In the last decade, advances in laparoscopic equipments have allowed the development of laparoscopic surgical treatment for gynecologic affeetion. The purpose of this study is to investigate the cardiovascular effects and blood gas changes during laparoscope assisted vaginal hysterectomy (LAVH) in Trendelenburg position and intraabdominal CO2 insufflation to obtain optimal surgical field. Mean arterial pressure (MAP), heart rate. SaO2, PaO2, end-tidal CO2 (ETCO2) PaCO2, pH, and peak airway pressure (PAP) were measured in twenty patients who underwent laparoscope assisted vaginal hysterectomy in Trendelenburg position and intraabdominal CO2 insufflation. Each measurement was taken immedistely after intubation (control), 15 minutes after Trendelenburg position, 30 minutes after CO2 insufflation, 15 minutes, 1 hour and 6 hrs. after CO2 deflation. ETCO2 and PAP were not measured 1 hour and 6 hrs. after deflation The results were as follows; 1) Mean arterial pressure and heart rate were decreased after Trendelenburg position, but increased after CO2 insufflation. 2) Arterial O2 saturation was decreased after CO2 insufflation, 1 hour after deflation 3) Arterial PO2 was decreased after CO2 insufflation. 4) End-tidal CO2 was increased after CO2 insufflation. 5) Arterial PCO2 was increased after CO2 insufflation compared to control value, but it was decreased at 15 minutes after CO2 deflation. Arterial PCO2 at 1 hour after CO2 deflation was higher than at 15 minutes after CO2 deflation and 6 hrs. after CO2 deflation. 6) Arterial pH was decreased after CO2 insufflation. 7) Peak airway pressure was increased after Trendelenburg position and after CO2 insufflation.

A 60-year-old male was referred to the ophthalmologic clinic with aggravated anterior uveitis and corneal edema despite the use of topical and systemic steroids. He had undergone cataract surgery in both eyes 15 years previous. Slit lamp examinations revealed a retained lens fragment in the inferior angle of the anterior chamber, with severe corneal edema and mild anterior uveitis. The corneal edema and uveitis subsided following surgical extraction of the lens fragment. That a retained lens fragment caused symptomatic anterior uveitis with corneal edema 15 years after an uneventful cataract surgery is unique. A retained lens fragment should be considered as one of the causes of anterior uveitis in a pseudophakic patient.

Laryngoscopy and endotracheal intubation are potent stimuli that can induce increased sympathetic activity, tachycardia and hypertension. The authors studied the effects of intravenous clonidine pretreatment, a centrally acting a2-adrenoceptor agonist, on hemodynamic responses to laryngoscopy and tracheal intubation, and on anesthetic requirements during operation. Forty ASA I -II patients undergoing elective minor general surgery were allocated randomly to receive either 5ug/kg clonidine or 3 ml of 0.9% normal saline as control intravenously 10 minutes before induction of anesthesia. The results obtained were as follows. Compared to baseline values, blood pressure and heart rate at 1 minute after intubation were significantly increased in control group, but significantly decreased in clonidine group. They were maintained at lower values throughout the whole duration of operation in clonidine group than in control group. More doses of fentanyl were needed in the control group but not in the clonidine group during operation, and because of bradycardia and hypotension, atropine or ephedrine was needed in the clonidine group. In conclusion, the elevation of blood pressure and heart rate accompanying tracheal intubation were preventable with less requirement of supplemental fentanyl, but bradycardia and hypotention were infrequently seen as a side effects, when 5ug/kg intravenous injection of clonidine 10 minutes before induction.

BACKGROUND AND OBJECTIVES: To evaluate the brain MR angiography(MRA) as a tool of diagnosis and follow up study in acute ischemic stroke. METHODS: We reviewed 90 patients of acute ischemic stroke who received thrombolytic therapy and underwent brain MRI with MRA from September 1994 to July 1995. They were divided into two groups according to carotid system and vertebrobasilar system and then positive MRA findings were defined as stenosis or occlusion of vessels in relation with MRI lesions. RESULTS: The positive MRA was shown more than 80% in large arteries and lower than 23% in small arteries. And also the MRA was shown the degree stenosis and underlying vessel abnormalities but could not precisely analyze the degree of improvement of vascular patency in this study. CONCLUSIONS: The MRA as a routine method addition to the MRI provides relatively reliable and noninvasive screening test and provides information that can be more complete evaluation and prognosis in patients of acute ischemic stroke.

BACKGROUND: Endoscopic ultrasound-guided fine needle aspiration cytology (EUS-FNAC) is currently the most commonly used procedure for obtaining cytologic specimens of the pancreas. It is accurate, minimally invasive, safe and cost-effective. However, there is discrepancy between cytological and surgical diagnoses. This study was aimed at evaluating the diagnostic accuracy of EUS-FNAC of the pancreas. METHODS: We performed a retrospective review of 191 cases of pancreatic lesions initially diagnosed by EUS-FNAC with subsequent histological diagnosis between 2010 and 2012 in the Department of Pathology, Seoul National University Hospital. Cytologic and surgical diagnoses were categorized into five groups: negative, benign, atypical, malignant, and insufficient for diagnosis. Subsequently, 167 cases with satisfactory yield in both surgical and cytology specimens were statistically analyzed to determine correlations with diagnosis. RESULTS: In comparison to surgical diagnoses, cytologic diagnoses were true-positive in 103 cases (61.7%), true-negative in 28 cases (16.8%), false-positive in 9 cases (5.4%), and false-negative in 27 cases (16.1%). The diagnostic accuracy was 78.4%, sensitivity was 79.2%, and specificity was 75.7%. The positive predictive value was 92.0%, and negative predictive value was 50.9%. CONCLUSIONS: EUS-FNAC has high accuracy, sensitivity, specificity and positive predictive value. Overcoming the limitations of EUS-FNAC will make it a useful and reliable diagnostic tool for accurate evaluation of pancreatic lesions.

BACKGROUND: Markedly reduced urine have been commonly observed during mastoidectomy under general anesthesia. The aim of study was to evaluate the surgery-related mechanism of reduced urine during mastoidectomy. METHODS: 11 patients undergoing mastoidectomy were studied. Blood samples were drawn from CVP line inserted through right internal jugular vein just before drilling (Pre-D); at 15 min after drilling (D-15); at the time closest to the inner ear (CHP-1); at 15 min (CHP-2) and 30 min (CHP-3) after CHP-1 and just before emergence (End). MAP, HR, temperature, CVP, and urine output (UO) were recorded at each period. 0.9% normal saline with room temperature was used to irrigate surgical field. Serum ADH, and the osmolalities (serum and urine) were measured. In 6 patients, serum TSH and FSH were measured, simultaneously. RESULTS: There were no significant hemodynamic changes during procedure. UO was decreased in 50% during and after the drilling. No differences showed in UO between before and after the drilling of CHP. Plasma ADH level after the CHP was increased 2-3 fold than before. Serum osmolality was unchanged throughout the periods, while the urine osmolality was significantly increased after the period of CHP. FSH was not changed during the periods and TSH was decreased slightly than in Pre-D. CONCLUSIONS: The reduced urine output during mastoidectomy may be influenced by the drilling-related vibration, which may affect the supraoptico-hypophyseal tract, resulting in ADH release. The irrigated isotonic saline with higher osmolality (308 mOsm/kgH2O) than plasma osmolality may partly contributed to the increased ADH.

A dissecting aneurysm of the vertebral artery may be treated conservatively, surgically, or using an endovascular approach. Proximal clipping, wrapping or trapping are surgical treatment methods, and endovascular treatment with coils and balloons is performed where a dissecting aneurysm is located near the midline or the appropriate surgical manipulation is difficult. As the contralateral vertebral artery of this patient was hypoplastic, the stent-assisted coil embolization technique was employed to preserve the ipsilateral vertebral artery. We describe a clinical case of dissecting aneurysm of the vertebral artery occurring in a patient in whom a hypoplastic contralateral vertebral artery was successfully treated.

OBJECTIVES: According to preceding studies, many people with mental disability have unbalanced dietary habits or excessive intake of calories. Most of them are overweight or obese due to lack of self-control for food consumption, swallowing with inadequate chewing and physical inactivity. Therefore, this study aimed to assess the nutritional intake, including carotenoid, in mentally disabled people and find out a possible solution for nutritional improvement. METHODS: People with intellectual disability (N=28), emotional disability (N=44) participated in this study. The disorder grades were from I to III and ages were between 20 and 65 years. Assessments included anthropometry, daily intake of nutrients, including carotenoid, ROMA III questionnaire for assessing bowel movement. RESULTS: The average BMI of intellectually disabled people and emotionally disabled people was in the range of overweight and obesity respectively (23.7 +/- 6.3 kg/m2, 25.8 +/- 4.1 kg/m2). Overall, the frequencies of vegetable and dairy product intakes were lower in this population. When compared with Recommended Nutrient Intake (RNI) from Dietary Reference Intakes for Koreans 2010, the intakes of vitamin B1, vitamin B2 and calcium were insufficient in both groups. Also, lycopene intakes of carotenoid were low, compared with traditional Korean diet of the non-disabled people from the second year 2008 of the 4th National Health and Nutrition Survey. In addition, emotionally disabled people also had lower intake of cryptoxanthin. CONCLUSIONS: The mentally disabled people in this study showed lower intakes of vitamin B1, vitamin B2, calcium and carotenoids. Based on these findings, we recommend that it is important to encourage mentally disabled people to consume sufficient amounts of such nutrients in order to promote nutritional status.
