Beh?et's disease (BD) with pulmonary arterial aneurysm is rare and often associated with a poor prognosis. But there is also a chance that the aneurysm may completely resolve with medical therapy. A 39-year-old man presented with fever, malaise, bilateral chest pain, recurrent oral ulcers, and hemoptysis. The chest radiograph showed a round opacity in the right hilum. Computed tomography and magnetic resonance angiography (MRA) further revealed multiple, bilateral pulmonary arterial aneurysms consistent with the diagnosis of BD. The patient was started on a course of cyclophosphamide and corticosteroid therapy that resulted in cessation of his symptoms and complete resolution of radiologic findings. The chest radiograph and MRA reverted to normal on long-term follow-up. He is still alive and symptom-free 20 months after diagnosis. 相似文献

Multiple myeloma (MM) is associated with amyloidosis in approximately 15% of the patients. The most frequent presenting signs of such an association are nephrotic syndrome, cardiomyopathy and peripheral neuropathy. Amyloid arthropathy is not a frequent feature. We report a patient with immunoglobulin D (IgD) lambda type MM with presenting symptoms related to mucocutaneous amyloidosis and also amyloid arthropathy. He had no clinical and laboratory involvement due to nephrotic syndrome or cardiomyopathy. IgD myeloma is a rare form of MM and therefore much of the information about the disease is derived from case reports describing patients with associated symptoms. Our case also shows an unusual organ distribution of amyloid. 相似文献

BackgroundRib fractures are the most common complications of blunt chest trauma (BCT). Computed tomography (CT) is the modality of choice for BCT, but with several disadvantages. Ultrasonography (US) is an inexpensive, readily available, and relatively harmless imaging alternative. However, a direct comparison of the sonographic evaluation of the rib as a whole with CT as a reference has not been performed to date.ObjectiveThis study aimed to compare the diagnostic accuracy of US with CT for the detection of rib fractures in patients who presented to emergency department (ED) with BCT.MethodsWe included a convenience sample of adult patients who presented to the ED with thoracic pain after BCT in the last 24 h in this prospective, observational, diagnostic accuracy study. The diagnostic utility of US performed by an emergency physician was compared with thorax CT.ResultsThe final study population included 145 patients. The diagnostic accuracy of US was 80% with a sensitivity of 91.2% and specificity of 72.7% for the detection of any rib fracture (positive likelihood ratio 3.4 and negative likelihood ratio 0.12). If we considered each rib separately, the sensitivity of US decreased to 76.7% and specificity increased to 82.7% (81.3% accuracy).ConclusionsA negative US of the site of the highest tenderness and neighboring ribs in a patient with BCT who presented to the ED with lateralizing pain decreases the possibility of a rib fracture significantly. However, a positive US performs poorly to specify the exact location and number of the fractured ribs. 相似文献

Neuronal degeneration in the post-menopausal term leads to cognitive symptoms such as anxiety, difficulty in concentrating, overreacting to minor upsets, quickly becoming irritated and forgetfulness in approximately 70–80% of all women around the world. These symptoms, which result from microtubule damage in the axon extensions of hippocampal neurons in during menopause, greatly reduce individuals’ life quality. Thus, an investigation of the estrogen receptor-signaling pathway–microtubule dynamic triangle and the possible links between them is important when it comes to explaining the possible mechanism of neurodegeneration. Hematopoietic Pbx-interaction protein (HPIP), a microtubule-binding protein, is a novel scaffolding protein. The detection of this protein on neurons represents the most important step in our hypothesis. The importance of the hypothesis is that it might provide important clues about the possible role of HPIP and its mechanism through in vivo and in vitro studies of estrogen receptors–microtubules and the HPIP triangle in terms of neuronal degeneration in the post-menopausal period. 相似文献

We compared the diagnostic performances of conventional smears and cell block preparations of tissue samples obtained with endobronchial ultrasound-guided transbronchial needle aspiration. We retrospectively analysed 451 patients (926 lymph nodes) who had undergone endobronchial ultrasound and for whom both smears and cell blocks were available and compared the diagnostic performances of these techniques when used alone and combined. Cell block preparations showed higher diagnostic performance over smears, but the combination was superior to either alone. The combination of smear and cell block techniques achieved a sensitivity, specificity and positive and negative predictive values of 92.5, 100, 100, 97.7 and 99.4, 95.0, 98.6, and 97.9 % for malignant and benign diseases, respectively. We recommend cell block preparations during endobronchial ultrasound-guided transbronchial needle aspiration. 相似文献

Malignant kidney neoplasms are the most frequently encountered solid kidney masses. Although renal cell carcinoma is the major renal malignancy, other solid malignant renal masses should be considered in the differential diagnosis of solid renal masses that do not contain a macroscopic fatty component. In this pictorial essay, we present the imaging findings of a primitive neuroectodermal tumor, primary liposarcoma of the kidney, primary neuroendocrine tumor, leiomyosarcoma, synovial sarcoma, malignant fibrous histiocytoma, sclerosing fibrosarcoma and renal metastasis of osteosarcoma. 相似文献
