Lung abscess is a localized area of non tuberculosis suppurative necrosis of the parenchyma lung, resulting in formation of a cavity containing purulent material. This pathology is uncommon in childhood. A 3-year-6 month-old boy was admitted with prolonged fever and dyspnea. Chest X-ray showed a non systemized, well limited, thick walled, hydric, and excavated opacity containing an air-fluid level. Chest ultrasound examination showed a collection of 6. 8 cm of diameter in the right pulmonary field with an air-fluid level. Hemoculture showed Staphylococcus aureus. The patient received large spectrum antibiotherapy. Three days after, he presented a septic shock and surgical drainage was indicated. Histological examination confirmed the diagnosis of lung abscess. Any underlying condition such as inoculation site, local cause or immune deficiency, was noted and diagnosis of primary abscess was made. The patient demonstrated complete recovery. He is asymptomatic with normal chest X-ray and pulmonary function after 3 years of evolution. Lung abscess represent a rare cause of prolonged fever in childhood. An underlying condition must be excluded to eliminate secondary abscess. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

A previously healthy, 30-year-old Filipino woman presented to an emergency department with complaints of shortness of breath and mild cough. She denied constitutional symptoms, such as night sweats, fevers, loss of appetite, or weight loss. Additional investigation revealed bilateral pleural and pericardial effusions with no obvious lung lesions or masses. The pericardial fluid was drained and preliminary cytology revealed atypical carcinoma cells. Her past medical history included an embryonic pregnancy and a benign breast cyst that was biopsied in the Philippines. She had immigrated to Canada two years earlier, was working full-time, and was living with her sister. She was planning on returning to the Philippines to wed and had a strong support system in Canada. She had never smoked cigarettes or consumed alcohol and had no family history of cancer. The patient was exposed to secondhand smoke as a child.

A 4-month-old boy with past medical history of eczema presented with fever and cough; a chest radiograph showed lung consolidation, and he was initially treated with amoxicillin for presumed community-acquired pneumonia. After several days, his fever persisted. He was also profoundly anemic. Antibiotic coverage was broadened because of the concern for resistant organisms; he began to improve and was discharged from the hospital. However, at 5 months of age, his fever returned, and he continued to demonstrate lung consolidation on chest radiograph. Additionally, he had lost weight and continued to be anemic. Splenic cysts were noted on abdominal ultrasound. He was diagnosed with an unusual etiology for his pneumonia and improved with the appropriate therapy. An underlying immunodeficiency was suspected, but initial testing was nondiagnostic. At 12 months of age, he presented with another infection, and the final diagnosis was made.

Background Epidermal growth factor receptor tyrosine kinase inhibitors significantly prolong the progression-free survival of patients with non-squamous non-small cell lung cancer (NSCLC). However, most patients develop tumor regrowth and their prognosis remains poor. A new treatment strategy for NSCLC harboring EGFR mutation is therefore necessary. Methods In phase I, eligible patients were administered oral erlotinib daily and intravenous pemetrexed, carboplatin, and bevacizumab every 3 weeks for four cycles with maintenance of pemetrexed and bevacizumab until progressive disease was observed. The dose of erlotinib was 100 mg for dose level 1 and 150 mg for dose level 2. The doses of pemetrexed, carboplatin, and bevacizumab were fixed at 500 mg/m2, area under the concentration–time curve of 6 mg/mL · min, and 15 mg/kg, respectively. The dose-limiting toxicities were grade 3/4 neutropenia with fever or infection, grade 4 leukopenia lasting for ≥7 days, grade 4 thrombocytopenia, grade 3/4 uncontrollable nonhematological toxicity, and delayed administration of the subsequent cycle by >2 weeks because of adverse events. Results Six patients were enrolled in phase I (dose level 1, n = 3; dose level 2, n = 3). During the induction phase, grade 3 neutropenia without fever was observed in one patient at dose level 1 and two patients at dose level 2. Grade 3 anemia was reported in one patient at dose level 1 and grade 3 thrombocytopenia was reported in two patients at dose level 1 and dose level 2, respectively. Conclusion Four-drug combination therapy is a feasible and promising. PMID:28740574

Crizotinib, which is effective in patients with anaplastic lymphoma kinase (ALK) positive non-small cell lung cancer, is sometimes associated with the generation of complex renal cysts. A 56-year-old man with ALK positive adenocarcinoma received crizotinib. Ten months after the introduction of crizotinib, a cystic lesion developed from his right kidney to the iliopsoas muscle, accompanied by fever, anemia, and hypoproteinemia. After 17 months of treatment, crizotinib was switched to alectinib, followed by the recovery of hypoproteinemia and systemic inflammation. Switching to alectinib may be beneficial in patients demonstrating crizotinib-associated complex renal cysts with systemic inflammation and exhaustion.

This index case alerts physicians toward a treatable infection which would not normally be susceptible to the empiric antibiotic regimens given neutropenic patients with fevers.

Bacterial lung sepsis in patients with febrile neutropenia.

2012-05-01

This review provides an update on microbiological and therapeutic data in febrile neutropenic patients in general and those with bacterial lung sepsis in particular. Although the Infectious Diseases Society of America updated its guidelines on febrile neutropenia in 2010, changing epidemiological factors and the spread of new drug resistance constitutes challenges for initial treatment of this condition. Lung sepsis stands out because of the frequent absence of microbiological identification. We review the use of newly available, novel, broad-spectrum antibiotics (linezolid, tigecycline, daptomycin, etc.) in this indication. Although the incidence of Gram-negative infections in neutropenic fever is leveling off, there is a worrying increase in resistance. New drugs are available but not well studied in febrile neutropenia; daptomycin and tigecycline should not be used in suspected lung sepsis in these patients. New diagnostic tools (such as the procalcitonin assay and the LightCycler SeptiFast assay, Roche Molecular Systems) appear to be unhelpful in febrile neutropenia, although more data on fungal sepsis are required. There are no specific features of the treatment of pneumonia or septic shock in neutropenic fever, but both conditions increase the mortality rate.

Houttuynia cordata Thunb. is a traditional herb used for clearing heat and eliminating toxins, and has also been used for the treatment of severe acute respiratory syndrome (SARS). In vitro, the crude H. cordata polysaccharides (CHCP) exhibited potent anti-complementary activity through both the classical and alternative pathways by acting on components C3 and C4 of the complement system without interfering with the coagulation system. This study was to investigate the preventive effects of CHCP on acute lung injury (ALI) induced by hemorrhagic shock plus lipopolysaccharide (LPS) instillation (two-hit) and LPS-induced fever in rats. CHCP significantly attenuated pulmonary injury in the "two-hit" ALI model by reducing pulmonary edema and protein exudation in bronchoalveolar lavage fluid (BALF). In addition, it reduced the deposit of complement activation products in the lung and improved oxidant-antioxidant imbalance. Moreover, CHCP administration inhibited fever in rats, reduced the number of leukocytes and restored serum complement levels. The inhibition on the inappropriate activation of complement system by CHCP may play an important role in its beneficial effects on inflammatory diseases. The anti-complementary polysaccharides are likely to be among the key substances for the heat-clearing function of H. cordata .

A 76-year-old woman came to us because of staggering, fever, dysarthria, and appetite loss. Magnetic resonance imaging (MRI) of the brain revealed multiple masses with surrounding edema. Chest X-ray and computed tomography demonstrated a mass-like lesion in the left lung and left pleural effusion. Lung cancer and multiple brain metastases were suspected. However, the brain lesions demonstrated a high intensity through diffusion-weighted MRI. The finding was an important key to differentiate brain abscesses from lung cancer metastases.

Extra skeletal Ewing Sarcoma (EES) is a rare entity which predominantly occurs in adolescents and young adults. It usually arises from the soft tissues of the trunk or the extremities. We present a case of EES arising from the left visceral pleura in a 21 year old female patient who presented to the emergency room of our institution with fever, productive cough and sternal pain radiating to the back for the last 3 days. Chest radiograph was firstly performed, followed by chest CT examination. Finally open lung biopsy revealed a small round cell malignancy. The mass was resected and the histological examination revealed Extra skeletal Ewing Sarcoma (EES) of the visceral pleura without involvement of the adjacent lung. Secondary multiple nodules at the lateral wall of the pleura were also noticed and so postoperative multiagent chemotherapy was performed. EES should be considered in the differential diagnosis of any patient, especially adolescents or young adults, with a soft tissue mass of the trunk or the extremities.

Purpose: A Phase I study to determine a recommended dose of thoracic radiotherapy using accelerated hyperfractionation for unresectable non-small-cell lung cancer was conducted. Methods and Materials: Patients with unresectable Stage III non-small-cell lung cancer were treated intravenously with carboplatin (area under the concentration curve 2) and paclitaxel (40 mg/m{sup 2}) on Days 1, 8, 15, and 22 with concurrent twice-daily thoracic radiotherapy (1.5 Gy per fraction) beginning on Day 1 followed by two cycles of consolidation chemotherapy using carboplatin (area under the concentration curve 5) and paclitaxel (200 mg/m{sup 2}). Total doses were 54 Gy in 36 fractions, 60 Gymore » in 40 fractions, 66 Gy in 44 fractions, and 72 Gy in 48 fractions at Levels 1 to 4. The dose-limiting toxicity, defined as Grade {>=}4 esophagitis and neutropenic fever and Grade {>=}3 other nonhematologic toxicities, was monitored for 90 days. Results: Of 26 patients enrolled, 22 patients were assessable for response and toxicity. When 4 patients entered Level 4, enrollment was closed to avoid severe late toxicities. Dose-limiting toxicities occurred in 3 patients. They were Grade 3 neuropathy at Level 1 and Level 3 and Grade 3 infection at Level 1. However, the maximum tolerated dose was not reached. The median survival time was 28.6 months for all patients. Conclusions: The maximum tolerated dose was not reached, although the dose of radiation was escalated to 72 Gy in 48 fractions. However, a dose of 66 Gy in 44 fractions was adopted for this study because late toxicity data were insufficient.« less

1998-01-01

The present state and the problems of G and GM-CSF in cancer chemotherapy, especially for solid tumors in Japan, were reviewed. One of the problems is that adaptation is restricted to several tumors, and the other that recommended doses are about half or one-fourth as much as in North America or Europe. With G-CSF after dose-intensive chemotherapy in small-cell lung cancer, three studies showed G-CSF shortened the duration of neutropenia, and reduced the incidence of neutropenic fever, use of antibiotics and hospitalization, while they showed no advantages in terms of response rate and the incidence of infection-related death. Moreover, the effect on survival has not been proved. In afebrile neutropenic patients, G-CSF could accelerate recovery from neutropenia, but did not reduce the incidence of neutropenic fever. In febrile neutropenic patients with antibiotics, it could also accelerate recovery from neutropenia, but did not reduce neutropenic fever compared with no CSF except in some subsets. Our retrospective study showed the effects of G-CSF in grade 4 neutropenia were comparable with grade 3 neutropenia. The functions of neutrophils with G-CSF after chemotherapy were reported to be increased or maintained. Clinical benefits were only obtained in certain dose-intensive chemotherapy or in limited subsets. Additional clinical trials and a guideline like ASCO's should be planned.

Fever of unknown origin (FUO) remains one of the most difficult diagnostic challenges. The causes of FUO can be various diseases located in different organs. The aim of the study was to determine the prevalence and nature of pulmonary lesions during FUO. One hundred and sixty one patients with FUO participated in this prospective study. We performed a detailed comprehensive history, physical examination, and a wide spectrum of tests. The most common causes of FUO were infections (39%), autoimmune conditions (28%), and neoplasms (17%). Lung lesions were found in 30% of patients. In this group 35% were infections, 30% autoimmune diseases, and 4% cancer. Among patients with respiratory infections, there were cases of tuberculosis, atypical pneumonia, lung abscess, and bronchiectases. Autoimmune pulmonary lesions were observed during vasculitis and systemic lupus. The causes of FUO in the group of patients with lung lesions were also pulmonary embolism, sarcoidosis, and pulmonary fibrosis. Chest CT played an important role in the diagnosis of the causes of FUO with pulmonary manifestations. Pulmonary lesions are a common cause of FUO. Most FUO with pulmonary lesions are recognized during infections and autoimmune diseases. An important part of diagnosing FUO is a detailed evaluation of the respiratory system.

Lung abscess has been considered to be a rare complication of pneumococcal infection, and most cases are reported to be Streptococcus pneumoniae serotype 3. A 67-year-old man presented with fever and was diagnosed to have lung abscess caused by S. pneumoniae serotype 6B. The minimal inhibitory concentration (MIC) of penicillin for the isolate was 1 μg/mL. He was treated with high-dose intravenous sulbactam/ampicillin as definitive therapy based on susceptibility testing for S. pneumoniae and recovered successfully without surgical intervention. S. pneumoniae serotype 6B can cause lung abscess.

While visiting Malaysia, a 22-year-old previously healthy Japanese man developed myalgia, headache, and fever, leading to a diagnosis of classical dengue fever. After improvement and returning to Japan after a five day hospitalization, he developed productive cough several days after defervescing from dengue. Computed tomography (CT) thorax scan showed multiple lung cavities. A sputum smear revealed leukocytes with phagocytized gram-positive cocci in clusters, and grew an isolate Staphylococcus aureus sensitive to semi-synthetic penicillin; he was treated successfully with ceftriaxone and cephalexin. This second reported case of pneumonia due to S. aureus occurring after dengue fever, was associated both with nosocomial exposure and might have been associated with dengue-associated immunosuppression. Clinicians should pay systematic attention to bacterial pneumonia following dengue fever to establish whether such a connection is causally associated. © The American Society of Tropical Medicine and Hygiene.

To explore the clinical characteristics and prognostic factors of pulmonary tuberculosis with concurrent lung cancer. Comprehensive analyses were conducted for 58 cases of pulmonary tuberculosis patients with lung cancer. Their clinical symptoms, signs and imaging results were analyzed between January 1998 and January 2005 at Qingdao Chest Hospital. Kaplan-Meier method was utilized to calculate their survival rates. Nine prognostic characteristics were analyzed. Single factor analysis was performed with Logrank test and multi-factor analysis with Cox regression model. The initial symptoms were cough, chest tightness, fever and hemoptysis. Chest radiology showed the coexistence of two diseases was 36 in the same lobe and 22 in different lobes. And there were pulmonary nodules (n = 24), cavities (n = 19), infiltration (n = 8) and atelectasis (n = 7). According to the pathological characteristics, there were squamous carcinoma (n = 33), adenocarcinoma (n = 17), small cell carcinoma (n = 4) and unidentified (n = 4) respectively. The TNM stages were I (n = 13), II(n = 22), III (n = 16) and IV (n = 7) respectively. The median survival period was 24 months. And the 1, 3, 5-year survival rates were 65.5%, 65.5% and 29.0% respectively. Single factor analysis showed that lung cancer TNM staging (P = 0.000) and tuberculosis activity (P = 0.024) were significantly associated with patient prognosis. And multi-factor analysis showed that lung cancer TNM staging (RR = 2.629, 95%CI: 1.759-3.928, P = 0.000) and tuberculosis activity (RR = 1.885, 95%CI: 1.023-3.471, P = 0.042) were relatively independent prognostic factors. The clinical and radiological characteristics contribute jointly to early diagnosis and therapy of tuberculosis with concurrent lung cancer. And TNM staging of lung cancer and activity of tuberculosis are major prognostic factors.

The purpose of this paper was to investigate the clinical and radiological features of pulmonary tuberculosis presenting as interstitial lung diseases (ILD). We analyzed the data of cases suspected of diffuse parenchyma lung diseases at this hospital between October 2003 and October 2007. The diagnosis of active pulmonary tuberculosis was based on epithelioid granuloma or positive acid-fast bacilli in lung biopsy and changes on serial radiographs obtained during treatment. The data of a series of 230 consecutive patients with suspected ILD were retrospectively analyzed. The diagnosis was confirmed by lung biopsy. Twelve patients were confirmed to have pulmonary tuberculosis. There were 5 males and 7 females with a mean age of 38 +/- 11 years (range, 17 - 68). The median course of disease in these patients was 3 months (range, 0.5 - 18 months). Patients with pulmonary tuberculosis presented with fever (11/12), cough (9/12), weight loss (7/12), dyspnea (7/12), lymphadenopathy (4/12), and splenohepatomegaly (2/12). On chest CT scan, ground-glass attenuation was identified in 4, bilateral patchy infiltration in 5, tree-in-bud appearance 1, and centrilobular lesions in 2 of the 12 patients. During the follow-up period (median, 9 month, range from 3 to 12 month), 11 patients improved, but 1 died of diabetic ketoacidosis. The diagnosis of pulmonary tuberculosis should be considered in suspected ILD patients presenting with fever, splenohepatomegaly and lymphadenopathy.

Stripping of chest tubes to promote drainage of the thorax of postthoracotomy patients has been routine practice, based on tradition. Recent published findings indicate that significant negative pressures are generated in the tube during stripping that could cause pain, bleeding and possible damage to the patient's lung tissue. To determine whether pediatric oncology patients whose chest tubes were not stripped would differ in frequency of pain, fever or lung complications from patients who underwent routine tube stripping. Data were collected at multiple points during the first 72-hour postoperative period from 16 patients assigned to the stripped or unstripped groups. Pain was measured by the Faces Pain Scale and the Visual Analogue Scale; temperature, by electronic thermometer; and lung complications, by stethoscope and radiographs. Both groups, which were comparable for age, primary diagnosis and prior history of lung problems, received identical supportive nursing and medical care, with the physicians blind to group assignment. The two groups did not differ significantly in frequency of pain, incidence of fever, breath sounds or radiographic findings across measurement points. A strong correlation was found between the pain scores using the two instruments. Patients whose tubes were not stripped did not have an increased risk of infection or lung complications. Study findings indicated that stripping did not increase the frequency of pain. Stripping of chest tubes as a routine postoperative measure is questioned.

Recently an increasing number of patients presented with febrile and respiratory symptoms associated with exposure to a new type of domestic ultrasonic humidifier. We report on 14 patients (5 females, 9 males; average age 42.5 17.4 years) with recurrent episodes of fever, cough and dyspnea after repeated exposure to ultrasonic misting fountain at home. A diagnosis of extrinsic allergic alveolitis (humidifier lung: 12 patients) or toxic alveolitis (humidifier fever: 2 patients) was made on the basis of the history and the clinical, radiological, laboratory and immunological findings. 10 patients had a partial respiratory insufficiency at rest or on exercise, 9 had a restrictive ventilatory abnormality. The chest x-ray was abnormal in 7 patients. Of 8 patients in whom computed tomography was done 6 had typical changes of an exogenous allergic alveolitis. Bronchoalveolar lavage revealed lymphocytic alveolitis in 8 patients. In 12 patients bacteria, moulds and/or yeasts were demonstrated in the humidifier fluid which they had used. 13 patients had IgG antibodies to the humidifier fluid. 8 patients were subjected to inhalative challenge tests to their own ultrasonic misting fountain: all of them had positive reactions. These cases demonstrate the potential of ultrasonic humidifying devices to cause illness in the home. In view of their increasing popularity, humidifier lung and humidifier fever should be considered in the differential diagnosis of patients with unexplained pulmonary or flu-like illness with fever.

A 38-year-old woman was admitted to our hospital because of recurrent chest pain and fever. Chest X-ray films and computed tomograms showed subpleural consolidation containing small cavity-like opacities. Open lung biopsy revealed non-infectious abscess and vessels with organizing thrombus. The patient was given a diagnosis of pulmonary infarction due to the existence of deep venous thrombosis. Coagulation studies demonstrated that she had decreased plasma protein S activity, whereas her free and total protein S antigen levels were normal. Because her mother and maternal uncle and aunt also demonstrated decreased protein S activity with normal plasma protein S antigen levels, the patient was considered to be affected by familial protein S deficiency type III.

Kaira, Kyoichi; Sunaga, Noriaki; Yanagitani, Noriko

Purpose: To determine the maximum tolerated dose (MTD) and recommended dose (RD) of S-1 in combination with cisplatin and thoracic radiotherapy in patients with unresectable Stage III non-small-cell lung cancer (NSCLC). Methods and Materials: S-1 was administered orally twice daily for 14 days and cisplatin on Days 1 and 8 of each cycle; this was repeated every 3 weeks. Doses of each drug were planned as follows: level 0, 50/40; level 1, 60/40; level 2, 70/40; level 3, 80/40 (S-1 [mg/m{sup -2}/day{sup -1}]/cisplatin [mg/m{sup -2}/day{sup -1}]). Thoracic radiation therapy was administered in 2 Gy fractions five times weekly to amore » total dose of 60 Gy. Results: Ten patients were enrolled in this study. All patients received 60 Gy of thoracic radiotherapy and 7 (70%) patients received four cycles of chemotherapy. At level 1, 2 of 3 patients experienced a delay exceeding 10 days in the cisplatin administration of Day 29. Grade 4 neutropenia and Grade 3 fever occurred in 1 and 1 patients, respectively. Nonhematologic toxicities were mild. None developed {>=}Grade 3 esophagitis or lung toxicity. At level 0, 2 of 7 patients developed dose-limiting toxicity. Thus, level 1 was considered the MTD and Level 0 was selected as the RD. Objective responses were seen in all patients. Conclusions: The RD is the level 0 dose, and this regimen is a feasible and well-tolerated regimen for the treatment of patients with Stage III NSCLC.« less

We described three cases of eosinophilic pneumonia of unknown aetiology investigated clinically and by lung biopsy. The illnesses lasted between six and 20 weeks and consisted of cough, dyspnoea, malaise, and in two cases prolonged pyrexia. All had blood eosinophilia and chest radiographs showing widespread bilateral shadowing; in two cases this had a characteristic peripheral distribution. One patient recovered spontaneously and the other two responded to steroids, with disappearance of pyrexia within 12 hours and radiological clearing within 14 days. Lung function tests during the acute illness showed volume restriction or gas transfer defects or both in two cases. After remission all three showed abnormalities if small airways function. Lung biopsies performed during the acute illness were examined histologically and by transmission electron microscopy, and in two cases by immunofluorescence. There was both intra-alveolar and interstitial eosinophilic pneumonia with bronchiolitis obliterans, microgranulomata, and a vasculitis. Electron microscopy showed numerous eosinophils, many degranulated, and macrophages with phagocytosed eosinophilic granules and intracytoplasmic inclusions. In one case IgM, IgG, and IgA were demonstrated in the bronchial walls and interstitium. No IgE or complement was present. We believe that eosinophil granules are responsible for the tissue damage and fever and suggest mechanisms for this and for the response to steroid therapy. Images PMID:7003796

Machupo virus, the cause of Bolivian hemorrhagic fever, is a highly lethal viral hemorrhagic fever with no Food and Drug Administration-approved vaccines or therapeutics. This study evaluated the guinea pig as a model using the Machupo virus-Chicava strain administered via aerosol challenge. Guinea pigs (Cavia porcellus) were serially sampled to evaluate the temporal progression of infection, gross and histologic lesions, and sequential changes in serum chemistry and hematology. The incubation period was 5 to 12 days, and complete blood counts revealed leukopenia with lymphopenia and thrombocytopenia. Gross pathologic findings included congestion and hemorrhage of the gastrointestinal mucosa and serosa, noncollapsing lungs with fluid exudation, enlarged lymph nodes, and progressive pallor and friability of the liver. Histologic lesions consisted of foci of degeneration and cell death in the haired skin, liver, pancreas, adrenal glands, lymph nodes, tongue, esophagus, salivary glands, renal pelvis, small intestine, and large intestine. Lymphohistiocytic interstitial pneumonia was also present. Inflammation within the central nervous system, interpreted as nonsuppurative encephalitis, was histologically apparent approximately 16 days postexposure and was generally progressive. Macrophages in the tracheobronchial lymph node, on day 5 postexposure, were the first cells to demonstrate visible viral antigen. Viral antigen was detected throughout the lymphoid system by day 9 postexposure, followed by prominent spread within epithelial tissues and then brain. This study provides insight into the course of Machupo virus infection and supports the utility of guinea pigs as an additional animal model for vaccine and therapeutic development. © The Author(s) 2015.

The objective of the present longitudinal study was to investigate the effects of occupational endotoxin exposure on respiratory health and atopic sensitization in adults. Health outcomes and personal endotoxin exposure estimates were determined for 234 farmers and agricultural workers both at baseline and 5 years later. A questionnaire was used to assess respiratory symptoms, spirometry tests were performed and total and specific IgE levels were measured in serum. A twofold increase in personal endotoxin exposure was associated with less hay fever (OR 0.68, 95%CI 0.54-0.87) and grass IgE positivity (OR 0.81, 95%CI 0.68-0.97) at both time points ("persistent" versus "never"). Although not statistically significant, a consistent protective pattern was observed for an increased loss of hay fever symptoms (OR 2.19, 95%CI 0.96-4.99) and grass IgE positivity (OR 1.24, 95%CI 0.76-2.02), and for less new-onset of hay fever (OR 0.87, 95%CI 0.65-1.17), grass IgE positivity (OR 0.83, 95%CI 0.61-1.12) and atopic sensitization (OR 0.75, 95%CI 0.55-1.02). Endotoxin exposure was not associated with changes in lung function. We showed that occupational endotoxin exposure is associated with a long-term protective effect on hay fever and grass IgE positivity. Results on longitudinal changes in hay fever, atopy and grass IgE positivity in adulthood were consistent with a protective effect of endotoxin exposure, but results need to be confirmed in larger cohorts. An effect of endotoxin exposure on lung function decline was not found.

Far-eastern spotted fever is an emerging disease caused by Rickettsia heilongjiangensis, a tick-borne obligate intracellular bacterium. In this study, R. heilongjiangensis was used to infect BALB/c mice by inoculation of retro-orbital venous plexus to imitate a blood infection caused by tick biting. We found that R. heilongjiangensis rapidly entered the circulation for systemic dissemination and the pathogen existed in liver, spleen, lungs, and brain of the mice at least 9 days post-infection (p.i.). Severe pathological lesions were observed in liver, lungs, and brain at Day 6 p.i. In addition, the elevated levels of inflammatory cytokines, including interferon-γ, tumor necrosis factor, and CC chemokine, were detected in the infected organs at Day 3 p.i. Our results reveal that R. heilongjiangensis may cause an infection in BALB/c mice and the pathological lesions in the infected mice are associated with host inflammatory response induced by R. heilongjiangensis.

Pneumocystis pneumonia presented in a homosexual with fever, a normal chest radiograph, and pulmonary gallium uptake. Bronchial washings yielded Mycobaterium tuberculosis, but despite antituberculosis therapy he remained febrile, and gallium uptake in the lung increased. Subsequently, silver stain of transbronchial lung biopsy obtained 2 months earlier at the time that tuberculosis was diagnosed showed many Pneumocystis cysts in alveolar spaces. In contrast to Pneumocystis cysts in infected lung tissue from other humans, our patient's Pneumocystis cysts reacted more avidly with antiserum to rat Pneumocystis than with antiserum to human pneumocystis, raising the possibility that organisms that infect humans may havemore » varied surface antigenic properties.« less

Granulomatosis with polyangiitis (GPA, previously known as Wegener's granulomatosis) is an autoimmune systemic small-vessel vasculitis, associated with the presence of anti-neurophil cytoplasmic antibodies with a cytoplasmic staining pattern (c-ANCA). It is characterized by necrotizing granulomas, usually affecting the airways and kidneys. GPA should be considered when patients do not improve despite adequate treatment of otologic symptoms, when patients have unspecific symptoms suggesting systemic disease (e.g. fever, malaise), or when other organs are involved (kidney, lungs, etc.). We present an interesting case of a 14-year-old female with eight-weeks of bilateral otalgia, unilateral facial nerve palsy, decreased appetite, and fatigue refractory to steroid, anti-viral, and antibiotic treatment ultimately diagnosed with GPA.

Lujo virus (LUJV) is a novel member of the Arenaviridae family that was first identified in 2008 after an outbreak of severe hemorrhagic fever (HF). In what was a small but rapidly progressing outbreak, this previously unknown virus was transmitted from the critically ill index patient to 4 attending healthcare workers. Four persons died during this outbreak, for a total case fatality of 80% (4/5). The suspected rodent source of the initial exposure to LUJV remains a mystery. Because of the ease of transmission, high case fatality, and novel nature of LUJV, we sought to establish an animal model of LUJV HF. Initial attempts in mice failed, but infection of inbred strain 13/N guinea pigs resulted in lethal disease. A total of 41 adult strain 13/N guinea pigs were infected with either wild-type LUJV or a full-length recombinant LUJV. Results demonstrated that strain 13/N guinea pigs provide an excellent model of severe and lethal LUJV HF that closely resembles what is known of the human disease. All infected animals experienced consistent weight loss (3–5% per day) and clinical illness characterized by ocular discharge, ruffled fur, hunched posture, and lethargy. Uniform lethality occurred by 11–16 days post-infection. All animals developed disseminated LUJV infection in various organs (liver, spleen, lung, and kidney), and leukopenia, lymphopenia, thrombocytopenia, coagulopathy, and elevated transaminase levels. Serial euthanasia studies revealed a temporal pattern of virus dissemination and increasing severity of disease, primarily targeting the liver, spleen, lungs, and lower gastrointestinal tract. Establishing an animal LUJV model is an important first step towards understanding the high pathogenicity of LUJV and developing vaccines and antiviral therapeutic drugs for this highly transmissible and lethal emerging pathogen.

To investigate the clinical and sociomedical outcome in patients with various clinical manifestations of humidifier disease and work related asthma after removal from further exposure. Follow up investigation (range 1-13 years) of respiratory symptoms, spirometry, airway responsiveness, sickness absence, and working situation in patients with (I) humidifier fever (n = 12), (II) obstructive type of humidifier lung (n = 8), (III) restrictive type of humidifier lung (n = 4), and (IV) work related asthma (n = 22). All patients were working at departments in synthetic fibre plants with microbiological exposure from contaminated humidification systems or exposure to small particles (< 1 micron) of oil mist. At follow up patients with work related asthma were less often symptom free (37%, 7/19) than patients with humidifier disease (I, II, III) (67%, 16/24). Mean forced expiratory volume in one second (FEV1) of patients with obstructive impairment had been increased significantly at follow up but still remained below the predicted value. Mean forced vital capacity (FVC) of patients with initially restrictive impairment had returned to normal values at follow up. Airway hyperresponsiveness at diagnosis persisted in patients with obstructive impairment (II + IV 14/17, but disappeared in patients with humidifier fever (3/3) and restrictive type of humidifier lung (2/2). In patients with obstructive impairment (II + IV), FVC and FEV1 at diagnosis were negatively associated with the duration between onset of symptoms and diagnosis and the number of years of exposure. Those with positive pre-employment history of respiratory disease had a lower FEV1 at diagnosis. Sickness absence due to respiratory symptoms decreased in all groups of patients after removal from further exposure, but this was most impressive in patients with the humidifier lung (II, III) and patients with work related asthma (IV). At follow up 83% of the patients were still at work at the same production site, whereas 11% received a disability pension because of respiratory disease. In patients with work related respiratory disease caused by exposure from contaminated humidification systems or oil mist, removal from further exposure resulted in clinical improvement, although, especially in those with obstructive impairment, signs persisted. Because of the possibility of transferring patients to exposure-free departments most patients could be kept at work.

Bacterial infection profiles in lung cancer patients with febrile neutropenia

PubMed Central

2011-01-01

Background The chemotherapy used to treat lung cancer causes febrile neutropenia in 10 to 40% of patients. Although most episodes are of undetermined origin, an infectious etiology can be suspected in 30% of cases. In view of the scarcity of data on lung cancer patients with febrile neutropenia, we performed a retrospective study of the microbiological characteristics of cases recorded in three medical centers in the Picardy region of northern France. Methods We analyzed the medical records of lung cancer patients with neutropenia (neutrophil count < 500/mm3) and fever (temperature > 38.3°C). Results The study included 87 lung cancer patients with febrile neutropenia (mean age: 64.2). Two thirds of the patients had metastases and half had poor performance status. Thirty-three of the 87 cases were microbiologically documented. Gram-negative bacteria (mainly enterobacteriaceae from the urinary and digestive tracts) were identified in 59% of these cases. Staphylococcus species (mainly S. aureus) accounted for a high proportion of the identified Gram-positive bacteria. Bacteremia accounted for 60% of the microbiologically documented cases of fever. 23% of the blood cultures were positive. 14% of the infections were probably hospital-acquired and 14% were caused by multidrug-resistant strains. The overall mortality rate at day 30 was 33% and the infection-related mortality rate was 16.1%. Treatment with antibiotics was successful in 82.8% of cases. In a multivariate analysis, predictive factors for treatment failure were age >60 and thrombocytopenia < 20000/mm3. Conclusion Gram-negative species were the most frequently identified bacteria in lung cancer patients with febrile neutropenia. Despite the success of antibiotic treatment and a low-risk neutropenic patient group, mortality is high in this particular population. PMID:21707992

To compare the survival benefit obtained with cisplatin plus gemcitabine, a cisplatin-based triplet, and nonplatinum sequential doublets in advanced non-small-cell lung cancer (NSCLC). Stage IIIB to IV NSCLC patients were randomly assigned to receive cisplatin 100 mg/m2 day 1 plus gemcitabine 1,250 mg/m2 days 1 and 8, every 3 weeks for six cycles (CG); cisplatin 100 mg/m2 day 1 plus gemcitabine 1,000 mg/m2 and vinorelbine 25 mg/m2 days 1 and 8, every 3 weeks for six cycles (CGV); or gemcitabine 1,000 mg/m2 plus vinorelbine 30 mg/m2 days 1 and 8, every 3 weeks for three cycles, followed by vinorelbine 30 mg/m2 days 1 and 8 plus ifosfamide 3 g/m2 day 1, every 3 weeks for three cycles (GV-VI). Five hundred fifty-seven patients were assigned to treatment (182 CG, 188 CGV, 187 GV-VI). Response rates were significantly inferior for the nonplatinum sequential doublet (CG, 42%; CGV, 41%; GV-VI, 27%; CG v GV-VI, P =.003). No differences in median survival or time to progression were observed. Toxicity was higher for the triplet: grade 3 to 4 neutropenia (GC, 32%; CGV, 57%; GV-VI, 27%; P <.05); neutropenic fever (CG, 4%; CGV, 19%; GV-VI, 5%; P <.0001); grade 3 to 4 thrombocytopenia (CG, 19%; CGV, 23%; GV-VI, 3%; P =.0001); and grade 3 to 4 emesis (GC, 22%; GCV, 32%; GV-VI, 6%; P <.0001). On the basis of these results, CG remains a standard regimen for first-line treatment of advanced NSCLC.

This study was undertaken to analyze the characteristics of fever after cancer chemotherapy in order to reduce unnecessary medical care. Retrospectively, 1016 consecutive cycles of cancer chemotherapy were analyzed. Fever was defined as a temperature of ≥ 37.5 °C lasting for 1 h. Age, sex, tumor histology, the treatment regimen, the timing of fever onset, the number of days for which the fever persisted, the cause of the fever, the presence or absence of radiotherapy, and the use of granulocyte colony-stimulating factor (G-CSF) were examined. The patients included 748 males and 268 females (median age = 68, range = 29-88), of whom 949, 52, and 15 were suffering from lung cancer, malignant pleural mesothelioma, and other diseases, respectively. Fever was observed in 367 cycles (36 %), including 280 cycles (37 %) involving males and 87 cycles (32 %) involving females. Fever occurred most commonly in the first cycles and was higher than later cycles (41 vs. 30 %, p < 0.001). Fever occurred most frequently on posttreatment days 4 (8 %), 3 (7 %), and 12 (7 %), and the distribution of fever episodes exhibited two peaks on posttreatment days 3 and 4 and 10-14. Fever on posttreatment days 3 and 4 was most commonly observed in patients treated with gemcitabine (20 %) or docetaxel (18 %). The causes of fever included infection (47 %; including febrile neutropenia [24 %]), adverse drug effects (24 %), unknown causes (19 %), and tumors (7 %). Radiotherapy led to a significant increase in the frequency of fever (46 vs. 34 %, p < 0.001). Thirty-three percent of patients received G-CSF, and the incidence ratios of fever in patients who received G-CSF were higher than those who did not receive G-CSF (44 vs. 31 %, p < 0.001). The febrile episodes that occurred on posttreatment days 3 and 4 were considered to represent adverse drug reactions after cancer chemotherapy. Physicians should be aware of this feature of chemotherapy-associated fever and avoid unnecessary examination and treatments including prescribing antibiotics.

Sarcoidosis with fever and a splenic infarct due to CMV or lymphoma?

PubMed

Cunha, Burke A; Sivarajah, Thulashie; Jimada, Ismail

We present a case of an adult female with a past history of pulmonary sarcoidosis who presented with fever, night sweats, profound fatigue, and LUQ abdominal pain. Sarcoidosis is an afebrile disorder (excluding Lofgren's syndrome, Heerfordt's syndrome or neurosarcoidosis). Therefore, the presence of fever with sarcoidosis should suggest infection, usually viral, or lymphoma. Sarcoidosis-lymphoma syndrome describes the evolution of a lymphoma in long standing sarcoidosis. Fever aside, possible lymphoma is suggested by otherwise unexplained fever, pleural unilateral effusion, highly elevated ESR or ferritin levels. In this case, a viral etiology was suggested because of atypical lymphocytosis and mildly elevated transaminases. In this patient, CMV IgM titers and elevated CMV PCR viral load confirmed the diagnosis of CMV infectious mononucleosis with lung and liver involvement. In this case CMV infectious mononucleosis was accompanied by procoagulant activity which resulted a DVT, pulmonary emboli and splenic infarct. We believe this to be the first reported case of CMV infectious mononucleosis splenic infarct in a patient with a history of sarcoidosis. Copyright © 2017 Elsevier Inc. All rights reserved.

We present a case of a lung abscess in a child 6-year-old admitted with a history of right hemithorax pain lasting for 15 days and the onset of mild fever in the last two days. Etiological research showed positivity of IgM antibodies to Mycoplasma pneumoniae after seven days of admission. The child has been successfully treated with antibiotic therapy, without the use of macrolides, for a duration of 4 weeks. Our study suggests that the Mycoplasma pneumoniae infection may predispose to severe infections, such as lung abscess, caused by typical respiratory pathogens. The reported case of lung abscess is one of the few reported in the literature in the modern antibiotic era and is the first preceded by Mycoplasma pneumoniae infection.

32-year-old man was seen in a clinic because of prolonged cough and slight-fever. Chest X-ray showed multiple pulmonary nodules, and multiple lung and mediastinal lymph node metastases from right testicular tumor was suspected by positron emission tomography/CT (PET/CT) scan. He was diagnosed with right testicular germ cell tumor (embryonal carcinoma + seminoma, pT2N1M1b), and classified into the intermediate risk group according to International Germ Cell Cancer Collaborative Group. He underwent 4 cycles of chemotherapy with bleomycin, etoposide and cisplatin (BEP therapy). During BEP therapy, sputum with foul odor appeared and chest CT scan revealed lung abscess with a necrotic lesion of metastatic tumor. The lung abscess was treated successfully with antibiotics.

Development of acute pulmonary hypertension after bortezomib treatment in a patient with multiple myeloma: a case report and the review of the literature.

Bortezomib is widely used in treatment of multiple myeloma. In recent years, severe bortezomib-induced lung injury has been reported. The clinical course is generally characterized with fever and dyspnea, followed by respiratory failure with pulmonary infiltrates. Herein, we report a 57-year-old man with newly diagnosed multiple myeloma admitted with dyspnea, fever, and hypotension on the third day of the first dose of bortezomib therapy. He had bilateral jugular venous distention, crackles at the bases of the lungs and hepatomegaly. Transthoracic echocardiography revealed acute pulmonary hypertension (PH) with an estimated pressure of 70 mm Hg. The perfusion scintigraphy ruled out pulmonary embolism, and microbiological examination was negative. On his course, fever, dyspnea, hypoxia, and pulmonary vascular pressure subsided rapidly. The sudden onset of PH and its rapid decrement without any treatment suggests bortezomib as the underlying cause. Subsequently, the patient did not respond to vincristine-doxorubicin-dexamethasone regimen and thalidomide. Bortezomib treatment was repeated, and no pulmonary adverse reactions occurred. Follow-up echocardiographies revealed pulmonary arterial pressures to be maximally of 35 mm Hg. To our knowledge, this is the first case of acute PH after front-line bortezomib therapy. In this report, we review bortezomib-related pulmonary complications in the literature and possible underlying mechanisms.

A 51-year-old man was diagnosed with colon cancer in September 2011, and a solitary pulmonary nodule was detected by computed tomography (CT) scan. We performed a transbronchial biopsy with endobronchial ultrasonography using a guide sheath (GS) and diagnosed lung metastasis of colon cancer. The patient experienced remittent fever after the biopsy in spite of intravenous antibiotic therapies. Moreover, his CT scan showed a large lung abscess at the biopsy site. We performed transbronchial drainage using a GS as salvage therapy. The bloody pus was successfully aspirated, and chest X-ray following the procedure showed dramatic shrinkage of the abscess.

Objective Whether areas affected by Q fever during a large outbreak (2008–2010) had higher rates of adverse pregnancy outcomes than areas not affected by Q fever. Design Nationwide registry-based ecological study. Setting Pregnant women in areas affected and not affected by Q fever in the Netherlands, 2003–2004 and 2008–2010. Participants Index group (N=58 737): pregnant women in 307 areas with more than two Q fever notifications. Reference group (N=310 635): pregnant women in 921 areas without Q fever notifications. As a baseline, pregnant women in index and reference areas in the years 2003–2004 were also included in the reference group to estimate the effect of Q fever in 2008–2010, and not the already existing differences before the outbreak. Main outcome measures Preterm delivery, small for gestational age, perinatal mortality. Results In 2008–2010, there was no association between residing in a Q fever-affected area and both preterm delivery (adjusted OR 1.01 (95% CI 0.94 to 1.08)), and perinatal mortality (adjusted OR 0.87 (95% CI 0.72 to 1.05)). In contrast, we found a weak significant association between residing in a Q fever-affected area in 2008–2010 and small for gestational age (adjusted OR 1.06 (95% CI 1.01 to 1.12)), with a population-attributable fraction of 0.70% (95% CI 0.07% to 1.34%). We observed no dose–response relation for this outcome with increasing Q fever notifications, and we did not find a stronger association for women who were in their first trimester of pregnancy during the months of high human Q fever incidence. Conclusions This study found a weak association between residing in a Q fever-affected area and the pregnancy outcome small for gestational age. Early detection of infection would require mass screening of pregnant women; this does not seem to be justified considering these results, and the uncertainties about its efficacy and the adverse effects of antibiotic treatment.

Q fever at the turn of the century.

PubMed

Chmielewski, Tomasz; Tylewska-Wierzbanowska, Stanisława

2012-01-01

Q fever is an infectious zoonotic disease characterized by sudden fever, headache, and atypical pneumonia, caused by Coxiella burneti--an obligatory intracellular parasite. Based on phylogenetic analysis of the genes sequences, the classification was changed and C. burnetii species was included to the gamma subgroup of the proteobacteria, Legionellales order and Coxiellaceae family. This analysis showed more than 99% sequence similarity of 16SrRNA gene among the strains isolated in different regions of the world. Q fever is a widespread in the world zoonosis. Its main reservoir in the rural environment are farm animals: cows, sheep, goats, and urban pets such as dogs, cats, rabbits. In acute infection these bacteria are detected in various internal organs such as lungs, liver, spleen, and in excretion in urine, faeces and milk. During childbirth, they occur in large number in the amniotic fluid and placenta. Recently, it has been found that free-living amoeba Acanthamoeba castellani may also be a reservoir of the pathogen. The intra-amoebal location of C. burnetii cells was observed.

Clinical and pathologic changes in a guinea pig aerosol challenge model of acute Q fever.

Acute Q fever is a zoonotic disease caused by the obligate intracellular bacterium Coxiella burnetii and can manifest as a flu-like illness, pneumonia, or hepatitis. A need exists in Q fever research for animal models mimicking both the typical route of infection (inhalation) and the clinical illness seen in human cases of Q fever. A guinea pig aerosol challenge model was developed using C. burnetii Nine Mile phase I (RSA 493), administered using a specialized chamber designed to deliver droplet nuclei directly to the alveolar spaces. Guinea pigs were given 10(1) to 10(6) organisms and evaluated for 28 days postinfection. Clinical signs included fever, weight loss, respiratory difficulty, and death, with the degree and duration of response corresponding to the dose of organism delivered. Histopathologic evaluation of the lungs of animals infected with a high dose showed coalescing panleukocytic bronchointerstitial pneumonia at 7 days postinfection that resolved to multifocal lymphohistiocytic interstitial pneumonia by 28 days. Guinea pigs receiving a killed whole-cell vaccine prior to challenge with the highest dose of C. burnetii were protected against lethal infection and did not develop fever. Clinical signs and pathological changes noted for these guinea pigs were comparable to those seen in human acute Q fever, making this an accurate and valuable animal model of human disease.

We encountered a family in which two of four members, the husband and his wife, had summer-type hypersensitivity pneumonitis at the same time, about two months after they moved to the residence. A 45-year-old man had cough, fever and exertional dyspnea. Chest computed tomography showed diffuse centriloblar ground-glass attenuation in both lung fields. His 43-year-old wife had chest small nodular shadows and similar symptoms to his husband. Serum anti-Tricosporon cutaneum (T. asahi: serotype II and T. mucoides: serotype I) antibodies of both patients were at the positive level. They were given diagnosis as summer-type hypersensitivity pneumonitis by radiological, serological and histological examinations. The symptoms in both cases were improved immediately after administration of systemic corticosteroid. Summer-type hypersensitivity pneumonitis was assumed to be caused for about two months duration of expousure to antigen.

We report here 2 cases of psittacosis in a pet shop. In the first case, a 44-year-old male was admitted with fever, and a chest radiograph showed an infiltration shadow in the right lower lung. One day later, a colleague of the first patient, a 42-year-old man, developed fever and was admitted. In this patient, chest radiography revealed an infiltration shadow in the left lower lung. Both patients had mild liver dysfunction. The serum titer of a complement fixation (CF) test against Chlamydia psittaci was elevated fourfold in the first case and sixteen-fold in the second on the analysis of paired acute- and convalescent-phase serum specimens. Clinical symptoms and abnormal laboratory data were attenuated by the administration of minocycline for 2 weeks. Since both patients worked in same pet shop and since some parakeets at the shop had died, we speculated that the psittacosis had originated from these birds.

Arenaviruses are enveloped single-strand RNA viruses that mostly have natural hosts in rodents. Upon infection of humans, several arenaviruses can cause severe hemorrhagic fever diseases, including Lassa fever that is endemic in West Africa. The virulence mechanism of these deadly arenaviruses can be studied in a safe and economical small animal model-guinea pigs infected by a nonpathogenic arenavirus Pichinde virus (PICV), a virulent strain of which can cause similar disease syndromes in guinea pigs as arenaviral hemorrhagic fevers in humans. We have recently developed molecular clones for both the virulent and avirulent strains of PICV. Using the available reverse genetics tools, we are characterizing the molecular determinants of virulent arenavirus infections in vivo.

This is a metastatic spread of squamous cell lung carcinoma to lungs, liver, lymph node, bone and subcutanous region as multiple abscess-like lesions. A fifty-five years old man admitted to the out-patient clinic with fever, cough, hemopthysis, night sweats, chest pain, abdominal pain and weight loss. In a short period of time abcess like lesions developed in his lungs, liver, lymph node, bone and subcutanous region. Though the clinical presentation is suggestive for an infectious condition, no success to antimicrobial treatment and negative results of microbiological studies have arised a need to further investigations. Histopathological studies of the abscess wall ultimately gave the definitive diagnosis as metastatic squamous cell carcinoma. We believe that case report is interesting because of the uncommon metastatic lesions masquerading the abscesses and also wide-spread multiple distant invasions of a squamous cell lung carcinoma in a short time period.

Information about the development of febrile neutropenia in patients with solid tumors remains insufficient. In this study, we tried to identify the risk factors for refractory febrile neutropenia in patients with lung cancer. A total of 59 neutropenic fever episodes associated with anti-tumor chemotherapy for lung cancer were retrospectively analyzed. We compared patient characteristics according to their initial response to treatment with antibiotics. For 34 of 59 (58%) episodes a response to initial antibiotics was obtained whereas 25 of 59 (42%) were refractory to treatment. Multivariate analysis demonstrated independent risk factors for refractory febrile neutropenia with lung cancer. These risk factors were the severity of febrile neutropenia (odds ratio (OR) 6.11; 95% confidence interval (CI) 1.85-20.14) and C-reactive protein more than 10 mg/dl (OR 4.39; 95% CI 1.22-15.74). These factors could predict outcome for patients with lung cancer who develop refractory febrile neutropenia.

The objective of this study was to assess whether adding cisplatin to gemcitabine/vinorelbine combination improves the clinical outcome in patients with non-small-cell lung cancer (NSCLC). Chemotherapy-naïve patients with advanced NSCLC; age < or = 75 years: Karnofsky performance status > or = 60%, and with adequate hematological, renal and hepatic function, were randomized into 2 treatment groups to receive Gemcitabine 1250 mg/m2 + vinorelbine 30 mg/m2 (GV group), or cisplatin 50 mg/m2 + gemcitabine 1000 mg/m2 + vinorelbine 25 mg/m2 (CGV group). All drugs were administered on days 1 and 8 every three weeks: From September 1999 to March 2003, 114 patients were enrolled. No statistically significant difference was observed in GV vs CGV group in objective response (37 versus 47%, respectively; P = 0.5), median time to progression (5 versus 5.8 months; P = 0.6), overall survival (9 versus 10 months; P = 0.9) and 1-year survival (26 versus 28%; P = 0.9). Conversely, toxicities were significantly higher for CGV, including grade 3-4 neutropenia (24 versus 45%); neutropenic fever (4 versus 14%, including one toxic death); grade 3-4 thrombocytopenia (2 versus 14%); and grade 3-4 emesis (2 versus 14%). Our results suggest that the combination of gemcitabine and vinorelbine is less toxic than three-drug combination with cisplatin while showing similar efficacy.

A 10-year-old boy with West syndrome was referred to hospital because of high fever and cough. Chest X-ray and computed tomography showed consolidation with an abscess in the right upper lobe. Laboratory data indicated cytokine storm. Various antibacterial agents and additional corticosteroid were unable to control the hypercytokinemia, which was suppressed after cyclosporine A was started. The lung abscess remained, however, and right upper lobectomy was performed. Culture from the abscess showed no growth, while polymerase chain reaction assay indicated Mycoplasma pneumoniae DNA. Serum passive agglutinin titer for M. pneumoniae was significantly elevated in the convalescent phase. These findings are strong evidence that the lung abscess was caused by M. pneumoniae infection. © 2015 Japan Pediatric Society.

Hemorrhagic Fever with Renal Syndrome in the New, and Hantavirus Pulmonary Syndrome in the Old World: paradi(se)gm lost or regained?

PubMed

Clement, Jan; Maes, Piet; Van Ranst, Marc

2014-07-17

Since the first clinical description in 1994 of the so-called "Hantavirus Pulmonary Syndrome" (HPS) as a "newly recognized disease", hantavirus infections have always been characterized as presenting in two distinct syndromes, the so-called "Hemorrhagic Fever with Renal Syndrome" (HFRS) in the Old World, with the kidney as main target organ, in contrast to HPS in the New World, with the lung as main target organ. However, European literature mentions already since 1934 a mostly milder local HFRS form, aptly named "nephropathia epidemica" (NE), and caused by the prototype European hantavirus species Puumala virus (PUUV). Several NE reports dating from the 1980s and early 1990s described already non-cardiogenic HPS-like lung involvement, prior to any kidney involvement, and increasing evidence is now mounting that a considerable clinical overlap exists between HPS and HFRS. Moreover, growing immunologic insights point to common pathologic mechanisms, leading to capillary hyperpermeability, the cardinal feature of all hantavirus infections, both of the New and Old World. It is now perhaps time to reconsider the paradigm of two "different" syndromes caused by viruses of the same Hantavirus genus in the same Bunyaviridae family, and to agree on a common, more logical disease denomination, such as simply and briefly "Hantavirus fever".

Management of Postoperative Fever in Adult Cardiac Surgical Patients.

PubMed

O'Mara, Susan K

Postoperative fever after cardiac surgery is a common occurrence. Most fevers are benign and self-limiting resulting from inflammation caused by surgical trauma and blood contact with cardiopulmonary bypass circuit resulting in the release of cytokines. Only a small percentage of time is postoperative fever due to an infection complicating surgery. The presence of fever frequently triggers a battery of diagnostic tests that are costly, could expose the patient to unnecessary risks, and can produce misleading or inconclusive results. It is therefore important that fever be evaluated in a systematic, prudent, clinically appropriate, and cost-effective manner. This article focuses on the current evidence regarding pathophysiology, incidence, causes, evaluation, and management of fever in postoperative adult cardiac surgical patients.

This study aims to describe the unique characteristics of absorption fever in patients with a hematoma after percutaneous renal biopsy (PRB) and distinguish it from secondary infection of hematoma.We retrospectively studied 2639 percutaneous renal biopsies of native kidneys. We compared the clinical characteristics between 2 groups: complication group (gross hematuria and/or perirenal hematoma) and no complication group. The axillary temperature of patients with a hematoma who presented with fever was measured at 06:00, 10:00, 14:00, and 18:00. The onset and duration of fever and the highest body temperature were recorded. Thereafter, we described the time distribution of absorption fever and obtained the curve of fever pattern.Of 2639 patients, PRB complications were observed in 154 (5.8%) patients. Perirenal hematoma was the most common complication, which occurred in 118 (4.5%) of biopsies, including 74 small hematoma cases (thickness ≤3 cm) and 44 large hematoma cases (thickness >3 cm). Major complications were observed in only 6 (0.2%) cases resulting from a large hematoma. Of 118 patients with a perirenal hematoma, absorption fever was observed in 48 cases. Furthermore, large hematomas had a 5.23-fold higher risk for absorption fever than the small ones.Blood pressure, renal insufficiency, and prothrombin time could be risk factors for complications. Fever is common in patients with hematoma because of renal biopsy and is usually noninfectious. Evaluation of patients with post-biopsy fever is necessary to identify any obvious infection sources. If no focus is identified, empiric antibiotic therapy should not be initiated nor should prophylactic antibiotics be extended for prolonged durations. Absorption fevers will resolve in time without specific therapeutic interventions.

Sun, Lisa R; Huisman, Thierry A G M; Yeshokumar, Anusha K; Johnston, Michael V

2015-11-01

Rocky Mountain spotted fever is a tickborne infection that produces a systemic small-vessel vasculitis; its prognosis is excellent if appropriate treatment is initiated early. Because the advent of effective antirickettsial therapies predates the widespread use of brain magnetic resonance imaging, there are limited data on the effect of untreated Rocky Mountain spotted fever infection on neuroimaging studies. We describe a 7-year-old girl with delayed treatment of Rocky Mountain spotted fever who suffered severe neurological impairment. Serial brain magnetic resonance images revealed a progressive "starry sky appearance," which is proposed to result from the same small vessel vasculitis that causes the characteristic skin rash of this infection. Neurological injury can continue to occur despite specific antirickettsial therapy in Rocky Mountain spotted fever. This child's clinical features raise questions about the optimal management of this infection, particularly the utility of immune modulating therapies in cases of delayed treatment and neurological involvement.

Preliminary Results of Bedaquiline as Salvage Therapy for Patients With Nontuberculous Mycobacterial Lung Disease

PubMed Central

Wallace, Richard J.; Benwill, Jeana L.; Taskar, Varsha; Brown-Elliott, Barbara A.; Thakkar, Foram; Aksamit, Timothy R.; Griffith, David E.

BACKGROUND: Bedaquiline is an oral antimycobacterial agent belonging to a new class of drugs called diarylquinolines. It has low equivalent minimal inhibitory concentrations for Mycobacterium tuberculosis and nontuberculous mycobacterial (NTM) lung disease, especially Mycobacterium avium complex (MAC) and Mycobacterium abscessus (Mab). Bedaquiline appears to be effective for the treatment of multidrug-resistant TB but has not been tested clinically for NTM disease. METHODS: We describe a case series of off-label use of bedaquiline for treatment failure lung disease caused by MAC or Mab. Only patients whose insurance would pay for the drug were included. Fifteen adult patients were selected, but only 10 (six MAC, four Mab) could obtain bedaquiline. The 10 patients had been treated for 1 to 8 years, and all were on treatment at the start of bedaquiline therapy. Eighty percent had macrolide-resistant isolates (eight of 10). The patients were treated with the same bedaquiline dosage as that used in TB trials and received the best available companion drugs (mean, 5.0 drugs). All patients completed 6 months of therapy and remain on bedaquiline. RESULTS: Common side effects included nausea (60%), arthralgias (40%), and anorexia and subjective fever (30%). No abnormal ECG findings were observed with a mean corrected QT interval lengthening of 2.4 milliseconds at 6 months. After 6 months of therapy, 60% of patients (six of 10) had a microbiologic response, with 50% (five of 10) having one or more negative cultures. CONCLUSIONS: This small preliminary report demonstrates potential clinical and microbiologic activity of bedaquiline in patients with advanced MAC or Mab lung disease but the findings require confirmation with larger studies.

Lung ischemia-reperfusion injury is the main cause of primary graft dysfunction after lung transplantation and results in increased morbidity and mortality. Fas-mediated apoptosis is one of the pathologic mechanisms involved in the development of ischemia-reperfusion injury. We hypothesized that the inhibition of Fas gene expression in lungs by intratracheal administration of small interfering RNA could reduce lung ischemia-reperfusion injury in an ex vivo model reproducing the procedural sequence of lung transplantation. Prospective, randomized, controlled experimental study. University research laboratory. C57/BL6 mice weighing 28-30 g. Ischemia-reperfusion injury was induced in lungs isolated from mice, 48 hours after treatment with intratracheal small interfering RNA targeting Fas, control small interfering RNA, or vehicle. Isolated lungs were exposed to 6 hours of cold ischemia (4°C), followed by 2 hours of warm (37°C) reperfusion with a solution containing 10% of fresh whole blood and mechanical ventilation with constant low driving pressure. Fas gene expression was significantly silenced at the level of messenger RNA and protein after ischemia-reperfusion in lungs treated with small interfering RNA targeting Fas compared with lungs treated with control small interfering RNA or vehicle. Silencing of Fas gene expression resulted in reduced edema formation (bronchoalveolar lavage protein concentration and lung histology) and improvement in lung compliance. These effects were associated with a significant reduction of pulmonary cell apoptosis of lungs treated with small interfering RNA targeting Fas, which did not affect cytokine release and neutrophil infiltration. Fas expression silencing in the lung by small interfering RNA is effective against ischemia-reperfusion injury. This approach represents a potential innovative strategy of organ preservation before lung transplantation.

Antiphospholipid syndrome (APS) with pleural effusion is extremely rare. A 75-year-old man was admitted to our hospital for spreading erythema on his trunk and extremities, as well as dyspnea. One year before admission, he had visited us with a 1-year history of erythema and purpura on his legs and occasional fever. Given the diagnosis of APS, we initiated a combination therapy of aspirin and warfarin, but the skin lesions had gradually worsened. A biopsy specimen revealed marked thrombosis in the dermal and subcutaneous small vessels. In addition, chest X-ray and computed tomography demonstrated a large pleural effusion in the left lung. He underwent repeated drainage of the pleural effusion but the effusion recurred. We added oral prednisolone 30 mg daily to his prior anticoagulant therapy. The skin lesions and pleural effusion rapidly improved and disappeared without any complication. Corticosteroids might be a choice of treatment for intractable pleural effusion in APS patients.

A 2- to 4-year-old uncastrated male Siberian tiger (Panthera tigris altica) bred in a local wild animal park presented with generalized clinical signs including abdominal pain, fever, lethargy, and anorexia, along with subcutaneous nodules along the trunk. The patient subsequently died of chronic, progressive dyspnea despite 45 days of antibiotic treatment. At necropsy, mesenteric fat inflammation and multiple subcutaneous, peritoneal, and intraabdominal nodules were observed. The lungs demonstrated congestion and heavy coagulation, and necrotic foci were observed on the cut surface. Histopathologically, the nodules were identified as granulomatous fatty tissue with numerous lymphocytes, infiltration with lipid-laden macrophages, and fibrosis. These changes were also noted in the lung. The etiology of this condition remains undetermined. PMID:29081476

Body temperature changes during simulated bacterial infection in a songbird: fever at night and hypothermia during the day.

Although fever (a closely regulated increase in body temperature in response to infection) typically is beneficial, it is energetically costly and may induce detrimentally high body temperatures. This can increase the susceptibility to energetic bottlenecks and risks of overheating in some organisms. Accordingly, it could be particularly interesting to study fever in small birds, which have comparatively high metabolic rates and high, variable body temperatures. We therefore investigated two aspects of fever and other sickness behaviours (circadian variation, dose dependence) in a small songbird, the zebra finch. We injected lipopolysaccharide (LPS) at the beginning of either the day or the night, and subsequently monitored body temperature, body mass change and food intake for the duration of the response. We found pronounced circadian variation in the body temperature response to LPS injection, manifested by (dose-dependent) hypothermia during the day but fever at night. This resulted in body temperature during the peak response being relatively similar during the day and night. Day-to-night differences might be explained in the context of circadian variation in body temperature: songbirds have a high daytime body temperature that is augmented by substantial heat production peaks during activity. This might require a trade-off between the benefit of fever and the risk of overheating. In contrast, at night, when body temperature is typically lower and less variable, fever can be used to mitigate infection. We suggest that the change in body temperature during infection in small songbirds is context dependent and regulated to promote survival according to individual demands at the time of infection. © 2015.

Expression of pleiotrophin in small cell lung cancer.

PubMed

Wang, H Q; Wang, J

2015-01-01

Pleiotrophin (PTN) is a kind of heparin binding growth factor closely related to tumor progression. This study aimed to discuss the significance of the expression of PTN in benign and malignant lung cancer tissues, especially small cell lung cancer. Lung cancer samples were collected for study and lung tissue samples with benign lesions were taken as controls. The expression of PTN was detected using tissue chip combined with the immunohistochemical method, and the differences of small cell lung cancer with non-small cell lung cancer and benign lesion tissue were compared. It was found that PTN expression was mainly located in the cytoplasm and membrane of cells; PTN expression in the lung cancer group was higher than that in the control group (p < 0.01), and PTN expression in the small cell cancer group was higher than that in the squamous carcinoma group and glandular cancer group (p < 0.05). In addition, PTN expression quantity in patients with lung cancer were in close correlation with TNM staging, pathological type and tumor differentiation degree (p < 0.05). PTN was found to express abnormally high in lung cancer, especially small cell lung cancer tissue. PTN is most likely to be a new tumor marker for diagnosis and prognosis of lung cancer.

Acute fibrinous and organising pneumonia.

PubMed

Gonçalves, João Rocha; Marques, Ricardo; Serra, Paula; Cardoso, Leila

2017-09-07

Acute fibrinous and organising pneumonia (AFOP) is a rare histological pattern of interstitial lung disease. The authors describe a 60-year-old woman admitted to the hospital for sustained fever, presenting with an alveolar opacity on chest X-ray, with the presumed diagnosis of community-acquired pneumonia and the onset of antibiotics. Since serological results suggested that Legionella pneumophila was the infectious agent, she was discharged on levofloxacin. A week later, she was again admitted with fever. CT scan showed opacities with crescentic morphology and a central ground-glass area suggestive of cryptogenic organising pneumonia. Microbiological, serological and autoimmunity tests were negative. She underwent surgical lung biopsy that revealed inflammatory infiltrate, macrophage desquamation, fibroblasts proliferation and fibrin deposition in the alveolar spaces, consistent with AFOP. She started corticotherapy with good response. Disease relapsed after prednisolone discontinuation, 10 months later. Currently, the patient is on prednisolone 5 mg/day without clinical and radiological recurrence. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Diagnostic dilemma: Epstein-Barr virus (EBV) infectious mononucleosis with lung involvement or co-infection with Legionnaire's disease?

PubMed

Cunha, Burke A; Gian, John

Hospitalized adults with fever and "pneumonia" can be a difficult diagnostic challenge particularly when the clinical findings may be due to different infectious diseases. We recently had an elderly female who presented with fever, fatigue and dry cough with elevated serum transaminases and lung infiltrates. The diagnosis of Epstein-Barr virus (EBV) infectious mononucleosis (IM) was made based on a positive Monospot test, elevated EBV VCA IgM titer, and highly elevated EBV viral load. Her chest infiltrates were not accompanied by hilar adenopathy which may occur with EBV IM. Her dry cough persisted and she developed abdominal pain. Legionnaire's disease was considered because she had extra-pulmonary findings characteristic of Legionnaire's disease, e.g., relative bradycardia, abdominal pain, hyponatremia, hypophosphatemia, elevated ferritin levels, microscopic hematuria. Legionella titers were negative, but Legionella (serogroup 1) urinary antigen was positive. We present a diagnostic dilemma in an elderly female with both Legionnaire's disease and Epstein-Barr virus infectious mononucleosis with pulmonary involvement. Copyright © 2016 Elsevier Inc.

The aim of this study was to assess the feasibility, efficacy and safety of a modified silicone fluted drain tube after video-assisted thoracic surgery (VATS) lung resection. The prospective randomized study included 50 patients who underwent VATS lung resection between March 2015 and June 2015. Eligible patients were randomized into two groups: experimental group (using the silicone fluted drain tubes for chest drainage) and control group (using standard drain tubes for chest drainage). The volume and characteristics of drainage, postoperative (PO) pain scores and hospital stay were recorded. All patients received standard care during hospital admission. In accordance with the exit criteria, three patients were excluded from study. The remaining 47 patients included in the final analysis were divided into two groups: experiment group (N=24) and control group (N=23). There was no significant difference between the two groups in terms of age, sex, height, weight, clinical diagnosis and type of surgical procedure. There was a trend toward less PO pain in experimental group on postoperative day (POD) 1, with a statistically significant difference. Patients in experimental group had a reduced occurrence of fever [temperature (T) >37.4 °C] compared to the control group. The silicone fluted drain tube is feasible and safe and may relieve patient PO pain and reduce occurrence of fever without the added risk of PO complications.

Marburg virus causes a highly infectious and lethal haemorrhagic fever in primates and may be exploited as a potential biothreat pathogen. To combat the infection and threat of Marburg haemorrhagic fever, there is a need to develop and license appropriate medical countermeasures. To determine whether the common marmoset (Callithrix jacchus) would be an appropriate model to assess therapies against Marburg haemorrhagic fever, initial susceptibility, lethality and pathogenesis studies were performed. Low doses of virus, between 4 and 28 TCID50, were sufficient to cause a lethal, reproducible infection. Animals became febrile between days 5 and 6, maintaining a high fever before succumbing to disease between 8 and 11 days postchallenge. Typical signs of Marburg virus infection were observed including haemorrhaging and a transient rash. In pathogenesis studies, virus was isolated from the animals’ lungs from day 3 postchallenge and from the liver, spleen and blood from day 5 postchallenge. Early signs of histopathology were apparent in the kidney and liver from day 3. The most striking features were observed in animals exhibiting severe clinical signs, which included high viral titres in all organs, with the highest levels in the blood, increased levels in liver function enzymes and blood clotting times, decreased levels in platelets, multifocal moderate-to-severe hepatitis and perivascular oedema.

Rift Valley fever virus (RVFV) is an emerging virus that causes serious illness in humans and livestock. There are no approved vaccines or treatments for humans. The purpose of the study was to identify inhibitory compounds of RVFV infection without any preconceived idea of the mechanism of action. A whole-cell-based high-throughput drug screening assay was developed to screen 28,437 small chemical compounds targeting RVFV infection. To accomplish both speed and robustness, a replication-competent NSs-deleted RVFV expressing a fluorescent reporter gene was developed. Inhibition of fluorescence intensity was quantified by spectrophotometry and related to virus infection in human lung epithelial cells (A549). Cell toxicity was assessed by the Resazurin cell viability assay. After primary screening, 641 compounds were identified that inhibited RVFV infection by ≥80%, with ≥50% cell viability at 50 µM concentration. These compounds were subjected to a second screening regarding dose-response profiles, and 63 compounds with ≥60% inhibition of RVFV infection at 3.12 µM compound concentration and ≥50% cell viability at 25 µM were considered hits. Of these, six compounds with high inhibitory activity were identified. In conclusion, the high-throughput assay could efficiently and safely identify several promising compounds that inhibited RVFV infection. © 2016 Society for Laboratory Automation and Screening.

A 72-year-old man had underwent left lower lobectomy for squamous cell carcinoma in our hospital in 2008. Postoperative stage was I A (T1N0M0). In 2010, follow-up chest computed tomography (CT) images showed similar cavitary nodules in segments 2 and 8 of the right lung with positive uptake on fluorodeoxyglucose-positron emission tomography (FDG-PET) images. Physical examination, blood tests, and levels of serum tumor markers showed no abnormality. Transbronchial lung biopsy revealed the absence of malignant cells. Segment 8 of the right lower lobe with the nodule was partially resected, and pathological examination demonstrated lung abscess. He was discharged but was hospitalized in another hospital for purpuric rash, fever, and arthralgia. Microscopic albuminuria was noted, and renal biopsy revealed nephritis with immunoglobulin A( IgA)deposition. He was made a diagnosis of Henoch-Schönlein purpura. Oral steroid therapy( prednisolone 60 mg/d) was initiated, resulting in the improvement of symptoms and disapearance of the cavitary nodule in the right lung segment 2.

We report a case of lung abscess misdiagnosed as adenocarcinoma based on cytologic findings of the sample obtained from needle biopsy. A 45-year-old man consulted our hospital because of fever, wet cough and an abnormal shadow on a chest X-ray film. A chest computed tomography revealed gradually enlarging pulmonary mass in the left S6 infiltrating the S5. A diagnosis of lung cancer was suspected and surgery was performed. Pathological findings of the specimen showed atypical cells with a large nucleus and a gross papillary neoplasm by needle biopsy. The patient underwent left lower lobectomy and partial resection of upper lobe with standard nodal dissection. The final diagnosis was a lung abscess with pneumonia without evidence of malignancy. When an indeterminate pulmonary tumor must be diagnosed during an operation, we should perform partial resection if possible.

Effects of aspirin on small-cell lung cancer mortality and metastatic presentation.

PubMed

Maddison, Paul

2017-04-01

Although meta-analysis data have shown that taking regular aspirin may reduce lung cancer mortality, individual trial data results are conflicting, and the data on the effects of aspirin on different histological subtypes of lung tumours, in particular small-cell lung cancer, are sparse. We conducted a prospective observational study of 313 patients with a new diagnosis of small-cell lung cancer and recorded use of aspirin before and after tumour diagnosis. Seventy-one (23%) patients were taking regular daily aspirin for more than 2 years at the time of tumour diagnosis. We found that regular use of aspirin had no effect on survival nor metastatic presentation compared to data from small-cell lung cancer patients not taking aspirin. The lack of survival benefit in patients with small-cell lung cancer taking long-term aspirin may be due to the low expression of cyclooxygenase-2 in small-cell lung cancer tissue.

Symptoms include fever, headache, muscle and joint pains, and a characteristic skin rash that is similar to measles. In a small proportion of cases, the disease develops into life-threatening dengue hemorrhagic fever, which results in bleeding, thrombocytopenia, and leakage of blood plasma, or into dengue shock syndrome, in which dangerously low blood pressure occurs. Treatment of acute dengue fever is supportive, with either oral or intravenous rehydration for mild or moderate disease and use of intravenous fluids and blood transfusion for more severe cases. Along with attempts to eliminate the mosquito vector, work is ongoing to develop a vaccine and medications targeted directly at the virus.

Non-small-cell lung cancer is one of the most lethal cancers in the worldwide. Although Paclitaxel-based combinational therapies have long been used as a standard treatment in aggressive non-small-cell lung cancers, Paclitaxel resistance emerges as a major clinical problem. It has been demonstrated that Curcumin from Curcuma longa as a traditional Chinese medicine can inhibit cancer cell proliferation. However, the role of Curcumin in Paclitaxel-resistant non-small-cell lung cancer cells is not clear. In this study, we investigated the effect of Curcumin on the Paclitaxel-resistant non-small-cell lung cancer cells and found that Curcumin treatment markedly increased the sensitivity of Paclitaxel-resistant non-small-cell lung cancer cells to Paclitaxel. Mechanically, the study revealed that Curcumin could reduce the expression of metastasis-associated gene 1 (MTA1) gene through upregulation of microRNA-30c in Paclitaxel-resistant non-small-cell lung cancer cells. During the course, MTA1 reduction sensitized Paclitaxel-resistant non-small-cell lung cancer cells and enhanced the effect of Paclitaxel. Taken together, our studies indicate that Curcumin increases the sensitivity of Paclitaxel-resistant non-small-cell lung cancer cells to Paclitaxel through microRNA-30c-mediated MTA1 reduction. Curcumin might be a potential adjuvant for non-small-cell lung cancer patients during Paclitaxel treatment.

A 68-year-old man was referred to our hospital due to general fatigue, fever and weight loss. His chest radiograph showed a nodule (2.8 cm) in the right middle lobe. Computed tomography and positron emission tomography showed multiple metastases to the bone, liver and lymph nodes. The lung nodule was not accessible by standard transbronchial forceps. However, biopsy specimens obtained using Sasada Transbronchial Angled Biopsy Forceps (STAF) pathologically confirmed the diagnosis of malignant lymphoma. We report the case, and discuss the utility of STAF for lung lesions that are difficult to access with standard forceps.

Cryptogenic organizing pneumonia (COP) is a rare pulmonary disorder of unknown etiology. COP with hemoptysis as the primary presenting symptom has rarely been reported. The present study reported a case of COP that resembled lung carcinoma with hemoptysis as the only clinical symptom. The patient recovered well following thoracoscope surgery. A literature review of 119 COP cases between 1995 and 2015 was presented. Cough, fever and dyspnea were the most common clinical manifestations. The most common imaging manifestations were multiple or single consolidation, lung nodules, migratory sign, reversed halo sign, and multiple ground-glass opacity. A total of 3 cases exhibited COP accompanied by lung cancer. Glucocorticoids were effective for the majority of cases and invasive surgeries were implemented in most cases. The majority of cases recovered or relieved, and the prognosis of COP was relatively good. COP was easily confused with lung tumor and it is necessary to make differential diagnosis between COP and lung cancer. Invasive surgery should be avoided when possible to avoid or reduce patient trauma. PMID:29399056

Lassa fever afflicts tens of thousands of people in West Africa annually. The rapid progression of patients from febrile illness to fulminant syndrome and death provides incentive for development of clinical prognostic markers that can guide case management. The small molecule profile of serum from febrile patients triaged to the Viral Hemorrhagic Fever Ward at Kenema Government Hospital in Sierra Leone was assessed using untargeted Ultra High Performance Liquid Chromatography Mass Spectrometry. Physiological dysregulation resulting from Lassa virus (LASV) infection occurs at the small molecule level. Effects of LASV infection on pathways mediating blood coagulation, and lipid, amino acid, nucleic acid metabolism are manifest in changes in the levels of numerous metabolites in the circulation. Several compounds, including platelet activating factor (PAF), PAF-like molecules and products of heme breakdown emerged as candidates that may prove useful in diagnostic assays to inform better care of Lassa fever patients.

2015-11-27

The expanding distribution of African swine fever (ASF) is threatening the pig industry worldwide. Most outbreaks occur in backyard and small-scale herds, where poor farmers often attempt to limit the disease's economic consequences by the emergency sale of their pigs. The risk of African swine fever virus (ASFV) release via this emergency sale was investigated. Simulation modeling was used to study ASFV transmission in backyard and small-scale farms as well as the emergency sale of pigs, and the potential impact of improving farmers and traders' clinical diagnosis ability-its timeliness and/or accuracy-was assessed. The risk of ASFV release was shown to be high, and improving farmers' clinical diagnosis ability does not appear sufficient to effectively reduce this risk. Estimates obtained also showed that the distribution of herd size within the backyard and small-scale sectors influences the relative contribution of these farms to the risk of release of infected pigs. These findings can inform surveillance and control programs.

Non-small cell lung cancer is the most common malignancy in males; it constitutes the majority of lung cancer cases and requires massive medical resources. Despite improvements in managing non-small cell lung cancer, long-term survival remains very low. This study evaluated survival improvement in patients with non-small cell lung cancer in each decade between 1983 and 2012 to determine the impact of race, sex, age, and socioeconomic status on the survival rates in these patients. We extracted data on non-small cell lung cancer cases in each decade between 1983 and 2012 from the Surveillance, Epidemiology, and End Results registries. In total, 573,987 patients with non-small cell lung cancer were identified in 18 Surveillance, Epidemiology, and End Results registry regions during this period. The 12-month relative survival rates improved slightly across three decades, from 39.7% to 40.9% to 45.5%, with larger improvement in the last two decades. However, the 5-year-relative survival rates were very low, with 14.3%, 15.5%, and 18.4%, respectively, in three decades, indicating the urgency for novel comprehensive cancer care. In addition, our data demonstrated superiority in survival time among non-small cell lung cancer patients of lower socioeconomic status and White race. Although survival rates of non-small cell lung cancer patients have improved across the three decades, the 5-year-relative survival rates remain very poor. In addition, widening survival disparities among the race, the sex, and various socioeconomic status groups were confirmed. This study will help in predicting future tendencies of incidence and survival of non-small cell lung cancer, will contribute to better clinical trials by balancing survival disparities, and will eventually improve the clinical management of non-small cell lung cancer.

The incidence of gastrointestinal metastases from lung cancer is higher than previously thought as they have been reported in 2-14% of the cases in autopsy studies. However, clinically significant metastases are rare. Small bowel perforation secondary to metastatic non-small cell lung cancer is a very rare clinical entity. The aim of this study is to describe a case of ileal perforation in a patient with intestinal metastases of a non-small cell lung cancer, along with a review of the literature. A 57-year-old male with a history of non-small cell lung cancer was referred to our emergency department with signs and symptoms of acute surgical abdomen. A computed tomography scan demonstrated dilated small bowel loops, liver deposits, and signs of perforation of an intra-abdominal hollow viscus. Emergency exploratory laparotomy revealed diffuse purulent peritonitis and a perforated ileal tumor. A segmental small bowel resection and primary anastomosis were performed. Histological and immunohistochemical findings were consistent with a metastatic non-small cell lung carcinoma. Additional evaluation revealed widespread metastatic disease. Unfortunately, despite adjuvant treatment, the patient died of progressive disease 2 months after surgery. Small bowel perforation due to metastatic non-small cell lung cancer is a very rare clinical entity. The possibility of small bowel metastases should be kept in mind in patients with lung cancer presenting with an acute abdomen. Intestinal perforation occurs in advanced stages and is usually a sign of widespread disease. Aggressive surgery can provide effective palliation and may improve short-term survival. The prognosis is however dismal.

There exists few pediatric data on the safety and efficacy of prophylactic antibiotics during chemotherapy-induced agranulocytosis. We prospectively studied the incidence of infection-related fever in 38 children, aged 2-16 years, with acute myeloid leukemia (AML) over 121 chemotherapy treatment cycles. A prophylactic group (n = 18) was given either vancomycin/cefepime (400 mg/m(2), q12 h/50 mg/kg, q12 h) or piperacillin/tazobactam (110 mg/kg, q12 h). Control patients (n = 20) received no preventive antibiotics. The prophylactic group (59 treatment cycles) experienced fever less frequently than the control group (0.4 vs. 0.9 events; p < 0.001), had a longer interval between agranulocytosis and fever (6.4 vs. 3.8 days; p = 0.007), had a shorter duration of hospitalization (21.5 vs. 28.5 days; p < 0.001), and had a lower rate of lung infection (38.8 vs. 80.0%; p < 0.001). One patient taking vancomycin experienced a skin rash and 3 patients taking piperacillin/tazobactam had diarrhea; these side effects subsided after antibiotics were discontinued. In children with AML, prophylactic antibiotics during the period of chemotherapy-induced agranulocytosis can effectively reduce the incidence of infectious fever and can shorten the average length of hospital stay, improving treatment success and quality of life. © 2014 S.

Marburg virus causes a highly infectious and lethal haemorrhagic fever in primates and may be exploited as a potential biothreat pathogen. To combat the infection and threat of Marburg haemorrhagic fever, there is a need to develop and license appropriate medical countermeasures. To determine whether the common marmoset (Callithrix jacchus) would be an appropriate model to assess therapies against Marburg haemorrhagic fever, initial susceptibility, lethality and pathogenesis studies were performed. Low doses of virus, between 4 and 28 TCID50 , were sufficient to cause a lethal, reproducible infection. Animals became febrile between days 5 and 6, maintaining a high fever before succumbing to disease between 8 and 11 days postchallenge. Typical signs of Marburg virus infection were observed including haemorrhaging and a transient rash. In pathogenesis studies, virus was isolated from the animals' lungs from day 3 postchallenge and from the liver, spleen and blood from day 5 postchallenge. Early signs of histopathology were apparent in the kidney and liver from day 3. The most striking features were observed in animals exhibiting severe clinical signs, which included high viral titres in all organs, with the highest levels in the blood, increased levels in liver function enzymes and blood clotting times, decreased levels in platelets, multifocal moderate-to-severe hepatitis and perivascular oedema. © 2013 Crown copyright.

Li, Xin; Hu, Bin; Miao, Jinbai

2016-01-01

Background The aim of this study was to assess the feasibility, efficacy and safety of a modified silicone fluted drain tube after video-assisted thoracic surgery (VATS) lung resection. Methods The prospective randomized study included 50 patients who underwent VATS lung resection between March 2015 and June 2015. Eligible patients were randomized into two groups: experimental group (using the silicone fluted drain tubes for chest drainage) and control group (using standard drain tubes for chest drainage). The volume and characteristics of drainage, postoperative (PO) pain scores and hospital stay were recorded. All patients received standard care during hospital admission. Results In accordance with the exit criteria, three patients were excluded from study. The remaining 47 patients included in the final analysis were divided into two groups: experiment group (N=24) and control group (N=23). There was no significant difference between the two groups in terms of age, sex, height, weight, clinical diagnosis and type of surgical procedure. There was a trend toward less PO pain in experimental group on postoperative day (POD) 1, with a statistically significant difference. Patients in experimental group had a reduced occurrence of fever [temperature (T) >37.4 °C] compared to the control group. Conclusions The silicone fluted drain tube is feasible and safe and may relieve patient PO pain and reduce occurrence of fever without the added risk of PO complications. PMID:26941976

Prostaglandin E1 fever induced in rabbits

1. Micro-injections of prostaglandin E1 (PGE1) into the anterior hypothalamus of the rabbit produced fever which was nearly immediate in onset. The prostaglandin sensitive region appears to be identical to that described as being fever sensitive to leucocytic pyrogen. 2. Micro-injections of PGE1 into the posterior hypothalamus and midbrain reticular formation of the rabbit did not produce fever. 3. The febrile response to PGE1 injected into the anterior hypothalamus was dose dependent over a range of 20-1000 ng. 4. Ambient temperature influenced the thermoregulatory mechanism by which PGE1 fever evolved. In the cold, PGE1 fever was due to increased heat production while during heat exposure both evaporative and dry heat losses were reduced without significant changes in heat production. Vasoconstriction, confined mainly to the ears, was effective in producing fever in standard room environments (24-25° C) along with a small increase in heat production. 5. The preoptic anterior hypothalamic area retained its thermosensitivity during PGE1 fever; heating this area attenuated, while cooling augmented the fever. 6. The results support the view that PGE1 is a mediator of pyrogen induced fever. ImagesFig. 2 PMID:4733481

Endothelial progenitor cells are capable of contributing to neovascularization in tumours. In patients with either malignant or transudative pleural effusion, we tested the presence of pleural endothelial progenitor cells. We also measured the number of endothelial progenitor cells in post-surgery pleural drainage of either patients with early non-small-cell lung cancer or control patients with benign lung disease undergoing pulmonary resection. The prospective influence of post-surgery pleural-drainage endothelial progenitor cells on cancer recurrence/survival was investigated. Pleural endothelial progenitor cell levels were quantified by fluorescence-activated cell sorting analysis in pleural effusion of 15 patients with late-stage non-small-cell lung cancer with pleural involvement and in 15 control patients with congestive heart failure. Also, pleural-drainage endothelial progenitor cells were measured in pleural-drainage fluid 48 h after surgery in 64 patients with early-stage non-small-cell lung cancer and 20 benign lung disease patients undergoing pulmonary resection. Cancer recurrence and survival was evaluated in patients with high pleural-drainage endothelial progenitor cell levels. The number of pleural endothelial progenitor cells was higher in non-small-cell lung cancer pleural effusion than in transudative pleural effusion. Also, pleural-drainage endothelial progenitor cell levels were higher in patients with non-small-cell lung cancer than in patients with benign lung disease undergoing pulmonary resection (P < 0.05). Non-small-cell lung cancer patients with high pleural-drainage endothelial progenitor cell levels had a significantly 4.9 higher rate of cancer recurrence/death than patients with lower pleural-drainage endothelial progenitor cell levels, irrespective of confounders. Endothelial progenitor cells are present in the pleural effusion and are higher in patients with late-stage non-small-cell lung cancer with pleural involvement than in congestive heart failure patients. Endothelial progenitor cell levels are higher in the post-surgery pleural drainage of patients with non-small-cell lung cancer than in non-neoplastic pleural-drainage fluid. High pleural-drainage endothelial progenitor cell levels in patients undergoing pulmonary resection for early non-small-cell lung cancer predict an increased risk of cancer recurrence and death. © The Author 2016.

We report a case of a 38-year-old woman who was diagnosed with stage IV lung adenocarcinoma, harboring an epidermal growth factor receptor (EGFR) L858R mutation on exon 21 and a T790 M mutation on exon 20. The patient was treated with osimertinib, a third-generation EGFR tyrosine kinase inhibitor (EGFR-TKI) following treatment with nivolumab, an anti-Programmed Cell Death 1 (anti-PD1) antibody. After initiating osimertinib treatment, the patient began to complain of low-grade fever and shortness of breath without hypoxemia, and her chest radiograph and a CT scan revealed a remarkable antitumor response, although faint infiltrations were observed in the bilateral lung field. Bronchoalveolar lavage fluid mainly contained lymphocytes (CD4+/CD8+ ratio of 0.3), and a transbronchial lung biopsy specimen showed lymphocytic alveolitis with partial organization in several alveolar spaces. Therefore we diagnosed the patient with osimertinib-induced interstitial lung disease (ILD) after treatment with anti-PD1 antibody. We considered anti-PD1 therapies may be the risk factor of EGFR-TKI-induced ILD.

To the best of our knowledge, the formation of a retroperitoneal abscess due to acute appendicitis shortly after administration of chemotherapy for lung cancer has not been previously reported. This is the case report of a 59-year-old male who was admitted to the Mito Medical Center (Mito, Japan) and diagnosed with lung adenocarcinoma with pleuritis carcinomatosis. Although no distant metastasis was identified, combination chemotherapy with cisplatin and pemetrexed was administered. Nine days after initiating chemotherapy, the patient developed right lower quadrant abdominal pain and high fever. Computed tomography (CT) of the abdomen and pelvis revealed the collection of gas and fluid in the retroperitoneum adjacent to the cecum. The abscess was locally drained; however, the infection continued to spread, with subsequent development of a scrotal abscess. Consequently, appendectomy was performed. The patient recovered well and the lung adenocarcinoma was treated with additional courses of chemotherapy following the remission of the local inflammation. Retroperitoneal abscess due to acute appendicitis is an unusual finding; however, this rare complication should be considered during or shortly after chemotherapy in patients with lung cancer.

Epidemiological studies show that people with low level of total cholesterol have a greater risk of death due to cancer, predominantly lung cancer. The aim of our study was to evaluate serum level of LDL cholesterol and lipoprotein electrophoresis pattern in patients with small cell lung cancer and their dependence on clinical stage of the neoplasm. The studied group consisted of 34 patients with newly diagnosed small cell lung cancer and 39 healthy controls. Fasting level of LDL cholesterol was analyzed and lipoprotein electrophoresis was performed. There were no statistically significant differences of evaluated serum lipid parameters between lung cancer patients and controls, and between the clinical stages of small cell lung cancer.

Limited data exist on methods to evaluate allograft function in infant recipients of lung and heart-lung transplants. At our institution, we developed a procedural protocol in coordination with pediatric anesthesia where infants were sedated to perform infant pulmonary function testing, computed tomography imaging of the chest, and flexible fiberoptic bronchoscopy with transbronchial biopsies. A retrospective review was performed of children aged younger than 1 year who underwent lung or heart-lung transplantation at our institution to assess the effect of this procedural protocol in the evaluation of infant lung allografts. Since 2005, 5 infants have undergone thoracic transplantation (3 heart-lung, 2 lung). At time of transplant, the mean ± standard deviation age was 7.2 ± 2.8 months (range, 3-11 months). Of 24 procedural sessions performed to evaluate lung allografts, 83% (20 of 24) were considered surveillance where the patients were completely asymptomatic. Of the surveillance procedures, 80% were performed as an outpatient, whereas 20% were done as inpatients during the lung or heart-lung transplant post-operative period before discharge home. Sedation was performed with propofol alone (23 of 24) or in addition to ketamine (1 of 24) infusion; mean sedation time was 141 ± 39 minutes (range, 70-214) minutes. Of the 16 outpatient procedures, patients were discharged after 14 (88%) on the same day, and after 2 (12%) were admitted for observation, with 1 being due to transportation issues and the other due to fever during the observation period. A comprehensive procedural protocol to evaluate allograft function in infant lung and heart-lung transplant recipients was performed safely as an outpatient.

Splenic abcess is an uncommon complication for cancer treatment. It occurs more frequently in immunocompromised patients. They are characterized by high mortality. The classic triad (fever, pain of the left hypochondrium, and sensitive mass left) is only present in one-third of cases the clinical spectrum ranging from no symptoms to events such as fever, nausea, vomiting, weight loss, abdominal pain left, splenomegaly. Treatment options are limited, but must be discussed and adapted to the patient profile. We report the case of a 62-year-old Arabic male, diagnosed with metastatic lung adenocarcinoma, who, after several cycles of chemotherapy, presented symptoms and signs of splenic abcess. Splenic abcess is rare situation, which must be actively researched, to have access to an optimal therapeutic approach.

We report what is believed to be the first case of pulmonary Actinomyces graevenitzii infection presenting as organizing pneumonia. Fever and night sweats developed in a 69-year-old male. The only abnormal laboratory data were an elevated erythrocyte sedimentation rate and C-reactive protein level. On chest images, multiple consolidations with air bronchograms were seen in the bilateral lungs. Histological examination from lung biopsy revealed a pattern of organizing pneumonia with microabscesses, but definitive diagnosis was not obtained because culture from lung specimen was negative. A. graevenitzii was eventually identified in the lung biopsy specimen by detection of an Actinomyces-specific PCR product followed by 16S rRNA gene sequencing. The patient was treated with high-dose ampicillin intravenously for 1 month, followed by oral amoxicillin and clarithromycin for 6 months, and recovered. We suggest that actinomycosis can present as organizing pneumonia, and identification of infection by PCR analysis and rRNA gene sequencing is a useful strategy in cases that are difficult to diagnose.

Pulmonary toxoplasmosis is a serious pulmonary condition caused by the protozoan Toxoplasma gondii It typically affects immunocompromised patients presenting acutely with cough, fever, myalgias, arthralgias and lymphadenopathy, and chronically with persistent cough and dyspnoea. Because of its protean features, it can mimic many more common lung conditions in the immunocompromised patient, including atypical pneumonia, Pneumocystis pneumonia and interstitial lung disease. In this article, we present the case of a 55-year-old woman who presented to our hospital with persistent dyspnoea and cough, initially suspected to have an arthritis-related interstitial lung disease. She received a final diagnosis of pulmonary toxoplasmosis after lung biopsy demonstrated Toxoplasma cysts, later confirmed by serology. Treatment with trimethoprim-sulfamethoxazole resulted in significant improvement of her respiratory symptoms after 3 months. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Serum tumor markers play important roles in diagnosis, response and prognosis monitoring for lung cancer. The clinical significance of serum level of tissue polypeptide specific antigen (TPS) was investigated in diagnosis, response monitoring and prognosis in patients with lung cancer, compared with carcinoembryonic antigen (CEA), precursor of gastrin-releasing peptide (Pro-GRP) and cytokeratin-19-fragments (CYFRA21-1). Blood samples of eighty-two patients with lung cancer before treatment and some after chemotherapy were measured by ELISA for four tumor markers. Compared with lung benign diseases group and health control group, the positive rates and levels of TPS, CEA and Pro-GRP in patients with lung cancer were higher, with statistically significant difference. TPS in extensive-small cell lung cancer was significant higher than that in limited-small cell lung cancer. The positive rates and levels of TPS, CEA and Pro-GRP in patients after treatment had significant decreases compared with before treatment. TPS was an independent prognostic factor of non-small cell lung cancer. TPS is valuable to diagnosis, response monitoring for patients with lung cancer, moreover, it maybe a useful factor of prognosis of non-small cell lung cancer.

The optimal chemotherapy regimen for non-small cell lung cancer patients with interstitial lung disease is unclear. We therefore investigated the safety and efficacy of carboplatin plus nab-paclitaxel as a first-line regimen for non-small cell lung cancer in patients with interstitial lung disease. We retrospectively reviewed advanced non-small cell lung cancer patients with interstitial lung disease who received carboplatin plus nab-paclitaxel as a first-line chemotherapy regimen at Hyogo Cancer Center between February 2013 and August 2016. interstitial lung disease was diagnosed according to the findings of pretreatment chest high-resolution computed tomography. Twelve patients were included (male, n = 11; female, n = 1). The overall response rate was 67% and the disease control rate was 100%. The median progression free survival was 5.1 months (95% CI: 2.9-8.3 months) and the median overall survival was 14.9 months (95% CI: 4.8-not reached). A chemotherapy-related acute exacerbation of interstitial lung disease was observed in one patient; the extent of this event was Grade 2. There were no treatment-related deaths. Carboplatin plus nab-paclitaxel, as a first-line chemotherapy regimen for non-small cell lung cancer, showed favorable efficacy and safety in patients with preexisting interstitial lung disease. © The Author 2017.

Primary lung abscess caused by Staphylococcus lugdunensis.

PubMed

Chou, Deng-Wei; Lee, Chao-Tai

2017-11-01

Staphylococcus lugdunensis, a strain of coagulase-negative staphylococci, is part of the normal flora of human skin but can cause multiple infections at various sites. This microorganism has emerged as a major human pathogen. However, no study has reported primary lung abscess caused by S. lugdunensis. A 54-year-old alcoholic man without relevant past medical history was admitted because of primary lung abscesses. Empirical amoxicillin/clavulanate therapy was initially administered; however, the patient had persistent pleuritic chest pain and fever. He subsequently underwent resection of the lung abscess and removal of exudative pleural effusion on the fourth hospital day. Histopathologic examination confirmed the diagnosis of lung abscess, and colonies of gram-positive bacteria were identified. The culture specimen from the abscess was positive for S. lugdunensis, which was susceptible to amoxicillin/clavulanate, cefazolin, ciprofloxacin, clindamycin, erythromycin, oxacillin, teicoplanin, tetracycline, and vancomycin. Following resection and 3 weeks of amoxicillin/clavulanate therapy, the patient eventually recovered well without relapse. This case report is the first to describe S. lugdunensis as a cause of primary lung abscess; this microorganism should be considered a potential monomicrobial pathogen in primary lung abscess.

This study was performed to retrospectively evaluate the 10-year overall survival (OS), progression-free survival (PFS), and local control rates of patients with inoperable stage Ia non-small cell lung cancer (NSCLC) who underwent computed tomography (CT)-guided radiofrequency ablation (RFA) in a single center. Fifty patients with inoperable NSCLC underwent RFA between 2004 and 2016. Thoracic surgeons evaluated the patients and performed RFA under CT guidance. Follow-up CT and positron emission tomography/CT scans were obtained. Local control rates and recurrence patterns were analyzed. Seventy-three lesions in 50 patients (M:F = 22:28; median age: 73 years; range: 52-82 years) were treated with CT-guided RFA. The mean lesion size was 2.2 cm (range: 1-3 cm). No procedure-related deaths occurred. Low-grade fever was the most common post-ablation complication, with an incidence rate of 36%. The 1-, 2-, 3-, 5-, and 10-year OS rates of patients with Ia NSCLC were 96.0%, 86.5%, 67.1%, 36.3%, and 1%, respectively, and the 1-, 2-, 3-, and 5-year PFS rates were 94.0%, 77.5%, 43.5%, and 10.8%, respectively. The most common pattern of recurrence was local, and 15 patients with recurrence were treated with repeat RFA. Tumor size <2.0 cm was associated with a significantly improved 3-year survival rate of 78.9%. CT-guided RFA is feasible and well tolerated by inoperable patients with inoperable stage Ia NSCLC.

A Q-fever outbreak occurred in an urban area in the south of the Netherlands in May 2008. The distribution and timing of cases suggested a common source. We studied the spatial relationship between the residence locations of human cases and nearby small ruminant farms, of which one dairy goat farm had experienced abortions due to Q-fever since mid April 2008. A generic geographic information system (GIS) was used to develop a method for source detection in the still evolving major epidemic of Q-fever in the Netherlands. All notified Q-fever cases in the area were interviewed. Postal codes of cases and of small ruminant farms (size >40 animals) located within 5 kilometres of the cluster area were geo-referenced as point locations in a GIS-model. For each farm, attack rates and relative risks were calculated for 5 concentric zones adding 1 kilometre at a time, using the 5-10 kilometres zone as reference. These data were linked to the results of veterinary investigations. Persons living within 2 kilometres of an affected dairy goat farm (>400 animals) had a much higher risk for Q-fever than those living more than 5 kilometres away (Relative risk 31.1 [95% CI 16.4-59.1]). The study supported the hypothesis that a single dairy goat farm was the source of the human outbreak. GIS-based attack rate analysis is a promising tool for source detection in outbreaks of human Q-fever.

A previously healthy 67-year-old woman visited our institution because of cough that had persisted for 3 months, fever at night, left tinnitus, and hearing loss from 1 month prior. She lost 2 kg in weight over the last 6 months, and her C-reactive protein level and leukocyte count were increased. Computed tomography revealed multiple small nodules in both lung fields. She was admitted to our hospital for further examination to determine the optimal medical treatment. Because the myeloperoxidase antineutrophil cytoplasmic antibody (ANCA) titer was 132.5 U/mL and microscopic hematuria was observed, vasculitis was considered. A percutaneous kidney biopsy was performed and revealed microscopic polyangiitis. For this reason, the case was diagnosed as ANCA-associated vasculitis. Esophageal stenosis and pseudodiverticulosis were observed on upper gastrointestinal endoscopy. Pathological changes due to inflammation were observed in the biopsy and esophagography. Pulse therapy with methylprednisolone at 1,000 mg/day was administered to the patient as the first-line treatment, followed by prednisolone at 40 mg/day as remission induction treatment. Bloody urine and lung shadows disappeared, and the steroid dose was tapered at hospital discharge. The patient's hearing ability and the esophageal pathological change that was considered to be ANCA-associated vasculitis were improved. Although a few studies have reported that esophageal stenosis and pseudodiverticulosis accompany ANCA-associated vasculitis, we think that examination for the possible presence of gastrointestinal tract lesions is important.

Postoperative radiation therapy may have a detrimental effect on survival in patients with non-small cell lung cancer. We investigated the association of the lung radiation dose with the risk of death in patients treated with postoperative radiation therapy. We analyzed 178 patients with non-small cell lung cancer who received postoperative radiation therapy. The mean lung dose was calculated from dose-volume data, and we categorized patients into the high and low lung dose groups using 2 different methods; (1) simple grouping using the median lung dose of all patients, and (2) stratified grouping using the median lung dose of each subgroup sharing the same confounders. We compared clinical variables, and survival between the high and low lung dose groups. In the simple grouping, there were no significant differences in survivals between the high and low lung dose groups. After stratification, the overall survival of low lung dose group was significantly longer than that of high lung dose group (5-year survival, 60.1% vs. 35.3%, p = 0.039). On multivariable analyses, the lung dose remained a significant prognostic factor for overall survival (hazard ratio, HR = 2.08, p = 0.019). The lung dose was associated with the risk of death in patients with non-small cell lung cancer having the same confounders. Further studies evaluating the risk of death according to the lung dose will be helpful to administer more precise and individualized postoperative radiation therapy. Copyright © 2018 Elsevier B.V.

Dr Robert Robertson (1742-1829): Fever Specialist and Philosopher-Experimenter in the Treatment of Fevers with Peruvian Bark in the Latter Eighteenth-century Royal Navy.

Short, Bruce

2015-12-01

The life and works of Dr Robert Robertson are reviewed set against the background of the extant British management of fevers during the latter 18th-century. Commencing in 1769, using the febrifuge Peruvian bark (cortex Peruvianus; Jesuit's Powder), he experimented and tested Peruvian bark mono-therapy protocols in the tropics in the cure and prevention of intermittent fever (predominantly malaria). His later work also showed the benefit of the bark in the acute care of developed continuous fevers (largely Ship Fever due to Epidemic Louse-borne Typhus Fever) in both the Temperate and Torrid Zones. In the realm of comparative statistics Robertson first demonstrated the safety and effectiveness of bark therapy against the dangerous depleting processes of the antiphlogistic regimen. He was the first to alert the Admiralty to the efficacy of bark in both the cure of acute fevers as well as a prophylactic in the tropics, and signalled the dangers of bloodletting in treating fevers of the tropics. He authored 13 books devoted to fevers outlining his theory of Febrile Infection and its treatment. The essay concludes with his role as the Physician-in-Charge of the Royal Hospital, Greenwich over a 28-year period, as an acknowledged expert in the small British group of 18th-century fever specialists.

A 55-year-old female was admitted with fever which followed an episode of pseudomembranous colitis. Despite an accurate clinical investigation, there was no evidence for specific sites of infection. Remission of fever was not obtained with antibiotic therapy (gentamycin plus carbepenem) and progressive neutropenia was observed. Neutrophils fell to 0.3 x 10(9)/1. The diagnostic approach, including a bone marrow aspirate, excluded mechanisms leading to impaired neutrophil production, and in the suspect of increased neutrophil sequestration/destruction, whole-body scintigraphy with (99m)technetium-hexamethylpropyleneamineoxime ((99m)Tc-HMPAO)-labeled autologous leukocytes was performed. As a result, a site of leukocyte sequestration localized at the medium lobe of the right lung was detected. In an attempt to enhance neutrophil functions and achieve remission of infection, recombinant human granulocyte colony-stimulating factor (Filgrastim, Granulokine 30, Roche) at the dosage of 300 microg/day, subcutaneously, was added. As a results, fever disappeared in three days, but neutrophil recovery was slower, and normalization of the absolute neutrophil count (ANC) was obtained on day +7. The results obtained in this peculiar case of neutropenia, and the kinetics of both fever and ANC, suggest the possible combination of neutrophil function enhancement and an anti-inflammatory effect of rhG-CSF.

Most patients with dengue experience mild disease, dengue fever (DF), while few develop the life-threatening diseases dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS). No laboratory tests predict DHF or DSS. We evaluated whether the serum chymase level can predict DHF or DSS in adult and pediatric patients and the influence of preexisting conditions (PECs) on chymase levels. Serum chymase levels were measured in patients presenting with undifferentiated fever to hospitals in Colombo District, Sri Lanka. The value of serum the chymase concentration and clinical signs and symptoms as predictors of DHF and/or DSS was evaluated by multivariate analysis. We assessed the influence of age, PECs, and day after fever onset on the robustness of the chymase level as a biomarker for DHF and/or DSS. An elevated chymase level in acute phase blood samples was highly indicative of later diagnosis of DHF or DSS for pediatric and adult patients with dengue. No recorded PECs prevented an increase in the chymase level during DHF. However, certain PECs (obesity and cardiac or lung-associated diseases) resulted in a concomitant increase in chymase levels among adult patients with DHF. These results show that patients with acute dengue who present with high levels of serum chymase consistently are at greater risk of DHF. The chymase level is a robust prognostic biomarker of severe dengue for adult and pediatric patients. © The Author 2017.

Previous studies having shown an appreciable level of yellow fever immunity to exist in northern Kenya, further epidemiological and serological surveys were carried out there in 1968 in an attempt to define more clearly the distribution of yellow fever and to locate possible vector and reservoir hosts of the disease; these surveys also provided information on a number of other arboviruses.Altogether 436 sera from 5 areas in northern Kenya were screened by haemagglutination-inhibition tests with 8 antigens, and 107 of these sera by neutralization tests for Group-B arboviruses. Small numbers of yellow-fever-immune adults were found in Ileret, Garissa, Loglogo and Mikona. At Marsabit high proportions of immune adults and children were found among the Burgi tribe. As the Burgi are permanent agricultural workers on Marsabit Mountain, an entomological investigation was made, over 15 000 mosquitos being collected. From these, 13 strains of Pongola virus, 1 strain of Semliki Forest virus and an unidentified virus were isolated, but no yellow fever strains. Aedes africanus and Aedes simpsoni were not found at Marsabit; small numbers of Aedes aegypti were collected biting man. The vector potential of other mosquitos collected (particularly Mansonia africana, which is present throughout the year) is discussed.

Scedosporium prolificans is a fungus that has demonstrated resistance against most currently available antifungal agents and which causes a rapidly disseminating and potentially fatal infection. A 68-year-old woman presented with a fever and consolidation in the lung field. Her symptoms and inflammatory reaction did not improve despite treatment with tazobactam/piperacillin, meropenem, and micafungin. Scedosporium prolificans was detected from the patient's bronchial lavage fluid, and we initiated treatment with voriconazole. Voriconazole was effective in shrinking the consolidation and suppressing the inflammatory reaction. The residual lesion was surgically resected because of the risk of systemic dissemination. The patient is currently alive without relapse or dissemination. PMID:28420849

2017-06-01

Cystic echinococcosis (CE) is a zoonotic disease; in places such as Turkey where livestock is common, it is an endemic health concern. The most commonly involved organ is the lungs in children. Pulmonary cysts can be asymptomatic; in some cases, they may rupture and become symptomatic. Ruptured lung hydatid cysts may often be confused with tuberculosis (Tbc) radiologically and clinically. . In this report, we present an 8-year-old female patient admitted with cough, fever, and sputum persisting since 2 weeks; her chest radiography and computed tomography (CT) findings initially indicated Tbc, but the follow-up surgery led to a diagnosis of ruptured lung CE. We want to emphasize that in children belonging to places where livestock is common, if respiratory symptoms are observed, CE and tuberculosis must be considered in the differential diagnosis, and the final diagnosis should be supported by other microbiological-serological tests.

A 56-year-old Caucasian lady presented with a short history of pleuritic chest pain on the background of a 2-month history of fever, chills, 10-kg weight loss and cough with brown sputum after a laparoscopic cholecystectomy. She had persistent eosinophilia and was diagnosed with a lung abscess as seen on chest x-ray. She did not respond to standard intravenous broad spectrum antibacterial medication and her chest CT scan showed a moderate pleural collection in continuity with the abscess. She also underwent bronchoscopy, the microscopy of the bronchial washings revealing eggs of the trematode Fasciola. The bacterial and fungal cultures of the washings were sterile. She had visited Turkey in the previous year but did not remember consuming any watercress or aquatic plants. She was successfully treated with two doses of the antiparasitic agent triclabendazole. Ectopic Fasciola can be a rare cause of a lung abscess.

Tiger's Milk mushroom is a tropical polypore genus that can be found in the tropical part of the world in Australia, Papua New Guinea, Philippines, Indonesia, Malaysia, Sri Lanka and Vanuatu. In Malaysia, Lignosus rhinocerus is the most sought after medicinal mushroom by Semai aborigine upon request by local herbalist. This priced mushroom has been used traditionally to treat various diseases such as asthma, breast cancer, cough, fever and food poisoning. Current results indicated polysaccharide from sclerotia of indigenous L. rhinocerus extracted through hot water is able to inhibit up to 45% growth of human lung carcinoma. Inhibition is achieved when concentration of polysaccharide are in the range of 4-8 μg/ml. Present preliminary study suggests beta-glucan-rich polysaccharide from sclerotia of indigenous L. rhinocerus has anti-proliferation activity on human lung carcinoma (A549).

Lung cancer is one of the most common types of malignancies worldwide. The majority of patients are diagnosed with an incurable advanced/metastatic stage disease. Palliative treatment approaches improve the survival and the quality of life of these patients. Lung cancer is subdivided according to histology and molecular biology. The most important classification separates small cell from non-small cell lung cancer. In the subgroup of non-small cell lung cancer novel treatment approaches coming along with an improved prognosis have been established during the last decade. The current manuscript provides an overview on current treatment options for metastatic lung cancer. Furthermore, an outlook on promising future treatment options is provided.

Background Relapsing fever is the most frequent bacterial disease in Africa. Four main vector / pathogen complexes are classically recognized, with the louse Pediculus humanus acting as vector for B. recurrentis and the soft ticks Ornithodoros sonrai, O. erraticus and O. moubata acting as vectors for Borrelia crocidurae, B. hispanica and B. duttonii, respectively. Our aim was to investigate the epidemiology of the disease in West, North and Central Africa. Methods And Findings From 2002 to 2012, we conducted field surveys in 17 African countries and in Spain. We investigated the occurrence of Ornithodoros ticks in rodent burrows in 282 study sites. We collected 1,629 small mammals that may act as reservoir for Borrelia infections. Using molecular methods we studied genetic diversity among Ornithodoros ticks and Borrelia infections in ticks and small mammals. Of 9,870 burrows investigated, 1,196 (12.1%) were inhabited by Ornithodoros ticks. In West Africa, the southern and eastern limits of the vectors and Borrelia infections in ticks and small mammals were 13°N and 01°E, respectively. Molecular studies revealed the occurrence of nine different Ornithodoros species, including five species new for science, with six of them harboring Borrelia infections. Only B. crocidurae was found in West Africa and three Borrelia species were identified in North Africa: B. crocidurae, B. hispanica, and B. merionesi. Conclusions Borrelia Spirochetes responsible for relapsing fever in humans are highly prevalent both in Ornithodoros ticks and small mammals in North and West Africa but Ornithodoros ticks seem absent south of 13°N and small mammals are not infected in these regions. The number of Ornithodoros species acting as vector of relapsing fever is much higher than previously known. PMID:24223812

In recent years the greatest progress in our understanding of pneumoconioses, other than those produced by asbestos, silica, and coal, has been in the arena of metal-induced parenchymal lung disorders. Inhalation of metal dusts and fumes can induce a wide range of lung pathology, including airways disorders, cancer, and parenchymal diseases. The emphasis of this update is on parenchymal diseases caused by metal inhalation, including granulomatous disease, giant cell interstitial pneumonitis, chemical pneumonitis, and interstitial fibrosis, among others. The clinical characteristics, epidemiology, and pathogenesis of disorders arising from exposure to aluminum, beryllium, cadmium, cobalt, copper, iron, mercury, and nickel are presented in detail. Metal fume fever, an inhalation fever syndrome attributed to exposure to a number of metals, is also discussed. Advances in our knowledge of antigen-specific immunologic reactions in the lung are particularly evident in disorders secondary to beryllium and nickel exposure, where immunologic mechanisms have been well characterized. For example, current evidence suggests that beryllium acts as an antigen, or hapten, and is presented by antigen-presenting cells to CD4+ T cells, which possess specific surface antigen receptors. Other metals such as cadmium and mercury induce nonspecific damage, probably by initiating production of reactive oxygen species. Additionally, genetic susceptibility markers associated with increased risk have been identified in some metal-related diseases such as chronic beryllium disease and hard metal disease. Future research needs include development of biologic markers of metal-induced immunologic disease, detailed characterization of human exposure, examination of gene alleles that might confer risk, and association of exposure data with that of genetic susceptibility.

The clinical and bacteriological findings in two cows the udders of which became infected under natural conditions with hemolytic streptococci of the scarlet fever type are discussed. One of the cows was found in a herd supplying raw milk to a small town where a milkborne outbreak of scarlet fever had occurred a short time before. When small numbers of the streptococcus obtained from this case were injected into the udder of a normal cow severe mastitis accompanied by a well marked general reaction resulted. Evidence leads to the conclusion that a severe attack of mastitis due to this organism in one quarter does not sufficiently immunize the other quarters to protect them completely since the streptococcus can be readily implanted in them. The secondary infections were much milder than the original process. PMID:19869456

Cancer patients often present altered serum lipid profile including changes of HDL cholesterol level. The aim of our work was to evaluate serum level of HDL cholesterol in patients with squamous cell and small cell lung cancer and its dependence on histological type and clinical stage of lung cancer. Fasting serum level of HDL cholesterol was analysed in 135 patients with newly diagnosed lung cancer and compared to a control group of healthy men. All lung cancer patients, as well as subgroups of squamous cell and small cell lung cancer had statistically significantly lower HDL cholesterol concentration than controls. There were no statistically significant differences of HDL cholesterol level between the histological types or between clinical stages of each histological type of lung cancer.

Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne viral disease presenting with flu-like symptoms, fever, hemorrhage and petechia. The virus (CCHFV) is a member of the Nairovirus genera of Bunyaviridae family and can be transmitted to humans by Hyalomma tick-bite, by exposure to infected blood and fomites of patient with CCHF or contact with animal tissue in viremic phase. In this study we present two cases with CCHF but without history of tick bite or exposure to infected fomites, even not coming from endemic areas. The first case was a 67 years old male patient presented with fever, fatique and shortness of breath. Physical examination revealed rales in right lower segments of lung. Laboratory findings showed elevation of liver enzymes with thrombocytopenia and prolonged prothrombin time. Serological markers for viral hepatitis, cytomegalovirus (CMV) and Epstein-Barr virus (EBV) were negative. The patient was found to be IgM and RNA positive for CCHFV by ELISA and polymerase chain reaction (PCR) methods, respectively. His history indicated a contact with livestock. The second patient was a 60 years old male dealing with husbandry. He had fever, fatique and myalgia. Physical examination revealed petechial rash on legs. Laboratory findings showed elevated liver enzymes, prolonged phrothrombin time and thrombocytopenia. Viral hepatitis markers, CMV-IgM and EBV-IgM were found negative. He was also found to be IgM and RNA positive for CCHFV in the reference laboratory. In conclusion, CCHF should be considered in the differential diagnosis of patients who contact with livestock and present with fever, fatigue, rash, elevated liver enzymes, thrombocytopenia and prolonged prothrombin time eventhough they do not reside in endemic areas for CCHF.

We report the case of a 19-year-old surfer, returning from Central America, who presented with chronic cough. The X-ray and full blood count, which had been performed in Costa Rica, were without pathology; laboratory parameters showed slightly increased C-reactive protein (59 mg/l). Malaria was excluded by thick smear. Immune serological tests for typhus, paratyphus, brucellosis, rickettsioses, leptospirosis and dengue fever were negative. An ambulant antimicrobial treatment was without any clinical effect. A computer tomography of the thorax showed a solid lesion (30 × 20 mm, middle lobe of the right lung). The patient rejected a bronchoscopic examination. He decided to be treated after his return to Austria. Here, we could substantiate a pulmonal histoplasmosis by a positive immune diffusion test. The patient was successfully treated with itraconazole.

The Pathogenesis of Rift Valley Fever

PubMed Central

Ikegami, Tetsuro; Makino, Shinji

2011-01-01

Rift Valley fever (RVF) is an emerging zoonotic disease distributed in sub-Saharan African countries and the Arabian Peninsula. The disease is caused by the Rift Valley fever virus (RVFV) of the family Bunyaviridae and the genus Phlebovirus. The virus is transmitted by mosquitoes, and virus replication in domestic ruminant results in high rates of mortality and abortion. RVFV infection in humans usually causes a self-limiting, acute and febrile illness; however, a small number of cases progress to neurological disorders, partial or complete blindness, hemorrhagic fever, or thrombosis. This review describes the pathology of RVF in human patients and several animal models, and summarizes the role of viral virulence factors and host factors that affect RVFV pathogenesis.

Despite extensive studies, the genetic and epigenetic mechanisms that mediate initiation and progression of lung cancers have not been fully elucidated. Previously, we have demonstrated that via complementary mechanisms, including DNA methylation, polycomb repressive complexes, and noncoding RNAs, cigarette smoke induces stem-like phenotypes that coincide with progression to malignancy in normal respiratory epithelia as well as enhanced growth and metastatic potential of lung cancer cells. To further investigate epigenetic mechanisms contributing to stemness/pluripotency in lung cancers and potentially identify novel therapeutic targets in these malignancies, induced pluripotent stem cells were generated from normal human small airway epithelial cells. Lung induced pluripotent stem cells were generated by lentiviral transduction of small airway epithelial cells of OSKM (Yamanaka) factors (octamer-binding transcription factor 4 [Oct4], sex-determining region Y box 2 [SOX2], Kruppel-like factor 4 [KLF4], and MYC proto-oncogene, bHLH transcription factor [MYC]). Western blot, real-time polymerase chain reaction, and chromatin immunoprecipitation sequencing analysis were performed. The lung induced pluripotent stem cells exhibited hallmarks of pluripotency, including morphology, surface antigen and stem cell gene expression, in vitro proliferation, and teratoma formation. In addition, lung induced pluripotent stem cells exhibited no chromosomal aberrations, complete silencing of reprogramming transgenes, genomic hypermethylation, upregulation of genes encoding components of polycomb repressive complex 2, hypermethylation of stem cell polycomb targets, and modulation of more than 15,000 other genes relative to parental small airway epithelial cells. Additional sex combs like-3 (ASXL3), encoding a polycomb repressive complex 2-associated protein not previously described in reprogrammed cells, was markedly upregulated in lung induced pluripotent stem cell as well as human small cell lung cancer lines and specimens. Overexpression of the additional sex combs like-3 gene correlated with increased genomic copy number in small cell lung cancer lines. Knock-down of the additional sex combs like-3 gene inhibited proliferation, clonogenicity, and teratoma formation by lung induced pluripotent stem cells and significantly diminished in vitro clonogenicity and growth of small cell lung cancer cells in vivo. Collectively, these studies highlight the potential utility of this lung induced pluripotent stem cell model for elucidating epigenetic mechanisms contributing to pulmonary carcinogenesis and suggest that additional sex combs like-3 is a novel target for small cell lung cancer therapy.

A 22-month-old male Spanish water dog was hospitalized after its physical examination revealed fever and movement difficulty. After 24h, the dog was found to have a high fever (39.5 °C) and was treated empirically with doxycycline/ciprofloxacin. At 48 h, after submission the fever rose to 41 °C and the animal presented with a stiff neck and dehydration. Peripheral blood and cerebrospinal fluid (CSF) were sampled and trophozoites with an Acanthamoeba-like morphology were observed in the CSF. PCR specific for Acanthamoeba, Naegleria fowleri and Balamuthia mandrillaris were performed and the CSF sample found positive for Acanthamoeba. Lungs, kidney, liver and spleen samples were collected post mortem. All collected organ samples were positive for Acanthamoeba by PCR, thus confirming a multisystemic infection. Water samples taken at a suspected site of infection yielded an almost identical PCR fragment to those of the clinical samples, indicating that this was probably where the infection originated. This is the first report of a fatal case of Acanthamoeba disseminated infection in a dog in Spain. Copyright © 2014 Elsevier B.V. All rights reserved.

Spontaneous excavation of primary lung cancer is common; however cavitation of metastatic lung lesions is rare and usually confused with benign lesions. In Moroccan context tuberculosis is the first suspected diagnosis of lung excavations. We report a rare case of cavitary lung metastasis of a uterine cervix cancer, treated initially as tuberculosis. A 40-year old non-smoking woman with a known history of squamous cell carcinoma of the uterine cervix since August 2005; presented on September 2008 with right chest pain without fever, hemoptysis or weight loss. CT scan showed a thin walled cavity. Empirical Antibiotic therapy was conducted 15 days with poor outcome. Then antibacillary treatment was started with no proof of mycobacterial infection. A month later, the patient presented with gynecological bleeding and a pneumothorax. Bronchoscopy with transbronchial biopsy of the cavitary mass was performed. Pathology demonstrated a metastatic squamous cell carcinoma. Pelvic examination and MRI showed a subsequent local cervix recurrence. Patient underwent 3 courses of systemic chemotherapy. She died on June 2009 due to progressive disease. Even cavitary lung metastases are rare and benign differential diagnosis are more common, clinician should be careful in neoplastic context and investigation should be done to eliminate a recurrence.

A 68-year-old man, complaining of fever and puriform sputum, was referred to our hospital. A giant abscess was detected in the upper lobe of the right lung. Percutaneous drainage of a lung abscess was carried out. When the pus collected was cultured, Candida was 1+ and Escherichia coli was 2+. Later, it became difficult to control the abscess by drainage, and cavernostomy was selected. The contents of the abscess cavity were removed, and the cavity was opened, followed by exchange of gauze every day. For 14 months after cavernostomy, once-weekly gauze exchange was continued at the outpatient clinic to clean the abscess cavity. Finally, the abscess was filled with a free greater omentum flap, accompanied by microvascular anastomosis. In this way, the intractable lung abscess was successfully cured. Conventionally, surgical treatment, particularly cavernostomy, has been applied only to limited cases when dealing with a lung abscess. Our experience with the present case suggests that surgical treatment, including cavernostomy as one option, should also be considered when dealing with lung abscesses resisting medical treatment and causing compromised respiratory function. To enable maximum utilization of the greater omental flap, which is available in only a limited amount, it seems useful to prepare and graft a free omental flap making use of microvascular surgery.

1. It has been possible to introduce yellow fever virus into the small Brazilian monkeys, Callithrix albicollis and Leontocebus ursulus, by the bites of infected mosquitoes and to carry the virus through a series of four passages in each species and back to rhesus monkeys by the bites of Stegomyia mosquitoes fed on the last marmoset of each series. 2. Five specimens of L. ursulus were used. Four developed fever, and all died during the experiments. At least two showed liver necroses comparable to those found in human beings and rhesus monkeys that died of yellow fever. 3. Twenty specimens of C. albicollis were used. Very few showed a temperature reaction following the introduction of virus. Of those that died, none had lesions typical of yellow fever as seen in certain other species of monkeys and in humans. 4. The convalescent serum from each of five C. albicollis protected a rhesus monkey against yellow fever virus, but the serum from a normal marmoset of the same species was found to be non-protective.

The impact of environmental change on transmission patterns of waterborne enteric diseases is a major public health concern. This study concerns the burden and spatial nature of enteric fever, attributable to Salmonella Typhi infection in the Central Division, Republic of Fiji at a sub-catchment scale over 30-months (2013-2015). Quantitative spatial analysis suggested relationships between environmental conditions of sub-catchments and incidence and recurrence of typhoid fever. Average incidence per inhabited sub-catchment for the Central Division was high at 205.9/100,000, with cases recurring in each calendar year in 26% of sub-catchments. Although the numbers of cases were highest within dense, urban coastal sub-catchments, the incidence was highest in low-density mountainous rural areas. Significant environmental determinants at this scale suggest increased risk of exposure where sediment yields increase following runoff. The study suggests that populations living on large systems that broaden into meandering mid-reaches and floodplains with alluvial deposition are at a greater risk compared to small populations living near small, erosional, high-energy headwaters and small streams unconnected to large hydrological networks. This study suggests that anthropogenic alteration of land cover and hydrology (particularly via fragmentation of riparian forest and connectivity between road and river networks) facilitates increased transmission of typhoid fever and that environmental transmission of typhoid fever is important in Fiji.

Only a few pathologic reports exist describing adult onset Still's disease (AOSD) with pulmonary involvement. We report this very rare case of AOSD complicated with cryptogenic organizing pneumonia (COP). A 32-year-old woman was referred with high spiking fever, salmon-pink rash in her arms and legs, and polyarthralgia. The laboratory data showed marked increases in white blood cell count, an erythrocyte sedimentation rate, and C reactive protein, ferritin, and liver dysfunction. All cultures remained negative, as were autoantibodies and rheumatoid factor. The patient was strongly suspected of AOSD according to specific diagnostic criteria. However, chest X ray disclosed an infiltrative shadow accompanied by air bronchogram in the upper lobe of the right lung and therapy with antibiotics was initiated. As the patient did not respond to antibiotics and a remittent fever of over 38°C, a flexible bronchoscopy was performed. Organizing pneumonia was diagnosed by transbronchial lung biopsy (TBLB) histology and radiologically, and the lesions were thought to be due to pulmonary involvement of AOSD. Therefore, she was diagnosed with AOSD complicated with COP. Oral treatment with prednisolone (30 mg/day) resulted in rapid disappearance of the infiltrative shadow. Symptoms and markers of inflammation also improved. Clinicians should be aware that COP can be a complication of AOSD.

Recombinant Swinepox Virus Expressing Glycoprotein E2 of Classical Swine Fever Virus Confers Complete Protection in Pigs upon Viral Challenge.

2017-01-01

Classical swine fever (CSF) is a highly contagious and serious viral disease that affects the pig industry worldwide. The glycoprotein E2 of the classical swine fever virus (CSFV) can induce neutralizing antibodies, and it is widely used for novel vaccine development. To explore the development of a vaccine against CSFV infections, the gene of glycoprotein E2 was inserted into the swinepox virus (SPV) genome by homologous recombination. The culture titers of rSPV-E2 remained at about 4.3 × 10 6 TCID 50 for more than 60 passages in PK15 and swine testis cell lines. The rSPV-E2 could not be replicated in Vero, MDBK or other non-porcine cell lines. After two to three passages, the SPV specific gene of rSPV-E2 could not been detected in the non-porcine cell culture. To evaluate the immunogenicity of rSPV-E2, 20 CSFV seronegative minipigs were immunized with rSPV-E2, a commercial C-strain vaccine, wild-type SPV (wtSPV; negative control), or PBS (a no-challenge control). After challenge with CSFV, pigs in the rSPV-E2-immunized group showed significantly shorter fever duration compared with the wtSPV-treated group ( P  < 0.05). E2-specific antibodies in the rSPV-E2-immunized group increased dramatically after vaccination and increased continuously over time. CSFV genomic copies in the serum of rSPV-E2-immunized pigs were significantly less compared with the wtSPV-treated group at all time points after challenge ( P  < 0.01). Significant reduction in gross lung lesion scores, histopathological liver, spleen, lung, and kidney lesion scores were noted in the rSPV-E2-immunized group compared with the wtSPV-treated group ( P  < 0.01). The results suggested that the recombinant rSPV-E2 provided pigs with significant protection from CSFV infections; thus, rSPV-E2 offers proof of principle for the development of a vaccine for the prevention of CSFV infections in pigs.

Rift Valley fever (RVF) is a zoonotic disease, which caused several epidemics in humans in many countries of Africa. Using an inhibition enzyme-linked immunosorbent assay (ELISA), real-time reverse transcription PCR, and nested one-step reverse transcription PCR, we conducted a cross-sectional study in populations of sheep and goats from the Mongo County in 2014 to determine the circulation of the Rift Valley fever virus (RVFV) in small ruminants from this area. From a total of 201 small ruminants (95 sheep and 106 goats), the overall IgG seroprevalence against the RVFV was 6.47% (13/201). No RVFV RNA was detected in the animal plasmas. Logistic regression analysis showed that age, species, sex, and locality were not the significant risk factors. The findings of this study highlight the risk of RVF for domestic ruminants bred in this region and for the human rural population living in contact with these animals and they emphasize the need to develop adequate control measures to limit this threat.

Endemic to the southwestern parts of the United States, coccidioidomycosis, also known as "Valley Fever," is a common fungal infection that primarily affects the lungs in both acute and chronic forms. Disseminated coccidioidomycosis is the most severe but very uncommon and usually occurs in immunocompromised individuals. It can affect the central nervous system, bones, joints, skin, and, very rarely, the abdomen. This is the first case report of a patient with coccidioidal dissemination to the peritoneum presenting as eosinophilic ascites (EA). A 27-year-old male presented with acute abdominal pain and distention from ascites. He had eosinophilia of 11.1% with negative testing for stool studies, HIV, and tuberculosis infection. Ascitic fluid exam was remarkable for low serum-ascites albumin gradient (SAAG), PMN count >250/mm(3), and eosinophils of 62%. Abdominal imaging showed thickened small bowel and endoscopic testing negative for gastric and small bowel biopsies. He was treated empirically for spontaneous bacterial peritonitis, but no definitive diagnosis could be made until coccidioidal serology returned positive. We noted complete resolution of symptoms with oral fluconazole during outpatient follow-up. Disseminated coccidioidomycosis can present in an atypical fashion and may manifest as peritonitis with low SAAG EA. The finding of EA in an endemic area should raise the suspicion of coccidioidal dissemination.

The patient was a 48-year-old woman and current smoker. In May 2007, she moved to a new residence. In the middle of the following month, she developed acute respiratory distress and a fever (38 degrees C) after running her air conditioner continuously throughout the night. The chest X-ray film showed diffuse infiltrative shadows in the middle and lower lung fields. After hospital admission, her oxygenation improved without treatment and the infiltrates improved over the clinical course. As a consequence, we suspected hypersensitivity pneumonitis. The bronchoalveolar lavage showed predominant lymphocytes of 72.6%, with a low CD 4/8 ratio of 0.2. Transbronchial lung biopsy findings corresponded to acute hypersensitivity pneumonitis. The results of the environmental challenge test were positive only when her air conditioner was on, resulting, in a diagnosis of air-conditioner lung. Several microorganisms were detected in an environmental sample, but 20 kinds of serum precipitating antibodies were negative on a thorough screening, so no responsible antigen could be identified. The patient's symptoms did not recur after her air conditioner was replaced.

Important roles played by invariant natural killer T (iNKT) cells in asthma pathogenesis have been demonstrated. We identified functional iNKT cells and CD1d molecules in pig lungs. Pig iNKT cells cultured in the presence of α-GalCer proliferated and secreted Th1 and Th2 cytokines. Like in other animal models, direct activation of pig lung iNKT cells using α-GalCer resulted in acute airway hyperreactivity (AHR). Clinically, acute AHR-induced pigs had increased respiratory rate, enhanced mucus secretion in the airways, fever, etc. In addition, we observed petechial hemorrhages, infiltration of CD4+ cells, and increased Th2 cytokines in AHR-induced pig lungs. Ex vivo proliferated iNKT cells of asthma induced pigs in the presence of C-glycoside analogs of α-GalCer had predominant Th2 phenotype and secreted more of Th2 cytokine, IL-4. Thus, baby pigs may serve as a useful animal model to study iNKT cell-mediated AHR caused by various environmental and microbial CD1d-specific glycolipid antigens. PMID:21042929

EXPERIMENTAL STUDIES ON YELLOW FEVER IN NORTHERN PERU.

Fourteen typical cases of yellow fever were studied in northern Peru during an epidemic occurring in 1920, nine in Payta in March and April, and five in Morropon and Piura in April and May. The method of investigation was similar to that previously employed, but as the laboratory facilities were very meager certain changes were required. Although in Payta the work was handicapped by the lack of electric light, the scarcity of water and animal food, the unsuitability of the guinea pigs for inoculation, and the changes in culture media due to age, the results obtained under these adverse conditions were by no means negative. While in no instance was there a typical infection produced in animals, either by direct inoculation of blood or with culture materials, yet certain guinea pigs in each series showed temporary febrile reactions or definite hemorrhagic lesions of the lungs indicative of a mild leptospira infection. Direct search for Leptospira icteroides in the blood of patients or in culture materials was not made because the dark-field microscope could not be used. Subsequently, at Piura, the laboratory facilities were vastly, improved, the use of the dark-field microscope was made possible by means of a storage battery, and a fresh stock of young healthy guinea pigs was received from New York, and fresh rabbit serum obtained in Piura. In the study of the materials obtained from five cases of yellow fever in Morropon all these added facilities were taken advantage of, with the result that the outcome was positive and convincing. Cultures from the five cases were examined after 11, 12, and 13 days, and in those from three cases living leptospiras were found. By inoculation into suitable guinea pigs of culture material from these five cases, irrespective of whether or not leptospiras were detected under the dark-field microscope, a typical Leptospira icteroides infection was produced from four of the five cases. In one of these no leptospira had been detected in the culture tubes. Thus one case only yielded negative results, in that no leptospiras were found under the dark-field microscope and the animal inoculation was negative. The leptospira was demonstrated in the blood or organ emulsions of the infected guinea pigs, and further transmission of each strain to other guinea pigs was obtained and pure cultures were secured. A few points of practical significance appeared in the course of the present investigation. One is the importance of using fresh rabbit serum for culture media. Old rabbit serum, whether in pure form or incorporated with agar, etc., which had been kept for several months in a tropical climate, proved to be unsatisfactory for obtaining a growth of Leptospira icteroides. A second point of interest is the variation in susceptibility of guinea pigs to infection with Leptospira icteroides. In two of four series of positive animal inoculations with the Morropon culture materials only one-half of the guinea pigs inoculated with given materials developed typical symptoms. The other half either suffered from a transient mild infection, as evidenced by a few hemorrhagic foci in the lungs, or escaped infection altogether. From these facts it is highly probable that the lung lesions and febrile reactions observed in certain guinea pigs inoculated with the Payta materials were due to a mild leptospira infection. In a comparative experiment the native guinea pigs procured in Payta were found to be more resistant to the leptospira infection than those recently brought from New York. In fact, only a small portion of the former succumbed to typical infection even when inoculated with a virulent strain of Leptospira icteroides obtained from the Morropon epidemic. In conclusion it may be stated that of fourteen cases of yellow fever studied in Peru, a typical leptospira infection, together with the demonstration of the organism in experimentally infected guinea pigs, was obtained in four, while in the majority of instances indications of a mild, non-fatal leptospira infection were observed. In a few cases only were the results entirely negative. The leptospira isolated from Morropon cases of yellow fever, which is morphologically and culturally identical with the Guayaquil and Merida strains of Leptospira icteroides, was also shown by immunity test to be indistinguishable from the Guayaquil organism.

Intratumoral lung abscess is a secondary lung abscess that is considered to be fatal. Therefore, surgical procedures, although high-risk, have sometimes been performed for intratumoral lung abscesses. However, no studies have examined the surgical outcomes of non-small cell lung cancer patients with intratumoral lung abscesses. The aim of this study was to investigate the surgical and survival outcomes of non-small cell lung cancer patients with intratumoral lung abscesses. Eleven consecutive non-small cell lung cancer patients with intratumoral lung abscesses, who had undergone pulmonary resection at our institution between January 2007 and December 2015, were retrospectively analysed. The post-operative prognoses were investigated and prognostic factors were evaluated. Ten of 11 patients were male and one patient was female. The median age was 64 (range, 52-80) years. Histopathologically, 4 patients had Stage IIA, 2 patients had Stage IIB, 2 patients had Stage IIIA, and 3 patients had Stage IV tumors. The median operative time was 346 min and the median amount of bleeding was 1327 mL. The post-operative morbidity and mortality rates were 63.6% and 0.0%, respectively. Recurrence of respiratory infections, including lung abscesses, was not observed in all patients. The median post-operative observation period was 16.1 (range, 1.3-114.5) months. The 5-year overall survival rate was 43.3%. No pre-operative, intra-operative, or post-operative prognostic factors were identified in the univariate analyses. Surgical procedures for advanced-stage non-small cell lung cancer patients with intratumoral lung abscesses, although high-risk, led to satisfactory post-operative mortality rates and acceptable prognoses.

Blood coagulation test results were collected prospectively in patients with previously untreated, advanced lung or colon cancer who entered into a clinical trial. In patients with colon cancer, reduced survival was associated (in univariate analysis) with higher values obtained at entry to the study for fibrinogen, fibrin(ogen) split products, antiplasmin, and fibrinopeptide A and accelerated euglobulin lysis times. In patients with non-small cell lung cancer, reduced survival was associated (in univariate analysis) with higher fibrinogen and fibrin(ogen) split products, platelet counts and activated partial thromboplastin times. In patients with small cell carcinoma of the lung, only higher activated partial thromboplastin times were associated (in univariate analysis) with reduced survival in patients with disseminated disease. In multivariate analysis, higher activated partial thromboplastin times were a significant independent predictor of survival for patients with non-small cell lung cancer limited to one hemithorax and with disseminated small cell carcinoma of the lung. Fibrin(ogen) split product levels were an independent predictor of survival for patients with disseminated non-small cell lung cancer as were both the fibrinogen and fibrinopeptide A levels for patients with disseminated colon cancer. These results suggest that certain tests of blood coagulation may be indicative of prognosis in lung and colon cancer. The heterogeneity of these results suggests that the mechanism(s), intensity, and pathophysiological significance of coagulation activation in cancer may differ between tumour types.

Lung cancer is one of the most common causes of cancer-related death in the world. The large number of lung cancer cases is non-small cell lung cancer (NSCLC), which approximately accounting for 75% of lung cancer. Over the past years, our comprehensive knowledge about the molecular biology of NSCLC has been rapidly enriching, which has promoted the discovery of driver genes in NSCLC and directed FDA-approved targeted therapies. Of course, the targeted therapies based on driver genes provide a more exact option for advanced non-small cell lung cancer, improving the survival rate of patients. Now, we will review the landscape of driver genes in NSCLC including the characteristics, detection methods, the application of target therapy and challenges. PMID:28915704

Small cell lung cancer is the most aggressive histologic subtype of lung cancer, with a strong predilection for metastasizing to brain early. However, the cellular and molecular basis is poorly known. Here, we provided evidence to reveal the role of annexin A1 in small cell lung cancer metastasis to brain. Firstly, the elevated annexin A1 serum levels in small cell lung cancer patients were associated with brain metastasis. The levels of annexin A1 were also upregulated in NCI-H446 cells, a small cell lung cancer cell line, upon migration into the mice brain. More interestingly, annexin A1 was secreted by NCI-H446 cells in a time-dependent manner when co-culturing with human brain microvascular endothelial cells, which was identified with the detections of annexin A1 in the co-cultured cellular supernatants by ELISA and western blot. Further results showed that blockage of annexin A1 in the co-cultured cellular supernatants using a neutralized antibody significantly inhibited NCI-H446 cells adhesion to brain endothelium and its transendothelial migration. Conversely, the addition of Ac2-26, an annexin A1 mimic peptide, enhanced these effects. Furthermore, knockdown of annexin A1 in NCI-H446 cells prevented its transendothelial migration in vitro and metastasis to mice brain in vivo. Our data showed that small cell lung cancer cell in brain microvasculature microenvironment could express much more annexin A1 and release it outside, which facilitated small cell lung cancer cell to gain malignant properties of entry into brain. These findings provided a potential target for the management of SCLC brain metastasis. Copyright © 2015 Elsevier Ltd. All rights reserved.

The Ki-67 antigen (Ki-67) is the most reliable immunohistochemical marker for evaluation of cell proliferation in non-small cell lung cancer. However, the mechanisms underlying the regulation of protein levels of Ki-67 in non-small cell lung cancer have remained elusive. In this study, we found that Ki-67 and ubiquitin-specific processing protease 7 (USP7) protein were highly expressed in the nucleus of non-small cell lung cancer cells. Furthermore, statistical analysis uncovered the existence of a strong correlation between Ki-67 and USP7 levels. We could also show that the protein levels of Ki-67 in non-small cell lung cancer cells significantly decreased after treatment with P22077, a selective chemical inhibitor of USP7, while the Ki-67 mRNA levels were unperturbed. Similar results were obtained by knocking down USP7 using short hairpin RNA (shRNA) in lung cancer cells. Interestingly, we noticed that ubiquitination levels of Ki-67 increased dramatically in USP7-silenced cells. The tests in vitro and vivo showed a significant delay in tumor cell growth upon knockdown of USP7. Additionally, drug sensitivity tests indicated that USP7-silenced A549 cells had enhanced sensitivity to paclitaxel and docetaxel, while there was no significant change in sensitivity toward carboplatin and cisplatin. Taken together, these data strongly suggest that the overexpression of USP7 might promote cell proliferation by deubiquitinating Ki-67 protein, thereby maintaining its high levels in the non-small cell lung cancer. Our study also hints potential for the development of deubiquitinase-based therapies, especially those targeting USP7 to improve the condition of patients diagnosed with non-small cell lung cancer.

We report a 33-year-old female with cutaneous involvement by Churg-Strauss syndrome confined to surgical scars that were obtained 13 years before. She presented to the emergency department with 2-day history of fever, night sweats, right-sided weakness, hoarseness and worsening asthma symptoms. She was found to have an eosinophilia and two sub-5-mm pulmonary nodules. The patient also reported that the scars on her right thumb, inner wrist and back had been swollen, red and painful for 2 days. Examination revealed tender, erythematous, well-healed edematous scars studded with small skin colored papules. She had no clinical findings that were classic for cutaneous vasculitis. A skin biopsy of a scar revealed perivascular and palisading granulomatous inflammation consisting of histiocytes and neutrophils with leukocytoclasia. Focal vascular injury was identified. Scattered tissue eosinophils were seen. Special stains were negative for infection. Thereafter, she was started on intravenous steroids, at which point the fever, pulmonary and cutaneous symptoms subsided. Although scar sarcoidosis is a well-described phenomenon, granulomatous inflammation and vasculitis seen in Churg-Strauss syndrome exclusively manifesting in well-healed surgical scars highlights the unique features seen in this case and draws attention to the concept of locus minoris resistentiae. This case also highlights how a skin biopsy in the setting of suspected systemic vasculitis can confirm the presence of vasculitis and/or granulomatous inflammation and obviate the need for more invasive, higher risk procedures such as lung biopsy.

Ectoparasites were sampled from small mammals collected in West Java, West Sumatra, North Sulawesi, and East Kalimantan, Indonesia, in 2007-2008 and were screened for evidence of infection from bacteria in the Rickettsaceae family. During eight trap nights at eight sites, 208 fleas were collected from 96 of 507 small mammals trapped from four orders (379 Rodentia; 123 Soricomorpha; two Carnivora; three Scandentia). Two species of fleas were collected: Xenopsylla cheopis (n = 204) and Nosopsyllus spp. (n = 4). Among the 208 fleas collected, 171 X. cheopis were removed from rats (Rattus spp.) and 33 X. cheopis from shrews (Suncus murinus). X. cheopis were pooled and tested for DNA from rickettsial agents Rickettsia typhi, Rickettsia felis, and spotted fever group rickettsiae. R. typhi, the agent of murine typhus, was detected in X. cheopis collected from small mammals in West Java and East Kalimantan. R. felis was detected in X. cheopis collected from small mammals in Manado, North Sulawesi. R. felis and spotted fever group rickettsiae were detected in a pool of X. cheopis collected from an animal in East Kalimantan. Sixteen percent of the X. cheopis pools were found positive for Rickettsia spp.; four (10.8%) R. typhi, one (2.7%) R. felis, and one (2.7%) codetection of R. felis and a spotted fever group rickettsia. These data suggest that rickettsial infections remain a threat to human health across Indonesia.

Varicella is a common, highly contagious viral infection of childhood. Varicella is a usually benign and self-limited disease, but it can be complicated by severe bacterial infections, especially in immunocompromised hosts. In this study, we describe a previously healthy 3-months-old infant who was admitted with high fever, cough, and respiratory distress, who had a history of varicella infection three weeks before, with exposure from her adolescent, unvaccinated sister. A lung abscess caused by Staphylococcus aureus complicating the varicella infection was discovered. The patient was aggressively treated with drainage of the abscess and intravenous antibiotics and had a good recovery. Copyright © 2016 King Saud Bin Abdulaziz University for Health Sciences.

Zika virus disease is an acute infectious disease caused by Zika virus transmitted through Aedes mosquitoes. To explore the therapeutic effect of integrated traditional Chinese and Western Medicine for Zika virus disease, the treatment process of the first imported case in China was reviewed. The first imported Zika virus disease in China was admitted to Ganxian People's Hospital in Jiangxi Province on February 6th, 2016, and the patient received isolation treatment for 9 days and cured later. The effect of antiviral treatments including Xiyanping injection was evaluated based on clinical diagnosis and treatment process of the patient. A 34-year old male patient was admitted with chief complaint of fever for 9 days, orbital pain and itching rash for 4 days on February 6th, 2016. (1) Epidemiological characteristics: the patient was bitted by mosquitoes during his business trip in Venezuela since January 1st, where Zika virus disease was spreading. On January 20th he had dizziness without fever, and the symptom disappeared after taking medicines without details. Paroxysmal dizziness, chills and mild fever without myalgia was experienced on January 28th. On February 3rd small red rash appeared in the neck, spreading to anterior part of chest, limbs and trunk, and the fever, fatigue, nausea was continued, and a new symptom of paroxysmal pain in back of ears and orbits appeared, during which he had not go to hospital. The symptoms relieved on February 4th. He returned to Ganxian County on February 5th, he had yellow stool 3 times with normal temperature, without abdominal pain, and red rash still appeared in the neck. He went to Ganxian People's Hospital on February 6th, 2016. (2) Clinical manifestation: the vital signs showed a temperature of 36.8?centigrade, a pulse rate of 80 bpm, a respiratory rate of 20 bpm, and a blood pressure of 110/70 mmHg (1 mmHg = 0.133 kPa). It was showed by physical examination that red rash appeared in the neck, and no superficial enlarged lymph nodes were found. Bilateral conjunctival congestion was obvious, physiological reflex existed and pathological reflex was not found. (3) Auxiliary lab test and examination: no abnormal finding were revealed throughout examination and laboratory tests, including routine blood test, liver function, renal function, serum myocardial enzyme, electrolyte, blood sugar, C-reactive protein (CRP), troponin I (TnI), and procalcitonin (PCT), except slight prolongation in activated partial thromboplastin time (APTT, 38.6 s) on February 6th; and slightly dense shadow in left lung in lung CT scan, considering inflammatory changes and slight emphysema (especially in the left lower lung) as well as bilateral renal calculus on February 8th. No significant abnormalities were found in electrocardiogram and B ultrasound test of liver, spleen, and pancreas. (4) Virus confirmation: Zika virus nucleic acid was positive reported by Jiangxi Province Center for Disease Control and Prevention (CDC) on February 7th and Chinese CDC on February 9th, respectively, though Dengue virus were negative reported by Ganzhou CDC on February 6th. Right after the first diagnosis, anyone who had been in close contact with the patient received medical monitoring. (5)Treatment process: on February 6th, symptomatic treatment was prescribed since admitted into the infectious isolation wards and daily intravenous drip of Xiyanping injection 250 mg was prescribed for antiviral therapy. On February 7th, the patient had no fever, with occasional chills, neck rash was disappeared, orbital pain relieved and bilateral conjunctival hyperemia range was paler and narrowed, and his condition improved. Ibuprofen was administered for defervesce 3 times a day when his temperature reached to 37.5?centigrade at 16:00. On February 8th, the patient had no fever, times of chills was significantly reduced, without myalgia and rash, orbital pain and conjunctival hyperemia further recovered. On February 9th, bilateral eyes slightly tingling, mild conjunctival congestion, no fever chills or other discomfort was found. The chloramphenicol eye drops was prescribed for relieving sting pain with conjunctival congestion twice a day as recombinant human interferon alpha eye drops was out of store. The patient was comfortable from February 11th to February 13th. Blood and urine test for Zika were reported negative by the Chinese CDC and Jiangxi Province CDC. Because all the discharge criteria were satisfied, the patient was discharged on February 14th. At present, there is no specific effective drug to prevent and treat Zika virus disease effectually. After receiving symptomatic treatment and antiviral treatments including Xiyanping injection, the patient's symptoms were relieved. Zika virus nucleic acid in blood and urine was negative. The patient was discharged. Combination of traditional Chinese medicine and Western medicine maybe a good method to prevent and treat Zika virus disease.

Non-small cell lung cancer constitutes the most common type of lung cancer, accounting for 85-90% of lung cancer, and is a leading cause of cancer-related death. Despite the progress during the past years, poor prognosis remains a challenge and requires further research and development of novel antitumor treatment. Recently, the role of histone deacetylases in gene expression has emerged showing their regulation of the acetylation of histone proteins and other non-histone protein targets and their role in chromatin organization, while their inhibitors, the histone deacetylase inhibitors, have been proposed to have a potential therapeutic role in diverse malignancies, including non-small cell lung cancer. This review article focuses on the role of histone deacetylase inhibitors in the treatment of non-small cell lung cancer and the major molecular mechanisms underlying their antitumor activity recognized so far.

Two mutations of methylenetetrahydrofolate reductase (MTHFR) gene (C677T and A1298C) may lead to a decreased activity of the enzyme. These mutations may change a risk of some cancers. We evaluated these two polymorphisms of MTHFR in patients with small cell lung cancer (SCLC) and non-small cell lung cancer (NCSCL). All lung cancer patients had statistically significantly higher percentage of MTHFR 677TT genotype in comparison with non-cancer controls. There were no statistically significant differences in the distribution of MTHFR 1298 genotypes. Neither of the polymorphisms presented any statistically significant differences between SCLC and NSCLC.

Murine Typhus

Rickettsia typhi: is an intracellular bacteria who causes murine typhus. His importance is reflected in the high frequency founding specific antibodies against Rickettsia typhi in several worldwide seroepidemiological studies, the seroprevalence ranging between 3-36%. Natural reservoirs of R. typhi are rats (some species belonging the Rattus Genus) and fleas (Xenopsylla cheopis) are his vector. This infection is associated with overcrowding, pollution and poor hygiene. Typically presents fever, headache, rash on trunk and extremities, in some cases may occur organ-specific complications, affecting liver, kidney, lung or brain. Initially the disease is very similar to other diseases, is very common to confuse the murine typhus with Dengue fever, therefore, ignorance of the disease is a factor related to complications or non-specific treatments for the resolution of this infection. This paper presents the most relevant information to consider about the rickettsiosis caused by Rickettsia typhi. PMID:24893060

THE PRESENCE OF ENDOGENOUS PYROGEN IN NORMAL RABBIT TISSUES.

PubMed

SNELL, E S; ATKINS, E

1965-06-01

Saline extracts of homogenized, uninfected, rabbit tissues produced febrile responses when injected intravenously into rabbits. Extracts of muscle, lung, and heart evoked fevers that were similar to those induced by leucocyte pyrogen; extracts of spleen, liver, and kidney caused more sustained fevers. The minimal pyrogenic dose appeared to be between 1.5 and 3 gm wet weight of tissue. Evidence is presented that neither Gram-negative bacterial endotoxin nor polymorphonuclear leucocytes (circulating or sequestered in the tissues) can be implicated as the source of pyrogen in tissue extracts. It seems likely, therefore, that a pyrogenic material of truly endogenous origin is widely distributed in tissues. Tissue pyrogen appears to be a large molecule which is relatively resistant to treatment with acid but not with alkali. Possible pathological roles for this endogenous agent (or agents) are briefly indicated.

Non–small cell lung cancer, as the most frequent type lung cancer, has lower survival rate of 5 years, despite improvements in surgery and chemotherapy. Previous studies showed immature colon carcinoma transcript 1 is closely related to tumorigenesis of human cancer cells. In the present study, we found immature colon carcinoma transcript 1 was overexpressed in lung cancer tissues using Oncomine database mining, and the biological effect of immature colon carcinoma transcript 1 was investigated in non–small cell lung cancer cell lines 95D and A549. Lentivirus-mediated RNA interference was used to knock down immature colon carcinoma transcript 1 expression in 95D and A549 cells in vitro, and the knockdown efficiency was determined using quantitative real-time polymerase chain reaction and Western blot assay. Knockdown of immature colon carcinoma transcript 1 significantly suppressed non–small cell lung cancer cell proliferation and colony formation ability confirmed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and colony formation assay. Flow cytometry was applied to measure cell cycle arrest, and the result showed the cell cycle arrested in G2/M phase in 95D cells and arrested in G0/G1 phase in A549 cells. Furthermore, we measured the levels of cell cycle–associated proteins by Western blot analysis and found immature colon carcinoma transcript 1–mediated cell proliferation inhibition appeared due to downregulation of cell cycle activator cyclin D1 and upregulation of cell cycle inhibitor p21. In addition, immature colon carcinoma transcript 1 silencing significantly induced non–small cell lung cancer cell apoptosis by annexin V/7-amino-actinomycin D double-staining assay. All our data suggest that immature colon carcinoma transcript 1 may play an important role for non–small cell lung cancer cell proliferation and could be a potential molecular target for diagnosing and treating human non–small cell lung cancer.

What is the prognostic significant of the histomorphology in the small cell carcinomas of the lung? After the WHO classification of the lung cancer (1981), several studies criticized the subdivision of the small cell carcinoma in three sub-types (oat-cell, intermediate cell and combined types). The role of histology in the prognostic predition has been devaluated. In order to verify the prognostic value of the morphology of the small cell types of lung cancer, we performed a multivariate analysis in 62 patients. The survival rate was analytically compared with the following parameters: nuclear maximum diameter, nuclear form, nuclear chromatism, chromatine distribution, presence of nucleolus, evidence of cytoplasm. The results showed that none of these parameters are able to express a prognostic value. According to the recent studies, we think that the small cell carcinoma of the lung is a neoplasia with a multiform histologic pattern. Differences observed in clinical management are not correlate with the morphology, but with other biological parameters still unknown.

It has been hypothesized that bombesin-like peptides produced by small cell lung carcinomas may sustain deregulated proliferation through an autocrine mechanism. The authors have shown that the neuropeptide bombesin leads to the activation of a protein-tyrosine kinase that phosphorylates a 115-kDa protein (p115) associated with the bombesin receptor complex in mouse Swiss 3T3 fibroblasts. They now report that phosphotyrosine antibodies recognize a 115-kDa protein, phosphorylated on tyrosine, in four human small cell lung carcinoma cell lines producing bombesin but not in a nonproducer variant line. p115 from detergent-treated small cell lung carcinoma cells binds to bombesin-Sepharose and can be phosphorylatedmore » on tyrosine in the presence of radiolabeled ATP and Mn{sup 2+}. As for the p115 immunoprecipitated from mouse fibroblast, the small cell lung carcinoma p115 can be phosphorylated in an immunocomplex kinase assay. However, the latter does not require the presence of exogenous bombesin for activity. Binding data, obtained by using radiolabeled ligand, suggest receptor occupancy in the cell lines producing bombesin. These observations are consistent with the hypothesis that proliferation in some human small cell lung carcinoma lines is under autocrine control, regulated through activation of bombesin receptors.« less

Compartmentalized, functional role of angiogenin during spotted fever group rickettsia-induced endothelial barrier dysfunction: evidence of possible mediation by host tRNA-derived small noncoding RNAs

PubMed Central

2013-01-01

Background Microvascular endothelial barrier dysfunction is the central enigma in spotted fever group (SFG) rickettsioses. Angiogenin (ANG) is one of the earliest identified angiogenic factors, of which some are relevant to the phosphorylation of VE-cadherins that serve as endothelial adherens proteins. Although exogenous ANG is known to translocate into the nucleus of growing endothelial cells (ECs) where it plays a functional role, nuclear ANG is not detected in quiescent ECs. Besides its nuclear role, ANG is thought to play a cytoplasmic role, owing to its RNase activity that cleaves tRNA to produce small RNAs. Recently, such tRNA-derived RNA fragments (tRFs) have been shown to be induced under stress conditions. All these observations raise an intriguing hypothesis about a novel cytoplasmic role of ANG, which is induced upon infection with Rickettsia and generates tRFs that may play roles in SFG rickettsioses. Methods C3H/HeN mice were infected intravenously with a sublethal dose of R. conorii. At days 1, 3, and 5 post infection (p.i.), liver, lung and brain were collected for immunofluorescence (IF) studies of R. conorii and angiogenin (ANG). Human umbilical vein endothelial cells (HUVECs) were infected with R. conorii for 24, 48, and 72 hrs before incubation with 1μg/ml recombinant human ANG (rANG) in normal medium for 2 hrs. HUVEC samples were subjected to IF, exogenous ANG translocation, endothelial permeability, and immunoprecipitation phosphorylation assays. To identify small non-coding RNAs (sncRNAs) upon rickettsial infection, RNAs from pulverized mouse lung tissues and HUVECs were subjected to library preparation and deep sequencing analysis using an Illumina 2000 instrument. Identified sncRNAs were confirmed by Northern hybridization, and their target mRNAs were predicted in silico using BLAST and RNA hybrid programs. Results In the present study, we have demonstrated endothelial up-regulation of ANG, co-localized with SFG rickettsial infection in vivo. We also have provided direct evidence that rickettsial infection sensitizes human ECs to the translocation of exogenous ANG in a compartmentalized pattern at different times post-infection. Typically, exogenous ANG translocates into the nucleus at 24 hrs and to the cytoplasm at 72 hrs post-infection. The ANG cytoplasmic translocation enhances phosphorylation and destabilization of VE-cadherin and attenuates endothelial barrier function. Of note, deep sequencing analysis detected tRFs, mostly derived from the 5'-halves of host tRNAs, that are induced by ANG. Northern hybridization validates the two most abundantly cloned tRFs derived from tRNA-ValGTG and tRNA-GlyGCC, in both mouse tissues and human cells. Bioinformatics analysis predicted that these tRFs may interact with transcripts associated with the endothelial barrier, the host cell inflammatory response, and autophagy. Conclusions Our data provide new insight into the role of compartmentalized ANG during SFG rickettsioses, and highlight its possible mediation through tRFs. PMID:23800282

Detection and visualization of lung tissue structures is impaired by predominance of air. However, by using synchrotron x-rays, refraction of x-rays at the interface of tissue and air can be utilized to generate contrast which may in turn enable quantification of lung optical properties. We utilized multiple image radiography, a variant of diffraction enhanced imaging, at the Canadian light source to quantify changes in unique x-ray optical properties of lungs, namely attenuation, refraction and ultra small-angle scatter (USAXS or width) contrast ratios as a function of lung orientation in free-breathing or respiratory-gated mice before and after intra-nasal bacterial endotoxin (lipopolysaccharide) instillation. The lung ultra small-angle scatter and attenuation contrast ratios were significantly higher 9 h post lipopolysaccharide instillation compared to saline treatment whereas the refraction contrast decreased in magnitude. In ventilated mice, end-expiratory pressures result in an increase in ultra small-angle scatter contrast ratio when compared to end-inspiratory pressures. There were no detectable changes in lung attenuation or refraction contrast ratio with change in lung pressure alone. In effect, multiple image radiography can be applied towards following optical properties of lung air-tissue barrier over time during pathologies such as acute lung injury.

Lung cancer is one of the most common cancers and is the leading cause of cancer death. We wish to identify peptide ligands for unique cell surface receptors of non-small lung cancer with the hope of developing these ligands as diagnostic and therapeutic agents. Using the method of 'one-bead one-peptide' combinatorial chemistry, a library of random cyclic octapeptides was synthesized on polystyrene beads. This library was used to screen for peptides that promoted attachment of lung adenocarcinoma cells employing a 'cell-growth-on-bead' assay. Consensus peptide sequences of cNGXGXXc were identified. These peptides promoted cell adhesion by targeting integrin alpha3beta1 over-expressed in non-small lung cancer cells. These peptide beads can be applied to capture cancer cells in malignant pleural fluid for purpose of diagnosis of lung cancer.

Neuroendocrine specific lung cancers comprise about 10% of non-small cell lung cancer (NSCLC) cases and all small cell lung cancer (SCLC) cases. Studies have previously shown that the transcription factor achaete-scute homolog 1 (ASCL1) is a cancer “lineage” factor required for the development and survival of SCLC, and is highly expressed in neuroendocrine-specific NSCLC (NE-NSCLC).

Purpose: To report on significant dose enhancement effects caused by magnetic fields aligned parallel to 6 MV photon beam radiotherapy of small lung tumors. Findings are applicable to future inline MRI-guided radiotherapy systems. Methods: A total of eight clinical lung tumor cases were recalculated using Monte Carlo methods, and external magnetic fields of 0.5, 1.0, and 3 T were included to observe the impact on dose to the planning target volume (PTV) and gross tumor volume (GTV). Three plans were 6 MV 3D-CRT plans while 6 were 6 MV IMRT. The GTV’s ranged from 0.8 to 16 cm{sup 3}, whilemore » the PTV’s ranged from 1 to 59 cm{sup 3}. In addition, the dose changes in a 30 cm diameter cylindrical water phantom were investigated for small beams. The central 20 cm of this phantom contained either water or lung density insert. Results: For single beams, an inline magnetic field of 1 T has a small impact in lung dose distributions by reducing the lateral scatter of secondary electrons, resulting in a small dose increase along the beam. Superposition of multiple small beams leads to significant dose enhancements. Clinically, this process occurs in the lung tissue typically surrounding the GTV, resulting in increases to the D{sub 98%} (PTV). Two isolated tumors with very small PTVs (3 and 6 cm{sup 3}) showed increases in D{sub 98%} of 23% and 22%. Larger PTVs of 13, 26, and 59 cm{sup 3} had increases of 9%, 6%, and 4%, describing a natural fall-off in enhancement with increasing PTV size. However, three PTVs bounded to the lung wall showed no significant increase, due to lack of dose enhancement in the denser PTV volume. In general, at 0.5 T, the GTV mean dose enhancement is around 60% lower than that at 1 T, while at 3 T, it is 5%–60% higher than 1 T. Conclusions: Monte Carlo methods have described significant and predictable dose enhancement effects in small lung tumor plans for 6 MV radiotherapy when an external inline magnetic field is included. Results of this study indicate that future clinical inline MRI-guided radiotherapy systems will be able to deliver a dosimetrically superior treatment to small (PTV < 15 cm{sup 3}), isolated lung tumors over non-MRI-Linac systems. This increased efficacy coincides with the reimbursement in the United States of lung CT screening and the likely rapid growth in the number of patients with small lung tumors to be treated with radiotherapy.« less

Lung cancer ranks as the top cancer worldwide in terms of incidence and constitutes a major health problem. About 90% of lung cancer cases are diagnosed at advance stage where treatment is not available. Despite evidence that lung cancer screening improves survival, guidelines for lung cancer screening are still a subject for debate. In Saudi Arabia, only 14% of lung cancers are diagnosed at early stage and researches on survival and its predictors are lacking. This overview analysis was conducted on predictors of lung cancer mortality according to the two major cancer types, small-cell lung cancers (SCLCs) and non-small cell lung cancers (NSCLCs) in Saudi Arabia. A secondary data analysis was performed on small-cell lung cancers (SCLCs) and Non-small cell lung cancers (NSCLCs) registered in the Saudi Cancer Registry (SCR) for the period 2009-2013 to estimate predictors of mortality for both lung cancer types. A total of 404 cases (197 SCLC and 207 NSCLC) were included in the analysis, all Saudi nationals. A total of 213 (52.75%) deaths occurred among lung cancer patients, 108 (54.82%) among SCLCs and 105 (50.72%) among NCSLCs. Three quarter of patients are diagnosis with advance stage for both SCLC & NSCLC. Univariate analysis revealed higher mean age at diagnosis in dead patients compared to alive patients for SCLCs (p=0.04); but not NSCLCs, a lower mortality for NSCLCs diagnosed in 2013 (p=0.025) and a significant difference in stage of tumor (p=0.006) and (p=0.035) for both SCLC and NSCLC respectively. In multiple logistic regression, stage of tumor was a strong predictor of mortality, where distant metastasis increased morality by 6-fold (OR=5.87, 95% CI: 2.01 - 17.19) in SCLC and by 3-fold (OR=3.29, 95% CI: 1.22 - 8.85) in NSCLC, compared to localized tumors. Those with NSCLC who were diagnosed in 2013 were less likely to die by 64% compared to NSCLC diagnosed in 2009 (OR=0.36, 95% CI: 0.14 - 0.93). Age, sex, topography and laterality were not associated with mortality for both types of lung cancer. We observed that the stage of the tumor is the strongest predictor of mortality for both SCLCs and NSCLs. This confirms the impact of diagnostic stage on survival. However, establishing Saudi-specific lung cancer screening guidelines will require further research on the benefits and harms of screening modalities in the Saudi population.

The synchronous occurrence of lung cancer in patients with gastric neoplasms is relatively uncommon, especially the cases of synchronous coexistence of small cell lung carcinoma and diffuse large B-cell lymphoma of the stomach. We encountered a case of synchronous primary small cell lung carcinoma and diffuse large B-cell lymphoma of the stomach. A 63-year-old patient with a 7.5 × 5.09 cm mass in the superior lobe of the right lung diagnosed with small cell lung cancer and synchronous diffuse large B-cell lymphoma of the stomach. The diseases were diagnosed by the pathological biopsy and immunohistochemical methods. As the patient received CHOP chemotherapy, pulmonary function deterioraed. Etoposide was added to the chemotherapy. However, after the first treatment, chest computed tomography showed that the mass in the superior lobe of the right lung had increased to 8.5 × 5.2 cm. This report draws attention to the fact that the treatment of synchronous tumors is a challenge. Copyright © 2017 The Authors. Published by Wolters Kluwer Health, Inc. All rights reserved.

Abnormal expression of microRNAs has been reported to regulate gene expression and cancer cell growth, invasion, and migration. Recently, upregulation of hsa-miR-1285 was demonstrated in bronchoalveolar lavage fluid samples from patients with lung cancer and downregulation in plasma level of stage-I lung cancer patients. However, the function and the underlying mechanism of miR-1285 in non-small-cell lung carcinoma have not been elucidated. In this study, we found that miR-1285-5p, the mature form of miR-1285, was significantly upregulated in human non-small-cell lung carcinoma cell lines A549 and SK-MES-1. Additionally, cells transfected with the miR-1285-5p inhibitor LV-anti-miR-1285-5p demonstrated significantly inhibited proliferation and invasion and depressed migration. Further analysis demonstrated that the miR-1285-5p precursor LV-miR-1285-5p attenuated the expression of Smad4 and cadherin-1 (CDH1) but that LV-anti-miR-1285-5p showed opposite results. A luciferase reporter assay confirmed that miR-1285-5p targeted Smad4 and CDH1. Mechanism analyses revealed that silence of Smad4 and CDH1 significantly attenuated the inhibitory effects of LV-anti-miR-1285-5p on non-small-cell lung carcinoma growth and invasion. Taken together, our data suggest that miR-1285-5p functions as a tumor promoter in the development of non-small-cell lung carcinoma by targeting Smad4 and CDH1, indicating a novel therapeutic strategy for non-small-cell lung carcinoma patients.

Solid neoplasms can be directly responsible for organ failures at the time of diagnosis or relapse. The management of such specific complications relies on urgent chemotherapy and eventual instrumental or surgical procedures, combined with advanced life support. We conducted a multicenter study to address the prognosis of this condition. A multicenter retrospective (2001-2015) chart review. Medical and respiratory ICUs. Adult patients who received urgent chemotherapy in the ICU for organ failure related to solid neoplasms were included. The modalities of chemotherapy, requirements of adjuvant instrumental or surgical procedures, and organ supports were collected. Endpoints were short- and long-term survival rates. None. One hundred thirty-six patients were included. Lung cancer was the most common malignancy distributed into small cell lung cancer (n = 57) and non-small cell lung cancer (n = 33). The main reason for ICU admission was acute respiratory failure in 111 patients (81.6%), of whom 89 required invasive mechanical ventilation. Compression and tissue infiltration by tumor cells were the leading mechanisms resulting in organ involvement in 78 (57.4%) and 47 (34.6%) patients. The overall in-ICU, in-hospital, 6-month, and 1-year mortality rates were 37%, 58%, 74%, and 88%, respectively. Small cell lung cancer was identified as an independent predictor of hospital survival. However, this gain in survival was not sustained since the 1-year survival rates of small cell lung cancer, non-small cell lung cancer, and non-lung cancer patients all dropped below 20%. Urgent chemotherapy along with aggressive management of organ failures in the ICU can be lifesaving in very selected cancer patients, most especially with small cell lung cancer, although the long-term survival is hardly sustainable.

Physical methods for treating fever in children.

Health workers recommend bathing, sponging and other physical methods to treat fever in children and to avoid febrile convulsions. We know little about the most effective methods, or how these methods compare with commonly used drugs. To evaluate the benefits and harms of physical cooling methods used for managing fever in children. We searched the Cochrane Infectious Diseases Group specialized trials register (February 2003), the Cochrane Central Register of Controlled Trials (Issue 1, 2003), MEDLINE (1966 to February 2003), EMBASE (1988 to November 2002), CINHAL (1982 to February 2003), LILACS (February 2003), Science Citation Index (1981 to February 2003), and reference lists of articles. We also contacted researchers in the field. Randomized and quasi-randomized trials comparing physical methods with a drug placebo or no treatment in children with fever of presumed infectious origin. Studies where children in both groups were given an antipyretic drug were included. Two reviewers independently assessed trial methodological quality. One reviewer extracted data and the other checked the data for accuracy. Results were expressed as Relative Risk (RR) with 95% confidence intervals (CI) for discrete variables, and weighted mean differences for continuous outcomes. Seven trials, involving 467 participants, met the inclusion criteria. One small trial (n = 30), comparing physical methods with drug placebo, did not demonstrate a difference in the proportion of children without fever by one hour after treatment in a comparison between physical methods alone and drug placebo. In 2 studies, where all children received an anti-pyretic drug, physical methods resulted in a higher proportion of children without fever at one hour (n=125, RR 11.8, CI 3.39 to 40.8). I; in a third study (n=130), which only reported mean change in temperature, no differences wereas detected. Mild adverse events (shivering and goose pimples) were more common in the physical methods group (3 trials, RR 5.09; CI 1.56 to 16.60). A few small studies demonstrate that tepid sponging helps to reduce fever in children.

Multiple tuberculous nodules with metachronous changes: a case report

PubMed Central

2013-01-01

Background Spontaneous regression of lesions occurs in non-infectious benign diseases, such as sarcoidosis, as well as in infectious diseases, such as tuberculosis. Lung cancer and malignant lymphoma, on the other hand, rarely follow a similar course. We report a rare case of lung tuberculosis that presented with multiple nodules with metachronous changes in size. Case presentation We describe the case of a 50-year-old immunocompetent Japanese man with pulmonary tuberculosis in the form of multifocal nodules. He came to our hospital because of a chest X-ray abnormality. During the course of observation, some nodules reduced while others enlarged in size. Two years after the first visit, fever and pleural effusion appeared. The sputum examination turned out to be positive for tuberculosis. A course of anti-tubercular agents resolved the pleural effusion and multifocal nodules. Conclusion Differences in the manner of granuloma formation suggest that the local immune response can be different even in the same lung field. PMID:23937966

This report describes four cases involving French expatriates who developed serious health problems while living destitute in Senegal. A 37-year-old man presented with embolism-like symptoms in relation with lung involvement due to spreading of untreated staphylococcal skin infection. A 64-year-old man was admitted for high output cardiac failure secondary to severe anemia caused by malnutrition. A 50-year-old man presented recurrent fever with loss of consciousness after successful treatment of neuromalaria and finally attributed to delirium tremens. A 25-year-old man was hospitalized with presumed meningoencephalitis that had been ongoing for two weeks. All four patients had been in Senegal for several months and had cut all ties to mainland France. Being jobless and homeless, they had been unable to obtain proper nutrition or medications. With minimal entry requirements and low-cost air travel, Senegal has been come a common sight-seeing destination and has developed a small but apparently growing population of destitute travelers. Alienation from the home community and resulting seclusion enhance clinical consequences and delay intervention by foreign service officials.

Adachi, S; Takemoto, K

1987-09-01

Many epidemiological and experimental studies have suggested that the respiratory tract is one of the most sensitive organs to environmental carcinogens. Nevertheless there is little evidence to determine the relationship between a specific environmental carcinogen and a cell type of lung cancer, because the cell types of lung cancer and their relative frequencies are highly complex compared with those of other organs and tissues. In the present paper, occupational lung-cancer characteristics, which are the clearest in the relation between cause and effect in human lung cancers, were reviewed in comparison with the results of animal experiments concerned with occupational lung carcinogens. Through accumulation of histopathological examinations of the lung cancer cases, the following relationships between cause and cell type were conjectured: chromium and squamous cell carcinoma; asbestos and adenocarcinoma; nickel and squamous cell carcinoma; beryllium and small cell carcinoma; bis (chloromethyl) ether and small cell carcinoma; mustard gas and squamous cell or small cell carcinoma; vinyl chloride and large cell or adenocarcinoma; radionuclides and small cell carcinoma. The relation pertaining to arsenic, benzotrichloride and tar could not be conjectured because of insufficient cases and information in the histological diagnosis. On the other hand, the carcinogenicity of these substances in occupational exposure has been confirmed by animal experiments administered intratracheally or by inhalation studies under relatively higher concentration. As a result of recent refinements of inhalation study, all-day and life-span exposure to extremely low concentrations, such as microgram/m3 orders, of certain substances has been possible. The characteristics of lung tumors occurring in these animals are rather different from those of human. For example, in mouse, almost all of the malignant lung tumors developed by carcinogens are adenocarcinomas and it is rare to find the squamous cell carcinoma. Moreover, small cell carcinoma and large cell carcinoma have not known to occur in the lungs of rats and mice. Therefore, future research should focus elucidating the specific relationship between cause and cell type of human lung cancer by means of animal experiments on lung cancer that give attention to the specificities of each experimental animal and the origin of the resultant lung tumor.

The spread of pathogens through trade in small ruminants and their products.

PubMed

Sherman, D M

2011-04-01

While the international trade in small ruminants and small ruminant products is small relative to the trade in bovine, swine and poultry products, it is still economically important. In addition to wool, it includes some unique products (such as goat and sheep milk cheeses, cashmere fibre and karakul pelts) and the sheep/goat meat trade plays a large part in sustaining livelihoods in several regions of the world. The trade in small ruminants and their products also merits consideration because sheep and goats may transmit zoonotic diseases such as Rift Valley fever, Crimean Congo haemorrhagic fever, brucellosis and listeriosis. They also may transmit highly infectious livestock diseases, such as peste des petits ruminants, to naïve populations of small ruminants in other countries. This can have dramatic consequences, particularly for poor people whose livelihood often depends on small ruminants. In addition, sheep and goats can serve as an important source of foot and mouth disease (FMD) for cattle. This has enormous global trade implications and it is important, therefore, that sheep and goats be considered in FMD control programmes aimed at improving access to trade.

Caprine herpesvirus 2 (CpHV-2) infection usually induces chronic malignant catarrhal fever (MCF) in sika deer (Cervus nippon), with the primary signs of weight loss, dermatitis and alopecia. Here, we report a case of CpHV-2-associated acute MCF in a sika deer herd raised in an intensive management system distant to the reservoir goats. Affected deer developed clinical signs of high fever (41 °C) followed by nasal discharge and lameness. Severe lesions of hemorrhage, necrosis and infiltration of lymphoid cells could readily be observed in the lung, kidney, heart valves and subcutaneous tissue surrounding a tendon. Etiologically, identical CpHV-2 specific DNA sequences were detected in peripheral blood lymphocyte (PBL) from the affected deer and reservoir goats. In summary, domestic goats were the reservoir of the CpHV-2, which is the causative agent of the outbreak of MCF in the three hinds. The disease was probably transmitted via aerosol infection. In addition, necrosis and inflammation in subcutaneous tissue surrounding a tendon was the reason for lameness. Therefore, MCF should be put into a differential diagnostic list when similar disease occurs in sika deer herds.

Lung cancer occurs with a median age of 69 years. The main cause is cigarette smoking. For both genders lung cancer is the third-most frequent tumor in Germany. While in an operable tumor stage 30-80% of the patients can reach long-term survival, the prognosis in the metastasised stage is unfavourable with a 5-year overall survival rate of 6% for small cell lung cancer (SCLC) and 18% for non-small cell lung cancer (NSCLC). Lung cancer is subject of intense research to improve the outcome. This article gives an overview of current treatment options. © Georg Thieme Verlag KG Stuttgart · New York.

Evaluation of tumor markers expression pattern which determines individual progression parameters is one of the major topics in molecular oncopathology research. This work presents research on expression analysis of several Ras-Ral associated signal transduction pathway proteins (Arf6, RalA and BIRC5) in accordance with clinical criteria in non small cell lung cancer patients. Using Western-blot analysis and RT-PCR Arf6, RalA and BIRC5 expression has been analyzed in parallel in 53 non small cell lung cancer samples of different origin. Arf6 protein expression was elevated in 55% non small cell lung cancer tumor samples in comparison with normal tissue. In the group of squamous cell lung cancer Arf6 expression elevation was observed more often. RalA protein expression was decreased in comparison to normal tissue samples in 64% of non small cell lung cancer regardless to morphological structure. Correlation between RalA protein expression decrease and absence of regional metastases was revealed for squamous cell lung cancer. BIRC5 protein expression in tumor samples versus corresponding normal tissue was 1.3 times more often elevated in the squamous cell lung cancer group (in 76% tumor samples). At the same time elevation of BIRC5 expression was fixed only in 63% of adenocarcinoma tumor samples. A statistically significant decrease (p = 0.0158) of RalA protein expression and increase (p = 0.0498) of Arf6 protein expression in comparison with normal tissue was found for T1-2N0M0 and T1-2N1-2M0 groups of squamous cell lung cancer correspondingly.

Sources of pathogenic Rickettsia in wildlife are largely unknown in Brazil. In this work, potential tick vectors and seroreactivity of small mammals against four spotted-fever group Rickettsia (R. rickettsii, R. parkeri, R. amblyommii and R. rhipicephali) and Rickettsia bellii from peri-urban areas of Uberlândia, a major town in Brazil, are described for the first time. Small mammals were captured and blood samples collected. Ticks were collected from the surface of the host and the environment and posteriorly identified. Reactivity of small mammal sera to Rickettsia was tested by indirect immunofluorescence assay (IFA) using crude antigens from five Brazilian Rickettsia isolates. Information was obtained from 416 small mammals (48 Marsupialia and 368 Rodentia). Forty-eight animals were parasitized and two tick species, Ixodes loricatus and Amblyomma dubitatum, were found on several host species, with a few tick-host relationships described for the first time. From the 416 tested sera, 70 reacted to at least one Rickettsia antigen (prevalence of 16.8%) and from these, 19 (27.1%) reacted to two or more antigens. Seroprevalence was higher for marsupials (39.6%) than for rodents (13.8%). Marsupial and Rhipidomys spp. sera reacted mainly (highest seroprevalence and titers) to R. bellii, and that of Necromys lasiurus mainly to R. rickettsii. Although the serologic assays poorly discriminate between closely related spotted-fever group Rickettsia, the observed small mammal seroreactivity suggests the circulation of Rickettsia in the peri-urban area of Uberlândia, albeit at low levels.

In the post-intervention period of the Women's Health Initiative (WHI) trial, women assigned to treatment with oestrogen plus progestin had a higher risk of cancer than did those assigned to placebo. Results also suggested that the combined hormone therapy might increase mortality from lung cancer. To assess whether such an association exists, we undertook a post-hoc analysis of lung cancers diagnosed in the trial over the entire follow-up period. The WHI study was a randomised, double-blind, placebo-controlled trial undertaken in 40 centres in the USA. 16 608 postmenopausal women aged 50-79 years with an intact uterus were randomly assigned by a computerised, stratified, permuted block algorithm to receive a once-daily tablet of 0.625 mg conjugated equine oestrogen plus 2.5 mg medroxyprogesterone acetate (n=8506) or matching placebo (n=8102). We assessed incidence and mortality rates for all lung cancer, small-cell lung cancer, and non-small-cell lung cancer by use of data from treatment and post-intervention follow-up periods. Analysis was by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00000611. After a mean of 5.6 years (SD 1.3) of treatment and 2.4 years (0.4) of additional follow-up, 109 women in the combined hormone therapy group had been diagnosed with lung cancer compared with 85 in the placebo group (incidence per year 0.16%vs 0.13%; hazard ratio [HR] 1.23, 95% CI 0.92-1.63, p=0.16). 96 women assigned to combined therapy had non-small-cell lung cancer compared with 72 assigned to placebo (0.14%vs 0.11%; HR 1.28, 0.94-1.73, p=0.12). More women died from lung cancer in the combined hormone therapy group than in the placebo group (73 vs 40 deaths; 0.11%vs 0.06%; HR 1.71, 1.16-2.52, p=0.01), mainly as a result of a higher number of deaths from non-small-cell lung cancer in the combined therapy group (62 vs 31 deaths; 0.09%vs 0.05%; HR 1.87, 1.22-2.88, p=0.004). Incidence and mortality rates of small-cell lung cancer were similar between groups. Although treatment with oestrogen plus progestin in postmenopausal women did not increase incidence of lung cancer, it increased the number of deaths from lung cancer, in particular deaths from non-small-cell lung cancer. These findings should be incorporated into risk-benefit discussions with women considering combined hormone therapy, especially those with a high risk of lung cancer.

Pleiotrophin is a heparin-binding growth factor involved in the differentiation and proliferation of neuronal tissue during embryogenesis, and also secreted by melanoma and breast carcinoma cells. Pleiotrophin exhibits mitogenic and angiogenic properties and has been shown to influence the vascular supply, expansion and metastasis of tumour cells. Our aim was to study the serum and plasma concentrations of pleiotrophin and the classical angiogenic growth factor vascular endothelial growth factor. Using a specific ELISA-test we studied patients with small cell lung cancer (n=63), and patients with non-small cell lung cancer (n=22) in comparison to healthy control subjects (n=41). In most of the lung cancer patients (81%), we found serum levels of pleiotrophin above those of control subjects (P<0.001). Of the 63 small cell lung cancer patients in the study pleiotrophin serum levels were elevated in 55 cases (87%) and in 14 cases (63%) of the 22 non-small cell lung cancer patients. Pleiotrophin mean serum concentrations were 10.8-fold higher in the tumour patient group as compared to the control group (P<0.001). Furthermore, pleiotrophin serum levels correlated positively with the stage of disease and inversely with the response to therapy. Plasma vascular endothelial growth factor concentrations were elevated in only in 28.6% of small cell lung cancer and 45.5% of non-small cell lung cancer patients by an average of 2.3-fold. Quite strikingly, there was no apparent correlation between the plasma vascular endothelial growth factor concentration and the stage of disease. Our study suggests that pleiotrophin may be an early indicator of lung cancer and might be of use in monitoring the efficacy of therapy, which needs to be confirmed by larger studies.

To examine whether maternal fever during pregnancy is associated with reduced head circumference and risk of microcephaly at birth. A prospective study of 86,980 live-born singletons within the Danish National Birth Cohort was carried out. Self-reported maternal fever exposure was ascertained in two interviews during pregnancy and information on head circumference at birth was extracted from the Danish Medical Birth Registry. Fever in pregnancy was reported by 27% of the mothers, and we identified 3370 cases of microcephaly (head circumference less than or equal to third percentile for sex and gestational age) and 1140 cases of severe microcephaly (head circumference less than or equal to first percentile for sex and gestational age). In this study, maternal fever exposure was not associated with reduced head circumference (adjusted β = 0.03, 95% confidence intervals [CI]: 0.01-0.05), increased risk of microcephaly (odds ratio: 0.95, 95% CI: 0.88-1.03) nor severe microcephaly (odds ratio: 1.01, 95% CI: 0.88-1.15) in the offspring. These findings were consistent for increasing numbers of fever episodes, for increasing fever severity, and for exposure in both early pregnancy and midpregnancy. In this most comprehensive study to date, we found no indication that maternal fever in pregnancy is associated with small head size in the offspring. Copyright © 2017 Elsevier Inc.

This study examines prevalence of respiratory conditions in New Orleans-area restoration workers after Hurricane Katrina. Between 2007 and 2010, spirometry and respiratory health and occupational questionnaire were administered to 791 New Orleans-area adults who mostly worked in the building construction and maintenance trades or custodial services. The associations between restoration work hours and lung function and prevalence of respiratory symptoms were examined by multiple linear regression, χ², or multiple logistic regression. 74% of participants performed post-Katrina restoration work (median time: 620 hours). Symptoms reported include episodes of transient fever/cough (29%), sinus symptoms (48%), pneumonia (3.7%), and new onset asthma (4.5%). Prevalence rate ratios for post-Katrina sinus symptoms (PRR = 1.3; CI: 1.1, 1.7) and fever and cough (PRR = 1.7; CI: 1.3, 2.4) were significantly elevated overall for those who did restoration work and prevalence increased with restoration work hours. Prevalence rate ratios with restoration work were also elevated for new onset asthma (PRR = 2.2; CI: 0.8, 6.2) and pneumonia (PRR = 1.3; CI: 0.5, 3.2) but were not statistically significant. Overall, lung function was slightly depressed but was not significantly different between those with and without restoration work exposure. Post-Katrina restoration work is associated with moderate adverse effects on respiratory health, including sinusitis and toxic pneumonitis.

Haematological patients with neutropenic fever are frequently evaluated with chest computed tomography (CT) to rule out invasive fungal infections (IFI). We retrospectively analysed data from 100 consecutive patients with neutropenic fever and abnormal chest CT from 1998 to 2005 to evaluate their chest CT findings and the yield of diagnostic approaches employed. For their initial CTs, 79% had nodular opacities, with 24.1% associated with the halo sign. Other common CT abnormalities included pleural effusions (48%), ground glass opacities (37%) and consolidation (31%). The CT findings led to a change in antifungal therapy in 54% of the patients. Fifty-six patients received diagnostic procedures, including 46 bronchoscopies, 25 lung biopsies and seven sinus biopsies, with a diagnostic yield for IFI of 12.8%, 35.0% and 83.3%, respectively. In conclusion, chest CT plays an important role in the evaluation of haematological patients with febrile neutropenia and often leads to a change in antimicrobial therapy. Pulmonary nodules are the most common radiological abnormality. Sinus or lung biopsies have a high-diagnostic yield for IFI as compared to bronchoscopy. Patients with IFI may not have sinus/chest symptoms, and thus, clinicians should have a low threshold for performing sinus/chest imaging, and if indicated and safe, a biopsy of the abnormal areas. © 2009 Blackwell Verlag GmbH.

This analysis was conducted to evaluate the efficacy and safety of crizotinib based regimens in treating Chinese patients with EML4-ALK positive non-small-cell lung cancer. Clinical studies evaluating the efficacy and safety of crizotinib based regimens on response and safety for Chinese patients with EML4-ALK positive non-small-cell lung cancer were identified by using a predefined search strategy. Pooled response rate (RR) of treatment were calculated. In crizotinib based regimens, 3 clinical studies which including 128 Chinese patients with EML4-ALK positive non-small-cell lung cancer and treated with crizotinib based regimen were considered eligible for inclusion. Pooled analysis suggested that, in all patients, the pooled RR was 59.3% (76/128) in crizotinib based regimens. ALT/AST mild visual disturbances, nausea, and vomiting were the main side effects. No treatment related death occurred in these crizotinib based treatments. This pooled analysis suggests that crizotinib based regimens are associated with good response rate and accepted toxicities in treating Chinese patients with EML4-ALK positive non-small-cell lung cancer.

A 66-year-old woman was admitted to our hospital because of high fever, general fatigue, hypoxemia and liver dysfunction. Chest radiographs showed diffuse interstitial shadows in both lungs. We suspected drug-induced pneumonitis because of her history of drug administration for upper respiratory infection. Her symptoms and findings were markedly decreased by discontinuation of the drugs. Transbronchial lung biopsy specimens showed infiltration of eosinophils and lymphocytes to the alveolar septa, granuloma with Langhans' giant cells, and Masson bodies in a manner suggestive of hypersensitivity pneumonitis. Drug lymphocyte stimulation tests were negative except for loxoprofen. There was no recurrence of systemic or respiratory symptoms during overnight stays at home. On the basis of these findings, we arrived at a diagnosis of drug-induced pneumonitis caused by loxoprofen.

In Panama, hantavirus pulmonary syndrome (HPS) is caused by Choclo virus, a species phylogenetically related to Andes and Maporal viruses. Up to 60% of the population has been positive for specific serum antibody in community-based surveys, but mortality is very uncommon. In four western Panama clinics, we tested individuals presenting with a severe febrile prodrome for acute hantavirus (HV) infection by immunoglobulin M enzyme-linked immunosorbent assay and reverse transcription polymerase chain reaction as well as clinically similar infections, such as dengue and leptospirosis. From 2006 to 2009, at least 21% of 117 patients diagnosed with HV infection had HV Fever (HF) with no evidence of pulmonary edema (no respiratory distress or radiographic lung infiltrates), and 44% of patients had very mild HPS (radiographic pulmonary edema but no respiratory insufficiency). HV infection caused by Choclo virus in Panama presents often as HF, which contrasts with HV in the Americas but is consistent with the high seroprevalence in endemic regions.

A hantavirus causing hemorrhagic fever with renal syndrome requires gC1qR/p32 for efficient cell binding and infection

DOE Office of Scientific and Technical Information (OSTI.GOV)

Choi, Yun; Kwon, Young-Chan; Kim, Soo-In

Hantaan virus (HTNV) is a pathogenic hantavirus that causes hemorrhagic fever with renal syndrome (HFRS). HTNV infection is mediated by {alpha}v{beta}3 integrin. We used protein blots of Vero E6 cell homogenates to demonstrate that radiolabeled HTNV virions bind to gC1qR/p32, the acidic 32-kDa protein known as the receptor for the globular head domain of complement C1q. RNAi-mediated suppression of gC1qR/p32 markedly reduced HTNV binding and infection in human lung epithelial A549 cells. Conversely, transient expression of either simian or human gC1qR/p32 rendered non-permissive CHO cells susceptible to HTNV infection. These results suggest an important role for gC1qR/p32 in HTNV infectionmore » and pathogenesis.« less

Pontiac fever, a unique epidemiologic form of legionellosis, is characterized by a short (one- to two-day) incubation period and a self-limited grippe-like illness without pneumonia. In 1968, the first documented outbreak of this syndrome affected persons who had entered a health department building in Pontiac, Michigan. Epidemiologic analyses clearly implicated as airborne agent and suggested that evaporative condenser water aerosols being disseminated by a defective air conditioning system played a key role in the outbreak. Guinea pigs that were exposed in the building and to laboratory aerosols of evaporative condenser water developed bronchopneumonia. Legionella pneumophilia (serogroup 1) was isolated from the exposed guinea pigs' lungs. Paired acute and convalescent serum specimens from 37 patients were tested by the indirect fluorescent antibody technique using L. pneumophila serogroup 1 antigen, and 31 (84%) had rises in titer from less than 32 to greater than or equal to 64.

A new sensitive method for detecting human endogenous (leukocyte) pyrogen.

PubMed

Bodel, P; Miller, H

1978-03-01

Endogenous, or leukocyte pyrogen (EP), the mediator of fever, is currently detected by injection of pyrogen-containing supernatants into rabbits. This assay has been of little value in the study of human fever because it required injection of relatively large amounts of pyrogen. We now report that injection of medium containing human EP produces fever in mice. Supernatant from 1 c 10(5) granulocytes, stimulated by phagocytosis of staphylococci and incubated overnight, or 1 x 10(4) monocytes similarly treated, produce clear pyrogenic responses. This method for detecting EP is about 100-fold more sensitive than the rabbit assay, and it appears to be specific for EP. Preliminary studies of EP released by small samples of needle liver biopsies from febrile and afebrile patients suggests that this sensitive assay may be useful for investigations into the mechanisms of clinical fever.

While the association between exposure to secondhand smoke and lung cancer risk is well established, few studies with sufficient power have examined the association by histological type. In this study, we evaluated the secondhand smoke-lung cancer relationship by histological type based on pooled data from 18 case-control studies in the International Lung Cancer Consortium (ILCCO), including 2,504 cases and 7,276 controls who were never smokers and 10,184 cases and 7,176 controls who were ever smokers. We used multivariable logistic regression, adjusting for age, sex, race/ethnicity, smoking status, pack-years of smoking, and study. Among never smokers, the odds ratios (OR) comparing those ever exposed to secondhand smoke with those never exposed were 1.31 (95% CI: 1.17–1.45) for all histological types combined, 1.26 (95% CI: 1.10–1.44) for adenocarcinoma, 1.41 (95% CI: 0.99–1.99) for squamous cell carcinoma, 1.48 (95% CI: 0.89–2.45) for large cell lung cancer, and 3.09 (95% CI: 1.62–5.89) for small cell lung cancer. The estimated association with secondhand smoke exposure was greater for small cell lung cancer than for non-small cell lung cancers (OR=2.11, 95% CI: 1.11–4.04). This analysis is the largest to date investigating the relation between exposure to secondhand smoke and lung cancer. Our study provides more precise estimates of the impact of secondhand smoke on the major histological types of lung cancer, indicates the association with secondhand smoke is stronger for small cell lung cancer than for the other histological types, and suggests the importance of intervention against exposure to secondhand smoke in lung cancer prevention.

Northern Côte d'Ivoire is the main livestock breeding zone and has the highest livestock cross-border movements in Côte d'Ivoire. The aim of this study was to provide updated epidemiological data on three neglected zoonotic diseases, namely brucellosis, Q Fever and Rift Valley Fever (RVF). We conducted three-stage cross-sectional cluster surveys in livestock and humans between 2012 and 2014 in a random selection of 63 villages and a sample of 633 cattle, 622 small ruminants and 88 people. We administered questionnaires to capture risk factors and performed serological tests including the Rose Bengal Plate Test (RBPT), Brucella spp. indirect and competitive ELISAs, Coxiella burnetii indirect ELISA and RVF competitive ELISA. The human seroprevalence for Brucella spp. was 5.3%. RBPT-positive small ruminants tested negative by the indirect ELISA. The seroprevalence of Brucella spp. in cattle adjusted for clustering was 4.6%. Cattle aged 5-8 years had higher odds of seropositivity (OR=3.5) than those aged ≤4years. The seropositivity in cattle was associated with having joint hygromas (OR=9), sharing the pastures with small ruminants (OR=5.8) and contact with pastoralist herds (OR=11.3). The seroprevalence of Q Fever was 13.9% in cattle, 9.4% in sheep and 12.4% in goats. The seroprevalence of RVF was 3.9% in cattle, 2.4% in sheep and 0% in goats. Seropositive ewes had greater odds (OR=4.7) of abortion than seronegative ones. In cattle, a shorter distance between the night pens and nearest permanent water bodies was a protective factor (OR=0.1). The study showed that the exposure to the three zoonoses is rather low in northern Côte d'Ivoire. Within a One Health approach, cost-benefit and cost-effectiveness of control measures should be assessed for an integrated control. Copyright © 2017 Elsevier B.V. All rights reserved.

Northern Côte d'Ivoire is the main livestock breeding zone and has the highest livestock cross-border movements in Côte d'Ivoire. The aim of this study was to provide updated epidemiological data on three neglected zoonotic diseases, namely brucellosis, Q Fever and Rift Valley Fever (RVF). We conducted three-stage cross-sectional cluster surveys in livestock and humans between 2012 and 2014 in a random selection of 63 villages and a sample of 633 cattle, 622 small ruminants and 88 people. We administered questionnaires to capture risk factors and performed serological tests including the Rose Bengal Plate Test (RBPT), Brucella spp. indirect and competitive ELISAs, Coxiella burnetii indirect ELISA and RVF competitive ELISA.

Positron-emission tomography (PET) with F18-fluorodeoxyglucose (FDG) is very helpful in the evaluation and management of lung lesions. It is specially useful for the characterization of solitary nodules, for the staging, evaluation of recurrence and therapeutic response in non-small cell lung cancer, for the evaluation of small cell lung cancer and for the assessment of pulmonary metastases. This article is a literature review on PET with FDG in lung cancer. A preliminary analysis of PET results at the Military Hospital in Santiago, Chile, is also presented.

The role of adjuvant chemotherapy for non-small-cell lung cancer (NSCLC) stage I patients with tumors size ≥4 cm is not well established in the elderly. We identified 3289 patients with stage I NSCLC (T2N0M0 and tumor size ≥4 cm) who underwent lobectomy from the Surveillance, Epidemiology and End Results (SEER)-Medicare linked database diagnosed from 1992 to 2009. Overall survival and rates of serious adverse events (defined as those requiring admission to hospital) were compared between patients treated with resection alone, platinum-based adjuvant chemotherapy, or postoperative radiation (PORT) with or without adjuvant chemotherapy. Propensity scores for receiving each treatment were calculated and survival analyses were conducted using inverse probability weights based on the propensity score. Overall, 84% patients were treated with resection alone, 9% received platinum-based adjuvant chemotherapy, and 7% underwent PORT with or without adjuvant chemotherapy. Adjusted analysis showed that adjuvant chemotherapy [hazard ratio (HR), 0.82; 95% confidence interval (CI) 0.68-0.98] was associated with improved survival compared with resection alone. Conversely, the use of PORT with or without adjuvant chemotherapy (HR 1.91; 95% CI 1.64-2.23) was associated with worse outcomes. Patients receiving adjuvant chemotherapy had more serious adverse events compared with those treated with resection alone, with neutropenia (odds ratio, 21.2; 95% CI 5.8-76.6) being most significant. No significant difference was observed in rates of fever, cytopenias, nausea, and renal dysfunction. Platinum-based adjuvant chemotherapy is associated with reduced mortality and increased serious adverse events in elderly patients with stage I NSCLC and tumor size ≥4 cm. © The Author 2015.

Forty-seven previously untreated patients with histologically or cytologically proven non-small cell lung cancer were treated with ICE (ifosfamide/cisplatin/etoposide). Patients received ifosfamide 4 g/m2 with mesna uroprotection on day 1, and cisplatin 25 mg/m2/d and etoposide 100 mg/m2/d on days 1, 2, and 3; courses were repeated every 28 days. Premedication with prochlorperazine, dexamethasone, and high-dose metoclopramide was given to prevent nausea; lorazepam was added on days 2 and 3 only. Thirty-four men and 13 women (median age, 60 years) received a total of 146 treatment cycles. One patient had stage IIIA disease, seven had IIIB disease, and 39 had hematogenous metastases. Forty-six patients were evaluable for response and toxicity. One patient suffered a myocardial infarction on day 7 that was judged unrelated to treatment. Two patients suffered early death from toxicity and have been classified as nonresponders. Three patients achieved complete response (median, 42+ weeks) and 14 patients achieved partial response (median, 29+ weeks; range, 10 to 82+), for an overall response rate of 37% (95% confidence limits, 23% to 51%). The median survival of the entire group is 26 weeks (1 to 82+). The median nadir granulocyte count was 0.275 x 10(9)/L (range, 0 to 2.3 x 10(9)/L), and there were 14 episodes (in 11 patients) or neutropenia-associated fever, one of which resulted in death. Seven of these patients had not had the required protocol dose reduction for nadir neutrophil count in the preceding cycle. The median nadir platelet count was 120 x 10(9)/L (range, 13 to 385 x 10(9)/L), and three patients required platelet transfusions. Eleven patients had RBC transfusions. Only ten patients had grade 2 gastrointestinal toxicity. Five patients had microscopic hematuria, and one patient had central nervous system toxicity.

EGFR is a well-validated target for patients with non-small cell lung cancer (NSCLC). CIMAvax-EGF is a therapeutic cancer vaccine composed of human recombinant EGF conjugated to a carrier protein and Montanide ISA51 as adjuvant. The vaccine is intended to induce antibodies against self EGFs that block EGF-EGFR interaction. To evaluate overall survival, safety, immunogenicity, and EGF concentration in serum after CIMAvax-EGF, a randomized phase III trial was done in patients with advanced NSCLC. Four to 6 weeks after first-line chemotherapy, 405 patients with stage IIIB/IV NSCLC were randomly assigned to a vaccine group, which received CIMAvax-EGF or a control group, treated with best supportive care. Long-term vaccination was very safe. Most frequent adverse reactions were grade 1 or 2 injection-site pain, fever, vomiting, and headache. Vaccination induced anti-EGF antibodies and decreased serum EGF concentration. In the safety population, median survival time (MST) was 10.83 months in the vaccine arm versus 8.86 months in the control arm. These differences were not significant according the standard log rank (HR, 0.82; P = 0.100), but according a weighted log rank (P = 0.04) that was applied once the nonproportionality of the HR was verified. Survival benefit was significant (HR, 0.77; P = 0.036) in the per-protocol setting (patients receiving at least four vaccine doses): MST was 12.43 months for the vaccine arm versus 9.43 months for the control arm. MST was higher (14.66 months) for vaccinated patients with high EGF concentration at baseline. Switch maintenance with CIMAvax-EGF was well tolerated and significantly increased MST of patients that completed induction vaccination. Baseline EGF concentration predicted survival benefit.

African swine fever (ASF), a disease notifiable to the World Organization of Animal Health (OIE), is characterized by severe, unspecific clinical signs and high mortality rates. Hosts for ASF virus (ASFV) are only members of the family Suidae and soft ticks of the genus Ornithodoros. Currently, no vaccine is available and therefore, the control is primarily based on strict sanitary measures. The most important part is the early detection of the disease within affected animal holdings and the fast and reliable confirmation by laboratory diagnosis. Infections of domestic pigs and European wild boar with recent Armenian, Sardinian, Lithuanian or Kenyan ASFV isolates lead to severe, acute disease courses with the predominant symptom of high fever (> 41 degrees C) accompanied by further unspecific clinical signs such as lethargy, loss of appetite, diarrhoea, respiratory symptoms, and an increased bleeding tendency. In experimental infection studies the mortality rate reached 100%. The most prominent pathomorphological findings included ebony-colored gastrohepatic lymph nodes, lung oedema, petechiae in the renal cortex, and oedema of the gallbladder wall. In the light of the current epidemiological situation with endemic ASFV infections on Sardinia, outbreaks in Russia and several Eastern EU Member States there is a risk for an introduction in further, previously unaffected EU countries including Germany. Hence, appropriate sample materials (serum, blood, spleen) of domestic pigs with unspecific clinical symptoms or pathomorphological findings should be examined for both ASFV and classical swine fever virus.

A 9-year-old boy was admitted to Xiangya Hospital due to pain after trauma in the left lower limb for 5 days and fever with generalized pain for 2 days. The results of X-ray of the left lower limb were normal. Pulmonary computed tomography (CT) showed multiple pulmonary nodules in both lungs. Adrenal CT showed marked enlargement of the left adrenal gland. The patient also experienced generalized herpes and intermittent delirium and had a blood pressure up to 155/93 mm Hg. He was transferred to our hospital with a suspected diagnosis of pheochromocytoma. On admission, the patient had a blood pressure of 86/44 mm Hg, sporadic maculopapule and herpes, touch-evoked pain, exposure of superficial veins, white pus coating on the right side of the tongue, and tension in the abdominal muscle. No skin damage was observed in the left lower limb, and the patient was forced to be in the extending position and experienced significant swelling below the knees. Laboratory examination showed a reduction in platelet count, hypoproteinemia, a significant increase in creatase, a C-reactive protein level of 348 mg/L, and a procalcitonin level of >100 ng/mL. Thoracoabdominal and pelvic CT showed multiple patchy and nodular lesions in both lungs, which had an undetermined nature, as well as an enlarged spleen. The tests of puncture fluid from the left knee joint and the periosteum of the left tibia, blood culture, and bone marrow culture all showed methicillin-resistant Staphylococcus aureus. The patient was given anti-shock treatment, anti-infective therapy with vancomycin, debridement and continuous irrigation/drainage of osteomyelitis lesions in the left tibia, but the patient still experienced recurrent shivering and severe fever and increased subcutaneous and pulmonary nodules. Linezolid was added on day 8 after admission, and the patient's body temperature returned to normal on day 24 after admission. Subcutaneous and pulmonary nodules were gradually reduced and disappeared. The patient was treated for 2 months and then evaluated as cured.

Enhanced expression of G-protein coupled estrogen receptor (GPER/GPR30) in lung cancer

PubMed Central

2012-01-01

Background G-protein-coupled estrogen receptor (GPER/GPR30) was reported to bind 17β-estradiol (E2), tamoxifen, and ICI 182,780 (fulvestrant) and promotes activation of epidermal growth factor receptor (EGFR)-mediated signaling in breast, endometrial and thyroid cancer cells. Although lung adenocarcinomas express estrogen receptors α and β (ERα and ERβ), the expression of GPER in lung cancer has not been investigated. The purpose of this study was to examine the expression of GPER in lung cancer. Methods The expression patterns of GPER in various lung cancer lines and lung tumors were investigated using standard quantitative real time PCR (at mRNA levels), Western blot and immunohistochemistry (IHC) methods (at protein levels). The expression of GPER was scored and the pairwise comparisons (cancer vs adjacent tissues as well as cancer vs normal lung tissues) were performed. Results Analysis by real-time PCR and Western blotting revealed a significantly higher expression of GPER at both mRNA and protein levels in human non small cell lung cancer cell (NSCLC) lines relative to immortalized normal lung bronchial epithelial cells (HBECs). The virally immortalized human small airway epithelial cell line HPL1D showed higher expression than HBECs and similar expression to NSCLC cells. Immunohistochemical analysis of tissue sections of murine lung adenomas as well as human lung adenocarcinomas, squamous cell carcinomas and non-small cell lung carcinomas showed consistently higher expression of GPER in the tumor relative to the surrounding non-tumor tissue. Conclusion The results from this study demonstrate increased GPER expression in lung cancer cells and tumors compared to normal lung. Further evaluation of the function and regulation of GPER will be necessary to determine if GPER is a marker of lung cancer progression. PMID:23273253

Yellow fever, Asia and the East African slave trade.

PubMed

Cathey, John T; Marr, John S

2014-05-01

Yellow fever is endemic in parts of sub-Saharan Africa and South America, yet its principal vectors--species of mosquito of the genus Aedes--are found throughout tropical and subtropical latitudes. Phylogenetic analyses indicate that yellow fever originated in Africa and that its spread to the New World coincided with the slave trade, but why yellow fever has never appeared in Asia remains a mystery. None of several previously proposed explanations for its absence there is considered satisfactory. We contrast the trans-Atlantic slave trade, and trade across the Sahara and to the Arabian Peninsula and Mesopotamia, with that to Far East and Southeast Asian ports before abolition of the African slave trade, and before the scientific community understood the transmission vector of yellow fever and the viral life cycle, and the need for shipboard mosquito control. We propose that these differences in slave trading had a primary role in the avoidance of yellow fever transmission into Asia in the centuries before the 20(th) century. The relatively small volume of the Black African slave trade between Africa and East and Southeast Asia has heretofore been largely ignored. Although focal epidemics may have occurred, the volume was insufficient to reach the threshold for endemicity.

Changes in WIFI expression, an extracellular inhibitor of Wnt pathway, in non-small cell lung carcinomas were analyzed. Frequent (67% cases) suppression of WIFI transcript in non-small cell lung carcinomas were found. Our results, together with previously published data, suggest that inhibition of WIFI expression often occurs in squamous cell carcinomas and is less typical of adenocarcinomas. It was also found that a decrease in the WIFI transcript in tumors is parallel to concomitant suppression of the WIFI protein level. Our results provide further evidence that the WIFI suppression is a frequent event in the lung carcinogenesis, which might lead to disregulation of Wnt signaling pathway and contribute to tumor progression.

Lung cancer causes over one million deaths every year worldwide. However, prevention and treatment methods for this serious disease are limited. The identification of new chemicals related to lung cancer may aid in disease prevention and the design of more effective treatments. This study employed a weighted network, constructed using chemical-chemical interaction information, to identify new chemicals related to two types of lung cancer: non-small lung cancer and small-cell lung cancer. Then, a randomization test as well as chemical-chemical interaction and chemical structure information were utilized to make further selections. A final analysis of these new chemicals in the context of the current literature indicates that several chemicals are strongly linked to lung cancer. PMID:26047514

This study was performed to clarify whether preoperative serum albumin level is related to the prognosis of non-small cell lung cancer patients undergoing surgical resection, and the relationships between serum albumin level and clinicopathological characteristics of lung cancer patients with emphysema or pulmonary fibrosis. We retrospectively evaluated 556 patients that underwent surgical resection for non-small cell lung cancer. The correlation between preoperative serum albumin level and survival was evaluated. Patients were divided into three groups according to the findings on chest high-resolution computed tomography (normal lung, emphysema, and pulmonary fibrosis), and the relationships between serum albumin level and clinicopathological characteristics, including prognosis, were evaluated. The cut-off value of serum albumin level was set at 4.2g/dL. Patients with low albumin levels (albumin <4.2) had significantly poorer prognosis than those with high albumin levels (albumin ≥4.2) with regard to both overall survival and recurrence-free survival. Serum albumin levels in the emphysema group (n=48) and pulmonary fibrosis group (n=45) were significantly lower than that in the normal lung group (n=463) (p=0.009 and <0.001, respectively). Low serum albumin level was a risk factor in normal lung and pulmonary fibrosis groups, but not in the emphysema group. Preoperative serum albumin level was an important prognostic factor for overall survival and recurrence-free survival in patients with resected non-small cell lung cancer. Divided into normal lung, emphysema, and pulmonary fibrosis groups, serum albumin level showed no influence only in patients in the emphysema group. Copyright © 2017 Elsevier B.V.

Authors present actual overview of information on diagnostic and therapeutic procedures in small-cell lung cancer (SCLC). This highly aggressive type of lung cancer is diagnosed in 14.8 % of Czech lung cancer patients. Vast majority of those patients (87 %) suffer from advanced and metastatic disease in the time of diagnosis. In this issue are presented prognostic factors, staging diagnostic procedures and therapeutic recommendations. The backbone of actual SCLC treatment is combined chemotherapy and radiotherapy and less frequently, carefully in selected cases, surgical procedures. SCLC should be have as chemosensitive, chemoresistent or chemorefractory disease. Actual cytostatic combinations used in 1st line treatment, different schedules of chemoradiotherapy, drugs used in second line treatment and schedules and timing of prophylactic brain irradiation are presented. In near future, perspectively, there are some promissible data on antitumour immunotherapy based on anti CTLA-4 and anti PD-1/PE-L1 antibodies also in SCLC patients.Key words: cancer immunotherapy - concomitant chemoradiotherapy - chemotherapy - chest radiotherapy - lung resections - prophylactic brain irradiation - small cell lung cancer.

Prohormone convertase and autocrine growth factor mRNAs are coexpressed in small cell lung carcinoma.

PubMed

Rounseville, M P; Davis, T P

2000-08-01

A hallmark of small cell lung carcinoma (SCLC) is the expression of autocrine growth factors such as neurotensin and gastrin-releasing peptide, which bind to cellular receptors and stimulate cell division. The biological activity of autocrine growth factors requires the concurrent expression of prohormone convertases that cleave the growth factors to their active form, suggesting the expression of these genes is linked in SCLCs. RNase protection assays were used to detect the expression of autocrine growth factor and prohormone convertase mRNAs in a panel of lung cancer cell lines. These mRNAs are coexpressed in SCLC and lung carcinoid cell lines, but not in normal lung epithelium or in non-small cell lung cancers. These findings, together with earlier results from our laboratory, suggest the expression of prohormone convertases has an important role in the development and maintenance of the SCLC phenotype and that autocrine growth factor and prohormone convertase genes respond to a common transcriptional activator in SCLC.

Carfilzomib (CFZ) is a proteasome inhibitor that selectively and irreversibly binds to its target and has been approved in the US for treatment of relapsed and refractory multiple myeloma. Phase 1B studies of CFZ reported signals of clinical activity in solid tumors, including small cell lung cancer (SCLC). The aim of this study was to investigate the activity of CFZ in lung cancer models. A diverse panel of human lung cancer cell lines and a SHP77 small cell lung cancer xenograft model were used to investigate the anti-tumor activity of CFZ. CFZ treatment inhibited both the constitutive proteasome and the immunoproteasome in lung cancer cell lines. CFZ had marked anti-proliferative activity in A549, H1993, H520, H460, and H1299 non-small cell lung cancer (NSCLC) cell lines, with IC50 values after 96 hour exposure from <1.0 nM to 36 nM. CFZ had more variable effects in the SHP77 and DMS114 SCLC cell lines, with IC50 values at 96 hours from <1 nM to 203 nM. Western blot analysis of CFZ-treated H1993 and SHP77 cells showed cleavage of poly ADP ribose polymerase (PARP) and caspase-3, indicative of apoptosis, and induction of microtubule-associated protein-1 light chain-3B (LC3B), indicative of autophagy. In SHP77 flank xenograft tumors, CFZ monotherapy inhibited tumor growth and prolonged survival, while no additive or synergistic anti-tumor efficacy was observed for CFZ + cisplatin (CDDP). CFZ demonstrated anti-proliferative activity in lung cancer cell lines in vitro and resulted in a significant survival advantage in mice with SHP77 SCLC xenografts, supporting further pre-clinical and clinical investigations of CFZ in NSCLC and SCLC.

Purpose Information on the clinical features of lung abscess, which is uncommon in children, at hospitalizationis helpful to anticipate the disease course and management. There is no report concerning lung abscess in Korean children. We aimed to identify the clinical characteristics of pediatric lung abscess and compare the difference between primary and secondary abscess groups. Methods The medical records of 11 lung abscess patients (7 males and 4 females) from March 1998 to August 2011 at two university hospitals were retrospectively reviewed. The clinical characteristics, symptoms, underlying disease, laboratory and radiologic findings, microbiological results, and treatments were examined. Results Six patients had underlying structural-related problems (e.g., skeletal anomalies). No immunologic or hematologic problem was recorded. The mean ages of the primary and secondary groups were 2.4 and 5.3 years, respectively, but the difference was not statistically significant. The mean length of hospital stay was similar in both groups (22.8 days vs. 21.4 days). Immunologic studies were performed in 3 patients; the results were within the normal range. Most patients had prominent leukocytosis. Seven and 4 patients had right and left lung abscess, respectively. Staphylococcus aureus, Streptococcus pneumoniae, and antimycoplasma antibodies were detected in both groups. Two patients with primary lung abscess were administered antibiotics in the absence of other procedures, while 8 underwent interventional procedures, including 5 with secondary abscess. Conclusion The most common symptoms were fever and cough. All patients in the primary group were younger than 3 years. Structural problems were dominant. Most patients required interventional procedures and antibiotics. PMID:26770223

Information on the clinical features of lung abscess, which is uncommon in children, at hospitalizationis helpful to anticipate the disease course and management. There is no report concerning lung abscess in Korean children. We aimed to identify the clinical characteristics of pediatric lung abscess and compare the difference between primary and secondary abscess groups. The medical records of 11 lung abscess patients (7 males and 4 females) from March 1998 to August 2011 at two university hospitals were retrospectively reviewed. The clinical characteristics, symptoms, underlying disease, laboratory and radiologic findings, microbiological results, and treatments were examined. Six patients had underlying structural-related problems (e.g., skeletal anomalies). No immunologic or hematologic problem was recorded. The mean ages of the primary and secondary groups were 2.4 and 5.3 years, respectively, but the difference was not statistically significant. The mean length of hospital stay was similar in both groups (22.8 days vs. 21.4 days). Immunologic studies were performed in 3 patients; the results were within the normal range. Most patients had prominent leukocytosis. Seven and 4 patients had right and left lung abscess, respectively. Staphylococcus aureus, Streptococcus pneumoniae, and antimycoplasma antibodies were detected in both groups. Two patients with primary lung abscess were administered antibiotics in the absence of other procedures, while 8 underwent interventional procedures, including 5 with secondary abscess. The most common symptoms were fever and cough. All patients in the primary group were younger than 3 years. Structural problems were dominant. Most patients required interventional procedures and antibiotics.

The Natal multimammate mouse (Mastomys natalensis) is the reservoir host of Lassa arenavirus, the etiological agent of Lassa fever in humans. Because there exists no vaccine for human use, rodent control and adjusting human behavior are currently considered to be the only options for Lassa fever control. In order to develop efficient rodent control programs, more information about the host's ecology is needed. In this study, we investigated the spatial behavior of M. natalensis and other small rodents in two capture-mark-recapture and four dyed bait (Rhodamine B) experiments in Lassa fever-endemic villages in Upper Guinea. During the capture-mark-recapture studies, 23% of the recaptured M. natalensis moved between the houses and proximate fields. While M. natalensis was found over the entire study grid (2 ha), other rodent species (Praomys daltoni, Praomys rostratus, Lemniscomys striatus, Mus spp.) were mostly trapped in the surrounding fields. Distances between recapture occasions never exceeded 100 m for all rodent species. During the dyed bait experiments, 11% of M. natalensis and 41% of P. daltoni moved from the fields to houses. We conclude that commensal M. natalensis easily moves between houses and proximate fields in Guinea. We therefore consider occasional domestic rodent elimination to be an unsustainable approach to reduce Lassa virus transmission risk to humans, as M. natalensis is likely to reinvade houses quickly from fields in which rodents are not controlled. A combination of permanent rodent elimination with other control strategies (e.g., make houses rodent proof or attract predators) could be more effective for Lassa fever control, but must be further investigated.

Stage IA non-small-cell lung cancer cases have been recognized as having a low risk of relapse; however, occasionally, relapse may occur. To predict clinical outcome in Stage IA non-small-cell lung cancer patients, we searched for chimeric transcripts that can be used as biomarkers and identified a novel chimeric transcript, RUNX1-GLRX5, comprising RUNX1, a transcription factor, and GLRX5. This chimera was detected in approximately half of the investigated Stage IA non-small-cell lung cancer patients (44/104 cases, 42.3%). Although there was no significant difference in the overall survival rate between RUNX1-GLRX5-positive and -negative cases (P = 0.088), a significantly lower relapse rate was observed in the RUNX1-GLRX5-positive cases (P = 0.039), indicating that this chimera can be used as a biomarker for good prognosis in Stage IA patients. Detection of the RUNX1-GLRX5 chimeric transcript may therefore be useful for the determination of a postoperative treatment plan for Stage IA non-small-cell lung cancer patients. © The Author 2015.

1. Hemolytic streptococcus has been found in 100 per cent of the throats of patients with scarlet fever during the 1st week of the disease. 2. The average length of time that these organisms are present in the throat varies from 10 to 20 days. 3. No morphological or cultural characteristics peculiar to the hemolytic streptococcus from scarlet fever can be demonstrated. 4. Ten immune sera have been prepared from different strains of scarlet fever streptococci and each of the sera agglutinated more than 80 per cent of the strains isolated from scarlatinal throats. On the other hand, scarlatinal streptococci are not agglutinated by immune sera prepared from hemolytic streptococci isolated from other pathological sources. 5. Serum from patients convalescent from scarlet fever agglutinates weakly or not at all the homologous strain of hemolytic streptococcus. 6. The specificity of the agglutination reaction of scarlatinal streptococci is confirmed by absorption experiments. 7. Scarlatinal antistreptococcic serum affords some degree of protection against virulent scarlet fever streptococci but has no protective power against hemolytic streptococci from other diseases. 8. In a small epidemic of scarlet fever a healthy carrier of hemolytic streptococcus was detected; the organism carried was identical in its serological reactions with strains of hemolytic streptococci isolated from active cases of scarlet fever. 9. In a study of a number of contacts with a case of scarlet fever, in only one instance was a scarlatinal type of hemolytic streptococcus recovered from the throat. PMID:19868695

The bacterial endotoxin, lipopolysaccharide (LPS) has been associated with occupational airway diseases with asthma-like symptoms and in acute exacerbations of COPD. The direct and indirect effects of LPS on small airway reactivity have not been fully elucidated. We tested the hypothesis that both in vitro and in vivo LPS treatment would increase contraction and impair relaxation of mouse small airways. Lung slices were prepared from naïve Balb/C mice and cultured in the absence or presence of LPS (10 μg/ml) for up to 48 h for measurement of TNFα levels in conditioned media. Alternatively, mice were challenged with PBS or LPS in vivo once a day for 4 days for preparation of lung slices or for harvest of lungs for Q-PCR analysis of gene expression of pro-inflammatory cytokines and receptors involved in airway contraction. Reactivity of small airways to contractile agonists, methacholine and serotonin, and bronchodilator agents, salbutamol, isoprenaline and rosiglitazone, were assessed using phase-contrast microscopy. In vitro LPS treatment of slices increased TNFα release 6-fold but did not alter contraction or relaxation to any agonists tested. In vivo LPS treatment increased lung gene expression of TNFα, IL-1β and ryanodine receptor isoform 2 more than 5-fold. However there were no changes in reactivity in lung slices from these mice, even when also incubated with LPS ex vivo. Despite evidence of LPS-induced inflammation, neither airway hyperresponsiveness or impaired dilator reactivity were evident. The increase in ryanodine receptor isoform 2, known to regulate calcium signaling in vascular smooth muscle, warrants investigation. Since LPS failed to elicit changes in small airway reactivity in mouse lung slices following in vitro or in vivo treatment, alternative approaches are required to define the potential contribution of this endotoxin to altered small airway reactivity in human lung diseases.

Lung carcinoma is the most prevalent type of cancer in the world, and it is responsible for more deaths than other types of cancer. During diagnosis, a pathologist primarily aims to differentiate small cell carcinoma from non-small cell carcinoma on biopsy and cytology specimens, which is time consuming due to the time required for tissue processing and staining. To speed up the diagnostic process, we investigated the feasibility of using coherent anti-Stokes Raman scattering (CARS) microscopy as a label-free strategy to image lung lesions and differentiate subtypes of lung cancers. Different mouse lung cancer models were developed by injecting human lung cancer cell lines, including adenocarcinoma, squamous cell carcinoma, and small cell carcinoma, into lungs of the nude mice. CARS images were acquired from normal lung tissues and different subtypes of cancer lesions ex vivo using intrinsic contrasts from symmetric CH2 bonds. These images showed good correlation with the hematoxylin and eosin (H&E) stained sections from the same tissue samples with regard to cell size, density, and cell-cell distance. These features are routinely used in diagnosing lung lesions. Our results showed that the CARS technique is capable of providing a visualizable platform to differentiate different kinds of lung cancers using the same pathological features without histological staining and thus has the potential to serve as a more efficient examination tool for diagnostic pathology. In addition, incorporating with suitable fiber-optic probes would render the CARS technique as a promising approach for in vivo diagnosis of lung cancer.

Purpose Lung cancer is the most common cause of cancer mortality in the world. There are limited studies on survival outcomes of lung cancer in developing countries such as India. This study analyzed the outcomes of patients with lung cancer who underwent treatment at Cancer Institute (WIA), Chennai, India, between 2006 and 2015 to determine survival outcomes and identify prognostic factors. Patients and Methods In all, 678 patients with lung cancer underwent treatment. Median age was 58 years, and 91% of patients had non–small-cell lung cancer (NSCLC). Testing for epidermal growth factor receptor mutation was performed in 132 of 347 patients and 61 (46%) were positive. Results Median progression-free survival was 6.9 months and overall survival (OS) was 7.6 months for patients with NSCLC. Median progression-free survival was 6 months and OS was 7.2 months for patients with small-cell lung cancer. On multivariable analysis, the factors found to be significantly associated with inferior OS in NSCLC included nonadenocarcinoma histology, performance status more than 2, and stage. In small-cell lung cancer, younger age and earlier stage at presentation showed significantly better survival. Conclusion Our study highlights the challenges faced in treating lung cancer in India. Although median survival in advanced-stage lung cancer is still poor, strategies such as personalized medicine and use of second-line and maintenance chemotherapy may significantly improve the survival in patients with advanced-stage lung cancer in developing countries.

The ability of beta glucuronidase and a small dose of antigen to modify the anaphylactic reaction of previously sensitized mice has been further investigated. Protamine has an important effect on the immunological behavior of the enzyme. A trial on hay fever patients shows that the results in mice are relevant and that the method can produce significant clinical hyposensitization.

A radiographic method to estimate lung volume and its use in small mammals.

PubMed

Canals, Mauricio; Olivares, Ricardo; Rosenmann, Mario

2005-01-01

In this paper we develop a method to estimate lung volume using chest x-rays of small mammals. We applied this method to assess the lung volume of several rodents. We showed that a good estimator of the lung volume is: V*L = 0.496 x VRX approximately equal to 1/2 x VRX, where VRX is a measurement obtained from the x-ray that represents the volume of a rectangular box containing the lungs and mediastinum organs. The proposed formula may be interpreted as the volume of an ellipsoid formed by both lungs joined at their bases. When that relationship was used to estimate lung volume, values similar to those expected from allometric relationship were found in four rodents. In two others, M. musculus and R. norvegicus, lung volume was similar to reported data, although values were lower than expected.

Lung Cancer Cell Lines as Tools for Biomedical Discovery and Research

Lung cancer cell lines have made a substantial contribution to lung cancer translational research and biomedical discovery. A systematic approach to initiating and characterizing cell lines from small cell and non–small cell lung carcinomas has led to the current collection of more than 200 lung cancer cell lines, a number that exceeds those for other common epithelial cancers combined. The ready availability and widespread dissemination of the lines to investigators worldwide have resulted in more than 9000 citations, including multiple examples of important biomedical discoveries. The high (but not perfect) genomic similarities between lung cancer cell lines and the lung tumor type from which they were derived provide evidence of the relevance of their use. However, major problems including misidentification or cell line contamination remain. Ongoing studies and new approaches are expected to reveal the full potential of the lung cancer cell line panel.

In the 19th century, yellow fever thrived in the tropical, urban trade centers along the American Gulf Coast. Industrializing and populated, New Orleans and Memphis made excellent habitats for the yellow fever-carrying Aedes aegypti mosquitoes and the virulence they imparted on their victims. Known for its jaundice and black, blood-filled vomit, the malady terrorized the region for decades, sometimes claiming tens of thousands of lives during the near annual summertime outbreaks. In response to the failing medical community, a small, pronounced population of sick and healthy laypeople openly criticized the efforts to rid the Gulf region of yellow jack. Utilizing newspapers and cartoons to vocalize their opinions, these critics doubted and mocked the medical community, contributing to the regional and seasonal dilemma yellow fever posed for the American South. These sentient expressions prove to be an early example of patient distrust toward caregivers, a current problem in clinical heath care.

Sheep and goat pox, peste des petits ruminants and Rift Valley fever are important diseases of small ruminant livestock. Sheep and goat pox, along with peste des petits ruminants, are endemic throughout most of Africa, Asia and the Middle East. Whereas Rift Valley fever is endemic in Africa, outbreaks in the Middle East have been reported over the past decade, including the Arabian Peninsula. Saudi Arabia is a major importer of livestock, and understanding the prevalence of these viral infections would be useful for disease control. In this study, sera from sheep and goats were collected from 3 regions in Saudi Arabia. They were evaluated for antibodies specific to sheep and goat pox, peste des petits ruminants and Rift Valley fever by virus neutralization assays. To the best of our knowledge, this is the first study to evaluate the seroprevalence of these viruses in sheep and goats.

Lung cancer is a common disease and the leading cause of cancer-related mortality, with non-small cell lung cancer (NSCLC) accounting for the majority of cases. Following diagnosis of lung cancer, accurate staging is essential to guide clinical management and inform prognosis. Positron emission tomography (PET) in conjunction with computed tomography (CT)—as PET-CT has developed as an important tool in the multi-disciplinary management of lung cancer. This article will review the current evidence for the role of 18F-fluorodeoxyglucose (FDG) PET-CT in NSCLC diagnosis, staging, response assessment and follow up. PMID:29666818

Objective: To analyze the pathogenesis, clinical features, diagnosis and differential diagnosis of primary perivascular epithelioid cell tumor(PEComa). Methods: The clinical features, auxiliary examinations and diagnosis of a case with rapidly progressive pulmonary malignant PEComa were reported and the related literatures were reviewed.The literature review was carried out respectively in Wanfang Data, CNKI and PubMed from Jan. 1975 to Jul. 2015 with "pulmonary malignant perivascular epithelioid cell tumor" and "PEComa" being the search terms. Results: A 50 year-old female patient was admitted to the hospital on September 4, 2014 because of cough and dyspnea for 60 days, hemoptysis for 40 days and fever for 7 days.Chest CT scan showed diffuse small nodules with infiltrative border and multiple pure and mixed ground-glass opacity. Transbronchial lung biopsy (TBLB) was performed and the pathological study confirmed the diagnosis of primary pulmonary malignant PEComa. The patient declined further specific therapy, but followed by rapidly progressive respiratory failure, and died two weeks after the diagnosis. A total of 8 literatures were retrieved from Wanfang Data, CNKI and PubMed and all of them were case reports.There were 3 male and 5 female patients, aging from 50 to 79 years.Radiographically, the previously reported cases presented as round and well-circumscribed masses with or without multiple nodules in both lungs. The symptoms had no specificity. Conclusions: Pulmonary malignant PEComa is a rare disease.It is easily misdiagnosed because of non-specific clinical and imaging manifestations.The final diagnosis depends on pathological biopsy.TBLB is an effective diagnostic method.

Several consultation stations have been set up in an unfinished stone building. My team is made up of a Kenyan physician assistant (called clinical officer), a Kenyan medical student, and me, a US physician assistant student. We are huddled around a small worn-out square table. A middle-aged woman and her two children, ages 2 and 6, approach the table. They have traveled 2 miles to the medical camp. The children, covered in dust, are emaciated with protruding abdomens, dry skin, and congested noses. The clinical officer (CO) conducts a brief interview in Swahili, the Kenyan national language. The mother explains that they have been coughing up thick yellow sputum for a week and have no appetite. They've also had diarrhea for a couple of weeks. I examine the children, who are obviously scared. Hot, moist skin. They are both running a fever. I listen to the lungs: reduced lung sounds. The protruding abdomens are rock hard. I report the findings to the team. The CO turns to the Kenyan medical student and me and quizzes us on differential diagnoses with rationale for each. We come up with malaria, pneumonia, TB, and worm infestation. Due to limited resources, medical diagnosis in Kenya relies heavily on history and physical exam. The CO explains that comorbid conditions are probable. Luckily, we have malaria-testing kits at the camp. They test negative for malaria. We decide to treat them for pneumonia. We also offer them a free hot meal, toothbrushes, T-shirts, coloring paper, and crayons. The children manage to smile. The mother is so grateful, she cries.

Computerised lung sound monitoring to assess effectiveness of chest physiotherapy and secretion removal: a feasibility study.

To explore the feasibility of computerised lung sound monitoring to evaluate secretion removal in intubated and mechanically ventilated adult patients. Before and after observational investigation. Intensive care unit. Fifteen intubated and mechanically ventilated adult patients receiving chest physiotherapy. Chest physiotherapy included combinations of standard closed airway suctioning, saline lavage, postural drainage, chest wall vibrations, manual-assisted cough and/or lung hyperinflation, dependent upon clinical indications. Lung sound amplitude at peak inspiration was assessed using computerised lung sound monitoring. Measurements were performed immediately before and after chest physiotherapy. Data are reported as mean [standard deviation (SD)], mean difference and 95% confidence intervals (CI). Significance testing was not performed due to the small sample size and the exploratory nature of the study. Fifteen patients were included in the study [11 males, four females, mean age 65 (SD 14) years]. The mean total lung sound amplitude at peak inspiration decreased two-fold from 38 (SD 59) units before treatment to 17 (SD 19) units after treatment (mean difference 22, 95% CI of difference -3 to 46). The mean total lung sound amplitude from the lungs of patients with a large amount of secretions (n=9) was over four times 'louder' than the lungs of patients with a moderate or small amount of secretions (n=6) [56 (SD 72) units vs 12 (13) units, respectively; mean difference -44, 95% CI of difference -100 to 11]. The mean total lung sound amplitude decreased in the group of 'loud' right and left lungs (n=15) from 37 (SD 36) units before treatment to 15 (SD 13) units after treatment (mean difference 22, 95% CI of difference 6 to 38). Computerised lung sound monitoring in this small group of patients demonstrated a two-fold decrease in lung sound amplitude following chest physiotherapy. Subgroup analysis also demonstrated decreasing trends in lung sound amplitude in the group of 'loud' lungs following chest physiotherapy. Due to the small sample size and large SDs with high variability in the lung sound amplitude measurements, significance testing was not reported. Further investigation is needed in a larger sample of patients with more accurate measurement of sputum wet weight in order to distinguish between secretion-related effects and changes due to other factors such as airflow rate and pattern.

Small cell lung carcinoma (SCLC) is a neuroendocrine subtype of lung cancer that affects more than 200,000 people worldwide every year with a very high mortality rate. Here, we used a mouse genetics approach to characterize the cell of origin for SCLC; in this mouse model, tumors are initiated by the deletion of the Rb and p53 tumor suppressor genes in the lung epithelium of adult mice. We found that mouse SCLCs often arise in the lung epithelium, where neuroendocrine cells are located, and that the majority of early lesions were composed of proliferating neuroendocrine cells. In addition, mice in which Rb and p53 are deleted in a variety of non-neuroendocrine lung epithelial cells did not develop SCLC. These data indicate that SCLC likely arises from neuroendocrine cells in the lung. PMID:21822053

Improved understanding of molecular drivers of carcinogenesis has led to significant progress in the management of lung cancer. Patients with non-small-cell lung cancer (NSCLC) with anaplastic lymphoma kinase (ALK) gene rearrangements constitute about 4%–5% of all NSCLC patients. ALK+ NSCLC cells respond well to small molecule ALK inhibitors such as crizotinib; however, resistance invariably develops after several months of treatment. There are now several newer ALK inhibitors, with the next generation of agents targeting resistance mutations. In this review, we will discuss the prevalence and clinical characteristics of ALK+ lung cancer, current treatment options, and future directions in the management of this subset of NSCLC patients.

Bevacizumab is a monoclonal antibody targeting the vascular endothelial growth factor receptor and a key drug for advanced non-small cell lung cancer. There are few reports describing bevacizumab-induced chronic interstitial pneumonia. A 62-year-old man with advanced non-small cell lung cancer was admitted to our hospital with dyspnea. He previously received four courses of carboplatin plus paclitaxel with bevacizumab combination therapy and thereafter received four courses of maintenance bevacizumab monotherapy. A chest-computed tomography scan on admission revealed diffuse ground glass opacity. He had not received any other drugs and did not have pneumonia. Thus, he was diagnosed with bevacizumab-induced chronic interstitial pneumonia and was treated with a high dose of corticosteroids. After steroid treatment, his dyspnea and radiological findings improved. This case report is the first description of bevacizumab-induced chronic interstitial pneumonia during maintenance therapy in a patient with non-small cell lung cancer.

The purpose of this study was to evaluate the therapeutic efficacy of Re-188-RC-160 in experimental models of human small cell lung carcinomas which mimic the clinical presentation. In the experimental model, cells from the human small cell lung carcinoma cell line NCI-H69 cells were inoculated into the thoracic cavity of athymic mice and rats. Subsequently, the biodistribution of Re-188-RC-160 after injection into the pleural cavity, a radiolabeled somatostatin analogue, was monitored as was the effect on the subsequent growth of tumors. The results presented here, and which are a part of a larger series of studies, suggest that Re-188-RC-160 canmore » be effectively used in this animal model to restrict the growth of small cell lung carcinoma in the thoracic cavity.« less

Understanding the drug development pathway is critical for streamlining the development of effective cancer treatments. The objective of the current study was to delineate the drug development timeline and attrition rate of different drug classes for common cancer disease sites. Drugs entering clinical trials for breast, colorectal, and non-small cell lung cancer were identified using a pharmaceutical business intelligence database. Data regarding drug characteristics, clinical trials, and approval dates were obtained from the database, clinical trial registries, PubMed, and regulatory Web sites. A total of 411 drugs met the inclusion criteria for breast cancer, 246 drugs met the inclusion criteria for colorectal cancer, and 315 drugs met the inclusion criteria for non-small cell lung cancer. Attrition rates were 83.9% for breast cancer, 87.0% for colorectal cancer, and 92.0% for non-small cell lung cancer drugs. In the case of non-small cell lung cancer, there was a trend toward higher attrition rates for targeted monoclonal antibodies compared with other agents. No tumor site-specific differences were noted with regard to cytotoxic chemotherapy, immunomodulatory, or small molecule kinase inhibitor drugs. Drugs classified as "others" in breast cancer had lower attrition rates, primarily due to the higher success of hormonal medications. Mean drug development times were 8.9 years for breast cancer, 6.7 years for colorectal cancer, and 6.6 years for non-small cell lung cancer. Overall oncologic drug attrition rates remain high, and drugs are more likely to fail in later-stage clinical trials. The refinement of early-phase trial design may permit the selection of drugs that are more likely to succeed in the phase 3 setting.

Novel approaches are needed for discovery of targeted therapies for non-small-cell lung cancer (NSCLC) that are specific to certain patients. Whole genome RNAi screening of lung cancer cell lines provides an ideal source for determining candidate drug targets. Unsupervised learning algorithms uncovered patterns of differential vulnerability across lung cancer cell lines to loss of functionally related genes. Such genetic vulnerabilities represent candidate targets for therapy and are found to be involved in splicing, translation and protein folding.

Change from lung adenocarcinoma to small cell lung cancer as a mechanism of resistance to afatinib.

We report the case of a patient affected by advanced EGFR mutation-positive lung who experienced resistance to therapy during treatment with Afatinib through the occurrence of a switch of tumor histotype to small cell lung cancer (SCLC) with features of a G3 neuroendocrine carcinoma. Unexpectedly, the switch to SCLC histotype occurred in the only site not responsive to afatinib and subsequently the most responsive to chemotherapy. Our case shows that occurrence of switch to SCLC is a possible mechanism of resistance during treatment with Afatinib.

Severe respiratory failure as a presenting feature of an interstitial lung disease associated with anti-synthetase syndrome (ASS).

2016-07-01

Anti-synthetase syndrome (ASS) is defined as a heterogeneous connective tissue disorder characterized by the association of an interstitial lung disease (ILD) with or without inflammatory myositis with the presence of anti-aminoacyl-tRNA-synthetase antibodies. ILD is one of the major extra-muscular manifestations of polymyositis and dermatomyositis. We report a case of a patient with dyspnea, cough, and intermittent fever as well as ILD associated ASS in the absence of muscular involvement. This patient was admitted to the emergency department with severe respiratory failure requiring non-invasive ventilation. Our patient's case demonstrates that the diagnosis of ASS may not be obvious. However, its diagnosis leads to appropriate and potentially life-saving treatment. Copyright © 2016 The Japanese Respiratory Society. Published by Elsevier B.V. All rights reserved.

Observations on the epidemiology of Rift Valley fever in Kenya.

PubMed

Davies, F G

1975-10-01

The epizootic range of Rift Valley fever in Kenya is defined from the results of virus isolations during epizootics, and form an extensive serological survey of cattle which were exposed during an epizootic. A study of the sera from a wide range of wild bovidae sampled immediately after the epizootic, showed that they did not act as reservoir or amplifying hosts for RVF. Virus isolation attempts from a variety of rodents proved negative. Rift Valley fever did not persist between epizootics by producing symptomless abortions in cattle in areas within its epizootic range. A sentinel herd sampled annually after an epizootic in 1968 revealed not one single seroconversion from 1969 to 1974. Certain forest and forest edge situations were postulated as enzootic for Rift Valley fever, and a small percentage of seroconversions were detected in cattle in these areas, born four years after the last epizootic. This has been the only evidence for the persistence of the virus in Kenya since 1968, and may be a part of the interepizootic maintenance cycle for Rift Valley fever in Kenya, which otherwise remains unknown.

Yellow fever vaccine provides long-lasting immunity. Rare serious adverse events after vaccination include neurologic or viscerotropic syndromes or anaphylaxis. We conducted a systematic review of adverse events associated with yellow fever vaccination in vulnerable populations. Nine electronic bibliographic databases and reference lists of included articles were searched. Electronic databases identified 2,415 abstracts for review, and 32 abstracts were included in this review. We identified nine studies of adverse events in infants and children, eight studies of adverse events in pregnant women, nine studies of adverse events in human immunodeficiency virus-positive patients, five studies of adverse events in persons 60 years and older, and one study of adverse events in individuals taking immunosuppressive medications. Two case studies of maternal-neonate transmission resulted in serious adverse events, and the five passive surveillance databases identified very small numbers of cases of yellow fever vaccine-associated viscerotropic disease, yellow fever vaccine-associated neurotropic disease, and anaphylaxis in persons ≥ 60 years. No other serious adverse events were identified in the other studies of vulnerable groups.

The Contribution of Small Airway Obstruction to the Pathogenesis of Chronic Obstructive Pulmonary Disease.

PubMed

Hogg, James C; Paré, Peter D; Hackett, Tillie-Louise

2017-04-01

The hypothesis that the small conducting airways were the major site of obstruction to airflow in normal lungs was introduced by Rohrer in 1915 and prevailed until Weibel introduced a quantitative method of studying lung anatomy in 1963. Green repeated Rohrer's calculations using Weibels new data in 1965 and found that the smaller conducting airways offered very little resistance to airflow. This conflict was resolved by seminal experiments conducted by Macklem and Mead in 1967, which confirmed that a small proportion of the total lower airways resistance is attributable to small airways <2 mm in diameter. Shortly thereafter, Hogg, Macklem, and Thurlbeck used this technique to show that small airways become the major site of obstruction in lungs affected by emphysema. These and other observations led Mead to write a seminal editorial in 1970 that postulated the small airways are a silent zone within normal lungs where disease can accumulate over many years without being noticed. This review provides a progress report since the 1970s on methods for detecting chronic obstructive pulmonary disease, the structural nature of small airways' disease, and the cellular and molecular mechanisms that are thought to underlie its pathogenesis.

Non-small cell lung cancer is the most common type of lung cancer. Both environmental and genetic risk factors contribute to lung carcinogenesis. We conducted a genome-wide interaction analysis between single nucleotide polymorphisms (SNPs) and smoking status (never- versus ever-smokers) in a European-descent population. We adopted a two-step analysis strategy in the discovery stage: we first conducted a case-only interaction analysis to assess the relationship between SNPs and smoking behavior using 13336 non-small cell lung cancer cases. Candidate SNPs with P-value <0.001 were further analyzed using a standard case-control interaction analysis including 13970 controls. The significant SNPs with P-value <3.5 × 10-5 (correcting for multiple tests) from the case-control analysis in the discovery stage were further validated using an independent replication dataset comprising 5377 controls and 3054 non-small cell lung cancer cases. We further stratified the analysis by histological subtypes. Two novel SNPs, rs6441286 and rs17723637, were identified for overall lung cancer risk. The interaction odds ratio and meta-analysis P-value for these two SNPs were 1.24 with 6.96 × 10-7 and 1.37 with 3.49 × 10-7, respectively. In addition, interaction of smoking with rs4751674 was identified in squamous cell lung carcinoma with an odds ratio of 0.58 and P-value of 8.12 × 10-7. This study is by far the largest genome-wide SNP-smoking interaction analysis reported for lung cancer. The three identified novel SNPs provide potential candidate biomarkers for lung cancer risk screening and intervention. The results from our study reinforce that gene-smoking interactions play important roles in the etiology of lung cancer and account for part of the missing heritability of this disease.

Description of the treatment technique of stereotactic lung radiotherapy on Novalis Tx ® and prospective study of the first 100 pulmonary nodules treated at centre Jean-Perrin (France). From October 2012 to December 2015, 100 inoperable pulmonary nodules (62 stage I non-small-cell lung cancer and 38 metastases) of 90 patients with a mean age of 68.2 years (range: 46-89 years) were prospectively treated with dynamic arctherapy on Novalis Tx ® . Mean gross tumour and planning target volumes were respectively 6.9 cm 3 (range: 0.2-31.4 cm 3 ) and 38.7 cm 3 (range: 1.7-131 cm 3 ), which correspond to diameters equal to 2.3cm and 4.2cm. Prescribed doses to the 80% isodose line were 54Gy in three fractions for peripheral non-small-cell lung cancer, 50Gy in five fractions for central non-small-cell lung cancer and 45Gy in three fractions for lung metastases. Clinical and radiological follow-up was done every three months with RECIST criteria for efficacy and NCI-CTCAE v4 scale for toxicity. Median follow-up was 12.5 months. Complete response was observed in 23.8% of cases. Local control rates were 100% and 90.7% respectively at 12 and 24 months, with 96% at 24 months for stage I non-small-cell lung cancer. Overall survival rates of patients with stage I non-small-cell lung cancer were 77.4% and 73.5% at 12 and 24 months (median overall survival was 32 months). Diffusing capacity of the lungs for carbon monoxide corrected for alveolar volume below 40% was significantly associated to a poor prognostic factor on univariate analysis (P=0.00013). At least three deaths were due to an acute respiratory failure, which correspond to about 4.8% of grade 5 radiation pneumonitis. Overall survival rate for metastatic patients were 95.2% and 59.5% respectively at 12 and 24 months (median overall survival was 25 months); 23.3% of grade 2 or less radiation pneumonitis, 7.8% of grade 2 or less radiation dermatitis, 2.2% of asymptomatic ribs fracture and 3.3% of chest pains were observed. Stereotactic lung radiotherapy is an effective treatment for inoperable stage I non-small-cell lung cancer and lung oligometastases of well informed and selected patients. Initial respiratory state, and especially the diffusing capacity of the lungs for carbon monoxide corrected for alveolar volume, seems to be important for tolerance.

Many welders have experienced bronchitis, metal fume fever, lung function changes, and an increase in the incidence of lung infection. Questions remain regarding the possible mechanisms associated with the potential pulmonary effects of welding fume exposure. The objective was to assess the early effects of stainless steel (SS) welding fume inhalation on lung injury, inflammation, and defense responses. Male Sprague-Dawley rats were exposed to gas metal arc-SS welding fume at a concentration of 15 or 40 mg/m(3) x 3 h/day for 1, 3, or 10 days. The control group was exposed to filtered air. To assess lung defense responses, some animals were intratracheally inoculated with 5x10(4) Listeria monocytogenes 1 day after the last exposure. Welding particles were collected during exposure, and elemental composition and particle size were determined. At 1, 4, 6, 11, 14, and 30 days after the final exposure, parameters of lung injury (lactate dehydrogenase and albumin) and inflammation (PMN influx) were measured in the bronchoalveolar lavage fluid. In addition, particle-induced effects on pulmonary clearance of bacteria and macrophage function were assessed. SS particles were composed of Fe, Cr, Mn, and Ni. Particle size distribution analysis indicated the mass median aerodynamic diameter of the generated fume to be 0.255 microm. Parameters of lung injury were significantly elevated at all time points post-exposure compared to controls except for 30 days. Interestingly, no significant difference in lung PMNs was observed between the SS and control groups at 1, 4, and 6 days post-exposure. After 6 days post-exposure, a dramatic increase in lung PMNs was observed in the SS group compared to air controls. Lung bacteria clearance and macrophage function were reduced and immune and inflammatory cytokines were altered in the SS group. In summary, short-term exposure of rats to SS welding fume caused significant lung damage and suppressed lung defense responses to bacterial infection, but had a delayed effect on pulmonary inflammation. Additional chronic inhalation studies are needed to further examine the lung effects associated with SS welding fume exposure.

Xu, Ziyue; Mansoor, Awais; Mollura, Daniel J.

Purpose: To develop an automated pulmonary image analysis framework for infectious lung diseases in small animal models. Methods: The authors describe a novel pathological lung and airway segmentation method for small animals. The proposed framework includes identification of abnormal imaging patterns pertaining to infectious lung diseases. First, the authors’ system estimates an expected lung volume by utilizing a regression function between total lung capacity and approximated rib cage volume. A significant difference between the expected lung volume and the initial lung segmentation indicates the presence of severe pathology, and invokes a machine learning based abnormal imaging pattern detection system next.more » The final stage of the proposed framework is the automatic extraction of airway tree for which new affinity relationships within the fuzzy connectedness image segmentation framework are proposed by combining Hessian and gray-scale morphological reconstruction filters. Results: 133 CT scans were collected from four different studies encompassing a wide spectrum of pulmonary abnormalities pertaining to two commonly used small animal models (ferret and rabbit). Sensitivity and specificity were greater than 90% for pathological lung segmentation (average dice similarity coefficient > 0.9). While qualitative visual assessments of airway tree extraction were performed by the participating expert radiologists, for quantitative evaluation the authors validated the proposed airway extraction method by using publicly available EXACT’09 data set. Conclusions: The authors developed a comprehensive computer-aided pulmonary image analysis framework for preclinical research applications. The proposed framework consists of automatic pathological lung segmentation and accurate airway tree extraction. The framework has high sensitivity and specificity; therefore, it can contribute advances in preclinical research in pulmonary diseases.« less

Ebolavirus and Marburgvirus are members of the filovirus family and induce a fatal hemorrhagic disease in humans and nonhuman primates with 90% case fatality. To develop a small nonhuman primate model for filovirus disease, common marmosets (Callithrix jacchus) were intramuscularly inoculated with wild type Marburgvirus Musoke or Ebolavirus Zaire. The infection resulted in a systemic fatal disease with clinical and morphological features closely resembling human infection. Animals experienced weight loss, fever, high virus titers in tissue, thrombocytopenia, neutrophilia, high liver transaminases and phosphatases and disseminated intravascular coagulation. Evidence of a severe disseminated viral infection characterized principally by multifocal to coalescing hepatic necrosis was seen in EBOV animals. MARV-infected animals displayed only moderate fibrin deposition in the spleen. Lymphoid necrosis and lymphocytic depletion observed in spleen. These findings provide support for the use of the common marmoset as a small nonhuman primate model for filovirus induced hemorrhagic fever. Copyright © 2011 Elsevier Inc. All rights reserved.

Since it has been recognized as a separate disease during the Korean war, hemorrhagic fever with renal syndrome (HFRS) has often been discovered among the members of different armies in various countries, military personnel being the highest risk group for the disease. In the period from March to May 1999 we treated 6 soldiers coming from the military formation stationed at Kosovo and Metohia. The reaction of indirect hemagglutination test proved the presence of antibodies against Hantavira in each of them. They were infected during the stay in a dugout in the area with great population of field rodents. Only one patient was slightly ill, on the admission to the hospital. The others had severe clinical and laboratory findings: several days lasting fever, strong abdominal pain, as well as the pain in the loins, dyspeptical discomfort, manifold increased blood urea nitrogen and serum creatinine values, thrombocytopenia, etc. Oliguria occurred in 4 patients. Hemorrhagic manifestations were slight (epistaxis, petechial rash, conjunctival injection), or absent. Because of the aggravation of the acute renal failure, hemodialysis was performed in 3 patients, while other 3 underwent conservative treatment. Two of the patients had severe anemia because of which transfusions of erythrocytes and plasma were performed. Complications occurred in 2 patients (convulsive crises and lung infections). All patients recovered completely.

Q fever, a commonly reported zoonosis worldwide, is caused by infection with Coxiella burnetii, an obligate intracellular bacterium. The infection is often asymptomatic in ruminants, but it can lead to reproductive disorders with bacterial shedding into the environment. Between 2011 and 2013, a study was undertaken in small ruminant flocks in different regions of Algeria. A total of 35 flocks were visited and 227 sera and 267 genital swabs were collected from females after abortions or the lambing period to investigate Q fever infection. Indirect ELISA was used to detect specific antibodies against C. burnetii and real-time PCR for detecting bacterial DNA. Our survey indicated that 58% (95% CI=40-76%) of flocks had at least one positive animal (17 seropositive flocks) and individual seroprevalence was estimated at 14.1% (95% CI=11.8-16.4%) (32 seropositive animals). Bacterial excretion was observed in 21 flocks (60%), and 57 females showed evidence of C. burnetii shedding (21.3%). These results suggest that C. burnetii distribution is high at the flock level and that seropositive and infected (shedder) animals can be found all over the country. Further studies are needed in other regions and on different animal species to better understand the distribution and incidence of Q fever, as well as human exposure, and to develop an adequate prophylaxis program.

Background. This study examines prevalence of respiratory conditions in New Orleans-area restoration workers after Hurricane Katrina. Methods. Between 2007 and 2010, spirometry and respiratory health and occupational questionnaire were administered to 791 New Orleans-area adults who mostly worked in the building construction and maintenance trades or custodial services. The associations between restoration work hours and lung function and prevalence of respiratory symptoms were examined by multiple linear regression, χ 2, or multiple logistic regression. Results. 74% of participants performed post-Katrina restoration work (median time: 620 hours). Symptoms reported include episodes of transient fever/cough (29%), sinus symptoms (48%), pneumonia (3.7%), and new onset asthma (4.5%). Prevalence rate ratios for post-Katrina sinus symptoms (PRR = 1.3; CI: 1.1, 1.7) and fever and cough (PRR = 1.7; CI: 1.3, 2.4) were significantly elevated overall for those who did restoration work and prevalence increased with restoration work hours. Prevalence rate ratios with restoration work were also elevated for new onset asthma (PRR = 2.2; CI: 0.8, 6.2) and pneumonia (PRR = 1.3; CI: 0.5, 3.2) but were not statistically significant. Overall, lung function was slightly depressed but was not significantly different between those with and without restoration work exposure. Conclusions. Post-Katrina restoration work is associated with moderate adverse effects on respiratory health, including sinusitis and toxic pneumonitis. PMID:23365586

Bronchiolitis obliterans organizing pneumonia (BOOP) is a distinct pattern of reaction of the lung to injury. It may be idiopathic or secondary to a variety of injuries. The term cryptogenic organizing pneumonia (COP) is used for patients with idiopathic BOOP. In this study we describe clinical and radiologic features of patients with BOOP. The medical records of 33 patients with diagnosis of BOOP on surgical lung biopsy over a 10-year time period were reviewed retrospectively. We obtained data on clinical and radiologic manifestations, etiology, and outcome of these patients. Dyspnea was the most common symptom, followed by dry cough and fever. Crackles was the most common physical finding. Mean age at diagnosis of BOOP was 59 years, and 42% were females. The main radiologic manifestation was bilateral patchy consolidation. Most patients had favorable prognosis; however, 17% did not respond to treatment. Female sex was more common in COP than in secondary BOOP (P = .004). Patients with COP had longer symptom duration before the diagnosis than secondary BOOP (P = .01). Patients with secondary BOOP reported fever more frequently, compared to COP (P = .005). Pleural effusion was present in 60% of patients with secondary BOOP, whereas none of the patients with COP had effusion (P = .004). COP and secondary BOOP have diverse clinical and radiologic manifestations. Patients with secondary BOOP are more symptomatic. Both COP and secondary BOOP patients have good prognosis, and most respond to treatment with corticosteroids or by discontinuing the injurious drug.

An 8-year-old girl who had experienced intermittent cough and fever over a 3 year period, was admitted after experiencing a recurrence for one month. One year ago the patient experienced a recurrent oral mucosal ulcer. Physical examination showed vitiligo in the skin of the upper right back. Routine blood tests and immune function tests performed in other hospitals had shown normal results. Multiple lung CT scans showed pulmonary infection. The patient had recurrent fever and cough and persistent presence of some lesions after anti-infective therapy. The antitubercular therapy was ineffective. Routine blood tests after admission showed agranulocytosis. Gene detection was performed and she was diagnosed with dyskeratosis congenita caused by homozygous mutation in RTEL1. Patients with dyskeratosis congenita with RTEL1 gene mutation tend to develop pulmonary complications. Since RTEL1 gene sequence is highly variable with many mutation sites and patterns and can be inherited via autosomal dominant or recessive inheritance, this disease often has various clinical manifestations, which may lead to missed diagnosis or misdiagnosis. For children with unexplained recurrent pulmonary infection, examinations of the oral cavity, skin, and nails and toes should be taken and routine blood tests should be performed to exclude dyskeratosis congenita. There are no specific therapies for dyskeratosis congenita at present, and when bone marrow failure and pulmonary failure occur, hematopoietic stem cell transplantation and lung transplantation are the only therapies. Androgen and its derivatives are effective in some patients. Drugs targeting the telomere may be promising for patients with dyskeratosis congenita.

Lung adenoid cystic carcinoma is a kind of rare lung cancer. Diagnosis and treatment is not enough understandable for them. We collected and analyzed 4 cases of lung adenoid cystic carcinoma for broadening the sight of this disease. Retrospectively analysed the 4 cases we collected from Hunan Cancer Hospital Between January 2012 and December 2016. We depicted the pathology, immunohistochemical, epidermal growth factor receptor (EGFR) mutation and anaplastic lymphoma kinase (ALK) arrangement in these cases. And the methods of the diagnosis and treatment were analyzed. Lung adenoid cystic carcinoma is usually located in the airway, EGFR mutation and ALK arrangement is rare in this disease. Generally the metastasis of the lung cancer occurred in the advanced stage. The prognosis is good if the mass could be resected completely. Diagnosis of the lung adenoid cystic carcinoma depends on pathological experiments, surgery is the main treatment in the early stage, radiotherapy and chemotherapy is an advisable therapy in the advanced stage. And the prognosis of this kind of lung cancer is better than small cell lung cancer and non-small cell lung cancer.

Monodisperse, Uniformly-Shaped Particles for Controlled Respiratory Vaccine Delivery

NASA Astrophysics Data System (ADS)

Fromen, Catherine Ann

The majority of the world's most infectious diseases occur at the air-tissue interface called the mucosa, including HIV/AIDS, tuberculosis, measles, and bacterial or viral gut and respiratory infections. Despite this, vaccines have generally been developed for the systemic immune system and fail to provide protection at the mucosal site. Vaccine delivery directly to the lung mucosa could provide superior lung protection for many infectious diseases, such as TB or influenza, as well as systemic and therapeutic vaccines for diseases such as Dengue fever, asthma, or cancer. Specifically, precision engineered biomaterials are believed to offer tremendous opportunities for a new generation of vaccines. The goal of this approach is to leverage naturally occurring processes of the immune system to produce memory responses capable of rapidly destroy virulent pathogens without harmful exposure. Considerable knowledge of biomaterial properties and their interaction with the immune system of the lung is required for successful translation. The overall goal of this work was to fabricate and characterize nano- and microparticles using the Particle Replication In Non-wetting Templates (PRINT) fabrication technique and optimize them as pulmonary vaccine carriers.

Summary Background: Exogenous lipoid pneumonia is an uncommon condition caused by inhalation or aspiration of a fatty substance. It usually presents as chronic respiratory illness mimicking interstitial lung diseases. Acute exogenous lipoid pneumonia is uncommon and typically is caused by an episode of aspiration of a large quantity of a petroleum-based product. Radiological findings vary and may imitate many other diseases. Case Report: We present a rare case of acute exogenous lipoid pneumonia in a fire-eater who aspirated liquid paraffin during his flame-blowing show (fire-eater’s lung). He was admitted to the hospital with productive cough, fever, hemoptysis, chest pain and dyspnea. Diagnosis was made on the basis of history of exposure to fatty substance, characteristic findings in CT examination and presence of lipid-laden macrophages in bronchoalveolar lavage fluid. Conclusions: Acute exogenous lipoid pneumonia is a very rare disease that typically occurs in fire-eaters and is called a fire-eater’s lung. The diagnosis is made on the basis of typical history and radiological, as well as histopathological findings. PMID:23269939

Among patients with respiratory insufficiency awaiting lung transplantation, small adult patients have a lower opportunity of receiving size-matched pulmonary grafts, because of the shortage of donors, particularly those of small size. Reducing the size of an oversized graft is one of the methods to increase the donor pool; similarly, ex vivo lung perfusion is an emerging technique aimed toward the same purpose. We describe how we combined the 2 techniques (lobar transplantation plus contralateral nonanatomic graft reduction during ex vivo lung perfusion) to overcome graft shortage in a clinical case. For the 1st time, this case report demonstrates that surgical manipulation during ex vivo lung perfusion does not affect the functional improvement in a lung previously judged to be not suitable for transplantation. The 6-month follow-up results are similar to those of standard bilateral lung transplantation. Copyright © 2014 Elsevier Inc. All rights reserved.

The molecular investigation of lung cancer has opened up an advanced area for the diagnosis and therapeutic management of lung cancer patients. Gene alterations in cancer initiation and progression provide not only information on molecular changes in lung cancer but also opportunities in advanced therapeutic regime by personalized targeted therapy. EGFR mutations and ALK rearrangement are important predictive biomarkers for the efficiency of tyrosine kinase inhibitor treatment in lung cancer patients. Moreover, epigenetic aberration and microRNA dysregulation are recent advances in the early detection and monitoring of lung cancer. Although a wide range of molecular tests are available, standardization and validation of assay protocols are essential for the quality of the test outcome. In this review, current and new advancements of molecular biomarkers for non-small-cell lung cancer will be discussed. Recommendations on future development of molecular diagnostic services will also be explored.

Small cell lung cancer transformation from EGFR-mutated lung adenocarcinoma: A case report and literatures review.

Epithelial growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) have markedly improved the response of non-small cell lung cancer (NSCLC) with EGFR-mutant patients. However, these patients inevitably come cross acquired resistance to EGFR-TKIs. The transformation of lung adenocarcinoma to small cell lung cancer (SCLC) following treatment with EGFR-TKIs is rare, which leads to resistance to EGFR-TKIs. The present case concerns a case of a 38-year-old man presenting with cough and dyspnea. Radical resection was performed and confirmed an EGFR exon 21 L858R lung adenocarcinoma. However, the patient suffered pleural metastasis after successful treatment with surgery and adjuvant treatment. So, erlotinib was administered with 18 months. Because of enlarged pleural nodule, repeat biopsy identified an SCLC and chemotherapy was started. However, despite the brief success of chemotherapy, our patient suffered brain metastasis. Our case emaphsizes both the profile of transformation from NSCLC to SCLC and the importance of repeat biopsy dealing with drug resistance. We also summarize the clinical characteristics, mechanisms, predictors of SCLC transformation, treatment after transformation and other types of transformation to SCLC.

Retinoic acid-inducible gene-I (RIG-I)-like receptors (RLRs) are pattern-recognition receptors that recognize pathogen-associated molecular patterns and induce antiviral immune responses. Recent studies have demonstrated that RLR activation induces antitumor immunity and cytotoxicity against different types of cancer, including lung cancer. However a previous report has demonstrated that ionizing radiation exerts a limited effect on RLR in human monocytic cell-derived macrophages, suggesting that RLR agonists may be used as effective immunostimulants during radiation therapy. However, it is unclear whether ionizing radiation affects the cytotoxicity of RLR agonists against cancer cells. Therefore, in the present study the effects of cotreatment with ionizing radiation and RLR agonists on cytotoxicity against human non-small cell lung cancer cells A549 and H1299 was investigated. Treatment with RLR agonist poly(I:C)/LyoVec™ [poly(I:C)] exerted cytotoxic effects against human non-small cell lung cancer. The cytotoxic effects of poly(I:C) were enhanced by cotreatment with ionizing radiation, and poly(I:C) pretreatment resulted in the radiosensitization of non-small cell lung cancer. Furthermore, cotreatment of A549 and H1299 cells with poly(I:C) and ionizing radiation effectively induced apoptosis in a caspase-dependent manner compared with treatment with poly(I:C) or ionizing radiation alone. These results indicate that RLR agonists and ionizing radiation cotreatment effectively exert cytotoxic effects against human non-small cell lung cancer through caspase-mediated apoptosis.

Current paradigms hold that lung carcinomas arise from pleuripotent stem cells capable of differentiation into one or several histological types. These paradigms suggest lung tumor cell ontogeny is determined by consequences of gene expression that recapitulate events important in embryonic lung development. Using oligonucleotide microarrays, we acquired gene profiles from 32 microdissected non-small-cell lung tumors. We determined the 100 top-ranked marker genes for adenocarcinoma, squamous cell, large cell, and carcinoid using nearest neighbor analysis. Results were validated by immunostaining for 11 selected proteins using a tissue microarray representing 80 tumors. Gene expression data of lung development were accessed from a publicly available dataset generated with the murine Mu11k genome microarray. Self-organized mapping identified two temporally distinct clusters of murine orthologues. Supervised clustering of lung development data showed large-cell carcinoma gene orthologues were in a cluster expressed in pseudoglandular and canalicular stages whereas adenocarcinoma homologues were predominantly in a cluster expressed later in the terminal sac and alveolar stages of murine lung development. Representative large-cell genes (E2F3, MYBL2, HDAC2, CDK4, PCNA) are expressed in the nucleus and are associated with cell cycle and proliferation. In contrast, adenocarcinoma genes are associated with lung-specific transcription pathways (SFTPB, TTF-1), cell adhesion, and signal transduction. In sum, non-small-cell lung tumors histology gene profiles suggest mechanisms relevant to ontogeny and clinical course. Adenocarcinoma genes are associated with differentiation and glandular formation whereas large-cell genes are associated with proliferation and differentiation arrest. The identification of developmentally regulated pathways active in tumorigenesis provides insights into lung carcinogenesis and suggests early steps may differ according to the eventual tumor morphology.

Pyrogen fever and prostaglandin-like activity in cerebrospinal fluid

1. In the unanaesthetized cat, rectal temperature was recorded and c.s.f. was collected from a Collison cannula implanted into the third ventricle with its opening lying in close proximity to the anterior hypothalamus. Samples of c.s.f. were collected from the same cat, during normal temperature, during fever produced by Shigella dysenteriae injected into the third ventricle and during the fall in temperature which occurred when the antipyretic paracetamol was injected intraperitoneally during the pyrogen fever. 2. The samples of c.s.f., when tested on the rat stomach fundus preparation, caused contractions which were not due, or at most to a small degree only, to 5-hydroxytryptamine, as they were resistant to BOL. They were therefore probably due to a prostaglandin-like substance. 3. When assayed against PGE1, the activity of c.s.f. collected from cats when their body temperature was normal corresponded to between 1·3 and 10 ng/ml. The values, whether low or high, rose over 2·5-4 times to between 4 and 35 ng/ml. in c.s.f. collected during pyrogen fever; they were again low, between 1·5 and 6 ng/ml., in samples collected when the fever had been brought down by paracetamol, but rose again with the return of fever. 4. The results provide direct evidence for the theory that fever produced by pyrogens results from their ability to increase synthesis and release of prostaglandins, and that antipyretics bring down the fever because they inhibit the increased synthesis.

Airway compliance is a key factor in understanding lung mechanics and is used as a clinical diagnostic index. Understanding such mechanics in small airways physiologically and clinically is critical. We have determined the "morphometric change" and "localized compliance" of small airways under "near"-physiological conditions; namely, the airways were embedded in parenchyma without dehydration and fixation. Previously, we developed a two-step method to visualize small airways in detail by staining the lung tissue with a radiopaque solution and then visualizing the tissue with a cone-beam microfocal X-ray computed tomography system (Sera et al. J Biomech 36: 1587-1594, 2003). In this study, we used this technique to analyze changes in diameter and length of the same small airways ( approximately 150 microm ID) and then evaluated the localized compliance as a function of airway generation (Z). For smaller (<300-microm-diameter) airways, diameter was 36% larger at end-tidal inspiration and 89% larger at total lung capacity; length was 18% larger at end-tidal inspiration and 43% larger at total lung capacity than at functional residual capacity. Diameter, especially at smaller airways, did not behave linearly with V(1/3) (where V is volume). With increasing lung pressure, diameter changed dramatically at a particular pressure and length changed approximately linearly during inflation and deflation. Percentage of airway volume for smaller airways did not behave linearly with that of lung volume. Smaller airways were generally more compliant than larger airways with increasing Z and exhibited hysteresis in their diameter behavior. Airways at higher Z deformed at a lower pressure than those at lower Z. These results indicated that smaller airways did not behave homogeneously.

To assess the prevalence of respiratory symptoms and to measure spirometry in a sample of employees of Birmingham International Airport, United Kingdom, to examine whether occupational exposure to aircraft fuel or jet stream exhaust might be associated with respiratory symptoms or abnormalities of lung function. Cross sectional survey by questionnaire and on site measurement of lung function, skin prick tests, and exhaled carbon monoxide concentrations. Occupational exposure was assigned by job title, between group comparison were made by logistic regression analysis. 222/680 full time employees were studied (mean age 38.6 y, 63% male, 28% current smokers, 6% self reported asthma, 19% self reported hay fever). Upper and lower respiratory tract symptoms were common and 51% had one or more positive skin tests. There were no significant differences in lung function tests between exposure groups. Between group comparisons of respiratory symptoms were restricted to male members of the medium and high exposure groups. The adjusted odds ratio (OR) for cough with phlegm and runny nose were found to be significantly associated with high exposure (OR 3.5, 95% confidence interval (95% CI) 1.23 to 9.74 and 2.9, 1.32 to 6.40 respectively) when the measured confounding effects of age and smoking, and in the case of runny nose, self reported hay fever had been taken into account. There was no obvious association between high exposure and the presence of shortness of breath or wheeze, or for the symptoms of watering eyes or stuffy nose. These findings support an association in male airport workers, between high occupational exposures to aviation fuel or jet stream exhaust and excess upper and lower respiratory tract symptoms, in keeping with a respiratory irritant. It is more likely that these effects reflect exposure to exhaust rather than fuel, although the effects of an unmeasured agent cannot be discounted.

Patient: Female, 23 Final Diagnosis: Chronic granulomatous disease Symptoms: Fever • shortness of breath Medication: — Clinical Procedure: Bronchoscopy Specialty: Pulmonology Objective: Unusual clinical course Background: Chronic Granulomatous Disease (CGD) is a rare immunodeficiency disease caused by a genetic defect in the NADPH (nicotinamide adenine dinucleotide phosphate) oxidase enzyme, resulting in increased susceptibility to bacterial and fungal infections. The inheritance can be X-linked or autosomal recessive. Patients usually present with repeated infections early in life. We present an unusual case of a 23-year-old patient diagnosed with CGD. Case Report: A 23-year-old white woman with no previous history of recurrent infections presented with complaints of fever, shortness of breath, and diffuse myalgia. She had been treated twice for similar complaints recently, but without resolution. She was febrile, tachypneic, tachycardic, and hypoxic at presentation. Physical examination revealed diffuse inspiratory rales. Laboratory results showed leukocytosis. Her initial chest X-ray and CT chest showed reticular nodular interstitial lung disease pattern. Despite being on broad-spectrum antibiotics for 5 days, she continued to require supplemental oxygen and continued to be tachypneic, with minimal activity. Initial diagnostic tests, including bronchoscopy with biopsy and lavage, did not reveal a diagnosis. She then underwent a video-assisted thoracoscopic surgery (VATS) lung biopsy. The biopsy slides showed suppurative granulomatous inflammation affecting greater than 50% of the parenchymal lung surface. Fungal hyphae consistent with Aspergillus were present in those granulomas. A diagnosis of CGD was made and she was started on Voriconazole. She improved with treatment. Her neutrophil burst test showed negative burst on stimulation, indicating phagocytic dysfunction consistent with CGD. Autosomal recessive CGD was confirmed by genetic testing. Conclusions: CGD can present in adulthood without any previous symptoms and signs. Clinicians should consider this disease in patients presenting with recurrent or non-resolving infections. Timely treatment and prophylaxis has been shown to reduce serious infections as well as mortality in these patients. PMID:28377567

We report a case of lung abscess caused by an ingested fish bone that was successfully treated by minimally invasive surgery. Although cases of ingested foreign body abscess are well reported, lung abscess caused by ingested fish bone is extremely rare. To date, less than 10 similar cases have been reported in the literature. To the best of our knowledge, the case presented in this case report is the first report of this kind that was successfully treated by video-assist thoracic surgery (VATS). A 47-year-old man was admitted to department of thoracic surgery with the complaint of continues dry cough and fever. The patient accidentally swallowed a long sharp-blade-shaped fish bone 20 days before, which perforated the upper thoracic esophagus on the right and embedded in the right upper lobe.The diagnosis was verified by computed tomography scan and a video-assist thoracic surgery procedure was successfully performed to treat the patient. The patient survived the esophageal perforation fortunately without involvement of great vessel injury and probable mediastinitis. This report may provide additional experience on lung abscess caused by ingested fish bones. However, it is also important to educate the public of the risks of trying to force an ingested object down into the stomach.

A 73-year-old woman who had been followed in our department of gynecology because of ovarian cancer since 2002, was admitted with liver dysfunction and complaining of back pain and light precordial chest pain. The chest radiograph on admission revealed a tumor in her left upper lung field, and chest CT revealed a tumor adjacent to the chest wall and mediastinum. FDG-positron emission tomography (PET) showed abnormal uptake in the tumor and Th6/7, and the subaortic lymph nodes. On the basis of these findings, primary lung cancer with bone metastasis was suspected. She had a high grade fever on admission, and blood cultures were positive for group G streptococcus. The treatment with intravenous penicillin was started. Percutaneous biopsy of the tumor in her left chest showed an abscess wall in the chest wall, but no evidence of malignancy. Transbronchial lung biopsy and CT-guided biopsy also showed no malignant cells. Since the tumor decreased in size and back pain improved gradually by only antibiotic treatment, a diagnosis of sepsis of group G streptococcus, chest wall abscess, and vertebral osteomyelitis was made. She was treated with intravenous penicillin for 4 weeks and oral amoxicillin for another 4 weeks. After 60 days of antibiotic treatment, the tumor vanished.

A single injection of ML29 reassortant vaccine for Lassa fever induces low, transient viremia, and low or moderate levels of ML29 replication in tissues of common marmosets depending on the dose of the vaccination. The vaccination elicits specific immune responses and completely protects marmosets against fatal disease by induction of sterilizing cell-mediated immunity. DNA array analysis of human peripheral blood mononuclear cells from healthy donors exposed to ML29 revealed that gene expression patterns in ML29-exposed PBMC and control, media-exposed PBMC, clustered together confirming safety profile of the ML29 in non-human primates. The ML29 reassortant is a promising vaccine candidate for Lassa fever. PMID:18692539

Due to the high mortality of lung cancer, there is a critical need to develop diagnostic procedures enabling early detection of the disease while at a curable stage. Targeted molecular imaging builds on the positive attributes of positron emission tomography/computed tomography (PET/CT) to allow for a noninvasive detection and characterization of smaller lung nodules, thus increasing the chances of positive treatment outcome. In this study, we investigate the ability to characterize lung tumors that spontaneously arise in a transgenic mouse model. The tumors are first identified with small animal CT followed by characterization with the use of small animal PET with a novel 64Cu-1,4,7,10-tetra-azacylododecane-N,N',N'',N'''-tetraacetic acid (DOTA)-knottin peptide that targets integrins upregulated during angiogenesis on the tumor associated neovasculature. The imaging results obtained with the knottin peptide are compared with standard 18F-fluorodeoxyglucose (FDG) PET small animal imaging. Lung nodules as small as 3 mm in diameter were successfully identified in the transgenic mice by small animal CT, and both 64Cu-DOTA-knottin 2.5F and FDG were able to differentiate lung nodules from the surrounding tissues. Uptake and retention of the 64Cu-DOTA-knottin 2.5F tracer in the lung tumors combined with a low background in the thorax resulted in a statistically higher tumor to background (normal lung) ratio compared with FDG (6.01±0.61 versus 4.36±0.68; P<0.05). Ex vivo biodistribution showed 64Cu-DOTA-knottin 2.5F to have a fast renal clearance combined with low nonspecific accumulation in the thorax. Collectively, these results show 64Cu-DOTA-knottin 2.5F to be a promising candidate for clinical translation for earlier detection and improved characterization of lung cancer.

Gefitinib (lressa) is the most prescribed drug, highly effective to treat of non-small cell lung cancer; primarily it was considered targeted therapy is a kinase inhibitor. The non-small cell lung cancer caused by the mutation in the Epithelial Growth Factor Receptor (EGFR) gene, Iressa works by blocking the EGFR protein that helps the cancer cell growth. EGFR protein has lead to the development of anticancer therapeutics directed against EGFR inhibitor including Gefitinib for non-small cell lung cancer. To explore research on Gefitinib and its derivatives interaction with crystal structure EGFR to understand the better molecular insights interaction strategies. Molecular modeling of ligands (Gefitinib and its derivatives) was carried out by Avogadro software till atomic angle stable confirmation obtained. The partial charges for the ligands were assigned as per standard protocol for molecular docking. All docking simulations were performed with AutoDockVina. Virtual screening carried out based on binding energy and hydrogen bonding affinity. Molecular dynamics (MD) and Simulation EGFR was done using GROMACS 5.1.1 software to explore the interaction stability in a cell. The stable conformation for EGFR protein trajectories were captured at various time intervals 0-20ns. Few compounds screen based on high affinity as the inhibitor for EGFR may inhibit the cell cycle signalling in non-small cell lung cancer. These result suggested that a computer aided screening approach of a Gefitinib derivatives compounds with regard to their binding to EGFR for identifying novel drugs for the treatment of non-small cell lung cancer.

Churg-Strauss syndrome (CSS) is a granulomatous small vessel vasculitis. It is characterized by asthma, allergic granulomatosis and vasculitis. This syndrome is rare in children. A 5 years old boy was admitted with cough, fever and dyspnea for 2 weeks. On the basis of laboratory data (peripheral eosinophilia), associated with skin biopsy, and history of CSS in his sister, this disease was eventually diagnosed. The patient had good response to corticosteroid. In every asthmatic patient with prolonged fever, eosinophilia and multisystemic involvment, CSS should be considered.

Sorafenib is a multi-kinase inhibitor currently approved in Japan for unresectable and/or metastatic renal cell carcinoma and unresectable hepatocellular carcinoma. Although drug-induced lung injury has recently been the focus of interest in Japanese patients treated with molecular targeting agents, the clinical features of patients receiving sorafenib remain to be completely investigated. All-patient post-marketing surveillance data was obtained within the frame of Special Drug Use Investigation; between April 2008 and March 2011, we summarized the clinical information of 62 cases with drug-induced lung injury among approximately 13,600 sorafenib-treated patients in Japan. In addition, we summarized the results of evaluation by a safety board of Japanese experts in 34 patients in whom pulmonary images were available. For the calculation of reporting frequency, interim results of Special Drug Use Investigation were used. In the sets of completed reports (2,407 in renal cell carcinoma and 647 in hepatocellular carcinoma), the reporting frequency was 0.33 % (8 patients; fatal, 4/8) and 0.62 % (4 patients; fatal, 2/4), respectively. Major clinical symptoms included dyspnea, cough, and fever. Evaluation of the images showed that 18 cases out of 34 patients had a pattern of diffuse alveolar damage. The patients with hepatocellular carcinoma showed a greater incidence and earlier onset of lung injury than those with renal cell carcinoma. Although the overall reporting frequency of sorafenib-induced lung injury is not considered high, the radiological diffuse alveolar damage pattern led to a fatal outcome. Therefore, early recognition of sorafenib-induced lung injury is crucial for physicians and patients.

Primary pleuropulmonary synovial sarcoma with brain metastases in a paediatric patient: an unusual presentation.

Primary lung neoplasms are rare in children. The most common primary lung malignancies in children are pleuropulmonary blastoma and carcinoid tumour. Synovial sarcoma (SS) accounts for approximately 1% of all childhood malignancies. In absolute terms, the SS of the lungs and pleura are extremely rare and pose a diagnostic difficulty. Soft tissue sarcomas usually have a high potential for metastases, however, metastasis to the brain is rare, even in widely disseminated disease, and it has been described only in 3 case reports previously. Primary pleuropulmonary SS with brain metastases is even rarer. Here we present a case of an 11-year-old boy who presented with respiratory complaints, viz. fever and cough for 20 days. Initial impression was lung abscess, however, on histopathological, immunohistochemical and molecular study, the disorder was diagnosed as synovial sarcoma. After a week from the first consult, the child developed neurological symptoms, viz., an episode of convulsion and gradually worsening power of the lower limb. Computed tomography scan and Magnetic Resonance Spectroscopy was suggestive of brain metastases. Given the rarity of primary lung neoplasms in children, clinical detection remains a challenge. Delayed diagnoses are common as respiratory symptoms may be attributed to inflammatory or infective processes. Primary pleuropulmonary synovial sarcoma is a rare tumour and it is not known to commonly metastasise to the brain. Though rare, primary pleuropulmonary SS should be considered an important differential among peadiatric primary lung neoplasms due to its potential for curability if detected early, and more aggressive metastatic pattern, e.g. brain metastases making early detection imperative.

Climate controls on valley fever incidence in Kern County, California

Zender, Charles S.; Talamantes, Jorge

2006-01-01

Coccidiodomycosis (valley fever) is a systemic infection caused by inhalation of airborne spores from Coccidioides immitis, a soil-dwelling fungus found in the southwestern United States, parts of Mexico, and Central and South America. Dust storms help disperse C. immitis so risk factors for valley fever include conditions favorable for fungal growth (moist, warm soil) and for aeolian soil erosion (dry soil and strong winds). Here, we analyze and inter-compare the seasonal and inter-annual behavior of valley fever incidence and climate risk factors for the period 1980-2002 in Kern County, California, the US county with highest reported incidence. We find weak but statistically significant links between disease incidence and antecedent climate conditions. Precipitation anomalies 8 and 20 months antecedent explain only up to 4% of monthly variability in subsequent valley fever incidence during the 23 year period tested. This is consistent with previous studies suggesting that C. immitis tolerates hot, dry periods better than competing soil organisms and, as a result, thrives during wet periods following droughts. Furthermore, the relatively small correlation with climate suggests that the causes of valley fever in Kern County could be largely anthropogenic. Seasonal climate predictors of valley fever in Kern County are similar to, but much weaker than, those in Arizona, where previous studies find precipitation explains up to 75% of incidence. Causes for this discrepancy are not yet understood. Higher resolution temporal and spatial monitoring of soil conditions could improve our understanding of climatic antecedents of severe epidemics.

An important mechanism for gene regulation utilizes small non-coding RNAs called microRNAs (miRNAs). These small RNAs play important roles in tissue development, cell differentiation and proliferation, lipid and fat metabolism, stem cells, exocytosis, diseases and cancers. To date, relatively little is known about functions of miRNAs in the lung except lung cancer. In this study, we utilized a rat miRNA microarray containing 216 miRNA probes, printed in-house, to detect the expression of miRNAs in the rat lung compared to the rat heart, brain, liver, kidney and spleen. Statistical analysis using Significant Analysis of Microarray (SAM) and Tukey Honestly Significant Difference (HSD) revealed 2 miRNAs (miR-195 and miR-200c) expressed specifically in the lung and 9 miRNAs co-expressed in the lung and another organ. 12 selected miRNAs were verified by Northern blot analysis. The identified lung-specific miRNAs from this work will facilitate functional studies of miRNAs during normal physiological and pathophysiological processes of the lung.

Thyroid metastasis of lung cancer is rarely observed in clinical practice. The primary cancers which metastasize to the thyroid gland are mostly renal cell carcinoma, lung cancer, and breast cancer. Transient destructive thyrotoxicosis is caused by massive metastasis of extrathyroid tumors. We herein present a case report of a patient with small cell carcinoma of lung with metastasis to the thyroid and thyrotoxicosis due to toxic multinodular goiter. A 66-year-old man complained of swelling around the right side of the neck, dyspnea, progressive weight loss, and palpitation starting since 3 months before his admission. The patient was diagnosed with small cell carcinoma of lung with metastasis to the thyroid and thyrotoxicosis due to toxic multinodular goiter. The case report presented here illustrates the challenge of making a definitive and adequate diagnosis, particularly if the patient presents with 2 potential causes of thyrotoxicosis. Thyroid scintigraphy is an important tool for differential diagnosis of thyrotoxicosis.

Non-small cell lung cancer: current treatment and future advances

Lung cancer has a poor prognosis; over half of people diagnosed with lung cancer die within one year of diagnosis and the 5-year survival is less than 18%. Non-small cell lung cancer (NSCLC) accounts for the majority of all lung cancer cases. Risk factors for developing NSCLC have been identified, with cigarette smoking being a major factor along with other environmental and genetic risk factors. Depending on the staging of lung cancer, patients are eligible for certain treatments ranging from surgery to radiation to chemotherapy as well as targeted therapy. With the advancement of genetics and biomarkers testing, specific mutations have been identified to better target treatment for individual patients. This review discusses current treatments including surgery, chemotherapy, radiotherapy, and immunotherapy as well as how biomarker testing has helped improve survival in patients with NSCLC.

Radiation pneumonitis is the most frequent acute pulmonary toxicity following stereotactic body radiation therapy for lung cancer. Here, we investigate clinical and dosimetric factors associated with symptomatic radiation pneumonitis in patients with stage I non-small cell lung cancer treated with stereotactic body radiation therapy. A total of 67 patients with stage I non-small cell lung cancer who received stereotactic body radiation therapy at our institution were enrolled, and their clinicopathological parameters and dosimetric parameters were recorded and analyzed. The median follow-up period was 26.4 months (range: 7-48 months). In univariate analysis, tumor size ( P = .041), mean lung dose ( P = .028), V2.5 ( P = .024), V5 ( P = .014), V10 ( P = .004), V20 ( P = .024), V30 ( P = .020), V40 ( P = .040), and V50 ( P = 0.040) were associated with symptomatic radiation pneumonitis. In multivariable logistic regression analysis, V10 ( P = .049) was significantly associated with symptomatic radiation pneumonitis. In conclusion, this study found that tumor size, mean lung dose, and V2.5 to V50 were risk factors markedly associated with symptomatic radiation pneumonitis. Our data suggested that lung V10 was the most significant factor, and optimizing lung V10 may reduce the risk of symptomatic radiation pneumonitis. For both central and peripheral stage I lung cancer, rate of radiation pneumonitis ≥grade 2 was low after stereotactic body radiation therapy with appropriate fraction dose.

Transmission by the oral route of Coxiella burnetii is controversial. Our objective was to evaluate dairy products in the transmission of Q fever. Pasteurized, unpasteurized, and thermized dairy products were tested for C. burnetii by using a quantitative polymerase chain reaction specific for IS1111 and IS30A spacers, culturing in human embryonic lung fibroblasts cells, and inoculation into BALB/c mice. We tested 201 products and C. burnetii was identified in 64%. Cow milk origin products were more frequently positive than goat or ewe products (P = 0.006 and P = 0.0001, respectively), and industrial food was more frequently positive than artisanal food (P < 0.0001). Food made from unpasteurized milk contained higher bacteria concentrations than food made from pasteurized milk (P = 0.02). All cultures were negative and mice did not show signs of illness. Farm animals are highly infected in France but consumption of cheese and yogurt does not seem to pose a public health risk for transmission of Q fever. PMID:23382158

In Panama, hantavirus pulmonary syndrome (HPS) is caused by Choclo virus, a species phylogenetically related to Andes and Maporal viruses. Up to 60% of the population has been positive for specific serum antibody in community-based surveys, but mortality is very uncommon. In four western Panama clinics, we tested individuals presenting with a severe febrile prodrome for acute hantavirus (HV) infection by immunoglobulin M enzyme-linked immunosorbent assay and reverse transcription polymerase chain reaction as well as clinically similar infections, such as dengue and leptospirosis. From 2006 to 2009, at least 21% of 117 patients diagnosed with HV infection had HV Fever (HF) with no evidence of pulmonary edema (no respiratory distress or radiographic lung infiltrates), and 44% of patients had very mild HPS (radiographic pulmonary edema but no respiratory insufficiency). HV infection caused by Choclo virus in Panama presents often as HF, which contrasts with HV in the Americas but is consistent with the high seroprevalence in endemic regions. PMID:23836565

Background. Histoplasma capsulatum is the most common endemic mycosis in the United States and is a frequent cause of opportunistic infection in immunodeficient hosts. Histoplasmosis is most often self-limiting and goes unrecognized in the immunocompetent population but can progress to disseminated histoplasmosis in patients with an impaired immune system. Liver involvement as a part of disseminated histoplasmosis which usually originates in the lung is well known. However, extrapulmonary hepatic histoplasmosis as a primary manifestation is extremely rare. Case Presentation. We report a rare case of histoplasmosis that presented as persistent fever and abnormal liver function tests in a 66-year-old female with rheumatoid arthritis, receiving infliximab. Conclusion. Emphasizing histoplasmosis as a major cause of acute granulomatous hepatitis and fever of unknown origin in cell mediated immunodeficient population, this case highlights the need for high index of suspicion and the importance of prompt diagnosis since any delay of treatment can be life threatening in this population.

A 60-year-old man presented with a 25-day history of acute onset instability of gait, tremulousness of limbs and involuntary eye movements. Examination revealed presence of opsoclonus, myoclonus and ataxia, without any loss of motor power in the limbs. Prompt investigations were directed towards identifying an underlying malignancy which is often associated with this type of clinical scenario. CT of the brain was normal and cerebrospinal fluid examination showed lymphocytic pleocytosis. A cavitatory lesion was found in the right lung base on the high-resolution CT of the chest and histopathological examination of this lung mass showed small cell lung carcinoma. The patient was managed symptomatically with levetiracetam and baclofen and referred to oncology department for resection of the lung mass.

Cigarette smoking is a well-known cause of interstitial lung disease (ILD), pulmonary emphysema and lung cancer. Coexisting pulmonary disease can affect prognosis in patients with lung cancer. The aim of this study was to determine the influence of pulmonary disease on outcomes in patients with a smoking history who had undergone surgery for pathological Stage I non-small-cell lung cancer. Medical records of 257 patients with a smoking history who underwent surgery for pathological Stage I non-small-cell lung cancer between June 2009 and December 2014 were reviewed. Coexisting ILDs were evaluated using high-resolution computed tomography. The degree of pulmonary emphysema was determined using image analysis software according to the Goddard classification. The impact of clinicopathological factors on outcome was evaluated. Among the 257 patients, ILDs were detected via high-resolution computed tomography in 60 (23.3%) patients; of these, usual interstitial pneumonia (UIP) patterns and non-UIP patterns were seen in 25 (9.7%) and 35 (13.6%) patients, respectively. The degree of pulmonary emphysema was classified as none, mild and moderate and included 50 (19.5%), 162 (63.0%) and 45 (17.5%) patients, respectively. The 5-year overall survival, cancer-specific survival and relapse-free survival were 80.7%, 88.0% and 74.9%, respectively, during a median follow-up period of 50.5 months. In multivariate analysis, the presence of a UIP pattern was shown to be an independent risk factor for poor outcome. The presence of a UIP-pattern ILD on high-resolution computed tomography images was shown to be a risk factor for poor outcome in patients with a smoking history who had undergone surgery for pathological Stage I non-small-cell lung cancer.

Rickettsiae are obligate intracellular bacteria responsible for many febrile syndromes around the world, including in sub-Saharan Africa. Vectors of these pathogens include ticks, lice, mites and fleas. In order to assess exposure to flea-associated Rickettsia species in Madagascar, human and small mammal samples from an urban and a rural area, and their associated fleas were tested. Anti-typhus group (TGR)- and anti-spotted fever group rickettsiae (SFGR)-specific IgG were detected in 24 (39%) and 21 (34%) of 62 human serum samples, respectively, using indirect ELISAs, with six individuals seropositive for both. Only two (2%) Rattus rattus out of 86 small mammals presented antibodies against TGR. Out of 117 fleas collected from small mammals, Rickettsia typhi, a TGR, was detected in 26 Xenopsylla cheopis (24%) collected from rodents of an urban area (n = 107), while two of these urban X. cheopis (2%) were positive for Rickettsia felis, a SFGR. R. felis DNA was also detected in eight (31%) out of 26 Pulex irritans fleas. The general population in Madagascar are exposed to rickettsiae, and two flea-associated Rickettsia pathogens, R. typhi and R. felis, are present near or in homes. Although our results are from a single district, they demonstrate that rickettsiae should be considered as potential agents of undifferentiated fever in Madagascar.

A man was admitted to the Johannesburg Hospital with a history of fever, diarrhoea, and dry cough for four days. He began to produce bloodstained sputum and was found to have severe arterial hypoxaemia. Radiography showed widespread opacification over both lung fields, and the clinical and haemodynamic features were consistent with the adult respiratory distress syndrome. Serology for Leptospira canicola was positive. Despite antibiotics, supportive therapy, and ventilation the patient died. Necropsy excluded cardiac disease. This case shows that leptospirosis may cause the adult respiratory distress syndrome. Images p520-a PMID:6790049

Coccidioidomycosis ("valley fever") is caused by inhaling spores of the soil-dwelling fungi Coccidioides immitis or Coccidioides posadasii. Most infections are subclinical. When clinical manifestations do occur (typically 1-4 weeks after exposure), they are similar to those associated with influenza or community-acquired pneumonia. Disseminated disease is rare. Residual pulmonary nodules can lead to chronic lung disease. Fluconazole or other triazoles often are used for treatment, but mild cases often resolve without specific therapy. A total of 17,802 cases were reported in the United States in 2012.

A 51-year-old man was admitted to our hospital because of dry cough and low grade fever with right-sided pleural fluid and blood eosinophilia. Warfarin had been prescribed following coronary artery bypass grafting. After the discontinuation of warfarin the clinical and chest X-ray findings improved; readministration of the drug caused recurrent blood eosinophilia and pleural effusion in the other lung. Since no other specific etiologies for eosinophilia and pleural effusion were determined by extensive evaluation, warfarin seemed to be associated with his illness. This is the first report of warfarin-induced eosinophilic pleurisy.

The authors report a case of a 20-year-old woman who was diagnosed with pulmonary cystic echinococcosis. She was admitted to hospital with a 1-week history of unresolving cough, coloured sputum with occasional haemoptysis and fever despite oral antibiotics. Radiology revealed a cavitating right lower lobe lung abscess. After 4 weeks of treatment, follow-up radiology showed incomplete resolution. Bronchoscopy revealed a white, avascular cystic lesion in the right lower lobe and serology testing for Echinococcus granulosus was positive. Repeat imaging eventually confirmed the cystic lesion with the 'air bubble'sign. A thorough travel history, a high index of clinical suspicion and close follow-up are essential in making a diagnosis of pulmonary cystic echinococcosis. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Fifteen 8-month-old fennec foxes imported from Sudan showed fever, mucopurulent ocular discharge, diarrhea, severe emaciation, seizures, and generalized ataxia, and died. Three of the 15 animals were presented for diagnostic investigation. Severe dehydration, brain congestion, and gastric ulcers were observed in all animals. In one animal, the lungs had failed to collapse and were multifocally dark red in appearance. Histopathologically, there were lymphohistiocytic meningoencephalitis with malacia, mild interstitial pneumonia, lymphoid depletion of lymphoid tissues and organs, and intestinal villous atrophy with intralesional coccidia. There were many intracytoplasmic and/or intranuclear inclusion bodies in the epithelial cells of the medullary velum, lungs, liver, kidneys, trachea, pancreas, stomach, gall bladder, urinary bladder, and ureters, and in macrophages of malacia foci and lymphocytes and macrophages of lymphoid organs. Additionally, intestinal coccidia were confirmed to be Isospora species by a fecal test. To our knowledge, this is the first report of canine distemper with intestinal coccidiosis in fennec fox.

We report the case of a 46-year-old woman with acute febrile symptom who had multiple pulmonary nodules and a renal mass. She underwent (18)F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) to find a hidden malignancy and the cause of her fever. FDG PET/CT images demonstrated a renal mass and multiple lung nodules with intense FDG uptake, which was suspicious of a renal malignancy with multiple pulmonary metastatic lesions. CT-guided biopsies of the pulmonary and renal lesions only showed chronic inflammatory infiltrates without evidence of malignancy. She was diagnosed with septic pulmonary embolism from a renal abscess. One month after antibiotic treatment, the follow-up chest and abdomen CT showed improvement of the lung and renal lesions. This is the first case demonstrating the FDG PET/CT finding of septic pulmonary embolism associated with renal abscess in the published literature.

Chronic active Epstein-Barr virus (CAEBV) infection is characterized by persistent infectious mononucleosis-like symptoms, an unusual pattern of Epstein-Barr virus (EBV) antibodies, detection of the EBV genome in affected tissues or peripheral blood, and chronic illness that cannot be attributed to any other known disease. This is the first reported Korean case of an immunocompetent adult with CAEBV-associated interstitial pneumonitis. A 28-year-old female was admitted with a fever that persisted for 3 weeks.

Chronic active Epstein-Barr virus (CAEBV) infection is characterized by persistent infectious mononucleosis-like symptoms, an unusual pattern of Epstein-Barr virus (EBV) antibodies, detection of the EBV genome in affected tissues or peripheral blood, and chronic illness that cannot be attributed to any other known disease. This is the first reported Korean case of an immunocompetent adult with CAEBV-associated interstitial pneumonitis. A 28-year-old female was admitted with a fever that persisted for 3 weeks. She had multiple lymphadenopathy, hepatosplenomegaly, pancytopenia, and elevated serum aminotransferase levels. Serology for antibodies was positive and chest computed tomography showed diffuse ground glass opacities in both lungs. Histopathology of the lung tissue showed lymphocyte infiltration, and EBV DNA was detected in those lymphocytes using in situ hybridization with an EBV-encoded RNA probe. After 1 month of hospitalization, she improved without specific treatment.

Combination therapy for advanced or metastatic non-small cell lung cancer will be tested in new clinical trial | Center for Cancer Research

Lung cancer (both small cell and non-small cell) is the second most common cancer in both men and women. The article represents results of evaluating of the plasma metabolic profiles of 100 lung cancer patients and 100 controls to investigate significant metabolites using 400 MHz 1H NMR spectrometer. The results of multivariate statistical analysis show that a medium-field NMR spectrometer can obtain the data which are already sufficient for clinical metabolomics.

In this work, we present a computer-aided detection (CAD) algorithm for small lung nodules on low-dose MSCT images. With this technique, identification of potential lung nodules is carried out with a local density maximum (LDM) algorithm, followed by reduction of false positives from the nodule candidates using task-specific 2-D/3-D features along with a knowledge-based nodule inclusion/exclusion strategy. Twenty-eight MSCT scans (40/80mAs, 120kVp, 5mm collimation/2.5mm reconstruction) from our lung cancer screening program that included at least one lung nodule were selected for this study. Two radiologists independently interpreted these cases. Subsequently, a consensus reading by both radiologists and CAD was generated to define a "gold standard". In total, 165 nodules were considered as the "gold standard" (average: 5.9 nodules/case; range: 1-22 nodules/case). The two radiologists detected 146 nodules (88.5%) and CAD detected 100 nodules (60.6%) with 8.7 false-positives/case. CAD detected an additional 19 nodules (6 nodules > 3mm and 13 nodules < 3mm) that had been missed by both radiologists. Preliminary results show that the CAD is capable of detecting small lung nodules with acceptable number of false-positives on low-dose MSCT scans and it can detect nodules that are otherwise missed by radiologists, though a majority are small nodules (< 3mm).

We developed a lung sound auscultation simulator "Mr. Lung" in 2001. To improve the auscultation skills of lung sounds, we utilized this new device in our educational training facility. From June 2001 to March 2002, we used "Mr. Lung" for our small group training in which one hundred of the fifth year medical students were divided into small groups from which one group was taught every other week. The class consisted of ninety-minute training periods for auscultation of lung sounds. At first, we explained the classification of lung sounds, and then auscultation tests were performed. Namely, students listened to three cases of abnormal or adventitious lung sounds on "Mr. Lung" through their stethoscopes. Next they answered questions corresponding to the portion and quality of the sounds. Then, we explained the correct answers and how to differentiate lung sounds on "Mr. Lung". Additionally, at the beginning and the end of the lecture, five degrees of self-assessment for the auscultation of the lung sounds were performed. The ratio of correct answers for lung sounds were 36.9% for differences between bilateral lung sounds, 52.5% for coarse crackles, 34.1% for fine crackles, 69.2% for wheezes, 62.1% for rhonchi and 22.2% for stridor. Self-assessment scores were significantly higher after the class than before. The ratio of correct lung sound answers was surprisingly low among medical students. We believe repetitive auscultation of the simulator to be extremely helpful for medical education.

Aspergillus colonization after lung transplantation may increase the risk for bronchiolitis obliterans syndrome (BOS), a disease of small airways. We hypothesized that colonization with small conidia Aspergillus species would be associated with a greater risk of BOS, based upon an increased likelihood of deposition in small airways. We studied adult primary lung recipients from two large centers; 298 recipients at University of California, Los Angeles and 482 recipients at Duke University Medical Center. We grouped Aspergillus species by conidia diameter ≤3.5μm. We assessed the relationship of colonization with outcomes in Cox models. Pre-BOS colonization with small conidia Aspergillus species, but not large, was a risk factor for BOS (P = 0.002, HR 1.44, 95% CI 1.14–1.82), along with acute rejection, single lung, and Pseudomonas. Colonization with small conidia species also associated with risk of death (P = 0.03, HR 1.30, 95% CI 1.03–1.64). Although other virulence traits besides conidia size may be important, we have demonstrated in two large independent cohorts that colonization with small conidia Aspergillus species increases the risk of BOS and death. Prospective evaluation of strategies to prevent Aspergillus colonization of small airways is warranted, with the goal of preserving lung allograft function as long as possible. PMID:23398785

Adenosquamous carcinoma of the lung diagnosed by cytology?: a diagnostic dilemma.

2012-09-01

Adenosquamous cell carcinomas of the lung are rare tumours and are associated with a poor prognosis compared to other non-small cell carcinomas. We report a case of a solitary lung carcinoma evaluated by bronchial brush and lavage cytology, bronchial biopsy and pleural fluid cytology. Cytological assessment of the pleural fluid demonstrated non-small cell carcinoma and immunohistochemical staining confirmed a metastatic lung adenocarcinoma. The bronchial brush and lavage specimens, however, demonstrated the cytomorphological features of squamous cell carcinoma, which was confirmed by the bronchial biopsy. The finding of a mixed squamous and glandular component predicts a poor prognosis for this patient. The identification of a squamous component with the non-small cell carcinoma is important as this excludes the patient from anti-VEGF monoclonal antibody treatment due to the increased risk of haemorrhage.

After primary infection with Coxiella burnetii, patients may develop acute Q fever, which is a relatively mild disease. A small proportion of patients (1%-5%) develop chronic Q fever, which is accompanied by high mortality and can be manifested as infected arterial or aortic aneurysms or infected vascular prostheses. The disease can be complicated by arterial fistulas, which are often fatal if they are left untreated. We aimed to assess the cumulative incidence of arterial fistulas and mortality in patients with proven chronic Q fever. In a retrospective, observational study, the cumulative incidence of arterial fistulas (aortoenteric, aortobronchial, aortovenous, or arteriocutaneous) in patients with proven chronic Q fever (according to the Dutch Chronic Q Fever Consensus Group criteria) was assessed. Proven chronic Q fever with a vascular focus of infection was defined as a confirmed mycotic aneurysm or infected prosthesis on imaging studies or positive result of serum polymerase chain reaction for C. burnetii in the presence of an arterial aneurysm or vascular prosthesis. Of 253 patients with proven chronic Q fever, 169 patients (67%) were diagnosed with a vascular focus of infection (42 of whom had a combined vascular focus and endocarditis). In total, 26 arterial fistulas were diagnosed in 25 patients (15% of patients with a vascular focus): aortoenteric (15), aortobronchial (2), aortocaval (4), and arteriocutaneous (5) fistulas (1 patient presented with both an aortocaval and an arteriocutaneous fistula). Chronic Q fever-related mortality was 60% for patients with and 21% for patients without arterial fistula (P < .0001). Primary fistulas accounted for 42% and secondary fistulas for 58%. Of patients who underwent surgical intervention for chronic Q fever-related fistula (n = 17), nine died of chronic Q fever-related causes (53%). Of patients who did not undergo any surgical intervention (n = 8), six died of chronic Q fever-related causes (75%). The proportion of patients with proven chronic Q fever developing primary or secondary arterial fistulas is high; 15% of patients with a vascular focus of infection develop an arterial fistula. This observation suggests that C. burnetii, the causative agent of Q fever, plays a role in the development of fistulas in these patients. Chronic Q fever-related mortality in patients with arterial fistula is very high, in both patients who undergo surgical intervention and patients who do not.

Favipiravir is approved in Japan to treat novel or re-emerging influenza viruses, and is active against a broad spectrum of RNA viruses, including Ebola. Ribavirin is the only other licensed drug with activity against multiple RNA viruses. Recent studies show that ribavirin and favipiravir act synergistically to inhibit bunyavirus infections in cultured cells and laboratory mice, likely due to their different mechanisms of action. Convalescent immune globulin is the only approved treatment for Argentine hemorrhagic fever caused by the rodent-borne Junin arenavirus. We previously reported that favipiravir is highly effective in a number of small animal models of Argentine hemorrhagic fever. We now report that addition of low dose of ribavirin synergistically potentiates the activity of favipiravir against Junin virus infection of guinea pigs and another arenavirus, Pichinde virus infection of hamsters. This suggests that the efficacy of favipiravir against hemorrhagic fever viruses can be further enhanced through the addition of low-dose ribavirin. Copyright © 2015 Elsevier B.V.

Host cellular endoplasmic reticulum α-glucosidases I and II are essential for the maturation of viral glycosylated envelope proteins that use the calnexin mediated folding pathway. Inhibition of these glycan processing enzymes leads to the misfolding and degradation of these viral glycoproteins and subsequent reduction in virion secretion. We previously reported that, CM-10-18, an imino sugar α-glucosidase inhibitor, efficiently protected the lethality of dengue virus infection of mice. In the current study, through an extensive structure-activity relationship study, we have identified three CM-10-18 derivatives that demonstrated superior in vitro antiviral activity against representative viruses from four viral families causing hemorrhagic fever. Moreover, the three novel imino sugars significantly reduced the mortality of two of the most pathogenic hemorrhagic fever viruses, Marburg virus and Ebola virus, in mice. Our study thus proves the concept that imino sugars are promising drug candidates for the management of viral hemorrhagic fever caused by variety of viruses. Copyright © 2013 Elsevier B.V.

Polyamidoamine (PAMAM) dendrimers are a promising class of nanocarrier with applications in both small and large molecule drug delivery. Here we report a comprehensive evaluation of the uptake and transport pathways that contribute to the lung disposition of dendrimers. Anionic PAMAM dendrimers and control dextran probes were applied to an isolated perfused rat lung (IPRL) model and lung epithelial monolayers. Endocytosis pathways were examined in primary alveolar epithelial cultures by confocal microscopy. Molecular interactions of dendrimers with protein and lipid lung fluid components were studied using small angle neutron scattering (SANS). Dendrimers were absorbed across the intact lung via a passive, size-dependent transport pathway at rates slower than dextrans of similar molecular sizes. SANS investigations of concentration-dependent PAMAM transport in the IPRL confirmed no aggregation of PAMAMs with either albumin or dipalmitoylphosphatidylcholine lung lining fluid components. Distinct endocytic compartments were identified within primary alveolar epithelial cells and their functionality in the rapid uptake of fluorescent dendrimers and model macromolecular probes was confirmed by co-localisation studies. PAMAM dendrimers display favourable lung biocompatibility but modest lung to blood absorption kinetics. These data support the investigation of dendrimer-based carriers for controlled-release drug delivery to the deep lung.

Lung cancer, of which non-small-cell lung cancer comprises the majority, is the leading cause of cancer-related deaths in the United States and worldwide. Lung adenocarcinomas are a major subtype of non-small-cell lung cancers, are increasing in incidence globally in both males and females and in smokers and non-smokers, and are the cause for almost 50% of deaths attributable to lung cancer. Lung adenocarcinoma is a tumour with complex biology that we have recently started to understand with the advent of various histological, transcriptomic, genomic and proteomic technologies. However, the histological and molecular pathogenesis of this malignancy is still largely unknown. This review will describe advances in the molecular pathology of lung adenocarcinoma with emphasis on genomics and DNA alterations of this disease. Moreover, the review will discuss recognized lung adenocarcinoma preneoplastic lesions and current concepts of the early pathogenesis and progression of the disease. We will also portray the field cancerization phenomenon and lineage-specific oncogene expression pattern in lung cancer and how both remerging concepts can be exploited to increase our understanding of lung adenocarcinoma pathogenesis for subsequent development of biomarkers for early detection of adenocarcinomas and possibly personalized prevention.

Although liver metastasis is commonly found in cancer patients, fulminant hepatic failure secondary to diffuse cancer infiltration into the liver is rare. Liver metastasis-induced fulminant hepatic failure has been reported in patients with primary cancer of the gastrointestinal tract, breast and uroepithelium, and in patients with melanoma and hematologic malignancy. Small cell lung cancer is so highly invasive that hepatic metastasis is common, but rapid progression to fulminant hepatic failure is extremely rare. We report here on a case of a patient who died because of rapid progression to fulminant hepatic failure as a result of hepatic metastasis of small cell lung carcinoma.

Since Vi antigen is limited primarily to Salmonella typhi, it has been thought that detection of the antigen may be a useful method for diagnosing acute typhoid fever. The slide coagglutination method and enzyme-linked immunosorbent assay have recently been suggested as ways to detect small quantities of Vi antigen in urine. In Santiago, Chile, we compared the results of these two methods in patients with acute typhoid fever, paratyphoid fever, and other febrile illnesses and in afebrile control subjects. Using a cut-off value that maximally separated typhoid patients from controls, the enzyme-linked immunosorbent assay was positive in 62.4% of 141 patients with culture-proven typhoid infections and in 13.2% of 159 afebrile control subjects. The enzyme-linked immunosorbent assay was false positive in 64.7% of 34 culture-proven paratyphoid A or B patients and 47.1% of 21 patients with other nontyphoidal febrile illnesses. The coagglutination test was positive in 34% of typhoid patients, 14% of afebrile control subjects, and 46% of febrile control subjects. We conclude that these tests when performed with the Vi antibodies employed in this study are of little value for the diagnosis of typhoid fever in this setting. PMID:6630465

Retinoic acid-inducible gene-I (RIG-I)-like receptors (RLRs) are pattern-recognition receptors that recognize pathogen-associated molecular patterns and induce antiviral immune responses. Recent studies have demonstrated that RLR activation induces antitumor immunity and cytotoxicity against different types of cancer, including lung cancer. However a previous report has demonstrated that ionizing radiation exerts a limited effect on RLR in human monocytic cell-derived macrophages, suggesting that RLR agonists may be used as effective immunostimulants during radiation therapy. However, it is unclear whether ionizing radiation affects the cytotoxicity of RLR agonists against cancer cells. Therefore, in the present study the effects of cotreatment with ionizing radiation and RLR agonists on cytotoxicity against human non-small cell lung cancer cells A549 and H1299 was investigated. Treatment with RLR agonist poly(I:C)/LyoVec™ [poly(I:C)] exerted cytotoxic effects against human non-small cell lung cancer. The cytotoxic effects of poly(I:C) were enhanced by cotreatment with ionizing radiation, and poly(I:C) pretreatment resulted in the radiosensitization of non-small cell lung cancer. Furthermore, cotreatment of A549 and H1299 cells with poly(I:C) and ionizing radiation effectively induced apoptosis in a caspase-dependent manner compared with treatment with poly(I:C) or ionizing radiation alone. These results indicate that RLR agonists and ionizing radiation cotreatment effectively exert cytotoxic effects against human non-small cell lung cancer through caspase-mediated apoptosis.

TRIM28 is a universal corepressor for Kruppel-associated box zinc finger proteins. In this study, we demonstrated the expression of TRIM28 gene was significantly higher in cancerous tissues than in noncancerous tissues (P < 0.001). TRIM28 knockdown resulted in a decrease in cell proliferation in liquid media as well as in soft agar. The proliferation rate was impaired and the cell cycle progression was inhibited after knockdown of TRIM28 in non-small cell lung cancer cell lines PAa and SK-MES-1. We used real-time polymerase chain reaction to detect circulating cancer cells in 138 non-small cell lung cancer patients. The overall positive detection rate was 30.4% (42 of 138) in peripheral blood of NSCLC patients and was 29.9% (29 of 97) in early-stage patients. In a 70-month follow-up study, 20 of 29 patients (69.0%) in TRIM28 positive group had recurrence and/or metastasis, significantly higher (P = 0.004) than in the TRIM28 negative group (25 of 68, 36.8%). In addition, non-small cell lung cancer patients whose circulating cancer cells expressed TRIM28 suffered shorter tumor-specific survival compared with those with absent TRIM28 expression (P < 0.001). Results of our study showed that TRIM28 provides a survival advantage to lung cancer cells and may be a new marker to predict metastasis and prognosis in early-stage non-small cell lung cancer patients.

In the past decade, a shift toward targeted therapies in non-small-cell lung cancer following molecular profiling has dramatically changed the way advanced adenocarcinoma is treated. However, tumor cells inevitably acquire resistance to such therapies, circumventing any sustained clinical benefit. As the genomic classification of lung cancer continues to evolve and as the mechanisms of acquired resistance to targeted therapies become elucidated and more improved target-specific drugs come into sight, the future will see more promising results from the clinic through the development of new therapeutic strategies to overcome, or prevent the development of, resistance for lung cancer patients.

The importance of the adaptive immune response, specifically the role of regulatory T (Treg) cells in controlling the obstruction progression in smokers, has been highlighted. To quantify the adaptive immune cells in different lung compartments, we used lung tissues from 21 never-smokers without lung disease, 22 current and/or ex-smokers without lung disease (NOS) and 13 current and/or ex-smokers with chronic obstructive pulmonary disease (COPD) for histological analysis. We observed increased T, B, IL-17 and BAFF + cells in small and large airways of COPD individuals; however, in the NOS, we only observed increase in T and IL-17 + cells only in small airways. A decrease in the density of Treg + , TGF-β + and IL-10 + in small and large airways was observed only in COPD individuals. In the lymphoid tissues, Treg, T,B-cells and BAFF + cells were also increased in COPD; however, changes in Treg inhibitory associated cytokines were not observed in this compartment. Therefore, our results suggest that difference in Treg + cell distributions in lung compartments and the decrease in TGF-β + and IL-10 + cells in the airways may lead to the obstruction in smokers.

The consequences of failing to notice fever in children can be serious. On the other hand, false positive reading can result in unnecesery investigation or diagnostic approach. The aim of this study was to compare different ways of body temperature measurement. This prospective study was carried out on Pediatric Department of General Hospital in Subotica during 10 months (March-December 2006). In 263 children aged 1 month to 18 years of age, the body temperature was obtained from 4 measurement sites: tactile assesment, forehead and ear by electronic thermometer, rectal temperature in small children (up to 2 years of age) or axillar temperature in older children by mercury thermometer. Tympanic thermometry was considered as a standard for fever detection. The sensitivity of rectal temperature to detect fever is 46.67%, while specificity is 92.19%. The sensitivity of fever detection by electronic thermometry on the forehead is lower according to rectal thermometry - 36.08%, while specificity is 95.18%. The lowest values ofsensitivity are recorded in axillar thermometry (35.82%), specificity is 90.20%. The correlation coefficient is higher between tympanic and rectal temperature measurement (r=0.5076, p<0.0005), than between tympanic and forehead measurements (r=0.5076, p<0,0005), while the lowest was between tympanic and axillar mesurement sites (r=0.4933, p<0.0005). The results of our study and literature data show that the most accurate methods of thermometry are rectal measurement of body temperature in small children and tympanic thermometry in children over 2 years of age.

Advantages of CT scanners with high resolution have allowed the improved detection of lung cancers. In the recent release of positive results from the National Lung Screening Trial (NLST) in the US showing that CT screening does in fact have a positive impact on the reduction of lung cancer related mortality. While this study does show the efficacy of CT based screening, physicians often face the problems of deciding appropriate management strategies for maximizing patient survival and for preserving lung function. Several key manifold-learning approaches efficiently reveal intrinsic low-dimensional structures latent in high-dimensional data spaces. This study was performed to investigate whether the dimensionality reduction can identify embedded structures from the CT histogram feature of non-small-cell lung cancer (NSCLC) space to improve the performance in predicting the likelihood of RFS for patients with NSCLC.

Lung carcinogenesis is strongly influenced by environmental and heritable factors. The genetic contribution to the different histologies is unknown. A population-based computerized genealogy resource linked to a statewide cancer registry of lung cancer cases (n=5408) was analyzed to evaluate the heritable contribution to lung cancer histology in smoking (n=1751) and non-smoking cases (n=818). Statistical methods were used to test for significant excess relatedness of lung cancer cases. Significant excess distant relatedness was observed for all lung cancer histology subgroups analyzed except the small cell lung cancer subset (p=0.213). When smoking and non-smoking histologic subsets of lung cancer were considered, excess relatedness was observed only in non-smoking NSCLC (n=653; p=0.026) and, particularly, in those non-smokers with non-squamous histology (n=561; p=0.036). Sixty one pedigrees were identified which demonstrated a significant excess risk of non-smoking, non-squamous lung cancer cases; and an excess of female cases was observed among the cases in these high-risk pedigrees. This analysis supports a genetic predisposition to lung cancer carcinogenesis in non-smoking, non-squamous NSCLC cases. Copyright © 2018 International Association for the Study of Lung Cancer.

Lung cancer: biology and treatment options

PubMed Central

Hassan, Omer; Yang, Yi-Wei; Buchanan, Petra

2015-01-01

Lung cancer remains the leading cause of cancer mortality in men and women in the U.S. and worldwide. About 90% of lung cancer cases are caused by smoking and the use of tobacco products. However, other factors such as radon gas, asbestos, air pollution exposures, and chronic infections can contribute to lung carcinogenesis. In addition, multiple inherited and acquired mechanisms of susceptibility to lung cancer have been proposed. Lung cancer is divided into two broad histologic classes, which grow and spread differently: small-cell lung carcinomas (SCLC) and non-small cell lung carcinomas (NSCLC). Treatment options for lung cancer include surgery, radiation therapy, chemotherapy, and targeted therapy. Therapeutic-modalities recommendations depend on several factors, including the type and stage of cancer. Despite the improvements in diagnosis and therapy made during the past 25 years, the prognosis for patients with lung cancer is still unsatisfactory. The responses to current standard therapies are poor except for the most localized cancers. However, a better understanding of the biology pertinent to these challenging malignancies, might lead to the development of more efficacious and perhaps more specific drugs. The purpose of this review is to summarize the recent developments in lung cancer biology and its therapeutic strategies, and discuss the latest treatment advances including therapies currently under clinical investigation.

Identifying metastatic tumor growth at an early stage has been one of the biggest challenges in the treatment of lung cancer. By genetic lineage tracing approach in a conditional model of Non-Small Cell Lung Cancer (NSCLC) in mice, we demonstrate that cystic lesions represent an early stage of metastatic invasion. We generated a mouse model for NSCLC which incorporated a heritable DsRed fluorescent tag driven by the ubiquitous CAG promoter in the alveolar type II cells of the lung. We found early cystic lesions in a secondary organ (liver) that lacked the expression of bona fide lung makers namely Scgb1a1 and surfactant protein C Sftpc and were DsRed positive hence identifying lung as their source of origin. This demonstrates the significant potential of alveolar type II cells in orchestrating the process of metastasis, rendering it as one of the target cell types of the lung of therapeutic importance in human NSCLC.

Oncogene-specific changes in cellular signaling have been widely observed in lung cancer. Here, we investigated how these alterations could affect signaling heterogeneity and suggest novel therapeutic strategies. We compared signaling changes across six human bronchial epithelial cell (HBEC) strains that were systematically transformed with various combinations of TP53, KRAS, and MYC-oncogenic alterations commonly found in non-small cell lung cancer (NSCLC).

Acute intestinal obstruction due to metastatic lung cancer—case report

PubMed Central

2017-01-01

Abstract We present a case of male patient, who was referred to our department because of acute intestinal obstruction, which was the initial clinical symptom of primary lung cancer. The abdominal computed tomography (CT) prior to the emergency operation showed small intestinal obstruction and metastases to both adrenal glands. The patient underwent an emergency abdominal exploratory laparotomy, that confirmed small bowel obstruction and diffuse metastatic lesions along the entire small bowel length. During the operation we took a sample of one metastasis for pathological examination and we created an intestinal bypass to relieve small bowel obstruction. The pathologist suspected to primary lung cancer according to the immunohistochemical staining. The chest CT after the emergency operation showed a large primary tumor in the left upper pulmonary lobe. PMID:28458837

Cordes, D O; Perry, B D; Rikihisa, Y; Chickering, W R

1986-07-01

Potomac horse fever was reproduced in 15 ponies by transfusion of whole blood originally from two natural cases and subsequently from ponies infected by the transfusions. Incubation periods varied from 9 to 15 days. Affected ponies developed varying degrees of fever, diarrhea, anorexia, depression, and leukopenia. Eleven affected ponies were killed, three died in the acute phase of the disease, and one did not show clinical signs. The most consistent post-mortem findings were fluid contents in the cecum and large colon, and areas of hyperemia (of inconstant degree and distribution) in mucosae of both small and large intestines. Multifocal areas of necrosis occurred in mucous membranes. Ehrlichial organisms were most common in the cytoplasm of epithelial cells, macrophages, and mast cells of the large colon.

Ebola and Marburg Hemorrhagic Fevers: Neglected Tropical Diseases?

PubMed Central

MacNeil, Adam; Rollin, Pierre E.

2012-01-01

Ebola hemorrhagic fever (EHF) and Marburg hemorrhagic fever (MHF) are rare viral diseases, endemic to central Africa. The overall burden of EHF and MHF is small in comparison to the more common protozoan, helminth, and bacterial diseases typically referred to as neglected tropical diseases (NTDs). However, EHF and MHF outbreaks typically occur in resource-limited settings, and many aspects of these outbreaks are a direct consequence of impoverished conditions. We will discuss aspects of EHF and MHF disease, in comparison to the “classic” NTDs, and examine potential ways forward in the prevention and control of EHF and MHF in sub-Saharan Africa, as well as examine the potential for application of novel vaccines or antiviral drugs for prevention or control of EHF and MHF among populations at highest risk for disease.

2017-01-01

Familial Mediterranean fever (FMF) is the most common hereditary auto-inflammatory (periodic fever) syndrome, and usually successfully treated with colchicine. However, nearly 5-10% of FMF cases are resistant or intolerant to colchicine and treatment options are highly restricted in these cases. Biologics including anakinra, canakinumab, rilonacept, etanercept, infliximab, interferon-alpha, and tocilizumab are shown to have efficacy to control FMF attacks. Tofacitinib, a Janus kinase (JAK) inhibitor, is an orally administered non-biologic disease modifying anti-rheumatic drug for the treatment of rheumatoid arthritis (RA). Herein we report a female patient with coexisting RA and colchicine resistant FMF whose FMF attacks and disease activity were completely controlled after treatment with tofacitinib, a small-molecule JAK3 inhibitor.

The Role of Collateral Paths in Long-Range Diffusion of 3He in Lungs

2008-01-01

Rationale and Objectives The hyperpolarized 3He long-range diffusion coefficient (LRDC) in lungs is sensitive to changes in lung structure due to emphysema, reflecting the increase in collateral paths resulting from tissue destruction. However, no clear understanding of LRDC in healthy lungs has emerged. Here we compare LRDC measured in healthy lungs with computer simulations of diffusion along the airway tree with no collateral connections. Materials and Methods Computer simulations of diffusion of spatially modulated spin magnetization were performed in computer generated, symmetric-branching models of lungs and compared with existing LRDC measurements in canine and human lungs. Results The simulations predict LRDC values of order 0.001 cm2/s, approximately 20 times smaller than the measured LRDC. We consider and rule out possible mechanisms for LRDC not included in the simulations: incomplete breath hold, cardiac motion, and passage of dissolved 3He through airway walls. However, a very low density of small (micron) holes in the airways is shown to account for the observed LRDC. Conclusion It is proposed that LRDC in healthy lungs is determined by small collateral pathways. PMID:18486004

From the aspect of the contemporary pathologic diagnostics of lung cancer the tissue obtained is a key issue since small biopsies and cytology still play a major role. In the non-small cell lung cancer era cytology is considered equal to biopsy however, in recent years it is unable to provide quality diagnosis and must be replaced by biopsy. Various molecular techniques can handle various different tissue samples which must be considered during molecular pathology diagnosis. Moreover, tumor cell-normal cell ratio in the obtained tissue, as well as the absolute tumor cell number have great significance, which information must be provided in the primary lung cancer diagnosis. Last but not least, for continuous sustainable molecular diagnostics of lung cancer rational algorithms, affordable technology and appropriate reimbursement are equally necessary.

This study was undertaken to analyze and compare the clinical characteristics and survival difference among veterans and civilians in Taiwan with lung cancer, especially non-small-cell lung cancer, and to determine whether or not veterans have a poorer prognosis than civilians. We retrospectively reviewed the medical records and computer files of lung cancer patients diagnosed between 1996 and 2000 at our hospital. Patients' clinical characteristics, marital status, staging, treatment modality, and overall survival were analyzed and compared, based on the patients' standing as veterans or civilians. During this period, 3,727 lung cancer patients (2,386 veterans, 1,341 civilians) were diagnosed. The overall survival of all lung cancer patients showed that civilians had better survival than veterans (median, 12 months vs. 8 months, p < 0.001). Survival of non-small-cell lung cancer patients was also better for civilians than veterans (median, 13 months vs. 9 months, p < 0.001). Surgery was the main treatment modality in both stage I and II civilians and veterans. A greater proportion of veterans in stage II and III received radiotherapy than civilians in the same stage, with a statistically significant difference in stage III patients (p < 0.001). Multivariate survival analysis showed that age and sex were independent risk factors for mortality, while standing (veteran or civilian) was not, in both all lung cancers and non-small-cell lung cancer alone. Veterans, who mainly came from China, had a poorer prognosis than civilians when suffering from lung cancer in Taiwan, due to age and gender, rather than standing.

Coiled-coil domain-containing protein 8 inhibits the invasiveness and migration of non-small cell lung cancer cells.

Lung cancer has always been the leading cause of death among patients with malignant tumors, and the majority of these patients die because of cancer cell invasion and metastasis. Previous studies have implicated coiled-coil domain-containing protein 8 (CCDC8) as a tumor suppressor in several types of cancer, such as breast and prostate cancers. However, the expression levels or functions of CCDC8 in lung cancer have not been elucidated. Here, we used immunohistochemical staining to measure CCDC8 expression in 147 samples from tumors and 30 samples from the adjacent normal lung tissues of patients with non-small cell lung cancer. CCDC8 was shown to be located predominantly in the cytoplasm and partially on the cell membrane, and its expression level was significantly lower in lung cancer samples than that in the adjacent normal lung tissues (P=.001). CCDC8 expression was closely related to tumor differentiation (P=.039), tumor-node-metastasis stage (P=.009), lymph node metastasis (P=.038), and prognosis (P=.043) of lung cancer. Transfection of A549 cells with CCDC8 significantly reduced cell invasion and migration (P<.05), whereas the invasiveness and migration capacity in CCDC8-knockdown A549 cells were significantly increased in comparison with the control cells (P<.05). Furthermore, we demonstrated that CCDC8 can downregulate the expression of Snail and upregulate the expression of E-cadherin by inhibiting p-P38 and p-IκBα. Collectively, CCDC8 may suppress the invasion and metastasis of lung cancer cells, and it may represent a promising therapeutic target for non-small cell lung cancer. Copyright © 2016 Elsevier Inc.

Rift Valley fever virus (RVFV) is a vector-borne RNA virus affecting humans, livestock and wildlife. In October/November 2010, after a period of unusually heavy rainfall, a Rift Valley fever outbreak occurred in northern Mauritania causing clinical cases in cattle, sheep, goats and camels, 21 of which were of lethal outcome. The aim of this study was to obtain further information on the continuation of RVF virus activity and spread in animal species in Mauritania after this outbreak. We therefore tested sera from small ruminants, cattle and camels for the presence of viral RNA and antibodies against RVFV. These sera were collected in different parts of the country from December 2010 to February 2011 and tested with three different ELISAs and an indirect immunofluorescence assay. The results show a high seroprevalence of RVFV IgM and IgG antibodies of about 57% in all animals investigated. Moreover, in four camel sera, viral RNA was detected emphasizing the important role camels played during the latest RVF outbreak in Mauritania. The study demonstrates the continuous spread of RVFV in Mauritania after initial emergence and highlights the potential role of small ruminants and camels in virus dissemination. © 2013 Blackwell Verlag GmbH.

Singapore Cancer Network (SCAN) Guidelines for Adjuvant Chemotherapy in Resected Non-Small Cell Lung Cancer.

2015-10-01

The SCAN lung cancer workgroup aimed to develop Singapore Cancer Network (SCAN) clinical practice guidelines for the use of adjuvant systemic therapy for non-small cell lung cancer in Singapore. The workgroup utilised a modified ADAPTE process to calibrate high quality international evidence-based clinical practice guidelines to our local setting. Five international guidelines were evaluated- those developed by the National Comprehensive Cancer Network (2014), European Society of Medical Oncology (2014), National Institute of Clinical Excellence (2012), Scottish Intercollegiate Guidelines Network (2014), and the Cancer Care Council Australia (2012). Recommendations on the selection of patients, chemotherapy regimen, treatment for stage I disease, treatment for positive margins and treatment options for pN2 disease with negative margins were produced. These adapted guidelines form the SCAN Guidelines 2015 for adjuvant systemic therapy of non-small cell lung cancer.

Lung cancer is characterized by the highest incidence of solid tumor-related brain metastases, which are reported with a growing incidence during the last decade. Prognostic assessment may help to identify subgroups of patients that could benefit from more aggressive therapy of metastatic disease, in particular when central nervous system is involved. The recent sub-classification of non-small cell lung cancer (NSCLC) into molecularly-defined "oncogene-addicted" tumors, the emergence of effective targeted treatments in molecularly defined patient subsets, global improvement of advanced NSCLC survival as well as the availability of refined new radiotherapy techniques are likely to impact on outcomes of patients with brain dissemination. The present review focuses on key evidence and research strategies for systemic treatment of patients with central nervous system involvement in non-small cell lung cancer.

The CXCR4/SDF-1 chemokine receptor axis: a new target therapeutic for non-small cell lung cancer.

PubMed

Otsuka, Shannon; Bebb, Gwyn

2008-12-01

Chemokines are proinflammatory chemoattractant cytokines that regulate cell trafficking and adhesion. The CXCR4 chemokine receptor and its ligand, stromal cell derived factor (SDF-1), constitute a chemokine/receptor axis that has attracted great interest because of an increasing understanding of its role in cancer, including lung cancer. The CXCR4/SDF-1 complex activates several pathways that mediate chemotaxis, migration and secretion of angiopoietic factors. Neutralization of SDF-1 by anti-SDF-1 or anti-CXCR4 monoclonal antibody in preclinical in vivo studies results in a significant decrease of non-small cell lung cancer metastases. Since anti-SDF-1/CXCR4 strategies have already been developed for use in combating human immunodeficiency virus infections, it is likely that these approaches will be used in clinical trials in non-small cell lung cancer in the very near future.

Purpose: Small-cell carcinoma of the bladder (SCCB) is a rare and aggressive neuroendocrine tumor with a dismal prognosis and limited treatment options. As SCCB is histologically indistinguishable from small-cell lung cancer, a shared pathogenesis and cell of origin has been proposed. The aim of this study is to determine whether SCCBs arise from a preexisting urothelial carcinoma or share a molecular pathogenesis in common with small-cell lung cancer. Experimental Design: We performed an integrative analysis of 61 SCCB tumors to identify histology- and organ-specific similarities and differences. Results: SCCB has a high somatic mutational burden driven predominantly by an APOBEC-mediated mutational process. TP53, RB1 , and TERT promoter mutations were present in nearly all samples. Although these events appeared to arise early in all affected tumors and likely reflect an evolutionary branch point that may have driven small-cell lineage differentiation, they were unlikely the founding transforming event, as they were often preceded by diverse and less common driver mutations, many of which are common in bladder urothelial cancers, but not small-cell lung tumors. Most patient tumors (72%) also underwent genome doubling (GD). Although arising at different chronologic points in the evolution of the disease, GD was often preceded by biallelic mutations in TP53 with retention of two intact copies. Conclusions: Our findings indicate that small-cell cancers of the bladder and lung have a convergent but distinct pathogenesis, with SCCBs arising from a cell of origin shared with urothelial bladder cancer.

Fusarium Infection in Lung Transplant Patients

Carneiro, Herman A.; Coleman, Jeffrey J.; Restrepo, Alejandro; Mylonakis, Eleftherios

2013-01-01

Fusarium is a fungal pathogen of immunosuppressed lung transplant patients associated with a high mortality in those with severe and persistent neutropenia. The principle portal of entry for Fusarium species is the airways, and lung involvement almost always occurs among lung transplant patients with disseminated infection. In these patients, the immunoprotective mechanisms of the transplanted lungs are impaired, and they are, therefore, more vulnerable to Fusarium infection. As a result, fusariosis occurs in up to 32% of lung transplant patients. We studied fusariosis in 6 patients following lung transplantation who were treated at Massachusetts General Hospital during an 8-year period and reviewed 3 published cases in the literature. Cases were identified by the microbiology laboratory and through discharge summaries. Patients presented with dyspnea, fever, nonproductive cough, hemoptysis, and headache. Blood tests showed elevated white blood cell counts with granulocytosis and elevated inflammatory markers. Cultures of Fusarium were isolated from bronchoalveolar lavage, blood, and sputum specimens. Treatments included amphotericin B, liposomal amphotericin B, caspofungin, voriconazole, and posaconazole, either alone or in combination. Lung involvement occurred in all patients with disseminated disease and it was associated with a poor outcome. The mortality rate in this group of patients was high (67%), and of those who survived, 1 patient was treated with a combination of amphotericin B and voriconazole, 1 patient with amphotericin B, and 1 patient with posaconazole. Recommended empirical treatment includes voriconazole, amphotericin B or liposomal amphotericin B first-line, and posaconazole for refractory disease. High-dose amphotericin B is recommended for treatment of most cases of fusariosis. The echinocandins (for example, caspofungin, micafungin, anidulafungin) are generally avoided because Fusarium species have intrinsic resistance to them. Treatment should ideally be based on the Fusarium isolate, susceptibility testing, and host-specific factors. Prognosis of fusariosis in the immunocompromised is directly related to a patient’s immune status. Prevention of Fusarium infection is recommended with aerosolized amphotericin B deoxycholate, which also has activity against other important fungi. PMID:21200188

Bacillus Calmette-Guërin--a live, attenuated strain of Mycobacterium bovis has been used in immunotherapy of patients with superficial urinary bladder carcinoma. Some patients develop complications after intravesical instillation of BCG: high temperature followed by hematuria or granulomatous prostatits, epidydimoorchitis, urethral obstruction, and less than 1% have a systemic disease followed by dissemination of bacteria into other organs. A 50-year-old man underwent transurethral resection of a bladder tumor. One month after the operation BCG intravesical installations were administered for three weeks. After the fourth installation, our patient developed high fever, fatigue, vomiting, dark urine, light stools, and jaundice. On admission he was jaundiced with a high fever, enlarged liver and spleen and laboratory findings which included high erythrocyte sedimentation rate, pancytopenia, elevated liver enzymes, especially alkaline phosphatase and aminotranspherases. The bone-marrow biopsy showed granulomatous inflamation suggesting mycobacterial spread in the bone marrow, liver and spleen and sepsis. The patient was initially treated with antituberculous therapy, but his state did not improve until corticosteroids were added to the antituberculous treatment regimen. Although dissemination of BCG is a rare complication of intravesical BCG treatment of the bladder carcinoma, it may result in prolonged fever and granulomatous inflamation of the liver, spleen, lungs, bone marrow and BCG sepsis. Antituberclous agents in combination with corticosteroids comprise the treatment of choice for disseminated BCG infection.

Little is known about the relationship between body temperature and outcomes in patients with acute respiratory distress syndrome (ARDS). A better understanding of this relationship may provide evidence for fever suppression or warming interventions, which are commonly applied in practice. To examine the relationship between body temperature and mortality in patients with ARDS. Secondary analysis of body temperature and mortality using data from the ARDS Network Fluid and Catheter Treatment Trial (n = 969). Body temperature at baseline and on study day 2, primary cause of ARDS, severity of illness, and 90-day mortality were analyzed by using multiple logistic regression. Mean baseline temperature was 37.5°C (SD, 1.1°C; range, 27.2°C-40.7°C). At baseline, fever (≥ 38.3°C) was present in 23% and hypothermia (< 36°C) in 5% of the patients. Body temperature was a significant predictor of 90-day mortality after primary cause of ARDS and score on the Acute Physiology and Chronic Health Evaluation III were adjusted for. Higher temperature was associated with decreased mortality: for every 1°C increase in baseline temperature, the odds of death decreased by 15% (odds ratio, 0.85; 95% CI, 0.73-0.98, P = .03). When patients were divided into 5 temperature groups, mortality was lower with higher temperature (P for trend = .02). Early in ARDS, fever is associated with improved survival rates. Fever in the acute phase response to lung injury and its relationship to recovery may be an important factor in determining patients' outcome and warrants further study. ©2015 American Association of Critical-Care Nurses.

Studies on scarlet fever with meteorological factors included were few. We aimed to illustrate meteorological factors' effects on monthly incidence of scarlet fever. Cases of scarlet fever were collected from the report of legal infectious disease in Hefei City from 1985 to 2006; the meteorological data were obtained from the weather bureau of Hefei City. Monthly incidence and corresponding meteorological data in these 22 years were used to develop the model. The model of auto regressive integrated moving average with covariates was used in statistical analyses. There was a highest peak from March to June and a small peak from November to January. The incidence of scarlet fever ranges from 0 to 0.71502 (per 105 population). SARIMAX (1,0,0)(1,0,0)12 model was fitted with monthly incidence and meteorological data optimally. It was shown that relative humidity ( β = -0.002, p = 0.020), mean temperature ( β = 0.006, p = 0.004), and 1 month lag minimum temperature ( β = -0.007, p < 0.001) had effect on the incidence of scarlet fever in Hefei. Besides, the incidence in a previous month (AR( β) = 0.469, p < 0.001) and in 12 months before (SAR( β) = 0.255, p < 0.001) was positively associated with the incidence. This study shows that scarlet fever incidence was negatively associated with monthly minimum temperature and relative humidity while was positively associated with mean temperature in Hefei City, China. Besides, the ARIMA model could be useful not only for prediction but also for the analysis of multiple correlations.

Lassa virus (LASV) infection causes an acute, multisystemic viral hemorrhagic fever that annually infects an estimated 100 000 to 300 000 persons in West Africa. This pathogenesis study evaluated the temporal progression of disease in guinea pigs following aerosol and subcutaneous inoculation of the Josiah strain of LASV as well as the usefulness of Strain 13 guinea pigs as an animal model for Lassa fever. After experimental infection, guinea pigs ( Cavia porcellus; n = 67) were serially sampled to evaluate the temporal progression of infection, gross and histologic lesions, and serum chemistry and hematologic changes. Guinea pigs developed viremia on day 5 to 6 postexposure (PE), with clinical signs appearing by day 7 to 8 PE. Complete blood counts revealed lymphopenia and thrombocytopenia. Gross pathologic findings included skin lesions and congested lungs. Histologic lesions consisted of cortical lymphoid depletion by day 6 to 7 PE with lymphohistiocytic interstitial pneumonia at 7 to 8 days PE. Scattered hepatocellular degeneration and cell death were also noted in the liver and, to a lesser extent, in other tissues including the haired skin, lung, heart, adrenal gland, lymph nodes, thymus, and spleen. The first cell types to demonstrate staining for viral antigen were fibroblastic reticular cells and macrophages/dendritic cells in the lymph nodes on day 5 to 6 PE. This study demonstrates similarities between Lassa viral disease in human infections and experimental guinea pig infection. These shared pathologic characteristics support the utility of guinea pigs as an additional animal model for vaccine and therapeutic development under the Food and Drug Administration's Animal Rule.

Background Rocky Mountain spotted fever (RMSF) is a disease that now causes significant morbidity and mortality on several American Indian reservations in Arizona. Although the disease is treatable, reported RMSF case fatality rates from this region are high (7%) compared to the rest of the nation (<1%), suggesting a need to identify clinical points for intervention. Methods The first 205 cases from this region were reviewed and fatal RMSF cases were compared to nonfatal cases to determine clinical risk factors for fatal outcome. Results Doxycycline was initiated significantly later in fatal cases (median, day 7) than nonfatal cases (median, day 3), although both groups of case patients presented for care early (median, day 2). Multiple factors increased the risk of doxycycline delay and fatal outcome, such as early symptoms of nausea and diarrhea, history of alcoholism or chronic lung disease, and abnormal laboratory results such as elevated liver aminotransferases. Rash, history of tick bite, thrombocytopenia, and hyponatremia were often absent at initial presentation. Conclusions Earlier treatment with doxycycline can decrease morbidity and mortality from RMSF in this region. Recognition of risk factors associated with doxycycline delay and fatal outcome, such as early gastrointestinal symptoms and a history of alcoholism or chronic lung disease, may be useful in guiding early treatment decisions. Healthcare providers should have a low threshold for initiating doxycycline whenever treating febrile or potentially septic patients from tribal lands in Arizona, even if an alternative diagnosis seems more likely and classic findings of RMSF are absent.

Hemorrhagic fever with renal syndrome (HFRS) is an important infectious disease in Hebei Province. At present, cases from the northeast regions of the province account for >80% of the total incidences. However, studies that examine the region-specific genetic variations of the Hantavirus (HV), the causative pathogen for HFRS, have been lacking. Rodents were collected in northeast Hebei Province from 2004 to 2013, and the HV strains used in this study were isolated in 1993. Lung tissues were isolated from the rodents and HV antigen was detected by indirect immunofluorescence. The M1 and M2 fragments of HV M region were amplified by reverse transcription polymerase chain reaction (RT-PCR), cloned into pMDl9-T vector, sequenced and compared with representative standard stains for homology and phylogenetic analysis. A total of 21 samples of HV antigen-positive were collected. Real-time PCR analysis revealed that the 19 rodent lungs and two HV strains were positive for the SEO virus. 11 samples were chosen to sequence, and they shared 95.8%-99.8% in nucleotide homology, and 83.6%-99.2% when compared to the standard strains of SEO virus. Phylogenetic analysis demonstrated that all strains were grouped into the same S3 subtype. SEO was the major epidemic genotype of HV in the main HFRS endemic areas in Hebei Province, and S3 was the major subtype. There was minor genetic variation in HV over short term periods, while long term variations were higher.

Coxiella burnetii, the causative agent of Q fever, survives and replicates in the acidic environment of monocytes/macrophages; hydroxychloroquine, through alkalinisation of the acidic vacuoles, is critical for the management of Q fever. In this study, a collection of C. burnetii strains isolated from human samples was tested to evaluate the in vitro minimum inhibitory concentrations (MICs) of doxycycline and hydroxychloroquine. Serial two-fold dilutions of doxycycline (0.25-8 mg/L) and hydroxychloroquine (0.25-4 mg/L) were added to C. burnetii-infected human embryonic lung (HEL) fibroblast cells after 48 h of incubation, in duplicate. DNA was detected by C. burnetii-specific semi-quantitative PCR with primers and probes designed for amplification of the IS1111 and IS30A spacers. A total of 29 C. burnetii isolates obtained from 29 patients were tested. Doxycycline MICs ranged from 0.25 mg/L to 0.5 mg/L and hydroxychloroquine MICs from 0.25 mg/L to >4 mg/L. Four C. burnetii stains had hydroxychloroquine MICs ≤ 1 mg/L. The concentration of hydroxychloroquine was associated with a significant decrease in C. burnetii DNA copies in HEL cells based on linear regression analysis (P= 0.01). Recommended serum concentrations of hydroxychloroquine significantly reduced the growth of C. burnetii. Moreover, some C. burnetii strains presented hydroxychloroquine MICs below the recommended serum concentrations, indicating that, for these cases, hydroxychloroquine treatment alone may even be effective.

To describe a case of small retinal vessel vasculopathy postvaccination. We report the case of a 41-year-old white man who presented with a "second blind spot," describing a nasal scotoma in the right eye that started 4 days after vaccinations against Neisseria meningitidis and the yellow fever virus, and after a 2-month period of high stress and decreased sleep. Clinical examination, Humphrey visual field testing, and multimodal imaging with fundus photographs, autofluorescence, fluorescein angiography, and spectral domain optical coherence tomography and angiography were performed. Clinical examination revealed a well-circumscribed, triangular area of retinal graying of about 1-disk diameter in size, located at the border of the temporal macula. This corresponded to a deep scotoma similar in size to the physiologic blind spot on Humphrey visual field 24-2 testing. There was mild hypoautofluoresence of this lesion on autofluorescence, hypofluorescence on fluorescein angiography, and focal attenuation of a small artery just distal to the bifurcation of an artery supplying the involved area. Spectral domain optical coherence tomography through the lesion conveyed hyperreflectivity most prominent in the inner and outer plexiform layers, with extension of the hyperreflectivity into the ganglion cell and inner nuclear layers. Spectral domain optical coherence tomography angiography demonstrated arteriolar and capillary dropout, more pronounced in the superficial retinal layer compared to the deeper retinal layer. At 1-month follow-up, his scotoma improved with monitoring, with reduction from -32 dB to -7 dB on Humphrey visual field testing. There was clinical resolution of the area of graying and decreased hyperreflectivity on spectral domain optical coherence tomography, with atrophy of the inner retina. Spectral domain optical coherence tomography angiography showed progression of arteriolar and capillary dropout, more so in the superficial than in the deep capillary plexus. We describe a case of small artery occlusion in a previously healthy patient, 4 days after vaccination against N. meningitidis and yellow fever. Fluorescein angiography yielded greater diagnostic value than OCTA for evaluating the occlusion, whereas spectral domain optical coherence tomography angiography enabled better visualization of capillary dropout and layer-specific assessment. Further research is required to determine whether vaccination in general, or directed specifically at N. meningitidis or yellow fever, is associated with small vessel vasculopathy and the underlying pathogenesis.

2017-01-01

The treatment paradigm for metastatic non-small cell, non-squamous lung cancer is continuously evolving due to new treatment options and our increasing knowledge of molecular signal pathways. As a result of treatments becoming more efficacious and more personalized, survival for selected groups of non-small cell lung cancer (NSCLC) patients is increasing. In this paper, three algorithms will be presented for treating patients with metastatic non-squamous, NSCLC. These include treatment algorithms for NSCLC patients whose tumors have EGFR mutations, ALK rearrangements, or wild-type/wild-type tumors. As the world of immunotherapy continues to evolve quickly, a future algorithm will also be presented. PMID:28373963

Non-small-cell lung cancer (NSCLC) is a leading cause of cancer deaths worldwide. Crizotinib has been approved by the U.S. Food and Drug Administration for the treatment of patients with advanced NSCLC. However, understanding of mechanisms of action is still limited. In our studies, we confirmed crizotinib-induced apoptosis in A549 lung cancer cells. In order to assess mechanisms, small molecular docking technology was used as a preliminary simulation of signaling pathways. Interesting, our results of experiments were consistent with the results of computer simulation. This indicates that small molecular docking technology should find wide use for its reliability and convenience.

Background We aimed to clarify that the size of the lung adenocarcinoma evaluated using mediastinal window on computed tomography is an important and useful modality for predicting invasiveness, lymph node metastasis and prognosis in small adenocarcinoma. Methods We evaluated 176 patients with small lung adenocarcinomas (diameter, 1–3 cm) who underwent standard surgical resection. Tumours were examined using computed tomography with thin section conditions (1.25 mm thick on high-resolution computed tomography) with tumour dimensions evaluated under two settings: lung window and mediastinal window. We also determined the patient age, gender, preoperative nodal status, tumour size, tumour disappearance ratio, preoperative serum carcinoembryonic antigen levels and pathological status (lymphatic vessel, vascular vessel or pleural invasion). Recurrence-free survival was used for prognosis. Results Lung window, mediastinal window, tumour disappearance ratio and preoperative nodal status were significant predictive factors for recurrence-free survival in univariate analyses. Areas under the receiver operator curves for recurrence were 0.76, 0.73 and 0.65 for mediastinal window, tumour disappearance ratio and lung window, respectively. Lung window, mediastinal window, tumour disappearance ratio, preoperative serum carcinoembryonic antigen levels and preoperative nodal status were significant predictive factors for lymph node metastasis in univariate analyses; areas under the receiver operator curves were 0.61, 0.76, 0.72 and 0.66, for lung window, mediastinal window, tumour disappearance ratio and preoperative serum carcinoembryonic antigen levels, respectively. Lung window, mediastinal window, tumour disappearance ratio, preoperative serum carcinoembryonic antigen levels and preoperative nodal status were significant factors for lymphatic vessel, vascular vessel or pleural invasion in univariate analyses; areas under the receiver operator curves were 0.60, 0.81, 0.81 and 0.65 for lung window, mediastinal window, tumour disappearance ratio and preoperative serum carcinoembryonic antigen levels, respectively. Conclusions According to the univariate analyses including a logistic regression and ROCs performed for variables with p-values of <0.05 on univariate analyses, our results suggest that measuring tumour size using mediastinal window on high-resolution computed tomography is a simple and useful preoperative prognosis modality in small adenocarcinoma.

The tumor microenvironment orchestrates the sustained growth, metastasis and recurrence of cancer. As an indispensable component of the tumor microenvironment, cancer-associated fibroblasts (CAF) are considered as an essential synthetic machine producing various tumor components, leading to cancer sustained stemness, drug resistance and tumor recurrence. Here, we developed a sustainable primary culture of lung cancer cells fed with lung cancer-associated fibroblasts, resulting in enrichment and acquisition of drug resistance in cancer cells. Moreover, IGF2/AKT/Sox2/ABCB1 signaling activation in cancer cells was observed in the presence of CAF, which induces upregulation of P-glycoprotein expression and the drug resistance of non-small cell lung cancer cells. Our results demonstrated that CAF cells constitute a mechanism for cancer drug resistance. Thus, traditional chemotherapy combined with insulin-like growth factor 2 (IGF2) signaling inhibitor may present an innovative therapeutic strategy for non-small cell lung cancer therapy. © 2018 The Authors.

Highlights: • MiR-429 expression is upregulated in non-small cell lung cancer (NSCLC). • MiR-429 inhibits PTEN, RASSF8 and TIMP2 expression. • MiR-429 promotes metastasis and proliferation. • We report important regulatory mechanisms involved in NSCLC progression. • MiR-429 is a potential therapeutic target and diagnostic marker. - Abstract: Lung cancer is the major cause of cancer death globally. MicroRNAs are evolutionally conserved small noncoding RNAs that are critical for the regulation of gene expression. Aberrant expression of microRNA (miRNA) has been implicated in cancer initiation and progression. In this study, we demonstrated that the expression of miR-429 are often upregulatedmore » in non-small cell lung cancer (NSCLC) compared with normal lung tissues, and its expression level is also increased in NSCLC cell lines compared with normal lung cells. Overexpression of miR-429 in A549 NSCLC cells significantly promoted cell proliferation, migration and invasion, whereas inhibition of miR-429 inhibits these effects. Furthermore, we demonstrated that miR-429 down-regulates PTEN, RASSF8 and TIMP2 expression by directly targeting the 3′-untranslated region of these target genes. Taken together, our results suggest that miR-429 plays an important role in promoting the proliferation and metastasis of NSCLC cells and is a potential target for NSCLC therapy.« less

It has been recognized that patients with non-small cell lung cancer who are lifelong never-smokers constitute a distinct clinical entity. The aim of this study was to assess clinical risk factors for survival among never-smokers with non-small cell lung cancer. All consecutive non-small cell lung cancer patients diagnosed (n = 285) between May 2005 and May 2009 were included. The clinical characteristics of never-smokers and ever-smokers (former and current) were compared using chi-squared or Student's t tests. Survival curves were calculated using the Kaplan-Meier method, and log-rank tests were used for survival comparisons. A Cox proportional hazards regression analysis was evaluated by adjusting for age (continuous variable), gender (female vs. male), smoking status (never- vs. ever-smoker), the Karnofsky Performance Status Scale (continuous variable), histological type (adenocarcinoma vs. non-adenocarcinoma), AJCC staging (early vs. advanced staging), and treatment (chemotherapy and/or radiotherapy vs. the best treatment support). Of the 285 non-small cell lung cancer patients, 56 patients were never-smokers. Univariate analyses indicated that the never-smoker patients were more likely to be female (68% vs. 32%) and have adenocarcinoma (70% vs. 51%). Overall median survival was 15.7 months (95% CI: 13.2 to 18.2). The never-smoker patients had a better survival rate than their counterpart, the ever-smokers. Never-smoker status, higher Karnofsky Performance Status, early staging, and treatment were independent and favorable prognostic factors for survival after adjusting for age, gender, and adenocarcinoma in multivariate analysis. Epidemiological differences exist between never- and ever-smokers with lung cancer. Overall survival among never-smokers was found to be higher and independent of gender and histological type.

Though glycyrrhetinic acid (GA) from Glycyrrhiza glabra was known to exert antioxidant, antifilarial, hepatoprotective, anti-inflammatory and anti-tumor effects, the antitumor mechanism of GA was not clearly elucidated in non-small cell lung cancer cells (NSCLCCs). Thus, in the present study, the underlying apoptotic mechanism of GA was examined in NCI-H460 NSCLCCs. GA significantly suppressed the viability of NCI-H460 and A549 non-small lung cancer cells. Also, GA significantly increased the sub G1 population by cell cycle analysis and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) positive cells in a concentration dependent manner in NCI-H460 non-small lung cancer cells. Consistently, GA cleaved poly (ADP-ribosyl) polymerase (PARP), caspase 9/3, attenuated the expression of Bcl-XL, Bcl-2, Cyclin D1 and Cyclin E in NCI-H460 cells. Interestingly, GA attenuated the phosphorylation of protein kinase C (PKC) α/βII and extracellular activated protein kinase (ERK) as well as activated the phosphorylation of PKC δ and c-Jun NH2-terminal kinase in NCI-H460 cells. Conversely, PKC promoter phorbol 12-myristate 13-acetate (PMA) and JNK inhibitor SP600125 reversed the cleavages of caspase 3 and PARP induced by GA in NCI-H460 cells. Overall, our findings suggest that GA induces apoptosis via inhibition of PKC α/βII and activation of JNK in NCI-H460 non-small lung cancer cells as a potent anticancer candidate for lung cancer treatment.

Bevacizumab(Avastin(®) ), a humanized therapeutic monoclonal antibody that targets vascular endothelial growth factor, is widely used in cancer treatment. Patients who are treated with bevacizumab have an increased risk of developing systemic hypertension. However, the relationship between bevacizumab-induced hypertension and clinical outcome remains unclear. We aimed to evaluate the effect of bevacizumab-induced hypertension in terms of prognosis in patients with colorectal cancer and non-small cell lung cancer. The study included 632 patients, 317 patients with non-small cell lung cancer and 315 patients with colorectal cancer. All patients were treated with bevacizumab in combination with standard chemotherapy protocols, between April 2007 and December 2014. Blood pressure was measured before each treatment cycle. In the patient group with colorectal cancer, treated with bevacizumab, Grade 2-3 hypertension was present in 27.6%. In hypertensive patients with colorectal cancer, median overall survival was 42.6 months, compared with 20.6 months for normotensive patients in this group (P = 0.00071). In the patient group with non-small cell lung cancer, treated with bevacizumab, Grade 2-3 hypertension was present in 20.5%. In hypertensive patients with non-small cell lung cancer, median overall survival was 43.0 months, compared with 26.3 months for normotensive patients in this group (P = 0.00451). Patients who developed hypertension during treatment with bevacizumab for colorectal cancer and non-small cell lung cancer had significantly prolonged overall survival when compared with normotensive patients. Bevacizumab-induced hypertension may represent a biomarker for clinical benefit in cancer patients treated with bevacizumab. © 2016 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

The 3He lung morphometry technique, based on MRI measurements of hyperpolarized 3He gas diffusion in lung airspaces, provides unique information on the lung microstructure at the alveolar level. In vivo 3D tomographic images of standard morphological parameters (airspace chord length, lung parenchyma surface-to-volume ratio, number of alveoli per unit volume) can be generated from a rather short (several seconds) MRI scan. The technique is based on a theory of gas diffusion in lung acinar airways and experimental measurements of diffusion attenuated MRI signal. The present work aims at developing the theoretical background of a similar technique based on hyperpolarized 129Xe gas. As the diffusion coefficient and gyromagnetic ratio of 129Xe gas are substantially different from those of 3He gas, the specific details of the theory and experimental measurements with 129Xe should be amended. We establish phenomenological relationships between acinar airway geometrical parameters and the diffusion attenuated MR signal for human and small animal lungs, both normal lungs and lungs with mild emphysema. Optimal diffusion times are shown to be about 5 ms for human and 1.3 ms for small animals. The expected uncertainties in measuring main morphometrical parameters of the lungs are estimated in the framework of Bayesian probability theory. PMID:21713985
