Transzygomatic anterior infratemporal fossa approach and high cervical approach for resection of infra temporal fossa and parapharyngeal space solitary fibrous tumours: Report of 2 cases and review of literature
The infratemporal fossa (ITF) is the region under the floor of the middle fossa giving passage to most major cerebral vessels and cranial nerves.(1) It is closely related to important adjacent regions such as the middle fossa, pterygopalatine fossa, orbit, and nasopharynx.(2) Due to the anatomical complexity in the ITF, surgical removal of the lesions in or around it is still challenging.(3) Since the 1960s, many surgeons have reported various surgical approaches. the preauricular transzygomatic approach via a transcranial route was reported to be used for exposure of the antero-superior portion of the ITF (2,3). Solitary fibrous tumours (SFTs) were first described by Klempere and Rabin in 1931 as spindle-cell tumours originating from the pleura.(4) With the exception of myopericytoma, infantile myofibromatosis and HPC-like lesions of the sinonasal tract showing myoid differentiation, all other HPC like lesions are best considered as subtypes of SFT.(5) Only a few cases of SFT have been described in the literature involving the skull base and parapharyngeal space.(6–8) The purpose of this article is to show anatomical dissections involving this surgical approach and to evaluate our surgical experience using it
LCrowdV: Generating Labeled Videos for Simulation-based Crowd Behavior Learning
We present a novel procedural framework to generate an arbitrary number of
labeled crowd videos (LCrowdV). The resulting crowd video datasets are used to
design accurate algorithms or training models for crowded scene understanding.
Our overall approach is composed of two components: a procedural simulation
framework for generating crowd movements and behaviors, and a procedural
rendering framework to generate different videos or images. Each video or image
is automatically labeled based on the environment, number of pedestrians,
density, behavior, flow, lighting conditions, viewpoint, noise, etc.
Furthermore, we can increase the realism by combining synthetically-generated
behaviors with real-world background videos. We demonstrate the benefits of
LCrowdV over prior lableled crowd datasets by improving the accuracy of
pedestrian detection and crowd behavior classification algorithms. LCrowdV
would be released on the WWW
Pulmonary Sclerosing Hemangioma Detected by Fluorodeoxyglucose Positron Emission Tomography in Familial Adenomatous Polyposis: Report of a Case
We present a 53-year-old female suffering from familial adenomatous polyposis, who was found to have a positive nodus, lateral to the hilus of the left lung, on routine FDG-PET scan. This lesion was found to be a sclerosing hemangioma. We found an aberrant β-catenin expression on immunohistochemical staining, suggesting that sclerosing hemangioma and familial adenomatous polyposis share the same pathophysiology. It is important to be aware of the association of familial adenomatous polyposis and sclerosing hemangioma

Analysis of comorbid factors that increase the COPD assessment test scores
Background: The chronic obstructive pulmonary disease (COPD) Assessment Test (CAT) is a concise health status
measure for COPD. COPD patients have a variety of comorbidities, but little is known about their impact on quality of life. This study was designed to investigate comorbid factors that may contribute to high CAT scores.
Methods: An observational study at Keio University and affiliated hospitals enrolled 336 COPD patients and 67
non-COPD subjects. Health status was assessed by the CAT, the St. Georges Respiratory Questionnaire (SGRQ), and
all components of the Medical Outcomes Study Short-Form 36-Item (SF-36) version 2, which is a generic measure
of health. Comorbidities were identified based on patients’ reports, physicians’ records, and questionnaires,
including the Frequency Scale for the Symptoms of Gastro-esophageal reflux disease (GERD) and the Hospital
Anxiety and Depression Scale. Dual X-ray absorptiometry measurements of bone mineral density were performed.
Results: The CAT showed moderate-good correlations with the SGRQ and all components of the SF-36. The presence
of GERD, depression, arrhythmia, and anxiety was significantly associated with a high CAT score in the COPD patients.
Conclusions: Symptomatic COPD patients have a high prevalence of comorbidities. A high CAT score should alert the clinician to a higher likelihood of certain comorbidities such as GERD and depression, because these diseases may co-exist unrecognize
