We reviewed four patients who underwent posterior C-D occipitocervical loop and autogenous bone graft. The mean postoperative follow-up period was 16 months. The indications for surgery were progressive neurological deficit, atlantoaxial instability and intractable pain. Of the four patients, one had os odontoideum, two rheumatoid arthritis and suboccipital dislocation combined fractures of C1 and C2. Bong union was confirmed in all cases at approximately 4 months postoperatively. Final outcome result was satisfactory in three patients and unsatisfactory in one patient. The cause of unsatisfactory result was recurrent neck pain secondary to swan neck deformity. The neurologic deficit were improved or remained same as preoperative status. Three patient were out of bed on average of the 14th day postoperatively. One patient could not ambulate due to tetraplegia who needed an artificial ventilator. There was no complication related to instrumentation.

After discovery of Penicillin by Fleming in 1939, a great improvement in the treatment of osteomyelitis has been made and the mortality rate in acute stage was markedly decreased. But due to misplacement of antibiotics, and the improper treatment of the osteomyelitis, the tendency to chronicity and various sequellae of the osteomyelitis are still persist. So, it will be of importance to reconsider the management of various sequellae of pyogenic osteomyelilis. We reviewed 3 cases of sepsis, 10 cases of pathologic fracture, 6 cases of sepsis, 6 cases of malignant turnor developed in an old draining sinus, 2 cases of bone defect, 3 cases of joint contracture and 4 cases of deformity and growth disturbance 604 cases of osteomyelitis treated at National Medical Center between 1972 to 1983. The results were as follows: 1. Established sepsis was noted in 3 cases, and one of these patient dead. We treat these patients with high dose of the antibiotics accompanied by decompression of the lesion. 2. Pathologic fracture developed in 10 cases, which was treated with either conservative or operative treatment. All cases obtained good union except one. 3. Spuamous cell carcinoma developed in 6 cases around the old draining sinus. All cases were treated with amputation. Theres no recurrence except one. 4. Bone defect developed in 2 cases. A case of bone defect in humeral shaft was treated with vascularized fibular graft and obtained firm union and good function. 5. Joint contracture was treated with soft tissue release and even joint fusion in severe case. The results were not gratifying. 6. Deformity and growth disturbance of limbs were treated with soft tissue release, osteotomy and stapling. Most of the cases obtained good results, but limb length discrepancy was not recovered satisfactorily.

PURPOSE: Childbirth self-efficacy plays an important role in women's ability to cope with labor and delivery. Coaching has been gaining popularity as a way to promote cognitive, emotional and behavioral change. This study aimed to test the effects of a Coaching-based childbirth program on anxiety and childbirth self-efficacy among primigravida women. METHODS: The study design was a quasi-experimental pre-post design. A coaching-based childbirth program was developed synthesizing concepts and techniques from the literature on coaching and was verified by an expert panel. It consisted of four weekly 2-hour small group sessions. Pregnant women were recruited from H hospital in Seoul. Childbirth self-efficacy and state anxiety were measured before and after the program. RESULTS: Although there was a no significant reduction in anxiety, there were statistically significant increase for childbirth self-efficacy in the experimental group when compared to the control group. CONCLUSION: The program appears to increase childbirth self-efficacy for pregnant women. Future studies may benefit from using mixed coaching modalities and consider measuring health behaviors and obstetric outcomes to gain insights on its long-term impact.

BACKGROUND: Target point mutation of DNA topoisomerase, which is the typical mode of quinolone resistance, cannot explain high level resistance to quinolones. Therefore, many authors looked into over expression of efflux pump as the possibility. After quantificating the arcA mRNA, which controls AcrAB- TolC, the authors tried to find out the difference in the expression of arcA mRNA according to MIC of ciprofloxacin. The authors also tried to determine the usefulness of real time PCR, which is more reproducible and takes less time than preexisting immunoblot assay, through quantification of acrA. MATERIAL AND METHODS: Mutations in topoisomerase (GyrA, ParC) of 20 quinolone resistant E. coli isolates were identified by PCR and direct DNA sequencing. AcrA level was measured by real time PCR. GAPDH of E.coli was used as endogenous control. The expression of acrA was confirmed through northern hybridization method, the results obtained by real time PCR were compared. RESULTS: 1) Topoisomerase mutations were found in all quinolone resistant E. coli strains. 2) AcrA expression in fluoroquinolone-resistant E. coli was quantified by using real time PCR. There was no relationship between the ratio of acrA expression to GAPDH and MIC of ciprofloxacin. 3) With Northern hybridization, we compared the band of acrA to that of GAPDH in compactness and area. No difference in the expression according to MIC could be found. 4) The results of AcrA/GAPDH were significantly correlated between the real-time PCR and northern blot (P<0.05, correlation coefficiency 0.98). CONCLUSION: In this study, no relationship between overexpression of AcrA gene and high level fluoroquinolone resistance. Therefore, we assume that mechanism other than AcrAB efflux pump is involved in and contribute to high-level fluoroquinolone resistance. However, the degree of efflux pump expression could be confirmed with real time PCR using acrA mRNA. Therefore, real time PCR could be used in the molecular biologic study on the mechanism of resistance to antibiotics.
