The cell cycle is composed of a series of steps which can be negatively or positively regulated by various factors. p53 gene aberrations are common in human malignancies, and recent studies suggest that in cervical carcinoma p53 function is inactivated either by complex formation wilh human papilloma virus (HPV) E6 product or by gene mutation. To study the expression of p53 gene in the cervical cancer and cervical intraepithebal neoplasia, immunohistochemistry for the p53 protein was done in the 47 cases of squamous cell carcinoma, 6 cases of adenocarcinoma and 32 cases of cervical intraepithelial neoplasia. I. The p53 protein was detected in the 31% of cervical intraepithelial neoplasia (10/32 cases). 2. The p53 protein was detected in the 55% of invasive cervical cancer (29/53 cases). 3. By the histologic type of cervieal cancer, the p53 protein was detected in the 57% of squamous cell carcinoma (27/47 cases) and 33% of(2/6 cases) adenocarcinoma. The p53 protein wes more frequently detected in the squamous cell carcinoma than in the adenocarcinoma. 4. By the staging in cervical cancer, the p53 protein was detected in the 31% of stage 0, 50% of Stage Ia, 50% of stage I b, 75% of IIa and 50% of stage II b.

A 50-year-old man with a 20-year history of migraine with aura was admitted due to a headache followed by right hemiplegia and speech disturbance. However, there were no abnormalities on brain MRIs and EEG at that time. His hemiparesis continued for one month. We report on a case of persistent hemiplegia and speech disturbance as migraine aura without an evidence of infarction on brain MRI.

Fibroadenoma is a rare lesion of the vulva. It has been proposed that the origin of the tissue is either ectopic breast tissue or vulvar mammary-like glands (MLG). We report a case of vulvar fibroadenoma in a 33-year-old woman with a right vulvar mass presenting clinically as vulvar cyst. The cut surface of the tumor showed a white and homogenous appearance that was 2.5 cm in maximum dimension. Microscopically, the lesion was well-circumscribed but non-encapsulated. It revealed nodular, glandular and stromal proliferation, consistent with fibroadenoma of breast. Immunohistochemical staining for the estrogen receptor and progesteron receptor revealed nuclear positivity in the epithelium. Smooth muscle actin confirmed the presence of a myoepithelial cell layer. Staining for pancytokeratin showed epithelial cytoplasmic positivity.

BACKGROUND: The aim of this study was to investigate the feasibility and efficacy of emergent carotid artery stenting (CAS) for occlusion or high-grade stenosis of the internal carotid artery (ICA) in patients with acute ischemic stroke. METHODS: From November 2004 to May 2007, 17 patients admitted to the hospital within 12 hours of symptom onset with occlusion or a high-grade stenosis of the proximal ICA underwent emergent CAS. We analyzed risk factors, imaging findings, functional outcome scales, and peri-procedural complication. The outcome was measured by the modified Rankin scale (mRS) 3 months later and classified into good (mRS score of 0 to 2) or poor (mRS score of 3 to 6). RESULTS: All patients were recanalized successfully. The median National Institutes of Health Stroke Scale (NIHSS) score was 12.6 (range 4 to 24) just before the emergent CAS, which decreased to 9.4 and 8.2 at 1 day and 7 days after the stenting. Three months later, 12 patients showed good outcome while three had poor outcome and two of them died. Two patients (11.8%) exhibited symptomatic hemorrhagic transformation following the emergent CAS. Smoking status, and initial and immediate post-procedural NIHSS scores were associated with the outcome. CONCLUSIONS: Emergent CAS is a feasible and effective method in acute treatment of selected stroke patients with steno-occlusion of the proximal ICA.

Adenomyoma is a benign tumor composed of smooth muscle and benign endometrium. These tumors typically originate within the uterus. An extrauterine adenomyoma is a rare entity. Cystic degeneration of adenomyoma is also very rare case. We report a case of huge extrauterine endometrioid-type adenomyoma with cystic change with brief review of literature.

PURPOSE: To evaluate the significance of collateral veins, as seen on chest CT, in the diagnosis of superiorvena cava obstruction. MATERIAL AND METHOD: We retrospectively reviewed the records of 81 patients in whomcollateral veins were seen on chest CT. On spiral CT(n=49), Contrast material was infused via power injector, andon conventional CT(n=32), 50ml bolus infusion was followed by 50ml drip infusion. Obstruction of the SVC wasevaluated on chest CT ; if, however, evaluation of the SVC or its major tributaries was difficult, as in fivecases, the patient underwent SVC phlebography. Collateral vessels were assigned to one of ten categories. RESULT: On conventional CT, the common collaterals showing statistically significant difference between the two groupswere the jugular venous arch in the group with venous obstruction(n=6/15, 40.0%), and around the back and scapula(n=15/17, 88.2%) and paravertebral system(n=12/17, 70.6%) in the group without venous obstruction. On helical CT,the most common collaterals were around the back and scapular (n=9/14, 64.3%; n=26/35, 74.3%, respectively) andthe paravertebral system (n=9/14, 64.3%, n=22/35, 62.9%, respectively) in both groups, with or without venousobstruction. No collateral showed a statistically significant difference between the two groups. CONCLUSION: Onconventional CT, the jugular venous arch is the only collateral vessel to predict SVC obstruction ; on spiral CT,however, collateral vessels are not helpful in the diagnosis of SVC obstruction, but are a nonspecific finding.

Vasoplegic syndrome occurs in 8~10% of patients following cardiac surgery, and this happens in part because of inducing the inflammatory response. Nitric oxide and guanylate cyclase play an important role in this response, and this is associated with increased morbidity and mortality. For our case, we administered methylene blue (MB), an inhibitor of guanylate cyclase, early after performing cardiopulmonary bypass in a patient with vasoplegic syndrome. The patient recovered immediately after MB administration and maintained an optimal blood pressure without the aid help of any vasopressors.

We report here on a rare case of adrenal paragonimiasis that presented with an adrenal incidentaloma. A 52-year-old male presented with fatigue and weight loss. The laboratory findings revealed eosinophilia (8.5%) and an increased eosinophil count (910/microL). The computed tomography scan showed 6.5 x 5 cm sized multilocular cystic mass in the right adrenal gland, which was non-functioning, and cystic lesions with variable sizes were also noted in the abdominal cavity. On the surgical field, whitish patches were spread out in the peritoneum, the omentum, the dome of the liver and the diaphragm. The right adrenal gland was replaced by a cystic mass filled with mucopurulent creamy materials. The pathologic findings revealed numerous eggs of Paragonimus spp. Also, the ELISA was positive for IgG paragonimus antibody. The adrenal gland can become infected by various microbial pathogens, including parasites, although it is relatively uncommon. However, in the case of a cystic adrenal mass with accompanying eosinophilia in an endemic area, clinicians should consider the possibility of parasitic infection.

Granulosa cell tumors of ovary are rare neoplasms, which account for 2~5% of all ovarian malignancies. Ovarian granulosa cell tumors are often associated with endometrial hyperplasia or carcinoma. The endometrial carcinoma is thought to occur under the influence of the estrogen receptor pathway and is typically a low-grade endometrioid adenocarcinoma. We present a case of granulosa cell tumor of the ovary and synchronous endometrial carcinoma that were managed with laparoscopically assisted vaginal hysterectomy and bilateral salpingo-oophorectomy, with brief review of literature.
