Objective : Massive intracerebral hemorrhage (ICH) and major infarction (MI) are devastating cerebral vascular diseases. Decompression craniectomy (DC) is a common treatment approach for these diseases and acceptable clinical results have been reported. Author experienced the postoperative intracranaial pressure (ICP) trend is somewhat different between the ICH and MI patients. In this study, we compare the ICP trend following DC and evaluate the clinical significance. Methods : One hundred forty-three patients who underwent DC following massive ICH (81 cases) or MI (62 cases) were analyzed retrospectively. The mean age was $56.3{\pm}14.3$ (median=57, male : female=89 : 54). DC was applied using consistent criteria in both diseases patients; Glasgow coma scale (GCS) score less than 8 and a midline shift more than 6 mm on brain computed tomography. In all patients, ventricular puncture was done before the DC and ICP trends were monitored during and after the surgery. Outcome comparisons included the ictus to operation time (OP-time), postoperative ICP trend, favorable outcomes and mortality. Results : Initial GCS (p=0.364) and initial ventricular ICP (p=0.783) were similar among the ICH and MI patients. The postoperative ICP of ICH patients were drop rapidly and maintained within physiological range if greater than 80% of the hematoma was removed. While in MI patients, the postoperative ICP were not drop rapidly and maintained above the physiologic range (MI=18.8 vs. ICH=13.6 mmHg, p=0.000). The OP-times were faster in ICH patients (ICH=7.3 vs. MI=40.9 hours, p=0.000) and the mortality rate was higher in MI patients (MI=37.1% vs. ICH=17.3%, p=0.007). Conclusion : The results of this study suggest that if greater than 80% of the hematoma was removed in ICH patients, the postoperative ICP rarely over the physiologic range. But in MI patients, the postoperative ICP was above the physiologic range for several days after the DC. Authors propose that DC is no need for the massive ICH patient if a significant portion of their hematoma is removed. But DC might be essential to improve the MI patients' outcome and timely treatment decision.

Purpose: To investigate adverse drug reactions (ADR) and causative drugs in the elderly 65 years of age or older, using Korean spontaneous reporting adverse events reporting database from June 2009 to December 2010. Methods: We estimated the association between ADRs and implicated medications by calculating a proportional reporting ratio (PRR), reporting odds ratio (ROR), and information component (IC). We reexamined the most frequently implicated medications and ADRs, and the seriousness of ADRs. Then, we assessed reports and concordant rate of ADRs due to medications designated as "high-risk" in elderly by 2012 healthcare effectiveness data and information set (HEDIS) or "potentially inappropriate" by 2012 American Geriatrics Society updated Beers criteria for potentially inappropriate medications (PIMs). Results: Among 15,484 elderly reports, data-mining analysis by PRR, ROR and IC showed that 421 drug-ADR pairs were detected as signals (3,189). The most frequently reported ADR and causative drug were urticaria (470) and contrast media agents (647), respectively. One hundred eighty nine ADR cases were graded as serious. Twenty-two kinds of high-risk medications were shown to be implicated in only 0.9% of ADRs. Only thirty-nine cases were consistent with 2012 Beers criteria or HEDIS. Conclusion: These results suggest that management of the other medications including contrast media agents as well as close monitoring of PIMs are necessary for reducing ADRs in the elderly.

Objective : This study assessed the efficacy of anterior cervical discectomy and fusion (ACDF) with cage alone compared with ACDF with plate instrumentation for radiologic and clinical outcomes in two-level cervical degenerative disease. Methods : Patients with cervical degenerative disc disease from September 2004 to December 2009 were assessed retrospectively. A total of 42 patients received all ACDF at two-level cervical lesion. Twenty-two patients who underwent ACDF with cage alone were compared with 20 patients who underwent ACDF with plate fixation in consideration of radiologic and clinical outcomes. Clinical outcomes were assessed using Robinson's criteria and posterior neck pain, arm pain described by a 10 point-visual analog scale. Fusion rate, subsidence, kyphotic angle, instrument failure and the degenerative changes in adjacent segments were examined during each follow-up examination. Results : VAS was checked during each follow-up and Robinson's criteria were compared in both groups. Both groups showed no significant difference. Fusion rates were 90.9% (20/22) in ACDF with the cage alone group, 95% (19/20) in ACDF with the plate fixation group (p = 0.966). Subsidence rates of ACDF with cage alone were 31.81% (7/22) and ACDF with plate fixation were 30% (6/20) (p = 0.928). Local and regional kyphotic angle difference showed no significant difference. At the final follow-up, adjacent level disease developed in 4.54% (1/22) of ACDF with cage alone and 10% (2/20) of ACDF with plate fixation (p= 0.654). Conclusion : In two-level ACDF, ACDF with cage alone would be comparable with ACDF with plate fixation with regard to clinical outcome and radiologic result with no significant difference. We suggest that the routine use of plate and screw in 2-level surgery may not be beneficial.

Purpose: We evaluated the clinical outcomes of the non-operative management of post-gastrectomy duodenal stump leakage in patients with gastric cancer. Materials and Methods: A total of 1,230 patients underwent gastrectomy at our institution between 2010 and 2014. Duodenal stump leakage was diagnosed in 19 patients (1.5%), and these patients were included in this study. The management options varied with patient condition; patients were managed conservatively, with a pigtail catheter drain, or by tube duodenostomy via a Foley catheter. The patients' clinical outcomes were analyzed. Results: Duodenal stump leakage was diagnosed in all 19 patients within a median of 10 days (range, 1~20 days). The conservative group comprised of 5 patients (26.3%), the pigtail catheter group of 11 patients (57.9%), and the Foley catheter group of 3 patients (15.8%). All 3 management modalities were successful; none of the patients needed further operative intervention. The median hospital stay was 18, 33, and 42 days, respectively. Conclusions: Non-operative management of duodenal stump leakage for selected groups of patients with gastric cancer was effective for control of intra-abdominal sepsis. This management modality can help obviate the need for surgical intervention.

Objectives: Warm needling combines simultaneously the effects of acupuncture and moxibustion. This study was to investigate whether warm needling could relieve acute knee arthritis induced by carrageenan in rats. Methods: To illuminate the underlying mechanisms of the warm needling-induced antinociception, weight bearing force (WBF) was observed on the acute knee arthritic rat model. Under general anesthesia, ST36, SP9, Hakjung extra point, LI4 were punctured and stimulated with 30 mg moxa ball combustion on top of the needle (${\emptyset}0.18{\times}8mm$). Results: In behavioral test, rats subsequently showed a reduced stepping force of the affected limb 3 hours after the induction of arthritis. Warm needling on the contralateral or ipsilateral ST36 failed to show antinociceptive effect on the acute knee arthritis. Warm needling on the contralateral SP9 or LI4 increased WBF values to normal level in the acute stage of the arthritis. Warm needling on the Hakjung extra-point resulted in the significant antinociceptive effects through acute stage. These effects of warm needling were suppressed by opioids receptor antagonist naltrexone (10 mg/kg, i.p.) and alpha adrenoceptor antagonist phentolamine (5 mg/kg, i.p.). Conclusion: The data suggest that warm needling-induced antinociception is differently mediated by acupoints and accomplished by activating the descending inhibitory systems including endogenous opioids and $\alpha$-adrenoceptors.

Purpose: To improve professional intensive care by analyzing admission causes, causes of death, disease conditions, and treatment processes in patients with hematological malignancies admitted to intensive care units (ICUs) in South Korea. Methods: This was a retrospective study approved by IRB, and conducted on admission with 559 adults, in the hematology ICU of a hospital located in Seoul. The study was carried out from April 2009 to March 2012. Data were analyzed using SAS. Results: Pneumonia was the most frequent cause of ICU admission and death, followed by sepsis. The condition at discharge was death (53.6%), recovery (39.9%), or hopeless (5.1%). Mortality of patients in states of incomplete remission was higher than that of patients with complete remission and of patients with multiple myeloma, severe aplastic anemia, and lymphoma. Conclusion: Results show that pneumonia and sepsis are the most frequent causes of ICU admission and for the death of patients with hematological malignancies. The most frequent status at discharge of patients with hematological malignancies was death (53.6%), with mortality of patients at Incomplete Remission status, of mechanically ventilated patients, and of patients on continuous renal replacement therapy (CRRT) being higher than others.

Stable poly(styrene-co-divinylbenzene) [P(St-co-DVB)] micro spheres with narrow size distribution were synthesized in the presence of 2,2'-azobis(2,4-dimethyl valeronitrile) (V-65) and co-initiator in an acetone/water mixture in the precipitation polymerization at $53^{\circ}C$ for 24 h. Potassium peroxodisulfate (KPS), ammonium peroxodisulfate (APS) and sodium peroxodisulfate (NaPS) were used as co-initiators. The optimum ratio of acetone to water for the formation of a narrow distribution of P(St-co-DVB) particles was 49:11 (g/g). The optimum co-initiator compositions for narrow distribution were 9:1 (g/g) for V-65 to KPS, 11:1 for V-65 to APS and 6:1 for V-65 to NaPS. The yield for these compositions was $54{\sim}57%$ and the largest particle size was obtained with the lowest zeta-potential and CV values. From the XPS measurements, the charge density was increased but the zeta potential decreased with increasing sulfur content, implying that the sulfate group provides the electrostatic stabilization on the particle surface. This suggested that the self-crosslinking between styrene and DVB, the electrostatic stabilization of initiators, and the balanced hydrophobic and hydrophilic properties of the solvents are responsible for the formation of stable P(St-co-DVB) spherical particles with narrow size distribution.

Purpose: We investigated the effect of overweight on luteinizing hormone (LH) levels after a gonadorelin stimulation test in Korean girls with idiopathic central precocious puberty (CPP). Methods: Medical records of 234 girls diagnosed with idiopathic CPP were reviewed retrospectively. CPP was diagnosed when the peak LH levels after gonadorelin stimulation was >5.0 U/L. The enrolled girls had a peak LH level >5.0 U/L after a gonadorelin stimulation test. Selected girls were classified as normoweight (body mass index [BMI] below the 85th percentile with respect to age) and overweight (BMI greater than the 85th percentile with respect to age). Results: The peak LH ($8.95{\pm}2.85U/L$ vs. $11.97{\pm}8.42U/L$, P<0.01) and peak folliclestimulating hormone ($9.60{\pm}2.91U/L$ vs. $11.17{\pm}7.77U/L$, P=0.04) after gonadorelin stimulation were lower in overweight girls with idiopathic CPP than in normoweight girls with idiopathic CPP. Being overweight was negatively associated with peak LH levels after gonadorelin stimulation test (odds ratio, 0.89; 95 % confidence interval, 0.81-0.98, P=0.02). Conclusion: In girls with idiopathic CPP, being overweight led to a lower LH peak after gonadorelin stimulation. Further research is needed to better understand the role of overweight on gonadotropin secretion in precocious puberty.
