Assessment of various intralesional injections in keloid: comparative analysis.

 : In reaction to skin injury in genetically predisposed persons, the keloid is formed and marked by benignant overgrowth of dermic collagen. Intralesional triamcinolone was used in the treatment of keloids with varying results. AIM: Intralesional triamcinolone is a gold standard in treating the keloids in comparison with its effectiveness versus intralesional 5-fluorouracil intralesional verapamil and intralesional platelet-rich plasma. PATIENTS AND METHODS: Several 160 cases were categorized into four groups of each group-containing 40 cases. Group-A (control) treated with intralesional triamcinolone and Group-B intralesional verapamil, Group-C intralesional 5-fluorouracil, and Group-D intralesional platelet-rich plasma. Patients were assessed for clinical response based on a decrease in the patient and observer scar assessment scale (POSAS) at baseline and the end of treatment. RESULTS: The mean base-line POSAS score was 91 ± 10.98 SD check-in Group-A, 90 ± 10.85 in Group-B, 89 ± 10.06 in Group-C, and 92 ± 10.84 in Group-D. POSAS score after 24 weeks 36 ± 12.74 in Group-A, 29 ± 10.91 in Group-B, 39 ± 13.74 in Group-C, 36 ± 12.74 in Group-D. Statistically, a significant difference was observed between groups. CONCLUSION: Intralesional verapamil reported to be the most effective therapy and platelet-rich plasma was effective as intralesional triamcinolone acetonide with no serious side effects and 5-fluorouracil was less effective in treating the keloids.

Assessment of neopterin level and severity in lichen planus patients treated with narrow-band ultraviolet B.

BACKGROUND: Neopterin is a cellular immunity biochemical marker. Serum and saliva neopterin levels have been reported to increase in lichen Planus. Nonetheless, analysis has not yet been made for the direct link between narrow band ultraviolet B and severity of Lichen planus. AIM: We aimed to assess serum neopterin levels in patients who receive narrow band ultraviolet B therapy treatment with lichen planus, paired with the severity of the disease. PATIENTS AND METHODS: The study consisted of 35 lichen planus patients and 30 healthy individuals. A 35 patient group received narrow band ultraviolet B therapy. An enzyme-related immunosorbent assay procedure was used in serum neopterin analysis before and post-therapy. RESULTS: The correlation between the level and severity of the patient group was statistically significant (P = .001). In patients with severe disease, serum neopterin levels were significantly increased. Also, in the severe lichen planus group, the serum neopterin level was statistically higher than that of the mild or moderate groups (P = .001).Also, a significant decrease was seen following therapy according to serum neopterin level. CONCLUSION: Serum neopterin levels are a useful marker for the assessment of the severity and effectiveness of narrow band ultraviolet therapy. Thus, our findings may provide a new approach with the management of disease and follow-up strategies in patients with lichen planus.
