Angiomyofibroblastoma is a distinctive, hitherto uncharacterized, benign soft tissue tumor of the vulva with histology similar to an aggressive pelvic angiomyxoma. It can be distinguished from an aggressive angiomyxoma by its circumscribed borders, higher cellularity, more numerous blood vessels, the frequent presence of plump stromal cells, minimal stromal mucin, and rarity of erythrocyte extravasation. We experienced a case of angiomyofibroblastoma of the vulva occurring in a 45-year-old woman. The lesion was a well-defined but not encapsulated mass, 4.5x4.2 cm. Histologically the mass was characterized by alternating hypercellular and hypocellular edematous zones in which abundant blood vessels were irregularly distributed. Immunohistochemically, the spindled, plump spindled, and oval stromal cells were reactive for vimentin and desmin, but not for cytokeratin, or S-100 protein.

Since the epidural catheterization has been widely used for the purpose of anesthesia, diagnosis and pain control, there are various undesirable complications and hazards through the technical procedure or catheterization itself. Authors have experienced several hazards of location of the epidural catheter tip which were detected by epidurography performed the 1st. or 2nd. postoperative day with 50% Angiograffin. Hazards were as follows; 1) Single air bubble in the epidural space. 2) Inappropriate placement of the catheter tip. 3) Kinking of catheter in the epidural space. 4) Intravascular placement of the catheter.

BACKGROUND: Intracerebral hemorrhage (ICH) is associated with a considerable proportion of stroke and head injuries, but except for supportive care, there is no medical therapy available. Transplantation of human neural stem cells (NSCs) can be used to reduce behavioral deficit in experimental ischemic infarct model. However, effect of stem cell transplantation in experimental intracerebral hemorrhage (ICH) is unknown. We hypothesized that NSCs could migrate and differentiate into neurons or glial cells, and improve functional outcome in ICH. METHODS: Experimental ICH was made by intrastriatal administration of bacterial collagenase in adult rats. Animals were randomized to receive intravenously either immortalized Lac-Z positive human NSCs (5x1 06 in 500microL, n=15) or same volume of saline (n=12) on the following day. Animals were evaluated for 8 weeks after surgery with behavioral test battery. After 8 weeks, animals were sacrificed and the brains were sectioned. Transplanted NSCs were detected by X-gal histochemistry or beta-gal immunohistochemistry, and differentiation of grafted NSCs were evaluated by double labeling of GFAP, NeuN, or neurofilament. RESULTS: Transplanted NSCs migrated to the side of peri-hematomal areas, and differentiated into neurons and astrocytes. NSCs injection group showed improved performances on rotarod test after 2 weeks and on limb placing test after 5 weeks compared with control group (p<0.05) and these effect persisted up to 8 weeks. CONCLUSIONS: Intravenously injected NSCs enter rat brain with ICH, and differentiate into astrocytes or neuronal cell, which lead to functional recovery. These findings show the possibility that NSCs can be used to reduce neurological deficits in the experimental ICH.

Several studies have indicated that the addition of sodium bicarbonate and opioid to soiutions of locl anesthetics shortens the onset time,increases the intensity and prolongs the duration of neural blockade. This study was performed to compare onset times and duration of neural blockade in each groups. Eighty-two parturients scheduled for cesarean section at term under epidural anesthesia were assigned to three groups. Group 1 (n=19) received 1.5% lidocaine hydrochloride (pH 6.32+/-0.01), group 2 (n=26) received 1.5% lidocaine hydrochloride plus fentanyl 50 mcg (pH 6.27+/-0.02) and group 3 (n=37) received l.5% lidocaine hydrochloride plus fentanyl 50 mcg plus 8.4% sodium bicarbonate (sodium bicarbonate l mEq/lidocaine 10 ml)(pH 7.32+/-0.03). All groups were given 22-28 ml of local anesthetic solutions according to their height. Onsei times and duration of sensory blockade were evaluated using pin prick test at two minutes interval after epidural injection at L2, 76, T4 dermatomes. Onset timcs (time between the completion of anesthetic injection and loss of pin prick sensation at each dermatome) of sensory blockade at L2 dermatome were 3.1+/-0.2 minutes in Group 3, which were shorter than 5.0+/-0.3 minutes in Group l and 4.7+/-0.4 minutes in Group 2 (p<0.05). At T6 dermatome, onset times of sensory blockade were 6.9+/-0.6 minutes in Group 3, which were shorter than 15.4+/-1.2 minutes in Group l and 12.9+/-1.0 in Group 2 (p<0.05). At T4 dermatome, onset times of sensory blockade were 10.l+/-0.2 minutes in Group 3, which were shorter than 22.3+/-1.2 minutes in Group 1 and 18.8+/-1.1 in Group 2 (p<0.05). The duration (time between loss of pin prick sensation and complete recovery of pain at each dermatome) of sensory blockade at T4 dermatome in Group 3 were 74.0+/-3.8 min, which were longer than 52.9+/-2.4 minutes in Group 1 and 52.7+/-1.4 minutes in Group 2 (p<0.05). The duration of sensory blockade at L2 dermatome in Group 3 were 119.6+/-4.4 minutes,which were longer than 78.6+/-4.8 minutes in Group 1 and 81.6+/-2.5 minutes in Group 2 (p<0.05). The above results suggested that alkalinization of lidocaine solution is an effective way to shorten the latency and to prolong the duration of epidural block for cesarean section.

The incidence of phrenic nerve block following brachial plexus block, performed above clavicle, have varied widely. However, respiratory difficulty due to unilateral phrenic nerve block is rare complication of brachial plexus blocks, We experienced a case of symptomatic unilateral phrenic nerve block after supraclavicular approsch in thirty-four-year old woman. For brachial plexus block, 30 ml of 1.5% lidocaine and 0.2 mg of epinephrine were injected. Twenty five minutes after injection, she complained of respiratory difficulty. At recovery room, she complained sharp chest pain at apex of heart and epigastrium. We diagnosed her case as right phrenic nerve block because her right diaphragm was normal contour but was markedly displaced upward in portable chest X-ray. Respiratory difficulty was recovered 5 hours after injection and her chest pain was recovered 9 hours after injection.

The common causes of postoperative liver dysfunction during anesthesia and surgery are due to the decreased cardiac output and/or systemic blood pressure as well as poor regional distribution of hepatic blood flow. It is well known that the surgical manipulation and the kinds of operation, especially around the hepatic area, are more important factors about the hepatic blood flow than anesthetics and anesthesia techniques. We postulated that the activity of sympathetic reflex initiated by surgical manipulation could be abolished by instituting epidural block on the peripheral operative field and consequently hepatic blood flow might be improved. We randomly selected 40 patients for upper abdominal surgery and divided them into 4 groups as follows: Group 1: Halothane anesthesia (10 cases, normal liver function test (LFT); contol) Group 2: Halothane anesthesia with epidural block (10 cases, normal LFT) Group 3: Enflurane anesthesia (10 cases, abnormal LFT; control) Group 4: Enflurane anesthesia with epidural block (10 cases, abnormal LFT) Epidural block was performed just before general anesthesia with 1% lidocaine, 2 ml/segment. Mean arterial pressure (MAP) was measured before anesthesia and at 5, 10, 15, 20, 30 and 60 min during surgery. And serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT), alkaline phosphatase, total protein and albumin were measured before anesthesia and on the 1st, 3rd, 5th and 7th postoperative day. The results were as follows: 1) MAP was changed significantly at 20 min in group 2 (p < 0. 01) and at 15 min in group 4(p < 0. 05). 2) The values of postoperative LFT were changed similarly but no statistical difference between group 1 and 2. 3) The values of postoperative LFT were declined significantly (esp. SGOT and SGPT), but no statistical difference between group 3 and 4. 4) Even though the postulation is correct, the effects of epidural block combined with general anesthesia (group 2, 4) on postoperative liver function were not different statistically compared with that of general anesthesia alone (group 1, 3). It might be suggested that the amount of decreased blood flow caused by surgical manipulation would be similar with that by the epidural block. 5) Now we hope that the further evaluation will be expected about the hepatic blood flow such as direct measurement.

BACKGROUND: The present study was done to elucidate the effects of acute normovolemic hemodilution (ANH) on intrapulmonary shunt (Qs/Qt) and systemic oxygen delivery balance during one lung ventilation (OLV). METHODS: To induce one lung ventilation, an atelectasis of the right lung was produced in anesthetized mongrel dogs. In 6 dogs with OLV, ANH was produced by sequential hemodilution with hydroxyethyl starch. ANH was divided into 3 stages (ANH0: no hemodilition, ANH1: first hemodilution, ANH2: second hemodilution). Qs/Qt was measured by using blood gas analysis. Various hemodynamic parameters, oxygen delivery, and consumption were measured or calculated indirectly. RESULTS: After hemodilution, hemoglobin levels at each stage were 9.9 +/- 1.3 g/dl (ANH0), 7.0 +/- 1.0 g/dl (ANH1), and 5.2 +/- 0.7 g/dl (ANH2). The Qs/Qt of ANH2 stage increased from 25.0 11.4% of ANH0 to 35.4 9.2% (P < 0.05). Cardiac output of ANH2 increased from 2.4 +/- 0.8 ml/min of ANH0 to 3.2 +/- 0.8 ml/min (P < 0.05). Pulmonary and systemic vascular resistance measurements in ANH2 were lower than those of ANH0 (P < 0.05). The changes in pH and carbon dioxide tension and mixed venous oxygen tension by ANH were not significant in comparison with ANH0 (P > 0.05). Global oxygen delivery was markedly decreased by hemodilution in OLV (P < 0.05), whereas global oxygen consumption was maintained. CONCLUSIONS: We conclude that global oxygen delivery balance is preserved by ANH in this study. However, extreme ANH has a deleterious effect on pulmonary gas exchange, possibly through the attenuation of hypoxic pulmonary vasoconstriction during one-lung ventilation. On the basis of this study, increased cardiac output generated by ANH might be the cause of inhibition or blunting of hypoxic pulmonary vasoconstriction.

The purpose of this study was to prevent the dilutional effect of excessive absorption of irrigating solution by using furosemide intraoperatively during transurethral resection of the prostate. Thirty patients, classified as ASA ps 2 or 3, were selected randomly and divided them into two groups as follows: Group l(N=15); Not-administrated furosemide(control group) Group 2(N=15); Administrated furosemide(Experimental group) All patients were premedicated with hydroxyzine(1 mg/kg, IM) and were performed continuous epidural anesthesia with 2/ lidocaine(1-1.5 mg/segment). 5% D-sorbitols were used for irrigating solution, and Hartmans solutions were given for maintenance fluid. And fixed the irrigating container to 60 cm in height from symphysis pubis. With the starting of operation, 20 mg furosemide was administrated to experimental group. The blood samples for serum Na+, K+, glucose and BUN were obtained at preoperation, 10 min, 20 min, 30 min after the stating of operation and immediate postoperative period, and serum osmolality and effective osmolality were calculated. The results were as follows: l) The values of sodium concentration of control group were decreased significantly at 10 min, 20 min, 30 min after the starting of operation and immediate postoperative period as compared with the preoperative value(p<0.05). But those of experimental group were not changed significantly. 2) The values of serum osmolality and effective osmolality were decreased significantly at 30 min after the starting of operation and immediate postoperative period as compared with the preoperative value(p<0.05). But those of experimenta1 group were not changed significantly. These results show that the dilutional effect of excessive absorption of irrigating solution might be prevented by using furosemide intraopertively. So we would like to recommend the use of furosemide during TURP, especially in patients with congestive heart failure or renal failure.

Subclavian venous catheterization is common technique for a variety of purposes, but this procedure is associated with complications that include damage to the lung, pleura, thoracic duct, nerve and subclavian artery. We recently encountered a case of the tracheal puncture and endotracheal cuff perforation during the subclavian catheterization in a 67-year-old female who was scheduled for tracheal reconstruction. Tidal volume was escaping from around the endotracheal tube during the subclavian catheterization, however, repeated inflation of the cuff failed to maintain the necessary cuff pressure to seal the trachea. After the operation, by using the fiberoptic bronchoscope and injecting dye into the cuff, we confirmed the site of tracheal puncture and endotracheal cuff perforation which caused by the introducer needle of the central venous kit. We suggest that tracheal puncture and endotracheal cuff perforation be added to the list of complication of subclavian catheterization. This complication should be suspected whenever the cuff pressure cannot be maintained during or after an subclavian catheterization.
