Bowens disease is generally regarded as a premalignant dermatosis. If untreated, 3% to 5% of patients may develop squamous cell carcinoma. However, sebaciou carcinoma arising from Bowens disease is very rare. We presented a case of quarnous cell carcinoma and sebaceous circ s disease in a 68 year-old male. He had multiple bowenoid skin lesi nsties. A bean-sized nodule as developed on the bowenoid lesion of the he had a large yellow crust.ed exudative tumor on the Rt. thigh. We took a biopsy specimen of these three discrete lesions. The nu lipid stain of frozen section revealed Bowens disease, squarnous concllnoma arising from Bowen on the trunk and extremi Rt. lower abdomen. Almost of routine histology and carcinoma, and sebaceous carcinoma, respectively.

In pili torti, the affected Eair shaft is flattened and twisted through 180 degrees on its own axis. The involved hairs are dry, thin, brittle, and break off easily. Congenital pili torti may occur as an isolated phenomenon or may occur in association with other abnormalities. Acquired pili torti is usually associated with some sort of scarring process in the scalp itself. We present a case of congnital pili torti without any other abnormalities in a 14 year-old female. The pedigree of her fariiily was consistent with the inheritance of congenital pili torti as an autosomal dominant trait.

BACKGROUND: Morphine has a direct action on morphine receptors in the brain and spinal cord. Intrathecally administered L-NAME, a nitric oxide synthase inhibitor, is known to have an antinociceptive effect on formalin-induced pain in animal studies. Efficacy of intrathecally administered ketorolac, a cyclooxygenase inhibitor, is somewhat controversial. The interactions of intrathecally administered morphine, ketorolac and L-NAME on formalin-induced nociception was studied. METHODS: Male Sprague-Dawley rats were implanted with chronic lumbar intrathecal catheters and were tested for paw flinch by a formalin injection. Drugs were intrathecally administered 15 min before the formalin injection, and biphasic painful behaviors were observed. We obtained the ED50 for each agent (ketorolac, L-NAME and morphine). ED50 fractions (1, 1/2 and 1/4) of drug combinations of L-NAME-ketorolac, morphine-L-NAME and ketorolac-morphine were administered. The ED50 of each combined drug was established and isobolographic analysis of the drug interactions was carried out. RESULTS: Intrathecal administration of ketorolac, L-NAME and morphine produced a dose-dependent suppression of pain behaviors in phase 2. ED50 values were 297.04micro gram for ketorolac, 207.46micro gram for L-NAME and 0.17micro gram for morphine in phase 2. Isobolographic analysis showed that the combination of intrathecal morphine and L-NAME synergistically reduced pain behaviors in phase 2. CONCLUSIONS: Intrathecally administered morphine, L-NAME and ketorolac produced a dose-dependent decrease in the number of paw flinches in both phase 1 and phase 2 on the formalin test. Morphine with L-NAME showed synergistic analgesic effects on formalin-induced pain in phase 2.

BACKGROUND: The reversal of neuromuscular blocker might be accelerated if the anticholinesterase was administered in divided doses. This study has been conducted to evaluate the correct ratio of divided doses of neostigmine for the rapid recovery in the rabbits after pancuronium when the profound relaxation(PTC=0) was confirmed. METHODS: Rabbits(n=60) were randomly allocated to 6 groups. After pancuronium 0.2 mg/kg intravenously, spontaneous recovery was evaluated in group 1. When the profound relaxation(PTC=O) was confirmed at 5 min. after pancuronium, neostigmine 50 ug/kg was injected as a bolus in group 2. At that time, neostigmine was given at 10 ug/kg followed by 40 ug/kg 3 min. later in group 3. At that time, neostigmine was given at 20 ug/kg followed by 30 ug/kg 3 min. later in group 4. At that time, neostigmine was given at 30 ug/kg followed by 20 ug/kg 3 min. later in group 5. At that time, neostigmine was given at 40 ug/kg followed by 10 ug/kg 3 min. later in group 6. RESULTS: The mean time from injection of pancuronium to 95% recovery was 99.3 min. in group 1, 59.8 min. in group 2, 53.2 min. in group 3, 51.5 min. in group 4, 50.8 min. in group 5 and 41.1 min. in group 6. The recovery index was significantly reduced in group 6(p<0.05). CONCLUSIONS: We conclude that the recovery time is reduced when neostigmine is administered in divided doses: a larger priming dose followed by a smaller bolus at profound relaxation.

Sodium nitroprusside(SNP) is used to induce hypotension for a wide variety of indica- tions. Ordinarily, blood pressure responds sensitively to infusion of SNP in low doses, but occasioally resistance is seen, and actual tachyphylaxis during SNP infusion has been reported. To investigste the continuous infusion rates of SNP, we retrospectively reviewed 144 cases of spinal fusion operations which had been performed under deliberate hypotensive anesthesia (mean arterial pressure at 50-60 mmHg). To produce deliberate hypotension, The mean dose of SNP was 17.16 mg, the mean infusion time 283.85 minutes, and the average infusion rates 1.05 ug/kg/min. Patients who received csptopril required less SNP than untreated patients(0.95 vs 1.23 ug /kg/min., p<0.05). Isovolemic hemodilution also reduced aversge infusion rates of SNP (0. 87 vs 1.22ug/kg/min., p<0.05). There were, however, no significant differences in preoperative hypertention vs normotension, mild hypothermia vs. normothermia during the operation, and male vs. female. In addition, the average infusion rates of SNP were significantly correlated with body mass index(r=0.3329, p<0.01). But those were not correlated with age, infusion time of SNP, weight, volume of transfusion, height/age, and height.

6.Preventive Effect of Lidocaine Pretreatment and Tourniquet Use on Propofol Injection Pain.
Korean Journal of Anesthesiology 2001;41(5):543-548
BACKGROUND: Pain on injection of propofol is a common problem, the cause of which remains unKnown. We evaluated the optimum time of a tourniquet with intravenous lidocaine, to decrease the intensity of pain during intravenous propofol injection. METHODS: In 72 patients undergoing general anesthesia, we subdivided all patients into 4 groups. Patients in group 1 (n = 18) received propofol only (1 mg/Kg IV) without a tourniquet, patients in group 2 (n = 18) received 1% lidocaine 20 mg IV with an upper arm tourniquet inflated to 50 mmHg applied for 1 minute followed by propofol (1 mg/Kg IV). We applied a tourniquet to patients in group 3 (n = 18) and 4 (n = 18) for 3 minutes and 5 minutes respectively. The intensity of pain along the forearm was classified in 4 degrees (none, mild, moderate, severe) by the patients and the observer simultaneously. The mean arterial pressure and heart rate were recorded before injection and at the time when the patient complained of pain. RESULTS: All groups were similar in age, sex, weight and height. The group with the tourniquet applied for 5 minutes followed by a lidocaine injection showed the lowest intensity of pain. However, between the group with 3 minutes and 5 minutes, the difference of the pain score was not statistically significant. CONCLUSIONS: We conclude that intravenous lidocaine administered after a tourniquet has been inflated to 50 mmHg for 3 minutes before propofol injection attenuates profoundly the pain associated with intravenous propofol injection.

7.The Combined Spinal Epidural Anesthesia in Total Knee Arthroplasty.
Korean Journal of Anesthesiology 1995;29(1):140-144
Spinal anesthesia has a rapid onset and requires small doses of local anesthenc to provide reliable surgical anesthesia and good muscular reiaxation but the disadvantages are the unpredictability of upper level of block, precipitous hypotension, inability to extend the block, and the risk of postdural puncture headache. A combined spinalepidural (CSE) technique can be used to reduce or eliminate some of the disadvantages of spinal and epidural anesthesia while preserving their activity. A combined spinalepidural block may combine the reliability of spinal block and the flexibility of epidural block while minimizing their drawbacks. CSE anesthesia was performed in the 19 patients scheduled for elective total knee arthroplasty. At first 17 G Tuohy needle was inserted L2-3 interspace, the epidual space would be identified, and then a long 22 G spinal needle was introduced through the Tuohy needle until the tip of the spinal needle would penetrate the dura. The correct placement of the spinal needle was confirmed by the appearence of cerebrospinal fluid at the head of needle, then 0.5% hyperbaric tetracaine 1.6-2 ml was injected into subarachnoid space. The spinal needle was withdrawn and a 18 G epidural catheter was introduced into the epidural space. If the patients complained pain during operation, 5 ml of 2% lidocaine was injected through epidural catheter, 2.5 mg Morphine was injected into epidural space for postoperative pain control after operation. Operations were well performed under CSE anesthesia and postoperative pain controls were well managed, too. The responses of the patients who has experienced CSE anesthesia were mostly good.

8.The Effect of Intrathecal NMDA and non-NMDA Receptor Antagonist on the Hyperalgesia Observed after Thermal Injury in the Rat.
Korean Journal of Anesthesiology 1998;34(4):708-715
BACKGROUND: Previous reports have described NMDA antagonist reduced the nerve injury induced or inflammatory thermal hyperalgesia. This study evaluated the effects of spinally administered excitatory amino acid antagonists on the thermal hyperalgesia state induced by mild burn. METHODS: The measured response was the latency to paw withdrawal of each hindpaw after application of a focused heat lamp on the plantar surface of the paw through a glass plate upon which the animal stood. In this work, MK801, non-competitive NMDA receptor antagonist, AP5, competitive NMDA receptor antagonist, CNQX, non-NMDA receptor antagonist were injected through chronically implanted lumbar intrathecal catheters in rats with mild burn injury on the right hindpaw. RESULTS: In the normal left hindpaw, MK801, AP5 and CNQX had little effect upon paw withdrawal latency (PWL) at intrathecal doses which do not produce readily detectable motor weakness. In the right hyperalgesic hindpaw, AP5 significantly reduced PWL at a dose-dependent fashion, MK801 reduced PWL to some extent, and CNQX did not reduced PWL. CONCLUSIONS: These results suggested that spinal NMDA receptors play an important role in the hyperalgesia induced by mild burn injury.

BACKGROUND: Pruritus, which is a frequent accompanying symptom of dermatological diseases, is also common during pregnancy, either localized or generalized. It may be related to specific dermatoses of pregnancy. OBJECTIVE: A clinical study was performed to know the exact nature of pruritus in pregnancy. METHODS: Subjects with systemic diseases, or laboratory abnormalities were excluded. People who have had pruritic dermatologic diseases before pregnancy were also excluded. One hundred and fifty five pregnant women were interviewed with physical examinations and followed up to the date of delivery. Pruritus was graded. RESULTS: Pruritus was present in 31.6%. Most affected subjects had mild or moderate severity. The abdomen was the most common site. There was a tendency for the duration of itching to increase with the duration of pregnancy. CONCLUSION: Conclusion: These findings may provide basic and useful data on pruritus during pregnancy.
