Syncope, or fainting, is a relatively common problem that is often misdiagnosed. It is caused by a temporary drop in blood pressure and loss of consciousness. The most common causes are neurally-mediated syncope, cardiac arrhythmias, and orthostatic hypotension. A thorough history, physical exam, and diagnostic tests like carotid sinus massage and tilt table testing can help identify the underlying cause. Treatment depends on the cause but may include lifestyle changes, medications, or pacemaker implantation in severe cases. Proper diagnosis and management of syncope is important as it can occasionally lead to injuries or accidents.
this lecture explains Syncope which is a transient loss of consciousness from many points: the definition, causes, next step, history and physical examination from evidence based resources as the UpToDate and the European society of cardiology guidelines 2018.

Death by Neurological Criteria and Organ Donation: Bill KnightSMACC Conference
Bill Knight explains the concept of death by neurological criteria and the complexities surrounding organ donation in such situations.
Bill discusses the process of dying, the definition of death, how to approach the neurologically dead patient and how to consider organ donation.
Death is a complex topic.
Due to advancements in medical technology and processes, the definition of death is a challenging one.
Bill talks at length about the definition of death by the neurological criteria. Dying is an active process, whereas death is an event.
The acceptance of death by the neurological criteria is often challenging as Bill will highlight. Bill talks about the care of the dying or dead patient.
There is a point at which care will transition from supporting the patient to supporting the organs. This is still good care.
There is an alignment of parallel intentions – first and foremost resuscitation of patients and then failing that, proceeding to considering and actioning organ donation. This is important due to the shortage of viable donor organ worldwide.
The donation process itself is complex. Bill provides his thoughts. He insists that an intensivist be involved as this has been shown to increase the number of viable and healthy organs made available.
The timing is also important. Available evidence does not support the need for immediate procurement after brain death. Taking time to optimise perfusion and allow recovery and cardiac function is appropriate and should be done.
Bill also discusses other treatment options at the time of death such as optimising endocrine function.
Finally, Bill will provide some practical considerations when communicating with the dead patient’s family. This involves being clear on your messaging. You are supporting organs, not life.
To reinforce this point, Bill suggests not examining or talking to the patient. He also recommends using all of the available hospital support services.
Similarly, it is best to not introduce the topic of organ donation to the family yourself as the treating clinician. Utilise the Organ Procurement Organisations (or similar services) and get them involved early to speak with the family.
Join Bill Knight in his talk on the North American perspective on Organ Donation, brain death and management of the brain dead donor prior to organ donation.

Title: Sense of Smell
Presenter: Dr. Faiza, Assistant Professor of Physiology
Qualifications:
MBBS (Best Graduate, AIMC Lahore)
FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
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

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.

Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

There is severe impairment of neurocardiovascular reflex which leeds to pooling of a significant of blood in the leg vessels.
Stimulation of baro receptors in the carotid body would send neuronal signals to NTS in the brain stem via glossopharyngeal nerve.This inturn would lead to increased parasympathetic nervous tone, inhibiting SA and AV node causing bradycardia.There is also sympathetic withdrawl leading to vasodilataion and hypotension.
