Adenoma adrenal como etiología de síndrome de Cushing: veinte años de experiencia en un centro mexicano de tercer nivel

IntroductionCushing's syndrome (CS) includes a wide range of clinical and laboratory abnormalities and is the final outcome of chronic glucocorticoid exposure. Adrenal adenomas are an uncommon cause of adult CS.ObjectiveTo describe the characteristics and outcome of patients with CS caused by adrenal adenomas in a referral center.MethodsWe performed a retrospective cross-sectional observational study of patients with a diagnosis of CS caused by adrenal adenomas managed in our center over a 20-year period. Our clinical experience in the diagnosis and treatment of this entity was analyzed.ResultsThere were a total of 20 patients, 19 women and one man. The mean age was 25.9 years (14 to 52). The most frequently recorded clinical data were hirsutism and moon face. The mean morning cortisol level was 26.9±10.7 mcg/dl, the mean afternoon level was 24.4±8.5 mcg/dl and the mean corticotropin (ACTH) concentration was 24±19.4 pg/ml. Only four patients (20%) had ACTH levels below 5 pg/ml. The results of dynamic testing with dexamethasone suggested adrenal adenoma in 100% of the patients. Seventy percent of adenomas were found in the left gland. The mean size of the lesion was 2.8±0.47 cm.ConclusionsIn dynamic testing, the criteria of non-suppression with high doses of dexamethasone were evident in almost all patients. ACTH measurement in our center was not reliable in identifying adrenal adenoma as a cause of CS.     

Tinea capitis. Experiencia de 2 años en un hospital de pediatría de Buenos Aires,Argentina

Tinea capitis is an infection caused by dermatophytes of the genera Microsporum and Trichophyton, and constitutes a major health problem in Argentina. The aim of the present study was to find out the incidence of those etiological agents and the therapeutic response in patients attending a High-Complexity Paediatric Hospital within a two-year period. A total of 98 tinea capitis were diagnosed, 13 of which were Celsus kerion. Microsporum canis was isolated in 61.28%. The range of values for minimum inhibitory concentrations were >32, 0,06–4; <0,015–2; <0,015–0.25; 0.13–8; 0.06–128 μg/mL for fluconazole itraconazole, voriconazole, terbinafine, ketoconazole and griseofulvin, respectively.     

Eficiencia de las unidades de agudos de geriatría frente al resto de servicios hospitalarios. Análisis de la casuística de 5 años ajustada por GRD

Introduction

Hospital occupancy rate by older patients is high, and it will be even higher in the future. Their hospital stay is usually longer, making it important for hospitals to develop structures with the best efficiency possible.

Vegetación briofítca de las sierras de Filabres,Cabrera, Alhamilla y Cabo de Gata (Almería,SE de España)

The bryophyte vegetation of the Almería Province (SE Spain) has been studied according to the Braun-Blanquet method. Twenty-nine communities have been recognized, of which four are aquatic (classes Montio-Cardaminetea Braun-Blanquet & Tiixen 1943 and Platyhypnidio-Fontinalietea antipyreticae Philippi 1956), five terricolous acidophilous (classes Ceratodonto-Polytrichetea piliferi Mohan 1978 and Dicranelletea heteromallae Mohan 1978), 15 terricolous basiphilous (class Barbuletea unguiculatae Mohan 1978), four saxicolous (classes Racomitrietea heterostichi Neumayr 1971, Grimmietea anodontis Hadac & Vondraček in Jezek & Vondraček 1962 and Neckeretea complanatae Marstaller 1986) and one epiphytic (class Frullanio-Leucodontetea sciuroidis Mohan 1978 emend. Marstaller 1985). Three associations have been described as new: Rhizomnio punctati-Fissidentetum taxifolii (meso-hygrophilous, sciophilous, terri-humicolous, edaphically indifferent, on slopes close to running water), Plagiochasmo rupestris-Athalamietum spathysii (xerophilous, photo-sciophilous, chasmo-comophytic, basiphilous, in deep cavities of volcanic and sedimentary rocks) and Homalothecio aurei-Scleropodietum touretii (meso-xerophilous, photo-sciophilous, terricolous, edaphically indifferent, in rocks and humiferous slopes). Studies of the dynamics of the communities were undertaken.     

Contribución al conocimiento de los líquenes epifíticos del Valle de Sanabria (Zamora,España)

A catalogue of epiphytic lichens from the Sanabria valley (Zamora) is presented in this study. A total of 145 taxa are reported. According to our data, 137 taxa are new records for Zamora Province. For each species, ecological and chorological remarks are included. Chaenotheca furfuracea, Chromatochlamys muscorum, Cladina arbuscula subsp. mitis, Degelia atlantica, Julella lactea, Mycobilimbia hypnorum, Nephroma parile, Pannaria ignobilis, Pannaria pezizoides, Peltigera britannica, P. hymenina, Pertusaria ophthalmiza, Rinodina archaea, R. conradii, Thelenella modesta and Xylographa abietina are specially considered, due to their chorological implications in the Iberian Peninsula. We highlight the area “arroyo de las Truchas”, in Cobreros, because of the particularly wide diversity of epiphytic lichens.     

Thirty years of the "Asociación Española de Micología"

Since the foundation of the "Asociación Espa?ola de Micología" thirty years ago, we have consolidated the Spanish mycological community and also witnessed remarkable changes, not only in the Spanish society but in the scientific community as a whole. As it usually happens to human beings, during this time the "Asociación Espa?ola de Micología" has matured transforming itself into a solid scientific society. However, the "Asociación Espa?ola de Micología" will have to continue its transformation to adapt to new changes. This article shows the most relevant aspects in the history of the "Asociación Espa?ola de Micología" as well as new challenges that the society might face in the future.     

Prevalencia de sobrepeso y obesidad en niños y adolescentes de 2 a 16 años

ObjectivesTo estimate the prevalence of obesity and overweight in children and adolescents in our city and to investigate the associated factors.Subjects and methodsA cross-sectional study of 1317 children and adolescents aged 2-16 years. Multistage probability sampling was used to select three groups of subjects: 411 aged 12 to 16 years, 504 aged 6 to 12 years, and 402 aged 2 to 6 years. Body mass index was calculated, and obesity and overweight were diagnosed using the threshold levels of the International Obesity Task Force for children and adolescents. Parents were asked about eating habits, health, social, and demographic aspects. Results are given as percentages (95% confidence interval). The relationship between obesity and overweight and the different variables was studied using multiple logistic regression. The adjusted odds ratio (OR) was calculated.ResultsAmong children and adolescentes aged 2-16 years, 9.5% (8.0%-11.0%) were obese and 22.4% (23.3%-24.6%) were overweight. Of subjects aged 12-16 years, 8.5% (5.9%-11.2%) were obese and 20.5% (16.7%-24.3%) were overweight. In the groups aged 6-12 years and 2-6 years, rates of obesity and overweight were 11.6% (8.9% -14.3%) and 31.0% (27.0-35.0) and 8.0% (5.4%-10.6%) and 13.6% (10.3%-16.9%) respectively. Obesity or overweight was associated to age (OR 1.21; P< 0.001), maternal obesity (OR 10.99; P= 0.008), a birthweight higher than 4 kg (OR 2.91; p 0.002), and formula feeding (OR 1.82; P= 0.005).ConclusionObesity and overweight in children and adolescents are highly prevalent problems in our city.
