Vitamin A deficiency can cause xerophthalmia, which is a medical condition where the eye fails to produce tears. It is a leading cause of preventable blindness in children worldwide. The document discusses vitamin A's role in vision and other body processes. Populations most at risk for deficiency include children aged 6 months to 6 years, pregnant and lactating women, and those in developing countries or with malabsorption issues. Signs of xerophthalmia include dryness of the eyes, conjunctival spots, and corneal ulceration or keratomalacia in severe cases. Treatment involves high doses of vitamin A supplementation, while prevention focuses on food fortification, nutrition education, and immunization programs.

micro teaching on communication m.sc nursing.pdfAnurag Sharma
Microteaching is a unique model of practice teaching. It is a viable instrument for the. desired change in the teaching behavior or the behavior potential which, in specified types of real. classroom situations, tends to facilitate the achievement of specified types of objectives.
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

3. Vitamin A - Needed everywhere.
Vitamin A is one of a group of fat soluble vitamins that are essential
for life and health. Three active forms: retinol, retinal and retinoic.
Vitamin A plays a critical role in:
•Vision (A is part of rhodopsin, the visual pigment)
•Epithelial tissues need to protect integrity.
•Growth
•Reproduction
•Pattern formation during embryogenesis
•Bone development
•Brain development
•Immune system function
Deficiency Diseases: Keratinization, xerosis, Xerophthalmia,
Infections, Weak bones, poor teeth.
4.
5. • Vitamin A deficiency is a preventable cause of blindness.
• It is a well-known cause of blindness and is associated with elevated mortality among
infants and children.
• People most at risk are children between six months to six years, pregnant women,
and lactating women.
• One of the main causes of Xerophthalmia is the poor intake of vitamin A, this disease
is also associated with:
Faulty feeding habits
Mal absorption syndromes (cystic fibrosis, Whipple's disease, Crohn's disease,
ulcerative colitis, short bowel syndrome, gastroenteritis, measles)
Pancreatic disease
Chronic liver disease
Weight Loss Surgery
Poverty
Ignorance
and some other conditions among the entire population, but mainly in developing
countries and in young children all over the world in particular.
6. Xerophthalmia
• Xerophthalmia (Greek for dry eyes) is a medical condition in which the eye fails
to produce tears. It may be caused by a deficiency in vitamin A and is sometimes
used to describe that lack, although there may be other causes.
Other causes include:
• Hypothyroidism
• Rheumatoid arthritis
• Sarcoidosis
• Scleroderma
• Sjogren's syndrome
• Systemic lupus erythematosus
• Drugs
– Antihistamines
– Nasal decongestants
– Tricyclic antidepressants
• Conjunctivitis
• Keratoconjunctivitis
• Keratoconjunctivitis sicca
7.
8. • Xerophthalmia caused by a severe vitamin A deficiency is
described by pathologic dryness of the conjunctiva and
cornea. The conjunctiva becomes dry, thick and
wrinkled. If untreated it can lead to corneal ulceration
and ultimately in blindness.
• Xerophthalmia is a term that usually implies a
destructive dryness of the conjunctival epithelium due to
dietary vitamin A deficiency — a rare condition in
developed countries, but still causing much damage in
developing countries. Other forms of dry eye are
associated with aging, poor lid closure, scarring from
previous injury, or autoimmune diseases.
12. Signs of Xerophthalmia
Top left: Bitot's spot
Top right: Cornea with typical dry appearance and ulcer stained green with fluorescein dye;
Bottom right: Corneal scarring;
Bottom left: Deep corneal ulceration progressing towards keratomalacia.
16. Symptoms
• Night Blindness (poor vision at night or in dim light)
• Extreme dryness of the eyes
• Dry, foamy & silver-gray deposits on bulbar conjunctiva
• Wrinkling, progressive cloudiness of corneas.
17.
18. Other factors involved in Xerophthalmia
Protein energy malnutrition (PEM)
Generalized infections (measles, malaria, gastroenteritis)
Exposure ulcers
Herpes simplex
Intestinal parasites
Treatment from traditional healers
20. W.H.O.’s recommended doses
(for treatment of children over 1 year of age)
Immediately on diagnosis 200,000 IU vit.A orally
(Day 1)
The following day 200,000 IU vit.A orally
(Day 2)
Four weeks later 200,000 IU vit.A orally
(Week 4)
21. W.H.O.’s recommended doses
(for treatment of children under 1 year of age or <8 kg)
Immediately on diagnosis 100,000 IU vit.A orally
(Day 1)
The following day 100,000 IU vit.A orally
(Day 2)
Four weeks later 100,000 IU vit.A orally
(Week 4)
22. NOTE
• Preventive doses of vitamin A are also given
to pregnant women and those who are breast
feeding. But small daily doses than one
massive dose. The reason is to prevent any
possibility of a massive dose of vitamin A
being teratogenic to fetus.
• If massive dose is not available, then child
should eat food rich in vitamin A.
23.
24. Topical treatment to the eye
• Antibiotics
• Antiviral agents
• Padding an eye
• Closing the eyes
• Mydriatics
• No steroids
34. 4. Nutrition & health education
• Radio
• TV
• School etc.
Mothers will need advice about:
•Breast feeding
•Weaning in general
•How to prepare them, E.g. giving fried egg to
the child
•Liver, egg, cheese, butter, fish liver oil etc are
good sources of vitamin A.
5. Immunization
• Measles
5. Avoid traditional healers
• Herbs
• Tooth paste etc
