piperidines and Retinal-Detachment

The case is presented of a 39-year-old woman with metastatic melanoma treated with dabrafenib and trametinib. She presented with a severe acute panuveitis with granulomatous anterior uveitis, vitritis, and multiple serous retinal detachments. Dabrafenib and trametinib were suspended, and treatment with a systemic and topical corticosteroid was started. A good response was obtained, with a recovery of visual acuity of 1.0 in both eyes within two weeks.. Dabrafenib and trametinib can lead to severe uveitis. Treatment with corticosteroids and discontinuation of therapy with dabrafenib and trametinib led to an anatomical and functional improvement, and resolved the episode rapidly. Ophthalmologists must be aware of this toxicity, given the increasing use of those drugs.

The aim of this study was to investigate how many patients, after anesthesia with either propofol/remifentanil or propofol/fentanyl/alfentanil, within 20 minutes from the end of surgery could be transferred directly to the general ward. The number of undesired preoperative incidents, the anesthetists', the surgeons', and the patients' evaluations of the anesthesia were registered. An evaluation of the economic consequences of the two methods was also intended.. The study was clinically controlled, randomised, and partly blinded. A total of 80 patients undergoing eye surgery were recruited. The patients were scored 10, 15, and 20 minutes after the end of surgery according to a modified Aldrete score. With sufficient awakening score, the patients were transferred to the general ward.. Thirty-six patients in each group underwent the examination. In the propofol/remifentanil-group 31 (86%) could be transferred to the general ward compared to 15 (42%) in the proponol/fentanyl/alfentanil-group. In the propofol/remifentanil-group there were less reactions to the start of surgery, more episodes with preoperative hypotension and postoperative shivering. Otherwise there were no differences between the groups. It was estimated that the additional expenses for medcine were by far outweighed by the lower costs postoperatively.. With a propofol/remifentanil-anesthesia, the patients had a predictably short awakening time, so they could be transferred directly to the general ward. This may, especially in ambulatory surgery, mean cost savings and perhaps higher patient satisfaction.

To report a case of serous macular detachment in a patient with Waldenstrom macroglobulinemia treated with ibrutinib.. The patient underwent a complete ophthalmic examination and imaging at presentation and at follow-up visits up to 13 months.. At presentation, there were serous macular detachments bilaterally with no dye leakage on fluorescein angiography or vasculature abnormalities on optical coherence tomography angiography. After treatment with ibrutinib, there was near resolution of the patient's retinopathy with an improvement in vision at 13 months' follow-up.. Serous macular detachments in Waldenstrom macroglobulinemia-associated retinopathy may be due to the disruption of the retinal pigment epithelium pump mechanism by hyperglobulinemia. The favorable course of this patient, treated with the novel tyrosine kinase inhibitor ibrutinib, suggests this may be the preferred treatment for Waldenstrom macroglobulinemia patients with associated retinopathy.

To investigate the clinical and morphologic characteristics of serous retinal disturbances in patients taking mitogen-activated protein kinase kinase (MEK) inhibitors.. A total of 313 fluid foci in 50 eyes of 25 patients receiving MEK inhibitors for treatment of their metastatic cancer, who had evidence of serous retinal detachments confirmed by optical coherence tomography (OCT).. Single-center, retrospective cohort study.. Clinical examination and OCT were used to evaluate MEK inhibitor-associated subretinal fluid. The morphology, distribution, and location of fluid foci were serially evaluated for each eye. Choroidal thickness was measured at each time point (baseline, fluid accumulation, and fluid resolution). Two independent observers performed all measurements. Statistical analysis was used to correlate interobserver findings and compare choroidal thickness and visual acuity at each time point.. Comparison of OCT characteristics of retinal abnormalities at baseline to fluid accumulation.. The majority of patients had fluid foci that were bilateral (92%) and multifocal (77%) and at least 1 focus involving the fovea (83.3%). All fluid foci occurred between the interdigitation zone and an intact retinal pigment epithelium. The 313 fluid foci were classified into 4 morphologies, as follows: 231 (73.8%) dome, 36 (11.5%) caterpillar, 31 (9.9%) wavy, and 15 (4.8%) splitting. Best-corrected visual acuity at fluid resolution was not statistically different from baseline; and no eye lost more than 2 Snellen lines from baseline at the time of fluid accumulation. There was no statistical difference in the choroidal thickness between the different time points (baseline, fluid accumulation, and fluid resolution). A strong positive interobserver correlation was obtained for choroidal thickness measurements (r = 0.97, P < 0.0001) and grading of foci morphology (r = 0.97, P < 0.0001).. The subretinal fluid foci associated with MEK inhibitors have unique clinical and morphologic characteristics, which can be distinguished from the findings of central serous chorioretinopathy. In this series, MEK inhibitors did not cause irreversible loss of vision or serious eye damage.

Fentanyl was replaced by R 30730/Janssen (Fentatienyl) for neurolept analgesia (with intubation) of 34 persons who had ophthalmic surgery on account of detachment of the retina. The effects of the drug on the size of the pupils, blood pressure, heart rate and respiration were observed; also the duration of analgesia and the incidence of nausea and vomiting. There was a very slight negative effect on the size of the pupil, similar to that seen with halothane; systolic blood pressure fell by an average of 20%; the duration of analgesia and the degree of respiratory depression varied considerably. 12 of the 35 patients suffered from marked nausea and vomiting after the operation.
