Acromegaly
Acromegalyzakariy al-nuaimi Acromegaly is a hormonal disorder that develops when your pituitary gland produces too much growth hormone during adulthood
Disorders of adrenal gland
Disorders of adrenal glandGAMANDEEP The two adrenal glands produce three main types of hormones: glucocorticoids, mineralocorticoids, and androgens. Cushing's syndrome occurs when there is excessive production of adrenal cortex hormones due to tumors, medications, or other causes. It leads to increased blood glucose, high blood pressure, weight gain, and other issues. Addison's disease is the opposite condition caused by inadequate adrenal hormone production due to issues like autoimmune destruction. It results in low blood pressure, low blood glucose, increased skin pigmentation, and other problems. Both conditions require lifelong hormone replacement therapy and management of complications like infections and adrenal crises.
Acromegaly.ppt
Acromegaly.pptMedical Knowledge Acromegaly is a chronic disease caused by excessive growth hormone production, usually from a pituitary tumor, leading to enlarged hands, feet, and lower face. Gigantism is similar but occurs in childhood, resulting in excessive growth and height over 7 feet. Panhypopituitarism is decreased secretion of pituitary hormones, causing dwarfism in children and Simmond's disease in adults, characterized by multiple hormone deficiencies.
Cushing Syndrome
Cushing SyndromeDr. Binu Babu Nursing Lectures Incredibly Easy Cushing syndrome is characterized by excess cortisol secretion caused by too much ACTH from the pituitary gland or excess cortisol from adrenal tumors. It presents with weight gain, thin extremities, moon face, skin changes, and metabolic complications. Diagnosis involves urine and blood tests to measure cortisol levels. Treatment depends on the underlying cause but may include surgery to remove tumors, radiation therapy, or medications to reduce cortisol levels. Nursing care focuses on preventing infections, injuries, skin breakdown and improving nutrition, fluid balance and body image.
Acromegaly & gigantism
Acromegaly & gigantismSeLipar PuTus Acromegaly and gigantism are chronic metabolic disorders caused by excessive growth hormone levels. Acromegaly occurs in adulthood after bone growth plates have closed, causing tissue enlargement. Gigantism occurs in childhood before plate closure, resulting in abnormally large growth. Both are usually due to noncancerous pituitary tumors that overproduce growth hormone, leading to increased insulin-like growth factor levels and symptoms like enlarged hands, feet and head. Diagnosis involves blood tests and imaging to identify the source of excess growth hormone. Treatment focuses on surgery, radiation or medications to reduce hormone levels and stop further growth.
Parathyroid disorders
Parathyroid disordersGAMANDEEP The document discusses the parathyroid glands, which regulate calcium and phosphate levels and produce parathyroid hormone (PTH). It describes hyperparathyroidism and hypoparathyroidism, conditions caused by excessive or deficient PTH respectively, and their symptoms, causes, assessments, and treatment including diet modifications and medications. Surgical removal of the parathyroid glands may be required to treat hyperparathyroidism.
Cushings syndrome
Cushings syndromeRatheesh R This document provides information about Cushing's disease/syndrome, which is a hormonal disorder caused by prolonged high levels of the cortisol hormone. It is usually due to a benign tumor in the pituitary gland that causes excessive production of ACTH, stimulating the adrenal glands to overproduce cortisol. Symptoms include weight gain, muscle wasting, high blood pressure, and mental disturbances. The condition is diagnosed through tests measuring cortisol and ACTH levels and imaging to identify tumors. Treatment involves medication to suppress cortisol production, adrenalectomy to remove the glands, or pituitary surgery to remove tumors.

Acromegaly-pathogenesis
Acromegaly-pathogenesisNuwani Kodi Growth hormone is secreted by the anterior pituitary and is essential for linear growth. It acts through somatomedins like Somatomedin-C, which are produced in the liver and bone. The hypothalamus stimulates growth hormone secretion through growth hormone releasing hormone and inhibits it through somatostatin. Other neurotransmitters like dopamine can also influence growth hormone levels. Acromegaly results from excess growth hormone secretion in adults after growth plate fusion and is usually caused by a pituitary adenoma. These adenomas can be microadenomas under 10mm or macroadenomas over 10mm, which may produce hormone excess and mass effects. Acromegaly causes characteristic physical changes and symptoms.

MyxoedemaDr. Armaan Singh Myxoedema coma is a life-threatening manifestation of severe, untreated hypothyroidism. It occurs when the body's compensatory mechanisms for coping with low thyroid hormone levels are overwhelmed, such as by infection, drugs, or other illness. Left untreated, it can affect multiple organ systems as the adaptations that help maintain homeostasis start to fail. Symptoms include deterioration of mental status, reduced brain function, hypothermia, slowed metabolism and reflexes, bradycardia, edema, and respiratory issues. Prompt diagnosis and treatment are needed to avoid permanent brain damage or death.

Dwarfism
Dwarfismlaurenc__12345 There are over 300 causes of dwarfism, with the most common being a spontaneous mutation of the FGFR3 gene. The two main types of skeletal dysplasia that cause dwarfism are short trunk with average limbs, and average trunk with shorter limbs and larger head. People with dwarfism can lead normal, healthy lives through treatments like surgery, nutrition plans, physical therapy and hormone injections depending on the type of dwarfism. The likelihood of having a child with dwarfism depends on factors like the parents' height and whether one or both parents carry a dwarfism gene.
acromegaly,gigantism and dwarfism
acromegaly,gigantism and dwarfismmandira dahal This document discusses several types of dwarfism, including pituitary dwarfism, achondroplasia, and dystrophic dysplasia. Achondroplasia is the most common type of dwarfism, accounting for half of all cases, and is characterized by short limbs and a slightly enlarged head. Dystrophic dysplasia was once thought to be a form of achondroplasia, and individuals with this type can experience respiratory and orthopedic problems requiring surgery. Dwarfism is typically diagnosed in childhood based on visible symptoms, and genetic testing and diagnostic imaging can aid in determining the specific type.

Dr. Jaymee Shell’s Perspective on COVID-19
Dr. Jaymee Shell’s Perspective on COVID-19Jaymee Shell Dr. Jaymee Shell views the COVID-19 pandemic as both a crisis that exposed weaknesses and an opportunity to build stronger systems. She emphasizes that the pandemic revealed critical healthcare inequities while demonstrating the power of collaboration and adaptability.
Shell highlights that organizations with gender-diverse executive teams are 25% more likely to experience above-average profitability, positioning diversity as a business necessity rather than just a moral imperative. She notes that the pandemic disproportionately affected women of color, with one in three women considering leaving or downshifting their careers.
To combat inequality, Shell recommends implementing flexible work policies, establishing clear metrics for diversity in leadership, creating structured virtual collaboration spaces, and developing comprehensive wellness programs. For healthcare providers specifically, she advocates for multilingual communication systems, mobile health units, telehealth services with alternatives for those lacking internet access, and cultural competency training.
Shell emphasizes the importance of mental health support through culturally appropriate resources, employee assistance programs, and regular check-ins. She calls for diverse leadership teams that reflect the communities they serve and community-centered care models that address social determinants of health.
In her words: "The COVID-19 pandemic didn't create healthcare inequalities – it illuminated them." She urges building systems that reach every community and provide dignified care to all.
