Diagnostic ability of duplex Doppler ultrasonography reling on resistive index is limited when clinical symptoms and signs of rejection are subtle or renal dysfunction is caused by other conditions such as urinary tract infection. To investigate the significance in the changes of renal pelvis, a combined analysis of resistive index and ultrasonographic findings in cases of renal pelvis dilatation and mucosal thickening was undertaken. A mean resistive index was calculated from Doppler measurements of the main, segmental and interlobar arteries. The cause of mucosal thickening was retrospectively analysed using the clinical and laboratory findings. Twenty three cases of renal pelvis dilatation and 17 cases of mucosal thickening were found in a total of 159 renal transplantation cases. In 14 of the 23 cases with renal pelvis dilatation, renal function was normal and their mean resistive index was 0.64±0.04. Pelvis and ureter dilatation caused by ureteral stenosis or compression was demonstrated in 6 cases and their mean resistive index(0.72±0.05)was increased. Mucosal thickening of renal pelvis was found in 7 of 32 cases with acute rejection and in 2 of 13 cases with chronic rejection, but their mean resistive index was not different from that of the cases without pelvic mucosal changes Three cases of acute rejection associated with urinary tract infection and 2 cases of chronic rejection in whom resistive indices were indeterminate, but mucosal thickening of the renal pelvis was prominent at ultrasonography. In renal transplant patients having indeterminate resistive index and mucosal thickening of the renal pelvis, ultrasonographic features must be correlated with the clinical and laboratory findings for an accurate diagnosis and treatment of renal dysfunction.

The authors defined precaval retropancreatic space as the space between pancreatic head with portal vein and IVC analyzed the CT findings of this space to know the normal structures and size in this space, We evaluated 100 cases of normal anbdominal CT scan to find out normal anatomic structures of precaval retropancreatic space retrospectively. We also measured the distance between these structures and calculated the minimum, maximum and mean values. At the splenoportal confluence level, normal structures between portal vein and IVC were vessel (21%), lymph node (19%), and caudate lobe of liver (2%) in order of frequency. The maximum AP diameter of portocaval lymph node was 4mm. Common bile duct(CBD) was seen in 44% and the diameter was mean 3mm and maximum 11mm. CBD was located in extrapancreatic (75%) and lateral (60.6%0 to pancreatic head. At IVC-left renal vein level, the maximum distance between CBD and IVC was 5mm and the structure between posterior pancreatic surface and IVC was only fat tissue. Knowledge of these normal structures and measurement will be helpful in differentiating pancreatic mass with retropancreatic mass such as lymphadenopathy.

A rare case of traumatic bilateral anterior and posterior dislocstions of the hip wss occured by autamobile accident as a passenger injury. The right hip was dislocated anteroinferior to the righ scetabulum(neer the right obturator froamen), and the left hip was dislocated posterosuperior to the left acetsbulum with a ipsilateral femur head fracture caudsd to the fovea centralis(Fig. 1).

BACKGROUND: To provide some fundamental physiological basis for the physical training of pilots to improve orthostatic intolerance, cardiorespiratory responses to the symptom-limited maximal exercise loading were studied in pilots and non-pilots, and the results were compared. METHOD: Cardiorespiratory reponses to the symptom-limited maximal exercise loading by Bruce protocol was studied in 11 pilots and 11 matched controls (non-pilots). RESULTS: Comparisons of various data at maximal exercise in the pilots with those in the controls revealed that RR, VE/M2, VE/VO2, VE/VCO2, VT/VC and VE/MVV as well as HR, VO2, O2 pulse and AT showed no significant difference. CONCLUSION: The fact that the aerobic power in the pilots is not superior to that in the controls seems to emphasisze the necessity of aerobic endurance training along with muscular strength training to improve orthostatic tolerance of pilots flying modern high-performance aircrafts.

Hemangiopericytomas are very rare tumor in the paranasal sinuses. It is vascular tumor derived from Zimmerman's pericytes. Sinonasal hemangiopericytoma is generally benign with a low potential for local recurrence of metastasis via the blood stream and lymphatic system. They account for about 1% of all vascular tumors. About 5% of the cases occur in the nasal cavity and usually show well-differentiated tumors. The treatment of choice is surgical resection. We present a case of nasal hemangiopericytoma treated by endoscopic resection.

Tuberous sclerosis is a rare hereditary anomaly of variable penetrance characterized by mental retardation, epilepsy, and adenoma sebaceum. Pulmonary involvement is uncommon, but, when involve by tuberous sclerosis, it shows characteristic reticulonodular infiltration and cystic changes. Lymphangioleiomyomatosis is a rare disease of unknown cause that affects women of reproductive age. It is characterized by progressive proliferation of smooth muscle in the lung. We experienced one case of pulmonary lymphangioleiomyomatosis associated with tuberous sclerosis in a 26-year-old female patient. This case is reported with a brief of the literature.

Unilateral nevoid telangiectasia is a rare but clinica.lly distinct dermatosis first deacribed by Zeisler in 1922. It had been also called as linear telangiectasia or unilateral telangiectasia. Wilkin suggested the term unilateral dermatomal superficial telangiectasia, in 1977. There are some reports of congenital unilateral nevoid telangiectasia but it usually occurs in women during the puberty and the third decade. Clinically it is characterized by superficial telangiectatic lesions distributed along the dermatomes uniIaterally and usually on the upper part of the body. It was reported that unilateral nevoid telangiectasia was related with elevated serum estrogen level in the many cases. We present two patients, 23-year and 25-year-old male soldiers, whose leaions were consistent with unilateral nevoid telangiectasia elinically and histopathologically.
