Kartagener's syndrome in a woman with a normal ciliary structure and an intracranial meningioma.

Kartagener's syndrome is usually associated with ciliary abnormalities. We describe a case of Kartagener's syndrome observed in a woman with an intracranial meningioma and a normal axonemal structure. This finding confirms that ultrastructural defects of bronchial cilia are not always present in Kartagener's syndrome.

[Isradipine versus diltiazem in the treatment of stable effort angina pectoris: ergometric evaluation in a crossover double-blind study]. / Isradipina versus diltiazem nella terapia della angina stabile da sforzo: valutazione ergometrica in crossover doppio cieco.

OBJECTIVES: To evaluate the effects of isradipine (ISR) and diltiazem (DIL) on exercise tolerance and ischemic ST depression in patients with stable effort angina. METHODS: Fourteen out-patients, 9 males and 5 females, aged 46-65 years (mean +/- SD = 57 +/- 8), with ischemic heart disease and reproducible ST-segment depression on two consecutive exercise stress tests in baseline conditions, underwent a study consisting of 4 periods: 1 and 3 placebo, 2 and 4 at random ISR (5 mg b.i.d.) and DIL (120 mg b.i.d.). At the end of each period a multistage treadmill exercise stress test (Bruce protocol) was performed. RESULTS: Both drugs significantly (p < 0.001) increased ischemia time (IT) (0.1 mV ST depression) as compared to placebo, from 438 +/- 132 s. to 620 +/- 164 s. (ISR) and 583 +/- 147 s. (DIL) without statistical difference between two drugs (p = 0.2), and significantly reduced (p < 0.002) the maximal ST depression, from -0.20 +/- 0.11 mV to -0.07 +/- 0.07 mV (ISR) and -0.09 +/- 0.11 mV (DIL). At the IT, systolic blood pressure increased (p = 0.02), from 180 +/- 19 mm Hg to 187 +/- 15 mm Hg (ISR) and 191 +/- 15 mm Hg (DIL); similarly, heart rate increased from 133 +/- 24 bpm to 144 +/- 18 bpm (ISR: p = 0.002) and 140 +/- 17 bpm (DIL: p = NS). CONCLUSIONS: ISR and DIL, at the above dosage have showed an important and significant anti-ischemic effect (IT = +41.5% during ISR and +33.1% during DIL).

[An ergometric cross-over evaluation of the anti-ischemic efficacy of amlodipine and gallopamil in stable angina of effort]. / Valutazione ergometrica in cross-over dell'efficacia antischemica dell'amlodipina e del gallopamil nell'angina stabile da sforzo.

In the setting of stable effort angina a single-blind, randomized, cross-over study to evaluate the effects of gallopamil (GAL) and amlodipine (AML) on exercise tolerance and ischemic ST depression was conducted. Fifteen outpatients, 12 males and 3 females, aged 40-65 years (57 +/- 9), with documented coronary atherosclerosis and reproducible ST-segment depression on 2 consecutive baseline exercise stress tests, completed the study, which consisted of 4 periods: 1 and 3 placebo, 2 and 4 at random GAL (50 mg tid) and AML (10 mg/daily). At the end of each period a multistage treadmill exercise stress test (Bruce protocol) was performed. Both drugs significantly (p = 0.0001) increased the ischemia time (IT) (0.1 mV ST depression) as compared to placebo, from 416 +/- 165 s to 635 +/- 161 s (GAL) and 607 +/- 152 s (AML) with significant difference (p = 0.2) between the 2 drugs, and reduced significantly (p = 0.001) the maximal ST depression from -0.25 +/- 0.09 mV to -0.11 +/- 0.08 mV (GAL) and -0.12 +/- 0.09 mV (AML). At the IT, the systolic blood pressure increased from 178 +/- 23 mmHg to 185 +/- 20 mmHg (GAL) and remained unchanged during AML treatment (178 +/- 15 mmHg); similarly, the heart rate increased from 126 +/- 22 b/min to 139 +/- 21 b/min (GAL) and 138 +/- 19 b/min (AML). In conclusion, both GAL and AML showed a good anti-ischemic effect (IT = +52.6% during GAL and +45.9% during AML), even if GAL proved to be significantly more effective than AML.
