Epidemiología de la acromegalia en España

Epidemiology of acromegaly in Spain does not differ from that reported in other published series. Prevalence rate is approximately 60 cases per million, peak incidence occurs in middle age, more women are affected (61%), and there is a substantial delay between occurrence of the first symptoms and diagnosis. Studies REA (Spanish Acromegaly Registry) and OASIS analyzed the epidemiology, clinical characteristics, and management of the disease in Spain. Surgery, performed in more than 80% of patients, has been (and continues to be) the main treatment for the past four decades. In the past decade, however, more patients have received somatostatin analogs (SSAs) as first-line treatment. Use of radiation therapy has significantly decreased in recent decades. Somatostatin analogs (SSAs) are the most commonly used drugs, administered to 85% of patients; however, only 12%-15% continue on drug treatment alone. The surgical remission rate was 38.4% in the last decade, with a significant improvement over decades. Preoperative treatment with SSAs has no influence on surgical cure rates. Second-line therapies used after surgical failure in the past decade included SSAs in 49% of patients, repeat surgery in 27%, radiotherapy in 11%, pegvisomant in 15%, and dopamine agonists in 5%. Mean cost of acromegaly treatment was 9.668€ (data estimated in 2009 and adjusted in 2010), of which 71% was due to the cost of SSAs. Patients treated with pegvisomant have a more aggressive form of the disease and higher comorbidity rates.     

El papel de la mitocondria en el dolor de la neuropatía diabética

Diabetes is a metabolic disease affecting approximately 300 million people worldwide. Neuropathy is one of its frequent complications, and may affect sensory, motor, and autonomic nerves. Its pathophysiology has not fully been elucidated. Several hypotheses have been proposed, and mitochondria have been suggested to play a significant role. This article reviews the mechanisms involved in mitochondrial dysfunction and development of diabetic neuropathy, consisting mainly of oxidative and inflammatory stress, changes in intracellular calcium regulation, apoptotic processes, and changes in mitochondrial structure and function that may lead to development of diabetic neuropathy.     

Epidemia de tiña por Trichophyton tonsurans en un área sanitaria de la Comunidad de Madrid (España)

BackgroundTrichophyton tonsurans is a dermatophyte fungus that can cause ringworm outbreaks. In our health area in September 2013, two cases of T. tonsurans ringworm were diagnosed in children who lived in a Children's Centre.AimsTo determine the origin and extent of the outbreak.MethodsMycological cultures of scalp and skin samples from the contacts of the diagnosed cases were performed, as well as environmental samples from the Children's Centre. The patients started with a treatment for their ringworm, and an environmental disinfection of the centre was performed.ResultsTwelve cases of ringworm were detected, along with three asymptomatic scalp carriers of T. tonsurans among 20 children in the Centre. The index case was a resident in whose family, that had just returned from their country of origin, Nigeria, three cases of ringworm were diagnosed. From November 2013 to February 2014 another five cases of ringworm were diagnosed among schoolmates of three cases from the Children's Centre.ConclusionsThe antifungal treatment of the children resulted in the mycological and clinical resolution, and from February to November 2014 no other cases of ringworm by T. tonsurans in the same health area were diagnosed.     

Evaluación de la realización del cribado del pie diabético en Atención Primaria

AimTo ascertain whether patients with type 2 diabetes are screened for diabetic foot, and to analyze the factors related to patients and centers associated to performance of such screening.Material and methodsA multicenter, epidemiological, cross-sectional study was conducted. The clinical records of 443 patients with type 2 diabetes monitored at Primary Care for at least 12 months were reviewed. Demographic and healthcare variables and characteristics of the primary care center were recorded.ResultsIn the previous year, 51.2% of patients had been trained on foot self-care, 56.4% had undergone foot inspection, 39.5% had been examined with a monofilament, and palpation of peripheral pulses and measurement of the ankle-brachial index were performed in 45.8 and 10.1% of patients, respectively. Diabetic foot screening (inspection, monofilament testing, and palpation of peripheral pulses) was performed in 37% of study patients. Ulcer risk stratification was done in 12.4% of patients. A significant association was found between diabetic foot screening and presence of foot deformities (P < .001), history of neuropathy (P = .005), and history of peripheral artery disease (P < .05). Screening was also associated to some characteristics of the center, such as reception of information about goal achievement (P < .001) and economic incentives for goal attainment (P < .001).ConclusionsCompliance with diabetic foot screening and ulcer risk stratification in patients with type 2 diabetes in Primary Care was poor.
