New antidepressants have become available for clinical use in the 1990s. Before this decade, the drugs available to treat depression consisted essentially of monoamine oxidase inhibitors, tricyclic antidepressants, and lithium. Following the introduction of SSRIs, the options have expanded and now include SSRIs nefazodone, venlafaxine, mirtazapine, reboxetine, tianeptine. Newer antidepressants possess a variety of pharmacological characteristics that are relevant to the choice of an antidepressant for clinical use. This review summarizes some of the major pharmacological characteristics among the drugs.

The genetically determined CYP2D6 activity may be considered to be associated with antipsychotic induced extrapyramidal side effects with inter-individual variation. Genetic polymorphism of CYP2D6 was determined by polymerase chain reaction(PCR) and Mspl restriction fragment length polymorphisms(RFLP) for 194 schizophrenics. Subjects with a 334bp band were classified a1a1, those with 229bp and 105bp bands a2a2, and those with all three bands a1a2. We did not identify schizophrenic subject with poor metabolizer. 194 schizophrenic patients previously treated neuroleptic medication, were assessed by Extrapyramidal Symptom Rating Scale(ESRS). The cases were composed of 33 akathisia, 47 parkinsonism, 21 tardive dyskinesia. These results are similar to the previous understanding that the poor metabolizer is very rare in Orientals compared to Caucasians, therefore, it considered that CYP2D6 genotypes have maybe no association with schizophrenia and extrapyramidal side effects in Koreans.

PURPOSE: Recently, two tests are commercially available for the identification of latent tuberculosis infection (LTBI): tuberculin skin test (TST) and interferon-gamma release assay (IGRA). Due to its false positiveness, TST tends to be preferred by IGRA until now. In our study, we simultaneously performed both TST and QuantiFERON(R)-TB Gold In-Tube (QFT-GIT) and compared their results. METHODS: TST and QFT-GIT were done for the diagnosis of LTBI among children who visited pediatric out-patient clinic at St. Vincent's Hospital, The Catholic University of Korea from February of 2007 to May of 2008. The study group was stratified into two groups in terms of whether there was intrafamilial contact or not. RESULTS: Out of total 35 children, 29 were tuberculosis (TB)-exposed cases and the remainders were diagnosed as clinical pulmonary TB. Among these 29 children, TST was positive 38.9% (7/18) for the intrafamilial and 45.5% (5/11) for the non-intrafamilial, and at the same time, the result for QFT-GIT was positive 5.6% (1/18) and 9.1% (1/11), respectively which implies that TST was more sensitive than QFT-GIT. Among 29 TB-exposed cases, 26 initially went through TST and QFT-GIT together on their first visit to out-patient clinic, and 15 continued the follow-up tests. Out of total 41 cases collected, the agreement (known as kappa value) was 0.063 which was relatively low. Including 6 cases with pulmonary TB who were all positive for TST and only 5 being positive for QFT-GIT, the final kappa value was 0.334. CONCLUSION: In our study, the agreement for TST and QFT-GIT was low, and the majorities were almost the cases of positive TST. In current situation with lacking a gold standard test and limited data on children to adolescents, this result is quite alarming that the recent trend tends to replace TST by QFT-GIT when diagnosing LTBI.

The 5-HT2A receptor is of great interest for research into schizophrenia and psychopharmacology in light of the observation that schizophrenic patients has 5-HT cortical-subcortical imbalance and atypical antipsychotic clozpine has 5-HT2A antagonists properties. An significant association between schizophrenia and the T102C polymorphism of the gene for 5-HT2A receptor has been reported. In this study, we investigated an association between schizophrenia and the T102C polymorphism of the gene for 5-HT2A receptor in Korean schizophrenic patients. The subjects consisted of 139 schizophrenic patients and 88 normal controls. Genomic DNA was amplified by PCR and digested with MsPI. The uncutt product identified allele 1(nucleotide sequence TCT) ; digested products of 216bp and 156bp identified allele 2(nucleotide sequence TCC). The allele frequencies and the genotypic distribution of 5-HT2A receptor gene were not significantly different between schizophrenic patients and normal controls. Since allele frequencies of the T102C polymorphism may differ between individuals of different ethnic backgrounds, it needs to be conducted in an advanced research.

Hemiplegic gait is characterized by slow and poorly coordinated movements of the affected limb resulting from foot drop or equinus deformities. Ankle-foot orthoses(AFO) are frequently prescribed to improve the gait pattern of hemiplegics. Plastic AFO with different trimlines in controlling ankle motion can cause variable biomechanical effects. In this study, we analysed the biomechanical effect of donning AFO on hemiplegic gait and assessed whether any differences resulted when the AFO was modified. Gait events, plantar pressure, foot contact and centers of pressure(COP) parameters were measured with F-scan pressure sensitive insole system in 21 hemiplegic stroke patients with Brunnstrom's lower extremity stage 3. And those parameters were compaired in each of four different conditions: 1) before donning AFO, 2) donning AFO without any modification, 3) donning AFO with the dis tal part of metatarsal head trimmed off, 4) donning AFO with third condition and weaning a cushioned heel shoes. After donning AFO, total contact area and contact width were increased, and initial contact COP and mean COP were displaced medially. But contact length was not changed and initial contact COP and mean COP were not displaced anteroposteriorly. Anteroposterior displacement of COP, slope and velocity of COP were not also changed after donning AFO. Among various AFO adjustments, there were no significant changes of plantar pressure, foot contact and COP parameters. The results suggest that 1) AFO provides mediolateral stability, but does not provide additional functional rocker actions during stance phase and 2) There were no definite different biomechanical actions among various adjustments of plastic AFO in hemiplegic gait of Brunnstrom's lower extremity stage 3.

Open carpal tunnel release has been the standard method of sumical treatment of carpal tunnel syndrome. Recently endoscopic carpal tunnel release has been introduced and is heing used by many authors. The advantages of this new technique are less postoperative pain, rapid restoration of power and rapid return-to-work. However many considerate authors, in spite of these advantages. insist that the inevitahle risk of neurovascular injury during the endoscopic procedure should not he underestimated. The purpose of our study is to compare the clinical results of endoscopic carpal tunnel release with those of open release. 20 open carpal tunnel releases in 16 patients and 15 endoscopic carpal tunnel reieases (single-portal technique) in 11 patients were performed hy the first author. Preoperative conditions of both groups are not different. Authors compared the clinical results between the two groups with some parameters. The overall clinical results were not different significantly hetween two groups. Rapid return-to-work(36 days in endoscopic group versus 60 days in open group) and less postoperative scar and pillar pain in endoscopic group were demonstrated. However, the major complication of one median nerve injury in endoscopic group seemed to overweigh these some benefits. We suggest that the standard operative technique for carpal tunnel syndrome should be open carpal tunnel release and more considerations should be takcn in choosing endoscopic method because of its inherent risk.
