Bone marrow pressure is neither arterial pressure nor venous pressure of extremity, that is thought the precapillary pressure of bone. It is different between long bone and flat bone, and is also different in various site of the bone. Author measured bone marrow pressure of 84 normal femoral heads of Korean adults for basic data of early diagnosis of avascular necrosis of femoral head. The results are followings : 1. The baseline bone marrow pressure of Korean healthy adults is average 22.5 ±7.2mmHg. 2. The most significant change of bone marrow pressure in stress test is observed at 5 min. after injection of 5cc normal saline. 3. The increase of bone marrow pressure at 5 min. after stress test was average 7.4 ±4.4 mmHg. 4. Sex and age factors do not influence bone marrow pressure.

Fifteen cases of genital warts were examined for the presence of human papillomavirus (HPV) using polymerise chain reaction (PCR). HPV6/11 DNA were found in all cases of genital warts. The PCR based methods described here provide a sensitive, accurate means of detecting genital HPVs.

We performed analysis of 79 childhood patients diagnosed as vitiligo and nevus depigmentosus in Tediatric Dermatologie Department of Seoul National University Hospital from March 1987 to September 1987. The results were as follows : 1. Of the 79 patients, 31 patients(39.2%) were vitiligo 21 patients(26.6% )were nevus depigmentosus and 27 patients(34.2%)were uncertain by cliniral diagnostic ctriteri.. 2. Viiligo began rarely in infancy(6.4% )and most appeared evenly in all childhood over 1 year old. Nevus clepigmentosus was present at birth in 57.1% of patients and was discovered within the first 6 months after birth in 42.9% of patients. 3. In vitiligo, most lesions were multiple. The most common site of involvement was the face, and there was this tendency of periorficial predisposition. In nevus ciepigmentosus, most lesions were solitary. The most, common aites of involvement were the lowed limbs and trunk, but there was no tendency of periorfcial presposition. 4. We found focal type of vitiligo in,51,6% of patients, vulgaris type in 32. 3 % acrofacial type in 9.6% and segmerital type in 6.5%. We also found isolated pattern of nevus clepigrnento us in 76.2% of patients, ciermatomal p<:ttern in 19.0ki and whorlec1 pattern in 4.8% The contrast enhiancement between the hypopigmented skin and nomal surrounding skin by Wood's light, examinatior reflected the epiclermal melanin pig merit, i. e., the more marked loss of pigmentation, the more accentuatian of the contrast The before, Wood's light examination without I:3OPA staining could help to ciiagnose the atisculte type of vitiligo showing eidermal melanocytes and nevu c.Iepigmeritosus.

Febrile ulceronecrotic PLEVA is an unusually severe from of PLEVA, characterized by the sudden onset of diffuse ulceronecrotic eruption aasociated with high fever. A mild eruption precede the acute fulminating course, We observed a 13-year-old boy presenting the form of febrile ulceronecrotic PLEVA. The histologic features were those of PLEVA. He received the systemic corticosteroids with aupportive care. To recognize this disorder is important because of a possibly fatal outcome, So close attention and vigorous therapy are necessary.

Buoy flap was useful method for soft tissue defect, bone defect or bone and soft tissue defect. Also the buoy flap could use monitoring for blood flow. The advantages of the buoy flap were long length of perforating cutaneous branch, large diameter of Peroneal vessel, transposition in same leg and the another advantage was that the fibula is the long, straight and mainly cortical bone. To obtain successful result of buoy flap, one must have the anatomic concept for vascular pattern (straight branch, proximal oblique branch, branch from muscular branch, distal oblique branch), relationships with surrounding muscles (between Peroneus m. and Soleus m., Through Peroneus m., through Soleus m.) and length of perforating branch. So, we studied total 19 person, 22 cases of buoy flap, who were admitted and took the operation at Kyung Hee University College hospital, from October 1985 to March 1987.

"Tumor-to-tumor" metastasis is a rare event; meningioma has been reported as the most common primary intracranial tumor to harbor cancer metastases. Several hypotheses have been previously proposed to explain this occurrence, but the exact mechanism by which these metastases develop into meningiomas is not yet understood. Magnetic resonance imaging and spectroscopy have been valuable diagnostic tools, but preoperative diagnosis of metastasis to meningioma remains highly difficult. We present a case report of a metastasis of non-small cell lung cancer into an intracranial meningioma.

BACKGROUND/AIMS: Not only scintigraphic measurement of gastric emptying(GE) is not standarized, but also several discrepancies exist in the influence of technical factors including instrument and methods of analysis on gastric emptying studies. The aim of this study was to determine whether investigating instruments, methods of analysis, affect gastric emptying rates of a radiolabeled meal in scintigraphic measurement. METHODS: Using two different scanners (single-headed gammma camera and double headed gammma camera), gastric emptying studies of radiolabeled meal (consisting of 1 g of resin) labeled with 2mCi of 99mTc-DTPA (50g of egg, 150ml of milk, 100g of rice; 611Kcal) were done in 16 healthy volunteers (16 men, age 27.5+/-3yrs). Anterior and posterior image were obtained from the supine position with two scanners at every timing interval. Anterior image only was analyzed to determine whether the differences in instruments affect gastric emptying rates. Sum of anterior and posterior counts obtained by double-headed gamma camera were compared to geometric mean. RESULTS: There were significant difference in gastric emptying rates obtained with anterior image between a single-headed scanner and a dual-headed scanner (P < 0.05, T1/2= 105.8+/-16.3 min vs 80.9+/-14.7 min). Sum of anterior and posterior counts was correlated well with geometric mean (r=0.93). Also observed difference between intraobserver and interobserver variation. CONCLUSIONS: These results indicate that instrumental variations in gastric emptying studies should be considered in interpreting individual study results. The simple sum of anterior and posterior counts could be an useful parameter in the analysis and interpretation of gastric emptying data.

The effects of different grades of running on esophageal motility and gastroesophageal reflux in the fed state were evaluated. We studied healthy volunteers (male: 12, age: 27+/-5 yr) using ambulatory esophageal manometry, pH catheter and portable digital data recorder. Each exercise was performed 30 min after meal, with 20 min of rest between exercises. Subjects exercised on a treadmill at 40% and 70% maximal heart rate. The number of gastroesophageal reflux episodes, the duration of esophageal acid exposure and percent time pH below 4 were significantly (p<0.01) increased during exercise at 70% maximal heart rate. The frequency of contraction (contraction/min) (p<0.05), frequency of repetition (p<0.01), percent of simultaneous contraction (p<0.01), percent of above 100 mmHg amplitude (p<0.05), and frequency of 2-peak contraction (p<0.01) were significantly increased during exercise at 70% maximal heart rate. However, median amplitude and median duration showed no significant changes between each exercise session. Postprandial running exercises induce gastroesophageal reflux, which correlates with exercise intensity. These effects are mediated by disorganized esophageal motility.
