Unit 28 will take you through the evaluation of common childhood problems. Cardiovascular, haematologic and renal disorders are discussed in Unit 29, while gastrointestinal, liver and neurologic problems are presented in Unit 30. Tuberculosis and HIV are emerging childhood problems which are discussed in Unit 31 and Unit 32. Paediatric emergencies such as resuscitation, poisoning, accidents, etc. are reviewed in Unit 33 of this block. Finally, the Unit 34 on common paediatric surgical problems gives you an insight about the possible surgical procedures.

Therefore, a step wise approach is required to make differential diagnosis and plan investigations. In this unit, a symptom-wise approach is used to enable you to make a clinical diagnosis of some common problems. Other common conditions are. described in brief. You are required to refer to standard text books for the detailed discussion of these disorders. 5 ChildhoodMorbidity 28.2 CHILD WITH FEVER Fever is the commonest presenting symptom in children. Fever is defined as elevation of body temperature in response to a pathological stimulus. Conventionally temperature >38°C is called fever. Fever greater than 41.5°C is called hyperpyrexia and warrants aggressive antipyretic treatment because of risk of irreversible organ damage, Children presenting with fever can be di\!ided into three groups: (i) acute fever with obvious focus such as tonsillitis or pneumonia etc. (ii) acute fever with no localizing sign or non-specific signs and (iii) prolonged fever of unknown origin. It is the latter two groups which pose diagnostic problem. While evaluating the patient with fever the first important thing to consider is the age of the patient. Acute fever in an infant less than 2 months should always arouse suspicion of serious bacterial infection presence of petechial haemorrhages at any age is also indicative of serious illness and necessitates hospitalization. The other important consideration is duration of fever. Important causes of fever of short duration (2 weeks) and prolonged fever are listed in Table 28.1. The common causes of acute fever are malaria, viral illness( may also cause upper respiratory infection and diarrhea) and bacterial infections such as typhoid fever. 28.2.1 Common Causes of Fever The common causes of fever are given in Table 28.1. We shall learn more about these causes in the subsequent sub-sections. Table 28.1: Common Causes of Fever in Children Causes of fever of short duration Prolonged fever ( <2 weeks) ( >2 weeks) Infections Malaria Typhoid. Respiratory infection e.g. Kala-azar Tonsillitis Malaria Pneumonia Tuberculosis Otitis Media UTI Viral Exanthem Bacterial endocarditis Typhoid fever Abscess in liver Urinary Tract Infection (UTI) Brucellosis Heat hyperpyrexia Infectious mononucleosis Occult pyogenic infection Connective tissue disorders e.g. abscess Rheumatoid arthritis 6 Common Paediatric Meningitis SLE, Kawasaki disease Problems Neoplastic Condition e.g. Leukaemia, lymphoma Others Drug fever Thyrotoxicosis Immune deficiency-HIV Diabetes Insipidus 28.2.2 Acute Fever Evaluate for any focus of infection. Determine whether the child is seriously ill? A sick child has one or more of following symptoms and signs: Symptoms Signs Lethargy “sick” or toxic look Inability to suck lethargy/poor tone Irrititability weak cry Drowsiness tachypnoea poor peripheral perfusion The fundamental basis of diagnosis is to localize the infection by careful history and clinical examination. It should also be remembered that in children disease develops over hours and days and a single examination may not provide the diagnosis. Where there is a doubt, the child should be hospitalized and reexamined. In a small but significant proportion of children no identifiable cause of fever is found even after detailed examination. This problem is more common in infants and toddlers. The common causes of acute fever without obvious focus are viral illness, malaria, otitis media, typhoid fever, occult bacteremia. The diagnosis can be then established by (i) obvious focus such as tonsillitis or pneumonia etc. (ii) acute fever with no localizing sign or non-specific signs and (iii) prolonged fever of unknown origin. It is the latter two groups which pose diagnostic problem. In areas endemic for malaria, empirical therapy for malaria may be started. In case laboratory investigations are not available treatment is often based on clinical diagnosis. Occult bacteremia implies presence of bacteria in the blood stream with minimal clinical signs.
