According to long-term follow-up findings, giant prolactinomas are exquisitely responsive to dopamine agonist therapy. In giant prolactinomas the prolactin level does not correlate with size. The main indication for early surgery is intratumoral hematoma, whereas our main indications for late surgery are cerebrospinal fluid leakage caused by medical treatment, or an increasing prolactin level despite medical therapy. Checking prolactin levels in suspicious sellar and/or suprasellar lesions may be diagnostic and prevent unnecessary surgery.
This study showed an increased incidence of nonunion (18.2%) and postsurgical cage migration (18.2%) in patients undergoing TLIF with biodegradable cages versus carbon fiber implants (0%) (p = 0.006 and 0.007, respectively).
The authors describe a case of paraspinal calcinosis in a 65-year-old woman with progressive systemic sclerosis. Although calcinosis occurs in up to 27% of cases of progressive systemic sclerosis, symptomatic paraspinal calcinosis is extremely rare. In the case reported here, multiple cervical facet joints were compromised by progressive calcinosis, leading to glacial spinal instability. Internal fixation was indicated to correct the instability and decompress the spinal canal. Medical therapy was instituted to arrest or reverse the ongoing calcinosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
