Twelve patients with peripheral arterial occlusive disease were evaluated prospectively in an effort to further investigate the etiology of pedal and lower leg edema that occurs following revascularization (e.g., aorto-iliac or femoropopliteal bypass). Serum total protein, albumin, blood urea nitrogen, and creatinine levels were measured (in addition to peripheral venous pressure), and lymphoscintigraphy of the lower leg was performed. These parameters were assessed just prior to surgery, four weeks postoperatively, and again at follow-up. The serum levels obtained four weeks after surgery and on subsequent follow-ups were significantly higher than the preoperative values. Preoperative peripheral venous pressure was not significantly different from that obtained after surgery. There was no correlation between these pressure measurements and the degree of edema (Grades I to IV correspond to increasing degrees of severity). For both the supine and upright positions, lymphoscintigraphic counts in the inguinal region were significantly higher after surgery. However, the relative increase was dependent upon the severity of edema. The postoperative lymphoscintigraphic count in the upright position was 77 +/- 33 CPS in patients with Grades I and II edema (n = 6) and 20.6 +/- 16.2 CPS in patients with Grades III and IV edema (n = 10) (p less than 0.01). Thus, a lesser degree of postoperative pedal and lower leg edema was associated with higher lymphoscintigraphic counts. We conclude that major contributors to the development of lower extremity edema following arterial reconstruction are failed capillary hydrostatic pressure and interrupted lymphatic drainage.

The acute hypotensive effect of nifedipine was evaluated, and the possibility of its long-term use in hypertensives over 60 years of age was studied. Sublingual nifedipine in a dose of 20 mg was given to 28 patients, mean age 73.1 yrs, and blood pressure, heart rate, and plasma drug concentration were monitored at 15 min, and every 30 min thereafter for 3 hrs. Systolic and diastolic blood pressure decreased at 15 min by 22.1 and 7.0 mmHg, respectively, reaching a maximal decrease two hours after drug administration. The decrease in blood pressure level did not correlate with nifedipine plasma concentration, but only with the initial systolic blood pressure. Long-term treatment with nifedipine was initiated in 60 patients, with 45 patients completing the study. Mean age was 66.2 years. An initial dose of 30 mg daily had to be increased to 60-80 mg in one-third of the patients. Monotherapy was not satisfactory in some patients. Blood pressure gradually decreased from 173/99 to 148/85 mmHg at three months, and to 141/84 mmHg at six months. Drug tolerance was fairly good. Nifedipine was withdrawn due to a considerable increase in heart rate in three patients and skin allergy in one. The most frequent adverse symptoms were: rash, headache, and leg oedema. Laboratory tests revealed no changes in urea and creatinine, and an increase in fasting glycaemia. Lipid parameters did not change significantly. These data proved that a single dose of 20 mg of nifedipine produced therapeutic plasma concentration of the drug and good hypotensive effect, positively correlating with initial systolic blood pressure.(ABSTRACT TRUNCATED AT 250 WORDS)

Of a total of 780 patients with abdominal aortic aneurysms, 37 patients (4.7%) had inflammatory aneurysms. Presenting symptoms included back and abdominal pain (76%), leg edema, melena, uremia, claudication and pancreatitis. Mean erythrocyte sedimentation rate was 45 mm/hr. Weight loss and anorexia were common. Elevated urea and creatinine were seen on 11 patients, nine of whom had obstructive uropathy. Average aneurysm size was 9.3 cm. Thirty-six patients were treated surgically and one was observed. Involvement of the suprarenal (nine cases) or thoracic (three cases) aorta was common. Elective operations included resection and grafting in 21 patients and axillofemoral bypass in four patients. Patients with ureteral entrapment underwent simultaneous ureterolysis. Among the elective operations four deaths were noted (15%). Ten emergency operations were done for posterior rupture (four cases), aortoduodenal fistula (one case), inferior vena cava obstruction or fistula (two cases), hemorrhage into the aneurysmal wall (two cases), or presumed rupture (one case). There were seven deaths (70%) in this group. The operation of choice for inflammatory aneurysm is a bifurcation graft combined with ureterolysis.

We report the case of a patient with an idiopathic syndrome of inappropriate secretion of ADH for more than 6 years. Water restriction was effective only during hospital care but was socially difficult to maintain at home, so that the patient presented frequent symptoms of water intoxication. Normal natremia was also obtained with a high salt intake (9 g/day) but this induced leg edema mild dyspnea and gastric intolerance. The patient was however successfully treated for more than 5 years without any side effects with oral urea (30 g/day) allowing her a normal fluid intake (1-1.5 liters/day). Oral urea, even during long periods, is a safe and effective therapeutic approach for patients with chronic SIADH which is not controlled by water restriction alone.

A 58-year-old man ingested an herbal preparation of Ajuga nipponesis Makino, as recommended in folk medicine for the treatment of hepatoma. He developed profound gastrointestinal upset immediately, and decreasing urine output and bilateral leg edema over the following 2 days. Notable laboratory findings included elevated levels of blood urea nitrogen, creatine, bilirubin, and hepatic transaminases. Deterioration of renal function was noted during hospitalization and he died 11 days after ingesting the herbal preparation. Two other healthy individuals also consumed the same herbal preparation at the same time but developed only vomiting and diarrhea. One or more of the four major components of Ajuga nipponesis Makino may be responsible for the renal toxicity found in our patient.
