BACKGROUND: Various kinds of methods had been tried to reduce pain on injection of propofol. In this study, the effect of lidocaine pretreatment and that of temperature controlled injections were compared and evaluated its clinical utility. METHODS: One hundred and twenty patients were randomly allocated into 4 groups after permission. Room temperature propofol was used as induction agent in group P,. In group C, cooling (4 degrees C) propofol was used and warming propofol (37 degrees C) in group H. And room temperature propofol following lidocaine (1 mg/kg) was used in group L. Injection dosage of propofol was 2 mg/kg and injection speed was 2 ml/sec in all groups. In each patients, pain score and visual analog scale were measured and tested by ANOVA or Kruskal-Wallis test. RESULTS: There were no statistical significant difference in pain score among the 4 groups. But in visual analog scale analysis, group L markedly reduced values than the other groups by statistically significant manner (in Duncan grouping). CONCLUSION: The alleviating effect of lidocaine pretreatment on painful injection was better than that of changing temperature of propofol itself. More over effectiveness, in view of simplicity, we recommend lidocaine pretreatment.

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.

BACKGROUNDS: Pancreaticoduodenectomy has been applied to diseases of periampullary region since 1935 by Whipple and associates, but this procedure is so complexed that associated with high morbidity and mortality. In the treatment of periampullary cancer, curative surgical resection only promises the possibilities of cure, because other methods of treatment including chemotherapy and radiation therapy have been of little or no benefit to improve the survival rate. METHODS: We performed the clinical analysis on 123 cases of pancreaticoduodenectomies at the department of Surgery, Chonnam University Hospital, during the past 11 years from June 1986 to May 1997 to assess the associated factors with postoperative complications and the survival rate. RESULTS: Among 123 cases, 104 cases(84.6%) were malignant tumor of periampullary region, 16 cases were benign lesion, and 3 cases were type IV pancreatic injury. Pancreaticoduodenectomy was performed in 115 cases, pylorus-preserving pancreaticoduodenectomy in 4 cases, total pancreatectomy in 2 cases and extended pancreaticoduodenectomy in 2 cases. Postoperative complications were developed in 28 cases(22.8%) and the major cause of postoperative complication was the anastomotic leakage, especially in the pancreatico-jejunostomy site. The overall operative and hospital mortality rate was 7.3%. Preoperative percutaneous transhepatic biliary drainage(PTBD) and the serum level of albumin and bilirubin were not related to the development of postoperative complications. Factors affecting survival after resection of malignant tumor were the size of tumor, presence of lymph node metastasis and tumor infiltration to adjacent tissue, but the level of CEA, alphaFP, and CA 19-9 and tumor differentiation were not related to the survival rate statistically. CONCLUSION: Optimal preoperative preparation of the patient and a meticulous and standarized operative technique are mandatory to minimize the operative morbidity and mortality after pancreaticoduodenectomy. In the treatment of periampullary cancer, radical surgical resection is recommended for long-term survival, as well as the development of other treatment modalities to prevent the postoperative recurrence.

There have been a few reports on deep vein thrombosis (DVT) associated with compression of the left common iliac vein by the right common iliac artery, referred to as May-Thurner syndrome (MTS). However, there have been no reports on DVT associated with MTS in amyotrophic lateral sclerosis (ALS) patients exhibiting similar clinical features to paraplegic spinal cord injury patients. We hereby report a case of DVT associated with MTS in an ALS patient, who was treated successfully.

The neurotoxic effects of inorganic lead, a common environmental toxic substance, include peripheral neuropathy in adults and encephalopathy in children. Behavioral changes including hyperactivity, short attention span, easy distractibility and impulsiveness have also been noted in patients with chronic lead exposure in childhood. The level of norepinephrine in brain may relate to hyperactivity and chronic lead exposure. The purpose of this study was to determine the effect of inorganic lead (PbCl(2)) administration in neonatal rats using immunocytochemical and electron microscopical analysis of norepinephrinergic neurons of the locus ceruleus. Lead chloride were dissolved in distilled water at the concentration of 0.05%, 0.1% and 0.2% and the solution was administered orally via drinking water. After 4, 8 or 12 weeks of continuous administration, all rats were sacrificed and the brain was processed and immunostained with antibody against tyrosine hydroxylase, a rate limiting enzyme of norepinephrine synthesis antibody. The number of tyrosine hydroxylase immunostained cell bodies in locus ceruleus was estimated. Densitometric analysis of tyrosine hydroxylase immunoreactive profiles in electron microscopic photographs were done by using image analyzer. The number of tyrosine hydroxylase immunoreactive neurons in the locus ceruleus had increased statistically after lead administration. Density of tyrosine hydroxylase immunoreactive profiles in the electron microscopy had also increased. Degenerative changes, such as intra-axonal vacuolar space formation, were found within tyrosine hydroxylase immunoreactive axons. Somewhat widened intercellular spaces and retracted processes were also found in the region of the locus ceruleus. Increased tyrosine hydroxylase immunoreactivity may correlate with hyperreactivity of lead intoxicated children. Degenerative changes may be responsible for the short attention span, easy distractibility and impulsiveness observed in case of mild lead poisoning.

Subchondral insufficiency fracture (SIF) of the femoral head occurs in the elderly and recipients of organ transplantation. Osteoporosis and deficient lateral coverage of the acetabulum are known risk factors for SIF. There has been no study about relation between spinopelvic alignment and anterior acetabular coverage with SIF. We therefore asked whether a decrease of lumbar lordosis and a deficiency in the anterior acetabular coverage are risk factors. We investigated 37 patients with SIF. There were 33 women and 4 men, and their mean age was 71.5 years (59-85 years). These 37 patients were matched with 37 controls for gender, age, height, weight, body mass index and bone mineral density. We compared the lumbar lordosis, pelvic incidence, pelvic tilt, sacral slope, acetabular index, acetabular roof angle, acetabular head index, anterior center-edge angle and lateral center-edge angle. Lumbar lordosis, pelvic tilt, sacral slope, lateral center edge angle, anterior center edge angle, acetabular index and acetabular head index were significantly different between SIF group and control group. Lumbar lordosis (OR = 1.11), lateral center edge angle (OR = 1.30) and anterior center edge angle (OR = 1.27) had significant associations in multivariate analysis. Decreased lumbar lordosis and deficient anterior coverage of the acetabulum are risk factors for SIF as well as decreased lateral coverage of the acetabulum.

OBJECTIVES: Gastrectomy with lymph node dissec tion is the standard treatment for early gastric can cer(EGC). However, patients who have high risks demand modifications in surgical treatment for EGC. Recently, endoscopic mucosal resection(EMR) has become accepted in many institutions as a treatment for cancerous mucosal lesions of the stomach. Thus we investigated the efficacy and safety of EMR prospectively in the patients with EGC who have high risks in surgery and those with premalignant lesions. METHOD: Twenty-five patients were treated with EMR, thirteen were EGC and twelve were premalignant lesions such as tubular adenoma, severe dysplasia. We used standard snare method and endoscopic mucosal resection using a band ligation kits(EMRL). RESULTS: The complete resection rate at the first step of EMR was 100%(12/12) in premalignant lesions, 76.9%(10/13) in EGC. Of three EGC resected incomple tely at the first step, one patient was treated by surgery and two patients underwent the third step of EMR. The final complete resection rate was 92%(23/25) and it was 100%(12/12) in the premalignant lesions, 84.6%(11/13) in EGC. The final complete resection rate in according to the methods was 100%(5/5) by standard snare method, 75%(6/8) by EMRL. As pathologic results, all cases of EGC were limited to the mucosa. No serious complications such as perforation, major bleeding were encountered. CONCLUSION: We consider that EMR is effective and safe in treatment of the patients with EGC who have high risks in surgery and those with premalignant lesions.

BACKGROUND: This study analysed patterns of requests for repeated blood cultures and the microorganisms isolated in follow-up cultures. METHODS: The frequencies and intervals of repeated blood cultures performed during January and February of 2010 at seven university-affiliated hospitals in Korea were evaluated. Results of microbiological cultures at follow-up were analysed with respect to pathogen replication, immune clearance, appearance of new pathogens, and skin contaminants. RESULTS: Among 3,072 patients who received repeated blood cultures, the average number of requests was 3.2. Of the 5,241 follow-up blood culture events recorded, durations of 1, 2, and 3 days between cultures were identified for 23.1%, 21.4%, and 15.0% of events, respectively. Relative to each initial culture, persistent pathogen growth in subsequent culture(s) accounted for 2.3% of events, whereas immune clearance was confirmed in 8.5% of events. Previously undetected pathogens were isolated in 5.2% of the follow-up cultures, the majority of which grew after an interval of six days. Skin contaminants were detected in 7.6% of the repeated cultures, and 76.1% of the follow-ups displayed no growth of microorganisms. CONCLUSION: The most common numbers of repeat culture requests were two and three, and these were typically performed within three days of the initial culture. Among the follow-up cultures, new pathogens were identified in 5.2%, and the majority of this group likely presented for follow-up during a new disease episode.

Arteriovenous malformations (AVM) are an unusual cause of gastrointestinal (GI) bleeding. But most GI AVM can occur with GI bleeding. When conventional diagnostic studies have failed to reveal the source of GI bleeding, AVM have been one of the most common causes. But the incidence of AVM presented as bleeding of a gastric submucosal tumor is very low. A case of gastric submucosal tumor was experienced and reported as an AVM. This case is herein discussed with review of corresponding literature.

Spinal dural arteriovenous fistula is a rare vascular lesion of the spinal cord associated with progressive myelopathy. Symptoms include progressive gait dysfunction, weakness, sensory loss, and bowel and bladder dysfunction. Because these symptoms overlap with other common causes of myelopathy and the disease is rare, spinal dural arteriovenous fistula is often not suspected and the time to diagnosis is long. We report the case of a 60-year-old woman who presented with progressive lower limb weakness and gait disturbance diagnosed as spinal dural arteriovenous fistula involving a fractured L1 vertebral body.
