Summary
Calamine lotion on screening mammograms can mimic breast calcifications, potentially leading to misdiagnosis. Early breast cancer detection relies on accurate identification of microcalcifications.
Area of Science:
- Radiology
- Medical Imaging
- Oncology
Background:
- Early detection of breast cancer is crucial for effective treatment.
- Microcalcifications on mammograms are key indicators of potential malignancy.
Observation:
- A screening mammogram revealed suspicious findings that resembled intramammary calcifications.
- The patient had applied calamine lotion prior to the mammogram.
Findings:
- The observed "calcifications" were determined to be a manifestation of calamine lotion.
- Calamine lotion can create artifacts that mimic true microcalcifications on mammography.
Implications:
- Radiologists must be aware of external agents like calamine lotion that can cause false positives.
- Proper patient preparation and history taking are essential to avoid misinterpreting artifacts as pathology.

00:51Synthesis and Functions of Calcitonin
Calcitonin, a vital polypeptide hormone, regulates calcium levels within body fluids. It is released by the parafollicular cells, also known as C cells, situated in the follicular epithelium of the thyroid gland. Calcitonin responds to fluctuations in blood calcium levels and the influence of gastrointestinal hormones like gastrin and cholecystokinin.
The exact mechanisms by which calcitonin operates in calcium homeostasis remain elusive, but its significance is evident in several vital...

01:16Calmodulin-dependent Signaling
Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...
