Subretinal neovascular membrane in the macula is a major cause of central visual loss. We reviewed the clinical records, fundus photography, fluorescein angiography of the 172 eyes of 166 patients in order to disclose the causes and clinical characteristics of subretinal neovascular membrane and performed argon and krypton photocoagulation in 22 patients. The common causes of subretinal neovascular membrane are idiopathic neovascular membrane, myopic and senile macular degeneration in order(27.1, 26.5, 22.3% aa). There was no significant difference in changes of visual acuity and extent of subretinal neovascular membrane between treatment and non-treatment groups.

Accurate preoperative CT staging of renal tumor affects the therapeutic approach and aids the urologist in planning the appropriate procedure. CT staging were compared in 33 patients with pathologically confirmed stage of renal tumor. The overall accuracy of CT staging in renal cell carcinoma is 87.0%. The overall accuracy of CT staging in renal pelvis tumor is 80.0%. The major role of CT was in the evaluation of renal capsule, perirenal fat, Gerota's fascia, renal vein, inferior vena cava and lymph node for invasion. We conclude that at the present time CT is the optimal technique to stage renal tumor.

Two cases of association of brain tumor and intracranial aneurysms are reported. One case is association of pituitary adenoma with anterior communicating artery aneurysm. The other is association of acoustic neurinoma with multiple aneurysms and it is exceedingly rare reviewing the available literature. Various pathogenesis for association of brain tumor with cerebral aneurysm have been postulated.

PURPOSE: To evaluate the results and efficacy of the subtalar distraction arthrodesis on patients with complications due to malunion after intra-articular calcaneal fracture. MATERIALS AND METHODS: From October 2001 to September 2004, we operated on 10 patients (14 cases). There were 9 male patients and one female; their mean age was 41 years old. Ten cases among them were operated initially. The mean period between initial injury and arthrodesis was 18 months. The mean follow up period was 16 months. During the operation, we used extensile lateral approach and arthrodesis was performed using tricortical bone block and cannulated screws. The ankle-hindfoot scale was used for clinical evaluation. In radiologic analysis, plain X-ray and CT of the both feet were examined for union and various parameters. RESULTS: Thriteen cases achieved radiologic bone union. The mean ankle-hindfoot scale (maximum: 94 points) increased from 52.4 points preoperatively to points 77.2 at the final follow-up. The radiologic analysis of the pre and postoperative standing lateral radiograph showed mean increase of 6.9 mm in talo-calcaneal height, 5.2 degrees in talocalcaneal angle, 4.3 degrees in talar declination angle and average decrease of 4.5 degrees in talo-first metatarsal angle. CONCLUSION: The short term result of the subtalar distraction arthrodesis using tricortical bone block was promising, but longer follow-up will be needed.

A case of sudden paraplegia as the first symptom of a ruptured internal carotid artery bifurcation aneurysm is reported. Sudden appearance of paraparesis or paraplegia is an exceptional event in patients with intracranial aneurysms. The various pathogenic mechanisms are briefly discussed. Insufficient blood perfusion of both paracentral areas was the cause of paraplegia in this case.

Software modules for interactive display, manipulation and retrieval of medical images have been designed for a Picture Archiving and Communications System (PACS). The target of these modules is not for a high-end diagnostic workstation for radiologists, but for a PC-based low cost clinical workstation for a referring physician. This software is constructed based on a concept of an object-oriented language which is designed to be modular and expandable. It consists of several functional modules: (a) a communication module for image retrieval, (b) a standard module for the interpretation of the DICOM images, (c) a user interface module for the non-computer oriented clinicians and (d) a tool module for viewing and manipulating images as well as editing the annotation.

OBJECTIVE: The aim of this study is to assess the correlation of progesterone challenge test (PCT) and endometrial thickness as a primary screening test for endometrial pathology in postmenopausal women prior to hormonal replacement therapy (HRT). METHODS: 92 postmenopausal women were measured serum estradiol (E2) level, endometrial thickness by transvaginal ultrasonography, and followed by PCT before HRT. And we compared the results of PCT with endometrial thickness and E2 levels. RESULTS: Women with a positive result of PCT in 32% of case and 75.9% of positive test showed endometrial thickness 4 mm or more. However 60.3% of negative test showed endometrial thickness 4 mm or more. This resulted in a PPV=76%, NPV=40%, sensitivity=37%, and specificity=78%. Mean serum E2 was significantly higher in patient with positive PCT but serum E2 showed no positive correlation with endometrial thichness (CI 95%, P Biopsy ; Estradiol ; Female ; Humans ; Mass Screening ; Menopause ; Pathology ; Progesterone* ; Ultrasonography

Numerous devices and technics have been devised to facillitate the difficult endotracheal intubation. We have modified the technic of employing a guide inserted retrograde through cannulation of the cricothyroid membrane. We easily used 16G ANGIOCATH for cannulation of the cricothyroid membrane and Angiography guide wire or swan Ganz Introducer wire for retrograde endotracheal intubation.
