Metabolic acidosis (MA) is associated with increased proteolysis, increased osteoclast activity and blunted cardiac muscle response, but the effect of MA on various clinic al parameters in CAPD patients is not well known. To evaluate the effects of MA on serum albumin level and other nutritional parameters in CAPD patients, we studied 106 CAPD patients retrospectively who have had monthly biochemical measurement and urea kinetic studies every 6 months for more than 2 years. The patients were divided into three groups according to their mean total CO2 (tCO2) level of the 2-year follow-up (Group l; mean tCO2 < 22mM/L, Group ll; 22mM/L < or = mean tCO2 < 26mM/L, and Group lll; mean tCO2 > or = 26mM/L), and the clinical, biochemical, and urea kinetic data were compared among the three groups. 1)The mean age of the subjects was 46.9+/-12.2 years with a sex ratio of 1.2:1, the mean CAPD duration 28.3+/-21.8 months, mean body weight (Bwt) 59.0+/-8.9kg, %Bwt/IBW 104.1+/-11.5%, %LBM/Bwt 75.5+/-11.1% and well-nourished patients by subjective global assessment (SGA) were 65%. 2)The mean BUN, creatinine, total protein and albumin of all patients were 55.6+/-13.6mg/dL, 12.3+/-3.5mg/dL, 6.6+/-0.7g/dL and 4.0+/-0.4g/dL, respectively. In urea kinetic study, the mean NPCR, weekly Kt/ Vurea, SCCr and RRF were 0.96+/-0.16g/kg/day, 2.02+/-0.37, 63.7+/-18.4L/week/1.73m2, and 0.99+/-1.32ml/ min, respectively. 3)The mean age was significantly higher in group l (51.0+/-10.8) than those of group ll (47.0+/-12.4) and lll (42.6+/-11.4) (P<0.05). %Bwt/IBW of group l (114.4+/-15.8%) was also significantly higher than those of group ll (104.6+/-12.6%) and lll (103.5+/-13.7 %) (P<0.05), but there were no significant differences in sex ratio, CAPD duration, %LBM/Bwt, and SGA among the three groups. 4)The mean tCO2 in group l, group ll, and group lll were 20.6+/-1.2mM/L, 23.9+/-1.1mM/L, and 27.3+/-0.8mM/L, respectively. Compared to group lll, group l had significantly higher BUN (61.1+/-14.3 vs. 46.1+/-7.2mg/dL, P<0.05) and serum albumin (4.04+/-0.31 vs. 3.75+/-0.39g/dL, P<0.05), in spite of comparable dialysis dose and albumin loss into dialysate. 5)NPCR (1.02+/-0.21g/kg/day vs. 0.88+/-0.14g/kg/ day, P<0.05) and ultrafiltration volume (1.4+/-0.4 vs. 1.0+/-0.3, P<0.05) were significantly higher in group l than those of group lll. But there were no significant differences in Kt/Vurea, SCCr, RRF, and 24-hour dialysate loss of protein/albumin among the three groups. 6)No differences were observed among the three groups in the changes of body weight, %Bwt/IBW, %LBM/Bwt, BUN, albumin, NPCR, and RRF from the baseline values after the 2-year follow-up. 7)There were significant inverse correlations between the mean tCO2 level and NPCR (r=-0.33, P<0.001), %Bwt/IBW (r=-0.32, P<0.001), RRF (r=-0.29, P<0.005), and serum albumin level (r=-0.24, P<0.05). But, creatinine, %LBM/Bwt, and Kt/Vurea did not show any correlation with the mean tCO2 level. 8)Using stepwise multiple regression analysis, NPCR (beta=-0.3491, P<0.001), %Bwt/IBW (beta=-0.046, P<0.001), and ultrafiltration volume (beta=-0.0012, P< 0.005) were independent factors affecting the mean tCO2 level. In conclusion, low total CO2 level in long-term CAPD patients may reflect increased protein intake and mild to moderate degree of metabolic acidosis may not affect the nutritional status of well-dialyzed CAPD patients.

PURPOSE: To analyze the morphology and density of corneal tissue in patients with early stage Fuchs' corneal endothelial dystrophy (FCED) by in vivo confocal microscopy (IVCM). CASE SUMMARY: Each layer of the cornea in 2 patients with early-stage FCED was examined with IVCM (ConfoScan 4.0, NIDEK, Co. Ltd., albignasego, Italy). Cross-sectioned corneal images of the corneal epithelium, Bowman's layer, stromal layer, Descemet's membrane, and endothelium were evaluated. Corneal epithelium, Bowman's layer, and anterior stroma of both patients showed no abnormalities. Case 1 was diagnosed as Stage 1 FCED, demonstrating typical changes including pleomorphism, polymegathism, and the presence of guttae in the corneal endothelial layer. Case 2 was diagnosed as Stage 2 FCED, showing several hyper-reflective whitish dots in the posterior stroma, hypo-reflective vertical strands in the stroma adjacent to Descemet's membrane, and pleomorphism, polymegathism, and guttae in the corneal endothelial layer. CONCLUSIONS: IVCM is a non-invasive and effective tool to diagnose early-stage FCED.

We report a case of calcific bursitis of the shoulder in four-year-old boy who had severe pain and limitation of motion of the left shoulder joint for three days. Radiographs revealed the oval radiopaque lesion in the subacormial space, and the MR signal intensity of the mass was moderate on T2WI. Histological examination of the mass showed acute necrotizing inflammation with calcification.

PURPOSE: To evaluate prognostic factors for arthritis and usefulness of bone SPECT in reconstructed joint. MATERIAL AND METHOD: ACL reconstruction using bone-patellar tendon-bone graft was performed in fourteen patients from March 1996 to March 1997, and follow-up bone SPECT was done. The mean duration from ACL reconstruction to SPECT was 23 months. The knee was defined to be unstable when the difference of displacement measured using KT-2000 arthrometer was greater than 3 mm. Lesions were evaluated in sub-divided five compartments ; patello-femoral joint, anteromedial, anterolateral, postero-medial and posterolateral compartment of tibio-femoral joint. RESULT: Geographic bone bruise was found in 9 cases(15 compartments) of 14 patients and bone SPECT revealed increased uptake in all the compartments. Reticular type bone bruise was found in 6 cases(7 compartments) and no compartment revealed increased uptake. Partial meniscectomy was done in 9 cases(16 compartments), and 8 cases(13 compartments) of them revealed increased uptake. Six cases were unstable and four of them revealed increased uptake in the patello-femoral joint. Activity level was not correlated with hot uptake. CONCLUSIONS: Bone SPECT is a useful method to predict osteoarthritis after ACL reconstruction. Geo-graphic bone bruises at injury, meniscectomy and instability are important factors for prognosis after ACL reconstruction.

Identifying and preventing modifiable risk factors for cardiovascular disease is very important. Vascular calcification has been studied clinically as an asymptomatic preclinical marker of atherosclerosis and a risk factor for cardio-cerebrovascular disease. It is known that higher homocysteine levels are associated with calcified plaques and the higher the homocysteine level, the higher the prevalence and progression of vascular calcification. Homocysteine is a byproduct of methionine metabolism and is generally maintained at a physiological level. Moreover, it may increase if the patient has a genetic deficiency of metabolic enzymes, nutritional deficiencies of related cofactors (vitamins), chronic diseases, or a poor lifestyle. Homocysteine is an oxidative stress factor that can lead to calcified plaques and trigger vascular inflammation. Hyperhomocysteinemia causes endothelial dysfunction, transdifferentiation of vascular smooth muscle cells, and the induction of apoptosis. As a result of transdifferentiation and cell apoptosis, hydroxyapatite accumulates in the walls of blood vessels. Several studies have reported on the mechanisms of multiple cellular signaling pathways that cause inflammation and calcification in blood vessels. Therefore, in this review, we take a closer look at understanding the clinical consequences of hyperhomocysteinemia and apply clinical approaches to reduce its prevalence.

The ectopic eruption of teeth into the nasal cavity is a rare phenomenon. Ectopic tooth eruptions commonly occur in the palate and maxillary sinus, but have also been reported in the mandibular condyle, coronoid process, orbit, and nasal cavities. The clinical manifestations of intranasal teeth are quite variable; however, intranasal teeth can be an incidental finding during routine examination in patients without nasal discomfort. Herein we report a unique case of an intranasal ectopic tooth that erupted into the nasal cavity and caused significant nasal symptoms in an otherwise healthy patient. The intranasal tooth was removed endoscopically.
