Modern medical oncology has introduced various anti-cancer drugs since the World War I and II. Unlike for the solid tumors, hematological malignancies had been documented some limitations for curing it with chemotherapeutic agents only. In 1960, Dr. Nowell and Dr. Hungerford had discovered elongated chromosome (Philadelphia chromosome) which has documented as a product of translocation between 9th and 22nd chromosome in the patients with chronic myeloid leukemia. In 1970s, immunochemistry technique using monoclonal antibody has spread world widely and from 1990s, flow cytometry method has been available. In appreciation of these evolutions in basic science, the treatment strategy ofhematological malignancies has changed from the chemotherapeutic agents to targeted agents. Among the targeted agents, some drugs are newly developed and others are recreated as anti-cancer drugs after long-time of discard because of their toxicities or teratogenic effects. Nowadays, we are in the middle of flood of targeted agents, for example, tyrosinekinase inhibitors, epidermal growth factor receptor blockers, farnesyl transferase inhibitors, histone deacetylase inhibitors, and etc. In 21st century, the optimal treatment of hematological malignancies should follow a tailor- made strategy according to the patient and disease itself. In the present article, some representative agents will be introduced in accordance with target diseases.

BACKGROUND: Epidural and intravenous (IV) administration of opioids are commonly used for postoperative pain management. However, studies that compare the epidural and IV routes of opiate administration show conflicting results. The purpose of this study was to determine the superior route of analgesics by comparing the effect of epidural fentanyl-bupivacaine with IV morphine using patient-controlled analgesia (PCA) system in the management of posterior thoracic surgery pain. METHODS: Sixty patients undergoing elective thoracic surgery were randomly assigned to receive either Epiural-PCA (Epi-PCA, n=30) or IV-PCA (n=30) when postoperative pain first increased to 40/100 mm (by visual analogue scale; VAS). Epi-PCA group received epidural bolus of 0.1% bupivacaine 10 ml containing fentanyl 100 microgram and then followed by Epi-PCA with 0.1% bupivacaine 100 ml containing fentanyl 800 microgram (basal infusion 2 ml/hr, PCA dose 1 ml, lock-out interval 30 min), IV-PCA group received repeated IV boluses of 3 mg of morphine until postoperative pain decreased to 40/100 mm and then followed by a IV-PCA with morphine (basal infusion 0.005 mg/kg/hr, PCA dose 0.02 mg/kg, lock-out interval 8 min). Analgesic efficacy, degree of patient satisfaction and pain, analgesics consumptions, forced vital capacity (FVC), forced expired volume in one second (FEV1) and side effects were evaluated. RESULTS: There were no significant differences in analgesic efficacy and degree of patient satisfaction and pain in both group. But the PHS were significantly lower (p<.05), and FEV1 higher (p<.05) in Epi-PCA group, signifying better analgesia during movement (cough and deep breaths). CONCLUSIONS: We concluded that an epidural PCA with mixture of fentanyl and bupivacaine administration is superior to that of intravenous PCA with morphine in the management of pain after thoracic surgery.

OBJECTIVES: Chronic pain is one of the most common experiences of humans and a typical psychophysiological disorder. The aim of this study was to measure the psychophysiological responses in chronic pain patients using a biofeedback system, and to compare them with the results from normal healthy subjects. METHODS: Forty two patients with chronic pain (17 males and 25 females, average age 44.67+/-11.10 years) and 42 normal healthy controls (17 males and 25 females, average age 45.17+/-10.46 years) participated in this study. Electromyography (EMG), skin conductance (SC), and skin temperature (ST) were recorded using biofeedback system during the 3 phases (baseline, stress, and recovery) of stress reactivity test, and average values of them were calculated. Difference of values between two groups in each corresponding phase was analyzed with independent t-test, and change of values across phases of stress reactivity test was analyzed with paired t-test (all two-tailed, p<0.05). RESULTS: Compared to normal controls, chronic pain patients had higher value of EMG (baseline : 8.10+/-5.97 micronV vs 4.72+/-1.52 micronV, t=-3.56, p<0.01 ; stress : 11.25+/-6.89 micronV vs 8.49+/-4.78 micronV, t=-2.13, p<0.05 ; recovery : 7.12+/-3.77 micronV vs 4.78+/-1.59 micronV, t= -3.70, p<0.01) and SC (baseline : 1.06+/-1.0 micronS vs 0.42+/-0.29 micronS, t=-4.0. p<0.01 ; stress : 1.87+/-2.05 micronS vs 1.03+/-0.86 micronS, t=-2.47, p<0.05 ; recovery : 1.74+/-1.77 micronS vs 0.64+/-0.59 micronS, t=-3.8, p<0.01) in all the 3 phases. But, skin temperature comparison did not reveal significant differences in all the 3 phases between two groups. CONCLUSION: Psychophysiological responses of chronic pain patients in stress reactivity test were different from those of normal healthy controls. These results suggest that sympathetic nervous system is more activated in chronic pain patients.

Since introduction of venous flap in 1980, many experimental studies and clinical applications of various kinds of venous flaps were reported. Venous flap has the following advantages : (1) nonbulky and goo-quality of flap (2) long & large vascular pedicle (3) easy & rapid elevation of flap (4) no sacrifice of major arteries (5) a single operative field. But, we also have some disadvantages of difficult handling of the pliable veins and the tmcertainty of flap survival. For the better result we had to design the size of the flap larger than that of defect and increase the number of draining vein to reduce the postoperative edema of the flap. We have treated the defects of soft tissue of the hand using free arterialized venous flap from the flexor aspect of the forearm & had an excellent results.

Inguinoscrotal bladder hernia is relatively common in obese males over 50 years old, especially patients with benign prostate hyperplasia. Various imaging modalities are used for diagnosis of inguinoscrotal bladder hernia. In particular, ultrasonography has many benefits, including non-invasiveness, and the fact that it does not require exposure to radiation; however, no domestic cases of ultrasonographic diagnosis of inguinoscrotal bladder hernia have been reported. The authors report on a case of a 67-year-old male patient with right scrotal swelling diagnosed as inguinoscrotal bladder hernia by ultrasonography, including three-dimensional imaging. Findings on ultrasonography showed a sacular lesion in the scrotum, which was connected to the urinary bladder through the inguinal canal; additional findings on CT, PET, and cystography showed that the entire lesion had a dumbbell shape.

Imipramine(Tofranil(R)) is one of the tricyclic antidepressants commonly used in depressive symptoms or enuresis. An accidental or nonaccidental poisoning of imipramine is common today. A 16 years old girl was admitted to Seoul National university Hospital because of unocnsciousness and frequent attacks of seizure after the impulsive ingestion of 1.4gm of imipramine. She showed variable arrhythmias such as complete RBBB, secod degree AV block and ventricular tachycardia and recovered from poisoning without residual myocardial damage. We present a case of imipramine poisoning with cardiac arrhythmias with review of literatures.

Relapsing polychondritis is a rare inflammatory disorder affecting the cartilaginous structures throughout the body. Although there is no pathognomonic laboratory tests, clinical features, when coupled with histopathologic findings, enable one to make a diagnosis of relapsing polychondritis. A 26-year-old man presented with purplish, swollen, and tender auricles and injected eyes. His symptoms had developed eight months ago and fluctuated irrespective of various medications such as corticosteroids and antibiotics. Histopathologic examination revealed loss of basophilic staining of the cartilage with some dissolution of its structures. Treatment was initiated with dapsone, However, the remission was too immediate to be considered as a effect of dapsone.

PURPOSE: This study was designed to investigate that men with prostatodynia have petechiae in the bladder and improvement of symptoms after hydrodistension. MATERIALS AND METHODS: A total of 14 men with the diagnosis of prostatodynia underwent cystoscopy and hydrodistension under a general or regional anesthetic. Their charts were retrospectively reviewed. RESULTS: Of the 14 men 5(36%) had moderate to severe petechiae similar in appearance to women with interstitial cystitis after hydrodistension. Men with moderate to severe bladder petechiae had fewer leukocytes in expressed prostatic secretions and smaller bladder capacities than men with more normal appearing bladders after hydrodistension. Symptomatic improvement 2 to 6 weeks after hydrodistension was more common in men with moderate to severe petechiae than in those with fewer petechiae. CONCLUSIONS: We suggest that bladder petechiae after hydrodistension may be a diagnostic finding in men with prostatodynia as well as women with interstitial cystitis. Therefore, the diagnosis of interstitial cystitis should be considered in patients with prostatodynia.
