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.

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.

PURPOSE: Tumor downstaging from preoperative chemoradiation has been associated with an increased probability of a sphincter-saving procedure and with improved local control and survival rate. We observed the effect and the prognostic value of pathologic tumor downstaging, including complete pathologic response to preoperative concurrent chemoradiation, resectability, sphincter-saving rate, disease- free survival, and overall survival in locally advanced rectal cancer patients. METHODS: From January 2000 to December 2003, we recruited a total 78 patients with computed tomography stages II and III rectal cancer which was treated by using preoperative concurrent chemoradiation; all patients had a radical resection with total mesorectal excision. Surgical resection was performed 6 to 8 weeks after completing the radiation therapy. The average follow up was 25.40+/-13.64 months. RESULTS: The number of patients according to CT stage before preoperative chemoradiation was 39 (II) and 39 (III). Tumor downstaging occurred in 51 (65.4%) patients, including 11 (14.1%) patients who had a complete pathologic response. Tumor size, radiation dose, and clinical stage were associated with tumor downstaging in the univariate analysis. None of the clinical or pathologic variables was associated with a complete pathologic response. The overall resectibality was 100%. The number of sphincter-saving procedures were 61 (78.2%). Recurrence occurred in 17 (21.8%) patients: local recurrence in 4 (5.1%) and distant metastasis in 13 (16.7%). None of the patients with a complete pathologic response recurred. Recurrences were 3 (17.6%)/7 (22.6%)/7 (36.8%) for pathologic stages I/II/III. Recurrence was more common among younger patients (P <0.05). Patients in the complete pathologic response group had more favorable disease-free survival compared with other group (yp stage I, II, III) (P=0.026). CONCLUSION: Preoperative concurrent chemoradiation for locally advanced rectal cancer seems to afford some potential advantages: high tumor response, resectability, and feasible sphincter preservation, and even a complete pathologic response. A complete pathologic response to preoperative chemoradiation is associated with an improved disease-free survival.

The aim of the present study is to verify the functional and anatomical neural pathways which innervate the urinary bladder in the central nervous system of the rat. To identify the functional neural pathway, the urinary bladder was stimulated by infusing formalin for 2 h. Then, brain and spinal cord were dissected out and immunohistochemistry was done by using anti-c-fos antibody. Many c-fos immunoreactive (IR) neurons were identified in the telencephalic cortical areas and in several brainstem nuclei, which are known mostly to be related with urinary bladder. In the spinal cord, a number of c-fos IR neurons were found in the lamina I, IIo, dorsal gray commissure, sacral parasympathetic nucleus. To identify the anatomical neural pathway of the urinary bladder, Pseudorabies virus (PRV) was injected into the wall of urinary bladder and was identified with anti-PRV by using immunohistochemistry. Most PRV labeled neurons were found where c-fos IR neurons were identified and few of them were also in the areas where c-fos IR neurons were not found, e.g., prefrontal cortex, agranular insular cortex, and subfornical organ. In the spinal cord, PRV labeled cells were found all over the gray matter. The present study presents morphological evidence demonstrating the supraspinal areas are related with the neural control of the urinary bladder and most functional neural pathway of the urinary bladder is well consistent with the anatomical neural pathway except in some telencephalic cortical areas.

PURPOSE: Although indications for abdominoperineal resection (APR) are decreasing due to the widespread of sphincter-saving procedures, APR is still the mainstay in the treatment of rectal cancer. The purpose of this study is to demonstrate the appropriateness of laparoscopic APR in terms of oncologic parameters. METHODS: From January 1984 to December 2003, 110 patients with a rectal adenocarcinoma who underwent APR were involved in this study. The data were grouped according to five main items: 1) patient demographic data, 2) operative procedure, 3) gross tumor findings, 4) pathologic tumor findings, and 5) perioperative treatment. Each item was subdivided by factors that could influence the oncologic results, and univariate analyses were performed. Thereafter, a multivariate analysis was performed with those factors considered statistically significant. RESULTS: The mean follow-up period was 106.01+/-9.98 months, the local recurrence rate was 23.6%, and distant metastasis rate was 31.8%. The five-year survival rate was 58.1%, and the ten-year survival rate was 51.1%. Multivariate analysis after univariate analyses showed that independent prognostic factors influencing local recurrence were preoperative CEA level, T-stage, and preoperative radiation therapy. Factors influencing distant metastasis were preoperative CEA level, N-stage, and preoperative radiation therapy. Univariate analysis showed that the laparoscopic approach was beneficial in terms of local recurrence; however, with the multivariate analysis, this was not statistically evident. Prognostic factors influencing long-term survival in the multivariate analysis were preoperative CEA level, stage, and perineural invasion. CONCLUSIONS: Laparoscopic APR was not significantly different from an open procedure in terms of oncologic outcomes. In the near future, a randomized prospective multicenter trial should tell us which approach is more beneficial.
