Digital visualization in 3-D of cervical nerves in a healthy person

High-resolution multilayer X-ray computer tomography and 3.0T superconducting magnetic resonance myelography are known to obtain a more complete and continuous two-dimensional original data.

Three-dimensional reconstruction nerve models are classically obtained from two-dimensional images of "visible human" frozen sections. However, because of the flexibility of nerve tissues and small color differences compared with surrounding tissues, the integrity and validity of nerve tissues can be impaired during milling.

Jiaming Fu and colleagues from the 98 Hospital of Chinese PLA successfully developed a three-dimensional digital visualization model of healthy human cervical nerves, which overcomes the disadvantages of milling, avoids data loss, and exhibits a realistic appearance and three-dimensional image. Furthermore, vivid images from various angles can be observed due to minimal pattern distortion. This model revealed the morphology, distribution, and spatial relations of the major nerves of the neck, and provided three-dimensional morphological data for anatomical teaching and morphological observation of regenerated nerves, nerve block anesthesia, and surgery.

These results are published in Neural Regeneration Research (Vol. 8, No. 20, 2013).

Cervical cancer screening and treatment are neglected in low- and middle-income countries

Cervical cancer screening and treatment are neglected in low- and middle-income countries

While there have been substantial improvements in mortality rates and an increase in access to reproductive health interventions in low- and middle-income countries (LMICs), the global health community is neglecting prevention, screening, and treatment for cervical cancer in LMICs. These are the conclusions of a new article in PLOS Medicine this week by Ruby Singhrao and colleagues from the University of California San Francisco, San Francisco.

Using a framework including equity and socio-economic, gender, public health, and health services dimensions, the authors propose four arguments for why cervical cancer screening and treatment should be included as part of the "post-2015 development agenda," for improving reproductive and maternal health outcomes. They argue that the burden of cervical cancer falls on women of reproductive age and that cervical cancer is associated with reduced reproductive capacity. Furthermore, cervical cancer screening and treatment can be integrated into other health services and recent evidence demonstrates that HPV vaccination can protect girls from pre-cancerous lesions.

"For cervical cancer, we fortunately now have a wide range of feasible, affordable, and effective prevention options, which make dramatic global reductions in cervical cancer incidence a realistic goal in our lifetime", conclude the authors.
