COVID-19: vaccination vs. hospitalization.

OBJECTIVE: Vaccination is the most efficient way to control the coronavirus disease 2019 (COVID-19) pandemic, but vaccination rates remain below the target level in most countries. This multicenter study aimed to evaluate the vaccination status of hospitalized patients and compare two different booster vaccine protocols. SETTING: Inoculation in Turkey began in mid-January 2021. Sinovac was the only available vaccine until April 2021, when BioNTech was added. At the beginning of July 2021, the government offered a third booster dose to healthcare workers and people aged > 50 years who had received the two doses of Sinovac. Of the participants who received a booster, most chose BioNTech as the third dose. METHODS: We collected data from 25 hospitals in 16 cities. Patients hospitalized between August 1 and 10, 2021, were included and categorized into eight groups according to their vaccination status. RESULTS: We identified 1401 patients, of which 529 (37.7%) were admitted to intensive care units. Nearly half (47.8%) of the patients were not vaccinated, and those with two doses of Sinovac formed the second largest group (32.9%). Hospitalizations were lower in the group which received 2 doses of Sinovac and a booster dose of BioNTech than in the group which received 3 doses of Sinovac. CONCLUSION: Effective vaccinations decreased COVID-19-related hospitalizations. The efficacy after two doses of Sinovac may decrease over time; however, it may be enhanced by adding a booster dose. Moreover, unvaccinated patients may be persuaded to undergo vaccination.

Low-dose thrombolysis for submassive pulmonary embolism.

The role of thrombolysis in submassive pulmonary embolism (PE) is controversial due to the high risk of hemorrhage. This study aimed to evaluate the role of half-dose tissue-type plasminogen activator (rt-PA) in preventing death/hemodynamic decompensation in submassive (intermediate-risk) PE without increasing the risk of bleeding. In a prospective, non-randomized, open-label, single-center trial, we compared 50 mg rt-PA plus low molecular weight heparin (LMWH) with LMWH in submassive (intermediate-risk) PE. Eligible cases had confirmed pulmonary hypertension on echocardiography, and/or right ventricular cavity expansion and/or interventricular septal deviation on echocardiography, and/or right to left ventricular ratio equal to or greater than 0.9 mm on CT angiography. The primary outcome was death or hemodynamic decompensation within 7 and 30 days after treatment was given. The primary safety outcome was major extracranial bleeding or hemorrhagic stroke within 7 days. Seventy-six patients were included in the study. Total death/hemodynamic decompensation in the first 7 and 30 days was significantly less in the half-dose rt-PA group than in the LMWH group (p=0.028 and p=0.009, respectively). No significant differences were found between the two groups in terms of recurrent embolism and pulmonary hypertension at 6-month follow-up (p=1.000 and p=0.778). There was no intracranial hemorrhage in any of the patients. There were no statistically significant differences between the two groups in terms of major or minor bleeding complications. This trial showed half-dose rt-PA treatment in submassive (intermediate-risk) PE prevented death/hemodynamic decompensation in the first 7-day and 30-day period compared with LMWH treatment without increasing the risk of bleeding.

Survey of Physician's Knowledge, Attitudes, and Practices Regarding Idiopathic Pulmonary Fibrosis in Turkey.

OBJECTIVES: The aim of this study is to evaluate the approaches of Turkish pulmonologists to the diagnosis and treatment of idiopathic pulmonary fibrosis (IPF) in daily clinical practice. MATERIALS AND METHODS: A questionnaire containing 38 questions about the IPF diagnosis and treatment was given to pulmonologists between January 22 and 29, 2018, and the data of 158 physicians who responded to the questionnaire were evaluated. RESULTS: This survey showed that the mean number of patients that physicians followed up and managed annually was 8.3 and 5, respectively. The mean symptom duration before the diagnosis was 9-12 months. Patients were seen on average by three physicians prior to confirmed diagnosis. Almost 80% of the physicians have an opportunity to access a pathologist and radiologist specialized in IPF. However, only 26% of them have an opportunity to access regular multidisciplinary meetings. Although antifibrotics were the most commonly prescribed drugs, approximately 10% of patients were prescribed steroids, N-acetylcysteine, and immunosuppressants. Most of the physicians (81%) were aware of international guidelines; however, the Turkish Thoracic Society IPF Diagnosis and Treatment Consensus Report was read by only 41% of them. CONCLUSION: This survey may lead to the IPF awareness in Turkey, and it may help to close the gaps regarding the diagnosis and treatment.

Tracheobronchial Amyloidosis Mimicking Tracheal Tumor.

Tracheobronchial amyloidosis is a rare presentation and accounts for about 1% of benign tumors in this area. The diagnosis of disease is delayed due to nonspecific pulmonary symptoms. Therapeutic approaches are required to control progressive pulmonary symptoms for most of the patients. Herein, we report a case of a 68-year-old man admitted with progressive dyspnea to our institution for further evaluation and management. He was initially diagnosed with and underwent management for bronchial asthma for two years but had persistent symptoms despite optimal medical therapy. Pulmonary computed tomography scan revealed severe endotracheal stenosis. Bronchoscopy was performed and showed endotracheal mass obstructing 70% of the distal trachea and mimicking a neoplastic lesion. The mass was successfully resected by mechanical resection, argon plasma coagulation (APC), and Nd-YAG laser during rigid bronchoscopy. Biopsy materials showed deposits of amorphous material by hematoxylin and eosin staining and these deposits were selectively stained with Congo Red. Although this is a rare clinical condition, this case indicated that carrying out a bronchoscopy in any patient complaining of atypical bronchial symptoms or with uncontrolled asthma is very important.

Psychological complaints reported by sexually abused children during criminal investigations: Istanbul example.

The present study aims at describing the psychological complaints reported, as a part of the criminal investigation process, by the victims of sexual abuse as a part of the criminal investigation process, without attempting at reaching a medical diagnosis; and it discusses the relation of these reports with variables such as victim's gender, age and relation to the offender, type and duration of abuse, and parental marital status of the victim. Data is obtained from the statements of childhood sexual abuse (CSA) victims under the age of 15, as taken by Istanbul Juvenile Justice Department between the years 2009 and 2012. The sample consists of 175 cases with a total of 202 victim statements. Through the use of content analysis, the main and sub-categories of themes of the statements were determined. By means of the evaluation of the psychological condition of victims, we evaluated them in two categories: psychological complaints including self-harm and risk taking behaviors and psychological complaints with no self-harm and risk taking behaviors. The statistical analyses yield significant relations between the psychological complaints and children's parental marital status. Analysis of initial statements of sexual abuse victims is important as it may greatly contribute to professionals diagnosing and treating psychological complaints of these victims. It is essential that victims of sexual abuse should receive immediate psychological support starting with the criminal investigation process.

[Treatment and diagnosis of pulmonary embolism in pregnancy]. / Gebelerde pulmoner tromboembolinin tani ve tedavisi.

When occurring during pregnancy, venous thrombo-embolism is a major cause of maternal mortality. The risk is highest in the third trimester of pregnancy and over the 6 weeks of the postpartum period. Exposure of the foetus to ionizing radiation is a concern when investigating suspected PE during pregnancy; although this concern is largely overruled by the hazards of missing a potentially fatal diagnosis. This is particularly true for pregnant patients with suspected high risk. A normal D-dimer value has the same exclusion value for PE in pregnant women as for other patients with suspected PE but is found more rarely, because plasma D-dimer levels physiologically increase throughout pregnancy. In pregnant women with suspected PE and signs and symptoms of DVT, guidelines suggest performing bilateral compression ultrasound of lower extremities. Use of lung scintigraphy as the preferred test in the setting of a normal CXR. The treatment of PE in pregnancy is based on heparin anticoagulation. Increasing experience suggests that LMWHs are safe in pregnancy, and their use is endorsed in several reports. Treatment should consist of a weight-adjusted dose of LMWH.

Tratamiento efectivo de la hemoptisis mediante aplicación endobronquial del hemostásico Ankaferd / Effective Management of Hemoptysis Via Endobronchial Application of Ankaferd Hemostat

La hemoptisis es una manifestación sintomática de una enfermedad torácica que puede ser grave y poner en peligro la vida, y requiere una evaluación y tratamiento urgentes. El objetivo del presente estudio fue evaluar la eficacia hemostásica de la aplicación endobronquial de la solución Ankaferd Blood Stopper(R) (ABS) en pacientes con hemoptisis. Este estudio retrospectivo se realizó en 20 pacientes con hemoptisis en los que se aplicó ABS endobronquial mediante 25 broncoscopias. La aplicación endobronquial de ABS tuvo éxito en 23 de las 25 broncoscopias. Se repitió la aplicación de ABS a causa de una recidiva hemorrágica en 4 pacientes. Esta es la primera serie de casos que describe el uso de la aplicación endobronquial de ABS, un nuevo agente hemostásico que constituye un método eficaz para el tratamiento de la hemorragia, sobre todo en lesiones malignas endobronquiales locales. Pensamos que la aplicación broncoscópica de ABS puede ser un método terapéutico alternativo y de apoyo en casos de hemoptisis no controlada

Massive hemoptysis due to welding fumes.

Many pulmonary problems such as lung cancer, occupational asthma, and pneumoconiosis have been described due to welding in the literature until now. This is the first case report of alveolar hemorrhage due to welding fumes presented with massive hemoptysis. We report a rare case of massive hemopthisis associated with welder's lung, with a discussion based on a review of the literature. ESTABLISHED FACTS: Many pulmonary diseases such as lung cancer, occupational asthma, and pneumoconiosis have been attributed welding fumes in the literature. Alveolar hemorrhage due to welding fumes has never defined before. NOVEL INSIGHTS: We herein report a case of alveolar hemorrhage presented with massive hemoptysis due to welding fumes. Clinicians should be aware of such rare but serious clinical picture which can occur in welding workers. Palliative measures and bronchoscopic Ankaferd Blood Stopper(®) application may help to stop bleeding.

Clinical presentations and diagnostic work-up in sarcoidosis: a series of Turkish cases (clinics and diagnosis of sarcoidosis).

Sarcoidosis is an idiopathic granulomatous disease. It usually affects the lung. The diagnosis may be problematic since the known causes of granulomatous inflammation must be excluded. This multicenter study aimed to evaluate the clinical presentations and diagnostic approaches of sarcoidosis. The study protocol was sent via internet, and the participants were asked to send the information (clinical, radiological and diagnostic) on newly diagnosed sarcoidosis cases. 293 patients were enrolled within two years. Pulmonary symptoms were found in 73.3% of the patients, and cough was the most common one (53.2%), followed by dyspnea (40.3%). Constitutional symptoms were occured in half of the patients. The most common one was fatigue (38.6%). The most common physical sign was eritema nodosum (17.1%). The most common chest radiograhical sign was bilateral hilar lymphadenomegaly (78.8%). Staging according to chest X-ray has revealed that most of the patients were in Stage I and Stage II (51.9% and 31.7%, respectively). Sarcoidosis was confirmed histopathologically in 265 (90.4%) patients. Although one-third of the bronchoscopy was revealed normal, mucosal hyperemi (19.8%) and external compression of the bronchial wall (16.8%) were common abnormal findings. The 100% success rate was obtained in mediastinoscopy among the frequently used sampling methods. Transbronchial biopsy was the most frequently used method with 48.8% success rate. Considering sarcoidosis with its most common and also rare findings in the differential diagnosis, organizing the related procedures according to the possibly effected areas, and the expertise of the team would favour multimodality diagnosis.

The prevalence of "pigeon breeder's disease" in a Turkish city and review of the literature.

Hypersensitivity pneumonitis (HP) is a rarely encountered inflammatory interstitial lung disease caused by various antigens. Studies in the literature report contradictory rates about its prevalence. The aim of the present study was to determine the prevalence of "pigeon breeder's disease" (PBD) among pigeon breeders in Samsun province. The present study was performed in two phases. In the first phase, we contacted the Samsun Serinofil Association (Samsun Serinofil Dernegi) and a detailed questionnaire was given to the pigeon breeders to fill out. In the second phase, advanced diagnostic tests such as chest X-ray, high-resolution chest computed tomography, pulmonary function tests, natural provocation, bronchoalveolar lavage (BAL), and transbronchial lung biopsy (TBLB) were used to verify the diagnosis in those suspected with PBL. The questionnaire was administered to 185 male volunteers, of whom 11 had suspicious findings. Of eight subjects in whom the natural provocation was performed, one had a positive (acute PBL) response. After discontinuation of exposure, clinical improvement was observed in the second subject (subacute HP), of whom the radiological findings, BAL, and TBLB results were consistent with PBL. The third subject, who had dyspnea for 28 years, was diagnosed with chronic PBL. Consequently, the prevalence of PBL and the positivity of the natural provocation were 1.6 and 12.5%, respectively. In the present study, in which the prevalence of PBL was determined using natural provocation for the first time, the prevalence of HP (1.6%) was quite low compared with previous studies. The present study has demonstrated that a study solely based on a questionnaire is not adequate in determining the prevalence of HP.

Extrapulmonary involvement in patients with sarcoidosis in Turkey.

BACKGROUND AND OBJECTIVE: Extrapulmonary sarcoidosis is common, and is almost always associated with concomitant thoracic involvement. Extrapulmonary manifestations vary on the basis of gender, age at presentation and ethnicity. The aim of this study was to investigate extrapulmonary involvement in patients with sarcoidosis in Turkey. METHODS: This study was conducted by Turkish Thoracic Society Clinical Problems Study Group. New cases of sarcoidosis between 1 June 2004 and 31 May 2006 were recorded on electronic case record forms sent to all potential investigators and information about extrapulmonary involvement was collected. RESULTS: One hundred and nineteen of 293 patients (83 female, 36 male, mean age = 45 ± 12 years) had extrapulmonary involvement in this study (40.6%). The median time to diagnosis was 6 months and this was longer than patients with just thoracic sarcoidosis (P = 0.001). Extrapulmonary symptoms were present in 181 (61.8%) patients, and skin lesions, arthralgia and back pain were the commonest (33.4%, 20.8% and 16.4%, respectively). Incidence of organ involvement was independent of age with the exception of ocular involvement, which was higher in those under the age of 40 years (P = 0.007). CONCLUSIONS: Skin and peripheral lymph node involvement were the most common sites of extrapulmonary involvement and ocular involvement was more common in those under the age of 40 years in patients with sarcoidosis in a Turkish population.

A prospective evaluation of hemoptysis cases in a tertiary referral hospital.

BACKGROUND AND AIMS: Hemoptysis is symptomatic of a potentially serious and life-threatening thoracic disease. The purpose of this study was to evaluate the relative frequency of the different causes of hemoptysis, the change of the frequency of diseases, the value of the evaluation process and the outcome in a tertiary referral hospital. METHODS: A prospective study was carried out on consecutive patients presented with hemoptysis. RESULTS: A total of 178 patients (136 male, 42 female) were included to the study. Lung cancer (51), pulmonary embolism (23) and bronchiectasis (23) constituted most of the diagnosis. The most frequent cause of hemoptysis in males was by far lung carcinoma (50). Twelve cases of bronchiectasis and 11 cases of pulmonary embolism were observed in females. While lung cancer and pulmonary embolism were associated with mild to moderate amounts of bleeding (84% and 100%, respectively), patients with active tuberculosis and pulmonary vasculitis had severe to massive hemoptysis (50% and 44%, respectively). Transthoracic and other organ biopsies, spiral computed tomography (CT) angiography (X pres/GX model TSX-002a, Toshiba, Tochigi Ken, Japan) and aortography yielded high diagnostic results in our group (100%, 67%, 59% and 100%, respectively). The most frequent final diagnosis in patients with normal chest radiograph was pulmonary embolism (seven cases). CONCLUSIONS: Lung cancer, pulmonary embolism and bronchiectasis were the main causes of hemoptysis in this prospective cohort; however, this is the first report showing pulmonary embolism as a leading cause of hemoptysis. CT angiography with high-resolution CT should be the primary diagnostic modality if the initial investigation is inconclusive in hemoptysis cases.

[The evaluation of 92 interstitial lung disease patients]. / Klinigimizde interstisyel akciger hastaligi tanisi alan 92 hastanin incelenmesi.

Interstitial lung diseases (ILD) include many acute and chronic pulmonary disorders. We aimed to evaluate the patients diagnosed as ILD in our clinic. Between January 2000 and August 2004, 92 patients were included in the study. Fifty eight (63%) of our patients were female, 34 (37%) were male and the median age was 50.2 + or - 14.2 (19-80) years. The most frequent diagnoses were sarcoidosis in females, and IPF in males. The diagnostic methods used were as follows; clinically and radiologically in 36 (39.1%) patients, bronchoscopy in 33 (34.8%) patients, mediastinoscopy in 10 (10.9%) patients, open lung biopsy in 8 (8.7%) patients, skin biopsy in 2 (2.2%), oral mucosal biopsy in 1 (1.1%), lymph node biopsy in 1 (1.1%), renal biopsy in 1 (1.1%) and pleural fluid examination in 1 (1.1%). Bronchoscopic biopsies were diagnostic in 60.9% of sarcoid patients. Twelve (48%) IPF patients had an occupational toxic exposure history. Medical treatment were given to 80 patients. There were good clinical and radiological response in patients with sarcoidosis (96.9%) and cryptogenic organizing pneumonia (COP) (85.7%), however disease was stable in CTD patients and only three of idiopathic pulmonary fibrosis (IPF) patients (15.7%) responded to treatment. In IPF patients, diagnosis was established medially 35.7 months later after the first symptom appeared. Two of the IPF patients had also lung cancer. Treatment related complications occurred in six patients. Fourteen patients died during the follow-up period and eight were IPF. ILD is frequently encountered in general practice of pulmonary physicians and should be considered in differential diagnosis during routine pulmonology clinic. Sarcoidosis and IPF were the most commonly seen diseases. Although ILD is a difficult challenge to diagnose in clinical practice, it may be diagnosed by means of clinical features, radiologic techniques and several biopsy procedures.

Effects of two exercise interventions on pulmonary functions in the patients with ankylosing spondylitis.

OBJECTIVE: The aim of this study was to evaluate the impact of two different home-based daily exercise programs on pulmonary functions in the patients with ankylosing spondylitis (AS). METHODS: Fifty-one patients with AS were distributed into three groups. Group 1 (n=19) was given a conventional exercise regimen. Group 2 (n=19) received exercises based on the Global Posture Reeducation (GPR) method. Group 3 (n=13) was accepted as the control group. Patients were assessed according to pain, functional capacity (The Bath Ankylosing Spondylitis Functional Index - BASFI), disease activity (The Bath Ankylosing Spondylitis Disease Activity Index - BASDAI), chest expansion, pulmonary function parameters, and 6-min walk distance (6MWD) test. RESULTS: Although there were significant improvements for BASDAI and BASFI scores in all groups, significant improvements in the VAS pain, chest expansion, pulmonary function parameters and 6MWD test were observed in the exercise groups. The improvements in pain, functional capacity, disease activity, chest expansion, pulmonary function parameters and 6MWD test were better in the exercise groups than in the control group. The GPR method resulted in greater improvements than the conventional exercise program in specific pulmonary function parameters like forced vital capacity, forced expiratory volume in 1s, and peak expiratory flow parameters. CONCLUSION: Both exercises are efficient in improving pulmonary functions. Since the improvements in pulmonary function tests were greater in the patients who performed the exercise according to GPR method, motivated patients should be encouraged to perform this exercise program.

Role of bacteria in acute exacerbations of chronic obstructive pulmonary disease.

BACKGROUND AND STUDY OBJECTIVE: Infections are major causes of acute exacerbations of chronic obstructive pulmonary disease (COPD) which result in significant mortality and morbidity. The primary aim of the study was to determine the microbiological spectrum including atypical agents in acute exacerbations. The secondary aim was to evaluate resistance patterns in the microorganisms. METHODS: The sputum culture of 75 patients admitted to our clinic from January 1, 1999 to December 31, 2002 was evaluated prospectively, for aerobic Gram-positive and Gram-negative bacteria, and serologically for Chlamydophila pneumoniae and Mycoplasma pneumoniae. Sensitivity patterns in potentially pathogenic microorganisms (PPMs) were also investigated. RESULTS: An infectious agent was identified in 46 patients, either serologically or with sputum culture. Pathogens most commonly demonstrated were: Haemophilus influenzae (30%), Chlamydophila pneumoniae (17%), and Mycoplasma pneumoniae (9%). Mixed infections were diagnosed in 9 patients. PPMs showed a high resistance rate to commonly used antibiotics. CONCLUSION: We have shown that microorganisms causing acute exacerbations of COPD are not only typical bacteria (46%) but also atypical pathogens (26%), with unpredictable high rates. Typical agents showed a high resistance to commonly used antibiotics.

Massive pulmonary emboli and CT pulmonary angiography.

BACKGROUND: Massive pulmonary embolism (PE) is a devastating form of PE which usually results in acute right ventricular failure and death within 1-2 h. OBJECTIVES: To retrospectively assess pulmonary vascular, cardiac, pleural, and parenchymal findings on CT pulmonary angiography (CTPA) in patients with a diagnosis of massive PE (systolic blood pressure <90 mm Hg, syncope and/or shock). METHODS: In 33 consecutive patients with proven massive PE, hemodynamic severity was assessed by the extent of right ventricular dysfunction (RVD); diameter of the main pulmonary artery; the shape of the interventricular septum; and the extent of obstruction to the pulmonary arterial circulation (CT obstruction index). RESULTS: Central pulmonary arteries were embolized in all patients. RVD was detected in all patients (94% of them had severe RVD); the diameter of the main pulmonary artery was wider than normal in 76% of the patients; the shape of the interventricular septum was abnormal in all patients, and the CT obstruction index was higher than or equal to 50% in 85% of the patients. Wedge-shaped pleural-based consolidation was the most common parenchymal abnormality (36%). Pleural effusions were seen in 26 patients (79%). Twenty-eight patients were alive, and only the use of thrombolytic therapy was found to be statistically significant. CONCLUSIONS: In patients with acute massive PE, embolization of the central pulmonary arteries, RVD and displacement of the interventricular septum are commonly seen with CTPA. A CT obstruction index of >50% is commonly observed in massive PE. There was no association between CTPA findings and survival.

Comparison of vinorelbine-Cisplatin with gemcitabine-Cisplatin in patients with advanced non-small cell lung cancer.

PURPOSE: The objective of this trial was to compare cisplatin-plus-vinorelbine regimen with cisplatin-plus-gemcitabine regimen in patients with stage IIIB-IV non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Chemonaive patients with stage IIIB-IV NSCLC received either vinoelbine 30 mg/m(2) (days 1 and 8) plus cisplatin 80 mg/m(2) (day 1) every 21 days (VC arm) or gemcitabine 1250 mg/m(2) (days 1 and 8) plus cisplatin 80 mg/m(2) (day 1) every 21 days (GC arm). RESULTS: One hundred thirtyfour patients (67 VC and 67 GC) were included to the study. Overall response rates for the VC arm (31.2%) were not significantly different from that of the GC arm (34.3%). There were no differences in overall survival and one-year survival rates. Median survival and one-year survival rates for the VC and GC groups were 10.6 and 11.5 months, 45% and 46.8%, respectively. Grade 3-4 thrombocytopenia was significantly higher on the GC arm (VC 1.4% v GC 8.9%, p < 0.05), as was febrile neutropenia on the VC arm (VC 8.9% v GC 1.4%, p < 0.05). CONCLUSION: VC and GC demonstrated similar efficacy but there were differences in toxicity profiles.
