          Abstract

          La dyspnée laryngée représente une urgence extrême en otorhinolaryngologies. Elle répond à des étiologies multiples et reste souvent graves. La dyspnée laryngée causée par une sangsue est exceptionnellement décrite dans la littérature surtout chez l’adulte. Nous rapportons une observation particulière d’infestation de l’arbre respiratoire par une sangsue ayant entraîné une dyspnée laryngée.

          Translated abstract

          Foreign bodies in the upper respiratory tract are one of the most difficult otolaryngological emergencies; leeches are a very rare foreign bodies in the world. We report the case of a 70-year-old man with no past medical history presenting with laryngeal dyspnea associated with low abundant paroxysmal hemoptysis. The patient underwent nasofibroscopy showing the presence of a living and mobile organism at the subglottic level evoking a leech. Extraction was carried out under local anesthesia using laryngoscope and Magill forceps. The presence of a leech as a foreign body in the upper respiratory tract should be suspected in patients with a recent history of consumption of non-potable water.

          The role of the leech in medical therapeutics.

          Leeching is considered by many to be a discredited medical relic of the past. This view is not justified, since leeches still play an important part in modern medicine, as in microsurgery and in the treatment of patients with post-phlebitic syndrome. Hirudin, the potent thrombin inhibitor of leech saliva, has been cloned and is used in the treatment of cardiological and hematological disorders. In our search for other antihemostatic factors in Hirudo medicinalis saliva, we found inhibitors of platelet aggregation induced by thrombin, collagen, adenosine 5'-diphosphate, epinephrine, platelet-activating factor and arachidonic acid. We purified apyrase (adenosine 5'-triphosphate diphosphohydrolase), which is a non-specific inhibitor of platelet aggregation by virtue of its action on adenosine 5'-diphosphate. We isolated and characterized the platelet-activating factor antagonist and also identified and recovered an inhibitor of coagulation factor Xa from leech saliva. This report summarizes our findings and those of other investigators, as well as the experience of one of us (A.E.) in leech therapy.

            A nasopharyngeal mass: leech in the nasopharynx.

            This paper presents a case with a 4-month history of nasal obstruction and intermittent epistaxis. The cause was found to be a leech in the nasopharynx by means of endoscopic examination. Leech endoparasitism, although rare, may cause serious, even lethal, complications. A high index of suspicion of leech infestation must be entertained when faced with nasal obstruction and intermittent epistaxis in children, and should be investigated surgically as with all other foreign bodies.

              Aquatic leech infestation: a rare cause of severe anaemia in an adolescent Tanzanian girl.

              We report on a 15-year-old girl who presented with a history of chest pain, coughing, intermittent haemoptysis, fever, pallor and vomiting to a rural hospital in Tanzania. She was severely anaemic with signs of cardiorespiratory distress. Haemoglobin was 4.8 g/dl; the chest X-ray film was normal. She required one unit of blood. After 3 days, she vomited up a small parasite which proved to be an aquatic leech. Oesophagogastroscopy, then performed, revealed four small mucosal lesions in the pharynx and upper oesophagus. No other leeches were seen. Further oesophagogastroscopy 4 days later showed a normal mucosa. The girl was discharged on iron and folic acid supplements. A small lake near her village was identified as the likely source of her infestation. The family had used the water for drinking without any precautions-Terrestrial leeches can cause profound, life-threatening anaemia, but even more so do aquatic leeches. This type is acquired while bathing or drinking unfiltered water. They attach themselves to mucous membranes, having been described in sites like conjunctiva, nose, pharynx/larynx, trachea/bronchi, oesophagus, vagina, and rectum. Especially in the airways, they can cause even fatal bleeding or obstruction. Treatment consists of removal of the leech. In developing countries, even unusual causes like leech infestation have to be considered in the differential diagnosis of severe anaemia in children.
