Allergic rhinitis is a very common disorder that affects people of all ages. It is frequently ignored, under diagnosed, misdiagnosed, and mistreated, which not only is detrimental to health but also has societal costs. Although allergic rhinitis is not a serious illness, it is clinically relevant because it underlies many complications, is a major risk factor for poor asthma control, and affects quality of life and productivity at work or school. Hidden direct costs include the treatment of co-morbid asthma, chronic sinusitis, otitis media, upper respiratory infection, and nasal polyp. Nasal congestion, the most prominent symptom in AR, is associated with sleep-disordered breathing, a condition that can have a profound effect on mental health, including increased psychiatric disorders, depression, anxiety, and alcohol abuse. Furthermore, sleep-disordered breathing in childhood and adolescence is associated with increased disorders of learning performance, behavior, and attention. Management of allergic rhinitis is best when directed by guidelines. At this juncture Homoeopathic system of medicine offers a safe and effective solution of the illness if followed under the guidance of expertise. This article provides an overview of the patho-physiology, diagnosis, and appropriate homoeopathic management of this disorder.

Pulmonary Thromboembolism - etilogy, types, medical- Surgical and nursing man...VarunMahajani
Disruption of blood supply to lung alveoli due to blockage of one or more pulmonary blood vessels is called as Pulmonary thromboembolism. In this presentation we will discuss its causes, types and its management in depth.
The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

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.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

2. Definition
“IgE mediated hypersensitivity disease of mucous membranes of
nasal airways characterized by sneezing, watery nasal discharge ,
itching and nasal obstruction” (Durham, 1999)
3. Prevalence
• Global health problem
• Prevalence - 15% and 20% (Nathan et al.,1999)
• Higher in pediatric age group(Wright et al.,1994)
• Approx. 80% develop symptoms before age of 20
(Skoner et al., 2001)
4. • Not a severe disorder but significantly
alters patient’s social life
-school performance
-work productivity
• Substantial cost
Impact on quality of life
5. Risk factors
1. Genetic susceptibility:
2. Family history of atopy: e.g. asthma,eczema,hay
fever,urticaria
(Genes involved in atopy - loci on 5q,11q and 12q
chromosomes)
3. Environmental factors:
• Pollution-climate interaction
• Irritants
eg. fumes, tobacco smoke, diesel exhaust,
mosquito repellents, perfumes, scented sticks,
domestic sprays, bleaches
4. Exposure to allergens:
• Seasonal : Pollen, Fungus
• Perennial: Dust mite, domestic pets, cockroaches
6. 5.Hygiene hypothesis
• Increased exposure to various allergensimmune maturationhelp decrease
the incidence of allergic diseases and asthma (Svanes C et al., 2003)
• Early environmental exposure to infectious agents, protects against
development of atopy (Tulic MK et al.,2003)
• Early nursery attendance also reduces subsequent atopy (Kramer et al.,2003)
• Lack of immune maturation (understimulated immune system) in
infancyallergic responses (Liu A,2007)
7. Pathogenesis
• Sensitization & Priming to specific antigen:
Inhaled allergen produces specific IgE antibody
which gets attached to mast cells
• Subsequent exposure to same antigen:
Allergen combines with specific IgE antibody ®
degranulation of mast cells ® chemical mediators
released
8.
9. Acute or early phase response
• Occurs 5–30 min after antigen exposure
• Release of inflammatory mediators
· Increased nasal gland secretion ® runny nose
· Mucosal edema & Vasodilation ® nose block
· Nerve irritation ® sneezing & itching
10. Late or delayed phase response
• Occurs 2-8 hours after antigen exposure
• Infiltration by inflammatory cells
(eosinophils, neutrophils, basophils,
monocytes & CD4+ T lymphocytes)
• Edema, congestion & thick nasal secretion
• Sneezing & itching decreases
16. Seasonal allergic rhinitis
Pollen:
Spring (March-June) = Tree pollen
Summer (May-August) = Grass
Fall (August-October) = Weeds
Mold:
Spores in outdoors have seasonal
variation (reduced in winter, increased in
summer/fall due to humidity)
House dust mites:
Generally “perennial” allergen,
but increased in damp autumn months
17. Perennial allergic rhinitis
Fungi/mold:
Exposure peaks accompany activities
such as harvesting & cutting grass
Pet dander (cats, dogs):
up to 4 months after pet removal
House dust mites:
Live in bedding & carpets
Cockroaches:
Respiratory allergy
Important allergen
18. Diagnosis
1.History
2.Physical exam
3.Allergy diagnosis
(I) Skin prick test (SPT)
(II) Blood tests for allergy: Total IgE, Specific IgE
(III) Nasal allergen challenge test
21. Skin Prick test
Advantages:
1. Cheap
2. Immediate result
3. Sensitive
Contraindications:
1. Patients on antihistamines
2. Severe eczema
3. Previous anaphylaxis
4. Dermagraphism
22. (II) Blood tests for allergy
1.Total IgE:
Rarely helpful as 50% pts have IgE levels within normal range
2.Specific IgE:
(i) Radio-allergosorbent test (RAST) (ii)Modified RAST
Stabilized allergen is incubated with patient’s serumany specific IgE binds to
allergen identified by a second incubation with labelled anti-IgE.
23. Radio-allergosorbent test (RAST)
Indications:
1. When there is C/I to SPT
2. Where SPT unavailable
3. When SPT difficult to interpret
Disadvantages:
More expensive
Delayed(takes longer)
No more sensitive or specific to SPT
27. • Nasal symptoms -noted 80% of
asthmatics
• Adults-Asthma present in 22.5% of
adults with AR, Vs 7.2% in general
population (Laynaert, 1999 )
• Children-Ratio of asthmatics with AR to
asthmatics without AR is even higher
(Wright et al.,1996)
• Effective treatment of allergic rhinitis
reduces development of subsequent
asthma (Ragab et al., 2006)
28. Differential diagnosis
1.Vasomotor rhinitis (Intrinsic rhinitis/NANIPER)
2.Sinonasal polyposis
3.Rhinitis medicamentosa
4.Hormonal rhinitis
(Pregnancy, Hypothyroidism, OCP use )
5.CSF leak
Take a moment to consider
differential diagnosis
29.
30. Management of allergic rhinitis
1. Environmental control measures (Avoidance of allergens)
2. Patient education
3. Nasal douching
4.Medical therapy
5.Immunotherapy
6.Surgery
31. (I) Avoidance of allergens
• Best treatment method
• Not always practical
• Indoor allergens: Removing allergen from the indoor
environment should be a primary strategy for the management
and treatment of allergic disease
• Outdoor allergens:
32. General advice
• Avoid irritants: smoke, dust, vehicular & other atmospheric pollutants,
• Physical factors – extreme changes in temperature can produce symptoms
like allergic rhinitis but are non-IgE mediated responses
• Avoid foods & drugs to which you are allergic
• Avoid occupational irritants or change profession
34. Avoidance of animal allergen
• Remove pet animals (cats, dogs)
from bedroom
• Wash the pet weekly
35. Measures to avoid house dust mite
• Mattress covers
• Covers for pillows & bedding
• Vacuuming
• Regulation of ventilation & humidity at home
• Liquid nitrogen
• Acaricides
• Protein denaturating agents- Tannic acid
36. Pollen avoidance measures
• Avoid walking in open grassy spaces
during hot, dry days
• Keep windows closed
• Wear facemask & sunglasses when
moving out
37. (II) Patient education
Educate patients on environmental control measures,
which involve both the avoidance of known allergens
(substances to which the patient has IgE-mediated
hypersensitivity) & the avoidance of nonspecific, or
irritant, triggers
38. (III) Nasal douching
•Saline irrigation
•Improves quality of life
Neti Pot: Home remedy to clean nasal passages
42. Steroid
• Most effective treatment for Allergic rhinitis(AR)
-Topical: Nasal spray or nasal drop
-Systemic:Oral, extremely effective
• Reduces inflammation & consequent
hyperreacitvityreduce nasal symptoms, eye
symptoms, improve smell sense
• Topical steroid when combined with antihistamines
reduces risk of asthma exacerbation and hospitalization
by 50% or more (Adams et al., 2002, Crystal peters et
al., 2002)
• Fluticasone and mometasone have low systemic
bioavailabilitylower risk
43. Antihistamines
• Adverse effects of first generation antihistamines
“First-generation oral H1-antihistamines are not recommended when second-generation
ones are available, due to safety concerns”
(Allergy. 2008 Apr;63 Suppl 86:8-160)
47. Decongestants
• Topical vasoconstrictor:
-imidazoline (eg, oxymetazoline)
• systemic (oral) vasocontrictor
-Phenylephrine
- Pseudoephedrine.
• Monotherapy with vasoconstrictors has limited role
• Oral decongestants + Antihistamineall cardinal
symptoms of allergic rhinitis targeted
48. Mast cell stabilizer
• Sodium cromoglycate inhibits degranulation of
sensitized mast cells
• 2% Nasal drop: Use 3 to 4 times daily limits
compliance
• Poorly absorbed systemically excellent safety
record
• Used before the onset of symptoms
• Can be used in younger children < 2 years of age
Ipratropium Bromide
• Useful against nasal discharge
• Occasionally helpful in pts with AR who do not
respond to topical steroid(Dockhorn et al., 1999)
49. Antilukotrienes
Zafirlukast performed no better than placebo - seasonal alllergic
rhinitis ( Pullerits T et al., 1999)
• Montelukast clinical efficacy seasonal Allergic rhinitis
(Chervinsky P et al., 2004)
• Montelukast + loratadine -superior reducing day time nasal
symptoms in seasonal Allergic rhinitis. (Meltzer EO et al., 2000)
• Montelukast + ebastine- better symptomatic control in allergic rhinitis.
• Montelukast -less effective than Intranasal steroid (Ratner PH et al.,
2003)
• Leukotriene antagonist (Montelukast) doesn’t appear more effective
than nonsedating antihistamines (Fexofenadine) (Wilson AM et al., 2004)
50. (V) Immunotherapy
• Repeated administration of allergen extract
induce state of immunological tolerance
• Render an allergy patient less symptomatic
when exposed to the offending antigen
• Desensitization or Hyposensitization:
because complete elimination of the allergic
reaction is seldom achieved
• Subcutaneous injection or sublingual route
51. Contraindications
• Asthma(severe)
• Autoimmune diseases
• Beta-blockers or Anti-adrenergic medicines
• Children less than < 5 yrs
• Pregnancy (induction but not maintenance)
• Efficacy:
• Highly effective -selected patients (Grade A)
• Treatment for 3 to 4 yrs –improvement for 3 yrs following discontinuation
(Durham SR et al.,1999)
• Children –seasonal rhinitis-ITX for 3 yrs-2 to 3 fold reduction –developing
asthma (Moller et al.,2002)
• Offers long term disease modification & prophylaxis
52. Side effects of Immunotherapy
Local reactions - trivial
Systemic reactions-10%-up dosing phase
Occasionally – severe systemic reactions-general
urticaria , severe asthma or
anaphylaxis
53. (VI) Surgery
• Usually not indicated
• Not last resort but complementary
• Comorbid or complicating conditions eg
Marked DNS, Turbinate hypertrophy, CRS
54. (VII) Complementary and integrative medicine(CIM) therapies
• Honey – For seasonal AR caused by pollen
• Chinese herbal medicine
• Acupuncture
55. Recent advances
(VIII) Human monoclonal antibody(Anti-IgE)
• Omalizumab - recent developments in the treatment of atopic
diseases
first of several monoclonal antibodies (anti IgE antibody)
Modulation of allergic inflammation
expensive for routine treatment of AR primarily indicated -severe
asthma
• Multiple randomized, double-blind, placebo-controlled studies
-efficacy in seasonal and perennial AR (Vignola AM et al.,2004)
Continued research on the molecular mechanism of
allergic disease will inevitably generate new forms of
therapy.

Editor's Notes
Furthermore, the GA2 LEN (Global Allergy and Asthma European Network) task force assessed the unwanted side-effects and potential dangers of first-generation H1-antihistamines by reviewing the literature.
The therapeutic window of H1 antihistamine is the dose range over which it is efficacious and also free from unwanted side effects. The lower limit of the therapeutic window is set by the lowest clinically effective dose for the disease condition whereas the upper limit is set by the highest dose tolerated without adverse effect.
As an example, fexofenadine has a wide therapeutic window. It is effective at a dose of 60 mg and is free from sedation at 690 mg twice daily (1380 mg).
