OBJECTIVE: Although ovarian cancer is the leading cause of death among all cancers of the female reproductive tract, the genetic alterations involved in ovarian cancer remains largely unknown. Recently, mutations of the p53 gene have been documented in many types of human cancer including ovarian cancer. METHODS: In tbe present study, p53 gene mutation was examined in DNA samples extracted from paraffin embedded surgical specimens of ovarian cancer. Furthermore, clinicopathological parameters were examined in relation to p53 gene mutation in order to understand the role of p53 mutation in the development of ovarian cancer. Using the polymerase chain reaction(PCR) and single strand conformational polymarphism(PCR-SSCP), p53 gene mutation was examined and the mutations were confirmed by DNA scquencing in 17 cases of ovarian cancer. RESULTS: Abnormal bands indicating mutation were detected in 2/17(11.8%). DNA sequencing confirmed in 2 mutations and revealed C to T and A to T nucleotide chmges. In clinicopathological parameters, FIGO stage, grade, and recunence were not correlated with the p53 gene mutation. However, the recurrence rate was higher in patients with mutant p53 compared with those with wild type p53(50.0% vs 13.3%), altbough this is not statisticaUy significant. CONCLUSION: In conclusion, p53 gene mutation shows no correlation with stage, grade and recurrence, and p53 gene mutation does not appear to be a marker that predicts the biological behavior or the outmme of the disease. This study suggested useful data to elucidate the mechanism of chemotherapy-resistant ovarian cancer and further p53 expression assay would be mandatory for p53 nonfunctioning ovarian cancas.

Oxybutynin chloride was administered intravesically in 7 spinal cord injury patients with persistent incontinence and frequent side effects on oral medication. Five mg tablets were dissolved in 20 ml normal saline, and the solution was instilled twice daily and retained for 30 minutes. All patients reported subjective improvement following treatment and all became totally continent. No side effects were observed. In urodynamic study mean bladder capacity increased from 250 to 400ml(P = 0.005) and mean maximum filling pressure decreased from 25 to 18cmH2O (P = 0.283). In conclusion treatment with intravesical oxybutynin chloride can be effective in spinal cord injury patients who either are unresponsive to or have intolerable side effects on oral medication.

Recent improvements in gray scale ultrasonic imaging and the development of real time ultrasound made it useful in directing the diagnostic examination and in determining which patients should undergo further, more invasive diagnostic procedures. Ultrasound scanning is cheaper and quicker than computed tomography and angiography, is not invasive and causes little discomfort to the patient. No intravenous contrast medium is used so that reactions to iodine and the difficulty in obtaining venous puncture, frequently a problem in children, are circumvented. There is no ionizing radiation or problem with breath holding. So we made a brief review of the clinical experience and value of ultrasound of renal diseases.

BACKGROUND: Epidural anesthesia is becoming an increasingly important aspect of anaesthetic practice because it has many advantages. To achieve the appropriate sedation, various methods have been described. The authors applied the ketamine for this purpose in subanesthetic dose and compared with the midazolam that has been most commonly used for intravenous sedation. METHODS: Fifty-seven adult patients undergoing lower abdominal and extremity surgery who were receiving epidural anesthesia were randomely enrolled into this clinical study. They were allocated to three groups to receive only normal saline (group C), midazolam 0.05 mg/kg (group M) and ketamine 0.5 mg/kg midazolam 0.05 mg/kg (group K) in normal saline 10ml, respectively. Hemodynamic and respiratory measurements were recorded at baseline, 1 minute, 3 minute, 5 minute, 10 minute, 20 minute and 30 minute after sedation. The degree of sedation was assessed by a blinded observer using sedation score. RESULTS: There were no significant differences for hemodynamic and respiratory parameters, but decrements of arterial pressure at 1 minute after sedation were most remarkable in the group M. Sedation was satisfactorily achieved by combination of ketamine and midazolam without significant emergence reaction. CONCLUSIONS: The combination of ketamine and midazolam was judged to be suitable alternative for sedation during epidural anesthesia.
