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.

Medial orbital wall fracture can easily be overlooked because typical clinical symptoms appear in only a few instances. However, if it is left untreated in case of no diplopia, cosmetically undesirable enophthalmos may develop. Various cutaneous approaches, previously used, may leave noticeable scar or provide a limited overview of the orbit medial wall fracture site. We used the transcaruncular approach in 36 cases of 35 patients for reconstruction of the medial orbital wall fracture. The incision was made at the junction of the medial 3/4 and lateral 1/4 of the caruncle, and extended along the conjunctival fornix superiorly and inferiorly to or beyond both puncta for 10 - 15 mm long respectively. After soft tissue was dissected, periosteum was incised at the posterior to the posterior lacrimal crest. Implants up to a height of 2.5 cm could be inserted.The diplopia was resolved in all cases after the surgery, and enophthalmos measured 0 to 2 mm in all patients. Postoperative computed tomographic scans showed favorable reduction of the herniated soft tissues and anatomic reduction of the medial wall without complication related to the surgical approach in all cases. Transcaruncular approach is a better alternative to transcutaneous incisions because it provides wide exposure of the medial orbital wall, no visible cutaneous scar, short operation time, and no damage of important internal structures.

Although urinary tract infections are common in adults, pyelonephritis is rarely considered in the differential diagnosis of acute renal failure. Acute pyelonephritis without urinary tract obstruction, previous renal diseases or septic shock is a rare cause of acute renal failure. Despite appropriate antibiotic therapy, recovery of renal function could be slow and incomplete. We experienced a 45 year-old woman with diabetes who developed bilateral acute pyelonephritis followed by acute renal failure. The renal biopsy revealed diffuse edematous and focal fibrotic inters- titium with infiltration of lymphocytes compatible with interstitial nephritis. Although her renal function improved gradually with antimicrobial treatment, the process was incomplete and renal dysfunction persisted at about 10-month follow-up, suggesting permanent renal damage. Therefore, we report this case with brief review of related literature.

The authors report a case of angiographycally occult intracranial vascular malformation. The patient had huge calcified mass at left frontoparietal area. The preoperative diagnosis was a slowly growing benign tumor. The mass was very hard and so vascular malformation was not suspected even during the operation. Pathologic report revealed arteriovenous malformation.
