A prospective risk factor study was carried out for SSI in patients who underwent non-traumatic abdominal surgery, comparing an institutional (Secretary of Health) and a private third-level hospital during the period from October 2001 to May 2002. We studied 527 patients with 21 cases (3.98%) of SSI and four deaths due to this cause, 0.75% of the total population and 19% of patients with SSI. The mean age was 47.5 +/- 19.1 years, and there were 195 (37%) males and 332 (63%) females. The incidence of SSI in the private hospital was 2.1% and in the institutional hospital 5%, without statistical significance (p = 0.09). Within the infected group we found 14 superficial infections, 5 deep infections, and 2 infections in the organ or surgical field. Variables included i...

Estimarla en población mexicana y establecer el tiempo de exposición que la induce permitiría calcular intervalos de riesgo. Métodos: de 2005-2012 se cuantificó la RUV solar mediante radiometría terrestre, y se comparó con el índice UV público. Determinamos la DME en 90 individuos con los fototipos prevalentes en México (III, IV, V) y se estimó el tiempo para desarrollar quemadura solar. Resultados: las DME promedio para los fototipos III, IV y V fueron 39 (IC 95%: 35-42), 48 (IC 95%: 42-53) y 84 (IC 95%: 75-92) mJ/cm 2 , respectivamente (análisis de varianza [ANOVA], p ≤ 0.001). Aproxi-madamente, el 80% de la RUV diaria se acumula entre 10:00-16:00 h. El 77% de la dosis UV anual se recibe de marzo-octubre. El índice UV público tuvo una correlación alta con el cuantificado a nivel terrestre (r = 0.89; p ≤ 0.001). Conclusiones: México recibe niveles elevados de RUV de f...

We aimed to elucidate the mechanism of adhesion of EPC to diabetic and non-diabetic arteries and to study the effect of the anti-diabetic drug pioglitazone. Peripheral blood mononuclear cells were isolated from healthy donors. Human internal mammary arteries (HIMA) were isolated from patients who underwent coronary artery bypass surgery. EPC were labelled with 111In-oxine and perfused to HIMA in a perfusion chamber. Stromal derived factor-1 (SDF-1) and cyclooxygenase-2 (COX-2) were assessed by immunohistochemical analysis. CXCR-4 expression was assessed by flow cytometry. Adhesion of EPC was increased in HIMA from diabetic patients and was reduced after preincubation with 15 mM glucose for 72 h. EPC adhesion and CXCR-4 expression were inversely correlated. COX-2 and SDF-1 immunostaining in HIMA were positively correlated. Pioglitazone (1 microM) increased the adhesion of EPC to HI...

Dermatology has been one of the specialties where it has reached great development (Teledermatology). When the observation is made simultaneously by the outreach specialist and by the non-specialist at the workplace, it is called synchronous teledermatology, and asynchronous when information is filmed, stored, and presented to the specialist at a later time. To evaluate efficacy and reliability of asynchronous teledermatology for adequate diagnosis of skin diseases. Fifty patients with dermatologic disorders were seen in a poor tropical rural zone, first by non-dermatologists in conventional consultation and then by dermatologists to obtain a diagnosis (gold standard); the latter step consisted of evaluation of filmed lesions by another group of dermatologist later on. There was a high concordance of diagnosis between the two groups of dermatologists when kappa analysis was performed. It appears important to use these technological ...

To estimate it in our population and establish the time of exposure inducing it during daily activities would allow us to calculate risk intervals. From 2005-2012, the UV solar radiation was measured with terrestrial radiometry and compared to public UV index (UVI). We determined the MED in 90 individuals with the prevalent phototypes in Mexico (III, IV, V), and estimated the time needed for the development of sunburn. The average MED for phototype III was 39 (IC 95%: 35-42) mJ/cm2, for IV 48 (IC 95%:42-53) mJ/cm2, and for V was 84 (IC 95%:75-92) mJ/cm2 (ANOVA, p ≤ 0.001). Approximately, 80% of the daily UVR was accumulated between 10:00-16:00 h, and 77% of the annual UV dose is received between March-October. The public UVI had a high correlation with the one quantified at terrestrial level (r = 0.89; p ≤ 0.001). Mexico receives continuously high levels of UVR. Phototype III will pres...

In 1999 appeared the first therapeutic guidelines, after that new therapies have been assessed without substantial success. To describe treatment changes for ICH in a regional Mexican hospital and to assess their impact on clinical evolution. We accomplished a retrospective study of patients admitted between 2000 and 2006. We included those elder than 15 years with tomographyc diagnostic of ICH. Patients with head injury four weeks before or undetermined initial National Institute of Health Stroke Scale (NIHSS) were excluded. Epidemiological, clinical characteristics and kind of therapy were studied. We analyzed 175 patients with mean age of 62 years. Etiology and localization more frequently were arterial hypertension and lobar, respectively. More than 20% were intubated and approximately one half of these admitted in intensive care unit. Angiotensin converter enzyme inhibitors were the medicaments more usuall...

A clinical trial involved 33 patients with diffuse opacities on the enamel surfaces of maxillary incisors due to effects of dental fluorosis. The protocol of treatment 3 steps: (1) cleaning and enamel etching with 37% phosphoric acid in order to eliminate the layer that covers the fluorotic enamel surface and allow better penetration of the bleaching agent, (2) application of 5% sodium hypochlorite to remove stains caused by organic material, and (3) filling the opened micro-cavities with a light-cured, composite surface sealant to prevent restaining. The whiteness of the enamel lesions before and after treatment were expressed in L*, a*, and b* color space measurements using a Minolta Chroma Meter CR300. Analysis of parameters of [symbol:see text]E (L*, a*, b*) showed that changes were observed in the L* (brightness...

Retrospective study of patients diagnosis with amoebic liver abscess in Hospital Central in San Luis Potosí, Mexico. We included patients greater than 15 years of both sexes. We excluded those with probable pyogenic abscess, immunosupression, history of abdominal or biliary surgery, abdominal neoplasm abdominal or sepsis. We identified patients with good response to medical treatment and patients who needed the abscess drained. We studied the ultrasound findings, plasma levels of albumin, alkaline phosphatase and bilirubin. We analysed 45 patients, 31 had a good response (controls) and 14 needed drainage (cases). The medians of the variables with statistical significance in bivariate analysis were: albumin 2.65 g/dl and 1.7 g/dl (p < 0.001); alkaline phosphatase 133 U and 259 U (p = 0.02) and diameter of absences 5.9 cm and 9.95 cm (p < 0.001), contr...

Bergman's minimal model (Min-Mod) is also being used to estimate IS, but there are doubts as to its equivalence with Clamp. The objective of the present study is to determine if Clamp and the tolbutamide and insulin techniques of Min-Mod are equivalent. Meta-analysis based on a bibliographic search from 1970 until the present was made for the MeSH terms: insulin resistance, hyperglycemic-clamp, euglycemic-clamp, Min-Mod, minimal model approach. Concordance was determined with both simple and intraclass correlation and Bland and Altman's concordance limits using R. Three of the 109 articles found were included. The concordance limits indicate that Clamp and Min-Mod are not equivalent, which could result in diagnostic errors if the accepted cut-off point is used for both methods. ...

A cohort study was conducted in the City of San Luis Potosí between May 2001 and April 2002. The study population consisted of 80 school male and female children, selected at random, aged 6 to 19 years of age. The dose was quantitated during an entire schoolyear by recording the time each student was exposed to sunlight. Ultraviolet radiation was simultaneously monitored with terrestrial radiometry equipment. Holidays and weekends were excluded. Data were analyzed using univariate analysis and comparative analysis by sex and months of exposure. A regression model was fit to explain the dose of solar exposure. The erythemally weighted UV dose for Mexican schoolchildren averaged 16,456 J/m2/year. Differences by gender were found: 14,264 J/m2/year in females vs. 18,648 J/m2/year in males (Kolmogorov-Smirnov, p = 0.003). No significant differences were found among grou...
