The development of the intestinal microbiota in the first years of life is a dynamic process significantly influenced by early‐life nutrition. Pioneer bacteria colonizing the infant intestinal tract and the gradual diversification to a stable climax ecosystem plays a crucial role in establishing host–microbe interactions essential for optimal symbiosis. This colonization process and establishment of symbiosis may profoundly influence health throughout life. Recent developments in microbiologic cultivation‐independent methods allow a detailed view of the key players and factors involved in this process and may further elucidate their roles in a healthy gut and immune maturation. Aberrant patterns may lead to identifying key microbial signatures involved in developing immunologic diseases into adulthood, such as asthma and atopic diseases. The central role of early‐life nutrition in the developmental human microbiota, immunity, and metabolism offers promising strategies for prevention and treatment of such diseases. This review provides an overview of the development of the intestinal microbiota, its bidirectional relationship with the immune system, and its role in impacting health and disease, with emphasis on allergy, in early life. 相似文献

Nasal hyperreactivity is one of the most important underlying mechanisms in both allergic (AR) and idiopathic rhinitis (IR).
In order to study the pathomorphological changes in this entity, tissue samples from patients with AR, IR, and from patients
without chronic inflammation were taken during nasal surgery. Primary antibodies against Substance P (SP), calcitonin gene-related
peptide (CGRP), and endothelial nitric oxide synthases (NOS III) were applied and the immunocomplexes were visualized by immunocytochemistry.
The nasal mucosa of patients with AR and IR showed similarities on the ultrastructural level. Neurogenic inflammation was
indicated by a strong innervation pattern with sensory nerve fibers containing SP and CGRP. We could show that extensive edema
and cellular infiltration might be characteristic for AR. On other hand there was no evidence of eosinophilic or NO involvement
in IR. Finally, on the ultrastructural level, AR and IR showed many similarities. Based on these findings anti-inflammatory
therapy modalities could be recommended for both types of rhinitis.
This study was presented at the XXVII EAACI Congress, June 7–11, 2008, in Barcelona, Spain. 相似文献

Primary ciliary dyskinesia syndrome (PCD) is a rare, autosomal receive disorder. Kartagener's syndrome is a subgroup of the PCD with situs inversus, bronchiectasis, and sinusitis. The symptoms results from an abnormal ultrastructural morphology of the cilia such as absence of dynein arms and other changes. As a consequence ciliary motility is disturbed. A 25-year-old man was examined because he suffered from recurrent severe pneumonia and Aspergillus infections of the lungs. On electron micrographs, ciliary abnormalities including deficiency of inner and outer dynein arms, dysmorphic outer dynein arms, and disorientation of the cilia were demonstrated. The diagnosis of PCD requires electron-microscopic investigations of the ciliated mucosa. Special attention should be given to ultrastructural changes of nasal or bronchial mucosa if a young patient suffers from recurrent severe respiratory infections. 相似文献

Extracranial meningiomas are rare tumors of the lateral skull base. A 37-year-old woman presented with tinnitus und progressive hearing loss of her right ear. A painful mass lesion was also palpable in her mandibular angle. CT and MRI scans revealed an intracranial mass with extension to the lateral skull base. These findings suggested the occurrence of a paraganglioma or meningioma. In a two-stage surgical procedure tumor was extirpated without functional impairment to the patient. Histology of the excised lesion demonstrated an endotheliomatous meningioma. Since an extracranial meningioma can present as a mass lesion of the lateral skull base, CT and MRI scans are essential in preoperative surgical planning. 相似文献
