Frequencies of EGFR single nucleotide polymorphisms in non-small cell lung cancer patients and healthy individuals in the Republic of Serbia: a preliminary study.

The purpose of this study was to determine the frequencies of EGFR -216G>T, -191C>A, and 181946C>T in Serbian non-small cell lung cancer (NSCLC) patients, as well as to compare it with healthy individuals, in order to assess their potential importance for lung cancer in Serbia. The study involved 56 NSCLC patients and 53 unrelated healthy volunteers, and genotyping was performed on DNA samples obtained from formalin-fixed paraffin-embedded lung tumor tissue and blood, respectively. This was the first time to show genotype frequencies of those single nucleotide polymorphisms for this study group from the territory of the Republic of Serbia.

Radial Endobronchial Ultrasound (EBUS) Guided Suction Catheter-Biopsy in Histological Diagnosis of Peripheral Pulmonary Lesions.

Background: EBUS guided trans-bronchial biopsy became routine in diagnosis of peripheral pulmonary lesions (PPL). Suction catheter-biopsy is a technique for obtaining a tissue sample from peripheral lung parenchyma. Aim of this study was to evaluate diagnostic efficiency, feasibility and safety of EBUS guided suction catheter-biopsy (SCB) in comparison to trans-bronchial biopsy (TBB) in diagnosis of PPL.

Confidence level in venipuncture and knowledge on causes of in vitro hemolysis among healthcare professionals.

Introduction: This study aimed to assess confidence level of healthcare professionals in venipuncture and their knowledge on the possible causes of in vitro hemolysis.

Materials And Methods: A sample of 94 healthcare professionals (nurses and laboratory technicians) participated in this survey study. A four-section questionnaire was used as a research instrument comprising general information for research participants, knowledge on possible causes of in vitro hemolysis due to type of material used and venipuncture technique and specimen handling, as well as assessment of healthcare professionals' confidence level in their own ability to perform first and last venipuncture.

EGFR-TKIs in adjuvant treatment of lung cancer: to give or not to give?

Epidermal growth factor receptor-tyrosine-kinase inhibitors (EGFR-TKIs) brought a significant revolution in the treatment of non-small-cell lung cancer (NSCLC). In a short period of time, EGFR-TKIs became the standard of treatment for mutation-positive, advanced stage non-squamous NSCLC. In recent years, second- and third-generation EGFR-TKIs are emerging, further widening the clinical use.

Electric vs. harmonic scalpel in treatment of primary focal hyperhidrosis with thoracoscopic sympathectomy.

Background: Hyperhidrosis is defined as excessive sweating beyond the physiologic needs of a person. Palmar hyperhidrosis in the adolescent period may have an impact on school work and may cause psychological problems. Thoracoscopic sympathectomy is now used routinely to treat patients with disabling primary hyperhidrosis or facial blushing.

Lung abscess-etiology, diagnostic and treatment options.

Lung abscess is a type of liquefactive necrosis of the lung tissue and formation of cavities (more than 2 cm) containing necrotic debris or fluid caused by microbial infection. It can be caused by aspiration, which may occur during altered consciousness and it usually causes a pus-filled cavity. Moreover, alcoholism is the most common condition predisposing to lung abscesses.

Induction chemoradiation in stage IIIA/N2 non-small-cell lung cancer: a phase 3 randomised trial.

Background: One of the standard options in the treatment of stage IIIA/N2 non-small-cell lung cancer is neoadjuvant chemotherapy and surgery. We did a randomised trial to investigate whether the addition of neoadjuvant radiotherapy improves outcomes.

Methods: We enrolled patients in 23 centres in Switzerland, Germany and Serbia.

Pulmonary arteriovenous malformation-etiology, clinical four case presentations and review of the literature.

Pulmonary arteriovenous malformation (PAVM) is a rare clinical condition with abnormal direct communication between the branches of pulmonary artery and vein. It may occur as an isolated anomaly or in association with hereditary hemorrhagic telangiectasia (HHT). Although these vascular pulmonary pathologies are quite uncommon, they are the important part of the differential diagnosis of common pulmonary problems such as hypoxemia and pulmonary nodules.

A randomized phase II study of ganetespib, a heat shock protein 90 inhibitor, in combination with docetaxel in second-line therapy of advanced non-small cell lung cancer (GALAXY-1).

Background: This trial was designed to evaluate the activity and safety of ganetespib in combination with docetaxel in advanced non-small cell lung cancer (NSCLC) and to identify patient populations most likely to benefit from the combination.

Patients And Methods: Patients with one prior systemic therapy for advanced disease were eligible. Docetaxel (75 mg/m(2) on day 1) was administered alone or with ganetespib (150 mg/m(2) on days 1 and 15) every 3 weeks.

Pneumothorax as a complication of central venous catheter insertion.

The central venous catheter (CVC) is a catheter placed into a large vein in the neck [internal jugular vein (IJV)], chest (subclavian vein or axillary vein) or groin (femoral vein). There are several situations that require the insertion of a CVC mainly to administer medications or fluids, obtain blood tests (specifically the "central venous oxygen saturation"), and measure central venous pressure. CVC usually remain in place for a longer period of time than other venous access devices.

Semi-Fowler vs. lateral decubitus position for thoracoscopic sympathectomy in treatment of primary focal hyperhidrosis.

Background And Objective: The aim of this study is to compare usefulness of Semi-Fowler position vs. lateral decubitus position for thoracoscopic sympathectomy in treatment of primary focal hyperhidrosis.

Materials And Methods: From January 2009 to January 2010, 263 consecutive patients with palmar and axillar hyperhidrosis underwent thoracoscopic sympathectomy Th2-Th4.

Checklist for early recognition and treatment of acute illness: International collaboration to improve critical care practice.

Processes to ensure world-wide best-practice for critical care delivery are likely to minimize preventable death, disability and costly complications for any healthcare system's sickest patients, but no large-scale efforts have so far been undertaken towards these goals. The advances in medical informatics and human factors engineering have provided possibility for novel and user-friendly clinical decision support tools that can be applied in a complex and busy hospital setting. To facilitate timely and accurate best-practice delivery in critically ill patients international group of intensive care unit (ICU) physicians and researchers developed a simple decision support tool: Checklist for Early Recognition and Treatment of Acute Illness (CERTAIN).

A survey on critical care resources and practices in low- and middle-income countries.

Background: Timely and appropriate care is the key to achieving good outcomes in acutely ill patients, but the effectiveness of critical care may be limited in resource-limited settings.

Objectives: This study sought to understand how to implement best practices in intensive care units (ICU) in low- and middle-income countries (LMIC) and to develop a point-of-care training and decision-support tool.

Methods: An internationally representative group of clinicians performed a 22-item capacity-and-needs assessment survey in a convenience sample of 13 ICU in Eastern Europe (4), Asia (4), Latin America (3), and Africa (2), between April and July 2012.

Neodymium yttrium-aluminium-garnet laser resection significantly improves quality of life in patients with malignant central airway obstruction due to lung cancer.

Neodymium yttrium-aluminium-garnet (Nd : YAG) laser resection is one of the mostly used interventional pulmonology techniques for urgent desobstruction of malignant central airway obstruction (CAO). The major aim of this trial was to evaluate potential influence of Nd : YAG laser resection on overall quality of life (QoL) in patients with central lung cancer. Patients with malignant CAO scheduled for Nd : YAG laser resection were prospectively recruited in the trial.

Pneumothorax in cystic fibrosis.

Pneumothorax is recognized as a common and life-threatening complication in cystic fibrosis (CF) patients, especially in those who are infected with P. aeruginosa, B. cepacia or Aspergillus, need enteral feeding, are diagnosed as suffering from allergic bronchopulmonary aspergillosis (ABPA), developed massive hemoptysis, and their respiratory function is seriously compromised.

Tube thoracostomy; chest tube implantation and follow up.

Pneumothorax is an urgent medical situation that requires urgent treatment. We can divide this entity based on the etiology to primary and secondary. Chest tube implantation can be performed either in the upper chest wall or lower.

Pneumothorax in sarcoidosis.

While sarcoidosis is a relatively common but often underdiagnosed disease, pneumothorax appears to be a rare clinical event observed mostly at the late stages of the disease course. The precise underlying mechanism of such complication is unclear and probably involves the formation of bullae due to bronchial obstruction and retraction-collapse of distracted lung tissue. Thoracoscopic bullectomy represent the preferred treatment option for recurrent pneumothoraces.

Penetrating trauma.

Pneumothorax occurs when air enters the pleural space. Currently there is increasing incidence of road traffic accidents, increasing awareness of healthcare leading to more advanced diagnostic procedures, and increasing number of admissions in intensive care units are responsible for traumatic (non iatrogenic and iatrogenic) pneumothorax. Pneumothorax has a clinical spectrum from asymptomatic patient to life-threatening situations.

Catamenial pneumothorax.

Catamenial pneumothorax (CP) is the most common form of thoracic endometriosis syndrome, which also includes catamenial hemothorax, catamenial hemoptysis, catamenial hemopneumothorax and endometriosis lung nodules, as well as some exceptional presentations. Usually onset of lung collapse is less than 72 hours after menstruation. Most commonly occurs in women aged 30-40 years, but has been diagnosed in young girls as early as 10 years of age and post menopausal women (exclusively in women of menstrual age) most with a history of pelvic endometriosis.

Acute respiratory distress syndrome and pneumothorax.

Acute respiratory distress syndrome (ARDS) can occur during the treatment of several diseases and in several interventional procedures as a complication. It is a difficult situation to handle and special care should be applied to the patients. Mechanical ventilation is used for these patients and several parameters are changed constantly until compliance is achieved.

Pneumothorax: observation.

Pneumothorax based on the cause, it can be divided into two large categories; primary and secondary. The staging of pneumothorax plays a crucial role for treatment. Currently both thoracic surgeons and pulmonary physicians can handle efficiently treatment.

Pneumothorax: from definition to diagnosis and treatment.

Pneumothorax is an urgent situation that has to be treated immediately upon diagnosis. Pneumothorax is divided to primary and secondary. A primary pneumothorax is considered the one that occurs without an apparent cause and in the absence of significant lung disease.

Paraneoplastic dermatomyositis associated with adenocarcinoma of the lung.

The association of dermatomyositis and lung cancer has been recognized a long time ago. The case of a 57-year old patient with lung adenocarcinoma and dermatomyositis as the first sign of the illness is presented. The occurrence of dermatomyositis should be considered as a potential presentation of paraneoplastic syndromes, particularly in patients at risk for lung cancer.
