OBJECTIVE: The object of this study was to compare the diagnostic accuracy of a sonographic morphologic scoting system, the serum CA-125 assay, and a combination of both in patients undergoing laparotomy for a clinically diagnosed adnexal mass. METHODS: In 129 consecutive patients, the morphology of the mass was evaluated and scored by the morphologic scoring system of Sassones using transabdominal or transvaginal sonography and blood samples were obtained for CA-125 assay before planning surgery, RESULTS: The sensitivity of the sonographic morphologic scoring system was 90.6%, the specificity 84.5%, the positive predictive value 65.9%, and the negative predictive value 96.5%, compared with 68.8, 77.3, 50.0, and 88.2% for CA-125 and 96.9, 66.0, 48.4, and 98.5% for the two tests combined, respectively. Only one case of serous borderline ovarian tumor was missed when the two tests were combined. The sensitivity and mean value of the serum CA-125 increased with the stage of ovarian cancer. CONCLUSION: The combination of sonographic findings with a serum CA-125 assay was more sensitive, but less specific, than sonography or the serum CA-125 assay alone in predicting the malignancy of an adnexal mass. The serum CA-125 level generally reflected the stage of the disease. We think that it is reasonable to check the serum CA-125 only in cases of ovarian malignancy diagnosed by sonography.

PURPOSE: This treatment planning study was undertaken to evaluate the impact of beam angle configuration of intensity-modulated radiotherapy (IMRT) on the dose of the normal liver in hepatocellular carcinoma (HCC). MATERIALS AND METHODS: The computed tomography datasets of 25 patients treated with IMRT for HCC were selected. Two IMRT plans using five beams were made in each patient; beams with equidistance of 72degrees (Plan I), and beams with a 30degrees angle of separation entering the body near the tumor (Plan II). Both plans were generated using the same constraints in each patient. Conformity index (CI), homogeneity index (HI), gamma index, mean dose of the normal liver (Dmean_NL), Dmean_NL difference between the two plans, and percentage normal liver volumes receiving at least 10, 20, and 30 Gy (V10, V20, and V30) were evaluated and compared. RESULTS: Dmean_NL, V10, and V20 were significantly better for Plan II. The Dmean_NL was significantly lower for peripheral (p = 0.001) and central tumors (p = 0.034). Dmean_NL differences between the two plans increased in proportion to gross tumor volume to normal liver volume ratios (p = 0.002). CI, HI, and gamma indices were not significantly different for the two plans. CONCLUSION: The IMRT plan based on beams with narrow separations reduced the irradiated dose of the normal liver, which would allow radiation dose escalation for HCC.

Implant fixed prosthesis for the complete edentulous maxilla provides significant benefits in the aspects of functions and esthetics compared with the conventional denture. Implant supported fixed prosthesis are totally supported by implant, and thus stabilizes the prosthesis to the maximum degree as possible. Also, the improved retention and stability of fixed prosthesis enhance patients' psychological and psychosocial health. This clinical presentation describes a maxillary full arch implant-supported fixed prosthesis in complete maxillary edentulous patient who showed vertical and horizontal alveolar bone resorption in the anterior ridge. To rehabilitate the esthetics and proper lip support, the zirconia framework was fabricated and the pink porcelain was veneered to reproduce the natural gingival tissue. After 9 months of follow up, the restorations were maintained without complications and the patient was satisfied with the restoration both functionally and esthetically.

Purpose:
Granular corneal dystrophy type 1 (GCD1) is a genetic disorder characterized by grayish-white granular deposits in the corneal stroma, typically manifesting before age 10. The specific characteristics of GCD1 in the Korea population remain insufficiently described. This study investigated the morphological features of GCD1 corneas with confirmed genetic mutations in this population.
Methods:
Medical records of GCD1 patients with the R555W mutation confirmed through transforming growth factor β induced (TGFBI) gene testing on oral epithelium or blood samples from 2005-2022, were analyzed. Corneal photographs obtained using a slit lamp biomicroscope were also examined.
Results:
The study group included 11 males and 19 females with an average age of 35.7 years, ranging from 3-70 years. All participants were heterozygotes. In 28 individuals (56 eyes, representing 93.3% of the total), there were signs of corneal deposit detachments, known as “drop-off”, observed in patients aged 6 years and above. Surface deposits reemerged at the peripheral margin of previous locations and expanded toward the center. The number and shape of opacities significantly changed with age, showing cycles of deposition and shedding. There were variations in the severity of opacities within the same family, particularly with advancing age, and distinct opacities extending into deeper stromal layers.
Conclusions
This study outlines the morphological characteristics of corneas in Korean GCD1 patients, based on corneal photograph analysis. These findings provide a basis for future comparative studies with GCD2 and may aid rapid clinical diagnosis based on clinical findings, prior to genetic testing confirmation.

OBJECTIVES: To determine changes in the incidence and pattern of eclampsia in Il Sin Christian Hospital over a 46-year period. METHODS: Information was collected from medical records of the 1910 eclamptic patients among 233,613 deliveries in Il Sin Christian Hospital from Jan. 1 1953 to Dec. 31 1998. Incidence, presentation, and management of eclampsia were reviewed retrospectively, and maternal mortality rate and perinatal mortality rate were calculated. Statistical analysis was done by Chi-squared and Fisher's exact test through two by two tables looking at relative changes between each study period. RESULTS: The overall incidence of eclampsia was 81.8 per 10,000 deliveries. The incidence of eclampsia had increased from 137.3/10,000 in 1953-1962 to 278.4/10,000 in 1963-1972, but the rate had reduced to 6.5/10,000 in 1993-1998. There was a statistically significant fall in the rate of eclampsia every decade between 1973 and 1992, but there has been steady decrease in the last study period. Convulsion occurred antepartum in 54% of patients, intrapartum in 29% and postpartum in 17%. With the reduction in the proportion of antepartum eclampsia, there has been a relative increase in that of intrapartum and postpartum eclampsia. Maternal death occurred in 59 cases among eclampsia, and maternal mortality rate was 3.1%. Maternal mortality rate had significantly decresed from 11.1% in 1953-1962 to 3.8% in 1963-1972, and there has been no maternal death from eclampsia since 1986. Postpartum eclampsia had increased death risk compared with antepartum or intrapartum eclampsia. There were 280 cases of perinatal death and overall perinatal mortality rate was 144.1 per 1000 deliveries. There was a significant decrease in the rate from 243.2/1000 in 1953-1962 to 141.5/1000 in 1963-1972, but the rate has risen steadily since 1983. CONCLUSIONS: With the improvement in antenatal care and management of eclampsia, the incidence of eclampsia and its associated maternal mortality has decreased over the last 46 years. But eclampsia still remains a significant complication of pregnancy with high maternal and perinatal mortality.

We report a case of primary cutaneous cryptococcosis on the left knee of a 67 year-old woman. She had a large ulcerated and indurated plaque with yellowish purulent exudates on her left knee. A histopathological examination from the lesion showed numerous encapsulated, round spores. Cultures from the lesion showed the presence of Cryptococcus neoforrnans. This may have resulted from an immunosuppressive state due to long-term use of oral corticosteroids.

9.Surgical Reconstruction of Nasal Alar Deformities.
Journal of Rhinology 2017;24(2):65-73
Reconstruction of the nasal alar may be challenging due to the complex nature of multiple cosmetic units and functional considerations, including maintenance of valvular competency. Reconstructive options include various flaps or graft repairs, depending on the subunit involvement and the size of the defect. Linear closures may be suitable for small defects, while bilobed flaps, melolabial flaps, and forehead flaps may be considered for moderate to large defects involving partial and full-thickness defects of the ala.

To investigate cellular proliferation pattern of pterygial tissue, eleven paraffin sections through two normal conjunctiva, six primary and three recurrent pterygia were studied immunohistochemically by finding epithelial cells and subepithelial fibroblasts staining patterns as defined by monoclonal antibody for proliferating cell nuclear antigen(PCNA). The results showed similar epithelial cellular proliferation patterns in normal conjunctiva, primary and recurrent pterygia. But scattered patches of fibroblasts in subepithelial connective tissue staining positive with PCNA were found only in recurrent pterygium. Our results suggest that primary pterygium is not a disorder of excess cellular proliferation, but a proliferation of fibroblasts in subepithelial connective tissue have a role in pathogenesis of recurrent pterygium.
