We analysed the 49 probands of autosomal dominant polycystic kidney disease (ADPKD) in Korea to elucidate clinical and genetic characteristics. 1) Family history of renal disease or ADPKD was taken from 44% of probands; hypertension 88%, cerebrovascular attack 64%, end stage renal disease 16%. 2) From the family screening with renal ultrasonography, we have confirmed dominant trait in 24 families. We found 2 families which have suspicious new mutations. 3) We performed linkage analysis of 15 families. The PKD-1 to non PKD-1 ratio was 13 : 2. 4) The male to femal ratio was 17 : 32 and age at diagnosis was 41 (24-65)years (mean (range)) in male, 45 (26-68) years in female. 5) The factors leading to the diagnosis of ADPKD were flank pain (23%), incidental finding (17%), palpable abdominal mass (11%), headache (9%) and gross hematuria (9%) 3) Hypertension (80%), azotemia (43%), flank pain (42%), renal calcification (42%), gross hematuria (33%) and cyst hemorrhage (25%) were renal complications. There were 2 renal cell carcinoma cases. 4)Liver cyst (82%) was the most common extrarenal manifestations. There were colonic diverticulosis (13%), cerebral artery aneurysm (7%), adrenal cyst (4%) and pancreatic cyst (2%). Results of our study revealed the clinical and genetic characteristics of ADPKD in Korea. We found only 44% of family history of renal disease, variable initial manifestations, variable renal and extrarenal complications. And we also found the similar percentage of PKD-2 (13%) to that (5-15%) of western countries, but it is necessary to study with more patients and families.

OBJECTIVES: This study examined the influence of different sizes of spoons (normal spoon, 8.3 cc vs small spoon, 4 cc) on eating rate, energy intake and the satiety levels of female college students. METHODS: Twenty four healthy female college students participated in this study once a week for 2 weeks. Two hundred ten grams of cooked rice and 250 g of beef shank soup with a normal spoon and same amount of rice and soup with a small size spoon were served to the same participants over two consecutive weeks. After each lunch, the eating rate, energy intake, and the satiety levels were measured. RESULTS: Results showed that the subjects who were using a small spoon ate less beef shank soup (149.0 kcal) (p < 0.01) and had lower total energy intake (423.3 kcal) (p < 0.05) than using a normal spoon (178.7 and 461.1 kcal, respectively). Also, the meal time (15.7 min) (p < 0.01), a serving per one spoon (8.6 g) (p < 0.001), and eating rate (27.9 g/min) (p < 0.001) of those who used a small spoon were significantly different than that of those who used a normal spoon (13.6 min, 12.5 g and 35.7 g/min, respectively). However, despite consuming less energy at lunch, the level of satiety after eating from the small spoon was not significantly different from the normal spoon immediately after, 1 hour after and 2 hour after lunch. CONCLUSIONS: Our results revealed that students were able to control their eating rate by using a small spoon and they could feel full enough even though they eat less. In conclusion, eating rate decrease by using a small spoon may play an important role in food intake.

BACKGROUND: The pathogenesis of ADPKD is still unknown but the proliferation of cystic epithelia and the fluid secretion to cystic lumen are thought to be important. Cytokines play a pivotal role in growth, differentiation, and apoptosis in general, but there were few reports about the cytokine profile in ADPKD cysts. METHODS: In this study, we measured cytokine content in aerobic culture-negative cystic fluids from 23 patients with symptomatic normal to end-stage (n=3) ADPKD in order to elucidate the possibility that cytokines are related to the development and progression of disease. Enzyme-linked immunosorbent assays (ELISAs) were used to detect IL-1beta, IL-2, IL-4, IL-6, IL-10, and IFN-gamma with commercial kits. RESULTS: Male to female ratio was 6 : 17 and the median age at examination was 52 years (range 36 to 78). IL-1beta was present in 18 of 23[78%] (11 to 173 pg/mL), IL-2 in 18 of 23[78%] (5 to 159 pg/ mL), IL-4 in 9 0f 23[39%] (8 to 156 pg/mL) and IL-6 in 10 of 23[43%] (16 to 1498 pg/mL). IL-10, and IFN-gamma were not detected. IL-1beta concentrations correlated directly with those of IL-2 (r=0.7671). IL- 6 levels in patients with azotemia (n=7) [288.4+/-26.2 (mean+/-S.D.)] were significantly higher than those of normal renal function group (98.3+/-413.9)(p<0.01). Such difference was not found in other cytokines. Cytokine concentrations did not correlate with sodium concentrations, nor with cystic fluid osmolality, indicating that differences in concentrations among fluids could not be explained by differences in water content. And, there was no significant correlation between the intracystic concentrations of these cytokines and the corresponding cyst diameters. CONCLUSION: These data identify proinflammatory cytokines as possible mediators to the morbidity of ADPKD. Especially, IL-6 levels of cystic fluid were elevated in the azotemic ADPKD patients.

A 57-year-old woman who had a history of diabetes was admitted due to fever and left flank pain. Acute pyelonephritis was diagnosed by clinical findings including left costovertebral area tenderness, positive urine and blood cultures. Subsequent abdominal computed tomography demonstrated multiple abscess pockets in the left renal parenchyme and ipsilateral renal vein thrombosis. She was fully recovered after treatment with antibiotics, low-molecular weight heparin and low-dose aspirin for six weeks. Our case emphasizes that renal vein thrombosis could be complicated in acute pyelonephritis, especially in patients with diabetes. It is reasonable to speculate that factors such as hemoconcentration caused by fever and osmotic diuresis and compression of renal vascular pedicle by renal abscess might have had a role in inciting the renal vein thrombosis.

Hepatitis B virus(HBV) infection has been suggested as the etiologic agent in membranoproliferative glomerulonephritis(MPGN), but the mechanism by which HBV infection leads to MPGN in human has not been established. To localize the HBV antigen and HBV-DNA in the kidney tissue, we examined paraffin sections of kidney biopsies which were positive for HBsAg by immunohistochemical study from 13 HBV carriers with MPGN (HBV-MPGN). Polymerase chain reaction(PCR) and in situ PCR(ISP) were used for the HBV DNA amplification and localization in kidney tissues. Primers used in PCR and ISP were from the S, C, and X HBV-DNA regions. Immunohistochemical study showed HBsAg deposits on the mesangium and glomerular capillaries. Arteriolar deposits were also occasionally observed. PCR for the S, C, and X regions were positive in 11 patients(85%), 11 patients(85%), and 9 patients (69%), respectively. The PCR findings were further confirmed by direct sequencing of PCR products and the amplification of HSP70 gene as a control. ISP showed the amplified HBV-DNA at the glomeruli and renal tubules. For S region, ISP was positive in 7 patients. For C and X regions, ISP was positive in 8 patients, respectively. 5 patients showed the positive signals for both the glomeruli and tubules, while 4 patients were positive at the tubules only. These 4 patients seemed to have the longer disease durations when compared to the other 5 patients (52.8 months vs. 11.8 months), but it was not statistically significant. In conclusion, the detection and the localization of HBV antigen and DNA in renal tissues indicate the presence of the complete virion in the kidney. These results suggest that HBV may infect the kidneys of HBV carriers with MPGN.

The purpose of this study was to evaluate the result after 2-phase surgical-orthodontic treatment without preoperative orthodontic treatment for the skeletal Cl III malocclusion patient and to obtain an adequate protocol on the bases of this result. This retrospective study of ten patients who underwent 2-phase treatment were done to evaluate 1) the surgical stability and relapse pattern 2) the facial esthetics 3) the TMJ problem 4) the total time of the treatment. Results were followed : 1) The horizontal relapse of the mandible was 26.8% and didn't show significant differences compared to the conventional 3-phase treatment. But, it was considered that this amount of relapse was the sum of true relapse and autoratation of mandible due to decreased vertical dimension during orthodontic treatment. 2) It was estimated that there's no difference on the ratio of anterior facial height between the subjects and the normal patients. On the horizontal analysis, the mandible of the subjects was located more anteriorly than that of the normal patients. This result showed that there was a need for the accurate preoperative esthetic evaluation and the additional methods for reducing the relapse due to the occlusal interference. 3) Wide variation was noted on the TMJ symptoms of the subjects, however, it was estimated that there's no significant differencees of symptoms compared to that of the conventional 3-phase treatment on literatures. 4) The average of the overall period of treatment was 20.8 months and we obtained reduction of the treatment time compaired to 3-phase treatment on many literatures. Most of the results of this study were similar to the findings of the 3-phase treatment(preoperative orthodontic-orthognathic surgery-postoperative orthodontic), but total time of the treatment was shorter in patients with 2-phase treatment than in those with the conventional 3-phase treatment. With 2-phase treatment, we experienced many advantages compared to the conventional method considering that it was favarable conditions for the teeth, it had the flexibility for the treatment, and it could be the adequate treatment approach for the stomatognathic system. Although this retrospective pilot study had some limitations, due to small samples, the authors would hope that it could serve as a guide for the future reaearches, and the clinical applications.

Background: This study aimed to identify the relationship between gait parameters and health-related quality of life (HRQOL) in patients with ankylosing spondylitis (AS). Methods: The study group comprised 134 patients with AS and 124 patients were enrolled as controls. All study participants underwent instrumented gait analysis and completed clinical questionnaires. The kinematic parameters of gait were walking speed, step length, cadence, stance phase, single support, double support, phase coordination index (PCI), and gait asymmetry (GA). For each patient, a visual analog scale (VAS; 0–10) score was used to assess back pain, 36-item short form survey (SF-36) questionnaire was administered to evaluate the HRQOL, and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) was calculated.Using kinematic parameters and questionnaires, statistical analyses were done to investigate significant differences between the groups. Relationship of gait kinematic data and questionnaires of clinical outcome was also evaluated. Results: Among the 134 patients with AS, 34 were women and 100 were men. In the control group, 26 were women and 98 were men. The patients with AS and control group patients had significant differences in terms of walking speed, step length, single support, PCI, and GA. However, such differences were not observed in cadence, stance phase, and double support (p > 0.05). In correlation analyses, gait kinematic parameters and clinical outcomes were significantly related with each other. In multiple regression analysis performed to identify predictive factors for clinical outcome, walking speed was found to predict VAS, and walking speed and step length were found to predict the BASDAI and SF-36 scores. Conclusions Patients with and without AS had significant differences in the gait parameters. Correlation analysis showed significant correlation between the gait kinematic data and clinical outcomes. In particular, walking speed and step length successfully predicted clinical outcomes in patients with AS.
