Pharmacokinetics of oral alminoprofen (Minalfen) in elderly patients with rheumatoid arthritis and spondylosis deformans]

The pharmacokinetics of oral Alminoprofen, a nonsteroidal anti-inflammatory drug, were studied in five elderly patients with rheumatoid arthritis and spondylosis deformans after 200 mg (three times a day) repeated dose for 5 days. The pharmacokinetic parameters after oral administration of Alminoprofen were analyzed by the one-compartment open model method. The maximum plasma concentrations (Cmax) were 16.1 +/- 2.5 micrograms/ml, after dosing on day 1, 25.2 +/- 1.6 micrograms/ml on day 3 and 21.6 +/- 2.7 micrograms/ml on day 5. The maximum time (Tmax) were about 2 hours after the medication in al cases. The area under the curve in drug concentration in plasma versus time (AUC) were 58.5 +/- 6.3 micrograms hr/ml on day 1, 58.5 +/- 3.1 micrograms hr/ml on day 3 and 58.1 +/- 8.5 micrograms hr/ml on day 5. The biological half-lives (t1/2) were 2.45 +/- 0.35, 2.09 +/- 0.82 and 2.49 +/- 0.63 hours, after dosing on day 1, day 3 and day 5, respectively. The analysis of moment in pharmacokinetics revealed that the mean residence time (MRT) on day 1, day 3 and day 5 observed were 2.31 +/- 0.03, 2.15 +/- 0.09 and 2.15 +/- 0.07 hours, respectively. The variance residence times (VRT) observed were 0.95 +/- 0.05 hour2 on day 1, 0.88 +/- 0.09 hour2 on day 3 and 1.06 +/- 0.07 hour2 on day 5. The ratios of accumulation calculated were 1.16 +/- 0.05 in both the morning medication on day 3 day 5, and it therefore appears that the steady-state equilibrium is established within 3 days after commencement of dosage.(ABSTRACT TRUNCATED AT 250 WORDS)     

Surgical repair of total anomalous pulmonary venous connection in neonates and infants--prevention for pulmonary venous obstruction at the site of anastomosis

From October, 1980, to June, 1987, thirty-eight infants less than one year old underwent correction for total anomalous pulmonary venous connection (TAPVC). Overall operative mortality and late mortality were 13% and 6%, respectively. Residual pulmonary hypertension was noted in 4 patients: three had pulmonary venous obstruction at the site of atrial anastomosis (PVOA) and one had supracardiac (Ia) lesion left after repair of mixed type (IV: Ia + III) of TAPVC. Two late deaths occurred in these with PVOA. Twenty-two patients with supracardiac (I) or infracardiac (III) TAPVC were divided into three groups according to the technical development in atrial anastomosis: the large anastomosis in which venous incision reached into at least one pulmonary vein beyond common pulmonary vein and the continuous running suture were used in 10 patients (group 1), the appropriate size of anastomosis in which venous incision limited within the common pulmonary vein and the continuous running suture used in 4 patients (group 2), and the appropriate size of anastomosis and the interrupted suture in 8 patients (group 3). PVOA were 3 (33%) in group 1, but 0 (0%) in group 2 and 3. Two late death occurred all in group 1 with PVOA. Cardiopulmonary bypass time and aortic clamp time in group 3 were 91 min and 74 min respectively, which did not become longer than those in both group 1 and group 2. Interrupted suture technique does not make operating time longer than continuous running suture one. PVOA is one of the important factors predicting late operative result.(ABSTRACT TRUNCATED AT 250 WORDS)     

Heterotopic heart transplantation: a radiographic review

Heterotopic heart transplantation can be performed in the presence of high pulmonary vascular resistance. The authors call attention to a rare, but potentially life-saving procedure.     

Intraocular pressure-dependent dynamic changes of optic disc cupping in adult glaucoma patients.

The authors performed a study of intraocular pressure-dependent changes in optic disc cupping in 17 adults with chronic open-angle glaucoma. Analyses with the Rodenstock Optic Nerve Head Analyzer were performed at baseline low intraocular pressure during therapy, after elevation of intraocular pressure (from therapeutic failure or noncompliance), and after reduction of intraocular pressure with successful therapy. Optic disc cupping increased significantly upon short-term increase of intraocular pressure from baseline of 20.4 +/- 2.5 mmHg to 31.1 +/- 5.9 mmHg. Optic disc cupping reverted to baseline after persistent intraocular pressure reduction to 19.3 +/- 4.8 mmHg. These data demonstrate intraocular pressure-dependent dynamic changes of optic disc cupping in patients with demonstrable glaucomatous optic nerve damage. They underscore the detrimental effect of elevated intraocular pressure and the beneficial effect of intraocular pressure reduction on optic disc cup changes.     

Respiratory symptoms and cigarette smoking in 3,197 pulmonologist-based asthmatic patients with a highly prevalent use of inhaled corticosteroid.

The relation between smoking and risk of asthma has been well-examined; however little attention has been paid to the correlation between smoking and asthma symptoms. The aims of this study were to examine respiratory symptoms in asthmatics with a highly prevalent use of inhaled corticosteroid (ICS) and to assess the effects of smoking and its cessation. A cross-sectional study of pulmonologist-based 3197 asthmatics (men 45.2%, ages 20-97) was performed using a questionnaire about smoking habits, the incidence and frequency of symptoms (sputum, cough and wheezing, night symptoms, and shortness of breath), physical activity interference, and medication. Although 81.4% of the patients used ICS according to the international guideline, 14.9% had activity interference, and daily symptoms remained in 43.3%. At the time of the questionnaire, 21.6% were current and 25.1% were ex-smokers. In multiple logistic regression analysis, the factors of significance (p < 0.0001) were (1) smoking; for all four symptoms, (2) age and duration of asthma; for shortness of breath. Current smokers were at a risk of sputum (age-adjusted odds ratio 2.32 [95% confidence interval 1.73-3.11]; 2.09 [1.57-2.79]), of cough and wheezing (2.38 [1.81-3.14]; 1.78 [1.35-2.36]), of night symptoms (1.95 [1.41-2.60]; 1.47 [1.09-1.98]), and of shortness of breath (1.70 [1.26-2.28]; 1.30 [0.97-1.75]) in men and women, respectively. These ratios in ex-smokers decreased to the level similar to nonsmokers. Although 81.4% of asthmatic patients used ICS, 43.3% complained of daily respiratory symptoms, especially sputum. It is suggested that the effects of ICS on asthma symptoms may be interfered with by smoking and therefore more emphasis should be placed on cessation of smoking.
