In periodontics, much progress was made in the understanding of periodontal disease from 1960s to 1980s and in prevention and management of periodontal disease since the end of 1980s. This presentation will discuss about the prevalence of periodontal disease, treatment need, and provision of periodontal treatment in Korea, and how we could manage the periodontal disease efficiently in the future. According to an epidemiological study in Korea, periodontal disease(including gingivitis) was present in 82% of general population and periodontitis in 30-40% in adult population over 30y and juvenile periodontitis in 0.1% of adolescents. If we consider that at least 17% of these patients may have recurrent or refractory forms, there is obviously an abundance of disease that needs treatment. As a result of increase in life expectancy, senile population over 65 y will be increased from 6% in 1996 to 6.9% in 2000, and tooth retention rate and periodontal treatment need are expected to increase. Periodontists need all the help they can get from the general dentists to control periodontal disease. As for provision, postgraduate course in periodontics started in 1957 in Korea and produced over 700 specialized dentists in periodontics. One report indicated that the periodontists as well as general practitioners did periodontal therapy on only a few periodontal patients, because of specific control by current medical insurance system in Korea. Comprehensive periodontal examination is rarely done in local dental clinic. Therefore, enhancement of periodontal care in medical insurance system and education of simplified periodontal examination such as Periodontal Screening & Recording will make dentists diagnose and manage the management of adult patients is based on the recognition that there are multiple diseases, including gingivitis, chronic adlt periodontitis, and other more aggressive forms of periodontitis, and requires the earliest possible recognition of these three disease categories. In this presentation, we discuss practical approach using PSR to diagnose, manage and refer the patients, to facilitate the separation of the simple from the complex and the predictable from the unpredictable form of periodontal diseases and to integrate diagnostic and therapeutic techniques into private practice today.

Cerebral venous thrombosis is come from thromboplebitis of infectious origin and bland occlusion of cerebral vein by various causes. Although the main cause of cerebral venous thrombosis is thrombophlebitis, the bland occlusion causes it infrequently as a form of an infarct state. We report a case of cerebral venous infarction caused by splenectomy induced thrombocytosis.

In order to observe the arrhythmia which occured in early convalescent phase of acute myocardial infarction, a 24 hour ambulartory ECG monitiring was performed in 15 patients who is admitted at dept of Int Medicine, Ewha Womans University hospital from Aug. 1985 to Sept. 1986. during 7.5+/-3.4 days after admission. In all cases one or more of the following arrhythmias were observed;atrial premature beat, ventricular premature beat(VPB), transient paroxysmal ventricular thchycardia, atrial fibrillation, sinus arrest and junctional beat. Of 15 cases, 11(77.3%) had VPB's:Simple VPB's in 4 cases(26.7%) and complex VPB's(6.52+/-2.52)(P<0.05). But there were no difference of premature and abberancy index between complex VPB's and simple VPB's(P>0.1). In addition, we compaired the arrhythmias in CCU with those of early convalescent phase of acute myocardial infarction. But there was no correlation between them.

Angiokeratoma circumscriptum is present at birth or early childhood and is an uncommon dermatosis characterized by papules and small nodules that may coalesce to form plaques. Histopathologically, there are varying degrees of hyperkeratosis, papillomatosis, and irregular acanthosis. In the papillary dermis, greatly dilated capillaries are observed, The acanthotic epidermis encircles the vascular spaces(blood cysts) where, occasionally, organized thrombi may be found. The use of pulsed-dye lasers to treat cutaneous vascular lesions is based on the theory of selective photothermolysis. We report a case of an angiokeratoma circumscriptum in an 48-year-old woman for whom the flashlamp pulsed tunable dye laser proved to be a highly successful means of treatment.

To evaluate the effect of Morphine during spinal anesthesia with alpha-adrenergic agonist, we used 0.18 mg of epinephrine, 90 ug of clonidine and 0.3 mg of morphine with 12 mg of T-cain respectively and compared hemodynamic and analgesic effects of each drug. Eighty patients were divided into four groups as follows; Group I (n=20); T-cain with clonidine, Group II (n=20); T-cain with epinephrine, Group III (n=20); T-cain with clonidine and morphine, and Group IV (n=20); T-cain with epinephrine and morphine. The results were as follows; 1) The onset time of analgesia and the time reached to the highest level of sensory loss were most rapid in the epinephrine and morphine group. 2) The duration of analgesia was significantly prolonged in the group of epinephrine and morphine than the group of epinephrine and clonidine. 3) It was more likely complicated in the morphine groups than others but there was no significance. 4) Although the heart rate was gradually decreased over 60 min. after anesthesia, there was no significance between the groups. 5) Systolic and diastolic blood pressure were decreased mainly over 30~45 min. after anesthesia, but there was no significance. In conclusion, epinephrine can be sustituted for clonidine because analgesic duration was not significantly changed, and the duration of analgesia was prolonged by morphine.

BACKGROUND: Acute drug intoxication has recently become an important issue in the social and clinical areas. There are various complications associated with acute drug intoxication such as pneumonia, but the process is was not fully understood. The aim of this study was to analyze our cases of pneumonia associated with acute drug intoxication and to determine the associated risk factors. METHOD: Forty four cases out of 237 patients, who were acute drug intoxicated from May 2000 to Feb. 2005, were diagnosed with pneumonia at the Konyang University hospital. These cases were analyzed by a retrospective review of their medical records. RESULTS: The incidence of pneumonia in acute drug intoxication was 18.6%. There was no gender difference in terms of the incidence, but the age group with the highest incidence was in the 5th decade (22.5%) followed by the 7th decade (17.9%). Most common drug of associated with pneumonia was organophosphate insecticides, and the others were herbicides. Suicidal attempts were the most common motive of intoxication. The incidence of pneumonia was increased in old age (beta=0.128, p<0.05). A drowsy or comatous mental status was an independent risk factors of pneumonia (beta=-0.209, p=0.006). A longer hospital duration was also a risk factor for pneumonia (beta=0.361, p<0.001). The intubated state, intensive care unit care and longer duration of admission correlated with the course of pneumonia in acute drug intoxicated patients (p<0.05). The culture study revealed MRSA to be most common pathogen. CONCLUSION: The incidence of pneumonia associated with acute drug intoxication was higher in the older aged patients, those with a decreased initial mental status and a longer hospital duration. The number of days in the intensive care unit and intubation were associated prognostic factors for pneumonia in acute drug intoxication patients.

PURPOSE: This study was conducted to perform a comparative analysis of the efficacy and safety of photoselective vaporization of the prostate (PVP) for treatment of benign prostatic hyperplasia (BPH) in men with a prostate volume greater than 60 cc. MATERIALS AND METHODS: The clinical data of 249 men with symptomatic BPH who underwent PVP between January 2006 and June 2008 were retrospectively analyzed. All patients were classified into two groups according to their prostate volume (group A, <60 cc; group B, > or =60 cc). The preoperative evaluation included a digital rectal exam, urinalysis, prostate-specific antigen levels, International Prostate Symptom Score (IPSS), quality of life (QoL) score, maximal flow rate (Qmax), postvoid residual urine volume (PVR), and transrectal ultrasonography. The total operative time, used energy (kJ), urethral Foley catheter indwelling period, and the number of hospital days were recorded afterward. The IPSS, QoL score, Qmax, and PVR were evaluated at 1, 3, 6, and 12 months postoperatively. RESULTS: In both groups, significant improvements in the subjective and objective voiding parameters were achieved and these improvements were sustainable for at least 1 year with minimal complications. During the follow-up period, the PVR in group B significantly increased. Retrograde ejaculation and urethral stricture were the common complications in both groups. There was no significant difference in the incidence rate. CONCLUSIONS: PVP is safe and efficacious, with durable results for men with symptomatic BPH and large prostate volumes.

PURPOSE: To evaluate high-resolution CT(HRCT) findings of the miliary tuberculosis and their significancy. MATERIAL AND METHOD: We retrospectively studied clinical records, HRCT and chest radiographs of 14 patients with miliary tuberculosis. RESULTS: On HRCT, nodules were seen in all 14 cases, 10 of them evenly, and 4 were irregularly distributed. The size of each nodule was less than 1 mm in 7 cases, 1 --2ram in 6 cases, and 3mm or more in 1 case. The ground - glass opacity was accompanied in 8 cases, and fine reticular opacity was also noted in 8 cases. Other associated findings were pleural effusion (n=4), hilar and mediastinal lymphadenopathy (n=3), consolidation of the exudative tuberculosis (n=4). CONCLUSION: HRCT findings of miliary tuberculosis are diffusely distributed micronodules of variable size, less than 5mm in diameter. The ground-glass opacity can be combined.
