as a cancer defining acquired immunodeficiency syndrome (AIDS). Kaposi's sarcoma, a rare tumor, usually presents itself with skin lesions but it may be widely disseminated internally such as digestive, respiratory organ, spleen, or lymph node. The incidence of Kaposi's sarcoma in patients with AIDS has declined in the era of effective antiretroviral therapy (ART), and cases of disseminated Kaposi's sarcomas have rarely been reported in Korea. Chemotherapy is usually used in symptomatic or rapidly progressive disease, and interferon-alpha can be applied as a treatment option. We report a successfully treated case of gastrointestinal and cervical lymph nodal Kaposi's sarcoma in a patient with AIDS who had combined treatment with ART, interferon-alpha, and paclitaxel.

BACKGROUND: The Korean Society for Nosocomial Infection Control (KOSNIC) ran a surveillance system, called as Korean Nosocomial Infections Surveillance (KONIS), since July 2006. Here, we report the annual data of the intensive care unit (ICU) module of the system from July 2012 through June 2013. METHODS: This is a prospective surveillance of nosocomial urinary tract infections (UTI), bloodstream infections (BSI), and pneumonia (PNEU) at 161 ICUs in 91 hospitals using the KONIS system. The nosocomial infection (NI) rate was calculated as the number of infections per 1,000 patient days or device days. RESULTS: A total of 3,042 NIs were reported during the study period: 877 UTIs (854 cases were urinary catheter-associated), 1,272 BSIs (1,096 were central line-associated), and 893 PNEUs (526 cases were ventilator-associated). The rate of urinary catheter-associated UTIs (CAUTIs) was 1.26 cases per 1,000 device days (95% confidence interval; 1.18-1.34) and urinary catheter utilization ratio was 0.78 (0.779-0.781). The rate of central line-associated BSIs was 2.57 (2.42-2.72) and the utilization ratio was 0.49 (0.489-0.491). The rate of ventilator-associated PNEUs was 1.64 (1.50-1.78) and the utilization ratio was 0.37 (0.369-0.371). The urinary catheter utilization ratio was lower in the ICUs of hospitals with 400-699 beds than in those of hospitals with more than 900 beds; nevertheless, CAUTIs were more common in the hospitals with 400-699 beds. The central line-associated BSI (CLABSI) rate was lower in the study period than in the previous period of July 2011-June 2012 [2.57 (2.42-2.72) vs. 3.01 (2.84-3.19)]. CONCLUSION: The CLABSI rates were lower in the study period than those in the previous years. CAUTIs were more common in the ICUs of hospitals with 400-699 beds than in those of larger hospitals.
