OBJECTIVETo explore an optimal anesthesia method with less impact on hemodynamics and electrocardiogram (ECG) of old patients with coronary artery disease (CHD) during abdominal operation.

METHODSThe 133 CHD patients waiting for abdominal operation were randomly divided into continuous epidural anesthesia (EA) group, general anesthesia group (GA) and combined spinal-epidural anesthesia (CSEA) group. Continuous monitoring was carried out during operation and mean arterial pressure (MAP), heart rate (HR), oxygen saturation (SaO2), abnormal ECG were measured respectively at different time for comparison and the differences of the above hemodynamic parameters and abnormal ECG features were compared among the 3 groups.

RESULTSAt the 15 min and 30 min point after anesthesia, SaO2 in GA group was significantly increased compared to that in the EA group (P < 0.05). At 15 min, 30 min and 60 min point after anesthesia, MAP in CSEA group was significantly increased compared to that in the EA group (P < 0.05). At 30 min point after anesthesia, HR in CSEA group was increased significantly compared to the EA group (P < 0.05). At 15 min and 30 min point after anesthesia, SaO2 in the CSEA group was increased significantly compare to the EA group (P < 0.05). Compared with preanesthesia (T0) in EA group, MAP, HR and SaO2 decreased significantly at 15, 30 and 60 min after anesthesia (P < 0.05). The fluctuation of the three parameters in GA and CSEA groups were relatively small (P > 0.05). As well as the comparison of abnormal ECG among the 3 groups was concerned, the incidence of ST-T changes in GA and CSEA groups were significantly lower than that in EA group at the time of 15 min, 30 min and 60 min after anesthesia and at the time of surgery termination (P < 0.05, P < 0.01). The incidence of arrhythmia in GA and CSEA groups were significantly lower than that in EA group at the time of 15 min, 30 min and 60 min after anesthesia (P < 0.05, P < 0.01). Compared with T0 in the same group, the incidences of ST-T changes and arrhythmia in GA or CSEA group at the time of 15, 30 and 60 min after anesthesia and at the time of surgery termination were significantly lower than that before anesthesia (P < 0.05, P < 0.01).

CONCLUSIONGA and CSEA have less impact on hemodynamics and have smaller incidence of abnormal ECG of old CHD patients with abdominal operation.

Objective To evaluate the clinical outcome of external bracket fixation in the treat- ment of complex tibia diaphysis fracture involving intra-articular fractures.Methods Forty-two cases of complex tibia diaphysis fracture with proximal and distal intra-articular fractures treated surgically in our hospital from January 1999 to January 2004 were analyzed.The complex tibia diaphysis fractures were categorized according to the AO classification as type C2 (multiple segments fracture) and type C3 (ir- regular fracture),proximal and distal intra-articular fractures in 23 and 19 cases,respectively.Definite operation was done within one week.Twenty-two cases were treated with simple external fixator,and 20 cases treated with screws and external fixator.Results All the 42 cases were followed-up regularly. According to AO evaluation of the knee and ankle joint movement,83% (35/42 cases) of the cases gained satisfactory functional outcome,14% (6/42 cases) had quite satisfactory results and 2% (1/42 case) had unsatisfactory functional outcome.Conclusion External bracket fixation can obtain outcome of relative length of the tibia and fibula,tube structure reconstruction,smoothness of the articular surface and the parallel and symmetric relation of knees and ankles for complex tibia diaphysis fracture with proxi- mal and distal intra-articular fracture.The arthritis resulting in pain in movement and restriction of func- tion is considered to be the most important factor affecting the joint function.Early functional exercise is important for best recovery of knee and ankle function.

Melioidosis is an infectious disease caused by a Gram-negative bacterium thought to be caused Burkholderia pseudomallei. This disease is endemic in tropical regions, but is not endemic and is rarely encountered in Korea. Nevertheless, the importance of early diagnosis of melioidosis is drawing substantial attention, due to its proliferation and the high mortality caused by the disease. Melioidosis can attack any organ, and manifests with a variety of symptoms. In particular, musculoskeletal melioidosis is rare and presents with nonspecific musculoskeletal symptoms. The imaging features of musculoskeletal melioidosis manifest a form of osteomyelitis or septic arthritis with soft tissue abscess or can mimic a bone tumor. This study describes the clinical and imaging findings of melioidosis involving the right femur and hip joint in a 64-year-old man.

BACKGROUND AND OBJECTIVES: The transradial approach has been suggested as an alternative entry site for coronary angiography. The complication and success rates of the vascular procedure have been associated with age. The aim of this study was to determine the safety, feasibility, and efficacy of transradial coronary angiography for patients greater than age 70 compared with younger patients. SUBJCETS AND METHODS: Clinical and angiographic data were reviewed retrospectively in 894 consecutive patients who underwent transradial coronary angiography from January 2001 through May 2003. Procedure-related results were used to compare 2 groups, patients aged < 70 years and those >70 years. RESULTS: In a consecutive series of 894 patients, 638 were < 70 years of age and 256 were >70 years of age. There was no significant difference in the rate of success in patients >70 years compared with patients < 70 (91.1% vs 93.6%). No severe complications, such as death, vascular dissection, rupture, and major cerebrovascular accidents were present in either group. Procedure-related variables, including procedure time, radiographic contrast use, and the number of catheters used per case, were similar between the two groups. CONCLUSION: Transradial access is a safe and feasible approach for coronary angiography in elderly patients, yielding results similar to those achieved with younger patients.

OBJECTIVETo investigate the effects of propentofylline on the expressions of glial fibrillary acidic protein (GFAP) and TNF-alpha and its action mechanism in the rat model of chronic prostatitis pain (CPP).

METHODSWe equally randomized 30 male SD rats to groups A (sham operation), B (CPP model) and C (propentofylline intervention). After modelling, the rats in group C received intraperitoneal injection of propentofylline at 2 mg/kg, while those in groups A and B were injected intrathecally with the same dose of normal saline. At 15 days after the treatment, we examined the expressions of GFAP in the spinal cord and TNF-alpha in the prostate by immunohistochemistry.

RESULTSThe levels of GFAP and TNF-alpha were obviously lower in group A (2.56 +/- 0.16 and 1.34 +/- 0.05) than in B (16.79 +/- 0.72 and 3.46 +/- 0.05) and C (8.83 +/- 0.63 and 2.25 +/- 0.05), significantly increased in B as compared with A (P < 0.05). And the increase was markedly less in group C than in B (P < 0.05).

CONCLUSIONPropentofylline inhibits chronic prostatitis pain in the rat model by suppressing the activation of astroglia and the release of inflammatory mediators.

We report our experience with unusual cases of Peyronie`s disease concurrent with venogenic impotence. Three patients have suffered from distressful sexual life including painful erection. penile curvature and poor penile tumescence. Following multidisciplinary work-ups for impotence in those patients. it proved be that they had venogenic impotence as well as Peyronie`s disease. Since intrapenile triamcinolone injection therapy did not improve their symptoms. a single-staged, surgical procedure was performed to resolve problems with Peyronie`s disease and venogenic impotence at a time in each patient It was proceeded with ligation of penile vein. excision of the fibrous plaque and replacement with dermal graft respectively. In a patient. additional Nesbit`s procedure was required to correct sustained penile curvature. Postoperative follow-up for 2 years shows that all the patients have remained Free from serious problem in their sexual life. We believe that above single-staged operation is worth application to the case of Peyronie`s disease concurrent with venogenic impotence.
