BACKGROUND: Elderly patients with underlying cardiovascular or respiratory diseases are more susceptible to anesthesiologic risks or serious complications following laparoscopic operations. We evaluated the safety of laparoscopic radical nephrectomy in elderly patients to compensate for the lack of Korean data on the subject in the field of urology. METHODS: From March 2003 and March 2009, 73 patients with localized renal cell cancer underwent laparoscopic radical nephrectomy. They were divided into two groups according to age; 75 years or older (elderly group, n=21) and under 75 years (young group, n=52). Operative parameters as well as oncological outcomes were evaluated. RESULTS: The mean age was 77.7+/-2.5 years for the elderly group and 55.9+/-10.5 years for the young group. No significant differences existed between the groups in terms of mean operative time, intraoperative blood loss, complications, and hospital stay. However, American Society of Anesthesiologists (ASA) score, co-morbidities (p<0.05), and rate of transfusion (p<0.05) were significantly higher in the elderly group. In overall analyses, we conclude that in elderly patients undergoing laparoscopic radical nephrectomy, close monitoring of hemoglobin level as well as intraoperative transfusion for maintenance of hemoglobin level at 10 mg/L or higher is necessary in elderly patients to achieve adequate circulation. CONCLUSION: Laparoscopic radical nephrectomy can be considered a safe and effective procedure for most elderly patients.

BACKGROUND: Circadian variations in the absorption, distribution, protein binding, elimination and metabolism of drugs account for many of the administration-time-dependent differences in their pharmacokinetics. The aim of this study is to determine whether the time of intrathecal injection influences spinal anesthesia. METHODS: Ninety patients scheduled for orthopedic surgery were randomly assigned to three groups. Each group received spinal anesthesia with 0.5% bupivacaine 10 mg at different times; group AM (8 am to 12:00), group Noon (12:00 to 4:00 pm) and group PM (4:00 pm to 8:00 pm). Sensory and motor blockade were assessed by pinprick and a four-point modified Bromage scale. Time to first postoperative analgesic requirement and side effects such as hypotension, bradycardia, nausea, and shivering were recorded. RESULTS: No significant differences were found among the three groups in peak sensory blockade, duration of motor block to Bromage 1 or side effects, but time to first postoperative analgesic requirement (P = 0.008), and recovery time of S1 sensation to pinprick were significantly prolonged in group Noon compared with the other groups (P = 0.03). CONCLUSIONS: The tine of administration of spinal local anesthetics influences the duration of local anesthesia.

During inflammation of the colon, cells of the gut mucosa express numerous inflammatory mediators including interleukin-8 (IL-8), tumor necrosis factor-alpha (TNF-alpha), and interleukin-1beta(IL-1beta). These cytokines have been implicated as contributing factors in the inflammatory process, which may result in colitis during inflammatory bowel disease (IBD). Gliotoxin is a fungal metabolite of an epipolythiodioxopiperazine analogue with immunosup-pressive properties in vivo and in vitro, but the effects of gliotoxin on IBD have not been largely evaluated. Therefore, this study evaluated the potential of gliotoxin to protect against TNBS-induced colitis. One microgram of gliotoxin in 100microliter of vehicle was intra-rectally administered into mice exhibiting trinitrobenzene sulfonic acid (TNBS)-induced colitis. IL-8 secretion was measured using an enzyme-linked immu-nosorbent assay (ELISA), myeloperoxidase (MPO) activity was evaluated spectrophotometically, and IkappaB degradation was analyzed on Western blots. Gliotoxin treatment of mice bearing TNBS-induced colitis improved macro-and micro-pathological findings and dramatically decreased MPO activity, a marker of leukocyte infiltration. Furthermore, gliotoxin decreased IkappaB degradation and IL-8 induction caused by TNF-alpha or IL-1beta in HT-29 cells. These findings suggest that gliotoxin partially protects against TNBS-induced colitis through the sup-pression of IL-8 induction and IkappaB degradation by inflammatory mediators such as TNF-alpha or IL-1beta.

OBJECTIVES: The purpose of this study was to determine the association between the bone mineral density (BMD) and severity of spinal osteoarthritis (spondylosis) in osteoporotic spinal compression fracture. METHODS: Fifty six patients were evaluated 66 cases had an osteoporotic thoracolumbar compression fracture between January 2008 and June 2010. The average patient age was 76.2 years (M/F : 8/48). Age and body mass index (BMI, kg/m2) were measured, and the BMD was performed using peripheral quantitative computed tomography (pQCT). Simple thoracolumbar (T-L) spine lateral radiography was evaluated for three criteria: presence of osteophytes, disc space narrowing and vertebral body sclerosis. The findings were graded 0 to 3 and analyzed statistically for a correlation with the BMD and fractured vertebrae. RESULTS: Acute compression fractures comprised of 15 cases and the most common site of acute fractures with old fractures was lumbar spine (L1; 30 cases, 45.4%). The average of BMI was 23.32 and BMD (T-score) was -4.47. Pearson's rho showed a positive association between the weight, height and the BMD (P < 0.01). In terms of the BMD versus spondylosis, there was a positive association with high score in the high order cortical bone. Compression fractures occurrence rate in the absent and present of spondylosis was 74.3% and 22.4%, and 69% occur in the spinal segmental with no bony spur with chi-square test (P < 0.01). CONCLUSION: In the present of spondylosis was high score of cortical BMD and low rate of compression fracture. Spondylosis could be one of a factor of the occurrence in acute and adjacent compression fracture after old fractures.

The risk of deep vein thrombosis (DVT) is well studied for some orthopedic surgery. However, the incidence of postoperative DVT is less well-defined in patients who have spinal surgery. In addition, there is insufficient evidence to suggest that screening patients before spinal surgery and to use of prophylactic method such as anticoagulants, compression stockings, and pneumatic compression device. We experienced a 78-year-old female patient of DVT after fusion operation with pedicular screws in T12 osteoporotic compression fracture. As risk of DVT after major spinal surgery is fairly low, it seems reasonable to consider prophylactic management after spinal surgery in old aged patients with difficult ambulation.

Anti-M is detected at room temperature and is often found in the sera of people who have never been exposed to human red cells. In a few cases, anti-M can be detected at 37 degrees C or at the antiglobulin phase, and these antibodies can cause hemolytic diseases in newborn or hemolytic transfusion reactions. Some examples of anti-M demonstrate stronger agglutination at low pH (pH 6.5), and when they react with the red blood cells of the MM type (dosage effect). An unexpected antibody test was carried out for the routine screening of donated blood and two cases that reacted to all panel cells at 5 degrees C were found, which indicated anti-M. We repeated the unexpected antibody identification test at pH 6.5 and confirmed the presence of anti-M. The reduction of the test system pH is a useful and simple method for detecting some cases of anti-M.

PURPOSE: Ketamine may decrease core-to-peripheral redistribution of heat through direct central sympathetic stimulation and inhibition of norepinephrine uptake into postganglionic sympathetic nerve endings. The purpose of this study was to evaluate the efficacy of epidural ketamine in preventing shivering during transurethral resection of the prostate (TURP) under epidural anesthesia. MATERIALS AND METHODS: Ninety-three male patients scheduled for TURP under epidural anesthesia were enrolled in this study. Patients were randomized into one of three groups. Group 1 consisted of 31 patients who received epidural 0.75% ropivacaine, group 2 consisted of 32 patients who received epidural ketamine (0.2 mg/kg) in addition to 0.75% ropivacaine, and group 3 consisted of 30 patients who received epidural ketamine (0.4 mg/kg) in addition to 0.75% ropivacaine. Shivering and side effects such as hypotension, bradycardia, nausea, and hallucination were recorded during the anesthesia and for 2 hours while in the postanesthetic recovery room. RESULTS: Shivering was statistically more frequent in group 1 than in the other groups. The incidence of sedation was significantly higher in group 3 than in the other groups. The incidences of side effects such as hypotension, bradycardia, and nausea were significantly higher in group 1 than in the other groups. CONCLUSIONS: In this study, epidural ketamine 0.2 mg/kg and 0.4 mg/kg was shown to have a lower incidence of shivering and other side effects except sedation. In patients who undergo TURP under epidural anesthesia, the prophylactic use of low-dose epidural ketamine would be helpful in preventing any adverse effects, including shivering.

Small osteophytes are frequently encountered in the foot and ankle, and not to be confused with true osteochondromas, which are relatively uncommon in this region. Osteochondromas are the most common benign osseous neoplasm, occurs in the metaphysis of the long bone. It is rarely found in bones of the foot. Treatment of the osteochondroma is usually conservative, unless symptoms usually pain, are progressive rapid growth, and malignant transformation is suspected. We experienced a rare case of hallux rigidus with osteochondroma of the hallucal proximal phalanx which cause pain and corn of the plantar.

We recently encountered an interesting case of acute inferior ST segment elevation myocardial infarction (STEMI). This patient had a rare anatomic variation, single coronary artery. The right coronary artery originate from the left circumflex proper artery, not from aorta, was totally obstructed with thrombi. Though it took more time to figure out the patient's coronary anatomy and the culprit lesion, we successfully performed primary percutaneous coronary intervention within the guideline-recommended time period. We performed left coronary angiography at the beginning. This strategy could be helpful in determining the culprit lesion and preventing unnecessary procedural delay in acute inferior STEMI.
