CONTENT INTRODUCTION : DIAGNOSIS DIAGNOSIS METHODS ACCORDING TO CONVENTIONAL MEDICINE LAB INVESTIGATIONS RADIOLOGICAL INVESTIGATIONS
ORIGIN OF TERM DIAGNOSIS The word is derived through Latin from Greek word :
INTRODUCTION Diagnosis is a part of internal medicine A s we all, know “ internal medicine is medical speciality dealing with the prevention, diagnosis & treatment of adult diseases”.
MEANING OF MEDICAL DIAGNOSIS DEFINITION - Identification of a disease on objective (measurable) & subjective (non-measurable) symptoms.
APPROACH TO PATIENT
FUNDAMENTAL OF DIAGNOSIS DIAGNOSIS : Identification of a disease by investigation of its signs and symptoms. IDENTIFICATION Inquiry Physical examination Laboratory tests/Special examination ANALYSIS Basic knowledge of medicine Overall analysis Scientific way of clinical thinking
CLASSIFICATION OF DIAGNOSIS IN MEDICINE
1.MOLECULAR DIAGNOSIS
CONT. Molecular Diagnosis is a collection of techniques used to analyse biological markers in the individual genetic code[genome & proteome] & how their cells express their genes as proteins. Used to diagnose & monitor diseases, detects risk & decide which therapies will works best for the individual patient. Useful in range of med. Specialism,including -infectious diseases, oncology, pharmacogenomics –the genetic prediction of which drugs will work the best.
1.MEDICAL DIAGNOSIS( Process of determining ,which disease or condition explains a person’s symptoms & signs. Information required for diagnosis is typically collected from a history of patient & physical examination. It is often challenging because many signs & symptoms are non-specific . Eg-redness of skin (erythema) by itself is a sign of disorder & thus doesn’t tell the health care professional the exact cause .
HISTORY OF MEDICAL DIAGNOSIS First recorded examples are of Imhotep in ancient Egypt. Empiricism, logic & rationality in diagnosis of a disease was introduced by Esagil-kin-apli in Babylon medical textbook i.e. Diagnostic Handbook Huang di nei jing described 4 diagnostic methods which are used in TCM till now they are- Inspection, auscultation- olfaction, interrogation & palpation. Father of medicine, Hippocrates was known to make diagnosis by evaluating his patient’s urine & sweat.
MEDICAL USES Diagnosis is an attempt at classification of an individual’s condition into separate & distinct categories that allow medical decision about treatment & prognosis to be made. It is often described in terms of disease & other condition . Diagnostic procedure does not necessarily involve elucidation of etiology (cause) of the diseases. Diagnosis is initial task to detect a medical indications.
CONT. INDICATIONS INCLUDES: Detection of any deviation from normal For eg- anatomically (structure of body) Physiologically (how body works) Psychologically (thought & behaviour) Knowledge of what is normal & measuring of patients current condition against those norms.
DIAGNOSTIC CRITERIA The term designates the specific combination of signs ,symptoms & test results that physician uses to attempt to determine the correct diagnosis. And accordingly treatment should be given.
POSSIBLE ADVERSE EFFECTS OVERDIAGNOSIS Diagnosis of diseases that will never cause symptoms. It is a major problem because it turns people into patient. Lead to economic waste (overutilisation) & treatments that may cause harm.
II.ERRORS According to 2015 report of “ NATIONAL ACADEMIES OF SCIENCES,ENGINEERING & MEDICINE’’: M ost of the people experiences atleast 1 diagnostic errors in their life time . Causes & factors of errors: Manifestation of disease are not suffciently noticeable. Disease is omitted from consideration.
CONT. 3. Too much significance is given to some aspect of the diagnosis. 4.Rare diseases with symptoms suggestive of many other conditions. III . LAG TIME It is a delay time until a step towards diagnosis of disease or condition is made.
CONT. TYPES: 1.Onset to medical encounter lag time- The time from onset of symptoms until visiting a health care provider. 2.Encounter to diagnosis lag time -Time from first medical encounter to diagnosis.

HISTORY TAKING
INTRODUCTION Aim: At the end of the session students should know fundamentals of history taking and take a history of a simple disease Objectives: At the end of the session students should record: Chief complaint Present illness Past medical history Systemic enquiry Family history Drug history Social history
CHIEF COMPLAINTS The main reason push the point to seek for visiting a physician or for help. Usually a single symptoms, occasionally more than one complaints eg: chest pain, palpitation, shortness of breath, ankle swelling etc. The patient describe the problem in their own words . It should be recorded in points own words . What brings your here? How can I help you? What seems to be the problem?
CHIEF COMPLAINTS SHOULD BE: Short/specific in one clear sentence communicating present/major problem/issue. Timing – fever for last two weeks or since Monday Recurrent –recurring episode of abdominal pain/cough Any major disease important with PC e.g. DM, asthma, HT, pregnancy. Note: CC should be put in patient language.
PRESENT ILLNESS Elaborate on the chief complaint in detail Ask relevant associated symptoms Have differential diagnosis in mind Lead the conversation and thoughts Decide and weight the importance of minor complaints
PAIN{OPQRST} O nset of disease P osition/site Q uality, nature, character-burning sharp, stabbing, crushing & also explain depth of pain –superficial or deep R elationship to anything or other bodily functions /position R adiation-where moved to R elieving on aggravating factors –any activities or position
CONT. S everity –how it affects daily work/physical activities ; unable to sleep,unable to do any work T iming-mode of onset [abrupt/gradual] , progression[cont./intermittent; if intermittent ask frequency & nature] T reatment received or outcome
PAST MEDICAL HISTORY Start by asking the patient if they have any medical problems Heart Attack/DM/Asthma/HT/TB/Jaundice .E.g . if diabetic- mention time of diagnosis/current medication/clinic check up Past surgical/operation history E.g . time/place/ and what type of operation. Note any blood transfusion and blood grouping. History of trauma/accidents E.g . time/place/ and what type of accident
DRUG HISTORY Always use generic name or put trade name in brackets with dosage, timing and how long. Example: Ranitidine 150 mg BD PO Note: do not forget to mention OCP/Vitamins/Traditional medicine/KAP
DRUG HISTORY bd ( Bis in die) - Twice daily (usually morning and night) tds (ter die sumendus)/tid (ter in die) = Three times a day mainly 8 hourly qds (quarter die sumendus)/qid (quarter in die) = four times daily mainly 6 hourly Mane /(om – omni mane) = morning Nocte /(on – omni nocte) = night ac (ante cibum) = before food pc (post cibum) = after food po (per orum/os) = by mouth stat – statim = immediately as initial dose Rx (recipe) = treat with
SOCIAL HISTORY Smoking history - amount, duration and type. A strong risk factor for heart disease Drinking history - amount, duration and type. Cause cardiomyopathy, vasodilatation Occupation, social and education background , family social support and financial situation
OTHER RELEVANT HISTORY Gyanae/Obstetrics history [if female] Immunization if small child Travel and sexual history if suspected STD or infectious disease Note If small child, obtain the history from the care giver. Make sure; talk to right care giver . If some one does not talk to your language, get an interpreter(neutral not family friend or member also familiar with both language)ask simple & straight question but do not go for yes or no answer

SOAP Subjective : how patient feels/thinks about him. How does he look. Includes PC and general appearance/condition of patient Objective – relevant points of patient complaints/vital sings, physical examination/daily weight,fluid balance,diet/laboratory investigation and interpretation Assessment – address each active problem after making a problem list. Make differential diagnosis . Plan – about management, treatment, further investigation, follow up and rehabilitation
SYMPTOMS & SIGNS A symptom(complaint) is subjective feeling from the patient point of view . • A symptom is what the patient experiences about the disease . • Symptoms can only be experienced, they are not able to be observed or measured objectively . • Pain is a symptom. I do not know you are having pain unless you tell me. Nausea is also a symptom, as are: chills, numbness, fatigue, vertigo,malaise,itching,stomach cramps, burning on urination, etc.
CONT. Subjective sensation that patient describes Physiological & functional Pathological & morphological Fever Cough Rash Mass
CONT. A sign is an objective physical manifestation of disease. • It is an objective finding, something one can observe and measure . • A rapid pulse, a high temperature, a low blood pressure, an open wound, bruising, etc. are all signs . • Signs give a more definite indication of the presence of a particular disease to the physician . So in the simplest form, signs are observations of the doctor and symptoms are the experiences of the patient.
LAB INVESTIGATIONS
LAB/CLINICAL ANCILLARY TESTS Serum test Urine test B lood test stool test Sputum test Serous membrane fluid CSF test
LABORATORY TEST Laboratory tests check a sample of blood, urine, or body tissues. A technician or doctor analyses the test samples to see if results fall within the normal range. The tests use a range because what is normal differs from person to person. Many factors affect test results. These include:- Sex, age and race What to eat and drink Medicines How well the pre-test instructions are followed
CONT. It is often useful in comparing the results to results from previous tests. Laboratory tests are often part of a routine check-up to look for changes in the health. It also help doctors diagnose medical conditions, plan or evaluate treatments and monitor diseases.
A1C/GLYCOHEAMOGLOBIN/Hb A1C TEST It is used to test for type 2 diabetes & prediabetes It measures –Average blood glucose or blood sugar level over past 3 months This is often used to see how well one is managing diabetes It is different from blood sugar checks that people with diabetes do everyday
CONT. CLINICAL VALUES OF A1C TEST NORMAL VALUE= Below 5.7% PRE-DIABETES=B/W 5.7 -6.4% TYPE 2 DIABETES= Above 6.5% Done twice in a year for diabetic patients May need to retests every year for pre-diabetic patients
RECENT CLINICAL TRIALS [BY U.S. National institutes of Health] Designer functional foods on parameters of metabolic & vascular in pre-diabetes condition =pre-diabetes Interventions = dietary supplements:functional ingredient group, dietary supplements:conrol ingredients group
2.Effects of RBC survival on a commonly used diabetes lab test HbA1C Condition = diabetes mellitus,impaired fasting glucose, pre-diabetes Interventions = biological: re-infusion of biotin labelled cells, behavioural: diabetes education & medication adjustments.

PLATELET & AGING
HAEMOGLOBIN
HAEMOCRIT [Ht OR HCT] “ Packed cell volume (PCV)” or “Erythrocyte volume fraction (EVF)” It is the volume percentage (%) of RBC in blood. It is normally 45% for men and 40% for women.
MEAN CORPUSCULAR VOLUME It is average volume of a RBC. The normal range is : 80-100 fL An elevated MCV is termed as Macrocytic & is associated with : Alcoholism Folic acid deficiency Vit.

RENAL FUNCTION TEST Also known as “Kidney Function Test” Kidney function test is a collective term for a variety of individual tests and procedures that can be done to evaluate how well the kidneys are functioning.
RFT Can be divided into two categories: Test for function of Glomerulus GFR Test for Function of Tubule Reabsorption secretion
TEST INVOLVES IN RFT
RENAL CLEARANCE Renal clearance of a substance is the volume of plasma that is cleared of the substance by the kidneys per unit time . It is the measurement of the renal excretion ability Substances used for estimating kidney condition-INULIN ,CREATININE ,PAH
INULIN Inulin Clearance Can Be Used to Estimate GFR (eGFR) Inulin is : Freely filtered Neither reabsorbed Nor secreted Whatever, inulin is filtered, all of it is excreted in the urine.
INULIN EXCRETION
CREATININE Also known as- serum creatinine, urine creatinine Waste product in blood comes from protein [taken as food] & from the normal breakdown of muscles protein Elimination of it is done by kidney through urine Test can diagnose –creatinine level in blood which shows how well your kidneys are working
CREATININE Creatinine Clearance Can Be Used to Estimate GFR . It is not practical to measure urine creatinine level to estimate GFR, so many scientist has given many ways to calculate GFR by being based upon only blood creatinine.
eGFR Also, used to stage the Chronic Kidney Disease (CKD)
SERUM CREATININE(SCr) Normal range( Highly Variable ) - 0.5 to 1.0 mg/dl If, GFR < 50% normal, SCr will increase markedly But it is not an early marker of kidney disease
BLOOD UREA NITROGEN (BUN) The normal range is 6 - 20 mg/dL. Increased BUN Azotaemia Uraemia Azotaemia is used when the abnormality can be measured chemically but is not yet so severe as to produce symptoms. Uraemia is the pathological manifestations of severe azotaemia.
MECHANISM OF BUN
BUN BUN increased in: Renal failure Urinary tract obstruction Nephrotoxic drugs Shock, Burn, GI bleeding, Dehydration BUN is decreased in : Hepatic failure NS(normal saline) Cachexia (low-protein and high-carbohydrate diets)
BUN:CREATININE RATIO Normal Value= 12-20 The principle behind this ratio is the fact that both urea (BUN) and creatinine are freely filtered by the glomerulus, however urea reabsorbed by the tubules can be regulated (increased or decreased) whereas creatinine reabsorption remains the same (minimal reabsorption).
BUN: Cr RATIO IN KIDNEY INJURY
OTHER ORGAN FUNCTION TESTS LIVER FUNCTION TEST THYROID FUNCTION TEST KIDNEY FUNCTION TEST
LFT Helps to determine liver condition by measuring levels of Liver enzymes ,proteins, & bilirubin in blood Often used: To screen liver (hepatitis c) To monitor effects of medications To measure degree of liver cirrhosis
WHICH TEST MAKES LFT COMPLETE ALT(alanine transaminases) AST(aspartate transaminases) Albumin Bilirubin ALP(alkaline phosphatases)
ALBUMIN Protein made by liver Has important clinical value: Prevents fluid leakage from blood vessels nourishes tissues transports hormones, vitamin, minerals& other nutrient substances throughout the body albumin level decreased= impaired liver functioning
BILIRUBIN Waste product obtained by breakdown of RBC Increased level of bilirubin = impaired liver functioniong Normal range =Highly variable Normal adult = Total Bilirubin < 17µmol/L (1mg/dl) Out of which, around 30% is Direct bilirubin Normal Direct Bilirubin < 5.1µmol/L (0.3mg/dl)
HOW AST OR ALT INCREASES ?
ALT It is used up by your body to metabolise protein Liver damage = ALT released in blood Female ≤ 34 IU/L Male ≤ 52 IU/L Formerly known as serum glutamate-pyruvate transaminase (SGPT).
AST Type of enzyme found in several body parts such as liver, heart,& muscles Increased AST= liver infections Male 8 - 40 IU/L Female 6 - 34 IU/L Formerly known as serum glutamic oxaloacetic transaminase (SGOT).
AST/ALT RATIO Also known as "De Ritis Ratio" Specially used for alcoholic liver disease. It is AST to ALT ratio of 2:1 or greater, particularly with increased Gamma-Glutamyl Transferase.
LACTATE DEHYDROGENASE(LDH) Found in many body tissues, including the liver. Elevated levels of LDH may indicate liver damage. Elevated LDH maybe due to, Cancer Meningitis Encephalitis Acute pancreatitis HIV
ALKALINE PHOSPHATASE Found in bones, bile ducts,& liver Increased ALP = liver damage, blockage of bile duct & bone disorders
ALKALINE PHOSPHATASE Normal = 20 to 140 IU/L Although higher in children and pregnant Concomitant increases of ALP with GGT should raise the suspicion of hepatobiliary diseases
THYROID FUNCTION TEST
TFT : AN OVERVIEW Thyroid is a small gland located in lower front part of neck Helps to regulate – metabolism, energy generation, & mood It mainly produces 2 hormones: triiodothyronine(T3) & thyroxine (T4) TFT are series of blood test used to measure how well your thyroid gland is working Test includes-T3, T3RU, T4, & TSH
SECRETIONS As we all know secretions are of 2 forms – more or less i.e. hyper or hypo resp. According to secretion of hormones thyroid is of 2 types 1. hyperthyroidism 2.hypothyroidism
HYPER & HYPO ?? HYPERTHYROIDISM HYPOTHYROIDISM WEIGHT LOSS WEIGHT GAIN TREMORS LACK OF ENERGY INCREASED ANXIETY DEPRESSION
UNDERSTANDING RESULTS High levels of T4 = hyperthyroidism symptoms = anxiety, unplanned wt. less, tremors, diarrhoea TSH indicates = normal 0.4-4.0 m IU/L of blood if value ranges - above 2.0 mIU/L of blood T4 & TSH - routine performed on new-born babies to identify a low functioning thyroid gland which can lead to developmental abnormalities T3 RESIN UPTAKE RESULTS- measures hormone called thyroxine-binding globulin(TBG)
CONT. If T3↑ = TBG ↓ abnormal increase in TBG = kidney problems = body is not getting sufficient amount of protein ↑TBG = ↑ estrogen = pregnancy / obesity
TOTAL THYROXINE Total thyroxin includes free as well as protein bound thyroxin. Normal levels: 5 to 12.5ug/dL, largely bound to transport protein esp. TBG(Thyroid binding globulin ) T4 combined with TSH gives the best measurement of thyroid function.
ADVANTAGES OF THYROID SCANNING Distinguishes diffuse glandular activity from patchy pattern seen in goitre Functional classification of nodules: warm, hot, cold In association with thyroid suppression regimes, TSH dependent or autonomous nature of hot nodules Information regarding size, shape, position of gland Identification & localisation of functioning thyroid tissue in ectopic or metastatic sites Helps on differentiating various causes of thyrotoxicosis
INDICATIONS & CONTRAINDICATIONS INDICATIONS 1.Thyroid nodule(s) 2. Diffuse or multinodular goitre 3. Clinical hyper- or hypothyroidism 4. Evaluation of sub-sternal mass 5 . Sub-acute thyroiditis, early phase 6 . Patient with previously treated with radiation Contraindications: 1.Pregnancy 2.Lactation
FINE NEEDLE ASPIRATION CYTOLOGY (FNAC) THYROID Indications: Diagnosis of diffuse non toxic goitre Diagnosis of solitary or dominant thyroid nodule Confirmation of clinically obvious malignancy To obtain material for special laboratory investigations aimed at defining prognostic parameters. Main limitation : Inability to distinguish between follicular adenoma & carcinoma.
Complications: H aematoma . Transient laryngeal nerve paresis Tracheal puncture Rarely , needling causes formation of a hot nodule
CEREBRAL SPINAL FLUID
CSF Test to analyse condition which affects brain & spine CSF is the clear fluid which cushions & delivers nutrients to CNS (brain & spine) CSF is produced in the brain & then reabsorbed into blood stream CSF has a direct contact with our brain & spine therefore, it is more effective than a blood test to understand CNS Sample is collected by the method of LUMBAR PUNCTURE
CSF
LP[LUMBAR PUNCTURE] Also known as spinal tap Useful in examination for – proteins, glucose, RBC, fluid pressure, WBCs, chemicals, bacteria etc. Procedure to collect & look at the fluid(cerebrospinal fluid) surrounding the brain & spinal cord It should be performed only after a neurologic examination but should never delay
LP Most accurate test is culture. Most sensitive test for acute bacterial meningitis is elevation of protein in CSF . (Not elevated protein Rules out Acute bacterial meningitis) Increase in WBC is the indicator to start treatment.
INDICATIONS & CONTRAINDICATIONS INDICATIONS: Suspicion of meningitis Suspicion of subarachnoid haemorrhage(SAH) Suspicion of CNS , E.g.-carcinomatous meningitis Therapeutic relief of pseudotumor cerebri CONTRAINDICATIONS: Increased intra cranial pressure Brain abscess Loss of suprachiasmatic & basilar cisterns
WIDELY USED IN Multiple sclerosis is a chronic condition In this body’s own immune system destroys the protective coverings of nerves i.e. myelin Abnormal results in CSF is seen when there is: infections, encephalitis , Reye’s syndrome- rare fatal disease in children & is associated with viral infections & aspirin ingestion Scarcoidosis- granulomatous condition of unknown cause affecting many organs such as lungs, joints, & skin
SEROUS MEMBRANE FLUID Also known as serosa, is a layer of tissues that wraps around organs & helps to lubricate them so they don’t get rubbed raw. Made up of squamous epithelium or mesothelium
TRANSUDATE VS, EXUDATE Transudate It is extravascular fluid with low protein content and a low specific gravity (< 1.012 ) It results from increased fluid pressures or diminished colloid oncotic forces in the plasma. Exudate It is a fluid emitted by an organism through pores or a wound, a process known as exuding. Composition of an exudate varies, but generally includes water and the dissolved solutes of the main circulatory fluid such as sap or blood.

FACIAL DIAGNOSIS FATHER- LOUIS KUHNE IN MEDICAL TERMINOLOGY this art is known as physiognomy In this physician examines patient’s facial expressions & signs As chief function of face is expression, which is the giving of visible outer form/ manifestations of inner state of physical & mental being
FACIAL DIAGNOSIS As we all know face has following things to express: S pirit & countenance F orehead Temples Eyebrows Eyes Nose Glabella region Mouth & Lips
FACIAL DIAGNOSIS COUNTENANCE - traditional term for overall presentation of the face SPIRIT - radiates from countenance bright /radiant = overall healthy dull muddled/confused = mental & emotional

IRIS DIAGNOSIS FATHER - BERNARD JENSEN T hin, circular structure of the eye R esponsible for controlling diameter & size of pupil HOW IT WORKS: ACCORDING TO Dr. BERNARD JENSEN The iris is connected to every organ and tissue of the body by way of the brain and nervous system. The nerve fibers receive their impulses by way of their connections to the optic nerve, optic thalami and spinal cord They are formed embryologically from mesoderm and neuro-ectoderm tissues. Both sympathetic and parasympathic nervous systems are present in the iris
STUDY OF IRIS=IRIDOLOGY Nerve fibres in the iris respond to changes in body tissues by manifesting a reflex physiology that corresponds to specific tissue changes and locations IRIS CHART – chart represents the placement of organs and tissues as would a map. There are signs and features in the iris that are in-explainable and unknown at this time
IRIDOLOGY Iridology does not name diseases; instead, it reads tissue condition, From that information, predispositions, tendencies and directions toward or away from these conditions are noted. Levels of toxic settlement and accumulation are observable
