Combining prior day contours to improve automated prostate segmentation.
Conclusions: Combining the plan and all prior days via the STAPLE algorithm to produce treatment day contours is superior to the current standard of deforming only the plan contours to the daily CBCT. STAPLE also improves the precision, with a substantial decrease in standard deviation, a key for adaptive therapy. Geometrically and dosimetrically accurate contours can be automatically generated with STAPLE on prostate region kV CBCT in a time scale suitable for online adaptive therapy.

Noninvasive evaluation of vaginal fibrosis following radiotherapy for gynecologic malignancies: A feasibility study with ultrasound B-mode and Nakagami parameter imaging.
Conclusions: Vaginal fibrosis appears to be associated with a thickened vaginal wall, higher echogenicity, as well as increased Nakagami PDF and shape parameters. This pilot study shows the authors' quantitative ultrasound approach combining B-mode and Nakagami imaging is a promising imaging method to evaluate vaginal fibrosis. This imaging method may be useful as physicians try to address vaginal toxicities and sexual dysfunction in women after radiotherapy for GYN malignancies. PMID: 23387772 [PubMed - in process]

Case report: misdiagnosis of tailgut cyst presenting as recurrent perianal fistula with pelvic abscess
We describe a case of a 16-year-old female who presented with pelvic pain. She had previously undergone several procedures at an outside institution for recurrent perianal fistula and perirectal abscess. Subsequent evaluation under anesthesia revealed a presacral cystic mass with a well-developed tract within the anorectal ring in the posterior midline. This mass was surgically removed using a combined transanal and posterior sagittal excision technique and was found to be a tailgut cyst upon pathologic evaluation. Tailgut cysts and other presacral masses should be included in the differential for patients with recurrent a...

A Morphometric Study of the Semicircular Canals Using Micro‐CT Images in Three‐Dimensional Reconstruction
It is generally accepted that the three semicircular canals are set at right angles to each other and the lateral semicircular canal is smaller than the anterior and posterior semicircular canals. Precise knowledge of the size and spatial relationships of the semicircular canals is vital, and so the 40 petrous parts of the temporal bones were scanned by micro‐CT at a slice thickness of 35 µm. The micro‐CT images were used in reconstructing three‐dimensional models of the bony labyrinth using computer software. Various dimensions of the semicircular canals were measured using the software, and statistical analysis wa...

Marcello Malpighi and the discovery of the pulmonary capillaries and alveoli.
Abstract Marcello Malpighi (1628-1694) was an Italian scientist who made outstanding contributions in many areas including the anatomical basis of respiration in amphibia, mammals and insects, and also in the very different fields of embryology and botany. He was one of the first biologists to make use of the newly-invented microscope, and is best known as the discoverer of the pulmonary capillaries and alveoli. However he also discovered the spiracles and tracheae that enable respiration in insects. His studies of the embryology of the chicken were far ahead of his time, and he then turned to the anatomy of plants...

Accuracy and complications associated with the freehand C-1 lateral mass screw fixation technique: a radiographic and clinical assessment.
Conclusions The technique for freehand C-1 LMS fixation appears to be safe and effective without intraoperative fluoroscopy guidance. Preoperative planning and determination of the ideal screw insertion point, the ideal trajectory, and screw length are the most important considerations. In addition, fewer malpositioned screws were inserted as the study progressed, suggesting a learning curve to the technique. PMID: 23373564 [PubMed - as supplied by publisher]

Technical nuances for surgery of insular gliomas: lessons learned.
Abstract Insular gliomas were traditionally considered a nonsurgical entity due to the high morbidity associated with resection. For the past 20 years, advances in microsurgical and brain mapping techniques have allowed neurosurgeons to resect insular gliomas with acceptable morbidity rates. Maximizing the extent of resection is nowadays the goal of surgery since this has proven to be an independent factor contributing to longer survival. Despite much progress, insular tumors remain a challenge for the neurosurgeon due to the complex anatomy of the region and technical expertise required to minimize morbidity durin...

Preventing L5-s1 discitis associated with sacrocolpopexy.
CONCLUSION: : In the supine position, the most prominent structure in the presacral space is the L5-S1 disc, which extends approximately 1.5 cm cephalad to the "true" sacral promontory. During sacrocolpopexy, awareness of a 60-degree average drop between the anterior surfaces of L5 and S1 vertebra should assist with intraoperative localization of the sacral promontory and avoidance of the L5-S1 disc. The first sacral nerve can be expected approximately 3 cm from the upper surface of the sacrum and 1.5 cm from the midline. LEVEL OF EVIDENCE: : II. PMID: 23344278 [PubMed - in process]

Pharmacology 2.0
Pharmacology occupies an unusual position within the life sciences: unlike physiology, biochemistry or anatomy for example, it wouldn't have a function at all if we didn't take medicines or drugs. Of course, clinical practice today without such resources is inconceivable. Drugs constitute one of the principal ways of combating and mitigating disease: according to the ABPI (2011), over a thousand million prescriptions are written each year in the UK averaging some 20 per head of the population [1]. Biological organisms are intricate chemical machines. As the cosmologist Martin Rees has noted [2], we know more about what goe...

Three Dimensional Computed Tomography Lung Modeling is Useful in Simulation and Navigation of Lung Cancer Surgery.
Abstract The number of minimally invasive operations, such as video-assisted thoracoscopic surgery (VATS) lobectomy or segmentectomy, has enormously increased in recent years. These operations require extreme knowledge of the anatomy of pulmonary vessels and bronchi in each patient, and surgeons must carefully dissect the branches of pulmonary vessels during operation. Thus, foreknowledge of the anatomy of each patient would greatly contribute to the safety and accuracy of the operation. The development of multi-detector computed tomography (MDCT) has promoted three dimensional (3D) images of lung structures. It is...

Relationship of the Intercondylar Roof and the Tibial Footprint of the ACL: Implications for ACL Reconstruction
Conclusion: The tibial footprint of the ACL is located in a position on the tibia that is consistent and does not vary according to intercondylar roof angle. The cACL is consistently located between 43.2% and 45.0% of the anteroposterior length of the tibia. Intercondylar roof–based guidance may not predictably place a tibial tunnel in the native ACL footprint. Use of a generic ACL footprint to place a tibial tunnel during ACL reconstruction may be reliable in up to 95% of patients.

Lumbar vertebral body bone microstructural scaling in small to medium-sized strepsirhines.
Abstract Bone mass, architecture, and tissue mineral density contribute to bone strength. As body mass (BM) increases any one or combination of these properties could change to maintain structural integrity. To better understand the structural origins of vertebral fragility and gain insight into the mechanisms that govern bone adaptation, we conducted an integrative analysis of bone mass and microarchitecture in the last lumbar vertebral body from nine strepsirhine species, ranging in size from 42 g (Microcebus rufus) to 2,440 g (Eulemur macaco).

How to simplify the approach to the supra-aortic trunks.
Abstract Carotid artery stenting (CAS) represents a valid alternative to carotid endarterectomy (CEA). Possible embolization during the approach and the cannulation of the supra-aortic arterial trunks remains an important obstacle to CAS. This risk is increased in elderly patients and complex anatomies. In order to achieve satisfactory technical and clinical outcomes, a thorough understanding of the patients' individual anatomy of the arch and the access vessels is essential. The cannulation of the common carotid artery represents the key maneuver for the entire CAS procedure. This review article will present the c...

Carotid artery stenting with filters.
Abstract Filters are a valuable aid for safe carotid artery stenting, but require good knowledge of their function, and their shortcomings. Filters capture visible particles in 5-20% and microscopically in about 70% of the cases. Transcranial Doppler ultrasound and diffusion weighted MRI investigations have shown that particles are released during filter placement and also during the next steps of the procedure. They can pass through the filter pores when they are small enough and through unprotected areas when the filter is not completely apposed to the arterial wall. Therefore, they do not reliably prevent transi...

Modeling Secondary Messenger Pathways in Neurovascular Coupling.
We present a model of intracellular calcium dynamics in an astrocyte (glial cell) and show that stable oscillatory behaviour is possible under certain conditions. We then couple this to a novel model for the relationship between calcium concentration and the production of vasoactive secondary messengers through a fatty-acid intermediate. The two secondary messengers modelled are epoxyeicosatrienoic and 20-hydroxyeicosatetraenoic acids (EET and 20-HETE, respectively). These secondary messengers are produced on different time scales, and we show how this supports the observation that the vasculature dilates rapidly in respon...

Transverse cervical nerve: Implications for dental anesthesia
The inferior alveolar nerve block (IANB) has the highest failure incidence of any dental anesthetic technique. Many authors have outlined potential reasons for these failures in permanent lower molars, including accessory innervations from the mylohyoid and mental foramen. However, the potential accessory innervation of posterior mandibular teeth from the transverse cervical nerve (TCN), a branch of ventral rami from the C2–C3 spinal nerves from the cervical plexus (CP), has been difficult to assess as a result of the small size and thickness of the mandibular accessory foramina and nerve branches, as well as due to the ...

Measuring distortion of skeletal elements in Lodox Scatscan‐generated images
Due to a scarcity of available skeletal material, anthropologists and other practitioners face difficulties with either the creation or validation of techniques used to estimate a biological profile in subadults. To address this problem, radiographic images of living individuals are often used in lieu of dry skeletal elements. However, radiographic images suffer from distortion. Some problems with metric analyses when using radiographic images may be addressed with the Lodox Statscan, an X‐ray machine that claims to produce minimal distortion along the scan‐axis due to a linear slot‐scanning design.
