Precipitation Gravimetry

Precipitation Gravimetry

Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...

Drug toxicity: Idiosyncratic Reactions

Drug toxicity: Idiosyncratic Reactions

Idiosyncratic drug reactions represent abnormal chemical responses that vary significantly among individuals, ranging from extreme sensitivity to low doses to insensitivity to high doses. These reactions often occur due to the drug's covalent binding with serum proteins, forming a foreign hapten that triggers an immunotoxicological response. The variability in drug reactions has a strong pharmacogenetic foundation, with genetic differences crucial in how individuals metabolize drugs. For...

Drug Toxicity: Allergic Reactions

Drug Toxicity: Allergic Reactions

Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial exposure to a...

Local Anesthetics: Differential Sensitivity of Nerve Fibers

Local Anesthetics: Differential Sensitivity of Nerve Fibers

Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...

Area of Science:

Dentistry

Allergology

Background:

Common "non-precious" dental alloys include chromium-cobalt, nickel-chromium, and nickel-chromium-beryllium.
These alloys offer high porcelain-to-metal bond strength but have limited flexibility.
Nickel, prevalent in many non-precious alloys, is a frequent cause of metal contact allergies.

Observation:

A patient presented with a sensitivity reaction attributed to the metal component of a ceramo-metal crown.
The reaction was linked to the nickel content within the alloy used for the crown.

Findings:

The case highlights the potential for allergic responses to nickel-containing dental restorations.
Successful management involved identifying and addressing the metal sensitivity.

Implications:

Clinicians should consider potential metal allergies when selecting dental alloys.
Awareness of nickel allergy is crucial for preventing adverse reactions in patients receiving ceramo-metal restorations.
Further research into hypoallergenic dental materials is warranted.
