Frequency of various types of neoplasia in a group of acromegalic patients

OBJECTIVE: To determine the frequency of colon cancer, primary hyperparathyroidism, thyroid tumor, and skin cancer in all acromegalic patients in follow-up at the Clinics Hospital - Botucatu Medical School, from 2005 to 2011. SUBJECTS AND METHODS: These patients were evaluated retrospectively for colon cancer, primary hyperparathyroidism, dermatological, and thyroid tumors. RESULTS: Of 29 patients included at the beginning of the study, two were excluded. Among 19 patients submitted to colonoscopy, one presented colon adenocarcinoma (5%). Thyroid nodules were present in 63% of patients, and papilliferous carcinoma was confirmed in two patients (7,7%). Four patients were confirmed as having primary hyperparathyroidism (15%). The most common dermatologic lesions were thickened skin (100%), acrochordons (64%), epidermal cysts (50%), and pseudo-acanthosis nigricans (50%). Only one patient presented basal cell carcinoma. CONCLUSION: Although a small number of acromegalic patients was studied, our findings confirm the high frequency of thyroid neoplasias and primary hyperparathyroidism in this group of patients.

Resorption of roots of different dimension induced by different types of forces

Root resorption is a variable to be considered in induced tooth movement (ITM). It is related to root morphology and alveolar bone crest, and also to the types of forces exerted by mechanotherapy. This histometric study evaluated the predominance of root resorption among roots of different dimensions, following ITM with different types of forces and at different time intervals. The study was conducted on 54 rats divided into three groups, according to the type of force: continuous (CF), continuous interrupted (CIF) and intermittent (IF), at periods of 5, 7 and 9 days. The percentage of resorption between mesiobuccal roots of larger dimension and intermediate roots of smaller dimension was assessed. The evaluations were performed on the AxioVision software, and the non-parametric analysis of variance for repeated measures in independent groups was further applied, consisting of a scheme of two factors, and complemented by the Dunn test at a significance level of 5%. The intermediate roots presented a higher percentage of resorption, which was gradual at the periods evaluated for the three types of forces, but mainly for CF. Comparing the intermediate roots with the mesiobuccal roots, there was a statistically significant difference (p < 0.05) in the CF group at day 7 and day 9, and in the FI group, at day 9. The intragroup analysis evidenced a statistically significant difference (p < 0.05) between the 5th and the 9th day for the intermediate root in the CF group. The intergroup analysis did not reveal any statistically significant difference (p > 0.05) in individually analyzed roots.

Cultivation of Agaricus blazei in the environmental protection area of the Baturité region under three types of casing soils

The outdoor cultivation (ditches) of Agaricus blazei was evaluated in the protected natural area (APA) of the mountainous region of Baturité on three types of casing soils (A, B and C). Casing soil A (horizon A) of the local soil was used (Alfisol). Casing B was obtained with a mixture of 30% of eucalyptus charcoal (1-2 cm of length) and 70% of horizon B of the local soil. Casing C was composed of 25% of vermiculite, 25% of coconut fiber and 50% of coarse sand. Temperature, relative humidity and pluviometric rates were monitored. The physical-chemical properties of the three casing soils were analyzed. The effect of the casing soil on the number and weight of the mushrooms, productivity, yield and biological efficiency of A. blazei were evaluated. The yield, productivity, biological efficiency and number of mushrooms were higher when using soil A. The highest productivity for soil A was attributed mainly to the physical characteristics, which were considered more appropriate for the cultivation, in addition to the high pluviometric rates and relative humidity. The productivity with soil A (9.62%) is comparable with the average productivity obtained in Brazil, meaning that the cultivation of A. blazei in this APA may have good perspectives for cultivation.

Interference of Vaccinal Antibodies on Serological Diagnostic of Leptospirosis in Vaccinated Buffalo using Two Types of Commercial Vaccines

The vaccinal antibodies interference represents one of the problems in the leptospirosis diagnostic on serum. The present study aimed to determine the pattern of serum agglutinins anti-Leptospirae spp in vaccinated female buffaloes against leptospirosis using two types of commercial vaccines: bacterin and extern membrane. The temporal interference of vaccinal titers on serum diagnostic was evaluated. Three groups of 11 adult female buffaloes were established as follows: G1 control, non-vaccinated; G2: vaccinated with bacterin containing six serovars and G3 with extern membrane vaccine containing five serovars. A booster was administered at 30 days from the first vaccination (dfv) and two re- vaccinations were performed in each semester (days 210 and 390). Serum samples were collected on days 0, 15, 30, 45 and 60 and every 30 days until 540 dfv, being submitted to Serum Agglutination Microscopy (SAM) against the serovars present in the vaccine. G1 remained always negative. Both vaccines induced serologic responses when assessed by SAM at 150 days post first vaccination against all serovars and they revealed maximum titers around days 45 and 60 after first vaccination. At the re-vaccination there was an increase on agglutinin levels, but of less intensity than the levels previously observed. After six months from the second revaccination (540 dfv), they were almost zero, which demonstrates the short duration of diagnostic interference. The serologic monitoring of the vaccinated herds can be an efficient method to evaluate the status of protection provided by the vaccine.

Technical and economic evaluation of different types of control of Brevipalpus phoenicis (Acari: Tenuipalpidae) in citrus leprosies management

The objective of this work was to evaluate the effect of acaricide applications and pruning of symptomatic branches in citrus leprosis management in Brazil. It was conducted in an orange plantation of the 'Pera' variety, grafted onto the 'Cleopatra' tangerine, in two seasons (2006-2007 and 2007-2008). The experimental design was randomized blocks in a factorial scheme consisting of the following factors: (A) acaricide, in three levels: spirodiclofen and cyhexatin applied in rotation, lime sulphur; no acaricides; (B) pruning to remove branches that showed symptoms of leprosis, with two levels: with pruning, without pruning. We carried out periodic assessments of Brevipalpus phoenicis (Geijskes) populations (vector of the leprosis virus), leprosis incidence and severity, fruit yield, and the economic feasibility of the applied strategies. Based on the results, we concluded that spirodiclofen and cyhexatin were more effective than lime sulphur in B. phoenicis control. Control with lime sulphur required more applications than spirodiclofen and cyhexatin in rotation, making it more expensive. Pruning of symptomatic branches used in isolation was not sufficiently effective to control leprosis and significantly increased control costs. Profits were higher when the control involved sprayings of spirodiclofen and cyhexatin in alternation, with or without pruning.

Effects of short-term immersion and brushing with different denture cleansers on the roughness, hardness, and color of two types of acrylic resin

Purpose: To investigate the cumulative effects of brushing (B) or immersion (I), using different cleansing agents, on the surface roughness, hardness and color stability of a heat-polymerized denture resin, Lucitone 550 (L), and a hard chairside reline resin, Tokuyama Rebase Fast II (T). Methods: A total of 316 specimens (10 x 2 mm) were fabricated. The specimens (n= 9) were divided into brushing or immersion groups according to the following agents: dentifrice/distilled water (D), 1% sodium hypochlorite (Na0C1), Corega Tabs (Pb), 1% chlorhexidine gluconate (Chx), and 0.2% peracetic acid (Ac). Brushing and immersion were tested independently. Assays were performed after 1, 3, 21, 45 and 90 blushing cycles or immersion of 10 seconds each. Data were evaluated statistically by repeated measures ANOVA. Tukey's honestly significant difference (HSD) post-hoc test was used to determine differences between means (a= 0.05). Results: For L there was no statistically significant difference in roughness, except a significant decrease in roughness by brushing with D. T showed a significant effect on the roughness after 90 immersions with Ac. Hardness values decreased for L when specimens were immersed or brushed in Na0C1 and Pb. The hardness of T decreased with increases in the repetitions (immersion or brushing), regardless of the cleaning method. Values of color stability for L resin showed significant color change after brushing with and immersion in Ac and Pb. Brushing with D exhibited a higher incidence of color change. For T there were no significant differences between cleaning agents and repetitions in immersion. A color change was noted after three brushings with the Ac, Chx, and D. Brushing with dentifrice decreased roughness of L. Immersion in or brushing with Na0C1 and Pb decreased the hardness of L. For T, hardness decreased with increases in immersions or brushing. Color changes after the immersion in or brushing with cleaning agents were clinically acceptable according to National Bureau of Standards parameters for both resins.
