BACKGROUND AND OBJECT: Cheiro-oral syndrome (COS) is characterized by a sensory disturbance in the unilateral hand and ipsilateral mouth corner. It is usually due to a lesion in the parietal cortex, thatamocortical projections, thalamus, or rarely brain stem. However, the syndrome is relatively unknown and rarely mentioned in most neurological textbooks. We presented ten cases of COS with a review of the clinical symptoms and signs and the neuroradiological methods used to demonstrate the responsible site. METHODS AND RESULTS: We studied 10 patients with stroke who showed restricted sensory disturbance on the one hand and ispilateral mouth. The study forms consisted of clinical manifestaion, neurological examination, electrophysiological, and neuroradiologic studies. Computed tomography and/or magnetic resonance imaging identified lesion in the thalamus in 5, brain stem in 3, and corona radiata in 1 patient. But, the anatomical responsible site for one case was not founded. Infarction had occurred in nine cases and hemorrhage in one. Seven of the 10 patients showed sensory disturbances restricted to the perioral area, hands, fingers when they were first examined; the remaining patients complained more diffuse sensory disturbances at first, but it had become restricted to perioral and fingers, usually within 2-3 weeks. The durations of symptom varied from 5 days to more than 15 months and these symptoms were improved within 2-3 weeks to 4 months in treated patients. CONCLUSION: When the symptoms and signs of the COS were presented, especially if a history of migraine is lacking, neuroradiological methods such as CT or MRI should be undertaken to localize and diffentiate the nature of lesion.

PURPOSE: In this study, the medication effects of Milnacipran and Pregabalin, as well known as fibromyalgia treatment medicine, in fibromyalgia syndrome patients were compared through the change of BOLD signal in pain related functional MRI. MATERIALS AND METHODS: Twenty fibromyalgia syndrome patients were enrolled in this study and they were separated into two groups according to the treatment medicine: 10 Milnacipran (MLN) treatment group and 7 Pregabalin (PGB) treatment group. For accurate diagnosis, all patients underwent several clinical tests. Pre-treated and post-treated fMRI image with block-designed pressure-pain stimulation for each group were obtained to conduct the statistical analysis of paired t-test and two sample t-test. All statistical significant level was less than 0.05. RESULTS: In clinical tests, the clinical scores of the two groups were not significantly different at pre-treatment stage. But, PGB treatment group had lower Widespread Pain Index (WPI) and Brief Fatigue Inventory (BFI) score than those of MLN treatment group at post-treatment stage. In functional image analysis, BOLD signal of PGB treatment group was higher BOLD signal at several regions including anterior cingulate and insula than MLN treatment group at post-treatment stage. Also, paired t-test values of the BOLD signal in MLN group decreased in several regions including insula and thalamus as known as 'pain network'. In contrast, size and number of regions in which the BOLD signal decreased in PGB treatment group were smaller than those of MLN treatment group. CONCLUSION: This study showed that MLN group and PGB group have different medication effects. It is not surprising that MLN and PGB have not the same therapeutic effects since these two drugs have different medicinal mechanisms such as antidepressants and anti-seizure medication, respectively, and different detailed target of fibromyalgia syndrome treatment. Therefore, it is difficult to say which medicine will work better in this study.

PURPOSE: We evaluated whether Cyberknife radiosurgery is an effective and safe method of therapy for medically intractable trigeminal neuralgia (TN). MATERIALS AND METHODS: We retrospectively analyzed the outcome of 26 patients, who failed to surgery or were not suitable candidates for invasive intervention and were treated by Cyberknife radiosurgery between March 2004 and May 2005. Radiosurgery doses of 60~64 Gy were delivered to the 80% isodose line prescribed to an 6 mm length of the nerve, sparing the most proximal 3 mm away from the trigeminal nerve root entry zone (median dose: 64 Gy). RESULTS: Follow-up period was 3~15 months (median follow-up period: 9 months) Preliminary results from a cohort of 26 patients undergoing Cyberknife radiosurgery for TN showed that pain relief was achieved in 50% (13/26) of patients within the first 24 hrs after treatment. At last follow-up, 96.2% (25/26) of patients reported early pain relief within 7 days. Treatment failure developed in 2 of 26. Poor response occurred in one patient and relapse was observed in the other patient. 3 patients had hypoesthesia (11.5%), which was the only complication observed with any of our patients. CONCLUSION: With these results, authors assumed that Cyberknife radiosurgery for TN could be one of safe and effective therapeutic methods.

There have been many reports regarding complications associated with cardiopulmonary resuscitation(CPR) and it may be true that there are many unrevealed complications. Although it is used to say that 'any CPR is better than no CPR', inadvertent or inadequate CPR may insult in serious organ injury. This report describes a 64-year-old woman who suffered Mallory-Weiss tear resulting from inadvertent cardiopulmonary resuscitation by a bystander who had never been trained. Possible mechanisms of gastric injuries caused by CPR are suggested, and importance of adequate CPR training are emphasized in this report.

PURPOSE: To compare the findings of MR cholangiography with those of ultrasound and biochemistry in patients with suspected choledocholithiasis, and to evaluate the clinical utility and role of MR cholangiography prior to laparoscopic cholecystectomy. MATERIALS AND METHODS: We retrospectively reviewed the radiologic findings and clinical records of 103 consecutive patients in whom choledocholithiasis was suspected and who underwent both ultrasound and MR cholangiography. For MR imaging, a 1.5T unit was used, and axial T1-FLASH, True FISP, and oblique coronal HASTE and RARE images were obtained. Initial biochemical values (AST, ALT, total bilirubin) were correlated with the findings of MR cholangiography. RESULTS: Choledocholithiasis was present in 36 of 103 patients: overall, there were 34 true-positive, 63 truenegative, four false-positive, and two false-negative results. In the detection of choledocholithiasis, MR cholangiography showed the following characteristics: sensitivity, 94%; specificity, 94%; positive predictive value, 89%; negative predictive value, 96%; accuracy, 95%. Calculi in the common bile duct were detected in 3 of 33 patients (9%) in whom ultrasound showed that the caliber of the common bile duct was normal and whose laboratory findings were normal, and in 12 of 43 (28%) of those whose common bile duct was dilatated or whose laboratory values were abnormal. Calculi were present in the common bile duct of 21 of 27 patients (78%) with abnormal laboratory values and abnormal ultrasound findings. CONCLUSION: Choledocholithiasis was detected in 25% of patients without clinical suspicion and was not present in 25% of patients with strong clinical suspicion. In patients with this condition, MR cholangiography is noninvasive and accurate, and we suggest that in patients with suspected choledocholithiasis, it should be a routine diagnostic procedure prior to laparoscopic cholecystectomy.

BACKGROUND/AIMS: In the bare-metal stent era, routine follow-up coronary angiography (RFU CAG) was used to ensure stent patency. With the advent of drug-eluting stents (DESs) with better safety and efficacy profiles, RFU CAG has been performed less often. There are few data on the clinical impact of RFU CAG after second- or third-generation DES implantation in clinically stable patients with coronary artery disease; the aim of this study was to examine this issue. METHODS: We analyzed clinical outcomes retrospectively of 259 patients who were event-free at 12-month after stent implantation and did not undergo RFU CAG (clinical follow-up group) and 364 patients who were event-free prior to RFU CAG (angiographic follow-up group). Baseline characteristics were compared between the groups. RESULTS: The Kaplan-Meier estimated total survival and major adverse cardiac event (MACE)-free survival did not differ between the groups (p = 0.100 and p = 0.461, respectively). The cumulative MACE rate was also not different between the groups (hazard ratio, 0.85; 95% confidence interval, 0.35 to 2.02). In the angiographic follow-up group, 8.8% revascularization was seen at RFU CAG. CONCLUSIONS: RFU CAG did not affect long-term clinical outcome after second- or third-generation DES implantation in clinically stable patients.

BACKGROUND: Laparoscopic surgery is replacing conventional surgical techniques due to its many advantages. However the possibility of respiratory complications during CO2-induced pneumoperitoneum remain. Tracheal gas insufflation (TGI) has been shown to be a useful adjunct to mechanical ventilation in hypercapneic patients. This study investigated the effectiveness of TGI in reducing the PaCO2 level in hypercapneic patients during laparoscopic surgery without increasing the peak inspiratory pressure (PIP) and usefulness of a Univent tube(R) as a device for TGI. METHODS:Twenty-four patients who were scheduled to undergo gynecological laparoscopic surgery, were enrolled in this study. Anesthesia was induced and maintained with propofol, rocuronium and N2O-O2-sevoflurane. The suction port of the endobronchial blocker of the Univent tube(R) was used for the path of TGI. Data including the ABGA and respiratory parameters were measured three times, the pre-CO2 peritoneum (pre-CO2 pneumoperitoneum point, PCP), 15 min after CO2 peritoneum (after-CO2 pneumoperitoneum point, ACP) and after 15 min TGI (TGI point, TGIP). RESULTS: At ACP, the PaCO2 and PIP had increased more significantly than PCP. After TGI, the PaCO2 was decreased more significantly than ACP, but the PIP did not increased. CONCLUSIONS: TGI is a useful adjunct to mechanical ventilation in hypercapneic patients during laparoscopic surgery, and a univent tube(R) is an economic and convenient device for TGI.

The purpose of this study was to compare the shaping ability of three Ni-Ti file systems used by dental students or the experts and consequently to aid in choosing a proper systems for educational courses of dental students and beginners. Fifty students and ten dentists who have clinical experience over two years prepared 180 simulated root canals in resin blocks with three Ni-Ti systems; ProFile(R) (PF), HeroShaper(R) (HS), K3TM (K3). After preparation, the Ni-Ti files were evaluated for distortion and canal preparation time was recorded. The images of pre- and post-instrumented canals were scanned and superimposed. Amounts of increased canal widths, deviation, and centering ratio were calculated at apical 1, 3 and 5 mm levels and statistical analysis was performed. The results were as follows: 1. HS showed the shortest preparation time and instrumented canal width in K3 was significantly larger than other groups (P < 0.05). 2. At 1 and 3 mm levels, all groups had outward deviation. In student group, at the 1 mm level, PF had the least deviation (P < 0.05). 3. In the centering ratio, the PF had the best centering ability compared to the others at 5 mm level. At 1 and 3 mm levels, HS and PF had better abilities than K3. Student group had better ratio than the expert at 3 mm level with PF (P < 0.05). Based on the results, it is surmised that the ProFile(R) is the safest and most ideal instrument for students and beginners.
