Stenotrophomonas maltophilia: More than Just a Colonizer!

Stenotrophomonas maltophilia is an emerging gram-negative pathogen that was previously labeled as a colonizer. Nowadays, with multiple antibiotic usage along with certain host factors, infections caused by this organism are getting attention. We hereby report two cases of ventilator-associated pneumonia in postoperative infants by Stenotrophomonas maltophilia in a cardiac intensive care unit (ICU).

Peripheral neuropathy in children on stauvudine therapy

OBJECTIVE

To assess the prevalence of peripheral neuropathy in HIV infected children (>5 y) receiving stavudine-based combination anti-retroviral treatment (ART) for more than 3 mo in a cross-sectional study.

METHODS

History, detailed neurological examination and nerve conduction studies were performed.

RESULTS

Forty children [26 boys; median age - 11.75 y, Inter quartile range (IQR): 9-16 y] were enrolled. The median duration of ART was 43 mo [IQR: 18-69 mo]. The nerve conduction studies were abnormal in four children (10 %). Symptomatic distal sensory polyneuropathy was present in two children, asymptomatic distal sensory polyneuropathy and subclinical distal sensory polyneuropathy was present in one child each.

CONCLUSIONS

Distal sensory polyneuropathy is a potential problem in children on stavudine based ART. Children on stavudine based ART need periodic clinical and electrophysiological screening for its early detection.

Concerns on the dosing of antitubercular drugs for children in RNTCP

The Revised National Tuberculosis Control Program (RNTCP) has initiated provision of antitubercular therapy for children with strategy of patient-wise boxes for the 4 different weight bands (6- 10 kg; 11- 17 kg; 18- 25 kg; 26- 30 kg). We evaluated the dose of individual drugs delivered by this approach to children of varying weights. The following areas of concern were identified: underdosing of individual antitubercular drugs for many weights; lack of provision to modify doses when child gains weight and moves to another weight band; and, inappropriate formulations, particularly for infants. We conclude that the current dosing strategy used in RNTCP needs modification to prevent the significant risk of underdosing and undertreatment.

Dermoid cyst of the tongue: report of a case

The case of a young patient with an intralingual dermoid cyst is presented. The peculiarities of this case are the large size of the cyst, leading to macroglossia, the patient's inability to close the mouth, and the resultant difficulty in speech and swallowing.
