Glassy cell carcinoma is a histologic subtype of cervical cancer with distinct pathologic features and it has an aggressive biologic course. It was first described by Glucksmann and Cherry in 1956 as a poorly differentiated adenoquamous carcinoma and commented on its poor prognosis, unresponsiveness to traditional modes of therapy, and often associated with pregnancy. The characteristic histologic features are defined as follows: 1) cells with a moderate amount of cytoplasm resembling ground glass, 2) a fairly distinct cell membrane that stains with eosin or PAS, 3) large nuclei with prominent nucleoli. We present two cases of glassy cell carcinoma of the cervix successfullyl treated by neoadjuvant chemotherapy and radical hyterectorny, with a brief review of literatures.

The incidence of intracranial complications of otitis media, including lateral sinus thrombophlebitis, has been significantly reduced since the advent of antibiotics. This entity is rarely encountered in clinical practice, and delay in its diagnosis and institution of appropriate therapy may lead to serious, or even fatal, consequences. The signs and clinical course of lateral sinus thrombophlebitis are non-specific and the final diagnosis rests upon radiological investigations including CT-scans and MRI. We have experienced a case of middle fossa and posterior fossa epidural abscess formation, lateral sinus thrombophlebitis that has developed secondary chronic otitis media with cholesteatoma in a 47 year-old female patient. We report this case which was successfully treated by middle fossa dura and posterior fossa dura drainage, lateral sinus thrombectomy with open mastoidectomy.

A 63-year-old woman developed left leg weakness, bilateral sensorineural hearing loss and headache. Brain MRI showed a hypointense rim on the surfaces of the cerebellum, brainstem, and cerebral cortex indicating superficial siderosis. Further examination showed an intramedullary ependymoma at the level of T12-L2. We report a patient with a spinal cord ependymoma resulting in superficial siderosis of the central nervous system.

BACKGROUND: Epithelial-mesenchymal transition (EMT) is critical for morphogenesis during embryonic development and is also implicated in the conversion of early-stage tumors into invasive malignancies. Recently, Twist has been identified to play an important role in EMTmediated metastatic progression of several types of human cancer. The present study examined the expression of Twist and evaluated its clinicopathologic significance in urothelial carcinoma of upper urinary tract. METHODS: Immunohistochemical staining for Twist expression was performed on 70 upper urinary tract urothelial carcinomas (UUT-UCs) using tissue microarray. RESULTS: Immunohistochemical staining for Twist was positive in 31/70 cases (44.3%) of UUT-UCs. Twist expression was associated with high-grade and advanced-stage (ISUP grade, p<0.01; stage, p=0.045). The patients with Twist positive-tumors revealed lower disease free survival rate than those with Twist negative-tumors (p<0.01). The overall survival for patients with Twist positive-tumors was slightly worse than the patients with Twist negative- tumors, but the difference was not statistically significant (p=0.12). CONCLUSION: Our results suggest that Twist is a novel marker for advanced UUT-UC.

To characterize the clinical manifestations, and histologic features of CNS lymphoma in immunocompetent patients, we collected 15 cases of biopsy proven primary CNS lymphoma. Evidences of systemic lymphoma, HIV infection, and immune-compromising diseases were absent at the diagnosis. Brain MRI had been taken before radiation or chemotherapy, and pathologic specimens were classified according to working formulation and some cases underwent immunological marker studies. Mean duration of illness was 1. 8 months, mild CSF protein elevation(mean=58mg%) was observed in 5 of 6 patients, CSF cytology was positive in 2 of 7, and the recurrence rate was 69%. In MR imaging, tumor size was variable, and 5 patients had multiple lesions at diagnosis. All patients showed homogeneous(87%) or heterogeneous(13%) gadolinium enhancement, and secondary tumor change was shown in I case. The tumor had high tendency in abutting on CSF space(60%), and there was no relationship between histologic types and MR imaging I s. Classified by working formulation, the intermediate grade lymphomas(diffuse large cell and small cell cleaved types) were 14 out of 15(93%) and I showed low grade(small lymphocytic). B-cell lymphoma was 8 out of 9, and T-cell was only 1. As compared with the previous reported pathologic data of AIDS-related CNS lymphoma, the histology of lymphoma in immunocompetent patients were less malignant than those related to AIDS and immune-compromised patients.

In order to explore the existence and distribution of phospholipase (PLC) isozymes in the rat retina, immunohistochemical staining was applied using monoclonal antibodies against PLC isozymes (PLC beta; K92, PLC gamma; D7, F7, PLC delta; R32, S11). For immunohistochemical detection, avidin-biotin peroxidase complex (ABC) method was performed on frozed tissue sections of rat retina. Our study showed that PLC isozymes have particular distributional patterns in the retina. Namely, PLC beta is broadly distributed in the outer and inner segments of photoreceptor cell layer, nuclear layer and ganglion cell layer. PLC gamma is mainly appeared in the nerve fiber layer, ganglion cell layer and inner nuclear layer. PLC delta is confined only in the ganglion cell layer. These results clearly demonstrate the PLC isozymes may have their own role in the transduction of light pathway in the retina. However, further studies will be required to verify theirs precise role in the photoreception.

Previous single-photon emission computed tomography (SPECT) studies have demonstrated decreased (1231)beta-CIT (2beta-carbomethoxy-3beta(4-iodophenyl) tropane) striatal binding in Parkinson's disease (PD) patients. The present study extends our previous work by examining SPECT measures of (1231) beta-CIT binding in a larger group of PD patients with varying disease severity. Forty-six L-dopa-responsive PD patients(Hoehn-Yahr stage 1-3) had either a total of 15 SPECT scans over a 24 hr period or two scans at 12 hr and 24 hr after injection of (1231) beta-CIT. (1231) beta-CIT binding in the striatum was estimated using two indices: the specific-to nonspecific binding ratio, calculated as (striatal-cerebellar)/cerebellar radioactivity (specific binding ratio: SBR) at 24 hr postinjection as well as at its peak, which occurred at 12-24 hr postinjection; and the binding potential, the ratio of the rate constant of binding to the dopamine (DA) transporters (k3) to that of dissociation from the DA transporters (K4), as calculated by tracer kinetic modeling. The mean SBR at 24 hr postinjection, the mean peak SDR, and the mean binding potential in the striatum were all significantly correlated with Hoehn-Yahr stage, total store of UPDRS, motor score of UPDRS, and activities of daily living score of UPDRS. There were significant correlations between the sum of lateralizing UPDRS subscales (tremor, rigidity, bradykinesia) calculated for each individual limb and the SPECT measures of [123I]beta-CIT binding in the contralateral striatum. There were excellent correlations among the peak striatal SBR, the stiiatal SBR at 24 hr postinjection, and the binding potential. The results indicate that [123I]beta-CIT may be a useful marker of disease severity in PD. Additionally, the simple tissue ratio at 24 hr postinjection may be acceptable for the assessment of [123I]beta-CIT binding in PD, making repeated scanning and complicated modeling procedures less necessary. [123I]beta-CIT SPECT may be clinically useful for the early diagnosis and serial monitoring of PD.

Purpose: This study aimed to identify independent predictors of favorable outcomes associated with emergent carotid artery stenting (CAS) in patients with acute anterior circulation stroke. Materials and Methods: This study included 93 patients with acute stroke who underwent emergent CAS to treat stenoocclusive lesions in the cervical internal carotid artery (ICA) within 6 hours of the onset of the associated symptoms. Data were compared between patients with and without favorable outcomes. The independent predictors of a favorable outcome were determined via logistic regression analysis (modified Rankin Scale 0–2 at 90 days). Results: Intracranial tandem occlusion was noted in 81.7% of patients (76/93) among which (76/93), 55 of whom underwent intracranial recanalization therapy. Intracranial reperfusion was successful in 74.2% (69/93) and favorable outcomes were noted in 51.6% of patients (48/93). The mortality rate was 6.5% (6/93). In logistic regression analysis, diffusion-weighted imaging-Alberta Stroke Program Early CT Score [odds ratio (OR), 1.487; 95% confidence interval (CI), 1.018–2.173, p = 0.04], successful reperfusion (OR, 5.199; 95% CI, 1.566–17.265, p = 0.007), and parenchymal hemorrhage (OR, 0.042; 95% CI, 0.003–0.522, p = 0.014) were independently associated with a favorable outcome. Conclusion Baseline infarct size, reperfusion status, and parenchymal hemorrhage were independent predictors of favorable outcomes after emergent CAS to treat stenoocclusive lesions in the cervical ICA in patients with acute anterior circulation stroke.
