Kasabach-Merritt syndrome arising from a vascular fistula.

A 58-year-old woman presented with gum bleeding, hematuria, and cutaneous ecchymoses. Left hip replacement had been performed five years prior. The overall findings of our work-up were consistent with ongoing DIC triggered by the presence of an arterio-venous left femoral fistula.

Fatal neuroleptic malignant syndrome in a previously long-term user of clozapine following its reintroduction in combination with paroxetine.

A 77-year-old patient with initial behavioral and psychological symptoms of dementia was treated with clozapine (50 mg/daily). Since no clinical benefit was apparent, clozapine was discontinued after six weeks and the patient started on paroxetine (20 mg/daily). After three weeks on paroxetine, he was given another trial of clozapine at a starting dosage of 25 mg/daily.

The comprehensive geriatric assessment: when, where, how.

Cancer is increasingly a disease of the aged, a segment of the population that is the fastest growing. Often, cancer adds on to the progressive deterioration of normal aging and to the impairment associated with the presence of multiple concomitant medical problems. Thus, the likelihood that cancer leads to disability is much greater among older patients than younger ones.

Amlodipine in ambulatory hypertensive patients: humoral and haemodynamic effects.

In order to evaluate the mid-term effects of amlodipine, a 1,4-dihydropyridine calcium antagonist, as well as its effects on the renin-angiotensin-aldosterone system (RAAS), on water and electrolyte balance, on urinary excretion of albumin (UAE) and on lipid metabolism, thirteen hypertensive patients (2 M, 11 F, mean age 54 years) were studied in the course of 24 weeks of therapy with amlodipine at 5-10 mg/day. Pre-therapy and periodically during therapy, the systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR) were recorded in the sitting orthostatic positions (2 measurements). Laboratory tests were performed at times O and at 24 wks with the patients fasting for at least 12 h in the recumbent position.

[The behavior of serum angiotensin-converting enzyme in normotensive subjects, in subjects with essential hypertension and in subjects with primary hyperaldosteronism on the orthostatic test].

The results of this study demonstrate that only in healthy normotensive subjects during extended orthostatism that the renin-angiotensin-aldosterone system remains integral and is characterized by a significant increase in serum angiotensin-converting enzyme (SACE), plasma renin activity (PRA) and plasma aldosterone (PA). SACE modification do not seems to directly follow that of PRA (as shown by the absence of a direct correlation between SACE and PRA). In essential hypertension, the behavior of SACE seems to change, without demonstrating a significant increase in the mean levels of this enzyme.

[Serum activity of angiotensin-converting enzyme and osteocalcin levels in hyperthyroidism].

This study was carried out in order to investigate serum changes of osteocalcin (BGP) and angiotensin converting enzyme (SACE) activity in a group of patients with hyperthyroidism. We studied 20 hyperthyroid patients (F 14, M 6; age mean 37.5 +/- 16.
