We described a giant chroioangioma of the placenta that caused premature rupture of membranes at 31 weeks of gestation in a 31-year-old primiparous woman and a subsequent neonatal death of the baby. The placental mass, weighing 820 gm and measuring 21.5x15x4.5 cm, was easily shelled out from a edematous 1280 gm-placenta. The mass had a thin fibrous capsule and a solid fibromatous appearance. The infant, weighed 2175 gm, appeared edematous oon the whole body and had Apgar scores of 4 and 5 at 1 and 5 minutes respectively. The baby expired 4 days after birth due to high output cardiac failure and respiratory failure. Postmortem examination revealed markedly dilatated umbilical vein, inferior vena cava and right atrium with patent froamen ovale, congestive hepatosplenomegaly, pulmonary hemorrhages, and meconium aspiration pneumonia. Microscopically, the mass revealed a variety of histologic patterns, reflecting entire spectrums of villous vasculogenesis from loose myxomatous connective tissue and undifferentiated hemangioblastic cell nests to well-developed capillaries with hematopoietic cells in the lumen.

Progressive zosteriform macular pigmented lesion(PZMPL) is a chronic pigmentary dermatosis similar to progressive cribriform and zosteriform hyperpigmentation(PCZH). This dermatosis described by Simoes in 1980 is characterized by a uniformly tanned macular pigmented lesion in a zosteriform distribution preceded by multiple pruritic macular pigmentation in a part of the dermatome for a period. PZMPL is not a fully understood disease entity but it is thought to be a variant of PCZH. It is differentiated from PCZH by accompanying pruritus as a prodromal symptom, a characteristic clinical course, and histological findings such as pigmentary incontinence. We report herein a case of PZMPL in a 17 year-old girl with the pigmentary skin lesion extending from the left forearm to the left chest along the Blaschkos line. The histological findings revealed increased melanin pigments in the basal layer and focal pigmentary incontinence in the upper dermis. To our knowledge, this case is the first report of PZMPL in korea thought to be the same case reported by Simoes.

PURPOSE: To investigate which spectral domain optical coherence tomography (SD-OCT) findings predict visual outcome after anti-vascular endothelial growth factor (VEGF) treatment in neovascular age-related macular degeneration (NV-AMD). METHODS: We reviewed the medical records of patients with treatment-naive NV-AMD who underwent three or more consecutive anti-VEGF injections. The patients were divided into three groups according to their changes of visual acuity (VA); improved (group I), static (group S), or worsened (group W). We assessed the incidences and values of all available SD-OCT findings of these groups, compared these findings between the three groups and compared the initial values with the post-treatment values. RESULTS: Better initial VA and longer external limiting membrane (ELM) length were associated with less change in VA after anti-VEGF treatment. The initial VA was mildly correlated with initial photoreceptor inner and outer segment junction (IS/OS) length and initial ELM length. The final VA was also mildly correlated with the final IS/OS length and the final ELM length. VA was significantly changed after anti-VEGF treatment in groups W and I. With regard to incidence, disruption of the IS/OS (IS/OS-D), disruption of the ELM (ELM-D) and ELM length differed significantly between the three groups, particularly ELM-D. The incidences of IS/OS-D and ELM-D in group I were significantly lower than those in groups S and W, and those in group S were also lower than those in group W. The ELM length in group I was significantly longer than it was in groups S and W, and the ELM length in group S was longer than that for group W. However, these three findings did not change after the anti-VEGF treatment. CONCLUSIONS: Initial IS/OS-D, ELM length and particularly ELM-D can be useful predictors of the visual outcome after anti-VEGF treatment in NV-AMD patients.

BACKGROUND: Pravastatin, HMG-CoA reductase inhibitor, has been known to be the most effective drug in patients with hypercholesterolemia. We studied the effectiveness and side effects of this drug. METHODS: We studied twenty four patients(8 males, 16 females), with pravastatin 5mg bid for 8 weeks, whose fasting serum total cholesterol levels were higher than 240mg/dl on the first visit. Lipid profiles were checked at 2 weeks interval for 8 weeks and compared with baseline level individually. RESULTS: Among lipid profiles, pravastatin significantly decreased the total cholesterol from 282.8mg/dL to 224.5mg/dL(reduction rate, 21%), the LDL cholesterol from 197.2mg/dL to 143.8mg/dL(27%), the total cholesterol/HDL cholesterol ratio from 6.2 to 4.6(25%), and the LDL cholesterol/HDL cholesterol ratio from 4.1 to 2.7 (34%). These changes were statistically significant(p<0.05). Triglyceride and HDL cholesterol showed no significant changes compared to baseline levels during treatment. The clinical and laboratory findings after treatment did not show serious abnormalities except two patients who dropped out due to side effect such as constipation and skin eruption. CONCLUSION: Results from the present study show that short-term pravastatin therapy seems to be effective and safe in patients with hypercholesterolemia.

Each three rabbit corneas were stored in McCarey-Kaufman medium at 4 degrees C for 5, 9 and 14 days and used as donor materials in 6mm partial penetrating corneal allografts. These results were compared to that group of penetrating keratoplasties with corneas stored conventional moist chamber at 4 degrees C for 5 days. All the M-K media stored corneas for 5 and 9 days were in clear graft after keratoplasty during the observation period of 6 months but the corneas stored for 14 days were developed eventvally irreversilde opaque after grafts. At 6 months after keratoplasties allthe rabbits eyes were enucleated and sectioned for histopathologic study of endothelia with the light and electron microscopes. Endothelia of the corneas stored for 5 and 9 days showed rarely endothelial degenerative changes. But the corneas stored up to 14 days showed significant changes including of disappearanee of most endothelial membranes and cytoplasms in light microscopies and swelling of nucleus, dispersed chromatin clump, multiple small and large vacuoles in cytoplasm and occasional autolysis of cytoplasm were observed in electron microscopies.

PURPOSE: MRI is known to be an effective imaging modality of the aorta and its role is steadily increasing in the evaluation of acquired aortic diseases including aortic dissections and aortic aneurysms. However, differentiation of the aortic dissections with thrombosed false lumen from the aortic aneurysm with mural thrombus in MRI has not been easy. Therefore, the authors tried to find the characteristic MR featrses which would to differentiate the two diseases. MATERIALS AND METHODS: MR images of 6 patients with thrombosed aortic dissection and 7 patients with thrombosed aortic aneurysms were reviewed retrospectively and compared in regand to shape and extent of thrombus, dimension of aorta, and luminal flow signal. RESULTS: Thrombosed aortic dissections showed sharply demarcated crescent shaped aortic wall thickening of even thickness involving long segment of the aorta, whereas thrombosed aortic aneurysms showed irregular aortic wall thickening of uneven thickness localized in the short dilated segment of the aorta. Characteristically aortic aneurysm with mural thrombus showed eccentric intraluminal slow flow signal. In contrast to the signal void of the true lumen in aortic dissections, the residual lumen of the aortic aneurysm with mural thrombus revealed intraluminal signal due to slow flow. CONCLUSION: Familiarity to these MRI findings of thrombosed aortic dissections and aortic aneurysms may lead to the accurate differential diagnosis in majority of cases.

The success of Moore and Thompson endoprosthesis in arthroplasty of the hip during the past three decades has prompted their continued use with but few alterations. Recently, to reduce the intolerance of acetabular cartilage and bone to frictional shear forces, the conventional endoprosthesis was modified, so many types of bipolar arthroplasty were introduced and implanted. But, the movements of the two components and acetabular erosion are rather controversial still. Among the 51 cases of bipolar endoprosthesis those have been operated at department of orthopaedic surgery, National Medical Center from 1981 to 1986, we analysed 40 cases for acetabular erosion and 22 cases for motion study of two components under the fluoroscopy. Following results were obtained, 1. Among 40 cases, there was no true protrusio acetabuli and increased CE angle in 12 cases(30%), which were limited to cartilage. 2. Under the fluoroscopic study, we found motion at inner and outer bearing joint in 14 cases, inner bearing joint only in 6 cases and outer bearing only in 2 cases. 3. The CE angle was increased more in younger age group than older group. 4. According to indication of bipolar arthroplasty, CE angle was increased more in disease group than trauma group. 5. The CE angle was increased more in leg length discrepancy and head piece size discrepancy group than the other group. 6. The CE angle can be substituted for joint space measurement. 7. The CE angle was increased more in low Harris hip rating score group. 8. Harris hip rating score had no correlation to motion of two components.
