Although off-label, the use of Pramipexole as an adjunct therapy in treatment resistant depression has recently been documented in the literature with promising results. We present a 75-year-old male with MDD who has failed trials of SSRIs, SNRIs, TCAs, SGA, TMS, Ketamine, and ECT who was initiated on Pramipexole. We discuss, based on existing literature, the probability of a favorable long-term response to Pramipexole and the potential side effects for our patient. We also highlight the need for future studies designed to test the efficacy of Pramipexole in geriatric patients with TRD.展开更多

The modern advance in treatment of endometriosis management is tackling the debilitating pain it causes, besides the infertility in patients desiring fertility in reproductive age group. This can be achieved by surgical or medical means, although in most cases a combination of both treatments is required. Usually, long term treatment is required in most cases. Unfortunately in most cases, pain symptoms recur between 6months and 12 months once treatment is stopped. A lot of research has gone in understanding the pathogenesis and further medical management of endometriosis besides surgery to be useful in relieving pain and use in patients desiring fertility besides hormonal treatments used earlier like hormonal contraceptives (oral, transdermal or vaginal administration), progestogens, danazol, Gonadotrophic releasing hormone agonist (GnRH), aromatase inhibitors. Newer agents like antiangiogenic drugs, phytochemical agents like resveratrol, TNF-α inhibitors, GnRH antagonists like egalogolix, statins, antiinflammatory agents like COX2 Inhibitors and PPARγ inhibitors like pioglitazone etc., with recent work of combined efficacy of telmesartan of both PPARγ partial agonism along with angiotensin 1 receptor agonism having more efficacy, role of immunomodulators like rapamycin, lipoxin 4 and pentoxyphylline, GnRH antagonists like egalogolix are still under study undergoing phase III trials although preliminary results show promising results with fewer side effects as compared to similar duration of GnRH agonist and much less BMD side effects. Increasing number of trials show the safety of SPRM’s, along with efficacy although disadvantage is suppression of fertility so cannot be used for women desiring fertility. Currently, only mifepristone and ulipristal have received FDA approval for indication in fibroid treatment, MTP and not for endometriosis as yet. The advantages and disadvantages of all the recent advances are discussed in an update in the pathophysiology as well medical treatment of endometriosis.展开更多
