Since the industrial production of cigarettes in XIX century became possible, cigarettes price decreased and their availability increased significantly. Beside the economical income of the industry owners, the wide accessibility to tobacco products became connected to increased incidence of some diseases. Among "tobacco-related" disease we should mention: atherosclerosis (mainly coronary arteries), arterial hypertension, respiratory tract tumors, urinary tract tumors, digestive tract tumors, uterine cervix cancer, restrictive lung disease, consequences of hormonal abnormalities in women, and abnormalities of fetal, newborn and child development. Due to basic research we understood the diseases mechanisms. Although, the number of evidences of adverse effects of tobacco smoke on human health, the number of smoking population is still high. What activities should be taken for promoting life without tobacco smoke?

Screening often leads to finding conditions that are not at the stage or level that would classify them as disease but, at the same time, are not at a stage or level at which people can be declared entirely disease free. These "in-between" states have sometimes been designated as "predisease." Examples include precancerous lesions, increased intraocular pressure ("preglaucoma"), prediabetes, and prehypertension. When the goal of preventing adverse health outcomes is kept in mind, this review poses the idea that "predisease" as a category on which to act makes sense only if the following 3 conditions are met. First, the people designated as having predisease must be far more likely to develop disease than those not so designated. Second, there must be a feasible intervention that, when targeted to people with predisease, effectively reduces the likelihood of developing disease. Third, the benefits of intervening on predisease must outweigh the harms in the population. A systematic review of screening guidelines (published in 2003-2010) for 4 sample conditions (cervical cancer, glaucoma, diabetes, and hypertension) is included to assess whether they address these issues, followed by a discussion of the framework questions as they pertain to each condition.

We report the case of a patient who presented hypertension paroxysmal with acute pulmonary oedema followed by cardiocirculatory arrest during gynaecological surgery for resection of latero-aortic lymph nodes suspected to be cervical cancer metastases. This intervention, originally oncologic, has discovered ectopic phaeochromocytoma a posteriori. The management of perioperative serious adverse events revealing the undiagnosed phaeochromocytoma is discussed.

There is limited information on the health status of South Asians. Our objective was to examine the delivery of clinical preventive services to South Asian adults. We used data from a 2001 mail survey to a nationwide sample of South Asians. We quantified the percentage of eligible adults who received screenings for colorectal cancer, cervical cancer, breast cancer, high blood pressure, lipid disorders, and vaccinations against influenza, pneumococcus, and tetanus. We also calculated the number of individuals who were up-to-date with all their recommended preventive healthcare. One-fourth of South Asians were up-to-date with their recommended preventive services, while more than half were not up-to-date with their services. Having a regular source of care was significantly associated with being up-to-date on recommended schedules. Despite their high level of education, the majority of South Asians in the US are not receiving the appropriate amount of preventive health services.

Elevated interstitial fluid pressure (IFP) in tumors can cause metastatic dissemination and treatment resistance, but its study poses a challenge because of a paucity of noninvasive imaging strategies. In this study, we address this issue by reporting the development of a noninvasive tool to assess tumor IFP and interstitial hypertension-induced lymph node metastasis. Using mouse xenograft models of several types of human cancer, we used gadolinium diethylene-triamine penta-acetic acid (Gd-DTPA) as a contrast agent for dynamic contrast-enhanced MRI (DCE-MRI). Immediately after Gd-DTPA administration, a high-signal-intensity rim was observed in the tumor periphery, which moved outward with time. Assuming the velocity of Gd-DTPA to be equal to the fluid flow velocity, we used a simple model of peritumoral interstitial fluid flow to calculate the fluid flow velocity at the tumor surface (v(0)) based on the rim movement. Significant positive correlations were found between v(0) and IFP in all tumor xenografts. Moreover, the primary tumors of metastasis-positive mice displayed higher IFP and v(0) than the primary tumors of metastasis-negative mice. Findings were confirmed in cervical cancer patients with pelvic lymph node metastases, where we found v(0) to be higher compared with patients without lymph node involvement (P < 0.00001). Together, these findings establish that Gd-DTPA-based DCE-MRI can noninvasively visualize tumor IFP, and they reveal the potential for v(0) determined by this method to serve as a novel general biomarker of tumor aggressiveness.

The author emphasizes the achievements of the Polish Gynecological Society in the field of improving the health indicators concerning perinatal mortality among infants during the last two decades in Poland. Attention is paid to the contribution of the members of the Society to organizational change in Polish health care after 1990, which resulted in the improvement of the care of mother and child. It is also underlined that the members of the Society contributed to the creation of early detection system of breast and cervical cancer in Poland. However it is noteworthy that in 'Polish Gynecology' - the publication of the Polish Gynecological Society - the number of reports devoted to risky health behaviors of women during periconceptional period and pregnancy is scarce. The author draws attention to the percentage of women who smoke cigarettes and consume alcohol before and during pregnancy Emphasis is also placed on the problem of nutritional disorders (mainly pathological methods of dieting) among Polish women during the reproductive period and in the first weeks of pregnancy (before the pregnancy is confirmed). These aspects may result in epigenetic changes shaping the phenotype of the offspring. The author refers to the Barker's theory of Developmental Origins of Adult Diseases and warns that the above-mentioned health behaviors of women may bring about negative effects for the offspring and future generations, namely susceptibility to chronic diseases: arterial hypertension, obesity type 2 diabetes and metabolic syndrome. Negative effects for the health of offspring may also result from low level of physical activity of women before and during pregnancy The author concludes that it is necessary to intensify the efforts of the Polish Gynecological Society in the area of prenatal public health.

Obesity, hypertension and glucose tolerance disorders have become a growing concern in recent years. It is estimated that over 220 million people suffer from diabetes. It is a condition conducive to cardiovascular diseases, nephropathy, retinopathy and neuropathy but also to the development of many types of cancer. Insulin resistance and hyperinsulinemia lead to increased concentration of insulin-like growth factors, activation of IGF-R receptors, activation of PI3K and Ras-Raf pathways and result in increased cell division. The greatest risk is associated with developing stomach, pancreatic, colorectal, esophageal and lung cancer as well as breast and cervical cancer. Numerous cohort studies have confirmed that diabetic patients treated with metformin show a lower cancer morbidity and mortality rate. The dominant mechanism of action is activation of the AMP-activated protein kinase (AMPK) pathway and inhibition of mTOR protein, the key protein to regulate cell growth, apoptosis, proliferation and protein synthesis. Many clinical trials are currently under way to investigate the effectiveness of metformin in the prevention and treatment of neoplasms.

Poor disease-free and overall survival rates in locally advanced cervical cancer are associated with a tumor micro-environment characterized by extensive hypoxia, interstitial hypertension, and high lactate concentrations. The potential of gadolinium diethylenetriamine pentaacetic acid-based dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in assessing the microenvironment and microenvironment-associated aggressiveness of cervical carcinomas was investigated in this preclinical study. CK-160 and TS-415 cervical carcinoma xenografts were used as tumor models. DCE-MRI was carried out at 1.5 T, and parametric images of K (trans) and v e were produced by pharmacokinetic analysis of the DCE-MRI series. Pimonidazole was used as a marker of hypoxia. A Millar catheter was used to measure tumor interstitial fluid pressure (IFP). The concentrations of glucose, adenosine triphosphate (ATP), and lactate were measured by induced metabolic bioluminescence imaging. High incidence of lymph node metastases was associated with high hypoxic fraction and high lactate concentration in CK-160 tumors and with high IFP and high lactate concentration in TS-415 tumors. Low K (trans) was associated with high hypoxic fraction, low glucose concentration, and high lactate concentration in tumors of both lines and with high incidence of metastases in CK-160 tumors. Associations between v e and microenvironmental parameters or metastatic propensity were not detected in any of the tumor lines. Taken together, this preclinical study suggests that K (trans) is a potentially useful biomarker for poor outcome of treatment in advanced cervical carcinoma. The possibility that K (trans) may be used to identify patients with cervical cancer who are likely to benefit from particularly aggressive treatment merits thorough clinical investigations.

Three-dimensional conformal radiation therapy (3DCRT) has emerged as a preferred treatment for gynecologic malignancies. Yet its superiority to conventional radiotherapy (2-dimensional radiotherapy (2DRT)) for gynecologic malignancies has not been well established. Data from the 2005 to 2010 National Health Insurance Research Database (NHIRD) provided by the National Research Institutes in Taiwan were analyzed to address this issue. Patients were initially diagnosed as having cervical cancer according to the International Classification of Disease, Ninth Revision, Clinical Modification (ICD-9-CM) code 180, and this clinical diagnosis was confirmed histopathologically or cytologically. Kaplan-Meier method and Cox proportional hazards regression were used to analyze the reported data. Between January 2005 and December 2010, there were 776 patients with newly diagnosed cervical cancer without metastasis, local recurrence, or surgical treatment before RT and 132 and 644 patients, respectively, who received 2DRT and 3DCRT. After adjustment for age, diabetes mellitus, hypertension, coronary heart disease, hyperlipidemia, side effects, urbanization level, geographic region, and enrollee category in the 5-year follow-up period, the HR was 1.82 (95% CI, 1.16-2.85, P = 0.009). The 5-year survival rate in the 2DRT and 3DCRT groups was 73.0% and 82.3%, P = 0.007, respectively. Cervical cancer patients treated with 3DCRT had better overall survival.

The burden of disease and public health issues affecting girls and women throughout their lives is significantly greater in resource-poor settings. These women and girls suffer from high rates of maternal mortality, obstetric fistulas, female genital cutting, HIV/AIDS, malaria in pregnancy, and cervical cancer. Although the Millennium Development Goals (MDGs) are being met in some nations, the majority of the goals will not be reached by 2015. In addition, insufficient attention is given to non-communicable and chronic diseases such as diabetes, hypertension, hypercholesterolemia, cardiovascular diseases, stroke, obesity, and chronic respiratory diseases. A life-course approach that includes improvements in earlier-life factors such as diet and exercise is necessary to improve women's long-term health outcomes. Innovative diagnostic tools and treatment strategies along with cost-effective health service delivery systems are needed to make a significant impact on women's and girls' health worldwide.
