The Ilizarov fixator allows significantly more axial motion at the fracture site than the conventional monofixators. But the transfixing wires have inevitable problems of soft tissue impalement. Therefore the Rancho mounting technique, replacing the transfixing wires with half pins, has become a common place. But the increment of the axial stiffness secondary to replacing transfixing wires with half pins has not been defined clearly yet. The authors measured the axial stiffness of the Ilizarov fixator and two different configurations of the Rancho frame. The group I frame was the Ilizarov fixator composed of four rings and two transfixing wires on each ring. The group II frame was the Rancho frame and it was constructed same as the Ilizarov frame but a transfixing wire was replaced with a half pin from two central rings respectively. The group III frame was another type of Rancho frame which was constructed same as the second group but the remaining transfixing wire was replaced with a half pin from the two central rings respectively. The axial stiffness of the Group I , II and Group III frames were 71.54+/-7.21N/mm, 89.65+/-6.42N/mm, 101.01+/-7.92N/mm respectively. The axial stiffness difference between the Group I frame and the Group II frame was statistically significant(p<0.01). Also the difference between the Group I frame and the Group III frame was statistically significant(p<0.01). This study shows that the replacement of two transfixing wires with two stainless half pins resulted in significant increment of the axial stiffness of the Ilizarov frame.

The thoracic and lumbar spine fractures were usually combined with neurological deficit. But the prognostic factors in degree of neurological damage and process of the recovery are controversial. The purpose of this study is to evaluate the factors affected neurological injury and the recovery. The 31 cases who had been performed surgical interventions due to traumatic thoracic or lumbar spine fractures with the neurological deficits were studied according to the radiographic findings of the spinal columns and neurological changes of the injured cord and/or the roots. The duration of mean follow-up was 32.6 months, and all cases were evaluated by motor index score and Frankel grade. Total cases were divided into complete paralytic (N=8) and partial paralytic(N=23) group. In incomplete paraplegia group, the neurological recovery rate was better than complete group(P < 0.001) and neurological recovery period was shorter than complete group (P=0.005). The neurologic deficits according to the Frankel grade were higher in Chance fracture, flexion-distraction and translation (complete paraplegia: 4/7 cases, 57.1%) than unstable bursting fracture (complete paraplegia: 4/24 cases, 16.7%)(P=0.031). The recovery rate of Chance fracture, flexion-distraction and translation were worse than unstable bursting fracture (0.001). The fracture which occurred in T5-11 showed higher incidence of complete paraplegia(75%) compared with that of the T12-L1(30.8%) & L2-4(7.1%)(p=0.021). The neurological recovery in motor index score in L2-4 was higher than T5-11 or T12-L1(P=0.0017). There was no correlation in kyphotic deformity and anterior body height loss between complete and incomplete paraplegia groups. But the A-P diameter of compromised neural canal showed significant difference between complete and incomplete paraplegia group(P=0.027)

BACKGROUND: Diagnosis of paucibacillary leprosy is difficult owing to lack of sensitive diagnostic tools. Recently, several investigators have studied the use of polymerase chain reaction(PCR) to detect Mycobacterium leprae. Using nested-PCR the sensitivity and specificity of DNA amplification is considerably improved. OBJECTIVE: The purpose of investigation is to assess the efficacy to nested-PCR which is applied to formalin-fixed, paraffin-embedded biopsies material of patients with leprosy. METHODS: Biopsy samples were taken from patients with lepromatous(11 patients) and tuberculoid (10 patients) leprosy, fixed in formalin, and embedded in paraffin. The DNA from samples was extracted and amplified through 25 cycles by using the outside pairs of primer(L1 and L2). The second amplification was allowed to proceed through 15 cycles using inside pairs of primer(L3 and L4). RESULTS: All twenty one samples showed 347-base-pair products. To confirm that the 347-bp product did correspond to the expected portion of the M. leprae groEL gene, the amplified product was digested with Pst I. Pst I digestion yielded 254-and 93-bp fragments, as predicted from the sequence of the M. leprae gene. The sensitivity was that a single organism was identified by nested-PCR. CONCLUSION: The nested-PCR is sensitive, specific, and simple diagnostic tool for leprosy.

BACKGROUND: In anesthesia for cesarean section, there is an increased incidence of maternal awareness because a light plane of general anesthesia is chosen for fetal safety and rapid recovery. Propofol may be the choice if smooth induction and rapid maternal recovery are desired. Authors tried to know that propofol has properties which suggest that it might be useful alternative to thiopental and enflurane. METHODS: Forty patients in ASA class I or II scheduled for cesarean section were allocated randomly to either propofol (n=20) (P) or thiopental-enflurane (n=20) (T-E) group. Anesthesia was induced with propofol 2 mg/kg IV and maintained by continuous infusion of propofol 8 mg/kg/hr in P group and was induced with thiopental 4 mg/kg IV and maintained by inhalation of 1 vol% enflurane in T-E group. All patients received vecuronium 0.1 mg/kg and 50% N2O-O2. Blood pressure, heart rate, Apgar score, umbilical arterial blood gas analysis and the incidence of maternal awareness using the isolated forearm technique (IFT) were evaluated. RESULTS: Diastolic pressure was decreased in P group than T-E group at 10 min after delivery. Heart rate was increased in P group than T-E group at immediate after extubation (p<0.05). For apgar score, umbilical artery gas analysis and maternal awareness there were not significant differences between two groups. CONCLUSIONS: In comparison with thiopental-enflurane, propofol infusion (8 mg/kg/hr) coupled with N2O was proved to be clinically satisfactory anesthesia for cesarean section with no adverse effects on both mother and neonate.

Congenital diverticulum of the left ventricle is a very rare disease. Ventricular diverticulum is usually associated with other anomalies including intracardiac and midline thoracoabdominal defect. We describe a case with congenital left ventricular diverticulum presenting as an isolated lesion. A 37-year-old man presented with 4-year history of chest pain. Diverticulum was diagnosed by echocardiography and left ventriculogram.

Endometriosis at the site of episiotomy scar following vaginal delivery and abdominal scar following cesarean section are rare conditions among the extrapelvic endometriosis implantation. We have experienced five cases of extrapelvic endometriosis : four cases at the site of abdominal scar following cesarean section, and one case at the site of episiotomy scar following vaginal delivery. We report the five cases with brief review of the concerned literature.
