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.

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.

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.

BACKGROUND: Hypertension is the most common cause of left ventricular hypertrophy(LVH). Increased left ventricular mass(LVM) carries independent risk for congestive heart failure, coronary artery disease, sudden death, reduction of coronary reserve. The importance of treatment in systemic hypertension for cardiovascular morbidity and mortality has been estabilished. Regression of LVM occurs with a number of antihypertensive drugs. This study was designed to explore the relation between blood pressure control, LVM and left ventricular filling dynamics. METHODS: Twenty five patients (12 men, 13 women) with estabilished hypertension were studied. No patients had a previous history of antihypertensive therapy. We obtained the basal echocardiography at the diagnosis which were disclosed no definite LVH, and the follow-up echocardiography after 6 months antihypertensive therapy with angiotension converting enzyme inhibitor, fosinopril, in patients with untreated essential hypertension. RESULTS: 1) Baseline blood pressure was 150/125mmHg and fell to 104/85mmHg (p<0.001). There was no siginificant reduction in heart rate. LVM were reduced from 153gr/m2 to 129gr/m2. 2) Peak E velocity and Peak A velocity was 82.9cm/sec, 74.9cm/sec and reduced to 67.2cm/sec, 62.3cm/sec, (p<0.001). 3) Time velocity integral dimension E (Ei) and time velocity integral dimension A (Ai) was 13.0cm, 9.0cm and reduced to 8.6cm, 4.5cm respectively. But there was no significant inteval change in peak E/A velocity. Ei/Ai was increased from 1.7 to 2.1 (p<0.01). CONCLUSIONS: These results suggested that antihypertensive therapy with ACE inhibitor for 6 months reduced significantly the left ventricular mass in patients with untreated essential hypertension.

Renal transplant recipients requiring aortic reconstruction due to abdominal aortic aneurysm (AAA) pose a unique clinical problem. The concern during surgery is causing ischemic injury to the renal allograft. A variety of strategies for protection of the renal allograft during AAA intervention have been described including a temporary shunt, cold renal perfusion, extracorporeal bypass, general hypothermia, and endovascular stent-grafting. In addition, some investigators have reported no remarkable complications of the renal allograft without any specific measures. We treated a case of AAA in a patient with a renal allograft using a temporary aortofemoral shunt with good result. Since this technique is safe and effective, it should be considered in similar patients with AAA and previously placed renal allografts.

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.
