Theme:Early and Comparative diagnosis of diseases with the syndrome of fever TASHKENT MEDICAL ACADEMY Infectious and children infectious diseases department Lecturer:
What is fever ? • FEVER is a Diagnostic Clue • It is an essential host defense mechanism • Associated with or without localizing signs • It can be due toInfection, inflammation or neoplasm
Fever - Magnitude • Below 97 degree F – Hypothermia • 98.4 degree F - Normal • 98 to 102 degree F – INFECTIONS • 106 degree and above – Non- infectious fever (Hyperpyrexia)
Fever- Patterns • Intermittent type – temp return to normal once during most days • Remittent type – temp do not return to normal each day • Sustained/Continuous– temp do not vary more than 1 degree F /day • Relapsing - recurrent over days to weeks
Classical PUO • FEVER – MORE THAN 101 F • MORE THAN 3 WEEKS • CAUSE NOT DIAGNOSED AFTER ONE WEEK OF INTENSIVE HOSP INVESTIGN TYPES OF PUO • ACUTE, • NOSOCOMIAL, • HIV ASSOCIATED • NEUTROPENIC PUO
PUO – causes • INFECTIONS – 30% • MALIGNANCY –20% • CONNECTIVE TISSUE D- 15 % • OTHERS – 20 % • UNDIAGNOSED – 15 %
FEVER - Common Clues • RESPIRATORY SYMPTOMS – URTI ,LRTI,TB, • URINARY SYMPTOMS – UTI,APN,CYSTITIS • ABDOMINAL SYMPTOMS – ABSCESS,ACUTE ABDOMEN • ARTHRITIS SYMPTOMS –RA,SLE,AS • TRAVEL HISTORY • DIETARY HISTORY • OCCUPATIONAL HISTORY
TRAVEL History • MALARIA – ENDEMIC AREAS • DENGUE FEVER - Eg )SINGAPORE • VIRAL FEVERS • TYPHOID • TUBERCULOSIS • SCHISTOSOMIASIS
Dietary & Occupational History • BIRDS – PSITTACOSIS • ANIMALS CONTACT-TOXOPLASMOSIS (CAT), BRUCELLOSIS,LEPTOSPIROSIS (RAT) • UNCOOKED MEAT/SEA FOOD/ -HEPATITIS –A & E,SALMONELLA • UNPASTEURIZED MILK – SALMONELLA,TB,BRUCELLOSIS
Drug fever • All drugs can produce Drug INDUCED fever except DIGOXIN • Bradycardia, hypotension, Skin rash, pruritus +, • Eosinophilia • eg) pencillin, sulpha, ATT
THERE IS NO SUBSTITUTE FOR OBSERVING THE PATIENT, TALKING TO HIM AND THINKING ABOUT HIM.
FEVER & MYALGIA • VIRAL FEVERS – LEUCO & THROMBO CYTOPENIA • INFLUENZA – URTI SYMPTOMS • POLYMYOSITIS – PROXIMAL M WEAKNESS, MUSCLE PAIN & TENDERNESS, CPK HIGH • MENINGOCOCCAL INFECTION -Rash • SEPSIS
