RESUMO
Objective: While the coronavirus disease 2019 (COVID-19) pandemic was continuing at full speed, patients with Crimean-Congo hemorrhagic fever (CCHF), which is endemic in our region, apply to the emergency department simultaneously. The presence of computed tomography (CT) lesions suggesting COVID-19 in some CCHF patients has brought to our mind the question of whether there is CCHF lung involvement even though respiratory symptoms are not at the forefront. Methods: In this study, the findings of chest CT, demographic data and clinical symptoms of cases who had thorax tomography scan with suspicion of COVID-19 in the emergency department in the spring and summer of 2020 and were diagnosed with CCHF as a result of the evaluation and followed up in our clinic were compared with the findings of COVID-19 cases that were hospitalized and treated in the same period. Results: Seventy-seven COVID-19 and 25 CCHF cases were included in the study. Myalgia, headache, diarrhea, nausea and vomiting were significantly higher in CCHF patients ( p<0.05). Cough was significantly more common in COVID-19 patients ( p=0.034). Ground-glass opacity (GGO) was the most common tomography finding in CCHF, and cases without lung involvement were significantly higher (p=0.001). GGO, consolidation, vascularization, atelectasis band, reverse halo, air-bubble, nodule were significantly high in COVID-19 patients. Conclusion: During the epidemic period, no pathological finding was found in thoracic CT in most of the CCHF cases, and the presence of involvement in the lung tomography in cases with similar clinical and laboratory findings should primarily suggest the diagnosis of COVID-19.
RESUMO
INTRODUCTION: Pulmonary nodules are common incidental findings on computed tomography (CT). In Turkey, there is no available data about the follow-up of the frequency of incidental nodules. Our aim is to assess the frequency and size distrubition of incidental pulmonary nodule in our country. MATERIALS AND METHODS: Between January 2015 and December 2016, computed tomographies, taken of all outpatient and emergency department that recorded in the screening database were examined retrospectively. Nodules and their characteristics (number, size, density, localization) and relationship between age and gender were evaluated. RESULT: The age range of the cases was mean 58.99 ± 16.20 years, 256 (42.5%) were women and 347 (57.5%) were men. A total of 288 (48.25%) cases had 420 nodules. Solid nodule was present in 184 cases (30.5%). The number of cases with one solid nodule was 119 (64.7%). There were 124 solid nodules (55.36%) of ≥ 4-< 6 mm diameter, 64 solid nodules (28.57%) of ≥ 6-< 8 mm diameter and 36 solid nodules (16.07%) of ≥ 8 mm diameter. Nodule frequency increased statistically significantly with the age (p= 0.001). CONCLUSIONS: The frequency of incidental nodule was found higher than in our country than in developed countries.

BACKGROUND/AIM: The association between polymorphisms of xenobiotic/drug metabolizing enzymes and TP53 and response to chemotherapy and survival of patients with nonsmall cell lung cancer (NSCLC) are limited and inconclusive. In this study, CYP2E1*5B, CYP2E1*6, CYP2E1*7B, GSTO1 (A140D), and TP53 (Arg72Pro) polymorphisms and response to platinum-based chemotherapy and survival in 137 advanced stage NSCLC patients were investigated. MATERIALS AND METHODS: Genetic polymorphism analyses were determined by polymerase chain reaction (PCR) coupled with restriction fragment length polymorphism (RFLP). RESULTS: The patients with TP53 Pro/Pro variant were more likely to be resistant to chemotherapy than those with Arg/Arg variants with marginal significance (P = 0.066). We also analyzed these gene variants in combination with CYP1A1 (Ile462Val), CYP1B1 (Asn453Ser), GSTM1, GSTP1 exon 5 (Ile105Val), and GSTP1 exon 6 (Ala114Val) and GSTT1 polymorphic genes that we have previously genotyped in the same patients (Ada et al., Neoplasma, 57, 512-527, 2010). The multivariate analysis revealed that adjusted hazard ratio (HR) of death of the combined variant genotypes of TP53 (Arg72Pro, Pro72Pro) and CYP1A1 (Ile462Val, Val462Val) increased significantly as compared to wild-type genotypes (HR, 6.03; 95% CI, 1.39-26.04, P = 0.016). CONCLUSION: These results show that combined variant genotypes of TP53 (Arg72Pro, Pro72Pro) and CYP1A1 (Ile/Val, Val/Val) are associated with worsening of survival in NSCLC patients.

Non-small cell lung cancer (NSCLC) is the most common form of lung cancer. Genetic polymorphisms in tumour suppressor genes and genes encoding xenobiotic metabolising enzymes alter the activity of their corresponding enzymes and are important individual susceptibility factors for NSCLC. Because of the lack of information in literature, the aim of our study was to investigate the role of the tumour suppressor gene TP53 (Arg72Pro) and the xenobiotic metabolising CYP2E1*5B gene polymorphisms on the risk of NSCLC development. The study population consisted of 172 patients and 172 controls (156 men and 16 women in each group). Genetic polymorphisms were determined with real-time polymerase chain reaction (PCR) and PCR restriction fragment length polymorphism (PCR-RFLP). Multivariate analysis showed a significant association with NSCLC for the combination between the TP53 codon72 Arg/Pro and the Pro/Pro genotypes (OR 2.21, 95 % CI 1.390-3.51; p=0.001). We also analysed whether combinations of these gene variants with GSTM1, GSTT1, GSTP1 exon 5 (Ile105Val), and GSTP1 exon 6 (Ala114Val) gene polymorphisms were associated with the NSCLC risk. A significant increase in the risk was observed for the following combinations: TP53 codon72 variant with GSTM1 null (OR 2.22, 95 % CI 1.23-4.04; p=0.009), GSTT1 null (OR 2.98, 95 % CI 1.49-5.94; p=0.002), and GSTP1 (Ala114Val) variant genotypes (OR 3.38, 95 % CI 1.54-7.41; p=0.002). Further studies with larger samples are needed to verify these findings.

AIM: The early diagnosis and treatment of lung cancer are important for the prognosis of patients with lung cancer. This study was undertaken to investigate patient and doctor delays in the diagnosis and treatment of NSCLC and the factors affecting these delays. MATERIALS AND METHODS: A total of 1016 patients, including 926 (91.1%) males and 90 (8.9%) females with a mean age of 61.5±10.1 years, were enrolled prospectively in this study between May 2010 and May 2011 from 17 sites in various Turkish provinces. RESULTS: The patient delay was found to be 49.9±96.9 days, doctor delay was found to be 87.7±99.6 days, and total delay was found to be 131.3±135.2 days. The referral delay was found to be 61.6±127.2 days, diagnostic delay was found to be 20.4±44.5 days, and treatment delay was found to be 24.4±54.9 days. When the major factors responsible for these delays were examined, patient delay was found to be more frequent in workers, while referral delay was found to be more frequent in patients living in villages (p<0.05). We determined that referral delay, doctor delay, and total delay increased as the number of doctors who were consulted by patients increased (p<0.05). Additionally, we determined that diagnostic and treatment delays were more frequent at the early tumour stages in NSCLC patients (p<0.05). DISCUSSION: The extended length of patient delay underscores the necessity of educating people about lung cancer. To decrease doctor delay, education is a crucial first step. Additionally, to further reduce the diagnostic and treatment delays of chest specialists, multidisciplinary management and algorithms must be used regularly.

OBJECTIVE: Because pulmonary embolism (PE) and COPD exacerbation have similar presentations and symptoms, PE can be overlooked in COPD patients. Our objective was to determine the prevalence of PE during COPD exacerbation and to describe the clinical aspects in COPD patients diagnosed with PE. METHODS: This was a prospective study conducted at a university hospital in the city of Ankara, Turkey. We included all COPD patients who were hospitalized due to acute exacerbation of COPD between May of 2011 and May of 2013. All patients underwent clinical risk assessment, arterial blood gas analysis, chest CT angiography, and Doppler ultrasonography of the lower extremities. In addition, we measured D-dimer levels and N-terminal pro-brain natriuretic peptide (NT-pro-BNP) levels. RESULTS: We included 172 patients with COPD. The prevalence of PE was 29.1%. The patients with pleuritic chest pain, lower limb asymmetry, and high NT-pro-BNP levels were more likely to develop PE, as were those who were obese or immobile. Obesity and lower limb asymmetry were independent predictors of PE during COPD exacerbation (OR = 4.97; 95% CI, 1.775-13.931 and OR = 2.329; 95% CI, 1.127-7.105, respectively). CONCLUSIONS: The prevalence of PE in patients with COPD exacerbation was higher than expected. The association between PE and COPD exacerbation should be considered, especially in patients who are immobile or obese.

OBJETIVO: Visto que a embolia pulmonar (EP) e a exacerbação da DPOC têm apresentação e sintomas comuns, o diagnóstico de EP pode ser negligenciado nesses pacientes. Nosso objetivo foi determinar a prevalência de EP durante a exacerbação da DPOC e descrever os aspectos clínicos em portadores de DPOC diagnosticados com EP. MÉTODOS: Estudo prospectivo conduzido em um hospital universitário na cidade de Ancara, Turquia. Entre maio de 2011 e maio de 2013, todos os pacientes hospitalizados por exacerbação aguda da DPOC foram incluídos no estudo. Todos os pacientes foram submetidos a avaliação de risco clínico, gasometria arterial, angiotomografia de tórax e ultrassonografia Doppler de membros inferiores. Além disso, foram medidos os níveis de dímero-D e de N-terminal pro-brain natriuretic peptide (NT-pro-BNP). RESULTADOS: Foram incluídos 172 pacientes com DPOC. A prevalência de EP foi de 29,1 %. Os pacientes com DPOC e dor torácica pleurítica, assimetria de membros inferiores e altos níveis de NT-pro-BNP, assim como aqueles que estavam obesos ou imobilizados, apresentavam maior probabilidade de desenvolver EP. Obesidade e assimetria de membros inferiores foram preditores independentes de EP nos pacientes com exacerbação da DPOC (OR = 4,97; IC95%, 1,775-13,931 e OR = 2,329; IC95% CI, 1,127-7,105, respectivamente). CONCLUSÕES: A prevalência de EP em pacientes com exacerbação da DPOC foi maior que a esperada. A associação entre EP e exacerbação da DPOC deve ser considerada nesses pacientes, especialmente naqueles imobilizados ou obesos. .

OBJECTIVE: The aim of this study was to evaluate the D-dimer levels in patients with chronic obstructive pulmonary disease (COPD) exacerbation with and without pulmonary embolism (PE) and to attempt to define a new cut-off value for D-dimer to exclude the diagnosis of PE in patients with COPD exacerbation. METHODS: This cross-sectional study was performed between the June 2012 and January 2013. The COPD patients who were admitted to the emergency department with acute exacerbation were consecutively included. D-dimer levels were measured upon admission. All patients underwent computed tomography angiography (CTA) and Doppler ultrasonography (US) of the lower extremities. RESULTS: A total of 148 patients were enrolled. Fifty-three patients (36%) who did not have PE had higher than normal (>0.5 pg/mL) D-dimer levels. The D-dimer levels of the COPD patients with PE were significantly higher than those of the patients without PE (2.38±2.80 vs. 1.06±1.51 pg/mL) (P<0.001). The cut-off value for D-dimer in diagnosing PE in the COPD patients was 0.95 pg/mL. The area under the receiver operating characteristic (ROC) curve was 0.752±0.040 (95% CI: 0.672-0.831) (P<0.001). CONCLUSIONS: This study showed that the D-dimer concentrations of COPD patients who are in the exacerbation period may be higher than normal, even without PE. The cut-off level for D-dimer was 0.95 pg/mL (sensitivity 70%, spesificity 71%) for the exclusion of PE in the patients with COPD exacerbation. The D-dimer cut-off value that is used to exclude PE in patients with acute exacerbation of COPD should be reevaluated to prevent the excessive use of further diagnostic procedures.
RESUMO
OBJECTIVE: Pulmonary embolism (PE) is an important complication of major orthopedic surgery. The aim of this study was to evaluate the incidence of venous thromboembolism (VTE) and factors influencing the development of VTE in patients undergoing major orthopedic surgery in a university hospital. METHODS: Patients who underwent major orthopedic surgery (hip arthroplasty, knee arthroplasty, or femur fracture repair) between February of 2006 and June of 2012 were retrospectively included in the study. The incidences of PE and deep vein thrombosis (DVT) were evaluated, as were the factors influencing their development, such as type of operation, age, and comorbidities. RESULTS: We reviewed the medical records of 1,306 patients. The proportions of knee arthroplasty, hip arthroplasty, and femur fracture repair were 63.4%, 29.9%, and 6.7%, respectively. The cumulative incidence of PE and DVT in patients undergoing major orthopedic surgery was 1.99% and 2.22%, respectively. Most of the patients presented with PE and DVT (61.5% and 72.4%, respectively) within the first 72 h after surgery. Patients undergoing femur fracture repair, those aged ≥ 65 years, and bedridden patients were at a higher risk for developing VTE. CONCLUSIONS: Our results show that VTE was a significant complication of major orthopedic surgery, despite the use of thromboprophylaxis. Clinicians should be aware of VTE, especially during the perioperative period and in bedridden, elderly patients (≥ 65 years of age).

Recent years have seen a growing evidence of ethnic differences in the frequency of glutathione S-transferase omega 1 (GSTO1) A140D gene polymorphism, which is associated with various cancers such as breast and liver. Until now however, no association has been investigated between the GSTO1 A140D polymorphism and lung cancer. The aim of our study was to see if there was one in the Turkish population. To do that, we identified GSTO1 A140D polymorphism in 214 unrelated healthy individuals and 172 patients with non-small cell lung cancer (NSCLC) using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The frequencies of A/A (wild type), A/D (heterozygous mutant), and D/D (homozygous mutant) GSTO1 A140D genotypes in healthy subjects were 48%, 41%, and 11%, respectively. In NSCLC patients they were 48%, 45%, and 7%, respectively. We found no significant association between the GSTO1 A140D gene polymorphism and NSCLC or its histological subtypes, namely squamous cell carcinoma or adenocarcinoma. Furthermore, this polymorphism did not correlate with smoking. Our study is the first to show that the frequency of GSTO1 A140D gene polymorphism in the Turkish population is similar to other Caucasian populations and that this polymorphism is not associated with susceptibility to NSCLC.

OBJETIVO: A embolia pulmonar (EP) é uma complicação importante de cirurgia ortopédica de grande porte. Este estudo visou avaliar a incidência de tromboembolismo venoso (TEV) e os fatores que influenciam o desenvolvimento de TEV em pacientes submetidos a cirurgia ortopédica de grande porte em um hospital universitário. MÉTODOS: Pacientes submetidos a cirurgia ortopédica de grande porte (artroplastia de quadril, artroplastia do joelho ou reparação de fratura de fêmur) entre fevereiro de 2006 e junho de 2012 foram incluídos retrospectivamente no estudo. As incidências de EP e de trombose venosa profunda (TVP) foram avaliadas, assim como os fatores que influenciaram sua ocorrência, tais como o tipo de cirurgia, idade e comorbidades. RESULTADOS: Foram revisados os prontuários médicos de 1.306 pacientes. As proporções de artroplastia do joelho, artroplastia de quadril e reparação de fratura de fêmur foram, respectivamente, de 63,4%, 29,9% e 6,7%. A incidência cumulativa de EP e TVP nos pacientes submetidos a cirurgia ortopédica de grande porte foi, respectivamente, de 1,99% e 2,22%. A maioria dos pacientes apresentou EP e TVP (61,5% e 72,4 %, respectivamente) nas primeiras 72 h após a cirurgia. Pacientes submetidos à reparação de fratura de fêmur, aqueles com idade ≥ 65 anos, e pacientes acamados tinham um risco maior de desenvolver TVP. CONCLUSÕES: Nossos resultados demonstram que o TEV foi uma complicação importante de cirurgia ortopédica de grande porte, apesar da utilização de tromboprofilaxia. Os médicos clínicos devem estar alerta para a ocorrência ...

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) has extrapulmonary effects that seems to be related with systemic inflammation. The relationship between metabolic syndrome which is an important determinant of systemic inflammation in general population and COPD is still not clear. The aim of the current study was to investigate the frequency of metabolic syndrome and C-reactive protein (CRP) levels, as a marker of systemic inflammation in stable COPD patients with different severity levels and in age and sex matched control group. PATIENTS AND METHODS: Ninety-one stable COPD patients and 42 control subjects were included in the study. The severity level in patients with COPD were determined according to GOLD (Global Initiative for Chronic Obstructive Lung Disease) criteria. ATP III (The National Cholesterol Education Program's Adult Treatment Panel III) was used in diagnosis of metabolic syndrome. Hs-CRP levels were measured in venous samples of patients and control subjects. RESULTS: The frequency of metabolic syndrome was found higher in patient group than control subjects, especially in GOLD stages I, II (p= 0.004). Abdominal obesity, hypertension, hyperglycemia components of metabolic syndrome were significantly more prevalent in patient group (p< 0.0001). Increased CRP levels were higher in control and patient groups in all GOLD stages, with metabolic syndrome than without metabolic syndrome (p= 0.047, p= 0.217, p< 0.001, p= 0.05, p= 0.467). CONCLUSION: The study showed that frequency of metabolic syndrome was higher in stable COPD patients than control subjects and general Turkish population. Abdominal obesity, hypertension and hyperglycemia were significantly more prevalent in patient group. Systemic inflammation was more intense in COPD patients with metabolic syndrome than without metabolic syndrome.

Several studies focused on investigating genetic polymorphisms in order to estimate genetic contribution to lung cancer often showed conflicting results. In this study, we investigated the role of GSTM1, GSTT1, GSTP1 exon 5 and exon 6 polymorphisms on developing lung cancer and histological subtypes in 213 lung cancer patients and 231 controls. GSTM1 null, GSTT1 null, and GSTP1 exon 5 variant genotypes did not show a significant risk for developing lung cancer overall. Significant association was noted between GSTP1 exon 6 variant genotypes and overall lung cancer risk (OR 2.17, 95% CI 1.25-3.78; P = 0.006). These results show that GSTP1 exon 6 polymorphism might be an important factor in determining lung cancer susceptibility in a Turkish population.

There are many studies supporting the family history in lung cancer. The study included 213 subjects with new and former diagnoses of lung cancer. Patients were enrolled from the Department of Chest Diseases Ankara University Faculty of Medicine and Atatürk Chest Diseases and Chest Surgery Training and Research Hospital between January-June 2005. For the control group, 200 healthy subjects were gathered. We aimed to investigate the family predisposition for lung and other cancers, additionally the relationship of this predisposition to age, gender, smoking habits and cell types. The number of first degree relatives of patients and control group were 2058 and 2045, respectively. In conclusion, positive family history for cancer estimated in 38% of 213 individuals with lung cancer. In these individuals, 41.9% had lung cancer, 19% had gastrointestinal system cancer, 7.6% had breast cancer, 5.7% had prostate cancer, 25.7% had other system cancers (larinx, skin, bone, hematologic system, central nervous system). Besides, 4.6% of 213 patients had accompanying other system cancers (urinary bladder, kidney, lung, head-neck). In control group, positive family history for the cancer was 21.5% and this was statistically significant (p< 0.001). In the family members of patients with lung cancer, the risks of lung, gastrointestinal system and breast cancer development were increased. Besides, the lung and other system cancers (except prostate and gastrointestinal system cancers) were significantly increased at the brothers of patients with lung cancer, supporting the genetical transition hypothesis. The presence of head-neck, bladder, prostate, lung and kidney cancers in the history of the patients increase the risk of lung cancer, supporting the genetic transition.

Hemoptysis is an important respiratory symptom that may be fatal. Despite of the advanced diagnostic procedures, etiology of hemoptysis in some patients remains unclear. The partial pulmonary artery agenesis and systemic shunt was detected by us, in a 25 year-old female patient which has been hemoptysis with unknown etiology for 5 years. Symptoms of the patient was taken under control by embolisation procedure. The aim of this report is to take attention to this rare cause of hemoptysis and to emphasize that pulmonary angiography should be considered in the diagnosis of the hemoptysis with unknown etiology.

Assessment of asthma with a control test is suggested as a relevant approach for recent years. Ideally, an asthma control test should apply not only to clinical manifestations but also to laboratory markers of inflammation as well. Until now, this could not be performed because of the lack of a confirmed marker which indicates inflammation. A fibrotic mediator TGF-beta 1 has been reported as a key mediator of remodeling in asthma. The aim of this study is to evaluate plasma TGF-beta 1 level in stable asthmatic sufferers and to investigate its correlation with the asthma control test. Stable asthmatic sufferers and healthy controls were recruited for this study. After obtaining demographic information, skin prick and asthma control tests were performed. Blood samples were collected for plasma TGF-beta 1 level. Any contributing factors that may affect plasma TGF-beta 1 level were excluded from both groups. Thirty-five atopic, 35 nonatopic asthmatic sufferers and 15 healthy control subjects were included for this study. The mean age was 38 +/- 10 (years) and 61% were female. When the asthmatic group compared with the control group, plasma TGF-beta 1 level was significantly higher in the asthmatic group (41.7 +/- 12.6 ng/mL versus 27.6 +/- 13 ng/mL) (p < 0.05) whereas it was similar among the atopic and nonatopic groups (41.8 +/- 14.2 ng/mL versus 41.6 +/- 11 ng/mL) (p > 0.05). Spearman Correlation Analysis results pointed positive correlation between uncontrolled asthma and plasma TGF-beta 1 level. This study shows that plasma TGF-beta 1 level may be a systemic marker of asthma control.

BACKGROUND: A number of studies have implicated an association between H. pylori and diverse extra-gastroduodenal pathologies. Chronic inflammation and increased immune response have been observed in bronchiectasis, likely gastroduodenal inflammatory diseases. H. pylori has been found in the trachea-bronchial aspirates of mechanically ventilated patients. Furthermore, the seroprevalence of H. pylori was found to be significantly higher in patients with bronchiectasis than in the control group. The present study was performed to investigate the possible role of H. pylori in the pathogenesis of bronchiectasis. METHODS: Prospectively, bronchoalveolar lavage fluid (BALF) was obtained from patients with bronchiectasis (n=26) and control (n=20). BALF was subjected to polymerase chain reaction (PCR) to determine the presence of H. pylori and serum IgG against H. pylori was determined with micro-ELISA kit. In addition, PCR was performed to determine H. pylori in surgically removed lung tissues from patients with bronchiectasis (n=97). RESULTS: H. pylori DNA was not detected in the BALF or in lung tissue samples. In addition, anti-H. pylori IgG level in patients with bronchiectasis did not show statistically significant difference from that of the control. CONCLUSIONS: Our study provided evidence that there might be no direct association between H. pylori and bronchiectasis; however, the indirect role of soluble products of H. pylori could not be excluded.

To determine the bacterial etiology of lower respiratory tract infections (LRTIs) in Turkey, quantitative cultures of sputum were carried out. The major pathogens for LTRIs were found to be Haemophilus influenzae, followed by Streptococcus pneumoniae and Moraxella catarrhalis. Only 6.1% of the H. inlfuenzae and all strains of M. catarrhalis were beta-lactamase producers. An E-test showed that 31.2% of the S. pneumoniae strains had an intermediate resistance to penicillin, and the remaining strains were susceptible; no fully resistant strains were detected.
