Positron emission tomography (PET) with 2-[F-18]-Fluoro-2-deoxy-D-glucose (FDG) was performed in ninteen patients who had benign musculoskeletal tumors in order to determine if there was a relationship between histologic grade of tumor and FDG uptake of tumor. These patients had been evaluated previously with computed tomography (CT) or magnetic resonance (MR) imaging or both. The diagnoses were confirmed with incisional or excisional biopsy or by radiographic follow-up. Generally high-grade tumors had significantly greater uptake of FDG than low-grade lesions . Benign lesions such as giant cell tumor, fibrous dysplasia, and osteofibrous dysplasia showed significant elevation of SUV (Standardized Uptake Value) above 4.0. On the contrary. The current studies suggest the utility of FDG-PET imaging as an adjunct to CT or MR imaging in the evaluation of benign tumors. And results of PET suggest benign tumors with high SUV are histologically active lesion and tend to be locally aggressive.

BACKGROUND: To evaluate depressure effect and safety of delapril, a new ACE inhibitor, in Korea. METHOD: Thirty three patients, aged 37-69, with mild to moderate essential hypertension were first observed for 2 weeks with placebo followed by administration of 15mg of delapril twice daily for 2 weeks, then doubled dosage to 30mg b.i.d. and combined with 25mg of dihydrochlorothiazide if optimal BP were not obtained at the end of 4th week, continued the same dose until the end of 10 week's trial period. RESULT: BP dropped 15/9mmHg inaverage at the end of 10th week rewarding 70% of cumulative effectiveness. Most frequent side reaction was dry cough, occurred in 9% of patients followed by chest tightness, headache, constipation and transient elevation of GPT. CONCLUSION: Delapril 15-30mg twice daily as monotheraphy or combined with diuretics is well tolerated and effective in the treatment of mild to moderate essential hypertension.

BACKGROUND: Spinal cord ischemic injury during thoracic and thoracoabdominal aortic surgeries remains a potentially devastating outcome despite using various methods of protection. Neuronal voltage-dependent sodium channel antagonists are known to provide neuroprotection in cerebral ischemic models. This study was designed to compare the neuroprotective effects of phenytoin with those of hypothermia in a rabbit model of spinal cord ischemia. MATERIAL AND METHOD: Spinal cord ischemia was induced in New Zealand white rabbits by means of infrarenal aortic cross clamping for 25 minutes. Four groups of 8 animals each were studied. The control group and the hypothermia group received retrograde infusion of saline only (22degrees C, 2 mL/min); the normothermic phenytoin group and the hypothermicphenytoin group received retrograde infusion of 100 mg of phenytoin at different rectal temperatures (39degrees C and 37degrees C, respectively) during the ischemic period. The neurologic function was assessed at 24 and 72 hours after the operation with using the modified Tarlov criteria. The spinal cords were harvested after the final neurologic examination for histopathological examination to objectively quantify the amount of neuronal damage. RESULT: No major adverse effects were observed with the retrograde phenytoin infusion during the aortic ischemic period. All the control rabbits became severely paraplegic. Both the phenytoin group and the hypothermia group had a better neurological status than did the control group (p<0.05). The typical morphological changes that are characteristic of neuronal necrosis in the gray matter of the control animals were demonstrated by means of the histopathological examination, whereas phenytoin or hypothermia prevented or attenuated these necrotic phenomena (p<0.05). The number of motor neuron cells positive for TUNEL staining was significantly reduced, to a similar extent, in the rabbits treated with phenytoin or hypothermia. Phenytoin and hypothermia had some additive neuroprotective effect, but there was no statistical significance between the two on the neurological and histopathological analysis. CONCLUSION: The neurological and histopathological analysis consistently demonstrated that both phenytoin and hypothermia may afford significant spinal cord protection to a similar extent during spinal cord ischemia in rabbits, although no significant additive effects were noticed.

Cryptococcus is native to the environment and thrives in any type of environment inhabited by birds. Cryptococcal genito-urinary infection has been reported in immunnocompromised patients and can involve the adrenal gland, kidney, prostate, or penis. To our knowledge, there have been no reports of cases where cryptococcal epididymo-orchitis infects an uncompromised healthy host. Here, we report a case of primary cryptococcal epididymo-orchitis in a healthy male.

Impetigo herpetiformis is a rare pustular eruption that may be seen in late pregnancy. It is associated with severe maternal and fetal complications in case of misdiagnosis and delayed treatment. The patient was a 25-years-old multigravida with psoriasis in her past history. At 20weeks gestation, she had been developed erythematous scaly annular patchs with papules and pustules on inner thigh. At 37weeks' gestation, the patient was suffered from a severely pruritic pustular rash with fever and leukocytosis. The skin of the affected areas was biopsied and showed intraepidermal pustular abscess with a neutrophilic infiltrate. Treatment commenced with intravenous fluids, antibiotics, systemic prednisone, steroid creams, and phototherapy(UVB) under the careful fetal well being monitoring. Cesarean section was done due to fetal distress, and a normal healthy male infant was delivered, following which the patient's condition improved rapidly.

8.A Case of the Pneumopericardium Following Blunt Chest Trauma.
The Korean Journal of Thoracic and Cardiovascular Surgery 2003;36(8):627-629
The pneumopericardium following blunt chest trauma is exceedingly unusual. A patient was admitted to the emergency room after a motorcycle accident. Pneumopericardium and left pneumothorax were not detected on initial chest AP, but they were detected on chest computed tomograpy and resolved completely after chest tube insertion into the left pleural space.

PURPOSE: To determine whether prostate-specific antigen density(PSAD) and transition zone prostate-specific antigen density(TZ-PSAD) can predict the clinical response of patients with benign prostatic hyperplasia(BPH) to alpha-adrenergic blocker(terazosin). MATERIALS AND METHODS: From January 2000 to June 2002, 202 patients with BPH who were treated with alpha-adrenergic blocker(terazosin) were enrolled in this study. The peak flow rate(Qmax) and the International Prostate Symptom Score(IPSS) were compared prior to and 3 months following medication. We analyzed total prostate volume(TPV), transition zone volume(TZV), transition zone index(transition zone volume/total prostate volume, TZI), PSAD(PSA/total prostate volume), and TZ-PSAD (PSA/transition zone volume) as predictors of the response to alpha-adrenergic blocker (terazosin). RESULTS: At 3 months following medication with terazosin, a statistically significant improvement was shown in the IPSS and Qmax. There was no significant correlation between pretreatment TPV, TZV, TZI and the percent change in the IPSS and Qmax. However, there was a significant negative correlation between pretreatment PSAD (r=-0.632, p<0.001), TZ-PSAD (r=-0.599, p<0.001) and the percentage change in Qmax, while there was a positive correlation between pretreatment PSAD (r=0.620, p<0.001), TZ-PSAD(r=0.604, p<0.001) and the percentage change in the IPSS. Using the receiver operating characteristic curves to compare PSAD and TZ-PSAD for IPSS, the areas under the respective curves were 0.867 and 0.874(cut-off values were 0.04 and 0.1), and for the Qmax, the areas under the respective curves were 0.876 and 0.873(cut-off values were 0.04 and 0.1). CONCLUSIONS: Patients with a lower pretreatment PSAD and TZ-PSAD responded better to alpha-adrenergic blocker than those with a higher pretreatment PSAD and TZ-PSAD. PSAD and TZ-PSAD were predictors of the response to alpha-adrenergic blocker (terazosin) in patients with BPH.

The Korean Journal of Thoracic and Cardiovascular Surgery 1998;31(10):945-951
BACKGROUND: Although profound hypothermia with total circulatory arrest (TCA) is a valuable maneuver in cardiac surgery, its applications have been limited due to serious complications, especially cerebral damage. In this study, the possible role of creatinine kinase-BB (CK-BB), an index enzyme of ischemic cerebral damage, was assayed as a parameter for the assessment of the cerebral complications after TCA. Hemoglobin (Hb), ionized calcium (Ca++), and blood glucose levels were also assessed as clinical parameters involved in cerebral damage. MATERIALS AND METHODS: Among patients with congenital heart disease, 18 patients who had been operated on with TCA were randomly selected and divided into two groups: 6 with acyanotic and 12 with cyanotic heart disease. Arterial blood from each patient was collected before and after TCA at scheduled times (15 min., 30 min, 1, 2, 4, 8, and 12hr). The levels of CK-BB, Hb, Ca++, and blood glucose were assessed in each sample. RESULTS: As a whole, correlation between CK-BB level and blood sampling time after TCA was not statistically significant. Also, the difference in the level of CK-BB after TCA was not significant between the acyanotic and cyanotic groups. The levels of Hb and CK-BB correlated significantly. CONCLUSIONS: The results, which showed no correlation between the alterations in CK-BB level and the TCA duration, suggest that the single assay of the CK-BB level is not a representative measurement for the assessment of cerebral damage after TCA. Also, the cyanotic congenital heart disease group is not more vulnerable to cerebral damage induced by TCA.
