OBJECTIVE: Internal carotid artery (ICA) trunk aneurysms are rare constituting about 0.9 to 6.5% of all ICA aneurysms. They may arise from medial, lateral, ventral (posterior) or dorsal (anterior) walls of ICA. The most frequent site of origin is dorsomedial, followed by dorsal, dorsolateral and ventromedial wall. ICA dorsal wall aneurysms can be divided into the saccular type and blister type, which have different shapes, wall histological features and surgical tactics. The authors report an analysis of 27 cases of ICA trunk aneurysms treated with surgical clipping or GDC embolization. METHODS: Of 145 cases of ICA aneurysms from May 1998 to December 2005, we found 27 cases (17.5%) of such unusual aneurysms located at nonbranching sites of the intradural ICA. Features of neuroimagings and medical records were analyzed. RESULTS: Out of 27 aneurysms, 10 were located at ICA dorsal wall, 8 aneurysms were developed at ICA medialwall. Seven aneurysms originated from ICA ventral wall. Seven cases presented with subarachnoid hemorrhage and 20 cases were found unruptured. Two patients had blister-like aneurysm, and the others had saccular aneurysms. All patients were treated successfully with microsurgical clippings or GDC embolization. Microsurgical clipping were performed in 14 cases and among them, removal of anterior clinoid process was done in 12 cases. Eleven aneurysms were occluded with detachabel coil. Two patients underwent balloon occlusion of ICA. Blister aneurysm was clipped including a portion of the normal ICA wall. Good outcomes were obtained in 25 patients, and two patients were dead. CONCLUSION: ICA trunk aneurysms are developed at any site of ICA circumference. Therefore we consider a variety of treatment strategies. On clipping of aneurysms at proximal ICA trunk, removal of anterior clinoid process is important. Endovascular treatment may be good an alternative. However, surgical treatment is essential for blister like aneurysms.

PURPOSE: Intraductal papilloma (IDP) is a benign breast disease with malignant potential, for which complete surgical excision is usually recommended. The aim of the present study was to investigate predictive factors for upgrading patients with a benign papillary lesion (BPL). METHODS: This study was an observational study using a prospectively collected cohort. In total, 13,049 patients who underwent a core needle biopsy (CNB) for a breast lesion between January 2009 and May 2015 were enrolled. We reviewed all patients with pathologically confirmed BPL from a CNB. RESULTS: Surgical treatment was performed for 363 out of a total of 592 lesions. According to the pathological differences, the lowest upgrade rate was shown in IDP without atypia (without atypia, 6.0%; with atypia, 26.8%; papillary neoplasm, 31.5%; p<0.001). The univariate analysis showed that, in IDP without atypia, the age at diagnosis, size of BPL on ultrasonography, and density on mammography were associated with upgrading. The multivariate analysis revealed that age >54 years and lesion size >1 cm were significantly associated with upgrade to malignancy (odds ratio [OR]=4.351, p=0.005 and OR=4.236, p=0.001, respectively). CONCLUSION: The indications for surgical treatment can be defined as age >54 years and mass size >1 cm, even in IDP without atypia in the CNB results; this also includes cases of IDP with atypia or papillary neoplasm. Therefore, we suggest that close observation without surgery is sufficient for younger women with a small IDP without atypia.

Purpose:
This study aimed to report the projected cancer incidence and mortality for the year 2022 to estimate Korea’s current cancer burden.
Materials and Methods:
Cancer incidence data from 1999 to 2019 were obtained from the Korea National Cancer Incidence Database, and cancer mortality data from 1993 to 2020 were acquired from Statistics Korea. Cancer incidence and mortality were projected by fitting a linear regression model to observed age-specific cancer rates against their respective years and then by multiplying the projected age-specific rates by the anticipated age-specific population for 2022. A joinpoint regression model was used to determine the year in which the linear trend changed significantly; we only used the data of the latest trend.
Results:
In total, 274,488 new cancer cases and 81,277 cancer deaths are expected to occur in Korea in 2022. The most common cancer site is expected to be the thyroid, followed by the lung, colon and rectum, breast, and stomach. These five cancers are expected to represent half of the overall burden of cancer in Korea. The most common type of cancer leading to death is expected to be lung cancer, followed by liver, colorectal, pancreatic, and gallbladder cancers.
Conclusion
The incidence rates for all types of cancer in Korea are estimated to gradually decrease. These up-to-date estimates of the cancer burden in Korea could be an important resource for planning and evaluating cancer-control programs.

A clinical study was carried out on 206 glaucomatous patients(295 eyes) from July 1982 to December 1985 in the Department of Ophthalmology of Hanyang University Hospital. The results were as follows: 1. The glaucomatous patients consisted of 34.0% of primary open angle glaucoma(P.O.A.G.), 32.5% of secondary glaucoma, 20.9% of primary angle closure glaucoma(P.A.C.G.), 73% of ocular hypertension, 3.9% of congenital glaucoma and 1.5% of low tension glaucoma. 2. The mean intraocular pressure(IOP) of P.O.A.G. and acute stage of P.A.C.G. was 33.4 +/- 15.5 and 55.2 +/- 8.4mmHg, respectively. 3. 43.1 +/- 16.3 years was the mean age of P.O.A.G. and 61.6 +/- 9.5 years was that of P.A.C.G. 4. In overall glaucomatous patients there was no remarkable sex-difference except P.A.C.G. which showed higher prepondrence of females. 5. There was no significant difference in laterality between left and right eyes with glaucoma or ocular hypertension.

BACKGROUND: Renal dysplasia is the abnormal development of the kidney. The condition is usually detected in childhood along with other urinary tract anomalies, but can remain unnoticed until adulthood. It was recently reported that a PAX2 gene mutation plays a major role in the development of renal dysplasia. The aim of this study was to examine the expression of PAX2 in dysplastic kidneys of children and adults. METHODS: A total of 30 cases diagnosed with renal dysplasia after a nephrectomy were examined. PAX2 expression was evaluated using immunohistochemistry. Apoptosis was detected using an Apop Tag detection kit. RESULTS: In the dysplastic kidneys, there was strong PAX2 expression in the epithelia of the primitive ducts in both children and adults, but the degree was significantly lower in adults (p=0.007). However, the mesenchyme surrounding the primitive ducts of children showed stronger staining for the smooth muscle actin antibody and trichrome than the adults. The apoptosis index was significantly higher in the primitive duct epithelia than in the surrounding normal collecting duct epithelia (p=0.000). CONCLUSIONS: PAX2 is overexpressed in the primitive ducts of renal dysplasia, which is sustained until adulthood and is associated with increased apoptosis. However, a decrease in PAX2 expression in the dysplastic epithelia and mesenchymal cuff of adults suggest a gradual regression of the dysplastic elements with time.

From 1986 to 1995, 75 eyes of 75 patients who were admitted with a diagnosis of infectious corneal ulcer at Chunbuk university hospital were analyzed on the etiologic agents and clinical findings. Etiologic agents of infectious corneal ulcer were classified as 49 bacterial ulcers(65.3%) and 26 fungal ulcers(34.7%). The most common isolated bacteria was 8 cases of coagulase negative staphylococcus and pseudomonas species was the most common isolated gram negative organism. Candida species was the most commonly isolated fungus. Hypopyon was noted in 30 cases(40%) of infectious corneal ulcers, 14 cases in small ulcer group and 16 cases in large ulcer group. There was no difference between severity and presence of hypopyon of the 75cases (P>0.05. chi-square test).

PURPOSE: To evaluate the MR image in the differentiation of benign and malignant lesion in compression of the vertebral body. MATERIALS AND METHODS: MR images of 47 benign(acute traumatic within one month:19, chronic traumatic longer than one month or nontraumatic:28) and 21 metastatic compression fractures were respectively reviewed in terms of margin of lesions, signal intensity, paraspinal mass formation, soft tissue change, and involvement of posterior element of vertebra. MR images of TI-(T1WI) and T2*-weighted gradient echo (GE T2WI) sequences were obtained on 0.5T unit in sagittal and axial orientation with 5mm section thickness. RESULTS: The margin of benign compression fracture was usually indistinct (acute fracture:90% (17/19), chronic fracture:68% (19/28)), whereas it was sharply delineated in metastatic compression fracture (92%, (12/13) (p<0.001). Paraspinal mass was seen in both acute traumatic and metastatic compression fractures (acute fracture :26% (5/19), metastatic fracture: 52% (11/21). Soft tissue change was seen only in acute cornpression fractures (58%, 11/19). Involvement of posterior element of vertebra was noted in metastatic fracture (71%, 15/21), acute fracture (32%, 6/19) and chronic fracture (7%, 2/28) CONCLUSION: On MR imaging, involvement of entire portion of a given vertebral body, sharp margin between normal and abnormal areas in partially involved cases, paraspinal mass formation, and posterior element involvement are more frequently seen in metastatic compression fractures, which are considered to be useful in differentiation between benign and malignant causes of compression fracture.
