OBJECTIVE: The objective of this study was to determine the relationship between the fetal doppler flow velocimetry and birth weight in low risk pregnancy population. METHODS: From December 1995 to May 1996, We prospectively performed doppler study in 254 uncomplicated, term pregnant women, who visited Pohang Hospital, Dongguk University. Using pulsed color doppler, we measured umbilical artery RI, middle cerebral artery RI and middle cerebral-umbilical artery RI ratio within one week before delivery. RESULTS: The result was that low birth weight group (below 2500gm) had very significant lationship with umbilical artery RI(P<0.01), middle cerebral artery RI(P<0.05) and middle cerebral-umbilical artery RI ratio(P<0.05), but there was no significant relationship in these blood flow indices between normal birth weight group (2501gm- 3999gm) and macrosomia group (above 4000gm). CONCLUSIONS: We concluded that application of doppler ultrasonopaphy in the assessment of fetal weight is somewhat helpful for identification of low birth weight, not for macrosomia.

BACKGROUND: It has been well known that absolute and interpeak latencies of brainstem auditory evoked potentials (BAEP) are usually prolonged in diabetics. However, Its etiology is still controversial. We tried to identify whether the cause is structural or metabolic in origin by performing BAEP and brain MRI in the diabetic patients. METHODS: BAEP were performed in both the diabetic patients (DM) group (16 males and 15 females) and the normal control group (25 males and 33 female). A brain MRI was performed in the DM group on those who showed abnormal BAEP and com-pared the results of BAEP of the DM group with those of the control group. RESULTS: 7 patients (22.6%) showed abnor-mal BAEP (male; 6, female; 1, unilateral; 4, bilateral; 3) when abnormal BAEP was defined as being larger than two and a half standard deviations of the control group BAEP results. Two males of the DM group who showed abnormal structural lesions of the pons in their brain MRI were not included in the statistical analysis. The remaining 14 diabetic male patients (mean age: 58.7 +/-9.1 years, mean disease duration: 6.1 +/-4.7 years, mean hemoglobin (Hb) A1C: 7.7 +/- 2.0%) and 15 diabetic female patients (mean age: 60.6 +/-10.8 years, mean disease duration: 5.4 +/-5.1 years, mean HgA1C: 7.8 +/-2.1%) were stastistically analyzed. Interpeak latencies of I-III, III-V, and I-V were found to be signifi-cantly prolonged in the DM group. The prolongation of interpeak latencies of I-III and I-V were found to be signifi-cantly correlated with the disease duration only in the diabetic female patients, but not with age and HbA1c. CONCLUSIONS: These findings suggest that both metabolic derangement and structural lesion contribute to prolonging the central conduction time on BAEP pathway in diabetics.

BACKGROUND: The photsensitizing effect of quinolones has been recognized since their introdulation as an antibacterial agents. Recently several new second eneration antibacterial agents of this pharmacological class have become available for therapy, and are gaining increasing impotance. OBJECTIVE: To reveal the phototoxic potentials of some new quinolones by photohemolysis test, estimation of fluorescenc spectra, and Candida albicans test. METHODS: Nalidixic acid and four second-generation quinolones(ciprofloxacin, enoxacini, norfloxacin, and ofloxacitid were examined by fluorescence spertra which measured t.he phototoxc potentials by photochemial instability, photohemolsis test for the phototoxic properties against cell membranes and Candida tlbicans test for phototoxic properties against DNA. RESULTS: All drugs showed a fluorescence spectra within 360 nm to 450 nm, and in the photohemolysis test, all studied drug except ofloxacin got above 5% hemolytic value, and all drugs showed clear zone. in Candida albicans test after 48hours. CONCLUSION: These results suggested that all tested drugs were photochemically unstable. According to the mechanisris of cellular phototoxicity, ciprofloxacin, enoxacin, and norfloxacin was phtototoxic to nucleus and cell membrane, whereas ofloxacin was phototoxic to nucleus only.

PURPOSE: To review the results and discuss the technique for an extended trochanteric osteotomy through the lateral approach in revision total hip arthroplasty. MATERIALS AND METHODS: Twenty patients were reviewed after an average follow-up of 30.4 months (range, 24-56 months) between 1999 and 2003. The indications for the extended trochanteric osteotomy included the removal of a well-fixed cemented or cementless stem in 12 hips, varus remodeling of the femur in 3 hips and trochanteric malposition in 5 hips. The length of the osteotomy, the proximal migration of the osteotomized fragment, the fixation status of the femoral stem, the union status of the osteotomy site and complications were evaluated at the last follow-up. RESULTS: The mean length of the osteotomy was 12 cm (range, 8-20 cm). Radiographic union of the osteotomy site was noted in all cases after an average of 3.8 months (range, 2.5-6.0 months). The mean migration of the osteotomized fragment was 2.4 mm (range, 0-8 mm). The complications included postoperative dislocation in 3 hips and fractures of the osteotomy fragment in 2 hips, which were treated at the last follow up. Fixation of the stem with bone ingrowth was noted in all patients. CONCLUSION: An extended trochanteric osteotomy through the lateral approach can be performed safely in complex revision total hip arthroplasty.
