BACKGROUND: Hemodynamic derangement during off-pump coronary artery bypass surgery (OPCAB) is mainly attributed to impaired filling and diastolic dysfunction. An elevated ratio of the mitral velocity to the early-diastolic velocity of the mitral annulus (E/e' > 15) is a relatively new indicator of diastolic function, and this was reported to be associated with impaired hemodynamics during OPCAB. We investigated the efficacy of milrinone on the perioperative hemodynamics and short term outcomes of patients with an E/e' > 15 and who underwent OPCAB. METHODS: The patients were randomly allocated into either group C (control, n = 31) or group M (n = 31) and they were treated with the same amount of either normal saline or milrinone (0.5 microg/kg/min) without bolus loading after completion of internal mammary artery harvest until the end of operation. Hemodynamic measurements were recorded after the induction of anesthesia (T1), 5 min after starting each distal anastomosis of the left anterior descending artery (T2), left circumflex artery (T3) and right coronary artery (T4), and 5 min after sternum closure (T5). RESULTS: The mixed venous oxygen saturation (SvO2) was lower through T2-T4 compared to the baseline value in both groups, while the degree of the decrease was significantly less in group M than that in group C. The other hemodynamic variables, the operative data and the postoperative outcomes were similar between the two groups. CONCLUSIONS: Intraoperative infusion of milrinone did not significantly improve the perioperative hemodynamics and the subsequent short term outcomes for the patients with preexisting diastolic dysfunction as represented by an elevated E/e' value, although it reduced the degree of decrease of the SvO2 during OPCAB.

BACKGROUND: This study investigated the effect of type of surgery on consumption of propofol and remifentanil and recovery index. METHODS: Fifty female patients (ASA physical status 1, 2) scheduled for thyroidectomy (Group I) or mastectomy (Group II) received total intravenous anesthesia (TIVA) with propofol and remifentanil. The anesthesia was maintained with target-controlled infusion (TCI) of propofol and remifentanil under bispectral index (BIS) monitoring. The effect site concentration of propofol was controlled for maintaining BIS values within the range of 45-50. The effect site concentration of remifentanil was controlled for maintaining blood pressure and heart rate within 20% of baseline values. Blood pressure, heart rate, BIS, effect site concentration of propofol and remifentanil were measured before induction, during induction, at the beginning of operation, at the end of operation, and during recovery. The time from discontinuation of propofol to eye opening and regaining of orientation, total amount of propofol and remifentanil used, and the amount of drug per body weight kilogram per hour were investigated. RESULTS: There were no significant differences between Group I and II on the amount of remifentanil used. Although the amount of propofol consumed per body weight kilogram per hour was larger in Group II, there were no significant differences of recovery index between Group I and II. CONCLUSIONS: There were no significant differences in the amount of propofol and remifentanil consumed and recovery index in thyroidectomy and mastectomy under TIVA. The larger amount of propofol consumed per body weight per hour in Group II was thought as a result of shorter operation time than Group I.

The purpose of this paper is to review the colonoscopic fingings of twenty two patients with colonic tuberculosis which were diagnosed by colonoscopic finding, histopathology, and follow-up observation after antituberculosis chemotherapy at Pusan National University Hospital from January 1992 to December 1994. The results were as follows: 1) The male to female ratio was 1: 1.2, and the average age of the patients was 39.4 years with a slight predominance in women. The age of peak incidence was the 4th decade 40.9%). 2) Abdominal pain(95%), diarrhea(63%), and weight loss(50%) were the most common clinical findings. Others were constipation, melena, and palpable abdominal mass. The location of the pain was right lower abdomen, epigastrium, central abdomen, and left lower abdomen in decreasing order. 3) Hematologic findings showed decrease in hemoglobin level, increase in ESR, and positive CRP(61.5%). The white blood cell counts were mostly normal. 4) The stool examination showed positive occult blood in 7 cases among 18 cases (38.9%). Acid-fast bacteria was observed in stool of one case. 5) On colonoscopy, the lesion sites were ileoeecal valve(75%), ascending colon(72.7 %), terminal ileum(52.6%), cecum(42.9%), transverse colon(31.8%), descending colon (27.3%), sigmoid colon(9%), and rectum(9%) in decreasing order of frequency. Most of them involved ileocecal area. 6) On colonoscopy, the shape of ulcer revealed circular(41%), fusion(36%), and irregular pattern(18%). It found skipped area in 9 cases, pseudopolyp in 8 cases, patency of ileocecal valve in 5 cases, and severe deformity of ileocecal valve in 6 cases. 7) Microscopic finding of biopsy specimens revealed noncaseating granulomatous inflammation in 12 cases, and nonspecific ulcerative inflammation in 10 cases. In conclusion the diagnostic yield may be greatly enhanced by obtaining multiple target biopsies frorn tbe deep portion of the ulcer bed and margins. Judged from the colonoscopic finding and clinical improvement after antituberculosis chemotherapy, more accurate diagnosis can be acquired.

OBJECTIVE: The aim of this study was to evaluate and compare neonatal outcome of premature twins conceived by in vitro fertilization (IVF) to those of naturally conceived. METHODS: We retrospectively analyzed neonatal outcome of sixty pairs of premature twins conceived by IVF (IVF twin group) and 34 pairs that naturally conceived (natural twin group). Maternal and obstetric characteristics were also compared. All were born before 35 weeks of gestation between January 2000 and December 2004 at Pochon-Cha Hospital and admitted to neonatal intensive care unit. Student t-test and chi-square test were used for statistical analysis. RESULTS: For obstetrical characteristics, maternal age and rates of nulliparous were sibnificanty twin group. But, other parameters (preterm labor, premature rupture of membranes, pregnancy-induced hypertension, gestational diabetes mellitus) were similar between two groups. For neonatal outcome, gestational age, duration of hospital stay, Apgar score, neonatal mortality and morbidity were reviewed. All parameters were no significant differences in IVF twin group compare to natural twin group CONCLUSIONS: In our study, IVF twin group had no significant differences in obstetric characteristics (except for maternal age and parity) and neonatal outcome compare to natural twin group.

The prediction of functional outcome in patients with acute cerebral infarction depends on many factors. Various techniques have been applied to predict severity and outcome after cerebral infarction. Neuron-specific enolase (NSE) is a component of a specific brain enzyme and a useful marker of brain injury. We evaluated the relation between initial serum NSE level and short- and long-term clinical outcome in 59 patients with acute cerebral infarction and in 38 age-matched healthy controls. Serum NSE levels were determined in patients with carotid artery (CA) territory cerebral infarction within 24 hours of onset. Brain MRI was performed four to seven days after stroke. Patients were divided into two groups: large CA territory infarction with a lesion extending cortex (cortex group), and small subcortical CA territory infarction (subcortical group) with a lesion confined to the subcortical white matter. We compared the initial serum NSE levels of the two groups. National Institute of Health Stroke Scale (NIHSS) was determined at admission and seven days after onset and the modified Rankin's scale was used at the 3 months follow-up after onset. Serum NSE levels were significantly elevated in patients with acute cerebral infarction compared with the normal controls (13.88 +/- 5.47 ng/dl vs. 8.15 +/- 1.53 ng/dl, p < 0.05). The initial ( < 24 h) serum NSE level was higher in the cortical group than in the subcortical group (16.68 +/- 5.70 ng/dl vs. 10.98 +/- 3.34 ng/dl, p < 0.05). NIHSS on admission and on the 7th day correlated with the initial serum NSE level (p < 0.05), as were more severe functional outcomes, as determined 3 months after onset (p < 0.05). This study shows that initial serum NSE level may be a useful marker for severity in acute ischemic stroke, and that it may be well correlated with short-term and long-term functional outcomes.

Glycogen storage disease type V (GSD-V) is the most common disorder of muscle glycogenosis with characteristic clinical and laboratory findings. A 32-yr-old woman complained of exercise intolerance and myoglobulinuria since early adolescence. She reported several episodes of second-wind phenomenon. Physical examination did not show any neurological abnormality, including fixed muscle weakness or atrophy. Serum creatine kinase level was 1,161 IU/L at rest. The result of the non-ischemic forearm exercise test was compatible with GSD-V. Mutation analysis identified the compound heterozygous mutations of the PYGM, p.D510fs and p.F710del, which has not yet been reported in Korea. The present case recognizes that detail clinical and laboratory analysis is the first step in the diagnosis of GSD-V.

PURPOSE: To review the 5-year outcomes of our modified mandibulotomy technique. Retrospective review of a tertiary level oral cancer center. MATERIALS AND METHODS: During a 5-year period, 30 patients who had a uniform surgical technique consisting of a lower lip-splitting, modified stair-step osteotomy with thin saw blade and osteotome after plate-precontouring and combination fixation with monocortical osteosynthesis (miniplate) and bicortical osteosynthesis (maxiplate and bicortical screws), with at least 14 months postoperative follow-up, were selected and reviewed retrospectively. RESULTS: There were 8 women and 22 men with an average age of 56.5 years. All the patients involved malignancies were squamous cell carcinoma. The main primary sites of the those who underwent a mandibulotomy were the tonsil, the base of tongue, the oral tongue, the retromolar pad area, and others. Others included buccal cheek, floor of mouth, and soft palate. 23 patients received postoperative radiation therapy, and among whom 8 patients also received chemotherapy. Total four (13%) mandibulotomy-related complications occurred, only two (6.7%) requiring additional operation under general anesthesia. CONCLUSION: Our modified mandibulotomy meets the criteria for an ideal mandibulotomy technique relatively well because it requires no intermaxillary fixation, can precise preserve the occlusion in a precise way, allows early function, requires no secondary procedures, and has few complications.

Hepatocellular carcinoma (HCC) with portal vein invasion has a poor prognosis. Treatments such as transarterial chemoembolization (TACE), radiation therapy (RT), sorafenib are done as a first line treatment. But in case of incomplete response to first line treatment, there's no established guideline about salvage treatment. We present a 47 year-old male who was diagnosed as HCC with portal vein invasion. He was treated with RT and repeated TACE, but remnant viable tumor was observed. Surgical resection was performed as a salvage treatment, and HCC was completely removed. He has been followed up over 3 years, but there was no recurrence.

PURPOSE: The purpose of this study is to define the geographic patterns of partial avascular necrosis (AVN) of the talar body and to determine whether there were any predictors of both the location and occurrence of partial AVN. MATERIALS AND METHODS: Nineteen patients with fracture of the talar neck treated by open reduction and internal fixation and followed up for more than 1 year were analyzed. The radiographs were examined 6 to 8 weeks after the operation for Hawkins sign and if it was not observed, magnetic resonance scans were performed. The three-dimensional analysis was performed using Mimics 17.0 (Materialise). The incidence of collapse and time to operative intervention was recorded. RESULTS: Partial AVN of the talar body was observed in six out of 19 patients. The avascular segment of the talar body was located predominantly in the anterolateral portion. The average volume of the avascular segment was 289 mm3, and it occupied 1% of total volume of the talus, and 10% of the talar dome. Collapse occurred in one patient in the area of the avascular process. There were no observable trends with regard to Hawkins classification, incidence of collapse, or time to operative intervention to the location of the avascular segment. CONCLUSION: Partial AVN can occur after fracture of the talar neck. The predominant location of the avascular segment was the anterolateral portion of the talar body. This information may be helpful to understanding the process of avascular necrosis of the talar body.
