BACKGROUND. Chronic rhino-sinusitis (CRS) is a common inflammatory disease of the
nose and paranasal sinuses, especially after virus infections. It has a significant impact
on patients’ quality of life. We aimed to evaluate the clinical value of low-level laser
therapy (LLLT) forpediatric chronic rhino-sinusitis.
METHODS. 30 patients 6-15 years old with CRS were divided into two groups: T1 were
treated twice a week and T2 were treated five times a week for 2 treatment sessions
within 2 weeks. Laser irradiation was delivered on 12 points over each maxillary and
frontal sinuses with 30 seconds and the total treatment duration was 180 seconds. The
evaluation was performed by a total symptom score based on SNOT-22 questionnaires
of pre and after treatments.
RESULTS. The total symptom scoreimproved significantly (p<0.15) in 27 cases.
CONCLUSION. This study indicates that LLLT applied for 4 weeks improves symptoms in
patients with CRS. LLLT is one of the most cost-efficient and painless treatment methods
for pediatric rhino-sinusitis.

Background:
Vitamins are nutrients essential for human health. They act as coenzymes that help trigger important chemical reactions necessary for energy production. Reference values for vitamins help physicians evaluate the health status of patients and make clinical decisions. The aim of this study was to determine the mean values and reference intervals for some water-soluble vitamins of Mongolian adults.
Materials and Methods:
Three hundred and forty healthy adults (170 males and 170 females) of 17 to 69 years of age were selected for the study based on CLSI C28-P3 criteria Defining, establishing & Verifying reference interval in the clinical laboratory; Proposed Guidelines. The study was approved by the Resolution No.76 of 2018 of the Medical Ethics Review Committee of the Ministry of Health. Informed consents were taken from the selected individuals. Morning blood samples of the participants were collected under aseptic conditions. Levels of vitamins B6, B9, B12 and vitamin C were measured using a high performance liquid chromatography method. The lower- and upper reference limits were defined as the 2.5th and 97.5th percentiles, respectively. The data were analyzed using SPSS and Excel programs.
Results:
The mean blood level of vitamin C was 11.88 mg/L (95% CI 10.47-13.29) for men and 9.62 mg/L (95% CI 8.11-11.13) for women. The calculated reference interval for males was 1.40-19.40 mg/L and 1.17-18.04 mg/L for females. The mean concentration of vitamin B12 in the blood of males was 938.45 ng/L (95% CI 747.22-1129.68) and that of females was 864.03 ng/L (95% CI 603.81-1124.25). The reference interval for vitamin B12 was 233.03-1597.00 ng/L in men and 132.45-1623.86 ng/L in women. The mean level of vitamin B9 was 8.47 ng/mL (95% CI 5.64-11.30) for men and 6.91 ng/mL (95% CI 4.89-8.93) for women. The calculated reference interval for this vitamin in males was 1.04-24.74 ng/mL and that in females was 1.04-21.46 ng/mL. As for vitamin B6, the mean concentration for men was 44.42 ng/mL (95% CI 37.01-51.83) and for women was 34.67 ng/mL (95% CI 29.97-39.39) with the reference intervals of 5.90-79.02 ng/mL for men and 5.27-61.72 ng/mL for women.
Conclusion
The reference values for vitamins B6, B9, B12 and vitamin C of Mongolian adults do not differ significantly from those observed in other populations. The calculated reference intervals can be used in the practice of health laboratories.
