OBJECTIVE: There are few published studies which have documented psychopathological abnormalities in patients with of adolescent idiopathic scoliosis (AIS) The aim of this study was to evaluate the psychopathological influence of AIS in Korean 19-year-old males. METHODS: The authors compared the Korean military multiphasic personal inventory (KMPI) military profiles of 105 AIS cases (more than 10 degrees of Cobb's angle without surgical treatment) with the KMPI profiles of 108 normal controls. The AIS group was split depending on Cobb's angle to further evaluate this relation by the severity of AIS. RESULTS: A significantly decreased result on the faking-good response scale and an significantly increased result on the faking-bad response were observed in the AIS group compared to the control (p<0.012). The neurosis scale results, including anxiety, depression and somatization symptoms, were significantly increased in the AIS group compared to the control (p<0.010). The severity level of personality disorder and schizophrenia were also significantly increased in the AIS group (p<0.010). Differences in KMPI scale scores were not related to the severity of AIS. CONCLUSION: Young males with AIS tend to have abnormal results on the multiphasic personal inventory test compared to normal volunteers, suggesting that AIS may be related to psychopathology in the young male group in Korea. Although these psychopathology in AIS were differently observed compared to normal controls, but not interfered with military life. Clinicians are recommended to pay attention the psychopathological traits of patients with AIS.

PURPOSE: To test the hypothesis that chronic subdural hematoma (CSDH) enlarges by the causative factors, this study has performed. METERIALS AND METHODS: In 10 patients with CSDH, coagulation factors in venous blood taken at the time of surgery and hematomic contents aspirated from the CSDH were studied, using both laboratory assays and microscopy. RESULTS: When compared to the range of normal plasma, the hematoma fluids demonstrated a marked reduction in factor II, V, VII, VIII, and X, moderate reduction of factors IX and XI, and slight reduction of factor XII. Activated protein C and antithrombin III levels were decreased. The FDP (Fibrinogen Degradation Product) levels in chronic subdural hematoma were extremely high. The endothelial cells of the macrocapillaries (also called "sinusoid") showed numerous gap junctions between adjacent endothelial cells and a thinness or absence of the basement membrane, suggesting that the macrocapillaries are very fragile and susceptible to bleeding. CONCLUSION: Excessive coagulation in the hematoma, predominantly via the extrinsic clotting pathway, local hyperfibrinolysis, transmitted pulsations, and characteristics of the macrocapillaries play an important role in the leakage of blood and the enlargement of CSDH.

Optic neuritis is a rare extraintestinal manifestation of inflammatory bowel disease. Antitumor necrosis factor alpha (anti-TNF-α) agents are essential treatment options in inflammatory bowel diseases. However, anti-TNF-α agents can implicate optic neuritis and other demyelinating diseases as complications of these agents. We report a patient of infliximab-induced optic neuritis in a patient with ulcerative colitis who was treated with high-dose steroids after discontinuation of infliximab.

BACKGROUND: Infections are still a frequent cause of morbidity and mortality in patients with hematologic malignancies. Antimicrobial prophylaxis in neutropenic patients has been practised for several decades. But, recently the rates of occurrence for pathogens have significantly changed (from predominance of gram-negative to gram-positive species) under selective pressure of antimicrobial prophylaxis, and novel resistance mechanisms have emerged. We investigated this study to assess the effectiveness of selective bowel decontamination for preventing infections in granulocytopenic patients who are receiving chemotherapy for acute myelogenous leukemia. METHODS: In a prospective, randomized trial, we evaluated the efficacy of oral ciprofloxacin (250 mg p.o. twice a day), roxithromycin (150 mg p.o. twice a day), fluconazole (50 mg p.o.) in 95 adult patients with acute myelogenous leukemia who undergone intensive chemotherapy. Prophylaxis was begun within 72 hours of initiation of the chemotherapy and continued until the onset of fever, signs or symptoms of infection, serious adverse effect, or recovery of the leukocyte count to > or = 1,000/mm3. RESULTS: 46 decontamination regimen treated patients and 49 control patients were assessable for efficacy. No difference was noted between the two groups in occurrence of fever during neutropenia, time to onset of first fever, sites of infection, duration of using systemic antimicrobials, overall infection rates, infection-related mortality, or hospitalization day. Decontamination regimen reduced the gram-negative infections, but increased the gram-positive infections. Among those who received decontamination regimen, the incidence of resistance to ciprofloxacin was 100% for gram-negative species. And resistance to erythromycin for gram-positive species, irrespective of decontamination, was very much high (90-100%). CONCLUSION: The approach of selective decontamination has not led to fewer febrile episodes or to a lower mortality in neutropenia after chemotherapy for acute myelogenous leukemia. It should be considered that we had better not prescribe decontamination regimen because of increment of infection due to gram-positive species and high resistance rate to fluoroquinolone and macrolide. Additional trials are needed to establish the efficacy of decontamination for other malignancies, aplastic anemia, or bone marrow transplantation.

Superficial siderosis (SS) in central nervous system is a rare, slowly progressive disease and usually misdiagnosed or diagnosed too late when the patient is chronically devastated. A 55-year-old man with deafness and gait disturbance for ten years was referred from otorhinologist for evaluation of brain. Magnetic resonance image (MRI) showed symmetric hypointense rim partially delineated the bilateral hemisphere on gradient-recalled-echo T2-weighted image, and it was diagnosed as hemosiderin deposition in subarachnoid and subpial meningeal layer. The correct diagnosis of cerebral superficial siderosis can be achieved by careful neurological examination and MRI because computed tomography findings and symptoms are ambiguous. Serial follow-up of imaging study and education for patient are necessary to prevent progression of SS.

PURPOSE: To assess the therapeutic value of two different drainage catheters in treating chronic subdural hematoma (CSDH). MATERIALS AND METHODS: Two types of drainage catheters can be used to treat CSDH according to the position of holes in the catheter: open-type or closed-type catheter. In this retrospective study, 199 total patients with CSDH were reviewed according to catheter type. Among them, 84 patients were and 113 in the closed-type group (holes positioned within the distal-most 1 cm of the catheter). The surgeon selected the catheter type. Total drainage volume, initial drainage volume within 2 days, percentage of initial drainage volume per total drainage volume, duration of catheter insertion, and reoperation rate were compared. RESULTS: Total drainage volume was not different between the two groups (p=0.333). The initial drainage volume within 2 days was larger in the open-type group than closed-type group (p=0.024), but the percentage of initial drainage volume per total drainage volume was not different (p=0.354). The duration of catheter insertion was shorter in the open-type group than closed-type group (p=0.015). The reoperation rate of CSDH was also higher in the open-type group than closed-type group (p=0.004). CONCLUSION: CSDH drainage with an open-type catheter is faster compared with a closed-type catheter, but total drainage volume is similar and reoperation rate is higher. Therefore, the open-type catheter for CSDH drainage has limited clinical value.

BACKGROUND: Small colony variants (SCVs) of Staphylococcus aureus have emerged to be commonly associated with persistent and relapsing infections. Arbekacin (ABK) is one of a few alternatives to vancomycin in intractable case of methicillin resistant S. aureus (MRSA) infection. However, it has not yet been defined whethter ABK tends to be efficacious to the MRSA SCVs. In this study, we employed an in vitro pharmacodynamic infection model (IVPDIM) to define efficacies of ABK against MRSA SCVs. MATERIALS AND METHODS: Using four strains of clinically isolated MRSA (MRSA122, MRSA160, MRSA18, MRSA123), we adopted IVPDIM comprised of two-compartment in which effective surface-to-volume ratio of 5.34 cm(-1). Human pharmacokinetic regimen simulations of ABK were as follows: 100 mg every 12 h (q12h), 200 mg q24h, 200 mg q12h, and 400 mg q24h. Samples were taken from each model at 0, 1, 2, 4, 6, 12, 24, and 30 h, and the bacterial colony counts were determined. The experiments were repeated twice with ABK-administered groups and control group. RESULTS: MICs of ABK for MRSA122, MRSA160, MRSA18, and MRSA123 were 2, 2, 2, and 1 microgram/mL, respectively. In case of MRSA122, MRSA160, MRSA18, C(max)/MIC were less than 9.0 except for ABK 400 mg q24h regimen. In MRSA123, C(max)/MIC were 8.9 on average at ABK 100 mg q12h regimen. But, other regimen showed C(max)/MIC >9. Four regimens for 4 strains showed statistically different colony counts at 30 h (P=0.000). The more dosage or less frequent dosing interval, the more colonies tended to reduce in all strains. In 100 mg q12h groups, SCVs were observed in all strains within 24 h. With increment of dosage or changing dosing interval from q12h to 24h, SCVs were reduced (P=0.000). Regimen of 400 mg q24h did not let SCVs appear in all strains of MIC 2 microgram/mL during the experiments. CONCLUSION: SCVs were observed when MIC of ABK against MRSA were 1-2 microgram/mL, especially in most cases of C(max)/MIC <9. Those findings were also associated with re-growth of colony during the experiments. Once-daily dosing of ABK could reduce or eliminate the appearance of SCV.

PURPOSE: Hypervascular hyperplastic nodules in those patients with chronic alcoholic liver disease and who are hepatitis B and C negative have recently been reported on. The purpose of this study was to correlate the radiologic and pathologic findings with the clinical significance of these hypervascular hyperplastic nodules in chronic alcoholic liver disease. MATERIALS AND METHODS: The study included eight hypervascular nodules of seven patients with chronic alcoholic liver disease, and these patients had abused alcohol for more than 20 years. Eight hypervascular nodules were seen on the arterial phase of dynamic CT scans, but the possibility of HCC was excluded pathologically (n=4) or clinically. The radiologic and pathologic findings, and the changes of these nodules on follow up CT scans were retrospectively analyzed. RESULTS: All nodules showed good enhancement on the arterial phase. The tissue equilibrium phase of the dynamic CT scans showed isodensity in seven patients and low density in one patient. Ultrasound scans revealed hypoechoic findings for three nodules, isoechoic findings for two nodules, hyperechoic findings for one nodule, and two nodules were not detected. Angiograms (n=6) showed late incremental tumor staining, and all the nodules were well seen on the sinusoidal phase. CT during hepatic angiography (n=4) showed well stained tumor. CT during arterial portography (n=4) showed no defect in three nodules and nodular defect in one nodule. The MR images (n=3) showed low signal intensity in two nodules and iso-signal intensity in one nodule on T2WI. Five of six cases for which follow up CT scans were performed showed decrease in size and one was disappeared. CONCLUSION: Radiologically, it is often difficult to differentiate the hypervascular hyperplastic nodules seen in the chronic alcoholic liver disease from hepatocellular carcinoma, and histological confirmation is needed for excluded hepatocellular carcinoma. However, late tumor staining during the sinusoidal phase without any blood supply by feeding vessels or any arterioportal shunt on the angiogram, isodensity during the tissue equilibrium phase of dynamic CT and low signal intensity on T2WI may suggest the presence of hypervascular hyperplastic nodule.
