    Resumption of Puberty in Girls and Boys Following Removal of the Histrelin Implant
    (Elsevier, 2014) Fisher, Marisa M.; Lemay, Deborah; Eugster, Erica A.; Pediatrics, School of Medicine
    Objectives: To determine time to menarche in girls and testicular volume increase in boys after removal of a histrelin implant, which causes profound hypothalamic-pituitary-gonadal axis suppression. Study design: Medical records of patients treated with a histrelin implant were reviewed. Seventy-one patients (56 girls) treated with the histrelin implant were identified, of these patients, 37 explanted girls (68% naïve) and 6 explanted boys (83% naïve) were included in the analysis. Time to menarche after explantation in girls and time to testicular volume increase after explantation in boys were determined. Additional variables investigated included indication for and duration of treatment, history of menarche (girls), previous therapy, and age at beginning and end of histrelin treatment. Results: Of the girls, 30 were treated for central precocious puberty (CPP), 26 had menarche at an average of 12.75 months after explantation. Of the 30, 7 were treated for other indications, of whom 6 had reached menarche. In girls with CPP, older age at explantation correlated with sooner menarche (P = .04). All boys achieved spontaneous testicular enlargement within 1 year of explantation. Conclusions: This study documented resumption of puberty after histrelin explantation in treatment naïve and non-naïve boys and girls with and without CPP. Menarche in girls with CPP occurs within a similar timeframe to that observed after other treatment approaches.

    Sequential drain amylase to guide drain removal following pancreatectomy
    (Elsevier, 2018-06) Villafane-Ferriol, N.; Van Buren, G.; Mendez-Reyes, J.E.; McElhany, A.L.; Massarweh, N.N.; Silberfein, E.; Hsu, C.; Tran Cao, H.S.; Schmidt, C.; Zyromski, N.; Dillhoff, M.; Roch, A.; Oliva, E.; Smith, A.C.; Zhang, Q.; Fisher, W.E.; Surgery, School of Medicine
    BACKGROUND: Although used as criterion for early drain removal, postoperative day (POD) 1 drain fluid amylase (DFA) ≤ 5000 U/L has low negative predictive value for clinically relevant postoperative pancreatic fistula (CR-POPF). It was hypothesized that POD3 DFA ≤ 350 could provide further information to guide early drain removal. METHODS: Data from a pancreas surgery consortium database for pancreatoduodenectomy and distal pancreatectomy patients were analyzed retrospectively. Those patients without drains or POD 1 and 3 DFA data were excluded. Patients with POD1 DFA ≤ 5000 were divided into groups based on POD3 DFA: Group A (≤350) and Group B (>350). Operative characteristics and 60-day outcomes were compared using chi-square test. RESULTS: Among 687 patients in the database, all data were available for 380. Fifty-five (14.5%) had a POD1 DFA > 5000. Among 325 with POD1 DFA ≤ 5000, 254 (78.2%) were in Group A and 71 (21.8%) in Group B. Complications (35 (49.3%) vs 87 (34.4%); p = 0.021) and CR-POPF (13 (18.3%) vs 10 (3.9%); p < 0.001) were more frequent in Group B. CONCLUSIONS: In patients with POD1 DFA ≤ 5000, POD3 DFA ≤ 350 may be a practical test to guide safe early drain removal. Further prospective testing may be useful.
