ABSTRACT

Kohl is a traditional cosmetic widely used in Asia and Africa. In recent years, demand for kohl-based eyelids and lipsticks has increased in Europe, linked to migratory phenomena of populations from these continents. Although the European legislation prohibits the use of heavy metals in cosmetics due to the harmful effects to human health, particularly to pregnant women and children, these elements are still present in certain products. The European Union recommended levels are Pb < 20 ppm, As < 5 ppm, Cd < 5 ppm, Sb < 100 ppm, and Ni < 200 ppm. In Germany, levels are more restrictive: Pb < 2 ppm, As < 0.5 ppm, Cd < 0.1 ppm, Sb < 0.5 ppm, and Ni < 10 ppm. Here, we analyzed 12 kohl-based cosmetics in different presentations (powder, paste, and pencil) that were purchased in Spanish and German local shops. An inductively coupled plasma optical emission spectrophotometer was used to identify toxic elements and heavy metals. Levels of Pb ranged between 1.7 and 410,000 ppm in six of the study samples, four of which had levels above the recommended limit of at least two heavy metals. Arsenic (a carcinogenic element) values were within the range allowed by the EU in only 58% of the studied samples. Moreover, two products doubled this limit, reaching levels of 9.2 and 12.6 ppm. In one of the products, cadmium, related to toxic keratitis, was four times higher (20.7 ppm) than that allowed, while in two other products, these limits were doubled (11.8 and 12.7 ppm). Our results indicate the need to supervise the manufacture of kohl-based traditional products and the analysis of their composition prior distribution in European countries.

ABSTRACT

Los adenomas hipofisarios son tumores infrecuentes de diagnóstico complejo, cuya heterogeneidad y baja incidencia dificultan estudios a gran escala. El Registro Molecular de Adenomas Hipofisarios (REMAH) nació en 2008 en el seno de la Sociedad Andaluza de Endocrinología y Nutrición (SAEN), como estrategia de cooperación clínico-básica y multicéntrica, para mejorar el diagnóstico y tratamiento de tumores hipofisarios mediante la combinación de información clínica, anatomopatológica y molecular. En 2010, la Sociedad Española de Endocrinología y Nutrición (SEEN) lo extendió a nivel nacional, estableciendo 6 nodos con protocolos y métodos comunes de recogida de muestras y datos clínicos, análisis molecular y anotación en un mismo registro (www.remahnacional.com). El registro combina datos clínicos con el fenotipado molecular del adenoma intervenido, mediante PCR cuantitativa en tiempo real de la expresión de 26 genes: hormonas hipofisarias (GH-PRL-LH-FSH-PRL-ACTH-CGA), receptores (somatostatina, dopamina, GHRH, GnRH, CRH, arginina-vasopresina, ghrelina), otros marcadores (Ki67, PTTG1) y genes de control. Hasta 2015 se ha obtenido información molecular de 704 adenomas, de los 1.179 pacientes registrados. Esta estrategia permite abordar análisis comparativos y relacionales entre el perfil molecular de los distintos tipos de adenomas y el fenotipo clínico del paciente, lo que puede ofrecer un mejor conocimiento de la enfermedad y, potencialmente, ayudar en la selección del tratamiento. El REMAH constituye una red única, multicéntrica e interdisciplinar, cimentada en una base de datos compartida, que aporta un enfoque traslacional de gran proyección potencial para el manejo de los adenomas hipofisarios y abre el camino para estudios conjuntos clínico-básicos innovadores con un elevado número de pacientes (AU)

ABSTRACT

BACKGROUND AND OBJECTIVES: The reported efficacy of treatments for acromegaly varies depending on reference centers and national registries. The aim of this study was to describe clinical management of this disease and to assess the efficacy of treatments used in standard clinical practice. MATERIAL AND METHODS: An epidemiological, observational, longitudinal, multicenter study was performed in adult patients with newly diagnosed acromegaly (n = 74) seen by 38 Spanish endocrinologists who collected during routine clinic visits data on disease treatment and control during 2 years of follow-up. RESULTS: Pituitary surgery and treatment with somatostatin analogs were the first choice therapies in 76% and 24% of patients respectively, with no differences related to tumor size. Surgery achieved disease control in 27% of operated patients. After surgery failure, the preferred therapeutic option were somatostatin analogs, which normalized insulin-like growth factor-1(IGF-I) in 52% of patients and achieved disease control criteria in more than 40% of patients. At the end of follow-up, normal IGF-I levels were found in 63% and 53% of patients with microadenomas and macroadenomas respectively. Only 19% of patients with macroadenoma met disease control criteria without requiring drug treatment, which was required by 85% of them at some time during follow-up. CONCLUSIONS: Surgery is the preferred initial treatment for patients with acromegaly, regardless of tumor size. Treatment efficacy in actual clinical practice is far from the success rates reported by reference centers.

ABSTRACT

BACKGROUND: In this specifically designed, prospective study, the authors addressed the predictive value of circulating levels of the extracellular domain (ECD) of HER2 in patients with metastatic breast cancer who were treated with letrozole. METHODS: Two hundred twenty-six patients with hormone receptor-positive, metastatic breast cancer received letrozole (2.5 mg daily) until they developed either disease progression or unacceptable toxicity. Efficacy was measured primarily as the time to progression (TTP) and, secondarily, as the objective response rate (ORR) and overall survival. HER2 ECD levels were determined by using a sandwich enzyme HER2/neu immunoassay before letrozole treatment was initiated. Positive HER2 ECD status was correlated with treatment efficacy. RESULTS: Forty-two patients (19%) had elevated HER2 ECD levels, which were associated with primary tumor HER2 expression (P < .001) but not with age, performance status, location, or number of metastatic sites. The median TTP was significantly shorter among patients who had elevated HER2 ECD compared with the median TTP among patients who had normal levels (4 months vs 14 months; P = .0004), and the ORR was lower in the group with elevated HER2 ECD levels (14% vs 30%; P < .036). Overall survival was significantly shorter among patients with elevated serum HER-2 ECD (P < .0005). CONCLUSIONS: Elevated HER2 ECD concentrations predicted poorer outcomes in postmenopausal women with metastatic hormone receptor-positive breast cancer who were treated with aromatase inhibitors like letrozole.

ABSTRACT

OBJECTIVE: To undertake a multicentre epidemiological study reflecting acromegaly in Spain. DESIGN: Voluntary reporting of data on patients with acromegaly to an online database, by the managing physician. METHODS: Data on demographics, diagnosis, estimated date of initial symptoms and diagnosis, pituitary imaging, visual fields, GH and IGF-I concentrations (requested locally), medical, radiotherapy and neurosurgical treatments, morbidity and mortality were collected. RESULTS: Data were included for 1219 patients (60.8% women) with a mean age at diagnosis of 45 years (s.d. 14 years). Reporting was maximal in 1997 (2.1 cases per million inhabitants (c.p.m.) per year); prevalence was globally 36 c.p.m., but varied between 15.7 and 75.8 c.p.m. in different regions. Of 1196 pituitary tumours, most were macroadenomas (73%); 81% of these patients underwent surgery, 45% received radiotherapy and 65% were given medical treatment (somatostatin analogues in 68.3% and dopamine agonists in 31.4%). Cures (GH values (basal or after an oral glucose tolerance test) <2 ng/ml, normal IGF-I, or both) were observed in 40.3% after surgery and 28.2% after radiotherapy. Hypertension (39.1%), diabetes mellitus (37.6%), hypopituitarism (25.7%), goitre (22.4%), carpal tunnel syndrome (18.7%) and sleep apnoea (13.2%) were reported as most frequent morbidities; 6.8% of the patients had cancer (breast in 3.1% of the women and colon in 1.2% of the cohort). Fifty-six patients died at a mean age of 60 years (s.d. 14 years), most commonly of a cardiovascular cause (39.4%); mortality was greater in patients given radiotherapy (hazard ratio 2.29; 95% confidence interval 1.03 to 5.08; P=0.026), and in those in whom GH and IGF-I concentrations were never normal (P<0.001). CONCLUSIONS: This acromegaly registry offers a realistic overview of the epidemiological characteristics, treatment outcome and morbidity of acromegaly in Spain. As active disease and treatment with radiotherapy are associated with an increase in mortality, efforts to control the disease early are desirable.
