RESUMEN
Congenital isolated 'H-type' tracheoesophageal fistula (TOF) is a rare disorder which is difficult to diagnose. Clinical presentation is characterised by a triad consisting of paroxysmal coughing and cyanosis during feeds; recurrent chest infections and failure to thrive; and abdominal distention secondary to gaseous loading of the bowel. It is often difficult to diagnose 'H-type' TOF because the continuity of the oesophagus is not interrupted. The diagnosis is often missed or delayed, leading to complications such as chronic lung disease and failure to thrive.
RESUMEN
Wheezing in infants and under-five children may present a diagnostic problem as there are various aetiologies for this symptom. Diagnosis of asthma is often made as it is one of the causes of wheezing in children. It is however important to have taken a complete history, including allergy and appropriate diagnostic investigations. If the child's symptoms do not improve despite appropriate therapy, a different diagnosis must be pursued. We report the case of a child who presented to us with wheezing and who did not respond to therapy.
