The authors analyzed 53 cases with spontaneous intracerebellar hemorrhage diagnosed by brain CT scan and assessed the correlation between the mental status at admission, the outcome and the CT findings. The location of hematoma, volume of hematoma, quadrigeminal cistern obliteration, intraventricular hemorrhage and hydrocephalus were correlated to the mental status assessed by GCS at admission. The GCS score at admission, location of hematoma, volume of hematoma, quadrigeminal cistern obliteration, intraventricular hemorrhage and hydrocephalus were correlated to the outcome. We conclude that decreased GCS score at admission, large volume of hematoma, quadrigeminal cistern obliteration, presence of intraventricular hemorrhage and hydrocephalus could be considered as surgical indications and contributing factors for poor prognosis in the patients with spontaneous intracerebellar hemorrhage.

Congenital dermal sinus (CDS) is a rare entity widely known to occur as a result of the of the failure of the neuroectoderm to separate from the cutaneous ectoderm during the process of neurulation at the third to fifth week of gestation. The lesion can occur at any level of the craniospinal axis, but are located predominantly at the lumbosacral and occipital region. CDS of thoracic region and cervical region are rare. The patient with CDS presents with meningitis and/or mass effect from the associated inclusion tumor. They are usually dermoid or epidermoid cyst. Teratoma is rarely associated with CDS. We report our experience of CDS an 11-month old boy associated with an intramedullary dermoid tumor at the thoracic region, and together we report a review of the literature.

PURPOSE: To report the clinical outcomes of a volar plate reinforcing technique with free tendon grafts after sesamoid excision for the surgical treatment of subsesamoid arthritis of the metacarpophalangeal (MCP) joint of the thumb. MATERIALS AND METHODS: Eleven consecutive patients that underwent sesamoid excision and volar plate reinforcement using a palmaris longus free tendon graft were enrolled. There were 7 males and 4 females, with an average age of 46 (range, 30-56 years). Post-traumatic arthritis after a hyperextension injury of the thumb was present in 9 patients. Two patients had idiopathic arthritis. All patients were evaluated by objective and subjective criteria, the mean follow-up duration was 19 months (range, 12-35 months). RESULTS: The results were satisfactory overall (3 excellent, 7 good, 1 poor). The mean grip strength and pinch strength significantly improved from 63.0% and 51.3%, respectively, preoperatively, to 84.9% and 88.9%, postoperatively. The mean range of motion for the MCP joint was -5.9/50.9 degrees. The mean DASH and MHQ scores showed significant improvement compared to the preoperative scores. CONCLUSION: The early clinical results suggest that the described technique is a safe and effective option for subsesamoid arthritis of the MCP joint of the thumb.

Objectives: This study aimed to test the effect of photodynamic therapy (PDT) on the inhibition and removal of biofilms containing multidrug-resistant Acinetobacter baumannii. Methods: Using multidrug-resistant A. baumannii strains, an antibiotic susceptibility test was performed using the Gram-negative identification card of the Vitek 2 system (bioMérieux Inc., France), as well as an analysis of resistance genes, the effects of treatment with a light-emitting diode (LED) array using Radachlorin (RADA-PHARMA Co., Ltd., Russia), and transmission and scanning electron microscopy to confirm the biofilm-inhibitory effect of PDT. Results: The antibiotic susceptibility test revealed multiple resistance to the antibiotics imipenem and meropenem in the carbapenem class. A class-D–type β-lactamase was found, and OXA-23 and OXA-51 were found in 100% of 15 A. baumannii strains. After PDT using Radachlorin, morphological observations revealed an abnormal structure due to the loss of the cell membrane and extensive morphological changes, including low intracellular visibility and small vacuoles attached to the cell membrane. Conclusion PDT involving a combination of LED and Radachlorin significantly eliminated the biofilm of multidrug-resistant A. baumannii. Observations made using electron microscopy showed that PDT combining LED and Radachlorin was effective. Additional studies on the effective elimination of biofilms containing multidrug-resistant bacteria are necessary, and we hope that a treatment method superior to sterilization with antibiotics will be developed in the future.

PURPOSE: Contrast enhanced multidetector computed tomography (MDCT) has been used as an alternative to coronary angiography for the assessment of coronary artery disease in the patient of the intermediate risk group. However, coronary calcium is a known limiting factor for MDCT evaluation. We investigated the diagnostic accuracy of 64-channel MDCT with each coronary artery calcium score (CACS) by compared with intravascular ultrasound (IVUS) imaging. MATERIALS AND METHODS: A total of 54 symptomatic patients with intermediate-risk (10 females, mean age 59.9+/-6.9 years, Framingham point scores 9-20) with 162 sites who had a culprit lesion on 64-channel MDCT before performing coronary angiography with IVUS were enrolled. Patients were divided into 4 subgroups depending on CACS: 0, 1-99, 100-399, and >400. Lesion length, external elastic membrane (EEM) cross sectional area (CSA), minimal luminal area, and plaque area were measured and compared between IVUS and MDCT. RESULTS: The correlation coefficients for the measurements of the EEM CSA, lumen CSA, and plaque area were r=0.514, r=0.837, and r=0.578, respectively. Furthermore, there were close correlation of plaque area between four subgroups of CACS (r=0.671, r=0.623, r=0.562, r=0.571, respectively). CONCLUSION: Despite the increase in CACS, the geometric analysis of coronary arteries using with 64-channel MDCT was comparable with IVUS in symptomatic patient of the intermediate risk group.

PURPOSE: To evaluate the usefulness of color Doppler ultrasonography in the differential diagnosis of breast masses. MATERIALS AND METHODS: We prospectively evaluated to pathologically proven breast lesions. Forty-three were benign (39 fibroadenomas, two papillomas and two lipoma) and 27 were malignant (25 infiltrating ductal cardinomas, one mucinous carinoma and one atypical medullary caricinoma). In 32 cases, we categorized color signal from 0 to III, according to the degree of vascularity, and analysed peak systolic velocity (PSV) and resistive index (RI). RESULTS: Color signals of malignant lesions tended to be high grade (II, III), whereas those of benign lesions tended to be low (0, I), and the difference was statistically significant (P<0.005). In the analysis of spectral waveform , correlation between RI, PSV and malignancy was statistically significant (P<0.02). RI above 0.7 and PSV above 10 were the highest recorded values for sensitivity and specificity. CONCLUSION: Color Doppler ultrasound is a useful modality to distinguish benign from malignant breast masses. Malignancy is suggested when the color signal is grade II or III, the resistive index is higher than 0.7, and peak systolic velocity is higher than 10cm/sec.

PURPOSE: To assess the usefulness of Gd-DTPA MRI in the evaluation of the characteristics of intracranial meningiomas and in the correlation with their histopathologic pattern. MATERIALS AND METHODS: We retrospectively analyzed the Gd-DTPA MRI findings in 22 cases of histologicalty-proven intracranial meningiomas. The images were assessed for signal intensity, internal texture, peritumoral edema, and enhancement characteristics. Computed tomograms were obtained in 18 cases and compared with MRI findings. RESULTS: Tl-weighted images were not particularly useful for discriminating pathologic subtype, but signal intensity on T2-weighted images were relatively well correlated with histopathologic findings. A heterogeneous texture produced by tumor vascularity, calcification, cystic foci, hemorrhagic necrosis, or psammoma body was relatively well shown on Gd-DTPA Tl-weighted image compared with that on T1- or T2-weighted image. Gd-DTPA Tl-weighted images revealed a dural tail sign in 19 cases(83%). Angioblastic type was slightly hypointense on Tl-weighted image and markedly hyperintense on T2-weighted image. Psammomatous type and firboblastic type were isointense on both T1- and T2-weighted image. Fibroblastic type was more densely enhanced than the other. The transitional, atypical, and papillary types showed tendency of heterogeneous enhancement. CONCLUSION: Gd-DTPA MRI was a useful imaging modality in evaluation of the characteristics of meningiomas and correlated well with the pathologic patterns.

BACKGROUND: According to the increasing rate of cesarean section, the efforts of seeking safer and more satisfactory obstetric anesthesia techniques have been continued. Propofol, 2,6 di-isopropyl phenol, is a relatively new intravenous anesthetic agent and has been used for induction and maintenance for total intravenous anesthesia (TIVA). Authors examined the anesthetic technique using following anesthetics combinations; N2O-propofol, fentanyl-propofol, ketamine-propofol and made comparison of these ones for intraoperative hemodynamic stability, maternal and fetal safety. METHODS: Sixty patients (ASA physical status 1 or 2) scheduled for cesarean section were randomly allocated into three groups, group N (propofol-N2O, n=20), group F (propofol-fentanyl, n=20), group K (propofol-ketamine, n=20). We checked the changes of blood pressure and heart rates during operation, anesthetic induction time, neonatal status (Apgar score, umbilical vein blood gas analysis), presence of intraoperative awareness and recovery time. RESULTS: No significant differences in intraoperative hemodynamic changes, induction time and baby status. Total propofol dosages were greater in group N than group K (p<0.05) and maternal recovery time was prolonged in group K than group N or F (p<0.05). CONCLUSIONS: Anesthetic management using propofol-N2O or propofol-fentanyl or propofol-ketamine for cesarean section would provide satisfactory anesthesia without significant adverse effects to both mother and fetus.
