RATIONALE AND OBJECTIVES: To assess the nature of the satisfaction of search (SOS) effect in chest radiography when observers are fatigued; determine if we could replicate recent findings that have documented the nature of the SOS effect to be due to a threshold shift rather than a change in diagnostic accuracy as in earlier film-based studies. MATERIALS AND METHODS: Nearing or at the end of a clinical workday, 20 radiologists read 64 chest images twice, once with and once without the addition of a simulated pulmonary nodule...

BACKGROUND: Our study was designed to improve the accuracy of determining whether pulmonary nodules are benign or malignant. METHODS: We evaluated the clinical and imaging features and serum markers: neuron specific enolase (NSE), carcino-embryonic antigen (CEA), cytokeratin fragment antigen 21-1 (CYFRA 21-1), miRNA-21-5p, and miR-574-5pof in 39 patients with pathology information. Factors that differed significantly between those with benign versus malignant pulmonary nodules were used to establish a prediction model for identifying malignant nodules...

It is estimated that over 1.5 million lung nodules are detected annually in the United States. Most of these are benign but frequently undergo invasive and costly procedures to rule out malignancy. A risk predictor that can accurately differentiate benign and malignant lung nodules could be used to more efficiently route benign lung nodules to non-invasive observation by CT surveillance and route malignant lung nodules to invasive procedures. The majority of risk predictors developed to date are based exclusively on clinical risk factors, imaging technology or molecular markers...

In resource-limited countries, the diagnosis of pulmonary tuberculosis (TB) is based on clinical findings, chest radiography and the demonstration of acid-fast bacilli in sputum. Few data are available on the use of ultrasound (US) to diagnose pulmonary TB. Chest US was performed in patients with lung TB from a rural African setting, to look for signs of the disease and to clarify the role US may have in the diagnosis of pulmonary TB. Sixty adult patients diagnosed with lung TB underwent chest US. All patients had abnormal findings...

REVIEW
Siddharth Yadav, Prabhjot Singh, Ashok Hemal, Rajeev Kumar
Genitourinary Tuberculosis (GUTB) is the second most common extra-pulmonary manifestation of tuberculosis (Tb) and an isolated involvement of genital organs is reported in 5-30% of the cases. Genital involvement results from primary reactivation of latent bacilli either in the epididymis or the prostate or by secondary spread from the already infected urinary organs. The epididymis are the commonest involved organs affected primarily by a hematogenous mode of spread. Tb is characterized by extensive destruction and fibrosis, thus an early diagnosis may prevent function and organ loss...

BACKGROUND: The detection and quantification of solid components in pulmonary subsolid nodules (SSN) are of vital importance on differential diagnosis, pathological speculation and prognosis prediction. However, no objective and wide-accepted criterion has been built up to now. The purpose of this study is to explore the optimal threshold that can be used for the detection and quantification of solid components in SSNs by using threshold segmentation method on computed tomography (CT) images...

BACKGROUND: Background and objective Follow up by computed tomography (CT) and growth evaluation are routine methods for the differential diagnosis of indeterminate pulmonary nodules in clinical practice. Pulmonary nodules with diverse biological behaviors may show different growth patterns and velocities. The aim of this study is to identify the volume growth curve of both benign and malignant pulmonary nodules. This work also intends to determine these nodules' growth patterns and provide evidence for the establishment of a follow-up strategy...

BACKGROUND: Navigational bronchoscopy and other imaging modalities have improved the ability to evaluate pulmonary nodules/mass. Many of these lesions are located outside the bronchial airway and are difficult to access even with these devices. The Transbronchial Access Tool (Medtronic, Minneapolis, MN) allows the bronchoscopist to create a pathway from the bronchial airway, across the lung parenchyma, and into the target lesion. We are reporting the feasibility and safety of this new device...

Mycobacterium chelonae is a nontuberculous mycobacterium, classified as a Runyon type IV mycobacterium. In relation to humans, it is most commonly associated with tissue trauma or pulmonary infections. The majority of medical reports describe finding M. chelonae in the surgical setting, attributing infection to inadequate sterilization of surgical equipment. Symptoms are often nonspecific and include pain, erythema, and draining subcutaneous nodules and skin lesions. Therefore, the diagnosis of M. chelonae is often difficult to establish without prior suspicion of the disease, but can be confirmed with culture...

A 36 year-old male with no significant past medical history presented with lower extremity numbness, gait instability, and urinary and bowel retention of 4 weeks onset. Spine MRI revealed diffuse oedema of cervicothoracic spinal cord with several solid enhancing intramedullary lesions, suggestive of metastases. The (18)F-FDG PET/CT performed to identify the primary malignancy demonstrated mild hypermetabolic foci within the cervicothoracic cord, as well as a mildly hypermetabolic bilateral hilar lymphadenopathy and a mildly hypermetabolic pulmonary nodule, suggestive of sarcoidosis versus metastasis...

We present the case of a patient with history of colon cancer, referred for the evaluation of indeterminate pulmonary nodules by F-FDG PET/CT. A dual-time point protocol was performed, and images were reconstructed using VUE Point HD and a Bayesian-penalized likelihood reconstruction algorithm (Q.Clear). Visually, the quality of the images was considered better when Q.Clear was used with β value of 200, uptake in the smallest nodule (7 mm) was clearly visible only with Q.Clear reconstruction, and uptake in the smaller nodules was best defined in the delayed time point acquisition...

Small and deeply seated pure ground-glass opacity (GGO) pulmonary nodules (PNs) are not discernible during video-assisted thoracoscopic surgery (VATS). Moreover, pathologists have difficulty in detecting these nodules due to insufficient localization. We percutaneously injected a mixture of lipiodol and India ink during preoperative CT-guided localization in a 52-year-old female patient presenting with a pure GGO PN. A black-pigmented tattoo lesion was clearly identified, and thoracoscopic wedge resection was performed without difficulty...

BACKGROUND: It is technically challenging to locate non-visible, non-palpable subcentimeter ground-glass nodules (GGNs) of lung during video-assisted thoracic surgery (VATS). Computed tomography (CT)-guided marking of small pulmonary nodules using microcoils has been reported to be a practical method of preoperative localization, whereas dislodgement of microcoils remains to be a bothersome complication. The objective of this study was to assess the viability and effectiveness of a newly developed hybrid technique, which combines induced controllable pneumothorax and CT-guided microcoil marking procedure to reduce the risk of microcoil dislodgement...

Thoracoscopic partial pulmonary resection for small peripheral nodules without using a stapler has been introduced to our hospital. After partial resection was performed with electrocautery, two different methods of surface sealing were used: a coagulation method (C method) with Soft Coagulation alone, and a coagulation-suturing method (CS method) with Soft Coagulation combined with continuous suturing. The clinical outcomes of the two methods were retrospectively compared in this study. The C method was used in 19 lesions of 18 cases, and the CS method was used in 20 lesions of 19 cases...

Thoracic endometriosis syndrome (TES) is a rare disorder presenting with catamenial pneumothorax, hemothorax, hemoptysis or pulmonary nodules. Bilateral involvement is uncommon, and only a very few cases have been reported in the literature. We report a case of bilateral catamenial hemothorax in a patient with recurrent thoracic endometriosis. Despite multiple surgical interventions, the patient continued to develop hemopneumothorax coinciding with menses. Remission was finally achieved with the addition of gonadotropin-releasing hormone agonist, highlighting the effectiveness of postoperative adjuvant hormone therapy and supporting a combined surgical and medical approach in the treatment of TES in patients who desire future fertility...

For inflammatory bowel disease (IBD), antitumor necrosis factor treatment offers a new direction for both patients and medical doctors. This treatment has dramatically improved the quality of life for patients with ulcerative colitis and Crohn disease (CD). However, with increasing usage and longer follow-up periods, a wider range of possible adverse effects may be encountered. We report an unusual case of pulmonary sarcoidosis developed during the treatment of a patient with CD by using infliximab. A 30-year-old male who had been treated for CD with infliximab for 18 months was admitted due to abnormal opacities on chest radiography...
