Ulcerative Colitis: Case Presentation & Disease Overviewfarah al souheil
patient presenting with bloody stools and systemic signs with no previous medical complaints was diagnosed with amoebiasis on top ulcerative colitis (sigmoid-proctitis)
In this PPT presentation I try to teach many causes of Abdominal pain in various quadrants of the abdomen. Since it is individual case based teaching i concentrate only in the essential minimum an undergraduate medical student should know and you will have immersive learning experience.

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.

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

22. Definition:
• Intestinal Obstruction(IO) is a condition in
which there is a sudden stoppage of the
onward passage of intestinal contents-i.e. Gas,
digestive juices and food
25. Peristalsis is working against
a mechanical obstruction
DYNAMIC
(MECHANICAL)
Result from atony of the
intestine with loss of normal
peristalsis, in the absence of a
mechanical cause.
or it may be present in a non-
propulsive form (e.g. mesenteric
vascular occlusion or pseudo-
obstruction)
ADYNAMIC
(FUNCTIONAL)
26. Small or Large bowel
High (Proximal) or Low (Distal) small bowel
According to LEVEL
27. High IO- near the ampulla- jejunum and
proximal ileum.
Low IO- distal to the ampulla- distal ileum
and colon.
28.
29. According to nature of Obstruction:
1. Simple Obstruction- the bowel lumen is occluded ,blood supply remains
intact. The source of obstruction is usually intra-abdominal. ( Eg. Intra-
abdominal adhesions, very rarely gallstones, ball of worms, bezoars).
2. Strangulation- the bowel lumen together with its blood supply is cut-off.
Eg. Strangulated inguinal hernias. Pure strangulation without bowel
luminal narrowing is usually due to mesenteric embolism/thrombosis.
30. 3. Closed loop obstruction- The bowel is
obstructed both proximally and distally. Here
the blood supply may be impaired.
A classic example is seen in an obstruction of
the colon with a competent ileo-caecal valve.
NB: All the 3 types spoken about can occur at
the same time for example in a strangulated
inguinal hernia.
32. According to onset:
-Chronic Obstruction-Usually seen in large
bowel obstruction. The symptoms may arise
from the cause and the subsequent obstruction.
-Acute on Chronic Obstruction- sudden
obstruction in a previously incomplete
obstruction.
Sub-acute Obstruction- There is a partial
obstruction.
38. Clinical presentation
The clinical presentation varies according to;
- The location of the obstruction
- The age of the obstruction
- Underlying pathology
- Presence or absence of intestinal ischaemia.
39. Clinical features
• Abdominal pain
• Vomiting
• Distension
• Constipation
• Dehydration
• Feature of toxemia and septicemia
• Feature of strangulation
• Temperature
• Bowel sound
• Per rectal examination
42. A. Investigations

requested on the basis of clinical suspicion.
(ii)Diagnostic
