Testicular involvement in male patients with leprosy is well documented and may be associated with impotence, sterility and gynecomastia. Testicular histology shows atrophy of the seminiferous tubules with hypertropy and clumping of Leydig cells and hyalinization of the small and medium sized vessels. The hormonal functions of the testes have been studied by a number of workers, usually in patients with testicular atrophy and gynecomastia. In these particular patients, androgens are generally diminished while gonadotropins are increased. The pathogenesis of testicular damage is uncertain, though Wall and Wright(1974) found that testicular germinal cell antibodies were present in 75% of lepromatous, and postulated that :autoirnmunity, Erythema Nodosum Leprosum imrnune complex damage and direct invasion by Mycobacterium leprae may all be contributory.

Although obstruction of the carotid artery after head trauma or non-penetrating injuries of the neck had been well known, reports of occlusion of middle cerebral artery following closed head trauma are rare. Up to now Jacque, et al, have found only 22 cases of posttraumatic middle cerebral artery occlusion including their own one case in the world literatures since DeVeer and Browder reported the first case in 1942. We report a case of posttraumatic middle cerebral artery occlusion. The patient developed right hemiplegia, aphasia and mental confusion 2 days following closed head trauma. Left cerotid angiograms revealed complete occlusion of the horizontal portion of the left middle cerebral artery distal to the origin of the lenticulostriate branches. Previously reported cases are review and possible pathophysiological mechanisms discussed.

BACKGROUND: Linear lichen planus (LLP) and Lichen striatus (LS) are rare disorder that can be confused because they can share similar clinical and histopathologic features. OBJECTIVE: The purpose of this study was to evaluate the characteristic differences and common features between the two disorders histopathologically. METHODS: We reviewed the clinical records of patients who had been diagnosed as LLP or LS in our dermatology clinic during the 15-year period between 1985 and 1999. We classified twenty seven cases, which were differentiated from other possible linear dermatoses, into LLP and LS on the basis of clinical features, and then compared them histopathologically, and appreciated the characteristic differences or common features of the two disorders. RESULTS: In cases diagnosed as LLP clinically, epidermal changes were mainly composed of hyperkeratosis (78%), acanthosis (78%), basal degeneration (78%), granular layer thickening (67%) and saw-toothed appearance of rete ridges (44%). In dermis, colloid bodies (78%), band-like inflammatory cell infiltration with pigmentary incontinence (78%) were strik-,ting findings. In cases with clinical features of LS, parakeratosis (50%), dyskeratotic cells scattered in the epidermis (61%) and intercellular edema (39%) were noted in the epidermis. Dermal cellular deposits were focally band-like infiltration(89%), more frequently perivascular in-filtration (83%) and often involved deep dermis (50%), hair follicles (44%) and eccrine glands (22%) in contrast to LLP. CONCLUSION: This study presents a comparative histopathologic features of LLP and LS. Three cases of LLP with overlapping histopathologic features suggest the possibility that there may be an intermediate form between either end of a spectrum, LLP and LS.

BACKGROUND/OBJECTIVES: Anti-inflammatory and antioxidative activities of luteolin and luteolin-7-O-glucoside were compared in galactosamine (GalN)/lipopolysaccharide (LPS)-induced hepatitic ICR mice. MATERIALS/METHODS: Male ICR mice (6 weeks old) were divided into 4 groups: normal control, GalN/LPS, luteolin, and luteolin-7-O-glucoside groups. The latter two groups were administered luteolin or luteolin-7-O-glucoside (50 mg/kg BW) daily by gavage for 3 weeks after which hepatitis was induced by intraperitoneal injection of GalN and LPS (1 g/kg BW and 10 µg/kg BW, respectively). RESULTS: GalN/LPS produced acute hepatic injury by a sharp increase in serum AST, ALT, and TNF-α levels, increases that were ameliorated in the experimental groups. In addition, markedly increased expressions of cyclooxygenase (COX)-2 and its transcription factors, nuclear factor (NF)-κB and activator protein (AP)-1, were also significantly attenuated in the experimental groups. Compared to luteolin-7-O-glucoside, luteolin more potently ameliorated the levels of inflammatory mediators. Phase II enzymes levels and NF-E2 p45-related factor (Nrf)-2 activation that were decreased by GalN/LPS were increased by luteolin and luteolin-7-O-glucoside administration. In addition, compared to luteolin, luteolin-7-O-glucoside acted as a more potent inducer of changes in phase II enzymes. Liver histopathology results were consistent with the mediator and enzyme results. CONCLUSION: Luteolin and luteolin-7-O-glucoside protect against GalN/LPS-induced hepatotoxicity through the regulation of inflammatory mediators and phase II enzymes.

The empty sella syndrome is characterized by obesity, frequent pregnancy, headache and high blood pressure, but its exact cause remains unknown. Usually the incomplete diaphragmatic sella has been considered as the cause of the empty sella syndrome, but some authors recently have suggested that the antipituitary antibody way be related to development of pituitary atrophy and the pituitary empty sella syndrome, and thus it may be clinically useful as screening test for the empty sella syndrome. We experienced two empty sella syndromes associated Graves disease and applied the antipituitary antibody as the diagnostic tool of the empty sella syndrome. But none of this two patients had antipituitary antibody and we report these cases with reviews of literatures.

This study was undertaken to analyze the displacement and stress distribution in the mandible according to the pulling directions during mandibular first molar cervical traction after mandibular second molar extraction. The 3-dimensional finite element method(FEM) was used for a mathematical model composed of 594 elements and 1019 nodes. An orthodontic force, 450gm, was applied to the each mandibular first molar in parallel, and below the occlusal plane by 7degrees and 25degrees and meet the midsagittal plane by 40degrees toward posterior direction. The results were as follows: 1. Mandibular teeth were displaced in more downward, posterior and lateral direction. Especially high stress was noted in case of parallel pull than in case of below the occlusal plane by 7degrees and 25degrees. 2. Mandibular first molar was moved bodily. 3. Generally, alveolar bone, mandibular body, ascending ramus and mandibular angle portion were displaced in downward, posterior and lateral direction. But coronoid process was displaced in downward, forward and lateral direction, and anterior and inner middle portion of condyle head and neck were displaced in downward, forward and medial direction, and posterior and outer middle portion of condyle head and neck were displaced in upward, forward and medial direction. 4. Maximum stress was observed at the condyle head and neck portion. With steeper direction of force, condyle head and neck showed more stress than parallel relation to the occlusal plane.

PURPOSE: In the present study, the incidence and risk factors of lens-iris diaphragm retropulsion syndrome (LIDRS) were evaluated. METHODS: Patients who underwent cataract surgery using phacoemulsification between June 2014 and December 2014 were included in the study. The preoperative ocular biometric and intraoperative surgical parameters were examined. The incidence of LIDRS and various risk factors were analyzed using an independent t-test, Pearson's chi-square test, and univariable and multivariable logistic regression analyses. RESULTS: Among 124 eyes of 124 patients, 100 (80.6%) had no LIDRS and 24 (19.4%) had LIDRS. LIDRS occurred in 13 of 31 vitrectomized eyes (41.9%) and 11 of 93 non-vitrectomized eyes (11.8%). Based on univariable analysis, age (odds ratio [OR], 0.920; p = 0.001), vitrectomized eye (OR, 5.038; p = 0.001), spherical equivalent (OR, 0.778; p < 0.001), axial length (OR, 1.716; p < 0.001), anterior chamber depth (OR, 3.328; p = 0.037), and 3.0 mm vs. 2.2 mm incision size (OR, 4.964; p = 0.001) were statistically significant risk factors associated with the development of LIDRS. Conditional multivariable logistic regression showed that vitrectomized eye (OR, 3.865; 95% confidence interval [CI], 1.201 to 12.436; p = 0.023), long axial length (OR, 1.709; 95% CI, 1.264 to 2.310; p = 0.001), and 3.0 vs. 2.2 mm incision size (OR, 3.571; 95% CI, 1.120 to 11.393; p = 0.031) were significant independent risk factors associated with LIDRS. CONCLUSIONS: LIDRS is a relatively common occurrence and was found to be associated with vitrectomized eye, long axial length, and larger incision size. Evaluating risk factors prior to cataract surgery can help reduce associated morbidity.

PURPOSE: To evaluate the clinical results of deep lamellar endothelial keratoplasty (DLEK) surgery in patients with bullous keratopathy. METHODS: Seven eyes of 7 patients diagnosed with bullous keratopathy were evaluated for pre- and postoperative visual acuity, refractive error, astigmatism, and corneal topographic results. Specular microscopy and corneal pachymetry was performed in order to evaluate the corneal endothelial cell status. Postoperative complications such as graft rejection, infection, glaucoma, and graft dislocation were also evaluated. RESULTS: Preoperative visual acuity improved from 0.006 (CF ~ 0.02) to 0.4 (0.1 ~ 0.5) at an average of 1.2+/-0.18 years of follow-up. Manifest refraction, topographic astigmatism, corneal endothelial cell density, and central corneal thickness at the final visit were 1.21+/-0.73D, 2.1+/-0.70D, 1304+/-682 cells/mm2, and 504+/-128 micrometer respectively. Two eyes (28.6%) developed graft rejection, one of which recovered after intensive steroid treatment. However, one patient (14.3%) underwent penetrating keratoplasty due to graft failure at 6 months postoperatively. Seven of 7 eyes were noted to have graft dislocation, all of which were repositioned and attached after air injection or suture. CONCLUSIONS: DLEK surgery is an effective alternative to conventional penetrating keratoplasty for bullous keratopathy patients because of fast visual recovery and low incidence of postoperative astigmatism.
