Diabetic and nondiabetic vascular diseases cause significant foot problems and it frequently progress to osteomyelitis and amputation. Advances in vascular surgical techniques, including distal arterial bypass via synthetic grafts or autogenous vein grafting have opened the way for higher rate of limb salvage. We have experienced patients with ischemic vascular foot disease and combined skin ulceration and varing degree of soft tissue defect. In three patient with major vessel obstruction, we could preserve limb and avoid major amputation using greater saphenous vein graft with or without microvascular free tissue transfer.

The purpose of this study was to evaluate the influence of accessibility to dental cervices of maxillary molars upon plaque control level of these areas. Fifthy-seven dental students with healthy gingiae participated in this study. Maxillary dental casts were fabricated for each participants. Using the casts, cervical accessibility was measured at the mid-palatal point of maxillary first and second molars. Cervical accessibility was defined as the perpendicular distance from the entrance of gingival sulcus to the imaginary line between the most protruded points of palatal gingiva and tooth surface, and classified into degree I(< or =0.5mm), II(>0.5mm, < or =1.0mm), III(>1.0mm, < or =1.5mm), and IV(>1.5mm). Plaque score was recorded as the distance from crest of gingival margin to the most coronal extent of plaque. Measurements of plaque score were repeated 3 times at 1-week intervals. After the baseline measurements, the participants began to use unitufted brushes on randomly assigned right or left side. Two weeks later, a session of plaque score records identical to the baseline measurements was started. The maxillary second molars showed higher cervical accessibility than the first molars(p<0.01), but the plaque scores of maxillary second molars were also higher than those of first molars(p<0.01). For the maxillary first molars, correlation between accessibility and plaque score was statistically significant, but such correlation was not found for the second molars. Use of unitufted brushes decreased the plaque score(p<0.01). Correlation between accessibility and the degree of plaque score improvement was not found. These findings suggest that cervical accessibility may influence the amount of plaque, and use of adjunctive oral hygiene devices may be helpful in maintaining optimal oral hygiene level at the areas of low cervical accessibility.

BACKGROUND: Many factors affecting the spread of spinal anesthesia have been investigated. But L3-4 or L4-5 interspace was choosen which was known as the site of buffering, in their study. We investigated the effect of some of these factors on sensory blockade level by using L2-3 interspace. METHODS: Eightyfive patients, ASA physical status I - Il, were involved in our study. Sensory blockade level was checked with pinprick test at 10 minutes and 30 minutes. The effect of age, sex, height, weight, CSF pressure and pressure difference generated when full flexed and non-full flexed lateral position on sensory blockade level was studied whereas other factors such as puncture technique, dosage and concentration of drug and patients position after injection, were kept constant under the same condition. And also studied the effect of degree of flexion at injection on the sensory blockade level. RESULTS: Height and CSF pressure were correlated with sensory blockade level at 10 minutes after injection(R2=0.14, P<0.01). Only height was correlated with sensory blockade level at 30 minutes after injection(R2=0.09, P<0.0l). CONCLUSIONS: Only height was correlated with sensory blokade level at 30 minutes. So, height might be considered as the most impressive minor factor affecting the extent of sensory blockade level.

BACKGROUND: Temporary occlusion of hepatic blood inflow and vascular exclusion are effective for reduction of intraoperative bleeding which is a major problem during hepatic resection. But it might be suggested that they resulted in hemodynamic, electrolyte and blood gas changes. This study was designed for investigating those changes during liver resection using portal triad clamping and/or right, left or both hepatic vein clamping. METHODS: Forty one patients, diagnosed as hepatoma and intrahepatic duct stone, were involved in this study. Duration of liver ischemia was 48.7+/-14.8 min. Hemodynamic variables, electrolytes and arterial blood gas were measured before portal triad clamping and at 10, 30 min after clamping, and 10, 30, and 120 min after declamping, and were compared with each other. Bicarbonate was given when its value was below 20 mEq/L. RESULTS: In the changes of hemodynamics, diastolic blood pressure was decreased significantly at 10 and 30 min after declamping compared with before clamping. In the changes of ABG and electrolytes, pH, bicarbonate and chloride ion were changed significantly at 10 min after clamping compared with before clamping. pH at 10 min after declamping was decreased more associated with increasing anion gap without change of the bicarbonate and increased PaCO2. CONCLUSION: From these results, hemodynamic changes are not remarkable but metabolic acidosis is occurred from 10 minutes after portal triad clamping and more acidotic change was developed at 10 min after declamping, immediate treatment of metabolic acidosis is needed.

OBJECTIVE: The purpose of this study was to examine the pharmacological treatment patterns and clinical responses in inpatients and/or outpatients with obsessive compulsive disorder (OCD) at a university hospital. METHODS: A total of 71 OCD patients were included and followed during the first 4 months, first year and second year from 1998. The patterns of medication use and clinical responses according to the Yale-Brown obsessive-compulsive scale (Y-BOCS) were analyzed descriptively in this period. RESULTS: During the first 4 months, 26.7% of the patients underwent monotherapy in which most of the drugs were serotonin reuptake inhibitors (SRIs). Therapy with two or more drugs was administered in 66.6% of the patients and combination drugs with SRIs were atypical antipsychotics and clonazepam. The clinical response rate using Y-BOCS was 24.0% compared with baseline score. During the first year, the frequency of the monotherapy decreased to 6.5%, while that of therapy with two or more drugs increased to 80.6% (two and three drug frequencies were 35.3%, and 32.3%, respectively). The clinical response rate was 26.4% during this period. During the second year, the frequency of the monotherapy was 25% and that of multidrug therapy was 70.8% (two and three drug frequencies were 20.8%, and 45.8%, respectively). The clinical response rate was 39.3% compared with baseline score. CONCLUSIONS: In this study, the frequency of the combination therapy was relatively high compared with SRI monotherapy during the first 4 months and it increased further during the first year. The combination therapy was maintained without change of SRI dosage during the second year. Most of the drugs used in the combination therapy were atypical antipsychotics and clonazepam.

OBJECTIVES: The aim of this study was to investigate medium- and long-term developmental directions of mental hospitals. METHODS: The preliminary investigation is composed of unstructured interviews with 10 psychiatrists, literature and case investigations, and development of models for medium- and long-term developmental model. The qualitative investigation consisted of constructed interviews with seven professionals. The quantitative investigation was conducted using questionnaires, which were sent to members of the Korean Neuropsychiatric Association, etc. Data were analyzed using frequency analysis. RESULTS: Through the preliminary investigation we were able to make three models : community model emphasizing linkage between mental hospitals and community, specialization model stressing specializations of mental hospitals, and extension model highlighting extensions of the roles of the mental hospital. In the qualitative investigation, two of the seven professionals gave a special preference for the community model, one for the specialization model, and two for the extension model. In the quantitative investigation, the community model and the specialization model were the most favorite models, and the extension model was the least favorite model. CONCLUSION: Three developmental models could be used in planning of the medium- and long-term developmental directions of mental hospitals, although each model needs to be embodied in order to work in practice.

OBJECTIVES: The traditional roles of psychiatrists are being threatened according to the changes of requests from society. Psychiatrists need to rapidly adapt to new upcoming circumstances, improve leadership skills, and prepare for emerging ethical problems. The aim of this study is to predict and suggest what will happen in the future in the area of mental health, what role models might be required, what we should do and how we can prepare. METHODS: The authors interviewed seven mental health professionals on topics of leadership, participating roles of psychiatrists. Three models for psychiatrists were suggested : clinical model, community leader model, and mental health promoting model. Afterwards, a questionnaire on each role model was distributed to members of the Korean Neuropsychiatric Association via email and results were analyzed. RESULTS: Experts and stakeholders suggested that the following components from the interview will be fostered in the future : leadership in collaboration with other communities, introduction of leadership programs for young psychiatrists, strategies for sensitization of ethical issues, active communication with community partners, training professionals in legislation and administration. Regarding the questionnaire, 32 members responded. The most preferred role model was the Community leader model (46.9%, n=15), followed by the mental health promoting model (34.4%, n=11) and clinical model (15.6%, n=5). Most responders recognized that these issues are emerging and answered affirmatively on the developmental potential of each role model. A question about primary agents who are supposed to take charge of development of a suitable model was answered as follows : university professors for the clinical model (37.5%, n=12), psychiatrists working for public hospitals both for community leader (28.1%, n=9), and mental health promoting model (43.8%, n=14). Various opinions on leadership and strategies for fulfilling the role model were proposed. CONCLUSION: This study investigated leadership, ethics, social roles, and future directions of psychiatrists in order to provide suggestions on how to properly respond to changes of environment. It is expected that this study will be helpful in establishment of guidelines for leadership development and improving ethical orientation of psychiatrists, and will provide an opportunity for Korean NeuroPsychiatric Association members to have deep consideration and radical debate on our transforming roles.

An interscalene block for shoulder surgery provides excellent surgical conditions and is well received by patients. However, a combination of the sitting position, regional anesthesia, an awake patient, and a surgical procedure can result in another side effect, vasovagal episodes, which may lead to cardiac arrest in extreme cases. We experienced a case of 32-year-old male patient with a severe vasovagal episode that led to asystolic cardiac arrest 15 minutes after the changing to the sitting position under an interscalene block for shoulder arthroscopic surgery.
