Nicholas E Protonotarios, George M Spyrou, George A Kastis
The problem of determining the contours of objects in nuclear medicine images has been studied extensively in the past, however most of the analysis has focused on a single object as opposed to multiple objects. The aim of this work is to develop an automated method for determining the contour of multiple objects in positron emission tomography (PET) and single photon emission computed tomography (SPECT) filtered backprojection (FBP) reconstructed images. These contours can be used for computing body edges for attenuation correction in PET and SPECT, as well as for eliminating streak artifacts outside the objects, which could be useful in compressive sensing reconstruction...

BACKGROUND: Pectus excavatum (PE) is one of the most frequent thoracic malformations. Generally, the malformation is not associated with functional disorders and often constitutes an aesthetic alteration with significant psychological distress. OBJECTIVES: To reduce the visibility of the residual scarring produced by corrective surgery and to improve the aesthetic outcome, the authors propose a new prosthetic implant technique through a periareolar access. METHODS: From January 2005 to January 2015, 11 patients affected with PE underwent the surgical procedure with a sternal prosthesis implanted through a periareolar access with the help of a fiberscope...

Follicular carcinoma of thyroid is the second most common type of carcinoma of thyroid, and it may metastasize to bone, lung, brain, and skin. However, the initial presentation of follicular carcinoma of the thyroid as a large intrathoracic mass without any symptoms of thyroid gland enlargement and dysfunction is very rare. We hereby report a case of a 50-year-old male who presented with chief complaints of chest and low back pain. Preliminary evaluation led to the provisional diagnosis of left-sided intrathoracic mass with vertebral metastasis which was suspected to be a case of bronchogenic carcinoma with distant metastasis...

Radiation therapy is widely used for thoracic cancers. However, it occasionally causes radiation-induced lung injuries, including pneumonitis and fibrosis. Chung-Sang-Bo-Ha-Tang (CSBHT) has been traditionally used to treat chronic pulmonary disease in Korea. PM014, a modified herbal formula derived from CSBHT, contains medicinal herbs of seven species. In our previous studies, PM014 exhibited anti-inflammatory effects in a chronic obstructive pulmonary disease model. In this study, we have evaluated the effects of PM014 on radiation-induced lung inflammation...

BACKGROUND: Congenital diaphragmatic hernia (CDH) is a severe congenital anomaly. The observed to expected lung area-to-head circumference ratio (o/e-LHR) has been shown to provide a useful prediction of subsequent survival in fetuses with CDH in reference centers with expertise and a large caseload. However, the accuracy of o/e-LHR measurements in unselected fetal medicine units or in centers with less expertise is not well known. OBJECTIVE: To evaluate o/e-LHR measurement in prognostic evaluation of postnatal survival when the measurement is performed in fetal medicine units with different levels of expertise...

INTRODUCTION: Surgical treatment of Grade III gynecomastia generally utilizes mastectomy techniques and free transplantation of the nipple-areola complex. Moreover, with rising obesity rates and the development of bariatric surgery, an increasing demand for correctional surgery for pseudogynecomastia has been observed, which is comparable to Grade III gynecomastia in terms of its surgical management. Here, we describe an innovative technique to deal with these new demands: fascio-cutaneous flap by postero-inferior pedicle...
