Purpose:
To investigate the differences in the frequency of post-fitting denture check-ups based on gender, age, insurance status, denture arch, and type among patients aged 65 and above.
Methods:
This research analyzed 988 patients from National Health Insurance Service Ilsan Hospital’s Department of Prosthodontics, who had denture fittings over the last 10 years. Variables including gender, age, insurance status and type, denture arch, and denture type were assessed. Statistical analyses were performed at a 5% significance level.
Results:
The study incorporated 988 dentures, revealing a median of 3 check-ups post-fitting. Male patients significantly had more visits than females (P = .017), and those with full metal dentures visited significantly more than those with partial dentures (P = .005). Other variables were not significantly influential on the post-fitting check-up frequency.
Conclusion
Within this study’s confines, an increase in denture adjustment sessions was observed for male patients and those with full metal dentures.

BACKGROUND/AIMS: Multiple myeloma (MM) is frequently accompanied by renal insufficiency, which has been regarded as a poor prognostic factor for MM. It is known that the incidence and characteristics of MM in Asia differ from those in Western countries. The aim of this study was to evaluate risk factors for renal impairment and to investigate reversible factors for renal failure in patients with MM. METHODS: Patients newly diagnosed with MM from 2005 to 2008 were included. We investigated factors associated with renal insufficiency and those related to recovery from renal dysfunction after 12 weeks of treatment of MM. RESULTS: Renal failure was recognized in 86 (39%) of 221 patients at diagnosis. In the binary logistic regression analysis, low hemoglobin (odds ratio [OR], 0.813; p = 0.02), high beta2microglobulin (OR, 1.006; p < 0.01), and use of angiotensin-converting enzyme inhibitors (ACEi) (OR, 2.783; p < 0.04) at initial presentation were independent risk factors for renal failure in patients with multiple myeloma. After 12 weeks of treatment, 25 of 86 (29%) patients with renal failure had recovered renal function. Good response to chemotherapy (OR, 6.044; p < 0.01) and higher eGFR (OR, 1.084; p < 0.01) were associated with renal function recovery. CONCLUSIONS: Levels of hemoglobin and beta2microglobulin, and use of ACEi were independent risk factors for the development of renal failure in MM patients. The response to chemotherapy and eGFR at diagnosis significantly influenced recovery of renal function.

This study evaluated the significance of aortic calcification index (ACI), an estimate of abdominal aortic calcification by plain abdominal computed tomography (CT), in terms of left ventricular (LV) diastolic dysfunction, mortality, and nonfatal cardiovascular (CV) events in chronic hemodialysis patients. Hemodialysis patients who took both an abdominal CT and echocardiography were divided into a low-ACI group (n = 64) and a high-ACI group (n = 64). The high-ACI group was significantly older, had a longer dialysis vintage and higher comorbidity indices, and more patients had a previous history of CV disease than the low-ACI group. The ACI was negatively correlated with LV end-diastolic volume or LV stroke volume, and was positively correlated with the ratio of peak early transmitral flow velocity to peak early diastolic mitral annular velocity (E/E' ratio), a marker of LV diastolic function. The E/E' ratio was independently associated with the ACI. The event-free survival rates for mortality and nonfatal CV events were significantly lower in the high-ACI group compared with those in the low-ACI group, and the ACI was an independent predictor for all-cause deaths and nonfatal CV events. In conclusion, ACI is significantly associated with diastolic dysfunction and predicts all-cause mortality and nonfatal CV events in hemodialysis patients.

It has been shown that QGC isolated and purified from Rumecis folium found protective effects of gastritis and esophagitis which EXT is an ethanol extract of it. We examined acute toxicity and the general pharmacological action of QGC EXT to search for any side effects of it in rats, mice, guinea pigs, and cats. In a single dose toxicity study, QGC EXT didn't show toxicological effects in rats and mice, and the LD50 was over 5 g/kg in both animals, and there were also no changes in weight, feed and water intake during these toxicological experimental periods. We examined the general pharmacological action on central controlled behavior responses, and peripheral organs including blood pressure, heart rate, respiration and gastrointestinal system, We found that there were no significant changes in body temperature, locomotors activity, stereotyped behaviors, sleeping time, and convulsion. In other studies, writhing reaction, normal body temperature, there did not appear to be any changes. The large intestine movement and electrical field stimulation-induced contraction was not changes by its EXT. In addition, the influences on blood pressure, heart rates, and respiration by QGC EXT were not found. These results indicate that QGC EXT may be very safe as a new drug, since its LD50 was very high over 5 g/kg and any side effects were not found.

BACKGROUND AND OBJECTIVES : Microvascular integrity has been associated with the clinical outcomes in acute myocardial infarction (AMI). The present study was conducted to determine the value of many microvascular indexes assessed by an intracoronary (IC) pressure/Doppler wire in AMI following primary PCI for detecting viable myocardium by comparing with the 18F-fluorodeoxyglucose uptake rate (%FDG uptake) on positron-emission tomography (PET). SUBJECTS AND METHODS : We studied 35 patients who had their first AMI (age: 56+/-12, male: 30). After primary PCI, the TMPG (TIMI myocardial perfusion grade) was assessed. We measured the coronary flow reserve (CFR), the diastolic deceleration time (DDT), the coronary wedge pressure (Pcw), the Pcw/ Pa (mean aortic pressure) and the hyperemic microvascular resistance index (hMVRI) by an IC Doppler/ pressure wire. 18FDG PET scan was obtained at 7 days after the primary PCI; viable myocardium was defined that the %FDG uptake was more than 50% in infarct-related myocardium. RESULTS : There were significant correlations between TMPG, CFR, Pcw, Pcw/Pa, DDT, hMVRI and %FDG uptake (r=0.651, p<0.001; r=0.386, p=0.020; r=-0.388, p=0.021; r=-0.473, p=0.004; r=0.589, p<0.001; r=-0.442, p=0.008, respectively). The best cutoff values and area under curves (AUC) of the CFR, Pcw, Pcw/Pa, DDT and hMVRI for 50% FDG uptake were 1.8 (0.737), 27 mmHg (0.600), 0.33 (0.660), 600 msec (0.802) and 2.55 mmHg.cm-1.sec (0.768), respectively. The DDT had a significantly higher AUC than that of Pcw (p=0.029) and it was an independent index to predict the myocardial viability (p=0.011). CONCLUSION : DDT was the most reliable hemodynamic microvascular index that was assessed within 24 hours following primary PCI for predicting the viable myocardium in AMI patients.

Granulocytic sarcoma is an uncommon clinical condition that usually occurs in the bone, periosteum, soft tissue, lymph node and skin, and this is rarely seen in the gastrointestinal tract. To the best of our knowledge, few cases of granulocytic sarcoma in the small bowel have been reported in the English literature. We present here a case of nonleukemic granulocytic sarcoma of the ileum in a 42-year-old patient who had no evidence of blood or bone marrow involvement that would have been suggestive of acute leukemia or myeloproliferative disorders.

OBJECTIVE: To evaluate the effectiveness of Novalis shaped beam radiation treatment as an adjuvant treatment in patients with craniopharyngiomas. METHODS: We reviewed 8 patients with craniopharyngiomas who had recurring tumors during follow-up or had residual lesions after primary surgery. Three of 8 patients were found to have recurrence after gross total excision of the tumor and 5 patents had residual lesions after subtotal resection. All patients were treated with fractionated stereotactic radiation treatment(FSRT) using Novalis system. The mean age of patients was 28 years (range 16~52). The median irradiation dose per fraction was 1.7Gy (range 1.7~2.0). The median fraction number was 23 (range 15~25), and the median total dose was 39.1Gy (range 25.5~42.5). Follow-up included MR imaging, and ophthalmologic and endocrine examinations. RESULTS: The median follow-up period was 23 months (range 12~43). The local tumor control rate was 87.5%. One patient had a recurring tumor, in which cystic change developed 2 months after FSRT. Four patients showed a decrease in size of their tumor, while 3 patients remained stable. Seven out of 8 patients had hormonal dysfunction that remained unchanged after initial surgery. No further progression of visual impairment was observed. CONCLUSION: FSRT using Novais system is effective and safe for the treatment of recurring or residual craniopharyngiomas without toxicity like optic neuropathy.

OBJECTIVE: We treated 10 pediatric diffuse intrinsic brain stem glioma(BSG) patients with Novalis system (linac based radiotherapy unit, Germany) and examined the efficacy of the Fractionated Stereotactic Radiotherapy(FSRT). METHODS: A retrospective review was conducted on 10 pediatric diffuse intrinsic BSG patients who were treated with FSRT between May, 2001 and August, 2004. The mean age of the patient group was 7.7 years old. Male to female ratio was 4 to 1. The mean dose of FSRT was 38.7Gy, mean fractionated dose was 2.6Gy, mean fractionation size was 16.6, and target volume was 42.78cm3. The mean follow up period was 14 months. RESULTS: Four weeks after completion of FSRT, improvements on neurological status and Karnofsky performance scale(KPS) score were recorded in 9/10 (90%) patients and magnetic resonance imaging(MRI) showed decrease in target tumor volume in 8 pediatric patients. The median survival period was 13.5 months after FSRT and treatment toxicity was mild. CONCLUSION: It is difficult for surgeons to choose surgical treatment for diffuse intrinsic BSG due to its dangerous anatomical structures. FSRT made it possible to control the tumor volume to improve neurological symptoms with minimal complications. We expect that FSRT is a feasible treatment modality for pediatric diffuse intrinsic BSG with tolerable toxicities.

Fibrolamellar hepatocelluar carcinoma is a distinct clinicopathologic variant of hepatocellular carcinoma. We describe here the sonographic and CT findings of fibrolamellar hepatocellular carcinoma in a 17-year-old patient that mimicked hepatic malignant lymphoma due to the multiple small hypoattenuating nodules and extensive lymphadenopathy that we observed. We also include a review of the relevant literatures.
