ObjectivesFacial lipoatrophy can be devastating for HIV-infected patients, with negative effects on self-esteem. In this study, we treated facial fat atrophy in the nasogenian area with hyaluronic acid (Restylane SubQ; Q-Med AB, Uppsala, Sweden). MethodsTwenty patients were included in the study. Treatment effects were evaluated at baseline, and at weeks 6, 24 and 52 using ultrasound, the Global Aesthetic Improvement Scale, the Visual Analogue Scale and the Rosenberg Self-Esteem Scale. ResultsMean (AE standard deviation) total cutaneous thickness increased from 6 AE 1 mm at baseline to 15 AE 3 mm at week 6 (Po0.001), and declined to 10 AE 2 mm at week 52 (Po0.001 vs baseline). The response rate (total cutaneous thickness 410 mm) was 100% at week 6, 85% at week 24 and 60% at week 52. At week 6, all of the patients classified their facial appearance as very much improved or moderately improved. They also reported increased satisfaction with their facial appearance and had higher self-esteem scores. At week 52, 15 of 19 patients still classified their facial appearance as very much improved or moderately improved, although the mean total cutaneous thickness had gradually declined. ConclusionsOur results indicate that Restylane SubQ is a useful and well-tolerated dermal filler for treating HIV-positive patients with facial lipoatrophy.
In contrast to the advanced transfusion medicine in developed nations, our findings highlight the persistent and urgent need for life-saving blood transfusions in especially young children and pregnant women in Africa. The results indicate that blood transfusion services adapted to local conditions may be a realistic solution for providing safe blood products in developing countries. Serious challenges, such as HIV transmission and sustainable organization of low-risk blood donations should be addressed to assure access to safe blood products.
ObjectivesFacial lipoatrophy can be a stigmatizing side effect of antiretroviral (AVR) treatment for HIV-infected patients. We sought to evaluate the long-term efficacy and safety of a new formulation of hyaluronic acid that can be injected in larger amounts and into deeper skin layers during 3 years of follow-up. Methods Twenty patients received injections of Restylane SubQ 2. Refill treatment was offered at 12 and 24 months. Treatment effects were evaluated using ultrasound, the Global Aesthetic Improvement Scale, visual analogue scale (VAS) and the Rosenberg self-esteem scale. ResultsSeventeen patients remained at 36 months. Mean (AE standard deviation) total cutaneous thickness increased from 6 AE 1 mm at baseline to 12 AE 1 mm (Po0.001) at 36 months. Response rate (total cutaneous thickness 410 mm) was 70%. Fifteen patients classified their facial appearance as very much or moderately improved. VAS increased from 39 AE 25 to 70 AE 20 (Po0.05) and higher self-esteem scores were reported. Local swelling and tenderness after treatment was common. Persistent papules found in several patients after treatment were removed effectively with hyaluronidase injections. Three patients, treated only at baseline, still had higher total cutaneous thickness scores at 36 months. ConclusionsOur results indicate that a large particle hyaluronic acid formulation is a durable and well-tolerated dermal filler for treating HIV-positive patients with facial lipoatrophy. IntroductionLipoatrophy is a particularly distressing aspect of lipodystrophy evident in HIV-positive patients on antiretroviral therapy (ART). Facial lipoatrophy can severely affect patients' quality of life and may contribute to reduced antiretroviral (AVR) adherence [1]. Furthermore, the stigmatization affected patients may encounter as a result of facial lipoatrophy can be detrimental for self-esteem [2]. Treatment strategies include switching AVR regimens, prescription of medication, insertion of surgical implants and injection of dermal fillers.While there is evidence that the use of new nonthymidine nucleoside reverse transcriptase inhibitors can prevent the development of lipoatrophy, switching medications, after lipoatrophy has progressed, offers only limited benefit [3,4]. A follow-up study of the Oslo HIV Cohort Study 2000 found that facial atrophy was less reversible than fat atrophy of the extremities [5]. Medications such as pioglitazone [6], uridine [7] and pravastatin [8] have been shown to have some effect on limb lipoatrophy in HIV-infected patients; however, the mechanisms by which they work and their potential side effects are not well documented.In the absence of a therapeutic intervention to reverse lipoatrophy, injection of soft-tissue fillers appears to be the simplest way to correct facial lipoatrophy. Many soft-tissue fillers, both biodegradable and permanent, have been studied in HIV facial lipoatrophy, however, long-term clinical safety and efficacy data are lacking. Biodegradable fillers have a good safety profile, but treatment with s...
Background Less than 50% of stroke patients in Norway reach hospital within 4 h of symptom onset. Early prehospital identification of stroke and triage to the right level of care may result in more patients receiving acute treatment. Quality of communication between paramedics and the stroke centre directly affects prehospital on-scene time, emphasising this as a key factor to reduce prehospital delay. Prehospital stroke scales are developed for quick and easy identification of stroke, but have poor sensitivity and specificity compared to an in-hospital assessment with the National Institutes of Health Stroke Scale (NIHSS). The aim of the Paramedic Norwegian Acute Stroke Prehospital Project (ParaNASPP) is to assess whether a structured learning program, prehospital NIHSS and a mobile application facilitating communication with the stroke physician may improve triage of acute stroke patients. Methods A stepped wedge cluster randomised controlled intervention design will be used in this trial in Oslo, Norway. Paramedics at five ambulance stations will enrol adult patients with suspected stroke within 24 h of symptom onset. All paramedics will begin in a control phase with standard procedures. Through an e-learning program and practical training, a random and sequential switch to the intervention phase takes place. A mobile application for NIHSS scoring, including vital patient information for treatment decisions, transferring data from paramedics to the on-call stroke physician at the Stroke Unit at Oslo University Hospital, will be provided for the intervention. The primary outcome measure is positive predictive value (PPV) for prehospital identification of patients with acute stroke defined as the proportion of patients accepted for stroke evaluation and discharged with a final stroke diagnosis. One thousand three hundred patients provide a 50% surplus to the 808 patients needed for 80% power to detect a 10% increase in PPV. Discussion Structured and digital communication using a common scale like NIHSS may result in increased probability for better identification of stroke patients and less stroke mimics delivered to a stroke team for acute diagnostics and treatment in our population.
