PURPOSE: There have been some efforts to diagnose intracranial aneurysm through a non-invasive method using MRA, although the process may be difficult when the lesion is less than 3mm. The present study prospectively compare the results of high resolution, fast speed slice interpolation MRA and DSA therapy examing the potentiality of primary non-invasive screening test. MATERIALS AND METHODS: A total of 26 cerebral aneurysm lesions from 14 patients with subarachnoid hemorrhage from ruptured aneurysm (RA) and 5 patients with unruptured aneurysm(UA). In all subjects, MRA was taken to confirm the vessel of origin, definition of aneurysm neck and the relationship of the aneurysm to nearby small vessels, and the results were compared with the results of DSA. The images were obtained with 1.5T superconductive machine(Vision, Siemens, Erlangen, Germany) on 4 slabs of MRA using slice interpolation. the settings include TR/TE/FA=30/6.4/25, matrix 160x512, FOV 150x200, 7minutes 42seconds of scan time, effective thickness of 0.7mm and an entire thickness of 102.2mm. The images included structures from foramen magnum to A3 portion of anterior cerebral artery. MIP was used for the image analysis, and multiplanar reconstruction(MPR) technique was used in cases of intracranial aneurysm. RESULTS: A total of 26 intracranial aneurysm lesions from 19 patients with 2 patients having 3 lesion, 3 patients having 2 lesions and the rest of 14 patients having 1 lesion each were examined. Among those, 14 were RA and 12 were UA. Eight lesions were less than 2mm in size, 9 lesions were 3-5mm, 7 were 6-9mm and 2 were larger than 10mm. On initial exams, 25 out of 26 aneurysm lesions were detected in either MRA or DSA showing 96% sensitively. Specificity cannot be estimated since there was no true negative of false positive findings. When MRA and MPR were used concurrently for the confirmation of size and shape, the results were equivalent to those of DSA, while in the confirmation of aneurysm neck and parent vessels, the concurrent use of MRA and MPR was far superior to the sole use of either MRA or DSA. CONCLUSION: High resolution MRA using slice interpolation technique showed equal results as those of DSA for the detection of intracranial aneurysm, and may be used as a primary nin-invasive screening test in the future.

PURPOSE: Several analgesic techniques are available for pain management after a major operation. MATERIALS AND METHODS: From December 2005 to February 2006, a prospective, double-blind study was performed involving 90 patients who had undergone a total knee arthroplasty. Patients were randomly divided into three equal groups (n=30). Demographic data, including age, height, weight, knee score, visual analogue scale (VAS), and range of flexion were evaluated preoperatively. Before wound closure, patients were given intra-synovial injections of the following solutions: patients in group I received 40mL of 300mg ropivacaine with 1:200,000 epinephrine and 5mg morphine; patients in Group II received 40mL of 300mg ropivacaine with epinephrine; and patients in Group III received 50mL normal saline as a control. All patients received an epidural patient-controlled analgesia (PCA) for 24 postoperative hours. Analgesic efficacy was evaluated using the VAS at intervals of 2, 4, 6, 12, 24, 32, 40, and 48 hours postoperatively. During this period, the side effects, the dosage of rescue analgesia required, and the range of knee flexion were recorded for each group. RESULTS: There were no significant differences among the three groups with regards to the VAS and the required dose of rescue analgesia (p > 0.05). None of the groups demonstrated significant differences in the range of knee flexion and the incidence of postoperative nausea and emesis (p > 0.05). CONCLUSION: Therefore, we found that ropivacaine, alone or with morphine, injected into the synovial tissue, along with an epidural PCA has no additional benefits in pain control after a total knee arthroplasty.

OBJECTIVE: To investigate the efficacy of infrared for lengthening applying time of cold-jet stream therapy without cold pain. METHOD: Each of the two methods of cryotherapy, cold-jet stream (CS) and cold-jet stream combined with infrared therapy (CSCI), was applied to the medial aspect of 32 volunteers' knees. The first phase was the required time that skin was dropped to 10oC with CS/CSCI. The second phase was the time for rewarming to 20oC without CS/CSCI. The third phase was the required time that skin dropped to 10degrees C again with CS/CSCI. The fourth phase was the time for re-warming to 20oC again without CS/CSCI. RESULTS: The required time which cold pain appeared after CS/CSCI were 51.3 sec and 62.3 sec, respectively, with significance (p<0.01). In CS and CSCI, first phase was 71.6 sec and 90.7 sec, respectively, and third phase was 33.2 sec and 39.9 sec, respectively (p<0.01). At second and fourth phases, it took 46.9 sec and 56.6 sec in CS (p<0.01), and took 46.9 sec and 54.6 sec in CSCI (p<0.01). CONCLUSION: As compared with CS, CSCI delayed sensation time of cold pain and prolonged application time of CS at the knee.

Herpes zoster, an acute viral infection produced by the varicella zoster virus, may affect any of the trigeminal branches. This case report presents a patient with symptoms mimicking odontogenic pain. No obvious cause of the symptoms could be found based on clinical and radiographic examinations. After a dermatologist made a diagnosis of herpes zoster involving the third trigeminal branch, the patient was given antiviral therapy. Two months later, the facial lesions and pain had almost disappeared, and residual pigmented scars were present. During the diagnostic process, clinicians should keep in mind the possibility that orofacial pain might be related to herpes zoster.

PURPOSE: Although transurethral resection of the prostate (TURP) is considered the standard surgical treatment for benign prostatic hyperplasia (BPH), Holmium laser enucleation of the prostate (HoLEP) is replacing TURP. We compared TURP with HoLEP with matching for prostate size. MATERIALS AND METHODS: We retrospectively reviewed the medical charts of patients who underwent TURP and HoLEP performed by one surgeon at our institute. All patients were categorized into 3 groups on the basis of prostate size (group 1, <40 g; group 2, 40-79 g; and group 3, >80 g), and 45 patients were selected for each method. RESULTS: No major intraoperative complications were encountered. The mean resected tissue weight was 6.3, 18.3, and 28.0 g for groups 1, 2, and 3, respectively, for TURP and 8.7, 25.0, and 39.8 g, respectively, for HoLEP. The mean operation time was 51.8, 89.3, and 101.9 minutes for TURP and 83.6, 122.8, and 131.2 minutes for HoLEP in groups 1, 2, and 3, respectively. HoLEP had better resection efficacy than TURP for any size prostate, but there was no statistical difference between the methods. Both methods resulted in an immediate and significant improvement of International Prostate Symptom Score, peak urinary flow rates, and postvoid residual urine volume. CONCLUSIONS: HoLEP is effective for BPH treatment, regardless of prostate size, even in a small prostate. The perioperative morbidity of HoLEP is also comparable to that of TURP.
