Foot ulceration risk factors in type 2 diabetes mellitus [Factores de riesgo de ulceración de los pies en diabéticos tipo 2.]

OBJECTIVE: To identify risk factor prevalence for development of foot ulcers in patients with type 2 diabetes (DM2). METHODS: A cross sectional study, of 2067 patients with DM2 from seven primary care units was conducted. A questionnaire exploring age, sex, occupation, time from diabetes mellitus diagnosis (DMD), and data concerning neuropathy, vascular changes, and presence of infections, anthropometry, and gait was applied. RESULTS: We found mean age, 59.96 +/- 11.47 years and time from DMD, 10.2 +/- 8.09 years. From 1360 women, 65.8 % presented the following risk factors: age, 34.7 %; schooling, 49.5 %; time from DMD, 38.8 %; occupation, 20 %; smoking, 24.3 %; alcoholism, 4.6 %; fasting glucose disturbance, 78 %; ulcer history, 10 %. In relation to associated diseases, 67.5 % of patients had one or more antecedent. The presence of risk factors in the sample was 9.716 +/- 2.52, of which 6.259 +/- 1.59 were modifiable. CONCLUSIONS: Patients studied presented high risk factor prevalence for development of foot ulcer. The majority of RF is potentially modifiable by adjusting patients' customs and habits

Epidemiological and clinical characteristics of scorpionism in Colima, Mexico (2000-2001)

We analyzed 13,223 clinical records of patients treated for scorpion sting in hospitals of the Mexican Institute of Public Health and the Ministry of Health in the state of Colima, Mexico, during the years 2000-2001. A database containing demographic, epidemiological and clinical information was constructed and analyzed retrospectively. Patients were classified in the categories as mild (49.2%), moderate (33.8%) and severe (17.0%) according to commonly accepted standards. Most common symptoms recorded were local pain (94.7%), local paresthesia (67.2%), pruritus/itching (54.3%), sensation of a lump or hair in the throat (47.3%), and sialorrhoea (27.7%). The median time from sting to admission to the emergency room (patient delay) was 33 min (interquartile range: 12-60). We found that older and clinically severe patients were significantly associated with longer times of admission to the emergency room. Age was significantly associated with clinical severity: the age group 0-10 years included a higher proportion of severe cases than the group 11 years and older. In four cases, patients died. An educational campaign to inform the population about the importance of receiving prompt attention following a scorpion sting has potential value in reducing complications in the emergency room. 2006 Elsevier Ltd.

[Monitoring triatomid bug (Hemiptera: Reduviidae) presence by sentinel chicken coops in Southern Jalisco State, Mexico]

INTRODUCTION: Chagas disease is an important public health problem in Mexico. At least 30 Triatominae species, vectors of that disease have been recorded, most with domiciliary habits and tendency to invade human dwellings. OBJECTIVE: The usefulness of using chicken coops was evaluated for monitoring peridomestic triatomine presence, identity and infection with Trypanosoma cruzi. Materials and methods. A year-long, longitudinal field study was designed. Fifty chicken coops were placed in 50 human dwellings on three localities in Teocuitatlan de Corona County, Jalisco State, Mexico. The coops and human dwellings were routinely inspected to determine if the coops alone can monitor for the presence of triatomines. RESULTS: Significantly (p<0.05) more Meccus longipennis specimens (93.0%) than of Triatoma barberi (7.0%) were collected. Almost a third (31.3%) of M. longipennis and none of T. barberi specimens were collected in the coops. Meccus longipennis was found with infections of Trypanosoma cruzi of 25.7%, and T. barberi of 53.2%. Most triatomines were collected in spring and summer months. CONCLUSIONS: Chicken coops proved useful tools to detect presence of M. longipennis; however, they were not effective for T. barberi. The importance of M. longipennis as a potential vector was confirmed, and the possible primary vector role of T. barberi was established as well

Serotonin-dopamine interaction: Experimental evidence and therapeutic relevance [Interacción de la serotonina y la clopamina evidencia experimental e importancia terapéutica]

Objective: to associate serologic response to Helicobacter pylori (Hp) among seropositive university students and their families in western Mexico. Methods: we conducted a comparative transversal study, and randomized 30 nuclear families of 14 Hp-seropositive university students and 14 Hp-seronegative university students. We carried out seropositivity measurements (IgG) to Hp using the ELISA method. An analysis was performed utilizing the chisquared and Mann-Whitney U tests, with the aid of EPI INFO 2000 and SIGMA STAT 3.2 software. Results: global seropositivity in the families of infected students was 57 vs. 13% of the relatives of non-infected students (p = 0.000002). In families of Hp-positive students we found the following frequencies: parental (father and mother) 70%; mother 71%, and siblings 42%, while for seronegative individuals incidences were: parental 17% (p = 0.00005), mother 12% (p = 0.001), and siblings 10% (p = 0.0076). Conclusions: there is a greater prevalence of antibodies against Hp in the relatives of seropositive students. Copyright " 2008 ARÁN EDICIONES, S.
