Antibiogram and molecular characterization of extended-spectrum β-lactamase-producing pathogens implicated in chronic suppurative otitis media.

Introduction: beta-lactamase-producing bacteria, especially extended-spectrum beta-lactamase (ESBL) producers have strong clinical relevance and have been implicated in chronic suppurative otitis media (CSOM) treatment failures. This study aimed to determine the frequency, antibiogram, and molecular characteristics of ESBL-producing gram-negative bacterial (GNB) pathogens isolated from patients with CSOM.

Methods: three hundred (300) ear swab samples collected from patients with active CSOM were analysed using standard microbiological techniques.

Chronic Myeloid Leukaemia with Sudden Bilateral Deafness and Leg Ulcer Associated with Hydroxyurea Therapy.

Deafness occurs rarely in patients with chronic myeloid leukaemia. Hydroxyurea-induced leg ulcer has been found in patients on long-term hydroxyurea therapy. We present a 53 year old man who developed spontaneous bilateral deafness shortly after he was diagnosed with chronic myeloid leukaemia and subsequently developed hydroxyurea induced leg ulcer in the course of treatment.
