#1
Seung-Hee Loh, Bark-Lynn Lew, Woo-Young Sim
Phacomatosis pigmentokeratotica is a recently identified disease characterized by the coexistence of an epidermal nevus with sebaceous differentiation arranged along Blaschko lines and a speckled lentiginous nevus showing a checkerboard pattern, mostly in association with various extracutaneous defects. A 52-year-old man presented with asymptomatic ulcerative plaque on his left side of perioral area. A 2 × 2-cm-sized fleshy colored ulceration on his left perioral area was consistent with basal cell carcinoma with nevus sebaceous...

Blunt injuries to the chest wall are an important chapter on emergency room (ER) departments, being the third most common injuries in trauma patients which ominous complications could appear. This article describes different types of traumatic events affecting the chest wall, which maybe misdiagnosed with conventional X-ray. Special emphasis has been done in computed tomography (CT) and multidetector CT (MDCT) imaging. This technique is considered the "gold-standard" for those traumatic patients, due to its fast acquisition covering the whole area of interest in axial plane, reconstructing multiplanar (2D, 3D) volume-rendered images with a superb quality and angiographic CT capabilities for evaluating vascular damage...

Ataxia telangiectasia mutated (ATM) gene mutations may confer increased sensitivity to ionizing radiation and increased risk of late toxicity for cancer patients. We present the case of a 55-year-old female treated with adjuvant breast and regional nodal radiation following lumpectomy and axillary lymph node dissection for stage II invasive ductal carcinoma of the breast. She developed severe telangiectasia, fibrosis, induration, chest wall pain (with evidence of rib fractures on imaging), and painful limitation in her range of motion at the shoulder...

Stand-alone cone beam computed tomography (CT) and single-photon emission computed tomography (SPECT) systems capable of complex acquisition trajectories have previously been developed for breast imaging. Fully three-dimensional (3-D) motions of SPECT systems provide views into the chest wall and throughout the entire volume. The polar tilting capability of the CBCT system has shown improvement in sampling close to the chest wall, while eliminating cone beam artifacts. Here, a single hybrid SPECT-CT system, with each individual modality capable of independently traversing complex trajectories around a common pendant breast volume, was developed...

An 80-year-old man presented with a right side lung tumor. The tumor was not abutting the bronchus or chest wall; thus, endobronchial ultrasound (EBUS) and CT-guided biopsy were considered to be technically difficult. We therefore attempted endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). Although the nodule was not abutting the esophagus on CT, an irregularly shaped hypoechoic lesion was visualized on EUS. EUS-FNA was successfully performed. The tumor was diagnosed as squamous cell carcinoma...

A term male baby, after delivery, was found to have a 3-centimeter beefy-red mass protruding from the left chest wall, adjacent to the left nipple. Radiological imaging suggested it's origin from the left lateral liver segment. A diagnostic laparoscopy confirmed the isolated connection to the liver, elevated left hemidiaphragm, and protrusion between the ribs. The mass was excised using electrocautery, and pathologic examination showed normal liver tissue.

AIMS: Poor data exist about cardiac magnetic resonance (CMR) findings in a large sample of acute myocarditis with different clinical presentations (heart failure, arrhythmias, and infarct-like presentation). METHODS: Five hundred and forty-three in-patients with a clinical suspected of acute myocarditis confirmed by CMR were enrolled. The clinical indications to perform CMR were chest pain and/or dyspnea and/or palpitations, or effort intolerance/malaise in the last month; elevated troponin and/or new ventricular dysfunction, and/or new ECG abnormalities; and suspected inflammatory cause...

Patient with Pancoast Tumor usually present in advanced stage of the disease which requires chemotherapy and radiotherapy as options of treatment. Histologic confirmation is a key for further treatment of these patients. Normally in bronchoscopy the lesion can't be visualised and in result making biopsy difficult to perform. Transthoracic biopsy through computed tomography poses anatomic difficulties and not always the pulmonary lesion can be reached. We report a case of pancoast tumor in a 68 year old male who presented with left arm pain and upper lobe increased density mass in chest x ray...

Both noncontrast and contrast-enhanced approaches to gated thoracic magnetic resonance angiography (MRA) for aortic root evaluation have been reported at 3T. We compare qualitative and quantitative image quality measures for the two approaches, and assess the reproducibility of standard aortic measurements. Respiratory and cardiac gated MRA of the chest was performed at 3T in 45 patients: 23 after administration of iron-based blood pool contrast, and 22 without contrast. Image quality was assessed with a 5-point Likert scale, vessel lumen-to-muscle contrast ratios, and vessel wall sharpness...

Ventilator-induced lung injury (VILI) results from mechanical disruption of blood-gas barrier and consequent edema and releases of inflammatory mediators. A transpulmonary pressure (PL) of 17 cmH2O increases baby lung volume to its anatomical limit, predisposing to VILI. Viscoelastic property of lung makes pulmonary mechanics time dependent so that stress (PL) increases with respiratory rate. Alveolar inhomogeneity in acute respiratory distress syndrome acts as a stress riser, multiplying global stress at regional level experienced by baby lung...

BACKGROUND: Obesity is a common co-morbidity of COPD and has been associated with worse outcomes. However, it is unknown whether the interaction between obesity and COPD modulates diaphragm shape and consequently its function. The body mass index has been used as a correlate of obesity. We tested the hypothesis that the shape of the diaphragm muscle and size of the ring of its insertion in Non-COPD and COPD subjects are modulated by BMI. METHODS: We recruited 48 COPD patients with post-bronchiodilator FEV1/FVC < 0...

Mesenchymal hamartoma of the chest wall is a well-recognized but extremely rare entity. This entity is believed to be benign with no propensity for invasion or metastasis. Although the lesion manifests with alarming aggressive clinical, radiological, and histological features, it is considered benign and carries an excellent outcome. Therefore it is important to recognize this benign entity to avoid the possible misdiagnosis of malignancy and the unnecessary use of chemotherapy. We present a case of bilateral multifocal mesenchymal hamartomas of the chest wall in a male infant and a literature review of this entity...

INTRODUCTION: Normal tissue complications following chest wall radiotherapy (RT) are inevitable, and the long-term data on hypofractionation are still limited. To quantify the late effects of hypofractionated RT on cardiac, pulmonary, brachial plexus, and regional lymphatics and their correlation with patient, tumor, and treatment characteristics is the main objective of this study. MATERIALS AND METHODS: Two hundred and sixteen breast cancer patients following mastectomy were treated with hypofractionated schedules either 40 Gy in 15 fractions or 42...

An estimated 45 million persons in Europe are annually subjected to sleep-wake disorders. State-of-the-art polysomnography provides sophisticated insights into sleep (patho)physiology. A drawback of the method, however, is the obtrusive setting dependent on a clinical-based sleep laboratory with high operational costs. A contact-less prototype was developed to monitor limb movements and vital signs during sleep. A dual channel K-band Doppler radar transceiver captured limb movements and periodic chest wall motion due to respiration and heart activity...

BACKGROUND: Free jejunal transfer has a high success rate, but if vascular thrombosis occurs, the salvage of failing flap with reanastomosis is difficult. This study described a combined deltopectoral (DP) and pectoralis major musculocutaneous (PMMC) flap 2-step technique for cervical esophageal reconstruction after free-jejunal-flap necrosis. METHODS: In step 1, the detection of free jejunal flap with the subsequent debridement of necrotic and infected tissue was followed by the construction of external fistula on the pharyngeal side with the hole in cervical skin and the construction of another external fistula on the esophageal side and tracheal stoma with a single or double DP flap...
