Prevotella bivia is associated with pelvic inflammatory disease. A 77-year-old man developed a rapidly growing chest wall abscess due to P. bivia within days. He underwent surgical resection of the infected area; his postoperative course was uneventful. This is the first
case of chest wall abscess due to P. bivia infection. Its correct diagnosis cannot be underestimated because fulminant infections can occur in aged or immunocompromised
patients if treated incorrectly. Prompt, appropriate surgical management, and antibiotic therapy affect treatment outcome.

The occurrence, bleeding, and treatment of internal mammary artery (IMA) injury after blunt chest trauma have not been well described in the literature. We reviewed articles published from July 1977 to February 2014 describing IMA injury after blunt chest trauma in 49 patients. There was a predominant incidence in males and on the left side. Blunt trauma to the IMA can cause anterior mediastinal hematoma, hemothorax, pseudoaneurysm, arteriovenous fistula, and extra-pleural hematoma. Of the 49 patients studied, 20 underwent embolization, 22 underwent surgical operation, 4 were managed by clinical observation, and 3 had undescribed treatment. Different parts and extents of IMA injury, adjacent vein injury, as well as the integrity of the pleura determined differences in bleeding modality. Prompt diagnosis, complete hemostasis, aggressive resuscitation, and multidisciplinary teams are recommended for patients with IMA injury. 相似文献

针对激光选区熔化成形倾斜薄壁件尺寸精度低、成形质量差等问题,应用响应曲面法研究工艺参数及倾斜角度对薄壁件壁厚的影响,建立倾斜角度、工艺参数与壁厚相对误差关系模型。结果表明:倾斜角度对壁厚的影响最大,激光功率次之。由于倾斜角度改变,薄壁件悬垂面粉末支撑区域不同,导热效果存在差异,激光功率与扫描间距对于不同倾斜角度的薄壁件壁厚影响不同。其中,激光功率对45°倾斜薄壁件壁厚的影响最大,当激光功率选择150~350W时,壁厚相对误差最大差值为24%而扫描间距对90°倾斜薄壁件壁厚的影响最大,当扫描间距选择0.1~0.2mm时,壁厚相对误差最大差值为9.5%,合理的工艺参数能够有效降低壁厚相对误差。 相似文献

Didactic and laboratory anatomical education have seen significant reductions in the medical school curriculum due, in part, to the current shift from basic science to more clinically based teaching in North American medical schools. In order to increase medical student exposure to anatomy, with clinical applicability, a student-run initiative called surgically oriented anatomy prosectors (SOAP) club was created within the extracurricular program at the Schulich School of Medicine and Dentistry, The University of Western Ontario, London, Canada. SOAP invites surgeons and residents from various surgical specialties to demonstrate, on a cadaver, a surgical procedure of their choosing. During the demonstration, the anatomy, as it relates to the surgical procedure, is discussed. The students then break into smaller groups to examine the relevant anatomy on the cadavers, during which time the discussion is broadened. The group continues the conversation in a social environment with refreshments. SOAP is one of the most popular extracurricular clubs with 65% of first and second year medical students registered as members. The high demand for SOAP, along with the positive participant feedback, may be due to its utilization of the principle of education through recreation, which seeks to provide opportunities for learning seamlessly throughout all facets of life. It also demonstrates the desire, amongst certain medical students, to learn applied anatomy, particularly within a surgical context. 相似文献

OBJECTIVE: To evaluate the utility of oblique chest views in the diagnosis of rib fractures when used as a routine part of the skeletal survey performed for possible physical abuse. METHODS: Oblique chest views have been part of the routine skeletal survey protocol at Primary Children's Medical Center since October 2002. Dictated radiology reports since that time were reviewed, and all cases with rib fractures documented were chosen for study. For each chosen case two pediatric radiologists identified and recorded rib fractures using only the PA and lateral chest radiographs (standard two-view chest series) from the skeletal survey for each case. In a separate session they identified and recorded rib fractures using the PA, lateral, right oblique, and left oblique radiographs (four-view chest series) from the skeletal survey for each case. The results were compared. RESULTS: Twenty-two cases with rib fractures were identified. Interpretation of the four-view chest series was different than interpretation of the two-view chest series in 12 of the 22 cases (54%). Overall, the four-view chest series differed significantly in the number of rib fractures diagnosed compared with the two-view chest series (p=.02, Wilcoxon matched-pairs signed-rank test) adding 19 rib fractures and excluding 6 rib fractures. CONCLUSIONS: The results indicate that use of the four-view chest series adds information to that obtained from the two-view chest series and increases the accuracy of diagnosing rib fractures in cases of possible physical abuse. Addition of oblique chest views to the routine protocol for skeletal surveys performed for possible physical abuse is recommended. 相似文献

Primary spontaneous pneumothorax (PSP) commonly occurs in tall, thin, adolescent men. Though the pathogenesis of PSP has been
gradually uncovered, there is still a lack of consensus in the diagnostic approach and treatment strategies for this disorder.
Herein, the literature is reviewed concerning mechanisms and personal clinical experience with PSP. The chest computed tomography
(CT) has been more commonly used than before to help understand the pathogenesis of PSP and plan further management strategies.
The development of video-assisted thoracoscopic surgery (VATS) has changed the profiles of management strategies of PSP due
to its minimal invasiveness and high effectiveness for patients with these diseases. 相似文献

Numerical study of heat transfer characteristics of downward supercritical kerosene flow inside circular tubes 总被引：3，自引：0，他引：3
The heat transfer characteristics of China RP-3 aviation kerosene flowing in a vertical downward tube with an inner diameter of 4 mm under supercritical pressures are numerically studied. A ten-species surrogate model is used to calculate the thermophysical properties of kerosene and the re-normalization group (RNG) k-ε turbulent model with the enhanced wall treatment is adopted to consider the turbulent effect. The effects of mass flow rate, wall heat flux, inlet temperature, and pressure on heat transfer are investigated. The numerical results show that three types of heat transfer deterioration exist for the aviation kerosene flow. The first type of deterioration occurred at the tube inlet region and is caused by the development of the thermal boundary layer, while the other two types are observed when the inner wall temperature or the bulk fuel temperature approaches the pseudo-critical temperature. The heat transfer coefficient increases with the increasing mass flow rate and the decreasing wall heat flux, while the inlet bulk fluid temperature only influences the starting point of the heat transfer coefficient curve plotted against the bulk fluid temperature. The increase of inlet pressure can effectively eliminate the deterioration due to the small variations of properties near the pseudo-critical point at relatively high pressure. The numerical heat transfer coefficients fit well with the empirical correlations, especially at higher pressures (about 5 MPa). 相似文献
