Cellular oncogenes are expressed as an intrinsic part of the transformed or neoplastic phenotype. More than 60 of the known cellular oncogenes play a specific role in normal cellular development and differentiation. To examine the correlation between ras oncogene expression and the development of cervical cancer, this study investigated the reactivity of cervical intraepithelial neoplasia(CIN) and carcinoma of the uterine cervix by using anti-ras P21 mouse monoclonal antibody. The expression of ras oncogene significantly increased with the grade of malignancy from 11% in severe dysplasia, 30% in carcinoma in situ, 43% in microinvasive carcinoma, to 53% in invasive cancer. The expression of ras oncogene was not correlated with histologic type, tumor size, and nodal status of cervical cancer. It was concluded that expression of ras oncogene is related to early phase of carcinogenesis and tumor invasion of carcinoma of the uterine cervix.

Though the incidence of paragonimiasis has been remarkably decreased since 1970, it is still not a rare disease in Korea. Major problems in the diagnosis of pulmonary paragonimiasis on chest radiography are its differentiation from pulmonary tuberculosis and lung cancer. Chest radiographic findings have been described in detail, but little have been reported on CT findings. We reviewed CT findings of 10 patients with pulmonary paragonimiasis. The characteristic CT findings were similar to those on chest radiography, such as air-space consolidation (70%), nodular mass (50%), pleural effusion (40%), cystic lesion (30%), small low density within the mass (30%), linear density (20%), pneumothorax(20%), and burrow track (20%). CT depicted the cystic lesions and the burrow tracks more clearly and showed the small worm-retaining cysts within the mass that were not detectable on chest radiography. In conclusion, all of these CT findings are useful in the diagnosis of pulmonary paragonimiasis especially when differentiation from tuberculosis or lung canceris difficult on chest radiography.

Gastritis cystica superficialis (GCS) is a rare lesion which is characterized by glandular hyperplasia with regeneration and degeneration in the mucosa and muscularis mucosa. Recently, GCS is revealed as precancerous lesion, but most report has been associated with those found at the site of a gastroenterostomy. So, we report two cases with GCS who had not previous gastric surgery. A 45-year-old woman visited for epigastric discomfort and another 4Q-year-old woman for epigastric pain. They had not undergone any gastric surgery. The gastroscopy discovered one polyp on anterior wall of greater curvature, upper body and another polyp in the center of the fold of greater curvature, lower body. We removed it by snare polypectomy and the histologic finding showed the character of GCS.

Purpose: We present a case of alitretinoin-induced pseudotumor cerebri.Case summary: A 28-year-old woman presented with a 1-month history of bilateral papilledema and intermittent blurred vision in the left eye. She had been taking alitretinoin (9-cis-retinoic acid, AlitocⓇ; GlaxoSmithKline) for atopic dermatitis and hand eczema. Although visual acuity remained intact in both eyes, mild central scotoma was detected bilaterally. Optical coherence tomography revealed increased retinal nerve fiber layer thickness in both eyes. Enhanced magnetic resonance imaging revealed no abnormalities except for bilateral flattening of the posterior sclera. Cerebrospinal fluid exhibited an elevated opening pressure (220 mmH2O) and a normal composition. Following the discontinuation of alitretinoin, the intermittent blurred vision, papilledema, and central scotoma improved significantly within 2 months. Conclusions Alitretinoin use should be monitored carefully for a potential development of pseudotumor cerebri, particularly in patients with pre-existing risk factors.mmH2O) and a normal composition.

PURPOSE: The authors applied fetal stabilization and evaluated its efficacy as a therapeutic modality in the management of several congenital anomalies that can lead to perinatal respiratory distress, such as a congenital diaphragmatic hernia (CDH), large cervical lymphangioma or gastroschisis, etc. METHODS: Between Oct. 2000 and Dec. 2004, 12 newborns, with a congenital diaphragmatic hernia or gastroschisis, were observed and fetal stabilization was applied to 4 neonates. Their clinical characteristics were then retrospectively reviewed. The protocol of this procedure was as followed, (1) monitoring of the fetal respiratory movement and heart beat using Doppler ultrasonography, (2) the intravenous administration of morphine (20 to 30 mg) and diazepam (5 mg) to the mother, (3) proceed to a cesarean section when any interruptions in the fetal movement were confirmed, (4) an intravenous injection of a pancuronimum (0.5 mg) through the umbilical vein, (5) an immediate tracheal intubation before disruption of the placenta, (6) clamping of the umbilical cord, (7) attempt a mechanical ventilation after delivery, (8) maintain percutaneous intravenous catheterization (PIC) and (9) evaluation of the neonate. RESULTS: Of the 10 neonates with a CDH and the 2 with gastroschisis, fetal stabilization was applied to 3 CDH and 1 gastroschisis neonates, respectively. The survival rates were 85.7% that of conventional therapy, 66.7% for fetal stabilization in the CDH neonates and 100% for those with gastroschisis. Relatively, in those with a CDH where fetal stabilization was applied, large defects were observed and they were diagnosed at an earlier period, which could affect the mortality. CONCLUSION: In our experience, fetal stabilization seems to be useful as another alternative therapeutic modality for the control of respiratory distress in the management of a CDH and gastroschisis. However, further experiences with more clinical results will be required
