Abstract:

This study combined phytosanitary surveys, laboratory analyses, and mathematical modeling to show how hail-induced wounds can foster the infections of the blight pathogen Cryphonectria parasitica, locally associated with extensive dieback of chestnut (Castanea sativa). Orchards and coppices located within and outside the assessed dieback area in a single location in the North West of Italy were inspected to appraise the abundance of hail-induced wounds and C. parasitica infections. The incidence of C. parasitica was significantly higher within the dieback area compared with outside (92% versus

Abstract:

Trunk wounds that injure both xylem and phloem can structurally weaken trees, reduce translocation of sap, and provide entry for insects or inoculation sites for disease organisms. Rapid wound closure is beneficial. Illinois data indicate that wound closure is directly related to tree vigor, that large wounds close more in 1 year than small wounds, that wounds less than 12 mm wide are likely to close in 1 year, that annually inflicted wounds less than 25 mm in diameter are not likely to slow tree growth, and that wounds on slow-growing trees close more per unit of radial trunk growth than woun

Sometimes the disease causes serious losses of valuable shade trees. In one outbreak of pin oak blight, diseased trees had a greater rate of decline in increment growth over a 25 yr. period than healthy, uninfected trees. As a result of this growth decline and the remedial pruning needed to remove dead and injured branches, blighted trees had smaller heights and diameters than healthy, uninfected trees.

Recent research suggests that the new systems do not injure tree parts as much as drilling holes, because drilling wounds the tree.

Abstract In Maine and adjacent eastern Canadian provinces, cut-to-length harvesting has emerged as an ecologically attractive method of thinning conifer plantations and natural stands. Yet regional information on the extent of residual stand damage associated with this system is lacking. Eight naturally regenerated red spruce (Picea rubens) stands in northern Maine were studied; all stands were thinned in 1997–1998 with a processor and forwarder combination. Field methods consisted of examining individual trees near forwarder trails for bole damage and measuring the size and aboveground height

Abstract:

Field observations of external wounds associated with two common tree injection methods compared open (plug-less) and sealed (plug) systems in green ash (Fraxinus pennsylvanica Marshall) trees. A wound from any cause within 1.37 m above the ground was common with 28.8% of all trees. The open system had statistically fewer (p < 0.001) trees with at least one wound (11.6% of trees) than the sealed system (47.4% of trees). The open system had fewer (p < 0.001) wounds (0.17, 0.04 SE) per tree and a smaller (p < 0.001) total wound area (25.5 cm2, 8.7 SE) per tree, compared to the sealed sy

Our objective was to determine the influence of several clinical factors on the survival of patients with penetrating wounds to the heart. A retrospective review of 80 consecutive penetrating cardiac injuries treated in a Level II urban trauma center from 1980 through 1994 were examined. Thirty-six patients (45%) had gunshot wounds (including 1 shotgun wound), and 44 (55%) had stab wounds. Intervention consisted of emergency room (ER) or operating room thoracotomy. We measured the effect of several clinical factors on morbidity and patient survival. Survival rate was 17 of 36 (47%) in gunshot

Abstract:

Branches were pruned from 10 species of trees by the "Shigo" and the conventional methods. The branches (four per tree, five trees per species) averaged 50 to 75 mm (2 to 3 in) in diameter. Wounds from conventional cuts were 30 to 50 percent larger than wounds from Shigo cuts. There was little closure of Shigo wounds during the first year. After four years, the conventional wounds were smaller than the Shigo wounds on six species, approximately the same size on one species, and larger on three species.

The amount of trunk growth on ten species of plantation-grown trees differed among and between species. Wound closure rates on these trees correlated positively with trunk growth and varied between species and between years. More callus was produced around large wounds than around small wounds on the same tree. Callus growth at the periphery of the wound was greater than the radial growth of the stem. Closure rate on slow-growing trees within a species was greater per unit of radial growth than on the fast-growing trees. Significant variability in wound closure rates was found within a populat

Abstract:

Many trees have the genetic potential to wall off wound-induced wood discoloration from moving into their interiors. These trees actually build walls, mainly of phenolic compounds, that retard the spread of microorganisms. To build these walls, they use carbohydrate reserves from their sapwood parenchyma cells interior to the wound. New wounds that breach old walls of strong-compartmentalizing trees, or wounds that intrude into discolored areas of weak-compartmentalizing trees expose areas depleted of carbohydrate content. Here strong new walls cannot be built. The amount of decay resulting fr

The reason for the interest in the problem of facial and maxillofacial injuries (CJS) is the increase in the number of injuries to the tissue structures of the face and brain, which is characterized by uncertainty of consequences and difficulty of treatment outcome. Occurrence of neurological deficits in the post-injury period disrupts patients’ social adjustment. The serious consequences of acute joint facial injuries make it one of the social problems of national and global importance.

Oropharyngeal injuries are commonly seen in practice. Severity can range from minor to life threatening in the case of dorsal pharyngeal or oesophageal punctures. A prompt diagnosis and early aggressive surgical management may be required to prevent the development of mediastinitis and sepsis. This article will look at acute injuries and outline a systematic approach to these cases, enabling the clinician to make early decisions rather than adopting a ‘wait and see’ approach.

Mortality (26%) was concentrated in seedlings less than 75 cm tall and was not related to damage. Surviving trees recovered from most wounds within the 6-year period. In most cases, lateral branches turned up to replace broken terminal leaders or stems; bole wounds healed over; and trees that had been pushed over returned to an upright position. A combina

Despite major advances in the operative management of penetrating colon wounds, there remains discussion regarding the appropriate treatment of destructive colon injuries, with a significant amount of scientific evidence supporting segmental resection with primary anastomosis in most patients without comorbidities or large transfusion requirement. Although literature is sparse concerning the management of blunt colon injuries, some studies have shown operative decision based on
