Recently, the bcl-2 and p53 protein have been recognized as important factors that is contributed to programmed cell death. The objective of this study was to evaluate the prognostic significance of bcl-2 and p53 protein expression in uterine cervical carcinoma. The expression of bcl-2 and p53 in 59 cases of uterine cervical carcinoma (stage IB to IIB) were surgically treated from January 1993 to June 1994. The expression of bcl-2 and p53 was examined by immunohistochemical method using formalin fixed paraffin embedded tissue specimens. The 48 cases were squamous cell carcinoma and 11 cases were adenocarcinoma. The results were as follows: 1. The expression rate of bcl-2 protein was 28.8%(17/59) and there was no significant correlaltion between the expression of bcl-2 protein and the clinicopathologic parameters (histologic type, grade, FIGO stage, cervical invasion depth, lymph node metastasis, parametrial invasion, tumor size, neoadjuvant chemotherapy response, recurrence, survival). 2. The expression rate of p53 protein was 32.2%(19/59) and there was no significant correlation between expression of p53 protein and the clinicopathologic parameters. 3. There was significant correlation between and expression of bcl-2 and p53 protein (P 0.05). In conclusion, bcl-2 and p53 protein are thought to be possible factors in the carcinogenesis of uterine cervical carcinoma and correlate with progression of it. But further study will be required to clarify the role of bcl-2 and p53 in carcinogenesis of the uterine cervix.

Cranial mononeuropathies, manifesting particulary as opthalmoplegia or facial palsy, are common entities in the dia-betic population. However, sequential multiple cranial neuropathies due to diabetes are much less common. It is often associated with other conditions such as a brain tumor or head trauma. A 61-year-old diabetic man presented with ptosis, opthalmoplegia, and facial palsy which were manifestations of multiple cranial neuropathies involving the left 3rd, 4th, 6th, and 7th cranial nerves throughout five weeks. The pupils were not involved. The neurologic evaluation included a CSF study and a brain MRI with MRA. None of them produced any significant results. Blink reflexes revealed evidence of a left facial nerve lesion. The blood glucose was strictly controlled and steroid therapy was administered. The ptosis of the patientanjx left eyelid improved during treatment and he was discharged after 13 days. In a follow-up examination 3 months after onset, focal neurological deficits including opthalmoplegia and facial palsy on the left side were greatly improved and barely noticeable.

OBJECTIVE: The purpose of this study was to review the clinicopathologic features, recurrent rate, survival rate and controversable issues in the treatment of the ovarian malignant germ cell tumors. PATIENTS AND METHODS: From August, 1991 to November, 1998 thirty-one patients with malignant germ cell tumors of the ovary treated in the department of obstetrics and gynecology, Kosin University Medical college, were eligible and assessable. Demographic characteristics, symptoms, signs, stage, tumor grade, mode of therapy and results of follow up were reviewed retrospectively. RESULTS: The patients with malignant germ cell tumor constituted 6.37% of all ovarian malignancies during this period. Histologic subtypes were 8 dysgerminoma(25.8%), 7 endodermal sinus tumor(22.6%), 10 immature teratoma(32.3%), 3 mixed germ cell tumor(9.7%), 3 choriocarcinoma(9.7%). The age of the patients ranged from 10 to 40 years (mean +/-S.D.; 24.26 +/- 7.51). The most common symptom was abdominal pain(38.7%). Most had stageI(18 cases, 58.0%) or stageIII(5 cases, 16.2%) diseases. All patients underwent surgery as the initial treatment, and nine patients received more than one operation. Postoperative adjuvant chemotherapeutic regimens were VAC, VBP, EP, BEP, EMA, and EMA CO. The mean follow up duration was 26.0(+/- S.D.; +/- 20.3) months. The 2-year and 5-year survival rate were 91.97%(+/- S.E.; +/- 0.05) and 86.86%(+/- S.E.; +/- 0.07).

Patients who have repaired cleft lip and palate generally undergo restriction of maxillary growth. Concave facial profile is often exhibited with relatively normalized mandible. Horizontal and sagittal deficiency of the maxilla could cause anterior and posterior crossbites. In growing patients, orthodontic and orthopedic treatment is acceptable with maxillary expansion and protraction. However, surgical approach has to be accompanied with orthodontic treatment in skeletally matured patients. We used SARPE and BSSRO to expand the constricted maxilla and retract the mandible in a patient who had cleft palate repaired in infancy. Through SARPE, orthodontic treatment and BSSRO, we sufficiently expanded the maxillla and improved facial profile.

Malignant tumor originated from external auditory canal (EAC) is very rare with an annual incidence of around 1 per million. Pathologically, squamous cell carcinoma is incidentally most common, and adenoid cystic carcinoma, basal cell carcinoma, and melanoma follow in decreasing order. Due to the rarity of malignant tumor of EAC, there is no widely accepted treatment modality yet. But basal cell carcinoma, known to be less aggressive tumor, can be removed with a minimal safety margin and have better treatment results. Recently we experienced a case of basal cell carcinoma in the EAC, confined in the cartilaginous portion of EAC, presenting with intermittent otorrhea for several years. The patient was treated with a sleeve resection of the EAC with a safety margin reconstructed with a split-thickness skin graft. No tumor recurrence or complication was noted in the first postoperative year.

To determine the usefulness of the Bosniak classification of cystic renal masses, the computed tomographic findings of 30 pathologically proven cystic renal masses were reviewed retrospectively. We categorized cystic renal masses utilizing the Bosniak classification without knowledge of the final pathologic diagnosis. There were 10 category I lesions, 3 category II lesions, 6 category III lesions and 11 category IV lesions. All category l and II lesions were benign. All category IV lesions were malignant. Among the 6 category III lesions, 5 were malignant. The other was benign lesion with hemorrhagic renal cyst. We concluded that computed tomography and Bosniak classification are useful in management of cystic renal masses.

Nucleolar organizer regions(NORs) contain coding genes for ribosomal RNA and contribute the regulation of cellular protein synthesis. AgNORs numbers correlate with growth fraction and have been reported the AgNORs counts may have a diagnostic and prognostic utility in other human tumors. We investigated the diagnostic usefulness of AgNORs staining technique as a discriminant for malignancy and assessed the value as a potential method for the estimation of cell kinetics. In addition. we compared the AgNOR counts with flow cytometric analysis of ploidy, S-phase fraction, proliferation index, and PCNA expression rate. There was a statistically significant difference of AgNORs counts between superficial bladder tumor and invasive bladder tumor. But there was no relationship between the mean number of AgNORs per nucleus and histological grade. DNA aneuploid group was associated with higher AgNORs counts than diploid group, but the difference was statistically insignificant. The mean number of AgNORs per nucleus had significant relationship to SPF(r=0.43, p<0.05) and PI(r=0.41, p<0.05.) We concluded that this method alone does not offer a reliable histological discriminant for malignancy. Further studies are needed to confirm that AgNORs counting is a useful method for evaluating the proliferative activity and this technique may serve as a prognostic factor additional to the current histopathological grading criteria of the bladder cancer.
