Explanation

Craniopharyngioma is a type of brain tumor that occurs near the pituitary gland. It is different from other brain tumors such as Astrocytoma, Meningioma, and Pituitary Adenoma.

Submit
6. What medical condition is associated with the term 'Craniopharyngioma'?

Explanation

Craniopharyngioma is a type of brain tumor that occurs near the pituitary gland. Meningioma, Glioblastoma, and Pituitary adenoma are different types of brain tumors with distinct characteristics.

Submit
7. What type of tumors of the pituitary gland constitute about 5-10% of intracranial tumors?

Explanation

Pituitary adenoma is the most common type of pituitary tumor, accounting for the majority of cases. Sellar tumors refer to tumors located in the sella turcica, while suprasellar tumors are located directly above the sella turcica.

Submit
8. Eosinophilic cells (tumors) produce excess amounts of......

Explanation

Eosinophilic cells (tumors) overproduce certain hormones causing specific symptoms and conditions. The correct answer details the hormonal excess of PRL and GH, leading to specific manifestations. The incorrect answers suggest different hormones and their associated outcomes to mislead test-takers towards incorrect choices.

Submit
9. Basophilic cells (tumors) produce excess amounts of which hormones leading to Cushing's disease?

Explanation

Basophilic cells are part of the pituitary gland and when they produce excess amounts of TSH, Gonadotrophins, and ACTH, it can lead to Cushing's disease.

Submit
10. Chromophobe cells (tumors) produce excess amounts of what?

Explanation

Chromophobe cells are a type of tumor cells that are non-functioning and do not produce any substances or hormones. Unlike other types of tumors, they do not have a specific function or excessive production of any substance.

Submit
11. Sellar/suprasellar tumors- pituitary adenoma, HYPOSECRETION is also called:

Explanation

Panhypopituitarism is the correct term used to describe the condition of reduced secretion of all hormones normally produced by the pituitary gland. The incorrect answers provided are closely related terms but do not specifically refer to the complete underproduction of pituitary hormones as seen in panhypopituitarism.

Submit
12. What occurs when more than 80% of the pituitary is destroyed?

Explanation

panhypopituitarism is the condition in which the pituitary gland is largely or completely dysfunctional, resulting in a deficiency of many or all of the pituitary hormones.

Submit
13. Pituitary apoplexy is caused by ______, leading to severe headache, visual failure, altered consciousness, death.

Explanation

Pituitary apoplexy is a condition where there is sudden bleeding into the pituitary gland or a tumor in the pituitary gland. This bleeding can lead to severe symptoms such as headache, visual disturbances, altered consciousness, and in severe cases, death.

Submit
14. What is a common treatment for PITUITARY APOPLEXY?

Explanation

PITUITARY APOPLEXY is a serious condition that requires immediate treatment. While antibiotics, chemotherapy, and physical therapy may be used for other conditions, the standard treatment for PITUITARY APOPLEXY involves glucocorticoid treatment followed by surgery to address the underlying issues effectively.

Submit
15. What are two operative approaches to reach the pituitary gland?

Explanation

The correct operative approaches to reach the pituitary gland are trans-sphenoidal and trans-frontal. These approaches involve accessing the pituitary gland through either the sphenoid sinus or the frontal sinus, respectively, to treat pituitary disorders.

Submit
16. What condition occurs after a childbirth where there was severe uterine hemorrhage, resulting in severe blood loss and pituitary tissue death?

Explanation

Sheehan's Syndrome is a rare condition that occurs due to severe blood loss during childbirth, leading to pituitary tissue death. Eclampsia is a condition characterized by seizures in pregnant women. Postpartum hemorrhage is excessive bleeding following childbirth. Gestational diabetes is a form of diabetes that occurs during pregnancy.

Submit
17. Sheehan's Syndrome causes hypo or hyper pituitarism?

Explanation

Sheehan's Syndrome, also known as postpartum hypopituitarism, is a condition characterized by pituitary gland dysfunction leading to reduced hormone production.

Submit
18. A lady with inability to breastfeed, fatigue, hypothyroidism, low blood pressure, loss of pubic hair, and amenorrhea after childbirth likely has what condition?

Explanation

Sheehan's syndrome is the correct answer because it presents with hypopituitarism following severe postpartum hemorrhage leading to destruction of the pituitary gland. This results in the symptoms described such as inability to breastfeed, fatigue, hypothyroidism, low blood pressure, loss of pubic hair, and amenorrhea. Postpartum depression, menopause, and polycystic ovary syndrome do not fully encompass all of the symptoms and underlying cause experienced by the individual in the question.

Submit
19. What is the only way to treat Sheehan's syndrome?

Explanation

Sheehan's syndrome is a condition involving pituitary gland dysfunction due to severe postpartum bleeding. The appropriate treatment involves lifelong hormone replacement therapy to maintain hormonal balance.

Submit
20. What syndrome occurs after pituitary trauma?

Explanation

Simmonds syndrome, also known as hypopituitarism, is a condition that occurs after pituitary trauma. It is characterized by the deficiency of one or more pituitary hormones. The incorrect answers are other endocrine disorders that are not specifically associated with pituitary trauma.

Submit
21. What form of hypopituitarism is characterized by deficiencies in all pituitary secretions?

Explanation

Simmonds syndrome, also known as panhypopituitarism, involves deficiencies in all pituitary hormones, leading to a wide array of symptoms related to hormone imbalances.

Submit
22. What medication is used to treat Diabetes Insipidus?

Explanation

Diabetes Insipidus is treated with Vasopressin, which acts on V2 receptors in the kidneys to increase water reabsorption.

Submit
23. Central DI is caused by _____.

Explanation

Central diabetes insipidus (DI) is caused by a lack of ADH, also known as antidiuretic hormone. ADH is responsible for regulating the amount of water excreted by the kidneys. When there is a deficiency of ADH, it leads to excessive urination and extreme thirst, characteristic of DI. Excess ADH secretion, damage to the hypothalamus, and kidney malfunction are not the causes of central DI.

Submit
24. What is the cause of Nephrogenic DI?

Explanation

Nephrogenic DI is caused by the kidneys' inability to respond to ADH, rather than issues with ADH production or release from other glands.

Submit
25. Which type of DI is more common: Central DI or nephrogenic DI?

Explanation

Central Diabetes Insipidus (DI) is more common than nephrogenic DI because it is caused by a deficiency of vasopressin, whereas nephrogenic DI is caused by the kidneys' inability to respond to vasopressin.

Submit
26. What is the etiology of Central DI?

Explanation

Central DI is caused by damage to the hypothalamus or posterior pituitary gland, typically due to surgery, infection, a tumor, or an autoimmune condition. Increased water intake, dehydration, and genetics are not causes of Central DI.

Submit
27. What are some potential etiologies for Nephrogenic DI?

Explanation

Nephrogenic DI can arise from various causes such as kidney disease, drug side effects, electrolyte imbalances, and congenital defects. Bacterial infection, vitamin deficiency, and genetic mutations are not typically associated with Nephrogenic DI.

Submit
28. Which conditions are associated with symptoms of hypernatremia, polyuria, polydipsia, and nocturia?

Explanation

The correct answer includes Central Diabetes Insipidus (DI) and Nephrogenic DI, which are characterized by the given symptoms. Cushing syndrome, Addison's disease, and Grave's disease typically present with different sets of symptoms not matching those listed in the question.

Submit
29. What is the medical term for increased blood sodium content?

Explanation

Hypernatremia is the medical term for increased blood sodium content, while hypokalemia refers to low potassium levels, hyponatremia is low sodium levels, and hyperkalemia is high potassium levels.
