The anxiety disorders make up one of the most common groups of psychiatric disorders. Anxiety is an alerting signal ; it warns of impending danger and enables a person to take measures to deal with a threat. Three major schools of psychological theory-psychoanalytic, behavioral, and existential-have contributed theories about the causes of anxiety. Many drugs are effective in managing distressing signs and symptoms associated with anxiety disorders. As the symptoms are controlled by medication, patients are reassured and develop confidence that they will not be incapacitated by the disorder. Benzodiazepines are useful in panic disorder, phobias, and agitation. In general, benzodiazepines act as hypnotics at high doses and as anxiolytics or sedatives at low doses. The benzodiazepines have become the sedative-hypnotic drugs of first choice because they have a higher therapeutic index and significantly less abuse potential than do many of other sedative-hypnotics. The most common adverse effect of benzodiazepines is drowsiness. Some patients also experience dizziness and ataxia. The most serious adverse effects of benzodiazepines occur when other sedative substances are taken concurrently. When benzodiazepines are used for long periods, they usually cause significant tolerance, dependence, or withdrawal effects. Overdoses with benzodiazepines alone have a predictably favorable outcome. The benzodiazepines should be started at a low dosage, and the patient should be informed about the drug’s sedative properties and abuse potential. Serotonin-specific reuptake inhibitors (SSRIs) have a much more favorable profile of adverse effects and have significantly broadened the horizon for pharmacological treatment of anxiety disorder. Three fourths of patients experience no adverse effects at low starting doses, and doses may be increased relatively rapidly in these patients. In the remaining one fourth of patients, most of the SSRIs’ adverse effects appear within the first 1 to 2 weeks, and they generally subside or resolve spontaneously if the drugs are continued at the same dose.

PURPOSE: Chronic lung disease is a cause of significant morbidity and mortality in the neonatal respiratory distress syndrome. Although the exact mechanisms leading to the development of chronic lung disease are unknown, there is increasing evidence indicating that pulmonary inflammation contributes to the pathogenesis. The proinflammatory cytokines, interleukin(IL)-1beta, IL-8 may have a role to play in initiating the inflammatory response that is seen in chronic lung disease. In contrast, IL-10 is an antiinflammatory cytokine. The abnormal persistent inflammatory process in chronic lung disease may be due to dysregulation of these proinflammatory cytokines. So, to describe cytokine profiles of chronic lung disease in neonate, we analysed the IL-1beta, IL-8 and IL-10 levels in bronchoalveolar lavage fluid by ELISA technique. METHODS: We obtained bronchoalveolar lavage samples from 14 respiratory distress syndrome infants without chronic lung disease and 8 respiratory distress syndrome infants with chronic lungisease. The cytokine levels were assayed. RESULTS: The results were as follows: 1) IL-1beta levels were higher in chronic lung disease group(205.16+/-360.21pg/rnl) than group without chronic lung disease(21.21+/-26.14pg/ml)(P<0.05). 2) IL-8 levels were also higher in chronic lung disease group(166.16+/-347.26pg/ml) than group without chronic lung disease(49.85+/-105.27pg/ml)(P>0.05). 3) In contrast, IL-10 levels were lower in chronic lung disease group(78.29+/-138.69pg/ml) than group without chronic lung disease(111.29+/-155.27pg/ml)(P>0.05). CONCLUSION: These results suggest that the dysregulation of cytokines contributes to the pathogenesis of chronic lung disease. The difference in cytokine levels of bronchoalveolar lavage fluid can be used as a predictor for development of chronic lung disease.

4.Periciliary Epicanthoplasty.
Journal of the Korean Society of Aesthetic Plastic Surgery 2006;12(2):87-94
Visible scar is the most annoying problem in the surgical procedure to eliminate the medial epicanthal fold, which is a predominant feature among the Asian population. Many surgical techniques have been introduced since the early decades of the 20th century, but the scar problem still has been remained unsolved. If all the skin incision lines were located along the muco-cutaneous junctions and just below the eyelashes, resulting scars could be nearly invisible after 3 or 6 months postoperatively. I think periciliary epicanthoplasty will be the appropriate method to realize this concept perfectlly. From January 2002 to August 2006, 427 patients with medial epicanthal folds underwent epicanthoplasty using a periciliary Y-V advancement procedure in my office and most results have been proved scar free and natural. Surgical design of this procedure is very simple and acceptable to any type of epicanthal folds. Based on my own experiences I would like to offer some tip offs in performing this procedure together with surgical techniques and guidelines.

PURPOSE: The purpose of this study was to evaluate the effects of magnetization transfer contrast(MTC) andfat-suppression(FS) in variable spin-echo and gradient-echo sequences for articular cartilage imaging and todetermine the optimal pulse sequences. MATERIALS AND METHODS: Using variable 7-pulse sequences, the knees of 15pigs were imaged Axial images were obtained using proton density and T2-weighted spin-echo (PDWSE and T2WSE),turbo spin-echo (TSE), multiplanar gradient-echo (MPGR), and 3D steady-state gradient-echo (3DGRE) sequences, andthe same pulse sequences were then repeated using MTC. Also T1-weighted spin-echo(T1WSE) and 3D spoiledgradient-echo(3DSPGR) images of knees were also acquired, and the procedure was repeated using FS. For each knee,a total of 14 axial images were acquired, and using a 6-band scoring system, the visibility of and thevisibilities of the the articular cartilage was analyzed. The visual effect of MTC and FS was scored using a4-band scale. For each image, the signal intensities of articular cartilage, subchondral bone, muscles, and salinewere measured, and signal-to-noise ratios(SNR) and contrast-to-noise ratios(CNR) were also calculated. RESULTS: Visibility of the cartilage was best when 3DSPGR and T1WSE sequences were used. MTC imaging increased the negativecontrast between cartilage and saline, but FS imaging provided more positive contrast. CNR between cartilage andsaline was highest when using TSE with FS(-3 5 1 . 1 +/-15.3), though CNR between cartilage and bone then fell to-1 4 . 7 +/-10.8. In MTC imaging using MPGR showed the greatest increase of negative contrast between cartilage andsaline(CNR change=-74.7); the next highest was when 3DGRE was used(CNR change=-34.3). CNR between cartilage andbone was highest with MPGR(161.9 +/-17.7), but with MTC, the greatest CNR decrease(-81.8) was observed. Thegreatest CNR increase between cartilage and bone was noted in T1WSE with FS. In all scans, FS provided acartilage-only positive contrast image, though the absolute value of CNR was lower than that of MTC imaging. CONCLUSION: The most prominent effects of MTC and FS were seen in MPGR and T1WSE, respectively, though forcartilage, optimal high signal intensity and contrast can be achieved using 3DGRE with MTC, and 3DSPGR with FS.

BACKGROUND: Recent clinial observations have suggested that colchicine, which is in frequent use in gout can affect the conneciive tissue metabolism in skin and other ti.ues. OBJECTIVE: This study suggest that further development of colchiine might provide a novel means of modulating collagen gen expression in patients with fibrotic disease. METHOD: We examed the effect of colchicine on the expres, on of collagen, fibronectin and collagenase gene by skin filroblast culture hy Nort.hern and dot-blot iybridization. Result : The rate of transcription of genomic DNA corresponding o type I collagen and libvonectin was reduced in colchicine-treated cultures but collagenase was not. reduced. Canclusion : The microti.ikile disruptive agent, colchicine, reduced the expression of type I collagen and fibronectin in a dose-(lependent manner. This st.udy suppor that colchicine is one of the promising antifibrogenic drugs curvently being tested as a treatment, of hun an fibrotic disease.

This study was conducted to examine the effect of mefenamic acid for treatment of PDA in premature newborns. Ductus arteriosus is reopened by locally produced prostaglandin E2 in a premature newborn during hypoxia. Mefenamic acid is one of non-steroidal antiinflammatory drugs acting by inhibition of cyclo-oxygenase in the prostaglandin synthesis pathway. For three premature newborns with PDA, we administered mefenamic acid and evaluated them with echocardiography to study the effect of mefenmic acid for closure of PDA. In all three babies, ductus arteriosus was closed successfully. We feel that mefenamic acid is safe and effective medication for treatment of PDA in premature newborns, but further-study need to be conducted with larger numbers of cases to confirm this effect.
