Upper GI tract bleeding can present with hematemesis (vomiting of blood) which resembles coffee grounds, indicating bleeding from the esophagus, stomach or duodenum. Common causes include peptic ulcers, esophageal varices, erosive gastritis, esophagitis, Mallory-Weiss syndrome, stomach cancer, and bleeding disorders. Peptic ulcers are caused by an increase in acid secretion or a decrease in mucosal resistance. Esophageal varices develop due to portal hypertension from liver cirrhosis. Management of upper GI bleeding involves intravenous fluids, monitoring, and endoscopy within 24 hours to control bleeding.
Approach to Management of Upper Gastrointestinal (GI) BleedingArun Vasireddy
Upper gastrointestinal bleeding is gastrointestinal bleeding in the upper gastrointestinal tract, commonly defined as bleeding arising from the esophagus, stomach, or duodenum. Blood may be observed in vomit (hematemesis) or in altered form in the stool (melena). Depending on the severity of the blood loss, there may be symptoms of insufficient circulating blood volume and shock. As a result, upper gastrointestinal bleeding is considered a medical emergency and typically requires hospital care for urgent diagnosis and treatment. Upper gastrointestinal bleeding can be caused by peptic ulcers, gastric erosions, esophageal varices, and some rarer causes such as gastric cancer.
The initial assessment includes measurement of the blood pressure and heart rate, as well as blood tests to determine hemoglobin concentration. In significant bleeding, fluid replacement is often required, as well as blood transfusion, before the source of bleeding can be determined by endoscopy of the upper digestive tract with an esophagogastroduodenoscopy. Depending on the source, endoscopic therapy can be applied to reduce rebleeding risk. Specific medical treatments (such as proton pump inhibitors for peptic ulcer disease) or procedures (such as TIPS for variceal hemorrhage) may be used. Recurrent or refractory bleeding may lead to need for surgery, although this has become uncommon as a result of improved endoscopic and medical treatment.

Join Dr. Emily Ko, a gynecologic oncologist at Penn Medicine, to learn about the latest updates from the Society of Gynecologic Oncology (SGO) 2024 Annual Meeting on Women’s Cancer. Dr. Ko will discuss what the research presented at the conference means for you and answer your questions about the new developments.
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

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
Anti ulcer drugs and their Advance pharmacology ||
Anti-ulcer drugs are medications used to prevent and treat ulcers in the stomach and upper part of the small intestine (duodenal ulcers). These ulcers are often caused by an imbalance between stomach acid and the mucosal lining, which protects the stomach lining.
||Scope: Overview of various classes of anti-ulcer drugs, their mechanisms of action, indications, side effects, and clinical considerations.

2. Upper GI bleed presents with
hematemesis
Hematemesis means vomiting of blood
The appearance of hematemesis
resembles coffee grounds
It indicates bleeding from upper GI
usually from esophagus, stomach and
duodenum above ligament of treitz
Conditions which cause hematemesis can
also cause melena
4. Peptic ulcer
It means ulcers in those parts of the gut
which are exposed to acid.
Common sites are duodenum , stomach and
can also occur in lower esophagus.
Causes:
Increase acid secretion(duodenal ulcer)
Decrease mucosal resistance(gastric ulcer)
NSAIDs ingestion
H.Pylori infection
Zollinger Ellison syndrome (uncommon)
5. Peptic ulcer pain is felt in the epigastrium and is well
localized. Patient points with one finger to the site of
pain- the ‘pointing sign’-
Duodenal ulcer
Occurs in the 1st part of duodenum.
Symptoms include
Pain epigastrium aggravated by empty
stomach(hunger pain), relieved by food and antacids
Nocturnal pains occur
Pain in the morning is not due to peptic ulcer
History of periodicity may be present.
