Epidemiology of drug resistant HIV has focused on trends and less attention has been given to identification of factors, especially behaviors including substance use, in acquisition of drug-resistant HIV. From 2009 to 2012 The Metromates Study enrolled and followed for one year men who have sex with men (MSM) seeking testing for HIV in a community clinic in Los Angeles assessing those testing positive for acute and recent HIV infection. Behavioral data were collected via Computer-Assisted Self-Interview from 125 classified as newly HIV infected and 91 as chronically infected (newly HIV-diagnosed); specimens were available and viable for resistance testing for 154 of the 216 HIV positives with new diagnoses...

BACKGROUND AND OBJECTIVE: A high percentage of medical errors, committed because of physician's lack of experience, huge volume of data to be analyzed, and inaccessibility to medical records of previous patients, can be reduced using computer-aided techniques. Therefore, designing more efficient medical decision-support systems (MDSSs) to assist physicians in decision-making is crucially important. Through combining the properties of fuzzy logic and neural networks, fuzzy cognitive maps (FCMs) are among the latest, most efficient, and strongest artificial intelligence techniques for modeling complex systems...

Thymic carcinoma is a rare cancer, accounting for only 1% to 4% of thymic epithelial tumors. Endobronchial metastasis is a rare presentation of these tumors. A 64-year-old man presented with a cough. Lung cancer was suspected because a chest radiograph showed a 7-cm mass in the left pulmonary hilum. Computed tomography showed a mass in the anterior mediastinum and an infiltrate in the upper lobe of the left lung. Bronchoscopy demonstrated bilateral polypoid tumors in the left B bronchus and the right B bronchus...

BACKGROUND: Investigation of brain cancer can detect the abnormal growth of tissue in the brain using computed tomography (CT) scans and magnetic resonance (MR) images of patients. The proposed method classifies brain cancer on shape-based feature extraction as either benign or malignant. The authors used input variables such as shape distance (SD) and shape similarity measure (SSM) in fuzzy tools, and used fuzzy rules to evaluate the risk status as an output variable. We presented a classifier neural network system (NNS), namely Levenberg-Marquardt (LM), which is a feed-forward back-propagation learning algorithm used to train the NN for the status of brain cancer, if any, and which achieved satisfactory performance with 100% accuracy...

Molecular pathology, especially immunohistochemistry, plays an important role in evaluating hormone receptor status along with diagnosis of breast cancer. Time-consumption and inter-/intraobserver variability are major hindrances for evaluating the receptor score. In view of this, the paper proposes an automated Allred Scoring methodology for estrogen receptor (ER). White balancing is used to normalize the colour image taking into consideration colour variation during staining in different labs. Markov random field model with expectation-maximization optimization is employed to segment the ER cells...

Antibody-mediated rejection is associated with heterogeneous kidney allograft outcomes. Accurate evaluation of risk for graft loss at time of diagnosis is necessary to offer personalized treatment. In contrast with serological and molecular assessment, morpho-histological evaluation of antibody-mediated rejection lesions has not significantly evolved. This relies on Banff classifications designed to be of diagnostic discriminatory power rather than prognostic and face quantitative and qualitative limitations...

BACKGROUND: Localizing small or deep pulmonary nodules or subsolid ground-glass opacities often is difficult during video-assisted thoracoscopic surgery (VATS) or robotic-assisted thoracoscopic surgery (RATS). This can result in larger resections or conversion to thoracotomy. The goal of this study is to evaluate the role of electromagnetic navigational bronchoscopic localization (ENBL) as a safe and accurate intraoperative method to localize small, deep, or subsolid nodules. METHODS: This is a single-institution, single-surgeon retrospective study of all patients (51) who underwent combined ENBL and resection of 54 nodules between May 2013 and August 2015...

This review covers computer-assisted analysis of images in the field of medical imaging. Recent advances in machine learning, especially with regard to deep learning, are helping to identify, classify, and quantify patterns in medical images. At the core of these advances is the ability to exploit hierarchical feature representations learned solely from data, instead of features designed by hand according to domain-specific knowledge. Deep learning is rapidly becoming the state of the art, leading to enhanced performance in various medical applications...

This case describes successful reconstruction of a long-segment tracheal defect using AlloDerm as the conduit for reconstruction. A 38-year-old woman who had undergone a thyroid lobectomy in 2011 presented several months later unable to swallow. Chest computed tomography results revealed a tracheal/esophageal mass and a subsequent bronchoscopy, and esophagogastroduodenoscopy results revealed an upper esophageal/tracheal mass with two areas concerning for fistula. She underwent a bronchoscopy with a tracheal stent and percutaneous endoscopic gastrostomy placement...

Over the last 15 years, cone beam computed tomographic (CBCT) imaging has emerged as an important supplemental radiographic technique for orthodontic diagnosis and treatment planning, especially in situations which require an understanding of the complex anatomic relationships and surrounding structures of the maxillofacial skeleton. CBCT imaging provides unique features and advantages to enhance orthodontic practice over conventional extraoral radiographic imaging. While it is the responsibility of each practitioner to make a decision, in tandem with the patient/family, consensus-derived, evidence-based clinical guidelines are available to assist the clinician in the decision-making process...

RATIONALE: Communicating bronchopulmonary foregut malformation (CBPFM) is a rare congenital malformation involving both the digestive and respiratory systems. To our best knowledge, most cases of CBPFM reported in the literature were in infancy or adulthood and CBPFM in infantile is even rarer with a high case-fatality rate partly due to misdiagnosis. PATIENT CONCERNS: We presented 2 cases of neonatal CBPFM. A 11-hour male newborn was admitted because of moaning for 7 hours, and a 1-day male newborn was referred to us with profuse foams, choking on breast-milk feeding and facial cyanosis...

Diagnosis and preoperative planning are critical in the execution of any surgical procedure. Panoramic radiography is a routine method used in dentistry to assist clinical diagnosis; however, with this technique 3D anatomical structures are compressed into 2D images, resulting in overlapping of structures which are of interest in the diagnosis. In this study we report the case of a patient who presented with a dentigerous cyst of expressive dimensions in the body of the mandible region. The surgery was planned and executed after observing the margins of the lesion by Cone Beam Computed Tomography (CBCT)...

An abnormal lung shadow was detected in a 39-year-old woman at physical examination and she was followed-up carefully at a nearby hospital. After 5 years follow-up, the patient was referred to our hospital for further examination of the abnormal shadow. A chest computed tomography(CT) scan revealed a 12 mm well-circumscribed nodular shadow in the right lower lobe. A benign tumor such as a hamartoma was suspected preoperatively;video-assisted thoracic surgery was performed for both diagnosis and treatment. Partial resection of the right lower lobe was performed and the tumor was diagnosed as an intrapulmonary solitary fibrous tumor (SFT)...

BACKGROUND: The historic association of Actinomyces israelii infection with intrauterine devices (IUDs) has long been recognized. In recent years, the risk of developing pelvic inflammatory disease with a copper or levonorgestrel IUD has been less than 1% in women who are low risk for sexually transmitted infections. IUD-related pelvic infections secondary to actinomyces have largely vanished from contemporary practice. CASE: A 49-year-old using a copper IUD for contraception with poorly controlled type II diabetes mellitus was admitted for suspected tubo-ovarian abscess on the basis of abdominopelvic pain, leukocytosis, and computed tomography findings...

CLINICAL ISSUE: The increased use of highly developed imaging procedures, such as multidetector-row computed tomography and magnetic resonance imaging has led to a substantial increase of asymptomatic and unexpected findings. STANDARD RADIOLOGICAL METHODS: Abdominal CT investigations are particularly affected with a large number of incidental findings. This valuable diagnostic procedure also entails the risk of complex and cost-intensive subsequent investigations with partly invasive procedures...

D Abrantes, P Gomes, D Pereira, M Coimbra
The gastroenterology specialty could benefit from the introduction of Computer Assisted Decision (CAD) systems, since gastric cancer is a serious concern in which an accurate and early diagnosis usually leads to a good prognosis. Still, the way doctors interact with these systems is very important because it will often determine its embracement or rejection, as any gains in productivity will frequently hinge on how comfortable they are with it. Using other types of interaction paradigms such as voice and motion control, is important in a way that typical inputs such as keyboard and mouse are sometimes not the best choice for certain clinical scenarios...

For the early diagnosis and treatment, a needle insertion for biopsy and treatment is a common and important means. To solve the low accuracy and high probability of repeat surgery in traditional surgical procedures, a computer-assisted system is an effective solution. In such a system, how to acquire the accurate orientation of the surgical needle is one of the most important factors. This paper proposes a "Center Point Method" for needle axis extraction with high accuracy. The method makes full use of edge points from two sides of the needle in image and creates center points through which an accurate axis is extracted...
