Infectious coryza is an acute respiratory disease of chickens characterized by nasal discharge, sneezing, and swelling of the face under the eyes. It is found worldwide. The disease is seen only in chickens; reports of the disease in quail and pheasants probably describe a similar disease that is caused by a different etiologic agent.
Canine parvovirus (CPV) is a highly contagious and relatively common cause of acute, infectious GI illness in young dogs. Although its exact origin is unknown, it is believed to have arisen from feline panleukopenia virus or a related parvovirus of nondomestic animals. It is a nonenveloped, single-stranded DNA virus, resistant to many common detergents and disinfectants, as well as to changes in temperature and pH. Infectious CPV can persist indoors at room temperature for at least 2 mo; outdoors, if protected from sunlight and desiccation, it can persist for many months and possibly years.
Fowlpox is contagious viral disease.
Bird of all age is affected by this disease.
Chicken and turkeys are mainly affected by this disease.
Some viral type may also affect pigeon, geese, pheasants and quills.
1-2% mortality rate.
Incubation period 2-3 weeks.
Fowlpox is seen worldwide.

2 Case Reports of Gastric Ultrasound
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.

CDSCO and Phamacovigilance {Regulatory body in India}NEHA GUPTA
The Central Drugs Standard Control Organization (CDSCO) is India's national regulatory body for pharmaceuticals and medical devices. Operating under the Directorate General of Health Services, Ministry of Health & Family Welfare, Government of India, the CDSCO is responsible for approving new drugs, conducting clinical trials, setting standards for drugs, controlling the quality of imported drugs, and coordinating the activities of State Drug Control Organizations by providing expert advice.
Pharmacovigilance, on the other hand, is the science and activities related to the detection, assessment, understanding, and prevention of adverse effects or any other drug-related problems. The primary aim of pharmacovigilance is to ensure the safety and efficacy of medicines, thereby protecting public health.
In India, pharmacovigilance activities are monitored by the Pharmacovigilance Programme of India (PvPI), which works closely with CDSCO to collect, analyze, and act upon data regarding adverse drug reactions (ADRs). Together, they play a critical role in ensuring that the benefits of drugs outweigh their risks, maintaining high standards of patient safety, and promoting the rational use of medicines.

Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path
3. INTRODUCTION
• Isolated from Cerumen by Jakob Henle (1841)
• Gustav Simon described as Acarus folliculorum
(1842)
• Demodex coined by Richard Owen (1843)
4. DEMODEX
• Obligate Pilosebaceous gland parasites – Man /
Dogs / Cats (Mange)
• 02 main species :
D. Folliculorum
(Longer 0.2 – 0.4 mm)
D. Brevis
(0.1 – 0.2 mm / Sebaceous)
7. PATHOGENESIS
• Contain Lipase ; found in areas high with sebum viz
forehead, cheeks, nasolabial folds, scalp, external ear, in eyelash
follicles meibomian glands, upper chest and nipples
• D. folliculorum - head-down position in the follicle, often with the
tip of the abdomen protruding from the follicular orifice.
• Follicle mites are quite motile, and migrate from follicle to follicle.
Most infested follicles contain two to six mites, but occasionally
they are much more numerous.
• Mites have been isolated from individuals of all ages, except
neonates (close maternal contact?)
• Prevalence inc with age
• Skin-surface biopsy / scraping identifies clusters
8. CLINICAL FEATURES
• 02 distinct presentations:
• 1) PITYRIASIS FOLLICULORUM
Earlier described in Middle-aged or older women who rarely
washed their faces, but used large quantities of make-up and
cleansing creams.
Diffuse facial erythema and follicular plugs, which impart a
‘nutmeg grater’ appearance to the skin
Skin scrapings contained unusually large numbers of Demodex
10. CLINICAL FEATURES
•
2) ROSACEA-LIKE ERUPTION
Rosacea merely provides Environment for multiplication of the mites, or whether the
mites play a role in initiating the disease.
?Local, delayed hypersensitivity response to Demodex antigens - inflammatory
component of rosacea
Bacterial antigens associated with Bacillus oleronius, isolated from D. folliculorum,
stimulate inflammatory response in PapuloPustular rosacea
Extrafollicular Demodex or fragments of Demodex may be found in the granulomatous
lesions of rosacea – immune-mediated destruction and extrusion of mite remains
Mite identified from Papulo-Pustular Rosacea but not from Pustular Acne
Response to Miticidal agents, not to Metronidazole
11. CLINICAL FEATURES
• Implicated in papular and papulopustular lesions in
immunosuppressed indls - Leukemia / MF / HIV-positivity
• Facial lesions attributed to Demodex have been described in
immunocompetent children
• D. folliculorum density in perioral dermatitis suggested that
increased mite density was a secondary phenomenon related to
topical steroids, and also showed that mite density increased
significantly in relation to the length of treatment
• Presence in Eyelash follicles has been implicated in the
pathogenesis of blepharitis
12. OTHER ASSOCIATIONS
• Fungal spores and Mycobacterium leprae within
Demodex mites – Vectors ??
• LMDF
• SEBORRHOEIC DERMATITIS
• GROVER’S DISEASE
• AGA
18. TREATMENT
• Cleansing with Soap / Water
• Miticidal agents – Benzoyl Benzoate / Lindane
