International Journal of Clinical Medicine (IJCM) , 2013, DOI: 10.4236/ijcm.2013.412A1005
Abstract:

Background: Basosquamous carcinoma (BSC) is a rare non-melanoma skin cancer, considered to be a subtype of basal cell carcinoma (BCC). BSC often produces distant metastases with a higher risk of recurrence than that of BCC which is not commonly found in the lip. Case Report: A 57-year-old white female patient presented an ulcer on her lower lip that had an ongoing development for over six months. Physical examination, photo documentation, videoroscopy, scraped cytology, toluidine blue test, and biopsy of the ulcer were carried out. Results: Upon physical examination we observed an actinic cheilitis associated with the ulcer. Videoroscopy revealed the presence of fissures and erosion that had not been seen by oroscopy. Toluidine blue test was only positive for the region of the ulcer. Cytological analysis revealed rare nests compatible with carcinoma. Histopathology of the biopsy revealed a carcinoma with nests lined by basal cells associated with areas of squamous differentiation. The patient was then referred to surgery for the removal of the BCC. Analysis of the specimen showed free surgical margins and the immunohistochemical panel did not confirm the initial diagnosis of BCC, indicating a subtype of BSC. After surgery, the patient has been followed by periodic consultations. She is well and without further complications. Coments: BSC

Abstract: Background: Patients with rheumatic diseases have profound alterations in the immune system as a result of underlying diseases and the treatments used, which increases the risk of occurrence and severity of infections, including enteroparasitosis. The current treatment for rheumatoid arthritis involves immunosuppressive therapies powerfully needed for screening infectious processes. The prevalence of parasitic infections in rheumatoid arthritis patients is not currently documented in literature. The objective of the current study was to determine the prevalence of parasitic diseases in a population with RA. Methods: We collected demographic and socioeconomic data from 67 patients at the Hospital Universitário de Brasília from July 2015 to April 2016. All patients underwent a parasitological examination of their stool and multiple variables were analyzed using Poisson regression method. Results: The mean age of patients was 53.9 years. They were predominantly in women (94%) and caucasian (47.8%). The mean disease duration was 9.2 years and most patients had the disease in remission or light activity. The prevalence of parasitic infections in these patients was 11.9%, all cases being that of protozoa of the following species: Endolimax nana, Entamoeba histolytica and Entamoeba coli. The final multivariate analysis indicated that the presence of disease had a significant statistical relationship between the presence of enteroparasitosis and rheumatoid arthritis with no fatigue by VAS (p = 0.0488) and best current health index by VAS (p = 0.0012). Conclusion: This study indicates that the prevalence of enteroparasitoses in a population with Rheumatoid Arthritis was 11.9% and all cases were found of protozoa.

Abstract: Background Low birth weight (LBW) is associated with an increased risk of mortality, adverse metabolic conditions, and long-term chronic morbidities. The relationship between LWB and short maternal stature coupled with nutritional status was investigated in poor communities. Methods/Principal Findings A cross-sectional population-based study involving 2226 mother-child pairs was conducted during the period 2009-2010 in shantytowns of Maceió, Alagoas, Brazil. Associations between LBW and maternal sociodemographics, stature and nutritional status were investigated. The outcome variable was birth weight (< 2500g and ≥ 2500g). The independent variables were the age, income, educational background, stature and nutritional status (eutrophic, underweight, overweight and obese) of the mother. The frequency of LBW was 10%. Short-statured mothers (1st quartile of stature ≤ 152cm) showed a tendency of increased risk of LBW children compared to mothers in the 4th quartile of stature (>160.4cm) (OR: 1.42, 95% CI: 0.96 - 1.09, p = 0.078). Children from short-statured mothers weighed an average of 125g less than those from taller mothers (3.18±0.56kg vs. 3.30±0.58kg, respectively p = 0.002). Multivariate analyses showed that short stature, age < 20y (OR: 3.05, 95% CI:1.44 - 6.47) or were underweight (OR: 2.26, 95% CI:0.92 - 5.95) increased the risk of LBW, while overweight (OR: 0.38, 95% CI:0.16 - 0.95) and obesity (OR: 0.39, 95% CI:0.11 - 1.31) had lower risk for LBW. In taller mothers, lower income and underweight were associated with LBW (OR: 1.88, 95% CI: 1.07 - 3.29 and 2.85, 95% CI:1.09 - 7.47, respectively), and obese mothers showed a trend of increased risk of LBW (OR: 1.66, 95% CI:0.84 - 3.25). Conclusions/Significance Overweight was found to have a protective effect in short-statured mothers, indicating that a surplus of energy may diminish the risk of LBW. Short-statured younger mothers, but not taller ones, showed higher risk of LBW. The mother being underweight, regardless of stature, was associated with LBW.

Abstract: chromosome numbers for four species of anthurium and four species of philodendron from bahia, brazil, were determined. new counts 2n = 30 for a. longipes and a. affine, 2n = 32 for p. pedatum and 2n = 34 p. blanchetianum and p. pachyphyllum represent the first reports for these species. the 2n = 32 found for p. imbe and 2n = 90 for a. bellum differ from earlier reports, whereas 2n = 30 and 60 for a. pentaphyllum var. pentaphyllum confirms previous counts. a. affine had one to four b-chromosomes. we suggest secondary base numbers x = 15 for anthurium and x = 16, 17 and 18 for philodendron, produced by hybridizations and duplications involving the primary base numbers x = 7, 8 and 9.

Abstract: structure of intertidal and subtidal benthic macrofauna in the northeastern region of todos os santos bay (tsb), northeast brazil, was investigated during a period of two years. relationships with environmental parameters were studied through uni-and multivariate statistical analyses, and the main distributional patterns shown to be especially related to sediment type and content of organic fractions (carbon, nitrogen, phosphorus), on both temporal and spatial scales. polychaete annelids accounted for more than 70% of the total fauna and showed low densities, species richness and diversity, except for the area situated on the reef banks. these banks constitute a peculiar environment in relation to the rest of the region by having coarse sediments poor in organic matter and rich in biodetritic carbonates besides an abundant and diverse fauna. the intertidal region and the shallower area nearer to the oil refinery rlam, with sediments composed mainly of fine sand, seem to constitute an unstable system with few highly dominant species, such as armandia polyophthalma and laeonereis acuta. in the other regions of tsb, where muddy bottoms predominated, densities and diversity were low, especially in the stations near the refinery. here the lowest values of the biological indicators occurred together with the highest organic compound content. in addition, the nearest sites (stations 4 and 7) were sometimes azoic. the adjacent caboto, considered as a control area at first, presented low density but intermediate values of species diversity, which indicates a less disturbed environment in relation to the pelitic infralittoral in front of the refinery. the results of the ordination analyses evidenced five homogeneous groups of stations (intertidal; reef banks; pelitic infralittoral; mixed sediments; caboto) with different specific patterns, a fact which seems to be mainly related to granulometry and chemical sediment characteristics.
