O consórcio de culturas é prática comum na maioria das pequenas propriedades do Brasil, sendo grande parte do milho e feijão produzidos são provenientes de cultivo em consórcio. Este trabalho foi desenvolvido durante dois anos, objetivando avaliar a eficiência produtiva do milho em consórcio com o feijão, utilizando diferentes populações de plantas em relação ao monocultivo, em solo originalmente com vegetação de cerrado e, anteriormente, cultivado com arroz. O delineamento experimental foi em blocos ao acaso com quatro repetições. Com exceção das diferenças observadas entre os cultivares, onde o cultivar de milho BR-201 sobressaiu em relação ao cultivar Tractor, o consórcio não interferiu nas características agronômicas do milho. A população de 50.000 plantas ha -1 apresentou maiores valores para as características agronômicas do milho.

This research work was conducted for three years aiming at evaluating the effect of sidedressing nitrogen application (0, 25, 50, 75, and 100 kg ha-1) on winter bean crop under different systems of soil management (conventional, minimal, and no-tillage systems). The experimental design was a randomized block arranged in strips relative to tillage systems, with random distribution of nitrogen doses into each strip, with four replications. Grain yield was affected by nitrogen rates and significant increases were obtained with the application of 75 to 100 kg N ha-1. Soil management did not affect grain yield, although the "minimum system" provided better results in the two first years.

O consórcio de culturas é prática comum na maioria das pequenas propriedades no Brasil e parte do milho e do feijão produzidos são provenientes de cultivos em consórcio. O trabalho foi desenvolvido durante dois anos agrícolas, objetivando avaliar a eficiência do feijão em consórcio com milho, utilizando diferentes populações de plantas em relação ao monocultivo. O delineamento experimental utilizado foi em blocos ao acaso com quatro repetições. O consórcio interferiu em todas as características agronômicas do feijoeiro, das quais a mais afetada foi o número de vagens planta -1 e as menos afetadas o número de grãos vagem -1 e a massa de 100 grãos. A população de 125.000 plantas ha -1 de feijão produziu mais na menor população de milho (30.000 plantas ha -1 ), já a população de 250.000 plantas ha -1 de feijão resistiu mais ao consórcio e se desenvolveu bem nas duas populações de milho (30.000 e 50.000 plantas ha -1 ).

Desse modo, propôs-se este estudo com o objetivo de avaliar diferentes fontes e épocas de aplicação de N em trigo cultivado no sistema plantio direto. O delineamento experimental utilizado foi o de blocos ao acaso disposto em um esquema fatorial 2x6 com quatro repetições. Os tratamentos foram constituídos pela combinação de duas fontes de N: uréia e Entec e seis épocas de aplicação: testemunha (sem N); N na semeadura (S); N 15 dias após a emergência (DAE); N aos 30 DAE; 1/3 do N na S e 2/3 aos 15 DAE; e 1/3 do N na S e 2/3 aos 30 DAE. O experimento foi realizado na área experimental da UNESP - Campus de Ilha Solteira, localizada no município de Selvíria - MS, em solo anteriormente ocupado por vegetação de Cerrado. O N aplicado 30 dias após a emergência propiciou maior produtividade de grãos, entretanto não diferindo estatisticamente da aplicação com 1/3 do N na semeadura + 2/3 do N 30 dias após a emergência.

The experiment was carried out in Selvíria-MS, during the agricultural year of 2006/07. Application of 150 g ha-1 of trinexapac-ethyl in Primavera rice cultivar at panicle initiation differentiation reduces plants height, 0.40 m on average comparing to other times, with lodging absence. Trinexapac-ethyl promotes lange number of abnormal grains, reduction of grain yields in doses above 150 g ha-1, when applied in panicle initiation differentiation stadium. Application of 150 g ha-1 of trinexapac-ethyl at any time does not interfere in crop yield.

A total number of 32 individuals were positive for Schistosoma mansoni. Results of stool examinations revealed individual S. mansoni egg counts per gram of faeces (epg) ranging from 4-768 epg with a geometric mean egg count of 45. The most frequent clinical symptoms were abdominal pain (78.1%), headache (75%), fever (65.6%), dry cough (65.2%) and both diarrhoea and asthenia (59.4%). A malacological survey of the area, where 22 specimens of Biomphalaria glabrata were collected, revealed three (13.6%) specimens eliminating Schistosoma cercariae. This investigation re-confirms a recently described pattern of schistosomiasis infection, resulting in the acute form of the disease and connected to rural tourism, which contributes to the spread of the disease among the middle-class and into non-endemic areas. The lack of specific knowledge about acute schistosomiasis among health services causes an increased number of unnecessary diagnostic procedures and delays in accurate diagnosis and treatment, resulting in considerable discomfort for the patients.

O povoamento de pinus possui quarenta anos de idade, já sofreu desbastes, e apresenta uma densidade de cerca de 890 arv./ha. A metodologia iniciou-se com a coleta de dados de forma tradicional e com o equipamento ILRIS-3D (OPTECH). Com o auxilio de GPS geodésico e estação total determinou-se coordenadas de alvos na fl oresta que serviram de base para georreferenciamento do scanner. A varredura foi realizada em um giro de 360 graus com resoluções de 10 mm e 50 mm a 50 metros em dois pontos distintos do povoamento. Os dados da varredura foram processados com o intuito de isolar e fi l trar uma árvore. Como resultado, chegou-se a um bom isolamento de árvores e fi ltragem de pontos, obteve-se ainda a altura total de 31,93 metros e alturas parciais em intervalos de 1 metro relativas a uma árvore do povoamento. A tecnologia laser scanner terrestre apresenta potencial 86 promissor para área fl orestal abrangendo a aplicação em inventários fl o restais, planejamento de manejo, produção e colheita fl orestal.

We report the updated results of Video Endoscopic Inguinal Lymphadenectomy (VEIL), an original minimally invasive procedure recently reported for extended inguinal node dissection in clinical settings. Patients and Methods: Fifteen consecutive patients who underwent the VEIL technique were prospectively followed and included in this study. The first 10 patients underwent bilateral inguinal dissection for nonpalpable lymph nodes: VEIL at one side and standard open lymph node dissection at the other side. A second cohort consisted of five patients who underwent bilateral VEIL, either for nonpalpable or for palpable (N1) inguinal nodes. Operative data and postoperative outcomes were assessed, and VEIL and the open technique were compared. Results: Twenty limbs underwent VEIL and 10 limbs underwent the open procedure. Mean operative time was 120 minutes for VEIL and 92 minutes for the open procedure. There was no difference in the number of nodes removed or in the positivity for metastatic lymph nodes. Complications were observed in 70% of limbs that underwent open surgery and in 20% of limbs that underwent VEIL (P ϭ 0.015). Patients who underwent a bilateral VEIL could be discharged from the hospital after an average of 24 hours (range 12-36 hrs), while patients who underwent an open dissection in addition to contralateral VEIL were discharged after an average of 6.4 days (range 5-10 d) There were no recurrences detected during a mean follow-up of 31.9 months (median 33 months). Conclusion: This preliminary series suggests that VEIL can reduce morbidity, including hospitalization times, compared with standard open surgery. Oncologic results are premature but seem similar to the results from the conventional open operation. VEIL is a promising minimally invasive approach for radical inguinal dissection in penile cancer patients with nonpalpable or low-volume palpable inguinal disease.

A 42-year-old woman had undergone external beam radiotherapy for squamous cell carcinoma of the cervix and developed a vesicovaginal fistula with small capacity bladder. Intraoperative option for urinary diversion was colonic conduit. A 4 trocar transperitoneal approach was chosen and isolation of both ureters was performed. A 5 cm incision between xiphoid and umbilicus was carried out. A 15 cm colonic segment was isolated with linear stapler maintaining blood supply. Intestinal transit was then reconstructed. Leadbetter ureterointestinal anastomoses were performed with ureteral splints. Drainage, colostomy maturation, and closure of incisions were carried out conventionally. Operative time was 195 minutes; blood loss was 90 mL; no intraoperative or postoperative complications were observed. Length of hospital stay was 7 days and time to full recovery 3 weeks. Video-assisted colonic conduit is feasible and have promising results concerning reduction of surgical morbidity.

However, it may rarely be related to explosion precipitated by the contact of the electrocautery with some gases produced during the resections. The authors present a case of vesical explosion, discuss its mechanism and suggest some measures for prevention. A 71-years-old male underwent TURP and hemostasy of bleeding from the bladder neck due to persistent hematuria. A wire loop electrode set at a cutting and coagulating current of 80 watts was used. During coagulation of a bleeding in the anterior aspect of the vesical neck when the bladder was empty, a loud pop was heard and a jolt was felt at the lower abdomen. Inspection revealed a hole in the dome of the bladder with loops of small bowel visible. A low midline incision was done, and the intraperitoneal bladder rupture was repaired. Although uncommon, vesical explosion during TURP may occur and some preventive measures, discussed herein, can be performed to avoid this complication.
