Abstract
General interest in the biological functions of IFN type I in Mycobacterium tuberculosis (Mtb) infection increased after the recent identification of a distinct IFN gene expression signature in tuberculosis (TB) patients. Here, we demonstrate that TB-susceptible mice lacking the receptor for IFN I (IFNAR1) were protected from death upon aerogenic infection with Mtb. Using this experimental model to mimic primary progressive pulmonary TB, we dissected the immune processes affected by IFN I. IFNAR1 signaling did not affect T-cell responses, but markedly altered migration of inflammatory monocytes and neutrophils to the lung. This process was orchestrated by IFNAR1 expressed on both immune and tissue-resident radioresistant cells. IFNAR1-driven TB susceptibility was initiated by augmented Mtb replication and in situ death events, along with CXCL5/CXCL1-driven accumulation of neutrophils in alveoli, followed by the discrete compartmentalization of Mtb in lung phagocytes. Early depletion of neutrophils rescued TB-susceptible mice to levels observed in mice lacking IFNAR1. We conclude that IFN I alters early innate events at the site of Mtb invasion leading to fatal immunopathology. These data furnish a mechanistic explanation for the detrimental role of IFN I in pulmonary TB and form a basis for understanding the complex roles of IFN I in chronic inflammation.

Abstract
The molecular mechanisms that control innate immune cell trafficking during chronic infection and inflammation, such as in tuberculosis (TB), are incompletely understood. During active TB, myeloid cells infiltrate the lung and sustain local inflammation. While the chemoattractants that orchestrate these processes are increasingly recognized, the posttranscriptional events that dictate their availability are unclear. We identified microRNA-223 (miR-223) as an upregulated small noncoding RNA in blood and lung parenchyma of TB patients and during murine TB. Deletion of miR-223 rendered TB-resistant mice highly susceptible to acute lung infection. The lethality of miR-223(–/–) mice was apparently not due to defects in antimycobacterial T cell responses. Exacerbated TB in miR-223(–/–) animals could be partially reversed by neutralization of CXCL2, CCL3, and IL-6, by mAb depletion of neutrophils, and by genetic deletion of Cxcr2. We found that miR-223 controlled lung recruitment of myeloid cells, and consequently, neutrophil-driven lethal inflammation. We conclude that miR-223 directly targets the chemoattractants CXCL2, CCL3, and IL-6 in myeloid cells. Our study not only reveals an essential role for a single miRNA in TB, it also identifies new targets for, and assigns biological functions to, miR-223. By regulating leukocyte chemotaxis via chemoattractants, miR-223 is critical for the control of TB and potentially other chronic inflammatory diseases.

Abstract
Tuberculosis causes 2 million deaths per year, yet in most cases the immune response successfully contains the infection and prevents disease outbreak. Induced lymphoid structures associated with pulmonary granuloma are observed during tuberculosis in both humans and mice and could orchestrate host defense. To investigate whether granuloma perform lymphoid functions, mice lacking secondary lymphoid organs (SLO) were infected with Mycobacterium tuberculosis (MTB). As in WT mice, granuloma developed, exponential growth of MTB was controlled, and antigen-specific T-cell responses including memory T cells were generated in the absence of SLO. Moreover, adoptively transferred T cells were primed locally in lungs in a granuloma-dependent manner. T-cell activation was delayed in the absence of SLO, but resulted in a normal development program including protective subsets and functional recall responses that protected mice against secondary MTB infection. Our data demonstrate that protective immune responses can be generated independently of SLO during MTB infection and implicate local pulmonary T-cell priming as a mechanism contributing to host defense.

Abstract
OBJECTIVES Ultrasonography (US), computed tomography (CT) and magnetic resonance imaging (MRI) are the most common radiological procedures for the diagnosis of tumor-like lesions of the salivary glands. The aim of the present study was to determine whether MRI or CT provide additional information besides that delivered by US. STUDY DESIGN/METHODS 109 patients with a tumor-like lesion of the salivary glands underwent surgery. MRI and CT were arranged in 73 and in 40 patients respectively, whereas all 109 patients were prospectively diagnosed by US. The results of CT, MRI and US were compared with the histological outcome. Furthermore, the recent rise in the number of CT and MRI studies was investigated. RESULTS On CT and MRI, there was no rise in the percentage of malignant tumors or advanced surgical procedures. In respect of the radiological assessment of the lesion (benign/malignant) and the correct diagnosis, CT, MRI and US were comparable in terms of sensitivity, specificity and accuracy. No significant difference was found in the Chi-square test (p > 0.05). CONCLUSION The evaluation of the preoperative results of CT, MRI and US revealed no advantage for CT or MRI; these procedures are only required in specific cases. An update or revision of the current preoperative diagnostic management is deemed necessary.

Abstract
Myxoid chondrosarcomas of the head and neck region are rare. We report the case of an 8-year-old boy with progressive unilateral nasal obstruction resulting from a highly differentiated myxoid chondrosarcoma of the maxilla extending to the nasal cavity and the ethmoid. Clinical presentation, histological findings and therapy are presented with a brief review of the literature. This case reaffirms the importance of considering sarcomas or other neoplastic lesions in the differential diagnosis of progressive nasal obstruction in children.

Abstract
BACKGROUND In 90% of all cases, Mycobacterium tuberculosis infection results in latency rather than active disease, with the pathogen being contained within granulomatous lesions at the site of primary infection. Failure of this containment leads to reactivation of postprimary tuberculosis (TB). The regional immune processes that sustain the delicate balance with persistent M. tuberculosis, however, remain unclear. METHODS We compared activation statuses, biological functions, and interactions of host immune cells in human nonprogressive tuberculoma and active cavitary tuberculous lung tissue. RESULTS Dissection of early granuloma formations revealed differential cellular distribution and activation statuses of distinct cell types in different regions relative to the central caseotic caverna or the tuberculoma in tuberculous lung tissue. In patients with tuberculoma with latent infection, distant parts of lung tissue exhibited strong vascularization and profound proliferative activity, indicating that continuous immune defense is required for mycobacterial containment, which is absent in cavitary tuberculous lung lesions. CONCLUSIONS We conclude that differential regulation of the local immune response is crucial for the containment of M. tuberculosis and that a continuous antigen-specific cross talk between the host immune system and M. tuberculosis is ensured during latency. This activation requires sufficient supply of nutrients and well-coordinated structural organization, both of which are lost during reactivation of TB.

Abstract
The human tuberculous granuloma provides the morphological basis for local immune processes central to the outcome of tuberculosis. Because of the scarcity of information in human patients, the aim of the present study was to gain insights into the functional and structural properties of infiltrated tissue. To this end, the mycobacterial load in lesions and dissemination to different tissue locations were investigated, as well as distribution, biological functions, and interactions of host immune cells. Analysis of early granuloma formation in formerly healthy lung tissue revealed a spatio-temporal sequence of cellular infiltration to sites of mycobacterial infection. A general structure of the developing granuloma was identified, comprising an inner cell layer with few CD8(+) cells surrounding the necrotic centre and an outer area of lymphocyte infiltration harbouring mycobacteria-containing antigen-presenting cells as well as CD4(+), CD8(+), and B cells in active follicle-like centres resembling secondary lymphoid organs. It is concluded that the follicular structures in the peripheral rim of granulomas serve as a morphological substrate for the orchestration of the enduring host response in pulmonary tuberculosis.

Abstract
To gain an insight into the mechanisms of chronic and acute inflammation, the production of neutrophil chemokines in different types of tonsillitis - hyperplastic tonsillitis (HT), recurrent tonsillitis (RT) and peritonsillar abscesses (PA) - was investigated. The chemokines interleukin-8 (IL-8), growth-related oncogene-alpha (GRO-alpha), epithelial cell-derived neutrophil attractant-78 (ENA-78) and granulocyte chemotactic protein-2 (GCP-2) were detected and shown to have different biological activities. With respect to the biological properties of CXC chemokines, the biological activity of the chemokines was identified using a three-step high-performance liquid chromatography (HPLC) technique, a bioassay involving measurement of neutrophil chemotaxis in a single Boyden chamber in tissue of HT, RT and PA. Using reverse transcription-polymerase chain reaction (RT-PCR), the chemokine concentrations were determined in the different tonsillitis entities. The chemokine pattern was dominated in PA by IL-8 and GRO-alpha and in RT by GRO-alpha. Hyperplastic tonsils of patients without a history of infection generated about five times lower IL-8 than PA. A protein concentration of GCP-2 was induced in PA and RT, whereas ENA-78 remained the same in all entities. In conclusion, it would appear that IL-8 was up-regulated in acute inflammation, whereas GRO-alpha dominated in chronic inflammation. ENA-78 seems not to play a pivotal role in inflammatory processes in tonsils. GCP-2 may serve as a substitute chemokine in certain inflammatory conditions as its quantity of mRNA and protein was higher in RT and PA than in HT.

Abstract
Ziehl-Neelsen (ZN) staining is the key technique for diagnosis of mycobacterial infections; however, a high percentage of patients exhibit positive signs of tuberculosis, as indicated by pathology, culture of mycobacteria, and polymerase chain-reaction analysis, and yet show negative results on ZN staining. In this report we present evidence that such ZN-negative specimens represent Mycobacterium tuberculosis bacilli in a dormant state with distinct cell-wall alterations: the classical cell-wall composition-dependent ZN staining of M. tuberculosis in lung sections gradually discontinued with persistence of infection, both in mice and in human patients; in contrast, detection of mycobacteria by cell-wall composition-independent staining using a polyclonal anti-M. bovis Bacille-Calmette-Guérin serum continued with persistence of infection. These findings have important implications for diagnosis, as well as for both chemotherapy and development of vaccine strategies.'

Abstract
BACKGROUND AND METHODS Allergic rhinitis is a very common disease with an increasing prevalence to 10-20% over the last 40 years. These studies propose different reasons for this increase. RESULTS An increasing exposure to outdoor allergens is shown in different geographical and climatic areas, like the rising frequency of reactions to cockroaches in Europe or to mites in tropical areas. New aero-allergens have appeared in the animal and vegetable realms, both in home and professional environments. Respiratory allergy to Ficus benjamina inaugurated a new type of allergy caused by airborne allergens from non-pollinating plants. This is specially important because of the cross-reactions to latex. CONCLUSION The immunochemical structures of airborne allergens are now better known, and the homologous structures of different allergens largely explain certain cross-reactions. In the future, recombinant allergens will probably lead to better understanding of the role of allergens in inducing and maintaining the allergic reaction and should promote our approach to diagnosis and therapy.
