Trauma and stressor-related disorders are a group of emotional and behavioral problems that may result from childhood traumatic and stressful experiences. These traumatic and stressful experiences can include exposure to physical or emotional violence or pain, including abuse, neglect or family conflict.
PTSD is a disease first introduced into the diagnostic and statistical manual of mental disorders (DSM) in 1980
With the world experiencing an unprecedented onslaught of disasters and traumas, it is imperative that health workers are aware of the disease and the factors that affect it
Chapter Seven:
Posttraumatic Stress Disorder
Background of PTSD
Psychic trauma is the result of experiencing an acute overwhelming threat in which disequilibrium occurs.
Most people are extremely resilient and will quickly return to a state of mental and physical homeostasis.
Acute stress disorder is when symptoms continue for a period of 2 days to 1 month and have an onset within 1 month of the traumatic event.
Background Cont.
If acute stress disorder symptoms develop, they will typically diminish in 1 to 3 months.
Delayed PTSD is when symptoms disappear for a period of time and then reemerge in a variety of symptomatic forms months or years after the event.
Benchmarks

The problem based learning was developed in the university of McMaster, Canada, in 1976.
It emphasizes on the problem as the starting point for the acquisition and integration of new knowledge. This enables the students to earn critical thinking and problem solving skills, which are essential to nursing practice.

Family therapy is a family oriented psychotherapy that is aomed at resolving the conflicts and poor communication pattern among the family members. It also aid them in learning coping strategies to deal with distress and deal with the stress related to psychiatric illness of the family member.
Cognitive behaviour therapy is a talk (psychotherapy) therapy wherein the therapist focus on modifying or altering the faulty cognitions in an individual in order to treat the symptoms of mental illness
Individual psychotherapy is a one to one therapy wherein the therapist identifies the root cause of symptoms that are hidden in the subconsciousness by using the principles of psychoanalysis. The client is helped to gain insight about these represeed thoughts and feelings and thus acquiring better resolution of the mental conflicts
Psychodynamic psychotherapy also known as psychoanalytic therapy is based on psychoanalysis and psychoanalytic theory given by Sigmund Freud. Psychodynamic therapy identifies the relation between Id, ego and superego and its impact on human behavior. It helps a person to resolve the conflicts stored in subconscious mind by making them conscious
Psychoanalysis was given by Sigmund freud to analyse the subconscious mind and its impact on present behavior. Psychoanalysis is the core concept of psychotherapies that aims to make the unconscious thoughts and emotions concious

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.
Bowmanâs 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
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
Itâs 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

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years â 64.8%, 20 years â 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP â more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0âN12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0âN12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
