BACKGROUND: Drug-induced Parkinsonism(DIP) is the second commonest cause of Parkinsonism, after idiopathic Parkinson's disease(IPD). DIP is frequently produced by antipsychotic drugs. But the clinical characteristics of DIP did not get attention by neurologist. So we studied the clinical profiles of DIP patients. METHODS: We studied the clinical profiles of thirthone patients who showed parkinsonism after antipsychotic drug treatment. We compared the score of motor part of the Unified Parkinson's Disease Rating Scale(UPDRS) between trihexyphenidyl(n=15) & amantadine(n=16) monotherapy group(initial & 4 week after treatment). RESULTS: The mean age of patients was 45 years. Bradykinesia was the 1st symptom in 26 patients(94%), tremor in 5 patients(6%). In 25 patients(81%), the first symptom appeared within 1 week after sntipsychotic treatment. There was a statistical significant negative correlation between the dosage of antipsychotic drug and the symptom-onset interval following treatment with antipsychotic drugs(simple correlation analysis, p>0.01). Bradykinesia and rigidity were appeared in all DIP patients, symmetric distribution was more common(94%, 87%) Tremor occurred in 27 patients (87%). In patients with tremor, postural or action tremor was dominant in 15 patients(56%) asymmetric distribution was more common(16/27, 59%). There are no statistical difference in motor score of UPDRS between trihexyphenidyl & amantadine monotherapy group(student t-test, p<0.05) CONCLUSIONS: Bradykinesia was the most common 1st symptom in DIP patients. Asymmertrical postural or action tremor was relativelly common in DIP. Amantadine showed the same efficacy in the treatment of DIP compared to anticholinergics.

Purpose:
Sinus tarsi syndrome (STS) is caused by various pathologies. However, the exact etiology of STS remains controversial. This study evaluated the imaging and arthroscopic findings of patients who underwent surgical treatment after conservative treatment for STS failed.
Materials and Methods:
Between December 2014 and August 2018, 20 patients (21 cases) who underwent surgical treatment for STS were included in the study. The clinical results were analyzed using the visual analog scale (VAS) and the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot functional scale. The radiographic results were analyzed using Meary’s angle, calcaneal pitch angle, and hindfoot alignment angle. The pathologic conditions of sinus tarsi were confirmed by magnetic resonance imaging (MRI) and subtalar arthroscopy. Synovitis, bone edema, and accessory anterolateral talar facet (AALTF) were evaluated on MRI. Synovial thickening, cartilage damage, interosseous talocalcaneal ligament (ITCL) and cervical ligament rupture, soft tissue impingement, AALTF, and accessory talar facet impingement (ATFI) were evaluated by subtalar arthroscopy.
Results:
The mean duration of symptoms was 28.7 months (4~120). All patients showed significant improvement in the VAS and AOFAS ankle-hindfoot scale. Significant improvements in hindfoot alignment angle and Meary’s angle postoperatively were noted in patients who underwent medial displacement calcaneal osteotomy. MRI confirmed synovitis in all patients, AALTF in 19 cases (90.5%), and ATFI with bone edema in seven cases (33.3%). In subtalar arthroscopy, pathologic conditions were observed in the following order:synovitis in 21 cases (100%), AALTF in 20 cases (95.2%), ITCL partial rupture in nine cases (42.9%), and soft tissue impingement in seven cases (33.3%). All cases had two or more pathological conditions, and 15 (71.4%) had three or more.
Conclusion
In cases of STS that do not respond to conservative treatment, a comprehensive examination of the lesions of the tarsal sinus and lesions around the subtalar joint is essential.

Different kinds of forces can be applied to the biological tissue. The analysis of the applied force is highly important to explain the mechanism of cellular response. In this study, the applied force to the collagen gel was analyzed by the finite elements analysis. The model received two different kinds of static force (compression and tension). The force range was 50g to 400g. In results, von Mises stress was concentrated in the peripheral region in the compression model. It was concentrated in the central area in the tension model. However, the compressive force was high in the peripheral area of the compression model and the tensional force was also high in the same area of the tension model. In conclusion, the applied force could be different to the region and it should be considered in the experiment to analyze the effects of the mechanical force on the cells.
