Cyanide intoxication results in severe metabolic acidosis and catastrophic prognosis with conventional treatment. Indications of extracorporeal membrane oxygenation (ECMO) and continuous renal replacement therapy (CRRT) are expanding to poisoning cases. A 50-year-old male patient arrived in the emergency room due to mental change after ingestion of cyanide as a suicide attempt 30 minutes prior. He was comatose, and brain stem reflexes were absent. Initial laboratory analysis demonstrated severe metabolic acidosis with increased lactic acid of 25 mM/L. Shock and acidosis were not corrected despite a large amount of fluid resuscitation with highdose norepinephrine and continuous renal replacement therapy. We decided to apply ECMO and CRRT to allow time for stabilization of hemodynamic status. After administration of antidote infusion, although the patient had the potential to progress to brain death status, vital signs were improved with correction of acidosis. We considered the evaluation for organ donation. We report a male patient who showed typical cyanide intoxication as lethal metabolic acidosis and cardiac impairment, and the patient recovered after antidote administration during vital organ support through ECMO and CRRT.

PURPOSE: The purpose of this study was to present the results after functional reconstruction of the digits using palmaris longus tendocutaneous arterialized venous free flap in digits with compound defects. METHODS: This study is based on 29 cases of palmaris longus tendocutaneous arterialized venous free flaps harvested from the ipsilateral wrist for the reconstruction of compound defect of the digits. Over the past 10 years, we performed in 17 cases of complex defects of extensor tendon on dorsum of the digits, 7 cases of collateral ligament of the proximal or distal interphalangeal joint and 5 cases of flexor tendon defect with soft tissue defect on the palmar aspect of the digits. We assessed survival rate of the flaps and functional recovery of the digits. RESULTS: All free flaps completely survived except one with completele necrosis and another one with 50% necrosis. In cases of extensor tendon defect, the mean total active range of motion of the digits was 180degrees, in cases of flexor tendon reconstruction, it was 165degrees. In reconstruction of collateral ligament of interphalangeal joint of the thumb and digits, flexion and extension was within normal range and we got very good results without instability in all 7 cases. CONCLUSION: Palmaris longus tendocutaneous arterialized venous free flaps are very useful for reconstruction of composite defect of the digits with extensor or flexor tendons as well as collateral ligaments.

PURPOSE: Transient global amnesia (TGA) patients were retrospectively reviewed to determine the usefulness of high-field strength MRI in detecting probable ischemic lesions in TGA. MATERIALS AND METHODS: We investigated the lesion detection rate in patients with TGA using 1.5T and 3.0T MRI. Acute probable ischemic lesions were defined as regions of high-signal intensity in diffusion weighted image with corresponding low-signal intensity in apparent diffusion coefficient map. RESULTS: 3.0T MRI showed 11 out of 32 patients with probable ischemic lesions in the hippocampus with mean lesion size of 2.8 +/- 0.6 mm, whereas 1.5T MRI detected no lesion in any of 11 patients. There were no significant differences in clinical characteristics between the groups of 1.5 and 3.0T MRI. CONCLUSION: High-field strength MRI has a higher detection rate of probable ischemic lesions than low-field strength MRI in patients with TGA.

Adult polyglucosan body disease (APBD) is a rare neurological disease, characterized by adult onset (fifth to seventh decades), progressive sensorimotor or pure motor peripheral neuropathy, upper motor neuron symptoms, neurogenic bladder, and cognitive impairment. APBD is confirmed by a sural nerve biopsy that shows the widespread presence of polyglucosan bodies in the nerve. We report a 70 year old male patient who exhibited progressive weakness in all extremities and dementia. His electrodiagnostic studies showed sensorimotor polyneuropathy and muscle pathology that consisted of polyglucosan bodies located in small peripheral nerves. This is the first case of APBD reported in Korea.

PURPOSE: The arterial pulsatility index (PI) is measured by transcranial Doppler ultrasonography (TCD) and is postulated to reflect the vascular resistance distal to the artery being examined. An increased PI of the intracranial artery is often reported with diabetes mellitus (DM), old age, hypertension, intracranial hypertension, vascular dementia, and small artery disease. Microvascular complication of DM, which may contribute to cerebral infarction, involves the small perforating artery and may influence the PI of the proximal artery. MATERIALS AND METHODS: We performed a TCD examination in patients with type 2 DM with acute lacunar infarction (DML, n=35), type 2 DM without cerebral infarction (DMO, n=69), and in control cases with no DM or cerebral infarction (control group, n=41). We then compared the TCD findings among these groups. RESULTS: The PI was significantly higher in the DML and DMO groups than in the control group (1.05, 0.93, 0.73. respectively, for the right middle cerebral artery; 1.04, 0.90, 0.73, respectively, for the left middle cerebral artery; 0.97, 0.89, 0.70, respectively, for the basilar artery). The PI was also significantly higher in the DML group than in the DMO group for both middle cerebral arteries. The flow velocity was comparable among the three groups. CONCLUSION: The elevated PI of the intracranial arteries may reflect diabetic cerebral microvascular complications. The PI measurement using TCD may be a useful predictor of lacunar infarction in type 2 DM patients.

The purpose of this study is to compensate for susceptibility and a ferromagnetic body artifact using CFA and TGV on MR Imaging. A total of 30 patients (15 men and 15 women, mean age: 45 years) were performed on head and neck diseases. MR Unit used a 1.5T superconducting magnet (GE medical system, High Density). This study have investigated by changing with CFA and TGV (70, 90, 110, 130, 150) searching for compensation values about susceptibility and a ferromagnetic body artifact in 60 kg standards of body weight (p<0.05). As a quality results, Image qualities were obtained at different score from CFA and TGV (70, 90, 110, 130, 150=3.23+/-0.35, 4.31+/-0.02 4.23+/-0.21, 5.12+/-0.25, 7.13+/-0.72, 8.31+/-0.01, 5.21+/-0.15, 6.14+/-0.08, 5.23+/-0.72, 5.91+/-0.06, p<0.05). Absolute CNRs (TG, CNRpre, CNRpost) were acquired with (70:-1.44+/-0.11, -2.7+/-0.04, 90:-2.18+/-0.42, -4.41+/-0.43, 110:-2.89+/-0.43, -5.23+/-0.02, 130:-2.34+/-0.05, -5.26+/-0.01, 150: -2.09+/-0.08, -3.87+/-0.12, p<0.05). In conclusions, this study could be compensated for metal and flow artifacts surrounding the tissues having artifact by changing CFA and TGV.

Although some reports have been published on the protective effect of antibodies to Toxoplasma gondii surface membrane proteins, few address the inhibitory activity of antibodies to dense granular proteins (GRA proteins). Therefore, we performed a series of experiments to evaluate the inhibitory effects of monoclonal antibodies (mAbs) to GRA proteins (GRA2, 28 kDa; GRA6, 32 kDa) and surface membrane protein (SAG1, 30 kDa) on the invasion of T. gondii tachyzoites. Passive immunization of mice with one of three mAbs following challenge with a lethal dose of tachyzoites significantly increased survival compared with results for mice treated with control ascites. The survival times of mice challenged with tachyzoites pretreated with anti-GRA6 or anti-SAG1 mAb were significantly increased. Mice that received tachyzoites pretreated with both mAb and complement had longer survival times than those that received tachyzoites pretreated with mAb alone. Invasion of tachyzoites into fibroblasts and macrophages was significantly inhibited in the anti-GRA2, anti-GRA6 or anti-SAG1 mAb pretreated group. Pretreatment with mAb and complement inhibited invasion of tachyzoites in both fibroblasts and macrophages. These results suggest that specific antibodies to dense-granule molecules may be useful for controlling infection with T. gondii.

BACKGROUND: Despite improved operator technique and advanced equipment designs, acute closure and restenosis remain as serious limitations to both the short and long-term success of balloon angioplasty. Atherectomy is a new transluminal interventional technique for the treatment of coronary artery obstructive disease. We evaluate preliminary experience of directonal coronary atherectomy (DCA) for complex coronary artery lesions. METHODS: We tried DCA in the 16 lesions of 15 nonrandomized sequential patients(mean age 66 years, M/F : 12/3) with coronary artery lesions that were ostial lesion in 4, ulcerated and/or eccentric in 13, restenosis after PTCA in 2 and after stent implantation in 2. The target vessel was right coronary artery in 7 and left anterior descending artery in 9. RESULTS: Primary success was achieved in 14 of 16 lesions (88%) by atherectomy and in 5(36%) by additional use of balloon angioplasty. Atherectomy retrieved tissue in 15 out of 15 attempts(100%). One patients suffered acute closure due to large dissection during the DCA which was solved successfully after stent implantation. CONCLUSIONS: Atherectomy can predictably treat selected patients with eccentric, ostial bulky coronary lesions with overall safety comparable to that of conventional balloon angioplasty, although the procedure as currently performed does not appear to prevent restenosis.
