An Unusual Case of Anterior Abdominal wall Dialysate Leak Diagnosed with Tc99m-Sulfur Colloid Single-Photon Emission Computed Tomography/Computed Tomography Peritoneal Scintigraphy.

Peritoneal dialysis (PD) was commonly used renal replacement therapy for treating end-stage renal failure patients leading to various infectious and mechanical complications. We present a case of a 50-year-old female patient who presented with reduced dialysate return and abdominal wall edema following continuous ambulatory PD. Peritoneal scintigraphy done on suspicion of dialysate leak shows tracer accumulation in the anterior abdominal wall below the insertion of the peritoneal catheter.

Synthesis and Biological Evaluation of 8-Quinolinamines and Their Amino Acid Conjugates as Broad-Spectrum Anti-infectives.

In the search of therapeutic agents for emerging drug-resistant parasites, the synthesis of newer classes of 8-quinolinamines has emerged as a successful chemotherapeutic approach. We report synthesis of 8-quinolinamines bearing 5-alkoxy, 4-methyl, and 2-tert-butyl groups in the quinoline framework and their amino acid conjugates as broad-spectrum anti-infectives. 8-Quinolinamines exhibited potent in vitro antimalarial activity [IC50 = 20-4760 ng/mL (drug-sensitive Plasmodium falciparum D6 strain) and IC50 = 22-4760 ng/mL (drug-resistant P. falciparum W2 strain)]. The most promising analogues have cured all animals at 25 mg/kg/day against drug-sensitive Plasmodium berghei and at 50 mg/kg/day against multidrug-resistant Plasmodium yoelii nigeriensis infections in Swiss mice. The in vitro antileishmanial activities (IC50 = 0.84-5.0 µg/mL and IC90 = 1.95-7.0 µg/mL) comparable to standard drug pentamidine were exhibited by several of the synthesized 8-quinolinamines. At the same time, very promising antifungal activities (Candida albicans-IC50 = 4.93-19.38 µg/mL; Candida glabrata-IC50 = 3.96-19.22 µg/mL; Candida krusei-IC50 = 2.89-18.95 µg/mL; Cryptococcus neoformans-IC50 = 0.67-18.64 µg/mL; and Aspergillus fumigatus-IC50 = 6.0-19.32 µg/mL) and antibacterial activities (Staphylococcus aureus-IC50 = 1.33-18.9 µg/mL; methicillin-resistant S. aureus-IC50 = 1.38-15.34 µg/mL; and Mycobacterium intracellulare-IC50 = 3.12-20 µg/mL) were also observed. None of the 8-quinolinamines exhibited cytotoxicity and therefore are a promising structural class of compounds as antiparasitic and antimicrobials.
