Effects of Different Positions and Angles of Implants in Maxillary Edentulous Jaw on Surrounding Bone Stress under Dynamic Loading: A Three-Dimensional Finite Element Analysis.

Conclusions: Our models showed optimal stress reductions when the mesial implants were located in the canine region and the distal implants tilted 30°. PMID: 31933678 [PubMed - in process]

ConclusionsThe variability of radiocholine uptake in adrenal glands depends probably on overall body metabolism and hypophyseal function expressed by statistically significant correlation with liver and pituitary gland uptake.Predominant focal or mixed with focal areas uptake patterns on positron emission tomography in normal in computed tomography adrenal glands should be assessed with caution to avoid a diagnostic mistake.

We present abdominal computed tomography and enteroscopy images of a 48-year-old male patient with a previous melanoma who presented with epigastric pain. The pain was not controlled with medical management. Abdominal computed tomography and a histological study of biopsies form enteroscopy confirmed the diagnosis of metastatic melanoma. The gastrointestinal involvement of melanoma is usually metastatic. Symptomatic gastrointestinal involvement occurs in less than 5% of melanomas, although postmortem analyses have reported up to 70%. The clinical presentation is variable and usually presents as abdominal pain. The diagnosi...

Authors: Díaz Alcázar MDM, Ruiz Escolano E, Casado Caballero FJ, Cervilla Sáez de Tejada E Abstract A 72-year-old female presented with abdominal pain and constipation and intestinal dilation was found. Abdominal computed tomography showed two areas of thickening and stenosis in the proximal jejunum and preterminal ileum, with an unknown etiology. Exploratory laparotomy was proposed but the patient suffered a sudden and progressive decrease in consciousness. Cranial computed tomography showed an ischemic area and a midline shift. Brain biopsies suggested infection by Aspergillus Fumigatus. Desp...

CONCLUSION: The authors report an unusual case of ruptured jejunal GIST with hemoperitoneum mimicking ovarian carcinoma. Therefore, GIST, in addition to ovarian cancer, should be considered in patients with an increased serum level of CA-125 and an abdominopelvic mass. PMID: 32055272 [PubMed]

This study aimed to analyse the features of lymphadenopathy and estimate the role of imaging methods, including computed tomography (CT) and positron emission tomography-CT (PET/CT), in the diagnosis of lymphadenopathy in patients with POEMS syndrome. We conducted a retrospective analysis of 23 patients with confirmed POEMS syndrome. All of the patients received chest and abdominal CT scan and/or superficial ultrasound examinations. Four patients underwent PET/CT examinations, and 6 patients received lymph node biopsies. Enlarged lymph nodes (short diameter ≥ 1 cm) were found in 48% (11/23) of patients, but only 1 patie...

Paulson, Kim L. Sandler, Pierre P. Massion, Bennett A. LandmanAbstractWith the rapid development of image acquisition and storage, multiple images per class are commonly available for computer vision tasks (e.g., face recognition, object detection, medical imaging, etc.). Recently, the recurrent neural network (RNN) has been widely integrated with convolutional neural networks (CNN) to perform image classification on ordered (sequ...

METHODS: All consecutive patients undergoing curative surgery for primary lung adenocarcinoma at the Thoracic Surgery Unit of the Un...

Lipoid congenital adrenal hyperplasia (LCAH) is the most severe form of CAH, insofar as the initial step of steroid synthesis is impaired. Variants in the steroid acute regulatory (STAR) gene are responsible for LCAH. To describe the clinical and genetic charac...
