Cetoacidosis diabética: Casuística 2008-2012, epidemiología y fisiopatología / Treatment of diabetic ketoacidosis using 2009 American Diabetes Association guidelines

Background: During 2009, new guidelines for the treatment of diabetic ketoacidosis were published by the American Diabetes Association. Aim: To assess the impact of new treatment guidelines on the evolution of patients treated for diabetic ketoacidosis (KAD). Patients and Methods: Anonymous data was obtained from computational medical records of patients treated for KAD at our institution two years before (“Traditional Protocol”) and TWO years after (“ADA-2009 Protocol”) the publication of the 2009 American Diabetes Association (ADA) KAD guidelines. Results: Twenty three patients aged 36.5 ± 15.1 years were treated with the traditional method and 23 patients aged 44.4 ± 21.1 years were treated following 2009 ADA guidelines. Among patients treated with the traditional protocol and treated following ADA 2009 guidelines, the diabetes type 1/type 2 ratio was18/5 and 19/16 respectively (p = NS), the glycosylated hemoglobin on admission was 12.6 ± 2.5 and 14.3 ± 2.7% respectively (p = 0.03), minimal blood pH was 7.15 ± 0.14 and 7.19 ± 0.09 respectively (p = NS), bicarbonate was required in seven and no patient respectively (p = 0.01), hypokalemia < 3.5 mEq/L occurred in 78.2 and 48.5% of patients (p = 0.03), the lapse until resolution was 28.7 ± 28.0 and 28.8 ± 20.6 hours (p = NS). Only one patient, treated following ADA 2009 guidelines, died. Conclusions: Introduction of the ADA-2009 protocol for the treatment of KAD resulted in decrease in the use of intravenous bicarbonate and a reduction in the incidence of hypokalemia. There was no impact neither in the lapse until resolution or lethality.

Identificación de las necesidades de capacitación docente de los jefes de programa de especialización médica / Identifying the main training needs of postgraduate medical program managers

Training of postgraduate medical specialty program managers (PMSPM) is essential for the proper development of their programs. Aim: To identify the main training needs of PMSPM at a medical school. Material and Methods: A mixed-methodology approach was implemented including focus group/interviews and the administration of the Program Managers Training Needs Assessment Questionnaire (PROMANAQ) developed by an expert panel with 59 items (with two sections: relevance/performance-self-perception). Higher priority was assigned to items with high relevance and low performance. Results: Forty five PMSPM completed the PROMANAQ (81.8% response rate). Both sections of PROMANAQ were highly reliable (Cronbach alpha of 0.95/0.97 for relevance/performance-self-perception, respectively). The items with higher priority value were evaluation of clinical educators, evaluation of teaching programs and accreditation of programs. Ten PMSPM were included in the focus group (18.2% of the universe). The findings of the qualitative component were concordant with the areas explored in the questionnaire. Conclusions: The PROMANAQ is valid and reliable to identify the training needs of PMSPM. The views of PMSPM must be taken into account for faculty development planning.

Bases fisiopatológicas para una clasificación de la neuropatía diabética / A new physiopathological classification of diabetic neuropathy

Nowadays, Diabetic Neuropathy (DN) is considered the most common cause of peripheral neuropathy in clinical practice. It can affect sensitive, motor or autonomic nerve fibers, with symmetric, asymmetric, acute or chronic presentations. Due to this variability, with multiple physiopathologic mechanisms involved, a complex clinical classification has been used until recently. The aim of this review is to present a new classification of diabetic neuropathy, based on its physiopathology. It is divided in metabolic microvascular and hypoxic, autoimmune and inflammatory, compressive, secondary to complications ofdiabetes and related to treatment. It must be understood that DN is notjust a functional disease, but a complication of diabetes with molecular and pathological substrates caused by hyperglycemia. Therefore, normalization of blood glucose is a fundamental step towards the successful prevention and treatment of DN.
