PURPOSE: Radius-Maumenee syndrome (RMS) is characterized by idiopathic dilated episcleral vessels usually associated with glaucoma. The authors report a case of a 32-year-old Korean male with dilation of the episcleral vessels and glaucoma in both eyes. CASE SUMMARY: A 32-year-old Korean male presented with conjunctival injection and chronic pulsatile ocular pain in both eyes for 11 years. His best corrected visual acuity was 20/20 in both eyes. Slit lamp biomicroscopy showed episcleral venous engorgement in both eyes. Fundus photographs revealed superotemporal and inferotemporal retinal nerve fiber layer defects and Humphrey visual field testing showed superior nasal steps and paracentral scotomas in both eyes. He suffered from chronic eye pain in both eyes although he had applied glaucoma medication and his symptoms had worsened during the past year. Brain magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) revealed no evidence of carotid cavernous fistula or other orbital lesions. Due to the presence of episcleral venous engorgement, glaucoma and negative tests for other possible diseases, he was diagnosed with RMS. CONCLUSIONS: RMS is an idiopathic disease with episcleral vessel dilation and frequently associated with glaucoma. Its diagnosis is confirmed by eliminating other possible causes of episcleral venous engorgement.

Rhabdomyomas are rare benign tumors. Most extracardiac rhabdomyomas are found in the head and neck region, especially in the pharynx and larynx. Herein, we have described the case of a 1-year-old boy presenting with recurrent otorrhea and postauricular swelling. His symptoms were due to a mass that was histologically diagnosed as fetal rhabdomyoma (FR). Here, we report the first case of FR in the postauricular area. Clinicians should keep in mind the possibility of FR if a child presents with external auditory canal mass associated with recurrent otorrhea and signs of mastoiditis.

The purpose of this study was to assess the current materials, methods and difficulties according to the year of licence and educational background of Korean dentists in Class II direct composite resin restorations. Total 17 questions were included in the questionnaire. Questions were broadly divided into two parts; first, operator's information, and second, the materials and methods used in Class II posterior composite restoration. The questionnaire was sent to dentists enrolled in Korean Dental Association via e-mail. Total 12,193 e-mails were distributed to dentists, 2,612 e-mails were opened, and 840 mails (32.2%) were received from respondents. The data was statically analyzed by chi-square test using SPSS(v. 12.0.1, SPSS Inc, Chicago, IL, USA). Male dentists among respondents was 79%. 60.3% of the respondents acquired their licences recently (1998-2007), and 77% practiced in private offices. 83.4% have acquired their knowledge through school lectures, conferences and seminars. For the Class II restorations, gold inlays were preferred by 65.7% of respondents, while direct composite resin restorations were used by 12.1% amalgam users were only 4.4% of respondents. For the restorative technique, 74.4% of respondents didn't use rubber dam as needed. For the matrix, mylar strip (53.4%), metal matrix (33.8%) and Palodent system (6.5%) were used. 99.6% of respondents restored the Class II cavity by incremental layering. Obtaining of the tight interproximal contact was considered as the most difficult procedure (57.2%) followed by field isolation (21%). Among various bonding systems, 22.6% of respondents preferred SE Bond and 20.2% used Single Bond. Z-250 was used most frequently among a variety of composite resins.

Status epilepticus is rare complication of cerebral hyperperfusion syndrome and is a critical medical emergency that requires potent anesthetics. Propofol has the advantages of being rapid-acting and possessing a weaker cardiopulmonary suppression profile, but its use is associated with serious propofol infusion syndrome. We report herein a case of cerebral hyperperfusion syndrome after carotid endarterectomy presenting with refractory partial status epilepticus and fatal outcome associated with propofol infusion syndrome.

The selective cyclooxygenase-2 (COX-2) and 5-lipoxygenase (LOX) inhibitors might inhibit prostaglandin synthesis and reduce proteinuria. The present study was designed to investigate the anti-proteinuric effects of nordihydroguaiaretic acid (NDGA) as compared with celecoxib in puromycin aminonucleoside (PAN) nephrosis rats. Fifty five male Sprague-Dawley rats were divided into 4 groups; A, normal control; B, PAN group; C, PAN+COX-2 inhibitor (celecoxib) group; and D, PAN+5-LOX inhibitor (NDGA) group. After induction of PAN nephrosis through repeated injections of PAN (7.5 and 15 mg/100 g body weight), rats were treated with celecoxib, NDGA, or vehicle for 2 weeks. Twenty four hour urine protein excretions were significantly lower in PAN+celecoxib and PAN+NDGA groups than in PAN group. Serum creatinine (SCr) concentrations and 24 hr urine creatinine clearances (CCr) were not significantly different in the four groups. Electron microscopy showed that podocyte morphology was changed after the induction of PAN nephrosis and was recovered after celecoxib or NDGA administration. Celecoxib significantly recovered the expressions of nephrin, CD2AP, COX-2, and TGF-beta. NDGA also recovered TGF-betaexpression, but did not alter the expressions of nephrin, CD2AP and COX-2. The present study suggested that celecoxib and NDGA might effectively reduce proteinuria in nephrotic syndrome without impairing renal function.

5-Lipoxygenase inhibitor and human recombinant erythropoietin might accelerate renal recovery in cisplatin-induced acute renal failure rats. Male Sprague-Dawley rats were randomized into four groups: 1) normal controls; 2) Cisplatin group-cisplatin induced acute renal failure (ARF) plus vehicle treatment; 3) Cisplatin+nordihydroguaiaretic acid (NDGA) group-cisplatin induced ARF plus 5-lipoxygenase inhibitor treatment; 4) Cisplatin+erythropoietin (EPO) group-cisplatin induced ARF plus erythropoietin treatment. On day 10 (after 7 daily injections of NDGA or EPO), urea nitrogen and serum Cr concentrations were significantly lower in the Cisplatin+NDGA and Cisplatin+EPO groups than in the Cisplatin group, and 24 hr urine Cr clearances were significantly higher in the Cisplatin+EPO group than in the Cisplatin group. Semiquantitative assessments of histological lesions did not produce any significant differences between the three treatment groups. Numbers of PCNA(+) cells were significantly higher in Cisplatin, Cisplatin+NDGA, and Cisplatin+EPO groups than in normal controls. Those PCNA(+) cells were significantly increased in Cisplatin+NDGA group. These results suggest that EPO and also NDGA accelerate renal function recovery by stimulating tubular epithelial cell regeneration.

Adenoid cystic carcinoma (ACC) is a rare type of breast carcinoma and this tumor makes up less than 0.1% of all mammary carcinomas; ACC is known to show a relatively favorable prognosis. Among a variety of microscopic growth patterns of mammary ACC, a solid variant is the rarest and this can cause diagnostic difficulties. We present here a case of a solid variant of mammary ACC that occurred in the right breast of a 40-year-old woman who was initially diagnosed with invasive ductal carcinoma. We discuss the histological and clinical characteristics of this case.

BACKGROUND: Despite using renin-angiotensin system (RAS) blockades, some of the patients with immunoglobulin A (IgA) nephropathy often had persistent proteinuria of more than 500mg/d. They need to be managed further by alternative methods to halt the progression of the disease; these methods could also be applied safely over a long period of time. In this context, sulodexide has been studied for the management of diabetic nephropathy. METHODS: A retrospective review was carried out involving 20 patients with IgA nephropathy who had been taking sulodexide (50mg daily) as an add-on therapy together with an optimal dose of RAS blockades during 2008-2009. We evaluated the proteinuria reduction rates and renal function changes. RESULTS: During 11.1+/-72.7 months of follow-up duration, urinary protein-to-creatinine ratio (UPCR) decreased for 1.57+/-0.6 to 1.17+/-0.7 g/g (P=0.032). Twenty-five percent of the patients showed a greater than 50% reduction of UPCR, and 40% had a UPCR of less than 1.0g/g at their final observations. The analysis of the factors contributing to the effect found that a higher pretreatment UPCR showed a significant correlation with the UPCR decrease (r=0.45, P=0.047). Neither the adverse effects nor the renal function impairments were documented during the management. CONCLUSION: Low-dose sulodexide has an additional modest antiproteinuric effect on IgA nephropathy undergoing RAS blockade therapy.

A 74-yr-old woman presented with fever and abdominal discomfort. She was in a septic condition caused by urinary tract infection. Her computed tomogram of the abdomen revealed features of hydronephrosis with ureteral stones in both kidneys. During percutaneous nephrostomies, right pyeloduodenal fistula (PDF) was diagnosed. Elective surgery was originally planned but the patient was in a poor condition to undergo surgery. Instead, 2 times endoscopic clipping and ligation by endoloop were applied with parenteral antibiotics for the fistula lesion. On admission day 30, she was discharged from the hospital after confirmation of no more contrast leakage on fistulography. We reviewed the literature and discuss the etiologies, clinical presentations, diagnosis, and treatment of PDF.
