Lymphopenia and Severe Combined Immunodeficiency (SCID) - Think Before You Ink.

Objectives: Severe combined immunodeficiency (SCID) represents one of the most severe forms of Primary immunodeficiency (PID) disorders, characterized by T cell lymphopenia (TCL) and lack of cellular and humoral immune responses. However, not all patients with low T cell lymphocyte counts may have an abnormal T cell immunity and the observed TCL may be a temporary suppression resulting from transient lymphopenia secondary to severe infections. In such cases, it is necessary to estimate the severity of the observed TCL by assessing thymic capabilities.

Effect of propofol titration v/s bolus during induction of anesthesia on hemodynamics and bispectral index.

Background: Propofol when given as 2 mg/kg IV bolus for induction of anesthesia is known to cause hypotension requiring vasopressors. The objective of our study was to compare Propofol 2 mg/kg single IV bolus (Precalculated group, PG) with the titration of Propofol (Titration group, TG) to clinical parameters as 10 mg IV increments every 3 seconds on hemodynamic Parameters and Bispectral Index (BIS), during induction. The effect of titration on dose requirement for induction was also evaluated.

Summary of invasive pneumococcal disease burden among children in the Asia-Pacific region.

Invasive pneumococcal disease (IPD) burden is significant in the Asia-Pacific region. This review describes the epidemiology and Streptococcus pneumoniae (SP) serotype distribution of IPD in children in the Asia-Pacific region from studies published from 1999 to 2010. IPD incidence varies widely in Asia-Pacific countries depending on the method of surveillance, the population studied, and the time period.

Carbon dioxide absorber as a cause of high airway pressures.

We investigate an incident in which a carbon dioxide absorber caused difficulty with ventilation. The problem as it developed throughout the anesthetic, and clues that led to the determination that the carbon dioxide canister was the problem, is discussed.

The use of a laryngeal mask airway after a prolonged suspension laryngoscopy to preserve a vocal cord fat graft.

A 62-yr-old man presented for a microdirect laryngoscopy and vocal cord fat grafting under jet ventilation. After a prolonged laryngoscopy, the patient developed hypercapnea and upper airway obstruction secondary to traumatic epiglottitis. The placement of a laryngeal mask airway provided ventilation and allowed for direct visualization of the patient's inflamed epiglottis without disruption of the patient's fat graft.

Adolescent vaccination.

Indian Academy of Pediatrics (IAP) has taken an important step towards adolescent vaccination. In the present article, the author has briefly described the needs for adolescent immunisation along with the IAP vaccination schedule for adolescents, in details.

H. influenzae type b (Hib) vaccine--controversies.

Hib vaccine is the 8th vaccine knocking at the door to be included in the EPI the world over. However there are some controversies that need to be addressed, especially when it comes to use of this vaccine in India. It is difficult to culture Hib unless one uses sheep blood enriched media for culture.
