We reported the two cases of olecranon osteomyelitis secondary to the iatrogenic chronic relapsing septic olecranon bursitis. Infection was well eradicated by excision of the infected bursa and curettage of the eroded olecranon under the coverage of antibiotic therapy.

PURPOSE: Recent developments in minimally invasive techniques have the potential to reduce surgical morbidity, promote patient recovery, accelerate surgical procedures, and thus improve cost-effectiveness in case management. In this study, we compared the treatment efficacy and results of supraorbital keyhole approach (SOKA) with those of conventional unilateral frontal craniotomy (CUFC) for traumatic intracerebral hemorrhage (TICH) in the frontal lobe. METHODS: We analyzed the data of 38 patients who underwent CUFC (n=30) and SOKA (n=8) and retrospectively reviewed their medical records and radiological findings. Furthermore, we tried to identify the best surgical method for such lesions by including patients who underwent burr hole aspiration and drainage (BHAD) (n=9) under local anesthesia due to various circumstances. RESULTS: The difference in the initial Glasgow coma scale score, operative time, and length of hospitalization between the CUFC and SOKA were statistically significant. All radiological features between the two groups including associated skull fracture, amount of pre- and postoperative hematoma, percentage of complete hematoma removal, pre- and postoperative midline shifting of the hematoma, and development of postoperative delayed hematoma were not statistically significant. Our experience of 46 patients with TICH in the frontal lobe with any of the three different surgical methods including BHAD enabled us to obtain valuable findings. CONCLUSIONS Although it is difficult to insist that one particular approach is more useful than the other, we are confident that SOKA will have more advantages over CUFC in carefully selected patients with frontal TICH depending on the surgical experience of a neurosurgeon.

BACKGROUND: Percutaneous vertebroplasty (PV) is a minimally invasive, image-guided therapy used to relieve pain from osteoporotic vertebral compression fractures. Venography before injection of bone cement has been advocated as a means of identifying sites of potential venous leakage during the procedure. However, venography has been used only in selected situations, and its need is debatable. We aimed to analyze the usefulness of venography with percutaneous vertebroplasties for osteoporotic compression fractures and to report our recent experiences in treating such patients. METHODS: One hundred PVs performed on 93 patients were evaluated. To identify the usefulness of venography, our cases were divided into 2 groups. Group A patients had venographies before the PVs, whereas Group B patients were treated without venography. We analyzed their clinical status, pain status, and complications linked to leakage of bone cement. RESULTS: There were no significant differences in any of the collected data for the two groups. CONCLUSION: Our results indicate that PVs can be performed safely without venography beforehand. However, venography may be beneficial for less experienced physicians or trainees.

OBJECT: It is reported that the effect of antipsychotics on the extracellular dopamine levels in the prefrontal cortex is related to the their effect on the negative symptoms. Therefore, we investigated the acute and chronic effects of olanzapine and risperidone on the extracellular dopamine concentrations in the prefrontal cortex of rat. Samples were obtained using in vivo brain microdialysis. METHOD: Dopamine levels in the samples were measured by high pressure liquid chromatography with electrochemical detection. RESULTS: 1) Both the acute treatment of olanzapine and risperidone increased the extracellular dopamine concentrations in the prefrontal cortex, dose-dependently. 2) There was a no significant difference in the maximal change of the extracellular dopamine concentrations in the prefrontal cortex induced by the acute treatment of olanzapine and risperidone. 3) Both the chronic treatment of olanzapine and risperidone also increased the extracellular dopamine concentrations in the prefrontal cortex, but they showed the tolerance effect that the degree of increase was smaller than that of the acute treatment. 4) As for the maximal changes of the extracellular dopamine concentrations in the prefrontal cortex induced by the chronic treatment of olanzapine and risperidone, the effect of the former was greater than that of the latter. CONCLUSION: These results suggest that the effects of olanzapine and risperidone on the negative symptoms are related to the increased extracellular dopamine concentrations in the prefrontal cortex induced by these drugs.
