Intraoperative Parathyroid Hormone Monitoring in the Surgical Management of Sporadic Primary Hyperparathyroidism

Intraoperative parathyroid hormone monitoring (IPM) has been shown to be a useful adjunct during parathyroidectomy to ensure operative success at many specialized medical centers worldwide. Using the Miami or “>50% intraoperative PTH drop” criterion, IPM confirms the complete excision of all hyperfunctioning parathyroid tissue before the operation is finished, and helps guide the surgeon to identify additional hyperfunctioning parathyroid glands that may necessitate further extensive neck exploration when intraoperative parathyroid hormone (PTH) levels do not drop sufficiently. The intraoperative PTH assay is also used to differentiate parathyroid from non-parathyroid tissues during operations using fine needle aspiration samples and to lateralize the side of the neck harboring the hypersecreting parathyroid through differential jugular venous sampling when preoperative localization studies are negative or equivocal. The use of IPM underscores the recognition and understanding of sporadic primary hyperparathyroidism (SPHPT) as a disease of function rather than form, where the surgeon is better equipped to treat such patients with quantitative instead of qualitative information for durable long-term operative success. There has been a significant paradigm shift over the last 2 decades from conventional to focused parathyroidectomy guided by IPM. This approach has proven to be a safe and rapid operation requiring minimal dissection performed in an ambulatory setting for the treatment of SPHPT.

A comparative study of injection placentrex and conventional therapy in treatment of pelvic inflammatory disease.

To compare the effect of placentrex injection given along with conventional therapy, with conventional treatment alone on the symptoms and signs of pelvic inflammatory disease (PID) ie, abdominal pain, dysmenorrhoea and adnexal tenderness, 50 out of 100 women with PID were randomly assigned to receive intramuscular placentrex injection along with two-week conventional therapy and 50 received conventional treatment only. Abdominal pain, dysmenorrhoea and adnexal tenderness were evaluated at the end of 2 months. There was marked reduction in the sign of adnexal tenderness in the placentrex group as compared to conventional treatment group (p < 0.001). Subjective symptoms of lower abdominal pain and dysmenorrhoea were also relieved better in placentrex group (p < 0.01 and 0.05 respectively). This study showed significant and persistent improvement of signs and symptoms of PID in women who received injection placentrex.
