Six cases of a rare variant of endocervieal adenocarcinoma (Adenoma maligum, AM) were collected for clinicopethologic analysis. The everage age of six patients was 49.3 years, and their chief com plaints were persis(ent mucid or watery discharge and intermittent vaginal spotting, The clinical im presaion was carcioma of The uterine cervix in faur out, of six cases. All except one were pathologically confirmed by initia1 biupey. two cases by colposcopic biopsies, two by cone biopsies, one by cone biopsy after suggested AM in calposcopic hiopsy. One case was incidentally found from hysterectnmised speeimen, which waas suspected as adennmyosis. On gross examination, the cervix usualty appeared either firm or indurated with thickening af the wall excepl one which was presented es a fungnting mass. The characteristic histologic feetures were ext,ensive arborizing endeervical glands with marked variation in size and shape, and the glands lined by mucin conyaining columnar epithelial cells with basal bland looking nuclei but with occasional cytologic atypia and rare mitose. The nenplasi.ic glands were characterized by deep stronml invasion be yond normal enddcervical glands, assosiated with loose edematous periglandular desmaplastic stromal reaction in moat cases. Immunohistochemical stainnings for carcinoembryonie antigen (CEA) revealed ey- toplasmic positivity in five cases. The clinical stage for all exeept one incidental case were : four Ib and one II b. In three cases, the radical hysterectomy with unilateral salpingooophorectomy plus dissection of bilateral pelvic and paraaortic lymph nodes was performed, and in one case radiotherapy was done prior to radical hysterectomy with bilateral salpingoophorectomy plus the dissection of left pelvic lymph nodes followed by chemotherapy. Total abdominal hysterectomy with bilateral salpingooophorectomy plus Burch's operation followed by radiation therapy was performed in on case. The remaining one case was treated with radiation therapy. Metastasis to the left obturator lymph node was discovered in one case with state IIb, and the patient expired 29 months after the radiotherapy. The remaining five cases are being carefully followed up. From our experience, we conclude that the early diagnosis of AM can be made based on comprehensive analysis concerning the clinical features, histopathological and immunohistochemical findings. The early diagnosis and proper therapy can lead to the better prognosis.

To evaluate the possibility of the newly developed highly porous glass ceramics as a space-filler in the cavitary bone defect, we made the opening sized 1 × 0.5 cm on the medial aspect of the right proximal tibia of nine rabbits. We impacted the highly porous glass ceramics firmly to the medullary cavity of rabbit tibia through the opening. Each three were sacrificed at 4th, 8th, and 12th week and analyze in vivo reaction of the glass ceramics in rabbit tibia with radiological and histological methods. On radiological examination, radiolucent line was seen around impacted glass ceramics at 4th week, but this radiolucent line was obliterated gradually to 12th week. On histological examination, new bone formation with osteoblast was appeared at 4th week without foreign body reactions. At 8th week, newly formed bone infiltrated into the porous space between glass ceramics particles was noticed, and the surface of glass ceramics was tightly bound by newly formed bone with osteoblastic rim and mature bone, At 12th week, the amount of newly formed mature bone increased, though there was on evidence of resorption of glass ceramics particle. So, we suggest that the highly porous glass ceramics is one of the possible artificial bone graft substitutes, especially as a space-filler.

Ganglioneuroma is a rare benign tumor which originates in the neural crest, and is found along the path of the sympathetic chain, from the base of the skull to the pelvic cavity. Due to the slow growth of this type of tumor, it may be detected incidentally, or detected by virtue of the attendant pressure effects on adjacent structures. We report one case of ganglioneuroma arising in the pelvic cavity.

PURPOSE: To discover the characteristics and rates of myopic progression with increasing age in children who have had history of retinopathy of prematurity (ROP). METHODS: Retrospective chart review was performed of 72 eyes in 36 children who were diagnosed with ROP. Inclusion criteria were myopia over -0.5 diopter and the children that could have been followed for at least 5 years or longer. The subjects with stage 4 or 5 ROP were excluded. Data on the retinoscopic refractions at every 6 month in each patient were recorded. We measured the annual rates of myopic progression in each subgroup which were divided according to the severity of ROP, treatment modality, and the different age intervals. RESULTS: Overall annual rates of myopic progression was -0.53 D/year. The severity of ROP was not correlated with the degree of myopia and the rates of myopic progression. In terms of the rates of myopic progression, statistical significance was found only in subgroups who were treated by cryotherapy. The myopia in age group over 5 years showed less progression than that in age group under 5 years. In the patients with anisometropia, there was a tendency that the discrepancy in the refractions of both eyes decreased gradually with increasing age although there was no statistical significance. CONCLUSIONS: The rate of myopic progression was not directly correlated with the severity of ROP. But the myopia in patients who had undergone cryotherapy showed a marked progression with significantly higher rate.

OBJECTIVE: Abnormal uterine bleeding is the most common disorder of gynecologic department. Organic causes of abnormal uterine bleednig are chronic cervicitis, submucosal myoma, endometrial polyp, endometrial malignancy. To find the exact cause of uterine bleeding, hysteroscopic endometrial biopsy was used. METHODS: 214 patients were included in the study, who received hysteroscopic endometrial biopsy from Feb. 2000 to Dec. 2002 with abnormal uterine bleeding, negative in urine pregnancy test, normal in cervix cytology, and without organic lesion causing uterine bleeding in pelvic examination and ultrasonography. Age, parity, hysteroscopic biopsy result were analyzed retrospectively. RESULTS: Mean age of study group was 42 and mean parity was 2.75. When final hysteroscopic biopsy histology were analysed, proliferative phase was most common (28.9%). Next followed secretory phase (18.2%), simple hyperplasia (13.5%), endometrial polyp (9.8%), chronic endocervicitis (5.1%). Submucosal myoma (4.2%), endometrial cancer (4.2%). Complex hyperplasia were detected in 3.2%. Of 214 patients, who complained uterine bleeding, only 99 (47.1%) patients were proved true non- organic uterine bleeding on hysteroscopic biopsy. Remainder had organic disorder (39.8%). CONCLUSION: When a patient visits the hospital with abnormal uterine bleeding, doctor should be suspicious of endometrial organic disease and treat the patient under exact diagnosis. In these patients, hysteroscopic examination and biopsy were very useful and safe method to determine exact diagnosis and treatment plan.

Two patients with spontaneous intraretinal or subretinal hemorrhages were found, on evaluation by fluorescein angiography, to have macroaneurysms involving the major retinal arteries. Both patients were male in their seventies. One patient had a history of systemic hypertension. In the other patient, hypertension was discovered at the time of consultation. With absorption of the hemorrhage and the macular star, two patients experienced appreciable improvement in vision. Laser thrapy was not applied to both patients. The aneurysms diminished in size after 6 to 8 months as a result of fibrous changes within the arterial walls.

PURPOSE: Febrile seizure affects 2 to 5% of children, but 30 to 40% of the children who already had febrile seizure experience another febrile seizure. We researched to define a high risk group of recurrent febrile seizures through investigating several risk factors. METHODS: We evaluated 342 patients who were admitted to our hospital or treated in the emergency room for their first febrile seizure from March, 1995 to August, 2001. We assessed various risk factors, such as age, the type of seizure, body temperature, serum sodium concentration, sex, neurologic abnormalities, and family history of febrile seizure or epilepsy. RESULTS: Age at the first febrile seizure(< or =18 months) and family history of febrile seizure were significant risk factors for recurrence of febrile seizure. The study showed that 21.9% of the children who had none of these risk factors, 36.4% of the children who had one, and 57.1% of the children who had both factors had recurrent febrile seizures. Thus, the recurrence rates clearly increase as the number of these factors increase. CONCLUSION: Two major risk factors for recurrent febrile seizures were identified:early onset(< or =18 months) and family history of febrile seizure. The risk of recurrent febrile seizures increased with the number of these risk factors increased. Consequently, children with both risk factors were considered to belong to a high risk group of recurrent febrile seizures.

PURPOSE: To investigate transitional changes in refractive error distributions in a pediatric population using the Korean National Health and Nutrition Examination Survey (KNHANES) data. METHODS: We investigated 7,181 subjects from the 4th and 5th (2008–2012) KNHANES and 1,225 subjects from the 7th (2016) KNHANES; all subjects were 5 to 18 years of age. We used the average spherical equivalent (SE) of both eyes calculated with noncycloplegic refractive errors measured via autorefractor. We determined SE percentiles by age in order from hyperopia to myopia. We acquired the mean SE by age. We investigated the proportions of subjects with mild, moderate, and severe refractive errors by age. RESULTS: Mean refractive errors were −1.73 ± 2.16 diopters in subjects in the 4th and 5th KNHANES and −1.66 ± 2.21 diopters in subjects in the 7th KNHANES; these were not significantly different between the two groups (p = 0.071). Mean refractive errors were more myopic in subjects in the 4th and 5th than in subjects in the 7th KNHANES only at 8 and 9 years of age (p = 0.018, p = 0.026). The distribution of percentiles by age was similar between the two groups. The respective proportions of hyperopia, emmetropia, and myopia were 6.2%, 27.6%, and 66.2% in subjects in the 4th and 5th survey, and 7.3%, 29.7% and 63.0% in subjects in the 7th survey. There was no significant difference in refractive error proportion between the 2 groups (p = 0.326). CONCLUSIONS There was no definite transitional change of refractive error distributions between the two KNHANES groups. However, additional periodic surveys are needed to confirm this hypothesis.

Inverted papilloma is a rare urothelial neoplasm most frequently occurred in the trigonal region of the urinary bladder. But, it rarely arises in the renal pelvis. The characteristic downward proliferation of urothelial cells within the underlying lamina propria is of such magnitude as to result in an exophytic papillomatous tumor. It was regarded as a benign neoplasm, but the malignant tendency is now being reported with inverted papillomas of urinary tract, and therefore they are no longer regarded as innocuous benign neoplasms. We report a very rare case of inverted papilloma of the renal pelvis and review the relevant literatures.
