3.) How to Diagnose Fungus Diseases.pptRashaAlNagar
Fungus diseases can be diagnosed through clinical clues, culture of the etiologic agent, and appearance in tissue. Clinical clues are often only suggestive. Culture of the agent is important to prove the etiology, with Sabouraud's medium most useful. Appearance in tissue can be seen through microscopy techniques like KOH examination, histopathology with stains like PAS, or GMS. The fungi may appear as yeasts, sporangia, hyphae, granules, sclerotic bodies, or a combination of yeast and hyphae depending on the disease. Definitive diagnosis relies on culture identification and correlating microscopic appearance in tissue.
Viruses are the smallest infectious agents that can only be seen using an electron microscope. They are obligatory intracellular parasites that contain either DNA or RNA, not both. Viruses are diagnosed through direct detection of the virus or its components using techniques like electron microscopy, immunoassays, and PCR. Indirect methods include serological diagnosis by detecting antibodies and skin tests. Viruses are cultivated inside living cells in tissue culture or laboratory animals since they cannot grow on artificial media.

Late submissions or submissions in incorrect formats like email or PDF will not be graded.
This document provides an overview of the syllabus for a course on medical mycology and virology. The course is divided into 6 units that cover topics such as the taxonomy and characteristics of medically important fungi, fungal infections like candidiasis and aspergillosis, classification of viruses, and techniques for viral diagnosis including PCR and DNA sequencing. The objectives of the course are for students to learn how to perform diagnostic tests to identify fungi. Learning outcomes include understanding the world of microbes like fungi and their adaptive strategies, as well as their economic and pathological importance.
The document discusses medical mycology, which is the study of pathogenic fungi that cause disease. It covers topics such as the classification of fungi, their modes of reproduction, pathogenesis of fungal infections, diagnosis of fungal diseases, and antifungal therapies. The major classes of antifungal drugs are discussed including polyenes, azoles, and echinocandins which act on the fungal cell membrane or cell wall.
The document discusses the human immune system and its defenses against pathogens. It describes how white blood cells such as phagocytes engulf and destroy bacteria and viruses. Antibodies produced by lymphocytes mark invading organisms for destruction. Vaccines work by exposing the body to weakened or dead forms of viruses and bacteria, causing it to develop immunity through the production of antibodies against those pathogens. The immune system provides multiple lines of defense that normally protect the human body from infection.
Isolation of bacteria is a significant step in diagnosing and managing bacterial infections. It involves collecting specimens, preserving and transporting them to the lab, examining samples microscopically, and using various culture and non-culture methods to isolate bacteria. Culture methods include using solid or liquid media, and automated systems, to allow bacterial colonies to grow. Non-culture methods involve molecular techniques like PCR. Proper specimen handling and use of appropriate culture conditions and media allow isolation of pathogenic bacteria to enable treatment and control of infections.
This document provides an overview of sputum examination, including indications, sample collection and transport, and various analysis methods. Physical examination can provide clues to underlying conditions. Microbiological examination includes gram stain to identify organisms, culture and sensitivity testing, and specialized staining techniques to identify acid-fast bacilli (AFB) like Mycobacterium tuberculosis. Molecular diagnostic methods like PCR can also detect pathogens. Cytological examination examines sputum for malignant cells and is most effective for centrally located lung cancers. A variety of specialized tests can identify other infectious organisms in sputum.
Viruses can infect humans and cause illness or death. Forensic virology studies viruses in a legal context, such as determining the source of a virus used in bioterrorism. Viruses have genetic material protected by a protein coat and sometimes an envelope. They infect cells and hijack the cell's machinery to replicate themselves before breaking out and infecting new cells. PCR and RAPD techniques can be used to detect, analyze, and trace viruses.

PGx Analysis in VarSeq: A User’s PerspectiveGolden Helix
Since our release of the PGx capabilities in VarSeq, we’ve had a few months to gather some insights from various use cases. Some users approach PGx workflows by means of array genotyping or what seems to be a growing trend of adding the star allele calling to the existing NGS pipeline for whole genome data. Luckily, both approaches are supported with the VarSeq software platform. The genotyping method being used will also dictate what the scope of the tertiary analysis will be. For example, are your PGx reports a standalone pipeline or would your lab’s goal be to handle a dual-purpose workflow and report on PGx + Diagnostic findings.
The purpose of this webcast is to:
Discuss and demonstrate the approaches with array and NGS genotyping methods for star allele calling to prep for downstream analysis.
Following genotyping, explore alternative tertiary workflow concepts in VarSeq to handle PGx reporting.
Moreover, we will include insights users will need to consider when validating their PGx workflow for all possible star alleles and options you have for automating your PGx analysis for large number of samples. Please join us for a session dedicated to the application of star allele genotyping and subsequent PGx workflows in our VarSeq software.

CLASSIFICATION OF H1 ANTIHISTAMINICS-
FIRST GENERATION ANTIHISTAMINICS-
1)HIGHLY SEDATIVE-DIPHENHYDRAMINE,DIMENHYDRINATE,PROMETHAZINE,HYDROXYZINE 2)MODERATELY SEDATIVE- PHENARIMINE,CYPROHEPTADINE, MECLIZINE,CINNARIZINE
3)MILD SEDATIVE-CHLORPHENIRAMINE,DEXCHLORPHENIRAMINE
TRIPROLIDINE,CLEMASTINE
SECOND GENERATION ANTIHISTAMINICS-FEXOFENADINE,
LORATADINE,DESLORATADINE,CETIRIZINE,LEVOCETIRIZINE,
AZELASTINE,MIZOLASTINE,EBASTINE,RUPATADINE. Mechanism of action of 2nd generation antihistaminics-
These drugs competitively antagonize actions of
histamine at the H1 receptors.
Pharmacological actions-
Antagonism of histamine-The H1 antagonists effectively block histamine induced bronchoconstriction, contraction of intestinal and other smooth muscle and triple response especially wheal, flare and itch. Constriction of larger blood vessel by histamine is also antagonized.
2) Antiallergic actions-Many manifestations of immediate hypersensitivity (type I reactions)are suppressed. Urticaria, itching and angioedema are well controlled.3) CNS action-The older antihistamines produce variable degree of CNS depression.But in case of 2nd gen antihistaminics there is less CNS depressant property as these cross BBB to significantly lesser extent.
4) Anticholinergic action- many H1 blockers
in addition antagonize muscarinic actions of ACh. BUT IN 2ND gen histaminics there is Higher H1 selectivitiy : no anticholinergic side effects

Breast cancer :Receptor (ER/PR/HER2 NEU) Discordance.pptxDr. Sumit KUMAR
Receptor Discordance in Breast Carcinoma During the Course of Life
Definition:
Receptor discordance refers to changes in the status of hormone receptors (estrogen receptor ERα, progesterone receptor PgR, and HER2) in breast cancer tumors over time or between primary and metastatic sites.
Causes:
Tumor Evolution:
Genetic and epigenetic changes during tumor progression can lead to alterations in receptor status.
Treatment Effects:
Therapies, especially endocrine and targeted therapies, can selectively pressure tumor cells, causing shifts in receptor expression.
Heterogeneity:
Inherent heterogeneity within the tumor can result in subpopulations of cells with different receptor statuses.
Impact on Treatment:
Therapeutic Resistance:
Loss of ERα or PgR can lead to resistance to endocrine therapies.
HER2 discordance affects the efficacy of HER2-targeted treatments.
Treatment Adjustment:
Regular reassessment of receptor status may be necessary to adjust treatment strategies appropriately.
Clinical Implications:
Prognosis:
Receptor discordance is often associated with a poorer prognosis.
Biopsies:
Obtaining biopsies from metastatic sites is crucial for accurate receptor status assessment and effective treatment planning.
Monitoring:
Continuous monitoring of receptor status throughout the disease course can guide personalized therapy adjustments.
Understanding and managing receptor discordance is essential for optimizing treatment outcomes and improving the prognosis for breast cancer patients.

Storyboard on Acne-Innovative Learning-M. pharm. (2nd sem.) CosmeticsMuskanShingari
Acne is a common skin condition that occurs when hair follicles become clogged with oil and dead skin cells. It typically manifests as pimples, blackheads, or whiteheads, often on the face, chest, shoulders, or back. Acne can range from mild to severe and may cause emotional distress and scarring in some cases.
**Causes:**
1. **Excess Oil Production:** Hormonal changes during adolescence or certain times in adulthood can increase sebum (oil) production, leading to clogged pores.
2. **Clogged Pores:** When dead skin cells and oil block hair follicles, bacteria (usually Propionibacterium acnes) can thrive, causing inflammation and acne lesions.
3. **Hormonal Factors:** Fluctuations in hormone levels, such as during puberty, menstrual cycles, pregnancy, or certain medical conditions, can contribute to acne.
4. **Genetics:** A family history of acne can increase the likelihood of developing the condition.
**Types of Acne:**
- **Whiteheads:** Closed plugged pores.
- **Blackheads:** Open plugged pores with a dark surface.
- **Papules:** Small red, tender bumps.
- **Pustules:** Pimples with pus at their tips.
- **Nodules:** Large, solid, painful lumps beneath the surface.
- **Cysts:** Painful, pus-filled lumps beneath the surface that can cause scarring.
**Treatment:**
Treatment depends on the severity and type of acne but may include:
- **Topical Treatments:** Such as benzoyl peroxide, salicylic acid, or retinoids to reduce bacteria and unclog pores.
- **Oral Medications:** Antibiotics or oral contraceptives for hormonal acne.
- **Procedures:** Such as chemical peels, extraction of comedones, or light therapy for more severe cases.
**Prevention and Management:**
- **Cleanse:** Regularly wash skin with a gentle cleanser.
- **Moisturize:** Use non-comedogenic moisturizers to keep skin hydrated without clogging pores.
- **Avoid Irritants:** Such as harsh cosmetics or excessive scrubbing.
- **Sun Protection:** Use sunscreen to prevent exacerbation of acne scars and inflammation.
Acne treatment can take time, and consistency in skincare routines and treatments is crucial. Consulting a dermatologist can help tailor a treatment plan that suits individual needs and reduces the risk of scarring or long-term skin damage.

Understanding Atherosclerosis Causes, Symptoms, Complications, and Preventionrealmbeats0
Definition: Atherosclerosis is a condition characterized by the buildup of plaques, which are made up of fat, cholesterol, calcium, and other substances, in the walls of arteries. Over time, these plaques harden and narrow the arteries, restricting blood flow.
Importance: This condition is a major contributor to cardiovascular diseases, including coronary artery disease, carotid artery disease, and peripheral artery disease. Understanding atherosclerosis is crucial for preventing these serious health issues.
Overview: We will cover the aims and objectives of this presentation, delve into the signs and symptoms of atherosclerosis, discuss its complications, and explore preventive measures and lifestyle changes that can mitigate risk.
Aim: To provide a detailed understanding of atherosclerosis, encompassing its pathophysiology, risk factors, clinical manifestations, and strategies for prevention and management.
Purpose: The primary purpose of this presentation is to raise awareness about atherosclerosis, highlight its impact on public health, and educate individuals on how they can reduce their risk through lifestyle changes and medical interventions.
Educational Goals:
Explain the pathophysiology of atherosclerosis, including the processes of plaque formation and arterial hardening.
Identify the risk factors associated with atherosclerosis, such as high cholesterol, hypertension, smoking, diabetes, and sedentary lifestyle.
Discuss the clinical signs and symptoms that may indicate the presence of atherosclerosis.
Highlight the potential complications arising from untreated atherosclerosis, including heart attack, stroke, and peripheral artery disease.
Provide practical advice on preventive measures, including dietary recommendations, exercise guidelines, and the importance of regular medical check-ups.
