  26. 26. CLINICAL SUMMARY KA, a 7 month old malay boy a known case of PDA & ASD was admitted to HSB due to shortness of breath one day prior to admission associated with vomiting and chesty cough 2 days prior to admission. On examination, he has signs of mild respiratory distress evidence by tachypnoea (66 breaths/min), subcostal and intercostal recession, on auscultation there was additional sounds - generalise rhonchi heard louder during expiration at right lung posteriorly -generalise crepitation heard louder duing inspiration at both lung anteriorly -Crepitation was louder than Rhonchi
  27. 27. PROVISIONAL DIAGNOSIS Pneumonia Difficulty in breathing Chesty cough, running nose lethargy and poor feeding Preceded by upper respiratory infection Decreased oxygen saturation Signs of respiratory distress Widespread crepitation and rhonci. But crepitation more prominent.
  28. 28. DIFFERENTIAL DIAGNOSIS Differential diagnosis Support Against Bronchiolitis Breathlessness Signs of respiratory distress hyperinflated chest - No fever - No noisy breathing (wheezing) -Crepitations more prominent than rhonci Asthma Breathlessness No fever - no history of asthma no wheezing No family hx of asthma Cardiac failure Breathlessness Signs of respiratory distress no signs of peripheral or central cyanosis.

  37. 37. Discussion
  38. 38. Problems… Preterm Congenital Heart Disease Bronchopneumonia
  39. 39. Complications of Preterm Respiratory Distress Syndrome (RDS) Persistent Ductus Arteriosus (PDA) Necrotizing Enterocolitis Infections Retinopathy of Prematurity (ROP) Apnea and Bradycardia Anemia Bronchopulmonary Dysplasia Hernias and Hydroceles.
  40. 40. ASD & PDA Manifested as: Recurrent chest infection Poor weight gain Tachypnoe Tachycardia Cardiomegaly Collapsing pulse Systolic murmur
  41. 41. Why failure to thrive?
  42. 42. Why recurrent chest infection?
  43. 43. Management of heart disease in the patient Given spirinolactone and furosemide. Was referred to dietician for high calories diet. Appointment in June 2011 with IJN.
  44. 44. Pneumonia
  45. 45. Definition Infection of the lower respiratory tract that involves the airways and parenchyma with consolidation of the alveolar spaces. Highest in infancy, remains relatively high in childhood, low in adult and increases again in old age.
  46. 46. Etiology Virus (common in younger children) RSV Influenza A and B Adenovirus Parainfluenza 1,2,3
  47. 47. Bacteria Age Bacterial pathogens Newborns Group B streptococcus, E. coli, Klebsiella, Enterobacteriaceae 1-3months Chlamydia trachomatis Preschool Strp. pneumoniae, HiB, Staph. Aureus school Mycoplasma pneumoniae, Chlamydia pneumoniae
  48. 48. Microorganisms entry Inhalation of the microbes Aspiration of the organism Hematogenous spread from a distant focus Direct spread from an adjoining site of infection
  49. 49. Types Bronchopneumonia Inflammation of the lung that is centered in the bronchioles and leads to the production of an exudates that obstructs smaller airways and causes patchy consolidation of the adjacent lobules. Lobar pneumonia Pneumonia localized to one or more lobes of the lung in which the affected lobe or lobes are completely consolidated.
  50. 50. Why consolidation occurs?
  51. 51. Symptoms Fever Fast breathing Cough Lethargy Pleuritic chest pain Poor feeding
  52. 52. Signs Tachypnoe Nasal flaring Chest indrawing Dullness on percussion Decreased breath sound Crackles on auscultation
  53. 53. Investigations Full blood count Renal profile Chest X-ray Blood culture Pleural tap analysis Serology
  54. 54. Viral vs Bacterial Characteristics Viral Bacterial Fever Low grade, acute High grade, gradual onset Mucosal congestion and inflammation of upper airway Suggestive Not suggestive FBC WBC normal or mildly elevated, lymphocytes predominance WBC elevated, neutrophils elevated X-ray Usually characteristics of bronchopneumonia Usually lobar consolidation
  55. 55. Treatment Factors like the clinical or investigation findings, age of the child, local epidemiological agents, sensitivity to microbial agents and the severity of the pneumonia should be considered.
  56. 56. Macrolide antibiotic is used if Mycoplasma or Chlamydia are the causative agents. 1 st line Beta-lactam drugs Ampicillin , amoxycillin, benzylpenicillin 2 nd line Cephalosporins Cefotaxime, cefuroxime, ceftazidime 3 rd line Carbapenam Imipenam others aminoglycosides Gentamicin, amikacin
  57. 57. Supportive treatment Nebulized bronchodilators Fluids Must be given in appropriate amount Oxygen Concentration determined by pulse oximetry Anti-pyretic
  58. 58. Others… Had to go to 3 health care centers before getting proper treatments. Mother had to stay away from husband and daughter. Working father had to drive every night to HSB Got tired Economy Leaves daughter with sister in law.
  59. 59. Take home message Treat every patient seriously. Never treat any case lightly. Job is not gained by us, but granted by Allah. Be sincere & always istiqamah.
  60. 60. Thank you
