Retrospective analysis of atlantoaxial rotatory fixation describing age distribution and gender ratio in children and adolescents: A preliminary report.

Introduction: Atlantoaxial rotatory fixation (AARF) in children presents with an acute onset of neck pain. Almost all cases heal within a few days of onset and are treated conservatively. Because few cases of AARF have been reported, the age distribution or gender ratio of AARF in the child population have not been described enough.

Cost-minimization analysis of adjuvant chemotherapy regimens given to patients with colorectal cancer in Japan.

Background: Consideration of medical costs as well as effectiveness and adverse events is rapidly been becoming an important factor in the selection of chemotherapy regimens. However, practical data on the costs of chemotherapy are scarce. We clinically estimated the medical costs of 6 adjuvant chemotherapy regimens for colorectal cancer on the basis of clinical and cost-related data and compared their cost-effectiveness by cost-minimization analyses.

[Abnormal Low Blood Pressure after Induction of General Anesthesia in a Patient on Medication for Depression].

A patient under medication for depression underwent orthopedic surgery for osteoarthritis of the knee four times. For the second surgery, general anesthesia was induced with propofol, remifentanil, and rocuronium. Immediately after induction, she developed severe hypotension that was resistant to vasopressors.

The dose-dependent effects of isoflurane on outcome from severe forebrain ischemia in the rat.

Isoflurane improves outcome against cerebral ischemia in the rat. However, the optimal neuroprotective concentration has not been defined. We examined the effects of different isoflurane concentrations on outcome from severe forebrain ischemia in the rat.

[Tension pneumothorax manifested after extubation in a patient who underwent total gastrectomy].

A patient developed tension pneumothorax immediately after extubation. The patient was a 53-year-old man, who underwent total gastrectomy under general anesthesia combined with epidural anesthesia. The posterior mediastinum drainage tube was placed near the site of esophago-jejunum anastomosis.
