Relationship of Respiratory Symptoms and Signs with Hypoxemia in Infants Under 2 months of Age.

Introduction: Hypoxemia is the most serious manifestation of any acute illness in infants less than two months and has shown to be a risk factor for mortality. Hypoxia can be detected using a pulse oxymeter or arterial blood gas analysis. However this facility is not available in most centers of Nepal. This study has correlated different signs and symptoms to predict hypoxia. Methodology: This hospital based prospective cross sectional study included 160 infant < 2 months, presenting to OPD or Emergency department with any acute illness A complete history was taken and weight, temperature, respiratory rate, heart rate and oxygen saturation was recorded. Presence or absence of nasal flaring, cyanosis, chest indrawing, head nodding, grunting, wheezing and crepitations on auscultation was recorded subsequently. Clinical signs of hypoxemic and non hypoxemic infants were compared and then analyzed. Results: 160 infants, 95 (59.4%) were male and 65 (40.6%) were female. Of the total population, 56(35%) were hypoxic where as 104(65%) were non hypoxic. Infants who presented with more than 3 symptoms, were lethargic, tachypneic or had chest indrawing had higher sensitivity(92.8%, 75%, 75% and 89.3 % respectively) where as infants with nasal flaring, grunting, head nodding or central cyanosis had high specificity (91.3%, 87.5%, 98% and 100%) respectively. Conclusion: Infants presenting with ≥ 3 symptoms, lethargy, respiratory rate of ≥ 70/minute or chest indrawing can be used for screening purpose to detect hypoxia and infants showing signs like grunting, head nodding, nasal flaring or central cyanosis should be considered hypoxic and treated with supplemental oxygen.

Pleural Effusion in Children How often do we suspect Tubercular origin.

Introduction: Pleural effusion is a common problem in children; mostly due to common causes like pyogenic or tubercular infections. Different studies have showed that about 30%-60% of pleural effusion have resulted into formation of empyema. Method: This was an observational study done in children aged 3 months to 14 years with a diagnosis of pleural effusion admitted at Kanti Children’s Hospital, Maharajgunj from August 2009 to March 2010. The aim of the study was done to find out different modalities of treatment for the same and their outcome. A detailed clinical history and physical examination, was done in all children. Chest x-ray, laboratory reports and treatment were recorded and all patients followed up until death or discharge. Any change of management was also noted. Pleural effusion caused by nephritic syndrome or congestive cardiac failure were excluded from the study. Results: During the study period of eight months, 64 patients were admitted with the diagnosis of pleural effusion. Boys to girls ratio was 2:1. Right-sided pleural effusions were more common than left sided pleural effusions (53% vs. 37%). Most of patients improved with parental antibiotics along with chest tube drainage (62%). One in three patients (31%) received anti-tubercular drugs. Three patients (4.6%) were referred to surgeon for decortications and one patient (1.6%) died. Conclusion: Though chest tube drainage with parental antibiotics was the mainstay of treatment of pleural effusion, however one-third of patients also received anti- tubercular drugs.

Children with first episode of fever with seizure: is lumbar puncture necessary?

Fever with seizure, a common presentation with which a child may present to the emergency is mainly due to febrile seizure, but it may also be due to meningitis. This study was done to find out the incidence of meningitis and to find out whether lumbar puncture is necessary in different age groups of children presenting with first episode of fever with seizure. A prospective study was conducted in the emergency department of Kanti Children's Hospital. Children who presented with first episode of fever and seizure in the age group of 6 months to 5 years were included. Meningitis was diagnosed on the basis of either cytological and biochemical criteria or if a bacterial pathogen was isolated. Of the 175 children included, 17% were diagnosed to have meningitis. Cerebrospinal fluid was positive for a bacterial pathogen in 4.5% of the cases. In the age group of 6 months to 12 months, 30% of the children had meningitis as compared to 20 % and 5% in other age groups of 12- 18 months and above 18 months respectively. All children with culture proven bacterial meningitis were in the age group of 6-12 months and had no evidence of meningeal irritation. Signs of meningeal irritation had high specificity in diagnosing meningitis. Organisms grown were Haemophilus influenza in three cases, Streptococcus pneumoniae in two cases and Staphylococcus aureus in three cases. In conclusion, incidence of meningitis was found to be high in children presenting with first episode of fever and seizure. Lumbar puncture to rule out meningitis should especially be considered in children in the younger age group even without evidence of meningeal irritation.
