Admission Patterns and Outcome in a Pediatric Intensive Care Unit in Nepal.

Aims: To study the admission patterns and outcome of children in a Pediatric Intensive Care Unit (PICU) in Nepal. Methods: Demographic profile, diagnosis, treatment, supportive measures and outcome of children admitted to the PICU of B P Koirala Institute of Health Sciences from April 2011 to March 2012 were reviewed. Results: 230 children were admitted to the PICU with male to female ratio of 1.7:1. Diagnoses included respiratory diseases (n=76, 33%), central nervous system diseases (n=43, 18.6%), infectious diseases (n=26, 11.3%), surgical problems (n=18, 7.8%), gastrointestinal diseases (n=17, 7.4%), cardiovascular diseases (n=15, 6.5%), poisonings (n=11, 4.8%), renal (n=9, 3.9%), hematological (n=3, 1.3%) and others (n=12, 5.4%). Out of 230 admitted children, 29 (12.6%) died, 19 (8.2%) left against medical advice and 5 (2%) were referred to other centers. Forty-one (17.8%) children received mechanical ventilation, among which 23 (56%) improved, 14 (34.1%) died and 4 (9.7%) children were taken away by caretakers against medical advice. Conclusion: Respiratory, central nervous system and infectious disease were the common reasons for admission. Children with infectious diseases and need for mechanical ventilation had higher mortality. Therefore, these patients require early referral and timely institution of therapy for better outcome; and intensive care facilities should be expanded to decrease child mortality.

Clinico- Biochemical Profile of Neonates with Birth Asphyxia in Eastern Nepal.

Introduction: Perinatal asphyxia is a common problem with the incidence varying from 0.5 – 2% of live births. It is an important cause of neonatal mortality and is a frequent cause for admission to neonatal intensive care units (NICU). The aims of this study were to find out the clinical and biochemical alterations in different stages of HIE. Materials and Methods: This was a prospective hospital based observational study performed during the period of February, 2010 to January, 2011. Results: Sixty inborn neonates satisfying the criteria for birth asphyxia requiring admission to pediatric wards and neonatal intensive care unit were studied. There were 13(21.7%) cases of mild hypoxemic ischemic encephalopathy (HIE), 27 (45%) moderate and 20 (33.3%) severe HIE. Seizures 41(68.3%), respiratory distress 32(53.3%) and shock 29(48.3%) were predominant manifestations observed. Meconium aspiration syndrome was found in 13.3% of neonates. Hypoglycemia 11(18.3%), hypocalcaemia 7(11.7%), hyponetremia 14 (23.3%) and hyperbilirubinemia 9(15%) were associated biochemical abnormalities. Twenty cases (33.3%) had acute renal failure and they belonged to moderate and severe stages of HIE. Seizures (P< 0.001), respiratory distress (P=0.015), shock (P<0.001) and serum creatinine (P=0.004) were found to be significant among different HIE stages. Conclusion: Neonates having birth asphyxia had HIE, seizures, respiratory distress, shock, hypoglycemia hypocalcaemia, hyponetremia, hyperbilirubinemia and acute renal failure mostly in moderate and severe stages

Portal Hypertension with Visceral Leishmaniasis.

We conducted this study to observe evidence of portal hypertension in children with visceral leishmaniasis (VL). Eighty-eight consecutive cases (50 male) of VL were subjected to ultrasonography. Those with evidence of portal hypertension also underwent upper gastrointestinal endoscopy and liver biopsy. Eight patients had portal hypertension as evidenced by dilated caliber of portal and splenic veins. Two patients had periportal, splenic and peripancreatic collaterals and one patient had cavernous transformation of portal vein. Out of eight patients, four patients had esophageal and gastric varices. Liver biopsy was done in four patients and revealed hepatic sinusoidal dilations without any evidence of fibrosis. Portal hypertension may be an independent manifestation of VL and remain undiagnosed unless a physician maintains a high index of suspicion.

Bone mineral density in children with steroid-sensitive nephrotic syndrome.

Objective. To observe the influence of prednisolone treatment on bone mineral density (BMD) in children with idiopathic nephrotic syndrome. Methods. Duel-energy X-ray absorptiometry of lumbar spine (L1-L4) was performed on 40 patients (18 first episode and 22 relapsers) of steroid sensitive idiopathic nephrotic syndrome. Results. Patients of first episode and relapsers had comparable values of mean age, weight, height, body mass index, serum calcium, phosphate, spine area, bone mineral content (BMC) and BMD. Relapsing nephrotic syndrome patients received significantly higher mean total cumulative dose of prednisolone in comparison to first episode (p<0.001). The BMD Z-scores were normal in 39 of 40 (97.5%) patients. On regression analysis, it was found that both BMC and BMD did not correlate with cumulative dose of prednisolone, when other co-variants such as age, weight, height and spine area were adjusted. Conclusion. Bone mineral density in steroid sensitive nephrotic syndrome is unaffected by cumulative dose of prednisolone therapy both in first episode as well as relapser group of patients.

Dapsone induced methemoglobinemia : Intermittent vs continuous intravenous methylene blue therapy.

OBJECTIVE: The study compares the decline in blood methemoglobin (MetHb) level in children of dapsone intoxication treated with intermittent and continuous methylene blue therapy. METHODS: Eleven children with history of accidental dapsone ingestion and suggestive clinical features of dapsone intoxication were studied. Patients were randomized into two groups: Gr I (n=5) received intermittent methylene blue therapy, while Gr II (N=6) as continuous infusion. The dose of methylene blue was same in both groups. MetHb level in blood was assessed by spectrophotometer at admission and thereafter 12hrly up to 72 hrs. The decline in MetHb was statistically analyzed with student t-test. RESULTS: Six patients had history of seizure and altered sensorium. Severe anemia was observed in 2 patients. The mean levels of MetHb in Gr II was statistically significant after 12, 24, 36, 48 and 72 hrs of methylene blue therapy as compared to Gr I. CONCLUSION: Continuous I.V methylene blue therapy causes significant decline in MetHb level and is more effective in treatment of methemoglobinemia as compared to intermittent regimen.

Deep vein thrombosis with Staphylococcus aureus septicemia.

Deep vein thrombosis (DVT) in children is usually associated with inherited or acquired hypercoagulable state, mechanical obstruction, fractures of long bones, central venous catheterization and prolonged immobility. We report DVT in 4 children with culture proven staphylococcal septicemia. One child died, while other three survived with appropriate antibiotics and anticoagulation therapy.

Miltefosine in children with visceral leishmaniasis: a prospective, multicentric, cross-sectional study.

OBJECTIVE: Miltefosine, an alkyl phospholipid has been found effective against visceral leishmaniasis (VL) in adults in various studies. The authors safety, tolerance and efficacy of Miltefosine and compared with available gold standard anti-Ieishmanial drug, Amphotericin B, a parenteral formulation in children with VL. METHODS: All consecutive children aged 1 yr to 14 yr, presented with fever, splenomegaly and positive LD body in splenic smear examination, admitted in pediatric ward of Nalanda Medical college and Child care center between 1st July 03 to 30th June 05 were taken for study. Patients were randomized into four groups. Group-l and 2 patients were given Miltefosine in dose of 2.5 mg/Kg day o.d. or b.i.d. per orally to a maxiIpum of 100 mg and group 3 and 4 Amphotericin B at a dose of 1 mg/Kg/day (total: 15 mg/Kg). All patients were followed at completion of therapy, 3 months and 6 months for clinical response, splenic size and parasitologically. RESULTS: Out of 125 children, 44 were in group-I, 20 in group-2, 38 in group-3 and 23 in group- 4, 124 patients had parasitological cure with relapse in one patient of group 1 during follow up. One patient in-group II had no response with first course but became parasitologically negative with 2nd course of Miltefosine. In-group I, one patient had persistent splenomegaly and found to have associated portal hypertension. Final cure rate with Miltefosine and Amphotericin B was 93.2%, 95%, 92.1% and 91.3% in-group 1, 2, 3 and 4 respectively, which are statistically insignificant. Majority of patients had pancytopenia. Eievated". AL T (>3 times of normal) were seen in 28, 11, 19 and 13 patients of group 1, 2, 3 and group 4 respectively which returned to normal in subsequent follow up. Raised BUN was observed more in patients who got Amphotericin B i.e. 65.42% and 73.91 % in-group 3 and 4 respectively. GI side effects i.e. diarrhea and vomiting were observed in 26 and 23 patients in-group 1 and 2 respectively. CONCLUSION: Miltefosine is safe, well tolerable, and highly effective and has same efficacy as Amphotericin B in newly diagnosed and SAG resistant children with visceral leishmaniasis.

Immune status with empyema thoracis.

OBJECTIVE: To evaluate the humoral and cell mediated immune status of children with empyema thoracis. METHODS: Serum IgG, IgA, IgM, Complement C3 assay and cell mediated immunity (CMI) tests were performed in 33 patients of empyema thoracis, and 14 healthy age matched controls. RESULTS: The mean serum IgG and IgA levels in empyema thoracis and its subgroups were significantly raised as compared to controls. The overall values of IgG and IgA were 104% (p<0.001) and 114% (p<0.01) of normal mean, respectively. The mean serum IgM and complement C3 levels did not differ significantly in both the groups. The frequency of negative skin reaction to purified protein derivative (PPD) was significantly higher in children with empyema thoracis as compared to controls (p<0.05). The mean absolute lymphocyte count (ALC) was significantly decreased and serum adenosine deaminase (ADA) activity was significantly raised in empyema thoracis in comparison to controls. The overall ALC was 76.1% (p<0.01) and serum ADA activity was 169.4% (p<0.001) of normal mean, respectively. No significant differences were observed in the mean levels of immunoglobulins, complement C3 and CMI tests between pyothorax and pyopneumothorax and pleural fluid culture positive and negative cases. CONCLUSIONS: Thus, both humoral and cell mediated immunity were affected in empyema thoracis patients. However, CMI demonstrated more pronounced change in comparison to humoral immunity.

Bacterial antigen detection test in meningitis.

OBJECTIVE: To evaluate the role of bacterial antigen detection test in cerebrospinal fluid (CSF) for a rapid etiological diagnosis of bacterial meningitis. METHODS: The study included 36 cases of bacterial meningitis and 14 controls. Latex particle agglutination test (LPA test) for detection of bacterial antigen was done in the CSF using slidex meningitis kit (Biomeriux, France). RESULTS: Using LPA test, an etiological diagnosis could be made in 83% cases of bacterial meningitis. In contrast, CSF Gram stain and culture showed 36% and 6% positivity, respectively. The sensitivity and specificity of LPA test were 83% and 100%, respectively. The common etiological organisms were S. pneumoniae, H. influenzae type b and N. meningitidis A. S. pneumoniae was encountered in all age groups while H. influenzae type b was found only below one year of age. CONCLUSIONS: LPA test is a rapid and superior diagnostic tool as compared to CSF Gram stain and culture. The study recommends LPA test as an adjunct laboratory test for rapid etiological diagnosis of bacterial meningitis for prompt institution of proper antibiotics.

Serum immunoglobulin E in early childhood wheezing.

OBJECTIVE: To study the serum Ig E levels in patients presenting with wheezing under the age of 24 months. METHODS: The study was conducted on 38 cases and 35 controls. The children presenting with first attack of wheezing were clinically considered as bronchiolitis and those with recurrent attacks with positive history of atopy in the patient or in their first degree relatives were considered as bronchial asthma. The Ig E estimation was done by immune assay method. RESULTS: The mean serum Ig E was significantly higher in asthma patients (p < 0.001). It was also higher in bronchiolitis patients but the difference was not statistically significant. However, 26 per cent of these patients had values above 1 SD of the control mean. These patients were considered as potential cases of asthma. CONCLUSION: The determination of serum Ig E may be of value in identifying those children presenting with first wheezing attack, who may develop asthma in future. Only a long-term follow-up of these patients can give an answer to the postulation that raised Ig E level at the time of first viral lower respiratory tract infection is a potential marker for the development of recurrent wheezing in later life.

Serum cortisol and thyroid hormone levels in neonates with sepsis.

OBJECTIVE: To evaluate the thyroid hormone and cortisol levels in neonates with sepsis in relation to the final outcome. It was hypothesized that the hormonal level could act as some prognostic guideline. METHODS: Forty nine neonates, aged 8- 28 days, diagnosed as neonatal sepsis were selected for the study. Neonates below 8 days of age, 35 weeks of gestation and 2000 g of birth weight were excluded from the study. Twenty FT-AGA neonates beyond day 7 of life served as control for the study. The hormones were estimated by radioimmunoassay. RESULTS: The neonates with sepsis had significantly higher mean serum cortisol and lower mean serum total T4 at admission as compared to healthy neonates. The mean serum total T3 level was also lower, but the difference was not statistically significant. The mean serum TSH levels were comparable in both groups. The levels normalised following recovery. Sixteen neonates succumbed to the disease process. The non-survivors had significantly lower mean total T3 and total T4 levels as compared to the survivors. CONCLUSION: The endocrinal abnormalities are of transient nature as a response to sepsis. Low total T3 and total T4 are the predictors of adverse outcome in neonates with sepsis.

Reliability of information obtained by illiterate health workers regarding risk pregnancy.

The present study aims at testing the reliability of information obtained by illiterate workers (IHW) on risk pregnancy. Eight maternal risk factors known to be related to low birth weight were utilised for the purpose. The reliability of information obtained by the IHWs were compared with that of the trainer. The reliability proportions (RP) for various parameters ranged from 0.78 to 0.96 with an average of 0.86. For the overall risk assessment, the RP was 0.73. The results of the present study suggest that the IHWs can recorded the risk indicators with fair degree of reliability and accuracy, which may be applied to the training of traditional birth attendants in field settings.

DeSanctis-Cacchione syndrome.

We report a case of DeSanctis-Cacchione Syndrome presenting with unusual features like early onset of cutaneous lesions and optic atrophy.

Meconium stained amniotic fluid: antenatal, intrapartum and neonatal attributes.

OBJECTIVES: To find out the incidence, outcome as well as antenatal, intrapartum and neonatal attributes of meconium stained amniotic fluid (MSAF). DESIGN: Prospective study. SETTING: Neonatal Unit of Hospital. SUBJECTS: 1426 live births occurring in 1500 consecutive deliveries, over one year period. INTERVENTIONS: In all babies born through MSAF, thorough oropharyngeal suction as soon as the head was delivered followed by immediate intratracheal intubation and suctioning in infants depressed at birth. RESULTS: 204 (14.3%) deliveries had MSAF of which thick meconium was present in 141. Hepatitis in mother, fetal distress during labor and intrauterine growth retardation were significant factors associated with MSAF. One fifth of babies born through MSAF suffered severe birth anoxia compared to 5.6% in non-MSAF group. The consistency of meconium had direct bearing on the neonatal outcome. Severe birth asphyxia (SBA) occurred in 27.0 and 6.3% of babies with thick and thin meconium staining, respectively. Meconium aspiration syndrome was observed in 9 babies of thick meconium group and 8 of these were depressed at birth. All deaths occurred in thick meconium group and were associated with SBA. CONCLUSIONS: Selective approach can be adopted for babies with MSAF reserving intratracheal suctioning at birth for depressed neonate or evidence of fetal distress in utero. Rest of the neonates only need careful observation after thorough oronasopharyngeal suctioning.

Cerebrospinal fluid adenosine deaminase activity and C-reactive protein in tuberculous and partially treated bacterial meningitis.

Adenosine deaminase (ADA) activity measurement and C-reactive protein (C-RP) detection were done in CSF of 27 tuberculous meningitis (TBM) and 8 patients of partially treated bacterial meningitis, apart from routine biochemical tests. Both the groups had comparable CSF cell count, protein and sugar concentrations. The mean CSF ADA activity was significantly raised in TBM as compared to partially treated bacterial meningitis patients (p < 0.05). A cut-off ADA level < or = 5 IU/L and C-RP positively were used for differentiation of partially treated bacterial from TBM cases. Based on this, the sensitivity and specificity of ADA and C-RP were 62.5%, 88.9% and 75%, 100%, respectively. Since both the tests are simple and take lesser time to perform, they can be used as rapid diagnostic tests to remove diagnostic dilemma between the two diseases.

Adenosine deaminase activity in typhoid fever.

Serum adenosine deaminase (ADA) activity was determined in 41 patients of typhoid fever and 15 normal controls. The mean ADA activity was significantly raised in typhoid fever patients as compared to controls (p < 0.001). The peak enzymatic activity was observed in the first week of illness. Complicated patients had lower mean ADA activity at diagnosis as compared to uncomplicated group and they showed a rise in enzyme level during defervescence, repeated in a few cases. A significant correlation between serum ADA activity and lymphocyte percentage was found (r = 0.4245, p < 0.001). It is concluded that ADA activity in typhoid fever patients not only indicates immunity but also has a prognostic value.
