Objective: The patient with electrically injured myelopathy showed mild motor weakness without somatosensory pathway abnormalities. Few reports have been reported on the pathophysiological mechanisms of electrically injured myelopathy, and there is controversy about the exact pathological causes. This study aimed to investigate the ultrastructural changes in the electron microscopic findings of electrical spinal cord injury. Methods: Nine rats were used in this study. We performed 7 electrical shocks (frequency, 120 Hz; pulse width, 0.9 ms; duration, 3 seconds; current, 99 mA) using an electroconvulsive therapy (ECT) apparatus (57800 ECT unit; UGO BASILE). We used one ear and one contralateral hind limb as entry and exit sites, respectively. We only enrolled rats with hind limb weakness and performed electron microscopy evaluations of the spinal cord on the first day and 4 weeks after injury. Results: On the first day after injury, an electron microscopic examination showed a directly damaged area that appeared to be torn as physical damage, damaged myelin sheath, vacuolated axons in the myelin sheath, swollen Golgi apparatus, and injured mitochondria.Looking at changes in motor and sensory nerves, the sensory neurons showed recovered mitochondria and Golgi apparatus 4 weeks after injury; however, motor neurons still showed injured mitochondria, swollen Golgi apparatus, and endoplasmic reticulum. Conclusion This study showed that recovery from ultrastructural injury was more rapid in sensory neurons than in motor neurons.

BACKGROUND: This study was performed to evaluate the effects of a ProSeal laryngeal mask airway (PLMA) on intraoperative ventilation and blood pressure, and postoperative sore throat in laparoscopic cholecystectomy (LC). METHODS: Sixty, ASA 1 or 2 adults scheduled for elective LC were randomly allocated into two groups; i.e., endotracheal tube (ETT) or PLMA groups. General anesthesia was administered in the usual fashion. Blood pressure and heart rate were measured before and after the induction of anesthesia. Blood pressure, heart rate, peak inspiratory pressure (PIP) and end-tidal CO2 (ETCO2) also were measured before and after intraabdominal CO2 insufflation (pneumoperitoneum) at 5 minutes intervals over 30 minutes. Sore throat, nausea and vomiting were evaluated at 6 and 24 hours postoperatively. RESULTS: Blood pressure and heart rate were higher in the ETT group than in the PLMA group after induction (P < 0.05), however, no differences were observed during pneumoperitoneum. Following the induction of pneumoperitoneum, ETCO2 increased significantly, but without the group differences. PIP was less increased in the PLMA group. No significant differences were observed in incidences of postoperative sore throat, nausea or vomiting in the two groups. CONCLUSIONS: We conclude that PLMA is a useful alternative to ETT in LC. Furthermore, PLMA seems to be more useful for hypertensive patients.

BACGROUND: The purpose of this study was to evaluate the efficacy of caudal epidural steroid injection with local anesthetic for chronic lower back pain patients. METHODS: The 152 patients with lower back pain were selected for the study. The patients were treated with the caudal injections of steroid (triamcinolone acetate 40 mg) and local anesthetics (1% lidocaine 17 ml). The efficacy of caudal injections was assessed with the visual analogue scale (VAS) before procedure and at 8 weeks following procedure. RESULTS: The VAS scores of 'Before procedure' group and '8 weeks after procedure' group were 62 23 and 31 15, respectively. The caudal steroid injections provided effectiveness in treating various lower back pain diseases except postlaminectomy syndrome. CONCLUSION: We consider that caudal epidural injections of steroid and local anesthetics are effective for patients with chronic lower back pain in the short term.

INTRODUCTION: There was increase in a fall injury at the field of construction work, nowadays. There was also increase in penetrating injury by an iron reinforcing bar associated with a fall or slip injury. But this is not widely discussed in the surgical literature. The purpose of this study was to define the characteristics of injury, diagnosis, treatment and prognosis of the penetrating injury by an iron reinforcing bar associated with a fall or slip injury. METHODS AND MATERIALS: We reviewed retrospectively medical records of 17 patients who admitted and managed at Yongdong Severance hospital, Yonsei university college of medicine due to penetrating injury by an iron reinforcing bar associated with a fall or slip injury from Nov. 1987 to Dec. 1996. RESULTS: The penetrating injuries by an iron reinforcing bar associated with a fall or slip injury were 5 cases of a slip injury and 12 cases of a fall injury. The insertion site of an iron reinforcing bar was perineum in all of a slip injury. In a fall injury, insertion site was flank and back in 5 cases, perineum 4 cases, chest 2 cases and abdomen 1 case. In a fall injury, 9 patients had two or more organ injuries. CT scan was taken in 3 cases, sigmoidoscopy 3 cases and fistulogram 1 case in a slip injury. CT scan was done in 5 cases, sigmoidoscopy 1 case, cystogram 2 cases and intravenous pyelogram 1 case in a fall injury. 2 cases was cured conservatively, and operation was done in 3 cases in a slip injury in contrast to 2 cases of conservative management and operation 10 cases in a fall injury. There was no negative celiotomy. Complication was only one wound infection in a slip injury. There were wound infection 6 cases, pulmonary complication 4 cases, sepsis 1 case, necrotizing fascitis 1 case, anal sphincter injury 1 case, intraabdominal abscess 1 case and neurogenic bladder 1 case in a fall injury. There was no mortality. CONCLUSION: The penetrating injuries by an iron reinforcing bar associated with a fall or slip injury had characteristics of both penetrating and blunt injury. The chest and abdominal penetrating injuries lead to multiple organ injury. In perineal penetrating injury, we should evaluate the injury of urinary bladder, rectum and genital organ.

OBJECTIVE: This study aimed to test the possible association between Cholecystokinin B receptor (CCKBR) promoter gene and panic disorder. METHODS: 262 patients with panic disorder and 76 healthy controls participated in this study. Genotyping was performed by polymerase chain reaction-based method. RESULTS: Allele distribution of CT repeat polymorphism in patients with panic disorder was not different from those of the controls. However, after excluding the patients with panic disorder comorbid with major depressive disorder and other anxiety disorder, we found out the significant association of CCKBR (CT)n repeat with the panic disorder without comorbidities. And we analysed the data as a di-allelic polymorphism with a short (140-162 bp) and a long (164-180 bp) allele. In the di-allelic analysis, there was an excess of the shorter allele in patients with panic disorder. CONCLUSION: The present study suggested that the CCKBR promoter dinucleotide polymorphism may have a potential role for susceptibility to panic disorder in the Korean population and thus calls for consecutive studies in order to pile up the data with larger different ethnic background.
