Pediatric Pneumonia is one of the principal causes of death by year on children under the age of five worldwide. The diagnosis is commonly made by clinical criteria with support from imaging tools like radiography. Lung ultrasound has been considered a low-cost and portable alternative for pneumonia imaging; however, interpretation is subjective and requires adequate training. In the present work, a pneumonia detection algorithm based on the measurement of the fundamental bandwidth downshift over depth of ultrasound radiofrequency (RF) signals is presented...

BACKGROUND: The ability of specific histopathological features to predict mortality or lung transplant in chronic hypersensitivity pneumonitis patients is unknown. METHODS: Patients with chronic hypersensitivity pneumonitis diagnosed by surgical lung biopsy were identified from an ongoing longitudinal cohort. The surgical lung biopsy slides were evaluated prospectively by an experienced thoracic pathologist using a standardized checklist to differentiate the major pathologic patterns and score the presence of specific histopathological features...

During a pneumonic plague outbreak in Moramanga, Madagascar, we identified 4 confirmed, 1 presumptive, and 9 suspected plague case-patients. Human-to-human transmission among close contacts was high (reproductive number 1.44) and the case fatality rate was 71%. Phylogenetic analysis showed that the Yersinia pestis isolates belonged to group q3, different from the previous outbreak.

Inhalation of Yersinia pestis can lead to pneumonic plague, which without treatment is inevitably fatal. Two novel formulations of liposome-encapsulated ciprofloxacin, 'ciprofloxacin for inhalation' (CFI, Lipoquin(®)) and 'dual release ciprofloxacin for inhalation' (DRCFI, Pulmaquin(®)) containing CFI and ciprofloxacin solution, are in development. These were evaluated as potential therapies for infection with Y. pestis. In a murine model of pneumonic plague, human-like doses of aerosolized CFI, aerosolized DRCFI or intraperitoneal (i...

Interstitial pneumonitis is a classical complication of many drugs. Pulmonary toxicity due to 5-azacytidine, a deoxyribonucleic acid methyltransferase inhibitor and cytotoxic drug, has rarely been reported. We report a 67-year-old female myelodysplastic syndrome patient treated with 5-azacytidine at the conventional dosage of 75 mg/m(2) for 7 days. One week after starting she developed moderate fever along with dry cough and subsequently her temperature rose to 39.5 °C. She was placed under broad-spectrum antibiotics based on the protocol for febrile neutropenia, including ciprofloxacin 750 mg twice daily, ceftazidime 1 g three times daily (tid), and sulfamethoxazole/trimethoprim 400 mg/80 mg tid...

Subglottic stenosis is a known complication of a traumatic and prolonged intubation. In a child, subglottic area is narrower and more prone to damage by an oversized or overinflated endotracheal tube. The stenosis can present with complaints of change in voice, croup, or respiratory obstruction. Those presenting with respiratory obstruction require immediate diagnosis under direct laryngoscopy and timely corrective intervention under general anesthesia. A 4-year-old child came to the emergency department with severe respiratory obstruction...

In 2013, a guideline for occupational allergic diseases was published for the first time in Japan. Occupational allergic diseases are likely to worsen or become intractable as a result of continuous exposure to high concentrations of causative antigens, and are socioeconomically important diseases with which the patients might sometimes lose jobs due to work interruptions. Guidelines for occupational allergic diseases have been published in many countries. This guideline consists of six chapters about occupational asthma, occupational allergic rhinitis, occupational skin diseases, hypersensitivity pneumonitis and occupational anaphylaxis shock, and legal aspects of these diseases...

Plasminogen activator inhibitor-1 (PAI-1) plays a crucial role in the process of lung injury, although its association with radiation pneumonitis (RP) is unclear. We hypothesized that genetic variants in PAI-1 may influence the risk of RP. In this study, 169 lung cancer patients were genotyped for six single-nucleotide polymorphisms in PAI-1 using the Sequenom MassARRAY system. The risk of RP was evaluated by Cox proportional hazards analyses. The cumulative RP probabilities by genotype were assessed using Kaplan-Meier analyses...

Pneumonitis and fibrosis are potentially lethal, delayed effects of acute radiation exposure. In this study, male rhesus macaques received whole-thorax lung irradiation (WTLI) with a target dose of 10.74 Gy prescribed to midplane at a dose rate of 0.80 ± 0.05 Gy/min using 6 MV linear accelerator-derived photons. The study design was comprised of four animal cohorts: one control and three treated with AEOL 10150 (n = 20 animals per cohort). AEOL 10150, a metalloporphyrin antioxidant, superoxide dismutase mimetic was administered by daily subcutaneous injection at 5 mg/kg in each of three schedules, beginning 24 ± 2 h postirradiation: from day 1 to day 28, day 1 to day 60 or a divided regimen from day 1 to day 28 plus day 60 to day 88...

BACKGROUND: Innate T helper type 2 (Th2) immune responses mediated by interleukin (IL)-33, thymic stromal lymphopoietin (TSLP), and IL-25 have been shown to play an important role in pulmonary fibrosis of animal models; however, their clinical implications remain poorly understood. METHODS: TSLP, IL-25, and IL-33 concentrations were measured in bronchoalveolar lavage fluids obtained from normal controls (NCs; n = 40) and from patients with idiopathic pulmonary fibrosis (IPF; n = 100), non-specific interstitial pneumonia (NSIP; n = 22), hypersensitivity pneumonitis (HP; n = 20), and sarcoidosis (n = 19)...

Tuberous sclerosis complex (TSC) is a genetic disorder characterised by highly variable comorbid dysfunction and subsequent morbidity. The mTOR inhibitor everolimus is indicated for the treatment of adult TSC patients with renal angiomyolipomas (AMLs) and for subependymal giant astrocytoma (SEGA) in both adults and children, based on data from the EXIST-1 and EXIST-2 trials. However, due to the historical predominance of everolimus in the oncology setting, some physicians who treat TSC patients may be unfamiliar with everolimus-associated adverse events (AEs) and appropriate management strategies...

We evaluated the use of vaginal implant transmitters (VITs) as a means of detecting, capturing, and radio collaring Rocky Mountain bighorn sheep ( Ovis canadensis canadensis) lambs to estimate survival and to facilitate carcass recovery to assess causes of mortality. We focused on one of several bighorn herds in Colorado, USA, suffering from depressed recruitment that was not preceded by a classic all-age die-off. We captured, radio-collared, diagnosed pregnancy by ultrasound examination, and inserted VITs into 15 pregnant ewes from a herd residing near Granite, Colorado...

Adult onset Still's disease is uncommon in middle-aged and elderly individuals and can rarely present with shock; shock is usually associated with disseminated intravascular coagulation, multiorgan dysfunction syndrome or acute respiratory distress syndrome. We report a post-menopausal woman with arthritis, fever, pneumonitis and hypotension which was managed as septic shock. Steroids were inadvertently missed during the second day of hospitalization in the intensive care unit. Persistence of hypotension on inotropes, with normal renal, hepatic and neurological function and recurrence of fever when steroids were skipped, led to suspicion of an inflammatory disorder...

BACKGROUND: MUC5B is glycoprotein secreted by bronchial glands. A promoter variant in MUC5B, rs35705950, was previously found to be strongly associated with the incidence of idiopathic pulmonary fibrosis (IPF) and also the overall survival (OS) of such patients. Patients with IPF and patients with radiation pneumonitis (RP) have the similar pathologic process and clinical symptoms. However, the role of rs35705950 in patients receiving thoracic radiotherapy remains unclear. PATIENTS AND METHODS: In total, 664 patients with NSCLC receiving definitive radiotherapy (total dose ≥60 Gy) were included in our study...

Bleomycin is an antineoplastic agent causing fatal pulmonary toxicity. Early diagnosis of bleomycin-induced pneumonitis is crucial to prevent irreversible damage. Pulmonary function tests are unreliable for identifying risk of bleomycin toxicity. Fluorodeoxyglucose PET/CT scanning can reveal inflammation secondary to pneumonitis but is not sufficiently specific for diagnosis. We retrospectively analyzed scans from 77 patients with Hodgkin lymphoma (median age 41 years, mean bleomycin dose 134 mg) to evaluate bleomycin-induced pneumonitis...
