PhysiologyThe normal plasma concentration of glucose that does not lead to its excretion in the urine is approximately 100 mg/100 ml, below which glucose is typically reabsorbed completely.

Oral SurgeryThe reddish patch of median rhomboid glossitis lacks filiform papillae, which are the most numerous papillae covering the anterior two-thirds of the tongue's dorsal surface. These papillae are highly keratinized and are responsible for the tongue's normal white-pink appearance. The absence of these keratinized papillae makes the affected area appear redder and smoother, standing out distinctly from the surrounding normal tongue tissue.

Oral PathologyMigraine is basically vascular in origin, involving vasodilation and inflammation of cranial blood vessels, particularly the trigeminal vascular system. The pathophysiology involves changes in cerebral blood flow and release of vasoactive substances. MPDS is muscular, glossopharyngeal neuralgia is neurologic, and glossodynia is often idiopathic or related to local factors rather than vascular.

PedodonticsA diastema, or space between teeth, can be a normal finding in children, especially during the mixed dentition phase. The presence of a 2 mm diastema between the maxillary central incisors in a 7-year-old is often due to the normal eruption pattern of these teeth, as they may not yet be fully aligned or spaced appropriately.

Pathology
Sarcoidosis is a systemic granulomatous disorder of unknown etiology that can
affect any organ in the body. It is characterized by the formation of non-caseating
granulomas, which are clumps of inflammatory cells that cluster together in
response to an unidentified antigen. The lungs and lymph nodes are most commonly
involved. Here's a detailed explanation for each of the options:
1. Dry cough: This is a common symptom of pulmonary sarcoidosis. The cough is
usually persistent and non-productive, meaning it does not bring up mucus or
phlegm. The presence of a dry cough is not contradicted in the statement "All
are true regarding Sarcoidosis except," so this option is not the correct
answer.
2. Exertional dyspnoea: Shortness of breath on exertion can occur in individuals
with pulmonary sarcoidosis due to the inflammation and granuloma formation in
the lungs. This symptom can be a result of the impaired lung function and
decreased lung capacity caused by the disease. Therefore, this is also a true
statement regarding sarcoidosis.
3. Wheezing: Wheezing is a high-pitched whistling sound that occurs during
breathing, typically heard when airways become narrowed or blocked. It can be a
symptom of pulmonary sarcoidosis, particularly if the disease involves the
bronchi and bronchioles, leading to bronchial obstruction and airflow
limitation. However, it is not the primary symptom and may be less common than
the other respiratory symptoms mentioned.
4. Hemoptysis: While hemoptysis, or coughing up blood, is not a hallmark symptom
of sarcoidosis, it can occur in some cases, particularly when the granulomas are
located in the lungs. It is usually mild and self-limited, but severe cases can
lead to significant bleeding. This is a true statement regarding sarcoidosis, as
it is a possible, although less common, respiratory symptom of the disease.
Since all the options (1, 2, and 4) are true regarding Sarcoidosis

Oral SurgeryMultiple myeloma is a type of cancer that affects plasma cells in the bone marrow. The standard treatment typically involves a combination of therapies, as it is a systemic disease not treatable with localized surgery alone. Chemotherapy, often combined with radiotherapy (especially for localized bone lesions), is the treatment of choice.
