This presentation discusses hemorrhage, defined as the escape of blood from ruptured blood vessels causing a loss of blood. It classifies hemorrhage as either external/revealed, internal/concealed, or accidental. Major types are intracerebral and subaracnoid hemorrhage. Causes include wounds, fractures, accidents, bites, and anatomical defects. Signs are pallor, faintness, and thirst. Severe hemorrhage causes low blood pressure and air hunger. Effects include reduced cardiac output and vasoconstriction. External hemorrhage can be controlled through pressure, elevation, tourniquets, or coagulation methods. Special sites of hemorrhage have designated medical

Hemorrhage is a process of lose of blood either through a wound or because of any medical condition. Children are very prone to injuries as they are in the stage of attaining their motor developments.
The presentation deals with the basics of hemorrhage i.e. classification, etiology. It also covers the mechanism of hemostasis and the various methods to achieve hemostasis.
Hope you like it! Suggestions and feedback will always be well appreciated. :)

Orthodontics correction of malposed teeth
creates gingival contour s that are more conductive to
periodontal health .
Lower incisor may be extracted to correct crowding
,provided the extractions creates sufficient space for
proper alignment of the of the remaining teeth and
ad anterior guidance can be established in extensive
movements . in judicious extraction of mandibular
incisors although it corrects localized crowding ,may
result in an increase in the over jet and create
undesirable periodontal and aesthetic sequel
consultation with an orthodontist is recommended
before a lower incisor is extracted to eliminate
crowding

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

Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – 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 N0—N12, 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 N0—N12 (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.

Primary taste sensations: Sweet, Sour, Salty, Bitter, Umami
Chemical basis and signal transduction mechanisms for each taste
Taste Threshold and Index:
Taste threshold values for Sweet (sucrose), Salty (NaCl), Sour (HCl), and Bitter (Quinine)
Taste index relationship: Inversely proportional to taste threshold
Taste Blindness:

Supertasters:
25% of the population with heightened sensitivity to taste, especially bitterness
Increased number of fungiform papillae
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

2. HEMORRHAGE DEFINITION
• an escape of blood from a ruptured blood vessel.
OR
• loss of blood from the body as a result of injury or illness.
OR
• loss of blood from the vascular system associated with absolute reduction in the
circulating blood volume.
3. CLINICAL CLASSIFICATION OF HEMORRHAGE
1. revealed or external
2. concealed or internal
3. accidental hemorrhage
• accidental hemorrhage is of two types:
1. post-partum hemorrhage
2. hemorrhage due to premature detachment of placenta
5. TYPES OF HEMORRHAGE
Major two types:
1. intracerebral hemorrhage
2. subaracnoid hemorrhage
depending on time period after hemorrhage:
1. primary hemorrhage
2. reactionary hemorrhage
3. secondary hemorrhage
7. CAUSES OF HEMORRHAGE
• There are many causes of bleeding but
few and most commonest are:
1. WOUNDS
• A break in the continuity of skin, is known
as wound.Various types of wounds
include:
• incised wound
• lecaration
• abrasion
• contusion
• punctured and gunshot wound
10. SIGNS AND SYMPTOMS OF HEMORRHAGE
EARLY SIGNS AND SYMPTOMS:
• restlessness and anxiety
• feeling faint
• coldness
• pallor
• patient feel thirsty
11. SIGNS AND SYMPTOMS OF HEMORRHAGE
SIGNS AND SYMPTOMS AFTER
SEVERE HEMORRHAGE:
• extreme pallor
• air hunger
• extreme low blood pressure
• extreme thirst
12. EFFECTS OF HEMORRHAGE
• On cardiovascular system:reduced blood after hemorrhage decreases cardiac
output.
• during mild hemorrhage:blood pressure decreases slightly and soon it returns
to normal.
• during severe hemorrhage:the arterial blood pressure falls to a great extend.
13. EFFECTS OF HEMORRHAGE
on skin:
• vasoconstriction
• increases deoxygenation of blood
• results pallor in skin color.
on tisssue fluids:
• arterial constriction decreases capillary pressure.
• helps to compensate blood loss.
on kidney:
urinary output decreases.
14. CONTROL OF EXTERNAL HEMORRHAGE
1. pad and bandage
2. digital pressure
3. elevation of limb
4. application of tourniquet
5. surgical ligation
6. coagulation
7. pack
8. styptics
15. HEMORRHAGE SPECIAL SITES
occurance from special sites is designated by special terms:
• epistaxis
• hemoptysis
• haematemesis
• malaena
• hematuria
• haemothorax
• haemoperitonium
