Pulmonary aspergilloma may usually demonstrate the classic "air-crescent sign" in the conventional radiograph. However, this lesion is often seen as a pulmonary nodule or is obscured by the surrounding scarred and fibrotic lung tissue, which may limit the value of the conventional techniques and hinder the diagnosis. We retrospectively analysed the plan film findings of 44 lesions of 40 patients and CT findings of 29 lesions of 26 patients with pulmonary aspergilloma with special emphasis upon the atypical manifestation. The cases with classic "air-meniscus sign" in conventional radiograph accounted for 50%, while 30%, presented with a pulmonary nodule and 20% were unrecognized forms due to surrounding parenchymal lesion. CT findings of 28 aspergillomas were analyzed according to the shape of the intracavitary space(space between the cavity wall and the fungal ball) and the fungal ball itself. The intracavity space showed "air-meniscus sign" (62%), filling cavity (28%), peripheral air bubble (3%) and high density due to hemorrhage (3%), in descending order of frequency, The shape of the fungal ball itself showed homogeneous low density mass (62%) and spongeform or irregular air bubble contained mass (34%), CT was more accurate than conventional radiograph in the diagnosis and evaluation of number and location of atspergilloma, particularly in the case of atypical presentaion and was useful to assess the associated disease and to predict postoperative outcome.

BACKGROUND: The relationship between type II diabetes and congnitive function has been explored in several studies. But the result was controversial. The purpose of the study was to determine whether diabetes mellitus in older patients(>or=65 years) is assiciated with cognitive dysfunction and to discover the related factors with th cognitive dysfunction. METHOD: Twenty patients with type 2 diabetes and twenty subjects with non-diabetes are studied with cognitive function test at Hwachun health center and county hospital. Cognitive function was assessed using Mini-Mental State Examination and Clock Drawing test and the score was analyzed. The diabetes groups were subdivided with duration of diabetes, HbAlc, chronic diabetic complications and then analyzed. RESULTS: A total of 6(30%) diabetic subjects scored below 24 on mini-mental state examination, compared with 3(15%) of controls(p=0.2560). The mean socres were 20.1+/-2.7 and 19.0+/-3.5 respectively. Clock drawing test demonstrated that 13(65%) diabetic subjects inconectly placed the numbers and hands, compared with 7(35%) of controls(p=0.0578>0.05). The duration of diabetes mellitus, HbAlc, chronic diabetic com- plications were not associated with cognitive dysfun- ction among diabetic subjects. CONCLUSIONS: The study showed that type 2 diabetes mellitus in the elderly is not associated with cognitive dysfunction, but further study should be done.

Journal of the Korean Radiological Society 1993;29(4):730-737
Constrictive pericarditis is caused by fibrosis of the pericardium leading to decrease in ventricular compliance. The diagnosis is often delayed due to nonspecific signs and symptoms. The authors experienced eight cases of constrictive pericarditis detected on chest CT scan while being treated for considerable length of time under the clinical impressions of intrathoracic tumor, tuberculous pleural effusion, liver cirrhosis, etc. Constrictive hemodynamics of these patients were confirmed by echocardiogram and cardiac catheterization. Among them five cases were due to tuberculosis. In four cases with pathologically proven tuberculous granuloma, the pericardium was markedly thickened and intensely enhanced. Associated pericardial effusion (n=3), and mediastinal lymphadenitis (n=3) were present, but pericardial calcifications were not seen. On the other hand, the fibrosis group (n=3) displayed mild pericardial thickening. All the three patients showed pericardial calcifications, mild or absent enhancement of pericardium, but no mediastinal lymphadenitis. The cardiovascular changes such as inferior or superior vena caval distension, left ventricular deformity, interventricular septum angulation, and biatrial enlargements were more severe than those in patients with active granuloma. In patients with constrictive pericarditis with nonspecific signs and symptoms, CT scan is very helpful in making the diagnosis and can give informations about the evolution of the disease.

6.A Case of Congenital Lipoid Adrenal Hyperplasia.

Congenital lipoid adrenal hyperplasia is the most severe form of CAH, leading to impaired production of all steroid hormones including glucocorticoids, mineralocorticoid, and sex steroids. The affected individuals are all phenotypically female with a severe salt-losing syndrome that is fatal if steroid replacement is not begun immediately after birth. The lesion of this disorder has been suggested to be in the first step of steroidogenesis of conversion of cholesterol to pregnenolone by P450scc. Recently, molecular defect of this disease has been located in the transport of cholesterol into mitochondria due to defective regulatory protein called 'steroidogenic acute regulatory protein' while the enzyme P450scc itself is normal, differing from other types of congenital adrenal hyperplasia. We experienced 2 1/2 month old phenotypical girl who was admitted due to lethargic state and persistent vomiting with severe hyperkemia and hyponatremia. Blood levels of cortisol, aldosteron, and 17-OH progesteron were low and levels of ACTH, angiotensin, and plasma renin activity were high, urinary levels of 17-KS and 17-OHCH were low. The patient was found to have karyotype of 46, XY and has been being treated with predinisolone, fluorocortisol and sodium supplement in diet and doing well. The molecular study for P450scc gene and StAR gene of patient and family is in progress.

Journal of the Korean Ophthalmological Society 1999;40(9):2544-2555
This study was performed to determine whether peripapillary atrophy can be helpful in diagnosis of glaucoma and to investigate the correlation between peripapillary atrophy and optic disc head configuration in patients with primary open-angle glaucoma and normal-tension glaucoma. For all eyes, color polaroid optic disc photographs had been taken with Topcon retinal camera and reviewed. 93 eyes of normal subjects, 47 eyes of 47 patients with primary open-angle glaucoma and 47 eyes of 47 patients with normal-tension glaucoma were analyzed. Zone beta was detected more often in patients with normal-tension glaucoma and primary open-angle glaucoma (P<0.05). There was no significant difference in frequency of peripapillary atrophy between in patients with normal-tension glaucoma and primary open-angle glaucoma (P=0.071). In primary open-angle glaucoma,total,nasal and temporal neuroretinal rim area and total, inferior, nasal and temporal neuroretinal rim area/disc area ratio were smaller in patients with zone beta than without zone beta (P<0.05). The presence of zone beta was associated with neural tissue loss and progression of visual field in primary open-angle glaucoma (P<0.05). In conclusion,peripapillary atrophy, especially zone beta, is associated with glaucoma. Therefore, evaluation of peripapillary atrophy can be help-ful in diagnosing glaucoma. The presence of zone beta is associated with functional and structural optic nerve damage and is of predictive value in the future glaucomatous damage in primary open-angle glaucoma.
