Hepatocellular carcinoma (HCC) patients with portal vein tumor thrombosis (PVTT) have a extremely poor prognosis. According to the Barcelona Clinic Liver Cancer guideline, sorafenib is a standard therapy in this situation, but many clinicians still select locoregional therapy (LRT) such as transarterial therapy, external beam radiation therapy (EBRT), even surgical resection (SR) or combination of LRTs because the survival improvement by sorafenib is unsatisfactory. Based on recent meta-analysis and prospective study, transarterial chemoembolization (TACE) and transarterial radioembolization seem to be effective and safe therapeutic option that have comparable outcome to sorafenib. Recently large nationwide studies demonstrated that SR can be a potentially curative treatment in selected patients. Hepatic arterial infusion chemotherapy (HAIC) can be also good option, especially in Child class B patients based on small volume prospective studies. Moreover, multidisciplinary strategies based on the combination of LRTs (SR plus TACE, TACE + EBRT, TACE + Sorafenib, HAIC + EBRT etc.) may improve survival of HCC patients with PVTT. Finally we discuss individualized and tailored treatment strategies for different clinical situations.

BACKGROUND: Hemichorea-Hemiballism (HCHB) can be caused by various diseases such as cerebrovascular disease, hyperglycemia, tumor, and inflammatory diseases. However, there are a few case studies using functional imaging such as single photon emission computed tomography (SPECT). METHODS: In this study, we included patients with HCHB. The patients with hyperglycemia over 250 mg/dl or high signal intensity on T1 weighted imaging were excluded. Clinical and neuroimaging characteristics of the patients were obtained and analyzed. RESULTS: We included 20 patients (M:F=12:8, mean age=67.1+/-15.3). Sixteen patients were presented with hemiballism and four with hemichorea. Six patients had no structural lesions causing HCHB. Subthalamic nucleus was the causative lesion in 6 patients. Other lesions associated with HCHB were basal ganglia, thalamus, and cortices. In a patient without structural lesion, anti-double stranded DNA antibody was detected. Brain SPECT showed not only perfusion abnormalities in the cases without structural lesions but also additional abnormalities in those with definite lesions. CONCLUSIONS: Various mechanisms were related to the development of HCHB. Functional imaging such as SPECT and immunological work-up is needed to investigate the underlying pathomechanism of HCHB.

PURPOSE: To evaluate the clinical results of operative treatment of the intra-articular calcaneal fracture with injectable calcium sulfate (MIIG(TM)). MATERIALS AND METHODS: Between March 2004 and October 2006, a total 19 intra-articular calcaneal fracture (16 patients) with a large bony defect that underwent operative treatment with plate fixation and injectable calcium sulfate (MIIG(TM)) with minimum follow-up of one year following. The mean age at time of surgery was 44.7 years (23 to 54). All of the cases were type 2 and 3 on the basis of Sanders classification. The lateral L shaped approach was used in all cases. Full weight bearing on the affected extremity was regained at an average 10 weeks postoperatively. RESULTS: The mean B?hler angle was improved from 2 degrees (-18.5~12.5 degrees) preoperatively to 23.8 degrees (12~37.5 degrees) and the angle at last follow-up was 22.5 degrees (11.5~37.5 degrees), showing about 0.3 degree decline compared to postoperative B?hler angle. Only two case of whitish leakage of graft material but other complication were none. CONCLUSION: MIIG(TM) augumentation of displaced intra-articular calcaneal fracture with large bone defect seems to bo useful method for initial stabilized and plate fixation.

PURPOSE: The distal chevron osteotomy has gained popularity for the mild to moderate hallux valgus, but necessity of fixation is controversy. No fixation of distal chevron osteotomy cause instability, but fixation has problem which has pin site infection and irritability, extension of operation time, discomfort of rehabilitation. So, the author was going to analyse and compare with and without in the fixation of distal chevron osteotomy. MATERIALS AND METHODS: Between 2004 and 2005, a total 18 patients (20 feet) following with and without in fixation of distal chevron osteotomies. The fixation group (A) was performed for the treatment of 10 patients (10 feet) and no fixation group (B) was done to 8 patients (10 feet). RESULTS: On group A, the mean first MTP (metatarsophalangeal) angle corrected 17 degrees pre-operatively to average 29 degrees (range; 20-37 degrees) and the mean first IM (intermetatarsal) angle corrected 10 degrees pre-operatively to average 15 degrees (range; 9-18 degrees). On Group B, the mean first MTP angle corrected 16 degrees pre-operatively to average 29 degrees (range; 18-33 degrees) and the mean first IM angle corrected 7 degrees pre-operatively to average 13 degrees (range; 9-16 degrees) (P>0.05). Clinical results, based on AOFAS score showed an improvement in the overall results. CONCLUSIONS: Comparing the clinical and radiographic results of the distal chevron osteotomies no difference in with and without fixation of distal chevron osteotomies.

The plica is a remnant of the synovial folds during the coalescence of three compartments of the knee at 8 weeks of fetal development. The plica are classified according to their corresponding anatomic sites of the knee, such as suprapatellar, medial patellar, infrapatellar and lateral patellar plica. The medial patellar plica is considered to be the one most likely to cause problems and has been well documented in the literature. However, there are very few reports of problems being caused by lateral plica. We encountered one case of pathologic lateral plica that was excised by arthroscopy. We report this case with a review of the relevant literature.

BACKGROUND: Patent foramen ovale (PFO) is increasingly being recognized in stroke patients. The capability of transcranial Doppler (TCD) to detect a PFO has been established. We studied the frequency of PFO in patients with ischemic stroke. METHODS: Eighty-nine patients with ischemic stroke (62 men, mean age: 56.5) consecutively underwent a contrast-enhanced TCD with monitoring of the bilateral middle cerebral arteries (MCA). The contrast solution, which consisted of 8 ml of normal saline, 1 ml of air, and 0.2 ml of patient's blood, was injected twice during normal breathing and the Valsalva maneuver. High intensity transient signals (HITS) were counted for 30 seconds after the injection. RESULTS: Patent foramen ovale was detected in 19 patients (21%). The mean age was similar in those with (55 years) and those without (57 years) PFO. Patent foramen ovale was more frequent among men (26%) than women (11%). There were no differences in the frequency of PFO among stroke subtypes (large artery atherosclerosis, 18%; small artery occlusion, 27%; cardioembolic, 27%; undetermined cause, 11%). CONCLUSIONS: Patent foramen ovale is common in patients with ischemic stroke of all subtypes.

Transarterial chemoembolization (TACE) is the worldwide procedure performed for patients with various stage hepatoceullar carcinoma (HCC), but is not yet considered as curative treatment because of relatively high local recurrence rate. Moreover, many clinicians frequently experience treatment failure (incomplete necrosis or stage progression etc.) after repeated TACE, but no clear guidelines have been recommended about salvage treatment modalities for this situation. Recently, studies for combination of radiation therapy and TACE for HCC with TACE refractoriness have been tried and reported better therapeutic efficacy. Based on above suggestions, we herein offer our experience of a patient with macrovascular invasion developed after repeated TACE that achieve complete remission by stereotactic body radiation therapy. Further study, maybe regarding a combination of locoregional and systemic therapy, is necessary on how to manage HCC patients with TACE refractoriness.

Sorafenib is the only approved targeted agent as the first line systemic therapy for treatment of advanced hepatocellular carcinoma (HCC). However, the improvement of survival duration under 3 months is far from clinical satisfactory and most patients experience disease progression within 6 months after sorafenib therapy. Unfortunately, second line systemic therapy after treatment failure of sorafenib was not established and there were no clear guidelines for salvage treatment modalities. Recently, studies suggests that combination of sorafenib and single cytotoxic agent can be relatively effective and safe strategy that achieves promising rates of local and systemic control in advanced HCC patients. Based on above suggestions, we herein offer our experience of a case achieved complete remission by combination therapy of sorafenib and tegafur in the patient with progressed disease after sorafenib therapy.

The number of older adults with hepatocelluar carcinoma (HCC) has been increasing with longer life expectancy and earlier diagnosis and treatment. However, older patients have lesser function reserve of multiple organ systems, more disability rate. Therefore, the treatment of elderly HCC patients remains a challenge worldwide. Recently, studies suggests that the survival outcome of older patients may be comparable to that of younger patients and active treatment may achieve promising rates of local and systemic control in selected patients. Based on above suggestions, we herein offer our experience of a case achieved partial remission by sequential therapy of transarterial chemoembolization after transarterial radioemoblization in elderly HCC patient with multiple metastasis. Further study, maybe regarding a combination of locoregional and systemic treatment, is necessary on how to manage HCC in elderly patients.

BACKGROUND: The National Institutes of Health Stroke Scale (NIHSS) is regarded as a valid and reliable tool to measure the severity of neurological deficits in acute stroke, but has been criticized for its complexity and variability. Therefore, the modified NIHSS (mNIHSS) was developed, eliminating redundant and less reliable items from the full version of the NIHSS. The aim of the present study was to evaluate the validity of the mNIHSS according to the subtypes of stroke and the location of affected arterial territories. METHODS: The severity of stroke in 155 patients with acute cerebral infarction was measured. Each patient was evaluated by two neurologists using both the NIHSS and mNIHSS, and the stroke subtype was determined according to the TOAST classification. The vascular territory of lesion was classified into an anterior and posterior circulation. The criterion-related validity was evaluated by the Pearson Correlation Coefficient between the NIHSS and mNIHSS scores. RESULTS: When considering the NIHSS scores as the gold criteria, the Pearson correlation coefficients of the mNIHSS were 0.96 in the subtype of large artery atherosclerosis, 0.91 in small vessel occlusion, 0.98 in cardioembolism, and 0.99 in undetermined etiology. On the other hand, the correlation coefficient was 0.98 in patients with an anterior circulation infarction, and was 0.94 in patients with a posterior circulation infarction. CONCLUSIONS: The criterion-related validity of the mNIHSS scoring system was very high in general. However, the correlations were relatively low in patients with the TOAST subtype of small vessel occlusion and also a posterior circulation infarction.
