Photorefractive keratectomy (PRK), Keratomileusis In Situ (KM), Laser Assisted In Situ Keratomileusis (LASIK), and clear lens extraction have been performed for high myopic patients. Among the above surgical procedures KM and LASIK are applied to young patients in general. However, comparison of clinical results of these two procedures was not reported yet in Korea. To evaluate the clinical results of KM (n=16) and LASIK (n=11) for high myopic patients between -15 diopter (D) and -23 diopter (D), spherical equivalent (S.E) and uncorrected visual acuity were studied for more than ten months, retrospectively. The mean S.E. was changed from -17.36 D before operation to -3.70 D ten months after operation in KM, whereas it was from -17.41 D to -0.31 D in LASIK. At ten months after operation, uncorrected visual acuity equal or better than best corrected visual acuity before operation was 43. 8% in KM and 63. 6% in LASIK. This results show that the clinical result of LASIK were superior to that of KM for high myopia.

BACKGROUND: Many physicians hesitate to discuss do-not-resuscitate (DNR) orders with patients or family members in critical situations. In the intensive care unit (ICU), delayed DNR decisions could cause unintentional cardiopulmonary resuscitation, patient distress, and substantial cost. We investigated whether the timing of DNR designation affects patient outcome in the medical ICU. METHODS: We enrolled retrospective patients with written DNR orders in a medical ICU (13 bed) from June 1, 2014 to May 31, 2015. The patients were divided into two groups: early DNR patients for whom DNR orders were implemented within 48 h of ICU admission, and late DNR patients for whom DNR orders were implemented more than 48 h after ICU admission. RESULTS: Herein, 354 patients were admitted to the medical ICU and among them, 80 (22.6%) patients had requested DNR orders. Of these patients, 37 (46.3%) had designated DNR orders within 48 hours of ICU admission and 43 (53.7%) patients had designated DNR orders more than 48 hours after ICU admission. Compared with early DNR patients, late DNR patients tended to withhold or withdraw life-sustaining management (18.9% vs. 37.2%, p = 0.072). DNR consent forms were signed by family members instead of the patients. Septic shock was the most common cause of medical ICU admission in both the early and late DNR patients (54.1% vs. 37.2%, p = 0.131). There was no difference in in-hospital mortality (83.8% vs. 81.4%, p = 0.779). Late DNR patients had longer ICU stays than early DNR patients (7.4 ± 8.1 vs. 19.7 ± 19.2, p < 0.001). CONCLUSIONS: Clinical outcomes are not influenced by the time of DNR designation in the medical ICU. The late DNR group is associated with a longer length of ICU stay and a tendency of withholding or withdrawing life-sustaining treatment. However, further studies are needed to clarify the guideline for end-of-life care in critically ill patients.

We report a case of solitary congenital calcified nodule of the ear in a 1-year-old female. The lesion was a 2 X 2mm-sized, elevated, slightly erythematous and whitish-centered nodule located since birth on the superior helical rim of her left ear. Histopathological findings fram the totally excised lesion showed calcium deposits as amorphous, basophilic masses in the upper dermis and focal discharge of calcium by means of transepidermal elimination. Surrounding the calcium deposits, lymphohistiocytic infiltrations were present.

BACKGROUND: Drug reactions are common problems in hospital inpatients and outpatients. Reliable diagnosis is essential but often difficult. OBJECTIVE: This study attempts to define the clinical features and causative drugs in the patients with drug eruptions, and to evaluate the diagnostic value of skin tests. METHODS: Sixty one patients with drug eruptions were reviewed clinically. In 18 patients, patch and prick tests were performed using suspected drugs. RESULTS: 1. The highest incidence of drug eruptions was observed in the third and forth decades(44.2%) and there was no sexual prodominence. 2. The most frequent latent peroid was 4 hours to 1 week(49.2%). 3. The common morphological features were exanthematous eruptions(57.3%), urticaria(14.8%) and fixed drug eruptoins(11.5%). 4. The major causative drugs were antibiotics(cephalosporin, ampicillin), antipyretics/anti-inflammatory analgesics(aspirin, piroxicam) and CNS depressants(diphenylhydantoin). 5. Clinical manifestations according to possible causative drugs were as follows; exanthematous eruptions by antibiotics, antipyretics/analgesics, herbs, CNS depressants, propylthiouracil and captopril; urticaria by antibiotics and herbs; fixed drug eruption by sulfonamide, antipyretics/analgesics and phenobarbital; acneiform eruptions by diphenylhydantoin and isoniazid; Stevens-Johnson syndrome by ampicillin, sulfonamide, aspirin and piroxicam, erythema nodosum by sulfonamide, and lichenoid drug eruptions by propylthiouracil. 6. Positivity to patch and prick tests was shown in 2 of the 18 patients and in 1 of 18 patients, respectively. CONCLUSIONS: The most frequent clinical feature of the drug eruptions were exanthematous in nature and the most common causative drugs were antibiotics, as suspected. To search for the causative drug of the drug eruption, the only usual methods of patch and prick tests were not sufficient in our study.

Eosinophilic panniculitis is characterized by a prominent infiltration of numerous eosinophils in subcutaneous fat, and has been identified in patients with a variety of associated clinical conditions. A case of eosinophilic panniculitis in a 20-year-old woman with a history of atopic dermatitis is reported. She later developed superior sagittal sinus thrombosis, and we stress the importance of systemic evaluations in patients with eosinophilic panniculitis.

Severe sepsis and septic shock are the main causes of death in critically ill patients. Early detection and appropriate treatment according to guidelines are crucial for achieving favorable outcomes. Endotoxin is considered to be a main element in the pathogenic induction of gram-negative bacterial sepsis. Polymyxin B hemoperfusion can remove endotoxin and is reported to improve clinical outcomes in patients with intra-abdominal septic shock, but its clinical efficacy for pneumonic septic shock remains unclear. Here, we report a case of a 51-year-old man with pneumonic septic shock caused by Pseudomonas aeruginosa, who recovered through polymyxin B hemoperfusion.

BACKGROUND AND PURPOSE: The purpose of this study is to compare two clinical predictive rules, the pre-arrestmorbidity(PAM) index and the prognosis-after-resuscitation(PAR) score, which predict failure to survive following in-hospital cardiopulmonary resuscitation(CPR). METHOD: The study population consisted of 162 consecutive adult patients who underwent CPR at Wonju Christian Hospital over a year period. The PAM index and PAR score were calculated from the most recent data available for each variable prior to cardiac arrest. Each predictive tool was compared between the group of discharge alive and the group of in-hospital mortality. Performance of the predictive scores was also compared by receiver-operating characteristic(ROC) curves where appropriate. RESULTS: PAM index of study population was 4.39+/-2.69 and PAR score was 2.99+/-3.36. PAM index in the group of discharge alive was 1.87+/-2.79, and PAM index in the group of ih-hospital mortality was 4.51+/-2.62. PAR score in the group of discharge alive was 0.75+/-1.75, and PAR score in the group of in-hospital mortality was 3.1+/-3.4. The PAM index identified 15 patients with a score>8, while the PAR score identified 39 patients with a score>4, none of whom survived. The sensitivity of the PAR score for the prediction of failure to survive was 25%, while that of the PAM index was 10%; neither index incorrectly identified a patient as a non-survivor who eventually survived. Both of predictive methods were not significantly different in the ROC curve. CONCLUSION: Although further confirmation is necessary, PAM index and PAR score may provide useful prognostic information to physicians and patients involved with decisions about do-no- resuscitate orders.

BACKGROUND: Plate fixation is the most commonly used technique for the treatment of shaft fractures of both forearm bones (SFBFBs). However, all fractures are difficult to treat with plate fixation because of soft tissue injuries, fracture patterns, or the patient's condition. The purpose of this study is to compare the functional results of plate fixation only and combined plate and intramedullary (IM) nail fixation in SFBFBs. METHODS: Fifty-nine cases of SFBFBs that were surgically treated from June 2007 to July 2012 were retrospectively reviewed. In this study, 47 cases that were followed up for more than 12 months were included. All SFBFBs were divided into two groups according to the methods used for internal fixation: plate fixation only (group A) and combined plate and IM nail fixation (group B). The fixation methods were determined intraoperatively. Plate fixation was considered as the first option in all cases, but combined plate and IM nail fixation was selected as the second option if it was difficult to be fixed with plate only. Groups A and B comprised of 31 and 16 cases, respectively. The functional results were evaluated by the Grace and Eversmann rating system and the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. RESULTS: In groups A and B, a radiologic union was achieved in 30/31 and 14/16 cases and average union time was 11.1 and 17.8 weeks, respectively. According to the Grace and Eversmann rating system, group A had excellent results in 15 cases, good in 14, acceptable in one, and unacceptable in one. Group B had excellent results in three cases, good in nine, acceptable in two, and unacceptable in two. The average DASH score was 7.1 points (range, 0 to 19.2 points) in group A and 15.1 points (range, 0 to 29.6 points) in group B. Three cases of nonunion with unacceptable results achieved a bony union by additional procedures and the functional results of these cases improved to good or excellent. CONCLUSIONS: The functional results and the average union time were superior in group A than in group B. However, we think that combined fixation is a useful method for SFBFBs that cannot be treated with plate fixation only.

Korean Journal of Anesthesiology 2013;65(2):127-131
BACKGROUND: Jaw-thrust is a noxious stimulus that might induce sympathetic responses. The purpose of this study, was to evaluate the effects of jaw-thrust on sympathetic responses. METHODS: We investigated seventy three patients. Patients who received general anesthesia were randomly divided into a control group (maintenance of combined airway maneuver with head tilt, open mouth by mouthpiece, and chin-lift, n = 30) and jaw-thrust group (maintenance of head tilt, open mouth and jaw-thrust, n = 30). In the jaw-thrust group, four minutes of endoscopy-guided force to the mandible to get the best laryngeal view were applied. For the control group, the combined airway maneuver was maintained during the same period. Arterial blood pressure (AP) and heart rate (HR) were recorded at predetermined time points (1 min before anesthesia induction, 2 min after fiberoptic bronchoscopy placement, and thereafter 1 min-interval during each airway maneuver) during jaw-thrust and chin-lift maneuver. The force amplitude applied for best laryngeal view during jaw-thrust was also measured. RESULTS: Peak systolic and diastolic AP increased 39.0 +/- 17.6 and 39.9 +/- 22.8 mmHg from the baseline (P < 0.001) in the jaw-thrust group. HR was also 32.5 +/- 19.4 beats/min from the baseline (P < 0.001) in the jaw-thrust group. These remained high at all time points, compared with the control group (P < 0.01). The force magnitude applied for jaw-thrust was not correlated to the AP and HR changes (P > 0.05). CONCLUSIONS: Performing the jaw-thrust maneuver induces significant sympathetic responses, irrespective of the force magnitude.

OBJECTIVE: The Positive and Negative Affect Schedule (PANAS) was developed as a measure of positive affect (PA) and negative affect (NA). The aim here is to examine the factor structure and concurrent validity of the Korean version of the Positive and Negative Affect Schedule (K-PANAS) in a clinical sample in Korea. METHODS: K-PANAS was administered to a clinical sample in Korea. Internal consistency, test-retest reliability, and confirmatory factor analysis (CFA) were undertaken to examine the factorial structure and reliability of the K-PANAS. RESULTS: The reliability of K-PANAS is satisfactory. CFA showed that several of the models commonly used in Western populations provided an insufficient fit. The modified model provided a more adequate fit to the data. CONCLUSION: The authors demonstrate that the K-PANAS has adequate psychometric properties, and that findings obtained in the West using PANAS were partially replicated.
