Vascular Compromise from Soft Tissue Augmentation: Experience with 12 Cases and Recommendations for Optimal Outcomes

The popularity of soft tissue fillers is, in part, due to their favorable side-effect profile. However, serious complications can occur. The authors describe their extensive clinical experience with soft-tissue augmentation and the rare complication of vascular compromise, which can lead to necrosis and scarring. Over a 10-year period between January 2003 and January 2013, the authors observed a total of 12 cases of vascular compromise. Eight patients in their clinical practice showed evidence of vascular compromise out of a total of 14,355 filler injections (0.05%). In addition, four patients treated with an experimental particulate filler had vascular complications. All cases were examined for filler type, location of complication, risk factors, treatment, and outcomes. Although treatment plans differed for each patient in their series, all cases of vascular compromise resolved fully. The authors believe that an office-based protocol for both immediate and ongoing care—including a thorough individualized assessment and treatment plan for each patient—is critical to timely and effective resolution of side effects. They propose key recommendations for the prevention and management of vascular compromise to improve patient outcomes and reduce the risk of permanent complications.Injectable fillers have become an integral part of aesthetic medicine for patients who want noninvasive rejuvenation. They are used to restore volume and to smooth and efface superficial wrinkles and deep folds of the face, among other indications. Widespread use began in the 1980s with the advent of bovine collagen. Since then, use has surged so that soft tissue augmentation is the second most popular nonsurgical aesthetic procedure in North America to botulinum toxin.1 In 2007, more than 1.5 million soft tissue filler procedures were performed in the United States, with hyaluronic acid (HA) being the most frequently used.2 As of 2010, more than 200 types of fillers were available for soft tissue augmentation worldwide.1The popularity of soft tissue fillers is in part due to their favorable side-effect profile. Adverse effects from soft tissue filler injection are generally mild and self-limited. However, there are some well-documented serious complications. The most feared and potentially serious complications are vascular in nature. Collectively referred to as vascular compromise, these complications include partial or complete interruption of vascular supply by extravascular compression, or a complete occlusion of vascular supply from intravascular injection. Subsequent necrosis and scarring are potentially permanent sequelae.2-4In the authors’ clinical practice, 14,355 filler injections were performed between January 2003, when they first instituted their computer database, and January 2013. Fillers that are used in their office include hyaluronic acid (HA) (Juv''derm Ultra, Ultra plus, Voluma [Allergan, Irvine, California] and Restylane [Medicis Aesthetics Inc., Scottsdale, Arizona]); poly-L-lactic acid (Sculptra, Sanofi-Aventis, Bridgewater, New Jersey); calcium hydroxylapatite (Radiesse, Merz USA, Greensboro, North Carolina); silicone oil; and collagen (Evolence Breeze, Ortho Dermatologics, Skillman, New Jersey). During this 10-year period, a total of 12 cases of vascular compromise were observed and managed, eight of which occurred in the authors’ clinical practice and four in their clinical trials practice. Those cases that developed vascular compromise after soft tissue augmentation are reviewed and treatment discussed (Appendix 1).Over a 10-year period between January 2003 and January 2013, eight patients in the authors'' clinical practice showed evidence of vascular compromise out of a total of 14,355 filler injections (0.05%). They observed four cases after injection with calcium hydroxylapatite (CaHA) (out of 1,482 total injections; 0.27%), four cases after injection with volumizing monophasic HA (Juvéderm Voluma) (out of 4,321 total injections; 0.09%), and one case resulting from treatment with biphasic HA (Restylane) (out of 3,348 injections; 0.03%). One patient was treated with both CaHA and volumizing monophasic HA, and is counted in both groups (

Clinical Manifestation and Diagnostic Process of Celiac Disease in Poland—Comparison of Pediatric and Adult Patients in Retrospective Study

The diagnosis of celiac disease (CD) may be delayed due to non-specific clinical symptoms. The aim of the study was to evaluate the clinical manifestation and diagnostic process of CD in Polish children and adults. Methods: The members of the Polish Coeliac Society (n = 2500) were asked to complete a questionnaire on socio-demographic factors, clinical and diagnostic aspects of CD. The analysis was based on 796 responses from patients with confirmed CD diagnosis, and included 224 (28.1%) children and 572 (71.9%) adults. Results: The mean duration of symptoms prior to CD diagnosis in children was significantly shorter than in adults (p < 0.001), and amounted to 3.1 and 9 years respectively. The most frequent symptoms before CD diagnosis were abdominal pain and bloating in children (70.4%), and chronic fatigue in adults (74.5%). Although almost all CD patients claimed to strictly avoid gluten after CD diagnosis, symptoms were still present in the majority of these respondents. No comorbid diseases were reported by 29.8% of children and by 11.7% of adults (p < 0.001). Conclusions: the results indicate that CD diagnosis is delayed in Poland, especially in adults, and clinicians should be aware of the diversity in CD presentation.     

Randomised controlled trial of intermittent vs continuous energy restriction during chemotherapy for early breast cancer

Background Excess adiposity at diagnosis and weight gain during chemotherapy is associated with tumour recurrence and chemotherapy toxicity. We assessed the efficacy of intermittent energy restriction (IER) vs continuous energy restriction (CER) for weight control and toxicity reduction during chemotherapy.Methods One hundred and seventy-two women were randomised to follow IER or CER throughout adjuvant/neoadjuvant chemotherapy. Primary endpoints were weight and body fat change. Secondary endpoints included chemotherapy toxicity, cardiovascular risk markers, and correlative markers of metabolism, inflammation and oxidative stress.Results Primary analyses showed non-significant reductions in weight (−1.1 (−2.4 to +0.2) kg, p = 0.11) and body fat (−1.0 (−2.1 to +0.1) kg, p = 0.086) in IER compared with CER. Predefined secondary analyses adjusted for body water showed significantly greater reductions in weight (−1.4 (−2.5 to −0.2) kg, p = 0.024) and body fat (−1.1 (−2.1 to −0.2) kg, p = 0.046) in IER compared with CER. Incidence of grade 3/4 toxicities were comparable overall (IER 31.0 vs CER 36.5%, p = 0.45) with a trend to fewer grade 3/4 toxicities with IER (18%) vs CER (31%) during cycles 4–6 of primarily taxane therapy (p = 0.063).Conclusions IER is feasible during chemotherapy. The potential efficacy for weight control and reducing toxicity needs to be tested in future larger trials.Clinical trial registration ISRCTN04156504.Subject terms: Randomized controlled trials, Breast cancer, Nutrition, Weight management, Breast cancer     

Colorectal cancer in the young patient

Colorectal cancer is the second most common cause of death from cancer in the UK. It is estimated that between 2 to 3 per cent of colorectal cancer occurs in patients younger than the age of 40 years. It remains unclear from the literature whether this group of patients has a worse prognosis from colorectal cancer than the population as a whole. There are no large series that report a 10-year survival in young patients diagnosed with colorectal cancer. The authors' objective was to assess patients diagnosed with colorectal cancer younger than the age of 40 years to determine whether the 5- and 10-year survival rates in a tertiary referral center compares favorably with survival rates obtained at other centers and the population as a whole. A retrospective observational study was conducted and an analysis of the patient's notes was made, specifically looking at age at diagnosis, nature and duration of symptoms, predisposing risk factors for colorectal cancer, the site within the bowel of the colorectal cancer, the type of curative resection performed, Dukes' stage, and details of 5- and 10-year follow-up to assess survival. Forty-nine patients age 40 years or younger received treatment for colorectal cancer at St. Mark's Hospital from 1982 to 1992. The overall 5- and 10-year survival was 58 per cent and 46 per cent respectively. The study provides more evidence to support the fact that young patients with colorectal cancer seem to present with more advanced disease. Despite this, the overall 5-year relative survival rate is comparable if not better than other studies, supporting recent evidence that the prognosis in this group of patients is no worse than for colorectal cancer in the population as a whole.     

Serum markers detect the presence of liver fibrosis: a cohort study

BACKGROUND & AIMS: Histologic examination of a liver biopsy specimen is regarded as the reference standard for detecting liver fibrosis. Biopsy can be painful and hazardous, and assessment is subjective and prone to sampling error. We developed a panel of sensitive automated immunoassays to detect matrix constituents and mediators of matrix remodeling in serum to evaluate their performance in the detection of liver fibrosis. METHODS: In an international multicenter cohort study, serum levels of 9 surrogate markers of liver fibrosis were compared with fibrosis stage in liver biopsy specimens obtained from 1021 subjects with chronic liver disease. Discriminant analysis of a test set of samples was used to identify an algorithm combining age, hyaluronic acid, amino-terminal propeptide of type III collagen, and tissue inhibitor of matrix metalloproteinase 1 that was subsequently evaluated using a validation set of biopsy specimens and serum samples. RESULTS: The algorithm detected fibrosis (sensitivity, 90%) and accurately detected the absence of fibrosis (negative predictive value for significant fibrosis, 92%; area under the curve of a receiver operating characteristic plot, .804; standard error, .02; P < .0001; 95% confidence interval, .758-.851). Performance was excellent for alcoholic liver disease and nonalcoholic fatty liver disease. The algorithm performed equally well in comparison with each of the pathologists. In contrast, pathologists' agreement over histologic scores ranged from very good to moderate (kappa = .97-.46). CONCLUSIONS: Assessment of liver fibrosis with multiple serum markers used in combination is sensitive, specific, and reproducible, suggesting they may be used in conjunction with liver biopsy to assess a range of chronic liver diseases.
