BACKGROUND: Phantom limb sensation is an unusual position sense of the extremity during nerve block that the position of extremity is misinterpreted as being flexed, or elevated, when actually they are in neutral position. Whether it is from the fixation of proprioceptive input at the time of motor blockade or from unmasking of the pattern which has been already present in the CNS is still controversial. We perfomed this study under the assumption that phantom limb sensation can still be reproduced without the influence of position at the time of nerve blockade. METHODS: Thirty-six patients scheduled for elective orthopedic surgery were randomly assigned. For 26 patients, spinal anesthesia was performed with hyperbaric 0.5% tetracaine or bupivacaine at lateral decubitus position and the position was changed to supine immediately. Existence of phantom limb sensation and the level of anesthesia was recorded at 10 and 20 minutes after injection of local anesthetics. For 10 patients, same local anesthetics were injected after patient's legs were straightened in lateral decubitus position. RESULTS: Forteen out of 26 patients whose position were changed to supine immediately after the injection of local anesthetics experienced phantom limb sensations. Five out of 10 patients whose legs were kept straight before the injection of local anesthetics experienced phantom limb sensations. Previous history of trauma was positively related to the expression of phantom limb sensation. CONCLUSION: Our data showed that the expression of phantom limb sensation is reproducible. And this was not related to the position at the time of spinal anesthesia. Trauma seems to be an important factor related to the expression of phantom limb sensation.

Cryptococcus laurentii is one of several non-neoformans cryptococci that have rarely been associated with human infection. Candida zeylanoides, an unusual Candida species, is also infrequently reported as a human pathogen. We report a case of mixed fungemia with C. laurentii and C. zeylanoides in a 12-year-old girl. The patient with acute myelogenous leukemia was receiving intensive remission induction chemotherapy through a central venous catheter (CVC) and was severely neutropenic. She had been treated with oral fluconazole prophylaxis since admission. C. laurentii and C. zeylanoides were simultaneously isolated from the peripheral blood cultures collected on days 29 and 31 of her hospital stay. The culture of the removed catheter tip grew >15 CFU of both C. laurentii and C. zeylanoides. In vitro susceptibility testing of the strains showed that the MIC of fluconazole for C. laurentii and C. zeylanoides were 8 microgram/mL and 4 microgram/mL, respectively. The patient was successfully treated by CVC removal and by treatment with amphotericin B intravenously. To our knowledge, this represents the first report of C. laurentii and C. zeylanoides fungemia in Korea.

PURPOSE:The lesion of Congenital Lipoid Adrenal Hyperplasia has been suggested to be in the 1st step of steroidogenesis of conversion of cholesterol to pregnenolone by P450scc. In 1995, however, the molecular defect of this disease has been located in the transport of cholesterol into mitochondria due to defective regulatory protein called Steroidogenic Acute Regulatory Protein(StAR), while the enzyme P450scc itself is normal. This genetic study using automatic sequence analyzer aimed at elucidating the molecular defect in the StAR gene of the two patients. METHODS:This study was performed on the two patients of Congenital Lipoid Adrenal Hyperplasia. Both children were phenotypically females. However, one turned out to have a karyotype of 46, XY, the other 46, XX. Genomic DNAs were extracted from their peripheral blood. We amplified the last exon, hot spot, of the StAR gene using 1 set of primer, S4, 5'-CCT GGC AGC CTG TTT GTG ATA G-3' AS4, 5'-CCT CAT GTC ATA GCT AAT CAG TG-3'. Subsequently, one PCR product have been directly sequenced by dideoxy termination method, and also the other products(patient's and her father's) have been sequenced by automatic sequence analyzer. RESULTS:The mutation was identified in the last exon of the StAR gene, substituting T for A at codon 258, replacing glutamine by stop codon in the two unrelated Korean patients with congenital lipoid adrenal hyperplasia. One patient were found to be homozygote, but the other to be heterozygote for the mutation. CONCLUSIONS:These results indicate that Korean children with congenital lipoid adrenal hyperplasia may be genetically identical as in Japanese. But, we discovered that the hot spot, codon 258, are not always homozygote. We want to emphasize the different point, and to say that we did experiece the automatic sequence analyzer successfully.

The molecular defect of congenital lipoid adrenal hyperplasia has been discovered to be in the transport of cholesterol into mitochondria due to defective regulatory protein called "Steroidogenic Acute Regulatory Protein (StAR)", while the enzyme P450scc itself is normal. This study with EcoRII restriction enzyme aimed at elucidating more conveniently the molecular defect in the StAR gene. The genomic DNAs were extracted from their peripheral blood. We amplified the exon 7, hot spot, of the StAR gene with 1 set of primers by Polymerase Chain Reaction (PCR). Subsequently, a PCR product corresponding to target sequence (~437 bps) from the patient and her father have been sequenced by automatic sequence analyzer. The PCR-RFLP (Restriction Fragment Length Polymorphism) analysis after restriction digestion with EcoRII restriction enzyme was also performed on 12% polyacrylamide gel electrophoresis. The mutation was identified in the exon 7 of the StAR gene, substituting C for T at codon 258, consequently replacing glutamine by stop codon. This mutation alters EcoRII restriction site. In addition, we obtained the good result of PCR-RFLP (Restriction Fragment Length Polymorphism) analysis on 12% polyacrylamide gel electrophoresis. Therefore, the PCR-RFLP (Restriction Fragment Length Polymorphism) analysis with EcoRII restriction enzyme can be easily utilized to screen carrier, diagnose the patient prenatally or postnatally.

BACKGROUND: Olfactory dysfunction is common in patients with Parkinsons disease (PD) and may precede the development of parkinsonian motor symptoms. Cardiac sympathetic denervation, which can be visualized by a cardiac (123)I-metaiodobenzylguanidine (MIBG) scan, is common in patients with PD. In this study, we evaluated olfactory functions in patients with IPD and MSA, and investigated an association between olfaction and cardiac 123I-MIBG uptake in these patients. METHODS: We prospectively enrolled 26 patients with PD, 19 patients with MSA, and 18 healthy controls. Olfactory function was evaluated with a 12-Item Cross-Cultural Smell Identification Test (CC-SIT) and Butanol threshold. 123I-MIBG (111 mBq) was injected intravenously into each subject, and cardiac uptake was imaged 3 hours later. The regions of interest were the whole heart and the mediastinum of the front image, and the ratio of 123I-MIBG uptake in the heart to that in the mediastinum (H/M ratio) was calculated. The clinical stages of parkinsonism were assessed according to the classification of Hoehn and Yahr (H&Y) and the Unified PD Rating Scale (UPDRS). RESULTS: The mean CC-SIT score in patients with PD was 4.4+/-2.2, which was significantly lower than that in patients with MSA (6.7+/-2.0) or in controls (7.3+/-2.6). There was a significant positive correlation between cardiac 123I-MIBG uptake and the CC-SIT score in patients with PD (r=0.56, p=0.003). Neither the CC-SIT score nor cardiac 123I-MIBG uptake were significantly correlated with the disease duration, the H&Y stage or motor UPDRS score. In the patients with MSA, the CC-SIT and cardiac 123I-MIBG uptake did not show a significant correlation with age (r=0.01 and r=0.11, each p>0.05), and they were not significantly correlated with each other (r=0.01, p>0.05). CONCLUSIONS: Our data suggest that the functional loss of the olfactory and cardiac sympathetic systems is closely coupled in PD.

Automatic stepping is an involuntary disorder with cyclic alternating leg movements which causes patients to appear as if walking. We report automatic stepping in patients with progressive basilar artery territory infarcts. These movements consisted of spontaneous knee flexions and ankle dorsiflexions with intermittent hip flexions, and alternating leg movements without provocation. Intervals between the movements were various from 3 to 30 seconds. Serial diffusion- weighted MRI revealed that progressive lesions were mainly located in the pontine tegmental areas.
