Background: Recently, it has focused the role of exposure to environmental tobacco smoke in the etiology of dental caries, so we plan to evaluate the association between environmental tobacco smoke inhalation and caries experience in 10-15-years old children. Methods: A transversal descriptive study was designed. Carried out in the Primary Dentistry Unit. 9th Health Depart ment. Valencian Country (Spain). 380 children random sample was selected (following the inclusion criteria). Each participant was clinically explored, then answered a self-administered opi nion test about contact with tobacco smoke. Measurements: DMF-T and df-t indexes and their components, plaque and gin gival indexes, contact with tobacco smoke frequency (at home or not), own opinion about tobacco effects and present or future tobacco consumption. Results: Children living with smokers at home showed a decayed teeth average of 1,9 2,34, while those not living with smokers had 1,03±1,46 (p< 0,001). df and DMF average inde xes for children exposed and not exposed to tobacco smoke were 0,27 ±0,78 (df)and 1,62±2,21 (DMF) and 0,10 ±0,47 (df) and 0,92 ±1,40 (DMF) respectively (p=0,039 y p<0,001). Conclusions: In our study conditions, coexistence with environmental tobacco smoke is associated with a higher caries prevalence in both deciduous and permanent dentitions in 10 15-years-old children.

Blood metabolites concentrations present diurnal variations related to food intake. An experiment was carried out to evaluate diurnal variations in the blood metabolites concentration related to feeding behavior in grazing lactating cows. Eight Frisian cows, 60 to 90 days of lactation, were kept grazing, during 60 days, on a spring paddock mostly of rye grass and allotted in two groups. Group, GP-C, (n=4) was supplemented with 3 kg of concentrate and group GP, (n=4) was not supplemented. Grazing behavior was observed every 10 minutes during days 56 and 57. Blood samples were obtained on the day 58 every 4 hours to measure plasma concentrations of urea, albumin, βOH-butyrate, cholesterol, triglycerides, glucose, Ca, Pi and Mg. Cows spent 30.4% of the day grazing, mostly during the day, and 31.7% of the day ruminating, mostly during night. Concentration of all the metabolites remained unchanged in the GP-C, however, in GP the plasma concentration of urea, βOH-butyrate and triglycerides increased and phosphate decreased during a day. Thus, in dairy cows fed only on pasture, blood concentrations of most of the metabolites determined in the metabolic profiles remained unchanged during the day, excepting urea, βOH-butyrate, triglycerides and Pi, and supplementation with concentrate decreases those variations.

Since the publication in 2009 of the Guidelines on the Diagnosis and Treatment of Irritable Bowel Syndrome of the Asociacin Mexicana de Gastroenterologa (2009 Guidelines), there have been significant advances in our knowledge of the epidemiology, pathophysiology, diagnosis, and treatment of this disease.To present a consensus review of the most current knowledge of IBS, updating the 2009 Guidelines by incorporating new internationally published scientific evidence, with a special interest in Mexican studies.The PubMed literature from January 2009 to March 2015 was reviewed and complemented through a manual search. Articles in English and Spanish were included and preference was given to consensuses, guidelines, systematic reviews, and meta-analyses. Statements referring to the different aspects of the disease were formulated and voted upon by 24 gastroenterologists employing the Delphi method. Once a consensus on each statement was reached, the quality of evidence and strength of recommendation were determined through the GRADE system.Forty-eight statements were formulated, updating the information on IBS and adding the complementary data that did not appear in the 2009 Guidelines regarding the importance of exercise and diet, diagnostic strategies, and current therapy alternatives that were analyzed with more stringent scientific vigor or that emerged within the last 5 years.We present herein a consensus review of the most relevant advances in the study of IBS, updating and complementing the 2009 Guidelines. Several studies conducted in Mexico were included.

This review of the literature on palmoplantar hypokeratosis, a process that was first indentified only 10 years ago, discusses the current state of our understanding, the therapeutic options available, and the debate about etiology. Forty-four publications reporting 69 cases were found. Palmar or plantar hypokeratosis occurs mainly in women (76.8%) and age at the time of a first visit to a physician ranges from 42 to 84 years. Most cases present between the ages of 51 and 70 years. The majority of patients have had solitary lesions usually located on the right palm, particularly in the regions of the thenar (in 44/79 lesions [55.7%]) or hypothenar eminences (in 11/79 lesions [13.9%]). In only 8 cases was there a history of prior trauma at the site. Studies using polymerase chain reaction techniques to identify human papillomavirus involvement were negative in most cases. These hypokeratotic lesions are localized epidermal depressions formed by an abrupt thinning of the stratum corneum, providing a singular histopathologic feature. This condition can currently be considered a localized keratinization disorder affecting zones where there is a thick stratum corneum. The precipitating cause is unknown and a definitive treatment remains to be found. The mechanism would be the localized failure of a clone of keratinocytes during differentiation toward normal palmoplantar hyperkeratinization. © 2012 Elsevier Espana, S.L. and AEDV.

The multinational EDGE (Effectiveness of Diabetes control with vildaGliptin and vildagliptin/mEtformin) study assessed the effectiveness and tolerability of vildagliptin versus other oral antihyperglycemic drugs (OAD) when added to monotherapy in patients in the real-world setting.Prospective, real-world observational study. The primary endpoint (PEP) was the proportion of patients achieving a reduction in HbA1c > 0.3% without peripheral edema, hypoglycemia, discontinuation, dueto gastrointestinal event, or weight gain > 5%. The secondary endpoint (SEP) was the proportion of patient achieving HbA1c < 7% (at month 12), without proven hypoglycemia or weight gain ( 3%).Of the 3,523 patients enrolled in Mexico, 2,847 were in the vildagliptin and 676 in the comparator cohort. The PEP was reached in 61.8 and 53.2% in the vildagliptin and comparator cohorts, respectively. The unadjusted odds ratio was 1.42 (95% CI: 1.19-1.68) in favor of vildagliptin. A similar advantage for vildagliptin-based therapies was seen for the SEP. The percentage was lower in the vildagliptin (n = 145; 5.0%) than in the comparator group (n = 95; 14.0%).Vildagliptin, added to a first-line OAD monotherapy, allows patients to reach target HbA1c without experiencing significant adverse events.

Cephalometric norms facilitate diagnosis and treatment planning in orthodontics. These are obtained primarily from adult Caucasian population. It has been suggested that these norms may vary between different ethnic groups, and there is still little information about Chilean cephalometric norms in growing individuals. A sample of 48 lateral radiographs was obtained from growing individuals (23 women and 25 men) with normal occlusion and harmonious profile taken between January and July 2012 at Universidad de los Andes, including 414 individuals. Radiographs were analyzed cephalometrically, obtaining soft and hard tissue values for vertical and sagittal parameters. Descriptive statistics were obtained, and differences between sexes were analyzed with student´s t-test. When compared to Caucasian standards, subjects in the sample present with a Class II skeletal tendency due to a retrognathic mandible, an open facial axis, with upper and lower incisor protrusion. They also showed more protruded upper and lower lips with respect to Caucasian standards. There are differences between the cephalometric measurements observed on the individuals of the sample compared to international standards, which are evidenced at mandibular, dental and labial structures. © 2015, Universidad de la Frontera.

The restoration of the breast is an essential component in the curative treatment of cancer after mastectomy, as a scar or reconstruction with a poor cosmetic outcome translates into constant reminder of the disease. We propose a model of aesthetic subunits of the breast for mammary reconstruction, since the breast itself has different volume distribution that are characteristic of each patients body habitus, and avoiding in the reconstruction a single focal point in the perfectible breast. A total of 32 abdominally base flap reconstructions were performed for the restoration and integration of the subunits, as the abdominal flaps offers the advantage of being molded according to need, a characteristic not met by the use of alloplastic materials, for soft transition of the chest wall to the observer. The reconstruction of the nipple areola complex, procedures for symmetrization of healthy native breast, such as reduction or mastopexy, were performed 6 months after the initial procedure, where we can use the same subunits to assess the outcome and improve areas of continuity with lipoinjection application of fat or scar revision. Twenty-eight of the reconstructions, had a good contour of the flap in continuity with the chest wall, and proper positioning of the breast groove with good symmetry with the contralateral breast. Four reconstructions failed to unifiy the subunits of the breast, 2 of them with an appearance of patch flap, and 2 with a low positioning of the new inframamary fold. The proposed subunit principle approach to breast reconstruction may be used effectively in preoperative planning and second staged procedures, to obtain superior aesthetic outcomes in breast reconstruction, with a good flap positioning, volume distribution and incision placement and direction, having as a result the unification of the subunits as a whole.

Hair and scalp dermoscopy, also called trichoscopy, is an in-office technique that may be performed with a handheld dermoscope or a digital videodermoscope with a 10x to 70x magnification images. This method of evaluation for alopecia is now gaining importance for diagnosis and follow-up of patients. Cicatricial alopecia is less frequent in clinical practice comparing to noncicatricial alopecia, and are commonly divided in lymphocytic, neutrophilic or mixed, according to the inflammatory cells observed. Regardless the low frequency, they offer a vast number of dermoscopic structures divided into four groups: 1) hair shafts, 2) hair follicle openings, 3) perifollicular epidermis, and 4) blood vessels. The most common structures in cicatricial alopecia are the loss of orifices, milky red areas, thick arborizing vessels, perifollicular scales, perifollicular hyperplasia with starburst pattern and 3D dots appearance. Trichoscopy is also useful in guided scalp biopsy in cicatricial alopecia and in therapeutic follow-up.

Blue nevus is a benign dermic melanocytic proliferation, which could mimic benign or malignant lesions including melanoma. Dermoscopy is a useful non-invasive diagnostic tool in the diagnosis of melanocytic lesions, including blue nevus. Its main dermoscopic feature is homogeneous blue pattern or structureless steel blue, nevertheless we can find some other dermoscopic blue lesions, polychromic blue nevus and even dermoscopic structures also seen in melanoma, so the differential diagnosis may be difficult. Blue lesions assessment must be accompanied by both the integration of all clinical data such as dermoscopic features; and the lack of correlation between these and/or suspicion of malignancy makes mandatory the surgical excision.

The breast implant associated with mastopexy actually is one of most difficult plastic surgeries. In fact, it is a surgery where the surgeon has to use his higher capabilities and skills in order to decide with precision the best relationship between ideal sizes of the breast implant and skin excess. The purpose in this paper is to present a breast lateral and medial flaps technique for augmentation mastopexy surgery looking for a better breast design and resistance on the final result. The technique was created on breast circulation basis, skin excess and better definition and resistance about the aesthetical breast results in the augmentation mastopexy surgery utilizing the T scar technique. The early results were acceptable in order to get breast definition, breast structure and implant protection. The long term results, especially breast resistance, will need to be evaluated. In our opinion, the technique is easy to execute, it allows a satisfactory aesthetic result giving the perception of high security on the implant position, but its resistance in a long term view needs better evaluation.
