BACKGROUND: It has been well known that absolute and interpeak latencies of brainstem auditory evoked potentials (BAEP) are usually prolonged in diabetics. However, Its etiology is still controversial. We tried to identify whether the cause is structural or metabolic in origin by performing BAEP and brain MRI in the diabetic patients. METHODS: BAEP were performed in both the diabetic patients (DM) group (16 males and 15 females) and the normal control group (25 males and 33 female). A brain MRI was performed in the DM group on those who showed abnormal BAEP and com-pared the results of BAEP of the DM group with those of the control group. RESULTS: 7 patients (22.6%) showed abnor-mal BAEP (male; 6, female; 1, unilateral; 4, bilateral; 3) when abnormal BAEP was defined as being larger than two and a half standard deviations of the control group BAEP results. Two males of the DM group who showed abnormal structural lesions of the pons in their brain MRI were not included in the statistical analysis. The remaining 14 diabetic male patients (mean age: 58.7 +/-9.1 years, mean disease duration: 6.1 +/-4.7 years, mean hemoglobin (Hb) A1C: 7.7 +/- 2.0%) and 15 diabetic female patients (mean age: 60.6 +/-10.8 years, mean disease duration: 5.4 +/-5.1 years, mean HgA1C: 7.8 +/-2.1%) were stastistically analyzed. Interpeak latencies of I-III, III-V, and I-V were found to be signifi-cantly prolonged in the DM group. The prolongation of interpeak latencies of I-III and I-V were found to be signifi-cantly correlated with the disease duration only in the diabetic female patients, but not with age and HbA1c. CONCLUSIONS: These findings suggest that both metabolic derangement and structural lesion contribute to prolonging the central conduction time on BAEP pathway in diabetics.

It is difficult to treat the complete cleft lip because of wide cleft and malaligned alveolar process, outward rotation of greater(medial) alveolar segment, and severe nasal deformity. Lip adhesion without presurgical orthopedic appliance was performed on 8 consecutive infants with unilateral complete cleft of the primary palate before denfinitive lip repair with Millard I procedure. Among 8 patients, 6 patients had complete unilateral cleft lip with alveolar cleft only and 2 patients were accompanied with complete cleft palate. All patients had more than a 10-mm-wide lip cleft with alveolar arch discrepancy. Lip adhesions were performed at 1-2 months of age and definitive repair was done at 5-6 months of age. Lip adhesions were performed by Randall's method and cheiloplasty was done by Millard I technique. Satisfactory results of lip and nose were obtained aesthetically in 8 cases after an average follow-up of 32 months. The vertical height of the medial and lateral lip segment were a symmetric appearance, while the vermilion tubercle, philtrum, and Cupid's bow were natural. Disadvantages included increased operating time and the sacrifice of same-lip tissue. In conclusion, preliminary lip adhesion can have better functional, esthetic and emotional results since the disadvantages are minor compared to the advantages.

Hospitals are increasingly concerned with the construction of computer-based medical order communication system (MOCS), despite the fact that they are financially being pressed. With limited budget, management in hospitals ought to be pursuing both methodologically effective and technically sound way of constructing MOCS. This paper intends to contribute itself toward better design of database for MOCS with reference to a university hospital. Some structural characteristics pertaining to MOCS are identified in ways of systems approach. Based on those findings, construction methodologies are reviewed and put forward with flexibility to differing requirements of hospitals. Suggestions include the followings. (1) Designing step has to be distinguished among conceptual, logical, and physical design while prototyping for user interface is utilized only for the logical design. (2) Many modeling tools including entity life cycle diagram can be effective for system integration with other units. (3) 3 different types of distributed database servers are recommended.

The author analyzed 352 patients who had been admitted to P.M.C. with clinical signs and symptoms of occlussive stoke from 1973 to 1980. Cerebral angiography was performed on 250 patients and 126 patients of them were confirmed to have angiographical evidence of occlusion. We've analyzed these 126 patients in clinical point of view. As presented above, positive rate of angiography was 50%. The site of lesion was most common at MCA which was somewhat different from other reports, and the side of predelection was left. In majority of cases, the occlusive stroke was occurred in age group between 40 to 60, and man was about 3 times as common as woman. Risk factors, in our series, were hypertension, cardiac problems, diabetes and so on which were similar to other reports. Hypertension, the most common risk factor, correlated well to the peak age incidence but there was not any intimate relationship with the level of serum cholesterol. The outcome of medically treated group(112 patients) was somewhat better than surgery(14 patients). Among 12 of EIAB, TIA noted the best result compared to RIND and SIE. Meticulous selection of patient using CT scanning and measurement of rCBF would promote the benefit of surgery.

From May 1988 to January 1997 authors had experienced 13 cases of recurred blepharoptosis. Previous operative procedures were frontalis muscle suspension in 10 cases and levator resection in 3 cases. Follow up period ranged from 11 months to 9 years. We have treated recurred blepharoptosis using frontalis myofascial flap, orbicularis oculi muscle flap and levator resection in accordance with the postoperative levator function and degree of ptosis of patient and considering previous operative technique. The results were that 12 patients have gained the levator excursion over 7 mm and reduced the height difference between both palpebral fissures less than 2 mm after reoperation (good in 6 cases and satisfactory in 6 cases). From these results we might conclude that the frontalis myofascial flap technique is a good secondary blepharoptosis operation for patient with less than 2 mm of levator function, orbicularis oculimuscle flap technique with 2-4 mm of levator function, levator resection with over than 4 mm of levator function. The expert technique and experience are also important factor for the treatment of recurred blepharoptosis.

The extensive knowledge of accurate anatomical morphology and acceptable proportion of the eyelid and orbit should be needed for plastic surgeons. The normal morphological and functional values of eyelids and orbits are variable according to races, sex and ages, and there are a few articles concerning them in Korea yet. The author measured eigt items of morphological and functional values of eyelids in Koreans and statistically analyzed them in 498 individuals including 234 males and 264 females. We divided them into nine age-related groups and measured the values. Especially, we subdivided 10 to 19 year-old group into three subgroup concretely because most of the values in the 10 to 19 year-old group reach the peak level of growth. The mean values in adults were recorded as follows: The horizontal dimension of the palpebral fissure was 27.0 +/- 1.8 mm in males and 26.8 +/- 1,7 mm in females and the vertical dimension of the palpebral fissure was 8.0 +/- 1.0 mm in female. The slant of the palpebral fissure was 7.9 +/- 2.4 degrees in males and 8.8 +/- 2.3 degrees in females and the height of the opened upper eyelid was 12.4 +/- 2.4 mm in males and 12.0 +/- 1.9 mm in females. The height of double fold in closed eye was 6.6 mm in males and 6.5 mm in femals and the intercanthal distance was 38.4 +/- 3.0 mm in males and 38.2 +/- 2.8 mm in females. The interpupillary distance was 64.6 +/- 2.9 mm in males and 63.6 +/- 2.9 mm in females. A double fold was seen in 36.1% of Korean. The average height of the double fold in closed eye was about 6.5 mm. The epicanthus present in 58.6% of Korean eyes and the most commom type was epicantus tarsalis. The growth of eyelids reached the peak level at teenager in a great portion. After the peak level, the changing pattern of eyelids could be divided into 3 groups; the first one was increasing more, the second was stationary, and the third was decreasing gradually. The peak levle of growth reached at 10 to 13-year-old in the vertical dimension of the palpebral fissure, at 14 to 16-year-old in the intercanthal distance, at 17 to 19-year-old in the horizontal dimension of the palpebral fissure.
