OBJECTIVES: The present study aimed to improve understanding and treatment of pathological gambling by comparing levels of stress, coping styles, depression, 'Gambling attitudes and Beliefs' in pathological gamblers to groups of non-pathological gambling controls. METHODS: Pathological gambling was measured by the South Oaks Gambling Scale, depression by the Beck Depression Inventory, stress by Daily Hassles Scales, attitude and belief about gambling by the Gambling Attitude and Belief Scale and coping styles by Problem-focused Styles of Coping Inventory. RESULTS: Pathological gamblers reported significantly higher level of stress, depression, the Gambling Attitude and Belief, craving and more maladaptive styles of coping (reactive and suppressive) than control groups. Pathological gambler's use of maladaptive coping was disappeared when depression was controlled. CONCLUSION: The results of this study suggest that pathological gambler's maladaptive styles of coping might close related to depression, and treatment which is designed to improve depression and their ability to engage in reflective coping when stressors arise will be helpful. Further longitudinal studies may clarify the ways in which pathological gambler's depression and coping styles interact over time.

BACKGROUND: Because specific chromosomal abnormalities are associated with certain hematologic disorders, cytogenetic studies can help classifing the diseases, providing the clues of disease progression and being used to monitor remission after chemotherapy. In this study, cytogenetic analysis was performed. In acute and chronic leukemic patients in Korea and the results were compared with foreign cytogenetic reports, and the typical acute lymphocytic leukemia (ALL) and acute myelocytic leukemia (AML) associated chromosome aberrations were analysed by some calculated parameters to clarify if the specific chromosomal abberations in the specific types or subtypes of leukemias had diagnostic value or not. METHOD: Chromosome studies were done in bone marrow or peripheral blood samples by high resolution banding technique. Sensitivity, specificity, and positive and negative predictive values of finding or not finding a given aberration were calculated for followings : for the differential diagnosis between ALL and AML when a patient is known to have acute leukemia, for the differential diagnosis among AML and ALL FAB subtypes in a patient with known AML and ALL. RESULTS: The high positive predictive values (1.0) in the AML versus ALL comparison were found for -7, del(7) (q11-34q22-36), +8s, t(8;21) (q22;q22), t(15;17) (q22;q11), inv (16) (q13;q22) and -Y. Among the AML subtypes, the highest sensitivity, positive and negative predictive values were 0.85, 0.97, 0.94 for t(15;17) (q22;q11) in M3, respectively. The high positive predictive values and specificity in the ALL versus AML comparison were found for t(1;19) (q23;p13) ,t(4;11) (q21 ;23) and t(8; 14) (q24;q32) Among the ALL subtypes, the highest negative predictive value was 0.99 for t (8;14) (q24;q32) in L3. Among 398 CML cases, Philadelphia chromosome positive CML were shown in 81.9% that were classic t(9;22) (q34;all) (94.5%), complex variant traslocation(1.8%) and additional secondary chromosome aberrations (3.7%) . CONCLUSION: Total chromosomal aberration rate in acute and chronic leukemia in Korea was lower than that in foreign reports, but the patterns of chromosome aberrations were similar except for t(15;17) (q22;q11) in AML patients. Quantitativly calculated data of sensitivity, specificity and positive and negative predictive values in the specific chromosomal aberration might be used for diagnostic markers of acute leukemia.

OBJECTIVES: This study was designed to evaluate the relationship between quality of life (QOL) and psycho-socio-spiritual characteristics in male patients with alcohol dependence. METHODS: The sample consisted of 109 men with alcohol dependence defined by DSM-IV criteria. We assessed QOL by the WHO QOL assessment instrument-BREF (WHOQOL) and SmithKline Beecham QOL (SBQOL). Sociodemographic and alcohol related data were collected, and 7 questionnaires were administered: MAST, BDI, STAI, Drinker Inventory of Consequences (DrInC), Scale of Social Support (SSS), Religious Beliefs and Behaviors (RBB) and Spiritual Well-being Scale (SWBS). The correlations between each QOL score and other variables were examined, and stepwise multiple regression analysis was performed. RESULTS: The WHOQOL score positively correlated with education level, SSS (support) and RBB and negatively correlated with MAST, DrInC, BDI, STAI (trait) and SSS (conflict) scores. In stepwise regression analysis, the scores on the STAI and BDI contributed to the score on the WHOQOL. The SBQOL score correlated with the income level, and negatively correlated with BDI and STAI score. STAI score was a weak predictor of SBQOL score. CONCLUSION: The significant predictors of QOL in patients with alcohol dependence were psychological factors such as anxiety and depression.

Intra-articular hyaluronic acid injections for symptomatic treatment of osteoarthritis are widely used but can result in complications, such as infectious arthritis. Staphylococcus lugdunensis is a common normal skin flora but can cause severe infectious disease, such as infective endocarditis. We present the first report of infectious arthritis caused by methicillin-sensitive S. lugdunensis after intra-articular hyaluronic acid injection in an immunocompromised patient in Korea.

Phytolaccae had been used as a pharmaceutical drug or food But nowadays, due to its toxicity, Phytolaccae is rarely used and cases of patients poisoned with it are seldom reported. The case presented here was of 43 year-old male who after ingesting extract of Phytolacca esculenta suffered from abdominal pain, diarrhea, nausea, vomiting, tachycardia, hypotension, pruritus, paresthesia, oliguria and azotemia. Kidney biopsy revealed tubular necrosis and some protein casts in tubular lumens. These findings suggested that acute renal failure was mainly caused by nephrotoxicity of Phytolacca extracts. Through continuous arteriovenous hemofiltration and two times of hemodialysis, he was completely recovered from acute renal failure. Other symptoms also disappeared by symptomatic management, but paresthesia of both lower extremities still remained. So we reported this case with a brief review of literature.

OBJECTIVE: New antidepressant, nefazodone is classified as a serotonin -2 antagonist/reuptake inhibitor like old antidepressant, trazodone. Nefazodone, however, differs from trazodone in that it lacks anti-histaminergic properties and in that it has some norepinephrine reuptake inhibitory properties. These differences may account for the differences between the two drugs in the side effect profiles. This study was conducted to compare the acute effects of nefazodone on the psychomotor performance with those of trazodone. METHODS: The subjects were 12 healthy male volunteers aged between 20-40 years. A single, oral starting dose of nefazodone or trazodone was administered in a double-blind, randomized latin-square design with a 1-week interval between each drug switch. Psychomotor performances were assessed at 1 hour before and at 2 hours after administration of nefazodone 50 mg, nefazodone 100 mg or trazodone 50 mg. The measures of psychomotor performance included Vienna Determination Unit for complex choice reaction time, Critical Flicker Fusion Test, and Grooved Pegboard Test. RESULTS: In the Vienna Determination Unit, when 'within drug effect' (pre- vs. post-medication) was analyzed, nefazodone 100 mg decreased complex choice reaction time in both subtest 2 and subtest 3. Nefazodone 50 mg also decreased the reaction time in subtest 3 but not in subtest 2 which was more difficult and demanding task than subtest 3. On the other hand, no significant changes in the reaction time were observed with trazodone 50 mg in either subtest 2 or subtest 3. When 'between drug effect' was analyzed, however, the differences between drugs were not found to reach statistically significant level. No significant 'between drug effect' or 'within drug effect' was observed in Critical Flicker Fusion Test and Grooved Pegboard Test. CONCLUSION: Although the differences between nefazodone and trazodone did not reach statistically significant level, the results on the complex choice reaction time suggest that al least a single starting dose of nefazodone up to 100 mg does not impair psychomotor performances and it might have a less detrimental effect than trazodone on the psychomotor performance.

Calcium channel blockers (CCBs) are very popular drugs to lower blood pressure (BP) without significant side effects. A 72-year-old man admitted for uncontrolled hypertension. He had history of hypertension, atrial fibrillation with slow ventricular response, angina, abdominal aortic aneurysm, and stage 3 chronic kidney disease. He had taken several anti-hypertensives, such as amlodipine 5 mg, perindopril 8 mg, and indepamide 1.5 mg. To control BP, nifedipine 120 mg was added. Then pulmonary edema and pleural effusion was developed. Echocardiography showed preserved left ventricular ejection fraction and mild mitral regurgitation. Fluid restriction and high dose furosemide did not cease pleural fluid accumulation. Thus a total of 4 times of thoracentesis were done and all fluid analyses revealed transudate. We thought that pleural effusion and pulmonary edema was induced by CCBs and discontinued the drugs. He recovered quickly and finally discharged in a stable condition.

OBJECTIVE: Shunt-dependent chronic hydrocephalus (SDCH) is known to be a major complication associated with aneurysmal subarachnoid hemorrhage (aSAH). Old age is known to be one of numerous factors related to the development of SDCH. This study investigated whether postoperative cisternal drainage affects the incidence of SDCH and clinical outcome in elderly patients with aSAH. METHODS: Fifty-nine patients participated in this study. All patients underwent aneurysmal clipping with cisternal cerebrospinal fluid (CSF) drainage. Clinical variables relevant to the study included age, sex, location of ruptured aneurysm, CT finding and clinical state on admission, clinical outcome, and CSF drainage. We first divided patients into two groups according to age (<70 years of age and > or =70 years of age) and compared the two groups. Secondly, we analyzed variables to find factors associated with SDCH in both groups (<70 years of age and > or =70 years of age). RESULTS: Of 59 patients, SDCH was observed in 20 patients (33.9 %), who underwent shunt placement for treatment of hydrocephalus. Forty seven percent of cases of acute hydrocephalus developed SDCH. In the elderly group (> or =70 years of age), the duration and amount of CSF drainage did not affect the development of chronic hydrocephalus. CONCLUSION: In elderly patients, although the incidence of SDCH was significantly higher, clinical outcome was acceptable. The duration and the amount of cisternal drainage did not seem to be related to subsequent development of chronic hydrocephalus within elderly patients aged 70 or older.

The purpose of this study was to evaluate cervical lymph node metastasis of oral squamous cell carcinoma patients by MRI film and neural network system. MATERIALS AND METHODS: The oral squamous cell carcinoma patients(21 patients, 59 lymph nodes) who have visited SNU hospital and been taken by MRI, were included in this study. Neck dissection operations were done and all of the cervical lymph nodes were confirmed with biopsy. In MR images, each lymph node were evaluated by using 6 MR imaging criteria(size, roundness, heterogeneity, rim enhancement, central necrosis, grouping) respectively. Positive predictive value, negative predictive value, and accuracy of each single MR imaging criteria were calculated. At neural network system, the layers of neural network system consisted of 10 input layer units, 10 hidden layer units and 1 output layer unit. 6 MR imaging criteria previously described and 4 MR imaging criteria (site I-node level 2, site II-other node level, shape I-oval, shape II-bean) were included for input layer units. The training files were made of 39 lymph nodes(24 metastatic lymph nodes, 10 non-metastatic lymph nodes) and the testing files were made of other 20 lymph nodes(10 metastatic lymph nodes, 10 non-metastatic lymph nodes). The neural network system was trained with training files and the output level (metastatic index) of testing files were acquired. Diagnosis from neural network was decided according to 4 different standard metastatic index-68, 78, 88, 98 respectively and positive predictive values, negative predictive values and accuracy of each standard metastatic index were calculated. RESULTS: In the diagnosis of using single MR imaging criteria, the rim enhancement criteria had the highest positive predictive value, 0.95 and the size criteria showed the highest at negative predictive value, 0.77. The highest accurate criteria was heterogeneity with the accuracy of 0.81 and the lowest one was central necrosis with accuracy of 0.59. In the diagnosis of using neural network systems, the highest accurate standard metastatic index was 78, and that time, the accuracy was 0.90. Neural network system was more accurate than any other single MR imaging criteria in evaluating cervical lymph node metastasis. CONCLUSION: Neural network system has been shown to be more useful than any other single MR imaging criteria. In future, Neural network system will be powerful aiding tool in evaluating cervical node metastasis.
