Presentation made from the Kanski,Wills eye manual,Harper,And Oxford handbook of ophthalmology.You dont need to read these books for VIRAL CONJUNCTIVITIS after reading this this presentation.
Conjunctivitis is an inflammation or swelling of the conjunctiva. The conjunctiva is the thin transparent layer of tissue that lines the inner surface of the eyelid and covers the white part of the eye. Often called "pink eye".
Bacterial conjunctivitis is a common type of pink eye, caused by bacteria that infect the eye through various sources of contamination. The bacteria can be spread through contact with an infected individual, exposure to contaminated surfaces or through other means such as sinus or ear infections.The most common types of bacteria that causes bacterial conjunctivitis includes Staphylococcus aureus, Haemophilus influenzae, Streptococcus pneumoniae and Pseudomonas aeruginosa. Bacterial conjunctivitis usually produces a thick eye discharge or pus and can affect one or both eyes.

Allergic conjunctivitis is inflammation of the conjunctiva (the membrane covering the white part of the eye) due to allergy.Although allergens differ among patients, the most common cause is hay fever. Symptoms consist of redness (mainly due to vasodilation of the peripheral small blood vessels), edema (swelling) of the conjunctiva, itching, and increased lacrimation (production of tears). If this is combined with rhinitis, the condition is termed allergic rhinoconjunctivitis.
The symptoms are due to release of histamine and other active substances by mast cells, which stimulate dilation of blood vessels, irritate nerve endings, and increase secretion of tears.
Treatment of allergic conjunctivitis is by avoiding the allergen (e.g., avoiding grass in bloom during "hay fever season") and treatment with antihistamines, either topical (in the form of eye drops), or systemic (in the form of tablets). Antihistamines, medications that stabilize mast cells, and nonsteroidal anti-inflammatory drugs (NSAIDs) are generally safe and usually effective.
The corneal diseases are one of the leading causes of blindness in the world. in most cases, these infections are preventable or treatable.
This seminar provides an overview of the anatomy and physiology of the cornea, as well as an overview of common conditions.

Trachoma History :-
Trachoma was previously known as Egyptian ophthalmia and endemic in the Middle East since prehistoric times.
Name comes from Greek word for ROUGH.
Other name :- Granular conjunctivitis, blinding trachoma, Egyptian ophthalmia
Trachoma is the most common infectious cause of blindness in the world Due to recurrent ocular infection with Chlamydia trachomatis.
Trachoma is the leading cause of preventable irreversible blindness in the world.
Repeat infection with this organism leads to conjunctival inflammation and scarring, trichiasis, and ultimately blinding corneal opacification
Epidemiology:-The World Health Organization (WHO) reports trachoma is endemic to more than 50 countries, with most blinding trachoma in Africa.
Worldwide, an estimated 2.2 million people are visually impaired as a result of trachoma, of whom 1.2 million are blind.
India has become free from Trachoma-with an overall prevalence found to be only 0.7% in the National Trachoma Survey Report (2014-17).
A Project on CONJUNCTIVITIS and HYPERTHYROIDISMUTSAV KUNDU
Conjunctivitis (also called pink eye in North America or Madras eye in India) is inflammation of the conjunctiva (the outermost layer of the eye and the inner surface of the eyelids).It is commonly due to an infection (usually viral, but sometimes bacterial) or an allergic reaction.
This presentation describes all clinical aspects of infectious corneal ulcers

Viral conjunctivitis shows a fine, diffuse pinkness of the conjunctiva, which is easily mistaken for the ciliary infection of Iris (Iritis), but there are usually corroborative signs onmicroscopy, particularly numerous lymphoid follicles on the tarsal conjunctiva, and sometimes a punctate keratitis.
Some other viruses that can infect the eye include Herpes simplex virus and Varicella zoster

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

Atrioventricular conduction blocks ( AV blocks ) are classified into 3 types.
This document describes the acute management of AV block.
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.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Scarring.
7. Signs(Cont’d):-
Keratitis(Adenoviral):
Epithelial microcysts in the early stage.
punctate epithelial keratitis:Usually occur in 7-10
days of onset of symptoms.Resolving in 2 weeks.
Anterior Stromal infiltrates/SEI:may persist for
months or years.
Anterior uveitis:
Usually mild.
8. Algorithm for Follicles:-
Follicles
Preauricular lymph nodes
Look for herpetic signs(e.g. dendrites,skin lesion)
Yes No
Source:Wills Eye Manual.
Yes No
HSV Adenovirus
Chlamydia
Toxic Conj.
Molluscum
Pediculosis
16. Spread of infection:-
Facilitated by
i)virus can survive on dry surfaces for weeks.
ii)Viral shedding may occur for many days before
clinical features are apparent.
Transmission by
i)Contact with Respiratory or ocular secretions.
ii)Via Contaminated Fomites such as Towels.
iii)Route of transmission is usually Eye-Hands-Eyes.
In Clinical setting,Eye-Instruments-Eye.
17. I)Epidemic Keratoconjunctivitis:-
Most severe presentation.
Caused by adenoviruses type 8,19 and 37.It is
markedly contagious.
incubation period after infection (8 days) & virus shed
from the inflamed eye for 2-3 weeks.
Keratitis occurs in 80% cases.
18. II)Non-specific acute follicular Conj.
Most common form of acute follicular conjunctivitis
Caused by adenovirus serotypes 1 to 11 & 19
Milder form of acute follicular conjunctivitis.
Unilateral symptoms, Other eye involved 1-2 days later,
but less severely.
Patient may have systemic symptoms such as sore
throat or common cold.
21. Herpes simplex Virus:-
Causes Follicular conjunctivitis particularly in
primary disease.
Usually unilateral.
Often Associated skin lesions.
Minute,Micro dendrites may be mistaken for punctate
epithelial keratitis,But Corneal sensation is reduced
in HSV (Source:Harper).
22. Acute hemorrhagic conjunctivitis:-
Usually occurs in tropical areas.
Caused by Enterovirus and coxsackie virus(Picorna
virus family).
Rapid onset,resolves within 1-2 weeks.
23. Molluscum Contagiosum:-
Caused by dsDNA pox virus.
Peak incidence of getting the virus is 2-4years.
Typically,Virus causes a skin lesion.
When skin lesion is on the lash line area of eyelid,it
causes viral shedding and follicular conjunctivitis.
Examine eyelash line carefully when
Chronic,unilateral eye irritation and mild discharge is
present.
27. TREATMENT
Adenoviral conjunctivitis:-
Supportive treatment for amelioration of symptoms is
the only treatment required and includes:
I)Artificial tears 4x/d.Preferably preservative free.
II)Topical Anti Histamines and vasoconstrictors.
III)Cold Compresses
IV)Discontinuation of contact lens wear.
29. Reduction of Transmission Risk:-
Meticulous hand hygiene.
Avoiding eye rubbing and towel sharing.
Disinfection of instruments and clinical surfaces after
examining an infected person.
31. Molluscum treatment:-
Usually the lesion is self-limiting in
immunocompetent patient.
Removal is needed to address secondary Conjunctivitis
or for Cosmetic reasons.
Expression by making a nick in the skin by a needle is
usually effective.
32. Herpes Simplex Treatment:-
Usually self limiting.
Topical antiviral drugs control the infection effectively
and prevent recurrences.
Supportive measures are similar with Adenoviral.
