STATEMENT OF PROBLEM: Proper proximal contact is important for maintaining and stabilizing the dental arch. However, the proximal contact strength (PCS) is not a constant value and can be affected by a variety of factors. PURPOSE: This study examined the influences of postural changes on the posterior PCS. MATERIAL AND METHODS: Twelve adults with a normal occlusion and had not undergone prosthetic treatment or proximal restoration were participated in this study. A metal strip was inserted into the proximal surface and removed at a constant velocity. The contact strength was measured in every contact point between canine to second molar in both arches. The PCSs were obtained initially in the upright position, secondly in the supine position and finally in the upright position again. All measurements were repeated after a 2 hour period. Statistical analysis was carried out using the Friedman test (P < .05). RESULTS: Generally, a decrease in PCS occurred when the posture was changed from the initial upright to supine position, while it increased when the posture was changed from the supine to upright position. A significant change was observed in all areas except for between the canine-first premolar in the maxilla and between the first molarsecond molar in the mandible areas. CONCLUSION: The posterior PCS, which dentists generally believe to be a static feature of occlusion, is affected significantly by posture.

Though the incidence of paragonimiasis has been remarkably decreased since 1970, it is still not a rare disease in Korea. Major problems in the diagnosis of pulmonary paragonimiasis on chest radiography are its differentiation from pulmonary tuberculosis and lung cancer. Chest radiographic findings have been described in detail, but little have been reported on CT findings. We reviewed CT findings of 10 patients with pulmonary paragonimiasis. The characteristic CT findings were similar to those on chest radiography, such as air-space consolidation (70%), nodular mass (50%), pleural effusion (40%), cystic lesion (30%), small low density within the mass (30%), linear density (20%), pneumothorax(20%), and burrow track (20%). CT depicted the cystic lesions and the burrow tracks more clearly and showed the small worm-retaining cysts within the mass that were not detectable on chest radiography. In conclusion, all of these CT findings are useful in the diagnosis of pulmonary paragonimiasis especially when differentiation from tuberculosis or lung canceris difficult on chest radiography.

BACKGROUND: Improved diagnostic and therapeutic strategies for infective for infective endocarditis such as proposed diagnostic criteria, Duke criteria and echocardiography resulted to increased life-spans of patients. METHODS: Retrospective analysis of medical records including medical history, laboratory data such as echocardiographic data and blood culture, and clinical outcomes was done for 106 patients with clinical diagnosis of infective endocarditis at Seoul National University Hospital from January 1990 to May 2000. Then we analysed differences of clinical features between elderly patients aged > or =60-years and the adult patients aged <60-years with infective endocarditis. RESULTS: The elderly patients >or=60-year are cases of 14%(15/106) and the mean ages are 67+/-8 years in elderly patient, 38+/-12 years in the adults patients respectively. Valvular heart disease was the most common predisposing heart disease with 9 cases(40%) followed by prosthetic valve endocarditis 2 cases (13%) in elderly patients, and there was no significant difference of frequencies with adult patients (valvular heart diseases, 33%; prosthetic valvular heart diseases, 25%). Although culture positive rates were not different with two groups: 47%(7/15) in elderly patients and 45%(41/91) in adult patients, the most common pathogen was staphylococcal species in elderly patients(27%, 4/15) but streptococcus species, in the adult patients(25%, 26/106, p<0.05). The frequencies of embolic complication were not different between two groups(20%, 3/15 vs 22%, 20/91: Elderly vs adult, respectively), but congestive heart failure was more developed in elderly patients, 33%(5/15) than in adult patients, 10%(9/91, p<0.05). Surgical intervention was more required in the elderly(47%, 7/15) than in adult patients(22%, 20/91, p<0.05). Out of 106 patients, 11 died and the overall mortality was 10.4%(11/106). In-hospital death was more common in the elderly than in adult patients: 4 cases(27%) vs 8%(7/91), p<0.05. Determinants of in-hospital death were patients with 60 years of age and older, Staphylococcus aureus endocarditis, and the presence of congestive heart failure(p<0.05) in univariate analysis. CONCLUSION: Infective endocarditis in elderly patients(age> or =60) had more poor outcomes than adult patients(age<60) such as the development of congestive heart failure, the need of surgical intervention, and the high mortality rate.

BACKGROUND: The primary outcome of sugammadex reversal for rocuronium-induced neuromuscular block (NMB) is a train-of-four ratio (TOFR) of 0.9, not first twitch (T1) height. We investigated whether the recovery of TOFR or T1 differs based on the reversal of NMB with neostigmine or sugammadex. METHODS: The acceleromyographic responses from 0.6 mg/kg of rocuronium were monitored supramaximally in 80 patients after induction of anesthesia. The TOFR and T1 height were recorded, and saved in a personal computer using TOF-Watch SX Monitor software in all patients. Patients were randomly assigned to 2 groups to receive either neostigmine 50 µg/kg with glycopyrrolate 10 µg/kg (neostigmine group, n = 40) or sugammadex 2.0 mg/kg (sugammadex group, n = 40). The primary objective was to determine the difference of recovery time between TOFR to 0.9 and T1 to 0.9 after sugammadex or neostigmine administration during moderate rocuronium-induced NMB. RESULTS: The recovery pattern of the TOFR 2 min after sugammadex administration was 1.0 or more, but that of T1 was less than 90% (T1 / control value) up to 6 min after drug was injected. The recovery pattern of TOFR and T1 was similar during the 20 min after reversal with neostigmine. CONCLUSIONS: If you have not performed the T1 monitoring, both TOFR and T1 should be considered to confirm suitable recovery during the 6 min after reversal with sugammadex during rocuronium-induced moderate NMB.
