BACKGROUND: The laparoscopy requires carbon dioxide (CO2) insufflation and Trendelenburg position for operational convenience. However, the above circumstances affect the cardiopulmonary systems significantly and intraocular pressure (IOP) may be also influenced. METHODS: In 27 non-glaucoma patients right and left intraocular pressure (RIOP, LIOP) were measured 5 minutes after induction of general anesthesia (control value), 15 and 30 minutes after CO2 insufflation and endelenburg-lithotomy position. RESULTS: The control values of RIOP and LIOP were 11.3 4.7 mmHg and 11.5 4.7 mmHg respectively. At 15 minutes after CO2 insufflation and Trendelenburg-lithotomy position, they increased to 16.6 5.3 mmHg and 17.0 5.9 mmHg (p<0.05). At 30 minutes, 18.4 3.5 mmHg and 18.2 4.1 mmHg (p<0.05). CONCLUSION: CO2 insufflation and Trendelenburg-lithotomy position increase IOP significantly in non-glaucoma patients during laparoscopy.

BACKGROUND: Postintubational sore throat and hoarseness are usually mild symptoms but they are very common complaints among the patients after endotracheal general anesthesia. In addition, some might have severe discomfort and need invasive procedure to relieve these problems. We tried new method of endotracheal tube cuff filling with local anesthetics to reduce postoperative sore throat and hoarseness and evaluated the results. METHODS: Endotracheal cuff filling was done with air 5 ml in healthy 20 patients (ASA I-II, control group). And in another healthy (ASA I-II) 35 patients, the cuffs were filled with 4% lidocaine 3.5 ml and 8.4% sodium bicarbonate 1.5 ml mixture. After 24 hours following general anesthesia, patients were visited and asked whether there were sore throat or hoarseness, if any, how the degree was. RESULTS: In lidocaine-treated group, the incidence of postintubational sore throat was less compared to control group significantly. There was no difference in incidence of hoarseness between two groups. CONCLUSION: Endotracheal cuff filled with lidocaine and sodium bicarbonate mixture is suggested as an effective protective method that reduces the frequency of postintubational sore throat.

BACKGROUND: Total intravenous anesthesia (TIVA) is one of the anesthetic techniques that needs no inhalational agent but only an intravenous agent for induction and maintenance of anesthesia. Among drugs used in TIVA, propofol is the most popular agent. Rapid emergence and antiemetic characteristics of propofol are well known advantages but a dose dependent cardiovascular depressant effect is one of the disadvantages of this drug. Otherwise, ketamine, a dissociative agent, has been restricted in its use because of bad dreams, delirium and delayed emergence even though it has profound analgesic characteristics. However, ketamine has a stimulatory effect on the cardiovascular system, so it can raise blood pressure and pulse rate and in the case of TIVA, these properties can be advantageous when used with propofol. This study was aimed to decide whether TIVA using propofol and ketamine would have more stable vital signs during anesthesia and more rapid and smoother emergence in comparison with inhalational anesthesia using isoflurane. METHODS: Thirty two patients scheduled for elective general anesthesia were randomly allocated into two groups; I (inhalational anesthesia using isoflurane) group and PK (TIVA using propofol and ketamine) group. I group was controlled with isoflurane 1 - 1.5 vol% and the PK group was controlled with propofol 3 - 12 mg/kg/hr and ketamine 0.5 - 1.0 mg/kg/hr. Arriving at the recovery room, a single observer recorded the time to spontaneous movement, responses to painful pinch and verbal command, and orientation to age, name, place, date and time. At 5, 10, and 30 minutes after anesthesia, a PARS (postanesthesia recovery score), count-down test, and VAS (visual analogue scale) were checked. Postoperative events were checked in the recovery room and 24 hours lator. RESULTS: There was no significant difference in demographic data or characteristics of operation. Compared with the I group, the PK group had significantly rapid orientation responses on place, date and time. Restoration in the count-down test was more rapid in the PK group after 10 minutes in the recovery room. The VAS was lower in the PK group after 30 minutes in the recovery room. CONCLUSIONS: TIVA using propofol and ketamine has a more rapid emergence than inhalational anesthesia using isoflurane and better postoperative analgesic effect without respiratory depression.

Chios Gum Mastic (CGM) is a natural resin extracted from the leaves of Pistacia lentiscus, a plant endemic to the Greek island of Chios. It has been used by traditional healers, and it has antibacterial, antifungal properties, and therapeutic benefits for the skin. The CGM reduces the formation of dental plaque and bacterial growth in oral saliva, and recent studies have demonstrated the role of antioxidant activity of CGM. Although CGM has been widely investigated, its protective effect against oxidative-damage to keratinocytes, as well as the relationship between CGM and autophagy, has not been investigated. The aim of this study was to assess the protective effect of CGM against H2O2-induced oxidative stress and to evaluate the autophagic features induced by CGM in human keratinocytes. The pretreatment with CGM significantly reduced apoptosis in H2O2-exposed HaCaT cells. It promoted the degradation of caspase-3, caspase-8, and caspase-9; and it induced the formation of the processed PARP. The treatment with CGM caused an increase in vesicle formation compared to control group. The level of p62 was reduced and the conversion of LC3-I to LC3-II was increased in CGM treated HaCaT cells. Also, the treatment with CGM increased cleavage of ATG5-ATG12 complex. In summary, CGM helps the cells to survive under stressful conditions by preventing apoptosis and enhancing autophagy. Besides, the present investigation provides evidence to support the antioxidant potential of CGM in vitro and opens up a new horizon for future experiments.

We reviewed 49 cases of moderate or severe pericardial effusion on which we performed pericardiocentesis and percutaneous pericardial biopsy from Jan. 1987 to Sep. 1989. Of these, 11 cases were performed percutaneous pericardial biopsy in order to diagnose confirmative. We studied clinical manifestation including physical examination, ECG, and radiology, etiology and complication of pericardiocentesis and percutaneous pericardial biopsy. The results are as belows : 1) The physical examination of pericardial effusion were neck vein engorgement(73.5%), priction rub(25.5%), and pulsus paradoxus(4%). The ECG findings were low voltage(77.6%) and electrical alternans(16.5%), and most common x-ray finding was cardiomegaly (81.6%). 2) Underlying diseases were as follows : neoplastic disease(40.8%), tuberculosis(18.4%) systemic lupus erythematosus(10.2%), hemopericardium(8.2%), chronic renal failure(6.1%), congestive heart failure(4.1%), idiopathic pericarditis(4.1%), GVHD(2.0%), pyopericardium(2.0%), rheumatic carditis(2.0%), and postpericardiotomy syndrome(2.0%), in order. 3) Special etiologic diagnosis of neoplasm were lung cancer(50%), adenocarcinoma of unknown origin(20%), Malignant lymphoma(15%), stomach cancer(5%), hepatoma(5%), and malignant thymoma(5%), in order. From the percutaneous pericardial biopsy, the authors confirmed 36% by finding two cases of malignancy and two cases of tuberculosis. On the other hand, only one case was confirmed in cytology. These result in a rather low rate of diagnostic confirm. There were 8 cases of complication : hypotension(8.2%), premature ventricular contraction(6.1%) and ventricular tachycardia (2.0%) without death cases. In percutaneous pericardial biopsy, only two cases of hypotension were found with no death case. The result obtained from the above 11 cases of percutanous pericardial biopsy is not enough to make conclusive statement concerning rate of diagnostic confirmation and complication. We expect better results by examining more cases in the future.

BACKGROUND: Laparoscopic cholecystectomy is a standard treatment for cholelithiasis and indication is continuously widened to acute and complicated cholecystitis. It has been proved to give advantages such as less postoperative pain, postoperative complications and early recovery. However, postoperative hepatic dysfunction after laparoscopic cholecystectomy has been repeatedly reported and when we evaluate postoperative hepatic dysfunction, laparoscopic surgery has been thought as one of the contributors. So authors planned this study to satisfy the growing need of reevaluation of postoperative hepatic dysfunction because we have had many achivements and improvements in knowledge and operative techniques since a while. METHODS: From January to December in 2000, 182 patients were randomly selected among who had undergone cholecystectomy in one university hospital. The numbers of each group (group OC; open, group LC; laparoscopy) were equal. Demographic data, duration of operation and level of liver enzymes (alanine transferase, alkaline phosphatase, total bilirubin and direct bilirubin) on operation day and one postoperative day were estimated by medical records. RESULTS: Mean operation time was longer in group OC than in group LC. Levels of alanine transferase, total bilirubin and direct bilirubin of postoperative one day were increased significantly in both groups. The degrees of increase of alanine transferase and bilirubin were higher in group OC than group LC in statistically significant manner. CONCLUSIONS: Laparoscopic cholecystectomy has more advantages than open cholecystectomy in many aspects.

BACKGROUND: The medical service delivery system in Korea works inefficiently and patients tend to visit tertiary hospitals by means of the emergency department (ED). Overcrowding of the ED threatens the health and life of emergency patients as a result of the inability to effectively distribute emergency medical resources in the community. To solve this problem, improvement in the medical delivery system and dispersion of patients by strengthening primary care may be helpful. In order to make policy decisions for this, it is necessary to estimate the scale of patients who can be distributed to primary care.METHODS: From January 1 to December 31, 2016, we analyzed the National Emergency Department Information System (NEDIS) data of patients who visited a tertiary ED to examine the proportion of patients eligible for primary medical care. The inclusion and exclusion criteria for primary care were made through the consensus of three physicians.RESULTS: A total of 65,061 NEDIS records were analyzed. Among them, by inclusion criteria, 29,818 cases were Korean Triage and Acuity Scale level 4 and 5, and 11,791 patients visited the ED during the day. After considering the exclusion criteria, there were 6,468 cases who may be suitable for primary medical care.CONCLUSION: Of the patients who visited the ED of tertiary hospitals, approximately 10% of them may be suitable for primary care. There should be a discussion and social consensus to reduce overcrowding in EDs and deliver better medical services.

PURPOSE: To compare birth weight between infants with a single umbilical artery (SUA) and normal infants, investigate the associated anomalies of infants with SUA and isolated SUA (no abnormality of external appearance on birth, except SUA), and determine the prognosis of infants with isolated SUA. METHODS: Live-born infants with SUA (n=59) detected by physical examination from among 15,193 live births in seven university hospitals in Korea between January 1, 2004, to August 1, 2007, were reviewed retrospectively, with 236 normal infants serving as the control group. RESULTS: A statistical difference was observed between the groups in birth weight and in vitro fertilization. The incidence of infants with SUA was 0.37%. Congenital malformations were observed in 21 infants with cardiovascular (n=15, 25.4%), gastrointestinal (n=2, 3.4%), genitourinary (n=9, 15.3%), neuromusculoskeletal (n=6, 10.2%), central nervous system (n=1, 1.7%), chromosomal (n=1, 1.7%), and other (n=3, 5.1%) abnormalities. There were 49 (83.1%) infants with isolated SUA in this study population; among them, the associated congenital malformations were cardiovascular (n=6, 12.2%) and genitourinary (n=6, 12.2%) abnormalities. Two infants with cyanotic heart disease were operated and four infants with acyanotic heart disease showed improvements without any treatment. Six infants with genitourinary abnormalities on renal ultrasound had mild hydronephrosis without further consequences. CONCLUSION: The incidence of structural abnormalities in the cardiovascular and genitourinary systems is high and the genitourinary anomalies associated with isolated SUA have relatively good prognosis.

To what extent the risks of neonatal morbidities are directly related to premature birth or to biological mechanisms of preterm birth remains uncertain. We aimed to examine the effect of exposure to amniotic fluid (AF) infection and elevated cytokine levels on the mortality and pulmonary, intestinal, and neurologic outcomes of preterm infants, and whether these associations persist after adjustment for gestational age at birth. This retrospective cohort study included 152 premature singleton infants who were born at ≤ 32 weeks. AF obtained by amniocentesis was cultured; and interleukin-6 (IL-6) and IL-8 levels in AF were determined. The primary outcome was adverse perinatal outcome defined as the presence of one or more of the followings: stillbirth, neonatal death, bronchopulmonary dysplasia, necrotizing enterocolitis, intraventricular hemorrhage, and periventricular leukomalacia. Logistic regression analysis was adjusted for gestational age at birth and other potential confounders. In bivariate analyses, elevated AF IL-6 and IL-8 levels were significantly associated with adverse perinatal outcome. These results were not changed after adjusting for potential confounders, such as low Apgar scores, mechanical ventilation, and surfactant application. However, the independent effect of elevated cytokine levels in AF disappeared when additionally adjusted for low gestational age at birth; consequently, low gestational age remained strongly associated with the risk of adverse perinatal outcome. In conclusion, elevated levels of pro-inflammatory cytokines in AF are associated with increased risk of adverse perinatal outcomes, but this risk is not independent of low gestational age at birth. Culture-proven AF infection is not associated with this risk.

OBJECTIVE: The aim of the present study was to evaluate the clinical efficiency of fluorescent in situ hybridization (FISH) in the prenatal diagnosis of chromosomal aneuploidy. METHODS: We reviewed data of 268 cases to identify women undergoing genetic amniocentesis at cytogenetic laboratory, from January 2000 to December 2002. Amniotic fluid was submitted for both rapid FISH on uncultured interphase amniocytes using a commercially available DNA probe for chromosome 13, 18, 21, X, Y and standard karyotyping on cultured metaphase amniocytes. Results from FISH and full karyotype were compared. RESULTS: There were 251 cases (84%) normal and 17 cases (16%) abnormal in FISH results. All 17 cases of trisomy 13, 18, 21 including two cases of mosaicism and sex chromosome aneuploidies which are detected by FISH were confirmed with conventional cytogenetics and there was no false positive result. Twenty two cases had karyotypically proven abnormalities that could not have been detected by the targeted FISH. CONCLUSION: Interphase FISH analysis of uncultured amniotic fluid cells has been shown to be an effective and reliable technique for rapid fetal aneuploidy screening during pregnancy as an adjunctive test to conventional cytogenetics.
