Background: Fat grafting is increasingly common in plastic surgery procedures. The discovery of stem cells in fat tissue has given a new direction to the use of fat as a therapeutic tool for other patient conditions. Only one experimental study in rats shows dermal changes after application of lipofilling. For this reason, the authors conducted this study to evaluate skin changes in patients after application of the technique. This study aimed to observe histologic changes in the skin of patients undergoing fat grafting. Methods: Fat grafting was performed in the preauricular region on one side of patients undergoing face-lifts at the Jalisco Reconstructive Surgery Institute, Guadalajara, Mexico. Preauricular skin was used in this procedure as a withdrawal study and control condition. Hematoxylin-eosin and Masson staining was performed to assess dermal and epidermal thickness, vascularity, and collagen behavior. No inferential statistics were registered with the Wilcoxon test. Results: The study investigated 16 patients to observe statistically significant differences in dermal thickness, the presence of immature collagen (neoformation), and arteries. No difference in epidermal thickness was observed. Conclusions: The study showed a regenerative effect with fat grafting that included an increased thickness of the dermis, collagen neoformation, and the presence of increased vascularity in local skin subjected to treatment.

Previous publications have suggested that living in a nonintact family household and socializing with girlfriends who smoke or who consume alcoholic beverages favor the development of health-risk habits and customs in adolescents. However, their relationship with unplanned pregnancy in adolescents has not been determined. We investigated the association between family structure, employed mother, and female friends with health-risk habits and behaviors with unplanned pregnancy in adolescents (n = 3,130). After adjusting for low maternal educational level and low family income, logistic regression analyses showed that having an employed mother and socializing with girlfriends who have health-risk habits or behaviors, rather than living in a nonintact family household, appear to be the most important health-risk factors for unplanned pregnancy in adolescents. It is important for health-care programs for adolescents to be revised and for their strategies be strengthened in order to reach the objectives for which they were created. © 2013 The New York Academy of Medicine.

Background: Recent publications show that smoking and alcohol use among adolescents with unplanned pregnancy is increasing and the causes need to be further studied. Objective: To determine the association between living in a non-intact family household and the presence of smokers and consumers of alcoholic beverages in the adolescents’ environment with smoking and consuming alcoholic beverages in adolescents with unplanned pregnancies. Methods: A cross-sectional study was carried out among 785 pregnant adolescents, aged 13-19 years. Data was collected by trained interviewers using a self-administered questionnaire. The association was determined using multivariate logistic regression analysis. Results: In adolescents with unplanned pregnancies, the prevalence of active smoking was 21.2% and of alcohol consumption, 41.5%. The percentage of smoking at home was 57.4% and alcohol consumption, 77.5%. Approximately, 80.3% of adolescents with unplanned pregnancies had friends who smoked and 90.6% consumed alcoholic beverages. Multivariate logistic regression analysis shows that having friends who smoke or who consume alcoholic beverages is the most important risk factor for substance use in adolescents with unplanned pregnancies. Smoking and alcohol consumption at home are not associated with smoking in adolescents with unplanned pregnancies. Conclusion: Socializing with friends who smoke and/or consume alcoholic beverages constitutes the most important risk factor for substance use among adolescents with unplanned pregnancies. © 2016, Makerere University, Medical School.

Objective: Analyzed a case of woman with virilizan ovary tumor, where clinics manifestations made easy diagnosis of a anexial tumor producing masculine hormones with neoplastic thorax effusion and ascites. Specific tumoral serum marks for diagnosis, and posoperatory evolution. We made a medical prospective literature review. Methods: We studied a female case 35 years old, with an androgenic malignity ovary tumor, Analysis was worked in a Regional General Hospital of a State of Mexico, Mexico last year. Prospective studying a tumor of the ovary, produces masculine hormones. Discussion: Rare tumor, represents, almost 0.5% all ovarian tumors. It's secrets masculine hormones; with broaden voice, acne, facial and corporal hair increased, large clitoris, androgenic calvicie patter. Those tumors grow in all age's women groups, but usually in young women, almost is unilateral (95%). We show a clinical case of woman, 35 years old with androgenic dates, She carried out surgery for ovarian tumor. Histopathology report confirmed a malign ovary cordons sexual cells, with high malign grade compound, approximated 30 cm mayor diameter with integral capsule. Stage IC. Were used 6 cycles intravenous systemic chemotherapy. At present, her tumoral marks are negative and gradually have been disappeared androgenic clinical manifestations. Conclusions: Rare malign ovary tumor, produces androgenic clinical manifestation. Grove up tumor marks like serum testosterone; cytorreductive surgery is cornerstone treatment. Prognosis disease is up to grade of cell differentiation and stage in surgical-pathological events. Five years survive in stage I, is approximate in 70 to 90% of cases. © 2014 Lifescience Global.

The first pandemic of the 21stcentury occurred in 2009 and was caused by the H1N1pdm influenza A virus. Severe cases of H1N1pdm infection in adults are characterized by sustained immune activation, whereas pregnant women are prone to more severe forms of influenza, with increased morbi-mortality. During the H1N1pdm09 pandemic, few studies assessed the immune status of infected pregnant women. The objective of this study was to evaluate the behavior of several immune markers in 13 H1N1pdm2009 virus-infected pregnant (PH1N1) women, in comparison to pregnant women with an influenza-like illness (ILI), healthy pregnant women (HP) and healthy non-pregnant women (HW). The blood leukocyte phenotypes and the serological cytokine and chemokine concentrations of the blood leukocytes, as measured by flow cytometry, showed that the CD69+ cell counts in the T and B-lymphocytes were significantly higher in the PH1N1 group. We found that pro-inflammatory (TNF-α, IL-1β, IL-6) and anti-inflammatory (IL-10) cytokines and some chemokines (CXCL8, CXCL10), which are typically at lower levels during pregnancy, were substantially increased in the women in the ILI group. Our findings suggest that CD69 overexpression in blood lymphocytes and elevated levels of serum cytokines might be potential markers for the discrimination of H1N1 disease from other influenza-like illnesses in pregnant women. © 2014 Cérbulo-Vázquez et al.
