If you have a burning desire to know the origins of caustic, you're already well on your way to figuring it out. Caustic was formed in Middle English as an adjective describing chemical substances, such as lime and lye, that are capable of destroying or eating away at something. The word is based on the Latin adjective causticus, which itself comes ultimately from the Greek verb kaiein, meaning "to burn." In time, caustic was baked into the English language as an adjective describing people or things (such as wit or remarks) that are bitingly sarcastic. Other kaiein descendants in English include cautery and cauterize, causalgia (a burning pain caused by nerve damage), and encaustic (a kind of paint that is heated after it's applied).

Vlad is truly a magician. I binged all of his videos this past weekend hoping to find a solution. This was the closest but I specifically need it to look like water caustics. I thought Photoshop was an option but it needs to be done over a 360 render so that complicates things a little. The pano editing capability in Photoshop is super limited, especially with layers and blending modes.
At the end of the day, I was able to accomplish it in Photoshop using the warp tool to get the general effect. It would be great to have a projector light type in the future... add it to the list of a million Enscape wishes!

If any person maliciously causes any other person bodily injury by means of any acid, lye or other caustic substance or agent or use of any explosive or fire, he shall be guilty of a felony and shall be punished by confinement in a state correctional facility for a period of not less than five years nor more than thirty years.

This activity is designed to equip healthcare professionals with comprehensive knowledge and practical skills in managing caustic ingestions. Focused on the complexities of the upper digestive tract anatomy and the diverse manifestations of caustic injuries, this program discusses diagnostic strategies, evidence-based guidelines, and optimal treatment modalities. Through case-based discussions and interactive sessions, participants will enhance their competence in promptly assessing, triaging, and treating caustic ingestion cases, ultimately improving patient care and outcomes.
Objectives:
The upper digestive tract is the primary site of tissue damage due to caustic ingestion. This part of the gut runs from the head, neck, mediastinum, and epigastric area. The oral region, pharynx, esophagus, stomach, and duodenum comprise the upper gastrointestinal tract (see Image. Digestive and Respiratory Anatomical Structures Connected to the Esophagus).
The oral region (mouth) is the entryway to the digestive system, composed of the oral cavity, gingivae, teeth, tongue, palate, and palatine tonsil area. Mechanical and some enzymatic food digestion take place in the oral cavity. Nonkeratinized stratified squamous epithelium lines most oral mucosal surfaces. Masticatory areas like the gingivae and hard palate have keratinized or parakeratinized stratified squamous epithelium.[69] Mastication muscles surround the oral region.
The pharynx passes from the cranial base to the C6 vertebra level. This upper gut area is divided into the nasopharynx, oropharynx, and laryngopharynx. The nasopharynx and oropharynx have sensory functions during eating. The oropharynx and laryngopharynx help in the transit of food boluses from the oral cavity to the esophagus.
Head and neck structures surrounding the pharynx include the upper respiratory tract, salivary glands, thyroid and parathyroid glands, vagus nerve and its branches, cervical nerves, carotid arteries and its branches, external and internal jugular veins, deglutition muscles, and lymph nodes. Nonkeratinized stratified squamous epithelium lines the pharyngeal mucosal surfaces.
The esophagus is a long muscular tube where food passes from the mouth and pharynx to the stomach. This part of the gut has cervical, thoracic, and abdominal regions. In the neck, the esophagus lies posterior to the larynx and trachea. The thoracic esophagus runs in the mediastinum anterior to the vertebral column, posterior to the trachea, and to the right of the aorta. The abdominal esophagus begins at the T11 vertebral level, where the muscular tube opens to the stomach.
The esophageal mucosa is lined by nonkeratinized stratified squamous epithelium. The upper third of the esophagus has striated muscles. The lower third has smooth muscles. The middle third has mixed striated and smooth muscles. The esophagus has no serosa, so infections and tumors can quickly spread from this muscular tube to the neighboring regions.
The stomach starts at the esophagogastric junction (EGJ), where the mucosal lining transitions from squamous to simple columnar epithelium. Gastric secretions, characterized by high acidity, serve dual roles as digestive agents and potent defense mechanisms against pathogens due to their antimicrobial properties. The mucus protects the stomach from its secretions.
The duodenum is the proximal part of the small intestine, neutralizing acidic chyme and accomplishing most of the digestive process. Bicarbonate secretions raise the duodenal pH. This part of the upper gastrointestinal tract has microvilli and simple columnar epithelium, as it is specialized for food digestion and absorption.
Caustic ingestions can injure any part of the upper digestive tract. The esophagus is most vulnerable to alkaline damage, while the stomach is most prone to acidic injury. Severe cases can cause overspills or gut perforation that can spread the damage to neighboring structures.
Caustic ingestions are severe causes of morbidity and mortality and can affect all age groups. About 80% of caustic ingestion cases in the United States occur in children. For the best outcomes, critical ingestions require coordination between surgical and medical teams.[1]
Caustic exposure can be accidental or intentional. Accidental exposures are most common in young children, often termed "exploratory ingestions." Accidental caustic ingestion often occurs in small amounts and typically involves household cleaners with low concentrations of chemicals like bleach and ammonia. Meanwhile, intentional exposures often result from self-harm attempts and involve large amounts of highly concentrated caustic chemicals.
Most caustic exposures involve oral ingestion (76%) and occur at home (93%). More than 80% of cases are unintentional. Substances ingested are either highly acidic or highly alkaline, requiring different treatment approaches.[1][2]
The American Association of Poison Control Centers reported that 180,000 caustic exposure incidents were documented in the United States in 2019. Most cases involved pediatric accidental ingestion of household cleaning products. The rest were comprised of intentional caustic ingestion cases among adults. The alkaline substance lye is the most frequently reported component in caustic ingestions.
Alkalis are classically associated with liquefactive necrosis. The process involves saponification and subsequent disruption of the lipid-rich cell membranes. Cell lysis releases digestive enzymes, dissolving the surrounding tissues. Strong alkalis can penetrate tissues more deeply than acids and cause more extensive tissue damage.[3]
In contrast, acids are classically associated with coagulative necrosis. Acid-related tissue injury is more superficial due to eschar formation, which limits acid penetration into the underlying tissues.[4] Acid ingestions are associated with "skip lesions," where the esophagus sustains discontinuous areas of damage.
However, distinguishing liquefactive from coagulative necrosis is less important in clinical practice. Strong alkalis and acids are equally capable of severe, full-thickness injury to the gastrointestinal tract.[5]
The titrable acid or alkali reserve (TAR) predicts tissue damage potential more accurately than pH. TAR is estimated by the amount of acid or alkali required to bring a substance's pH to 8.00. The higher the TAR, the more corrosive the agent. Still, pH is more often used in practice than TAR, as pH is more readily available and can approximate TAR in many cases. However, substances like zinc chloride and phenol require TAR values for predicting the potential for tissue damage, as these chemicals have near-physiologic pH but very high TAR.[6]
Other factors that will influence the extent and severity of damage include the physical state of the caustic substance (solid, liquid, or gel), tissue contact time, and quantity and concentration of the offending agent.[7]
