Eosinophilic lung diseases are a diverse group of pulmonary disorders with an extensive list of differential diagnoses. Multiple drugs particularly antibiotics can cause pulmonary eosinophilia with variable pulmonary manifestations. Cutaneous drug reactions are common. Diagnosis is usually made on clinical history and blood eosinophilia with an accumulation of eosinophils in alveolar spaces on histologic analysis. Imaging findings are nonspecific. Stopping the offending agent is often enough while a short course of corticosteroids can hasten recovery...

Coccidioidomycosis is usually acquired by inhalation of spores of Coccidioides immitis and C. posadasii. The disease ranges from a self-limited acute pneumonia (Valley Fever) to a disseminated disease. We present a 44-year-old healthy male who had patchy hair loss of several months duration resembling discoid lupus. He developed a firm non-scaly red plaque on the right forehead. Initial biopsy showed spongiotic dermatitis, and he was treated with systemic steroids. He then developed forehead and periorbital cellulitis and was treated with systemic antibiotics...

A 57-year-old woman with SAPHO (synovitis-acne-pustulosis-hyperostosis-osteitis) syndrome presented with recurrent episodes of pneumonia. She was treated with multiple courses of antibiotics with no success. The transbronchial biopsy undertaken via bronchoscopy revealed organising pneumonia (OP). She was treated with steroids and responded well with full clinical recovery and normalisation of her chest X-ray.To our knowledge, this is the first reported case of OP in association with SAPHO syndrome. This case report highlights the importance of considering OP in patients with SAPHO syndrome who present with chest infection...

The lung develops an unique epithelial barrier system to protect host from continuous invasion of various harmful particles. Interleukin (IL-)33 released from epithelial cells in the lung drives the type 2 immune response by activating ST2- expressed immune cells in various allergic diseases. However, the involvement of memory-type ST2(+)CD4(+) T cells in such lung inflammation remains unclear. Here we demonstrated that intratracheal administration of IL-33 resulted in the substantial increase of numbers of tissue-resident memory-type ST2(+)CD4(+) T cells in the lung...

AIMS: Carbapenem-resistant Klebsiella pneumoniae (CRKP) infection has been rapidly emerging as a life-threatening nosocomial disease in many countries. However, studies on the corresponding risk factors of CRKP infection showed inconsistent results. To resolve these inconsistencies, we conducted a meta-analysis of previous studies on the potential risk factors of CRKP infection. The results of this study could be used to develop CRKP infection prevention strategies. METHODS: Relevant works were systematically searched from five electronic databases up to September 2016...

Traci N Adams, Yasmeen M Butt, Kiran Batra, Craig S Glazer
Cobalt exposure in the hard metal and bonded diamond tool industry is a well-established cause of ILD. The primary theories regarding the underlying mechanism of cobalt related ILD include an immunologic mechanism and an oxidant injury mechanism. Cobalt related ILD may present in subacute and chronic forms and often has associated upper respiratory symptoms. The evaluation begins with a thorough occupational history and includes PFTs, HRCT, and bronchoalveolar lavage. HRCT findings are nonspecific and may resemble NSIP, UIP, sarcoidosis, or HP...

BACKGROUND: Allo-immune mediated lung syndromes (allo-LS) are life-threatening complications after hematopoietic cell transplantation (HCT). Respiratory virus (RV) has been suggested to play a role in the pathogenesis. OBJECTIVE: We studied the relation between RV-DNA/RNA detection in upper/lower airway before HCT and the occurrence of allo-LS. METHODS: We retrospectively analyzed all HCT recipients between 2004 and 2014, in whom Real-Time PCR for RV was done from Nasal-Pharyngeal-Aspirates (NPA) and Broncho-Alveolar- Lavage (BAL) before HCT...

BACKGROUND: The beneficial effect of macrolides for the treatment of community-acquired pneumonia (CAP) in combination with beta-lactams may be due to their anti-inflammatory activity. In patients with pneumococcal meningitis, the use of steroids improves outcomes only if they are administered before beta-lactams. The objective of this study was to compare outcomes in hospitalized patients with CAP when macrolides were administered before, simultaneously with, or after beta-lactams. METHODS: Secondary data analysis of the Community-Acquired Pneumonia Organization (CAPO) International Cohort Study database...
