Nipple Sign, A Stigmata of Recent Arteriovenous Malformation Bleed in the Bronchial Tree
Hemoptysis is defined as expectoration of blood originating from the lower respiratory tract (i.e., below the vocal cords). Among the potential sources of bleeding from the bronchial tree are arteriovenous malformations (AVMs). Although pulmonary AVM and its diagnostic imaging features have been well described, less is known about bronchial AVM. This report describes an elderly man with multiple AVMs in his gastrointestinal tract who was admitted with hemoptysis and found to have AVM in his bronchial tree
Using the EBUS Scope in the Esophagus
This chapter aims at introducing the interested Pulmonologist/Interventional Pulmonologist to the esophageal ultrasound. In this chapter, we give short descriptions of some technical aspects of the endobronchial ultrasound (EBUS) scope and explain in detail why we believe the EBUS scope is well suited to be an esophageal scope in the hands of the trained pulmonologist. The chapter then explains indications and benefits of this procedure that we consider central to the practice of chest physicians. We also describe in steps how to reach each lymph node station using the EBUS scope as a EUS scope (EUS-B) from our own experience. Procedurerelated complications and contraindications are also described

Isolated Candida infection of the lung
AbstractCandida pneumonia is a rare infection of the lungs, with the majority of cases occurring secondary to hematological dissemination of Candida organisms from a distant site, usually the gastrointestinal tract or skin. We report a case of a 77-year-old male who is life-long smoker with a history of rheumatoid arthritis and polymyalgia rheumatica, but did not take immunosuppressants for those conditions. Here, we present an extremely rare case of isolated pulmonary parenchymal Candida infection in the form pulmonary nodules without evidence of systemic disease which has only been described in a few previous reports
Esophageal diagnosis of a malignant aspergilloma
A 59-year-old male patient developed a new 4 cm × 6 cm cavitary left upper lung lesion over a 2 months period. The patient had a prior history of a surgically resected Stage IA non-small cell lung cancer in the right upper lobe 3 years prior. He was treated for possible infection with radiographic improvement on subsequent imaging. Further imaging after 3 months revealed an oval soft tissue density within the cavity with air crescent sign. Bronchoscopy with transbronchial biopsies showed an acute and chronic granulomatous inflammation. Aspergillus fumigatus was noted on culture and voriconazole was initiated. Subsequent imaging showed initial improvement and then the stability of cavity size. However, 11 months later, the medial wall of the cavity showed increased thickness. Bronchoscopy showed no endobronchial lesions. Esophageal ultrasound-guided fine-needle aspiration using the endobronchial curvilinear endoscopic ultrasound bronchoscope was performed for a sampling of the cavity wall that was abutting the mediastinum. The aspirate showed squamous cell lung cancer and the patient was started on therapy after appropriate staging
MRSA induced pulmonary-renal syndrome
We present a rare case of pulmonary-renal syndrome secondary to recurrent MRSA spondylodiscitis. The mechanism of involvement of each organ system is unique. The organs, lung and kidneys, have been affected by different pathologic processes that were induced, we think, by the chronic MRSA infection
Bronchopleural Fistula Resolution with Endobronchial Valve Placement and Liberation from Mechanical Ventilation in Acute Respiratory Distress Syndrome: A Case Series
Patients who have acute respiratory distress syndrome (ARDS) with persistent air leaks have worse outcomes. Endobronchial valves (EBV) are frequently deployed after pulmonary resection in noncritically ill patients to reduce and eliminate bronchopleural fistulas (BPFs) with persistent air leak (PAL). Information regarding EBV placement in mechanically ventilated patients with ARDS and high volume persistent air leaks is rare and limited to case reports. We describe three cases where EBV placement facilitated endotracheal extubation in patients with severe respiratory failure on prolonged mechanical ventilation with BPFs. In each case, EBV placement led to immediate resolution of PAL. We believe endobronchial valve placement is a safe method treating persistent air leak with severe respiratory failure and may reduce days on mechanical ventilation
Severe Pneumomediastinum Complicating EBUS-TBNA
Pneumomediastinum infrequently complicates diagnostic bronchoscopy. Increased airway or alveolar pressure results in air leaks to the mediastinum through existing or induced defects. Excessive cough, recurrent episodes of increased abdominal pressure, vomiting, or sneezing can all induce spontaneous pneumomediastinum. Less commonly it has been documented with lung or neck infections, esophageal or tracheal tears, and rapid increases in altitude such as during plane flights or scuba diving, with mechanical ventilation, substance abuse, and after bronchoscopy. Pneumomediastinum may be, but is not always, associated with pneumothorax
Pneumonia due to a Rare Pathogen: Achromobacter xylosoxidans, Subspecies denitrificans
Achromobacter xylosoxidans, subspecies denitrificans, is a gram-negative rod recently implicated as an emerging cause of infection in both immunosuppressed and immunocompetent populations. Few cases are reported in literature involvingmultiple body systems. Diagnosis depends on cultures of appropriate specimens, and management usually is by administration of appropriate antibiotics(usually agents with antipseudomonal activity).We report a rare case of pneumonia due to infection with this organism, in a patient with preexisting bronchiectasis secondary to chronic aspiration
Is chest tube insertion with ultrasound guidance safe in patients using clopidogrel?
Background and objective: Drainage of the pleural space is a common procedure.The safety of chest tube insertion in patients using clopidogrel has not been investigated.
Methods: Ultrasound-guided chest tube insertions performed on 24 patients who were being actively treated with clopidogrel were retrospectively reviewed.
Results: No excessive bleeding occurred in any of these patients.
Conclusions: Given the known effects of clopidogrel on platelet function, these results were interpreted as indicating that clopidogrel therapy is a relative but not an absolute contraindication to chest tube insertion, if an experienced operator places a small-bore tube under ultrasound guidance
