1. The document discusses fundamental theorems of medical diagnosis, including three formulations of the theorems.
2. The first theorem states that no disorder exists without symptoms and no symptoms exist without a disorder. The second theorem states that a disorder can be transmitted between individuals.
3. Koch's postulates and an extended version by Fredericks and Relman are used to prove the second theorem by demonstrating disease transmission from one individual to another.

The Biopsychosocial Model 25 Years Later:
Principles, Practice, and Scientifi c Inquiry
ABSTRACT
The biopsychosocial model is both a philosophy of clinical care and a practical
clinical guide. Philosophically, it is a way of understanding how suffering, disease,
and illness are affected by multiple levels of organization, from the societal to the
molecular. At the practical level, it is a way of understanding the patient’s subjec-
tive experience as an essential contributor to accurate diagnosis, health outcomes,
and humane care. In this article, we defend the biopsychosocial model as a nec-
essary contribution to the scientifi c clinical method, while suggesting 3 clarifi ca-
tions: (1) the relationship between mental and physical aspects of health is com-
plex—subjective experience depends on but is not reducible to laws of physiology;
(2) models of circular causality must be tempered by linear approximations when
considering treatment options; and (3) promoting a more participatory clinician-
patient relationship is in keeping with current Western cultural tendencies, but may
not be universally accepted. We propose a biopsychosocial-oriented clinical prac-
tice whose pillars include (1) self-awareness; (2) active cultivation of trust; (3) an
emotional style characterized by empathic curiosity; (4) self-calibration as a way to
reduce bias; (5) educating the emotions to assist with diagnosis and forming thera-
peutic relationships; (6) using informed intuition; and (7) communicating clinical
evidence to foster dialogue, not just the mechanical application of protocol. In con-
clusion, the value of the biopsychosocial model has not been in the discovery of
new scientifi c laws, as the term “new paradigm” would suggest, but rather in guid-
ing parsimonious application of medical knowledge to the needs of each patient.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

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

Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

2. Overview
• Fundamental theorems of medical
diagnosis: Various formulations
• Koch postulates
• Fredericks & Relman extended version
theorem
• Proof of the second theorem.
• The importance of Koch's famous
postulates to disease transmission.
3. General definitions
Fundamental theorems originate from theorems of war and mental disorders that describe human unhealthiness
which triggers the precipitation of distressed conditions (Ayim-Aboagye et al. 2018). The disease stricken
person voluntarily seeks help from a competent practitioner (i.e., trained through several years of apprenticeship
in medicine). Here, the inequality which steers the fruitful relationship is described and portrayed vividly. With
(<), the patient is portrayed as being in a subservient position in the distressed condition in relation to the
practitioner S who is strong and healthy, and with (>), the latter is shown to be possessing exceeding knowledge
encompassing the patient providing us the inequality of conditions Qₔ < S > Q. This is synonymous to
professional security that is guaranteed and ultimately given to Qₔ in his distressed condition. Zero-point
condition (Zҫ) signifies the state of being in absolute distressed, petrified, and non-equilibrium. This state is
closer to the death state (ƫҫ) which is equal to the state of negation (Nҫ). So (ƫҫ = Nҫ) in the phenomenon of
medical diagnosis. A patient's restoration to 'health–generated–wellness' by the practitioner is called
equilibrium–point condition (Eҫ). Thus zero-point (Zҫ) is defined as "Qₔ is in a subservient condition of S if Qₔ
< S for all Qₔ ɛ N." The equilibrium-point condition (Eҫ) thus becomes "S is more knowledgeable over Qₔ if S >
Qₔ for all S ɛ N." With this, we can also add the concept of time (t) in the rationalization accompanying the
onset of any disease/illness.
4. First Formulation
• Theorem 1: No disorder is without a symptom; vice
versa no symptom is without a disorder.
• Theorem 2: A disorder can be transmitted from one
individual to one another.
• Theorem 3: An Individual patient disorder cannot be
treated in isolation by the patient; it must be attended to
by experts through voluntary consultation that has been
made by the patient.
5. Second Formulation
• 1. If a patient is diagnosed as possessing a specific disorder, then
there is a corresponding symptom(s) on which the practitioner has
based his competent decisions/predictions.
• 2. In cases where a disorder is judged to be an infectious disease or
violent personality disorder, then there is the greater likelihood that
a patient can transmit this disorder to other individuals irrespective
of who comes into contact with him/her.
• 3. A diagnostic procedure involving a disorder is not handled in
isolation by a patient; it is attended to and steered by a competent
practitioner who confronts a distressed patient that has voluntarily
sought help
6. Third Formulation: Mathematical
• 1.If an individual Q is diagnosed as having a disorder D, then there
is a corresponding symptom C which is known as lurking behind D;
then Qₔ = C ≅ D and the vice versa is also true Qₔ = D ≅C. Where ₔ
represents the condition of Q.
• 2.Suppose that Qₔ were to be the distressed patient in a zero-point
condition (Zҫ) who is distressed, petrified, and disequilibrium, then
the following (could result) patients can contract the illness from
{Qₔ → Qₔ1 → Qₔ 2 → Qₔ 3 → … Qₔ N}. The formula then becomes
Zҫ = Qₔ → Qₔ1 → Qₔ 2 → Qₔ 3 → … Qₔ N.
• 3.Let Q be in the zero-point condition (Zҫ) of illness Qₔ that is
distressed, petrified, and disequilibrium. For every zero-point
condition Qₔ < S > Q. Then, the following inequalities hold at any
zero-point condition: Zҫ = Qₔ < S > Q. This means Qₔ is subservient
to S, the practitioner that is more knowledgeable than Q in the
encompassing powerful context of medical diagnosis.
7. THE TRIAD OF DIAGNOSTIC
RELATIONS
These theorems can help physicians to
comprehend:
• Firstly, disorder- symptom relation;
• Secondly, disorder transmission relation (Here,
Koch postulates and its reformulation by
Fredericks and Relman (1996) could be used to
prove this theorem);
• Thirdly, practitioner-patient relation.
8. Theorem 1.
• If an individual Q is diagnosed as having a
disorder D, then there is a corresponding
symptom C which is known as lurking
behind D; then Qₔ = C ≅ D and the vice
versa is also true Qₔ = D ≅C.
• Where ₔ represents the condition of Q.
9. Proof referring to theorem one
• Referring to theorem one, since it is
acknowledged that every disorder has a
symptom upon which it could lead the
competent practitioner to the root cause of the
patient's dire situation, and vice versa every
symptom has a lurking disorder/points to a
disorder at every zero-point condition (Zҫ), the
theorem is said to be obvious. Thus it says that
Qₔ = C ≅ D and the vice versa is also true Qₔ =
D ≅C. Furthermore, the zero-point condition is
the originating point of all true conditions of
disease /illness when patients need
cure/treatment.
10. Remarks on theorem one
• The proof of the theorem as an obvious one is
not to be disputed. It can, therefore, be
remarked that when we discuss or engage in the
commencement of every diagnosis, we most
often focus on the first fundamental theorem.
11. Proof of Existence of Second
Fundamental Theorem
• Preamble:
Let us now introduce the second fundamental theorem
again: A disorder can be transmitted from one individual to
one another. Alternative propositions:
In cases where a disorder is judged to be an infectious
disease or violent personality disorder, then there is the
greater likelihood that a patient can transmit this disorder
to other individuals irrespective of who comes into contact
with him/her.
12. Theorem 2.
• Suppose that Qₔ were to be the distressed
patient in a zero-point condition (Zҫ) who
is distressed, petrified, and disequilibrium,
then the following (could result) patients
can contract the illness from {Qₔ → Qₔ1
→ Qₔ 2 → Qₔ 3 → … Qₔ N}. The formula
then becomes Zҫ = Qₔ → Qₔ1 → Qₔ 2 →
Qₔ 3 → … Qₔ N.
13. Remarks about the attempt to
prove the second theorem
• While the first theorem is obvious and needs no proof,
because it is agreed that every disorder has a symptom
and also that every symptom portrays the signal of a
major or minor lurking disorder, according to our
understanding, the second fundamental theorem could
easily be proved with Koch postulates (Koch, 1893:319-
38). Yet, additional proof/illumination could also be
gained from the use of what I call the Fredericks and
Relman (1996: 18-33) extension theorem of Koch
postulates.
14. Proof: Hermann Koch and his
Famous Scientific Postulates
Koch's postulates :
• 1. The microorganism must be found in abundance in all
organisms suffering from the disease, but should not be
found in healthy organisms;
• 2. The microorganism must be isolated from a diseased
organism and grown in pure culture;
• 3. The cultured microorganism should cause disease
when introduced into a healthy organism;
• 4. The microorganism must be isolated again from the
inoculated, diseased experimental host and identified as
being identical to the original specific causative agent
(Koch, 1876: 277–310).

infectious diseases (2) Identified causative agents of anthrax and tuberculosis –

18. Alternative Proof Using Fredericks and
Relman Extended Version Theorem
• The following conditions (Fredericks and Relman, 1996:18-33), also satisfy the second
fundamental theorem:
(a) A nucleic acid sequence belonging to a putative pathogen should be present in most cases of
an infectious disease. Microbial nucleic acids should be found preferentially in those organs or
gross anatomic sites known to be diseased, and not in those organs that lack pathology.
(b) Fewer or no copies of pathogen-associated nucleic acid sequences should occur in hosts or
tissues without the disease.
(c) With the resolution of disease, the copy number of pathogen-associated nucleic acid sequences
should decrease or become undetectable. With clinical relapse, the opposite should occur.
(d) When sequence detection predates disease or sequence copy number correlates with the
severity of disease or pathology, the sequence-disease association is more likely to be a causal
relationship.
(e) The nature of the microorganism inferred from the available sequence should be consistent
with the known biological characteristics of that group of organisms.
(f) Tissue-sequence correlates should be sought at the cellular level: efforts should be made to
demonstrate specific in situ hybridization of microbial sequence to areas of tissue pathology
and visible microorganisms or to areas where microorganisms are presumed to be located.
(g) These sequence-based forms of evidence for microbial causation should be reproducible.

Koch's postulates.

21. Inference
• Since the second theorem of the fundamental theorems of medical
diagnosis states that a disorder can be transmitted from an
individual to another individual and this is well exemplified in
hospital environments as well as general controlled environment
through research, we infer from Koch postulates and Fredericks and
Relman's extended version theorem that a disorder is transmittable
to individuals/organisms in all conditions as explained (whether it is
in the laboratory or the field). Hence there is an illness or disease
transmission principle that is enshrined in the fundamental concepts
of medical diagnosis. Moreover, there exists a disorder transmission
principle which the second theorem postulates.
22. Concluding Remarks
• Fundamental theorems of medical diagnosis are the
results in a medical theory involving disorders which
establish the existence of a common genesis of zero-
point condition illness or disease etiology. The theorems
are ingredients in several other important results,
notable among which are proofs that a disorder can be
transmitted from one person to another person.
Therefore, it signifies that there exists a disorder
transmission principle that the second theorem in
particular postulates on.
