Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Epistaxis01:30

Epistaxis

Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...
Leishmaniasis01:30

Leishmaniasis

Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
Respiratory Syncytial Virus Disease01:29

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
Tonsillitis I: Introduction01:30

Tonsillitis I: Introduction

Tonsillitis is inflammation of the tonsils, which are two lymphoid tissue masses at the back of the throat. This condition can cause discomfort and irritation in the throat.
Etiology
Three primary contributing factors have been identified.
Nose and Nasal Cavity01:24

Nose and Nasal Cavity

The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Summary

Epistaxis in children is rarely caused by leech infestation, a condition easily missed. Early diagnosis and removal of nasal leeches are crucial for treating this rare cause of recurrent nosebleeds.

Area of Science:

  • Otolaryngology
  • Pediatric Medicine
  • Parasitology

Background:

  • Epistaxis (nosebleeds) in children typically results from local factors like dryness, trauma, or inflammation.
  • Nasal hirudiniasis, or leech infestation in the nasal cavity, is an uncommon but significant cause of epistaxis.
  • This condition is often overlooked, leading to delayed diagnosis and treatment.

Purpose of the Study:

  • To report a case of pediatric epistaxis caused by leech infestation.
  • To review the literature on nasal hirudiniasis in children.
  • To analyze clinical characteristics, diagnosis, and treatment strategies for this rare condition.

Main Methods:

  • Case report of a child presenting with epistaxis.
  • Literature review focusing on epistaxis due to leech infestation in pediatric patients.
  • Diagnostic methods included anterior rhinoscopy and endoscopic examination for leech detection.
  • Treatment involved complete leech removal, nasal irrigation, and supportive anti-infective measures.

Main Results:

  • The case highlights recurrent unilateral epistaxis, nasal obstruction, and a sensation of crawling in the nose as key symptoms.
  • A history of exposure to natural water sources was noted in affected children.
  • Diagnosis relies on direct visualization of leeches within the nasal cavity, differentiating it from common epistaxis causes.

Conclusions:

  • Leech infestation should be considered in the differential diagnosis of intractable epistaxis in children, especially in endemic areas or with relevant exposure history.
  • Prompt identification and removal of nasal leeches are essential for effective management.
  • Increased clinical vigilance can prevent misdiagnosis and improve patient outcomes.
