The authors performed prospectively the transcranial Doppler monitoring of middle cerebral arteries in 37 patients with ruptured cerebral aneurysm. The entry criteria for the study were confined to the patients who had clinical Grades of 1, 2, or 3, and were operated within 4 days after bleeding. There were several sonographic risk factors of developing delayed ischemic deficits; 1) An early steep increase of flow velocity exceeding 120 cm/sec. 2) An increase of maximum flow velocity more than 140 cm/sec. 3) The flow velocity increasing simultaneously with the onset of delayed ischemic deficit in which case preventive treatment was impossible. 4) Prolonged elevation of flow velocity for more than 7 days despite of aggressive treatment. It seemed to be mandatory to start preventive and aggressive treatment for the asymptomatic patients who showed higher flow velocity than 140 cm/sec. Transcranial Doppler sonography has another potential on deciding the timing of surgery.

Valproate is one of the most popular conventional anti-epileptic drugs. It has many side effects and in rare cases, it may result in the development of parkinsonian syndromes. The parkinsonism with valproate shows insidious onset and reversible symptoms after drug withdrawal. We observed a 69-year-old woman with resting tremor, bradykinesia, cog-wheel rigidity after 2 months of valproate use. She had been suffering from epilepsy for 30 years. Her seizures were well controlled with valproate, but parkinsonian symptoms slowly progressed with doses of 1200 mg/day of valproate. After 4 months, we discontinued the doses of valproate which led to subjective and objective improvement of the parkinsonian features. The mechanism of this side effect is not well established, but GABAergic neurotransmission or mitochondrial respiratory chain may possibly be related.

To eliminate the inconvenient shortcomings of our formerly designed system for the biofeedback treatment, the development of second stage software was indispensable. PURPOSE: The aims of current study were to supplement the prototype software, and to improve the application software for the database management system. Moreover, we assessed the practical value and outcome of biofeedback therapy for the patients with functional evacuation disorders by using the upgraded system. METHODS: A new system was worked out a design to be composed of Windows based GUI (graphical user interface), DB (database) management software, and networking system. Main software performs a signal processing and a protocol making mode to train pelvic sphincter. DB program administers patient profiles and the recorded signal data. Networking system was designed to execute RS-232C serial communication of signal data with use of fast ethernet LAN networking. To affirm the reproducibility of signal display for the clinical practice, system was applied to 5 healthy volunteers. To evaluate the practical appraisal, system was applied to 27 patients with functional evacuation disorders who were undertaken anorectal physiologic tests. Patient groups were categorized as nonrelaxing puborectalis group (group I, n=17), incontinencegroup (group II, n=10). Overall patients were underwent a mean 3.7 (range, 2~10) sessions of biofeedback treatment, and the outcome was analysed in the period of 5.8 (range, 3~12) months follow-up. RESULTS: Signal data not having drift or noise were adequately processed and displayed in a real time. Specifically, data upload with use of multi-processing overay display function was appropriately embodied. Overall data and profiles of patients groups were safely saved, sorted, and reproduced by using the upgrading database management software. Regarding to the therapeutic outcomes, 63 percent of 27 overall patients (12 of 17 patients in group I, 5 of 10 patients in group II) were improved. The subjective symptoms of 2 patients in group I were recurred in a period of 3 months follow-up. CONCLUSIONS: Hardware and software functions of upgraded system were applicable to the Windows environment of personal computer. A developed system with second stage software made it possible to perform biofeedback treatment. Specifically, current results could be useful for the improvement of the motivation and patient's willingness in the self-learning process of biofeedback treatment.

The hereditary sensory neuropathy is a very rare disease characterized by prominent sensory loss without corresponding motor involvement, but may be associated with autonomic features. Currently, the disease is divided into five main types and most frequent are Type I and Type II. The type II hereditary sensory neuropathy is characterized by autosomal recessive inheritance, onset in utero or in infancy, loss of touch-pressure sense more than paintemperature sense, and almost total absence of myelinated nerve fibers. In this case, we describe a 23 years old female patient with acroosteolysis and heel ulcer who was diagnosed as hereditary sensory neuropathy type II.

OBJECTIVE: Traumatic pseudoaneurysms are rare but life-threatening lesions. We investigated the patients with these lesions to clarify their clinical characteristics and therapeutic strategies and we also reviewed the literatures on the treatment principles, possible options, and outcomes. METHODS: There were a total of 8 patients who were treated with traumatic intracranial pseudoaneurysms between April 1980 and January 2009. Medical charts and the imaging studies were reviewed for analysis. The outcome was measured with modified Rankin Scale (mRS) score at 6 months after treatment. RESULTS: All 8 patients were male and the mean age was 25 years old. Six of those were located at the cavernous segment of the internal carotid artery (ICA) and the other 2 was located at the M2 segment of middle cerebral artery. The causes of trauma were car accidents in 6, penetrating injury through the orbit in 1, and slip down injury in 1 patient. Massive epistaxis or hematemesis occurred in all patients with a pseudoaneurysm at the cavernous and ophthalmic segment of the ICA. All 6 patients of the cavernous and ophthalmic ICA group showed favorable outcome of mRS 0 to 1. The outcome of patients with middle cerebral artery pseudoaneurysm was mRS 2 to 3. CONCLUSION: Upon prompt diagnosis and proper treatment planning, it is possible to achieve favorable outcome in these patients. Lesions located at the cavernous segment of the ICA favored endovascular treatment while those at the middle cerebral artery favored surgical treatment.

Coronary artery and valvular injuries after blunt chest trauma are an unusual condition. This diagnosis is very difficult to estabilish, but prompt diagnosis and proper management are important in life saving. We report one patient who develop left main coronary artery dissection, tricuspid insufficiency, mitral insufficiency and pericardial rupture following blunt chest trauma. One year ago, he had suffered a frontal impact in a traffic accident and recieved anti-tuberculosis medication for 10 months for chest discomfort. The correct diagnosis was confirmed noninvasively by transesophageal echocardiography and the patient was treated left main coronary artery dissection flap removal, mitral valve replacement, tricuspid valvuloplasty and repair of ruptured pericardium. The postoperative course was uneventful and the patient was fully recovered.

Sinus of Valsalva aneurysms are rare cardiac anomalies and are usually caused by the separation of the aortic wall media from the valve ring tissue. These aneurysms frequently rupture into the low-pressure areas like the right ventricle and right atrium, rarely do they rupture into the left atrium, left ventricle, pericardial sac, or pulmonary artery. Cerebral infarction has been reported as a rare complication of unruptured sinus of Valsalva aneurysm. We experienced very rare two cases of Valsalva aneurysms of right coronary sinus dissecting into the interventricular septum in patients with cerebral infarction. In two cases these aneurysms ruptured into the left ventricle. These aneurysms were excised and the defect was closed with autopericardium. At the end of the surgical repair, coaptation was found to be insufficient and aortic valve replacement was undertaken.

PURPOSE: To compare the efficacy of contrast-enhanced and T2-weighted magnetic resonance urography (MRU) for the depiction of obstruction and evaluation of the causes of obstructive uropathy with that of antegrade pyelography. MATERIALS AND METHODS: Twenty-five patients with obstructive uropathy who underwent percutaneous nephrostomy (PCN) and antegrade pyelography (AGP) were included in the study. We performed MR urography, comprising half-Fourier acquisition single-shot turbo spin-echo (HASTE) T2-weighted imaging and 3-D fast imaging with steady state precession (3-D FISP) T1-weighted imaging after gadolinium enhancement and compared the quality of the images of both the HASTE and 3-D FISP MRU techniques in terms of their depiction of the dilated pelvocalyceal system, and the level, type, and causes of obstruction. RESULTS: In terms of anatomical depiction of the pelvocalyceal system (p=0.002) and the causes of obstruction (p=0.003), T1-weighted MRU using 3D-FISP was significantly better than T2-weighted MRU using the HASTE sequence. Regarding level of obstruction, T2-weighted MRU using the HASTE sequence and contrastenhanced T1-weighted MRU using 3D-FISP showed an accuracy of 76% (19/25) and 84% (21/25), respectively. In terms of type of obstruction, the accuracy of T2-weighted MRU and T1-weighted CEMRU was 72%(18/25) and 88% (22/25), respectively. CONCLUSION: T2-weighted MRU and T1-weighted CEMRU provided both anatomical information and that relating to impaired renal function. The two modelities played a complementary role and their use could decrease the unnecessary use of invasive diagnostic examination for the evaluation of obstructive uropathy.
