Urea reduction ratio (URR) and Kt/Vurea are objective parameters of dialysis delivery in hemodialysis patients and correlate with nutritional status and patient outcome. URR and Kt/Vurea depend on postdialysis blood urea nitrogen (BUN). In patients with severe postdialysis urea rebound (PDUR), these parameters do not accurately reflect dialysis adequacy. We measured PDUR 30 minutes after dialysis in 26 chronic stable hemodialysis patients. The impact of PDUR on dialysis delivery assessed by URR and Kt/Vurea and the independent factors affecting on PDUR were evaluated. All patients had been dialyzed for 4 hours thrice a week using hemophan membrane. 1) The mean age of patients was 48.6+/-14.8 years and sex ratio was 1:2.3. The mean duration of hemodialysis was 42.7+/-45.0 months. Primary renal diseases were chronic glomerulonephritis 11 (42.3%), diabetic nephropathy 7 (26.9%), and hypertension 4 (15.4%). 2) The mean blood flow was 209.2+/-17.4ml/min. URR, Kt/Vurea, and nPCR using immediate postdialysis BUN were 60+/-7%, 1.13+/-0.21, 1.09+/-0.28g/kg/ day, respectively. The mean recirculation rate was 4.4+/-2.3%. 3)The mean PDUR was 12.2+/-4.6% (range:6-22 %). URR, Kt/Vurea, and nPCR using BUN 30 minutes after dialysis were 55+/-7%, 0.99+/-0.18, and 1.02+/-0.25 g/kg/day, respectively and were significantly lower than those using immediate postdialysis BUN (P<0.05). 4) When the patients were divided according to the degree of PDUR (low PDUR group:<12%, high PDUR group: > or = 12%), high PDUR group was significantly higher than low PDUR group in hematocrit (27.0+/-2.6 vs. 23.5+/-3.6%, P=0.008), URR (64.3+/-5.4 vs. 55.8+/-6.8%, P=0.002), Kt/Vurea (1.26+/-0.17 vs. 1.03+/-0.18, P=0.002), and total recirculation rate (5.6+/-2.7 vs. 3.6+/-1.7%, P=0.05). There were no differences in age, sex, postdialysis body weight, ultrafiltration rate, blood flow, serum albumin, predialysis BUN, creatinine, and nPCR. 5) In multiple regression analysis, the independent factors affecting on PDUR were Kt/Vurea (beta=0.546, P<0.001), recirculation rate (beta=0.422, P<0.001), and hematocrit (beta=0.366, P=0.0017). In conclusion, we think that PDUR should be considered in hemodialysis patients when estimating dialysis delivery, especially if they had high Kt/ Vurea, recirculation rate, and hematocrit.

This study was aimed to comprehend the pattern of renal response in bicarbonate reabsorption during various alterations in acid-base equilibrium in twelve dogs. In metabolic acidosis induced by infusion of hydrochloric acid, as the plasma bicarbonate and filtered load of bicarbonate decreased eminently, urinary excretion of bicarbonate was found to be negligible. which was attributable to almost complete reabsorption via the hydration of CO2. In metabolic alkalosis induced by infusion of sodium bicarbonate, along with an increment of plasma concentration of bicarbonate, all filtered bicarbonate was reabsorbed, with negligible amount of excretion until the plasma level attains the renal bicarbonate threshold. During the respiratory acidosis and alkalosis with higher or lower arterial Pco2, the bicarbonate reabsorption varied linearly with plasma Pco2. The linear relationship indicated that the hydration of CO, was an important source of hydrogen ion for the reabsorption of bicarbonate. In this regards, however, in metabolic alkalosis the renal bicarbonate threshold was found to be much higher than that of respiratory acidosis. The characteristics of renal bicarbonate reabsorption, during the mixed acid-base disturbances of metabolic and respiratory origin with no considerable alteration of plasma pH, induced by hydrochloric acid infusion with hyperventilation or sodium bicarbonate infusion with CO2 inhalation, were quite similar to those in metabolic acidosis and alkalosis caused by simple hydrochloric acid or sodium bicarbonate infusion, respectively.

Two cases of vertebra plana due to eosinophilic granuloma were experienced and successfully treated by anterior fusion of the involved spines at the department of Orthopedic Surgery in Seoul National University Hospital. Literature on the subject was reviewed.

Combined injury of peroneus brevis rupture and bimalleolar fracture is very rare. The avulsion of peroneus brevis tendon from insertion maybe neglected and may prevent anatomic reduction of lateral malleolar fracture. We have treated open bimalleolar fracture with avulsion of peroneus brevis tendon from its insertion.

Seidel nail is one of locked humeral nail and Seidel himself reported excellent result in his preliminary report using his nail. But our early experience showed disappointing result with high rate of complications, So we reviewed our 16 cases of humeral shaft fracture with polytrauma treated with Seidel nail and studied anatomical fitness of the nail within the distal medullary space using CT scan. The most frequent complication was intraoperative fracture of the proximal humerus < 4 cases> and this seemed to be due to lateral placement of pilot hole. There were 3 cases of nonunion and these cases showed insufficient distal anchorage, either primarily or postoperatively. Anatomical fitness study showed insufficient spreading of nail flanges in 5 cases of distal canal width below 9mm and nonunion cases were in this group. Other problems of Seidel nail were technical difficulties due to occasionally incorrect proximal targeting device and frequent breakage of adaptor screw. Study of more cases may be needed to confirm the design problem of Seidel nail.

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.
