PURPOSE: This study was performed to evaluate the effect of bovine pericardium used in scleral ulcer resulting from excision of pterygium and MMC. METHODS: Nine eyes of 9 patients who had painful scleral ulcer resulting from excision of pterygium and MMC were repaired with bovine pericardium (Lyoplant(R)). The rotation conjunctival flap was placed over the graft area. We measured the results and complications of treatment. RESULTS: Eight patients showed loss of eyeball pain, epiphora, and inflammation. There were visual improvement, good conjunctival healing after the procedure. One patient showed loss of overlying conjunctiva and progression of scleral ulcer because of pseudomonas infection. After control of infection and secondary procedure, there were good conjunctival healing, relief of the symptom and visual improvement. CONCLUSIONS: The authors suggest bovine pericardium appears to be an excellent substitute for autogenous or homologous tissue in scleral ulcer treatment.

Alpasia cutis congenita is an anomaly characterized by absence of localized areas of the integument. The most common type of aplasia cutis congenita is Aplasia cutis congenita limited to the scalp, although other areas of the body may also be involved. We experienced a case of aplasia cutis congenita in a male newborn infant. The skin defects were extensive with symmetrical involvement of lower extremities. The multiple bullae were found on the both fingers and toes. No similar conditions and other associated congeital anomalies were found in the family membes of this particular case. The light microscopic examinaton of the denuded skin areas how absence of epidemis and the demis contain atrophic and hypoplastic adnexa. The bullae have a split within the dermis below lamina densa on electron microscopy. The skin defects were healed by supportive therapy for 4weeks.

PURPOSE: The purpose of this study is to describe the patterns of enhancement of the herniated lumbar disc with Gd-DTPA enhanced MR imaging. MATERIALS AND METHODS: Out of 65 patients, 103 lumbar discs diagnosed to be herniated by MR image were retrospectively analyzed. The MR imaging was performed with 1.5 T MR unit, using T1- and T2- weighted sagittal and axial spin echo techniques. Contrast- enhanced T1 weighted sagittal and axial images were performed after intravenous injection of Gadopentetate-dimeglumine(Magnevist, Shering) (0.1 mmol/kg). RESULTS: Contrast enhancement was seen in 66 cases(64%). Thirteen cases of bulging disc were not enhanced. Twenty-eight cases of protruded disc showed intraannular enhancement in 23 cases, peripheral linear and irregular enhancement in each of one case, and nonenhancement in three cases. Fifty-seven cases of extruded disc showed irregular enhancement in 14 cases, peripheral linear enhancement in 12 cases, peripheral ring enhancement in five cases and intraannular enhancement in five cases. All five cases of sequestered disc showed peripheral ring enhancement. CONCLUSION: Protruded discs show intraannular enhancement frequently and sequestered discs usually show peripheral ring enhancement. Enhanced MR imaging may be helpful to evaluate the type of herniated lumbar disc and relationship among disc material, nerve root and thecal sac.

PURPOSE: To assess the usefulness of MRI in preoperative diagnosis of congenital anorectal malformation MATERIALS AND METHODS: MR findings of 11 cases with surgically proved anorectal malformations were retrospectively reviewed and compared with operative findings, according to the level of atresia, the development of sphincter muscle, fistula and associated anomalies of other organs. RESULTS: Four of 11 cases were low type of anorectal atresia, 3 cases were intermediate type, and 3 cases were high type. There was one case of Currarino triad with low type of anorectal stenosis. MRI demonstrated the levels of atresia correctly in all cases and revealed fistulas in all high type of anomalies. Degrees of the development of the sphincter muscles were good in all cases of low types and fair in a case of intermediate type and an anorectal stenosis, whereas the development was poor in 2 cases of intermediate type and all 4 cases of high type. The associated anomalies in anorectal malformation were renal agenesis, congenital hip dysplasia and sacral defect with presacral teratoma in Currarino triad. CONCLUSION: MRI was a simple and useful study to confirm the level of atresia, fistula and associated anomalies in the diagnosis of the congenital anorectal malformation.

OBJECT: Currently, the alteration of cytokine system has been known to play an important role in regard to depressive symptom. We focused on the relationship between immunological parameters and clinical improvement in major depressive disorder. METHOD: Data were collected on 26 patients with major depressive disorder using a 8-week prospective follow-up design. After 8-week treatment period with fluoxetine, patients were classified into a response group and a non-response group according to their psychopathological outcome as evaluated by Hamilton Depression Rating Scale. The differences of the immunological parameters between pre-treatment phase and post-treatment phase were compared among patients. The difference of those was also compared within each phase among them. The relationship between socio-demographic variables, depression, cytokine, mononuclear cells was examined by correlation analysis. Multiple regression analyses were performed to explore the predictors of clinical improvement of major depressive disorder. RESULT: Pre-treatment levels of IL-1beta in the response group were significantly higher than those in the non-response group. Pre-treatment levels of IL-1beta of all patients and in the response group were positively correlated with pre-treatment monocyte counts. Patients with subsequent remission showed significantly lower IL-6 values at baseline than those with non-response. Post-treatment values of IL-6 did not differ significantly among the patients. The correlation test showed more frequent relations among cytokines and mononuclear cells in the response group than in the non-responder group. Especially, serum level of IL-6 in pre-treatment phase was only significantly correlated with HAMD score after 8-week treatement phase, while other cytokines and mononuclear cells were not. Pretreatment level of IL-6 was of paramount importance in predicting clinical improvement of depressive symptom. CONCLUSION: The immune system of major depressive disorder patients might dichotomize the patients into subsequent responders and non-responders. Immune system might be of great influence on the clinical improvement of major depressive disorder. The mode of interaction between depression and cellular immune function and the mediators responsible for the cytokine production need to be studied further.

BACKGROUND: This study is aimed at the pathoanatomic correlates of depression and anxiety in acute stroke patients including subcortical lesion(periventricular hyperintensity, deep white matter hyperintensity, subcortical gray matter hyperintensity). METHODS: Sixty nine patients with acute stoke were recruited. Their brain lesions were measured using Brain MRI. Depressive or anxiety symptoms were rated by Beck depression inventory(BDI) or Beck anxiety inventory, respectively. RESULTS: There were significant correlation between depression and periventricular hyperintensity and deep white matter hyperintensity in acute stroke patients. There are no significant pathoanatomic correla- tions between anxiety and brain lesions on MRI. CONCLUSION: Our findings suggest that the white matter lesion may increase the risk of depression after stroke. Prevention of asymptomatic cerebrovascular lesion could decrease the risk of depression in acute stroke patients as well as the risk of stroke.

OBJECTIVE: Epidural venous varicosity (congestion of the epidural vein) is rarely introduced as an influential factor of clinical symptoms. However, there are several studies suggesting that epidural venous varicosity results in neurologic symptoms. We would like to highlight evidence that epidural venous varicosity results in neurologic symptoms and the relation between epidural venous varicosity and neural structure observed during the surgery. Based on our experiences, we also propose a new classification of epidural venous varicosity. METHODS: 29 patients with symptomatic lumbar stenosis received microsurgical decompression via partial hemilaminectomy. The authors retrospectively reviewed all recorded intraoperative pictures and categorized patterns of venous varicosities with relationship to neural structures. RESULTS: Type A is conditions in which epidural veins are dilated but located parallel to the nerve root on the lateral side of the nerve root and thus do not compress the nerve root. Type B is conditions in which varices are located on the anterior lateral side of the nerve root to compress the nerve root. Type C is conditions in which varices are encircled around the nerve root and compressing the nerve root. CONCLUSION: Epidural venous varicosity is observed in most lumbar stenosis patients with clinical symptoms. Of the types, the types of epidural venous varicosity compressing nerve structures were Type B and Type C. All epidural venous varicosities were removed regardless of classification during operations. Most patients showed relief in clinical symptoms after the operation. We thought to epidural venous varicosity as a factor that causes clinical symptoms of lumbar stenosis.
