Mixed gonadal dysgenesis (MGD) with 45X/XY karyotype and patent ductus arteriosus (PDA) is a rare congenital abnormality. A thirty eight month-old male patient was admitted to our urology department for evaluation of ambiguous genitalia. On physical examination, a ptosis, a wide neck with a low posterior hairline, small phallus, testis in the right labioscrotal fold, urethral opening on the penoscrotal junction, and typical findings of patent ductus arteriosus were present. The chromosome karyotype of the patient was 45X/XY. On the laparotomy there were infantile fallopian tubes, ovary and a immature testis on the left. The treatment of the patien1 included gender identity. excision of mullerian structure, left gonadectomy, urethroplasty, biopsy of right testis and double ligation of PDA. We report a case of mixed gonadal dysgenesis with 45X/XY karyotype and patent ductus arteriosus.

OBJECTIVES: MDM-2 is an oncoprotein that inhibits p53 tumor suppressor protein. Amplication and over- expression of its protein have been observed in human malignancies, and these abnormalities have a role in tumorigenesis through inactivation of p53 function. To elucidate the role of p53 and MDM-2 protein in cervical neoplasia we investigated the expression rates of MDM-2 and p53 protein in surgically resected specimens. METHEDS: Immunohistochemical studies using anti-p53 and anti-MDM-2 protein in the paraffin embedded section of 62 cases including cervical intraepithelial neoplasm(CIN) and invasive cervical cancer were performed. RESULTS: Expression rates of p53 protein were 25% in CIN I& CINII, 20% in CINIII, and 44% in invasive carcinoma, respectively. The MDM-2 protein were 33% in CIN I & CIN II, 16% in CIN III, and 48% in invasive carcinoma, respectively. There was no evident correlation between p53 positivity and MDM-2 positivity(p>0.05). However, correlation between MDM-2 negativity and p53 negativity was statistically significant(p=0.002) CONCLUSION: These data suggest that the expression of p53 protein is presumed to be necessarily correlated with MDM-2 protein expression in cervical neoplasia.

Purpose: To report a case of orbital apex syndrome and central retinal vein occlusion after blow-out fracture repair.Case summary: A 22-year-old man who underwent emergency re-operation in a department of plastic surgery due to pain, decreased visual acuity, and ophthalmoplegia in all direction after orbital blow-out fracture repair was referred to ophthalmologist on postoperative day 2 and there was no improvement in symptoms. He showed severe complications, including optic neuropathy and ophthalmoplegia in all direction, central retinal vein occlusion, and outer retinal disruption caused by orbital apex hemorrhage. Although we were concerned that it was too late, we started high dose steroid intravenous pulse treatment and the visual acuity, ophthalmoplegia, and retinal findings were improved. However, the optic atrophy and visual field defect did not. Conclusions After a complicated blow-out fracture repair in other department, if a patient shows severely decreased visual acuity or ocular movement limitation, a thorough and immediate ophthalmologic examination is recommended. During ophthalmologic examination, meticulous examination of the entire eye, including the retina, is required, in addition to general orbital complications. A relatively good prognosis can be expected through accurate cause analysis and appropriate treatment for the confirmed abnormal findings.

This study evaluated the pharmacokinetic profile and therapeutic efficacy of piroxicam (PX), a long acting non-steroidal anti-inflammatory drug for the treatment of arthritis, following intra-articular (IA) injection in comparison to the pharmacokinetic profile and therapeutic efficacy of PX after intramuscular (IM) injection. In the pharmacokinetic study in rats, systemic exposure and pharmacokinetic parameters of PX after a single IA dose were compared with systemic exposure and pharmacokinetic parameters of PX after administration of the same dose IM (0.6 mg/kg). The anti-inflammatory and analgesic effects of IA PX were evaluated simultaneously in a monoiodoacetate-induced osteoarthritis rat model. The plasma PX concentration rapidly rose following IA injection, and it was comparable to the plasma PX concentration following IM injection, suggesting the rapid efflux of the drug molecule from the joint cavity. However, in the efficacy study, the IA PX administration significantly reduced the knee swelling by reducing the level of prostaglandin E2 in the joint, compared to that following administration of IA vehicle and after administration of the IM PX dose. In addition, we found that the anti-inflammatory and anti-nociceptive efficacies of IA PX were synergistically increased upon co-treatment with hyaluronic acid (HA), a potent agent for the treatment of osteoarthritis, at the weight ratio of 1:1 or 1:2, and these effects were more pronounced than those following administration of HA or PX alone. In conclusion, this study demonstrated the efficacy of the IA use of PX alone and/or in combination with HA in osteoarthritis.

A 33-year-old Korean man visited a medical clinic with complaints of throat discomfort and pain for one week. The symptoms occurred one day after eating raw brackish water fish, perch. Endoscopy revealed a fluke, about 5 mm in length, attaching to and peristaltically moving on the surface of the mucosa at the arytenoid region of the larynx. Microscopically, the testes were triangular, tandem, and separated by the uterus. The ovary and cirrus pouch were placed apart from median line between testes. Numerous blood cells were observed in the ceca. The worm was identified to be Clinostomum complanatum. This is the second human case of clinostomiasis in Korea.

Transnasal endoscopic dacryocystorhinostomy (eDCR) has been performed with relative ubiquity since the introduction of the rigid nasal endoscope, with multiple reports found in the literature. Multiple techniques have been used for lacrimal osteotomy, including standard rongeurs, laser, radiofrequency and microdrill. The ultrasonic bone aspirator (UBA) has been described for a variety of neurosurgical procedures and was initially studied in orbital and lacrimal surgery by Sivak-Callcott et al. We report a 74-year-old female patient who suffered from epiphora and pus-like discharge of the right eye. The bone of the lacrimal sac fossa was thinned and removed using an ultrasonic bone aspirator. The patient had a significant symptom improvement without any complications related to UBA use. We applied an ultrasonic bone aspirator for a patient with lacrimal duct stenosis and report a successful result.

Von Meyenburg complexes (VMC) have many synonyms such as bile duct hamartomas and biliary hamartoma. These rare benign disorders are considered as congenital diseases caused by malformed differentiation of ductal plate. The diagnosis of VMC by common radiologic modality such as ultrasound and computed tomography was nearly impossible until the emergence of cholangiopancreatography by magnetic resonance imaging (MRCP) and the pathologic examination was the only way to confirm the diagnosis of VMC. But MRCP is now considered as most accurate noninvasive method for diagnosis of VMC. We report a histologically proven case of VMC associated with calculous cholecystitis, cerebral aneurysm and renal cortical cyst. To our knowledge, no comparable case has been reported and this would be the only second reported case of VMC, which was diagnosed by MRCP.

BACKGROUND: There are different models of skin substitutes, but no skin substitutes have the characteristics of native skin. It was reported that the incubation of skin substitutes in medium containing ascorbic acid extends cellular viability and promotes formation of an epidermal barrier in vitro. OBJECTIVE: The purpose of this study is to observe the effects of ascorbic acid on the proliferation of keratinocytes and on the reconstruction of epidermis. MATERIALS AND METHODS: Normal human keratinocytes and fibroblasts were isolated and used for culturing living skin equivalent (LSE). RESULTS: When ascorbic acid was added, the expression of p63 and a6 integrin was definitely increased compared to control models. In addition, ascorbic acid increased the proliferation of normal human keratinocytes at a dose dependent manner. Especially, ascorbic acid induced the phosphorylation of ERK and up-regulation of EGF-R CONCLUSION: Results suggest that ascorbic acid is essential in the control of keratinocyte proliferation and basement membrane formation. Ascorbic acid-related keratinocytes proliferation is seemed to be mediated by ERK phosphorylation and EGF-R up-regulation.

Purpose: To predict the presence of tractional retinal detachment (TRD) in eyes with dense vitreous hemorrhage (VH) and proliferative diabetic retinopathy (PDR) by evaluating the status of posterior vitreous detachment (PVD) in fellow eyes using optical coherence tomography (OCT). Methods: A total of 44 eyes from 22 patients who underwent vitrectomy due to dense VH with PDR were enrolled. Using OCT, the PVD status in the fellow eye was divided into two groups (incomplete and complete PVD). The incomplete PVD group included eyes without PVD and eyes with partial PVD. B-scan ultrasonography was performed on eyes with dense VH to evaluate the presence of TRD. Both OCT and B-scan images were reviewed by four ophthalmologists (two novices and two experienced), and the interobserver agreement was evaluated. Results: There was a difference in the interobserver agreement regarding the presence of TRD in eyes with dense VH evaluated by B scan between novice and experienced ophthalmologists (novice, κ = 0.421 vs. experienced, κ = 0.814), although there was no difference between novice and experienced ophthalmologists in the interobserver agreement regarding the status of PVD in the fellow eye evaluated by OCT (novice, κ = 1.000 vs. experienced, κ = 1.000). All observed TRD during vitrectomy occurred in eyes with incomplete PVD in the fellow eye. Logistic regression analysis revealed a statistically significant relation between TRD and the age of the patient (odds ratio [OR], 0.874; p = 0.047), and between TRD and incomplete PVD in the fellow eye evaluated by OCT (OR, 13.904; p = 0.042). Conclusions Evaluation of the PVD status in the fellow eye using OCT may be a useful predictor for detecting the presence of TRD in eyes with dense VH and PDR.
