Measurements of Blood Pressure, Oedema and Proteinuria in a Pregnant Population of New Zealand

Summary: This is the first report of the largest study of blood pressure measurement in pregnancy in a New Zealand population using standardized definitions and methodology. Over 3,800 women who delivered in an 8-month period in the Wellington region were included in the study. Blood pressure measurement and the presence of oedema and proteinuria were recorded from booking until delivery and in the puerperium. Only 2.7% of women were unable to be contacted after delivery for details on outcomes. The results established normal ranges for blood pressure throughout pregnancy. The data show that Mood pressure greater than 140/90 until 35 weeks' gestation is outside 2 standard deviations at all gestations and justifies using these measurements as the definition of hypertension in pregnancy. The fall in blood pressure in the 2nd trimester was less than 1 mm Ffg per week in both the systolic and diastolic pressures. This fall was smaller than previously recorded in other studies. Gestational hypertension was the commonest blood pressure abnormality occurring in 15.2% of the population. This represented 69% of the pregnant women with a hypertensive disorder. The overall incidence of both gestational hypertension and preeclampsia was 18.5% which is higher than reported in other parts of the world. In this study obesity was significantly associated with hypertensive disorders in pregnancy. An arm circumference of >33 cm, one of the measurements of obesity, was found in 6.8% of the study population. Even after the effect of arm circumference was taken into account, hypertensive disorders were also more common in Pacific Island women. Ankle oedema was significantly associated with the development of both gestational hypertension and preeclampsia but the incidence of oedema was noted in only 11.9% of the subjects.     

Ketoprofen Versus Paracetamol in the Treatment of Acute Migraine

The efficacy and safety of ketoprofen and paracetamol were compared for the treatment of acute migraine in a randomized, double-blind study of 64 patients. Thirty-four patients received ketoprofen 100 mg intramuscularly, and 30 patients received paracetamol 500 mg intramuscularly. Partial or complete relief of pain and other symptoms was achieved 15 to 20 minutes after administration in the ketoprofen group and within 35 minutes in the paracetamol group. Complete relief of pain was achieved within 30 to 40 minutes after ketoprofen in 28 patients (82.5%) compared to 5 patients (17.5%) in the paracetamol group. Six of the patients treated with ketoprofen needed a second dose for complete relief of pain during the 4-hour follow-up period. Side effects were rare and minimal. Our findings suggest that ketoprofen produced statistically significant benefit in the treatment of acute migraine.     

Kardiale Manifestationen der HIV-Infektion

Zusammenfassung. Die Infektion mit dem humanen Immundefizienzvirus (HIV) betrifft nicht nur das Immunsystem des menschlichen Organismus, sondern schließt vielmehr eine Reihe weiterer Organsysteme mit ein. Es wird angenommen, dass bei 5-15% der HIV-positiven Patienten kardiale Manifestationen auftreten. Zu den häufigsten HIV-assoziierten kardialen Manifestationen gehören der Perikarderguss und die chronisch aktive, fokale oder diffuse Myokarditis. Endokardiale Manifestationen bei HIV-positiven Patienten treten in Form der infektiösen Endokarditis und der nichtbakteriellen thrombotischen Endokarditis auf. In der Regel weisen HIV-assoziierte kardiale Manifestationen einen langsam progredienten Krankheitsverlauf auf. Komplikationen sind Folge eines langfristig unentdeckten Fortschreitens der Erkrankung, aber auch schnell progredienter Verlaufsformen. Aufgrund der Vielzahl HIV-assoziierter kardialer Manifestationen und deren möglicher Komplikationen ist daher neben der Früherkennung ein effektives diagnostisches und therapeutisches Vorgehen erforderlich. Seit Einführung der Proteaseinhibitoren in den 90er Jahren und der Anwendung der hochaktiven antiretroviralen Kombinationstherapie (HAART) konnten sowohl Mortalität als auch Morbidität der HIV-Infektion deutlich gesenkt werden. Die Auswirkungen der HAART auf das kardiovaskuläre System sind bisher nur in Ansätzen bekannt. Als Nebenwirkungen wurden metabolische Veränderungen in Form von Hyperlipoproteinämie und Insulinresistenz bei einer Vielzahl HIV-positiver Patienten beobachtet. Es kann davon ausgegangen werden, dass durch den Anstieg der kardiovaskulären Risikofaktoren unter der HAART in den nächsten Jahren eine erhöhte Rate kardialer Erkrankungen bei HIV-positiven Patienten auftreten wird. In dem vorliegenden Übersichtsartikel wird ein Überblick über die häufigsten kardialen Erkrankungen bei HIV-Infektionen gegeben. Zusätzlich werden Vorschläge zu Diagnostik und Therapie unterbreitet und eine Einschätzung über Veränderungen der HIV-assoziierten kardialen Manifestationen nach Einführung der HAART vorgenommen. Abstract. The human immunodeficiency virus (HIV) does not only affect the immune system. Other organs including the cardiovascular system are influenced by the HIV as well. Most common HIV-associated cardiac manifestations are pericardial effusion and chronic active, focal or diffuse myocarditis. In addition to peri- and myocardial disease, endocardiac manifestations occur as infective endocarditis and nonbacterial thrombotic endocarditis in HIV-infected patients. Although most of the cardiac manifestations associated with HIV-infection exhibit a slow progression, rapid courses may lead to fatal complications. Early screening of HIV-infected patients will identify the potentially fatal complications of HIV disease and permit efficient treatment. The use of highly active antiretroviral therapy (HAART) significantly reduced the mortality and morbidity of HIV-infected patients. However, the impact that HAART will have on the incidence and prevalence of cardiac complications in HIV-infected patients is still unknown. It can be predicted, that the long-term viral infection and the increase of cardiovascular risk factors by HAART will probably lead to an increased prevalence of HIV-infected individuals with cardiac complications in the next decade. The present review describes the most frequent HIV-associated cardiac manifestations including diagnostic and therapeutic perspectives.
