Roentgenologic diagnosis of primary corticotropin-producing carcinoid tumors of the mediastinum

A study was undertaken of five patients with Cushing syndrome due to adrenocorticotropin (ACTH) production by thymic carcinoid tumor (primary mediastinal APUDomas), including two recent patients examined by computed tomography (CT) of the chest. Plain roentgenography of the chest initially failed to detect tumor in four of the five patients, while CT of the chest yielded definitive diagnostic information in both patients in whom it was employed. For one of these patients, a mediastinal tumor could be seen retrospectively on plain roentgenograms of the chest, although it had been missed on the first examination. One of the tumors appeared to be partially calcified on CT scan, a finding not previously reported. Blastic osseous metastasis, which is common when malignant carcinoid tumors spread to bone, was seen in one patient. Our data suggest that in patients with suspected ectopic ACTH production, CT scanning of the mediastinum should be performed early in order to avoid delay in diagnosis of an ACTH-secreting carcinoid tumor of the mediastinum.     

Towards better child protection programmes: a qualitative evaluation of Youth Disseminating Life Skills Programme

The present study aimed to assess the acceptability of a 12-week training programme, Youth Disseminating Life Skills Programme whose aims were to help university students acquire knowledge on and to increase sensitivity towards child abuse and neglect by adopting a qualitative methodology. The sample consisted of 13 university students who took part in the Youth Disseminating Life Skills Programme (10 female, 3 male: mean age 22 years; age range: 20–31). With the help of a general interview guide, the focus group meetings were held. Established conventions guided the analysis. Participants recounted feelings about and benefits of the Programme, and ways to improve the Programme. Feelings about the Programme included both positive (e.g. feeling hopeful) and negative feelings (e.g. feeling traumatised). Participants recounted a variety of benefits of the Programme (e.g. correcting some myths about child abuse). Participants proposed some ways whereby the Programme could be improved. Some findings could be interpreted in terms of existing literature/theory. Other findings extended the literature and could be viewed as targets for future child protection programmes.

Endometrial damage and apoptosis in rats induced by dichlorvos and ameliorating effect of antioxidant vitamins E and C

We aimed to investigate the effect of subchronic administration of dichlorvos (DDVP) on endometrium and to evaluate ameliorating effects of a combination of Vitamins E and C against DDVP toxicity in the rat. Three groups of rats were used in the experiment. The first group was treated with 4 mg/kg DDVP; the second group was treated with 4 mg/kg body weight DDVP plus Vitamins E and C (DDVP + Vit); the third group was given only corn oil (control). DDVP and DDVP + Vit groups were given DDVP by gavage 5 days a week for 4 weeks at a dose level of 4 mg/kg day by using corn oil as the vechicle. Vitamins E and C were injected at doses of 50 mg/kg i.m. and 20 mg/kg body weight i.p. Histopathological and immunohistochemical examinations for caspase-3 and caspase-9 were accomplished in the endometrium. The level of malondialdehyde (MDA) increased significantly in the DDVP group compared with the control group (p < 0.05). MDA significantly decreased in the DDVP + Vit group compared with the DDVP group (p < 0.05). Administration of Vitamins E and C along with DDVP significantly reduced the histopathological changes and the extent of apoptosis. In conclusion, subchronic DDVP administration caused endometrial damage and that treatment with a combination of Vitamins E and C reduced endometrial damage caused by DDVP.     

Seroepidemiological Study of Human Hydatidosis in Meshkinshahr District,Ardabil Province,Iran

Background

The aim of this study was to conduct a sero-epidemiological survey in Meshkinshahr, Ardabil Province, northwestern Iran to detect the rate of hydatidosis in the city and nearby villages. Literature shows that no such study has been conducted so far.

Methods

Overall, 670 serum samples were collected from 194 males and 476 females from patients referred to different health centers of the region. All patients filled out a questionnaire and an informed consent. Sera were analyzed using indirect-ELISA test. Ten µg /ml antigens (Antigen B derived from hydatid cyst fluid), serum dilutions of 1:500 and conjugate anti-human coombs with 1:10000 dilutions were utilized to perform the test. Data analysis was conducted using SPSS software ver. 11.5.

Results

The seroprevalence of human hydatidosis was 1.79% by ELISA test in the region. This rate for females was 1.68% and males 2.6%, respectively. There was no significant difference as regards all factors studied and the seropositivity. According to job, farmers and ranchmen had the highest rate of infection as 3.17%. The sero-prevalence of infection was 2.6%% in illiterate people which showed the highest rate. As regards residency, urban life showed no significant difference with rural life (1.1% vs. 2.58%). Age group of 69–90 yr old, with 4.62% as prevalence had the highest rate of positivity.

Conclusion

Obtained sero-prevalence of hydatidosis shows more or less a resemblance to other cities of Iran, although due to the specific condition of the city we expected more rate of sero-positivity.     

Superoxide Dismutase (SOD) Enzyme Activity Assay in Fasciola spp. Parasites and Liver Tissue Extract

Background

The purpose of this comparative study was to detect superoxide dismutase (SOD) activities in Fasciola hepatica, F. gigantica parasites, infected and healthy liver tissues in order to determine of species effects and liver infection on SODs activity level.

Methods

Fasciola spp. parasites and sheep liver tissues (healthy and infected liver tissues), 10 samples for each, were collected, homogenized and investigated for protein measurement, protein detection and SOD enzyme activity assay. Protein concentration was measured by Bradford method and SODs band protein was detected on SDS-PAGE. SODs activity was determined by iodonitrotetrazolium chloride, INT, and xanthine substrates. Independent samples t-test was conducted for analysis of SODs activities difference.

Results

Protein concentration means were detected for F. hepatica 1.3 mg/ ml, F. gigantica 2.9 mg/ml, healthy liver tissue 5.5 mg/ml and infected liver tissue 1.6 mg/ml (with similar weight sample mass). Specific enzyme activities in the samples were obtained 0.58, 0.57, 0.51, 1.43 U/mg for F. hepatica, F. gigantica, healthy liver and infected liver respectively. Gel electrophoresis of Fasciola spp. and sheep liver tissue extracts revealed a band protein with MW of 60 kDa. The statistical analysis revealed significant difference between SOD activities of Fasciola species and also between SOD activity of liver tissues (P<.05).

Conclusion

Fasciola species and liver infection are effective causes on SOD enzyme activity level.     

Genetic contributions to pain: a review of findings in humans

Pain represents the major motivating factor for which individuals seek healthcare, and pain responses are characterized by substantial inter‐individual differences. Increasing evidence suggests that genetic factors contribute significantly to individual differences in responses to both clinical and experimental pain. The purpose of this review article was to summarize the current literature regarding genetic contributions to pain, highlighting findings relevant to oral pain where available. A brief discussion of methodologic considerations is followed by a review of findings regarding genetic influences on clinical pain. Next, the literature examining genetic contributions to experimental pain responses is presented, emphasizing genetic associations that have been replicated in multiple cohorts. It is hoped that an enhanced understanding of genetic contributions to pain responses will ultimately improve diagnosis and treatment of clinical pain conditions.

Serum IL-8 and IL-12 levels in breast cancer

Interleukins (ILs) are known to play a fundamental role in cancer. We investigated the serum levels of IL-8 and IL-12, in breast cancer patients, and their relationship with the prognostic parameters and therapy. Fortyeight patients with pathologically verified breast carcinoma and 21 healthy controls were enrolled into the study. Serum samples were obtained at baseline and after two cycles of chemotherapy. Serum IL-8 and IL-12 levels were determined using enzyme-linked immunosorbent assay (ELISA). There was no significant difference in the baseline serum IL-8 and IL-12 levels between breast cancer patients and healthy controls (p = 0.365 andp = 0.871, respectively), no significant correlation between the prognostic parameters and the serum IL-8, IL-12 levels. However, in the subgroup consisting of metastatic breast cancer patients, baseline serum IL-8 levels were significantly higher compared with non-metastatic disease (p = 0.047). Anthracycline-based chemotherapy and the addition of taxane did not change the levels of both serum IL-8 and IL-12. Serum IL-8 level may be useful in determining metastatic breast cancer. Larger studies are needed to confirm this finding.
