Damage in this location can result in sloughing of the damaged tissue and swelling both of which can cause obstruction of the respiratory tract, ulceration, increased secretions, and redness (erythema).Systemic toxicity can occur from inhalation of chemical compounds produced as byproducts of combustion in a fire. Carbon monoxide poisoning is the most common systemic toxicity after smoke inhalation and can cause organ failure from lack of oxygen (often heart attack). Carbon monoxide is a common byproduct of combusting substances in fires and is colorless and odorless. It has a much higher binding affinity for hemoglobin compared to oxygen and thus can block oxygen from binding to hemoglobin causing hypoxia. Additionally, carbon monoxide decreases the ability of oxygen to dissociate from hemoglobin to diffuse into tissues thus causing hypoxia. Treatment
First responders often take the victim away from the fire and smoke, give 100% oxygen at high flow through a face mask (non-rebreather if available), assess level of consciousness, and check the victim for burns and/or injuries to the body for initial care. Upper respiratory tract injury due to heat exposure often results in swelling. Intubation should be considered early given that the swelling can have a slow, delayed onset but once present, will make intubation very difficult.Lower respiratory tract injury due to exposure to noxious fumes often consists of supportive measures such as intubation and ventilator support if indicated, suctioning of the airways (pulmonary hygiene), and other supportive measures.
Triangular alopecia  is hair loss that may be congenital but usually appears in childhood as a focal patch of loss that may be complete or leaving fine vellus hairs behind. : 643  Affected individuals are typically entirely healthy. Hair restoration surgery using follicular unit transplantation has been a successful treatment modality for TTA

Presentation
Association with Other Conditions
TTA has been associated with several disorders, such as Phakomatosis pigmentovascularis. And a rare syndrome Setleis syndrome. It is inherited by the autosomal dominant trait and is characterized by cutis aplasia or atrophic skin at the temples, which is said to resemble forceps marks. There may also be a coarse facial appearance, anomalies of the eyelashes and eyebrows, and periorbital puffiness. Frequency
The suggested frequency for this condition in the general population is around 0.11%. The hair loss is non-progressive and does not expand beyond these areas. It is a non-inflammatory, non-scarring form of hair loss easily confused with alopecia areata. In one report, the condition was incorrectly believed by the parents to be induced by doctors inserting intravenous cannulas into scalp vessels during the neonatal period. The condition is permanent and the affected skin does not change later in life.Of the 53 reported cases of TTA, more than half (55.8%) were detected in childhood between the ages of 2 and 9 years, while 36.5% were detected at birth and only 3.8% (only two cases) in adulthood.
