Staged surgery for irregular giant pituitary adenomas: A report of two cases.

The resection of giant pituitary adenomas is one of the most challenging brain surgeries, especially when the giant pituitary adenomas have an irregular shape or irregular growth position. The purpose of the present study is to propose staged surgery for irregular giant pituitary adenomas through a retrospective analysis of two cases. The cases of two patients with irregular giant pituitary adenomas who underwent staged surgery are retrospectively analyzed.

Surgical treatment of severe scoliosis and kyphoscoliosis by stages.

Background: Although previous reports had reported the use of temporary internal distraction as an aid to correct severe scoliosis, two-stage surgery strategy (less invasive internal distraction followed by posterior correction and instrumentation) has never been reported in the treatment of patients with severe spinal deformity. This study aimed to report the results of the surgical treatment of severe scoliosis and kyphoscoliosis by two-stage and analyse the safety and efficacy of this surgical strategy in the treatment of severe spinal deformities.

Methods: A total of 15 patients with severe scoliosis, kyphoscoliosis or kyphosis who underwent two-stage surgeries (less invasive internal distraction followed by posterior correction and instrumentation) were studied based on hospital records.

[Balloon inflating and cement filling for treatment of avascular necrosis of the femoral head: a three-dimensional infinite-element study].

Objective: To evaluate the biomechanical changes of balloon inflating and cement filling in avascular necrosis of the femoral head using finite-element analysis.

Methods: The procedure of percutaneous balloon inflating and cement filling was simulated in fresh specimen of human femoral head. CT scan and three-dimensional reconstruction were used to establish the three-dimensional model of the femoral head.

[Clinical application of posterior paramedian approach in low back surgeries].

Objective: To prospectively evaluate the clinical effects of posterior paramedian approach in nerve root decompression and reducing muscle damage in low back surgeries.

Methods: Study group included 30 cases treated from January 2007 to May 2008, DDD 8 cases, spondylolisthesis 6 cases, LDH 11 cases, Low back surgery failure re-operation 5 cases. Based on the comprehensive understanding of modern spine anatomy, we abandoned laminectomy in our procedure, applied a mid-waist skin incision, dissect to the paraspinal muscles where you could easily reach the facets by separating between the multifidus and longissimus, enlarge the canal by performing resection along ligamentum flavum and the inner broader of the articular process, remove enough tissue till you could expose the traversing root and the disc space, this method could achieve a limited but precise and effective decompression with not taking out all of the articular process.

[Kyphoplasty for treatment of non-osteoporotic thoracolumbar compressive fractures: analysis of 17 cases].

Objective: To evaluate the efficacy and safety of kyphoplasty for treatment of non-osteoporotic compressive fractures of thoracolumbar vertebrae.

Methods: Seven patients of non-osteoporotic thoracolumbar compressive fractures confirmed by plain X-ray examination and CT scanning, 14 males and 3 females, aged 35.2, all suffering from one level fracture, at T9 in 1 case, T11 in 2 cases, T12 in 7 cases, L1 in 5 cases, L2 in 1 case, and L3 in 1 case were.

Balloon kyphoplasty: an experience of 38 patients with painful osteoporotic vertebral compressive fractures.

Objective: To evaluate the efficacy and safety of percutaneous balloon kyphoplasty as a new therapy for patients with painful osteoporotic vertebral compressive fractures of the lumbar and thoracic spine.

Methods: A retrospective analysis was conducted in 38 consecutive patients (28 females, 10 males), whose ages ranged from 56 to 82 years (mean age 72 years). The symptom- and sign-positive spinal segment was identified by MRI.

[Characteristic of medical support and health care for Shenzhou-5 and Shenzhou-6 astronauts at main landing site].

Objective: To investigate the characteristics of medical support and health care for the Shenzhou-5 and Shenzhou-6 astronauts at the main landing site, with special emphasis on the technical requirements for two astronauts during flight, in order to provide reference data for medical support in the battle field and disasters.

Methods: The data associated with accidental injuries of astronauts during the space flight collected from foreign nations and domestically were reviewed retrospectively. Based on the experience in medical support for Shenzhou-5 and Shenzhou-6 astronauts and the special environments of field operations, a scheme for first-aid and emergent treatment were drafted for a system of organization, prophylactic measurements, equipment and their effective implementation pending the test in the real situation.

[Selection of surgical procedure for the treatment of idiopathic scoliosis].

Objectives: To discuss and evaluate the selection of surgical procedure for the treatment of idiopathic scoliosis according to the location and degree of the deformity.

Methods: 175 patients with idiopathic scoliosis underwent surgical treatment with correction and fusion. The patients were divided into four groups according to the location and degree of the deformity and four different procedures were used for each group.

[Establishment of a mobile intensive care unit].

Objective: To discuss the experience of establishment of a mobile intensive care unit (ICU) for emergency treatment following astronaut flight, disaster, and regional war.

Methods: The data from both foreign and our countries as well as our own clinical experience of first-aid were reviewed, and a mobile ICU was established, including the equipment, supply of drugs, training, and organization.

Results: The mobile ICU was set up at the site of landing of the first Chinese astronaut, and proved to be efficient.

[Measure on medical care and rescue for the first Chinese astronaut during manned space flight].

Objective: To discuss the experience of medical care and rescue for the first Chinese astronaut during manned space flight.

Methods: Review the experiences of foreign nations in respect to accidental injuries of astronaut during manned space flight, the possible reasons were analyzed, and accordingly a reasonable and effective prophylactic measures and health care were formulated.

Results: An effective mobile intensive care unit (ICU) was established on desert or prairie where the capsule would land, so as to ensure the safety of the first Chinese astronaut, and to provide intensive care as well as successful emergency treatment in case of accidental injuries.
