Incomplete mandibular fracture after lateralization of the inferior alveolar nerve for implant placement

PURPOSE: The present case describes an inferior alveolar nerve lateralization for implant placement that caused mandible fracture a few days after surgery. CLINICAL REPORT: In this case, a 56-year-old female patient who had a severely atrophied jaw and showing bone height less than 7 mm from the bone crest and the mandibular canal was submitted to surgery lateralization of the inferior alveolar conducted with piezzo. Even with all postoperative care, the patient suffered an incomplete fracture of the mandible a few days after lateralization of the inferior alveolar nerve for implant placement. The patient was treated with soft diet and medications for pain and antibiotics, besides removing the implant associated with the fracture. CONCLUSION: It is suggested that this procedure may be conducted in 2 operative periods: firstly, the lateralization of the inferior alveolar; and secondly, after a period of 3 months, the implant placement in a situation of more bone stability.

Anatomia radicial de Mormodes sinuata Rchb. f. & Warm.; (Catasetinae, Cymbidieae: Orchidaceae)

Since there is a lack of information on the root organization of the sub-tribe Catasetinae, current research describes the anatomy of Mormodes sinuata roots and indicate adaptations related to water provision and other taxonomical traits. Five roots of three plants, cut at the median region with a blade, were fixed and preserved in alcohol 5%. Cuts were stained by saffron blue 0.05% and mounted in glycerin. Although the roots have structural characteristics adapted to epiphytism, some anatomic characteristics demonstrate that the species requires more watering or wetter environments when compared with other types of Catasetinae. Root anatomic characteristics foreground results by authors who include the sub-tribe Catasetinae within the tribe Cymbidieae. Further, anatomic characteristics have a generic uniformity and are a tool for the genus's systematics.

Evolução de pacientes com AIDS pós cART: Evolução clínica e laboratorial de pacientes com AIDS após 48 semanas de tratamento antirretroviral

Combination Antiretroviral Therapy (cART) aims to inhibit viral replication, delay immunodeficiency progression and improve survival in AIDS patients. The objective of this study was to compare two different schemes of cART, based on plasma viral load (VL) and CD4+ T lymphocyte count, during 48 weeks of treatment. For this purpose, 472 medical charts of a Specialized Outpatient Service were reviewed from 1998 to 2005. Out of these, 58 AIDS patients who had received a triple drug scheme as the initial treatment were included in the study and two groups were formed: Group 1 (G1): 47 individuals treated with two nucleoside reverse-transcriptase inhibitors (NRTI) and one non-nucleoside reverse-transcriptase inhibitor; Group 2 (G2): 11 patients treated with two NRTI and one protease inhibitor. In G1 and G2, 53.2% and 81.8% respectively were patients with an AIDS-defining disease. The T CD4+ lymphocyte count increased progressively up until the 24th week of treatment in all patients, while VL became undetectable in 68.1% of G1 and in 63.6% of G2. The study concluded that the evolutions of laboratory tests were similar in the two treatment groups and that both presented a favorable clinical evolution.

Teores de iodo em dietas secas e úmidas para gatos adultos comercializadas na cidade do Rio de Janeiro, Brasil

Were analyzed 29 samples, 16 wet and 13 dry cat food of different flavors. The iodine levels ranged from 2.7 to 3.4 (average 2.95 mg/kg/MS) in dry food and 2.9 to 4.0 (average 3.4 mg/kg/MS) in the wet food. Eight samples (27.6%) specified on the package the assurance level (maximum) of iodine, with a dry (2.0 mg/kg/diet) and seven wet (0.04 mg/kg/diet). All non-compliant, because the values were higher than declared. Cats fed commercial diets consume proportionally more iodine in wet food than cats fed dry diets, but both with high levels of iodine. All samples analyzed were above the amounts stated on the labels. Accordingly, the wet and dry commercial food for cats show no reliable values with those reported, resulting in a possible excessive intake of this trace element for animals in question.

Características agronômicas do feijão caupi inoculado em função de lâminas de irrigação e de níveis de nitrogênio

The aim of this study was to evaluate the effect of different irrigation depths and nitrogen levels on the agronomic characteristics of inoculated cowpea. The experiment was arranged in splitplots, with the levels of nitrogen in the plots and the depth of irrigation in the splitplots, in a randomized block design, with two repetitions. The irrigation depth corresponded to 578 mm (L1), 512 mm (L2), 429 mm (L3), 299 mm (L4) and 240 mm (L5), and the nitrogen levels of 0, 30, 60 and 90 kg ha-1 of N. The nitrogen levels showed significant effect on the yield components of cowpea. The irrigation depth showed significant effects on productivity of bean cowpea, with the depth of 426.21 mm estimated for obtaining the maximum productivity of 2820.03 kg ha-1.

Quality of performance of the operation of sugarcane mechanized planting in day and night shifts

The sugarcane mechanized planting is becoming increasingly widespread in Brazil due to a higher operability and better working conditions offered to workers compared to other types of planting. Studies related to this topic are insufficient or scarce in Brazil. In this context, the aim of this study was to evaluate the operation quality of sugarcane mechanized planting in two operation shifts, by means of statistical process control. The mechanized planting was held on March 2012 and statistical design was completely randomized with two treatments, totaling 40 replications for the day shift and 40 replications for the night shift. The variables evaluated were: speed, engine rotation, engine oil pressure, water temperature of the engine, effective field capacity and the time consumption hourly and effective fuel. The use of statistical control charts showed that random intrinsic do not cause this process. The tractor alignment error showed outliers in the day and night shifts operations, indicating a possible delay in receiving the signal. The water temperature of the engine and the effective fuel consumption showed lower variability in nighttime operation with average values of 81°C and 22.66 L ha-1, respectively. The hourly fuel consumption had greater variability and consequently lower quality during the night of the operation, with an average consumption of 25.46 L h-1 while the day shift showed 26.86 L h-1.

Horizontal ridge augmentation of the atrophic anterior maxilla using rhBMP-2/ACS or autogenous bone grafts: A proof-of-concept randomized clinical trial

Aim To compare the effect of recombinant human bone morphogenetic protein-2 (rhBMP-2) in an absorbable collagen sponge carrier (ACS) with autogenous bone graft for augmentation of the edentulous atrophic anterior maxilla. Methods Twenty-four subjects were enrolled in a randomized, controlled, parallel-group, open-label clinical trial. Subjects either received rhBMP-2/ACS (1.5 mg/ml) or particulated autogenous bone harvested from the mandibular retromolar region. A titanium-mesh was used to provide space and wound stability. A guide was used to standardize clinical recordings using an analogue caliper. Alveolar ridge width was also assessed using cone-beam computed tomography. Results rhBMP-2/ACS yielded significantly greater radiographic horizontal bone gain compared with autogenous bone graft at immediate subcrestal levels (1.5 ± 0.7 versus 0.5 ± 0.9 mm; p = 0.01); non-significant differences were observed at mid- (2.9 ± 0.8 versus 2.9 ± 0.9 mm; p = 0.98) and apical (1.7 ± 0.9 versus 1.8 ± 1.1 mm; p = 0.85) crestal levels. No significant differences in clinical horizontal bone gain were observed at 6 months between rhBMP-2/ACS and autogenous bone graft (3.2 ± 0.9 mm versus 3.7 ± 1.4 mm; p = 0.31). Sixty-two implants were placed after 6 month of healing with no significant differences between groups for number of implants, implant size, primary stability and survival. Conclusions rhBMP-2/ACS appears a realistic alternative for augmentation of the edentulous atrophic anterior maxilla. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Produtividade e perdas de amendoim em cinco diferentes datas de arranquio

The harvest is a critical time in the production of the peanut (Arachis hypogaea L.), however in this operation losses are inevitable, in some cases o f up to 30% of production. Peanuts are grown for a short period during the reform of the sugarcane fields, providing better usage of the agricultural spaces in Jaboticabal, São Paulo. The objective of this research was to see how early the peanuts could be dug up once they are seen to have matured. The peanuts were dug up at 120, 125, 130, 135 and 140 days after sowing. Results were subjected to variance analysis by the F-test, and when there was significance of the averages, the Tukey test at 5% probability was applied, using a box plot for the following variables: maturation, moisture content of pods and soil, mechanical resistance of soil to penetration, harvest loss and productivity. The box plot proved efficient in the univariate evaluation of the analyzed variables, creating excellent conditions for viewing their behavior. Digging up the peanuts at 120 DAS is recommended.
