What in medical history do we need to consider when it comes to respiratory system and cardiovascular?Respiratory system: Cough Dyspnoe Pain in chest Apnoe Hematoptysis Cyanosis Cardiovascular system: Dyspnoe Oedemas Cyanosis
What do we need to consider during physical examination when it comes to respiratory and cardiovascular system?Respiratory system: Tachypnoe/bradypnoe Dyspnoe Cyanosis Patologic sounds upon auscultation Abnormalities on auscultation Cardiovascular system: Tachycardia /bradycardiaMurmurs Arrhytmias Abnormal apex beat
What is cough?Cough- sudden expulsion of air -protective reflexphysiologically removing particles from airway , incidental cough- normal phenomenon • Recurent coughing- sign of disease • Most frequently manifestation of upper or lower respiratory airways
What 3 types of cough do we have?Dry cough- usually upper respiratory tract infections • Productive cough-usually lower respiratory tract infection( bronchitis, pneumonia) • Acute caugh( <3 weeks, usually infections), persistent( 3- 8 weeks), chronic ( >8weeks)
Causes of acute cough• Infections • Asthma • Choking • Forein body in airways • Pneumothorax
Causes of chronic cough• Cystic fibrosis • Gastro-esophageal reflux • Tuberculosis • Bronchiectases( CF, immune deficiencies) • Impression on airways( tumor-lymphoma, vascular ring) • Foreign body in Airways • Reccurent aspiration due to oesophago-tracheal fistula• Chronic interstitial lung diseases • Chronic sinusitis
Signs of dyspnoea:-use of accessory respiratory muscles, -nasal flaring, -grunting, -subcostal retraction - excessive movements of diaphragm Abnormal respiratory rate( bradypnoe, tachypnoe) may accompany dyspnoea
Most frequent causes of dyspnoe- respiratory system diseasesRespiratory dyspnoea • Inspiratory: upper airway( throat,larynx, trachea) • Expiratory : lower airway- bronchi • Mixed dyspnoea: alveoli
Types of dyspnoeaRespiratory dyspnea – due to respiratory tract pathology, • Cardiac dyspnea – cardiac failure • Metabolic dyspnea – usually due to acidosis • Anaemic dyspnea – due to dysfunction or low number of red blood cells • Neurognic dyspnea – secondary to neurologic system impairmen • Inspiratory dyspnea – laryngitis, larynospasm, laryngeal oedema ( anaphylaxis), foreign body in larynx • Expiratory dyspnea- asthma, wheezy bronchitis, bronchiolitis • Mixed dyspnea- pneumonia, pleuritis, pneumothorax
Pain in chest, what is it and what causes it?Contrary to adults, children most often suffer from non-cardiac causes of chest pain (e.g. a heart attack practically does not occur in children). Causes • Pleuritis • Emphysema • Pulmonary embolism • Myocarditis • Pericarditis • Acute pancreatitis • Psychogenic causes (after exclusion of organic causes !!!)
Apnoe, what is it and what causes it?Blockage of airflow in respiratory tract Causes • Hypertrophy of tonsils • Decreased muscle tone • Obesity • May appear also in healthy individuals Affective apnea- preceded by strong emotions
What types of apnoe do we have?• Central- immaturity of medullar respiratory centre, decreased sensitivity to hypercapnia, mainly in premature infants • Obstructive- obstruction of upper respiratory airways, non-efectiverespiratory movements, obstructive sleep apnoea is an indication for laryngologic consutation
HemoptysisRare symptom in children Mostly originate from throat/nose • Nasophrygeal infection • tonsilitis From lower respiratory tract • bronchiectases ( cystic fibrosis, immune deficiencies) • pulmonary abscess • tuberculosis • vasculitis
What is cyanosis and what types do we have?Definition- bluish discoloration, especially of the skin and mucous membranes, due to excessive concentration of deoxygenated hemoglobin in capilary blood -> 5 g/dl Cyanosis classification • Central- decreased saturation of oxegen saturation of hemoglobin in arterial blood, predominantly visible on lips, tongue and oral cavity. • Peripheral- decreased perfusion of periphery, visible on peripheral parts of body
What dieses can cyanosis be a symptom of in respiratory and cardiovascular systems?Diseases of respiratory tract( respiratory failure) • Foreign body of trachea, larynx • Choanal atresia • Epiglottitis • Bronchiolitis • Severe asthma attack • End stage of cystic fibrosis Diseases of cardiovascular system • Cyanotic cardiac defect (ie. Falot syndrome) • Cardiogenic shock • In all the mentioned condiotions exept cardiogenic shock central cyanosis
Tachypnoe/bradypnoe• Abnormal( too high/too law respiratory ratein relations to age Normal respiratory rate • newborn 40-60/min • infant 30-50/min • 1-5 years 26-40/min • 6-8 years 18-30/min • older 14-20/min • Most frequently accompanies dyspnoe
Auscultation abnormalities over lungs- pathologic soundsRhonci and wheezes- come from bronchi as a result of their obturation due to oedema and mucus overproduction, usually present on expiration Crepitations, crackles – audible when air comes back into atelectatic vessicles (atelectasis, inflammation) best heard at the top of inspiration, typical for pneumonia Pleural friction- best heard at the end of inspiration and the beginning of expiration in pleuritis without exudate.
Auscultation abnormalities over lungs- pathologic sounds 2Patologic bronchial sound if present over lungs, not in the typical location- lobar pneumonia • Prolonged expiration- obstruction of bronchi , wheezy bronchitis, bronchiolitis • Prolonged inspiration – narrowing of larynx, laryngitis
Percussion abnormalities• Dull pecussion sound –presence of fluid in pleura ( pleuritis) airless fragment of lung( atelectasis), diffuse pneumonia ( loban pneumonia) • Hyperresonant sound – emphysema • Tympanic sound - pneumothorax
Vocal fremitus abnormalitiesAbsent or decreased- pnaumothorax, presence of fluid in pleural cavity Increased- over an airless part of lung- lobar pneumonia
Tachycardia• Heart rate above the normal range in relation to age. May be physiologically present. In many pathologies. Compensative mechanism • 1 month – 100-180 • 2-6 month – 100-140 •6-12 month – 100-120 •2-6 years – 90-110 •7-10 years – 80-100 •11-14 years – 70-90
What types of tachycardia do we have?Sinusal • fever, stress, anxiety • hipotension • anaemia • conditions presenting with hypoxia, respiratory failure • severe infections • hyperthyroidism, • cardiac failure, medications/stimulants • dehydration, shock Extra sinusal- cardiologic diseases
Bradycardia• Bradycardia- heart rate lower than norm in relation to age The most common causes • Apnoe and bradycardia of premature infants • Arrhytmias and conduction disturbances • Increased intracranial pressure • Medications
ArrhythmiaRespiratory arrhythmia- physiologic in children, increasedheart rate on inspiration, dissapaers , when a child stops to breathe Arhythmias- cardiologic diseases
How do we divide cardiac murmurs?Cardiac ( systolic, diastolic, systo-diastolic ) • Organic causes - cardiac defects • Functional – cardiac enlargment, hyperkinetic circulation • Innocent murmurs Extracardiac (pericardial friction)
Characteristics of innocent murmurs• Loudness 1-3/6 Levine’s scale • Without any heart failure. • Proper development • Mainly systolic • Position dependent
Apex beat abnormalitiesDiffuse,high, abnormally located: cardiac defects, cardiac failure,cardiomyopathies
Skin colour abnormalites- Palor • Redness • Icterus • Cyanosis
Causes of palorAnaemia- palor best visible on lips, auricles, conjunctiva • Infections • Dehydration • Low blood pressure- syncope • Shock
Causes of rednessFever • Overheating • Carbon monoxide intoxication • Neonates in first days of life- skin physiologically redpolicytemia • Local redness for example over inflammed lymphnode or joint
Causes of icterusThe most common causes !!!! • Physiologic jaundice in 60% !!!! of full term neonates • Breast milk jaundice Blood and liver diseases as causes of jaundice will be discussed next year
Patomechanisms of physiologic jaundiceImmaturity of the liver- decreased conjugation with glucuronic acid • Increased destruction of erythrocytes( presence of fetal hemoglobin,) • Increased enterohepatic circulation of bilirubin
Criteria of physiologic jaundice• Unconjugated bilirubin • Not in the first day of life • Not longer than 10 days ( ful term newborns),14 days premature neonates • Level lower than 15 mg% (artificial feeding) i 17 mg% ( brest feeding) • The daily increase lower than 5 mg% , less than 0,3 mg% per hour • No pathologic symptoms present
Breast milk jaundicecomponents of breast milk hinder bilirubin conjugation • early ( 2-3 day) late(7 day) • unconjugated bilirubin • therapeutic-diagnostic trial- the decrease in bilirubin level after stopping breast feeding for 24-48 h or feedingwith previusly heated breast milk • needs to be differentiated with pathologic jaundices
oedema patomechanism• Decreased oncotic pressure : (hypoalbuminemia) • Increase blood vessels permeability • Venous stasis • Lymph stasis
Main causes of oedemasCardiac failure • Renal failure • Liver failure • Nephrotic syndrome • Allergy
Primary skin lesionsmacule • papule • vesicle • blister • pustule • wheal • nodule
Secondary skin leasions• crust • erosion • scale • lichenication • scar • excoriation
Maculemost common category erythematous due to blood vessels dilatation upon pressing dissapear if its macular rash upon pressing do not dissapear if its hemorrhagic rash - fever and measles - allergic rash allergy to drugs - in Schoenlein Henoch disease - hemorrhagic rash in meningococcal sepsis - cafe au lait
Papule- diper dermititis
Vesiclechickenpox (vesicular rash) wheal
Pustuleacne
Lichenicationatopic dermatitis
Excoriationsatopic dermititis
Scaleseborrhoic dermatitis
During the examination of lymph nodes the following elements have to be assessedsize location number single/cluster consistency- hard, soft, firm mobile/fixed Tenderness appearence of the skin over lymphnode: normal/inflammed
The following groups of lymph nodes have to be palpated• occipital • retroauricular • nuchal • preauricular • cervical • submadibular • axilar • supraclavicular • inguinal
Lymphadenopathy, the most important causesLymphadenitis- painful lymph nodes • Reactive lymphadenopathy due to infection in the region of lymph node: submandibular lymphadenopathy in tonsilitis or labial heres • General infections( rubella- occipital lymphadenopathy, glandular fever- cervical lymphadenopathy) • Hematologic malignancies: -General lymphadenopathy- lymphoblastic leukemia -Single lymphnode or cluster- lymphoma • Non- infectious disease – Kawasaki disease
