PURPOSE: The purpose of this paper is to discuss the characteristic CT and MR findings in persistent hyperplastic primary vitreous(PHPV) and to compare the detectability of those findings in each modality. MATERIALS AND METHODS: We retrospectively evaluated CT and MR findings in 32 patients with PHPV. Twenty-five patients had CT, 13 patients had MR, and 6 patients had both CT and MR. RESULTS: Major findings of PHPV in 32 patients on both imaging modalities were lens deformity(78%), shallow anterior chamber(72%), heterogeneous vitreous opacity(72%), enhancing hyaloid artery or remnant of fibrotic hand(69%), and microophthalmos(67%). Minor findings were retinal detachment(22%), and vitreous hemorrhage(6%). In MRI, lens deformity(92%) and shallow anterior chamber(85%) were detected most commonly whereas in CT, opaque vitreous(80%) was the most common finding. Findings of enhancing hyaloid vessel or remnant of fibrotic band, considered characteristic of PHPV, were more commonly detectable in MR (85%) than CT(52%). CONCLUSION: Characteristic MR and CT findings of PHPV were lena deformity, shallow anterior chanber, heterogeneons vitreons opacity, enhanciny hgalind artery or remnant fibrotic band, and microphthalmos. MR seemed to be more useful than CT in detecting Globe pathology.

A 48-year-old woman, who had had tattoo on her eyebrows, was seen with pruitic erythematous indurated plaques on the tattooing sites. The skin react ion was begun to observe about 4 weeks after getting tattoo. Skin biopsy specimens from the indurated lesions showed granulomatous reactions. Intradermal tests by means of multiple pricks and patch test were done on her low back with the same tattoo dye and also 4 others available in Korea. Serial punch biopsy specimens were obtained from the sites of intradermal test at 2nd, 7th, 28th, and 56th day after intradermal test. Granulomatous reactions were found in the spiecimens taken at the 28th and 56th day.

Cryoglobulinernia occurs in about 5% of the cases of multiple myeloma. The most common finding in patient with cryoglobulinemia is ulceraticn that oceurs about ankle, hands, and occasionally the ears, upon prolonged exposue to cold. A 59-year old male had had 5 years of pain in his ears. There were black or dark brown colored ischemic ulcerations on his both helix. He also had mottled purpuric patches on his both ankles. A test for cryoglobulinema was positive. X-ray examination of the skull showed multiple punched but lesions. The bone marrow study revealed myeloma cell infiltration.

The effects of sodium hypochlorite for the destruction of P. aeruginosa, E. coli, K. pneumonias and S. anreas and for the prevention of contamination of irrigation fluid, which is either exposed to ICU environment or used for cleansing oral or trachea catheter tips, were tested and the following results were obtained. 1) The sodium hypochlorite solution 1: 800 destroyed P. aeraginosa, E. coli, K. pneomoniue and S. aweas in 5 minutes. This bactericidal effect was observed to be retained after the solution had stood 24 hours. 2) Viable P. aeraginosa was not detected immediately, 5 minutes and 10 minutes after exposure to 1: 500, 1: 800 and 1: 1000 sodium hypochloride solutions respectively. 3) The sodium hypochlorite solution 1: 800 prevented contamination of the irrigation fluids during a 24 hour exposure to the ICU environment. 4) P. aeraginosa and other gram-negative bacilli were frequently isolated from the plain fluid used for irrigating and holding the suction tips which had been used for patients. However, no organisms were isolated from fluid containing sodium hypochlorite 1: 800 even after 24 hour usage. It is concluded that the use of fluid containing sodium hypochlorite for the irrigation of catheter tips can reduce development of infections in the ICU patients.

Thirty consecutive anesthesia records of transurethral resection (TUR) have been reviewed. Patient's physical status, anesthetic management and complications were also discussed. Operations in this series were classified as follows: 25 cases of TUR for carcinoma of the prostate, 3 cases of bladder tumor. In all the thirty cases of TUR, circulatory diseases, such as hypertension were encountered most frequently. (10 cases) The patients had the highest mean age(66.5 years old) and their physical status was almost all ASA class II or III. Hypotension occurred in 1 patient during TURP. There was no death associated with anesthesia and operation in this study. Pain control after operation with epidural block was satisfactory in nearly all cases. Continuous epidural anesthesia for TUR and pain control after operation was desirable.

Arterial carbon dioxide partial pressure (PaCO2) and pH are basic indices of the adequacy of ventilation in anesthetized patients. Previous reports by us and by Frances et al indicate that peripheral venous Pco2 and pH approach values arterial blood during general anesthesia. The present study compares the arterial venous difference for Pco2 and pH during diethyl ether, methoxyflurane and halothane anesthesia in 20 cases each. After induction with thiopental, succinylcholine, the patient was intubated and maintained with N2O-O2 and one of above volatile agents. Venous blood was drawn from the back of the hand and an arterial sample was obtained from the radial artery of the other hand. The results were as follows: 1) The mean arteriovenous Pco2 differences in ether, methoxyflurane and halothane groups were -l. 25, -1. 425 and -0. 065 torr respectively. 2) The mean arterovenous pH differences in each group were 0. 031, 0, 017and 0. 014 respectively. We conclude from above results that the differences for the arteriovenous Pco2 and pH during halothane anesthesia were less than that of the ether or methoxyflurane groups.

Colloid oncotic pressure (COP) plays a major role in regulating fluid exchange at the capillary membrane, and the magnitude of COP is determined by the concentration of large plasma proteins in the colloidal state. COP is also a determinant in the morbidity and mortality of critically ill patients. To assess the role of COP in these patients, clinical data including COP, age, sex, PaO2, PaCO2, AaDO2, mean arterial pressure, length of stay in ICU, duration of mechanical ventilation and whether surgical or non-surgical treatment, were collected and analyzed from those who were admitted to the Intensive Care Unit of Severance Hospital from March to July, 1986, The resvlts are as follows : 1) The mean values of COP, PaO2, Pacoa and AaDO2 are 15.07+/-2.89, 108.46+/-51.59 and 36.14+/-7.27 and 123.89+/-127.27 mmHg. 2) COP was the highest contributing factor to a survival prognosis followed by AaDO2, age, PaCO2 and surgery. 3) The level of COP was correlated with survival rates, and for a 50% survival rate, the level of COP was 13.5 torr. The above results suggest that COP is a contributing factor to the survival of patients admitted to the Intensive Care Unit.
