BACKGROUND: Effectiveness of low level nitrogen laser therapy along with antitubercular treatment (ATT) in cases of treatment failure and drug resistant tubercular lymphadenopathy, sinuses and cold abscess.
METHODS: In a double-blind randomized controlled trial of LLLT, 104 patients assigned to either the low level nitrogen laser therapy along with ATT (LLLT group) (n = 54) or ATT only (Chemotherapy group) (n = 50). Both groups were treated two times per week for five weeks. Those in the treatment group received pulse nitrogen laser with a pulse duration of seven nanosecond, wave length 337 nanometer and average power output of 5 mW whereas those in the control group were treated with sham laser. The primary outcome measure was bacteriological conversion and the secondary outcome measures were decrease in size of lesion and the clinical improvement.
RESULTS: Acid Fast Bacilli (AFB) smear, AFB culture and Polymerase Chain Reaction (PCR) conversion rate at five weeks (after 10 sittings of laser) were 49.15%( Fishers P exact test-p = 0.015), 60%, 44.44% (Fishers P exact test-p = 0.048) in LLLT group as compared to 11.86%, 20%,17.77% in chemotherapy group. Average percentage reduction in the size of gland at 5 weeks was 70.67% (p value 0.01) as compared to 54.81 in chemotherapy group. Average time taken for closure of sinuses was 11.03 weeks in LLLT group as compared to 26 weeks in chemotherapy group. The follow up was conducted for two years.
CONCLUSION: Low level nitrogen laser therapy can be used as an adjunctive therapy along with antitubercular drugs in cases not responding and drug resistant tubercular lymphadenopathy, sinuses and cold abscess.

Low-intensity infrared laser radiation in the diagnosis and combined treatment of acute nonspecific lymphadenitis of the face and neck in children
[Article in Russian]
Oasevich IA, Shargorodskii AG.
Clinical course of acute nonspecific lymphadenitis of the face and neck is studied in 241 patients aged 1-14 years in order to improve the diagnosis and therapy of this condition. General clinical examinations were supplemented by laser biophotometry and assessment of the activities of some local defense factors (lysozyme, beta-lysine, secretory and serum IgA). Multiple-modality treatment for the first time included magnetic laser therapy (MLT), and its efficacy is assessed. Results of biophotometry helped define objective criteria for the diagnosis and evaluation of treatment efficacy in children with acute lymphadenitis of the face and neck. MLT proved to be a highly effective treatment modality, decreasing the inflammation and correcting local (oral) defense factors. Use of MLT accelerated all phases of the inflammatory process, promoted its regression at the serous stage, and decreased the incidence of suppurative forms of acute lymphadenitis by 40%.
