Summary
Large vallecular masses are rare and can originate from various sites. Imaging is key, but some masses present diagnostic challenges, requiring careful differential diagnosis.
Area of Science:
- Otolaryngology
- Head and Neck Surgery
- Radiology
Background:
- Vallecular masses are uncommon, encompassing a range of rare pathologies.
- These masses can be intrinsic to the vallecula or extensions from adjacent structures like the tongue base or supraglottis.
Observation:
- Literature review indicates a scarcity of documented vallecular mass presentations.
- Imaging typically aids characterization, but indeterminate appearances can occur.
Findings:
- This series details five cases, including two rare presentations: a low-grade cribriform adenocarcinoma of the tongue base and a vallecular lipoma.
- Three cases highlight differential diagnoses, including benign vallecular cysts and malignant masses from neighboring sites (tongue base, supraglottic larynx) with vallecular components.
Implications:
- Accurate diagnosis of vallecular masses is crucial for appropriate management.
- Recognizing rare presentations and potential for extension from adjacent sites improves diagnostic accuracy.
- Advanced imaging interpretation is vital for differentiating benign from malignant vallecular lesions.

Following assessment, a nursing diagnosis is the next step in the nursing process. It begins after the nurse has collected and recorded the patient data. The purpose of diagnosing is to identify how the client responds to actual or potential health processes, identify factors that bestow or that cause health problems, the etiologies, and identify resources or strengths the individual, group, or community can draw on to prevent or resolve problems.

01:52Atomic Mass
70.4K
Atoms — and the protons, neutrons, and electrons that compose them — are extremely small. For example, a carbon atom weighs less than 2 × 10−23 g. When describing the properties of tiny objects such as atoms, we use appropriately small units of measure, such as the atomic mass unit (amu). The amu was originally defined based on hydrogen, the lightest element, then later in terms of oxygen. Since 1961, it has been defined with regard to the most abundant isotope of carbon, atoms of which...

The identity of a substance is defined not only by the types of atoms or ions it contains but by the quantity of each type of atom or ion. For example, water, H2O, and hydrogen peroxide, H2O2, are alike in that their respective molecules are composed of hydrogen and oxygen atoms. However, because a hydrogen peroxide molecule contains two oxygen atoms, as opposed to the water molecule, which has only one, the two substances exhibit very different properties.

01:26Formulating and Validating Nursing Diagnosis I
3.9K
A nursing diagnosis is written when the nurse recognizes a cluster of essential patient data indicating health problems treated with independent nursing interventions. The standardized terminologies of a nursing diagnosis help nurses identify and treat patients' problems. Every electronic health record that uses nursing diagnosis must employ standard diagnostic terminology. Developing an efficient, individualized care plan begins with accurate nursing diagnoses.

01:10Documentation of Nursing Diagnosis
1.8K
The nurse documents nursing diagnoses and enters them into the patient record. The identified patient's nursing diagnosis is either written out with a plan of care or entered into the electronic health record.
In some settings, data-driven computerized decision support systems are in place, allowing for more accurate nursing diagnoses. The database within one of these systems includes diagnostic labels defining characteristics, activities, and indicators for nursing. A nurse enters...

1.9K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
