Potassium permanganate (KMnO4) is rarely used for suicidal attempt. Its ingestion can lead to local as well as systemic toxicities due to coagulation necrosis and damage, caused by free radicals of permanganate. We recently managed a case of suicidal ingestion of KMnO4 in a lethal dose. She had significant narrowing of upper airway leading to difficult intubation as well as hepatic dysfunction ...

background: endoscopy of the upper gastrointestinal tract is the most accurate method for the diagnosis of most disease conditions associated with dyspepsia. however, endoscopy involves some discomfort, significant social inconvenience, and cost. attempts to identify those patients most likely to benefit from endoscopy have met with variable success. to evaluate endoscopic findings of the upper...

Vascular anomalies are disorders of abnormal vasculogenesis or lymphogenesis. All types of vascular anomalies may involve the airway, causing varying degrees of upper airway obstruction as well as dysphagia and bleeding. Certain signs and symptoms may implicate airway involvement with a hemangioma or vascular malformation. It is necessary to distinguish a vascular anomaly from other airway lesi...

background : upper endoscopy, as an important diagnostic and occasional therapeutic tool is invasive. sedation of patients during the endoscopy procedure with minimal side effects could raise patient tolerability, allowing for ease and increased effectiveness of this procedure. materials and methods: in this study, 105 patients who were candidates for the upper endoscopy procedure were randomly...

Congenital central hypoventilation syndrome (CCHS) is the failure of the autonomic system to control adequate ventilation while asleep with preserved ventilatory response while awake. We report a case of a patient with CCHS who presented with intrathoracic and extrathoracic airway obstruction after tracheostomy tube decannulation and phrenic nerve pacer placement. Nocturnal polysomnography (NPS...

Drug induced sleep endoscopy is the most important investigation before surgical planning of obstructive sleep apnea patient. It is performed by artificially inducing sleep in a patient and performing nasal endoscopy in order to identify the site of upper airway obstruction. The most appropriate anesthetic agent would be that which induces sleep without any respiratory inhibition. Propofol has ...

We report an unexpected massive left pneumothorax at the end of a digestive upper endoscopy without evidences of perforation or airway over-pressure. The possible air passage through a diaphragmatic failing is discussed.
