Accidental high epidural block is a rare but serious complication. It can result from many factors, which include the volume and concentration of drug, posture, puncture site, age, preg- nancy or intra-abdominal mass, and patients height and weight. We had a case of accidental high epidural block recently. This is a case report which was confirmed by an epiduragram. A healthy 50-year-old woman with a huge uterine myoma was scheduled for a total abdominal hysterectomy under continous epidural analgesia. Epidural catheterization was carried out smoothly. However, an unexpected hypotension was noticed after an epidural injection of 2% lidocaine 25 ml. Thereafter, the patient was intubated and her respiration was controlled during the opera- tion. Using the 5mg of ephedrine, her blood pressure and pulse were well maintained. The scheduled operation was carried out for one hour uneventfully, but after the operation, she felt paresthesia on her hands in the recovery room. To differentiate between the high epidural and the subdural blocks, we injected 5 ml of a water soluble Niopam 300 through the catheter postoperatively. It was observed on the epiduragram that the catheter was placed in the epidural space. It was suggested that the high epidural block was induced from the widespread diffusion through the narrowed epidural space due to the engorgement of the epidural venous plexus by the patient's huge uterine myo-ma.

Total spinal anesthesia is a well documented serious life threatening complication which results from an attempted spinal or epidural analgesia. We had an accidental total spinal anes- thesia associated with a cranial nerve paralysis and an eventual unconsciousness during epidu- ral analgesia. A 45-year-old female with an uterine myoma was scheduled for a total abdominal hysterectomy under the epidural analgesia. A lumbar tapping for the epidural analgesia was performed in a sitting position at a level between L 4, using a 18 gauge Tuohy needle. Using the Loss of Resistance technique to identify the epidural space, the first attempt failed; however, the second attempt with the same level and the technique was successful. The epidural space was identified erroneously. However, fluid was dripping very slowly through the needle, which we thought was the fluid from the normal saline which was injected from the outside to identify the space. Then 20 ml of 2% lidocaine was administered into the epidural space. Shortly after the spinal injection of lidocaine, many signs of total spinal anesthesia could be clearly observed, accompanied by the following progressing signs of intracrainal nerve paraly- sis: phrenic nerve, vagus nerve, glossopharyngeal nerve and trigeminal nerve in that order. Then female was intubated and her respiration was controlled without delay. The scheduled operation was carried out uneventfully for 2 hours and 20 minutes. The patient recovered gradually in the reverse order four hours from that time.

한국에서 분리된 콕사키 바이러스 B3 cDNA의 클로닝 및 전체 염기서열 분석

We have determined and analyzed the full-length cDNA sequence of a coxsackievirus B3 (CVB3) Korean isolate (CVB3-Korea/97) which has been known as a general human pathogen. The whole genome contains 7,400 nucleotides and has a single large open reading frame with 6,555 nucleotides that encodes a potential polyprotein precursor of 2,185 amino acids. The genome also contains a 5 non-coding region (NCR) of 741 bases and a 3' NCR of 104 bases followed by poly(A) tail. Sequence homologies of nucleotides and deduced amino acids between the CVB3-Korea/97 strain and the prototype (Nancy strain) were 81.7% and 91.5%, respectively. The genes encoding the functional proteins including viral protease and RNA dependent RNA polymerase showed higher homology than those encoding the structural proteins. We have further analyzed the sequences of 5' NCR, VP1 and VP2 of CVB3-Korea/97, which are known as cardiovirulent determining factors at the nucleotide and amino acid levels. Although the CVB 3-Korea/97 strain was isolated from an aseptic meningitis patient without cardiomyopathy, its 234th nucleotide and 165th amino acid were uracil and Asn as same as those of other cardiovirulent strains one. However, the 155th amino acid of VP1, which closely associated with cardiovirulence, was replaced with Arg by single nucleotide substitution from A2916 to T2916. Moreover, additional amino acid substitutions were observed in the flanking region of Asp155. Taken together, amino acid(s) substitution in VP1 may play a critical role in determining cardiovirulence of the CVB3- Korea/97 strain rather than individual nucleotide replacements in the 5' NCR and/or an amino acid substitution in VP2.

원주지역 설사 환자에서 분리한 Small Round Structured Viruses ( SRSV ) 염기서열 분석

Small round structured viruses (SRSV) are the major ethological agents which can cause outbreaks of non-bacterial gastroenteritis or food poisoning both in children and adults. The classification of family Caliciviridae to which SRSV belong, is based on the genome encoding three open reading frames. The rotavirus is another major pathogen which causes diarrhea in young children. We examined stool specimens obtained from diarrheal patients in Wonju from which bacterial pathogens were not found. To detect causative viruses from stool specimens of patients, reverse transcription (RT)-polymerase chain reaction (PCR) or nested PCR using rotavirus or SRSV specific primers was performed. In this study, RT-nested PCR procedure which can amplify a 330 bp fragment derived from RNA dependent RNA polymerase (RDRP) region within ORF1 was applied for the detection of SRSV. For the detection of rotaviruses, a 877 bp fragment from the VP4 region of rotavirus genome was amplified. As a result, rotavirus was not detected while SRSV sequences were detected from one out of five specimens. The nucleotide and amino acid sequences of the Wonju isolate were compared with other 6 Korean isolates which have been isolated and sequenced in our laboratory. Sequence analysis revealed that the Wonju isolate was rather distinct from other Korean isolates: the Wonju isolate was closer to genogroup I of SRSV while other 6 Korean isolates belonged to genogroup II.
