An in silico dosimetric evaluation of intensity-modulated radiation therapy (IMRT) vs 3-dimensional conventional radiation therapy (3D-CRT) treatment plans in postmastectomy radiation therapy (PMRT) to the chest wall and regional lymphatics was conducted. Twenty-five consecutive patients with breast cancer referred for locoregional PMRT, stages T2-4 with N1-3, were planned to receive 50 Gy in 25 fractions with IMRT. Additionally, a 3D-CRT plan was generated using identical contours for the clinical target volumes (CTV), planning target volumes (PTV), and organs at risk (OAR)...

OBJECTIVE: Adjuvant chemotherapy prolongs survival in patients with non-small cell lung cancer with N1 disease or tumors larger than 4 cm. Patients with T3N0 disease due to chest wall invasion often receive adjuvant chemotherapy because their disease is classified as stage II non-small cell lung cancer. This study evaluated whether chemotherapy improves survival after complete resection of T3N0 non-small cell lung cancer with invasion of the chest wall. METHODS: Patients who underwent complete resection of N0 non-small cell lung cancer with invasion of the chest wall were identified in the National Cancer Database...

The management of flail chest continues to evolve as scientific evidence and surgical experience accumulates. Flail chest injuries that span the sternum present a rare and complicated injury pattern that can be challenging to manage both medically and surgically. Our patient is a 69-year-old involved in a high-speed motor vehicle crash with respiratory failure secondary to an anterior flail chest. Tomographic examination confirmed a sternal fracture with bilateral sternochondral dislocations and multiple rib fractures...

BACKGROUND:  We compared the chest configurations of patients with primary spontaneous pneumothorax (PSP) and age-sex-matched controls to determine the presence of chest wall deformities in patients with PSP. METHODS:  We retrospectively enrolled 166 male patients with PSP (age, 18-19 years) and 85 age-sex-matched controls without PSP, who simultaneously underwent chest computed tomography (CT) and radiography at one of two institutes. After correcting for height, the following thoracic parameters were comparatively evaluated between the two groups: maximal internal transverse (T) and anteroposterior (W) diameters of the chest, maximal internal lung height (H), Haller index (T/W), and T/Height, T/H, W/Height, W/H, and H/Height ratios...

Coronary artery dissection and intramural hematoma after blunt chest trauma are rare, but life-threatening, complications. Coronary intramural hematoma extension is even rarer. A 31-year-old man was transferred to our hospital for worsening left chest pain during while he was admitted at a nearby hospital due to blunt chest trauma. Bedside echocardiography showed akinesis of the left ventricular apex and anterior wall as well as hypokinesis of the mid-to-basal anteroseptal wall and mid-to-basal lateral and posterior walls of the left ventricle...

REVIEW
Ross Mathiasen, Christopher Hogrefe
PURPOSE OF REVIEW: To provide a primary care perspective regarding the evaluation and management of shoulder pain and rotator cuff tears. RECENT FINDINGS: In the primary care setting, rotator cuff pathology is commonly encountered. Information regarding the risks of oral medications for the management of the associated pain keeps mounting. Partial-thickness rotator cuff tears remain difficult to diagnose with a single imaging modality. Musculoskeletal education in medical schools and non-orthopaedic residency and fellowship training programs continues to be an area for additional improvement...

OBJECTIVES: Persistent air leak or bronchopleural fistula (BPF) is a challenging and frequently observed problem after pulmonary resection and may lead to prolonged chest tube therapy. One efficient nonsurgical approach to manage such a fistula is the application of intrabronchial valves. This may support earlier chest tube removal and hospital discharge. METHODS: Between 04/2015 and 03/2017, n = 8 patients (n = 4 female) with severe pleural empyema and necrotising lung tissue defects developed prolonged air leak and persistent BPF after surgery...

PURPOSE: We observed that many of our helical therapy lung stereotactic body radiation therapy plans did not meet the Radiation Therapy Oncology Group (RTOG) recommended R50% (volume of 50% of the prescription dose/planning target volume), which characterizes the steepness of dose fall off. We hypothesized that despite not meeting R50%, helical therapy lung stereotactic body radiation therapy plans would confer similar local control and minimal side effects as previously reported using nonhelical treatment platforms...

BACKGROUND: Ascaris lumbricoides is one of the most common intestinal infections in developing countries, including Kosovo. In contrast to migration to the bile duct, migration of the worm to the gallbladder, due to the narrow and tortuous nature of the cystic duct, is rare. When it does occur, it incites acalculous cholecystitis. CASE PRESENTATIONS: This case series describes a 16-month-old Albanian girl, a 22-month-old Albanian girl, a 4-year-old Albanian girl, and a 10-year-old Albanian boy...

Perivascular epithelioid cell tumor (PEComa), mesenchymal tumors morphologically characterized by epithelioid cells, coexpress melanocytic and muscle markers. Herein, we describe a heretofore-undescribed tuberous sclerosis complex (TSC)-related neoplasm, morphologically resembling a soft tissue fibroma-like lesion, but showing an immunophenotype resembling PEComa. We identified 3 soft tissue fibroma-like lesions in individuals with TSC. We also evaluated 6 TSC-related periungual fibroma as well as a range of non-TSC fibroma-like lesions (n=19)...

RATIONALE: Esophageal manometry is the clinically available method to estimate pleural pressure, thus enabling calculation of the transpulmonary pressure (PL). However, many concerns make uncertain in which lung region esophageal manometry reflects local PL. OBJECTIVES: To determine the accuracy of esophageal pressure (Pes) and in which regions esophageal manometry reflects Ppl and PL; to assess whether lung stress in non-dependent regions can be estimated at end-inspiration from PL...

Bronchial thermoplasty (BT) is a bronchoscopic treatment for severe asthma using thermal energy to reduce smooth muscle in the bronchial wall. A 47-year-old man underwent BT for uncontrolled severe asthma despite maximal pharmacological treatment. After a third procedure, he experienced hypoxaemia because of complete bilateral upper lobe atelectasis. A pulmonary cyst suddenly emerged in to the right middle lobe, associated with the pneumothorax on postoperative day 6, and a chest drainage tube was inserted...

A 40-year-old man was transferred to our hospital following an isolated horse kick injury to the anterior chest wall. The case showed bi-fascicular block, severe tricuspid valve regurgitation due to ruptured chordae tendineae of the anterior leaflet, moderate mitral valve regurgitation due to prolapse of mitral anterior leaflet, and hypokinetic motion of the inferior septal wall. Both tricuspid and mitral insufficiency were completely repaired by a surgical operation. Fortunately, these injuries were not fatal in this case, but the comprehensive assessment of cardiac damage and careful observation are important for managing patients with cardiac injury...

BACKGROUND: Peripheral pulmonary lesions (PPLs) pose a diagnostic challenge, and the optimal investigation in many such cases remains unclear. Computed tomography (CT)-guided percutaneous needle biopsy (CT-PNB) has been the modality of choice for such lesions with a high diagnostic accuracy but with high rates of pneumothorax. Endobronchial ultrasound (EBUS) with a radial probe is an alternate diagnostic modality with increased diagnostic yield of bronchoscopy in the evaluation of PPL...
