RESUMO

Drug-induced lupus erythematosus differs in its manifestation from drug-induced vasculitis. The former is associated with characteristic symptoms that improve following discontinuation, whereas the latter is predominantly an antineutrophil cytoplasmic antibody (ANCA) positive small vessel vasculitis involving the kidneys, skin, and lungs. We present a case of advanced disease in an elderly Caucasian woman requiring corticosteroids, and immunosuppressive therapy, who was on hydralazine for >2 years.

RESUMO

BACKGROUND AND PURPOSE: Enhanced external counter pulsation (EECP) is used to treat angina. With sustained treatment this increases collateral circulation to the coronary arteries as well as to the body as a whole. We found some patients who underwent EECP for angina or congestive heart failure who also coincidentally had severe Restless Legs Syndrome (RLS). Case reports are presented. PATIENTS AND METHODS: Six patients with RLS (1F, 5M, ages 55-80) underwent EECP treatment. All patients were given the International RLS Study Group rating scale for RLS (the IRLS) before and immediately after 35 days of EECP treatment. RESULTS: The average IRLS rating scale score of the six patients before treatment was 28.8 (range 23-35), which indicates frequent and moderate to very severe RLS. After 35 days of EECP treatment the IRLS score was 6 (P<0.03), which indicates clinically insignificant RLS. Long-term follow-up in three patients indicates sustained improvement in all three at 3-6 months after EECP was completed (IRLS score 28.3-3.33). Further follow-up in four patients showed sustained improvement in two patients 1 year after EECP was completed. CONCLUSION: EECP improves RLS symptoms significantly and could be considered as an adjunct treatment for patients with RLS. In some cases, the improvement lasts for months after the course of treatment. In this way EECP is unique and unlike pharmacotherapy which requires continuous daily treatment. Furthermore, our results suggest that decreases in vascular flow influence the peripheral or central nervous system leading to the sensory symptoms of RLS. A larger number of patients studied under blinded conditions is needed to draw further conclusions.

RESUMO

STUDY OBJECTIVES: Growing pains may be an important clue to the diagnosis of childhood restless legs syndrome (RLS). However, there are no previous studies to determine whether a subpopulation of children with growing pains meet the diagnostic criteria for RLS. The purpose of this study is to determine if some children with growing pains meet diagnostic criteria for RLS and to compare the polysomnographic characteristics of these children to controls. DESIGN/PARTICIPANTS/MEASUREMENTS: Eleven children from a pediatric neurology clinic with an emphasis on attention-deficit/hyperactivity disorder (ADHD) and with a diagnosis of growing pains were referred. They were interviewed with the parent to determine if their symptoms of growing pains met criteria for definite RLS. Those who met clinical criteria for RLS underwent polysomnography, and the results of their polysomnographic studies were compared to those of a control group (10 children, mean age 9.7 years). SETTING: Academic medical center. RESULTS: Ten (mean age 10.4 years) of the 11 children with growing pains met clinical criteria for RLS. In 4 of 8 families of these 10 children, 1 parent had RLS. Six of the 10 children had ADHD. There were no differences in the polysomnographic findings between the growing-pain and control groups, and none of the children with RLS had what is considered to be a clinically significant number of periodic limb movements of sleep. There were no differences in the polysomnographic findings between the "growing-pain ADHD" and "growing-pain non-ADHD" subgroups. The growing pains were severe enough for the patients and family to ask for treatment in 4 cases, and carbidopa/levodopa was utilized. CONCLUSIONS: Some children diagnosed with growing pains meet diagnostic criteria for RLS, and a family history of RLS is common in these children. In some cases symptoms are severe enough to warrant treatment.

RESUMO

OBJECTIVE: To evaluate the effect of an intravenously administered synthetic epoprostenol analog, iloprost, in nonocclusive acute mesenteric ischemia induced by cardiac tamponade. DESIGN: Prospective, randomized, controlled experimental study. SETTING: Animal research laboratory at a university medical center. SUBJECTS: Ten Yorkshire pigs (weight range, 20-25 kg). INTERVENTIONS: Nonocclusive acute mesenteric ischemia was induced by pericardial tamponade. Pigs were randomized to receive either a low-dose, continuous intravenous infusion of iloprost (0.075 microg/kg/min) or an equivalent volume of normal saline to serve as the control. Infusion of iloprost or saline was continued after pericardial tamponade was reversed. METHODS: Ten anesthetized and ventilated pigs underwent laparotomy and thoracotomy. A pulmonary artery catheter was inserted, a magnetic flow probe was positioned around the superior mesenteric artery (SMA), and cannulation of the pericardial space was performed. Pericardial tamponade was induced by injecting 5% dextrose in water into the pericardial space until blood flow in the superior mesenteric artery decreased to half of baseline. After 60 mins, animals received either a continuous intravenous infusion of iloprost at 0.075 microg/kg/min (n = 6) or an equal volume of normal saline (n = 4) for 60 mins. Pericardial fluid was then removed, and iloprost or normal saline infusion was continued for another 60 mins. MEASUREMENTS: Heart rate, blood pressure, cardiac output, oxygen delivery, oxygen consumption, SMA blood flow, ileal Pco2, ileal intramucosal pH, and serum lactate levels of mixed venous blood and mesenteric venous blood were recorded at baseline, after pericardial tamponade was induced, during the iloprost or normal saline infusion with pericardial tamponade, and after removal of pericardial fluid (reperfusion period). RESULTS: Iloprost infusion increased SMA blood flow by 60% in this model of nonocclusive mesenteric ischemia (from 168 +/- 41 to 269 +/- 76 mL/min; p <.05). The effect of iloprost infusion was more prominent after the tamponade (422 +/- 87 mL/min in the iloprost group vs. 232 +/- 111 mL/min in the control group; p <.05). Increased mesenteric perfusion decreased intestinal mucosal hypercarbia, leading to improvement of intramucosal pH.
