Prevention of Further Absorption of Poison

Prevention of Further Absorption of Poison

In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...

Local Anesthetics: Adverse Effects

Local Anesthetics: Adverse Effects

While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

Cellular Injury IV: Necrosis

Cellular Injury IV: Necrosis

Necrosis is a form of irreversible cell death caused by severe injury such as ischemia, toxins, or trauma. Unlike programmed cell death, it is an uncontrolled, pathological process that typically provokes inflammation in surrounding tissues.Pathophysiologic ChangesNecrosis begins when cells sustain critical damage, leading to swelling of organelles, particularly mitochondria, and rapid ATP depletion. As energy levels decline, membrane ion pumps fail, leading to calcium influx and eventually,...

Necrosis

Necrosis

Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.
One of the advantages of...

Summary

This summary is machine-generated.

Localized skin necrosis at apomorphine injection sites is a rare but serious side effect in Parkinson's disease patients. Biopsy confirmed this finding, suggesting potential immune complex mechanisms.

Background:

Apomorphine, a dopaminergic agonist, treats Parkinson's disease fluctuations.
It's typically administered via subcutaneous injection or continuous infusion.
Localized cutaneous necrosis at injection sites is a potential adverse effect.

Observation:

Two male Parkinson's patients developed necrotic lesions (2-5 mm) at apomorphine injection sites.
Skin biopsies revealed varying degrees of necrosis, inflammation, and vasculitis.
Coagulation studies were normal; one patient used aspirin.

Findings:

This is the first biopsy-proven report of apomorphine-induced localized skin necrosis.
Histopathology indicated potential immune complex mechanisms, including vasculitis.
Necrosis severity varied, with some cases improving upon drug cessation.

Implications:

Apomorphine-induced skin necrosis, though rare, requires clinical awareness.
Potential mechanisms include direct toxicity or immune responses.
Further research is needed to elucidate the exact pathophysiology and management strategies.
