Diabetes Insipidus and SIADH Overview

A disorder where the body doesn't produce enough antidiuretic hormone (ADH), leading to excessive urination and thirst.

A hormone that tells the kidneys to conserve water, and concentrating urine.

A type of DI caused by insufficient ADH release from the brain, potentially due to head injury or tumor.

A form of DI where the kidneys don't respond to ADH.

A condition where the body produces too much antidiuretic hormone (ADH), causing an unusual amount of water retention and low sodium levels.

Low sodium levels in the blood, often a symptom of SIADH.

SIADH can result from various conditions such as certain tumors, medications, or injuries affecting the brain or lungs.

DI is relatively infrequent in the U.S., with equal occurrences in males and females.

The frequency of SIADH increases with age and may be hospital-acquired related to stress.

Another name for antidiuretic hormone (ADH).

A condition with a lack of vasopressin, causing dilute urine, high thirst, and hypernatremia.

A condition with excess vasopressin, causing concentrated urine, low thirst, and hyponatremia.

A hormone that regulates water balance in the body.

Urine with a low concentration of dissolved substances.

Urine with a high concentration of dissolved substances.

Excessive urination; increased urine production.

Excessive thirst; an increased urge to drink.

The amount of liquid in the blood plasma.

A life-threatening condition where the thyroid gland produces excessive amounts of thyroid hormones, resulting in a rapid increase in heart rate, fever, and other serious symptoms.

A life-threatening condition caused by severe hypothyroidism, where the body's metabolism slows down drastically, leading to a coma.

A hormone that measures the amount of active thyroid hormone in the blood. Elevated levels indicate hyperthyroidism, while decreased levels suggest hypothyroidism.

A condition where the thyroid gland doesn't produce enough thyroid hormone, leading to slowed metabolism and various symptoms like fatigue, weight gain, and cold intolerance.

A condition where the thyroid gland produces too much thyroid hormone, leading to an accelerated metabolism and symptoms like weight loss, increased heart rate, and anxiety.

A type of hypothyroidism where the problem lies in the pituitary gland or hypothalamus, which controls thyroid hormone production.

A hormone that measures the amount of active T3 in the blood. Elevated levels can indicate hyperthyroidism, especially in cases where T4 levels are normal.

A type of hyperthyroidism where the body has high levels of T3 but normal T4 levels, indicating an overproduction of T3 specifically.

A condition where the thyroid gland is overactive, often characterized by the preferential secretion of T3 over T4.

A condition where the thyroid gland has multiple nodules (lumps) and is overactive, often with increased T3 production.

Medications used to treat seizures, such as phenytoin, carbamazepine, and rifampin.

The process by which the liver breaks down and processes substances in the body, including hormones.

A thyroid nodule that is unlikely to be cancerous, often with a history of goiter or hyperthyroidism.

A thyroid nodule that has a higher chance of being cancerous, often with family history of thyroid cancer, recent growth, hoarseness, or dysphagia.

A thyroid nodule that appears bright on a thyroid scan, indicating increased thyroid hormone production.

A thyroid nodule that appears dark on a thyroid scan, indicating less thyroid hormone production.

A thyroid nodule that consists entirely of fluid, appearing as a clear sac on an ultrasound.

A thyroid nodule that contains both solid tissue and fluid, appearing as a mixed structure on an ultrasound.

Proteins made by the immune system that target the thyroid gland, potentially leading to hyperthyroidism or hypothyroidism.

A condition where the thyroid gland is enlarged with multiple nodules.

Loss of voice due to damage or dysfunction of the vocal cords, potentially caused by a growing thyroid nodule.

A medical test that uses radioactive iodine to evaluate the function and structure of the thyroid gland.

A generalized enlargement of the thyroid gland.

An irregular enlargement of the thyroid gland with nodules (lumps).

Nodules over 1cm on imaging require further evaluation due to a higher risk of malignancy. Smaller nodules may need investigation if suspicious sonographic findings or additional risk factors are present.

Age (60+), childhood head/neck irradiation, total body irradiation for BMT, family history of thyroid cancer.

Recent growth of a nodule, hoarseness, dysphagia (difficulty swallowing), or obstruction should raise suspicion for thyroid cancer.

The thyroid gland produces hormones that regulate metabolism, affecting nearly every body system, including energy usage, heart rate, and body temperature.

Thyroid hormone directly influences the heart, increasing heart rate, contractility, and relaxation of smooth muscle, leading to increased cardiac output.

A hormone produced by the pituitary gland that stimulates the thyroid gland to produce its own hormones.

A hormone that measures the amount of active thyroid hormone in the blood. Elevated levels indicate hyperthyroidism.

A condition of excessive thyroid hormone in the bloodstream, leading to various symptoms like rapid heartbeat, weight loss, and nervousness.

A state where the thyroid gland is functioning normally.

Blood tests used to assess the function of the thyroid gland by measuring levels of thyroid hormones and TSH.

TSH and FT4 have an inverse relationship. When FT4 levels are high, TSH levels are low, and vice versa.

The ability to think rationally, communicate appropriately, learn, grow emotionally, be resilient, have healthy self-esteem, realistic goals and function well within one's role.

Disorders with diagnosable criteria that cause significant dysfunction in mental functioning due to developmental, biological, or physiological disturbances. They are also influenced by cultural context.

The Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, used by mental health professionals to diagnose psychiatric disorders.

These are used to assess the severity of a diagnosed mental disorder, confirm the diagnosis, and track treatment progress.

Mental health is characterized by the ability to think rationally, communicate effectively, learn and grow emotionally, be resilient, have healthy self-esteem, set realistic goals, and function well within one's role.

The medical record is a legal document that accurately reflects the patient's condition, treatment, tests, responses, and any untoward incidents.

The Mental Status Exam (MSE) documentation should include observations on the patient's appearance, behavior, mood, thought processes, and cognitive functions.

When documenting the MSE, use a structured approach, provide verbatim examples, clarify judgments with examples, be specific, avoid global statements, and record your responses to the patient and the interview.

Nonadherence refers to a patient's failure to follow the healthcare provider's instructions, including medication regimens, lifestyle changes, or therapy appointments.

Understanding the patient's perspective on their illness is crucial for effective healthcare. Their explanation can provide valuable insights into their understanding, coping mechanisms, and the impact of their illness on their life.

A comprehensive evaluation used to gather information about a patient's mental health and functioning, including symptoms, medical history, social and cultural factors, and current life circumstances.

A standardized tool used to assess a person's mental state, including their appearance, behavior, mood, thought processes, and cognitive abilities. It helps identify immediate threats and diagnose mental health disorders.

The initial impressions gained by observing a person's physical appearance, mannerisms, hygiene, and overall behavior during a Mental Status Examination.

A part of the MSE that assesses a person's awareness, orientation, memory, and cognitive abilities. It helps determine if someone is aware of their surroundings and can think clearly.

A part of MSE focused on how a person thinks, including their rate of speech, coherence, and organization of thoughts. It helps identify potential problems with logical reasoning and problem-solving.

A part of MSE that focuses on the specific content of a person's thoughts, including delusions, hallucinations, obsessions, and other abnormal thoughts. Understanding the content of thoughts is essential in diagnosing mental disorders.

A part of MSE that assesses a person's emotional state, including their mood, affect, and any specific emotional experiences like anxiety, anger, or hopelessness.

A person's ability to understand their own mental condition, how their symptoms affect their life, and their role in seeking help. It is a crucial factor in treatment planning and success.

Psychiatry views mental health through four lenses: diseases (what the patient has), dimensions (what the patient is like), behaviors (what the patient does), and life story (the patient's experiences).

When diagnosing, first rule out general medical conditions or substance use. Then, consider cultural, developmental, and diversity factors.

Diagnosis involves grouping disorders, discriminating within those groups, assessing impairment and resilience, and resolving uncertainty.

A Mental Status Exam (MSE) assesses a person's current mental state, including their appearance, behavior, mood, thinking, and cognitive functions. It helps identify immediate threats and diagnose disorders.

A MSE covers general observations, sensorium and intelligence, thought processes, thought content, emotional state, and insight.

Sensorium refers to a person's awareness and orientation. Assessing this involves checking their level of consciousness, orientation to time and place, and memory.

Thought content examines the specific ideas and beliefs a person has. It looks for abnormal thoughts like delusions, hallucinations, obsessions, or compulsions.

Thought processes examine how a person thinks, including their rate of speech, coherence, and organization of ideas. It helps identify issues with logical reasoning.

Emotional state assesses a person's mood, affect, and any specific emotional experiences like anxiety, anger, or hopelessness.

Insight is assessed by evaluating a person's understanding of their mental state, their symptoms' impact on their life, and their role in seeking help.

A standardized assessment of a person's mental state, including their appearance, behavior, mood, thought processes, and cognitive abilities.

Recording the observations and findings from a Mental Status Exam, which should be clear, structured, and specific, using verbatim examples when possible.

The medical record is a legal document that accurately reflects a patient's condition, treatments, tests, responses, and any incidents.

When a patient doesn't follow their healthcare provider's instructions, like medication regimens, lifestyle changes, or therapy appointments.

Understanding the patient's perspective on their problem is crucial for effective healthcare. Their explanation can offer insights into their understanding and coping.
