Laryngoscopy and intubation cause an adrenergic response manifested by tachycardia and hypertension. Various phamacological agents have been administered prior to induction in an attempt to attenuate the adrenergic response but they all have limitations. The objective of our study was to determine if esmolol would be equally effective when adrninistered in a bolus with and without fentanyl. A double-blind, randomized trial was conducted in sixty ASA physical status 1 patients undergoing elective surgery. All patients were premedicated with 0.2 mg/kg diazepam orally and glycopyrrolate 0.04 mg/kg intramuseularyly 1 hour beforehand. Induction of anesthesia was accomplished with 4 mg/kg thiopental intravenously foUowed immediately by 0.15-0.2 mg/kg vecuronium and study drug (placebo, esmolol 150 mg, esmolol 150 mg and fentanyl 100 mcg). Endotracheal intubation was performed at 2 minutes after study drug adrninistration. Anesthesia was maintained with 1 MAC (+/-10%) isoflurane in 60% nitrous oxide in oxygen at a 5 L/min flow for 6 minutes. Heart rate and blood pressure were measured every minute by an automatic recording device. After laryngoscopy and intubation, maximum increase in stolic blood pressure above awake levels was 33 mmHg (p<0.05) and 14 mmHg (p<0.05) in esmolol 150 mg, esmolol 150 mg with fentanyl 100 mcg respectively, whereas systolic blood pressure increased 62 mmHg after tracheal intubation in patients with placebo. In six patients with esmolol 150 mg, rate-pressure product reached a level considered potentially dangerous to patients with coronary artery disease. However, when used with fentanyl, esmolol provides effectvie protection against the adrenergic response and increase of the rate-pressure product to laryngoscopy and intubation.

Hearing loss in the contralateral functioning ear is a rare and distressing complication after vetibular schwannoma removal. Various possible mechanisms have been proposed, however, the etiology of hearing loss is not clear. Fortunately, this is an extremely rare occurrence, sporadic case reports have appeared in the literatures. We report two cases of acute contralateral hearing loss after vestibular schwannoma removal and discuss the possible mechanisms of the phenomenon. Although permanent deafness may result, in our cases, the hearing loss was temporary, returning to near preoperative level within one month. The etiology of hearing loss in one case is thought to be cerebrospinal fluid leakage. However, in the other case, the cause of hearing loss is not clear. A better understanding of these events may lead to preventive measures to avoid contralateral hearing loss after vestibular schwannoma removal.

Skin metastasis from carcinoma of uterine cervix is extremely rare and its incidence is reported as 0.1~1.3%. Common pattern of occurrence is multiple nodules in abdomen, external genitalia, or lower extremeties. It is believed that the pathogenesis of skin metastasis is a result of retrograde spread of the tumor secondary to lymphatic obstruction. Treatment of skin metastasis may consist of surgical excision, local irradiation, or chemotherapy, but the prognosis is very poor and median survival is about 3 months. We have experienced such a case and report the case with brief review of literatures.

PURPOSE: Mechanical thrombectomy using a Solitaire stent has been associated with a high recanalization rate and favorable clinical outcome in intra-arterial thrombolysis. To achieve a higher recanalization rate for mechanical Solitaire thrombectomy, we used an intra-arterial low-dose booster tirofiban injection into the occluded segment after stent deployment. We report the safety and recanalization rates for mechanical Solitaire thrombectomy with a low-dose booster tirofiban injection. MATERIALS AND METHODS: Between February and March 2013, 13 consecutive patients underwent mechanical Solitaire thrombectomy with low-dose booster tirofiban injection. The occlusion sites included the proximal middle cerebral artery (5 patients), the internal carotid artery (5 patients), the top of the basilar artery (2 patients) and the distal middle cerebral artery (M2 segment, 1 patient). Six patients underwent bridge treatment, including intravenous tissue plasminogen activator. Tirofiban of 250 µg was used in all patients except one (500 µg). All occluded vessels were recanalized after 3 attempts at stent retrieval (1 time, n=9; 2 times, n=2; 3 times, n=2). RESULTS: Successful recanalization was achieved in all patients (TICI 3, n=8; TICI 2b, n=5). Procedural complications developed in 3 patients (subarachnoid hemorrhage, n=2; hemorrhagic transformation, n=1). Mortality occurred in one patient with a basilar artery occlusion due to reperfusion brain swelling after mechanical Solitaire thrombectomy with low-dose booster tirofiban injection. Favorable clinical outcome (mRS≤2) was observed in 8 patients (61.5%). CONCLUSION: Our modified mechanical Solitaire thrombectomy method using a low-dose booster tirofiban injection might enhance the recanalization rate with no additive hemorrhagic complications.

Chaenomeles sinensis is known to inhibit the development and progression of many age-related diseases, but the underlying molecular mechanisms are largely unclear. In the present study, we observed that the ethanol extract of Chaenomeles sinensis scavenged 2,2’-diphenylpicrylhydrazyl and 2,2’-azinobis diammonium radicals in vitro. The ethanol extract of Chaenomeles sinensisactivated antioxidant response element-luciferase activity and induced expression of NRF2 target genes in HaCaT cells. The ethanol extract of Chaenomeles sinensis also suppressed LPS-induced expression of COX-2 and iNOS proteins, and mRNA expression of TNF-α and IL-2 in RAW264.7 cells. Finally, the ethanol extract of Chaenomeles sinensis significantly suppressed testosterone propionate-induced benign prostatic hyperplasia in mice. Together, our study provides the evidence that the ethanol extract of Chaenomeles sinensis inhibits the development of benign prostatic hyperplasia by exhibiting anti-oxidant and anti-inflammatory effects.

The cystic teratoma is the most common germ cell tumors in reproductive age women. The malignant change of cystic teratoma is rare, about 1~2%, and mostly change to squ-amous cell carcinoma. We experienced 4 cases of squamous cell carcinoma arising in cystic teratoma and re- port our cases with a brief review of the literature.

PURPOSE: To measure the orbital volume from facial CT scans using a semi-automatic computer program. METHODS: Axial and coronal slices of 35 facial CT scans were used to measure the orbital volume. The cross-sectional area was determined from each slice using a semi-automated computer program (MATLAB 2009a). Next, the orbital volume was calculated from serial reconstruction of the cross-sections. RESULTS: The measured value in males was 26.34 +/- 3.09 cm3 in the right orbit and 26.30 +/- 3.21 cm3 in the left orbit from axial scans, and 26.58 +/- 2.76 cm3 in the right orbit and 26.59 +/- 2.75 cm3 in the left orbit from coronal scans. In females, the values were 23.84 +/- 2.29 cm3 in the right orbit and 23.89 +/- 2.33 cm3 in the left orbit from axial scans, and 24.06 +/- 2.90 cm3 in the right orbit and 24.10 +/- 2.82 cm3 in the left orbit from coronal scans. There was high positive correlation (r = +0.832, p = 0.0001) in measured orbital volume between axial and coronal scans. CONCLUSIONS: The orbital volume measurement from facial CT scans using a semi-automatic computer program is very useful. This method should prove useful in further studies examining the correlation of orbital volume variation in many ophthalmologic disorders.
