Neonatal mechanical ventilation: Indications and outcome.

BACKGROUND AND AIMS: Decreasing mortality in sick and ventilated neonates is an endeavor of all neonatologists. To reduce the high mortality in this group of neonates, identification of risk factors is important. This study was undertaken to find out the indications of ventilation and complications in ventilated neonates and also study possible predictors of outcome. SUBJECTS: Age <1-month; mechanically ventilated; not having suspected metabolic disorders or congenital anomalies; excluding postoperative patients. METHODS: Neonates consecutively put on mechanical ventilation during the study period (October 2011 to November 2013) enrolled. Primary disease of the neonates along with complications present listed. Clinical and laboratory parameters analyzed to find the predictors of mortality. RESULTS: Total 300 neonates were ventilated. 52% were male. Mean age, weight, and gestational age were 21 ± 62 h, 2320 ± 846.2 g, and 35.2 ± 4.9 weeks, respectively. 130 (43%) neonates died. Respiratory distress syndrome (RDS) (31.1%), sepsis (22.7%), and birth asphyxia (18%) were the most common indications for ventilation. Mortality in ventilated patients with sepsis, pneumonia, RDS or birth asphyxia was 64.7%, 60%, 44.6%, and 33.3%, respectively. Weight <2500 g, gestation <34 weeks, initial pH <7.1, presence of sepsis, apnea, shock, pulmonary hemorrhage, hypoglycemia, neutropenia, and thrombocytopenia were significantly associated with mortality (P < 0.05). Resuscitation at birth, seizures, intra ventricular hemorrhage, pneumothorax, ventilator-associated pneumonia, PO2, or PCO2 did not have a significant association with mortality. On logistic regression, gestation <34 weeks, initial pH <7.1, pulmonary hemorrhage, or shock were independently significant predictors of mortality. CONCLUSIONS: Weight <2500 g, gestation <34 weeks, initial arterial pH <7.1, shock, pulmonary hemorrhage, apnea, hypoglycemia, neutropenia, and thrombocytopenia were significant predictors of mortality in ventilated neonates.

Role of electroencephalogram and neuroimaging in first onset afebrile and complex febrile seizures in children from Kashmir.

OBJECTIVES: (1) To determine the frequency of abnormal neuroimaging in children with new-onset afebrile and complex febrile seizures; (2) to draw a correlation between Electroencephalogram (EEG) and neuroimaging. STUDY DESIGN: A hospital-based prospective study. MATERIALS AND METHODS: A total of 276 children (6 months to 14 years of age), who presented with new-onset afebrile or complex febrile seizures, underwent EEG and neuroimaging [Computed Tomography (CT) and/or Magnetic Resonance Imaging (MRI)]. RESULTS: Generalized seizures constituted the major seizure group in our study - 116/276 (42%) - followed by partial seizures 86/276 (31.2%) and complex febrile seizure in 64/276 (23.2%). Generalized as well as partial seizures were more common in children aged 6-14 years, while complex febrile seizures were predominantly seen in children less than 6 years old. Most of the patients with generalized and partial seizures had EEG abnormalities, while EEG abnormalities were uncommon in patients with complex febrile seizures. A total of 27/276 (9.8%) patients with seizure disorder had abnormal CT scans and this abnormality was more common in patients with partial seizures. CT abnormality was seen more commonly in those patients who had an abnormal EEG. EEG and CT correlation showed that patients with abnormal EEG had higher rates of CT abnormality, ie, 16.1% (25/155). Abnormal MRI was seen in 32/157 (20.4%) of patients; accuracy of picking abnormality by MRI, when EEG was abnormal, was 24.8% (P<0.05). CONCLUSION: Our findings indicate that clinical examination and EEG results are good indicators for neuroimaging, and these can be used as one of the criteria for ordering neuroimaging in new-onset seizures.

High prevalence of BCR-ABL fusion transcripts with poor prognostic impact among adult ALL patients: report from Pakistan.

AIM: Philadelphia (Ph) chromosome positive acute lymphoblastic leukemia (ALL) is a common cytogenetic abnormality associated with poor outcome in adults. This preliminary study, in the absence of substantial evidence, reported the prevalence of the BCR-ABL gene fusion in ALL patients by RT-PCR in Pakistan. Moreover, the prognostic significance of BCR-ABL fusion along with other characteristics was also ascertained. METHODS: One hundred forty six newly diagnosed ALL patients treated at our center between 2005 and 2008 comprised the study group. The patients were treated with a Children and Leukemia Group B induction regimen. RESULTS: Among these patients, BCR-ABL fusion oncogene was present in 43 of 78 patients (55%). A statistically significant difference in BCR-ABL-positivity within three age groups (<20 years, 20-50 years, >50 years) was observed (P= 0.001). The median age was significantly higher in the BCR-ABL+ group (30 vs 19 years; P= 0.001). BCR-ABL+ patients were also characterized by higher median WBC counts (96,000/µL vs 23,000//µL, P= 0.002). Complete remission was achieved in 74% BCR-ABL- patients and 35% BCR-ABL+ patients (P= 0.001). Only 10% of BCR-ABL- patients achieved continued complete remission (CR). None of the BCR-ABL+ patients maintained a CR further to induction therapy. With the available therapeutic protocol, the presence of a BCR-ABL fusion predicted a lower survival (P= 0.001). CONCLUSION: A high prevalence of BCR-ABL gene fusion was observed that appeared as a poor prognostic factor. Identification of this genetic entity at diagnosis is crucial for understanding the nature of adult ALL and for deciding optimal treatment.

Snake bite envenomation in children in Kashmir.

A three year retrospective study was done to study snakebite envenomation among Kashmiri children. Ten children were admitted with snakebite. Snakebite was vasculotoxic in seven and mixed in two. Levantine viper bites were seen in five who had Grade 3 bites with severe local signs, severe coagulopathy and hypotension. Both environmental risk and seasonal incidence was observed.

Nosocomial sepsis-induced late onset thrombocytopenia in a neonatal tertiary care unit: a prospective study.

BACKGROUND AND OBJECTIVES: Late onset sepsis (LOS)( onset of sepsis >72 hours of age or nosocomial sepsis) is an important cause of morbidity and mortality in the neonatal intensive care unit (NICU). Thrombocytopenia is an important complication of sepsis. We investigated the incidence of thrombocytopenia in LOS patients and studied the influence of various parameters on platelet response. PATIENTS AND METHODS: Infants born in the level 3 neonatal intensive care unit between January 2002 and December 2006 with documented LOS were included in this prospective study. Multiple hemograms with platelet counts, bacterial blood culture and fungal blood culture were obtained in all patients. Demographic and clinical data were compared between patients without thrombocytopenia and with mild, moderate and severe thrombocytopenia. Duration of thrombocytopenia in relation to type of organism and mortality with respect to degree of thrombocytopenia were also studied. RESULTS: Of 200 patients with culture-proven nosocomial sepsis, 119 (59.5%) patients developed thrombocytopenia (platelet count <150 X 109/L). In our series Klebsiella pneumoniae was the most frequently isolated organism (125/200, 62.5%) and the incidence of thrombocytopenia was 60.0% (75/125). However, the incidence of thrombo- cytopenia was highest among patients who had concurrent bacterial and fungal sepsis (28/31, 90.3%). Coagulase- negative staphylococcal (CoNS) sepsis was present in 21 (10.5%) patients and the incidence of thrombocytopenia was 33.3%. Isolated fungal sepsis was present only in 6 (3%) patients and the incidence of thrombocytopenia was 66.0%. The incidence of thrombocytopenia was highest among preterm babies and low-birth weight (LBW) babies. Twenty-seven percent (54/200) of babies presented with mild thrombocytopenia, 20% (40/200) presented with moderate thrombocytopenia, and 12.5%(25/200) developed severe thrombocytopenia. Severity of thrombocytopenia was also directly related to the presence of necrotizing enterocolitis (NEC) and disseminated intravascular coagulation (DIC). The mortality rate was significantly associated with the degree of thrombocytopenia. CONCLUSION: LOS sepsis is an important risk factor for thrombocytopenia in the NICU. Fungal and gram- negative sepsis are frequently associated with a decreased platelet count. Sepsis-induced thrombocytopenia is more common among LBW babies and preterm babies. The mortality rate is significantly related to degree of thrombocytopenia.
