Diagnostic efficacy of computed tomography-guided transthoracic needle aspiration and biopsy in patients with pulmonary disease

Background Computed tomography-guided transthoracic needle aspiration (TTNA) and biopsy (TTNB) is a well established, safe, and rapid method of reaching a definitive diagnosis for most thoracic lesions. The present study aimed to determine the roles of TTNA and TTNB in the diagnosis of pulmonary diseases and to compare the results using these two techniques. Methods TTNB and TTNA were performed in 105 patients admitted to our clinic due to peripheral pulmonary lesions between May 2005 and November 2007. Needle biopsies were performed using 18-gauge Tru-Cut® biopsy needles and aspirations was performed using 18-20-22-gauge Chiba needles. Results Malignant lesions diagnosed by TTNB were non-small cell lung carcinoma (51 patients, 73%), small cell lung carcinoma (nine patients, 13%), malignant tissue (three patients, 5%), lymphoma (two patients, 3%), thymoma (two patients, 3%), plasmacytoma (one patient, 1%), rhabdomyosarcoma (one patient, 1%), and metastasis (one patient, 1%). The malignant lesions diagnosed by TTNA were non-small cell lung carcinoma in eleven patients (92%) and malignant tissue in one patient (8%). Three (100%) of the benign lesions diagnosed by TTNB were granulomas and two (100%) benign lesions diagnosed by TTNA were infarctions. When the diagnostic value of TTNB and TTNA was compared, TTNB was significantly superior. Malignant lesions were identified in 70 (84%) and benign lesions were identified in three (4%) of the 83 patients in the TTNB group. Ten (12%) patients in the TTNB group could not be diagnosed. Malignant lesions were found in 12 (55%) and benign lesions were found in two (9%) of the 22 patients in the TTNA group. Negative results were obtained in eight (36%) patients. The diagnostic sensitivity, specificity, and accuracy of TTNB was calculated to be 92%, 100%, and 93%, respectively (Table 5). The diagnostic sensitivity, specificity, and accuracy of TTNA was 78%, 100%, and 82%, respectively. TTNB had a sensitivity of 92% (70/76) in malignant cases and 100% (3/3) in benign cases, while the sensitivity of TTNA in malignant and benign cases was 75% (3/4) and 67% (2/3), respectively. Conclusion TTNB is a safe and easy procedure which provides a highly accurate diagnosis of benign and malignant lung lesions without causing a significant increase in complication rates.

Thrombolytic treatment (alteplase; rt-Pa) in acute massive pulmonary embolism and cardiopulmonary arrest

Patients with pulmonary thromboembolism (PE) often decompensate suddenly, and once hemodynamic compromise has developed, mortality is extremely high. Currently, thrombolytic therapy for PE is still controversial. We retrospectively evaluated 34 patients with PE between January 2010 and December 2013 in the Department of Pulmonary Medicine, Medical Park Samsun Hospital, Samsun, Turkey. The demographic and disease characteristics of patients who received thrombolytic treatment were retrospectively analyzed. The female to male ratio was 19/15 and the mean age was 63.1±13.2 years. PE diagnosis was made using echocardiography (64.7%) or contrast-enhanced thorax computed tomography with echocardiography (32.4%). Twenty-two (64.7%) patients went into the cardiopulmonary arrest due to massive PE and 17 (50%) patients recovered without sequelae. Eleven (32.4%) patients were diagnosed with massive PE during cardiopulmonary arrest with clinical and echocardiographic findings. Alteplase (recombinant tissue plasminogen activator [rt-PA]) was administered during cardiopulmonary resuscitation (CPR) and four (36.3%) patients responded and survived without sequelae. The complications of rt-PA treatment were hemorrhage in five (14.7%) patients and allergic reactions in two (5.9%) patients. There was no mortality due to rt-PA treatment complications. In conclusion, mortality due to massive PE is much more than estimated and alteplase can be used safely in patients with massive PE. This thrombolytic treatment was not associated with any fatal hemorrhage complication. If there is any sign of acute PE, echocardiography should be used during cardiopulmonary arrest/instability. Alteplase should be given to patients with suspected massive PE.

The relationship between early reversibility test and maximal inspiratory pressure in patients with airway obstruction

Maximal inspiratory pressure (MIP) is a marker for assessing the degree of respiratory muscle dysfunction. Muscle dysfunction represents a pathophysiological feature of chronic obstructive pulmonary disease. We aimed to determinate the MIP value in patients with airway obstruction, to evaluate the change in MIP with bronchodilator drug, and to show the relationship between the changes in MIP and disease characteristics. We evaluated 21 patients with airway obstruction at the Department of Pulmonary Medicine, Samsun Medicalpark Hospital, Samsun, Turkey. We performed pulmonary function tests, measurement of MIP values, and reversibility tests with salbutamol. The baseline spirometry results were: mean forced vital capacity (FVC), 3,017±1,020 mL and 75.8%±20.8%; mean forced expiratory volume in 1 second (FEV1), 1,892±701 mL and 59.2%±18.2%; FEV1/FVC, 62.9%±5.5%; peak expiratory flow, 53%±19%. The pre-bronchodilator MIP value was 62.1±36.9 cmH2O. The reversibility test was found to be positive in 61.9% of patients with salbutamol. The absolute change and percentage of change in FEV1 were 318±223 mL and 19.8%±16.7%, respectively. The MIP value was increased by 5.5 cmH2O (8.8%) and was 67.7±30.3 cmH2O after bronchodilation. There was no significant relationship between age, FEV1, reversibility, and change in MIP with bronchodilator. However, the increase in MIP with bronchodilator drug was higher in patients with low body mass index (<25 kg/m2). We noted a 13.1% increase in FVC, a 19.8% increase in FEV1, a 20.2% increase in peak expiratory flow, and an 8.8% increase in MIP with salbutamol. In conclusion; MIP increases with bronchodilator therapy, regardless of changes in lung function, in patients with airway obstruction. The reversibilty test can be used to evaluate change in MIP with salbutamol.

A Very Rare Cause of Pleuritic Chest Pain: Bilateral Pleuritis as a First Sign of Familial Mediterranean Fever

The familial Mediterranean fever (FMF), also called recurrent polyserositis, is characterized by reccurrent episodes of serositis at pleura, peritoneum, and synovial membrane and fever. We present a patient with recurrent bilateral pleural effusion due to serositis attacks as a first sign of FMF. A 59-year-old Turkish man suffered from recurrent pleuritic chest pain due to pleural effusion and atelectasis. The etiology was not found, and his symptoms were spontaneously recovered during several weeks. The pleuritic chest pain was associated with abdominal pain in the last attack. The gene mutation analysis revealed the homozygosity of FMF (F479L) gene mutation in both our patient and his grandchild. After the colchicine treatment, the attack has not developed. In conclusion, recurrent pleural effusion and pleuritic chest pain may be the first signs of the FMF.

The objective evaluation of obstructive pulmonary diseases with spirometry

Airway obstruction is variable in asthma, while it is progressive and persistent in chronic bronchitis and emphysema. However, some of the patients presenting with symptoms of chronic airway diseases have clinical features of both asthma and COPD. The group with “Asthma–COPD Overlap Syndrome” (ACOS) phenotype was characterized by definitely irreversible airway obstruction accompanied by symptoms and signs of reversibility. In this study, we aimed to classify obstructive airway diseases by clinical, radiological, and pulmonary function tests. Patients at Samsun Medical Park Hospital Chest Diseases outpatient clinic were evaluated between January 2013 and April 2016, and a total of 235 patients were included in this study. Mean age of the patients was 55.3±14.5 (15–88) years, and the male/female ratio was 45/190. The baseline pulmonary function test results of the patients were as follows: mean forced vital capacity (FVC) values 2,825±1,108 (710–6,870) mL and 74.3±22.4 (24–155)%, forced expiratory volume in 1 second (FEV1) values 1,789±774 (480–4,810) mL and 58.1±20.0 (20–130)%, FEV1/FVC values 62.5±6.8 (39–70)%. Reversibility criteria following bronchodilator treatment were present in 107 (45.5%) patients. We specified five subgroups for patients according to their clinical, radiological, and pulmonary test findings, namely Group 1 (asthma), Group 2 (ACOS), Group 3 (chronic bronchitis), and Group 4 (emphysema). Additionally, a group of patients who had clinical and spirometric features of both asthma and chronic bronchitis in association with underlying emphysema (emphysema with chronic bronchitis and emphysema with asthma) was defined as the undifferentiated obstruction (UNDO) group. Number and percentage distribution of patients by groups were 58 (24.7%) in the asthma group, 70 (29.8%) in the ACOS group, 61 (26%) in the chronic bronchitis group, 32 (13.6%) in the emphysema group, and 14 (6%) in the UNDO group. In conclusion, in our study, the types of obstructive airway diseases could be classified based on clinical, radiological, and pulmonary function test findings into five groups, including asthma, ACOS, chronic bronchitis, emphysema, and both asthma and chronic bronchitis in association with underlying emphysema (emphysema with chronic bronchitis and emphysema with asthma) or the so-called undifferentiated obstruction. We suggest that these patient groups can be determined more accurately by studies that evaluate the association between spirometric FEV1, FEV1/FVC values, and reversibility ratios.

An Unusual Cause of Precordial Chest Pain

Extraskeletal chondrosarcoma in anterior mediastinum is very rare. A 45-year-old male patient was admitted to the hospital with precordial chest pain. A large and well-shaped mass in the anterior mediastinum was seen radiologically, and there was a clearly compression of the heart by the mass. The lesion was totally resected, and extraskeletal mediastinal chondrosarcoma was histopathologically diagnosed. We aimed to present and discuss the radiologic, clinic, and histopathologic features of unusual presentation of extraskeletal chondrosarcoma in a case.

A new syndrome: right-sided arcus aorta syndrome

Right-sided arcus aorta (RSAA) is a rare congenital anomaly that may cause chronic cough and dyspnoea. We aimed to define RSAA as a new syndrome characterised by RSAA, dyspnoea and cough during exercise. RSAA syndrome should be included in the differential diagnosis of asthma.

A case with iatrogenic pneumothorax due to deep dry needling

Deep dry needling is an evidence-based treatment technique that is accepted and used by physical therapists for treatment of musculoskeletal pain. We present a case of iatrogenic pneumothorax due to deep dry needling over the posterior thorax. A 36-year old presented with right chest pain 2 hours after dry needling for pain in his back muscles. Chest radiograph suggested small right pneumothorax and the finding was confirmed by computed tomography. Not only should practitioners and their patients be aware of potential complications of dry needling, but also physicians who might see patients with complications.

The cough frequency among call center workers: “call center cough”

Introduction Call centers are places where numerous people work together always speaking in a closed environment, and the most common complaint about admission to a doctor by call center employees is a cough and other respiratory system symptoms. Materials and Methods In this study, we aimed to demonstrate the relationship of call center employees between work and cough complaints and cough incidence with a questionnaire that consists of eleven questions and evaluates epidemiologic features, cough complaints of call center employees. Result 132 people were accrued to this study and the female/male ratio was 102/30. Mean age was 26.4 ± 2.7 (min-max; 21-39) years, mean working time at the call center was 2.6 ± 1.2 (min-max; 0.1-8) year and mean daily working hours was 8.1 ± 1.1 hour. 40 (30.3%) participants had cough complaint before beginning, 89 (67.4%) participants had cough complaint after to work at a call center work (p= 0.004). Conclusions Cough is more prevalent in call center employees. Pulmonary medicine specialist and occupational medicine practioner keep their mind unexplaned cough with infections or other reasons might be a warning and early symptoms of sick building syndrome or other building related diseases or voice abusing on call center operators.

Retrospective review of epidemic viral pneumonia cases in Turkey: A multicenter study

Influenza A (H1N1) caused its first pandemic in 2009 in USA and Mexico. Since then, clinicians have exercised great care in order to make an early diagnosis of viral pneumonias. This is due in part to pandemic influenza A infection having greater impact on populations <65 years old than other viral strains, including seasonal influenza. Chest radiographies of those affected displayed a rapid progression of patchy infiltrates, and a large proportion of individuals required admission to intensive care units (ICU). Despite efforts, patients infected with the virus had a high mortality rate. The present multicenter study aimed to retrospectively evaluate the clinical, demographic and prognostic characteristics of patients diagnosed with epidemic viral pneumonia in Turkey. A total of 92 patients were included in the study. The Students t-test and Chi-square tests were performed to analyze quantitative data, assuming a normal distribution, and to analyze qualitative data, respectively. Stepwise logistic regression was used to evaluate the effects of demographic variables and laboratory values on the virus mortality rate. The male/female ratio was 42/50 and the mean age was 48.74±16.65 years. A total of 69 (75%) patients were unvaccinated against influenza. The most common symptoms were cough (87%) and fever (63%). Chest computed tomography showed peripheral patchy areas of the lungs of ground glass density in 38 patients (41.3%). A total of 22 (59.4%) patients had H1N1, 5 (12.5%) patients had influenza B, and 38 (41.3%) patients met the criteria for admission to the ICU. Of these patients, 20 (52.63%) were monitored with a mechanical ventilator, with a noninvasive ventilator being adequate for 10 (26.32%) of patients. The length of stay in the ICU was 6.45±5.97 days and the duration of mechanical ventilation was 5.06±4.69 days. A total of 12 (13.04%) patients in the ICU succumbed. Logistic regression analysis revealed that among the parameters possibly associated with mortality, being an active smoker increased the risk of mortality 7.08-fold compared to other groups (P=0.005). In conclusion, viral pneumonia remains a significant health problem during the winter period. Considering the high number of ICU admissions and high rate of mortality for patients in the present study, earlier initiation of antiviral therapy is necessary. Active smoking increased mortality in viral pneumonia.
