This document discusses gastroesophageal reflux disease (GERD). It defines GERD as a condition where the abnormal reflux of gastric contents into the esophagus causes symptoms or mucosal damage. It discusses the epidemiology, pathophysiology involving breakdown of the lower esophageal sphincter barrier, clinical manifestations including typical and atypical symptoms as well as complications. It outlines the diagnostic evaluation including clinical diagnosis, endoscopy, and pH monitoring. It also details treatment approaches including lifestyle modifications, antacids, H2 receptor antagonists, proton pump inhibitors, and in some cases surgery or endoscopic interventions.

Definition
Gastro esophageal reflux disease is a chronic and relapsing condition in which prolonged reflux of hydrochloric acid, pepsin and bile salts in the esophagus, oral cavity and respiratory system occurs that leads to esophagitis
Excessive intake of junk foods, coffee, chocolate
Excessive intake of onion, tomato, and beverages
Heavy exercise
Alcoholic and smoking
Medications
Heartburn
Discomfort
Chest pain
Difficulty in respiration
Aspiration pneumonia
After endoscopy the lesions are graded for severity using the Savary Miller grading system;
Grade 1: single or multiple erosions on a single fold.
Grade 2: multiple erosions affecting multiple folds. Erosions may be confluent.
Grade 3: multiple circumferential or rounded erosions.
Grade 4: ulcer, stenosis or esophageal shortening.
Grade 5: Barrett's epithelium. Columnar metaplasia (cellular changes on the microscopic level) in the form of circular or non-circular (islands or tongues) extensions.
Pathophysiology
Management
Antacids: An antacid is a substance which neutralizes stomach acidity, used to relieve heartburn, indigestion or an upset stomach (ex: Rantac, Zantac)
H2receptor antagonist: H2 antagonists block histamine-induced gastric acid secretion from the parietal cells of the gastric mucosa. They include cimetidine, famotidine, nizatidine
Proton Pump Inhibitors: Proton pump inhibitors (PPIs) reduce the production of acid by blocking the enzyme in the wall of the stomach that produces acid (Omeprazole, Rabeprazole, pantoprazole)
Cholinergic drugs:Cholinergic drug, any of various drugs that inhibit, enhance, or mimic the action of the neurotransmitter (acetylcholine, carbachol, methacholine)
Cytoprotective drugs: is a process by which chemical compounds provide protection to cells against harmful agents (carbenoxolone, sucralfate, misoprostol)
Prokinetic drugs: prokinetic, is a type of drug which enhances gastrointestinal motility by increasing the frequency of contractions in the small intestine or making them stronger, but without disrupting their rhythm. (Benzamide, Cisapride, Domperidone).
Endoscopic intraluminal valvuloplasty
Gastric tissue is utilised to increase the integrity of LES By creating a valve like structure.
GERD is a day to day common problem, which is on the increase due to so many obvious reasons. It needs to be addressed to the public and the medical fraternity for proper management and treatment.

Gastroesophageal Reflux
Gastroesophageal reflux that does not cause symptoms is known as physiologic reflux. In nonerosive reflux disease (NERD), individuals have symptoms of reflux disease but no visible or minimal esophageal mucosal injury
Gastroesophageal reflux disease (GERD) is the reflux of acid and pepsin or bile salts from the stomach to the esophagus that causes esophagitis. The severity of the esophagitis depends on the composition of the gastric contents and esophageal mucosa exposure time.
Definition & Classification
Gastroesophageal Reflux
Causes
GERD can be caused by abnormalities or alterations in
1. Lower esophageal sphincter function
2. Esophageal motility
3. Gastric motility or emptying
Esophageal function studies include the following:
Determination of the lower esophageal sphincter (LES) pressure (manometry)
Graphic recording of esophageal swallowing waves, or swallowing pattern (manometry)
Detection of reflux of gastric acid back into the esophagus (acid reflux)
Detection of the ability of the esophagus to clear acid (acid clearing)
An attempt to reproduce symptoms of heartburn (Bernstein test)
Gastroesophageal Reflux
Risk Factors
Obesity
Hiatal hernia
Use of drugs or chemicals that relax the LES (anticholinergics, nitrates, calcium channel blockers, nicotine)
Cigarette smoke.
Trigger Factors
Coughing
Vomiting
Straining at stool
Asthma
Chronic cough
Sinusitis.
Gastroesophageal Reflux
Common Symptoms
Heartburn that occurs 30 to 60 minutes after meals and when the patient bends over or lies down.
Regurgitation of sour or bitter gastric contents
Belching, and fullness of the stomach
Upper abdominal pain within 1 hour of eating.
Atypical Symptoms
chronic cough
asthma attacks
chronic laryngitis
sinusitis
discomfort during swallowing.
Noncardiac chest pain.
Dysphagia
Gastroesophageal Reflux
Clinical manifestations are related to mucosal injury from acid regurgitation and the frequency and duration of reflux events.
The symptoms worsen if the individual lies down or if intraabdominal pressure increases because of coughing, vomiting, or straining at stool.
Uncomplicated GERD that is responsive to first-line therapy does not require an endoscopy.
Patients who do not respond to therapy and those with suspected complications should undergo an endoscopic examination
Management & Evaluation
Differential diagnosis
Gastritis
Peptic ulcer
Gastric cancer
Cholelithiasis
Angina pectoris.
Gastroesophageal Reflux
Diagnosis of GERD is based on the history and clinical manifestations.
An upper endoscopy with biopsy is the standard diagnostic procedure for GERD. It confirms the diagnosis and documents the type and extent of tissue damage.
Esophageal endoscopy: shows hyperemia ...
GERD | Gastro esophageal reflux disease-a brief medical study martinshaji
Gastro esophageal reflux disease (GERD) is a chronic digestive disease. GERD occurs when stomach acid or, occasionally, stomach content, flows back into your food pipe (esophagus). The backwash (reflux) irritates the lining of your esophagus and causes GERD. This is a very common condition observed

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

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

2. Definition of GERD
Epidemiology of GERD
Pathophysiology of GERD
Clinical Manisfestations
Diagnostic Evaluation
Treatment
Complications
3. Symptoms OR mucosal damage
produced by the abnormal reflux of
gastric contents into the esophagus
Often chronic and relapsing
May see complications of GERD in
patients who lack typical symptoms
5. GERD occurs in all ages but, most common
in those older than 40 years of age.
About 10-20% of people in western countries
suffer from GERD symptoms on a weekly
basis
About 7% have symptoms daily.
Except for NERD and pregnancy , no much
difference in incidence between men and
women.
But for Barrett’s esophagus, prevalence is
more in males particularly white adult
males.
6. Primary barrier to gastro esophageal reflux is the
lower esophageal sphincter
LES normally works in conjunction with the
diaphragm
If barrier disrupted, acid goes from stomach to
esophagus
May be due to
Spontaneous transient LES relaxations
Transient increase in intra abdominal pressure
An atonic LES
7. Drugs that reduce LES tone include calcium
channel antagonists (e.g., nifedipine,
verapamil, diltiazem), nitrates,
anticholinergic agents(e.g.,tricyclic
antidepressants , antihistamines), and oral
contraceptives and estrogen.
Foods that reduce LES tone include
chocolate, fatty foods , onions, peppermint,
and garlic
Smoking(nicotine) reduces LES tone.
8. 2)DISRUPTION OF ANATOMICAL BARRIERS
Associated with hiatal hernia
The size of hiatal hernia is proportional to the frequency of
LES relaxations
Hypotensive LES pressures and large hiatal hernia- more
chance of GERD following abrupt increase in intra abdominal
pressure
3) ESOPHAGEAL CLEARANCE
The GI acid produced spent too much time in contact with
the esophageal mucosa
Normally swallowing contributes to esophageal clearance by
increasing salivary flow
Saliva decreases with increasing age, so more often seen
with elderly.
9. 4)MUCOSAL RESISTANCE
The mucus secreated by the mucus secreting glands
involves in the protection of esophagus
The bicarbonate s moving from the blood to the lumen
can neutralize acidic refluxate in the esophagus. On
repeated exposure to the refluxate or due to some
defect in normal mucosal defenses hydrogen ions
diffuse into the mucosa, leading to cellular
acidification and necrosis leading to esophagitis.
5)DELAYED GASTRIC EMPTYING
An increase in gastric volume may increase both the
frequency of reflux and the amount of gastric fluid
available to be refluxed
Physiologic Postprandial Gastro esophageal reflux
occurs
10. 6)COMPOSITION OF REFLUXATE
If the pH of the refluxate is less than 2, esophagitis may
develop secondary to protein denaturation
Also pepsinogen activated to pepsin at this pH may cause
esophagitis.
11. Erosive esophagitis
Responsible for 40-60% of GERD symptoms
Severity of symptoms often fail to match severity
of erosive esophagitis
12. Esophageal stricture
Result of healing of
erosive esophagitis
May need dilation
Common in the distal
esophagus and are
generally 1 to 2 cm in
length.
13. Barrett’s Esophagus
Columnar metaplasia of the esophagus,i.e
replacement of the squamous epithelial lining of
the esophagus by specialized columnar- type
epithelium
Associated with the development of
adenocarcinoma
Have a greater chance (30%) of developing
esophageal stricture
14. Barrett’s Esophagus
Acid damages lining of
esophagus and causes
chronic esophagitis
Damaged area heals in a
metaplastic process and
abnormal columnar cells
replace squamous cells
This specialized intestinal
metaplasia can progress to
dysplasia and
adenocarcinoma
15. 3 CLASSES OF SYMPTOMS
TYPICAL SYMPTOMS
May be aggravated by activities that worsen
gastroesophageal reflux such as recumbent
position, bending over, or eating a meal high in
fat.
Heartburn—retrosternal burning
discomfort
Regurgitation—effortless return of gastric
contents into the pharynx without nausea,
retching, or abdominal contractions
Water brash (hyper salivation)
Belching
16. ATYPICAL SYMPTOMS
In some cases, these extra esophageal symptoms may be
the only symptoms present, making it more difficult to
recognize GERD as the cause, especially when
endoscopic studies are normal.
Nonallergic asthma
Hoarseness
Pharyngitis
Chest pain
Dental erosions
17. ALARM SIGNS/SYMPTOMS
These symptoms may be indicative of
complications of GERD such as Barrett’s
esophagus, esophageal strictures, or
esophageal cancer
Dysphagia
Early satiety
GI bleeding
Odynophagia
Vomiting
Unexplained Weight loss
Iron deficiency anemia
Choking
Continual pain
18. If classic/typical symptoms like heartburn and
regurgitation exist in the absence of “alarm
symptoms” the diagnosis of GERD can be made
clinically and treatment can be initiated
19. H2RA or PPI
Expect response in 2-4 weeks
If no response
Change from H2RA to PPI
Maximize dose of PPI
If PPI response inadequate despite maximal
dosage
Confirm diagnosis
EGD(Esophagogastrodudenoscopy)
24 hour pH monitor
20. Endoscopy (with biopsy if
needed)
In patients with alarm
signs/symptoms
Those who fail a medication trial
Those who require long-term
treatment
Important in distinguishing
between esophagitis and Barret’s
metaplasia
Absence of endoscopic features
does not exclude a GERD
diagnosis
Confirmation can be achieved by
provocative tests such as an acid
perfusion test(Bernstein test),
standard acid reflux test etc.
21. 24-hour pH monitoring
Helps in establishing the presence of acid above
the LES as the cause of symptoms or esophageal
damage.
Documents the amount of time the esophageal
pH is low.
Useful in patients who have not responded or
who have had an incomplete response to empiric
therapy, have symptoms with out evidence of
mucosal injury, or have atypical symptoms.
Trans-nasal catheter or a wireless, capsule
shaped device
22. Patient with heartburn
Iniate tx with H2RA or PPI
H2RA taken
BID
Good response
Frequent relapses
On demand tx
PPI taken QD
Good response
Maintenance therapy
with lowest effective dose
Symptoms persist
Consider EGD if
risk factors present
(> 45, white, male
and > 5 yrs of sx)
Increase to
max dose QD
or BID
Good response
Confirm diagnosis
EGD, ph monitor
No
Yes Yes
No
Yes
Yes
No
No
23. Goals of therapy
Alleviate or eliminate the patients symptoms.
Decrease the frequency or recurrence and
duration of gastro esophageal reflux.
Promote healing of the injured mucosa.
Prevent the development of complications.
24. Lifestyle modifications
Avoid large meals
Avoid acidic foods (citrus/tomato), alcohol, caffiene, chocolate,
onions, garlic, peppermint
Decrease fat intake
Avoid lying down within 3-4 hours after a meal
Elevate head of bed 4-8 inches
Avoid meds that may potentiate GERD (CCB, alpha agonists,
theophylline, nitrates, sedatives, NSAIDS)
Avoid clothing that is tight around the waist
Lose weight
Stop smoking
25. Antacids
Over the counter acid
suppressants and antacids
appropriate initial therapy
Approx 1/3 of patients with
heartburn-related symptoms use
at least twice weekly
More effective than placebo in
relieving GERD symptoms
26. Histamine H2-Receptor Antagonists
Competitively block the histamine receptors in
gastric parietal cells, thereby preventing acid
secretion
More effective than antacids for relieving
heartburn in patients with GERD
Faster healing of erosive esophagitis
Can use regularly or on-demand
28. Proton Pump Inhibitors
Effective not only with patients having erosive
esophagitis or complications(Barret’s esophagus),
but also with non erosive GERD who have
moderate to severe symptoms.
Act by decreasing the basal and stimulated
gastric acid secretion through inhibition of the
final step of acid secretion by the parietal cell-
the H+/K+ ATPase proton pump.
Better control of symptoms with PPIs vs H2RAs
and better remission rates
Faster healing of erosive esophagitis with PPIs vs
H2RAs
30. H2RAs vs PPIs
12 week freedom from symptoms
48% vs 77%
12 week healing rate
52% vs 84%
Speed of healing
6%/wk vs 12%/wk
31. Antireflux surgery
Failed medical management
Patient preference
GERD complications
Medical complications attributable to a large
hiatal hernia
Atypical symptoms with reflux documented on
24-hour pH monitoring
32. Postsurgery
10% have solid food dysphagia
2-3% have permanent symptoms
7-10% have gas, bloating, diarrhea, nausea, early
satiety
Within 3-5 years 52% of patients back on
antireflux medications
33. Endoscopic treatment
Relatively new
No definite indications
Select well-informed patients with well-
documented GERD responsive to PPI therapy
may benefit
Three categories
Radiofrequency application to increase LES
reflux barrier
Endoscopic sewing devices
Injection of a nonresorbable polymer into LES
area
